Enteral feeding container

Claim 2

An enteral feeding container, which comprises a container body defined by a pair of opposed, flexible, collapsible container walls, an outlet in the bottom of said container, said outlet communicating with flexible tubing which terminates at its outer end with connector means for communication with an enteral feeding catheter, and an inlet port and closure at the top of said container having a diameter of at least 2 cm., said inlet port and closure comprising a funnel member sealed to said container walls and communicating therethrough, and a closure member attached to said funnel member by integral hinge means, said funnel member defining an outwardly projecting cylindrical port, said closure member defining outer and inner annular walls spaced apart to define an annular recess proportioned to sealingly receive said outwardly projecting cylindrical port when said closure is sealing the inlet port, said inlet port and closure carrying at least one annular sealing projection for sealing between said cylindrical port and annular walls when the inlet port and closure is in closed relation.

Claim 3

The container of claim 1 in which an annular sealing projection, 0.008 to 0.025 cm. high, is positioned on the inner surface of said cylindrical port.

Claim 4

The container of claim 2 in which an annular sealing projection, 0.008 to 0.025 cm. high, is positioned on the inner surface of said outer annular wall.

Claim 5

The container of claim 1 in which said flexible container walls are made of polyvinyl chloride plastic, and said inlet port and closure comprises a single molded piece of a flexible block copolymer of covalently-bonded polybutylene terephthalate units and poly(1,4-butylene) oxide units.

Claim 6

The container of claim 4 in which 50 to 70 percent by weight of said block copolymer comprises 1,4-butylene oxide units.

Claim 7

The container of claim 1 in which one of said funnel member and closure member defines a peripherally positioned flexible, perforated lock tab, and the other of said funnel member and closure member defines an outwardly extending projection positioned and proportioned to fit through the perforated lock tab for locking the closure member in closed relation.

Claim 8

The container of claim 1 in which said inlet port and closure is a single molded piece of plastic, including integral, flexible hanger means.

Claim 9

The container of claim 1 in which said container tapers to relatively narrow bottom, whereby the filled, tapered container portion is conical in shape.

Claim 10

The container of claim 1 in which an inner surface of at least one of said container walls is roughened to reduce container wall adhesion.

Claim 11

An enteral feeding container which comprises a container body defined by a pair of opposed, flexible, collapsible container walls, an outlet in the bottom of said container, said outlet communicating with flexible tubing which terminates at its outer end with connector means for communication with an enteral feeding catheter, and an inlet port and closure at the top of said container, said port having a diameter of at least 2 cm., said inlet port and closure comprising a funnel member sealed to said container walls and communicating therethrough, and a closure member attached to said funnel member by integral hinge means, said funnel member defining an outwardly projecting cylindrical port, said closure member defining outer and inner annular walls spaced apart to define an annular recess proportioned to sealingly receive said outwardly projecting cylindrical port when said closure is sealing the inlet port, said inlet port and closure carrying annular sealing projections to seal the space between both sides of said cylindrical port and the respective annular walls when the inlet port and closure are in closed position, said flexible container walls being made of a polyvinyl chloride plastic, and said inlet port and closure being a single molded piece of a flexible block copolymer of covalently-bonded polybutylene terephthalate units and poly(1,4-butylene) oxide units.

Claim 12

An enteral feeding container which comprises a container body defined by a pair of opposed, flexible, collapsible container walls, an outlet in the bottom of said container, said outlet communicating with flexible tubing which terminates at its outer end with connector means for communication with an enteral feeding catheter, and an inlet port and closure at the top of said container, said port having a diameter of at least 2 cm., said inlet port and closure comprising a funnel member sealed to said container walls and communicating therethrough, and a closure member attached to said funnel member by integral hinge means, said funnel member defining an outwardly projecting cylindrical port, said closure member defining outer and inner annular walls spaced apart to define an annular recess proportioned to sealingly receive said outwardly projecting cylindrical port when said closure is sealing the inlet port, said inlet port and closure carrying annular sealing projections to seal the space between both sides of said cylindrical port and the respective annular walls when the inlet port and closure are in closed position, said flexible container walls being made of a polyvinyl chloride plastic, and said inlet port and closure being a single molded piece of a flexible block copolymer of covalently-bonded polybutylene terephthalate units and poly(1,4-butylene) oxide units.

Claim 13

The container of claim 10 in which the annular sealing projections on both sides of the cylindrical port are from 0.008 to 0.025 cm. high.

Claim 14

The container of claim 11 in which 50 to 70 percent by weight of said block copolymer comprises 1,4-butylene oxide units.

Claim 15

The container of claim 12 in which one of said funnel member and closure member defines a peripherally positioned, flexible, perforated lock tab, and the other of said funnel member and closure member defines an outwardly extending projection positioned and proportioned to fit through the perforated lock tab for locking the closure member in closed relation.

Claim 16

The container of claim 13 in which said inlet port and closure also includes integral flexible hanger means.

Claim 17

The container of claim 14 in which said container tapers to a relatively narrow bottom, whereby the filled, tapered container portion is conical in shape.

Claim 18

The container of claim 15 in which an inner surface of at least one of said container walls is roughened to reduce the container wall adhesion.
