Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

Referring to fig. 1-3, a thermal cup includes a first cup 110, a first sleeve 120, a first seal 130a, a second seal 130b, a third seal 130c, a fourth seal 130d, and a first lid 140. The first cup 110 includes a first outer sleeve 111 and a first inner container 113. The first outer sleeve 111 has a first port 111a and an accommodating space a. First port 111a is opposite base 1111 of first outer sleeve 111. The accommodating space a is formed between the first port 111a and the base 1111. The first inner container 113 passes through the first port 111a and is accommodated in the accommodating space a. The third seal ring 130c abuts between the base 1111 of the first outer sleeve 111 and the bottom plate 1131 of the first inner container 113. The third seal ring 130c has elasticity. Thus, the third sealing ring 130c can absorb the impact of the vacuum cup in a specific direction to prevent the first inner container 113 from being broken.

The first sleeve 120 is sleeved on the first outer wall 113a of the first inner container 113 and coupled to the first outer sleeve 111 in the accommodating space a. Specifically, the first kit 120 includes a first engagement portion 122. The first engaging portion 122 is disposed on the second outer wall 120a of the first sleeve 120. The first engagement portion 122 is an external thread. The first outer sleeve 111 includes a second engagement portion 1113. The second engagement portion 1113 is disposed on the first inner wall 111b of the first outer sleeve 111. The second engagement portion 1113 is an internal thread. The first sleeve 120 is coupled to the first outer sleeve 111 by screwing the first engagement portion 122 and the second engagement portion 1113. Thus, the first inner container 113 can be fixed in the first outer sleeve 111 by screwing the first sleeve 120 and the first outer sleeve 111.

The first sealing ring 130a is sleeved on the second outer wall 120a of the first sleeve 120 and abuts between the first sleeve 120 and the first outer sleeve 111. The second sealing ring 130b is sleeved on the first outer wall 113a of the first inner container 113 and abuts between the first inner container 113 and the first outer sleeve 111. Further, the first inner container 113 includes a boss 1133. The boss 1133 is connected to the first outer wall 113a of the first inner container 113 and protrudes relative to the first outer wall 113a of the first inner container 113. The second seal ring 130b is disposed on the boss 1133. The first sleeve 120 is further provided on the second seal ring 130 b. In other words, in one direction, the second seal ring 130b is in contact with the space between the first sleeve 120 and the boss 1133, and in the other direction, the second seal ring 130b is in contact with the space between the first inner container 113 and the first outer sleeve 111.

In the manufacturing process of the first inner container 113, the first outer sleeve 111 and the first kit 120, due to tolerance, the outer edges of the first inner container 113, the first outer sleeve 111 and the first kit 120 may not be completely matched during assembly, so that a gap exists between the first outer sleeve 111, the first inner container 113 and the first kit 120. The first and second sealing rings 130a and 130b are disposed between the first outer sleeve 111, the first inner container 113, and the first kit 120 to fill the gaps therebetween, thereby preventing liquid such as beverage or water from flowing into the gaps between the first outer sleeve 111, the first inner container 113, and the first kit 120. In addition, the first sealing ring 130a and the second sealing ring 130b can also increase the friction force between the first inner container 113, the first outer sleeve 111 and the first sleeve 120, thereby preventing the first inner container 113, the first outer sleeve 111 and the first sleeve 120 from sliding or rotating relatively to each other and loosening, if liquid inadvertently flows between the first inner container 113 and the first sleeve 120 or between the first outer sleeve 111 and the first sleeve 120, the boss 1133 can block the liquid, so that the liquid is accumulated on the boss 1133, and the user can pour the vacuum cup, and the liquid can flow out quickly.

The second top surface 120b of the first sleeve 120 is flush with the first top surface 111c of the first outer sleeve 111. The first liner 113 has a cup mouth 113 c. The cup opening 113c extends and protrudes relative to the second top surface 120b of the first sleeve member 120 and the first top surface 111c of the first outer sleeve 111. In other words, the cup opening 113c is partially exposed via the first port 111a of the first outer sleeve 111. The first cup cover 140 is detachably connected with the cup opening 113c of the first inner container 113, when the mouth of a user is close to the cup opening 113c to drink liquid in the first inner container 113, the mouth of the user directly contacts with the first inner container 113, the first sleeve 120 cannot be touched, the sanitation is good, and the appearance is more attractive.

The first outer wall 113a at the cup opening 113c is provided with a first external thread 1135. The second inner wall 140a of the first cap 140 includes internal threads 142. The first lid 140 is screwed with the first external thread 1135 of the first inner container 113 through the internal thread 142 to close the cup opening 113 c. The cup mouth 113c has a first annular inclined surface 113c 1. The first annular inclined surface 113c1 is disposed on an inner wall of the first inner container 113. The width of the first annular inclined surface 113c1 increases in the vertical direction near the first cap 140. The first cap 140 includes a ledge 144. The projection 144 projects toward the cup mouth 113 c. When the first cap 140 is screwed with the first inner container 113, the protrusion 144 is partially received in the cup opening 113 c. The projection 144 has a second annular slope 1441. A second annular slope 1441 is provided to an outer wall of the protruding portion 144. The width of the second annular inclined surface 1441 is tapered in the vertical direction near the cup mouth 113 c. In other words, the changing direction of the width of the first annular slope 113c1 is substantially the same as the changing direction of the width of the second annular slope 1441.

The fourth seal ring 130d is disposed on the protrusion 144. When the first cap 140 is screwed to the first inner container 113, the fourth sealing ring 130d abuts between the first annular inclined surface 113c1 and the second annular inclined surface 1441. By the width-variable combination of the first annular inclined surface 113c1 and the second annular inclined surface 1441, the fourth sealing ring 130d can effectively plug the gap between the first cup cover 140 and the first inner container 113, and prevent the liquid contained in the first inner container 113 from leaking out.

The first, second, third and fourth seal rings 130a, 130b, 130c and 130d may be omitted, or one or more of the first, second, third and fourth seal rings 130a, 130b, 130c and 130d may be provided.

When assembling the vacuum cup, the second sealing ring 130b and the first sleeve 120 are sequentially sleeved on the first outer wall 113a of the first inner container 113. Then, the first sealing ring 130a is sleeved on the second outer wall 120a of the first sleeve 120. Finally, the first sleeve 120 is screwed and fixed with the first outer sleeve 111, and the assembly of the vacuum cup is completed. The assembly mode omits the use of adhesive, can greatly shorten the assembly time of the vacuum cup, and does not have the problem that the first inner container 113 falls out of the first outer sleeve 111 due to aging of the adhesive. In addition, the first outer sleeve 111 with high mechanical strength is wrapped outside the first sleeve 120 with low mechanical strength, so that the first sleeve 120 can be protected, and the first sleeve 120 and the first inner container 113 are prevented from being cracked when the vacuum cup falls off. When in maintenance, only the first liner 113 needs to be replaced, and the first sleeve member 120 can be repeatedly used, thereby reducing the maintenance cost.
