According to the food packaging bag capable of being secondarily sealed, the first plastic strip and the second plastic strip are arranged on the front side and the rear side of the packaging bag body correspondingly, and the plastic clamping frame and the clamping groove are arranged between the second plastic strip and the first plastic strip, so that the packaging bag body can continue to achieve the sealing effect through cooperation after a sealing mechanism fails; and secondly, the first rubber strip and the second rubber strip are arranged between the first plastic strip and the second plastic strip in a staggered mode, so that when the packaging bag body is sealed through the first plastic strip and the second plastic strip, the sealing effect can be improved through staggered extrusion of the first rubber strip and the second rubber strip.

Description

Technical Field

[0001] The utility model relates to the technical field of food packaging bags, in particular to a food packaging bag that can be sealed twice. Background Art

[0002] In order to ensure the sealing and convenience of subsequent actual use, food packaging bags are usually sealed with a sealing strip on the basis of thermoplastic sealing to facilitate the subsequent repeated sealing and use of the food packaging bags. Although the sealing strip is convenient for subsequent repeated sealing and use, it is inevitable that the sealing strip will also wear and deform during repeated use, resulting in the sealing effect of the food packaging bag becoming worse or even unable to continue to seal. In order to avoid such problems, a food packaging bag with secondary seals is proposed to solve the existing problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a food packaging bag that can be re-sealed, which solves the problem that the food packaging bag cannot be subsequently sealed after the sealing strip fails.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a secondary sealable food packaging bag, comprising a packaging bag body and a sealing mechanism, the sealing mechanism being arranged inside the packaging bag body, the front and rear sides of the packaging bag body being fixedly connected to a first plastic strip and a second plastic strip, respectively, both sides of the rear side of the second plastic strip being fixedly connected to a sliding sleeve, the interior of the sliding sleeve being slidably connected to a plastic card rack, the front side of the inner cavity of the plastic card rack being fixedly connected to a plastic card block, and the front side of the first plastic strip being provided with a card slot for use with the plastic card block.

[0005] Preferably, a plurality of first rubber strips are fixedly provided in a vertically equidistant array on the rear side of the first plastic strip, and a plurality of second rubber strips used in conjunction with the first rubber strips are fixedly provided in a vertically equidistant array on the front side of the second plastic strip.

[0006] Preferably, the sealing mechanism includes a self-sealing convex strip, which is fixedly arranged on the front side of the inner cavity of the packaging bag body, and a self-sealing concave strip used in conjunction with the self-sealing convex strip is fixedly connected to the rear side of the inner cavity of the packaging bag body.

[0007] Preferably, a paddle is fixedly connected to the front side of the plastic card holder.

[0008] Preferably, a cutting guide opening is opened on one side of the packaging bag body. Beneficial effects

[0009] The present invention provides a food packaging bag capable of secondary sealing. Compared with existing technologies, the present invention has the following advantages: by disposing a first plastic strip and a second plastic strip on the front and rear sides of the packaging bag body, respectively, and disposing a plastic card frame, a plastic card block, and a card slot between the second plastic strip and the first plastic strip, the packaging bag body can continue to achieve a sealing effect through the above-mentioned cooperation after the sealing mechanism fails. Secondly, by staggering the first and second rubber strips between the first and second plastic strips, the first and second rubber strips can be further squeezed when the first and second plastic strips seal the packaging bag body, thereby further improving the sealing effect.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1-4 The utility model provides a technical solution: a food packaging bag that can be sealed twice, including a packaging bag body 1 and a sealing mechanism 2, the sealing mechanism 2 is arranged inside the packaging bag body 1, the sealing mechanism 2 includes a self-sealing convex strip 21, the self-sealing convex strip 21 is fixedly arranged on the front side of the inner cavity of the packaging bag body 1, and the rear side of the inner cavity of the packaging bag body 1 is fixedly connected with a self-sealing concave strip 22 used in conjunction with the self-sealing convex strip 21, and a shearing guide port 11 is opened on one side of the packaging bag body 1.

[0017] Furthermore, in order to facilitate the sealing of the packaging bag body 1, the front and rear sides of the packaging bag body 1 are respectively fixedly connected with the first plastic strip 3 and the second plastic strip 4, and the two sides of the rear side of the second plastic strip 4 are fixedly connected with the sliding sleeve 9, the interior of the sliding sleeve 9 is slidably connected with a plastic card rack 5, and the front side of the inner cavity of the plastic card rack 5 is fixedly connected with a plastic card block 12. The front side of the first plastic strip 3 is provided with a card slot 6 for matching with the plastic card block 12, and the front side of the plastic card rack 5 is fixedly connected with a pick 10.

[0018] Furthermore, in order to improve the sealing effect of the packaging bag body 1, a plurality of first rubber strips 7 are fixedly provided in a vertically equidistant array on the rear side of the first plastic strip 3, and a plurality of second rubber strips 8 used in conjunction with the first rubber strips 7 are fixedly provided in a vertically equidistant array on the front side of the second plastic strip 4.

[0019] During use, the first plastic strip 3 and the second plastic strip 4 are fitted together to seal the packaging bag body 1, and then the plastic card frame 5 is slid downward to cause the plastic card frame 5 to gather and limit the first plastic strip 3 and the second plastic strip 4. When the plastic card frame 5 is pushed to the downward limit, it drives the plastic card block 12 to elastically engage and limit the card slot 6. When the first plastic strip 3 and the second plastic strip 4 are gathered together to seal the packaging bag body 1, the first rubber strip 7 and the second rubber strip 8 will interlace with each other to squeeze and seal the packaging bag body 1.
