    SUPPORT ELEMENT FOR SCREW THREAD CONCERNING CLOSURES Field of the invention
    The proposed invention is in the field of closures provided with a screw thread. The use of this invention for closures of containers is particularly interesting.
    Background to the invention
    Opening conventional threaded closures can be challenging and unpleasant for a variety of reasons. Opening a threaded closure requires considerable force, which consists of a lateral pressure on the side wall or handle of the closure for grip, and a torsional force for the actual release of the closure. The degree of grip on the closure is determined not only by the applied lateral force, but also by the size and shape of the surface of the side wall or the handle of the closure. A threaded closure has an upper wall, a thread support element, and a thread. The thread support element is an annular collar that extends from the upper wall and which supports the thread. When the thread is provided on an inner surface of the threaded support element, the outer surface of the threaded support element can serve as a surface for manipulations and applying torsion (e.g., closing or opening the closure). The screw thread may be provided on an external surface of the thread support element, in which case the cylindrical wall of the closure does not necessarily serve as a surface for manipulation; a handle can be provided to accomplish this function. Most presently available threaded closures have protrusions for grip on their thread or handle support member. These elements are intended to increase friction, and thus reduce the required amount of lateral force. Often, these protrusions for grip are fine, numerous, and positioned longitudinally because the aforementioned properties contribute to increase grip. Because these protrusions are additionally placed on the closure for grip, this requires a considerable amount of additional material for the manufacture of such closures. Most closures are made of plastic such as high density polyethylene, low density polyethylene, polypropylene and the like. The use of the aforementioned materials is not environmentally friendly.
    Due to the presence of protrusions for grip on closures, the manipulation of these closures is often experienced as unpleasant. This is partly due to the fact that pressing fingers with a relatively high force on the edges of the protrusions causes an inconvenience for grip. This perceived discomfort is one of the reasons why most closures of cosmetic products do not have protrusions for grip. Most cosmetics-producing companies avoid any element that could cause a reduction in the consumer's pleasant experience (eg soft feel of the product).
    The total cost of producing a threaded closure includes energy and a quantity of material. The cost of the amount of material used is greater than the energy cost. Consequently, any reduction in the amount of material used has a significant effect on the total production cost of closures. A reduction in the amount of material used cannot be performed indiscriminately because it may cause a loss of function or quality. In addition to economic considerations, partly as a result of increasing strict environmental regulations, the use of large quantities of plastics is discouraged.
    In addition to economic and environmental considerations regarding the production of threaded closures, the additional use of grip protrusion material causes a significant increase in the mass of the closure. This increase in mass makes transport (such as from the production plant from the closure to the filling factory of containers, from the filling factory from containers to the wholesaler, from the wholesaler to the department store, from the department store to the consumer, from the consumer to the waste factory , etc.) more expensive and more energy consuming.
    When a container that is under pressure (e.g. when the content is a carbonated liquid) is opened there is an escape of gas. Because the gas cannot escape smoothly with conventional closures, consumers take extensive time to open the cap very slowly.
    Companies distinguish themselves by, among other things, the characteristic properties of their closures. This can be a specific shape, color and size of a closure. Most companies display text, logos, advertising, etc. on the top wall of their closures. This is not an efficient form of communication since the top wall of the container closure is not clearly visible in an upright position (as is the case most of the time, such as in the shelves of department stores, in refrigerators, etc.). Although the threaded support element is more clearly visible when the container is in an upright position, it is not possible today to portray things on the threaded support element in view of the need for protrusions for grip. US 6253942 B1 and US 6811047 B1 are attempts to create large, smooth handles that provide sufficient grip so that protrusions for grip are not needed, but they have many disadvantages. The production of these large handles requires an amount of material that is larger than the necessary amount of material for conventional protrusions for grip. This increases the production and transport costs of these closures. Another disadvantage of these large handles is that they can disrupt the design of the container, making it appear less streamlined. The presence of large handles on the container closures can make stacking, storage and manipulation more difficult. GB 189912520 A, US 1207560 A, US 4469235 A, US 4534477 A, US 4731512 A, US 5184740 A, and US 20140263317 A1 are attempts to replace the protrusions for grip on the threaded support element with longitudinally protruding handles on the upper wall of the closures, but they have many drawbacks. The need for a minimum length for these elements to be easy to handle ensures that a substantial amount of material is required that is comparable or greater than the necessary amount of material for protrusions for grip. Another disadvantage of longitudinal handles is that they can disrupt the design of the container, making it appear less streamlined. The presence of longitudinal handles on the container closures can make stacking, storage and manipulation more difficult.
