Description

Technical Field

[0001] The invention relates to the technical field of liquid containing technology, and in particular to a backflow-proof liquid containing container. Background Art

[0002] In the modern packaging industry, the packaging forms of common liquids such as water, various beverages and wine are mainly concentrated in plastic bottles, glass bottles and specific cartons. These packages are widely used in daily life and basically meet the storage, transportation and sales needs of liquid products. However, for some precious liquids, such as high-end wines, there is a serious counterfeiting phenomenon in the market due to their high economic value. Although there are some anti-counterfeiting measures at present, such as adding glass sealing balls to wine containers to increase the difficulty of imitation, this method still has obvious loopholes. Counterfeiters can counterfeit by means of punching holes, changing caps, etc. These counterfeiting behaviors not only seriously damage the rights and interests of consumers, making consumers spend high prices but buy counterfeit and shoddy products, but also have a great negative impact on the brand reputation of regular manufacturers, destroying the normal order and fair competition environment of the market.

[0003] With the continuous development of science and technology, counterfeiting techniques are becoming increasingly diverse and sophisticated. Existing conventional liquid packaging containers are no longer able to effectively curb counterfeiting. Therefore, there is an urgent need to develop a container with higher anti-counterfeiting performance to cope with the increasingly severe anti-counterfeiting situation of liquid products, protect the interests of consumers, and maintain the healthy and stable development of the market. Summary of the invention

[0004] In view of this, the present invention provides a backflow-proof liquid container to solve the above technical problems.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The bottle cap assembly comprises a bottom cover, the bottom cover comprises a bottom cover, the bottom cover comprises a bottom cover of the bottle, and the bottom cover comprises a bottom cover of the bottle.

[0007] To better implement the above technical solution, optionally, the flow control valve includes an adjusting seat and an adjusting wheel, the adjusting seat is fixed in the installation cavity, at least one section of the conduit is a hose structure and the hose is fixed in the adjusting seat, and inclined slides are respectively provided on two opposite sides of the upper part of the adjusting seat, and the two ends of the adjusting wheel are slidably arranged in the two inclined slides, and the wheel body of the adjusting wheel is pressed against the conduit, and the adjusting wheel squeezes the conduit during sliding, so that the liquid guide channel of the conduit increases or decreases.

[0008] Optionally, the top cover is provided with a strip-shaped operating hole, and the wheel body of the adjusting wheel slides between two ends of the strip-shaped operating hole.

[0009] Optionally, a supporting plate is obliquely provided in the adjusting seat, the hose portion of the conduit is placed on the supporting plate, and the adjusting wheel cooperates with the supporting plate to control the flow of the conduit.

[0010] Optionally, two groups of snap-fit ​​components are symmetrically provided in the circumferential direction of the upper end of the base, and two groups of slot components are symmetrically provided in the circumferential direction of the lower end of the top cover, and the two groups of snap-fit ​​components are correspondingly snap-fitted with the two groups of slot components.

[0011] Optionally, the avoidance hole is opened in the circumferential direction of the lower end surface of the top cover and is located between two groups of slot assemblies. The upper end of the adjustment seat has a pipe mouth portion that is clamped in the avoidance hole, and the discharge end of the catheter is inserted in the pipe mouth portion.

[0012] Optionally, a limiting plate is fixedly provided on the partition and is symmetrically arranged with the diameter of the partition as the symmetry axis, and the lower side wall of the adjustment seat is limited to the space enclosed by the limiting plate and the base.

[0013] Optionally, the connecting portion is connected to the bottle mouth of the outer support bottle via threads.

[0014] Optionally, the sealing portion is elastically sealed with the bag opening of the inflatable bag.

[0015] Beneficial effects of the present invention:

[0016] The anti-backflow liquid storage container of the present invention comprises a liquid storage bag for storing liquid, an air bag for injecting gas of a specific pressure, and the liquid storage bag is located inside the air bag. Since the air bag adopts a structure that can only inject gas but not release gas, its internal air pressure has been set to reach a preset pressure value when it leaves the factory. When the flow control valve is opened and the liquid in the liquid storage bag is gradually reduced, the air bag will exert continuous pressure on the liquid storage bag by virtue of its internal air pressure, forcing it to shrink continuously. This contraction effect makes it extremely difficult for the external liquid to be reversely injected into the liquid storage bag through the catheter, thereby effectively realizing the anti-backflow function and effectively ensuring the quality and purity of the liquid. In addition, the air bag also provides an additional protective layer for the liquid storage bag. When lawbreakers attempt to inject liquid into the liquid storage bag by piercing the outer support bottle, the air bag and the liquid storage bag, the air bag will rupture or even explode due to the piercing, causing the storage container to be completely damaged, thereby achieving the purpose of anti-counterfeiting. By providing an inflatable bag, a base, a top cover, an air core and a conduit component, the anti-backflow container of the present invention is significantly improved in anti-counterfeiting performance, greatly reducing the probability of counterfeit and shoddy products appearing in the market, and effectively maintaining the brand image of the product and the market order.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0025] See also Figures 1 to 5 An embodiment of the present invention discloses a backflow-proof liquid container, comprising a bottle body assembly and a bottle cap assembly.

