Abstract
Abstract A beaded article having a support layer on which a bottom layer and a top layer of sheet material are superimposed. The top layer is heat bonded to the bottom layer and both are heat bonded to the support layer along a circumferentially complete narrow annular zone. In the area circumscribed by the annular zone the top layer is provided with a raised self-supporting bead-like prominence which contains ornamental particles visible to a viewer because the top layer is of transparent material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A method of making an ornamented article, comprising the steps of confining an intermediate layer of discrete particles between a bottom layer and a top layer having an exposed surface, the material of at least one of said top and bottom layers being thermoplastic and said top layer being plastically flowable; pressing said top layer against said bottom layer in at least one circumferentially complete narrow marginal zone; heat-bonding said top and bottom layers to one another in said circumferentially complete narrow marginal zone; and forming in said top layer a raised self-supporting bead which projects beyond the level of said surface by engaging said top layer under pressure with a die and thereby forcing said top layer to flow plastically in direction inwardly and upwardly away from said zone simultaneously with the step of heat-bonding said top and bottom layers to one another, said bead being circumscribed by the associated marginal zone and containing confined particles of said intermediate layer.
Claim 2
Independent Claim
161 words
A method of making an ornamented article, comprising the steps of confining an intermediate layer of discrete particles between a bottom layer and a top layer having an exposed surface, the material of at least one of said top and bottom layers being thermoplastic and said top layer being plastically flowable; pressing said top layer against said bottom layer in at least one circumferentially complete narrow marginal zone; heat-bonding said top and bottom layers to one another in said circumferentially complete narrow marginal zone; and forming in said top layer a raised self-supporting bead which projects beyond the level of said surface by engaging said top layer under pressure with a die and thereby forcing said top layer to flow plastically in direction inwardly and upwardly away from said zone simultaneously with the step of heat-bonding said top and bottom layers to one another, said bead being circumscribed by the associated marginal zone and containing confined particles of said intermediate layer.
Claim 3
Dependent Claim
30 words
A method as defined in claim 1, wherein said particles are ornamental particles, and wherein said top layer is transparent for permitting viewing of the confined particles in said bead.
Claim 4
Dependent Claim
37 words
A method as defined in claim 1, further comprising the step of maintaining said top layer spaced from said bottom layer by entrapping gas between said layers, and effecting expansion of said gas in said confined area.
Claim 5
Dependent Claim
23 words
A method as defined in claim 3, wherein said top layer is a thermoplastic material subject to softening under the influence of heat.
Claim 6
Dependent Claim
44 words
A method as defined in claim 4, said bead being dome-shaped, and the thickness of said top layer being so selected as to resist, in conjunction with the dome shape, collapse of said bead when said gas contracts on cooling subsequent to said expansion.
Claim 7
Dependent Claim
31 words
A method as defined in claim 1, further comprising the step of severing at least said top layer at least concomitantly with the step of heat-bonding said layers to one another.
Claim 8
Dependent Claim
16 words
A method as defined in claim 1, wherein said material of said top layer is polyvinylchloride.
Claim 9
Dependent Claim
16 words
A method as defined in claim 1, wherein said top and bottom layers are gas impermeable.
