JP5572183B2 - External sheet used for rice ball packaging sheets - Google Patents

Description

  The present invention relates to an external sheet used for a rice ball packaging sheet that can peel off an excess sheet without changing the hand or finger holding the rice ball.

  Traditionally, rice balls sold at convenience stores and supermarkets are packaged in packaging sheets for packaging rice balls. The packaging sheet is generally composed of an outer sheet and an inner sheet, and laver is accommodated between the outer sheet and the inner sheet, and generally a triangular three-dimensional rice ball is provided inside the inner sheet. The packaging sheet is attached with a peel line, holding one end of the peel line, pulling the peel line, and peeling the peel line from the external sheet, the external sheet is divided into two symmetrical shapes, respectively The inner sheet sticks to the outer sheet and the inner sheet is separated into two together with the outer sheet. When the outer sheet and the inner sheet are separated from each other by two, the seaweed is wrapped around the outside of the rice ball. Such a technique is disclosed in Patent Document 1.

  When taking out the three-dimensional rice ball from the outer sheet divided into two, while holding the rice ball and seaweed in the outer sheet on one side divided into two, Pull out from the external sheet (with rice balls and seaweed still held). By pulling out the external sheet on the other side, half of the triangular solid rice ball on the extracted side is exposed to the outside, and the exposed seaweed is wound outside the half of the rice ball that is exposed to the outside. It is turned on. After that, hold the place where seaweed is wrapped around the rice ball with your hand, and pull out the external sheet on one side you held with your hand. Half of the three-dimensional rice ball on the pulled-out side is exposed to the outside, and the seaweed exposed to the outside is wound around the outside of the half rice ball exposed to the outside. As a result, the seaweed is wound around the entire onigiri rice ball. That is, the outer sheet divided into two is pulled in a direction that separates them from each other (the inner sheet is pulled away from the triangular solid rice ball together with the outer sheet), so that the seaweed is wound around the outer side of the rice ball. As a result, the packaging sheet is removed, and the rice balls are edible with nori wrapped around the outside.

JP 2007-223607 A

  When removing the packaging sheet from the rice ball, pull out the outer sheet on the other side from the outer sheet on the other side (while holding the rice ball and seaweed), and then on the outside of the half rice ball exposed to the outside. Nori is wrapped around, but after that, in order to remove the outer sheet on one side, the nori must be held by hand outside the half of the rice balls exposed to the outside. For this reason, if your hands are dirty, you can remove the outer sheet on the other side, but remove the outer sheet on one side (while holding the rice ball and seaweed, approximately half of the outer sheet). There is a bug that cannot be done. In addition, if the outer sheet on one side is peeled off with a dirty hand, there is a problem that the rice ball must be held with the dirty hand.

  The present invention has been made in view of the above points, and even if you have a rice ball with a dirty hand or finger, you can eat a rice ball by removing the part to be peeled off and throwing away without changing the hand or finger with the rice ball It is an object of the present invention to provide an external sheet used for a rice ball packaging sheet that can be used.

  The present invention for achieving the above object is an outer sheet used for a rice ball packaging sheet having nori sandwiched between an inner sheet and a first tear line extending from one edge to the other edge, It consists of a second tear line extending from the middle of the first tear line to the middle of the first tear line, and a holding region formed at the center of the outer sheet by the first tear line and the second tear line. The holding region extends from the front side to the back side of the rice ball when the rice ball is wrapped with the packaging sheet. The present invention includes a first vertical portion in which the first tear line communicates with one edge and extends in a direction perpendicular or substantially perpendicular to the one edge, and communicates with the first vertical portion and the one edge. A first inclined portion inclined with respect to the first inclined portion, an intermediate portion communicating with the first inclined portion, a second inclined portion communicating with the intermediate portion and inclined with respect to the other edge, and the first A second vertical portion that communicates with the two inclined portions and communicates with the other edge, and extends perpendicularly or substantially perpendicularly to the other edge. is there. In the present invention, one end of the second tear line communicates with a connection position of the first vertical portion and the first inclined portion in the first tear line, and the other end of the second tear line is the first tear line. It contacts with the connection position of said 2nd perpendicular | vertical part and said 2nd inclination part in. According to the present invention, the first tear line communicates with one edge and inclines with respect to the one edge, and the first tear line communicates with the other edge and inclines with respect to the other edge.

