Description

[Detailed description of the invention] (Field of industrial application) The invention is a packaging sheet for triangular rice balls in which a sheet food such as seaweed is sandwiched between an inner film and an outer film. This relates to a packaging sheet in which a sheet food directly covers a rice ball.

(Prior art and its problems) Conventionally, as shown in FIG. 6, triangular rice balls are packaged using a triangular packaging bag in which a sheet food 3 is housed between a triangular outer bag 1 and a triangular inner bag 2. things are being done.

When one end 23 of the inner bag 2 protruding from the lower end of the outer bag 1 is pulled and the inner bag is removed, the sheet-like food 3 is removed.
directly covers the rice ball 4, and if the outer bag 1 is opened, it can be eaten as is.

In the case of the above-mentioned packaged rice ball, the inner bag 2 is made of a material that easily slips against the cooked rice, and the rice ball is coated with cooking oil to make it slide better with the inner bag 2, but the outer bag 1 is Because the inner bag was wrapped tightly, there was a lot of resistance when the inner bag was pulled out, and the end of the inner bag could be torn off, leaving the inner bag inside the package.

Furthermore, the triangular packaging bag has an outer bag and an inner bag that are separately formed into triangular shapes, and the outer bag is filled with seaweed folded into a triangular shape.
Furthermore, an inner bag had to be inserted, which increased the manufacturing cost of the packaging bag.

Furthermore, in order to package the rice balls in the triangular packaging bag, it is necessary to inflate the opening of the bag and insert the rice balls, making it difficult to automate the packaging and requiring manual labor. Poor work efficiency
This also increased the manufacturing cost of the packaged rice balls.

There is also known a packaged rice ball in which a triangular rice ball is wrapped in a rectangular packaging sheet containing seaweed between double films, and when eaten, the wrapping is removed, the seaweed is taken out from between the films, and the rice ball is wrapped by oneself.

The automatic packaging device for packaging rice balls in the above-mentioned rectangular packaging sheet is the device previously proposed by the applicant (Japanese Patent Publication No. 61-22937), which has been put into practical use, and has high manufacturing efficiency, and the manufacturing cost of the wrapped rice balls is lower than that of the triangular packaging sheet. This can be significantly reduced compared to using bags.

However, when rice balls are wrapped in a rectangular packaging sheet, you have to wrap the nori around the rice ball yourself after removing the packaging. There is no convenience.

(Means for solving the problem) The present invention is capable of automatic packaging, and instead of pulling out the entire inner bag at once like in the past, it first pulls out half of the inner film, which has been divided into two parts, and wraps the seaweed. The present invention discloses a packaging sheet capable of bringing a sheet-shaped food such as the above into contact with one side of the rice ball, and then covering the remaining one side of the rice ball with the sheet-shaped food when the rice ball is removed from the outer film.

The present invention is a rice ball packaging sheet in which a sheet-like food product 3 is sandwiched between an outer film 1 and an inner film 2. The outer film 1 is formed by cutting diagonally both sides of one end of a rectangular film. A tear strip 12 that separably connects the outer film 1 at the center is formed in the width direction of the outer film. Inner film 2
The drawer piece 23 is formed to a size that overlaps the outer film 1 and projects from the cut side end of the outer film 1, and the inner film is attached to the opening strip 12.
The film is separated into two films 2a and 2b in the vicinity of .

(action and effect) First, the packaging procedure for rice balls will be explained.

As shown in FIG. 4a, a packaging sheet is placed horizontally with the inner film 2 facing down below the packaging turntable 5, which has a mold hole 51 that is slightly larger than the outline of the triangular rice ball 4. The rice balls 4 are placed toward one end and placed below the packaging sheet in accordance with the direction of the mold holes 51.

At this time, the unsealing strip 12 of the packaging sheet and one side edge of the rice ball are aligned in parallel.

Next, the rice ball is pushed up and passed through the mold hole 51 of the turntable 5 together with the packaging sheet, and the sheet is shaped into the rice ball 4 by the edge of the mold hole.
Fold it downward along three sides 41, 42, 42 (Figure 4b).

At this time, the top surface and three sides of the rice ball are wrapped at once by the folded pieces S ₂ , S ₃ , and S ₃ of the sheet.

At this point, move the rice ball horizontally to the bottom side of the triangular rice ball as indicated by the arrow P, hang the folded piece _S2 hanging from the bottom over the edge of the mold hole 51, and fold it toward the bottom side of the triangular rice ball (Fig. 4). c).

Fold one end of the rectangular folded piece _S2 upward along the two sides of the rice ball 4 (Figure 4d).

The pull-out piece 23 of the inner film 2 protrudes from the outer film 1 at the top position of the rice ball.

The edges S ₄ and S ₅ of the sheet protruding above the top surface of the rice ball 4 are folded over the rice ball, and the overlapping portions are heat welded S ₆ (Fig. 4e).

The rice balls are packaged according to the above steps.

