Description

The invention relates to chew toys for dogs and methods for their manufacture [A01K 15/02, A01K 29/00, A23K 10/00, A23K 40/00].

From the prior art, a manufacturing method is known, implemented in a NATURAL CHEWING STICK FOR DOGS [http://china.org.ru/product/ru/10000003666014, web archive dated February 10, 2022], made of coffee tree, while chewing small fibers are separated from wood by a toy dog, which have an effect on the dog's teeth similar to that of dental floss. The technical solution aims to keep the dog's teeth clean and at the same time to enable the chewing function necessary for dogs.

Also known is a manufacturing method implemented in COFFEE WOOD STICKS [https://coffeewoodstick.tb.ru/page8, web archive dated 05/20/2022], made of coffee wood that does not contain artificial additives, components of animal origin and is not exposed to any or chemical treatment. The technical solution is aimed at reducing the traumatism of the oral cavity of dogs due to the decay of wood under the action of saliva into soft fibers.

The closest in technical essence is the manufacturing method implemented in the CHEWING WOODEN COFFEE STICK FOR DOGS [https://wallegro.ru/item/12177798248/DOGS-Gryzak-dla-psa-drewno-kawowca-Patyk-kawowy-M.html, web archive dated 05/11/2021], while the technical solution allows the dog to satisfy the need for chewing, reduce stress from excess energy, and remove tartar, while the use of coffee tree for the manufacture of chewing sticks avoids injuries to the dog's oral cavity, due to softening the outer layer of the sticks when moistened with dog saliva.

A common disadvantage of analogs and the prototype is the lack of fumigation and antiseptic impregnation of coffee tree wood in the technology for making sticks for dogs, which reduces the protective properties of the material and does not allow for the prevention of dental diseases in dogs.

The objective of the invention is to eliminate the disadvantages of the prototype.

The technical result of the invention is to increase the safety of the process of brushing teeth and the prevention of dental diseases in dogs.

The specified technical result is achieved due to the fact that the method of manufacturing a toy for dogs, including the collection of coffee tree wood, its drying, cutting the wood into sticks, mechanical and fumigation processing of sticks, characterized in that the drying of coffee tree wood is carried out until a wood moisture value of 8 to 22%, fumigation treatment of coffee tree sticks is carried out in a fumigation chamber at a temperature not lower than 120 ° C and for at least 20 hours, after mechanical and fumigation treatment, antiseptic treatment of wood sticks is carried out with antiseptic mixtures of at least four layers with the duration of intermediate drying between the application of layers is at least four hours at a relative humidity of not more than 80%.

Implementation of the invention.

Coffee wood is a natural by-product of harvesting coffee beans. After 20 years, the yield of coffee trees decreases, and in order to continue growing higher quality coffee beans, farmers often cut down trees to grow new ones. The wood of the coffee tree is strong and durable, while during the chewing process, under the influence of the dog's saliva, the outer layer of the wood softens with the separation of small fibers that are safe for the dog's mouth.

To implement the proposed method, coffee tree wood is harvested and dried, while in various embodiments, drying is used natural (in the open air, does not require compliance with temperature and humidity, is carried out within 3-6 months), chamber (drying chamber, duration 7 -8 days, temperature 30…70˚С, wood moisture content 10-18% is achieved, infrared (drying time 2…3.5 hours, drying uniformity is achieved), vacuum (at a pressure of 0.15…0.45 bar, temperature 50 ... 80˚С, drying time 3-8 days) or condensation (by means of condensation of warm moist air in a refrigeration unit, at a temperature of 40-50˚С, duration 10-20 days, wood moisture content of 8-10% is achieved). The required resulting moisture content of wood is 8…22%: at a moisture content of less than 8%, the wood will be overdried, lose its fibrous structure and be less attractive to the dog, since the dog easily gnaws it into pieces, and at a moisture value of more than 22%, the wood may become moldy, and when exposed to open air, it begins to naturally dry and crack.

Next, the wood is cut into sticks in accordance with the required dimensions. In various implementations, the sizes of the sticks are standardized according to the table values:

Size (dog weight) Length cm Width, cm XS (up to 3 kg) 12…12.5 1.5…2 S (3-5 kg) 13…14 2…2.7 M (6-10 kg) 16…18 2.8…3.7 L (11-20 kg) 19…20 3.8…4.5 XL (more than 21 kg) 21…22 4.6…5.5

or in other ways, based on the size of the dog: a dog that is too small will chew it into large pieces, which is safe, but reduces the life of the stick, and a stick that is too large is inconvenient for the dog. The values given in the table include, but are not limited to, ways to standardize stick sizes.

