Description

本発明は、定形の外殻を形成する外層内に、可撓性に富んだ内袋を形成する内層を剥離自在に積層形成し、外観形状を変化させることなく、内容物の注出を可能とした合成樹脂製積層ブロー成形容器に関するものである。   The present invention allows the inner layer forming a flexible inner bag to be peeled and laminated inside the outer layer forming a regular outer shell, allowing the contents to be poured out without changing the external shape. This relates to a laminated blow molded container made of synthetic resin.

定形の外殻を形成する外層内に、可撓性に富んだ内袋を形成する内層を剥離自在に積層して構成した、一般にデラミボトルと称されるブロー成形壜体である、合成樹脂製積層ブロー成形容器が知られている。   Synthetic resin laminate, which is a blow-molded housing generally called a Delami bottle, which consists of an outer layer that forms a regular outer shell and an inner layer that forms a flexible inner bag that can be peeled off. Blow molded containers are known.

この合成樹脂製積層ブロー成形容器は、相溶性の殆どない外層パリソンと内層パリソンとを共押出しで積層パリソンに押出し成形し、この積層パリソンをブロー成形してブロー成形品を得、このブロー成形品の外層の一部に、内層の円滑な潰れ変形が得られるように、外層と内層との間に外気を侵入させるための吸気部を開設して構成される。   This synthetic resin laminated blow molded container is a coextruded outer layer parison and inner layer parison that are co-extruded to form a laminated parison, and this laminated parison is blow molded to obtain a blow molded product. In order to obtain a smooth crushing deformation of the inner layer, a suction part for allowing the outside air to enter between the outer layer and the inner layer is formed in a part of the outer layer.

そして、この合成樹脂製積層ブロー成形容器には、その口部に逆止弁付きの注出機能部品、例えばポンプが組付けられ、このポンプを操作して、内層内の内容物を、内層内に外気を侵入させずに、内層を潰し変形させながら、注出する。   The synthetic resin laminated blow-molded container is provided with a dispensing function part with a check valve, for example, a pump, at its mouth, and the pump is operated to transfer the contents in the inner layer to the inner layer. Pour out the inner layer without crushing the outside layer.

この内容物の注出に伴う内層の潰れ変形は一定したものではなく、このため場合によっては、ポンプによる内容物の吸上げを不能とする状態に変形してしまう、と云う不都合が発生する。   The crushing deformation of the inner layer accompanying the dispensing of the contents is not constant. For this reason, there is a problem that the contents are deformed so that the pump cannot suck the contents.

この不都合の発生を防止する従来技術として、外層と内層との間を、その全高さ範囲に亘って、縦帯状の接着層で接着固定し、この接着層で外層に固定された内層部分である不動部を、内層の変形規制部分として、潰れ変形形態を、内容物の移動を確保できるものとすると共に、内容物の移動通路形成部分としたものが知られている。
特開平０８−００１７６１号公報 As a conventional technique for preventing the occurrence of this inconvenience, an inner layer portion between the outer layer and the inner layer is bonded and fixed with a longitudinal belt-like adhesive layer over the entire height range, and is fixed to the outer layer with this adhesive layer. It is known that the non-moving part is used as an inner layer deformation restricting part, and the crushing deformation form is capable of ensuring the movement of the contents and the moving path forming part of the contents.
Japanese Patent Laid-Open No. 08-001761

また、この特許文献１にあっては、潰れ変形した内層の外観体裁が不体裁であるので、少なくとも外層を不透明として、潰れ変形した内層が容器の外観として表れることがないようにしている。   Moreover, in this patent document 1, since the appearance appearance of the inner layer that has been crushed and deformed is unnatural, at least the outer layer is made opaque so that the inner layer that has been crushed and deformed does not appear as the appearance of the container.

