Description

DETAILED DESCRIPTION OF THE INVENTION The known process for making sandwich sandwiches consists of placing a food filling inside a tubular element, introducing the tubular element into a piece of bread, and then moving the tubular element out of the bread. It consists of simultaneous withdrawal and transfer of the stuffing contained in the tubular element into the pan.

The apparatus for carrying out this step comprises a stuffing-accommodating tubular element having a diameter smaller than the diameter of the bread slice to be stuffed and a length at least equal to the length of the bread slice; It is closed at its front end by a movable stop valve and, on the other hand, near its rear end by a piston-like element.

The present invention has unique uses, namely:
It is an object of the present invention to provide an advantageous concept of a device in which bread is stuffed and then dispensed, and in which it is not necessary to use ancillary equipment for this stuffing operation.

According to a basic feature of the invention, the front end of the tubular element is generally frustoconical or pyramid-shaped and has a slit which can be expanded under the pressure action of the food product when transferring the food product of the tubular element into the pan. and the rear end of the tubular element is provided with gripping means.

Since the conical shape of the front end of this device is appropriately selected to improve the flow of the bread contents, the tubular element can be easily inserted into the bread, especially when handling earless bread, and it can be easily passed through the street. A good cavity is obtained and also a food passage of suitable cross-section is ensured for the transfer of the food into the pan.

Due to the shape of the slit, the front end can open like a tulip or a valve.

According to another feature of the invention, the rear end of the tubular element, i.e. the end opposite to the end leading into the pan, is provided with an area of enlarged cross-section that includes a substantially annular portion. It has a gripping means constructed as follows.
This arrangement allows the user to firmly grasp the back of the tubular element when transferring the food into the pan, and prevents the back of the element from becoming greasy due to exudate. But it means you don't have to get your hands dirty.

the tubular element is covered at least over the area for insertion into the pan by a coating of synthetic material;
Advantageously, the end of the sheathing lying on the side of the tubular element is closed and the sheathing is movably fixed.

According to one preferred embodiment, the closed end of the sheath is snugly fitted to the front end of the tubular element.

The coating ensures the hygiene of the food during various operations and the retention of exudates during the entire operation and heating, in particular when the tubular element and the food it contains are placed in a hot tub and heated. Forms an airtight envelope.

Furthermore, the coating ensures that the frustoconical front end of the tubular element remains in a closed position and serves to avoid food escaping when stuffing the food into the tubular element.

According to one embodiment of the device, the tubular element has a piston with a longitudinal slit extending over its entire length and diametrically projecting fingers, the fingers extending through the slit of the tubular element. cross the
Its free end is also provided with a part forming a push lever.

In fact, when making Sanderutsch,
The tubular element is introduced into the bread slice until the push lever hits the rear end of the bread slice. The thumb of the hand holding the bread rests on the lever and prevents it from translating, while the other hand applies a pulling force to the rear end of the tubular element.

As a result, a relative displacement of the tubular element and the piston is possible due to the slits provided in the tubular element which serve as guideways for the fingers projecting from the piston.

Advantageously, the covering is fixed at one point on the tubular element near the open end thereof. This arrangement ensures that gases generated by the food when it is reheated escape, but first through the slits provided between the tubular element and the bonding points of the covering. You will have to run away.

Depending on the type of filling and the conditions of reheating of the tubular element, the coating may be fixed on the tubular element intermittently or non-intermittently by screwing, wedging, soldering or gluing. However, the important point is that by pulling, cutting, or tearing the covering, the association between these elements can be severed.

Furthermore, the tubular element has an externally projecting longitudinal rib into which the slit extends.
This rib prevents the coating from sticking tightly onto the tubular element and also creates a longitudinal flow path between the tubular element and the coating from which gases generated by the heat treatment can escape.

Advantageously, the slit has successively narrower areas. These narrowed areas serve as a stop that prevents the slit from closing under the pressure of the coating and ensures that there is space for gas to escape.

According to another embodiment of the device, a wire or similar other tensioning element is fixed on the front side of the piston closing the rear end of the tubular element;
It extends the entire length of the tubular element and extends beyond its front end.

In practice, in such a case, the tubular element is inserted into the pan until it protrudes from the front end of the tubular element, whereby the user grasps the end of the tensioning element and It becomes possible to prevent movement of the piston when pulling the tubular element out of the pan.

In any case, the invention will be better understood from the following description, made with reference to the accompanying drawings, which show, by way of example, several embodiments of the device. however,
It goes without saying that these examples do not limit the scope of the invention.

The device shown in FIGS. 1 to 4 includes a tubular element 2 for containing a food product 3 forming the filling of a bread slice 4. The device shown in FIGS. The front end 5 of this tubular element
is approximately frustoconical in shape and has longitudinal and transverse slits 6 and 7 which, under normal conditions, keep their front ends conical, but do not allow the food 3 stored inside the element 2 to When pressure is applied to
This action allows the front end to be opened.

As shown, the rear end of the tubular element 2 is flared and provided with a ring 8 . Furthermore, the tubular element is provided with a longitudinal slit 9 extending over its entire length and leading into an outwardly projecting rib 11.

As shown in FIG. 3, the inside of the slit 9 is not constant, but has a constant number of narrowed areas 9a.
, which serve to prevent the slit from closing in the wider area when its edge is supported. The rear end of this tubular element is closed by a piston 10,
The piston consists of two parallel discs 12 connected by a crosspiece (spacer) 13, from which fingers 14 project diametrically across the slit 9. Its free end is also provided with a push lever-like part 15.

Furthermore, the tubular element has a covering 16 of soft synthetic material up to the level of the push lever 15 of the piston 10.
The leading end of the covering is closed and snug against said end, and the open trailing end is wrapped, for example with adhesive, over the tubular element. are fixed in dots.

In reality, the food product 3 is conditioned inside the tubular element after applying the coating 16, but the coating remains in place throughout the various manipulation and reheating operations and the introduction of the tubular element into the pan. It is only pulled out of the tubular element just before it is removed.

As shown in FIG. 4, the tubular element is inserted into the pan until the push lever 15 abuts the rear end of the pan. Here, the user
Place your finger on the push lever, hold the pan with the thumb of your hand, and use your other hand to apply a pulling motion to ring 8, which will pull the tubular element back out of the pan and release the food into the pan. can be moved to.

FIG. 5 shows a different embodiment of this device, in which the tubular element is not slitted and in which a tension element, such as a wire 17, is provided on the front side of the piston 10a. is fixed, and the wire extends the entire length of the tubular element and exits beyond its front end. The piston 10a is held by a ratchet mechanism through which a rib 18 projects near the rear end on the inner surface of the tubular element through a rear passage.

In the embodiment shown in FIG.
assumes a lateral position rather than an axial position, but this ring may consist of a fixed tongue 8a, as shown in the left part of the figure, or with a fixed tongue 8a, as shown in the left part of the figure. As shown in the section, it consists of a movable tongue 8b. In these cases, the tubular element is inserted into the bread slice 4 until the front end of the tubular element extends beyond the bread slice. here,
