Description

Instant food container {INSTANT FOOD CONTAINER}

The present invention relates to a container for storing instant food such as fried noodles or instant noodles.

This type of container for instant food runs the flange outwardly from the entire circumference of the upper circumference of the upper opening of the container body in which the instant food is accommodated, and thermally fusion-bonds the lid on the sheet over the entire circumference of the upper surface of the flange. By doing so, the upper opening part of the container body is closed in a sealed state.

By the way, since the width | variety of the contact surface of the flange of a container main body and the inner surface of a lid is the same over the whole circumference, the adhesive force with the flange of a lid is the same strength over the whole circumference.

For this reason, when opening the inlet of boiling water in order to call instant food at the time of a meal, a part of a lid is pulled out and pulled off, but at this time, a lid may be peeled too much and it opens larger than necessary.

In this way, when the lid is opened too much, there is a problem that it is not possible to close the lid sufficiently when the lid is temporarily closed until the instant food is called after pouring the hot water.

In addition, when the instant food is fried noodles, a hot water draining hole is formed in the container body for discharging the hot water after the fried hot water is called, and when the hot water is taken out, a part of the lid covering the hot water is pulled out to remove the hot water. At this time, too, there was a problem of peeling too much, and there was a problem that the fried noodle called by this flowed out of the hot water together with the hot water.

The purpose of the present invention is to solve such a problem, and to provide an instant food container that can prevent excessive opening of the lid when the lid is heat-sealed to the flange of the container body.

The present invention consists of a container body made of synthetic resin of the upper opening shape, and a sheet-shaped lid that closes the upper opening part of the container body, and the container body runs a flange outward from the entire circumference of the upper circumference of these openings. In the container for instant food, wherein the inner surface of the lid is heat-sealed so that the inner surface of the lid is re-peelable over the entire circumference of the upper surface of the flange, two protrusions higher than the upper surface of the flange are formed at predetermined intervals on the upper surface of the flange. It is characterized in that the adhesive force to the inner surface of the lid is made stronger than any other point than the protrusion on the upper surface of the flange.

In this case, the part corresponding to the upper part between the protrusion parts of the said lid can be re-peelable so that it may open a hot water inlet or a hot water extraction hole.

In addition, the whole or part of said protrusion part can be formed so that it may protrude inward rather than the inner periphery of a flange.

The container for instant food having the above-described structure is pulled out from the upper surface of the flange of the container body by peeling off the portion corresponding to the upper part between the protrusions of the lid during hot pouring or hot pouring, so that the protrusions have strong adhesive force with the lid. Since the operating force for pulling and removing the lid is more strongly required, opening of the lid over the protruding portion is suppressed.

This makes it possible to reliably open the lid in the range of the opening opening necessary for pouring or pouring out the water, and preventing excessive opening.

If all or part of the protrusion is formed to protrude inwardly from the inner circumference of the flange, the heat fusion area with the inner surface of the lid can be increased by the amount protruding inward from the inner circumference of the flange of the protrusion. As a result, the adhesive force at the protrusion can be further strengthened, and excessive opening of the lid can be reliably prevented.

(Example)

A very suitable embodiment of the present invention will be described based on the drawings.

1 is a plan view of a container main body of an instant food container, FIG. 2 is a sectional view taken along the line AA in FIG. 1, FIG. 3 is a sectional view taken along the line BB in FIG. 1, FIG. 4 is a CC in FIG. 5 is a cross-sectional view taken along the line DD in FIG. 1.

The container for instant food according to the present invention, as shown in Figs.

The container body (1) is formed of a thermoplastic synthetic resin sheet such as foamed polystyrene or non-foamed resin such as polyethylene terephthalate by hot plate molding. In the exemplary embodiment shown in the drawing, the plane is molded into a rectangular main shape. have.

The container body 1 of the illustrated example is formed in a rectangular main shape with a plane having a rectangular bottom wall 3 and a circumferential wall 5 raised upwardly from the entire circumference of the bottom wall 3 in an open state. The flanges 6a, 6b, 6c, and 6d are formed out of the entire circumference of the upper opening circumference of the circumferential wall 5 in a rectangular shape to the outside.

The outer circumferential circumference 61 of the flanges 6a, 6b, 6c, and 6d is formed in a downwardly curved shape.

Then, protrusions 7 and 7 are flanges 6a and 6b on the upper surfaces of the flanges 6a and 6b of two adjacent sides of the flanges 6a, 6b, 6c and 6d. It is formed so that it is slightly higher (for example, about 2 mm) than the upper surface.

These two protrusions 7, 7 are formed in a substantially rectangular plane, as shown in the example shown in the figure, or other planar polygonal shapes, planar circles, planar ovals, or the like, so that the entirety or the entirety of the protrusions 7 is shown. As an example, a part 7a of the protruding portion 7 is formed in a shape protruding inward from the inner circumference of the flanges 6a and 6b.

On the upper surface of the corner part where the two flanges 6c and 6d of other two sides intersect, the drain part 8 is formed.

As shown in FIG. 4, FIG. 5, the hot water draining part 8 has the peak part 9 of the same height as the upper surface of flange 6c, 6d, and the flange 6c, 6d on both sides of this peak part 9 (d). Has a groove (10), (10) formed lower than the upper surface of the), the inner terminal of the groove 10 is formed so as to communicate with the interior of the container body 1, the outer terminal is a flange (6c) (6d) is formed in the shape which is occluded, and it is made to fuse | melt in the sealed state by the lid 2.

