[0023] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. An effort has been made to use the same reference numbers throughout the drawings to refer to the same or like parts.

[0024] Figures 1 and 2 show a first embodiment of a liquid dispenser 10 according to the present invention. As illustrated in Fig. 2, the liquid dispenser 10 includes a liquid container 40 that is configured to fit within a support member 30. The liquid container 40 and the support member 30 are enclosed by a cover 20. Both the support member 30 and the cover 20 provide thermal insulation for the liquid container 40, allowing the liquid dispenser 10 to be used for both hot and cold liquids.

[0025] The support member 30 in this example comprises an integrally formed frame with a cavity 32 configured to receive and enclose the side wall and bottom portions of the liquid container 40. In this way, the support member 30 thermally insulates the liquid container 40. As illustrated, the support member 30 may be shaped as a box to define an overall box shaped dispensing device 10. However, the support member 30 (and the cover 30) can have different sizes and shapes. Similarly, although a box shaped liquid container 40 and corresponding box-shaped cavity 32 is utilized in the illustrated example, the liquid container 40 may have other sizes and shapes.

26] The liquid container 40 may be placed within and removed from the support member 30, and the liquid container 40 and the support member 30 together may be placed within and removed from the cover 20. The support member 30 thus serves to enclose the liquid container 40 and to provide overall structural rigidity to the dispensing device 10.

[0027] Preferably, the cover 20 according to the invention completely surrounds the support member 30 and the liquid container 40. Preferably, the cover 20 is formed of a flexible, lightweight and durable material, such as a nylon fabric. Other materials may be used, such as polyester, PVC, and cotton, or a combination thereof. Preferably the flexible cover is lined with a reflective vapor barrier material, as known in the art. Such materials may include, for example, a vinyl-backed metallic sheet.

[0028] In this example, the cover 20 includes a handle 24 to facilitate transport of the liquid dispenser 10. The cover 20 also includes a top portion 21 that opens to receive the support member 30. The top portion 21 may be held closed with attachable Velcro portions 22 and 28, or other latching members known in the art. [0029] Also in this example, a sealable orifice 42 is provided on the top of the liquid container 40 to receive liquids to be dispensed. Further, a spout 26 extends from the cover 20 and connects to an opening 44 in the liquid container 40 through an opening 34 in the support member 30. Other means for dispensing liquid from the container may also be utilized.
