[0001] This invention relates to a toothpick dispenser in accordance with the introduction
to the main claim.
[0002] Various types of toothpick dispenser are known. For example dispensers are known
comprising a casing having a part provided with a hole which allows a toothpick to
emerge from the hollow interior of the casing following suitable manipulation thereof.
A dispenser is also known comprising a casing containing elastic parts which, on pressing
a suitable pushbutton projecting from the casing, expel the toothpick from the hollow
interior.
[0003] These known arrangements have various drawbacks. For example, they are of complicated
construction and therefore of high cost. Alternatively, they do not provide easy release
of the toothpick, which can become jammed within the dispenser. In addition, known
dispensers have the drawback of not preventing an already used toothpick being reinserted
into them. There is therefore a serious question of hygiene for a person using toothpicks
for example in a bar, restaurant, canteen, etc.
[0004] An object of the invention is to provide a toothpick dispenser which obviates the
drawbacks of the aforesaid known dispensers.
[0005] A further particular object of the invention is to provide a dispenser of the stated
type which is of simple construction, is of low cost and is hygienically safer than
known dispensers in that an already used toothpick cannot be reinserted into it.
[0006] These and further objects which will be apparent to the expert of the art are attained
by a dispenser in accordance with the accompanying claims.
[0007] The present invention will be more apparent from the accompanying drawing, which
is provided by way of non-limiting example and in which:
Figure 1 is an exploded view of the dispenser according to the invention;
Figure 2 is a view from above of the dispenser of Figure 1;
Figure 3 is a partial perspective view of a modification of the dispenser of Figure
1;
Figure 4 is a section on the line 4-4 of Figure 3;
Figure 5 is a section on the line 5-5 of Figure 3;
Figure 6 is a section similar to that of Figure 5, taken through a different embodiment
of the invention.
[0008] With reference to said figures, a dispenser for toothpicks S is indicated overall
by 1 and comprises a casing 2 having two portions 3 and 4 which are engaged with each
other (preferably by snap-engagement) and are movable relative to each other along
a common intermediate plane P (see Figure 5). The two portions 3 and 4 move with translational
movement relative to each other along said plane. The portion 4 is longer than the
portion 3 in the direction of mutual movement L of the two portions, these latter
being of tray shape (ie each having a cavity 3C and 4C respectively) so as to define
a hollow interior 6 within the casing 2 in which the toothpicks S are placed.
[0009] At one end 4A, the portion 4 comprises a flange 7 provided with a raised projection
or shoulder 8 arranged to define a limit stop for the movement of the portion 3 relative
to the portion 4. This latter has another flanged end 4B in which there is an elongate
recess 10 able to receive the toothpick to enable it to be removed from the hollow
interior 6.
[0010] The portion 3 has one end 3A facing the recess 10 and able to move relative to and
above it so as to reach the free extremity 12 of the flanged end 4B.
[0011] The end 3B of the portion 3 has a tapered free extremity 13 with its inner part 13a
smoothly blending into the inner wall 14 of the end 3A.
[0012] The portion 3 laterally comprises flanges 17 and 18 arranged to cooperate with substantially
L-shaped guide elements 19 and 20 projecting upwards from side walls 21 of the portion
4.
[0013] Each element 19 or 20 has its upper part tapering on that side 19A or 20A facing
the interior of the portion 4. This is to allow snap-engagement between the portions
3 and 4 by forcing the flanges 17, 19 down onto the elements 19 and 20, by which the
sides 19A and 20A thereof are made to move elastically away from the interior of the
portion 4 to allow the portion 3 to be inserted so that it lies on the opposing side
walls 21 of the portion 4. Between each pair of elements 19 and 20 there is provided
a member 11 arranged to cooperate with the flanges 17 and 18 of the portion 3 so as
to act as a stop for its movement in particular towards the extremity 12 of the portion
4. On fixing the portions 3 and 4 together, this member becomes positioned in correspondence
with an aperture 11A provided between the flanges 17 and 18 of the portion 3.
