Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a butterfly valve packaging bag. Background Art

[0002] Butterfly valve packaging bags are packaging bags with a butterfly valve on one side of the bag body. They are generally used to hold liquids so that the liquid contents can be discharged through the butterfly valve. Users only need to turn the butterfly valve to open it. They are suitable for various situations where liquids need to be quickly filled and discharged. For this reason, the butterfly valve packaging bag itself often needs to use a composite film material with good sealing, barrier and durability, and the butterfly valve is connected to the packaging bag to keep it airtight.

[0003] In the prior art, since the butterfly valve is attached to one side of the bag body and extends outward, the center of gravity of the butterfly valve packaging bag is biased to one side, and the butterfly valve packaging bag is easy to tip over and has poor stability. Even though many butterfly packaging bags adopt a self-supporting packaging bag structure, that is, using the stretched bag bottom to horizontally support the bag body, they are still easily affected by external factors and collapse, causing inconvenience. For example, when commodities using butterfly valve packaging bags are displayed together, it is easy for one butterfly valve packaging bag to be unstable, and then the butterfly valve packaging bags arranged next to it will be pressed against and knocked over. During transportation and storage, the tipping of the butterfly valve packaging bag is also easy to fall to some positions that will cause damage to the bag body, bringing adverse effects.

[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the utility model is not limited to these embodiments.

[0027] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not very relevant are omitted.

[0028] Reference Figure 1 As shown, an embodiment of the utility model provides a butterfly valve packaging bag, which includes a bag body 1, a butterfly valve 2 and an auxiliary support portion 3.

[0029] Combination Figure 1 and Figure 2As shown, the bag body 1 includes a front side 11 and a back side 12. The front side 11 and the back side 12 of the bag body 1 are fitted together to form an internal accommodation space of the bag body 1. An opening is formed on the top of the bag body 1, which is a conventional packaging bag packaging and top opening method. The butterfly valve 2 is connected to the front side 11 of the bag body 1 and extends outward from the front side 11 of the bag body 1. Figure 3 As shown, a buckle groove 121 with a buckle opening facing the inner side of the bag body 1 is provided on the back side 12 of the bag body 1 .

[0030] The auxiliary support part 3 includes a connecting rod 31, a supporting rod 32 and an extension rod 33. The head end of the connecting rod 31 is rotatably connected to the housing 21 of the butterfly valve 2. The end of the connecting rod 31 is rotatably connected to the head end of the supporting rod 32. The supporting rod 32 is used to support the butterfly valve 2 through the connecting rod 31. The extension rod 33 is fixed to the end of the supporting rod 32. Figure 3 As shown, the extension rod 33 can be inserted into the buckle opening of the buckle groove 121 and fixed to close the opening of the bag body 1.

[0031] The auxiliary support part 3 is designed to be extended in the butterfly valve packaging bag. When in use, the auxiliary support part 3 of the butterfly valve packaging bag adjusts the placement angle of the auxiliary support part 3 by rotating the connecting rod 31 and the supporting rod 32, so that the supporting rod 32 is located on the bearing surface of the bag body 1, that is, the same plane as the contact with the bottom of the bag body 1. The supporting rod 32 forms a wider bottom base, which is forced upward by the connecting rod 31 to press against the outer shell 21 of the butterfly valve 2, so that the butterfly valve 2 can obtain a supporting force from bottom to top, even if the butterfly valve packaging The center of gravity of the bag is shifted under the influence of the extended butterfly valve 2, and the auxiliary support part 3 can be stretched and adjusted to assist the bag body 1 to remain self-standing from the side, thereby improving the standing stability of the butterfly valve packaging bag and preventing the butterfly valve packaging bag from being easily collapsed by external influences. It is suitable for a large number of butterfly valve packaging bags to be displayed side by side. Each butterfly valve packaging bag can be stacked on the support rod 32 of the adjacent butterfly valve packaging bag in sequence, and the other butterfly valve packaging bags pressed on the support rod 32 play the role of heavy objects pressing and further preventing the butterfly valve packaging bags from collapsing one after another.

[0032] When the user needs to open the butterfly valve 2 to take out the contents of the bag 1, he can place a cup or other container prepared to hold the contents on the support rod 32. The support rod 32 can act as a coaster to protect the bearing surface. In the auxiliary support part 3, since the extension rod 33 is fixed to the end of the support rod 32, when the support rod 32 is placed on the bearing surface, the extension rod 33 acts as a counterweight at the end of the support rod 32, so that the support rod 32 is placed more stably, which can more effectively prevent the butterfly valve packaging bag from sliding or tipping over when subjected to external forces. In addition, referring to Figure 2 and Figure 3As shown, by rotating the connecting rod 31 and the supporting rod 32, the auxiliary supporting portion 3 can be deformed into a structure that is close to the front side 11 of the bag body 1 and extends toward the buckle groove 121, and the extension rod 33 at the rear is inserted into the buckle opening of the buckle groove 121 and fixed, and a part of the bag body 1 between the buckle groove 121 and the extension rod 33 is clamped, thereby playing the role of closing the opening of the bag body 1, further improving the sealing performance of the butterfly valve packaging bag, and facilitating the opening of the butterfly valve packaging bag to replenish the contents.

