Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a container for food such as ice cream, frozen yogurt, yokan, etc., which retains its shape by freezing or hardening.

(Prior Art) Conventionally, the following method has been used to take out food that retains its shape by freezing or hardening using a large container in the same shape as the container.

The first method is to use a metal mold to fill the food inside, and after freezing and hardening, remove the food from the mold.

The second method is to fill a cup-shaped or cylindrical paper container with food, freeze and harden it, and then cut the paper container to remove the food inside.

A third method is to directly fill food into paper cartons, install a rigid outer container outside the carton to prevent deformation of the carton due to filling pressure, and remove the carton from the outer container after freeze-hardening. How to cut a carton and empty the contents.

A fourth method involves inserting a flexible inner container inside a rigid metal container, filling it with food, then hardening and freezing, and extracting the food inside the flexible container from the outer rigid container. This method involves cutting or peeling off the inner flexible container to obtain the same shaped food.

(Problems to be solved by the invention) In all of the above methods, food is filled into a container, the container is frozen in that state, solidified and kept in shape, and then it is subjected to various methods such as thawing and cutting. Therefore, the food contents were removed from the container and transferred to another container of the same shape, or the food was displayed in its original shape.

Each of the above methods has unresolved problems in workability, economy, hygiene, and versatility of shape.

That is, in the first method, the metal mold was expensive and the shape was limited to a forward tapered shape with no irregularities. Furthermore, if the food is frozen and hardened, thawing is required, which requires large equipment. In the second method, the paper cup itself lacks rigidity, and in the case of a rectangular shape, the body tends to expand outward due to the pressure of food filling. Therefore, it becomes difficult to maintain the desired shape of the food. Third
The methods range from paper carton assembly methods to freezing,
The shape of the food to be solidified is limited to a non-tapered block (rectangular parallelepiped).

Furthermore, if cardboard or the like is used for the outer container, it will have a heat insulating effect and will take a long time to freeze.

The fourth method uses a flexible container that is not self-supporting as the inner container, and therefore is not easy to work with.

(Means for Solving the Problems) Therefore, the technical problem of the present invention is to maintain the shape of the food inside a large container by freezing or hardening so that it has the same shape as the container and can be easily taken out. The purpose is to provide food containers.

The technical means of the present invention to solve this technical problem is to use a material in which a release material is laminated on a base material, and a large deep squeeze container with a flange is molded so that the release material is on the inner surface. This food container retains its shape by freezing or hardening, and is characterized in that two V-notches are formed on the flange in the direction toward the container body, spaced apart by a certain distance.

(Effect of the invention) According to this technical means, after the outer container is cut by two V-notches provided on the container flange, the gap between the outer base container and the inner container made of the release material is cut. The outer container can be easily removed from the inner container by causing delamination.

Since the inner container can be peeled off from the contents by utilizing its flexibility, it is possible to obtain food that retains the same shape as the container.

(Example) The embodiments shown in the drawings will be described below.

First, let's talk about the material of the container.The material used is mainly a laminated layer of plastic sheets and plastic films.

The thickness of the sheet as the base material 1 depends on the shape and capacity of the container, but for large square containers of about 4 to 5
Approximately 0.8mm to 1.2mm, inner layer film 2 is 80μ
Use a material with a thickness of ~100μ and excellent flexibility (see Figure 1).

The adhesive strength between the base sheet 1 and the inner layer film 2 is extremely weak compared to normal adhesive strength, and the adhesive strength is approximately 10 gf for a width of 15 mm. In other words, it is the strength that allows both to peel into the container (see Figure 2).

PS is suitable for the sheet 1 as the base material in terms of releasability and moldability, but PET, PE, and PP can also be used. PP and PE are suitable for the inner layer film, but depending on the purpose, PS, PVC, PET, EAV, etc. can also be used. Both can be laminated using a common co-pressing machine (see Fig. 3).

The container of the present invention is formed by vacuum forming or pressure forming using the above materials.

As shown in FIG. 1, the film is shaped so that the second side is always on the side of the food to be filled.

The container can be formed into any shape, including square, cylindrical, and oval. The capacity is relatively large 2-5
The container should be of a certain size.

For example, when the shape of the container is rectangular, the outer flange 4 of the container 3 is provided with a V-notch 5 facing the container body at a certain distance in the longitudinal direction of the flange 4, as shown in FIG.

