Abstract

PROBLEM TO BE SOLVED: To provide a small capacity container for viscous substance capable of always performing discharge of viscous contents quickly, even in the case where the container is held in an inverted state or a state close to an inverted state.SOLUTION: In a small capacity container for viscous substance whose content quantity is equal to or less than 300 ml, as a body part inner surface of the container has an asymmetrical-shaped irregular side cross section part, on the inner surface of the body part 1, a portion exists in which a difference occurs in falling speed of contents. Therefore, as falling of contents 10 is not even, an air layer 13 between the contents 10 and a bottom part 5 escapes easily from a side on which a thickness of the contents 10 is thin (side 1b on which falling speed is slow). Thus, inconvenience of discharge difficulty in which the contents 10 stay in the container can be effectively avoided.SELECTED DRAWING: Figure 1

Description

本発明は、内容量が３００ｍｌ以下の粘稠物質用小容量容器に関するものであり、特に高粘性の流動体が収容される粘稠物質用小容量容器に関する。   The present invention relates to a small-capacity container for viscous substances having an internal volume of 300 ml or less, and particularly to a small-capacity container for viscous substances in which a highly viscous fluid is accommodated.

液状内容物が収容される容器では、容器の材質を問わず、内容物に対する排出性が要求される。水のように粘性の低い液体を収容する場合では、このような排出性はほとんど問題とならないが、例えば、マヨネーズやケチャップのように粘度の高い粘稠な物質では、プラスチック製容器であろうがガラス製容器であろうが、内容物が速やかに排出され、しかも、容器内に残存することなく、最後まで使い切ることができるようにすることが求められている。   In a container in which a liquid content is stored, dischargeability to the content is required regardless of the material of the container. In the case of containing a low viscosity liquid such as water, such discharge is hardly a problem. For example, in a viscous material such as mayonnaise or ketchup, it may be a plastic container. Whether it is a glass container, there is a demand for the contents to be quickly discharged and used up to the end without remaining in the container.

ところで、上記のような排出性に関しては、容器等の成形体の表面に油膜を形成するという手段が種々提案されている（例えば特許文献１，２）。このような油膜の形成により、粘稠な物質に対する滑り性が高められ、その排出性が向上するというものである。   By the way, regarding the above-described dischargeability, various means for forming an oil film on the surface of a molded body such as a container have been proposed (for example, Patent Documents 1 and 2). By forming such an oil film, the slipperiness with respect to a viscous substance is improved, and the discharge property is improved.

しかしながら、小容量の容器に特に粘稠な内容物が収容されているときには、内容物の排出が困難になることがあった。即ち、内容物排出のために、容器を倒立状態に保持したときに、内容物が取り出し口に到達する前に、容器内にとどまった状態となってしまうのである。   However, when particularly viscous contents are stored in a small-capacity container, it may be difficult to discharge the contents. That is, when the container is held in an inverted state for discharging the contents, the contents remain in the container before reaching the outlet.

ＷＯ２０１２／１０００９９WO2012 / 100099 ＷＯ２０１３／０２２４６７WO2013 / 022467

従って、本発明の目的は、倒立或いは倒立に近い状態に保持した場合においても、常に、粘稠な内容物の排出を速やかに行うことが可能な粘稠物質用小容量容器を提供することにある。   Accordingly, an object of the present invention is to provide a small-capacity container for viscous substances that can always quickly discharge viscous contents even when held in an inverted or near-inverted state. is there.

本発明によれば、内容量が３００ｍｌ以下の粘稠物質用小容量容器において、該容器の胴部内面は、非対称形状の異形側断面部を有していることを特徴とする粘稠物質用小容量容器が提供される。   According to the present invention, in a small volume container for a viscous material having an internal volume of 300 ml or less, the inner surface of the body portion of the container has an asymmetrical irregular side cross-sectional portion. A small volume container is provided.

本発明の粘稠物質用小容量容器は、
（１）粘度（２５℃）が８Ｐａ・ｓ以上の粘稠なペースト状内容物の収容に使用されること、
（２）該内容物が食品、医薬品、歯磨き粉であること、
が好適である。 The small-capacity container for viscous substances of the present invention is
(1) It is used for accommodating a viscous paste-like content having a viscosity (25 ° C.) of 8 Pa · s or more,
(2) The content is food, medicine, toothpaste,
Is preferred.

