Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a liquid passage control component. Background Art

[0002] Many products currently consist of two liquids, or a liquid and a solid, such as pharmaceutical protein products, AB glue, hair dye, facial masks, and so on. These products typically require mixing before use to ensure the optimal effect of the liquid components. Before use, they are packaged separately, either liquid-to-liquid or liquid-to-solid.

[0003] There are many ways to package this type of product. Taking liquid packaging as an example, you can directly use two independent containers to place them separately. However, this is inconvenient for both transportation and use, and it also increases the cost of packaging. As for the method of packaging two liquids together, most existing packaging methods of this type use structures such as "virtual seal sections" and "easy-to-break" on the same packaging bag. With the help of such structures, the internal space of the packaging bag is divided into two parts, and the two spaces are used to place two liquids respectively. When it is needed, one of the bags is squeezed, and the liquid inside breaks through the partition of the packaging bag and enters the space of the other bag. Although this type of structure can basically meet the need to isolate liquids under normal conditions, its isolation reliability is relatively low. Because the packaging of these products all uses flexible bags, if one of the storage areas is squeezed or impacted by external force, the isolation structure is very likely to be damaged by the pressure of the liquid, resulting in the loss of the original packaging function, affecting the use of the product. In severe cases, the product may be damaged during transportation and sale. Utility Model Content

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] See also Figure 1-Figure 7 , this application provides the following technical solutions:

[0051] A liquid passage control component includes a shell 1 with a chamber 11 formed therein; a first channel 12 and a second channel 13 are respectively provided on the shell 1. One end of the first channel 12 and the second channel 13 are connected to the chamber 11, and the other end is connected to an external bag body respectively. The extension line of the axis of the first channel 12 toward the chamber 11 is line a; the extension line of the second channel 13 toward the chamber 11 is line b, and lines a and b do not intersect. A movable component 2 is movably connected to the shell 1, and one end of the movable component 2 extends into the chamber 11. The part located in the chamber 11 can slide in the chamber 11, and the other end of the movable component 2 is located outside the chamber 11; the movable component 2 can close the connection between the first channel 12 or the second channel 13 and the chamber 11.

[0052] This solution uses the shell 1 and the movable component 2 as a control structure for the liquid passage between the two storage spaces during liquid-liquid or solid-liquid packaging. Taking the storage of two liquids as an example, the two liquids are placed in a bag body respectively, and the two bags are connected by the shell 1. The first channel 12, the chamber 11, and the second channel 13 serve as liquid passages, and the movable component 2 controls the opening and closing of the passage. The first channel 12 and the second channel 13 of this solution can both be used as liquid inlet or outlet channels. Either one of them can be closed by the movable component 2. In the structure of this solution, because the first channel 12 and the second channel 13 do not need to be coaxially arranged, the connection between the shell 1 and the two bags can be more flexible. Various forms are possible, including the first channel 12 and the second channel 13 being arranged opposite, adjacent, or on the same side. The function of the movable component 2 of this solution is to close the channel opening of the first channel 12 or the second channel 13. When the movable component 2 is avoided, the channel opening is opened, and the liquid path is connected. The movable component 2 of this solution does not involve the passage of liquid, so the processing flow is simpler and the processing technology requirements are also lower.

[0053] Based on the above embodiment, the shell 1 is a columnar body, and the chamber 11 is a cylindrical cavity opened in the shell 1. The chamber 11 is opened along the length direction of the shell 1, and the chamber 11 passes through one end of the shell 1 to form an open end; for the sake of convenience of explanation, the length direction of the shell 1 is taken as the longitudinal direction, and the open end of the shell 1 is taken as the upper end.

[0054] The movable assembly 2 comprises an inner member 21 and an outer member 22. The inner member 21 is positioned within the chamber 11 and is slidably connected thereto. One end of the inner member 21 extends to the open end of the housing 1. The outer member 22 is disposed on the exterior of the housing 1 and is interlocked with the inner member 21, driving the inner member 21 to slide within the chamber 11. The interlocking structure between the outer member 22 and the inner member 21 can take a variety of different forms, as long as the movement of the outer member 22 is transmitted to the inner member 21, which in turn is converted into movement of the inner member 21 toward the open end of the housing 1.

