DETAILED DESCRIPTION OF THE INVENTION

While the present invention will be described with reference to a few specific embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications to the present invention can be made to the preferred embodiments by those skilled in the art without departing from the true spirit and scope of the invention as defined by the appended claims. It will be noted here that for a better understanding, like components are designated by like reference numerals throughout the various figures.

Turning now to FIGS. 1-9 a child resistant, zippered plastic bag assembly 20 is provided having an openable and recloseable mouth 21. The bag assembly includes a poly bag 22 with a first side panel 23 and an opposed second side panel 25 each having respective upper portions forming the mouth 21, opposing joined bottom sides 26, and first and second opposing, joined side edges 27, 28 that collectively define a storage volume between the panels. The bag assembly 20 further includes a zippered closure device 30 coupled to the respective upper portions of the first and second side panels 23, 25 for interlocking the mouth between a closed condition (FIGS. 1 and 5-8) and an opened condition (FIGS. 2 and 9). A slider device 31 is further included having a base member 32 operably mounted to, and cooperating, with the zipper closure device 30 for movement therealong between a first position (FIGS. 1 and 5-8), orienting the mouth in the closed condition, and a second position (FIG. 2), orienting the mouth in the opened condition. The slider device 31 includes a first wing 33 extending outwardly from the base member 32, adjacent the respective upper portion of the first side panel 23, and a second wing 35 also extending outwardly from the base member 32, adjacent the respective upper portion of the second side panel 25. In accordance with the present invention, a lock device 36 is operable between the first wing 33 and second wing 35, and is configured to cooperate with the first side panel and the second side panel in a locked state FIGS. 1, 6 and 7) to lock the slider device in the first position.

Accordingly, a typical plastic bag assembly with a zippered-style closure is provided that is capable of releasably locking the slider device 31 relative to the zippered closure, affixing the slider device to the poly bag (in the first position (FIGS. 1, 6 and 7), and retaining the zippered closure device in the closed condition. An effective child resistant plastic bag is created that can be unlocked and opened by an adult.

In particular, the lock device 36 includes a locking post 37 extending away from an interior surface of the first wing 33, toward the second wing 35 (FIGS. 5 and 10-13). The locking post 37 is configured to be manually positioned through a common aligned retaining aperture 38 through both the first and second side panels 23, 25, when the slider device 31 is oriented in the first position. Moreover, the locking post 37 can be moved into engagement with an aligned locking port 40 in the second wing 35, reorienting the first and second wings from an unlocked state (FIGS. 2-5 and 8-13) to a locked state (FIGS. 1, 6 and 7) to lock the slider device 31 in the first position, and thus the zipper closure device 30 in the closed condition (FIGS. 1 and 5-8).

Referring now to FIGS. 1 and 2, the bag assembly 20 preferably includes a conventional collapsible poly bag 22 having essentially the first side panel 23 and the opposed second side panel 25 disposed in an adjacent, side-by-side relationship that can be heat sealed peripherally all around, or at selected common edges thereof. The section at the mouth 21, of course, is not heat sealed together and contains the zippered closure device to releasably seal the contents stored within the storage volume or cavity of the bag assembly 20.

Similar to conventional sandwich-style poly bags, the zipper closure device 30 is employed so that the mouth 21 can be opened and closed manually in a reusable manner. More preferably, this zipper closure device 30 primarily consists of opposing, rectangular-shaped first and second support sheets 42, 43 each of which house interlocking first and second track members 45, 46, respectively. These first and second support sheets 42, 43 are melded, adhered and/or molded into the upper portions of the respective first and second side panels 23, 25, respectively, thus becoming single units therewith, proximate to the mouth 21. The first track member 45 and the second track member 46 are disposed opposite to, and aligned with, one another such that when the respective track members 45, 46 are fully engaged (FIGS. 1 and 5-8), access to the cavity through the mouth, in the closed position, is not permitted. In contrast, when the opposed track members 45, 46 are completely unengaged, (FIG. 2), access to the cavity via the mouth 21 in the opened position is permitted.

Rather than manually pulling apart, or pushing together, the opposed first and second track members 45, 46 in order to operate the zipper closure device 30, the slider device 31 (FIGS. 1-3) is provided that straddles, and slides longitudinally along, the top edges of the zipper closure device 30 between the first position (FIGS. 1 and 5-8), causing the track members 45, 46 to disengage from one another in the opened condition, and the second position (FIG. 2), causing the track members to engage with one another in the closed condition.

The slider device 31 is preferably composed of a polymer material, and includes a conventional internal divider wedge 47 (FIGS. 5, 12 and 13) configured to force the interengaged track members 45, 46 apart as the wedge is moved longitudinally therealong from the first position toward the second position. Conversely, on the other internal side of the slider device 31, a conventional closer device is provided that forces the opposed track members 45, 46 together and into inter-engagement with one another as the slider device is moved longitudinally along the track members 45, 46 from the opened condition toward the closed condition.

