CLOSURE CAP.

Application filed September 24, 1926. Serial No. 137,543.

The present invention relatesto a closure cap, being more especially adapted foruse on milk bottles, or the like, and aims to provide a novel and improved cap of this character which can be conveniently and efiiciently removed from a bottle, or like container, without danger of spilling the contents in the container.

Another object of the invention is to provide a closure cap constructed from one piece of relatively thin cardboard or similar material, having the marginal edge thereof turned over and pressed down on the body of the cap to reinforce the same at the periphery thereof and to provide finger engaging portions for removing the cap from the bottle, or like container.

It is also an object of the invention to provide a cap of the above indicated character, which is extremely simple and substantial in construction, which can be manufactured economically, and which will be thoroughly efiicient and practical in use.

With the foregoing and other objects in F View, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and clalmed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a top plan of my improved cap, 7

Figure 2 is a cross section taken on line 22 of Figure 1, and

Figure 3 is a view similar to Figure 2, showing the cap arranged for closing the mouth of a milk bottle.

In carrying out my invention, the numeral 10 designates a piece of cardboard which is relatively thin. The piece of cardboard when cut or stamped out is of circular formation and has the marginal edge thereof turned over and pressed down in close contact with the body of the cap, as at 11. When turning the marginal edge of the cardboard over and pressing the same down, pleats 12 are provided. The pleats extend inwardly of the cap approximately onesixth of the diameter thereof, which will reinforce the relatively thin cardboard at the periphery of the cap so that the periphery of the capwill snugly engage a bottle or llke closure when arranged thereon. The marginal edge of the blank piece of cardboard from which the caps are constructed 1S turned over the same distance from the edge of the cap entirely around the same so that said turned over portion extends inwardly toward the center of the cap a like distance entirely around same.

The purpose of turning over the edge of v the cap is not only for reinforcing the same at the point where the cap contacts with the neck of a bottle, or like container, but is also for the purpose of providing finger engaging portions in order that the cap may be easil' and efficiently removed from a bottle, or 11 e container, without danger of splashing or spilling the contents in the bottle,

or like container.

By constructing my improved cap in this manner, it is to be noted that caps can be constructed from material relatively thinner than that now commonly used, as the turnlng over of the edge of the cap will reinforce the same and provide sufficient friction at the neck of the bottle, or like container. Caps are commonly sold according to weight. Thus the Weight of one of my improved caps would be approximately one-quarter less the weight than caps now used.

-When it is desired to remove oneof my improved caps from the neck of a milk bottle, or like container, the person removing the cap engages one of the pleated portions of the turned over portion 11 between the index finger and the thumb of one of his hands so as to obtain sufiicient gripping thereof in order to overcome frictional engagement of the cap with the bottle. By then pulling on the turned over portion, the cap may be easily and eificiently removed. It is to be noted that the point where the turned over portions are provided is at the point where the cap engages the bottle, and at a point where the contents of the bottle hardly contacts with the cap to moisten the same and loosen the fibers in the cardboard, which would tend to permit easy tearing or pulling ofthe finger engaging portion from the body of the cap. Furthermore, all

of the pleats are attached together so that pull upon one of said pleats will be transmitted to the pleats adjacent thereto, thus also eliminating the tendency oi the pleat being engaged from being torn from the body of the cap during removal of the cap.

Having thus described my invention, what I claim as new is:

1. A closure cap constructed of one piece of sheet material of circular formation and having the portion adjacent the periphery thereof turned over on the body portion so as to increase the thickness of said cap at the horizontal circular marginal edge thereof.

' 2. A closure cap contructed of sheet matepleats forming finger engaging portions for I removing the cap.

3. A closure cap constructed of one piece of material and having the marginal edge turned over on itself and pleated for reinforcing the marginal edge of the cap that engages the cap groove of a bottle.

In testimony whereof, I have afiixed my signature.

SEVERIN WVESTBY.
