[0022] For example, the upper portion 2 is formed in the shape of a
bottomed cylinder having a top surface that closes an upper end
portion of the side surface 21, and the side surface 21 provided in
a near perpendicular direction with respect to the top surface.
[0023] Furthermore, as illustrated in FIG. 2 (a) through FIG. 2
(c), the lower portion 3 is formed in the shape of a bottomed
cylinder having a bottom surface that closes a lower end portion of
the side surfaces including the front side surface 31B (that is, a
side surface 312), and the rear side surface 31A (that is, side
surfaces 311, 313, and 314), and a side surface including the front
side surface 31B and the rear side surface 31A (that is, the side
surfaces 311 through 314) set up in a near perpendicular direction
with respect to the bottom surface.
[0024] As illustrated in FIG. 2 (c), the bottom surface of the
lower portion 3 is formed in a near hexagonal shape in a plan view,
for example. The bottom surface of the lower portion 3 is not
limited to a near hexagonal shape in a plan view, but may be formed
in a near polygonal shape in a plan view, such as a near
quadrilateral shape in a plan view, or a near circular shape in a
plan view, or a near elliptical shape in a plan view.
[0025] As illustrated in FIG. 2 (c) and FIG. 3, the bottom surface
is formed by combining together flaps 32 for forming the bottom
surface, which extend from the front side surface 31B and the rear
side surface 31A (that is, the side surfaces 311 through 314).
[0026] Furthermore, in the lower portion 3, a pair of convex
folding-back portions 4 extending out in the upper direction side
from the front side surface 31B and the rear side surface 31A (that
is, the side surfaces 311 through 314) are provided.
[0027] A first weakened line W1 is provided along a first boundary
line B1 between the upper portion 2 and the convex folding-back
portions 4, and a second weakened line W2 is provided along a
second boundary line B2 in the circumferential direction D2 between
the upper portion 2 and the lower portion 3.
[0028] For example, in the present embodiment, the "weakened lines"
are lines that enable the separation of the upper portion 2 in the
packaging case 1, and may be perforated lines, or micro perforated
lines (perforated lines with the length of a perforation and the
length of a non-perforated portion being in the range of
approximately 0.3 mm to 0.8 mm, respectively), or even fragile
lines formed by weakening the sheet material through the laser
processing, and the like.
[0029] The upper portion 2 and the convex folding-back portions 4
may not be connected in at least a part of the first weakened line
W1.
[0030] Specifically, the first weakened line W1 includes straight
weakened lines W11 and curved weakened lines W12, and the upper
portion 2 and the convex folding-back portions 4 may not be
connected in at least a part of the curved weakened lines W12. For
example, a cutting line that completely passes through the sheet
material in the thickness direction of may be provided in at least
a part of the curved weakened lines W12 (for example, at a position
corresponding to an angular portion of the convex folding-back
portions 4).
[0031] Furthermore, in the lower portion 3, a plurality of convex
rising portions 6 extending out in a lower direction from the front
side surface 31B and the rear side surface 31A (that is, the side
surfaces 311 through 314) are provided. The plurality of convex
rising portions 6 are provided at equal intervals. According to the
configuration, the effect of stable rise of the packaging case 1 is
achieved.
[0032] Furthermore, in the upper portion 2, a finger grip portion 5
is provided along a part of the first weakened line W1 and the
second weakened line W2. Furthermore, a hole 10 is provided in the
upper end portion of the side surface 21 of the upper portion 2 in
order to suspend the packaging case 1 from the product display
shelves.
[0033] Furthermore, the packaging case 1 is covered with a paper
sleeve. The sleeve covers at least a part on the outer side of the
packaging case 1, and a locking mechanism is provided in at least
one or more places in the sleeve such that the packaging case 1
does not move from its position during product transport or during
display over the counter.
[0034] A claw shape is provided in the sleeve, and a cut for
inserting the sleeve is provided in the packaging case 1. By
pushing in the claw shape in to the cut, the packaging case 1 and
the sleeve are configured to be locked.
[0035] FIG. 3 is an exploded view of the sheet material used to
form the packaging case 1. The sheet material is particularly not
limited, and a conventional well-known material can be used.
