Description

【０００１】
【発明の属する技術分野】
本発明は、内容物の減少に伴って内側層が外側層から剥離し収縮する双胴容器に関するものである。
【０００２】
【従来の技術】
容器の使用態様によっては、一つの容器に異種の内容物を離隔して収容したい場合がある。例えば、二種類の液体を混合して使用する時には、使用直前に混合しないと効果がない場合がある。このような場合に、収容室が二つある容器を用意し、各収容室に各々の液体を収容しておき、使用時に、容器に取り付けた混合注出装置で二液を混合して注出できれば、容器が一つで済み、しかもコンパクトで使い勝手がよくなる。
【０００３】
この種の容器としては、内部が第一収容室にされた単層の第一胴部と、内部が第二収容室にされた単層の第二胴部とを備え、各胴部の上部に注出キャップが装着された一対の口筒部を備えた双胴容器が知られている。
【０００４】
【発明が解決しようとする課題】
ところで、容器には、容器の外観形状を保持するための外側層と、外側層に剥離可能に積層された内側層とを備え、内容物を常に内側層内に密封した状態に収容し、内容物の注出に伴って内側層が収縮するように構成された複数型のものがある。
【０００５】
しかし、双胴容器においては、このような複数型の容器は存在していなかった。
本発明は、このような従来技術の問題点に鑑みてなされたものであり、複数型の双胴容器を提供することを目的とする。
【０００６】
【課題を解決するための手段】
本発明は前記課題を解決するために、以下の手段を採用した。
以下に、本発明のポイントを簡単に述べる。
【０００７】
本発明は、樹脂で一体成形された容器であって、内部が第一収容室にされた第一胴部と、内部が第二収容室にされた第二胴部とを備え、係る第一及び第二胴部の各上部に注出キャップが装着される一対の口筒部を備えた双胴容器において、前記第一胴部と前記第二胴部はそれぞれ、互いに剥離可能に積層された内側層と外側層の少なくとも２層からなり、前記第一胴部と前記第二胴部とはそれぞれ対向配置された略同形状で略平坦な対向面を有し、当該対向面における前記内側層と前記外側層との間にそれぞれ、前記口筒部から前記対向面を通って底部内面に繋がり前記内側層と前記外側層との間を接合する接合部を備え、この接合部から１８０度離れた前記外側層の口筒部に空気孔を有することを特徴とする双胴容器である（請求項１に対応）。
【０００８】
本発明の双胴容器は、口筒部に装着される混合注出装置を作動して内容物を注出することにより容器内が減圧すると、前記内側層が負圧により引っぱられて外側層から剥離し収縮変形するため、容器本体の外観形状は変化しない。そして、各胴部を一体として取り扱うことができ、従って、容器を取り扱う者が、容器の使用・運搬等を行う際に操作を容易に行うことができる。
【０００９】
また、本発明の双胴容器は、前記対向面同士がその一端から他端までの略全長に亙って連結肉部によって連接して構成してもよい（請求項２に対応）。
【００１０】
さらに、本発明の双胴容器は、前記対向面同士がその一端から他端までの略全長に亙って相互に密着させて構成してもよい（請求項３に対応）。このようにすると、容器を取り扱う者が、容器を掴んで二つの胴部を互いに接近させる方向に力を加えても、前記対向面が相互に密着しているため口筒部が接近移動することはなく、容器の操作を容易に行うことができるからである。加えて、前記接合部は、前記対向面の幅方向中心部を通って前記口筒部から底部内面に繋がるものであってもよい（請求項４に対応）。
【００１１】
〈本発明の原材料〉
外側層は例えば高密度ポリエチレンで構成することができ、内側層は例えばナイロンで構成することができる。
【００１２】
尚、ナイロンは水分透過性が高いので、ナイロンの内側にガスバリア性に富む他の樹脂層（「アドマ−」等）を積層して内側層として、内側層の水分透過性を減少せしめることも可能である。
【００１３】
但し、外側層、内側層の原材料は前記の例に限るものではない。
【００１４】
【発明の実施の形態】
以下、本発明の実施の形態を図１から図６の図面に基いて説明する。
〔第１の実施の形態〕
図１は本発明による双胴容器の第１の実施の形態における斜視図であり、図２は断面図である。
【００１５】
双胴容器（以下、「容器」と記す。）１は、例えば高密度ポリエチレンで構成された外側層３と、例えばナイロンで構成された内側層５から成る一体成形品である。
【００１６】
容器１は、平行に並んで配された左右一対の胴部７，２７を備えており、各胴部７，２７は、それぞれ同一容積の第一収容室９及び第二収容室２９を内部に備えている。胴部７，２７の上部には、断面形状が略半円形をなす口筒部１１，３１が設けられている。胴部７，２７は互いに対向配置された対向面１３，３３を備えており、これら対向面１３，３３が連結肉部１５によって連結され、二つの胴部７，２７が一体化されている。係る対向面１３，３３は、口筒部１１，３１の先端から胴部７，２７の底部に至るまで、略平らな面で形成され、同一形状、同一寸法をなしている。
【００１７】
前記左右一対の胴部７，２７は、口筒部１１，３１の先端から胴部７，２７の底部に至るまで、その全体が外側層３と内側層５とを積層して構成されている。外側層３と内側層５は、帯状の接合部１７a，１７bにおいて接合されているが、接合部１７a，１７b以外の部位では外側層３と内側層５が当接しているだけで剥離可能になっている。
【００１８】
前記口筒部１１，３１には、内容物を混合し外部に注出する図示しない混合注出装置やキャップ等を両口筒部１１，３１にまたがって螺合固定するためのネジ山１９が設けられている。ここで、混合注出装置とは、第一収容室９に収容した第一の液体と第二収容室２９に収容した第二の液体をポンプアップし、これらを混合した後に注出するものをいう。
【００１９】
