Description

Technical Field

[0001] This utility model relates to a water emulsion bottle, and more particularly to a water emulsion bottle and its inner stopper. Background Technology

[0002] Emulsion bottles are important containers for holding emulsion-like fluids such as cosmetics. For example, Chinese utility model patent CN214127406U discloses a lightweight polymer cylindrical emulsion bottle, which includes an outer cap, an inner cap, an inner stopper, and a blow molding bottle. The inner stopper is located at the bottle mouth of the blow molding bottle, and the inner cap is located inside the cap opening of the outer cap. The cap opening of the inner cap has an outwardly flared outer ring, and the protruding edge of the outer ring engages and is fixed with the stepped opening of the outer cap. The inner cap... The outer ring of the inner cap abuts against the inner wall below the stepped opening of the outer cap. The height of the outer ring of the inner cap is lower than the height of the inner groove of the inner cap. A cap ring groove is provided between the outer diameter of the inner groove of the inner cap and the outer ring. The internal thread of the inner diameter of the inner groove is connected to the external thread of the bottle mouth of the injection blown bottle. A plug protruding inward from the center of the top of the inner groove is inserted into the liquid outlet hole at the center of the top of the inner plug for interference fit and sealing. A gap cavity with a height greater than the outer ring of the cap is provided between the top outer diameter of the inner cap and the inner top of the outer cap. The injection blown bottle is a lightweight polymer bottle. In this emulsion bottle, the inner plug is installed at the bottle mouth of the injection blown bottle only based on friction. When the product is at excessively high or low temperatures, due to the difference in thermal expansion coefficients between the inner plug and the injection blown bottle, temperature changes will cause changes in the fit dimensions, making the inner plug prone to movement or even falling off, affecting the reliability of the emulsion bottle.

The term "a" should not be construed as a limitation on the quantity.

[0029] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 7 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the emulsion bottle includes a bottle body 10 and an inner plug 20, the bottle body 10 having a bottle cavity 11 and a bottle opening 12 communicating with the bottle cavity 11, the emulsion or other fluid being contained in the bottle cavity 11 of the bottle body 10, wherein the inner plug 20 is installed in the bottle opening 12 of the bottle body 10.

[0030] It is worth mentioning that the specific type of the bottle body 10 is not limited in this utility model. For example, in a specific example, the bottle body 10 can be a blown bottle.

[0031] Specifically, the inner plug 20 includes a top cover 21 and a plug cylinder 22. The top cover 21 has a central through hole 211 and an overlapping edge 212. The plug cylinder 22 extends downward from the top cover 21, and the outer diameter of the plug cylinder 22 is smaller than the outer diameter of the top cover 21, such that the overlapping edge 212 is formed on the periphery of the top cover 21. The bottom end of the plug cylinder 22 (i.e., the end of the plug cylinder 22 facing away from the top cover 21) has an outwardly protruding retaining ring 221. Preferably, the plug cylinder 22 extends downward integrally from the top cover 21, that is, the top cover 21 and the plug cylinder 22 are integral.

[0032] After the stopper 22 of the inner stopper 20 is inserted into the bottle opening 12 of the bottle body 10, the overlapping edge 212 of the top cover 21 abuts against the opening edge of the bottle body 10. That is, the top cover 21 is used to control the depth to which the stopper 22 is inserted into the bottle opening 12 of the bottle body 10 and to prevent the inner stopper 20 from falling into the bottle cavity 11 of the bottle body 10 as a whole. The blocking ring 221 of the stopper 22 hooks onto the inner wall of the bottle body 10 in the bottle cavity 11 of the bottle body 10. In this way, the inner stopper 20 can be reliably installed in the bottle body 10. Even if the coefficients of thermal expansion of the inner stopper 20 and the bottle body 10 are different when the product is at high or low temperatures, the inner stopper 20 will not move or fall off the bottle opening 12 of the bottle body 10, so as to ensure the reliability of the emulsion bottle. After the inner plug 20 is installed on the bottle body 10, the central perforation 211 of the top cover 21 is connected to the bottle cavity 11 of the bottle body 10, so that the emulsion or other fluid contained in the bottle cavity 11 of the bottle body 10 can flow out through the central perforation 211 of the top cover 21.

