King-@ecley Thermos Co., Ann Arbor, Mich, a corporation oi Michigan Filed Apr. 8, 195?, Ser. No. 804,956 3 Claims. (6i. 21513) This invention relates to removable closure means for vacuum bottles and, more particularly, to a closure assembly which includes a seating element positioned on the neck of a vacuum bottle filler and a removable stop per element adapted to be threaded onto the seating element to close cit the opening in the filler. The new assembly is characterized in that the seating element includes special sealing means, separate from its threads, which are adapted to engage the stopper element to co operate in effecting the seal.
Vacuum bottle closure means have been developed heretofore which include a separate annular member secured to the end of the bottle between the casing and the eck of the filler to provide means for attaching a removable stopper which closes oil the opening in the filler. in conventional designs, the outer circumferences of such an annular member provides a seat which receives a pcripheral flange on the stopper element to hold the stopper element in place. The stopper element is usually snapped into this seat. Thus, the elements of a two-piece closure assembly of this type act together such that the removable element can be attached to the affixed annular element to seal the bottle.
it is the purpose of the present invention to improve upon vacuum bottle closure means of this design by providing a closure assembly wherein the elements cooperate to effect a more dependable seal. In the contemplated closure means, the annular seating element afiixed to the bottle does more than merely provide means for receiving the removable stopper element. t. also includes separate sealing means which are adapted to coact with the stopper element to provide a double-sealing effect. Thus, fiuids contained within a vacuum bottle filler sealed according to this invention are confronted between the removable stopper element and the afiixed seating element with a continuous circumferential seal which is independent of the threaded attachment between the elements.
According to the invention, the novel closure assembly is contemplated in combination with a vacuum bottle which includes a filler having a neck portion defining a smooth, generally cylindrical opening. The closure means comprise an annular seating element of resilient material disposed about said neck portion in sealing engagement therewith. External threads are formed on the outside diameter of the seating element. A stopper element of resilient material is also included having an internally threaded circular peripheral fiange portion which is adapted to be received by the external threads on the seating element. This stopper element includes a substantially cylindrical, central plug portion which is adapted to extend into and seal the opening in the neck portion of the filler when the stopper element is threaded onto the seating member. Annular sealing means are also included in the seating element which are independent of its external threads and are adapted to engage the stopper element to cooperate in eifecting the seal.
Preferred embodiments of the new closure assembly are described hereinbelow with reference to the accompanying drawing, wherein FIG. 1 is an elevation partly in section of: the upper portion of a vacuum bottle employing the closure assembly of the invention;
FIG. 2 is a fragmentary elevation partly in section of the removable stopper element of FIG. 1;
FIG. 3 is an elevation in the section of the upper portion of a vacuum bottle employing another form of the closure means of the invention; and
FIG. 4 is an elevation in section of the upper portion of a vacuum bottle employing a third form of the closure means or" the invention.
Referring first to FIG. 1, the vacuum bottle includes an outer cylindrical casing it) engaging at its top and ex ternally threaded collar 11 which is adapted to receive an internally threaded cup-like cover element (not shown). Around the upper circumference of the threaded collar 11 is an edge portion 12 extending substantially radially inwardly and defining an opening in the casing.
Positioned substantially coaxially within the casing it) is a thin, double-walled glass filler 14. The filler includes a neck portion 15 at one end thereof defining a smooth generally cylindrical opening 16 which communicates with the interior of the tiller. At the bottom of the casing, the lower end of the filler 14 is positioned by any conventional means in such a manner that the neck portion 15 extends up to the opening defined by the edge portion 12 of the collar 11. It is the function of the contemplated closure assembly both to secure the neck portion 15 of a filler 14 in its coaxial position at the open end of the casing 10 and to prevent fluids contained in the filler from leaking out of the bottle or into the space between the casing and the filler.
An annular seating element 18 is included in the assembly having a base portion 1 .9. The seating element 18 is formed from a resilient material such as plastic, natural or synthetic rubber, or a similar elastomeric composition. The inside diameter of the base portion 19 is normally slightly less than the outside diameter of the end of the neck portion 15 of the filler 14, so that it must be expanded to receive the neck portion of the filler, in sealing engagement therewith, as shown in FIG. 1. The edge portion 12 of the collar 11 overlies the outer surface of the base 1? of the seating element when the bottle is assembled. By this construction, the base portion 19 locates the neck portion 15 of the filler 1d concentrically at the open end of the casing and also creates a seal around the neck portion of the filler to prevent leakage of fluids into the space between the casing and the filler.
