Description

DESCRIPTION

Cap for container with easy opening and retention of the lid once opened

The present invention relates to a stopper for containers that are easy to open and retain the lid, once opened.

For the closure of liquid containers, plugs of which at least one part is unscrewed from the mouth and plugs that provide that their lid can be removed to open and/or close the mouth through a simple rotation around a face can generally be provided. joint that forms part of the stopper.

In the first case, caps of which at least a part is unscrewed from the mouth, provide a lid connected to a ring that is arranged in one piece on the threaded mouth of the container. To access and use the liquid placed within the container, the cap must be removed by unscrewing the cap from the threaded mouth of the container. The cap and the ring are held together by frangible bridge-type elements and the cap provides, inside, a complementary thread to that of the mouth.

By acting on the lid by unscrewing it from the mouth, the bridge-like elements break and the lid separates permanently from the ring on the container.

The main drawback is that once the cap is removed it can be dispersed into the environment and this violates anti-pollution laws for plastic materials. Furthermore, if the lid is to be replaced on the mouth of the container, great care must be taken not to drop it or, nevertheless, bring it into contact with materials or products that represent a source of contamination of the liquid contained in the container.

In the second case, caps that provide that their lid can be withdrawn during the opening and/or closing of the mouth of the container by means of a simple rotation around a joint that forms part of the cap, must provide a joint between the lid and the ring. fixing to the container. This articulation is arranged at the height of the container opening, that is to say, at the level of a pouring area if present, which is at the maximum upper height of access to the container. This closed arrangement between the lid, the joint and the outlet opening for the liquid limits the access space to the mouth of the container, when drinking, to a minimum. In fact, a small hinge is provided between the lid and the ring, which, also in an open position between the parts, keeps them very close to each other, preventing access by a user who wishes to drink. The cap may even come into contact with the user's mouth or chin or face in general. All this causes a significant obstacle to the use of this type of container.

If a user wishes to drink from the container, they would be hampered by the presence of the cap rotated for opening. Furthermore, the presence of the lid so close to the outlet opening of the container creates a hindrance that is annoying even in the case of a different use, for example, in the case of transferring part of the liquid contained in the container. Thus, this type of arrangement simply solves the problem of the requirement for no gap between the ring (integral with the container) and the lid (with the container's resettable closure), but does not solve problems of misuse and misuse. easy and inconvenient for the user.

Document US 6474491 refers to a plug or lid for containers according to claim 1.

Documents US 2012/024815, KR 100880006, JP 2014031202 and WO2014/200165 refer to a stopper for containers having a base ring and stopper and thread extensions.

The general objective of the present invention is to provide a stopper for containers capable of solving the aforementioned drawbacks of the known art in an extremely simple, economical and particularly functional way.

A further objective of the present invention is to provide a cap for containers of the type of screw coupling with the container that allows it to be opened and allows easy access to the mouth of the container, once the lid has been removed from it, without However, without being completely separated by a union ring to the container.

A further objective of the present invention is to provide a stopper for containers, which is particularly compact in a sealed and closed position and with a lid that does not impede access to the mouth of the container once removed from it, without completely separating from the lid. same.

Another object of the present invention is to provide a stopper for containers that can be produced by molding plastic material.

The aforementioned objects are achieved by a stopper for containers produced according to independent claim 1 and the following dependent claims.

The structural and functional characteristics of the present invention and its advantages with respect to the technique known will become even more apparent from the following description, with reference to the attached schematic drawings.

figure 13 shows a section of the stopper as it is placed open in figure 12 on the mouth of the container. Referring to Figures 1-7, there is shown an exemplary embodiment, not forming part of the invention, of an easy open cap for containers, with lid retention, once opened.

This type of stopper, indicated as a whole with 11, essentially comprises a base ring 12, to prevent its separation from a bottle or container mouth 13, and a lid 14 to open and close the bottle or container mouth 13. As As can be seen, this stopper 11 can be made in one piece by molding plastic material.

The cap 14, which has an essentially cylindrical inverted cup shape, has an upper closure wall 15 and a side wall 16 fitted internally with threads 17 suitable to engage the threads 19 provided externally with respect to the bottle neck 13.

Cap 14, at its bottom, provides an area in which a hinge arrangement 18 is obtained and placed, allowing for a stable variously hinged connection between base ring 12 and plug cap 14. Hinge arrangement 18 also generally allows lid 14 to be brought from its closed position, aligned and integral with base ring 12 (FIG. 1) to a rotated open position with respect to base ring 12 (FIG. 7) in the embodiment as an example of Figures 1-7. Furthermore, it can also be seen how the lid 14 can remain stably rotated in this open position thanks to its specific features. The base ring 12 also has an essentially cylindrical shape and is produced in various parts.

A first part 20 of the base ring 12 is arranged at one end of the stopper for its full cylindrical extension and is suitable for positioning under an annular projection 21 formed to extend radially externally with respect to the bottle neck 13. Internally, this first part 20 of the base ring 12 provides an annular engaging lip 22 which is directed upwards towards the lid 14 and abuts under the annular projection 21. This provision is such that it prevents the plug from slipping out of the bottle mouth 13, once the stopper 11 is hooked therein.

A second part 23 of the base ring 12 is separated by a circumferential notch 24 from the plug cap 14 and the ends of the wire extensions 26 are connected to it, as described below.

This circumferential notch 24 extends along the entire outer surface of the plug except for the area in which the hinge arrangement 18 is. Opposite ends 25 of an area of the cap 14 in which the hinge arrangement 18 is formed in fact, they are connected to the second part 23 of the base ring 12 by a respective extension of wire 26.

