Description

  The present invention relates to a packaged triangular rice ball (hereinafter referred to as “wrapping rice ball”) in which a substantially rectangular packaging sheet is wrapped along the shape of a triangular rice ball rice.

FIG. 12 is a front view of this conventional packaging rice ball, and FIG. 13 is a side view.
The conventional packaging rice ball (5a) is an equilateral triangle when viewed from the front, and is formed in the same thickness from the bottom to the top.
A perforation (17) and a portion (12) capable of being cut by a cut tape are formed at the center in the width direction of the packaging sheet.
The ears (18) and (18) of the packaging sheet project in a triangular or substantially trapezoidal shape at both ends on the bottom side of the packaging rice ball (Patent Document 1). The ears (18) and (18) are inevitably formed when the triangular rice ball is wrapped in the procedure described later because the width of the packaging sheet is larger than the width of the bottom of the triangular rice ball. It is.

JP 2002-354996 A

When packing factory-produced rice balls into packing boxes for over-the-counter shipping, the ears (18) and (18) of the packaging rice balls become an obstacle. Further, when the packaging rice balls are arranged on the display shelf, the packaging rice balls adjacent to each other on the left and right are arranged so as to come into contact with each other, so that the ears (18) and (18) also become an obstacle.
In particular, when one of the rice balls that are adjacent to each other in the horizontal direction with the triangular surface in front is on the ear (18) of the other rice ball, Rice balls may fall down and become deformed. If the rice balls that are adjacent in the horizontal direction are displayed at an interval so as not to be placed on the ear portion (18) of the other rice ball, the number of rice balls that can be displayed is reduced.

In addition, if the ear (18) is carelessly picked and lifted, or if the ear (18) is caught by a protrusion, the severable part (12) of the packaging sheet is perforated (17), (17) tears easily, unpacking, and no longer becomes a product.
The ear (18) is closed by heat welding from the front and back so that the ear does not open its mouth in order to prevent the insertion of foreign matter from the ear and the entry of outside air. However, when the ear portion (18) is sandwiched between the heat welding devices, the ear portion (18) is fluttered and positioning is difficult, and the welding sometimes fails.
This invention provides the packaging rice ball which can solve the said problem, and can prevent the shape change of a triangular rice ball rice.

  In the present invention, a triangular rice ball rice (3) is positioned at a substantially central portion in the longitudinal direction of the packaging sheet (1) with respect to the substantially rectangular packaging sheet (1), and one end side of the packaging sheet (1) is a triangular rice ball. It covers one triangular surface (31) and the side surface in the thickness direction of the rice (3), and both sides of the one end overlap the inner surface of the other end of the packaging sheet (1), and the other end of the packaging sheet (1) The triangle rice ball rice (3) overlaps the other triangular surface (32) and the side surface in the thickness direction, so that both sides of the other end overlap the triangular surface (31) opposite to the triangular surface (32). The wrapping sheet (1) is folded and formed at both ends on the bottom side of the triangular rice ball (3) in a wrapping triangular rice ball having a severable part (12) for dividing the sheet (1) into two in the width direction. The ears (18) and (18) of the packaging sheet (1) are folded back to the bottom surface side and joined by welding or the like.

Wrapping rice balls (5) are formed on the bottom side of the triangular rice ball rice (3), and the ears (18) and (18) of the sheet are folded back to the bottom side and locked by welding or the like. Therefore, the ear (18) does not get in the way when packing rice balls are packed in a returnable box or displayed on a display shelf. There is no problem caused by the adjacent rice balls placed on the ears (18) of the other rice balls.
In addition, there is no risk of inadvertently picking the ear part (18), and the ear part (18) will not be caught by the projection, so even if the separable part (12) is a perforation (17) Unintentional unpacking can be prevented.

  Furthermore, by folding back and joining the ear part (18) to the bottom part of the packaged rice ball (5), both ends of the bottom part of the packaged rice ball are reinforced, and the both ends of the bottom part of the rice ball hit the adjacent rice balls on the display shelf. Even if they are arranged, it is possible to prevent the bottom ends of the packaged rice balls from being out of shape and prevent the product value from being lowered. Further, the ear part (18) does not open its mouth by folding the ear part (18), so that it is possible to prevent foreign matter from being inserted through the ear part (18) and the inflow of outside air.

  When the ear portion (18) is welded and joined to the bottom surface of the rice ball, the ear portion (18) is pressed against the bottom surface of the rice ball and can be reliably positioned and welded, so that it is possible to prevent the welding from failing.

FIG. 1 shows an example of a known packaging sheet (1) used in the present invention, and FIG. 3 is an exploded view thereof.
The packaging sheet (1) has a sheet-like food (2) sandwiched between an outer film (11) and an inner film (14), and the outer periphery of both films (11) and (14) and the sheet-like food (2 ) And the two films (11) and (14) are thermally welded (10) to each other.

  As shown in FIG. 2, the inner film (14) is formed by superposing two film pieces (15) and (16) on their inner edges along the longitudinal direction.

  In the center of the width of the outer film (11), intermittent cuts called so-called perforations (17) are made in the longitudinal direction, and the outer film (11) is cut along the longitudinal direction so that it can be divided into two in the width direction. A possible part (12) is formed.

  The sheet-like food (2) is a sheet-like seaweed (21) in the embodiment, but is not limited to this, and any type can be used as long as it is a food that can be folded in a sheet form.

