8 Claims.

/This invention relates to a new and improved container, and has for its object the provision of a container that is strong, light in weight, inexpensive to manufacture and simple to use.

The novel features that characterize the present invention are set forth with particularity in the appended claims. The. invention itself, however, will be understood best by reference to the following specification when considered in con- I nection with the accompanying drawings, in

which:

Figure l is a longitudinal section through a container body involving one embodiment of the present invention;

Figure 9 is afragmentary view, in section, of ai.

portion of a container involving the use of a detent in the form of a band in placeof the detents or lugs shown in Figure 2;

Figure 10 is a fragmentary view, in. section, of a portion of a container involving the use of a dentate band or detent in place of the individual o detents or lugs shown in Figure 2;

Figure 11 is a fragmentary view, in section, of a portion ofa container showinganother modification of the type of container shownin Figure 3.

The container body shown in Figure 1 comprises a shell I, open at the ends, and 'a'reinforcing band 2 at each end vthereof that tightly embraces the said shell. As shown, the shell I has depressions 3 formed at intervals in the outer surface of the shell and extending in a peripheral 50 direction. Registering with and engaging the depressions 3 in theshell I are shown deformations 4 in the bands 2 encircling the shell.

In Figure 2 the complete container is shown comprising a shell I with reinforcing bands 2 u tightly embracing the shell I at the ends there-A of; a top closure plate II, a chime strip I2 in position against said closure plate II, and the bent-over ends of detents I3 engaging the chime strip I2 and holding it in place. Although not so shown in Figure 2, the detents I3 pass between 5 the shell I and the reinforcing bands 2, and are held against longitudinal movement with respect t`o` the shell I by their engagement with the opposite side of the peripheral deformation I5 in the band 2. Y

A better understanding of the structure shown in Figure 2 may be had by'reference to Figure 3, which shows a portion of the container in section. In this figure, the shell I is shown with a peripheral depression 2I in its outer surface and a cor- 15 responding bulge 22 on its inner surface. The top closure plate I I is shown resting on the bulge 22 and held in place by the chime strip I2. In this figure, the detent I3 is straight at its upper end and not bent over to engage the chime strip 20 l2 as shown in Figure 2. The detent I3 is shown positioned between the shell I and thereinforcing band 2, and extending upward beyond the band 2 and bent over at the lower end of the band. 25

Thedetent I3 is further illustrated in Figure 4 and Figure 5. As shown there, it comprises a strip of relatively thin bendable metal having the shape shown in Figure 3. It has a perforation 3I located near the top to receive a tool, such as 30 a screw-driver, to assist in lifting up the detent after it has been bent over to hold the lid cr closure member in place.v It comprises also a plurality of tongues 32 punched out of metal to penetrate the shell I and serve as means for position- 35 ing it on the body or shell of the container prior to the application thereto of the reinforcing band l2 shown in Figure 1, Figure 2 and Figure 3, and

a bent-over foot 33 to engag the reinforcing band 2 and serve as additional means for preo venting longitudinalmovement of the detent with respect to the shell. The groove 34 engages with.

the depression 2| inthe shell I'and serves to prevent the detent from moving longitudinally with respect to the shell. u The detent 40 shown in Figure 6 is the same as that shown Ain Figure 4 and Figure 5 excepting' that it is provided at its upper end with a plurality of slits 4I for a purpose brought out later in this specification, and thatthe perforation 3| 50 of Figure 4 is omitted. The slits 4I divide the upper portion of the detent 40 into a plurality of strips 42, 43 and 44. i

In Figure 7, which shows a fragmentary view in section of a portion of a container of,the presu 45 1 out departing from the scope of the present inent invention, and of the same character as that shown in Figure 3, the detent t0 is the kind illustrated in Figure 6, and has a strip 42 bent over and vdown on the outside of the container, and

a strip 43 bent over and down to enga-ge the chime v stripI I2. The strip M of Figure 6 is behind the strip 42, in Figure '7, and therefore cannot be seen. f i

The modification shown in Figure 8 is the same as that shown in Figure 3, excepting that the Wooden closure member I I of Figure 3 is replaced by a pressed metal closure member 50. In this figure the detent I3 is shown turned down against the closure member 50,

Another modification of the present invention is illustrated in Figure 9. Here the detent 6D is shown partially turned down against the chime strip I2 and partially straight. The detent 60 is in the form of a band of thin bendable metal, the length of the band being approximately the same as 'the outer circumference of the shell I.