本発明の粘稠物質用小容量容器は、その胴部の側断面において、その内面が非対称の異形側断面となる部分を有していることが重要な特徴である。即ち、このような異形側断面部が胴部に形成されている粘稠物質用容器では、これを倒立して内容物を排出したとき、胴部から速やかに排出される部分と排出に時間がかかる部分とが存在する。このため、このような速度差によって容器の底部に内容物によって閉じ込められた空気が容易に排出されることとなり、この結果として、内容物が粘稠なペースト状のもの、例えば粘度（２５℃）が８Ｐａ・ｓ以上の粘稠なペースト状物であったとしても、容器内にとどまることなく、その排出を常に容易に行うことが可能となる。   An important feature of the small-capacity container for viscous materials of the present invention is that the inner surface has a portion having an asymmetrical profile in the side section of the body. That is, in such a viscous material container having a deformed side cross-section formed in the body part, when the contents are discharged by inverting it, the portion quickly discharged from the body part and the time for discharge are discharged. Such a part exists. For this reason, the air trapped by the contents at the bottom of the container is easily discharged by such a speed difference, and as a result, the contents are viscous paste-like, for example, viscosity (25 ° C.) Even if it is a viscous paste-like material of 8 Pa · s or more, it can always be easily discharged without staying in the container.

図１を参照して、本発明の粘稠物質用小容量容器は、倒立状態で示されており、中空筒状の胴部１を備えており、胴部１の一方側端部には、内容物の排出口となる首部３が形成されており、他方側端部は、底部５によって閉じられている。
また、容器の形態によっても異なるが、首部３の外面には、キャップにて封止するための螺子７が形成されている。 With reference to FIG. 1, the small-capacity container for a viscous material of the present invention is shown in an inverted state, and includes a hollow cylindrical body portion 1. A neck 3 serving as a discharge port for contents is formed, and the other end is closed by a bottom 5.
Moreover, although it changes with forms of a container, the screw | thread 7 for sealing with a cap is formed in the outer surface of the neck part 3. FIG.

このような本発明の粘稠物質用小容量容器において、その内容量は３００ｍｌ以下、特に１５０ｍｌ以下である。即ち、このような小容量のものは、軽量であることから、図１に示されているように、容器を倒立或いは倒立に近い状態に保持して内容物の排出を行うことがあり、このときに内容物の排出が困難となる事態を生じ易いが、大容量容器では、重く、しかも把手が付いている場合が多いことなどから、容器を倒立或いはそれに近い状態に保持することはなく、内容物の排出性が問題となることはないからである。   In such a small-capacity container for viscous materials of the present invention, the inner volume is 300 ml or less, particularly 150 ml or less. That is, since such a small capacity is lightweight, as shown in FIG. 1, the container may be held in an inverted or near-inverted state and the contents may be discharged. Occasionally it becomes difficult to discharge the contents, but in large-capacity containers, it is heavy and often has a handle, so the container is not inverted or held close to it, This is because the discharge of contents does not become a problem.

本発明において、特に図１（ａ）に示されているように、胴部１の内面に、異形側断面部分が形成されていることが重要である。即ち、このような異形断面部では、内容物の落下に速度差が生じる。例えば、図１（ａ）の例では、胴部１の一方側の内面１ａは、ストレートに近い形状の面となっており、他方側の内面１ｂは、大きな曲線部分を含んでいる。この結果、内容物１０は、内面１ａ側において落下速度が速く、内面１ｂ側での落下速度は遅い。   In the present invention, as shown in FIG. 1 (a) in particular, it is important that a deformed side cross-sectional portion is formed on the inner surface of the body portion 1. That is, in such a modified cross-section, a speed difference occurs in the content drop. For example, in the example of FIG. 1A, the inner surface 1a on one side of the body portion 1 is a surface having a shape close to a straight, and the inner surface 1b on the other side includes a large curved portion. As a result, the content 10 has a high drop speed on the inner surface 1a side and a lower drop speed on the inner surface 1b side.

一方、図２は、従来公知の小容量容器の形態を倒立状態で示す図であるが、この図２から理解されるように、側断面形状は、容器の長手方向軸線に対して対称な線対称形状であり、異形断面部分を有していない。
即ち、このような容器では、これを図２（ａ）に示されているように倒立状態に保持して内容物１０を排出すると、内容物１０が胴部１の内面に沿って均等に落下するため、首部３の開口部に到達する前に、容器内にとどまった状態に保持されてしまう。このような状態では、内容物１０と底部５との間に空気層１３が閉じ込められてしまい、空気層１３の圧よりも大気圧の方が大きいため、内容物１０が容器内にとどまったままの状態となり、その排出が困難となってしまう。 On the other hand, FIG. 2 is a diagram showing a conventionally known small-capacity container in an inverted state, but as can be understood from FIG. 2, the side cross-sectional shape is a line symmetrical with respect to the longitudinal axis of the container. It is symmetrical and does not have an irregular cross-section.
That is, in such a container, as shown in FIG. 2A, when the contents 10 are discharged while being held in an inverted state, the contents 10 are evenly dropped along the inner surface of the body 1. Therefore, before reaching the opening of the neck 3, the container stays in the container. In such a state, the air layer 13 is confined between the contents 10 and the bottom 5, and the atmospheric pressure is larger than the pressure of the air layer 13, so the contents 10 remain in the container. It becomes difficult to discharge.

