Abstract

A sample strip is divided into a plurality of individual pieces arranged seriatim and connected in end-to-end fashion. The individual pieces are separated from each other as the strip is incrementally fed through a dispensing tip of a cartridge which controls the dispensing operation to insure that the samples are dispensed one at a time in a hygienic manner. The cartridge can be mounted in a display unit along with a plurality of similar cartridges.

Claims

1. A strip in combination with a dispenser, the dispenser including a dispensing tip and a pair of force-exerting members adapted to exert a force against said strip as said strip passes through the dispensing tip, said strip comprising a pair of side edges and dividing lines which extend across said strip from one of said side edges to the other of said side edges and which are spaced apart along the length of said strip such that said strip is divided into a plurality of individual pieces arranged seriatim and connected in end-to-end fashion, each of said pieces containing a sample and including a nose section which has a size and shape selected such that said nose section is spaced from both of said side edges of said strip, a midsection which extends rearwardly from said nose section to a nose section of a trailing piece and which extends across said strip from one of said side edges to the other of said side edges,.and a tail section which includes a pair of legs extending rearwardly from said midsection to a midsection of the trailing piece, one of said legs being arranged adjacent to one of said side edges of said strip and the other of said legs being arranged adjacent to the other of said side edges of said strip such that said legs straddle the nose section of the trailing piece so as to present contact surfaces for the force-exerting members of the dispenser as the strip passes through the dispensing tip, whereby the force-exerting members do not exert any substantial force on the trailing piece until the midsection of the trailing piece reaches the force-exerting members at which time the leading piece can be separated from the trailing piece along one of said dividing lines by pulling on the leading piece as the trailing piece is maintained substantially stationary due to the force exerted on the midsection thereof by the force-exerting members, and both of said legs having a length selected such that upon the separation of the leading piece from the trailing piece the nose section of the trailing piece, which now becomes a leading piece, projects outwardly from the dispensing tip a distance sufficient to permit it to be gripped by a user.

2. A strip according to claim 1, wherein each of said sample is a cosmetic product sample.

3. A strip according to claim 1, wherein each of said pieces contains a transferable test sample, said test samples being applied to one surface of said strip.

4. A strip according to claim 3, wherein said strip is in the form of a roll.

5. A strip according to claim 4, wherein said strip includes a covering removably applied to said one surface of said strip, whereby said covering prevents contamination of said samples and prevents said samples from being rubbed off onto an opposite surface of said strip.

6. A strip according to claim 1, wherein said strip includes nicks which interrupt each of said dividing lines at preselected locations therealong to thereby connect each of said pieces to an adjoining piece, said dividing lines otherwise extending completely through said strip.

7. A dispenser for a strip which is divided into a plurality of individual pieces arranged seriatim and connected in end-to-end fashion, said dispenser comprising a dispensing tip, having a passageway through which the strip passes during a dispensing operation, first exerting means for constantly exerting a compressive force against one marginal edge only of the strip in a direction generally perpendicular to a longitudinal axis of the strip when the strip is flat, and second exerting means for constantly exerting a compressive force against an opposite marginal edge only of the strip in a direction generally perpendicular to the longitudinal axis of the strip when the strip is flat, said first and second exerting means cooperating as a result of the compressive forces exerted thereby to create drag on a trailing piece of the strip which trailing piece is supplied to said dispensing tip as a result of the withdrawal from said dispensing tip of a leading piece of the strip which leading piece is connected to the trailing piece, such drag being greater than the tensile force required to separate the leading piece from the trailing piece, whereby the leading piece can be separated from the trailing piece by pulling on the leading piece as the trailing piece is maintained in said dispensing tip due to the drag which inhibits movement of the trailing piece as the leading piece is separated therefrom, but not so great as to prevent the trailing piece from being moved through and out of said passageway of said dispensing tip.
