Description

Technical Field

[0001] This utility model relates to the field of resealable bag technology, and in particular to a drawstring plastic food resealable bag. Background Technology

[0002] Plastic food resealable bags are used to hold food, preventing it from being isolated from the outside air and thus preserving freshness, preventing moisture, dust, and oxidation, as well as facilitating categorized storage. Current technology uses single or double sealing strips to seal the bag opening. While this increases the bag's tightness, it requires pulling on the bag body or opening from both sides to remove the sealing strip. If excessive force is applied, and the sealing strip is securely attached, the connection between the bag body and the sealing strip can tear, hindering easy opening. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pull-string type plastic food sealing bag.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a drawstring plastic food resealable bag, including a bag body, a sealing component at the bag opening of the bag body, a concave fastener on the outer side of the bag opening of the bag body, a plurality of limiting blocks inside the groove of the concave fastener, the tips of the limiting blocks contacting the outer side of the bag opening, and a triangular or quadrangular pyramidal convex ridge at one end of the top wall of the groove of the concave fastener, the convex ridge extending into the bag opening.

[0005] Preferably, there are four limiting blocks, which are distributed at the front and rear ends of the two inner sidewalls of the concave fastener groove and are symmetrically arranged in pairs. Two adjacent limiting blocks are arranged opposite each other and a gap is left between them.

[0006] Preferably, the sealing assembly includes a first sealing assembly and a second sealing assembly, which are arranged sequentially from top to bottom on the inner sidewall of the bag opening.

[0007] Preferably, the first sealing assembly includes two first sealing strips symmetrically arranged on the inner sidewall of the bag opening. One of the first sealing strips has a plurality of first inserts arranged longitudinally, and the other first sealing strip has a first slot corresponding to the position, number and size of the first inserts. The first inserts can be inserted into the first slots.

[0008] Preferably, the second sealing assembly includes two second sealing strips symmetrically arranged on the inner sidewall of the bag opening. One of the second sealing strips has a second insert horizontally arranged on it, and the other second sealing strip has a second slot horizontally arranged corresponding to the position and size of the second insert. The second insert can be inserted into the second slot.

[0009] Preferably, two symmetrically arranged elastic sheets with a flat O-shaped cross-section are installed inside the concave groove of the fastener, and pressure rollers are rotatably installed on the outer side walls of the two elastic sheets via rotating seats.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This solution uses a concave fastener on the outside of the bag opening. By pressing the two ends of the concave fastener, the ends deform and press against the outside of the bag opening, thus closing the bag opening seal. By sliding the concave fastener, the seal inside the bag opening can be completely closed. When opening the bag, simply slide the concave fastener in the opposite direction, and the protrusions in the concave fastener will separate the closed seal. There is no need to pull the bag opening or body forcefully in the opposite direction, which facilitates the opening of the bag. Attached Figure Description

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0019] like Figures 1-3The illustrated resealable plastic food bag includes a bag body 1. A sealing component is provided at the bag opening of the bag body 1. A concave fastener 2 is provided on the outer side of the bag opening of the bag body 1. Multiple limiting blocks 6 are provided inside the groove of the concave fastener 2, with the tips of the limiting blocks 6 contacting the outer side of the bag opening. A triangular or quadrangular pyramidal convex ridge 7 is provided at one end of the top wall of the groove of the concave fastener 2, extending into the bag opening. When closing the bag opening, pressing the two ends of the concave fastener 2 causes them to deform and press against the outer side of the bag opening, thus closing the two sealing strips of the bag opening. Sliding the concave fastener 2 completely closes the sealing strips in the bag opening. When opening the bag opening, simply slide the concave fastener 2 in the opposite direction. As the convex ridge 7 moves, its inclined surface pushes the sealing strips on both sides, facilitating the separation of the closed sealing strips. There is no need to pull the bag opening or the bag body in the opposite direction, making the opening of the bag opening convenient.

[0020] There are four limiting blocks 6. The limiting blocks 6 are distributed at the front and rear ends of the two inner sidewalls of the concave fastener 2 groove and are symmetrically arranged in pairs. The two adjacent limiting blocks 6 are arranged opposite each other and a gap is left between them. The limiting blocks 6 are set on both sides of the bag opening. Due to the flexibility of the bag opening, when the tip of the limiting block 6 touches the surface of the bag opening, its surface deforms, so that the four limiting blocks 6 are connected to the outside of the bag opening due to friction.

[0021] The sealing assembly includes a first sealing assembly 4 and a second sealing assembly 5, which are arranged sequentially from top to bottom on the inner wall of the bag opening.

[0022] The first sealing assembly 4 includes two first sealing strips symmetrically arranged on the inner sidewall of the bag opening. One of the first sealing strips has a plurality of first inserts arranged longitudinally, and the other first sealing strip has a first slot corresponding to the position, number and size of the first inserts. The first inserts can be inserted into the first slots.

[0023] The second sealing assembly 5 includes two second sealing strips symmetrically arranged on the inner sidewall of the bag opening. One of the second sealing strips has a second insert horizontally arranged on it, and the other second sealing strip has a second slot horizontally arranged corresponding to the position and size of the second insert. The second insert can be inserted into the second slot.

[0024] The arrangement of the first sealing component 4 and the second sealing component 5 increases the stability of the food sealing bag connection. Example 2

[0025] Based on the above technical solutions, such as Figures 4-5 As shown, this solution also provides another embodiment, specifically: two symmetrically arranged elastic pieces 8 with a flat O-shaped cross-section are installed inside the groove of the concave fastener 2, and pressure rollers 9 are rotatably installed on the outer side walls of the two elastic pieces 8 through the rotating seat 3.

[0026] When the two ends of the concave fastener 2 are pressed, the deformation of the two ends of the concave fastener 2 causes the elastic pieces 8 to move synchronously. The two elastic ends of the two elastic pieces 8 push the pressure rollers 9 to press on the outside of the bag opening through the rotating seat 3. The cooperation of the two pressure rollers 9 can close the force-bearing points of the first sealing component 4 and the second sealing component 5. Then, the concave fastener 2 is pulled, and the concave fastener 2 drives the two pressure rollers 9 to roll synchronously on the outside of the bag opening. At this time, the reaction force generated by the elastic pieces 8 can be applied to the pressure rollers 9 and the concave fastener 2. The user only needs to keep pressing the concave fastener 2 constantly while sliding it, which reduces the deformation stroke of the two ends of the concave fastener 2. The operation is more labor-saving and can also avoid the situation where the sealing strip is too firmly connected due to excessive manual pressing of the sealing strip, thus protecting the plastic food sealing bag.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
