Definitions
- Screw cap for containers and a container provided with said cap
- the object of this application is the registration of a screw-closure cap for containers, as well as a container provided with said cap.
- the invention proposes the development of a cap provided with an upper cap and a lower ring fixed to each other, in such a way that they do not separate during the screwing and/or unscrewing of the cap on a container neck intended for packaging carbonated drinks, Non-carbonated or mineralized water.
- closure caps made from plastic material have been used for many years, which are provided with an internal thread that can be screwed into a thread shaped in the neck of the container itself, allowing the contents inside the container to be kept sealed, for example, in the case of a bottle of the type used for bottling beverages, such as mineral water, soft drinks, or the like.
- Closing caps for containers are known in the prior art, in particular intended for containers that have an opening in a neck provided with a threaded outer portion, comprising a lower ring configured to be coupleable to the neck of the container and an upper cap that has a its inner face has a thread configured to be coupleable to the outer threaded portion of a container neck.
- the upper plug and the lower ring are articulated with each other by means of a hinged portion, such that the upper plug can ascend through the threaded portion of the neck while the lower ring remains in its original position in order not to separate the system. closure of the container with respect to the container itself.
- An example of this type of stopper is described in documents ES 1247151 and ES 1237189.
- Similar caps are also known where the lower ring is made up of two rings located one above the other, so that the incorporation of this type of cap in the containers does not allow reducing the height of the neck, and consequently, reducing the amount of material intended for the manufacture of packaging, an aspect that is currently desired in this sector, for environmental purposes.
- this height can also be negatively affected by the arrangement of the breaking points that act as tamper-evident seals, which further favor a greater height of the lower ring.
- the present invention has been developed in order to provide a closure cap that is configured as a novelty within the field of application and solves the aforementioned drawbacks, also providing other additional advantages that will be evident from the description that follows. accompany below.
- the invention is characterized by the fact that the union between the upper plug and the lower ring is carried out by means of two extensions with a certain degree of flexibility that are diametrically opposed to each other, each of them made from a thickening present in the lower ring that includes a grooved portion such that the extensions are formed above the grooved portion, in such a way that the two extensions have the same outer diameter as the outer diameter of the thickening, presenting the lower rim of the body of the upper plug a step that defines a recessed portion in which the extensions are located, such that in a closed condition both extensions are arranged above and parallel to the body of the lower ring, while in an open position of the closing plug, the The upper end of the extensions acts as a hinge region such that the plug is rotatable.
- the plug can have great freedom of movement and can easily move up the threaded portion of the neck during unscrewing, without suffering resistance in the opposite direction.
- the lateral extensions remain far from the external thread of the neck of the container, providing great freedom of movement to the cap, without any type of tension, facilitating the positioning action by the user. and centering of the cap on the mouth of the container, necessary for the proper screwing of the cap during the closing action of the container.
- linear openings present in the lower ring are provided which run parallel to the lower rim of said lower ring and the linear openings being radially arranged and at least partially subjacent with respect to the grooved portion and spaced apart from each other.
- the presence of these linear openings provides an additional degree of flexibility during the unscrewing and screwing phases of the closing cap, being particularly suitable for necks or necks of containers (for example, bottles) with higher thread sections, in which only the ability to move the slotted portions is not enough to achieve freedom of movement, so it is evident that the use of the closing plug is facilitated for the user.
- closing cap of the invention does not cause problems (such as friction with the side walls of the channels through which the caps circulate) in the cap feeding lines during their automated placement on the neck of containers in bottling plants, since parts of the stopper of the diameter defined by the upper stopper and lower ring do not protrude excessively.
- this design allows the flexion zone of the extensions to be at a higher height than the flexion zone that is created when a horizontal cut is made in the lower ring, therefore the unscrewing path that the cap must take is lower and the user requires less handling time.
- stop means are provided intended to hold the top plug fixedly in an inverted position with respect to the disposition adopted by the top plug during the closed position.
- the stop means can comprise a projection that projects from the lower ring, which is aligned in height with a tab that protrudes laterally from the lower rim of the upper plug, in such a way that, in an open condition, the tab abuts a upper surface of the projection, in which the flange has a curved trajectory adaptable to the radius of curvature of the lower ring.
- the interior of the lower ring may include retaining means intended to act on a pehmetral projection present in a neck of a container, such retaining means being present partially along the inner diameter of the body of the lower ring.
- the retaining means comprise a plurality of protrusions aligned and equidistant from one another, which run parallel to the lower rim of the upper plug.
