Description

Easy-to-tear envelope having glue sealing strip

The utility model relates to a kind of improvement to the common standard envelope.

There are some shortcomings like this in the shandardized envelope that uses in the daily life: will use paste when needs seal, tend to delay mailing so at hand when having the unsealed letter of an envelope to send and not having paste; If it is uneven directly to tear often poor tooth with hand when unpacking, the preservation that is unfavorable for mail again neither attractive in appearance is when the mail overfill also may be torn mail at that time.

The purpose of this utility model be design a kind of need not add that glue and paste just can ties and, and be convenient to break seal neat appearance and the envelope being convenient in the future preserve again after the unpacking.

The purpose of this utility model is achieved in that when producing and is coated with the last layer non-drying glue and carries out lid with protective film on envelope envelope tongue.Fine rule at the pre-buried band glue in the folding trace position of envelope tongue.When sealing protective film is torn the folding back of envelope tongue firmly by getting final product on envelope.During unpacking a end of a thread is stripped out, another the end of a thread is pinned prevented extraction, the envelope tongue can be severed from folding the trace position with the shearing force that pulls moving fine rule generation.

The utility model is because be basic design with the shandardized envelope, so be suitable for the shandardized envelope of various models, it can not influence the automatic go-on-go of mail, does not need the unpacking of paste glue the time not need just can to obtain neat cutting line and mail can never be torn to shreds with shearing when sealing.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Shown in the figure is the constructional drawing of envelope: the 1st, and the end of a thread; The 2nd, non-drying glue layer; The 3rd, protective film; The 4th, be stained with the fine rule of paste.

When selection, should note and to make envelope with the paper that toughness is too high or fiber is too much, otherwise fine rule is difficult for paper is severed.Adopt if having to, then need on folding trace position, to play a perforation line.Should select the anti-higher fine rule of intensity that draws for use.The length of the end of a thread is about 0.5-1cm, and will be hidden in interior fine rule of envelope tongue and envelope tongue after the end of a thread seals will cling.The bonding of non-drying glue and paper is firm.Protective film and non-drying glue do not answer adhesion too tight.

Claims (2)

1, a kind of based on shandardized envelope the design-calculated envelope, scribble non-drying glue on the tongue and carry out lid in envelope when it is characterized in that producing with protective film, be stained with a fine rule of severing the envelope tongue during for unpacking in the folding trace position of envelope tongue.

2, the described fine rule of claim 1 is characterized in that line length is a bit larger tham the folding trace length of envelope tongue, and two the end of a thread do not expose.
