In the following description, the longitudinal direction of the container body 10, the plate 20, and the toothbrush 50 is the Y direction, and the width direction of the head portion 53 parallel to the flocking surface 51 and perpendicular to the Y direction is the X direction. The direction orthogonal to the direction and orthogonal to the flocking surface 51 will be appropriately described as the Z direction.

FIG. 3 is a partial front view of the vicinity of the head portion 53 in FIG. 2 as viewed from the +Z side.
As shown in FIG. 2, the head portion 53 is elongated in the Y direction, which is the lengthwise direction of the handle portion 55, and has a flat plate shape with a corner cut at the top in a front view. When viewed from the front, the head portion 53 expands outward in the width direction from the tip of the head portion 53 toward the neck portion 54 , then extends with the same width, narrows inward in the width direction, and reaches the boundary with the neck portion 54 . It has a wide range of shapes.

That is, the head portion 53 has protrusions 53a on both sides in the width direction near the boundary with the neck portion 54, the protrusions 53a protruding more than the neck portion 54 in the width direction.

The neck portion 54 integrally connects the head portion 53 and the handle portion 55 .
In this embodiment, the neck portion 54 widens and extends toward the handle portion 55 when viewed from the front.

The handle portion 55 extends from the boundary with the neck portion 54 to the rear end side with a constant width in a front view, and then narrows toward the rear end side. A region of the handle portion 55 extending from the boundary with the neck portion 54 to the rear end side with a constant width is the widest main grip portion in a front view. The handle portion 55, which is narrower on the rear end side than the main grip portion, extends toward the rear end side with a constant width that is narrower than the width on the front end side in a front view. The cross-sectional shape of the handle portion 55 is substantially rectangular.

As shown in FIG. 2, in the toothbrush 50, the head portion 53 has the thinnest thickness indicating the length in the Z direction when viewed from the side in the X direction. The thickness of the toothbrush 50 gradually increases from the head portion 53 to the boundary between the neck portion 54 and the handle portion 55 toward the rear end side. The toothbrush 50 has a maximum thickness at the main grip portion, gradually decreases in thickness toward the rear end, and then extends to the rear end with a constant thickness.

The container body 10 includes a substrate portion 12 having a substantially rectangular shape in plan view, a side wall portion 13 extending from the outer peripheral edge of the substrate portion 12 to the −Z side over the entire circumference, and extending outward from the −Z side end portion of the side wall portion. and a flange portion 14 that extends. The flange portion 14 is parallel to the XY plane.

Examples of the container main body 10 include polyester-based resins, polycarbonate-based resins, polyethylene-based resins, polypropylene-based resins, polystyrene-based resins, and the like, and polyethylene terephthalate resin, which is a polyester-based resin excellent in transparency, can be preferably used.

The substrate portion 12 has a dome portion 11 that protrudes in a dome shape toward the +Z side.
The dome portion 11 is open on the −Z side facing the plate 20 . The dome portion 11 accommodates the toothbrush 50 from the −Z side of the opening. The dome portion 11 accommodates the toothbrush 50 with the bristle-implanted surface 51 and the bristle bundles 52 facing the +Z side.

The dome portion 11 includes a head accommodating portion 43 that accommodates the head portion 53, a neck accommodating portion 44 that accommodates the neck portion 54, and a handle accommodating portion 45 that accommodates the area of the handle portion 55 excluding the rear end portion 55a. and an end accommodating portion 46 for accommodating the rear end portion 55 a of the handle portion 55 .

2, when the toothbrush 50 is accommodated between the dome portion 11 and the plate 20, the head accommodation portion 43 has a height that is separated from the tip of the bristle bundle 52 on the +Z side in a side view. is provided in As shown in FIG. 3, the head accommodating portion 43 is formed with an outer contour that is larger than the outer contour of the head portion 53 when viewed from the front. The head accommodating portion 43 has a contact portion (second contact portion) 43a that contacts the protrusion 53a of the head portion 53 from the -Y side when viewed from the front. Between the contact portion 43a and the plate 20, the container body 10 containing the toothbrush 50 is positioned so that the head portion 53 faces upward (that is, the Y-axis direction is the vertical direction and the +Y side is the upward direction). abuts on the protrusion 53a of the head portion 53 when suspended by the .

When the toothbrush 50 is accommodated between the dome portion 11 and the plate 20, the distance in the Z direction between the neck portion 54 and the neck accommodation portion 44 in a side view is the length of the bristle bundle 52, as shown in FIG. It is set smaller than the distance in the Z direction between the tip and the head accommodating portion 43 . Further, as shown in FIG. 3, when the toothbrush 50 is accommodated between the dome portion 11 and the plate body 20, the distance in the X direction between the neck portion 54 and the neck accommodating portion 44 in front view is is set smaller than the distance in the X direction between the head portion 53 and the head accommodating portion 43 in .

