Description

本発明は、合成樹脂製の薄肉容器に関するものであり、注出頚部の潰れを回避して注出作業の改善を図ろうとするものである。   The present invention relates to a thin-walled container made of synthetic resin, and is intended to improve the pouring operation by avoiding crushing of the pouring neck.

シャンプーやリンス、液体石鹸、化粧料等を入れる容器の分野では、資源の有効活用、ゴミの減量化を図る観点から、とくに詰め替え容器として使用される容器としては、合成樹脂をブロー成形することによって所望の形状に形成した薄肉の容器が提案されている（例えば、特許文献１参照）。
特開２００５−０６７６８０号公報 In the field of containers for shampoos, rinses, liquid soaps, cosmetics, etc., from the viewpoint of effective use of resources and reduction of waste, especially as containers used as refill containers, blow molding synthetic resin A thin-walled container formed in a desired shape has been proposed (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2005-066760

従来、この種の容器は、詰め替え容器として用いられるのが普通であり、注出部に予め設けられたノッチや破断予定線に沿って栓体を切断、分離することで容器を開封することを通例としているところ、該注出部も薄肉になっていることからその部位には腰がなく、内容物を詰め替えるに際しては注ぎにくい不具合があった。   Conventionally, this type of container is usually used as a refill container, and the container is opened by cutting and separating the plug body along a notch or a planned break line provided in advance in the pouring part. As usual, since the pouring part is also thin, there is no waist in the part, and there is a problem that it is difficult to pour when refilling the contents.

本発明の課題は、内容物が注ぎ易い薄肉容器を提案するところにある。   The subject of this invention exists in the place which proposes the thin container in which the contents are easy to pour.

本発明は、薄肉の胴体を備えた合成樹脂製の薄肉容器であって、
前記胴体の頂部に、破断予定線に沿う引きちぎりよって開封可能な密閉栓を備えた注出頚部を設け、該注出頚部に、内壁の対向壁相互にわたってつながり、注出経路を複数に区分する縦リブ状の障壁を設けたことを特徴とする薄肉容器である。 The present invention is a thin container made of synthetic resin provided with a thin body,
The top of the body is provided with a pouring neck having a sealing plug that can be opened by tearing along the planned breaking line, and the pouring neck is connected across the opposing walls of the inner wall to divide the pouring path into a plurality of portions. A thin-walled container provided with a vertical rib-shaped barrier.

上記の構成になる薄肉容器において、少なくとも両サイドに位置する障壁は、注出頚部の基端から先端に向けて注出経路の幅を漸次に拡大する湾曲壁とするのが好ましい。   In the thin container having the above-described configuration, it is preferable that the barriers positioned at least on both sides are curved walls that gradually increase the width of the extraction path from the proximal end to the distal end of the extraction neck.

注出頚部の内壁に縦リブ状の障壁を設けることで該注出頚部の剛性が高まるため内容物が注ぎ易くなる。また、障壁により注出経路はスリットが形成された状態になるので、内容物をシャワー状の形態で排出することができる。   By providing a vertical rib-like barrier on the inner wall of the dispensing neck, the rigidity of the dispensing neck is increased, making it easier to pour the contents. Moreover, since the dispensing path is in a state where slits are formed by the barrier, the contents can be discharged in a shower-like form.

以下、図面を参照して本発明をより具体的に説明する。
図１は本発明に従う合成樹脂製の薄肉容器の実施の形態を示した図であり、図２は密閉栓を引きちぎって容器を開封した状態の要部の外観斜視図である。 Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a view showing an embodiment of a thin-walled container made of a synthetic resin according to the present invention, and FIG. 2 is an external perspective view of a main part in a state in which the container is opened by tearing off a sealing stopper.

図における１は容器の胴体である。この胴体１は薄肉になっており、内容物の充填量が減るにしたがって減容可能になっている。   In the figure, 1 is the body of the container. The body 1 is thin and can be reduced in volume as the filling amount of the contents decreases.

また、２は胴体１の頂部に設けられた薄肉の注出頚部である。注出頚部２は容器の胴体１と一体的に成形され、胴体１に直接つながる筒状の本体部分２ａと、破断予定線Ｌを介して引きちぎり可能につながる密閉栓２ｂから構成されている。   Reference numeral 2 denotes a thin-out pouring neck provided on the top of the body 1. The dispensing neck portion 2 is formed integrally with the body 1 of the container, and includes a cylindrical main body portion 2a that is directly connected to the body 1 and a sealing plug 2b that can be torn off via a planned fracture line L.

３は密閉栓２ｂの天面に設けられた溶着部である。この溶着部３は、内容物を容器の胴部１に充填する充填口を形成するものであり、内容物の充填後に熱や接着剤を利用して密着される。この溶着部３は、薄い板状部材になっていて、密閉栓２ｂを引きちぎる際の摘みとして使用することができる。   Reference numeral 3 denotes a welded portion provided on the top surface of the sealing plug 2b. This welding part 3 forms the filling port which fills the trunk | drum 1 of a container with the contents, and is closely_contact | adhered using a heat | fever or an adhesive agent after filling of the contents. The welded portion 3 is a thin plate-like member, and can be used as a knob when the sealing plug 2b is torn off.

