JP 2002-125606 A

The wrapping cone-shaped rice squeezes the wrapping film on the enlarged end of the cone-shaped rice lump and heat-shrinks the outer film. However, since the inner film does not heat shrink and wrinkles are generated, the tool cannot be seen well, and the heat shrink of the outer film causes the tool to be pressed down and deformed, thereby impairing the commercial value.
This invention clarifies the packaging cone-shaped rice which can solve the problem of the said patent document 1. FIG.

Claim 1 is that a substantially conical rice is formed by a packaging sheet (1) formed by sandwiching a sheet-like food (4) between a substantially fan-shaped outer film (2) and a substantially triangular inner film (3). A wrapping cone-shaped rice wrapping the mass (5),
The outer film (2) is transparent and has a severable part (21) for cutting the outer film from the substantially central part of the curved edge (23) to the main side of the fan shape.
The inner film (3) is formed in an approximately isosceles triangle as a whole by superimposing the inner edges of two film pieces (31) (31) having substantially the same shape.
Two sides (32) and (32) having the same length of the inner film (3) are welded so as to overlap the two sides (22) and (22) forming the fan angle of the outer film (2). The inner film does not overlap the curved edge (23) side of 2)
Wrap the packaging sheet (1) around the conical surface of the rice lump (5) with the top of the substantially conical rice lump (5) positioned in the vicinity of the fan-shaped portion of the packaging sheet (1). The transparent outer film (2) of the packaging sheet (1) protrudes from the peripheral edge so that three or four points at substantially equal intervals on the curved edge (23) of the protruding portion of the outer film (2) are close to each other. In the pulled state, the curved edge (23) of the transparent outer film (2) is welded, and three or four welding edges (11) are radially crossed,
A room space (6) exists between the welded portion of the curved edge (23) of the transparent outer film (2) and the enlarged end surface of the conical rice cake (5).

  Claim 2 is the wrapping cone-shaped rice according to claim 1, wherein the cone-shaped rice lump (5) is provided with a tool (7) protruding into the room space (6), and the transparent outer film (2) The tool (7) can be seen through.

  Claim 3 is the packaging cone-shaped rice according to claim 1 or 2, wherein the inner film (3) is entirely embossed.

Since the room space (6) is formed by the transparent outer film (2) on the enlarged end surface of the cone-shaped rice lump (5), the packaging cone-shaped rice of Claim 1 is made from the enlarged end surface. Even when 7) is raised, it is possible to prevent the tool (7) from being damaged, such as causing the tool (7) to lose its shape.
