Definitions

  • Blister packs are now widely used for medicinal and food supplement tablets and capsules, whereby these tablets or capsules are contained between a normally transparent, flexible plastic sheet, thermoformed so as to define a plurality of pockets, with each pocket being just large enough to receive the shape of the individual tablet or capsule, and a flat aluminium foil, heat sealed to said plastic sheet.
  • the main advantage of this type of packaging is the extended shelf life, due to protection against oxygen and humidity, that it provides for these medicinal tablets and capsules, compared to conventional packaging in bottles and containers. With blister packaging, the tablet or capsule does not get exposed to external air and humidity until such time that the aluminium foil is broken. The aluminium foil is not supposed to be broken until just prior to the user ingesting the tablet or capsule.
  • the second advantage of blister packs is the convenience to the user of being able to carry around in his or her pocket or handbag just one flat and light blister card of tablets instead of having to carry the whole bulky and heavy bottle.
  • the need to carry tablets on one's person applies to many tablets, such as headache, anti-histamine, contraceptive, antacid, anti-inflammatory and heart tablets etc.
  • the object of this invention is to prevent the blister packs of tablets, pills and capsules from being accidentally damaged when individual blister cards are being carried around in pockets, handbags, briefcases. glove compartments etc. Such damage occurs frequently with the present form of blister cards, when other hard objects such as keys, coins, lipstick, pen, comb, spectacles etc., come into contact with the individual blister card, punctures the frangible aluminium foil and thereby exposes the tablet or capsule to the external air, humidity and other contaminants.
  • the present invention consists in a blister pack for tablets or capsules comprising a flexible plastic sheet, thermoformed to define a plurality of open faced pockets each pocket being shaped to receive an individual tablet or capsule, the open faces of the pockets being closed by a sheet of aluminium foil, heat sealed to the plastic sheet, characterised in that hinge means are provided across the pack on a line about which the pack is substantially symmetrical, the two halves of the pack on either side of the hinge being adapted to be folded together with the area of aluminium foil of each said halves overlying the other, whereby the aluminium foil is protected from accidental damage that might be caused by contact with a hard object, resealable fastening means being provided to maintain the pack in a folded configuration. It is preferred that the fastening means be formed integrally with the pack, separate fastening means may however be provided.
  • the hinge means consists in a hinge groove formed by thermoforming and having cuts extending parallel to the groove on either side thereof, the depth of the groove and the lengths of the cuts being selected in relation to the characteristics of the sheet so that when the sheet is folded about the hinge, parts thereof on either side of the hinge will each fold through 90 to lie flat against and in contact with the other part.

  • Figure 28 is a plan view of the hinge of Figure 26.
  • Figure 29 is a cross-sectional view through a thermoformed hinge where the hinge groove depth equals R+T before folding.
  • Figure 30 is a cross-sectional view through the hinge of Figure 29, after folding.
  • the blister card 1 shown in Figures 1, 2, 3 and 4 comprises a sheet of flexible plastic material with a plurality of thermoformed blisters or pockets 2, suitably shaped to receive either round tablets and pills or elongate capsules of medication 3.
  • the tablets, pills or capsules are placed into these pockets and then covered with the aluminium foil 4 which is heat-sealed to the plastic sheet, in order to hermetically seal the medication inside the pockets.
  • the creased or perforated hinge line 5 divides the blister card into two equal halves and enables the blister card to be folded, as shown in Figure 4, with the two pairs of press studs 6 or 7 engaging and thereby securing the blister card in its folded state.
  • the frangible aluminium foil is protected against any accidental puncturing by other objects.
  • Ribs 8 and 9 along the edges of the blister card can be thermoformed into the plastic sheet in order to give the blister card some additional stiffness and flatness.
  • Figures 5, 6, 7 and 8 show another preferred form of the invention where instead of the above mentioned press studs there are a pair of inter-locking cuts 10 and 11 in the edges of the blister card parallel to the hinge line 12.
  • the distance between the two cuts 10 is somewhat greater than the distance between the two cuts 11, so that when the blister card is folded and the edge between cuts 10 is pressed against the edge between cuts 11, the pliable edges will deform and inter-lock, thereby securing the blister card in its folded state, as shown in Figure 8.
  • the hinge 12 shown in Figure 5 is thermoformed into a slightly thinned out ⁇ -shape to facilitate the folding action.
  • One or more ribs 13 at right angles to the hinge line can be thermoformed into the plastic sheet in order to keep the blister card flatter before and after folding.
  • Figures 9 and 10 show two further examples of similar inter-locking cuts. There exist many different shapes of inter-locking cuts that will perform the same basic function of fastening the folded blister card.
  • Figures 11, 12, 13 and 14 show a blister card with two creased hinge lines 14.
  • One of the card's edges parallel to the hinge lines is formed into a channel 15, so as to receive the plain edge 16 and secure it inside this channel when the blister card is folded.
