Abstract
Abstract The present invention relates to a storage container intended for loose stacking and transport of piece goods, e.g. cartons of milk, which has at least three wall members of which one is a front wall and the other two are side walls hingedly connected with at least one of the wall members and collapsable against the same. Said storage container is also convertible from a normal position in which it has essentially the form of a parallelepiped, to a stowing position requiring less space. The invention is mainly characterized in that the side walls are swingable out from their normal positions, in which they form essentially a 90* angle with the front wall, to outer positions appropriate for stowing the container, in which positions said angle is obtuse and in which the internal distance between the rear edges of the side walls is greater than the breadth of the front part of the container. The swinging outward of the side walls is limited at the outer positions by a blocking member, mounted on the side walls or parts connected to the side walls, stopping against the front wall or against parts connected thereto or vice versa.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
153 words
Storage container for loose stacking and transport of piece goods such as cartons of milk, said container having at least three wall members, one of which being a front wall and two of which being side walls hingedly connected to the front wall, and a bottom member hingedly connected to at least one of the wall members and being collapsible against said wall member, said container being convertible from a working condition giving said container essentially the form of a parallelepiped to a stowing condition giving said containers a space-saving form when stowed in a group together with other containers of the same kind, said side walls being swingable outwards at an acute angle from parallel positions in said working condition to outer positions in said stowing condition, blocking members being connected to said side walls limiting the swinging movement of said side walls by stopping against parts connected to said front wall.
Claim 2
Dependent Claim
153 words
Storage container for loose stacking and transport of piece goods such as cartons of milk, said container having at least three wall members, one of which being a front wall and two of which being side walls hingedly connected to the front wall, and a bottom member hingedly connected to at least one of the wall members and being collapsible against said wall member, said container being convertible from a working condition giving said container essentially the form of a parallelepiped to a stowing condition giving said containers a space-saving form when stowed in a group together with other containers of the same kind, said side walls being swingable outwards at an acute angle from parallel positions in said working condition to outer positions in said stowing condition, blocking members being connected to said side walls limiting the swinging movement of said side walls by stopping against parts connected to said front wall.
Claim 3
Dependent Claim
30 words
Storage container as defined in claim 1, wherein said bottom member is foldable against the wall to which it is hingedly connected when said container is in said stowing condition.
Claim 4
Dependent Claim
90 words
Storage container as defined in claim 2, wherein said bottom member is hingedly connected to said front wall, the side edges of said bottom member each being provided with a guide means having an oblique guide surface facing the adjacent one of said side walls, said guide surface striking against a part connected to the adjacent side wall when said bottom member is in the final stage of a folding-up motion against said front wall, said guide surfaces thereby forcing said side walls to swing outwards to Said outer positions.
Claim 5
Dependent Claim
45 words
Storage container as defined in claim 3, wherein said bottom member is spaced horizontally a short distance from said front wall when said container is in said stowing condition, said blocking members being bent arms rigidly mounted on the front edges of said side walls.
Claim 6
Dependent Claim
96 words
Storage container according to claim 4, characterized in that said blocking members comprise arms bent at an angle and rigidly mounted on the front edges of the side walls, which arms, in the normal position, make the container more rigid by pressing against the inside of the front wall and which swing in towards the interior of the container when the side walls swing outward and which stop against the folded-up bottom member, in the final stage of the collapsing of the container to the stowing position, thereby stabilizing the side walls in their outer positions.
Claim 7
Dependent Claim
19 words
Storage container as defined in claim 4, wherein means for moving said container are attached to said side walls.
Claim 8
Dependent Claim
103 words
Storage container as defined in claim 2, wherein said bottom member is hingedly connected to said front wall, said side walls each being provided with a guide means on an inner fore part of the wall, said guide means having an oblique guide surface facing said bottom member when being in a final stage of a folding-up motion against said front wall, said bottom member having parts connected to said member striking against said guide surfaces in said final stage of said folding motion, said parts connected to said bottom member thereby forcing said side walls to swing outwards to said outer positions.
Claim 9
Dependent Claim
165 words
Storage container intended for loose stacking and transport of piece goods such as cartons of milk, said container having four wall members and one bottom member, one of said wall members being a front wall, two wall members being side walls and one being a rear wall, said side walls being hingedly connected to said front wall, said bottom member and said rear wall being hingedly connected to at least one of said other four members, said container being convertible from a working condition giving said container essentially the form of a parallelepiped to a stowing condition giving said container a space-saving form when stowed in a group together with other containers of the same kind, said side walls being swingable outwards at an acute angle from parallel positions in said working condition to outer positions in said stowing condition, blocking members being connected to said side walls limiting the swinging movement of said side walls by stopping against parts connected to said front wall.
Claim 10
Dependent Claim
165 words
Storage container intended for loose stacking and transport of piece goods such as cartons of milk, said container having four wall members and one bottom member, one of said wall members being a front wall, two wall members being side walls and one being a rear wall, said side walls being hingedly connected to said front wall, said bottom member and said rear wall being hingedly connected to at least one of said other four members, said container being convertible from a working condition giving said container essentially the form of a parallelepiped to a stowing condition giving said container a space-saving form when stowed in a group together with other containers of the same kind, said side walls being swingable outwards at an acute angle from parallel positions in said working condition to outer positions in said stowing condition, blocking members being connected to said side walls limiting the swinging movement of said side walls by stopping against parts connected to said front wall.
Claim 11
Dependent Claim
30 words
Storage container as defined in claim 8, wherein said bottom member and said rear wall are hingedly connected to one of said side walls and collapsible against the same wall.
Claim 12
Dependent Claim
31 words
Storage container as defined in claim 8, wherein said bottom member and said rear wall are hingedly connected to one each of said side walls and collapsible against the same wall.
Claim 13
Dependent Claim
42 words
