Description

Purpose and scope

The utility model relates to devices for cooking food used in everyday life, in the country, or at picnics for heat treatment of food on charcoal or open fire, mainly in the open air, in particular to auxiliary equipment - skewers, including skewers, skewers, forks fondue, and can be used to isolate and protect the tip of the tip of such a spit.

Prior art

Caps of various types and purposes are widely known. For example, a protective cap for knitting needles is known (page 13, Article No. 333 / S, Product Catalog, ver. 9.0. Clover Mfg Co., Ltd .; https://www.clover-mfg.com/ru/product/ 4/206). It is made in the form of a cone with rounded edges and a cylindrical recess in the center of the base, designed to prevent the hinges from slipping.

However, this cap is not intended for use in cooking devices, much less used over open fires or coals. Its shape and size, as well as the material from which it is made, prevent its use for other purposes. This cap does not provide a secure fit on the tip, because to a large extent designed to hold the loops on the knitting needle. Due to its small dimensions in length, with the chosen shape of the cap in the form of a cone, it is impossible to carry out any manipulations with the spoke, holding it by the cap put on the tip. The cap slides off the tip of the spoke when manipulated using the cap as a holder or handle.

Also known are cases for storing skewers, for example, skewers, with a complete set of skewers inside the case (https://shampura.com/product/nabor-shampurov-premium-variant-5/) or only their open end in the area of the tip (https : //shampura.com/product/nabor-shampurov-orel-variant-5/).

However, the design of these devices, ensuring the protection of surrounding objects during storage of a set of skewers as a whole, does not imply the possibility of their use as an individual protective device that insulates the tip of the skewer tip, both during storage and during its direct use when cooking on charcoal or on an open fire, when eating food directly from the skewer, as well as when transporting the skewers to the storage or table setting.

Caps for insulating the outer end of the skewer, including skewers, skewers, etc. prior art skewer devices were not found during the search.

Nevertheless, this technical problem is still relevant.

The essence of the utility model.

The technical problem solved by the claimed utility model is to provide a simple auxiliary device that protects users from injury and surrounding objects from damage by the outer end of the rotisserie-type food preparation device, while increasing the ease of use of the rotisserie-type food preparation device.

The technical result consists in increasing the operational characteristics of a device for cooking food such as a skewer, including skewers, skewers, fondue forks by ensuring the isolation of the tip of the outer end of this device and the accompanying expansion of functionality.

The linear dimensions of the channel in its cross-section are preferably made with the possibility of tightly enclosing the trochanter in the area adjacent to the open inlet of the channel at the place where the cap is mounted on the spit. Moreover, in one of the embodiments, the maximum linear size of the channel in the cross section in the area adjacent to the open entrance of the channel does not exceed the linear size of the trochanter tip adjacent to the channel in its cross section by more than 3 mm.

In a preferred embodiment, the channel on the side of the blind base is additionally provided with a stopping tapering recess made to prevent the tip of the trochanter from contacting the blind base of the channel.

In this case, in possible embodiments of the claimed utility model, the body can be made in the form of a body of revolution, a prism, a figured shape, the side surface of which is formed by the curvature of surface elements with different shapes.

In another possible embodiment, the body of the insulating cap can be additionally provided with a retainer designed to allow fixing the position of the cap on the trochanter shaft in the region of the tip. Moreover, the latch can be equipped with at least one magnetic element.

In another embodiment of the claimed invention, the channel of the recess of the retainer can be made with a narrowing from the external open inlet to the blind base.

An embodiment is also possible, according to which the housing can be additionally provided with a handle, which in one embodiment can be detachable.

According to the claimed invention, the body of the insulating cap according to any of the possible embodiments can be made of polymeric materials, for example, food grade silicone.

Embodiments are also possible, according to which the cap body can be made of composite materials, synthetic heat-resistant materials, including those with heat resistance in the upper temperature range from + 70 ° C to + 200 ° C, while maintaining thermal insulation properties, as well as wood, including with refractory impregnation.

The embodiment presented in the illustrative materials is one of the possible embodiments of the claimed utility model and cannot serve as a basis for its limitation.

Feasibility of the utility model.

