Description
Technical Field
The utility model relates to a container especially relates to a threaded connection's double-deck container of thermal-insulated heat preservation.
Background
Because the ceramic or glass has the characteristics of no corrosion, no deformation, easy cleaning, safety and sanitation, the ceramic or glass is an ideal material for manufacturing daily utensils such as tableware, cups and the like; however, single-layer ceramic or glass has poor heat preservation and insulation effects, and particularly tableware used by children often has scalding accidents when being used or can not be endured and dropped after being held up; therefore, people often make ceramic or glass ware such as bowls, cups and the like into a double-layer structure, namely, a shell is sleeved outside the ceramic or glass ware and is mostly made of plastic, bakelite, wood or stainless steel materials; however, the fixed connection between the shell and the ceramic or glass vessel is always a difficult problem, and some of the shells adopt a more complicated connection structure, which not only increases the production and installation difficulty, but also increases the production cost; therefore, the connection with the shell is mostly realized by adopting the convenient adhesive, but the adhesive is easy to age and fall off after being used for a period of time, so that the adhesive cannot be used, the waste is caused, and the inconvenience is brought to the life of people.
Disclosure of Invention
In order to overcome the defects, the utility model aims to provide a double-layer structure which can ensure that the inner container made of ceramics or glass and the shell made of other materials form is convenient to install, has simple structure, good heat insulation effect, no scalding, difficult damage and convenient use and carrying.
The utility model provides a technical scheme that its technical problem adopted is: a double-layer container with heat insulation and preservation in threaded connection comprises a circular inner container and a circular outer shell, wherein the inner container is provided with an upward opening, the edge of the opening is bent downwards after extending outwards, and an insertion groove is formed between the inner container and the outer wall of the inner container; the method is characterized in that: an annular convex ring is arranged at the bottom of the inner container, and external threads are arranged on the outer side of the annular convex ring; the outer shell is matched with the inner container and is slightly larger than the inner container, and the mouth part of the outer shell is sleeved in the inserting groove of the inner container; the bottom of the shell is provided with a circular groove, the inner side of the circular groove is provided with an internal thread, the internal thread is matched and in threaded connection with the external thread of the annular convex ring, and the circular shell is connected and fastened with the circular inner container.
And a sealing ring is arranged in the insertion groove of the circular inner container, so that the mouth part of the circular outer shell is hermetically connected with the inner container.
The circular shell is made of plastic, bakelite or stainless steel materials.
The inner vessel is made of a ceramic or glass material.
And reinforcing ribs are arranged on the inner side of the circular shell.
The reinforcing ribs arranged on the inner side of the circular shell are vertically and uniformly arranged, and the number of the reinforcing ribs is not less than two.
Realize the utility model discloses, because the bottom of inner container is equipped with the annular bulge loop of outband screw thread, is provided with the circular recess of in-band screw thread in the shell bottom, makes the bilayer structure who constitutes by the inner container that pottery or glass made and the shell of other materials connect fastening, simple structure, reasonable, and the production and the installation of being convenient for, durable, and thermal-insulated, keep warm effectually, do not scald one's hand, be difficult to break, use and convenient to carry are particularly suitable for children's tableware, and containers such as thermos cup satisfy people daily life's needs.
Drawings
Fig. 1 is a schematic view of the structural principle of the threaded connection heat insulation double-layer container of the present invention.
Detailed Description
The structural principle of the present invention will be described in further detail with reference to the accompanying drawings:
a double-layer container with heat insulation and preservation in threaded connection comprises a circular ceramic inner container 1 and a circular plastic shell 2, wherein the opening of the ceramic inner container 1 is upward, the edge 11 of the opening is bent downward after extending outward, and an inserting groove 12 is formed by the ceramic inner container and the outer wall of the ceramic inner container; an annular convex ring 13 is arranged at the bottom of the ceramic inner container 1, and an external thread 14 is arranged on the outer side of the annular convex ring 13; the circular plastic shell 2 is matched with the circular ceramic inner container 1 and is slightly larger than the circular ceramic inner container 1, and the mouth part 21 of the circular plastic shell 2 is sleeved in the insertion groove 12 of the ceramic inner container; a circular groove 22 is formed in the bottom of the shell, an internal thread 23 is formed in the inner side of the circular groove 22, the internal thread 23 is matched with and screwed with the external thread 14 of the annular convex ring, and the circular shell 2 and the circular ceramic inner container 1 are connected and fastened; a sealing ring 3 is arranged in the inserting groove 12 of the circular ceramic inner container 1, so that the opening part 21 of the circular outer shell is hermetically connected with the circular ceramic inner container 1.
The above illustration is only one embodiment of the present invention, and it should be noted that the ordinary changes and substitutions by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
