Definitions

  • the present invention relates to a disposable platform for energy applications, known as an energy application cartridge (EAC). More particularly, the present invention relates to a disposable gas cartridge and a method for manufacturing such cartridge.
  • EAC energy application cartridge
  • cartridges are available on the market. For example, cartridges are manufactured and marketed for a number of different applications such as soda streamers, paintball guns, etc. Such cartridges are usually in the form of a metal cylinder having a valve in one end, to which a regulator or activator may be connected.
  • an aluminum liner is drawn to a specified thickness and is hot-spun at its open end. Threads are provided on the inside of the open end for allowing a valve to be attached to the cartridge.
  • the aluminum liner is coated with an insulating layer and a carbon fiber material in an epoxy resin before a surface coating is applied.
  • Such cartridge is specified to withstand an internal pressure of 300 Bars, and is thus considered as a high pressure gas cartridge.
  • a further object of the present invention is to provide a gas cartridge which may be manufactured by a simple process, involving inexpensive and readily available materials.
  • a yet further object of the present invention is to provide a gas cartridge that may be recyclable.
  • a still further object of the present invention is to provide an EAC which can contain cooled liquid gas that after closing of the EAC container builds up pressure in room temperature or other temperature that is higher than the liquid gas boiling point.
  • An idea of the present invention is thus to create a cooling device or a dispenser of various substances.
  • a gas cartridge comprising a first tubular body having a closed end and an open end, and a second tubular body having a closed end and an open end.
  • the second tubular body is aligned with the first tubular body such that the closed end of the first tubular body is closing the open end of the second tubular body and vice versa, wherein the first tubular body has an area at its closed end, said area forming a penetrable membrane.
  • the open end of the second tubular body may be conforming to the shape of the closed end of the first tubular body. This is advantageous in that the second tubular body is prevented from moving relative to the first tubular body, thus creating an increase of the maximum internal pressure of the cartridge.
  • the second tubular body may comprise circumferential threads on its outer surface.
  • an external valve and/or opening mechanism may be connected to the cartridge.
  • the cartridge may further comprise an actuator, which upon operation penetrates said penetrable membrane.
  • the cartridge may further comprise a third tubular body being arranged within the first tubular body such that the closed end of the first tubular body is closing an open end of the third tubular body and vice versa. This is advantageous in that the cartridge may be easily designed for different applications requiring different pressure.
  • An adhesive may be arranged between the tubular bodies. Hence, the stability of the gas cartridge may be increased.
  • a method for providing a gas cartridge comprises the steps of: providing a first tubular body having a closed end and an open end, providing a second tubular body having a closed end and an open end, cooling said first and second tubular body to a predetermined temperature, filling the first tubular body to a certain extent with a liquid gas or solid content, wherein said predetermined temperature is below the boiling point of said gas or solid content, and closing said open end of the first tubular body by inserting the first tubular body into the second tubular body at said predetermined temperature whereby the closed end of the first tubular body is closing the open end of the second tubular body and vice versa.
  • the advantages of the first aspect are also applicable for the second aspect of the invention.

  • the gas cartridge comprises a first tubular body 20 having a closed end 22 and an open end 24.
  • the closed end has a spherical or dome shape and the first tubular body 20 has a wall thickness being substantially
  • the area 26 has a wall thickness which is substantially less than the rest of the wall of the first tubular body 20.
  • the first tubular body 20 is inserted into a second tubular body 30, which is shown in Fig. 2a and 2b.
  • the inner diameter of the second tubular body 30 is adopted to the outer diameter of the first tubular body 20 such that the first tubular body 20 is tightly fitted into the second tubular body 30.
  • the second tubular body 30 comprises a notch 38 that extends along the perimeter of the interior surface.
  • the notch 38 is thus defining a closed end 32 having a wall thickness which is greater than the thickness of the tubular wall of the second tubular body, including an open end 34.
  • the notch 38 is forming a stop such that the first tubular body 20 is prevented from moving further into the second tubular body 30.
  • the open end 34 of the second tubular body 30 is formed such that it conforms to the closed spherical end 22 of the first tubular body 20. However, a small opening is aligned with the membrane area 26 of the first tubular body 20.