Then, using a grinder, the sticks are mechanically processed, turning sharp edges, after which fumigation treatment is performed, that is, a set of procedures aimed at protecting the product from insects, fungus, mold and other pathogenic microflora. In various embodiments, for fumigation treatment, special agents are used that contain methyl bromide (at a temperature in the fumigation chamber of at least 120 ° C and for at least 20 hours) and / or phosphine, for example, aluminum phosphide preparations - fostoxin, fostek, quickfos and magnesium phosphide - magtoxin.

Next, antiseptic treatment of wood sticks is carried out by exposing them to antiseptic agents that protect wood from microorganisms and beetles that affect it. In various embodiments, antiseptics based on water, oil, organic solvent, or a combination are used.

In one embodiment, at one or more points along the length of the stick, transverse through holes are made into which a rope (rope) made of natural fiber is threaded, which increases the number of options for using the stick by the dog when playing.

The method is implemented as follows.

In the manufacture of toys for dogs, the wood of the coffee tree was dried by natural drying to a moisture content of 15%, cut in accordance with the given table values in size XS, S, M, L, XL, the sticks were machined using a grinder to remove sharp areas and smooth the surfaces of the sticks were fumigated in a fumigation chamber with methyl bromide at a temperature of 120˚C for a total of 20 hours, after which with the QUICKPHOS 56GE insecticide for 4 days. Next, the antiseptic treatment of the sticks was carried out using a water-based antiseptic of the Pinotex type at a temperature of + 20 ...

The claimed technical result - improving the safety of the process of brushing teeth and preventing dental diseases in dogs - is achieved due to the fact that the drying of coffee tree wood is carried out until the moisture content of the wood is reached from 8 to 22%, which allows you to maintain the required structure of the wood fibers, avoids injury to the mouth. cavities of the dog from excessively dried fibers and avoid the formation of mold on it. Fumigation treatment of coffee tree sticks is carried out in a fumigation chamber at a temperature not lower than 120 ° C and for at least 20 hours: these parameters ensure guaranteed penetration of the fumigation substance into the wood fiber structure (these values were obtained experimentally, in the course of research). Antiseptic treatment of wood sticks with antiseptic mixtures is carried out in at least four layers with an intermediate drying time between applying layers of at least 4 hours at a relative air humidity of not more than 80% (these values were obtained experimentally, in the course of research). Antiseptic treatment protects wood from pathogenic microorganisms and insects that affect it. The specified number of treatment layers with the specified periods of intermediate drying ensure the penetration of the antiseptic agent into the structure of the wood fibers with a guaranteed possibility of maintaining the antiseptic properties of the toy throughout the entire period of its use. Thus, the increase in the safety of the process of brushing teeth and the prevention of dental diseases in dogs is ensured by a special mode of drying the wood of the coffee tree, fumigation and antiseptic treatment with the indicated technological modes. The use of the above features in combination eliminates the possibility of injury to the dog's oral cavity and guarantees the absence of mold, fungi, insects and microorganisms during the entire period of use of the toy.

In addition, when using the claimed method, the wood of the coffee tree does not break up into sharp chips and does not harm the soft tissues of the dog's oral cavity, while during the game the dog gnaws off small thin chips-fibers from the stick, which soften under the action of the dog's saliva and produce an effect similar to on the action of dental floss, removing all daily plaque.

An example of achieving a technical result.

In 2021-2022 the authors of the invention were made in accordance with the description of the proposed method, samples of toys for dogs.

The manufactured toys were tested on dogs of various breeds and sizes and confirmed the claimed technical result: there were no cases of damage to the soft tissues of the oral cavity of dogs, and the accompanying veterinary examinations confirmed a decrease in the number of cases of dental diseases over the specified period in dogs on which toys made by the proposed method were tested. way, in comparison with dogs, which were offered sticks for the game, made in accordance with the technologies implemented in analogues and the prototype.

At the same time, the declared positive characteristics of dog sticks were maintained throughout the entire period of their use, namely for 4-6 months.
