Definitions

  • PETRI-DISH/CULTURE PLATE AND A STACK OF PETRI-DISHES/CULTURE PLATES
  • This application concerns a petri-dish/culture plate and a stack of petri-dishes/culture plates.
  • the present application particularly concerns the field of testing in pharmaceutical and food processing and more particularly environmental monitoring of clean or ultra clean processing areas. It is also applicable to other processing situations where cleanness of a processing area or environment is to be determined and monitored, for example in the field of semiconductor, electronics or aircraft manufacturing.
  • petri- dish In the widest application the invention is applicable to all situations where petri- dishes/culture plates are employed.
  • the terms "petri- dish”, “culture plate”, “media plate”, “settle plate”, “nutrition plate” and “plate” are thus interchangeably used and generally refer to a device in the form of a receptacle or container that defines an internal space for accommodating and holding a culture medium, for example a nutrient agar-based test media or other suitable test media depending on the need, and has a lid or cover that seals the space and can be selectively removed to gain access to the space and preferably re-attached to seal the space.
  • the petri-dish/culture plate as more specifically described below is one of the most common examples of such device.
  • the collection media for example in the form of the media plates or settle plates, have to be repeatedly transferred into the production area and removed therefrom for further handling and evaluation.
  • This is commonly done in a manual process where one or more plates or petri-dishes are manually conveyed through a sterile transfer port into and from the interior of the production area.
  • the manual handling of the petri-dishes involves a high risk of contamination when handling the media plate after a lid, cover or seal has been opened, and a non-secure transfer of the media plates during the introduction, installation and removal, in particularwhen a plurality of them are handled in a batch.
  • the common petri-dishes are not particularly suitable for automated handling individually or in batches as they typically consist of a media plate holding the nutrient media and a lid or cover releasably covering the plate. It is difficult for automated handling equipment to securely grip, hold and transfer the smooth cylindrical surfaces of the media plate and/or lid/cover, and there is a high risk that lids are inadvertently opened, displaced or removed from their media plates during handling including the sampling, incubation and evaluation procedure, thereby compromising the detection result.
  • Petri-dishes/culture plates are known and generally comprise two members, i.e. a tray or receptacle 2 and a mating lid 3.
  • the tray or receptacle 2 and the lid 3 both have a round and shallow cylindrical shape.
  • the tray 2 includes a generally planar bottom wall 20 which is surrounded by an outer peripheral wall or skirt 21 which extends below the plane in which the bottom wall 20 is contained in order to form a lower wall portion 211.
  • the bottom wall 20 also includes another peripheral wall 22 which is concentric with the lower peripheral wall portion 211, but has a smaller diameter, so that it can be termed an "inner wall”.
  • the bottom wall 20 delimits with the inner wall 22 the space in which the culture medium is deposited.
  • the lid 3 has a top wall 30 and an in- or downwardly protruding peripheral wall 31.
  • the latter is dimensioned so as to be able to be positioned outside and around the inner wall 22 so as to seal the space holding the culture medium in a releasable manner.
  • the outer peripheral wall or skirt 21 may extend above the plane in which the bottom wall 20 is contained in order to form an upper peripheral wall portion 210 radially outside and concentric to the peripheral wall 22 as shown in figure 13 but that is optional for the purposes of the present invention and mainly serves to improve the sealing state between the lid 3 and the tray 2.
  • the tray 2 forms, below the bottom wall 20, an open housing L which is surrounded by the lower wall portion 211 and which has a diameter D which is dimensioned such as the lid 3 of an adjacent petri-dish/culture plate in a stack may be inserted into the annular space defined by this open housing L.
  • This situation is shown in Figure 13 in that the lid of the adjacent petri-dish/culture plate is illustrated in dashed lines within the open housing L of the upper petri-dish/culture plate.
  • the petri-dishes have a free lid and the petri-dishes are handled or stored in small piles or stacks where a number of the petri-dishes are freely placed one above the other. While this design allows quick separation of petri-dishes and opening of their respective lids, there is high risk of having the stack of dishes/plates fall during transportation, because they are not secured together. Further, it is difficult to separate a sub-section of the stack of dishes/plates without the risk to open accidentally the lid of one of the plates or to have the tray falling unless secured by a finger. If a stack of dishes/plates is to be transported, they must be tightly wrapped to avoid that the lids open accidentally during shipment, which lid-opening may lead to dehydration of the media.
