Definitions
- the invention relates to a container which is filled with liquid and sealed pressure-tight and can be removed from the liquid.
- containers are Fasser, Kleinanker (Partylase) or cans in which CO 2 -containing liquids, especially drinks, are filled under pressure. It's all about party-gatherers for beer.
- the container according to the prior art EP 1 642 861 A1 has an insert which can be sealed in an opening of the container and has a C0 2 high-pressure cartridge, a pressure regulating valve for emitting CO 2 therefrom and an externally accessible actuator, by the operation of the C0 2 -Hochdruckpatrone let pierce.
- C0 2 cartridges in a size suitable for large containers contain approx. 16 g of CO 2 under a pressure of approx. 60 bar.
- the pressure regulator of EP 1 642 861 Al reduces and precisely regulates the pressure under which the in the headspace of the container spent CO 2 is.
- the pressure is typically between 0.7 and 1.3 bar. It is equal to or slightly higher than the partial pressure of CO 2 dissolved in the liquid.
- the present invention deals with the per se unlikely Storfall that the pressure control valve according to EP 1 642 861 Al for whatever reason fails. Then it can come slowly, but also very quickly to an uncontrolled increase in pressure in the container.
- a conventional party keg for beer withstand an internal pressure up to about 6.5 bar. From about 4 bar cambered the party keg; Topsoil and / or underbody of the party barrel bulge up. At about 6.5 bar burst the party keg, and usually by the fact that a folded seam between the coat and the topsoil or the bottom of the party keg rises. The remaining CO 2 escapes.
- the party keg runs out, possibly with a powerful Fontane beer. people are not endangered by this, but damage to property is possible, and there is a lot of clean-up work.
- a container with a built-in pressure system which has a C0 2 -Hochdruckpatrone, a pressure control valve for outputting CO 2 thereof and an externally accessible actuator, by the operation of the C0 2 -Hochtikpatrone is pierced ,
- the pressure system has an overpressure safety device which, in the event of an undesired pressure increase in the container, releases a flow path from its head space through the pressure system to the atmosphere.
- the overpressure protection according to EP 1 688 813 A1 consists of a pressure relief valve which has a valve member in the form of an overpressure hose stump and blocks or releases a complicated flow path via a plurality of openings, bores and channels.
- the structural complexity and the cost price of such an overpressure protection are high.
- the object of the invention is to provide a container of the type mentioned with an overpressure protection, which is inexpensive and reliable in construction and signaled to the customer in Storfall that something is wrong with the owner's own printing system.
- the overpressure protection loosens this task bursts after exceeding an internal pressure, in which the container visibly cambered, but before reaching an internal pressure at which the container bursts.
- the bursting part of the overpressure protection is a membrane on the wall of a housing, with which the insert protrudes into the container.
- the Stromungsweg leads for blowing off the CO 2 via a leak in the actuator.
- the overpressure protection is ineffective before piercing the C0 2 -Hochdruckpatrone.
- the overpressure protection is activated by the piercing of the C0 2 high pressure cartridge. This ensures that the excess pressure only comes into function when it is actually needed, namely in a failure of the pressure control valve.
- the overpressure protection bursts at an internal pressure between 4.0 bar and 9.0 bar, preferably 4.5 bar to 7.0 bar, more preferably 5.0 to 6.0 bar.
- the membrane truncates before piercing the C0 2 -Hochdruckpatrone on the actuator.
- the membrane of the actuator is released.
- the membrane is recessed in the insert. It is thus protected from damage.
- the membrane is made of elastic plastic. With an uncontrolled increase in internal pressure, the membrane experiences increasing elastic deformation until it bursts.
- Fig. 1 is a CO 2 -Druckgas provoke in longitudinal section; and FIG. 2 shows the elastic plastic component of a detail II of FIG. 1.
- the source of CO 2 compressed gas is designed as an insert which fits through the bunghole of a container into the container and tightly closes the bunghole.
- the container is filled with CO 2 -containing liquid under pressure through the bunghole usually located in the middle of its topsoil. Then the bunghole is closed with the insert.
- the liquid passes through internal pressure and gravity effect, until in the headspace of the Behalters above the Flusstechnikspegels therein a negative pressure is reached.
- the CO 2 compressed gas source is activated.
