METHOD OF MANUFACTURING TOYS FOR DOG

DESCRIPTION OF THE INVENTION

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

A manufacturing method is known from the prior art, implemented in a NATURAL CHEW STICK FOR DOGS [http://china.org.ru/product/ru/10000003666014, web archive dated 02/10/2022], made of coffee wood, while chewing The dog toys separate small fibers from the wood, which have an effect on the dog’s teeth similar to the effect of dental floss. The technical solution is aimed at keeping the dog's teeth clean and at the same time enabling the chewing function necessary for dogs.

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

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

A common disadvantage of the analogues and the prototype is the absence in the manufacturing technology of dog sticks of the stages of fumigation and antiseptic impregnation of coffee tree wood, which reduces the protective properties of the material and does not allow the prevention of dental diseases in dogs.

The objective of the invention is to eliminate the shortcomings of the prototype. The technical result of the invention is to increase the safety of the teeth cleaning process and prevent dental diseases in dogs.

This technical result is achieved due to the fact that the method of manufacturing a toy for dogs, including collecting coffee tree wood, drying it, cutting the wood into sticks of the required size, mechanical and fumigation treatment of the sticks, characterized in that the drying of the coffee tree wood is carried out until the moisture content is reached wood from 8 to 22%, fumigation treatment of coffee tree sticks is carried out in a fumigation chamber at a temperature of 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 layer with a duration of intermediate drying between application of layers of at least four hours at a relative air humidity of no 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 declines, and in order to continue growing higher quality coffee beans, farmers often cut down trees to grow new ones. Coffee tree wood is strong and durable, and during the chewing process, under the influence of the dog's saliva, the outer layer of the wood softens, releasing small fibers that are safe for the dog's mouth.

To implement the proposed method, coffee tree wood is collected and dried, while in various implementations, drying is used natural (in the open air, does not require temperature and humidity, is carried out within 3-6 months), chamber drying (drying chamber, duration 7 -8 days, temperature 30...7О°С, wood moisture content reaches 10-18%), infrared (drying duration 2...3.5 hours, drying uniformity is achieved), vacuum (at a pressure of 0.15... 0.45 bar, temperature 5O...8O°C, drying duration 3-8 days) or condensation (using condensation of warm moist air in a refrigeration unit, at a temperature of 40-50°C, duration 10-20 days, humidity is achieved wood 8-10%). The required resulting moisture content of wood is 8...22%: with a moisture content of less than 8%, the wood will be overdried, lose its fibrous structure and will be less attractive to the dog, since the dog easily chews it into pieces, and with a moisture content of more than 22%, the wood may become moldy , and when exposed to open air, it naturally begins to dry out and crack.

либо другими способами, исходя из размеров собаки: слишком маленькую палочку собака будет разгрызать на крупные куски, что безопасно, но снижает срок службы палочки, а слишком большая палочка неудобна для собаки. Приведенные в таблице значения включают, но не ограничивают способы стандартизации размеров палочек.Next, the wood is cut into sticks in accordance with the required sizes. In various embodiments, the sizes of the sticks are standardized according to the table values:

or in other ways, based on the size of the dog: the dog will chew a stick that is too small 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 do not limit, ways to standardize stick sizes.

Next, using a grinding machine, the sticks are mechanically processed, grinding off the sharp edges, after which fumigation treatment is performed, that is, a set of procedures aimed at protecting the product from the effects of insects, fungi, mold and other pathogenic microflora. In various embodiments, special products containing methyl bromide (at a temperature in the fumigation chamber of at least 120°C and for at least 20 hours) and/or phosphine are used for fumigation treatment, for example, aluminum phosphide preparations - phostoxin, fastek, quickfos and magnesium phosphide - magtoxin.

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

In one of the implementation options, transverse through holes are made at one or several points along the length of the stick, into which the rope is threaded (rope), made of natural fiber, which increases the number of ways a dog can use the stick when playing.

The method is implemented as follows.

When making toys for dogs, coffee tree wood was dried by natural drying to a moisture content of 15%, cut in accordance with the given table values in sizes XS, S, M, L, XL, and the sticks were mechanically processed using a grinding machine to remove sharp areas and smooth them surfaces of the sticks, fumigation treatment was carried out in a fumigation chamber with methyl bromide at a temperature of 120°C for a total of 20 hours, followed by the QUICKPHOS 56GE insecticide for 4 days. Next, the sticks were antiseptically treated using a water-based antiseptic like Pinotex at a temperature of +20...28°C and a relative air humidity of no more than 80%, while the antiseptic was applied with a brush in 4 layers with an intermediate drying time of 4 hours.

The declared technical result - increasing 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 wood moisture content reaches from 8 to 22%, which makes it possible to maintain the required structure of the wood fibers and eliminates injury to the oral cavity. The dog's cavity 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 of not lower than 120°C and for at least 20 hours: these parameters ensure guaranteed penetration of the fumigation substance into the structure of the wood fibers (these values were obtained experimentally, during research). Antiseptic treatment of wood sticks with antiseptic mixtures is carried out in at least four layers with an intermediate drying time between application of layers of at least 4 hours at a relative air humidity of no more than 80% (these values were obtained experimentally during research). Antiseptic treatment protects wood from pathogenic microorganisms and insects that damage it. The specified number of treatment layers with the specified intermediate drying periods ensures penetration antiseptic agent into the structure of wood fibers with a guaranteed possibility of maintaining the antiseptic properties of the toy throughout the entire period of its use. Thus, increasing the safety of the teeth cleaning process and preventing dental diseases in dogs is ensured by a special drying regime for coffee tree wood, fumigation and antiseptic treatment with the specified technological regimes. The use of the mentioned signs together 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 coffee tree wood does not disintegrate into sharp splinters and does not harm the soft tissues of the dog’s oral cavity, while during play the dog bites off small thin splinters of fiber from the stick, which soften under the influence of the dog’s saliva and produce an effect similar 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 produced samples of toys for dogs in accordance with the description of the proposed method.

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

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