I (D '|0 E 2 l6 it; IS 54 56 D awn/m CONTAINERS FOR ELECTRICAL GLOBES R SIMILAR OBJECTS This invention relates to carton-type containers for incandescent electric light globes, or similar fragile objects and its object is to provide a new container of this type and a blank which may be erected to form such a container.

A globe for which the container is particularly suitable is the type having a metallic base adapted to be held in the socket of a lamp or light fitting, and a glass bulb seated in the metallic base, the bulb having a comparatively narrow waist adjacent the base, and an enlarged head.

According to one aspect of the invention a blank for an electric globe carton comprises an elongated rectangular strip having a holetherein adapted to receive the metallic base of the globe, a portion of the strip surrounding the hole being adapted to define a base for the carton, at least two openings in the strip on either side of the base portion, means to interconnect the two ends of the strip, and means to connect a portion of the strip in the vicinity of each of the openings to the base portion on opposite sides of the hole.

According to another aspect of the invention, a carton for an electric globe comprises a base portion having a hole therein adapted to receive the metallic base of an electric globe, and a loop portion adapted to surround the bulb of the globe, the two ends of the loop being connected to the base portion.

An embodiment of the invention is described below with reference to the accompanying drawings, in which:

FIG. 1 is a plan view of a blank adapted to be erected to form a carton to house an electric light globe;

FIG. 2 is an end elevation view of a carton-type container housing an electric globe, the carton being formed from the blank of FIG. 1;

FIG. 3 is a side elevation view of the carton of FIG. 2, the globe and certain fold lines being shown in chain lines; and

FIG. 4 is a semischematic end view of the carton of FIGS. 2 and 3 indicating in simplified form the fold pattern of the carton, the globe being shown in chain lines.

The blank of FIG. 1 is stamped or otherwise cut from a suitable stiff yet flexible material such as cardboard. Its outline and certain cuts in the body of the material are indicated in solid lines; fold lines are shown in the drawing by chain lines. The blank is preferably scored or otherwise sulcated along the fold lines to facilitate erection to form a carton.

The blank comprises a substantially rectangular strip divided into various zones, which will now be described seriatim, starting from the top of the drawing.

The uppermost zone in FIG. 1 is a short end zone in which are formed two arcuate cuts 16 which define lugs 17 for interconnecting the zone 10 in the erected carton to the other end of the strip. A circular hole 14 is also provided in the zone 10 for purposes unconnected with this invention. A transverse score line 18 separates the zone 10 from a rectangular zone 20 which is in the erected carton forms a vertical sidewall. The zone 20 is divided by a score line 22 from another rectangular zone 24 which provides the roof of the finished carton. The

zone 24 in its turn is divided by a score line 26 from a further zone 28 which in the erected carton forms a sidewall opposite that provided by the zone 20. Recesses 30 are provided in the sides of the zone 28.

Divided from the zone 30 a by a score line 32 is a zone 34, which in turn adjoins a further zone 36 and is divided from it by a score line 38. An opening 40 is formed in the

zones

34 and 36, straddling the line 38. The opening 40 has a domelike portion 42 at one longitudinal end and a scalloped portion 44 at the opposite end. Between the

portions

42 and 44 there is,

on each transverse side of the opening, a lug 46 projecting inwardly from the side of the strip. In the erected carton, the zone 34 forms a sloping wall abutting the central portion of the globe, and the zone 36 a panel through which the lower part of the globe protrudes, with the opening 40 embracing a part of the circumference of the globe in a manner to be described later.

.Below the zone 36 and divided from it by a score line 48 is a rectangular zone 50 which in the finished carton forms a skirt for the base of the carton.

The base zone or portion of the blank is provided by a zone 54 divided from the skirt zone 50 by a score line 52. The base zone 54 has a hole 56 formed centrally in it to receive the metallic base of the electric globe. At its side edges it has

ears

58,58, located on opposite sides of the hole 56 and adapted in the erected carton to receive and hold the lugs 46 described earlier.

