Sealed package for cosmetics

Abstract

The invention provides a sealed package (1) for cosmetics. A longitudinal axis (1a) and a normal plane, which is perpendicular to the longitudinal axis, are defined, and the sealed package comprises a first accommodating main body (2), a second accommodating main body (3) and a central body (4); the central body comprises a basal part (40) and a smearing device (42); the first accommodating main body can be connected to the second accommodating main body (3); a sealed structure and an opened structure of the package (1) are defined, and internal capacity (10) of the package is defined by the sealed structure; the central body is restrained and partially arranged in the second accommodating main body, and the central body is also partially arranged in the first accommodating main body when the package is represented as the sealed structure; the first accommodating main body and the second accommodating main body comprise a fastening device (6) by which the first accommodating main body and the second accommodating main body are connected; the package comprises a sealing device; the sealing device comprises a sealing piece (50) and a supporting basal part (51) which are oppositely arranged in the sealed structure in a mode of being adjacent, so that air tightness of the package is guaranteed; and the sealing device (5) is separated from the fastening device (6) and is separated 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