[0014] Said L-shaped (or hook-shaped) elements maintain the portion 3 associated with the
portion 4 while at the same time allowing these portions to move relative to each
other. This movement is, relatively speaking, a movement of translation of the portion
3 on the portion 4, said portion 3 being able to assume two working positions relative
to the portion 4. In a first position (for example shown by full lines in Figure 5)
it frees the recess 10 and rests on a flat part 26 of a separating baffle 27 provided
between the recess 10 and the cavity 4C of the portion 4. In this first position,
the portion 3 has that end 28 distant from the extremity 13 resting on the flange
7. In the second position, the extremity 13 lies in correspondence with the extremity
12 of the portion 4 so as to provide communication between the recess 10 and the cavity
3C of the portion 3 (and hence the hollow interior 6 of the casing 2 of the dispenser
1). As described hereinafter, this enables a toothpick to pass from the hollow interior
6 to the recess 10 for its removal from the dispenser 1.
[0015] It will now be assumed that the aforedescribed dispenser is to be used to remove
a toothpick therefrom. For this purpose its casing 2 is firstly arranged in the position
shown in the figures. The portion 3 is then moved into its second working position
(described heretofore) by sliding it relative to the portion 4 along the guides defined
by the hook-shaped elements 19 and 20. The casing 2 is then rotated through 180° so
that the portion 3, which lies above the portion 4 in the figures, is brought below
this latter. Said casing is then lightly shaken to cause a toothpick to pass from
the hollow interior 6 into the recess 10. The casing 2 is again rotated through 180°
(to return to the situation represented in the figures) so that the portion 3 is returned
to its first working position (against the stop defined by the projection or shoulder
8). The recess 10 in which a toothpick has remained "trapped" is hence freed, and
the toothpick can be removed from the dispenser.
[0016] To prevent a used toothpick being reinserted into the casing 2 there is provided
in the recess 10 a projection 33 which maintains the toothpick slightly raised within
this recess. In this manner, although it is possible to remove the toothpick from
the dispenser, it is not possible to reinsert it into it. In this respect, during
the depositing of the toothpick S in the recess 10 (as heretofore described), the
return of the portion 3 to its first working position (as described) is made possible
both by the elasticity of the toothpick S and by the shape of the part 13A (smoothly
blending) of the extremity 13 of the end 3A. Consequently the "expulsion" of the toothpick
S from the hollow interior 6 and its deposition in the recess 10 so that it can be
gripped by the user takes place as described independently of the presence of the
projection 33.
[0017] It is not however possible to reinsert the toothpick S into the hollow interior 6.
In this respect, when placed in the recess 10 it assumes a raised position (as shown
in Figure 4). If an attempt is now made to move the portion 3 into its second working
position, its extremity 13 presses against the toothpick S, and as that part thereof
facing the recess 10 is in the form of a sharp edge (formed by the extremity 13 and
the outer wall 14B of the end 3A), it is unable to distort the toothpick so as to
be able to pass beyond it and reach the extremity 12 of the end 4A. Consequently it
is very difficult to reinsert the toothpick into the casing 2 of the dispenser 1.
[0018] A further arrangement for preventing the reinsertion of the toothpick S into the
casing 2 after its extraction is shown in Figure 6 in which, as an alternative to
the projection 33, there is provided within the recess 10 a rocker 35 comprising arms
36 and 37 and hinged at 38 to the baffle 27 (which for the rocker comprises a seat
39 providing communication between the recess 10 and the hollow interior 6). This
rocker can assume two working positions (shown in Figure 6 by dashed lines and full
lines respectively) corresponding to the two aforesaid positions of the portion 3.
[0019] During the use of the dispenser, passage of the portion 3 from its first to its second
working position causes the rocker to rotate about the hinge 38. The return of said
portion to its first position causes further rotation (opposite to that already described)
of the rocker by virtue of the cooperation between its arm 37 and the end 3A of the
portion 3. This rotation causes the arm 36 to rise within the recess 10, this also
causing the toothpick S to rise therein and facilitate its gripping. Reinsertion of
the toothpick into the casing 2 is made very difficult by the rocker 35 which is in
its first working position (shown dashed in Figure 6). This position cannot be changed
(for example by trying to force the rocker into its second working position) because
of the cooperation between its arm 37 and the end 3A of the portion 3.
[0020] As the dispenser 1 is preferably constructed of self-lubricating plastics material,
all the movements of its parts are facilitated and without seizure.
[0021] One particular embodiment has been described. Other embodiments are however possible
(such as one in which the casing 2 is in the form of a cylinder provided with two
semicylindrical or cylindrical sector portions of different surface areas, movable
about a common axis), while remaining within the scope of the present invention.
