CARTON Application filed November 19, 1928.

a My invention relates to cartons such as, for instance, those used as containers for foods for candies, bakery goods, suit boxes, laundry boxes, etc., and has for its general object to provide a carton having a novel means for securing the lid to the body of the carton.

More specifically, my invention provides a carton having a lid and a flap at the free end of the lid, the flap being adapted to overlap the front wall of the carton and the securing means being formed as part of the flap. In orderto obtain cheapness and simplicity of construction, which is also an object of my invention, a securing means is formed as a tongue struck out of the flap just mentioned and adapted to enter an opening or slot in the front wall of the carton.

My invention further contemplates providing means for guiding the tongue into the slot 90 which receives it and for engaging and holding the tongue in the slot so as to securely lock the lid of the carton against accidental displacement.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings,

in which:

Fig. 1 is a perspective View of one form of my invention.

Fig. 2 is a. transverse, sectional view of the same.

Fig. 8 is a transverse, sectional view of a slightly modified form of the invention.

Fig. 4 is a longitudinal, sectional view through the securing device and adjacent portions of the carton.

Fig. 5 is a front elevation of a modified form of the invention.

Fig. 6 is a transverse, sectional View of the same.

In the accompanying drawings, I have used the reference character 10 to indicate the bottom of a carton of common construction, the front wall 11 and walls 12, rear wall 13 and hinge lid 14 being all formed integrally of the same blank of material, cut to the proper Serial No. 320,329.

shape and fitted together to form the complete carton illustrated.

Inasmuch as my invention does not reside in the construction of the carton proper, with the exception of the front wall, which will later be more specifically referred to, the details of construction of the carton are not disclosed.

The carton shown is an ordinary paper carton, constructed of rather heavy stiii' paper but might be made of any material having the necessary qualifications of stiffness, strength and foldability.

The flap 15, which is bent downwardly from the lid 14, is a feature common to many old types of cartons but in my invention the flap furnishes a means from which the securing device or devices are formed.

These securing devices in the preferred form of my invention shown in Fig. 1 are formed by cutting U shaped slots 16 in the flap 15, thereby striking out the tongues 17.

The tongues 17 are designed to pass through an opening 18 in the front wall 11 of the box, which opening is ofvsuiiicient depth to receive the tongues and somewhat wider than the solid section of flap 15, which separates the tongues 17 It may be understood in this connection that although a single opening 18 is shown extending the full width of the distance between the flaps 17, a pair of vertical slits or narrow openings might be employed, positioned approximately the same distance apart as the extremities of the opening 18 and separated by a solid web of material.

The tongues 17 extend away from each other so that when inserted in the opening 18, they will be received behind the portions of the wall 11 bordering the sides of the opening 18.

In order to retain the tongues 17 so that some force will be necessary to remove them, I provide a secondary wall construction, lying immediately behind the wall 11 and completely covering the opening 18. This wall in the form of my invention shown in Figs. 1 and 2 is formed by bending the wall 11 inwardly and folding it downwardly against the wall 11 to form the inner wall 19 whichmay be secured at its lower edge by 7 means of a flange 20, secured under fingers 21, struck up from the bottom 10. The inner wall 19 lies substantially in contact with the wall-11 but'not connected therewith, thereby leaving a space to receive the tongues 17 between two walls; I

. The frictional 'engagenient of the tongues 17 between the'wall l9 and the wall 11' will 7 securely hold the tongues against accidental removal. p

The wall 19 further serves to guide the tongues 17 into place during insertion .of the tongues through the opening 18., 1 This is a;

very importantfeature of my invention for the reason that the tune necessaryfor secur ing the l d to the body of thecarton 1s ma teri'allyreduced with the aid of the wall 19. 1

Itis only necessary to bend the tipsof the tongues 17- toward each other until they will I enter the opening '18, to then allow them to spring apart, engaging the side extremities of the opening and the wall 19 and'then to press inwardly against the web of material separatingthe tongues, which latteraction will force'the tongues apart into the space between the walls19-and 11. This action maybe accomplished very rapidly and as quickly l as the webof material between the tongues has been forced flat against the wall 11, the carton lwill' be properly closedand locked. s i

I It will be readily, seen that itis not essential that the opening 18 be (placed in the wall of the carton if the portion which is continued upwardly from the bottom 10 is considered asthewall proper of the carton. The opening might be formed in a flap bent outwardly from the front wall of the carton and downwardly against the front wall. Such a construction is shown inFig. 3, in

' which the front wall of'the carton is referred to by the reference character 22 and the out wardly bent flap by the reference character I entirely to'th e bottom of the box 10." The chief requirement for these flaps is that they be folded over and retained in closely spaced relation to the front 7 wall of the carton. This may beattained either by use of the tongues 21 or 24 by gluing or pasting, by the engagement of other parts of the carton or, in some instances, merely byfolding. i I For: the purpose of describing this construction in my claims, the front wall and the adjacentflap may be considered as a double wall construction comprising two walls lying closely adjacent each other. I The walls back preferable method of forming this double 2 wall construction is by bendingone 0f the upon itself to form the second wall. Instead of arranging the tongues 17 horizontally, a single tongue may be'employed as s shown in Figs. 5 and 6, arranged in-a perpendicular position. In these figures, the

p The tongue 27 is struck fronithe flap V p in the same manner the tongues 17 and is united with the fiap at its lower extremity. The tongue 2'? is adapted to enter a slot 28 inlt-he wall 23 and is guidedinto place byv the inner wall 22in the same-manner as in the form of the invention shown in Fig. 3'. a

It maybe noted that after the tonguelv27-is in place any upward pullingagainst the flap'26"will tend to hook the tongue tighter into the opening 28. As in the preceding forms of the invention, the frictional en]- gagenient of thetongue between the walls It may also be noted that the doublewall 22 and 23 will also aidin tightly securing it in locking engagement with the carton.