  Next, the present invention will be described with reference to the drawings. FIG. 1 is an exploded front view of an outer sheet and an inner sheet according to the present invention and laver accommodated therebetween, and FIG. 2 is a plan view showing a state in which the outer sheet and the inner sheet of FIG. 3 is a perspective view of a state in which a triangular solid rice ball is placed on a state in which nori is sandwiched between the outer sheet and the inner sheet. A packaging sheet 10 for wrapping rice balls and nori consists of an outer sheet 12 and an inner sheet 14. A part of the outer sheet 12 and the inner sheet 14 is fixed by known means such as heat welding or pressure bonding (described later), and a laver 16 is provided between the outer sheet 12 and the inner sheet 14. As shown in FIG. 2, the inner sheet 14 includes a first inner sheet 14a and a second inner sheet 14b. When the outer sheet 12 and the inner sheet 14 are fixed, a part of them overlaps. It is said. A part of the overlapping portion 18 between the outer sheet 12 and the inner sheet 14 is indicated by a dotted diagonal line in FIG. Although it is desirable that the outer sheet 12 and the inner sheet 14 have the same shape (front shape), the present invention is not limited to this.

  The outer sheet 12 is basically a rectangular rectangle, and has a shape in which the four corners are notched. The outer sheet 12 forms a pair of short edges 20a and 20b and a pair of long edges 22a and 22b. The inner sheet 14 including the first inner sheet 14a and the second inner sheet 14b has a pair of short edge portions 24a and 24b and a pair of long edge portions 26a and 26b. The vicinity of the pair of long edge portions 22a, 22b of the outer sheet 12 and the vicinity of the pair of long edge portions 26a, 26b of the inner sheet 14 are fixed by heat welding, pressure bonding, or the like, whereby the outer sheet 12 and the inner sheet 14 ( The first inner sheet 14a and the second inner sheet 14b) are fixed. The pair of short edge portions 20a, 20b of the outer sheet 12 and the pair of short edge portions 24a, 24b of the inner sheet 14 may be temporarily fixed by pressure bonding or the like, but may not be fixed. When fixed, the temporary fixing portion can be easily released with a small force.

  As shown in FIG. 1, a series of first tear lines 28 extending from one short edge 24 a to the other short edge 24 b are attached to the outer sheet 12. The first tear line 28 is in communication with the first inclined portion 30 and the first inclined portion 30 that are directed diagonally to the left in FIG. 1 from the vicinity of the end of one short edge portion 24a toward the other short edge portion 24b. An intermediate connecting portion 32 parallel to the long edge portions 22a and 22b, and in contact with the intermediate connecting portion 32, in the vicinity of the end of the other short edge portion 24b diagonally downward to the right in FIG. Are connected in series with the second inclined portion 34. That is, the inclination directions of the first inclined portion 30 and the second inclined portion 34 are opposite directions. The first tear line 28 has been described so as to extend from the short edge portion 24a to the short edge portion 24b. However, if the outer sheet 12 is longitudinally cut (or may be crossed), its start and end points Is not limited to the short edge portions 24a and 24b, and for example, the outer edge of the portion where the notch is formed may be used as the start point or the end point of the first tear line 28. Moreover, although the intermediate connection part 32 was made into the straight line parallel to long edge part 22a, 22b, if it connects the 1st inclination part 30 and the 2nd inclination part 34, even if it is shapes, such as circular arc shape, good. Furthermore, although the first inclined portion 30 and the second inclined portion 34 are shown in a straight line shape, they may be in a curved shape having a large polarity radius.

A second tear line 36 is attached to the outer sheet 12. The second tear line 36 extends from a position that communicates with the middle of the first inclined portion 30 to a position that communicates with the middle of the second inclined portion 34, and the first inclined portion 38 that faces diagonally downward to the right in FIG. And an intermediate connecting portion 40 that communicates with the first inclined portion 38 and is parallel to the long edge portions 22a and 22b, and communicates with the intermediate connecting portion 40, and is directed diagonally downward to the left in FIG. The second inclined portion 42 communicating with the middle of the second inclined portion 34 is connected in series. That is, the inclination directions of the first inclined portion 38 and the second inclined portion 42 are opposite directions. Further, although the intermediate connecting portion 40 is a straight line parallel to the long edge portions 22a and 22b, the intermediate connecting portion 40 may have a shape such as an arc shape as long as it connects the first inclined portion 38 and the second inclined portion 42. good. Furthermore, although the first inclined portion 38 and the second inclined portion 42 are shown in a straight line shape, they may be in a curved shape having a large polarity radius.

