The first embodiment of the potion container will be described with reference to the drawings. The portion container 1 of the present embodiment is a container for storing liquid substances such as milk and syrup for coffee and concentrated soup stock for pots in small portions. As shown in FIG. 1, the portion container 1 includes a container body 3 and a lid material sheet 5 attached to the container body 3.

The container body 3 can be formed by using a thermoplastic resin such as polyethylene, polypropylene, polystyrene, polyethylene terephthalate, or polyvinyl chloride. The container body 3 can be formed, for example, by thermoforming a thermoplastic resin sheet. The thermoplastic resin sheet may be a single sheet of any of these, or may be a laminated sheet having a plurality of layers.

The container body 3 is formed in an appropriate shape capable of accommodating a liquid substance and to which the lid material sheet 5 can be satisfactorily attached. As shown in FIGS. 1 and 2, the container body 3 of the present embodiment has an accommodating portion 30 and a flange portion 40 extending outward from the accommodating portion 30.

The accommodating portion 30 is formed in a bowl shape capable of accommodating a liquid substance. The accommodating portion 30 has a bottom surface 31 and a side wall portion 32 that rises upward from the bottom surface 31. The bottom surface 31 is formed in an elliptical shape in this embodiment. The side wall portion 32 is formed so as to surround the bottom surface 31 from the outer edge of the bottom surface 31 over the entire circumference.

A beak-shaped spout 33 is provided in the accommodating portion 30. The spout 33 is provided at a position on the long axis of the elliptical bottom surface 31. Further, the spout 33 is formed in a triangular shape in a plan view, and is provided so that the triangular apex faces outward.

The upper portion of the bowl-shaped accommodating portion 30 is open, in other words, the accommodating portion 30 is provided with an upper opening 34.

When the ratio of the depth of the accommodating portion 30 to the inner diameter of the upper opening 34 is defined as the "deep drawing ratio", the deep drawing ratio is preferably 0.5 or more. When the upper opening 34 is elliptical as in the present embodiment, the average of the inner diameter along the major axis and the inner diameter along the minor axis is considered to be the inner diameter of the elliptical upper opening 34. And. The deep drawing ratio may be 0.55 or more, and may be 0.6 or more.

The capacity of the accommodating portion 30 is appropriately set based on the liquid material accommodating therein and its use. The capacity of the accommodating portion 30 is preferably set based on a necessary and sufficient amount for one use, for example, about 5 to 50 mL.

The flange portion 40 is formed so as to surround the upper opening 34 of the accommodating portion 30 and extend outward. The flange portion 40 is formed so as to extend outward from the upper end of the side wall portion 32. Further, the flange portion 40 is formed in a strip shape having a predetermined width.

On the flange portion 40, a picking piece 42 for opening operation is formed so as to project outward. The picking piece 42 is provided at a position corresponding to the spout 33 of the container body 3, and in the present embodiment, is provided at a position on the long axis of the elliptical accommodating portion 30. The picking piece 42 is formed in a predetermined circumferential region centered on the position of the long axis on the flange portion 40, and is formed to be narrower than the container main body 3. When the container body 3 has an elliptical shape as in the present embodiment, the total width along the minor axis is considered to be the width of the container body 3. The width of the picking piece 42 may be, for example, 0.3 to 0.7 times the width of the container body 3.

The lid material sheet 5 can be formed by using, for example, a thermoplastic resin sheet such as polyethylene, polypropylene, polystyrene, or polyethylene terephthalate, or a metal thin film sheet such as aluminum. The lid material sheet 5 may be a single sheet of any of these, or may be a laminated sheet having a plurality of layers.

The outer shape of the lid material sheet 5 is formed so as to have substantially the same outer shape as the outer shape of the flange portion 40 of the container body 3. The lid material sheet 5 is laminated on the flange portion 40 and covers the upper opening 34 of the accommodating portion 30. The lid material sheet 5 and the container body 3 (flange portion 40) may be bonded via an adhesive layer, or may be integrally fused by heat fusion. In any case, the lid material sheet 5 is completely sealed with respect to the flange portion 40.

In the portion container 1 of the present embodiment, the flange portion 40 is provided with a breaking line 44 that breaks during the opening operation. The break line 44 is provided at the root portion of the picking piece 42 (the region between the picking piece 42 and the spout 33) in the flange portion 40. The break line 44 is broken when the picked piece 42 is raised upward with a fingertip, and can be formed by, for example, a half cut, a perforation cut, a fusing cut, or the like.