The insulating cap 1 (Fig. 1; 2) for the tip of the skewers, including the skewers 2 (Fig. 2), according to the illustrated embodiment, is made, for example, of food-grade silicone, in the shape of a body of revolution, with the formation of a lateral surface close to cylindrical. At the same time, the shape of the cap can be complex, for example, with a flat outer base and a lateral surface made as a result of curved conjugation of flat and convex surfaces. It is also possible to manufacture a cap body of a prismatic shape, with a number of edges, convenient for storing skewers in the storage area and for practical use during the preparation of a product strung on a spit, including a skewer. More complex forms of the cap body, combining both flat sections and curved convex and concave sections of the outer surface, providing a convenient grip of the cap during its operation, are also possible when implementing the claimed utility model. In this case, according to the claimed utility model, the body of the cap, in any case, is provided with a recess, the channel 3 of which is made with an open inlet 4 on the outside, and a blind base 5 on the other side, located inside the body. The shape of the channel preferably repeats the shape of the trochanter shaft, however, it can also be made in the form of a cylindrical, prismatic surface, as well as a surface that forms a channel with a truncation towards a blind base. In this case, according to the embodiment shown in the drawings, Figs. 1 and 2, the linear dimensions of the channel cross-section are preferably made with the possibility of tightly covering the trochanter in the region adjacent to the open channel entrance at the place of installation on the spit, i.e., its width and the height, in this case, is made not exceeding the maximum linear dimensions, width and thickness, of the tip of the spit rod in cross section. At the same time, for the convenience of installing the cap on the tip of the trochanter, in the area of the open hole of the channel, in one of the possible embodiments, the linear dimensions of the channel in its cross-section do not exceed the corresponding dimensions of the adjacent surfaces of the trochanter at the place where the cap is installed on it by more than 3 mm. In addition, the length of the canal is greater than the width as well as the height of the canal, but less than the length of the cap body. This channel shape makes it possible to hold the cap on the trochanter shaft in the area of the tip due to the frictional forces generated between the mating surfaces. In this case, when the body of the cap is made of food-grade silicone, it is possible to make the channel of the recess narrowed relative to the adjacent surface of the tip of the trochanter. For example, in one embodiment, in width, and possibly also in height, in another embodiment, this allows the cap to be fitted with an interference fit, creating additional locking forces to hold the cap in place.

To enhance the fixation of the cap on the trochanter shaft, the cap can be additionally equipped with fixing elements (fixation), for example, in the form of placing at least one magnetic element in the alignment of the open inlet, in the channel cavity, in the zone of its blind base. This embodiment of the fixation is preferred for caps made of materials with a higher rigidity than food grade silicone, for example, made of composite materials, synthetic heat-resistant materials, and wood, for example, with a refractory impregnation. The magnetic interaction of the metal (made of steel) tip of the trochanter with the magnetic element ensures reliable fixation of the tip in the cavity of the channel of the recess of the cap.

In this case, the material used for the manufacture of the cap body must have low thermal conductivity to ensure the preservation of the physicochemical properties of the cap material and its functionality, which consists in ensuring the insulation of the spit tip and thermal insulation of the spit shaft (skewer, skewer) in the area of the cap placement, as well as performing protective functions for users and surrounding objects. According to the claimed utility model, low thermal conductivity is understood as the thermal conductivity of a material whose thermal conductivity coefficient is lower than that of (food grade) stainless steel, from which most metal skewers are made, including skewers, skewers, etc.

The requirements for the temperature resistance of the materials used in the manufacture of insulating caps, according to the declared utility model, are determined by the specifics of their operation on spits during cooking on coals, over an open fire. The material of the cap must perform insulating functions, both in the storage mode at normal, room temperature, and in the operation mode when the spit rod is heated on coals, on an open fire. At the same time, given the purpose of the skewers as auxiliary devices for cooking, the material for the manufacture of caps must be approved for use in food production to ensure the safety of its use.

Based on the foregoing, for example, heat-resistant materials in the temperature range for the upper heating value from + 70 ° C to + 200 ° C can be selected as the materials of the cap, while maintaining the thermal insulation properties. The choice of the specified range of insulation temperatures is due to the following. The optimum temperature range, for example, for roasting meat, is 150-200 ° C on its surface. Accordingly, the skewer, as a special case of the skewer, in the working area of the barbecue heats up no higher than + 200 ° C degrees, while at the edges of the skewer that do not enter the working area of the barbecue, the temperature is much lower and depends on the metal from which the skewer (skewer) is made, and also the cooking conditions (weather conditions, heating intensity, proximity to an open fire or coals, etc.) and may not exceed + 70 ° C. Thus, based on the conditions of minimal heating of the end of the skewer in the area of the cap placement and possible operating conditions at higher temperatures, it is possible to determine the above requirements for the heat resistance of the cap materials, which are sufficient to ensure the functional properties of the cap while maintaining the operational, including the heat-insulating properties of the cap.

