Description

本発明は、封筒に関し、特に、ジッパーで簡単に開封することができる開封用ジッパー付き封筒に関する。 The present invention relates to envelopes, and more particularly to envelopes with an opening zipper that can be easily opened with a zipper.

封筒を簡単に開封できるように開封部に開封用ジッパーを形成した封筒が知られている（特許文献１、２参照）。 Envelopes in which an opening zipper is formed in an opening portion so that the envelope can be easily opened are known (see Patent Documents 1 and 2).

図３は従来の開封用ジッパー付き封筒の１例を示し、ダイレクトメール、カタログなどを送付する際に開封用ジッパー付き封筒が利用されている封筒は、重ねた表紙１と裏紙２の下部が閉じられるとともに、上部は開放されてダイレクトメールあるいはカタログなどの収納物を入れる開口部３が形成されている。 FIG. 3 shows an example of a conventional envelope with a zipper for opening. For an envelope in which an envelope with a zipper for opening is used when sending direct mail, a catalog, etc., the lower part of the front cover 1 and the back cover 2 are overlapped. At the same time as being closed, the upper part is opened to form an opening 3 for storing items such as direct mail or a catalog.

表紙１の上部には、幅方向の折曲線４に沿って折り曲げることにより開口部３を閉じて封緘する封緘片５が延設されている。封緘片５の裏紙２側の端辺側に接着剤が塗布されて接着層６が形成され、接着層６の表面には剥離シート７が貼られている。 At the upper part of the cover 1, a sealing piece 5 that closes and seals the opening 3 by bending along a folding curve 4 in the width direction is extended. An adhesive is applied to the edge side of the sealing piece 5 on the backing paper 2 side to form an adhesive layer 6, and a release sheet 7 is attached to the surface of the adhesive layer 6.

封緘片５の中央部には、幅方向に引き裂いて封筒を開封する開封用ジッパー８が形成されている。開封用ジッパー８は、複数の切込みが２列に平行に配列される切り離し線９を備えている。 An opening zipper 8 is formed at the center of the sealing piece 5 to tear the envelope in the width direction to open the envelope. The opening zipper 8 includes a separating line 9 in which a plurality of notches are arranged in parallel in two rows.

封筒は、図４（ａ）に示すように、開口部３から収納物を入れた後、封緘片５の剥離シート７を剥がして接着層６を露出させ、封緘片５を折曲線４に沿って裏紙２側に折り曲げて裏紙２に接着層６を接着させて封緘する。 As shown in FIG. 4A, the envelope is formed by inserting the stored material through the opening 3 and then peeling off the release sheet 7 of the sealing piece 5 to expose the adhesive layer 6 and folding the sealing piece 5 along the folding curve 4. The adhesive layer 6 is attached to the backing paper 2 by bending it toward the backing paper 2 and sealing it.

封筒を開けるには、図４（ｂ）に示すように、開封用ジッパー８を切り離し線９に沿って引っ張り上げていき封筒から分離して開封する。 To open the envelope, as shown in FIG. 4B, the opening zipper 8 is separated from the envelope by pulling it up along the disconnection line 9 and opening the envelope.

しかしながら、従来の開封用ジッパー付き封筒は、開封用ジッパー８が封緘片５の中央に形成されているため、開封用ジッパー８を引き上げる際に、封緘片５が浮き上がるためにきれいに切断できないという欠点があった。 However, the conventional envelope with an opening zipper has a drawback that since the opening zipper 8 is formed in the center of the sealing piece 5, when the opening zipper 8 is pulled up, the sealing piece 5 is lifted and cannot be cut cleanly. there were.

そこで、本発明は、ジッパーを引き上げる際に封緘片が浮き上がることなくきれいに切断できる開封用ジッパー付き封筒を提供するものである。 Therefore, the present invention provides an envelope with an opening zipper that can be cut cleanly without lifting the seal piece when the zipper is pulled up.

本願請求項１の発明は、重ねた表紙と裏紙の３辺が閉じられ、上部は開放されて開口部が形成され、表紙の上部には幅方向の折曲線に沿って裏紙側へ折り曲げて開口部を閉じて封緘する封緘片が延設され、封緘片の裏紙側には平行の２本の切り離し線を有する開封用ジッパーが形成されるとともに、表面に剥離シートが貼られた接着層が形成されている開封用ジッパー付き封筒において、
開封用ジッパーの平行の２本の切り離し線のうち一方の切り離し線が表紙の上部の前記幅方向の折曲線に形成されており、
前記封緘片は、前記表紙の上部に延設され前記折曲線と同じ長さ及び前記２本の切り離し線の間隔と同じ高さの長方形部分と、前記長方形部分の上辺に延設され前記折曲線より短い長さの下底及び該下底より短い長さの上底を有する等脚台形部分を有しており、
前記２本の切り離し線のうち他方の切り離し線が前記下底に形成されており、
前記上辺の前記下底より左側の部分と前記長方形部分の左辺によって前記開封用ジッパーの左端に指で摘まむことができる摘まみ部が形成されており、
前記上辺の前記下底より右側の部分と前記長方形部分の右辺によって前記開封用ジッパーの右端に指で摘まむことができる摘まみ部が形成されていることを特徴とする開封用ジッパー付き封筒である。 In the invention of claim 1 of the present application, the three sides of the overlapped front and back covers are closed, the upper portion is opened to form an opening, and the upper portion of the front cover is bent toward the back paper along a folding curve in the width direction. A sealing piece that closes the opening and seals is extended, and an opening zipper with two parallel separating lines is formed on the backing paper side of the sealing piece, and a release sheet is attached to the surface. In a layered opening zippered envelope
One of the two parallel separation lines of the opening zipper is formed on the fold curve in the width direction at the top of the cover .
The sealing piece extends over the upper part of the cover and has a rectangular portion having the same length as the folding curve and the same height as the distance between the two separating lines, and the folding curve extending over the upper side of the rectangular portion. It has an isosceles trapezoidal portion with a shorter bottom and an upper bottom shorter than the bottom.
The other disconnection line of the two separation lines is formed on the lower base.
A pinch portion that can be picked with a finger is formed at the left end of the opening zipper by the portion on the left side of the lower bottom of the upper side and the left side of the rectangular portion.
An envelope with an opening zipper, characterized in that a pinch portion that can be picked with a finger is formed at the right end of the opening zipper by a portion on the right side of the lower bottom of the upper side and a right side of the rectangular portion. is there.

本発明の開封用ジッパー付封筒は、封緘片の幅方向の折曲線に開封用ジッパーの一方の切り離し線が形成されることにより開封用ジッパーを引っ張り上げても封緘片が浮き上がらないので、開封用ジッパーが切り離し線に沿って封筒から分離して簡単にきれいに開封することができる。
また、開封用ジッパーには、両側に摘まみ部が形成されているので、左右の利き手に応じていずれか一方の好みの摘まみ部を摘まんで開封用ジッパーを引き上げて容易に分離することができる。 The envelope with an opening zipper of the present invention is for opening because the sealing piece does not rise even if the opening zipper is pulled up because one of the opening zipper's separating lines is formed on the folding curve in the width direction of the sealing piece. The zipper separates from the envelope along the break line and can be easily and neatly opened.
In addition, since the opening zipper has knobs formed on both sides, it is possible to pick one of the favorite knobs according to the left and right dominant hands and pull up the opening zipper for easy separation. it can.
