Description

Technical Field

[0001] This utility model relates to the field of dropper bottle technology, and in particular to a replaceable dropper bottle. Background Technology

[0002] A dropper bottle is a container used to hold liquids. It typically consists of two parts: the bottle body and the dropper. The bottle body is usually made of glass or plastic and can be used to store liquid cosmetics such as serums, foundations, and concealers. The dropper usually consists of a rubber tip and a glass or plastic tube. By squeezing the rubber tip, the liquid in the bottle is drawn up and precisely dispensed into the skin. It offers advantages such as ease of use and better control over the amount dispensed, resulting in a more even and economical application of cosmetics. Furthermore, to conserve resources, some dropper bottles are designed with replaceable inner liners; once the contents are empty, simply replace the inner liner for reuse.

[0003] For example, the Chinese utility model patent "A Novel Dropper Bottle with Replaceable Inner Liner" with application number 202022131172.6 (authorization announcement number CN214931380U) discloses such a dropper bottle structure, which includes a press cap, a dropper assembly, a connecting sleeve, a sliding sleeve, an inner liner, a limiting cap, and a bottle body. The press cap is installed on the top of the dropper assembly, which is placed inside the inner liner. The connecting sleeve is threaded to the top of the inner liner, and a sliding sleeve is fitted on the outside of the connecting sleeve. The press cap is fitted inside the upper end of the sliding sleeve. The inner liner is placed inside the bottle body, and a limiting cap is fixed to the top of the bottle body. The limiting cap is press-fitted onto the inner liner. The inner wall of the limiting cap has a limiting protrusion and a snap-fit ​​protrusion. A ring-shaped cloth strip is provided on the outer periphery of the top of the bottle body. The limiting protrusion, the snap-fit ​​protrusion, and the ring-shaped cloth strip cooperate with each other. The specially shaped middle limiting plate in the upper part of the inner liner cooperates with the bottle body, and the limiting cap fixes the bottle body, thereby achieving a firm installation and replaceability.

[0004] However, there are some problems here. Since only the inner liner is being replaced, while the outer bottle is still the old one and not replaced at the same time, the size of the inner liner can only be limited. In addition, the length of the dropper assembly is also fixed. Even if the inner liner is replaced with a different size, the dropper assembly will not be able to fit the new inner liner, which will affect subsequent use. If the length of the dropper assembly is to be changed to fit the new inner liner, the entire dropper assembly must be replaced, which will cause unnecessary waste.

[0005] Therefore, how to provide a dropper bottle that can be replaced with different sizes of replacement bottles and can also quickly adapt the original dropper assembly to the new replacement bottle is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a replaceable dropper bottle that can replace bottles of different specifications and allows the original dropper assembly to be quickly adapted to the new replacement bottle, in contrast to the above-mentioned prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The replaceable dropper bottle includes a dropper assembly, a shoulder sleeve, and a replaceable bottle body. The bottle body is detachably connected to the bottom of the shoulder sleeve through a first detachable structure. The top of the bottle body has an opening. The dropper assembly can enter the bottle body from the top opening and can also be moved out from the top opening. The dropper assembly is also detachably connected to the shoulder sleeve through a second detachable structure. The dropper assembly also has a detachable replacement tube extending downward to adapt to bottle bodies of different sizes.

[0008] To optimize the overall structure of the dropper assembly and enable it to be better installed on the shoulder sleeve and detachably connected, the dropper assembly preferably includes a dropper sleeve and a dropper head disposed on the dropper sleeve. The second detachable structure is disposed between the dropper sleeve and the shoulder sleeve. The dropper head has a liquid storage area inside, and the bottom of the dropper head has an insertion hole that can penetrate the liquid storage area. The replacement tube can be detachably inserted into the insertion hole.