Score lines

60,60 and 62,62 define a rectangular panel or space 55 within the zohe 54 surrounding the hole 56, and oblique score lines 64 connect the corners of the rectangular panel 55 to the corners of the zone 54. The corners of the rectangular panel 55 are also connected by oblique score lines 66 to the ends of the ears 58 on the sides of the strip. The

lines

60,62,64 and 66 define, with the sides of the zone 54 and

score lines

52 and 68, a total of four small triangular panels 57, two transversely elongated quadrangular panels 59, and two longitudinally elongated quadrangular panels 61.

Below the zone 54 and divided from it by a score line 68 is a rectangular zone 70 which is similar to the zone 50 described above. A score line 72 divides the zone 70 from a lower zone 74 which is similar to the zone 36. Finally, there are a score line 76 and a zone 78, with an opening straddling the line 76 and shaped similarly to the opening 40. Towards the edge of the zone 78 semicircular holes 82 are provided to interengage with the lugs 17 formed in the zone 10 at the other end of the strip.

The

openings

40 and 80 are equally spaced about the hole 56. The blank of FIG. 1 is readily folded and assembled by manual or mechanical means to form the carton seen in FIGS. 2 and 3 and in simplified form in FIG. 4.

As best seen in FIG. 4, the blank folds around the globe to form in effect a base in which the metallic base of the globe is supported, a skirt overlying the base, and a loop extending over the top of the globe. The various zones of the blank form, in the erected carton, a roof 24, substantially upright sidewalls 20 ad and 28, sloping

sidewalls

34 and 78 extending from the head of the bulb towards its waist, slightly off-

horizontal panels

36 and 74 embracing the waist of the bulb, lower or

skirt walls

50 and 70 extending downwards along the length of the metallic base of the globe, and apedestallike base 54 comprising the panels 59 and the panel 55, which latter panel is supported horizontally and through which the base of the globe protrudes. The ends of the strip are held together by interengagement of the lugs in the edge zone 10 with the semicircular holes in the zone 78.

The manner in which the ends of the looplike part of the carton, composed of the

zones

34,28,24,20 and 78, are held relatively to the base zone 54, is best seen in FIGS. 2 and 3. From these FIGS. it will be noticed that the base 54 and the various panels within it are so located that the panels 59 slope upwards from the lower ends of these the

skirt walls

50 and 70 to the horizontal, centrally located panel 55. The panels 61, on the other hand, slope upwards from the central panel 55, with the ears 58 bent obliquely to them and with the lugs 46 extending into the ears and thereby holding the waist of the canon firmly together. The panels 57 in effect form bevel surfaces between the

panels

59 and 61, and serve to stiffen the base of the carton and prevent displacement of the

panels

59 and 61 from the positions determined for them by the angular disposition of the score lines 64 and 66. The strip from which the carton is composed is under a slight tension which assists in keeping the various interengaging members firmly in place.

Effective support for the globe inv the carton is provided at several points. The uppermost is at the top of the globe, where the roof zone 24 bears on the head of the globe. The

sidewalls

28 and 28 bear on the central portion of the bulb at diametri cally opposite points, and the domed surface 42 of the openings 5 40 and 80 in the

sloping sidewalls

34 and 78 also support the bulb where itprojects through the openings. The scalloped edge 44 of the

openings

40 and 80 in the

panels

36 and 74 supports the waist of the bulb a short distance above the base of the globe. Finally, the metallic base of the globe rests in the hole 56 in the base 54. The globe is thus prevented from moving inside the carton, or from accidentally being removed from it, the positive efi'ort of disengaging the locking lugs 17 in the zone 10 from the holes 82 in the zone 78 being required before the globe can be withdrawn from the grip of the surfaces 44 and the hole 56 to free it from the carton.

Erection of the carton from the blank, and insertion of the globe into it, are simple matters that lend themselves readily to automation.

Although the invention has been described above in relation to an incandescent electric light globe, it is equally suitable for use in the packaging of other similar fragile objects.
