Description

Technical Field

[0001] The present invention relates to the field of heat preservation container technology, and particularly to a set of portable heat preservation cups.

Background Art

[0002] The conventional design of a set of heat preservation cups is used to maintain the low-temperature or high-temperature state inside the cup during portability, and users can conveniently perform treatments such as cold compress or hot compress and other cooling applications in various situations. Such a device is generally composed of a container and a heat storage member, supports the realization of refrigeration cooperation and heating functions in a mobile environment, and meets the needs of medical first aid or daily temperature rise and fall.

[0003] However, the set of heat preservation cups in the prior art generally has the problem that the operation of attaching and detaching the heat storage member is cumbersome. Only when the user repeatedly adjusts multiple members during use can the insertion and extraction process be completed, which not only increases the operation time but also makes it easy for the heat storage member to be displaced or accidentally fall off during portability due to unreasonable structural design. Moreover, the fixing method between the heat storage member and the container lacks flexibility, making it difficult for the user to quickly take out or reinstall the heat storage member in an emergency, which greatly affects the convenience and reliability of use.

[0017] The following describes preferred embodiments of the present invention with reference to the drawings, which constitute part of the present invention and are used together with the embodiments to interpret the principles of the present invention, and do not limit the scope of the present invention.

[0018] The portable heat-insulating cup set in this embodiment relates to the field of heat-insulating container technology. A heat storage body 300 is installed. One end of the heat storage body 300 is inserted into the outer cup 100, and the other end of the heat storage body 300 is removably connected to the lid body 200. It can realize the rapid installation and removal of the heat storage body 300, prevent the displacement and dropping of the heat storage body 300, and has high convenience and reliability in use.

[0019] Referring to FIGS. 1 to 6, the portable heat-insulating cup set in this embodiment includes an outer cup 100, a lid body 200 and a heat storage body 300. The outer cup 100 has a heat-insulating intermediate layer and can block the heat transfer. The lid body 200 and the outer cup 100 can be removably connected, realizing the rapid removal of the lid body 200 and the outer cup 100, allowing operation with one hand, and simplifying the opening and closing flow of the lid body 200.

[0020] The lid body 200 seals the opening of the outer cup 100 and can protect the internal assembly from the external environment.

[0021] The heat storage body 300 absorbs the heat of the surrounding environment, realizes the effect of heating up or cooling down, and can maintain the high and low temperature or cold and hot wet compress of the article. One end of the heat storage body 300 is inserted into the outer cup 100, and the outer cup 100 forms a relatively stable refrigeration or heat storage environment for the heat storage body 300, and can maintain the low temperature or high temperature state of the heat storage body 300. The other end of the heat storage body 300 is removably connected to the lid body 200, and the heat storage body 300 can be exchanged and maintained when necessary. The heat storage body 300 can be affected by the action of the lid body 200, and it is easy to move the heat storage body 300.

[0022] One practical application is when a user needs to carry an ice pack and apply a cold compress to alleviate muscle discomfort that may occur during outdoor activities. The user first pre-cools the heat storage body 300 by placing it in a refrigerator to allow the refrigerant inside to cool sufficiently. After the heat storage body 300 reaches the desired low temperature, the user inserts one end of the heat storage body 300 into the outer cup 100. Because the outer cup 100 has an insulating intermediate layer, it effectively blocks heat transfer from the external environment, thereby providing the heat storage body 300 with a stable low temperature environment and extending the cooling time of the heat storage body 300. The user then detachably connects the other end of the heat storage body 300 to the lid 200.

[0023] At this time, the insulated cup set is in a portable state, and the heat storage body 300 maintains a low temperature with the insulating protection of the outer cup 100. If the user needs to use an ice pack to apply a cold compress, they only need to operate the connection between the lid 200 and the outer cup 100, for example, by rotating or pressing to remove the lid 200 from the outer cup 100. Because the heat storage body 300 and the lid 200 are detachably connected, the heat storage body 300 can be removed together with the lid 200, or the heat storage body 300 can be easily exposed after the lid 200 has been removed, and the user can easily separate it from the lid 200 and use it.

[0024] Throughout the entire process, the user does not need to directly contact the cold heat storage body 300, nor does they need to search for the external cup 100, significantly improving ease of use.

