Detailed ways

Below in conjunction with specific embodiment and description accompanying drawing, the present invention will be further elaborated and described:

Please refer to FIGS. 1 to 2 , the present invention discloses a new type of environmentally friendly paper bag body, which is used for express delivery, postal service, and packaging. Specifically, the bag body is composed of a plane structure 10, and the plane structure 10 includes a paper first surface 11 and an inner core layer 12 attached to the first surface 11 for buffering and protection. The inner core layer 12 includes at least one layer of a liner 120, and the liner 120 is a paper material having a plurality of unevenly arranged shapes after being molded.

In this embodiment, the inner core layer 12 increases the thickness of the liner 120 through the shape of the uneven arrangement, and has a certain elasticity within the thickness range, and the protruding part bears the pressure to play a buffering role, so as to protect the articles. the goal of. The liner 120 is also a paper material, which can be recycled without causing pollution to the environment; meanwhile, the liner 120 is produced by molding, with mature molding technology and low cost, which is favorable for mass production.

Referring to FIG. 3 , the planar structure 10 further includes a second surface 13 , and the inner core layer 12 is sandwiched between the first surface 11 and the second surface 13 . As shown in FIG. 4 , FIG. 4 is a new type of environmentally friendly paper bag body formed by folding the plane structure 10 of FIG. 3 . At this time, the new type of environmentally friendly paper bag body intersects and adds a second surface 13 in FIG. 2 .

In this embodiment, by adding the second surface 13, the inner core layer 12 can be better fixed, and at the same time, the force strength of the new environmentally friendly paper bag body is improved, and the protection effect is further enhanced.

Wherein, the flat structure 10 is folded and sealed, or two flat structures 10 are stacked and sealed to form the bag body.

That is to say, there are at least two ways to make the bag body. The first way is to fold the plane structure 10 along a center line, and then glue and seal the edges on both sides perpendicular to the folding line to form the bag body; Two sheets of planar structures 10 are stacked, and then three sides of the edges of the planar structures 10 are sealed to form a bag body. In addition, the formation of the bag body may also include other embodiments, as long as it is formed by the planar structure 10 described in the present invention, it is all within the protection scope of the present application.

Referring to FIG. 1 and FIG. 5 , the gasket 120 includes a convex portion 121, and the convex portion 121 includes a plurality of protruding ribs 122. Relative to the ribs 122, a concave portion 123 is formed outside the edge of the ribs 122, so The convex portion 121 and the concave portion 123 are interposed.

In this embodiment, the ribs 122 formed after molding and the concave parts 123 formed on the edges of the ribs 122 are interposed, so that the plurality of ribs 122 can bear the pressure at the same time. For the bag body, the acceptance is uniform, and the plurality of ribs 122 buffer simultaneously. deformation, which can further improve the buffer capacity.

Referring to FIGS. 5 and 6 , the ribs 122 are provided with chamfers 1220 toward the concave portion 123 outside the edge, so that the convex portion 121 smoothly transitions to the concave portion 123 .

In this embodiment, on the one hand, the rounded chamfer 1220 can make the connection between the convex part 121 and the concave part 123 smoother, so that when the convex part 121 is deformed by force, it can obtain better support and improve the buffer effect; on the other hand, in the When the ribs 122 are formed after molding, the convex portion 121 and the concave portion 123 can be prevented from changing too steeply, causing damage to the paper when the mold is pressed, and improving the yield of the gasket 120 .

In the present invention, the arrangement of the ribs 122 has various ways, and only a relatively simple and representative way is described here. It should be considered that the number of the ribs 122 and the position of the ribs 122 should be as long as they can meet the above-mentioned content. content protected by this patent.

Specifically, referring to FIG. 1 , the rib 122 includes at least a first rib 1221 and a second rib 1222 . Here, there is at least one of the first rib 1221 and the second rib 1222 , and of course there may be multiple or multiple ribs. The arrangement of 122 is tiled on the entire paper, wherein the first rib 1221 and the second rib 1222 intersect with each other, and the concave portion is formed relative to the outer edges of the first rib 1221 and the second rib 1222 123. The first rib 1221 and the second rib 1222 are perpendicular to each other, the first rib 1221 and the second rib 1222 enclose a quadrangular area, and the quadrangular area is the recess 123 .

In another embodiment of the present invention, referring to FIG. 7 , the rib 122 further includes a third rib 1223 , the first rib 1221 , the second rib 1222 and the third rib 1223 intersect and enclose each other, thereby A triangular area is formed, and the triangular area is the recess 123 .

In other embodiments of the present invention, as shown in FIG. 8 , the rib further includes a fourth rib 1224 , a plurality of the first rib 1221 , the second rib 1222 and the fourth rib 1224 are respectively arranged in parallel, and the two The first rib 1221 , the second rib 1222 and the fourth rib 1224 intersect and enclose each other, thereby forming an octagonal area, and the octagonal area is the concave portion. The number of ribs 122 can also be more, such as 8, and the plurality of ribs 122 form an octagon. After being molded by the plurality of ribs 122, a specific convex portion 121 is formed, which can also achieve the function of buffer protection.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that , the technical solutions of the present invention may be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
