    [0001] Integral opening and closing device for cans and cans with oval non-deformability Field of the invention
    [0002] The present invention refers to an integral opening and closing device for cans and cans with non-deformation of the oval, of those that can be used to cover pouring holes in cans and cans that have been opened when a part of their original lid has been torn off to enable the partial emptying of its content and subsequent storage of the rest.
    [0003] Exemplary situations of such needs of
    [0004] closing the hole to store product remains due to partial emptying are mainly due to the progressive consumption of products, such as condensed and sweetened milk, carbonated soft drinks in metal or plastic cans, in terms of the food consumption sector, in addition effervescent, volatile, caustic or corrosive liquids, viscous, etc., in the sector of products for human consumption not necessarily food, such as pharmaceuticals or beauty, but also of products intended for industrial or household cleaning, such as supplies of greasing liquids for vehicle engines or stationary machines, or the care of urban furniture, etc.
    [0005] Specifically, the integral opening and closing device for cans and cans with non-deformation of the oval, object of the invention, can be used to cover pouring holes in cans and cans, and to allow the partial emptying of their contents by pouring, especially in cans. and tins of lids with a circular base.
    [0006] Background of the invention
    [0007] Hitherto only closure devices are known that are used by screw or snap closure with a part spanning the full diameter of the surface side of the opening of a can or can. Generally, use is made of a circular-shaped piece of a semi-soft plastic material whose annular side overlaps externally on the side wall of the can or can, or a screw-on tin lid. This is also usually the solution for a closure, in the case that the opening on the side of the can or can is only partial.
    [0008] Examples of products whose wrapping opens totally or partially on one side of one side as a pouring hole are, first of all, the already mentioned condensed milk or soft drinks in aluminum cans, the first one having at least a lid for its closure, although not In all countries of its commercialization, while in the sector of soft drinks offered in aluminum cans with a partial hole in their lid, a lid that accompanies it since its manufacture is not usually detected. To cover and store product residues in these containers, one has to resort to plastic lids that are generally sold as accessories and not specific for the container whose hole is to be covered. However, there is no universal closure lid that offers a solution for the possibility of covering the partial pouring hole of the lid of the jar or can, which makes it possible to pour the product after opening it and which is an integral part of it and not mere accessory.
    [0009] Therefore there is a need for an integral opening and closing device for cans and cans with non-deformability of the oval, for the possibility of plugging pour holes in them, and for allow the partial emptying of its contents by pouring, especially in cans and cans with round base lids. It is precisely here where the present invention comes into play.
    [0010] Summary of the invention
    [0011] Integral opening and closing device for cans and cans with non-deformability of the oval, to enable the partial emptying of the content and subsequent closure of a container, with an uncapped oval as an integral part of the lid of this container, the oval delimited by a line of weakening in circumference and with a lever for the opening of the oval that is in fixed connection with the cover through riveting or similar known technique, characterized in that the lever comprises a riveting end provided with a starting extension that presents a bend towards the lid while the other end has a hand grip with an upper covering of the oval and an oval that has two connections towards the lid of the container and that presents a non-deformable surface. According to one aspect of the invention, the riveting end comprises a central riveting surface of the same piece, this end and the rest of the body of the lever being in fixed connection with the surface of the lid of the container by riveting.
    [0012] According to another aspect of the invention, the lever comprises between the riveting end and the hand gripper end, opposite the latter in the longitudinal direction, a connection, of the same piece, in the form of two non-deformable lateral bridges in the face of the force exerted when uncovering the oval for presenting longitudinal cladding braces stamped on them, with cross-bend axes at their ends with the hand grip.
    [0013] According to a further aspect of the invention, the lever has a starting extension, made of the same piece, between the two non-deformable lateral bridges with three free sides and the fourth in connection with the end of the hand grip, presenting the opposite side to this in its end a transverse and perpendicular fold towards the line of weakness of the lid of the container.
    [0014] According to yet another aspect of the invention, the lever has a hand gripper end as a connection to the starter extension and the two non-deformable side bridges, made from the same piece, which have a diameter greater than the surface of the oval below it. circling the line of weakness of this.
    [0015] According to a further aspect of the invention, the lever has a bending cross axis on the side of the starter extension with the connection of the end of the hand gripper and the ends of the two lateral bridges with the end of the hand gripper.
    [0016] According to a further aspect of the invention, the end of the hand gripper has a protrusion on the upper surface for gripping the fingers during their vertical movement.
    [0017] According to a further aspect of the invention, the end of the hand gripper has a sealing gasket of semi-soft material on the lower surface with a diameter greater than that of the oval for a hermetic seal.
    [0018] According to yet another aspect of the invention, the oval has a line of weakness surrounding it being in fixed connection with the rest of the lid of the container through two parallel interruptions in this line on the side of the center of the lid with the riveting that They present a lateral axis of bending the oval towards its vertical position.
    [0019] According to a further aspect of the invention, the oval has a central longitudinal brace that guarantees its non-deformability when raised to a vertical position by means of the force exerted by the bending of the starter extension to its lower surface.
    [0021] According to another additional aspect of the invention, the fold towards the lid is non-deformable by a longitudinal brace of the fold sectioning with its edge of the fold the line of weakness of the oval located between the two parallel interruptions because it presents a width less than the distance between the interruptions. and by the transversal angle with respect to the body of the lever towards the lid of the container.