前記ネジ山１９の下部における外側層３には、接合部１７a，１７bから１８０度離れた部位に空気孔２１a，２１bが設けられている。空気孔２１a，２１bは外側層３だけを貫通しており、内側層５には貫通していない。
【００２０】
前記構成において、図示しない混合注出装置を作動させると、第一収容室９に収容された第一の液体と、第二収容室２９に収容された第二の液体とを混合した液体が外部に注出される。液体の減少に伴い前記第一収容室９及び第二収容室２９の内部圧力が低下し、各々の内側層５が外側層３から剥離し収縮する。内側層５のいずれの部位から剥離が始まるかは内側層５の肉厚分布によって決まるが、通常は接合部１７a，１７bから離れた位置から始まる。
【００２１】
内側層５の剥離が進行すると、外側層３と内側層５との間に形成される図示しない内部空間と容器１の外部間に圧力差が生じ、容器１の外部の空気が空気孔２１a，２１bを介して前記内部空間に流入して、前記圧力差が解消される。
【００２２】
図３は第１の実施の形態における容器１をブロー成形法により製造する方法を説明する図であり、型閉じ状態を示している。係る容器１をブロー成形するためには、図示のように、連結肉部１５の連結方向と直行する面を分割面（PL）とする一対の金型３５a,３５bと、外側層３を例えば高密度ポリエチレンで構成され、内側層５を例えばナイロンで構成された積層チューブ状の１本のパリソン３６を用意する。
【００２３】
各金型３５a,３５bには、両胴部７，２７を成形するためのキャビティ３７a,３７bを設けるとともに、両胴部７，２７を分離し且つ連結肉部１５を形成するための板状の分離部３９a，３９bを設け、この分離部３９a，３９bの端縁４１a，４１bを連結肉部１５に対応した形状にしておく。
【００２４】
両金型３５a,３５bの間に前記パリソン３６を挿入した後に、金型３５a,３５bを閉じると、パリソン３６の中央が分離部３９a，３９bによって挟圧されて接合され、連結肉部１５が形成されるとともに、パリソン３６の横断面形状が略「８」の字形になる。そして、分離部３９a，３９bによって二分されたパリソン３６内に、空気を吹き込み膨らませることによって、それぞれ胴部７，２７が成形され、各胴部７，２７内にそれぞれ第一収容室９及び第二収容室２９が成形される。
〔第２の実施の形態〕
図４は本発明による双胴容器の第２の実施の形態における斜視図であり、図５は断面図である。
【００２５】
第２の実施の形態と前述第１の実施の形態との相違点は、前記第一胴部７と前記第二胴部２７に設けられた互いに対向配置され略同形状で略平坦な対向面を、その一端から他端までの略全長に亙って相互に密着させたことである。胴部７，２７には互いに対向配置された対向面１３，３３を設けており、これら対向面１３，３３の全面が口筒部１１，３１の先端から胴部７，２７の底部に至るまで相互に密着されて、胴部７，２７が一体化されている。
【００２６】
係る対向面１３，３３は、略平らな面で形成され、同一形状、同一寸法をなしている。図中、第１の実施の形態と同一態様部分には同一符号を付して説明を省略する。
【００２７】
容器１を取り扱う者が、容器１を掴んで二つの胴部７，２７を互いに接近させる方向に力を加えても、前記対向面１３，３３が相互に密着しているため、胴部７，２７が各胴部７，２７の内側に湾曲することはない。
【００２８】
図６は第２の実施の形態における容器１をブロー成形法により製造する方法を説明する図であり、型閉じ状態を示している。係る容器１をブロー成形するためには、図示のように、横断面形状が半円形をしたキャビティ４３a,４３bを有する一対の金型４５a,４５bと、外側層３を例えば高密度ポリエチレンで構成され、内側層５を例えばナイロンで構成された積層チューブ状の２本のパリソン３６を用意する。
【００２９】
両金型４５a,４５bの間に二本のパリソン３６を挿入した後に、両金型４５a,４５bを閉じ、二本のパリソン３６に空気を吹き込み膨らませることによって、それぞれ半円形の胴部７，２７が形成され、各胴部７，２７内にそれぞれ第一収容室９及び第二収容室２９が成形される。
【００３０】

BACKGROUND OF THE INVENTION
The present invention relates to a catamaran container in which an inner layer peels from an outer layer and shrinks as the contents are reduced.
[0002]
[Prior art]
Depending on how the container is used, it may be desirable to store different contents in a single container. For example, when two types of liquids are mixed and used, there is a case where no effect is obtained unless they are mixed immediately before use. In such a case, prepare containers with two storage chambers, store each liquid in each storage chamber, and mix and discharge the two liquids with a mixing and pouring device attached to the container at the time of use. If possible, only one container is required, and it is compact and easy to use.
[0003]
