Technical Field

[0003] The present description relates to systems, devices or apparatus for cryogenic storage, transport and / or transportation of liquids or gases below ambient temperature. Background Art

[0004] Laboratory technicians, scientists, medical professionals such as doctors or nurses, and other technicians can utilize liquids or gases for temperature control to store and transport goods at low temperatures to various facilities, such as hospitals, laboratories, and / or research facilities. During the transportation of goods, the goods are kept at cryogenic temperatures. In addition, technicians and / or professionals store goods in Dewar flasks, which are used to keep goods at refrigerated or cryogenic temperatures. Dewar flasks can take several different forms, including open barrels, bottles, and / or self-pressurized tanks. Dewar flasks can be double-walled metal or glass bottles with vacuum between the walls. This provides thermal insulation between the walls.

[0005] A technician or professional may fill the Dewar's flask with merchandise and liquid or gas and pack the Dewar's flask with shipping materials. The technician or professional then provides the package including the Dewar's flask to a shipper to transport the contents to the final destination where they are unpacked. However, liquids or gases boil slowly, so the Dewar's flask may have an opening on the top that is designed to allow the gas to escape. In addition, while in transport, the Dewar's flask may tilt or flip, which may cause the liquid or gas to flow out of the Dewar's flask.

[0006] Therefore, a system, device or apparatus is needed to protect the liquid or gas in the Dewar flask from evaporation and pouring out during transportation. Summary of the invention

[0031] Disclosed herein are systems, devices, and apparatus for transporting and storing liquids or gases such as liquid nitrogen. The system, device, or apparatus may be a cryogenic storage system for storing and transporting liquids. Specific embodiments of the subject matter described in this specification may be implemented to achieve one or more of the following advantages.

[0032] The cryogenic storage system may have a capsule made of a polymer material so that the capsule can withstand cryogenic temperatures. That is, the polymer material is brittle and not easily broken at cryogenic temperatures. The capsule may hold or suspend a dewar flask containing a liquid or gas. In addition, the capsule surrounds the dewar flask to protect the dewar flask from any impact. The capsule may freely suspend or hold the dewar flask so that the dewar flask rotates and / or moves freely in the capsule without impacting the inner side of the capsule. In addition, the dewar flask may be spherical and have passive stability. That is, the dewar flask may have a center of mass positioned directly opposite to the opening and a center of gravity at or near the bottom of the dewar flask near the center of mass so that the dewar flask remains in an upright or vertical position or returns to an upright or vertical position when tilted. Since the dewar flask is able to rotate freely in the capsule and has passive stability, the dewar flask remains upright regardless of the orientation of the capsule to prevent overflow. In addition, by making the dewar flask upright and stable, the cryogenic storage system reduces the evaporation of the liquid in the dewar flask. For example, the cryogenic storage system reduces the rate of nitrogen evaporation within the dewar, which extends the life of the dewar in transit.

[0033] Other benefits and advantages include: the capsule has multiple faces that provide access to the dewar, which improves physical access to the opening of the dewar for inserting and / or removing liquids or gases. In addition, the dewar can have electronics to transmit and monitor the temperature inside the dewar, and have a connection device that reduces the amount of friction between the capsule and the dewar when the dewar is free to rotate.

[0034] Figure 1 shows a perspective view of a cryogenic storage system 100 according to various embodiments, and Figure 2A cross-sectional view of a cryogenic storage system 100 is shown. Cryogenic storage system ("storage system") 100 includes a capsule 102, a dewar 104, such as a double-walled bottle, and a vapor plug 106. Capsule 102 is three-dimensional (3D) and may be shaped as a cube. Capsule 102 may be shaped as any type of three-dimensional object, such as a cube, tetrahedron, dodecahedron, or octahedron, and may be made of a polymer material so that capsule 102 does not break at cryogenic temperatures.

