1. Fields of the Invention
The present invention relates to a dual-cup assembly, and more particularly, to a dual-cup assembly that is easily assembled and has an inner cup and an outer cup.
2. Descriptions of Related Art
The conventional dual-cup assembly generally is composed of an inner cup and an outer cup in which the inner cup is received, and a space is defined between the inner and outer cups. The space is made to be a vacuum space so as to isolate air from being in contact with the inner cup so that the temperature of the liquid in the inner cup can be maintained for a longer period of time. The vacuum space does not have air received therein and the heat of the liquid is then kept in the inner cup.
A conventional dual-cup assembly is disclosed in Taiwan Utility Model M339276 and has a jar with an opening. A first connection portion is formed at the opening. The jar has an outer portion and an inner portion, and a space is formed between the inner and outer portions. A cap has a second connection portion to be connected with the first connection portion to seal the opening.
The space is made to be a vacuum space, and the inner portion and the outer portion are connected to each other by a special method. These requirements make the dual-cup assembly be expensive. Besides, the inner portion cannot have replaceable patterns to provide visual characters.
The present invention intends to provide a dual-cup assembly to eliminate the shortcomings mentioned above.
The present invention relates to a dual-cup assembly and comprises an inner cup, an outer cup and a fastening unit. The inner cup has a space defined therein and a first flange extends from the outside of the inner cup. The outer cup has a reception room in which the inner cup is received. A second flange extends from the outside of the outer cup. The fastening unit is mounted to the first flange and the second flange to connect the inner cup and the outer cup together.
Preferably, a seal ring is located between the first and second flanges.
Preferably, the fastening unit comprises a first member, a second member and a restriction member. The second member is pivotably connected to the first member. Each of the first member and the second member has a groove defined in the inner periphery thereof. The first and second flanges are received in the two respective grooves. Each of the first and second members has a tongue extending from the distal end thereof. The restriction member has a passage in which the two tongues are inserted.
Preferably, the first and second members are formed integrally to each other.
Preferably, the first and second members are pivotably connected to each other by a connection member.
Preferably, the two respective grooves of the first and second members are C-shaped.
Preferably, the passage is defined in the top of the restriction member. The two tongues are inserted into the passage and the restriction member is used as a handle.
Preferably, the passage is defined in one of the sides of the restriction member. The two tongues are inserted into the passage and the restriction member is used as a handle.
The primary object of the present invention is to provide a dual-cup assembly which is easily manufactured and has satisfied sealing feature.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The fastening unit 3 comprises a C-shaped member 31 and a restriction member 32. The C-shaped member 31 has a groove 311 defined in the inner periphery thereof. The first and second flanges 12, 22 are received in the groove 311. Two tongues 312 respectively extend from two distal ends of the C-shaped member 31. The restriction member 32 has a passage 321 in which the two tongues 312 are inserted.
As shown in
As shown in
The passage 321 is defined in the top of the restriction member 32. When the two tongues 312 are inserted into the passage 321 of the restriction member 32 to secure the first and second members 31, 31, the restriction member 32 is used as a handle as shown in
Alternatively, the passage 321 is defined in one of sides of the restriction member 32. When the two tongues 312 are inserted into the passage 321 of the restriction member 32 to secure the first and second members 31, 31, the restriction member 32 is used as a handle as shown in
The dual-cup assembly is easily assembled by using the fastening unit 3 to secure the first and second flanges 12, 22 of the inner and outer cups 1, 2. By filling isolation material or colorful material in the room between the inner and outer cups 1, 2, the dual-cup assembly has more visual attractions and the temperature of the liquid in the inner cup is kept for a longer period of time.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
