GUSTAV A. AICHER, OF SAN FRANCISCO, CALIFORNIA.

MILK-BOTTLE CLOSURE.

Application filed February 11, 1926. Serial No. 87,518.

This invention relates 'to a closure for milk bottles provided with a hole which is covered with a thin sheet of parafiined paper to'allow the opening to be easily made when the milk is to be removed from the bottle.

It will be understood by those skilled in the art that the ordinary fiat card or box board milk bottle cap is not easily removed from the top of a milk bottle unless provided with a special. removing device of some kind, and when it is desired to drink the milk from the bottle with a straw it is necessary to have only a small hole in the cap through which the straw can be inserted any way.

In the present case the hole is made about one half inch in diameter, closures are then while in the sheet printed and covered with a paraflined sheet which seals the holes, and then the closures are finally cut out clear with a die. In this case, if the paratlined hole cover is punched out the contents may be poured out through that hole,.;or the finger may be inserted in the hole and the closure lifted out, in either event there is no danger of causing the milk in a full bot- ,tle to be squirted all over the user, as often happens with the plain caps. 7

Another object of the invention is to provide a closure which can be easily printed, and which will show the printin notwithstanding the fact that the printing ink is so covered that the cream can not touch the same, and thereby would prevent contami-.

nation of the mil An embodiment of the invention is shown in the accompanying drawings in which the saniereference numeral is applied to the same portion throughout the several figures of the drawings, and of which there may be modifications Figure 1 is' a perspective view of the plain closure with the'paraflined paper cover over the hole. v Elgure 2 is 'a section of the closure as it appears on the bottle.

Figure 3 is a perspective view of a closure with a-lifter at its edge, the lifter being cut out of thewaste material between'the severalclosures.

Figure 4 is a section of the closure as it appears on the bottle.

Figure 5 is a view of a sheet of paper or part of the sheets of pulp board as it --appea rs when printed.

Figure 6 is a plan view of one of the disks showing the printing appearing therethrough. I i i The numeral 1 repre3ents a circular bottle closure cut from a sheet of pulpboard, a hole 2 being first cut in the sheet to correspond with the position of each closure to be cut therefrom. When the hole has been cut the entire sheet is covered with another sheet 3' after which the entire sheet is cut out to produce a large number of the closures 1. As the center hole is then covered with a thin sheet of paper it is easily punched out either to drink the liquid with a straw, to enable the liquid to be easily poured out, or to enable the closure to be easily taken out of the bottle.

In the sheets forming a series of the closures, there is a certain waste between the closures which may as well be used to pull out the closure if desired. In this form of the invention the hole may be placed eccentrically to allow the milk to be poured out more easily.

The pulp board closure is s own at 6, it

has the paraffined paper 7 secured thereto,

vantage t'or the reason that the cream of the milk is always more or less contaminated by the ink on the legend printed ,on the cap,'so that in the present instance'the printing is ordinarily done on the sheet of transparent paper and this sheet is thereafter secured to the closure with'the printing on the inside thereby completely protecting the milk against contamination from the ink.

In this case the sheet 9 which may be.

either the transparent sheet or the pulp board, is rovidedwith the necessary printing, andt is printing is placed between the two layers 6 and 7 so t at it w ill appear through the transparent sheet. If the printing is on the pulp board it willjbe printed as shown in Figure 5. If the printing is on the sheet 7 it will bereversed so as to be readable through said sheet. In either instance the sheets are secured together with some adhesive. or hot parafline after the 4 printing is effected. Having thus described my invention, what I desire to secure by Letters Patent of the United States is as follows, but modifications may be made in carrying out the invention as shown in the drawings and in the above particularly described form thereof, within the purview of the annexed claims.

1. A milk bottle closurecomprising a pulpboard disk having a transparent covering with printing visible through the transparent covering.

2. A milk bottle closure comprising a pulpboard disk, a substantially transparent covering for said disk with printing visible therefor, printing 'in'lreverse on said transparent cover, said transparent cover being adapted to be pasted on to said disk with the printing next to said disk, and readable through said transparent cover.

4. A milk bottle closure comprising a pulp board disk, printing on said disk, and a transparent paper cover for said printing.

In testimony whereof I have hereunto set my hand.

GUSTAV A. AICHER.
