[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flip-off cap remover, and more particularly, to a flip-off cap used for a small vial containing a solution for injection, a freeze-dried preparation, a dissolution solution, etc., a so-called vial. The present invention relates to a protective cover removing device for a cap.

[0002]

2. Description of the Related Art As is well known, in hospitals and the like, a large amount of chemicals contained in vials is used. Recently, vials with a protective cap called a flip-off cap as shown in FIG. 7 are often used. In FIG. 7, a normal vial has a rubber inner stopper 4 that closes the mouth 3 of the vial 2.
The flip-off cap 1 has the inner stopper 4 and the vial 2
Body 5 that integrally covers the mouth 3 of the vehicle, and a protective cover 6 that is removably attached to the upper portion of the cap body 5.
It is composed of The cap body 5 is made of metal such as aluminum, and the removable protective lid 6 is often made of synthetic resin. The cap body 5 is provided under the protective cover 6.
And a disk portion 8 having a diameter larger than that of the circular hole 7 but smaller in thickness. As is clear from FIG. 7, the disk portion 8 is sandwiched between the cap body 5 and the inner plug 4, whereby the protective lid 6 is firmly adhered to the upper surface of the cap body 5.

Conventionally, when using the medicine in the vial 2, the user has to pry his / her thumb or abdomen into the small gap S between the outer periphery of the cap body 5 and the outer periphery of the protective lid 6. Then, a force in the direction of arrow A is applied to the outer peripheral portion of the protective cover 6. Then, the protective lid 6 bends in the direction of arrow A, and when further force is applied, the disk portion 8 is bent downward and comes out of the circular hole 7 of the cap body 6 to the outside. If a perforation or the like is inserted into the joint between the disk portion 8 and the protective lid 6 so that the disk portion 8 can be cut, the protective lid 6 can be removed while the disk portion 8 is coupled to the cap body 5. Thereby, the protective lid 6 can be removed, and a part of the inner plug 4 is exposed to the outside through the circular hole 6 of the cap body 5. In this way, the user can insert the injection needle into the vial 2 through the rubber inner plug 4 from the exposed portion, and inject the lyophilized solution into the target lyophilized preparation, or into the injection cylinder of the liquid for injection. Can be inhaled. Attaching such a flip-off cap to a vial consists of a stopper 4
This is to prevent contamination of the upper part of the container and to firmly fix the inner plug 4 to prevent outflow of contents.

However, as described above, since the protective cover 6 is firmly adhered to the cap body 4, a large force is required at the time of removal, and the outer peripheral portion of the protective cover 6 and the outer peripheral portion of the cap body 4 Is very small, it is very difficult to remove the protective cover 6 with a thumb or the like. Furthermore, when the vial is used continuously, a heavy load is applied to the finger, so that the finger loses power or the nail is broken, so that it can be said that it is never easy to use for the user, for example, a nurse. Did not.

[0005] In order to solve the above problem, FIG.
Cap removal tool for so-called tuberculin vial 9
Etc. were used. This removing tool 9 has a tip 10
When the protective cover 12 of the vial is removed, the protrusion 11 is inserted between the protective cover 12 and the cap body 13, and then the handle of the removing tool 9 is supported with the tip 10 as a fulcrum. The removal operation was performed by applying a force in the direction of arrow B to the part 14.

[0006]

However, the lid for the tuberculin vial is provided with a concave portion, and the projection 11 of the removing tool 9 is inserted into the concave portion to pry open. Even when this removing tool 9 is used for a flip-off cap, it is very difficult to insert the portion 11a of the protruding portion 11 between the protective lid 12 and the cap body 13 due to its shape and the like. There was no sense of stability in the lifting operation, and the difficulty involved in removing the protective cover 12 of the flip-off cap could not be overcome.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a so-called flip-off cap for a vial, in particular, a protective lid for the cap with a simple structure and without burdening the user. It is an object of the present invention to provide a removal tool that can be removed.

[0008]

To achieve the above object, according to an aspect of the present invention is a protective cover for a flip-off cap key
Cap a remover for removing from the body, fewer
Both the removing tool body having a rectangular flat plate portion on the tip end side , and rising from the flat plate portion of the removing tool body , and in the width direction of the flat plate portion.
A rectangular plate-shaped support part having a lateral width, a tip at a short distance from the diameter of the protective cap with respect to fulcrum portions toward along
And the removal tool book so as to be substantially parallel to the flat plate portion.
And a flat tongue-shaped part provided integrally with the body .

[0009]

In the above construction, when removing the protective lid of the flip-off cap, insert the tongue into the gap between the protective lid and the cap body while suppressing a part of the protective lid by the fulcrum, Next, the removal tool main body is rotated upward with the fulcrum portion as a fulcrum. By this series of operations, the protective lid is easily removed from the cap body.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 3, a fulcrum 23 is provided downward from the distal end of a rectangular plate-shaped removal tool main body 22. The fulcrum 23 is rectangular as illustrated in FIG.
It has a shape of a plate, and has a lateral width along the width direction of the removal tool main body 22 . The width of the protective cover 6 (see FIG.
It is desirable that it be large enough to hold down (see). In order to increase the strength and safety, and to obtain a preferable contact state with the protective lid 6, the fulcrum 23
The guide portion 24 may be extended from the tip of the member toward the removal tool body 22. The removal tool main body 22 has at least a distal end portion.
The side is a rectangular plate shape, and its base side is shown, for example, in FIG.
As described above, it is possible to form various convenient shapes such as a substantially columnar shape .

