Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food packaging bag technology, specifically relating to a pet food packaging bag. Background Technology
[0002] Packaging bags are bags or boxes used to package various goods, making them easy to store during transportation or use. They are widely used in daily life and industrial production. The applications of packaging bags are very broad, covering clothing, food, housing, and transportation, including pet food.
[0003] Pet food packaging not only affects the preservation quality of the food but also influences consumers' purchasing decisions and pet safety. Freeze-dried food, a high-end category of pet food using "low-temperature freeze-drying" as its core technology, has become increasingly popular among pet owners in recent years due to its characteristics such as "complete nutrient retention, crisp texture, and easy absorption." However, freeze-dried food is highly hygroscopic, requiring special attention to moisture and oxygen prevention during storage.
[0004] However, existing pet food packaging bags typically use self-sealing bags for sealing. This sealing method leaves some oxygen in the packaging bag after each use, especially when the pet food is almost finished. Each time it is opened, a large amount of air enters, and even after sealing, a lot of air remains, making freeze-dried pet food prone to moisture absorption, spoilage, and nutrient loss, resulting in losses for users.
[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a pet food packaging bag.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0007] The purpose of this utility model is to provide a pet food packaging bag that can solve the problem in the prior art that a large amount of air remains after each use of pet food packaging bags, increasing the probability of pet food spoilage.
[0008] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0009] A pet food packaging bag includes: a food storage bag, a sealing structure, and multiple control structures.
[0010] The food storage bag is equipped with multiple sets of limiting components.
[0011] The sealing structure is slidably disposed inside the food storage bag. The sealing structure includes an upper cap, multiple sealing airbags, and one-way exhaust valves. The upper cap has multiple grooves that match the sealing airbags, and the sealing airbags are fixed within these grooves and filled with air. The multiple one-way exhaust valves are all installed at the bottom of the upper cap.
[0012] Multiple control structures are installed on the upper cover. Each control structure includes a control push rod and a fixing component installed on the control push rod. The control push rod is threadedly connected to the upper cover, and the fixing component is used to fix the upper cover, making it less likely for the upper cover to slide up and down, thereby improving the sealing effect.
[0013] In one or more embodiments of this utility model, the limiting component includes: a tight-fitting sleeve and a limiting post. The tight-fitting sleeve is installed on the inner wall of the food storage bag; the limiting post is fixed to the tight-fitting sleeve, and the limiting post is made of rubber. The tight-fitting sleeve limits the upper cover, making it less likely to shift when the upper cover moves up and down. The limiting post ensures an interference fit between the tight-fitting sleeve and the upper cover, which not only improves the sealing performance but also prevents the upper cover from shifting inside the food storage bag.
[0014] In one or more embodiments of this utility model, a pair of lifting handles are fixedly installed on the upper cover. The pair of lifting handles are symmetrically arranged along the central axis of the upper cover, which is used to facilitate the user to lift the upper cover and thus facilitate the movement of the upper cover.
[0015] In one or more embodiments of this utility model, the upper cover is provided with multiple lifting cavities, and each of the multiple lifting cavities is slidably provided with a pressing block. The pressing block squeezes the sealing airbag, causing the sealing airbag to deform, so that one side of the sealing airbag can be tightly attached to the food storage bag, increasing the sealing performance and making it difficult for air to come into contact with the pet food.
[0016] In one or more embodiments of this utility model, a rotating block is fixedly installed on the end of the control push rod away from the upper cover, which is used to facilitate the rotation of the control push rod and make it easier for the user to operate.
[0017] In one or more embodiments of this utility model, the fixing component includes: an insert rod, a rotating push rod, and a pressing and fastening block; the insert rod is inserted into one end of the control push rod, and a threaded groove is formed on the insert rod. The rotating push rod is threadedly connected to the insert rod, and the pressing and fastening block is fixedly installed on one end of the rotating push rod. The rotation of the rotating push rod can drive the pressing and fastening block closer to the food storage bag until the pressing and fastening block is completely adhered to the inner wall of the food storage bag, thereby increasing friction and making the top cover less prone to moving up and down, thus providing an auxiliary fixing effect.
[0018] In one or more embodiments of this utility model, a fixed bearing is fixedly connected between the control push rod and the insertion rod, making it difficult for the insertion rod to fall off, and the rotation of the insertion rod is not easily affected by the control push rod.
[0019] In one or more embodiments of this utility model, the side of the pressing and fastening block away from the rotating push rod is roughened to increase friction, making the pressing and fastening block less likely to move, thereby assisting in fixing the upper cover.
[0020] Compared with the prior art, this utility model, through the setting of the corresponding mechanism, makes it difficult for air to remain in the pet food packaging bag, thereby making the pet food less susceptible to moisture and spoilage, and less likely to cause nutrient loss, thus reducing losses for users.

Detailed Implementation
[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0032] like Figures 1 to 7 As shown, a pet food packaging bag in one embodiment of the present invention includes: a food storage bag 1, a sealing structure 2, and multiple control structures 3.
