Definitions

  • the present invention relates to a method and a system for pressurising and dispensing fluid products stored in a bottle, can, container or similar device.
  • Fluid products such as liquids, pastes, gels, foams and the like are often stored in sealed and pressurized containers such as cans.
  • Such pressurized containers typically have a dispensing device for allowing a controlled dispensation of the fluid product.
  • the dispensing device includes a dispensing valve which is normally in a closed non-dispensing position preventing any fluid product from leaving the container.
  • the dispensing valve may selectively by user interaction be temporarily switched to an open dispensation position allowing the fluid product to advance from an inner space inside the container towards the outside of the container.
  • the fluid product should be dispensed in an aerosol state or spray state.
  • the valve may preferably be of the well known "atomizer" type described in e.g. US 1,800,156 .
  • Fluid product which are preferably dispensed in the form of an aerosol include hairspray, spray-paint and insect repellent.
  • the pressurized container typically including a propellant gas subjecting the fluid product to a driving pressure for causing the product to flow out of the container through the dispensing device provided the valve is in its open position.
  • the inner space of the pressurized container is divided into a pressure space, typically forming a head space of the container and including the propellant gas, and a product space including the fluid product.
  • the dispensing device must include an ascending pipe for allowing the fluid product to be dispensed from the bottom of the container and avoiding propellant gas escaping from the pressure space at the top of the container.
  • the pressure space and the product space may be physically separated by a flexible membrane as described above. For economical reasons the pressure space should be as small as possible for allowing small containers to be manufactures having a large amount of useful product.
  • the volume of the product space is being reduced. While dispensing, the product space is being substituted by the pressure space which thus will increase in volume.
  • the driving pressure which is the pressure inside the pressure space, will be reduced as the volume of the pressure space increases, provided the amount of gas and the temperature remains constant.
  • a sufficient driving pressure must still remain when the product is completed.
  • the smallest sufficient driving pressure is contemplated to be between 0.1 bar above the atmospheric pressure for a substantially non-viscous product up to 1 bar or more depending on the properties of the fluid product which is intended to be dispensed.
  • the initially high driving pressure will sink significantly when some amount of the product has been dispensed due to the volume increase of the pressure space.
  • a large difference in the driving pressure during the lifetime of the product is undesired, since the initial dose of product will be dispensed at a high driving pressure and the final dose of product will be dispensed at a low driving pressure.
  • the difference in driving pressures between a container being full of product compared to a container where the product is nearly completed yields an entirely different dispensing behaviour for the initial dose of product and the final dose of product.
  • An unexpectedly high driving pressure may surprise some users and cause an excessive amount product to be dispensed, while a low driving pressure may cause a slow dispensation of the product thereby extending the dispensation time.
  • the successful usage of the product depends entirely on the driving pressure, e.g. sprays and foams typically need a specific driving pressure for a correct spray/foam formation and the application of the product may be complicated in case the actual driving pressure varies from the specific driving pressure. It is therefore a need for technologies for maintaining a substantially constant dispensing pressure during the complete useful lifetime of the dispenser assembly.
  • the driving pressure is below the limit for allowing dispensing before the product is completed.
  • the limit for allowing dispensation may be different for different products, but it is contemplated that the driving pressure must remain between 0.1 and 2 bar, typically 0.5 bar, above the atmospheric pressure for overcoming the flow resistance in the dispensing device and achieving a suitable dispensing performance.
  • the user has no possibility of re-pressurising the pressure space since the container is sealed and cannot be opened without the use of professional tools.
  • the dispensing operation must be interrupted and the user will typically have to consider the remaining product as being unrecoverable.
  • a well known example of improper handling of the container is, in case the container have a unitary inner space, i.e. no separation between the pressure space and the product space, to place the container upside down, thereby dispensing from the pressure space instead of from the beverage space. Such dispensation position may deplete the propellant gas within a short time, rendering the remaining product inaccessible. It is thus an object of the present invention to provide a product dispenser assembly capable of substituting the complete product space by the pressure space while maintaining a substantially constant driving pressure.
  • an intrinsic pressure limitation mechanism is preferred.
  • An example of an intrinsic pressure limiter is presented in US 2006/0049215 where a gas-adsorbing material is used as a reserve gas supply.
  • the gas-adsorbing material may store a large amount of gas within a small volume.
  • the gas is being released from the gas-adsorbing material in response to a driving pressure decrease in the container.
  • the gas-adsorbing material is being wetted with a release-promoting agent for allowing improved release of gas.
  • the gas adsorbing material of the above technology will thus be able to react on and compensate for a pressure decrease in the container by releasing previously stored gas.
  • the amount of product being dispensed and the dispensing velocity may be excessive, since the driving pressure in the pressure space is much higher than it would be at room temperature.
