DETAILED DESCRIPTION OF THE INVENTION
Definitions

Container means a dispenser, bottle, flask, tub, jar or other article which together with one or more other articles including a lid, top, cap or spout can be used to form a gas sealed article. Displaced means transferred with or without pumping. Gasses include one or more substances in the gaseous phase, for example gasses include air which comprises a mixture of at least oxygen, nitrogen and water. Exposure means physical or chemical contact allowing a physical or chemical reaction. Pumping means applying suction to a compartment of a container either via a manual or mechanized action, including applying a force to a diaphragm or squeezing the container wall. A one-way conditional valve allows gas to pass through the valve in one specified direction when the valve is not activated and allows gas to pass through the valve in the reverse direction only when the valve is activated. A one-way non conditional valve allows gas to pass through the valve in one specified direction. A one-way valve can include a one-way conditional valve and a one way non conditional valve. Organelle refers to a membrane that acts in the fashion of a biological membrane. An inner diaphragm can change to the adjusted first compartment volume by either expanding or contracting to adjust to a greater or reduced volume respectively. An organelle is used to describe an inner diaphragm and an outer diaphragm that are formed in a single process, or formed from a single material or as a single entity. In an embodiment of the invention, where the inner diaphragm and the outer diaphragm are made separately and assembled together as a single entity, the organelle is then fitted onto the rim. Substance includes food and drink in which the spoilage of the substance can be delayed by removing reactants from the substance's environment. Reactants are molecules that physically or chemically react with the reactive substance and include air, gasses, water and liquids which are capable of oxidizing food and drink. Reactants also include gaseous odors which can become physically adsorbed to molecules in food and drink.

Containers or other storage systems that limit the access of airborne agents have been shown to produce very good results in protecting food from certain microorganisms, bacteria, pests, mould and fungal growth. This principle also applies for non-food substance that would harbor the growth of the microorganisms, bacteria, pests, mould and fungi. Furthermore, the container helps to prevent the food from oxidizing. One way to improve the storage of food is to replace the air and more specifically the oxygen in a container containing the food with an inert gas. If the inert gas is heavier than air, it can readily be trapped in the container and will not be displaced by air. The requirement of keeping an inert gas available at all times and the cost of the inert gas and storage equipment limit the applicability of this approach. An alternative approach is to remove the oxygen without replacing it with an inert gas, such that the oxygen cannot seep back into the container, i.e., to keep the food in a container under vacuum.

Removing the air also helps remove excess moisture and thereby theoretically should also maintain the moisture level of the food. Air can be removed from a vessel by the formation of a vacuum. However, a problem with generating a vacuum is that the vacuum causes the food to release liquids. In the case of cellular substances, the vacuum can disrupt the cell membranes and as a result moisture can be sucked out of the substance. The release of liquids can generate an environment that actually accelerates food spoilage. A strong vacuum is generally not suitable for storing a liquid, since the liquid will bubble violently as any air in the liquid is removed and thereby splatter onto the inside container surfaces. When applied for extended periods of time, the vacuum can concentrate a liquid as the volatile components of the liquid are essentially ‘boiled off’.

In an embodiment of the invention, the air surrounding oxidation- or moisture-sensitive material in a storage container is replaced by altering the shape of the container top surface to mimic the shape of the material. In an alternative embodiment of the invention, the air surrounding oxidation- or moisture-sensitive material in a storage container is replaced by altering the shape of the container bottom surface to mimic the shape of the material. In another embodiment of the invention, the air surrounding oxidation- or moisture-sensitive material in a storage container is replaced by altering the shape of one or more of the container side surface to mimic the shape of the material. In an embodiment of the invention, the air surrounding food in a storage container is replaced by altering the shape of the container top, bottom, or one or more of the side surface to mimic the shape of the food. In an embodiment of the invention, the air surrounding a gas or liquid in a storage container is replaced by altering the shape of the container top, bottom, or one or more of the side surface to mimic the shape of the liquid. In another embodiment of the invention, the air surrounding oxidation- or moisture-sensitive material in a storage container is replaced by altering the shape of the container top, bottom, or one or more of the side surface to mimic the shape of the oxidation- or moisture-sensitive material, and generating mild vacuum conditions that do not cause the suction of liquids out of the oxidation- or moisture-sensitive material. In another embodiment of the invention, the air surrounding food in a storage container is replaced by altering the shape of the container top, bottom, or one or more of the side surface to mimic the shape of the food, and mild vacuum conditions are created that do not cause suction of fluids out of the food. In another embodiment of the invention, the air surrounding liquids in a storage container is replaced by altering the shape of the container top, bottom, or one or more of the side surface to mimic the volume of the container occupied by the liquid, and mild vacuum conditions are created that do not cause suction of air out of the liquid. In various embodiments, oxidation of oxidation-sensitive material can be reduced by reducing the volume of air in contact with the oxidation-sensitive material. In various embodiments, spoilage of moisture-sensitive material can be reduced by reducing the volume of air in contact with the moisture-sensitive material.