  • US 2013/0095009 Al discloses another approach where a releasable locking connection is provided between the lid of one petri-dish/culture plate and the tray or receptacle of an adjacent petri-dish/culture plate in a stack.
  • the lid has, on its peripheral wall, protrusions or nipples which extend radially outward from the peripheral wall.
  • the receptacle includes the same number of additional radial protrusions which are formed on the lower portion of the wall and are turned towards the inside of the dish.
  • the transverse extension of these protrusions is provided so that, if the receptacle of one dish/p late and a lid of an adjacent dish/plate are superposed, the protrusions interfere when they are brought closer to each other and then pressure is applied on the upper dish to deform a bottom wall of the lid by which, in combination with a rotary movement of the dish relative to the other, it is possible to engage the protrusions into each other.
  • a certain disadvantage of this solution is that sub-groups of petri-dishes/culture plates are complex to be formed from a stack of plates and inadvertent opening of petri-dishes during the attempt to separate dishes from the stack is still a risk. Further, the design requires very specific mating lid and receptacles (trays) and is not easily applicable to the majority of basis petri-dish/plate designs.
  • the present application aims at providing a petri-dish/culture plate which allows forming a stack of petri-dishes that can be held together without risk to be accidentally disassembled but which allows forming of sub-groups or sub-stacks in a simple manner without the risk of accidental opening of dishes in the process.
  • the invention also aims at providing a stack of petri-dishes/culture plates, for example for use in environmental testing. Summary

  • the present petri-dish/culture plate 80 has, as basically described in the introduction in connection with Figure 13, a tray or receptacle 81 configured to receive, in an internal space, the culture medium M (see Figures 1 and 3).
  • a lid 82 is provided and configured to cover the tray 81 in that it is inserted about an inner wall surrounding the space in which the culture medium M is deposited.
  • the space is further delimited, in addition to the inner wall, by a bottom wall of the tray which can be either flat or partly recessed or grooved.
  • the lid 82 is a regular cylindrical lid with a substantially flat top wall, a surrounding raised upper rim at the outer periphery of the top wall, and a surrounding peripheral wall protruding downward and slightly outward in the radial direction from the upper rim of the top wall so as to be able to tightly engage and potentially snap-fit with the outer peripheral side of the inner wall of the tray.
  • the mating wall surfaces of the peripheral wall of the lid and the outer side of the inner wall of the tray may be inclined as shown to achieve a wedge-locking effect (see Figure 7).
  • the design of the lid is not particularly important as long as it fits into a space defined in the lower part of the tray as described further below. This is one of the advantages of the present invention as it allows accommodation of various common lid-designs without the need to substantially adapt and modify these designs.
  • the tray 81 is provided with a locking mechanism 83 that is configured to releasably connect adjacent dishes 80 to each other in an aligned stacked orientation, i.e. the locking mechanisms 83 are designed to create a tray-to-tray locking situation.
  • the locking mechanism 83 is formed in the trays so as to provide a releasable connection by engagement of one tray with a tray of an adjacent dish in the stack.
  • the locking mechanism 83 with its structures or members is integrally formed with the tray 81 in that it is provided in a peripheral skirt member 84 formed by the wall portion of the tray protruding downward from the plane of the bottom wall of the tray.
  • the skirt member 84 or lower portion of the wall at least partially surrounds the circumference of the tray 81, but preferably forms a skirt extending about the entire circumference.
  • the skirt or lower portion of the wall defines and surrounds a space that is open to the bottom and has a diameter dimension such that the lid of an adjacent lower dish in the stack may be inserted into the annular space (see for example Figures 4 and 5 and 7).
  • the skirt member 84 is accordingly formed so as to straddle an outer perimeter of the lid 82 of the adjacent dish 80 in the aligned stacked orientation.
