Field of the Invention
[0001] The present invention relates to a reinforced child resistant spout of a package.
Background of the Invention
[0002] Child resistant packaging is understood to be an important concept for preventing
inadvertent access by children, for example, to potentially dangerous liquid or dry
products. The packaging industry is in need to prevent children the access to detergent
tablets which may be ingested by children. This means that especially the apertures
to the interior of the packages have to be protected from opening by children. Detergent
compositions formed in non particulate solids such as bars or tablets or briquettes
are known in the art. In the following, the term "tablet" will refer to any form of
non particulate solids. The detergent tablets available on the market are generally
sold packed in containers in a loose way or individually wrapped in bags.
[0003] Due to the difficulty in opening child resistant packages, many persons, especially
elderly adults which may also have impaired strength and dexterity, tend to prefer
a non-child resistant package. Alternatively, when dangerous products are purchased
in child resistant packages by adults, the child resistant package is often not reclosed
in order to defeat the child resistant feature. As a result, the danger of child poisonings
may increase in the homes.
[0004] The aforementioned problems are generally recognised in the packaging industry. The
co-pending European patent application No. 95308468.8 describes a package for containing
and dispensing detergent tablets. The dispensing of the tablets is foreseen through
a dispensing opening comprising a hinged spout. Child resistant features on the hinged
spout are also foreseen to prevent the opening of the hinged spout by children. Such
child resistant spouts are obtained by a double or coordinated action on the spout
to open the spout itself. This child resistant spout is simple to use for adults and
a good deterrent to opening for children.
[0005] Nevertheless, it has been found that by applying a sufficient force and by performing
a different opening movement, instead of the recommended actions, it is possible to
open the child resistant spout. For example, it has been found that by applying a
twisting force on some spouts, the spouts can be opened without performing the double
or coordinated actions. This twisting force may be applied by some children by trial
and error succeeding eventually to open the spout.
[0006] It is therefore an object of the present invention to provide a hinged spout for
dispensing tablets providing an improved child resistance against the opening of the
spout.
Summary of the Invention
[0007] The present invention provides a package for containing tablets. The package comprises
a dispensing opening. The dispensing opening further comprises a hinged spout for
dispensing the tablets, whereby the hinged spout provides a child resistant closure
to the dispensing opening. A hinge connects the hinged spout with the dispensing opening.
The package further comprises a rib engaging a corresponding groove when the hinged
spout is in its closed position. The engagement between the rib and the corresponding
groove is achieved between the hinged spout and the part of the package immediately
surrounding the dispensing opening opposite the hinge of the hinged spout.

Detailed Description of the Invention
[0014] Figure 1a shows a package (10) according to the present invention. The package comprises
a hollow body (11) and a dispensing opening (12). The hollow body preferably comprises
a top wall (14), a bottom wall (15) opposed to the top wall and a surrounding wall
(16) surrounding the hollow body and connected to the top and the bottom wall. The
bottom wall is the part of the package upon which the package stands in its upright
position. Preferably, the external shape of the hollow body may be substantially rectangular.
Preferably, when the package stands in its upright position, the dispensing opening
is located on the upper portion of the surrounding wall, as shown in Figure 1a, or
on the top wall.
[0015] Preferably, the inside of the hollow body (11) is filled with tablets. In the following
any form of non particulate solids such as bars or tablets or briquettes will be encompassed
by the term "tablet" (1). Pharmaceuticals in tablet form are, for example, tablets
according to the present invention. Preferably, the tablet is made of a detergent
composition, specifically a detergent composition for washing of laundry or dishes.
The tablet may have any shape or dimension. Preferably, the solid, non particulate
tablet is symmetrical to ensure the uniform dissolution of the tablet in the wash
liquor or in other specific environments.
[0016] According to the present invention the detergent tablet (1) may comprise any ingredients
known in the art. Such ingredients may include surfactants, suds suppressers, beaches,
chelants, builders, enzymes, fillers and perfumes.
[0017] Preferably, the detergent composition of the tablet (1) is prepared in its granular
or particulate form and then formed into tablets of the desired shape and size by
any one of the methods known in the art. Suitable methods include compression, extrusion
and casting. The detergent composition may be homogeneously distributed throughout
the tablet or may comprise distinct layers of certain detergent ingredients. Preferably,
the shape of the detergent tablet is cylindrical, as shown, for example, in Figure
7a. In this case the dimensions of the detergent tablet are defined by the diameter
(d) and by the height (h). Usually, detergent tablets have a cylindrical shape with
the diameter being greater than the height of the tablet. Another possible shape of
the tablet is rectangular, as shown, for example in Figure 7b. In this case the dimensions
of this detergent tablet are defined by the length (L), by the width (w) and by the
height (h). Usually, in a rectangular tablet the length is the greatest dimension
and the width is equal to the height.
