Description

WO 2009/150453 PCT/GB2009/050642 1 A MEDICATION CARRIER [0001] This invention relates to a system for discretely packaging a plurality of quantities of one or more fluid or solid substances, particularly, though not exclusively, items of medication. 5 Such a system is devised to meet the needs of patients and carers in the safe, accurate and monitored dispensing of medication both in liquid and solid forms. Liquid medication, apart from the use of individual sachets or blisters, is conventionally supplied to the patient or carer in large containers from which individual doses are dispensed, usually into a measuring spoon or cup from which the patient takes the medicine. It is of the utmost importance that the patient 10 should take an accurate dose of the correct medicine and that there should be no risk of confusion or of cross-contamination between patients should a large bottle of medication be used, perhaps improperly, to dispense the medication to different patients. BACKGROUND 15 [0002] Such a system of accurately and conveniently packaged individual doses of medication, whether in liquid or tablet form, and which is more easily managed in a safe and convenient manner, thus substantially avoiding the aforementioned difficulties, is described and claimed in our co-pending patent application number 0719991.2. In that application there is described a container for discretely packaging a plurality of quantities of one or more fluid or 20 solid substances, and comprising a tray having individual spaced compartments, a plurality of vessels individually removably received within the respective compartments and adapted to contain the substances to be packaged, and a flexible sheet sealingly attached to and across an otherwise open top of each vessel. The sheet is sealingly attached to and across the entire tray and all the vessels therein with perforations to permit selective removal of the vessels 25 individually while at least some of the vessels are retained and remain sealingly closed. The flexible sheet may display printed matter identifying the content of each vessel. [0003] Individual vessels are removable from the tray while all of the vessels, including those removed, remain sealed by the flexible sheet, the perforations permitting easy separation of individual vessels. Thus, a patient can remove the vessels as and when required from the tray 30 and then peel off the individual flexible sheet of that vessel in order to reveal the medication contained therein, whether it be in liquid or tablet form. Ideally, each vessel contains the medication needed to be taken at a particular time of day and since most medication is taken four times a day, the vessels are arranged in the tray in rows of four so that the patient may remove an individual vessel at the appropriate time. 35 [0004] While the system provides a convenient means of storing and dispensing medication, nevertheless a patient may not wish to carry the entire tray around with them if, for example, WO 2009/150453 PCT/GB2009/050642 2 they are intending to leave the premises for a day, perhaps when visiting relatives or friends, and so it is an object of the present invention to provide a temporary storage and transporting carrier such that a number of vessels may be removed from the tray and temporarily contained within a convenient carrier of reduced size when compared with the tray. 5 BRIEF SUMMARY OF THE DISCLOSURE [0005] According to the present invention, there is provided a medication temporary storage and transporting carrier comprising a carrier tray with a closable lid, the carrier tray defining a plurality of apertures each configured to receive one of a plurality of individual sealed vessels, 10 each vessel of complementary lateral dimensions with a peripheral flange adapted to rest upon the carrier tray around one of said apertures with the body of the vessel extending beneath the carrier tray, the lid being closable over the carrier tray to retain the or each vessel therein. [0006] Closure means may be provided to retain the lid in its closed position thus to retain the or each vessel on the carrier tray. 15 [0007] The closure means may be a frictional peg and socket arrangement. [0008] The closure means may be a lip and flexible catch arrangement. [0009] The carrier tray may define four such apertures arranged in a single row thus to carry four such vessels side-by-side. [0010] The carrier tray may define four such apertures arranged in pairs thus to carry four 20 such vessels in two side-by-side pairs. [0011] The carrier tray and lid may be made as a single piece from moulded plastics. [0012] The carrier tray and lid may be made as a single piece from paperboard. [0013] In another aspect, the present invention provides medication storage