Description

A kind of lipstick with sealing structure

Technical field

The utility model relates to the mouths with sealing structure good to a kind of lipstick more particularly to a kind of protective performance It is red.

Background technique

Lipstick obtains modern female and is especially as a kind of cosmetic, easy to use and imparting people's aesthetic feeling and gloss The favor of young woman, Lipstick structure in a tubular form, nut cap and pedestal including grafting, when frequency of use is higher or improper use When, be easy to loosen between Lipstick cover and pedestal or abrasion, lid and pedestal gap caused to increase, air-tightness decline, dust and Dirt is easily accessible lipstick inner cavity, pollutes lipstick lotion, and not only lipstick lotion is easy dry rotten, also brings danger to user Evil.

Utility model content

The utility model mainly solves the technical issues of bad existing lipstick leakproofness, poor air-tightness；It provides a kind of anti- Protect the good lipstick with sealing structure of performance.

In order to solve above-mentioned technical problem, the utility model is mainly adopted the following technical solutions:

A kind of lipstick with sealing structure of the utility model, including pedestal, be embedded in pedestal and accommodate lipstick cream The coil component of body and the nut cap being sheathed on pedestal, the outer surface on the pedestal top is equipped with external screw thread, described externally threaded Bottom is arranged with rubber seal, and the nut cap inner cavity is equipped with the internal screw thread matched with the external screw thread, and nut cap passes through above-mentioned Internal and external threads cooperation is tightened on pedestal, and the conventional connected structure of lipstick is improved to threaded connection and rubber seal, so that Sealing performance between lipstick nut cap and pedestal gets a promotion, and eliminates conventional connection there are gaps that larger, lipstick inner cavity is easy The phenomenon that being contaminated.

Preferably, the pedestal is in variable-diameter structure, including upper section and lower section, upper diameter is less than lower section diameter, upper section With the junction platform annular in shape of lower section, the external screw thread is set to upper section outer surface, and upper section bottom is equipped with horizontal convex annular It rises, forms groove between the annular protrusion and above-mentioned annular platform, the rubber seal is embedded in the groove, outside It is arranged rubber seal between screw thread and base platform, horizontal annular protrusion is set on pedestal and is embedded rubber seal Circle, enables nut cap uniformly to squeeze rubber seal when screwing, sealing effect is more preferable.

Preferably, the nut cap inner cavity is equipped with inner chamfer, the outer diameter of the inner chamfer is outer with the rubber seal Diameter matches, the inclined-plane of inner chamfer against and compress rubber seal, by the bevel structure of inner chamfer, when so that nut cap screwing Rubber seal can be gradually squeezed, achievees the effect that elastic packing, air-tightness is made to be improved.

Preferably, the nut cap material is transparent plastic, the behaviour in service of observation lipstick lotion can be convenient.

The beneficial effects of the utility model are: the conventional connected structure of lipstick is improved to threaded connection and rubber seal Circle, and by the way that horizontal annular protrusion and nut cap inner chamfer structure are arranged on pedestal, so that between lipstick nut cap and pedestal Sealing performance be highly improved, eliminate conventional connection there are gaps the phenomenon that larger, lipstick inner cavity is easily contaminated, Reach preferable elastic packing effect.

Detailed description of the invention

Fig. 3 is the pipe cap interior cavity section figure in Fig. 1 structure.

1. pedestal in figure, 11. external screw threads, 12. annular platforms, 13. annular protrusions, 2. lipstick lotions, 3. coil components, 4. Nut cap, 41. internal screw threads, 42. inner chamfers, 5. rubber seal.

Specific embodiment

Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.

Embodiment: a kind of lipstick with sealing structure of the present embodiment as depicted in figs. 1 and 2, including pedestal 1, is embedded In in pedestal and accommodating the coil component 3 of lipstick lotion 2 and the nut cap 4 that is sheathed on pedestal, pedestal is in variable-diameter structure, including upper Section and lower section, upper diameter are less than lower section diameter, the junction of upper section and lower section platform 12 annular in shape, and upper section designs on outer surface There is external screw thread 11, is equipped with horizontal annular protrusion 13, annular protrusion and above-mentioned ring-shaped flat in the external screw thread lower end of upper section bottom Groove is formed between platform, rubber seal 5 is embedded in groove, and nut cap is made of transparent plastic, as shown in figure 3, in nut cap Chamber design has the internal screw thread 41 matched with external screw thread, and nut cap is tightened on pedestal by the cooperation of above-mentioned internal and external threads, nut cap Open end be also devised with inner chamfer 42, the outer diameter of inner chamfer matches with the outer diameter of rubber seal, and the inclined-plane of inner chamfer supports It leans on and compresses rubber seal.

In use, unscrewing and removing nut cap, the lipstick lotion coil component on rotating base makes lipstick lotion from coil group It screws out and rises in part, using finishing, reversely rotate lipstick lotion coil component, lipstick lotion declines and bounces back, then will lid Cap alignment inserted base simultaneously screws, and nut cap inner cavity internal screw thread and pedestal external screw thread are cooperatively connected at this time, continues to screw, nut cap is lasting Decline make the inclined-plane of nut cap inner chamfer slowly against and squeeze rubber seal, the elastic packing for completing entire nut cap and pedestal connects It connects.

In the description of the present invention, technical term "upper", "lower", "front", "rear", "left", "right", " vertical ", " cross ", "inner", "outside" etc. indicate direction or positional relationship is direction based on the figure or positional relationship, are merely for convenience of describing With understand the technical solution of the utility model, described above not to limit the utility model, the utility model is also not only It is limited to above explained citing, the change that those skilled in the art are made in the essential scope of the utility model Change, retrofit, increase or replace, is regarded as the protection scope of the utility model.
