Abstract
Abstract A disposable portion package for liquids, pastes, creams, powders or the like includes a casing (1,2) made of a flexible film adapted to enclose the packaged substance and also a certain amount of air or other gas. The package has at least one conduit (5) arranged to open by means of pressure produced inside the package, for example by pressing the package between the fingers, in order to obtain the contents for use, preferably as a finely-divided spray. The casing comprises at least two wall parts (1, 2) sealed to each other with the conduit (5) being formed between adjacent layers in a seam (4) connecting the wall parts (1, 2) by weakening the seam in the conduit (5) area so that when the package is pressed the area of the conduit opens to make the substance available for use. The weakening can be formed by including a depression in the sealing tool used to seal the seam (4) so that the seal in the area of the conduit (5) is not as firm as elsewhere. Alternatively a layer of plastics material or a coloured substance to mark the position of the conduit can be applied prior to sealing so that the strength of the seal in the area of the conduit is weakened.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
144 words
A disposable portion package for liquids, pastes, creams, powders or the like, the package comprising a casing (1,2) made of a flexible film adapted to enclose the packaged substance and also a certain amount of air or some other gas, the package having at least one conduit (5,13) or the like arranged to open by means of pressure produced inside the package, for example by pressing the package between the fingers, in order to obtain the contents for use, preferably as a finely-divided spray, the package comprising at least two wall parts (1,2) sealed to each other characterized in that the conduit (5,13) is formed between adjacent layers in a seam (4) connecting the wall parts (1,29,10) by weakening the seam in the conduit area (5,13) so that when the package is pressed the conduit area opens to make the substance available for use.
Claim 2
Dependent Claim
144 words
A disposable portion package for liquids, pastes, creams, powders or the like, the package comprising a casing (1,2) made of a flexible film adapted to enclose the packaged substance and also a certain amount of air or some other gas, the package having at least one conduit (5,13) or the like arranged to open by means of pressure produced inside the package, for example by pressing the package between the fingers, in order to obtain the contents for use, preferably as a finely-divided spray, the package comprising at least two wall parts (1,2) sealed to each other characterized in that the conduit (5,13) is formed between adjacent layers in a seam (4) connecting the wall parts (1,29,10) by weakening the seam in the conduit area (5,13) so that when the package is pressed the conduit area opens to make the substance available for use.
Claim 3
Dependent Claim
12 words
A package according to claim 1 wherein the conduit (5,13) converges outwardly.
Claim 4
Dependent Claim
39 words
A package according to claim 1 or claim 2, wherein the conduit (5) has been formed in the seam (4) connecting the wall parts (1,2) by weakening the seam in a manner known per se at the conduit (5).
Claim 5
Dependent Claim
23 words
A package according to claim 3, wherein the conduit (5) is open at its inner end portion and delimited by the packaging space.
Claim 6
Dependent Claim
25 words
A package according to claim 4 wherein the conduit (5) is open except that it has a narrow transverse seam (7) which closes the conduit.
Claim 7
Dependent Claim
54 words
A package according to any one of the preceding claims wherein the weakening of the seam (4) in the area of the conduit (5) is obtained by making the sealing pressure employed in sealing the seam (4) lower in this area by means of, for example, a depression or gouge in the sealing tool.
Claim 8
Dependent Claim
48 words
A package according to any one of claims 1 to 5 wherein the weakening of the seam (4) at the conduit (5) is obtained by applying, before sealing, some substance, e.g. a plastics material to the area concerned, which sucstance makes the sealing weaker in the said area.
Claim 9
Dependent Claim
77 words
A package according to claim 1 or claim 2 wherein the said conduit is formed between the one of the two wall parts (2) and a support film (9) or the like connected to the former, a thin layer (13) of a substance, dye or the like being applied directly or indirectly over the surface of the film (9) in the area of the seam (4) with the purpose of producing a weakening for forming the conduit.
Claim 10
Dependent Claim
58 words
A package according to claim 8 wherein the support film (9) is attached to the said one film (2) of the package by means of an intermediate film (10) so that the said substance is located either between the support film (9) and the intermediate film (10) or between the intermediate film (10) and the said film (2).
Claim 11
Dependent Claim
50 words
A package according to claim 9 wherein the said one film (2) and the intermediate film (10) are each substantially thinner than the other film (1) of the package and, taken either together or separately, preferably have a thickness approximately 1/5 to 1/100 of the thickness of the film (1).
Claim 12
Dependent Claim
58 words
