Ink tack

Claim 2

A theft-deterrent tack for application to an article to be protected against theft, said tack comprising: A) a first housing having an open end and ceiling and wall structure bounding an interior space extending to the open end, the ceiling and wall structure being continuous, B) a second housing secured to the first housing and closing the interior space except for at least one opening extending therethrough into the interior space, said second housing having a flat undersurface facing said interior space and a plurality of vial-confining members extending upwardly from said surface into said interior space, C) at least one frangible vial disposed in said interior space located in preselected position by said vial-confining members, said vial having a cylindrical central portion and respective end portions contiguous with said central portion, said cylindrical central portion being in generally linewise contact along its length with said second housing flat undersurface of said second housing, said vial having an article staining substance contained therein, and D) vial-fracturing means comprising a flat surface and a pin member, said flat surface of said vial fracturing means disposed in said interior space between said vial and the ceiling of said first housing and supported for movement therein to come into direct compressive contact with said vial, said pin member having one end attached to said flat surface of said vial fracturing means and being of sufficient length to protrude through an opening in said second housing, said opposite end of said pin member being pointed to pass through an article to be protected, the disposition of said vial cylindrical central portion in linewise contact along its length with said flat undersurface of said second housing and said flat surface of said vial fracturing means giving rise to vial compressive fracture, to release said article staining substance upon movement of said vial-fracturing means into fracturing relation with said vial.

Claim 3

The invention claimed in claim 1 wherein said theft deterrent tack include engaging the pin member free end.

Claim 4

The invention claimed in claim 2 wherein said flat surface is of disc shape.

Claim 5

The invention claimed in claim 3 wherein said second housing defines a plurality of openings therethrough in addition to said at least one opening.

Claim 6

The invention claimed in claim 4 wherein a pair of said vials is included and wherein said at least one opening is located between said vials.

Claim 7

In combination: a) an article intended to be protected from theft; and b) a theft-deterrent tack comprising: 1) a first component including A) a first housing having an open end and ceiling and wall structure bounding an interior space extending to the open end, the ceiling and wall structure being continuous, B) a second housing secured to the first housing and closing the interior space except for at least one opening extending therethrough into the interior space, said second housing having a flat undersurface facing said interior space and a plurality of vial-confining members extending upwardly from said surface into said interior space, C) at least one frangible vial disposed in said interior space located in preselected position by said vial-confining members, said vial having a cylindrical central portion and respective end portions contiguous with said central portion, said cylindrical central portion being in generally linewise contact along its length with said second housing flat undersurface, said vial having an article staining substance contained therewithin, and D) vial-fracturing means comprising a flat surface and a pin member, said flat surface of said vial fracturing means disposed in said interior space between said vial and the ceiling of said first housing and supported for movement therein to come into direct compressive contact with said vial, said pin member having one end attached to said flat surface of said vial fracturing means and being of sufficient length to protrude through an opening in said second housing, said opposite end of said pin member being pointed to pass through the article to be protected, and 2) a second component including releasable securement means for securing the first component to said article, the disposition of said vial cylindrical central portion in linewise contact along its length with said flat undersurface of said second housing and said flat surface of said vial fracturing means giving rise to vial compressive fracture to release said article staining substance upon unauthorized attempt to separate said first and second components.

Claim 8

In combination: a) an article intended to be protected from theft; and b) a theft-deterrent tack comprising: 1) a first component including A) a first housing having an open end and ceiling and wall structure bounding an interior space extending to the open end, the ceiling and wall structure being continuous, B) a second housing secured to the first housing and closing the interior space except for at least one opening extending therethrough into the interior space, said second housing having a flat undersurface facing said interior space and a plurality of vial-confining members extending upwardly from said surface into said interior space, C) at least one frangible vial disposed in said interior space located in preselected position by said vial-confining members, said vial having a cylindrical central portion and respective end portions contiguous with said central portion, said cylindrical central portion being in generally linewise contact along its length with said second housing flat undersurface, said vial having an article staining substance contained therewithin, and D) vial-fracturing means comprising a flat surface and a pin member, said flat surface of said vial fracturing means disposed in said interior space between said vial and the ceiling of said first housing and supported for movement therein to come into direct compressive contact with said vial, said pin member having one end attached to said flat surface of said vial fracturing means and being of sufficient length to protrude through an opening in said second housing, said opposite end of said pin member being pointed to pass through the article to be protected, and 2) a second component including releasable securement means for securing the first component to said article, the disposition of said vial cylindrical central portion in linewise contact along its length with said flat undersurface of said second housing and said flat surface of said vial fracturing means giving rise to vial compressive fracture to release said article staining substance upon unauthorized attempt to separate said first and second components.

Claim 9

The invention claimed in claim 6 wherein said second component is a locking member for releasably engaging the pin member free end.

Claim 10

The invention claimed in claim 7 wherein said flat surface is of disc shape.

Claim 11

The invention claimed in claim 8 wherein said second housing defines a plurality of openings therethrough in addition to said at least one opening.

Claim 12

The invention claimed in claim 9 wherein a pair of said vials is included and wherein said at least one opening is located between said vials.
