Description

Technical Field

[0001] This utility model relates to a vacuum bottle, specifically a lockable vacuum bag emulsion bottle. Background Technology

[0002] A vacuum bottle is a container that isolates gas from external temperature or external bacteria. Commercially available vacuum bottles typically consist of a cylindrical or elliptical container with a piston at the bottom. Some vacuum bottles on the market use an inner bag structure, such as application number 202322685340.X disclosed in Chinese patent literature, authorized on June 4, 2024, with the utility model title "A Vacuum Cosmetic Container"; others, such as application number 202120562547.6 disclosed in Chinese patent literature, authorized on December 21, 2024, with the utility model title "Perfume Bottle Assembly". However, the rectangular design of these vacuum bottles, especially those with inner bags or vacuum bags, is relatively rare. The interlocking connection structure between components is often poorly designed, making automated production and assembly difficult, as well as replacing the inner bag. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a lockable vacuum bag emulsion bottle, thereby solving the technical problems of existing similar products rarely using a rectangular structure for carrying and use, and the inconvenience of loading and unloading the internal vacuum bag, as well as the difficulty in automated production and assembly. This objective is achieved through the following technical solution.

[0004] A lockable vacuum bag emulsion bottle is disclosed, wherein the nozzle assembly of the vacuum bag emulsion bottle is fastened to the bottle body assembly. The nozzle of the nozzle assembly extends out of an opening groove or waist-shaped sliding hole on one side of the outer cover. A vacuum bag is provided inside the outer bottle of the bottle body assembly. A pump core assembly is provided at the mouth of the vacuum bag. The valve stem of the pump core assembly is connected to the liquid inlet of the cap. The key structural design features are that the top of the outer cover of the nozzle assembly has a pressing hole, and the exposed limit of the cap is located within the pressing hole of the outer cover. The bottom opening of the outer cover has a large sealing ring. At the same time, the top pump port of the pump body of the pump core assembly is fastened and fixed in the snap-lock groove of the first pump core hole in the large ring. The bottom of the pump body of the pump core assembly extends into the mouth of the vacuum bag through the second pump core hole of the cap. The vacuum bag is fixed to the second pump core hole of the cap through the flange sleeve at the mouth of the bag. A gasket is provided at the top opening of the flange sleeve of the vacuum bag extending out of the cap. The cap seal is fixedly set at the top mouth of the outer bottle. Thus, while the vacuum bag is fixed to the second pump core hole of the gland through the flange sleeve, the pump core assembly passes through the first pump core hole of the large ring and the second pump core hole of the gland, extends into the vacuum bag, and is fixedly installed in the snap-fit ​​groove inside the first pump core hole of the large ring. Further, in the above structure, the inner diameter side of the second pump core hole of the gland is provided with a bevel, thereby facilitating the flange sleeve at the opening of the vacuum bag to rotate and be inserted into place along the bevel of the second pump core hole of the gland.

[0005] The nozzle assembly and bottle assembly are fastened together in a rectangular shape. The nozzle cap is located at a pressing hole on one end corner of the top of the outer cover. The pump core assembly, the second pump core hole, and the flange sleeve are respectively located on one side of the large ring, the pressure cap, and the vacuum bag. The above is a structural embodiment with the nozzle cap located on one side, thereby achieving eccentric pressing for liquid dispensing; it can also be located in the middle, in which case the corresponding limiting structure below needs to be adjusted and improved accordingly.

[0006] The inner cavity of the outer cover, where the bottom opening of the outer cover connects to the large ring, is equipped with a sliding cover. A protruding sliding piece at the top of the large ring inserts into the sliding hole of the sliding cover. The valve stem of the pump core assembly extends out of the pump core's waist-shaped hole on one side of the sliding cover. Symmetrically arranged large ring buckles on both sides of the outer diameter of the large ring engage and fix it to symmetrically arranged outer cover buckle grooves on both sides of the bottom opening of the outer cover. Symmetrically arranged limiting posts are located outside the pump core's waist-shaped hole at the top of the sliding cover, corresponding to the cap openings on both sides of the bottom of the headgear. A toggle button is located on the other side of the sliding cover, with one end extending out of a toggle button's waist-shaped hole on one side of the outer cover. When the toggle button moves the sliding cover until the limiting post of the sliding cover is misaligned with the cap opening at the bottom of the headgear, the headgear is pressed down. The sliding cover, driven by the corresponding toggle button, serves to prevent the headgear from being pressed down while the sliding cover is locked, and to facilitate pressing the headgear after the toggle button unlocks the sliding cover.

[0007] The other end of the toggle switch is fastened and fixed to a fixing hole in the raised stepped plate on the other side of the inner sliding cover of the outer casing. The above is a specific structural embodiment of the connection and fixation between the toggle switch and the inner sliding cover of the outer casing, but other connection and fixation methods can also be used.

[0008] The inner sliding cover of the outer casing has symmetrical sliding edges on both sides of its middle outer diameter. Limiting plates symmetrically arranged on both sides of the top of the large ring below the sliding cover engage with the sliding edges on both sides of the sliding cover, allowing it to move left and right. This, in conjunction with the pump core's oblong hole in the sliding cover, limits the movement of the sliding cover.

[0009] The large ring buckles, symmetrically arranged on both sides of the outer diameter, are fastened and fixed to the outer cover buckle grooves symmetrically arranged on both sides inside the bottom opening of the outer cover. At the same time, the side buckle ribs, symmetrically arranged on the other two sides of the outer diameter, are fastened and fixed to the side buckle grooves symmetrically arranged on both sides inside the bottom opening of the outer cover.

[0010] The large ring's slider has a positioning groove at the bottom of the cap, located above the top of the slider. The slider is inserted into the positioning groove of the cap through an opening in the limiting post on one side of the sliding cover. This structure further enhances the stability of the cap during use when pressed in the unlocked state.

[0011] The pressure cap is symmetrically secured to the large ring by the pressure cap buckles on both sides of the top, and then to the large ring buckle holes symmetrically located on both sides of the bottom. This further facilitates the integration of the large ring, pressure cap, and outer cover into one unit.

[0012] The pump core assembly has a guide rod at the bottom suction pipe hole of the pump body. One end of the guide rod has three ribs arranged at equal angles. One end of the ribs is connected to the sleeve at the other end of the guide rod through an opening.

[0013] The pump body of the pump core assembly has a spring sleeve at the bottom water inlet. The valve needle above the spring sleeve is fastened to one end of the valve stem. A piston is provided on the outer diameter of the valve needle at the fastening connection. The outer diameter of the piston slides and seals against the inner wall of the pump body. The pump port of the pump body is fastened and fixed to the inner plug. A raised spring ring is provided on the outer diameter of the inner plug at the fastening and fixing point. The outer diameter of the other end of the valve stem extending out of the pump body and the inner plug is provided with an outward flange. A plastic spring is provided between the outward flange of the valve stem and the spring ring of the inner plug. The middle outer diameter of the plastic spring between the two ends is wavy. The two ends of the plastic spring are respectively limited and fixed to the grooves of the outward flange of the valve stem and the spring ring of the inner plug. One end and one side of the wavy section of the plastic spring are provided with air holes. The lower orifice of the piston inner diameter is sealed against the end ring surface of the valve needle. The outer side of the upper orifice of the piston inner diameter slides and seals against the inner wall of the valve stem orifice.