In an embodiment of the present invention, a storage system minimizes oxidation of food stored at room temperature or ambient temperature for relatively short periods of time (e.g., food that is packed for carryout picnics, catering or lunch boxes). In an embodiment of the present invention, a storage system minimizes oxidation of stored gasses or liquids that are stored at room temperature or ambient temperature. In another embodiment of the present invention, a storage system minimizes spoilage of solids, liquids or gasses stored at 4° C. In an alternative embodiment of the present invention, a storage system minimizes spoilage of solids, liquids and gasses stored at minus 20° C. In an alternative embodiment of the present invention, a storage system minimizes the moisture in contact with the material and thereby minimizes the moisture required for many types of bacteria, mold and fungus to survive. In an alternative embodiment of the invention, a storage system isolates stored liquids and gasses from the atmosphere or other reactive agents, or from dispersing.

In an embodiment of the present invention, a rigid container with defined dimensions can be equipped with an internal flexible diaphragm to modulate the inner volume of the container. In an embodiment of the present invention, by reducing the volume of the container, much less air is available to cause oxidation of the food. In an embodiment of the present invention, by replacing the air with a mild vacuum, less moisture is available to cause spoilage of the food.

In various embodiments of the present invention, the vacuum applied to material in a storage container can be between approximately 700 Torr and approximately 10 Torr. In an embodiment of the present invention, a vacuum applied to material in a storage container can be approximately 400 Torr. The phrase “approximately in the pressure range of 400 Torr” typically equates to a pressure of more than 200 Torr and less than 600 Torr. In an embodiment of the present invention, a vacuum applied to material in a storage container can be approximately 100 Torr. The phrase “approximately in the pressure range of 100 Torr” typically equates to a pressure of more than 80 Torr and less than 120 Torr.

In an embodiment of the present invention, one or more diaphragms can be vacuum seal attached to a rim of a container. The rim can make a vacuum seal with the body of the container. In an embodiment of the invention, a soft rubber gasket and clamps can be used to form the vacuum seal between the rim and the container. U.S. Pat. No. 7,040,356 describes a soft rubber gasket that forms a vacuum seal by means of a cam and lever. U.S. Pat. No. 7,040,356 is explicitly incorporated by reference into this application in its entirety. The diaphragms can be adhesively sealed to the rim using materials including modified polypropylene or modified polyethylene. In an alternative embodiment of the invention, the diaphragms can be vacuum seal attached to the rim of the container with a heat seal. U.S. Pat. No. 5,743,942 describes uncoated but compatible film materials that form stronger seals than adhesive coated seals. U.S. Pat. No. 5,743,942 is explicitly incorporated by reference into this application in its entirety.

A first conditional one-way direction valve can be positioned at the periphery of the rim, allowing only gasses to leave the container volume and creating a vacuum inside the container. European Patent No. 0644128 describes a one-way conditional valve received in a cylindrical depression in the container rim. One-way conditional valves or push-button manual relief valves that can be mounted in panels are available commercially from a number of suppliers including Smart Products (http://www.smartproducts.com/), where the 330 manual relief valve can be received in any 300 series modular check valve. These valves can be releasably received in a panel or other surface to give a vacuum seal.

In an embodiment of the invention, an annular periphery of a depression forms a sealing surface within a one-way conditional valve. If gasses are pressurized within the container, then a one-way conditional valve opens and the gasses flow out of the container. In an embodiment of the invention, the one-way conditional valve closes as soon as the pressure in the container is less than the pressure outside the container. In an embodiment of the invention, the one-way conditional valve is located in the rim. In an embodiment of the invention, the one-way conditional valve is formed by a diaphragm that is elastically pre-stressed in its initial position so that the diaphragm blocks the flow path when the diaphragm is in the rest state. In the evacuated state, the rim can no longer be separated from the container because the force on the sealing surface between the rim and the container is too great, due to the existing pressure difference. As a result, in order to subsequently open the container to remove the food, the vacuum in the container space must first be released. In an embodiment of the invention, the opening of the valve is achieved by manually pulling on a pin formed on the sealing sleeve until the sealing surface of the valve lifts away from the valve seat. Alternatively, the opening of the valve may be achieved via squeezing on the valve in such a way that it forces the valve out of its position so that air or other gasses can traverse the valve freely and flow according to the pressure difference on both sides of the valve. Air or gasses are then able to flow into the container until the pressure in the atmosphere and the pressure in the container are equalized. After the pressure has been equalized, the cover can be easily removed from the container, and food can be removed from the container. In an embodiment of the present invention, a one-way conditional valve is used according to European Patent No. 0644128. European Patent No. 0644128 is explicitly incorporated by reference into this application in its entirety.

In an embodiment of the present invention, when the first conditional one-way direction valve is activated or depressed, gasses can traverse in the opposite direction from outside the container into the container to release the vacuum. The outer diaphragm can be made from natural latex rubber or a material with similar flexural modulus. U.S. Pat. No. 6,051,320 discloses a thin walled natural rubber latex material that would be suitable for forming the outer diaphragm and is explicitly incorporated by reference into this application in its entirety. A conditional one-way direction valve can be inserted into the outer diaphragm which allows air to pass from outside the container through the valve into the container void compartment between the outer diaphragm and the inner diaphragm. When this conditional one-way valve is depressed, gas can traverse in the opposite direction from the container void between the outer diaphragm and the inner diaphragm out of the container.

