真空ポンプ付二重容器用の内容器Inner container for double container with vacuum pump

本発明は、真空ポンプによって内容物を吸引して外部に排出する二重容器(外容器と内容器の二重構造からなる容器)に用いられる内容器に関する。 The present invention relates to an inner container used for a double container (a container having a double structure of an outer container and an inner container) that sucks out contents by a vacuum pump and discharges the contents to the outside .

近年の省資源化の要望に応えて、例えばシャンプー、リンスや石けん液等のポンプ付二重容器の場合には、ポンプと外容器はそのまま使い、内容物であるシャンプー等を充填した内容器のみを変換して廃棄するカートリッジ式の使用形態をとっているのが一般的である。 In response to demands for resource saving in recent years, for example, in the case of double containers with pumps such as shampoo, rinse and soap solution, the pump and outer container are used as they are, and only the inner container filled with shampoo etc. as the contents It is common to use a cartridge-type usage form that converts and discards.

しかし、内容器はポンプで内容物が吸い出されて行くと、真空作用により収縮するが、この収縮したときの形状は不定形となり、廃棄処分に際して減容化率が小さい、という問題がある。 However, when the contents are sucked out by the pump, the inner container contracts due to a vacuum action, but the shape when contracted becomes indefinite, and there is a problem that the volume reduction rate is small at the time of disposal.

そこで、この減容化率を促進する目的で、特許文献1には、ポンプを口部に取着可能とした薄肉容器として、内容物の吐出に応じて容器の潰れ方を規制するようにした薄肉容器において、口部にポンプを取着し、胴周壁を薄肉とした容器であって、胴周壁に柱部を設け、内容物の吐出時に胴周壁の潰れ方を規制するようにした二重容器が紹介されている。 Therefore, in order to accelerate the volume reduction ratio, Patent Document 1, as a thin-walled container and attachable to the pump to the mouth portion, so as to regulate the crushing way of the inner container in accordance with the discharge of the contents in thin containers, and attach the pump to the mouth, a container inner to the cylinder jacket and thin, the pillar portion is provided in the cylinder jacket, and so as to regulate the crushing way of the cylinder jacket during the ejection of the contents Double containers are introduced.

しかし、この二重容器の場合、容器の胴周壁に柱部を設けているため、潰れた時の胴部形状は細く変形するものの、縦方向の長さ寸法は変化せず、全体としての減容化率はそれほど大きくならないHowever, in this double container, since the provided column portion to the cylinder jacket of the inner container, although the barrel shape when collapsed thinning deformation, the longitudinal length does not change, as a whole volume reduction rate is not so big name et al.

また、特許文献2には、変形し難い外容器と容易に変形可能な内容器とを含み、容器口部に内容器の口部に密封した流動物注出手段を装着してなる流動物の注出容器において、内容器が互に直交する方向へ延出した4つの略三角形の折畳部を中央で相互に連通すると共に、互に隣接する折畳部の直角部を上下逆に位置させた形状を有する袋状容器からなり、収縮時に折畳部が直交する4方向へ折り畳まれて平面十字状の収縮形状を呈するものが紹介されている。   Further, Patent Document 2 includes an outer container that is difficult to deform and an inner container that can be easily deformed, and is provided with a fluid pouring means attached to the mouth of the inner container at the mouth of the container. In the dispensing container, four substantially triangular folds, in which the inner containers extend in directions perpendicular to each other, communicate with each other at the center, and the right angle parts of the folds adjacent to each other are positioned upside down. It has been introduced that is formed of a bag-like container having a different shape and is folded in four directions perpendicular to each other when the fold is contracted to exhibit a flat cross-shaped contracted shape.

しかし、この容器の場合も、内容器収縮したときに平面視十字状を呈することはあっても、縦方向の収縮はしないことから、減容化率は大きくないHowever, in the case of the inner container, even able to exhibit plan view cross shape when the inner container contracts, since it does not in the longitudinal shrinkage, volume reduction ratio is not large.