  • a self regulating and constant pressure maintaining product dispenser assembly comprising a dispensing device and a product container, the product container defining an inner space, the inner space comprising:
  • Carbonated beverages include various types of sparkling beverages having a certain amount of CO 2 (carbon dioxide) dissolved in the aqueous content of the beverage.
  • the exact amount of CO 2 may differ between different kinds of carbonated beverage.
  • the pressure space may typically be filled with CO 2 as propellant gas. Loss of carbonisation resulting from e.g. extended time periods of storage in-between servings may cause the carbonated beverage to become flat and less tasty.
  • the CO 2 dissolved in the carbonated beverage form a pressure equilibrium with the CO 2 in the pressure space and the CO 2 in the adsorption material.
  • the propellant gas is CO 2 and direct contact between the product space and the pressure space is permitted, the driving pressure must correspond to the carbonisation level of the beverage.
  • the container defines an inner space for accommodating the fluid product.
  • the product space is understood to be the portion of the inner space in which the fluid product is stored and typically occupies the greater part of the inner space.
  • the pressure space should subject the product space to a driving pressure for allowing the fluid product to the propelled to the outside via the dispensing device.
  • a particular amount of adsorption material which is sufficient for adsorbing a specific amount of propellant gas sufficient for substituting the complete product space without any significant loss of the initial driving pressure is provided in the pressure space.
  • the driving pressure is understood to be the pressure difference between the pressure space and the outside.
  • a certain minimum driving pressure is needed for dispensing the fluid product.
  • the adsorption material should have an inherent capability of both adsorbing and releasing propellant gas depending on the pressure in the pressure space. A reduction of the driving pressure in the pressure space will be immediately counteracted by an inherent release of propellant gas from the adsorption material for substantially neutralizing the pressure reduction and maintaining the initial pressure.
  • a certain loss of driving pressure in the pressure space is unavoidable during the complete dispensation of the fluid product.
  • the pressure loss is inherently depending on the particular amount of adsorption material.
  • constant driving pressure it may be considered to provide a large amount of adsorption material for storing a larger amount of propellant gas for the loss of driving pressure to be low and the driving pressure to be considered to be substantially maintained.
  • propellant gas should be stored in the adsorption material for the purpose of compensating for leakage which may become relevant during long time storage.
  • Some products, such as fire-extinguishing products, may be stored for years in-between each dispensing operation, however, such products must always maintain a sufficient driving pressure for allowing immediate user selective dispensation of the product when required.
  • the pressure space will increase and the product space will reduce according to the amount of dispensed product until the product space is depleted and the total amount of product has been dispensed.
  • the pressure should remain at least above the minimum dispensing pressure at all times until the product has been dispensed. It is further contemplated that product dispensation should be performed having the beverage container in a correct orientation, since the total amount of propellant gas may be quickly depleted in case of improper orientation of the product container, e.g. by holding the product container in an upside down orientation.
  • a driving pressure of 0.1-3 bar above the outside pressure would not be sufficient for substituting the product space and completing the product, assuming a small pressure space in relation to the product space.
  • the driving pressure falls below the minimum dispensation pressure, the dispensing operation is interrupted and the residual product will be lost.
  • the driving pressure may be held substantially constant at the initial pressure of 0.1-3bar, or at least not fall below 0.1 bar, until the complete product space is depleted and substituted by the pressure space.
  • the pressure in the pressure space would quickly reduce and the dispensation operations would end due to lack of driving pressure before the product has been completed.
  • the particular amount of adsorption material and the specific amount of gas should be sufficient for substituting the complete product space, without leaving any residual product when the driving pressure and the outside pressure have equalized.
  • the pressure of a given gas volume varies with temperature.
  • Most commercial fluid products are intended to be dispensed at temperatures around room temperature and the driving pressure of the propellant gas in the pressure space of a typical product dispenser assembly is adjusted to be suitable for dispensing operations in room temperature.
  • the product container will be exhibited to temperatures being different from room temperature and the temperature may be both higher and lower than the room temperature.
  • a higher temperature in the pressure space will cause the driving pressure to increase while a lower temperature will cause a reduction in driving pressure.
  • the product dispenser assembly may be exhibited to temperatures between 0°C and 90°C, or at least 3°C and 50°C, during normal operating conditions.
  • a rise in driving pressure resulting from subjecting the product container to high temperatures is a well known phenomenon among users of pressurized containers and may lead to high dispensing velocity and/or an undesired dispensing behaviour and/or spillage.
  • a reduction in driving pressure resulting from subjecting the product container to low temperatures is equally well known among users of pressurized containers and may lead to slow dispensing velocity which may sometimes cause the product user to falsely believe that the fluid product is completed.
  • the adsorption material will counteract the pressure variation by releasing some propellant gas and thereby maintaining the pressure.