In an embodiment of the present invention, the inner diaphragm can be made of rubber with a flexural modulus greater than the outer diaphragm. In an embodiment of the present invention, the inner diaphragm is made of a rubber/silicon material. U.S. Pat. No. 4,257,934 which is explicitly incorporated by reference into this application in its entirety describes a number of rubber-based materials with additives that increase the flexural modulus of the material by up to 100%. In an alternative embodiment of the present invention, the inner diaphragm is made of a polymer material with a thin layer of silicon dioxide. U.S. Pat. No. 5,279,873 describes a composite material made from a polymer layer with a transparent thin layer of silicon oxide provided on one surface of the polymer layer that is able to act as a barrier to helium and other larger atomic radii gasses and that would be suitable for the inner membrane. The polymer base layer is selected from one or more materials including nylon film, nylon film coated with a vinylidene chloride resin, polyester film, polyethylene terephthalate film coated with a vinylidene chloride resin, polypropylene film, ethylene-vinyl alcohol copolymer film, polyethylene film, polyvinyl alcohol film, and polyvinylidene chloride film. The silicon oxide layer has an atomic ratio of silicon to oxygen of approximately 1:0.3 to 2. U.S. Pat. No. 5,279,873 is explicitly incorporated by reference into this application in its entirety. In another embodiment of the present invention, the inner diaphragm is made of latex. In another alternative embodiment of the present invention, the inner diaphragm is made of polyethylene, polypropylene or blends thereof. In an embodiment of the present invention, the inner diaphragm is made of ethylene vinyl alcohol copolymer or saran which is substantially impervious to oxygen. U.S. Pat. No. 4,542,029 which is explicitly incorporated by reference into this application in its entirety describes polyethylene, polypropylene, ethylene vinyl alcohol copolymer, saran for sealing containers. In another embodiment of the present invention, the inner diaphragm is made of Diolon, a low-oxygen permeability film. The inner diaphragm can be expanded into the void of the container. As a result when mechanical force is exerted on the outer diaphragm, both the outer diaphragm and inner diaphragm are forced into the container and the inner diaphragm replaces the air that is forced out of the container through a conditional one-way valve. On releasing the force, the outer diaphragm returns to its normal position while air entering through a second conditional one-way valve fills the container void between the outer diaphragm and the inner diaphragm. In an embodiment of the invention, a lid can be placed on top of the container rim and the container can be stored.

As shown in FIG. 1A, when a material needs to be stored in a preservation storage system 100 a user can attach the rim 170 to the container 110 and then apply a force 160 on the outer diaphragm 140 pitch. Two one-way valves can be located on the preservation storage system. A first one-way valve 150 can connect the inside of the container to the outside. A second one-way valve 130 can bypass the outer diaphragm to let air into the void between the outer diaphragm and the inner diaphragm. The two one-way valves 130 and 150 can create a simple pump that will suck air from inside the container 180 out through the first one-way valve 150 outside the container 190. As the force 160 is removed, air can be drawn through the second one-way valve 130 into the container void space 185 between the inner diaphragm 122 and the outer diaphragm 140. The force 160 can be applied and released repetitively acting on the diaphragms 140 and 122 to act as a pump to expand the inner diaphragm 122 into the container void 185 and generate the vacuum inside the container 180 and around the contents of the container.

As shown in FIG. 1B, after the force has been released the inner diaphragm 122 extends towards the inside of the container 180 and the container void space 185 between the diaphragms 140 and 122 has increased in volume. In this static situation, the first one-way conditional valve 150 does not allow air back into the container. The second one-way valve 130 does not allow the air trapped in the container void 185 to escape outside the container. In an embodiment of the invention, a lid 120 can then be placed on top of the rim and the outer diaphragm 140 and the preservation storage system 100 can be placed in a refrigerator or other cold storage area for storage. In an embodiment of the invention, the dimensions of the base 112 of the container 110 allow one container 110 to be stacked on top of the lid 120 of another container 110. In an alternative embodiment of the invention, the base 112 of the container 110 allows one container 110 to be stacked on top of the rim of another container 110.

In an embodiment of the invention, in order to access the contents of the container, the rim 140 (see FIG. 1A) can be removed from the container 110 by simply removing the lid 120 and pressing on a first conditional one-way valve 150 to release the vacuum in the container. The rim 170 and the diaphragms 140 and 122 can then be removed from the container 110 and the contents of the container removed. In order to release the air trapped between the inner 122 and outer 140 diaphragms a second conditional one-way valve 130 can be depressed. Once the pressure is released, the inner diaphragm 122 will naturally flex back to its original position.

