Definitions

  • the present invention relates to a rotation mechanism for sealing transport containers for liquids.
  • a clamping ring used for sealing transport containers is disclosed in the form of a lid for a pot in EP 1 215 138 B1, in which a pressure release device is provided on the lid and a locking ring fits around the lip of the pot for substantially creating a seal with the pot.
  • a part of a securing mechanism extends horizontally from the pressure release device, and a bolt pointing downwards is provided on the end of the securing mechanism, wherein the bolt is received by an aperture in the clamping ring.
  • This securing mechanism and others like it can have various shortcomings.
  • the securing mechanism can become deformed, and it can be difficult to take apart the pressure release valve or the securing mechanism. Furthermore, in such a case it is necessary to replace the valve and the securing means, which is associated with considerable costs.
  • a system and method for securing a cover onto a container including a visual verification that the cover is secured.
  • a retaining mechanism is provided which prevents the cover from being inadvertently lifted from the container, more specifically, from being rotated when in the locked position.
  • Another embodiment of the invention provides a securing assembly for ensuring that the retaining mechanism cannot be inadvertently removed from the cover unless the securing assembly is disassembled or broken. A user is thus visually alerted to the risk, ensuring that the user either replace the securing assembly or take necessary precautions while handling the container.
  • a retaining mechanism comprises a projection that engages a corresponding cavity or aperture in a cover, a container with which the cover creates a seal when in the locked position, and a latching ring, which maintains the cover in place on the container.
  • the object of the invention under consideration is therefore to create a more reliable and economical system for securing a cover by latching a clamping ring than presently available.
  • a further object of the invention is to provide a system for securing a cover by latching a clamping ring that is easy to use, that can be assembled and disassembled relatively simply.
  • the invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the apparatus embodying features of construction, combination (s) of elements and arrangement of parts which are adapted to effect such steps, all as exemplified in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
  • FIG. 1 is a front elevational cross-sectional view of a container and cover in accordance with an embodiment of the invention
  • FIG. 2 is a partial view of a cover, fastener and retaining mechanism in accordance with an embodiment of the invention
  • FIG. 3 a is a partial view of a cover and fastener in accordance with an embodiment of the invention.
  • FIG. 3 b is a perspective view of a retaining mechanism in accordance with an embodiment of the invention.
  • FIG. 4 is a partial cross sectional view of a container, cover, fastener and retaining mechanism in accordance with an embodiment of the invention.
  • a fastener such as a clamping ring
  • a fastener secures the cover in place and helps create a seal between the cover and the container. It is preferable for a seal to be created to prevent leakage, especially if the container is filled with liquid.
  • the clamping ring covers the seal formed between the cover and the container, thus protecting it and helping to prevent it from being broken.
  • FIG. 1 is an illustrative depiction of a container generally indicated as 1 in which liquids can be held.
  • Container 1 preferably has an outlet (not shown) proximate its lower end or on the lower area of the sidewall.
  • container 1 is suitable for being transported.
  • container 1 can have castors 8 as shown.
  • container 1 can be transported using forklifts or the like, rather than being rolled.
  • Container 1 can thus be formed as a transport container.
  • container 1 comprises a tank 2 , which has an opening generally indicated as 4 proximate its upper end. Opening 4 can provide access to the interior of the tank 2 , for example, for maintenance work, cleaning or the like. It is common for opening 4 to be called a “manhole”.
  • opening 4 At least during transport, it is preferable for container 1 and thus opening 4 to be closed, more preferably sealed, to prevent the contents of container 1 from spilling or leaking out of container 1 .
  • a cover 3 can be placed on container 1 to close opening 4 .
  • Cover 3 is preferably placed on a seal 6 , which can facilitate sealing cover 3 and container 2 .
  • a fastener 5 can be provided to apply pressure on cover 3 onto container 1 to keep cover 3 in place with respect to container 1 and can also shield cover 3 and container 2 where they meet.
  • FIG. 2 wherein a portion of cover 3 and faster 5 is shown with gas outlet 7 and a retainer 10 are shown.
  • Retainer 10 preferably prevents fastener 5 from being shifted out of place, and preferably, from being inadvertently released from container 1 .
  • fastener 5 is placed on container 1 so that a notch generally indicated at 12 of fastener 5 receives a pin 13 of container 1 .
