NEW JERSEY HONADULTERABLE CONTAINER Application an December 7, i928. se ial No. seams.

This invention relates to non-adulterable' Y containers.

in the oil industry lubricating oil in higher grades of Such it is customar'z to ship drums and in tha case oi oil the bungs are sealed. protection is only efiicacious during shipment as the service man is obliged to open a hung to insert his oil pump. '(lonsiderable money has been spent to educate it the public to the use of the better" grades of vention is to provide lilti oil but avaricious and unscrupulous garage and service station men are substituting inferior oils by refilling drums that originally contained the better grades of oil and which have the trademark or other indicia of the shipment purposes better gradesthereon. c

@ne of the objections of this invention is toprovide a drum, the contents of which cannot be adulterated. or refilled by the garage or service men without indicating such facts. Still another object of the inwherein only the bung requires a change from the usual form of drum. Still another object of the invention is to provide a nonadulterable drum wherein the usual form of delivery pump may be used. A still further object of the invention is to means to prevent the adulteration of tents of a drum which relatively low cost.

Referring to the drawings 2 Figure 1 is a view "in elevation partly in section showing a pump in connection with the device. I

Figure 2 is a View in longitudinal section of a device embodying the principles of my invention.

Figure 3 is a sectional view along the line the conmeans shall be of 3, 3, of Figure 2, looking in the direction or crimped within and to the cylindrical side walls at each end.

My device can be utilized with any of the commercial drums.

In carrying out my invention the usual drum 1 has the customary bu'nghole 2" in.

a non-adulterable drum provide 22.

threaded or welded or otherwise secured within the bung hole. Cylindrical collar 21 which forms the securing means of bung 4 is adapted to receive wbll 8. wen 8 may be of metal tubing or other suitable material. A'washer 20 of cork or other suitable materialis located between the end of tubing 8 and the underside of bung a to provide and air tight connection and to permit of more tightly securing of bun 4 where it is threaded into the bung ho e. A. screw threaded hole 6 in bung 4 communicates with the interior of well 8 and the atmosphere. Plug 6' is adapted to fit therein for L and l propose to provide a seal 7 which may be secured to cap 6 and bungto prevent tampering in shipment. Bung 4 is likewise sealed to the head of drum 1 by seal 5 to prevent tamperin while the drum. is on service. Although have shown one form of sealing yet my invention is adapted to utilize any of the well known forms oi bung sealing means.

Within well 8 ll provide guard .18 having holes 19 and secured by any well known means to the walls of well 8 such as by screws Below guard 18 I provide spacing shield and strainer 16. Below strainer 16 is valve seat 12 and valve 14. Valve 14 is preferably a mushroom or poppet valve with seating spring 15. Valve seat and supports valve 14. The lower portion of tube 8 has cut out flaps 9 which are bent in to permit the oil to flow into the bottom part of well 8 and to prevent valve 14 from being.

forced down from above. In the event of the forcing down by breaking down guard Y18 and crushing of spacing strainer 16 with ing the tubing to the bottom of the drum to 12 guides the stem prevent breakage or displacement of, well 8 from bung 4 due to the movement of the oil in shipment. The form shown is ring 10 having feet 11 which may be. welded to the drum head.

In operation drum 1 is filled in the usual way at the refinery and well 8 is likewise filled. Cap 6 is inserted and the seals 5 and 7 are secured and the drum is ready then for shipment. Upon receipt by the garage or service station man ca 6 is removed and pump 2 is screwed into ung 4. A washer 23 x should be used as shown in Figure 1 to give an air-tight connection. The pump is now ready to deliver. As the oil is withdrawn from well 8 by pump 2 valve 14 opens permitting the-withdrawal of'oil as replacement in well 8. Valve 14 opens and closes with each stroke of the pump and is normally closed. Q What I claim is:

1, A container, an opening in said container, a ring in said opening, a tubular well secured to said ring, a packing ring between the end of said well'and said ring, said ring adapted to rec'eive a shipping cap and a pump, said well adapted to receive the shaft of a pump, openings in the bottom of the walls of said well, said openings formed by bent in cutout tongues, a-valve seat secured in said well by said bent intongues, a valve supported and guided by said valve seat, a spring to normally maintain. said valve closed, a spacer and strainer above said valve and secured "te the walls of said well,

i 2, A container comprising a drum having two heads, a hung opening one said heads, a hang for said hung opening, said bung adapted. to receive on its underside a tubing forming a well, a gasketbetvveen the end of said tubing and said bung, a threaded opening in said bung adapted to receive shipping cap and a pump, means for sealing said bung to said drum head, means :ier seal ing said. shipping cap to said bun the walls oi said well at the lower end having tongues cutout and. bent in to permit ingress the contents of said container into said vveil to suppsrt a valve seat in said. w'eli, a valve seat in said Well, a valve for said valve seat,

a spring to maintain said valve against its seat except when the contents of said well are removed by a pump therein, a spacer and strainer above said valve, a gnarc'i abeve said spaces and strainer, means :t'or securing said guard to the walls of said well,
