This invention relates to a device for holding and transporting at least one container containing a food product, in particular one required to be kept at a temperature below ambient temperature, such as ice cream. It also relates to a freezer designed to hold such a device.
The purpose of this device is to present, serve, temporarily insulate from the ambient heat, and optionally re-cool the contents of commercial ice cream containers and to stiffen the containers. Ice cream is given to mean any sweet or even savoury finished frozen food product principally based on water or milk. These containers can be taken out of a domestic freezer but can also be kept inside the freezer.
Conventionally, containers are taken out of the freezer one by one and it is not very easy to remove scoops of ice cream using a spoon as it is difficult to immobilize the containers. Moreover, the containers are thin and sharp for the fingers. This is aggravated in particular by the fact that the container manufacturers generally do not wish to produce them in a plastic that is too thick, since these containers are used only once. Moreover, it is not very practical to have to put them back into a freezer as rapidly as possible, only to bring them out again a short time later for further consumption. Moreover, it is not hygienic to leave these containers standing on a table as their contents must not be refrozen after defrosting. During the summer when it is very hot, it is sometimes difficult, even using an insulated bag, to bring back ice creams from the freezer cabinet of a supermarket without them melting slightly.
Moreover, it is often quite difficult to remove ice cream from a container without causing it to deform or move. One aim of this invention is thus to propose a device designed to prevent a container from lifting when the user scoops the ice cream in a movement from bottom to top.
The object of this invention is to remedy these drawbacks and to attain this objective by proposing a device for holding and transporting one or more containers containing a food product which must be kept at a temperature below ambient temperature, such as ice cream. The device comprises a thermally insulated chamber and an insulating lid.
According to the invention, the device also comprises:
means of retaining said container within a housing provided in said insulated chamber when a user removes product from said container, and
essentially flat means of receiving the pressure of a hand or the fingers of said user, arranged on the upper part of said device.
These retaining means can be made by using a means of gripping and compressing the container under a collar which is often provided on the containers. Each container can be restrained below its collar to immobilize it in all directions, in such a way that the removal of ice cream using a spoon does not lift the container. The collar then acts as a stop. In particular, a collar can be used to hold the container during the filling process.
A device can also be envisaged comprising a housing which favours the flaring of the flat parts of the container outwards rather than inwards. A slight outward flare can be produced by realizing a impression which is slightly oval.
The immobilization of a container can be reinforced by compressing and gripping it in a part of the housing which is the impression of the specific shape of the container. This gripping can be carried out at the level of a collar that is often provided on the containers and which abuts against the upper face of the chamber when a user inserts a container into a housing.
In order to achieve this gripping and compressing effect, provision can be made for the edge of the housing in the upper part of the chamber to be flexible and for its dimensions to be slightly smaller than the part of a container situated just below the collar.
With this compression, an additional aim is to compensate for the dimensional variations resulting from manufacturing and the effects of expansion, and to prevent the container from coming out of its housing when the user performs a scooping action with the spoon in the ice cream from bottom to top.
A device for two containers, with two insulating lids, can be envisaged.
In this configuration, firm pressure can be exerted on an insulating lid with the whole hand to press the device down onto its support, while scoops of ice cream are removed with the other hand.
A device can also be envisaged with a single, larger, insulating lid. In this configuration, the device, without its insulating lid, is pressed down by applying pressure between the two containers, which produces a comfortable position for the hand.
Two container lids are arranged on the insulating lid. A third lid can be placed on one of the two containers for exerting firm pressure (with the whole hand) and pressing the device down onto its support. The ice cream can then be removed from the other container. Then it is simply a matter of placing the lid on the other container, performing a 180° half-turn and removing the ice cream from the other container. This achieves a particularly comfortable position for the hand exerting pressure.
It is possible for the third lid to have no label, to avoid any risk of confusion about the types of ice cream stored. This lid can optionally be insulated.
The device can be pressed down on its support using the hand in a comfortable position, in particular by pressing with the whole hand (hand flat) on a container lid mounted on a container, to remove the ice cream from the other container.
In a particular version, a container is extended by an ergonomic part providing a space for resting the palm of the hand in an ergonomic manner. This ergonomic part is preferably provided with a reinforcing rib.
It is possible to envisage a cold accumulator that is optionally detachable, comprising an impression of the bottom part of the container, which contributes to reinforcing the immobilization of the container and requires the use of containers compatible with the impression of the accumulator.
The cold accumulator is preferably a low-temperature accumulator that recharges at −18° C. The liquid contained in this cold accumulator can advantageously be a mixture of ethyl alcohol and water in the proportion of approximately 18%.
The device according to the invention is advantageously designed to be placed as a whole in a freezer.
It can be envisaged that several devices according to the invention can be stacked, in particular to minimise the space occupied on a table and for transportation.
