Thus, the container can reliably form air holes for taking out the contents.
図１及び図２において、本発明である容器を射出成形する方法を説明する。可動金型であるキャビ型１と固定金型であるコア型２とで一対の金型が構成される。前記キャビ型１には、合成樹脂高温で溶融する樹脂射出器１ａと前記樹脂射出器１ａと連結し合成樹脂材を外へ流出する射出部１ｂを設けている。図１において、キャビ型１とコア型２が突き合って金型が型締めされた状態を示す。図１のような型締め状態では、キャビ型１の外面型１ｃとコア型２の内面型２ａによって製品形状すなわち容器３が形成され、前記樹脂射出器１ａ内には高温で溶融した合成樹脂材が射出部１ｂから高圧力で射出され、容器３が成形される。前記容器３が硬化した後、キャビ型１がコア型２から後退し、図２に示すように金型が型開きし、成形品が取り出される。 1 and 2, a method for injection molding a container according to the present invention will be described. A pair of molds is constituted by a mold 1 that is a movable mold and a core mold 2 that is a fixed mold. The mold 1 is provided with a resin injector 1a that melts at a high temperature of the synthetic resin and an injection portion 1b that is connected to the resin injector 1a and flows out the synthetic resin material. FIG. 1 shows a state where the mold 1 is clamped by the cavity mold 1 and the core mold 2 abutting each other. In the mold clamping state as shown in FIG. 1, a product shape, that is, a container 3 is formed by the outer mold 1c of the mold 1 and the inner mold 2a of the core mold 2, and the synthetic resin material melted at a high temperature in the resin injector 1a. Is injected at a high pressure from the injection portion 1b, and the container 3 is formed. After the container 3 is cured, the mold 1 is retracted from the core mold 2, the mold is opened as shown in FIG. 2, and the molded product is taken out.
図１乃至図７において、底部側を小径とし、開口部側を大径としたポリプロピレン等の可撓性のある合成樹脂材の有底筒状容器であり、内容物を収容する本体４と前記本体４の下端側に足部５を有し、前記足部５に近接した位置において部分的に除去する為の突起６を前記足部５に沿って形成している。前記突起６の形状は円錐形でも四角錐形でも良い。前記突起６の基部がつながる本体底面部７に薄肉の領域８と薄肉の領域８より厚みのある腕部９とを形成し、前記腕部９を支点にして、かつ、前記腕部９を残し前記本体底面部７から突出した前記突起６を折ることによって内容物取り出し用の空気穴１０を形成可能とした容器３である。前記腕部９は、図に示すとおり複数であっても１つでも良く、突起６と足部５の間にゲート位置１１を設け、薄肉の領域８でゲート位置１１から離れた位置をウエルドラインの交差点１２として設定することによって確実に内容物取り出し用の空気穴１０を形成させることができる容器である。 1 to 7, a bottomed cylindrical container made of a flexible synthetic resin material such as polypropylene having a small diameter on the bottom side and a large diameter on the opening side, the main body 4 containing contents and the above-mentioned A foot 5 is provided on the lower end side of the main body 4, and a protrusion 6 is formed along the foot 5 for partial removal at a position close to the foot 5. The shape of the protrusion 6 may be a conical shape or a quadrangular pyramid shape. A thin-walled region 8 and an arm portion 9 thicker than the thin-walled region 8 are formed on the bottom surface portion 7 of the main body to which the base of the protrusion 6 is connected, and the arm portion 9 is left as a fulcrum. This is a container 3 in which an air hole 10 for taking out contents can be formed by folding the protrusion 6 protruding from the bottom surface portion 7 of the main body. The arm portion 9 may be plural or one as shown in the figure, and a gate position 11 is provided between the protrusion 6 and the foot portion 5, and a position apart from the gate position 11 in the thin region 8 is a weld line. This is a container in which the air hole 10 for taking out the contents can be surely formed by setting as the intersection 12 .
図８において、樹脂の流れによるウエルドラインについて説明する。ウエルドラインとは、樹脂の流れ線のことであり、図８の破線矢印のようにゲート位置１１から足部５方向に樹脂が流れ、前記突起６部分で分流され再び合流する。その際に交差する地点をウエルドラインの交差点１２であり、前記突起部分で分流した樹脂が再び合流する地点、すなわち樹脂がちょうど重なり合う地点を薄肉の領域８内で設定することで裂けやすく確実に内容物取り出し用の空気穴１０を形成させることができる容器３になる。薄肉の領域８は、前記容器底面部７と前記突起６の間に設けられた前記容器底面部７より薄肉になっている部分のことである。 In FIG. 8, the weld line by the flow of the resin will be described. The weld line is a flow line of the resin, and the resin flows from the gate position 11 toward the foot 5 as shown by the broken line arrow in FIG. In this case, the intersecting point is the weld line intersection 12, and the point where the resin divided by the protrusions merges again, that is, the point where the resin just overlaps, is set within the thin-walled region 8 so that the contents can be easily torn. It becomes the container 3 in which the air hole 10 for taking out an object can be formed. The thin region 8 is a portion that is thinner than the container bottom surface portion 7 provided between the container bottom surface portion 7 and the protrusion 6.