[0026] like Figures 1 to 3 As shown, the bottle assembly includes a liquid storage bag 10, an air bag 20 and an outer support bottle 30 which are arranged in sequence from the inside to the outside and are independent of each other. The material of the liquid storage bag 10 is preferably polyethylene, that is, the internal volume is dynamically related to the amount of liquid contained. Specifically, as the liquid inside the liquid storage bag 10 gradually increases, its volume will increase accordingly; conversely, when the liquid decreases, the volume will also decrease. The air bag 20 is filled with gas of a specific pressure. Under the support of the outer support bottle 30, when the pressure inside the air bag 20 reaches a preset value, it will fit closely to the inner wall of the outer support bottle 30.

[0027] like Figures 2 to 5 As shown, the bottle cap assembly includes a base 40 and a top cover 50, the base 40 includes a seat body 41 and a partition 42 arranged in the seat body 41 and integrally formed with the seat body 41, the lower end of the seat body 41 has a connecting portion 411 and a sealing portion 412, the connecting portion 411 is fixedly arranged at the bottle mouth of the outer support bottle 30, the sealing portion 412 is fixedly arranged at the bag mouth of the inflatable bag 20, the upper end of the seat body 41 is fixedly provided with a top cover 50, the inner side of the top cover 50, the inner side of the top of the seat body 41 and the partition 42 together form an installation cavity, the partition 42 is fixedly penetrated with an air core 70 and a conduit 60, the air inlet end of the air core 70 and the liquid outlet end of the conduit 60 are both located in the installation cavity, the air outlet end of the air core 70 is connected to the inflatable bag 20, the side wall of the top cover 50 is provided with an avoidance hole 501, the liquid outlet end of the conduit 60 is clamped at the avoidance hole 501, and a flow control valve installed on the conduit 60 is also provided in the installation cavity.

[0028] The method of using the anti-backflow liquid storage container in the embodiment of the present invention is: first open the flow control valve, then tilt the storage container downward so that the liquid outlet end of the catheter 60 faces downward, and the liquid in the liquid storage bag 10 can be smoothly discharged through the catheter 60 under the action of gravity and the squeezing of the inflatable bag 20.

[0029] In the anti-backflow liquid container of the embodiment of the present invention, the liquid storage bag 10 is used to store liquid, and the air bag 20 is used to inject gas of a specific pressure. The liquid storage bag 10 is located in the air bag 20. Since the air bag 20 adopts a structure that can only inject gas but not release gas, its internal air pressure has been set to reach a preset pressure value when it leaves the factory. When the flow control valve is opened and the liquid in the liquid storage bag 10 is gradually reduced, the air bag 20 will exert continuous pressure on the liquid storage bag 10 by virtue of its internal air pressure, forcing it to shrink continuously. This contraction effect makes it extremely difficult for the external liquid to be reversely injected into the liquid storage bag 10 through the catheter 60, thereby effectively realizing the anti-backflow function and effectively ensuring the quality and purity of the liquid. In addition, the air bag 20 also provides an additional protective layer for the liquid storage bag 10. When lawbreakers try to inject liquid into the liquid storage bag 10 by piercing the outer support bottle 30, the air bag 20 and the liquid storage bag 10, the air bag 20 will rupture or even explode due to the piercing, causing the container to be completely damaged, thereby achieving the purpose of anti-counterfeiting. By providing the air bag 20, base 40, top cover 50, air core 70 and conduit 60 components, the anti-backflow container of the present invention is significantly improved in anti-counterfeiting performance, greatly reducing the probability of counterfeit and shoddy products appearing in the market, and effectively maintaining the brand image of the product and market order.

[0030] like Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, in an embodiment of the present invention, the flow control valve includes an adjustment seat 80 and an adjustment wheel 90, the adjustment seat 80 is fixed in the installation cavity, at least one section of the conduit 60 is a hose structure and the hose section is fixed in the adjustment seat 80, and inclined slideways 801 are respectively provided on opposite sides of the upper part of the adjustment seat 80, and the two ends of the adjustment wheel 90 are slidably arranged in the two inclined slideways 801, and the wheel body of the adjustment wheel 90 is pressed against the conduit 60. When the adjustment wheel 90 slides along the inclined slideway 801, the conduit 60 can be squeezed, so that the area of ​​the liquid guide channel of the squeezed conduit 60 section changes, and the flow rate of the liquid guide channel is increased or decreased. This flow control method is extremely simple and quick to operate, and the user can accurately control the outflow speed and flow rate of the liquid by simply sliding the adjustment wheel 90.

[0031] Specifically, the adjusting wheel 90 is a gear, and both ends of the adjusting wheel 90 are rollers. The rollers and the inclined slideway 801 adopt a sliding cooperation mode with damping, so that the adjusting wheel 90 has a certain resistance during the sliding process. When the adjusting wheel 90 stops rotating, it can be automatically locked by the damping force, thereby effectively increasing the stability of the adjusting wheel 90. This stability further ensures the accuracy and reliability of flow control, and effectively avoids the occurrence of flow loss of control due to accidental sliding.

