Description

Dec. 16, 1958 E. PlTAVY FEEDING-BOTTLES OBTURATED BY A SCREW PLUG Filed March 11, 1955 United States Patent FEEDING-BOTTLES OBTURATED BYiA SCREW-PLUG Edmond Pitavy, Paris, France Application March 11, 1955, Serial N 0. 493,650

Claims priority, application France January 21, 1955 3 Claims. (Cl. 215--11) The present invention relates to improvements in feeding-bottles and particularly those employing a nipple for use in feeding infants.

There are at present several kinds of screw cap type feeding-bottles in use, and among them are:

(a) Those having a screw cap with a single thread and including a disc for closing the mouth of the bottle during the carrying thereof.

With these types of feeding-bottles the nipples have to be manually turned in its cap at the time of use and therefore are not sterile.

The obturating disc placed, during the carrying of the bottle, in contact with the inside of the nipple must also be sterilized and may possibly be lost during use of the bottle;

(b) Those having a socket with double threads and a center collar, with closing disc.

With these kind of feeding-bottles the nipple is placed in its socket and the unit is sterilized.

The subsequent handling thereof is done from the outside of the socket which is screwed on the neck of the feeding-bottle so as to place the nipple in the neck of the bottle for its carrying position or outside and in the extension of said neck in its position for being used.

With this device a sterile state is obtained, but the projecting part of the socket, having one of the threadings, hampers the babys drawing on the nipple.

Also, the closing disc has the same drawbacks as the previously described feeding-bottle.

The present invention removes these aforementioned drawbacks and is characterized in that:

(a) A screw cap having only one thread for attachment to a similar thread on the neck of the bottle is used;

(b) There is no closing disc used here;

(c) The nipple and the screw cap are protected during the carrying of the bottle, by an outer cup shaped cap screwed onto a second thread on the bottle and of a larger diameter than that of the first mentioned threads on the neck of the feeding-bottle.

With this device the nipple is placed in its screw-cap, in its position for being used and both parts are sterilized. Then the nipple is introduced into the neck of the feedingbottle with the outer holding the cap by its outside periphery.

In this position the screw cap is mounted on the neck of the feeding-bottle in an upside-down position.

The unit is covered by the cup shaped cap of which the bottom, shaped accordingly, presses on the flange of the nipple and therefore the tightness of the sealing thereof.

In two possible modifications of the present device:

(1) If the nipple includes a single flange and a suitable shoulder holding it on the screw-cap the main part of said nipple as well as its shoulder are slightly forced into the neck of the feeding-bottle so as to eflect its tightness or sealing and furthermore the bottom of the outer cap 2,864,520 Patented Dec. 16, 1958 is in the shape of a truncated cone so as to press from the inside towards the outside on the flange of the nipple;

(2) If the nipple has two flanges which are each placed on one of the sides of the open bottom of the screw cap, each flange constitutes a tight joint either in its carrying position or in its use position. In its carrying position the bottom of the screw-cap, which is suitably shaped, presses on the flanges of the nipple thus ensuring a double tightness or sealing.

,The invention will be better understood from the description which follows and by referring to the accompanying drawing merely by way of informatory but not limitative example in which:

Fig. 1 shows the device in its carrying position when using a nipple with a single flange; Fig. 2 represents the same device as Figure 1 but in its position of use;

Fig. 3 shows the device in its carrying position when using a nipple having two flanges;

Fig. 4 represents the same system as Figure 3 but in its position of use.

By referring to the drawing more particularly wherein the first modification has a nipple with a single flange, 1 isthe feeding-bottle, 2 is the screw cap, 3 the nipple and 4 the outer cup shaped cap.

The neck of the feeding-bottle is stepped inwardly towards its mouth and includes two threads 5 and 5' each on one step with one for the cap 2 and the other for the outer cap 4.

As will be seen on Figure 1, nipple 3 is extended through the center opening of the screw cap 3 so that when it is entered into the neck of the feeding-bottle, for its carrying position, the cap 2 will be placed on the neck in an upside-down position.

In such a position, the main part of the nipple and its shoulder close the neck of the feeding-bottle to effect the sealing.

Such sealing is increased by the bottom 6 in the shape of a truncated cone of the. cap 4 which presses from the inside to the outside on the lateral flange 3' of the nipple 3.

According to a second modification having nipple 7 with a pair of spaced flanges 7' and 7" providing a groove therebetween, the principle is absolutely the same, but the flanges 7 and 7", each placed on an opposite side of the open bottom 8. of the screw cap which is similar to the former mentioned cap forming two sealing joints in the carrying position (Fig. 3) or in the use position (Fig. 4) of the bottle.

In this species, the bottom 9 of cap 10 is so shaped as to press on the flange 7 in its carrying position.

In the two modifications described, in order to place the nipple in its position for use, simply unscrew the outer cap, withdraw the nipple from the neck of the bottle while holding the screw cap by its outer periphery and screw said screw cap on the threads 5 on the neck of the feeding-bottle.

Of course the present invention is in no manner limited to the two forms of embodiment described and shown, but on the contrary is extended to all species of shapes and dimensions.

Having thus described my invention what I claim is:

1. An improvement in infant feeding bottles comprising in combination a bottle having a neck stepped inwardly towards the mouth thereof, threads being formed on each step of said bottle neck, an internally threaded cap having an opening in the top thereof, a nipple having an open end with a lateral flange extending therefrom and extending through and from said cap opening with said flange positioned against the inner face of said cap top around said flange opening, said cap having said top thereof positioned on the mouth of said bottle with said nipple extending within said bottle neck in its storage position and capable of being inverted with said cap threads being in threaded engagement with one of said bottle neck threads with said nipple extending from said bottle neck for use in infant feeding ,and said ,-r1ip ple flange being positioned between said bottleneckand said.

cap forming a seal therebetween when s aidnipp le is in its position for use, a cup-shaped internally threadedjcap being in threaded engagement with thezot herof' sa id' bottle neck threads encasing said:first-mentioned:capw and; said nipple when in their storageposition and said cupshaped cap having an inwardly extending bottom bearing against said nipple flanged open end in its storage-posh tion forcing said nipple against said first-mentioned cap retaining said first-mentioned cap and saidnipple on.said bottle neck and forming a seal therebetween.

2. An improvement in infant feeding bottles as claimed in claim .1 wherein said inwardly extendingbottom of said cup-shaped cap has a truncatedcone configuration formed for extending. within said nipple flanged open end forcing said nipple flange and first-mentioned captogether against said bottle neck ensuring a seal therebetween.

3. An improvement in infant feeding bottles comprising in combination a bottle having a neck stepped inwardlytowards the mouth thereof, threads being formed on each step of said bottle neck, an internally threaded cap having an opening in the top thereof, an open endnipple having a pair of spaced lateral flanges adjacent said 4 open end providing a groove therebetween with said nipple extending through and from said cap opening and each of said flanges positioned on an opposite side of said cap around said cap opening, said cap having said top thereof positioned on the mouth of said bottle with said nipple extending within said bottle neck in its storage position and capable of being inverted and having said cap threads in threaded engagement with one of said bottle neck threads with said nipple extending from said bottle neck for use in infant feeding, a cup-shaped internally threaded cap being in threaded engagement with the other of said bottle neck threads encasing said first mentioned cap and said nipple when intheir storage position and said cup-shaped cap having an inwardly extending bottom bearing against said nipple flanged open end in its storage position forcingesaid nipple flanges against said first-mentioned cap retaining said first mentioned cup and said nipple on said bottle neck and forming a seal between said bottle neck, said first mentioned cap and said cup-shaped cap.
