ABSTRACT:

BACKGROUND
1. Field of the Invention
This invention relates to a child resistant package that offers resistance to removal of articles contained therein when a panel of the package is fully opened or closed and permits removal of the articles only when the panel is properly aligned.
2. Discussion of Related Art
Conventional child resistant packages and dispensers are well known in the art. For an example, U.S. Pat. No. 3,610,410 to Seeley discloses a tamper proof reclosable sliding panel display blister package that has a working panel
25
with a narrow slide panel
31
attached thereto. See
FIG. 3. A
back panel
23
has a removable portion
32
defined by a perforated line
32
a
to provide a port
34
for discharging articles contained within the blister packaging
19
.
As illustrated in
FIG. 4
, the sliding panel
31
can be withdrawn by bending the extending tab portion
51
rearwardly, which causes the crease
27
to serve as a hinge. The sliding panel
31
thereby moves in and out of the enclosure
44
and is retained under platform
39
and between skirts
41
. When the panel
31
is in the fully closed position, as in
FIG. 3
, the articles contained in the blister packaging are prevented from passing through the port
34
. However, when the slide panel
31
is opened or slid in a left to right direction of
FIG. 3
, the articles within the blister packaging are able to pass through the port
34
.
U.S. Pat. No. 2,971,638 to Allison et al. discloses a dispensing container having a pair of front and back sheets
20
a
and
21
a
arranged in facing relation with each other with an inner sheet
22
a
sandwiched there between. The front sheet
20
a
has an elongate opening
24
a
with numerous removable stop elements
25
a
detachably secured within the opening. Outlet openings
27
a
are formed in the back sheet
21
a
.
The inner sheet
22
a
is slidably retained between the outer sheets
20
a
and
21
a
. Formed in the inner sheet
22
a
are a plurality of depressed portions
30
a
, each of which defines a protrusion projecting forward into the front sheet opening
24
a
and a recess opening rearward towards and closed by the back sheet
21
a
. In other words, the recesses
30
a
are all closed by the back sheet
21
a
and the inner sheet
22
a
with the pills
31
a
contained therein being mounted for longitudinal shifting movement therein.
Accordingly, the inner sheet
22
a
is shiftable longitudinally until the recess portions
38
engage an undetached stop element
25
a
. This shifting places the upper most recesses
30
a
in registry with the outlet aperture
27
a
so that the pills may be discharged from the device through the apertures.
U.S. Pat. No. 2,497,455 to Johnson discloses an article dispensing container having side walls
18
and
21
, a bottom wall
20
, a top wall
22
, and inner wall
25
. Apertures
28
and
29
are formed in the top wall
22
and inner wall
25
, respectively. The container is filled with articles, such as tablets, and the like. In a closed state, the apertures
28
and
29
are offset from each other to prevent the articles from being removed.
In order to dispose the articles, a rear end wall
26
, is pivoted inwardly, as shown in
FIG. 4
, to move the inner wall
25
so as to align the aperture
29
with the aperture
28
of the top wall
22
. The container can then be turned upside down to remove the articles.
SUMMARY OF THE INVENTION
An object of this invention is to overcome the above-discussed drawbacks of the conventional child resistant packages and dispensers.
Another object of this invention is to provide a unique package that is child resistant, yet user friendly. The package is structured so that a panel of the package obstructs removal of the articles being held within. In particular, when the package is fully opened or fully closed, the panel offers resistance to the removal of the articles contained therein. Only when the panel is in an aligned position do holes in the panel properly align so that the articles within the package can be removed. Each article is sandwiched between top and bottom base portions of the package such that the panel can slide in-between when the package is opened or closed.
