Description

Envelope easy to open

The utility model belongs to a kind of envelope, especially relates to the easy envelope in a kind of Fengkai.

In background technology, there is envelope to use the non-drying glue method of sealing a letter, still, it is not that to seal a letter by all means be exactly that the Kaifeng way is not ideal enough, and example has a kind of backguy Kaifeng method, and the two is difficult to organically combine, and makes higher, difficult the popularizing of inconvenience, cost.

The purpose of this utility model is to provide a kind of Fengkai easy envelope, and it has kept the method for sealing a letter (comprise non-drying glue seal a letter method) of existing envelope, simultaneously, design a kind of with it organic supporting Kaifeng structure and way, realized that easy envelope is easily opened most and simplified, made easily simple, with low cost.Simultaneously, overcome the stamped envelope difficult drawback that breaks a seal, made the stamped envelope penetration and promotion become possibility, can obtain significant saving benefit.Also, two faces of other M.G. pure sulphite paper created advantage for can both developing.

The purpose of this utility model is achieved in that the utility model adds at least one envelope tongue first line of a couplet 〉=an envelope tongue, and adjacent envelope tongue is good to being called, and forms multilayer envelope tongue.When sealing, amount to covering tongue 5,5 places are coated with paste at the envelope tongue, seal tongue 4 in amounting to, and compress with back cover 2 to cement and can seal a letter.During Kaifeng, set about, cut along the limit, perhaps directly tear and get final product sealing tongue 4 in the whole piece with hand with things such as key, nail, button, coin, branches from the neutral gear that forms between interior covering tongue 4 and 5.In addition, also can be shaped on non-drying glue on the covering tongue 5 and on the back cover corresponding 2 with it

With 3.In amounting to towards back cover 2 envelope tongue 4 can tamper seals at the bottom of non-drying glue 3 on 2; Amount to the non-drying glue 6 that covering tongue 5 can be protected covering tongue 5 towards front cover 1.When practical, make covering tongue 5 anti-turnbacks, tightly can seal a letter to glue laminated with 3 place's glue of back cover 2, convenient in the user.In like manner, can on three limits of envelope, make equally, can be made into the incorporate popular stamped envelope of a kind of envelope writing pad; Also the new varieties that can both utilize for two faces developing other M.G. pure sulphite paper have been created advantage.Simultaneously, can also make in the boundary of envelope tongue easily burst at the seams (comprise perforation line, slot line, draw or indentation line and assemble line thereof etc.), help more amounting to and breaking a seal.

Advantage of the present utility model is to make full use of the condition of M.G. pure sulphite paper own and transforms a little, not additional other materials, belong to the inside transformation that envelope itself constitutes, having realized not only that easy envelope is easily opened to simplify most organically combines, and is that two faces of a M.G. pure sulphite paper can both be exploited and created advantage.

In conjunction with the accompanying drawings and embodiments, the utility model is described below:

Fig. 1 is the easy envelope scheme drawing in centre joint formula Fengkai.

Fig. 2 is one of the easy envelope in a side seam formula Fengkai stamped envelope front schematic view.

1～6 expression respectively among the figure: front cover, back cover, back cover non-drying glue district, interior envelope tongue, covering tongue and covering tongue non-drying glue district.

With reference to accompanying drawing: the utility model is sealed up tongue 5 by front cover 1, back cover 2, envelope tongue 4 and connection and is constituted, and can be made into centre joint formula, side seam formula, stamped envelope formula etc., is coated with paste formula or non-drying adhesive type.When sealing a letter, amount to the envelope tongue, envelope tongue 5 places are coated with sticks with paste or 6 pairs of glue 3 of glue compress and get final product.During Kaifeng, start with from the neutral gear that forms between interior covering tongue 4 and 5, cut along the limit with things such as keys, perhaps directly whole piece envelope tongue 4 is torn with hand and get final product, it is easy to reach the Fengkai, the effect of combination.
