Description

本発明は、積層フィルムの周囲をシールしてなる自立可能なパウチ本体と、該パウチ本体に接合される、熱可塑性樹脂の略円筒状部材を有する充填口部材と、からなる、パウチ容器に関し、特に、胴部保型性および自立安定性を向上したパウチ容器に関する。 The present invention relates to a pouch container comprising a self-standing pouch main body formed by sealing the periphery of a laminated film, and a filling port member having a substantially cylindrical member of a thermoplastic resin joined to the pouch main body. In particular, the present invention relates to a pouch container having improved body shape retaining property and self-supporting stability.

従来、主に店頭で販売されるドレッシングや各種味付け用のタレ類など、図１６（ａ）に示すように、ガラス瓶Ｇの容器などのボトル形状の容器を用いることが多い。このようなガラス瓶容器Ｇは、容器Ｇの耐久性や自立時の安定性に優れるものの、ガラス瓶Ｇは重量が重く、さらには落とすと割れてしまう危険性がある。そこで、近年、図１６（ｂ）に示すように、プラスチック成型品からなるブローボトルＢに注出口を設けた容器を用いる場合がある。 Conventionally, as shown in FIG. 16 (a), a bottle-shaped container such as a glass bottle G container is often used, such as dressing mainly sold at stores and sauces for various seasonings. Although such a glass bottle container G is excellent in the durability of the container G and the stability at the time of self-supporting, the glass bottle G is heavy and there is a risk of cracking if dropped. Therefore, in recent years, as shown in FIG. 16B, a container provided with a spout in a blow bottle B made of a plastic molded product may be used.

他方、シャンプーやリンス、液体洗剤などは、ボトル容器から袋状のパウチへと移行が進んでおり、このようなパウチは、減容性および廃棄性に優れており、環境に配慮した容器形態となっている。 On the other hand, shampoos, rinses, liquid detergents, etc. are moving from bottle containers to bag-shaped pouches, and such pouches are excellent in volume reduction and disposal, and are environmentally friendly container forms. It has become.

しかしながら、このようなパウチでは、内容物の量によってはパウチの自立性が不安定という欠点があり、パウチをそのままの状態で直接用いることが困難である。よって、パウチの内容物を、ブローボトル容器Ｂへと移し替える等の手間を要し、ドレッシングや焼肉のタレなどの食品類を内容物として扱うことが困難であった。このため、液体の食品類は、ブローボトルＢやガラス瓶Ｇなどの容器形態で販売されることが多く、パウチへの移行が進まずにいる。 However, such a pouch has a disadvantage that the self-supporting property of the pouch is unstable depending on the amount of contents, and it is difficult to directly use the pouch as it is. Therefore, it takes time and effort to transfer the contents of the pouch to the blow bottle container B, and it has been difficult to handle foods such as dressings and grilled meat sauce as contents. For this reason, liquid food products are often sold in the form of containers such as blow bottles B and glass bottles G, and the transition to pouches has not progressed.

また、図１７に示すように、主に、清涼飲料などを内容物とした、前記パウチＰに口径の小さいスパウトＳＰ（注出口）を取り付けたスパウト付きパウチＰがあるが、筒状部材からなるスパウトＳＰが、内容物の充填口と注出口とを兼ね備えるため、口径の小さいスパウトＳＰの場合には、内容物の充填スピードが遅くなるという問題がある。 Moreover, as shown in FIG. 17, although there exists a pouch P with a spout which mainly attached the soft pouch etc. and attached the spout SP (pouring spout) with a small diameter to the said pouch P, it consists of a cylindrical member. Since the spout SP has both a filling port and a spout for the content, there is a problem that the filling speed of the content is slow in the case of a spout SP having a small diameter.

また、このようなスパウト付きパウチＳでは、スパウトＳＰから内容物を吸い出し、若しくは内容物を絞り出すことにより使用するが、パウチＰ内部に残存する内容物を余すことなく注出することや、パウチＰを傾けても、内容物を取り出し切ることが困難という欠点がある。さらには、内容物の減少に伴い、パウチＰがしぼみ、パウチＰの自立が不安定となる欠点も有する。そして、スパウトＳの口径を大きくして注出性の向上を図った場合には、スパウトＳＰの重量が増大してしまうこととなり、同時に自立性を向上させることは不可能である。 Moreover, in such a pouch S with a spout, it is used by sucking out the contents from the spout SP or squeezing out the contents. However, it is possible to pour out the remaining contents inside the pouch P without leaving the pouch P. Even if tilted, there is a drawback that it is difficult to take out the contents. In addition, as the contents are reduced, the pouch P is squeezed, and the pouch P is not self-supporting. When the diameter of the spout S is increased to improve the pouring property, the weight of the spout SP increases, and at the same time, it is impossible to improve the self-supporting property.

