Abstract
Abstract A pouring plug for a container having two members, namely a tubular body for mounting on a container wall and a lid mounted or threadedly mounted internally of the tubular body, a tubular blade is connected to an end of a mounting portion or threaded mounting portion of the lid by an easily rupturable connecting portion or portions, and a separating structure is provided between the tubular blade and the mounting portion or the threaded mounting portion. Rotation-stop elements for the tubular blade are provided between the outer wall of the tubular blade and the inner wall of the tubular body.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
A two piece pouring plug for a container, comprising: a hollow tubular body having a lower end for mounting on a container wall; and a lid member removably mounted on an upper end of said tubular body and having a lid mounted over the open upper end of said tubular body and said lid having a mounting portion on the under side thereof and a tubular blade connected to a lower end of said mounting portion of said lid by at least one easily rupturable connecting portion integrally formed with said tubular blade and said mounting portion, said lid member having a separating means between said tubular blade and said mounting portion, and a rotation stop means for the tubular blade on each o the outer wall of said tubular blade and the inner wall of said tubular body and engageable for stopping relative rotational movement of said tubular blade and said tubular body.
Claim 2
Dependent Claim
154 words
A two piece pouring plug for a container, comprising: a hollow tubular body having a lower end for mounting on a container wall; and a lid member removably mounted on an upper end of said tubular body and having a lid mounted over the open upper end of said tubular body and said lid having a mounting portion on the under side thereof and a tubular blade connected to a lower end of said mounting portion of said lid by at least one easily rupturable connecting portion integrally formed with said tubular blade and said mounting portion, said lid member having a separating means between said tubular blade and said mounting portion, and a rotation stop means for the tubular blade on each o the outer wall of said tubular blade and the inner wall of said tubular body and engageable for stopping relative rotational movement of said tubular blade and said tubular body.
Claim 3
Dependent Claim
148 words
A two piece pouring plug for a container, comprising: a hollow tubular body having a lower end for mounting on a container wall; and a lid member removably threadedly mounted on an upper end of said tubular body and having a lid mounted over the open upper end of said tubular body and said lid having a threaded mounting portion on the under side thereof and a tubular blade connected to a lower end of said mounting portion of said lid by at least one easily rupturable connecting portion integrally formed with said tubular blade and said mounting portion, said lid member having a separating means between said tubular blade and said mounting portion, the distance from said mounting portion of said lid to a lower end of said tubular blade being greater than the distance from the upper end to the lower end of said tubular body.
Claim 4
Dependent Claim
148 words
A two piece pouring plug for a container, comprising: a hollow tubular body having a lower end for mounting on a container wall; and a lid member removably threadedly mounted on an upper end of said tubular body and having a lid mounted over the open upper end of said tubular body and said lid having a threaded mounting portion on the under side thereof and a tubular blade connected to a lower end of said mounting portion of said lid by at least one easily rupturable connecting portion integrally formed with said tubular blade and said mounting portion, said lid member having a separating means between said tubular blade and said mounting portion, the distance from said mounting portion of said lid to a lower end of said tubular blade being greater than the distance from the upper end to the lower end of said tubular body.
Claim 5
Dependent Claim
60 words
A pouring plug as claimed in claim 1 or 2 wherein said separating means has inclined surfaces on said tubular blade and said mounting portion, said inclined surfaces being opposed to each other for causing said tubular blade to be moved toward the lower end of said tubular body when said mounting portion is rotated relative to said tubular blade.
Claim 6
Dependent Claim
79 words
A pouring plug as claimed in claim 1 or 2 wherein said separating means comprises an inclined surface on one of said tubular blade and said mounting portion and a projecting on the other of said tubular blade and said mounting portion, said inclined surface and projection being engaged with each other for causing said tubular blade to be moved toward the lower end of said tubular body when said mounting portion is rotated relative to said tubular blade.
Claim 7
Dependent Claim
27 words
A pouring plug as claimed in claim 1 in which said rotation stop means is a projection one each of said tubular body and said tubular blade.
Claim 8
Dependent Claim
41 words
A pouring plug as claimed in claim 1 in which said rotation stop means is a projection on one of said tubular body and said tubular blade and a recess in the other of said tubular body and said tubular blade.
Claim 9
Dependent Claim
28 words
A pouring lug as claimed in claim 1 in which said rotation stop means is a rough surface one each of said tubular body and said tubular blade.
Claim 10
Dependent Claim
34 words
A pouring lug as claimed in claim 1 in which said lid member and said tubular body each have thread means thereon for being engaged to mount said lid member on said tubular body.
Claim 11
Dependent Claim
37 words
A pouring plug as claimed in claim 1 in which said lid member and said tubular body each have continuous or discontinuous annular projections thereon for being engaged to mount said lid member on said tubular body.
Claim 12
Dependent Claim
51 words
A pouring plug as claimed in claim 1 in which the distance from said mounting portion of the lid to a lower end of said tubular blade which includes said easily rupturable connecting portion is less than the distance form the upper end to the lower end of said tubular body.
Claim 13
Dependent Claim
36 words
A pouring plug according to claim 1 or 2 in which said tubular blade is smaller in diameter than portion of the container wall in which an opening is to be formed by said tubular blade.
