Field of Application
[0001] The invention relates, particularly but not exclusively, to a dispenser for granular
or powdered food products, such as grated cheese and the like food products in loose
form.
[0002] The invention relates, particularly but not exclusively, to the packaging, the long-term
preservation and the dispensing of such dairy products as grated cheese, and this
description covers this field of application for convenience of illustration only.
Prior Art
[0003] Already for some years, there has been growing acceptance by the consumer public
of certain food products which, despite their perishable nature, can be bought at
the food store in an as-fresh condition by virtue of the products having been packaged
under an inert medium and/or stored at a low temperature, e.g. at +4°C.
[0004] A typical example may be that of freshly made "pasta", regarded nowadays as a product
with a medium shelf-life to be kept in the cooled counters of food stores.
[0005] Packaging techniques have been developed which represent useful contributions towards
preserving the organoleptic characteristics of food products, and which suit different
sorts of perishable products and consumption styles. For dairy products, such as e.g.
aged cheese, a packaging technique has long been in use, whereby cheese cuts are vacuum
packaged under a transparent film envelope, the film being wrapped around the product
and heat sealed in the process of drawing the vacuum. Further as relates to aged cheese,
consumers appear to welcome pre-grated cheese, which are customarily sold in pliant
bag packages.
[0006] Another way of storing grated cheese in a durable manner is to pack it into tray-type
containers of a thermoformed plastics material, which containers are closed at the
top with a sheet cover heat sealed all around the container rim. Although advantageous
on several counts, such containers are of limited serviceability for, once opened
for consumption, they cannot be re-sealed to ensure a good preservation of the product,
so that the latter has to be consumed within a comparatively short period of time.
[0007] In this context, there also exists a growing demand from consumers for containers
that can also serve as dispensers of a loose product packaged therein.
[0008] For this purpose, the prior art provides rigid containers of a generally cylindrical
shape, which mount sophisticated dispensing and re-sealing structures effective to
preserve, within limits, the organoleptic characteristics of the product and at the
same time ensure that it can be conveniently dispensed.
[0009] These dispensing containers have major limitations in their high cost, due to the
complicated construction of their dispenser part, and in their unsuitability to provide
disposable packages, a form that is looked upon favorably by both consumers and store
operators.
[0010] A cheaper alternative is disclosed in Italian Utility Model Patent No. RE95U000016,
which provides a cup-shaped container that is closed at the top with a sheet cover
heat-sealed to the cup rim, the container having an aperture at its bottom for dispensing
its contents.
[0011] The last-mentioned solution is quite inexpensive, but has failed to attract commercial
interest due to an important flaw in its design. The downward tapering shape of the
cup combines with the weight of its contents to funnel and crowd the granular particles
toward the cup bottom. Thus, the particles becomes tightly packed and cannot be dispensed
through the bottom opening any more. This effect is enhanced in the case of products
with a high moisture content, such as grated cheese.
[0012] The technical problem underlying this invention is that of providing a dispenser
for loose food products, in particular granular or powdered products such as grated
cheese, with appropriate structural and functional features to allow a long-term preservation
of the food products therein contained, as well as to facilitate dispensing in precise
amounts, thereby to overcome the drawbacks outlined with reference to the prior art.
Summary of the Invention
[0013] The principle upon which the solution proposed in the present invention is founded
is that of providing a dispenser in the form of a tray-type container having at least
one side wall formed with a discharge port that is normally closed by a tear-off label.
[0014] Based on this principle, the technical problem is solved by a dispenser as previously
indicated and defined in the characterizing part of Claims 1 foll..
[0015] The features and advantages of a dispenser according to the invention will be apparent
from the following description of an embodiment thereof, given by way of non-limitative
example with reference to the accompanying drawings.

Detailed Description
[0017] With reference to the drawing views, a dispenser of granular or powdered food products,
such as grated cheese or the like loose food products, according to this invention,
is shown at 1 in schematic form and is adapted to conserve food products durably therein.
[0018] The dispenser 1 also serves as a container for the food product, a granular type
of food product being generally shown at 10. This dispenser is also suitable for long-term
storage of the products therein in the cooled counters of food stores.
[0019] Advantageously in this invention, the dispenser 1 comprises a tray-type container
2, which is closed at the top with a sheet cover 3 of a synthetic material heat-sealed
all around the tray rim.
[0020] The container 2 is preferably made of a thermoformed synthetic plastics material
for food applications. The product 10 is contained and preserved in the dispenser
1 under an inert atmosphere, preferably nitrogen gas.
[0021] In a preferred embodiment, the container 2 is thermoformed from a multi-layer sheet
of a transparent synthetic material. More particularly, the multi-layer sheet comprises:
an outward layer of polystyrene, polyolefin, or polyester resins; an intermediate
barrier layer, e.g. ethylvinyl alcohol; and an inward layer of weldable polyesters.
