【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、封緘片に前もって接着剤を施した袋であって
、離型紙を貼着せずに積重ねても重ねた状態でばらけす
、使用時１枚ずつ剥がして使用することのできる封緘片
付袋に関する。本発明は封筒などの紙製の袋、プラスチ
ック製の袋などに適用される。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a bag whose sealing piece is pre-applied with adhesive, and which does not come apart in the stacked state even if it is stacked without pasting release paper. This bag relates to a bag with a seal that can be peeled off one by one and used. The present invention is applied to paper bags such as envelopes, plastic bags, and the like.
袋口から延出する封緘用の舌片である封緘片に前もって
粘着剤や接着剤を施した袋は、使用にあたり１枚ずつ粘
着剤を塗布する手間が省けるため広く使用されている。Bags in which adhesive or adhesive is applied in advance to the sealing tongue extending from the bag opening are widely used because it saves the effort of applying adhesive to each bag before use.
しかし、粘着剤はそのまま放置するとほこり等を吸着し
て粘着力が低下し、また、不本意な部位に粘着して使用
に耐えなくなり、被粘着物を汚染する。そのため、粘着
剤を施した部位を離型紙で覆って粘着剤を保護している
。However, if the adhesive is left as it is, it will attract dust and the like, reducing its adhesive strength, and will also stick to unwanted areas, making it unusable and contaminating the object to which it is adhered. Therefore, the area where the adhesive is applied is covered with release paper to protect the adhesive.
しかしながら、製造にあたり封緘片の表面に離型紙を貼
着していく作業は手間を要し、結果的に製品のコストを
上昇させる。一方、使用者の立場から見ると封緘する度
に離型紙を剥がすのは面倒であり、剥離後の離型紙が散
乱する。特に商品の包装に使用されるプラスチック袋に
おいては使用枚数も多いため、離型紙を剥離する手間と
散乱する離型紙の処理は無視しがたいものである。However, during manufacturing, the work of attaching release paper to the surface of the sealing piece requires time and effort, resulting in an increase in the cost of the product. On the other hand, from the user's perspective, it is troublesome to peel off the release paper every time the product is sealed, and the release paper is scattered after being peeled off. In particular, since the number of plastic bags used for packaging products is large, the effort of peeling off the release paper and the disposal of scattered release paper cannot be ignored.
更にプラスチックのように表面の平滑性に優れた素材か
らなる袋は、袋の外面同士が滑りやすく、束ねた場合に
散乱しがちで取扱い難い欠点があった。Furthermore, bags made of materials with excellent surface smoothness, such as plastic, have the disadvantage that the outer surfaces of the bags tend to slip on each other, and when bundled, they tend to scatter and are difficult to handle.
そこで、離型紙を使用せずに封緘片に施した粘着剤を保
護し、しかも収納・保存時にブロック化して散乱しない
封緘片付袋が求められていた。Therefore, there was a need for a bag with a sealing piece that protects the adhesive applied to the sealing piece without using release paper, and that does not block and scatter during storage or storage.
本発明は上記課題を解決することを目的とし、その構成

程度に、封緘片表面に離型処理が施されていることを特
徴とする。The present invention aims to solve the above-mentioned problems, and has a configuration in which a sealing piece extends from the bag opening, and the bag opening is sealed by folding the sealing piece and adhering it to the packaging body. Stack multiple bags of the same shape with adhesive applied to them, apply release paper only to one bag at one end, and apply release paper to the extent that the adhesive will not be transferred to the surface of the sealing piece even if you peel them off one by one during use. , characterized in that the surface of the sealing piece is subjected to mold release treatment.

It is a laminate of these or a laminate of these and other materials. The shape may be any shape as long as it extends from the bag opening on the surface of the bag, and a sealing piece for covering and pasting the bag surface with the bag opening as a fold line extends.
本発明にあっては、この封緘片の表面に粘着剤を施す。In the present invention, an adhesive is applied to the surface of this sealing piece.

