Double delivery cartridge for two component masses

Claim 2

A dual dispenser cartridge assembly for two-component compounds, comprising: two interlocked storage cylinders, separated by double walls, arranged axially parallel side-by-side, and each cylinder having one front end discharge opening, wherein both discharge openings are located next to each other centered on a common diametral plane through both storage cylinders, the distance between the axes of the discharge openings being less than the distance between the cylinder axes, said dual dispensing cartridge assembly being subject to long term storage and subsequent dispensing of said components; a transition member positioned ahead of the front end of the storage cylinders, said transition member having for both components a mounting for attachment of a mixer tube, and two discharge channels, extending separately to the extremity of the mounting, said transition member being undetachably integral with both storage cylinders and connecting both said discharge channels to said discharge openings of the storage cylinders, said transition member defining a rigid unit in conjunction with both said storage cylinders; and means for rendering said transition member undetachably integral with said cylinders.

Claim 3

Dual dispenser cartridge assembly as defined in claim 1, wherein the transition member is manufactured as a separate injection-molded component, and said means for rendering comprises a snap lock connection.

Claim 4

Dual dispenser cartridge assembly as defined in claim 1, wherein the two discharge channels within the transition member are separated by double walls along their entire length.

Claim 5

Dual dispenser cartridge assembly as defined in claim 1, wherein each of the discharge openings is defined by a respective circular stud, and the transition member comprises a region which sealingly overlaps the two studs.

Claim 6

Dual dispenser cartridge assembly as defined in claim 4, wherein for both storage cylinders the distance of the axis of the stud from the inner cylinder wall is equal.

Claim 7

Dual dispenser cartridge assembly as defined in claim 4, wherein the stud of at least one of the two storage cylinders is arranged eccentrically with respect to the cylinder axis.

Claim 8

Dual dispenser cartridge assembly as defined in claim 1, wherein the two storage cylinders define an integral unit.

Claim 9

Dual dispenser cartridge assembly as defined in claim 7, wherein the two storage cylinders are interlocked near their rear and front ends by means of connecting webs.

Claim 10

Dual dispenser cartridge assembly as defined in claim 1, wherein the two storage cylinders are separately manufactured and are interlocked, at least near their rear ends, by means of one of a plug-in and snap-lock connection.

Claim 11

Dual dispenser cartridge assembly as defined in claim 9, wherein there is provided, preferably to the front ends of the two storage cylinders, a locking means to prevent respective longitudinal displacement thereof.

Claim 12

Dual dispenser cartridge assembly as defined in claim 1, wherein each of the two discharge channels is defined by two mutually overlapping longitudinal sections which are offset with respect to each other in an axially parallel arrangement.

Claim 13

Dual dispenser cartridge assembly as defined in claim 1, wherein the exit cross sections of the two discharge channels, within the transition member, are dimensioned in proportion to the cross section ratio of the two storage cylinders.

Claim 14

A cartridge assembly as in claim 1, wherein said means for rendering includes a permanent axial push fit connection between said cylinders and said transition member.

Claim 15

Dual dispenser cartridge assembly as defined in claim 1, wherein the discharge openings of the cylinders are arranged symmetrically with respect to the axis of the mounting, the latter having a circular cross-section.

Claim 16

A series of dual dispenser cartridge assemblies for two-component compounds, each assembly, comprising: two interlocked storage cylinders, separated by double walls, arranged axially parallel side-by-side, and each cylinder having one front end discharge opening, wherein both discharge openings are located next to each other centered on a common diametral plane through both storage cylinders, the distance between the axes of the discharge openings being less than the distance between the cylinder axes, said dual dispensing cartridge assembly being subject to long term storage and subsequent dispensing of said components; a transition member positioned ahead of the front end of the storage cylinders, said transition member having for both components a mounting for attachment of a mixer tube, and two discharge channels, extending separately to the extremity of the mounting, said transition member being undetachably integral with both storage cylinders and connecting both said discharge channels to said discharge openings of the storage cylinders, said transition member defining a rigid unit in conjunction with both said storage cylinders; means for rendering said transition member undetechably integral with said cylinders; each said assembly being of equally rated total volume, however, with variable ratios between the cross-sections of the cylinder pairs, wherein the distance between the cylinder axes for all the cylinder pairs of the series is equal.

Claim 17

A series of dual dispenser cartridge assemblies for two-component compounds, each assembly, comprising: two interlocked storage cylinders, separated by double walls, arranged axially parallel side-by-side, and each cylinder having one front end discharge opening, wherein both discharge openings are located next to each other centered on a common diametral plane through both storage cylinders, the distance between the axes of the discharge openings being less than the distance between the cylinder axes, said dual dispensing cartridge assembly being subject to long term storage and subsequent dispensing of said components; a transition member positioned ahead of the front end of the storage cylinders, said transition member having for both components a mounting for attachment of a mixer tube, and two discharge channels, extending separately to the extremity of the mounting, said transition member being undetachably integral with both storage cylinders and connecting both said discharge channels to said discharge openings of the storage cylinders, said transition member defining a rigid unit in conjunction with both said storage cylinders; means for rendering said transition member undetechably integral with said cylinders; each said assembly being of equally rated total volume, however, with variable ratios between the cross-sections of the cylinder pairs, wherein the distance between the cylinder axes for all the cylinder pairs of the series is equal.

Claim 18

A series as defined in claim 15, wherein the distance between the axes of the front end discharge openings is equal for all pairs of cylinders within the series.
