7 Claims. ((1229-35) This invention relates to improvements in telescoping boxes or cartons having interlocking wall elements. I
The main objectsof this invention are:
First, to provide covered boxes or cartons in which the body member and the cover are each formed of an integral blank which can be readily set up either by hand or by machine.
Second, to provide a covered box or carton in which one opposed pair of cover wall elements are provided with corner flaps, the other having slits receiving locking tongues on the corner flaps and in which the parts are so conformed and associated as to permit engagement of the cover with the body without displacing the interlocking parts of the cover.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:
Fig. 1 is a perspective view of the body and cover of my improved box or carton in separated relation.
Fig. 2 is a transverse section of the completely closed box somewhat enlarged as compared to Fig. 1. I
Fig. 3 is a transverse section corresponding to that of Fig. 2 with the cover partially closed.
Fig. 4 is a fragmentary inside perspective view of one corner of the box showing the relation of the cover and body parts during the initial closing movement of the cover.
Fig. 5 is a fragmentary perspective view corresponding to that of Fig. 4 with the cover' moved further to closing position and illustrating the camming. action on the locking flap which prevents engagement therewith with the body of the box.
Fig. 6 is an enlarged fragmentary view on a line corresponding to line 66 of Fig. 3.
Fig. 7 is a plan view of the, blank of the body member.
Fig. 8 is a plan view of the blank of the top member.
In the embodiment of my invention illustrated the box body member is formed of an integral blank suitably scored and slit to provide a bottom I, side walls 2 2 and end walls 33, the blank being scored to provide hinging connections for the side and end walls to the bottom. The end walls are provided with comer flaps 4 having upwardly projecting tongues 5 engageable with the portions of the side walls above the slits 6 in the side walls which extend diagonally upward and open at the end edges of the side walls as is clearly shown in the blank of Fig. 5.
When the box is erected the lower edges of the corner flaps are inserted through the slits and the tongues engaged with the upper edges thereof or the portions lot the walls above the slits. This effectively supports the walls in erected position with the bottom edges 8 of the flaps resting upon the bottom I as is shown in Fig. 2.
The cover also formed of a cut and scored blank comprises a top 9, side walls Ill and end walls H. The side walls are provided with corner flaps l2 having downwardly projecting tongues 13. The
end walls are provided with diagonally disposed slits l4 opening to their end edges and adapted to receive the corner flaps with the top edges of the corner flaps engaging the inner side of the top. The tongues on the corner flaps l2 engage the portions ii of the end wallsbelow the slits l4 and it will be noted that they are on the inner sides of the end walls and project inwardly somewhat. The cover is of such dimensions as to telescope over the body ot-the box and is desirably a relatively close fit.
To prevent the portions of the corner flaps of the top, which project within the end walls of the top, from engaging the end walls of the bottom and thereby displacing the corner flaps or preventing the closing of the box, the end walls of the box are provided with notches l6- suitably spaced to receive the inwardly projecting tongue port-ions l3 of the corner flaps during the initial closing movement of the box as is illustrated in Figs. 3 and 4. The recesses are conformed to provide camming edges IGI, which engage the inwardly projecting parts of the corner flaps as the cover is further moved or adjusted to closed position as shown in Fig. 5 deflecting these parts l3 outwardly so that the cover may be completely closed without engagement of the corner flaps or otherwise displacing or injuring the interlocking parts. This greatly facilitates the closing of the box and without likelihood of displacing the corner flaps or disengaging the interlocking parts of the box. With the box body thus arranged the side walls of the top close over the corner flaps without engagement therewith.
I have illustrated and described one form of interlock for the walls of the box and cover but it will be understood that there are other forms of interlock in which the locking tongues project interiorly of the walls and therefore my claims are not conformed to the particular form of interlock which is illustrated and described.
Both the cover and the body are desirably formed of integral blanks 9 shown in Figs. 5 and 6 and may be easily and quickly set up either by hand or by machinery. This permits the box parts being shipped in the knockdown and set up by the user and the cover assembled with the body without likelihood of the interlocking parts becoming disengaged or the walls distorted. My invention is well adapted for use in a covered box or carton in which the walls of the body are glued or otherwise secured in erected position.
I have used the terms side walls and end walls for convenience in description but it will be understood that the box may be a square box where desired and the terms side and end walls would be arbitrarily applied.
I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe other embodiments or adaptations as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as. may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