更に特許文献3には、 ポンプ付き二重容器の内容器の潰れ変形形態が、設定したものとなるようにすることにより、確実で安定した内容物の吐出動作を得ることを目的とするものとして、潰れ変形自在な内容器と、内容器を収納保持する変形しない外容器と、両容器に組付いて、ポンプ動作により内容器の内容物を吐出するポンプとを有し、内容器の胴部にリブ条を形成して、潰れ変形を一定形態に規制すると共に、内容器と外容器との間に外気を導入する通気部を設けて、潰れ変形を円滑に行なわせる二重容器が紹介されている。 Furthermore, in Patent Document 3, the purpose is to obtain a reliable and stable discharge operation of the contents by making the collapsed deformation form of the inner container of the double container with a pump set. An inner container that can be crushed and deformed; an outer container that retains and holds the inner container; and a pump that is assembled to both containers and discharges the contents of the inner container by a pump operation. A double container that introduces a rib section to restrict crushing deformation to a certain form and provides a ventilation part for introducing outside air between the inner container and the outer container to facilitate crushing deformation is introduced. ing.

しかし、この容器の場合も、リブ条は胴部において方向に形成されているため、収縮は前記2つの特許文献と同様に高さ方向においては発生せず、減容化率は高さ方向においては十分でない。 However, in the case of the inner container, the ribs conditions because it is formed in the longitudinal direction in the body portion, shrinkage does not occur in the two patent documents as well as the height direction, volume reduction ratio height Not enough in direction.

本発明は、内容器の収縮方向(潰れ方向)を径方向のみならず縦方向にも生じさせ、ゴミとして廃棄する際の減容化率を最大化することができる真空ポンプ付二重容器の内容器を提供することを目的とするThe present invention also causes the vertical direction as well as the inner container shrinkage direction (crushing direction) radial only, the double container with a vacuum pump capable of maximizing the volume reduction ratio when discarded as waste The purpose is to provide an inner container .

上記目的を達成するため、本発明は、真空ポンプによって内容物を吸引して外部に排出する二重容器に用いられる内容器であって、前記内容器は、平面視多角形の上面部と、前記上面部と平面視同一の多角形からなる底面部と、前記上面部と前記底面部とを連結する側面部を有し、前記上面部の多角形と前記底面部の多角形は、平面視においてその中心点から相対的に一定角度回転変位しており、前記内容器の側面部には、前記上面部の多角形の全ての頂点と、当該全ての頂点に一対一で対応する前記底面部の多角形の全ての頂点とを結ぶ山折れ癖線が形成されている、ことを特徴とする。 In order to achieve the above object, the present invention is an inner container used for a double container that sucks out contents by a vacuum pump and discharges the contents to the outside. The upper surface portion has a bottom surface portion made of the same polygon in plan view, and a side surface portion connecting the upper surface portion and the bottom surface portion, and the polygon of the upper surface portion and the polygon of the bottom surface portion are in plan view. The side surface of the inner container has a polygonal vertex of the upper surface portion, and the bottom surface portion corresponding to all the vertexes one-to-one. A mountain fold line connecting all the vertices of the polygon is formed.

本発明によれば、ポンプによって内容器に収容された内容物が外部に放出されると、内容器は減圧によって収縮するが、その時、内容器の側面に設けた山折れ癖線によって、捻じれの作用が生じ、かつこの捻じれ作用によって、内容器は縦方向と径方向の両方向に収縮するため、ゴミとして廃棄する際の減容化率を大きくすることができる According to the present invention, when the contents contained in the inner container are discharged to the outside by the pump, the inner container contracts due to the reduced pressure, but at that time, the inner container is twisted by the mountain folds provided on the side surface of the inner container. As a result, and the twisting action causes the inner container to shrink in both the longitudinal direction and the radial direction, the volume reduction rate when discarded as garbage can be increased .

また、内容器の側面の隣り合う山折れ癖線に囲まれた領域内に、更に谷折れ癖線及び山折れ癖線を適宜に配置すれば、収縮動作もスムーズで、かつ想定した形状により潰れやすくなる。  In addition, if a valley fold line and a mountain fold line are appropriately arranged in an area surrounded by adjacent mountain fold lines on the side surface of the inner container, the contraction operation is smooth and the crushed shape is assumed. It becomes easy.

Embodiments according to the present invention will be described in detail with reference to FIGS.
FIG. 1 shows a double container with a vacuum pump equipped with an inner container 5 according to the present invention, where 1 is an outer container, 2 is a lid of the outer container 1, 3 is a vacuum pump, 4 is a pump cylinder, 4a is It is a pump suction nozzle. The outer container 1 is molded from a hard resin, and the inner container 5 is blow-molded from a deformable soft resin. The double container with a vacuum pump is a pump that pumps out the contents stored in the inner container using a vacuum pump. The cylinder part of the pump is inserted into the inner container to suck the contents. When it is discharged to the outside, it is a double container having a structure in which the inner container depressurizes according to the volume of the sucked contents.

