Description

Environment-friendly paper bag for salt filling

Technical Field

The utility model relates to the technical field of water purification treatment, in particular to an environment-friendly paper bag for packaging soft water salt.

Background

In the water purification treatment link, soft water salt is needed to be utilized for softening water quality. When in packaging, soft water salt is packaged in a special plastic packaging bag in a granular or block form, then the packaging bag is sealed, and when in use, the bag body needs to be disassembled so as to take out the soft water salt. Because soft water salt has certain hardness, and the weight of soft water salt loaded in a bag body is heavier, the existing plastic packaging bags are mutually extruded and rubbed in the repeated carrying and stacking processes, and the problem of bag body breakage is unavoidable.

There are several types of plastic packages in the prior art, such as chinese patent publication CN 201427742Y. Considering the problems of easy breakage and insufficient environmental protection of plastic bags, the Chinese patent with the authorized bulletin number of CN208775345U discloses a paper bag, which solves the environmental protection problem, but is used in the salt filling process, because the structural strength of the paper bag is insufficient, the bag bodies are repeatedly knocked in the transportation and stacking processes, and the phenomena of bag body breakage and leakage can be inevitably caused.

Detailed Description

The utility model will be further described with reference to figures 1-6 and the specific examples. For convenience of description, the length direction of the bag body 1 is set to be the up-down direction, and both sides of the bag body 1 are left and right sides.

As shown in fig. 1 and 2, an environment-friendly paper bag for salt filling comprises a bag body 1, wherein a paper tube penetrating up and down is flattened to form the bag body 1, and the upper port and the lower port of the bag body 1 are of a sealing structure, namely, the upper port and the lower port of the bag body 1 are sealed, which is the method in the prior art.

In order to overcome the drawback of prior art, this patent improves the seal structure of the upper port, the lower port of the bag body 1, has also improved bag body 1 self.

The sealing structures of the upper port and the lower port of the bag body 1 are paper seals 2, and the paper selected by the seals 2 has certain strength and is durable according to the use requirement.

As shown in fig. 3, the seal 2 has an adhesive surface (like an adhesive tape), the seal 2 is folded in half and the adhesive surface is fixed and attached to each other, and the upper/lower port of the bag 1 is sandwiched, and the seal 2 adheres to the bag 1 and completely covers and seals the upper/lower port of the bag 1.

The seal 2 extends along the width direction of the bag body 1, the width of the seal 2 is larger than that of the bag body 1, and two ends of the seal 2 respectively protrude out of two side edges of the bag body 1.

In the manufacturing process, the upper and lower ports of the bag body 1 are flattened, so that the upper and lower port areas of the inner wall of the bag body 1 are relatively attached and bonded, and the preliminary sealing operation is completed; then, the seal 2 is utilized to fold and clamp the upper port/lower port of the bag body 1, and then the two seals 2 are bonded, so that the two seals 2 bond the bag body 1 and cover the upper port and the lower port of the bag body 1 respectively, the upper port and the lower port of the bag body 1 are sealed by the folded seal 2, and the seal 2 is folded and the bonding surfaces of the two seals are relatively attached, so that the sealing structure of the upper port and the lower port of the bag body 1 is reinforced, and the bag body is not easy to break in the transportation and stacking processes.

Because the width of the seal 2 is greater than the width of the bag body 1, and the two ends of the seal 2 respectively protrude out of the two sides of the bag body 1, the two ends of the seal 2 form handles which are convenient for a carrier to hold, and the two ends of the seal 2 can be held by the carrier, so that the environment-friendly paper bag containing softened salt can be carried very conveniently.

In order to strengthen the overall structural strength of the bag body 1, the load demand and the transportation demand are met, breakage is prevented, and the two side edges of the bag body 1 are reinforced.

In order to reinforce the two sides of the bag 1, as shown in fig. 1 and 4, in the first embodiment, the two sides of the bag 1 are folded into M-shape (i.e. the cross section is M-shape) from the view of the cross section, and a V-shaped portion 11 is formed in the middle and recessed toward the inner cavity of the bag 1, and the two portions of the V-shaped portion 11 are adhered and fixed to the inner wall of the bag 1. That is, during the manufacturing process, both side edges of the bag body 1 are folded into an M shape and then bonded together so that the side edges become thickened portions, thereby forming a reinforcing edge structure.

In order to reinforce the two sides of the bag 1, as shown in fig. 2 and 5, in a second embodiment, the two sides of the bag 1 are integrally connected with side protruding strips 12, and the side protruding strips 12 extend along the whole length of the bag 1, so as to enhance the structural strength of the two sides of the bag 1.

In order to reinforce the bag body 1 itself, as shown in fig. 6, in a third embodiment, the bag body 1 has a double-layer structure, wherein an inner layer is an inner PE layer 13, and an outer layer is a paper outer paper layer 14, and in the manufacturing process, the bag-shaped outer paper layer 14 is sleeved on the outer surface of the bag-shaped inner PE layer 13, and then the inner PE layer 13 is adhered to the inner wall of the outer paper layer 14.

Because the outer paper layer 14 is made of kraft paper, the seal 2 is also made of kraft paper, the inner PE layer 13 is arranged into a woven structure (woven bag), and a firm bag body 1 is formed after the outer paper layer 14 and the inner PE layer 13 are combined, so that the requirements of transportation are met, the bag has stronger bearing capacity, and can bear the collision of external objects and the collision of salt blocks or salt particles in the bag body 1.

The foregoing is a preferred embodiment of the present utility model, and various changes and modifications may be made therein by those skilled in the art without departing from the general inventive concept, and such changes and modifications should be considered as falling within the scope of the present utility model as defined in the appended claims.