この特許文献１に開示された従来技術にあっては、確かに内容物を殆ど最後まで円滑に注出することができ、かつ潰れ変形した内層が容器の外観を害することがないのであるが、内容物の使い切り時期を、略正確に判断することができるように、容器の外観体裁を害することなく、容器外部から目視により内容物の残量を認識可能とすることが望まれている。   In the prior art disclosed in Patent Document 1, the contents can surely be smoothly poured out almost to the end, and the collapsed inner layer does not harm the appearance of the container. It is desired that the remaining amount of the contents can be visually recognized from the outside of the container without harming the appearance of the container so that the use-up time of the contents can be determined substantially accurately.

そこで、本発明は、上記した従来技術における要望を満たすべく創案されたもので、内容物の注出通路を最後まで形成すると共に、潰れ変形しない内層部分を外部から目視できるようにすることを技術的課題とし、もって容器の外観体裁を害することなく、容器外部から内容物の残量を目視で認識できるようにすることを目的とする。   Therefore, the present invention was devised to satisfy the above-described demand in the prior art, and is a technique for forming the content extraction passage to the end and making it possible to visually check the inner layer portion that is not crushed and deformed from the outside. It is an object of the present invention to make it possible to visually recognize the remaining amount of contents from outside the container without harming the appearance of the container.

上記技術的課題を解決する本発明の内、請求項１記載の発明に手段は、
定形の外殻を形成する合成樹脂製の不透明な外層と、この外層と剥離自在に積層され、内袋を形成する可撓性合成樹脂製の透明もしくは半透明な内層と、外層と内層とを、全高さ範囲に亘って接着固定する、縦帯状の透明もしくは半透明な接着層と、この接着層を避けた外層部分に開設された吸気部とから構成されること、
接着層と接着する外層部分の少なくとも一部を、透明もしくは半透明な窓壁部としたこと、
にある。 Among the present invention for solving the above technical problems, the means of the invention described in claim 1 is:
An opaque outer layer made of a synthetic resin that forms a fixed outer shell, a transparent or translucent inner layer made of a flexible synthetic resin that forms an inner bag, and is laminated with the outer layer in a peelable manner, and an outer layer and an inner layer , Comprising a longitudinal belt-like transparent or translucent adhesive layer that is adhesively fixed over the entire height range, and an air intake portion that is established in the outer layer portion avoiding this adhesive layer;
That at least a part of the outer layer part to be bonded to the adhesive layer is a transparent or translucent window wall part;
It is in.

この請求項１記載の発明にあっては、接着層が接着する外層の少なくとも一部を、透明もしくは半透明な窓壁部としたので、この窓壁部は、透明もしくは半透明な接着層および、潰れ変形不能となっている内層部分である不動部に対向位置することになる。   In the first aspect of the present invention, since at least a part of the outer layer to which the adhesive layer adheres is a transparent or translucent window wall portion, the window wall portion includes a transparent or translucent adhesive layer and Therefore, it is positioned opposite to the immovable portion, which is the inner layer portion that cannot be crushed and deformed.

このように、透明もしくは半透明な窓壁部、接着層そして内層の不動部が、不動に重なり合って位置するので、容器外部から、窓壁部を透して内層の不動部に位置している内容物を視認することができる。   In this way, the transparent or translucent window wall portion, the adhesive layer, and the immovable portion of the inner layer are positioned so as to overlap with each other, so that they are located from the outside of the container to the immovable portion of the inner layer through the window wall portion. The contents can be visually recognized.

外層に接着固定している内層の不動部は、最後まで内容物の通路を形成する部分であるので、この内層の不動部に位置している内容物の状態を観察することにより、内容物の残量をほぼ正確に判断することができる。   The immovable part of the inner layer that is adhesively fixed to the outer layer is the part that forms the passage of the contents until the end, so by observing the state of the contents located in the immovable part of the inner layer, The remaining amount can be determined almost accurately.