もある。Furthermore, a release process is performed in which a release agent such as silicone is applied thinly to the surface of the sealing piece. The amount of release agent to be applied should be determined so that when the bags treated in this way are stacked, the adhesive on the surface of the sealing piece will stick to the surface of the sealing piece of the adjacent bag, but when the bags are peeled off one by one, the adhesive will be removed. Apply to the extent that it does not transfer onto the surface of the sealing piece. Therefore, the adhesive strength of the adhesive and the amount of release agent to be applied are significantly influenced by the material of the bag material. Since paper is a material to which adhesive is easily transferred, it is necessary to apply a sufficient amount of release agent. Plastics, especially olefins, have properties that make it difficult for mold release agents to be transferred, so do not apply a mold release agent (or if you choose an adhesive, the adhesive on the surface of the sealing piece may not be transferred to the surface).

方法が挙げられる。Furthermore, in the case of plastic bags, by microscopically roughening the surface of the sealing piece, affinity with the adhesive can be increased and transfer to the surface of the sealing piece can be prevented. Examples of means for microscopically roughening the surface include methods using chemical treatments such as imine-based chemical treatments, methods using corona discharge, ultraviolet irradiation, and the like.
本発明は、封緘片表面に粘着剤を施した同形の袋を複数

く１枚ずつ離して使用することができる。In the present invention, a plurality of bags of the same shape with adhesive applied to the surface of the sealing piece are stacked, and only the adhesive of the bag sealing piece that is located at the bottom layer and whose surface is exposed is protected with release paper, and the stacked adhesive A release treatment is applied between the adhesive and the surface of the sealing piece to prevent the adhesive from being transferred to the surface of the sealing piece when peeled off one by one during use. be. That is,
By applying appropriate adhesive treatment, even if a plurality of bags are stacked and bundled, the bags can be separated and used one by one without the adhesive being transferred to the surfaces of adjacent bags.
また、保存時容袋が粘着剤によりブロック化してばらけ
難い作用も有する。In addition, the storage bag is blocked by the adhesive and has the effect of being difficult to unravel.

離型紙であり、封筒１の束の裏側に１枚だけ貼着した。FIG. 1 is a perspective view of a bundle of paper envelopes, and FIG. 2 is a partially enlarged explanatory view of FIG. 1. 1 is an envelope, 2 is a sealing piece, and 3 is an adhesive applied to the surface of the sealing piece 2. A thin layer of silicone resin 4 was applied to the surface of the sealing piece 2 as a mold release treatment. Reference numeral 5 denotes a release paper, and only one sheet was pasted on the back side of the bundle of envelopes 1.
第１図においては説明の都合上離型紙の幅を封筒より大
きくしたが、封筒幅と同一または粘着剤を覆うことがで
きる範囲で封筒幅よりやや狭いことが好ましい。In FIG. 1, the width of the release paper is shown to be larger than the envelope for convenience of explanation, but it is preferably the same as the envelope width or slightly narrower than the envelope width within a range that can cover the adhesive.

表面に転写しなかった。In FIG. 2, the adhesive layer and the silicone resin layer are extremely enlarged for explanation. Since the adhesive 3 was in contact with the surface of the sealing piece 2 via the silicone resin 4, it was easily peeled off when peeled off one by one during use, and the adhesive was not transferred to the surface of the sealing piece.
しかもシリコン樹脂４は薄く施したため、シリコン樹脂

重ね合わせると互いに一体化して特に環ゴムなどで固定
しなくとも２０枚の束は解けることがなかった。Moreover, since the silicone resin 4 was applied thinly, some adhesive leached through the silicone resin, and when 20 envelopes were stacked on top of each other, they became integrated, and even if they were not fixed with a rubber ring, a bundle of 20 envelopes could be assembled. I couldn't solve it.

剤部分に離型紙５を貼着して製造した。In the envelopes of the present invention, the envelopes were shifted and stacked so that about two-thirds of the surface of the sealing piece 2 was exposed, and silicone resin 4 was applied thinly to this surface. Next, the envelopes were shifted and stacked one on top of the other so that about 1/2 of the surface of the sealing piece 2 was exposed, and the adhesive 3 was applied to this surface. Immediately after drying, 20 sheets were stacked one on top of the other, and a release paper 5 was attached to the exposed adhesive portion to produce a product.
