【考案の詳細な説明】
防水袋、たとえば乗り物酔いしたときに嘔吐物を入れる
袋には、内面に合成樹脂をラミネートした紙袋があるが
、このような袋は、第３図のごとく、合成樹脂膜１２の
端縁は紙１１の端縁と一致している。[Detailed explanation of the invention] Waterproof bags, such as bags for storing vomit in case of motion sickness, are paper bags whose inner surface is laminated with synthetic resin. The edges of the membrane 12 coincide with the edges of the paper 11.
そして一方のはぎ合わせ部１１ ａを折り返して、それ
へ他方のはぎ合わせ部１１ ｂを接合しているが、この
際、両はぎ合わせ部１１ ａ、１１ ｂ対向面はともに
合成樹脂面であるので、これらはヒートシールが可能で
あるが、折り返しはぎ合わせ部１１ａは、折り返し面が
ともに紙どうしであるため、こ・は糊１４にてお互いを
接着せねばならず、糊１４による接着が不可欠で、手間
が掛る。Then, one spliced portion 11a is folded back and the other spliced portion 11b is joined to it.In this case, since both the facing surfaces of both spliced portions 11a and 11b are synthetic resin surfaces, these Heat sealing is possible, but since the folded surfaces of the folded joint portion 11a are both sheets of paper, they must be adhered to each other with glue 14, and bonding with glue 14 is indispensable and time-consuming. .
しかも、折り返しはぎ合わせ部だけ幅の広い紙を使用せ
ねばならず、−袋当りの紙のコストが高くつく。Moreover, it is necessary to use wider paper only at the folded and seamed portions, which increases the cost of paper per bag.
本考案は上述した欠点が除去され、はぎ合わせ部をヒー
トシールだけで接合できて、糊付けが不要であり、かつ
紙も節約できるようにした防水袋に関する。The present invention relates to a waterproof bag that eliminates the above-mentioned drawbacks, allows the seams to be joined only by heat sealing, eliminates the need for gluing, and saves paper.
しかして本考案の防水袋は、胴紙１の内面に、この胴紙

合成樹脂膜辺部２ａを形成して、この合成樹脂膜辺部２
ａへ、胴紙１における他方のはぎ合わせ用端辺部１ｂを
ピー１〜シールした構造のものとしである。Therefore, the waterproof bag of the present invention has heat-fusible synthetic resin 2a such that an ear portion 3a protruding slightly from the end of one end side 1a of the body 1 for seaming is also formed on the inner surface of the body 1. and the one end side 1a of the paper shell.
A synthetic resin membrane side portion 2a having an ear portion 3b that overlaps with the ear portion 3a is also formed on the outer surface of the synthetic resin membrane side portion 2.
Figure a shows a structure in which the other seaming end portion 1b of the trunk paper 1 is sealed.
本考案の袋は上述した構造のもので、胴紙１の内面に形
成した合成樹脂膜２ａには、胴紙１の一端縁から延出す

外面には、同じく耳部３ｂがはみ出す合成樹脂膜辺部２
ｂが形成されているので、胴紙の他辺部１ｂを合成樹脂
膜辺部２ｂへ重ねて加熱すれば、別紙の両はぎ合わせ端
辺どうじが一挙にヒートシールされる。The bag of the present invention has the above-mentioned structure, and the synthetic resin film 2a formed on the inner surface of the paper shell 1 has an ear portion 3a extending from one end edge of the paper shell 1. On the outer surface of one end, there is a synthetic resin membrane side portion 2 from which the ear portion 3b also protrudes.
b is formed, so if the other side 1b of the body paper is overlapped with the synthetic resin membrane side 2b and heated, the edges of the two joined sheets of paper are heat-sealed at once.
したがって、合成樹脂耳部のない従来のものと異なり、
糊付けする必要はなく、その工程が省かれるとともに、
胴紙の折り返し代が不要で、製袋原紙を節約でき、製袋
コストの低減を期せる。Therefore, unlike conventional products that do not have synthetic resin ears,
There is no need to glue, that process is omitted, and
There is no need to fold the body paper, saving base paper for bag making and reducing bag making costs.
しがもはぎ合わせ部における袋の内側となる部分の端縁
は、互いに重合している合成樹脂耳部３ ａ 、３ ｂ
によって覆われているので、袋の中の水分によって内側
はぎ合わせ部が湿潤して剥離するようなことはなく、安
全に使用できるという利点がある。The edges of the inner part of the bag at the seam part are made of synthetic resin ears 3 a and 3 b that are overlapped with each other.
Since the inner seam is covered with water, moisture in the bag will not cause the inner seam to become wet and peel off, giving it the advantage of being safe to use.
