[0001] The present invention relates to medicine packs.
[0002] Medicines are available in a variety of forms including, tablets and capsules. Tablets
and capsules are traditionally packaged in bottles or containers, although the use
of blister packs is now also commonplace. The advantages of blister packs over traditional
bottles or containers include; maintaining the sterility of the medication; easy visual
determination of the number of doses consumed and the number of doses remaining; and
the ability to provide information on the blister pack regarding the medication itself
and the time or day that the medication is to be taken by the patient.
[0003] Prior art blister packs have a front that is manufactured from a plastics material
which has a number of raised blisters formed thereon for retaining individual doses
of medication. The back of the blister pack is manufactured of a metal foil enabling
the medication to be punched through the foil by applying finger pressure to the blister
from the front. The back of the blister pack has the expiry date and the manufacturer's
batch number printed thereon.
[0004] Some blister packs, known as calendar packs have information regarding the day on
which the medication is to be taken printed on the back. Calendar packs may also have
indicators (e.g. arrows) printed on the back to assist the patient in taking the correct
dose on the correct day. The day indicator is also helpful in remembering whether
the medication has in fact been taken on any particular day.
[0005] Even with the provision of day and other indicators on the back of the blister pack,
some patients, especially the old, seriously ill, disabled or mentally ill, find it
difficult to keep to a strict medication regime. For example, the elderly may have
difficulty in reading the back of a calendar pack or may experience difficulty punching
individual doses of medication through the foil backing owing to the small size of
the blisters.
[0006] This situation is worsened when there are a number of different medicines to be taken
at different times of day and where the pharmacist dispenses "generic" medicines that
have different packaging to previously taken equivalent medicines.
[0007] To address some of the above problems, daily, weekly or monthly home medication packs
are now available. A home medication pack is a self-assembly blister pack. The pharmacist
places individual doses of medication into open blisters of a pre-formed blister sheet
before sealing the doses inside the blisters using an adhesive backing foil. The blisters
of a home medication pack are larger than those of a normal blister pack, so that
more than one dose of medication can be put into each blister. Thus, a made-up home
medication pack may have an array of blisters corresponding with days, times or weeks,
with each blister containing the correct medication for the correct time for each
day.
[0008] Home medication packs have been used successfully for training patients to stick
to a complex medication regime. They also provide a convenient reference that carers
can use to monitor or advise the patient regarding their compliance.
[0009] Some home medication packs come in a foldable format for protecting the blister pack
and for providing additional areas for displaying information (e.g. pharmacy labels)
regarding the medication.
[0010] Figure 1 of the drawings shows such a pack 10 comprising three leaves 12, 14 and
16, two of which 12 and 14 retain the blister pack 18 and the third 16 provides a
protective cover. The first leaf 12 has areas 20 for affixing pharmacy labels 22.
The third leaf 18 has apertures 24 therein to receive the blisters of the blister
pack. The back of the third leaf 16 is has self-adhesive layer 26 thereon which is
selectively exposable by peeling off a peel-away sheet (not shown). The back of the
second leaf 14 has apertures 27 therein which are covered by a foil sheet 28, which
is self-adhesive.
[0011] To use the home medication pack 10, the peel away sheet is removed from the back
of the third leaf 16 and the blister sheet 18 is stuck thereto. The pharmacist then
fills each blister with the correct medications for each time of each day and folds
the second leaf 14 over the third leaf as denoted by arrow A.
[0012] Figure 2 shows the assembled home medication pack 10 from above. The blister sheet
18 is sandwiched between the foil 28 and the third leaf 16 thereby retaining the medication
doses in the blisters of the blister sheet 18.
[0013] It is difficult to align the blisters of the blister sheet 18 with the apertures
of the third leaf 16 without accidentally sticking the blister sheet 18 in the wrong
place. This can be frustrating and costly.
[0014] Additionally, it is difficult for the pharmacist to put the medication doses in the
correct blisters, because the day and time information corresponding with each blister
pack is printed on the side of the pack that is not visible at the time. This problem
can be frustrating and time consuming to overcome.
[0015] Furthermore, the folding and sticking operation can be awkward, and may sometimes
lead to spillage of medication doses resulting in the medication pack having to be
re-filled or discarded.
[0016] An object of the invention is to provide an improved medication pack.
[0017] Accordingly, a first aspect of the present invention provides a folio for a medication
pack for retaining a blister sheet; the folio comprising in an open position; first
and second adjacent leaves and a third leaf; the first leaf having apertures therein
for receiving blisters of the blister sheet; the second leaf having apertures therein
covered by a sheet material, the sheet material having an adhesive layer thereon,
whereby when the folio is in a closed position with a blister sheet in place, the
adhesive layer seals the sheet material to the blister sheet and adheres the first
and second leaves to one another with the apertures of the first and second leaves
corresponding.
[0018] According to a second aspect of the present invention there is provided a method
for assembling a folio for a medication pack for retaining a blister sheet; the folio
comprising; first and second adjacent leaves and a third leaf; the first leaf having
apertures therein for receiving blisters of the blister sheet; the second leaf having
apertures therein covered by a sheet material, the sheet material having an adhesive
layer thereon; wherein the method comprises the steps of; inserting the blisters of
the blister sheet into the apertures of the first leaf; exposing the adhesive layer
of the second leaf; and folding the second leaf on top of the first leaf; so that
the adhesive layer seals the sheet material to the blister sheet and adheres the first
and second leaves to one another with the apertures of the first and second leaves
corresponding.
