Name of Applicant: Actual Inventor: Agent and Address for Service: Invention Title: Spero Pavlos Spero Pavlos MADDERNS, 1st Floor, 64 Hindmarsh Square, Adelaide, South Australia, Australia CUP ASSEMBLY HAVING A COOLING
COMPARTMENT
The following statement is a full description of this invention, including the best method of performing it known to me.
la 0 CUP ASSEMBLY HAVING A COOLING COMPARTMENT 1. Field of the Utility Model c, The present utility model relates to a cup assembly, and more particularly to the cup assembly having a cooling compartment to cool a portion of hot liquid contained in the cup body.
2. Description of Related Art SWith reference to Fig. 13, U.S. Pat. No. 6,571,973 discloses a cup lid (40) which is composed of a lid seat (41) and a cover (42).
The lid seat (41) has an inclined bottom plate (414) relative to the cover a first recess (411) defined in the bottom plate (414) to be mounted on a top periphery of a cup (50) and a second recess (416) defined in the bottom plate (414) to be mounted on the top periphery of the cup It is noted that the first recess (411) has a height greater than that of the second recess (416) such that after the lid seat (41) is mounted on top of the cup the bottom plate (414) is slanted. The cover (42) is able to be sealingly mounted on top of the lid seat (41) to define a liquid receiving space between the cover (42) and the bottom plate (414) of the lid seat (41).
Due to the first recess (411) defined in the bottom plate (414), the liquid receiving space is divided into a first chamber (412) and a second chamber (413). The bottom plate (414) further has an inlet (415) defined to communicate with an interior of the cup (50) and the first chamber (412). The cover (42) further has an outlet (421) defined through the cover (42) to communicate with the first chamber (412).
With reference to Figs 14, 15 and 16, when the conventional cup assembly is in use, the user is able to tilt the cup assembly to allow liquid contained in the cup (50) to flow into the first chamber (412) and the second chamber (413) from the inlet (415).
2 Then the cup assembly is placed upright again to allow a portion of the liquid flowing
O
into the first chamber (412) to flow back to the cup (50) and a portion of the liquid flowing into the second chamber (413) to be kept in the second chamber (413). Because a portion of the liquid flows into the second chamber (413), the area of the second chamber (413) facilitates a heat dissipation effect to the liquid in the second chamber (413). Thus the temperature of the liquid in the second chamber (413) reduces faster O than that of the liquid still contained in the cup Therefore, the user is able to use the outlet to sip the temperature-reduced liquid via the outlet (421) of the cover (42).
Although the conventional cup assembly does provide protection to the user to prevent mouth injury from the hot liquid in the cup the user will have to adopt this two-phase process to drink the liquid even after the liquid temperature in the cup has dropped to drinkable level, which is very inconvenient to the user.
To overcome the shortcomings, the present utility model tends to provide an improved cup assembly to mitigate the aforementioned problems.
The primary objective of the present utility model is to provide an improved cup assembly to provide two passages in the lid and the cup to allow the user to selectively choose one of the passages to communicate with a liquid cooling chamber so as to perform different functions.
Another objective of the present utility model is to provide a positioning device to limit a rotation angle of the lid relative to the cup.
Other objects, advantages and novel features of the utility model will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
In the drawings: 3 Fig. 1 is an exploded perspective view of the cup assembly of the present utility 0 model; Fig. 1A is a schematic perspective view partially cross sectioned to show the corresponding relationship among the first cutout, the second cutout, the third cutout and the fourth cutout of the cup assembly; Figs 2, 3 and 4 are schematic views showing the application of the cup assembly of the present utility model; Fig. 5 is a schematic view showing the application of the cup assembly to allow the user to drink the cooled liquid in the liquid cooling chamber; Fig. 6 is an exploded perspective view showing the second embodiment of the present utility model, wherein there is provided one passage instead of two passages between the lid and the cup; Fig. 6A is a schematic perspective view partially cross sectioned to show the corresponding relationship among the first cutout, the third cutout and the fourth cutout of the cup assembly; Figs 7 to 10 are schematic views showing the application of the second embodiment of the present utility model; Fig. 11 is a perspective view showing the addition of a rotation restriction device to limit rotation of the lid relative to the cup; Fig. 12 is a perspective view showing the application of the rotation restriction device; Fig. 13 is a cross sectional view showing the structure of a conventional cup assembly; and Figs 14 to 16 are schematic cross sectional views showing the application of the 4 Sconventional cup assembly.
0 0 With reference to Fig. 1, the cup assembly in accordancewith the present utility model includes a cup (10) and a lid (20) which is able to be mounted on top of the cup to cover the open end of the cup The cup (10) is provided with an inner wall (12) in connection with a peripheral edge of the cup (10) to define therebetween a first chamber a first cutout (13) and a second cutout both the first cutout (13) and the second cutout (14) being defined in the inner wall Furthermore, a longitudinal slit (17) is defined in an outer circumference of the inner wall (12) and a latitudinal slit (16) is also defined in the outer circumference of the inner wall (12) to intersect with the longitudinal slit (17).
