Closure for containers containing an injection material

The present invention relates to a closure for a A container containing an injection material, d. H. a container such as a bottle or a deformable bag, its closure in combination on the one hand firstly a tight stopper made of a deformable material, For example, a plastic or the like includes, which from a nndel to Kntnfihino rl ρ π good, through ι rc1 cn wonlen can, and which on the other hand has means for locking the stopper in the neck of the container.

The goods stored in such a container are intended to be injected into the human body, be it by injection with a syringe, be it with the help of a needle with which a transfusion tube is equipped is.

The means for locking the closure plug made of deformable Material currently consist of a capsule made of aluminum or the like, the center of which is recessed or by a tear-off Cover sheet is closed and the lateral envelope wall is intended to be folded onto the body of the container having a shoulder for this purpose. Of the

The disadvantage of using these capsules is that their pulling, folding or crimping over a relative high the aluminum sheet from which it was cut must be coated with a varnish or grease got to. It follows from this that the crimping of the capsule is inevitable with the accumulation of impurities, in particular Paint or grease, and possibly also aluminum itself, is connected. One therefore wants in the necessary way ensure that the grout in the containers remains completely free of this contamination, it is necessary to the crimping at a distance from the filling and plugging of the containers, d. H. on another machine, make, which, however, on the other hand, the closing of the container is considerably more complicated.

The present invention is therefore based on the object

to create a closure of the generic type without

any such risk of contamination for the injection material can be attached.

The solution according to the invention is that the means for The closure plug is defined and retained in the neck of the container by a ring of semi-rigid material such as a plastic that can be cast in a mold or can be processed by injection molding, the under the neck the container provided shoulder can be clipped.

According to a preferred embodiment, the ring has a lateral cylindrical envelope wall, the lower edge of which is at least has an inwardly facing protrusion such as an annular bead that snaps under the

called shoulder on the neck of the container.

For a particularly good protection of the inject-ionuyutes im Container and to avoid the accumulation of dust on the stopper is preferred according to another Embodiment of the invention provided to close the central opening in the ring by a tear-off cover, which is attached to the ring by gluing, sealing or potting or in any other way.

An embodiment of a closure according to the invention is illustrated below with reference to the accompanying drawing.

The drawing shows an axial section through the closure and the end of the container containing the injection material.

The neck 2 of the container, which can be a bottle or a deformable bag, as used as a transfusion bag find, has such a bead 2a, the adjacent the end of the neck 2, a retaining shoulder 2b forms.

The closure initially includes a known closure plug 3 made of deformable elastic material, such as rubber or a plastic with rubber-like Properties. The stopper has a cylindrical portion 3a, which into the neck opening of the Neck 2 can be used. The sealing plug also has a collar 3b which rests on the edge of the neck 2 of the container. The safe locking and restraint

the plug 3 is guaranteed by a ring 4, which consists of a semi-rigid material that can be cast in a mold or processed by injection molding, and preferably made of a plastic such as polyethylene or polypropylene. This ring 4 is intended to the To overlap collar 3b of the plug 3 and it has a lateral cylindrical envelope wall 4a, which the bead 2a can overlap at the free end of the neck 2 of the container. A central opening 4b of the ring allows passage a needle with which the injectable material in the container can be removed.

At its lower end, the cylindrical envelope wall 4a of the ring 4 has an inwardly directed annular bead 4c, the at the end of the placement of the ring 4 on the neck 2 and the plug 3 snapping under the shoulder 2b of the Neck 2 clipped and thus the ring 4 and consequently the stopper 3 in the closed position on the container locked.

Attaching the ring 4 after placing the closure plug 3 is thus done by a simple axial pressing, without in any way the risk of Accumulation of impurities would be given. The locking of the ring 4 on the neck 2 will also end automatically achieved without the need to carry out any hemming or flanging work afterwards.

The closure according to the invention thus has the advantage that it can be put on particularly easily and with his Use a pollution attack is not given. Of the

Ring can do this on the same machine without any problem be placed on which the injection material is also filled and the stopper is put on.

If one wishes as a special extra precaution, to keep the outer surface of the plug 3 permanently free of dust accumulations and the like caused by the Central opening 4b of the ring would be possible, this is provided according to a particular embodiment of the invention Opening through a tear-off cover 5, which is attached to the ring by thermal bonding or thermal welding can be locked.

It goes without saying, and it follows from the foregoing, that the invention is not limited to the embodiment of the closure described above. As part of the Rather, numerous design variants are possible in accordance with the concept of the invention.
