    Pouring cap for liquids
    The present invention refers to a pouring plug for liquids.
    In particular, the present invention refers to a pouring stopper for liquids, of the type that has a body fixedly attachable to the neck of a container intended to contain the liquid, as well as an articulated upper cap, presenting the body
    10 a liquid passageway can be connected to the neck of the container and the cap is a protrusion of a conjugate shape, which fits with said duct when the cap is in the closed position.
    The publication of the Spanish Patent ES2255883 discloses a pouring plug of this type.
    Currently, according to Royal Decree 895/2013, of November 15, certain marketing measures are established in the olive oil and olive pomace oil sector, which establishes that in establishments in the sector of the
    20 catering and catering and catering services, oils will be made available to the final consumer in labeled containers and provided with an opening system that loses its integrity after its first use.
    In order to achieve inviolable caps and thus comply with the regulations explained above, one of the possibilities is to make a part of the cap tear-off.
    To facilitate tearing, reducing the force necessary for the user to tear a part of the cap easily, it is made of a material with a small tear resistance. However, the use of materials with a resistance to
    30 small tear can lead to stiffness and stability problems in the cap.
    Spanish patent publications ES1066671U and ES1064802U disclose two-piece caps. A problem with these caps is that both the outer part of the cap and the inner part of the cap are attached to the neck of the container 35 by clipping. This means that the container neck has to have two projections, which implies that the container neck has to be of special construction. The piece


    The interior has two characteristics that are a priori incompatible: on the one hand the plastic has to be rigid enough to withstand the joint with the neck of the container and on the other hand it has to have a small tear resistance to allow an easy tear in its central part . The incompatibility of the two previous features makes it normally difficult to tear the tear away part of the inner part by the user. In addition, the union between the central projection and the passage of liquids is joined by interference throughout its entire contact area, hindering the proper functioning throughout its useful life due to the deterioration of said union.
    The outer piece also usually has a double hinge type "butterfly" that articulates the cap of the cap. The hinge, however, requires a tear and / or tear resistant material, which is again incompatible with the material requirements that entail the existence of a tear-off membrane.
    Clipping is understood as a union of different pieces with shape interference. In said union, the interference of form does not act during the union of the pieces, but when trying to separate them.
    It is an objective of the present invention to disclose a plug with a clipping fixation system that does not present the problems of violability of the known caps, as well as the problems of stiffness of the different parts due to the use of different properties of the materials and joints between their different pieces.
    To provide a solution to the problems raised, the present invention discloses a pouring stopper for liquids, of the type made of plastic material, which has a body with coupling means outside the neck of a container, the plug defining a conduit of liquid passage equipped with a tear-off membrane that obstructs the conduit of the liquid passage, as well as an articulated upper cap that has a central projection that fits into said liquid outlet conduit when the cap is in the closed position, the pouring plug constituted of, at least a first and a second piece, characterized in that the first piece or outer piece is a piece comprising said means of coupling to the outside of the neck of a container, the second piece or inner piece being arranged in the inside of the outer piece, having the second piece of the said tear-off membrane, and leaving the first and the gunda piece fixed to each other by means of union.


    In a possible preferred embodiment, said connecting means that fix the inner part and the outer part comprise a conjugate protrusion and flange that prevent the relative movement of the pieces in the direction corresponding to the exit of the liquid from the container.
    5The connection between the inner and the outer part can be done by means of a projection withinterference and a flange that prevents vertical movement between the inner and outer piece(in the direction of the outflow of the inner liquid flow), joining the neck of the containerOnly with the outer part by means of a clipping. This feature allows the use
    10 of materials with different properties between the inner and outer part of the cap. Alternatively, the inner part may be of a more appropriate material to have a tear-off membrane. Preferably, a plastic material with a lower yield strength can be visualized for the inner part.
    In the present invention the elastic limit refers to the definition and measurement modes indicated in the international standard ISO 527: 2012.
    More preferably, the material of the inner piece will have an elastic limit at least 15% lower than the material of the outer piece. Even more preferably, the material of the inner piece will have an elastic limit at least 20% lower than the outer piece material.
    The inner part has a lower tear resistance, since it does not have to be attached to the neck of the container and thus it can be easier to tear its central part by means of the tearing ring 25. Tear resistance is measured according to ISO 8067: 2008.
    Preferably the inner part has a circumferential elbow around the base of the liquid passageway forming 90 ° between them, and preferably said circumferential elbow has a circumferential flange in a lower plane parallel to the elbow
    30 circumferential, said circumferential flange being the main means of connection between the inner piece and the outer piece.
    Preferably, the inner part comprises auxiliary coupling means by interference to the inner part of the neck of the container as well as to the central projection of the outer part 35.


