Description

Technical Field

[0001] The utility model relates to the technical field of lotion bottles, in particular to a simple replacement vacuum bottle. Background Art

[0002] As people's living standards improve, their demand for cosmetics is also increasing. A wide variety of cosmetics with different packaging have appeared on the market, and bottled cosmetics are even more diverse. The cosmetic bottles of bottled cosmetics on the market are mostly disposable items. When the liquid or lotion inside is exhausted, the entire cosmetic bottle is directly discarded, which causes great waste and pollution. In order to solve the above problems, some manufacturers are currently developing some replaceable lotion bottles to replace the inner bottle containing the contents so that the outer bottle can be reused.

[0003] For example, the Chinese utility model patent "A Vacuum Bottle with Replaceable Inner Bottle" with application number 202223056305.3 (authorization announcement number CN 218949997U) discloses such a replaceable vacuum bottle structure, which includes a spray head assembly, an outer bottle assembly and a replaceable inner bottle, the spray head assembly includes a rotating middle sleeve and a screw ring located on the inner side of the rotating middle sleeve, the screw ring can be rotated and lifted relative to the rotating middle sleeve, the lower end of the rotating middle sleeve is provided with a first screw interface, the lower end of the screw ring is provided with a second screw interface, the outer bottle assembly is detachably connected to the spray head assembly, a first stud threadably connected to the first screw interface is provided thereon, the replaceable inner bottle is accommodated in the outer bottle assembly, a second stud threadably connected to the second screw interface is provided thereon, and a vacuum bottle with a replaceable inner bottle is provided, which overcomes the defects that the inner bottle of the vacuum bottle cannot be replaced and is inconvenient to recycle.

[0004] However, there are certain shortcomings in the disassembly method using this type of threaded connection: since the outer bottle assembly and the nozzle assembly are fixed together by threaded connection, during the replacement of the inner bottle, the outer bottle assembly must be unscrewed from the nozzle assembly before the inner bottle can be replaced later. The outer bottle assembly often needs to be turned many times before it can be disassembled, and quick disassembly cannot be achieved; and the tightness between the nozzle assemblies is directly related to whether the replacement of the inner bottle is easy, and it is not easy for users to grasp whether the tightness between the two is in the best position. If the outer bottle assembly is too loose, although it will facilitate the replacement of the inner bottle next time, the vacuum bottle may become loose during use and affect the user experience; if it is too tight, although the possibility of automatic loosening is reduced, it may cause the inner bottle to be unable to be unscrewed during the next disassembly and affect the replacement of the inner bottle.

[0005] Therefore, how to provide a lotion bottle that can make the outer bottle disassembly easier, prevent the outer bottle from being screwed too tight, and ensure that the outer bottle will not automatically loosen during use is a problem that those skilled in the art need to solve urgently.

[0024] In this embodiment, reference Figures 1 to 5 As shown, the replacement bottle 3 can be detachably connected to the bottom of the pump head assembly 2, and the outer bottle 1 has an opening 1a at the top. The replacement bottle 3 can enter the outer bottle 1 from the opening 1a at the top of the outer bottle 1, and can also be moved out from the opening 1a at the top of the outer bottle 1. The outer bottle 1 is connected to the bottom of the pump head assembly 2 and can rotate relative to the pump head assembly 2. A first connecting surface 1b is formed on the outer peripheral surface of the opening 1a of the outer bottle 1, and a second connecting surface 2a that can be sleeved on the first connecting surface 1b from top to bottom is formed on the pump head assembly 2. A clamping groove 1c for locking the pump head assembly 2 is provided on the first connecting surface 1b, and a clamping block 2b adapted to the clamping groove 1c is convexly provided on the second connecting surface 2a. The clamping block 2b can extend into the clamping groove 1c when the pump head assembly 2 is inserted into the outer bottle 1, and can be clamped in the clamping groove 1c when the pump head assembly 2 rotates circumferentially to a set angle to lock the pump head assembly 2 on the outer bottle 1.

[0025] In order to optimize the clamping structure of the clamping groove 1c so as to better lock the pump head assembly 2 and the outer bottle 1, refer to Figure 2 and Figure 3 As shown, in this embodiment, the snap-in groove 1c includes a locking groove 1c1 and a guide groove 1c2. The top of the guide groove 1c2 extends to the edge of the opening 1a of the outer bottle 1. The locking groove 1c1 extends circumferentially around the first connecting surface 1b and is connected to the bottom of the guide groove 1c2. After the clamping block 2b is inserted into the guide groove 1c2, the pump head assembly 2 is rotated to make the clamping block 2b circumferentially snap into the locking groove 1c1, thereby fixing the pump head assembly 2 and the outer bottle 1.

[0026] Secondly, in order to prevent the pump head assembly 2 from continuing to rotate after rotating to the set position, thereby affecting the use of the vacuum bottle, refer to Figure 2 and Figure 3 As shown, in this embodiment, a limiting rib 1c3 is protruding from the locking groove 1c1, and a limiting groove 2b1 which can be adapted to the limiting rib 1c3 is provided on the clamping block 2b. When the pump head assembly 2 is rotated to the set position, the limiting rib 1c3 can be inserted into the limiting groove 2b1 to limit the pump head assembly 2 from rotating without the action of external force.

[0027] In addition, in order to enable the block 2b to be inserted into the guide groove 1c2 more quickly and accurately, refer to Figure 2 and Figure 3 As shown, in this embodiment, a bevel 1c4 is intentionally formed on the guide groove 1c2 to facilitate the insertion of the block 2b from top to bottom. Correspondingly, an outer rounded corner 2b2 is also formed on the block 2b to facilitate the insertion of the block 2b into the guide groove 1c2. The mutual cooperation between the outer rounded corner 2b2 and the bevel 1c4 enables the block 2b to be inserted into the guide groove 1c2 more accurately.
