Hermetic packaging for cosmetics

Abstract

The invention provides a sealed package (1) for cosmetics, which defines a longitudinal axis (1a) and a normal plane perpendicular thereto, and comprises first and second containing bodies (2, 3) and a central body (4), the The central body comprises a base (40) and an applicator (42); the first containment body can be coupled to the second containment body (3), defining a closed configuration of the package (1) and an open configuration, the closed configuration defining the package The internal volume (10); the central body is constrained and partially disposed within the second containment body, and is also partially disposed within the first containment body when the package is in a closed configuration, the first and second containment The body includes fastening means (6) adapted to couple the two, the package includes sealing means comprising a seal (50) and a support base (51) arranged adjacent and opposite in the closed configuration to secure the package Airtight, the sealing means (5) are separated from the fastening means (6) and spaced apart from the longitudinal axis (1a).

Description

technical field [0001] The present invention relates to a sealed package for cosmetics. [0002] In particular, the present invention relates to devices for containing and preferably applying cosmetic products. This product could be mascara, rouge, lip gloss, lip balm, liquid eyeliner, eyeliner, eye shadow, makeup, foundation, concealer, serum, cream, skin care product, eye cream, or skin care product. Background technique [0003] Packaging for cosmetic products in liquid or cream state (cream) is known to consist of a container containing the product and a cap capable of being engaged with the container in a closed configuration by means of pressure closure. [0004] In particular, a creamy or liquid cosmetic product has a container consisting of a base body on which the cosmetic product is placed and a housing defining a housing for the base body and the cosmetic product. Furthermore, the known housings can, for example, include kinematics for removing and applying the ...

Problems solved by technology

[0007] In fact, the known packaging does not ensure a tight closure of the containment chamber and thus does not prevent the product contained therein from deteriorating, for example due to oxidation or drying out

[0008] In addition, the non-tightness of the containers usually used for cosmetics becomes worse in use, because the opening and closing of the container shell causes local plastic deformation, which although small, leads to wear of the parts and thus leads to the loss of the product The tightness of the

[0009] As a result of the above, another disadvantage described is that unpreserved cosmetic products are thrown away before they are used up, thus determining increased costs and increased waste

[0010] Finally, another disadvantage is that the containers known in the prior art, in order to avoid this tightness problem, include closure means which are either complicated or require considerable effort to unfasten, which is not always convenient for the user

[0011] One example of a closure mechanism that includes a threaded member requires the user to have to use more time to open the package than a typical tight fit (interference) style, and also causes the user to apply a torque action to the closure mechanism, which may Causes strain on the subbase of the thread itself, resulting in loss of airtightness or damage to the closure mechanism

[0012] On the other hand, tight-fit closures may require more effort to open due to the need to overcome the obstacles posed by the tight fit itself
