MACHINE FOR SEALING BOTTLES, ETC.

Application filed December 5, 1923, Serial No. 678,699, and in France December 21, 1922.

This invention relates to a hermetic sealing under Vacuum of bottles, jars, boxes and other receptacles, by means of covers or capsules, made of metal or other suitable material, which are tightened on the neck of the receptacle, this mode of sealing being more particularly intended to be used prior to sterilization by means of heat, with a view to preserving all kinds of liquids, preserves, etc., such as and more particularly milk, meat extract, fruit, vegetables, etc.

As an example of carrying into effect the above process of sealing under vacuum by means of tightened-on capsules or covers, a sealing machine is described and illustrated diagrammatically in the accompanying drawings in which:

Fig. 1 is a longitudinal section of an apparatus for sealing receptacles by capsules or covers tightened-on under vacuum, the various parts being shown at the moment when the receptacle to be sealed, a bottle in that particular case, is about to be introduced.

Fig. 2 is a similar view, the various members being shown during the operation of sealing a cap under vacuum. 1

Fig. 3 is a general view of a machine for sealing under vacuum, comprising the above said apparatus.

Referring to the drawings, the apparatus for sealing under vacuum consists in principle of a vacuum box made of two parts 1 and 2, capable of sliding in each other, the hermetic sealing of the joint of this telescopic mounting being ensured by a suitable packing 3. The top part 4;, of the upper part 1 of the vacuum boX which is rigidly mounted, comprises a cylinder 5 on its inside, which cylinder is cast integral or attached thereto, its bottom 6 being attached to part 5 inany suitable manner and being provided with an opening 7; the centre of the said top part 4; is also provided with an opening surmounted by a guiding sleeve 8 in which slides a rod 9 of round or rectangular section for instance, ended at that extremity which can be displaced in the cylinder 5, by a transverse bar 10 sliding in a mortise 11, longitudinally provided in a solid block 12, which is integral or is at mortise 11, and the inner wall of the cylinder 5, integral with the top part 4: of the fixed part 1 of the vacuum box, on which ring bear the ends of the transverse head 10 of the rod 9, the said ring 13 resting upon a rubber washer 14: which is itself supported upon the rim formed by the bottom 6, theopening 7 of which is intended to allow a free passage for the neck of the receptacle, a bottle 15 for instance, provided with its cap or sealing cover 16 to be tightened-on under vacuum, the said receptacle 15 being partly engaged in the vacuum box through an opening provided in the bottom 1? of the movable part 2 which is provided with a resilient washer 18 against which the receptacle is pressed, and towhich an upward movement is imparted, thus ensuring a hermetic sealing of the joint at the shoulder of the bottle, and causes at the same time by its upward movement, the sliding of the part 2 inside the fixed part 1 of the vacuum box, until the neck abuts against the solid block 12, the plug of the capsule or cover 16, being then pressed between them.

The conduit 19 of a valve box 20, leads to the top of part 1, which conduit permits a vacuum to be obtained in the vacuum box and in the space left in the neck of the receptacle 15 above the liquid or substance to be preserved, as the capsule 16 which simply rests upon the neck does not prevent such a communication. 21 and 22 are valves for operating the vacuum and the inlet of air in the vacuum box when the sealing under vacuum is effected. I

This operation is carried out in principle according to the present invention and by means of the above apparatus in the follow ing manner.

The receptacle 15, with its capsule or cover 16 simply slipped over and resting upon the neck, is introduced. inside the vacuum box through the opening of the bottom 17 of the sliding part 2, the joint with the receptacle being hermetically sealcdby virtue of the resilient washer 18, the neck of the receptacle extending through the opening 7 of the bottom 6 of the central cylinder 5 01 the fixed part 1 of the vacuum box, as shown in Fig. 1.

A more or less slow upward movement being imparted to the receptacle, which movement carries with it the movable part 2, a vacuum is produced inside the vacuum box during the said upward movement, so that a vacuum exists inside the whole of the box and inside the receptacle 15 to be sealed, at the moment when the neck of the receptacle abuts against the central solid block 12, the bottom of the cap or cover 16 being then caught and pressed between the said block and the neck,asshov.*n in Fig. 2.

At that moment, the vacuum being still maintained in the vacuum box, a downward motion is imparted to the rod 9 which carries with it the head 10, which head slides in the mortise 11 of the block 12, and which rests against the ring 13 and causes the latter to come down and to compress the rubber ring let which is thus distorted or forced out of shape and presses the flange of the capsule or cover 16 under the action of the pressure which is transmitted to it, and causes it to penetrate and to be moulded in the grooves or under the beading provided as usual or for this purpose at the end of the neck of the receptacle 15, the capsule or cover being thus tightened on the neck of the receptacle, the sealing by tightening-on being thus carried out in the vacuum.

