Description

本発明は、袋部にレター基材が収容される製袋レターパックに関するものである。   The present invention relates to a bag making letter pack in which a letter base material is accommodated in a bag portion.

一般的な封筒は、フラップ部が封緘されており、受取人は、周囲４辺の内１辺の端縁部を切り取って内容物を取り出す。
この場合に、ハサミやレターオープナーを別途用意することが一般的であるが、例えば、知人からの私信ではなく、ＤＭのような企業の販促用封筒の場合には、開封しづらいだけで、開封もされずに、即座にゴミ箱行きとなってしまうことがある。
そこで、端縁部にミシン目を設けたり、開封用ジッパーを設けておく方法が提案されている（例えば、特許文献１）。 In a general envelope, a flap portion is sealed, and a recipient cuts out an edge portion of one of the four sides and takes out the contents.
In this case, it is common to prepare scissors and letter openers separately. For example, in the case of a company promotional envelope such as DM, it is difficult to open and it is not easy to open. Instead, it can go to trash instantly.
In view of this, a method has been proposed in which a perforation is provided at the edge or an opening zipper is provided (for example, Patent Document 1).

これら開封用ミシン目や開封用ジッパーは、ミシン目の形状やカット比を適宜選定すれば、ある意味でいくらでも開封しやすくすることは可能であるが、開封しやすいことは、逆に、配送時等に意図しないタイミングで勝手に開封してしまう、といった問題が想定される。このため、必ずしも、開封しやく設定できなかった。開封した状態で届けば、逆の意味で受け取った側としては、不安な気持ちになるからである。   These opening perforations and opening zippers can be easily opened as much as possible by selecting the perforation shape and cut ratio as appropriate. There is a problem that the package is unintentionally opened at an unintended timing. For this reason, it was not always possible to set it open easily. This is because if it is delivered in an opened state, it will be uneasy for the recipient in the opposite sense.

図２は、従来の製袋レターパックの一例を示す図である。
従来の製袋レターパック２０は、袋下基材２１と、レター基材２４と、袋上基材２２の３枚の基材が、左辺側で接着剤層２３−１、２３−２により、それぞれ貼り合せられており、袋上基材２２の右辺側のフラップ部２２ｂの裏面に、両面テープ等の封着部２７が設けられていた。また、袋上基材２２には、ミシン目を有する開封用ジッパー部２６が形成されていた。 FIG. 2 is a view showing an example of a conventional bag making letter pack.
In the conventional bag making letter pack 20, the three base materials of the bag base material 21, the letter base material 24, and the bag base material 22 are formed on the left side by the adhesive layers 23-1 and 23-2. Each of them was bonded, and a sealing portion 27 such as a double-sided tape was provided on the back surface of the flap portion 22b on the right side of the bag base material 22. Moreover, the zipper part 26 for opening which has a perforation was formed in the base material 22 on a bag.

従来の製袋レターパック２０は、上述した開封用ジッパー部２６の破れ難さと開封しやすさの問題の他に以下のような問題があった。
２枚目のレター基材２４の部分は、接着剤層２３側を割りミシン目で分離して、引き抜くような形態になる。このため、開封用ジッパー部１２の中央くらいの位置に、レター基材２４のエッジがくるように設計して、引き抜きやすくしているものの、やはり、取り出しやすさに問題が残る。
また、冊子を手封入しようとすると、確実にレター基材２４より下側又は上側（矢印Ｃ又はＤ参照）に封入することは困難であった。 The conventional bag making letter pack 20 has the following problems in addition to the above-described problems of tearing of the opening zipper portion 26 and ease of opening.
The portion of the second letter base material 24 has a form in which the adhesive layer 23 side is separated by a perforation and pulled out. For this reason, the edge of the letter base material 24 is designed so that the edge of the letter base 24 comes to the position of the center of the opening zipper portion 12 so that it can be easily pulled out.
Further, when trying to enclose a booklet by hand, it is difficult to reliably enclose the booklet below or above the letter base material 24 (see arrow C or D).
