Description

Technical Field

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

[0002] As the skincare product market continues to develop, the design of cosmetic containers is also constantly evolving. The pump dispenser, due to its convenience and hygiene, has become a common design in skincare product packaging. This design uses negative pressure to draw the cosmetic product out of the bottle for user consumption by pressing the pump. This design not only makes it easier for users to take out the product but also effectively reduces the product's contact with air, extending its shelf life.

[0003] However, traditional cosmetic containers typically use piston devices or flexible plastic bags to dispense the product. While piston devices are simple in structure, inexpensive, and easy to manufacture, they have certain limitations in practical use. As the product is used, the piston assembly is prone to wear due to friction, leading to seal failure, and product residue can easily remain at the end of the piston stroke. Flexible plastic bags, on the other hand, tend to fold and shrink irregularly as the product decreases. This irregular deformation affects the bottle's appearance, making it impossible to use a transparent outer bottle when using multi-layer containers, thus impacting the overall aesthetics. Furthermore, irregular folding results in insufficient negative pressure inside the bottle, preventing the complete pumping out of any remaining product. These defects not only lead to product waste but also negatively impact the user experience. Especially in the high-end skincare market, such design flaws can cause users to question product quality, thereby damaging the brand image. Utility Model Content

[0004] The purpose of this utility model is to provide a container bottle to alleviate the technical problems existing in the prior art of traditional cosmetic containers, such as the piston device being prone to wear and leakage to the bottom of the piston or residue as the amount of cosmetic material gradually decreases with use, or the flexible storage bag shrinking irregularly, making it difficult to pump out the material in the bottle, resulting in some material being unusable, and the use of double-layered bottles where the irregular shrinkage of the inner flexible storage bag prevents the use of transparent materials in the outer bottle.

[0005] The container bottle provided by this utility model includes: a storage bottle, a middle ring connecting component, a discharge pump component, and an outer bottle;

[0006] The storage bottle is used to store material. The end of the storage bottle is connected to the middle ring connecting member. The storage bottle is replaceable and includes a folding telescopic section and a connecting section. The inner cavity of the folding telescopic section is used to store material. The folding telescopic section is configured to be longitudinally folded and compressed. The connecting section has an opening for the material in the inner cavity of the folding telescopic section to flow out.

[0007] In an optional implementation,

[0008] The discharge pump component is connected to the middle ring connecting component, and the discharge pump component is used to extract the material in the storage bottle.

[0009] The discharge pump components include an upper check valve, a lower check valve, a pressing head, a lower suction pipe, and an elastic component;

[0010] The upper one-way valve is disposed in the pressing head, and the upper one-way valve is configured to prevent the material extracted by the pressing head from the elastic member from flowing back into the internal cavity of the elastic member;

[0011] The one-way valve is configured to prevent material drawn from the storage bottle from flowing back into the storage bottle;

[0012] The elastic component is connected to one end of the pressing head, and the other end of the elastic component is connected to the middle ring connecting member. The elastic component is used to give the pressing head a tendency to move away from the middle ring connecting member.

[0013] The lower suction pipe is connected to the lower one-way valve, extends through the middle ring connecting member into the folding telescopic section, and is used by the discharge pump to extract the remaining material after folding within the folding telescopic section. The lower suction pipe ensures that the remaining material in the narrow space inside the folded storage bottle is pumped out and used up. Since the storage bottle 100 and the middle ring connecting member 200 can be freely disassembled, the lower suction pipe strengthens the connection between the storage bottle 100 and the middle ring connecting member 200, making the connection more stable, preventing the material inside the bottle from overflowing, and improving the sealing performance.

[0014] In an optional implementation,

[0015] The elastic component includes a mounting cover and an elastic element;

[0016] The mounting cover is connected to the pressing head, one end of the elastic element is connected to the mounting cover, and the other end of the elastic element is connected to the middle ring connecting member.

[0017] In an optional implementation,

[0018] The bottom of the middle ring connecting member extends to form a connecting cylinder, and the connecting section is detachably connected to the inner wall of the connecting cylinder.

[0019] The outer wall of the connecting section is provided with an external thread section, and the inner wall of the connecting cylinder is provided with an internal thread section. The external thread section is threadedly connected to the internal thread section.

[0020] In an optional implementation,

[0021] The elastic element is a plastic spring.

