Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a double-compartment disposable bottle. Background Technology

[0002] In the field of packaging technology, there has been a continuous search for better solutions for packaging two-component liquid products that need to be mixed. Existing mixed packaging is mainly divided into two-container and single-container forms, both of which have obvious defects.

[0003] In a dual-container design, the two materials are stored separately in two sealed containers before use. When needed, one material is poured into the other container to mix. This method requires two packaging materials, resulting in higher costs and inconvenience in use and transport. For example, carrying two containers while traveling not only takes up space but also increases the risk of loss or spillage, causing considerable inconvenience. A single-container design uses two sealed compartments within a single packaging material to store the two materials. When needed, the materials are pumped out and mixed using two pump cores. However, this type of packaging has a complex structure, cumbersome assembly and filling processes, and typically has a larger capacity, making it unsuitable for small-capacity products. This limits its application in product areas with specific packaging capacity requirements.

[0004] To address the aforementioned issues, a Chinese utility model patent, application number 202222748942.0 (authorization announcement number CN218807748U), entitled "A Piercing Mixing Double-Compartment Packaging Bottle," was developed. This bottle comprises a cap, a bottle body, a bottle bottom, an inner plug, and an inner column. The cap is secured to the outside of the upper opening of the bottle body via double snap-fits. The upper opening of the bottle bottom is engaged with the lower opening of the bottle body. The inner plug is engaged with the upper opening of the bottle bottom, and its top surface is sealed with an aluminum film. The oblique cut of the inner column is adjacent to the sealing aluminum film. This design allows for simple and convenient mixing, and the packaging is compact and lightweight, meeting the needs of single-use mixing of small volumes.

[0005] However, with the continuous changes in market demand and the increasing demands of consumers for product experience, there is still room for improvement in this type of packaging. It does not have the function of multiple bottles side by side and quick disassembly. In practical application scenarios, for some products that are easily oxidized and contaminated, such as certain high-end skin care products and medicines, if they are not properly stored after opening, the quality and efficacy of the remaining products will be affected. Single-bottle packaging cannot meet consumers' needs for multiple uses of the product and to ensure the freshness of the product each time.

[0006] Therefore, how to provide a packaging bottle that can facilitate the easy puncture and mixing of liquids in both compartments, while also enabling multiple bottles to be arranged side by side and quickly separated for single-use disposal, has become an urgent problem to be solved in the current packaging technology field. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a dual-compartment single-disposal bottle that can conveniently achieve liquid puncture and mixing in both compartments and can be arranged side by side and quickly separated to achieve single-disposal function, in light of the above-mentioned existing technology.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: the dual-compartment secondary-disposal bottle includes multiple sets of secondary-disposal units with identical structures. Adjacent secondary-disposal units are detachably connected by an easy-tear structure. Each secondary-disposal unit includes...

[0009] The first bottle body has an independent first compartment inside, and an opening at the top that connects to the first compartment;

[0010] A connecting sleeve is provided at the top opening of the first bottle body, and a sliding channel extending vertically and connecting the first compartment is provided inside. An upwardly extending spike is formed in the sliding channel.

[0011] The second bottle body has its lower end inserted into the sliding channel of the connecting sleeve and can move up and down relative to the connecting sleeve. Inside, a second compartment is formed with its bottom sealed by a sealing film. When it moves down, the sealing film can be punctured by the spikes, allowing the first and second compartments to connect.

[0012] A safety ring is located below the second bottle and can be removed. When not removed, it can restrict the second bottle from moving downwards.

[0013] To optimize the easy-tear structure so that it can be better positioned between two adjacent secondary throwing units and reduce the difficulty of separation, preferably, the first bottles of the two adjacent secondary throwing units are arranged side by side, and an extension in the shape of a sheet is connected between the outer walls of the two adjacent first bottles. The easy-tear structure includes a tear strip provided on the extension to facilitate the separation of the two adjacent first bottles.

[0014] To optimize the process, improve production efficiency, and reduce manufacturing costs, preferably, each of the first bottle bodies and the extension is integrally injection molded, and each of the first bottle bodies can be separated into independent units along the tear strip of the easy-tear structure.

[0015] To optimize the structure of the safety ring, facilitate user operation, and ensure its stable restriction of the second bottle's downward movement, preferably, the safety ring has a ring-shaped structure and is integrally formed on the top of the connecting sleeve. It is detachably connected to the connecting sleeve by setting an annular tear seam. After the safety ring is removed, the second bottle can move downward and be pierced by the spikes.

[0016] In order to better restrict the downward movement of the second bottle when the safety ring is not removed, preferably, a downwardly extending limiting wall is formed on the outer side of the second bottle, and the top of the safety ring abuts against the bottom of the limiting wall to restrict the downward movement of the second bottle.

[0017] In order to enable the mixed liquid to be better discharged, preferably, the top of the second bottle body is provided with a liquid outlet that connects to the second compartment, and the top of the second bottle body is also detachably provided with a cap that can close the liquid outlet.

