Definitions

  • Known plastic lidded containers for laboratory use have a tubular vessel having at the bottom a vessel bottom, at the top a vessel opening and below the vessel opening at the inside wall a sealing area.
  • a lid having a lid bottom and a stopper protruding from the inside of the lid bottom is insertable through the vessel opening into a sealing position in which the stopper seals at the sealing area.
  • the lid is held in the vessel by the clamping force of the plug.
  • a correspondingly high clamping force of the plug is required. To close and open the vessel, the user must spend a correspondingly high force.
  • plastic lidded containers which raise a special latching between the lid and the vessel in order to hold the lid in the sealing position on the vessel.
  • the EP 2 654 958 B1 describes a lidded container, which for easy and safe closing and easy opening a locking projection on the upper edge of the vessel and a protruding from the underside of the lid bottom elastic strap with a latching snap-in locking edge and one of the tab has laterally outwardly projecting button to cancel the locking of the locking edge with the locking projection.
  • EP 2 965 816 A1 protrudes from the tab, a first lever laterally outward and projects from the first lever at a distance from the tab, a second lever upwards to release the latch simply by pressing against the second lever.
  • the present invention seeks to provide a lidded container, which is better protected from contamination and handling friendly.
  • lidded vessel with the features of claim 1.
  • Advantageous embodiments of the lidded vessel are specified in subclaims.
  • the lid can be brought into a parking position in which the lid substantially or completely closes the container, without sealing in the sealing area.
  • the lid In the park position, the lid is held by the first latching means of the lidded vessel.
  • a relaxation of the plastic is avoided by tensions between sealing area and plug, which no longer allows sealing of the plug in the sealing area.
  • This ensures that the lidded vessel can later be closed in a sealing manner.
  • the lid is brought into the sealing position, in which the plug rests sealingly on the sealing area. The tensions between the sealing area and the plug are large enough to seal the lidded vessel.
  • a large number of lidded containers with the lid in parking position can be delivered in a bag. Since the lidded containers are closed, the risk of contamination, especially after removal from the bag is reduced. In addition, removed lidded containers can be labeled immediately on the top of the lid, since they are already closed. As in the park position voltages between plug and vessel are avoided as in the sealing position can be easier to open the lid after labeling for the filling of sample liquid than in conventional containers.
  • the plug engages in the parking position in a parking area on the inner wall of the vessel, which is arranged above the sealing area.
  • the parking position can be achieved by partially inserting the plug into the vessel. This simplifies the achievement of the parking position and the opening of the vessel.
  • the parking area is arranged on the inner wall of the vessel below the sealing area. In order to reach the parking position, the lid with the stopper must be inserted deeper into the vessel than to reach the sealing position.
  • the parking area is arranged above the sealing area and widens upwards. As a result, the insertion of the plug is facilitated in the parking area.
  • the parking area is conical.
  • the sealing region is a cylindrical or conical region on the inner wall of the vessel, against which the stopper sealingly abuts in the sealing position.
  • the sealing area is arranged concentrically to the central axis of the vessel, i. the central axis of the sealing area coincides with the central axis of the vessel.
  • the diameter of the conical region expands upwards or downwards.
  • the first latching device has a radially inwardly projecting first latching projection on the inner wall of the vessel.
  • first latching projection runs around at least a part of the circumference on the inner wall of the vessel.
  • the first latching projection is arranged above the parking area.
  • the first latching device on a radially outwardly projecting second latching projection on the outside of the plug.
  • the plug is with the second locking projection behind the first locking projection latched.
  • the lid is better secured in the parking position.
  • the second latching projection at least partially revolves around the plug.
  • the lid may be hinged to the vessel or a removable lid completely detachable from the vessel.
  • Another embodiment comprises a groove or groove circulating at least partially on the inner wall of the vessel and / or a bead circulating at least partially on the outside of the stopper.
  • the plug engages in the parking position with the bead in the groove or groove.
  • the groove has the function of a parking area.
  • the upper flank of the groove has the function of the first latching projection.
  • the bead has the function of the second locking projection.
  • the lower flank of the groove can prevent unintentional penetration of the plug into the sealing area.
  • the outer diameter of the bead is greater than the inner diameter of the vessel directly adjacent to the groove or groove.
  • the outer diameter of the bead is less than or equal to the inner diameter of the groove or groove.
  • the first locking projection or the groove or groove runs completely around the circumference on the inner wall of the vessel.
  • the first locking projection or the groove or groove is arranged on the inner wall of the vessel on the side opposite the hinge and does not completely run around the circumference on the inner wall of the vessel.

  • the first locking projection or the groove or groove on the opposite side of the hinge extends symmetrically on both sides of a vertical plane through the hinge and the central axis of the vessel.
  • the bead runs completely around the outside of the plug and the plug with the bead in the sealing position sealingly abuts the sealing region.
  • the bead additionally has the function of a sealing element. In the sealing position, the bead lies in a narrow, preferably linear, circumferential area on the sealing area, so that there is a high surface pressure, which causes a seal.
  • a second locking device for releasably locking the lid with the vessel in the sealing position.
  • the second latching device holds the lid in the sealing position on the vessel, so that in the sealing position only the required sealing between the plug and the sealing area must act. As a result, the forces to be applied by the user for closing and opening the lidded vessel can be reduced.
  • a second lever projects upwardly from the first lever at a distance from the tab.
  • the second lever facilitates the release of the locking of the lid with the vessel.
  • the second lever is provided with an outwardly projecting rib.
  • the rib can be used for opening and closing the lid by means of a working cone of a metering device or other tool.
