Definitions

  • the invention relates to a lidded plastic container for laboratory use.
  • Lidded vessels of the type mentioned typically have a capacity of a few tens of milliliters or a few milliliters or a milliliter or less.
  • 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 the sealing area.
  • the lid is sealed and held by the clamping force of the plug in the vessel.
  • a sample liquid filled in the vessel is heated and has an increased vapor pressure.
  • PCR Polymerase Chain Reaction
  • samples in lidded vessels are repeatedly heated to temperatures above 90 ° C.
  • the clamping force of the plug shall be such that adequate steam tightness is ensured and the lid does not release under the increased steam pressure.
  • a high force is required to press the lid with the stopper into the vessel.
  • the user To open the lid, the user must press firmly against the lower edge of a protruding edge of the lid bottom.
  • a lidded vessel of the type described above is known, are connected to the vessel and lid via a hinge hinge integrally pivotable with each other.
  • the lid has a locking hook projecting downwardly from a laterally projecting lid flange and the vessel next to the vessel opening in the closed position of the locking hook behind engaged locking cam on.
  • When closing the lid of the rigid locking hook snaps under elastic deformation of the cover flange behind the locking cam, whereby the lid is secured in the closed position.
  • the user To open the lid, the user must push up the lid flange so that it is bent upwards and the locking hook is released from the locking cam.
  • locking hook and locking cam only a small overlap.
  • the locking hook can unintentionally release from the locking cam, for example, when the internal pressure in the vessel increases.
  • the locking hook can jerky release from the Veiriegelungsnocken, which liquid sample can be sprayed from the vessel.
  • the lidded container has a support device which stabilizes the lid in an intermediate position between a starting position pivoted away from the vessel opening by approximately 180 ° and a closed position at the vessel opening.
  • two parallel fork tines extend between the hinge straps from the vessel flange, between which a gap parallel to the hinge straps is formed.
  • the forks have locking edges.
  • a detent nose is aligned, which is connected at its tip with the cover flange and has locking projections on both sides of its root.
  • the locking lug is lined with their locking projections perpendicular to the cover flange. If the lid is closed in the direction of the vessel opening, then the latching nose enters into the gap between the fork tines and presses them slightly apart with their latching projections. When the locking projections come under the locking edges of the forks, they snap something together.
  • the support device has a latching nose, which is designed as a towering from the plane of the vessel flange hook.
  • the locking lug is arranged between flexible middle portions of two parallel hinge bands, which are connected at one end to the vessel flange and the other end to the cover flange.
  • the cover flange has a locking edge aligned perpendicular to its pivoting plane between the hinge straps.
  • the lid is pivoted further and snapped with the locking hook behind the locking cam.
  • This is disadvantageous that the achievement of the intermediate position can be hampered by the flexibility of the hinge straps. For example, if the user pushes against the outer edge of the cover flange when swiveling from above, he shifts the cover downwards due to the flexibility of the hinge straps. As a result, the locking edge meets at a low point on the locking lug and can only be pressed with great effort on the end of the locking lug.
  • a disadvantage of both embodiments is that the stability of the open position of the lid depends on the elasticity of the band sections. If the elasticity decreases, for example as a result of multiple closing and opening of the lid or due to heating or cooling of the vessel, the lid may become unintentional move out of the predetermined intermediate position and completely or partially close the vessel opening. This can affect the filling and emptying of the lidded vessel.
  • two parallel hinge bands are also arranged between the vessel flange and the cover flange, the flexibility of which is essentially concentrated on the narrowly limited area of a pivot axis.
  • Vessel flange and cover flange are connected by another hinge strap, which is arranged between the hinge straps.
  • the further hinge has one joint to the vessel flange at one end and a hinge to the cover flange at the other end. Between these two joints, it is relatively thin, so that it is elastically extensible. After injection molding the lidded container, the lid is angled at about 180 ° from the vessel opening. In this starting position, the further hinge band is not stretched.
  • a disadvantage of this lidded container is that because of the narrowly defined region of the pivoting axis, the hinge straps do not permit any compensating movement during insertion of the inventive sealing collar into the vessel opening. As a result, the closing of the lid is difficult. In the embodiments with flexible middle portions of the hinge bands, however, allow the flexible middle portions a compensation, which facilitates the coaxial insertion of the sealing collar into the vessel.
  • the EP 1 731 443 A1 describes a reaction vessel with a lid, which can be opened by a lever mechanism.
  • the lever must be pressed from above. As a result, it can lead to incorrect operation, for example, when lidded vessels are removed from a fully loaded centrifuge or from a fully loaded container stand. Furthermore, the plug of the lid is kept short, so that the vessel has a low vapor-tightness. If the stopper were to be extended, the lever would need to be extended to provide easy opening, further increasing the risk of misuse.
  • the US 3,934,722 describes a package for sterile needles with a lid that can be opened via a lever mechanism.
