Abstract
Abstract A slide fastener comprising a pair of stringer tapes carrying rows of discrete coupling elements along their respective longitudinal inner edges and a slider reciprocably movable along the rows of elements to open and close the fastener. A decorative coat is deposited with heat and pressure upon the coupling element and specifically extends at least partially into a rear and region of the coupling element to ensure freedom of separation of the cost from the skin of the coupling element.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
165 words
A slide fastener comprising a pair of stringer tapes, rows of discrete coupling elements secured respectively to longitudinal inner edges and of said stringer tapes and a slider reciprocably movable along said rows of coupling elements, each of said coupling elements having at one end a bulged coupling head portion, a barrel portion and a heel portion, and a decorative coat deposited over an upper surface of said coupling element and extending at least partially into a vertical rear end region of said heel portion, beyond a corner region into a vertical front end region of said coupling head portion, beyond a corner region into a vertical rear end region of said heel portion, and further partially into opposite vertical side regions of said coupling element, wherein said decorative coat is derived from a composite heat transfer film comprising a cover layer, a releasing layer, a protective layer, a depositing metal layer, and a heat sensitive adhesive layer superimposed one on another in this order.
Claim 2
Dependent Claim
165 words
A slide fastener comprising a pair of stringer tapes, rows of discrete coupling elements secured respectively to longitudinal inner edges and of said stringer tapes and a slider reciprocably movable along said rows of coupling elements, each of said coupling elements having at one end a bulged coupling head portion, a barrel portion and a heel portion, and a decorative coat deposited over an upper surface of said coupling element and extending at least partially into a vertical rear end region of said heel portion, beyond a corner region into a vertical front end region of said coupling head portion, beyond a corner region into a vertical rear end region of said heel portion, and further partially into opposite vertical side regions of said coupling element, wherein said decorative coat is derived from a composite heat transfer film comprising a cover layer, a releasing layer, a protective layer, a depositing metal layer, and a heat sensitive adhesive layer superimposed one on another in this order.
Claim 3
Dependent Claim
41 words
A slide fastener according to claim 1 wherein said decorative coat is deposited over both said upper surface and a lower surface of said coupling element and extends at least partially into said vertical rear end region of said heel portion.
