2 Claims.
This invention relates to improvements in containers and like articles of manufacture.
Heretofore, it has been the practice in the manufacture of containers of the type generally described to first form the bodies and thereafter secure the bottoms in place in a separate operation. The labor and materials involved incident to this latter operation represent a substantial item in the cost of production of the containers. Apart from this, however, the mode of procedure described has the objection that permanent securement of the bottoms of the containers is not always effected while in many instances the joints between the bodies and the bottoms is not leakproof.
The principal object of the present invention, therefore, is to overcome the above objections, this object contemplating a container which is produced by a process characterized by the forming of the body of the container directly upon its bottom in a single operation.
A further object is to provide a container having a bottom which is effectively secured against displacement and which seals the end of the container against leakage.
A still further object is to provide a container which is simple in design, strong and rigid.
The invention is illustrated in the accompanying drawing in which:
Figure 1 is a side elevational view of a container produced in accordance with my invention. Figure 2 is an enlarged vertical section thereof.
The container, which may be made in various forms to meet the purposes and conditions of use desired or intended, is sufiiciently illustrated for the purpose in view by a showing of the body 5 and the head or bottom 6. The former may be formed of any suitable strip material, gummed paper for example, while the latter, as shown, is in the form of a wood disk having its under edge beveled as indicated at i, it being understood in this connection that the peripheral contour of the disk may be varied so long as the proper thickness is maintained and that that shown is by way of example only.
In accordance with the invention the strip material which is employed, and to which a suitable adhesive has been applied, is wound in spiral fashion, either with or without the aid of a mandrel, to produce a body having the desired wall thickness and length. During this operation the first few convolutions are wound directly about the periphery of the disk 6 which is to provide the bottom of the container, the initial convolution being started in such relation to the disk as to provide. a chime portion 8 of the desired height. Preferably the strip material is wound so that the chime portion will be at least a double thickness of the material in order to insure adequate stiffness.
As the strip material is wound upon the disk 6 it is held under a tension high enough to cause it to take the shape of, i. e. conform to, the periphery of the disk, the material of the diagonally extending zone of the strip which is acted upon by the disk being stretched or distended more or less in accordance with the particular circumferential portion of the disk which is engaged. In other Words there is effected, in varying degrees, a displacement of the material itself in the diagonally extending zone acted upon by the disk and not only is the body of the container caused to conform in shape to the periphery of the disc but the chime portion 8 is caused to taper in the direction of its lower end.
Upon completion of the winding of those convolutions which are acted upon by the disk, the remainder of the body may be formed in a spiral wound fashion. When a container of the desired length has been formed the open end may be reinforced, as illustrated by the winding of additional convolutions upon one another as indicated at t.
From the foregoing it will be apparent that the container produced as described has the advantage that the bottom is secured to the body in such a manner that it provides a leak-proof seal for the end of the container and cannot be removed without destruction of it or the body, any force acting against the disk in the o.;ection of the lower end of the body resulting in a firmer engagement between it and the body. The container has the. further advantage that it is strong and rigid in construction, the forming of the body directly upon the bottom rendering unnecessary the use of additional fastening means such as are employed when the bottom is secured to the body in a separate operation.
I claim as my invention:
1. The method of producing a container or similar article of manufacture consisting in forming a body of spirally wound strip material, the end of the body of the container being formed by winding the strip directly upon a member positioned thereon intermediate the edges of the strip, and holding said strip material under a high enough tension during the winding of said mediate the edges of the strip material and conconvolutions to stretch or distend certain zones stituting the bottom of the container, the pe-- thereof and cause them to embrace and contract riphery of said member having the lower portion about the peripheral edges of said member in thereof beveled and the convolutions of the body such a manner as to secure it against displace- 6 being stretched about the periphery of said memment, said member providing the bottom closure her to contract about its peripheral top and botof said container. tom edges to secure said member against dis- 2.