内容器5は、変形が容易なように軟質樹脂製で、かつ薄く形成され、ポンプ3側の取り付けキャップ6に対して口部5aに設けたねじ部7により取り付けられている。
この内容器5は、平面視で六角形に形成した上面部10と、当該上面部10と同じく平面視で六角形に形成したし底面部11と、側面部9を有している。ともに六角形に形成した上面部10と、底面部11は、図2に示す通り、平面視において同一中心点を中心として、相対的に一定角度回転変位しており、六角形からなる上面部10の各頂点と、六角形からなる底面部11の各頂点は、一対一で対応する山折れ癖線8によって結ばれている。
The inner container 5 is made of a soft resin and is formed thin so as to be easily deformed, and is attached to a mounting cap 6 on the pump 3 side by a screw portion 7 provided in the mouth portion 5a.
The inner container 5 has a top surface portion 10 that is formed in a hexagonal shape in plan view, a bottom surface portion 11 that is formed in a hexagonal shape in a plan view like the upper surface portion 10, and a side surface portion 9. As shown in FIG. 2, the upper surface portion 10 and the bottom surface portion 11 both formed in a hexagonal shape are rotationally displaced at a relatively constant angle around the same center point in plan view, and the upper surface portion 10 made of a hexagon. And the vertices of the bottom face portion 11 made of a hexagon are connected by a corresponding one-to-one mountain fold line 8.

山折れ癖線8は、内容器5が収縮する際に、山折れするように予め癖が付けられた線(筋)であり、図2に示すとおり、側面部9を捩じるような形状(スクイズした形状)で配置されており、内容器5が収縮する際、内容器5の側面部9は、この山折れ癖線8に沿って捩じられて変形し、内容器5はその縦方向(上下方向)及び径方向(幅方向)に収縮するようになっている。本実施例では、山折れ癖線8が、内容器5の縦方向軸に対し、側面視で3〜5度傾斜するように、上面部10と底面部11は、同一中心点を中心として、相対的に一定角度回転変位するようになっている。  The mountain crease line 8 is a line (streak) that has been pre-creased so that it folds when the inner container 5 contracts, and has a shape that twists the side surface 9 as shown in FIG. When the inner container 5 contracts, the side surface portion 9 of the inner container 5 is twisted and deformed along the mountain fold line 8, and the inner container 5 It shrinks in the direction (vertical direction) and the radial direction (width direction). In the present embodiment, the top surface portion 10 and the bottom surface portion 11 are centered on the same center point so that the mountain fold ridge 8 is inclined 3 to 5 degrees in a side view with respect to the longitudinal axis of the inner container 5. It is relatively displaced by a fixed angle.

上面部10、底面部11、隣り合う2つの山折れ癖線8、とで形成されるほぼ平行四辺形形状となる内容器5の側面領域は、平面であっても良く、又は内容器5の径方向内側に湾曲する凹面であっても良い。図2に示すとおり、内側に湾曲した凹面とした場合、側面9は、内容器5が収縮する際に、より径方向内側に取り込まれていくようにすることができる。The side region of the inner container 5 having a substantially parallelogram shape formed by the upper surface portion 10, the bottom surface portion 11, and the two adjacent mountain fold lines 8 may be a plane, or the inner container 5 A concave surface curved inward in the radial direction may be used. As shown in FIG. 2, when the concave surface is curved inward, the side surface 9 can be taken in more radially inward when the inner container 5 contracts.

本発明は、内容器5に設けた山折れ癖線8のみでも、十分な減容効果を発揮するものであるが、内容器5をより想定した形にスムーズに変形できる(潰すことができる)ように、本実施例では、以下に示す谷折れ癖線12を更に有している。The present invention exhibits a sufficient volume-reducing effect even with only the mountain folds 8 provided in the inner container 5, but can be smoothly deformed (can be crushed) into a more assumed shape of the inner container 5. Thus, in the present embodiment, it further has a valley fold line 12 shown below.

