Application November 7,1932, 'Serial No. 641,621'

Claims.

This invention relates to non-refillable containers such as cans used to transport, store and dispense high grade oils.

An object is to provide a strong, durable and inexpensive sealing device which will render high grade oil cans pilier proof.

A further object is to provide acan having a valve controlled pipe through which the contents of the can may be pumped and which is locked fast to the can head by novel locking fingers'carried'by a sleeve integral with thehead and which lodge against a shoulder formed on the pipe.

With the above and other objects in view the invention consists in certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any 6 of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a vertical section through an oil can equipped with my invention,

Figure 2 is an enlarged detail section of the pipe and its connections with the can head, and

Figure 3 is a cross section taken on the line 3-3 of Figure 2.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, designates a container which may be of any type but which for the purpose of one example of the application of the invention, is shown as a metal can or barrel of the usual and well known type used to store, ship and dispense lubricating oils.

In carrying out the invention I provide in the can head 11 a countersunk seat 12 the wall 13 of which is preferably of octagon shape, as shown in Figure 3, and the bottom of which is annular in contour to provide a ledge 14. The seat is formed with a downwardly extending annuler skirt 15 at the inner end of the ledge and the skirt terminates in a bottom closure 16 which slopes downwardly, as shown. A sleeve 1'? is formed integral with the bottom closure 16 and is of sufficient diameter to snugly receive a suction pipe 18 through which the contents of the can may be pumped. The sleeve is provided with pairs of slits at preferably three points around the circumference and the metal between each pair of slits is bent outwardly and thence terminally bent inwardly to provide a spring dog 19. There are three of these dogs preferably disposed around the circumference of the sleeve. Preferably the head 11 of the -c an is fabricated with the above described seat ,12, skirt 15, bottom closure 16 sleeve 17 and spring dogs 19. v r

A reducer 20, having a-flange'21 corresponding to the shape of the seat 12 isforced snugly into said seat until the flange rests upon the ledge 14. The shape of the wall 13 of the seat and of the flange 21 of the reducer preventrotati'on ofthe reducer so that when once applied ,it is permanently mounted as an integral part'of the can head. The reducer is provided with screw threads 22. Y

A plug nut 23 of standard type is threaded into the reducer toseal the can and preferablya gasket 24 isapplied between the flange of the plug nut and the flange 22 of thereducer to seal the can and render it leak proof.

In further carrying out the invention the pipe 18 is provided at the top with an outwardly extending flange 25 which terminates at the edge in a rib 26. The flange and rib are adapted to compress a washer 2'7 of packing material against the sloping bottom closure 16 of the can head and seal the pipe leak proof to the can head. Below the flange 25 and at such a distance as to receive the bent ends of the spring dogs 19, the pipe is bent inwardly to provide a shoulder 23 and above the shoulder is tapered so that the pipe presents a substantially inverted frusto-conical wall 29 above said shoulder. This wall provides suflicient room for the extreme ends of the spring dogs to accurately rest upon the shoulder. It will be consequently observed that any surreptitious attempt to withdraw the pipe 18 from the can head will be frustrated by the shoulder 28 and spring dogs 19 which coact in preventing retrograde movement of the pipe out of the. can head while freely permitting entry of the pipe through the v sleeve 17 during assembly of the pipe with the can head.

A ball check valve 30 is mounted on a perforated seat 31 disposed in the bottom of the pipe 18. A helical spring 32 is seated on the ball and bears at the top end against an annular abutment 33 formed by constricting the pipe wall, as shown. As usual the ball lifts during suction of a pump applied to the reducer 20 after removal of the plug nut 23 and permits the contents of the can to be dispensed. However, any attempt to refill the can through the pipe will be frustrated by seating of the -projecting downwardly therefrom,

From the above description it is thought that the construction and operation of my invention will be fully understood without further explanation.

What is claimed is:

1. The combination with a container having a head, of an angular depression in the head forming a seat, a sleeve carried by said seat, a reducer having an angular portion fitted in said seat, a spring dog carried by said sleeve, and a check valve controlled pipe in said sleeve disposed concentric with the reducer and having an annular shoulder against which said dog lodges and prevents removal of the pipe through the reducer.

2. The combination with a container having a head, of a sleeve integral with the head and a check valve controlled pipe disposed in the sleeve and terminating at the top in a flange, a gasket on the'pipe between the flange and the sleeve, 'a spring'dog carried by the sleeve, and an annular' shoulder carried by the pipe seating the spring dog and preventing removal of the pipe from the container head. f3. ,Ina container, a head having a. seat provided with an angular wall and ledge, a skirt extendingdownward from'the ledge, a sleeve carried 'by and disposed concentric with the skirt, a spring dog on the sleeve, an interiorly threaded reducer fitting snugly in said skirt and having an angular flange fitting snugly against .the angular wall of said seat, a check valve controlled pipe within the sleeve, and an annular shoulder on said pipe receiving said dog and pre venting removal of the pipe-from said sleeve.

4. In a container, a head having a seat provided with an angular wall and a ledge, a skirt extending downward from the ledge, a downwardly sloping closure extending from the bottom of the skirt, a sleeve extending downward from the closure and having a spaced pair of slits, the material between the slits being bent outwardly and terminally bent inwardly to providea spring dog, a reducer having an vangular flange seated on said ledge and snugly engaging the angular wall of the seat, a plug nut threaded into said reducer, a check valve controlled pipe disposed concentric in the sleeve and terminating at the top in a flange disposed below the bottom of said nut, and a packing gasket confined beteween the flange and said bottom closure, the wall of the pipe being directed inwardly to provide an annular shoulder receiving the bent end of said dog and preventing removal of the pipe from the sleeve, the wall of the pipe above the shoulder being substantially inverted frusto-cOnical inshape to provide sufiicient room. for the, dog to tightly engage said seat.

5. The combination with a container having 100 a head, of a check valve controlled pipe depending from the head and having a portion thereof bent inwardly to form a stop shoulder,

a sleeve depending from the head and fitting snugly around the upper end of the pipe, said 105 sleeve being provided'with spaced incisions defining intermediate spring dogs having inwardly directed terminals adapted to bear against the shoulder and lock the pipe against removal from the container. 110