[0019] Preferably, the folio of the medication pack is manufactured of cardboard. Alternatively,
the folio may be manufactured of a plastics material. Additionally, the folio may
be laminated to make it more durable and/or water resistant.
[0020] The blister sheet is preferably manufactured of a plastics material. Preferably,
the blisters are vacuum formed although injection-moulding techniques may be employed
to achieve the same result. The plastics material is preferably transparent or translucent
for easy visual determination of the medication doses contained therein.
[0021] The folio is folded twice to form three leaves, although an additional fold may also
be present to define a spine. The spine is preferably wider than the height of the
blisters of the blister sheet. Most preferably the folds are oriented such that the
folio folds in a Z-wise manner. Most preferably, the first leaf is located between
the second and third leaves.
[0022] The apertures of the first leaf preferably correspond with the blisters of the blister
sheet such that the blister sheet can be engaged with the first leaf. Additionally,
the first leaf may have markings thereon for relating each blister with a time and/or
day for the medication regime. Preferably, the markings are arranged in a grid-like
fashion for easy interpretation. Preferably also, markings are provided on both sides
of the first leaf, one set visible during normal use, and the other set for assisting
the pharmacist in making up the medication pack.
[0023] Areas may be provided on any part of the folio for displaying information relating
to the patient and/or the medication. Areas may also be provided for affixing pharmacy
stickers to the first leaf.
[0024] The folio is preferably adapted to receive a blister sheet having a certain number
of blisters thereon. The number of blisters may relate to the medication regime, for
example:
[0025] A "weekly" pack may contain seven blisters, i.e. one for each day, or multiples of
seven blisters if different medications are to be taken at different times of the
day. For example, the medication pack may have 14 blisters for a week long course
of morning and night medication, or 28 blisters for a week long course of morning,
lunch, dinner and bedtime medication.
[0026] A "daily" pack may have a plurality of blisters corresponding to the number of doses
of medication to be consumed. Other convenient pack arrangements, e.g. "monthly",
"bi-weekly", "quarterly" etc. can be easily worked out.
[0027] The apertures of the second leaf preferably correspond with the apertures of the
first leaf when folded together.
[0028] The sheet material covering the apertures is preferably adapted to rupture of tear
upon application of finger pressure to the blister or the sheet material. The sheet
material is preferably a metal foil, although paper or plastics materials may also
be used. The sheet material may be permanently affixed to second leaf. Where the sheet
material is permanently affixed to the sheet material, it may be affixed by way of
an adhesive, heat-sealing or welding. Where a welding process is used, it may be an
ultrasonic welding process.
[0029] The sheet material has an adhesive layer thereon, which may be selectively exposable
by way of a peel-off cover sheet.
[0030] The third leaf is preferably arranged to fold over the blisters of the blister pack.
Such an arrangement may be provided to protect the blisters and/or the doses of medication,
and/or to protect the modesty of the patient, who may not wish his or her medication
to be easily visible.
[0031] A preferred embodiment of the invention shall now be described, by way of example
only, with reference to and as illustrated in the accompanying drawings, in which:
Figure 1 shows a perspective view of a prior art medication pack;
Figure 2 shows a plan view of a prior art medication pack;
Figure 3 shows a front view of the invention;
Figure 4 shows a rear view of the invention; and
Figure 5 shows a plan view of the invention.
[0032] Referring to Figure 3 of the drawings, a medication pack 30 is shown comprising a
folio 32 having 3 folds 34 therein defining a first 36, second 38 and third 40 leaf,
in addition to a spine 42. The first leaf 36 is located between the second leaf 38
and the spine 42. The first leaf has a plurality of apertures 44 therein.
[0033] The apertures are arranged and displayed in a grid 46 to make it easy to determine
the time and day on which each medication does (not shown) is to be taken. For convenience,
the grid 46 is divided into four columns denoting breakfast, lunch, dinner and bedtime
respectively, and seven rows - one for each day of the week. The first leaf 36 also
has areas 48 for affixing pharmacy stickers.
[0034] The second leaf 38 of the folio 32 also has apertures 44 therein. The apertures 44
are blocked by a metal foil 50 which is stuck onto the rear surface of the leaf 38.
The second leaf 38 additionally has an medication identificaton chart 52 printed thereon,
for use by the pharmacist.
[0035] The third leaf 40 has a number of areas 48 defined for affixing additional pharmacy
stickers (not shown). The spine 42 has an area 54 for displaying manufacturer or patient
information.
[0036] Figure 4 of the drawings shows the self-adhesive layer 54 on the second leaf 38 of
the folio 32. The self-adhesive layer 54 is exposable by removing the peel-off layer
56 affixed thereto.
[0037] The first leaf 36 has a grid 58 thereon that helps the pharmacist to put the correct
medication into the correct blister. The spine 42 has an area 60 thereon for displaying
patient information. The third leaf 40 has areas thereon for displaying manufacturer
information 62 and instructions 64 for using the pack 30.
[0038] Finally, Figure 5 of the drawings shows the pack 30 in plan view, and illustrates
how the blisters of the blister sheet 36 protrude through the apertures of the first
sheet 36 and are protected by the third sheet 40. The spine 42 is approximately the
same width as the blisters 68. The self-adhesive foil layer 54 seals the back of the
blisters 68 in addition to fixing the margin 70 (the area surrounding the blister
sheet 66) of the second leaf 38 to the first leaf 36.
[0039] Medication doses 72 are removed from the medication pack 30 by pressing them through
the foil layer 54 via the apertures 48 of the second leaf 38. This is accomplished
by applying finger pressure to a desired blister 68 as indicated by arrow B.
