Technical Field
[0001] The present application relates to the technical field of daily necessities, and in particular to a thermal insulation container. Background Art
[0002] The heat-insulating container generally includes a container body and a container cover, and the container cover is detachably connected to the mouth of the container body. Existing heat-insulating containers mainly improve the container body to achieve the heat-insulating effect. For example, the container body generally includes an outer shell, an inner liner, and an interlayer between the outer shell and the inner liner. The interlayer is generally a vacuum interlayer, thereby reducing heat loss and achieving the heat-insulating effect. However, the mouth of the container body is generally closed by the container cover, and the heat loss is relatively large, resulting in the heat-insulating effect of the existing heat-insulating containers being difficult to meet the use requirements.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0043] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.
[0044] like Figure 1-Figure 3 As shown, an embodiment of the present application provides a thermal insulation container, which includes a container body 1, and the container body 1 is used to contain liquids such as hot water. The mouth of the container body 1 can be closed by a container cover 3, so that the interior of the thermal insulation container forms a sealed cavity.
[0045] Specifically, the mouth of the container body 1 includes a sealing section 11 and a connecting section 13. The inner wall of the sealing section 11 contracts radially to form a sealing convex rib 111, which can cooperate with the container cover 3. For example, the sealing convex rib 111 and the sealing ring 31 at the lower part of the container cover 3 are pressed against each other to achieve a sealed fit between the container cover 3 and the container body 1, that is, at least a part of the container cover 3 is embedded in the mouth of the container body 1 for sealing; the connecting section 13 is provided with a connecting structure 131 (for example, a threaded structure or a buckle structure, etc.), which can be directly connected to the container cover 3 or indirectly connected to the container cover 3 to achieve a connection and fixation between the container cover 3 and the container body 1.
[0046] The container body 1 includes an outer shell 1a and an inner liner 1b which are nested with each other. In each embodiment of the present application, the inner wall refers to the inner wall of the inner liner 1b, and the outer wall refers to the outer wall of the outer shell 1a. The outer shell 1a and the inner liner 1b form a joint 14 (for example, a welding joint 14, etc.) at the top of the container body 1, so that the outer shell 1a and the inner liner 1b are connected to each other to form a whole; a vacuum interlayer 1c is formed between the outer shell 1a and the inner liner 1b to achieve the heat preservation effect of the container body 1; the vacuum interlayer 1c can be filled with heat insulation material to further improve the heat preservation effect of the container body 1. The connecting section 13 is a section below the joint 14, that is, the joint 14 does not play a connecting role to ensure the reliability of the connection.
[0047] Furthermore, the mouth of the container body 1 also includes an extension section 12, which extends along the height direction of the container body 1, the sealing section 11 is formed at the lower end of the extension section 12, and the connecting section 13 is formed at the upper end of the extension section 12, so that the sealing section 11 and the connecting section 13 are arranged along the height direction of the container body 1, and the sealing section 11 and the connecting section 13 form a larger axial interval through the extension section 12, thereby increasing the depth of the mouth of the container body 1; the container cover 3 passes through the connecting section 13 and the extension section 12 in turn, and then forms a sealing fit with the sealing section 11, thereby increasing the depth of the container cover 3 embedded in the mouth of the container body 1. Since the container cover 3 is usually a poor conductor of heat, the embodiment of the present application can reduce the heat conduction of the liquid in the container body 1 along the container cover 3, thereby improving the thermal insulation performance of the thermal insulation container.
[0048] Further, the sealing section 11, the extension section 12 and the connecting section 13 are integrally formed at the mouth of the container body 1, that is, the outer shell 1a and the inner liner 1b of the container body 1 are respectively an integral structure, and the integral structure can avoid the formation of connection structures such as welds, which can not only improve the structural strength and sealing performance of the container body 1 itself, but also form a surface that is easy to clean, thereby improving the cleaning performance of the container body 1. It can be understood that in other embodiments, the sealing section 11 can be formed at the mouth of the container body 1 by welding or the like, the sealing section 11 can be formed at the lower end of the extension section 12 by welding or the like, and the connecting section 13 can be formed at the lower end of the extension section 12 by welding or the like, as long as the container body 1, the sealing section 11, the extension section 12 and the connecting section 13 can be sequentially connected to form a sealed whole.