  • a lever is articulated via a film hinge, which can be placed with its inner lever arm on a vessel flange.
  • the plug of the lid is levered out of the vessel.
  • the lid is secured in the closed position only by the clamping force of the plug in the vessel.
  • the lever is used exclusively for opening the vessel.
  • the US 5,270,011 describes a reaction vessel with a lid, which is held by a securing device consisting of a bending tab and a locking pin in the closed position.
  • a securing device consisting of a bending tab and a locking pin in the closed position.
  • the bending and snapping of the bending tab Over the locking pin is cumbersome and usually requires the use of both hands. Likewise, the release of the safety device.
  • the US 5,674,456 describes a substantially rectangular container for medical samples with a lid that can be closed or opened via a snap closure.
  • the closure is attached to the front of the lid. It has a vertical, two-armed lever which is centrally connected to the edge of the lid.
  • the lower lever arm has a hook, which engages in the closed state of the lid a projection on the edge of the vessel.
  • the upper lever arm is provided with an outwardly projecting button. By pressing against the button from below the hook from the detent position under the locking projection can be lifted. The button is exposed so that incorrect operation is easily possible.
  • the US 6,398,067 B1 describes a tamper-resistant lidded container in which the vessel has at the top of a detachable projection having a hook and a break point.
  • a lid has a hinge and a tab having first and second slots capable of receiving the projection.
  • the second slot has a locking device.
  • the projection In the empty and closed state of the container, the projection is arranged in the first slot.
  • the protrusion In a filled and closed state, the protrusion is located in the second slot and the hook engages a latch to form a tamper resistant closure.
  • To open the lid the user must press with a sufficient force from below against the tab, so that the detachable projection breaks off at its breaking point.
  • a disadvantage is the high force required to release the closure and thereby incurred as waste detachable projection.
  • the WO 95/13137 A1 describes a lidded container with a safety catch which is actuated by turning the lid with respect to the vessel. To open the lidded container, the lid must be rotated in the opposite direction with respect to the vessel and then pulled out of the vessel with the stopper. This requires two-handed operation.
  • the DE 3402276 C1 describes a reaction vessel made of plastic for small quantities of liquid with a lid arranged integrally by means of a flexible flat web arranged on the opening and an outwardly projecting edge which comes in the closed state over a substantial peripheral portion with the opening edge of the vessel in abutment.
  • the cover has an insertable into the opening, cylindrical wall portion from which the outwardly projecting edge extends in a flange, and at its end to be inserted into the opening, a sealing lip is arranged outside.

  • Closing and opening can be done with just one hand. A sufficient safety against automatic opening need not be realized by a larger overlap or clamping force between sealing plug and vessel. The associated higher closing and opening forces are avoided.
  • the plug can sit in the sealing position with a relatively low clamping force. This clamping force can be measured so that a sufficient vapor-tightness is ensured. Due to the low clamping force, the lid can be easily lifted after loosening the catch, without the lid suddenly jumping up and liquid being spilled or aerosols escaping.

  • the lidded vessel 1.1 is in the in Fig. 6 and 7 shown, opened arrangement produced by injection molding. Due to the shape free of undercuts, the lidded vessel 1.1 can be produced by means of a simple injection molding tool without slides, the tool parts of which must be moved apart for removal from the mold only along an axis.
  • the lid 11 can by swiveling out of the in Fig. 6 and 7 closed opening position are closed.
  • the user presses against the outside of the lid bottom 12.
  • the lid 11 In an intermediate position according to Fig. 8 and 9 the lid 11 by constraining the shoulders 15.1, 15.2 in the locking receptacles 16.1, 16.2 can be locked.
  • the deflection of the shoulders 15.1, 15.2 laterally outward and backward by the flexibility of the shoulders 15.1, 15.2 and strip areas 14.12, 14.22 allows.
  • the shoulders 15.1, 15.2 reach the area of the latching receptacles 16.1, 16.2, they enter the latching receptacles 16.1, 16.2 due to the elasticity of the shoulders 15.1, 15.2 and the strip areas 14.12, 14.22.
  • the shoulders engage in the receiving edges 16.11, 16.21 and the lid 11 is held in this holding position by the elasticity of the hinge bands 14.1, 14.2.
  • the shoulders 15.1, 15.2 emerge at the top from the openings of the locking receptacles 16.1, 16.2 and do not collide with the receiving edges 16.12, 16.22.
  • the Receiving edges 16.12, 16.22 can alternatively be arranged so that they are in the swivel range of the shoulders 15.1, 15.2 and the locking receptacles 16.1, 16.2 the shoulders 15.1, 15.2 record positively.
  • the shoulders 15.1, 15.2 have to be expressed by taking advantage of their flexibility from the locking receptacles 16.1, 16.2 to zuzuschwenken the lid 11.
