The present invention relates to the technical field of accessories for pasty food products.
In the food service market, there are a large number of food establishments such as “cookies” industries, snack bars, restaurants, pizza stores and bakeries, that need to dispense gravies and/or fillings in controlled doses as a complement to other food products, for example, ready-made dishes, pizzas, sandwiches, chickendos, palmpanadas, and the like.
In addition to problems relating to the precise dosage of the pasty food products (so that the final product quality is maintained at a lower cost), there is an ongoing concern about food safety. Contamination of the dosing devices by the food product can occur while the product is being dispensed, which may result in the growth of pathogenic microorganisms. Therefore, conditions that may lead to the proliferation of pathogenic microorganisms must be avoided while the food product is being dispensed.
Presently, in this segment of the market, there are some forms of dosage that, according to the type of application, range from simple confectionery “sleeves” to equipment that uses a type of rigid packing with a moving cap that functions as a piston, thus allowing for the so-called controlled displacement dosing. In all these cases, however, the dosing process is either imprecise, unhygienic, or else requires packaging that is expensive compared to the price of the product. Oftentimes, it is a combination of such inconveniences.
Document BR202015019757-3, of the same applicant herein, published on Feb. 21, 2017, forms part of the state of the art. According to the abstract, “The present utility model is directed to a new constructive arrangement introduced in a pasty food dispenser, more particularly of pasty foods packed in sachets, pertaining to the technical sector of accessories for pasty food products, through which quite beneficial practical, safe and functional results are attained. The pasty food dispenser comprises a tubular body (1), whose front end is provided with a closure (2) and the closed end of which is closed by a trigger (3). Said closure (2) is formed by a ring-shaped body (21) that it is connected to the tubular body (1), provided with a joint (22) for the cap (23) and a lock (24) positioned opposite same. On the front face of the cap (23) are provided a slit (231), a triangular nozzle (232) and a retention valve (234) which, together with the triangular nozzle (232), holds the flattened tip (41) of the tubular sachet (4).

According to
Using the new pasty food dispensing and dosing device is very simple, efficient and hygienic. To use the device, first unlock the lock (3), open the cap (2) and insert the sachet (S) into the base (1), with the dispensing nozzle (N) facing the side of the tongs (51, 52). The upper bodies (51′, 52′) of the respective tongs (51, 52) are turned upwards so that the edges of the dispensing nozzle (N) lie against the lower bodies (511, 521) of the tongs (51, 52). The upper bodies (51′, 52′) are then returned to their original positions to secure the dispensing nozzle (N). The cap (2) is closed by forcing the lock (3) against the side of the base (1). The dosing button (68) is suitably positioned according to the desired dose. At this point, the external part of the dispensing nozzle, already held by the tongs (51, 52), is cut to a suitable depth by an external device that is specially designed for cutting.
The operator of the pasty food dispensing and dosing device should preferably hold the device with both hands and activate the device by moving the lever of the trigger (4) with the right hand, pulling it against herself/himself in a single movement, as far as the end of the course that is determined by the dosing button (68). The end of the dispensing nozzle (N) is pointed at the product to be prepared (a sandwich, for example), to dispense the product being dosed.
When the trigger lever is pulled, the following events take place concurrently:
When all of the food product has been dispensed, the cap (2) is opened and the now empty sachet (S) is removed to be discarded. The direction of the rotation of the ratchet (63) is reversed by the direction inverting device (64) so that the piston (8) is repositioned next to the back wall (12) of the base (1) and the device is ready for a new operation, with no cleaning necessary.
The present pasty food dispensing and dosing device therefore provides several advantages over the devices known in the prior art:
