Description
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] Thermal insulation containers are generally used to store edibles such as food or beverages, and usually include a container body and a container cover. The container cover is detachably connected to the mouth of the container body, and the container body is generally provided with a vacuum interlayer to reduce heat loss and achieve a thermal insulation effect. However, this thermal insulation container can only reduce the heat loss of the edibles themselves. After long-term storage, the edibles lose heat and the temperature drops, which cannot meet the demand for long-term thermal insulation. Utility Model Content
[0003] The present application provides a thermal insulation container to meet the demand for long-term thermal insulation of the thermal insulation container.
[0004] The present application provides a heat-insulating container, which comprises:
[0005] A container body, wherein a container opening is provided on the top of the container body;
[0006] A heating plug is provided with a phase change material layer, the heating plug passes through the container mouth and is installed in the container body, and can slide along the axial direction of the container body.
[0007] The embodiment of the present application provides a heat preservation container, which includes a container body and a heating plug. The top of the container body is provided with a container mouth, and a phase change material layer is provided in the heating plug. The phase change material layer can release the stored heat into the container body, thereby increasing the internal temperature of the container body and playing a role in heat preservation or heating the items in the container body; the heating plug passes through the container mouth and is installed in the container body, so that the heating plug releases heat inside the container body to reduce heat loss. The heating plug can slide along the axial direction of the container body. The user can adjust the position of the heating plug in the container body according to the amount of items contained in the container body, thereby reducing the interval between the items and the heating plug, so that the heating plug can be heated as close to the items as possible, and improve the heat preservation and heating effect. In addition, as the items or gas in the container body expand and contract, the heating plug can also automatically slide in the container body, thereby adjusting the size of the space between the heating plug and the container body, balancing the internal and external air pressures, and preventing the pressure in the container body from being too high and causing danger.
[0008] Optionally, the heating plug includes a heat-insulating shell and a heat-conducting shell, wherein the heat-conducting shell is stacked at the bottom of the heat-insulating shell, and the phase change material layer is filled between the heat-insulating shell and the heat-conducting shell. The heat of the phase change material layer is transferred and released into the container body through the heat-conducting shell below to increase the heat dissipation area and improve the heating effect; the heat-insulating shell above plays a role of heat insulation to prevent the heat of the phase change material layer from being transferred upward and released to the outside air, thereby improving the utilization rate of heat.
[0009] Optionally, the heat-conducting shell is a cavity-shaped structure with an opening at the top, the phase change material layer is contained in the heat-conducting shell, and the heat-insulating shell is sealed and connected to the opening. The lower surface and the outer peripheral surface surrounding the phase change material layer are both heat-conducting surfaces, and the upper surface of the phase change material layer is a heat-insulating surface, so as to increase the contact area between the phase change material layer and the heat-conducting shell, so that the heat of the phase change material layer can be transferred and released into the container body as quickly as possible, further improving the heating effect.
[0010] Optionally, the heating plug further comprises a sealing ring, which is sleeved on the outer circumference of the heat insulating shell, and comprises a first sealing lip and a second sealing lip, wherein the first sealing lip is located above the second sealing lip; the first sealing lip elastically presses against the inner wall of the container body, and the second sealing lip elastically presses against the inner wall of the heat conductive shell. Through a sealing ring, both the external sealing of the heating plug and the internal sealing of the heating plug are achieved, which reduces the number of parts and reduces the production cost. Moreover, by clamping the sealing ring by the heat insulating shell and the heat conductive shell, the reliability of the sealing ring connection is also increased, which prevents the sealing ring from shifting or falling off during use, thereby affecting the sealing effect.
[0011] Optionally, the interior of the insulation shell has an insulation cavity, which increases the overall height of the insulation shell without increasing the weight of the insulation shell, thereby extending the path for heat transfer to the external air and improving the insulation effect.
[0012] Optionally, the heat insulation cavity is filled with heat insulation material to further block heat transfer and improve the heat insulation effect.
[0013] Optionally, a sealing ring is provided on the outer periphery of the heating plug, and the sealing ring elastically presses against the inner wall of the container body. On the one hand, a sealing fit is formed between the heating plug and the container body to prevent convection exchange between the hot air in the container body and the cold air outside, thereby reducing heat loss in the container body and improving the heat preservation effect; on the other hand, the sealing ring plays a damping role between the heating plug and the container body, increasing the sliding resistance of the heating plug, so that the heating plug can stay stably at a predetermined position, reducing the movement or shaking of the heating plug during use, thereby ensuring reliable heat preservation and heating effects.
[0014] Optionally, a grip portion is provided on the top of the heating plug to facilitate the user to lift the heating plug and insert the heating plug into the container body or take it out from the container body.
[0015] Optionally, the interior of the container body includes a uniform cross-section segment, the uniform cross-section segment extends along the axial direction of the container body, the cross section of the uniform cross-section segment remains unchanged, and the heating plug is installed on the uniform cross-section segment and slides along the uniform cross-section segment. The uniform cross-section segment guides the heating plug to ensure that the matching state of the heating plug and the container body remains unchanged within the movement range of the heating plug, thereby preventing the heating plug from shifting or tilting unexpectedly, resulting in heat loss in the container body.
[0016] Optionally, the thermal insulation container also includes a protective cover, which is detachably connected to the top of the container body. The heating plug is located in the space enclosed by the protective cover and the container body. It can not only play an axial limiting role on the heating plug, limit the highest sliding position of the heating plug in the container body, and effectively prevent the heating plug from escaping from the container body during use, but also play a protective role around the circumference of the heating plug, preventing the heating plug from being tilted or shifted by external force during use, thereby affecting the thermal insulation and heating effects of the thermal insulation container.

[0039] 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.
[0040] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] 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.
[0042] like Figure 1-Figure 4As shown, the embodiment of the present application provides a heat preservation container, which includes a container body 1 and a heating plug 2. A container mouth 11 is provided on the top of the container body 1 to facilitate users to store and take out items; a phase change material layer 25 is provided in the heating plug 2, and the phase change material layer 25 can release the stored heat into the container body 1, thereby increasing the internal temperature of the container body 1 and playing a role in heat preservation or heating the items in the container body 1; the heating plug 2 passes through the container mouth 11 and is installed in the container body 1, so that the heating plug 2 releases heat inside the container body 1 to reduce heat loss. The heating plug 2 can slide along the axial direction of the container body 1. The user can adjust the position of the heating plug 2 in the container body 1 according to the amount of items contained in the container body 1, thereby reducing the interval between the items and the heating plug 2, so that the heating plug 2 can be heated as close to the items as possible, thereby improving the heat preservation and heating effects. In addition, as the items or gas in the container body 1 expand and contract, the heating plug 2 can automatically slide in the container body 1, thereby adjusting the size of the space between the heating plug 2 and the container body 1, balancing the internal and external air pressures, and preventing the pressure in the container body 1 from being too high and causing danger.
[0043] Specifically, the phase change material layer 25 can be made of bio-based phase change material or TH-LS series solid-liquid phase change material, etc. The heating plug 2 absorbs and pre-stores heat in an environment with a higher external temperature. For example, the heating plug 2 can be placed in an environment with a higher temperature such as hot water, so that the phase change material layer 25 inside the heating plug 2 can fully absorb and store heat; the heating plug 2 with pre-stored heat releases heat in the container body 1, thereby being able to supplement the heat in the container body 1 and extend the insulation time of the insulation container.
[0044] The cross section of the heating plug 2 is not larger than the cross section of the container mouth 11, so that the heating plug 2 can completely pass through the container mouth 11 and be accommodated in the interior of the container body 1. Within the sliding stroke of the heating plug 2, the cross section of the heating plug 2 is not larger than the cross section of the interior of the container body 1, so that the heating plug 2 can slide freely in the interior of the container body 1.
[0045] In one embodiment, when the heating plug 2 is at the highest position of the sliding stroke, the top of the heating plug 2 can be higher than the top of the container body 1. At this time, a portion of the heating plug 2 extends out of the container mouth 11 to reduce the space occupied by the heating plug 2 in the container body 1 and increase the maximum available volume of the container body 1.
[0046] In another embodiment, when the heating plug 2 is at the highest position of the sliding stroke, the top of the heating plug 2 is not higher than the top of the container body 1. At this time, the heating plug 2 is completely located inside the container body 1 to ensure the matching length between the heating plug 2 and the container body 1, thereby ensuring that the heating plug 2 is reliably installed in the container body 1 and preventing the heating plug 2 from falling from the container mouth 11 due to external collision or internal steam pressure.