    There are several inventions that have attempted to create a smooth outflow of gas when a container is opened, something that is particularly interesting for opening pressurized containers. The use of an interrupted thread, as described in patents US 4643330 A, EP 0263699 B1, US 6006930 A, and US 20120091138 A1, are examples of this, but they have many disadvantages. The interrupted thread may be provided on the neck of the container, the closure, or both. Although an interrupted thread allows a larger outflow of gas compared to a continuous thread, the outflow of gas is still limited and not smooth. Another drawback of an interrupted thread is that the total surface area of the thread is reduced, which causes a reduction in the degree of retention. If the total length of the thread is made longer to compensate for the reduction in the degree of retention, an adjustment of the design of the neck of the container or of the screw support element of the closure may be necessary. US 20100200532 A1 is an attempt to reduce the amount of material used for the production of closures while preserving most of the functions and strengths, but it has many disadvantages. In patent US 20100200532 A1 the support element for screw thread has folds. In order for these folds to offer sufficient grip, they must be numerous and provided with sharp edges. As a result, one of the drawbacks of this invention is that pressing fingers on the surface with creases is unpleasant and does not give a soft feeling. Although it is suggested that when creases are provided in the threaded support member there is a reduction in the required amount of material used for the production of closures, this reduction is very limited. Because there are folds in the thread support element, this increases the surface area and therefore also the total volume of the thread support element. Although the protrusions are omitted for grip, and there is thus a reduction in the necessary amount of production material, there is an increase in the volume of the thread support element. Consequently, the amount of production material saved is very limited in comparison with protrusions for grip. Another drawback is that a threaded support element with pleats limits the design options of the closure and may make the overall appearance of the closure less attractive.
    There is a need for a low weight closure that gives a soft feel while providing sufficient grip, allowing a smoother outflow of gas, and where it is possible to depict visual elements on the threaded support element.

Other embodiments can be used, and structural or logical changes can be made based on the scope of the proposed invention. The detailed description below is therefore not limiting, the scope of the proposed invention is determined by the patent claims.
    The proposed invention relates to threaded closures. The closure is for an object such as a container. The closure is preferably for hermetically closing a container, in particular for closing a container opening. A threaded closure according to the invention comprises an upper wall and a threaded support element which extends from the upper wall and which connects to the complementary thread of the object such as a container. The thread support element connects the thread of a closure to its upper wall. The threaded support element comprises at least one separate recess - an empty space below a surface of the threaded support element - which partially or completely extends over the wall of the threaded support element. A separate recess that extends completely over the wall of the threaded support member is referred to as a window. A separate recess reduces the weight of the closure, provides a surface for grip (in the case of an internal thread) while maintaining the soft feel of the closure, allows a smooth passage of gas (in the case of windows), and / or allows to visualize visual elements on the threaded support element.
    When the thread is provided on an inner surface of the threaded support element, the outer surface of the threaded support element can serve as a surface for manipulation and applying torque (e.g., closing or opening the closure). The screw thread may be provided on an external surface of the thread support element, in which case the cylindrical wall of the closure does not necessarily serve as a surface for manipulation; a handle can be provided to accomplish this function.
    Embodiments of the invention give a closure a low weight without there being a loss of functions (e.g., no change in the degree of retention, comparable durability, etc.). This reduction in mass is achieved by omitting or reducing protrusions for grip, and by reducing the material volume of the thread support element. This reduction in mass reduces production and transport costs, and makes these closures more environmentally friendly. Embodiments of the invention offer a higher grip (in the case of an internal thread) because of the possibility of having a surface for grip in multiple directions (e.g., longitudinal, perpendicular). Embodiments of the invention (in the case of an internal thread) give the closure a soft feel because the fingers are first in contact with the smooth surface of the thread support element and because protrusions for grip are not needed. Because of being able to have a smooth surface in embodiments of the invention, visual elements can be imaged on the thread support element (e.g., advertising, expiration dates). Such visual elements can be read by machines. The visual elements can be imaged on the smooth portion of the thread support element (e.g., printing), but they can also be imprinted indelibly by changing the shape of the individual recesses accordingly. When the individual recesses of the embodiments of the invention are windows, these windows allow a smooth passage of gas. This is particularly interesting for containers that are under pressure (eg carbonated liquids). When the individual recesses of the embodiment of the invention are numerous large windows (in the case of an internal thread), the mechanism of action of the threaded closure is visible, which makes the design attractive and increases the distinction and recognisability of a product.
