Description

【０００１】
【発明の属する技術分野】
本発明は、可撓性を有するシート体によって形成された口部材付き容器に関し、特に、側方にガセットを備えてなる口部材付き容器に関するものである。
【０００２】
【従来の技術】
従来、図５の如く、可撓性を有するシート体からなる容器本体５１と、該容器本体５１に取り付けられた口部材５２とを備え、正面壁５３と、正面壁５３に対向する背面壁５４と、正面壁５３と背面壁５４とを側方にて連結し且つ容器本体５１の内側へ折り込まれた左右一対のガセット５５，５６とから、前記容器本体５１が構成されてなる口部材付き容器が公知である。
【０００３】
かかる容器本体５１は、正面壁５３、背面壁５４、及び両ガセット５５，５６が各々別々のシート体で構成されており、合計４枚のシート体の側縁部の内面同士がヒートシールで接着されることにより、袋状に形成されたものである。
【０００４】
このように形成された容器は、容器本体５１内に飲料等が充填されて商品として陳列されるので、容器本体５１には、その商品名や模様等の印刷が施されており、また、ガセット５５，５６が設けられているので、自立状態で陳列させることができる。
【０００５】
【発明が解決しようとする課題】
しかるに、これらの印刷は、主に容器本体５１の正面壁５３に施されており、また、側方のガセット５５，５６に印刷を施しているものでも、その印刷は、正面壁５１の印刷と連続性がなく、ガセット５５，５６のみで完結する単純模様の印刷であった。
従って、正面壁５３を前方にして容器を陳列し、その容器を斜め前方から見ると、印刷付きの正面壁５３の隣に別の印刷がされたガセット５５，５６が見えることになり、容器のデザインが一体感にかけることになる。
【０００６】
そこで本発明は、上記従来の問題点に鑑みてなされたもので、デザインに一体感と立体感とを持たせることができる口部材付き容器を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明は、上記課題を解決すべくなされたものであり、本発明に係る口部材付き容器は、可撓性を有するシート体からなる容器本体（１）と、該容器本体（１）に取り付けられた口部材（２）とを備え、前記容器本体（１）には、正面壁（３）と該正面壁（３）に対向する、該正面壁より幅広の背面壁（４）とを側方にて連結し且つ、容器本体（１）の内側へ折り込まれたガセット（５）が設けられてなる口部材付き容器において、正面壁（３）と背面壁（４）とガセット（５）とは、少なくとも正面壁（３）に相当する箇所からガセット（５）に相当する箇所にかけて予め印刷（１０）が連続的に施された一枚のシート体で構成されており、背面壁（４）の側縁部（４ａ）の内面とガセット（５）の内面とが、正面壁（３）の側縁部（３ａ）から背面壁（４）の側縁部（４ａ）までの幅よりも小さいシール幅でヒートシールにより接着され、且つ、正面壁（３）の側縁部（３ａ）の内面とガセット（５）の内面とが接着されていないことを特徴とする。
【０００８】
本発明の口部材付き容器にあっては、少なくとも正面壁３に相当する箇所からガセット５に相当する箇所にかけて予め印刷１０が連続的に施された一枚のシート体から正面壁３と背面壁４とガセット５が構成されているので、例えば、斜め前方から見た場合には、正面壁３の印刷１０とガセット５の印刷１０とが一連のデザインとして映る。また、容器本体１のデザインが、正面壁３から側方のガセット５側に回り込むこととなるので、奥行きのあるデザインとなる。
【０００９】
しかも、正面壁３と背面壁４とガセット５とを一枚のシート体から構成して、少なくとも正面壁３に相当する箇所からガセット５に相当する箇所にかけて予め印刷１０を施した一枚のシート体を使用しているので、互いのシート体の位置合わせを厳密に制御して、その境界部における印刷の整合性をとるという必要もなくなる。
【００１０】
更に、背面壁（４）が正面壁より幅広に構成されているので、正面壁３に接触することなく、背面壁（４）の側縁部（４ａ）の内面とガセット（５）の内面との接着のみを簡便且つ確実に行うことができ、印刷１０が連続的に施されている正面壁３とガセット５との境界部に接着部がないので、飲料等の充填物を容器本体１内に充填した状態で正面側から見ると、接着部でガセット５の印刷１０が死角になるということがない。
【００１１】
【発明の実施の形態】
以下、本発明の一実施形態について図面に従って説明する。
本実施形態にかかる口部材付き容器は、図１に示す如く、飲料等の液体やゼリー等の粘体等の被収容物を充填可能に密封状の袋状に形成されてなる容器本体１と、該容器本体１の上端部１ａに取り付けられて、前記被収容物を取り出すための口部材２とからなる。
