[Problem that the idea aims to solve]

Conventional single layer molded synthetic resin cups and resin laminated paper cups. The container became hot due to the temperature of the product, and if you touched the container with your hand, it was dangerous to get burned. Also, Insu In the case of tan ramen cups, single-layered noodles are used because they form uneven vertical ribs. Although it has some insulation properties compared to the type, it has poor heat retention and has a clean surface on the outside of the container. The problem is that it cannot be designed. Also, there is no lid material that can be heated in the microwave. I can't cook because of this. The one published in Utility Model Publication No. 62-130012 has a double container, but it is also electrically powered. It is not possible to cook because there is no lid material that can be heated in a small microwave. Therefore, the main idea is to keep warm. The purpose is to provide a container for microwave ovens that has excellent heat and heat insulation properties.

【Example】

A detailed explanation will be given below based on the drawings. Figures 1 and 2 are front views of the inner container (1) As shown in plan view, a plurality of vertical uneven ribs (2) are formed on the body of this container. (3 ) is a flange formed on the upper edge of the body. Figures 3 and 4 are front views of the outer container (4) In the plan view, a plurality of ribs (5) protruding inward are formed around the upper part of the body. There is. In the figure (6) is a flange. This rib (5) is the uneven rib of the inner container (1). It fits into the recess (2) and into the outer container (4). This provides double coverage inside and outside. form a top container and stop the rotational movement of the inner container in the left and right direction. Inside and outside as above Cup containers are made of synthetic resin or paper with resin laminated on both sides. Therefore, the depth and height of the uneven shape of the rib (2) becomes the distance dimension from the outer container. deer When fitted together, the flange (3) of the inner container (1) is connected to the flange (6) of the outer container (4). ), the flange (3) is tightened as shown in Figure 6, and the inner container (1) is attached to the outer container (4). ) It becomes more stable and does not come off easily. Figure 7 shows the inner container (1) and the outer container. (4) After mating, the flange of the inner container is shown tightened. For this reason, the flange (3) of the inner container (1) is larger than the flange (6) of the outer container (4). It is large in size.

[0008] The lip of the double cup container formed as described above is sealed with a lid material, but the inside The surface side is an easy-peel sealant (7) and the outside is a heat-resistant oleph. It is composed of an in-based or styrene-based film (9), and is edible when heated in a microwave oven. A large number of fine holes (8) are provided to dissipate moisture in the product. The first scenario as described above When laminating a secondary seal lid material on top of the seal lid material as shown in Figure 9, The sealant material (10) always has a higher sealing strength (peel strength) than the primary sealant material (7). degree) is required to be weak. For example, the sealing strength of the secondary sealant material (10) is 0.5kgf to 1.0kgf, the sealing strength of the primary sealant material (9) is approximately 1.5 kgf to 2.5 kgf. Note that (11) is the second This is a heat-resistant film used as a seal lid material.

[0009] By configuring as above, the secondary seal lid material can prevent secondary contamination. , and the primary seal lid material prevents a small amount of water vapor generated when heating food in a microwave oven. Dissipating through the thin hole (8), pressurizing the inside and causing the lid material to burst. There isn't.

0010 The one shown in Fig. 10 has a stepped portion (13) on the inner container (1) and a primary seal is attached to this. Attach the lid materials (7) and (9), and attach the secondary seal lid material (10) at a distance (12) from this. ) (11) is shown. With this configuration, the primary Two-stage sealing is possible without laminating the main seal material and the second seal material. The material composition of the sealing lid material and the secondary sealing lid material can be made of the same material, and the gap (12) The product can be preserved by adding oxygen scavengers and antioxidants. In addition, in Figure 8 The primary seal lid material and the secondary seal lid material shown in Figure 9 are protruding from the flange. However, this functions as a knob when peeling.

[0011] The one shown in FIG. 11 shows a so-called in-mold container, and the inner container ( 32) and the outer container (33) are both made of synthetic resin or paper, The inner container (32) is formed by connecting both with a synthetic resin support (14). The ends (17) of the paper are joined at the recesses (15) and (16) of the support (14), and The paper end (18) of the outer container is connected to the recess (31) of the outer container (14). The pillars (14) are required in at least two places, thereby making it possible to A container is formed. In addition, (19) is the inner container (32) that is integrated with the support (14). Shows the flange. Therefore, the flange portion is attached to the primary sealing lid material or the secondary sealing material. Of course, the lid material may be used as necessary. In any case, Figures 7 and 11 , 12 has a certain distance between the inner and outer containers by ribs, which provides heat retention. The insulation properties are maintained.

0012 Figures 13 and 14 show the packaging form when using the above-mentioned double container. Pillow-packed dry food such as fruit granules, jams, sauces, etc. (23) - The one attached to the cap (21) and the one attached to the cap (21) should be wrapped with polyethylene film etc. for hygiene reasons. It is shown attached with a spoon (24) which is packaged in a package. Spoon (24 ), omit the vertical rib of the inner container by the size of a spoon, and attach the outer container. A part of the protrusion (22) in (20) is also omitted, and a concave part (25) is provided in the omitted part. The spoon (24) is fitted into this, and the latch lid (24) integrally formed from the main body is removed. 6) Hold the spoon (24) from the outside with (27), and tighten its hooks (29) and (30). ) is fixed over the protrusion (34). Fixing the spoon is as follows. In addition to the stopper mechanism formed by injection molding techniques such as hot melt adhesive It can also be fixed by a method such as. By adopting the above packaging form, , commercialization of soup, ice cream heated in a microwave for a certain period of time to make it into a shake. Then top with the included pillow-wrapped strawberry sauce or pulp, or mix together. It becomes possible to develop edible products and apply it to viscous foods (cheese fondue, etc.) .
