Description

Title of the invention: PORTABLE FOOD PASTE EXTRUSION APPARATUS Technical field

[0001] The invention relates to the field of utensils and apparatus for extruding food dough through a nozzle, commonly used in the field of pastry making. Prior art

[0002] In the prior art, flexible piping bags are conventionally known in which a reserve of paste is manually pressed to be distributed through the nozzle. Here, the term "paste" refers to all pasty products, creams, malleable ingredients and the like capable of being extruded through a nozzle provided on an outlet end of a reservoir. The user using this type of bag must use both hands with a certain dexterity and must exert an effort that is difficult and not ergonomic, and this is more acute for a person suffering from musculoskeletal disorders.

[0003] We also know a portable biscuit-making device comprising a reservoir in which a dough is pushed through a socket using a piston movable by an electric motor. Such a device is sold under the brand Ozio (R) on the Amazon (R) website. This device has a cylindrical reservoir in the extension of the gripping area which is also cylindrical, and is provided with an on-off button located in the gripping area which implies that the hand covers the gripping area with precise covering of the on-off button by the tips of the fingers activating this button, which is not very intuitive. This device offers simple on-off use, which is not suitable for all use cases and requires repeated pressure which is not convenient and ergonomic.

[0004] There is therefore a real need to propose a portable food paste extrusion device which overcomes the previous drawbacks and significantly improves the ergonomics of use. Statement of the invention

[0005] The aim of the invention is to improve the portable food paste extrusion devices of the prior art and to propose a device better suited to users suffering from handling difficulties, or simply requiring a more ergonomic device.

[0006] To this end, the invention relates to a portable food paste extrusion device comprising a main body integrating an electric motor controlling the translation of a push rod inside a reservoir receiving the paste attached to the main body, the push rod having a free end provided with a wall exerting pressure on the paste to extrude it via a socket located at one end of the reservoir opposite the main body, characterized in that the main body is extended by a handle extending transversely to the general cylindrical direction of the reservoir to constitute a gun base, the apparatus comprising a trigger for activating the motor and its locking means, control means being provided to adjust the speed of movement of the rod as well as the durations of movement and pause during its movement.

[0007] Very advantageously, once the settings have been made, the device requires no finger movement or pressure. The user only has to hold the device and concentrate on his work of automatically extruding the ingredient when the automatic mode is selected, applying the product to the desired area precisely and effortlessly. This assembly allows people with disabilities or difficulties with mobility of the hands, fingers and wrists to carry out all the work required by the use of a pressure piston. The shaping of all types of pastries, such as chouquettes, éclairs, acorns, Paris-Brest, other fillings and dressings will not reveal any difficulty.

[0008] With the available settings of the control means, production respecting the desired grammage is possible. The pastries will be identical and the loss of ingredients minimized.

[0009] Small-scale or artisanal production is possible. Control of dough and filling weights is ensured, as is the resting time.

[0010] Of course, the device also has a manual mode allowing you to return to on / off operation, with the possibility of locking in on mode.

[0011] Other advantageous characteristics of the invention are detailed below:

[0012] - the reservoir has the general shape of a cylinder of revolution whose diameter is between 50 and 80 mm, and the length is between 150 and 300 mm, especially 250 mm.

[0013] - the tank is fixed to the main body () by a rotating bayonet system im performing a rotation of an angle A of between 10° and 100°, in particular approximately 20°, of the tank relative to the main body to move from a tank unlocking position to a tank locking position.

[0015] - the control means include:

[0016] - a manual or automatic mode selector,

[0017] - a rod movement duration selector,

[0018] - a pause duration selector during movement of the rod.

[0019] - the control means include:

[0020] - a rod movement speed selector allowing to control the minus a fast speed and a slow speed considered relative to the fast speed.

[0021] - the device comprises return means, in particular with manual traction exerted on a tip of the rod, allowing the rod and the wall to be arranged in a position opposite the socket.

