Description

A kind of vacuum powder box chamber air can discharged

Technical field

This utility model relates to the device of cosmetic package, a kind of vacuum that can be discharged by chamber air Powder box.

Background technology

At present, the vacuum powder box for cosmetic package that market is sold, major part is during assembling, in inner chamber Air cannot be completely exhausted out so that coordinates imprecision and assembling not in place between inner chamber parts, forms open gap, thus cause Product defects maybe cannot use.It follows that do not have the vacuum powder box of vent design, product is generally widely used, the most especially New intention, and there is use defect.

Summary of the invention

This utility model provides one to be discharged by chamber air for solving technical problem present in known technology Vacuum powder box.

This utility model is adopted the technical scheme that by solving technical problem present in known technology: one can be by The vacuum powder box that chamber air is discharged, including upper cover, inner chamber parts, fixed support and base, described inner chamber parts and described solid Fixed rack is assemblied in described base, and described inner chamber parts are affixed with described fixed support, and described upper cover is buckled on described base, Described inner chamber parts include pump core, chamber lid and the cavity set gradually from top to bottom, are provided with piston in described cavity, described Chamber lid uses with described cavity threadeds.

This utility model has the advantage that with good effect: the structure threadeded with cavity by employing chamber lid, Air in cavity can be discharged during assembling, and then can be prevented effectively from because in cavity, gas cannot be discharged and caused Assemble not in place or poorly sealed defect；Chamber lid uses screw connection structure with cavity simultaneously, it is simple to assembling, is conducive to improving The stability of product function, product structure optimization, production, packaging technology are succinctly, particularly suitable to vacuum powder box series products, product Using method and other like product there is no difference, it is possible in protecting box, cosmetics will not seepage in time depositing, transport, be inverted With solid.In sum, this utility model avoids the assembling defect of vacuum powder box series products, improves the qualified of assembling product Rate.