特に、この種のスパウトＳＰとパウチ本体Ｐとの接合部分の、前記スパウトＳＰ断面外周は、同心円状にスパウト上部、下部とも同一寸法を有しているが、パウチＰの開口内周寸法と前記スパウトＳＰ断面外周寸法には、大きな寸法差が存在している。
すなわち、パウチ本体１における上部のフィルムは、スパウト接合前において、下部のフィルムと同形状を有するが、スパウトを接合することでパウチ本体の下部のフィルムと上部のフィルムとに形状の違いがでることとなる。 In particular, the spout SP cross-section outer periphery of the joint portion between this type of spout SP and the pouch body P has the same dimensions in the upper and lower portions of the spout concentrically. There is a large dimensional difference in the outer diameter of the spout SP cross section.
That is, the upper film in the pouch main body 1 has the same shape as the lower film before spout bonding, but the difference in shape between the lower film and the upper film of the pouch main body can be made by bonding the spout. It becomes.

よって、パウチＰにスパウトＳＰを取り付けた上記スパウト付きパウチＳでは、パウチ本体に内容物を充填した際に、パウチＰの底部が膨らむとともに、スパウトＳＰが接合されたパウチの上部断面形状と底部の断面形状とに差異が生じるため、パウチの胴部にシワが生じ、見栄えが良くないという問題があった。また、パウチの胴部が内容物によりパウチ本体の膨らみを維持しており、内容物の減少に伴い、パウチのシワ部分を起点にパウチ本体が折れ曲ってしまうという問題があった。 Therefore, in the pouch S with a spout in which the spout SP is attached to the pouch P, when the pouch body is filled with the contents, the bottom portion of the pouch P swells and the top cross-sectional shape of the pouch to which the spout SP is joined and Since there is a difference in cross-sectional shape, there is a problem that wrinkles are generated in the body portion of the pouch and the appearance is not good. In addition, there is a problem that the body of the pouch maintains the swelling of the pouch body due to the contents, and the pouch body is bent starting from the wrinkled portion of the pouch as the contents decrease.

他方、例えば、特許文献１に示すように、筒状に形成した注ぎ口本体と、注ぎ口本体上面を覆うように設けた蓋体と、袋状容器の開口縁を前記注ぎ口本体の円筒部に密着させるための締付手段とにより構成される、袋状容器用栓が開示されており、注ぎ口本体（３）の円筒部（４）が、袋状容器（１）と密着しやすいように、後側下部ほど幅広のテーパー状に成型された袋状容器用の栓が記載されている。 On the other hand, for example, as shown in Patent Document 1, a pour spout body formed in a cylindrical shape, a lid provided so as to cover the top surface of the spout main body, and an opening edge of the bag-like container are formed in a cylindrical portion of the spout main body. A stopper for a bag-like container is disclosed, which is constituted by a fastening means for tightly adhering to the bag, so that the cylindrical portion (4) of the spout body (3) can be in close contact with the bag-like container (1). In addition, there is described a bag-shaped container stopper formed into a taper shape that is wider toward the lower rear side.

しかしながら、このような容器は、使用者が袋入り製品に取り付けて用いる、着脱自在な注ぎ口であり、前記円筒部（４）と袋状容器との密着を袋口部材による締め付けによってのみ行なう構成である。 However, such a container is a detachable spout that is used by a user attached to a product in a bag, and the cylindrical portion (4) and the bag-like container are closely attached only by fastening with a bag mouth member. It is.

よって、使用者の利便を目的に予め注ぎ口を取り付けて流通させる容器としては、同密着部からの液漏れ等の恐れがあり、さらには、このような簡易な接合では、注ぎ口本体（３）を把持して容器を取り扱うと、接合部から袋が脱落してしまう等の問題があるため、同公報でも取り扱いを確実にする例として、別途、袋状容器１に装着する略Ｕ字状の合成樹脂製ケース（２３）を挙げている。 Therefore, as a container to which a spout is attached and distributed in advance for the convenience of the user, there is a risk of liquid leakage from the close contact portion. Further, in such simple joining, the spout main body (3 When the container is handled while holding the container), there is a problem that the bag falls off from the joint portion. Therefore, as an example for ensuring the handling in the same publication, a substantially U-shape that is separately attached to the bag-like container 1 is used. The synthetic resin case (23) is mentioned.

以下に、本発明の容器Ａを構成する、充填口部材２、パウチ本体１について、それぞれ説明する。 Below, the filling port member 2 and the pouch main body 1 which comprise the container A of this invention are each demonstrated.

