Abstract

An envelope has a flap (3) of which the inside surface has a layer of pressure-sensitive adhesive which is protected by a wider strip of release paper (4) before use. Preferably, a tear strip (6, 7) made of tough material is stuck to the adhesive just above the folding line between the flap (3) and the front of the envelope. The pressure-sensitive adhesive may comprise double-sided adhesive tape. <IMAGE>

Description

AN ENVELOPE The present invention relates to an envelope which may be sealed without using additional glue or paste and may be opened without using any cutting tools so that the contents of the envelope will be kept undamaged.
Nowadays, there are various newly developed communicating means, such as telephone, telex, telegra and facsimile. However, documents fast transmitted by those means would not always be considered and used for a formal contract, of which the confidentiality must be protected. Besides, the cost of those means is very expensive. Therefore, sending documents or small articles by enclbsing them in an envelope is still one of the most effective, most convenient ways of transmission of information.
However, when sealing a conventional envelope, paste or glue is usually needed but not always available, it is not easily controlled over the volume used and consequently often smears the user's hand or surrounding enviroment.
There is a kind of envelope having a layer of adhesive which has to be wetted. Since water is not always available in some places, some people seal such envelopes with their own saliva. This is not hygienic.
Another shortcoming of a conventional envelope is that the contents contained therein are frequently damaged when the envelope is carelessly opened by hand or cutter and consequently, causing uncountable losses. Even when a letter opener or a pair of scissors is aailable, it takes time to locate it and has the risk of damaging the contents thereof as a result of carelessness.
The present invention provides an envelope in which: the flap has a layer of pressure-sensitive adhesive along the inside surface which is protected by a strip of release paper; the release paper having a width slightly greater than that of the pressure-sensitive adhesive.
Preferably, the pressure-sensitive adhesive is provided by double-sided adhesive tape of which the liner has a width greater than that of the adhesive pad.
Preferably, the flap has a tear strip for opening the envelope.
In the accompanying drawings; Figure 1 is a perspective view of an envelope; Figure 2 is an enlarged, fragmentary perspective view of the circled area of Figure 1 showing the protective release paper (or liner) being peeled off; Figure 3 is a perspective view of the envelope showing the tear strip and its tab being torn away; and Figure 4 is a perspective view of the envelope showing a pre-formed indentation at the end of the tear strip.
The envelope has a front 1, a back 2, and a folding flap 3. On and along the inside surface of the flap 3, there is a layer of pressure-sensitive adhesive which is protected by a release paper 4 which has a width slightly greater than that of the adhesive so that it may be peeled off easily. Just above and adjacent to the folding line 5 between the flap 3 and the front 1, a tear strip 6 made of tough material is stuck on the pressure-sensitive adhesive. The tear strip 6 may either have a tab 7 extending from a side edge of the flap 3 or have a preformed indentation at each of its ends so as to facilitate the tearing of the tear strip 6.
When using the envelope, the release paper 4 on the cover 3 is simply peeled off, the flap is folded downward toward the back 2 and a light pressure will seal the envelope accordingly. When opening the envelope, the tab 7 is simply lifted away and the flap 3 will be split smoothly along the tear strip 6 without damaging the front 1 or the back 2, since the tear strip will not stick to them, and the contents in the envelope will not be damaged carelessly.
The pressure sensitive adhesive may be provided by a double-sided adhesive tape of which the liner has a width slightly greater than that of the adhesive pad.