Polyolefins such as polypropylene and polyethylene, synthetic resin
sheets such as polyethylene terephthalate, thick paper, synthetic
paper, and laminated sheets thereof can be used as the sheet
material. The thickness of the sheet is not particularly limited,
and preferably is in the range of approximately 0.2 mm to 1.0
mm.
[0036] As illustrated in FIG. 3, a first folding ruled line Y1 is
provided in the circumferential direction D2 between the convex
folding-back portions 4 and the lower portion 3, and second folding
ruled lines Y2 extending continuously in the vertical direction D1
from between the front side surface 31B and the rear side surface
31A of the lower portion 3 are provided inside the convex
folding-back portions 4.
[0037] The second folding ruled lines Y2 are provided across the
upper portion 2, the convex folding-back portions 4, and the lower
portion 3.
[0038] In the present embodiment, the "folding ruled line" implies
a line formed to enable shaping of the sheet material to facilitate
its folding. The folding ruled line may be, for example, a pressed
line formed by pressing the sheet material in the thickness
direction, or a half-cut line formed by cutting the sheet material
in an almost V shape in the thickness direction.
[0039] In the sheet material illustrated in FIG. 3, after pasting a
tab for sticking 33, which extends towards a side of the side
surface 311, to a side of the side surface 314, while folding the
side surfaces 21, and 311 through 314 along the second folding
ruled lines Y2, the flaps 32 for forming the bottom surface are
combined together to form the packaging case 1.
[0040] As illustrated in FIG. 1, at the time of displaying or
selling the product, the product is configured to be stored inside
the upper portion 2 and the lower portion 3. In the example
illustrated in FIG. 1, a cleaning tool X having a hand grip X1 and
a dust suction portion X2 is configured to be stored inside the
upper portion 2 and the lower portion 3.
[0041] As illustrated in FIG. 1, the cleaning tool X is fixed
inside the packaging case 1 with a fixing mount 11. The fixing
mount 11 is configured by a coat paper or a synthetic resin sheet,
and the dust suction portion X2 and the hand grip X2 are configured
to be set on the fixing mount 11.
[0042] The front side surface 31B of the lower portion 3 includes a
single curved surface (side surface 312), and a pressing ruled line
is not provided inside the front side surface 31B of the lower
portion 3. According to the configuration, the product packaged in
the packaging case 1 can be easily seen from outside.
[0043] Furthermore, as illustrated in FIG. 4, after separating the
upper portion 2 of the packaging case 1, the consumer folds back
the convex folding-back portions 4 towards the inside or the
outside of the lower portion 3, along the first folding ruled line
Y1 or the second folding ruled lines Y2, and as a result, as
illustrated in FIG. 5, the cleaning tool X that has been used once
can be stored inside the lower portion 3.
[0044] According to the packaging case 1 of the present embodiment,
separating the upper portion 2 along the first weakened line W1 and
the second weakened line W2, and then folding back the convex
folding-back portions 4 towards the inside or the outside of the
lower portion 3, along the first folding ruled line Y1 or the
second folding ruled lines Y2 enables the formation of a storage
sheet for the cleaning tool X.
[0045] Furthermore, according to the packaging case 1 of the
present embodiment, by pulling up the finger grip portion 5
provided in the upper portion 2, the consumer can separate the
upper portion 2 easily.
[0046] Furthermore, according to the packaging case 1 of the
present embodiment, by processing the curved weakened line W12 that
is at the position corresponding to the shoulder portion of the
convex folding-back portions 4 as the cutting line, the consumer
can easily separate the upper portion 2.
[0047] According to the packaging case 1 of the present embodiment,
by separating the upper portion 2 and then folding back the convex
folding-back portions 4 towards the outside of the lower portion 3,
along the first folding ruled line Y1 or the second folding ruled
lines Y2, the aperture portion of the lower portion 3 can be
maintained in a stable state.
Second Embodiment
[0048] With reference to FIG. 6, the packaging case 1 according to
a second embodiment of the present invention will be described. The
packaging case 1 according to the present embodiment will be
