Abstract: A container having a first piece and a complementary second piece closable over the first is disclosed. Each container piece has a bottom wall and sidewalls having central portions which are connected to the bottom wall. Each of a first pair of opposite sidewalls of each piece has an upstanding tab portion extending from the top edge of its central portion. Each of a second pair of opposite sidewalls for each piece includes two spaced-apart upstanding portions for receiving an associated tab portion therebetween to interlock the container pieces. The opposing upstanding portions for each side wall each have a boss portion for engaging a side of the tab portion of a complementary piece.

Abstract: A lamp wrapper is formed from a blank having four side wall panels and a joint forming flap interconnected by a set of spaced, substantially parallel fold lines and adapted to form a tubular sleeve. An axial central partition is formed by a partition flap formed in part from and foldably connected to a first top wall panel and adhesively connected at its opposite end to a second partition flap formed from and foldably connected to a second wall panel located on the opposite side of the wrapper to the first panel. The partition is evenly spaced from opposite longitudinal ends of the sleeve and functions to separate the base ends of a pair of light bulbs packaged in the sleeve. In a second embodiment the second wall panel is extended and is foldably connected to yet another wall panel which in turn is connected to a second top panel which connects to the first top panel and defines a second sleeve in side by side relationship with the first sleeve.

Abstract: A two piece container including a tray piece for holding an item and a cover piece adapted to telescopically fit over the tray is disclosed. Each container piece has a first wall and sidewalls which extend from and taper outwardly from the first wall. The sidewalls of the tray piece meet at corners which have cut-out sections to provide for inward flexibility of the tray sidewalls when the cover is fitted over the tray. A blank for forming the tray piece according to the present invention is also disclosed.

Abstract: A container suitable for packaging food items such as hamburgers or fried chicken is disclosed. The container includes two complementary container pieces, namely a tray and a cover closable over the tray. Each piece has opposing sidewalls provided with tip portions which project longitudinally outwardly over the central portion of each adjacent sidewall without such tip portions to pass through a plane determined by the central portion of each such adjacent sidewalls. The tip portions of each complementary piece interlock to securely close the container.

Abstract: A mailer bag is fabricated from a rectilinear blank formed of paper, paperboard or the like and has two parallel score lines for folding, with one of the panels having a plurality of equally spaced, parallel cuts formed therein extending from one leading edge for a major portion of the length along the panel to a location near the opposite edge so that when folded over and glued, the uncut section serves to seal one end of the mailer. Glue is applied to alternate sites on the two end, or outer, panels so that when the cut end panel is folded over to meet with the center panel, and the other end panel is folded over on top of the other two panels, the cut panel sections will adhere in an alternating manner to the appropriate glued matching sections of the other two panels.

Abstract: A rack for the display of magazines and the like on a horizontal surface or alternatively on a pair of vertically spaced-apart horizontal rails includes a container having a back wall, a floor, right and left sidewalls and front margin portions adjacent the floor and sides, a strut member adapted for extension rearward and downward from the back wall and a brace member adapted for extension rearward from the back wall to engage the strut member at a location spaced from the back wall to secure the strut member at an acute angle to the back wall for support of the container on a horizontal surface as an easel, and a flap extending rearward from the back wall for interengagement with a pair of vertically spaced-apart horizontal rails, whereby the container can selectively be displayed on the horizontal surface or on the rails.

Abstract: Reinforced single-face corrugated fiberboard containers of remarkable strength are disclosed which can be mass produced at minimum cost in a high-speed continuous process from a continuous sheet of single-face corrugated material comprising a corrugated web adhesively secured to a single facing sheet having a width much greater than that of the web to provide outwardly extending fly portions of substantial width. The web forms the corrugated core of a single-wall laminated board formed by turning over the fly portions to reinforce the side edges and adhesively securing the fly portions to the corrugations to partially cover the core and to provide the board with double-faced side portions and an unreinforced single-faced middle portion.
