Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an infusion identification cap made of synthetic resin used for medical purposes, which can be colored for identification.

[Prior Art] Various types of infusion caps made of synthetic resin have been provided (Japanese Patent Application Laid-open No. 143678/1978, etc.), but in order to give the cap an identification function, pigments etc. are directly mixed into the synthetic resin material. There are no colored infusion caps, and conventional identification means are simply pasted labels.

[Problem to be solved by the invention] This is because the mixing of pigments is not desirable for caps for infusions, and the pigments mixed into the resin may affect the liquid inside the bottle.

[Means for Solving the Problems] Therefore, in order to solve the above problems, this invention consists of a cap divided into an upper lid body for identification that is colored by mixing a pigment, and a lower lid body that is not colored. A flange portion that is independently joined to the upper end of the bottle is formed on the lower lid, so that both the upper and lower lids are integrally molded. In addition, this device has a rubber plug installed between the upper lid body and the lower lid body, and an independent molding is placed on the lower surface of the rubber plug on the upper opening edge of the lower lid body. At the same time, we also adopted a structure that holds the body sealing film.

Further, if necessary, a tear piece can be provided in the top lid to form a tear-off opening along the cut-out portion.

[Function] The cap is separated from the upper and lower lids, and only the lower lid has a flange that connects to the bottle independently, so even if the resin of the upper lid is colored with pigment, the bottle remains intact. Contact with the liquid inside can be blocked, and it can be used as a colored cap for infusions without attaching a label or the like. In addition, since the sealing film, which is an independent molded body placed on the bottom surface of the rubber stopper, is held on the upper opening edge of the lower lid, it is suitable for use without being restricted by the upper and lower lids. You can choose from a variety of materials and ultra-thin thicknesses to prevent coring during needle stick.

[Example] The drawing is a sectional view showing an example of an infusion cap made of synthetic resin according to this invention, and 1 is an upper lid for identification made of a synthetic resin mixed with a pigment, and 2 is an upper end of the bottle. The lower lid body is formed with a flange portion 3 that is independently joined to the lower lid body. As shown in the figure, the lower lid 2 is joined to the upper lid 1 on the flange portion 3,
The structure is such that the upper lid 1 mixed with pigment does not come into contact with the liquid inside the bottle. Further, a rubber stopper 4 is provided inside, and a sealing film 6, which is an independent molded body and is arranged on the lower surface of the rubber stopper 4, is held on the upper opening edge 5 of the lower lid body 2. There is. 7
1 is an upper lid constituting the upper wall of the upper lid 1, with a cutout 8 carved on the back side and a tear-off piece 9 on the outside.
It has a so-called pull-top structure.

Therefore, when such a cap is used by joining it on a bottle, the upper lid body 1 containing the pigment is
The bottle does not come into contact with the liquid inside the bottle, and the liquid can be appropriately identified according to the color of the pigment mixed in, which is good in terms of hygiene and management.

To insert the infusion needle into the bottle, pull the tear-off piece 9 and remove the top cover 7 along the cutout 8 to open the upper lid 1, and insert the infusion needle into the exposed rubber stopper 4. What is necessary is to penetrate the sealing film 6 and insert it into the bottle. In this case, since the sealing film 6 is an independent molded body that can be made thin, there is no coring and no cracking occurs.

However, this invention is not limited to the above embodiment. For example, in the same embodiment, the upper lid 1 is joined to the lower lid 2 by abutting the lower end surface of the side wall of the upper lid 1 onto the flange 3 of the lower lid 2. Not limited.

Further, although this embodiment employs a pull-top structure, there is no problem even if the pull-top structure is not employed. In addition, even if the cutout portion 8 is formed by cutting, for example, polypropylene is used as the material for the tear-off piece 9 side, and polyethylene is used as the material for the upper lid body 1, for example, materials with different peel strengths are used. It is also possible to combine two synthetic resins and mold them into one piece so that they can be torn apart during use depending on the difference in peel strength.

[Effects of the invention] As described above, this invention is preferable in terms of safety and hygiene because it has a structure that blocks contact with the bottle and has an identification function on the upper lid, and it is convenient to use because it can be identified. Since the sealing film is composed of an independent molded body, coring, cracking, etc. can be prevented and needle puncture can be performed well.