[0055] Based on the above implementation plan, see Figure 4 The first channel 12 and the second channel 13 are both straight slots opened on the wall of the chamber 11, and the straight slots include a rectangular portion and a circular arc portion. The rectangular portion is a rectangular through hole, and the circular arc portion is provided at both ends of the rectangular portion, which is an arc-shaped opening; the rectangular portion and the circular arc portion are connected to form an integrated slot structure. The straight slots of the first channel 12 and the second channel 13 are the same in shape and size. This shape of the slot structure allows the liquid to pass through faster. Although the positions of the first channel 12 and the second channel 13 are staggered, the speed of liquid passage will not be affected when combined with a larger slot structure.

[0056] Based on the above implementation plan, see Figure 4 , the projections of the first channel 12 and the second channel 13 on the longitudinal section of the housing 1 do not overlap. As before, the positional relationship between the first channel 12 and the second channel 13 can be modified accordingly according to actual packaging requirements. Figure 4 The figure shows the two side bags positioned on opposite sides of the housing 1. The arrangement of the first channel 12 and the second channel 13 can be adjusted, and the corresponding bags can be positioned at the corresponding connection points. The arrangement of the first channel 12 and the second channel 13 in this solution is less restricted by other structures, allowing for greater flexibility and adjustment based on demand. This also enriches the packaging's diversity and makes it easier for users to experience freshness.

[0057] On the basis of the above implementation plan, Figure 4 For example, this solution adopts a configuration in which the first channel 12 and the second channel 13 are located on opposite sides of the housing 1; the second channel 13 is located near the open end of the housing 1; the first channel 12 is located below the second channel 13. The inner part 21 of the movable component 2 can close the second channel 13; when the inner part 21 moves toward the outside of the housing 1, that is, when the inner part 21 moves toward the outside of the housing 1, the inner part 21 moves toward the Figure 4 The inner member 21 moves upward and avoids the second channel 13 , and the second channel 13 can be communicated with the chamber 11 , and then the first channel 12 and the second channel 13 are communicated with each other.

[0058] Based on the above embodiment, the inner member 21 corresponds to the shape of the chamber 11; the inner member 21 is cylindrical, and the movable assembly 2 also includes a sealing assembly 23. The sealing assembly 23 comprises four sealing rings, arranged in pairs around the movable assembly 2. A spacing is left between the two sets of sealing rings, which is greater than or equal to the length of the straight slot in the second channel 13. In the initial state of the product, that is, when the movable assembly 2 closes the second channel 13, the sealing rings of the sealing assembly 23 are located above and below the second channel 13, respectively, ensuring a sealed seal on the second channel 13.

[0059] Based on the above implementation plan, see Figure 1 、 Figure 2 and Figure 7The outer part 22 is a plate body, and the circumference of the outer part 22 includes four arc parts, two of which extend to the lateral sides of the shell 1 respectively, and the other two arc parts are arranged along the longitudinal direction of the shell 1. The distribution of the four arc parts is approximately in the shape of a "cross". The two sides of the middle part of the outer part 22 are concave structures, and the concave structure is a smooth transition surface, which smoothly transitions from the middle to the edge of the outer part 22. The function of the outer part 22 is to facilitate user operation. The lower end of the outer part 22 is fixedly connected to the inner part 21, and the two are an integrated structure, which is easier to process and manufacture. The arc part and the concave structure of the outer part 22 are to provide the user with a better force point. Whether rotating or pulling the outer part 22, it is easier to transfer the hand force to the outer part 22.

[0060] Based on the above implementation plan, see Figures 3 to 7 A slot 14 is provided at the open end of the housing 1. Corresponding to the slot 14, a clamping plate 24 is provided on the inner part 21 of the movable assembly 2. The clamping plate 24 is fixedly connected to the inner part 21. In the initial state of the control assembly, the clamping plate 24 is clamped in the slot 14.