The detent I0 of Figure 10 is a modification of the detent 60 shown in Figure 9, in that the detent 'I0 is dentated to form individual lugs or detents 'II and 'I2 instead' of being continuous as shown in Figure 9. 'Ihe detents or lugs 'H are shown upright while the detents or lugs I2 are Ushown bent down to engage the chime strip I2.

'I'he modification of the container of the present inventionillustrated in Figure 11 is of the same character as that illustrated in Figure V3 excepting that the reinforcing band 80 of Figure 11 is held against longitudinal movement with respect to the shell I by means of staples 8l or other well known fastening means.

Throughout the above the'description of th mechanical features of various modifications of the container of the present invention, the term detent has been used in reference to bendable means located between the shell anclthe reinforcing band for fastening the end closure means or head in place. Inasmuch as the head fastening means herein illustrated and described and referred to as` detents are not the only modifications of such means that can be utilized with- One method by which containers of the pres-v ent invention can be made is as follows. Thev Shen l is mst formed by ughuy winding a. continuous strip of paper onto a mandrel of suitable size until a shell of the desired thickness is obtained. At`least the beginning portion and the end portion ofthe paper should be attached tothe surfaces of the paperv contiguous thereto by;

a suitable adhesive, such as glue, and usually the entire strip is coated `on one side with glue as it is being. Wound on the mandrel. By this method a substantially seamless shell ismade.

`be adhesively attached to'the shell I because the tight winding of the reinforcing` bandsonto the shell, and the interlocking of the reinforcing bands with the shell by means of the peripherally extending depressions 3 formed in the shell and the Yperipherally extending deformations 4 detent of the kind illustrated in Figure 9 or in .Figure 10 or is vto be equipped with detents of the kinds illustrated in Figure 2, Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, Figure 8 or Figure 11, the blanks for the particular type of detent or detents to be used are positioned on the cylinder I before the bands 2 are wound thereon. The detents illustrated in the various drawings are shown to be provided with punched-out tongues 32, and these can be utilized in positioning the detents on the shell I prior to the winding thereon ofthe bands 2 by driving them into the shell I. With the chosen detent or detents positioned on the shell I the reinforcing bands are Wound onto the shell I in the manner described above. 'Ihen the depressions in the shell and the deformations in the reinforcing bands are formed to interlock the bands with the shell. y

In the modifications shown in theJ drawings, with the exception of Figure 1, the deformation I5 is shown to encircle the band. Likewise the depression 2| in the shell encircles that member. These respectively.interlocking depressions and deformations are formed at the same time, while the paper of the shell and of the bands are still pliable, by mounting the shell on a suitable mandrel having located therein a groove of the proper size andshape to produce Athe desired size and shape of depression in the shell and applying pressure to the band, directly'over the groove in the mandrel, by means of a suitable tool while the mandrel, the shell andthe band are rotated. 'I'he pressure applied to the reinforcing band in the manner just described causes the shell, which is in a pliable condition, the detent and the reinforcing band, which also is pliable, to become permanently interlocked so that neither the detent nor the band can move longitudinally with respect -to the shell. As a matter of fact, the method herein described causes the shell, the detent and the band to be so united that, to all intents 'and' purposes, they form a unitary structure.

