Description

  The present invention relates to a packaged rice cake in which a rice cake is packaged by a packaging sheet formed by sandwiching a sheet-like food product between an inner film and an outer film, and more specifically, it suppresses tearing of the sheet-shaped food product. It relates to a packaged rice cake.

  So-called packaged rice chunks in which rice chunks such as triangular rice balls are wrapped with a packaging sheet are sold at convenience stores and the like. As the packaging sheet, a triple-structured packaging sheet formed by sandwiching a sheet-like food (seaweed) between an outer film and an inner film is widely known.

  For example, in Patent Document 1, an outer film and an inner film can be divided at the bottom of a triangular rice cake, and a packaging sheet sandwiching sheet-like food is tightly wound around the rice cake to create a packaged rice cake. . And in order to unwrap the packaged rice cake, first, the outer film is divided, and the rice cake wrapped in the sheet-like food is obtained by extruding the rice cake together with the sheet-like food from the divided portion. .

Japanese Patent No. 5816447

  In patent document 1, when a rice lump was extruded, the sheet-like food might be torn. When the sheet-like food is torn, the number of sheet-like food wound around the lump is reduced, and the sheet-like food remaining on the packaging sheet is wasted. In addition, a lump of rice wrapped in a torn sheet-like food does not look good.

  The objective of this invention is providing the packaged rice lump which can prevent the tear of a sheet-like foodstuff.

The packaged rice lump of the present invention is
In the unfolded state, a sheet-like food (4) is sandwiched between a rectangular outer film (2) and an inner film (3) arranged on the back side of the outer film (2). (2) has a severable portion (21) extending in the width direction substantially at the center in the longitudinal direction, and the inner film (3) includes two film pieces (31) and (31) as the outer film (2). ) Is wrapped in a substantially central portion in the longitudinal direction, and the rice cake (6) is packaged by the packaging sheet (1) formed by welding with the outer film (2) at the periphery of the sheet-like food (4). Wrapped rice cake,
The rice mass (6) is formed in a flat shape having a height H and a thickness T,
The sheet-like food (4) has a length L in the longitudinal direction of 2H + T or less.

  The sheet-like food (4) can have a rectangular corner chamfered shape.

  A sheet-like food (4) can be made into the shape by which the edge part of the longitudinal direction was rounded and chamfered.

  The severable part (21) is formed by adhering the cut tape (22) to the inner side of the outer film (2) over the entire length in the width direction. The outer film (2) has a severable part (21) Cuts (23) and (23) for easily dividing the separable portion (21) are formed near one or both of the end portions.

  The packaged rice lump of the present invention has the length L of the sheet-like food (4), the height H and the thickness T of the rice lump (6) as described above. When extruding (6) together with the sheet-like food (4), the sheet-like food (4) can be prevented from being broken. Therefore, the sheet-like food (4) wound around the lump (6) is not reduced, and the sheet-like food (4) remains on the packaging sheet (1) and is not wasted. Furthermore, since the sheet-like food (4) is not torn, the appearance of the rice cake (6) wrapped in the sheet-like food (4) is also good.

  The present invention will be described below with reference to the drawings.

  As shown in FIG. 1 to FIG. 3, the packaging sheet (1) is composed of a rectangular and transparent outer film (2), and a film piece (about half the length of the long side in the longitudinal direction of the outer film (2)). 31) A substantially rectangular sheet food (4) is sandwiched between the inner film (3) made of (31) and (31).

  In this embodiment, the outer film (2) is a vertically long film having a length in the longitudinal direction of about 240 mm and a length in the width direction of about 140 mm. The outer film (2) has a severable portion (21) that can sever the entire length of the outer film (2) in the width direction at the center in the longitudinal direction.

  The severable portion (21) of the example is obtained by bonding the cut tape (22) over the entire length in the width direction of the outer film (2). When one end of the cut tape (22) is pulled, the outer film (2) can be torn along the tape direction.

  At one or both ends of the outer film (2), cut outside the cut tape (22), close to the cut tape (22) and in parallel with the cut tape (22) (23) (23) It is desirable. Thereby, the outer film (2) can be divided by pinching the notches (23) and (23) and pulling the cut tape (22).