  • the lid 11 pivots with the stopper 13 into the vessel opening 6, which is facilitated by the extended insertion area 7. Thereafter, the sealing bead 13.2 is introduced into the sealing area 8.
  • the key 21 reaches its radius 25 on the radius 27 of the locking projection 9.2, as in Fig. 10 shown.
  • the tab 20 is deflected laterally outwards. Due to the flexibility of the tab 20 and bevels 24, 28 of the key 21 and the locking projection 9.2 this requires a slightly increased effort.
  • the latching edge 23 has reached the latching edge 29 of the latching projection 9.2 (cf. Fig. 11 )
  • the tab 20 springs towards the vessel 2 and the inner edge of the button 21 engages under the latching projection 9.2 (FIG. Fig. 4 . 5 ).
  • the locking takes place and the lid 11 secured to the vessel 2.
  • the user presses from below against the button 21 so that it is deflected laterally, as in the Figures 11 and 12 shown.
  • the lid 11 is moved out with the stopper 13 from the vessel opening 6 and opened.
  • the lid 11 is securely locked by the shoulders 15.1, 15.2 are engaged in the locking receptacles 16.1, 16.2 ( Fig. 8 . 9 ).
  • the lidded vessel 1.2 of Fig. 13 differs from the previously described 1.1 in that the flange 9.1 below not by crenellated projections 10.1, but is stabilized by a single, partially encircling bead-like projection 10.2, which is interrupted only in the region of the latching projection 9.2.
  • the locking according to Fig. 14 differs from the previously described Deckelverrastung characterized in that the locking projection 9.2 has a bevel 30 at the bottom.
  • the chamfer 30 is inclined to the vessel 2 upwards.
  • a support area 31 on the top of the key 2.1. is associated with a portion 31.1 at a distance from the locking edge 23 of the deepest portion 32 of the locking projection 9.2 or is applied to this.
  • Fig. 14 shown.
  • the partial area 31. 1 is arranged further outward than the connection of the tabs 20. 1, 20. 2 to the lid base 12.
  • the partial area 31.1 with respect to the vessel 2 is arranged further outward than the center of the connection of the tabs 20.1, 20.2 to the lid base 12.
  • Fig. 14 this is shown in a situation where the pressure inside the vessel is equal to the ambient pressure.
  • Fig. 15 shows the lidded vessel 1.3 in a situation in which the internal pressure in the vessel 2 exceeds the ambient pressure. Due to the increased internal pressure or a force exerted on the lid bottom 12 from the outside, the lid 11 is pushed upwards. Since the portion 31.1 is located further outward than the connection of the tabs 20.1, 20.2, a bending moment is exerted on the key 21 so that it bears against the bevel 30 flatly with its bearing area 31. As a result, the button 31 is prevented from slipping off the locking projection 9.2 and the lid 11 additionally secured to the vessel 2. In this embodiment, therefore, an increased internal vessel pressure or a vertically acting force supports the Verrasturig the lid 11 with the vessel. 2
  • the lidded vessel 1.4 of FIGS. 16 and 17 differs from the lidded vessel 1.1 according to Fig. 1-12 in that it has no lid projection 18. This design has the advantage of less expensive production, as material and tool costs are saved.
  • the lidded vessel 1.5 of Fig. 17 and 18 has in contrast to the lidded vessel 1.1 of Fig. 1 to 12 only a single tab strip 20.3, which is connected at the bottom with a plate-shaped button 21.
  • the key 21 is wider than the tab strip 20.3 and protrudes from both sides of the tab strip 20.3.
  • the inner upper edges of the button 21 form locking edges 23.2, 23.3. Including the button 21 on the inside chamfers 24.2, 24.3 and below radii 25.2, 25.3.
  • the locking edges 22.2, 22.3 are locked on the underside of the locking projection 9.3.
  • the locking projection 9.3 has a tab associated with the vertical recess 9.4, in which the tab strip 20.3 engages when the locking edges 23.2, 23.3 engage under the locking projection 9.3.
  • the lidded vessel 1.6 according to FIGS. 20 and 21 has three evenly distributed over the circumference Deckelverrastened 9.2, 19. These are each according to the Deckelverrastung 9.2, 19 of the lidded vessel 1.1 of Fig. 1 to 12 educated. Between the lid 11 and vessel 2, a hinge is present.
  • the lid 11 can be locked evenly with the vessel 2.
  • the security against unintentional opening of the vessel and increased density can be achieved. This is especially true for lidded vessels with a relatively large diameter (eg with a volume of 10 milliliters and more).
  • the lid 11 is closed by pressing in Veitikalcardi down on the vessel 2 until all locking has taken place.
  • FIGS. 22 and 23 shows a lid vessel 1.7 with smaller keys 21.2 than in the above-described embodiment.
  • the keys 21.2 can optionally be operated with the thumb. It is also possible to detach the lid 11 from the vessel 2 by pressing upwards in this lidded vessel 1.7.
