Description

本発明は、粘稠性のある内容物を吐出可能に収納する、合成樹脂製のスクイズ変形および積層剥離可能な吐出容器に関するものである。   The present invention relates to a synthetic resin squeeze deformable and delaminated discharge container that accommodates viscous contents in a dischargeable manner.

マヨネーズとかケチャップ等の粘稠性のある内容物を吐出可能に収納する容器として、減容変形および復元変形が可能な、合成樹脂製ボトル型のスクイズ容器が、広く使用されている。   As a container for storing viscous contents such as mayonnaise and ketchup in a dischargeable manner, a synthetic resin bottle-type squeeze container capable of volume reduction deformation and restoration deformation is widely used.

このスクイズ容器の収納される粘稠性内容物の多くは、酸素との接触を嫌うものであるが、この粘稠性内容物の品質を長期間に亘って良好に維持し、また粘稠性内容物の速やかで良好な吐出動作を得ることができるように、積層剥離構造を有するデラミボトル型容器により吐出容器を構成する従来技術が知られている。   Most of the viscous contents stored in this squeeze container do not like contact with oxygen, but the quality of the viscous contents is maintained well over a long period of time, and Conventional techniques are known in which a discharge container is constituted by a Delami bottle type container having a delamination structure so that a quick and good discharge operation of contents can be obtained.

この上記した従来技術にあっては、外層体と内層体の成形樹脂材料の選択と組合せ、および外層体と内層体の弾性率の設定と組合せにより、適当なスクイズ性を得るようにしている。
特開2004−196357号公報

JP 2004-196357 A

しかしながら、上記した従来技術にあっては、容器本体の胴部を押圧して粘稠性内容物を吐出させた際、押圧操作により胴部に形成された陥没部分の外層体部分が、速やかには復元変形しない場合がある、と云う問題があった。   However, in the above-described prior art, when the body portion of the container body is pressed to discharge the viscous contents, the outer layer body portion of the depressed portion formed in the body portion by the pressing operation is quickly Has a problem that it may not be restored and deformed.

これは、図8に示すように、外層体ロと内層体ハから成るデラミボトル型の容器本体イは、その胴部ニを平滑な壁構造で構成しているので、内容物を吐出させるべく、胴部ニを前後から押圧して陥没弾性変形させて、図9に示すように、押圧時陥没部aを形成すると、この押圧時陥没部aの周方向の端部である側端折れ曲がり部bが、反転屈曲に近い状態となる。   This is because, as shown in FIG. 8, the Delami bottle type container main body (a) comprising the outer layer body (B) and the inner layer body (C) is configured with a smooth wall structure in the body (d), so that the contents can be discharged. When the body portion d is pressed from the front and back to be elastically deformed by depression and as shown in FIG. 9, a depression portion a is formed at the time of pressing, the side bent portion b which is an end in the circumferential direction of the depression portion a at the time of pressing is formed. However, it will be in the state close | similar to inversion bending.

このため、外層体ロの復元変形のための弾力が、この側端折れ曲がり部bで受け止められてしまい、速やかに復元変形ができなくなるためであると思われる。   For this reason, it is considered that the elasticity for restoring deformation of the outer layer body B is received by the side edge bent portion b, and the restoring deformation cannot be performed promptly.

この問題点は、外層体ロの弾力を大きくすることにより解消されるが、図8および図9に示した構成のまま、押圧時陥没部aの速やかな復元変形を得ることができる程度に、外層体ロの弾力を大きくすると、胴部ニのスクイズ変形に要する操作力が増大し、その分、円滑なスクイズ変形動作が得られなくなる、と云う問題が発生する。   This problem is solved by increasing the elasticity of the outer layer body B, but with the configuration shown in FIGS. 8 and 9, it is possible to obtain a quick restoration deformation of the depressed portion a when pressed, When the elasticity of the outer layer body B is increased, the operation force required for the squeeze deformation of the body part D increases, and a problem arises that a smooth squeeze deformation operation cannot be obtained accordingly.

