Description
- The present invention relates to a biological specimen collection container and in particular to a biological specimen collection container having an integral closure indicator to indicate when the container is properly sealed.
- Biological specimen containers serve to assure the integrity of the biological specimen being collected for testing as well as to protect the health care professional or handler from the possible pathogens in the container. The safe handling of biological specimens has become increasingly critical in view of the increase in both the number and severity of potential hazards associated with the handling of such specimens. The onset of acquired immunodeficiency syndrome arising from infection by the highly contagious HIV virus has resulted in increased awareness of the need for safe handling of biological specimens. This factor, along with such factors as potential infection from hepatitis virus and the increased awareness of the carcinogenic properties of substances in common medical use has created a demand for biological specimen containers that are of reasonable cost and readily sealed.
- There are at present many plastic biological specimen containers in use, particularly those manufactured of polypropylene. Polypropylene has many of the required characteristics such as high resistance to leakage, chemical or biological infiltration, moderate cost, resilient yet substantially inert, stable at temperatures of normal use and relatively safely incinerated. However, polypropylene does have a tendency, when it is elastically deformed at pressure points such as the seal to gradually drawback from the pressure point thereby reducing the contact seal, resulting in increased susceptibility to leakage. In order to provide for this proper seal it is necessary that the cap or lid of the container be securely and completely screwed down. If this is not done, then the cap or lid may release and allow leakage of the contents of the container.
- There have in the past been some proposals for ways to indicate that the lid is completely sealed. One example of such a system is shown in United States patent number which describes a paper label placed on the lid and container for indicating when the container is properly sealed. However this system has a drawback in that should the label be removed from the lid or container the indication of proper sealing is no longer present
- There thus remains a need for a simple way of indicating that a biological specimen container has been properly sealed.
- The present invention provides for a biological specimen collecting container for holding a biological specimen in a long-term sustained and sealed environment. The biological specimen collecting container comprises a container for holding the biological specimen and a sealing closure. The container is of circular section and has a generally vertical side wall, the side wall at the top being provided with a first thread on an exterior surface thereof. The sealing closure has a peripheral groove to receive the container rim, an outer wall of the closure being provided with a second thread complementary to the first thread on the container for engagement therewith. The exterior of the outer wall of the sealing closure is provided with an integral indicator. The exterior wall of the container below the first thread is provided with an integral indicator in a position such that when the indicator of the closure lines up with the indicator on the container, the cap is secure and the container is closed and sealed.
- In an aspect of the invention, the integral sealing indicator is selected from a solid arrow shape, a triangle, square, rectangle and a plurality of vertically extending raised indicator bars or other shape which serves as an indicator on the vial portion of the container. The indicator on the cap may be a bar, an arrow or other shape to indicate the position of the cap relative to the container.
- In another aspect of the invention the integral indicator on the exterior wall of the container is a plurality of vertically extending raised indicator bars spaced along the outer wall, the bars increasing in length in the direction of closure of the cap.
- In another aspect of the invention the cap is provided with two integral indicator bars 180° apart on the exterior of the cap
- A preferred embodiment of the present invention is illustrated in the attached drawings in which:
-
FIG. 1 is a perspective view of a biological collection container in accordance with the present invention; -
FIG. 2 is a side view of the container ofFIG. 1 in the process of being closed; -
FIG. 3 is a side view of the container ofFIG. 1 in a closed configuration; -
FIG. 4 is a a perspective view of a second embodiment of a biological collection container in accordance with the present invention; and -
FIG. 5 is a side view of the container ofFIG. 4 in a closed configuration. - A preferred embodiment of the biological specimen collection container of the present invention is illustrated in the attached figures. A
container 10 is provided for holding a biological sample, thecontainer 10 being closed and sealed by asealing closure cap 12 as illustrated in the drawings. Thecontainer 10 andclosure cap 12 are engaged and held in engaged relationship by the use of complementary threads comprising a first thread 14 provided on the exterior of thecontainer 10 and a second thread 16 provided on the interior of the outer wall of thecap 12. - The
container 10 is circular in section having avertical side wall 18, abottom 20 and an open mouth 22 defined by a rim 24. Theside wall 18 below the rim is provided with a first thread 14 and below the thread 14 is provided anintegral sealing indicator 26, the function of which will be explained further below. In a preferred embodiment illustrated in the figures, theintegral sealing indicator 26 is provided as a plurality of individual vertically oriented raised lines on the exterior wall which increase in length in the direction of closure of theclosure cap 12. - Closure
cap 12 has aperipheral groove 28 to receive the container rim 24, thegroove 28 being defined by anouter wall 30,inner wall 32 and atop 34. The interior of theouter wall 30 is provided with asecond thread 34, complementary to the first thread 14 on the exterior of thecontainer 10. Theclosure cap 12 also has acrown portion 36 and aconnection portion 38 extending between thecrown portion 36 and theinner wall 32 of thegroove 28. The exterior of theouter wall 30 is provided with anintegral sealing indicator 40, the function of which will also be explained below. In the preferred embodiment illustrated in the figures,closure cap 12 is provided with twointegral sealing indicators 40 located 180° apart on the exterior of theouter wall 30. - When one wishes to close and seal the biological specimen container of the present invention, the
closure cap 12 is placed on the top of thecontainer 10 and turned in a clockwise direction to allow thecomplementary threads 14 and 34 to engage one another and thereby seal the container. The indication of cap closure is evident by the position of theindicator 40 on theclosure cap 12 relative to theindicator 26 on thecontainer 10. When theindicator 40 of theclosure cap 12 is positioned over any portion of theindicator 26 of thecontainer 10, theclosure cap 12 is secure and thecontainer 10 is closed. By providing theindicator 26 on thecontainer 10 as a plurality of individual bars increasing in length the positive engagement of the cap to the container of at least 95 kPa may be indicated. When theindicator 40 on the closure cap is 12 turned completely to the left of theindicator 26 on thecontainer 10, the sealing is 95 kPa compliant. - Several indicator positions, such a one to four or more, however for clarity one or two position points are preferred. As a product label may obscure on of the indicators a minimum of two indicators is preferred.
- The indicator profiles are machined into the steel molds thus the locations of the indicator profiles on the plastic vials and caps are located precisely.
- The
integral indicators container 10 andclosure cap 12 respectively. As the closure indicators are integral to the cap or container, there is no risk of the indicators becoming dissociated from the container and thus as they are always associated with the container, the user of the container always knows if the container is properly sealed. In addition, as the closure indicators are formed during the molding operation, the required position of the indicators is easily determined. One does not have to first securely seal the container and then attach an external closure indicator as in the prior art. This separate step is susceptible to error if the container has not been properly closed prior to attachment of the external closure indicator. - Although various preferred embodiments of the present invention have been described herein in detail, it would be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention of the scope of the appended claims.