また、容器外部から目視される内層の不動部は、外層への接着固定により潰れ変形不能となった部分であるので、潰れ変形した内層部分である非接着部が直接に観察されることはなく、このため潰れ変形した非接着部の不体裁が、容器の外観として観察されることはない。   In addition, the immovable part of the inner layer visually observed from the outside of the container is a part that cannot be crushed and deformed by adhesion and fixation to the outer layer, so the non-adhered part that is the crushed and deformed inner layer part is not directly observed. For this reason, the appearance of the non-bonded portion that has been crushed and deformed is not observed as the appearance of the container.

請求項２記載の発明は、請求項１記載の発明の構成に、窓壁部を、容器の胴部の下端部に位置させたこと、を加えたものである。   The invention according to claim 2 is obtained by adding the window wall portion to the lower end portion of the body portion of the container in addition to the configuration of the invention according to claim 1.

この請求項２記載の発明にあっては、透明もしくは半透明な窓壁部を、容器の胴部の下端部に制限して位置させるので、容器の外観体裁に対する窓壁部の影響の程度が小さくなる。   In the invention according to claim 2, since the transparent or translucent window wall portion is limited and positioned at the lower end portion of the body portion of the container, the degree of the influence of the window wall portion on the appearance of the container is reduced. Get smaller.

特に、内容物が最後まで残留位置する胴部の下端部に窓壁部を位置させているので、内容物の少なくなった残量を略正確に観察できる。   In particular, since the window wall portion is positioned at the lower end portion of the body portion where the content remains to the end, the remaining amount of the content can be observed almost accurately.

請求項３記載の発明は、請求項１または２記載の発明の構成に、窓壁部が接着する接着層の横幅を、内容物の粘度の大小に応じて比例的に設定したこと、を加えたものである。   The invention described in claim 3 adds to the configuration of the invention described in claim 1 or 2 that the width of the adhesive layer to which the window wall portion adheres is set in proportion to the viscosity of the contents. It is a thing.

この請求項３記載の発明にあっては、接着層の横幅を大きくすると、その分、接着層に接着した内層の接着部が形成する内容物の通路の横幅が大きくなり、大きな流路断面積を得ることができて、粘度の大きい内容物でも円滑に注出することができるのであるが、内容物の残量が減少すると、通路の径方向に沿った厚みが比較的早く減少するので、この通路の径方向に沿った厚みの減少変化に伴う、窓壁部から見える内容物の状態変化により、例え粘度の大きい内容物であっても、その残量程度を、比較的正確に判断することが可能である。   In the invention according to claim 3, when the lateral width of the adhesive layer is increased, the lateral width of the passage of the content formed by the inner layer adhesive portion adhered to the adhesive layer is increased accordingly, and the flow passage cross-sectional area is increased. Can be smoothly poured out even with high viscosity content, but when the remaining amount of content decreases, the thickness along the radial direction of the passage decreases relatively quickly, Due to the change in the state of the contents seen from the window wall accompanying the decrease in the thickness along the radial direction of the passage, even if the contents have a large viscosity, the remaining amount is judged relatively accurately. It is possible.

請求項４記載の発明は、請求項１、２または３記載の発明の構成に、容器の中心軸に対して対称に配置された一対の接着層の一方を、窓壁部に接着させたこと、を加えたものである。   In the invention according to claim 4, in the configuration of the invention according to claim 1, 2, or 3, one of the pair of adhesive layers arranged symmetrically with respect to the central axis of the container is adhered to the window wall portion. , Is added.

この請求項４記載の発明にあっては、内層を略一定した状態で扁平に潰れ変形させることができるので、外層に固定した内層の不動部が安定して通路を形成することになり、これにより内容物の残量が、窓壁部が対向する通路部分に確実に位置することになる。   In the invention described in claim 4, since the inner layer can be flattened and deformed in a substantially constant state, the immovable portion of the inner layer fixed to the outer layer stably forms a passage. As a result, the remaining amount of the contents is surely located in the passage portion facing the window wall.

