Abstract
A thermally-regulated bottle has a generally cylindrical body portion defining a first chamber for containing a drinking fluid and defining a central longitudinal axis. A passage is provided for accessing the drinking fluid. A secondary thermal-regulating container contains a thermal-regulating material, such as ice water, or heated water. According to a first embodiment of the invention, the bottle includes a recess which is positioned generally parallel to and remote from the central longitudinal axis, along the side of the bottle. The recess being sized and shaped to selectively receive the secondary thermal-regulating container so that the thermal-regulating material may thermally interact with the drinking fluid located within the chamber and either keep the drinking fluid heated or chilled with respect to the ambient temperature for a prolonged period of time. According to a second embodiment of the invention, the bottle includes a centrally located chamber which is sized and shaped to snugly receive the secondary container from an access opening located at the bottom of the bottle. Regardless of the arrangement, the heated or chilled material of the secondary container thermally reacts with the drinking fluid of the bottle and maintains either a chilled or heated temperature, as desired.
Description
- This is a continuation of application Ser. No. 09/650,099, filed Aug. 25, 2000. Each of these prior applications is hereby incorporated herein by reference, in its entirety.
- a) Field of the Invention
- This invention relates generally to the field of drinking vessels, and more particularly to specialized vessels used to contain a drinking fluid and which include an isolated thermal regulating element to help maintain a desired temperature of the drinking fluid.
- b) Description of Prior Art
- Generally, all beverages today are packaged in either cardboard cartons, plastic or glass bottles, or metal cans (e.g., steel or aluminum), in amounts that are suitable for an individual to consume. Typically, the consumer will chill the beverage in a refrigerator prior to consuming it. If the consumer removes a chilled beverage from refrigeration, the beverage will immediately begin to absorb heat from the surrounding environment until eventually the beverage becomes thermally equilibrated with the ambient temperature. Of course, if the ambient temperature is colder than then the operating temperature of the refrigerator, the removed beverage will loose more heat to the colder surrounding environment, again until thermal equilibrium is reached.
- Thermal equilibration between the beverage and the ambient temperature will be reached in a period of time depending on several factors, including the initial chilled temperature of the beverage, the temperature of the surrounding environment (i.e., ambient), the particulars of the environment (e.g., direct sunlight, humidity, and/or wind), and the type of material used to contain the beverage (e.g., a cardboard container may resist heat transfer better than an aluminum can), and the presence of local heat generating (e.g., electric heater), or heat absorbing (e.g., ice) elements.
- Of course, it is possible to slow down the process of thermal transfer from the surrounding environment to the beverage by placing the beverage in a cooler filled with ice, or surrounding the beverage container with an insulative jacket, such as a “koolie” which is usually made from a foam-rubber material. Although such devices are generally useful at prolonging a chilled (or heated) temperature of a beverage, these devices are generally cumbersome to carry and difficult to use.
- It is therefore an object of the present invention to provide an improved drinking bottle having a thermal regulating element, which overcomes the deficiencies of the prior art.
- It is therefore an object of the present invention to provide a thermally efficient container that prolongs a desired temperature (chilled or heated) of a beverage.
- It is another object of the invention to provide such a container that is easy to use and portable to transport.
- A thermally-regulated bottle has a generally cylindrical body portion defining a first chamber for containing a drinking fluid and defining a central longitudinal axis. A passage is provided for accessing the drinking fluid. A secondary thermal-regulating container contains a thermal-regulating material, such as ice water, or heated water.
- According to a first embodiment of the invention, the bottle includes a recess which is positioned generally parallel to and remote from the central longitudinal axis, along the side of the bottle. The recess being sized and shaped to selectively receive the secondary thermal-regulating container so that the thermal-regulating material may thermally interact with the drinking fluid located within the chamber and either keep the drinking fluid heated or chilled with respect to the ambient temperature for a prolonged period of time.
- According to a second embodiment of the invention, the bottle includes a centrally located chamber which is sized and shaped to snugly receive the secondary container from an access opening located at the bottom of the bottle.
- Regardless of the arrangement, the heated or chilled material of the secondary container thermally reacts with the drinking fluid of the bottle and maintains either a chilled or heated temperature, as desired.
- There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
- In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description of illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
- As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other similar structures, methods and systems for carrying out the several proposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions in so as they do not depart from the spirit and scope of the present invention.

