An improved medicinal apparatus for containing a fluid supply comprising: a vial having a body providing a primary mixing chamber and an elongate neck integral with the body and providing a cylindrical internal passage and an opening at an end of the neck; first means providing a sealed holding chamber at least partially within the vial neck, said first means having spaced walls and sealingly engageable within the vial neck; and second means for securing the first means with the vial neck, whereby a cannula on a syringe is extendible through said spaced walls to establish communication with the primary mixing chamber and whereby said holding chamber substantially confines fluid aspirating from the primary mixing chamber and from said syringe upon partial withdrawal of the cannula from the vial to prevent exposure by the user to the fluid.

Claim 12

Dependent Claim 138 words

An improved medicinal apparatus for containing a fluid supply comprising: a vial having a body providing a primary mixing chamber and an elongate neck integral with the body and providing a cylindrical internal passage and an opening at an end of the neck; first means providing a sealed holding chamber at least partially within the vial neck, said first means having spaced walls and sealingly engageable within the vial neck; and second means for securing the first means with the vial neck, whereby a cannula on a syringe is extendible through said spaced walls to establish communication with the primary mixing chamber and whereby said holding chamber substantially confines fluid aspirating from the primary mixing chamber and from said syringe upon partial withdrawal of the cannula from the vial to prevent exposure by the user to the fluid.

Claim 13

Dependent Claim 53 words

The improved medicinal apparatus of claim 10 wherein said first means comprises a disk-shaped element having a cross section conforming to the internal passage and defining one of the spaced walls and a separate stopper seals the opening at the end of the vial neck and defines the other of said spaced walls.

Claim 14

Dependent Claim 54 words

The improved medicinal apparatus of claim 10 wherein said first means comprise an enclosed cylindrical member, an enlarged head on the first means abuts the vial neck and said second means comprises a cap deformed about the enlarged head and vial neck to captively maintain the first means in fixed relationship to the vial.

Claim 15

Dependent Claim 56 words

The improved medicinal apparatus of claim 10 wherein said first means comprises a cylindrical member with peripheral surface and an enlarged rim which bears against said neck with the first means in place in the vial and said peripheral surface is interrupted to give flexibility to assist in assembling the cylindrical member in the vial neck.

Claim 16

Dependent Claim 72 words

The improved medicinal apparatus of claim 10 wherein said first means comprises a cylindrically shaped member conforming to the internal passage with a closed end defining one of the spaced walls and an open end, said first means having an enlarged rim adjacent the open end, said first means further comprising a stopper fit sealingly in the open end of the cylindrically shaped member and defining the other of the spaced walls.

Claim 17

Dependent Claim 41 words

The improved medicinal apparatus of claim 11 wherein said disk-shaped element has a peripheral surface and said second means comprises an annular rib extending radially into the internal passage and a cooperating groove on the peripheral surface of the disk-shaped element.

Claim 18

Dependent Claim 20 words

The improved medicinal apparatus of claim 14 wherein the stopper has an integrally formed luer seal for accepting a syringe.

Claim 19

Dependent Claim 140 words

In combination: a medicinal vial of the type having a mixing chamber, a neck and an opening in the neck; and an insert with a housing having a cup-shaped configuration with a closed end insertable through the opening in the vial neck, an enlarged rim on the housing to abut the head of the vial and arrest insertion of the housing in the vial at a predetermined position, and means for sealing at the end opposite the closed end to provide a sealed holding chamber, said closed end and said sealing means being penetrable by a syringe cannula to establish fluid communication with the mixing chamber, and upon removing said cannula from the insert aspirating fluid from the mixing chamber and from the syringe is substantially confined in the holding chamber to prevent exposure by the user to the fluid.

Claim 20

Dependent Claim 140 words

In combination: a medicinal vial of the type having a mixing chamber, a neck and an opening in the neck; and an insert with a housing having a cup-shaped configuration with a closed end insertable through the opening in the vial neck, an enlarged rim on the housing to abut the head of the vial and arrest insertion of the housing in the vial at a predetermined position, and means for sealing at the end opposite the closed end to provide a sealed holding chamber, said closed end and said sealing means being penetrable by a syringe cannula to establish fluid communication with the mixing chamber, and upon removing said cannula from the insert aspirating fluid from the mixing chamber and from the syringe is substantially confined in the holding chamber to prevent exposure by the user to the fluid.

Claim 21

Dependent Claim 47 words