[0033] It is understood that the outer diameter of the stopper 22 of the inner stopper 20 matches the inner diameter of the bottle mouth 12 of the bottle body 10. For example, the outer diameter of the stopper 22 can be slightly larger than the outer diameter of the bottle mouth 12 of the bottle body 10. Thus, when the stopper 22 is inserted into the bottle mouth 12 of the bottle body 10, the inner wall of the bottle body 10, which defines the bottle mouth 12, squeezes the stopper 22, causing a slight deformation of the stopper 22. After the bottle body 10 is inserted into the bottle opening 12, the bottle body 10 and the stopper 22 are interference-fitted, resulting in a large frictional force between the stopper 22 and the bottle body 10. In this way, on the one hand, the emulsion bottle prevents the formation of gaps between the peripheral wall of the stopper 22 and the inner wall of the bottle body 10 that defines the bottle opening 12, thus preventing leakage of emulsion or other fluids; on the other hand, the emulsion bottle ensures that the inner stopper 20 is reliably installed in the bottle body 10. Furthermore, since the retaining ring 221 of the stopper 22 is convex, its outer diameter is larger. Thus, after the stopper 22 is inserted into the bottle opening 12 of the bottle body 10, the retaining ring 221 expands upon returning to its initial state after extending into the bottle cavity 11 of the bottle body 10, allowing the retaining ring 221 to hook onto the inner wall of the bottle body 10, thereby securely installing the inner stopper 20 in the bottle body 10.

[0034] In the emulsion bottle of this utility model, the distance between the lower surface of the top cap 21 of the inner plug 20 and the upper edge of the blocking ring 221 of the plug tube 22 is the same as the height of the bottle mouth 12 of the bottle body 10. The inner diameter of the bottle mouth 12 of the bottle body 10 is smaller than the inner diameter of the bottle cavity 11. Therefore, after the plug tube 22 is inserted into the bottle mouth 12 of the bottle body 10, the blocking ring 221 can extend into the bottle cavity 11 of the bottle body 10 and hook onto the inner wall of the bottle body 10.

[0035] Reference Appendix Figure 2 , Figure 3 and Figure 4 The stopper 22 has at least one outwardly protruding mounting ring 222 in its middle portion. After the stopper 22 is inserted into the bottle opening 12 of the bottle body 10, the inner wall of the bottle body 10 that defines the bottle opening 12 presses against the mounting ring 222 of the stopper 22. In this way, the sealing and friction between the inner wall of the bottle body 10 that defines the bottle opening 12 and the outer wall of the stopper 22 are further increased. Preferably, the stopper 22 has two spaced-apart mounting rings 222 in its middle portion.

[0036] Further, the inner plug 20 includes a plug cap 23 having an insertion post 231, the insertion post 231 of the plug cap 23 being detachably inserted into the central perforation 211 of the top cover 21. When the insertion post 231 of the plug cap 23 is inserted into the central perforation 211 of the top cover 21, the plug cap 23 closes the central perforation 211 of the top cover 21 to prevent fluids such as emulsion contained in the bottle cavity 11 of the bottle body 10 from flowing out through the central perforation 211 of the top cover 21. When the insertion post 231 of the plug cap 23 is removed from the central perforation 211 of the top cover 21, the central perforation 211 of the top cover 21 is exposed to allow fluids such as emulsion contained in the bottle cavity 11 of the bottle body 10 to flow out through the central perforation 211 of the top cover 21.

[0037] In the appendix Figures 1 to 7 In this specific example of the emulsion bottle of the present invention, the outer diameter of the insert post 231 of the stopper 23 is slightly larger than the inner diameter of the central perforation 211 of the top cover 21, and the insert post 231 has a blind hole 2311. When the insert post 231 of the stopper 23 is inserted into the central perforation 211 of the top cover 21, the blind hole 2311 of the insert post 231 allows the insert post 231 to be squeezed and deformed, thereby... After the insertion post 231 of the plug 23 is inserted into the central perforation 211 of the top cover 21, the insertion post 231 of the plug 23 and the top cover 21 are interference-fitted. In this way, on the one hand, the inner plug 20 prevents the formation of gaps between the top cover 21 and the plug 23, thus preventing the leakage of fluids such as emulsions. On the other hand, the insertion post 231 of the plug 23 can be reliably held in the central perforation 211 of the top cover 21.