しかるに、本発明によれば、図１（ａ）に示されているように異形断面部が形成され、胴部１の内面には、内容物の落下速度に差が生じる部位が存在している。従って、内容物１０の落下が均等でないため、内容物１０と底部５との間の空気層１３は、例えば、内容物１０の厚みが薄い側（落下速度が遅い１ｂ側）から容易に抜けることとなり、従って、容器内に内容物１０がとどまって排出困難となるという不都合が有効に回避される。   However, according to the present invention, as shown in FIG. 1 (a), a deformed cross-section is formed, and there is a portion on the inner surface of the body 1 where a difference in the falling speed of contents exists. . Therefore, since the fall of the content 10 is not uniform, the air layer 13 between the content 10 and the bottom part 5 can be easily removed from the side where the thickness of the content 10 is thin (the 1b side where the fall speed is slow), for example. Therefore, the inconvenience that the contents 10 stay in the container and is difficult to be discharged is effectively avoided.

本発明において、上記のような異形断面部の形態は、内容物１０の落下速度に差が生じるような形態であれば特に制限されず、どのような形態であってもよいが、通常、容器の軸方向に対して段差が有するような形態は避けることが好ましい。この段差部分に内容物１０の一部がとどまって排出され難くなってしまうことがあるからである。
一般的には、内容物１０の落下速度が速い側１ａは、直線もしく直線に近い形態、或いは曲線の中にクロソイド曲線のような曲線部を設け、他方の内容物１０の落下速度が遅い側１ｂは、大きな曲線部、例えばサイクロイド曲線を含むようにすることにより、異形断面部を形成すればよい。 In the present invention, the shape of the deformed cross section as described above is not particularly limited as long as it causes a difference in the falling speed of the contents 10, and may be any shape. It is preferable to avoid a form having a step with respect to the axial direction. This is because a part of the content 10 stays at the stepped portion and it is difficult to be discharged.
Generally, the side 1a on which the falling speed of the content 10 is fast is a straight line or a shape close to a straight line, or a curved portion such as a clothoid curve is provided in the curve, and the falling speed of the other content 10 is slow. The side 1b may be formed with a deformed cross section by including a large curved portion, for example, a cycloid curve.

また、図１（ａ）に示されているような形態、即ち、内容物１０の落下速度が速い側１ａと内容物１０の落下速度が遅い側１ｂとが互いに対向する位置に存在する形態に限定されず、１ａと１ｂとが近い位置に存在するような形態であってもよい。   Further, in the form as shown in FIG. 1 (a), that is, the side 1a on which the falling speed of the contents 10 is fast and the side 1b on which the falling speed of the contents 10 is slow are located at positions facing each other. It is not limited, The form that 1a and 1b exist in the near position may be sufficient.

上述した異形断面部を有する本発明の粘稠物質用小容量容器は、原理的には、異形断面部が形成されているという条件を満足する限りにおいて、プラスチック、ガラス、金属等の任意の材料で形成されていてよいが、実際は、成形上の観点からプラスチック製であることが望ましい。
また、容器の形態も特に制限はされないが、好適には、中空成形により形成され、内容物を排出する開口が大きくないボトルやチューブなどの形態を有していることが最も好適である。即ち、内容物を排出する開口が広口容器やカップなどでは、内容物１０の排出性に問題は生じないからである。
例えば、図１の例では、ブロー成形容器の形態が示されているが、チューブ容器であってもよい。 In principle, the small-capacity container for a viscous substance of the present invention having the above-mentioned irregular cross-section portion can be any material such as plastic, glass, metal, etc. as long as the condition that the irregular cross-section portion is formed is satisfied. In practice, it is desirable that the plastic is made from the viewpoint of molding.
Also, the form of the container is not particularly limited, but it is most preferable that the container has a form such as a bottle or tube which is formed by hollow molding and does not have a large opening for discharging the contents. That is, when the opening for discharging the contents is a wide-mouthed container, a cup, or the like, there is no problem with the discharge of the contents 10.
For example, in the example of FIG. 1, the form of a blow molded container is shown, but a tube container may be used.

さらに、本発明において、容器に収容する内容物としては、粘性の高い粘稠なペースト状物、具体的には、粘度（２５℃）が８Ｐａ・ｓ以上の粘稠なペースト状内容物の収容に使用されることが好適である。このようなペースト状内容物には、ゲルのような形態を有するものが多く、各種食品類に限らず、医薬品、歯磨き粉などがある。   Furthermore, in the present invention, the contents stored in the container include a viscous paste-like material having a high viscosity, specifically, a viscous paste-like content having a viscosity (25 ° C.) of 8 Pa · s or more. It is suitable to be used for. Many of such paste-like contents have a gel-like form, and are not limited to various foods, but include pharmaceuticals and toothpastes.

本発明の粘稠物質用小容量容器は、倒立による内容物の排出性に優れており、これを利用して各種の用途に広く使用される。   The small-capacity container for viscous substances of the present invention is excellent in discharging contents by inversion, and is widely used for various applications using this.