本発明は、上記した構成となっているので、以下に示す効果を奏する。
請求項１記載の発明にあっては、透明もしくは半透明な窓壁部、接着層そして最後まで内容物の通路を形成する部分である内層の不動部が、不動に重なり合って位置するので、容器外部から、窓壁部を透して内層の不動部が形成する通路内に位置している内容物を視認することができ、これにより内容物の残量をほぼ正確に判断することができる。 Since the present invention has the above-described configuration, the following effects can be obtained.
In the first aspect of the invention, the transparent or translucent window wall portion, the adhesive layer, and the immovable portion of the inner layer, which is the portion that forms the passage of the contents up to the end, are positioned so as to overlap with each other. From the outside, it is possible to visually recognize the contents located in the passage formed by the immovable portion of the inner layer through the window wall portion, and thereby it is possible to determine the remaining amount of the contents almost accurately.

また、容器外部から目視される内層の不動部は、外層への接着固定により潰れ変形不能となった部分であるので、内層の潰れ変形した非接着部が直接に観察されることはなく、このため潰れ変形した非接着部の不体裁が、容器の外観として観察されることはなく、潰れ変形した非接着部が容器の外観体裁を害する恐れがない。   In addition, the immovable part of the inner layer visually observed from the outside of the container is a part that cannot be crushed and deformed by adhesion and fixation to the outer layer, and therefore, the non-adhered part of the inner layer that has been crushed and deformed is not directly observed. Therefore, the appearance of the non-adhered portion that has been crushed and deformed is not observed as the appearance of the container, and the non-adhesive portion that has been crushed and deformed does not possibly harm the appearance of the container.

請求項２記載の発明にあっては、透明もしくは半透明な窓壁部が、容器の胴部の下端部に制限して位置するので、容器の外観体裁に対する窓壁部の悪影響の程度を、殆ど無くすことができる。   In the invention according to claim 2, since the transparent or translucent window wall portion is located limited to the lower end portion of the body portion of the container, the degree of the adverse effect of the window wall portion on the appearance of the container, Almost can be eliminated.

特に、内容物が最後まで残留位置する胴部の下端部に窓壁部が位置しているので、内容物の少なくなった残量を略正確に判断することができる。   In particular, since the window wall portion is located at the lower end portion of the body portion where the content remains to the end, the remaining amount of the content can be determined substantially accurately.

請求項３記載の発明にあっては、粘度の大きい内容物を、最後まで円滑に注出することができると共に、この粘度の大きい内容物の残量を正確に判断することができる。   In the invention according to the third aspect, the content having a high viscosity can be smoothly poured out to the end, and the remaining amount of the content having the high viscosity can be accurately determined.

請求項４記載の発明にあっては、内容物の残量が、窓壁部が対向する通路部分に確実に位置するので、内容物の残量の窓壁部を透しての視認が、確実に達成できる。   In the invention according to claim 4, since the remaining amount of the contents is reliably positioned in the passage portion where the window wall portion is opposed, the visual recognition through the window wall portion of the remaining amount of the contents is Can be achieved reliably.

以下、本発明の実施形態を、図面を参照しながら説明する。
図１は、口筒部に、組付けキャップ１１により注出ポンプ１０を組付けた、壜体状の本発明による容器１の基本的な構成の一実施形態を示すもので、容器１は、外殻体を形成する外層２と、外層２に剥離自在に積層された、撓み変形が自在な袋状の内層４と、容器１の全高さ範囲に亘って設けられた縦帯状の一対の接着層７とを積層させてブロー成形したもので、一方の接着層７が接着する外層２部分を窓壁部３として構成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a basic configuration of a casing-shaped container 1 according to the present invention in which a pouring pump 10 is assembled to a mouth tube portion by an assembly cap 11. An outer layer 2 that forms an outer shell, a bag-shaped inner layer 4 that is detachably laminated on the outer layer 2, and a pair of longitudinal strips that are provided over the entire height range of the container 1 The layer 7 is laminated and blow-molded, and the outer layer 2 portion to which one adhesive layer 7 adheres is configured as the window wall portion 3.

