The device for storing and applying the preparation (variants).

The useful model refers to the devices for storing various preparations and applying them to the processing surface and can be used in various fields, for example, as a writing tool or in medicine and cosmetics for applying medicines, aseptic and fragrant agents, etc. preparations to the epidermis for medicinal, prophylactic and cosmetic purposes.

A device for storing and applying a preparation is known, which contains a body in the cavity of which there is a fragile capsule with the preparation, one end of the body being hermetically sealed and the other end being open. On the hermetically sealed end of the body there is a soft tip for collecting liquid, and on the other end there is a porous tip for applying the preparation to the processing surface (see patent USA Jfs 6283933, �Mgr;&Pgr;&Kgr; A61M 35/00, published 04.09.2001).
The disadvantage of the known device is that the processing of important surfaces, especially those in hard-to-reach places, is made difficult by the porous tip with a small cross-section. In addition, the processing of important surfaces using the known device is difficult and can lead to poor quality processing of the surface due to the presence of unprocessed areas.

A device for storing and applying the preparation is known, which contains a hollow body and a porous supply element, with one part of the supply element being located in the cavity of the body, the other part of the

body and a part protrudes from the body. In addition, the device includes a storage for the preparation which is located in the cavity of the body (see the application of Japan Ns 200034388, &Mgr;&Pgr;&Kgr;&Bgr;43&Kgr; 8/02, published 12.12.2000).

When using the known device, the processing of large surfaces, especially in hard-to-reach places, is difficult because the application of the preparation is carried out using a thin core, while the surface of the core that comes into contact with the processing surface is small and corresponds to the size of the opening in the device. The porous core in the known device leaves a trace that looks like a line when it comes into contact with the processing surface, and in order to process large areas with the preparation, several lines must be applied to the processing surface, which increases the probability of untreated areas and reduces the quality of processing.

The closest technical solution to the one applied for is a device for storing and applying the preparation, which contains a hollow body and a porous supply element, with one part of the supply element being located in the cavity of the body, the other part being fixed by the body and the other part protruding from the body. In addition, the device contains a storage for the preparation, which is located in the cavity of the body (see the application of Germany Jfe 8201867, �Mgr;&Pgr;&Kgr; A 45D 34/04, published 19.07.1984).
With the help of the mentioned device, the surgical processing of surfaces in hard-to-reach places with a large area is difficult, because the application of the preparation is carried out using a thin supply core, the geometric dimensions of which are limited by the diameter of the opening in the device, and when applying the preparation to a large surface, it is necessary to apply several lines, which can lead to poor quality processing due to the presence of untreated areas.

The task of this useful model is to create a device for storing and applying the preparation, which is more convenient in use and increases the quality of surface processing.

The technical result achieved by solving the problem is the reduction of the surface processing time by shortening the contact time of the device with the processing surface, as well as the continuous coverage of the processing surface with the preparation.
The stated object is also achieved in that in the device for storing and applying the preparation, which contains the hollow body and the porous supply element, the first part of the supply element is located in the cavity of the body, the second part is fixed by the body and the third part protrudes outwards from the body, while the first and second parts of the supply element located in the body are coaxial with the longitudinal axis of the body, according to the useful model, and the part of the supply element protruding outwards from the body is inclined at an angle α to the longitudinal axis of the body, wherein the ratio between the cross-sectional areas of the part of the supply element protruding outwards from the body to the part of the supply element located in the body is not less than 2.5:1.

In this case, the value of the angle of inclination α for the part of the porous element protruding from the body to the outside is within the limits 0°< α < 90° and the linear dimension of the supplying element part protruding from the body to the outside along its longitudinal axis is not longer than the largest linear dimension in the direction perpendicular to its longitudinal axis.

The claimed set of features ensures that in the claimed variants of the device for storing and applying the preparation, when used, a larger area is treated in one unit of time, which reduces the time spent treating the surface, including the time of direct contact of the device with, for example, the damaged surface to be treated,

·

and also increases the convenience of using them. The above-mentioned ratio between the cross-sectional areas of the parts of the supply core is necessary for uninterrupted supply of the preparation to the surface of the supply core and its application to the surface to be treated. The design of the supply core according to the proposed technical solution makes it possible to exclude untreated areas on the surface, because during one touch the significant surface is treated and with the next touch it is possible to treat the surface immediately adjacent to the previously treated surface, and the design of the parts of the supply core with the proposed ratio of cross-sectional areas ensures repeated supply of the preparation to the surface of the supply core in the time between touches of the surface to be treated. In addition, it increases the convenience of self-treatment of hard-to-reach areas of the human body, for example, in the area of the cervical vertebrae, armpits, groin, etc., especially in home and travel conditions.

The claimed useful model is explained by the following symbols, where in Fig.1 and 2 the examples of the design of the device for storing and applying the preparation after the longitudinal cut are shown, in Fig.3 the porous feeding core in the first variant after the longitudinal cut and in Fig.4 the porous feeding core in the first variant after the bottom view.