  • fastener 5 which can either be connected to or be independent from cover 3 , is preferably rotated, thus permitting pin 13 to enter a channel generally indicated at 12 a of notch 12 .
  • fastener 5 once fastener 5 is in this locked position, neither fastener 5 nor cover 3 can be removed simply by pulling at it. Rather, fastener 5 must be rotated until pin 13 is no longer within channel 12 a of notch 12 before fastener 5 and cover 3 can be pulled away from container 1 .
  • retainer 10 comprises a projection 11 which can be inserted into a corresponding aperture in fastener 5 .
  • container 1 has a corresponding aperture or cavity for receiving projection 11 . Therefore, when projection 11 is received by fastener 5 and container 1 , fastener 5 is substantially prevented from rotating or shifting, thus preventing the inadvertent release of pin 13 from notch 12 .
  • Notches 12 and pin 13 interact in such a way that fastener 5 can be rotated into a latching position in which cover 3 sits firmly on container 1 or a position in which fastener 5 , preferably together with cover 3 , can be removed from container 1 .
  • the interaction of projection 11 and fastener 5 and container 1 , more preferably also with cover 3 substantially prevents rotation of fastener 5 , unless projection 11 has been removed.
  • Cover 3 preferably includes a gas outlet 7 .
  • Gas outlet 7 is preferably constructed and arranged to relieve excess pressure in container 1 , or to limit the amount of excess pressure in container 1 .
  • gas outlet valve 7 can release gas from within container 1 when a predetermined pressure is reached.
  • retainer 10 extends toward gas outlet 7 as shown in FIG. 2 .
  • retainer 10 has a first leg 10 a having projection 11 , first leg 10 a extending substantially parallel to cover 3 a second leg 10 b extending away from cover 3 , and a third leg 10 c having an aperture generally indicated at 19 .
  • Aperture 19 preferably can receive at least a portion of gas outlet 7 .
  • FIGS. 2 and 4 when retainer 10 is properly positioned to retain fastener 5 and cover 3 in place with respect to container 1 , projection 11 is received by container 1 and third leg 10 c is positioned such that gas outlet 7 is at least partially received within aperture 19 .
  • gas outlet 7 comprises a hollow housing 40 and includes a plug assembly 14 therewithin.
  • Plug assembly 14 preferably comprises a plug 22 which can substantially seal a gas aperture 25 in container 1 .
  • top 30 exerts a pressure on a spring 23 and thus plugs 22 toward container 1 to close gas aperture 25 .
  • plug 22 can be pushed outward in order to permit gas to exit container 1 .
  • Gas outlet 7 preferably comprises one or more openings 26 , more preferably proximate cover 3 . The gas escaping from container 1 can thus exit through the one or more openings 26 to relieve the pressure within container 1 .
  • plug 22 preferably substantially seals gas aperture 25 again. It is to be understood that whereas a spring 23 is preferred, for example, because it permits the movement of plug 22 without requiring the movement of a top 30 of plug assembly 14 , this selective movement can be provided in a variety of ways without the use of a spring.
  • Top 30 preferably includes one or more protrusions 15
  • gas outlet 7 preferably comprises one or more top notches generally indicated at 16 .
  • plug assembly 14 is inserted into housing 40 of gas outlet 7 until protrusions 15 are received by top notches 16 , whereupon top 30 is rotated until protrusions 15 are sufficiently within top-notch channel 16 a.
  • top 30 is substantially prevented from being removed from gas outlet 7 by merely pulling it. Rather, top 30 must be rotated and then pulled in order to be removed from gas outlet 7 .
  • protrusions 15 and top notch 16 provide an additional benefit. It can prevent the removal of retainer 10 . Once retainer 10 is positioned so that gas outlet 7 is received within aperture 19 and projection 11 is sufficiently received by container 1 , protrusions 15 , which extend outwardly from gas outlet 7 , can prevent the removal of retainer 10 .
  • a bolt 31 provides an additional reassurance as well as a visible indicator that retainer 10 is properly in place.
  • top 30 has a groove 28 .
