本発明は軟包装材料からなる比較的大型の、特に水などの液体充填用の自立袋に関するものであり、特に充填時の自立性と注出時の使い易さを考慮した自立袋に関する。
【0002】
【従来の技術】
従来、自立性と使い易さを考慮した比較的大型で液体充填用の自立袋としては、側部の形状に特徴を持たせ、例えば、無理にくびれを持たせることにより、自立袋の剛性を高め、自立袋の保形性を高めることが出来、くびれ部分を手で持つことにより自立袋を持ち易くしていた(例えば、特許文献1参照)。
【0003】
【特許文献1】
特願平5−116237号公報(図5)
【0004】
しかしながら、この種の自立袋は、どこを持たせるのか明確に表示されていないため扱いづらく、また、内容物が充填された胴部を持つことが多いため握力を調整する必要がある等の問題がある。
【0005】
【発明が解決しようとする課題】
本発明は、比較的大容量の自立袋に関する以上のような問題点を解決するためになされたもので、比較的シンプルな形状にして液状の内容物を充填した際の自立性と、内容物を注出する際の使いやすさを考慮した自立袋を提供することを課題とする。
【0006】
【課題を解決するための手段】
本発明の請求項1の発明は、二つ折りされた底テープと表裏二枚の本体フィルムの両端縁を側部シールし、下部端縁を船底形状に底部シールしてなる自立袋において、該自立袋の天部の開口部の未シール部分の幅が、自立袋の最大幅の40〜80%になるように、天部の上縁から下方の側部シールに向けて、左右対称に徐徐に未シール幅を広くした傾斜部シールを形成させ、該傾斜部シールと側部シールの交差部分が、自立袋の高さの半分より下方に位置するようにしたことを特徴とする、自立袋である。
【0007】
このように請求項1記載の発明によれば、自立袋の天部の開口部の未シール部部の幅が、自立袋の最大幅に対して40〜80%になるように、天部の上縁から下方の側部シールに向けて、左右対称に徐徐に未シール幅を広くした傾斜部シールを形成させ、該傾斜部シールと側部シールの交差部分が、自立袋の高さの半分より下方に位置するようにしたので、内容物を充填した自立袋は、内容物の重量の影響を受けて傾斜部シールした部分が片側に入り込み自立性が安定する。
【0008】
また、請求項2の発明は、請求項1の発明において、前記傾斜部シールの一方の角隅寄りを、上方の天部から下方の側部シールとの交差部分に向けて、傾斜部シールのシール幅が徐徐に幅狭になるように切断したことを特徴とする、自立袋である。
【0009】
このように請求項2記載の発明によれば、傾斜部シールの一方の角隅寄りを、上方の天部から下方の側部シールとの交差部分に向けて、傾斜部シールのシール幅が徐徐に幅狭になるように切断したので、傾斜部シールの狭幅部分にあたるところに入り込み部が位置して、上部のシールの幅広い部分に入り込むことがない。
【0010】
また、請求項3の発明は、請求項1の発明において、前記傾斜部シールの両方の角隅寄りを、上方の天部から下方の側部シールとの交差部分に向けて、傾斜部シールのシール幅が徐徐に幅狭になるように左右対称に切断したことを特徴とする、自立袋である。
【0011】
このように請求項3記載の発明によれば、傾斜部シールの両方の角隅寄りを、上方の天部から下方の側部シールとの交差部分に向けて、傾斜部シールのシール幅が徐徐に幅狭になるように左右対称に切断したので、左右対称の入り込みをした自立袋になり、見た目がバランスが良く見える。
【0012】
また、請求項4の発明は、請求項1〜3のいずれか1項に記載の発明において、前記傾斜部シールの片方若しくは両方の側部シールとの交差部分近傍に切り欠きが穿設されていることを特徴とする、自立袋である。
【0013】

【0018】
【発明の実施の形態】
本発明の自立袋を一実施形態に基づいて以下に詳細に説明する。
本発明の自立袋(10)は、例えば図1、図2、図3、図4に示すように、二つ折りされた底テープと表裏二枚の本体フィルムの両端縁を側部シール(11、11)し、下部端縁を船底形状に底部シール(12)してなる自立袋において、自立袋の天部(13)の開口部の未シール部分の幅(E)が、自立袋の最大幅(F)の40〜80%になるように、天部の上縁から下方の側部シール(11)に向けて、左右対称に徐徐に未シール幅を広くした傾斜部シール(14、14)を形成させ、該傾斜部シールと側部シールの交差部分(k)が、自立袋の高さの半分より下方に位置するようにしたものである。
【0019】
E/Fを0.4〜0.8、より好ましくは0.4〜0.6に設定することにより、水等の液体を充填して天部を密封シールした自立袋を、例えば、底面に置いた際、自然にくびれが発生して安定して底面に置くことができ、自立性が向上する。
【0020】