[0022] In an optional implementation,

[0023] The discharge pump component also includes a sealing element;

[0024] The pressing head has an outflow channel communicating with the storage bottle, and the sealing member is used to seal the end opening of the outflow channel.

[0025] In an optional implementation,

[0026] The outer bottle is made of transparent material, allowing consumers to directly observe the usage of the storage bottle and easily replace it in a timely manner. The outer bottle is connected to the middle ring connecting component, and the outer bottle covers the storage bottle. The storage bottle, including the folding telescopic section and the connecting section, can also be made of transparent material, allowing consumers to directly observe the usage of the material inside the bottle, making it more aesthetically pleasing, convenient, and hygienic to use.

[0027] In an optional implementation,

[0028] The container bottle also includes a bottle cap;

[0029] The bottle cap is connected to the middle ring connecting member, and the bottle cap covers the discharge pump member.

[0030] The container provided by this utility model has a storage bottle installed on the middle ring connecting member, which stores material. A discharge pump component is installed on the middle ring connecting member to extract the material from the storage bottle. As the discharge pump component extracts the material, the storage bottle folds longitudinally in a regular pattern, reducing the internal space of the storage bottle and also acting as a piston. This makes it easier for the material in the storage bottle to flow out, and allows the use of a transparent outer bottle to increase the aesthetics and neatness of the packaging. This alleviates the technical problems of traditional cosmetic containers in the prior art, where the material in the bottle is not easy to pump out as the material gradually decreases. It also avoids the technical problems of material leakage and residue caused by wear during the use of traditional piston devices, which leads to the inability to use some material, as well as the technical problem of irregular folding and shrinkage of the bottle body limiting the aesthetics of the bottle.

[0039] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the container bottle provided in this embodiment includes: a storage bottle 100, a middle ring connecting member 200, a discharge pump member 300, and an outer bottle 400; the storage bottle 100 is used to store material, and the end of the storage bottle 100 is connected to the middle ring connecting member 200. Specifically, the bottom of the storage bottle 100 and the middle ring connecting member 200 are detachably connected, and the storage bottle 100 is replaceable; the storage bottle 100 includes a folding telescopic section 110 and a connecting section 120. The folding telescopic section 110 is configured to be able to fold longitudinally in a regular manner, and the inner cavity of the folding telescopic section 110 is used to store material; the connecting section 120 has an opening for the material in the inner cavity of the folding telescopic section 110 to flow out; the discharge pump member 300 is connected to the middle ring connecting member 200. Specifically, the discharge pump member 300 is connected to the top of the middle ring connecting member 200, and the discharge pump member 300 is used to extract material from the storage bottle 100.

[0041] The container bottle provided in this embodiment has a storage bottle 100 installed on the middle ring connecting member 200, and the storage bottle 100 contains material. A discharge pump member 300 is installed on the middle ring connecting member 200. The storage bottle 100 includes a folding telescopic section 110 and a connecting section 120. The folding telescopic section 110 and the connecting section 120 are connected to each other, that is, the folding telescopic section 110 and the connecting section 120 are an integral structure. The connecting section 120 has an opening. When the discharge pump member 300 is pressed, the material in the inner cavity of the folding telescopic section 110 flows out from the opening of the connecting section 120 and into the discharge pump member 300, and then flows out from the discharge pump member 300 for use by the user.

[0042] The inner cavity of the folding telescopic section 110 is used to store the material. The folding telescopic section 110 is specifically made of PE+POE material, which has a certain degree of elasticity. The folding telescopic section 110 can fold and expand regularly. Under the pumping action of the discharge pump component 300, air and material are sucked out of the folding telescopic section 110. The folding telescopic section 110 is further folded and compressed, reducing the inner cavity space, thus making it easier to suck out the material from the inner cavity of the folding telescopic section 110. This effectively avoids material residue in the folding telescopic section 110, pumping out as much material as possible for use. Furthermore, a transparent outer bottle 400 can be used to increase the aesthetics and neatness of the packaging bottle. This alleviates the technical problems existing in traditional cosmetic containers where, as the amount of material in the bottle gradually decreases with use, the remaining material is difficult to pump out, resulting in some material being unusable, and the irregular folding and shrinking of the bottle restricts the use of materials for the outer bottle 400.

