[0003] Although the above referenced unit dose packages and pill boxes disclosed by the
above referenced patents and published applications may be satisfactory for their
intended purposes, there is a need for a unit dose package of novel construction that
is difficult for a child to open, yet readily opened and closed by an intended end-user,
such as a senior citizen. Preferably, the container includes a blister, blister card,
tray or the like on which numerous items, such as doses of medicine, are individually
secured. The blister, blister card or tray should preferably be able to be slid between
a retracted position in which the items are protected and housed within the package
and a dispensing position in which the blister, blister card or tray extends in an
exposed condition from the package, but remains connected to the package.
[0004] The present invention provides a unit dose package according to claim 1. According
to the invention, the child-resistant and senior-friendly unit dose package has a
hollow container body and a tray with a plurality of items secured thereto for being
dispensed from the container body. The container body has an end with an elongate
opening defined by a rim, and the tray is slidable between a retracted position in
which the tray is located within the container body and a dispensing position in which
the tray extends through the opening of the container body and is accessible by an
end-user. The package includes a separate cap removably securable to the container
body to seal the opening and prevent access of the items on the tray by young children
and the like.
[0005] Optional features of the invention are set forth in the dependent claims. In a preferred
embodiment, the container body and cap are made of plastic, and the engagement of
lugs within slots enables the cap to be secured to the container body. Preferably,
a spring, such as a leaf spring, urges the lugs into a captured position within the
slots. Thus, removal of the cap from the container body requires hand pressure exerted
simultaneously in both downward and lateral directions on the cap. Further, preferably
the tray is a blister card and the elongate opening of the container body is substantially
rectangular corresponding to the end profile of the blister card. A mechanism for
preventing complete removal of the blister card from the container body is also preferably
provided.

[0024] A first embodiment of a package 10 according to the present invention is illustrated
in FIGs. 1-6 and includes a container body 12, a tray or card 14 to which a plurality
of dispensable items 16 are secured, and a cap 18. The body 12 extends between closed
and open ends, 20 and 22, and the cap 18 is securable to the body 12 to seal the open
end 22 and removable from the body 12 to permit the tray 14 to be freely slid through
the open end 22 into a dispensing position. The cap 18 can be repeatedly attached
to and removed from the container 12 until all items 16 have been dispensed from the
tray 14. By way of example, the tray 14 can be a blister card containing doses of
medicine, and a child-resistant, senior-friendly connection can be formed between
the container body 12 and cap 18.
[0025] The hollow container body 12 is preferably made of plastic and is shaped to house
a blister card or the like. Thus, the body 12 can be generally flat and substantially
rectangular, for instance, as illustrated in FIG. 1. The mouth, or finish, 24 of the
container body 12 can form an outwardly tapered neck 26 as best illustrated in FIG.
4 and can include a rim 28 that defines a substantially rectangular, elongate opening
30 through which the blister card or the like can extend. The container body 12 can
be formed as an integral molded piece or can be the assembly of two or more separately
formed pieces. For example, the body 12, or components thereof, can be made by injection-molding,
blow-molding, thermoforming, or like techniques.
[0026] The cap 18 is also preferably made of plastic via injection-molding, blow-molding,
thermoforming, or like technique and includes an end wall 32 and peripheral sidewall
34 depending therefrom. The end wall 32 is substantially rectangular for covering
the elongate opening 30 of the container body 12, and the sidewall 34 is of a size
to closely fit about the finish 24 of the container body 12. Preferably, the cap 18
can be snapped onto the finish 24 and requires multiple simultaneously manipulations
by the end-user to be removed from the container body 12. For example, the container
body 12 and cap 18 can be designed so that removal is accomplished only by the simultaneous
actions of depressing the cap 18 relative to the container body 12 and sliding the
cap 18 laterally relative to the container body 12. See arrow "A" in FIG. 2.
[0027] In the illustrated embodiment of the present invention, the mechanism for creating
the child-resistant, senior-friendly cap-to-container body connection is provided
by a series of cooperating lugs 36 and slots 38. The slots 38 provide pathways along
which the lugs 36 are permitted to travel when the cap 18 is engaged to the container
body 12. As best illustrated in FIG. 3, the lugs 36 extend inwardly from the sidewall
34 of the cap 18, and the slots 38 are formed in an external face of the finish 24
of the container body 12. Alternatively, the lugs can extend from the finish, and
the slots can be formed in the cap.
