Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an improvement in a method for manufacturing packaged confectionery, in which an airtight packaging material is formed into a container shape, and a confectionery material heated to high temperature is filled and sealed.

Conventional technology As disclosed in Japanese Patent Publication No. 55-51526, a method for producing packaged confectionery involves forming pleats around the periphery of a packaging material made by bonding outer wrapping paper to tin foil, and using a bottomed cylinder with an open top surface. The first step is to form the body, and the cylindrical body is placed in a mold with the opening facing upward, and a fixed amount of confectionery material heated to a high temperature is filled into the mold.After the high temperature confectionery material is cooled and solidified, the cylindrical body is formed. A packaged confectionery product consisting of a second step of folding the pleats around the opening toward the center, closing the opening, and adhering a sticker paper over it, and a third step of heat-treating the sticker paper with the adhesive side facing down. This is the manufacturing method.

Problems to be Solved by the Invention The method for producing packaged confectionery described above has the disadvantage that equipment for solidifying the filled confectionery material is required.

That is, in order to solidify the confectionery material filled in the cylinder and heated at a high temperature of around 90° C. during the second step, a cooling facility is required.

The reason is that natural cooling at room temperature takes a long time before the next sealing process. In the cooling device used in the conventional method for manufacturing packaged confectionery, a cooling conveyor is provided in the cooling chamber for passing the open cylindrical body of the filler, and the speed of the conveyor is 2.8 meters per minute. The effective length of the cooling conveyor was approximately 84 meters, the cooling time was approximately 30 minutes, and the cooling equipment required a large area within the confectionery factory. In addition, since the cylindrical body is moved with its opening on the cooling conveyor, great care must be taken to ensure that there are no falling bacteria or foreign objects during the movement, so the cooling system is large and expensive. It had the disadvantage of being expensive. Furthermore, after the confectionery material inside the cylinder is cooled and solidified, it is transferred to a room temperature room, the opening is folded and closed, and a seal paper is pasted on top of it to seal it. There is also a possibility that the intrusion of water may become a source of mold, etc. For this purpose, a sticker paper is pasted to seal the package, and the package is then placed on a hot plate with the seal side facing down and heated to sterilize the package, which is said to be a sanitary process. .

Means for Solving the Problems It is an object of the present invention to provide a method for economically and efficiently producing packaged confectionery that can be stored for a long period of time by improving the drawbacks of the conventional production method.

The method for manufacturing packaged confectionery of the present invention includes a first step of forming an airtight packaging material that blocks light and air, such as aluminum foil or tin foil, into a cylindrical container with a bottom and placing it in a mold; A cylindrical container placed in a mold is filled with heated confectionery ingredients in a fixed quantity.
A lid formed from the same kind of material as the packaging material is placed over the top surface of the confectionery material filled with a fixed amount and pressed against it, tilting the periphery of the cylindrical container inward and pressing it,
The second step is to affix a label thereon and seal it.

Thus, in the present invention, an airtight packaging material is formed into a cylindrical container with a bottom, placed in a mold, and a viscous confectionery material heated to high temperature is filled into the cylindrical container. Cover the top of the quantitatively filled confectionery material with the lid, press it so that the top surface is flat, and fold the cylindrical container by folding the periphery of the container inward.
The top surface is pressed and a label is attached and sealed to complete the packaged confectionery.

Examples This invention will be explained with reference to the drawings. FIG. 1A shows a bottomed cylindrical container 1 made of an airtight material and formed into a cup shape with pleated edges, and is open at the top. This container 1 is molded using, for example, a processing jig disclosed in Japanese Patent Publication No. 49-8310 filed by the present applicant, and placed in a ring-shaped mold 2 shown in FIG.

Conventionally, in the manufacturing method of packaged confectionery, the inclined part of the periphery is concentrated in the direction of the center with respect to the thickness of the filling material (confectionery material) placed in the container 1. However, in this invention, in order to accommodate the lid part 3, only a height of about 1/3 or 1/4 of the diameter of the container 1 is required.

After the first step of placing the cylindrically formed container 1 into a ring-shaped mold 2, the container 1 is filled with a viscous confectionery material heated to around 90°C. 4 was filled in a fixed amount as shown in FIG. 2B, and the top surface of the filled container was covered with the lid 3 shown in FIG. , the upper surface of the lid part 3 is pressed with a disc or the like so that it becomes flat, the space inside the filling is eliminated, and the outer periphery of the edge 3' of the lid part 3 is in contact with the inner side of the edge 1'. Next, as shown in FIG. As shown in FIG. 5, when the folded edge 1' is tilted toward the center and pressed so as to touch the top surface of the lid part 3, the top surface becomes flat as shown in FIG. 5, and the label 5 shown in FIG. 6 is pasted on top of it. It consists of a second step of removing from the mold 2, and a finished packaged confectionery product 10 shown in FIG. 7 is completed. 8th
The figure shows the label 5 with its pasted side facing down.
The finished product 10 of the packaged confectionery usually has the bottom surface as the surface to which the label 5 is attached.

This invention replaces the conventional three-step manufacturing method for packaged confectionery with two steps, the container can be made using conventionally known materials including the lid, and the high-temperature filling material 4 is added immediately after the lid is closed. The inside of the container is heated and sterilized by covering the part 3 and folding and sealing it without creating a gap, and the filling 4 is isolated from the outside air and made airtight, thereby completing a packaged confectionery that can be stored for a long time. This sealed packaged finished product 10 is normally left to cool in a room at room temperature, but may be left to cool if necessary.

In this invention, an embodiment in which viscous confectionery material is filled and sealed is shown, but the present invention is not limited to sealed packaging for confectionery as it can also be applied to foods other than confectionery.

Figure 9 shows another embodiment with a different shape, in which the packaging material is formed into cup-shaped containers of the respective types and placed in a mold that fits the container, and confectionery, food, etc. are heated to high temperatures. A sealed package having the shape as shown in the figure is completed by filling a fixed quantity of the materials, covering the top with a lid of each shape, and then pulling out the label 5 from the pasting form. Figure A shows a hexagonal shape, Figure B shows a square shape, Figure C shows an oval shape, Figure D has each side curved to form an almost triangular or rice-grip shape, and the rectangular package shown in Figure B does not have folds formed on the sides. Figure C shows an example of fold-forming, and in Figure C, the packaging form is such that there are no pleats on both sides.

Effects of the Invention In the method for producing packaged confectionery according to the present invention, the first step and the second step are connected and made continuous, so that container forming, quantitative high-temperature filling, lid covering, folding and labeling are possible. This synchronization simplifies the work method and makes the production of packaged confectionery more efficient.

In the conventional high-temperature filling of kneaded confectionery, the manufacturing process takes a lot of time and requires cooling equipment, as it is sealed and packaged after being cooled and solidified. By sealing, the inside of the container is heat sterilized, and a sealed packaged product can be completed in less time during the manufacturing process. The hermetically sealed packaged product of this invention has hygienic effects that can withstand long-term storage, eliminates the need for forced cooling equipment with a large area, and sterilization equipment after labeling, reducing the work area.
Effects such as reduction in power costs by shortening the process and efficient allocation of workers can be obtained.
