Description

本発明は押出し容器に関する。 The present invention relates to extruded containers.

従来、マヨネーズ、ケチャップ、おろしワサビ又はおろし生姜などの練り状乃至ペースト状の食品、あるいはクリーム状の化粧料、洗顔料などの内容物を収容する用途に用いられる容器として、スクイズボトルやチューブ容器などの、胴部が押圧により変形して内容物を絞り出し可能に構成されて成る合成樹脂製の押出し容器が広く用いられている。 Squeeze bottles, tube containers, etc. have traditionally been used to store the contents of dough or paste foods such as mayonnaise, ketchup, grated wasabi, or grated ginger, or creamy cosmetics and facial cleansers. Extruded containers made of synthetic resin, whose bodies are deformed by pressure so that the contents can be squeezed out, are widely used.

例えば特許文献１には、低密度ポリエチレンを主材とした合成樹脂材料を押出ブロー成形（ＥＢＭ：Ｅｘｔｒｕｓｉｏｎ Ｂｌｏｗ Ｍｏｌｄｉｎｇ（以下同様））することにより、筒状の口部と、口部の下端から径方向外側に向けて延びる肩部と、肩部の下端に連なる筒状の胴部と、胴部の下端を閉塞する閉塞部（底部）とを備えたボトル形状を成すとともに、胴部が押圧により変形して内容物を絞り出し可能に構成されている合成樹脂製の押出し容器が記載されている。 For example, in Patent Document 1, by extrusion blow molding (EBM: Extrusion Blow Molding (hereinafter the same)) a synthetic resin material mainly made of low-density polyethylene, a cylindrical opening and a diameter from the lower end of the opening are formed. It has a bottle shape with a shoulder extending outward in the direction, a cylindrical body connected to the lower end of the shoulder, and a closing part (bottom) that closes the lower end of the body. A synthetic resin extrusion container is described that is configured to be deformable and squeeze out the contents.

Vertical folded portions 6 are formed respectively. The body part 4 can be elastically deformed inward at vertical folding parts 6 provided at both ends of the right side c and the left side d, where the body part 4 at the front a and the body part 4 at the rear b contact each other. It is composed of
Note that the deformation of the body portion 4 may be elastic deformation as described above, or may be plastic deformation.

肩部３は口筒部２と胴部４との間に設けられており、図１又は図２に示すように、肩部３の前方ａ（後方ｂも同様）には、図示上方に向かって凸を成す正面視略半楕円形の面から成る第１肩側部３Ａが形成され、肩部３の右方ｃ及び左方ｄには、側面視略三角形状の面から成る第２肩側部３Ｂが形成されている。そして、第１肩側部３Ａと第２肩側部３Ｂとは、その間に設けられた境界辺３Ｃにおいて折り曲げられている。
境界辺３Ｃは、図１に示すように中央部が図示上方に向かって凸を成す略半楕円形（略半猫目状）で形成されている。そして、境界辺３Ｃの下端部は、直線状又は僅かな略円弧凹形状を有して右方ｃ及び左方ｄに設けられた両鉛直折り返し部６の上端に向かって延びる態様が好ましい。 The shoulder part 3 is provided between the mouth barrel part 2 and the body part 4, and as shown in FIG. A first shoulder side portion 3A is formed with a substantially semi-elliptical surface when viewed from the front and has a convex shape, and second shoulders are formed on the right side c and the left side d of the shoulder portion 3 and are formed from a generally triangular surface when viewed from the side. A side portion 3B is formed. The first shoulder side portion 3A and the second shoulder side portion 3B are bent at a boundary side 3C provided therebetween.
As shown in FIG. 1, the boundary side 3C is formed into a substantially semi-elliptical shape (substantially semi-cat-like) with a central portion convex upward in the figure. It is preferable that the lower end of the boundary side 3C has a straight line or a slightly substantially arcuate concave shape and extends toward the upper end of both vertical folded portions 6 provided on the right side c and the left side d.

