BOTTLE AND BOTTLE CAP.

Application filed May 17,

This invention relates to bottles of the type adapted to be closed by the application of a flexible disk cap to a recess provided in the neck of the bottle to form a seat for the cap.

The ordinary milk bottle is a highly standardized device, having the inside edge of the neck thereof recessed to receive a thin flexible closure disk or cap. This cap is com monly made of cardboard, and, unless provided with costly opening lugs or tabs is difficult to remove from the bottle. Plain caps must usually be pushed in-on'the contents of the bottle to open the bottle; and this operation, whether eflected by hand or by use of a sharp pointed tool usually causes some of the contents of the bottle to be spilled and wasted, and frequently splashes the contents on to the person opening the bottle.

The main object of the present invention is to provide a milk bottle of standard type having the cap seating finish thereof slightly modified to provide for ready removal of the cap without necessitating the use of costly tabs or the employment of sharp pointed tools.

Another object of the invention is to provide bottles of this type with a cap of stand ard size which effects ready sealing of the bottle and which can be readily removed by applying the finger nail of the user to rotate the cap.

A further object of the invention is to form the necks of these improved bottles so as to adapt them for use with standard capping machines and with standard caps, and formed so as to eliminate sharp edges which would be liable to be chipped by the capping inachines.

Still another object of the invention is to form the cap raising parts of the bottle neck so as to cause one edge of the cap to rise faster than the diametrically opposite edge when the cap is being rotated to effect its removal. Other objects of the invention will become apparent as the detailed description thereof proceeds.

ferred form ofcap adapted'for use With this bottle.

Figure 6 is a section on line 66 of Figure 5.

The drawings show the neck 1 of a milk bottle, standard externally in every respect. The top edge 2 of the roll 3 is unbroken throughout its inner and outer peripheries; and the inner surface of the neck 1 is pro- .vided with a finish of standard type having the usual recess face 4'and shoulder seat 5.

At diametrically opposite parts the face 4 is provided with substantially V-shaped recesses 6 and 7. Each. of said recesses is about one-thirty-second of an inch deep where it meets the shoulder 5, and its inclined edges decrease in depth until they vanish imme diately below the line wherethe roll of the bottle neck begins. For example, the in clined shoulders 8 and 9 of recess 6 are each about one thirty second of an inch deep at the point 10 where theymeet shoulder 5; but decrease in depth as they rise to a vanishing point on the imaginary line 11 where the roll of top edge 2 begins. This construct-ion presents smooth edges to the capping machines, and practically eliminates all chance of chip ping the bottle neck during the capping operation.

The recess 7 has its shoulders 12 and 13 in clined at a sharper angle to each other than are the shoulders 8 and 9 of the recess 6. This arrangement is provided to cause the side of the cap 14 in contact with the walls of recess 7 to rise'more rapidly than the diametrically opposite side in order that the cap may tilt as it rises to'clear the line 12 where the recesses begin, and more readily effect removal of the cap.

The cap 14 may be the ordinary standard cap commonly used in standard bottles. I prefer, however, to useone of standard size and thickness provided with diametrically opposite indents 15 and 16 or projections 17 and 18 adapted to be engaged by the fingers of a person desiring to open the bottle by merely rotating the cap on its shoulder seat 5.

I prefer also to provide the cap 14 with an annular groove 19 to permit the cap to find a proper bevelseat on the shoulder 5 which in standard bottles is usually down wardly and inwardly inclined with all its edges and corners rounded. I

I also prefer to mill the edge of the cap 14 in order that the cap edge may yield slightly where it contacts the unbroken face 4 of the finish and thereby may allow the parts and 21 to project into the recesses 6 and 7 and form lugs adapted to ride up on the inclined edges of the recesses 6 and 7 when the cap is rotated in either direction to remove it from the bottle neck. I

It will be apparent from the description so far that I have provided a milk bottle stand ard as to size and adapted to be operated upon-by a standard cappingmachine to apply standard caps thereto. The very slight shouldered recesses (Sand 7 can be very readily formed without involving any great change inthe bottle moulds and without effecting any change whatever in the standard roll of the common milkbottle neck.

It will also be apparent thatthe caps described herein may be readily removed without pressing it inwardly on the contents of the bottle and by mere rotation will be caused to ride up on the inclined edges of the recesses 6 and 7 without danger of spilling the contents of the bottle.

lVhile I have shown the bottle as provided with only two ofthese recesses, it must be understood that this invention is not to be limited as to the number thereof. It must also be understood that while I have shown and described the diametrically opposite re- ,cesses as having shoulders of different-inclinations that identical recesses may be used.

7 It will also be understood that the invention is not limited to use with the particular caps shown anddescribed herein and that the bottle disclosed herein is designed for use with standards caps of any ordinary or desired construction.

What I claim is:

1. A bottle having a shoulder in the neck thereof, a cap seated on said shoulder, and cooperating means formed on said neck and cap to raise the cap on said shoulder by rotation of the cap in either direction.

2. A'bottle having a shoulder in the neck thereof, a flexible capseated on said shoulder, and cooperating means formed on said neck and cap to raise by rotation of the cap in eitliei direct on.

- 8. A bottle neck having a shoulder formed below the top edge thereof and having a recess formed therein and extending from said shoulder toward said edge, a flexible cap seated on said shoulder and having a part thereof projecting into said recess, said recess having oppositely inclined shoulders adapted to engage said part and raise the cap from said shoulder by rotationof the-cap in either direction.

a A bottle having a shoulder in the neck thereof, .and'having diametrically opposite 'V-shaped recesses formed therein and extending from said shoulder toward the top edge of :said neck, a

flexiblecap seated on said shoulthe cap from said shoulder 'tated in either direction to raise the cap from said shoulder.

5. A bottle having a shoulder in the neck thereof and having diametrically opposite V-shaped recesses formed therein and flaring upwardly toward the top edge of said neck, a flexible cap seated on said shoulder and having diametrically opposite parts projecting into said recesses and adapted to engage the edges thereof when the cap is rotated in eitherdirection to raise the cap from said shoulder, and means on said cap to rotate the cap in either direction. j

6. A bottle having a shoulder in the neck thereof, a flexible cap seated on said shoulder and being provided with an annular groove to cause upward tilting of the edge of said cap when seated on said shoulder, means on said cap adapted to be manually operated to rotate said cap, and cooperating means formed on said cap andbottle neck to effect the removal of said cap from said neck by rotation of the cap.

7. A bottle having a shoulder in the neck thereof, a flexible cap seated on said shoulder and being provided with an annular groove to cause upward tilting of the edge of said cap when seated on said shoulder, means on said cap adapted to be manually operated to rotate said cap, and cooperating means formed on said cap and bottle neck to effect the removal of said cap from said neck byrotation of the cap in either direction.

8. A milk bottle, having a neck provided with a standard roll and with a shoulder below the rolled edge thereof, the inner periphery of said neck being provided with V-shaped recesses having sides thereof flaring upwardly from said shoulder toward said edge and decreasing in depth from said shoulder to a vanishing point at the beginning of the roll of said edge, a flexible cap seated on said shoulder and having projections extending into said recesses, and means on said cap for rotating said cap to cause said projections to ride up on said side when the cap is rotated in either direction.
