[0023] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0024] like Figure 1 As shown in the preferred embodiment of this application, a dropper bottle 10 includes: a rigid outer shell 101, a flexible bottle body 102, a retaining ring 103, a bowl-shaped bottom shell 104, and a pressing rod 105.

[0025] The rigid outer shell 101 is cylindrical and hollow. The flexible bottle body 102 is used to contain liquid and is embedded in the hollow structure. A retaining ring 103 is installed at the upper end of the rigid outer shell 101 to restrict the upward movement of the flexible bottle body 102. The retaining ring includes a bowl mouth and a bowl bottom. The bowl mouth faces downward, and the bowl bottom is connected to the bottom of the rigid outer shell 101 to restrict the downward movement of the flexible bottle body 102. The bowl-shaped bottom shell 104 has a rectangular opening 10. 41 and a rotating shaft 1042, the rotating shaft 1042 being located within a rectangular opening 1041; a pressing rod 105, the pressing rod 105 including a head end 1051, a middle part 1052 and a tail end 1053, the middle part 1052 being rotatably connected to the rotating shaft 1042, the head end 1051 extending into the assembly gap between the rigid outer shell 101 and the flexible bottle body 102, the tail end 1053 being placed within the opening of the bowl-shaped bottom shell 104, rotating the tail end causing the head end to press against the flexible bottle body 102.

[0026] By placing the soft-sided bottle 102 containing the liquid inside the hard outer shell 101, the soft-sided bottle 102, which was originally prone to spillage, is supported by the hard outer shell 101 and is less susceptible to external forces. The only force-bearing push rod 105 is protected by the bowl-shaped bottom shell 104, making it difficult to touch when placed in a pocket or backpack, thus reducing liquid leakage caused by accidental squeezing.

[0027] At the same time, such as Figure 2 As shown, by installing a bowl-shaped bottom shell 104 at the bottom of the rigid outer shell 101, the bowl-shaped opening can accommodate fingers. By pinching the pressing rod 105 with the fingers, the force can be transmitted to the soft bottle body 102, thus retaining the characteristic of easy extrusion during use.

[0028] In summary, the liquid drop bottle 10 can prevent accidental squeezing and leakage, and can easily squeeze out liquid under the action of the squeezing rod, while retaining ease of use and reducing the probability of accidental squeezing, and has good use effect in actual application.

[0029] It can be understood that the hard shell 101 can be any material with supporting capacity, such as glass, acrylic, hard plastic (polycarbonate (PC), polystyrene (PS), phenolic plastic (PF)), etc., and the soft bottle body 102 can be any soft material with sufficient water density, such as flexible plastic (such as low-density polyethylene (LDPE), polyvinyl chloride (PVC) soft plastic, thermoplastic elastomer (TPE)). The above hard plastic, flexible plastic and other materials are only exemplary and are not used to limit the application.

[0030] In order to reduce production cost and mold cost, in an embodiment of the application, the retaining ring 103 can be integrally formed with the hard shell 101, and the bowl-shaped bottom shell 104 can be detachably connected with the hard shell 101.

[0031] Since the retaining ring 103 has a relatively simple structure, the retaining ring 103 can be integrally formed with the hard shell 101, thereby reducing a production process. The bowl-shaped bottom shell 104 is installed at the mounting opening, and the bowl-shaped bottom shell 104 is installed after being detached from the hard shell 101. The bowl-shaped bottom shell 104 with a complex structure is manufactured separately, which does not affect the implementation of the product scheme.

[0032] It can be understood that the detachable connection between the plastic shell and the bottom can adopt structures such as buckle connection, plug-in connection, magnetic attraction connection, etc., which are selected according to the actual scheme.

[0033] As shown in Figure 3 In another embodiment of the application, the liquid drop bottle 10 can further include a bottom plate 106, the bottom plate 106 is rotatably connected with the edge of the bowl-shaped bottom shell 104, and is used to cover the opening of the bowl-shaped bottom shell 104; the tail end 1053 of the pressing rod 105 is flush with the bowl opening, or the tail end 1053 of the pressing rod 105 is placed in the bowl opening.

