Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinged cap with a needle, and more particularly, a closure membrane of a tube with a closure membrane can be opened with a needle attached to the cap, and can be used as a normal one-touch cap after opening. The present invention relates to a hinge cap with a needle.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a cap with a needle 52 is screwed into an opening 51 of a tube 50 with a closing film made of metal or synthetic resin. Then, when extracting the contents, as shown in FIG. 6, the cap 52 with the needle removed from the mouth portion 51 is inverted, and the needle body 54 formed outside the top surface portion 53 of the cap 52 with the needle is used. Pierced the closing film 55 formed in the mouth portion 51 to extract the contents. Next, after opening the mouth portion 51, it was rotated around the mouth portion 51 in the same manner as a normal cap, and the cap with needle 52 was screwed into the mouth portion 51 to close the mouth portion 51.

[0003]

However, in such an invention, after opening the mouth portion 51 of the tube with a closing membrane 50, the cap with needle 52 is re-attached to the mouth portion 51 using both hands. It has to be screwed together, and cannot be closed with one hand and one touch operation. In addition, in the case of a generally used one-touch cap that can be opened and closed with one hand, it is necessary to separately prepare an opening tool for opening the closing membrane, which is troublesome.

The present invention has been made in view of such a conventional problem. After opening the mouth with a needle attached to the one-touch cap, the mouth is opened by one-touch operation with the same cap. An object of the present invention is to provide a hinge cap with a needle that can be opened and closed.

[0005]

According to the present invention, a lid is attached to a cap body screwed to a mouth portion of a tube with a closing membrane via a hinge so as to be openable and closable. A hinge cap with a needle, wherein a needle body is formed outside the top surface portion, and a wall body is formed outside the top surface portion so as to surround the needle body.

[0006]

Next, an embodiment of the present invention will be described with reference to the drawings. In the hinge cap with a needle according to the present invention, the lid 1 and the cap body 2 are connected by a hinge portion. The hinge 3 includes a long hinge 3a reaching the upper surface of the lid 1 and short hinges 3 provided on both sides thereof.
b. The long hinge 3a has an L-shaped cross-section, which, together with the other short hinges 3b, hinges. When the lid 1 is opened as shown in FIG. 2, the short hinge 3b is bent from the boundary between the lid 1 and the cap main body 2, and the long hinge 3a is bent from the base slightly below the boundary. Can be When the lid 1 is opened, it is opened to a certain angle while being pulled by the long hinge 3a, and when it exceeds a certain angle, the long hinge 3
Due to the tension a, the lid 1 is suddenly opened further to a certain angle, and the lid 1 is kept open at that position.

On the outside of the top surface portion 4 of the cover 1, a needle 5 is projected upward. The wall 6 is formed high so as to cover the length of the needle body 5 so as to surround the needle body 5. The wall 6 serves to prevent the tip of the needle 5 from touching a finger or the like of the hand. The lid 1 on which the needle body 5 and the wall body 6 are formed as described above and the cap body 2 are connected via the hinge 3, but are usually all integrally formed. Further, the lid 1 and the cap main body 2 may be separately formed and connected by the hinge 3. The female thread 2a of the cap body 2 is screwed to the male thread 9a of the closing membrane tube 8, and the cap body 2 is fixed to the mouth 9.

Next, the operation of the present invention will be described.
As shown in FIG. 4, the cap body 2 according to the present invention is
The mouth 9 of the closure membrane tube 8 is opened by removing the needle 5 from the mouth 9 of the closure membrane tube 8 and piercing the closure membrane 7 with the tip end of the needle body 5 turned upside down. After the closing film 7 is opened, the receiving cylinder 11 of the lid 1 is fitted or disengaged from the protruding cylinder 10 in the same manner as a normal one-touch cap, so that it can be freely opened and closed with one touch.

[0009]

As described above, according to the present invention, after the closing membrane of the closing membrane tube is opened with the needle attached to the one-touch cap, the same cap is operated with one hand by one-touch operation. Opening and closing operations of the unit become possible. Also, due to the wall formed around the needle,
This has an effect of preventing a finger or the like from touching the needle body.
