TEMPERATURE KEEPING CONTAINER
A temperature keeping container includes an inner receptacle and an outer vessel. The inner receptacle is fit in the outer vessel in a tight manner to form an accommodation chamber between the inner receptacle and the outer vessel for receiving and containing a low- or high-temperature medium as desired, or a substance, preferably an edible substance, that is frozen to form a freezing layer, whereby beverage, when deposited in the inner receptacle of the container, can be kept cool to allow a user to enjoy cold beverage of the original flavor, or alternatively, beverage can be poured onto the freezing layer to mix with the substance forming the freezing layer to provide a mixed flavor of beverage.
The present invention generally relates to a container, and more particularly to a container that is composed of an inner receptacle and an outer vessel that define therebetween an accommodation chamber that receives therein a low- or high-temperature medium or a substance that is frozen to form a freezing layer so as to allow a user to change the way of enjoying beverage as desired.
(b) DESCRIPTION OF THE PRIOR ARTTemperature keeping containers are known, such as Taiwan Patent Publication No. 369875, which discloses an improved structure of cold-keeping container. The cold-keeping container comprises an inner receptacle, a suction member, and an outer vessel. The inner receptacle is inserted in the outer vessel to form a space therebetween for receiving and containing a cold-keeping medium. The inner receptacle has a bottom to which the suction member is attached. The suction member extends through the space formed between the inner receptacle and the outer vessel to project outside the container. As such, when a user sucks beverage through the suction member, the beverage gets contact with the cold-keeping medium through the suction member so as to keep the beverage cool or to fast cool down the beverage.
However, the conventional cold-keeping container, although effective in keeping cold or fast cooling an object, the cold keeping medium used in the container is a liquid chemical freezing agent, which provides a single function of temperature isolation and cooling of beverage, and does not allow the beverage contained in the container to directly contact a frozen layer formed by freezing the cold keeping medium. Functionally, since the container is pre-loaded with the cold keeping medium, the container only serves for cold keeping or fast cooling of an object and does not offer other uses. Further, to prevent leaking of the liquid chemical agent of cold keeping medium, a selected material must be used, together with properly designed molds, for manufacturing of the container. Thus, the conventional cold-keeping container is uneconomic and impractical in view of the manufacturing costs and structure thereof.
SUMMARY OF THE INVENTIONThe present invention aims to provide a temperature keeping container that has a simple structure and is easy to use, but allows a user to switch among different ways of enjoying beverage as desired.
According to the present invention, a temperature keeping container comprises an inner receptacle and an outer vessel. The inner receptacle is fit in the outer vessel in a tight manner to form an accommodation chamber between the inner receptacle and the outer vessel for receiving and containing a low- or high-temperature medium as desired, or a substance, preferably an edible substance, that is frozen to form a freezing layer, whereby beverage, when deposited in the inner receptacle of the container, can be kept cool to allow a user to enjoy cold beverage of the original flavor, or alternatively, beverage can be poured onto the freezing layer to mix with the substance forming the freezing layer to provide a mixed flavor of beverage.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

The present invention provides a container that comprises an inner receptacle 2 that is received inside an outer vessel 3 in a tight manner to define an accommodation chamber therebetween for receiving and holding therein a low- or high-temperature medium 4 or alternatively receiving a medium that is subjected to freezing to form a freezing layer 4′. A beverage 5 can be poured into the inner receptacle 2 to allow a user to enjoy a cool beverage 5 of the original flavor, or the inner receptacle 2 is removed and the beverage 5 is poured into the freezing layer 4′ to allow the user to enjoy the beverage 5 that is mixed with the substance of the freezing layer 4′. Further, the accommodation chamber can receive and contain warm or hot water to provide heating and/or heat preservation for the beverage 5 deposited in the inner receptacle 2. Further, the shapes of the inner receptacle 2 and the outer vessel 3 can be varied according to the uses thereof, such as being made in the form of a kettle, a beer mug, or even a temperature keeping barrel, a dish, a bowl, a disk, or a cup.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Claims
1. A temperature keeping container, comprising an inner receptacle and an outer vessel, which are fit to each other to define an accommodation chamber therebetween that receives and contains therein a low- or high-temperature medium, the inner receptacle being removable from the outer vessel.
2. The temperature keeping container according to claim 1, wherein the medium that is received in the accommodation chamber between the inner receptacle and the outer vessel is freezable to form a freezing layer, whereby a beverage is selectively poured into the inner receptacle or directly onto the freezing layer.
3. The temperature keeping container according to claim 1, wherein the inner receptacle has a top end section that is slightly diverging and forms a flange that defines a fitting rim with respect to the inner receptacle and wherein the outer vessel defines an inner bore having an inner circumferential edge that is formed to correspond to the fitting rim so as to allow the fitting rim of the inner receptacle to be fit into the inner circumferential edge of the bore of the outer vessel for coupling the inner receptacle and the outer vessel together in a tight manner.
4. The temperature keeping container according to claim 1, wherein the inner receptacle and the outer vessel form threads that engage each other to detachably couple the inner receptacle and the outer vessel together.
5. The temperature keeping container according to claim 1, wherein the inner receptacle and the outer vessel are integrally formed together to define the accommodation chamber therebetween and wherein the outer vessel has an open bottom in which a thread is formed for selective threading engagement with an inner cup to close the open bottom.