[0032] In the embodiment of the invention, the top cover 50 is provided with a strip-shaped operating hole 502, and the wheel body of the adjusting wheel 90 slides between the two ends in the length direction of the strip-shaped operating hole 502, and the wheel body of the adjusting wheel 90 is always located in the strip-shaped operating hole 502. In order to ensure safety during transportation and storage, the anti-backflow liquid container will be wrapped with a layer of plastic film when leaving the factory, which can effectively prevent the adjusting wheel 90 from rolling due to unexpected factors such as bumps and collisions during transportation; or an openable sealing strip is set at the strip-shaped operating hole 502, and only after the sealing strip is opened can the adjusting wheel 90 be pushed to move. This greatly increases the safety of the anti-backflow container, effectively prevents the accidental outflow of liquid or the misoperation of the flow control valve when not in use, and provides all-round protection for the safety and stability of the container during transportation and storage.

[0033] like Figures 2 to 4 As shown, in an embodiment of the invention, a supporting plate 802 is obliquely provided inside the adjustment seat 80, and the hose portion of the conduit 60 is placed on the supporting plate 802. The adjustment wheel 90 cooperates with the supporting plate 802 to control the flow of the conduit 60. Specifically, the adjustment seat 80 forms a U-shaped structure with upper and lower openings using the supporting plate 802 as a bottom plate, and the inclined slide 801 is provided on the two side plates of the upper U-shaped structure.

[0034] like Figure 1 and Figure 4 As shown, two groups of snap-fit ​​components are symmetrically arranged in the circumferential direction of the upper end of the base 40, and two groups of slot components are symmetrically arranged in the circumferential direction of the lower end of the top cover 50, and the two groups of snap-fit ​​components are correspondingly snap-fitted with the two groups of slot components.

[0035] Specifically, each set of snap-fit ​​components includes two guide strips 44 and a snap-fit ​​strip 45 located between the two guide strips. Both sides of the guide strips and the snap-fit ​​strip 45 along the circumferential direction of the base 40 have open grooves. The snap-fit ​​strip 45 has a snap-fit ​​protrusion 46 on one side facing the upper end of the base 40. The snap-fit ​​component includes an inner plate 51 and an outer plate 52 integrally arranged on the lower end surface of the top cover 50. Both ends of the inner plate 51 along the circumferential direction of the top cover 50 are folded outwards to form a guide groove that cooperates with the guide strip 44 together with the outer plate 52. The outer plate 52 is provided with a snap-fit ​​groove 521 that cooperates with the snap-fit ​​protrusion 46. Through the locking cooperation between the snap-fit ​​groove 521 and the snap-fit ​​protrusion 46, the top cover 50 can be fixed on the base 40, so that the top cover 50 and the base 40 can be detachably fixedly connected. The above snap-fit ​​cooperation mode makes the connection of the bottle cap assembly more stable, and it can also be operated more conveniently when it needs to be disassembled, ensuring the stability and reliability of the overall structure of the container.

[0036] In an embodiment of the invention, the avoidance hole 501 is opened in the circumferential direction of the lower end surface of the top cover 50 and is located between the two groups of slot assemblies. The upper end of the adjustment seat 80 has a pipe mouth portion 803 that is clamped in the avoidance hole 501, and the discharge end of the catheter 60 is inserted in the pipe mouth portion 803. The provision of the pipe mouth portion 803 can lock the discharge end of the catheter 60, thereby increasing the stability of the catheter 60.

[0037] In an embodiment of the invention, a limit plate 43 is fixedly provided on the partition 42 and is symmetrically arranged with the diameter of the partition 42 as the symmetry axis. The lower side wall of the adjustment seat 80 is limited in the space enclosed by the limit plate 43 and the base 40. Specifically, the lower U-shaped structure of the adjustment seat 80 is stuck in the space enclosed by the limit plate 43 and the base 40, which can limit the horizontal direction of the adjustment seat 80.

[0038] In an embodiment of the invention, the connecting portion 411 is connected to the bottle mouth of the outer support bottle 30 by means of threads, the sealing portion 412 is elastically sealed with the bag mouth of the inflatable bag 20, the bag mouth of the inflatable bag 20 is a reinforced mouth, and the sealing portion 412 is preferably an elastic ring. During the cooperation between the connecting portion 411 and the outer support bottle 30, the elastic ring can be naturally sealed at the bag mouth of the inflatable bag 20 by virtue of its own elastic properties.

[0039] In an embodiment of the present invention, in order to facilitate the installation of the air core 70 and the connection between the conduit 60 and the base 40, a threaded hole for installing the air core 70 and a hollow plug column for inserting the conduit 60 are provided on the partition 42. The air core 70 is screwed in the threaded hole, and the liquid inlet end of the conduit 60 is inserted in the hollow plug column.

[0040] The technical solution of the present invention is described in detail above in conjunction with specific embodiments, and the described specific embodiments are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the protection scope of the present invention.