- the closing plug of the invention can include an tamper-evident seal between the upper plug and the lower ring.
- the tamper-evident seal is made up of a plurality of breaking points distributed in a gap existing between the lower edge of the upper stopper and the upper edge of the lower ring.
- the closure plug is made of a single piece of injection-mouldable or compression-mouldable plastic material. This plug can leave the molding area completely finished, so it does not require a subsequent process, which reduces manufacturing time and costs.
- the closing cap described represents, therefore, an innovative structure with structural and constituent characteristics unknown up to now for the purpose for which it is intended, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested. .
- Figure 1.- Is a perspective view of a first embodiment of the closing cap according to the present invention.
- Figure 2.- Is a side elevational view of the closing cap represented in figure 1;
- Figure 4.- Is a perspective view from below of the screw closure cap represented in figure 1;
- Figure 6. It is a sequential view that shows different phases of the opening operation of the closure cap in a container
- Figure 7.- Is a perspective view of a second embodiment of the screw-on closure cap according to the present invention.
- Figure 8.- Is a perspective view of the closure cap represented in figure 7 placed on the neck of a container.
- the screw cap for containers is intended for containers that have an opening in a neck (100) provided with a threaded outer portion.
- Said stopper is formed by a lower ring (1) configured to be coupleable to the neck of the container and an upper stopper (2) that has a thread (21) on its inner face configured to be coupleable to the external threaded portion presenting a neck of container (100), the upper cap (2) and the lower ring (1) being joined together in such a way that they can rotate integrally with each other around the neck of the container.
- This closing plug is made of a single piece of moldable plastic material by injection or compression molding. Mention that the container neck can have a lower height through the use of the closure cap that is described below.
- An outer surface of the lateral face defined by the body of the upper plug (2) presents a non-smooth surface (22), in particular, a knurled surface formed by a plurality of ribs in a radial distribution that extend from the upper part to the lower part of the upper plug body (2).
- the union between the upper cap (2) and the lower ring (1) is carried out by means of two extensions (3) with a certain degree of flexibility and constant cross section, which are diametrically opposed to each other, each one of them formed from of a thickening (11) present in the lower ring that includes a grooved portion (7) such that the extensions are shaped above the grooved portion (7), in such a way that the two extensions (3) have the same outer diameter than the outer diameter of the thickening, presenting the lower edge of the body of the upper plug (2) a step (20) that defines a recessed portion in which the extensions (3) are located, in such a way that in an open position of the plug closing, the upper end of the extensions (3) acts as a hinge region in such a way that the upper plug (2) is capable of turning.
- the stopper includes stop means designed to keep the upper stopper (2) in a fixed manner in an inverted position with respect to the arrangement adopted by the upper stopper (2) during the closed position.
- these stop means comprise a projection (4) that protrudes from the lower ring (1), which is aligned in height with a tab (5) that protrudes laterally from the lower edge of the upper cap (2), in such a way that , in an open condition (figure 8), the flange abuts a lower surface of the projection (4). Mention that the flange (5) has a surface with a curved trajectory adaptable to the radius of curvature of the lower ring.
- a pair of linear openings (9) present in the lower ring (1) are provided, which run parallel to the lower rim of said lower ring (1) and the linear openings (9) being arranged radially and partially subjacent with respect to the portion slotted (7) and spaced apart. As can be seen, such linear openings (9) are located on each side of the projection (4).
- the interior of the lower ring (1) includes retention means (described below) that are intended to act on a perimeter projection present in the neck of a container, said retention means being present along the internal diameter of the body of the container. bottom ring (1).
- retention means comprise a plurality of protrusions (8) aligned and equidistant from each other, which run parallel to the lower edge of the upper cap (2).
- the closure cap includes an tamper-evident seal located between the upper cap (2) and the lower ring (1).
- This seal is made up of a plurality of break points (6) spaced and equidistant from each other located between the lower part of the upper plug (2) and the upper edge of the lower ring (1).
- each of the linear openings includes second tamper-evident seals consisting of break bridges (10) located between the upper and lower edge of said openings.
- Figures 7 and 8 show a second embodiment of the closing plug, whose common parts have the same numerical references, in which the linear openings (9') are located on the lower edge of the lower ring (1), so that in such a way that they are internally open unlike the embodiment described above.
- the linear openings (9') are devoid of second tamper-evident seals as they are internally open, that is, free of material from the lower ring.