    Embodiments of closures of the invention can be used in a separate container, but can also be integrated into other systems such as for example in engines or machines, in catering systems, engineer systems, health care systems, agricultural systems, and in any other system where a closure with thread is required.
    The upper wall is a portion at the end of the closure, and is connected to the thread support member. It is preferably circular, and it acts as an occluding surface when pressed against a container opening. The upper wall is configured to lockably cooperate with the opening of an object such as a container. In the closed state, the upper wall is configured to close the opening, preferably to hermetically close, to prevent the passage of material into or out of the container. Furthermore, it can offer protection against the environment (protective barrier). The inner side of the upper wall that is pressed against the container opening may comprise additional material that is different from the material of the closure, or additional elements that contribute to achieving a more hermetic closure. A person skilled in the art can understand that the most suitable material dimensions such as wall thickness and shape of the upper end depend on the content and use, and he understands how to appropriately configure this.
    The thread support element extends from the upper wall. The thread support element is effectively connected at one end to the upper wall, and can be open at another end. The support element for screw thread comprises a body which is preferably annular. In particular, the thread support element comprises a body that is hollow and cylindrical. It has an internal surface (see, for example, FIG. 4, FIG. 9, FIG. 12, FIG. 14, and FIG. 16; 104 internal surface) and an external surface (see, for example, FIG. 4, FIG. 9, FIG. 12, FIG. 14, and FIG. 16; 106 external surface). The outer surface can be substantially smooth. The outer surface may be provided with one or more protrusions; they can increase the manual grip. The thickness is the thickness of material between the internal and external surface. The internal surface or the external surface can be provided with a screw thread.
    At least one separate recess may be provided on the thread support element. The at least one separate recess may be provided on the internal and / or external surface of the thread support element. The at least one separate recess extends below the internal and / or external surface of the threaded support element. The individual recess can partially extend over the support element for screw thread, in particular over the body thereof. The individual recess can extend completely over the thread support element, the inner surface being connected to the outer surface. Such a separate recess can be called a window. The individual recess can furthermore partially or fully extend over the screw thread.
    By referring to a recess as "separate" it is meant that a recess can be distinguished from the body of the threaded support element or from another separate recess. Where there are several separate recesses, they are spatially separated.
    A separate recess is not merely a protrusion or fold formed by extending or extending around a region of the thread support element or around the individual recess. The term "recess" preferably means that part of the thickness of the thread support element has been effectively removed. The presence of a recess causes a weight reduction of the closure. The weight reduction is compared to when the recess is not present.
    A person skilled in the art can understand that the shape, size and number of the individual recesses can be freely chosen, and he understands how to configure this appropriately. The edges of the individual recess can be rounded to avoid a rough feeling. The end of a separate recess can become smaller in any direction, this can increase or decrease the surface area for grip. In the case of a window, the shrinking of the individual recess can help to create a barrier to prevent the skin from coming into contact with the screw thread. A person skilled in the art can understand that the positioning of the at least one separate recess relative to the underlying thread can influence the degree of retention of the parts, and he understands how to configure this appropriately. A person skilled in the art can understand that providing windows in the thread support element can expose the thread, and understand how to appropriately configure it so that the integrity of the thread is preserved. The at least one separate recess may be limited to the thread support element, but may also extend over a portion of the thread, or may include the entire width of the thread. The at least one separate recess can have an open or closed end, by which is meant that the separate recess does not have to be bound by the respective walls of the threaded support element.
    A separate recess can take any shape, for example, in the shape of a spit (see FIGS. 3-5). The individual recess can take any form of marking (see FIGS. 11-14). The tag can be alphanumeric, graphic, photographic, or any image of a visual element. Such a visual element can avoid the use of ink and is indelible. Such a marking can be read by machines. Such a marking has a high visual contrast, in particular for a separate recess that is a window.
    Preferably there are a large number of individual recesses. They may be evenly distributed on the surface of the thread support element.
    The support element for screw thread is provided with a screw thread. The screw thread is configured to connect to a complementary screw thread, for example on a container, in particular on the neck of the container. The thread of the thread support element can extend to the upper wall. The thread of the thread support element can extend to the open end of the thread support element. The thread may be continuous or interrupted. The screw thread may be provided on an internal surface or on an external surface of the thread support element.
