Description

Technical Field

[0001] The utility model belongs to the technical field of industrial packaging, and specifically relates to a cubic bag for a new type of rubber lucky box. Background Art

[0002] A rubber lucky box is a specially designed container mainly used for transporting rubber products. This kind of box has specific dimensions and weights. Usually, the weight of a single box is 1.26 tons, and 16 boxes can be loaded into a container as a group. This design aims to improve transportation efficiency and reduce the breakage and transfer costs of goods during transportation.

[0003] The usage method of the lucky box is relatively simple and efficient. First of all, the lucky box can be folded, and its volume after folding is greatly reduced, which is convenient for storage and transportation. When in use, rubber products can be directly put into the lucky box. Since the design of the lucky box allows for fully enclosed transportation, there is no need to unload the goods during the transportation process from the source to the destination, reducing the risk of human-cargo contact. In addition, the lucky box can be directly handled and loaded and unloaded by a forklift, reducing the risk of goods breakage and the loading and unloading costs.

[0004] The advantages of the lucky box are mainly reflected in the following aspects: First, the fully enclosed transportation method effectively reduces the epidemic risk brought by human-cargo contact. Second, the design of the lucky box allows for direct handling by a forklift, simplifying the loading and unloading process and reducing the breakage and transfer costs of goods. Finally, the recyclable characteristic of the lucky box meets the environmental protection requirements and reduces resource waste.

[0005] Under normal circumstances, in order to better protect rubber products or other vulnerable items, users may place an inner bag in the rubber lucky box. These inner bags are used to store items separately to reduce the friction and collision between items. At the same time, the inner bag can also help users take out and store items more conveniently, improving work efficiency. In addition, the inner bag can prevent rubber products from being contaminated and play a role in isolation and dust prevention.

[0006] A Chinese patent with the application number CN201621372778.6 discloses a square-bottom bag, including a bag body. The upper end of the bag body is open. Its characteristics are that the bag body includes sides and a bottom surface. The sides are four vertical planes. The sides of the vertical planes are adhesively bonded to each other in sequence pairwise, and the bonding places form seam edges, and the seam edges protrude out of the bag body. The lower ends of the vertical planes are folded and heat-sealed to form the bottom surface, and the heat-sealing place forms a heat-sealing line. The square-bottom bag has good load-bearing, wear-resistant and moisture-proof effects;

[0007] However, the sides of this square-bottom bag adopt an adhesive processing technology, which is complex in operation, prone to breakage, and has a poor use effect. Content of the Utility Model

[0008] The main technical problem to be solved by the present utility model is to provide a new type of cubic bag for a rubber lucky box, which has a simple overall structure, can be applied in a rubber lucky box and can be closely laminated on the inner wall of the rubber lucky box, has a simple processing and forming process, improves production efficiency, is convenient for packaging and use, and can realize continuous and automated production, thereby improving the use effect.

[0009] To solve the above technical problems, the present utility model provides the following technical solutions:

[0010] A new type of cubic bag for a rubber lucky box includes a bottom bag body. On both opposite sides of the bottom bag body, there are symmetrically arranged first side bag bodies. On the other two opposite sides of the bottom bag body, there are symmetrically arranged second side bag bodies. At the connection of each first side bag body and the adjacent second side bag body, there is a second fold line. The bottom bag body, the first side bag bodies, and the second side bag bodies are made by heat-sealing and cutting an M-shaped film. The M-shaped film is made by blow-molding a base film.

[0011] The base film includes an inner film layer. On one side of the inner film layer, there is an adhered intermediate layer. On the side of the intermediate layer away from the inner film layer, there is an adhered outer film layer.

[0012] The overall thickness of the bottom bag body, the first side bag bodies, and the second side bag bodies is 0.05 - 0.06 mm.

[0013] The following are further optimizations of the above technical solutions by the present utility model:

[0014] The shapes of the bottom bag body, the first side bag bodies, and the second side bag bodies are all set as rectangles.

[0015] Further optimization: A horizontal heat-sealing line is provided at the middle position of the bottom bag body, and the width of the horizontal heat-sealing line is 0.4 - 0.6 cm.

[0016] Further optimization: A horizontal wide edge is provided on one side in the width direction of the horizontal heat-sealing line, and the width of the horizontal wide edge is set to 1.5 - 2.5 cm.

[0017] Further optimization: Symmetrically arranged wide edge groups are provided at both ends in the length direction of the horizontal wide edge.

[0018] Further optimization: The wide edge group includes two angled wide edges symmetrically arranged at one end in the length direction of the horizontal heat-sealing line, and the two angled wide edges respectively extend to two adjacent right-angle positions of the bottom bag body.

[0019] Further optimization: The width of the angled wide edge is set to 1.5 - 2.5 cm.

[0021] Further optimization: a first folding line is provided at the middle position of the first side pocket body.

[0022] The utility model adopts the above technical solutions, with ingenious conception and reasonable structure. It can be used in a rubber lucky box and can be closely laminated on the inner wall of the rubber lucky box to prevent the rubber from being contaminated, playing the roles of isolation and dust prevention. Moreover, during the production process of the cubic bag, by providing a wide-edge group, a horizontal wide edge, a folding corner heat-sealing line and a horizontal heat-sealing line on the bottom bag body, it is convenient to cooperate with a bag-making machine for cutting and bag-making, improving the production efficiency and quality of the cubic bag; the cubic bag is made by cutting and heat-sealing an M-shaped rolled film formed by blowing a base film on a co-extrusion blown film device. The base film adopts a three-layer structure of an inner film layer, a middle layer and an outer film layer, further enhancing the overall strength of the cubic bag and then improving the application quality.