Therefore, in the blister packaging container 1 of this embodiment, the gap between the neck portion 54 and the neck accommodating portion 44 is smaller than the gap between the head portion 53 and the head accommodating portion 43 . Therefore, in the blister packaging container 1 of the present embodiment, movement of the neck portion 54 in the Z direction and the movement in the X direction with respect to the neck accommodating portion 44 are restricted, so that the head portion 53 moves in the Z direction or the X direction. As a result, problems such as deformation of the hair bundle 52 due to contact with the head accommodating portion 43 can be suppressed.

The handle accommodating portion 45 accommodates a portion of the rear end side of the neck portion 54 and the handle portion 55 in a region other than the rear end portion 55a. The width of the handle accommodating portion 45 in the X direction is substantially the same as the width of the substrate portion 12 in the X direction.

FIG. 4 is a partially enlarged view of the end accommodating portion 46 shown in FIG. FIG. 5 is a partial front view of the vicinity of the end accommodating portion 46 in FIG. 2 as viewed from the +Z side. 4 and 5 show a state where the +Y side is the upper side in the vertical direction.
As shown in FIGS. 1, 4, and 5, the end accommodating portion 46 includes a holding portion 47 and a contact portion 48 arranged on the +Z side of the rear end portion 55a, and a rear end portion 55a. and holding portions 49 arranged on both sides in the X direction.

The holding portion 49 is arranged substantially parallel to the YZ plane. The distance in the X direction between each holding portion 49 and the rear end portion 55 a is smaller than the distance in the X direction between the handle housing portion 45 and the handle portion 55 . The X-direction distance between each holding portion 49 and the rear end portion 55a is the same as the X-direction distance between the neck portion 54 and the neck accommodating portion 44 . Therefore, the toothbrush 50 has the neck portion 54 held in the neck accommodating portion 44 in the X direction with a small gap on the front end side, and the rear end side end portion 55a held in the X direction by the holding portion 49 in the rear end side with a small gap. be. Therefore, the toothbrush 50 is held and housed in the dome portion 11 while being positioned in the X direction and extending in the Y direction.

As shown in FIG. 4, the holding portion 47 is substantially parallel to the XY plane. The distance in the Z direction between the holding portion 47 and the rear end portion 55 a is smaller than the distance in the Z direction between the handle housing portion 45 and the handle portion 55 . The Z-direction distance between the holding portion 47 and the rear end portion 55 a is the same as the Z-direction distance between the neck portion 54 and the neck accommodating portion 44 . Therefore, the toothbrush 50 has the neck portion 54 held in the Z direction by the neck accommodating portion 44 with a small gap on the front end side, and the rear end side end portion 55a is held in the Z direction by the holding portion 47 with a small gap on the rear end side. be. Therefore, the toothbrush 50 is held and housed in the dome portion 11 while being positioned in the Z direction and extending in the Y direction.

Between the contact portion 48 and the plate 20, the container body 10 containing the toothbrush 50 is oriented such that the head portion 53 faces upward (that is, the Y-axis direction is the vertical direction and the +Y side is the upward direction). It has an abutment surface 48a that abuts on the rear end portion 55a when suspended from the bottom. That is, when the blister packaging container 1 of the present embodiment is hung with the head portion 53 facing upward, the abutment portion 43a of the head accommodating portion 43 contacts the protruding portion 53a of the head portion 53 on the rear end side ( That is, the contact surface 48a of the contact portion 48 contacts the rear end side end portion 55a from the rear end side (that is, the lower side).

The contact surface 48a is inclined toward the plate 20 from the -Y end of the holding portion 47 toward the rear end (-Y side). The contact surface 48a is inclined around the X-axis at an intersection angle θ with respect to a plane parallel to the XZ plane perpendicular to the length direction of the handle portion 55 .

The plate 20 has the same contour as the container body 10 . The plate 20 is fixed to the flange portion 14 of the container body 10 by welding, bonding, or the like. Although the material constituting the plate 20 is not particularly limited, for example, various resin sheets or sheets having a paper material as a sheet base material can be used. When the sheet base material is a paper material, examples thereof include cardboard made of paper only, and synthetic paper obtained by coating a paper sheet with various resins or pasting a resin sheet or vapor-deposited sheet.

As shown in FIG. 1, the blister packaging container 1 has a notch 60 formed by notching the container body 10 and the plate 20 and penetrating in the Z direction. The notch portion 60 is provided on the +Y side of the head accommodating portion 43 . The notch 60 has a first notch 61 and a second notch 62 .

