Description

Technical Field

[0001] The invention relates to a pump head of a makeup remover pump, which is a one-button opening type makeup remover pump head. Background Art

[0002] The makeup remover pump is one type of lotion pump, generally consisting of a pump head and a bottle body. It is a container for liquid cream cosmetics. By pressing the nozzle of the lotion pump, the liquid cream cosmetics lotion flows out of the container. Its working principle is: by pressing the head cap of the nozzle, the volume of the bottle body increases and decreases periodically, increasing the pressure of the liquid, thereby sucking and discharging the liquid in the bottle. Some existing makeup remover pumps have a disc structure protruding forward on the top, and the liquid flows out from the liquid outlet in the middle of the disc by pressing the disc, such as the application number 201720902071.X disclosed in the Chinese patent literature, the authorization announcement date 2018.05.08, and the utility model name "a pump head mechanism and a makeup remover product container for pressing and discharging liquid"; another example is the application number 201821078467.8 disclosed in the Chinese patent literature, the authorization announcement date 2019.03.26, and the utility model name "a makeup remover pump structure"; and the application number 202120484978.5 disclosed in the Chinese patent literature, the authorization announcement date 2021.012.24, and the utility model name "a makeup remover water pressing bottle pump head". However, the flip cover and bottle cap of the above-mentioned products and similar products are integrally formed, but the button structure design is missing on one side of the bottle cap, resulting in poor safety before use of similar products, and easy accidental discharge of liquid through vibration and other means. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a one-button-opening makeup remover pump head in the art, so as to solve the technical problems that the bottle cap structure with a flip cover in existing similar products lacks a button design, the button structure is relatively simple, the use and assembly are relatively inconvenient, the product as a whole is difficult to recycle, and the environmental protection is poor. The purpose is achieved through the following technical solution.

[0004] A one-key opening makeup remover pump head. An internal thread ring is provided at the bottom of the bottle cap of the makeup remover pump head. A pump port ring is provided inside the internal thread ring of the bottle cap. The pump port buckle of the pump body is fixed to the pump port ring of the bottle cap. The valve stem extending out of the pump body is snap-fitted with the rod sleeve at the bottom of the pressure plate head cap. An anti-detachment plug is provided at the orifice on the top of the pressure plate head cap. The liquid flows out through the orifice at the anti-detachment plug on the top of the pressure plate head cap. The pump core assembly includes a pump body, a valve stem, a plastic ball bead, an inner plug, a piston, a valve needle and a spring. The key point of the structural design is that convex buckling edges are symmetrically provided at both sides of the top of the bottle cap. A button is provided in the button groove on one side of the bottle cap between the buckling edges. The buckling edge of the bottle cap is buckled with the edge of the cover opening corresponding to the flip cover. A flip cover hinged and fixed to the bottle cap is provided on the other side of the bottle cap. An elastic strip is provided between the flip cover and the bottle cap at the hinge. Both ends of the elastic strip are integrally injection-molded with the bottle cap and the flip cover of the bottle cap respectively. The elastic hole of the button passes through the outer diameter of the internal thread ring at the bottom of the bottle cap and at the same time one end is sleeved into the button groove extending out of one side of the bottle cap. The elastic head at the other end of the button extends out of the opening groove on the symmetrically opposite side of the bottle cap of the button groove. The elastic head of the button is aligned with the elastic strip. The elastic hole of the button is larger than the outer diameter of the internal thread ring of the bottle cap. The elastic head of the button abuts against the elastic strip of the bottle cap, and the flip cover of the bottle cap pops up and opens. Thus, when the button is pressed, while the button deforms or displaces, the elastic head at one end of the button abuts against the elastic strip between the flip cover and the bottle cap, and the buckling position between the flip cover and the bottle cap is stressed and displaced or detached, and the flip cover can pop out and open from the bottle cap.

[0005] On both sides of the opening groove at the hinged and fixed part of the flip cover of the bottle cap are discontinuous strap ribs. An open side groove is provided on the flip cover symmetric to the opening groove. Both ends of the elastic strip of the bottle cap are integrally injection-molded with the bottle cap and the flip cover of the bottle cap respectively through the bottom of the opening groove and the bottom of the side groove. The strap ribs are integrally injection-molded with the bottle cap. The above is the structural form of the flip cover and the bottle cap being integrally injection-molded. Other existing plug-in type connected hinge methods can also be used, but the method of integrally injection-molding the elastic strip with the flip cover and the bottle cap is relatively simple for production and is the best solution.

[0006] Convex ribs are equidistantly distributed inside the elastic hole of the button. A convex positioning rib is provided in the middle of the top of the elastic head of the button. The upper and lower edges of the arc-shaped side surface of the button on the symmetrically opposite side of the elastic head are respectively higher than the elastic hole of the button. The positioning rib at the elastic head of the button is inserted into the positioning groove at the opening groove. The above structure ensures the stable use of one end of the elastic head of the button and a relatively large force application pressing area on the pressing side.

[0007] A hook hole is provided at the top of the button. A buckling hook is provided on the inner side cover opening of the flip cover of the bottle cap corresponding to the hook hole. The buckling hook of the flip cover is buckled with the hook hole of the button. The above structure enhances the buckling and fixing between the flip cover and the button.

[0008] The top of the button is provided with a protruding fastening lip, which protrudes from the bottom to the outer side of the top and is integrally injection-molded. On the inner side of the cover of the flip cover of the corresponding bottle cap, there is a protruding fastening rib, and the fastening rib of the flip cover is fastened to the fastening lip of the button. The above structure can also achieve the fastening and fixing between the flip cover and the button.

[0009] The fastening lip of the button is provided with a hook hole, and the edge of the fastening lip above the hook hole is provided with a lower hook. Corresponding to the inner side of the cover of the flip cover of the bottle cap, there is an upper hook, and the upper hook of the flip cover is fastened to the hook hole of the button. The above is another fastening and fixing structure between the flip cover and the button.

[0010] On one side of the button slot of the bottle cap, there is a locking button. The sliding hooks on the upper and lower edges of the locking button are fastened and fixed to the sliding groove on one side of the button slot of the bottle cap, and the lock head on one side of the locking button is inserted into the lock hole on one side of the button inside the bottle cap.

[0011] The spring in the pump body is a metal spring. The outer diameter of the top plug of the inner plug is fastened to the inner diameter of the pump port of the pump body. The metal spring is arranged in the spring cavity inside the inner plug. One end of the metal spring abuts against the bottom of the spring cavity in the inner plug, and the other end of the metal spring abuts against the spring rib on the outer diameter of the valve stem. One end of the valve stem extends out of the inner plug and the pump body, and the other end of the valve stem is fastened to the valve needle in the pump body to form an integral body. There is a piston at the fastening place, and the valve stem and the valve needle at the fastening place are respectively provided with liquid channels that communicate with each other. The outer diameter of the piston abuts against the inner wall of the pump body for sealing. At the liquid inlet hole of the pump body below the valve needle, there is a plastic ball bead fastened and fixed, and a straw is inserted at the bottom of the liquid inlet hole of the pump body. The above is a specific structural embodiment of the pump core assembly.

[0012] The metal spring is replaced with a helical integrally formed plastic spring. The above structure facilitates the overall recycling and treatment of the makeup remover water pump head.

[0013] The structure of the present invention is reasonably designed and convenient for assembly and use. In particular, the fastening structure between the flip cover and the bottle cap has various forms, and in combination with the plastic spring structure in the pump body, it is convenient for its overall recycling; it is suitable for use as a one-key opening makeup remover water pump head and the structural improvement of its similar products.