そこで、本発明は、上記した従来技術における問題点を解消すべく創案されたもので、胴部の外層体の弾力を増大することなく、押圧時陥没部の速やかな復元変形を得ることを技術的課題とし、もって適正なスクイズ性を維持したまま、速やかに吐出可能状態に復帰することができるようにすることを目的とする。   Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and is a technique for obtaining a quick restoration deformation of a depressed portion during pressing without increasing the elasticity of the outer layer body of the trunk portion. It is an object of the present invention to make it possible to quickly return to a dischargeable state while maintaining an appropriate squeeze property.

本発明による吐出容器は、スクイズ変形可能で、復元自在な可撓性を有する外層体と、この外層体に剥離可能に積層され、粘稠性内容物を収納して、自在に減容変形する内層体とからブロー成形された合成樹脂製の容器本体を有している。   The discharge container according to the present invention is a squeezable deformable and flexible outer layer body, and is laminated on the outer layer body so as to be peelable, and accommodates viscous contents and can be freely reduced in volume. It has a synthetic resin container body blow-molded from the inner layer body.

この容器本体の、押圧操作力が加えられる胴部部分には、中央周溝が周設されている。   A central circumferential groove is provided around the body portion of the container body to which a pressing operation force is applied.

粘稠性内容物を吐出させるべく、胴部を押圧すると、この押圧により陥没形成される押圧時陥没部の側端折れ曲がり部は、屈曲状に折れ曲がることなく、大きな曲率半径で折れ曲がる。   When the body portion is pressed to discharge the viscous contents, the side end bent portion of the depressed depression portion formed by depression is bent with a large curvature radius without being bent.

これは、中央周溝が、側端折れ曲がり部の折れ曲がりに対して補強リブとして作用して、この部分の剛性を高めているためと思われる。   This is presumably because the central circumferential groove acts as a reinforcing rib against the bending of the side edge bent portion, thereby increasing the rigidity of this portion.

このように、側端折れ曲がり部が、大きな曲率半径で折れ曲がっているので、押圧操作力を取り去ると、押圧時陥没部は、外層体の弾力により、両側端折れ曲がり部を含めた周端の折れ曲がり部を接近させる形態で、速やかに復元する。   In this way, since the side edge bent portion is bent with a large radius of curvature, when the pressing operation force is removed, the depressed portion when pressed is a bent portion of the peripheral end including the bent portions on both sides due to the elasticity of the outer layer body. Recover promptly in the form of approaching.

また、中央周溝を設けることにより、この中央周溝が胴部に対して補強リブとして機能して、胴部の剛性を高めることになるが、この剛性の高まりが大きい場合には、胴部のスクイズ性が低下するので、胴部の外層体の肉厚を減少させて、この胴部のスクイズ性の低下を防止する。   In addition, by providing the central circumferential groove, the central circumferential groove functions as a reinforcing rib with respect to the trunk portion and increases the rigidity of the trunk portion. Therefore, the thickness of the outer layer body of the body portion is reduced to prevent the squeeze property of the body portion from being lowered.

この場合、外層体の肉厚を減少させても、側端折れ曲がり部の折れ曲がり曲率半径は大きいままであるので、押圧時陥没部の速やかな復元変形を得ることができる。   In this case, even if the thickness of the outer layer body is reduced, the bending curvature radius of the side edge bent portion remains large, so that a quick restoration deformation of the depressed portion during pressing can be obtained.

本発明の別の構成は、容器本体の胴部の平面形状を略楕円形とし、この楕円形の長軸方向側の容器本体部分に、外層体と内層体とを剥離不能に接着固定する縦長帯状の接着帯を、容器本体の全高さ範囲に亘って設けた、ことにある外層体を、低密度ポリエチレン製とし、内層体を、エチレンービニルアルコール共重合体製とした、ことにある。   Another configuration of the present invention is that the planar shape of the body portion of the container body is substantially elliptical, and the outer layer body and the inner layer body are bonded and fixed to the container body part on the long axis direction side of the ellipse in a non-peelable manner. The present invention is to provide a belt-like adhesive band over the entire height range of the container body, in which the outer layer body is made of low density polyethylene and the inner layer body is made of an ethylene-vinyl alcohol copolymer.

