My invention relates to a novel article embody ing a filled bottle having therein a brush or applicator which is secured to a sealing disk maintainedunder compression on the bottle neck by a closure cap. Still further, my invention relates to an article formed from a bottle sealing disk and an attached brush or applicator. My invention also relates to a novel sealing arrangement for a bottle.

In accordance with my invention, either manually or by an automatic filling machine, bottles are filled with a desired liquid. Following the filling operation, each bottle has disposed therein a brush or applicator which is secured to a sealing disk adapted to rest on the top surface of the bottle neck. Thereafter, by utilizing suitable mechanism, closure caps are automatically threaded to each bottle neck, each closure cap,

during the threading operation, moving into engagement with the bottle-supported sealing disk and compressing the same to eifectively seal the bottle.

, Various other features and advantages of my invention will become apparent from the following detailed description.

My invention resides in the art of filling and capping bottles, novel arrangements, articles and combinations of the character hereinafter described and claimed.

For an understanding of my invention, reference is to be had to the accompanying drawings, in which:

Figure 1 is a vertical sectional view, partly in elevation, showing a filled bottle having associated therewith a partially seated closure p;

Fig. 2 is a sectional view showing the closure cap of Fig. 1 in final seated position;

1 Claim. (01. -1404) 2 the bottle neck 2 to close the bottle l. The attached cap 6 holds the disk 4 seated on the upper surface of the bottle neck and retains the brush 5 within the bottle.

In accordance with the invention, empty bottles I, each without a brush and a closure cap, of the character described above or of such other suitable character as may be desirable pass in succession through an automatic'filling machine F, Fig. 3, of a character well known in the art. Each bottle I, as it passes through the machine F, is filled with a desired liquid and then, in suit-I able manner, the filled bottles I are passed toward a known automatic cap applying mechanism C which may be an attachment of the machine F and which comprise suitable mechanism for feeding closure caps 6 in succession toward the cap-' applying position.

With a supply of the above described attached.

disks 4 and brushes 5 available, one of them is associated with each filled bottle 5 while the latter is between the machines F and C. This may be done by an operator or by suitable mechanism. In so doing, each brush 5 is immersed in the bottle-contained liquid and the associated disk 4 is seated on the top of the bottle neck, Fig. 3. In this condition, each bottle I passes to the machine C which functions to thread to the bottle neck 2 a cap 6 threading operation, has neither a sealing disk nor a brush associated therewith. This cap 6, at the conclusion of the threading) operation, holds the disk 4 under compression on the top surface of the bottle neck to thereby seal the same. Thereafter, the filled bottles I, each hav ing a sealing disk 4, a brush 5 and a closure cap Fig. 2a is an enlarged, fragmentary view showing a feature of the invention; and

Fig. 3 is a diagrammatic view illustrating the method concept of my invention.

Referring to Fig. 1, I have shown a bottle or container 1 having an upstanding neck 2 provided'with exterior screw threads 3. Seated on the top of the bottle neck 2 is a sealing disk or washer 4 formed from any suitable material such, for example, as rubber or, preferably, from a 'more rigid rubber cork mixture as known in the art. The disk 4 may have a'central passage which receives one end of a brush or applicator 5, the latter being secured to said disk 4 in any desired manner as, for example, by suitable ad- 1 and 2, a suitable closure cap; 6 is threaded to As shown in Figs.

described disk 4 and having a central passage is.

inserted in a cap and, usually but not necessarily, held in position by adhesive.

In this condition, the caps and associatedliners are forwarded to bottling companies where the which, prior to the completed filled bottles are produced. At the bottling company, one end of a brush or applicator is passed through the central passage of each liner and secured adhesively in the above described well of the closure cap. As a result, there becomes available a supply of closure caps each of which has a liner or disk together with a brush. permanently secured thereto.

At the bottling company, there is an automatic filling machine and an associated automatic cap applying mechanism of the character referred to above. This apparatus functions automatically to fill the bottles and apply a closure cap to each bottle. However, the cap applying mechanism is incapable of handling a closure cap if it has a brush or applicator secured thereto as described above. Hence, if combined closure caps and applicators are to be associated with filled bottles, it is necessary that this be done manually by an operator. This is time-consumin and otherwise disadvantageous by reason of the fact that many bottles are returned by customers due to leakage which develops as a result of improper application of the closure caps to the respective bottles.