  • Multiple creased or thermoformed hinge lines assist the hinging action and also allow for some longitudinal movement between the two halves of the blister card when the abovementioned plain edge 16 is inserted into and withdrawn from the channel shaped edge 15.
  • Figures 15, 16, 17 and 18 show another preferred form of the invention.
  • the channel shaped hinge 17 is thermoformed and has thinned out walls to facilitate the folding action.
  • a continuous groove 19 is formed along the three edges of one half of the blister card.
  • Grooves 19 and 20 and keys 18 give the two halves of the blister card added stiffness and flatness.
  • Tabs 21 facilitate opening of the folded card.
  • FIGS 19a, 19b, 19c and 19d show another preferred form of the invention.
  • the two thermoformed keys 22 in one half of the blister card press into the two thermoformed grooves 23 in the other half of the blister card.
  • the two pairs of tabs 24 and 25 are located close to the keys 22 and grooves 23 in order to help overcome said frictional resistance with minimum distortion caused to the rest of the blister card.
  • the ribs formed into the tabs 24 and 25 improve the finger gripping action of the tabs.
  • Ribs 26 and 27 along the edges of the blister card are thermoformed into the plastic sheet in order to give the blister card additional stiffness and flatness.
  • the blister card has four rows of blisters for tablets, each row holding seven tablets, one tablet intended for each day of the week.
  • the days of the week are printed adjacent to the corresponding blisters on the aluminium foil that seals the blister card.
  • Figures 20a, 20b, 20c, 20d and 20e show another preferred form of the invention.
  • One half of the blister card incorporates a tongue 28 which engages the cut-out 29 in the other half of the blister card in order to secure the blister card in its folded state.
  • Ribs 30 formed along the edges of the blister card give it additional stiffness and flatness.
  • Figure 20c shows a double creased hinge 31 and alternative single creased hinge 32.
  • Figure 20d shows a thermoformed hinge 33.
  • Figures 21a, 21b, 21c and 2Id show another preferred form of the invention.
  • the two thermoformed keys 34 in one half of the blister card press into the two thermoformed grooves 35 in the other half of the blister card.
  • the thermoformed ribs 36 and 37 along the straight edges and rounded corners provide additional stiffness and flatness to the blister card.
  • the basic function of folding the individual blister card and fastening it in its folded state, in order to protect the frangible aluminium foil against damage, in all these preferred forms of the invention, is identical. It may be necessary for the end-user to open and close the blister pack many times. Therefore the hinge must be durable and, at the same time, it must not be too stiff, so as not to distort the blister pack during folding.
  • Thermoformed groove hinges can be formed into any plastic sheet, whatever the plastic polymer, e.g. polyvinyl chloride (PVC) , polypropylene (PP), polystyrene (PS), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET) etc. or any co-extruded combination of layers of these polymers.
  • PVC polyvinyl chloride
  • PP polypropylene
  • PS polystyrene
  • ABS acrylonitrile butadiene styrene
  • PET polyethylene terephthalate
  • Perforations are not suitable for all plastic polymers. E.g. if the blister pack is thermoformed from a relatively brittle material, such as PS, ABS or PVC, then a perforated hinge will break after only a few closing and opening actions.
  • Creased hinges are also only suitable for ductile polymers with long molecular chains, such as polypropylene or polyethylene.
  • the geometry and function of a thermoformed hinge are explained below:
  • the hinge groove 101 in Figure 22 has a depth that equals the radius R of the groove profile, before folding.
  • the folded blister pack will not be distorted and the two folded sides 104 will be parallel and will make contact along their full length, with no gap between them.
  • this hinge will be much too rigid and the blister pack will distort during and after folding.
  • the depth of the hinge groove 105 can be increased from R to R+H, as shown in Figure 24.
  • the hinge resistance to folding is weakened primarily because the plastic sheet is thinned out further in the deeper groove during thermoforming.
  • the corners 106 will touch before the 180° folding angle is being completed and before the two folded sides 107 have become parallel.
  • the blister pack will distort.
  • thermoformed groove hinge It is desirable to weaken the resistance to folding of the thermoformed groove hinge in order to prevent distortion of the folded blister pack and, at the same time, allow the two folded sides to be parallel and to make contact along their full length, substantially without gaps. This is achieved by the incorporation of cuts 108, parallel and adjacent to the hinge groove 109, on either side of the groove, as shown in Figure 26 and Figure 28. These cuts weaken the hinge's resistance to folding and, at the same time, prevent the premature contact of the corners 106 at a folding angle less than 180°, as was shown in Figure 25. The two folded sides 110 will be parallel and will make contact along their full length, substantially with no gap between them as shown in Figure 27.
  • the type of plastic polymer and the sheet thickness must be taken into consideration.
  • the individual cut lengths LI, L2, ... Ln do not have to be equal. They can be varied in length to suit the size and location of the blisters on the blister pack, as shown in Figure 28, so as to improve flatness of the folded blister pack in its direction of length and width. Any one of the various forms of hinge may be used in conjunction with any one of the forms of fastening means described above.