  The inner film (3) is composed of two identical film pieces (31) (31), and the inner edges of the inner film (3) overlap each other on the severable part (21) of the outer film (2) by about 10 mm. It is piled up with. That is, in this embodiment, each film piece (31) (31) is about 125 mm in the longitudinal direction of the outer film (2), and the width direction is about 140 mm which is the same as the outer film (2).

  As the inner film (3), it is desirable to use a film made of a material to which rice grains do not easily adhere. For example, as the inner film (3) (film pieces (31) and (31)), an embossed film in which concave portions and convex portions are uniformly distributed can be used. By using the embossed film, it is possible to improve the detachability from the rod-shaped rice cake (6), and it is possible to prevent the rice grains from adhering to the inner film (3) and the like.

  The sheet-like food (4) is a sheet-like seaweed in the examples. The sheet-like food (4) is not particularly limited as long as it is a thin food such as those obtained by forming a rag kombu into a sheet, or a thinly stretched koji.

  As shown in FIG. 4, the sheet-like food (4) has a length L in the longitudinal direction of 2H + T or less when the height of the rice block (6) described later is H and the thickness is T, that is, L ≦ 2H + T. Desirably, the length L of the sheet-like food (4) is set to L ≦ 2H + T−5 mm to 10 mm with a margin. The reason will be described later. In the embodiment, the length L of the sheet-like food (4) is 165 mm shorter by 7 mm than 2H + T (= 172 mm). The width of the sheet-like food (4) is the same as or slightly longer than the rice block (6), and is about 90 mm in the example of FIG.

  The sheet-like food (4) can be of a substantially rectangular shape, but as shown in the figure, a rectangular shape with a chamfered corner or a shape with a rounded chamfered end in the longitudinal direction is used. Things can also be used.

  As shown in FIGS. 1 to 3, the wrapping sheet (1) has a sheet-like food (4) placed substantially at the center of the outer film (2), from which a film piece ( 31) The outer film (2) and the inner film are placed along the periphery of the outer film (2) so that the (31) is slightly overlapped on the separable portion (21) and surrounds the sheet-like food (4). (3) can be formed by linearly welding (11) and (11). Note that no welding is performed on the overlapping portions of the film pieces (31) and (31).

  In addition, it is desirable to prevent welding of the sheet-like food (4) by applying welding (12) to one end or the vicinity of both ends in the longitudinal direction of the sheet-like food (4).

  The rice cake (6) is made into a rice cake (6) on the packaging sheet (1) having the above structure. As shown in FIG. 2, the rice block (6) is a block formed by flattening white rice or cooked rice. Preferably, both side surfaces are substantially parallel, and the both side surfaces are connected to each other by a flat or curved peripheral surface. As shown in FIG. 4, the rice lump (6) has a height of H and a thickness of T, and the length L of the sheet-like food (4) is determined based on these dimensions. Note that the rice lump (6) may be partially or entirely sprinkled with sprinkled food such as sesame, placed with ingredients, or sandwiched with ingredients.

  The illustrated rice cake (6) is a triangular rice ball having a height L of about 70 mm and a thickness T of about 32 mm (that is, 2H + T = 172 mm). In addition, the lump (6) may be a rectangle, a circle, or an ellipse instead of a triangle. In order to make the rice lump (6) slide well from the inner film (3) and drop it, the sides and corners of the rice lump (6) are preferably chamfered. The chamfering can be exemplified by round chamfering. R is preferably 5 mm or more, and more preferably approximately 8 mm.

  As shown in FIG. 2, the rice cake (6) having the above configuration is placed on a packaging sheet (1) with the inner film (3) side facing upward. In the case of a triangular rice ball, the rice lump (6) is placed so that one of its peripheral surfaces (referred to as the bottom surface) faces the separable portion (21) when the packaging sheet (1) is folded. More specifically, the bottom surface of the rice lump (6) is opposed to the longitudinal center of the sheet-like food (4).

  The packaging sheet (1) may be folded in advance in a U shape with the separable part (21) in between, and the rice cake (6) may be sandwiched between them.

  As shown in FIG. 2, after placing the rice cake (6) on the packaging sheet (1), as shown by the arrow C in the figure, one end of the packaging sheet (1) is wrapped around the rice cake (6) so as to wrap the rice cake (6). 6).

