[Industrial applications]

 The present invention relates to a container opening device that can remove a rubber plug fitted into an opening of a container such as a container without touching the container, and in particular, opening the container by restricting movement of the container during opening. The present invention relates to an opening device capable of surely performing a plugging operation.

[Prior art and its problems]

 As is well known, a rubber container such as a vacuum blood collection tube is fitted with a rubber stopper in its opening for the purpose of preventing the outflow of a blood sample.

By the way, the rubber stopper is removed, for example, when the container is set in an automatic analyzer, but the removal of the rubber stopper is conventionally performed manually.

However, when the rubber stopper is manually removed, there is a risk that the blood sample collected may come into contact with various diseases, and the rubber stopper should be removed in a large number of containers. Since it is carried out for such a case, there is a problem that such a work is very complicated and there is a risk of blood contact infection even when collecting the extracted rubber stoppers.

Therefore, the present applicant first removes the rubber stoppers of a plurality of containers in one operation without touching them, and collects the discarded rubber stoppers without shaking and discards them. A cap opening device for a container or the like that has a simple structure is proposed (Japanese Patent Application No. 3-40444).

[0006] The opening device for a container or the like according to the applicant's earlier application includes a base member, a support member provided upright on the base member, and a pivotally rotatably mounted on an upper portion of the support member. Mounted on a container or the like pulled out by the locking piece by rotating the rotating member, and the locking piece connected to the front edge of the rotating member. And a plug receiving pad for dropping and storing the rubber plug.

[0007] By the way, most of the containers carried into the specialized inspection center have different outer diameters and the like. For such a container, the container opening device of the above-mentioned applicant's earlier application is used. If the locking piece is hooked on the rubber plug and then the rotating member is rotated, a reaction force opposite to the rotating direction of the rotating member is applied to the lower half of the rack. There is a problem in that the container may float up from the rack and the rubber stopper may not be able to be pulled out.

The present invention has been made in view of the above situation, and an object thereof is to prevent a rubber stopper from being opened from a container opening by an opening means without pressing the container by hand. An object of the present invention is to provide an opening device capable of reliably removing a rubber plug.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, a rack set at a predetermined opening position of a base member, a container erected upright on the rack, and a liquid-tight seal at the upper end opening of the container. The technical premise is an uncapping device having a rubber plug fitted to the rack and means for opening the rubber plug at the uncapping position. It is characterized in that a window portion for opening and retracting the anti-floating body for pressing the body portion of the container held in the opposite direction from the opposite direction is opened.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

As shown in FIG. 1, a cap opening device 1 according to this embodiment has a flat plate-shaped base member 2 having a rubber mat 3 adhered to the lower surface thereof, and both front end portions of the base member 2. On the upper surface of the base member 2, there are provided a pair of upright supporting members 4, 5, a rotating member 7 which is rotatably supported on the upper portions of the supporting members 4, 5 via a shaft 6. The plug receiving pad 8 is detachably attached.

The base member 2 is configured to have a space for accommodating the rack 15 in which the containers 14 and the like are erected, on the front side of the portion where the supports 4 and 5 are erected. The container 14 and the rack 15 are set in the above space from the front side of FIG.

On the other hand, the rack 15 has a main body formed in a substantially concave front shape, and holding plates 15a and 15b are provided on upper and middle portions of the main body, and the holding plates 15a and 15b are provided. A plurality of container insertion holes 15c are opened at predetermined intervals along the longitudinal direction of the container.

A free-size container holder H is fitted in the container insertion hole 15c, and the container holder H includes a ring-shaped base body 20 and this base body as shown in FIG. It is composed of a substantially V-shaped bullet piece 21 formed so as to hang down at predetermined intervals along the circumferential direction of 20 and biased inwardly.

Therefore, even if the diameter of the body of the container 14 is different from the diameter of the container insertion hole 15c, the substantially V-shaped bullet piece 21 makes elastic contact with the body of the container 14 and the container 14 is racked. It can be held vertically at 15.

Further, as shown in FIG. 1, the rack 15 is configured to have windows 15d and 15e whose front and rear sides are open, and from the upper window 15d, the container 15 can be opened. The floating prevention body 22 that presses the upper half of the body of the container 14 enters from the direction opposite to the rotating direction of the rotating member 7, and the body of the container 14 can be seen from the lower window 15e. An anti-floating body 23 that presses the lower half of the subordinate portion is configured to enter from a direction opposite to the direction in which the anti-floating body 22 enters so that the container 14 does not float by the opening operation. There is.

The rotating member 7 includes a horizontal plate portion 10 and a locking piece portion 11 extending downward from a front edge portion of the horizontal plate portion 10 and having a cross-section formed in a substantially L-shape. The shaft 6 is composed of a support piece 12 extending downward from both ends on the depth side of the horizontal plate 10, and a handle 13 fixed to the upper surface of the horizontal plate 10. It is mounted below each of the support pieces 12.

Further, the rotating member 7 is stopped in a state shown by a solid line in FIG. 1, that is, the horizontal plate portion 10 is stopped in a horizontal state and is rotated so as not to rotate counterclockwise from the horizontal state. It is regulated by a body (not shown). Of course, clockwise rotation in FIG. 1 is not restricted.

The locking piece 11 is a rubber whose locking end 11 a is liquid-tightly fitted in an opening of the container 14 or the like when the rotating member 7 is set in the horizontal state. The stopper 16 is configured to be locked to the step portion 16a. In addition, it is desirable that the locking piece portion 11 is formed so as to have a rigidity that does not bend and deform much.

On the other hand, in the handle 13 fixed to the upper surface of the horizontal plate portion 10, the grip piece portion 13a is attached so as to be inclined in the rotating direction of the rotating member 7, that is, the direction in FIG. 1a.

By tilting the gripping piece 13a of the handle 13 in the rotation direction a of the rotating member 7 in this way, the gripping piece can be operated by the gripping piece with respect to the rotational operation force of the rotating member 7 during unplugging. Compared with the case where it is installed upright vertically, it can be greatly reduced.

The plug receiving pad 8 is formed to have a substantially concave cross-section and a substantially convex planar shape, and the length dimension thereof is such that the rear end portion 8a is fixed to both sides of the rear end portion of the base member 2a. The corner fitting 17 is positioned so as to abut the corner fitting 17, and the front end portion 8b is formed to have a length dimension such that the front end portion 8b is flush with the front end portions of the supports 4 and 5.

The front plate 8c of the plug receiving pad 8 is formed so as to be inclined, and the locking piece portion 11 is engaged with the step portion 16a of the rubber plug 16 so that the shaft 6 can be secured. When the rubber plug 16 is pivoted as a fulcrum and the rubber plug 16 is pulled out, the pulled rubber plug 16 falls by its own weight toward the plug receiving pad 8 and rolls on the inclined surface of the front plate 8c to move the plug receiving pad. It is configured to be housed in the door 8.

Therefore, in the above-mentioned opening apparatus, when the rack 15 is set to the opening position and the rotating member is rotated in the direction of FIG. 1a, the lower end of the container 14 erected on the rack 15 is lowered. A force to rotate the container 14 in the direction of FIG. 1b acts on it, but since the container 14 is restricted from rotating in the direction b by the floating prevention members 22 and 23, the cap 14 is opened. It can be performed stably. Further, since the container 14 is erected and held in the container insertion hole 15c of the rack 15 by the container holder H capable of supporting a free size, the diameter of the body of the container 14 is different from the diameter of the container insertion hole 15c. However, a stable holding state can be obtained.