[0022] The invention also relates to a method of using a portable pasta dispenser comprising a main body incorporating an electric motor controlling the translation of a push rod inside a reservoir receiving the pasta attached to the main body, the push rod having a free end provided with a wall exerting pressure on the pasta to extrude it via a socket located at one end of the reservoir opposite the main body, the main body being extended by a handle extending transversely to the general cylindrical direction of the reservoir to constitute a gun base, the handle comprising a trigger for activating the motor, control means being provided for adjusting the speed of movement of the rod, characterized in that, in an automatic operating mode, it comprises a successive sequence of alternating movements and pauses of the rod,each movement being carried out at an adjustable speed and for a predetermined adjustable duration, while each pause also corresponds to a predetermined duration adjustable independently of the duration of movement.

[0023] According to other advantageous characteristics of the method of the invention:

[0024] - the speed of movement of the rod is between 4 and 10 mm / s,

[0025] - the duration of movement of the rod is between 1 and 5s,

[0038] [Fig.9] is a diagram indicating the weight of food paste deposited in function of the duration of the trigger press, in impulse mode (top) and in blocked mode (bottom). Detailed description

[0039] [Fig.l] shows a portable apparatus 1 for extruding food paste according to the invention. This apparatus comprises a main body 2 incorporating an electric motor (not shown) controlling the translation of a push rod 3 inside a reservoir 4 receiving the paste. This reservoir 4 is attached to the main body 2. The push rod 3 has a free end provided with a wall 5 exerting pressure on the paste to extrude it via a sleeve 6 located at one end of the reservoir 4 opposite the main body 2.

[0040] The drive of the push rod 3 by the motor is carried out by a rack and pinion system. The rack is shaped along the rod, while the pinion is driven in rotation by the electric motor, directly or indirectly by gear reduction means.

[0041] As shown in Figures 1 and 2, the main body 1 is extended by a handle 7 extending transversely to the general cylindrical direction X of the rod 3 and the reservoir 4 to constitute a gun base.

[0042] The apparatus comprises a trigger 8 for activating the motor and its locking means 9 in the activated position. Control means are provided for adjusting the speed of movement of the rod as well as the movement and pause times during its movement in the longitudinal direction X.

[0043] The electric motor is powered by 9V direct current (DC). In one embodiment of the invention, the power supply is provided via an external 9V DC electrical transformer and connected via a 5.1x2.1 jack connector typically located at the end of the handle 7 via a suitable connector. In another embodiment of the invention, the power supply is provided via an external battery attached to the main body or to the handle 7.

[0044] The reservoir 4 of the device has the general shape of a cylinder of revolution whose diameter is between 50 and 80 mm, and the length is between 150 and 300 mm. In the example shown, the length of the reservoir 4 is typically 250 mm. This length corresponds substantially to the maximum stroke of the rod 3 and the wall 5 inside the reservoir 4. In a preferred example, the reservoir has a diameter of 80 mm and a capacity of 1200 ml.

[0045] Of course, several tank sizes are possible without departing from the scope of the invention, for example a diameter of 50mm and a length of 200mm, this in order to limit the weight of the entire device in use.

[0046] This ingredient container is closed at one end by an adapter lid with nozzles or biscuit discs. After use, it can be closed by two airtight lids, or by an airtight lid and a nozzle covering the nozzle which will allow the remaining preparations to be stored in the refrigerator before using them again. The container is made of a rigid material resistant to temperatures up to 100°C and has graduations in ml and oz.

[0047] With reference to [Fig. 3], the reservoir 4 is fixed to the main body 2 by a rotating bayonet system involving a rotation of the reservoir 4 relative to the main body 2 to move from an unlocking position of the reservoir 4 to a locking position of the reservoir 4. This rotation around the longitudinal axis X is by an angle A of between 10° and 100°. In the example illustrated, the angle A is of the order of 20°. The rotating bayonet system is understood to have at least two radially opposite extensions (not shown) shaped on one end of the reservoir 4, these extensions penetrating axially into notches 10 of matching shapes on the main body 2, before being pivoted behind a rim 11 of the main body, until they come to a stop. The disassembly of the reservoir 4 is carried out in the reverse order.

[0048] As can be seen in figures 1, 2, 4, the trigger 8 is arranged along the handle 7. In the example illustrated, the means 9 for locking the trigger in the activated position is located on a lateral face of the handle 7 near the trigger 8. In a variant not shown, the locking means can be arranged in another area of ​​the handle 7 or of the body 2 suitable for right-handed or left-handed people.

