Abstract

A one-piece folded box or carton for enclosing a lamp of the type having a shade assembly and an extensive counter-balanced arm assembly. The box has a cubical compartment at the bottom in which the shade assembly of the lamp is firmly supported, and there is an upstanding cavity which encloses the arm assembly of the lamp. When the carton is assembled, the various panels are held together by integral tabs which mate with slots during assembly and provide a rigid structure. There are also fold-in panels which interfit with the contour of the lamp and provide firm cushioned support.

CARTON FOR LAMP AND THE COMBINATION THEREOF This invention relates to storage and shipping cartons, and more particular to cartons for lamps of the type having a shade assembly and an extensible counterbalanced arm assembly.

An object of this invention is to provide compact and sturdy cartons for lamps of the type referred to above. A further object is to provide a one-piece carton which is readily assembled and which protects the lamp from damage. Another object is to provide a carton of the above nature into which the lamp is received in snug, secure manner with a minimum amount of free space within the carton so as to provide a high ratio of weight relative to volume. A further object is to provide for the above with a carton for packaging a lamp which gives satisfactory protection for the lamp at all times. A still further object is to provide for the above with an arrangement wherein the lamp and carton constitute a compact unit which is easily handled and stored, and with respect to which neither the lamp nor the carton is damaged during normal conditions. These and other objects will be in part obvious and in part pointed out below.

Referring to the drawings which show one embodiment of the invention:

FIG. 1 is a'perspective view ofa complete unit of the illustrative embodiment of the invention;

FIG. 2 is a vertical section on the line 2-2 of FIG. 1;

FIGS. 3 and 4 are sectional views, respectively, on the lines 3-3 and 44 of FIG. 2;

FIG. 5 is a perspective view of the lamp of FIGS. 1 to 4; and,

FIG. 6 is a plan view of the paperboard blank from which a carton of FIGS. 1 to S can be formed.

Referring to FIG. 1 of the drawings, a carton 2 has a somewhat cubical lower main cavity 4 which is open to an upper riser cavity 6 which is rectangular in crosssection. Near the top of cavity 6 there is a score line 8 along the sides and bottom of an area of the side wall which can be pushed in and hinged at the top to provide a handle. The carton (see FIGS. 6, 2 and 3) has panels forming

side walls

10 and 12, a bottom wall 14, a top wall 16, a rear wall 18, a lower front wall 20, an upper front wall 22, and a ledge or top wall 24. Wall 24 forms the top of the lower cavity 4, and extends between

front walls

20 and 22. Hence, a closed storage cavity is provided by the cubical cavity 4 at the bottom, and the riser cavity 6 which extends upwardly from the rear vertical side of cavity 4. Y

As shown in the drawings, a lamp 28 has its shade assembly 30 positioned in the cubical cavity 4, and the collapsed arm assembly 32 extending vertically into the riser cavity 6. The lamp shade 34 (FIG. 2 has a circular rim 35 at its flared end resting against the right-hand side wall 12, and the projecting left-hand end of a switch 37 at the small left-hand end or top 39 of the shade provides support at wall 38, as will be explained below. I

Referring to FIG. 6, a wall panel 38 is an extension of side wall 10 and is connected thereto by a narrow panel 40. A narrow panel 42 connects wall panel 38 to a wall panel 44, and during assembly ofthe carton (see also FIG. 2),

walls

38 and 44 and

strips

40 and 42 are folded in the manner shown so that a space 46 is provided between

walls

38 and 44. Wall 38 has a keyhole slot 48 (FIG. 6) into which the projecting end of the lamp switch 37 is nested so as to provide the abovementioned support for the end of the lamp shade.

Side wall 12 has a fold-in extension (FIG. 2) formed by

inter-connected panels

50, 52 and 54 which are po sitioned as shown when the lamp has been placed in the carton to form the assembled carton and lamp unit. The fold between

panels

50 and 52 is near shade 34, and panel 54 is bifurcated by a cutout with two legs 58 between which the shade is nested against a semicircular edge 60 so as to give support.

Front wall 20 and rear wall 18 have integral

bottom extension panels

62 and 64, respectively, which interfold to provide bottom wall 14. Front wall 20 has a top extension which forms

walls

24 and 22, and wall 18 has a top extension which forms top wall 16 and an inner wall panel 66 which is assembled behind and coextensive with wall panel 22. Each of

side walls

10 and 20 has three

extensions

70, 72 and 74 which are folded rearwardly as an initial step of assembly into the carton. Thereafter,

walls

10 and 12 are folded rearwardly from wall 20 and panel form horizontal ledges at the bottom edge of panel 24 so that wall 24 rests on those ledges when it is folded rearwardly. At the same time, wall 22 is folded forwardly with respect to wall 24, and wall 22 nests against panels 72. Panels 74 extend beneath wall 16, and, as indicated above, panel 66 is positioned behind wall 22. An extension panel 79 along the side of panel 18 is folded back and (see FIG. 4) fits in behind the edge of panel 10. During assembly: two tabs 76 on panel 24 are projected through slots 78 at the tops of

panels

10 and 12; two tabs 80 on panel 22 are projected through slots 82 on

panels

10 and 12; two tabs 84 on panel 10 are projected through slots 86 along the edges of

panels

18 and 79; and tab 88 on panel 22 is projected through slot 90 at the top of panel 16. A cutout 92 permits the portion above score line 8 to hinge inwardly to provide a handle, as discussed above.

In that way, carton 2 is fully assembled, and the lamp is inserted from the bottom between the

bottom panels

62 and 64. As indicated above, the projecting end of the switch assembly is inserted in the keyhole slot and

panels

50, 52 and 54 are moved into position as shown in FIG. 2. Lamps of this type have a mounting bracket 95 which is fixed to a table or other base, and

panels

50 and 52 provide a pocket 94 adjacent the bottom wall in which-the mounting bracket is nested. Referring to FIGS. 4 and 6, panel 52 has a cutout 96 into which the corner of the mounting bracket projects so as to anchor it in place. The

bottom walls

62 and 64 are then folded into place and are secured to each other by adhesive.

The unit comprising the carton and the enclosed lamp is compact and easily handled. The lamp provides rigidity and yet it is protected from damage, even when the package is subjected to normal abuse. The structure formed by

panels

38, 40, 42 and 44 provides rein forcement from the front and rear walls and resists a tendency for the corner of the carton to be twisted or deformed.

Panels

50, 52 and 54 perform a similar reinforcing function. The center of gravity ofthe entire unit is to the left ofthe upper portion of panel 54 so that the package is properly balanced for being supported from the top handle. Panel 66 and wall 22 cooperate to insure the desired rigidity relative to

walls

18 and 24.

Walls

20 and 22 are the same size so that one unit can be inverted and mated with another with the two walls 24 co-extensive and each wall 20 extending along a wall 22. The two units occupy a rectangular upight space so that they can be stored and shipped without space between them. The lamps and cartons are fully protected from damage, and yet the weight per volume is relatively high.
