[0001] This utility model relates to the field of dropper technology, and in particular to a modular dropper. Background Technology
[0002] Cosmetic packaging dropper sets typically consist of a rubber bulb, a plastic cap, and a glass dropper. The production process involves multiple materials, each with different properties regarding corrosion, penetration, and degradation of cosmetic solutions. Therefore, a completely uniform approach is not possible, and the subsequent product recycling process incurs higher costs in terms of labor and materials. Another type is injection-molded droppers, which are formed in one piece, but usually require a separate injection mold for each size, resulting in high initial investment costs and low adaptability. Utility Model Content
[0003] Based on the above, the purpose of this utility model is to provide a modular dropper that can be designed in sections as needed, thereby reducing production costs and improving product versatility and environmental friendliness.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A modular dropper includes a dropper tube, one end of which is detachably connected to a dropper tip, and the other end of which is detachably connected to a dropper head or a connector. A rubber head is detachably connected to the connector, and the rubber head communicates with the inner cavity of the dropper tube. A cap is detachably connected to the outside of the rubber head.
[0006] As an optional solution, the dropper tube, dropper tip, dropper head, connector, and cap are all made of PP material, and the rubber head is a blend of PP material with added elastomer.
[0007] As an alternative, the dropper head and dropper tip are respectively provided with an insertion part that is interference-fitted into the straight tube of the dropper, and the surface of the insertion part is provided with a first protruding ridge.
[0008] As an alternative, one end of the connector is provided with a plug hole for interference fit insertion of the dropper tube, and a second protruding ridge is provided on the inner wall of the plug hole.
[0009] As an alternative, the other end of the connector is provided with a snap-fit part that is interference-fitted with the inner wall of the rubber head port. The rubber head port has a raised edge, and a retaining ring extends from the side wall of the connector to limit the outer edge of the raised edge. A third raised ridge is provided on the inner wall of the retaining ring.
[0010] As an optional solution, the connecting cover is provided with a snap-fit hole for the glue head to be inserted with an interference fit, and when the connecting cover and the glue head are connected in place, the protruding edge and the retaining ring abut against the inner end face of the connecting cover.
[0011] The beneficial effects of this utility model are:
[0012] This modular dropper is designed with segmented and detachable components, which allows for individual molding of each part to meet the requirements of special shapes and materials, facilitates the production of all-plastic droppers, and promotes recycling. On the other hand, it can meet the customization needs of multiple product specifications, allows for flexible replacement and use, and has low maintenance costs. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0022] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.
[0024] Example 1:
[0025] Please see Figure 1 and Figure 2 As shown, this embodiment provides a modular dropper. Compared with existing complete sets of droppers for cosmetic packaging, this modular dropper includes a dropper tube 1, one end of which is detachably connected to a dropper tip 2, and the other end of which is detachably connected to a connector 3. A rubber head 4 is detachably connected to the connector 3. The rubber head 4 communicates with the inner cavity of the dropper tube 1, and a connecting cap 5 is detachably connected to the outside of the rubber head 4.
[0026] Among them, the dropper straight tube 1, dropper tip 2, connecting seat 3, and connecting cap 5 are all made of PP material. The rubber head 4 is a blend of PP material with added elastomers (such as EPDM, EPR, TPE, POE, EVA and other modified materials) to give the rubber head 4 resilience and softness, so as to replace the rubber material, thus realizing a complete set of droppers made of PP material, which is convenient for later recycling.
[0027] Optionally, the dropper tip 2 is provided with an insertion part 21 that can be inserted into the dropper tube 1 with interference fit, and the surface of the insertion part 21 is provided with a first protrusion 22; one end of the connecting seat 3 is provided with an insertion hole 31 for the dropper tube 1 to be inserted with interference fit, and the inner wall of the insertion hole 31 is provided with a second protrusion 32; the other end of the connecting seat 3 is provided with a snap-fit part 33 that is interference fit with the inner wall of the port of the rubber head 4, the port of the rubber head 4 forms a protrusion 41, and a retaining ring 34 extends from the side wall of the connecting seat 3 to limit the outer edge of the protrusion 41, and the inner wall of the retaining ring 34 is provided with a third protrusion 35; the connecting cover 5 is provided with a snap-fit hole 51 for the rubber head 4 to be inserted with interference fit, and when the connecting cover 5 and the rubber head 4 are connected in place, the protrusion 41 and the retaining ring 34 abut against the inner end face of the connecting cover 5.
[0028] Thus, the entire modular dropper is assembled by sequentially interfering with the dropper tip 2, dropper straight tube 1, connecting seat 3, rubber head 4, and connecting cap 5; among them, the design of the first protruding ridge 22, the second protruding ridge 32, and the third protruding ridge 35 is used to improve the connection reliability and ensure the overall sealing of the modular dropper.
[0029] Example 2:
[0030] Please see Figure 3 and Figure 4 As shown, this embodiment provides a modular dropper. Compared with the existing one-piece injection molded dropper, the modular dropper includes a dropper straight tube 1, one end of which is detachably connected to a dropper tip 2, and the other end of which is detachably connected to a dropper head 6.
[0031] Among them, the dropper tube 1, the dropper tip 2, and the dropper head 6 are all made of PP material. The dropper head 6 and the dropper tip 2 are respectively provided with an insertion part 21 that is inserted into the dropper tube 1 with an interference fit. The surface of the insertion part 21 is provided with a first protruding ridge 22.
[0032] Therefore, the dropper straight tube 1, dropper tip 2, and dropper head 6 can be molded separately to meet the customization needs of various shapes and sizes, making them more flexible to use and solving the problem of needing to open a separate injection mold for a single dropper, thus reducing production costs.
[0033] In summary, this modular dropper features segmented design with detachable connections for each component. This design allows for individual molding of each component, meeting the requirements for special shapes and materials, facilitating the production of all-plastic droppers, and promoting recycling. Furthermore, it can meet the customization needs of various product specifications, enabling flexible replacement and low maintenance costs.
[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