[0049] [Fig.5] shows the top of the main body 2 on which the means of control of the device. These means of control are distinguished:

[0050] - a first selector 12 for manual or automatic mode

[0051] - a second selector 13 for the duration of movement of the rod 3,

[0052] - a third selector 14 for the duration of the pause during the movement of the rod 3.

[0053] Light-emitting diodes (LEDs) 15, 16 may be provided in connection with at least some of these selectors 13, 14.

[0054] With reference to [Fig.6], the control means also comprise a speed selector 16 (considered as a fourth selector) for moving the rod 3 making it possible to control at least one fast speed and one slow speed. The slow speed is considered relative to the fast speed.

[0055] The apparatus of the invention can therefore operate according to an automatic method (“AUTO” mode in [Fig. 5]) comprising a successive sequence of alternating movements and pauses of the rod 3. Each movement of the rod 3 is carried out at an adjustable translation speed and for a predetermined adjustable translation duration. The speed is adjustable using the speed selector 15. The duration is adjustable using the second selector 13. Each pause also corresponds to a predetermined duration adjustable independently of the movement duration. The pause duration is adjustable using the third selector 14. In another operating mode, the apparatus can also operate in manual mode (“MANU” mode in [Fig. 5]), the trigger then operating in an impulse manner. In this case and to facilitate use, the activation of the trigger 8 can be maintained by the blocking means 9 ([Fig. 6]).

[0056] As non-limiting examples of the invention, the speed of movement of the rod 3 is between 4 and 10 mm / s. Preferably, the speed of movement of the rod 3 is adjustable to at least two predetermined values, including a fast speed R chosen between 4 and 5 mm / s and a slow speed L chosen between 8 and 10 mm / s.

[0057] Also as non-limiting examples of the invention, the duration of movement of the rod 3 is between 1 and 5s, while the duration of pause of the rod 3 during its movement is between 0.5 and 3s. The term pause means a momentary stoppage of the progression of the rod 3, preceded and / or followed by a movement of the rod 3.

[0058] For example, a time of around 60 seconds is expected to empty 1200 ml of ingredient, with a push rod stroke of 250 mm.

[0059] [Fig.8] shows a table indicating the pushing times of the rod 3, up to 5 seconds, for a slow speed and a fast speed. In the upper table are indicated the strokes traveled by the rod 3 as a function of the speeds and the pushing times. The lower table gives for information purposes the volume and therefore the grammage of product deposited for each of these strokes of the rod 3. Each stroke and the associated weight typically correspond to the deposit of a quantity of dough or ingredient placed on a single culinary element to be prepared, for example a choux pastry, a pastry etc. A succession of movements and associated weights make it possible to successively deposit several quantities of dough or ingredients respectively on several culinary elements to be prepared.

[0060] Before any use, such an abacus can be consulted to adjust the speed and the movement and pause times of the rod 3, depending on the quantity of product to be deposited on each element to be prepared.

[0061] [Fig.9] illustrates at the top a sequence of movement of the rod 3 as a function of time, each column illustrating a press of the trigger 8 for a more or less long duration. The wider the column, the longer the press and the greater the quantity of product deposited. This diagram illustrates operation in manual mode (pulse). The diagram at the bottom of [Fig.9] also illustrates operation in manual mode, the trigger 8 being kept activated, either manually or using the locking means 9.

[0062] With reference to [Fig.7], the device comprises return means 17, in particular manual traction exerted on an end piece of the rod 3. A traction ball is arranged at the rear end of the rod 3, opposite the wall 5 and the sleeve 6, so as to form a gripping means for returning the rod 3 to its initial position.

[0063] The device is used as follows: - Placement of the appropriate socket at the end of the empty tank, - Filling of the tank (4) with the product (paste or desired ingredient), - Mounting the tank on the main body (fitting and fixing by the bayonet system), - Adjustment of the rod movement speed: slow mode “L” or fast “R” - Selection of automatic mode “AUTO” or manual mode “MANU” - Possibly adjustment of travel time and pause time - Placement of the product on the culinary element(s) to be prepared, continuously or sequentially depending on the mode chosen.