FIG. 2A shows a cross-section of the vacuum container rim system 200 where the outer diaphragm 240 and the inner diaphragm 222 are both connected with a vacuum seal to the rim 270. The first one-way valve 250 can be located anywhere in the periphery of the rim 270 that does not interfere with the action of the inner diaphragm. The second one-way valve 230 can be located in the center of the outer diaphragm 240. A lid can be placed on top of the vacuum container rim system 200. FIG. 2B shows a view from above the vacuum container rim system 200 where the outer diaphragm 240 connects with the rim 270 at circumference 272. The first one-way valve can be located in the periphery of the rim 250. The second one-way valve 230 can be located in the center of the outer diaphragm 240. FIG. 2C shows a perspective view of the vacuum container rim system 200 where the outer diaphragm 240 is connected to the rim 270. A first one-way valve can be located in the rim 250. The second one-way valve 230 can be located in the center of the outer diaphragm 240.

FIG. 3A shows a cross-section of an alternative embodiment of the invention, where a vacuum container flask system 300 with an outer diaphragm 340 and an inner diaphragm 322 are both connected with a hermetic seal to one or both the flask rim 370 and the flask 310. The first one-way valve can be located at the spout exit 383 or anywhere along the spout 386 (in an alternative embodiment of the invention, a first one way conditional valve can be located at the exit of the container 350, and a probe can be inserted up the spout to activate the valve). The first one-way valve 383 allows liquid or gasses 380 to leave the container flask system 300 only and prevents air from flowing into the container flask system 300 such that the liquid or gasses 380 can be isolated from contact with air until the liquid or gas is pumped out. The second one-way valve 330 can be located at the top of the container flask system 300 in the center of the outer diaphragm 340 or anywhere associated with the outer diaphragm 340. The liquid and/or gas 380 to be dispensed (or a solid which liquefies or sublimes) can be stored in the bottom of the flask 300. A delivery vent 388 that extends to the bottom of the container 389 can run up the side of the vacuum container flask system 300 and can be connected to the spout 386 through the opening 350. In an embodiment of the invention, an optional third valve can be used to control flow out of the opening 350.

FIG. 3B shows a section of the flask shown in FIG. 3A, where a vacuum container flask system 300 with an outer diaphragm 340 is connected with a hermetic seal to one or both the flask rim 370 and the flask 310.

FIG. 3C shows a cross-section of the vacuum container flask system 300 shown in FIG. 3A, with an outer diaphragm 340 and an inner diaphragm 322 both connected with a hermetic seal to one or both the flask rim 370 and the flask 310. The first one-way valve can be located at the spout exit 383 or anywhere along the spout 386 (in an alternative embodiment of the invention, a first one way conditional valve can be located at the exit of the container 350, and a probe can be inserted up the spout to activate the valve). The first one-way valve 383 allows liquid or gasses 380 to leave the container flask system 300 only and prevents air from flowing into the container flask system 300 such that the liquid or gasses 380 can be isolated from contact with air until the liquid or gas is pumped out. The second one-way valve 330 can be located at the top of the container flask system 300 in the center of the outer diaphragm 340 or anywhere associated with the outer diaphragm 340. The liquid and/or gas 380 to be dispensed (or a solid which liquefies or sublimes) can be stored in the bottom of the flask 300. A delivery vent 388 which extends to the bottom of the container system 389 can run up the side of the vacuum container flask system 300 and can be connected to the spout 386 through the opening 350. An optional third valve can be used to control flow out of the opening 350.

In an embodiment of the invention, the gas and/or liquid 380 is expelled from the container flask system 300 by using the inner 322 and outer 340 diaphragms as a pump to eject the gas and/or liquid 380 through the delivery vent 388 and the one way valve 350. In various embodiments of the invention, as the liquid 380 is used, the inner diaphragm 322 can extend to increase the container void space 385 in the inner 322 diaphragms and ensure that the liquid and/or gas 380 does not come in contact with air.

FIGS. 3D and 3E show a cross-section of the vacuum container flask system 300 with a screw cap 382 which inserts into the flask rim 370, an outer diaphragm 340 and an inner diaphragm 322 both connected with a hermetic seal to one or both the flask rim 370 and the flask 310. The first one-way valve can be located at or near the top of the container 350 (in an alternative embodiment of the invention, the container can include a spout and a first one-way conditional valve can be located anywhere along the spout). The first one-way valve 350 allows gas or liquid 380 to leave the container flask system 300 only and prevents air from flowing into the container flask system 300 such that the gas and/or liquid 380 can be isolated from contact with air until it is pumped out. The second one-way valve 330 can be located at the top of the container flask system 300 in the center of the outer diaphragm 340 or anywhere associated with the outer diaphragm 340. The liquid and/or gas 380 to be dispensed can be stored in the bottom of the flask 300. A delivery vent 388 which extends to the bottom of the container system 389 can run up the side of the vacuum container flask system 300 and can be connected to the one-way valve 350. An optional spout can be attached to the one-way valve 350. In FIG. 3D the inner diaphragm 322 has not been extended and the void compartment 385 is small. This would correspond with the situation before a significant amount of the container contents had been dispensed or before the pump had been used to generate a vacuum. In FIG. 3E the inner diaphragm 322 has been significantly extended and the void compartment 385 is large. This would correspond with the situation after a significant amount of the container contents had been dispensed.

