[0001] The utility model relates to the technical field of bottles, in particular to a pressure-resistant polymer material cream bottle based on an inner and outer cover ultrasonic thread structure. Background Art

[0002] Cream jars are containers specifically designed to store various pastes or cream-like liquid cosmetics. They possess a variety of characteristics and uses and are widely used in cosmetics and pharmaceutical packaging technologies to hold highly viscous pastes or emulsions. Due to the development of various base materials and the widespread use of solvents and additives in cosmetics, consumers have increasingly demanded tighter packaging and a more refined user experience. With the development of society and the improvement of living standards, traveling has become a common practice, and carrying cosmetic bottles with them is essential, leading to the increasing popularity of cream jars.

[0003] In the prior art, the cap of a cream bottle is connected and sealed to the cream bottle by a thread, and the cap is twisted to open or seal the cream bottle. During the carrying process, the cap is easily loosened by being bumped or subjected to other external forces, resulting in a loose seal on the bottle body, which can easily cause the cream or emulsion stored in the bottle to deteriorate. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that the bottle cap is easily loosened by bumps or other external forces during carrying, resulting in poor sealing of the bottle body, which easily causes the cream or emulsion stored in the bottle to deteriorate. The utility model proposes a pressure-resistant polymer material cream bottle with an ultrasonic threaded structure of the inner and outer covers.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pressure-resistant polymer cream bottle based on an inner and outer cover ultrasonic thread structure comprises a cream bottle body, the top end of which is fixedly connected to a connecting bottle opening;

[0007] The upper side of the cream bottle body is provided with a bottle cap for sealing the bottle opening, the bottle cap comprises an outer cap and an inner cap, the inner cap is fixed inside the outer cap, and the inner cap is threadedly connected to the surface of the bottle opening;

[0008] A limiting assembly is provided between the outer cover and the connecting bottle mouth for positioning the inner cover and the connecting bottle mouth;

[0009] A group of extrusion components is provided on the upper side of the outer cover, and the extrusion components are used to start or close the limiting components.

[0010] In a possible design, the limiting assembly includes two first grooves opened in the outer cover, an extrusion block slides in each of the two first grooves, a second groove is opened in each of the two extrusion blocks, a tension spring is fixed in each of the two second grooves, the two tension springs are respectively fixed in the two first grooves, an annular gap is opened on the surface connecting the bottle mouth, and a stopper is fixed at the adjacent ends of the two extrusion blocks, and the two stoppers move inward to penetrate into the annular gap, and the two stoppers are in extrusion contact with the side walls of the annular gap.

[0011] In one possible design, the extrusion assembly includes an internally threaded ring fixed to the top of the outer cover, the internal thread of the internally threaded ring is connected to a threaded block, the bottom end of the threaded block is rotated with a fixed turntable, two extrusion rods slide inside the outer cover, the two extrusion rods are fixed to the bottom end of the fixed turntable, the two extrusion rods move downward and penetrate into the two first grooves respectively, and the two extrusion rods are respectively in extrusion contact with the inclined surfaces of the two extrusion blocks;

[0012] Wherein, a limiting ring for limiting the threaded block is fixed to the top end of the internal threaded ring.

[0013] In a possible design, a handle is fixed to the top end of the threaded block.

[0014] In a possible design, a rubber sealing gasket for sealing the connection bottle opening is fixed inside the inner cover.

[0015] In a possible design, a non-slip twist ring is fixed on the surface of the outer cover.

[0016] In this application, just like a normal bottle cap, the outer cap is twisted to drive the inner cap to rotate and be fixed on the surface connected to the bottle mouth, and then the handle is twisted to drive the threaded block to rotate, and the threaded block rotates and moves downward in the inner threaded ring. The downward movement of the threaded block drives the fixed turntable to move downward. While the fixed turntable moves downward, the threaded block rotates on the surface of the fixed turntable, and the fixed turntable drives the two extrusion rods to move downward. The two extrusion rods move downward to squeeze the inclined surfaces of the two extrusion blocks. The two extrusion blocks are squeezed and drive the two stop blocks to move in a direction close to each other, move into the annular gap, and contact the side wall of the annular gap. At this time, since the inner cap is limited by the annular gap, the inner cap cannot rotate on the surface connected to the bottle mouth.

[0017] Beneficial effects

[0018] In the present invention, the pressure-resistant polymer material cream bottle based on the ultrasonic thread structure of the inner and outer covers can achieve the effect of fixing the position of the inner cover and the connecting bottle mouth through the limiting component, so that the inner cover cannot rotate on the surface of the connecting bottle mouth;

[0019] In the utility model, the pressure-resistant polymer material cream bottle based on the ultrasonic thread structure of the inner and outer covers can achieve the effect of controlling the opening and closing of the limit assembly by squeezing the assembly;

[0020] In the present utility model, through the coordinated use of the ultrasonic threaded structure of the inner and outer covers and the limit assembly, the cream bottle of this patent has good sealing and pressure resistance, effectively preventing product leakage and deterioration. The design of the extrusion assembly makes the start and close of the limit assembly more convenient and flexible, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