外層２は、ポリエチレン、ポリプロピレン等の合成樹脂材料で、必要とする自己形状保持能力を持った外殻体として構成され、窓壁部３以外の全部を、不透明としている。   The outer layer 2 is made of a synthetic resin material such as polyethylene or polypropylene, and is configured as an outer shell body having a necessary self-shape holding ability, and all except the window wall portion 3 is opaque.

内層４は、ナイロン、エチレンビニルアルコール共重合体、ポリエチレンテレフタレート等の外層２に対して相溶性の低い合成樹脂材料で充分に薄肉に成形され、その全体を透明もしくは半透明としている。   The inner layer 4 is formed sufficiently thin with a synthetic resin material having low compatibility with the outer layer 2 such as nylon, ethylene vinyl alcohol copolymer, polyethylene terephthalate, etc., and the whole is made transparent or translucent.

外層２および内層４に対して充分な接着性を発揮する接着性合成樹脂材で成形された接着層７は、その全体が透明もしくは半透明であり、そして全体が不透明である外層２は、その一部である窓壁部３だけを、透明もしくは半透明としている。   The adhesive layer 7 formed of an adhesive synthetic resin material that exhibits sufficient adhesion to the outer layer 2 and the inner layer 4 is transparent or translucent as a whole, and the outer layer 2 is opaque as a whole. Only a portion of the window wall 3 is transparent or translucent.

このように、透明もしくは半透明な窓壁部３は、透明もしくは半透明な接着層７および内層４と重合して位置する（図２参照）ので、外部から、窓壁部３、接着層７そして内層４の不動部６を透して、容器１の内部を視認することが可能となる。   Thus, the transparent or translucent window wall portion 3 is positioned by being overlapped with the transparent or translucent adhesive layer 7 and the inner layer 4 (see FIG. 2), so that the window wall portion 3 and the adhesive layer 7 are externally provided. Then, the inside of the container 1 can be visually recognized through the immovable portion 6 of the inner layer 4.

図１に示すように、接着層７を避けた外層２の口筒部部分には、外気を外層２と内層４との間に侵入させるための吸気部９が開設されているが、この吸気部９は、後加工により設けられているが、容器１の底部のピンチオフ部を底割れさせて形成してもよい。   As shown in FIG. 1, an air intake portion 9 for allowing outside air to enter between the outer layer 2 and the inner layer 4 is provided in the mouth tube portion of the outer layer 2 avoiding the adhesive layer 7. Although the part 9 is provided by post-processing, the part 9 may be formed by cracking the bottom of the pinch-off part of the container 1.

容器１の胴部８は円筒形状（図２参照）をしていて、一対の接着層７は、中心軸に対して前後に軸対称に位置しており、これにより内層４の外層２に接着していない非接着部５、すなわち外層２から剥離して潰れ変形ができる部分は、左右（図２において、上下）に２等分された状態で位置する。   The body portion 8 of the container 1 has a cylindrical shape (see FIG. 2), and the pair of adhesive layers 7 are positioned axially symmetrically with respect to the central axis so as to adhere to the outer layer 2 of the inner layer 4. The non-bonded portion 5 that is not formed, that is, the portion that can be crushed and deformed by being separated from the outer layer 2 is located in a state of being divided into two equal parts on the left and right (up and down in FIG. 2).

内層４は、収納した内容物Ｎの注出に従って、左右に２等分された両非接着部５を潰れ変形させるが、両非接着部５の潰れ変形は、両側端に全高さ範囲に亘って不動に位置する不動部６により規制されながら行われるので、略等しい形態で進行する。   The inner layer 4 crushes and deforms both the non-adhered portions 5 that are divided into right and left according to the pouring of the stored contents N. The crushing deformation of both the non-adhered portions 5 extends over the entire height range at both side ends. Since it is performed while being regulated by the immovable portion 6 that is positioned immovably, it proceeds in a substantially equal form.