  Next, as shown in FIG. 5, the end of the packaging sheet (1) is placed along the peripheral surface of the rice chunk (6) as indicated by the arrow D (in FIGS. 5 to 7, the inner film (3 ) And sheet-like food (4) are not shown). Subsequently, as shown by an arrow E in FIG. 6, one corner of the other end of the packaging sheet (1) is covered so as to wrap the rice lump (6), and further, as shown by an arrow F in FIG. Put the horn over the rice block (6).

  Finally, as shown in FIG. 7, the end of the intersecting packaging sheet (1) is sealed by the fastening means (5), whereby a packaged rice lump can be obtained. Although the illustrated fastening means (5) is a tape, it can be sealed by using a label on which the date of manufacture and contents are described, or by welding.

  8 is a cross-sectional view taken along line BB in FIG. In the figure, a space is provided between the rice chunk (6) and the packaging sheet (1), but there is actually no gap between the rice chunk (6) and the packaging sheet (1). As shown in FIG. 8, the rice cake (6) is covered with film pieces (31) and (31), sheet food (4), and outer film (2) constituting the inner film (3) from the inside. The bottom surface of the lump (6) is opposed to the overlapping portion of the film pieces (31) and (31) and the cut tape (22) which is the separable portion (21). As shown in the enlarged circled portion of FIG. 8, it can be seen that the upper end of the sheet-like food (4) substantially coincides with the chamfered portion of the upper end of the rice lump (6).

  The packaged rice lump having the above configuration can be unpacked in the following manner.

  First, as shown in FIG. 9, the separable portion (21) is cut by cutting the cut tape (22) which is the separable portion (21) (between the cut tapes (23) and (23) if formed). Pull the outer film (2) in the width direction along the severable part (21). Thereby, a cut end (25) is opened and formed in the outer film (2).

  Next, by turning the cut end (25) of the packaged rice cake downward, as shown in FIG. 10, the rice cake (6) removes the sheet-like food (4) from the outer film (6) by its own weight. Drop while pulling from between 2) and the inner film (3). As the rice lump (6) falls, the inner film (3) opens when the film pieces (31) and (31) are unoverlapped.

  At this time, since the length L of the sheet-like food (4) is L = 2H + T with respect to the height H and thickness T of the rice lump (6), the upper end of the sheet-like food (4) is the lump (6 ) Is coincident with the upper end of the rice cake and does not protrude above the rice block (6). That is, the sheet-like food (4) is not sandwiched between the outer film (2) and the inner film (3) above the lump (6). Therefore, when the rice lump (6) is dropped, the sheet-like food (4) is pulled out between the films (2) and (3) without being broken. Moreover, as above-mentioned, the corner | angular part of a sheet-like food (4) is torn between films (2) and (3) by chamfering the corner | angular part of a sheet-like food (4), or rounding the edge part. Can be prevented as much as possible.

  In addition, by chamfering the sides and corners of the rice lump (6), the contact resistance with the inner film (3) can be reduced, and the rice lump (6) can be smoothly formed without losing its shape. Can be dropped.

  FIG. 11 shows a state in which the rice cake (6) is completely detached from the packaging sheet (1). As shown in the figure, the rice cake (6) is made up of an unbroken sheet-like food (4). It is taken out from the packaging sheet (1) in a state where it is covered.

  The rice cake (6) is covered with the sheet-shaped food (4) without being broken, so that it looks good and there is no waste of the sheet-shaped food (4).

  The rice lump (6) unwrapped and covered with the sheet-like food (4) can be eaten by winding the end of the sheet-like food (4) around the rice lump (6).

  The packaged rice lump of the present invention can be obtained by dividing the outer film (2) at the severable portion (21) and turning the cut end (25) downward, so that the rice lump (6) covered with the sheet-like food (4) is removed. Since it can be obtained, it is possible to unwrap the packaged rice lump in a manner as simple as possible compared to the conventional packaged rice lump.

  In addition, when the rice lump (6) does not fall well from the packaging sheet (1), the rice lump (6) can be easily dropped by gently shaking downward.

  The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. In addition, the configuration of each part of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