FIG. 4 shows a state in which triangular rice ball rice (3) is placed on the inner film (14) surface of the packaging sheet (1).
The triangular rice ball rice (3) of the example has an isosceles triangle in which the height Y is larger than the width X at the bottom, and the thickness gradually decreases from the bottom to the top as shown in FIG. ing.

  The length L of the packaging sheet (1) is slightly larger than the length obtained by adding the bottom thickness Z of the triangular rice ball (3) to twice the height Y of the triangular rice ball (3). The width W of the outer film (11) has a sufficient margin with respect to the width length X of the bottom of the triangular rice ball rice (3).

  As shown in FIG. 4, the triangular rice ball rice (3) is packaged in such a manner that the bottom surface of the triangular rice ball rice (3) is positioned substantially at the center in the longitudinal direction of the packaging sheet (1). As shown in FIG. 5, one end side (1a) of the packaging sheet (1) is placed on one triangular surface (31) and the side surface in the thickness direction of the triangular rice ball (3), and both sides of the one end side (1a) ( 1a ′) (1a ′) is placed on the inner surface of the other end (1b) of the packaging sheet (1). The other end side (1b) of the packaging sheet (1) is covered with the triangular surface (32) opposite to the triangular surface (31) of the triangular rice ball (3) and the side surface in the thickness direction, and the other end side. Both sides (1b ′) and (1b ′) of (1b) are folded so as to overlap on the triangular surface (32) opposite to the triangular surface (32). On the triangular surface (31), the label (4) is attached to the folded end of the sheet, or the folded end is fixed by heat welding.

Since the width W of the wrapping sheet (1) is longer than the width length X of the bottom of the triangular rice ball (3), the edges of the wrapping rice ball (5) have triangular or trapezoidal ears ( 18) (18) protrudes.
The ears (18) and (18) are folded back to the bottom surface and joined by spot heat welding or the like.
In the embodiment, as shown in FIG. 10, heat welding (18a) is performed so that the substantially middle portions of the two inclined sides of the substantially triangular ear portions (18) and (18) can be peeled linearly across the sides. (18a). The tips of the ears (18) and (18) remain unwelded, and the unwelded part (18b) can be picked with fingers.

However, the packaged rice balls (5) are folded on the bottom side of the packaging sheet (1) produced at both ends on the bottom side of the triangular rice ball rice (3) and locked by welding or the like. In addition, since it does not protrude outwardly, the ear portion (18) does not get in the way when packing rice balls are packed in a returnable box or when the display shelf is displayed without a gap in the lateral direction with the triangular surface facing forward.
In addition, there is no fear of picking the ear part (18) carelessly, and the ear part (18) will not be caught by the protrusion, so even if the separable part (12) is a perforation (17), It is possible to prevent the packaging from being unraveled.

  Furthermore, by folding and joining the ears (18) to the bottom of the packaging rice balls, both ends of the bottom of the packaging rice balls are reinforced, and the bottom ends of the rice balls are placed on the display shelf so as to hit the right and left adjacent rice balls. Moreover, it can prevent that the both ends of the bottom part of a packaging rice ball lose shape, and can reduce a commercial value.

To unwrap the packaged rice ball (5), the tip side unwelded part (18b) of the ears (18) and (18) is picked, the thermal weld (18a) is peeled off and pulled outward.
The outer film (11) is split into two at the perforation (17) and can be pulled out together with the film pieces (15) and (16) of the inner film (14) which are separated into two parts from the beginning. Only the sheet-like seaweed (21) remains and directly covers the triangular rice ball (31).
Like the example, the tip of the ear (18) is the unwelded portion (18b), and the thermal weld (18b) of the ear (18) can be peeled off, so that the tip of the ear (18) is picked. It can be easily unwrapped by pulling outwards.

  In the case of the embodiment, the triangular onigiri rice (3), that is, the packaging rice ball (5) has a small thickness on the top side, and as shown in FIG. Even if the bottom of (5) presses a little so that the box (6) is filled, a gap S is formed between the upper parts of adjacent packaging rice balls (5) and (5), and the contact area between the rice balls is large. small. For this reason, a finger can be put in from the gap S between the packaged rice balls (5) and (5), and the rice balls can be picked up easily, thereby preventing the rice balls from being out of shape.

  Triangular rice ball rice (3), that is, wrapped rice ball (5), has a height Y up to the top rather than a width X at the bottom, so the width and height of the conventional bottom are almost the same. Compared to the packaged rice ball (5a), it can be differentiated from the conventional product and stimulates purchase.

  In carrying out the present invention, the packaging sheet (1) may be a multi-layer packaging sheet in which the sheet-like food (2) is sandwiched between the outer film (11) and the inner film (14) as described above. Alternatively, a single packaging sheet (outer film (11) in the embodiment) may be used.

  The severable portion (12) of the outer film (11) is bonded to a thin tape called a cut tape at the center of the width of the outer film (11) over the entire length of the outer film (11), and one end of the cut tape The outer film (11) may be cut along the longitudinal direction by pulling the, so as to be possible in the width direction for 2 minutes.

  In addition, the outer film (11) is a directional film that is easy to tear in the longitudinal direction, and two short cuts (not shown) are applied to the central part on one end, and the extension of the cut is the total length of the outer film (11). It can also be a splittable part.

  It should be noted that, when implementing the present invention, as in the conventional examples shown in FIG. 12 and FIG. 13, it can be implemented even with a rice ball that has a substantially equilateral triangle when viewed from the front and has the same thickness from the bottom to the top. is there.

  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. Moreover, each part structure of this invention is not restricted to the said Example, A various deformation | transformation is possible within the technical scope as described in a claim.