[0028] In the illustrated embodiment, there are two slots 38 on each side of the elongate
opening 30, and each slot 38 includes an open top 40 through which a lug 36 can pass
and a reversely turned section 42 in which the lug 36 can be captured. Accordingly,
the slots 38 have a substantially "J" or "U" shaped configuration as best illustrated
in FIG. 5. The upper portion of each reversely turned section 42 includes perimeter
walls 44 that prevent movement of the lug 36 both in an upward direction as well as
in lateral directions. A spring or like mechanism 46 exerts a force on the cap 18
and container body 12 so that the cap 18 is resiliently biased away from the container
body 12. Thus, when the lugs 36 are located within the reversely turned sections 42
of the slots 38, the spring 46 exerts a force between the cap 18 and container body
12 that prevents the lugs 36 from escaping the reversely turned sections 42. This
locks the cap 18 to the container body 12 and prevents unwanted removal of the cap
18 by young children or the like.
[0029] Preferably, the spring 46 is a leaf spring or the like and is mounted on the underside
48 of the end wall 32 of the cap 18 so that, when the cap 18 is engaged to the container
body 12, the spring 46 engages the rim 28 of the container body 12. Other types of
springs can be used. An applied cap 18 can only be removed from the container body
12 by depressing the cap 18 against the force of the spring 46 and by simultaneously
sliding the cap 18 laterally relative to the container body 12 so that the lugs 36
exit the reversely turned sections 42 of the slots 38 and escape the slots 38 through
the top openings 40. These simultaneous manipulations are not readily accomplished
by a young child, but can readily be accomplished by an adult.
[0030] After an item 16 is dispensed, the cap 18 can be readily re-applied to the finish
24 of the container body 12 by aligning the lugs 36 of the cap 18 with the open tops
40 of the slots 38. When the cap 18 is pressed onto the finish 24 of the container
body 12, the lugs 36 are automatically directed and snap into the reversely turned
sections 42 of the slots 38. Thereafter, the lugs 36 are retained in this captured
position under the force of the spring 46.
[0031] The tray 14 is preferably a blister card or the like that carries items 16 in separate
blister compartments 50 so that the items 16 can be removed one at a time from the
card 14. The tray or blister card 14 can be made of plastic, paperboard, paper, foil
or the like. In addition, as illustrated in FIG. 4, the tray 14 can include a fold
or hinge 52 that permits the tray 14 to be folded upon itself before being inserted
into the container body 12 through the elongate opening 30.
[0032] A tray locking mechanism is used to prevent complete removal of the tray or card
14 from the container body 12. For example, the tray 14 can be placed in a retracted
position (see FIG. 4) in which the tray 14 is housed within the container body 12.
The cap 18 can be applied to and /or removed from the container body 12 when the tray
14 is in the retracted position. After the cap 18 is removed from the container body
12, the tray 14 is free to slide through the elongate opening 30 to a dispensing position
(see FIG. 6). Preferably, a locking flange 54 or the like extends from a face 56 of
the tray 14 at a distal end 58 of the tray 14 and is prevented from passing beyond
the elongate opening 30 of the container body 12 by an inturned flange 60 extending
from an inner surface of the finish 24 of the container body 12. The blister card
14 can be unfolded to expose the blister compartments 50, while the distal end 58
of the blister card 14 remains captured or tethered to the container body 12. Other
alternative tray locking mechanisms can be utilized.
[0033] In use, the plastic, relatively-rigid, substantially-rectangular package 10 can be
used to store a blister card 14 carrying a predetermined amount of tablets, such as
doses of prescribed or over-the-counter medicines, vitamins, supplements, or the like.
Indicia, such as days, dates, or other information, can be displayed directly on the
card to provide the end-user with reminders as to the rate at which the doses should
be taken. Indicia can also be applied to the front and back of the container body
and to the end wall of the cap. Further, the cap 18 and container body 12 can include
alignment markings, such as grooves 62 that aid the user in properly aligning the
cap 18 with the container body 12.
[0034] The end-user removes the cap 18 by pressing the cap 18 toward the container body
12 and simultaneously sliding the cap 18 in a lateral direction as can be indicated
by arrows or like indicia on the cap 18. After the cap 18 is removed, the end-user
can grip an exposed portion 64 of the blister card 14 adjacent the finish 24 of the
container body 12 and slide the proximal end 66 of the blister card 14 out of the
container body 12. Alternatively, the blister card 14 may be caused to slide out of
the container body 12 via a quick hand flicking motion of the container body 12. When
the distal end 58 of the blister card 14 reaches the elongate opening 30 of the container
body 12, further movement of the blister card 14 is prevented. In this dispensing
position, the card 14 extends from the mouth 24 of the container body 12 and may or
may not require unfolding to permit the end-user to access the blister compartments
50. After one or more tablets 16 are removed from the blister card 14, the blister
card 14 can be refolded and returned to within the container body 12 to a fully retracted
storage position. Thereafter, the cap 18 can be reapplied and snapped into place on
the container body 12. This process can be repeated until all blister compartments
50 are empty at which time the container body 12 and cap 18 can be reused, recycled,
or discarded.
