Description

The present invention relates to a food packaging material, a food packaging material raw material, and a food packaging material.

In recent years, food packaging materials have been required to be able to be easily opened without directly touching the food and to be able to eat the food hygienically. As such a food packaging material, a material for taking out food by pulling a cut tape and dividing the food packaging material into two is known.

Specifically, Patent Document 1 describes, as such a food packaging material, a food packaging material having an outer sheet and a fixing sheet (hand stain prevention sheet) detachably fixed to the inside of the outer sheet. Has been proposed. In this food packaging material, when the outer sheet divided into two at the time of opening is removed from the food, the fixing sheet is peeled off from the outer sheet, so that the fixing sheet is held on the food side. As a result, the food can be held through the fixing sheet, so that the food can be eaten hygienically.

Japanese Unexamined Patent Publication No. 2014-73115

However, in the above-mentioned food packaging material, when the outer sheet is divided into two and then removed from the food, a force for peeling the fixing sheet from the outer sheet is required. Therefore, when the outer sheet is removed from the food, an extra force is applied to the food, and the food may collapse or scatter.

Therefore, it is an object of the present invention to provide a food packaging material that can be easily removed from food and that the fixed sheet can be smoothly separated from the outer sheet. Another object of the present invention is to provide a raw material for a food packaging material used for manufacturing the food packaging material, and a food packaging body in which the food is packaged with the food packaging material.

The food packaging material according to the present invention has an outer sheet in which the third part formed between the first part and the second part can be separated from the first part and the second part, and the outer sheet. A fixing sheet that overlaps with the sheet and is detachably fixed to the outer sheet is provided, and the fixing sheet includes a fixing portion that is detachably fixed to a third portion of the outer sheet.

According to such a configuration, in a state where the food is packaged by the food packaging material, the third part is separated from the first part and the second part, so that the first part and the second part can be obtained. Since the food can be taken out from the space, the food packaging material can be easily removed from the food.
In addition, when the third part is separated from the first part and the second part in the state where the food is packaged with the food packaging material, the fixed part of the fixing sheet is peeled off from the third part. When removing the packaging material from food, it is not necessary to peel off the fixed portion of the fixed sheet from the outer sheet. Therefore, the fixing sheet can be smoothly separated from the outer sheet. Further, when the food packaging material is removed from the food, the fixing sheet and the food are integrated, so that the food can be eaten hygienically without directly touching the food.

The third portion is a band-shaped region extending in one direction in the outer sheet, and it is preferable that the fixing sheet includes at least one fixing portion and the region other than the fixing portion is not fixed to the outer sheet.

According to such a configuration, the fixing sheet is provided with at least one fixing portion, and the region other than the fixing portion is not fixed to the outer sheet, so that the entire fixing sheet is fixed to the outer sheet (in other words). Then, the peeling of the fixed portion from the third portion can be performed with less resistance than in the case where the entire fixed sheet is the fixed portion).

The outer sheet is provided with at least one opening strip extending in one direction and at least partially overlapping the third portion, and the opening strip is at least partially fixed. The fixing portion of the fixing sheet that overlaps with the sheet may be fixed to the outer sheet at a position that overlaps with the opening strip.

According to such a configuration, the fixing portion of the fixing sheet is fixed to the outer sheet at a position overlapping with the opening strip, so that the outer sheet is cut along the opening strip to separate the third portion. At that time, the fixed portion can be reliably peeled off from the third portion.

The food packaging material according to the present invention includes at least two opening strips, and the fixing portion of the fixing sheet may be fixed to the outer sheet between two adjacent opening strips.

According to such a configuration, the fixing portion of the fixing sheet is fixed to the outer sheet between two adjacent opening strips, so that the outer sheet is cut along the opening strip to form a third portion. At the time of separation, the fixed portion can be reliably peeled off from the third portion.

The food packaging material raw material according to the present invention is formed by continuously forming a plurality of any of the above food packaging materials.

The food package according to the present invention includes any of the above food packaging materials and the food packaged in the food packaging material, and the food overlaps at least a part of the fixing sheet.

