Definitions

  • the invention proposes the development of a biodegradable cap for containers, which has an embellishing casing and an additional element made of cork that acts as a sealing medium, taking advantage of its natural properties.
  • containers especially those dedicated to containing cosmetic products, such as, for example, emulsions, whose aesthetic appearance is of great importance, in which the cap that closes them must be in accordance with the design of the product itself. container, and have the ability to provide a guarantee of adequate closure to the product it contains.
  • cork is characterized by being a porous material and impervious to liquids like most gases, for its great resistance to humidity, and for ensuring a perfect closure, making these qualities suitable as a stopper. for bottles of wine or the like.
  • caps used in cosmetic containers are made of plastic, which implies that once used it becomes a waste that is not always recycled, so from an environmental point of view it is harmful, having more relevance the large volume of cosmetic packaging that is sold annually.
  • the wooden covers use an inner part made of plastic material that is fixed by a gasket that also acts as a sealing element. For this reason, a high precision fit is required between the lid and the container to ensure the tightness of the assembly. Wood cannot be used for the same purpose as plastic due to the expansions that wood can undergo depending on the humidity and temperature conditions.
  • the fastening means comprise a pair of projections diametrically opposed to each other, which project laterally out of the sealing element, which can be engaged in corresponding slotted portions made in a side wall of the trim casing.
  • the fact of having two projections makes it possible to release tension between the sealing element and the container where the cap is mounted.
  • the coupling means consist of a thread portion present on an inner face of the sealing element.
  • the coupling means may also consist of at least one flange projecting perimetrically inward of the sealing element defining a housing with suitable dimensions configured to house a projecting region present in the opening of the container.
