Abstract
Abstract A culture transporter having a pair of recesses formed in a body member to receive respectively, a culture medium and a culture swab with a closing strip secured to the body member to seal off the recesses one from the other for a completely sterile package with provision for removal and use of the culture swab in collecting a culture and return of the culture swab to the culture transporter with resealing thereof. A fracturable seal between said recesses permits flow of the culture medium to the tip of the swab to maintain the swab moist and the culture in a live condition until laboratory tests are performed on the culture. The body member and closing strip both have a generally planar configuration with the closing strip having an exposed flat face which may bear desired indicia. A tubular member of absorbent material is located at an end of the culture swab recess adjacent the culture medium recess to surround the culture swab tip whereby upon fracture of the seal between said recesses, the culture medium may flow to the tubular member which retains the culture medium and assists in retaining the culture swab tip in a moist condition.

Claim 2
Dependent Claim
113 words
A culture transporter comprising, a culture swab with absorbent material, a culture medium, a planar base formed with recess meaNs holding said culture swab and culture medium in spaced-apart relation to each other, with the culture medium released by pressure, a planar closing strip of flexible material removably adhesively secured to said planar base to close off said recess means and peelable from the planar base to permit removal and return of the culture swab, and a tubular member of absorbent material positioned in said recess means surrounding the absorbent material on a tip of the culture swab to retain the culture medium in association therewith after pressure release of the culture medium.
Claim 3
Dependent Claim
54 words
A culture transporter as defined in claim 1 wherein said recess means is separated by a contacting part of the planar base and planar closing strip to separate the culture medium from the culture swab and said contacting part being separable by manual pressure to permit flow of culture medium to the culture swab.
Claim 4
Dependent Claim
124 words
A culture transporter comprising a rigid formed base with a pair of spaced apart recesses separated by a narrow base section, a culture swab in one of said recesses, a culture medium in the other recess, a flexible closing strip adhesively secured to said formed base including said narrow base section to cover said recesses and seal the culture medium recess from the swab recess, whereby the closing strip can be peeled from the base a distance sufficient to permit removal and reinsertion of the swab without disturbing the culture medium, followed by resealing the closing strip to the base and breaking of the adhesion of the closing strip to the narrow base section to permit the culture medium to reach the reinserted swab.
Claim 5
Dependent Claim
124 words
A culture transporter comprising a rigid formed base with a pair of spaced apart recesses separated by a narrow base section, a culture swab in one of said recesses, a culture medium in the other recess, a flexible closing strip adhesively secured to said formed base including said narrow base section to cover said recesses and seal the culture medium recess from the swab recess, whereby the closing strip can be peeled from the base a distance sufficient to permit removal and reinsertion of the swab without disturbing the culture medium, followed by resealing the closing strip to the base and breaking of the adhesion of the closing strip to the narrow base section to permit the culture medium to reach the reinserted swab.
Claim 6
Dependent Claim
35 words
A culture transporter as defined in claim 3 wherein said base is generally planar except for said recesses and said closing strip is also planar to provide a flat exposed surface to carry desired indicia.
Claim 7
Dependent Claim
53 words
A culture transporter as defined in claim 3 wherein said recess holding the culture swab is approximately semi-circular in cross section and only slightly larger than the diameter of the culture swab whereby entry of ambient air into said last-mentioned recess during removal and reinsertion of the culture swab relative thereto is minimized.
Claim 8
Dependent Claim
55 words
A culture transporter as defined in claim 3 wherein a tube of absorbent material is positioned in the recess for the culture swab adjacent said narrow base section to provide a dam for culture medium when said adhesion is broken and to surround the tip of the culture swab and retain it in moist condition.
Claim 9
Dependent Claim
33 words
A culture transporter as defined in claim 6 wherein the culture medium, prior to use, is retained in its recess solely by sealing contact between said formed base and said flexible closing strip.
Claim 10
Dependent Claim
119 words
A culture transporter comprising a base of relatively rigid material formed with a first recess and a second recess, a culture medium in the first recess, a culture swab in the second recess, said recesses being separated by a narrow base section, a closing strip of flexible material attached to said base and the narrow base section to seal off said recesses, said transporter including provision for removal of a culture swab from the second recess and return of the culture swab thereto after use without disrupting the attachment of the flexible material to the narrow base section, and said attachment being rupturable by manual pressure to permit flow of culture medium to the tip of the culture swab.
Claim 11
Dependent Claim
119 words
A culture transporter comprising a base of relatively rigid material formed with a first recess and a second recess, a culture medium in the first recess, a culture swab in the second recess, said recesses being separated by a narrow base section, a closing strip of flexible material attached to said base and the narrow base section to seal off said recesses, said transporter including provision for removal of a culture swab from the second recess and return of the culture swab thereto after use without disrupting the attachment of the flexible material to the narrow base section, and said attachment being rupturable by manual pressure to permit flow of culture medium to the tip of the culture swab.