- Referring to FIGS.1-5, a first embodiment of the invention is shown, including a
drinking bottle 10, and a secondary temperature-regulatingcontainer 12. Bottle 10 is preferably made from a suitable plastic, such as polyethylene terephthalate (PET) and includes an off-center side-accessible recess 14 having an arcuate insidewall surface 15 and defining anaccess opening 17. Insidewall surface 15 is generally sized and shaped to selectively receive and snugly holdsecondary container 12. Recess 14 preferably has a cross-sectional shape which is similar to the cross-sectional shape ofsecondary container 12 so that whensecondary container 12 is located withinrecess 14, the walls ofsecondary container 12 snugly contact the inside walls ofrecess 14.Recess 14 is generally located along the side ofbottle 10, parallel to and remote from the longitudinal central axis ofbottle 10, as shown in FIGS. 2 and 4. -
Secondary container 12 may be any appropriate size and shape, however, it is preferred thatsecondary container 12 be generally cylindrical and no larger than about {fraction (1/3)} the size of thebottle 10. The purpose ofsecondary container 12 is to contain a liquid (or other material) which may be heated or chilled and to thermally maintain a drinking liquid ofbottle 10 at a desired temperature for a prolonged period of time. For example,secondary container 12 may contain a liquid that is suitable for freezing, such as water. Once chilled,secondary container 12 is inserted intorecess 14, as described below, so that any drinking liquid inbottle 10 may thermally transfer its heat to the chilledsecondary container 12, and become chilled, to an equilibrated temperature, similar to putting ice directly into a drink. -
Bottle 10 andcontainer 12 may be made from any suitable material using an appropriate manufacturing process, as is generally known by those skilled in the art. Some commonly used manufacturing processes for making similar containers include injection molding and blow-type molding. Other materials suitable for eitherbottle 10 orsecondary container 12 include other flexible or semi-rigid plastics, glass, and metal. - As shown in FIGS. 2, 4, and5,
bottle 10 further includes a cuppedbase 18 located at a lower end 20 ofbottle 10.Base 18 is also made from a plastic and includes a relativelyflat bottom 22 and a generallycylindrical side wall 24.Side wall 24 is sized and shaped to snugly receive lower end 20 ofbottle 10, as shown in FIGS. 2, 4, and 5.Base 18 is preferably adhered or otherwise attached to lower end 20 ofbottle 10 so that a portion ofside wall 24 covers a lower end portion of access opening 17 ofrecess 14. The purpose ofbase 18 is to protect lower end 20 ofbottle 10, and also help retainsecondary container 12 withinrecess 14 ofbottle 10. - Referring to FIG. 5, and in accordance with this embodiment of the invention,
secondary container 12 is inserted intorecess 14 by first positioning alower end 26 ofsecondary container 12 through access opening 17 ofrecess 14 so thatlower end 26 ofsecondary container 12 lies adjacent tobottom 22 ofbase 18, as illustrated byarrow 28 of FIG. 5. Afterlower end 26 ofsecondary container 12 is snugly positioned as shown in FIG. 5, anupper end 30 ofsecondary container 12 may be pushed through access opening 17 (as illustrated by arrow 29) untilsecondary container 12 is located entirely withinrecess 14, snugly contactingside walls 15 ofrecess 14, and lying generally parallel to the longitudinal axis ofbottle 10. The ends 16 ofside walls 15 ofrecess 14 preferably define anaccess opening 17 having a width that is slightly smaller than the width ofsecondary container 12 so that the ends 16 ofside walls 15 and/orsecondary container 12 must temporarily flex and distort during insertion ofsecondary container 12 intorecess 14. Oncesecondary container 12 is fully inserted intorecess 14,secondary container 12 is held withinrecess 14 by friction, and bybase 18. - Referring to FIGS. 6, 7,8, 9, 10, and 11, another embodiment of the invention is shown including a
bottle 50, having a central, axially locatedchamber 52 which is sized and shaped to snugly receive asecondary container 54, not from the side as in the above-described embodiment, but from an access opening 56 located at alower face 58 ofbottle 50.Secondary container 54 preferably includes acap 60 which may be selectively opened to allow the filling ofsecondary container 54 with an appropriate liquid. -

closure 66 includes an appropriate seal, such as a circumferentially located O-ring which effectively sealschamber 52 upon engagement with threading 62, 64. In this manner, a chilled or heated liquid may be introduced directly intochamber 52, without requiringsecondary container 54. - Referring to FIGS. 12, 13,14, and 15, another embodiment of the invention is shown including a
bottle 100, having arecess 102 which is positioned along the side wall ofbottle 100 and is sized and shaped to snugly receive asecondary container 104. This embodiment is essentially identical to the embodiment of FIGS. 1-5, described above, except that nobase 18 is used. Instead,secondary container 104 is inserted withinrecess 102 through a lower access opening 106, shown in FIGS. 15 and 16. Once inserted,secondary container 104 is retained withinrecess 102 through the resilient friction imparted by thewalls 115 ofbottle 100 adjacent to recess 102. In this embodiment, the diameter ofrecess 102 is preferably slightly smaller than the outer diameter ofsecondary container 104 ensuring that sufficient friction will exist to holdsecondary container 104 withinrecess 102. To removesecondary container 104 fromrecess 102,secondary container 104 is pushed downwardly from the top and removed from the lower access opening 106. - While the invention has been described and illustrated with reference to certain preferred embodiments thereof, those skilled in the art will appreciate that various changes, modifications and substitutions can be made therein without departing from the spirit and scope of the invention. For example, the secondary container in any of the above embodiments does not have to be a thermally regulating container. The secondary container may be, for example, a container of bottled water or even non-potable fluid, where the bottle, for example, is a bottle of soda so that the seller can include a sample of one product while selling another. It is intended, therefore, that the invention be limited only by the scope of the claims which follow and that such claims be interpreted as broadly as is reasonable.