[0025] One practical application is when a user needs to carry a hot bag to apply a hot compress, addressing injuries caused by rheumatism and muscle fatigue that may occur during work or activity. The user first heats the heat storage body 300 by placing it in hot water to allow the heat storage medium inside to store sufficient heat. After the heat storage body 300 reaches the desired high temperature, the user inserts one end of the heat storage body 300 into the outer cup 100. Because the outer cup 100 has an insulating intermediate layer, it effectively blocks heat transfer from the external environment, thereby providing the heat storage body 300 with a stable high-temperature environment and extending the heat storage time of the heat storage body 300. The user then detachably connects the other end of the heat storage body 300 to the lid 200.

[0026] At this time, the insulated cup set is in a portable state, and the heat storage body 300 maintains a high temperature with the insulating protection of the outer cup 100. When the user needs to use the hot bag to apply a hot compress, they only need to operate the connection between the lid 200 and the outer cup 100, for example, by rotating or pressing to remove the lid 200 from the outer cup 100. Because the heat storage body 300 and the lid 200 are detachably connected, the heat storage body 300 can be removed together with the lid 200, or the heat storage body 300 can be easily exposed after the lid 200 has been removed, and the user can easily separate it from the lid 200 and use it.

[0027] Throughout the entire process, the user does not need to directly touch the hot heat storage body 300, nor does they need to search for the external cup 100, significantly improving ease of use.

[0028] One practical application is that if a user needs to drink something cold or hot outdoors, they can manually remove the heat storage unit 300 to free up the space it occupies, thereby increasing the volume of the external cup 100. The user then pours the cold or hot beverage into the external cup 100.

[0029] Because the outer cup 100 has an insulating intermediate layer, it can effectively block heat transfer from the external environment, thereby providing the heat storage body 300 with a stable high-temperature environment and extending the time that beverages are kept warm.

[0030] When a user needs to drink something, they only need to operate the connection between the lid 200 and the outer cup 100. For example, by rotating or pressing, they can remove the lid 200 from the outer cup 100 and drink hot or cold beverages.

[0031] In some embodiments, referring to Figures 1 to 3, a locking assembly 400 is installed between the lid 200 and the outer cup 100, and the locking assembly 400 can connect the lid 200 and the outer cup 100 by mechanical engagement.

[0032] In the specific implementation process, the locking assembly 400 engages the lid 200 and the outer cup 100, firmly connecting them and making them difficult to separate during normal use and carrying. This is achieved by physical locking of locking claws or projections on the locking assembly 400 with corresponding structures on the outer cup 100 (e.g., locking grooves 430, edges). Alternatively, the elastic deformation of the locking assembly 400 can generate a biasing force when the lid 200 and the outer cup 100 are joined, thereby achieving a tight fit.

[0033] When assembling the lid 200 and the outer cup 100, the engaging assembly 400 cooperates with the corresponding structure in the outer cup 100 to generate a biasing force through physical locking or elastic deformation, thereby firmly fixing the lid 200 to the outer cup 100. This engaging connection method significantly improves the strength of the connection between the lid 200 and the outer cup 100 compared to a simple detachable connection, effectively preventing the lid 200 from falling off due to accidental impact or shaking during carrying or use, and further ensuring the airtightness of the insulated cup set and the stability of the internal heat storage body 300.

[0034] In some embodiments, referring to Figures 4 to 6, the engaging assembly 400 includes a pressing body 410 positioned along the axial direction of the lid 200 and an expandable body 420 positioned along the radial direction of the lid 200. The pressing body 410 and the expandable body 420 slide and engage with the lid 200, and the pressing body 410 and the expandable body 420 cooperate with each other to form an interlocking mechanism, converting the axial movement of the pressing body 410 into the radial movement of the expandable body 420, thereby achieving an engaged connection between the lid 200 and the outer cup 100.

[0035] In the specific implementation process, the pressing body 410 is a member that receives and transmits an external operating force, and is installed along the axial direction of the lid 200, with the main direction of movement or operation of the pressing body 410 being parallel to the central axis of the lid 200. The telescopic body 420 is a member that can expand and contract in its longitudinal direction or move radially, and is installed along the radial direction of the lid 200, with the main direction of movement of the telescopic body 420 being perpendicular to the central axis of the lid 200, i.e., it expands and contracts outward or inward, and is used to achieve engagement or disengagement with the external cup 100. The pressing body 410 can drive the telescopic body 420 to expand and contract relative to the lid 200, and can convert the axial movement of the pressing body 410 into the radial movement of the telescopic body 420, thereby achieving engagement with the external cup 100.

