Description

A rainproof document express bag

Technical Field

The utility model belongs to the technical field of express bags, and in particular relates to a rainproof document express bag.

Background Art

The express delivery industry is one of the fastest growing industries at present. It can help people transport and send various items. For some smaller items or paper documents, document express bags are generally used for packaging during express delivery.

In a Chinese patent with publication number CN211197131 U, an express document bag is disclosed. The express document bag has a reasonable design structure and is waterproof, fireproof and puncture-proof when in use, thereby preventing damage to stored documents. It also has a double-layer structure and double-layer protection. The inner waterproof bag inside can be recycled while providing good protection, thereby saving costs.

The express document bag in the above-mentioned comparative patent has a complex structure, resulting in high production costs. At the same time, when the sealing tongue is folded to allow the double-sided tape to adhere to the main bag body, there is still a certain gap between the sealing tongue and the main bag body, which makes it easy for rainwater to flow in through the gap, affecting the waterproof effect of the express document bag. Therefore, a waterproof express document bag with a simple structure is proposed, which can prevent rainwater from entering the inside of the bag body through the gap between the sealing tongue and the bag body.

Utility Model Content

The utility model aims to provide a rainproof document express bag to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions:

A rainproof document express bag, comprising:

Backing paper, wherein the left and right sides of the backing paper are connected to side edge strips, and the upper end of the backing paper is connected to a top edge strip;

The bottom of the facial paper is connected to the bottom of the backing paper and is provided with a document inlet and outlet;

A bag sealing tongue connected to the other end of the top edge sealing strip;

Degradable plastic waterproof paper is fixedly arranged on the back side of the backing paper, the side edge sealing strips, the top edge sealing strip and the sealing tongue.

Preferably, the side edge sealing strips and the top edge sealing strip are respectively adhered and fixed to the three sides of the back side of the face paper.

Preferably, a U-shaped double-sided adhesive tape is pasted on the front side of the bag sealing tongue, and a release paper is pasted on the surface of the U-shaped double-sided adhesive tape.

Preferably, a hand-tear head is connected to one side of the bag sealing tongue, and a tear strip corresponding to the position of the hand-tear head is fixed to the front side of the bag sealing tongue.

Preferably, the backing paper, the side edge sealing strips, the top edge sealing strip and the bag sealing tongue are all made of degradable cardboard.

Compared with the prior art, the beneficial effects of the utility model are:

(1) The utility model provides side sealing strips and top sealing strips on the backing paper to seal the backing paper and the face paper on four sides, so that documents can only enter the interior of the document express bag from the document inlet and outlet. By providing a bag sealing tongue and a U-shaped double-sided adhesive tape, the U-shaped double-sided adhesive tape and the face paper will cover the outside of the document inlet and outlet when pasted, making it difficult for moisture to enter the document inlet and outlet, thereby achieving a better waterproof effect. At the same time, the structure of this document express bag is simple and the manufacturing cost is lower.

(2) The utility model makes it difficult for moisture to penetrate into the document express bag by providing degradable plastic waterproof paper, and by providing the backing paper, side edge sealing strips, top edge sealing strips and bag sealing tongue all made of degradable cardboard, the document express bag is more environmentally friendly to use.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Example:

Please refer to Figures 1, 2 and 3, a rainproof document courier bag includes:

Backing paper 1, the left and right sides of the backing paper 1 are connected with side edge strips 11, and the upper end thereof is connected with a top edge strip 12;

The face paper 2 has a bottom connected to the bottom of the backing paper 1 and a document entrance and exit 21 formed thereon;

The bag sealing tongue 3 is connected to the other end of the top edge sealing strip 12;

The degradable plastic waterproof paper 7 is fixedly arranged on the back surface of the backing paper 1 , the side edge sealing strips 11 , the top edge sealing strip 12 and the sealing tongue 3 .

Specifically, as can be seen from FIG. 1 and FIG. 2 , the side edge sealing strips 11 and the top edge sealing strips 12 are respectively adhered and fixed to the three sides of the back side of the face paper 2 .

As can be seen from the above, since the side sealing strips 11 and the top sealing strips 12 are respectively adhered and fixed to the three sides of the back of the face paper 2, the back paper 1 and the face paper 2 are sealed on four sides by the side sealing strips 11 and the top sealing strips 12, so that the documents can only enter the interior of the document express bag from the document inlet and outlet 21. By providing a degradable plastic waterproof paper 7, moisture is prevented from penetrating from the surface of the document express bag. By providing a bag sealing tongue 3, it is used to block the document inlet and outlet 21 to prevent the documents from falling out while playing a waterproof role.

Specifically, as can be seen from FIG. 2 , a U-shaped double-sided adhesive tape 4 is pasted on the front side of the bag sealing tongue 3 , and a release paper is pasted on the surface of the U-shaped double-sided adhesive tape 4 .

As can be seen from the above, by setting the U-shaped double-sided tape 4, on the one hand, the sealing tongue 3 and the facial paper 2 can be adhered and fixed, and on the other hand, the three sides of the document inlet and outlet 21 can be blocked to prevent rainwater from flowing into the document inlet and outlet 21 from the position where there is no double-sided tape between the sealing tongue 3 and the facial paper 2.

Specifically, as can be seen from FIG. 1 and FIG. 2 , a hand-tear head 5 is connected to one side of the bag sealing tongue 3 , and a tear strip 6 corresponding to the position of the hand-tear head 5 is fixed to the front side of the bag sealing tongue 3 .

As can be seen from the above, by configuring the hand-tear head 5 and the tear strip 6 , after the document is delivered, when the hand-tear head 5 is pulled, the tear strip 6 can be driven to tear open the bag sealing tongue 3 .

Specifically, the backing paper 1, the side edge sealing strips 11, the top edge sealing strip 12 and the bag sealing tongue 3 are all made of degradable cardboard.

From the above, we can see that cardboard is a kind of paper with a certain hardness, which is not easy to become wrinkled. At the same time, it can be degraded in the natural environment, playing a green and environmentally friendly role.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