This type of container includes a single-layered first body portion whose interior is a first storage chamber, and a single-layer second body portion whose interior is a second storage chamber. There is known a catamaran container having a pair of mouth tube portions with a pouring cap attached thereto.
[0004]
[Problems to be solved by the invention]
By the way, the container is provided with an outer layer for maintaining the outer shape of the container and an inner layer that is peelably laminated on the outer layer, and the contents are always contained in a sealed state in the inner layer. There are several types that are configured such that the inner layer contracts as the object is dispensed.
[0005]
However, such a multi-type container does not exist in the catamaran container.
The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a plurality of types of catamaran containers.
[0006]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems.
The points of the present invention will be briefly described below.
[0007]
The first aspect of the present invention is a container integrally formed of resin, and includes a first body portion whose inside is a first storage chamber, and a second body portion whose inside is a second storage chamber. And a catamaran container having a pair of mouth tube portions to which a pouring cap is mounted on each upper portion of the second body portion, the first body portion and the second body portion are laminated so as to be peelable from each other. It consists of at least two layers of an inner layer and an outer layer, and the first body part and the second body part have substantially the same shape and a substantially flat facing surface arranged facing each other, and the inner layer on the facing surface Between the inner tube and the outer layer, each of which is connected to the inner surface of the bottom portion through the opposing surface from the mouth tube portion, and is 180 degrees away from the bonding portion. a catamaran vessel characterized by having an air hole to the mouth tube portion of the outer layer (vs. in claim 1 ).
[0008]
When the inside of the container is decompressed by operating the mixing and dispensing device attached to the mouth tube portion to discharge the contents, the inner layer is pulled by the negative pressure and is pulled from the outer layer. Since it peels and shrinks, the external shape of the container body does not change. And each trunk | drum can be handled as integral, Therefore, the person who handles a container can operate easily, when performing use, conveyance, etc. of a container.
