Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a cat food packaging bag that can be opened and sealed multiple times. Background Technology

[0002] Cat food packaging bags are made of various materials, commonly including plastic composites, paper composites, and biodegradable materials. Plastic composites are widely used due to their excellent moisture-proof, oxidation-proof, and sealing properties. Paper composites combine the environmental friendliness of paper with the protective properties of plastic. Biodegradable materials are an environmentally friendly option that has emerged in recent years, gradually decomposing in the natural environment. Among these, cat food packaging bags are mostly made of plastic composites. One of the main functions of cat food packaging bags is to protect cat food from moisture and oxidation, thereby extending its shelf life. High-quality packaging bags can effectively isolate external moisture and oxygen, maintaining the freshness and taste of the cat food. In addition, the design of cat food packaging bags usually focuses on the combination of practicality and aesthetics. The packaging will be printed with key information such as brand logo, product name, ingredient list, feeding instructions, and shelf life so that consumers can understand the product details. At the same time, the packaging colors and patterns are also designed according to the preferences of the target consumer group to attract consumers' attention.

[0003] However, common cat food packaging bags require the air to be released after being opened and sealed multiple times to feed the cat to prevent the cat food from getting damp. However, repeated squeezing can cause the sealing strip to deform, resulting in poor sealing. In addition, when there is a lot of cat food in the packaging bag, it is easy to slip off when the bag is squeezed by hand, which is not conducive to use. Therefore, there is still room for further improvement.

[0004] Therefore, we propose a resealable cat food packaging bag that can be opened multiple times to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a cat food packaging bag that can be opened and sealed multiple times, in order to solve the problem mentioned in the background art that common cat food packaging bags need to be opened and sealed multiple times during use to feed cats, and it is necessary to release the gas inside the packaging bag to prevent the cat food from getting damp. However, repeated squeezing will cause the sealing strip to deform, resulting in poor sealing. In addition, when there is a lot of cat food in the packaging bag, it is easy to slip off when the packaging bag is squeezed by hand, which is not conducive to use. Therefore, there is still room for further improvement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a resealable cat food packaging bag, comprising:

[0007] The first composite plastic has a connecting seat on its front side and its lower side is fixedly connected to the second composite plastic. The first composite plastic is symmetrical about the vertical central axis of the second composite plastic.

Moreover, the protective pads are symmetrical about the horizontal central axis of the sliding block.

[0016] Preferably, the sliding block is threadedly connected to the threaded rod, and the threaded rod is rotatably connected to the conical platform. A connecting ring is provided on the upper side of the sliding block. The sliding groove, sliding block, protective pad, threaded rod, conical platform, and connecting ring are arranged in a one-to-one correspondence between the sliding groove and the first composite plastic.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: The resealable cat food packaging bag has a filter screen that is slidably connected to the one-way exhaust valve through a groove, which facilitates the obstruction of cat food during exhaust and prevents cat food from clogging the one-way exhaust valve. The connecting column allows the limiting cylinder to slide and connect with the one-way exhaust valve, thereby limiting the filter screen and preventing it from accidentally sliding out of the one-way exhaust valve. The protective pad fits tightly against the inner wall of the sliding groove, making it easy to fix the sliding block inside the sliding groove. It is also convenient to wrap a rope around the outside of the connecting ring and then take out the packaging bag, avoiding breaking the cat food inside the packaging bag.

[0018] 1. The device is provided with a first composite plastic, a second composite plastic and a third composite plastic. The lower side of the first composite plastic is fixedly connected to the second composite plastic, and the side of the first composite plastic is fixedly connected to the third composite plastic.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 As shown, this utility model provides a technical solution: a cat food packaging bag that can be opened and sealed multiple times, including: a first composite plastic 1, a connecting seat 2, a one-way exhaust valve 3, a slot 4, a filter screen 5, a connecting column 6, a limiting cylinder 7, a second composite plastic 8, a third composite plastic 9, a sealing strip 10, an exhaust plate 11, an arc-shaped plastic plate 12, a sliding groove 13, a sliding block 14, a protective pad 15, a threaded rod 16, a conical platform 17, and a connecting ring 18.

[0031] Existing cat food packaging bags require the air to be released after multiple openings to feed the cat to prevent the cat food from getting damp. However, repeated squeezing can cause the sealing strip 10 to deform, resulting in poor sealing. In addition, when there is a lot of cat food in the packaging bag, it is easy for the bag to slip when squeezed by hand, which is not conducive to use. Therefore, there is still room for further improvement.