system comprising a medication temporary storage and transporting carrier as defined above and a 25 container for discretely packaging a plurality of quantities of one or more fluid or solid substances, and comprising a container tray having individual spaced compartments, a plurality of said vessels individually removably received within the respective compartments and adapted to contain the substances to be packaged, and a flexible sheet sealingly attached to and across an otherwise open top of each vessel, the sheet being sealingly attached to and across the 30 entire container tray and all the vessels therein, perforations in the sheet to permit selective removal of the vessels individually while at least some of the vessels are retained and remain sealingly closed. [0014] Said peripheral flanges of adjacent vessels in said container tray may be spaced apart WO 2009/150453 PCT/GB2009/050642 3 whereby the sheet connects each vessel to the container around its entire periphery. [0015] The perforations may coincide with said peripheral flange so that, after removal of a vessel from the container tray, substantially none of the sheet overhangs said vessel. [0016] Alternatively, the perforations may overlap said peripheral flange so that removal of a 5 vessel from the container tray involves breaking said perforations and breaking the adhesion between said overlap from the surface of the container tray, whereby said overlap serves to adhere said vessel to the carrier tray around said aperture. Said overlap may comprise one or more tabs, the perforations otherwise coinciding with said peripheral flange. 10 BRIEF DESCRIPTION OF THE DRAWINGS [0017] Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Fig. 1 is an exploded perspective view of a container for discretely packaging a plurality of quantities of one or more medications in fluid or solid form; 15 Fig. 2 is a perspective view of a temporary storage and transporting carrier made in accordance with the invention; Fig. 3 shows the carrier with four sealed medication containers therein; Fig. 4 is a view of the carrier and the containers, from beneath; Fig. 5 shows the carrier with a closed lid to retain the containers; 20 Fig. 6 is a view similar to Fig. 2 according to a second embodiment; Fig. 7 is a view similar to Fig. 3 of the second embodiment; Fig. 8 is a view similar to Fig. 4 of the second embodiment; and Fig. 9 is a view similar to Fig. 5 of the second embodiment. 25 DETAILED DESCRIPTION [0018] Referring now to Fig. 1, a container for discretely packaging a plurality of quantities of one or more fluid or solid substances such as medication comprises a container tray generally indicated at 10 of a plastics material and formed to define side walls 11 and an array of individual preformed side-by-side compartments 12 each having a base 13 and a common 30 upper platform 14 extending across the tray 10 between the compartments 12. Removably located within each compartment 12 is a vessel in the form of an individual pot 17 for containment of a substance to be packaged. Each pot 17 has an upper peripheral flange 18 which, when the pot is located in the container tray, rests upon and is flush with the platform 14. The shape of the recess defined within each pot 17 is such as to have a curved upper rim 19 at 35 least at one side. Opposite the curved rim 19 in each pot is a straight edge 20. The walls of WO 2009/150453 PCT/GB2009/050642 4 each pot also conform to the shape of the upper rim. With all of the pots 17 in place a pharmacist may place the appropriate medication in each pot either by using a measured pipette for liquid medication or by placing tablets or capsules into the pots for solid medication. [0019] To complete the container a flexible sheet 21 of a non-permeable material having 5 perforations 22 is placed over the filled tray and sealed to the platform 14 and to the flange 18 of each pot 17. The perforations 22 coincide with the outer peripheries of the pots 17, thus to define individual sealed films 23, one across each pot. With the sheet in place the pots may be removed individually by pushing a pot upwards from the base 13 of its associated compartment 12 thus breaking the perforation in the sheet 21 while maintaining the integrity of the sealed film 10 23. The material of the container tray is such as to permit flexibility of the base 13 to ease ejection of the individual pots. However, the line of perforations could overlap the outer peripheries of the upper peripheral flange 18 to some extent so that, as well as breaking the perforations, at least some of the film must be peeled from the platform surface 14 when a pot is removed, leaving a tab of film overlapping the outer peripheral flange 18. 