The tightening-on operationbeing ended under vacuum, the valve 21 of the vacuum machine is closed and the valve 22 is opened allowing the outside air to penetrate into the vacuum box, whilst the sealed receptacle is lowered and can therefore be withdrawn from the bottom 17, the movable part 2 of which is brought to its original position by any suitable means.

Of course the ti ghtening-on member which is represented here by the compressed rubber washer and which has already been used in ordinary sealing machines working in the atmospheric air, may be replaced by any other means or devices for tightening-in, as this has only a secondary importance in the method of sealing under vacuum by tightening-in.

In order to ensure the successive working of the various members of the said vacuum box and the various operations which are necessary for carrying the sealing process into effect, a machine for sealing under vacuum by means of tightened-on covers may be formed as follows and as illustrated in Fig. 3.

A column 23 carried by a pedestal 2 1, comprises two arms 25 and 26, the first of which acts as a support for the apparatus for sealing under vacuum and which has just been described, and the members forproducing the vacuum and for carrying out the tightening-in operation, the second arm 26 supporting and guiding a plate 27, on which is placed the receptacle 15 to be sealed.

The machine is operated by means of a pedal 28, which acts simultaneously. upon rods 29 and 80, the first of whichis keyed upon the oscillating axle of the pedal 28 and carries at its upper end a roller 31, which during the oscillating movement of the said rod lifts a cam 32 of suitable shape and therefore the sliding support 36, of the plate 27, through the intermediary of the rods 33,

3 1 and 35 which su )ort is raised and brin s i 3 D pedal 28, the second rod 30 acts upon a lever 37 which is pivotally mounted upon the bracket 25, and which successively operates the valve 21, which places in con'mumication the vacuum box with the vacuum-producing machine and which may be of any type, a suction pump for instance, and operates afterwards by a continuous action of the pedal 28, which has ceased to lift the cam 32 owing to its suitable shape, the rod 9 of the transverse bar 10, which through the metallic ring 13 and to the tightening-in rubber ring 14, thus compressed all around the side wall or flange of the cap or cover 16, produces its sealing upon the neck, as shown in Fig. 2.

By freeing the pedal. 28, the lever 37 swings in the opposite direction in order to re-take its first position, thereby disengaging the rod 9, which effects the tightening-on operation, and operates the rod of the vacuum valve 21, for the inlet of air into the vacuum box, and closes the valve 22 b means of a shackle 3.8, fixed at its en thereby permitting the bottle 15 or other sealed receptacle, to leave the vacuum box and come down with the plate 27 which carries it.

In the operation of this improved machine a bottle or other receptacle to be sealed will be placed on the plate orreceptacle support 27 with its neck, having a sealing cap thereon, in the position shown in Fig. 1. The plate or support 27 is then lifted by the treadle-operated means hereinbefore described, and this lifting of said support forces the shoulder of the receptacle against the elastic washer 18, thus making a tight joint between the shoulder of the receptacle and the movable part of the vacuum box while the receptacle 15 is beingraised to the position shown in Fig. 2. Thecontinued movement of the treadle-operated mechanism next causes the exhaust or vacuum valve to be opened for the vacuum exhaust of the receptacle,'and instantaneously following this operation the head 10 descends for sealing the cap, as shown in Fig. 2. It is to be understood that the whole operation of lifting the receptacle to be sealed, exhausting the vacuum chamber and scaling the cap is practically an instantaneous one,

and that the pressure of the shoulder of the receptacle against the elastic washer 18 Will be suflicient, during this operation, to keep a tight joint between said washer and said shoulder to maintain a proper vacuum in the chamber of the vacuum box until the sealing of the receptacle is effected.

Here too, the construction of a sealing machine for instance, by means of a cap or cover tightened-on under vacuum, may comprise modifications for Working of the vacuum box it being understood that a simul taneous sealing of several receptacles may be carried out according to the same principle, and that it is possible. to introduce the whole receptacle to be sealed in the vacuum box, the bottom 17 of the movable part 2 oi which comes then for instance, in contact with the plate 27, a hermetic sealing joint between the said bottom and the plate being ensured, of course, by means of a suitable packing 18.

Having now particularly described and ascertained the nature of my said invention and in What manner it is to be performed, I declare that What I claim is:

In a bottle sealing machine, the combination With a telescoping box constructed to receive a bottle neck With a sealing cap thereon, said box comprising fixed and movable parts, the latter sliding Within the former, means Within said box for compressing said cap around said neck to seal the receptacle, said movable part having an opening through Which the neck of the bottle may pass, said opening being lined by an elastic Washer to afford an air-tight joint around the shoulder of the bottle, and means for lifting said bottle and causing the movable part of said vacuum boX to be raised to scaling position.

In testimony whereof I affix my signature.

JOSEPH TALANSIER.