  A substantially hexagonal holding region 44 surrounded by the first tear line 28 and the second tear line 36 is formed at the center of the outer sheet 12. The holding area 44 is for holding a rice ball by holding a predetermined portion with two fingers. A description of the state where the rice balls are held in the holding area 44 will be described later.

  As shown in FIG. 3, the outer sheet 12 and the inner sheet 14 are fixed, and at the center of the packaging sheet 10 provided with the laver 16 (see FIG. 1) between the outer sheet 12 and the inner sheet 14, FIG. 4 shows a front view of the state in which the rice ball 46 is placed on the sheet 14 and then the packaging sheet 10 is folded in two around the rice ball 46. The rice ball 46 is preferably a three-dimensional shape having a triangular front shape. Thereafter, the packaging sheet 10 is bent in accordance with the shape of the rice ball 46 and wrapped with the packaging sheet 10 to form a rice ball product 48 (FIG. 5). In the rice ball sales product 48, the holding area 44 is set so as to extend from the front to the back of the rice ball sales product 48, so that the front holding area 44 and the holding area 44 on the back side are provided with an area for placing a finger. To. A holding region 44 extending from the front side to the back side of the rice ball 46 is formed to a position extending beyond the center of gravity of the rice ball 46. The dot-and-dash line locations in the center on both sides of the holding region 44 indicate the pinching locations 50 held by the fingers. That is, the rice ball 48 is sandwiched between the front side and the back side by sandwiching the pinch portion 50 of the holding area 44 on the front side and the pinching portion 50 of the holding area 44 on the back side with fingers. The positions of these sandwiching points 50 may be the positions of the center of gravity of the rice balls 46.

In order to take out the rice balls from the rice ball product 48 shown in FIG. 5, first, the fingers hold the center pinching points 50 (shown by dotted lines) on both sides of the holding region 44. That is, for example, with the two fingers such as the thumb and the index finger, the sales product 48 has a holding area 44 on the front side and a holding area 44 on the back side. Thereafter, the first tear line 28 of the packaging sheet 10 is torn, and the first peeled portion 52 having the shape shown in FIG. The first inner sheet 14a is attached to the first peeling portion 52, and the first inner sheet 14a is also peeled off. In the state where the first peeling portion 52 is removed, the seaweed 16 is wound around the rice ball 46 of the exposed portion.

Thereafter, the second tear line 36 is torn off, and the second peeled portion 54 having the shape shown in FIG. The second inner sheet 14b is attached to the second peeling portion 54, and the second inner sheet 14b is also peeled off. In the state where the second peeled portion 54 is removed, the seaweed 16 is wound around the rice ball 46 of the exposed portion.

FIG. 7 shows a state where the first peeled portion 52 and the second peeled portion 54 of FIG. In the state of FIG. 7, the seaweed 16 is wound around the outside of the rice ball 46, and the holding area 44 extending from the front side to the back side is attached to the rice ball 46 with the seaweed 16 attached to the outside. During this time, the finger having the front-side pinching portion 50 and the back-side pinching portion 50 remains as it is, and there is no need to change the finger.

As described above, in the present invention, when the rice ball 46 is eaten, the rice balls sold in a state where the pinching portion 50 of the holding region 44 on the front side and the pinching portion 50 of the holding region 44 on the back side are pinched by two fingers. The first tear line 28 is torn from 48 to peel off the first peeled portion 52 (FIG. 6), and the second tear line 36 is torn off and the second peeled portion 54 (FIG. 6) is peeled from the rice ball product 48. As described above, in the present invention, even if the hands and fingers are dirty, the portions other than the holding region 44 in the packaging sheet 10 are peeled in a state where the holding region 44 on the front side and the holding region 44 on the back side are sandwiched between fingers. Thus, the rice ball 46 can be exposed. For this reason, even if the hand or finger is dirty, the rice ball 46 can be exposed without making the rice ball 46 dirty. Further, the position of the pinched portion 50 of the holding area 44 sandwiched between two fingers is the center of gravity position of the rice ball 46. In general, a tool is provided at the center of gravity of the rice ball 46. Therefore, the rice ball 46 can be eaten by squeezing the pinching portion 50 without spilling the ingredients.