４は注出頚部２の内壁の対向壁相互間にわたって設けられた縦リブ状の障壁である。この障壁４は間隔をおいて複数枚設けられており、この障壁４によって注出経路をスリット状の開口としている。   Reference numeral 4 denotes a vertical rib-like barrier provided between the opposing walls of the inner wall of the dispensing neck 2. A plurality of the barriers 4 are provided at intervals, and the barrier 4 makes the extraction path a slit-like opening.

注出頚部２の経路内に設けられた障壁４は該注出頚部２の補強材として機能するため注出頚部２そのものの剛性を高めることとなり簡単に変形するのが避けられ内容物を注出する際に注ぎ易くなる。   The barrier 4 provided in the path of the dispensing neck 2 functions as a reinforcing material for the dispensing neck 2 so that the rigidity of the dispensing neck 2 itself is increased, so that it is prevented from being easily deformed and the contents are dispensed. It becomes easy to pour it.

また、内容物は障壁４の間に形成される隙間を通して注出されるためにシャワー状となって注出される。   Further, since the contents are poured out through a gap formed between the barriers 4, they are poured out in a shower form.

図３は注出頚部２の本体部分２の断面を示した図である。障壁４のうち、少なくとも両サイドに位置する障壁を注出頚部２の基端から先端に向け内壁側に湾曲させた湾曲壁とすることにより注出経路の幅が漸次に拡大されることとなり、注出にかかる内容物は放射状（扇形状）に排出することができる。   FIG. 3 is a cross-sectional view of the main body portion 2 of the dispensing neck 2. Of the barriers 4, the width of the extraction path is gradually expanded by making the walls positioned at least on both sides into curved walls that are curved toward the inner wall side from the proximal end to the distal end of the extraction neck 2. The contents to be dispensed can be discharged radially (fan-shaped).

障壁４は、注出頚部２の外周壁にプレス加工を施すことにより一体的に形成することができ、この場合には、本体部分２ａの外周壁には、障壁４の数だけ凹所が設けられることになる。   The barrier 4 can be integrally formed by pressing the outer peripheral wall of the pouring neck portion 2. In this case, the outer peripheral wall of the main body portion 2 a is provided with recesses as many as the barrier 4. Will be.

また、図示はしないが障壁４の内壁の一方に凸部を設け、対向するもう一方に凹部を設け、凹部に凸部を嵌合させて形成することも可能であり、この場合は、指等で押し潰して凸部と凹部を嵌合させてシャワー状に注出することができる。障壁４を形成するための方法についてはとくに限定はされない。上掲図３においては障壁４を断面で表示したが、プレス加工を施して成形される場合にはその内部は空洞部分が形成される。   Although not shown, it is also possible to provide a convex portion on one of the inner walls of the barrier 4, provide a concave portion on the opposite side, and fit the convex portion to the concave portion. Can be crushed to fit the convex part and the concave part and poured out in a shower shape. The method for forming the barrier 4 is not particularly limited. In FIG. 3, the barrier 4 is shown in cross section, but when it is molded by pressing, a hollow portion is formed inside.

本発明にしたがう薄肉容器は、ブロー成形により全て一体成形できる単一部材からなっているので、効率的な製造が行えるとともに材料の使用量を減らすのにとりわけ有利である。なお、容器の成形法は射出成形法や従来知られている成形法が適用可能であり、ブロー成形のみに限定されることはない。   The thin-walled container according to the present invention consists of a single member that can be integrally formed by blow molding, which is particularly advantageous for efficient production and reducing the amount of material used. In addition, the injection molding method and the conventionally known molding method can be applied as the container molding method, and the method is not limited to blow molding.

内容物を充填する充填口は、密閉栓２ｂの天面に設けた場合について図示したが、胴体１と注出頚部２の間（肩部）や底部に設けることもできる。   Although the filling port for filling the contents is illustrated in the case where it is provided on the top surface of the sealing plug 2b, it can also be provided between the trunk 1 and the dispensing neck 2 (shoulder) or at the bottom.

また、障壁４の形状については実施例のものには限定されることはなく、例えば、斜め状に形成されたリブ等を適用することも可能であり、このような斜め状に形成されたリブ等によれば内容物の注出方向を適宜変更するのに有利となる。   Further, the shape of the barrier 4 is not limited to that of the embodiment, and for example, an obliquely formed rib or the like can be applied, and such an obliquely formed rib. According to the above, it is advantageous to appropriately change the dispensing direction of the contents.

内容物が注ぎ易く、シャワー状にして内容物を注出することが可能な薄肉容器が提供できる。   It is possible to provide a thin-walled container that can be poured easily and can be poured into a shower.

本発明にしたがう薄肉容器の実施の形態を示した図である。It is the figure which showed embodiment of the thin container according to this invention. 図１に示した容器の開封状態を示した要部外観図である。It is a principal part external view which showed the unsealed state of the container shown in FIG. 注出頚部の本体部分の断面を示した図である。It is the figure which showed the cross section of the main-body part of the extraction neck part.