容器本体の胴部を楕円筒状とし、かつ接着帯を設けたものにあっては、両接着帯の中間の胴部部分を押圧することにより、形成される押圧時陥没部の側端折れ曲がり部が、接着帯を設けた胴部部分の近くに位置することになり、このため機械的強度大きくなっている接着帯を設けた胴部部分が、側端折れ曲がり部に作用する変形力を安定して支え、これにより押圧時陥没部の弾力が、復元変形に有効に作用する。   In the case where the body of the container body has an elliptical cylindrical shape and is provided with an adhesive band, the side bent portion of the depression part when pressed is formed by pressing the intermediate body part between the two adhesive bands. However, it will be located near the body part where the adhesive band is provided, so the body part provided with the adhesive band that has increased mechanical strength stabilizes the deformation force acting on the side edge bent part. As a result, the elasticity of the depression when pressed acts effectively on the restoring deformation.

また、容器本体の胴部を把持しながら押圧する際、偏平となった短軸方向側の胴部部分の指先による把持が行い易く、またこの短軸方向側の胴部部分は大きな曲率半径であるので、押圧陥没変形させ易いと共に、陥没量の割には大きな押圧時陥没部を形成する。   In addition, when pressing while gripping the body portion of the container body, it is easy to hold the flat portion of the trunk portion on the short axis direction with the fingertips, and the trunk portion on the short axis direction side has a large radius of curvature. Therefore, it is easy to be deformed by pressing, and a large depressed portion is formed for the amount of depression.

また、本発明の別の構成は、外層体を、低密度ポリエチレン製とすると共に、内層体を、エチレンービニルアルコール共重合体製とし、容器本体の口筒部の外層体部分に、該外層体と内層体との間に外気を吸入する吸気孔を開設し、吐出口を形成すると共に、内容物の吐出は許すが、外気の侵入は阻止する吐出弁と、外層体と内層体との間への外気の侵入は許すが、侵入した外気の排出は阻止する吸気弁とを有するキャップを、前記口筒部に組付けた、ことにある。   Another configuration of the present invention is that the outer layer body is made of low-density polyethylene, the inner layer body is made of an ethylene-vinyl alcohol copolymer, and the outer layer body portion of the mouth tube portion of the container body is An air intake hole is formed between the body and the inner layer body to suck in outside air, and a discharge port is formed, and the discharge of the contents is allowed, but the intrusion of outside air is prevented, and the outer layer body and the inner layer body A cap having an intake valve that allows outside air to enter but prevents the outside air from being discharged is assembled to the mouth tube portion.

外層体を、低密度ポリエチレン製とし、内層体を、エチレンービニルアルコール共重合体製とし、容器本体の口筒部に、吐出弁と吸気弁とを有するキャップを設けたものにあっては、良好なスクイズ性と、滑らかで優れた触感の外層体を得ることができ、また酸素に対する高いガスバリア性を発揮する内層体を得ることができる。   The outer layer body is made of low density polyethylene, the inner layer body is made of an ethylene-vinyl alcohol copolymer, and the cap body having a discharge valve and an intake valve is provided on the mouth tube portion of the container body. An outer layer body having good squeezing properties and a smooth and excellent tactile sensation can be obtained, and an inner layer body exhibiting a high gas barrier property against oxygen can be obtained.

また、構造の複雑な弁機能部分をキャップに設けるので、弁機能部分により、ブロー成形品である容器本体の構造を複雑化することがない。   In addition, since the valve function portion having a complicated structure is provided in the cap, the valve function portion does not complicate the structure of the container body that is a blow molded product.

