Referring to the drawings, A is a common .glass bottle, made with a lip or solid projection around its niouth,in the usual manner; B, the

metallic cap, and G thetwo-part collar.

' vThe cap B is a hollow cylinder closed at one end, and has afiat cylindrical piece of cork,cl, or other similar elastic material, cemented or otherwise secured within it at the closed end, vsothat 'when it isplaced over the .month of the said bottle the-cork shall entirely cover its said mouth, and has-also screwthreads e.

ynietalxin the forni oi" av shrt hollow cylinder `operiat both ends, with screw-threads f around its periphery to -niatch'with those @which arel"` on the inner side of the" cap, and aiso with two small projections, gg, at 'its lower edge. It is then sawed diametrally in two parts by a single straight eut, as shown in `Figs. 1 and 3, or by two oblique cuts, as shown in Fig. f1, the latter being preferred, as it brings the severed threads `in juxtaposition when the two parts of the saidcollar are held by the fingersaroundthe neck ofthe bottle. The diameter of the inside of this collar is somewhat greater than thatoil the'neck ofthe bottle where it is applied, so asito admit of the expansion of .the latterl by boiling-heat, and that ofthe outside sufiicient to jproject -the screw-.threads thereon beyond the llip 'h 'of the bottle 'when A'applied to sa-me, while Vat A,the same time vits .upper edge comes inl `contact with the under 7e'dge'of the sai-d lip h, and -thus prevents -the collar from being drawn over the` lip, as seen g. Infconstructing the cap-B it maybe cast'of any/'suitable soft met-abermay be made of tinplate, and? the""screwthreadse subsequently castaround ontheinner side of vthe-.samein a well-known. manner.
