For this purpose the binder sheet 26 preferably is made of a relatively thin, tough and strong, tightly pressed fibre material. This binder sheet extends over the entire outer surface of the end member 25 and is permanently secured thereto by a film of a suitable waterproof adhesive 29 (Fig. 3).

The binder sheet 26 is of larger dimensions than the end member 25, having marginally extending edge portions 30 which are wide enough to extend downwardlyagainst and are adhesively secured to the outer peripheral edges 28 of the end member 25 and the adjacent outer peripheral edges of the flange 2|, and wide enough to project under and being adhesively secured to the lower outer surface of the flange 2| as best shown in Fig. 3. In this manner the binder sheet locks and retains the end member in place and protects it against damage as mentioned above, and at the same time provides for the container a smooth flat top, free from any crevices or indentations so that surface liquids or other foreign matter will be prevented from collecting on the top of the container.

The duplex closure member [2 preferably is provided with a dispensing opening 32 (Figs. 2 and 3) formed in the duplex closure member if adjacent one of its corners. The binder sheet 28 also has an opening in alignment with the dispensing opening. This dispensing opening 32 preferably is surrounded by a protecting and reinforcingbarrier comprising a flat barrier member 33 of relatively thick fibrous material perinanentlysecured by suitable waterproof adhesive 34 (Fig. 3) to the outside surface of the binder sheet 26. The barrier member is formed with an opening 35 (Fig. 1) which registers with the dispensing opening 32. The outer edges of the barrier member 33 adjacent the outer edges of the duplex closure member l2 preferably coincide with the edges of the closure member. Inwardly of the edges of the closure member, the edges of the barrier member form a stepped barrier which deflects surface water or other foreign matter, away from the dispensing openings 32, 35.

A friction plug closure element 31 is provided for closing and reclosing the dispensing openings 32, 35. This closure element 3'! extends over the top surface of the barrier member 33 to maintain it free from contamination and is hingedly secured thereto by a wire staple 38 disposed adjai cent the inner barrier edge of the member 33.

In some cases it may be desirable to protect the entire top of the container including the friction plug closure element 31. For this purpose an overcap 40 (Figs. 4, 5, and 6) may be applied over the duplex closure member [2. In the form of overcap disclosed in the drawings, the triangular portion opposite the friction plug closure element 3! is permanently secured by a suitable waterproof adhesive, to the outer surface of the binder sheet 26, the outer peripheral edges of the overcap terminating adjacent the outer peripheral edges of the duplex closure member [2 as best shown in Fig. 5.

The triangular portion of the overcap 43, that overlaps the friction plug closure element 31' is formed with a hinge crease 39 which connects this portion to the opposite secured triangular portion of the overcap and is free from the binder sheet 26. This free triangular portion of the overcap is provided with an overhanging marginal edge portion 4! which extends down over and around the combined outer peripheral edges of the plug closure element 31, the barrier member 33, and the duplex closure member l2, and is crimped in place under the flange 2|, as best shown in Fig. 5 When the free portion of the overcap is in protecting position as shown in Fig. 4. When it is desired to open the container, the free portion of the overcap 40 may be readily lifted and access obtained to the plug closure 31 as shown in Fig. 6.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