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。
本発明にあっては、容器本体の胴部の、押圧力が加えられる部分に中央周溝を設けただけであるので、その実施が容易である。
Since the present invention has the above-described configuration, the following effects can be obtained.
In the present invention, since the central circumferential groove is only provided in the portion of the body portion of the container main body to which the pressing force is applied, the implementation is easy.

また、内容物吐出後の押圧時陥没部が速やかに復元するので、内容物の反復吐出動作を、確実に安定して得ることができ、粘稠性内容物を収納したデラミボトル型容器の、好ましい動作状態を得ることができる。   In addition, since the depressed portion at the time of pressing after the content discharge quickly restores, the repeated discharge operation of the content can be reliably and stably obtained, and the delami bottle type container containing the viscous content is preferable. The operating state can be obtained.

さらに、中央周溝を設けることにより、外層体の肉厚を小さくすることが可能となり、その分、外層体を成形する合成樹脂材料の量を少なくすることができるので、樹脂材料の省資源化効果を得ることが可能である。   Furthermore, by providing the central circumferential groove, it becomes possible to reduce the thickness of the outer layer body, and accordingly, the amount of the synthetic resin material for molding the outer layer body can be reduced. An effect can be obtained.

容器本体の胴部を略楕円形とし、一対の接着帯を設けたものにあっては、粘稠性内容物の吐出操作が行い易いと共に、所望する内容物の突出が簡単となる。   In the case where the body portion of the container body is substantially oval and provided with a pair of adhesive bands, the viscous content can be easily discharged and the desired content can be easily projected.

外層体を、低密度ポリエチレン製とすると共に、内層体を、エチレンービニルアルコール共重合体製とし、吐出弁と吸気弁を有するキャップを、容器本体の口筒部に組付けたものにあっては、スクイズ性を利用したデラミボトル型容器として、好ましい使用状態を得ることができると共に、粘稠性内容物の高い品質保存性を得ることができ、デラミボトル型容器である容器本体の構造が複雑化することがなく、安定した外気の吸気と遮断とを得ることができる。   The outer layer body is made of low density polyethylene, the inner layer body is made of an ethylene-vinyl alcohol copolymer, and a cap having a discharge valve and an intake valve is assembled to the mouth tube portion of the container body. Can be used as a delami bottle type container utilizing squeeze properties, and can obtain a high quality preservability of viscous contents, and the structure of the container body that is a delami bottle type container is complicated. In this way, stable outside air intake and blocking can be obtained.

以下、本発明の実施形態を、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1は容器本体1の全体正面図、図2はその全体側面図で、下端を底部で閉鎖した胴部6の、上方にゆるやかに縮径した上部の上端に、段状の肩部を介して短円筒状の口筒部4を起立連設して構成されている。   FIG. 1 is an overall front view of the container body 1 and FIG. 2 is an overall side view of the body 6 with the lower end closed at the bottom. A short cylindrical mouth tube portion 4 is provided upright and continuously.

容器本体1は、スクイズ変形可能で復元自在な可撓性を有する低密度ポリエチレン製の外層体2と、この外層体2に剥離可能に積層され、粘蝶性内容物Mを収納し、内圧の減少により自在に減容変形する袋状に成形された、エチレンービニルアルコール共重合体製の内層体3とから、ブロー成形されて、デラミボトル型容器として構成されている。   The container body 1 is a squeeze-deformable and flexible low-density polyethylene outer layer body 2 and is laminated to the outer layer body 2 so as to be peeled off. It is blow molded from an inner layer body 3 made of an ethylene-vinyl alcohol copolymer, which is molded into a bag shape that can be freely reduced in volume by reduction, and is configured as a Delami bottle type container.

