Description

本発明は、吐出器付き薄肉容器に関する。   The present invention relates to a thin container with a dispenser.

例えば、シャンプーやリンス、化粧料等を充填する容器にあっては、充填した内容液を簡単に注出させるべく、容器の口部に吐出器を取り付けた吐出器付き容器が知られている(特許文献1)。   For example, in a container filled with shampoo, rinse, cosmetics, etc., a container with a dispenser in which a dispenser is attached to the mouth of the container is known in order to easily dispense the filled content liquid ( Patent Document 1).

特開2008−189317JP2008-189317

ところで、近年では環境への負荷を低減するとともにコストを下げるために、容器に用いられる樹脂量の削減が求められている。このため、容器の肉厚を薄くする検討がなされているが、そのためにはノズルヘッドを押下した場合の力にも耐えられることが必要である。例えば、ノズルヘッドの押下力は、吐出量が3gのディスペンサーでは30N以上となる。しかし、特許文献1の容器で用いられるような従来の材質では、胴部の肉厚が1mmを下回るとノズルヘッドの押下力によって容器が座屈することがあり、スムーズな注出が困難となっていた。   By the way, in recent years, in order to reduce the burden on the environment and reduce the cost, it is required to reduce the amount of resin used in the container. For this reason, studies have been made to reduce the wall thickness of the container. To this end, it is necessary to withstand the force when the nozzle head is pressed. For example, the pressing force of the nozzle head is 30 N or more for a dispenser with a discharge amount of 3 g. However, in the conventional material used in the container of Patent Document 1, if the thickness of the body portion is less than 1 mm, the container may buckle due to the pressing force of the nozzle head, and smooth dispensing is difficult. It was.

本発明の目的は、肉厚が薄くてもノズルヘッドの押下力によって容器が座屈することがなく、内容液をスムーズに注出することができ、薄肉容器の自立状態を維持することができる吐出器付き薄肉容器を提供することである。   An object of the present invention is to discharge the contents liquid smoothly without being buckled by the pressing force of the nozzle head even when the wall thickness is thin, and the thin liquid container can be maintained in an independent state. It is to provide a thin container with a vessel.

The second leg member 70 includes at least a second leg cylinder 72 and a plurality of tilting members 78, and prevents the thin container body from buckling in cooperation with the first leg member 52. Make sure.
The second leg cylinder 72 surrounds the first leg cylinder 54 with an annular gap a. The annular gap a allows the vent hole 21 of the cylinder 18 to communicate with the bottom of the thin container body 2. In the illustrated example, the upper end portion of the second leg cylinder 72 is the enlarged diameter cylindrical portion 73, and the locking flange 74 protrudes outward from the upper end of the enlarged diameter cylindrical portion 73. As shown in FIG. 1, the enlarged diameter cylindrical portion 73 is fitted on the inner surface of the mouth and neck portion 8, and the locking flange 74 is brought into contact with the upper surface of the mouth and neck portion 8. 8 can be attached firmly. Then, the flange portion 20, the packing P, and the locking flange 74 are sandwiched between the inward flange 16 of the mounting member 12 and the upper surface of the mouth neck portion 8. But it is not necessary to form an enlarged diameter cylinder part.

上記複数の傾動材78は、上記第2脚筒72の下端と連結材60の先端部との間に設けられており、上記薄肉容器体の座屈を防止するのに十分な剛性を有する。図示の傾動材78は帯板状に形成されており、その下部に係合孔80が穿設され、この係合孔80に上記係合突子64を嵌着して傾動材78の下部と連結材60の先端部を重ね合わせた状態で固定している。また傾動材78の上端は第3ヒンジ部76を介して第2脚筒72の下端に連結されている。   The plurality of tilting members 78 are provided between the lower end of the second leg cylinder 72 and the distal end portion of the connecting member 60, and have sufficient rigidity to prevent buckling of the thin container body. The illustrated tilting member 78 is formed in the shape of a band plate, and an engagement hole 80 is formed in the lower portion thereof. The engaging protrusion 64 is fitted into the engagement hole 80 to form a lower portion of the tilting member 78. The front end portion of the connecting member 60 is fixed in an overlapped state. The upper end of the tilting member 78 is connected to the lower end of the second leg cylinder 72 via the third hinge portion 76.

