ready enjoined so to prevent contamination, and wherein external manipulation thereof places them into operative condi tion. l

. Other objects are to provide a partially assembled bulk parenteral solution container and administration set which is simple in design, inexpensive to manufacture, rugged inconstruction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a side cross-sectional view of the invention.

FIG. 2 is an exploded perspective view of the invention.

FIG. 3 is a side cross-sectional view of a modified form of the invention.

Referring now tothe drawing in detail, the reference numeral represents a partially assembled bulk parenteral solution container and administration set according to the present invention, wherein there is an administrative cap 11 over the mouth 12 of a bottle 13.

The cap 11 includes plastic body 14 having internal thread 15 engaged on external thread 16 of the bottle. A rubber plug 17 having a thin central diaphragm 18 is fitted into the bottle mouth sealing the bottle interior 19. A central needle 20 integrally formed with the body 14 carries a passage 21 therethrough which communicates with a drip chamber 22 made of transparent plastic and fitted over a nipple 23 formed on the body. Another passage 24 extends through the needle 20 and is parallel topassage 21; the passage 24 communicating with an air filter unit 25 formed on the body. The unit 25 includes a check valve 26 comprised of steel ball 27 normally urged by a compression coil spring 28 against a valve seat 29 so to normally close the passage 24. A filter screen 30 is fitted over the end of the passage 24 and secured in position by a removable bezel 31. Q

The drip chamber 22 is connected to one end of a hose 32 having a manually closable clamp 33 along the length thereof for purpose of squeezing the hose so to seal the hose passage fully or in part for controlling flow volume therethrough.

The bottle 13 includes a circular flange 34 integrally formed around the neck 35 thereof. A flexible sleeve 36 has a central opening at one end fitted around the cap 11; the cap having a bead 37 which fits into a groove 38 of the sleeve. The opposite end of the sleeve has'an upward turned edge 39, which is forced down to snap around the flange 34, so that the sleeve can not be accidentally removed during operational use, thereby sealing the contents from contamination. The sleeve 36 can be made integral with the body 14.

In preoperative use, the device is initially in the position shown in FIG. 1, with edge 39 in the sealed solid linepositio'n. Upon rotation of the body relative to the bottle the threads 15 and 16 cause the body to descend, causing the needle to punc-' ture the diaphragm, and allowing the bottle contents to flow out of the passage 21 when the device is inverted. The valve 26 prevents escape of the bottle contents out of the air filter unit 25;

The air filter bezel is removable for adding medication into the cap which will be prevented from flowoutward from the air filter by the checkvalve.

In a modified construction 50 shown in FIG. 3, the cap 51 is vertically, axially slidable on the bottle instead of being rotatable as above described. In this form of the invention, the cap includes a relativel thin integral formed sleeve 52. The cap 51 and the sleeve 2 are both made of resilient material and are integrally formed together. The interior side wall of the cap includes an upper circular groove 57a and a lower circular groove 57b. The bottle includes on the outer side of the bottle neck an upper bead 55 and a lower head 56. Prior to operative use, an upturned resilient lower edge 62 of the sleeve 52 is snapped around a flange 53 integrally formed on the bottle (see dotted lines). In operative use, the cap is simply pushed axially causing the cap groove to disengage bead 55 from the groove 57b. As the cap descends, the groove 57b snaps over bead 56, while at the same-instant, the needles 60 and 61 pierce the diaphragm. The cap carries drip chamber 58 and air filter 59, each with its own needle 60 and 61 respectively. The needles pierce the plug diaphragm upon downward travel, thus allowing outward flow of the formerly sealed bottle content. The air filter 59 is provided with a valve similar to the ball valve 27 of FIG. 1 to prevent flow outward through the filter.

While various changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention.


1. In a partially assembled bulk parenteral solution container and administration set, the combination of a bottle hav ing a neck surrounding an open mouth, a movable cap mounted on the neck adjacent the mouth, a frangible plug sealingly fixed within said mouth, and a flexible sleeve secured at right angles to the cap and having a longitudinal portion extending towards the bottle beyond the mouth, said portion being securable to the bottle radially spaced from the neck, said cap having a passage extending from the mouth through the cap.

2. The combination as set forth in claim 1 wherein said cap comprises a body having an internal thread engaging an external thread on said bottle neck, a central needle integrally formed on said body a passage through said needle communicating with a drip chamber secured on a nipple formed on said body, a second passage through said needle communicating with an air filter on said body, said air filter comprising a check valve having a steel ball normally urged against a valve seat by a spring to close said second passage, said filter having a filter screen across the end of said second passage secured by a bezel, and said plug including a central thin diaphragm rupturable by said needle.

3. The combination as set forth in claim 2 wherein said bottle includes a flange around said neck, one end of said sleeve rigidly secured to said flange, the opposite end of said sleeve having a groove receiving rotationally free a bead formed around said cap body.

4. The combination as set forth in claim 1 wherein said bottle neck includes a pair of axially spaced apart beads selectively engaging a groove on said cap, said sleeve being integral at one end with said cap, the opposite end of said sleeve fixedly engaging a flange around said bottle neck a drip chamber and an air filter on said cap, said drip chamber and air filter each having a hollow needle in alinement to pierce a thin diaphragm centrally formed on said plug when said cap is axially pushed.
