14 Claim.
This invention relates to improvements in a container, and more particularly to a container of the type of a drinking cup, ice cream cup or production is most desirable, if not essential. It is also desirable to provide a container blank of such a character that successive blanks may readily be severed from a substantially continuous sheet or strip of stock.
With the foregoing in mind, it is an important object of the present invention to provide a blank for making a container, which blank comprises an exceedingly small amount of stock.
Another object of the invention is the provision of a container blank which may be cut from a continuous strip of stock in such a manner that the blank, together with the wastage contingent with the cutting thereof, reaches a desirable minimum.
A further object of the invention is the provi- 30 sion of a container blank having a substantially straight edge, which blank may besevered from a continuous strip of stock with such straight edge coinciding with an edge of the stock strip, the blank being complete in nature when severed 35 from the stock strip and not requiring any further trimming or cutting operations.
Another feature of the invention resides in the provision of a container blank-which lends itself to a simple and economical method of forming the resultant container.
It is also an object of this invention to provide a blank for forming a container of substantially true conical shape, the blank having a pair of substantially straight edges joining a pair of 45 arcuate edges, the arcuate edges being of equal radii.
A still further feature of the invention is the provision of a quadrangular blank for forming a container of substantially true conical shape,
50 the blank having an arcuate leading edge and being wound into conical shape about a point substantially opposite the center of said leading edge but spaced inwardly therefrom.
Another object of the invention is the provi-- III sion of a container of substantially true conical shape, made from a single blank of material,- with marginal portions of the blank overlapped to form a seam which is of substantially the same width throughout its length.
A further object of the invention is the provi- 5 sion of a blank for making a container of substantially true conical form, the blank being of such shape and character that the completion of the-formation of the apexial region and the tight sealing of this region in the resultant container may be effected by forcibly nesting the container being formed in a stack of previously formed and nested containers of similar character.
While it is known that a blank for the formation of a container of substantially true conical shape must be provided with an arcuate edge for defining the mouth of the container, it is an important object of the present invention to provide a blank having an arcuate leading edge opposite to the edge defining the mouth of the container, which leading edge is substantially blsected in the formation of the container, and two halves of this edge are brought up and disposed in the body part of the container, which construction lends itself to an economical method of forming the container.
Still a further feature of the invention is the provision of a blank for forming a container of substantially true conical shape, which blank is substantially symmetrical in shape, i. e., having coinciding halves if folded along an axis of the blank.
While some of the more salient features, characteristlcs and advantages of the present invention have been above pointed out, others will become apparent from the following disclosures.
taken in conjunction with the accompanying drawings, in which:
Figure 1 is a fragmentary plan view illustrating how the blank embodying principles of the present invention lends itself to-being cut from a continuous strip of stock;
Figure 2 is a side elevational view of the finished container;
Figure 3 is a top plan view of the finished container;
Figure 4'is a bottom plan view of the finished container;
Figure 5 is a fragmentary plan view illustrating a step in the forming of the blank into the container and showing certain salient points in connection with the blank and container;
Figure 6 is an elevatlonal view taken from the right of Figure 5; and
Figure 7 is a fragmentary view, partly in section and partly in elevation, illustrating how the particular blank lends itself to a simple method of forming the container.
As shown on the drawings:
In the illustrated embodiment of the present invention, there is seen a blank II) which is a substantially fiat sheet of stock, which may be paper of the character used in making paper drinking cups, the so-called dry wax paper being a. satisfactory example. In the illustrated instance, as seen clearly in Figures 1 and 5, the blank I0 is of such a shape as to include a relatively long arcuate edge II to define the mouth of the resultant container, a pair of substantially straight side edges I2 and I3, and another shorter arcuate edge I4 which is the leading edge of the blank during the formation of the cup or container.
The arcuate or mouth edge It substantially terminates in the side edges I2 and I3 which are preferably non-radial with respect to the mouth edge II and which converge in a direction away from the edge II, but do not meet. These side edges are joined at theirnearer ends by the arcuate edge i4, so that the complete blank is quadrangular in shape and comprises a pair of opposed substantially straight side edges and a pair of opposed arcuate edges. Preferably, the arcuate edges II and it are of equal radii, and in the illustrated instance the center of curvature of the edge II is substantially at the midpoint of the edge I4, and the center of ourvature of the edge I4 is substantially at the midpoint of the edge II.' Thus, the center of curvature of the mouth defining arcuate edge II is within the area defined by the major bounding edges of the blank, and would so be even, for example, if one of these bounding edges was notched around said center so the center would, in fact, be off the paper proper. It is apparent, therefore, that the complete blank is substantially symmetrical in that if the blank were folded on the median line from the edge II to the edge I4, both halves of the blank would coincide with each other.
