Description

DESCRIPTION

DETACHABLE PLUG

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to a removable cap that provides, to the intended function, advantages and characteristics, which are described in detail below.

The object of the present invention falls on a stopper for those intended to close glass jars and similar containers, which are those that include an external lid or metal trim, usually made of aluminum, and an internal plastic insert with fixing means by pressure to the neck of the bottle, it is distinguished by the fact that it is easily removable in order to allow the separation of the pieces of different material that make up said stopper once its useful life has ended in order to recycle them properly and thus contribute to the protection of the environment.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture of caps for containers, focusing particularly on the field of bi-material caps, in particular those externally metallic with internal plastic insert, suitable for snap closure of jars especially of cosmetic products and other similar glass containers.

BACKGROUND OF THE INVENTION

Currently, most of the externally metallic stoppers that are usually used to close bottles of cosmetic products and the like, are made up of at least two different pieces:

- an external part, which is what is called a trim, because it is the one that is left in sight and is made with the most aesthetically pleasing materials, so they are often metallic, for example, aluminum and

- an inner part, which is called an insert, which is usually made of a more flexible and economical material, usually plastic, in which the closure means of the stopper are implemented for its adjustment to the neck of the bottle.

The problem with this type of stopper is that, when its useful life is over, in order to properly recycle the parts that make it up, it is necessary to separate them, otherwise the stopper will end up rejecting waste and cannot be recycled. The fact is that, since normally both pieces are very well glued together so that during the use of the plug they do not separate, it is difficult for users to take the trouble to use tools to separate them, since, in addition to investing time in it, Often enough force is required and there is a risk of injury from breaking one or both parts of the plug.

The objective of the present invention is, therefore, to solve this problem by developing a new type of stopper in which, once its useful life is over, to cover and uncover as many times as necessary the bottle to which it is intended without the parties that form it separate from each other, be easily removable to separate said pieces without having to use any type of tool and without requiring a lot of physical force to do so, so that the user does not have any difficulty in carrying out said separation and, consequently, can proceed to deposit each part of the plug in the recycling container and these, in turn, can be conveniently recycled in the corresponding plant.

On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of any other removable cap of the type that concerns here that has the same or similar technical and structural characteristics is unknown. those presented by the one claimed here.

EXPLANATION OF THE INVENTION

The removable plug that the invention proposes is configured as the ideal solution to the aforementioned objective, the characterizing details being that make it possible and that distinguish it conveniently included in the final claims that accompany the present description.

Specifically, what the invention proposes, as previously stated, is a stopper intended for the closure of glass jars and similar containers that, comprising a lid or external part that we will call a beautifier and that is made of a metallic material, for example made of aluminum, and an interior piece or insert of another different material, preferably plastic, and in which the means for attaching the stopper by pressure to the neck of the bottle are contemplated, it is distinguished by the fact that it is easily removable in order to allow the separation of the pieces of different material that make up said cap so that, once their useful life is over, they can be recycled appropriately by separately and thereby contribute to the protection of the environment.

For this, and more specifically, the cap of the invention is distinguished, essentially, by comprising fastening means between parts that are easily removable, without the use of tools of any kind, to allow their separation.

Specifically, the stopper is essentially distinguished in that it also comprises an intermediate part or closure base configured to fit between the trim and the insert, which comprises at least one opening in which a flange provided in the insert fits, at the same while the trim also has a flange at its lower end, all of which is configured in such a way that, when said base and the insert are located inside the trim, the insert flange passes through the opening of the closure base and rests on the flange of the bezel, preventing the insert from separating from the bezel when the user pulls up on said bezel to remove the neck cap from the bottle.

And, on the other hand, only when the user pulls down the closure base, in which a wing has been provided for this purpose, allows the insert to separate from the trim, since with it the upper part of said opening On the base, it pushes the tab of the insert in, releasing it from its lock with the trim flange.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the numbering adopted, an exemplary non-limiting embodiment of the removable cap of the invention can be seen, which includes what is described in detail below.

Thus, as seen in said figures, the cap of the invention is a pressure-closing cap (1) of which it comprises, at least:

- an external piece or trim (2), formed by a hollow cylindrical body and closed at its upper base of a first material, preferably metallic; and

- an internal part or insert (3), formed by a cylindrical body that is coupled to the interior of the trim (2) and which is of a second material different from the material of the trim (2), for example, of plastic, and in the that means for fixing (4) to the bottle (6) to which said stopper (1) is intended are contemplated.

And, from said known configuration, the cap (1) is essentially distinguished in that it also comprises an intermediate part or closure base (9) that is configured to fit between the trim (2) and the insert (3) and comprises at least one opening (12). Furthermore, the insert (3) comprises at least one flange (7) that emerges progressively separating from the external surface of the insert (3) towards the outside and, for its part, the trim (2) comprises a flange (8) at the lower end of said bezel (2), in such a way that when the closing base (9) and the insert (3) are located inside the bezel (2) and the flange (7) of the insert (3) passes through the opening (12) of the closure base (9) and rests on the flange (8) of the trim (2), on the one hand, prevents the insert (3) from separating from the trim (2) when the user pulls upwards said bezel (2) to remove the neck cap (10) from the bottle (6), and on the other side allows the insert (3) to separate from the bezel (2) when the user pulls down the base of closing (9) by pushing the upper part of said opening (12) inwards the tab (7) of the insert (3) releasing it from its locking with the flange (8) of the trim (2).

Preferably, the insert (3) comprises two flanges (7) arranged at diametrically opposite points on its surface in coincidence with two openings (12) of the closure base (9).

Furthermore, to facilitate said operation of separating the insert (3) from the bezel (2) by pulling down on the closure base (9), said closure base (9) preferably comprises a perimeter wing (11) that slightly protrudes below the trim (2) when the closing base (9) and the insert (3) are coupled to the trim (2), allowing force to be applied to said perimeter wing (11).

Preferably, the closure base (9) is of the same material as the trim (2), that is, preferably of metallic material.

Figures 1 to 8 show how, in the preferred embodiment, the insert (3) of the cap (1) of the invention has two flanges (7) arranged at diametrically opposite points of its cylindrical surface in coincidence with two openings ( 12) of the closing base (9), which is preferably annular. For its part, the flange (8) of the trim (2) covers the entire contour thereof.

Finally, and without being a limitation, the fixing means (4) that the stopper (1) has for its fixing to the bottle (6) for which it is intended, for example, consist of indentations made in the surface of the insert (3) that press on an additional piece (13) that covers the neck (10) of the bottle (6) which, in turn, in the example shown is one that has a spray pump (14) to dose the contained product.

Once the nature of the present invention has been described, as well as the way to put it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the matter understands its scope and the advantages derived from it.
