Abstract
Abstract A package particularly one designed for a single use, comprises at least one layer of material having an interior cavity which may, for example, be pear-shaped or spherical in form. The cavity is surrounded on all sides by the material of the package, and it forms a space within the package for the filling. A hollow tubular body is connected into the cavity at one end and it provides a means for the passage of the filling material. It includes a part which is surrounded in a fixed position by the material of the package which extends along a longitudinal portion thereof and another part which is surrounded loosely by the packaging material. The loosely surrounded part of the hollow tubular body serves as an area to open the package and the package is provided with a tear area or line extending through a point between the loosely surrounded portion of the hollow body and the fixed portion of the hollow body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A package construction, particularly a package designed for a single use, comprising at least a single layer material having an interior cavity surrounded on all sides by said material forming a space to receive the filling and which is provided with means for opening the package, a hollow tubular body connected to the cavity for the passage of the filling material whose one part is surrounded fixedly in longitudinal direction by said material and whose other part is surrounded loosely in longitudinal direction by said material, the loosely surrounded part of said hollow body serving to open the package and the boundary of said material between the fixedly and the loosely surrounded hollow body having tear-off area extending across the package defining a preset breaking point.
Claim 2
Dependent Claim
126 words
A package construction, particularly a package designed for a single use, comprising at least a single layer material having an interior cavity surrounded on all sides by said material forming a space to receive the filling and which is provided with means for opening the package, a hollow tubular body connected to the cavity for the passage of the filling material whose one part is surrounded fixedly in longitudinal direction by said material and whose other part is surrounded loosely in longitudinal direction by said material, the loosely surrounded part of said hollow body serving to open the package and the boundary of said material between the fixedly and the loosely surrounded hollow body having tear-off area extending across the package defining a preset breaking point.
Claim 3
Dependent Claim
14 words
A package construction, according to claim 1, wherein said hollow body comprises a tubule.
Claim 4
Dependent Claim
36 words
A package construction, according to claim 1, wherein said hollow body includes a substantially elliptical portion which is affixed in said material with the portion thereof which is loosely placed in the material being substantially tubular.
Claim 5
Dependent Claim
29 words
A package construction, according to claim 3, wherein the length of said tubular part is in the ratio of at least 1:1 of the length of the elliptical portion.
Claim 6
Dependent Claim
93 words
A package comprising a container formed with an interior cavity and with a tear-away portion spaced from said cavity, a tubular hollow body disposed in said container wall with one end in communication with the cavity and an opposite end extending into said tear-away portion, said opposite end being loosely fitted in said tear-away portion, and a weakened area defined between said tear-away portion and the remainder of said container defining a weakened area to permit tearing away of said tear-away portion to uncover the loosely fitted portion of said hollow tubular member.
Claim 7
Dependent Claim
93 words
A package comprising a container formed with an interior cavity and with a tear-away portion spaced from said cavity, a tubular hollow body disposed in said container wall with one end in communication with the cavity and an opposite end extending into said tear-away portion, said opposite end being loosely fitted in said tear-away portion, and a weakened area defined between said tear-away portion and the remainder of said container defining a weakened area to permit tearing away of said tear-away portion to uncover the loosely fitted portion of said hollow tubular member.
Claim 8
Independent Claim
123 words
A method of forming a container, comprising forming a cavity into a sheet of material to define a filling space, positioning a hollow tubular member over the sheet of material with one end connected into said cavity and an opposite end extending outwardly therefrom terminating short of the end of said sheet of material, and placing another material over the first material and securing it to the first material in the area surrounding said cavity and tightly around a portion of the length of said hollow tubular member with the remaining portion being left loosely surrounded, and defining a weakened area across both sheets of material intercepting the portion of said hollow tubular member which is loosely surrounded by the sheets of material.
