1 Claim.

My invention relates to knock-down hat boxes or other containers and it has for its object to provide an improved box of that type which consists of a single piece or blank of paperboard or the like that is formed with fold-defining score lines and with interlocking flaps by which the folded blank is held in the form of a box without the use of adhesive or other fastening means.

To this end I have provided a hat box or the like of the class referred to which, in its best form, may be constructed as set forth in the following description, the novel features of the invention being particularly pointed out and defined in the claim at the close thereof.

In the accompanying drawing:

Figure 1 is a plan view of the blank from which my improved box is made.

Figure 2 is a perspective view showing the box partly made.

Figure 3 is a perspective view showing the box completed.

Figure 4 is a cross-sectional view showing one method of interlocking the handle flaps, hereinafter referred to.

Figure 5 is a cross-sectional View showing another method of interlocking the handle flaps.

The blank shown in Fig. 1 is made from paperboard or the like and comprises an elongate body portion consisting of a straight row of four rectangular side wall sections or panels I, 2, 3 and 4, and an end flap section 5. The body portion is formed with relatively parallel transverse folddefining score lines 6 and with relatively parallel longitudinal fold-defining score lines 611.

Along one side thereof the body portion of the blank is made with four top wall tang flaps I, 8, 9 and I0, one on each side wall section, and along the opposite side thereof the body portion of the blank is made with four rectangular, or approximately rectangular, bottom wall flaps I I, I2, I3

and I4, one on each side wall section.

The end flap section 5 of the body portion of the blank is slitted as at I5 and shaped to provide a hook I8 adapted to be inserted in a slit IT formed in side wall section I thereby to interlock the opposite ends of the body portion of the blank as shown in Figs. 2 and 3.

The tang flap 1 tapers toward its free end and is formed at its outer end with a hook I8 adapted to be inserted in a slit I9 formed in the flap 9 of side wall section 3 as shown in Fig. 2, said flap 9 also tapering toward its free end as shown.

The tang flap I0 tapers toward its free end and at its outer extremity is formed with a hook 20 adapted to occupy either 'of two slits 2| and 22 formed transversely in tang flap 8 of wall section 2 as-shown in Figs. 3, 4 and 5, thereby to interlock the ends of said two tang flaps.

The two flaps I and 9 are made tapering as shown so that while they are being interlocked 5 the fingers of one hand may be inserted into the box to hold and support the tang flap 9 while threading the hook IB through the slit I9, as will be clear from Fig. 2. On the other hand the tang flaps 3 and I0 are made tapering as shown 10 and described so that when interlocked with hook 20 occupying slit 22 as shown in Figs. 3 and 4, said two interlocked tangs will provide a conveniently narrow upwardly arched handle by means of which the box can be carried. 15

When the hook 20 of tang flap I0 occupies the inner slit 2| of tang flap 8 as shown in Fig. 5 the two flaps, together with the interlocked flaps I and 9 provide the box with a flat top wall and this adjustment of the parts is resorted to when the 20 box is to be shipped or wrapped up.

The bottom wall flap I3 is made at its outer end with an extension 26 formed with two hooks 21 adapted to occupy slits 28 formed in side wall section I, as shown in Figs. 2 and 3. A fold-de- 25 fining score line 6b permits the extension 26 to be folded into a position at'right angles with relation to bottom flap I3. Q

The operation of forming the box from the blank of Fig. l is as follows:"I'he body portion 3 of the blank is bent sharply on the score lines 6 so as to bring the opposite ends thereof together with the flap 5 overlying the section I. Then, after inserting hook I6 of flap 5 in slit I! of body section I the two bottom flaps I2 and I4 are fold-, 5 ed inwardly on score line So, one on top of the other, after which the flaps II and I3 are folded inwardly on score line 6a in the order named and locked by insertion of the hooks 27 in the slits 28. Then the tang flaps 9 and I are folded inwardly 40 on the upper score line 6a in the order named and interlocked by insertion of hook I 8 in slit I9, after which the tang flaps 8 and ID are folded or bent inwardly on said upper score line in the order named and interlocked by insertion of hook 20 in 4 slit 22 when a handle is desired or in slit 2I when a fiat top wall is desired.

Adjacent to each hook I6, I8 and 20 the blank I is preferably formed with a relatively small tab 25 which may be bent outwardly and gripped by 5 the fingers of the hand that is employed to thread the hook into and out of its slit. Each tab 25 is disposed back of its hook sufliciently to avoid in-' terference with the edge of the slit.

The above described box or carton is of simple 55 and inexpensive construction and the only means required for holding the blank in its box-like form are five simple hooks which are operated alike.

What I claim is:

A rectangular box made from sheet material and comprising a bottom wall and four vertical side walls each made at its top with a flap and said flaps jointly providinga complete top 010- sure for the box when theyj are all folded inwardly so that they are disposed in superposed fiatwise relationship, means for separably fastening together the extremities of one pair of oppositely disposed flaps to hold the same fiatwise together and means for separably fastening together the extremities of the other pair of oppositely disposed flaps outside or said first mentioned pair, said last mentioned fastening means comprising a hook adjacent to the free end of one of the flaps of said other pair and two parallel transverse slits formed in the other flap of said other pair adjacent to the free end thereof with one of which slits said hook is engageable to fasten said other pair of flaps together in upwardly arched condition to serve as a handle and with the other of which slits said hook is engageable to fasten said flaps together fiatwise to provide said complete closure, and said other pair of flaps being made tapering toward their free ends so that they can be surrounded by the fingers of a hand while connected to form a handle.