  The holding region 44 shown in FIG. 7 has an upper end position P on both the front side and the back side, extending on or above the center of the triangle area of the front and back sides of the rice ball shown in FIG. . For this reason, when the triangular rice ball holding area 44 in FIG. 7 is held from the top with the finger held, the mouth immediately hits the upper end position P of the holding area 44, and the rice ball is difficult to eat. . For this reason, the upper end position P of the holding region 44 is desired to be lower in FIG. However, the first tear line 28 of the outer sheet 12 extends from one short edge portion 20a to the other short edge portion 20b, communicates with one short edge portion 20a with the first inclined portion 30, and the other It is necessary to communicate with the short edge 20b and the second inclined portion 34. That is, both the location where the first tear line 28 communicates with one short edge portion 20a and the location where the other short edge portion 20b communicates are inclined with respect to the short edge portions 20a, 20b. There is a drawback that the position of the upper end position P of the holding region 44 in FIG. 7 cannot be lowered.

  In order to eliminate the drawbacks, the height of the upper end position P of the holding region 44 can be reduced by changing the shape and position of the first tear line 28 and the second tear line 36 in the outer sheet 12. A modification example is shown in FIG. In FIG. 8, the external sheet 60 is used instead of the external sheet 12. 8 and 10, the same reference numerals as those in FIG. 1 indicate the same members. A holding region 66 is formed in the outer sheet 60 by the first tear line 62 and the second tear line 64. One end of the first tear line 62 communicates with one short edge portion 20a, and the other end communicates with the other short edge portion 20b. The first tear line 62 is connected to one short edge portion 20a and extends in a direction perpendicular to or substantially perpendicular to the short edge portion 20a, followed by a first inclined portion 70 (short edge portion). Part 20a and the first vertical part 68), the following intermediate part 72 (arranged substantially perpendicular to the short edge part 20a and the short edge part 20b), and the subsequent second inclination A portion 74 (inclined with respect to the short edge portion 20b and a second vertical portion 76 to be described later), and is connected to the other short edge portion 20b and is perpendicular to the short edge portion 20b. And a second vertical portion 76 extending in a direction or substantially vertical direction.

The second tear line 64 is centered on a line connecting the first vertical portion 68 and the second vertical portion 76 in FIG. 8, and the first inclined portion 70, the intermediate portion 72, and the second inclined portion 74 in the first tear line 62. It is formed in a symmetrical position and shape. The second tear line 64 includes a third inclined portion 78, an intermediate portion 80 that communicates with the third inclined portion 78, and a fourth inclined portion 82 that communicates with the intermediate portion 80. It is desirable that one end (free end) of the third inclined portion 78 communicates with a connection position between the first vertical portion 68 and the first inclined portion 70 in the first tear line 62 (the holding region 66 may be symmetrical). However, one end of the third inclined portion 78 may communicate with the middle of the first inclined portion 70. It is desirable that one end (free end) of the fourth inclined portion 82 communicates with a connection position between the second vertical portion 76 and the second inclined portion 74 in the first tear line 62 (the holding region 66 should be symmetrical). However, one end of the fourth inclined portion 82 may communicate with the middle of the second inclined portion 74.

The longer the length of the first vertical portion 68 is, the shorter the connection position between the first inclined portion 70 and the third inclined portion 78 (the portion that becomes the upper end position Q of the holding region 66) is the short edge in the outer sheet 60. The position is away from the portion 20a. The longer the length of the second vertical portion 76 is, the shorter the connection position between the second inclined portion 74 and the fourth inclined portion 82 (the position that becomes the upper end position Q of the holding region 66) is the short edge in the outer sheet 60. The position is away from the portion 20b. It is desirable that the holding region 66 extending from the front side to the back side of the rice ball 46 is formed in a shape that does not reach the position of the center of gravity of the rice ball 46. As a result, the upper end position Q of the holding area 66 is reduced in height, making it easier to eat rice balls. It is desirable that the upper end position Q of the holding area 66 does not reach the center of gravity position of the rice ball 46 regardless of whether the shape of the rice ball 46 is round or triangular when viewed from the front.

Here, when the rice ball 46 is exposed by removing the packaging sheet, the first tear line 62 is first removed from the state shown in FIG. 9, and then the second tear line 64 is removed to obtain the state shown in FIG. . As shown in FIG. 10, the upper end Q of the holding portion 66 can be made lower than the upper end position P of the holding region 44 in FIG. 7, and even if it covers from the upper side of the rice ball 46 in FIG. The problem of touching the upper end Q of the can be solved.
