Abstract
Abstract A peripherally sealed package (20) contains a bunched up portion (22a) of dental floss or other filament (22) with the outer ends (22b) of the floss or filament being disposed within and secured by sealed ends (26b and 26d) of the package. A notch (30) whose cut (30a and 30b) enables the package to be opened, uses a segment (34) of the package as a handle to draw the filament untangled and unknotted from the package. The package is formed using instrumentation including a feed tube (84) and a mandrel (86) which are concentrically positioned and relatively movable with respect to one another in timed movements. These movements, in conjunction with an accompanying sealer (54), holders (58, 72) and cutter (74a, 74b), draw an uncut length of filament (22) between two films (52a, 52b) of wrapping material, and bunch up a measured amount (22a) of the filament for deposit into an open-ended compartment (28) formed from the wrapping material.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
95 words
a packaging system for containing segments of a flaccid item comprising a length of tubular material, seals spaced from one another extending along the length of said tubular material and thus dividing said tubular material into a plurality of sealed compartments, and an uncut continuous length of said flaccid item extending through and within said tubular material and both sealed within said seals and contained within said sealed compartments, and tearing means disposed in the periphery of each sealed compartment for tearing across the compartment to dispense an end of the flaccid item without entanglement.
Claim 2
Dependent Claim
95 words
a packaging system for containing segments of a flaccid item comprising a length of tubular material, seals spaced from one another extending along the length of said tubular material and thus dividing said tubular material into a plurality of sealed compartments, and an uncut continuous length of said flaccid item extending through and within said tubular material and both sealed within said seals and contained within said sealed compartments, and tearing means disposed in the periphery of each sealed compartment for tearing across the compartment to dispense an end of the flaccid item without entanglement.
Claim 3
Dependent Claim
54 words
A packaging system according to claim 1 in which each of said seals extend sufficiently between adjacent ones of said compartments to enable said tubular material and said flaccid item sealed therewithin to be separated wholly within said seals and to maintain the sealed integrity of said compartment and said flaccid item contained therewithin.
Claim 4
Dependent Claim
15 words
A packaging system according to claim 2 in which said flaccid item comprises a filament.
Claim 5
Dependent Claim
14 words
A packaging system according to claim 3 in which said filament comprises dental floss.
Claim 6
Dependent Claim
27 words
A packaging system according to claim 2 in which said tubular material comprises heat sealable material, and said seals comprise locally heat-sealed portions of said tubular material.
Claim 7
Dependent Claim
36 words
A packaging system according to claim 5 in which said tubular material comprises at least one strip, and at least one sealed portion extending lengthwise of said tubular material and generally perpendicular to said spaced seals.
Claim 8
Dependent Claim
38 words
A packaging system according to claim 5 in which said tubular material comprises at least two strips, and at least two parallelly extending sealed portions extending lengthwise of said tubular material and generally perpendicular to said spaced seals.
Claim 9
Dependent Claim
41 words
A packaging system according to claim 2 in which said tubular material comprises a walled structure having inner and outer surfaces, with heat-sealable material defining said inner surface, and said seals comprise locally heat-sealed portions of said tubular material inner surface.
Claim 10
Dependent Claim
77 words
A flaccid item dispensing package comprising: a pair of peripherally sealed, superimposed sheets that define a compartment; a continuous, untangled, flaccid item having an intermediate portion terminating in opposite end portions, with the intermediate portion being disposed within said compartment and the opposite end portions being disposed within and secured by said peripheral seal at first and second positions; and tearing means for tearing across said package to dispense an end of the flaccid item without entanglement.
Claim 11
Dependent Claim
77 words
A flaccid item dispensing package comprising: a pair of peripherally sealed, superimposed sheets that define a compartment; a continuous, untangled, flaccid item having an intermediate portion terminating in opposite end portions, with the intermediate portion being disposed within said compartment and the opposite end portions being disposed within and secured by said peripheral seal at first and second positions; and tearing means for tearing across said package to dispense an end of the flaccid item without entanglement.
Claim 12
Dependent Claim
35 words
A flaccid item dispensing package according to claim 9 in which said flaccid item intermediate portion disposed within said compartment has a bunched-up length which is greater than any internal linear dimension of said compartment.
Claim 13
Dependent Claim
64 words
A flaccid item dispensing package according to claim 10 in which said tearing means is positioned substantially adjacent to one of the end portions of the flaccid item to enable the removal of a package segment incorporating said one end portion of said flaccid item whereby said package segment acts as a handle for the untangled removal of said flaccid item from said compartment.
Claim 14
Dependent Claim
39 words
A flaccid item dispensing package according to claim 11 in which said package has a rectangular configuration, and said tearing means comprises a notch extending partially into said peripheral seal, and said segment comprises a corner of said package.
Claim 15
Dependent Claim
29 words
A flaccid item dispensing package according to claim 12 in which said notch comprises a chevron cut pointing in the direction of separation of said segment from said package.
Claim 16
Dependent Claim
32 words
A flaccid item dispensing package according to claim 11 in which said sheets include interfaces of heat-sealable material and outerfaces with said interfaces being heat-sealed within the area of the peripheral seal.
Claim 17
Dependent Claim
26 words
A flaccid item dispensing package according to claim 14 in which said outerface of at least one of said sheets comprises paper, plastic or aluminum foil.
Claim 18
Dependent Claim
27 words
A flaccid item dispensing package according to claim 14 in which said flaccid item comprises a filament of natural fiber, synthetic fiber, metallic wire or combinations thereof.
Claim 19
Dependent Claim
17 words
A flaccid item dispensing package according to claim 14 in which said flaccid item comprises dental floss.