In the alternative embodiment of the invention shown in FIGS. 3F-3H, the inner diaphragm 322 can be positioned at the bottom of the container flask system 300 and can expand upwards such that the gas and/or liquid 380 can be forced upwards (towards the top of the container flask system 300). FIGS. 3F-3H show cross-sections of the vacuum container flask and cap system 300, in which a cap 382 inserts into the flask rim 370 where the cap includes an outer diaphragm 340 connected with a hermetic seal to the cap 382. An inner diaphragm 322 connects with a hermetic seal to one or both the flask 310 and the flask rim 370. The first one-way valve can be located at or near the top of the container 350 (in an alternative embodiment of the invention, the container can include a spout and a first one-way conditional valve can be located anywhere along the spout and a probe can be inserted up the spout to activate the valve). The first one-way valve 350 allows gas or liquid 380 to leave the container flask system 300 only and prevents air from flowing into the container flask system 300 such that the gas and/or liquid 380 can be isolated from contact with air until it is pumped out. The outer diaphragm 340 can be located in the cap 382 at the top of the container flask system 300. The liquid and/or gas 380 to be dispensed can be stored in the flask 300. A delivery vent 388 which extends to the bottom of the container system 389 can run up the side of the vacuum container flask system 300 and can be connected to the one-way valve 350. A second one way valve positioned at the bottom of the flask 335 can be used to allow air from outside the container into the void compartment 385. In FIGS. 3G and 3H the cap 382 is a screw cap which screws into the flask rim 370.

In FIG. 3G the inner diaphragm 322 has not been extended and the void compartment 385 is small. This would correspond with the situation before a significant amount of the container contents had been dispensed or before the pump had been used to generate a vacuum. In FIG. 3F the inner diaphragm 322 has been extended and the void compartment 385 is larger than in FIG. 3G. This would correspond with the situation after a significant amount of the container contents had been dispensed. In FIG. 3H the inner diaphragm 322 has been significantly extended and the void compartment 385 is large. This would correspond with the situation after most of the container contents had been dispensed.

In an embodiment of the invention, (see FIGS. 3F and 3H) the inner diaphragm can be designed to expand with a trunk 323 of less flexible material compared with the bulbous portion of the inner diaphragm 322. This arrangement will allow for the inner diaphragm 322 to inflate from the top and keep the liquid at the bottom leaving the container through the delivery vent 388.

In an embodiment of the invention, the gas and/or liquid 380 is expelled from the container flask system 300 by squeezing on the container flask rather than pressing on an outer diaphragm. FIGS. 3J and 3K shows a cross-section of the vacuum container flask system 300, with an inner diaphragm 322 connected with a hermetic seal to one or both the flask rim 370 and the flask 310. The first one-way valve can be located near the top of the container 350 (in an alternative embodiment of the invention, a first one way conditional valve can be located or at the spout 386 exit 383). The first one-way valve 350 allows liquid or gasses 380 to leave the container flask system 300 only and prevents air from flowing into the container flask system 300 such that the liquid or gasses 380 can be isolated from contact with air until the liquid or gas is pumped out. The second one-way valve 330 can be located at or near the top of the container flask system 300. The liquid and/or gas 380 to be dispensed (or a solid which liquefies or sublimes) can be stored in the bottom of the flask 300. A delivery vent 388 which extends to the bottom of the container system 389 can run up the side of the vacuum container flask system 300 and can be connected to the spout 386 through the one-way valve opening 350. An optional third valve can be used to control flow out of the spout 383.

In FIG. 3J the inner diaphragm 322 has not been extended and the void compartment 385 is small. This would correspond with the situation before a significant amount of the container contents had been dispensed or before the pump had been used to generate a vacuum. In FIG. 3K the inner diaphragm 322 has been significantly extended and the void compartment 385 is large. This would correspond with the situation after a significant amount of the container contents had been dispensed.

In various embodiments of the invention, the gas and/or liquid 380 is expelled from a container flask system 300 by using the inner 322 and outer 340 diaphragms as a pump to eject the gas and/or liquid 380 through the spout 386, as shown in FIGS. 3A, 3C, 3J and 3K. In an embodiment of the invention, as the gas and/or liquid 380 is used, the inner diaphragm 322 can extend to increase the container void space 385 and ensure that the gas and/or liquid 380 does not come in contact with air. In another embodiment of the invention, as the gas and/or liquid 380 is used, the inner diaphragm 322 can extend to increase the container void space 385 and ensure that the gas and/or liquid 380 does not come in contact with additional air.