[0061] By engaging the card plate 24 with the card slot 14, the card slot 14 is used to limit the lateral side and upper end surface of the card plate 24. Without intentional application of external force, the card plate 24 is limited, thereby preventing the movable component 2 from moving, thereby ensuring that the control component is in a normal isolation state for the liquid passage.

[0062] On the basis of the above-mentioned embodiment, a combination structure of a chute and a slider is further provided between the housing 1 and the movable component 2. The chute 15 is provided on the wall of the chamber 11, and the chute 15 is provided in the longitudinal direction, with one end of the chute 15 extending to the open end of the housing 1. A slider 25 is fixedly provided on the inner component 21, and the slider 25 is provided corresponding to the chute 15. The slider 25 is made of an elastic material and is provided in an inclined shape, with its lower end fixedly connected to the outer wall of the inner component 21 and its upper end inclined away from the inner component 21; in the initial state of the control component, the slider 25 is located outside the chute 15, and the upper edge of the slider 25 is against the inner wall of the chamber 11.

[0063] This structure improves the stability of the inner member 21 in its initial state by the contact force between the slider 25 and the inner wall of the chamber 11. When the inner member 21 is required to seal the second passage 13, the inner member 21 is first rotated to allow the slider 25 to enter the chute 15, and then pulled to slide the inner member 21 toward the outside of the housing 1.

[0064] Based on the above embodiment, a plurality of ridges or bumps can be provided on the wall of the chamber 11 corresponding to the position of the slider 25 in the initial state. The ridges or bumps are located above the slider 25 and abut against the upper surface of the slider 25. This structure can further restrict the movement of the slider 25 in the initial state, so that it can only move longitudinally after rotating into the chute 15.

[0065] On the basis of the above embodiment, the card slot 14 is an arc-shaped slot, the arc axis of which is coaxial with the chamber 11; the slide 15 is connected to the inside of the card slot 14; the card plate 24 is an inclined plate body with a shape similar to the slider 25, and the card plate 24 is symmetrically arranged on both sides of the inner part 21. Figure 4 With the direction as a reference, the lower end of the clamping plate 24 is fixedly connected to the inner member 21, and the upper end is tilted away from the inner member 21. When unloaded, the distance between the upper edge of the slider 25 and the axis of the inner member 21 is greater than the distance between the upper edge of the clamping plate 24 and the axis of the inner member 21. In other words, the slider 25 can be expanded laterally to a greater extent.

[0066] When the movable component 2 is in the initial state, the card plate 24 is located at a position where the card slot 14 is away from the slide 15. By rotating the movable component 2, the card plate 24 and the slider 25 both enter the slide 15, so that the movable component 2 can be pulled. As the movable component 2 is pulled, the card plate 24 is pulled out from the open end of the shell 1, and the slider 25 enters the position of the card slot 14. Because the slider 25 is wider than the card plate 24 after the elastic deformation is restored, it will rest on the top of the card slot 14, making it impossible for the movable component 2 to be pulled out further. At this time, the chamber 11 is already connected to the first channel 12 and the second channel 13, and the user can mix the liquids on both sides.

[0067] Based on the above implementation scheme, a baffle 26 is further provided on the movable component 2. The baffle 26 is located at the connection between the inner component 21 and the outer component 22. The baffle 26 is against the outer surface of the open end of the shell 1. The baffle 26 mainly prevents the inner component 21 from moving downward.

[0068] Building on the above-mentioned embodiment, a positioning block is provided on the underside of the baffle 26. A positioning slot is provided on the upper end surface of the housing 1 corresponding to the positioning block. A breakable structure is provided between the positioning block and the baffle 26. In the initial state, the positioning block is embedded in the positioning slot. This positioning block prevents the movable assembly 2 from rotating easily. Only during use, when a person applies external force, will the positioning block and baffle 26 break, allowing the movable assembly 2 to rotate.
