Urine specimen container
First Claim
1. A specimen container assembly comprising:
- a container having a mouth opening defined by a rim, a removable cap for closing said opening, a hole in said cap of substantially smaller diameter than said mouth opening, and a relatively thin impermeable liner sheet compressed between said removable cap and said rim for making a fluid tight seal with said rim, said liner being rupturable by moderate manual effort with the relatively blunt tip of a laboratory pipette having a tip width greater than the thickness of said liner to make a permanent non-self-resealing opening in the liner at the location of the hole, whereby a sample may be drawn from said container without removing said removable cap.

Abstract
A container for liquid medical specimens such as urine specimens includes a container with a wide mouth opening for facilitating deposition of a urine sample, a removable cap for closing the mouth opening and an impermeable sheet liner under the cap for making a fluid tight seal with the rim. The liner is rupturable with the blunt tip of a laboratory pipette inserted through a small hole in the cap for drawing a sample of a urine specimen without removing the cap of the container. The hole in the cap may remain open after collection of a urine specimen in the container, as leakage is prevented by the liner. Alternatively, a small secondary cap may close the hole in the main cap. An optional decanter may be inserted through the hole in the cap for piercing the liner to facilitate pouring of the contents without removing the cap. A method of using the novel container for conveying a liquid medical specimen from a specimen collection site to a geographically removed laboratory site is disclosed.

18. A system for conveying liquid specimens from a collection site to a laboratory site, comprising:
- a container having a neck with a rim, a mouth opening defined by said rim, a first cap engageable to said neck for closing said mouth opening, a hole in said first cap of substantially smaller diameter than said mouth opening and a rupturable non-self-resealing relatively thin sheet liner compressed between said cap and said rim for making a liquid tight seal against said rim; and
a decanter insert open between an upper end and a lower end much wider than the thickness of said sheet liner and having a midportion sized to make a close fit in said hole for supporting said upper end above said first cap with said lower end extending into said container, said lower end being adapted for piercing said liner through said hole, such that contents of the container may be dispensed by pouring through said insert without removing said first cap from said container. - View Dependent Claims (19, 20, 21)
