Abstract

PURPOSE:To obtain an individual package free from scattering of contents at the time of unpacking by making a constitution wherein a deformable part of a container bottom takes a protrusion shape with a rib part as a border when a lid material part is pressed. CONSTITUTION:Into a container 6 obtained by vacuum-molding a polypropylene sheet with a part 3 deformable into either a recess or a protrusion into a protrusion via a rib part 2 having a hinge effect along an inner periphery of a bottom 1, concentrated coffee of 80 deg.C is put with the deformable part 3 in a protrusion, and after the container is heat-sealed with a lid material 5 of an aluminum foil to be completely sealed, the deformable part 3 is deformed into a recess to have an individual package completed. When the lid material 5 is pressed by a finger at the time of use, the deformable part 3 is in a protrusion to reduce a pressure inside the container 6 so that a liquid level of the concentrated coffee 4 further lowers. When the content 4 is to be put in at a room temperature, the deformable part 3 is deformed into a recess and the contents is put, and then the lid material is heat-sealed, while by pressing the lid material 5 with a finger at the time of use, the deformable part 3 is deformed in a protrusion to reduce a pressure inside the container. Therefore the content may not scatter when the lid material is removed from the container.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to individual portion bags (individual packaging) for milk, concentrated coffee dressing, etc. that prevent the contents from scattering when opened. .

C) Conventional technology) Conventionally, individual packaging for milk, concentrated coffee, etc. is shown in Figures 6 and 7rI! As shown in Figure 8, individual packaging is used, in which the contents are filled into a container made of polystyrene, polypropylene, etc., and then heat-sealed with a material made of aluminum foil. When the lid material is removed from the container, the contents may be vibrated or, especially if the container is pressed with one's fingers, the inside of the container may be pressurized and scattered, staining clothes and hands.

(Problems to be Solved by the Invention) The present invention solves these drawbacks, and provides an individual package in which the contents do not scatter when the package is opened.

(Means for Solving the Problems) In the present invention, a container having a portion that can be deformed into an uneven shape along the periphery of the bottom portion through a rib portion having a hinge effect is filled with liquid contents, and a lid material is The package is hermetically sealed, and when the lid is pressed during opening, the deformable portion at the bottom becomes convex with the rib as a boundary, and when the lid is opened from the container, the contents are It is an individual package that is characterized by not scattering.

(Example) The present invention will be explained with reference to the drawings according to one embodiment.

As shown in Figure ta1, a portion (3) that can be deformed into an uneven shape is formed along the inner periphery of the bottom (1) from a polypropylene sheet with a thickness of <0.4 mm via a rib portion (2) having a hinge effect. A container (6) obtained by vacuum forming is filled with 188 cc of concentrated coffee at 80°C with the deformable portion (3) shaped into a convex shape as shown in Fig. 2, and At foil with easy-open adhesive is attached. After completely sealing by heat sealing with the lid material (5), the deformable portion (3) was deformed into a concave shape as shown in FIG. 3 to complete an individual package. When the material (5) is pressed with a finger as shown in Fig. 4 during use, the deformable portion (3) becomes convex and the inside of the container (6) becomes depressurized, and the concentrated coffee (4)
) will drop, and the lid material (5) will drop as shown in Figure 5.
Even when the package is opened, the coffee (4) can be poured without scattering, and if the contents (4) are filled at room temperature, such as milk, the deformable part (3) can be deformed into a concave shape for filling. After that, the seven pieces of material (5) are heat-sealed to complete an individual package. When the lid (5) is pressed with a finger during use, the deformable portion (3) deforms into a convex shape, and the inside of the container (6) becomes depressurized, as shown in Figure 5, when the lid (5) is opened. Even at times, the contents (4) did not scatter.

The material for the container (6) used here is preferably polypropylene resin, which has a hinge effect, but polystyrene resin or vinyl chloride resin may also be used, and if barrier properties are required, vinylidene chloride or ethylene vinyl acetate may also be used. Saponified polymers may also be laminated or coated.

(Effects of the invention) The individual package of the invention can be opened without the contents scattering when the lid material is opened from the container.
