Description

Technical Field

[0001] The present invention relates to a cream bottle, in particular to a rotary pressure anti-static polymer cream bottle and a preparation method thereof. Background Art

[0002] A cream bottle refers to a bottle used for storing and accessing skin creams or lotions. Generally, the bottle body and the bottle cap of such bottles are made of plastic, and some bottle bodies adopt a double-layer structure. Generally, after rotating to open the bottle cap and the inner cap, the cream in the bottle body can be taken by finger smearing. Among them, some cream bottles are extruded from a nozzle on one side by pressing, such as the patent application No. 202210876957.7 disclosed in Chinese patent literature, the application publication date is October 11, 2022, and the invention title is "Pressure-resistant polymer rotary lock pressing vacuum cream bottle and its preparation method"; this cream bottle is discharged through the liquid outlet hole on one side of the head cap after the pump core is assembled to guide the liquid. Another example is the patent application No. 200820164066.4 disclosed in Chinese patent literature, the authorization publication date is July 8, 2009, and the utility model title is "Pressing cream bottle"; this cream bottle is discharged through the small hole at the top of the pressing head after the pump core is assembled to guide the liquid. However, in the above products and similar products, the liquid is mainly discharged by pressing the head cap, and less by rotating the rotating ring on the outer diameter of the head cap. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present invention is to provide a rotary pressure anti-static polymer cream bottle and a preparation method thereof to the art, so as to solve the technical problems that existing similar products rarely adopt the combined assembly of the bottle body component and the bottle cap component, and rarely achieve liquid discharge by rotating the rotating ring on the outer diameter of the head cap, and the material preparation and production need to be improved. The purpose is achieved by the following technical solutions.

[0004] A rotary pressure type anti-static polymer cream bottle. An inner bottle is arranged inside the outer bottle of the cream bottle. While the bottle mouth of the inner bottle is buckled and fixed with the bottle mouth of the outer bottle, a large ring is arranged at the buckling part of the bottle mouth of the inner bottle and the bottle mouth of the outer bottle. A middle ring is arranged on the outer diameter of the large ring. A gasket is arranged in the gasket groove at the bottom of the large ring at the bottle mouth of the inner bottle. The outer bottle, the inner bottle and the large ring are buckled and fixed and connected as a whole. A large piston is arranged in the inner bottle. A pump core assembly buckled and fixed to the central hole of the large ring is arranged at the central hole of the large ring of the large ring. An outer cover is arranged on the outer diameter of the middle ring. The outer cover, the middle ring and the outer bottle are integrally cylindrical. The key point of its structural design is that while the large ring is buckled and fixed to the middle ring, a rotating ring buckled and fixed to the middle ring is arranged at the central hole of the middle ring which protrudes in the middle at the top of the middle ring. The outer diameter of the central hole of the rotating ring at the part where the protrusion extends out of the middle ring is provided with a rotating ring cover. The inner diameter below the central hole of the rotating cover of the rotating ring cover is buckled and fixed to the outer diameter of the central hole of the rotating ring which protrudes at the top of the rotating ring. The inner diameter of the central hole of the rotating ring at the rotating ring is provided with a head cap extending out of the rotating ring and the rotating ring cover. The central hole of the head cap inside the head cap is sleeved with the valve rod of the pump core assembly. A plug buckled and fixed to the orifice is arranged at the top orifice of the central hole of the head cap. A channel hole is arranged at the buckling and fixing part of the plug and the central hole of the head cap. The channel hole is located below the skirt of the plug. The top plane of the central hole of the head cap of the head cap is a downward concave arc top surface. The middle ring, the rotating ring and the rotating ring cover are buckled and fixed and connected as a whole; when the head cap is pressed, the channel hole at the central hole of the head cap at the skirt of the plug is opened; when the head cap is released, the channel hole at the central hole of the head cap at the skirt of the plug is closed. The above structure facilitates the connection of the middle ring, the rotating ring and the rotating ring cover as a whole and then the connection with the pump core assembly and the head cap to form a bottle cap assembly. A large piston is arranged in the inner bottle. The outer bottle, the inner bottle and the large ring are buckled and fixed and connected as a whole to form a bottle body assembly, so as to facilitate the overall automatic assembly and improve the overall firmness and stability.

The small piston inside the pump body is fixed to the orifice at one end of the valve rod inside the pump body through a valve needle. The valve needle is snap-fitted with the buckle rib above the orifice inside the orifice at this end of the valve rod and there is a clearance channel left. The outer turned-up part inside the top of the small piston abuts against the inner diameter of the orifice at this end of the valve rod, and the inner sleeve part inside the bottom of the small piston abuts against the end ring groove of the valve needle. The other end of the valve rod extends out of the pump body and the inner plug and there is a spring on the outer diameter. One end of the spring abuts against the upper spring groove below the outer diameter of the orifice at the other end of the valve rod, and the other end of the spring abuts against the limit groove at the bottom inside the upper spring cavity of the inner plug. The spring is encapsulated in the lower spring cavity of the inner plug and the upper spring cavity of the valve rod. The piston blade on the outer diameter of the small piston abuts and seals against the inner wall of the pump body. The above is a specific structural embodiment of an assembled pump core.