【００１２】
前記容器本体１は、一枚の可撓性を有するシート体から構成され、図１及び図２の如く、正面壁３と、正面壁３に対向する背面壁４と、正面壁３と背面壁４とを側方にて連結し且つ容器本体１の内側へ折り込まれた左右一対のガセット５，５とからなる。
【００１３】
また、前記背面壁４の両側縁部４ａ，４ａの内面と両ガセット５，５の一方の側縁部５ａ，５ａの内面とは、シール幅Ｗ３，Ｗ４でヒートシールにより接着され、接着された箇所にシール部６，６が形成されてなる。また、正面壁３の両側縁部３ａ，３ａと両ガセット５，５の他方の側縁部５ｂ，５ｂの内面とは接着されずに離間してなる。更に、正面壁３の幅Ｗ１は、背面壁４の幅Ｗ２よりも両シール部６，６の幅Ｗ３，Ｗ４以上小さく、Ｗ１＜Ｗ２−（Ｗ３＋Ｗ４）の関係を有してなる。即ち、正面壁３とガセット５との境界部７が、左右共に、各々のシール部６よりも内側に位置してなる。
【００１４】
更に、容器本体１には図１及び図３のように、正面壁３から両ガセット５，５にかけて印刷１０が連続的に施されてなる。より具体的には、一方のガセット５のシール部６から正面壁３を介して他方のガセット５のシール部６まで印刷１０が連続して施されてなる。
【００１５】
尚、シート体は、例えば、印刷１０が施されたポリエチレンテレフタレート等のポリエステルフィルムやポリアミドフィルム等と、必要によりアルミホイルやエチレンビニルアルコール共重合体フィルムや無機物を蒸着したフィルム等のガスバリアー性フィルムとを積層した基材フィルムの内面に、ポリエチレンやポリプロピレン等の熱融着性樹脂の層を形成した積層フィルムを採用することができる。また、その他の合成樹脂性フィルム等の任意の材質を使用することもできる。何れにしても、内面側がヒートシール可能で内部に飲料やその他目的の被収納物を収納可能なものであればよい。
【００１６】
一方、前記口部材２は、容器本体１に取り付けられた取付部８と、該取付部８の上端側の注出口部とからなり、該注出口部には着脱自在な蓋体９が螺合されている。そして、蓋体９を取り外すことにより、容器本体１内の被収容物を注出口部から取り出すことができるようになっている。また、口部材２は、容器本体１の内面と熱融着可能な合成樹脂から成型により形成されてなる。
【００１７】
また、上記の如く構成される容器本体１は、例えば、以下の如く製造される。即ち、一枚のシート体のうちの正面壁３と両ガセット５，５に相当する箇所に、予め商品のメインデザインを表す印刷１０を施しておき、そのシート体の端部同士（図２においてガセット５の一方の側縁部５ａと、背面壁４の側縁部４ａに相当する部分）を重ね合わせて筒状に形成し、該筒状のシート体を折り畳んで扁平状に形成する。この際、予め一枚のシート体に印刷１０を施しているので、折り畳んで正面壁３とガセット５とを区画形成しても、両ガセット５，５と正面壁３との間の印刷１０の連続性を自動的且つ確実に確保できる。
【００１８】
そして、背面壁４の両側縁部４ａ，４ａと両ガセット５，５とを、図２の一点破線のように、上下のシールバー２０，２０でヒートシールにより接着するが、正面壁３の幅Ｗ１が背面壁４の幅Ｗ２よりも小さいので、シールバー２０，２０が正面壁３に接触することなく、背面壁４とガセット５との接着のみ確実に行うことができる。
【００１９】
更に、ヒートシールで下端部１ｂにおけるシート体の内面同士を接着することにより袋状の容器本体１を作成し、次に、該容器本体１の上端部１ａをヒートシールで封着する際に、同時に口部材２の取付部８をシート体の内面側に挿入して取り付ける。
【００２０】
このような構成からなる口部材付き容器の容器本体１内に飲料等の被収容物を充填すると、図３の如く容器本体１が膨出した状態になる。また、側方にガセット５，５が形成されてなるので、陳列した際の自立性が確保できる。
【００２１】
そして、陳列した状態では、両ガセット５，５にも正面壁３と一連の印刷１０が施されているので外観上目立ちやすく、また、正面壁３に対して背面壁４が幅広で且つガセット５の印刷１０がシール部６まで施されているので、ガセット５の印刷１０も前方から確実に認識できる。
【００２２】
しかも、正面壁３からガセット５にかけて印刷１０が連続的に施されてなるので、正面壁３の印刷１０とガセット５の印刷１０とが一連のデザインとして映り、正面壁３とガセット５との境界部７でデザインが途切れることがなく、一体感のあるデザインが得られる。同時に、容器本体１のデザインが、正面壁３から側方のガセット５側に回り込むこととなるので、デザインに奥行き感、立体感が得られる。