15 [0020] It will be appreciated that once a pot is removed, the sealed film 23 remaining on the flange 18 can then be peeled off the peripheral flange of the pot, whereupon the medication can be taken. Where present, an overlapping tab of the film provides a gripping point to assist its removal from the pot. The curved rim 19 of each pot facilitates the taking of liquid medication. The regions of the flange 18 either side of the curved rim will have sufficient 20 flexibility that they can be deformed to assist in release of the individual sealed films 23. [0021] In this manner therefore, individual pots can be removed whilst the remainder are retained and sealed on the container tray 10. The individual films 23 may be printed, for example, with a time and date and the contents of the associated pot and/or the name of a patient. 25 [0022] Referring now to Figs. 2 to 5, if a patient wishes to carry, in a more convenient manner, four such sealed pots, for example, when leaving home for the day to visit relatives or friends, there is provided, in accordance with the invention, a temporary storage and transporting carrier comprising a flat carrier tray 30 with a hinged and closable lid 31. The carrier is made from a single piece of moulded plastics. 30 [0023] Four, in-line, side-by-side apertures 32 are provided in the carrier tray 30, each of which, as can be seen, is of complementary shape and size to each of the pots 17 removed from the container tray 10 and is therefore of complementary lateral dimensions such that when each pot is inserted into one of the apertures 32 its flange 18 rests upon the carrier tray and is substantially flush with the surface thereof. A frictional peg and socket arrangement 33, 34 is 35 provided to retain the lid in a closed position when required.

WO 2009/150453 PCT/GB2009/050642 5 [0024] Fig. 3 illustrates the carrier with four pots 17 contained thereby with the individual sealed film 23 retaining the contents of the pots. [0025] Fig. 4, which is an underneath view, shows how the body of each pot extends beneath the tray. 5 [0026] Fig. 5 shows the lid 31 in a closed position to retain the four pots in the carrier. [0027] Referring now to Figs. 6 to 9, in a second embodiment the carrier tray 30 and lid 31 of Figs. 2 to 5 are replaced by a carrier tray 40 and lid 41 of different shape to enable the four pots to be carried as two side-by-side pairs rather than four in a single row. This may be more convenient for some users. Otherwise, the embodiment of Figs. 6 to 9 is identical to that of 10 Figs. 2 to 5. Once again, a frictional peg and socket arrangement 43, 44 is provided to retain the lid in a closed position. If required, in both embodiments, the peg and socket arrangement may be replaced by a lip and flexible catch arrangement. [0028] Where a peripheral overlap of the sealing film is provided beyond the peripheral flange 18 of each pot, the adhesive on it may be employed to fix the pot temporarily in the tray 30,40. 15 Such overlap may be complete around the entire periphery of each pot, or it may be in the form of one or more discontinuous tabs, most of the perforations otherwise being coincident with the peripheral flange of the pot. [0029] Whilst the carrier tray is preferably made as a single piece from moulded plastics, nevertheless it may be made from paperboard so as to be disposable if required. 20 [0030] It will be appreciated that a temporary storage and transporting carrier made in accordance with the invention is a convenient accessory for a patient who may wish to carry a smaller number of sealed pots as opposed to the entire container tray 10. Whilst carriers having capacity for four pots have been described and illustrated, nevertheless other numbers are envisaged, for example, just two pots may be sufficient for a short period, say for half a 25 day's medication. [0031] A temporary storage and transporting carrier for medication, in accordance with the invention, increases the likelihood of correct dosages of medicines to be taken at the correct time. Once a pot 17 has been removed from the carrier it is disposed of so that patients and carers can readily determine at any time, which doses have been removed. 30 [0032] The carriers may be manufactured in different colours thus to allow family members readily to distinguish individual medications without opening. However, the carriers can be manufactured in materials which are largely transparent so that the patient and dosage information printed on the individual films 23 may be read without opening the lid. [0033] While the invention has been described and illustrated in relation to the temporary WO 2009/150453 PCT/GB2009/050642 6 storage and transportation of medication, other substances may be contained within the pots and conveniently transported in a carrier of the invention.