[0036] When the user operates the pressing body 410, the pressing body 410 moves along the axial direction of the lid 200, and this axial motion is converted into radial motion of the expandable body 420 by an internal mechanical conversion structure (e.g., the action between the inclined surface on the pressing body 410 and the engaging surface on the expandable body 420). When the expandable body 420 extends radially, it can reliably engage with the corresponding engaging structure on the outer cup 100 (e.g., the locking groove 430), thereby firmly fixing the lid 200 to the outer cup 100. Conversely, when the pressing body 410 is driven to contract the expandable body 420 radially, the engagement with the outer cup 100 is released, and the lid 200 can be easily separated from the outer cup 100.

[0037] Furthermore, the pressing body 410 and the telescopic body 420 allow the user to unlock the lid 200 with one hand, thereby providing convenience for the user's daily use.

[0038] In some embodiments, referring to Figures 4 to 6, the locking assembly 400 includes a locking groove 430 installed in the outer cup 100, the locking groove 430 fits into the telescopic body 420, and the locking groove 430 can provide a clear and secure engagement point to the telescopic body 420, making the engagement connection between the lid 200 and the outer cup 100 stronger and more secure, thereby preventing the lid 200 from loosening or falling off due to vibration or accidental touch during the use or carrying of the insulated cup set.

[0039] In the specific implementation process, the engagement groove 430 is a recessed structure or groove formed in the outer cup 100, and its main function is to provide a mating surface for insertion, engagement, or locking to the telescopic body 420. The engagement groove 430 can be designed as an annular groove, a plurality of discrete holes or recesses, or a concave region having a specific geometric shape. It can be formed by integral molding, machining, or attachment to the inner or outer wall of the outer cup 100. The shape, dimensions, and position of the engagement groove 430 and the telescopic body 420 match the shape, dimensions, and extension path of the telescopic body 420, so that the telescopic body 420 can smoothly enter the engagement groove 430 when driven by the pressing body 410 to form a stable mechanical connection.

[0040] In some embodiments, referring to Figure 6, the pressing body 410 is provided with a tapered surface that fits the expandable body 420. The conformal fitting of the tapered surface on the pressing body 410 and the expandable body 420 effectively decomposes the axial thrust of the pressing body 410 into a dividing force that drives the radial motion of the expandable body 420, providing a gradual guiding action, thereby ensuring the accuracy and smoothness of the motion trajectory during the expansion and contraction process of the expandable body 420 and avoiding the occurrence of degeneration phenomena.

[0041] In the specific implementation process, the pressing body 410 is a component that receives an external operating force and transmits it to the telescopic body 420, and it may be in the form of a button, push rod, or knob. The telescopic body 420 is an important component that enables engagement with or disengagement of the engagement groove 430 in the external cup 100, and it may be in the form of a pin, bump, or engagement tongue. The tapered surface is an inclined surface structure that gradually narrows or widens, and it may be a perfect cone surface or a partial tapered surface, for example, a sloping guide surface. Fit means that the tapered surface of the pressing body 410 and the telescopic body 420 match each other in shape, dimensions, and function to achieve a desired fitting effect, for example, by matching the angle of the tapered surface with the angle of the corresponding contact surface in the telescopic body 420, or by fitting with a groove or projection in the telescopic body 420 due to the shape of the tapered surface.

[0042] When the pressing body 410 is pressed, the tapered surface gradually pushes the expandable body 420, causing it to move radially outward and extend, engaging with the engagement groove 430 in the outer cup 100. Conversely, when the pressing body 410 is released or rebounds, the tapered surface guides the expandable body 420 to contract radially inward, disengaging it from the engagement groove 430.

[0043] In some embodiments, referring to Figures 3 and 5, a connecting assembly 500 is further installed between the outer cup 100 and the lid 200. The connecting assembly 500 is a mechanism that enables a tight connection between the members and maintains mechanical locking and good sealing. The connecting assembly 500 includes one threaded body 510, which is integrally connected to the lid 200. The threaded body 510 is integrally formed with the lid 200, thereby simplifying the structure and improving the reliability of the connection. The outside of the threaded body 510 is screwed into the outer cup 100, and the male threads on the threaded body 510 mesh with the corresponding female threads on the outer cup 100, enabling rotation and thus achieving fastening.

