Description

Technical Field

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

[0002] In modern daily life, squeeze-type packaging containers have become the mainstream packaging form in the fields of cosmetics, pharmaceuticals, personal care products, and food due to their advantages such as ease of use, good sealing, and portability. Typical squeeze-type packaging includes tubes (such as toothpaste tubes and facial cleanser tubes), bottles with squeeze pump necks (such as some serum bottles and medicine bottles), and flexible bags (such as some sauce packaging). Consumers can manually apply pressure to the container wall or pump neck to squeeze out the contents for use.

[0003] For tube-type packaging products, consumers squeeze the tube to expel the contents. The amount expelled depends entirely on the applied pressure, the duration of application, and the squeezing location. Hand strength varies from person to person, and even for the same person, the squeezing force is difficult to maintain consistently at different times and under different conditions (such as hand dryness, fatigue level). This results in a highly random and uncertain amount expelled each time, making quantitative control impossible. Consumers can only rely on visual inspection and experience to make rough estimates, with extremely low accuracy. Utility Model Content

[0004] The main purpose of this invention is to propose a quantitative container that aims to solve the problem that existing containers cannot meet the quantitative liquid dispensing requirements.

[0005] To achieve the above objectives, the present invention provides a metering container, which includes:

[0006] The bottle body includes a neck and a body that are connected to each other. The interior of the body forms a cavity for storing the contents, and the neck has a through outlet hole.

[0007] A bottle cap, detachably mounted on the outside of the bottle neck; and

[0008] A metering structure is located inside the bottle body near the bottleneck. The metering structure includes a dispensing cylinder and a flexible squeezing assembly. The squeezing assembly is located on the outer periphery of the dispensing cylinder and abuts against the inner wall of the bottle body. The dispensing cylinder has a dispensing channel that communicates with the dispensing hole. A stop protrusion is provided between the squeezing assembly and the dispensing cylinder to limit the deformation range of the squeezing assembly each time. By squeezing the bottle body to compress the squeezing assembly, the liquid contents in the cavity flow through the dispensing channel to the dispensing hole.

[0009] In one embodiment, the extrusion assembly includes a first pressing plate and a second pressing plate connected to each other. The second pressing plate covers the outer periphery of the first pressing plate. One end of the first pressing plate is fixed to the outside of the liquid outlet cylinder, and the other end of the first pressing plate is bent and connected to the second pressing plate. The second pressing plate abuts against the inner wall of the bottle body.

[0010] In one embodiment, the shape of the second pressing sheet and the shape of the first pressing sheet are both arc-shaped.

[0011] In one embodiment, the stop protrusion is provided on the side of the first pressing plate facing the liquid outlet cylinder and / or on the side of the second pressing plate facing the first pressing plate.

[0012] In one embodiment, the liquid outlet cylinder is provided with a positioning post that extends into the liquid outlet hole and is in clearance fit with the hole wall of the liquid outlet hole. The liquid outlet cylinder is provided with a perforation that communicates with the liquid outlet channel so that the contents of the liquid outlet channel flow through the perforation into the gap between the positioning post and the hole wall of the liquid outlet hole.

[0013] In one embodiment, a limiting plate is provided inside the bottle body, the limiting plate is disposed near the bottleneck and protrudes into the cavity, and the end of the second pressing plate near the bottleneck abuts against the limiting plate.

[0014] In one embodiment, the bottle body is provided with an installation plate inside, the installation plate is located close to the bottleneck and inside the limiting plate, the installation plate protrudes into the cavity and engages with the liquid dispensing cylinder.

[0015] In one embodiment, the inner side of the mounting plate is provided with a first snap-fit ​​protrusion, and the end of the liquid outlet cylinder is provided with a second snap-fit ​​protrusion. The second snap-fit ​​protrusion abuts against the top of the first snap-fit ​​protrusion and is located close to the bottleneck.

[0016] In one embodiment, the mounting plate is provided with a slot, and the end of the liquid outlet cylinder is provided with a protruding insert plate, which is inserted into the slot for fixation.

[0017] In one embodiment, the bottle cap is provided with a sealing post that protrudes toward the bottleneck and is sealed to the liquid outlet.

