PAPER RECEIPTACLE.

Specification of Letters Patent. Patented Apr. 26, 1910,

Application filed September 19, 1908. Serial No. 453,894.

To all whom it concern:

Be it known that I, JOHN N. DAVIS, a citizen of the United States, residing at Dayton, in'the county of Montgomery and- State of Ohio, have invented certain new and useful Improvements in Paper Receptacles, of which the following is a specification.

My invention relates to receptacles of paper or similar material and more particularly to bottles of such material.

The object of the invention is to provide a bottle constructed'of paper or similar material which will be sanitary, simple in structure strong and durable to enable it to withstand the action of liquids, and which may be manufactured byunskilled labor at such low cost as will permit it to be discarded .when once used.

A further object is to provide a vessel of such character; which will be symmetrical, pleasing in appearance, and substantially conforming in contour to the usual shape of bottles heretofore used.

A further object is to provide an improved form of closure devicefor such receptacles, which will be -more effective in protecting the contents of the receptacle from the entrance of foreign matter.

With the above primary and other incidental objects in View, the invention consists of certain features of construction, devices,

parts and combinations thereof, or their equivalents, as hereinafter described and set forth in. the claims.

In the drawings Figure 1 is a perspective view of the complete receptaclewith the closure device in place. Fig. 2 is a vertical sectional view of the complete receptacle. Fi s. 3 and 4 are plan views of the outside and inside wall members respectively. Fig. 5 is an enlarged detail sectional view of the upper portion of the receptacle. Fig. 6 is a similar view of the lower portion of the receptacle. Fig. 7 is a view similar to Fig. 6 illustrating an alternative construction. The thickness of the paper as shown in Figs.'5, 6 and 7 is greatly exaggerated, showing recesses between sundry layers of paper which in reality would not exist, or would be so small as to be unnoticeable in the device when constructed from stock of usual thickness. 'Figs. 8 and 9 are detail views of annular reinforcing members for the bottom of the receptacle. Fig. 10 is a sectional perspective view of the closure cap. Fig. 11 is upper part of the bottle, showing the four fold seam of the inner wall.

Like parts are indicated by similar char- -acters of reference throughout the several views.

The bottle as illustrated comprises a vessel cylindrical throughout a portion of its height, and inclined or conical throughout the remaining portion. The vertical walls or the cylindrical portion are of three thicknesses, while the upper portion which is in the formof a truncated cone attached to said cylindrical portion is of double thickness, the double walls being scored and folded to cause the walls to contract to the re-- duced mouth.

In constructing the receptacle there is employed a cup shaped member 1 which may be formed by gluing and folding a paper blank in the well known manner, but is preferably formed from a paper blank by stamping, or by the use of suitable forming dies, whereby the paper cup will be a seamless body. There are provided inner side walls 3, which extend down within the cup 1 substantially to the bottom thereof, and outside walls 2 which inclose the cup 1 and the inner walls. The outside walls 2 are formed from' a single blank of rectangular form shaped and "scored as shown in Fig 3, in which 4 are triangular, rentering gores formed by scoring the blank, which gores, when theblank is folded on the score lines cause the upper part of the bottle to assume the conical form. At 5 is provided a portion to form an overlapping glue joint, by

which the two sides of the blank are united.

The inner wall blank is shaped and scored similar to the outside wall blank, the gores 6 of the inner wall corresponding with those 4 of the outside wall. Glue laps 7 are provided at each end of the blank, by which the blank is formed into a cylindrical body. The glue sections, 7 are first joined, then the blank is folded on the score lines at each side of the glue joint to form' a four fold seam, formed by the interlocking of the reversed edges of the blank, which incloses the glue joint and protects the contents of the tom of the cup, the upper part of the -receptacle is contracted b plaiting the walls, or folding inward the'gores 4 and 6 of the respective walls 2 and 3, which forms verti cal plaits in the bottle wall as shown in Figs. 1 and 2. The inclination of the upper part of the bottle may be varied more or less by varying the proportions of the gores etand 6,

making them wider and shorter for a more abrupt top, and long and narrow for a slight tapered bottle. When the upper part has been contracted by the folding of the gores on the score lines, the tongues 8 projecting from the upper edge of the inner wall are bent outward over the edge of the outside wall and attached thereto by glue or otherwise. This will serve to unite the double wall, and form a smooth finished edge. Annular reinforcing members which may be in the form of a band 9, as in Figs. 6 and"8, or one or more flat rings, as in Figs. 7 and 9 are inserted within the extended outer wall 2 below the bottom of the cup 1, over which reinforcement, the lower edge of the outer wall is turned inward, as in Figs. 6 and 7, forming an annular flange or rim aboutthe bottom of thereceptacle on which the cup 1 will rest, and which will materially strengthen the bottom of the receptacle to enable it to withstand the weight of the con tents.

Fitted over the top of-the receptacle is a collar comprising an internal flange 10 adjacent to the mouth of the bottle, having a peripheral flange s stantially inverted U shaped, extending pward 'on' the interior and another at 15. It is to be understood that the thickness of material is greatly exaggerated in this View, and that such recesses do not in fact exist in the device constructed from material of proper thickness, but such recesses are due to the exaggeration of the view. A closure disk as is incommon use for closing milk bottles may be used with the receptacle, such disk being pressed within the mouth of the receptacle until it rests on the flange 10 of the collar. However such disks have been found undesirable for the purpose of closing milk and other bottles, because dirt and foreign matter collect on top of the disk within the orifice of the receptacle. To remove such disk closures it is usual to pry the disk up, the tilting of which in the removal operation results in spilling the dirt from-the closure disk into the contents of the receptacle. To obviate this difficulty, there is provided a closure device formed from a single piece of material by stamping or otherwise, which rests on the flange 10 and overhangs the upper edge of the receptacle walls.

The closure comprises a cup shaped member 16, the peripheral flange 17 of which is recessed, or substantially inverted U-shaped, within the recess of which the edge of the receptacle -wall extends. The closure device is somewhat similar in shape and in application to the receptacle, to the collar before described, except that the horizontal portion of the collar is provided with a central opening, whereas that of the closure is continuous or solid. B the use of the closure as described, any dirt or foreign matter which might be on the closure will be removed therewith, and can not accidentally fall into the receptacle. The flange 'of the closure engaging closely both the inside and outside of'the edge of the wall forms a slop proof joint, which not only prevents the entrance of foreign matter but also prevents the escape of the contents of the receptacle.

It is obvious that instead of the gores 4 and 6 in the walls of the receptacle, such Walls might be corrugated without scoring the material such corrugations being compressed at thetop, somewhat fan shaped to form the tapered portion of the receptacle.

From the above description it will be ap parent that there has been thus produced a receptacle 1 of the character described, in which the glue joints will be protected from contact with the contents thereof, and which possesses the sundry other features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention, I claim:
