Aspects of this disclosure relate to an insulating container.
In the exemplary implementation, the insulated container 100 may comprise a double wall construction that may be a vacuum-insulated double wall structure with the outer shell 110 connected to the inner shell 140. The double wall construction may form a sealed vacuum cavity 120 between the outer shell 110 and the inner shell 140 as shown in
The container 100 may be sized to contain oversized items and may function as an insulated bucket or container. For instance, the container 100 may hold a volume greater 1800 cubic centimeters. In some examples, the container 100 may hold a volume within a range of 1900 cubic centimeters and 3000 cubic centimeters, or within a range of 1800 cubic centimeters and 4000 cubic centimeters, or greater even greater than 4000 cubic centimeters. In the illustrated example, the top opening 104 may have a width, W, or diameter within a range of 240 mm and 250 mm, or within a range of 230 mm and 260 mm, where the width, W, is defined as a horizontal distance across the widest part of the storage cavity 150. In addition, the storage cavity 150 of the container 100 may have a height greater than 160 mm, or within a range of 160 mm and 240 mm, or within a range of 180 mm and 220 mm, where the height, H, is defined a vertical distance between the upper end 106 of the top opening 104 and inner bottom wall 146. The width, W, may be greater than the height, H. In addition, the width and height may be expressed as a ratio to each other. For instance, the ratio of the width, W, of the top opening 104 to the height, H, of the storage cavity may be approximately 1.23:1, or within a range of 1.31:1 and 1.14:1, or within a range of 1.44:1 and 1.1:1. In examples that may have a different shape than the illustrated example, such as a rectangular cuboid, the container 100 may have exterior dimensions of a height within a range of 300 mm and 400 mm, a length within a range of 430 mm and 530 mm, and a width within a range of 300 mm and 400 mm as well as an internal volume within a range of 1800 cubic centimeters and 4000 cubic centimeters.
As shown in
A foot bracket 170 may be located in the lower ring-shaped cavity 130. The foot bracket 170 may be connected to the bottom cavity wall 136 and may include a hook member or a plurality of hook members 172 that engage and secure the elastomeric foot member 190. The foot member 190 may be ring-shaped and form a slip resistant surface to support the container 100. In addition, a plurality of openings 138 may be located along the bottom cavity wall 136. The openings 138 may be round shaped holes and may be evenly spaced around the lower ring-shaped cavity 130. In the illustrated example, the plurality of openings 138 comprises three openings, but the number of openings may be two openings, four openings, or more than four openings. As discussed below, the openings 138 may assist in evacuating the gas from the cavity formed between the outer and inner shells 110, 140. In addition, the holes 138 may be aligned with similar openings 174 arranged along a bottom surface of the foot bracket 170.
The support member 160 may be formed from an insulating material while also being compressible. The support member 160 may be a foam, a lattice structure, a honeycomb structure, or other solid insulating structure. In some examples, the support member 160 may also include or be formed from a heat resistant material. As discussed in more detail below when the container 100 is subjected to a vacuum during construction, the container 100 (and its components) may also be subjected high temperatures (i.e. greater than 200° C.), which may make some polymeric or fiber glass insulation materials unsuitable for use in the support member 160. As such, the support member 160 may be also heat resistant such as a heat resistant ceramic fiber insulation, an aerogel material, a ceramic fiber mat, or similar heat resistant insulation material. in addition, the support member 160 may be formed from, a ceramic material, a mineral wool material, a ceramic foam, an aerogel-based material (e.g. an aerogel blanket, an aerogel block, or similar aerogel structure), an organic material, or other high-temperature fiber-reinforced material. The support member 160 may also have a degree of porosity to help provide compressibility as wells as the desired insulating properties. For example, the support member 160 may have a porosity of greater than 60 percent, or greater than 80 percent, or even greater than 90 percent. Alternatively, the support member 160 may be incompressible, such as a fiber mat or blanket, or may be loose granules or particles that are located between the outer bottom wall 112 and the inner bottom wall 146.
The support member 160 may comprise an insulating material with a low thermal conductivity. The low thermal conductivity prevents a direct conduction pathway between the inner shell 110 and the outer shell 140. By preventing or reducing any direct conduction pathways between the shells 110, 140, the support member 160 along with the sealed vacuum cavity 120 may help to reduce or eliminate condensation due to the lack of a conduction pathway between the walls 102, 112, 142, 146 of the shells 110, 140. For example, the support member 160 may have a thermal conductivity within a range of 0.013 W/(m*K) and 0.040 W/(m*K).
In some examples, additional support members 160 may be located in different regions of the vacuum cavity 120 to help prevent or reduce deformation of one or more surfaces of the insulating container 100.
Next, the foot bracket 170 may be formed and connected to the outer shell 110 (220). The foot bracket 170 may include one or more hook members 172 that are attached to the bottom cavity wall 136 of the lower cavity 130. Similar to the outer and inner shells 110, 140, the foot bracket 170 may be formed from stainless steel and may be formed from a sheet metal forming process or alternatively, the foot bracket 170 may be formed via casting, forging, or molding. The foot bracket 170 may then be integrally joined to the outer shell 110 within the lower cavity 130.
In the next steps, the support member 160 may be secured between the inner shell 140 and the outer shell 110. First, the support member 160 may be placed onto an interior surface of the outer bottom wall 146 adjacent to the inner cavity wall 132 of the outer shell 110 (230). Next, the inner shell 140 may be placed into the opening 117 of the outer shell 110 until the outer surface of the inner bottom wall 112 contacts an upper surface of the support member 160 (240). In the next step, the inner shell 140 may be pressed until the upper edge 148 of the inner shell 140 aligns with an upper edge 118 of the outer shell 110. During this process, the support member 160 is compressed from an uncompressed state until the compressed state (250).
Once the support member 160 is compressed and the upper edges 118, 148 of the outer and inner shells 110, 140 are aligned, the inner shell 140 may be integrally joined to the outer shell 110 by one or more coupling processes along the upper edges 118, 148 of the outer shell 110 and the inner shell 140 (260). In one specific example, the inner shell 140 may be secured to the outer shell 110 by a welding operation utilizing a robotic arm and camera system in conjunction with a stationary electrode or the like to ensure that inner shell 140 is connected along the entire upper edges 118, 148 of the outer shell 110 and the inner shell 140. These coupling processes may integrally join the outer shell 110 and the inner shell 140 and may include one or more brazing or welding processes (including, among others, shielded metal arc, gas tungsten arc, gas metal arc, flux-cored arc, submerged arc, electroslag, ultrasonic, cold pressure, electromagnetic pulse, laser beam, or friction welding processes). In another example, the outer shell 110 may be integrally joined to the inner shell 140 by one or more adhesives, by a sheet metal hem joint, or by one or more fastener elements (e.g. one or more screws, rivets, pins, bolts, or staples, among others).
Once the shells 110, 140 are integrally joined and secure the support member 160, a mass of gas/air may be evacuated from the cavity formed between the inner and outer shells 140, 110 to create a sealed vacuum cavity 120 between the two shells 110, 140 (270). To achieve a vacuum between the walls of the container 100 (e.g. between the outer sidewall 102 and the inner sidewall 142, and the outer bottom outer wall 112 and the inner bottom wall 146), at least a portion of air between the two shells 110, 140 may be removed by positioning the container 100 within a larger chamber (not depicted), and removing at least a portion of the air from the cavity 120 between the shells 110, 140 by pulling a vacuum within the larger chamber (not depicted) (e.g. reducing an internal pressure of the larger chamber to a pressure below an internal pressure within the vacuum cavity 120). It will be appreciated that any techniques and/or processes may be utilized to reduce a pressure within the larger chamber (not depicted), including, vacuum pumping, among others. As such, a portion of air within the vacuum cavity 120 may escape through a plurality of openings 138 located in the bottom cavity wall 136 of the lower cavity 130 located on the outer bottom wall 112. The openings 138 may be round shaped holes and may be evenly spaced around the lower ring-shaped cavity 130. In addition, the openings or holes 138 may be located in the bottom cavity wall 136 and also be aligned with holes 174 arranged in the foot member such that the vacuum may be applied after the foot member 190 is applied to the outer shell 110.
In certain implementations, a pressure within the vacuum cavity 120 of the insulating container 100 may measure less than 15 μTorr. In other examples, the vacuum may measure less than 10 μTorr, less than 50 μTorr, less than 100 μTorr, less than 200 μTorr, less than 400 μTorr, less than 500 μTorr, less than 1000 μTorr, less than 10 mTorr, less than 100 mTorr, or less than 1 Torr, among many others. The support member 160 may help prevent any deformation caused by a pressure differential between a pressure external to the insulating container 100 (i.e. atmospheric pressure), and an internal vacuum pressure within the vacuum cavity 120 and outside the container 100. The support member 160 may provide additional structural rigidity and support along the inner bottom wall 146 to prevent the walls from deforming and helping to keep the inner bottom wall 146 substantially planar.
In order to seal a vacuum within the vacuum cavity 120, a resin, which may be in the shape of a pill, may be placed into the openings 138 during the vacuum forming process (280). In some examples, the vacuum formation chamber may be heated to a temperature at which the resin may become viscous. In one example, the viscosity of the resin may be such that the resin does not flow or drip into the container through the opening, but is permeable to air such that the air can escapes the internal volumes of the vacuum cavity 120. In one implementation, a vacuum forming process may heat the insulating container 100 to temperature of approximately 550° C. In other implementations, during the vacuum forming process the insulating container may be heated to approximately 200° C., 250° C., 300° C., 350° C., 400° C., 450° C., 500° C., or 600° C., among others. Following a period of heating, the insulating container 100 may be passively or actively cooled to room temperature. As such, once the resin cools and solidifies, it covers the openings 138, and seals the internal volume of the container 100 to form a vacuum cavity 120 between the outer shell 110 and the inner shell 140.
Lastly, a foot member 190 may be installed onto the foot bracket 170 (290). The foot member 190 may be secured with a press fit or friction fit onto the hook members 172 of the foot bracket 170. The foot member 190 may be formed from an elastomeric material to help increase the friction and help prevent the container 100 from sliding when placed on a flat surface.
In the illustrated example of
In the exemplary implementation, the insulated container 300 may comprise a double wall construction that may be a vacuum-insulated double wall structure with the outer shell 310 connected to the inner shell 340. The double wall construction may form a sealed vacuum cavity 320 between the outer shell 310 and the inner shell 340. A portion of the sealed vacuum cavity 320 may include an insulating or support member 360. The support member 360 may comprise a single member or a plurality of structures. The support member 360 may be located between the outer bottom wall 312 of the outer shell 310 and the inner bottom wall 346 of the inner shell 340. The support member 360 may be secured between the outer bottom wall 312 and the inner bottom wall 346 with a friction fit due to the compression of the support member 360 during assembly. In some examples, the support member 360 may be secured to either or both of the outer bottom wall 312 and the inner bottom wall 346 using an adhesive. Additionally, the support member 360 may be secured in place by features that may be located on either or both of the outer bottom wall 312 and the inner bottom wall 346. These features may surround or partially surround the support member 360. The support member 360 may be one or more discrete structures arranged in an array, or a single structure that partially or fully fills a lower cavity 322 of the sealed vacuum cavity 320 that is formed between inner cavity wall 332 of the outer shell 310 and the inner shell 340.
The outer shell 310 may be approximately 1.0 mm and the inner shell 340 may be approximately 0.7 mm. The thickness of the outer shell 310 may also be approximately 0.5 mm, 0.75 mm, 1.25 mm, or 1.5 mm, or greater, without departing from the scope of the present disclosure. The thickness of the inner shell 340 may also be approximately 0.25 mm, 0.5 mm, 1.0 mm, 1.25 mm, or 1.5 mm, or greater, without departing from the scope of the present disclosure. Additionally, the thickness of the sealed vacuum cavity 320 may be approximately 3.45 mm and a minimum of at least 3.45 mm. The thickness of the sealed vacuum cavity 320 may also be approximately 3.5 mm, 3.75 mm, 4 mm, 5 mm, or greater, without departing from the scope of the present disclosure.
The container 300 may be sized to contain wine bottles, other bottles, or other items and may function as an insulated container. In the illustrated example, inner bottom wall 346 may have a diameter, D, or width of approximately 3.5″ (76.2 mm), or within a range of 3.25″ (82.55 mm) and 3.75″ (95.25 mm), or within a range of 3.0″ (230 mm) and 4″ (101.6 mm), where the diameter, D, is defined as a horizontal distance across the narrowest part of the cavity 350 at the inner bottom wall 346. Generally, most wine bottles have a diameter of approximately 3.25″ and champagne bottles have a diameter of approximately 3.5″. In addition, the cavity 350 of the container 300 may have a height greater of approximately 8.7″ (221 mm), or within a range of 8.5″ (215.9 mm) and 9″ (228.6 mm), or within a range of 8″ (203.2 mm) and 9.5″ (241.3 mm), where the height, H, is defined a vertical distance between the upper end 306 of the top opening 304 and inner bottom wall 346. The height, H, may be greater than the diameter, D. In addition, the height and diameter may be expressed as a ratio to each other. For instance, the ratio of the height, H, of the cavity 350 to the diameter, D, of the inner bottom wall 346 may be approximately 2.5:1, or within a range of 2.2:1 and 2.8:1, or within a range of 2:1 and 3.2:1.
