Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an envelope paper bag with a honeycomb lining. Background Art

[0002] An envelope paper bag is a paper packaging bag used to carry letters, documents and other items;

[0003] With the continuous development of technology, the unique design of honeycomb envelope bags enables them to effectively absorb and disperse shock when subjected to external force, providing all-round protection for the items inside. Whether mailing fragile items, books or other items that require special protection, honeycomb envelope bags can ensure that they are safe and intact during transportation;

[0004] It has been found in actual use that the existing envelope paper bags have the following deficiencies:

[0005] The existing envelope paper bags have relatively thin structures on both sides. When putting items into the envelope paper bag, people sometimes put their hands into the envelope paper bag to open the bag opening. When the palms approach the left and right sides of the paper bag opening and come into contact with the left and right sides of the paper bag opening, the paper bag opening expands outwards significantly, causing the two sides of the paper bag opening to tear.

[0006] Moreover, when encountering external and internal impacts, due to the structure of the paper bag, the force-bearing area on the left and right sides of the paper bag is much smaller than the force-bearing area on the front and back sides of the paper bag. The direct pressure transmitted to the two sides of the envelope paper bag by the objects in the bag is relatively large, making the envelope paper bag prone to bursting, resulting in high packaging loss of the envelope paper bag.

[0007] Therefore, the present application provides an envelope paper bag with a honeycomb lining to meet the needs. Utility Model Content

[0008] The purpose of the utility model is to solve the problems existing in the above background technology and to propose an envelope paper bag with a honeycomb lining.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] An envelope paper bag with a honeycomb lining comprises: a paper bag body, a paper sealing cover, a first rope buckle, a second rope buckle, a honeycomb lining, a reinforcement protection strip and a support strip. The paper sealing cover is provided at the upper end of one side of the paper bag body, the first rope buckle is installed on the surface of the paper sealing cover, and the second rope buckle is installed at the upper end of the back side of the paper bag body. The inside of the paper bag body is bonded with a honeycomb lining, the inside of the paper bag body is also bonded with a reinforcement protection strip, and the side of the reinforcement protection strip is bonded with a support strip.

[0011] Preferably, two groups of honeycomb liners are provided, and the two groups of honeycomb liners are mirror-symmetrically located at the front and rear ends of the interior of the paper bag body.

[0012] Preferably, the middle of the honeycomb liner is bent outward, and the left and right sides of the honeycomb liner are bonded to the inner edges of the paper bag body, and an open cavity exists between the bonded honeycomb liner and the paper bag body.

[0013] Preferably, two groups of reinforcing protection strips are provided, and the two groups of reinforcing protection strips are respectively located on the left and right sides of the interior of the paper bag body in a mirror-symmetrical manner, and the reinforcing protection strips separate the upper end opening of the paper bag body into a trapezoidal shape.

[0014] Preferably, the reinforcing protection strip and the supporting strip are both made of kraft paper, and the upper and lower ends of the reinforcing protection strip are bonded to the upper and lower edges of the inner side of the paper bag body.

[0015] Preferably, the reinforcing protection strip is trapezoidal in shape as a whole, and a trapezoidal closed cavity exists between the reinforcing protection strip and the paper bag body after being bonded.

[0016] Preferably, a plurality of groups of support strips are adhered to the side of the reinforcing protection strip, and the support strips are perpendicular to the reinforcing protection strip, and the other ends of the support strips are adhered to the side of the paper bag body.

[0017] Preferably, the reinforcing protection strip is rectangular, and the reinforcing protection strip divides the trapezoidal closed cavity formed between the reinforcing protection strip and the paper bag body into several groups of cavities.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. By sticking reinforcing strips on the left and right sides of the paper bag body, not only can the strength and tear resistance of the sides of the paper bag be enhanced, but also when objects are placed in the paper bag, they come into contact with the reinforcing strips, which can reduce the possibility of tearing on both sides of the paper bag opening when the hand is inserted into the paper bag to open it;

[0020] 2. After the reinforcement strip is bonded, there is a trapezoidal closed cavity between the reinforcement strip and the paper bag body, so that when the objects placed inside come into contact with the reinforcement strip outward, the reinforcement strip can be squeezed to provide cushioning. The reinforcement strip can be supported by the support strip, which not only improves the strength of the reinforcement strip, but also ensures the three-dimensionality and support of the reinforcement strip. When encountering external and internal impacts, the impact force can be more effectively dispersed evenly, thereby greatly reducing the direct pressure transmitted to the envelope paper bag, effectively preventing the envelope paper bag from bursting, improving the availability of the envelope paper bag, and reducing packaging loss.

