Description

DESCRIPTION

COMPOSITE CAP

OBJECT OF THE INVENTION

The invention, as expressed in the wording of the present specification, refers to a composite cap that contributes, to the function to which it is intended, advantages and characteristics, which are described in detail below, which suppose an improvement of the current state of the technique.

The object of the present invention resides, in particular, in a composite cap, that is to say, of those formed from, at least, an external part and an internal part, normally of different material, for example metal, external and plastic. internal, which presents a series of structural improvements to ensure the correct alignment and fixation between both parts.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of plugs, focusing particularly on the scope of the plugs comprising at least two pieces; an internal part and an external part, coupled together.

BACKGROUND OF THE INVENTION

As is known, in the market there are innumerable types and models of plugs for different uses and containers. Among them, it is common, for example in the field of cosmetics and perfumes, the existence of composite plugs from at least two pieces that fit together, where one is located internally and can not be seen, being made of some simpler material and easier to obtain by mold to give it the necessary configuration that includes the thread or other means of closure, for example plastic, and the other one that is located externally, housing inside the internal part, and is more aesthetic material, for example metal.

Well, the problem that the present invention aims to solve is that which occurs when the configuration of one piece and another causes that there are gaps between them and their can produce unwanted couplings or movements of displacement that disfigure the product or damage a correct operation of the product. stopper, may even get to make the inner piece out of its place outside the outer piece, for which the development of an improved structural configuration of the inner piece is provided that provides the same means to avoid said problem and ensure the best alignment and fixation between both pieces.

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 plug that presents technical and structural characteristics equal or similar to those presented here is unknown. it is claimed.

EXPLANATION OF THE INVENTION

The composite plug proposed by the invention is configured as the solution suited to the aforementioned objective, the details that make it possible and distinguish it conveniently set out in the final claims that accompany the present description.

More specifically, what the invention proposes, as has been pointed out previously, it is a composite plug, specifically composed of, at least, an external part and an internal part, normally of different material, for example metal, external and plastic internal, whose structural configuration is specially designed to ensure the correct alignment and fixation between both pieces.

In particular, it comprises at least one deformable and elastic element in its internal upper part that tends to push the internal part downwards, forcing to adopt the correct position thereof, which is that in which said internal piece remains in contact with the flange lower part of the external part, and therefore, eliminating the existence of "dance" or unwanted displacements between one piece and another that may cause misalignment of the axial center between the two parts caused by the slack in the fit between the two parts.

And, on the other hand, said lower flange of the external part defines an internal projection in which the lower edge of the internal part abuts, preventing said internal part from being able to leave its housing inside the external part by said part. bottom of it.

Furthermore, preferably, said lower flange projecting internally from the external part, is determined by a section turned towards the inside of the wall of the external part that rises internally in a section and on which a step provided on the face fits into the face. external edge of the inner part.

In any case, preferably, said deformable and elastic elements is incorporated in the upper part of the internal part and, preferably, has a curved shape that allows the deformation thereof to endow it with a "spring" effect.

Preferably, the deformable and elastic element of the upper part is defined by an externally curvilinear fin that extends vertically in the inner part's diameter

Said deformable and elastic element, furthermore, can be made of the same material as the internal part itself, preferably forming an integral part thereof, normally when it is made of plastic, or it can be made with a different material, for example, a foam or similar.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part of the same, some plans in which, with an illustrative and non-limiting character, It has represented the following:

Figure 3 shows an enlarged view of detail B, indicated in Figure 1, which allows to see the configuration of the lower edge of the external part that ensures the hold of the inner part.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, and in accordance with the numeration adopted, one can observe in them an example of non-limitative realization of the proposed composite plug, which comprises what is described in detail below.

Thus, as seen in said figures, the plug (1) in question is one that is configured from, at least, an external part (2) and an internal part (3), usually of different material, incorporated in the central hollow that defines the external part (2) adjusting to the shape and dimensions thereof with greater or less clearance, counting the internal part (3), in its hollow interior, with means of coupling (4) to the container to which the plug (1) is intended, and is distinguished by the fact that it comprises at least one deformable and elastic element (5) in its internal upper part, between both pieces (2, 3) that tends to push the piece internally (3) downwards, forcing it into contact with the lower flange of the external part (2), which, in turn, defines an internal projection (6) in which the lower edge (7) of the internal part (3), avoiding displacements between one piece and another and the misalignment between both of the axial axis (e) and preventing the internal part (3) leave its housing inside the external part (2) by said lower part.

Preferably, said deformable and elastic element (5) is incorporated in the upper part of the internal part (3) and, preferably, has a curved shape that allows the deformation thereof to endow it with a "spring" effect.

Preferably, the deformable and elastic element (5) of the upper part is defined by one or more externally curvilinear fins (5a) that are they extend vertically in the perimeter of the internal part (3), it can be made of the same material as the internal part (3), preferably forming an integral part thereof, or made with a different material, preferably foam.

Preferably, the internal projection (6) of the lower edge of the external part (2) is determined by a section turned towards the interior of the wall of said external part (2) that rises internally in a section (6a) on which a step (7a) provided for this purpose fits on the external face of the lower edge (7) of the internal part (3).

Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field understands its scope and the advantages derived therefrom.
