One skilled in the art will recognize that the herein described components (e.g., steps), devices, and objects and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are within the skill of those in the art. Consequently, as used herein, the specific exemplars set forth and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific example herein is also intended to be representative of its class, and the non-inclusion of such specific components (e.g., steps), devices, and objects herein should not be taken as indicating that limitation is desired.
Each of the above U.S. patents, U.S. patent application publications, U.S. patent applications, foreign patents, foreign patent applications and non-patent publications referred to in this specification or listed in any Application Data Sheet, is incorporated herein by reference, to the extent not inconsistent herewith.
In addition to the foregoing, other system aspects are described in the claims, drawings, and text forming a part of the present disclosure.
With respect to the use of substantially any plural or singular terms herein, those having skill in the art can translate from the plural to the singular or from the singular to the plural as is appropriate to the context or application. The various singular/plural permutations are not expressly set forth herein for sake of clarity.
While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
An integrally thermally sealed container may be used to maintain a food item or items below the freeze point (generally 0° C./32° F.). For example, an integrally thermally sealed container may be used to increase the shelf-life, for example, of a fresh food item or items. In this instance, a fresh food item might include meat, fish, vegetables, fruits, bread, or dairy. The recommended shelf-life of frozen fresh food items may range from 3 months to 1 year (see, e.g., Cornell University Cooperative Extension, Foodkeeper Guide Fact Sheet, which is herein incorporated by reference). Alternatively, an integrally thermally sealed container may be used to maintain the temperature of frozen dessert items such as, for example, ice cream, frozen yogurt, ice cream bar, etc. As such, the integrally thermally sealed container may hold a single serving of the food item. Alternatively, the integrally thermally sealed container may be large enough to hold multiple servings, which may be used in a single sitting. Optionally, the integrally thermally sealed container may hold more than one type of frozen food item such as, for example, a meat and a vegetable serving or servings. The integrally thermally sealed container may contain one or more sensors, temperature indicators, communication devices or recording devices to indicate the quality or integrity of the food during the course of storage, the length of storage, or activity relative to the container during storage.
An integrally thermally sealed container may be used to maintain a liquid or beverage below the freeze point (generally 0° C./32° F.). For example, an integrally thermally sealed container may be used to maintain water, for example, in a frozen state. As such, a block or blocks of frozen liquid such as water ice obtained from an integrally thermally sealed container may be used, for example, in an emergency setting to keep food or medicines cold in a refrigerator, ice chest, or other insulated container. Optionally, a block or blocks of frozen liquid such as water ice obtained from an integrally thermally sealed container may be used in a setting where power for refrigeration is not available or is limited, such as, for example, a field station, a military outpost, a refuge camp, a forest service outpost, a climbing or other expedition, or for recreational outings.
An integrally thermally sealed container may be used to maintain a food item or items at a specific temperature, such as that maintained by standard refrigeration, generally in the range 37-40° F. (3-4.5° C.). An integrally sealed container may keep foods in an appropriate temperature range, neither excessively warm or cool, during storage or transport. For example, an integrally thermally sealed contained may be used to maintain fresh, non-pasteurized caviar, for example, for 4 weeks in the range of 37-40° F. (see, e.g., Cornell University Cooperative Extension, Foodkeeper Guide Fact Sheet, which is herein incorporated by reference). Similarly, an integrally thermally sealed container may be used to maintain hard cheeses for 6 or more months in the range of 37-40° F., for example.
An integrally thermally sealed container may be used to maintain a liquid or beverage within a specific temperature range during storage or transport. A liquid or beverage might be water or flavored water, dairy product or fruit juice, carbonated soda, wine, beer or distilled spirits, for example. A specific temperature may be that at which the liquid or beverage is best stored, for example, for long term aging. For example, an integrally thermally sealed container may be used to store wine at an optimal storage temperature range, generally 50 to 55° F. (10-12° C.). Similarly, an integrally thermally sealed container may be used to store beer at a storage temperature range, generally 45-65° F. Alternatively, a specific temperature may be that at which a liquid or beverage is preferably served. For example, an integrally thermally sealed container may store a beverage in a temperature range of 37-40° F. (3-4.5° C.), comparable to a standard electric refrigerator. Alternatively, an integrally thermally sealed container may store a beverage such as beer, for example, at a temperature appropriate for serving depending upon the type of beer, ranging for example from 37 to 53° F. (3-12° C.). The beverage may be directly packaged into the integrally thermally sealed container. Alternatively, the beverage may be packaged separately into a can, carton, or bottle, for example, and than further packaged in the integrally thermally sealed container. The integrally thermally sealed container may contain a single or multiple servings of the liquid or beverage, which may be used in a single sitting.
An integrally thermally sealed container may be used to keep fluids intended for intravenous administration at or slightly above body temperature. In a medical or surgical setting, for example, an integrally thermally sealed container may be used to hold artificial plasma or other blood product at appropriate temperature for immediate use. For example, plasma substitutes such as hydroxylethyl starch (HES) are often administered rapidly to patients with hypovolemia and for hemodilutional autotransfusion (HAT) during surgery and anesthesia (Yamakage et al. Safety and beneficial effect on body core temperature of prewarmed plasma substitute hydroxyethyl starch during anesthesia, Anesthesiology (2004) 101:A1285, which is herein incorporated by reference). Addition of these agents at room temperature may result in a drop in the patient's core temperature. HES has been shown to be stable at 40° C. for at least 3 months. As such, a blood product or plasma substitute such as HES, for example, may be stored at 40° C., for example, in an integrally thermally sealed container until needed in a medical or surgical setting.
Alternatively, an integrally thermally sealed container may be used to maintain an intravenous solution at or slightly above body temperature (generally 98.6° F./37° C.). For example, an integrally thermally sealed container may contain a solution of dextrose or saline for use, for example, in treating dehydration associated with hypothermia. As the core temperature of a hypothermic individual is already below normal, addition of intravenous fluids should optimally be performed at normal body temperature to prevent further cooling (Department of Health & Social Services, State of Alaska, Cold Injuries Guidelines Revised version 2005, which is herein incorporated by reference). As such, an integrally thermally sealed container containing a prewarmed rehydration solution may be used, for example, by first responders in the field such as a paramedic, an emergency medical technician, search and rescue, coast guard, or military personnel.
An integrally thermally sealed container may also be used to maintain an object at a specific temperature. For example, an integrally thermally sealed container may be used to keep a blanket prewarmed, for example, for use in an emergency or medical setting. A hospital setting might include using a prewarmed blanket from an integrally thermally sealed container to prevent hypothermia at birth in preterm and/or low birth weight babies (Cohen et al. Thermal efficiency of prewarmed cotton, reflective, and forced-warm-air. Int. J. Trauma. Nurs. (2002) 8:4-8, which is herein incorporated by reference). A prewarmed blanket may be used in an emergency situation to treat an individual exhibiting signs of shock or hypothermia. In the instance where the individual is conscious, the warm blanket may be used to completely wrap the body. In the instance where the individual is unconscious and the peripheral vasculature has become constricted and acidic, the warm blanket or parts of the warm blanket may be used to warm the torso, groin, neck, armpits and/or head and as such prevent further loss of core body temperature (Department of Health & Social Services, State of Alaska, Cold Injuries Guidelines Revised version 2005, which is herein incorporated by reference). It is anticipated that an integrally thermally sealed container may be used to hold other items for warming a body or extremities such as for example towels, hat, gloves, socks, pants, shirt, or a combination thereof.
