The present invention relates to the field of food products' packaging, and specifically to a packaging designed to contain food products that are ready to be eaten or ready for preparation and that consist of two or more components to be mixed together before use.
For instance, the invention may be used to mix vegetables with their dressings, pasta with sauces or gravies, bread-crumbs % kith beaten eggs (for the preparation of omelettes), meat or fish with their coverings of bread-crumbs (for the preparation of fried dishes), and so on.
Therefore, the invention is not only useful for the final user, that is, for the person who will actually eat the food product, but could be employed in the kitchen of a restaurant, or in the domestic environment, in order to facilitate or speed up the preparation of food products that precedes their successive treatment (e.g. frying, cooking inside a microwave oven, etc.).
At present, there are known various kinds of packaging for ready-made food products, that are used both in the domestic and non-domestic environment. These kinds of packaging include a plastic-made container (receptacle) which is open uppwardly—like a bowl—, and which is completely wrapped by a sealing film of cellophane or the like.
The container has at least one compartment for a first food component to be seasoned, and at least a second compartment for small bags (sachets) containing a sauce or the like.
The user that has removed the external seating film (or possibly an upper cover of the container) opens one or more sachets available to him, after taking them from the respective compartment, and then pours their content in the compartment that contains the food product to be seasoned.
A drawback of such a packaging for food is that it is very easy to inadvertently pour the content of the small bags on one's clothes or on other objects, and therefore this operation is not very convenient and hygienic to carry out. Moreover, since the food to be seasoned usually occupies (due to space optimisation) the whole volume of its respective compartment (forming the greatest part of the volume of the packaging), the operation of seasoning the food product (e.g. salad) is very difficult, if not impossible to carry out, if one wants to avoid to pour (spread) the food product out of the already opened packaging.
Therefore, an object of the present invention is to provide a packaging for food, that allows to mix the various components of the food in a hygienic and efficient way.
The use of compartmented storage containers is known in the prior art. For example, European Patent Number EP 0790190; Great Britain Patent Number GB 2,211,479 A; U.S. Pat. No. 4,793,476.
The above objects are attained according to the claims, by means of a ready-made dish disposable packaging with several compartments:
an upwardly open container (1), an upper closure element (A) of the container (1), a compartment (2) of the container (1) for a first component of the food product, and at least an additional compartment (3) that is realised integrally with the container (1) or is rigidly fixed thereto in a non-removable manner, and which is used for an additional component of the food product to be mixed to said first component, said additional compartment (3), which is initially sealed, having movable members (13, 14) that may be actuated by the user from outside the container (1) and which realise a communication path between the compartment (2) and said additional compartment (3), thereby allowing to mix the first component of food product, located inside the compartment (2), to the additional component of food product coming from the additional compartment (3), said movable members being formed by a base (13) of said additional compartment (3), that is connected by means of a hinge (15) to the walls (9) of the compartment (3), and said base (13) being movable between a first- or rest-position, and a second position, whereby during the displacement to the second position the base acts on a movable plug (14) which slides along the walls of said additional compartment (3); said plug (14) having lateral apertures which give rise to said communication between the compartment (2) and the additional compartment (3), in said second position of the movable base (13), when said plug (14) has reached a second, final position, without releasing itself from said walls (9) of the compartment (3).
The above objects are also attained by a combination between a disposable packaging for a first component of a food product, and a separate and sealed container (24) for a second component of the food product, in which:
the packaging comprises a container (1) with an upper closure element and a lower closure element, a compartment (2) for the first component of the food product in which said components are to be mixed together, and a coupling hole (11″) for the connection to said sealed separate container (24);
the initially sealed container (24) has movable piston-like members (13′, 14) that are actuated by the user and realise a communication path between said compartment (2), and an additional compartment (3) defined by the separate sealed container (24) itself, after the removal of the lower closure element, after the mechanical coupling of the separate sealed container (24) to the coupling hole (11″), and lastly, after the actuation of said movable members (13′, 14), said movable members are formed by a base (13′) of said additional compartment (3), connected by a hinge (15′) to the walls (9′) of the compartment (3), and wherein said base (13′) is movable between a first- or rest-position, and a second position, and during the displacement to the second position the base acts on a movable plug (14) that slides along the walls of said additional compartment (3); the said plug (14) having lateral apertures which give rise to said communication path between the compartment (2) and the additional compartment (3), in said second position of the movable base (13′).
As disclosed in more detail, the movable members could also be designed to break the sealing means of the additional compartment, and form—for instance—a push rod or pointed rod having an oblique upper end, designed to break a sealing plastic/aluminium film of the additional compartment.
The pointed rod or push rod is preferably integrally formed with the container during the plastic moulding process.
