Abstract
Abstract A picture album comprising picture carriers which are formed by flat cells of double-walled plastic film, the flat cells being filled with an elastic material and being joined together by strip-like weld areas which form a folding hinge means. According to the invention each two flat cells are joined by a weld area to form double flat cell arrangements. Further there is formed in the weld area of a double flat cell arrangement, an insertion opening which extends in the longitudinal direction of the weld area, for at least one further double flat cell arrangement, and there is provided in the weld area of the further double flat cell arrangement a respective slot extending inwardly thereof from each of the upper and lower edges whereby a plurality of double flat cell arrangements are adapted to be joined together to constitute a book form by insertion of at least one of the further double flat cell arrangements into the insertion opening.

Claim 1
Independent Claim
160 words
A picture album comprising picture carriers which are formed by flat cells of double-walled plastic film, the flat cells being filled with an elastic material and being joined together by strip-like weld areas which form a folding hinge means, characterised in that each two flat cells are joined by a weld area to form double flat cell arrangements, that there is formed in the weld area of a double flat cell arrangement, an insertion opening which extends in the longitudinal direction of the weld area, for at least one further double flat cell arrangement, and that there is provided in the weld area of the further double flat cell arrangement a respective slot extending inwardly thereof from each of the upper and lower edges whereby a plurality of double flat cell arrangements are adapted to be joined together to constitute a book form by insertion of at least one of the further double flat cell arrangements into the insertion opening.
Claim 2
Dependent Claim
160 words
A picture album comprising picture carriers which are formed by flat cells of double-walled plastic film, the flat cells being filled with an elastic material and being joined together by strip-like weld areas which form a folding hinge means, characterised in that each two flat cells are joined by a weld area to form double flat cell arrangements, that there is formed in the weld area of a double flat cell arrangement, an insertion opening which extends in the longitudinal direction of the weld area, for at least one further double flat cell arrangement, and that there is provided in the weld area of the further double flat cell arrangement a respective slot extending inwardly thereof from each of the upper and lower edges whereby a plurality of double flat cell arrangements are adapted to be joined together to constitute a book form by insertion of at least one of the further double flat cell arrangements into the insertion opening.
Claim 3
Dependent Claim
58 words
A picture album as set forth in claim 1 characterised in that said insertion opening is formed in the weld area (3) of a double flat cell arrangement (1) by a loop picture (6) which is formed by two slots (5) which extend in the longitudinal direction of the weld area and which are closed at both ends.
Claim 4
Dependent Claim
59 words
A picture album as set forth in claim 1 characterised in that the insertion opening is formed by a slot (25) which is closed at both ends, whereby the double flat cell arrangements (21 and 28) are adapted to be fitted into each other in a crossed configuration and can thereby be joined together to constitute a book form.
Claim 5
Dependent Claim
38 words
A picture album as set forth in claim 2 characterised in that the slots (9) which project in from the edge of the weld area are enlarged at their closed end to form a preferably rounded opening (12).
Claim 6
Dependent Claim
43 words
A picture album as set forth in claim 2 characterised in that the loop portion (6) is arranged symmetrically with respect to the longitudinal axis of the weld area (3) and the slots (9) extending from the edge thereof are of equal length.
Claim 7
Dependent Claim
84 words
A picture album as set forth in claim 3 characterised in that the slot (25) which is closed at both ends, in one double flat cell arrangement (21), is disposed at a position which is displaced towards one side relative to the centre of the associated weld area (23), and the two slots (29) of the further double flat cell arrangement (28) are disposed at a position which is displaced towards the opposite side relative to the centre of the weld area (23) thereof.
Claim 8
Dependent Claim
56 words
A picture album as set forth in claim 6 characterised in that the slot (25) which is closed at both ends, in said one double flat cell arrangement, and the two slots (29) in said further double flat cell arrangement are displaced by the same extent out of the centre of the associated weld area (23).