[0018] This invention provides a quantitative structure inside the bottle, comprising a dispensing cylinder and a squeezing assembly. The dispensing cylinder has a dispensing channel connected to a dispensing hole on the bottle neck. The squeezing assembly abuts against the inner wall of the bottle, and a stop protrusion is provided between the squeezing assembly and the dispensing cylinder. When the contents of the bottle need to be removed, the user simply holds the bottle and squeezes it at the designated position on the squeezing assembly. The bottle deforms inward, reducing the volume within the cavity and increasing the internal pressure, allowing the contents to flow out through the dispensing channel and then through the dispensing hole. During the squeezing process, the stop protrusion ensures that the squeezing assembly only produces a consistent range of squeezing deformation, guaranteeing a constant volume of liquid discharged each time the bottle is squeezed. Compared to traditional squeezing containers, this container achieves quantitative dispensing, making it particularly suitable for applications requiring precise measurement, such as pharmaceuticals and cosmetics.

[0035] For tube-type packaging products, consumers squeeze the tube to expel the contents. The amount expelled depends entirely on the applied pressure, the duration of application, and the squeezing location. Hand strength varies from person to person, and even for the same person, the squeezing force is difficult to maintain consistently at different times and under different conditions (such as hand dryness, fatigue level). This results in a highly random and uncertain amount expelled each time, making quantitative control impossible. Consumers can only rely on visual inspection and experience to make rough estimates, with extremely low accuracy.

[0036] This utility model proposes a quantitative container.

[0037] Please see Figure 1 , Figure 2 and Figure 5 In one embodiment of this utility model, the metering container 100 includes:

[0038] Bottle 1 includes a neck 11 and a body 12 connected to each other. The interior of the body 12 forms a cavity for storing the contents, and the neck 11 is provided with a through outlet hole 111.

[0039] Bottle cap 2, detachably mounted on the outside of bottle neck 11; and

[0040] The metering structure 3 is located inside the bottle body 12 near the neck 11. The metering structure 3 includes a dispensing cylinder 32 and a flexible squeezing component 31. The squeezing component 31 is located on the outer periphery of the dispensing cylinder 32 and abuts against the inner wall of the bottle body 12. The dispensing cylinder 32 has a dispensing channel 321 that communicates with the dispensing hole 111. A stop protrusion 310 is provided between the squeezing component 31 and the dispensing cylinder 32. The stop protrusion 310 is used to limit the deformation range of the squeezing component 31 each time. By squeezing the bottle body 12 to compress the squeezing component 31, the contents of the cavity flow through the dispensing channel 321 into the dispensing hole 111.

[0041] The technical solution of this utility model involves setting a quantitative structure 3 inside the bottle body 12. The quantitative structure 3 includes a liquid outlet cylinder 32 and a squeezing component 31. The liquid outlet cylinder 32 has a liquid outlet channel 321 that communicates with the liquid outlet hole 111 on the bottle neck 11. The squeezing component 31 abuts against the inner wall of the bottle body 12, and a stop protrusion 310 is provided between the squeezing component 31 and the liquid outlet cylinder 32. When it is necessary to remove the contents of the bottle body 12, the user only needs to hold the bottle body 12 and squeeze the bottle body 12 at the designated position of the squeezing component 31. The bottle body 12 deforms inward, the volume inside the cavity decreases, the internal pressure increases, and the contents inside the cavity can flow out through the liquid outlet channel 321 and then through the liquid outlet hole 111. During the pressing of the squeezing component 31, the setting of the stop protrusion 310 ensures that the squeezing component 31 can only produce a constant range of squeezing deformation, ensuring that the volume of liquid discharged each time the bottle body 12 is squeezed is constant. Compared with traditional squeezing containers, this container can achieve quantitative liquid dispensing, which is especially suitable for scenarios such as pharmaceuticals and cosmetics that require precise measurement.

[0042] Specifically, the bottle body 12 and neck 11 of the bottle body 1 can be integrally formed using high-density polyethylene (HDPE) or polypropylene (PP) through a blow molding process. The bottle body 12 can be cylindrical with a wall thickness of approximately 0.5-1mm for easy gripping and squeezing. The outer periphery of the neck 11 can be provided with external threads for engagement with the internal threads inside the bottle cap 2. The diameter and length of the liquid outlet 111 are not limited; the specific diameter needs to be set according to the viscosity of the liquid contents, and the length can be 1-3cm to ensure smooth discharge of the liquid contents. The liquid outlet cylinder 32 can be a cylindrical hollow structure with an axially extending liquid outlet channel 321 inside. The two ends of the liquid outlet channel 321 are respectively connected to the cavity inside the bottle body 12 and the liquid outlet 111 on the neck 11. The extrusion assembly 31 can be an annular flange provided around the liquid outlet cylinder 32. The outer diameter of the flange should be slightly larger than the inner diameter of the bottle body 12 to ensure an interference fit with the inner wall of the bottle body 12, so that the extrusion assembly 31 can be smoothly compressed from the outside of the bottle body 12.