[0044] In the specific implementation process, the top edge of the outer cup 100 is set up as an opening with female threads, while the bottom of the lid 200 extends inward to form a cylindrical threaded body 510. Male threads are machined into the outer wall of the threaded body 510 to match the female threads of the opening of the outer cup 100.

[0045] When it is necessary to seal the set of insulated cups, the user places the lid 200 on top of the outer cup 100 and rotates the lid 200 clockwise. At this time, the male threads of the screw body 510 gradually engage with the female threads of the outer cup 100 and are tightened securely until the lid 200 is in close contact with the outer cup 100, forming a strong and sealed connection.

[0046] In some embodiments, referring to Figure 3, the ends of the heat storage body 300 and the threaded body 510 are connected by screws or locking parts, and the heat storage body 300 is firmly fixed to the threaded body 510 by designing the structure so that the ends of the heat storage body 300 and the threaded body 510 are screwable or connected by locking parts.

[0047] When a screw connection is used, the heat storage body 300 tightly connects with the screw body 510 by rotation, forming a secure mechanical fixation and ensuring the airtightness of the connection. When a locking connection is used, the heat storage body 300 is quickly locked into the screw body 510 by pushing and / or rotating, enabling convenient installation and removal.

[0048] The connection method between the heat storage body 300 and the screw body 510 involves the screw body 510 being screwed into the outer cup 100, providing a clear and secure fixing point to the heat storage body 300, ensuring stability within the heat storage body 300 set, and providing great convenience for the user in daily maintenance and replacement operations of the heat storage body 300.

[0049] In some embodiments, the heat storage body 300 is a rubber rod or a resin rod having a predetermined shape and material, which can significantly improve the structural integrity and durability of the heat storage body 300.

[0050] The rod-shaped heat storage body 300 is stably inserted into the outer cup 100 and can be detachably connected to the lid 200, thus avoiding deformation, displacement, or leakage problems that may occur in conventional soft ice bags.

[0051] By selecting rubber or resin material, the heat storage body 300 itself is endowed with excellent impact and abrasion resistance, thereby ensuring the safe packaging of the refrigerant and extending the product's service life. The robust heat storage body 300 works in conjunction with the outer cup 100, which has an insulating intermediate layer, and the detachably connected lid 200 to form a more reliable, efficient, and portable insulated cup set. This effectively solves the problem of conventional ice bags being easily damaged and leaking during use, and ensures a sustained and stable cooling effect.

[0052] In some embodiments, referring to Figure 5, an annular gap for accommodating a refrigerant is formed between the heat storage body 300 and the inner wall of the outer cup 100, and the heat storage body 300 and the inner wall of the outer cup 100 maintain a certain distance from each other, thereby forming an annular passage. The annular gap is designed to accommodate the refrigerant. The refrigerant can be any substance that provides a cooling effect, such as water, ice, cooling gel, phase change material, or pre-cooled liquid. By creating a gap between the heat storage body 300 and the inner wall of the outer cup 100 and filling it with refrigerant, the total volume of the cooling medium and the contact area with the object to be cooled can be effectively increased.

[0053] When the heat storage body 300 is inserted into the outer cup 100, it itself provides an initial cooling effect as the primary cooling source. Furthermore, the installation of an annular gap allows the user or manufacturer to inject an additional refrigerant between the heat storage body 300 and the inner wall of the outer cup 100. This refrigerant cools itself by exchanging heat with the heat storage body 300 and, by directly contacting the inner wall of the outer cup 100, can efficiently transfer coolness to the items inside the outer cup 100. The cooperation of such dual cooling sources (heat storage body 300 and refrigerant in the annular gap) not only increases the total volume of the cooling medium but also increases the effective surface area for heat exchange, ensuring that coolness is transferred more uniformly and sustainably.

[0054] The above descriptions are merely preferred specific embodiments of the present invention, and the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are easily conceivable to a person skilled in the art within the technical scope disclosed herein should be included within the scope of the present invention.