    Preferably the outer part and the inner part of the cap are made of plastic materials with different properties.
    Preferably the material of the inner part has a tear strength less than 5 of the outer piece.
    Preferably the inner part comprises a part of the lowered liquid passageway coinciding with the area of articulation of the cap.
    10 Preferably, the inner part lacks elements for joining by clipping with the neck of the container.
    Preferably the outer part comprises a tear-off seal between the cap and the lower part of the outer piece.
    Preferably, the outer part comprises a hood for articulating the hood on the inner face of the outer piece.
    Preferably the outer piece has all its rounded edges.
    In short, the present invention is based on an optimal distribution of the elements of the cap into different pieces, which allows to optimize the properties of the materials of each one. Thus, an outer piece or piece will be responsible for fixing the neck, while another inner piece, called the inner piece, will contain the tear-off membrane
    25 that clogs the passage of liquids, usually called a spout. Said piece may lack any connection to the neck, and in particular to the outside of the neck. In order to maintain the integrity of the plug, a joint between both pieces must be provided.
    For a better understanding of the invention, some drawings of an embodiment of the present invention are attached by way of explanatory but not limiting example.
    Figure 1 is a perspective view of a possible embodiment of the pouring stopper for liquids of the present invention.
    Figure 2 is a plan view of the embodiment of Figure 1.5.


    Figure 3 is a perspective view of the inner part of the object of the present invention.
    Figure 4 is a cross-sectional view of the embodiment of Figure 1.
    Figure 5 is a detailed view of the section of Figure 4.
    Figure 6 is a cross-sectional view of the embodiment of Figure 1, with the cap in the open position.
    Figure 1 shows the outer part -1 of a pouring plug according to the present invention that is intended to be used in oil containers, which defines a shape with all its rounded edges which makes it more ergonomic. The outer part of the cap -1-is attached to the neck of the container -100-by clipping. The cap has a cap -14-joined by a tear-off seal -143-to the bottom -13-of the cap -1-. This tear joint seal -143-is torn by pulling the hooks -142-and -141-from the tear joint seal. The cap -14-has a slot -16-to facilitate opening and closing.
    Figure 2 shows the plan view of the outer part of the cap -1-, where you can see the cap -14-as well as observe the two hooks -141-and -142-of the tear-off seal located at 60º to each other.
    Figure 3 shows an inner part -2-of the cap, usable together with the outer part -1-. This piece is located between the neck of the container -100- and the outer part -1 of the cap, as can be seen in figure 4. At the base of the said inner part -2-of the cap, the outer face is observed of the area of radial elements -24- for the regularization of the flow. In the upper part of the liquid passage duct -25- there is an upper edge -251-. From the bottom of the liquid passageway -25-a wall is projected outwardly perpendicularly, surrounding the liquid passageway -25- with a circumferential elbow -26-at 90 °. The skirt joins the aforementioned circumferential elbow -26- with the circumferential flange -261- in a parallel plane at a different level from said wall in the direction of the container neck. As can be seen in Figure 5, the conjugate joint of said circumferential flange -26- with the projection -136- of the outer part is coupled by dimensional interference, the main joining means being between the inner part -3- and the piece exterior -1-. The said liquid passage duct -25-presents in the


    articulation area of the hood, the passage of liquids reduced -27-. Finally, the liquid passage duct -25- has in its central part the tearing ring -22-.
    Figure 4 shows a section of the pouring plug. In general it is formed by two different bodies joined by different means to each other and to the neck of the container -100-: the outer part -1-of the cap and the inner part -2-of the cap.
    The outer part -1-of the cap, is fixed to the neck of the container -100-by different means: the bottom -13-of the outer piece of the cap rests on top of the wall -101 and the projection -102-of the neck -100 -of the container, in turn has an anti-return clipping -132-and a protrusion -131-that by crossing the wallet -103-neck of the container prevents the cap from being released. The wall -103-is connected to the projection -131-by means of auxiliary coupling means by dimensional interference.
    The central cap -14-contains a central protrusion -19-inwards that fits with the liquid passageway -25-. The cap -14-incorporates a butterfly-shaped joint -17-, which allows it to be opened, after tearing the seal -143-with a tear-off joint.
    Once the cap -14- is opened, it is possible to pull the tear ring -22- in order to tear the tear-off membrane -21- by the circumferential precut -219- (of smaller thickness). From this moment it is possible to pour the liquid contained in the container, which passes through the area of radial elements for flow regularization -23-.
    Figure 5 shows a detail of Figure 4 in which it is possible to observe the fixing of the different parts of the neck -100-of the container with the outer part -1-of the cap and the inner part -2-of the cap.
    The inner part -2-of the plug is mainly joined to the outer part -1-by the projection -136-perimeter that combines with the circumferential flange -261-, this is the main union between the two pieces of the plug and consists of a union by interference that causes a pressure towards the outside of the inner part towards the outer piece, which prevents the vertical movement in the direction of exit of the liquid contained inside the container. The inner part -2-is auxiliaryly seated at the upper end of the neck of the container -100-which in turn is also fixed to the inside of the neck of the container -100-by


    Dimensional interference by the projection -241-of the outer face -24-and the central projection -19-is fixed to the inner part of the plug -2-by interference by the projection -191 with the projection -252-. The projection -241- is intended to ensure the tightness of the plug.
    5 Figure 6 shows the embodiment of the previous figures in an open position, after removing the tear-off joint -143-. It shows the operation of the double butterfly-shaped hinge -17-. The rest of the element has already been described, so they will not be explained in depth again.
    10 The cap can be made using two different compounds for each of the pieces. For example, an LDPE (Low Density Polyethylene) could be used for the inner part while an LLPDE (Linear Low Density Polyethylene) could be used for the outer part, which are compatible materials with similar properties, but
    15 presenting the LLPDE an elastic limit of the order of 15-30% higher than the LPDE.
