A quick tear open specimen bag for use such as by gloved medical personnel including first and second panels connected along side and bottom edges to define an interior accessible through an open top. A pair of sealable portions extend proximate the open top and are engageable to close the interior after depositing a specimen therein. A third panel secures in overlaying fashion to a selected one of the primary panels to define a second interior for receiving an indicia insert. Gripping lines are configured into each of the first and second panels, between the sealable portions and the interior, and upon being engaged create an even and smooth edged tear to reveal the primary and secondary interiors.

1. Field of the Invention
The present invention relates generally to plastic bag enclosures, such as for holding a medical specimen or the like. More particularly, the present invention teaches a multi-pocket bag device for respectively holding a medical specimen and associated medical literature. A pair of opposing resealable portions facilitate initial sealing of the specimen within the bag. A plurality of closely spaced and parallel extending grip lines extending between the sides of the bag facilitating quick “tear away” of an upper bag portion including the resealable beads, and such as for use by medical personnel wearing gloves and the like.
2. Description of the Prior Art
The prior art is well documented with examples of reclosable plastic bag devices, these each typically including male and female extending and interlocking profiles, as well as a sealed and moisture resistant interior. The use of such bags is prevalent in the known art and for a wide range of applications.
The Taheri, Safeguard Specimen Bag (U.S. Pat. No. 6,149,302) teaches a bag exhibiting tamper-evident features and including an adhesive flap foldable to cover the mouth of the bag to deter and indicate tampering with the contents and including access to a secondary compartment in which such as within which an insert is located. The indicia on the bag is visibly altered by attempts to release the adhered flap. A tear zone in the form of a reduced thickness section (see at 350 in FIGS. 12-14) is formed into the sides of the bag between opposite side edges and, upon being engaged, creates a ragged and open end for retrieval of an interiorly held specimen.
U.S. Pat. No. 5,186,543, issued to Cochran, teaches an easy open container exhibiting guide strips, in the form of protruding beads attached to the protruding surface of the ply material. The guide strips, according to one embodiment, are included with one or more tear strips on a member, which may be attached to a container (see FIG. 13 of the Cochran disclosure).
PCT/WO92/16422, to Levy, teaches a multi-pocket medical specimen bag, again including a single weakened tear line 40 for easy open. The bag is constructed of three overlaying sheets of clear plastic joined along three common edges to create two separate pockets open along a fourth edge of the assembled sheets. One of the sheets includes an adhesive flap foldable against the exposed fourth edges of the remaining sheets for sealing all of the pockets. The sealed end is torn off along a rear (perforated) tear line (shown at 40) to regain access to all pockets.
Sklar, U.S. Patent Application Publication No. 2003/0217943, teaches a dual chamber medical specimen bag with a single weakened/perforation line 136 extending across each of first and second plies (see FIG. 7). Reference is also made to the Bowman U.S. Pat. No. 5,135,313, Levy U.S. Pat. No. 5,102,234 and Laske U.S. Pat. No. 6,913,388 patents, and which are cumulative of those previously described.
The present invention teaches a multi-pocket bag device for respectively (and individually) holding a medical specimen and an associated (medical) literature insert. Resealable portions are defined, in inwardly opposing fashion, between first and second panels of the bag and may include male and female biasingly engaging portions, as well a modified configuration utilizing an adhesive or heat sealing flap or the like. Also, a mechanical zipper can be employed. Upon pre-inserting a desired object (such as in particular a medical and/or biohazard related specimen or even a larger sized item such as a garment article or the like in the instance of a larger sized specimen bag enclosure) facilitate initial sealing of the specimen within the bag.
A flap overlays a third panel and secures along opposite common side edges of the three panels. The flap may be manipulated to gain access to an outer pocket associated with the multi-pocket bag device, and such as within which is held a paper insert or other indicia.
A plurality of closely spaced and parallel extending grip lines are arranged in aligning fashion along the first and second panels sides. The grip lines facilitate quick “tear away” of an upper bag portion including the resealable beads, and is used such as by medical personnel wearing gloves.
The configuration of the tear lines is such that they define, in cross section, interiorly projecting barbs and, to a lesser extent, opposite and outwardly projecting points, these further providing a degree of tactile “feel” during handling and tearing open of the bag by a user. The plural tear line arrangement is further such that it exhibits a thickness at least as great as anywhere along either of the main panels, and therefore does not weaken the structural integrity of the panels. Upon the user ripping open the bag, a uniform and non-ragged edge results from tearing open, this being formed between a given succeeding pair of tear lines associated with each panel.
An interconnecting edge associated with the third flap overlay may also be positioned in parallel extending fashion between the grip lines and the resealable portions and, upon tearing open the bag, incises the interconnecting edge for fully opening the second panel containing the literature insert, concurrent with opening the primary specimen holding compartment. It is also contemplated that further modifications of the bag structure may either do away with the third panel, rendering a single enclosure, or may add a fourth opposite edge panel for creating first, second and third individual enclosures.
Additional features further contemplate notching common edges of the bag along a zone defined by the tear lines, and to further facilitate easy and even tear opening of the bag. The exterior facing surface of the first panel further may exhibit a desired indicia arrangement, including such as “BIOHAZARD” and Design warning, and including indicia applicable checklists, such as further to identify a given temperature zone (e.g. Frozen, Refrigerate, Room Temperature) in which to store the bag contents. It is further contemplated that such as a commercial identifying name may be imprinted upon the bag, such as in multiple fashion along its tear zone defined by the plurality of gripping and tear lines.

The bag device includes a first main panel 16 and a second main panel 18 which are interconnected together along opposite sides 20 and 22 and a bottom edge 24, so as to define a primary interior 25 accessible through an open top 26 (referring again to
Resealable portions 28 and 30 are defined, in inwardly opposing fashion, between the first 16 and second 18 panels of the bag 10, and typically a spaced distance from its top 26. The resealable portions typically include inwardly opposing male and female interengaging portions, as is known in the art. As further best shown in the enlarged view of