Referring now to FIGS. 10-13, the slider device 31 includes a generally rectangular shaped base member 32 having a first slider wall 48 and an opposite second slider wall 50, both of which extend downwardly from an upper portion thereof, in a straddling manner from the zippered closure device 30 top edges. The first slider wall 48 extends downwardly and adjacent to the first support sheet 42 and/or first side panel 23 as well, depending upon the particular fabrication between the poly bag and the zippered closure device 30. Similarly, the opposite second slider wall 50 also extends downwardly and adjacent to the second support sheet and/or the second side panel 25 of the bag.

In accordance with the present invention, the reusable child resistant bag assembly 20 includes the lock device 36 cooperating between the first and second wings 33, 35 to releasably lock the slider device 31 in the first position. As indicated above, a locked slider device will retain the zippered closure device 30 in the closed condition until selectively released. The lock device 36 is preferably incorporated into, and part of, the wings 33, 35 of the slider device 31. Further, the locking post 37 of the lock device cooperates with the poly bag 22 itself and/or the support sheets 42, 43 of the zipper closure device 30 (FIG. 5), as well as with the aligned locking port 40 to secure the slider device in the first position (FIGS. 1 and 5-8).

As best viewed in FIGS. 8 and 9, the locking post 37 of the lock device 36 can be manually removed from the aligned locking port 40, in the locked state (FIGS. 1, 6 and 7) to the unlocked state (FIGS. 2-5 and 8-13), by someone other than a young child. This disengages the locking post 37 from engagement through the retaining aperture of the poly bag 22 so that the slider device 31 can be moved toward the second position, enabling the closure device 30 to move the bag mouth to the opened condition.

Each of the opposed first and second wings 33, 35 extend distally (generally in the direction of motion as the slider device moves from the second position toward the first position) from a side of the respective first and second slider walls 48, 50 of the slider device 31. These wings 33, 35 are integrally formed with the slider device 31, but are generally thinner than that of the respective slider walls 48, 50 so as to be relatively flexible for movement between the locked and unlocked conditions.

As mentioned, to facilitate locking of the lock device 36, a locking post 37 extends laterally away from the interior surface of the first wing 33 toward the opposed interior surface of the second wing 35. This locking post 37 extends in a direction generally perpendicular to both the first and second wing 33, 35, and is of a longitudinal length sufficient to span through at least the poly bag 22, and engage the second wing 35, in the locked position.

The lock device 36 further includes a mushroom-shaped head portion 51 (FIGS. 12 and 13) at the distal end of the locking post 37 having a diameter and circumference slightly larger than that of the central portion locking post 37. This slight dimensional increase in the circumferential footprint of the head portion enables a conventional snap-fit or press-fit type engagement through the strategically aligned wing locking port 40 extending laterally through the second wing 35.

Similarly, when the slider device 31 is moved fully to one end of the track members 45, 46 (i.e., the first position), placing the track members in the fully interengaged condition (FIGS. 1 and 5-8), the retaining aperture 38 that extends laterally through the first side panel 23 and the second side panel 25 of the poly bag is strategically placed to enable passage of the locking post 37 therethrough (FIG. 5), enabling the locking post 37 to be moved to the locked condition.

To move the head portion 51 through the second wing locking port 40, into the locked condition, the exterior surfaces of the respective first and second wings 33, 35 are manually compressed together (e.g., FIG. 6), forcing the head portion 51 through the wing locking port 40. The slider device 31, hence, is retained in the first position, retaining the closure device in the closed condition (FIG. 7).

To increase the structural integrity around the wing locking port 40, an annular support ring (not shown) may be provided on the interior surface, the exterior surface, or both surfaces of the second wing 35. Radial slits (not shown) may also be incorporated to facilitate flexibility of the wing locking port 40 so that the head portion of the locking post 37 can be more easily positioned therethrough.

Alternatively, as best viewed in FIGS. 10 and 11, the locking port 40 may include one or more retaining tabs 55 that extend radially into the locking port 40. These one or more retaining tabs 55 are integral with the circumferential walls that define the port, and are elastically configured to facilitate retention of the head portion 51 of the locking post 37 therethrough, in the locked state. To remove the locking post therefrom, to the unlocked state, a sufficient amount of force (see FIG. 8, and as will be described in greater detail) is applied axially to the head portion to force the locking post 37 out of the locking port 40.

Accordingly, depending upon the footprint differential between circumference of the head portion 51 and the wing locking port 40, the material thereof, and the overall thickness of the wing, including the annular ring, if necessary, as well as other physical attributes (i.e., slits 53 or retaining tabs 55), the force necessary to position the head portion 51 of the lock device 36 through and out of engagement with the wing locking port 40 can be manipulated. For instance, using these variables, the lock device 36 can be designed so that at least a sufficient force (e.g., 2-10 lbf) is necessary to withdraw the head portion 51 of the lock device 35 through the wing locking port 48 to unlock the lock device 35, or to conform with the required safety standards such as ASTM D3475 (the Standard of Classification of Child Resistant packages), or Title 16 CFR 1700 (the requirements for child resistance stated in the Poison Prevention Packaging Act).