E/Fが0.4未満であると、大きなくびれが発生するがこのくびれのバランスが悪くなりやすく、上部が傾き易いという不都合が発生し、また、E/Fが0.8を越えると、傾斜部シールが略垂直になり、傾斜部でなく側部シール(11)にくびれが発生してしまい底部シール(12)との交点に過負荷がかかることになり、自立袋の落下衝撃強度の支えになる交点への過負荷は品質上好ましくないというう不都合が発生する。
【0021】
そして、傾斜部シール(14、14)の一方又は両方の角隅寄りを、上方の天部上縁から下方の側部シール(11、11)との交差部分(k、k)に向けて、傾斜部シールのシール幅を徐徐に狭幅になるように切断(15)しても良い。
【0022】
傾斜部シール(14、14)の一方又は両方の角隅寄りを、図4に示すように、シール幅が徐徐に狭くなるように切断することにより、傾斜部シールの狭幅部分に入り込み部が位置するので、傾斜部シールの広幅部分に入り込むことがない。
【0023】
また、傾斜部シール(14、14)の片方若しくは両方の側部シール(11、11)との交差部分(k、k)の近傍に切り欠き(16、16)を穿設しておくと、自立袋に液体等の内容物を充填して天部をヒートシール等して密封して自立させた際、上部の傾斜部シールが内側に巻き込まれる度合いが少なくて済む(図5参照)。
切り欠き(16)の形状は、半円形、丸形などが好ましい。
【0024】
さらに、角隅を切断していない方の傾斜部シールの上部角隅部分に、取っ手(17)を付与しておくことにより、液体の内容物を充填した後、自立袋の上部は略円柱状になるため、自立袋が持ち易くなる(図2、図4、図5参照)。
取っ手(17)は、孔をあけても良いし、別体を取り付けても良い。
【0025】
天部(13)に口栓(18)を取り付けることにより、内容物を注出する際、効率良く、内容物を注ぎ出すことができる。口栓(18)は天部ではなく、傾斜部シール(14)の部分に取り付けることもできる。
【0026】
自立袋(10)を作製する際に使用する底テープや本体フィルムの材質構成は、特に限定されるものではなく、例えば、ポリエチレンテレフタレートフィルム/ナイロンフィルム/直鎖状低密度ポリエチレンフィルムの三層から構成される複合フィルムなど、一般的に公知の複合フィルムを使用すれば良い。
【0027】
【実施例】
以下実施例により本発明の自立袋をさらに詳細に説明する。
〈実施例1〉
先ず、本体フィルムおよび底テープとして、ポリエチレンテレフタレートフィルム(厚さ12μm)/ナイロンフィルム(厚さ15μm)/直鎖状低密度ポリエチレンフィルム(厚さ150μm)の三層構成からなる複合フィルムを準備した。
【0028】
このような層構成からなる本体フィルムと底テープを用いて、高さ(H);270mm、幅(F);220mm、自立袋の底辺から傾斜部シールが側部シールと交差する点(k)までの長さ;110mm、天部の傾斜部シールの切断部分の長さ(B);50mm、切断された傾斜部シールの側部シールと交差する点の幅(C);8mm、切断された傾斜部シールの天部近傍での幅(D);10mm、からなる図2、図4に示すような形状の自立袋を、一般的に公知の自立袋用の製袋機と断裁機を使用して作製し、実施例1の自立袋とした。このときのE/Fは55%であった。
【0029】
なお、切断してない角隅部分には長孔を穿設して取っ手(17)とし、また、天部にはプラスチック製の口栓(18)を取り付けた。
【0030】
この実施例1の自立袋に2リットルの水を充填したところ、傾斜部シール(14)が水の重量の影響を受けて図5に示すように入り込み、くびれが発生して自立性が安定することが判った。
そして切り欠き(16)が設けられているので、傾斜部シール(14)が内側に余り巻き込まれず、形よく自立している。
また、取っ手(17)や口栓(18)が取り付けられており、持ち易く、内容物を外に安定して注ぎ出すことができる。
【0031】
【発明の効果】
本発明の自立袋は、以上のような形状から構成されているので、比較的シンプルで、液体を充填した際に自立性が安定し、内容物を注出する際にも使い易いという効果がある。

The present invention relates to a relatively large self-supporting bag made of a soft packaging material, particularly for filling liquids such as water, and more particularly to a self-supporting bag considering self-supporting properties during filling and ease of use during dispensing.