An integrally thermally sealed container under pressure may be used to maintain humidified air or oxygen in the range 43-45° C. (107-122° F.), for example. In a hypothermic individual, loss of heat during respiration may account for 10% to 30% of the body's heat loss, particularly under conditions in which the ambient air temperature is cold. As such, inhalation of warm, water-saturated air is a non-invasive treatment suitable for active core rewarming in the field and donates heat directly to the head, neck, and thoracic core, warming the hypothalamus, the temperature regulation center, the respiratory center, and the cardiac center at the base of the brainstem. (Department of Health & Social Services, State of Alaska, Cold Injuries Guidelines Revised version 2005, which is herein incorporated by reference). In many cases, this rewarming of the central nervous system at the brainstem reverses the cold-induced depression of the respiratory centers and improves the level of consciousness. Alternatively, an integrally thermally sealed container may contain water ranging in temperature, for example, from 99 to 212° F. (37-100° C.) that may be used in conjunction with a face mask to provide prewarmed, humidified air to a hypothermic individual. For example, inhaled ambient air may be passed over steaming, prewarmed water prior to entering an individual's lungs.
An integrally thermally sealed container may be used to maintain water, for example, at a temperature appropriate for bathing or cleaning dishes, clothes, or equipment in the field. For example, an integrally thermally sealed container may contain water at a temperature range of 80 to 100° F. for a “field shower” for use by military, forest service, or first responders, for example, in an emergency following exposure to a hazardous chemical or agent. For example, an integrally thermally sealed container may contain water at a temperature range of 80 to 100° F. for cleaning dishes or other items in remote regions, disaster areas or war zones.
An integrally thermally sealed container may be used to maintain water at or just below boiling temperature, generally 212° F./100° C. In some settings, the water may be sterilized. Boiling water may be used for heating and cooking a variety of ready to eat items such as, for example, beverages including coffee, tea, hot chocolate, and cider, and foods including dehydrated foods and instant soup, noodles, and oatmeal. As such, the integrally thermally sealed container containing water at or near boiling may be used in an emergency or remote setting, for example, when the capacity to heat water is unavailable or inconvenient.
An integrally thermally sealed container may be used to maintain a non-edible liquid at a specific temperature to facilitate immediate use. For example, an integrally thermally sealed container may contain ready to use hot mix asphalt maintained within an optimal spreading temperature range, generally 280 to 300° F. Hot mix asphalt is routinely used for large paving projects and is manufactured at a local hot mix asphalt facility and delivered to the paving site already warm and ready to be used. As such, hot mix asphalt maintained at temperature in an integrally thermally sealed container may be used in those situations in which a local hot mix asphalt facility is not available, for example after damage to a road or an airfield in a remote location, disaster area or war zone. Alternatively, hot mix asphalt maintained at temperature in an integrally thermally sealed container may be used for a patching project or projects requiring immediate attention by a road or airstrip crew. Optionally, an integrally thermally sealed container may be used to maintain new formulations of asphalt such as, for example, warm mix asphalt at temperature ranges of 160-180° F. (Suttmeier, Warm mix asphalt: a cooler alternative (2006) Material Matters, Spring:21-22, which is herein incorporated by reference).
An integrally thermally sealed container may be used to maintain a solution of deicing material, such as, for example, ethylene glycol, propylene glycol, salt solutions, urea solutions, or a combination thereof at a temperature appropriate to facilitate removal of ice, snow and/or frost. Propylene glycol is capable of lowering the freezing point of water to about −60° C. and is a common component of solutions used to deice airplanes, for example. Propylene glycol in combination with water and additional salts and/or urea is usually sprayed on hot, in the range of 150 to 180° F., and at high pressure. A small amount of deicing material, for example 25-50 gallons, may be used on an otherwise dry day to warm fuel tanks. Alternatively, as much as 1700 gallons of deicing material have been reportedly used per plane during heavy snow fall. As such, an integrally thermally sealed container may be configured to contain, for example, 25-50 gallons of prewarmed deicing material for minimal deicing of a plane. Alternatively, an integrally thermally sealed container may be configured to contain a large capacity (500 to 1000 gallons), for example, of prewarmed deicing material.