傾動材78及び連結材60の長さは、図1の状態において、連結材60の先端部60bが傾動材78の下部に追従して傾動するとともに、傾動材78の下端である当接端部84Aが薄肉容器体2の隅部付近に当接するように設けるとよい。図1の状態で連結材本体60aは略水平であり、連結材本体60aと薄肉容器体2の底部との間には間隙gが形成されている。
各傾動材78の巾は、図示例において、図3に示すように連結材60の巾より大きくしている。
In the state of FIG. 1, the tilting member 78 and the connecting member 60 have the lengths of the contact end portion that is the lower end of the tilting member 78 while the front end portion 60 b of the connecting member 60 tilts following the lower portion of the tilting member 78. 84A may be provided so as to be in contact with the vicinity of the corner of the thin container body 2. In the state of FIG. 1, the connecting material main body 60 a is substantially horizontal, and a gap g is formed between the connecting material main body 60 a and the bottom of the thin container body 2.
In the illustrated example, the width of each tilting member 78 is larger than the width of the connecting member 60 as shown in FIG.

上記構成において、上記連結材60は第1ヒンジ部58を中心として、また傾動材78は第2ヒンジ部62を中心として、それぞれ下向きに回動可能であり、この状態では、自立用治具50は、図2に示す如く、細身の形態となる。
この形態で吐出器10の下部及び自立用治具50を薄肉容器体2の口頸部8から内部へ挿入することができる。第2脚部材70の下端側の当接端部84Aが薄肉容器体2の底部4に当接すると、図4に矢示する如く、当接端部84Aが底部4上を外側にスライドする。
これにより自立用治具50の下半部は、図1に示すように拡開する。
次に装着部材12の装着筒部14を口頸部8の外面に嵌合させることにより、上記当接端部84Aは、薄肉容器体2の底部4に位置する。
この状態において、傾動材78は傾斜姿勢で第2脚筒72を支えており、かつ第2脚筒72の上端の係止フランジ74は鍔部20及びパッキンPとともに口頸部8の上面と装着部材12の内向きフランジ16との間で挟持されているため、薄肉容器体2の自立を確実なものとすることができる。
具体的には、第2脚部材の当接端部が容器底部に当接することで支持力を発揮し、座屈に耐える構造となっている。すなわち、少なくとも三点で支持することで座屈強度がアップする。これにより、薄肉容器が潰れず、スムーズな注出が可能となる。基本的には当接端部の三点で座屈に耐える構造であるが、より大きな荷重が作用したときには、補助的に、第1脚部材の各下端部も押圧時に底部に接触するので、さらに座屈防止の効果が高まる。
薄肉容器体2内の液体を使い切ったときには、上記装着筒部14を口頸部8の外面から外して吐出器10及び自立用治具50を引き上げると、連結材60及び傾動材78はそれぞれの自重により下向きに回動し、図2に示す細身の形態となる。
この形態で口頸部8から吐出器10及び自立用治具50を取り出し、液体が充填された別の薄肉容器体2に装着することができる。
In the above-described configuration, the connecting member 60 is pivotable downward about the first hinge portion 58 and the tilting member 78 is pivotable downward about the second hinge portion 62. In this state, the self-standing jig 50 As shown in FIG.
In this form, the lower part of the discharge device 10 and the self-standing jig 50 can be inserted into the thin container body 2 from the mouth and neck portion 8 into the inside. When the contact end portion 84A on the lower end side of the second leg member 70 contacts the bottom portion 4 of the thin container body 2, the contact end portion 84A slides outward on the bottom portion 4 as shown in FIG.
As a result, the lower half of the self-standing jig 50 is expanded as shown in FIG.
Next, the contact end portion 84 </ b> A is positioned on the bottom portion 4 of the thin container body 2 by fitting the mounting cylinder portion 14 of the mounting member 12 to the outer surface of the mouth / neck portion 8.
In this state, the tilting member 78 supports the second leg cylinder 72 in an inclined posture, and the locking flange 74 at the upper end of the second leg cylinder 72 is attached to the upper surface of the mouth-and-neck part 8 together with the flange part 20 and the packing P. Since it is sandwiched between the inward flange 16 of the member 12, the thin container body 2 can be surely self-supported.
Specifically, the abutting end of the second leg member abuts against the bottom of the container to exert a supporting force and to withstand buckling. That is, the buckling strength is increased by supporting at least three points. Thereby, a thin container is not crushed and smooth pouring becomes possible. Basically it is a structure that can withstand buckling at three points of the contact end, but when a larger load is applied, each lower end of the first leg member also comes into contact with the bottom when pressed, Furthermore, the effect of preventing buckling is enhanced.
When the liquid in the thin-walled container body 2 is used up, the connecting member 60 and the tilting member 78 are removed by removing the mounting cylinder 14 from the outer surface of the mouth-and-neck portion 8 and pulling up the discharge device 10 and the self-standing jig 50. It turns downward due to its own weight, and becomes a slender form shown in FIG.
In this form, the dispenser 10 and the self-supporting jig 50 can be taken out from the mouth / neck portion 8 and mounted on another thin container body 2 filled with liquid.
