Description
Technical Field
The utility model relates to a cosmetics packaging thing field, concretely relates to prevent press key lid against current.
Background
The cosmetic is a chemical industrial product or a fine chemical product which is applied to any part of the surface of a human body, such as skin, hair, nails, lips and teeth, by smearing, spraying or the like, so as to achieve the purposes of cleaning, maintaining, beautifying, decorating and changing the appearance, or correcting the odor of the human body and keeping a good state.
Generally, cream cosmetics are stored in a bottle with a button head. When the cosmetic bottle is used, the milky cosmetic is pumped out of the bottle body by pressing the key, and then a user can apply the cosmetic to a designated area. Because part of the pumped cosmetics can remain in the pipeline of the spray head, the cosmetics can flow back into the bottle body, and the cosmetics in the bottle can be polluted.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present invention is directed to anti-reflux key covers.
kinds of prevent button lid against current, including the lid, the lid front end is provided with the nozzle, the lid inboard is provided with the button chamber, lid inboard middle part is provided with the guide chamber, the guide chamber is linked together with the nozzle, cowl between nozzle and the guide chamber, cowl are located the downside inner wall of nozzle, the highest point in guide chamber is higher than the highest point of nozzle inner wall, guide chamber top still is provided with the guide post.
Preferably, the outer wall of the guide cavity is provided with a plurality of convex ribs.
Preferably, the outer wall of the nozzle is of a conical structure, and the inner wall of the nozzle is of a cylindrical cavity structure.
Preferably, the top of the cover body is provided with an arc-shaped pressing area.
The utility model has the advantages that the reasonable design is adopted, the highest position of the guide cavity is higher than the highest position of the inner wall of the nozzle, pumped cosmetics can flow into the nozzle along the guide cavity, and meanwhile, under the action of the arc-shaped baffle, the cosmetics flowing into the nozzle can not flow back to the guide cavity along the inner wall of the nozzle, so that the backflow phenomenon is effectively reduced; simultaneously set up the guide post in leading the chamber, the guide post can effectively guide the cosmetics that pump was pumped to flow into in the nozzle.

Detailed Description
The invention is described in further detail with reference to the figures and the embodiments.
As shown in FIGS. 1-4, specific embodiment be kinds of prevent keypad covers against current, including lid 1, lid 1 front end is provided with nozzle 2, 1 inboard of lid is provided with button chamber 7, 1 inboard middle part of lid is provided with guide chamber 4, guide chamber 4 is linked together with nozzle 2, cowl 3 between nozzle 2 and the guide chamber 4, cowl 3 is located the downside inner wall of nozzle 2, the highest point in guide chamber 4 is higher than the highest point of 2 inner walls of nozzle, guide chamber 4 top still is provided with guide post 5. cowl's height is less than half of the internal diameter of nozzle.
In order to better fix the cover body, a plurality of convex ribs 6 are arranged on the outer wall of the guide cavity 4. The stability is better when lid and bottle combination.
For better pumping out the cosmetics, the outer wall of the nozzle 2 is in a conical structure, and the inner wall of the nozzle 2 is in a cylindrical cavity structure. The cylindrical cavity structure can reduce resistance and facilitate pumping out of cosmetics; the tapered outer wall reduces the amount of cosmetic left over.
In order to facilitate pressing, the top of the cover body 1 is provided with an arc-shaped pressing area 2.
The cosmetic backflow prevention device has the advantages that the reasonable design is adopted, the highest position of the guide cavity is higher than the highest position of the inner wall of the nozzle, pumped cosmetics can flow into the nozzle along the guide cavity, meanwhile, under the action of the arc-shaped baffle, the cosmetics flowing into the nozzle cannot flow back to the guide cavity along the inner wall of the nozzle, and the backflow phenomenon is effectively reduced; simultaneously set up the guide post in leading the chamber, the guide post can effectively guide the cosmetics that pump was pumped to flow into in the nozzle.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
Claims (4)
- The backflow-preventing key cover is characterized in that an arc-shaped baffle is arranged between the nozzle and the guide cavity and positioned on the inner wall of the lower side of the nozzle, the highest position of the guide cavity is higher than the highest position of the inner wall of the nozzle, and a guide column is further arranged at the top of the guide cavity.
- 2. The anti-reflux keycap of claim 1, wherein: the outer wall of the guide cavity is provided with a plurality of convex ribs.