One end of the first notch 61 is open at the edge of the container body 10 and the plate 20 on the -X side. The first notch 61 gradually extends toward the +Y side as it moves toward the +X side. The second notch 62 extends from the other end of the first notch 61 toward the +Y side. The +Y side end of the second notch 62 is an arc portion whose center is located on the -Y side. The center position of the arc portion is arranged on a straight line extending in the Y direction and passing through the center of gravity of the blister packaging container 1 containing the toothbrush 50 .

For example, the blister packaging container 1 configured as described above is made by inserting a shaft member such as a metal fitting extending in the Z direction in the storefront into the second notch portion 62 from the -Z side and engaging with the arc portion. The container body 10 containing the toothbrush 50 is displayed in a state of being suspended with the head part 53 facing upward.

Also, the blister packaging container 1 is relatively moved from the +X side to the -X side, and the shaft member such as a fitting extending in the Z direction is moved from the first notch 61 to the second notch in a direction perpendicular to the axis. It can be introduced at 62 and engaged with the arc. Since the center position of the circular arc portion is arranged on a straight line extending in the Y direction passing through the center of gravity of the blister packaging container 1 containing the toothbrush 50, the toothbrush 50 is suspended in the vertical direction in the blister packaging container. The packaging container 1 can be displayed.

When the blister packaging container 1 is suspended, the contact portion 43a of the head accommodating portion 43 contacts the protrusion 53a of the head portion 53 from the rear end side (that is, the lower side), and the contact portion 48 contacts. The surface 48a abuts the rear end portion 55a from the rear end side (that is, from below).

For example, when the blister packaging container 1 that is displayed in a suspended state is dropped from a state in which it is suspended with the head portion 53 facing upward, the drop impact is transferred from the protrusion 53a of the head portion 53 to the head accommodating portion 43. is transmitted to the contact portion 43 a of the handle portion 55 and transmitted to the contact surface 48 a of the contact portion 48 from the rear end portion 55 a of the handle portion 55 .

Since the contact surface 48a is inclined in a direction toward the plate body 20 toward the rear end side, the rear end portion 55a slides along the contact surface 48a when dropped. The sliding of the rear end portion 55a increases the area of the abutment surface 48a that contacts the rear end portion 55a when the blister packaging container 1 is dropped (hereinafter simply referred to as drop). Therefore, the drop impact per unit area applied to the contact surface 48a can be reduced.

In addition, of the vertical force of the contact surface 48a generated by the force transmitted from the rear end portion 55a that comes into contact when dropped, the force in the horizontal direction directed to the -Z side has a magnitude corresponding to the crossing angle θ. It joins the rear end side end portion 55a.

For example, the normal force A when the force F is applied to the contact surface 48a when dropped is represented by the following formula (1).
A=F×cos θ (1)
Also, the horizontal component H of the vertical force A is represented by the following equation (2).
H=A×sin θ (2)

Therefore, the force H55 in the horizontal direction directed to the -Z side applied to the trailing end portion 55a when dropped is expressed by the following equation (3).
H55=F×cos θ×sin θ (3)

Due to the force H55 represented by the formula (3) being applied at the time of falling, the rear end side end portion 55a moves to the -Z side and abuts on the plate 20. FIG. When the rear end portion 55a comes into contact with the plate 20 when dropped, the plate 20 bears part of the drop impact. That is, the plate 20 bears part of the drop impact, so that the drop impact applied to the contact surface 48a can be reduced.

As described above, the crossing angle θ is set to 30° in order to reduce the drop impact per unit area applied to the contact surface 48a when dropped and to increase the force H55 in the horizontal direction directed to the −Z side. Above, it is preferably less than 90°, and more preferably 30° or more and 70° or less.

When the crossing angle θ is less than 30°, the distance that the trailing end portion 55a slides along the contact surface 48a when dropped becomes short, and the force H55 in the horizontal direction becomes small. There is a possibility that the reduction amount of the applied drop impact may not be sufficient. If the crossing angle θ is 90° or more, the contact surface 48a cannot contact the rear end portion 55a.

If the crossing angle θ exceeds 70°, the contact surface 48 a becomes longer in the Y direction than the entire length of the toothbrush 50 , and the length of the dome portion 11 becomes inadequate with respect to the entire length of the toothbrush 50 . It becomes longer than necessary. On the other hand, in order to keep the Y-direction length of the blister packaging container 1 within the specified value, it is conceivable to shift the position of the dome portion 11 in the container body 10 to the +Y side. When the blister packaging container 1 is displayed at the storefront, the necessary space for providing the notch portion 60 cannot be secured.