まず、前記充填口部材２は、詳しくは、図２（ａ）に示すように、熱可塑性樹脂からなる、下部の接合部２２と、上部に設けられた２段のフランジ部２３、２４（上段フランジ部２４、下段フランジ部２３）とを有し、充填口部材２の中央部には、開口部２１を有する略円筒状の充填口が貫設されたものである。そして、前記上段フランジ２４は、後述する、注出口部材３を充填口部材２へと嵌合するための嵌合フランジ２４であり、前記下段フランジ部２３は、後述する、パウチ本体１の開口端と接する位置まで充填口部材２を挿入するための位置決めフランジ２３である。 First, as shown in FIG. 2 (a), the filling port member 2 includes a lower joint portion 22 made of a thermoplastic resin, and two flange portions 23 and 24 (upper steps) provided on the upper portion. A flange portion 24 and a lower flange portion 23), and a substantially cylindrical filling port having an opening 21 is provided through the center of the filling port member 2. And the said upper stage flange 24 is the fitting flange 24 for fitting the spout member 3 to the filling port member 2 mentioned later, and the said lower stage flange part 23 is the opening end of the pouch main body 1 mentioned later. It is a positioning flange 23 for inserting the filling port member 2 to a position in contact with.

特に、前記接合部２２は、図２（ｂ）（ｃ）に示すように、接合部２２の正面と裏面との円弧部分の半径Ｒ２が、充填口部材２の充填口の開口部２１の半径Ｒ１と、同一若しくは小さな半径Ｒ２を有しており（Ｒ１≧Ｒ２）、後述する、前記充填口部材２をパウチ本体１へと接合することにより、パウチ本体１の側面形状が略直円筒形状を形成して、パウチ容器Ａの胴部保型性および自立安定性を向上することが可能である。 In particular, as shown in FIGS. 2B and 2C, the joint 22 has a radius R2 of the arc portion between the front surface and the back surface of the joint 22 and the radius of the opening 21 of the filling port of the filling port member 2. R1 has the same or small radius R2 (R1 ≧ R2). By joining the filling port member 2 described later to the pouch main body 1, the side surface of the pouch main body 1 has a substantially right cylindrical shape. It is possible to improve the trunk shape retaining property and the self-supporting stability of the pouch container A by forming.

次に、前記パウチ本体１は、図３（ａ）に示すように、積層フィルムの左右シール１２および底部シール１３が施されてなる上方に開口１１を有する筒状のパウチ本体１であって、図３（ｂ）に示すように、パウチ本体１の上部分に形成された開口１１へと、前記充填口部材２の下段フランジ部２３と、パウチ本体１の開口端１１とが接する位置まで、前記接合部２２を挿入した後、図４（ａ）に示すように、パウチ本体１の上部シール１５（接合部分１５）を形成することにより、パウチ本体１の上部シール１５が、前記充填口部材２の接合部２２に沿って形成されて、本発明のパウチ容器Ａを形成するものである。 Next, as shown in FIG. 3 (a), the pouch body 1 is a cylindrical pouch body 1 having an opening 11 above the left and right seals 12 and a bottom seal 13 of a laminated film, As shown in FIG. 3 (b), the opening 11 formed in the upper part of the pouch body 1 reaches a position where the lower flange portion 23 of the filling port member 2 and the opening end 11 of the pouch body 1 are in contact with each other. After the joining portion 22 is inserted, as shown in FIG. 4A, the upper seal 15 (joining portion 15) of the pouch body 1 is formed so that the upper seal 15 of the pouch body 1 becomes the filling port member. The pouch container A of the present invention is formed along the two joint portions 22.

そして、充填口部材２の大きな開口２１から、内容物をパウチ本体１へと充填することが可能であり、内容物の充填に伴い、図４（ｂ）に示すように、パウチ本体１の底部１４が膨らみ、パウチ本体１の自立部分１４を形成するものである。 Then, the contents can be filled into the pouch body 1 from the large opening 21 of the filling port member 2, and as shown in FIG. 4 (b), the bottom of the pouch body 1 is filled with the filling of the contents. 14 swells to form a self-supporting portion 14 of the pouch body 1.

このとき、接合部２２の正面及び裏面の円弧部分の半径Ｒ２が、充填口の開口部２１の半径Ｒ１以下である場合、パウチ本体１が直円筒形状をなすため、パウチの正面および裏面のフィルムが、前記充填口部材２とパウチ１の底部１４とをつなぐ柱を形成して、パウチ本体１が安定して自立することが可能であるとともに優れた胴部保型性を奏することが可能である。 At this time, when the radius R2 of the arc portion of the front surface and the back surface of the joint portion 22 is equal to or less than the radius R1 of the opening portion 21 of the filling port, the pouch body 1 has a right cylindrical shape. However, it is possible to form a column connecting the filling port member 2 and the bottom 14 of the pouch 1 so that the pouch body 1 can stably stand on its own and exhibit excellent shape retention. is there.

すなわち、図５（ａ）に示すように、パウチ本体１の側面視での表裏フィルム形状が、接合部２２の円弧部分の半径Ｒ２から底部１４にかけて、直線状のフィルム面を形成しており、図５（ｂ）に示すように、接合部２２の正面及び裏面間の円弧部分の半径Ｒ２間の側面幅Ｗと、パウチ本体１の底部１４の、正面及び裏面間の側面幅ｗとが、略等しい長さとなる（Ｗ＝ｗ）。 That is, as shown in FIG. 5A, the front and back film shape in the side view of the pouch body 1 forms a linear film surface from the radius R2 of the arc portion of the joint portion 22 to the bottom portion 14, As shown in FIG. 5 (b), the side surface width W between the radius R2 of the arc portion between the front surface and the back surface of the joint portion 22 and the side surface width w between the front surface and the back surface of the bottom portion 14 of the pouch body 1 are as follows. The lengths are approximately equal (W = w).