  • the second tubular body 30 is further provided with threads 36 extending circumferentially on the exterior surface.
  • the wall thickness of the second tubular body 30 is disposed such that the closed end 32 has a thickness that substantially corresponds to the sum of the wall thicknesses of the first and the second tubular bodies 20, 30 at a position beyond the notch 38. Consequently, the gas cartridge has a wall thickness which is uniform except for the membrane area 26.
  • the gas cartridge 100 has a first, second, and third tubular body 200, 300, 400 which are forming a multi-layer cartridge similar to what has been described with reference to Fig. 1 and Fig. 2a-b.
  • the first tubular body 200 is inserted into the second tubular body 300, and the third tubular body 400 is arranged inside the first tubular body 200 in the same manner as shown in Fig. 1, wherein the first tubular body 20 is inserted in the second tubular body 30.
  • the third and the first tubular bodies 400, 200 are engageable in the same manner as the first and the second tubular bodies 20, 30 of Fig. 1, except for the fact that the membrane area 260 of the embodiment in Fig. 3 is provided on the first tubular body 200, i.e. the tubular body comprising the notch 280.
  • the two-layer cartridge 10 of Fig. 1 and the three-layer cartridge of Fig. 3 may be opened by penetrating the membrane area 26, 260 of the cartridge 10, 100.
  • Such opening mechanism may be implemented in accordance with an actuator as shown in Fig. 4.
  • the gas cartridge may have four or more tubular bodies of similar or different materials such as Al, carbon fibre, alloys thereof, etc creating a cartridge being suitable for different applications requiring different properties of the cartridge, wherein the pressure stability of the cartridge is dependent on the number and thicknesses of the tubular bodies as well as on the materials of the tubular bodies.
  • a cartridge 500 similar to the gas cartridge 10 of Fig. 1, has a cap 550 attached to one of its ends.
  • the cap 550 has internal threads which are engaged with the threads 536 of the gas cartridge 500.
  • a needle When the cap 550 is tightened by rotating, a needle will be moved towards the membrane area 526 and the membrane area 526 will eventually be penetrated such that the enclosed gas is allowed to escape out of the cartridge.
  • the cap 550 may be sealed against the cartridge by an O-ring 552. Further, exhaust channels 554 may be provided for allowing the gas to escape of the cap.
  • the cap 550 may further be provided with a connector (not shown) for allowing the cap 550 to be connected to a regulating valve.
  • the cap may be operated by a pressing motion instead of a rotating motion.
  • a method 1000 for providing a pressurized fluid or/and gas cartridge will be described with reference to Fig. 5.
  • a first tubular body is formed having a closed end and an open end.
  • the tubular body may be formed in any way known per se, preferably by extruding a metal blank into said body.

Description

SAHLSTROM EQUITY AB
AN ENERGY APPLICATION CARTRIDGE
FIELD OF THE INVENTION
The present invention relates to a disposable platform for energy applications, known as an energy application cartridge (EAC). More particularly, the present invention relates to a disposable gas cartridge and a method for manufacturing such cartridge.
PRIOR ART
A number of gas cartridges are available on the market. For example, cartridges are manufactured and marketed for a number of different applications such as soda streamers, paintball guns, etc. Such cartridges are usually in the form of a metal cylinder having a valve in one end, to which a regulator or activator may be connected.
According to one manufacturing method, an aluminum liner is drawn to a specified thickness and is hot-spun at its open end. Threads are provided on the inside of the open end for allowing a valve to be attached to the cartridge. Following this step, the aluminum liner is coated with an insulating layer and a carbon fiber material in an epoxy resin before a surface coating is applied. Such cartridge is specified to withstand an internal pressure of 300 Bars, and is thus considered as a high pressure gas cartridge.
Due to the complex manufacturing process, including many different materials and process steps, such gas cartridges are expensive and thus often used as refillable products. Consequently, the use of such cartridges is not suitable for certain disposable applications where price and availability are crucial factors.
There is thus a need for an improved high pressure gas cartridge.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a disposable EAC in the form of a high pressure gas cartridge.
A further object of the present invention is to provide a gas cartridge which may be manufactured by a simple process, involving inexpensive and readily available materials.