[0049] Furthermore, the sealing rib 111 and the extension section 12 may be connected by an arc surface; the sealing rib 111 and the container body may be connected by an arc surface, so that the mouth of the container body forms a smooth and gentle surface, which can avoid damage due to stress concentration, and can also avoid dirt and grime, thereby improving the convenience of cleaning.
[0050] Further, the distance L1 between the sealing rib 111 and the top of the container body 1 is 25 mm to 50 mm. For example, the distance L1 between the sealing rib 111 and the top of the container body 1 can be 25 mm, 30 mm, 32 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 48 mm or 50 mm, etc., which can effectively improve the thermal insulation performance of the thermal insulation container and ensure the user experience of the thermal insulation container. When the distance L1 between the sealing rib 111 and the top of the container body 1 is less than 25 mm, the thermal insulation performance of the thermal insulation container is difficult to meet the requirements; when the distance L1 between the sealing rib 111 and the top of the container body 1 is greater than 50 mm, the thermal insulation effect is not significantly improved, and the external volume of the thermal insulation container is larger and the actual effective volume is smaller, which affects the user experience of the thermal insulation container.
[0051] Further, the inner diameter L2 of the sealing rib 111 is 30 mm to 80 mm. For example, the inner diameter L2 of the sealing rib 111 can be 30 mm, 33 mm, 35 mm, 40 mm, 45 mm, 50 mm, 52 mm, 54 mm, 56 mm, 58 mm, 60 mm, 62 mm, 64 mm, 66 mm, 68 mm, 70 mm, 75 mm or 80 mm, etc., which can not only ensure the user experience of the thermal insulation container, but also effectively improve the thermal insulation performance of the thermal insulation container. When the inner diameter L2 of the sealing rib 111 is less than 30 mm, the water outlet cross section of the container body 1 is too small, which affects the smoothness of the water outlet and further affects the user experience of the thermal insulation container; when the inner diameter L2 of the sealing rib 111 is greater than 80 mm, the cross-sectional area of the mouth of the container body 1 is too large, resulting in a large heat dissipation area of the mouth of the container body 1, which affects the thermal insulation effect of the thermal insulation container.
[0052] The above values are only preferred modes in this embodiment. It can be understood that in other embodiments, the distance between the sealing rib 111 and the container body 1 and the inner diameter of the sealing rib 111 can be other preferred values. For example, in a large-capacity thermos pot, the distance between the sealing rib 111 and the container body 1 can be set to a height of 55 mm / 60 mm, etc., and the inner diameter of the sealing rib 111 can be set to 85 mm, etc.
[0053] Furthermore, the length of the extension section 12 is greater than the length of the connection section 13. On the one hand, the extension section 12 is a smooth surface without a matching structure, and the structure is simple and easy to implement, so that the depth of the mouth of the container body 1 can be effectively increased to achieve the expected heat preservation effect; on the other hand, the original connection structure 131 can be retained as much as possible, that is, it is only necessary to raise the position of the original connection structure 131, so as to ensure a reliable connection effect and reduce production costs.
[0054] Furthermore, the connection structure 131 is arranged on the outer wall of the connection section 13 to simplify the inner wall structure of the mouth of the container body 1, reduce the heat dissipation area of the mouth, thereby further reducing the heat dissipated from the mouth of the container body 1 and improving the heat preservation effect of the container body 1. Specifically, the inner liner 1b of the container body 1 is in direct contact with the liquid for heat conduction, so that the inner liner 1b forms a heat dissipation channel at the mouth. The larger the surface area of the inner liner 1b at the mouth, the more heat is dissipated through the mouth of the inner liner 1b. The connection structure 131 is arranged on the outer shell 1a that is not in contact with the liquid, which can reduce the surface area of the inner liner 1b at the mouth, thereby reducing the heat dissipated from the mouth of the container body 1.