It might be noted that in the event it is desirable to form the blank into a conical container with the use of a rotating mandrel embodying a gripper for grasping an edge portion of the blank, after which the blank is wound or wrapped around the mandrel, one of the edges I2 or I3 may be made slightly concave to facilitate the winding action, all in an obvious manner and without departing from the spirit of the invention.
The blank I0 lends itself to being out from a continuous strip of stock, such as the strip I 5 seen in Figure l, and blanks may be successively severed from the strip, as indicated in this figure. It will be noted that one of the side edges of the blank, in this instance the edge I2, coincides with the side edge of the stock strip, to eliminate wastage of material. Of course, as the blanks are successively cut from the strip I5, there will be some wastage of stock which is indicated at IS in the right-hand portion of Figure 1, but it will be noted that the stock strip I5 is relatively narrow and that the blank itself together with its proportional amount of the wastage I6 results in the use of an exceedingly small amount of stock for each container.
While the method of forming the blank into container-shape is described and claimed in my co-pending application, Method of making a paper cup, filed August 12, 1938, Serial No. 224,480, certain steps of the method are presented herein for the purpose of clarity, to indicate how the blank, by its own shape, lends itself to an economical method of forming.
With reference to Figures 5 and 6, it will be seen that the blank Ill may be wound or wrapped around a conical mandrel H which is preferably non-rotative. The winding of the blank is centered around a point I8, in this instance the apex of the mandrel. It will be noted that this point I 8 is substantially opposite the midpoint o! the arcuate edge I4, but is spaced from this point so as to lie inside the blank proper. While the location of the point I8 may vary to some extent, it has been found that a tighter seal can be made at the apex of the cup if the point I 8 is spaced inwardly from the edge I4, rather than coinciding with this edg.
The edges I2 and I3 are brought around the mandrel I'I so that the marginal portions adjacent these edges overlap to form a seam. It will be noted that the blank carries a suitable adhesive I9 for retaining the margins overlapped. In actual commercial practice, the adhesive I9 would probably be on the opposite side of the blank from the illustration in Figure 5, so that the adhesive would be on the outside of the inner margin of the seam. However, for the purpose of clarity in illustration, the adhesive is illustrated as being on the inside of the outer margin of the seam.
With the illustrated showing, the edge I2 would first be brought around the mandrel, and then the edge I3, to providethe overlapped marginal seam 20 illustrated in Figures 2, 3 and 4. Of course, suitable pressing means may be utilized to press the overlapped margins together and thus insure a bonding by the adhesive.
It will be noted that in thus forming the blank around the point I8, the arcuate edge I4 is substantially bisected, and the two half portions of this edge are brought up onto the body of the blank in overlapped relationship as a continuation of the seam 20, illustrated in Figures 2, 3 and 4, thus providing a. tightly sealed apex for the cup or container amply sufilcient to prevent leakage of liquid contents.
It will further be noted that the seam 20 is of substantially the same width throughout its length, with the exception of the margins adjacent the halves of the arcuate edge I l, and that the halves of the arcuate edge ll, as nearly as possible consistent with this edge being arcuate, coincide in the finished container with an element of the cone, as seen best in Figure 2, so that the container is not only highly efficient in use but very pleasing in appearance.
At the time of the formation of the seam 20, the apexial region of the cup, especially in the vicinity of the half portions of the arcuate edge I4, is not tightly sealed, and this is accomplished by forcibly nesting the container in a plurality of completely formed and nested containers held under pressure against expanding to full size at the open ends.
In Figure '7, there is illustrated diagrammatically a chute or receiver 2| having a bore 22 at one end and a larger bore 23 at the other end, a shoulder 24 resulting from the differently sized bores. A plurality of completely finished containers 25 are shown in nested relationship in the receiver, and these containers have been forcibly pressed from left to right in the smaller bore 22 which is of such a size as to prevent complete arcane expansion of the mouth edge of the container. The container being formed, shown on the mandrel i1, is forced into nested relationship with the containers 25 in a manner sulllciently positive and under sufficient pressure to insure atight seal of the apexial region of the container. As successive containers are forced into the smaller bore 22, containers are successively pushed into the larger bore 23, wherein after the mouth end passes the shoulder 24 the containers may expand to their full size an thus become loosened from the following cont ers.
From the foregoing, it is apparent that I have provided a novel container of substantially true conical shape, and a single novel blank for forming the container, the blank requiring the use of avery limited amount of stock and lending itself to the easy and eflicient cutting of the blank as well as asimple and rapid method of forming the container, whereby the container may be manufactured expeditiously and very economi cally. It will be noted also that the container is not only pleasing in appearance, but highly efficient in operation and may be utilized for holding liquids, solids or frozen confections.
I am aware that many changes may be made and numerous details of construction may .be varied through a wide range without departing from the principles of the present invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise thanis necessitated by the prior art.
