Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping bags, in particular to a multi-sealed polymer fresh-keeping bag. Background Art

[0002] Fresh-keeping bags are a common household item used to store and maintain the freshness of food. They are usually made of food-grade PP and PE materials. When using them, seal the food or other items in the fresh-keeping bag and try to expel the air in the bag. Then use the sealing device on the bag to seal the mouth to ensure that the fresh-keeping bag is isolated from the outside world, thereby preventing air, moisture and bacteria from entering the bag, reducing the oxidation of items in the bag and bacterial growth, maintaining the freshness of food, and extending the shelf life of items. It can also prevent the spread of odors, prevent leakage of liquids and food, and ensure that the taste of food is not affected. It has leak-proof, moisture-proof and sealing properties.

[0003] The existing patent (Announcement No.: CN220518969U) discloses a multi-sealed fresh-keeping bag, which realizes double sealing by buckling the first card slot and the wavy second card strip, and buckling the second card slot and the long first card strip; and the wavy second card strip can better adapt to the irregular or curved surface of the opening, provide a better sealing effect, and can also improve the strength of the opening to a certain extent, making it not easy to break; the first ridge and the second ridge set between the first card strip can further improve the strength of the tearing part of the bag body, and when the bag body is sealed, the first ridge and the second ridge abut against each other, thereby further strengthening the sealing of the fresh-keeping bag. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:

[0004] Although the fresh-keeping bag can achieve a good sealing effect through a variety of sealing structures during use, dust and the like are easily accumulated on the top of the sealing structure during use. Although blocked by the sealing structure, the dust is easy to fall into the inside of the fresh-keeping bag once it is opened. Secondly, the handles are often separated to both sides during use. When the fresh-keeping bag is pulled, the weight of the handles is under the handles, which makes it easy for the user's hands to have marks, which is quite uncomfortable. Utility Model Content

[0005] In order to improve the above-mentioned problem that the main body of the fresh-keeping bag is easily contaminated by dust, thereby affecting the internal items and causing hand discomfort when pulling, the utility model provides a multi-sealed polymer fresh-keeping bag.

[0010] Optionally, in the above-mentioned multi-sealed polymer fresh-keeping bag, sealing structures are symmetrically distributed on both sides of the interior of the fresh-keeping bag body, and there are three groups of sealing structures. The sealing structures are composed of buckles and slots, and the buckles and slots are integrated with the fresh-keeping bag body.

[0011] Through the above technical solution, it is convenient to improve the sealing effect through multiple sealing structures to ensure subsequent use.

[0012] Optionally, in the above-mentioned multi-sealed polymer fresh-keeping bag, the first engaging blocks are symmetrically distributed on the front side of the handle, the height of the first engaging blocks is lower than the top height of the fresh-keeping bag body, and the first engaging blocks are engaged with the auxiliary blocks.

[0013] Through the above technical solution, it is convenient to complete the work of limiting and fixing the sealing belt through the cooperation between the first engaging block and the auxiliary block.

[0014] Optionally, in the above-mentioned multi-sealed polymer fresh-keeping bag, the second engaging blocks are symmetrically distributed on both sides of the handle, the second engaging blocks are engaged with each other, the handle is integrally installed with the fixing block, and the fixing block is integrally installed with the fresh-keeping bag body.

[0015] Through the above technical solution, the second engaging block can cooperate with the handle to fit the handle, making it easier to lift the handle.

[0016] Optionally, in the above-mentioned multi-sealed polymer fresh-keeping bag, the center line of the restraint belt and the center line of the handle are above the same horizontal line, the restraint belt and the handle are installed as one piece, and Velcro is symmetrically distributed on both sides of the restraint belt, and the Velcro is adsorbed to the Velcro on the other side.

[0017] Through the above technical solution, it is convenient to wrap the top of the handle by cooperating with the binding belt and the handle, thereby improving the comfort of using the handle.

[0018] Optionally, in the above-mentioned multi-sealed polymer fresh-keeping bag, the connecting block is integrally installed with the fresh-keeping bag body, the connecting block is integrally installed with the sealing belt, and the length of the sealing belt is consistent with the length of the auxiliary block.

[0019] Through the above technical solution, the top of the fresh-keeping bag body can be sealed by cooperating with the sealing belt and the auxiliary block to prevent dust from entering the inside when the fresh-keeping bag is in use.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] By arranging a connecting block and a sealing belt on the outside of the fresh-keeping bag body, the sealing belt can seal the outlet of the fresh-keeping bag body when the fresh-keeping bag body is stationary for a long time, so as to prevent dust and other debris from falling on the outside of the fresh-keeping bag body and entering the inside thereof, and the sealing belt can be quickly spliced ​​by using an auxiliary block, so that disassembly and installation are convenient, thereby improving the convenience of use;

[0022] By arranging Velcro and a strap above the handle, the strap is used to wrap the handle during use, so that when the handle is pulled up, the hand grasps the strap without direct contact with the handle, thereby avoiding the weight of the handle hanging above the hand, avoiding strangulation marks on the hand, and improving the comfort of use of the fresh-keeping bag body.
