Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
142 words
A plastic article, being a container in the form of a flower pot, comprising: a first plastic portion having a series of protrusions extending therefrom and adjacent to each other, the protrusions being fins with a zigzag pattern; and a second plastic portion molded between and over the protrusions of the first plastic portion, thereby forming a projecting protuberance on the plastic article having a desired profile, at least some of the protrusions extending into locations of the protuberance that are projected from the plastic article, the protrusions extending from the first plastic portion being contoured to provide a general approximation of the desired profile of the protuberance, the first plastic portion being an inner container portion and the second plastic portion being an outer container portion molded over the inner container portion, the protuberance forming an upper rim of the container.
Claim 2
Dependent Claim
142 words
A plastic article, being a container in the form of a flower pot, comprising: a first plastic portion having a series of protrusions extending therefrom and adjacent to each other, the protrusions being fins with a zigzag pattern; and a second plastic portion molded between and over the protrusions of the first plastic portion, thereby forming a projecting protuberance on the plastic article having a desired profile, at least some of the protrusions extending into locations of the protuberance that are projected from the plastic article, the protrusions extending from the first plastic portion being contoured to provide a general approximation of the desired profile of the protuberance, the first plastic portion being an inner container portion and the second plastic portion being an outer container portion molded over the inner container portion, the protuberance forming an upper rim of the container.
Claim 3
Dependent Claim
23 words
The article of claim 1 in which the protrusions each have a height and a thickness, the height being greater than the thickness.
Claim 4
Dependent Claim
28 words
The article of claim 1 in which the inner container portion includes an inner pattern formed thereon for supporting a corresponding outer pattern on the outer container portion.
Claim 5
Dependent Claim
16 words
The article of claim 1 in which the inner container portion has a fluted side wall.
Claim 6
Dependent Claim
13 words
The article of claim 1 in which the protuberance is unitary and thickened.
Claim 7
Independent Claim
140 words
A method of forming a plastic article, being a container in the form of a flower pot, comprising: providing a first plastic portion having a series of protrusions extending therefrom and adjacent to each other, the protrusions being fins with a zigzag pattern, the first plastic portion being formed by injection molding in a first mold configuration; and injection molding a second plastic portion between and over the protrusions of the first plastic portion to form a projecting protuberance on the plastic article of a desired profile, a least some of the protrusions extending into locations of the protuberance that are projected from the plastic article, the first plastic portion being an inner container portion and the second plastic portion being an outer container portion molded over the inner container portion, the protuberance being an upper rim of the container.
Claim 8
Independent Claim
140 words
A method of forming a plastic article, being a container in the form of a flower pot, comprising: providing a first plastic portion having a series of protrusions extending therefrom and adjacent to each other, the protrusions being fins with a zigzag pattern, the first plastic portion being formed by injection molding in a first mold configuration; and injection molding a second plastic portion between and over the protrusions of the first plastic portion to form a projecting protuberance on the plastic article of a desired profile, a least some of the protrusions extending into locations of the protuberance that are projected from the plastic article, the first plastic portion being an inner container portion and the second plastic portion being an outer container portion molded over the inner container portion, the protuberance being an upper rim of the container.
Claim 9
Dependent Claim
22 words
The method of claim 6 further comprising molding the second plastic portion over the first plastic portion in a second mold configuration.
Claim 10
Dependent Claim
24 words