The lid (20) includes an inner extension (21) extending from a bottom face of the lid (20) to define a second chamber (22) with an outer wall (26) which is extended from an outer periphery of the lid an outlet (23) is defined through the lid (20) to communicate with the second chamber a third cutout (24) defined in the inner extension (22) to correspond to and align with the first cutout and a fourth cutout defined in the inner extension (22) to correspond to and align with the second, cutout Furthermore, the lid (20) has a limiting element such as a ball or the like, mounted on the inner extension (22) to correspond to the longitudinal slit (17) and the latitudinal slit (16).
With reference to Fig. 1A, it is noted that when the lid (20) is mounted on top of the cup (20) to cover the open end of the cup the third cutout (24) is able to selectively communicate with the first cutout (13) and the fourth cutout (25) is able to selectively communicate with the second cutout wherein from the depiction in Fig.
1A, the first cutout (13) is aligned with the third cutout (24) and the second cutout (14) is not aligned with the fourth cutout That is, when the third cutout (24) is O communicated with the first cutout (13) to define a first passage, the communication between the fourth cutout (25) and the second cutout which forms a second passage, is blocked by the inner extension (22) and the inner wall (12) and vice versa.
With reference to Figs 2, 3, 4 and 5, when the cup assembly of the present utility model is in application, the user is able to rotate the lid (20) to communicate the fourth cutout (25) with the second cutout which in turn closes the communication between the first cutout (13) and the third cutout Then the user is able to tilt the cup assembly to allow a portion of the liquid inside the cup (10) to flow into a cooling compartment composed of the first chamber (11) and the second chamber after which the cup assembly is tilted again to hold the cup assembly upright again. Due to the increased area in the cooling compartment when compared with the area inside the cup the liquid temperature in the cooling compartment drops faster than that in the cup Thereafter, the user is able to rotate the lid (20) to align the first cutout (13) with the third cutout as shown in Fig. 4, to enable to user to drink the liquid in the cooling compartment from the outlet (23).
Further, when the lid (20) is mounted on the cup the limiting element (29) is first received in the longitudinal slit (17) to guide the mounting of the lid (20) in relation to the cup After the limiting element (29) is reached to a bottom of the longitudinal slit the limiting element (29) is able to move inside the latitudinal slit (16) when the lid (20) is rotated relative to the cup As a result of the provision of the latitudinal slit the rotation of the lid (20) in relation to the cup (10) is limited.
With reference to Fig. 6 and Fig. 6A, the second preferred embodiment of the present utility model includes a cup (10) and a lid wherein the structure of the 6 Ssecond embodiment is substantially the same as that of the first embodiment. As
O
consequence of the similarity, the same elements in this embodiment will be designated with the same reference numeral as those used in the first embodiment. The difference therebetween lies in that the inner wall (12) has one cutout, i.e. the first cutout to align with the third cutout (24) to form a first passage and the second cutout of the cup is removed from this embodiment. The fourth cutout (25) has a particular depth so that after the lid (20) is mounted on top of the cup a portion of the fourth cutout is exposed out of the inner wall (12) to become a second passage.
With reference to Figs 7, 8, 9 and 10, after the lid (20) is mounted on top of the cup (10) to close the open end of the cup the user is able to rotate the lid (20) to misalign the first cutout (13) and the third cutout (24) so as to block the communication between the first passage with the outlet Meanwhile, because the fourth cutout has a depth exceeding the height of the inner wall (12) of the cup the user is able to tilt the cup assembly to allow the hot liquid contained in the cup (10) to flow into a cooling compartment composed of the first chamber (11) and the second chamber (22), after which the cup assembly is tilted again to hold the cup assembly upright again. Due to the increased area in the cooling compartment when compared with the area inside the cup the liquid's temperature in the cooling compartment drops faster than that in the cup Thereafter, the user is able to rotate the lid (20) to align the first cutout (13) with the third cutout as shown in Figs 9 and 10, to enable to user to drink the liquid in the cooling compartment from the outlet (23).
With reference to Figs 11, 11A and 12, the cup assembly of the present utility model further has a rotation facilitating device to facilitate and limit the rotation of the lid (20) relative to the cup 7 SThe rotation facilitating device includes a recess (261) defined in a peripheral O edge of the outer wall (26) of the lid multiple teeth (27) formed on a bottom face c' defining the recess (261), a gear (31) rotatably mounted on an outer periphery of the cup a rack (32) slidably and movably received in a seat (18) which is rigidly mounted on the outer periphery of the cup (10) to support the rack (32) therein such that the rack (32) is able to mate with the teeth (27) of the lid (20) and a tab (33) formed on a distal end of the rack (32).
When the rotation facilitating device is used, the user is able to push or pull the tab (33) to drive the rack (32) to move relative to the seat Due to the movement of the rack (32) and the alignment between the rack (32) and the teeth (27) on the lid the lid (20) is driven to rotate so as to adjust the alignment of the cutouts (24,25) of the lid (20) with the cutouts (13,14) of the cup (10) (in the first embodiment) and thus the user is able to easily accomplish the adjustment to the communication or blockage of the first passage and the second passage. Furthermore, due to the length of the recess (261), the rotation of the lid (20) is limited so that the gear (31) is able to selectively engage with one of two distal ends of the recess (261) in the outer wall (26) of the lid As a result, the rack (32) is prevented from falling off the seat (18).
It is to be understood, however, that even though numerous characteristics and advantages of the present utility model have been set forth in the foregoing description, together with details of the structure and function of the utility model, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the utility model to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
