Description

TECHNICAL FIELD

[0001] The utility model relates to a sealed bag which prevents children from opening. BACKGROUND

[0002] The sealed bag (also known as a dense bag, a bone bag, a zipper bag, a keel bag) is made of polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) through blown film forming, a heat cutting machine, and is a plastic bag that can be repeatedly sealed. Common materials include PE, POE, and EVA. The sealed bag has many advantages and has become an indispensable daily necessity in daily life, widely used in product packaging, storage of food, jewelry, medicine, cosmetics, frozen food, and postal products.

[0003] The sealing structure of the sealed bag is usually a sealing strip installed at the bag opening to form a snap-fit seal. When opening, the two sides of the bag opening are pulled outward, and the sealing strip at the bag opening is opened from the pulling position, thereby opening the entire sealing strip at the bag opening. This is the most common and simplest way to open a sealed bag, and it is also the most widely used opening method. Since this opening method is the most common and ordinary, adults, unmarried people, or children can easily open the sealed bag by simple operation. However, if the sealed bag contains items that children should not touch (such as small and sharp jewelry, blades, or non-edible powders, granules, medicines, etc.), it poses a great risk to children, such as cuts or accidental ingestion. Therefore, designing a sealed bag that prevents children from opening is the research direction of the utility model. SUMMARY

[0004] The utility model provides a sealed bag which prevents children from opening, which can effectively solve the above problems.

[0005] The utility model is implemented as follows:

[0006] A sealed bag which prevents children from opening, comprising

[0007] a bag body;

[0008] a sealing end arranged at the opening of the bag body, and a connecting hole symmetrically formed on the sealing end;

[0009] a locking structure arranged on the sealing end and cooperating with the connecting hole; the locking structure comprises a first locking plate and a second locking plate, a first locking groove and a second locking groove formed on the first locking plate and the second locking plate, and a buckle member arranged at the side edge of the first locking plate and the second locking plate;

[0010] A connecting rod is arranged through the first lock plate, the second lock plate and the connecting hole, so that after the first lock plate and the second lock plate are buckled, the connecting rod is buckled by the buckle, and then the first lock plate and the second lock plate are fixed.

[0011] The utility model discloses the beneficial effect is:

[0012] (1) the utility model discloses a sealing end is arranged at the opening of bag body, and the connecting hole is formed on the sealing end symmetrically, and the use of lock structure is cooperated, the efficient sealing and fixed of bag body are realized.

[0013] The lock structure is composed of a first lock plate and a second lock plate, which are connected to each other through a lock slot and a buckle, and are penetrated by a connecting rod through the lock plate and the connecting hole, so that the two lock plates can be fixed by the buckle after buckling. This design not only improves the sealing performance of the bag body and prevents the contents from leaking, but also enhances the stability and reliability of the lock structure through the cooperation of the buckle and the connecting rod.

[0014] In addition, the design of the connecting rod allows the first lock plate and the second lock plate to be easily disassembled when needed, facilitating maintenance and replacement. In summary, the case can ensure the sealing and safety of the bag body under various use conditions, while maintaining the convenience of operation, and has significant practical value and market potential.

[0036] The surfaces of the first locking plate 300 and the second locking plate 306 are each provided with a two-dimensional code (not shown in the figure) for understanding opening of the bag body 10.

[0037] Working principle:

[0038] First, the sealing end is equipped with symmetrical connecting holes 200, which are closed by a locking structure 30 composed of two locking plates. The two locking plates (300, 306) are matched with each other through the locking grooves (303, 3064) and the side buckles, and the buckles are connected with the buckling covers (305, 3063) with internal rubber rings. The buckling covers (305, 3063) are tightly fixed with the connecting rods 40 penetrating through the locking plates (300, 306) and the connecting holes 200, so as to prevent unauthorized opening, especially for children. One end of the locking plate (300, 306) is designed with a clamping part 301 and a butt joint part 3060, and the two are connected through the clamping of the clamping teeth 302 and the clamping groove 3061. The round hole 3030 in the locking groove (303, 3064) is accurately matched with the connecting rod 40, and the inclined inclined section 3031 ensures that the connecting rod 40 is stable and not easy to fall off. In addition, the extrusion part 307 at the lower end of the locking plate (300, 306) is embedded with a magnet, which is attracted to the corresponding magnet on the other locking plate, further enhancing the sealing effect. Finally, the surface of the locking plate (300, 306) is printed with a two-dimensional code, which provides a convenient way to track the opening state of the bag body. The whole system realizes the effect of being safe and user-friendly through the dual action of mechanical force and magnetic force.

[0039] The preferred embodiments of the utility model have been described above, and are not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
