Description

DESCRIPTION

Recyclable cap for containers and container that incorporates it

The present invention refers to a recyclable stopper for containers for perfumery, cosmetics and the like. More particularly, it refers to a cap of the external protection lid or cap type that is coupled to these containers through the outlet area of the product contained inside, in particular through the area that has a metal collar, by adjusting to pressure.

The present invention also refers to the container for perfumery, cosmetics and the like that includes the recyclable plug of the invention attached, particularly in the area with the metal collar.

Background of the invention

As is known, many perfumery and cosmetic products are frequently associated, for marketing purposes, with another product, in particular a sample product, which serves as an advertising medium. Both the sample products and the originals use caps of the external protection lid or cap type that must transmit the elegance and quality of the product contained in the container.

In the state of the art, there may be a variety of caps for perfume bottles or bottles, normally made of glass, intended to contain perfumery, cosmetic and similar products.

However, most of said external protection caps are made of thermoplastic material whose coupling to the container has the function of avoiding scratches and consequent association with loss of quality of the product contained inside. There are also external protection caps made of materials with little or no deformation such as wood, metal, or glass, which include a plastic insert, sealed, fixed or integral with the cap. In these cases, the insert is difficult, if not impossible, to separate from the stopper once the product contained in the container has been used up, which makes recycling this type of stopper extremely difficult.

In addition, on many occasions these containers are not refillable, so they still generate a greater volume of waste that is difficult to recycle because they are basically not reusable.

Therefore, it is desirable to provide a stopper for containers for perfumery, cosmetics and the like that is fully recyclable.

In the state of the art, there is a wide variety of caps that include plastic inserts in their interior cavity to prevent scratches on the metal collar of the container after continuous use, normally daily and on more than one occasion, since scratches they reduce the perception of elegance and quality of the product contained within, such as, for example, a perfume.

Therefore, it is also desirable to provide a stopper for perfumery, cosmetic and similar containers that also fits the container in a safe and reliable manner for the user and that its continued use does not result in inadvertent detachment of the stopper, normally due to deformations and/or or widening of the plug and, consequently, loss of pressure in the adjustment by coupling.

Thus, there is a need to provide a lid or cap-type stopper for perfumery, cosmetics and similar containers that is recyclable, that also does not scratch the container, in particular the collar of the container in its continued use, which is also safe and reliable. for the user, without involuntary detachments. Especially for couplings of two metal parts, it is also desirable to provide the user with a good feeling in use.

It is desirable to provide a stopper with additional manufacturing advantage, one that can be manufactured at high speed or in high volumes and with high reproducibility across stoppers.

The present invention provides a stopper of the external protection lid or cap type that overcomes the problems of the state of the art, also providing other advantages that will be described below.
