A 'Ihis invention relates to improvements in receptacle closures and has particular reference to a cap to be used upon bottles andthe like. l

An important object of the invention is the provision of a cap for milk bottles and similar receptacles formedso as to be conveniently bent outwardly in segmental form so that only aportion of the bottle may be vAnother Object of theV invention is to provide a cap of the above character which vmay -be lpartially opened in desirable segyA still furtherobject of the invention is Y the provisionfof a cap formed so as to be conveniently crushed inward for removal or partial opening of the container.

Stillanother object of the invention is the provision of-a cap adapted to enclose a milkbottle or similar receptacle and designed so as to be partially folded so'as to open' a comparatively small portion of the receptacle when desirable. v

Other objectsandadvantages of the invention Will `become apparent as the descrip-V 40 partially .in open position shown mounted in association with a container, and

Thus the contentsof the bottle are exposed to dust and germsto quite a large extent. ticularly to a cap designed to permit'partial My inventionrelates paropening so that only enough of the cap isV raised to per-mit delivery of the contents. IV ith this in'mind, the bottom ofy `my improved cap 10 is provided with a series of transversely extending grooves 11 prefer-vk ably impressed about half Waythrough the cap so that a portion of the cap may be readily turned upward.

lVith particular reference to Figure 2, it Willbe seen that my cap is'preferably pro. vided with av pair of central intersecting Grooves 1l and 12 and a air of Grooves eX# tending parallel Withone of the central transverse-grooves in spaced relation so astor divide the cap Vinto V.segments ylessthan one? half thereof. Each vof these segments designed by the numeral 13 isv capable of loeing raised so as to only partially uncover the milk bottle or other container but `sufdelivery of the milk therein.

It is evident, from the foregoing, that the cap after being securely mounted inthe milk bottle may be raised by elevation of one of the end Segments equal topractically onees'v fourth of they area ofthe delivery openingV or, `if desirable uncovering three-quarters,

It is thus apparent that a bottle oap` of simple yet efticient'design provided, tendmg to retain milk and similar matter in re vceptacles in moresanitary condition.