The V-notch 5 is located close to the container corner 6, but if the container corner 6 is formed in a rounded shape, the V notch 5 is located close to the end of the rounded corner.

The V-notches 5 shown in FIG. 4 are provided on the flanges 4 on both opposing sides. The width of the flange is not particularly limited, but it is preferably about 15 mm to 20 mm so that it can be easily picked up with fingers. The depth of the V-notch should be approximately 10 mm (see Figure 5).

The container 3 as described above is filled with food such as ice cream, pudding, jelly, etc. using a pipe or the like as shown in FIG. Generally, it is suitable for foods that are filled in sol form and then frozen and solidified.

In either case, the container is filled with a food product that has the same physical properties as the container. After filling, cover with a paper or plastic molded lid 7 or the like. FIG. 7 shows the case with a paper lid, and FIG. 8 shows the lid with a molded plastic lid. In Figure 8,
The V-notch 5 is covered by the periphery of the lid 7.

FIG. 9 shows a film 2 made of release material with a tack label 8 partially adhered to the surface of the inner container 2', and is used to peel the inner container 2' from the outer container 1'. do.

In the illustrated example, a tack label 8 is provided at one location between the V-notches 5, and is also provided at the opposing flange portions.

As described above, after filling the container 3 with food, the lid 7 is closed to freeze and solidify the food.

In order to take out the solidified food in the same shape as the container from the container 3, the lid 7 is removed and the tack label 8 attached to the flange portion 4 is gently pulled up above the container as shown in FIG. Tatsukurabel 8
The adhesive strength of the inner film container 2' is about 300gf/15mm width, and the lamination strength between the inner film container 2' and the outer base material container 1' is 10gf/15mm width as mentioned above, so the inner container 2' is about 300gf/15mm width. It is pulled up from the flange portion 4 by the tack label 8 and easily peeled off from the outer container 1'.

Next, as shown in FIGS. 12 and 13, a pair of V-notches 5 provided on the flange 4 of the outer container 1',
By grasping the middle part of 5 and pulling it downward, the body of the outer container 1' will be torn into containers due to the nature of the V-notch 5 and the orientation of the plastic, allowing the outer container 1' to be removed. The same operation is performed again on the facing flanges, and the body of the outer container 1' is completely removed from the inner container 2', leaving only the side end surfaces of the outer container 1' on both sides of the inner film container 2'. It is possible to obtain the contents food a packaged in the following manner.

Next, the outer container 1' on both end faces is removed. Since the body of the outer container 1' has already been completely removed, the side portions of the outer container 1' can be easily removed from the inner container 1', as shown in FIG.

FIG. 16 shows the food packaged by the inner film container 2' after the outer container 1' has been removed.

To take out the food contents a from the inner container 2', pinch the tactile label 8 attached to the inner container 2' and push it down as shown in FIG. 17. If the inner container 2' is peeled off from the food a by rolling it up, the inner container 2' can be easily peeled off from the food a, and a large food having the same shape as the container 3 can be obtained as shown in FIG.

Next, by placing a display container 9 made of stainless steel or the like of the same shape over the food item a from above as shown in Figure 19, you can easily and hygienically transfer the large food item that was originally intended. It can be transferred to another container 9 of the same shape.

FIG. 20 shows the final state after the food contents a have been transferred to another container 9 of the same shape. As described above, the container is placed between the outer container 1' and the inner container 2' by the tack label 8 partially adhered to the inner container 2' or by pinching one side of the heat-sealed lid and pulling it upwards into the container 3. delamination occurs.

Next, the intermediate portions of the two V-notches 5, 5 of the outer container 1' provided on the flange 4 are grabbed and the container is pulled down at once to cut it, and the body of the outer container 1' is removed from the inner container 2'. Remove. Next, when the outer containers 1' remaining on both sides are removed from the inner containers 2', the food contents a packaged in the flexible inner containers 2' can be obtained.

Next, by removing the inner container 2' from the food product a using the flexibility of the inner container 2', the food product a having the same shape as the container 3 can be easily obtained.
It can be easily transferred to a display container 9 of the same shape.

In addition, since the outer container 1' and the inner container 2' of the present invention are integrally molded, compared to those that are not integrally molded, there is no wrinkles and the food a has the same shape as the outer container 1'. Furthermore, the food does not get stuck between the wrinkles during freezing, making it difficult to peel off the inner container 2' from the food a.