肩部３の第１肩側部３Ａと胴部４との境界部分（図１のＡ－Ａ線に沿う部分）は水平折り返し部７が周設されており、この水平折り返し部７には容器内方に向かって細溝状に形成されて成る複数の横溝８（本実施例では、前方ａに２つ、後方ｂに２つの合計４つ）が周方向に間欠的に配置されている。そして、第１肩側部３Ａの前方ａ（後方ｂも同様）中央の位置で、且つ右方ｃの横溝８と左方ｄの横溝８との間には、平面視略半円形状を有して凹状に陥没設されて成る押出し部９が夫々に形成されている。押出し部９は第１肩側部３Ａの内面から容器内方に向かって凸状に突出しており、また押出し部９の下端部９ａは、水平折り返し部７（図１のＡ－Ａ線）上に設けられている。
そして、肩部３の第１肩側部３Ａは、水平折り返し部７（図１のＡ－Ａ線）において胴部４に対して谷折り状に折り畳み可能であり、前方ａの胴部４と後方ｂの胴部４とが互いに接触する容器内方に向かって弾性変形可能に構成されている（図４参照）。
尚、複数の溝部８が形成されていなくても水平折り返し部７において折り畳むことは可能であるが、図１のＡ－Ａ線上に沿って複数の溝部８を設けることにより、水平折り返し部７における折り畳みを容易とすることが可能となる。 A horizontal folded part 7 is provided around the boundary between the first shoulder side part 3A of the shoulder part 3 and the body part 4 (the part along line AA in FIG. 1). A plurality of lateral grooves 8 (in this embodiment, two in the front a and two in the rear b, a total of four) formed in a narrow groove shape toward the inside are arranged intermittently in the circumferential direction. The first shoulder side portion 3A has a substantially semicircular shape in plan view at the center position of the front a (the same applies to the rear b) and between the lateral groove 8 on the right side c and the lateral groove 8 on the left side d. An extruded portion 9 is formed in a concave manner. The extruded portion 9 protrudes in a convex shape from the inner surface of the first shoulder side portion 3A toward the inside of the container, and the lower end portion 9a of the extruded portion 9 is located above the horizontal folded portion 7 (line AA in FIG. 1). It is set in.
The first shoulder side part 3A of the shoulder part 3 can be folded in a valley-fold shape with respect to the body part 4 at the horizontal folding part 7 (line AA in FIG. It is configured to be elastically deformable toward the inside of the container where the rear body portion 4 and the body portion 4 are in contact with each other (see FIG. 4).
Although it is possible to fold at the horizontal folding part 7 even if a plurality of grooves 8 are not formed, by providing a plurality of grooves 8 along line AA in FIG. It becomes possible to make it easy to fold.

口筒部２は、その外周面に雄ネジ２ａが刻設されており、図示しないキャップの螺着が可能となっている。また底部５は、図３Ｃに示すようにパリソン下端の食い切り跡である食切り部５ａを介して閉塞されている
尚、キャップが吐出口を備える注出キャップである場合あっては、残留内容物を押し出す前に、キャップを口筒部２から螺脱させて取り外し、その後に後述するような内容物の押し出し操作が行われる。またキャップが吐出口を備えない蓋体である場合には、口筒部３が内容物の吐出口として機能することになる。 The mouth tube portion 2 has a male thread 2a carved on its outer circumferential surface, allowing a cap (not shown) to be screwed onto the mouth tube portion 2. In addition, the bottom part 5 is closed via a cutout part 5a, which is a cutout mark at the lower end of the parison, as shown in FIG. Before extruding the contents, the cap is unscrewed and removed from the mouth barrel portion 2, and then the contents are extruded as described below. Further, when the cap is a lid body without a discharge port, the spout portion 3 functions as a discharge port for the contents.

次に、上記構成からなる押出し容器１の作用効果について図４乃至図７を参照しつつ説明する。
本発明の押出し容器１では、胴部４を容器内方に向かって押圧すると、胴部４が両端の鉛直折り返し部６において折り畳まれ、すなわち前方ａの胴部４と後方ｂの胴部４とが互いに接触して略扁平状に変形させられ、胴部４内に収容されている内容物を口筒部２を通じて外部に吐出させることが可能となっている。 Next, the functions and effects of the extruded container 1 having the above structure will be explained with reference to FIGS. 4 to 7.
In the extruded container 1 of the present invention, when the body 4 is pressed inward, the body 4 is folded at the vertical folds 6 at both ends, that is, the body 4 at the front a and the body 4 at the rear b. are in contact with each other and are deformed into a substantially flat shape, making it possible to discharge the contents housed in the barrel section 4 to the outside through the mouth tube section 2.