A tongue 25 is provided at a predetermined distance from the fulcrum 23 on the remover body 22 via a support 26. The support portion 26 is protruded downward from the removal tool main body 22,
The tongue 25 is substantially horizontal from the tip of the support 26, that is,
It extends substantially parallel to the removal tool main body 22. Also,
The tip of the tongue-shaped portion 25 is formed in an arc shape when viewed from the up-down direction and in a tapered shape when viewed from the horizontal direction to facilitate insertion. When the material of the removal tool main body 22 is a metal plate, the tongue-shaped portion 25 and the support portion 26 are cut integrally except for the base end portion of the support portion 26, and then pressed integrally. Can be formed.

The removal tool main body 22 and the tongue 25 are connected to each other.
The distance e is sufficiently larger than the thickness e ₂ of the protective lid 6 (FIG. 7) , and the distance f between the fulcrum 23 and the tongue 25 is set smaller than the diameter d of the protective lid 6 (FIG. 7). Thereby, the removal tool 21 can be easily used.

When the removing tool body 22 is plate-shaped, both longitudinal edges 27, 27 are bent upward or downward, and ribs 28, 28 are formed along these edges 27, 27. Is formed, the removal tool main body 22 can be strengthened.
Further, a common rib 29 may be formed at the center in the longitudinal direction in order to strengthen the tongue 25 and the support 26 in the same manner.

Next, the operation of the embodiment constructed as described above will be described with reference to FIGS. First, the tip portion of the fulcrum portion 23 contacts the protective cover 6. And tongue
The tip of 25 is brought into contact with the portion between the cap body 5 and the protective lid 6. Next, when the removal tool main body 22 is slightly raised slightly upward with the fulcrum part 23 as a fulcrum, the tip of the tongue-shaped part 25 moves upward along the vertical portion 5a of the cap main body 5, and the cap main body 5 and the protective cover 4 is smoothly inserted into the gap S between the first and second (see FIG. 4).
reference). This is due to the fact that the shoulder 5b of the cap body 5 is largely curved and the angle of entry of the tip of the tongue 25 is well adapted to this curve. Further, when a force is applied upward while moving the removing tool body 22 forward, the tongue-shaped portion 25
Of the protective cover 6 is inserted into the depth of the gap S,
The protective cover 6 is easily bent upward as shown in FIG.

In the removal operation, first, the fulcrum 23
After the tip of the tongue 25 is brought into contact with the protective lid 6, the tip of the tongue 25 is inserted into the gap S. Conversely, the tip of the tongue 25 first extends along the vertical portion of the cap body 5. Even if the fulcrum portion 23 comes into contact with the protective cover 6 after being moved upward by a small amount and inserted into the gap S, the entire protective cover 6 can be easily removed from the cap body 5 as in the above-described removal operation. . In any case, the tongue 25 does not come down more than when the tip of the fulcrum 23 comes into contact with the upper surface of the protective lid 6, and therefore, it is easy to insert the tongue 25 into the gap S.

In the above embodiment, the tip of the tongue portion 25 is formed in an arc shape. However, the curvature of this arc can be set as appropriate. For example, a shape in which the center of the tip is straight and both end portions are rounded may be used. Good. Also, as shown in FIG.
25 may be cut into an arc in the opposite direction. At this time, the tip of the tongue portion 25 is easily inserted into the gap S,
Preferably, the curvature of the arc is set substantially equal to the curvature of the protective lid of the cap of the target vial.

In the above embodiment, the fulcrum 23 is provided at the tip of the remover body 22. However, if the distance between the fulcrum 23 and the tongue 25 can be appropriately set, the fulcrum 23 need not be provided at the tip. Good. Further, in the above embodiment, the guide portion 24 is extended at the tip of the fulcrum portion 23, but may be omitted. Further, in the above-described embodiment, the material of the removal tool main body 22 is metal, but any material having a predetermined strength may be used. Needless to say, a synthetic resin may be used.

[0018]

[Effect of the Invention] As is apparent from the above description , the erecting tool rises from the flat plate portion of the body and extends along the width direction of the flat plate portion.
A fulcrum in the shape of a rectangular plate having a lateral width , and the tip of the fulcrum being directed at an interval smaller than the diameter of the protective lid with respect to this fulcrum .
One side of the removal tool body so as to be
Since the removal tool is composed of the flat tongue provided on the body , the fulcrum can firmly and stably press the protective lid, and the tongue is inserted into the gap between the protective lid and the cap body. Therefore, the protective lid can be easily removed from the cap body. Therefore, the work of removing the protective lid of the vial flip-off cap can be performed easily and efficiently, and the burden on the user is greatly reduced even if the user performs the work continuously. it can. In addition, since the structure of the removing tool is simple, the number of production steps may be small and the production cost is low.
