a disk set into the tapered body.

I am familiar with a paper drinking cup comprising a tapered body and a disk set thereinto and constituting the bottom therefor. In this old form of cup, the disk usually has paste applied to its periphery and I is then forced into the lower portion of the no outlet therefor.

body. The forcing of this bottom or disk to its sea-t squeezes the paste from between the bottom and body so that the paste will be run onto the interior of the body above the bottom which is objectionable for several reasons, the most pronounced and rominent being that the paste area in said ody cannot be properly covered with the paraflin which is used subsequently to coat the cup. Another objection to this old t pe of cup is that the bottom can be easily orced from place especially when the same is. subjected to the pressure of a falling stream of water. In this old type of cup the bottom is set some distance above the lower edge of the body thus forming a cavity below said bottom. When the paraflin is applied to the cup it is in inverted relation and the paraflin collects in this cavity in that there is It has been the custom to grasp this old cup by hand before the paraflin is set, and to turn it right side up so as to permit the molten paraflin to run out of said cavity and in doing this the 'fingers mar the cup. I provide a construction wherein the disadvantages alluded to are eliminated. The bottom of my on is substantially and securely held against downward displacement, while there is no possibility of paste reaching the inside of the body. I also provide for the rapid and thorough escape of the liquid parafiin in the cavity or pocket when the cupis inverted during coating.

ceeding said description.

In the drawings accompanying and form- (mg part of the present specification I have shown in detail several convenient forms of embodiment of the invention which to ena'ble those skilled in the art to practice the same will be set forth fully in the following description, while the novelty of the invent-ion will be included in the claim suc- From this observation it will be evident that I do not restrict myself to such showing; I may de-v part therefrom in several respects within the scope of the invention included in said claim.

.Referringto saiddrawings: Figure 1 is a vertical section of a drinking cup involving my invention. Fig. 2 is a bottom plan view of the same, and, Figs. 3 and 4 are views corresponding respectivel to Fi 1 and 2, of a modified form of cup gs Like characters refer to like parts throughout the several figures.

Referring first to Figs. 1 and 2. The drinking cup shown in these figures comprises a body 2 and a bottom 3, and while as previously intimated, I do not restrict myself to any particular form of body, it is with advantage made of tapered or conical form in that a body of such sha aids in holding the bottom 3 in place. f course, I do not rely upon the tight fit of the bottom in the body to hold the bottom against displacement, as I find that this will not answer. I provide means of a positive and certain nature to obtainthis result as will hereinafter appear. made from a sheetof paper rolled to tubular shape upon a mandrel or otherwise formed. The bottom 3 may consist of a disk. As a matter of fact and as already intimated the body and bottom as thus far described are not novel, for which reason it is needless for me to go further into details with respect to these features, the invention residing in certain points hereinafter set forth. After the body 2 has been shaped up and the bottom 3 inserted thereinto, said body below the bottom will preferably have punched therefrom several tabs or cars as 5; there may be any desired number of these tabs or cars, for example, eight, although this number is not essential. The tabs or ears 5 will be preferably adhesively united to the under surface of the bottom 3 by applying paste either to the ears or to the under surface of the bottom. It will be as The body 2 may be.

sumed that the ears 5 have been punchedfrom the stock of the body. When this is accomplished I may for example apply to the inner surface of said ears paste or cement, after which the ears are pressed firmly against the bottom so that when the paste is set or hardened, said bottom will be substantially connected to the ears, by virtue is of utility as will now appear. As already stated the cup is coated with paraflin, the paraffin during such procedure, fallingin a stream onto the cup, while inverted. Naturally this paraflin enters the cavity or chamber in what is. for the time being the upper part of the cup. Owing to the presenceof the outlet formed for exam le by the holes or slots'ti, the excess para n can freely flow out of this cavity so that there,

is no necessity for subsequently tipping the cup to empty said cavity. 'It will be clear also that owing to the fact that the bottom 3 is united to the ears 5 below the bottom, there is no possibility of any of the paste which unites the bottom and ears getting into the inside of the cup above the bottom so that when the parafiin flows through the body as is the case in practice the cup interiorly of the same can be uniformly and evenly coated with such substance. 1

I desire to call attention to the fact that the tabs or ears 5 fit fiatwise against the under side of the bottom 3, by reason of I which the holes or slots 6 are wholly uncovered, and by virtue of which when the cup is inverted as already set forth the fluid paraflin or equivalent substance can freely and unobstructedly pass through these holes 1 or slots.

In Figs. 3' and 4 I'have shown a modified form wherein the body 7 has cut or punched from the lower edge thereof the tabs or ears 8 which are adhesively united'with the bottom 9. In view of the cutting of the ears 8 from said body 7 there are formed in the lower edge thereof slots or notches 10 through which the parafin can flow from the cavity in the bottom of the cup during the paraflining operation.

What I claim is:

A paper 'drinking'cup comprising a body,

and a bottom fitted in said body, above the lower edge thereof, the body having several.

lugs punched therefrom below said bottom .60

the cavity in the lower part of the cup can freely pass through said holes.

In testimony whereof I afiix my signature in presence of two witnesses.
