JAMES BROWNLIE, F DENNISTOUN, GLASGOW, AND ARCHIBALD HORSLEY, 0F THORNLIEIBANK, GLASGOW, SCOTLAND COLLAPSIBLE BOX 0R CASE FOR HOLDING ELECTRIC AND OTHER BULBS Application filed May 7, 1928, Serial No. 275,815, and in Great Britain December 10,1927.

Our invention relates to improvements in and connected with collapsible boxes or cases for holding electric and other bulbs, and is an improvement in or modification of our earlier application No. 233,281, of 14th November,

1927, and has for its object inter alia to reduce the cost and simplify the packing of such and atthe same time enable the bulb to be tested without removing it from the case or box.

In carrying out this invention under one form of construction, the box or case is made of one-piece of cardboard or other suitable material and is so scored as to form the four sides of the box or case, one of the sides being provided with a slit and that on the side at the opposite end is of rounded formation to easily slip into the slit when the box is made up and binds the whole together. The cardboard is further out and scored at the lower end to form the bottom and top of the box or case and the carrier for the bulb. In this carrier a shelf is formed, having a circular hole for the reception of the neck of the bulb and a circular hole is also formed on the bottom or base of the box or case by which it can be seen, when tested, whether the bulb is perfect or defective. A tongue-piece is formed on the lower part of the walls of the carrier with a double elastic band on and between which the bottom part of the bulb rests, the tonguepiece pressing against the bulb thereby retains it in position having sufficient resiliency or spring to prevent any damage to the bulb while in the box or case. A small tongue is also formed on the upper end of one of the walls of the carrier by which the loose end of the side of the shelf becomes locked in position. When the sides are folded over to form the box or case, the whole becomes one complete and perfect unit and ver readily collapsed for the removal of the bulb.

In place of having the rubber band, a shelf of cardboard or such like material may be provided and which is suitably stitched to the box or case, but otherwise it is in every way similar to that already described. When it is desired to test the bulb, the top or cover is opened on its hinge and the metal part exposed.

ber band 0, we provide a shelf S of cardboard In order that our invention may be properly understood and; readily carried into effect, we have hereunto appended one sheet of drawings, of which Figure l is a side perspective view of the box or case partially open and containing a lamp.

Figure 2 is an end perspective view of box or case slightly opened.

Figure 3 is a plan of complete sheet of which the box or case is formed on reduced sea a.

Figure 4 is a sectional elevation of a slightly modified form of box or case.

Referring to the drawings, A, B, C and D are the four sides of the box or case formed by scoring, as shown in dot "and dash lines, Figure 3, the side D having the slit E cut thereon, and F is the flap on the side A which is of rounded formation and fits into the slit E in the side D when the box or case is built up, thus, as stated, binding the whole together. G is the bottom or end of the box or case formed by scoring and is provided with a circular hole G by which it can be observed 75 whether the bulb is perfect, and H is the top formed by scoring. I is the shelf which is likewise formed by scoring and has also a circularhole I for the reception of the neck J of the bulb K. L and M are the walls of the carrier formed by cutting the cardboard or other material, each having a tongue piece N and N respectively cut thereon to which there is attached the rubber band 0. A tongue P is also provided on the wall M adjacent the top H thereby locking the loose end Q, of the shelf I in position. R is the top flap of the end of the box or case.

Referring to Figure 4 in place of the rubor such like which is stitched or otherwise attached to the box or case and is also provided with a hole S for inspection purposes.

Claims:

1. A collapsible box formed from a single blank and comprising four outer or covering wall members A, B, C, D initially arranged in a series side by side, an end member G united to one of said first named members, inner wall members L, M on opposite sides and united to said end member and closure flaps H, I at the outer ends of said inner wall members.

2. A collapsible box as claimed in claim 1, including also a flap F at the outer side of one of the outermost outer wall members and arranged to engage in a slot E in the other outermost outer wall member.

In witness whereof we affix our signatures.

JAMES BROWNLIE.