A yet further object of the present invention is to provide a gas cartridge that may be recyclable. A still further object of the present invention is to provide an EAC which can contain cooled liquid gas that after closing of the EAC container builds up pressure in room temperature or other temperature that is higher than the liquid gas boiling point.
An idea of the present invention is thus to create a cooling device or a dispenser of various substances.
According to a first aspect, a gas cartridge is provided. The gas cartridge comprises a first tubular body having a closed end and an open end, and a second tubular body having a closed end and an open end. The second tubular body is aligned with the first tubular body such that the closed end of the first tubular body is closing the open end of the second tubular body and vice versa, wherein the first tubular body has an area at its closed end, said area forming a penetrable membrane.
The open end of the second tubular body may be conforming to the shape of the closed end of the first tubular body. This is advantageous in that the second tubular body is prevented from moving relative to the first tubular body, thus creating an increase of the maximum internal pressure of the cartridge.
The second tubular body may comprise circumferential threads on its outer surface. Hence, an external valve and/or opening mechanism may be connected to the cartridge. The cartridge may further comprise an actuator, which upon operation penetrates said penetrable membrane.
The cartridge may further comprise a third tubular body being arranged within the first tubular body such that the closed end of the first tubular body is closing an open end of the third tubular body and vice versa. This is advantageous in that the cartridge may be easily designed for different applications requiring different pressure.
An adhesive may be arranged between the tubular bodies. Hence, the stability of the gas cartridge may be increased.
According to a further aspect, a method for providing a gas cartridge is provided. The method comprises the steps of: providing a first tubular body having a closed end and an open end, providing a second tubular body having a closed end and an open end, cooling said first and second tubular body to a predetermined temperature, filling the first tubular body to a certain extent with a liquid gas or solid content, wherein said predetermined temperature is below the boiling point of said gas or solid content, and closing said open end of the first tubular body by inserting the first tubular body into the second tubular body at said predetermined temperature whereby the closed end of the first tubular body is closing the open end of the second tubular body and vice versa. The advantages of the first aspect are also applicable for the second aspect of the invention.

Fig. 6 is a schematic cross sectional view of a dispensing unit having a gas cartridge according to an embodiment. DESCRIPTION OF EMBODIMENTS
With reference to Fig. 1, Fig 2a, and Fig 2b, a gas cartridge 10 according to an embodiment will be described. The gas cartridge comprises a first tubular body 20 having a closed end 22 and an open end 24. The closed end has a spherical or dome shape and the first tubular body 20 has a wall thickness being substantially
homogeneous except for an area 26 positioned at the center of the closed end 22. The area 26 has a wall thickness which is substantially less than the rest of the wall of the first tubular body 20.
The first tubular body 20 is inserted into a second tubular body 30, which is shown in Fig. 2a and 2b. The inner diameter of the second tubular body 30 is adopted to the outer diameter of the first tubular body 20 such that the first tubular body 20 is tightly fitted into the second tubular body 30. The second tubular body 30 comprises a notch 38 that extends along the perimeter of the interior surface. The notch 38 is thus defining a closed end 32 having a wall thickness which is greater than the thickness of the tubular wall of the second tubular body, including an open end 34. The notch 38 is forming a stop such that the first tubular body 20 is prevented from moving further into the second tubular body 30.
The open end 34 of the second tubular body 30 is formed such that it conforms to the closed spherical end 22 of the first tubular body 20. However, a small opening is aligned with the membrane area 26 of the first tubular body 20.
The second tubular body 30 is further provided with threads 36 extending circumferentially on the exterior surface.
The wall thickness of the second tubular body 30 is disposed such that the closed end 32 has a thickness that substantially corresponds to the sum of the wall thicknesses of the first and the second tubular bodies 20, 30 at a position beyond the notch 38. Consequently, the gas cartridge has a wall thickness which is uniform except for the membrane area 26.
With reference to Fig. 3 a gas cartridge 100 according to a further embodiment is shown. The gas cartridge 100 has a first, second, and third tubular body 200, 300, 400 which are forming a multi-layer cartridge similar to what has been described with reference to Fig. 1 and Fig. 2a-b.