The upper part of the insulated chamber can be provided with a recess opening upwards and onto the housing, to allow a user to lift and remove manually either the container or its lid, or both at once.
The lid of a container can be fastened on the insulating lid according to a fastening method similar to that of a lid on a container, and a recess can be provided in the insulating lid to allow a user to remove the container lid manually from the insulating lid.
The insulated chamber and the insulating lid can be separately watertight against splashing and immersion, thus allowing each element of the device according to the invention to be washed in hot water or in the dishwasher, including the cold accumulator in its detachable version.
In a particular embodiment, the insulating lid can have a partially open position on the insulated chamber, thus allowing thermal equilibrium between the inside and outside of the insulated chamber, which has the effect of cooling the ice cream when the user places the device according to the invention in a freezer with its insulating lid in the partially open position.
The thermally insulated chamber can advantageously comprise at least one housing in which a container is immobilized when a user inserts it into this housing, allowing easy removal of the ice cream contained in that container.
It can be envisaged that the device according to the invention comprises projections arranged on the bottom of the insulated chamber, in such a way as to distance the bottom of the container from the bottom of the chamber, thus providing a layer of air which communicates by vertical ducts with the cold air of a freezer in which the device according to the invention has been placed, or with the warm ambient air to soften the ice cream for easy insertion of a spoon.
In another embodiment envisaging greater freedom of use, the device according to the invention can also comprise means of cold accumulation to allow the contents of the ice cream containers transported in this device to be re-cooled. These cold accumulation means can comprise a watertight casing containing a freezing liquid.
The cold accumulation means can advantageously comprise one or more housings shaped for holding containers and having for this purpose a full or partial impression of the specific shape of these containers.
These cold accumulation means are re-cooled each time the device according to the invention is placed in a freezer, with its insulating lid partially open. Outside the freezer, the cold accumulation means transfer their frigories to the ice cream contained in the containers stored in the device according to the invention and in thermal contact with the cold accumulation means in the insulated chamber.
The cold accumulation means can be of the low-temperature type, with latent energy transfer at approximately −18° C. The freezing liquid can be a mixture of water and ethyl alcohol proportioned so that the latent cold produced by the liquefaction of the frozen mixture is returned principally at a temperature just above the temperature of ice creams on removal from a freezer, i.e. −18° C.
In this other embodiment including cold accumulation means, provision can advantageously be made for the device according to the invention to be provided with projections, either on the bottom of the accumulation means, or inside the bottom of the insulated chamber, which have the function of distancing the bottom of the accumulation means from the inside of the bottom of the chamber, thus creating a layer of air in communication via vertical ducts with the cold air of the freezer. Thus the cold accumulation means can be cooled by a greater surface area for thermal exchange.
Still in this other embodiment, means can also be provided within the device for positioning a container, either in a lower position or an upper position, a container being in thermal contact with the cold accumulation means in the lower position, while in the upper position, a layer of air is created between the bottom of the container and the cold accumulation means and is in communication with the cold air of the freezer via vertical ducts. This layer of air also allows more rapid warming in the ambient environment, for example of the ice cream, in particular if there is an accumulator.
The device can be integrated into the upper part of a horizontal opening freezer, just under the door when it is closed. In this case, the device according to the invention is retractable from its horizontal position of use which obstructs the freezer when the door is open, in order to allow access to the underlying internal space of this same freezer.
According to another feature of the invention, a freezer is proposed comprising an insulated chest equipped with a horizontal opening, an insulated hinged door and a system for freezing the contents of the chest, which can be equipped with retractable means forming a tray for holding and immobilizing containers of food product, in particular ice creams on sale in a shop. This freezer is insulated by the tray when its door is open for the consumption of ice creams.
The tray can be articulated to the freezer by means of a hinge, in the same way as the door on this same freezer. This tray can be retracted by pivoting it manually around the hinge from its horizontal position of use to a vertical or oblique position, and can comprise a projecting lip.
In a freezer according to the invention, a recess in the form of a channel with a U-shaped cross-section in which the projection of the tray rests in a vertical or oblique retracted position can constitute the hinge, making the tray detachable.
The door of the freezer according to the invention can comprise internally a stop or a fastener. Thus in its vertical or oblique retracted position, the tray containing the containers and the door of the freezer each form with their hinge and the stop or the fastener, an indeformable assembly which is in stable equilibrium, in such a way that the user has their hands free for accessing the freezer.
The fastener can be a clip or a spring pin in which a part of the tray in the form of a bulge is lodged, when the user retracts the tray. The tray is released from this retracted position when the user presses on the edge of the pin to open it. The user supports the tray in its tilting movement. The part of the tray in the form of a bulge can also be used as a carrying handle for the detachable device.
The freezer according to the invention can comprise specifically for the incorporation of the tray;
a heat seal situated in the opening of the chest between the tray and the freezer;
a recess in the form of a channel with a U-shaped cross-section constituting the hinge of the tray,
a clip or spring pin fixed to the inside of the door,
a recess beneath a tab of the tray for a hand-hold before the tray is retracted.