胴部6は、その全体が前後にやや偏平となった楕円筒形状をしていて、片手での把持が行い易い高さ位置には、中央周溝7が周設されており、この中央周溝7は、溝底壁の上下に拡幅傾斜した溝側壁を有する構造となっている。   The body portion 6 has an elliptical cylindrical shape that is slightly flattened back and forth, and a central circumferential groove 7 is provided at a height position where gripping with one hand is easy. The groove 7 has a structure having groove side walls that are widened and inclined above and below the groove bottom wall.

図示実施形態例の場合、中央周溝7は、溝底壁の幅が3mm、開放溝幅が7mm,溝深さが2mmとなっていて、適当な補強力を発揮できると共に、指先が軽く引っ掛った状態で、押圧できるようにしている。   In the case of the illustrated embodiment, the central circumferential groove 7 has a groove bottom wall width of 3 mm, an open groove width of 7 mm, and a groove depth of 2 mm. It is possible to press in the hanging state.

口筒部4は、外周面に螺条を刻設していると共に、螺条の下位の前後に対向した箇所の外層体2部分に、外気を外層体2と内層体3との間に吸気するための吸気孔5を開設しており、外周面下端部分を、螺条の外径よりも大きい外径の膨出部分としている。   The mouth tube portion 4 has a thread formed on the outer peripheral surface thereof, and outside air is sucked between the outer layer body 2 and the inner layer body 3 into a portion of the outer layer body 2 that is opposed to the front and rear of the lower portion of the thread. The lower end portion of the outer peripheral surface is a bulging portion having an outer diameter larger than the outer diameter of the thread.

また、容器本体1の両側部分、すなわち胴部6の楕円形の長軸方向側の部分には、容器本体1の全高さ範囲に亘って、外層体2と内層体3とを接着固定する、縦長帯状の接着帯6a(図2、図3参照)が設けられており、これにより萎み変形する内層体3は前後に区画されることになると共に、一対の吸気孔5は、この二つに区画された内層体3部分のそれぞれに一対一に対向することになる。   Further, the outer layer body 2 and the inner layer body 3 are bonded and fixed to both side portions of the container body 1, that is, the elliptical long axis direction portion of the body portion 6 over the entire height range of the container body 1. A longitudinal band-like adhesive band 6a (see FIGS. 2 and 3) is provided, whereby the inner layer body 3 which is deformed by warping is partitioned forward and backward, and the pair of air intake holes 5 has two of them. Each of the inner layer body 3 sections that are partitioned in a one-to-one relationship.

中央周溝7が位置する胴部6の前後の中央部を指先で把持して押圧すると、胴部6の中央部は中央周溝7と一緒に、図3に示すように陥没し、この陥没により粘稠性内容物Mが吐出されるが、この際、押圧時陥没部aは、その周端部の一部である周方向側の側端折れ曲がり部bは、図9に示す、中央周溝7がない場合に比べて、大きな曲率半径で折れ曲がることになる。   When the front and rear central portions of the body portion 6 where the central circumferential groove 7 is located are gripped and pressed with fingertips, the central portion of the body portion 6 is depressed together with the central circumferential groove 7 as shown in FIG. The viscous contents M are discharged by the above-mentioned method. At this time, the depressed portion a is a part of the peripheral end portion, and the side-end bent portion b which is a part of the peripheral end portion is a central periphery shown in FIG. As compared with the case where there is no groove 7, it bends with a large radius of curvature.

このように、押圧時陥没部aの陥没変形は、図9に示すように、反転変形ではなく、中央周溝7により単純な湾曲変形となり、これにより速やかに確実に行われることになる。   Thus, as shown in FIG. 9, the depression deformation of the depression portion a at the time of pressing is not a reversal deformation but a simple curved deformation by the central circumferential groove 7, and this is quickly and reliably performed.

容器本体1の口筒部4に組付けられたキャップ8(図5および図7参照)は、吐出口12を形成するキャップ本体9と、このキャップ本体9にヒンジ17により結合されて、吐出口12を開閉する蓋体16とから構成されている。   A cap 8 (see FIG. 5 and FIG. 7) assembled to the mouth tube portion 4 of the container body 1 is coupled to a cap body 9 forming the discharge port 12 and a hinge 17 to the cap body 9. And a lid 16 that opens and closes 12.