大部分の内容物が吐出され、押出し容器１内の内容物の残量が少なくなった場合には、例えば押出し容器１を倒立姿勢にして内容物を口筒部２及び肩部３近傍に集めた後、図４に示すように水平折り返し部７において胴部４に対して肩部３の第１肩側部３Ａを谷折り状に折り畳む第１使用状態に設定する。 When most of the contents have been discharged and the remaining amount of the contents in the extrusion container 1 is small, for example, the extrusion container 1 may be placed in an inverted position to collect the contents near the mouth tube portion 2 and the shoulder portion 3. After that, as shown in FIG. 4, the first use state is set in which the first shoulder side portion 3A of the shoulder portion 3 is folded in a valley-fold shape with respect to the body portion 4 at the horizontal folding portion 7.

第１使用状態では、水平折り返し部７において第１肩側部３Ａが谷折り状に折り畳まれると同時に、境界辺３Ｃにおいては前方ａ及び後方ｂに設けられた両第１肩側部３Ａが第２肩側部３Ｂに対して山折り状に折れ、両第１肩側部３Ａが口筒部２の下端に接近することになる（図４参照）。これにより、両第１肩側部３Ａが、肩部３内に集まっていた残留内容物を口筒部２側に押し込むことが可能となる。 In the first usage state, the first shoulder side portion 3A is folded into a valley-fold shape at the horizontal folding portion 7, and at the same time, at the boundary side 3C, both first shoulder side portions 3A provided at the front a and the rear b are folded into a valley-fold shape. It is bent into a mountain-fold shape with respect to the second shoulder side portion 3B, and both first shoulder side portions 3A approach the lower end of the mouth tube portion 2 (see FIG. 4). Thereby, both the first shoulder side parts 3A can push the residual contents gathered inside the shoulder part 3 into the mouth barrel part 2 side.

この際、両第１肩側部３Ａに設けられ且つ容器内方に向かって凸状に突出している一対の押出し部９が、肩部３内の残留内容物を口筒部２に向かって押し出すことが可能となる。よって、これまで以上に残留内容物が口筒部２側に押し込まれ易くなり、口筒部２を通じて外部に押し出すことが可能となるため、残量内容物を効果的に低減することができる。 At this time, a pair of push-out portions 9 provided on both first shoulder side portions 3A and protruding convexly toward the inside of the container push out the remaining contents within the shoulder portion 3 toward the mouth barrel portion 2. becomes possible. Therefore, the remaining contents are more easily pushed into the mouth barrel part 2 side than before, and can be pushed out to the outside through the mouth barrel part 2, so that the amount of remaining contents can be effectively reduced.

次に、第１使用状態においても押し出せない少量の残留内容物については、図５乃至図７に示すように、前方ａに設けられた水平折り返し部７においては胴部４に対して第１肩側部３Ａを山折り状に折り曲げ、後方ｂに設けられた水平折り返し部７においては胴部４に対して第１肩側部３Ａを谷折り状に折り曲げることにより、全体として口筒部２及び肩部３が容器軸Ｏに対して約９０度に折り畳まれる第２使用状態に設定する。 Next, for a small amount of residual content that cannot be pushed out even in the first use state, as shown in FIGS. By folding the shoulder side portion 3A into a mountain fold shape, and by folding the first shoulder side portion 3A into a valley fold shape with respect to the body portion 4 at the horizontal folding portion 7 provided at the rear b, the mouth tube portion 2 is formed as a whole. Then, the container is set to a second use state in which the shoulder portion 3 is folded at approximately 90 degrees with respect to the container axis O.

第２使用状態では、両第１肩側部３Ａに設けられ且つ容器内方に向かって凸状に突出している一対の押出し部９の下端部９ａ同士が互いに接近し、図６に示す正面図では、一対の押出し部９が全体として略円形状を成す状態で口筒部２に対向するようになる。この状態では、図５及び図７に白抜き矢印で示すように、両手の親指等で一対の押出し部９を口筒部２の先端に向けて夫々押圧することが可能となる。よって、この押圧により残留内容物を口筒部２内により積極的に押し込むことが可能となり、結果として内容物を口筒部２を通じて容易に押し出すことができ、残量内容物をより効果的に低減することが可能となる。 In the second use state, the lower ends 9a of the pair of extrusion parts 9 provided on both first shoulder side parts 3A and protruding convexly toward the inside of the container approach each other, and the front view shown in FIG. Now, the pair of extruded parts 9 come to face the mouth tube part 2 in a generally circular shape. In this state, as shown by the white arrows in FIGS. 5 and 7, it becomes possible to press the pair of extrusion parts 9 toward the tip of the mouth barrel part 2 with the thumbs of both hands, respectively. Therefore, this pressure makes it possible to push the remaining contents into the mouth barrel part 2 more actively, and as a result, the contents can be easily pushed out through the mouth barrel part 2, and the remaining contents can be pushed out more effectively. It is possible to reduce the