これにより、図５（ｂ）に示すように、底部分１４の断面形状が、充填口部材２の筒状部材の断面形状と略等しい形状となり、パウチ本体１が略直円筒形状を形成することが可能である。よって、パウチ本体１の正面および裏面のフィルムが、前記充填口部材２とパウチ本体１の底部１４とをつなぐ柱を形成して、パウチ本体１にシワが生じることや折れ曲ってしまうことを防ぎ、優れた胴部保型性および自立安定性を奏することが可能である。 Thereby, as shown in FIG.5 (b), the cross-sectional shape of the bottom part 14 becomes a shape substantially equal to the cross-sectional shape of the cylindrical member of the filling port member 2, and the pouch main body 1 forms a substantially right cylindrical shape. Is possible. Therefore, the front and back films of the pouch main body 1 form a column connecting the filling port member 2 and the bottom 14 of the pouch main body 1 to prevent the pouch main body 1 from being wrinkled or bent. It is possible to exhibit excellent body shape retention and self-supporting stability.

これに対して、例えば、接合部２２の正面及び裏面間の前記円弧部分の半径Ｒ２間の側面幅Wと、パウチ本体１の底部１４の正面及び裏面間の前記側面幅Wとが等しく（Ｗ＝ｗ）、接合部２２の正面及び裏面の前記円弧部分の半径Ｒ２が、前記充填口の開口部２１の半径Ｒ１より大きい場合（Ｒ２＞Ｒ１）、表裏接合部１５の前記円弧に対する接線延長上の交点が遠いため、舟形部正面から見た幅が広くなり、材料、重量の点で好ましくない。さらには、パウチ本体１の自立性に悪影響を与えてしまうという問題がある。 On the other hand, for example, the side surface width W between the radii R2 of the arc portion between the front surface and the back surface of the joint portion 22 is equal to the side surface width W between the front surface and the back surface of the bottom portion 14 of the pouch body 1 (W = W) When the radius R2 of the arc portion of the front surface and the back surface of the joint portion 22 is larger than the radius R1 of the opening portion 21 of the filling port (R2> R1), the front and back joint portion 15 is tangentially extended with respect to the arc. Since the intersection of is far, the width seen from the front of the boat-shaped portion is widened, which is not preferable in terms of material and weight. Furthermore, there is a problem in that the independence of the pouch body 1 is adversely affected.

また、前記接合部２２の正面及び裏面間の円弧部分の半径Ｒ２間の側面幅Wと、パウチ本体１の底部１４の、正面及び裏面間の側面幅ｗとが異なり（Ｗ≠ｗ）、前記半径Ｒ２が、前記半径Ｒ１より大きい場合（Ｒ２＞Ｒ１）、舟形部は薄くなり、パウチ本体の上下部分の長さ（厚み）が異なるため、パウチ本体１が折れやすく、また、外観にシワが形成されるため、内容物の減少時において、パウチ本体１の自立性が低下してしまうという問題がある。 Further, the side width W between the radii R2 of the arc portion between the front surface and the back surface of the joint portion 22 is different from the side surface width w between the front surface and the back surface of the bottom portion 14 of the pouch body 1 (W ≠ w). When the radius R2 is larger than the radius R1 (R2> R1), the boat-shaped portion is thin and the length (thickness) of the upper and lower portions of the pouch body is different, so that the pouch body 1 is easily broken and the appearance is wrinkled. As a result, there is a problem that the self-supporting property of the pouch body 1 is reduced when the contents are reduced.

