11 Claims. 1
This invention relates to improvements in paper bottles and the like, and method of manufacture.
The main objects of this invention are:
First, to provide a paper bottle or container well adapted for use as a milk bottle which may be formed entirely of paper stock and is well adapted to receive and retain a closure of the disk type.
Second, to provide a container having these advantages which may be formed of relatively ligh, stock and at the same time is strong and r1g1 Third, to provide a structure having these advantages which is economical to produce.
Fourth, to provide a method of manufacturing containers of the type described which enables very large production by machinery.
The accompanying drawings illustrate both the steps of manufacture and the completed container.

In the accompanying drawings the invention is illustrated as it has been embodied and practiced in the manufacture of milk bottles, although it will be understood that the container of this invention is adapted for a wide variety of uses.
The conical tubular body or wall member I is formed of a suitable blank 2 having adhesive 3 applied to one edge thereof, the edges of the blank being brought together into lapping relation and sealed throughout. For some purposes a thermoplastic adhesive may be desirable. After forming the blank the next step in the method is the forming of the flange 4 on the upper end thereof.
In production it is preferable to employ a suitable conveyor having a series of tubular conical mandrels 5 thereon, these mandrels having an internally cylindrical portion 6 at their upper ends. The mandrel also constitutes a die memher, as will be pointed out. The mandrels are of such size as to effectively support the wall or body members and the sleeves thereon with their upper ends projecting above the mandrels.
The flange 4 is formed by turning the same outwardly as by means of the forming member or die member I having an annular curved recess 8 at its lower end. However, the flange may be formed by a rolling or spinning operation, a spinning member 9 being shown in Fig. 10.
After the flange is formed an adhesive sealing material is applied thereto and the cup-shaped top member I!) formed of suitable paper or fibrous stock is inserted therein as shown in Fig. 11, with the end of the mandrel in supporting relation to the top member below its cylindrical side walls. In this position the top member projects above the flange on the body member. The forming member H is then actuated, this forming memher having a reduced tip portion I2 adapted to enter and supportingly fit within the wall of the top member and an annular downwardly facing curved channel I3 which gradually crimps or turns the projecting edge of the top member around the flange 4 into clamping retaining engagement therewith. The flange is also curved during this operation as shown in Fig. 13. This step is performed before the adhesive sealing material has set and it spreads and brings the adhesive material into thoroughly complete sealing and adhering relation to these two parts.
Associated with the forming member is a punch aaoaess M which is actuated in timed relation to the actuation of the forming member so that after the forming member is completely actuated the punch is actuated to punch out the central portion l5 of the top member. The top member is effectively clamped in position during this punching operation so that it is not distorted. As stated, the mandrel performs the double function of a mandrel and female die member. This operation forms a supporting ledge or flange M5 for a disk-like type of closure ll as shown in Fig, 13.
It will be noted that there is a slight space or clearance shown at I8 in Fig. 13 between the cylindrical side portion of the top member and the conical wall of the container which permits some springing or expanding of the top member adjacent the closure supporting seat thereof when the closure disk is forced or pushed into position. I have not attempted to illustrate this springing action as it would be relatively slight where all parts are made in proper proportion, but it is of decided advantage in the effective retaining of the closure and in accommodating closures varying in diameter.
After the top member has been applied to the wall the bottom 28 is applied. This is formed from a disk I9 of fibrous material, see Fig. 15. A flange 20 is formed on the disk and the bottom thus formed is inserted in the lower end of the container. The bottom wall is then crimped or folded around the flange 28 as shown at 2%. Adhesive is preferably used at the joint in this operation. The means for applying the bottom are not illustrated as suitable mechanisms for performing this operation are known in the art.
Suitable waterproofing may be applied if desired, paraffin being quite commonly used.
The method of this invention can be very economically practiced, that is, a fairly simple machine may be used with substantial and uniform production. The container is strong and rigid, the top member effectively reinforcing the wall or body member as well as providing a suitable rim and a closure seat. The structure illustrated is designed as a milk bottle or like container of the conical type, but it will be understood that other forms of containers or closures may be made, and containers adapted for various uses. It is believed that the disclosure made will enable those skilled in the art to embody or practice the invention as may be desired.

The method of making containers of fibrous material adapted to receive a closure disk comprising the steps of forming a tubular conical wall of fibrous material with an out-turned flange on the upper edge thereof, applying an adhesive sealing material to said flange, disposing a top member of fibrous material having a cylindrical side wall in the upper end of said container wall with a portion of the top member side wall projecting above said wall flange, crimping the projecting portion of the side wall of the top member around the flange on said wall prior to the drying of the adhesive sealing material, said top member being provided with an annular closure seat at its inner end, the cylindrical wall of the top member being spaced from the conical wall of the container to provide an annular space between the cylindrical wall of said top member and the conical wall of the container for permitting expansion of the inner end of the topmember when a closure is pressed therein, and supporting said top member against inward thrust during the crimping operation, the supporting of the top member being by supportingly engaging the bottom thereof independently of and within said tubular wall.
10. A container of fibrous material adapted to receive a closure disk comprising a tubular wall member of fibrous material having an out-turned flange at its upper end, an annular top member of fibrous material disposed within the upper end of said wall member, said top member being crimped around said flange into closely embracing relation thereto, there being adhesive and sealing material between said flange and said top member, said top member having an opening through its inner end surrounded by an annular flange constituting a closure seat, the lower end portion of the side Wall of said top member being spaced from said tubular wall to provide expansibility of the top member relative to the container wall when a disk-like closure of predetermined diameter is disposed therein.
11. A container of fibrou material adapted to receive a closure disk comprising a conical wall member of fibrous material having an out-turned flange at its upper end, an annular top member of fibrous material disposed within the upper end of said wall member, said top member being crimped around said flange into closely embracing relation thereto, said top member having an opening through its inner end surrounded by an annular flange constituting a closure seat, the side wall of said top member being cylindrical to provide an annular space between the lower end thereof and the conical wall to permit expansibility of the top member relative to the container wall when a disk-like closure of predetermined diameter is disposed therein.
