Housing box
There is provided a housing box that prevents breakage of a rod-shaped member like a nozzle use for an automatic analyzer at the time of transportation. A housing box in which a rod-shaped member used for an automatic analyzer is housed, the housing box includes: a base provided with a housing part in a groove shape on which the rod-shaped member is placed; and a cover put on the base, wherein the housing part has a step on which a projection is caught, the projection being provided on a bottom of the rod-shaped member, the projection projecting in a radial direction, and a space between a tip end and an inner wall of the rod-shaped member.
1 . A housing box in which a rod-shaped member used for an automatic analyzer is housed, the housing box comprising:
a base provided with a housing part in a groove shape on which the rod-shaped member is disposed; and
a cover connected to the base via a hinge, the cover covering the base,
wherein the groove shape of the housing part includes:
a first groove region, a second groove region, a third groove region and a fourth groove region, which each have different depths in a depth direction, the third groove region being between the fourth groove region and second groove region in a longitudinal direction of the rod-shaped member, and the second groove region having a depth deeper than respective depths of the first groove region, the third groove region and the fourth groove region; and
a step, between the first groove region and the second groove region, on which a projection of the rod-shaped member is caught and which contacts the projection of the rod-shaped member, the projection of the rod-shaped member being in a radial direction with respect to a rod of the rod-shaped member and is provided on an opposite side of the rod-shaped member than a tip end of the rod-shaped member,
wherein the housing part includes a space, within the fourth groove region, that is between the tip end of the rod-shaped member and an inner wall of the housing part within the fourth groove region, the contact of the projection of the rod-shaped member and the step preventing movement of the tip end of the rod-shaped member toward the inner wall of the housing part of the fourth groove region,
wherein the cover has a projection that projects in the depth direction and which spans at least over the third groove region and contacts the rod-shaped member.
2 . The housing box according to claim 1 ,
wherein the cover has two fitting parts that fit in the base upon closing of the cover.
3 . The housing box according to claim 1 ,
wherein a height dimension of the step is greater than a radial dimension of the projection of the rod-shaped member.
4 . The housing box according to claim 1 ,
wherein the housing part has a space confiqured to accommodate entering in a direction orthogonal to the longitudinal direction of the rod-shaped member.
5 . The housing box according to claim 1 ,
wherein the base is provided with a plurality of the housing parts.
6 . The housing box according to claim 1 ,
wherein the cover is essentially rectangular having two long sides extending in a longitudinal direction, and
wherein the cover is provided with a rib perpendicular to the longitudinal direction connecting the two long sides of the cover.
7 . The housing box according to claim 1 ,
wherein the base and the cover are integrally formed by a vacuum forming method together with a hinge connecting the base to the cover.