[0002]
[Prior art]
Conventionally, as a relatively large and self-supporting bag for liquid filling considering self-supporting and ease of use, the shape of the side part is characterized, for example, by constricting the constriction, the rigidity of the self-supporting bag is increased. The shape of the self-supporting bag can be increased, and the self-supporting bag can be easily held by holding the constricted portion by hand (see, for example, Patent Document 1).
[0003]
[Patent Document 1]
Japanese Patent Application No. 5-116237 (FIG. 5)
[0004]
However, this kind of self-supporting bag is difficult to handle because it is not clearly displayed where it is to be held, and it is often necessary to adjust the grip strength because it has a body part filled with contents. There is.
[0005]
[Problems to be solved by the invention]
The present invention was made to solve the above-mentioned problems related to relatively large-capacity self-supporting bags. The self-supporting property when the liquid contents are filled in a relatively simple shape and the contents are provided. It is an object to provide a self-supporting bag in consideration of ease of use when pouring out.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a self-supporting bag in which both end edges of a bottom folded tape and two main and rear body films are side-sealed and a lower edge is bottom-sealed in a bottom shape. Gradually gradually and symmetrically from the upper edge of the top to the lower side seal so that the width of the unsealed part of the opening of the top of the bag is 40 to 80% of the maximum width of the free-standing bag A self-standing bag characterized in that an inclined portion seal having a wide unsealed width is formed, and an intersection portion of the inclined portion seal and the side seal is located below half of the height of the self-standing bag. is there.
[0007]
Thus, according to invention of Claim 1, the width | variety of an unsealed part of the opening part of the ceiling part of a self-supporting bag becomes 40 to 80% with respect to the maximum width of a self-supporting bag, An inclined part seal having an unsealed width gradually increased symmetrically from the upper edge toward the lower side seal is formed, and the intersection of the inclined part seal and the side seal is half the height of the self-supporting bag. Since the self-supporting bag filled with the contents is affected by the weight of the contents, the sealed portion of the inclined portion enters one side and the self-supporting stability is stabilized.
[0008]
According to a second aspect of the present invention, in the first aspect of the present invention, the inclined portion seal of the inclined portion seal is directed toward an intersecting portion of the inclined portion seal from the upper top portion to the lower side seal. The self-standing bag is characterized by being cut so that the seal width gradually becomes narrower.
[0009]
Thus, according to the second aspect of the present invention, the seal width of the inclined portion seal gradually increases from one corner of the inclined portion seal toward the intersection with the lower side seal from the upper ceiling. Therefore, the entry portion is located at the narrow portion of the inclined portion seal and does not enter the wide portion of the upper seal.
[0010]
According to a third aspect of the present invention, in the first aspect of the present invention, the inclined portion seals of the inclined portion seals are directed toward the intersections between the upper ceiling and the lower side seals. The self-standing bag is characterized by being cut symmetrically so that the seal width gradually becomes narrower.
[0011]
Thus, according to the third aspect of the present invention, the seal width of the inclined portion seal is gradually increased toward both the corners of the inclined portion seal toward the intersection with the lower side seal from the upper ceiling. Since it is cut symmetrically so that it becomes narrow, it becomes a self-supporting bag with a symmetrical entry, and the appearance looks good.
[0012]
According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, a notch is formed in the vicinity of an intersecting portion with one or both side seals of the inclined portion seal. It is a self-supporting bag characterized by being.
[0013]
Thus, according to the fourth aspect of the present invention, since the notch is formed in the vicinity of the intersecting portion with one or both side seals of the inclined portion seal, the upper inclined portion seal is wound inside. To prevent you from going.
[0014]
The invention of claim 5 is characterized in that, in the invention of claim 1 or 2, a handle is given to the upper corner portion of the inclined portion seal that is not cut at the corner. It is a free-standing bag.
[0015]
Thus, according to the fifth aspect of the present invention, the upper part of the self-supporting bag becomes a substantially columnar shape after filling the contents. Therefore, if the handle is provided, the self-supporting bag can be easily grasped.
[0016]
The invention according to claim 6 is the self-supporting bag according to any one of claims 1 to 5, wherein the top portion is provided with a plug.
[0017]
Thus, according to the sixth aspect of the present invention, it is convenient to pour the contents from the self-supporting bag by providing a stopper on the top.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
The self-supporting bag of the present invention will be described in detail below based on one embodiment.
