Further, the depth of the housing accommodating portion 36 (depth from the intermediate portion 34 to the bottom portion 36e) is formed to be larger than the thickness of the housing 20 (thickness from the front surface 20a to the back surface 20b). The entire housing 20 is housed in the housing housing portion 36.

A plurality of side wall convex portions 40a to 40d are provided on the side wall portions 36a to 36d of the housing accommodating portion 36. Further, the bottom portion 36e is provided with a plurality of impact mitigating convex portions 42. The side wall convex portions 40a to 40d and the impact mitigation convex portion 42 are formed by inflating the resin sheet constituting the side wall portions 36a to 36d and the bottom portion 36e of the housing accommodating portion 36 toward the inside of the housing accommodating portion 36. It extends in a rib shape in a predetermined direction.

The side wall portion 36a is provided with two side wall convex portions 40a at a portion closer to the side wall portion 36c and a portion closer to the side wall portion 36d. Further, the side wall portion 36b is provided with two side wall convex portions 40b. The two side wall convex portions 40a and the two side wall convex portions 40b are provided so as to face each other in the width direction. The side wall portion 36c is provided with one side wall convex portion 40c, and the side wall portion 36d is provided with two side wall convex portions 40d.

As shown in FIG. 1, each of the side wall convex portions 40a to 40d is formed so as to extend in the depth direction (vertical direction) of the housing accommodating portion 36. The side wall convex portions 40a to 40d are formed in a semicircular cross section, and the ridge line portion L thereof contacts (line contact) with the housing 20.

As shown in FIG. 2, the distance D1 between the side wall convex portion 40a of the side wall portion 36a and the side wall convex portion 40b of the side wall portion 36b is slightly smaller than the widthwise dimension of the housing 20. Further, the distance D2 along the long side direction between the side wall convex portion 40c of the side wall portion 36c and the side wall convex portion 40d of the side wall portion 36d is smaller than the dimension in the long side direction of the housing 20. Therefore, the housing 20 is held in a state of being sandwiched by the side wall convex portions 40a to 40d in the housing housing portion 36.

Four impact mitigation protrusions 42 are formed on the bottom portion 36e. The impact mitigation convex portion 42 is provided so as to extend from the lower ends of the side wall convex portion 40a and the side wall convex portion 40b toward the center in the width direction in a rib shape. The impact mitigation convex portion 42 is divided at the divided portion 44 near the center in the width direction.

The impact mitigation convex portion 42 is configured to have a curved surface whose upper end is curved, and is configured to make line contact with the front surface 20a of the housing 20 at its ridgeline portion L. Each impact mitigation convex portion 42 is formed by being integrally connected to the adjacent side wall convex portion 40a or the side wall convex portion 40b.

The width W (dimension in the direction perpendicular to the extending direction) of the side wall convex portions 40a to 40d and the impact mitigation convex portion 42 can be, for example, about 3 to 10 mm. If the width W is smaller than the above lower limit value, the resin sheet constituting the container body 16 cannot be sufficiently deformed when the impact load is input, and the impact load mitigation performance is deteriorated. Further, when the width W is larger than the above upper limit value, there is an increased possibility that an obstacle at the collision site enters the side wall convex portions 40a to 40d and the impact mitigation convex portion 42, and the impact is directly input to the housing 20. ..

The cross-sectional shapes of the side wall convex portions 40a to 40d and the impact mitigation convex portion 42 are not limited to a semicircular shape, but are various curved shapes and polygonal shapes that are in line contact with the housing 20 or a narrow linear region close to the housing 20. It may be made to abut with.

A gap is formed between the housing 20 and the side wall portions 36a to 36d according to the protruding height of the side wall convex portions 40a to 40d. In order to prevent the user from touching the fragile portion of the drug solution administration device 12 when the housing 20 is removed from the container body 16, the protruding heights of the side wall convex portions 40a to 40d are set by the user's fingers.

The separating portion 33 is separated by a distance that does not stick to the sealing film 18 (FIG. 1) due to static electricity, moisture, or the like, and is maintained in a state of being separated from the sealing film 18. The gap between the separating portion 33 and the sealing film 18 forms a knob allowance that is easy for the user to grip when the sealing film 18 is peeled off.

The container body 16 is formed of, for example, a transparent resin sheet such as PET resin. The thickness of the resin sheet of the container body 16 is preferably relatively thick, for example, about 0.8 mm. If the thickness of the resin sheet is too thin, the strength of the container body 16 is insufficient, and the chemical solution administration device 12 cannot be protected from the impact when dropped. Further, if the thickness of the resin sheet is too thick, the strength and rigidity of the side wall convex portions 40a to 40d and the impact mitigation convex portion 42 become too high, and it becomes difficult to alleviate the impact when dropped.

As shown in FIG. 1, the sealing film 18 is formed in a rectangular shape having substantially the same dimensions as the container body 16. The sealing film 18 is made of a thin and flexible film made of, for example, polyethylene resin. The sealing film 18 is adhered to the sticking portion 32 so as to cover the recess 14 and the intermediate portion 34 from the upper side of the container main body 16 to seal the chemical solution administration device 12. The sealing film 18 is bonded so as to be peelable by sandwiching the bonded portion with a mold in a state of being overlapped with the bonded portion 32 and locally heating the sealing film 18 to fuse them.