In an embodiment of the invention, the air can be pumped out of the container flask system 300. FIGS. 3E, G and H show a cross-section of the vacuum container flask system 300 with a screw cap, where the outer diaphragm 340 is connected with a vacuum seal to the screw cap, while the inner diaphragm 322 is connected with a vacuum seal to the flask rim 370. In these embodiments, the liquid 380 can be accessed by unscrewing the cap 382 and pouring the liquid 380 out of the flask container system 300. In an embodiment of the invention, the cap 382 can make a hermetic screw fit with the container flask system 300. The cap 382 can be screwed back onto the container flask system 300 and the air can be pumped out simultaneously as the inner diaphragm 322 is inflated to expand to occupy the volume in the flask container system 300 not occupied by the liquid 380 according to the same principle. The remaining liquid 380 can be stored for later use. A first one-way conditional valve 350 allows air out only. A second one-way conditional valve 330 is “in only” and can be located in the center of the outer diaphragm 340. A liquid 380 can be stored in the bottom of the flask 300. A small tube or pipe 388 runs up the side of the vacuum container flask system 300 and is connected with the first one-way conditional valve 350. The delivery vent 388 has a slot or groove opening exposed towards the inside of the container flask system 300. As the inner diaphragm 322 inflates it pushes against the slot or groove opening in the delivery vent 388 and makes a contact seal that allows the delivery vent 388 to act as an evacuation tube and to evacuate the air inside the flask container system 300 from the section of the delivery vent 388 where the inner diaphragm is sealing the slot or groove opening. As a result the delivery vent 388 extends only as far as the inner diaphragm 322 so that the air is expelled from inside the flask container system 300, up the delivery vent 388 and out of the container system 300. Thus, the air travels via the delivery vent 388 to the first one-way conditional valve 350 and out the container flask system 300. This embodiment ensures that the air is always evacuated as the inner diaphragm 322 is expanded from the unexpanded point, until the inner diaphragm 322 has expanded to the interface between the air and liquid 380. In this manner, no air is trapped in the container flask system 300. In an embodiment of the invention, once the liquid 380 starts traveling up the delivery vent 388, the force being applied to generate the pumping can be stopped. In another embodiment of the invention, the pumping can be stopped as the first drop of liquid 380 is exiting the first one-way valve. In an alternative embodiment, the one-way valve can be chosen so that it can only be traversed by air and not by liquid 380. In these embodiments, the conditional one-way valves 330, 335 and 350 allow air to be vented into the container or air vented out of the void compartment wherein the container and diaphragms can be cleaned and available for re-use.

As depicted in FIGS. 3F-3H in various embodiments of the invention, there is no constraint on the direction on the pump. In an embodiment of the invention, the outer diaphragm 340 does not overlap with the inner diaphragm 322. In an embodiment of the invention, the outer diaphragm 340 can be placed on top of the first one-way conditional valve 350 and the pumping action can suck the air out of the container flask system 300 while forcing an inner diaphragm 322 to expand into the container flask system 300 from a different position within the flask container system 300. In this embodiment, a third one-way valve is located to connect the inner diaphragm with the flask 310 and allow air to enter the void compartment 385 and the inner diaphragm 322. In this embodiment, to expand the inner diaphragm 322 and remove the air from inside the container 300, the outer diaphragm 340 is depressed and the air is forced out the first one-way conditional valve 350, after releasing the force from the outer diaphragm 340, air is sucked into the container through the third one-way valve 335 to extend the inner diaphragm 322 into the container 300 in place of the air that is pumped out the second one-way valve 350. The pumping can occur as the user releases the pressure from the outer diaphragm 340 and it flexes back outwards. In this embodiment of the invention, the first one-way valve 350 will allow air to leave the container only, while the second one-way valve 335 will be “in only”. The inner flexible diaphragm 322 can be located anywhere on the container rim, bottom, handle or the periphery. In an embodiment of the invention, the pump can be located on the screw cap 382 and the inner diaphragm 322 can extend inwards from the bottom as a trunk 323 that has a softer bulbous inner diaphragm 322, while the liquid 380 remains at the bottom replacing the air from the upper part of the container flask system 300.

In an embodiment of the invention (see FIGS. 3F-3H) the gas or liquid can also be stored at the top of the flask container system. In an embodiment of the invention, the inner diaphragm 322 can be positioned at the bottom of the container flask system 300 such that the gas or liquid 380 can be forced upwards (towards the top of the container flask system 300) as the air is evacuated out of the container flask system 300.

In various embodiments of the invention, (see FIGS. 3J and 3K) the flexible properties of the container can be used as the pumping method and the modulation of its volume will force the liquid out of the inner diaphragm and the flask container system 300. In an embodiment of the invention, the container flask system 300 can be squeezed to force a gas or liquid 380 out of the container flask system 300 and an inner diaphragm 322 can be filled with air to compensate for the volume of the gas or liquid 380 expelled. In this embodiment of the invention, the flexible properties of the container can be used as the pumping method and the modulation of its volume will force the gas or liquid 380 out of the flask container system 300. Releasing the grip on the flask container system 300 can allow air into the inner diaphragm 322 container void space 385. Applying pressure on the container flask system 300 at any point (sides, bottom, handle or cap) can reduce the inner volume of flask container system 300 and force some gas or liquid 380 out the first one-way conditional valve 350 and dispensed out the spout 386. As the container flask system 300 flexes back to its original position, the inner diaphragm 322, which can be located anywhere on the container flask system 380, expands inwards, as the container flask system 300 expands back outwards. The increase in the inner diaphragm 322 can be commensurate with the increase in volume of the container flask system 300. The second one-way conditional valve 330 ensures that the inner diaphragm 322 cannot deflate backwards as the pressure is reapplied and the flask container system 300 is squeezed again to force more liquid 380 out of the flask container system 300. Thus, the air in the container void space 385 between outer diaphragm 340 and the inner diaphragm 322 cannot be forced out the second one-way conditional valve 330 since this valve only allows air to flow into the container void space 385. In this embodiment, an outer diaphragm is not required. In an alternative embodiment, the flask 310 acts as an outer diaphragm. In various embodiments of the present invention, the system prevents contact between the gas and/or liquid 380 with air, prior to the gas and/or liquid being dispersed from the container flask system 300.

