To all wom it may concem;

. Be'itknown that we, FRED W. BAUER and fKnurrmv, citizens of the United county of Milwaukee,and State of Wisconsin, have invented new and useful Improvements in Paper Boxes for Liquids, of which the following is a speciicatlon.

Qur invention relates to improvements in paperboxes for liquids.

The object of our invention is to provide a form of box havin a sealed closure and adapted to be used -or containin liquids, whereby the same mayserve for bottles and other liquid containing receptacles which have heretofore been usually composed of glass or metal.

' similar view of the outer closure member.'

A furt provide means whereby except the closure, may consist of a single integral and unslit sheet of paper bent or folded to produce the bottom and side walls of the receptacle.

In the following description,reference is had to the accompanying drawings, in which- Figure 1 is an elevation of our improved receptacle. Fig. 2 is a, vertical sectional view of the same with the closure members removed. 'Fig'. 3 is a vertical sectional view of the inner closure member.V Fig. 4 isa all of the receptacle,

Fig. 5 is a cross sectional view of the receptacle drawn on line w-:v of Fig. 2.- Fig. 6 is a plan view of the'blank from which the bottom and side walls of the receptacle are formed. Fig. 7 is a plan view of the blank from which the inner closure member is formed. Fig. 8 is a plan view of the blank from which the outer closure member or cover is formed.

Like parts are identified by the same reference characters throughout the several views.

The side and bottom walls of our improved receptacle are formed from a substantially square sheet of aper having projecting tongues d in the mlddle of each side, and having a square section of its camels cut out as shown at f in Fig. 6. This sheet of paper is subdivided by creasesor diagonal folding lines 1, into four equal parts connected with each other by a square central ortion e, which central portion e forms the bottom of the receptacle 'when the latter is completed. Each of these vfour equal parts Speccation of Letters "Application :lled December 14, 1911. Serial Re. 865,803!

i is further subdivided by folding iines 2,12, l3 and 4 into sections a, b b and c c. .The

folding lines 1 are creased `to permit an upward and inward folding movement. The folding lines 2 are creased to permit the sides b to fold inwardly at right angles tothe Section a. The folding lines 3 of each section are creased to permit folding in the reverse direction, while the folding lines 4 are creased to permit folding of the section c upwardl and inwardly in the same direce section b' is folded. The varions sections are therefore adapted to be folded upon each other as illustrated in Fig. 5, the crease 3 of each part being brought into with the crease 4 of the 'adjacent pint, which crease 4meets the crease 3 in t e folding line or crease l. When so folded, the sections on opposite sides of the folding line 1, will lap together as follows -The sections b b', which meet in one of the lines 1, will lap together and fold upon one of the sections a. The sections c c', which also meet in said line l, will lap together and be together folded over and upon the outer of the two sections b b', thus making, (at the upper portion of the receptacle), a series of overlapping walls a, b b and cc', the sections ce and?) b being held against the .wall by folding the projecting member d inwardly and downwardly to engage their upper edges. The sections b b and c c between any two sections a, are thus folded upon one of such sections a, and as there are four sections a, each may thus receive one set of the sections b b and o c', as shown in Fig. 5.

The inner closure memberis composed of a sheet of paper similarly subdivided b creasing lines luto sections j,e, f, g and NTTED STATES PATENT OFFICE.

the sections f being further subdivided by diagonal creasing` lines 5. This blank or sheet may be folded in a simple manner to produce a cup shaped cap, as shown in Fig. 3, the walls of which may be inserted into the open end of the. receptacle as formed from the blank shown in Fi is adapted to be inserted wit 7L overlappin the upper margins of the receptacle, an folding over the members j thereof, whereby the members la,

the members or project downwardly along the outer surfaces of the respective members a.

The cover member of the closure is formed from the blank shown in Fig. 8,*.said blank 6. This cap A p are perbeing creased along substantially the same lines as the blank illustrated in Fig. 7 and forming a series of sections j', e', 'g' and h', but said sections h are folded inwardly instead of outwardly, thus forming the rectan- ,gular'cover shown 1n Fig. il.v This closure i l. A liquid holding rectangular paper receptacle having side and bottom' walls formed integrally from a single blank provided with inwardly folding diagonally formed integral y creased corner portions lapped upon each other and reversely folded upon the inner faces of the side walls of the receptacle.

2. A liquid holding rectangular paper receptacle havin side and bottom walls vided with inwardly folding diagonally creased corner portions lapped upon each other and reversely folded upon the inner faces of the side walls of the rece tacle, said side walls being provided with aps folded inwardly and downwardly over the reversely folded portions.