    Because the thread support element is connected to the upper wall, and the thread is provided on the thread support element, there is a transfer of displacement and / or force from the thread to the upper wall via the thread support element.
    When the thread is provided on the inner surface of the threaded support element, the outer surface of the threaded support element can serve as a surface for manipulation, for example for applying manual torsion.
    Where the container neck having an opening is provided with a thread on the external surface, the threaded closure can be a threaded cap which consists of an upper wall with closed end and a cylindrical support element for thread provided with a thread complementary internal thread and extending from the upper wall (see, for example, FIGS. 2-14). Where the container neck is threaded on the internal surface, the threaded closure may be a threaded plug which consists of an upper wall with closed end and a cylindrical support element for thread which is provided with a complementary external thread and which extends from the upper wall (see, for example, FIGS. 15-16).
    A thread is composed of a base that is connected to a surface of the thread support element, an upper portion that is generally, but not necessarily, pointed, and one or more side walls that connect the base to the upper portion and that interact with the complementary thread of the container. This interaction causes displacement, force and friction. An expert understands that the characteristics of the thread (such as, for example, diameter, pitch, and number of revolutions) can affect the displacements and / or turning, the required force, and the degree of stability, and he understands how to handle it appropriately can configure.
    The closure can be made of any suitable material. Preferably, at least partially and preferably entirely, is made of a polymeric material. The polymeric material is preferably formable. The closure can be manufactured by means of a forming technique such as, for example, injection molding.
    The closure is intended to close an opening repeatedly. The term "repeated" closing means that the closing can close and open the opening more than once, preferably several times. By "closing" is meant limiting flow through an opening, and forming a protective barrier. In such a state, content can be stored in a container. When the container is provided with a threaded neck with an opening, the closure may be a threaded closure such as a threaded cap or plug configured to connect to the threaded neck to close the opening. By this action, the upper end of the closure is displaced relative to the neck and the opening thereon and it can hermetically occlude the opening because the rotation causes the upper wall to rise or lower. The main components of a closure are an upper wall, a thread support element and a thread. The upper wall acts as an occluding and protective surface (direct or indirect protective barrier) when pressed onto a container opening. The screw thread of the closure interacts with the screw thread of the container, and can move the upper wall, exerting force and tension on it via the screw support element. The material of the screw thread of the closure, the material of the screw thread of the container, the shape of the screw thread and the length of screw thread determine the degree of retention of a closure on a container. The thread support element transfers forces from the thread to the upper wall. When the thread is provided on an internal surface, the thread support element has an external surface through which the closure can be manipulated. Unlike the upper wall, the threaded support element does not act as a protective barrier to the contents of the container. Because the threaded support element does not act as a protective barrier, the individual recesses do not reduce the functions of the threaded support element. The individual recesses add functions, and offer surfaces for grip through which the closure can be easily manipulated. Because no additional protrusions are required for grip, the weight of the closure is very low. In addition to the aforementioned reduction in mass due to omission of the protrusions for grip, the individual recesses reduce the weight of the closure by reducing the volume of the thread support element. Because there is no need for additional protrusions for grip, the thread support element has a smooth and pleasant surface. In the case of windows on the threaded support element, gas can easily and smoothly escape from the container through the windows of the threaded support element. This can be particularly interesting for containers that are under pressure. Embodiments of closures of the invention allow visual elements to be communicated in various ways. The individual recesses on the threaded support element can be formed so as to depict visual elements, or the smooth surface of the threaded support element can be used to display visual elements (e.g., printing). FIG. 1 is an image of a closure as it is available today. The closure includes an upper wall (102) and a thread support element (108) that has a uniform wall thickness and is threaded. The outer wall of the thread support element (108) is provided with longitudinally placed protrusions for grip (118) that increase the friction.
    FIG. 2, the thread support element (108) of the example of the threaded closure (100) of the invention has longitudinally placed protrusions for grip (118) and numerous individual recesses (112) that are rectangular windows. These individual recesses (112) that are windows reduce the weight of the closure, offer an additional surface for grip, and allow a more direct outflow of gas.
    FIG. 3, the thread support element (108) of the threaded closure (100) of the invention has separate recesses (112) that are rectangular windows positioned in the circumferential direction. FIG. 4 is another view of the threaded closure in FIG. 3. The thread support element (108) allows a transfer of displacement or force from the internal thread (124) to the upper wall (102). The external surface (106) of the thread support element (108) is otherwise smooth, which makes it possible to image visual elements (e.g. printing) on it. In this example, the individual recesses (112) are windows that are primarily provided between the threads (124).
