Description

Food container set

The present invention relates to a food container set for enclosing food such as instant food in a container main body and pouring hot water into the container main body to replenish the food when eating.

Traditionally, instant foods with dried noodles, dried rice, etc. enclosed in the container body contain oysters, soup, etc. along with dried noodles, dried rice, etc. Cutlery was sometimes folded and stowed.

However, when there was no place to place the cutlery, it was cumbersome to hold the cutlery by hand and to open the bags such as oysters and soup, or to pour hot water. In addition, after pouring hot water, it is necessary to wait for several minutes until the noodles are loosened, but during that time, part of the lid peels off due to the heat of the hot water, and the heat escapes, and the heat retention is not sufficient.

Therefore, in recent years, a double container in which an inner lid is supported at the opening of the container body containing food and a dining tool or seasoning is placed in the inner lid and sealed with the lid has been studied. (Patent Document 1). This container is hygienic because food, quick seasonings, cutlery and the like (hereinafter sometimes simply referred to as “cutlery etc.”) are separately stored.

In addition, in the case of a normal flat lid (often made of paper), the lid may warp when the hot water is added, and the heat retention may decrease. However, when using the inner lid, the inner lid is a container. Since it is in a state of being fitted in the main body, it is difficult to peel off and has good heat retention.

However, when the inner lid is not properly supported by the container body, such as when the inner lid is not properly molded or the inner lid is tilted, distortion is concentrated on a part of the inner lid. Will cause dents. As a result, there is a problem in that steam leaks from the dent and the heat retention as expected cannot be realized.

Furthermore, when the inner lid is used, the distance between the hot water water line and the bottom surface of the inner lid is reduced, and the space in which the hot water can move (head space) becomes smaller. As a result, there has been a problem that the hot water leaks from the dent only by applying a small vibration when the hot water is added and transferred.

An object of the present invention is a food that can be easily opened and closed, and can maintain the sealed state of the container main body even when the inner lid is not properly supported by the container main body, and is difficult to leak steam and hot water An object is to provide a container set.

The food container set of the present invention comprises a container main body having an opening and an inner lid that is detachably supported by the container main body, and is provided with a gripping protrusion that can be gripped on the bottom surface of the inner lid. It is a feature.

According to the present invention, the inner lid is supported by the opening of the container main body for storing food (immediate noodles, rice, etc.), and the cutlery and the like can be placed in the inner lid, so that the food and the cutlery are in contact with each other. It is hygienic. Furthermore, since the opening can be closed with the inner lid after pouring hot water into the food in the container main body, the container main body is sealed to prevent steam leakage and hot water leakage during transfer.

Furthermore, the inner lid of the present invention preferably contains one or more resins selected from the group consisting of polyolefin resins, polyester resins and polystyrene resins. Since these resins have higher flexibility than a paper inner lid or the like, a small distortion generated between the container main body and the inner lid can be alleviated to improve the sealing performance.

Among these resins, polyolefin resins are preferable from the viewpoint of flexibility, moldability and durability, and specific examples of polyolefin resins include polyethylene resin (PE) and polypropylene resin (PP). In view of durability, it is more preferable to use a polypropylene resin as a main component (50% by weight or more).

In addition to the resin, talc, calcium carbonate, plasticizer, wax, antistatic agent, etc. may be added to the inner lid as needed. Moreover, there is no restriction | limiting in particular in the manufacturing method of an inner lid, It can manufacture by pressure-air forming, vacuum forming, injection molding, etc.

In the present invention, a gripping protrusion is provided on the bottom surface of the inner lid. When cooking, if you open the lid and pinch and lift the protrusion on the inner lid, you can inject hot water into the container body without having to remove the cutlery individually. Thus, the inner lid can be easily returned to the container body. Furthermore, if the inner lid is covered after pouring hot water into the container body, water droplets may accumulate in the gap between the container body and the inner lid, making it difficult to open and close, but in the present invention, a gripping projection is provided. Easy to open and close.

The gripping protrusion is not particularly limited as long as it is suitable for opening the inner lid. However, in consideration of the ease of opening the inner lid, it is preferable to provide a gripping projection having a height of 7 mm or more and a width (diameter) of 5 mm or more at the center.