  • the locking mechanism may comprise a mechanical, form-locking and/or frictionally engageable locking structure in various designs. While a single such locking structure on each tray could be sufficient to connect and releasably lock adjacent trays to each other to form the aligned stack, the locking mechanism may comprise a plurality (i.e. 2 or 3 or even a larger number depending on the size) of such mechanical, form-locking and/or frictionally engageable locking structures distributed about the circumference of the dish 80 (see embodiment of Figure 10).
  • One of the locking structures preferably each of them, includes locking portions configured to releasably connect to each other by friction or adhesion and/or with the form-locking engagement.
  • the locking structure includes mating male and female locking elements.
  • the female element includes a slot 88 formed in an upper section of the skirt 84 at a stepped transition section from the upper inner peripheral wall surrounding the space for the culture medium and the lower peripheral wall of the skirt surrounding the annular space for accommodating the lid of the adjacent dish.
  • the slot 88 extends from an inlet opening 88a over a certain length in the circumferential direction as shown in particular in Figure 6.
  • the inlet opening 88a of the slot 88 opens to an expanded inlet zone 88b that is open to the outer periphery of the tray between inner and outer spaced-apart sections of the peripheral wall of the skirt as shown in particular in Figure 5.
  • the outer spaced-apart section of the peripheral wall of the skirt in the engagement zone of the locking mechanism can be formed by reducing the wall thickness of a portion of the wall of the skirt adjacent the slot on the radially inner side or by displacing that portion outward in the radial direction.
  • the male locking element comprises a ridge 89 or expansion formed at least partially around the circumference of the lower end of the skirt or lower portion of the wall of the tray and protruding to the radial outside (it may additionally or alternatively protrude to the radial inside instead), as shown in particular in Figure 7.
  • the ridge 89 or expansion may be formed as a residue after partially removing or at least narrowing, over a certain distance, the peripheral edge or ridge on the lower end of the peripheral wall or skirt adjacent to the expanded inlet zone 88b to form an insertion section 89b of the ridge.
  • the insertion section 89b of the ridge allows that the lower end of the skirt can be axially inserted into the slot 88 from the top without impediment in a defined relative rotational position between two adjacent trays in a stacked orientation.
  • the circumferential length and radial width of the insertion section 89b is shorter than that of the slot 88 with the inlet zone 88b and it defines the extend of relative rotation needed to engage the ridge 89 with the slot 88, thereby preventing axial separation of the two.
  • the tray 81 of one dish 80 is thus provisionally placed above the tray 81 of another adjacent dish below as described before the male ridge 89 of the upper tray 81 is be engaged by rotation into the female slot 88 of the lower tray 81 via the inlet zone 88b and inlet opening 88a as shown in particular in Figure 5, i.e. the connection by engagement is effected upon a relative rotation of the aligned stacked of adjacent trays 81.
  • the ridge 89, just as the slot 88, does not extended about the entire circumference, but is limited to a length that corresponds to the desired angle of relative rotation between an unlocked state and a locked state.
  • the slot 88 and the ridge 89 are adjacent to each other but spaced apart from each other in a circumferential direction of the tray and in the stacking direction.
  • both locking portions of the locking structure are formed adjacent to each other on the same element they can be termed a "hermaphroditic" locking structure.
  • the engaged or locked end state (and thus the end position of the relative rotation of adjacent trays) is defined by a first stopper 85 of the locking mechanism 83 which is formed by a forward or leading step 89a of the insertion section 89b of the ridge in the circumferential direction as shown in Figure 5 and a leading end 88c in the circumferential direction of the slot 88. It may, however, be formed by a separate protrusion, formed at the appropriate position on the ridge or skirt.
  • the locking mechanism 83 may further comprise a second stopper 86 defining a disengaged end state of the locking structure as shown in Figures 1 or 4 and it may be formed by upper and lower external corners 86a, 86b (the top external corner 86b of the one tray getting in contact with the bottom external corner 86b of the adjacent tray) which are displaced from each other in the circumferential direction by the angle corresponding to that of the relative rotation required to effect the engagement of the locking mechanism.
  • the upper and lower external corners 86a, 86b of all the trays in a stack are aligned, within the stack, along an oblique line when they are all in the open position.