[0043] Based on the above embodiments, in an optional embodiment, the discharge pump component 300 in the container bottle provided in this embodiment is connected to the middle ring connecting component 200, and the discharge pump component 300 is used to extract the material in the storage bottle 100.

[0044] The discharge pump component 300 includes an upper one-way valve 340, a lower one-way valve 350, a pressing head 310, and an elastic component. The upper one-way valve 340 is disposed in the pressing head 310 and is configured to prevent the material drawn from the elastic component 322 by the pressing head 310 from flowing back into the internal cavity of the elastic component 322. The lower one-way valve 350 is configured to prevent the material drawn from the storage bottle 100 from flowing back into the storage bottle 100. The lower suction pipe 360 ​​is connected to the lower one-way valve 350, extends through the middle ring connecting component 200 into the folding telescopic section 110, and is used by the discharge pump component 300 to draw out the remaining material in the folding telescopic section 110 after folding. The lower suction pipe 360 ​​can pump out and use up the remaining material in the narrow space inside the storage bottle 100 after folding. Since the storage bottle 100 and the middle ring connecting member 200 can be freely disassembled, the setting of the lower suction tube 360 ​​can enhance the connection between the storage bottle 100 and the middle ring connecting member 200, making the connection between the two more stable, the material inside the bottle is less likely to overflow, and the sealing performance is better.

[0045] Specifically, during use, pressing down the press head 310 for the first time creates a vacuum in the elastic cavity. Releasing the press head 310 causes it to spring back to its initial position, simultaneously drawing material from the storage bottle 100 into the elastic cavity via the lower suction tube 360. The lower one-way valve 350 prevents material from flowing back into the storage bottle 100 from the elastic cavity. Pressing the press head 310 again causes the material in the elastic cavity to flow out through the end opening of the outflow channel for the user. At this time, the upper one-way valve 340 prevents the discharged material from flowing back into the elastic cavity. Once the press head 310 returns to its initial position, the material in the storage bottle 100 is drawn back into the elastic cavity, and the cycle repeats. The combination of the upper one-way valve 340 and the lower one-way valve 350 significantly reduces the possibility of contamination of the material in the storage bottle 100 compared to using a single one-way valve.

[0046] One end of the elastic component is connected to the pressing head 310, and the other end of the elastic component is connected to the middle ring connecting member 200. The elastic component can generate elastic force, which is used to make the pressing head 310 have a tendency to move away from the middle ring connecting member 200, so that the pressing head 310 can automatically spring up after the user presses down.

[0047] In an optional embodiment, the elastic component includes a mounting cover 321 and an elastic element 322; the mounting cover 321 is connected to the pressing head 310, one end of the elastic element 322 is connected to the mounting cover 321, and the other end of the elastic element 322 is connected to the middle ring connecting member 200. The elastic force generated by the elastic element 322 acts on the pressing head 310 through the mounting cover 321.

[0048] In an optional embodiment, the elastic element 322 is configured as a plastic spring.

[0049] Specifically, the elastic element 322 is made of low-density polyethylene material, which is cheaper than metal springs and effectively reduces manufacturing costs.

[0050] In an optional embodiment, the bottom of the middle ring connecting member 200 extends toward the folding telescopic section 110 to form a connecting cylinder 210. The connecting section 120 is detachably connected to the inner wall of the connecting cylinder 210, allowing the storage bottle 100 to be freely disassembled from the middle ring connecting member 200 for easy replacement of the storage bottle 100. The outer wall of the connecting section 120 is provided with an external thread section 121, and the inner wall of the connecting cylinder 210 is provided with an internal thread section 211. The external thread section 121 and the internal thread section 211 are threadedly connected, and the detachable connection between the storage bottle 100 and the middle ring connecting member 200 is achieved by screwing.

[0051] In an optional embodiment, it should be noted that the middle ring connecting member 200 extends in a direction away from the connecting cylinder 210 to form a limiting cylinder. The top of the limiting cylinder has a limiting protrusion, which can prevent the pressing head 310 from coming out of the limiting cylinder, thereby ensuring that the pressing head 310 can only press and move in the limiting cylinder.

