Abstract
The invention provides a secure and adjustable culture dish rack for the purpose of holding a plurality of culture dishes. The rack includes a weighted base with a plurality of hairpin constraint rods on the circumference of the base, where the constraint rods individually support adjustable appendages that interlock at the centre of the rack to secure the culture dishes, and where the constraint rods may be removable. The weighted base prevents tipping of the rack, while in the event of an overturning, the interlocking adjustable appendages keep the culture dishes secure within the constraint rods. The removable constraint rods increase accessibility for dish loading.
Description
Adjustable Culture Dish Rack The present invention relates to a device for storing and handling laboratory objects, in particular, culture dishes. Furthermore, the invention relates to a storage device, an incubation device, a storage rack, as well as a laboratory device.
Background of the Invention Culture dishes are flat circular cup-like receptacles or containers with a spanning lid, featuring a depending skirt that loosely fits the container. Said dishes are widely used in biology and medicine.
Culture dishes are thereby used for the cultivation of cell cultures and microorganisms. Commonly, a flat gel-like layer of culture medium is placed into the bottom of the dish to supply the growing microorganisms with water and necessary nutrients. Notably, culture dishes are stackable, the use of a rack allows for higher stacking due to constraints around the culture dishes for dish storage or incubation.
Among specimens, a culture dish may be used for the incubation of pathogenic microorganisms.
During the incubation period of the microorganism in the culture dish, the growth of the culture may be inspected several times. This requires removal from the incubator and transporting to the working area for observation. During transport, current culture dish racks may tilt or fall, risking the opening of the culture dishes on the rack, as the lid of most culture dishes are a loose fit. Opening the dish exposes the user and environment to the contents of the culture dish, and the culture dish to environmental contaminants. There is currently a need for accommodating a plurality of culture dishes in a secure manner to prevent accidental exposure of the inside of the culture dish to the environment.
The current use of storage racks for culture dishes requires the loading and unloading of culture dishes in the working area. Commonly used culture dish racks are composed of a rigid fixed frame and the action of loading and unloading culture dishes is partially obstructed by the tall fixed constraint rods.
Description of Prior Art As seen in the prior art, the following patents have attempted to provide an alternative to securing a plurality of stacked culture dishes. However, none of them have accounted for providing the user with increased accessibility to the stacked dishes and securing the dishes in the occurrence of the overturning of the rack.

Description Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings. FIGs. 1, 2, 3, and 4 show a culture dish rack 1 of the invention, and FIG. 12 shows a state where a plurality of culture dishes 23 are stacked in the culture dish rack.
The adjustable culture dish rack 1 shown in the figures comprises: a weighted base plate 14 which is formed of stainless steel or the like into a disk-like shape; a plurality of singular hairpin constraint rods 2 integrally projected from the upper face of the base plate or coupled to the base plate by a T-slot cavity 18 in the base plate 14 and a constrain rod adapter 25 at the ends of a singular hairpin constraint rods; a transverse support crossbar 5 wherein the diameter of a constraint rod may pass and the crossbar may slide freely; a receptacle appendage 9 and a fastening appendage 8 that swings via hinge 7 that is attached to the transverse support crossbar 5.
The weighted base plate 14 is equally effective as a solid or unfilled structure so long as the centre of mass favours the lower third when the rack is loaded with culture dishes. The weighted base plate is equally effective as any rigid or elastic composition so long as it is heat resistant and capable of being decontaminated. The embodiment of the invention requires at least one pair of T-slot cavities 18 on the upper face of the weighted base plate to accompany the constraint rod adapter 25 of a hairpin constraint rod 2, providing increased accessibility for plate loading and unloading.
In the figures, three hairpin constraint rods 2, which is the suggested number, are shown. Although the number is not particularly restricted, the three constraint rods can sufficiently stack culture dishes 23. Less constraint rods reduce the security of the culture dishes. The hairpin constraint rods are located equidistant from the centre of the base with the wide face of the hairpin facing the centre to accommodate the appropriate diameter of the culture dish.
In the figures, only one of the hairpin constraint rods 2 is removable via a constraint rod adapter 25 inserted in the T-slot cavity 18 of the weighted base plate 14, while the other two constraint rods are fixed to the base plate by methods dependant on the material of the base plate and constraint rod, be it welding or resin. Although the number of removable constraint rods and T-slot cavities are not particularly restricted, aside from the minimum of one set.
A hairpin constraint rod 2 with constraint rod adapter 25 once inserted in to the T-slot cavity 18 of the weighted base plate 14, is then slid forward down the T-slot cavity to the resting position 22. A plug 15, consisting of a solid elastic material with matching dimensions to the insert position of the T-slot cavity, follows the insertion of the hairpin constraint rod and prevents the constraint rod adapter and constraint rod from sliding out of the T-slot cavity. A handle 16, consisting of a fabric or rigid material, is fixed equidistantly on the upper face of the plug.
