3 Claims.
This inventon relates to a drinking cup pr'efe erably of conical contour and formed from a paper blank of improved construction and the object is to provide a cup of such conical shape 5 possessing sturdines's with reinforced walls and a heavily'reinforced apex portion for effectively eliminating leakage of water or other liquid.
An inventive featureof the formation of such blanks cut, embossed or otherwise formed from sheets or strips of paper of suitable quality, is the provision when built up on an appropriate mandrel (forming no part of this invention) in the usual manner, of amulti-ply area or field structure extending upwardly from the point or apex of the conical cup, insuring rigidity and strength as well as high liquid sealing qualities.
As stated, the blanks here shown, are shaped for convenient rolling on a mandrel for high production and similarity, and the cost of said production should be negligible, as little waste occurs in producing the blanks.
Other important features of construction are present which will appear in the description and claims including an initial back fold atthe start of the rolling operation of the blank on the above mentioned mandrel, providing a double ply porline l3 extends upwardly and outwardly to form an obtuse angle with said base line above the intersection therewith, this fold line is preferably embossed, and forms a hinge fora wing to be described. 5 Directly below the index point of the blank and beginning on the vertical line of that index, is an arcuate severance line H extending across through the base line H, to partially free from the lower right hand corner of the blank In an 10 adhesive carrying sealing head l5 thus leaving an integral neck It, and partially pointed terminal ll.
At the beginning of the rolling construction of the cup, a triangular reinforcing wing I! is turned 15 back from the folded line l3, from the severed line I, (Fig. 3) and is drawn under the first convolution of the major wall of the cup after tion and a rounded shoulder for stiifening the leading edge and for providing a wedging' action between the major convolutions of the cup blank on said mandrel, or between the mandrel itself and the first major convolution by folding the wing forwardly instead 'of backwardiy on said leading edge.
Fig. 1 shows a series of our, improved blanks 35 as cut from a strip of appropriate paper;
Fig. 2 is a side elevation of a completed cup and indicating by dot-and-dash lines, the relative position .of the blank with the apex of the cup resting on an index dot where it should rest the blank into a complete cup;
. in the convolutions of the head II in the Fig. 3 1s a partial diagrammatic view showing I the condition of the leading edge of the cup blank at the start of forming the cup, including a turned 45 back wing resulting in a double thickness and a shoulder for strength in the wall of the cup and further for assisting in rolling the cup after the major convolutions have been rolled to form major walls of the cup. 5 The blank may be described in detail as comprising a unit ll preferably cut or embossed in which the second convolution of the cup wall covers the reinforcing portion, thus forming a thin wedge between the overlapping main walls of the cup to prevent slippage during the application or spiraling of the sealing head II around the downwardly diminishing side walls to the apex of the cup for forming a multi-ply wall offeringa rigidly sealed structureagainst leakage and collapse. 7
Referring to Fig. '1 of the drawing an arcuate line of adhesive is is applied to the blank near to and in parallelism with the lower or trailing edge II, of the blank and is continued into the sealing head II to join a somewhat wider cross line 2| forsealing'the walls ofthe cup and seallflnis in: operation ofthe cup structure.
What we claim is: v I
l. A blank for forming paper drinking cups having a quadrantal outwardly curvedside edge and a lower' upwardly curved edge connected by a straight'base-line through irregularly curved40 edges, said blank also having, an index on its surslightly below said index and extending hori- 4 F zontally to said baseline for forming a partially free sealing head at the lower right corner of said blank, and an arcuate line of adhesive applied to the blank near and in parallelism with the said lower arcuate edge of said blank and terminatlng within the sealing head in a Joint with a vertically disposed cross of adhesive extending short of the upperand lower edges of said'sealing head, said arcuated line of adhesive fixing the overlapping trailingedge of the blank to he 86 leading portion of the blank in face to face contact and said adhesive cross of the sealing head acting to secure the convolutions thereof to the apex portion of the cup in spiralling relation and to the extreme point of the cup.
2. A cup made from a paper blank, said blank having a general quadrantal form with a convex upper and side edge a concave bottom edge connected by a straight line; the blank having a' 3. A cup made from a paper blank, said blank comprising a general arcuate quadrantal form and a straight edge, said straight edge constituting at its upper-part of the cup the leading edge in its formation; a wing folded back from said leading edge for forming a rounded shoulder and a two ply wall beginning at the apex of the cup and which is rolled into the cup structure and finally disposed between the major walls at and slightly above the apex of the cup; a sealing head having a foldable neck from which said head is extended into spiral layers of reinforcing material around and over the apex of the cup including the major walls and the said reinforcing wing portion.