[0018] As a preferred option, the top wall (14) of the hollow body (11) comprises a refilling
opening. The refilling opening allows to refill the hollow body with new tablets (1)
once the package is emptied. Therefore, the dimension of the refilling opening corresponds
at least to the dimension of a tablet. As a preferred option, the refilling opening
is closed by a closure, more preferably by a child resistant closure. The child resistant
closure is adapted to prevent the removal of the tablet (1) through the refilling
opening by infants and children. In particular, as used herein, the wording "child
resistant closure" refers to any mechanism whereby access to the tablet is reduced
so that the tablet cannot be readily removed, especially by infants and children.
An example of a child resistant closure is a closure on which the user has to apply
a double or co-ordinated action on the closure to open the closure. For example, such
child resistant closures are press-and-turn or press-and-pull closures known by the
person skilled in the art.
[0019] The dispensing opening (12) is dimensioned in such a manner to enable the passage
of at least one tablet. Preferably, the dispensing opening is made of a rectangular
cut through the thickness of the surrounding wall (16) and/or top wall (14). For a
cylindrical tablet as described above, the dispensing opening is made preferably of
a cut having the length equal or greater than the diameter (d) and the width equal
or greater than the height (h) of a cylindrical tablet. For a rectangular tablet as
described above, the dispensing opening is made preferably of a cut. This cut has
the length equal or greater than the length (L) of a rectangular tablet, whereby the
width of this cut is equal or greater than the width (w) or height (h) of a rectangular
tablet. Most preferably, the dispensing opening is located on that part of the surrounding
wall having the smallest dimension, as shown in Figure 1a.
[0020] As a preferred option, the hollow body (11) of the package comprises a funnel around
the dispensing opening (12) to convey the tablets from the interior of the hollow
body towards the dispensing opening. This funnel should be made in such a manner that
the tablets are prevented to jam in the interior of the hollow body and in front of
the dispensing opening blocking the exit through the dispensing opening for other
tablets. This funnel may be, for example, conically shaped located in the interior
of the hollow body having the smallest dimension in front of the dispensing opening.
This funnel directs the tablets towards the dispensing opening in such a manner that
the tablets pass through the dispensing opening without blocking each other.
[0021] As another preferred option, the internal dimension of the hollow body (11) is such
that the tablets are orderly spaced one to each other. This also prevents that the
tablets jam in the interior of the hollow body and in front of the dispensing opening
blocking the exit through the dispensing opening for other tablets. This is achieved
by limiting the internal width (Fig. 3a, W
i) of the hollow body to a width which is smaller than the largest dimension of the
tablets. The "internal width" is hereinafter defined to be shortest distance between
adjacent walls in a direction along the drawn line (5) in Figure 3a. Figure 3a is
a cross sectional cut of a package according to the present invention on a plane parallel
to the bottom wall (15) of the package.
[0022] For example, when the tablet (1) has a cylindrical-type of shape as described above,
such a detergent tablet may only enter into the hollow body (11), if the tablet is
placed onto the bottom wall (15) standing on the surface having the smallest dimension,
i.e. its height (Fig. 7a, h). This means that the tablet can never lay on the surface
defining the diameter (d) of the tablet. Consequently, the tablets are ordered in
a row, as shown, for example, in Figure 3a. As hereinafter referred to, a "row of
tablets" is meant to be a row of tablets standing upon the bottom wall (15) or upon
another row of tablets whereby each tablet stands on the part of the tablet having
the smallest dimension, i.e. on the height (h) for the tablets defined before. Therefore,
the internal width is a distance perpendicular to the row.
[0023] It has been found that this way of positioning the tablets (1) reduces the friction
forces acting onto the tablets. Reducing the friction forces permits an easy dispensing
of tablets from the package avoiding that tablets block each other from exiting the
package. This is particularly important when the tablets are big and/or heavy where
the friction forces between the tablets are substantially high. For example, friction
forces between tablets may influence the dispensing of the tablets from the package
when the largest dimension of the tablet is greater than 1 cm and/or the weight of
the tablet is greater than 10 g. The roughness of the external surfaces of the tablets
also contributes to increase the friction forces between the tablets.
[0024] The friction forces between the tablets (1) are reduced in the package according
to this embodiment of the present invention. Indeed, only the smallest surface of
a tablet interacts with other tablets and/or with the end wall. Furthermore, when
the tablet is cylindrically shaped as described before, the tablet is able to roll
towards the dispensing opening which further reduces the friction. Therefore, the
tablet in the hollow body cannot block other tablets contained in the hollow body
from exiting through the dispensing opening.
[0025] In a preferred embodiment of the present invention the tablets (1) are orderly held
in the hollow body (11) in one row within its internal width (W
i). Other single rows may be placed on top of the lowest row starting from the row
standing on the bottom wall (15) until the hollow body is filled up to the top wall
(14). As another possibility, the hollow body may be such to contain more than one
row of tablets parallel to each other within the internal width (W
i), when the diameter (d) or the length of the tablet is greater than twice the height
of the tablet. Indeed, the hollow body may contain, for example, two parallel rows
of tablets within the internal width (W
i), as shown in Figure 3a. Also in this case, the diameter (d) or the length of a tablet
is greater than the width (W
i) of the hollow body, the width (W
i) being now equal or slightly greater than twice the height of a tablet. Again, these
double rows of tablets are placed each over another filling up the hollow body to
the top wall (14) starting from the bottom wall (15). It has been found that when
the tablets are placed inside the hollow body, the tablets automatically get ordered
in these single or double rows. Indeed, the tablets are forced into one of the rows
by the weight of the tablets of the above rows. The same applies for more than two
parallel rows of tablets when the diameter of the tablet (d) is greater than n-times
the height (h) of the tablet, n being greater or equal to 2.
[0026] As a further preferred option, when two or more rows of tablets (1) are to be placed
inside the hollow body, the hollow body comprises preferably at least one divider
(30), as shown in Figure 3b. Figure 3b is again a cross sectional cut along a plane
parallel to the bottom wall (15). The divider is perpendicular to the direction drawn
by line (31) in Figure 3b. The divider starts from the bottom wall (15) up to the
top wall (14). The hollow body may comprise more than one divider to contain several
rows of tablets. The width (w) between the surrounding wall (16) and the divider or
between each divider is smaller than the largest dimension, i.e. the diameter or the
length, of the tablet. Consequently, the dividers divide the parallel rows of tablets
from each other. In this manner, the friction between parallel rows is reduced to
achieve an easy and readily dispensing of the tablets. When the hollow body comprises
the dividers (30), the package may preferably comprise one dispensing opening (12)
enabling the tablets of each divided row to exit the package.
[0027] The dispensing opening (12) further comprises a hinged spout (20). In a preferred
embodiment, as shown in Figure 4a, the hinged spout comprises a supporting wall (21).
One end edge (26) of the supporting wall is connected to the package, specifically
at the dispensing opening. The connection between the end edge (26) of the hinged
spout and the dispensing opening is a hinge. The other edges of the supporting wall,
i.e. the side edges (28) and (29) and end edge (27), are free from any attachments
to the package. The hinged spout (20) is attached to the dispensing opening (12) in
such a manner that a tablet exiting the dispensing opening is received by the hinged
spout when the hinged spout is in its open position. For example, when the dispensing
opening is located on the surrounding wall (16), the supporting wall (21) is located
under the dispensing opening when the package stands in its upright position and the
hinged spout is in its open position, as shown in Figure 1a.
[0028] Preferably, the hinged spout further comprises two side walls (22), more preferably
two side walls and an end wall (25). The side walls and the end wall, if present,
are all located on one side of the supporting wall. The two side walls are preferably
located along the side edges (28) and (29) of the supporting wall. The side walls
are opposed to each other along the side edges (28) and (29). The side walls may remain
at the same distance from each other or the distance between the side walls may become
narrower or broader towards the end wall.
[0029] The end wall, if present, is located opposed to the dispensing opening and is placed
parallel to the end edge (27) or the width (W
s) of the supporting wall, i.e. the end wall is located at least partially along the
width (W
s) of the supporting wall. For example, the end wall may be a bar, whereby each end
of the bar is connected to a side wall (22). Preferably, the end wall is connected
to the supporting wall and located along the end edge (27). The end wall and the side
walls are inclined walls with respect to the supporting wall, and the end wall may
also be inclined to the side walls. In a preferred embodiment of the hinged spout,
the end wall and the side walls are perpendicular to each other and to the supporting
wall. In another preferred embodiment of the hinged spout, the end wall and the side
walls are connected to each other, therefore leaving no interspaces between the end
wall and the adjacent side walls.
[0030] The shape and the dimensions of the hinged spout (20) are such to enable the receiving
of a tablet (1) contained in the package. For example, when the package contains cylindrical
tablets, as described above, and the dispensing opening (12) has a rectangular shape
the hinged spout has preferably following dimensions shown in Figures 4a and 4b. The
width (W
s) of the supporting wall (21) is preferably slightly greater than the height (h) of
the tablet. This allows the tablet to stand on the surface of the tablet having the
smallest dimension, i.e. its height (Fig. 7a, h). Consequently, the tablet is facilitated
to exit the dispensing opening by rolling onto the supporting wall. Preferably, the
width (W
s) of the supporting wall is between about 1 times the height (h) of the tablet and
1.5 times the height (h) of the tablet, more preferably about 1.2 times the height
(h) of the tablet.
[0031] The dimensions of the preferred embodiment of the hinged spout (20) further comprising
the end wall (25) and the side walls (22) are such that a tablet is held onto the
hinged spout. The end (25) and the side walls (22) of the hinged spout prevents that
the tablet (1) exiting from the dispensing opening (12) falls from the hinged spout.
Furthermore, until the tablet remains on the hinged spout, the exit of other tablets
through the dispensing opening may be prevented. Indeed, the dimensions of the hinged
spout may allow only one tablet to stay on the hinged spout. Consequently, other tablets
are prevented to exit the dispensing opening by the tablet already staying on the
hinged spout. Therefore, the hinged spout enables a one-by-one dispensing of the tablets
through the dispensing opening. Furthermore, the additional end wall prevents that
tablets fall uncontrolled from the dispensing opening. The user has only to grasp
the tablet which is held on the hinged spout. This avoids messiness in the dispensing
of tablets.
[0032] The height (H
s) and lengths (L
s,2) and (L
s,3) of the side walls (22) and the end wall (25) respectively, if present, should provide
a sufficient barrier which impedes the falling of the tablet from the supporting wall
of the hinged spout. Consequently, the tablet is held onto the hinged spout with the
help of the end and side walls. On the contrary, the height (H
s) of the end and side walls should not impede an easy grasping of the tablet by a
user. The height is the minimum distance between the supporting wall and the upper
edge of the end wall or side walls. For, example, when the end wall is a bar as described
above, the height is the distance between the supporting wall and the upper edge of
the bar. The length, however, is measured parallel to the end edge (27) or side edges
(28) and (29), i.e. perpendicular to the height.
[0033] Preferably, the height (Fig. 4b, H
s) of the side walls and the end wall is between about 0.2 times the diameter (d) of
the tablet and about 1 times the diameter (d) of the tablet. Most preferably, the
height (H
s) of the side walls and the end wall is about 0.5 times the diameter (d) of the tablet.
As a preferred option, the height (H
s) of the end wall is equal to the height of the side walls. As another preferred option,
the height (H
s) of the side walls is not constant. For example, the height (H
s) of the side walls is curved increasing the height (H
s), as shown for example in Figure 4b. In this case, the maximum height (H
s, max) is still within the range described before. The side walls may curve only at one
end or at both ends of the side walls. The curvature may also be such to decrease
the height (H
s) of the side walls, but still within the range of the height (H
s) as described before. The length (L
s,2) of the side walls is preferably between about 0.5 times to 1 times the length (L
s,1) of the supporting wall (21). The length (L
s,3) of the end wall is preferably between 0.5 times to 1 times the width (W
s) of the supporting wall (21).
[0034] The distance between the end edge (26) and the end wall (25), if present, is preferably
such that substantially a complete tablet has a sufficient space on the hinged spout.
In this arrangement the tablet can easily exit from the dispensing opening (12) and
can be easily grasped by the user. Preferably, the distance between the end edge (26)
and the end wall is between about 0.8 times the diameter (d) of the tablet and about
2 times the diameter (d) of the tablet, more preferably between about 1 times the
diameter (d) of the tablet and about 1.6 times the diameter (d) of the tablet.
[0035] The hinged spout (20) closes the dispensing opening (12). This may be achieved, for
example, when the hinged spout pivots around the end edge (26) hingedly connected
to the package. The hinged spout is therefore closed by pushing the hinged spout into
the dispensing opening (12), the hingedly connected end edge (26) acting as a hinge.
The hinged spout is retained in the dispensing opening through a closing mechanism
between the hinged spout and the lip of the dispensing opening. The closing mechanism
keeps the hinged spout inside the dispensing opening in a closed position. An example
of a closing mechanism is a snapping engagement between the hinged spout and the lip
of the dispensing opening.
[0036] The hinged spout (20) according to the present invention closes the dispensing opening
(12) in a child resistant manner. The child resistant means of the hinged spout is
adapted to prevent the removal of the tablet (1) through the dispensing opening by
infants and children. In particular, as used herein, the wording "child resistant"
refers to any mechanism whereby access to the tablet is reduced so that the tablet
cannot be readily removed, especially by infants and children. An example of a child
resistant means is a closure on which the user has to apply a double or coordinated
action on the closure to open the closure.
[0037] For example, such a child resistant means is shown in Figures 1a, 1b, 2a and 2b.
The hinged spout (20) comprises a child resistant means located between the end wall
(25) and the top wall (14). Preferably, the child resistant means comprises a hook
(31) and holding means (32). The holding means engages with the hook in such a manner
that the hook is retained by the holding means until the hook is disengaged or unhooked
from the holding means. Preferably, the holding means (32), located on the end wall
(25) of the hinged spout, comprise a slot (33) in which the hook (31), located on
the top wall (14), at least partially snaps into. The location of the hook and the
holding means may also be reversed to each other, as shown in Figure 2a, i.e. the
hook on the end wall and the holding means on the top wall. To disengage the hook
from the slot, the hook is pressed until the hook exits from the slot. Furthermore,
to completely open the hinged spout, the hinged spout has to disengage from the closing
mechanism described before between the hinged spout (20) and the surrounding wall
(16) of the package (10).
[0038] The holding means (32) may alternatively comprise a counter-hook (34), as shown in
Figure 2b. The hook and counter-hook are located in opposition to each other, whereby
the hook or counter-hook may be located on the end wall or the top wall. Preferably,
the hook or the counter-hook may bent in such a manner that it conform to the rest
of the outermost surface of the end wall or the top wall, as shown in Figure 2b. Indeed,
the hook (31) of Figure 2b located on the top wall (14) comprises a bent wall (35)
uniting the hook to the outermost surface of the top wall. By pressing on the top
wall, the hook can be disengaged from the counter-hook (34). This child resistant
means can be foreseen also for other types of closures, like screw-on or snap-on caps.
The hook/holding means combination is only an example of a child resistant means according
to the present invention. Other possible child resistant means suitable for the package
according to the present invention, like where the spout has to be first pressed on
the side wall of the spout and then pulled, are described in the co-pending European
patent application No. 95308468.8.
[0039] To further improve the child resistance against the opening of the hinged spout (20)
according to the present invention, the package (10) further comprises a rib (41)
engaging a corresponding groove (42) when the hinged spout (20) is in its closed position.
The engagement between the rib and the corresponding groove is achieved between the
hinged spout and the part of the package immediately surrounding the dispensing opening
(12) opposite the hinge of the hinged spout. The engagement of the rib and the groove
may simply be a fitting of the rib into the groove without further engaging means.
As a preferred option, to further improve the child resistance, the rib may engage
into the groove with a clipping mechanism into the groove. The positioning of the
rib and the groove is such that the opening of the hinged spout is prevented when
the spout is twisted. Indeed, the rib engaged in the groove prevents that the hinged
spout is opened in another direction different from the pivoting direction of the
hinge of the hinged spout.
[0040] Preferably, the free end edge (27) of the hinged spout comprises the rib (41) engaging
into the groove (42) located on the surrounding wall (16) when the hinged spout (20)
is in its closed position. Alternatively, the positioning of the rib and the groove
may be interchanged with respect to the previous configuration. When the hinged spout
comprises the child resistant means given by the hook/holding means arrangement, the
engagement between the rib and the groove is preferably obtained at least on one side
of the hook/holding means engagement. More preferably, the hinged spout comprises
two ribs or grooves on opposite sides with respect to the hook/holding means engagement.
In this manner, the resistance to opening by children with a twisting movement is
further improved.
[0041] The groove (42) is at least a partial cut through the thickness of the package or
of the hinged spout (20). The dimensions of the groove (42) correspond to the dimensions
of the rib (41) so that the rib goes completely into the groove. The groove may be
located on the outermost or innermost surface of the package or on the upper or lower
surface of the hinged spout. More than one groove with corresponding rib can be foreseen
on the package according to the present invention. For example, the package may comprise
succeeding ribs engaging into corresponding succeeding grooves.