[0035] The capsule 102 has a plurality of side portions 108 or faces. The side portions 108 form a closed capsule around or encloses the dewar flask 104. The side portions 108 may be a planar or grid-like surface connected to other side portions to form the capsule 102 and around the dewar flask 104. The dewar flask 104 is inserted or placed into the cavity of the capsule 102 so that the dewar flask 104 resides in the capsule 102. A plurality of side portions 108 may be snapped together using one or more fasteners. For example, a plurality of side portions 108 may be snapped together at one or more corners 112. In some embodiments, the capsule may be formed by a plurality of modular pieces. A plurality of modular pieces may be connected and / or fastened together to form the capsule 102. A plurality of side portions may have one or more capsule openings 110. One or more capsule openings 110 may be circular and / or shaped to be the same shape as the dewar flask opening. As the dewar 104 rotates within the capsule 102, one or more capsule openings 110 provide access to the dewar 104. Thus, regardless of the orientation of the capsule 102, the openings 402 of the dewar 104 are accessible.

[0036] For example, the capsule 102 is shaped as a cube and has six sides 108. Each side is connected to at least one other side at a corner 112. On each side, there is a capsule opening 110. When the Dewar opening is aligned with the capsule opening 110 on the side of the capsule 102, the capsule opening allows access to the vapor plug 106 and the Dewar opening. Therefore, as the Dewar rotates within the cavity of the capsule, when one or more of the capsule openings 110 are aligned with the Dewar opening, one or more of the capsule openings 110 provide access to the vapor plug 106 and the Dewar opening.

[0037] The enclosure 102 may have an inner frame 114 and an outer frame 116. The outer frame 116 protects the dewar 104 from bumps, vibrations, and / or shocks. For example, when the enclosure 102 is transported or stored, the outer frame 116 separates the dewar 104 from other objects such as other boxes or the side of a truck. The inner frame 114 forms a cavity within the enclosure 102 in which the dewar 104 is located. The dewar 104 may be hung, placed, or otherwise located within the cavity of the inner frame 114 so that the dewar 104 can rotate within the cavity.

[0038] The storage system 100 may include a ball transfer device 900 connected between the capsule 102 and the dewar 104. The ball transfer device 900 facilitates movement of the dewar relative to the capsule 102. The ball transfer device 900 may be positioned at the inner phalanges or wings 202 between the capsule 102 and the dewar and provide a frictionless or nearly frictionless surface. The ball transfer device 900 minimizes or eliminates friction between the dewar and the capsule 102, which allows the dewar to move or rotate freely within the capsule 102. Fig. 9 The structure of the ball transfer device 900 is further described.

[0039] The storage system 100 includes a dewar 104. The dewar 104 may be a double-walled flask and may be shaped as a sphere or any other polyhedron. The dewar 104 may be centrally located within the central cavity of the enclosure 102 and may be free to rotate and / or move within the central cavity. The dewar 104 may rotate about a central vertical axis 306 in directions 302, 304 or in any other direction in three dimensions, such as Figure 3 shown.

[0040] The dewar 104 has an inner wall 504, an outer wall 502, and an opening 402. The storage system 100 may have a plug, such as a vapor plug 106, that may be inserted into the opening 402 to seal or partially seal the dewar 104 while allowing some gas to escape, such as Figure 4 The opening 402 leads to a cavity or payload area 506 within the dewar 104 . Figure 5 The payload area 506 is shown in a cross-sectional view of the dewar 104. The dewar 104 can create a vacuum between the inner wall 504 and the outer wall 502 to hold or store liquids or gases below ambient temperature. The dewar 104 can have a pump-out port 412. The pump-out port 412 can be used to create a vacuum between the inner wall 504 and the outer wall 502 of the dewar 104, which allows the space between the inner wall 504 and the outer wall 502 to be completely evacuated.

[0041] The dewar 104 has an inner wall 504 and an outer wall 502 with a vacuum between the inner wall 504 and the outer wall 502. The outer wall 502 has an opening 402 that allows liquid or gas to be inserted or placed into the payload area 506. The opening 402 can be positioned opposite the center of gravity or mass 512 of the dewar 104 so that the opening 402 remains upright when the dewar 104 is passively stabilized. The opening 402 allows gas to escape from the payload area 506 of the dewar 104 to relieve gas expansion within the dewar 104.

[0042] The inner wall 504 forms and / or encloses a payload area 506 within the dewar 104. The payload area 506 can be a cylindrical cavity within the dewar 104 that extends longitudinally from a top portion 508 of the dewar 104 to a bottom portion 510 thereof. The payload area 506 holds or stores liquids or gases that are below ambient temperature. An absorbent material 606 can be at or around a bottom portion of the payload area 506. The absorbent material 606 can maintain a temperature within the payload area 506 below ambient temperature.

[0043] The dewar 104 has a top portion 508 and a bottom portion 510. The top portion 508 is where the opening 402 is located and is held upright due to the passive stability of the dewar 104. The bottom portion 510 includes a center of gravity or mass 512. Because the center of gravity or mass 512 is located within the bottom portion 510 of the dewar 104, the dewar 104 is stabilized about the center of gravity or mass 512 so that the dewar 104 remains upright. By stabilizing the dewar 104 about the center of gravity or mass 512, regardless of the orientation of the enclosure 102, the storage system 100 reduces the amount and / or rate of evaporation of the liquid or gas and / or absorbent material, for example, the nitrogen evaporation rate is reduced. The amount and / or rate of evaporation of the liquid or gas and / or absorbent material is based on the size of the cross-sectional surface area 604a-c of the liquid or gas 602, for example, as Figures 6A-6C Additionally, due to the passive stability of the dewar 104, the dewar 104 increases the amount of shipping density within the shipping container because the dewar 104 can be enclosed in any shape enclosure 102, which allows the shipper to use any shape for the enclosure 102 that best fits the available space or void volume within the shipping container.

[0044] Fig. 6A 1 shows liquid or gas 602 and absorbent material 606 within the payload area 506 of the dewar 104 when the dewar 104 is upright. The absorbent material 606 may be positioned within or around a bottom portion of the payload area 506 of the dewar 104. When the dewar 104 is upright, the cross-sectional surface area 604a of the liquid or gas 602 has a diameter D because the payload area 506 is upright or vertical. If the payload area 506 is angled or tilted, such as Figure 6B and 6CAs shown, the liquid or gas 602 will have a cross-sectional surface area 604b-c of D+ΔD, respectively, which is greater than the cross-sectional surface area 602a, D when the payload area 506 is upright or vertical. As the payload area 506 is tilted or angled, the shape of the cross-sectional surface area 604a transitions from a circular shape to an elliptical shape of the cross-sectional surface areas 604b-c due to the cylindrical nature of the payload area 506. The size of the elliptical cross-sectional surface areas 604b-c increases as the angle increases. The increased cross-sectional surface areas 602b-c result in an increased evaporation rate and / or evaporation amount of the liquid or gas 602, and / or an increased consumption rate or consumption of the absorbent material 606. The increased cross-sectional surface areas 604b-c expose more of the liquid or gas 602 to the higher temperature medium, thereby resulting in a faster consumption rate of the absorbent material 606 to cool the liquid or gas 602. Additionally, as the payload area 506 tilts, liquid and / or gas may overflow or escape from the opening 402 of the dewar 104. Additionally, as the liquid or gas 602 overflows and / or the cross-sectional surface area 602b-c increases, a partial vacuum is created, which draws in hot air that further increases the average temperature and results in a faster consumption rate of the absorbent material 606 to cool the liquid or gas 602.

[0045] Because the Dewar 104 within the storage system 100 has passive stability that maintains the Dewar 104 in an upright position regardless of the orientation of the enclosure 102, the payload area 506 within the Dewar 104 remains in an upright position or returns to an upright position when the Dewar 104 is tilted, rotated, and / or otherwise angled. Therefore, the storage system 100 reduces the amount and / or rate of evaporation of the liquid or gas 602 and reduces the rate of consumption of the absorbent material 606 by maintaining the Dewar 104 in an upright position and / or passively adjusting the Dewar 104 so that the Dewar 104 returns to or remains in an upright and / or vertical position. In addition, by reducing the rate of consumption of the absorbent material 606, which may be nitrogen, the dynamic retention time of the Dewar 104 is increased. The dynamic retention time is the time that the Dewar 104 maintains the internal temperature at or below -150°C during transportation.

[0046] Storage system 100 includes a vapor lock 106 . Figure 4 and Figure 7The vapor plug 106 is shown. The vapor plug 106 can have a handle portion 408 and a neck 410. The handle portion 408 can have a handle or grip that allows a user to twist the vapor plug 106 in a clockwise or counterclockwise direction to insert at least a portion of the neck 410 into the opening 402. The vapor plug 106 can be removable. That is, the vapor plug 106 can be inserted into the opening 402 of the dewar 104 to close or partially close the dewar 104 and prevent access to the payload area 506. The handle portion 408 and / or the neck 410 can be made of a non-conductive material, such as a polymer or a fiberglass material.