However, along with the requirements for the heat resistance of the cap material, which to a greater extent determine the chemical resistance of the material to temperature influences, for the comfortable use of the insulating cap when choosing a material, the thermal conductivity index is important, which determines the stability of the physical properties of the material under temperature exposure. Obviously, the efficiency of the cap, from the point of view of ensuring the specified heat-insulating properties of the cap, will increase if the thermal conductivity of the material from which the cap is made is lower than the thermal conductivity of the material from which the skewer is made (skewer, skewer). Since, for the manufacture of skewers, skewers, skewers, etc. mainly use low-carbon steel, stainless steel, as well as aluminum, and the lowest thermal conductivity among these materials belongs to stainless steel (15-19W / (m K)), respectively, the thermal conductivity of the material from which the cap is made should not be higher than the indicated values, and it is preferable to have a significantly lower thermal conductivity inherent in heat-insulating materials used for thermal insulation of equipment, for example, when cooking products over an open fire.

The cap can also be made, for example, of wood with a refractory impregnation, since this material has all the above physicochemical properties that characterize the thermal insulation properties of the cap material, which determine its functionality.

Taking into account the possibility of making the spit rod with a sharp tip end, in order to avoid puncture and cut the material of the cap body, for example. made of food-grade silicone, other acceptable material, from the side of the blind base, the channel can be provided with an additional deepening made narrowed, with the possibility of forming a gap between the tip of the trochanter tip and the base of the narrowed deepening. Thus, the possibility of a destructive effect of the pointed tip of the trochanter tip on the body elements is excluded, while maintaining and increasing the performance characteristics of the cap.

Placing the cap on the tip of the skewer also allows it to be used as an additional handle, providing access to the control of the preparation process of the skewered product from both sides of the skewer, as well as providing a more comfortable and safe process for others to consume the prepared product directly from the skewer (skewer, skewer), which can be safe for the user to hold with both hands. The outer surface of the cap can be used as a handle. At the same time, the handle can be made from the side of the outer free end of the cap, for example, as a result of the formation of the annular grip 6 (Fig. 1), or another shape of the grip that is convenient for manual control.

Since in the practical use of the cap in the cooking process, for example, when using skewers, it is necessary to take into account the length of the skewer and the width of the barbecue. For the convenience of manipulating skewers when frying meat, it is recommended that they overlap the width of the barbecue by 20 cm, respectively, the margin on each side, with the standard length of the skewers, is at least 10 cm, given that the most common width of the barbecue is 25-40 cm, and the most the common length of skewers for barbecues of this size is 45-60 cm. Experimentally for skewers, such as skewers, it has been established that the most optimal length of the cap channel for this type of skewers, with sizes from 45-60 cm, lies in the range of 3.5-5 cm, and for skewers with sizes from 60-100 cm lies in the range of 5-9 cm. In this case, the canal ensures reliable fixation of the trochanter in the canal cavity, providing freedom of manipulation of the trochanter, including from the side of the cap. Since the total length of the cap exceeds the length of the canal, for the specified range of values of the canal, in accordance with which the length of the cap body is more than 3.5 cm, it provides a convenient grip of the trochanter from the side of the cap and the general convenience of using the outer surface of the tip as an additional handle. At the same time, compliance with the optimal, from the point of view of the safety of cooking food on an open fire or coal, distance between the wall of the barbecue and the insulating cap of at least 5 cm is ensured.

The insulating cap for the tip of the skewers is used as follows.

An insulating cap 1 is installed on the spit rod 2. For this, the insulating cap is put on the outer end of the tip of the rod 2 through the channel 3 of the recess. The end of the tip of the rod 2 rests against the bore of the channel 3 of the recess from the side of the open hole. Under the action of the load, the material of the insulating cap, for example, made of food grade silicone, stretches, the diameter of the recess 3 increases. The rod 2 is immersed in the recess 3. The insulating cap is held on the rod 2 due to the friction forces caused by the mating surfaces and elastic tensile-compression forces arising due to the desire of the cap material to return the original shape of the channel.

The cap is not removed from the skewer (skewer, skewer, etc.) during the preparation of the skewered product, eating food directly from the skewer (skewer, skewer, etc.), its transportation and storage. Since the cap is removable, the cap can be removed from the tip of the spit at any time, however, functionally, the cap can be removed only when stringing the product onto the spit (skewer, skewer, etc.), removing it from the spit (skewer, skewer etc.) and maintenance of the spit.

The use of an insulating cap for the tip of the spit improves the performance of the spit-type food preparation device by isolating the tip of the spit, providing both mechanical protection and thermal insulation of the tip of the spit, thereby increasing the protection of users from injury from the outer end of the tip of the rods of the spit, as well as protection of surrounding objects from damage, with a simultaneous expansion of the functionality of the use of the spit during its operation and during storage and transportation.
