j frolaims'. (01. 215-11 I My invention relates bottlesj and particularly to bottles from the-necks oflwhich liquid-is bottles; and it also relates to bottles from which liquid is to be poured in a steady stream, un.- currents entering-at the bottle broken by air mouth; 1 l This invention is a modification ofv the invention for which I filed an application forpatent on October 22,1942, Serial 'No. 463,009; now

Patent No. 2,342,722, February 29, 1944; in which application I described a bottle having on its body and near its base a projecting hollow boss form ing an air inlet to the bottle, the said boss having on its side a slot affordingapassage for air into the bottle.

In the present application I describe a bottleof the boss and into'the bottle. The opening in the side of the boss may be in the form of a round hole; of somewhat larger size than the perforation through the side wall of the closureyor it may be in the form of a slot through theside wall'of the boss; or it may be in the form-of a flute within the limits of which a hole is formed into the inside of the boss. whenthe hole through the side wall of the boss is elongated, as in theform of slot or'flute, it is easier to register with it the small perforationin the side wall of the closure. i'

In the drawing: I y

Figure 3 is a partial longitudinal section of the bottle, showing the glass boss on the side of the bottle, and with air retaining closure in vertical section.

Figure 4 is a partial longitudinal section asin Figure 3, but showing a flute cast inthe side of the boss and a perforation through the boss and within the flute.

Figure 5 is a cross section through the boss on line c--d in Fig. 4.

Figure 6 is a partial side View of the bottle It will be seen that drawn by the mouth 1 and IiDSpSllCh as .'nu-rsing showing the boss capped y an air retaining closure. v, v 1 v v Figure 7 is .a cross section through 'the'boss and closure on line e'f in Figure 6.

A' special feature. of. my present'inventionis that the elastic closure fits snugly aroundthe boss on the side of the bottle, yet not so tightly that it maynot be twisted or turned on the boss;

and further: that the closure is punctured by a smal1hole ora slit in its side; which puncture 'niay, when the closure is turned on thevboss, be

made to register with an opening through the side of the boss; and so communicate with the inside of the boss and of the bottle. 1

- In Figure 1: The numeral 2 indicates the glass of; the nursingbottle, which is shown laid upon its side. On the opposite side of the bottle there is formed an annular boss 4, through which passes a large vent-hole 6 into the inside of the bottle.

2; see Figures 2 to 7 inclusive. Thetbottle is shown in the position commonly .used when feeding an infantyand it is obvious that if no air were allowed to enter the end of the bottle-a partial vacuum would be formed in the bottle'as liquidis drawn from the mouth of the bottle;

and when the bottle is being used for nursing, with nipple, .not shown, the vacuum within the bottle will cause thenippleto collapse and to I impede the flow of liquid from the mouth of the bottle. 1

The object of this invention-is toprovide a nursing bottle in which this partial vacuum-may be reduced without introducing any unsanitarymeans; which bottle may be with certainty cleaned and sterilized; which shall be inexpensive and durable; and which may be operated and held by one hand of the nurse in attendance.

To prevent leakage: bossidis closed by an This closure may be other material which is waterproof, and which shall be suficiently elastic to fit the boss snugly,

elastic ca or closure II].

to cover the bossso that no liquid may leak from the inside of the bottle when the bottle is stood on end.

In the side of the closure I0 there is made a puncture [2. This puncture may be in the form of a small hole, as in Figures 2, 3, 4, and 5; or in the form of a small slit, as in Figures 6 and 7.

In Figure 6 this slit is shown as if having an inside of the boss than on the outside so that v The bore 6 through the made of rubber or of anyliquid lodging against the cap Ill may drain back into the bottle. Air is admitted to the inside of the boss and bottle by turning the cap ill on the boss 4 until the small puncture l2 registers with the hole [4. Air will then pass into the interior of boss and bottle through the puncture l2 and the hole M.

In Figure 4 the outside of the boss is shown fluted at I 6. It is also shown as perforated at 18 within the boundaries of the flute (6. When this perforation I8 is not used with the flute, the air channel to the interior of the boss may be made by means of a depression 20 in the boss wall at the upper end of the flute. The object of the flute i6 is to give a greater range to the registering of the puncture in the cap with the hole It; for obviously, though the puncture in the cap 12 may not register directly over the hole I8, it will register with the flute, by which the air will travel to the hole I8. A cross section through the flute l6 and hole I8 is shown in Figure 5.

As stated above: The puncture l2 in the capclosure in may be in the form of a small hole, or of a small slit. In Figure 6 I have shown, in

k elevation, a cap-closure snugly covering a boss;

in which cap-closure there has been made a small slit l2. Beneath the slit is shown, in the wall of the boss a flute or even a slot 24. In the cross section in Figure 7 this opening in the wall of the boss is shown as a slot, which is cut or cast through the side wall of the boss. When the slit in the cap-closure is made with contact ing side walls there will be little or no leakage through theslit when'th'e bottle is placed on end; and when in the position shown in Figures 6 and 7 it may be necessary to press upon the capclosure at a point adjacent the slit to open the said slit to admit air to the inside of boss and bottle.

Iclaim:
