Abstract
Abstract A convenience spray-dispenser packet including two flexible sheets of plastic or foil or the like sealed around the peripheries thereof to make an enclosure. The packet is partially filled with a liquid such as perfume or toilet water, and resilient means is provided for holding the faces of the packet a slight distance apart. First and second conduits are formed within the packet, the conduits converging on one corner of the packet. In use, the packet is disposed so that the corner is upright and a portion of the corner is cut or torn off to provide a small opening in the enclosure. Squeezing the packet effects a forcing of liquid through the first conduit and a forcing of air through the second conduit to thereby affect dispersion or spray of the liquid through the opening formed in the packet.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
156 words
A convenience packet of relatively small weight and volume for dispensing a fluid in spray-form, comprising two oppositely disposed flexible walls, said walls being sealed together at the peripheral edges thereof, resilient means for normally holding said walls apart, and a branched tube within said packet, said branched tube consisting of a main stem having two ends, one of said ends being proximate one edge of said packet defining a corner and the other of said ends being within the body of said packet, and at least one side-tube joining said main stem at an angle and proximate said one end, said corner being adapted for easy removal to expose said one end, the lengths of said main stem and said branched tube being such that said other end of said main stem is immersed in such fluid as may be within said packet and said side-tube is above said fluid when said corner is uppermost.
Claim 2
Dependent Claim
156 words
A convenience packet of relatively small weight and volume for dispensing a fluid in spray-form, comprising two oppositely disposed flexible walls, said walls being sealed together at the peripheral edges thereof, resilient means for normally holding said walls apart, and a branched tube within said packet, said branched tube consisting of a main stem having two ends, one of said ends being proximate one edge of said packet defining a corner and the other of said ends being within the body of said packet, and at least one side-tube joining said main stem at an angle and proximate said one end, said corner being adapted for easy removal to expose said one end, the lengths of said main stem and said branched tube being such that said other end of said main stem is immersed in such fluid as may be within said packet and said side-tube is above said fluid when said corner is uppermost.
Claim 3
Dependent Claim
32 words
A convenience packet as defined in claim 1, wherein said walls are of heat-sealable plastic so joined as to seal said peripheries together and form said main stem and said branch tube.
Claim 4
Dependent Claim
60 words
A convenience packet as defined in claim 1, wherein said walls are of a resilient plastic and so shaped that said walls at regions thereof exclusive of said peripheries and said tubes are normally spaced apart, said plastic walls being flexible for movement toward each other by finger pressure and being resilient for return movement upon release of finger pressure.
Claim 5
Dependent Claim
32 words
A convenience packet as defined in claim 1, wherein said resilient means comprise a flexible, readily compressible insert of a material inert to the fluid which said packet is intended to contain.
Claim 6
Dependent Claim
35 words
A convenience packet as defined in claim 1, wherein said insert is disposed in said packet at a position diagonally opposite said corner and said other end of said main stem is proximate said insert.
Claim 7
Dependent Claim
23 words
A convenience packet as defined in claim 1, wherein said corner is weakened at a tear-line to facilitate manual removal of said corner.
Claim 8
Dependent Claim
35 words
A convenience packet as defined in claim 1, wherein said walls are sufficiently flexible so that they can be folded over proximate said corner thereby providing for resealing said packet after removal of said corner.
Claim 9
Dependent Claim
119 words
A disposable dispenser packet comprising a pair of spaced walls sealed together at the edges thereof to form an enclosed chamber, means defining a dispensing passage adjacent one of said edges for communication between the exterior of said packet and said chamber when a section of said sealed walls is removed, a quantity of fluid partially filling said chamber, a first conduit within said chamber in communication with said dispensing passage and extending into said fluid when said packet is oriented to place said dispensing passage above the level of fluid in said chamber and a second conduit within said chamber in communication with said dispensing passage and extending above said fluid when said packet is oriented as aforesaid.
Claim 10
Dependent Claim
119 words
A disposable dispenser packet comprising a pair of spaced walls sealed together at the edges thereof to form an enclosed chamber, means defining a dispensing passage adjacent one of said edges for communication between the exterior of said packet and said chamber when a section of said sealed walls is removed, a quantity of fluid partially filling said chamber, a first conduit within said chamber in communication with said dispensing passage and extending into said fluid when said packet is oriented to place said dispensing passage above the level of fluid in said chamber and a second conduit within said chamber in communication with said dispensing passage and extending above said fluid when said packet is oriented as aforesaid.
Claim 11
Dependent Claim
74 words
A disposable dispenser packet as claimed in claim 8 and including resilient separator means disposed in said packet for separating said walls whereby depression of said separator means effects a supply of said fluid contained in said chamber to said dispensing passage through said first conduit and a supply of air to said dispensing passage through said second conduit to thereby effect an atomization of said fluid at the exterior of said dispensing passage.
Claim 12
Dependent Claim
32 words
A disposable dispenser packet as claimed in claim 9, wherein said resilient separator means is comprised of a flexible, readily compressible, insert of material inert to the fluid contained in said package.
Claim 13
Dependent Claim
28 words
A disposable dispenser packet as claimed in claim 8, wherein said enclosed chamber is formed with at least one weakened section, the removal thereof defining said dispensing passage.
Claim 14
Dependent Claim
20 words
A disposable dispenser packet as claimed in claim 11, wherein said at least one section is weakened at a tear-line.
Claim 15
Dependent Claim
48 words
A disposable dispenser packet as claimed in claim 12, wherein said weakened section is at a corner of said packet and said walls are sufficiently flexible so they can be folded over proximate said corner to thereby provide for resealing of said packet after removal of said corner.
Claim 16
Dependent Claim
23 words
A disposable dispenser packet as claimed in claim 9, wherein said first conduit is formed of a longer length than said second conduit.
Claim 17
Dependent Claim
29 words
A disposable dispenser packet as claimed in claim 14, wherein said first and second conduits are defined by molding the walls which form the sealed enclosure into branched tubes.
Claim 18
Dependent Claim

A disposable dispenser packet as claimed in claim 14, wherein said first and second conduits are defined by a branched tube inserted within said package, said branched tube insert including a main stem corresponding to said first conduit, and at least one side tube corresponding to said second conduit, said branched tube being shaped so that one end converges upon said main stem at said dispensing passage.
Claim 19
Dependent Claim
47 words
A disposable dispenser packet as claimed in claim 14, wherein said conduits are defined by a further seal of said two walls at a position partly contiguous to an edge to form said first conduit therebetween, a non-contiguous part of said further seal defining said second conduit.
Claim 20
