BOTTLE CLOSUJRE OR CAP.

Application filed August 15, 1921. Serial No. 492,356.

To all whom it may concern:

Be it known that 1, ROBERT MURCHIE, a citizen of the United States, residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Bottle Closures 0r Caps, of which the following is a'specification.

My invention relates to bottle closures 01' caps, and pertains particularly to caps co nstructed of paper or other similar material as used principally on milk bottles.

An object is .to provide a removable cap for a bottle so constructed that the cap may be opened to discharge the. bottle contentswithout entirely removing the cap from the bottle, but likewise permitting easy removal of. the entire cap if desired.

A further object is to provide a simple, inexpensive form of bottle cap, comprising a lower perforate layer adapted to be removably fitted within the mouth of a bottle and an upper imperforate layer hinged thereto adapted to likewise fold within the bottle mouth but so constructed that it may be upraised uncovering the aperture through the lower layer of the bottle cap.

A further ob 'ect is to provide a-bottle cap of form described above provided witha hinged folding section adapted to unfold forming a discharge spout for the contents of the bottle as they pass through the perforation in the lower layer of'the cap.

.These and other objects together with details of construction will more fully appear from the following description, appended claims and accompanying drawlng, in

which: i Fig. 1 is a perspective view -showing'the upper portion-of a bottle with my improved cap in place therein.

Fig. 2 is a plan of the upper surface of the 1 ,cap.

.Fig. 3 is a plan of the upper surface of the cap, the closure layer being upraised.

Fig. 4 iskan elevation of the. intermediate folding section of the cap. Fig. 5- is a plan of the lower surface of the cap,. I C

In the drawings, let 1 indicate abottle, the upperportion ofwhich is-shown in Fig. 1, withinthe mouth of-which' the cap is fitted. ,A suitable material for'the construction of-the cap is paper, as used extensively for milk bottle caps today. -The cap comprisesa lower,- apertured layer 6. Layer b is pro-v vided with a large central perforation c slightly elongated so the fluid will flow easily therethru over the provided spout. The lower apertured layer is adapted to fit snu ly within the mouth of the bottle.

Iiinged at one side, to the upper surface of the apertured layer is an imperforate layer F. This imperforate' layer maybe glued, riveted, or otherwise secured to the apertured layer, scored along the line 6 as shown in Figs. v1, 2 and 3, so as to be upraised uncovering the perforation c. This imperforate layer is adapted to fold down over the perforated layer within the mouth of the bottle, fitting closely within: the bottle mouth so as to be retained in position therein.

There is provided an intermediate folding section D. The middle section 9 which is se-' cured to the imperforate layer, and the free ends h, k and h are secured to the perforated layer near the margin of the aperture therethru. This may preferably be accomplished by turning these ends within the perforated layer. The side portions 2' and z' of this intermediate section are scored along the dotted lines in Fig. 4, so as to unfold as shown in Figs. 1 and 3, or to fold down' between the upper and lower layers of the cap, when the upper layer is closed down within the mouth of the bottle.

This folding section forms a trough-leading from the perforation over the imperfoe rate layer and serves as a spout through which the liquid contents of the bottle may be discharged. The folding section is continued to form a tab it by means of which the imperforat layer may be raised so as to uncover the amerture through the lower layer f the cap.

Having thus described my invention, what I claim is:

1. In combination with a bottle, a cap adapt d to be received within the mouth thereof comprising an apertured layer adapted to fit'snugly in said mouth, animper orate layer hinged to said apertured layer and adapted to fold thereover, within said mouth, a folding wall section positioned intermediate said layers so as to fold'therein against when the imper-forate layer is closed down over the apertured la er and adapted 5 the bottle, an imperforate complementary layer hinged to the 'apertured layer on one side adapted to fold thereagainst within the mouth of the bottle, an intermediate folding section secured to said imperforate 110 layer and to said aperture layer near the margin of the perforation therethru in such a manner as to fold therebetween when the iinperforate layer is closed down against said perforated layer and to unfold so as to form restraining walls of a trough leading from said aperture over the adjacent surface of said imperforate layer when said iinperforate layer is upraised.
