BOTTLE.

Original application filed April 22, 1927, Serial No. 185,848. Divided and this application filed January are seated for sealing the bottles. These cir- 1 cular closures are usually made from pulp or card board, and 111. stamping out the discs there IS an unavoidable waste or loss of the fibrous stock amounting to about twenty-five per cent, which greatly increases the production cost.

The present invention has for its primary object to eliminate all waste in the manufacturing of the bottle closures, and to this end, the bottle is provided with a substantially square depressed mouth defined by an upwardly facing bead or rib of square configuration, the bottom of the depression being molded to receive a substantially square cap or closure. Such a closure is shown in the present case, and as will be understood may be stamped or cut from a plain sheet or strip of the fibrous material, without any waste or loss, and when suitably prepared, the closure is formed with a depressed portion which conforms to and snugly fits the recess of the mouth and effects a perfect seal. Furthermore, squaring the mouth greatly facilitates extracting the contents of the bottle, which may be poured in a controlled stream from one of the angular corners of the mouth, likev liquid may be poured over the protruding lip of an ordinary pitcher. The head at the-four sides of the recess is preferably flared to enable correspondingly rolled or flared portions of the closures to overlie the head for shielding the pouring surfaces of the mouth from germs and dirt.

The various features and parts of the invention will be understood from the detailed description which follows, and by reference to the accompanying drawing, in which Fig. 1 is a top plan view of a bottle, showing a square depressed mouth. Fig. 2 is a broken side elevation and partial central Serial N'o. 246,552.

vertical section of the same, the latter taken on line 2-2 of Fig. 1. Fig. 3 is a similar section showing a square closure fitted. to the correspondingly shaped mouth. Fig. 4 is a plan view of a plain strip of fibrous material from which the square blank of the closure is cut. Fig. 5 is a plan view of one of the closures showing the blank creased for providing a square central. portion; also showing the corners creasedfor iii'acilitating shaping the angular apron. And Fig. 6 is a transverse section, taken on line 6-6 of Fig. 5; showing the apron at the opposite sides of the blank slightly convex.

In the drawing, 2 represents the body of a cylindrical bottle having a reduced hollow neck 3, which is surrounded the usual annular bead 3. Above the head 3 the neck is formed with a square upward. y projecting head or rib 1, whose outer walls 1 are preferably parallel to the axis of the bottle, the inner walls 4 of the bead preferably being flared, as best seen in Figs. 1,2 and 3. The mouth ofthe bottle comprises a square depression or recess 5 that lies within thebead 4, the bottom 5 of said recess being in a plane at right angles to the axis of the bot tle and parallel to the free edge of the head 1. The neck 3 is preferably round, and the ledge 5 is formed with a concentric ircular opening 3, for the filling as well as for drawin off the contents of the bottle. The ledge 5 is preferably square and is slightly broader than the opening 3 for providing a continuous and ample seat around the said opening upon which a depressed portion of the closure, as 6, rests (see Fig. v

a The closure 6 comprises a substantially square sheet of fibrous material, such for example, as pulp-board, which is preferably flexible and also slightly compressible, and may be cut or stamped from a plain sheet of the material. The blanks 6 are usually fed into a suitable machine (not shown) that first forms a V-shaped crease, as 6, of square configuration, by means of suitable dies, which also crease the four corners of the blank obliquely beyond the crease G, as shown at G in Fig. 5. The/corner creases are also V-shaped and preferably taper towards the corners of the blank, their inner ends intersecting the crease 6, for enabling the blank to be folded and molded to conform to the flare, angularity and depression of the recess 5 (see Fig. The creasing operation is usually followed by a slight rolling or convening of the four marginal portions, as 6 (see Fig. 6). The crease 6 enables the central portion, as 6 to be de pressed, to the extent shown in Fig. 3. By forming the several creases V-shaped facilitates the inward folding of the four margins G of the blank that lie beyond the portion (3, for providing the continuous apron (3" that overlies the flared inner walls 41-. of the rib l. After the blanks are creased and molded, as shown in Fig. (3, they are left in the latter state until delivered to the bottleiz. The prepared blanks are relatively thin and flat and enable a bottler to stack a large number of the closures in the usual. magazine (not shownlfrom which they may be fed towards the capping position. The several creases (36', render the blanks sullicienljly pliable to enable the capping plunger (not shown), to properly apply the closure to the recess 5, as shown in Fig. The plunger must nee rily be substantially square, and by squaring the outer walls 1-. of the rib l, en ables a belt or other means that usually conveys the filled bottles towardsthe capping position, to accurately spot, or so dispose the bottles that their square mouths always coincide with the plunger. The magazine should be square in cross-section, and also so positioned that when the closures are ejected, the latter may be brought into registry with the square mouths of the bottles.

The provision of the relatively broad square seat 5 and the relatively sharp angles at the intersection of the said seat with the rib 4-, facilitates the positive sealing of the bottle month, by means of a' closure of novel and extremely simple and economical construction.

From the foregoing, it will be seen that the circular bore of the neck is surrminded by a. multiplicity of pouring portions each of the latter having angularly related sides; The here is common to all. of such portions and due to the depressed part which provides such pouring portions being spaced from the bore, a continuous ledge 5 a'l'i'ording a seat for the closure is provided.

Having thus described my invention, what I claim is 1. A bottle having a cylindrical neck formed with a square depressedmouth,and an annular bead surrounding said neck, said mouth lying within a continuous angular rib that rises above said head, the bottom of the mouth comprising an angular ledge arranged parallel to the free end of therib, the inner faces of said rib being convex, and the outer faces of the rib being in planes parallel to the longitudinal axis of the neck.

2. A bottle including a cylindrical neck,

the free end of the neck being formed with a recessed mouth defined by a rib of substantially square configuration, the outer walls of said rib being parallel to the longitudinal axis of the neck, and the bottom of the mouth comprising a ledge disposed at right angles to the said axis and extending beyond the opening in the neck adapted to support a. square closure for sealing the mouth.

3. A bottle having a cylindrical hollow neck formed with a circular bore and with a substantially square depressed month, said mouth being defined by a continuous lip of square configuration spaced from the bore, the bottom of the mouth comprising a ledge substantially square in plan and arranged in a plane at right angles to the axis of the neck adapted to seat the correspondingly shaped portion of a closure, and the inner faces of said lip being flared and adapted to seat an angular rolled apron of the closure.

4:. A bottle having a hollow cylindrical neck having a. circular bore and formed near its free end with. a circumferential bead, said neck being formed beyond the bead with an upstanding rib of square configuration for defining the recess of the mouth of the bottle, the outer walls of said rib being parallel to the longitudinal axis of the neck, the inner walls of the rib being spaced from the bore and flared inwardly and downwardly and terminating at a ledge that forms the square bottom of the recess, said ledge constituting the seat for a closure having a concave square portion and an angular external rolled portion that overlies said liar-ed walls.

5. A bottle having a cylindrical neck formed with a substantially circular bore, and ahead on the upper end of the neck fin-med with a depressed part having angularly related sides which surrounds said circular bore so as to provide a multiplicity of pouring portions for the bore, the said depressed part being spaced from the circular here to provide a continuous seat for bottle closure.

G. A bottle having a cylindrical neck with a substantially circular bore, and a bead on the upper end of the neck formed 'ith a depressed part having angularly related. sides which surrounds said circular bore so as to provide a multiplicity of pouring portions for the bore, thesaid depressed part being spaced from the circular bore to pro vide a continuous seat for a bottle closure, the outer faces of the bead being llait and disposed in planes parallel to the longitudinal axis of the bottle. i

In testimony whereof I allix my signature.