[0055] Furthermore, the connecting structure 131 is a card slot opened on the outer wall of the connecting section 13, that is, the components installed and fixed on the connecting section 13 (for example, components such as the mounting seat 2) can be provided with a rigid card protrusion 21, and the card protrusion 21 is inserted into the card slot to form a rigid fit, thereby stably connecting the components installed and fixed on the connecting section 13 to the container body 1, preventing the user from misoperating and causing the components installed on the connecting section 13 to loosen or fall off, thereby affecting the safety of use of the thermal insulation container.
[0056] Furthermore, the inner diameter of the connecting section 13 is the same as the inner diameter of the extending section 12, that is, the inner wall of the connecting section 13 and the inner wall of the extending section 12 are connected to each other to form a smooth and flat continuous surface, which can not only minimize the surface area and cross-sectional area of the mouth of the container body 1 and reduce the heat dissipated from the mouth of the container body 1, but also reduce the installation resistance of the container cover 3, so that the container cover 3 can be more easily installed and removed.
[0057] Furthermore, the outer diameter of the connecting section 13 is smaller than the outer diameter of the extending section 12, thereby forming an annular installation space at the periphery of the connecting section 13, and the components fixed to the connecting section 13 can be embedded in the installation space, thereby improving the appearance and integrity of the thermal insulation container.
[0058] Furthermore, an annular step surface 132 is formed between the outer wall of the connecting section 13 and the outer wall of the extending section 12, and the step surface 132 is used to axially limit the components installed and fixed on the connecting section 13, thereby increasing the stability of the connection and preventing the container cover 3 and other components from axially moving and affecting the sealing effect of the container cover 3.
[0059] Furthermore, along the direction away from the axis of the container body 1, the height of the step surface 132 gradually decreases, which can not only form a certain axial avoidance space to ensure that the components installed and fixed on the connecting section 13 can be installed in place, but also play a certain radial limiting role to reduce the possible shaking of the components installed and fixed on the connecting section 13.
[0060] Furthermore, the heat preservation container further includes a mounting seat 2, which is arranged at the mouth of the container body 1 and is connected and fixed to the connecting section 13. The mounting seat 2 is used to connect the container cover 3, that is, the container cover 3 is indirectly connected to the mouth of the container body 1 through the mounting seat 2. The mounting seat 2 can cover the joint 14 at the top of the container body 1 to prevent the joint 14 from being exposed, thereby improving the appearance of the heat preservation container. In addition, the mounting seat 2 can also be conveniently provided with a water outlet 22 to facilitate pouring out the internal liquid; the mounting seat 2 can also be provided with a handle 23 to facilitate the user to hold and lift the heat preservation container, thereby further improving the convenience of using the heat preservation container.
[0061] Furthermore, the thermal insulation container also includes a container cover 3, which is embedded in the mounting seat 2, that is, the container cover 3 is embedded in the mouth of the container body 1 and the mounting seat 2 at the same time, which further increases the embedding depth of the container cover 3 and improves the thermal insulation performance of the thermal insulation container; the container cover 3 is detachably connected to the mounting seat 2 to avoid the non-metallic container cover 3 being directly connected and fixed to the metal container body 1, which causes bumps or wear of the container cover 3 during repeated disassembly and assembly, affecting the reliability of the connection of the container cover 3.
[0062] In a specific embodiment, the volume of the heat preservation container is 2.0L, the distance L1 between the sealing rib 111 and the top of the container body 1 is 40mm, and the inner diameter L2 of the sealing rib 111 is 60mm. A group of the heat preservation container and multiple groups of existing 2.0L heat preservation containers are tested for their heat preservation performance according to the following process:
[0063] Place the thermal insulation container at an ambient temperature of 20℃±5℃ for more than 30 minutes, and then fill it with boiling water (100℃) to the lower end of the sealing cover (plug); when the actual measured temperature of the water in the thermal insulation container reaches 95℃±1℃, tighten the seal immediately. Under the same environmental conditions, measure the water temperature in the thermal insulation container after 12 hours. The test results show that the water in the thermal insulation container can maintain an average water temperature of 79.5℃ after 12 hours, and the thermal insulation effect is significantly higher than that of the existing 2.0L thermal insulation container (about 71.2℃~77℃).
[0064] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