[0034] Through the above scheme, the bottom plate 106 is installed at the bottom, which can prevent small objects in a pocket, backpack or other container from entering the bowl-shaped bottom shell 104, and further reduces the probability of accidental squeezing of the soft bottle body 102.

[0035] Therefore, in addition to the rotatable connection between the bottom plate 106 and the edge of the bowl-shaped bottom shell 104, a protruding buckle can also be arranged on the bottom plate 106 opposite the rotatable connection, and a groove is arranged on the bowl-shaped bottom shell 104, and the buckle and the groove cooperate to enable the bottom plate 106 to be fixed on the bowl-shaped bottom shell 104.

[0036] In another embodiment, a reusable adhesive material, such as a nanotape, can be used instead of the buckle and groove structure.

[0037] Similarly, in an embodiment, a magnetic structure can be used instead of the buckle and groove structure to secure the bottom plate 106 to the bowl-shaped bottom shell 104. For example, a magnet can be provided on the bowl-shaped bottom shell 104 and the bottom plate 106, and the two magnets can be arranged to face each other in a repulsive manner to provide an attractive force that secures the bottom plate 106 to the bowl-shaped bottom shell 104.

[0038] The buckle solution does not introduce additional materials and can reduce costs. The magnetic structure can be quickly opened and closed, and because there are no protruding structures, it is less likely to scratch the human body and less likely to be damaged. The adhesive material combines the advantages and disadvantages of the two solutions above, and is moderately priced and durable. The specific solution can be selected based on actual production needs.

[0039] In the present application, in order to reduce the probability of liquid contamination, in another embodiment, as shown in Figure 4 the drop bottle 10 can further include a bottle cap 107 that is detachably connected to the upper end of the hard shell 101.

[0040] By providing the bottle cap 107, the drop bottle 10 forms a sealed structure, and external debris is difficult to contact the liquid outlet, so it is difficult to contaminate the liquid in the soft bottle body 102.

[0041] It can be understood that the shape of the bottle cap 107 in the drawings is only exemplary, and the present application is not limited. In an embodiment, the shape of the bottle cap 107 can be made similar to the liquid outlet of the soft bottle body 102, so as to reduce the volume of the bottle cap 107, and make the overall structure of the drop bottle 10 more compact, and occupy less space in the bag.

[0042] In an embodiment of the present application, as shown in Figure 5 the first end 1051 of the pressing rod 105 can be provided with an arc surface structure 1054 that is in contact with the inner surface of the hard shell 101 or the outer surface of the soft bottle body 102.

[0043] By providing the arc surface structure 1054, the pressing rod 105 can be more in contact with the soft bottle body 102, and can better apply force to the soft bottle body 102. Because the contact area is increased, the squeezing effect can be achieved even when the liquid content is low, and the soft bottle body 102 will not be pierced.

[0044] It can be understood that the scheme of the present application can also be normally implemented without the arc surface structure 1054. The resilience characteristics of the soft bottle body 102 itself make it rebound after each pressing to suck in air, so that it can enter the next state of being ready to be squeezed. After the scheme with the arc surface structure 1054 is applied, because the contact area is increased, the volume squeezed in a unit distance is larger, and thus more liquid is squeezed out at a time. Therefore, the contact area of the arc surface structure 1054 and the soft bottle body 102 can be designed according to actual needs. For example, in the application scenario of disinfectant water that requires large flow, the contact area of the arc surface structure 1054 and the soft bottle body 102 can be appropriately increased, and for example, in the scenario of eye drops that require fine control of flow, the contact area of the arc surface structure 1054 and the soft bottle body 102 can be appropriately reduced.

