Abstract
Abstract A method for the production of aseptic packings, particularly a single use packing such as an ampoule, etc., comprises a plurality of oppositely directed substantially identical indentations on a foil on each side of a fold line. Thereafter, the foil material is folded along the fold line to align the indentations so that they form half portions of individual containers. The foil sections are welded or otherwise sealed together so that they close the container around the juncture line. Each container indentation includes a neck portion terminating in an outwardly widening funnel opening adjacent the edge of the foil material. The individual containers are then filled through the funnel and the neck portion is thereafter sealed directly below the bottom of the funnel by pressure welding. The area adjacent the closed weld line is provided with tear lines to facilitate easy opening and removal of the contents from the containers. An aseptic packing comprises a strip of two superposed foil sheets, each having aligned recessed portions forming container halves which together form a complete closed container which is closed around the periphery by the foil material. The strip includes tear line portions for both separating individual containers from the strip and for opening the mouth of each container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
189 words
A method for producing an aseptic package, particularly a one-time use container, such as an ampoule, using one or more foil sheets, comprising forming in the foil sheet a plurality of depressions in the outline of a container each depression including a container body depression and a container mouth depression extending outwardly from said body depression and including an outer funnel-shaped filling depression, said depression being formed at spaced locations along the length of a respective foil sheet, superimposing two sheet portions over one another with one row of depressions arranged over the other so as to align the depressions in a position in which they form complimentary portions of a whole individual container with a mouth and a filling funnel, securing the foil sheet portions together around the periphery of the whole containers and mouth except at the outer end of the mouths, filling the container through the mouths, sealing the foil material across the mouth to close the filled container, and forming a break line across the foil sheet to define a tear line for facilitating the severance of the material through the plane of the mouth.
Claim 2
Independent Claim
189 words
A method for producing an aseptic package, particularly a one-time use container, such as an ampoule, using one or more foil sheets, comprising forming in the foil sheet a plurality of depressions in the outline of a container each depression including a container body depression and a container mouth depression extending outwardly from said body depression and including an outer funnel-shaped filling depression, said depression being formed at spaced locations along the length of a respective foil sheet, superimposing two sheet portions over one another with one row of depressions arranged over the other so as to align the depressions in a position in which they form complimentary portions of a whole individual container with a mouth and a filling funnel, securing the foil sheet portions together around the periphery of the whole containers and mouth except at the outer end of the mouths, filling the container through the mouths, sealing the foil material across the mouth to close the filled container, and forming a break line across the foil sheet to define a tear line for facilitating the severance of the material through the plane of the mouth.
Claim 3
Dependent Claim
78 words
A method, according to claim 1, wherein the pairs of depressions are formed in rows on a single sheet of foil material and arranged in mirror-like fashion with the mouths or respective rows oriented in respective opposite directions, and including folding the material between the rows of said depressions in order to place one sheet portion on one side of the fold line in juxtaposition with the sheet portion on the other and to align the depressions together.
Claim 4
Dependent Claim
46 words
A method, according to claim 1, wherein said funnel-shaped portions extend in an outwardly flaring direction from said mouth to the adjacent edge of each said foil sheet and including sealing the foil material by welding the material directly below said funnel portion across said mouth.
Claim 5
Dependent Claim
34 words
A method, according to claim 1, wherein said permanent depressions of each row are formed on separate foil sheets and wherein said foil sheets are placed in juxtaposition to form said whole individual containers.
Claim 6
Dependent Claim
30 words
A method, according to claim 4, wherein one of said sheets is fed into juxtaposition with the other by feed-it along an angle extending at 90* to the other sheet.
Claim 7
Dependent Claim
21 words
A method, according to claim 3, including removing the funnel formation from the mouth after the mouth is closed by welding.
Claim 8
Dependent Claim
71 words
A method, according to claim 1, including a break line across said foil sheets to define weakened areas extending above the ends of said mouth with down turned portions terminating on each side of said mouth adjacent the closed end thereof, sand perforation line defining a movable tear strip which may be torn across the defined smooth projections on each side of said mouth and a tear line across said mouth.
Claim 9
Independent Claim
158 words
A method of producing aseptic packages, particularly ampoules from a plastic foil or plastic-coated foil or sheet, comprising forming in a horizontally arranged foil a plurality of oppositely facing and/or aligned sets of mouth and funnel-shaped depressions at spaced locations along the foil, each depression including a wide body portion tapering to a filling mouth portion and a filling mouth portion having an intermediate uniform diameter portion with an outwardly flaring funnel-shaped filling end; after submitting the foil to a sterilization treatment, folding the foil about a central fold line between the sets of depressions to move each sheet portion upwardly into interengagement so as to align the depressions of the oppositely facing set so that they form complementary portions of a whole individual container body, container mouth and filling funnel, filling the container through the filling funnel, and thereafter closing the container By forming a seal across said intermediate uniform diameter portion adjacent said filling funnel-shaped end.
Claim 10
Independent Claim
158 words
A method of producing aseptic packages, particularly ampoules from a plastic foil or plastic-coated foil or sheet, comprising forming in a horizontally arranged foil a plurality of oppositely facing and/or aligned sets of mouth and funnel-shaped depressions at spaced locations along the foil, each depression including a wide body portion tapering to a filling mouth portion and a filling mouth portion having an intermediate uniform diameter portion with an outwardly flaring funnel-shaped filling end; after submitting the foil to a sterilization treatment, folding the foil about a central fold line between the sets of depressions to move each sheet portion upwardly into interengagement so as to align the depressions of the oppositely facing set so that they form complementary portions of a whole individual container body, container mouth and filling funnel, filling the container through the filling funnel, and thereafter closing the container By forming a seal across said intermediate uniform diameter portion adjacent said filling funnel-shaped end.
Claim 11
Dependent Claim
51 words
A method according to claim 8, including defining a tear line extending along said folded portions of said foils to facilitate tearing along the intermediate uniform diameter portion to open this portion and provide a filling connection for a pipe bed or nozzle for withdrawing the contents of the container portion.
Claim 12
Dependent Claim
42 words
A method according to claim 9, wherein the tear line defined on the sheets terminates at a spaced location from the intermediate mouth portion so that a safety margin securing the container closed on all sides to insure its tightness is maintained.