[0032] like Figure 1 and Figure 4As shown, the lower side of the first composite plastic 1 is fixedly connected to the second composite plastic 8, the side of the first composite plastic 1 is fixedly connected to the third composite plastic 9, and the third composite plastic 9 is fixedly connected to the first composite plastic 1. The first composite plastic 1 is symmetrical about the vertical central axis of the second composite plastic 8, and the third composite plastic 9 is symmetrical about the vertical central axis of the second composite plastic 8. Thus, they can be combined into a packaging bag for easy storage of cat food. In addition, a sealing strip 10 is provided on the upper inner side of the first composite plastic 1. The sealing strip 10 can seal the upper inner sides of the two first composite plastic 1s, thereby forming a sealed environment for easy storage of cat food.

[0033] It should be noted that, under normal circumstances, when venting the packaging bag, it is usually done by direct squeezing or bending and squeezing. However, this method is easy to damage the sealing strip 10 and is not conducive to repeated opening and closing.

[0034] like Figure 1 and Figure 3 As shown, an exhaust plate 11 is provided on the outer side of the first composite plastic 1, and an arc-shaped plastic plate 12 is provided on the inner side of the exhaust plate 11. The side of the arc-shaped plastic plate 12 is arc-shaped. The arc-shaped plastic plate 12 can also avoid damaging the first composite plastic 1 during movement, and has a certain protective function. When the exhaust plate 11 is moved up and down, the arc-shaped plastic plate 12 will fit tightly against the outer side of the first composite plastic 1, thereby venting the air in the packaging bag from the one-way exhaust valve 3, which plays a role in moisture prevention. Using the arc-shaped plastic plate 12 to vent the air in the packaging bag can also avoid damaging the sealing strip 10, which is beneficial for multiple openings.

[0035] like Figure 1 and Figure 2 As shown, a connecting seat 2 is provided on the lower front side of the first composite plastic 1. The first composite plastic 1 and the connecting seat 2 can be connected by adhesive. The one-way exhaust valve 3 can be connected to the first composite plastic 1 through the connecting seat 2. In addition, a groove 4 is opened inside the one-way exhaust valve 3 near the connecting seat 2, and the groove 4 is slidably connected to the filter screen 5. When the air inside the packaging bag is delivered from the connecting seat 2 to the one-way exhaust valve 3, the filter screen 5 can filter the air to prevent cat food from entering the one-way exhaust valve 3 and prevent the one-way exhaust valve 3 from being blocked. In addition, a connecting post 6 is provided on the front side of the one-way exhaust valve 3. The connecting post 6 and the limiting cylinder 7 are threadedly connected. After the connecting post 6 and the limiting cylinder 7 are threaded together, the limiting cylinder 7 is slidably connected to the one-way exhaust valve 3, so that the limiting cylinder 7 plays a limiting role in the filter screen 5, preventing the filter screen 5 from accidentally sliding out of the one-way exhaust valve 3, making it convenient to use.

[0036] like Figure 1 , Figure 4 and Figure 5As shown, the sliding groove 13 is located above the front side of the first composite plastic 1, and a sliding block 14 is slidably connected inside the sliding groove 13. Without limiting the sliding block 14, it can move freely within the sliding groove 13. One sliding groove 13 corresponds to two sliding blocks 14. After connecting both ends of the rope to the connecting ring 18 on the upper side of the sliding block 14, the threaded rod 16 is rotated. Since the threaded rod 16 is threadedly connected to the sliding block 14 and rotatably connected to the conical platform 17, and the side of the conical platform 17 is conical, and the inner side of the sliding block 14 is inclined, rotating the threaded rod 16 allows the conical platform 17 to approach the sliding block 14. When the conical platform 17 and the sliding block 14 are tightly fitted together, the threaded rod 16 is rotated, and the conical platform 17 will press the sliding block 14 outward. The outer side of the sliding block 14 is also inclined, and a protective pad 15 is provided on the outer side of the sliding block 14. Therefore, the protective pad 15 is tightly fitted with the inner wall of the sliding groove 13, which makes it easy to fix the sliding block 14 on the inner side of the sliding groove 13. This makes it easy to take out the first composite plastic 1 through the sliding groove 13, avoiding breaking the cat food in the packaging bag. In addition, the sliding groove 13, the sliding block 14, the protective pad 15, the threaded rod 16, the conical platform 17 and the connecting ring 18 correspond one-to-one with the first composite plastic 1, which makes it easy to take out the packaging bag from the front and back sides.
