M This invention relates to the bottling of liquids, and provides an improved method of, and apparatus for the aforesaid purpose. 3 v At the present time in the bottling of 5 liquids it is .necessary to leave the bottles either open to the atmosphere ,-or to open the same to the atmosphere at intervals, to allow the air displaced by the liquid to escape, the bottles and their contents being furtheraopenled to the atmosphere prior to the sealing of:

the bottles Which is a step performed independently of the filling operation.

' Disadvantages arising from the above mentioned operations, are that the filling of.

175 the bottles is retarded by the air therein, and

theopening ofthe bottles to the atmosphere 7 renders the bottles and the contents thereof, .such as milk, liable to contamination, and

a when dealing with liquids under pressure, results mum; loss of pressure, and the loss of gas usedin the manufacture of aerated bev-Z erages, and further it is necessaryto employ separate means for sealing thebottles. IThe present invention has the object of overcoming the disadvantages aboveenumerated, and in generalqa' view of providing a method of, andv apparatus, which will en- I able liquidsito be bottled more economically and under better hygienic conditions than those attendant upon present day bottling methods and apparatus.

charging the latter With liquid, so that the outlinterruption, Whether under pressure, or

simplyby gravity, While a further and i111 I portant feature ,Ofthfl invention, is that-the bottles and their contents-are not opened to 4 the. atmosphere, until such time as'the bottles are opened for use, sealingof the; latter being eifected'in the same appa'ratusas that from which the bottles are evacuated of \21112L11C1" K atmosphere.

If necessary liquidto he placed the bottle head;

latter Will-readily pass to the bottles Withcompanyingdrawings,vvherein:

pressure generated: by the gas mixed'wviththe liquid',, to the bottles.

filling and sealing of the bottles tovbecarried f 'out asbefore described, comprises a machine having mounted thereon a bottling h-eadfin communication With a source, of vacuum and} also p $0106 penedwhen required to a i reservoir containing'li quid tobebottledm p A support for the bottles, presses the V V mouths of the latter up into the head, Where-' f in is provided a ring or cushion of soft mate rial for: contacting-With'the bottle and sealing the entrance to the head, While operable vertically inthe latter, is a piston ad'apted to Contact with the bottle closure, "and' capable ofbeing used to force sealed bottles from the The pistoncan also be used for thepurpose l of lifting theclosure'to be .used in or on the bottle, clear of the mouth thereof While :the bottle is evacuated of air and 'c harged with liquidafter which-the closure is applie'dxtoq the bottl'eyand the latter ejected from- -the 1 An essentialyfeature of the invention, is the removal of air from theabottles beforez head vby the piston.