[0022] The intermediate layer is substantially air-impervious and exerts an antagonist activity
towards oxygen. Thus, the intermediate layer serves an anti-ageing function that contributes
to a proper and durable product preservation.
[0023] Sheet 3 also has a multi-layered structure and includes an oxygen-antagonist intermediate
layer.
[0024] The tray-type container has a shallow elongate shape, with a length dimension L greater
than the width N, and a depth H being ¼ to ½ the length L.
[0025] Preferably, the depth H of the tray-type container is less than one-third its length
L.
[0026] Advantageously, at least one side wall 4 of the tray is formed with a discharge port
5 through which the loose granular product can flow out in use of the dispenser by
a consumer of the product. In such a way, the granular product is not crammed against
the discharge port 5 by gravity, and the flaking off and delivery of the grated cheese
is facilitated.
[0027] The port 5 is circular and has a diameter of 14 to 22 mm, preferably of 16 mm.
[0028] A label 6 is applied originally over the port 5 to keep the dispenser 1 sealed throughout
its shelf life, and is adapted to be torn off by the consumer. The label 6 also includes
a barrier layer of the same type as that provided in the structure of the container
2.
[0029] The label 6 is of a self-sticking type with an adhesive-free tab 9 providing a grip
for tearing off the label. Alternatively, the label 6 could be heat sealed.
[0030] The dispenser 1 is also provided with a stopper 11 for quick application to the port
5 to close it again after use. If desired, the stopper 11 may be perforated and include
a snap-on cap.
[0031] In a second embodiment, shown particularly in Figure 2, the dispenser 1 has a side
wall 4' set at an angle β of inclination to the container bottom 7. This dispenser
also has a flat side wall portion 4" set at a smaller angle α of inclination to the
tray bottom 7 than angle β. The discharge port 5 for the product is provided in the
flat portion 4", so as to further facilitate the flaking off and delivery of the granular
product in use of the dispenser.
[0032] In the dispenser of this invention, the side walls actually define a funnel-shaped
section in the tray, but the discharge port 5 is formed laterally in said funnel-shaped
section, i.e. through a side wall rather than the bottom as in the state of the art.
[0033] In this way, the product aggregation and packing at the tray bottom, which made its
issuing out of conventional dispensers practically impossible, is avoided.
[0034] In the dispenser of this invention, the port formed in a side wall has proved effective
to promote the flaking off and the regular delivery of the product as required.
[0035] Of course, the port 5 in the wall 4" would also be covered with a self-sticking or
heat-sealed label adapted to be torn off.
[0036] In a preferred embodiment, shown in Figure 3, the tray container of the dispenser
1 is boat-shaped.
[0037] Advantageously, the discharge port 5 for the product is provided in the pointed forward
end of the boat shape.
[0038] Here too, the port 5 is covered with a label 6, and a stopper 11 for re-closing the
container is provided for quick application to the port 5.
[0039] In this particular embodiment, a side wall 12 of the tray-type container 2, located
opposite from the side wall 4 with the port 5, advantageously extends almost square
to the container bottom 7. This allows the dispenser 1 to stand upright on said wall
12.
[0040] Alternatively, a pad 13, located at the container bottom 7, may be associated with
the wall 12 of the tray-type container 2 opposite from the side wall 4. The pad 13
has preferably an adhesive-coated surface for quick attachment to the side wall 12
of the dispenser 1, and is useful to prop up the dispenser 1, such that the latter
can rest upright on the top edge of the wall 12 and the pad 13.
[0041] Another embodiment of the dispenser 1 according to the invention will now be described
briefly with reference to Figure 4.
[0042] In this embodiment, the dispenser 1 is cup-shaped as at 16, and the port 5 is provided
in a flat portion 14 of the cup side wall close to the cup bottom 15.
[0043] Here again, the cup-shaped container is made from a thermoformed transparent multi-layer
sheet, and closed at the top with a sheet cover 3 of a synthetic material, which is
heat-sealed around the cup rim.
[0044] In addition, the port 5 is covered with the tear-off label 6, which label will then
leave the place to the stopper 11 for re-closing the dispenser.
[0045] The dispenser of this invention does solve the technical problem, and affords advantageous
features, foremost among which is that it doubles as a container for the long-term
storage of food products under an inert atmosphere, and as a uniquely serviceable
dispenser.
[0046] In fact, the grated product is allowed to run out smoothly and controllably, and
even in the event of a product with a high moisture content tending to aggregate into
lumps, a gentle shaking of the dispenser is enough to restore the product to its loose
granular form for an efficient delivery.
[0047] In all conditions of use, the product will always be discharged through one side,
and will not crowd toward the discharge port under its own weight, as is instead the
case with conventional dispensers.
[0048] All of the above-described embodiments of the container according to the invention
are suitable for a very large volume production and for being filled and sealed by
means of currently available automatic filling apparatus.
[0049] Furthermore, the dispenser of this invention allows the food products packaged in
it to be preserved and used for a relatively long time after the package is unsealed.