[0045] In an embodiment of the present application, the tail end 1053 of the pressing rod 105 can be provided with a convex or concave pattern, and the outer surface of the bowl-shaped bottom shell 104 can be provided with a convex or concave pattern.

[0046] By respectively providing anti-slip patterns at the two opposite positions of the tail end 1053 of the pressing rod 105 and the outer surface of the bowl-shaped bottom shell 104, the anti-slip effect can be achieved when pinching, the probability of the fingers falling off the drop bottle 10 can be reduced, the hand feeling during use can be optimized, and the force transmission during pinching can be enhanced.

[0047] Similarly, in another embodiment, the hard shell 101 can also be provided with a protruding structure, and the protruding structure can be provided with a convex or concave pattern, and the protruding structure corresponds to the tail end 1053 of the pressing rod 105.

[0048] By providing the protruding structure at the corresponding position of the hard shell 101 and the tail end 1053, and then providing the anti-slip pattern after forming the opposite structure, the anti-slip characteristics can be further improved, and the hand feeling during use can be improved.

[0049] In an embodiment of the present application, as shown in Figure 6 The drop bottle 10 can also include a circular support plate 108, which is concentrically installed between the hard shell 101 and the bowl-shaped bottom shell 104. The circular support plate 108 is provided with an aperture 1081, and the aperture 1081 points to the center of the circular support plate 108. The difference (B-C) between the length of the rotating shaft 1042 and the length of the rectangular opening 1041 is not less than the width (A) of the middle part 1052 of the pressing rod 105, and the width difference (B-C) between the aperture 1081 and the middle part 1052 of the pressing rod 105 is between 0.5 mm and 2 mm.

[0050] By increasing the circular support plate 108, the mounting structure is optimized. When assembling, reference can be made to Figure 7The following steps can be taken: 1, the soft bottle body 102 is inserted into the hard shell 101 (not shown in the figure); 2, the pressing rod 105 is inserted into the area without the rotating shaft 1042 of the rectangular opening 1041 (①, ②, ③ in the figure), and the middle part 1052 of the pressing rod 105 is aligned with the rotating shaft 1042 and then pushed into the rotating shaft 1042 (corresponding to ③, ④ in the figure); 3, the circular support plate 108 is placed at the bottom of the hard shell 101 (corresponding to ⑤, ⑥ in the figure); 4, the first end 1051 of the pressing rod 105 is inserted into the gap between the soft bottle body 102 and the hard shell 101 (not shown in the figure); 5, (taking threaded connection as an example) the hard shell 101 and the bowl-shaped bottom shell 104 are screwed.

[0051] If step 6, the bottom plate 106 and the bottle cap 107 are installed (corresponding to ⑧ in the figure); finally, the complete drop bottle 10 is obtained (corresponding to ⑨ in the figure)

[0052] Since the gap 1081 points to the center of the circle, the pressing rod 105 which can be translated along the rotating shaft 1042 can be fixed in the middle, so that the pressing rod 105 is just installed into the gap between the soft bottle body 102 and the hard shell 101.

[0053] On this basis, the rectangular opening 1041 can be set as a hole closed on all sides, so as to increase the rigidity of the bowl-shaped bottom shell 104 and increase the durability

[0054] The working process of the present application is that the combination of the hard shell 101 and the soft bottle body 102, together with the pressing rod 105, forms a drop bottle 10 which is easy to press and not easy to accidentally overflow. At the same time, several connection structures, anti-skid structures, cost optimization, and assembly optimization are proposed.

[0055] In summary, the embodiment of the present application provides a drop bottle 10 which has a bottle body structure designed to combine the advantages of traditional hard-packaging bottles and soft-packaging bottles, solves the technical problems of difficult pressing and easy leakage, and also provides several reproducible production schemes, which proposes advanced technical schemes from design, production, use, and later maintenance, and can solve several design requirements proposed in the present application.

[0056] The above is only a preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the technical field, several improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be considered as the protection scope of the present application.
