Description

Technical Field

[0001] The utility model relates to the technical field of packaging bottles, in particular to a roller bottle which is convenient for disassembly and recycling. Background Art

[0002] Most deodorant bottles are disposable. Since a roller ball is installed at the bottle mouth, they are also called roller bottles. The roller ball on such roller bottles is generally a plastic roller ball, which brings out the deodorant by rolling. In order to have a better experience, the roller ball is often made of steel ball, which leads to an increase in cost. In order to save costs, the relatively expensive parts such as the roller ball and the outer bottle should be recycled, and only the inner liner containing the deodorant needs to be replaced. Therefore, some packaging bottle structures with replaceable inner liners have emerged.

[0003] For example, the Chinese utility model patent "Deodorant packaging bottle with replaceable bottom of liner" with application number 20202222544651.X (authorization announcement number CN219042598U) discloses such a roller bottle structure, which includes a bottle body, an liner threadedly matched in the bottle body, a roller matched in the inner cavity of the upper part of the bottle body, and an outer cover matched in the upper part of the bottle body; the upper part of the liner is an liner head, and the outer part of the liner head is provided with an outer thread of the liner head; the bottle body is a stepped hollow tubular structure, the upper part of the bottle body is the bottle head, and the upper end of the bottle head has an inner arc tube extending downward from the inside of the upper end of the bottle head, and the inner arc tube of the bottle body is matched with a roller, and the lower end of the inner arc tube of the bottle body is vertically fixed with an inner spiral tube of the bottle body, and the inner wall surface of the inner spiral tube of the bottle body is provided with an inner thread of the bottle body, and the inner thread of the bottle body is matched with the outer thread of the liner head. The utility model can recycle the roller and the bottle body through the bottom-replaceable liner, saving energy and reducing materials.

[0004] However, this type of roller bottle also has certain problems. Since the inner liner and the outer bottle are connected by threads, when the two need to be separated, the inner liner must be removed from the outer bottle by rotating it. Due to structural limitations, the bottom of the inner liner needs to be at least partially exposed at the bottom of the outer bottle for the user to grab and rotate. Therefore, an obvious gap will be formed between the inner bottle and the outer bottle, which affects the appearance. In addition, since the inner liner is a consumable part that needs to be replaced frequently, its appearance texture is not as advanced as that of the outer bottle. The split two-section structure directly reduces the overall appearance of the bottle.

[0005] Therefore, how to provide a roller bottle that can make the separation and recycling between the inner liner and the outer bottle easier and also prevent the appearance of a seam on the outer bottle is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

When the liner of the liner assembly needs to be replaced, the liner assembly and the outer bottle assembly only need to be disassembled and separated, and the liner can be quickly replaced. The connecting seat with the ball is disassembled from the old liner and then installed on the new liner for reuse. The only part of the entire roller bottle that needs to be replaced is the liner. Since the liner assembly is detached upward, there is no need to set an opening at the bottom of the outer bottle assembly, so the outer bottle assembly and the liner assembly will not form an obvious gap, which greatly improves the overall aesthetics of the bottle. In addition, by cleverly setting the detachable structure between the liner assembly and the outer bottle assembly, the liner assembly can be quickly detached from the outer bottle assembly upward by directly grabbing the liner assembly, so that the disassembly and recycling between the liner assembly and the outer bottle assembly can be simpler and more convenient.

The outer bottle assembly 1 and the inner liner assembly 2 are locked together by providing a detachable structure 3. The inner liner assembly 2 includes a connecting seat 2a and an inner liner 2b which is detachably arranged at the bottom of the connecting seat 2a for replacement. The connecting seat 2a is provided with a liquid outlet channel 2a1 for connecting to the inner liner 2b, and the outlet end of the liquid outlet channel 2a1 is also provided with a ball 2a2 for liquid discharge. When the outer bottle assembly 1 and the inner liner assembly 2 are in a mutually locked state, the ball 2a2 is exposed at the top opening 1a of the outer bottle assembly 1.

[0029] In order to optimize the overall structure of the inner liner assembly 2, so that the connection seat 2a of the inner liner assembly 2 can better connect the outer bottle assembly 1 and the inner liner 2b, refer to Figure 2 and Figure 4 As shown, in Example 1, a step surface 2a3 adapted to the edge of the top opening 1a of the outer bottle assembly 1 is provided on the outer side wall of the connecting seat 2a, a ring wall 2a4 extending downward is formed at the bottom of the connecting seat 2a, a first external thread 2b1 is provided on the inner liner 2b, and a first internal thread 2a5 threadedly connected to the first external thread 2b1 is formed on the inner circumferential surface of the ring wall 2a4, so that the inner liner 2b can be quickly replaced through the quick connection of the thread.

[0030] Secondly, in order to better interlock or disengage the inner liner assembly 2 and the outer bottle assembly 1, refer to Figures 2 to 4 As shown, in Example 1, the detachable structure 3 includes a positioning block 3a arranged on the inner wall of the outer bottle assembly 1 and a positioning groove 3b arranged on the outer wall of the inner liner 2b. The inner wall of the outer bottle assembly 1 is also provided with a vertically arranged guide bar 1b, and the outer wall of the inner liner 2b is provided with a guide groove 2b2 extending to the bottom and allowing the guide bar 1b to move up and down. When the inner liner assembly 2 enters the outer bottle assembly 1 from top to bottom to the set position, the positioning block 3a can be adapted in the positioning groove 3b to lock the outer bottle assembly 1 and the inner liner assembly 2 together.

[0031] In addition, in order to make the locking between the inner liner component 2 and the outer bottle component 1 more firm and stable, refer to Figure 6 As shown, in Example 1, a plurality of positioning blocks 3a are provided, and each positioning block 3a is distributed on the inner wall of the outer bottle assembly 1 at intervals along the circumferential direction.