As best viewed in FIGS. 5-13, the first and second wings 33, 35 are sufficiently long, so as to provide respective, distal tabbed end portions 56, 57 that extend distally past the central location of locking post 37 and wing locking port 40, relative to the wings. These tabbed end portions 56, 57 enable the operator to grip and pull the engaged lock device 36 apart, releasing the head portion 51 from locked engagement with the wing locking port 40.

The respective tabbed end portion 57 of the second wings 35 is longer than that of the first wing 33 to promote gripping thereof for increased manipulation of the lock device to both move the locking post to the locked state, as well as remove the post from the locked state to the unlocked state. Although the flexible nature of the first and second wings themselves allow the locking post 37 to be engage into or be withdrawn from the retaining aperture 38, for example, by those six years and older, this off-set configuration of the tabbed end portions 56, 57 facilitates operation of the lock device, effectively allowing a stouter lock device to be incorporated.

More preferably, as best illustrated in FIGS. 6-8, the longitudinal length of the second wing 35 is significantly longer than that of the is first wing 33, and is further rconfigured such that when the slider device 31 is in the first position, the distal tabbed end portion 57 of the second wing 35 terminates proximate to the common edge 27 of the first and second side panels 23, 25. By configuring the second wing 35 adjacent to the sheet panels, and such that the second wing distal end terminates adjacent to the sheet panels common edge 27 (while the tabbed end portion 56 of the first wing 33 does not), when slider device is oriented in the first position, both the sheet panels 23, 25 and the second wing 35 can be employed to facilitate both engagement and release of the locking post 37 into and from the locking port 40. That is, as best illustrated in FIG. 8 for instance, a significantly larger area of the side of the first side panel 23 can be utilized to push against the second wing 35 (as compared to only gripping the second wing) to facilitate release mushroom-shaped head portion of the locking post 37 from the tabbed locking port 40. Accordingly, this off-set configuration, as well as the removal technique utilized, significantly simplifies the simultaneous release the locking post 37 from both the locking port 40 and the retaining aperture 38 of the bag assembly 20 while still maintaining sufficient integrity to be child proof.

In one specific embodiment, the first and second wings 33, 35 may be integrally connected to the respective first and second slider walls 48, 50 through respective neck portions 58, 60 (FIGS. 10, 11 and 14). These narrower neck portions 58, 60 enable more flexibility of the respective wings 33, 35 to move between the locked and unlocked positions.

Turning now to FIGS. 1 and 14, first and second wings 33, 35 can be angled slightly downward, positioning the locking post 37 below the base member 32. This is advantageous in that the wings are repositioned out of the general horizontal level of the slider base member 32, facilitating operational gripping of the wings.

To also increase the structural integrity around the retaining aperture 38, so as to retain and maintain the locking post 37 therein, the surrounding area around the retaining aperture, between the first and second side panels 23, 25 of the poly bag 22 and the respective first and second support sheets 42, 43 of the closure device 30 can be heat sealed together using conventional means, strengthening the bond. This may be performed when the ends of the track members 45, 46 are heat sealed together, forming unitary support ends of the adjacent first and second support sheets. Moreover, structural eyelet devices (not shown) may also be incorporated around the retaining aperture 38 to further bulk up this region.

Referring now to FIGS. 15 and 16, an alternative embodiment is provided where the lock device 36 includes a second locking post 61, disposed adjacent the first locking post 37, as well as a corresponding second locking port 62 on the second wing 35. The outermost, second locking post 61 is preferably outside and adjacent to the common edge 27 of the first and second side panels 23, 25.

Hence, when the second locking post 61 of the lock device 36 is in the locked conditions, the post itself will contact this common edge to further facilitate the prevention of sliding movement of the slider device 31 and track member between the closed condition (FIG. 16) and the opened condition (FIG. 15). Such a dual locking post design provides an added layer of redundancy. This is beneficial should one of the locking posts fail or be inadvertently left in the unlocked condition.

In another alternative embodiment, the locking post could be coupled to the poly bag itself (not shown). That is, the locking post could be mounted to, and protrude outwardly from, the second side panel 25. When the slider device 31 is positioned at the end, and the track members are oriented in the closed position, the second wing 35 could lock and engage with the locking post 37.

While the present invention has been described in connection with the preferred form of practicing it and modifications thereto, those of ordinary skill in the art will understand that many other modifications can be made thereto within the scope of the claims that follow. Accordingly, it is not intended that the scope of the invention in any way be limited by the above description, but instead be determined entirely by reference to the claims that follow.