  • groove 28 aligns with one or more bolt apertures 27 of gas outlet 7 . Therefore, once retainer 10 and plug assembly 14 are properly positioned, bolt 31 can be slid through a first bolt aperture 27 , through groove 28 and through a second bolt aperture 27 , such that bolt 31 is located within groove 28 with a portion of bolt 31 extending outward from gas outlet 7 .
  • top 30 can be prevented from being rotated unless bolt 31 is removed or broken. This can thus substantially prevent the removal of retainer 10 as long as container 1 is still under pressure.
  • groove 28 can be preferable because it can prevent top 31 from being rotated to release protrusion 15 , it is not necessary.
  • bolt 31 can be positioned above top 30 , thus preventing top 31 from being removed without removing or damaging bolt 31 .
  • certain embodiments of the invention provide assurance that container 1 is properly closed, and a confirmation of the authenticity of the seal between cover 3 and container 1 , thus substantially preventing accidental opening and spilling of the contents of container 1 .
  • gas outlet 7 is illustrated as being cylindrical and extending substantially perpendicularly from cover 3 , it is to be understood that gas outlet 7 can take other forms, such any extending at an acute or obtuse angle, being cubical, curved, etc., without deviating from the scope of the invention. Additionally, aperture 19 can be a different shape, for example, rectangular, oval, etc. without deviating from the scope of the invention.
  • FIG. 4 illustrates an embodiment of cover 3 and fastener 5 secured to container 1 , wherein retainer 10 prevents cover 3 from being removed from container 1 .
  • the embodiment of container 1 has a flange 20 that extends around opening 4 .
  • a seal 21 lies on flange 20 , and as shown, fastener 5 and cover 3 are pressed on to seal 21 .
  • fastener 5 , cover 3 and flange 20 have apertures preferably aligned and suitable for receiving projection 11 .
  • Projection 11 of retainer 10 can be inserted through these apertures to prevent fastener 5 from being rotated about container 1 .
  • Projection 11 is preferably covered by first leg 10 a of retainer 10 , which can protect projection 11 from becoming deformed.
  • first leg 10 a extends substantially parallel to cover 3 until it meets second leg 10 b at a substantially 90 degree angle, which then meets third leg 10 c at a substantially 90 degree angle.
  • the connections between second leg 10 b and first leg 10 a and/or third leg 10 c need not be at substantially 90 degrees, but can be an acute or obtuse angle. Alternatively, the connection can be gradual, rather than at a defined angle.
  • the connection between first leg 10 a and second leg 10 b can be recessed from cover 3 and first leg 10 a can extend away from cover 3 , which may facilitate assembly.
  • first, second and/or third leg 10 a, 10 b, 10 c can be curved rather than straight as shown in FIGS. 2 and 3 b, and can be separate pieces rather than one integral piece.
  • Top 30 is then rotated to release protrusions 15 from top notch 16 .
  • Gas outlet 7 is thus made non-functional or is opened completely.
  • the pressure exerted by spring 23 against plug 22 is thus removed, and therefore plug 22 retracts away from gas aperture 25 .
  • Any excess pressure in container 1 is consequently relieved, and the interior of container 1 is thus at ambient pressure.
  • retainer 10 can be pulled away from cover 3 until it is released from gas outlet 7 .
  • projection 11 is also pulled out of the apertures of fastener 5 , cover 3 and flange 20 until projection 11 fastener 5 is released.
  • fastener 5 can be rotated to release pin 13 from notch 12 , after which fastener and thus cover 3 can be removed from container 1 .
  • the invention can be particularly advantageous for transport containers in which the persons who fill the containers are not the ones who empty the containers. The latter are thus often not familiar with all the technical details of the transport containers. Therefore, a transport container that prevents faulty operation, such as opening the manhole when the container is under pressure, as provided in accordance with an embodiment of the invention, can be advantageous.
  • the examples provided herein are merely exemplary, as a matter of application specific to design choice, and should not be construed to limit the scope of the invention in any way.
  • retainer 10 can also facilitate replacement of retainer 10 should the need arise. For example, if retainer 10 becomes deformed, or broken, etc., a new retainer can simply be used and the unusable retainer discarded. This can also reduce maintenance cost by permitting partial replacement rather than the replacement of the entire cover or container.
  • retainer 10 is preferably formed of a substantially resilient material that is substantially resistant to deformation, chipping, cracking, etc.