[0047] For example Figure 4 As shown, the vapor plug 106 can be rotated or twisted clockwise and / or counterclockwise. For example, the vapor plug 106 can be rotated clockwise when inserted into the opening 402 to secure the vapor plug 106 within the opening 402, and rotated counterclockwise to remove the vapor plug 106 from the opening 402 to allow liquid or gas to be inserted into the payload area 506. In another example, the vapor plug 106 can be rotated counterclockwise when inserted into the opening 402 to secure the vapor plug 106 within the opening 402, and rotated clockwise to remove the vapor plug 106 from the opening 402. The vapor plug 106 can be inserted into the opening 402 so that there is a gap to allow gas to escape to prevent pressure from accumulating as liquid within the payload area 506 evaporates.

[0048] The vapor plug 106 may have a locking device 704, such as Figure 7 506 of the Dewar 104. The locking device 704 may be positioned on the neck of the vapor plug 106. The locking device 704 may be one or more magnets that interlock with one or more other magnets within the top interior portion of the payload area 506 of the Dewar 104. The magnets may have opposite polarities so that when the vapor plug 106 is rotated in a particular position within the Dewar 104, the magnets lock the vapor plug within the Dewar 104. Conversely, when the vapor plug 106 is rotated about its axis to another position, the opposite polarity of the magnets may force the vapor plug to leave the Dewar 104.

[0049] When the vapor plug 106 is inserted into the payload area 506, the locking device 704 locks. Since there may be a gap between the vapor plug 106 and the interior portion of the payload area 506 of the dewar 104, the locking device 704 locks the vapor plug 106 and the dewar 104 in place to prevent the vapor plug 106 from falling out when the dewar 104 is oriented or rotated in different directions. The gap between the vapor plug 106 and the dewar 104 allows gas to escape due to evaporation of liquid or expansion of gas in the payload area 506 to prevent pressure from accumulating in the payload area 506.

[0050] The storage system 100 may include an electronic thermocouple 702, which may be positioned, embedded or included in the neck 410 of the vapor plug 106, or connected to the neck 410 of the vapor plug 106. The electronic thermocouple 702 may be an electronic device or sensor that measures and monitors the temperature within the dewar 104. The electronic thermocouple 702 may use a wireless protocol to wirelessly transmit and / or communicate with another electronic device such as a smart data logger. The electronic thermocouple 702 may communicate with the smart data logger and provide the temperature, and / or may receive instructions from the smart data logger to monitor the temperature. The smart data logger may display the temperature to a user or another electronic platform or otherwise communicate the temperature. This allows real-time monitoring of the temperature within the dewar 104 by other individuals.

[0051] The storage system 100 may include an electronic orientation sensor 706, which may be positioned, embedded or included in the neck 410 of the vapor plug 106, or connected to the neck 410 of the vapor plug 106. The electronic orientation sensor 706 may be an electronic device or sensor that measures the orientation within the dewar 104, such as a gyroscope or the like. The electronic orientation sensor 706 may use a wireless protocol to wirelessly transmit and / or communicate with another electronic device such as a smart data logger. The electronic orientation sensor 706 may communicate with the smart data logger and provide it with orientation data and / or angular velocity data, and / or may receive instructions from the smart data logger to monitor orientation. The smart data logger may display the orientation to a user or another electronic platform or otherwise communicate the orientation. This allows other individuals to monitor the orientation of the dewar 104 in real time.

