Description
March 1967 w. D- ANGSTADT REINFORCED CONTAINER RIM Filed Dec. 27, 1965 INVENTOR. BY William DQngsz ad L ATTORNEY United States Patent 3,307,766 REINFORCED CONTAINER RIM William D. Augstadt, Norristown, Pa., assignor to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Dec. 27, 1965, Ser. No. 516,486 4 Claims. (Cl. 229-45) This invention relates to a reinforced container rim, particularly for the open end of containers such as are used for textile rovings, and has for an object the provision of improvements in this art.
Containers, such as roving cans, are subject to very rough usage but are, nevertheless, expected to have a very long service life. They are commonly made of vulcanized fiber and conventionally have been made with a simple integral curled rim which is formed by common roll-spinning devices which roll the top edge out toward the outer side of the container side wall. Usually such containers have a closed bottom wall but if the object should be tubular and require edge reinforcement at one or both ends the present improvement would be applicable thereto as well as to bottomed containers having only one open end.
It has been found that simple integral rolled rims do not provide as much strength, fieXure-resistance, and durability as are desired and there have been many proposals for reinforcing the rim in various ways.
The present invention has for an object the provision of an improved rim reinforcement which is simple and easily formed.
Another object is to provide a rim reinforcement whic requires no turning of the rim of the container itself.
Another object is to provide a rim reinforcement which covers the upper edge and adjacent sidewall of the container.
Another object is to provide a very strong rim reinforcement of very light weight.
Another object is to produce a very strong, light reinforcement for a rim which does not greatly increase the overall diameter of the container at the open end.
The above and other objects of the invention, as well as various features of novelty and advantages, will be apparent from the following description of certain exemplary embodiments, reference being made to the accompanying drawings, wherein:
FIG. 1 is a partial axial section of the top edge of a container having a reinforced rim embodying the invention;
FIG. 2 is a similar view of a modified embodiment.
As shown in FIG. 1, a container 10, such as a roving can with a bottom closure (not shoWn)-and an open top edge 11 terminates as a straight single thickness of material.
This upper edge is provided with a reinforcing band or ring which is generally designated by the numeral 12. This band 12 has a relatively wide intermediate portion 13, an upper curled or rolled portion 14 which covers and tightly grips the upper edge of the container, and a lower reversely curled or rolled portion 15 which is disposed to lie closely against the outside of the container. It is shown to be located on the outer side so as to leave the inner side substantially unobstructed but for some uses the main body of the reinforcement might be disposed inside the container.
In the form shown in FIG. 1 the reinforcement is ICC formed of two similarly shaped parts or pieces 17 and 18 which overlap in the body portion for greater strength and which may be secured together at circumferentially spaced points in a suitable Way, as by spot welds 19. The upper rolled portion 14 of the part 17 is preferably squeezed tightly upon the upper edge of the container and the lower rolled portion 15 of the part 18 is squeezedtightly on the lower edge of the part 17. This may be adequate for many purposes without the welds 19; although the medial interconnection may be desirable to provide a single composite unit for easy handling.
The reinforcing band is preferably secured by suitable means, such as the rivets 20, to the sidewall of the container. In some cases such rivets may not be needed, particularly if the free edge of the upper rolled portion is squeezed sufliciently tightly upon the container sidewall, with crimping if desired to cause the metal to bite more deeply into the material of the sidewall.
In FIG. 2 a form is shown in whicht the band 12' is formed of a single piece of material with an intermediate body portion 13 and oppositely turned rolled edges 14' and 15, the former 14' embracing and gripping the upper edge of the container and the latter 15' lying alongside the side (again the outer side, as shown) of the container sidewall. Rivets could be used as before, if desired, to supplement the gripping action of the rim-embracing upper rolled portion 14' but, as another form of attaching means, circumferentially spaced crimped e1ements 20' are employed instead, the single thickness of the body portion 13' readily being punched inwardly with the material of the sidewall of the container by tools of known form.
The present rim in either form, with oppositely directed hollow-section elements on the spaced edges of a medial band body is several times as strong and much more rigid than rims which are formed by turning the material of the container edge upon itself. The metal may be selected to have considerable springiness whereby to resume its shape after being squeezed.
Further, the upper edge of the container is covered and protected by a turned metal element, the element in the rolled shape shown also providing a neat appearance and avoiding passing it in filling or emptying the container.
While certain embodiments of the invention have been described for purposes of illustration, it is to be understood that there may be various embodiments and modifications within the general scope of the invention.
I claim:
1. A reinforced container rim comprising a reinforcing band having separate pieces with overlapping medial strip body portions, one of said portions having a hollowsection element with a turned edge embracing and gripping the upper edge of the container and the other of said portions lying alongside the outer wall surface of said container and having a hollow-section element with a turned edge gripping the free edge of the body portion of the other piece.
2. A reinforced rim as set forth in claim 1, wherein means are provided for securing the body portions of said pieces together at circumferentially spaced points.
3. A reinforced rim as set forth in claim 2, wherein said securing means comprises spot welds in the body portions of said pieces.
4. A reinforced rim as set forth in claim 2, wherein said securing means comprises means which also secures body portion.
