PAPER BOTTLE.

Specification of Letters Patent.

Application filed January 25, 1915. Serial No. 4,099.

To all whom it may concern:

Be it known that I, HARRY C. AYERsT, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Paper Bottles, of which the following is a specification.

This invention'relates to bottles which are molded from pulp formed of paper stock or an equivalent, by means of a suitable machine like, for example, that illustrated and described in patent application, Serial No. 869,243, filed by me October 29, 1914.

The object of the present invention is the production of a bottle formed of a pulpy material and which is designed, more especially, for use as milk containers.

The invention consists of a novel construction of bottle, as will be hereinafter described and claimed In the accompanying drawings, Figure 1 is a transverse vertical section of" a bottle embodying my invention. Fig. 2 is a fragmentary front elevational view of the bottle shown in Fig. 1. Fig. 3 is a longitudinal view of the preferred form of a bottle-tap whereby the cream may be drawn from a bottle containing milk.

According to this invention, a bottle is formed of pressed or molded wood' pulp or other suitable macerated material.

As illustrated in Fig. 1, A represents the body of the bottle having a neck B and an annular rabbet C in itsmouth to accommodate a cap such;"for instance, asusuallyemployed for milk-bottle closures. The bottle Wall is furthermore made at predetermined distances from its top with relatively thin portions which are adapted to be removed by the insertion of a tap for the purpose of withdrawing the cream from the bottles contents. Such weakened wallportions are formed by the provision of recesses D and D inthe outer periphery of the wall and are desirably each formed with a flaring periphery E which terminates in an annular groove F.

The referred to tap, see Fig. 3, comprises a tube G which tapers, as at H, toward the front end of the tap. The latter is made or sharpened to present circular cutting edge .I and one or more serrations, as K, are cut into the tube to provide supplemental cutting edges L.

The tap is used by pushing the same into a selected one of the recesses D while imparting a rotary motion to the tap so that the wall material is cut away at the bottom of the groove F to allow the tap to beinserted in the bottle, as indicated by broken lines Gr in Fig. 1.

By reason of the taper on the tap, the latter, when shovedinto the bottle, tends to cause the surrounding portion of the bottle to embrace the tap and obviate any leakage thereat. a

The recesses D and D are positioned at different elevations, so that either may be selected according to the desired quantity and quality of the cream.

The invention is of simple and inexpensive construction, and is designed to be destroyed after it has been once used.

What I claim-as my invention, is

As a new article of manufacture, a milk bottle made of molded pulp having adjacent its upper end an integral weakened draw-off tap receiving portion whereby substantially purer cream may be withdrawn from the bottle, and having between the aforesaid weakened portion and the bottom of the bottle a second .weakened tap receiving portion whereby a mixture of cream and milk may be withdrawn.
