Abstract
Abstract A door construction for a shipping container. (1) to ISO standard is provided in which there is a main frame (6) arranged to be pivotally mounted on the door frame on the container, locking means (8,9) mounted on the door (2,3) within the profile of the door so that the opposed ends of the locking means (8,9) extend beyond opposed edges of the main frame and seal means (13) extending around the edges of the main frame which are to be engaged with the container door frame for sealing the door (2,3) relative to the container (1), the seal (13) at least in the region of the locking means being offset inwardly of the locking means. The construction permits the door (2,3) and its locking members (8,9) to be within the wall profile yet maintain sealing round the door.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A door for a container, comprising two major opposed sides between which extends an outer peripheral edge surface, locking means (8, 9) mounted on the door (2, 3) within the profile of the door so that the locking means extends beyond the outer peripheral edge surface of the door and seal means (13) located on the door for sealing the door within a door frame of the container, characterized in that the seal means (13) extends around the outer peripheral edge surface of the door for engagement with the container door frame for sealing the door relative to the container, the seal means and locking means lying substantially in the same place extending through the door parallel to the two major sides and where the locking means extend beyond the outer peripheral surface the seal means is offset relative to the locking means, thereby to minimize the effective door thickness.
Claim 2
Dependent Claim
150 words
A door for a container, comprising two major opposed sides between which extends an outer peripheral edge surface, locking means (8, 9) mounted on the door (2, 3) within the profile of the door so that the locking means extends beyond the outer peripheral edge surface of the door and seal means (13) located on the door for sealing the door within a door frame of the container, characterized in that the seal means (13) extends around the outer peripheral edge surface of the door for engagement with the container door frame for sealing the door relative to the container, the seal means and locking means lying substantially in the same place extending through the door parallel to the two major sides and where the locking means extend beyond the outer peripheral surface the seal means is offset relative to the locking means, thereby to minimize the effective door thickness.
Claim 3
Dependent Claim
54 words
A door as claimed in claim 1, characterized in that the locking means (8, 9) extends vertically and the seal means (13) extends along top and bottom outer peripheral edge surface portions of the door and is offset inwardly towards the inside of the door for engagement with the door frame of the container.
Claim 4
Dependent Claim
36 words
A door as claimed in claim 1, characterized in a flange (16) extending inwardly of the door for supporting the seal means along each of top and bottom outer peripheral edge surface portions of the door.
Claim 5
Dependent Claim
41 words
A door as claimed in claim 1, characterized in that the locking means (8, 9) comprises one or more elongate bars (9) extending vertically of the door and projecting from top and bottom outer peripheral edge surface portions of the door.
Claim 6
Dependent Claim
19 words
A door as claimed in claim 1, characterized in that the door seal (13) is of a rubber material.
Claim 7
Dependent Claim
19 words
A door as claimed in claim 1, characterized in that the door seal (13) is of a plastics material.
Claim 8
Dependent Claim
23 words
A door as claimed in claim 1, characterized in that the door comprises a main frame (7) and a corrugated panel located therein.
Claim 9
Dependent Claim
161 words
A container for carrying cargo including a door comprising two major opposed sides between which extends an outer peripheral edge surface, locking means (8, 9) mounted on the door (2, 3) within the profile of the door so that the locking means extends beyond the outer peripheral edge surface of the door and seal means located on this door for sealing the door within a door frame of the container, characterized in that the seal means (13) extends around the outer peripheral edge surface of the door for engagement with the container door frame for sealing the door relative to the container, the seal means and locking means lying substantially in the same plane extending through the door parallel to the two major sides and where the locking means extends beyond the outer peripheral surface the seal means is offset relative to the locking means thereby to minimize the effective door thickness and maximize the cargo loading area within the container.
Claim 10
Dependent Claim
161 words
A container for carrying cargo including a door comprising two major opposed sides between which extends an outer peripheral edge surface, locking means (8, 9) mounted on the door (2, 3) within the profile of the door so that the locking means extends beyond the outer peripheral edge surface of the door and seal means located on this door for sealing the door within a door frame of the container, characterized in that the seal means (13) extends around the outer peripheral edge surface of the door for engagement with the container door frame for sealing the door relative to the container, the seal means and locking means lying substantially in the same plane extending through the door parallel to the two major sides and where the locking means extends beyond the outer peripheral surface the seal means is offset relative to the locking means thereby to minimize the effective door thickness and maximize the cargo loading area within the container.
