Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a packaging material for rice balls made of a synthetic resin film and a method for producing the same.

[Prior Art] Onigiri sold at convenience stores and the like are usually wrapped in a transparent synthetic resin film, and the synthetic resin film is formed into a bag with a sheet of seaweed to be wrapped around the onigiri stored inside. ing.

This type of rice ball packaging material is opened by a cut tape etc. provided on the outside, and when the packaging material separated by the cut tape etc. is removed, the sheet-shaped nori stored inside is exposed and left as it is. Roll it into a rice ball (τ) so that it can be kicked (for example,
58, Utility Model Application Publication No. 82-GO5Ei5).

[Problems to be Solved by the Invention] However, the conventional packaging material for rice balls as described above is composed of one rectangular film serving as the outer surface and two half-sized films serving as the inner surface. The two inner films are overlapped at the center of the outer film without adhesive, and the periphery excluding the overlapping part is sealed to the periphery of the outer film to form a bag-shaped seaweed storage area. However, the opening side of cut tape, etc. must be placed on the outside of the outer film, facing the overlapping part. However, this method not only reduces work efficiency but also increases costs.

The present invention was made to solve these problems,
The object of the present invention is to provide a packaging material for rice balls that can be opened without the need for opening materials such as cut tape, and a method for manufacturing the packaging material for rice balls that can be easily manufactured with a small number of parts. .

[Means for Solving the Problems] As a means for technically solving the above-mentioned problems, the present invention has a non-adhesive overlapping part in the downward direction of the center part on the inner surface side, and the overlapping part is In the packaging material for rice balls in which a bag-like seaweed storage area is formed by sealing the peripheral edge of the rice ball, the seaweed storage area is formed by using a synthetic resin film with tear direction so that the tearing direction is parallel to the overlapping area. established a department,
The gist of the rice ball packaging material is that a pair of cuts are provided in parallel to the tearing direction at the edge of the synthetic resin film on the outer surface side opposite to one edge of the overlapping part.

In addition, the present invention provides a synthetic material (Δ
1. Place a sheet of seaweed on top of the fat film, and fold both sides parallel to the tearing direction inward so that their edges overlap in a non-adhesive state at the center.
The sheet-like seaweed storage area is formed by sealing the peripheral edge excluding the overlapping area, and the edge of the lower synthetic resin film facing one end of the overlapping area is attached in the tearing direction. The gist of this invention is a method for manufacturing a packaging material for rice balls in which a pair of parallel cuts are formed.

[Function] When the packaging material for rice balls according to the present invention is pinched and pulled at the pair of notches, the synthetic resin film has a tearing direction, so that the packaging material can be opened by cutting into a strip along the width of the notches. Therefore, the opening side of conventional cut tape or the like is not required.

Moreover, since this rice ball packaging material can be formed from a single synthetic resin film, it is much easier to manufacture than the conventional case where it is formed from a plurality of films.

[Example code] Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a packaging material for rice balls according to the present invention, and a sheet-like seaweed 2 for wrapping around rice balls is stored inside the packaging material. This rice ball packaging material 1
is a transparent synthetic resin film 1 with tear directionality.
In other words, as shown in Fig. 2, both sides of the synthetic resin film II parallel to the tearing direction P are bent inward, and the edge of the bent piece I2.13 is in the center. A bag-shaped storage section 17 is formed by folding them overlapping each other and sealing the peripheral edge by +5.1G except for the overlapping part I4, and the sheet-shaped /
lrr moss 2 is stored. Furthermore, the synthetic resin film 1 on the outer surface side is placed opposite to the non-adhered proper portion I4.
A pair of incisions 8 are formed in the central end of 1 in parallel to the tearing direction P.

The rice ball package B 1 thus formed is folded in half with the rice ball 3 sandwiched between the inner sides as in the conventional method, and both upper corners are folded into the rice ball 3 as shown in FIG. The rice ball 3 can be packaged by folding it to the back side, overlapping the folded ends, and pasting the seal 4.

When eating the rice ball 3, as shown in FIG. 5(a), when you pick up the pair of notches 18 with your fingers and pull them downward, this direction is the same as the tearing direction P, so the rice ball 3 is torn into strips, and then As shown in the same figure (b), it can be torn continuously beyond the bottom to the two ends on the back side. As the rice ball packaging material 1 is opened by this tearing, the rice ball packaging material 1 is divided into left and right halves, so that the divided parts can be removed with fingers as shown in FIG. 5(c).
will be exposed and placed on the outer surface of rice ball 3.

FIG. 6 shows another embodiment of the packaging material for rice balls according to the present invention, the basic structure of which is the same as that of the previous embodiment, but with respect to the tearing direction P of the synthetic resin film. The difference is that it is horizontally elongated, and members corresponding to those in the previous embodiment are shown with the same numbers, except that the numbers have a dash.

When a rice ball is packaged with this rice ball packaging material 1', a pair of notches 18' will be located at the bottom edge of the rice ball as shown in Figure 7, and in this case, as shown in Figure 8 (a). The bottom of the rice ball packaging material 1' is torn laterally and opened, and the torn rice ball packaging material 1' can be removed upward as shown in FIG. As a result, the exposed seaweed 2' can be wrapped around rice balls.

This rice ball packaging device t, li' can be manufactured in exactly the same manner as the above-mentioned rice ball packaging material 1, and the only difference is the width and length of the synthetic resin film that serves as the base material.
By just adjusting these, it is possible to run it on the same machine, and it is also possible to continuously mass-produce it using a long synthetic resin film of a predetermined width wound into a roll in the tearing direction. It is.

[Effects of the Invention] As explained in 1-1 below, according to the present invention, instead of manufacturing a packaging material for rice balls by combining a plurality of synthetic resin films, it can be easily manufactured from a single synthetic resin film. This makes it possible to significantly improve work efficiency and reduce costs. Furthermore, since the tear direction of the synthetic resin film can be used to open the package, there is no need to separately install a cut tape or other opening mechanism, which contributes to a reduction in the number of parts.