    [0057] Detailed description of the invention
    [0058] The description that follows will be made in relation to the use of the integral opening and closing device for cans and cans with non-deformability of the oval (1), object of the invention, for food containers.
    [0059] However, this should not be construed as a limitation of the invention, but as an illustration thereof by way of example, since, as mentioned above, the present device may have many other applications.
    [0060] Referring firstly to Figures 1 to 6 of the drawings, it is noted that the integral opening and closing device for cans and cans with non-deformability of the oval (1), object of the invention, comprises a lever (6) that has one end provided with a starter extension (8) that has a fold (9) towards the cover (4) while the other end is provided with a hand grip (10) with an upper covering of the oval (11) and an oval (3) that has two connections towards the lid (4) of the container (2) and that has a non-deformable surface.
    [0061] Figure 1 shows an integral opening and closing device for cans and cans (1), the device is visible in a new state, the lever (6) with the end of the hand grip (10), with the connection in the form of two Non-deformable side bridges (14) and with the central riveting surface (12) on the upper surface of the lid (4) of the container (2), riveted to the lid of the container, and the oval (3) to be uncovered.
    [0062] Figure 2 shows a plan view of a lever (6) as a loose piece seen from above, visible the axes of transverse bending (16) of the non-deformable lateral bridges (14).
    [0063] Figure 3 shows an upward view of the lever (6), appreciating the downward fold (9) split from the same piece, the protrusion (17) on the upper surface and the sealing gasket (18) on the surface bottom of the end of the hand gripper (10).
    [0064] Figure 4 is a perspective view of a lid (4) of a container (2) with the lever (6) removed, the line of weakness (5) surrounding the oval (3) with the two parallel interruptions (19) can be seen and the location of the rivet (7).
    [0065] Figure 5 shows a cross-sectional view of a container (2) with a lid (4), seen in elevation with the oval (3) detached and raised by the bend (9) of the lever (6).
    [0066] Figure 6 shows a perspective view of an oval (3) as a loose piece seen from below, the central longitudinal brace (21) can be seen.
    [0067] To use said integral opening and closing device for cans and cans with non-deformability of the oval (1) for the first time, the part provided in the lid (4) of the container (2) is uncovered by manual start with the end of the hand grip (10) of the lever (6) by grasping the protrusion (17) on the upper surface with the fingers of one hand then pulling upwards. The fold (9) cuts with its edge of the fold (23) the part provided in the line of weakness (5) that surrounds the oval (3) between the two parallel interruptions (19). When the lifting angle of the lever (6) equals the angle that the bend (9) presents with respect to the body of the lever, the inner face of this makes contact with the central longitudinal brace (21) in the lower part of the oval ( 3). The progressive opening of the angle towards 180 ° with respect to the initial position raises the oval (3), detaching it previously from the line of weakness due to the non-deformability of both the central longitudinal brace (21) of the oval and the longitudinal brace of the fold (22 ) by the lateral fold axis of the oval (20) and the transversal fold axes (16) at the ends of the non-deformable lateral bridges (14) with the hand grip.
    [0069] This is followed by an inclination to pour the container (2). In this way, the contents of the container can be evacuated in the desired quantity. Once the pouring maneuver is finished, the hole in the lid (4) is closed by redirecting the lever (6) together with the oval (3) that is under the end of the hand gripper (10) towards its initial position . The sealing gasket (18) remains in union with the cover (4) sealing with the lower surface of the hand grip (10) the gap caused between the detached oval and the cover (4) by the breakage of the line of weakness (5) during the opening action due to the larger diameter of the hand grip compared to that of the oval and the characteristics of the semi-soft material of the gasket. The container (2) is hermetically closed.
    [0071] For future evacuations, in a first step the hand grip (10) is pulled upwards and it is closed as in the previous description, pushing it to a horizontal position in the opposite direction to the previous one.
    [0073] The integral opening and closing device for cans and cans with non-deformation of the oval (1), thus allows the desired or necessary openings and closings until the container (2) is completely emptied.
    [0075] Obviously, the use of the integral opening and closing device for cans and cans with non-deformation of the oval (1), object of the invention, for purposes other than its use for the contents of food products would be developed in the same way as previously described, pulling of the hand grip (10) up or down to open or close, preceding the actuation of the bend (9) of the start extension (8) of the lever (6) to uncover the oval (3) on the cover ( 4) through movement from a horizontal to a vertical position for the use of the opening and closing device in a container (2) before being used for the first time.
    [0077] The invention has thus created an integral opening and closing device for cans and cans with non-deformability of the oval that offers several advantages, among which the following can be highlighted:
    [0078] - Simple structure, and as a consequence, ease of use.
    [0080] Practical use, due to the universality and versatility of application.
    [0082] - Form of aesthetic presentation, since both waiting to be used for the first time and later when storing remains of the unconsumed content, the sliding opening and closing device offers an appearance of integrity.
    [0083] The above description has focused on the essential features of the invention. However, it is understood that the device described could be subject to modifications in its shape and structure without departing from the invention. Therefore, the scope of this is intended to be limited only by the content of the appended claims.