  • the particular amount of adsorption material is able to compensate for an increase of the driving pressure caused by e.g. a temperature raise in the pressure space by re-adsorbing the excessive propellant gas. It is an inherent feature of the adsorption material to be able to both release (desorb) and adsorb propellant gas. Since the pressure may vary in both directions, i.e.
  • the adsorption material is capable of releasing propellant gas in case of temperature reduction and re-adsorbing propellant gas in case of a temperature increase, thereby compensating for temperature dependent variations of the driving pressure in the pressure space for maintaining a substantially constant driving pressure over a broad temperature range.
  • the adsorption material will constantly regulates the driving pressure in the pressure space by inherently releasing and re-adsorption of propellant gas in reaction to pressure variation without any of the propellant gas being lost. Since the pressure maintaining feature of the adsorption material is inherent and involves no moving parts, the risk of malfunction is minimal.
  • the adsorption material For the adsorption material to work properly, it is necessary to keep it in a dry state. Any fluid product or other fluid substance contacting the adsorption material may be accidentally absorbed by the adsorption material. Such accidentally adsorbed substances may reduce the ability of the adsorbing material to adsorb and release propellant gas. Therefore, the adsorbing material should preferably be subjected to propellant gas only.
  • the pressure space having an initial pressure of no more than 2 bar above the atmospheric pressure, preferably no more than 1.5 bar above the atmospheric pressure, more preferably no more than 1 bar above the atmospheric pressure and most preferably no more than 0.5 bar above the atmospheric pressure.
  • a smaller initial pressure is typically preferred for achieving a suitable dispensing velocity and avoiding over-dispensation of the product and allowing a suitable dispensing behaviour.
  • the initial pressure in pressure space and canister can be maintained low without the need for having a very high pressure in the pressure and adsorbing material for allowing a complete substitution of the product space.
  • maintaining a lower driving pressure requires a significantly smaller amount of adsorption material than maintaining a higher driving pressure.
  • the pressure space after the complete substitution of the product space by the pressure space, having a pressure above the atmospheric pressure amounting to at least 60% of the initial pressure, preferably at least 70% of the initial pressure, more preferably at least 80% of the initial pressure and most preferably at least 90% of the initial pressure.
  • a certain pressure loss in the pressure space is unavoidable, since maintaining 100% of the initial driving pressure over the lifetime of the product would require an infinite amount of adsorption material.
  • the driving pressure must not be significantly reduced for maintaining good dispensing properties.
  • the pressure should be maintained until the product competed, or at least for an extended time period which may be comparable to the maximum storage time of the product, such as least a few months and more preferably a few years or more, depending on the kind of product.
  • the driving pressure it is contemplated that at least 60%, preferably at least 70%, more preferably at least 80% and most preferably at least 90% of the initial pressure remains after the product has been completed. Thereby, the last amount of product being dispensed just before the product is completed will be dispensed with substantially the same dispensing behaviour and quality as the initial dispensed product amount.
  • the product space initially occupying at least 70% of the inner space, preferably 75%, more preferably 80% and most preferably 85%.
  • the pressure space is a part of the inner space of the product container which does not contribute to the payload, i.e. the storing of the product, and may thus be considered a waste since the product container must be manufactured and transported having a larger inner space than actually needed for the product space.
  • an efficient adsorbing material capable of storing the specific amount of propellant gas needed to substitute the product space within a small volume the pressure space may be smaller, since initially the main purpose of the pressure space is for accommodating adsorption material.
  • a reduction of the amount of adsorption material may be achieved by having a sufficiently low initial driving pressure as discussed above.
  • the pressure space should initially not occupy more than 30% of the inner space of the product container, leaving 70% of the inner space for the product space.
  • the product space initially occupies an even larger portion of the inner space and the pressure space a corresponding smaller portion.
  • the adsorption material inherently adsorbs propellant gas when the product container is being heated above the specific temperature range for avoiding any substantial increase of the pressure in the pressure space.
  • the product container may be heated above the specific temperature range, e.g. above 50°C or above 90°. Such heating may occur accidental, e.g. due to fire, incoming solar radiation or warm climate, but also intentional, e.g. during disposal by combustion. In such cases the pressure will rise in the inner space. In typical product containers the pressure may rise to several tens of bar during heating until the structural limit of the container is reached and the container ruptures. Such ruptures may in some cases be explosive and damage to persons and/or property cannot be excluded.
  • the pressure rise in the inner space will in the present case be counteracted by an increased adsorption of propellant gas by the adsorption material, thus by providing a suitable amount of adsorption material any substantial pressure increase may be avoided even when the product container is subjected to high temperatures.
  • a product dispenser assembly being able to withstand high temperatures, such as temperatures exceeding 50°C, e.g. 100°C, 200°C or even 500°C without a significant pressure increase may thus be regarded as being explosion proof, which is an important safety feature.