[0009]
Moreover, catamaran vessel of the present invention (corresponding to claim 2) wherein the opposing surfaces to each other may be constructed by concatenating the connecting wall portion over substantially the entire length from one end to the other.
[0010]
Moreover, catamaran vessel of the present invention (corresponding to claim 3) substantially may be constituted by close contact with each other over the entire length of the opposing surfaces to each other from one end to the other end thereof. In this way, even if the person handling the container applies a force in the direction of gripping the container and bringing the two body parts closer to each other, the mouth tube part moves closer because the opposing surfaces are in close contact with each other. This is because the container can be easily operated. In addition, the joint portion may be connected to the bottom inner surface from the mouth tube portion through the center portion in the width direction of the facing surface (corresponding to claim 4).
[0011]
<Raw material of the present invention>
The outer layer can be made of high density polyethylene, for example, and the inner layer can be made of nylon, for example.
[0012]
Since nylon has high moisture permeability, it is also possible to reduce the moisture permeability of the inner layer by laminating other resin layers (such as “Admer”) with excellent gas barrier properties inside the nylon. It is.
[0013]
However, the raw materials for the outer layer and the inner layer are not limited to the above examples.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.
[First Embodiment]
FIG. 1 is a perspective view of a catamaran container according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view.
[0015]
A catamaran container (hereinafter referred to as “container”) 1 is an integrally molded product comprising an outer layer 3 made of, for example, high-density polyethylene and an inner layer 5 made of, for example, nylon.
[0016]
The container 1 includes a pair of left and right barrels 7 and 27 arranged in parallel, and each barrel 7 and 27 includes a first storage chamber 9 and a second storage chamber 29 of the same volume inside. I have. Mouth tube portions 11 and 31 having a substantially semicircular cross section are provided on the upper portions of the body portions 7 and 27. The body parts 7 and 27 are provided with opposing surfaces 13 and 33 arranged so as to face each other. The opposing surfaces 13 and 33 are connected by the connecting meat part 15, and the two body parts 7 and 27 are integrated. The facing surfaces 13 and 33 are formed as substantially flat surfaces from the tips of the mouth tube portions 11 and 31 to the bottom portions of the body portions 7 and 27, and have the same shape and the same dimensions.
[0017]
The pair of left and right body parts 7 and 27 are formed by laminating the outer layer 3 and the inner layer 5 from the tip of the mouth tube parts 11 and 31 to the bottom part of the body parts 7 and 27. . The outer layer 3 and the inner layer 5 are joined at the belt-like joining portions 17a and 17b. However, the outer layer 3 and the inner layer 5 can be peeled only at the portions other than the joining portions 17a and 17b. ing.
[0018]
A screw thread 19 for screwing and fixing a mixture pouring device, a cap (not shown) that mixes contents and pours out to the outside across the mouth tube portions 11, 31 is formed in the mouth tube portions 11, 31. Is provided. Here, the mixing and dispensing device refers to a device that pumps up the first liquid stored in the first storage chamber 9 and the second liquid stored in the second storage chamber 29, mixes them, and then discharges them. Say.
[0019]
Air holes 21a and 21b are provided in the outer layer 3 at the lower part of the screw thread 19 at sites 180 degrees away from the joints 17a and 17b. The air holes 21 a and 21 b penetrate only the outer layer 3 and do not penetrate the inner layer 5.

In the above configuration, when a mixing and dispensing device (not shown) is operated, a liquid obtained by mixing the first liquid stored in the first storage chamber 9 and the second liquid stored in the second storage chamber 29 is externally applied. Be poured out. As the liquid decreases, the internal pressure of the first storage chamber 9 and the second storage chamber 29 decreases, and each inner layer 5 peels from the outer layer 3 and contracts. Which part of the inner layer 5 begins to peel depends on the thickness distribution of the inner layer 5, but usually starts from a position away from the joints 17a and 17b.
[0021]
When the peeling of the inner layer 5 proceeds, a pressure difference is generated between an inner space (not shown) formed between the outer layer 3 and the inner layer 5 and the outside of the container 1, and the air outside the container 1 becomes air holes 21a, The pressure difference is eliminated by flowing into the internal space via 21b.