[0043] It should be noted that the stop protrusion 310 can be a protrusion provided inside the squeezing assembly 31 or outside the dispensing cylinder 32. Multiple protrusions can be spaced apart. During the compression of the squeezing assembly 31, when the protrusion is clamped between the outer wall of the dispensing cylinder 32 and the inner wall of the squeezing assembly 31, it indicates that the squeezing assembly 31 has reached its maximum squeezing stroke, effectively preventing excessive dispensing due to over-squeezing, thus achieving the purpose of quantitative or limited dispensing. After the dispensing is complete and the pressure is released, the bottle body 12 returns to its original shape, and the squeezing assembly 31 also returns to its original position, ready for the next use.

[0044] In the embodiments of this utility model, please refer to Figure 4 , Figure 6 andFigure 7 The extrusion assembly 31 includes a first pressing plate 311 and a second pressing plate 312 connected to each other. The second pressing plate 312 covers the outer periphery of the first pressing plate 311. One end of the first pressing plate 311 is fixed to the outside of the liquid outlet cylinder 32, and the other end of the first pressing plate 311 is bent and connected to the second pressing plate 312. The second pressing plate 312 abuts against the inner wall of the bottle body 12. The first pressing plate 311 and the second pressing plate 312 can be made of materials such as liquid silicone or thermoplastic elastomer. Bending and connecting the second pressing plate 312 to the first pressing plate 311 so that the second pressing plate 312 covers the outer periphery of the first pressing plate 311, facilitates simultaneous extrusion of the first pressing plate 311 and the second pressing plate 312, and ensures that the pressure on the second pressing plate 312 can be evenly transmitted to the first pressing plate 311, avoiding local stress concentration and damage to a part of the pressing plate. The first pressing plate 311 and the second pressing plate 312 can be manufactured by injection molding or extrusion molding, without the need for additional assembly.

[0045] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The shape of the second pressing plate 312 is the same as that of the first pressing plate 311, both of which are arc-shaped. The arc curvature of the second pressing plate 312 can be customized according to the inner diameter of the bottle body 12. For example, the radius of curvature R of the second pressing plate 312 is equal to the inner diameter of the bottle body 12 × 0.8, so that the second pressing plate 312 and the inner wall of the bottle body 12 are tightly fitted in the entire circumference. This ensures that the second pressing plate 312 always maintains effective contact with the inner wall of the bottle body 12 during the entire compression-rebound process. The arc curvature of the first pressing plate 311 can be adapted to the curvature of the second pressing plate 312 to facilitate the transmission of the extrusion force from the second pressing plate 312 to the first pressing plate 311.

[0046] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The stop protrusions 310 can be provided only on the side of the first pressure plate 311 facing the dispensing cylinder 32, with multiple protrusions evenly distributed along the edge of the first pressure plate 311. Alternatively, in other embodiments, the stop protrusions 310 can be provided only on the side of the second pressure plate 312 facing the first pressure plate 311, with multiple protrusions also evenly distributed along the edge of the second pressure plate 312. In this way, the multiple stop protrusions 310 can form an array of stop contacts, allowing the stop to be triggered at any point when the user squeezes the bottle body 12. Optionally, stop protrusions 310 can be provided on the inner sides of both the first pressure plate 311 and the second pressure plate 312, forming double stop protection to prevent the second pressure plate 312 from being subjected to extreme compression, which could lead to an increase in the dispensing volume.

[0047] In the embodiments of this utility model, please refer to Figure 2The liquid outlet cylinder 32 is equipped with a positioning post 322, which extends into the liquid outlet hole 111 and is in clearance fit with the wall of the liquid outlet hole 111. The liquid outlet cylinder 32 is also equipped with a perforation 323 that communicates with the liquid outlet channel 321, allowing the contents of the liquid outlet channel 321 to flow through the perforation 323 into the gap between the positioning post 322 and the wall of the liquid outlet hole 111. The positioning post 322 can be a cylindrical structure. When inserted into the liquid outlet hole 111, the positioning post 322 serves as an assembly reference, ensuring the coaxiality of the liquid outlet cylinder 32 and the bottleneck 11, and preventing uneven force on the extrusion assembly 31 due to assembly misalignment. The perforation 323 can be located at the top of the liquid outlet cylinder 32 or on the side of the upper end of the liquid outlet cylinder 32, so that the liquid in the liquid outlet channel 321 can flow out smoothly in the upward direction. The perforation 323 can be arc-shaped, circular, or other irregular shapes. Furthermore, a gap is formed between the outer wall of the liquid outlet cylinder 32 and the wall of the liquid outlet hole 111, allowing the liquid contents to flow out through the perforation 323 on the liquid outlet cylinder 32 and then through the gap to the liquid outlet hole 111, thus forming a precise liquid flow guiding channel and preventing the liquid from deviating or splashing during the liquid outlet process. This is especially suitable for the output of low-viscosity dilute liquids.