[0009] To optimize the connection structure of the second detachable structure and enable it to better fit between the dropper sleeve and the shoulder sleeve, preferably, the dropper sleeve is rotatably mounted on the shoulder sleeve. The second detachable structure includes a snap-fit ​​portion protruding radially on the outer circumferential surface of the shoulder sleeve and a snap-fit ​​groove formed circumferentially on the inner circumferential wall of the dropper sleeve and capable of fitting the snap-fit ​​portion. During relative rotation of the dropper sleeve and the shoulder sleeve, the snap-fit ​​portion can be fixed circumferentially in the snap-fit ​​groove or disengaged circumferentially from the snap-fit ​​groove.

[0010] To optimize the overall structure of the snap-fit ​​part and enable it to be better molded onto the shoulder sleeve, preferably, the top of the shoulder sleeve has an upwardly extending neck, and the outer peripheral surface of the neck has a connecting part with a triangular cross-section. Each of the three corners of the connecting part has a smoothly transitioned arc-shaped protrusion, and the arc-shaped protrusion forms the aforementioned snap-fit ​​part.

[0011] To optimize the overall structure of the snap-fit ​​groove and allow it to be better formed on the inner circumferential wall of the dropper sleeve, preferably, a connecting wall protruding inward is formed on the inner circumferential wall of the dropper sleeve. The snap-fit ​​groove is located on the connecting wall and extends circumferentially to the inner circumferential wall of the dropper sleeve. The connection between the snap-fit ​​groove and the inner circumferential wall of the dropper sleeve forms an inlet for the snap-fit ​​part to enter and exit the snap-fit ​​groove. During the rotation of the shoulder sleeve, the snap-fit ​​part can enter the snap-fit ​​groove circumferentially from the inlet or disengage circumferentially from the snap-fit ​​groove.

[0012] To prevent the dropper assembly from detaching itself when not in use, preferably, the entrance of the snap-fit ​​groove is provided with a limiting part that protrudes above the inner circumferential wall of the dropper sleeve to restrict the snap-fit ​​part from freely entering and exiting the snap-fit ​​groove, and the cross section of the limiting part is semi-circular.

[0013] To enable the bottle to be better installed at the bottom of the shoulder sleeve and to achieve a detachable connection for easy and quick replacement of the bottle, preferably, the shoulder sleeve has a downwardly extending mounting wall inside. The first detachable structure includes an internal thread on the inner circumferential surface of the mounting wall and an external thread on the outer circumferential surface of the bottle mouth. The shoulder sleeve and the bottle are detachably connected together by the threaded connection of the internal and external threads. A limiting device is also provided between the internal and external threads to prevent the bottle from being over-tightened or loosening on its own.

[0014] To prevent the bottle from being overtightened or loosening on its own, preferably, the limiting device includes mutually adaptable limiting ribs and limiting grooves. The limiting ribs are vertically disposed on the outer circumferential surface of the bottle mouth and connected to the bottom of the external thread. A limiting block is formed on the inner circumferential surface of the mounting wall adjacent to the tail of the internal thread. The gap between the limiting block and the tail of the internal thread forms the limiting groove. When the bottle is tightened to the predetermined position, the limiting ribs can adapt to the limiting groove to prevent the bottle from being overtightened or loosening on its own.

[0015] In order to better fix the replacement tube in the socket, preferably, a tapered wall that tapers inward from bottom to top is formed at the bottom entrance of the socket, and a clamping part higher than the inner wall of the socket is formed at the connection between the tapered wall and the inner wall of the socket.

[0016] Compared with the prior art, the advantages of this utility model are as follows: The first detachable structure allows the bottle body to be detachably connected to the bottom of the shoulder sleeve, enabling the empty bottle to be quickly replaced by other bottles of different sizes. The second detachable structure allows the dropper assembly to be detachably connected to the shoulder sleeve, allowing the dropper assembly to easily enter and exit the bottle body from the top opening. Furthermore, the downward-extending, quickly detachable replacement tube on the dropper assembly allows for selection of the most suitable replacement tube based on the size of the replaced bottle. This solves the drawback of the prior art where the size limitations of the outer bottle and dropper assembly prevent the replacement of inner liners of different sizes. When a replacement bottle of a different size is needed, only a replacement tube of appropriate length needs to be selected, reducing unnecessary waste. It also boasts advantages such as simple structure and ease of use. Attached Figure Description
