JESSE H. IEERRAULT, or DETROIT, MICHIGAN.

PAEERBQTTLE AND OPENER.

Specification of Letters Patent.

Patented May "2, 1918.

Application filed January 19, 1916. Serial No. 73,004.

To all whom it may concern 1 Be it known that I, JEssE H. PERRAULT, citizen of the United States, residing at Detroit, Wayne county, Michigan, have invented certain new and useful Improvements in PaperBottles and Openers, of which the following is a specification.

- This invention relates to improvements in paper bottles or receptacles, and particularly to an improved means for readily opening or removing the caps therefrom.

The objects of this invention are:

First, to provide an efiective and-simple means for severing the wall of a paper receptacle.

Second, to provide a form and arrangement of structures whereby the result of severing or separating a part may be readily accomplished.

Further objects and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means describedin the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I milk bottle embodying the features of my invention in a preferred form.

Fig. II is an enlarged detail vertical sectional view taken on a line corresponding to line 22 in Fig. I.

Fig. III is a detail sectional view taken on a line corresponding to line 3-3 of Fig. II, showing the formation and folding of the layers and the disposition of the severing cord therein.

Fig. IV is a detail elevation view of my invention applied to a tapered cup structure.

-Fig. V is adetail sectional view taken on a line corresponding to line 5-5 of Fig. IV, showing the arrangement of the parts and the disposition of the severing cord therein.

Fig. VI is a detail sectional view taken on a line corresponding to line 66 of Fig. V.

Fig. VII the layers of paper are folded back upon themselves to form the upper edge of the receptacle. I

Fig. VIII is a detail sectional view showing my invention as applied to the straight 1 sides of a paper receptacle made up of sevis an elevation View of a papershows a modification in which' the separate drawing, 1 is the body of a milk bottle or other jar made up of plies of paper 2, the

which are preferably disposed transverse. 3 is the neck conformed by creasing and folding the paper together. 4 is the annular crease in the neck conformed at the inner side in angular form to receive the cap 5. All of the layers of paper are conformed to this crease (the crease being preferably formed by dies after the bottle is made) and within the crease is disposed a waxed or oiled cord 6 which is securely retained between the layers of paper with the outer end projecting. When it is desired to remove the cap, as seen in Figs. I, II and III, the projecting endof the cord is grasped by the user and it is simply unwound, and because it does not adhere to the paper it readily cuts the wall ply by plyand severs the top, permitting the cap to drop freely without any necessity for punching or pulling of the parts. This presents a perfectly clean-cut pouring surface for the contents of the bottle, which is perfectly fresh cut and uncontaminated.

The thread being folded between the layers and assed around in the creases, as indicated in Fig. III, is sufficiently retained so that its cutting action is very pronounced, and it readily severs the top as indicated. This can be applied to straight side jars, preferably creased, where the convolutions of the folded parts are absent, as seen in Figs. IV and V. The action of the cor is greatly facilitated by conforming the annular groove with a sharp angular projection.

In Fig. V there are two layers 7 of the material and the cord 6 is disposed between the same in' precisely the same manner as appears in Fig. II, except there are no convolutions of layers.

In Fig. VII the cord is only disposed between the outer layers 8, the outer ply being folded back on itself at the top at 9, and the fibers of severed part is simply held to the outer I layers by a thin layer of parafiin. It is ver readily separated when the outer layers have been cut by the cord.

With the straight walls seen in Fig. VIII, made up of layers 10 with a cap 11,-it is necessary to dispose the cord in the concentric layers in substantially the same plane,

so that it will only be necessary to draw the cord through a single layer of material at a time. It is less easy to effecti ely locate the cord in this structure, but it can be accomplished and will do its work, but not nearly so well as when disposed in the creases indicated in the other figures of the drawing.

These paper bottles and receptacles are parafiined and 4 the layers are retained together in part by the paraffin, and the effect of the same on the plies of paper is to make them very readily severable by the waxed or oiled cord.

The disposition of the fibers transverse to the neck 01' body of the receptacle facilitates the action of the cord, which is then a splitting action as distinguished from a transverse cut. This is of high consequence where the cord is made use of in such modifications as special groove has not been formed, although it is of advantage where the groove has been formed where the cord then operates with the greatest facility. Of course it is of less importance that the cord be specially waxed where it is disposed in the angular groove.

I have shown my invention in the form preferred by me, but I am aware that it is capable of considerable variation without departing from the spirit of my invention,

and I desire to claim the same specifically in the form illustrated, as well as broadly within the scope of the appended claims.

Having thus described my invention,.what I claim as new and desire to secure by Letters Patent is 1. A receptacle made up of layers of paraflined paper, with annular grooves formed therein with waxed cord disposed between the layers in the angular projections with a projecting end whereby the same may be withdrawn severing the successive layers for opening the receptacle, the annular groove.

2. A receptacle made up of layers of paraflined paper, with annular grooves formed therein with angular projections,

ers in angular projections With a projecting same may be withdrawn severing the successive layers for opening the receptacle.

3. A receptacle made up of layers of 7 paper, with annular grooves formed therein appear in Fig. VIII, where a' angular projections, a.

and a cap retained withinv with angular projections, a waxed cord disposed between the layers in the angular projections with a projecting end whereby the same may be withdrawn severing the successive layers for opening the receptacle, and a cap retained within the annular groove.

4. A receptacle made up of layers of paper with the fibers disposed transersely to the receptacle, with annular grooves formed therein with angular projections, a cord disposed between the layers in the angular projections with a projecting end whereby the same may be Withdrawn severing the successive layers for opening the receptacle, and a cap retained within the annular groove.

5. A receptacle made up of layers of paper,with annular grooves formed therein with angular projections, and a waxedcord disposed between the layers in angular projections with a projecting end same may be withdrawn severing the successive layers for opening the receptacle.

6. A paper receptacle made up of layers of paper with the fibers disposed transversely to the receptacleconformed and folded the one upon the other, and a cord disposed in between the successive layers in the same region, with a projecting end for cutting and severing the successive layers for opening the receptacle.

7. A receptacle made up of layers of paper with the fibers disposed transversely to the receptacle, with annular grooves formed therein with angular projections, a cord disposed between thelayers in the angular projections ith a projecting end whereby the same may be withdrawn severing the successive layers for opening the receptacle, and a cap retained within the annular groove.