  • the container may be safely disposed by combustion while experiencing only a minor pressure increase without any explosive rupture of the product container..
  • the product space and the pressure space are being separated by a flexible and fluid tight wall preventing any fluid communication between the pressure space and the product space during the complete dispensation of the product.
  • the inner space may in some cases be compartmentalized by e.g. a flexible inner wall or bag delimiting the product space from the pressure space and a flexible or preferably rigid outer container defining the inner volume and the pressure space being defined between the inner bag and the outer container.
  • a flexible inner wall or bag delimiting the product space from the pressure space and a flexible or preferably rigid outer container defining the inner volume and the pressure space being defined between the inner bag and the outer container.
  • Such technologies are well known from e.g. bag-in-box and bag-in-container concepts and are suitable in case the propellant gas should not be in contact with the product, such as in case the propellant gas is toxic or reacting with the product.
  • the product will become carbonated in case the propellant gas comes into direct contact with the product, which may be undesired for e.g. body lotions etc.
  • the ascending pipe may be omitted when using a flexible wall.
  • Flexible wall should in the present context be understood to encompass deformable walls, elastic walls and movable walls.
  • it may even be desired to separate the pressure space by having a separate compartment for storing the adhesive material. Such separate compartment may even be located outside the container and communicating with the proper pressure space via a tube. Concerning some other products, such as e.g. shaving foam and aerosol products, the inner space must be unitary for allowing the product to mix with the propellant gas for the foam or aerosol to be established.
  • the mass of the particular amount of adsorbing material amounts to approximately 1%-10%, preferably 2%-5%, more preferably 3%-4%, of the initial mass of the product in the product space. It is preferred to use as small amounts of adsorbing material as possible since the adsorbing material does not contribute to storing beverage and may thus be considered a waste since a larger beverage dispensing assembly must be manufactured and transported to the customer. On the other hand, a large amount of adsorption material will allow smaller pressure variations and ensure a substantially constant pressure being maintained in the inner space from the initial dispensing operation until the product is completed.
  • the adsorption material comprise activated carbon.
  • activated carbon is used as the adsorption material, since it may adsorb and release sufficient large amounts of CO 2 for permitting a small pressure space in relation to the product space.
  • Activated carbon also adsorbs and releases CO 2 sufficiently fast for allowing a continuous dispensation of product and a quick response to changing of the temperature and pressure inside the product container.
  • the propellant gas is chosen from among: CO 2 , N 2 , any of the noble gases such as He, Ne or Ar, any of the hydrocarbons such as propane, butane, isobutene, dimethylether, methyl, ethyl ether, or hydrofluoroalkanes, or a mixture of the above.

  • the purpose of the hydrophobic wall 199 is to eliminate the use of a hydrophobic membrane by making the complete outer wall of the canister hydrophobic, liquid impermeable but gas permeable for keeping the adsorbing material dry.
  • the canister 122 should be made having a specific density smaller than the product for at least partially floating at the product surface.
  • the portion of the hydrophobic wall remaining above the product surface will communicate with the pressure space and the adsorbing material in the inner chamber 178 of the canister 102"' may release CO 2 to pressure space 144 as well as adsorb CO 2 from the pressure space 144.
  • the portion of the hydrophobic wall 199 being submerged below the surface of the product will act as a seal and prevent any product from entering the inner chamber 178.
  • the benefit of the present embodiment is the very simple design of the canister 102"'.
  • Fig 8 shows yet an alternative embodiment of a product dispensing assembly 10 VI according to the present invention.
  • the present product container 112' resembles the product container described in connection with fig 3 , however the canister is being omitted and the adsorption material 186 is being contained within a flexible bag 170 at the bottom of the product container 112.
  • the product container 112' defines a pressure space 144' within the flexible bag 170 containing the adsorption material 186 and a product space 142'.
  • the pressure space 144' and the product space 142' are separated by the flexible bag 170, which is made of flexible and/or elastic material.
  • the flexible bag 170 encapsulates the pressure space 144' and separates the pressure space 144' from the inner space of the container 112'.
  • the product hose 126 is attached to the base part 146 for fluid communication with the product space 142', however the product hose 126 does not include any ascending pipe extending into the product space 142'.
  • the present embodiment lacks a pressure space in form of a head space, since the pressure space 144' is separated from the product space 142' by the flexible bag 176'. The pressure space 144' will subject the product space 142' to a driving pressure.
  • Fig 10 shows an alternative embodiment of a product dispensing assembly 10 VII according to the present invention.
  • the present embodiment features a substantially cylindrical product container 112' including a product space 142' at the lower portion of the product container 112' and a pressure space 144' at the upper portion of the product container 112'.
  • the pressure space 144' and the product space 142" are separated by a moving wall 184.
  • the pressure space 144' includes adsorption material 178 being stored at the bottom of the container 112'.
