NVENTORZ KJGLL MOE- 6.11M? #fiwou I ata DISPENSERS PREFERABLY FOR MEDICAL- PREPARATIONS IN TABLET FORM This invention relates to a dispenser preferably for medical preparations in tablet form.

In packages for medical preparations in tablet form, of the type that shall be taken at certain times it is known to portion the preparations in so-called blister packages which have time indications printed on them. This system is adapted precisely to the preparation to be packed thereinto and is bound to the intervals determined by the manufacturer at the construction of the packaging.

The purpose of the present invention is to provide a dispenser for tablets and other medical preparations, which is to be filled according to the prescription made by the doctor in each particular case. The characteristic features of this dispenser are that the dispenser has at least one cover and comprises a number of replenishable compartments or spaces which corresponds to the number of times .the medical preparation is to be taken during a certain time, markings at said compartments or spaces showing the time the contents thereof is to be taken, snap-action means permitting a stepwise movement of the cover, each movement of the cover by one step resulting in uncovering of onecompartment, and means for detachable fixation of a card or like means showing the type and prescribed dosage of the medical or other preparations.

For better understanding the invention will be more fully described in the following with reference to the accompanying drawing illustrating three embodiments of the dispenser in accordance with the invention.

In the drawings:

FIG. 1 is a top plan view of the first embodiment of the dispenser;

FIG. 2 is a section of the dispenser taken on line II-Il in FIG.

FIG. 3 is a top plan view of the second embodiment of the dispenser;

FIG. 4 is a section of the dispenser taken on line IV-IV in FIG. 3;

FIG. 5 is a side view of the third embodiment of the dispenser;

FIG. 6 is a top plan view of the dispenser shown in FIG. 5; FIG. 7 is a longitudinal section taken on line VII-VII in FIG. 6;

FIG. 8 is a fragmentary portion of a longitudinal section taken on line VIII-VIII in FIG. 6; and

FIG. 9 is part of a cross section taken on line-IX-IX in FIG. 6.

The dispenser illustrated in FIGS. 1 and 2 is primarily intended for use by patients for whom a large amount of a medical preparation is prescribed at one and the same time. It comprises a body 1 and covers 2. The dispenser body is divided This type of dispenser is intended particularly for persons who for a long time haveto take several tablet preparations, for instance one type of tablets once a day, another type of tablets at meals and perhaps a third type of tablets at night. The dispenser prevents a double intake and simultaneously permits checking that the respective preparations have been taken in the prescribed order. i

The embodiment of the dispenser illustrated in FIGS. 3and 4 is primarily intended for use in hospitals and like institutions where medical'preparations are handed out daily, It is meant to replace the cups and like receptacles hitherto used. In this embodiment, 15 designates the dispenser proper which has four aligned compartments 16. The dispenser is closed by a cover 17 which slides in guides of the same kind as do the covers in the earlier embodiment. The end wall 18' has a boss 19 which coacts with recesses 20 at the underside of the cover so that when the cover is extracted a clicking noise is heard each time a partition 18 is passed. In this embodiment also the underside of the dispenser body has an elongate recess 21 provided therein to accommodate a card or like means showing the name of the patient and the type and prescribed dosage of the medical preparations contained in the dispenser.

The third embodiment of the dispenser shown in FIGS. 5-9 is a modification or development of the first embodiment and can be disassembled altogether to permit efficient cleaning thereof. The dispenser body designated 1' comprises three parts, namely the body proper which is divided into compartments 3'by partitions 4, end walls 4' and a bottom 101, a top piece 103 having a groove 102 for the sliding covers 2' which are equipped with snap action latches, and a bottom piece 12'. Along the outer longitudinal edges the top piece 103 has downwardly extending projections 104 with grooves 105 therein for accommodating rib-shaped projections 106 at the edges of the body 1'. Raised ribs 108 spaced the same distance apart as the transverse partitions and end walls of the body 1' extend between the edge portions 107 of the top piece 103. The ribs 108 and the portions 109 in which the grooves 102 for the sliding covers 2 are provided, together constitute a lat tice which corresponds to the partitions 4 and end walls 4 of the body 1'. One short end of the top piece 103 has an end abutment 110 and at the opposite end of the top piece 103 there is arranged a locking device in the form of a boss 111 engaging the edge of the body, as will appear from FIG. 8. The

into a plurality of compartments 3 defined by partitions 4. The

compartments are arranged in seven rows 5-one for each weekday-and in each row there are four consecutive compartments, for instance for breakfast, lunch, dinner and supper. Extending transversely across the rows 5 are ribs 7, and the facing edges 8 of said ribs together form guide grooves for the sliding covers 2. The facing rib edges 8 should suitably be arranged in such a way that they form dovetail grooves, and the edges of the covers 2 should be given a conforming shape. To provide controlled extraction of the covers, preventing too far an extraction thereof, a boss or like member 9 is provided at the upper edge of the extreme end wall 4' and the covers have recesses 10 at their undersides, into which snaps the boss 9 at the end wall. As will appear most clearly from FIG. 1

where the uppermost cover 2 is shown removed from the dispenser body in longitudinal section, there is such a recess 10 at a level with each partition '4. At the bottom of the dispenser body is made an elongate recess 11 which is covered by a transparent plate 12. This plate 12 is detachable and intended to cover a prescription card showing the prescribed dosage the amount of, and the intervals when, the respective preparation is to be taken.

bottom piece 12' which corresponds to the plate 12 in the embodiment according to FIGS. 2 and 4 is made of transparent material and at the longitudinal edges has grooved projections 102 which are intended for coaction with ribs 113 at the lower edges of the body 1'. The bottom'piece 12' which is intended to cover the prescription card or like means to be mounted at the underside of the dispenser, also has abutments and a locking device to prevent unintentional displacement. In other respects this embodiment substantially agrees with the embodiment first described.

The embodiments of the dispenser described above and illustrated in the drawings may to advantage be made of plastics material in bright colours with the covers or parts thereof in transparent material so that the covers need not be opened for checking the contents of the dispenser.

To provide easy-to-read time indications the text should be given a colour heavily contrasting with the remaining material, or varying colours, and be embossed or raised in relief. As will be seen from FIG. 3, the time indications may appear in conventional characters as well as in braille. To make it easier for persons of reduced eyesight to find the correct time indication the earlier mentioned ribs 108 in FIGS 5-9 are raised with regard to the ribs 109. Besides, the ends of the covers 2' are provided with upturned finger grips.

It is obvious that the number of compartments as well as their mutual disposition and relative size can be varied. For practical reasons, however, the number of embodiments should suitably be restricted to two main types one for a whole-week use according to FIGS. l-2 and 5-9, and one for one-day use according to FIGS. 3-4, which will satisfy normal needs.

The dispenser according to the present invention increases the possibilities of the patient to adhere to the doctors prescription and makes it possible for doctors or relatives to check that the prescription dosage is strictly followed. The

risk of a double intake of medical preparations is highly reduced, as already mentioned, and the risk that another doctor than he who made the original prescription will prescribe synonymous preparations or such preparations as can lead to unfavourable effects in connection with those already prescribed, is eliminated because the prescription card is always available at the rear face of the dispenser. The dispenser according to the present invention is primarily intended for use by old patients and others who can adhere only with difficulty to the conventional medication prescribed.