On the upper surfaces of the flanges 6c and 6d on both sides of the grooves 10 and 10, the protruding portions 12 and 12 are slightly higher than the upper surfaces of the flanges 6c and 6d. For example, about 2 mm).

These two protrusions 12 and 12 are formed in a substantially rectangular plane like the protrusions 7 and 7 described above, and thus the protrusions 12 as a whole or the illustrated example of the protrusions 12. A part 12a of the part is formed in the shape which protrudes inward rather than the inner periphery of flange 6c, 6d.

On the other hand, as shown in FIG. 2, the lid 2 forms the printing layer 14 on the surface of the base material 13 made of paper or synthetic resin, and a waterproof layer such as aluminum foil or silica deposition on the back surface of the base material 13. (15) and the heat-sealing resin layer 16 are formed by laminating a flexible laminated sheet in the form of a rectangular sheet having a size of closing the upper opening of the container body 1.

In the container body 1 configured as described above, as an instant food 17, for example, fried noodles are accommodated, and on the instant food 17, fried noodle sauce in a bag, fish meat in a bag, and seaweed as powder Homemade food 18 is attached.

Thereafter, the lid 2 is mounted horizontally on the upper surfaces of the flanges 6a, 6b, 6c, and 6d of the container body 1 and corresponds to the upper flange of the lid 2 by heating press. The points are heated and pressurized with respect to the flanges 6a, 6b, 6c, and 6d.

As a result, the lid 2 is heat-sealed so as to be re-peelable over the entire circumference of the upper surfaces of the flanges 6a, 6b, 6c, and 6d via the heat-sealing resin layer 16. The upper opening of 1) is closed in a sealed state.

In heat fusion of the lid 2, the heating press presses the entire circumference of the outer circumferential region of the upper surface of the lid 2 from the upper side with an equal pressure, so that the flanges 6a, 6b, 6c, 6d In the protrusions 7, 7, 12, and 12 that are higher than the upper surface of the protrusions, the protrusions 7 are pressed by the height of the protrusions, and they are pressurized more strongly than other places, so that the protrusions 7, 7, 12, Adhesion strength is different from the compressive strength in (12) and the compressive strength in other places except the protrusions (7), (7), (12), and (12), so that the protrusions (7), (7), In (12) and (12), it adheres strongly, and in other places of the latter, adhesive force becomes weaker than that.

Accordingly, the outer circumference of the lid 2 corresponding to the upper portions of the protrusions 7 and 7 prior to injecting the hot water for the instant food 17 into the container body 1 at the time of pre-meal cooking. The hot water inlet is opened by holding a part and pulling it off as a starting point. However, since the adhesive force with the lid 2 is strong with the protrusions 7 and 7, the pull-in force is stronger than that of the pulling force. Strength is needed.

For this reason, the lid 2 is prevented from being opened beyond the protrusions 7 and 7 and can be prevented from opening excessively more than necessary.

In addition, since the heat fusion area with the inner surface of the lid 2 can be increased by the amount 7a projecting inward from the flange inner circumference of the protrusion 7, the adhesive force at the protrusion 7 can be further strengthened. It is possible to prevent excessive opening of the lid 2 more securely.

In this way, the fried noodle sauce in the bag, the fish meat in the bag, the food 18 made of powdered laver, etc. are removed from the open hot water inlet, and then hot water is injected.

The hot water inlet is temporarily blocked by the lid 2 until the instant food 17 is called after the hot water is injected. In this case, since the predetermined amount of opening is opened without excessively opening, the hot water inlet is opened. Can easily be sufficiently occluded.

After the instant food 17 is called, the hot water outlet part 8 is opened by pulling and peeling the outer circumferential circumference of the lid 2 correspondingly upward between the protrusions 12 and 12, but the protrusions 8 12) and 12, the adhesive force with the lid 2 is strong, so that the protrusions 12 and 12 are not excessively opened, and at the same time the external terminal of the groove 10 is opened. It can be opened by a predetermined opening amount covering the upper end of the inner terminal portion.

In addition, as in the case of the projecting portion 7 of the hot water inlet, the heat-sealing area with the inner surface of the lid 2 is increased by the amount of the projecting portions 12 and 12 projecting inwardly from the inner circumference of the flange. Since the adhesive force in the protruding portions 12 and 12 can be further strengthened, excessive opening of the lid 2 can be prevented more reliably.

In this way, by opening the hot water draining unit 8 by a predetermined amount of opening, the instant food 17 can be prevented from flowing out of the hot water draining groove 10 when the hot water is taken out.

The container body 1 is not limited to a plane formed in a rectangular shape, but may be applied in the same shape to a plane formed of a square or other polygon, or a circle or an ellipse.

In the above-described embodiment, the case where the instant food needs to be drained like a fried noodle is described. However, in the case of the instant food that does not require boiling, a bowl 8 is formed in the container body 1. Not to mention the needless to do.

According to the present invention, since the adhesive force to the lids at the two protrusions on the flange upper surface of the container body is made stronger than the adhesive force at the other places except the protrusions, the lid is not opened too much in hot water pouring or hot water pouring. There is an advantage that only a predetermined amount of opening can be opened.
