Abstract
Abstract A container of a pliable material comprises a tubular wall having an upper marginal portion, an upper end wall connected to the marginal portion of the tubular wall, and two suspension elements located opposite to one another and connected to the marginal portion of the tubular wall. Each of the suspension elements forms a loop having an interior and is provided with two side edge portions spaced from one another in a transverse direction and laterally bounding the interior. Each of the side edge portions is provided with a hem fixedly connected to the marginal portions of the tubular wall by means of seams. The seams comprise at least two first seams extending in a longitudinal direction of the suspension elements and spaced from one another in the transverse direction and at least two second seams intersecting one another and extending between the first seams at an angle to the latter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
211 words
A container of a pliable material, comprising a tubular wall having an upper marginal portion and an upper edge; an upper end wall connected to said marginal portion of said tubular wall; and two lifting sleeves located opposite and substantially parallel to one another and connected to said marginal portion of said tubular wall, each of said lifting sleeves forming a loop continuously extending in a transverse direction of said tubular wall and having an interior extending in said transverse direction, each of said lifting sleeves having two side edge portions spaced from one another in a transverse direction and laterally bounding said interior, each of said side edge portions being provided with a hem fixedly connected to said marginal portion of said tubular wall by means of seams comprising at least two first seams extending in a longitudinal direction of said lifting sleeves and spaced from one another in said transverse direction and at least two second seams intersecting one another and extending between said first seams at an angle to the latter, each of said second seams having an upper end portion closest to said upper edge of said tubular wall and provided with a locking seam extending substantially parallel to the locking seam of the other second seam.
Claim 2
Dependent Claim
211 words
A container of a pliable material, comprising a tubular wall having an upper marginal portion and an upper edge; an upper end wall connected to said marginal portion of said tubular wall; and two lifting sleeves located opposite and substantially parallel to one another and connected to said marginal portion of said tubular wall, each of said lifting sleeves forming a loop continuously extending in a transverse direction of said tubular wall and having an interior extending in said transverse direction, each of said lifting sleeves having two side edge portions spaced from one another in a transverse direction and laterally bounding said interior, each of said side edge portions being provided with a hem fixedly connected to said marginal portion of said tubular wall by means of seams comprising at least two first seams extending in a longitudinal direction of said lifting sleeves and spaced from one another in said transverse direction and at least two second seams intersecting one another and extending between said first seams at an angle to the latter, each of said second seams having an upper end portion closest to said upper edge of said tubular wall and provided with a locking seam extending substantially parallel to the locking seam of the other second seam.
Claim 3
Dependent Claim
17 words
A container as defined in claim 1, wherein said first seams are parallel relative to one another.
Claim 4
Dependent Claim
13 words
The container as defined in claim 1, wherein said tubular wall is cylindrical.
Claim 5
Dependent Claim
13 words
The container as defined in claim 1, wherein said tubular wall is prismatic.
Claim 6
Dependent Claim
14 words
The container as defined in claim 4, wherein said upper end wall is rectangular.
Claim 7
Dependent Claim
14 words
The container as defined in claim 4, wherein said upper end wall is square.
Claim 8
Dependent Claim
96 words
The container as defined in claim 1, wherein each of said locking seams has an upper end closest to said upper edge of said tubular wall and a lower end downwardly spaced from said upper end, said locking seams extending at an acute angle relative to said side edge portion of the respective lifting sleeve so that said upper end of said locking seam is spaced from said side edge portion by a distance greater than the distance by which said lower end of the same locking seam is spaced from the same side edge portion.
Claim 9
Dependent Claim
69 words
The container as defined in claim 1, wherein each of said lifting sleeves has two lower marginal parts connected to said tubular wall and a looped upper part forming a handle, said side edge portions of each of said lifting sleeves being slanted relative one another so that each of said lower marginal parts is of a length exceeding the length of said upper part in said transverse direction.
Claim 10
Dependent Claim
58 words
The container as defined in claim 1, wherein said upper end wall is quadrangular and bounded by lateral sides, each of said lifting sleeves having two lower marginal portions each extending along the respective lateral side of said upper end wall and being of a length less than the length of said lateral side in said transverse direction.
Claim 11
Dependent Claim
65 words
The container as defined in claim 1, wherein said first seams comprise one seam inwardly spaced from the other in said transverse direction; and further comprising a third seam connecting each of said hems with the associated lifting sleeve, said third seam extending in said longitudinal direction in alignment with said one seam of said first seams so as to form therewith a composite seam.
