This invention is directed to a novel construction of shipping container or box, designed to be made from paper board using a single rectangular piece of paper board material with a minimum of waste in fashioning said rectangular material so that by folding it along predetermined lines it may be very quickly and readily made into a box or container adapted to hold merchandise and which can be closed for transporting the same from one place to another.
One primary object of the present invention is to provide a container of the class indicated, of a novel structure which, when itis shaped into its box-like form, is strongly reinforced against distortion out of shape and is also of particular strength in resisting any disconnection of the parts such as might come, for example, from the weight of the merchandise held within the container pressing against the bottom thereof.
The construction which best embodies my in-' I vention is disclosed in the following description taken in connection with the accompanying drawings, in which:
Fig. 1 is a perspective View of the completed container with the top partly open.
Fig. 2 is a plan'view of the blank made from a rectangular section of paper board stock which may be folded along predetermined lines to make the container shown in Fig. 1.
Fig. 3 is a fragmentary perspective view of the upper portion of one end of the closed boxor container.
Fig. 4 is also a perspective View of the container but showing a different form of closure means for one end thereof, and
Fig. 5 is a fragmentary perspective View of the container shown in Fig. 4, but showing the closure means in closed position.
Like reference characters refer to like parts in the different figures of the drawings.
As shown in Fig. 2 a single rectangular sheet of suitable paper board material is provided, longer than it is wide. This piece of material is scored longitudinally on parallel lines I and 2 which are parallel to the side edges of the sheet, and is further scored transversely on the lines indicated at 3, 4, 5 and 6. It is along these lines that the material will be bent or folded. The two sections 1 and 8, which will make the vertical sides of the box, are separated from each other by an end section 9 and at the end of one side section 8 is a similar end section II]. In each of the four corner portions of the vertical side sections I and 8 triangular shaped portions I I are out which remain connected with the sheet of material at the corners of said parts II as shown. Outwardly beyond the horizontal scorings I and 2 and connected with thevertical side sections I and 8 are the flaps l2 and I3 respectively, which are substantially one-half of the width of the receptacle to be made. Other flaps I4 are integrally connected with the end sections 9 and I0 having the same width as the flaps I3 and, as shown in Fig. 2, lying inalinement therewith.
At one end of the rectangular material sheet,
notches I5 are out leaving a narrow flap I6 integrally connected with the endsection I0 and foldable along the line 6. In the outer edge of the flap I6 two triangular notches H are cut for a purpose which will hereafter appear. Outwardly beyond thenotches at I5, and integral with the ends of the adjacent flaps I4, lock-tongues I3 are formed of the shape shown, each havin a notch I9 therein as shown. w
At the opposite ends of the flaps I 4 where they join the flaps I2 and I3 respectively, similar flaps I8 are made by cutting inwardly the notches 20, and cutting a line out as at 2| in the shape shown which joints at one end with the notches 20, is curved around and comes to the scoring lines 3, 4 and 5 and follows said lines inwardly until the scoring lines I and 2 are reached. The inner portions of the notches 20 provide similar notches I9 in the locking tongues I8 to the notches in the tongues 18 first described.
The flaps I4 may be turned at right angles to the sections 9 and I0 by bending on the scoring lines I and 2. The flaps I2 and I3 ma likewise be bent to right angles to the vertical sides I and 8 of the box. The sheet may also be bent upon the lines 3, 4 and 5 to form the sides and ends of the box, as shown in Fig. 1, the flaps I2 and I 3 turned inwardl toward each other and the flap I6 turned at right angles to lie inside the free end portion of the side section I and be stapled thereto, as in Fig. 1. The flaps I4 with the locking tongues I8 turned at right an gles thereto (Fig. 1), are then turned to lie over the ends of the flaps I2 and I3, the locking ues entering t r u h the openings provided by the cutting of the triangles at II, the free end portions of said locking tongues beyond the notches I9 passing to the innerside of the box, and the notches providing an interlock with the sides of the box as best shown in Fig. 3. This is done at both the top and bottom of the box. The notches at I! in the member I6 are made so as not to interfere with the triangular parts, ll
Such construction of box may be shipped in the flat as in Fig. 2 and the box very readily shaped by folding along the scoring lines, the bottom closed, the material which it is to hold placed therein and then the top closed. This box is particularly adapted for holding certain vegetables such as celery, celery cabbage and the like which should have access of air thereto, therefore the vertical sides of the box are shown with ventilating slots. These, however, form no part of the invention and the box 0r container is not limited in use for holding any one thing.
The locking tongues l3 embracing the outer sides of the box reinforce it at its corner portions and serve to help maintain it against any distortion out of shape. The locking provided by the notches at 19 reinforce both the top and bottom of the box, either one of which may become the bottom of the box and have to sustain the weight of whatever is inside thereof, and provide a strong resistance against any disconnection of said tongues from the openings through which they pass. It is evident that very little of material is cut from the rectangular sheet shown in Fig. 2 so that the waste is reduced to a minimum. The construction is very practical and useful.
Having particular reference now to Figs. 4 and 5 wherein a diiferent form of closure means is disclosed, it should be here noted that this construction may be applied either to the top or bottom side of the container or to both. For the purposes of this disclosure, however, the structure will be described with reference to the top only.
As shown, the container itself is provided with the ends 9 and the bottom flap 18 as shown in Fig. l, the side members are indicated by the numeral 8a inasmuch as the upper ends thereof are not provided with the openings ll. Connected to each end 9 are the end flaps 22 which are provided with the cut away portions or slots of the configuration shown at 23. Each side member 8a is provided at its upper ends with the integral side flaps 2 5. One flap, extends outwardly from the scored line I and the other extends from the scored line 2. Each end of the flap 24 is notched as at 25 which notch extendsdownwardly from the end of one flap to the scored line I and on the other flap down to the scored line 2. These notches provide the ears 26 at each end of the end flaps 24 and extend outwardly therefrom.
When these various flaps are in closed position they appearsubstantially as shown in Fig. 5. The end flaps 22 are folded inwardly first and then the side flaps 24 are folded on top thereof and the ears 2B which are on the same end of the opposing side fiaps 24 are inserted in the common slot 23 to thereby lock the various flaps in closed position. It will be obvious that this form of the invention may also be cut from a single length of material as described above with respect to Figs. 1 and 2 but changing the various flaps as disclosed in Fig. l. The various advantages arising from this form of the invention will be similar to those described above with respect to the first form insofar as lessening the waste material is concerned.
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within theirv scope.