As described above, according to the present invention, it is possible to provide a food packaging material that can be easily removed from food and that the fixed sheet can be smoothly separated from the outer sheet. Further, it is possible to provide a food packaging material raw material used for producing the food packaging material and a food packaging body in which the food is packaged with the food packaging material.

The shape of the cooked rice processed food A1 is not particularly limited, and examples thereof include a triangular shape, a square shape, a spherical shape, a bale shape, a circular shape, and an elliptical shape. In this embodiment, as the cooked rice processed food A1, a triangular shape will be described as an example. The sheet-shaped food A2 is not particularly limited, and examples thereof include kelp and tatami iwashi. The shape of the sheet-shaped food A2 is not particularly limited, and examples thereof include a triangular shape, a quadrangular shape, and a circular shape.

The food packaging material 1 includes an outer sheet 2 in which the third portion 2C formed between the first portion 2A and the second portion 2B can be separated from the first portion 2A and the second portion 2B. A fixing sheet 3 that overlaps with the outer sheet 2 and is detachably fixed to the outer sheet 2 is provided. Further, the outer sheet 2 includes an outer sheet main body 2d having a size capable of wrapping food A, and at least one (specifically, two) opening strips 4 attached to the outer sheet main body 2d. And prepare. Further, the food packaging material 1 includes an inner sheet 6 that overlaps with the outer sheet 2. Then, the fixing sheet 3 is located between the outer sheet 2 and the inner sheet 6, and the sheet-shaped food A2 is located between the fixing sheet 3 and the inner sheet 6.

The materials of the outer sheet 2, the fixing sheet 3, and the inner sheet 6 are not particularly limited, and are, for example, synthetic resin films such as polyethylene and polypropylene, composite film films such as these synthetic resins and fibers, and paper. , And a composite sheet of paper and synthetic resin. Examples of the synthetic resin film include a uniaxially stretched synthetic resin film, a biaxially stretched synthetic resin film, and a non-stretched synthetic resin film. Further, the materials of the outer sheet 2, the fixing sheet 3, and the inner sheet 6 may be the same or different from each other. Further, at least one of the outer sheet 2, the fixing sheet 3, and the inner sheet 6 may be transparent, opaque, or translucent. Further, since the fixing sheet 3 is in direct contact with food A (sheet-shaped food A2 in this embodiment), food A (sheet-shaped food A2 in this embodiment) has a property of being difficult to adhere to. It is preferable to use.

The outer sheet 2 has a size capable of wrapping the food A. In the present embodiment, the outer sheet 2 is formed in a rectangular shape, specifically, a rectangular shape, one direction (hereinafter, also referred to as the first direction) is the longitudinal direction, and the other direction intersecting the first direction (hereinafter, also referred to as the first direction). , Also referred to as the second direction) is the width direction. Further, the outer sheet 2 is provided with two notches 2a and 2a at one end in the first direction. The two cut portions 2a and 2a are formed in a linear shape extending in the first direction, and one end of each is in contact with the edge of the outer sheet 2. As a result, the region between the two cut portions 2a and 2a in the outer sheet 2 is separated from the other regions to form the knob portion 2b.

The outer sheet 2 configured as described above can be divided in the second direction. Specifically, by pulling the grip portion 2b from one end side to the other end side of the outer sheet 2 in the first direction, the outer sheet 2 is first placed from the other end of each of the two cut portions 2a and 2a. It is possible to cut in the direction. Then, when the outer sheet 2 is cut, the band-shaped region between the two planned cutting lines CL starting from the other ends of the two cut portions 2a and 2a is separated from the other regions. As a result, the outer sheet 2 is divided in the second direction. That is, in the present embodiment, the outer sheet 2 has the first portion 2A on one side in the second direction, the second portion 2B on the other side in the second direction, and the first in the second direction. A third site (specifically, a band-shaped region extending in the first direction) 2C is provided between the site 2A and the second site 2B. Then, by cutting the outer sheet 2 to separate and remove the third part 2C from the first part 2A and the second part 2B, the outer sheet 2 becomes the first part 2A and the second part 2B. It can be divided.