[0042] As a preferred option, the hinged spout (20) further comprises a stopping notch (1a,
45). The stopping notch stops the opening of the hinged spout to a partial opening
position of the hinged spout, as show in Figure 1a. Several stopping notches can be
foreseen, each of the stopping notches determining a different partial opening position
of the hinged spout. Preferably, in a first opening position only one tablet is able
to exit onto the hinged spout. This means that specifically this stopping notch ensures
that tablets are dispensed one by one from the container. This is due to the inclination
of the supporting wall with respect to the full opening of the hinged spout. Indeed,
the higher inclination limits the available space for the tablets. It has been found
that the one by one dispensing of tablets can be made independent, with the help of
the stopping notch, from the length of the supporting wall of the hinged spout. Indeed,
it has been found that the length of the supporting wall may be greater than 1 time
the diameter (d) of the tablet, and still only one tablet is able to exit on the hinged
spout when the stopping notch stops the opening of the hinged spout to a partial opening
position. When the hinged spout is further opened passing over the stopping notch,
the hinged spout may be stopped by another stopping notch or, finally, the hinged
spout is completely opened.
[0043] The stopping notch (45) may be located in any place of the hinged spout (20) such
that the hinged spout interacts with the opening (12) and stops the opening of the
hinged spout to a partial opening position. Preferably, the stopping notch is positioned
on the outermost surface of at least one of the side wall (22) of the hinged spout
(20). Specifically, the stopping notch is an extension protruding away from the outermost
surface of at least one side wall. As a preferred option, both side walls (22) may
comprise each a stopping notch. As another preferred option, several stopping notches
may be provided on each of the side walls. The position of the stopping notch may
also be such that the stopping notch interacts with the upper or lower portion of
the opening when the package stands in its upright position.
[0044] When the package comprises divided rows of tablets, as described before with or without
the dividers (30), the package may preferably comprise a hinged spout (20) for each
divided row of tablets. More preferably, the hinged spouts are attached to the neighbouring
hinged spout corresponding to another row of tablets forming a single hinged spout
capable to dispense a multiple of tablets at the same time, as shown in Figure 1a.
As an option, the opening comprises a retaining barrier (46), as shown in Figure 1a.
As described before, the stopping notch (45) on the hinged spout stops the hinged
spout to a partial opening position. The partial opening position of the hinged spout
allows only one tablet at a time to exit onto the hinged spout from one row. At the
same time, the retaining barrier (46) on the opening prevents that another tablet
of another row exits on the hinged spout. The retaining barrier may, for example,
be a flap extending from the top edge of the opening (12) downwards, as shown in Figure
1a. Consequently, the tablets of only one row are allowed to exit onto the hinged
spout.
[0045] When the tablets of one row are finished, the hinged spout (20) may be opened further
until the hinged spout is again stopped by another stopping notch (45) or the hinged
spout is completely opened. In one of these opening positions, the hinged spout is
sufficiently opened that the tablets of the other row are able to pass under the retaining
barrier (46). The retaining barrier may also be a flap (47) hinged on a divider in
the opening region, as shown in Figures 5a and 5b. The hinged flap (47) extending
into the opening of the tablets of a row prevents the exit of these tablets (Fig.
5a). Once one row is emptied, the hinged flap (47) is turned to the empty row, as
illustrated in Figure 5b enabling the tablets of the other row to exit on the hinged
spout. Another possibility is a removable cover (48) which can be applied in the opening
region of one row of tablets, as shown in Figures 6a and 6b. The removable cover may
be anything which impedes the exit of tablets through the opening. For example, a
removable cross, as illustrated in Figure 6a, or a adhesive sticker, as illustrated
in Figure 6b may be used as a removable cover.
[0046] Preferably, the package (10) and the hinged spout are made of thermoplastic material.
Such thermoplastic materials have been extensively described in the art and include
vinyl chloride based resins, polymers and co-polymers derived from olefins, acrylic
polymers and co-polymers, polyethylene, polypropylene, polystyrene, polyethylene terephthalate,
polyethylene terephthalate glycol, or mixtures thereof. The container can be made
of single or multi-layer extrusion of such materials. It can also comprise recycled
thermoplastic materials. A preferred thermoplastic material used herein is polyethylene.
Preferably the package is made of low cost thermoplastic material such as polypropylene
