DRINKING-CUP.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed January 27. 1915. a Serial No. 4,704.

This invention contemplates an improved drinking cup and has as its primary object to provide a device of this character employing a construction especially adaptedto the use of paper or other fibrous material in the formation of the cup. I

The invention has as a further object in this connection to provide an improved cup having as it's salient feature, simplicity of construction, while at the same time, a thor-' oughly' efficient article will be produced.

A still further object of the invention is to provide a cup so constructed that the elements thereof may be readily formed, and wherein the individual elements of the cup will be such, that but a minimum amount of stock will be wasted in forming the blanks providingthe said elements, from the stock.

Other and incidental objects will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views, a V

.Figure 1 is a perspective view of my improved cup. Fig. 2'is afragmentary sectional view illustrating the construction and mounting of the bottom wall of the cup. Fig. 3 is a view on a slightly reduced scale showing the blank from which the side wall of the cup is formed. Fig. 4 is a detail sectional view illustrating the manner in which. the side wall of the bottom of the cup is plaited or crimped to fit within the body of the cup. Fig. 5 is a fragmentary sectional view disclosing the arrangement of the ad hesive receiving channels formed in the side wall of the bottom of the cup, and Fig. 6 is a fragmentary sectional view showing a slight ,modification in the mounting of the bottom of the cup.

In carrying out my invention, I employ a blank 10 which as best shown in Fig. 3 of the drawings, is formed from a single piece of material. The blank 10 may be struck from a piece of preferably paraffin paper stock, although Manila paper of itable character could also be employed, where desired.

It will be observed upon reference to Fig. 3 that the end edges of the blank 10 are stralght and uninterrupted and converge toward one side edge of'the blankupon radial lines. The side edges of the blank are also uninterrupted and are each defined by an are having a center common to both.

Formed in the blank 10 adjacent one side thereof is an arcuate channel which is preferably pressed into the stock to provide a longitudinally extending rib 11. The blank thus formed is rolled longitudi nally to form the substantially frusto conical body portion 12 of the cup, the end margins of the blank being arranged in overlapping relation as best shown in Fig. 1 of the drawings and being adhesively connected to each other or secured together in any suitable manner. It will be noted that the rib 11 is thus disposed adjacent the upon the side wall of the cup adaptedto engage the upper edge of an adjacent cup when several of the cups are nested.

Particular attention is now directed" to the fact that throughout the overlapping portions of the side wall of the. cup, the shoulder provided by the rib 11 upon the inwardly disposed overlapping portion, is adapted to engage within the channel formed by pressing the rib outwardly, as previously referred to, of the outwardly disposed overlapping portion. As will be clear, such engagement of the shoulder within the channel at the point mentioned will efiectually counteract any t ndency of the overlapping ends of the side wall to shift relative to each other in a vertical plane, and will coact with the adhesive securing the overlapping ends together, for providing an eflicient and rigid structure. The bottom similar vto that employed in forming" the body of the cup. As will be readily seen, upon reference to Fig. 2 of the drawings, the blank providing the bottom wall 13 pre vious to being bent as shown therein, is substantially circular, and adjacent its periphery, is bent laterally to provide an ancontour. Formed in the upper free margin of the side wall 1 1 are superposed series of circumferentially extending reversely 'presented inner and outer plaits designated 15 and 16 respectively, which extend vertically of the said side wall, and, as best shown in Fig. 2 of the drawings, taper in widthjas they approach the bottom wall 13, the individual plaits of each seriesbeing arranged in staggered relation to adjacent plaits of the other series.

In this connection, particularattention is directed to Fig. 4 of the drawings wherein the construction and arrangement of the plaits 15 and 16 are particularly shown. It will be noted that each plait of the inner series of plaits 15 has its longitudinal side walls arranged in spaced relation to the confronting ends of adjacent plaits of the said series and merges, at its sides, with the sides of adjacent superposed plaits of the outer series of plaits 16. As in the case of the inner series of plaits 15, the individual plaits of the outer series of plaits 16 are also preferably each arranged with their sides disposed in spaced relation to the confronting ends of adjacent plaits of the said outer series. By this arrangement, the wall 14 adjacent the upper margin thereof is made expansible whereby the circumference of the said wall, throughout the greater portion of its length may be either increased or diminished and attention is called to the fact that each individual plait of the inner series of plaits 16 in connection with the confronting ends of adjacent superposed plaits of the outer series of plaits 16, provide vertically arranged channels 17 tapering in width toward the bottom wall 13.

As best shown in Fig. 2 of the drawings, the series of plaits 15 and 16 respectively merge at the lower extremities thereof, into the inner and outer surfaces of the side wall 14, to provide, upon the outer face of the cup and adjacent the bottom wall 13, an annular substantially smooth and uninterrupted bearing surface 18.

The bottom of the cup is preferably arranged within the smaller end of the body portion 12 as shown in Fig. 2 of the drawings and the outside diameter of the bottom wall 13 is such that the bottom of the cup will fit snugly within the side wall thereof to frictionally engage the inner face of said wall, the bottom wall 13 being preferably arranged in a plane with the bottom edges of the body of the cup, with the side wall 14 flaring outwardly to seat against the said side wall adj acentthe lower margin thereof.

Particular attention is now directed to the fact that the bearing surfacelS of the side wall It will have uninterrupted engagement with the inner face of the side wall of the cup and will thus close the channels 17 at their lower ends. It is further to be noted that the inner and outer series of plaits 15 and 16 may be expanded or contracted so that the wall 14 will yieldably engage against the side wall of the cup to thus pro vide an effective closure. Previous to so disposing the bottom of the cup within the body portion thereof, the outer faces of the outwardly disposed series of plaits 16, are coated with paste or other suitable adhesive while the channels 17 are preferably entirely filled with such adhesive. Thus, when the bottom of the cup is applied as just above described, the adhesive within the channels 17 will beheld therein through the engagement of the bearing surface 18 eter greater than the diameter of the cup taken in a plane with the upper edge of the wall 14. Consequently, when the bottom of the cup is disposed in position, the spaced confronting edges of the inner series of plaits will be moved toward each other, and this will also occur in connection with the outer series of plaits 16. The wall 14 will thus adjust itself to the diameter of the cup in a plane passing through the said wall and will therefore, being vthus expansible, compensate for any unevennesses in the side wall of the cup adjacent the lower end thereof.

When the outer series of plaits 16 are thus moved toward each other as just above described, the width of the channels will be correspondingly decreased so that the adhesive contained within the said channels will be forced outwardly against the contiguous. portions of the inner face of the side wall of the cup to thus efiectually secure the bottom wall in position, it being In Fig. 5 of the drawings, I have illustrated a slight modification of the invention which consists in reversing the disposition of the bottom 13 of the cup from that shown in Fig. 2. Otherwise, the elements of the cup are con tructed n. the sa e manne as above described with reference to the preferred form of the invention and will also coact in a similar manner to produce the finished article.

It, will therefore be seen that I provide an exceedingly simple and desirable construction wherein to produce the cup. but two separate elements are employed which are so formed and arranged as to provide a thoroughly eflicient article of manufacture.

Having thus described my invention, what I claim and desire to secure by Letters Patent is g An article of the character described including a body portion. and a closure fitted within the body portion and provided with a securing wall having one margin thereof plaited to form a series of adhesive receiv- BOXIFACE A.