The self-supporting bag (10) of the present invention has, as shown in FIGS. 1, 2, 3, and 4, for example, side seals (11, 11) In the self-supporting bag having the bottom edge sealed to the bottom of the ship (12), the width (E) of the unsealed portion of the opening of the top (13) of the self-supporting bag is the maximum width of the self-supporting bag. Inclined part seals (14, 14) in which the unsealed width is gradually increased symmetrically from the upper edge of the top to the lower side seal (11) so as to be 40 to 80% of (F). The crossing portion (k) of the inclined portion seal and the side portion seal is positioned below half of the height of the self-supporting bag.
[0019]
By setting the E / F to 0.4 to 0.8, more preferably 0.4 to 0.6, a self-supporting bag filled with a liquid such as water and hermetically sealed to the top is formed on the bottom surface, for example. When placed, the neck is naturally constricted and can be stably placed on the bottom surface, improving the independence.
[0020]
When the E / F is less than 0.4, a large constriction occurs, but the balance of the constriction tends to be poor, and the inconvenience that the upper part tends to tilt occurs. When the E / F exceeds 0.8, The inclined portion seal becomes substantially vertical, and the side seal (11), not the inclined portion, is constricted, and an overload is applied to the intersection with the bottom seal (12). An inconvenience that an overload at a supporting intersection is undesirable in terms of quality occurs.
[0021]
Then, one or both corners of the inclined portion seal (14, 14) are directed from the upper top edge of the upper portion toward the intersection (k, k) with the lower side seal (11, 11). You may cut | disconnect (15) so that the seal width of an inclination part seal may become narrow gradually.
[0022]
As shown in FIG. 4, as shown in FIG. 4, one or both corners of the inclined portion seal (14, 14) are cut so that the seal width gradually becomes narrower, so that the narrow portion of the inclined portion seal enters the narrow portion. Since it is located, it does not enter the wide part of the inclined portion seal.
[0023]
Further, when the notch (16, 16) is formed in the vicinity of the intersection (k, k) with one or both side seals (11, 11) of the inclined portion seal (14, 14), When the self-supporting bag is filled with contents such as liquid and the top portion is sealed by heat sealing or the like to be self-supporting, the upper inclined portion seal is less likely to be caught inside (see FIG. 5).
The shape of the notch (16) is preferably a semicircle, a round shape, or the like.
[0024]
Furthermore, the upper portion of the self-standing bag is substantially cylindrical after filling the liquid content by providing a handle (17) to the upper corner portion of the inclined portion seal that is not cut. Therefore, it becomes easy to hold a self-supporting bag (see FIGS. 2, 4, and 5).
The handle (17) may be perforated or a separate body may be attached.
[0025]
By attaching the plug (18) to the top (13), the contents can be efficiently poured out when the contents are poured out. The spigot (18) can be attached not to the top portion but to the portion of the inclined portion seal (14).
[0026]
The material composition of the bottom tape and the main body film used when producing the self-supporting bag (10) is not particularly limited. For example, from three layers of polyethylene terephthalate film / nylon film / linear low density polyethylene film A generally known composite film such as a composed composite film may be used.
[0027]

[0028]
Using the main body film and the bottom tape having such a layer structure, the height (H): 270 mm, the width (F): 220 mm, the point where the inclined portion seal intersects the side seal from the bottom of the free-standing bag (k) 110 mm, the length of the cut portion of the top slope seal (B); 50 mm, the width of the cut intersection of the side seal of the slope seal (C); 8 mm, cut A self-standing bag having a shape as shown in FIG. 2 and FIG. 4 having a width (D) near the top of the inclined portion seal of 10 mm is generally used using a bag-making machine and a cutting machine for a known self-standing bag. Thus, a self-supporting bag of Example 1 was obtained. The E / F at this time was 55%.
[0029]
In addition, a long hole was drilled in a corner portion that was not cut to form a handle (17), and a plastic plug (18) was attached to the top.
[0030]
When the self-supporting bag of Example 1 was filled with 2 liters of water, the inclined portion seal (14) entered under the influence of the weight of the water as shown in FIG. I found out.
And since the notch (16) is provided, the inclination part seal | sticker (14) is not entangled too much inside and is standing in shape well.
Moreover, the handle (17) and the stopper (18) are attached, it is easy to hold and the content can be poured out stably.
[0031]
【The invention's effect】
Since the self-supporting bag of the present invention is composed of the shape as described above, it is relatively simple, has the effect that the self-supporting property is stable when filled with a liquid, and is easy to use even when the contents are poured out. is there.