Other advantages and characteristics of the invention will become apparent when examining the detailed description of an embodiment which is in no way limitative, and the attached drawings, in which:
With reference to
The assembly thus formed is itself captive between two plastic half-shells 15 and 16, formed in a single operation by injection moulding. The lower component 16 constitutes the bottom of the tray, and the upper component 15 is moulded according to the external shape of the containers as regards their thickness.
Between a container 3 and the accumulator 33, an air gap is left, the depth of which is fixed in relation to the desired thermal conduction between these two elements. This space can optionally be nil and the two components 15 and 16 are mounted fixed or clipped onto each-other, with reference to detail M in
The insulating caps or lids 26 can be constructed on the following principle: a moulded insulating component 29 (
The lower component 127 comprises conical braces 130 to prevent the crushing of the captive moulded insulating component. The lower component 127 has a shape that allows the lid 26 to be clipped or fastened onto the container like a cover on a container, with reference to
As a non-limitative example, the tray 1 can comprise two containers and have dimensions of approximately 30 cm in length, 20 cm in width and 10 cm in height.
With reference to
The component 125 of the tray 1 comprises, in the housings 2, watertight bases 121. Thus it is possible to wipe the tray clean without the water running into the freezer beneath. Moreover, this tray has internal reinforcing partitions 120 and a tab 112 by which it can be held. It comprises cavities 18 for extraction of the containers 2 and cavities 18 for extraction of the lids 25 only, with reference to details E and F in
The freezer 104 that incorporates this tray variant comprises specifically:
In this embodiment and in its horizontal position for use, the tray 1′, by means of its chamfer 122, rests on the trapezoidal seal 123, leaving a functional clearance J1 between the projection 35 and the component 36 of the freezer.
A description will now be given of a method of use of a device according to the invention, with reference to
On arriving at home, the consumer opens the device, removes the lid 8 of the container and transfers it on the insulating lid 9 which is then placed in the partially open position (
After taking the device out of the freezer, the consumer removes the container from it (
The insulating lid 9 is then replaced on the device as shown in
The device according to the invention is finally replaced in the freezer in the configuration shown in
With reference to
Instead of removing the container from the device, the latter is lifted into an upper position (
With reference to
With reference to
Several methods of assembly can be envisaged for producing the insulating lid and the insulated chamber. Thus, with reference to
With reference to
The insulating lid 9 is made according to the same principle, with reference to
The accumulator 20, which is a hollow plastic casing, is blown into a mould in two parts in the same way as a plastic bottle, with reference to 17B and 17C. The profiled part 13 in the form of a flange, the part with the pointed profile 30, as well as the profile 7 serving to grip the container in its housing, which would be difficult to achieve in the blowing operation, are added on by overmoulding, with reference to
The user exerts leverage with both hands in the recesses 6 by holding the container between the thumb and the index finger, producing rotary movements around the index fingers (
It should be noted that the passage of air between the insulating lid 9 and the insulated chamber 1 takes place above a duct 23, at the point where the profiles 7, 13 are interrupted, with reference to
The cold accumulator 20 comprises projections 27 produced by moulding, which are appropriately arranged and in sufficient quantity so that the chamfers 22 allow for the accumulator to be guided on insertion into its housing. The housing 2 as well as the ducts 23 are produced by moulding. An opening is provided for filling the accumulator with a mixture of water and ethyl alcohol at 18% approximately, then plugged in a watertight manner.
A sufficient flat surface is provided on the upper part of the insulated chamber to allow the fingers of a user to be positioned when he presses the device down on a stable support (
In one configuration of a device designed to hold two containers, shown in
To fasten a container in the device when the insulating lid has been removed from the chamber, the user simply exerts with is fingers a downward force on approximately the four corners of the lid of the container, as shown in
Of course, the invention is not limited to the embodiment described and variations can be made thereto without exceeding the scope of the invention. In particular, although the invention has been described more particularly with a stop for the container on the device below the collar, the stop can also be made on the bottom of the container or at any level in the thickness of same, even if the container has no collar.
Although it is described for holding containers of ice cream, the device can also contain an ice cream Yule log. In this case, only the insulation function is retained. A device according to the invention can also be used for holding containers of doughy substances at ambient temperature.
Moreover, the insulating lid can be designed to be hinged on and detachable from the insulated chamber by means of at least one hinge, and can adopt a partially open position from the closed position by a rotation of several degrees. This provision has the advantage of avoiding loss of the lid inside the freezer and minimising the space occupied by the device on a table when the lid is opened at 90°. If systematically adopted, the device according to the invention could have ecological advantages. In fact, since the containers used in this device no longer require great rigidity, they could therefore be made from biodegradable material, for example rice starch.
