Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to an anti-fouling packaging bag. Background Art

[0002] Packaging bags refer to bags used to package various items, making it convenient to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production.

[0003] When using existing bagged flour, a measuring spoon can be used instead of pouring it out to take a certain amount of flour.

[0004] However, due to the friction and tension between the flour, the amount of flour scooped up with a measuring spoon is usually more than the volume of the measuring spoon. When people only want to scoop up a spoonful of flour, they need to use their fingers or other methods to scrape off the flour that exceeds the measuring spoon, which is unhygienic.

[0005] In view of the above problems, an anti-fouling packaging bag is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments.

[0023] An antifouling packaging bag, such as Figure 1 、 Figure 2 as well as Figure 3 When the bag is packed up, the bag 1 is put into the bag 1 and the bag is put into the hopper 3. When the bag is packed up, the bag 1 is put into the hopper 3 and the bag is put into the hopper 3. When the bag is packed up, the bag 1 is put into the hopper 3. When the bag is packed up, the bag 1 is put into the hopper 3. When the bag is packed up, the bag 1 is put into the hopper 3.

[0024] Instructions for use: Taking the bag 1 containing flour as an example, when using the packaging bag, the user presses the connection position of the scraper plate 4 and the limit assembly 5 on the outside of the packaging bag to disassemble and separate the scraper plate 4 and the limit assembly 5, so that the torsion spring 6 releases its elastic potential energy, thereby driving the scraper plate 4 to rotate around its rotating axis at one end away from the base 3 until the scraper plate 4 opens the bag 1. At this time, the flour in the packaging bag can be easily taken out. When it is necessary to scoop flour precisely, the end face of the spoon can be scraped along the edge of the scraper plate 4 to make the flour higher than the end face of the spoon fall back into the packaging bag.

[0025] Practical effect: By pressing the position where the scraper plate 4 and the limit component 5 are engaged, the scraper plate 4 and the limit component 5 are separated, so that the torsion spring 6 releases elastic potential energy to drive the end of the scraper plate 4 away from the base 3 to rotate around its rotating axis to the inner wall of the bag body 1 away from the limit component 5. When precise material removal is required, the scraper plate 4 can be used for scraping without direct contact with the flour by hand, thereby improving the hygiene and convenience of the packaging bag.

[0026] like Figure 4 、 Figure 5 as well as Figure 6 As shown, specifically, the limiting assembly 5 includes a clamping seat 51, a buckle 52 and a spring 54. The clamping seat 51 is provided with a receiving groove 511. The clamping seat 51 is fixedly bonded to the bag body 1. The buckle 52 is slidably arranged in the receiving groove 511. The end surface of the buckle 52 passing through the receiving groove 511 is formed with two clamping blocks 521 that can elastically deform and clamp the chimeric block 41 when sliding into the receiving groove 511. One end of the spring 54 is fixed to the bottom of the receiving groove 511, and the other end of the spring 54 is connected to the buckle 52. A limiting member is provided between the clamping seat 51 and the buckle 52. By pressing the buckle 52 toward the receiving groove 511, the two clamping blocks 521 slide out of the receiving groove 511 through the thrust of the spring 54.

[0027] The limiting member includes a pull rod 53 rotatably connected to the buckle 52. A protrusion 531 is formed on the end surface of the pull rod 53 away from the buckle 52. A sliding groove 512 is formed on the inner wall of the receiving groove 511 to accommodate the sliding of the protrusion 531. When the pull rod 53 is pressed, the protrusion 531 can slide unidirectionally along the sliding groove 512 to two positions with different depths along the receiving groove 511. The position of the protrusion 531 is fixed by the elastic force of the spring 54.

[0028] Among them, when the scraper plate 4 rotates and presses the limit component 5 for the first time, the spring 54 contracts, and the buckle 52 slides into the accommodating groove 511, so that the clamping block 521 bites into the interlocking block 41 to fix the scraper plate 4. When the scraper plate 4 presses the limit component 5 for the second time, the spring 54 returns to its position, so that the buckle 52 slides out of the accommodating groove 511, so that the clamping block 521 is disengaged from the interlocking block 41.

[0029] like Figure 2 as well as Figure 3 As shown, an elastic pad 7 is fixedly provided on the side of the bag body 1 away from the scraper plate 4, and the side of the scraper plate 4 away from the interlocking block 41 can be in contact with the elastic pad 7. The setting of the elastic pad 7 allows the scraper plate 4 to relieve the elastic potential energy generated by the rotation of the torsion spring 6 when it rotates away from the bag body 1, while protecting the bag body 1, further improving the practicality of the packaging bag.

[0030] In this specific embodiment, the scraper plate 4, the base 3, the connecting seat 51, the buckle 52 and the pull rod 53 are all made of food-grade PP plastic, and the bag body 1 is a durable composite bag.

[0031] like Figure 2 、 Figure 3 As shown, further, a slot 42 for fixing a spoon is provided on the end surface of the scraper plate 4 away from the engaging block 41, so that the spoon can be carried together with the packaging bag, thereby improving the practicality of the packaging bag.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