[0047] Furthermore, the interior of the container body 1 includes a uniform cross-sectional segment 12, which extends axially along the container body 1. The cross-sectional area (including shape and size, etc.) of the uniform cross-sectional segment 12 remains unchanged. The heating plug 2 is installed on the uniform cross-sectional segment 12 and slides along the uniform cross-sectional segment 12. The uniform cross-sectional segment 12 guides the heating plug 2 to ensure that the matching state of the heating plug 2 and the container body 1 remains unchanged within the movement range of the heating plug 2, thereby preventing the heating plug 2 from shifting or tilting unexpectedly, which would cause heat loss in the container body 1.
[0048] Further, the top of the uniform cross-sectional section 12 is aligned with the top of the container body 1, that is, the uniform cross-sectional section 12 extends downward from the container mouth 11, and the cross section of the uniform cross-sectional section 12 is the same as the cross section of the container mouth 11, so as to reduce the length requirement of the heating plug 2 extending into the container body 1, and increase the highest position of the bottom of the heating plug 2 as much as possible, thereby reducing the space occupied by the heating plug 2 in the container body 1, and thus increasing the maximum available volume of the container body 1. It can be understood that in other embodiments, the top of the uniform cross-sectional section 12 can also be lower than the top of the container body 1, that is, there is a gap between the uniform cross-sectional section 12 and the container mouth 11, so as to increase the length of the heating plug 2 extending into the container body 1 and prevent the heating plug 2 from falling from the container mouth 11.
[0049] Furthermore, the heat-insulating container further comprises a protective cover 3, which is detachably connected to the top of the container body 1. For example, the protective cover 3 and the container body 1 can be connected to each other by means of a threaded structure or a snap-fit structure. The heating plug 2 is located in the space enclosed by the protective cover 3 and the container body 1, which can not only play an axial limiting role for the heating plug 2, limiting the highest sliding position of the heating plug 2 in the container body 1, effectively preventing the heating plug 2 from falling out of the container body 1 during use, but also play a protective role around the circumference of the heating plug 2, preventing the heating plug 2 from being tilted or shifted by external forces during use, thereby affecting the heat preservation and heating effect of the heat-insulating container.
[0050] Specifically, the protective cover 3 includes a side portion and an end portion connected to each other. The side portion extends along the axial direction of the container body 1 and is used to connect the side wall of the container body 1, so as to achieve the installation and fixation of the protective cover 3; at least a part of the end portion extends to the top of the heating plug 2, so as to play a role of stopping and limiting above the heating plug 2.
[0051] In one embodiment, the side and the end form a closed cavity structure with an opening facing downward, that is, the protective cover 3 completely closes the container opening 11, which can not only increase the appearance of the thermal insulation container, but also play a role in dust prevention and heat insulation, thereby further improving the user experience of the thermal insulation container. Of course, in other embodiments, the side and the end can also form a frame structure or a mesh structure, that is, the protective cover 3 blocks a part of the container opening 11, as long as it can play an axial limiting role on the heating plug 2.
[0052] Furthermore, a sealing ring 4 is sleeved on the outer periphery of the heating plug 2, and the sealing ring 4 elastically presses against the inner wall of the container body 1. On the one hand, a sealing fit is formed between the heating plug 2 and the container body 1, and convection exchange between the hot air in the container body 1 and the cold air outside is avoided, thereby reducing the heat loss in the container body 1 and improving the heat preservation effect; on the other hand, the sealing ring 4 plays a damping role between the heating plug 2 and the container body 1, increasing the sliding resistance of the heating plug 2, so that the heating plug 2 can stay stably at a predetermined position, reducing the movement or shaking of the heating plug 2 during use, thereby ensuring reliable heat preservation and heating effects.
[0053] Furthermore, a gripping portion 23 is provided on the top of the heating plug 2 to facilitate the user to lift the heating plug 2 and put the heating plug 2 into or take it out of the container body 1. The gripping portion 23 can be configured as any appropriate protruding structure, such as a columnar, strip-shaped, block-shaped or hook-shaped structure, as long as it can be conveniently pinched by the user's fingers.