また第２使用状態では、肩部３と胴部４との間が水平折り返し部７において約９０度に折り曲げられるため、残留内容物を肩部３から口筒部２にかけての空間内に集めることができると共に、押圧した際に、集まっている残留内容物を堰き止め、肩部３から胴部４側に逆流することを防止できる。よって、残留内容物を確実に口筒部２内に押し込むことが可能となる。 Furthermore, in the second use state, the space between the shoulder portion 3 and the body portion 4 is bent at approximately 90 degrees at the horizontal folding portion 7, so that residual contents are collected in the space from the shoulder portion 3 to the mouth tube portion 2. At the same time, when pressed, it is possible to dam up the collected residual contents and prevent them from flowing back from the shoulder section 3 to the body section 4 side. Therefore, it becomes possible to reliably push the remaining contents into the mouth barrel portion 2.

更に、境界辺３Ｃの下端部が直線状又は僅かな略円弧凹形状に形成される好ましい態様では、第２使用状態にすると、図７に示すように、第２肩側部３Ｂの上面も直線状又は僅かな略円弧凹形状となる。よって、後方ｂの位置では人指し指等の腹で第２肩側部３Ｂを容易に押さえ込むことが可能となる。更に前方ａの位置では残りの親指を使用し、両第１肩側部３Ａに設けられた一対の押出し部９を口筒部２に向けて容易に押圧することが可能となる。よって、押出し操作時における操作性を向上させることが可能となり、これまで以上に残留内容物を効果的に押し出すことが可能となる。 Furthermore, in a preferred embodiment in which the lower end of the boundary side 3C is formed in a straight line or in a slightly substantially arcuate concave shape, in the second use state, the upper surface of the second shoulder side 3B is also straight, as shown in FIG. It becomes a shape or a slight concave shape. Therefore, at the rear position b, it becomes possible to easily press down the second shoulder side portion 3B with the pad of the index finger or the like. Further, at the forward position a, it becomes possible to easily press the pair of extrusion parts 9 provided on both first shoulder side parts 3A toward the mouth barrel part 2 using the remaining thumb. Therefore, it becomes possible to improve the operability during the extrusion operation, and it becomes possible to extrude the remaining contents more effectively than ever before.

以上、実施例に沿って本発明の構成とその作用効果について説明したが、本発明の実施の形態は上記実施例に限定されるものではない。
例えば、上記実施例の第２使用状態では、口筒部２及び肩部３を後方ｂに折り畳んだ構成を示して説明したが、前方ａに折り畳む構成とするものであっても良い。 Although the structure of the present invention and its effects have been described above with reference to Examples, the embodiments of the present invention are not limited to the above-mentioned Examples.
For example, in the second usage state of the above-described embodiment, the mouth tube part 2 and the shoulder part 3 are shown and described as being folded backward b, but they may be folded forward a.

また上記実施例では、押出し部９の形状として略半円形状の構成を示して説明したが、押出し部９は略半円形状に限定されるものではなく、その他の形状であっても良い。 Further, in the above embodiment, the shape of the extruded portion 9 has been described as being approximately semicircular, but the extruded portion 9 is not limited to the approximately semicircular shape, and may have other shapes.

また上記実施例では押出し容易１として、底部５が食切り部５ａを介して閉塞された壜体型の容器を示して説明したが、本発明はこれに限られるものではなく、底部５が扁平状にシールされたチューブ型の容器であっても良い。 Further, in the above embodiment, a bottle-shaped container in which the bottom part 5 is closed via the cutout part 5a is shown and explained as the easy extrusion 1, but the present invention is not limited to this, and the bottom part 5 is in a flat shape. It may also be a sealed tube-shaped container.

本発明は、押出し容器の分野における用途展開を更に広い領域で図ることができる。 The present invention can be applied to a wider range of applications in the field of extruded containers.