[0052] The storage system 100 may include a corrugated neck tube 800, such as Figures 8A-8B As shown. The corrugated neck tube 800 can be thin-walled. The corrugated neck tube 800 connects the outer wall 502 of the Dewar flask 104 to the inner wall 504. The corrugated neck tube 800 reduces the overall height of the neck tube, but keeps the overall path length for conducting heat the same as a straight neck tube. The corrugated neck tube 800 may have a serpentine path 802 that provides heat conduction. By reducing the height of the neck tube, but keeping the overall path length the same as a straight neck tube, the corrugated neck tube 800 reduces the overall size of the Dewar flask 104. In addition, by keeping the overall path length for conducting heat the same as a straight neck tube, the corrugated neck tube 800 reduces the heat conducted into the Dewar flask 104. Therefore, the corrugated neck tube 800 provides the same heat conduction with a shorter neck tube (e.g., shorter overall height or size) than a straight neck tube of similar overall path length. For example, the height of the corrugated neck tube 800 may be 2-3 inches long, while the overall path length for heat conduction may be 6 inches long because the overall path length for heat conduction may be a serpentine path along the thin wall corrugated neck tube.

[0053] For example Fig. 9As shown, the storage system 100 includes a ball transfer device 900. The ball transfer device 900 can be connected to the capsule 102 at the inner phalanx or wing 202. The ball transfer device 900 can provide an interface between the capsule 102 and the dewar 104 and allow the dewar 104 to rotate freely within the cavity of the capsule 102.

[0054] The ball transfer device 900 can have a head 902 and a body 904. The head 902 and the body 904 can be shaped as cylinders. The diameter of the head 902 can be greater than the diameter of the body 904. The ball transfer device 900 can be inserted into a hole or opening of the inner phalanx or wing 202. For example, the body 904 can be inserted into the opening and the head 902 can form a seal around the opening of the inner phalanx or wing 202. The head 902 and the body 904 can have an opening and a cavity in which the ball bearing 906 and the spring 908 reside.

[0055] The ball transfer device 900 may have a ball bearing 906, a cup 910, and a spring 908, which is seated or resting in the cavity of the ball transfer device 900. The ball bearing 906 may have a top portion and a bottom portion. The top portion of the ball bearing 906 may protrude from the head 902 of the ball transfer device 900. When the dewar 104 is seated in the cavity of the capsule 102, the protruding top portion of the ball bearing 906 contacts the dewar 104. The ball bearing 906 minimizes the friction between the capsule 102 and the dewar 104, thereby allowing the dewar 104 to rotate or move freely within the capsule 102. The ball bearing 906 provides a frictionless surface or a reduced friction surface. The bottom portion of the ball bearing 906 in the cavity of the body 904 may rest on the cup 910, which engages the spring 908.

[0056] The cup 910 interfaces between the bottom portion of the ball bearing 906 and the spring 908, so that when a force is applied to the top portion of the ball bearing 906, the bottom portion of the ball bearing 906 presses against the cup 910, which provides a downward force on the spring 908, causing the spring 908 to contract. This allows the dewar 104 to rotate freely within the capsule 102 and allows the capsule 102 to absorb shock and vibration during storage and / or transportation. When the dewar 104 presses against the ball bearing 906, the ball bearing 906 further enters the cavity of the body 904 while the spring 908 further contracts. This allows the dewar 104 to push rather than remain rigid, thereby absorbing any shock or vibration. When the event that caused the shock or vibration has passed, the spring 908 returns or expands back to a normal state and keeps the dewar 104 positioned in the cavity of the capsule 102. Additionally, one or more ball bearings 906 allow the dewar 104 to be rotated or angled so that the dewar 104 remains passively stable and upright regardless of the orientation of the enclosure 102 .

[0057] The spring 908 may contract when a downward force is applied to the ball bearing 906, such as when the dewar 104 exerts an outward force on the ball bearing 906 due to an impact or vibration on the capsule 102. For example, when the capsule 102 moves, shifts, or drops, a vibration force is exerted on the capsule 102. If the dewar 104 moves or shifts in response to the vibration force, the dewar 104 may exert an outward force on the ball transfer device 900, but instead of violently contacting the capsule 102, the dewar 104 exerts a force on the ball bearing 906, which retracts within the cavity of the body 904 and causes the spring 908 to contract and absorb the force.

[0058] Reference now Fig.10 , shows a storage system 1000 according to various embodiments. The storage system 1000 includes a dewar 104 and a capsule assembly 1002. The capsule assembly 1002 includes a first support ring 1010 and a second support ring 1020. The first support ring 1010 can be arranged opposite to the second support ring 1020. The first support ring 1010 and the second support ring 1020 can include the same geometric shape (e.g., a track, etc.).
