  The present invention is a cut cake packaging bag having a form suitable for packaging a substantially wedge-shaped cut cake (including a triangular prism-shaped cake or confectionery), and a cut cake packaging having a triangular prism-shaped storage space when unfolded. Bag.

  As a trunk | drum film and a fold film used when manufacturing the bag for cut cake packaging of this invention, the well-known laminated | multilayer film or single-piece | unit film which can be bag-formed by a heat seal or a fusing seal | sticker can be used.

Hereinafter, Example 1 of the bag for packaging a cut cake embodying the present invention will be described.
As shown in FIGS. 1 to 5, this cut cake packaging bag 10 has two long sides L (corresponding to AF and EF shown in FIG. 1) and one short side S (corresponding to AE shown in FIG. 1). ) And a bottom surface portion 1 having a substantially isosceles triangular shape.

  The cut cake packaging bag 10 is composed of a single film made of biaxially oriented polypropylene (OPP) having a thickness of 30 microns, and the inner width of the folded cut cake packaging bag 10 (see FIG. 1). The fold portion 2 having a length of about 38% of the distance between AFs shown) is provided only on the short side.

  The apex angle θ of the chevron-shaped heat seal H formed at the bottom end of the cut cake packaging bag 10 in a state where the cut cake packaging bag 10 is folded is about 124 degrees, and the substantially wedge-shaped cut cake K is A storage space 3 having a substantially isosceles triangular prism shape suitable for packaging is provided when unfolded (see FIGS. 2 to 5). In the first embodiment, the width of the heat seal H is 5 mm, but may be appropriately selected from a range of about 3 to 6 mm.

The full width (outside dimension) of the cut cake packaging bag 10 in the folded state in the cut cake packaging bag 10 of Example 1 is 115 mm, and the length of the folding portion 2 (the length between AC shown in FIG. 1) is The inner dimension width (the length between the DFs shown in FIG. 1) in a deployed state is 42 mm, and is approximately 102 mm.
Here, the angle formed between the side 4 (inside the heat seal H) of the cut cake packaging bag in which the folding part 2 is not formed and the heat seal H at the bottom is 90 degrees + α.
Then, the magnitude | size of the vertex angle of the isosceles triangle formed in the bottom part of the expand | deployed cut cake packaging bag 10 will be about 2 (alpha) (angle | corner AFE).

Further, the angle formed between the side 5 of the cut cake packaging bag 10 in which the folding part 2 is formed and the heat seal H at the bottom is 90 degrees + β.
Then, since the triangle ABC and the triangle ABD are congruent,
2β = 90 degrees−α (Expression 1)

The apex angle θ of the chevron-shaped heat seal formed at the bottom end of the folded cut cake packaging bag 10 is apex angle θ = 180 degrees−α−β.
If Expression 1 is substituted for this, the vertex angle θ = 135 degrees−α / 2 (Expression 2).
