4 Claims.

My invention relates to an improved pour pail of the type in which a tamper-proof spout is provided to safeguard the genuineness of the contents thereof until the package reaches the ultimate user.

My invention relates to pails, drums or containers of the type which have a full opening and a cover therefor, adapted to be permanently fastened in place after the container has been filled through said full opening. The cover is provided with a smaller pour opening which is originally closed or sealed against tampering, but which is easily opened by the ultimate consumer for removal of the contents.

The object of the invention is to provide the cover with a weakened or scored portion which requires breaking to form a pour opening through which the contents can be poured.

A further object is to provide a pour lip or spout in association with the pour opening adapted to properly direct the liquid pouring from the opening.

A further object is to provide suitable selfcontained closure means by which the pour opening can be effectively closed to prevent the entrance of dirt from the outside in the event that it is not desired to pour out all of the contents at one time.

A further object is to provide a structure which adds very nominally to the cost of manufacture of the pail or container.

These and other objects of my invention will appear from the following description and claims in conjunction with the accompanying drawings which illustrate several embodiments of the invention.

Referring to the accompanying drawings,

Fig. 1 is an elevational view of the upper portion of a pail including the cover and showing the pour lip and closure lid or cover therefor:

Fig. 2 is an enlarged section substantially on the line 2-2 of Fig. 1;

Fig. 3 is a detail section on line 3-3 of Fig. 2;

Fig. 4 is a top plan view of the pour opening and lip or spout construction of Fig. 1, showing the hinged lid in open position;

Fig. 5 is a section on the line 5-5 of Fig. 4;

Fig. 6 is a top plan view of a modification in which the opening in cover metal is controlled by a rotary valve member, the valve being shown in closed position and sealed;

Fig. 7 is a view similar to Fig. 5, illustrating the valve in open position; and.

Fig. 8 is an enlarged section on the line 88 of Fig. '7.

The upper portion of a typical sheet metal pail or container A is shown comprising a cylindrical structure of sheet metal open to the full extent of its diameter, so that it can be quickly and easily filled. The upper rim of the wall of the pail is turned over to form an annular bead I for strength and for the securing of the cover B thereto after the pail has been filled.

The cover B is made of sheet metal and is generally dish shape in form. Its marginal edge is likewise formed with a bead 2 which is crimped or contracted around the bead I of the pail by suitable machinery to seal the joint after the pail has been filled.

The cover has a flattened inclined portion 3 adjacent one edge to accommodate a pour lip or spout below the top level of the cover, so that the pails may be stacked. Adjacent the edge of the cover, the metal of the fiat portion 3 of the cover is scored or weakened on a curved line 4 so that the sheet metal may be easily broken or separated on this line by any convenient bar or other tool. The score line preferably defines a circle with the exception of the portion between the ends 5 of the line, so that the metal will bend on a. substantially straight line between these ends when the circular portion 6 of the metal is severed on the scored line. Thus while the metal is unbroken on the scored line the pail is closed, but when the scored portion is severed or broken, and then bent inwardly and at an angle, as shown more clearly in Fig. 5, an almost circular pour opening I is provided from which the contents of the pail can be poured.

The scored portion 5 is provided in the bottom flat wall of a circular depressed or dished portion formed in the metal wall of the cover, so that a spout or pour lip member of suflicient depth may be provided without extending above the level of the top of the cover. The annular side wall 8 of this dished portion is substantially at right angles to the plane of the fiat portion 3 of the cover and is larger in diameter than the score line 4 so as to leave a portion 9 of the bottom wall forming a flange surrounding the pour opening.

This construction also provides a suitable means for mounting and fastening the pour lip member in position. The pour lip or spout member C is a trough-like member open at its top and outer end, and generally rounded in cross section to properly direct the flow of liquid from the pour opening. The outer end projects slightly beyond the edge of the cover, and the trough is generally tapered to a. smaller end to liUU properly control the stream therefrom. The upper edges III of the trough portion are straight for the major portion and then incline upwardly slightly, merging in .a round formation at the inner end of the member. The top and outer end of the lip or spout member is adapted to be closed by a hinged cover or lid D which consists of a fiat piece of metal bent to conform to the upper edge of the spout member so that it will fit said edge and form a tight joint when the lid is down. The tightness of this joint is assisted by a marginal flange I i around the lid, the outer portions l2 of which are wider and are formed as ears to resiliently engage the side walls of the spout, the formation being such that when the lid is pressed downwardly the ears l2 will be sprung apart by the upper edges of the spout, and after the ears pass said edges, they spring toward each other and act upon the rounded wall of the spout in a manner tending to draw the lid tightly against the upper edges of the spout. This action also looks the lid in closed position. The outer end of the lid also has a downturned flange l3 which overlies the end of the spout and engages the edge thereof to form a tight joint.

This flange has an indented bead M which snaps under the edge of the spout and holds the flange tightly against the edge. This flange also has an ear extension I5 forming a finger piece which may be conveniently gripped to lift the lid. The lid, as shown, can be swung upwardly and inwardly to a position against the top wall of the cover so .as to be entirely clear of the spout when the contents are poured therefrom. The inner end of the lid has a hinge for this purpose, the hinge being formed by bending an ear portion l6 around a slotted ear I! on the edge of the spout member. The metal of the cover has a bead I8 formed upwardly to bear against the hinge and support the slotted ear I! against being bent accidentally.

The inner end of the spout member has a dishshaped portion conformed to the dished portion of the cover so as to fit therein for the purpose of adapting the spout to the pour opening. The spout member is fastened in place after the two dished parts are nested, by forming several peripherally spaced registering interlocking beads 20 in the side walls of both dished portions as shown in Figs. 2 and 3. The dished portion of the spout member has its bottom wall removed to provide a circular opening 2| slightly larger in diameter than the score line 4 which defines the pour opening.

In the modified embodiment illustrated in Figs. 6 to 8, the hinged lid is not relied upon to close the pour opening, but is simply intended as a cover to keep out foreign matter from the spout. Instead a rotary valve member 22 is provided in association with the pour opening. This valve is in the form of a flat disc having a transverse upstanding rib 23 by which it may be rotated. The disc is positioned between the bottom wall flanges of the dished portions of the cover and spout member, as shown in Fig. 8, the space 24 between these flanges being made suflicient to allow the disc to be rotated easily in its own plane. In this case, the pour opening 1 is made smaller and is defined by the semicircular score line 4. The disc valve also is provided with a similar shaped opening 25 which is adapted to be brought into and out of registration with the pour opening by the rotation of the disc, to open and close the pour opening.

In this modified structure means are provided to seal the disc valve in closed position if desired. The bottom wall of the dished portion of the spout has an ear or lug 26 formed up and provided with a hole 21 adapted to register with a hole 28 in the rib 23 of the disc when the disc is in closed position. A sealing device in the form of a wire 29 is looped through these holes and fastened by the usual sealing lead.

In this case the pour opening in the pail cover can be formed originally, and the closed and sealed valve can be relied upon to render the structure tamper-proof.