As described above, in the blister packaging container 1 of the present embodiment, the rear end portion 55a of the handle portion 55 abuts on the dome portion 11, and the abutment tilts toward the plate body 20 toward the rear end side. Since the surface 48a is provided, it is possible to prevent cracks from occurring in the dome portion 11 when the plate body 20 is dropped without degrading the appearance due to deformation of the plate body 20 or the like.

In particular, in the blister packaging container 1 of the present embodiment, the crossing angle θ between the contact surface 48a and the surface parallel to the XZ plane is 30° or more and 70° or less, so that the trailing end portion 55a comes into contact when dropped. When the crossing angle θ is less than 30°, for example, the sliding distance along the contact surface 48a becomes shorter, the force H55 in the horizontal direction becomes smaller, and the reduction amount of the drop impact applied to the contact surface 48a becomes insufficient. The length of the dome part 11 becomes unnecessarily long with respect to the total length of the toothbrush 50, and the appearance deteriorates. When the crossing angle θ exceeds 70°, it is possible to suppress problems such as being unable to be secured.

In addition, in the blister packaging container 1 of the present embodiment, since the contact portion 43a that contacts the protrusion 53a of the head portion 53 from the -Y side is provided in the front view, part of the drop impact is absorbed by the contact portion. Since 43a absorbs, it becomes possible to further suppress the occurrence of cracks in the dome portion 11 when dropped.

[Example]
EXAMPLES The present invention will be described in detail below with reference to examples, but the present invention is not limited to the following examples, and can be carried out with appropriate modifications within the scope of the invention.

(Examples 1 to 6, Comparative Example 1)
In accordance with the specifications shown in [Table 1], the blister packaging containers of Examples 1 to 6 differ in the intersection angle θ between the contact surface 48a and the surface parallel to the XZ plane, and the presence or absence of the contact portion 43a of the head accommodating portion 43. A sample of Example 1 was used. Each sample was analyzed using strength analysis software (LS-DYNA, manufactured by LSTC (USA)). The analysis simulated the maximum stress generated in the contact part 48 of the dome part 11 due to the impact when the blister packaging container containing the toothbrush was dropped from a height of 50 cm, and the contact was determined from the magnitude of the maximum stress. The difficulty of generating cracks in the portion 48 was evaluated. Further, for Example 1, Example 3, and Comparative Example 1, a drop test was also conducted to measure the number of cracks generated in the dome portion 11 when the blister packaging container was dropped from a height of 1 m.

(Evaluation method)
In the simulation results for each sample, samples with a maximum stress value of 19.0 (kgf/mm ² ) or less are evaluated as “OK”, and the maximum stress value is 19.0 (kgf/mm ² ). Samples exceeding 100% were evaluated as "NG", which is NG.

As shown in [Table 1], for the blister packaging container of Comparative Example 1 in which the crossing angle θ is less than 30°, the value of the maximum stress generated by the impact when dropped from a height of 50 cm is the standard. However, it was confirmed that the maximum stress values of the blister packaging containers of Examples 1 to 6, in which the crossing angle θ was 30° or more and 70° or less, were below the reference value. Further, as shown in [Table 1], when the intersection angle θ is the same, the blister packaging container of Example 1 having the contact portion 43a that contacts the protrusion 53a of the head portion 53 from the -Y side, It was confirmed that the maximum stress value was smaller than that of the blister packaging container of Example 3, which did not have the contact portion 43a.

Furthermore, as shown in [Table 1], all the blister packaging containers (12/12) of the blister packaging containers of Comparative Example 1 (12/12) cracked in the dome portion 11 when dropped from a height of 1 m. However, with regard to the blister packaging containers of Examples 1 and 3, it was confirmed that cracks did not occur in the dome portion 11 of all the blister packaging containers.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. The various shapes, combinations, etc., of the constituent members shown in the above examples are merely examples, and various modifications can be made based on design requirements and the like without departing from the gist of the present invention.

For example, the configuration of the toothbrush 50 described in the above embodiment is an example, and the toothbrush housed in the blister packaging container is not particularly limited as long as it has a head portion, a neck portion, and a handle portion.

Further, in the above-described embodiment, the contact surface 48a is an inclined surface parallel to the surface in which the XZ plane is inclined around the X axis, but the configuration is not limited to this. The contact surface 48a may be, for example, an arcuate curved surface with the center located on the -Z side in a side view. In this case, the intersection angle θ may be the angle at which the tangent line at the location where the contact surface 48a contacts the rear end portion 55a intersects with a plane parallel to the XZ plane.
