Abstract

Abstract A dental hygiene product in the form of a packet having a front panel and a back panel containing a pre-cut length of dental floss thread stored as a coil. The packet is severable into first and second packet portions, and opposite ends of the thread are affixed to respective packet portions which, after being severed, form grip tabs to facilitate withdrawal and use of the floss thread. A perimeter slit helps start the tearing of the packet. A plurality of packets may be constructed in strip-wise and matrix array configurations, and the packets may be separable along perforations. When constructed as a packet set, a single thread may define coiled portions for respective packets, and cuts may be made to sever the thread into thread units. A layer of tacky material may be disposed on a portion of the interior surface of one of the front and back panels to initially adhere the dental floss thread in a selected configuration on the interior surface of one of the panels.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 178 words
A dental hygiene product, comprising: a substantially flat packet having a flat front panel and a flat back panel each formed of a flexible material and secured together along a common perimeter to define an enclosure having an interior, said packet being severable into first and second packet portions; a layer of tacky material disposed on a portion of an interior surface of one of said front and back panels; and a thread of dental floss stored within the interior of said packet, said thread having a first end secured to said first packet portion and a second end secured to said second packet portion so that, when said packet is severed into said first and second packet portions, the enclosure is ruptured whereby said thread may be withdrawn, said first and second packet portions defining first and second tabs, respectively, adapted to facilitate manual gripping of the first and second ends of the thread, said tacky material operative to initially adhere said thread in a selected configuration on the interior surface of the associated said one panel.
Claim 2
Dependent Claim 178 words
A dental hygiene product, comprising: a substantially flat packet having a flat front panel and a flat back panel each formed of a flexible material and secured together along a common perimeter to define an enclosure having an interior, said packet being severable into first and second packet portions; a layer of tacky material disposed on a portion of an interior surface of one of said front and back panels; and a thread of dental floss stored within the interior of said packet, said thread having a first end secured to said first packet portion and a second end secured to said second packet portion so that, when said packet is severed into said first and second packet portions, the enclosure is ruptured whereby said thread may be withdrawn, said first and second packet portions defining first and second tabs, respectively, adapted to facilitate manual gripping of the first and second ends of the thread, said tacky material operative to initially adhere said thread in a selected configuration on the interior surface of the associated said one panel.
Claim 3
Dependent Claim 46 words
A dental hygiene product according to claim 1 wherein said first and second panels are formed of tearable material, said packet having a slit means formed at a peripheral edge for initially starting a tear that severs said packet into said first and second packet portions.
Claim 4
Dependent Claim 20 words
A dental hygiene product according to claim 1 wherein said thread is stored as a coiled configuration in said interior.
Claim 5
Dependent Claim 20 words
A dental hygiene product according to claim 1 wherein said thread is stored in a zig-zag configuration in said interior.
Claim 6
Dependent Claim 20 words
A dental hygiene product according to claim 1 where said thread is stored in a helical configuration in said interior.
Claim 7
Dependent Claim 54 words
A dental hygiene product according to claim 1 wherein said front and back panels have a common geometrical configuration and are sealed by an adhesive along at least a portion of their common perimeter, said adhesive operative to secure said first and second ends of the thread to said first and second packet portions.
Claim 8
Dependent Claim 18 words
A dental hygiene product according to claim 1 wherein said thread is ten to eighteen inches in length.
Claim 9
Dependent Claim 13 words
A dental hygiene product according to claim 1 wherein said thread is flavored.
Claim 10
Dependent Claim 220 words
A dental hygiene product, comprising: a plurality of substantially flat packets connected together in edge-to-edge relation to define a strip of discrete packets, said packets each being individually and successively detachable from said strip: each said packet having complimentary front and back panels secured together around their common perimeter to define an enclosure having an interior, each said packet being formed of a flexible and tearable material whereby each packet may be severed into first and second packet portions; a thread segment of dental floss stored within the interior of each said packet, each said thread segment having a first end secured to its respective said first packet portion and a second end secured to its respective said second packet portion so that, when the said packet is severed into its respective first and second packet portions, the enclosure is ruptured whereby the respective stored thread segment maybe withdrawn, said first and second packet portions thereby defining first and second tabs adapted to facilitate manual gripping of the respective ends of the thread segment: and slit means at a selected location between each adjacent pair of connected packets, said thread segments initially being a continuous thread, said slit means for severing adjacent thread ends of adjacent packets without severing said adjacent packets from one another to form said thread segments.
Claim 11
Dependent Claim 220 words
A dental hygiene product, comprising: a plurality of substantially flat packets connected together in edge-to-edge relation to define a strip of discrete packets, said packets each being individually and successively detachable from said strip: each said packet having complimentary front and back panels secured together around their common perimeter to define an enclosure having an interior, each said packet being formed of a flexible and tearable material whereby each packet may be severed into first and second packet portions; a thread segment of dental floss stored within the interior of each said packet, each said thread segment having a first end secured to its respective said first packet portion and a second end secured to its respective said second packet portion so that, when the said packet is severed into its respective first and second packet portions, the enclosure is ruptured whereby the respective stored thread segment maybe withdrawn, said first and second packet portions thereby defining first and second tabs adapted to facilitate manual gripping of the respective ends of the thread segment: and slit means at a selected location between each adjacent pair of connected packets, said thread segments initially being a continuous thread, said slit means for severing adjacent thread ends of adjacent packets without severing said adjacent packets from one another to form said thread segments.
Claim 12
Dependent Claim 29 words
