Description

  The present invention relates to a blow-molded thin-walled container that enables the volume of the filling space to be reduced according to the content being dispensed, stably performing the cutting operation when opening the container, and reliably cutting the plug body. It is possible to do.

In the field of containers for shampoos, rinses, liquid soaps, cosmetics, etc., thin-walled containers are increasingly used from the viewpoint of effective use of resources and reduction of waste (for example, see Patent Document 1). ).
JP 2004-352328 A

  A conventional container of this type is provided with a notch and a planned break line in the pouring part in advance, grips the container body side, twists the plug body, and plugs the plug body along the notch and the planned break line. However, since the container body was thin and easily deformed, it was difficult to perform a stable cutting operation when the container was opened, and there was still room for improvement in this regard.

  The subject of this invention exists in the place which proposes the novel blow molding thin wall container which can eliminate the above conventional malfunctions which arose when opening a container.

The present invention is a blow-molded thin-walled container provided with a thin-walled body that enables volume reduction of the filling space according to the contents being poured out,
At the upper end corner of the body, there is provided a pouring part that has a passage connected to the filling space and opens the passage by cutting and separating the plug body along the planned breaking line to discharge the contents in the filling space. ,
A first knob that is gripped when the plug body is cut and separated is disposed on the main body side of the pouring section, and extends on the same line as the first knob section on the plug body side. A second knob for cutting and separating the plug body along a planned cutting line by pulling it in a direction away from the knob is arranged, and the first knob and the second knob have a peripheral edge. Only the portion is formed thick , and the second knob has an edge connected to the planned fracture line, and the edge of the first knob and the second knob adjacent to the edge. A blow-molded thin-walled container characterized in that a substantially V-shaped notch is formed by the edge of the part .

In blow molding thin-walled container made to the above configuration, preferably provided with thin pieces connected to each other through a breakable line the first knob portion and the second knob portion.

  By grasping the first knob part and the second knob part and pulling them away from each other, the plug body is separated from the main body side of the extraction part, and the container body is deformed when the container is opened. Therefore, a stable cutting operation can be realized and reliable cutting can be performed.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 shows a blow molded thin container (made of synthetic resin) according to the present invention. In the figure, reference numeral 1 denotes a body of a container that defines a filling space for contents. The body 1 has a small thickness so that the filling space can be reduced according to the degree of the content to be poured out.

Reference numeral 2 denotes a pouring portion provided at the upper end corner of the body 1. The pouring part 2 has a passage 2a connected to the filling space, and a stopper 2b is provided at the tip thereof. Reference numeral 3 denotes a planned fracture line formed thinly by cutting or the like, and reference numeral 4 denotes a first knob part which is integrally disposed on the container body side of the pouring part 2 and is gripped when the stopper 2b is cut and separated. The edge 4a of the first knob 4 can be made thick, and the inner region 4b of the edge 4a can be made thin (only the peripheral edge , that is, the edge 4a is thick). This makes it easier to place a finger.

Reference numeral 5 denotes a second knob that is integrally disposed on the plug body 2b side. The second knob 5 extends on the same line as the first knob 4 and is pulled away from the first knob 4 as shown in FIG. The edge 5a can be made thick like the first knob 4 and the inner region 5b of the edge 5a can be made thin (periphery , ie, edge). 5a only is formed thicker), in particular the cutting of the second edge portion 5a ₁ of the knob portion 5 extend until breakable line 3 as shown in FIG. 3 (connect) that the plug 2b, and separation It becomes possible to make it more reliable.

  Each of the edge of the first knob 4 (the edge located on the planned fracture line 3 side) and the edge of the second knob 5 adjacent to this edge open outward from the lower end toward the upper end. The container is opened easily by forming a substantially V-shaped notch n.

  Moreover, the plug body in the distribution | circulation stage of goods is provided by providing the thin piece 6 as shown in FIG. 4 which connects the 1st knob | pick part 4 and the 2nd knob | pick part 5 through the cutting projected line 3, and mutually connects. Inadvertent cutting and separation of 2b can be avoided.

  The shape of the 1st knob | pick part 4 and the 2nd knob | pick part 5 can be changed suitably, and is not limited only to the example of illustration.

  The angle θ (see FIG. 1) formed by the ground contact surface of the container and the planned fracture line 3 is 5 to 90 °, more preferably 10 to 60 °. When the angle θ is set to such an angle, not only the plug 2b can be easily cut and separated but also the contents can be poured easily.

  The container of this invention can be comprised with a synthetic resin. The molding method can be formed into a desired shape by applying a conventionally known blow molding method, and is not limited to the illustrated shape.

  Examples of the contents filled in the container of the present invention include liquids, fluids, oils and fats, liquids containing surfactants, or foods (for example, fluids such as jelly and liquids such as soups). .

  Blow-molded thin-walled container that prevents the contents from spilling due to deformation of the container body when the container is cut and separated to open the container, and the stopper can be reliably cut by a stable cutting operation Can be provided.

It is the figure which showed embodiment of the blow molding thin wall container according to this invention. It is the figure which showed the opening condition of the container. It is the figure which expanded and showed the principal part of the blow molding thin wall container according to this invention. It is the figure which showed the reference technique of the blow molding thin wall container according to this invention about the principal part.
