## Abstract

A drug vessel includes a vessel body with a narrow neck extending to an open end of a mouth portion thereof, and a stopper fitted in the open end. The stopper includes a stopper body of an elastomeric material with a through-hole passing through a central portion thereof along its center axis, and a closing body fitted into the through-hole of stopper body to block the through-hole.

## Claims

### Claim 1

An intravenous drip infusion set comprising:
a drug vessel containing a drug and being composed of a vessel body having a mouth at one end thereof, a stopper of an elastomeric material fitted in said mouth, said stopper comprising a stopper body having a through-hole passing therethrough, and a spherical closing body press-fitted in said through-hole, said vessel body being provided in a lower portion of its outer wall with a pair of recesses and including a hanger attached to said pair of recesses, said stopper having a bottom surface with a semispherical recess coaxial with said through-hole; and
a fluid administration set separated from said drug vessel but adapted to be combined therewith just before use, said fluid administration set comprising a drip chamber having, at one end thereof, a flexible tube connected thereto and, at the ether end, a tubular connecting member adapted to be forced into said through-hole of said stopper to push the closing body into the vessel body just before use.

### Claim 2 (depends on 1)

The intravenous drip infusion set according to claim 1, wherein said stopper has a cylindrical plug portion and a flange integrated therewith, said plug portion having the through-hole and a diameter slightly greater than an inside diameter of said open end of the vessel body.

### Claim 3 (depends on 1)

The intravenous drip infusion set according to claim 1, wherein said drip chamber is provided at its upper end with a tapered tubular member with an air filter.

### Claim 4 (depends on 3)

The intravenous drip infusion set according to claim 3, wherein said flexible tube includes a clamp, an air trap and a venous needle.

### Claim 5 (depends on 1)

The intravenous drip infusion set according to claim 1, wherein said drug vessel includes a retaining chamber for retaining the closing body when said closing body is forced out of the through-hole.

### Claim 6 (depends on 5)

The intravenous drip infusion set according to claim 5, wherein a cap member is provided over said stopper with a tearable portion to provide access to the through-hole.

### Claim 7 (depends on 5)

The intravenous drip infusion set according to claim 5, wherein said recess is provided with a plurality of ribs radially extending along a semispherical surface of the recess at certain intervals.

### Claim 8 (depends on 7)

The intravenous drip infusion set according to claim 7, wherein said stopper body is provided with an annular groove at a bottom portion thereof and wherein said retaining means is defined by a retaining member fitted in said annular groove.

### Claim 9 (depends on 7)

The intravenous drip infusion set according to claim 7, wherein said stopper body is provided with a retaining chamber connected to the lower end of the through-hole and communicated with the interior of the vessel body through several holes provided in the bottom of the retaining means.

### Claim 10

A drug vessel having a stopper fitted in an open end thereof, said stopper comprising:
a stopper body of an elastomeric material with a longitudinal through-hole formed therein;
a closing body removably fitted in said through-hole for selectively blocking said through-hole; and
a retaining chamber integrally formed with said stopper body for receiving said closing body upon dislodgement thereof from said through-hole, said retaining chamber including a plurality of fluid apertures formed therein such that receipt of said closing body will not block fluid flow to said through-hole.