These thread extensions 26 ensure that the cap 14, even once unscrewed from the bottle neck 13, always remains attached to the bottle neck 13 and does not separate from the base ring 12.

Consequently, it can be stated that the base ring 12 comprises a first part 20, which is arranged at one end of the plug for its full cylindrical extension suitable to abut firmly on a mouth of a container, and a second part 23 separated by said circumferential notch 24 of the lid 14 of the stopper to which the ends of the thread extensions 26 are connected.

It should also be noted that the second part 23 of the base ring 12 extends only for a part of the cylindrical extension of the plug integral with the first part 20, while the missing part can be said to be composed of the two thread extensions 26 and by a connecting rod 28 which will be discussed further below.

Therefore, it can be seen that a second notch 33 is defined between the two wire extensions 26 and the connecting rod 28 of the second part of the base ring 12 on one side and the first part 20 of the base ring 12 on the other. other side.

This particular provision of parts to form said second notch 33 is clearly illustrated in figure 6 in the position of lifting the cap 14 from the bottle mouth 13 by unscrewing.

Figure 7 then shows how the hinge arrangement 18 allows the cap 14 to be rotated 180° and beyond with respect to the closed position, once the cap 14 has been completely unscrewed from the bottle neck 13. Thus In this way, a stable opening position is obtained so that the lid 14 does not disturb a user who wishes to have access to the contents of the container, for example, by bringing the mouth of the container or bottle 13 to his mouth.

In particular, the various figures clearly show how the hinge arrangement 18 provides a pair of bridge-like elements 27, which are foldable and which form the stable connection between the cover 14 and said connecting rod 28.

This connecting rod 28 is in turn connected at its ends to the ends 25 of each of the wire extensions 26 extending from the second part 23 of the base ring 12.

It can be seen that the aforementioned opposite ends 25 of cap 14 are defined with opposite ends of connecting rod 28.

It can also be seen in particular from Figures 3 and 4 and Figure 6b, how the hinge arrangement 18 provides a tooth 29 forming part of the outwardly extending cover 14. Above the connecting rod 28, on the other hand, a hole or housing 30 is provided for the aforementioned tooth 29.

This feature of the hinge arrangement 18 causes the lid 14 in the exemplary embodiment to be arranged in a fully open and stable position, as shown in Figure 7. This positioning occurs, once the lid 14 is closed. has been completely unscrewed from the bottle neck 13, when the cap 14 is rotated with respect to the base ring 12 around the hinge arrangement 18 and the tooth 29 is stably pressed-in, for example, in the hole or housing 30 formed above the connecting rod 28 that provides stable positioning means of the lid 14 open and rotated at least 180° with respect to the base ring 12.

Figures 1 and 2 show the stopper of the exemplary embodiment when it has never been used and is arranged in an opening of a container closing the same.

In this position, the cap must also indicate like all caps of this type that the content of the container is the original content filled by the packer thereof.

Thus, the frangible bridge-like elements 31 can be seen, arranged within the circumferential notch 24 of the plug between the cover 14 and the second part 23 of the base ring 12.

An additional frangible bridge-like element 32 is also arranged between the connecting rod 28 of the pair of wire extensions 26 and the first part 20 of the base ring 12, which maintains the hinge arrangement 18 in its initial position of the figures. 3 and 4.

Said frangible bridge-like elements 31 and 32 break when the cap 14 is unscrewed from the bottle neck 13 to open the cap and gain access to the contents of the container.

Figures 8 to 13 show a stopper according to the invention in which the same elements are indicated with the same reference numbers.

Therefore, the component parts need not be described as they are the same.

Furthermore, it should be noted that in the cap 111 according to the invention, a prong 36 is formed above the cap 14 in correspondence with its edge adjacent to the upper closure wall 15 in a recess 35, which protrudes upwards from the cap according to an axis parallel to that of the plug.

Figures 8, 10 and 11 show the stopper of the present invention when it has never been used and is arranged in an opening of a container closing the same.

Also in this example, the articulation arrangement 18 and the thread extensions 26 allow the lid 14 of the present invention to be brought, unscrewed from the mouth, up to a fully and stable open position, as shown in figures 12 and 13. Once the cap 14 has been completely unscrewed from the bottle neck 13, in fact, the cap 14 can be made to rotate with respect to the base ring 12 around the hinge arrangement 18. This rotation causes the protruding tooth 36 to upwards of the cover 14 is inserted into a V-shaped seat, formed in the first part 20 of the base ring 12 and facing upwards, locking the cover 14 in this position (figures 12 and 13).

Also in this case, therefore, stable cap positioning means 14 are created, opened and rotated more than 180° with respect to the base ring 12, also ensuring that the removed cap is not dispersed in the environment. atmosphere.

Therefore, it has been seen and understood that a cap for a container of the type of screw coupling with the container of the present invention allows its wide opening and allows easy access to the mouth of the container in which it is placed.

It has also been seen that according to the present invention, with this type of stopper, once the cover has been removed from the mouth of the container, the cover does not separate from the fixing ring with respect to the container.

Furthermore, according to the present invention, the stopper for containers is particularly compact in a sealed and closed position and with a lid that never impedes access to the mouth of the container, once removed from it, without completely separating from it.

It should also be considered that this type of stopper is extremely simple and convenient to produce, since it can be produced by molding plastic material in one piece.

Therefore, the object mentioned in the preamble of the description has been achieved.

The scope of protection of the present invention is defined by the appended claims.
