Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a packaged rice ball, a method for producing the same, and a packaging material, and more specifically, a plate of seaweed is interposed between the outer packaging and the inner packaging material, and the inner packaging is An inverted triangular rice ball is packaged inside, and when you pull out the bottom end of the inner package that protrudes from the insertion hole at the bottom of the outer package, the surface of the rice ball is exposed and dried sheets of seaweed stick to it, making it crispy. The present invention relates to a packaged rice ball in which the seaweed-wrapped rice ball remains in the outer packaging, a manufacturing method thereof that allows for rational and automatic production, and packaging materials therefor.

(Prior art and its problems) A rice ball and a sheet of nori are separated and packaged using a packaging material, and just before eating, the packaging material is removed and the dried sheet nori is wrapped around the rice ball to complete a crispy seaweed-wrapped rice ball. has been tried many times.

Among them, as shown in Fig. 3, an inverted triangular rice ball 40 is double-layered with an inner bag 42 of the same shape with an open top and an outer bag 46 with an insertion hole 44 in the bottom and the other part sealed. A plate of seaweed 48 is interposed between both bags, and the lower bottom part 50 of the inner bag is wrapped in the outer bag 4.
When eating the rice ball, the lower bottom part 50 of the inner bag 42 is pulled downward to bring the plate nori 48 into close contact with the rice ball, and the bonito onigiri 40 is pulled downward together with the inner bag 42. There is a packaged rice ball in which the rice ball is compressed from the outside by the taper of the outer bag 46 by the applied force, so that the crispy seaweed-wrapped rice ball with a firm shape can be eaten hygienically.

This packaged rice ball is excellent in that it can be completed as it is with a single touch operation by pulling out the protrusion of the inner bag.

However, the above-mentioned packaging material is made by cutting two sheets and molding it into a flat bag, and it requires the work of inserting the rice balls into the inner bag and the work of inserting the rice balls wrapped inside into the outer bag. It is difficult to do this manually, and a funnel-shaped auxiliary tool is used to open and insert bags, but this is not efficient and is particularly difficult to automate the cutting process.

In addition, if the seaweed is inserted into the inner wall of the outer bag in advance, the lower protrusion of the inner bag will catch the seaweed on the rough surface, making it difficult to protrude from the insertion hole of the outer bag. Therefore, wrap the seaweed around the inner bag. This makes the process very complicated.

(Objective) The object of the present invention is to provide a packaged rice ball that eliminates the above-mentioned drawbacks, makes it easy to insert the inner packaged rice ball into the outer bag, makes it extremely easy to automate the production, and reduces waste of packaging materials, and a method for producing the same. To provide packaging materials.

