Original application filed; June 1, 1918, Serial No. 237,831.

0 all whom it may concern:

Be it known that we, l/VILLIAM 1V. SIMON- sort and LEWIS V. D. BLAIR, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Stoppers, of which the following is a specification. The invention relates to stoppers such as may be advantageously employed with heatinsulated containers of the kind covered by our prior application #237,831, filed June 1, 1918, of which the present applicatlon 1s a division.

The stopper herein claimed is made of glass or other vitreous and frangible material, and is adapted to eifectuate the closure and complete the insulation of a heat-1nsulated receptacle.

The invention will be best understood by referring to the accompanying drawing in which- Figure 1 is a vertical section of the upper end of a heat-insulated receptacle, and of a stopper embodying the invention, and D Figure 2 is a similar view showing a modilied form of the stopper.

Referring to Figure 1, 1 is the outer jacket, and 2 is the container of a heatinsulated vessel. The container 2 is provided with a horizontal flange 3 extending over the upper edge of the outer jacket and resting on a heat-insulating bond 3* of heat-treated lac, or other suitable material, all as described in our prior application.

The heat-insulated receptacle shown in Figure 2 is of the same construction as that shown in Figure 1, and this construction, per se, forms no part of the invention claimed in this application. A screw-threaded collar 4. surrounds andconceals the seal 3, and carries a flange 1 extending over the flange 3. These features also are covered by the original application.

The novel stopper which embodies the invention herein described, consists of a hollow body 6 of vitreous material which is of greater diameter than the mouth of the container 2, and is provided with a shoulder 6 resting on the top of said container, and with a contracted portion disposed below said shoulder and of sufficiently small dimensions Divided and this applieaton filed March 22,

to readily enter'the mouth of said container. The stopper has a neck 6 and upon the upper edge of this neck rests a cover 7 which is bonded thereto by heat-treated lac 7 or other suitable substance which will ensure a firm union of the parts. The material employed'is fully described in the original applioation, and requires no detailed description herein.

The cover is provided with an exhaust opening which is closed by a mass of heattreated lac, or other adherent substance, 8-, over which a plate 9 may be placed to protect the sealing material. Also a protective cap 10 may be crimped over the edge of the cover 7 to afford further protection to the seal, and to obscure and protect the bond 7*. It will, of course, be understood that the exhaust opening should be unclosed until the stopper is substantially completed, so that air may escape and internal pressure such as might disrupt the closed stopper will not be produced.

The parts shown in Figure 2 are similar to those of the stopper shown in Figure 1, but in this constructionthe stopper is devoid of the neck 6 and the cover 7, and the pro.- tective cap is erimped over the shoulder 6, as shown.

The stopper is held to its seat by a drinking cup 11 having means for engaging the. screw threads of the collar 1.

' Silvering may be employed to reflect thermal radiation and will be applied to the in-. sidewall of the stopper before the stopper is closed, but the silvering is unaffected by the heat-treatment to which the bonding ma-. terial is subjected, this bonding material being formed under such low temperature conditions that the adherency and the reflective properties of the silvering remain unimpaired.

Having thus described our invention, what we claim, is:

1. A multi-part heat-insulating hollow stopper having a hermetically sealed and, interiorally silvered glass body portion provided with a closed bottom and an upstand ing neck.

2. A heat-insulating hollow multi-part stopper including a frangible body portion provided with a contracted lower end forming a shoulder, and with an upstanding open neck and a closure bonded to said neck.

3. A heat-insulating hollow frangible stopper in which the air pressure is sub-non mal, provided with a closed bottom and with an exhaust opening closed by a seal of material adherently united to the wall of said opening, and with a reinforcing plate for said seal.

4c. The combination with a heat-insulated receptacle, of a heat-insulated hollow closed stopper, the space within said stopper being enclosed by a plurality of parts, and including a body portion extending into the neck of the receptacle and having a non-corrodible outer surface, said stopper having also a determinate seat which extends over and is supported from the lip of the receptacle, and having a cover provided with an opening in its top for the reception of a plug of material dissimilar in character from that of the cover.

5. The combination with a heat-insulated receptacle, of a heat-insulated hollow closed stopper, the space within said stopper being enclosed by a plurality of parts, and including a body portion extending into the neck of the receptacle and having a vitreous outer surface, said stopper having also a determinate seat which extends over and is supported from the lip of the receptacle, and having a cover provided with an opening in its top for the reception of a plug of materialdissimilar in character from that of the cover.

6. The combination with a heat-insulated receptacle, of a. heat-insulated hollow closed multi-part stopper, the space within said stopper being enclosed by a plurality of parts and the bottom of the stopper extending into the throat of the receptacle, said stopper having a non-corrodible outer surface and including a determinate seat for supporting the stopper at a predetermined altitude within said throat, an inverted drinking cup removably attached to said receptacle for exertlng pressure on said stopper, and a cover for said stopper which is disposed at a predetermined altitude relative to said seat. 7. A heat-insulating multi-part stopper including a frangible body portion provided with a contracted lower end forming a shoulder, and an open upper end, and a closure sealed to said upper end.

8. The combination with a heat-insulated receptacle having a drinking cup for exerting pressure on its stopper, of a multi-part hollow heat-insulated stopper having a cover provided with an exhaust opening in its top, a hollow body portion and a closed bottom extending into the neck of the receptacle, the space within said stopper being enclosed by a plurality of parts, said stopper having a determinate seat which extends over and is supported by the lip of the receptacle, the

body portion of the stopper having a vitreous outer surface and the opening in the cover being closed by a plug of material of different character from that of the cover.

9. A heat-insulating hollow multi-part frangible stopper for a heat-insulated receptacle, said stopper having a circumferential shoulder for engaging the mouth of said receptacle and an upstanding neck, and a cover for closing said neck, said cover having a marginal flange encircling said neck and material disposed between said cover and said neck for sealing the space there between.

10. A heat-insulated hollow multi-part stopper having an upstanding open neck and a frangible body portion having a circumferential seat for sustaining said stopper in a heat-insulated receptacle, and a metallic cap having a marginal flange encircling said neck.

11. A hollow frangible heat-insulating stopper having a body portion provided with a shoulder for sustaining said stopper above the mouth of a heat-insulated receptaclc, and also provided with an open upstanding and narrow neck and a closure externally secured to said neck.

12. A frangible heat-insulating stopper having a hollow body portion adapted to rest upon the mouth of a heat-insulated receptacle, and provided with a relatively narrow upstanding neck carrying a closure externally secured thereto, said stopper havingalso a depending portion which is adapted to enter the mouth of such receptacle, said depending portion being hollow and open to the space within said body portion.

13. The combination with a heat-insulated receptacle, of a hollow multi-part frangible stopper for the container of said receptacle, said stopper being substantially opaque as regards radiant heat and provided with an external hollow shoulder which shoulder is adapted to rest upon said container at its upper portion to thereby sustain the stopper somewhat above said upper portion, and a drinking cup secured to said receptacle and surrounding, directly bearing upon and enclosing the upwardly-extending part of said stopper.

14. The combination with a heat-insulated receptacle, of a hollow multi-part frangible stopper for the container of said receptacle, said stopper including an upstanding opentop neck, which is closed by a cover having a flange externally secured to said neck, said stopper being substantially opaque as regards radiant heat and provided wlth an external hollow shoulder, which shoulder is adapted to rest upon said container at its closing the upwardly extending part of said stopper.

15. A heat-insulating mnlti-part stopper including a frangible body portion, provided with an upstanding open neck, a closure, and a seal disposed between said neck and said closure.

In testimony whereof We alfix our signatures in the presence of two wltnesses.