In the food container set of one aspect of the present invention, it is preferable that the entire peripheral surface or the lower part of the inner lid is formed in a semi-cylindrical shape. By molding the whole or lower part of the peripheral surface into a semi-cylindrical shape, the rigidity of the entire inner lid is increased, and the strain can be distributed over the entire peripheral surface. And the local small distortion disperse | distributed to the whole surrounding surface is relieve | moderated by the softness | flexibility of polyolefin resin. For this reason, the airtightness of the whole food container set is enhanced, and it is difficult for a large dent to leak steam or hot water.

In the food container set according to one aspect of the present invention, when the lower peripheral surface of the inner lid is molded in a semi-cylindrical shape, the upper peripheral surface is molded into a tapered shape that is inclined outward, and the upper upper peripheral surface of the inner lid The taper angle is preferably equal to or larger than the taper angle of the peripheral surface of the container body.

When the upper peripheral surface of the inner lid is molded into a taper shape, the upper peripheral surface of the inner lid protrudes from the lower peripheral surface. At this time, the upper peripheral surface of the inner lid functions like a “plate spring” and is pressed against the container body. For this reason, the inner lid is firmly fixed, and it is possible to prevent a trouble that the inner lid comes off due to vibration or the like during transfer.

It is a perspective view of the inner lid by which the whole surrounding surface is shape | molded by the semi-cylinder shape. It is sectional drawing of the inner lid shown in FIG. FIG. 3 is a perspective view of an inner lid in which a lower peripheral surface is formed in a semi-cylindrical shape and an upper part is formed in a tapered shape. FIG. 4 is a cross-sectional view of the inner lid shown in FIG. 3. It is a perspective view of an inner lid in which the entire peripheral surface is formed in a semi-cylindrical shape and a gripping protrusion is provided on the bottom surface. FIG. 6 is a cross-sectional view of the inner lid shown in FIG. 5. FIG. 4 is a perspective view of an inner lid in which a lower peripheral surface is formed in a semi-cylindrical shape, an upper portion is formed in a tapered shape, and a gripping protrusion is provided on a bottom surface portion. FIG. 5 is a perspective view of an inner lid provided with a gripping protrusion and a stacking convex portion that are molded in a semi-cylindrical shape at a lower peripheral surface and a tapered shape at an upper portion and can be gripped on a bottom surface portion. FIG. 9 is a top view of the inner lid shown in FIG. 8. It is a side view of the inner lid shown in FIG. It is the figure which compared the taper angle of the peripheral surface upper part of the inner lid, and the container main body.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. In addition, the same referential mark is attached | subjected to the element which is the same or it corresponds through all the following figures, The duplication description may be abbreviate | omitted.

FIG. 1 is a perspective view of an inner lid 10 whose entire peripheral surface is molded in a semi-cylindrical shape. By molding the peripheral surface 11 of the inner lid into a semi-cylindrical shape that protrudes outward, the peripheral surface 11 functions like a packing, and the hermeticity of the container set can be enhanced. Moreover, since the inner lid 10 is supported by the container body 1, it can store cutlery and the like.

As described above, by molding the entire peripheral surface 11 into a semi-cylindrical shape, the rigidity of the entire inner lid is increased, and the strain can be distributed over the entire peripheral surface. And since the local small distortion disperse | distributed to the whole surrounding surface is relieve | moderated by the softness | flexibility of polyolefin resin, even if there is some distortion and the blur of a dimension in the container main body 1 or the inner lid 10, There is no loss of sealing.

2 is a cross-sectional view of the inner lid 10 shown in FIG. 1. FIG. 2 (a) is an example in which the peripheral surface 11 is formed into a curved half cylinder, and FIG. It is an example molded into a trapezoid. Since the inner lid 10 of the present invention is highly flexible, when the inner lid 10 is supported by the container body 1, the peripheral surface 11 is slightly deformed by its own weight. For this reason, the shape of the peripheral surface 11 has a high degree of freedom, and only needs to be a semi-cylindrical shape protruding from the edge of the bottom surface 14 of the inner lid 10.