The two opening strips 4, 4 (for example, cut tape, thread, etc.) are attached to one surface of the outer sheet 2 so that the first direction is the length direction. Further, the two opening strips 4 and 4 are attached over the entire length of the outer sheet 2 in the first direction. Further, one end of the two opening strips 4 and 4 in the first direction is located between the two notches 2a and 2a (that is, overlaps with the knob 2b). Further, the two opening strips 4 and 4 overlap at least a part with the third portion 2C of the outer sheet 2 (specifically, they overlap over the entire length of the band-shaped third portion 2C). Further, the two opening strips 4 and 4 are located substantially at the center of the outer sheet 2 in the second direction. Further, the two opening strips 4 and 4 overlap with the overlapping portion 6b formed by overlapping the ends of the inner sheet pieces 6a and 6a described later.

Further, each of the two opening strips 4 and 4 is arranged in a corrugated shape curved in the second direction. Specifically, each of the two opening strips 4 and 4 meanders in the first direction (in the present embodiment, the center line extending in the first direction of the outer sheet 2), and the outer sheet is formed. It is arranged over the entire length of 2. Then, the two opening strips 4 and 4 are arranged line-symmetrically with respect to the first direction (in the present embodiment, the center line extending in the first direction of the outer sheet 2), so that the two opening strips are arranged. Two intersection positions 4a where the bodies 4 and 4 intersect are formed.

Then, the distance between the two opening strips 4 and 4 is between the intersection positions 4a and 4a in the first direction, as the distance from the two notches 2a and 2a (that is, the knob portion 2b) increases in the first direction. It is wider than the distance between the two notches 2a and 2a. The distance between the two opening strips 4 and 4 is widest at the substantially central portion between the intersection positions 4a and 4a in the first direction. Further, the distance between the two opening strips 4 and 4 between both ends of the outer sheet 2 and the two crossing positions 4a and 4a in the first direction is the distance between the two opening strips 4 between the crossing positions 4a and 4a. , 4 narrower than the widest interval.

By attaching the two opening strips 4 and 4 as described above to the outer sheet 2, the third portion 2C of the outer sheet 2 is formed from one end portion (pinching portion 2b) to the central portion in the first direction. It becomes wider toward (specifically, along the two opening strips 4 and 4).

The fixing sheet 3 is fixed to one surface of the outer sheet 2 and is located between the outer sheet 2 and the sheet-shaped food A2 when the food A is packaged with the food packaging material 1. The size of the fixing sheet 3 is not particularly limited, and in the present embodiment, it is smaller than the outer sheet 2. The outer shape of the fixing sheet 3 is not particularly limited, and for example, a rectangular shape, a polygonal shape other than the rectangular shape, an elliptical shape, or the like can be adopted. It has a rectangular shape (specifically, a rectangular shape). Since the fixing sheet 3 has a square shape, the corners of the fixing sheet 3 attached to the food A can be easily picked, so that a part of the fixing sheet 3 becomes an obstacle when eating the food A. , The corner portion of the fixing sheet 3 can be pinched and the food A can be eaten while avoiding the portion.

Further, the fixing sheet 3 includes a fixing portion 3a that is detachably fixed to a third portion 2C (a portion removed by cutting the outer sheet 2) of the outer sheet 2. The fixing portion 3a is detachably fixed to the outer sheet 2 at the region between the two opening strips 4 and 4 (specifically, the region between the two intersecting positions 4a and 4a). Thereby, when the outer sheet 2 is cut along the two opening strips 4 and 4 to separate the third portion 2C, the fixing portion 3a can be reliably peeled from the third portion 2C. .. Further, the fixing portion 3a is formed on a part of the fixing sheet 3. That is, in the fixing sheet 3, the parts other than the fixing portion 3a do not stick to the outer sheet 2 (they are not fixed). Further, the fixing sheet 3 includes a plurality of fixing portions 3a. Specifically, the fixing sheet 3 is provided with fixing portions 3a at at least two positions (specifically, control positions with respect to the central portion of the fixing sheet 3 in the first direction) spaced apart from each other in the first direction.

