The tray part is suitable for displaying the product e.g. for retail. The box is strengthened by top side flaps whose bottom edges abut the base of the box and the top edge of the bottom side flaps. ## Claims ### Claim 1 A box formed of a folded blank and having a closed structure having top, base and front and rear end faces and respective pairs of side flaps connected by fold lines respectively to said top and said base, said faces and flaps provided by said blank, and the box having breakable weakness lines allowing when broken complete separation of a top portion including at least part of said top from a remainder of the box, wherein the remainder constitutes a tray structure and wherein, prior to separation of said top portion, vertical support of said top portion on said tray structure is provided by: (a) contact of a said side flap attached to said top with said base; and (b) edge-to-edge contact of said side flap attached to said top with another said side flap attached to said base; and wherein said contacts (a) and (b) are provided by respective portions of said side flap attached to said top. ### Claim 2 (depends on 1) A box according to claim 1 wherein said side flap attached to said top has longer and shorter portions, with the longer portion providing said contact (a) and the shorter portion providing said contact (b). ### Claim 3 (depends on 1) A box according to claim 1 wherein said side flap attached to said top overlaps with and lies inside said side flap attached to said base without being adhesively secured thereto and is thereby held in position to achieve said contact (b). ### Claim 4 (depends on 1) A box according to claim 1 wherein one said weakness line is provided at a fold line joining said top to said rear end face. ### Claim 5 (depends on 1) A box according to claim 1 wherein one said weakness line is provided in said front end face between upper and lower edges thereof. ### Claim 6 (depends on 1) A box according to claim 1 wherein said tray structure has an upstanding wall all around said base. ### Claim 7 A method of forming and loading a box formed of a folded blank and having a closed structure having top, base and front and rear end faces and respective pairs of side flaps connected by fold lines respectively to said top and said base, said faces and flaps all provided by said blank, and the box having breakable weakness lines allowing when broken complete separation of a top portion including at least part of said top from a remainder of the box, wherein the remainder constitutes a tray structure and wherein, prior to separation of said top portion, vertical support of said top portion on said tray structure is provided by: (a) contact of a said side flap attached to said top with said base; and (b) edge-to-edge contact of said side flap attached to said top with another said side flap attached to said base; and wherein said contacts (a) and (b) are provided by respective portions of said side flap attached to said top, the method including the steps of: erecting the blank into a configuration where the top, base and front and rear faces are positioned to form the box and one of the sides of the box is closed while the other side is open; loading a product through the open side; and thereafter closing the open side. ### Claim 8 (depends on 7) A method according to claim 7 wherein erection of the box, filling of the box and closing of the open side are carried out continuously by machine. ### Claim 9 A blank for forming a box having, in one piece, at least the following portions: rectangular top, base and front and rear end faces of the box, connected by three parallel transverse fold lines; a pair of first side flaps connected by longitudinal fold lines to said base and having a height less than a height of said end faces; a pair of second side flaps connected by longitudinal fold lines to said top and each having (a) a first portion of a height substantially equal to the height of said end faces and (b) a second portion having a height such that in the erected box said second portion makes edge-to-edge contact with an upper edge of a corresponding said first side flap; two breakable weakness lines which, when broken, separate at least part of said top completely from said base. ### Claim 10 (depends on 9) A blank according to claim 9 wherein a first one of said weakness lines coincides with one said transverse fold line at one end of said top. ### Claim 11 (depends on 9) A blank according to claim 9 wherein a second one of said weakness lines is located in said front end face intermediately between its upper and lower edges. ### Claim 12 (depends on 1) A box according to claim 1 in a closed state containing a product or a plurality of products.