The first tubular body 200 is inserted into the second tubular body 300, and the third tubular body 400 is arranged inside the first tubular body 200 in the same manner as shown in Fig. 1, wherein the first tubular body 20 is inserted in the second tubular body 30. Hence, the third and the first tubular bodies 400, 200 are engageable in the same manner as the first and the second tubular bodies 20, 30 of Fig. 1, except for the fact that the membrane area 260 of the embodiment in Fig. 3 is provided on the first tubular body 200, i.e. the tubular body comprising the notch 280.
The two-layer cartridge 10 of Fig. 1 and the three-layer cartridge of Fig. 3 may be opened by penetrating the membrane area 26, 260 of the cartridge 10, 100. Such opening mechanism may be implemented in accordance with an actuator as shown in Fig. 4.
In a further embodiment, the gas cartridge may have four or more tubular bodies of similar or different materials such as Al, carbon fibre, alloys thereof, etc creating a cartridge being suitable for different applications requiring different properties of the cartridge, wherein the pressure stability of the cartridge is dependent on the number and thicknesses of the tubular bodies as well as on the materials of the tubular bodies.
A cartridge 500, similar to the gas cartridge 10 of Fig. 1, has a cap 550 attached to one of its ends. The cap 550 has internal threads which are engaged with the threads 536 of the gas cartridge 500. When the cap 550 is tightened by rotating, a needle will be moved towards the membrane area 526 and the membrane area 526 will eventually be penetrated such that the enclosed gas is allowed to escape out of the cartridge.
The cap 550 may be sealed against the cartridge by an O-ring 552. Further, exhaust channels 554 may be provided for allowing the gas to escape of the cap.
The cap 550 may further be provided with a connector (not shown) for allowing the cap 550 to be connected to a regulating valve.
In another embodiment, the cap may be operated by a pressing motion instead of a rotating motion.
In the following, a method 1000 for providing a pressurized fluid or/and gas cartridge will be described with reference to Fig. 5. In a first step 1010, a first tubular body is formed having a closed end and an open end. The tubular body may be formed in any way known per se, preferably by extruding a metal blank into said body.
The closed end may have a spherical or dome shape, and the central point of the spherically shaped bottom end may be provided with a membrane area having a smaller wall thickness than the rest of the tubular body.
In a further embodiment, the closed ends may be substantially planar such that the closed ends are arranged perpendicular to the longitudinal axis of the cartridge. In a yet further embodiment, the closed ends may be partly dome shaped and partly planar.
For example, the wall thickness of the tubular body may be greater than 0,3 mm, and the thickness of the membrane area of the spherically shaped bottom end may be less than 0,3 mm, preferably between 0,1 and 0,2 mm. The diameter of the central area of the spherically shaped end may be approximately 1 mm. In addition to these proportions, the outer diameter of the tubular body may in one example be 20,6 mm.
In a next step 1020, a second tubular body is formed having a closed end and an open end. The second tubular body may be formed in any way known per se, preferably by the same process as used when forming the first tubular body, e.g. by extruding a metal blank into said body. The closed end may have a spherical shape wherein the spherical portion has a greater wall thickness than the rest of the tubular body. The spherical bottom end may be provided with an annular notch, such that the increased wall thickness is provided as an immediate increase of wall thickness.
For example, the wall thickness of the second tubular body may be 0,7 mm, and the thickness of the spherically or dome shaped bottom end may be 1 ,0 mm. In addition to these proportions, the inner diameter of the second tubular body may be 20,6 mm or just above. In a following step 1030 the first tubular body is cooled down to a
predetermined temperature, preferably by introducing said tubular body into a cooled chamber. When the tubular body is cooled down to said predetermined temperature, the tubular body is filled to a certain amount by liquid gas, or other content, for example solid content such as dry ice etc.
The gas may be C02, and the predetermined temperature may be a temperature being below the boiling point of C02. If C02 is used in atmospheric pressure, the predetermined temperature may be -80°C.
In a following step 1040, the second tubular body is brought onto the first tubular body, having the open ends of the tubular bodies facing each other. During this step, the interior volume of the second tubular body may be exposed to an over-pressure of the same gas as being contained within the first tubular body, for avoiding entrapment of air. Preferably, this step is performed in the same cooled chamber as used when filling the first tubular body.