よって、本発明のパウチ容器Ａは、接合部２２の正面と裏面との円弧部分の半径Ｒ２が、充填口の開口部２１の半径Ｒ１と、同一若しくは小さな半径Ｒ２を有し（Ｒ１≧Ｒ２）、接合部２２の正面及び裏面間の円弧部分の半径Ｒ２間の側面幅Wと、パウチ本体１の底部１４の、正面及び裏面間の側面幅ｗとが、略等しい長さとなる（Ｗ＝ｗ）前記充填口部材２を、パウチ本体１へと接合することにより、パウチ本体１の底部１４の断面形状が、充填口部材２の接合部２２の断面形状と略同様の形状となり、パウチ本体１が略直円筒形状を形成することとなる。これにより、パウチの正面および裏面のフィルムが、前記充填口部材２とパウチの底部１４とをつなぐ柱を形成して、パウチ本体１の側面形状が直線形状を維持するため、パウチ本体１にシワが生じることや折れ曲ってしまうことを防ぎ、優れた胴部保型性および自立安定性を奏することが可能である。パウチ容器Ａの胴部保型性および自立安定性を向上することが可能である。 Therefore, in the pouch container A of the present invention, the radius R2 of the arc portion between the front surface and the back surface of the joint portion 22 has the same or smaller radius R2 as the radius R1 of the opening portion 21 of the filling port (R1 ≧ R2). The side surface width W between the radii R2 of the arc portion between the front surface and the back surface of the joint portion 22 and the side surface width w between the front surface and the back surface of the bottom portion 14 of the pouch body 1 are substantially equal (W = w). ) By joining the filling port member 2 to the pouch body 1, the cross-sectional shape of the bottom portion 14 of the pouch body 1 becomes substantially the same as the cross-sectional shape of the joint portion 22 of the filling port member 2. Will form a substantially cylindrical shape. Accordingly, the film on the front and back surfaces of the pouch forms a column connecting the filling port member 2 and the bottom 14 of the pouch, and the side surface shape of the pouch main body 1 maintains a linear shape. It is possible to prevent occurrence of bending and bending, and to exhibit excellent body shape retention and self-supporting stability. It is possible to improve the body shape retaining property and the self-supporting stability of the pouch container A.

また、本発明のパウチ容器Ａは、図６に示すように、前記充填口部材２の上段フランジ部２４に初期開封シールＰを形成してもよく、パウチ容器Ａの内容物を密封、保存することが可能であり、酸素ガス、炭酸ガス、水蒸気等の透過を遮断する耐透過性を向上して、内容物の品質保持性を向上したパウチ容器Ａを提供することが可能である。特に、内容物を収容するパウチ本体１は、柔軟性があるため、商品搬送時においても、ガラス瓶やブローボトルのように破損や傷を生じることなく、商品を扱いやすいという効果がある。 Further, as shown in FIG. 6, the pouch container A of the present invention may be formed with an initial opening seal P on the upper flange portion 24 of the filling port member 2, and the contents of the pouch container A are sealed and stored. It is possible to provide a pouch container A with improved permeation resistance that blocks permeation of oxygen gas, carbon dioxide gas, water vapor, etc., and improved quality retention of contents. In particular, the pouch main body 1 that accommodates the contents is flexible, and thus has an effect that the product can be easily handled without causing breakage or scratches like a glass bottle or a blow bottle even when the product is transported.

そして、パウチ使用時においては、図７に示すように、パウチ容器の上部シール１５部分である前記充填口部材２の接合部２２（把持部２２）を持ち、パウチ容器Ａを安定して取り扱うことが可能であり、優れたハンドリング性を奏するパウチ容器Ａを提供することが可能である。 When the pouch is used, as shown in FIG. 7, the pouch container A has the joint 22 (gripping part 22) of the filling port member 2, which is the upper seal 15 part of the pouch container, and stably handles the pouch container A. It is possible to provide a pouch container A that exhibits excellent handling properties.

このように、本発明のパウチ容器Ａは、積層フィルムの周囲をシールしてなる自立可能なパウチ本体１と、該パウチ本体１の周囲の一側部に接合される、中央近傍に略円筒状の充填口を貫設した、接合部２２およびフランジ部２３，２４からなる熱可塑性樹脂の充填口部材２と、を備えるパウチ容器であって、接合部２２の、パウチ本体２の正面および裏面と接する円弧部分の半径Ｒ２を、充填口の開口部２１の半径Ｒ１以下にして、接合部２２の円弧部分を外方に突設させた簡単な構成により、前記パウチ本体１の側面形状が、略直円筒形状をなして、前記パウチ本体１の胴部保型性、自立安定性を向上することが可能である。さらには、優れた充填性、ハンドリング性を有するパウチ容器Ａを提供することが可能である。 As described above, the pouch container A of the present invention includes a self-supporting pouch body 1 formed by sealing the periphery of the laminated film, and a substantially cylindrical shape near the center that is joined to one side of the periphery of the pouch body 1. A thermoplastic resin filling port member 2 including a joint portion 22 and flange portions 23 and 24, and a front surface and a back surface of the pouch body 2 of the joint portion 22. The side surface shape of the pouch main body 1 is substantially the same by making the radius R2 of the arc portion in contact with the radius R1 of the opening portion 21 of the filling port and projecting the arc portion of the joint portion 22 outward. It is possible to improve the trunk shape retaining property and the self-supporting stability of the pouch body 1 by forming a right cylindrical shape. Furthermore, it is possible to provide the pouch container A having excellent filling properties and handling properties.

本発明のパウチ容器Ａは、上記例に限らず、内容物の注出性に優れた各種開口形状からなる注出部３３を有する注出口部材３を、前記充填口部材２へと取り付けてもよく、パウチ容器Ａの充填性のみならず注出性をも向上することが可能である。 The pouch container A of the present invention is not limited to the above example, and the spout member 3 having the spout portion 33 having various opening shapes excellent in the spoutability of contents can be attached to the filling port member 2. It is possible to improve not only the filling property of the pouch container A but also the pouring property.

