PROCESS OF MAKING PAPER BOTTLES.

Specification of Letters Patent. Patented Dec, 30, 1913, Application filed December 1', 1911. Serial No. 663,197.

To all whom it may) concern:

Be it known that I, JOHN R. VA-N Vt'onnnn, a citizen of the United States of America, and resident of Toledo, Lucas county, Ohio, have inventeda certain new and useful Improvement in Processes of Making Paper Bottles, of which the following is a specification.

My invention relates to the manufacture of containers in general but more particularly to containers or receptacles made of paper, and more especially to those that are adaptcd for use as milk bottles.

The object of my invention is to provide a process or method of manufacture whereby a paper blank may be folded and secured together to form a square bottle having a flat bottom and a top with-an opening therein, involving the use of pressure on the inner and outer surfaces of the bottom in gluing.

or otherwise fastening the flaps thereof in place, which internal pressure is exerted over an area greater than the area of said opening, whereby the medium for producing the internal pressure must be capable of expanding after it is introduced into the container through said opening, or at least of contraction to pass "out of said hole, and

whereby a paper milk container is made with a restricted mouth through which parafiin or the like may then be introduced to seal all-- of the cracks and render the bottle capable of use for holding milk or other liquids, the exterior of the bottle being similarly treated to give it a waterproof surface.

The nature and advantages of my improved process will, however, hereinafter more fully appear.

In the accompanying drawings-Figure 1 is aperspective of a paper container or milk bottle of the kind produced by my improved process. Fig. 2 is a perspective of the blank partially folded. Fig. 3 is a detail vertical tle on line 33 in Fig. 5. Fig. 4 shows the blank spread" out flat. Fig. 5yis a section on line '55 in Fig. 3. Fig. 6 is a vertical section of the bottom or lower portion of the bottle on line-6 6 in- Fig. 7. Fig, 7 is a vertical section on line 77 in Fig. 6.

' As thus illustrated, the blank A has'four parallel score lines a,.a', a and a which divide theblank into five

sections

1', 2, 3, 4 and 5. The

sections

1 and 3 have their ends provided with long and short flaps 6, 7, 8,

section 1. The

flaps

10 and 11 are folded inward, and the flaps 6 and 7 are then folded upon each other, thus forming a three-ply top for the bottle, the hole B being cut or punched at the same time, or afterward if desired, and the material being pressed upward to form a raised area around the said hole, as shown in Figs. 1 and 3. This raisingof the top can be done at any time, as,- for example, when the'gluing is done, or when the punching is done, or at a different time. The flaps 8 and 9 are then folded inward, and the

flaps

12 and 13 are then folded upon each other, thus forming a three-ply bottom. Afterward, the bottle thus made is itrlgated inside and out with parafiin or the Now, as the container is to be used as a milk bottle, it is evident that the bottle must be made and fully completed before the contents is'p'oured in or otherwise introduced through the top opening or mouth. vIt becomes aproblem, therefore, how to exert internal weight or pressure suflicient for gluing or otherwise securing the top and bottom flaps together. and this is especially true of the bottom. While the top is being. made, the bottom is entirely open, and it is comparativelv easy to glue-the flaps and punch the hole in practically one and the same operation, or the hole can be made afterward, as the machine has easy access for this purpose through the open bottom of the bottle. Also.-

it is possible to forni the raised area around" 55" the mouth of-the bottle. as access to the interior of the bottle at this t me may be'had' through the bottom .v Withithe bottom, however. the situation isdifl'erent, as when this is made the bottleis closed-except for the opening. B in the top, and this opening is of less area than the area or'extent of internal pressure necessarv on the bottom to produce the desired result; My invention contem plates, therefore, the introduction through the restricted mouth or opening B of a pressure means ormedium which will expand and exert pressure over the inner surface of the bottomio an extent greater than the area of the opening; For this purpose shot or the'like can be used, these small objects being introduced through the said opening and then allowed to expand over the inner surface of the bottom of the bottle. Other medium, such as compressed air, mercury, or even a mechanical device or expanding tool which will open up or enlarge after passing through the said opening, can be used if such is desirable and expedient. Having thus supplied a pressure over the inner surface of the bottom, or over a portion thereof which is of greater area than the opening B, a counter pressure from the outside can now be exerted on the bottom to compress the flaps together with glue or other adhesive between them. After this, the bottle isthen ready for treatment with p'aratfin or the like.

In this way I am enabled to produce a square paper container having a small or restricted mouth and adapted for use as a milk bottle. As the mouth or opening is comparatively small, it is practical and possible to seal it effectively, in any suitable 1 manner, after the bottle has been filled with milk or other liquid. Thus a perfect and inexpensive bottle is made from a single paper blank.

'An important consideration of my improved process is the paraflining of the con- .tainer after it is made and fastened together. In this way a container made from a single folded paper blank, and previously of a character not suitable for holding liquids, is produced for satisfactory use as a milk bottle. The parafli'ning must be internal as well as external, and hence the flaps must all be in place before this part of the process is carried out. The top is, therefore, as explained, made first to provide a permanent opening through which pressure can be introduced to hold the bottom flaps in place while the latter are being glued or otherwise fastened together.

The form of the blank shown economizes the paper, as there. is less waste when the blank is cut with the long flaps at one edge opposite the short flaps at the" other edge. It will also be seen that the shot or other. me-

.dium can be introduced through the bottom quent sealing of the bottle. This punching or cutting is done, of course, while the bottom" is open to afiord access to the interior of the bottle for this purpose. The pressure means for forming the bottom is not introduced into the, bottle until after the top is made and the said opening formed therein.

It is the compression of the three'bottom layers flatwise between the external and in ternal pressure that produces the desired result, which is the last step. Then the bottle with flat sides of one thickness and top and bottom of three thicknesses each is paraffined inside and out in any suitable manner.

What I claim as my invention is:

1. The process of making a container, such as a paper milk bottle having atop provided with a restricted mouth of less area than the bottom of said bottle, which comprises the cutting and folding of the paper to form the sides and mouth of the container, the said top being produced by an operation requiring the introduction and withdrawal of pressure means through the said bottom,

which is still open to afford access to the ining the flaps for the bottom and securing the same together by internal and external pressure thereon, the internal pressure being exerted over an area larger than the area of the said mouth, and then removing the internal pressure through said month.

which is still open to afiord access to the interior of the container for this purpose, folding the flaps for the bottom and securing the same together by internal pressure being exerted over an area larger than the area of the said mouth, removing the internal pressure through said mouth, and then providing the container inside and out with a suitable coating.

"folding the flaps for the bottom and securing the same together by internal and external pressure thereon, the internal pressure being exerted over an area larger than the area of the said mouth, removing the lnternal pressure through said mouth, and