[0033] The rotatable connecting rod 31 and the supporting rod 32 can adapt to different placement environments and needs, allowing the self-standing angle of the packaging bag to be adjusted as needed so that it can maintain a stable self-standing state in different scenarios, which not only increases the flexibility and adaptability of the packaging bag, but also improves the user experience.

[0034] In addition, the auxiliary support part 3 can be used as a carrying structure of the butterfly valve packaging bag. The user can directly lift the extension rod 33 to lift the entire butterfly valve packaging bag. The rod body structure of the extension rod 33 can provide a larger contact area and a good hand touch, which is convenient for the placement and transportation of the butterfly valve packaging bag. The butterfly valve packaging bag does not need to have additional lifting holes, which saves working procedures and reduces production costs.

[0035] In this embodiment, the bag body 1 of the butterfly valve packaging bag adopts a self-supporting structure. Figure 2 As shown, the expanded bag bottom can be used to increase the width of the bag body 1 relative to its bearing surface, thereby horizontally supporting the bag body to stand on its own, further enhancing the standing stability of the bag body 1.

[0036] The specific assembly structure of the auxiliary support part 3 is as follows: connecting holes are provided on opposite sides of the shell 21 of the butterfly valve 2, and there are two connecting rods 31, and the head ends of the two connecting rods 31 are respectively detachably inserted into the connecting holes on the corresponding sides. The two connecting rods 31 correspond to the left and right sides of the shell 21 of the butterfly valve 2, providing a balanced supporting force for the butterfly valve 2, and the detachable assembly method can provide convenience for the user to use or remove the auxiliary support part 3 according to their own needs.

[0037] Similarly, there are two support rods 32, and the ends of the two connecting rods 31 are respectively connected to the head ends of the corresponding support rods 32 through hinges 34, and the ends of the two support rods 32 are both welded and fixed on the same side of the extension rod 33. The support rods 32 and the connecting rods 31 can also be made in an integrated manner, which is conducive to reducing production costs and improving efficiency.

[0038] Based on the butterfly valve 2 and the auxiliary support part 3 on the butterfly valve packaging bag, various specific implementations can be adopted. According to the different height positions of the butterfly valve 2 on the bag body 1, the auxiliary support part 3 is deformed to facilitate adaptive adjustment, so that the support rod 32 can be stably placed on the bearing surface and provide supporting force to the outer shell 21 of the butterfly valve 2 through the connecting rod 31, and the extension rod 33 can be inserted into the buckle groove 121. The connecting rod 31 and the support rod 32 are retractable rods. By adjusting the length of the connecting rod 31 and the support rod 32, the auxiliary support part 3 can be more easily adjusted to achieve the above effects.

[0039] Furthermore, a non-slip pad is connected to the bottom of the support rod 32, so that when placed on a smooth bearing surface, the support rod 32 is not likely to slide due to a sufficiently large friction force, thereby avoiding tipping.

[0040] In order to facilitate the bag body 1 to load the contents and maintain the sealing after the opening is closed, the bag body 1 is provided with two zipper seals 13 in sequence from top to bottom near the bag opening, and the buckle groove 121 is located below the two zipper seals 13.

[0041] In line with the zipper seal 13 , the extension rod 33 is flush with the bottom edge of the bag body 1 , and the length of the extension rod 33 is not less than the length of the zipper seal 13 .

[0042] Since the excessive weight of the butterfly valve 2 is a factor that affects the center of gravity shift and tipping of the bag body 1 after it stands on its own, the butterfly valve 2 should be made of lightweight materials as much as possible. In addition, the connecting rod 31, the support rod 32 and the extension rod 33 in the auxiliary support part 3 should also be the same. Considering that the contents should be made of corrosion-resistant materials, in this embodiment, the connecting rod 31, the support rod 32 and the extension rod 33 are polypropylene plastic rod bodies, and the outer shell 21 of the butterfly valve 2 is a polypropylene plastic valve body, which has good thermoplasticity and elasticity. The use of plastic has the advantages of mature general technology, easy implementation and low cost.

[0043] The front side 11 of the bag body 1 and the back side 12 of the bag body 1 are both composite films including polyester aluminum-plated film, polyamide film and polypropylene film. The composite material combines the high strength of the polyester aluminum-plated film and the wear resistance of the polyamide film, so that the bag body has excellent impact resistance and wear resistance, excellent tensile strength and wear resistance, and protects the safety and integrity of the butterfly valve packaging bag during transportation and storage.

[0045] The above is only a specific implementation of the present application.
