Abstract
Description
- This application claims the benefit of U.S. provisional Ser. No. 60/175,410, filed on Jan. 10, 2000.
- This invention concerns drinking vessels and more particularly drinking vessels designed to keep a chilled beverage cold during the period when the beverage is being consumed by a user of the vessel. Insulated jackets have been used in the past, but in seeking further improvements in keeping the beverage cold, beverage vessels have been provided with a surrounding space filled with a “refrigerant gel”. The vessel is kept in a refrigerator or freezer to chill the gel prior to use. When a cooled beverage is poured into the vessel, the gel acts to absorb heat from the beverage to maintain its cold condition over an extended period of time.
- U.S. Pat. No. 5,001,907 describes such a vessel comprising a mug having a large handle which keeps the fingers from contacting the cold walls of the vessel, and insuring a secure grip.
- Heretofore, this “stay cool” design has not been employed in drinking vessels other than mugs due to the unpleasantness associated with directly grasping the outer wall of a drinking vessel which is chilled by such refrigerant gel. Also, body heat conducted through the fingers when the vessel walls directly grip the vessel would tend to warm the beverage. The outer wall would also be slippery and hard to handle securely when the grasped surfaces are chilled.
- It is the object of the present invention to provide a drinking vessel which has a “stay cool” outer wall which may be directly and securely gripped by a user without discomfort despite its low temperature condition, and which minimizes warming of the liquid by body heat.
- This object and others which will become apparent upon a reading of the following specification and claims are achieved by providing a series of widely spaced ribs projecting radially from the exterior perimeter wall defining a cavity containing the refrigerant gel. The ribs eliminates the discomfort otherwise experienced when the gel is chilled to keep the vessel's contents cool, and also reduces the transfer of heat from the holder's hand into the vessel.
- In addition, the ribs enable a more secure gripping of the vessel.
- The vessel is preferably constructed by nesting an inner transparent plastic beverage container piece into a plastic outer holder piece formed with the exterior ribs, and fixing the same together as by ultrasonic welding. The exterior of the beverage container piece and the interior of the holder piece are offset to define an annular cavity receiving the refrigerant gel.
- FIG. 1 is a perspective view of a stay cool drinking vessel according to the invention.
- FIG. 2 is a sectional view of the drinking vessel shown in FIG. 1.
- FIG. 3 is a top view of the drinking vessel shown in FIGS. 1 and 2.
- FIG. 4 is a bottom view of the drinking vessel shown in FIGS.1-3.
- FIG. 5 is a perspective view of a tall tumbler form of the drinking vessel according to the invention.
- FIG. 6 is a perspective view of a stemware form of the drinking vessel according to the invention.
- In the following detailed description, certain specific terminology will be employed for the sake of clarity and a particular embodiment described in accordance with the requirements of 35 USC 112, but it is to be understood that the same is not intended to be limiting and should not be so construed inasmuch as the invention is capable of taking many forms and variations within the scope of the appended claims.
- Referring to the drawings, in particular FIGS.1-4, a
drinking vessel 10 according to the invention is shown, taking the form of a generally medium sized cylindrical tumbler. - The exterior midsection is formed with a series of relatively widely spaced
ribs 12 projecting radially outwardly and extending vertically in an up and down direction. Theribs 12 are preferably thin, i.e., 0.25 cm thick and widely spaced, i.e., 26 rib spaced at 14° intervals around an approximately 8.5 cm diameter tumbler so as to minimize the area of contact with the fingers of a person holding the vessel. The spaces between theribs 12 is much wider than the thickness of theribs 12, so that the area of contact with the finger is much less than it would otherwise be. Theribs 12 are radiused at the top and taper down their length as best seen in FIG. 2, for aesthetic purposes and to improve the ease of gripping the tumbler. - The
drinking vessel 10 shown is of two piece construction, including an innerbeverage container piece 14, and anouter holder piece 16, thecontainer piece 14 nested into theholder piece 16, with the upper end of thecontainer piece 16 projecting above the holder piece to be exposed for a distance of several centimeters of its height. This makes it easier to observe the contents, as thecontainer piece 14 is preferably of transparent plastic. - The
container piece 14 has step orshoulder 18 to create an offset to form an annular axially extending space between theexterior 20 of thecontainer 14 and theinside 22 of theholder piece 16. Theholder piece 16 has anupper rim 26 received in agroove 28 in theshoulder 18 of thecontainer piece 14 located to suspend thecontainer piece 14 above thebottom 30 of theholder piece 16. The cavity defined therebetween extends across the bottom thevessel 10. - A volume of a refrigerant gel32 is loaded into the cavity as through a
hole 34 in the bottom wall of theholder piece 16 and sealed to permanently be filled with the gel. Suitable such refrigerant gels are well known, as described in U.S. Pat. No. 5,001,907 and other patents referenced. - The relatively thin and widely spaced
ribs 12 minimize the area of contact with the fingers of a person gripping thevessel 10. This minimizes the heating of thecontainer piece 14 by the conduction of heat into from the fingers, and also minimizes the sensation of cold experienced in the fingers of the person gripping the same. At the same time, the grip is made more secure by the presence of theribs 12. - The
beverage vessel 10 is first chilled as by being placed in a refrigerator or freezer. The gel has a high heat capacity such as to absorb heat from the surroundings and only very slowly rise in temperature, tending to substantially slow the warming of a cold beverage poured into thecontainer piece 14. - The
outer holder piece 16 andcontainer piece 14 may be molded from a suitable plastic, thecontainer piece 14 preferably transparent as noted above and theholder piece 16 desirably of a colored translucent or opaque plastic. - FIG. 5 shows a
tall tumbler 10A as an alternate embodiment of a invention, 9 while FIG. 6 shows astemware drinking vessel 10B as yet another embodiment.
