Patented Jan. 3 1 939 UNITED STATES CONTAINER AND FLANGED CLOSURE THEREFOR Herman Carew, Easton, Pa., assignor to Dixie- Vortex Company, Easton, Pa., a corporation of Delaware Application July 25, 1936, Serial No. 92,637

3 Claims. (Cl. 229-5.5)

' My invention relates to new and useful improvements in containers and flanged closures therefor and more particularly to a container and closure formed of paper of the desired thickness and weight, the principal object of the invention residing in the formation of a container and closure in such a manner that a flanged closure may be readily applied "to and held on the mouth portion of a container having a tapered wall portion.

. Another object of the invention consists in reinforcing the container around themouth portion and providing by said reinforcement a perpendicular wall portion adapted to be frictionally l5 engaged by the depending vertical flange of the closure.

A further object of the'invention resides in forming the closure of relatively thin material and turning a flange therefrom, a reinforcing ring being positioned interiorly of and securedto the flange and adapted to have frictional contact with the perpendicular wall portion of the container.

A still further object of the invention consists in forming the closures in a novel manner so that a plurality thereof may be stacked, they also being so formed as to permit expansion as to diameter when applying and contraction after application to permit snug engagement of the parts and such frictional engagement as will prevent accidental disengagement of the closure from the container.

With the above and other objects in view, which will appear as the description proceeds,

. my invention consists in the novel details of construction, and arrangement of parts, described'in the following specification and illustrated in the accompanying drawing, and while I have illustrated and described the preferred embodiments' of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In thedrawing:--

Fig. 1 is aside elevation, with parts broken away, showing a closure in position on a container.

Fig. 2 is a fragmental enlarged view showing a transverse vertical section through a portion of the container and closure thereon.

Fig. 3 is a transverse vertical section through ,a plurality of stacked closures.

Fig. 4 is a plan view, reduced, of a blank from which a closure is to be formed.

Fig. 5 is a plan View, reduced, of the blank able manner.

shown in Fig, 4 with the edge portions scored to permit ready bending to provide a flange and to permit corrugations being formed in the flange to take up excess material.

Fig. 6 is a plan view, reduced, of a reinforcing band adapted to encircle the mouth portion of a container; and I Fig. 7 is a plan view, reduced, of a reinforcing band adapted to be inserted interiorly of the closure flange and secured thereto.

In the drawing 41 indicates generally a container while b denotes generally a closure adapted to be applied over the mouth portion thereof.

The container a includes a tapered body or wall portion I and a bottom 2, the bottom 2 having 3 a depending flange 3 whereas the bottom edge of the body is turned upwardly as shown at 4 to engage the depending flange of the bottom. The body or wall i, as well as the bottom 2, is formed of paper of the desired thickness or weight and while I have shown the body as being formed of a singleply it will be appreciated that it might equally as well be formed of a multiplicity of plies such as by rolling a blank orin other suit- A reinforcing band 5 of heavy paper, cardboard or the like, is adapted to be positioned around the mouth portion of the body and secured thereto as shown more particularly in Figs. 1 and 2 of the drawing. This band 5 is of such a diameter that when it is pushed upconnection is formed between the band 5 and portion 6 than would be the case if an attempt was made to securethe band to a tapered wall. It will be noted particularly that the outer surface of the band 5 will be perpendicular for a purpose which will be later apparent.

The closure b, in the form of a cap is shaped or formed from a blank 0 indicated more particularly in Fig. 4 of the drawing and extending inwardly a distance from the marginal edge of this blank 0 are circumferentially spaced scores 1 which facilitate the bending of the blank to provide a flange to be later described and to take up the excess material caused by the forming of the flange. The closure or closure cap includes a top portion 8 and a depending flange 9, this flange 9 being folded from the blank c and when formed being corrugated as shown due to the folding of the excess material. A depression I8 is formed at the juncture of the top 8 with the flange 9 and forms a seat for the edge of a flange when a plurality of closures or caps are stacked as shown more particularly in Fig. 3 of the drawing. It will be understood that the seat or depression Ill extends around the outer edge of the top and is of such a circumference as to receive the bottom edge of the flange of a cap or closure positioned thereon in stack formation as shown more particularly in Fig. 3. When a plurality of the closures or caps are stacked the outer walls of the flanges will be in a perpendicular line. The tops 8 of the closures or caps are formed inwardly of the flanges with circumferentially extending depressions II which will allow for slight expansion of the caps or closures when being applied and which have a tendency to contract the caps or closures after application to snugly engage the closure with the container. A ring or band [2 of paper, cardboard or similar material, is secured to the inner wall of the flange 9 and the inner surface of this ring or band is adapted to frictionally engage the outer face of the ring or band secured to the mouth portion of the container. It will be seen that a relatively large frictional area is provided and the closure or cap will be held in position again accidental displacement although it may readily be applied or removed from the container when desired.

From the above detailed description it is thought that the construction of both the container and closure or cap will be clearly understood as well as the advantages thereof. In the past considerable difliculty has been experienced in applyin a flanged cap or closure to a tapered container but with my construction a perpendicular wall is provided at the mouth portion of the container and it provides a relatively large area for frictional engagement with (the closure or cap. At the same time the mouth portion of the container is reinforced as is also the depending flange of the closure or cap. The closures, as previously stated, are of such a formation whereby they may be readily stacked and by supplying a circumferentially extending groove in the top 8 of the closure or cap the diameter of the cap or closure may be slightly increased, or there may be a giving, so to speak, in applying the closure or cap to the container. However, when the cap or closure is applied the parts will tend to spring back to their normal position to secure a close frictional engagement between the bands or rings 5 and I2.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is:-

1. A closure for a container including a top portion and a depending flange, the top portion being formed with a circumferentially extending flat seat at its marginal edge adapted to receive the bottom edge of a flange of a succeeding closure of a stack, the seat being of a width corresponding to the thickness of the flange to pre-- vent lateral movement of one closure relative to the other.

2. A closure for a container including a top portion having an integral depending portion, and a reinforcing band secured to the inner face of the depending portion and cooperating therewith to form a flange, the top portion being depressed around its marginal edge to provide a flat seat of a width corresponding to the combined thickness of the dependingportion and associated reinforcing band and to receive the bottom edges of the formed flange of a succeeding closure of a stack to prevent lateral movement of one closure relative to the other.

3. The combination with a container including a tapered body portion and a band positioned around the mouth portion thereof, said band contracting the mouth portion to provide a vertical wall adapted to engage the inner surface of the band throughout its height and to form a smooth flat surface for securing the band to the container, of a closure for the container, said closure including a top portion, a depending flange, and a reinforcing band secured to the inner surface of the flange, the top portion being depressed around its marginal edge to provide a flat seat of a width corresponding to the combined thickness of the flange and reinforcing band and to receive the bottom edges of the flange and band of a succeed ing closure when the closures are arranged in a stack and to prevent lateral movement of one closure relative to the other, the reinforcing band secured to the inner face of the flange of the closure engaging the band positioned around the mouth portion of the container when the closure is in position on the containen'the band of the container and band of the closure forming a relatively large frictional area for holding the closure on the container against accidental displacement.