The sheet food 3 has an inner film 2 and an outer film 1.
It is sandwiched between the rice balls, does not come into direct contact with the rice balls, and
Since it is shielded from the outside air, moisture is prevented (Figure 5).

When eating rice balls, pull out the drawer piece 23 and remove the inner film 2 consisting of two films.
Pull out the film 2a on the drawer piece 23 side (fifth
figure).

The film is only weakly heat-welded to the outer film 1 in spots, so if you grab the bottom of both inclined sides of the rice ball with one hand and pull the drawer piece 23 with the other hand, the drawer will slide out. It can be easily pulled out without any significant resistance and without breaking midway.

When the half 2a of the inner film 1 is pulled out as described above, half of the sheet-like food directly covers one side of the rice ball.

Next, the opening strip 12 of the outer film 1 is opened, and the upper part of the packaged rice ball is grasped with the opening section facing down.

Insert your fingers between the outer film 1 and the sheet food 3 from both sides of the rice ball, lightly pinch the rice ball, and pull out the rice ball (Figure 5c).

At this time, half of the inner film 2 that remained inside the outer film 1 is folded together with the outer film 1 to the oblique side of the rice ball, so it remains together with the outer film 1, and the rice ball and sheet food are The food sheet 3 is pulled out by crossing the inner film 2a, and at this time, half of the sheet-like food 3 covers the rice ball, and is pulled out from the outer film 1 as it is, so that the triangular rice ball covered with the food sheet can be eaten.

The rectangular packaging sheet of the present invention can be automatically wrapped using an automatic packaging machine in the same way as conventional packaging sheets, and it can also be wrapped by forming two inner and outer films into a triangular bag, like conventional triangular packaging bags. The manufacturing procedure of the packaging sheet is simpler than that in which the triangularly folded sheet food 3 is sandwiched therein, and the cost of the packaging sheet itself can be reduced.

(Example) The outer film 1 is a rectangular film with a length of 220 mm and a width of 140 mm, with one end and both sides cut diagonally to have a trapezoidal end.

As shown in FIG. 2, the outer film 1 has a tear strip 12 formed by adhering a narrow tape 13 along the entire length of the outer film 1 in the width direction at a position approximately 95 mm away from the end of the trapezoid. .

When one end of the tape is pulled, the film at the tape adhesive part adheres to the tape and is torn into strips, dividing the outer film 1 into two.

Sheet-like foods such as seaweed 3 are more 1 than the outer film.
The circumference is small, and one end is cut into a trapezoidal shape corresponding to the trapezoidal end of the outer film.

The inner film 2 is placed over the sheet-like food 3.

The inner film 2 is formed in the same shape as the outer film 1, but a portion corresponding to the trapezoidal end of the outer film is formed longer than the outer film and protrudes from the outer film, and the protrusion portion is connected to the pull-out piece 23. Become. Furthermore, the inner film 2 is divided into two parts at a position approximately 145 mm from the trapezoidal tip of the film.

Spot heat welding 10 is applied to an outer film 1 and an inner film 2 surrounding the outer periphery of a sheet-like food product 3.

The triangular rice balls are then packaged using the packaging sheet as shown in FIG. 4 and described above.

When eating the rice ball, pull out the pull-out piece 23 and pull out the film 2a on the pull-out piece 23 side of the inner film consisting of the two films 2a and 2b.

The film is only weakly heat-welded to the outer film 1 in spots, so if you grab the bottom of both inclined sides of the rice ball with one hand and pull the drawer piece 23 with the other hand, the drawer will slide out. It can be easily pulled out without any significant resistance and without breaking midway.

When the half 2a of the inner film 2 is pulled out as described above, the half of the sheet food 3 directly covers the rice ball.

Next, the opening strip 12 of the outer film 1 is opened, and the upper part of the packaged rice ball is grasped with the opening section facing down.

Insert your fingers between the outer film 1 and the sheet food 3 from both sides of the rice ball, lightly pinch the rice ball, and pull out the rice ball.

At this time, the half 2b of the inner film 2 remaining inside the outer film 1 is folded together with the outer film 1 to the oblique side of the rice ball, so it remains together with the outer film 1, and the rice ball and sheet-shaped food is pulled out across the inner film 2b, and at this time, half of the sheet-like food 3 covers the rice ball and comes out of the outer film 1 as it is, so that the triangular rice ball covered with the sheet-like food can be eaten.

The packaging sheet of the present invention can be automatically wrapped using an automatic packaging machine in the same way as conventional rectangular packaging sheets, and like conventional triangular packaging bags, the inner and outer films are formed into a triangular bag and a triangular Compared to the case of sandwiching folded sheet foods, the manufacturing procedure of the packaging sheet is simpler, and the cost of the packaging sheet itself can be lowered.

The present invention is not limited to the configuration of the above-described embodiments, and various modifications can be made within the scope of the claims for utility model registration.
