Abstract
A double-layer square insulated container includes a cuboid container body, which includes an inner liner and an outer shell, between which a vacuum layer is arranged. Reinforcing ribs are arranged on each of the inner liner and the outer shell and can make a surface of the square container evenly stressed during vacuumizing to avoid being crushed by suction. Reinforcing ribs are added to a surface of a mold. When the height of the reinforcing ribs is set to about 2 mm, the square surface is evenly stressed. Moreover, by repeated tests, the thickness of the inner liner and the outer shell is only about 0.5 mm, such that the weight of the square container is greatly reduced. Reinforcing ribs in different shapes are added to the periphery and bottom surface of the square container, which ensures support force of steel walls and improves the appearance.
Description
- This application is based upon and claims priority to Chinese Patent Application No. 202123353838.3, filed on Dec. 29, 2021, the entire contents of which are incorporated herein by reference.
- The present disclosure relates to the technical field of molds, in particular to a double-layer square insulated container.
- An existing double-layer vacuum insulated container is welded by inner and outer stainless steel, and air between an inner liner and an outer shell is extracted by a vacuum furnace to form an inside vacuum layer. The vacuum layer cuts off heat conduction between inside and outside to keep warm and cold. Due to atmospheric pressure, the inner and outer stainless steel needs to maintain a certain strength to ensure that it will not be crushed. It can be seen from the physical principle that support force in all directions of an arc surface is evenly distributed to ensure that the vacuum layer is not crushed by suction more simply. The existing square container has four flat surfaces at the periphery and four corners in arc transition, which will cause the entire surface to be unevenly stressed. The support force is relatively strong for the four corners, but is relatively weak for the flat surfaces, such that the middles of the flat surfaces are recessed downwards to affect both overall appearance and vacuum effect.
- In general, the thickness of a material is increased to solve the above problems in the market. But the cost, and the weight of a container body are increased, thus affecting customer experience and market competitiveness.

- In order to achieve the above objective, the present disclosure adopts the following technical solution:
- A double-layer square insulated container, including a container body, where the container body is in the shape of a cuboid as a whole, and includes an inner liner and an outer shell; a vacuum layer is arranged between the inner liner and the outer shell; reinforcing ribs are arranged on each of the inner liner and the outer shell; and the reinforcing ribs can make a surface of the square container evenly stressed during vacuumizing to avoid being crushed by suction.
- Preferably, the thickness of the outer shell is 0.48 mm-0.60 mm.
- More preferably, the thickness of the inner liner is 0.45 mm-0.55 mm.
- More preferably, the height of the reinforcing ribs is 1.5 mm-2.2 mm.
- Preferably, container opening reinforcing ribs are arranged on two opposite side walls of a container opening of the outer shell to avoid deformation during vacuumizing.

- Preferably, reinforcing ribs are further arranged at the bottom of each of the inner liner and the outer shell.
- Preferably, the outer shell is fixedly arranged outside the inner liner by welding, and welding points between the outer shell and the inner liner are distributed around the container opening.
- More preferably, a bottom of the outer shell is formed with vacuum holes.
- Compared with the prior art, the present disclosure has the following beneficial effects:
- According to the present disclosure, reinforcing ribs are added to a surface of a mold, and when the height of the reinforcing ribs is set to about 1.5 mm-2.2 mm (no effect for 1 mm, and poor appearance after molding for 3 mm), the square surface is evenly stressed to avoid being crushed by suction. Moreover, by repeated tests, the thickness of the inner liner and the outer shell is only about 0.5 mm, such that the weight of the square container is greatly reduced. Reinforcing ribs in different shapes are added to the periphery and bottom surface of the square container, which ensures support force of steel walls and improves the appearance.

- As shown in
FIGS. 1-4 , a double-layer square insulated container includes a container body 2; the container body 2 is in the shape of a cuboid as a whole, and the container body 2 includes an inner liner and an outer shell; a bottom 4 of the outer shell is formed withvacuum holes 41; a vacuum layer 1 is arranged between the inner liner and the outer shell; the outer shell is fixedly arranged outside the inner liner by welding; and welding points 8 between the outer shell and the inner liner are distributed around a container opening. Reinforcing ribs 6 are arranged on a side wall 7 of each of the inner liner and the outer shell; and the reinforcing ribs 6 can make a surface of the square container evenly stressed during vacuumizing to avoid being crushed by suction. The container opening 5 of the outer shell is provided with container opening reinforcing ribs 3, and the container opening reinforcing ribs 3 are arranged on two opposite side walls 7 of the container opening of the outer shell to avoid deformation during vacuumizing. Support surfaces of the container opening reinforcing ribs 3 must be perpendicular to each other, in other words, the inclination of the support surfaces will cause the side walls 7 to be stressed, which greatly reduces the support strength. In this embodiment, the container opening reinforcing ribs 3 are triangular, and two right-angle sides are respectively located on thickness difference platforms between the side walls of the container opening 5 and the side walls 7, and between the container opening 5 and the side walls 7. Reinforcing ribs 6 are further arranged at the bottom of each of the inner liner and the outer shell. - The thickness of the outer shell is 0.48 mm-0.60 mm, the thickness of the inner liner is 0.45 mm-0.55 mm, and the height of the reinforcing ribs 6 is 1.5 mm-2.2 mm. By repeated tests, the thickness of the inner liner and the outer shell is only about 0.5 mm, such that the weight of the square container can be greatly reduced. In this embodiment, the thickness of both the inner liner and the outer shell is 0.5 mm, and the height of the reinforcing ribs 6 is set to 2 mm. By tests, the reinforcing ribs 6 have no effect for 1 mm and are not attractive after molding for 3 mm.
-
FIG. 3 is an arrangement mode of reinforcing ribs 6 on a side wall 7 provided in this embodiment, andFIG. 4 is another arrangement mode of the reinforcing ribs 6. The specific arrangement mode of the reinforcing ribs 6 can be adjusted according to different needs. In this embodiment, both the inner liner and the outer shell of the container body 2 are made of food-grade stainless steel, and reinforcing ribs 6 in different shapes are added to the periphery and bottom surface of the container body 2, which ensures support force of steel walls and improves the appearance. - Obviously, the above-mentioned embodiments of the present disclosure are only examples for describing the present disclosure more clearly, rather than limiting an implementation mode of the present disclosure. For those of ordinary skill in the art, other variations or changes in different forms can be made on the basis of the above description. It is impossible to list all implementation methods here. The obvious variations or changes derived from the technical solutions of the present disclosure still fall within the scope of protection of the present disclosure.