The push rod has longitudinal channels in order to facilitate the leaking of the sauce, dressing, or the like, from the additional compartment.
The advantages of the present invention will result from the detailed description of its preferred embodiments.
The present invention and its specific advantages will be described for purely illustrative and non-limitative purposes, with reference to the accompanying drawings, in which:
a and 4b are vertical sectional views of the invention, corresponding to an embodiment of the present invention;
The present invention will be described referring to
Then, we will describe the embodiments of the present invention, with reference to
In all figures the same reference number is used for an identical component of the packaging, so that the invention may be more readily understood.
The packaging essentially comprises a container 1 which for instance is obtained from a moulding process of plastics.
The configuration of the container 1 is such as to give rise to two separate compartments, denoted by 2 and 3 respectively. The compartment 3 is centrally located and has a cylindrical shape, while the greater compartment 2, that surrounds the compartment 3, has a substantially prismatic and polygonal shape with several congruent faces. Obviously, these shapes of the compartments are not limitative, and the same holds for the position of the compartment 3, although for a more uniform distribution of the food product component contained in the compartment 3 towards the inside of the compartment 2, containing the other component of the food product, the preferred position is the illustrated one.
The container 1 is formed by:
an upper flange 4, on which a sealing film is applied (not shown), e.g. by heat sealing, ultrasonic welding, adhesives, or any other possible sealing method suited to close the open upper part of the container 1;
a side wall 5 with facets (or faces) having a polygonal horizontal section, the side wall terminating at its lower end in an annular projection 6—also visible in FIG. 7—;
an annular lower planar surface 7—formed on said projection 6—, to which a second sealing film is applied (not shown) by any known sealing method;
a base wall 8, extending from the internal upper end of the annular projection 6, to a cylindrical wall 11 (11″ in
a movable base 13 (13′ in
Moreover, some pieces of cutlery (e.g. of plastics) or other fittings (e.g. napkins), or additives of the food product, may be received in the annular recess 10 and are retained from below by said film (not shown) which is applied on the planar annular surface of the annular projection 6 (
In an embodiment the container 1 is integrally formed (e.g. of moulded plastics). However, the plug 14 forms a separate piece (e.g. of plastics).
It must be stressed that the plug 14 has been omitted for clarity in
To better understand the structure and operation (use modalities) of the packaging according to the present invention, reference will now be made in particular to the
The latter figures are representations in vertical section, limited to the central portion of the container 1, and in particular they show the cylindrical wall 9 of the compartment 3 which contains the sauce or dressing, the lower extension 11 of this cylindrical wall, the circular hinge 15, and part of the base wall 8. Moreover, the plug 14 is inserted (in the initial rest position of
The movable base 13 for the actuation of the plug 14 includes centrally a cylindrical rib, or annular cylindrical portion 16, that is integrally formed on the movable base 13. Said circular rib 16 receives (e.g. by press-fitting) the lower portion of an axial stem 17 of the plug 14. Moreover, the plug 14 has two circular peripheral grooves 19a and 19b, which are parallel to each other, and the upper end of the cylindrical wall 9 has a (inwardly directed) circular bead or ridge 20 complementary to the shape of the grooves 19a and 19b, adapted to engage with the upper groove 19a in the closing position of the plug 14 (
The exact configuration of the plug 14 may be inferred—besides from FIGS. 5 and 6—also form
First of all, the user of the packaging shown in
In the preceding description it is assumed that the words “upper” and “lower”, and “upwards” or “downwards”, refer to the orientation of the packaging (and therefore of the container 1), that is shown for example in
Without removing the cover (or the upper film), the user turns over the packaging in order to allow the complete downflow of the sauce, or dressing, or bread-crumbs, etc. through the “windows” or apertures formed between the small rods 22. Then, the user shakes the packaging in order to perfectly and uniformly dress a salad, for instance.
At that time, if the food product (e.g. a salad) can be immediately eaten, the user simply removes the upper sealing film or an upper cover, and can directly use the compartment 2 as a bowl.
On the other hand, in case of a food product that must be fried, the user (in this case a cook) must tear the upper film and pour the content in a frying-pan or the like. However, in case of a microwave oven, it will be possible to directly employ the container 1 as a cooking container.
Therefore, it can be seen that the objects of the invention are fully attained. Particularly, it will be impossible to pour the seasoning out of the container 1, since the upper film will not be removed, except when the seasoning operation is completed. Moreover, the sachets (small bags) of the prior art are totally superfluous, and the space inside the compartment 2 may be better used.
Now, we will describe an alternate embodiment of the packaging present invention, referring to
In the embodiment, shown in
The movable base 13′ for the actuation of the plug 14 has centrally a cylindrical rib, or cylindrical annular portion 16′, which is integrally formed on the movable base 13′ of the cartridge. Said circular rib 16′ receives (e.g. by press-fitting) the lower portion of an axial stem 17′ of the plug 14. Moreover, the plug has two peripheral circular grooves 19a′ and 19b′, that are parallel to each other, while the upper end of the cylindrical wall 9′ has a (inwardly directed) ridge 20′, having a complementary shape with respect to the shape of the grooves 19a′ and 19b′, and adapted to fit inside the upper groove 19a′, in the closing position of the plug 14 (
The exact configuration of the plug 14 may be inferred, besides from
Moreover, it can be noted that the various vertical rods 22′ of the plug 14 are arranged at equal angles along the periphery of the flanged disc 21′ that forms the upper part of the plug 14. Thus, the small rods 22 form “windows” of equal dimensions, which are clearly visible in
According to this solution, the final user can freely choose the seasoning/dressing he/she prefers, by independently purchasing a separate container 24 sealed by the respective plug 14, and containing the desired type of seasoning, dressing or the like. Then, after having turned over the packaging, he/she removes the lower sealing film and inserts the separate container 24 (sealed by the respective plug 14) inside the hole of the container 1, defined by the cylindrical sleeve 11″. Then, the user simply has to push the movable base 13′ inwardly, to the inside of the container 1, and shake the packaging.
Also in this latter solution, the seasoning or the like cannot leak out of the packaging, since the upper sealing film (or the cover) is removed in the last step, that is at the end of the operation.
The invention has been described only for illustrative purposes with reference to its preferred embodiments. It goes without saying that various modifications may be conceived by a skilled person, within the same scope of protection.
For example, the number of compartments 3 is not limited to a single compartment, and if desired, more compartments could be provided if for the preparation of the food product it is necessary to mix together more than two components that must maintained in a separate state up to the preparation time.
Now, an alternate embodiment of the present invention will be described.
The embodiments are similar in that the compartment 3 does not form a separate element (in contrast with the cartridge 24 that can be inserted in the container 1), but is connected to the container in a non-removable manner.
With reference to
It should be noted that the container 1a is formed by a thin wall of plastics, that has been adequately shaped in the moulding process, said thin wall being horizontal at the base 8a of the container 1a, and vertical at the cylindrical external wall 5a and at the cylindrical wall 9a of the inner dressing's compartment 3a.
The thin cylindrical wall 9a extends upwards only for a reduced height as compared with the external cylindrical wall 5a, and then it extends downwards so as to form a kind of “well”; the latter gives rise to the compartment 3a that contains the dressing, or seasoning, or bread-crumbs, etc. Centrally, the compartment 3a has a push rod or pointed rod 14a, which internally is hollow, and is formed again by said thin wall of plastic moulding material. Thus, the container 1a is really formed of a single moulded piece of plastics, consisting of a thin wall having the described configuration.
The push rod 14a therefore forms an element having a shape like a frustum of a cone, which is internally hollow (see blind hole 14b), and which is itself formed by said continuous thin wall. Due to the presence of the push rod 14a, the seasoning will occupy—inside the compartment 3a—, an annular substantially cylindrical region, as may be clearly seen in
Even in this embodiment the seasoning or the like is stored separately from the ready-made food product, since a sealing film 14c is provided at the upper side of the compartment 3a and is applied laterally—on the circular step 20a—. Moreover, the container 1a is sealed at its upper end by a film A, or by a removable cover made of plastics or the like, that temporarily hermetically doses the container 1a.
The only difference between
Also in this case the object of the invention can be immediately recognised by the following description of its use.
When the packaging is still sealed, that is before removing the sealing film A from the upper part of the container 1a, the user presses with his/her hand on the bottom 13a of the seasoning's compartment 3a, so as to deform the thin wall of the container at the location of this inner compartment 3a, as shown in
For completeness, and referring again to
In
The advantages of the present invention are obvious to the skilled person. In fact, the packaging must be opened only shortly before the food product is eaten, and the system guarantees a perfect dressing.
Although the invention has been extensively described with regard to only some distinct—but specific—embodiments thereof, a skilled person may easily imagine several constructive modifications without thereby arriving at results out of the scope of protection conferred by this document.
The structure of the packaging may also be more complex. The container could—for instance—comprise a sealing and removable cover in lieu of the film A, and/or a sliding push rod 14a which slides with respect to the base 13 of the compartment 3a. All these modifications are obviously within the reach of the ordinary skilled person that has taken cognisance of the solutions proposed herein, and for this reason they are to be considered included in the present invention.