[0033] like Figures 1 to 7 As shown, multiple sets of limiting components 101 are installed on the food storage bag 1. A sealing structure 2 is slidably disposed inside the food storage bag 1. The sealing structure 2 includes an upper sealing cover 201, multiple sealing airbags 202, and one-way exhaust valves 203. Multiple grooves matching the sealing airbags 202 are carved into the upper sealing cover 201, and the sealing airbags 202 are fixed within these grooves and filled with air. Multiple one-way exhaust valves 203 are installed at the bottom of the upper sealing cover 201. Multiple control structures 3 are installed on the upper sealing cover 201. Each control structure 3 includes a control push rod 301 and a fixing component 303 installed on the control push rod 301. The control push rod 301 is threadedly connected to the upper sealing cover 201, and the fixing component 303 is used to fix the upper sealing cover 201, preventing it from sliding up and down and improving the sealing effect.
[0034] In use, the upper cover 201 is placed inside the food storage bag 1 and then pressed on top of the pet food to expel all the air from the food storage bag 1, thus preventing the pet food from getting damp or spoiling. Then, by rotating the control push rod 301, the sealing airbag 202 is pressed down, causing the sealing airbag 202 to deform and fit against the food storage bag 1, thereby blocking the entry of air and improving the sealing effect. Finally, the fixing component 303 is used to further fix the upper cover 201, making it difficult for the sealing airbag 202 to move up and down inside the food storage bag 1, thus preventing air from entering.
[0035] like Figure 1 and Figure 7 As shown, the limiting component 101 includes a tight-fitting sleeve 103 and a limiting post 102. The tight-fitting sleeve 103 is installed on the inner wall of the food storage bag 1; the limiting post 102 is fixed to the tight-fitting sleeve 103, and the limiting post 102 is made of rubber. The tight-fitting sleeve 103 limits the upper cover 201, making it less likely to deviate when the upper cover 201 moves up and down. The limiting post 102 is used to ensure an interference fit between the tight-fitting sleeve 103 and the upper cover 201, which not only improves the sealing performance but also makes it less likely for the upper cover 201 to move inside the food storage bag 1.
[0036] like Figures 1 to 7 As shown, a pair of lifting handles 204 are fixedly installed on the upper cover 201. The pair of lifting handles 204 are symmetrically arranged along the central axis of the upper cover 201 to facilitate the user to lift the upper cover 201 and thus facilitate the movement of the upper cover 201.
[0037] like Figures 1 to 5 As shown, the upper cover 201 has multiple lifting cavities 206, and each lifting cavity 206 has a sliding pressing block 205. The pressing block 205 compresses the sealing airbag 202, causing it to deform. This allows one side of the sealing airbag 202 to adhere tightly to the food storage bag 1, increasing the seal and preventing air from easily contacting the pet food.
[0038] like Figures 1 to 4 As shown, a rotating block 302 is fixedly installed on the end of the control push rod 301 away from the upper cover 201, which is used to facilitate the rotation of the control push rod 301 and make it easier for the user to operate.
[0039] like Figures 1 to 4 As shown, the fixing component 303 includes: an insertion rod 305, a rotating push rod 306, and a pressing and fastening block 307. The insertion rod 305 is inserted into one end of the control push rod 301, and a threaded groove is cut into the insertion rod 305. The rotating push rod 306 is threadedly connected to the insertion rod 305, and the pressing and fastening block 307 is fixedly installed on one end of the rotating push rod 306. The rotation of the rotating push rod 306 can drive the pressing and fastening block 307 to approach the food storage bag 1 until the pressing and fastening block 307 is completely adhered to the inner wall of the food storage bag 1, thereby increasing the friction and making it difficult for the upper cover 201 to move up and down, thus playing a role in auxiliary fixing.
[0040] A fixed bearing 304 is fixedly connected between the control push rod 301 and the insertion rod 305, making it difficult for the insertion rod 305 to fall off, and the rotation of the insertion rod 305 is not easily affected by the control push rod 301.
[0041] In addition, the side of the pressing and fastening block 307 away from the rotating push rod 306 is roughened to increase friction, making the pressing and fastening block 307 less likely to move, thereby helping to fix the upper cover 201.
[0042] The working principle is as follows: First, rotate multiple rotating push rods 306 so that the rotating push rods 306 no longer drive the pressing and sealing block 307 to stick to the inner wall of the food storage bag 1. Then, rotate the rotating block 302, which drives the control push rod 301 to rotate, thereby raising the control push rod 301 and no longer pressing down the pressing block 205. At this time, one side of the sealing airbag 202 will no longer stick to the food storage bag 1. Pulling a pair of lifting handles 204 will raise and open the upper cover 201, and then the user can take out the pet food in the food storage bag 1.
[0043] After the pet food is removed, the upper cover 201 is placed into the food storage bag 1. The sealing performance is improved by the interference fit of multiple limiting bars 102. As the upper cover 201 is lowered, the air inside the food storage bag 1 can be discharged outward through multiple one-way exhaust valves 203. Finally, the bottom surface of the upper cover 201 is flush with the pet food to remove all the air. Then, the rotating block 302 is rotated to push the lower pressing block 205 downward to squeeze the sealing airbag 202. The sealing airbag 202 will deform after being squeezed, and then it can stick tightly to the food storage bag 1 to improve the sealing effect. Finally, the rotating push rod 306 is rotated to drive the pressing and sticking block 307 to stick tightly to the food storage bag 1 to increase the friction and make the upper cover 201 less likely to move.
[0044] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this disclosure.