  • the tray 81 may comprise an additional visual and/or tactile detectable marking 87 of the states as shown, for example, in Figures 4, 5 and 8 so as to directly indicate to a user whether or not and which part of the stack or sub-group of the stack is in the locked or unlocked state. This can be achieved, as shown in the embodiment, by lines or markings on the outer periphery wall of the skirt, which are positioned such that they are aligned in the respective engaged or disengaged end state.
  • the tray 81 may be formed such that, in particular with respect to the dimension from the lower end at the ridge 89 to the lower side of the bottom wall of the space for accommodating the culture medium, in the locked state, the lid 82 of an adjacent lower dish 80 in the stack is axially pressed against the upper ridge of the inner wall defining the space for the culture medium so as to immobilize it in its closed position as shown in Figure 7.
  • lids are not directly dimensioned to achieve that effect, additional spacers may be provided (not shown) to fill a gap or spacing between the upper side of the lid and the lower side of the bottom wall. Further projections may be provided at an appropriate location to achieve that pinching and axial pressing effect in the stacked and connected orientation. Accordingly, the lid is freely removable when the dishes are dissociated from each other, and the lid is fully encapsulated and held or pinched between the trays of adjacent dishes when the trays are locked in the closed position. More specifically, the lid is immobilized axially between the upper surface or upper ridge of the inner wall of the tray and the lower surface of the bottom wall of the adjacent tray as shown in Figure 7. Increasing the number of locking structures about the periphery may also reduce the needed rotation angle for locking the trays together.
  • a mechanical locking hard point may be provided that must be overcome before reaching the relative rotation of two trays in the engaged end state.
  • the locking engagement between adjacent dishes (or more correctly their trays) can be repeated with a larger number of dishes in order to create a larger pile or stack as shown in Figures 8 and 9.
  • the locking mechanism it is possible to lock all dishes in the stack together at the same time by relatively turning the extreme trays of the stack until all intermediate trays are brought into the engaged end state by engagement of the first stoppers (which will be visible in that the markings on the trays are all aligned).
  • the first stoppers which will be visible in that the markings on the trays are all aligned.
  • the second stoppers 86 By gripping and rotating only the extreme trays in opposite direction, all intermediate trays will be pulled into the disengaged end state by the engagement of the second stoppers 86 which again can be visually seen in that the corresponding markings on the trays are aligned.
  • sub-groups of the trays in a stack can be formed and selectively locked or unlocked (see for example Figure 9).
  • a larger stack can be easily split into subgroups or sub-stacks by unlocking consecutive trays at the desired splitting level.
  • the present application provides a cap 91 configured to releasably connect to the locking mechanism 83 of the petri-dish 80 to immobilize the lid 82.
  • This cap 91 is similar to the tray design in the way that it has the same locking structures of the locking mechanism, in particular the male ridge, but without the female slot 88 (that can be nevertheless present, but is not required for the function).
  • the cap 91 is shown in Figures 11 and 12.
  • the use of the cap allows secure transfer of individual petri-dishes or of a stack of petri- dishes without the risk that the lid (of the upper- or outermost dish in the stack) is accidentally removed. Consequently, the lid does not need to have its own locking feature in order to immobilize it on the tray, but can be locked within the locking system of the application. It provides the effect that a stack or sub-stack can be arranged upside down if required, for example during incubation.
  • the outer wall of the tray i.e. the skirt member 84, has a large accessible surface that can be additionally used in certain dedicated zones to place traceability features like printed labels, manual writing, colour coded text, bar code, data matrix or RFID chips or other pieces of information storage. Such zones are shown as a blank space, for example in Figures 1, 8, 9 and 12.
  • the present application also pertains to a stack of petri-dishes/culture plates comprising a plurality of petri-dishes/culture plates 80 as defined herein releasably connected to each other in an aligned stacked orientation by engagement of the tray- to-tray locking mechanisms 83 of the petri-dishes/culture plates 80 in the stack.
  • Such stack can be advantageously used in connection with for use in environmental air testing.
  • the stack of petri-dishes may include the specific cap 91 locked to the outermost tray of the stack top provide a completely locked arrangement of petri-dishes.