Each hairpin constraint rod 2 has a transverse support crossbar 5 with two perforations to accompany both sides of the hairpin constraint rod which allows free sliding of the crossbar. An imbedded press button 4, flanks either side of the crossbar, containing a piston and biasing spring that, when at rest,
Description Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings. FIGs. 1, 2, 3, and 4 show a culture dish rack 1 of the invention, and FIG. 12 shows a state where a plurality of culture dishes 23 are stacked in the culture dish rack.
The adjustable culture dish rack 1 shown in the figures comprises: a weighted base plate 14 which is formed of stainless steel or the like into a disk-like shape; a plurality of singular hairpin constraint rods 2 integrally projected from the upper face of the base plate or coupled to the base plate by a T-slot cavity 18 in the base plate 14 and a constrain rod adapter 25 at the ends of a singular hairpin constraint rods; a transverse support crossbar 5 wherein the diameter of a constraint rod may pass and the crossbar may slide freely; a receptacle appendage 9 and a fastening appendage 8 that swings via hinge 7 that is attached to the transverse support crossbar 5.
The weighted base plate 14 is equally effective as a solid or unfilled structure so long as the centre of mass favours the lower third when the rack is loaded with culture dishes. The weighted base plate is equally effective as any rigid or elastic composition so long as it is heat resistant and capable of being decontaminated. The embodiment of the invention requires at least one pair of T-slot cavities 18 on the upper face of the weighted base plate to accompany the constraint rod adapter 25 of a hairpin constraint rod 2, providing increased accessibility for plate loading and unloading.
In the figures, three hairpin constraint rods 2, which is the suggested number, are shown. Although the number is not particularly restricted, the three constraint rods can sufficiently stack culture dishes 23. Less constraint rods reduce the security of the culture dishes. The hairpin constraint rods are located equidistant from the centre of the base with the wide face of the hairpin facing the centre to accommodate the appropriate diameter of the culture dish.
In the figures, only one of the hairpin constraint rods 2 is removable via a constraint rod adapter 25 inserted in the T-slot cavity 18 of the weighted base plate 14, while the other two constraint rods are fixed to the base plate by methods dependant on the material of the base plate and constraint rod, be it welding or resin. Although the number of removable constraint rods and T-slot cavities are not particularly restricted, aside from the minimum of one set.
A hairpin constraint rod 2 with constraint rod adapter 25 once inserted in to the T-slot cavity 18 of the weighted base plate 14, is then slid forward down the T-slot cavity to the resting position 22. A plug 15, consisting of a solid elastic material with matching dimensions to the insert position of the T-slot cavity, follows the insertion of the hairpin constraint rod and prevents the constraint rod adapter and constraint rod from sliding out of the T-slot cavity. A handle 16, consisting of a fabric or rigid material, is fixed equidistantly on the upper face of the plug.
Each hairpin constraint rod 2 has a transverse support crossbar 5 with two perforations to accompany both sides of the hairpin constraint rod which allows free sliding of the crossbar. An imbedded press button 4, flanks either side of the crossbar, containing a piston and biasing spring that, when at rest,
4 applies pressure to the constraint rod to prevent free longitudinal movement of the crossbar. Using two fingers to depress the press button, the piston and biasing spring release the pressure on the constraint rods and permit free movement of the crossbar. Each hairpin constraint rod contains fine groves 3 to enhance the grip of the press button mechanism 5.
Projecting towards the central axis of the baseplate 14 from the crossbar 5 is a fixed, right angle hinge 7 with a pin 6 passing through a fastening appendage 8 or receptacle appendage 9.
Preferably, the appendages will be of cuboid shape made of a polymeric material. Fastening appendages 8 as seen in FIGs 1,3 and 5 will have at least one small rounded projection 10 from its lengthwise faces perpendicular to the face of the base plate 14. The figures depict three small rounded projections on each lengthwise face of the fastening appendage, which is the preferred number. The receptacle appendage 9 is also preferentially of cuboid structure made of a polymeric material, though it is branched to connect with the fastening appendages 8. The ends of each cuboid branch are hollowed out by one third from above, leaving the bottom face 13, two outer faces 11 and creating an opening by removing the front face 17. In FIGs 2, 4 and 7, the receptacle appendage can accept the fastening appendage in an overlapping fashion. The receptacle appendage 9 will have at least one small rounded recess 12, matching the small rounded projections 10 of the fastening appendage 8, to loosely interlock the two appendages. In the embodiment of the invention, the interlocking projections and recesses of the appendages will not separate from the weight of culture dishes if the culture dish rack 1 were to become inverted, rather, they will only disengage under pressure applied by human hands.
The focus of the invention is for the use of stacking a plurality of culture dishes 23 with ease by removing one of the constraint rods 2 via pulling of the plug 15 and sliding out the constraint rod adapter 25 from the T-slot cavity 18. As well as ensuring the security and stability of the culture dishes via the adjustable crossbars 5 with interlocking appendages to prevent the culture dishes from opening.
Some uses for the invention include being placed in an incubator, in an anaerobic jar, or for the general storage of culture dishes.
While preferred embodiments of the invention are described in the present application, it should be noted that the invention is not restricted thereto and can also be carried out in a different manner within the scope of the following claims.
It is noted that the foregoing examples have been provided for the purpose of explanation and are in no way to be construed as limiting of the present invention.