FIG. 3 is a perspective view of the inner lid in which the lower peripheral surface 12 is formed in a semi-cylindrical shape and the upper peripheral surface 13 is formed in a tapered shape, and FIG. 4 is a cross-sectional view thereof. The holdability of the inner lid 10 can be improved by molding the lower circumferential surface 12 into a semi-cylindrical shape and the upper circumferential surface 13 into a tapered shape. Further, since the cutlery and the like naturally slide down along the taper surface during storage, the storage efficiency of the cutlery and the like is increased.

FIG. 5 is a perspective view of the inner lid 10 in which the entire peripheral surface 11 is formed in a semi-cylindrical shape and the gripping protrusion 15 is provided on the bottom surface portion 14, and FIG. 6 is a sectional view thereof. is there. If hot water is poured into the container body and the inner lid is covered, water droplets accumulate in the gap between the container body 1 and the inner lid 10 and may be difficult to open and close. In view of this, a gripping protrusion 15 is provided at approximately the center of the inner lid 10 to facilitate opening and closing.

The shape and size of the protrusion 15 are not particularly limited, but considering the ease of gripping, the height is preferably 7 mm or more and the width (diameter) is 5 mm or more.

FIG. 7 is a perspective view of the inner lid in which the lower peripheral surface 12 is formed in a semi-cylindrical shape, the upper peripheral surface 13 is formed in a taper shape, and a gripping projection 15 is provided on the bottom surface portion 14. . Although the characteristics of each component are as described above, it is more preferable because it can simultaneously realize hermeticity, storage properties such as cutlery, and ease of opening and closing.

In FIG. 8, the lower peripheral surface 12 is formed into a semi-cylindrical shape, the upper peripheral surface 13 is formed into a taper shape, and a holding projection 15 that can be gripped on the bottom surface portion 14 and a stacking convex portion 16 are provided. 2 is a perspective view of an inner lid 10. FIG. By providing the stacking convex portion 16, a plurality of inner lids 10 can be compactly stacked (stacked), and the cutlery or the like becomes difficult to move, and troubles such as breakage during transportation can be prevented. .

In addition, in FIG. 8, although the three convex parts which contact | connect a bottom face part and a peripheral surface part are provided, it is not limited to this aspect. For example, the same function can be achieved by providing the stacking convex portion 16 at any one position of the bottom surface portion and not in contact with the peripheral surface portion.

FIG. 8 also illustrates the container body 1. The container body is made of, for example, paper (including water-resistant paper with polyethylene or the like loaded on the surface), and includes a circular bottom surface portion and an inverted frustoconical peripheral surface portion 2 formed around the circular bottom surface portion. The peripheral surface portion is formed in a tapered shape that is inclined outward from the bottom surface portion toward the opening portion. And the flange part 3 extended in radial direction outer side is formed in the opening part in the ring shape. The container body may be formed of a synthetic resin, for example, made of polypropylene or polyethylene, and may be manufactured by pressure forming, vacuum forming, injection molding, or the like.

9 is a top view of the inner lid shown in FIG. 8, and FIG. 10 is a side view of the inner lid shown in FIG.

11 shows a taper angle 21 (hereinafter referred to as “inner lid taper angle 21”) at the upper peripheral surface of the inner lid and a taper angle 22 (hereinafter referred to as “main body taper angle 21”) of the peripheral surface portion of the container body. FIG. The inner lid taper angle 21 is preferably equal to or larger than the main body taper angle 22. When the inner lid taper angle 21 is smaller than the main body taper angle 22, a gap is formed between the inner lid and the container main body, which may reduce the holding efficiency of the inner lid and the storage efficiency such as cutlery. is there.

On the other hand, if the inner lid taper angle 21 is too larger than the main body taper angle 22, the inner lid may be distorted and a cavity may be formed between the container main body and the inner lid. In this case, by adjusting the length of the upper circumferential surface 13 and the softness of the material, the distortion of the inner lid can be alleviated and the generation of cavities can be suppressed.
