JAMES F. EINFELDT, SAN FRANCISCO, CALIFORNIA;

MILK-BOTTLE-GAP REMOVE-R. 7

Specification of Letters Patent. 7

Application filed March 12, 1918. Serial No. 221,887.

To all whom it may concern Be it known that I, JAMES F. EINFELDT, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Milk-Bottle-Cap Removers, cation.

This invention relates to a means for removing the normal closures from milk containing bottles and the like; and has for its object to lift the cap bodily from its seat and to retain it in such a position as to be easily replaced and released.

It consists of a preferably convex disk of such a diameter that it may be introduced into the sunken seat, above the normal closing cap upon which its periphery rests. Within the convexity is an elastic curved arm, having apointed end, and means for turning and advancing the arm so that the point will pierce the material of the closure approximately parallel with the surface. i inclined slot is made through the side of the cap and the operating arm projects through this slot so that by its aid the interior pointed arm will be pressed down by the inclined travel and will thus be forced into the material of the receptacle closure in such a manner that the lifting of the utensil, by means of a suitable handle, will bring with it the closure which is held closely against the remover, and may be replaced by it, and afterward released so as to remain upon its seat.

In the accompanying drawings:

Figure l is a vertical section.

Fig. 2 is a bottom view of the utensil.

ig. 3 is a modified form.

Milk and like containers usually have wide mouths and an interior flange or shoulder upon which the circular closure rests, fitting closely enough to maintain its place and prevent the escape of the contents. These closures are usually made of some fibrous, flexible material, like pasteboard, and after being seated are difiicult to remove without being destroyed and splashing some of the contents.

In the present invention a centrally journaled arm A, having a curved portion 2 at the outer end and a sharp terminating point 3, is turnable in a disk-like support 4, the exterior of which is of such a diameter that it will enter the mouth of the container and will rest upon that portion of the closure of which the following is a specifiwhich is supported upon the interior shoulder of the container. The arm 2 being then turned a short distance and being elastic will force the pointed end 3 into the top of the closure, in such a manner that when the disk is lifted itbrings the closure adhering to it.

The elastic action of the arm is making an inclined slot 5 in the of the disk, through which an arm 6 point engage the closure, or retracted to release it.

The form of the disk may be varied. It is here shown as arched, so that the arm 2 may be contained in the concavity. A vertical journal. or equivalent. bearing guides the arm when turned and the projecting arm A extends out through the slot 5, as before described. A central knob or handle 7 serves to its use.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In a milk bottle cap remover, a conaided by periphery operating projects and is so connected with the 3 that the latter may be advanced to guide and hold the disk during Patented Jan. 14,1919. 7

cavo-convex member formed to enter the mouth of the bottle and to seat on the bottle cap, said member having an inclined slot on a side thereof, and an arm journaled at the center of the member and having an operating part extending through the inclined slot and also formed with a terminal point adapted to penetrate the cap upon the arm being moved through the slot.

2. In a milk bottle cap remover, a member formed to overlie the mouth of the bottle and having an inclined guide, and an arm journaled in the member and having a part engaged with the guide and a point adapted to penetrate the cap uponsaid part of the arm being moved to engage the guide and being guided in its movement thereby.

3. In a milk bottle cap remover, a member having an arm movably connected thereto and having a point operating in an inclined plane, and means on'said member to guide the arm whereby to move said point in an inclined plane to cause same to enter the cap.

4. In a milk bottle cap remover, an oscillatory arm, a member supporting the arm,

said arm having a point, and guiding means ling t0 the member,

and when the arm is at the other end of the guide the point will lie above the cap.

5. In a milk bottle'cap remover, a memher having an arm rotatably connected thereto at one end, an inclined point extending outwardly from said arm, and means to operate the arm whereby upon partial turning thereof the point will move downwardly in an inclined plane and penetrate the cap.

6. In a bottle cap remover, a supporting member, a wire and rotatably connected at its point 01": doub said member having a Copies of this patent may be arm doubled upon itseltv obtained for five cents each, by addressing the witnesses.
