DI SPENS ING CONTAINER Filed Feb. 1. 1937 INVENTOR BY a r A? A TTO 5Y5 Patented Nov. 1, 1938 PATENT 0F FICE 'DISPEN SING CONTAINER Michael S. Desser,

Toledo, Ohio, assignor to Owens-Illinois Glass Company, a corporation of Ohio Application February 1, 1937, Serial No. 123,370 7 Claims. (01. 215-31) The present invention relates to dispensing containers and more specifically to bottles of the type employing a threaded closure or cap and having a pouring lip ing of the liquid contents of the bottle during pouring thereof.

It is an object of the presentin vention to provide a bottle having a restricted pouring lip which is independent of the threads formed on the bottle neck, which in no way interferes 'with their normal action, which will permit the use of threads of longer efiective length, and which provides a continuous sealing surface around the mouth of the bottle for engagement by the usual threaded closure.

It is another object of the invention to provide a bottle having a restricted pouring lip on the neck portion thereof, which bottle is readily adaptable to the usual forming operations in bottle machines of the Owens type without requiring special operations and without necessitating increasing the over-all diameter of the bottle neck or decreasing the internal diameter thereof or in any other manner restricting the mouth opening in order to accommoutilize standard size caps.

It is another object of the invention to provide a bottle which is capable of efiicient use in the dispensing of cough syrups and other medicines in teaspoon or tablespoon quantities and which, toward this end, is provided with a pouring lip having associated therewith means for guiding the edge of the teaspoon or tablespoon thereagainst in order that the lip shall overlie the edge of the spoon during the pouring of the liquid from the bottle, thus minimizing the effort required (by an invalid for example) to dispense measured quantities of the liquid from the bottle.

Still another object of the invention is to provide a bottle which is also capable of efiicient use in dispensing medicines in drop quantities and which, toward this end, is provided with a pouring lip having a rounded edge which will reduce the tendency of liquids to adhere thereto, thus insuring clean separation of each drop from the succeeding one in the drop-by-drop dispensing of liquids.

Other objects of the invention will become more readily apparent as the description ensues;

In the accompanying drawing:

Fig. 1 is a side elevation of the neck portion designed to minimize spillof a bottle manufactured in'accordance with the principles of the present invention;

Fig. 2 is another side elevation thereof;

Fig. 3 is atop plan viewjof the bottle; and

Fig. 4 is a sectional view taken substantially along the line l 4 of Fig. 3.

A bottle is designated at reduced neck portion H the sides of which are substantially cylindrical. Threads I2 are formed on the neck to accommodate the usual threaded cap or closure (not shown). A shoulder I3 is formed on the neck I I below the threads I2 to limit the downward movement of the cap.

The helix provided by the threads I2 is interrupted at the points l4 and a portion of the glass extending between the ends of the interrupted threads I2 is cut away as at I5 to provide an inwardly and upwardly inclined plane surface I6 which terminates slightly below the level of the mouth of the bottle I0, thus providing a restricted rounded pouring lip I! which overlies the cutaway portion I5. The plane surface I6 of the cutaway portion I5 is in effect formed by the intersection of an inclined plane surface with the cylindrical neck I I as determined by the provision of a suitable insert in the mold in which the bottle I 0 is'formed. The surface I6 extends from an elliptical end point I8 on the cylindrical surface of the neck I I upwardly and inwardly, diverging in width along the elliptical lines of intersection I9 and terminating a short distance below the level of the bottle mouth. The interrupted ends I4 of the threads I2 are rounded and terminate substantially at the elliptical lines of intersection l9, thus barely providing clearance for the cutaway portion I5.

From the above description it will be seen that the thickness of the bottle neck wall is not reduced throughout any material extended area of the bottle neck and the bottle neck is not rendered fragile by virtue of any weakened region thereof. I

Furthermore, by such a construction, the effective length of the threads is increased by a linear distance equal to at least the width of the surface I6 at the elevation of the threads In dispensing liquids in teaspoon or tablespoon quantities, the surface I6 assumes the function of a guide for the edge of the spoon in order that the edge of the spoon may be brought into engagement with the pouring lip I1 with the latter overlying the edge of the spoon. Thus, invalids will not find it difiicult to dispense medicines inasmuch as they will not be obliged to accurately align the edge of the spoon with the III and includes a restricted region that normally exists between the top of the threads and the underneath side of the pouring lip but may slide the spoon edge upwardly through the threads until they locate the pouring lip.

'In dispensing liquids in drop quantities, the

rounded edge of the pouring lip l1 reduces the tendency of liquids to adhere to the lip and thus, clean separation of eachdrop from the succeeding drop in the drop-by-drop measuring of liquids is facilitated.

The extreme upper rim of the bottle mouth'is not disturbed by the undercut portion-l5 below' pouring lip, said lip being contained wholly within the cylindrical confines of said bottle neck, said screw threads being interrupted medially of their ends to accommodate said undercut portion of the bottle neck.

2. In combination, a bottle including a neck defining a filling and discharge opening and having concentric cylindrical inner and outer surfaces, said neck having a continuous annular sealing surface of uniform width at its outer end, external screw threads on said neck, said outer surface of the bottle neck being provided with a cutaway portion having a plane upwardly and inwardly inclined surface below the rim of said neck providing an outwardly extending lateral restricted pouring lip at the mouth of said bottle neck, said pouring" lip being contained wholly 'wit-hintheo cylindrical confines of said neck, the

thickness of the neck wall in the lower regions of said cutaway portion being greater than the thickness-{of t-he wall in the upper regions of, said cutaway portion, the width: of said" cutaway POT-r tion in the lower regions; thereof being less than the width thereof in the upper regions. thereof, said screw threadsbeing interrupted medially of their ends to accommodate said cutaway por tionof the neck.