[0048] In the embodiments of this utility model, please refer to Figure 2 and Figure 8 The bottle body 12 has a limiting plate 121 inside, which is located near the neck 11 and protrudes into the cavity. The end of the second pressing plate 312 near the neck 11 abuts against the limiting plate 121. The limiting plate 121 can be integrally injection molded with the bottle body 12 or it can be separately processed and welded. The limiting plate 121 can be an annular boss protruding from the bottle body 12 near the neck 11, serving as a rigid support structure to provide a clear installation limit for the second pressing plate 312 and prevent displacement or skewness of the extrusion assembly 31 during long-term use. Furthermore, the upper end of the second pressing plate 312 abuts against the limiting plate 121, ensuring that only the middle part of the second pressing plate 312 deforms during the extrusion process, while the lower end of the second pressing plate 312 is fixed to the first pressing plate 311, and the upper end of the second pressing plate 312 abuts against and is fixed to the limiting plate 121.

[0049] In the embodiments of this utility model, please refer to Figure 2 and Figure 8The bottle body 12 has an internal mounting plate 122. The mounting plate 122 is located near the neck 11 and inside the limiting plate 121. The mounting plate 122 protrudes into the cavity and engages with the dispensing cylinder 32. The mounting plate 122 can also be an annular boss located inside the limiting plate 121. The mounting plate 122 and the dispensing cylinder 32 can form an interference fit through a snap-fit ​​structure. For example, a dovetail groove can be provided on the inner side of the mounting plate 122, and a dovetail protrusion can be provided on the outer side of the dispensing cylinder 32. The engagement between the dispensing cylinder 32 and the mounting plate 122 is achieved through the cooperation of the dovetail protrusion and the dovetail groove.

[0050] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The mounting plate 122 has a first snap-fit ​​protrusion 1221 on its inner side, and the dispensing cylinder 32 has a second snap-fit ​​protrusion 324 at its end. The second snap-fit ​​protrusion 324 abuts against the top of the first snap-fit ​​protrusion 1221 and is positioned close to the bottle neck 11. The first snap-fit ​​protrusion 1221 and the second snap-fit ​​protrusion 324 can be elongated protrusions, forming a stepped snap-fit ​​engagement. Optionally, a guide bevel can be provided at the upper periphery of the first snap-fit ​​protrusion 1221 and the second snap-fit ​​protrusion 324 to facilitate the insertion of the second snap-fit ​​protrusion 324 along the upper edge of the first snap-fit ​​protrusion 1221. The first snap-fit ​​protrusion 1221 can be integrally injection molded with the mounting plate 122, and the second snap-fit ​​protrusion 324 can be integrally injection molded with the dispensing cylinder 32, achieving the installation of the dispensing cylinder 32 and the bottle body 12 without additional parts. Furthermore, the mounting plate 122 and the limiting plate 121 can provide dual constraints on the quantitative structure 3, thereby improving the assembly accuracy of the quantitative structure 3.

[0051] In the embodiments of this utility model, please refer to Figure 5 and Figure 8 The mounting plate 122 has a slot 1222, and the end of the liquid outlet cylinder 32 has a protruding insert plate 325, which is inserted into the slot 1222 for fixation. The inner wall of the slot 1222 can be provided with anti-slip grooves, and corresponding protrusions are provided on the corresponding positions of the outer surface of the insert plate 325, forming a micro-fitting structure to prevent the liquid outlet cylinder 32 from rotating during the compression and squeezing assembly 31. Through the triple positioning structure of the positioning post 322, the snap-fit ​​protrusion, and the slot 1222 of the insert plate 325 on the liquid outlet cylinder 32, effective fixation of the liquid outlet cylinder 32 can be achieved.

[0052] In the embodiments of this utility model, please refer to Figure 1 and Figure 9The bottle cap 2 is provided with a sealing post 21, which protrudes towards the bottle neck 11 and is sealed to the liquid outlet 111. The sealing post 21 can be made of a flexible silicone material and can be shaped as a hemispherical protrusion or other structures. The end of the sealing post 21 can be provided with an annular sealing lip to form an interference fit with the edge of the liquid outlet 111 to achieve zero leakage sealing.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