キャップ本体9は、口筒部4に密に螺合組付きする組付き筒10と、この組付き筒10の上端に位置した頂壁部11とから構成され、この頂壁部11は、中央に吐出口12を、また周端部に吸気口13を開設すると共に、吐出口12に下方から対向した箇所に、粘稠性内容物Mの吐出は許すが、外気の侵入は阻止する吐出弁14を、また吸気口13に下方から対向した箇所に、外気の吸入は許すが、吸入された外気の排出は許さない吸気弁15を設けている。   The cap body 9 is composed of an assembled cylinder 10 that is tightly screwed to the mouth tube section 4 and a top wall section 11 that is positioned at the upper end of the assembled cylinder 10. The discharge port 12 and the intake port 13 at the peripheral end, and the discharge valve that allows the viscous content M to be discharged to the location facing the discharge port 12 from below, but prevents the outside air from entering. 14 and a portion facing the intake port 13 from below is provided with an intake valve 15 that allows the intake of outside air but does not allow the intake air to be discharged.

組付き筒19の下端開口部分は、口筒部4の下端部分である膨出部分に密に外嵌し、これにより吸気孔5に対する外気の侵入は、キャップ本体9の吸気口13以外からは不可能にしている。   The lower end opening portion of the assembled cylinder 19 is closely fitted to the bulging portion, which is the lower end portion of the mouth tube portion 4, so that intrusion of outside air into the intake hole 5 is from other than the intake port 13 of the cap body 9. Making it impossible.

それゆえ、図4に示すように、吐出口12を開放した状態で、容器本体1を倒立状に傾けて胴部6の中央部を把持して押圧すると、この押圧に伴う内圧の上昇に従って、吐出弁14が開放(図5参照)されて、粘稠性内容物Mが吐出口12から吐出される。   Therefore, as shown in FIG. 4, when the container body 1 is tilted in an inverted state with the discharge port 12 opened, the center portion of the body portion 6 is gripped and pressed, according to the increase in internal pressure accompanying this pressing, The discharge valve 14 is opened (see FIG. 5), and the viscous content M is discharged from the discharge port 12.

この際、外層体2と内層体3の間に形成される空間cの圧力は、大気圧よりも高くなるので、吸気弁15は「閉」状態となって、空間c内の外気の排出を阻止する。   At this time, since the pressure in the space c formed between the outer layer body 2 and the inner layer body 3 is higher than the atmospheric pressure, the intake valve 15 is in a “closed” state and discharges the outside air in the space c. Stop.

粘稠性内容物Mの所望量の吐出が終了して、胴部6に対する押圧力の作用を解除すると、押圧時陥没部aの外層体2部分の復元により、吐出弁14が「閉」状態となると共に、吸気弁15が「開」状態となって、空間cに外気を吸入(図7参照)し、次の吐出動作に備える。   When the discharge of the desired amount of the viscous content M is finished and the action of the pressing force on the body portion 6 is released, the discharge valve 14 is in the “closed” state by the restoration of the outer layer body 2 portion of the depressed portion a at the time of pressing. At the same time, the intake valve 15 is in the “open” state, sucking outside air into the space c (see FIG. 7), and preparing for the next discharge operation.

以上説明したように、本発明のスクイズ性を利用したデラミボトル型容器は、スクイズ性を低下させることなく、スクイズ動作に伴う陥没変形の復元を速やかに達成することができるので、デラミボトル型容器に限らず、スクイズ動作を利用する容器に、幅広く利用できることが期待できる。   As described above, the delamination bottle type container using the squeeze property of the present invention can quickly recover the depressed deformation accompanying the squeeze operation without reducing the squeeze property. First, it can be expected that the container can be widely used for a squeeze operation container.
