BOTTLE AND CLOSURE.

Application filed May 10,

llhe present invention relates to bottles and closures therefor, and aims to provide an improved sanitary closure construction, in which the mouth 01' the bottle is eii'ectively sealed and the surrounding neck portion oi the bottle is protected againstcontamination in the handling or the bottle.

In the embodiment or the invention in practice, 1 provide a bottle construction adapted to aliord an exterior seat for the. bottle cap or closure at some distance below the mouth of the bottle, and for cooperating with this improved type of bottle 1 provide a novel form of cap or closure element which is adapted to etl'ect the usual sealing function directly at the mouth or the bottle, and also to cii'ect a seal at the exterior or the bottle in conjunction with the exterior seat there provided, and at the same time protect this portion or the neck of the bottle, adjacent to its mouth, from direct contact in the handling of the same.

WVit-h this general object in view, I will now more fully describe the invention in de tail, by reference to the accompanying drawing illustrating one form of construction which I have devised for embodying the same, after which those features and combinations deemed to be novel will be particularly set forth and claimed.

In the drawing- Figure 1 is a view in side elevation, illustrating a bottle and closure construction embodying the present invention;

Figure 2 is a central vertical sectional View, taken on the line IIII 01 Figure 1;

Figure 3 is a plan view of the bottle, with its closure or cap member removed; and

Figure 4 is an inverted plan view or the cap or closure member.

Referring now to said drawing in detail, this shows an ordinary type of receptacle in the form or a bottle 5, such as used for hottling milk or the like, and which is formed with the neck portion 6 terminating in the mouth 7 surrounded by the usual annular seator depression 8, against which is press fitted the usual form or fiber or cardboard cap (not shown) for sealing the bottleand its contents.

In the improved construction, I form the neck portion of the bottle with an annular external enlargement 9 at some distance below the mouth 7 otthe bottle, in order to provide an externahshallow groove or depression 10 extending entirely around this enouter mar erial No. 108,045.

toembrace the margin of the mouth 7 of the bottle, while the central portion '12 has its 1 iitted against the seat or depression 8, as shown in Figure 2. The beaded or rolled portion Id of the cap member also carries an outer tapering portion 15 adapted to embrace the tapering portion 11 or the neck of the bottle betweenits mouth and the enlargement 9. This outer portion 15 ot' the closure inen'iber terminates in an outwardly projecting lip or flange 16 which is designed to htsnu'giy within the groove or depression 10 with which it eli'ects a tight external seal entirely around the bottle.

The enlarged portion 9 is provided with a notch 17 communicating with the groove 10, to permit the insertion of a suitable pointed instrument for engagement with the margin or lip portion 16 of the closure me1nher, in removing the same from the bottle.

The unsanitary character of the usual form of bottle, such as used for milk and the like, and the caps provided therefor, is well known and understood. The contents of the bottle seep out around the mar in of the cap, torming'little sumps that attract flies and other insects and resulting in a quite unsanitary condition and with no protection against the milk which has seeped out reentering the bot tle after it has become thus contaminated. N or is any protection at all aiiorded the neck portion of the bottle during the handling of the same before thecontents aroused.

In my improved construction, these objectionable features are overcome, and moreover new advantages are obtained with a view toproviding an entirely safe and sanitary closure means. of the bottle as effectively sealed as in the usual construction, by means of the central portion 1270f my closure member, but the neck portion'is both sealed and protected entirely from the seat or depression 8 to the Not only is the mouthinated. But, in addition to this feature, the

main advantages of this improvedform of construction are the safeguarding against the chance of impurities finding their way into the contents of the bottle and the protection of the margin of the bottle adjacent to its 'moutlragainst contamination by direct contact with the hands of the person on its way to the consumer. That is to say,-the exterior of the neckportion of the'bottle between the mouth and the groove 10 is entirely protected by the outer portion 15 of the cap member,. so that this is preserved in a perfectly sanitary and safe condition, an advantage of obvious importance when it is considered that it is common practice to simply remove the cap, or closure member and drink the contents'directly from the bottle, under which circumstances the need for cleanliness of the exterior portion of this part of the bottle and entirely around the same cannot be overemphasized.

It is apparent that not only maythe im memes proved cap or closure member be readily and cheaply manufactured but the bottle itself with the modification thereof needed for adapting its use to the improved form of closure member may be manufactured as readily and. economically as the form of bottle in present use. While I have illustrated and described what I regard as the preferred form of embodiment of the proposed improvements, I desire to reserve the right to make such changes and modifications as may claim.

VVhat-I claim is:

A bottle having its mouth formed with an annular cap seat or depression,- the neck of the bottle'h'aving an external enlargement spaced some distance below said mouth and fOlDlGClWlth an annular groove,- said neck being tapered between said enlargement and the mouth ofthe bottle, anda cap closure member having its central portion depressed or counter-sunk 'to fit against said cap seat or depression and its outer portion embracing the neck of the bottle between its mouth and said enlargement, the margin of said v member being formed with a lip seated in said groove.

In witness whereof I hereunto affix my signature.
