BOTTLE-CAP.

Application filed January 15, 1919.

To all whom it may concern:

Be it known that I, AMos L. FOREMAN, a citizen of the United States, residing in York, Pennsylvania, have invented certain Improvements in Bottle-Caps, of which the following is a specification.

The object of my invention is to so construct a closure for milk bottles and the like as to effectually prevent exposure of the contents of the bottle to contamination during storage or transit but permit ready withdrawal of the contents of the bottle when .desired, also Without such exposure.

This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in which- Figure 1 is a vertical sectional view of the upper portion of a milk bottle provided with a sealing cap in accordance with my invention, the section being taken on the line 1-1, Fig. 3, and showing the cap as it appears when the bottle is in storage or transit;

Fig. 2 is a similar view taken on the line 2-2, Fig. 3, but with the sealing cover removed, in order to illustrate the manner in which'the contents of the bottle are withdrawn without exposure to contamination;

Fig. 3 is a top view of the bottle shown in Fig. 1, and

Fig 4 is a similar view of a bottle having a cap with modified form of sealing connection between the same and the cover.

In the drawing, 1 represents the upper portion of the neck of the bottle having the usual recessed mouthwith cap seat at the base of the same, as usual. The closing cap 2 which rests upon this seat is of sufficient thickness to possess the. desired strength and rigidity and has formed in it two

openings

3 and 4, the opening 3 being the larger of the two and being intended for the insertion of a suction tube 5, as shown in Fig. 2, whereby the contents of the bottle or any desired portion of the same can be withdrawn without removing the cap 2 and also without undue exposure of said contents.

On the upper face of the cap 2 and surrounding the

openings

3 and 4 therein is a band 6 of adhesive material, and above the cap 2 and secured thereto by said band of adhesive material 6 is a cover 7 of parchment paper or other tough and flexible material, which has at each side a wing 8, these wings being at right angles to the band 6 and projecting slightly beyond the mouth of Specification of Letters Patent.

Serial No. 271,236.

the bottle so as to provide means whereby the cover 7 can be readily grasped and torn from the cap 2 when it is desired to release the same therefrom, the band 6 of adhesive material surrounding the openings 3 and l and serving, when the cover 7 is in place, to secure the same to the cap so firmly as to effectually seal the openings against the admission of air.

After the cover 7 has been secured to the cap 2 by the adhesive band (3, the cap and cover are dipped in a bath of melted paratlin wax, which serves not only to provide a waterproof coating for all accessible surfaces of the cap and cover, but, when cooled, also serves to unite the edges of the cap and cover and also the upper surfaces of the cap and the underside of those portions of the cover between the edges of the cap and the edges of the band 6, thus providing-an additional seal for the openings 3 and 4-, which seal can, however, be readily broken by pulling upon either of the wings 8, so as not to interfere with the tearing of the cover free from the sealing band 6 of the cap when the strain is exerted upon the latter.

The suction pipe 5 is preferably made of paper coated with paraffin or otherwaterproofing material, and when sealed in a sanitary envelop, such as that in which tooth picks are now served, it accompanies the jar of milk when the same is sold and thus provides for the sanitary serving of the milk as well as the sanitary packaging of the same while in storage or transit, the milk being protected from undue exposure during service and being also free from contamina tion by contact with the frequently unsanitary surfaces of glasses or cups into which it is ordinarily poured from the bottle and from which it is drunk.

Instead of providing the upper face of the cap 2 with a band of adhesive material extending across the cap and of a width greater than the diameter of the opening 3 said cap may have applied to its upper face, as shown in Fig. 4, circular bands 6 of adhesive material surrounding the

openings

3 and 4, and serving to secure the cover 7 thereto so as to seal said openings.

If the opening 3 in the cap is sufliciently larger in diameter than the tube 5 to permit inflow of air around the tube while the milk is being withdrawn through the same, the opening 4 in the cap may be dispensed with,

but it is preferable to fit the tube 5 snugly to the walls of the opening 3, in which case the air inlet 4 is necessary.

The

narrow bands

6, 6 of adhesive material surrounding the openings 3 and L in the cap are of a different character from the paraflin adhesive which unites those portions of the cap and cover outside of the limits of said

bands

6, 6 the paraiiin seal being of a readily frangible character while the adhesive 6, 6, although permitting separation of the cover from the cap when suiticient force is applied, preventing such separation under the strains to which it is subjected in the ordinary handling of a bottle.

In my claims I have, therefore, indicated this difference by characterizing the

adhesive

6, 6 as non-frangible, meaning thereby that it is not so frangible as the paraffin seal used in association therewith, and hence provides for a more secure sealing of the

openings

3 and 4 than would the paraffin seal alone.

I claim:

1. A milk bottle cap having an opening therein for the reception of a suction tube through which the contents of the bottle can be withdrawn, said opening being surrounded by a band of non-frangible adhesive material, and said cap being provided with a sealing cover normally heldfiin place thereon by said non-frangible adhesive material so as to seal the opening therein but which can be freed from connection with the cap when it is desired to uncover said opening.

2. A milk bottle cap having an opening therein for the reception of a suction tube through which the contents of the bottle can be withdrawn, said opening being surrounded by a band of non-frangible adhesive material, and said cap being provided with a sealing cover normally held in place thereon by said non-frangible adhesive material and by a frangible seal beyond the limits of the same, which latter seal is the first to be broken when the cover is withdrawn.

In testimony whereof, I have signed my name to this specification.