' 'Ihe term blanks was used in the foregoing .paragraph in connection with the particular type gof detent to be used in making a container of the present invention. This term was 'usedto indicate that the part that is-positioned on the shell prior to the application of the reinforcing ring is. v not, when the foregoing methodI of fabrication is employed, in the form illustrated in the various drawings because it does not have the groove 34 formed therein until the shelljthe detent and the reinforcing band have been .interlockgi bythe application of pressure as described It should be understood 'that the foregoing c70 method of fabrication is intended to be byway of illustration because various modifications of the method can be employed without departing from the scope of the'invention. For example,

the depression 2| in the shell can be formed prior 75 i v were made, other materials or combinations of materials can be utilized without departing from the scope of the-presentinvention. For example, the shell canibe made of paper, as described above, and the bands can be made of wood or metal, or the shell and band both can be made of metal. Another material that can be used for the shell or band or both is that commonly known as vulcanized fibre. As a matter of fact, the present invention is not limited with respect to thematerials utilized because any material that is suitable for containers made by other methods or of other types of construction can be utilized in making a container of the persent invention.

The modification shown in Figure 1l comprises staples 8|, or other suitable equivalents, for holding the reinforcing band to the shell because the band is not interlocked with the shell in the manner described above.

One outstanding advantage of a container constructed in accordance with the present invention resides in its strength and freedom from destructive distortion. It is well known in the art that the ends of a container are the parts that are most frequently subjected to abuse and they usually are the least capable of withstanding such abuse. If a cylindrical container is dropped so that it lands on one of its edges it is very likely that the head (or bottom) will fail to keep the container closed 'and the contents thereof will be spilled out. The shells illustrated and described in the present specification are not subject to such weakness. The end closure plates of the containers of the present invention are not held by nails or other Asimilarmeans driven through the shell and into the endy closure plate, as is the case in many of the containers heretofore known.v The means shown and described in this specification for closing the ends of the container provides a resilient construction that is capable of withstanding great abuse without giving way. Furthermore, the reinforced ends are stronger than the rest of the body and therefore can stand more abuse. The shell and band or bands of the present invention, being substantially integral, forma strong, undistortable `container body.

Another outstanding advantage of the containers of the present invention is that they are inexpensive to make. One reason for their low cost of manufacture! lies in their` simplicity?. They require no complicated devices for securing the end closure plates to the shell, norvdo they require extensive labor in their assembly. ,With the exception of the manufacture ofthe closure plates and the manufacture of the detents, the manufacture of the containers of the.

present invention is a winding operation andl that has been brought to ahigh state of perfection. The end closure plates, being of simple design, can bemade inexpensively, and likewise the detents,fwhich can be made by simple operations, such as stamping, are inexpensive to make. There beingno nails, rivets, staples or the like used in fastening the head (or bottom) to the shell, the labor cost of manufacture is reducedv to a minimum.

Another outstanding advantage of thepresent invention resides in the ease head (or bottom) can be secured in place and with which the.

removed after having been secured in place. As shown in the drawings, the head is set on the bulge 22 formed on the inside of thecontainer and a chime strip is then placed ontop of the head and in contact with the inside wall of the shell. Then the projecting ends of the detents are bent over the end of the shell and down intimate contact with the chime strip. This can be done'by hand because these detentsv can be -made of easily bendable material and still provide ample locking strength to keep the head (or bottom) in place even though the container is heavily loaded and is dropped on its edge.

When the detent shown in Figure 9 or that shown in Figure 10 is used it can be made of still more readily bendable material than that required for the detents shown in the other drawings. Inheadingup a container of the type shown in Figure 9 the head and chime strip are yput in place and then the detent is turned over an down by starting at one end of its projecting portion and proceeding with the turning over and down until theother end of the strip is reached.

'In opening a container that has been closed in the manner by which the containers of the present invention are closed, one merely straightens the detent or detents and removes the head and chime strip. l

Another advantage of the container of the present invention is that it can be repeatedly opened and closed up in the simple manner described above. No tools. are really required for either operation, but a simple screw driver can be used if desired.

Other advantages will be apparent to those skilled in the art of making containers and to the users of containers, but the foregoing are of such moment that further enumeration of advantages is not consideredl necessary to show the value of the present invention.