As an optional step 1035, an adhesive may be coated on the outer surface of the first tubular body, on the inside of the second tubular body, or both. When the second tubular body is slidably fitted onto the first tubular body, the annular notch will form a stop position and it will prevent the first tubular body to protrude any further into the second tubular body.
During the step 1040, the open end of the second tubular body may be formed to seal tightly against the spherical end of the first tubular body. Hence, the open end of the second tubular body will conform to the spherical end of the first tubular body. In a preferred embodiment, the open end of the second tubular body will conform to the spherical end of the first tubular body but leaving an opening at the same position as the membrane area of the first tubular body.
When the adhesive has formed a strong bonding between the first and the second tubular body, the formed cartridge may be moved outside the cooled chamber during a step 1050 and thus be allowed to heat up until room temperature is reached. Upon this, the pressure inside the cartridge will increase and consequently further improve the sealing properties between the first and the second tubular body.
In a specific embodiment, the open end of the first tubular body may have a spherical shape, although it is left open by means of a through hole. Preferably, the diameter of the through hole may be between 1 and 10 mm. In such case, the annular notch of the interior surface of the closed end of the second tubular body may be arranged to fill the space formed by the through hole. The method 1000 may further comprise additional steps 1060, 1070 in which further tubular bodies are provided and arranged onto each other for forming multi-layer gas cartridges in accordance with what has been described previously with reference to Fig. 3.
The first and the second tubular bodies may for example be made of Al, or any alloy containing Al. In further embodiments other metal based compounds may be used, or suitable carbon fiber materials.
In the following, a number of different gas cartridge applications will be described.
Example 1 : Cooling insert for PET bottles.
The gas cartridge is filled with high pressure carbon dioxide. The end of the cartridge having the membrane area is arranged within a cylinder shaped support of a double threaded cap. The cap is further attached to the open end of a PET bottle enclosing liquid food, such as a soft drink. The functionality of the cap allows for penetration of the membrane area if the cap is rotated in a first direction. The
penetration is provided by means of a needle which is pushed through the membrane area upon rotation of the cap. Carbon dioxide will thus be allowed to escape, and the cartridge will upon this be cooled down to the boiling point of carbon dioxide. Hence, the enclosed product will be cooled down by the escape of the carbon dioxide. The cap may further be provided with a locking mechanism that prevents the cap from being removed from the bottle at a moment before the gas cartridge is completely emptied. Hence, accidents due to the low temperature may be avoided.
Example 2: Cooling insert for portable medical storage systems.
A portable medical storage system comprises a box having storage room for medical equipment and/or substances. Further, the box encloses a regulating system for ensuring a stabilized interior temperature. The regulating system includes a cooling source, a valve, and at least one sensor.
A gas cartridge is securely attached to an electrical valve and the membrane area is penetrated when the cartridge is attached to the valve. The valve is further connected to a sensor system that continuously measures the temperature inside the box. If the temperature is increasing above a predetermined threshold level, the sensors will transmit a signal to the valve which will open and compressed C02 will be exhausted. Consequently, the temperature inside the box will be lowered. In a further embodiment, the regulating system comprises an alert functionality which notifies a user when it is time to change the gas cartridge.
The box may be provided with insulating inserts for controlling the
temperature distribution within the box.
Example 3: Gas cartridge as an aerosol container/dispenser
An aerosol container 600 is shown in Fig. 6. A gas cartridge 610 is arranged in a housing 620. The housing 620 has a bottom inlet 622 into which the gas cartridge 610 is inserted. Upon insertion, a needle 632 of a valve 630 is penetrating the membrane area of the gas cartridge 610. The gas cartridge 610 is further sealed against a gasket, and the inlet 622 is sealed and closed for preventing gas to leak out. The gas cartridge is filled with a liquid product and a propellant, such that aerosols are dispensed when the valve 630 is opened. The product may e.g. be perfume, deodorants, cosmetics, medicals, oils, and/or other substances.
The present invention has been described above with reference to specific embodiments. However, other embodiments than the above described are equally possible within the scope of the invention. The invention is only limited by the appended claims.