DETAILED DESCRIPTION

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 An envelope paper bag with a honeycomb lining is shown in an embodiment of the present invention, comprising: a paper bag body 1, a paper sealing cover 2, a first rope buckle 3, a second rope buckle 4, a honeycomb lining 5, a reinforcing protection strip 6 and a support strip 7. The paper sealing cover 2 is provided at the upper end of one side of the paper bag body 1, the first rope buckle 3 is installed on the surface of the paper sealing cover 2, and the second rope buckle 4 is installed at the upper end of the back side of the paper bag body 1. The honeycomb lining 5 is bonded to the inside of the paper bag body 1, and the reinforcing protection strip 6 is also bonded to the inside of the paper bag body 1, and the side of the reinforcing protection strip 6 is bonded to the support strip 7.

[0031] In this embodiment, two groups of honeycomb liners 5 are provided, and the two groups of honeycomb liners 5 are mirror-symmetrically located at the front and rear ends of the interior of the paper bag body 1. The two groups of honeycomb liners 5 at the front and rear ends of the interior of the paper bag body 1 can clamp the placed objects in the middle, thereby cushioning and reducing shock for the objects inside the paper bag.

[0032] In this embodiment, the middle of the honeycomb lining 5 is bent outward, and the left and right sides of the honeycomb lining 5 are bonded to the inner edges of the paper bag body 1, and there is an open cavity between the honeycomb lining 5 and the paper bag body 1 after bonding. The cavity formed between the honeycomb lining 5 and the paper bag body 1 can act as a buffer structure, so that when the placed objects fall towards the honeycomb lining 5 during transportation, the honeycomb lining 5 can be squeezed to discharge the gas in the cavity formed by the separation, so that the shock absorption effect is better.

[0033] In this embodiment, two groups of reinforcing protection strips 6 are provided, and the two groups of reinforcing protection strips 6 are respectively located on the left and right sides of the interior of the paper bag body 1 in a mirror-symmetrical manner. The reinforcing protection strips 6 separate the upper end opening of the paper bag body 1 into a trapezoidal shape. By adhering the reinforcing protection strips 6 on the left and right sides of the interior of the paper bag body 1, not only can the strength and tear resistance of the side of the paper bag be enhanced, but also when objects are placed into the paper bag, they come into contact with the reinforcing protection strips 6, which can reduce the situation where the two sides of the paper bag opening are torn when a hand is inserted into the paper bag opening to open it.

[0034] In this embodiment, the reinforcing protection strip 6 and the supporting strip 7 are both made of kraft paper, and the upper and lower ends of the reinforcing protection strip 6 are bonded to the upper and lower edges of the inner end of the paper bag body 1. The reinforcing protection strip 6 and the supporting strip 7 made of kraft paper are relatively tough and have strong tear resistance.

[0035] In this embodiment, the reinforcing protection strip 6 is trapezoidal in shape as a whole, and after being bonded, a trapezoidal closed cavity exists between the reinforcing protection strip 6 and the paper bag body 1, so that when objects placed inside contact the reinforcing protection strip 6 outward, they squeeze the reinforcing protection strip 6 and provide buffering.

[0036] In this embodiment, a plurality of groups of support strips 7 are adhered to the side of the reinforcing protection strip 6, and the support strips 7 are perpendicular to the reinforcing protection strip 6, and the other end of the support strip 7 is adhered to the side of the paper bag body 1. The reinforcing protection strip 6 can be supported by the support strips 7, which not only improves the strength of the reinforcing protection strip 6, but also ensures the three-dimensionality and support of the reinforcing protection strip 6. When encountering external and local impacts, the impact force can be more effectively dispersed evenly, thereby greatly reducing the direct pressure transmitted to the envelope paper bag, effectively preventing the envelope paper bag from bursting, and improving the availability of the envelope paper bag and reducing packaging losses.

[0037] In this embodiment, the reinforcing protection strip 6 is rectangular, and the reinforcing protection strip 6 divides the trapezoidal closed cavity formed between the reinforcing protection strip 6 and the paper bag body 1 into several groups of cavities, so that when the reinforcing protection strip 6 or the supporting strip 7 at a certain position is bent and broken, the overall support can still be guaranteed.
