[0002] Plastic bags are bags used to package various items and are widely used in daily life and industrial production. In people's daily life, when food is packed or stored, it is necessary to place the food in a plastic bag for storage. When the food is placed in a plastic bag, it needs to be sealed to prevent the food from contacting the outside air and deteriorating. When the existing plastic bags are sealed, it is easy for the buckle position to release the restriction when the plastic bag is squeezed from the outside, so that the food inside is exposed to the outside air. When placing multiple food plastic bags, the air inside a single bag makes the bag too large, and the air inside the bag cannot be discharged, affecting the storage space between the food plastic bags. To this end, we propose a food plastic bag that is easy to seal. Utility Model Content

[0017] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.
[0018] like Figure 1-3 As shown, the utility model is a food plastic bag that is easy to seal, comprising a plastic bag body 1, wherein the outer wall of the plastic bag body 1 is provided with a protective layer 11, wherein the protective layer 11 is arranged around the periphery and bottom of the plastic bag body 1, and the protective layer 11 is made of polyester fiber material. By providing the polyester fiber protective layer on the outer wall of the plastic bag body 1, the surface of the plastic bag body 1 is effectively prevented from being worn during storage, thereby increasing the wear resistance of the plastic bag body.
[0019] A reinforcement layer 12 is provided at the bottom of the plastic bag body 1. The high-strength PE fiber reinforcement layer 12 provided at the bottom of the plastic bag body 1 can prevent the plastic bag body 1 from being pierced by sharp points of food when the plastic bag body 1 is stored, causing the food to fall to the ground and be contaminated, thereby increasing the strength of the plastic bag body 1 and greatly improving the service life of the plastic bag body 1.
[0020] A convex strip 2 is fixedly provided around the upper opening of the plastic bag body 1, and a convex edge is provided at the bottom of the convex strip 2. A clamping head 21 is provided on the inner wall of the convex strip 2 on one side, and a groove 22 is provided on the inner wall of the convex strip 2 on the other side. When the food in the plastic bag body 1 needs to be sealed, the clamping head 21 and the groove 22 are matched, and the clamping head 21 is slidably engaged with the groove 22. The clamping heads 21 on both sides are engaged with the grooves 22, which can complete the sealing work of the food plastic bag and prevent the food from being exposed to the outside air and deteriorating.
[0021] The convex strip 2 is slidably connected to the buckle strip 3, and a notch 31 is provided in the buckle strip 3. An inward convex track 32 is provided on the inner wall of the buckle strip 3, and the convex track 32 matches the convex edge at the bottom of the convex strip 2. The buckle strip 3 is slidably connected to the convex strip 2 through the notch 31. By placing the notch 31 of the buckle strip 3 on the side of the convex strip 2, the convex track 32 and the convex edge at the bottom of the convex strip 2 are slidably arranged, so that the buckle strip 3 can be slidably engaged above the convex strip 2, and then after the plastic bag is sealed, the sealing port can be further sealed to prevent the food inside the plastic bag body 1 from being squeezed to discharge gas outward, and the clamping head 21 and the groove 22 that have completed the restriction can be easily released to prevent the food from contacting the external air and ensure the sealing effect.
[0022] The outer wall of the plastic bag body 1 is connected to a vent 4, and the vent 4 includes a sealing seat 41. One side of the sealing seat 41 is connected to the inside of the plastic bag body 1. A threaded rod 42 is fixedly provided on the outside of the sealing seat 41. The outer sleeve of the threaded rod 42 is connected to a screw cap 43. The inside of the threaded rod 42 is connected to the sealing seat 41 and extends to the inside of the plastic bag body 1. The insides of the sealing seat 41 and the threaded rod 42 are both connected to the inside of the plastic bag body 1, and the sealing seat 41 and the threaded rod 42 are integrated. The sealing seat 41 is fixedly installed on the side of the plastic bag body 1. When the inside of the plastic bag body 1 begins to swell due to the heat of food, the internal gas can be quickly discharged to the outside by rotating the screw cap 43, and the vent 4 is sealed again by rotating the screw cap 42. On the one hand, the possibility of the plastic bag bursting due to bloating can be avoided, and on the other hand, the space occupied by the plastic bag can be reduced, so that multiple plastic bags for food can be stored in the same space.
[0023] Working principle:
[0024] When the food plastic bag is easy to seal, food is placed inside the plastic bag body 1, and the clamping head 21 is squeezed to be embedded in the groove 22 to complete the sealing. At this time, the buckle strip 3 is slid over the convex strip 2 to further restrict the sealing opening to prevent the sealing opening from being released. At this time, the screw cap 43 is rotated to take it out, and the plastic bag is squeezed to discharge the air inside the plastic bag from the exhaust port 4 to reduce the volume of the plastic bag. After the exhaust is completed, the screw cap 43 is rotated and sealed on the threaded rod 42.
[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
