Definitions
- the invention relates to a cap assembly for a biological culture container, preferably a container for the cultivation of microorganisms from blood samples,
- the cap assembly includes a cap with a central aperture.
- a rubber grommet is situated in the aperture.
- the grommet is symmetrical, is dimensioned to perform reliably under high vacuum or high pressure within the container. It may also be provided with a recess to facilitate penetration by a hypodermic needle or syringe.
- the first type uses a rubber or elastomeric stopper force fitted into the neck of a bottle.
- the second prior art closure uses a flat rubber or elastomeric diaphragm held in place on the topof a bottle by a screw cap having a central opening.
- Bottles with a stopper often explode-or blow the stopper and boil over when autoclaved as the culture medium boils. In either case the container is rejected for use.
- the diaphragm has a tendency to be pulled into the bottle when a partial vacuum forms when the. bottle cools.
- the problem is aggrevated by the unreliability of the prior art devices.
- the failures occur somewhat randomly. They occur during autoclaving, immediately after cooling,during storage in the plant, prior to use or at the time of use. A sealed bottle at room temperature will, at times, fail when the temperature drops, increasing the vacuum. Failure may also occur after the blood sample is inserted.
- the diaphragm has a tendency to depress when a hypodermic needle is penetrating the diaphragm to introduce a sample, thus adding to the problem.
- lt isstill another object of the invention .toprovide a depression for facilitating the entry of a needle into and through the'grommet
- FIG. 2 is a section of the closure
- FIG. 3 is a section of the closure.
- FIG. 1 there is shown a biological c'ontainer 10 with a cap assembly embodying the principles of the invention.
- the cap assembly includes a'cap 12 and a rubber, or other resilient material, grommet 13.
- the cap 12 is made from a plastic or a metal stamping. It is a screw-on cap having threads complementing the threads of the container 10.
- the cap 12 also includes a central aperture 14 in which the grommet 13 is positioned.
- the disc portion 17 is compressed between the cap and the top of the container forming a seal. Also, typically, the container is sealed at high temperature. The vacuum created at cooling tends to suck the grommet in. This tendency is depicted by the central depression 21 in the grommet. See FIG. 2.
- the disc portion 17 tends to stretch and move that portion forming theseal toward the center of the container. This is a very common occurrence with rubber seals subjected to tension in a direction tending
- the disc diameter be at least 1.2 times the diameter of the aperture. A circular apertureis illustrated. For other shapedapertures, the dimensional ratio of at least 1.2 is. measured across the aperture along a common axis, i.e., colinearly. For added reliability, the disc diameter should be 1.5 times the diameter of the aperture.
- the added security of the 1.5 diameter comes into play when the grommet is punctured by a needle. See FIG. 3.
- the needle imparts an added force in the same direction as the suction force.
- the grommet will be pushed into the container. I
- the recess 19 reduces the amountof rubber a needle needs to penetrate to enter the container. This reduces the time needed necessary to pierce the grommet, thus further reducing the vulnerability of the grommet.
- the invention is similar to that described in US. Pat. No. 3,499,568, though it is clear that the patented device is different in the following respect. It is, in fact, a stopper which fits intothe bottle.
- the patented clo sure is assembled when the cap istightened. The upper part is only slightly larger than the central opening and very thin, and not capable of resisting being sucked in, in the absence of the stopper.
- the metal protective cap appears to be an essential function part of the system and the discussion centers about the use of Agar culture medium, which is typically prepared aseptically.
- cap assembly just described provides a reliable-biological container and avoids some of the most serious problems associated with prior art concepts.
- a grommet made from a'self sealing elastomer with spaced upper and lower disc portions joined by a portion configured to fit into the aperture, the upper disc being dimensioned to be at least 1.2 times the colinear dimensions of the aperture, the grommet is secured to the cap with the upper and lower disc portions in contact with the exterior and interior flat surfaces of the cap, respectively.
- a container comprising a bottle, a cap assembly for said bottle and culture under a partial vacuum in said bottle, said improvement comprising a cap assembly comprising:
- a grommet made from a self sealing elastomer with spaced upper andlower disc portions joined by a portion configured to fit into the aperture, the upper disc being dimensioned to be at least 1.2 times the colinear dimensions of the aperture, the grommet is secured to the cap with the upper and lower disc portions in contact with the exterior and interior flat surfaces of the cap, respectively.
