SPILL-PROOF CONTAINER Filed July 12, 1962 12 mvENToR. Herer Gofds'cm di AT TORNE Y United States Patent O 3,130,5 SPELL-PROUF CGNTAHNER herbert Goldschmidt, 45 Amherst Place, Livingston, NJ. Filed July 12, i962, Ser. No. 209,355 4 Claims. (Cl. 229--2il.5)

My invention relates to spill-proof containers generally, and specically to spill-proof containers having partitions arranged as bellies to prevent the contained material from escaping, regardless of the position in which the container is disposed.

lt is among the objects of my invention to provide a container .that will not accidentally discharge its contents.

Another object of my invention is to provide a container in which the contents are readily accessible to dip brushes.

Still another object of my invention is to provide a container that will keep contaminating material separate.

A further object of my invention is to provide a container whose contents are entrapp-ed in a series of battles, although it may be disposed in several positions other than normal.

These objects and advantages as Well as other objects and advantages may be attained by the device shown by way of illustration in Vthe drawings in which:

FIGURE l is a vertical sectional view of 4a spill-proof container;

FIGURE 2 is a perspective View of a well Ifor the container shown in FIGURE l;

FIGURE 3 is a perspective view of a basket for the container;

FIGURE 4 is a view of a cover-plate for the top of the container;

FIGURE 5 is a perspective View of a truncated cone for the well; and

FIGURE 6 is a side elevational view showing the closure for the container.

The-re are numerous spill-proof containers :for use in industry. The present device features a more positive ability to prevent accidental discharge of the contents despite accidental tipping. Further, lthe container is readily lled, flushed, or cleaned. The impurities that may enter the basket of the container are kept from con- Laminating the remainder of the contents. Bandes, a filter .asset holding contaminating materials from impairing the bulk of the contents, and a trap-door accomplish these objects.

Referring now to the drawings in detail, the spill-proof container comprises a housing 1l. The housing l1 is generaliy rectangular in horizontal cross-section, and closed lat the bottom l2. The central portion of the bottom has a generally :circular depression 13 that is dimensioned to receive the .bottom of a well i4. The top of the housing 1l is open so that the well M can be inserted. The well i4 is preferably circular, and it rests in the depression t3. The well le extends toward the top of the housing itl, but it terminates below it. The well 14 has a radial flange 15 at its top edge that extends to the inside of the wall of the housing, where it serves as a closure, below the level of the top of the housing 11. The ange 15 has an upturned edge lib. The bottom of the Well 14 ihas a lbottom feed tube lo connected to it and extending outwardly and horizontally toward the corner of the housing `11 adjacent to a fller port. Fluid outside the Well .le may enter the well 1d through the feed tube i6. The well 145 also has an air relief tube 17 communicating with its interior immediately above the -feed tube 16 and extending toward the corner of the housing adjacent to ya filler por-t. The air relief tube i7 extends in a generally upward and out- Ward direction toward the flange 15 and terminates near the edge thereof and adjacent to the corner of the container ll. The feed tube 16 and the air relief tube 17 preferably lie in the same vertical plane, the one above the other, and extend toward a corner adjacent to a filter post, otherwise air would be trapped when the container is on its side for filling.

A perforated basket .18 lies in the bottom of the well 14. The basket 1S is lesser in external diameter than the internal diameter of the Well i4. It is provided with a top ilange 19, to center itin the well lift. The basket 1S also has many vertical slots 2t?. When in position in the well 1d, it covers the entrance of Vthe feed `tube i6, and holds back particles of foreign matter and chips that may be introduced into the Well 14. The basket may be removed, and with it, foreign matter is 4removed and may be deposited to prevent it from contaminating the fluid in the container 11. The well 14 is positioned in the housing l by the frictional engagement of the ange 15 and the edge 19 with the inside wall of the housing il.

The top `of the container il is closed by a plate or cap 2. This plate Z1 is welded to the top of the container ll. The plate 21 has a central aperture 2?.. An inverted truncated cone 213 is positioned in the aperture 22 and extends down into the Well i4. The cone 213 has a top radial flange 24 which rests on the plate 2l. A pair of eut outs 25 -on the ilange 24 are dimensioned to pass by the heads o-f screws 26, 2.6 on the plate 2d., so that the flange 24 can be rotated to pass under the

screws

26, 26. When the

screws

26, 26 are tightened, the cone Z3 is held in place -in the Well, where its lower end 27 is about at the level with .the top of the basket l. The bottom `27 of the cone has a hinged trap door Z which is kept in a normally horizontal position by the spring Z9; the spring 29 is attached to the outside of the cone 23.

The side wall of the container l1 has a filler port, adadjacent to the tubes 16, 17. A plug 3i) closes the ller port. The plug 3@ has a central enlargement 3l which fits the ller port. A resilient strap or spring 32 is attached to a cross-member 33 on the plug 39. A slotted retainer 34 is attached to the outside of the container il near the bottom thereof. The end 35 of the spring is tted into the slotted retainer 3ft. The top Se of the spring 32 has a hooked or folded portion 37 which embraces and frictionally engages the top of the housing 1i and presses the plug into sealing engagement with the filler port.

The plate 2l is spaced away from the flange 15. The central aperture 22 is delineated by a downwardly extending flange which engages the cone 23 and prevents the material in the container 11 from leaking out if the container l1 is turned to other than an upright position.

It is noted that the air relief tube 17 permits entrapped air to pass so that the container 11 may be filled when laid on its side. The basket 18 will retain foreign matter for easy removal. The trap door 23 helps to contain the contents against spilling if the container is overturned. It is easily pressed aside to admit a dip brush, by the Weight of the brush itself.
