Case Unit

Abstract

A case unit C1 includes a case 1 which includes a front surface 11 formed with a take-out opening 19 for taking out an article stored in the case, a cover 2 including a sealing portion 21 for closing the take-out opening 19, and guiding means 30, 31 for enabling the cover 2 to slide relative to the case 1 so that the sealing portion 21 moves reciprocally along the front surface 11. When the sealing portion 21 is positioned in front of the take-out opening 19, the guiding means 30, 31 displaces the sealing portion 21 toward the front surface 11 so that the sealing portion 21 is pressed against the periphery of the take-out opening 19. With this arrangement, the opening and closing of the take-out opening 19 is performed smoothly and easily, and the take-out opening 19 is properly closed even when the sealing portion 21 is worn out. Further, the case unit C1 is suitable for reduction in size and weight.

Description

TECHNICAL FIELD[0001]The present invention relates to a case unit for storing an analytical tool for analyzing a sample such as blood or urine or other articles in hygienic conditions.BACKGROUND ART[0002]FIGS. 8A, 8B, 9A and 9B show examples of conventional case unit for storing an analytical tool (see FIGS. 2A-2C, 3A-3C, 14A and 14B of International Publication WO2006 / 046701).[0003]The case unit 9A shown in FIG. 8A includes a case 90 for storing an analytical tool. The case 90 has a front surface formed with a take-out opening 91. A cover 93, which is in threading engagement with a screw shaft 92, is mounted to the case 90. The cover 93 is movable in the axial direction of the screw shaft 92 by rotating around the screw shaft 92. The cover 93 includes a sealing portion (not shown) made of an elastic material. As shown in FIG. 8B, when the sealing portion faces the take-out opening 91 as a result of the rotation of the cover 93 in the arrow N10 direction, the take-out opening 91 is ...

AI Technical Summary

Benefits of technology

[0008]An object of the present invention is to provide a case unit which is capable of reducing or alleviating the problems described above.

[0013]Preferably, when the sealing portion is spaced from the take-out opening, the guiding means keeps the surface of the sealing portion inclined at an angle of inclination which is larger than the angle of inclination of the tapered surface. When the sealing portion is moved to a position in front of the take-out opening to close the take-out opening, the guiding means rotates the cover so that the surface of the sealing portion becomes parallel with the tapered surface.

[0016]Preferably, the guide projection extends in the longitudinal direction of the guide groove. When the sealing portion moves while being spaced from the take-out opening, at least longitudinally opposite ends of the guide projection are held in contact with one of the front inner wall and the rear inner wall, whereas a longitudinally intermediate portion of guide projection is held in contact with the other one of the front inner wall and the rear inner wall, so that posture of the cover is substantially maintained.

Problems solved by technology

Further, when the sealing portion is worn out, the sealing performance deteriorates.

Thus, the case unit 9B is not suitable for reduction in size and weight.