【００２３】
更に、正面壁３の両側縁部３ａ，３ａの内面と両ガセット５，５の内面とを接着しないことにより、正面壁３とガセット５とで一つの連続面を形成できる。従って、境界部７でガセット５の印刷１０が死角になりにくく、正面壁３からガセット５にかけてのデザインが視覚的にも途切れることがないので、より一層デザイン上の連続性と一体感を高めることができ、且つ立体感も高まる。
【００２４】
従って、正面壁３のみに印刷１０が施されている場合や、ガセット５の印刷１０が正面壁３の印刷１０と別個独立で不連続である場合に比して、商品として陳列したときのインパクト、買い手へのアピール度合いを高めることができ、訴求効果を向上させることができるのである。
【００２５】
尚、本実施形態では、四本の横線を印刷１０の一例として説明してなるが、印刷１０の模様等はこれに限定されず、文字等の印刷であってもよく、商品イメージの図柄やイラストと風景等の写真等を組み合わせたものでもよい。また、印刷１０がガセット５のシール部６まで達していなくとも、また、背面壁４まで連続して印刷されていてもよく、正面壁３から境界部７を介してガセット５まで印刷１０が連続的に施されていればよい。尚、背面壁４には、被収容物や使用方法等の説明や注意書き等の表示がなされることが一般的である。
【００２６】
また、正面壁３の両側縁部３ａ，３ａと両ガセット５，５とを接着して、互いの境界部７に接着部を形成しても請求項１の範囲内である。但し、接着部によって連続的な印刷１０が裏表に分かれるので、正面若しくは斜め前方から見たときにガセット５側の印刷１０が接着部の死角になりやすいため、上記の如く、接着部を設けないことが好ましい。また、接着部を形成した場合には、接着部の幅を狭くする方が好ましい。
【００２７】
また、上記実施形態では、一枚のシート体から容器本体１を構成してなるが、正面壁３と両ガセット５，５とを一枚のシート体で形成し、背面壁４をこのシート体とは別のシート体から構成してもよい。更に、印刷１０は、視認性向上の観点から、上記実施形態の如く、正面壁３から左右一対のガセット５，５にかけて連続的に施されていることが好ましいが、何れか一方のガセット５にかけて連続的に施されていれば本発明の意図する範囲内である。かかる場合、印刷１０が正面壁３から連続的に施された側のガセット５と正面壁３とを少なくとも一枚のシート体から構成すればよい。ガセット５と正面壁３と別々のシート体から構成した場合に、正面壁３とガセット５との間に印刷１０の連続性を持たせるには、正面壁３の側縁部３ａとガセット５の側縁部５ｂとの貼り合わせ位置を厳密に制御しなければならないためである。尚、ガセット５が片側のみ設けられていても本発明の範囲内である。
【００２８】
【発明の効果】
以上のように、本発明の口部材付き容器は、正面壁からガセットにかけての連続印刷により、正面壁からガセットにかけて一体感のあるデザインが得られ、且つ、デザインに奥行きを持たせることができ、立体感のあるデザインを得ることができる。
【００２９】
従って、従来は、正面壁のみの印刷で平面的なデザインであったのに比して、商品として陳列したときのインパクト、買い手へのアピール度合いを高めることができ、訴求効果を向上させることができるという効果を奏する。
【００３０】
しかも、予め一枚のシート体に正面壁からガセットにかけての印刷を一体的に施しておくことができるので、正面壁とガセットとを別々のシート体から構成する場合のように、互いのシート体の位置合わせを厳密に制御して、その境界部における印刷の整合性をとるという必要もなくなり、容器形成後においても、ガセットと正面壁との間の印刷の連続性を自動的且つ確実に確保できるのである。
【００３１】
特に、請求項２記載の如く、正面壁の側縁部の内面とガセットの内面とを接着しないことにより、正面壁とガセットとで一つの連続面を形成でき、正面壁からガセットにかけてのデザインが視覚的にも途切れることがなく、より一層デザイン上の連続性と一体感を高めることができ、且つ立体感も高まる。

BACKGROUND OF THE INVENTION
The present invention relates to a container with a mouth member formed by a flexible sheet, and more particularly to a container with a mouth member provided with a gusset on the side.