[0038] Preferably, the periphery of the plug 23 is connected to the periphery of the top cover 21, so that when the user operates the plug 23 to open the central perforation 211 of the top cover 21, the plug 23 will not fall off, thus preventing the plug 23 from being contaminated or lost due to falling to the ground.

[0039] Specifically, in the appendix Figures 1 to 7 In this specific example of the emulsion bottle of the present invention, the inner stopper 20 includes a deformable connector 24, one end of which is connected to the periphery of the top cap 21 and the other end of which is connected to the periphery of the stopper cap 23, thus the connector 24 is used to connect the periphery of the stopper cap 23 to the periphery of the top cap 21. Preferably, the opposite ends of the connector 24 are integrally connected to the periphery of the top cap 21 and the periphery of the stopper cap 23, respectively.

[0040] In other words, in a preferred example of the emulsion bottle of this utility model, the top cover 21, the stopper cylinder 22, the stopper cap 23, and the connector 24 of the inner stopper 20 are integrally formed. The top cover 21, the stopper cylinder 22, the stopper cap 23, and the connector 24 can be integrally formed from plastic material by injection molding.

[0041] Reference Appendix Figure 2 , Figure 6 and Figure 7 The top cover 21 has two protective protrusions 213, a receiving groove 214, a rear notch 215, and a front notch 216. The two protective protrusions 213 extend upward from the top surface of the top cover 21 in a mutually symmetrical manner. The receiving groove 214, the rear notch 215, and the front notch 216 are formed between the two protective protrusions 213, and the rear notch 215 and the front notch 216 are respectively connected to the opposite sides of the receiving groove 214. After the insert post 231 of the plug 23 is inserted into the central through-hole 211 of the top cover 21, allowing the plug 23 to be received in the receiving groove 214 of the top cover 21, the connector 24 can extend through the rear notch 215 of the top cover 21 to the receiving groove 214. A user can apply force to the plug 23 through the front notch 216 of the top cover 21, causing the insert post 231 of the plug 23 to disengage from the central through-hole 211 of the top cover 21. Preferably, the plug 23 has an operating buckle 232 that protrudes into the front notch 216 of the top cover 21. A user can apply force to the plug 23 through the operating buckle 232, causing the insert post 231 of the plug 23 to disengage from the central through-hole 211 of the top cover 21.

[0042] After the insertion post 231 of the plug 23 is inserted into the central through hole 211 of the top cover 21, allowing the plug 23 to be received in the receiving groove 214 of the top cover 21, a protective protrusion 213 is present on each of the opposite sides of the plug 23. The protective protrusion 213 can prevent the adjacent sides of the plug 23 from being subjected to force. That is, the user can only apply force to the plug 23 at the position of the front notch 216 formed between the two protective protrusions 213. In this way, during the operation of the plug 23, the inner plug 20 can prevent the connector 24 from being subjected to force.

[0043] Continue to refer to the appendix Figures 1 to 5The lotion bottle further includes an outer cap 30, which can be screwed onto the bottle body 10. When the outer cap 30 is screwed onto the bottle body 10, the inner plug 20 is hidden. Thus, during the user's carrying of the lotion bottle, the outer cap 30 can prevent the cap 23 of the inner plug 20 from being accidentally operated. After the outer cap 30 is separated from the bottle body 10, the inner plug 20 is exposed, so that the user can operate the cap 23 of the inner plug 20. In addition, after the outer cap 30 is screwed onto the bottle body 10, the outer cap 30 presses the cap 23 of the inner plug 20 against the top cover 21, so that the insertion post 231 of the cap 23 is reliably inserted into the central perforation 211 of the top cover 21, ensuring the sealing of the lotion bottle.