[0035] A second embodiment of a package 110 of the present invention is illustrated in FIGs.
7-17. The package 110 is similar in most respects to package 10 discussed above. For
example, the package 110 includes a container body 112, a tray or blister card 114
to which a plurality of dispensable items are secured, and a cap 118. The body 112
extends between closed and open ends, 120 and 122, and the cap 118 is securable to
the body 112 to seal the open end 122. The cap 118 is removable from the body 112
to permit the tray 114 to freely slide through the open end 122 into a dispensing
position. See FIG. 10. The cap 118 can be repeatedly attached to and removed from
the container 112 until all items have been dispensed from the tray 114.
[0036] The cap 118 is snapped onto the finish 124 of the container body 112 and requires
multiple simultaneously manipulations by the end-user to be removed from the container
body 112. The container body 112 and cap 118 are designed so that removal is accomplished
only by the simultaneous actions of depressing the cap 118 relative to the container
body 112 and sliding the cap 118 laterally relative to the container body 112. See
arrow "B" in FIG. 8.
[0037] A child-resistant, senior-friendly cap-to-container body connection is provided by
a series of cooperating lugs 136 and slots 138. The slots 138 provide pathways along
which the lugs 136 are permitted to travel when the cap 118 is engaged to the container
body 112. As best illustrated in FIG. 9, the lugs 136 extend inwardly from the sidewall
134 of the cap 118, and the slots 138 are formed in an external face of the finish
124 of the container body 112. Alternatively, the lugs can extend from the finish,
and the slots can be formed in the cap.
[0038] There are two slots 138 on each side of the elongate opening 130 of the container
body 112, and each slot 138 includes an open top 140 through which a lug 136 can pass
and a reversely turned section 142 in which the lug 136 can be captured. Accordingly,
the slots 138 have a substantially "J" or "U" shaped configuration as best illustrated
in FIG. 9. The upper portion of each reversely turned section 142 includes perimeter
walls 144 that prevent movement of the lug 136 both in an upward direction as well
as in lateral directions. A spring or like mechanism 146 exerts a force on the cap
118 and container body 112 so that the cap 118 is resiliently biased away from the
container body 112. Thus, when the lugs 136 are located within the reversely turned
sections 142 of the slots 138, the spring 146 exerts a force between the cap 118 and
container body 112 that prevents the lugs 136 from escaping the reversely turned sections
142. See FIG. 13. This locks the cap 118 to the container body 112 and prevents unwanted
removal of the cap 118 by young children or the like.
[0039] The spring 146 of the package 110 has an H-shaped configuration and is curved, or
bowed, along its length. See FIG 17. The spring 146 is mounted on the underside 148
of the end wall 132 of the cap 118 and is captured thereto by the lugs 136 and abutments
160 of the cap 118. When the cap 118 is secured to the container body 112, the spring
146 applies a force to lock the lugs 136 within the slots 138. See FIG. 13. When pressure
is exerted on the cap 118 as shown by arrow "C" in FIG. 14, the spring 146 flattens
thereby permitting the lugs 136 to exit the slots 138. Upon removal of the cap 118
from the container body 112, the spring 146 automatically and resiliently returns
to its original and memorized bowed configuration. See FIGs. 15 and 16.
[0040] A cap assembly is illustrated in FIG. 17. In this embodiment, the cap 118 is simultaneously
molded with the spring 146 in the same mold and of the same material. Upon removal
of the cap assembly from the mold, the cap 118 is connected to the spring 146 via
an arm 162. The arm and spring 146 can be pivoted as shown by the curved arrow in
FIG. 17 to locate the spring 146 and arm 162 within the cap 118. Alternatively, the
arm can be broken away from the cap 118 and spring 146, as shown in phantom in FIG.
17, and discarded. Thereafter, the spring 146 is inserted into the cap 118 beyond
the lugs 136.
[0041] The tray 114 is preferably a blister card that carries items in separate blister
compartments 150 and that includes one or more end blister compartments 164. See FIGS.
10 and 11. The compartments 164 extend laterally to a greater extent on the card 114
relative to compartments 150. Accordingly, the compartments 150 fit between a pair
of posts 166 extending within the container body 112 and permit the card 114 to be
positioned to the dispensing position shown in FIG. 10. However, the compartments
164 do not fit between the posts 166, thereby capturing the card 114 to the container
body 112.
[0042] In addition to the posts 166, the container body 112 also includes a spine 168 extending
centrally within the container body 112 between the blister compartments 150. The
spine 168 and posts 166 rigidify the container body 112 and prevent unintended compression
of the container body 112. However, since the posts 166 and spine 168 extend from
only one side of the container body 112, the card 114 is permitted to slide relative
to the posts 166 and spine 168 within the container body 112 between the retracted
position and the dispensing position.