[0002]
[Prior art]
Conventionally, as shown in FIG. 5, a container main body 51 made of a flexible sheet body and a mouth member 52 attached to the container main body 51 are provided, and a front wall 53 and a rear wall 54 facing the front wall 53 are provided. And a pair of left and right gussets 55, 56 that are connected to the front wall 53 and the back wall 54 at the side and folded inside the container body 51. Is known.
[0003]
In the container main body 51, the front wall 53, the back wall 54, and both gussets 55 and 56 are each composed of separate sheet bodies, and the inner surfaces of the side edges of the total of four sheet bodies are bonded together by heat sealing. By doing so, it is formed in a bag shape.
[0004]
Since the container formed in this way is displayed as a product filled with beverages or the like in the container body 51, the container body 51 is printed with the product name, pattern, etc., and the gusset Since 55 and 56 are provided, they can be displayed in a self-supporting state.
[0005]
[Problems to be solved by the invention]
However, these printings are mainly performed on the front wall 53 of the container main body 51, and even if printing is performed on the side gussets 55 and 56, the printing is the same as the printing on the front wall 51. There was no continuity, and the printing was a simple pattern completed only with gussets 55 and 56.
Therefore, when the container is displayed with the front wall 53 facing forward, and the container is viewed obliquely from the front, another printed gusset 55, 56 is seen next to the printed front wall 53, and the container The design will give a sense of unity.
[0006]
Then, this invention is made | formed in view of the said conventional problem, and makes it a subject to provide the container with an opening member which can give a design a sense of unity and a three-dimensional effect.
[0007]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and a container with a mouth member according to the present invention is attached to a container body (1) made of a flexible sheet body and the container body (1). The container body (1) is provided with a front wall (3) and a rear wall (4) wider than the front wall facing the front wall (3). In the container with a mouth member which is connected at the side and is provided with a gusset (5) which is folded inside the container body (1), the front wall (3), the back wall (4), and the gusset (5) Is composed of a single sheet body on which printing (10) is continuously applied in advance from at least a portion corresponding to the front wall (3) to a portion corresponding to the gusset (5), and the back wall (4). The inner surface of the side edge (4a) and the inner surface of the gusset (5) are connected to the side edge (3a) of the front wall (3). To the side edge (4a) of the back wall (4) by a heat seal with a smaller seal width, and the inner surface of the side edge (3a) of the front wall (3) and the gusset (5) The inner surface is not bonded .
[0008]
In the container with a mouth member of the present invention, the front wall 3 and the rear wall are formed from a single sheet body in which printing 10 is continuously applied in advance from at least a portion corresponding to the front wall 3 to a portion corresponding to the gusset 5. Since 4 and the gusset 5 are configured , for example, when viewed obliquely from the front, the print 10 on the front wall 3 and the print 10 on the gusset 5 appear as a series of designs. Moreover, since the design of the container main body 1 goes around from the front wall 3 to the side gusset 5 side, the design is deep.
[0009]
Moreover, constitute the front wall 3 and rear wall 4 and the gusset 5 from a single sheet, a sheet of which has been subjected to pre-print 10 toward an area corresponding to the gusset 5 from the point corresponding to at least the front wall 3 sheets Since the body is used, it is not necessary to strictly control the alignment of the sheet members to achieve printing consistency at the boundary.
[0010]
Furthermore , since the back wall (4) is configured to be wider than the front wall, the inner surface of the side edge (4a) of the back wall (4) and the inner surface of the gusset (5) without contacting the front wall 3 adhesive only can be done easily and reliably, and since the printing 10 is not adhesive part in the boundary portion between the front wall 3 and the gusset 5 which is continuously subjected, filling the container body 1 such as beverage When viewed from the front side in a state where the gusset 5 is filled, the print 10 of the gusset 5 does not become a blind spot at the adhesive portion.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The container with a mouth member according to the present embodiment, as shown in FIG. 1, a container body 1 formed in a sealed bag shape so as to be able to be filled with an object such as a liquid such as a beverage or a viscous material such as a jelly, It is attached to the upper end portion 1a of the container body 1 and comprises a mouth member 2 for taking out the object.