The seatin element 18 has integral external threads 21 formed about its upper portion .22 above the casing and filler. An integral, circular flap 23 extends inwardly and downwardly from the upper portion 22 of the seating element in such a manner that the lower end of the flap extends into the opening 16 of the filler. Because of its normal resiliency, the fiap 23 presses against the neck of the filler with suflicient force to form a seal.
The removable member of the new closure means consists of a stopper element 25 of resilient material of the same composition as the seating element 1%. A circular peripheral flange 26 is provided around the circumference of the stopper element 25 and has internal threads 27 formed on its inner wall. These internal threads 27 are adapted to engage the external threads 21; on the seating element 18. The stopper element 25 includes a plug 29, which is connected to the flange 26 by a web 3t? and projects downward therefrom. The plug 29, in the embodiment of FIG. 1, is of hollow construction opening outwardly on the top of the stopper element.
It is intended that the lower end of the plug 29 extend downwardly to such an extent that it enters into the opening 16 in the neck of the filler when the stopper element 25 is fully threaded onto the seating element 18. As seen in FIG. 2, an annular flexible lip 32 is provided at the lower end of the plug 29 and extends substantially radially outward from its lower edge. An G-ring member 33 of 3 resilient material encircles the lower end of the plug 29 and is held in position by the lip 32.
When the stopper element 25 is threaded onto the seating element 18 to seal the vacuum bottle, the lip 32 on the plug 29 rides over the ilap 23 on the seating member l3 and is bent around the ring 33 as shown in FIG. 1. Because both the flap 23 and lip 32 are formed of resilient material they deform when squeezed against one another to provide a particularly effective seal.
Turning now to the embodiment of FIG. 3, the upper portion of the vacuum bottle shown includes a conventional casing as and filler ii. The casing supports a collar 42 spaced from a neck portion 43 on the filler by means of a seating element 44. Included in the seating element 44 are external threads 45 and a flap id extending inwardly and downwardly into the opening defined by the neck portion 43 of the filler. A removable stopper 43 is provided having internal threads 49 formed on the outer flange Sll to be received by the external threads 45 on the seating element 44. The stopper also includes a central hollow plug 52 adapted to extend into the opening in the filler when the stopper is threaded onto the seating element. As in the previous embodiment an -ring 53 encircles the lower end of the plug portion 52 and is held in position by a circular, flexible lip 54. When the plug 52 enters the opening in the neck of the filler, the lip 54 cooperates with the flap 46 to effect a particularly dependable seal as before.
In the embodiment of FIG. 3, the plug 52 of the stopper 48 is connected to the flange 56 by means of a web 56 which extends unbroken across the top of the stopper. Hence, the hollow plug 52. is closed oil at its outer end and defines a completely enclosed insulating cavity 57. This modification permits fluids contained in the filler to be maintained at the desired temperature relative to that of the ambient air for greater periods of time. In the form of the invention illustrated in FIG. 3, the plug 52 is separate from the web 56 and is attached thereto by a flange 58.
In the embodiment of FIG. 4, the vacuum bottle again includes a casing mounting a collar 61 surrounding a neck portion 62 of a conventional filler 63. The neck portion 62 of the tiller is spaced from the collar 61 by means of a base flange 64 of a seating element 65. In this embodiment, the base flange 64 is gripped by a crirnped rim 66 on the collar 61, rather than by being squeezed against the neck portion of the filler.
The seating element 65 prevents leakage of fluid into the space between the casing and the filler by means of a resilient primary flap 63 and a secondary flap 69 extending from the upper and lower ends of the seating element into sealing engagement with the top and outside surfaces respectively of the neck portion 62 of the filler. To provide the desired double-seal the upper periphery of the seating element 65 is shaped to define a sealing edge 71. Again, external threads 72 are formed on the outside diameter of the seating element 65.
A removable stopper element 74 is adapted to be thread ed onto the seating element 65 by means of internal threads 75 formed around the inside of an integral flange l portion '76. The stopper 74 includes a central hollow plug portion 77 which is connected to the flange '76 by a Web 78. The open end of the plug 77 may be closed by a cap '79 to improve its insulating characteristics as in the embodiment of FIG. 3.
When the stopper 74 is threaded onto the seating element 65, the plug 7'7 is forced into the opening in the neck of the filler, as shown in FIG. 4, and the sealing edge 71 on the seating element engages the underside of the Web 78. Hence, the seating and stopper elements in this embodiment again cooperate to provide sealing means which are separate of the threaded attachment means. Since these elements cooperate at a point removed from the filler, however, the seating element 65 is equipped with the primary and secondary flaps 6t; and 69 to engage the filler outside of the opening to prevent leakage of fluid into the space between the casing and the filler. 7