That is, the fixing sheet 3 is provided with the fixing portions 3a at at least two places at least two places apart from each other in the extending direction (first direction) of the band-shaped third portion 2C, and the region other than the fixing portion 3a is on the outer sheet 2. By being non-fixed, the fixing sheet 3 can be stably fixed to the outer sheet 2 and the fixing sheet 3 is prevented from wrinkling or being distorted as compared with the case where there is only one fixing portion 3a. The aesthetic appearance of the food packaging material 10 can be enhanced). Further, since the fixing sheet 3 is provided with the fixing portions 3a at at least two places at intervals in the first direction, the fixing portions 3a are formed when the raw material of the food packaging material described later is wound in the first direction. Wrinkles are less likely to occur on the fixing sheet 3 than when there is only one. Further, the third portion 2C is a band-shaped region extending in one direction, and the fixing sheet 3 is provided with the fixing portions 3a at at least two places spaced apart from each other in the first direction, whereby the band-shaped third portion 2C is formed. When the first part 2A and the second part 2B are separated by pulling in the first direction, the fixing part 3a is peeled from the third part 2C one by one in order, so that the fixing part 3a is fixed from the outer sheet 2. The sheet 3 can be easily separated.

The fixing portion 3a may be heat-welded or ultrasonically welded to the outer sheet 2 (specifically, the third portion 2C), or may be fixed by an adhesive. Further, the shape of the fixing portion 3a is not particularly limited. Specifically, the fixing portion 3a is formed in a convex shape toward one end side of the outer sheet 2 in the first direction. In the present embodiment, the fixing portion 3a is formed so that the outer peripheral shape of the outer sheet 2 on the one end side of the central portion in the first direction is convex (more specifically, an arc shape) toward the one end side. More specifically, the fixing portion 3a is formed in a circular shape.

The inner sheet 6 can be divided in the second direction. Specifically, the inner sheet 6 includes two inner sheet pieces 6a and 6a. The two inner sheet pieces 6a and 6a are arranged in parallel in the second direction, and include an overlapping portion 6b in which the end portions overlap each other. The overlapping portion 6b is located at a substantially central portion of the inner sheet 6 in the second direction and is formed so as to extend in the first direction. Then, the two inner sheet pieces 6a and 6a are separated from each other in the second direction, so that the inner sheet 6 can be divided in the second direction.

In the food packaging material 1 configured as described above, the outer sheet 2 (specifically, the outer sheet main body 2d) and the inner sheet 6 are joined so as to surround the sheet-shaped food A2. Specifically, in the food packaging material 1, as shown in FIG. 2, the outer sheet 2 (specifically, the outer sheet main body 2d) and the inner sheet 6 are joined at both ends 1a and 1b in the first direction.

Fold it in half and fold the folded side along the side surface (triangular slope) of the triangular cooked rice processed food A1. As a result, the region on the one end 1a side of the food packaging material 1 covers the front surface of the triangular cooked rice A1, and the region on the other end 1b side covers the back surface of the triangular cooked rice A1. cover. At this time, the fixing sheet 3 is formed with regions facing each other across the food A, and the fixing portion 3a is located in each of the facing regions. Then, the region of the food packaging material 1 that does not overlap with the cooked rice processed food A1 is folded back along the triangular shaped cooked rice processed food A1 and overlapped on the back surface of the cooked rice processed food A1 as shown in FIG. .. Then, by attaching a label (not shown) to the overlapping portion on the back surface of the triangular rice-processed food A1 in the food packaging material 1, the food A is formed in the food packaging material 1 shown in FIG. 4A. The packaged food package 100 is formed.

When the food A is taken out from the food package 100, the picking portion 2b is picked and pulled along the two opening strips 4 and 4, and the outer sheet 2 is cut as shown in FIG. do. As a result, the third part 2C is separated from the first part 2A and the second part 2B in the outer sheet 2, and the outer sheet 2 is divided into the first part 2A and the second part 2B. At this time, since the cutting of the outer sheet 2 proceeds along the two opening strips 4 and 4, the third portion 2C is wider toward the center side in the first direction than the vicinity of the knob portion 2b. It becomes.

Further, with the cutting of the outer sheet 2 (separation of the third part 2C from the first part 2A and the second part 2B), the fixing part 3a of the fixing sheet 3 becomes the third part 2C of the outer sheet 2. Peel off from. Then, by pulling the first portion 2A and the second portion 2B in the second direction, as shown in FIG. 3C, the cooked rice processed food A1 and the sheet-shaped food A2 are integrated into the food A.
