7 Claims. (Cl. 229-23) j This invention relates to a novel-.carton and more particularly relates to cartons suitable for the safe packing and storing of cones and other yarn packages.

' In conventional cartons the height of the kcarton is iixed. 1n filling such a carton, unless the objects placed in the carton are exactly equal in height to the interior of the carton, there will be some free space withinkthe. carton. This free space within the carton increases the volume taken up by the carton during shipping or storage and, in addition, unless a space filling material is introduced into the carton the packed material is free vto move about with possible damage resulting therefrom. With conventional cartons having telescopic top and bottom memberslthere is the added shortcoming that when closed the rim of the wall of the inner members abuts the end of the outer member and if an external compressive wire, the wall of the inner member may buckle or mayV dig into the end of the outer member with damage to both members. c v

It is accordingly an object of this invention to provide a carton which can be reduced in size sufficient justA to accommodate the contents with no wasted vertical space. 4- A Another object of the invention is to provide ai novel carton which is constructed so as to minimize damage toits contents as well as to its component parts. y

Other objects of this invention will be apparent from the following detailed description and claims.

, According vto the present invention there is providedy a' carton comprising a pair of members each havingaand other tongues interiorly thereof so that telescopic,

displacement of the members toward each other is limited by the depth of the slots.

2,936,941 Patented May 17, 1960 The invention willrnow be described more fully withvr reference to theaccompanying drawing wherein:

force is applied, as during'4 stacking or banding with Fig. 1 is an exploded perspective view of the carton of this invention;

Fig. 2 is aperspective view of the assembled carton; and

Fig. 3 is a section taken along-line 3-3 of Fig. 2.

Referring now more particularly to the drawing, in Fig. 1 there is shown a top member 11 having a rectangular end 12 closed in conventional manner, asby staples 13. Two pairs of opposite rectangular walls 14,

15 are connected with respective sides of the closed end 12', defining an open end 16. A tear tape 17, to facilitate opening after sealing, runs about

walls

14, 15.

A bottom member 18 has a closed end 19 and two pairs of

opposite walls

20, 21 defining an open end 22.v

The lines of joinder between adjacent walls are slotted as at 23 for a part of the distance from open end 22 toy closed end 19, defining pairs of

opposite tongues

24, 25. The upper corners of the tongues are rounded o as at 2 6 to facilitate assembly.

After filling the bottom member 18 with the goods and continuing stacking the goods until the desired of bottom member 18 are resiliently bent toward each other and tongues 24 are bent away from each other. Side walls 15'of top member 11 are slipped overv tongues 25, the telescopic engagement being facilitated by rounded corners 26, 4while the side walls-14 are slipped inside` tongues 24. "The telescopic displacement will be limited either by the ygoods within the carton or'by the depth of slots 23. Because of this depth minor variations in the height of the goods can be vaccommodated without waste of space. The overlapping between the

tongues

24, 25 of the bottom member 18 and the

walls

14, 15 of the top member 11 serves as a reinforcement and also permits sealing Aby staples (not shown) driven through both. Conventional band sealing with wire (not shown) can also be used.

Because thewalls` of one memberV do not extend to the closed endof the other member, there is no possibil-v ity of buckling of the walls or damage to the ends.

With known cartons having at least a three-piece con'-A structin, viz., spaced top and bottom cover members extending toward each other about a liner, when raising one carton with a fork truck there is the possibility that the bottom'cover member of the carton being raisedl might hit the top cover member of an adjacent carton whichis notbeing raised and thereby ldamage Yboth cartons. This cannot occur with the present construction.

Because* of the division of the height of the carton intov two portions, the bottom member can be loaded or unloaded readily from above when the total height is In a preferred embodiment, the members have reo-- Y tongues. Such material also readily lends itself to sealv ing by stapling or banding with wire.

While the novel cartons are useful in packing of many materials, they are especially suited for packing yarn packages such as cones, bobbins, and the like.

such that a unitary cartonY could not be so handled. For,

example, a carton in accordance with the present invention might have a topmember 351/2 inches high and a bottom member 23,?/2 inches high With slots' 6 inches deep, giving a minimum assembled `height of 53 inches'. While'anoperator could readily bend over for access to the-"very bottom ofthe 231/2 inch bottom member, vhe. could not ,reach down into a carton where the access,

opening was 53 inches high. o

The novel carton is conveniently .used in conjunction with an open ended liner having a plurality of flaps, such as is described in copending U.S. patent application Serial No. 533,633 filed by Alvin B. Storey on September 12, 1955. The liner comprises a plurality of walls successively joined to each other to form a tubular structure open at its top and bottom. At least two, and preferably all, of the lines of joinder between adjacent walls of the liner are slotted downwardly along a portion of their height to form one or more flaps which can be folded down tjo .afford access to the interior, i.e. with a liner 53 inches high 7 an operator could not reach down into the liner for loadmany variations may be made therein without departing` from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:
