Definitions

  • This invention relates to convex tablets, to the production of such tablets, and to packages in which tablets are sealed in pouches defined by opposed sheets of material.
  • Most tablets are manufactured with essentially the same basic shape of essentially flat broad surfaces. In many instances, such as when the tablets contain some active chemical agent, they are desirably vacuum sealed within sheet-like packaging in sandwich relationship, in such manner that the sheets converge to form a pouch about the tablet defining a perimeter generally corresponding to a circle.
  • Conventional tablet shape is defined in cross- section by essentially flat, parallel broad surfaces, sometimes defining at the circumferential periphery a slight bevel, provided primarily to minimize tablet edge fracture.
  • the unused space which corresponds to wastage, is most apparent when the tablet is relatively thick, the latter to ensure sufficient tablet strength during manufacture and transportation.
  • the conventional cylindrical tablet configuration has been found to exert a strain on the package that causes the seals between the package sheets to rupture, with the result that product shelf life may be reduced and spoilage may occur.
  • tablet packaging is performed by the adhesive bonding of parallel sheets of packaging material, with non-bonded areas defined periodically on the sheets to provide pouches to retain the tablets.
  • the tablets are usually conveyed while resting on their broad surfaces, and reach a chute, where the tablets drop vertically downward and are then conveyed between the package sheets as they are brought together to seal off the pouch area.
  • BE-A-779427 discloses tablets having two broad outer surfaces which are generally opposed to each other and are spaced apart from each other by a continuous rim.
  • Each of the two broad outer surfaces disclosed in BE-A-779427 is a smooth convex shape, resembling a portion of a sphere.
  • a tablet (10) comprising: two broad outer surfaces (12) which are generally opposed to each other, are generally spaced apart from each other, and terminate in spaced-apart surface perimeters (14); and a continuous rim (16) extending transversely between the surface perimeters (14); wherein at least one of the broad outer surfaces (12) is distended convexly away from the other: characterised in that at least one broad outer surface, over at least a majority of vertical planes passing through the centre of the tablet (10) when the latter is disposed with the rim (16) generally vertical, either (a) consists of a central convex region (18) and a peripheral convex region (20) adjacent thereto, the external angle (a) between the central convex (18) region and the peripheral convex region (20) being greater than 180°, or (b) comprises a central region, a peripheral convex region (20") and, between the central and peripheral regions, an intermediate convex region (18"), the external angle between the peripheral convex region (20).
  • both of the broad outer surfaces are distended convexly away from each other thereby defining a tablet having a generally bi-convex configuration.
  • the broad surfaces are symmetrically distended.
  • the continuous rim defines a cylindrical surface which is circular or non-circular.
  • a continuous ridge is preferably defined on the exterior of the or each broad outer surface at the junction of the central or intermediate convex region and peripheral convex region; it is the peripheral convex region which defines the tablet point bend, i.e. the point at which the walls of the pouch containing the tablet are drawn towards adhesive contact with each other.
  • the surfaces of the peripheral convex regions of the opposed broad outer surfaces subtend between them an acute angle, which more preferably is less than 45°.
  • the invention also relates to a sealably packaged tablet which comprises, in combination, a tablet package prepared from opposed package sheets peripherally adhered to each other and defining an air-tight tablet pouch containing a tablet of the present invention as described above.
  • the present packaged tablet utilizes a pouch that can be reduced in size compared with many of those of the prior art while retaining the capability for holding a tablet having equivalent weight and content to those of the prior art.
  • the package may include a plurality of spaced apart pouches each containing a tablet.
  • the present invention also includes a method of preparing a tablet according to the first-mentioned aspect of the present invention, which method comprises providing a tablet die having a configuration complementary to that of the tablet according to the present invention which is to be produced, loading the tablet die with tablet-forming material, and compressing the tablet-forming material within a tablet die form a tablet having the desired configuration.
  • both broad surfaces of the die are concave, and thus a tablet having bi-convex configuration is formed.
  • the die may be configured to correspond in shape to the preferred tablet configurations set forth above.
  • Tablets prepared in accordance with the present invention permit packaging material to be reduced in amount by as much as 20 to 25% in area, while package sheet thickness may be reduced as much as 30%. Also, tablets of the present configuration resist breakage and spalling during manufacture and shipping, and the packaging machinery jamming is reduced due to a corresponding reduction in the incidence of "shimming".
  • the present invention is applicable to tablets for a variety of uses extending from medicinal compounds to household goods.
  • the exact angulation and size of individual tablets will be governed by the materials being formed, although the basic convex configuration is utilized in each instance.
  • a tablet 10 comprises paired broad outer surfaces 12 that extend radially outward generally opposed to each other, and terminate in parallel spaced-apart surface perimeters 14.
  • a continuous rim 16 extends transversely between surface perimeters 14 as shown, and may preferably define a circular cylinder as shown in Figures 1 and 2.
  • both broad surfaces 12 may be convexly extended; however, the invention includes the instance where only one broad surface 12 is convex.
  • the broad surfaces 12, when convexly extended as shown, comprise a central convex region 18 and a peripheral convex region 20 that is located annularly adjacent to it.
  • the convex regions 18 and 20, as shown in Figures 1 and 2, define exterior surfaces that are disposed at an external angle with respect to each other that is greater than 180°.
  • an angle a is shown that is defined by the exterior surfaces of convex regions 18 and 20.
  • the convex region 20 may define a bevelled surface that conforms to the frustum of a cone, in the instance where the tablet 10 is circular in shape.
  • the convex region 18, while graduated at a differing angle of inclination than that of the region 20, may define in one embodiment an essentially conical configuration.
  • the shape of respective convex regions 18 and 20 may accordingly vary, and, for example, as illustrated in Figure 8, convex region 18' may define a shape that is essentially pyramidal, in combination with the essentially frustoconical shape of region 20'.
  • the invention contemplates a variety of shape combinations within its scope, and should not be limited to specific combinations illustrated herein.
  • ridge 22 which, in the illustrations herein, may comprise a circle, as in Figure 1.
  • ridge 22 will depend upon the shape of the tablet 10, and the present invention includes ridges having oval, square, rectangular, and other shapes within its scope.
  • FIG. 3B a packaged tablet is shown which comprises a tablet 10 disposed within a package 24 consisting of paired, opposed packaged sheets 26 that have been peripherally bonded to each other, and, in their non-bonded area, define a package pouch 28 to hold the tablet.
  • Figure 3A illustrates a packaged tablet in accordance with the prior art, and tablet 30 illustrated therein is thus enclosed within a tablet package 32 prepared from paired sheets 34 likewise peripherally bonded to define a central package pouch 36.
  • tablet 30 utilizes essentially flat broad outer surfaces. Both packages utilize an identical angle of taper of the package sheets to the point of sealable engagement. In each instance, an acute angle, labelled ⁇ is defined between respective sheets 26 in Figure 3B, and 34 in Figure 3A. Referring back to Figure 2, the exterior surfaces of peripheral convex region 20 preferably define an acute angle corresponding to angle (3 and are therefore labelled identically, to facilitate the reduction in the size of pouch 28.
  • the taper of sheets 26 and 34 begins at the tablet point bends 38 and 40, which mark the point at which the taper of the packaging sheets is set to occur.
  • the identical angle of taper is utilized, and it can be seen that the tablet of the present invention permits the taper to commence nearer to the centre of the tablet, thereby permitting the pouch 28 to be defined within a smaller area, and correspondingly to define a reduced volume.
  • the configuration of tablet 10 permits the same amount of tablet material to be contained within this smaller pouch, as that contained within pouch 36 holding tablet 30.
  • FIGS 4A and 4B comprising plan views partly in phantom of the corresponding Figures 3A and 3B, it can be seen that the pouch 28 is reduced in area from that of pouch 36 and a corresponding reduction is possible in the overall size of sheet 26 from that of sheet 34. It should be noted that this reduction in packaging material is possible without the requirement of a decrease in the diameter of the respective tablets.
  • the surface perimeter 14 of tablet 10 is equal in size to the surface perimeter 42 of tablet 30, with the difference in the size and location of the respective tablet point point bends 38 and 40, accounting for the decrease in the size of pouch 28 over pouch 36.
  • the sheet material itself may be reduced in gauge, as the overall convexity of the outer surfaces 12 reduces the strain on the sheet materials that is normally imposed at the tablet point bend in the instance where the tablet is flat-faced, as illustrated in Figures 3A and 4A.
  • the size of the obtuse angle that is subtended by the central and peripheral convex regions, determined with the tablet point bend 38 as its apex, is thus less than the corresponding obtuse angle that is disposed with tablet point bend 40 as its apex, in Figure 3A.
  • the package sheet 26 is therefore less likely to rupture than corresponding package sheet 34, due to the configuration of respective tablets 10 and 30.
  • package sheet 34 has conventionally been prepared to a thickness of 0.001 inch gauge (0.0025 cm)
  • package sheet 26 may be utilized at a reduced thickness of 0.0007 inch gauge (0.00178 cm gauge), and provides sufficient package strength and integrity, to resist rupture and premature package leakage.
  • the outer shape of the tablets confers a further unexpected advantage, in the instance where the tablet includes a cleansing composition that operates when the tablet is dissolved to form a cleansing solution, such as in the instance where denture cleansers, toilet bowl cleaners and the like are prepared.
  • a cleansing composition that operates when the tablet is dissolved to form a cleansing solution
  • the tendency is generally for the tablet to come to rest at the bottom of the container, resint on one of its broad surfaces.
  • the surface area of the tablet available for interaction with the liquid in the container is limited, as the surface in contact with the bottom of the container is effectively unexposed.
  • the present tablet configuration presents tapered broad surfaces, that would extend away from the bottom of the container and permit the liquid in the container to make surface contact to accelerate the disintegration of the tablet.
  • the method of preparing the tablet of the present invention comprises the use of tablet dies defining at least one concave broad surface that corresponds in shape to the convex broad outer surface desired in the tablet.
  • tablet dies defining at least one concave broad surface that corresponds in shape to the convex broad outer surface desired in the tablet.
  • either one or both of the broad outer surfaces may be defined in corresponding concavities within the tablet die, so that the appropriately configured tablets may be prepared.
  • tablet preparation does not differ from that of the prior art, as conventional tableting agents may be employed, and conventional forming pressures, etc. may be utilized. It is advisable to prepare the tablets of the present invention with essentially flat rims 16, as this prevents the occurrence of "shingling" that comprises the surface discontinuities that sometimes are formed when the tablet edge is rounded.
  • the tablets of the present invention may vary widely in exact shape, so long as at least one of the broad outer surfaces is convexly extended as described.
  • the broad outer surfaces are symmetrically convex.
  • the exact size of central convex region 18 and/or the intermediate convex region may vary considerably, and may range in size from 20% to 80% as a radial dimension, of the total radial dimension of the broad outer surface 12.
  • the central and/or intermediate convex region is in the range from 30 to 70% of the total radial dimension, and more preferably is in the range from 50% to 65%.
  • the term radial dimension will correspond to the radius when the tablet has a circular plan, and will be the dimension from the axis of the tablet to the periphery in other cases.
  • the location of ridge 22 naturally may vary, depending upon the size of the central convex region.
  • FIG. 5 the variation in the size of the respective convex region is illustrated, as peripheral convex region 20 appears larger than that in Figure 2, while the central convex region 18 is reduced.
  • a known tablet 44 is shown which utilizes broad surfaces 46 each constituted by a single convex surface.
  • the tablet 48 has a single convex broad outer surface 50.
  • This embodiment can be specifically utilized in the instance where a package such as package 52 is employed. In such package, only one of the sheets is expanded and forms a pouch, and thus a flat sheet 54 has adhesively bound thereto a convexly expanded sheet 56, which defines the recess forming the tablet pouch 58.
  • This tablet is not particularly satisfactory for two reasons: firstly only one of the broad outer surfaces is convex, and, secondly, that one convex surface has only a single convex region.
  • Figure 8 of the drawings shows an embodiment somewhat similar to that shown in Figure 1, in which the tablet 10' has two identical broad outer surfaces, with a cylindrical rim 16' extending between their peripheries.
  • a peripheral convex region 20' is frusto-conical in shape, like region 20 in Figure 1.
  • the central convex region 18' is substantially pyramidal in shape.
  • Figures 9 and 10 illustrate further embodiments, wherein the tablet is essentially rectangular in shape.
  • tablet 10 defines paired broad outer surfaces 12", which can be seen to be convex, in similar fashion to surfaces 12 of Figure 1.
  • broad outer surfaces 12" are comprised of intermediate convex regions 18", and peripheral convex regions 20" lying adjacent thereto.
  • the separating ridge 22" may vary in configuration from that of a circle, illustrated as 22 in Figure 1 and as 22" in Figure 9, to that of a rectangle 22" in Figure 10 following essentially in parallel fashion a surface perimeter 14" in Figure 10.
  • the peripheral convex region 20" appears as four triangular subsections equally distributed in the corners of the rectangular perimeter 14", while in Figure 10, peripheral convex region 20" is essentially rectangular and surrounds the intermediate rectangular convex region 18".
  • the tablets of Figures 9 and 10 differ further in the configuration of the rim 16", as it can be seen to vary in thickness from a minimal thickness at the corners of the tablet, to a maximum thickness at the points centrally intermediate the corners.
  • the provision of a tablet in rectangular configuration as shown can be appreciated to make further economic use of the package pouch, as, in the instance where the pouch is rectangular, the shape of the tablet assures efficient utilization of defined space.
  • the other advantages discussed above with respect to the tablet of the present invention are equally demonstrated by this further embodiment, as the convex distention of the broad outer surfaces 12" reduces the strain that is normally imposed upon the package pouch.
  • the tablets prepared in accordance with the present invention may contain a variety of ingredients for various uses, including household and medicinal application.
  • the present tablet configurations are particularly useful in the instance where tablets are prepared for use as, for instance, denture cleansers and toilet bowl cleaners.
  • the tablet-forming material may include active ingredients such as cleansers or pharmaceutical compositions, again depending upon the particular utility of the tablet.
