Description

Technical Field

[0001] This utility model relates to the field of thermal insulation container technology, and in particular to a liquid thermal insulation container. Background Technology

[0002] A double-walled stainless steel thermos flask is available, comprising a spout and a double-walled stainless steel inner liner. The upper end of the inner liner is open, and a protrusion is integrally formed on the upper outer circumference of the inner liner below the opening. A handle is located on one side of the spout, and a mounting groove with a hook is provided inside the spout. The upper part of the inner liner is fitted into the mounting groove, and the hook engages upwards with the protrusion to secure the spout to the inner liner. During use, the user lifts the thermos flask by the handle. Since the handle is located on the spout, it does not provide support for the inner liner; the inner liner and spout are only connected by the hook and the protrusion. The convex and concave parts are connected together, so the connection between the convex hook and the convex part needs to bear the entire weight of the inner pot. However, since the convex part and the inner pot are molded as a single piece, due to the limitations of the molding process, the shape of the convex part has a relatively large curvature. This results in the convex part and the hook engaging with each other, leading to poor connection stability. As a result, during use, the hook can easily detach from the convex part, causing the inner pot to detach from the spout. This is especially true when the inner pot contains a solution, which increases the weight that the connection between the hook and the convex part needs to bear, increasing the risk to the user.

In this embodiment, the second connecting part 11 and the first connecting part 21 are sealed by welding. The fixing ring 4 is made of stainless steel and includes a hollow fixing part 41 and a first fastening part 42. The fixing part 41 passes through the second connecting part 21 and is welded to the outer shell 2. The first fastening part 42 is disposed on the fixing part 41. The spout 5 has a pouring spout 52 on one side, and an installation cavity 51 is provided inside the spout 5, located below the pouring spout 52. The upper part of the outer shell 2 is fitted into the installation cavity 51. The opening of the inner liner 1 communicates with the pouring spout 52. The inner wall of the installation cavity 51 has a second fastening part 53, which fastens to the first fastening part 42. The handle 6 is located on the side of the spout 5 opposite to the pouring spout 52. By forming the first fastening part 42 in the fixing ring 4, the first fastening part 42 is formed separately from the outer shell 2, thereby preventing the part where the first fastening part 42 and the second fastening part 53 meet from forming an arc surface. This prevents the second fastening part from sliding off the first fastening part 42 along the arc surface, thereby increasing the stability of the engagement between the first fastening part 42 and the second fastening part 53, so that the connection between the first fastening part 42 and the second fastening part 53 can withstand a relatively large weight, ensuring user safety.

[0045] In a preferred embodiment, the fixing part 41 and the second connecting part 21 of the liquid insulation container of the present invention are spaced apart. Specifically, the inner diameter of the fixing part 41 is larger than the outer diameter of the second connecting part 21, and a gap is formed between the inner side of the fixing part 41 and the outer side of the second connecting part 21 to prevent the second connecting part 21 from being easily loosened by external force from the fixing part 41 and affecting the sealing performance of the connection between the second connecting part 21 and the first connecting part 11.

[0046] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In a preferred embodiment, the outer shell 2 of the liquid insulation container of this utility model further includes a vertical portion 22 disposed below the second connecting portion 21. The vertical portion 22 is sleeved within the mounting cavity 51. The cross-section of the fixing ring 4 includes a first end 411, a second end 412, and a bent portion 42. The second end 412 is located below the first end 411. Both the first end 411 and the second end 412 are attached to the vertical portion 22 to form the fixing portion 41. The bent portion 42 forms the first fastening portion 42. The bent portion 42 includes a downward extension from the first end 411 and a direction away from the vertical portion 22. The first segment 421 extends from the end of the first segment 421 to the second end 412, and the second fastening part 53 is configured as a hook 53, which fastens upward to the second segment 422. The cross-section of the fixing ring 4 is configured to include a first end 411, a second end 412 and a bent part 42. The bent part 42 includes a first segment 421 extending downward from the first end 411 and toward a direction away from the vertical part 22 and a second segment 422 extending from the end of the first segment 421 to the second end 412, so that the fixing ring 41 can be formed by stamping process, and materials are saved to reduce production costs.

[0047] refer to Figure 1 , Figure 2 In a preferred embodiment, the second segment 422 of the liquid insulation container of the present invention is inclined upward from the first segment 421 toward the second end 412, so that the second segment 422 forms a barb shape, which increases the stability of the engagement between the hook 53 and the second segment 422 and reduces the risk of the hook 53 disengaging from the second segment 422; in other embodiments, the second segment 422 may also be horizontally arranged.

[0048] refer to Figures 7-10In another embodiment, the difference from the preferred embodiment lies in the structure of the fixing ring 41. Specifically, the outer shell 2 of the liquid insulation container of this utility model further includes a vertical portion 22 located below the second connecting portion 21. The vertical portion 22 is fitted inside the mounting cavity 51 and protrudes outward from the second connecting portion 21. The vertical portion 22 and the second connecting portion 21 are connected by a shoulder platform 23. The fixing portion 41 is annular and passes through the vertical portion 22, fitting against the shoulder platform 23. The first fastening portion 42 includes a plurality of spring pieces 429 extending outward and downward from the fixing portion 41. The plurality of spring pieces 429 are spaced apart on the outer periphery of the fixing portion 41, and the spring pieces 429 protrude outward from the vertical portion 22. The second fastening portion 53 is configured as a hook 53, which fastens upward to the spring piece 429. In this embodiment... The hook 53 is configured as an inverted ring structure. The first fastening part 42 includes a plurality of spring pieces 429 extending outward and downward from the fixing part 41. The hook 53 fastens upward onto the spring pieces 429 to enhance the stability of the engagement between the first fastening part 42 and the second fastening part 53. In one embodiment, the number of hooks 53 is less than the number of spring pieces 429, and the width of the hook 53 along the direction in which the spring pieces 429 are arranged is greater than the interval between two adjacent spring pieces 429. Because the number of hooks 53 is less than the width of the hooks 53 along the direction in which the spring pieces 429 are arranged is greater than the interval between two adjacent spring pieces 429, even if the spout 5 is rotated to any position relative to the outer shell 2, the engagement between the spring pieces 429 and the hook 53 can still be guaranteed. In other embodiments, the number of hooks 53 is the same as the number of spring pieces 429.

[0049] refer to Figures 11-14In another embodiment, the difference from the preferred embodiment lies in the structure of the fixing ring 41. Specifically, the outer shell 2 of the liquid insulation container of this utility model further includes a vertical portion 22 located below the second connecting portion 21. The vertical portion 22 is sleeved within the mounting cavity 51. The fixing portion 41 is sleeve-shaped and is sleeved outside the vertical portion 22.
