Description

Technical Field

[0001] The utility model relates to the technical field of food bags, and more specifically to a moisture-proof food zipper bag with good sealing performance. Background Art

[0002] Food packaging bags are a type of packaging design. In order to preserve and store food in life, product packaging bags are produced. Food packaging bags refer to film containers that are in direct contact with food and are used to hold and protect food.

[0003] After the existing food packaging bags store food inside, in many cases there is usually a lot of food in the bag and it cannot be consumed all at once. Many food packaging bags will be installed with zippers inside the bags to achieve secondary sealing. However, the existing zippers are very small in size. When they are manually engaged, it is easy for some zippers to not be fully engaged and cause gaps, resulting in moisture inside the food packaging bag. A solution is proposed below to solve the above problem. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a moisture-proof food zipper bag with good sealing performance, which can achieve high sealing performance and high moisture resistance.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A moisture-proof food zipper bag with good sealing performance comprises a bag body with an open end, a clip chain for the open end of the bag body is fixedly connected to the inner side surface of the open end of the bag body, a clamp block for pressing and engaging the clip chain is slidably arranged at the open end of the bag body, the cross-section of the clamp block is N-shaped, and the inner side surface of the clamp block is symmetrically provided with card grooves adapted to the clip chain, the farthest distance between two card grooves is the same as the width after the clip chain is engaged, and a sealing part that plays a secondary sealing role is installed at the opening of the bag body.

[0007] Preferably, the sealing portion includes an extension bag and a metal sheet, the extension bag is in the form of a tube with both ends connected, one end of the extension bag is sleeved on the open end of the bag body and fixedly connected, the metal sheet is attached to the outer side surface of one end of the extension bag away from the bag body, and the length of the metal sheet is greater than the width of the extension bag.

[0008] Preferably, the metal sheet is an aluminum sheet with a width of 0.5 cm.

[0009] Preferably, slides are symmetrically arranged inside the extension bag, and slide grooves are provided on both sides of the clamping block corresponding to the slides, the slides are slidably arranged inside the slide grooves, and the slides are clamped with the slide grooves.

[0010] Preferably, the width of the extension bag is greater than the width of the bag body.

[0011] Preferably, the height of the bag body is 4 cm.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1. This solution uses a clamp block arranged at the opening of the bag to move and seal the clip chain, avoiding the problem of incomplete sealing when the clip chain is pressed manually, ensuring the sealing. At the same time, through the cooperation of the metal sheet and the extension bag, secondary sealing can be achieved, further improving the sealing effect and thus preventing moisture.

[0014] 2. The cooperation of the slide and the slide groove can prevent the clamp block and the clamp chain from separating, thus achieving a limiting effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Embodiment 1:

[0022] See also Figure 1-4 A moisture-proof food zipper bag with good sealing performance comprises a bag body 1 with an opening at one end, a clip chain 2 for the open end of the bag body 1 is fixedly connected to the inner side of the open end of the bag body 1, and a clamp block 3 for pressing and engaging the clip chain 2 is slidably provided at the open end of the bag body 1, the cross section of the clamp block 3 is N-shaped, and the inner side surface of the clamp block 3 is symmetrically provided with card slots 4 adapted to the clip chain 2, and the farthest distance between the two card slots 4 is the same as the width of the clip chain 2 after engagement.

[0023] A sealing part 5 that plays a secondary sealing role is installed at the opening of the bag body 1. The sealing part 5 includes an extension bag 6 and a metal sheet 7. The extension bag 6 is a tube-shaped tube connected at both ends. The height of the extension bag 6 is 4 cm. The width of the extension bag 6 is greater than the width of the bag body 1. One end of the extension bag 6 is sleeved on the open end of the bag body 1 and fixedly connected. The clamping block 3 is located inside the extension bag 6. Slides 8 are symmetrically arranged inside the extension bag 6. Slide grooves 9 are provided on both sides of the clamping block 3 corresponding to the slides 8. The slides 8 are slidably arranged inside the slide grooves 9, and the slides 8 and the slide grooves 9 are clamped. The cooperation between the slides 8 and the slide grooves 9 can prevent the clamping block 3 from falling off, thereby ensuring the sealing of the clamping block 3 to the clip chain 2. The metal sheet 7 is an aluminum sheet with a width of 0.5 cm. The metal sheet 7 is attached to the outer side of the end of the extension bag 6 away from the bag body 1, and the length of the metal sheet 7 is greater than the width of the extension bag 6.

[0024] Working principle:

[0025] When sealing, first slide the clamp block 3, which will drive the slot 4 to move, and the slot 4 will move along the axial direction of the clip chain 2. Since the farthest distance between the two slots 4 is the same as the width of the clip chain 2 after engagement, the slot 4 will press the clip chain 2 to complete the sealing, avoiding gaps caused by incomplete sealing due to manual pressing. At the same time, the width of the extension bag 6 is greater than the width of the bag body 1 to ensure that the clamp block 3 is completely moved from one end of the bag body 1 to the other end. After completing the sealing of the clip chain 2, rotate the metal sheet 7, which will drive the extension bag 6 to wrap around the metal sheet 7. When the metal sheet 7 is rotated to a certain position, the two ends of the metal sheet 7 extending out of the extension bag 6 are bent and pressed on the extension bag 6 to complete the self-sealing, avoid the extension bag 6 from spreading, and play a secondary sealing role, thereby preventing moisture.