[0054] Furthermore, the gripping portion 23 is configured as a strip-shaped structure extending along the surface of the heating plug 2. On the one hand, the area of the gripping portion 23 can be increased within a limited operating space, thereby increasing the stability of the user in lifting the heating plug 2; on the other hand, it can prevent the heating plug 2 from slipping off due to the rotation of the user's fingers when the user lifts the heating plug 2. In addition, the strip-shaped structure provided on the top of the heating plug 2 can also play a reinforcing role, increase the overall structural strength of the heating plug 2, and reduce the risk of deformation or damage of the heating plug 2.
[0055] Furthermore, a groove 24 is provided on the top of the heating plug 2, and the gripping portion 23 is protruded in the groove 24. Without increasing the overall height of the heating plug 2, the effective height of the gripping portion 23 is increased, thereby increasing the stability of the user in lifting the heating plug 2 and preventing the heating plug 2 from accidentally slipping off.
[0056] Furthermore, the heating plug includes a heat-insulating shell 21 and a heat-conducting shell 22, wherein the heat-conducting shell 22 is stacked at the bottom of the heat-insulating shell 21, and the phase change material layer 25 is filled between the heat-insulating shell 21 and the heat-conducting shell 22. The heat of the phase change material layer 25 is transferred and released into the container body through the heat-conducting shell 22 below, so as to increase the heat dissipation area and improve the heating effect; the heat-insulating shell 21 above plays a role of heat insulation, preventing the heat of the phase change material layer 25 from being transferred upward and released to the outside air, thereby improving the utilization rate of heat.
[0057] Furthermore, the heat-conducting shell 22 is a cavity-like structure with an opening at the top, the phase change material layer 25 is accommodated in the heat-conducting shell 22, and the heat-insulating shell 21 is sealed and connected to the opening, that is, the lower surface and the outer peripheral surface surrounding the phase change material layer 25 are both heat-conducting surfaces, and the upper surface of the phase change material layer 25 is a heat-insulating surface, so as to increase the contact area between the phase change material layer 25 and the heat-conducting shell 22, so that the heat of the phase change material layer 25 can be transferred and released into the container body as quickly as possible, further improving the heating effect.
[0058] In one embodiment, the sealing ring 4 is sleeved on the outer periphery of the heat insulating shell 21, and a part of the sealing ring 4 is clamped between the heat insulating shell 21 and the heat conductive shell 22. The sealing ring 4 includes a first sealing lip 41 and a second sealing lip 42, and the first sealing lip 41 is located above the second sealing lip 42. The first sealing lip 41 elastically presses against the inner wall of the container body, and the second sealing lip 42 elastically presses against the inner wall of the heat conductive shell 22. Through a sealing ring 4, the external sealing of the heating plug (i.e., the sealing between the heating plug and the container body) and the internal sealing of the heating plug (i.e., the sealing between the heat insulating shell 21 and the heat conductive shell 22) are simultaneously realized, which reduces the number of parts and reduces the production cost. Moreover, by clamping the sealing ring 4 by the heat insulating shell 21 and the heat conductive shell 22, the reliability of the connection of the sealing ring 4 is also increased, and the sealing ring 4 is prevented from shifting or falling off during use, which affects the sealing effect. It can be understood that in other embodiments, a separate sealing ring can also be set between the heat insulating shell 21 and the heat conductive shell 22.
[0059] Furthermore, the bottom surface of the heat-conducting shell 22 is a concave-convex surface 221. For example, the bottom surface of the heat-conducting shell 22 can be an annular wavy surface or a step surface, etc., so as to increase the structural strength of the heat-conducting shell 22 and prevent the heat-conducting shell 22 from deforming or breaking, which causes the phase change material layer 25 to leak during repeated solid-liquid phase changes.
[0060] Furthermore, the interior of the heat-insulating shell 21 is provided with a heat-insulating cavity, and the overall height of the heat-insulating shell 21 is increased without increasing the weight of the heat-insulating shell 21, thereby extending the path for heat transfer to the external air and improving the heat-insulating effect.
[0061] Furthermore, the heat insulation cavity is filled with heat insulation material 26, for example, PE polystyrene, foaming agent or heat insulation cotton and other materials with heat insulation function, to further block heat transfer and improve the heat insulation effect. It can be understood that the heat insulation cavity can also adopt any appropriate closed cavity structure such as vacuum cavity.
[0062] 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.
