Patented Sept. 23, 1952 TWOFLAMP WRAPPER New York Application February 25, 194.9,, Serial No. 78,332

My invention relates to packing c ntain r and is of particular interest in connection with wrappers for fragile articles, .such as incandescent lamps comprising glass-bulbs.

Objects of my invention are to provide a lamp wrapper in the form of asleeve for holding and protecting a pair of incandescent lamps. Other objects and advantages of the-invention will appear from the" following detailed description of species thereof and from the accompanying drawing in which'Fig. l is a perspective view of my novel wrapper with portions of its side Walls broken away to show its interior structure and a pair of lamps disposed therein; Fig. 2 is a similar view of the wrapper rotated 45 on its longitudinal axis from its position shown in Fig. 1 and before the lamps have been inserted therein, and Fig. 3 is a plan view of the blank from which the. wrapper is formed showing the scores and cuts therein proper for facilitatii-"lg the folding of the blank into the shape shown in Figs. 1 and 2.

Referring to Figs. 1 and 2 of'the drawing the completed wrapper is in the form of a sleeve I rectangular in cross-section-with a diagonal panel or partition 2 extending. longitudinally therein and dividing its interior into two triangular compartments 3 and 4. The pear-shaped incandescent lamps and 5 are thrust base end first into the compartments 3 and 4 on opposite sides of the partition 2 and from opposite ends of the sleeve I. The sleeve is so dimensioned and the partition so constructed that as the

lamps

5 and 5 are forced into the sleeve I the partition 2 is deformed as shown in Fig. 1 to fit between the lamps 5 and B and to act as a spacer, the split ends 01 the partition 2 are forced against the sides of the sleeve by the glass bulbs of the lamps 5 and 6 and the sleeves are expanded slightly so that the lamp bulbs are gripped thereby. The interior surfaces of the sleeve I have a corrugated paper lining I.

The lamps 5 and 6 are thus cushioned against shock, are firmly held against sliding and are spaced apart in the sleeve I.

The sleeve I is formed from the blank 8 shown in Fig. 3 which consists of a rectangular sheet of smooth surface paper 9 having the corrugated lining paper I pasted to and covering completely one of its sides except for a laterally extending strip I0 at one end which forms the pasting flap for holding the sleeve I together after it is folded as explained below. The lining paper I is scored along three spaced parallel transverse lines I I, I2 and I3 to facilitate folding of the blank at Y 4 Claims. (0!. 229+-90) the scores-to. form the four sides. or panels I4,

I5. 16 and I! of the sleeve I with the lining paperlinsidethe sleeve.

Thepartition. 2 is formed Icy-partially cutting and partially scoring the lining I along a line spaced from and parallel to the-score I3. The cuts I8 and I9 extend inward along the'line from opposite sides of the blank 8. and terminate an .equal distance from its median line. The lining 1 is. scored at 20 between the cuts, I8 and [9. The partitionf2- is also out at 2| and 22 along a line. parallel to the line including cuts I8. and I9,- and score 26 and midway between said line and the edge 23. of. the blank 8v to form the four

tongues

24, 25, 26 and 21. The cuts ZI and 22 areequal in length to the cuts I8 and 191,, the lining l is not scored between the cuts2l and 22 but the tongues 24 to 26. have. scores 28, 29, 3 0 and 31, respectively, extending diagonally from their outer adjacent corners to the blank edge 23, and the. inner ends of cuts I8 and I9 .so that they are easily deformedto fit and engage the lamps; 5 and 6 as, the latter are thrust base end first into the-sleeve I as described above and; as shown in Fig. 2.' .The partition 2 is thus integral with the sleeve I and the tongues 24 to 26 integral with the partition 2 to aid in holding the lamps 5 and 6 in the sleeve I.

In forming the sleeve the blank 8 is first/folded along the scores 20 and I3 until edge 23 meets score 2. The blank is then folded along scores I2 and II until the edge 32 of panel I4 meets the edge of panel I I formed by cuts I8 and I9. The flap I0 is then folded over and pasted to the outer surface of panel IT to complete the sleeve in the form shown in Fig. 2.. The lamps 5 and 6 may then be inserted in the sleeve I and are firmly held therein in the manner described above in connection with Fig. 1.

I prefer to make up a four lamp package for retail sales by inserting a pair of sleeves I in side-by-side position into a container or carton having open ends to receive the sleeves and so shaped that its sides cover the open ends of the sleeves. Cartons of this type are in common use for sleeves accommodating lamp.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. A wrapper for a pair of pear-shaped incandescent lamps comprising an elongated sleeve having substantially the same lateral dimensions as a sleeve designed to receive and grip but a single one of the lamps of the size for which the 1 wrapper is designed and comprising also a longia single incandescent 3 tudinal partition of flexible material integral with said sleeve and dividing its interior into longitudinally extending open-ended compartments, each end of said partition being split longitudinally so as to be separable laterally into two flexible portions to fit between the sides of the sleeve and the sides of the lamp bulbs when a pair of said lamps are thrust longitudinally base end first into opposite ends of the sleeve, on opposite sides of the partition and a sufiicient distance into the sleeve to overlap their respective base ends whereby the latter are spaced apart by said partition and the lamps are firmly gripped by said sleeve.

2. A wrapper for a pair of pear-shaped incandescent lamps comprising an elongated sleeve rectangular in cross section and having substantially the same lateral dimensions as a sleeve designed to receive and grip but a single one of the lamps of the size for which the wrapper is designed and comprising also a diagonal partition of flexible material integral with said sleeve and dividing its interior into longitudinally extending open ended compartments triangular in cross section, each end of said partition split longitudinally so as to be separable laterally into two flexible portions to fit between the sides of the sleeve and the sides of the bulb when a pair of said lamps are thrust longitudinally base end first into opposite ends of the sleeve, on opposite sides of the partition and a suificient distance into the sleeve to overlap their respective base ends whereby the latter are spaced apart by said partition and the lamps are firmly gripped by said sleeve.

3. A wrapper for a pair of pear-shaped incandescent lamps comprising an elongated sleeve rectangular in cross section and having substantially the same lateral dimensions as a sleeve designed to receive and grip but a single one of the lamps of the size for which the wrapper is designed and comprising also a diagonal partition of flexible material integral with and extending the full length of said sleeve and dividing its interior into longitudinally extending open ended compartments triangular in cross section, the

ends of said partition being cut longitudinally so as to be separable laterally into two flexible portions to fit between the sides of the sleeve and the sides of the bulb when a pair of said lamps are thrust longitudinally base end first into opposite ends of the sleeve, on opposite sides. of the partition and a sufficient distance into the sleeve to overlap their respective base ends whereby the latter are spaced apart by said partition and the lamps are firmly gripped by said sleeve.

4. A wrapper for a pair of pear-shaped incandescent lamps comprising an elongated sleeve rectangular in cross section and having substantially the same lateral dimensions as a sleeve designed to receive and grip but a single one of the lamps of the size for which the wrapper is designed and comprising also a diagonal partition integral with and extending the full length of said sleeve and dividing its interior into longitudinally extending open ended compartments triangular in cross section, the end portions of said partition being cut inwardly along the center lines thereof andscored along lines diverging from the outer ends of the cuts so as to be deformable when a pair of said lamps are thrust longitudinally base end first into opposite ends of the sleeve, on opposite sides of the partition and a suflicient distance into the sleeve to overlap their respective base ends whereby the latter are spaced apart by said partition.
