PAPER VESSEL.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed March 7. 1906. Serial No. 304.632.

T 0 all whom it may concern:

Be it known that I, BERroN I. BIKE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Paper Vessels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in paper vessels.

The object of the invention is to provide a paper vessel so constructed that the mouth thereof will remain closed in a most effectual manner without the employment 9f eyelets or other retaining means. The closure flaps consist of folds of substantially uniform dilnensions which overlap each other in closing the mouth of the vessel, and join end extensions the natural resiliency of which exert a pressure on said closure flaps to maintain them snugly in their overlapped positions, and also the end extensions are likewise overlapped in a substantial manner so that leakage through the mouth of the vessel at any point is prevented.

In the accompanying drawings,-Figure I, is a plan view of the blank from which the vessel is formed. Fig. II, is a perspective view of the upper end of the mouth of the vessel showing the same closed by the overlapping closure flaps which join the end extensions which are likewise overlapped in a substantial manner. Fig. III, is an elevation of the inner side of the vessel showing the triangular folds on the inner side and the closure flaps and end extensions open.

In a detail description of the invention, similar reference characters indicate corresponding parts.

The vessel is constructed of a suitable quality of manila paper out and scored in a mannerto form the vessel as shown in the view of the blank given. in the drawings.

When folded, 1 designates the bottom; 2 2 the outer opposite side walls, and 3 3 the outer opposite end walls. The side walls 2 2 and the end walls 3 3 are brought together by inwardly-breaking bellows folds 4 and 5 which break u on intervening score,

8 3 on the outside lines to bring the wal s of the vessel.

The score lines between the V 4. and 5 break inwardly, and when the blank is folded to form the vessel, these triangular folds 4 and 5 lie on the inside of and against the side walls 3 3.

Extending from the triangular folds 5 5 are extension folds 6 6 which form continuations of said triangular folds 5 5 to the top or mouth of the vessel, so that when the folds 4 and 5 are placed against the inner sides of the walls 3 3, there is a continuous unbroken surface or wall extending from the bottom of the vessel to the top of the end extensions 6 6 and thereby the contents of the vessel are prevented from leaking through the top of the folds 5 5. I

7 7 designate the closure flaps which extend across the mouth of the vessel and are folded over the mouth of the vessel one upon the other, and are reinforced to strengthen them. These closure flaps 7 7 overlap a substantial distance in closing the mouth of the vessel and are maintained closely together when so overlapped without the usual additional fastening means. The said closure flaps 7 7 have end extension folds 8 8 extending from each end and which join the extension folds 6 6 by an intervening score line, and the extension folds 8 8 are likewise overlapped to a substantial extent to form a complete closure at the top of the vessel on each side or end of the overlapping closure flaps 7 7. When the closure flaps 7 7 are folded inwardly, as in Fig. II, the folds 6 and 8 bend upon score lines 6 6 and lie against each other snugly, and the folds 8 8 and 6 6forn1 upright extensions which join as before stated theends of the closure flaps 7 7. These upright extensions so formed by overlapping triangular folds 6 and 8 reach above the end walls 3 3, and are not bent over the mouth of the vessel as is customary, but stand upright when the vessel is in a serviceable condition and exert a certain amount of inward pressure upon the overlapping folds or flaps 7 7 to maintain them in snug contact. It will be seen from Fig. II, that the bail or handle 10, when placed in an upright position, presses against the outer sides of said upright or end extensions and exerts a certain amount of inward pressure upon said upright extensions which is instrumental in causing the pressure on the overlapping closure flaps 7 7 before stated. This inward tension upon said upright or end extensions is increasedwhen the vessel is made to contain a weight, such as the triangular folds commodity placed therein, and while the vessel is being carried in the hand. The folds between the cover flaps 7 7 and the extension folds 8 8 are upon the score lines 8 8' and said score lines impart a constant outward ress'ure which maintains the overlap ing .olds 8 8 in close contact with the outer f dlds 6 6, and'renders unnecessary any means other than this pressure for maintaining said folds in close contact. The same outward pressure along the score lines 8 8 also serves to hold one closure fla for example, the outer closure flap 7, in c ose contact with the inner closure flap 7. The natural resiliency of the material manifests itself readily in the initial operation of closing or overlapping the flaps 7 7.

The side walls 3 3 may be united to the inner rectangular folds 4 and 5 in any suitable manner, but the most desirable means consists of a suitable number of wire fasteners 9 which penetrate said parts through openings 10 and are clenched on the inner sides of the triangular folds at the top of the vessel. The wire bail or handle 10 before referred to, is employed and is united to the top of the side walls 3 3 through central openings 10; the ends of said bail 10 also pass through similar openings 1 in the triangular folds 4 and 5.

From an inspection of the blank as illustrated in Fig. 1, it will be seen that the closureflaps 6 7 and 8 are of the same area and shape respectively, at both ends of the blank this form an overlapping cover for the mouth of the vessel, and the end walls of said vessel consisting of two two-ply overlapping folds which fold against a single thickness of the blank and terminate in top extensions which stand upright and join on their inner sides the overlapping cover extensions, the folds of said top extensions overlapping on their inner sides throughout the lengths of said top extensions and thus forming a complete overlapping closure for the mouth of the vessel from the upper extremity of one of said top extensions to the upper extremity of the other of said top extensions.

In testimony whereof Iafiix my signature, in presence of two witnesses.