As shown in
The outer bottom wall 312 may include a lower cavity 330. The lower cavity 330 may include an inner cavity wall 332, an outer cavity wall 334, and a bottom cavity wall 336. The lower cavity 330 may be ring-shaped such that the inner cavity wall 332 and the outer cavity wall 334 each form a continuous loop that are spaced apart from each other. The support member 360 may be placed within the continuous loop formed by the inner cavity wall 332. The inner cavity wall 332 of the lower cavity 330 may be adjacent to and in some cases contact the support member 360. The inner cavity wall 332 may help secure and align the support member 360 so the support member 360 is properly located and stays in place as it is compressed during the assembly of the container 300. While the illustrated example includes a ring-shaped lower cavity 330, the lower cavity may have other shapes such as a square, circular, oval, or other geometric shape. In other examples, the lower cavity 330 may comprise a plurality of cavities 330 arranged in a manner such that at least a portion of the cavity walls can help to secure and position the support member 360. Additionally, in examples with multiple lower cavities, each of the lower cavities may include a separate foot member, or a foot member than has a portion that is received in each of the lower cavities.
A foot bracket 370 may be located in the lower ring-shaped cavity 330. The foot bracket 370 may be connected to the bottom cavity wall 336 and may include a hook member or a plurality of hook members 372 that engage and secure the elastomeric foot member 390. The foot member 390 may be ring-shaped and form a slip resistant surface to support the container 300. In addition, a plurality of openings may be located along the bottom cavity wall 336. The openings may be round shaped holes and may be evenly spaced around the lower ring-shaped cavity 330. The plurality of openings may comprise three openings, but the number of openings may be two openings, four openings, or more than four openings. The openings may assist in evacuating the gas from the cavity formed between the outer and inner shells 310, 340. In addition, the holes may be aligned with similar openings arranged along a bottom surface of the foot bracket 370.
The support member 360 may be formed from an insulating material while also being compressible. The support member 360 may be a foam, a lattice structure, a honeycomb structure, or other solid insulating structure. In some examples, the support member 360 may also include or be formed from a heat resistant material. As discussed in more detail below when the container 300 is subjected to a vacuum during construction, the container 300 (and its components) may also be subjected high temperatures (i.e. greater than 200° C.), which may make some polymeric or fiber glass insulation materials unsuitable for use in the support member 360. As such, the support member 360 may be also heat resistant such as a heat resistant ceramic fiber insulation, an aerogel material, a ceramic fiber mat, or similar heat resistant insulation material. in addition, the support member 360 may be formed from, a ceramic material, a mineral wool material, a ceramic foam, an aerogel-based material (e.g. an aerogel blanket, an aerogel block, or similar aerogel structure), an organic material, or other high-temperature fiber-reinforced material. The support member 360 may also have a degree of porosity to help provide compressibility as wells as the desired insulating properties. For example, the support member 360 may have a porosity of greater than 60 percent, or greater than 80 percent, or even greater than 90 percent. Alternatively, the support member 360 may be incompressible, such as a fiber mat or blanket, or may be loose granules or particles that are located between the outer bottom wall 312 and the inner bottom wall 346.
The support member 360 may comprise an insulating material with a low thermal conductivity. The low thermal conductivity prevents a direct conduction pathway between the inner shell 310 and the outer shell 340. By preventing or reducing any direct conduction pathways between the shells 310, 340, the support member 360 along with the sealed vacuum cavity 320 may help to reduce or eliminate condensation due to the lack of a conduction pathway between the walls 302, 312, 342, 346 of the shells 310, 340. For example, the support member 360 may have a thermal conductivity within a range of 0.013 W/(m*K) and 0.040 W/(m*K).
In some examples, additional support members 360 may be located in different regions of the vacuum cavity 320 to help prevent or reduce deformation of one or more surfaces of the insulating container 300.