[0012]
The said container main body 1 is comprised from the sheet | seat body which has one sheet of flexibility, and as shown in FIG.1 and FIG.2, the rear wall 4 opposite to the front wall 3, the front wall 3, and a rear wall 4 and a pair of left and right gussets 5 and 5 which are connected to the side and folded inside the container body 1.
[0013]
The inner surfaces of both side edges 4a, 4a of the back wall 4 and the inner surfaces of one side edges 5a, 5a of both gussets 5, 5 are bonded by heat sealing with seal widths W3, W4. Seal portions 6 and 6 are formed at the locations. Further, both side edge portions 3a, 3a of the front wall 3 and the inner surfaces of the other side edge portions 5b, 5b of both gussets 5, 5 are separated from each other without being bonded. Further, the width W1 of the front wall 3 is smaller than the width W2 of the back wall 4 by more than the widths W3 and W4 of the seal portions 6 and 6, and has a relationship of W1 <W2− (W3 + W4). That is, the boundary portion 7 between the front wall 3 and the gusset 5 is located on the inner side of each seal portion 6 on both the left and right sides.
[0014]
Further, as shown in FIGS. 1 and 3, the container body 1 is continuously printed 10 from the front wall 3 to both gussets 5 and 5. More specifically, printing 10 is continuously performed from the seal portion 6 of one gusset 5 through the front wall 3 to the seal portion 6 of the other gusset 5.
[0015]
The sheet body is, for example, a gas barrier film such as a polyester film such as polyethylene terephthalate on which printing 10 has been applied, a polyamide film, and an aluminum foil, an ethylene vinyl alcohol copolymer film, or a film on which an inorganic substance is deposited as necessary. It is possible to employ a laminated film in which a layer of a heat-fusible resin such as polyethylene or polypropylene is formed on the inner surface of a base film in which is laminated. Moreover, arbitrary materials, such as another synthetic resin film, can also be used. In any case, it is sufficient that the inner surface side can be heat-sealed and a drink and other objects to be stored can be stored therein.
[0016]
On the other hand, the mouth member 2 includes an attachment portion 8 attached to the container body 1 and a spout portion on the upper end side of the attachment portion 8, and a removable lid 9 is screwed into the spout portion. Has been. And by removing the cover body 9, the to-be-contained object in the container main body 1 can be taken out from a spout part. The mouth member 2 is formed by molding from a synthetic resin that can be heat-sealed to the inner surface of the container body 1.
[0017]
Moreover, the container main body 1 comprised as mentioned above is manufactured as follows, for example. That is, a print 10 representing the main design of a product is applied in advance to a portion corresponding to the front wall 3 and both gussets 5 and 5 in one sheet body, and the ends of the sheet body (in FIG. 2) One side edge portion 5a of the gusset 5 and a portion corresponding to the side edge portion 4a of the back wall 4 are overlapped to form a cylindrical shape, and the cylindrical sheet body is folded to form a flat shape. At this time, since the printing 10 is performed on a single sheet body in advance, even if the front wall 3 and the gusset 5 are partitioned to form the printing 10 between the gussets 5 and 5 and the front wall 3. Continuity can be ensured automatically and reliably.
[0018]
Then, both side edges 4a and 4a of the back wall 4 and both gussets 5 and 5 are bonded by heat sealing with the upper and lower seal bars 20 and 20 as shown by the dashed lines in FIG. Since W1 is smaller than the width W2 of the back wall 4, only the adhesion between the back wall 4 and the gusset 5 can be reliably performed without the seal bars 20 and 20 coming into contact with the front wall 3.
[0019]
Furthermore, the bag-shaped container body 1 is created by bonding the inner surfaces of the sheet bodies at the lower end 1b by heat sealing, and then, when the upper end 1a of the container body 1 is sealed by heat sealing, At the same time, the attachment portion 8 of the mouth member 2 is inserted and attached to the inner surface side of the sheet body.
[0020]
When the container body 1 of the container with a mouth member having such a structure is filled with an object to be contained such as a beverage, the container body 1 swells as shown in FIG. Further, since the gussets 5 and 5 are formed on the sides, it is possible to ensure the independence when displayed.
[0021]
In the displayed state, both the gussets 5 and 5 are also provided with the front wall 3 and a series of prints 10 so that they are easily noticeable in appearance, and the back wall 4 is wider than the front wall 3 and the gusset 5 Since the printing 10 is applied up to the seal portion 6, the printing 10 of the gusset 5 can also be reliably recognized from the front.
