fort, and of such construction that it will be difficult and expensive toreproduce thereby giving a maximum security to' the contents of the containers; and with this and other objects in viewmy invention consists of the parts and combination of parts hereinafter set forth. r

In the drawing: v

Figure 1 is a perspective View of my improved seal before its application to a container. v

Figure 2 is a similar View of the seal as it would appear after its application to a con-' tainer.

Figure 3 is a detail sectional view of a container with mysealapplied.

' The reference number 4 designates a co11--' tainer of any desired shape and size, having, preferably,'but not necessarily, a spout 5, saidspout terminating at its upper end in an inturned annularflange 6 which has an outer substantially horizontal portion andan inner conical or tapered portion,

which latter extendsat an inward and downward angle of inclination, as shown, and is of suflicient rigidity for the purposes of my invention.

My seal consists of a disc 7 which I pre-L fer to have dished, as shown, is provided with a vertical flange 8 atthe top of which is an outwardly extending annular flange 9 of less width than the flange fi and of no greater width than the inner conical or tapered part of said flange 6. This disc or seal 7 is placed in the mouth of the spout with its flange 9 resting on theftop edge thereof, the disc 7 and its flange 8 depending within the spout 5, as shown in Figure 3. Now when the seal is in this position lugs flange 6 of the spout 5.

are upset'by a suitable instrumentv from the flange Sand projectedunderneath and in engagement with the underface of the covered with the usual closure top 11.

As will be seen, the flange 6 is more or less rigid, and likewise, as a result of their formation the lugs 10 are rigid, therefore the flange-6 not only resists outward movement upon an attempt to remove the seal, but the seal cannot be removed or forced from the spout without a destructive effortythat is to say: fn'order to remove the seal it is absolutely necessary either to destroy the lugs 10, the flange 9 ofthe seal or the flange 6 ofthe spout whereby a consumer could readily see that the container has been tampered with and refuse to accept it. 7

The fact that the seal must be made by a special die because ofits construction, and the fact that a special tool is necessary to form the lugs 10 after the disc is in the spout 5 ensures a maximum security against adulteratiom'thereby protecting the manu- 75 facturer as well as the consumer. It, will be observed that as. the flange 9 The spout is then is substantially coextensive inwidth with the downwardly and inwardly inclined inner part of flange 6, said flange 9 seats wholly in the depression formed by said downwardly inclined part offlange 6 and thus is arranged to lie flush with the outer horizontal part of said flange 6. By this arrangement the depressed part of flange 8 6may be held closelybetween the flange 9 and the lugs 10 so that any attempt to re 'lease the seal 7 by either upward or downward movement will result in the flange 6 being bound the more firmly against, the seal and resisting such movements thereof.

Alsoby this construction liability of injury to the seal flange 9 by contact with extraneous objects is prevented and it is not necessary to provide the rim of the receptacle neck with a guard or shield to lie around the flange 9 to protect the same from possible injury. 'Furthermore, the flush arrange ment of the flange 9 provides the end of the container with a smooth and plane surface on which another cap may be stably" rested and which permits of a cap and sealing disk being fitted tightly and in a leakproof inanner-againstthe same; What I claim is: A container providedwith a discharge spout having an inturned rigid marginal flange provided with a horizontal outer por tion and an inner portion extendingcontinuously at a downward and inwardangle of inclination from said outer, horizontal portion, and a sealfor said spout having a closed bottom portion and an annular ver tical flange projecting upwardly therefrom said vertical flange having an outwardly extendlng horizontal flange at "lllS' upper edge lying wholly inthe recess formed by and overhanging the said downwardly and inwardly inclined portion of the marginal flange of the spout and resting upon said inclined portion of the flange so as to dispose its upper surfaceflush with the upper surface of the outer horizontal portion of said marginal flange of the spout, and annularl spaced outstruck lugs on the verticfal' ange of the seal extending under the dlmvrrward1y and inwardly inclined portion ofthe marginalfflange of thespout and holding the latter closely confined between saidlu'gs and said horizontal flange of the seal.