この場合、前記注出口部材３の一例としては、図８（ａ）に示すように、注出口部材３の開口３１を塞ぐ、プルリング３５付き閉塞面３２を有する注出口部材３であってもよく、内容物の注出性を向上するとともに、初期開封前の不正開封防止の効果がある。 In this case, as an example of the spout member 3, a spout member 3 having a closing surface 32 with a pull ring 35 that closes the opening 31 of the spout member 3 as shown in FIG. In addition to improving the pouring property of the contents, it has the effect of preventing unauthorized opening before the initial opening.

前記注出口部材３の下方には、内方へと凸形状からなる段部３９が形成されており、該段部３９が、後述する、前記充填口部材２の上段フランジ部２４へと嵌合することにより、注出口部材３を充填口部材２へと取り付けることが可能である。 Below the spout member 3, a step 39 having a convex shape is formed inward, and the step 39 is fitted into an upper flange 24 of the filling port member 2 described later. By doing so, it is possible to attach the spout member 3 to the filling port member 2.

この注出口部材３は、パウチ容器Ａの初期開封時において、前記プルリング３５をつまみ上方へと引くことにより、注出部３３（ノズル３３）の開口３１を塞ぐ閉塞面３２が、薄肉部３４に沿って破断し、図８（ｂ）に示すように、略菱形状の開口３１を形成するものである。 When the pouch container A is initially opened, the spout member 3 has a closed surface 32 that closes the opening 31 of the pouring part 33 (nozzle 33) in the thin part 34 by pulling the pull ring 35 upward. It breaks along, and as shown in FIG.8 (b), the substantially rhombus-shaped opening 31 is formed.

そして、前記ノズル３３は、該ノズル３３の先端部分が、薄肉かつ外方へと開いた略ラッパ形状を有しており、液体等の内容物を注ぐ際にも液切れがよく、内容物がノズル３３の外側部分へと付着することを防ぐ効果がある。 The nozzle 33 has a substantially trumpet shape in which the tip portion of the nozzle 33 is thin and opens outwardly. There is an effect of preventing adhesion to the outer portion of the nozzle 33.

さらには、図９に示すように、前記注出口部材３の前記ノズル３３を閉封するための、キャップ４を形成してもよく、該キャップ４の内側に形成された内ネジ４６を、前記注出口部材３のノズル３３に形成された外ネジ３６へと螺着することにより、キャップ４を注出口部材３へと開閉自在に形成してもよい。 Furthermore, as shown in FIG. 9, a cap 4 for closing the nozzle 33 of the spout member 3 may be formed, and an internal screw 46 formed inside the cap 4 The cap 4 may be formed to be openable and closable to the spout member 3 by being screwed onto an external screw 36 formed on the nozzle 33 of the spout member 3.

そして、図１０に示すように、前記キャップ４を備える前記注出口部材３を、前記充填口部材２の上段フランジ部２４へと、打栓若しくは螺着して取り付けることにより、本発明のパウチ容器Ａを形成することが可能である。 Then, as shown in FIG. 10, the spout member 3 having the cap 4 is attached to the upper flange portion 24 of the filling port member 2 by being plugged or screwed, whereby the pouch container of the present invention is used. A can be formed.

このようにして形成したパウチ容器Ａは、注出口部材３の開口３１がプルリング３５付き閉塞面３２により密封されており、この状態で商品として店頭に並べることが可能であるとともに、注出口部材３に形成された前記プルリング３５付き閉塞面３２により、初期開封前の不正開封防止の効果がある。 In the pouch container A thus formed, the opening 31 of the spout member 3 is sealed by the closing surface 32 with the pull ring 35, and in this state, it can be arranged in the store as a product, and the spout member 3 The blocking surface 32 with the pull ring 35 formed in the above has an effect of preventing unauthorized opening before the initial opening.

そして、本発明のパウチ容器Ａの使用時には、前記注出口部材３に取り付けられた前記キャップ４を取り外して、注出口部材３のプルリング３５付き閉塞面３２を切除することにより、図１１に示すように、注出口部材を有する本発明のパウチ容器を形成することが可能である。 Then, when the pouch container A of the present invention is used, the cap 4 attached to the spout member 3 is removed, and the closing surface 32 with the pull ring 35 of the spout member 3 is excised, as shown in FIG. In addition, it is possible to form the pouch container of the present invention having a spout member.

特に、本発明のパウチ容器Ａは、図１１（ｂ）に示すように、パウチ本体１の側面形状が、略直円筒形状をなす点に特徴があり、パウチ容器Ａの高い自立安定性と胴部保型性とを奏することが可能である。 In particular, the pouch container A according to the present invention is characterized in that the side surface of the pouch body 1 has a substantially straight cylindrical shape, as shown in FIG. It is possible to achieve part retention.

