Specification of Letters Patent'.
Patented Jan. 19, 1909.
Application filed. January 29, 190B. Serial No. 413,221.
Closures, of which ,the following is a speci# fication This inventitm relates to iuiprm'euents in metal caps or closures employed for'use on jars, bottles and other like vessels and also relates to improvements in the construction of such vessels and the said invention consists in the construction and arrangement of devices hereinafter described and claimed.
One object .of my invention is to provide bottle and the cap with coacting means to firmly seat the cap on the mouth of the jar or bottle.
In the accompanying drawings, Figure 1 is an elevation of the mouth portion of a vessel and a sectional view of one of my improved caps or closures about to be applied thereto. Fig. -2 is a sectional view showing the mouth portion of a vessel and one of my improved caps or closures in position thereon. Fig. 3 is a detail perspective view of the cap or closure. Fig. 4 is a detail sectional view showing a portionv of the cap or closure and also a portiony of a rubber packing ring or gasket. Fig. 5 is a similar view showing the closure applied to the mouth of a vessel and comprising the ring or gasket on and around the edge of the mouth of the vessel. l
In accordance with this invention, the neck 1 of the jar, bottle or other vessel 2 is provided on its outer side with out-standing spirally disposed screw flanges 3 and also with an outwardly extending annular circumferential flange 4 which is parallel with the ,outer or top edge of the mouth of the vessel.
A closure or ca 5 is formed from a single piece ot suitab e sheet metal and is provided with a fiange 6 to extend around the neck of the jar, bottle or other vesseland of sufiieient depth to bear at its lower edge on the flange 4 so as to firmly scat the cap or closure on the mouth and around the neck of the jur or bottle. The. said cap or closure is formed on its under side at a suitable distance 'from its periphery and at `a point coincident with the edge of the bottle or jar mouth with an inwardly extending tlange i" which presents downwardly or iu\\ardl \Y converging' sides which form a .uarrou` edge 8 to hear on the u )per side of' the paper or other packing disli 9 aud torce the .salue firmly on the edge of thennouth of the jar or bottle and cause that portion ot the pael;h ing disk which is. directly under the said flange to bear so closely on the edge ot the mouth of the jar or bottle as to prevent leakage. In the angle between the top or disk portion of the cap and the flange l5 hereof is a rentrant inset 10 which -forms an annular inwardly extending shoulder ll which forms in effect a portion of the cap ot' reduced diameter as compared with the [lange '6 thereof, said shoulder 1l or reduced portion of the capserving to engage the packing disk 9 and to turn down the edge thereof` around the mouth of the bottle and to com press the said down-turned edge portion of the said packing disk rmly between the nouth of the jar or bottle and the shouldered portion 11 of the cap, and thereby enhance the efliciency of the said disk t) as a ackingbetween the mouth of the jar or bottle and the inner side of the cap. 'The flange portion 6 of the cap is provided with inwardly `extending spurs 12` which coact with thescrew flanges 3 of the jar or bottle to firmly secure the cap 4or closure in place around the mouth of the ar or bottle, as will be understood. These spurs set portion of greater internal diameter than" the external diameter -of the mouth of the vessel, an outwardlfextending annular cir` cumicrential shoul erat the ower edge of said inset portion, and also having an ont- Wardl'y extending portion helowisaid Shoule derio clear the screw threads of the Vessel .and having. its lower edge provided vwith means to engage sneh screw threads, in cornbination with a packing element under such disk portion7 sach packing element being of greater diameter than the internal dialneter of the inset portion of the tlange and ap- 10 proxiniatelj equal in diameter to the internal diameter ot' the ontnardly extending annular circumferential shoulder at the lower edge of nach inset portion and initially engaged around ils edge by such shoulder for the Apurpose Set forth.
2, In combination with a vessel having a screw thread on the outer side of its -neek and further provided with a shoulder belenI y the screw thread extending around its neck and parallel with its mouth, a packing element of greater diameter than the inout-h of the vessel and placed thereon and a cap comprising' a (liek portion and a flange depending therefrom to extend around the neck of i the vessel at the mouth, saidange having an inset portion of greater internal diameter than the external diameter of the mouth of the vessel, an outwardly extending annular circumferential shoulder at the lower edge of said inset portion linitially engaging the edge of the packingv element and cansin said edge of the packing element to be turne down around the neck of the Vessel at the mouth and within the inset portion of thel cap flange, .said cap fiange also having an outwardl)Y extending portion below said Shoulder clearing' and spaced from t-he screw thread and having its lower edgeprovided wi th means to engage the screw thread.