- the CO 2 compressed gas source feeds CO 2 at a pressure into the headspace of the container, which corresponds to the partial pressure of dissolved in the liquid CO 2 or slightly exceeds this partial pressure. This ensures a constant emptying of the container. There is no air in the headroom of the container.
- the CO 2 content of the liquid remains the same.
- the insert is of elongated-slender shape and mostly radially symmetric to a central axis. It consists mainly of plastic.
- the two-component plastic injection molding technique offers.
- the insert which is in the installed position and closes the bunghole of the container, protrudes into the container with a housing 10.
- the housing 10 has at its inner end a chamber 12 for the snug-fit recording of a CO 2 high-pressure cartridge 14.
- the housing 10 is seated outside with a circumferential collar 16 on the Bordelrand of the bunghole. At the collar 16, a seal 18 is formed, with which the insert seals the bunghole. About the collar 16 is in front of a recessed into the housing 10 knob 20, upon actuation of the CO 2 cartridge 14 is pierced.
- the knob 20 has a steep external thread 22, with which it is screwed into a complementary internal thread of the housing 10.
- a piercing needle 24 For piercing the C0 2 cartridge 14 is a piercing needle 24, which is structurally associated with the valve member of a pressure control valve.
- the valve member is suspended with an elastic membrane 26 in the axial center of the housing 10.
- the tip of the piercing needle 24 is only slightly spaced from the end face of the CO 2 cartridge 14.
- valve seat 28 is formed from the elastic Dichtmate ⁇ al to the housing 10.
- the piercing needle 24 is acted upon by a slider 30 which is located between the knob 20 and the piercing needle 24.
- the slider 30 is guided slowly displaceable in the housing 10. When actuated, the knob 20 screws against the slide 30, which is axially displaced.
- a helical compression spring 32 is clamped between the knob 20 and slider 30, a helical compression spring 32 is clamped.
- the helical compression spring 32 biases the slider 30 against the piercing needle 24.
- the membrane 26 defines a working space downstream of the valve seat 28 of the pressure regulating valve.
- the working space has a lateral Auslmud- opening, in front of an elastic sealing ring 34 is located.
- the sealing ring 34 has the function of a check valve. It prevents liquid from entering the insert.
- the knob 20 is rotated by about 90 ° ge ⁇ .
- the slider 30 is adjusted by the screw feed of the knob 20 axially inwards.
- the piercing needle 24 is carried along with elastic deformation of the membrane 26 axially inwards.
- the Ven Tilglied lifts from the valve seat 28. After piercing, a very small valve space in front of the head of the C0 2 cartridge 14 fills with CO 2 under high pressure.
- the slider 30 After completed 90 ° rotation or Uberfitung the knob 20, the slider 30 jumps against the force of the helical compression spring 32 axially outward. He is to be actuated by the Anlegeadel 24, which is reset by the elastic jerk deformation of the diaphragm 26 axially. The helical compression spring 32 is tensioned. The pressure control valve is closed and a small amount of high pressure CO 2 admitted into the working space. The CO 2 - compressive forces on the membrane 26 contribute to the pressure-actuated jerking of the slide 30 at.
- the further opening and closing of the pressure regulating valve is determined by an equilibrium of forces on the diaphragm 26, to which the elastic properties of the diaphragm 26, the spring constant of the helical compression spring 32 and the CO 2 pressure in the working space contribute.
- the spring constant of the helical compression spring 32 is determining.
- the user will activate the source of CO 2 compressed gas when the internal pressure in the container has dropped to the point where the jet of liquid exiting through the drain cock becomes too weak.
- the source of CO 2 compressed gas can readily be activated beforehand even if the internal pressure in the container is still high, very likely even at the user's first user intervention on the container.
- a metering of CO 2 in the headspace of the Behalter does not take place as long as the high internal pressure on the sealing ring 34 in front of the Auslowingo réelle loaded.
- the CO 2 gas source is provided with an overpressure fuse which becomes effective when the pressure control valve fails and CO 2 passes into the head space of the container under unkon ⁇ trolled high pressure.
- thermoplastic elastomer TPE is injection-molded on the wall of the housing 10 close to the bunghole, the lot of least material thickness of which forms a membrane 36 buried in the wall.
- the membrane 36 is connected to the outer surface of the piercing of the CO 2 - cartridge 14 not yet actuated knob 20 in flush arrangement. It is placed between two adjacent threads of the external thread 22 on the knob 20.