(Structure) The feature is that a rectangular sheet is folded in half around the vertical midline, and from a certain distance in the horizontal direction of the folded part on the lower edge, leaving an open part, the vertical mating end is folded in half. Fold the rectangular sheet in half around the vertical midline, leaving an open part in the horizontal direction of the folded part on the lower edge. From a certain distance away, seal in a spot or line along a line that rises diagonally toward the vertical mating edge, then open the bag in half and insert the bottom seal into a bag with an insertion hole in the bottom. A rectangular sheet is formed by inserting a plate of seaweed that is almost the same shape as the rectangular shape of the sheet along the inner wall surface of the sheet so that both lower corners of the sheet nori overlap inside the sealed part of the bag. Fold in half around the vertical midline, and from a certain distance horizontally from the folded part of the lower edge leaving an open part, place a spot or a line along a line that rises diagonally towards the vertical mating edge. Seal it in a linear shape, fold it open, make the bottom seal part into a bag shape with an insertion hole at the bottom, and place a sheet of seaweed that is almost the same shape as the rectangle of the sheet along the inner wall surface of the sheet. Insert so that the bottom corners overlap inside the seal part of the bag,
Insert an inverted triangular rice ball wrapped inside the seaweed in this bag using an inner packaging material such as a sheet or bag, and insert the lower end of the inner packaging material through the insertion hole at the bottom of the bag. The upper part of the outer packaging sheet is made to protrude and is folded inwards and downwards together with the seaweed to wrap the rice ball.The sheet that is unwound from the take-up roll is fed upward in a half-folded state and cut horizontally at regular intervals. At the same time, on the cutting line, seal in a spot or line along a line that rises obliquely toward the vertical mating edge from a certain distance from a position leaving an open part in the horizontal direction of the folded part, and fold in half. When opened, the seal at the bottom is shaped like a bag with an insertion hole at the bottom, and a sheet of seaweed that is approximately the same shape as the rectangle of the sheet is placed along the inner wall surface of the sheet. Insert them so that they overlap on the inside of the part,
Insert an inverted triangular rice ball wrapped inside the seaweed of this bag using an inner packaging material such as a sheet or bag, and insert the lower end of the inner packaging material into the insertion hole at the bottom of the bag. At the point where the rice ball was wrapped by folding the upper part of the outer wrapping sheet together with the seaweed downward into the inner side of the sheet, the lower part was folded into a board along the inner wall of the bag-shaped sheet, which was approximately an inverted triangle and had an insertion hole at the bottom. An inverted triangular rice ball is wrapped in such a way that the seaweed is inserted all the way to the inner wall of the bag, and the lower end of the inner wrapping material is pulled downward to expose the rice ball. The sheet is inserted into the bag so that it protrudes from the insertion hole of the sheet, and the upper part of the sheet is folded inwards and downwards together with the seaweed to wrap the rice ball. Along the inside of the rectangular sheet,
Insert the sheet nori so that it reaches the inner wall of the bag,
An inverted triangular rice ball wrapped in such a way that the rice ball is exposed when the bottom end of the inner packaging material is pulled downward.
The inner packaging material is inserted into the bag so that the lower end thereof protrudes from the insertion hole of the bag, and the sheet is placed on a packaging table having an equilateral triangular recessed part slightly larger than the rice ball. Place the rice ball so that the top edge of the rice ball is located slightly below the bottom edge of the recessed part, turn the rice ball upward along with the bag part, press fit into the recessed part, and press both corners of the upper part of the sheet that has risen. The point is to fold it into the rice ball side and seal it.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIG. 1a, 10 is a rectangular sheet made of moisture-proof cellophane, for example, with a length ratio of about 2:1, and is placed vertically. Figure 1b is centered on the vertical median line A of this sheet 10.
Fold it in half as shown, and position 1 slightly moved horizontally from the folded part 12 that forms a loop at the bottom end.
4, the wire is cut along a line that rises obliquely toward the vertical mating edge 14'.

In FIG. 1c, 16 is a bag portion, and the sheet 10
When opened from side to side, it is shaped so that it protrudes slightly forward, centering on the joint 18 that is sealed along the wire.

Reference numeral 20 denotes an insertion hole provided at the bottom of the bag portion 16, which is open at the opening between the folded portion 12 and the position 14 slightly moved in the horizontal direction in FIG. 1b.

In Figure 1 d, 22 is a plate of seaweed, and sheet 1
When the sheet 10 is inserted into the bag 16 from above along the inner wall surface of the sheet 10, both lower corners of the sheet 10 are inserted into the bag 16.
6 and overlap at the joint portion 18 toward the front along the front inner wall of the bag portion 16 .

When this plate nori 22 is loaded onto the sheet 10, even if it is slightly shifted left and right, it is guided by the oblique bottom of the bag portion 16 and settled in a fixed position along the center line A.

24 is the cover tape for the adhesive part, and the lower edge extends slightly to the part where the adhesive is not attached.
It is designed to hold the upper edge of the plate nori 22.

In FIG. 1e, 26 is an inverted triangular rice ball, which is wrapped in an inner packaging material 28 such as a sheet or a bag. It is preferable that the upper end is open from the beginning so that when the lower end 29 of the inner packaging material 28 is pulled downward, the rice ball 26 is exposed. Alternatively, the upper edge of the inner wrapping material 28 may be cut open when being pulled out.