[0052] In an optional embodiment, the discharge pump component 300 further includes a sealing member 330; the sealing member 330 is specifically configured as a sealing plug, and the pressing head 310 has an outflow channel communicating with the storage bottle 100. When the pressing head 310 is pressed down, the material in the storage bottle 100 is sucked out and flows out along the outflow channel for user use. The sealing member 330 is used to block the end opening of the outflow channel. When the user is not using it, the sealing member 330 can be blocked at the end opening of the outflow channel to prevent the material in the outflow channel from flowing out.

[0053] In an optional embodiment, the container bottle further includes an outer bottle 400; the outer bottle 400 may be made of a transparent material. The outer bottle 400 is connected to the middle ring connecting member 200, the outer bottle 400 covers the storage bottle 100, and the outer bottle 400 and the middle ring connecting member 200 are configured to be detachably connected, which may be achieved by means of threads.

[0054] In an optional embodiment, the container bottle also includes a bottle cap 500, which is connected to the middle ring connecting member 200. The bottle cap 500 covers the discharge pump member 300, and the bottle cap 500 and the middle ring connecting member 200 are configured to be detachably connected. The detachable connection between the bottle cap 500 and the middle ring connecting member 200 can be achieved by a snap-fit ​​method.

[0055] The container bottle provided by this utility model features a longitudinally foldable design installed inside the storage bottle 100. As the lower suction tube 360 ​​of the discharge pump component 300 continuously draws fluid, the internal space of the storage bottle 100 gradually decreases longitudinally in a regular manner. This pistonless vacuum container design, under vacuum conditions, allows the folding bottle to fold itself regularly when fluid is drawn out, creating a piston-like function that leaves a small amount of fluid remaining inside. This design effectively avoids the air accumulation problem caused by the reduction of material in traditional cosmetic containers, thus significantly improving the material extraction efficiency. Even when the material is nearly depleted, the remaining material can be smoothly pumped out through the deformation of the storage bottle 100. The folding structure of the storage bottle 100 can dynamically adapt to changes in the volume of the material, ensuring that the internal space is always fully utilized. The synergistic effect between the discharge pump component 300 and the storage bottle 100 makes the material flow smoother and reduces pumping resistance. The outer bottle 400 can be made of transparent material, making the packaging bottle more aesthetically pleasing and tidy. In addition, the storage bottle 100 is detachably connected to the middle ring connecting member 200. After the consumer has finished using the contents, the storage bottle 100 can be easily replaced, retaining the main components of the packaging material and continuing to use the original packaging material, thus reducing the use of plastic.

[0056] In existing technologies, traditional cosmetic containers often leave some product residue on the bottom or walls of the bottle due to the inability to completely expel the contents, resulting in waste. Furthermore, similar packaging materials on the market often use piston devices, storage bags, or folding bags for their vacuum filling devices. After use, the piston is prone to wear and leakage, leading to significant residue. The storage bag also shrinks irregularly, causing residue and waste. Additionally, the irregular shrinkage of the storage bag affects aesthetics, preventing the use of transparent materials for the outer bottle 400. Therefore, most outer bottles 400 of this type of packaging on the market are opaque to conceal the irregular shape of the inner bottle. This invention, however, minimizes the possibility of residue by using a folding design for the storage bottle 100. The folding design of the storage bottle 100 tightly fits the remaining product, gradually reducing its movement space and thus completely squeezing it out. The pistonless vacuum container design, in a vacuum environment, allows the folding telescopic bottle to fold regularly as it pumps out fluid, creating a piston-like function that results in a small amount of fluid residue remaining inside the bottle. This invention utilizes a folding and telescopic inner bottle design, allowing the inner bottle to retract regularly after use. The outer bottle 400 can be made of transparent material, minimizing product residue while maintaining a clean and aesthetically pleasing appearance for the cosmetic packaging container. The storage bottle 100, including the folding and telescopic section 110 and the connecting section 120, can also be made of transparent material, allowing consumers to directly observe the product's condition through the transparent outer bottle 400, enhancing both aesthetics and hygienic use.

[0057] This invention's container design not only solves the technical challenges of material extraction and residue control but also enhances the user experience. Users can completely extract the material without additional force or inverting the container, greatly simplifying the process. It also facilitates user-replacement, reducing costs and conserving resources.

[0058] This design is not only applicable to the cosmetic container industry, but can also be extended to other scenarios that require high-precision, residue-free material extraction, such as food packaging and pharmaceutical preparation storage.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