[0022]
Moreover, since the printing 10 is continuously applied from the front wall 3 to the gusset 5, the printing 10 on the front wall 3 and the printing 10 on the gusset 5 appear as a series of designs, and the boundary between the front wall 3 and the gusset 5 The design is not interrupted at the part 7 and a unity design can be obtained. At the same time, since the design of the container main body 1 wraps around from the front wall 3 to the side gusset 5 side, a sense of depth and a three-dimensional feel can be obtained in the design.
[0023]
Furthermore, one continuous surface can be formed by the front wall 3 and the gusset 5 by not bonding the inner surfaces of the side edges 3a and 3a of the front wall 3 and the inner surfaces of both gussets 5 and 5. Accordingly, the print 10 of the gusset 5 is not easily blinded at the boundary portion 7, and the design from the front wall 3 to the gusset 5 is not visually interrupted, thereby further enhancing the continuity and unity in the design. And the three-dimensional effect is enhanced.
[0024]
Therefore, compared with the case where the print 10 is applied only to the front wall 3 or the case where the print 10 of the gusset 5 is separate and discontinuous from the print 10 of the front wall 3, the impact when displayed as a product. The degree of appeal to the buyer can be increased, and the appeal effect can be improved.
[0025]
In the present embodiment, the four horizontal lines are described as an example of the print 10, but the pattern of the print 10 is not limited to this, and printing of characters or the like may be used. It may be a combination of illustrations and scenery. Further, even if the print 10 does not reach the seal portion 6 of the gusset 5, it may be printed continuously up to the back wall 4, and the print 10 continues from the front wall 3 to the gusset 5 via the boundary portion 7. It only has to be applied. In addition, it is common for the back wall 4 to display the description of the objects to be contained, the method of use, etc., and notes.
[0026]
Further, it is within the scope of claim 1 even if both side edges 3a, 3a of the front wall 3 and both gussets 5, 5 are bonded to form an adhesive portion at the boundary portion 7. However, since the continuous printing 10 is divided into two sides according to the bonding portion, the printing portion 10 on the gusset 5 side tends to be a blind spot of the bonding portion when viewed from the front or obliquely forward, so that no bonding portion is provided as described above. It is preferable. Moreover, when the adhesion part is formed, it is preferable to narrow the width of the adhesion part.
[0027]
Moreover, in the said embodiment, although the container main body 1 is comprised from one sheet body, the front wall 3 and both gussets 5 and 5 are formed with one sheet body, and the back wall 4 is this sheet body. You may comprise from another sheet | seat body. Further, from the viewpoint of improving visibility, the print 10 is preferably continuously applied from the front wall 3 to the pair of left and right gussets 5 and 5 as in the above embodiment. If applied continuously, it is within the intended scope of the present invention. In such a case, the gusset 5 and the front wall 3 on the side where the printing 10 is continuously applied from the front wall 3 may be configured from at least one sheet body. In order to provide continuity of printing 10 between the front wall 3 and the gusset 5 in the case where the gusset 5 and the front wall 3 and separate sheet bodies are used, the side edge 3a of the front wall 3 and the gusset 5 This is because the bonding position with the side edge 5b must be strictly controlled. Even if the gusset 5 is provided only on one side, it is within the scope of the present invention.
[0028]
【The invention's effect】
As described above, the container with a mouth member of the present invention can obtain a design with a sense of unity from the front wall to the gusset by continuous printing from the front wall to the gusset, and can give the design a depth, A three-dimensional design can be obtained.
[0029]
Therefore, compared to the conventional flat design with printing only on the front wall, the impact when displayed as a product and the degree of appeal to the buyer can be increased, and the appeal effect can be improved. There is an effect that can be done.
[0030]
In addition, since the printing from the front wall to the gusset can be integrally performed on a single sheet body in advance, each sheet body can be used as in the case where the front wall and the gusset are composed of separate sheet bodies. It is no longer necessary to strictly control the alignment of the prints to ensure printing consistency at the boundary, and automatically and reliably ensure printing continuity between the gusset and the front wall even after the container is formed. It can be done.
[0031]
In particular, as described in claim 2, by not bonding the inner surface of the side edge of the front wall and the inner surface of the gusset, a single continuous surface can be formed by the front wall and the gusset, and the design from the front wall to the gusset is There is no visual discontinuity, the design continuity and sense of unity can be further enhanced, and the three-dimensional effect is enhanced.
