Description

Reusable Postal Express Mail Envelopes

technical field

The utility model belongs to the technical field of modern office supplies, and relates to a method for improving the structure of a postal express mail envelope, more specifically, an environmentally friendly and reusable postal express mail envelope.

Background technique

With the continuous development of society and the continuous progress of science and technology, people pay more and more attention to energy conservation and environmental protection. In today's society, while the rapid development of productivity has brought huge benefits to people, it has also caused extremely serious damage and waste to the environment and energy. People have gradually realized the irreparable damage caused by the excessive development and use of energy to the earth on which they depend for survival. Therefore, environmental protection experts appeal: Slow down, learn from the pain, save energy, and protect the environment are the real problems that people in today's society need to solve urgently.

In people's daily work, most of mailing documents rely on postal express delivery to complete. Therefore, the usage of postal express mail envelopes at home and abroad is very huge. The main raw material of the current postal express envelopes is wood pulp, which is made of cardboard into envelopes of various shapes. The basic shape of the general envelope is: The body (including the front and back sides) is an envelope cover that is integrated. Generally, the left and right sides of the envelope are pre-sealed first, and then there is an unsealing area with a self-adhesive strip on the pasting part of the envelope cover. The left and right ends of the envelope cover There is an extended unsealing handle, and a small discontinuous truncation line is die-cut along the unsealing area inward of the handle. When the document is placed in the envelope, the release paper covered on the hot-melt adhesive strip on the envelope cover is uncovered, and the The envelope flap is folded down and glued closed. When the addressee receives the express envelope, he can tear the envelope handle inwardly along the truncation line to remove the easy-tear strip, open the envelope, and take out the document.

In addition to the shortcoming of the postal express mail envelope that people use daily, it can only be used once, causing waste. The easy-tear strip at the unsealing place is not easy to be completely torn, and the easy-tear strip is often torn off after being torn for a while. Therefore, after people generally use it once, the express envelope becomes a waste product and is thrown into the trash can, which invisibly causes an extreme waste of resources.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a reusable postal express mail envelope, which is a further improvement to the original express mail envelope.

The technical scheme of the utility model is as follows:

A reusable postal express mail envelope is composed of an envelope body (5) and an envelope cover (4) integrated with the envelope body, and is characterized in that two or two lines are sprayed on the envelope cover (4). Hot-melt tape covering the release paper above; paste the easy-tear strip with the unsealing line on the lower part of the tape. Wherein said unsealing line adopts die-cutting continuous truncation line auxiliary easy-tear strip to open envelope.

The preferred express delivery envelope of the utility model, wherein said envelope cover is sprayed with hot-melt adhesive tapes (1A), (1B) with substantially the same length as the envelope cover (4) and an easy-to-tear adhesive tape with a die-cut continuous cut-off unsealing line. Articles (2A), (2B).

The utility model can also be designed as another reusable postal express delivery envelope according to the needs of customers, which comprises an envelope body (5) and an envelope cover (4) connected with the envelope body as a whole, and is characterized in that: (4) Spray one or more hot-melt adhesive tapes covered with release paper on the top, and paste an easy-to-tear strip with a die-cut continuous truncation of the unsealing line at a lower position relative to the tape; spray and paste on the envelope body (5) One or more strips of hot melt tape covered with a release liner.

The preferred express delivery envelope of the utility model is to spray and paste one or more hot-melt adhesive tapes (1B) on the envelope body (5), wherein the position of (1B) is the back side of the envelope body (5) covered by the upper cover folded down The relative position of the easy-tear strip (2B) remains unchanged. That is to say, the easy-tear strip (2B) with a die-cut continuous truncated unsealing line is positioned on the envelope cover (4). {The position of the new tape is limited by the original position (1B). After the top cover is folded down, the position of the back of the envelope covered by position (1B) is the position of the new tape}.

The envelope body (5) described in the utility model can be made of cardboard, and can also be other various wear-resistant envelopes. With the continuous development and progress of society, composite envelopes with fibers can further increase the wear resistance of the envelope body. At this time, the preparation method of the present invention can be used to add 3-4 hot-melt strips on the envelope cover (4). Adhesive tape can be used repeatedly, reduce costs and save resources. You can also paste 2-3 pieces of hot-melt tape covering the release paper on the envelope body, which can increase the number of times the EMS envelope is used.

There is no special requirement for the distance of spraying two or more hot-melt adhesive tapes covering the release paper on the envelope cover (4) described in the utility model. Generally, the shape of the envelope and the envelope cover (4) The size of the hot melt tape is determined, the distance between the two hot melt tapes is generally 1cm-5cm, preferably 1cm-4cm, more preferably 1.5cm-3cm, and the length of the hot melt tape is basically the same as the length of the corresponding envelope cover.

The easy-to-tear strip with die-cutting and continuous truncation of the unsealing line attached to the lower position of the adhesive tape described in the utility model mainly refers to that the distance of the hot-melt adhesive tape is generally 0.2cm-2cm, preferably 0.2cm-1.5cm , more preferably 0.4cm-1cm, paste the easy-tear strip with a die-cut continuous cut-off unsealing line; the length of the easy-tear strip is basically the same as the length of the corresponding envelope cover; the easy-tear strip is generally made of paper with better texture or Made of plastic sheet.

The shape of the unsealing line on both sides of the envelope cover (4) has no special requirements. Generally, it can be designed as a crescent or a horizontally placed V-shaped or semicircular shape for the convenience of opening. This is mainly for the convenience of opening. After reading the technical solution of the present invention and being inspired, the size, shape, material, etc. can be adjusted appropriately, but still belong to the protection scope of the present invention.

Compared with the express mail envelope generally used in the market, the reusable postal express mail envelope of the present invention has positive effects:

(1) The inventor comprehensively considered factors such as its technology, function, and material, and redesigned the use function of the express envelope, and sprayed and pasted two or more lengths on the envelope cover (4) and the length of the envelope cover is basically the same Hot melt adhesive and easy-tear strip and die-cut continuous unsealing lines on both sides of the easy-tear strip. The number of times of use is changed from once to twice or even more, and from non-recyclable to recyclable envelopes, which greatly saves resources, reduces costs, and is simple to make, which is more suitable for large-scale industrial production.

(2) The present invention improves the unsealing method of the existing postal express mail envelope. By adding a die-cut continuous cut-off line, the opening of the envelope is more convenient, and the phenomenon that the easy-to-tear strip is torn to a section and cannot be torn to the end is prevented. Occurrence, thereby more effectively guaranteeing the reuse of postal express mail envelopes.

(3) The reusable postal express mail envelope of the present invention is easy to use. When taking documents, you only need to gently pull up the easy-to-tear strip, and you can easily tear the easy-to-tear strip from one end to the other end, ensuring the fracture Neat and uniform, no damage to envelopes, can make envelopes to be used again.