[0018] To reduce manufacturing costs and facilitate the removal of the cap to open the outlet, preferably, the cap and the second bottle body are integrally injection molded, and the cap can be separated from the second bottle body under external force to allow the outlet to be connected to the outside.

[0019] To optimize the connection structure of the connecting sleeve and enhance connection stability, preferably, the top of the connecting sleeve has a flange that can abut against the top of the first bottle, and the bottom of the connecting sleeve also has a bottom wall with at least one perforation. The spike is formed on the bottom wall. The bottom wall perforation and the spike optimize the piercing effect and ensure smooth mixing.

[0020] To effectively prevent liquid leakage between the first and second compartments and ensure product quality and packaging integrity, preferably, a first sealing ring is provided between the inner wall of the opening of the first bottle and the outer wall of the connecting sleeve for sealing, and a second sealing ring is also provided between the inner wall of the sliding channel of the connecting sleeve and the outer wall of the second bottle for sealing.

[0021] Compared with the prior art, the advantages of this utility model are as follows: By setting a first chamber and a second chamber in the first and second bottles of each secondary disposal unit to store liquids of different compositions, and by setting a connecting sleeve with a spike to connect the first and second bottles respectively, when the second bottle moves downward under external force, the sealing film of the second chamber will be easily pierced by the spike, allowing the first and second chambers to be instantly connected and mixed; by setting a safety ring to effectively restrict the downward movement of the second bottle, it is possible to avoid premature mixing of the liquids in the two chambers due to accidents such as bumps and squeezing during transportation and storage. The mixing mechanism will only be triggered after the user actively removes the safety ring, providing a reliable guarantee for the safety and stability of the product; furthermore, by setting the first bottles of multiple secondary disposal units side by side and connecting them with an easy-tear structure, the user can separate individual secondary disposal units as needed along the easy-tear structure. This secondary disposal design is of great significance for products that are easily oxidized or contaminated. For example, skincare products and medicines should be used in separate new bottles each time to avoid the remaining product from spoiling due to improper storage after opening. This ensures that the product is fresh and effective every time it is used, fully guarantees product quality, and meets consumers' strict requirements for product freshness and safety.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Figures 1-6 The diagram shown is a schematic diagram of this embodiment. The dual-compartment secondary-disposal bottle in this embodiment includes multiple sets of secondary-disposal units with the same structure. Each secondary-disposal unit mainly includes a first bottle body 1, a connecting sleeve 2, a second bottle body 3, a safety ring 4, a first sealing ring 5, and a second sealing ring 6.

[0030] The specific structural descriptions of each component of the secondary throwing unit in this embodiment are as follows:

[0031] First bottle body 1, reference Figures 1 to 4 As shown, the first bottle body 1 can be made of medical-grade polyethylene or polypropylene and is integrally molded using injection molding. The multiple polishing units are arranged side-by-side, ensuring that adjacent first bottle bodies 1 are also arranged side-by-side. A sheet-like extension 1c connects the outer walls of adjacent first bottle bodies 1. A tear strip 1d is provided on the extension 1c. The tear strip 1d is created during injection molding by controlling the material thickness to form a thinner area or by setting a weakening line, thus facilitating the separation of adjacent first bottle bodies 1. Each first bottle body 1 has an independent first chamber 1a inside, used to store a liquid. Each first bottle body 1 has an opening 1b at its top connecting to the first chamber 1a. The inner wall of the opening 1b has a certain smoothness to facilitate the subsequent installation of the connecting sleeve 2.

[0032] Connecting sleeve 2, see reference Figures 3 to 4As shown, the connecting sleeve 2 is also injection molded from plastic material. It has an internal sliding channel 2a extending vertically. The inner diameter of the sliding channel 2a matches the outer diameter of the second bottle 3, ensuring smooth vertical movement of the second bottle 3 within it. A flange 2c is formed at the top of the connecting sleeve 2. The outer diameter of the flange 2c is larger than the outer diameter of the top opening 1b of the first bottle 1. When the connecting sleeve 2 is installed on the top of the first bottle 1, the flange 2c abuts against the top of the first bottle 1, providing positioning and sealing assistance. A bottom wall 2d is formed at the bottom of the connecting sleeve 2. At least one perforation 2e is provided on the bottom wall 2d. Multiple perforations 2e are shown in the figure. An upwardly extending spike 2b is integrally formed on the bottom wall 2d. The tip of the spike 2b is sharp and used to pierce the sealing film 3a at the bottom of the second bottle 3.