FIGS. 4A and 4B are schematic diagrams of cross-sectional views of a container flask system 400 where a gas or liquid 480 is stored inside an inner diaphragm 422 in the container flask system 400 and where pressing on the sides of the flask container system 400 forces the gas or the liquid 480 out of the container flask system 400. FIGS. 4A and 4B show a cross-section of a vacuum container flask system 400 with an outer diaphragm 440 connected with a hermetic seal to one or both the flask rim 370 and the flask 310 and an inner diaphragm 422 connected with a hermetic seal to the first one-way valve 450. Alternatively, the t one-way valve can be located at the spout exit 43 or anywhere along the spout 46 (in an alternative embodiment of the invention, a first one way conditional valve can be located at the exit of the container 450, and a probe can be inserted up the spout to activate the valve). The first one-way valve 450 allows liquid or gasses 480 to leave the inner diaphragm 422 only while air can enter the container flask system 300 through a second one way valve 430. The second one-way valve 430 can be located at the top of the container flask system 300 in the center of the outer diaphragm 440 or anywhere associated with the outer diaphragm 440. The liquid and/or gas 380 to be dispensed (or a solid which liquefies or sublimes) can be stored in the inner membrane 422. A delivery vent 488 that extends to the bottom of the container 489 can run up the side of the vacuum container flask system 300 and can be connected to the spout 486 through the opening 450. In an embodiment of the invention, an optional third valve can be used to control flow out of the opening 483.

In an embodiment of the invention, the liquid can be stored inside an inner diaphragm 422, which is contained inside a container flask system 400. Applying pressure to the container by squeezing the container 410 or pressing the outer diaphragm 440 either directly applies pressure to the inner diaphragm 422 or alternatively applies pressure by compressing the air in the container flask system 400 which then applies pressure to the inner diaphragm 422 to force the liquid 480 out of the inner diaphragm 422. When the pressure is withdrawn, air is allowed to travel inwards via the second one-way valve 430 (in only) to accommodate the volume of gas or liquid 480 that was expelled from the inner diaphragm 422. This can be done repetitively until the inner diaphragm 422 is completely empty and the air inside the container flask system 400 fills the volume of the container flask system 400. The first one-way valve 450 (out only) ensures that air cannot flow back into the inner diaphragm 422.

In FIG. 4A the inner diaphragm 422 has been significantly extended and the first compartment 480 is large. This would correspond with the situation before a significant amount of the container contents had been dispensed. In FIG. 4B the inner diaphragm 422 has been reduced and the first compartment 480 is small. This would correspond with the situation after a significant amount of the container contents had been dispensed.

In various embodiments of the invention, the one-way valves can be non-conditional. In an embodiment of the invention, the container flask system can be disposable, in which case it can be unopened and so the inner diaphragm is not released.

In various embodiments of the invention, the first, the second and/or the third conditional one-way valve can be replaced by a series of conditional one-way valves. In various embodiments of the invention, either the first, the second and/or the third conditional one-way valve can be replaced by a series of simple tube, where by closing the tube at an appropriate point in time the tube acts as a one way valve. In various embodiments of the invention, the container can be round or spherical. In other embodiments of the invention, the container rim and bottom can be round and the sides can be planar and contour to the shape of the rim and bottom. In various embodiments of the invention, the shape of the container can be elliptical or ovaloid. In other embodiments of the invention, the container rim and bottom can be an ellipse or an oval and the sides can be planar and contour to the shape of the rim and bottom. In various embodiments of the invention, the rim and bottom can be of equal dimension and the sides can vertically contour to the rim and bottom. In other embodiments of the invention, the rim can exceed the dimension of the bottom and the sides can be planar and adjust to the differing contours of the rim and bottom. In other embodiments of the invention, the bottom can exceed the dimension of the rim and the sides can be planar and adjust to the differing contours of the rim and bottom. In various embodiments of the invention, the container can be square, rectangular, trapezoid or any other shape.

In an embodiment of the present invention, the inner flexible diaphragm 322 can be made of multiple disposable layers that will enable reuse of a lid and diaphragm with a new inner diaphragm by simply discarding the old contaminated inner diaphragm 322. In an embodiment of the present invention, rims with the one or more inner diaphragms 322 can be designed for existing containers. In an alternative embodiment of the present invention, the product can be designed as a rim for existing containers or as a new container with a new rim.