    FIG. 5, the thread support element (108) of the example of the threaded closure (100) of the invention has numerous individual recesses (112) that are longitudinally oriented rectangular windows. Because these individual recesses (112) which are windows are so numerous, the total volume that the thread support element (108) forms is small, so that this closure has a very low weight. Because of the high number of windows, the screw thread (124) and the working mechanism are visible. This gives an attractive design and increases the recognisability of the product on the racks.
    FIG. 6, the thread support element (108) of the example of the threaded closure (100) of the invention 6 has large individual recesses (112) that are rectangular windows. The large empty volume of these individual recesses (112) which are windows give this closure a very low weight. The thread support element (108) is reduced to six columns that connect the thread (124) to the upper wall (102). Because of the large empty volume of these rectangular windows, the screw thread (124) and the working mechanism are visible. This gives an attractive design and increases the recognisability of the product on the racks.
    FIG. 7, the threaded support element (108) of the example of the threaded closure (100) of the invention 6 has large individual recesses (112), they do not pass through the wall of the threaded support element (108). Because these individual recesses (112) have a large void volume, there is a smooth feeling when the closure is manipulated.
    FIG. 8, the threaded support element (108) of the example of the threaded closure (100) of the invention has numerous individual recesses (112) that are square windows. The surface of the thread support element (108) is largely smooth, which makes it possible to display visual elements (e.g., printing). The square shape of the windows create both a longitudinal and transverse surface for grip. FIG. 9 is another view of the threaded closure in FIG. 8. In this example, the individual recesses (112) that are windows extend as far as the thread (124); they only cover the thread support element (108).
    FIG. 10, the thread support element (108) of the example of the threaded closure (100) of the invention has numerous oval-shaped individual recesses (112). These oval-shaped individual recesses (112) allow easy manipulation while retaining the soft feel because they interact appropriately with the pads or tips of the fingers.
    FIG. 11, the thread support element (108) of the example of the threaded closure (100) of the invention has numerous individual recesses (112) in the form of alphanumeric markings. These individual recesses (112) which are windows provide a surface for grip, reduce the weight of the closure, allow a smooth outflow of gas, and depict indelible, highly contrasting, machine-readable visual elements. Despite the presence of these windows, the thread support element (108) is largely smooth, which gives a pleasant feeling when the closure is manipulated. FIG. 12 is another view of the threaded closure in FIG. 11. In this example, the individual recesses (112) that are windows extend as far as the thread (124); they only cover the thread support element (108).
    FIG. 13, the thread support element (108) of the example of the threaded closure (100) of the invention has letter-shaped individual recesses (112). These individual recesses (112) provide a soft surface for grip, reduce the weight of the cap, and depict indelible, highly contrasting, machine-readable visual elements. FIG. 14 is another view of the threaded closure in FIG. The thread (124) provided on the inner surface (104) of the thread support element (108) is not adversely affected by the letter-shaped individual recesses (112).
    FIG. 15, the thread support element (108) of the example of the threaded closure (100) of the invention has numerous separate recesses (112) that are longitudinally arranged rectangular windows. The longitudinal protruding handle (130) allows easy manipulation of the closure. The thread (124) is provided on the external surface (106) of the thread support element (108). FIG. 16 is another view of the threaded closure in FIG. The thread (124) provided on the outer surface (106) of the thread support element (108) is not adversely affected by the individual recesses (112) that are longitudinally placed rectangular windows.
    With the skills of one skilled in the art, the invention may include variations including, but not limited to, number, size, material, shape, color, placement, and placement relative to other components of the invention of all components of the invention including but not limited to the upper wall, the thread support element, the thread and the individual recess.
    Embodiments of the invention may have additional parts or features including but not limited to protrusions for grips, grip handles and longitudinally protruding handles.
    The application of the invention to closures having a thread on the internal or external surface of the thread support element is equivalent.
    The individual recesses can be limited to the thread support element, but can also extend to a part of the thread, or can cover the entire width of the thread.
    The individual recesses can have an open or closed end, which means that the individual recesses do not have to be bound by the respective walls of the threaded support element.
    The term "recess" preferably means that part of the thickness of the thread support element has been effectively removed. It does not mean that a recess is created by extending an area of the thread support element adjacent or around the individual recess.
