Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a self-sealing bag with high sealing performance. Background Technology

[0002] High-sealing self-sealing bags are an extremely convenient storage tool, especially suitable for storing various types of food. Due to their excellent sealing performance, these bags can largely maintain the freshness of food, preventing it from getting damp or contaminated, and are therefore widely used in daily household life. Almost every household uses these bags to store snacks, dried goods, condiments, and other food items. However, in actual use, people usually place the self-sealing bags containing food in cabinets or storage shelves. But existing high-sealing self-sealing bags have a significant drawback: as the food in the bag is gradually taken out and the volume decreases, the bag cannot adjust its height and shape to accommodate the remaining food. This results in the bag still occupying the same space as initially, failing to effectively save storage space and thus reducing the space utilization rate of cabinets or storage areas. Therefore, designing a high-sealing self-sealing bag is essential. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly airtight self-sealing bag.

[0004] The objective of this utility model can be achieved through the following technical solution: A high-sealing self-sealing bag includes a bag body with a bag opening at the top, a self-sealing strip one fixed to one side of the bag opening, a self-sealing strip two fixed to the other side of the bag opening, a raised edge on one side of the bag opening, a flexible strip fixed on the raised edge, and both ends of the flexible strip extending beyond the bag body, and elastic positioning heads connected to both ends of the flexible strip, and multiple auxiliary holes that cooperate with the elastic positioning heads at the sealing edges on both sides of the bag body, and the elastic positioning heads can be inserted into any one of the auxiliary holes.

[0005] The bendable strip includes a soft plastic strip and a metal wire. The soft plastic strip is fixed to the raised edge, and the metal wire is threaded through the soft plastic strip.

[0006] The bag body is formed by heat sealing two films on three sides or by heat sealing one film on both sides after folding it in half.

[0007] The bag body has transparent auxiliary sheets heat-sealed on three sides.

[0008] Compared with existing technologies, this high-sealing self-sealing bag has the following advantages: In this invention, after the self-sealing strip one and self-sealing strip two seal the bag opening, the length of the entire self-sealing bag can be changed by flipping the convex edge according to the amount of food stored in the self-sealing bag, thereby avoiding it taking up extra space in the cabinet. Attached Figure Description

[0009] Figure 1 This is a three-dimensional structural schematic diagram of the present invention; In the diagram, 1 is the bag body; 1a is the auxiliary hole; 1b is the raised edge; 2 is the auxiliary piece; 3 is the flexible strip; 3a is the elastic positioning head; and 4 is the self-sealing strip. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this high-sealing self-sealing bag includes a bag body 1 with a bag opening at the top. A self-sealing strip 4 is fixedly connected to one side of the bag opening, and a self-sealing strip 2 is fixedly connected to the other side of the bag opening. In this embodiment, the self-sealing strip 4 and the self-sealing strip 2 are existing products, which can seal the bag opening as needed. One side of the bag opening also has a raised edge 1b, on which a flexible strip 3 is fixed. The two ends of the flexible strip 3 extend beyond the bag body 1, and the two ends of the flexible strip 3 are connected to elastic positioning heads 3a. The sealing edges on both sides of the bag body 1 have multiple auxiliary holes 1a that cooperate with the elastic positioning heads 3a, and the elastic positioning heads 3a can be inserted into any one of the auxiliary holes 1a.

[0012] The bendable strip 3 includes a soft plastic strip and a metal wire. The soft plastic strip is fixed to the protruding edge 1b, and the metal wire is inserted inside the soft plastic strip. In this embodiment, the bendable strip 3 is an existing product.

[0013] The bag body 1 is made of two films heat-sealed on three sides or one film folded in half and then heat-sealed on both sides, which is achieved using existing technology.

[0014] The bag body 1 has a transparent auxiliary sheet 2 heat-sealed on three sides. With this structure, the upper part of the auxiliary sheet 2 forms an insertion opening, where a card with food information can be placed.

[0015] In this invention, after the self-sealing strip 4 and the self-sealing strip 2 seal the bag opening, the length of the entire self-sealing bag can be changed by flipping the convex edge 1b according to the amount of food stored in the self-sealing bag. After adjustment, the two ends of the flexible strip 3 are bent, and at the same time, the elastic positioning head 3a is inserted into the corresponding auxiliary hole 1a, thereby avoiding it from taking up extra space in the cabinet.

[0016] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
