  • Patent number: 9370889
    Abstract: A container main body and a cap are stably and detachably engaged while improving a productivity. A leading end portion of a tubular container main body is provided with one or more projection portion on an outer peripheral surface, a hole communicating inner and outer sides of a tube in a rear side in an axial direction of the projection portion, and an expanded portion expanded such that an outer diameter within the tube is equal to or more than an outer diameter of the projection portion and running to a rear side in a rear side in an axial direction of the hole, respectively. An inner peripheral surface of a cap is provided with an annular projection detachably engaging with disengaging from the projection portion in an axial direction. The projection portion securely climbs over the annular projection for its flexibility in a diametrical direction of the hole.
    Type: Grant

  • Patent number: 8277137
    Abstract: To generate a sense of click according to the movement of a moving member, reset screwing sections to screw in when a screwing action of the screwing sections is released, and reduce the number of components. In a container 100, when a main body cylinder 2 and an operation cylinder 3 are relatively rotated in an extending direction and relatively rotated in a retracting direction, a female screw member 5 and a moving member 4 relatively rotate, the moving member 4 moves forward and moves backward according to a screwing action of screwing sections 8, and click teeth 54 and 64 also relatively rotate in synchronization with each other. Since an elastic body 61 urges the click teeth 64 toward the click teeth 54, a sense of click is given when the moving member 4 moves forward and moves backward.
