[0001] The present invention relates to a dispenser for coarsely granular confectioneries,
also including dried fruit such as abricots as well as dragée by way of example ,
i.e. for dispensing granulates preferably within the size range 2 mm to 5 cm, the
dispenser having a supply container and a sluice system that can be activated from
the outside for dispensing the granulate from the container to a dispenser opening.
[0002] The invention is especially intended for use in self-service stores where the customers
can help themselves to required quantities of the goods in question, such dispensers
being arranged e.g. in a battery of dispensers containing different granulate goods
which at a standard price can be collected in e.g. a bag, which, upon completion of
its filling, can be weighed and price tagged.
[0003] A primitive form of dispensers are made up of open containers with associated spoons
for taking out the products. Such dispensers do not consider the most elementary hygienic
demands, 1owever, and are already for this reason not permissible in self-service
stores. A variety of closed dispensers for handing out special products like peanuts
and confectionery balls have been developed, but with these it is normally a question
of dispensing a quantity by volume and not a large or small quantity graduated in
accordance with the customer's requirement.
[0004] For powders dispensers consisting of a contalner with a bottom outlet are known,
underneath which a horizontally dis placable sluice frame is placed. This frame can
slide along a fixed bottom plate such that in an inserted mode it can be filled with
material from the bottom outlet and thereafter when being pulled or pushed from the
receiving area out over an open dispensing area, can carry along the actual portion
contained in the frame, whereby the portion is brought to fall down for delivery from
the dispenser. At its rear end the frame has a rearwardly projecting top plate which
prevents the falling down of material from the container when the frame is moved forwardly.
Admittedly the material is hereby dispensed in portions, but by manual movements of
the sliding frame it is possible to limit its displacement more or less, thus also
allowing the taking out of desired partial portions. This principle of dispensing
is advantageous in several ways, but it has been ascertained that it is not well suited
for the dispensing of coarsely granular products as here considered, since noticable
squeezing tendelcies occur, particularly not when a variable dispensing is desired.
[0005] In connection with the invention it has been found, surprisingly, that a dispensing
principle well suited for this purpose can be achieved by a rather small, but in fact
significant modification of the above powder dispensing principle, viz. by arranging
the bottom area of the container to be upwardly inclined as seen in the moving direction
of the sliding frame towards its open position. It has been found and will be explained
in further detail below - that the gravity contributes to solving those problems that
have otherwise been encountered when using the "horizontal" guiding principle for
the sliding frame and that the construction itself will need no alteration on the
principal level, obviously apart from size adjustments as far as required.
[0006] It has even been found that a dispenser dimensioned for handling granular products
as big as 3-4 cm, i.e. where the sliding frame must be correspondingly high, may well
be used for dragées of only 3-4 mm, whereby in practice one only apparatus model is
needed for practically all relevant types of articles, which is a great advantage
as far as the production of the dispensers is concerned. On the face if it it does
not sound appropriate to have e.g. dragées dispensed from an identical type of apparatus
which is also used for e.g. dried abricots, but here it must be considered that it
is not a matter of fixed volume dosages but of a dispensing controlled by the user,
who can stop it when his demand has been fulfilled. The drawer chamber in the sliding
frame may be quite large without the user in any way be induced to overdose when the
apparatus contains a granulate of a small particle size. It is also important here
that the bottom area is slanting as mentioned, as a "high" layer of small particles
will overflow the delivery edge in a better controlled manner than when it be a horizontal
layer.
[0007] The invention which is further defined in the claims, is explained in more detail
in the following with reference to the drawing, in which:-
Fig. 1 is a perspective view of a dispenser according to the invention,
Fig. 2 is a lateral sectional view therof, and
Fig. 3 is an enlarged view of a partial area thereof.
[0008] In the drawing is shown a dispenser having a container 2, which is obliquely upstanding
from a likewise inclined bottom area, though the container 2 could well extend vertically
upwardly from the inclined bottom area. This area comprises a foremost, upper bottom
plate 4, which projects rearwardly underneath the container 2, approximately halfway
of the depth dimension thereof, and a lower bottom plate 6, which, spaced underneath
the upper plate 4, projects from the rear to a front edge area 8 in front of the rear
edge of the upper plate 4. From this area the plate 6 continuous in a funnel portion
10, the front wall of which is constituted by a downwardly directed prolongation of
the front wall, designated 12, of the container 2.