そして、パウチ使用時において、図１２に示すように、パウチ本体１の上部シール１５である接合部２２（把持部２２）を把持して、パウチ容器Ａを安定かつ強固に保持することが可能であり、パウチ容器Ａのハンドリング性を向上するとともに、注出口部材３のノズル部３３を用いて、パウチＡの内容物を安定して注ぎ出すことが可能である。 When the pouch is used, as shown in FIG. 12, it is possible to hold the pouch container A stably and firmly by holding the joining portion 22 (the holding portion 22) which is the upper seal 15 of the pouch body 1. In addition, the handling property of the pouch container A can be improved, and the contents of the pouch A can be stably poured out using the nozzle portion 33 of the spout member 3.

前記充填口部材２の形状は、上記例に限定されるものではなく、接合部２２の円弧部分の半径Ｒ２が、充填口の開口部２１の半径Ｒ１以下である形状を有し、これに伴い、充填口部材２と、パウチ本体１の底部１４とが、略等しい長さを形成して、パウチ本体１の正面および裏面のフィルムが、前記充填口部材２とパウチ１の底部１４とをつなぐ直線状の柱を形成するものであれば、前記充填口部材２の形状は、特に限定されるものではない。また、前記注出口部材３は、上記例に限らず、注出性や使用性を向上するものであれば、後述する、ヒンジキャップ付き注出口部材３や逆止弁付き注出口部材３などを用いてもよく、さらには、前記充填口部材と前記注出口部材とが一体に形成されたものであってもよい。 The shape of the filling port member 2 is not limited to the above example, and has a shape in which the radius R2 of the arc portion of the joint portion 22 is equal to or less than the radius R1 of the opening portion 21 of the filling port. The filling port member 2 and the bottom portion 14 of the pouch body 1 form substantially equal lengths, and the front and back films of the pouch body 1 connect the filling port member 2 and the bottom portion 14 of the pouch 1. The shape of the filling port member 2 is not particularly limited as long as it forms a linear column. In addition, the spout member 3 is not limited to the above example, and a spout member 3 with a hinge cap, a spout member 3 with a check valve, etc., which will be described later, can be used as long as the spout and usability are improved. Further, the filling port member and the spout member may be integrally formed.

例えば、前記ヒンジキャップ付き注出口３の一例としては、図１３（ａ）に示すように、前記注出口部材３とキャップ４とが、屈曲自在なヒンジＨを介して一体に形成され、図１３（ｂ）に示すように、ヒンジキャップ４を片手で簡単に開くことが可能である。よって、キャップ４の開封をさらに容易に行なうことが可能であり、パウチ容器Ａの使用性を向上することが可能である。また、注出口部材３の開口部に初期開封シールＰを形成してもよく、商品購入前の不正開封防止の効果がある。 For example, as an example of the spout 3 with a hinge cap, as shown in FIG. 13A, the spout member 3 and the cap 4 are integrally formed via a bendable hinge H. As shown in (b), the hinge cap 4 can be easily opened with one hand. Therefore, the cap 4 can be opened more easily, and the usability of the pouch container A can be improved. Moreover, you may form the initial opening seal | sticker P in the opening part of the spout member 3, and there exists an effect of the unauthorized opening prevention before goods purchase.

さらには、前記逆止弁付き注出口部材３の一例としては、図１４（ａ）（ｂ）に示すように、弾性部材の中央部分に略十字形状の溝が形成されてなる逆支弁ｇを、前記注出口部材３の内部に設けた、逆止弁付き注出口３を用いてもよく、パウチに充填する内容物が、ハチミツ、マヨネーズ、整髪量などの、粘性を有する液体である場合であっても、所望量の内容物を簡単に注出することが可能であり、内容物の液切れがよく、さらなる使用性を向上したパウチ容器Ａを提供することが可能である。 Furthermore, as an example of the spout member 3 with a check valve, as shown in FIGS. 14 (a) and 14 (b), there is a reverse valve g in which a substantially cross-shaped groove is formed in the central portion of the elastic member. The outlet 3 with a check valve provided inside the outlet 3 may be used, and the content filled in the pouch is a liquid having viscosity, such as honey, mayonnaise, and hair amount. Even in such a case, it is possible to easily pour out the desired amount of the contents, and it is possible to provide the pouch container A in which the contents are sufficiently drained and the usability is further improved.

また、上記例では、充填口部材２と注出口部材３とが、別体で形成される例を示したが、これに限らず、充填口部材２と注出口部材３とが、着脱不可に一体をなす形状であってもよく、充填口部材２と一体に形成された注出口部材３の注出部を用いて、スムースかつ安定して内容物を充填することが可能であるとともに、使用時においても、内容物を安定して適量注ぎだすことが可能な構成としてもよい。 Moreover, in the said example, although the filling port member 2 and the spout member 3 showed the example formed separately, not only this but the filling port member 2 and the spout member 3 cannot be attached or detached. It may have an integral shape, and can be filled smoothly and stably using the pouring part of the spout member 3 formed integrally with the filling port member 2 and used. Even at times, it may be configured such that an appropriate amount of contents can be poured stably.