図中12は、内容器5の側面部9に設けた谷折れ癖線である。この谷折れ癖線12は、隣り合う2つの山折れ癖線8と、上面部10及び底面部11とによって形成されるほぼ平行四辺形形状の側面領域内であって、山折れ癖線8の傾斜方向と同方向の対角線上に形成されている。  In the figure, 12 is a trough crease provided on the side surface portion 9 of the inner container 5. The valley fold line 12 is in a side region of a substantially parallelogram formed by two adjacent mountain fold lines 8 and the upper surface portion 10 and the bottom surface portion 11. It is formed on a diagonal line in the same direction as the tilt direction.

図3は、ポンプ3により内容物aが吸引されて内容器5が最終段階まで潰れた状態を示す断面図であり、使用開始時に例えば5度変位していた上面部10と底面部11の位置関係は、上記捩じり作用によって相対回転する。この捩じり作用が大きければ大きいほど、内容器5の縦方向及び径方向の収縮は大きくなる。 FIG. 3 is a cross-sectional view showing a state in which the content a is sucked by the pump 3 and the inner container 5 is crushed to the final stage , and the positions of the top surface portion 10 and the bottom surface portion 11 that have been displaced, for example, 5 degrees at the start of use. The relationship is relatively rotated by the twisting action. The greater the twisting action, the greater the shrinkage of the inner container 5 in the longitudinal and radial directions.

このようにして、内容器5の側面部9は一方向に捩じられるようにして潰れ、縦方向及び径方向に縮小し、減容化率を大きくし、ゴミとして廃棄する際の負荷を軽減できる。 In this way, the side surface portion 9 of the inner container 5 is crushed so as to be twisted in one direction, and is reduced in the longitudinal and radial directions, increasing the volume reduction rate and reducing the load when it is disposed as garbage. it can.

また、谷折れ癖線12を、隣り合う2つの山折れ癖線8と、上面部10及び底面部11とによって形成されるほぼ平行四辺形形状の側面領域内に形成することで、当該谷折れ癖線12が無い場合に比べて、事前に想定した状態に内容器5を潰すことができる。即ち、当該谷折れ癖線12が無い場合には、個々の内容器によって変形の仕方が微妙に相違するが、谷折れ癖線12を設けることで、どの内容器であっても、ほぼ図3に示す一定形状に変形させることが可能となる。  Further, by forming the valley fold line 12 in the side region of the substantially parallelogram formed by the two adjacent mountain fold lines 8, the top surface part 10 and the bottom surface part 11, the valley fold line is formed. Compared to the case where there is no shoreline 12, the inner container 5 can be crushed in a state assumed in advance. That is, in the case where there is no valley fold line 12, the manner of deformation is slightly different depending on the individual inner container, but by providing the valley fold line 12, any inner container can be almost as shown in FIG. It becomes possible to make it deform | transform into the fixed shape shown in FIG.

なお、上記実施例で示した内容器5の上面部及び底面部は六角形としているが、三角形、5角形、8角形等、多角形であれば良く、特に限定されない In addition, although the upper surface part and bottom surface part of the inner container 5 shown in the said Example are made into hexagons, they should just be polygons, such as a triangle, a pentagon, and an octagon, and are not specifically limited .

また、山折れ線8は、側面部9においてすべて同一方向に約3〜5°傾けることにより、側面部9の捻じれ方向が定まるが、この傾ける角度は、側面部9の面積及び高さ、直径、側面部9の軟度等から最良のものが選定される。 Also, the mountain fold lines 8, by tilting about 3 to 5 ° in the same direction all the side portions 9, but determined twist direction of the side portion 9, the tilting angle, the area of the side surface portion 9 and the height, diameter The best one is selected based on the softness of the side surface portion 9 and the like.

図1において、15はエアーの流入孔、16は供回り防止ストッパーである。   In FIG. 1, 15 is an air inflow hole, and 16 is a rotation prevention stopper.

以上のとおり、本発明によれば、内容物の放出に伴う内容器の収縮が、内容器の側面に形成される山折れ癖線によって捩じられるように収縮し、内容器の縦方向及び径方向の両方向に収縮することにより、ゴミとして廃棄する際にコンパクト化され、廃棄の負荷を軽減することができる。  As described above, according to the present invention, the shrinkage of the inner container accompanying the discharge of the contents shrinks so as to be twisted by the mountain folds formed on the side surface of the inner container, and the longitudinal direction and diameter of the inner container By contracting in both directions, it is compact when discarded as garbage, and the load of disposal can be reduced.
