Definitions

  • the invention relates to a container with a pressure compensation device consisting of a container body, a container lid and at least one closure element consisting essentially of a threaded bolt, by means of which the container lid can be fixed on the container body.
  • a burst protection for tanks is known from CH-A-558 462, which has a guide part in the interior of the tank for guiding a guide pin which can be displaced parallel to the side walls.
  • the cover of the tank is firmly connected to the guide pin and is pressed against the sealing edge of the side walls by a spring arranged on the guide pin.
  • Such a burst protection has the disadvantage that the tank in question requires a special design in the interior to accommodate the displaceable guide pin. This requires relatively high manufacturing costs for both the tank and the one arranged inside Burst protection.
  • Spring safety valves are known as a further possibility for burst protection. These work on the principle that a sealing cone is raised against the force of a spring. There are different designs here, which differ in the articulation of the sealing cone or its kinematics. In the known spring safety valves, the valve is opened in that the internal pressure and the force per area associated therewith overcomes the counterpressure of the spring which presses the sealing cone into its seat.
  • this principle has the disadvantage that such safety valves are more or less directly connected to the ingredients, especially if the structural conditions do not permit any other solution. If the valves of this type are used, for example, in special waste containers, they must be mounted on the lid of the respective container in order to enable proper functioning.
  • the spring safety valves also have the disadvantage that they are very susceptible to contamination. Another disadvantage is that they are complex to build and are therefore very expensive to purchase if they are to work in small printing areas. Furthermore, if a container is retrofitted accordingly, it often has to be structurally changed.
  • rupture disks Another known system for avoiding internal pressures is the so-called rupture disks. These rupture disks consist of a membrane with a much thinner material than other system parts. If there is now a negative pressure or positive pressure in the container, the membrane deforms in such a way that it bursts when a previously defined pressure is exceeded. Since even slight corrosion effects, which are insignificant for other components, would lead to premature bursting in the case of a rupture disc, these are always made of corrosion-resistant Materials such as Monell, tantalum or VA steel are made. The disadvantage of this system is that the rupture discs are destroyed after a single response. In addition, the rupture of such a rupture disc, for example during transport of the container, can result in the material contained in the container being able to escape.
  • the two systems described last have the disadvantages in the field of explosion protection and pressure protection that structurally often only a relatively small opening cross-section is available to compensate for atmospheric pressure and that only a small, pressurized area as an actuator for the corresponding Pressure compensation device is available.
  • the solution according to the invention consists in that the support element is articulated or engages on the outside on the container body or on the container lid.
  • the threaded bolt that can be screwed to the cover for example, is connected to the outside of the container body via a spring. If an overpressure builds up in the interior of the container that exceeds the spring force, the threaded bolt moves relative to the support element, so that the container lid lifts off the edge of the container body against the spring force, pressure equalization taking place until the spring force is again greater than the internal pressure of the internal atmosphere of the container acting on the container lid.
  • a container can be provided with a pressure compensation device without having to make complex structural changes to the container itself. This makes it possible to provide an inexpensive pressure compensation device for containers.
  • the support element can consist of a U-shaped bracket, the free ends of which are pivoted on a bolt arranged on the container body.
  • the threaded bolt can be pivoted into a slot on the cover-side tab and can be fixed there via the nut.
  • a lock nut or a plurality of lock nuts can be screwed onto the threaded bolt in such a way that the tab can be clamped between them and the nut. This ensures that the spring is not over-tensioned by tightening the nut when closing the container lid.
  • the spring can advantageously be a plate spring.
  • a plurality of threaded bolts can be arranged uniformly distributed over the circumference of the container lid.
  • the container lid can also be pivoted on the opening edge of the container body via a swivel joint.
  • a sealing rubber is advantageously arranged in the container lid, which is pressed into the edge of the container body when the container lid is closed.
  • the invention further relates to a closure element according to claim 8 for use in a container of the type described above.
  • This closure element consists of a threaded bolt which is supported via its head part against a spring which is arranged in a support element.
  • This closure element can be used in conventional pressure containers without further structural changes to these containers in order to convert them into containers with a pressure compensation device.
  • the container 10 comprises a container lid 14 which is placed on a container body, not shown in detail in FIG. 1, preferably a waste container body.
  • the container body is designated by 12 in FIG.
  • the container body 12 has a welded-on edge 38, to which a container lid 14 is articulated by means of a swivel joint 44 known per se.
  • the container lid 14 will be fixed to the container body 12 via six threaded bolts 16 uniformly distributed over the circumference and wing nuts 24 cooperating with them.
  • a U-shaped bracket 22 forming a support element is pivotally connected to the container body 12 via a bolt 40 via a U-shaped holder 42.
  • a plate spring 20 is arranged in the support element 23, at the free end of which a head 18 of the threaded bolt 16 is supported.
  • the threaded bolt 16 is inserted in the manner shown in Figure 2 through a corresponding hole in the support member 22.
  • two lock nuts 30 and 32 are screwed, which are secured against each other via a tack point 34.
  • the threaded bolt is in a slot 26 on the container lid 14 welded-on tab 28 can be swiveled in.
  • the lock nuts 30 and 32 or a washer resting thereon bear directly against the tab 28 from below.
  • the wing nut 24, which comes to rest on the tab 28, is screwed onto the free end of the threaded bolt 16.
  • a sealing rubber 36 provided in the container lid 14 is pressed onto the edge 38 of the container body 12 (see FIG. 2). If the wing nut 24 of the respective container closure is loosened, the entire container closure can be pivoted about the pivot axis 40. The cover 14 can then be opened by pivoting about the articulation axis 44.
  • the cover 14 presses against the force of the plate spring 20 via the tab 28 and the threaded bolt 16 Force on the lid is greater than force opposed by the spring 20 or a plurality of springs 20, the lid 14 is raised slightly. This creates a gap between the container edge 38 and the sealing rubber 36, so that pressure equalization with the surrounding atmosphere is made possible. As soon as the excess pressure is released, the lid lowers again.
  • the pressure point with which the lid is raised can be adjusted by turning the lock nut 30 or 32.
  • it can be set to an opening pressure of 0.3 to 0.5 bar.
