Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A pourer plug device for a receptacle having a neck equipped with a sealed lid, and comprising: a plug element including means for securing said plug element to the receptacle over the sealed lid; a cylindrical core disposed at a center of said plug element; cutting means on an inner end of said core, for cutting the sealed lid; flexible means for mounting said core on said plug element securing means, for movement from an initial position toward the sealed lid so that said cutting means moves from an initial position into a cutting position in which said cutting means cuts the sealed lid; and a cap mounted for movement on said plug element, said cap being movable toward the receptacle from an initial position, to move said core and said cutting means to the cutting position, and said cap including a pouring aperture which is closed by an outer end of said core when said cap and said core are in their initial position, and which is opened when said cap is moved back to its initial position relative to said core after a sealed lid-cutting operation.
Claim 2
Dependent Claim
188 words
A pourer plug device for a receptacle having a neck equipped with a sealed lid, and comprising: a plug element including means for securing said plug element to the receptacle over the sealed lid; a cylindrical core disposed at a center of said plug element; cutting means on an inner end of said core, for cutting the sealed lid; flexible means for mounting said core on said plug element securing means, for movement from an initial position toward the sealed lid so that said cutting means moves from an initial position into a cutting position in which said cutting means cuts the sealed lid; and a cap mounted for movement on said plug element, said cap being movable toward the receptacle from an initial position, to move said core and said cutting means to the cutting position, and said cap including a pouring aperture which is closed by an outer end of said core when said cap and said core are in their initial position, and which is opened when said cap is moved back to its initial position relative to said core after a sealed lid-cutting operation.
Claim 3
Dependent Claim
91 words
The device as claimed in claim 1, wherein said flexible means is a plurality of flexible spacer strips which initially are oriented obliquely with respect to the direction of a geometrical axis of said cylindrical core, and extend away from a base of said plug element and from the sealed lid, said spacer strips bending into an oblique orientation from said base toward the sealed lid when said core is moved into the cutting position, and said spacer strips then retaining said core and said cutting means in the cutting position.
Claim 4
Dependent Claim
30 words
The device as claimed in claim 2, wherein said plug element securing means, said plug base, said spacer strips and said cylindrical core are formed integrally of the same material.
Claim 5
Dependent Claim
12 words
The device as claimed in claim 3, wherein the material is polypropylene.
Claim 6
Dependent Claim
150 words
The device as claimed in claim 2, further comprising: a cylindrical mounting portion on said base of said plug element; helically-shaped rib-and-cam-way means on said cap and said cylindrical mounting portion, for mounting said cap for rotatable and axial movement on said cylindrical mounting portion; an internal cylindrical guide portion on said cap and extending concentrically with respect to a geometrical axis of the device, for receiving and guiding a portion of said cylindrical core; a guarantee strip disposed between said plug element and said cap, to prevent movement of said cap toward the receptacle until said strip is removed; and at least one pourer opening in said cylindrical core adjacent its outer end, said pourer opening being closed by said cap when said core and said cap are in their initial positions, and being opened when said cap is moved relative to said core after the sealed lid-cutting operation.
Claim 7
Dependent Claim
46 words
The device as claimed in claim 1, further comprising: a cylindrical mounting portion on a base of said plug element; and helically-shaped rib-and-cam-way means on said cap and said cylindrical mounting portion, for mounting said cap for rotatable and axial movement on said cylindrical mounting portion.
Claim 8
Dependent Claim
37 words
The device as claimed in claim 1, wherein said cap includes an internal cylindrical guide portion extending concentrically with respect to a geometrical axis of the device, for receiving and guiding a portion of said cylindrical core.
Claim 9
Dependent Claim
23 words
The device as claimed in claim 1, wherein said sealed lid is joined to the neck of the receptacle and said plug element.
Claim 10
Dependent Claim
34 words
The device as claimed in claim 1, further comprising: a guarantee strip disposed between said plug element and said cap, to prevent movement of said cap toward the receptacle until said strip is removed.
Claim 11
Dependent Claim
58 words
The device as claimed in claim 1, wherein said cylindrical core also includes at least one pourer opening adjacent its outer end, said opening being closed by said cap when said core and said cap are in their initial positions, and being opened when said cap is moved relative to said core after the sealed lid cutting operation.