このように、内層４の潰れ変形は、外層２に不動に接着した内層４の不動部６を支持箇所として、２等分された両非接着部５が接近して当接し合う形態で進行するので、この不動部６の内側には内容物Ｎが最後まで位置することになる。   In this way, the crushing deformation of the inner layer 4 proceeds in a form in which the two non-adhered portions 5 which are divided into two equally approach each other with the fixed portion 6 of the inner layer 4 fixedly bonded to the outer layer 2 as a support location. Therefore, the content N is positioned to the end inside the fixed portion 6.

この不動部６は、接着層７に沿って形成されるものであるので、容器１の全高さ範囲に亘って形成され、このため不動部６の内側は、残存した内容物Ｎの最後の注出通路を形成することになる。   Since the non-moving portion 6 is formed along the adhesive layer 7, it is formed over the entire height range of the container 1, so that the inside of the non-moving portion 6 is the last note of the remaining content N. An exit passage will be formed.

一方の不動部６は、接着層７を介して窓壁部３と対向しているので、内容物Ｎの残量が少なくなって、不動部６の内側に形成された注出通路の形態が変化する（図３参照）と、この変化を、窓壁部３を透して、濃淡の変化、明暗の変化、もしくは内層４の形態変化として観察でき、これにより内容物Ｎの残量を、ほぼ正確に判断することができる。   Since one stationary part 6 is opposed to the window wall part 3 through the adhesive layer 7, the remaining amount of the contents N is reduced, and the form of the extraction passage formed inside the stationary part 6 is reduced. When changed (see FIG. 3), this change can be observed through the window wall 3 as a change in shading, a change in light and darkness, or a change in form of the inner layer 4, whereby the remaining amount of the content N is It can be judged almost accurately.

図４は、窓壁部３の他の実施形態を示すもので、窓壁部３を胴部８の下端部に制限して設けており、このように窓壁部３の大きさを、内容物Ｎの残量を観察することができる程度に制限することにより、窓壁部３が容器１の外観体裁に与える影響を小さくなるようにしている。   FIG. 4 shows another embodiment of the window wall 3, and the window wall 3 is limited to the lower end of the body 8, and the size of the window wall 3 is thus described By limiting the remaining amount of the object N to such an extent that it can be observed, the influence of the window wall portion 3 on the appearance of the container 1 is reduced.

図５は、不動部６を形成する接着層７の他の実施例を示すもので、図３に示した実施例に比べて、接着層７の横幅を、内容物Ｎの粘度の増大に従って、略比例的に設定したものである。   FIG. 5 shows another embodiment of the adhesive layer 7 that forms the immovable portion 6. Compared with the embodiment shown in FIG. 3, the lateral width of the adhesive layer 7 is increased according to the increase in the viscosity of the contents N. It is set approximately proportionally.

すなわち、内容物Ｎの粘度が大きくなるに従って、接着層７の横幅を大きくすると、内容物Ｎの通路の底面を形成する不動部６の横幅が大きくなり、これにより流路断面積の大きな通路を確保し易くなる。   That is, when the width of the adhesive layer 7 is increased as the viscosity of the contents N increases, the width of the immobile portion 6 that forms the bottom surface of the passage of the contents N increases, whereby a passage having a large channel cross-sectional area is formed. It becomes easy to secure.

また、このように形成される通路の底面の幅が大きいので、内容物Ｎの残量が少なくなると、通路の厚み幅である容器１の径方向に沿った幅が、急速に減少し始めるので、この通路の厚み幅の減少程度を観察することにより、内容物Ｎの残量を正確に判断することができる。   In addition, since the width of the bottom surface of the passage formed in this way is large, the width along the radial direction of the container 1 which is the thickness width of the passage starts to decrease rapidly when the remaining amount of the contents N decreases. By observing the degree of decrease in the thickness width of the passage, the remaining amount of the content N can be accurately determined.