この場合、充填口部材２と注出口部材３とが一体に形成される場合の一例としては、図１５（ａ）（ｂ）に示すように、前記接合部２２の円弧部分の半径Ｒ２が、前記充填口の開口部２１の半径Ｒ１以下の充填口部材２の直上に略ラッパ状のノズルを有する注出口部材３を一体に形成してもよく、該注出口部材３へとキャップ４を螺着する構成であってもよい。 In this case, as an example of the case where the filling port member 2 and the spout member 3 are integrally formed, as shown in FIGS. 15 (a) and 15 (b), the radius R2 of the arc portion of the joint portion 22 is A spout member 3 having a substantially trumpet-shaped nozzle may be integrally formed immediately above the filling port member 2 having a radius R1 or less of the opening 21 of the filling port, and the cap 4 is screwed to the spout member 3. The structure to wear may be sufficient.

以上のように、本発明のパウチ容器Ａは、積層フィルムの周囲をシールしてなる自立可能なパウチ本体１と、該パウチ本体１の周囲の一側部に接合される、中央近傍に略円筒状の充填口を貫設した、接合部２２およびフランジ部２３，２４からなる熱可塑性樹脂の充填口部材２と、を備えるパウチ容器であって、接合部２２の、パウチ本体２の正面および裏面と接する円弧部分の半径Ｒ２を、充填口の開口部２１の半径Ｒ１以下にして、接合部２２の円弧部分を外方に突設させたことを特徴とする簡単な構成により、パウチ本体１の正面および裏面のフィルムが、前記充填口部材２とパウチ１の底部１４とをつなぐ柱を形成して、前記パウチ本体１の胴部保型性および自立安定性を向上することが可能である。 As described above, the pouch container A according to the present invention includes a self-supporting pouch body 1 formed by sealing the periphery of a laminated film, and a substantially cylindrical portion near the center that is joined to one side of the periphery of the pouch body 1. And a thermoplastic resin filling port member 2 including a joint portion 22 and flange portions 23 and 24, which are provided with a penetrating filling port, the front and back surfaces of the pouch body 2 at the joint portion 22. The arc portion of the pouch main body 1 has a simple configuration characterized in that the radius R2 of the arc portion in contact with the radius is equal to or less than the radius R1 of the opening 21 of the filling port, and the arc portion of the joint portion 22 protrudes outward. The front and back films can form a column connecting the filling port member 2 and the bottom 14 of the pouch 1, thereby improving the body shape retaining property and the self-supporting stability of the pouch body 1.

また、パウチ容器Ａに様々な工夫を講じることにより、パウチ容器Ａの注出性、充填性、ハンドリング性、使用性を向上した新しい形態のパウチ容器Ａを提供することが可能である。 Further, by taking various measures on the pouch container A, it is possible to provide a new type of pouch container A with improved pourability, filling property, handling property and usability.

前記充填口部材２の接合部２２は、パウチ容器Ａを把持する際の把持部２２となるため、接合部２２の上下方向の高さは、パウチ容器Ａを把持する際に、安定かつ強固に把持可能な高さを有することが望ましく、少なくとも１０ｍｍ以上、より望ましくは２０ｍｍ以上の高さが望ましい。これにより、パウチＡの開封時や閉封時にパウチ容器Ａを安定して保持することが可能である。 Since the joint portion 22 of the filling port member 2 becomes the grip portion 22 when gripping the pouch container A, the vertical height of the joint portion 22 is stable and strong when gripping the pouch container A. It is desirable to have a grippable height, and a height of at least 10 mm or more, more desirably 20 mm or more is desirable. Thereby, the pouch container A can be stably held when the pouch A is opened or closed.

また、充填口部材２の前記開口径２１（内径）は、１２ｍｍφ〜４０ｍｍφであることが望ましく、これにより、パウチＡ製造時において、内容物を充填する充填ノズルを前記充填口部材へと直接挿入して内容物を充填することが可能であり、充填口部材２の内側に内容物が付着することを防ぐことが可能である。さらには、パウチ底部の正面及び裏面間の側面幅Wが２０ｍｍ以上であることが望ましく、パウチＡの安定した自立性および胴部保型性を奏することが可能である。 Further, it is desirable that the opening diameter 21 (inner diameter) of the filling port member 2 is 12 mmφ to 40 mmφ, whereby a filling nozzle for filling the contents is directly inserted into the filling port member when the pouch A is manufactured. Thus, the contents can be filled, and the contents can be prevented from adhering to the inside of the filling port member 2. Furthermore, it is desirable that the side width W between the front surface and the back surface of the pouch bottom is 20 mm or more, so that the pouch A can have stable independence and body shape retaining properties.
