. d Patented Sept. 23, 1930 UNITED ISTATES PATENT oFEicE lKONOSUXE TSUCHIYA, 0F SAUSALITO, CALIFORNIA LIQUID CONTAINER Application led March 19, 1929. Serial No. 348,167.

The present invention relates to improvements in -liquid containers and more particularly to that type of container commonl own as a milk bottle or receptacle.

The invention consists primarily in-a tubular bod preferably of paper pulp structure suita l coated to prevent liquid penetration, andy which may be cheaply manufactured and readily disposed of when its use is discontinued.

ong its objects, the present invention affords a container body open at its opposite ends and adapted for storage or stacked in nested formation, enabling the conservation of space. Another object is the provision of a bottom wall holding groove which aords a circumferential reinforcement for the lower edge of the container. A. further object is to provide a bottom wall or'closure member insertable into the container through its open bottom and which has tight seating contact within the' bottom holding groove and which is further forced into contact with said groove by the weight of the contents of the container. A A With the above mentioned and other objects in view,the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the appended; it being understood claims hereto x that various changes in the form, proportion,

. size,I and minor-details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any tion.

To more clearly comprehend 'the invention, reference is directed tothe accompanyin drawings, wherein 2 igure 1 is, a view in vertical section of a plurality of my improved containers 1n nested formation. .Y i v Figure 2 is a similar view with the closure ca and bottom wall in osition. p ,liigure' 3 is a view in etail cross section of the bottom swell. I Referrin more particularly to the drawings wherein like characters oireferenc'e designate corresponding parts, l indicates a tu- Vouter Wall of the and inwardly curved of the advantages of the invenbular cylindrical body, open at its upper end at 2, and at its lower end at 3. he member l is preferably constructed of heavy paper, such as paraiin stock or is formed from paper pulp by any of the well known methods, and its surface, particularly its inner surface, is coated to preclude the admission of moisture thereinto. The upper end of the body l is tapered at 4 and is vertically ribbed at 5, the ribs affording strengthening means for the neck ofthe body. The member l slightly tapers or Hares from a point below its neck to its bottom edge, enabling succesive bodies, when their closures are eliminated from the ends, to be arranged in telescopic or nested formation, as in'Figure 1.

At its extreme upper end the body l is formed with a closure seat 6, on which is adapted to rest the peripheral edge of a conventional milk bottle closure or cap- 7.

1N ear its lower end the body 1 is circumferentially grooved at 8, the groove opening on the inner surface ofthe body and the groove adording a circumferential reinforcing rib for the lower portion of the body 1. The groove is provided with a bottom wall 9 disposed at substantially right angles to the and is further provided with an upwardly wall 10 connecting the outer edge of the bottom wall with the wall of the body. f

The .bottom closure member comprises a disc 1-1- of. a diameter for the snug reception of its peripheral edge into the groove 8, and the body of said. disc is formed with a crowned center or surface 12. The peripheral edge of the disc is curved in cross section to correspond with the cross sectional curvation of the groove 8, and is also provided with a circumferential vertical Wall 13 for contacting with the inner surface of the body 1 immediately above the groove 8, as in Figure 2. The disc ll is inserted in position by slightly distorting the same and forcing it upwardly into the body l through its open bottom, the edges of the disc springing into place, as in Figure 2. 'p

As the receptacle receives its contents, the Weight of the contents on (be crown center wall of the receptacle Civ l succeeding time,

lar container body a the wall of sai tends to force the same into a horizontal plane, andin doing so, peri heral edge of the disc against the wall of t e groove 8. y

When the container is used for a dry commodity, it may be disassembled and used a but it is designed preferably for ready disposal after being used for a wet commodity, and without I claim 1. A liquid container comprising a tubuof rigido structure having a frustum conical upper portion superposed on a cylindrical lower portion, which lower portion is provided spaced relation to its open bottom with a circumferential groove opening inwardly into the container, said groove provided with a bottom Wall disposed at substantially right angles to the wall of the receptacle, and further provided with an upwardly and inwardly curved wall connecting the outer edge of" the ,bottom wall of the groove with the container wall, a disc-shaped bottom closure havinga crowned center and peripherally flanged to correspond to said groove, .said bottom closure adapted for insertion into the container through its bottom.-

2. A liquid,container comprising a tubuf lar receptacle structure open at its opposite ends and outwardly Haring from top to bo tom to adapt the same for nesting and providing a taperin shoulder within its length, receptacle being plurally grooved intermediate the shoulder andtopv and being provided near and in spacedrelation to its lower edge with an integral outwardly disposed annular bottom- Wall seat, the lower surface of which lies at substantially right angles to the 'inner wall of the receptacle, formation ceptacle with its edge the top portion formed outwardly providing a circular opening adapted to receive a closure cap therethrough, and having associated with said y opening aV shoulder adaptedto receive and support the closure cap.

In testimony whereof I havername to this specification.
