Roller-type dual cosmetic case having airless pump

Abstract

The present invention relates a roller-type dual cosmetic case having an airless pump, and more particularly, to a roller-type dual cosmetic case having an airless pump wherein a so-called roller-type cosmetic case, which enables the cosmetics stored in a cosmetic case to be applied on the skin using a rolling-operated roller, is formed into a case body of a dual structure and an airless pump is provided, so that a foreign material or air is basically prevented from being introduced from the outside during the non-use of the cosmetics and the contents of the cosmetic case is thus prevented from being contaminated and deteriorated and the cosmetics are discharged in a constant amount all the time by operating the pump during the use of the cosmetics, thereby enabling the contents to be used more conveniently and efficiently.The roller-type dual cosmetic case comprises a tube-type inner case 10 made of a flexible material so as to store contents of a cream type and having a fixing element 11 at its upper part, the fixing element having a rigid discharge pipe 12 for discharging the contents; a rigid outer case 20 protecting the inner case 10 and maintaining an overall external shape of the cosmetic case, the inner case and the outer case forming a case of a dual structure; a head 30 engaged at an upper part of the outer case 20 and having therein a flow passage through which the contents are discharged and at its upper part a nozzle 33 and a mount space 31; a roller 40 horizontally provided to an upper part of the head, structured to be idling and enabling the contents discharged through the nozzle 33 to be applied to the skin; and an airless pump 50 that is connected at its one side to the discharge pipe 12 of the inner case 10 and at its other side to the nozzle 33 in the mount space 31 of the head 30 and enables the contents stored in the inner case 10 to be discharged to the nozzle 33 with pumping force caused by a horizontal push operation of an operation button mounted to be exposed at one side of the head.

AI Technical Summary

Benefits of technology

[0015]An object of the invention is to improve a structure of a roller-type dual cosmetic case, i.e., to form a storage case of the roller-type cosmetic case into a dual structure and to mount a separate airless pimp to an opening of the cosmetic case, thereby providing a roller-type dual cosmetic case having an airless pump enabling cosmetics of a liquid state as well as cosmetics of a cream state to be conveniently and safely stored and used.

[0016]Another object of the invention is to provide a roller-type dual cosmetic case having an airless pump capable of blocking the external air and foreign substance from being introduced into the cosmetic case to prevent the contents therein from being evaporated or contaminated and deteriorated and discharging the contents in a proper amount when using the cosmetics to conveniently use the contents.

Problems solved by technology

As the external shape of the tube is gradually distorted as the used amount, the original shape cannot be kept, so that the external appearance becomes poorer.

In other words, the structure quality and the product quality are remarkably deteriorated.

Furthermore, due to the deformed external shape, the preservation ability is lowered and it is not easy to handle the product.

Furthermore, since the contents are discharged by the compression, it is difficult to discharge the contents in a necessary fixed amount.

However, it is difficult to discharge the contents in a proper amount, which can be used at one time.

However, the compression force is not always constant, so that the more or less contents are discharged.

Thus, it is not convenient to use it and the unnecessary waste is caused.

Further, although the opening of the storage case is air-tightly contacted to the surface of the roller, a separate closing means is not provided.

Hence, the exterior air is introduced or the moisture included in the contents are evaporated through the opening during the non-use of the cosmetics, thereby deteriorating the function of the contents and contaminating and spoiling the contents.
