Definitions
- THIS INVENTION relates to the prevention of bounce occurring when small objects are loaded into pockets into which they may be subsequently sealed.
- the invention is particularly well-suited, although not exclusively so, to preventing solid medication doses, such as tablets, from bouncing when falling into a pocket formed by the cavity of a blister of a blister sheet.
- the provision of prescribed medication to a patient by means of a pre-loaded blister package is commonly used to enable the patient to carry several days supply of prescribed doses of medication.
- the doses are prescribed by a doctor and appropriately packaged by a pharmacist to provide the patient with a sealed blister sheet having individual blisters marked with the days and times at which the doses in each blister are to be administered to the patient.
- the program determines which blister of the blister sheet is to be loaded at a particular moment with a particular prescribed medication.
- the blister sheet is normally loaded while inverted and has its blisters extending downwardly into respective openings provided in a horizontal support table.
- the table can be indexed horizontally in its own plane by a mechanism to bring each blister in turn to a pre-arranged loading position at which the appropriate medication dose selected from one of the containers can be released into its cavity.
- the blister sheet is normally made from a plastics material which has a natural resilience, and it is convenient to rely on gravity to transfer a dose from a selected storage container to the blister cavity.
- the natural resilience of the blister sheet can cause a dose to bounce back out of the blister cavity if it is the first dose to be placed in it, and there is also a risk that the descending dose will impact on a dose already in the cavity and damage one or both doses as a consequence.
- the distance through which the dose drops from the underside of the container should be made as small as is practical. However there is a limit to the reduction of this distance if there is to be no risk of a dose bouncing out of the cavity interfering with the operation of the indexing mechanism.
- An object of this invention is to reduces the risk of problems occurring during loading of doses or other hard objects into a blister cavity.
- apparatus for loading individual cavities of a blister sheet with small hard objects released into the cavities from above includes: first means for locating individual containers holding the objects at a level above the position of the blister cavity to be loaded; second means for releasing an object from the container so that it follows a path leading downwards towards the cavity; and, third means located in the path of descent of the object and acting to retard its rate of descent to an acceptable level (as below defined) before it reaches the cavity.
- acceptable level referred to above, is a level at which a released object will not bounce back out of the cavity nor will its impact on other objects already loaded into for different objects to be loaded into the blister cavity.
- the third means is formed by a deflector which is struck by the object during its descent to absorb part of its momentum and thus slow it down.
- the lower end-portion of the opening is shaped to direct an object descending through it towards a side- wall of the blister cavity
- apparatus for loading cavities of a blister sheet with prescribed doses of medication mcludes: a support table provided with means for positively locating respective blisters of the blister sheet at a level spaced beneath and displaced horizontally with respect to a position at which dose-storage containers can be located, and a deflector positioned between the storage containers and the table to deflect a dose falling from the storage container laterally towards a blister cavity intended to receive it.
- the deflectors referred to immediately above are provided by the internal surfaces of respective axially parallel bores formed through a relatively thick and horizontal plate located between the level of the blister sheet on the table, and the level of the dose-discharge position of the container.
- the portion of the lower end-portion of the bore opposite the side first struck by a descending tablet may be rebated to avoid the risk of tablets stacking up against one side of the cavity and possibly interfering with the correct operation of the apparatus.
- an indexing mechanism of the table may be operated to bring the cavity of the blister to be loaded and its associated deflector, to a position at which the deflector is located beneath the lower end of a storage container from which the dose is to be released.
- the dose then strikes the deflector during its descent, and its momentum is reduced as a consequence.
- the deflection also preferably deflects the descending dose towards a side- wall of the selected blister. Impact with the side wall slows down the descent still further so that the risk of the descending dose damaging itself or other doses which may already be in the blister is reduced still further.
- FIGURE 1 is a perspective view from above of a relatively thick plate penetrated by an array of axially-parallel bores inclined to the plane of the plate and providing one form of deflecting means;
- FIGURE 2 is a diagrammatic plan view of the plate of figure 1 ;
- FIGURE 3 is a side view of the plate of figure 2;
- FIGURE 4 is an end view of the plate of figure 2;
- FIGURE 5 shows diagrammatically, and to a greatly enlarged scale, the path of descent of a dose through one bore of the plate, the dose being released from a dose-storage container above the plate and striking against a deflecting surface provided by the interior wall of the bore so that the dose is deflected towards the upper internal wall of a blister cavity beneath; and,
- FIGURE 6 shows a modification of figure 5 and where identical parts bear identical reference numerals but they are primed, and the lower end of the bore is rebated.
- FIG. 1 The support table 30 of figure 5 is provided with openings 14 for the reception of respective blisters 15 of an inverted blister sheet 12 moulded from a resilient plastics material and placed blistered-side down on the table 30.
- Figures 1 to 4 show a flat thick nylon plate 1 formed with an array of identical cylindrical and axially-parallel bores 2 inclined at an angle to the plane of the plate of about sixty degrees. The plate 1 is slightly less than two centimeters thick. The diameter of each hole is slightly more than sixteen millimeters. None of these dimensions or angles is critical and are only given as one example of the invention.
- Figure 5 shows one of a number of dose-storage containers 6 located at a level spaced above the plate 3 and at a dose-discharge position vertically above the upper end of a bore 2.
- a mechanism (not shown) at the lower end of the container 6 and controlled by a computerized control system (also not shown) allows a dose to be released from the container 6 in response to a control signal generated by the system and controlling operation
- the dose strikes against the inside wall of the bore intermediate its ends, at a location 7.
- the distance through which the dose falls before striking the location 7 is found empirically and ensures that the momentum of the dose 4 is insufficient to cause damage to I when impacting on the location 7. This fall distance may be varied in the apparatus to achieve this result and it will be found empirically and changed to suit different types of dose.
- the contact of the dose with the location 7 acts to reduce the vertical momentum of the dose 4 and deflects it down the inclined bore 2 towards its lower end.
- the dose leaving the lower end still has a horizontal component of velocity so that it impacts on the side wall of the blister cavity positioned beneath the lower end of the bore 2 and associated with it. .
- a rebate 100 is provided on the side of the lower portion of the bore 2 opposite the location 7.
- This rebate 100 serves to accommodate overflow of doses within the cavity of a blister being loaded, and also to prevent doses from stacking up at one side of the blister and possibly blocking the lower end of the bore 2.
- the invention is capable of being used in any apparatus where it is required to reduce the velocity of descent of hard solid objects which might otherwise free-fall with an undesirably high velocity.
- the deflecting bores of such apparatus may, for example, be used to reduce the velocity with which tablets or other solid medication doses are inserted into respective single dose blisters, or to orientate the dose to a desired position required for entry into a blister .