[0009] Between the planes defined by the plates 4 and 6 is mounted a slide frame element
14, which is slidably supported on the bottom plate 6 and consists of a foremost frame
portion having upright rear, front and side walls, 16, 18 and 20, respectively, and
a rear, lying plate portion designated 22, which projects rearwardly from the upper
edge of the rear side wall 16, flush with the upper edges of the side walls 20. The
rear container wall, designated 24, has its lower end or edge located just above the
top side plane of the plate portion 22. Both the container 2 and the bottom area thereof
is confined between opposed, parallel side walls 26.
[0010] The frame element 14 is connected with a forwardly projecting drawbar 28, which projects
through a hole in the front wall of the container 2 and is provided with an outer
pulling handle 30. The rear wall 16 of the frame element is provided with a hook 32
serving to hold one end of a rubber string 34, the other end of which is secured to
a hook portion 36 connected with the bottom plate 6. Thus, by pulling out the handle
3C, the frame element 14 will be forwardly displaceable against the action of the
rubber string 34, whereby the frame element is moved out over the funnel portion 10.
By this movement the rear, lying plate portion 22 of the frame element will be moved
into a position underneath the lower outlet opening 38 of the container 2 so as to
close this outlet until the frame element is returned into its initial position.
[0011] The basic concept of this outsluicing system is not really novel, but it is novel
and entirely decisive for the invention that the bottom area of the dispenser container
is inclined upwardly and forwardly in the direction of the drawing out of the frame
element 14; granular products cannot be dispensed in a well controlled manner unless
the bottom portion assumes an angular position of at least some 10° with the horizontal
plane, and a preferred angle is some 30° or at least somewhere between 10° and 50°.
[0012] The lower edges of the side walls 26 of the container 2 are shaped or cut such that
the bottom portion of the dispenser will be inclined as desired when the dispenser
unit is placed on a horizontal support such as a shelf, and in the rear side of each
side wall 26 there is provided a lower notch 38, which ge with a complementary holding
portion adjustment the rear side of the shelf for holding the dispenser relative the
user's pulling out of the actuator rod 28. Preferably this rod projects rearwardly
through a hole in the front wall 18 of the frame element so as to be fixed to the
rear wall 16 of this element, this rear wall via its connection with the rearwardly
extending plate portion 22 being reinforced against being bent by the pull in the
drawbar 28. However, for the dosing out of the material it is impertinent whether
the drawbar 28 is thus traversing the space inside the frame element 14.
[0013] The upper bottom plate 4 is supported in a liftable manner for facilitating a cleaning
of the dispenser.
[0014] The foremost wall portion 18 of the frame element 14 is not strictly necessary, but
it will prevent outlets of articles by incidental impacts and shutterings, and besides
it will form a hygienic barrier between the contents of the container 2 and the article
delivery area.
[0015] In a practical embodiment of the invention the height of the sliding frame is some
35 mm, while the spacing between the top plane of the frame and the overlying plate
4 is some 10 mm, whereby jamming problems will be avoided. The plate 4 projects some
3 cm rearwardly beyond the front wall 18 of the slidable frame 14, such that the frame
14 can be filled only partially with granular material falling down from the container
2. The length of the plate 4 is 8-9 cm, which also applies to the length of the open
portion of the frame element 14. Thus, the frame element may be advanced through some
6 cm, approximately corresponding to the length of the opening 38 and of the delivery
opening in front of the frame front wall 18.
[0016] Optionally the upper bottom plate 4 can extend further upwardly inclined from its
free rear edge, whereby any remaining jamming risk will be eliminated. However, it
has been found that this risk is overcome already by the inclined positioning of the
system and by the other measures.
[0017] The inclined orientation is particularly important for making sure that the material
can be dispensed at a moderate rate during the initial displacement of the sliding
frame, when the dispenser with its relatively high sliding frame is used for a material
of small particle size, e.g. for dragées, as sought illustrated in Fig. 3.
[0018] In Fig. 2 an inclined dotted line 40 is drawn downwardly and forwardly from the rear
edge of the upper bottom plate 4, representing the front side or the angle of slide
of the material as deposited on the lower bottom 6 from the container opening 38
when the sliding frame 14 is in its rear position. This line will not reach as far
as to the delivery edge 8 or at least not much higher than that, and when the frame
is initially pulled forwardly the foremost particle as hereby eased over the edge
8 will not cause the overlying particles in the front layer to lose their support,
i.e. normally even a single particle may be dispensed in a controlled manner, this
being practically impossible if the slide is horizontally oriented. Thus the user
may dispense the articles if not one by one then at least few by few as the handle
30 is pulled, such that a well controlled amount of particles can be taken out, even
when the particles are small.