[0033] Second bottle body 3, reference Figures 1 to 4 As shown, the second bottle body 3 is also made of plastic and has a second compartment 3b inside. The second compartment 3b is used to store another liquid. The bottom of the second compartment 3b is sealed by a sealing film 3a, which can be an aluminum foil film or a plastic composite film, etc., and has good sealing performance. The top of the second bottle body 3 has a liquid outlet 3d that connects to the second compartment 3b. The size of the liquid outlet 3d is designed according to actual usage requirements. The top of the second bottle body 3 is also integrally injection molded with a cap 3e. The cap 3e is connected to the second bottle body 3 by a thin connecting rib. Under the action of external force, such as strong torsion or external stretching, the cap 3e can separate from the second bottle body 3, allowing the liquid outlet 3d to conduct to the outside and realize the liquid outflow. At the same time, a downward-extending limiting wall 3c is formed on the outer side of the second bottle body 3. The outer diameter of the limiting wall 3c is adapted to the outer diameter of the safety ring 4, and is used to cooperate with the safety ring 4 to limit the downward movement of the second bottle body 3.

[0034] Safety ring 4, reference Figures 4 to 6 As shown, the safety ring 4 can also be made of plastic. It has a C-shaped ring structure and is integrally formed on the top of the connecting sleeve 2. The safety ring 4 and the connecting sleeve 2 are connected by a ring tear 4a to achieve a detachable connection. The ring tear 4a can be a thin fracture line formed during the injection molding process, which makes it convenient for the user to manually tear off the safety ring 4.

[0035] First sealing ring 5 and second sealing ring 6, reference Figure 4As shown, the first sealing ring 5 includes an arc-shaped protrusion integrally formed on the inner wall of the first bottle body 1 and an arc-shaped protrusion integrally formed on the outer wall of the connecting sleeve 2. The mutual adaptation and compression of the two arc-shaped protrusions achieve a seal between the first bottle body 1 and the connecting sleeve 2. Similarly, the second sealing ring 6 includes an arc-shaped protrusion integrally formed on the inner wall of the sliding channel 2a of the connecting sleeve 2 and an arc-shaped protrusion integrally formed on the outer wall of the second bottle body 3. The mutual adaptation and compression of the two arc-shaped protrusions achieve a seal between the connecting sleeve 2 and the second bottle body 3. Of course, the first sealing ring 5 and the second sealing ring 6 can also be implemented by using a sealing ring.

[0036] The connection methods between the components are as follows:

[0037] The connection between the connecting sleeve 2 and the first bottle body 1 is referenced. Figure 4 As shown, the connecting sleeve 2 is inserted into the top opening 1b of the corresponding first bottle body 1, and the flange 2c at the top of the connecting sleeve 2 abuts against the top of the corresponding first bottle body 1. A first sealing ring 5 is provided between the inner wall of the opening 1b of the first bottle body 1 and the outer wall of the connecting sleeve 2, and the sealing connection between the two is achieved by the first sealing ring 5 to prevent liquid from leaking from the connection between the connecting sleeve 2 and the first bottle body 1.

[0038] The connection between the second bottle body 3 and the connecting sleeve 2 is referenced. Figure 4 As shown, the lower end of the second bottle 3 is inserted into the sliding channel 2a from the top of the corresponding connecting sleeve 2, allowing the second bottle 3 to move up and down relative to the connecting sleeve 2. The spikes 2b on the bottom wall 2d of the connecting sleeve 2 face the sealing membrane 3a sealing the second chamber 3b. A second sealing ring 6 is provided between the inner wall of the sliding channel 2a of the connecting sleeve 2 and the outer wall of the second bottle 3. The second sealing ring 6 ensures the seal between the second bottle 3 and the connecting sleeve 2, preventing leakage of the mixed liquid.

[0039] The fit between the safety ring 4, the connecting sleeve 2, and the second bottle body 3 is as follows (refer to...). Figures 4 to 6 As shown, the safety ring 4 is integrally formed on the top of the corresponding connecting sleeve 2. When the safety ring 4 is not removed, the top of the safety ring 4 abuts against the bottom of the limiting wall 3c on the outside of the second bottle body 3, thereby restricting the second bottle body 3 from moving downward and preventing the sealing film 3a from being punctured by the spike 2b when not in use.

[0040] The process of using this dual-compartment secondary bottle disposal system is as follows:

[0041] When the product in the dual-compartment single-use bottle needs to be used, firstly, according to the actual usage, separate the corresponding number of first bottles 1 from the side-by-side bottles along the tear strip 1d to obtain an independently usable single-use unit. Next, manually tear off the safety ring 4. At this time, the second bottle 3 is no longer restricted. The user slightly presses the cap 3e of the first bottle 1, and the second bottle 3 will move downward. The sealing film 3a at its bottom is pierced by the spike 2b in the sliding channel 2a of the connecting sleeve 2, and the first compartment 1a and the second compartment 3b are connected, and the two liquids begin to mix. Finally, apply external force to separate the cap 3e from the second bottle 3, so that the outlet 3d is open to the outside, and the mixed liquid can be taken out.

[0042] Through the above specific implementation methods, the dual-compartment single-disposal bottle of this utility model realizes convenient puncture and mixing of liquids in two compartments, and also has the function of multiple bottles side by side and quick separation for single-disposal, which can meet the user's needs in different scenarios.