In another embodiment of the present invention, the inner and outer diaphragms can be made as one organelle that will clip into a preexisting slot that is prepared on the rim. This may serve to simplify assembly and circumvent the use of glue or other adhesives that can be sensitive to high temperatures applied in the cleaning/washing process. In various embodiments of the present invention, the rim and container can be microwave-friendly. Since gasses can leave the container through the one or the one way valves, a simple microwave heating can result in the release of gasses rather than causing the lid to ‘pop off’ as happens with other sealed containers. In an embodiment of the invention, the temperature of the substance can be visualized by the position of the inner diaphragm while the food stored in the container is being heated.

In an embodiment of the invention, (see FIG. 3) when food needs to be stored the user will close the rim 370 and cause a force to be exerted on the outer diaphragm 340 one or more times. The two one-way valves 330 and 350 will create a simple pump that will suck out gasses around the food in the container and can bring the inner flexible diaphragm into contact with the stored food. In order to open the container 300, the user will release the vacuum via the conditional valve 330 and simply open the container. Subsequently, the conditional one-way valve 350 can be pressed to release the air pressure and flex the inner membrane back to its original position.

An advantage of the invention is that it allows storage of remaining food after a meal for better preservation either in 4° C. or at any other temperature. Alternately the container can be utilized to store food in the form of a lunch box or as carryout for take-away food, picnics, travel and catering. The container can also be used to store tissue samples and other liquids or gasses that can be sensitive to oxidation or excessive moisture. The container can be used to store food liquids such as juice, wine and milk to minimize the oxidation of the food liquid via air contact. The container can be used to store other liquids such as cell growth media and minimize the oxidation of the media via air contact. The container can also be used as a convenient method to store gasses to avoid mixing or dispersal of the gas with the atmosphere.

When food is to be stored in the refrigerator after a meal, a container just big enough to accommodate the food, but not too big, is advantageous so that the minimal amount of air is trapped with the food. However, this requires different size containers. Different size containers are not suitable for stacking and often result in clutter in a storage compartment or refrigerator. In an embodiment of the invention, a standard size container can be used to enable storage of food in vacuum conditions for better preservation and extension of shelf life under both a commercial as well as a domestic household setting. The base and rim and/or lid of the containers are made so that it is possible to stack one container on top of another to make best use of the space available for storage.

Pyrotechnic devices combine high reliability with very compact and efficient energy storage, in the form chemical energy which is converted to expanding hot gases either through deflagration or detonation. The controlled action of a pyrotechnic device (initiated by any of several means, including an electrical signal, optical signal or mechanical impetus) can initiate a wide range of automated and/or remote mechanical actions. For example, deployment of a pump to deliver a substance for safety equipment and services. The employment of a pump to deliver a substance for a precisely timed release sequences can also be controlled by a pyrotechnic device. In various embodiments of the invention, technical pyrotechnic devices use propellants in their function. In an embodiment of the invention, technical pyrotechnic devices use primary or secondary explosives to obtain very fast and powerful mechanical actions. In an embodiment of the invention, a pyrotechnic device uses propellants to obtain cutting actions.

In an embodiment of the invention, the force acting on the outer membrane can be generated by a mammal. In an alternative embodiment of the invention, the force acting on the outer membrane can be generated by a natural force. In another embodiment of the invention, the force acting on the outer membrane can be generated by a motor or a pyrotechnic device.

The inner diaphragm and the outer diaphragm form an organelle which can be releasably received in the inner circumference of the rim when the organelle can form a vacuum fit with the rim, which can subsequently be detached from the rim. In an embodiment of the present invention, the organelle can form a vacuum fit with the rim, which can subsequently be detached from the rim and then re-attached to the rim.

In an embodiment of the invention, a device for minimizing exposure of a substance to one or more reactants comprises a container, a rim and a first one-way conditional valve, wherein the substance is inserted into the container. The rim has a first perimeter, wherein when the rim is attached to the container the first perimeter of the rim forms a first vacuum seal with the container. The flexible inner diaphragm forms a second vacuum seal with the container, wherein two or more of the container, the rim and the inner diaphragm form a vacuum-sealed first compartment containing the substance. The first one-way conditional valve allows a gas containing the one or more reactants inside the first compartment to be displaced outside of the first compartment thereby adjusting the first compartment volume, wherein the flexible inner diaphragm changes to occupy the adjusted first compartment volume.

A storage system comprising a rim, wherein the rim has an inner circumference and an outer circumference, wherein the outer circumference forms a vacuum seal with a container. An inner diaphragm, wherein the inner diaphragm forms a vacuum seal with the inner circumference of the rim. A first one-way conditional valve which allows gas to pass from inside the container through the first one-way conditional valve out of the container, wherein when a force is applied to the inner diaphragm, air inside the container is forced out the first one-way conditional valve, thereby reducing the air in the storage system, wherein pressing the first one-way conditional valve allows air to pass from outside the container through the first one-way conditional valve into the container, thereby allowing the rim to be removed from the container and the storage system to be accessed.