FIG. 1f shows a state in which a packaged rice ball is inserted into the bag portion 16, and the lower end 29 of the inner packaging material 28 is inserted into the insertion hole 20 at the bottom of the bag portion 16 and protrudes.

Here, the bag portion 16 bulges forward from the plane of the sheet 10 and is open at the top, making it easy to insert the rice balls, and since the height of the bag portion 16 is lower than that of a triangular case, it can be inserted through the bag portion 16. The distance to the hole 20 is short, and it is easy to aim and insert the lower end 28 of the inner packaging material into the insertion hole 20. Therefore, sheet 1
Even if a plate of seaweed is inserted in advance into the outer bag (outer packaging material) formed by melt-cutting a sheet of seaweed along the line R, the lower end 29 of the inner packaging material will prevent insertion due to the rough surface of the plate of seaweed. There is no chance of being hit.

Next, as shown in Fig. 1g, flip the rice ball upward along with the bag portion 16, peel off the cover tape 24, and
As shown in Figure h, wrapping the rice ball at both upper corners of the sheet 10 and pressing the adhesive part completes the wrapping of the rice ball.

Figure 2 shows a packaging stand, 30 is a clamping tool on the upper edge of the sheet that can be opened and closed, and a magnet 32 is attached to the corresponding part of the stand.
is buried, and the metal clamping tool 30 is attracted by this suction force.

Reference numeral 34 denotes a recessed fitting part, which has an equilateral triangular shape slightly larger than a rice ball, and is located directly below the clamping tool 30.

The upper edge of the sheet 10 loaded with rice balls packed inside the bag part 16 is held by the clamping tool 30, and the rice balls 2 are placed in an inverted triangular shape directly under the recessed fitting part 34.
6 is flipped upward so that it overlaps the concave corner fitting part 34 together with the bag part 16, and is press-fitted into the concave fitting part 34, and the sheet 10
Both upper end corners of the rice ball stand up, and these corner parts are folded into the rice ball side and sealed with the adhesive part.
Of course, this seal may also be sealed by pasting a separate sealing material.

Note that the sheet 10 is made from two rolls of flat film.
Supplied folded or in tubes or two
A folded film may be supplied, and this may be cut to size.

The joint 18 of the bag portion 16 is optimally formed by overlapping the sheets 10 and cutting them by welding along the wires, but if the sheets 10 are simply welded and sealed, the corners will stick together; It may be left as it is, or it may be joined discontinuously along the wire.
The key is to have a pocket that accepts rice balls.

(Effects of the Invention) The rice ball according to the present application, which is configured as described above, has an insertion hole 2 in the lower bottom of the bag portion 16 of the outer packaging material.
By pulling out the lower end 29 of the inner wrapping material protruding from the inner wrapping material downward, the dried plate nori interposed between the inner wrapping material and the outer wrapping material is wrapped around the surface of the rice ball and the lower end of the inner wrapping material is pulled out. As the rice ball moves, the rice ball is pressed against the tapered part of the bag part 16 of the outer packaging material, and the shape is firmed, and the sheet nori is surely stuck to the surface of the rice ball.

In particular, since the packaging material according to this application uses a rectangular sheet, there is no wastage of material, and since the bag portion 16 bulges forward and the upper part is open, it is easy to insert sheet nori or inner wrapped rice balls. , bag part 16
Since the lower bottom part of the rice ball is tapered, no deviation occurs to the left or right when inserting the plate of seaweed, and as described above, the formation of the rice ball and the adhesion of the seaweed are ensured.

In addition, since the bag portion 16 is shallower than an ordinary triangular shape, the lower end 29 of the inner packaging material easily protrudes from the insertion hole 20 at the bottom of the bag portion 16, even if the diameter of the insertion hole 20 is made small. Since the lower end portion 29 can be inserted through the hole, reducing the diameter of the hole brings about significant effects such as preventing the rice grains from being pulled out together with the inner packaging material.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
