INVENTOR. Frank H. We By ggon r fi ATToRNEY Patented Sept. 30, 1952 Frank H. Waggoner, Ramsey, N. J

Application December 16, 1949, Serial No. 133,238

3 Claims.

My invention relates to an improvement in a Container Closure and the novelty consists in the adaptation and combination of parts as will be more fully hereinafter pointed out.

Millions of containers such as paper cereal boxes are made and used every month of the year, and because these boxes or containers are filled with food or other material that is not used up formany weeks after opening, there is a real problem to close and keep closed the tops of said containers, after they have once been opened, in order to keep the contents clean, fresh and dry.

My device solves this problem completely and eifectively without adding to the cost of the container.

Referring to the drawings- Fig. 1 is a plan view of the flat of my container with the bottom part broken away for convenience in illustration;

Fig. 2 is a perspective of my container in the original sealed position and with the lower portion broken away for convenience in illustration;

Fig. 3 is the same as Fig. 2 after the sealed top closure has been opened;

Fig. 4 is the same as Fig. 3 but with the top closure members locked in a closed position.

In the drawings, 5 and 6 are side wall portions of a card board box or container 1 which has end portions 8, 9, and [0. The side wall portion 5 has a top flap I l integral therewith which folds on the crease i2 and said flap II also has an outwardly curved locking cut [3 at each edge. Side wall portion 6 has a top flap I4 integral therewith which folds over the crease I! and end portion 9 has a 'fiap I8 integral therewith which folds on a crease Hi. There is also a crease 20 between side 5 and end 8 so that end 8 can fold at right angles toward side 5 to form the container 1. So also there are creases 2| and 22 so that ends 9 can fold at right angles to both side 5 and side 6 respectively. A crease 22 permits end portion [0 to be folded at right angles to side 6.

The lower portion of the flat of Fig. 1 is not shown and is a duplication of the upper portion of Fig. 1 except locking cuts [3 are omitted.

The regular closing and sealing of the container or box 1 at the top is shown in Fig. 2 in which flap I4, which has a gummed edge 24 on the lower side of edge 25 is stuck down to the flap ll, thereby forming a sealed complete closure with the flaps l6 and 18 being folded underneath.

This top is opened in the usual manner by running a knife along under the stuck down portion 24 of edge 25 of flap l4 and freeing it from flap II to which it is adhered.

Part of the cereal or other contents of the box 1 can then be poured out for use, and to close the top against deterioration of the balance of the contents and to keep moisture and dirt out. the top can be closed by slipping the edge of flap l4 into the two locking cuts 13 of flap H which is wider and extends under flap l4 thereby locking the top together, with the flaps l6 and I8 thereunder, so as to eifect a perfect closure of the container top. The curves of locking cuts l3 facilitate the engaging and disengaging of flap M with locking cuts [3 of flap H.

This perfect closure of the top of box 1 after it has been unsealed, as described, is a closure that can be constantly used to open easily and quickly by puttingv the finger on the edge 25 of the flap l4 and raising flap l4 thereby ensuring an opening means that can be repeatedly used without injuring the locking parts-flap l4 and the locking cuts [3 of flap ll.

Many variations may be made in my device without departing from the spirit and intent of the same and such variations are comprehended within the terms of the specification and claims herein.

What I claim is: l. A top closure for a container comprising two flexible overlapping flaps, one being wider than the other, the wide one being overlapped by the narrow flap, a sealing edge of said narrow flap being normally adhered to said wider flap, cuts in the overlapped portion of said wider flap each running from a point adjacent the edge of the narrow flap to each of the side edges of the wider flap and terminating at a point portion of said flap and curved away from the outer free edge of said flap at their inner ends which on the breaking of said sealed edge form locking elements for the engagement of each 3 end of said upper narrow flap to reestablish a the edges of the overlapping flap to form a separable closure.
