Description

[Technical Field]

[0001] The present invention relates to the technical field of household goods, and more particularly to a thermos pot body and a thermos pot. [Background technology]

[0002] Currently, commercially available thermoses consist of a stainless steel body connected to a plastic head. The connection method is generally a connection between the external threads of the stainless steel body, the external ribs of the stainless steel body, or the welded parts of the stainless steel body and the plastic material. To ensure the strength of the connection, it is necessary to provide more than one round of threads. Since the threads have a certain pitch, a large surface area of ​​the plastic head is exposed, requiring more plastic material, and the external design is limited, resulting in a monotonous appearance. Summary of the Invention

[0003] The present invention aims to provide a thermos pot body and a thermos pot, in which the plastic spout and the stainless steel body use an internal reverse-engagement directional connection method, which has a safe structure, high reliability, and an overall beautiful appearance.

[0004] In order to achieve the above object, the technical means used in the present invention is a thermos pot body, characterized in that a sealing ring is attached to the plastic spout, a circular snap is provided at the lower end of the plastic spout, a circular locking portion that engages with the circular snap is provided on the stainless steel body, a sloped inner wall that cooperates with the sealing ring is provided at the upper end of the neck of the stainless steel body, a positioning sheet is fixed to the stainless steel body, and a positioning groove that fits into the positioning sheet of the stainless steel body is provided on the plastic spout.

[0005] Furthermore, a plurality of breaking grooves are provided at the engagement point between the snap and the locking portion at the bottom of the plastic spout.

[0006] Furthermore, the stainless steel body includes a case to which a handle is connected and an inner bottle fixed within the case.

[0007] Furthermore, the positioning sheet is fixed to the inner bottle and its position corresponds to the handle.

[0008] Furthermore, the annular locking portion is provided on the neck of the inner bottle.

[0009] The present invention further discloses a thermos pot comprising the thermos pot body and a lid that can be combined with the thermos pot body.

[0010] The beneficial effect of this invention is that, after the annular snap at the bottom of the plastic spout is engaged with the stainless steel body in a snap-fit ​​manner, the compressive thrust of the sealing ring firmly engages the plastic spout with the stainless steel body, tightly adhering the sealing ring to the inner wall of the inclined neck of the stainless steel body to prevent water leakage. Not only does this ensure structural stability, it also significantly reduces the amount of exposed plastic material on the spout, improving product design options, improving overall aesthetics and avoiding the risk of water leakage caused by deformation of ordinary PP plastic during injection molding.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will now be described in more detail with reference to the drawings.

[0013] As shown in Figures 1 to 5, the thermos pot body of the present invention includes a plastic spout 2 and a stainless steel body 3, and the stainless steel body 3 includes a case to which a handle 1 is connected and an inner bottle fixed within the case.

[0014] A sealing ring 21 is attached to the plastic spout 2, and a circular snap 22 is provided at the bottom end of the plastic spout 2. A sloped inner wall 31 and a circular locking portion 32 are provided at the neck of the inner bottle of the stainless steel body 3, and the circular locking portion 32 can engage with the circular snap 22. After the stainless steel body 3 and the plastic spout 2 are engaged, the compressive thrust of the sealing ring 21 causes the plastic spout 2 to tightly adhere to the sloped inner wall 31, achieving a tight seal.

[0015] 6 and 7, a positioning sheet 42 is fixed to the stainless steel body 3, a positioning groove 41 is provided on the plastic spout 2 to fit into, and the positioning sheet 42 is fitted into the positioning groove 41, thereby realizing the alignment of the water outlet of the plastic spout with the handle and preventing rotation. Specifically, the positioning sheet 42 is fixed to the inner bottle, and is attached on the same side as the handle, facing the water outlet part 51 of the plastic spout 2.

[0016] Preferably, the snap at the bottom of the plastic spout is provided with a plurality of breakage grooves 52 where the snap engages with the latch. As shown in Figure 8, the provision of breakage grooves 52 allows the liquid in stainless steel body 3 to flow out through breakage grooves 52 when pouring it out, significantly reducing the amount of liquid 61 remaining in the pot body.

[0017] Specifically, during the assembly process, the positioning groove 41 of the plastic spout 2 and the positioning sheet 42 of the stainless steel body 3 are aligned and pre-assembled, and when the top surface of the plastic spout 2 is crimped and passes through the annular locking part 32, downward pressure causes the lower end of the plastic spout 2 to be injected and deformed inward, and after the annular snap 22 passes through the annular locking part 32, it recovers its deformation and engages with the annular locking part 32 to form a reverse-engagement lock, and also achieves a seal between the sealing ring 21 assembled on the plastic spout and the sloped inner wall 31 of the neck of the inner bottle in the stainless steel body.

[0018] The present invention further discloses a thermos pot including the thermos pot body and a lid that is combined with and attached to the thermos pot body.

[0019] The above content is only for illustrating the technical means of the present invention, and any simple modifications or equivalent substitutions to the technical means of the present invention by those skilled in the art will not depart from the spirit and scope of the technical means of the present invention.