, As will be understood in. view of the foregoing description, it is a feature of my invention that the sealing disk and brush, as a combined unit, are associated with the filled bottle rather than with the closure cap. The latter, then, may readily be applied to the bottle by the automatic mechanism with resultant elimination of the disadvantages discussed above in. connection with the manual operations.

Closure caps utilizable in accordance with my invention have greater simplicity than those used in present practice. This follows due to the omission of the central well which is. provided for one end of the. brush. In addition, the manufacturer of the closure caps. does not insert the. sealing liners or disks therein. For these two. reasons, then, the cost of the closure capas supplied by the manufacturer is decreased.

Closure caps utilizable in accordance. with my invention may be of any type suitable for the intended purpose and inthis connection it will be understood, as stated, that no need arises for the provision of the aforesaid central well. However, preferably, I utilize a closure cap of the character illustrated which, above the threaded area 1 thereof, is shaped to form a circular flange or seat 8 connected at its periphery with a vertical circular surface 9 having an internal diameter only slightly greater than the external diameter of the sealing disk 4 which is to be associated with the closure cap. The height of this vertical surface 9 is somewhat greater than the thickness of the disk 4. The vertical surface 9 of the closure cap merges into a conical or beveled surface It and this, in turn, merges into an upper vertical surface I I.

The bottle I may be of known construction and, if so, the upper surface of the bottle neck 2 may have plane, circular configuration as indicated at l2 and this plane surface may be bordered by an outer beveled or frusto conical surface [3.

As will be understood, during the threading operation, the closure cap I moves downwardly with respect to the bottle neck 2 and the seal ingdisk 4. Eventually, then, the disk 4 takes aposition as illustrated in Fig. 1 Where it rests upon the flange 8.

When-theiclosure cap l is threaded to itsintended; seated. position as shown in Figs; 2 and 2a, the sealing disk 4 is held under compression against the bottle neck surface l2 to thereby seal the bottle opening. At the same time, the beveled surface ll] of the closure cap holds the outer portion of the disk 4 partially folded so that it engages the beveled surface I3 of the bottle neck and. extends around the peripheral corner I4: thereof with resultant enhancement of the sealing action. The space I la defined by the upper vertical surface ll of the closure cap is provided for the reception of the upper part of the disk 4 when the latter is disposed in its final seated position.

The hereinbefore described operation involving attachment of. a sealing disk 4, a brush 5 and a closure cap 6 to a bottle neck causes the sealing disk 4 to move into the closure cap beyond the flange 8 thereof. Subsequently, when a closure cap 6 is unthreaded and removed from itsv bottle, the disk 4 and brush 5 are also removed with the closure cap. This happens because the disk 4 seats upon the flange 8. Hence, the brush 5 is positively associated with the closure cap and the latter may be manipulated as desired to cause the brush 5 to perform its intended function. If desired, prior to the assembling operation shown in Fig. 3, the periphery of the disk 4 may have suitable adhesive applied thereto whereby said disk. 4, after completion of the described assembling operation, becomes more positively secured to the interior surface of the closure cap.

It will be understood that the invention is not to be limited to the precise threaded arrangement shown on the drawing. As Well, the threads may be partial or of other equivalent type.

While the invention has been described with respect to a certain particular preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claim to cover all such changes and modifications.

What is claimed as new and desired to be secured by Letters Patent, is:

An article of the class described comprising a bottle having an externally threaded neck, the upper surface of said bottle neck having an inner horizontal plane surface bordered by a frusto-conical surface, a fiat circular resilient sealing disk seatedv on the inner horizontal plane surface of the bottle neck, a brush disposed within the bottle, said brush being secured to and supported solely by said disk, and a closure cap threaded to the bottle neck to hold said .disk in sealing relation thereto, said closure cap diameter of the threads of said cap being less than the diameter of said disk, the latter being forceable past the threadswhen the cap is applied.