The positions on the figures indicate the following: 1 - the body; 2 - the part of the supplying element located in the cavity of the body (l); 3 - the part of the supplying element fixed by the body (l); 4 - the part of the supplying element protruding from the body (l); 5 - the storage of the preparation.

The device for storing and applying the preparation contains the hollow body (l) and the porous supply element, in which the first part (2) is located in the cavity of the body (l), the second part (3) is fixed by the body (l) and the third part (4) protrudes outward from the body (l), the first (2) and second (3) parts of the supply element located in the body (l) are coaxial with the longitudinal axis O - O of the body (l) (Fig.l).

The part (4) of the porous supply element which projects outward from the body (l) is inclined to the longitudinal axis O - O of the body (l), the size of the inclination angle α being within the limits 0° < α < 90° (Fig.l).
The ratio between the cross-sectional areas of the part (4) of the supply element which projects outwards from the body (l) to the part (2) of the supply element which is located in the cavity of the body (l) is not less than 2.5:1 (Fig.l).

Furthermore, the linear dimension L 1 of the supply element part (4) protruding outward from the body (l) along its longitudinal axis Oi - Oi is not longer than the largest linear dimension L 2 in the direction perpendicular to the longitudinal axis Oi - Oi of the supply element part (4) protruding outward from the body (l) (Fig. 2 and 3).

In the cavity of the body (l) the porous reservoir (5) for the preparation is built in and the part (2) of the supplying element which is located in the cavity of the body (l) is in contact with the reservoir (5) (Fig.l).

The numerical values of the ratio between the cross-sectional areas of the part (4) of the feeding element protruding from the body to the part (2) of the feeding element located in the cavity of the body are empirically determined as the optimal ratio that ensures sufficient and necessary application of the preparation to the treated surface during one contact.

The numerical values for the ratio are determined by the need to feed the preparation along the axis of the porous feeding element at a constant or increasing speed in the direction of delivery from the

Part (2) of the feeding element which is in contact with the reservoir (5) of the preparation, through the part (3) of the feeding element which is fixed by the body (l), to the part (4) of the feeding element which projects outwards from the body (l), and further to the processing surface, during the interval between the contacts of the feeding element with the processing surface.

The maximum area of the cross-section for the part (4) of the supply element which projects outwards from the body (l) can only be limited by the dimensions and shape of the body (l).

The design of the part (4) of the supply element protruding from the body (l) with a larger linear dimension L γ in the direction coincident with the longitudinal axis O - O of the body (l) than its linear dimension L2 in the direction perpendicular to the longitudinal axis O - O of the body (l) leads to the need to increase the amount of preparation in order to ensure saturation of the entire volume of the part (4) of the supply element protruding from the body (l). This in turn leads to an increase in the external dimensions of the body (l).

The part (4) of the supply element that protrudes from the body (1) to the outside can be made of a dense or deformable porous material. For example, glass fiber made of polyolefin or porous plastic can be used as a dense porous material, and for example, foam or felt can be used as a deformable porous material.

If the part (4) of the supply core, which protrudes from the body (l) to the outside, is made of a dense porous material, then it can be used, for example, as an application (plaster) which is applied to the treated surface of the body as a carrier of a preparation acting on the organism.

If the part (4) of the supply element, which protrudes from the body (l) to the outside, is made of the deforming porous material, then it can be used, for example, or as the application (plaster) for transferring the preparation to the processing surface, or as the swab for absorbing from the

t ·

processing surface of the liquid. In the first case, the porous reservoir of the device is impregnated with the necessary preparation, and in the second case, the porous reservoir is not impregnated with the preparation and serves as the receiver for the absorbed liquid.

To reduce evaporation and to facilitate storage and transportation, the device for storing and applying the preparation in all versions is equipped with a hermetic cap (see Fig.

is not shown).

The device for storing and applying the preparation is assembled as follows.

Example 1. The porous reservoir (5) is saturated with the necessary preparation and placed in the cavity of the body (l) coaxially with its longitudinal axis O - O. The porous supply element is placed in the body (l), with the part (2) of the element being in contact with the reservoir (5), the part (3) of the element being fixed by the body (l), and the part (4) protruding outwards.

The device works as follows.

The preparation, which is located in the porous reservoir (5) mounted coaxially with the longitudinal axis of the body (l), moves to the processing surface along the longitudinal axis O - O of the body (l) through the feeding element. The preparation enters the part (2) of the feeding element, then the preparation enters the part (3) of the feeding element fixed by the body (l), then enters the part (4) protruding from the body (l) to the outside and further onto the processing surface.

The mentioned method of movement of the liquid preparation is due to the following.

According to the theory of the outflow of liquid through porous materials, the physical &mdash; chemical principles of moistening and deliquescing and the general theory of filtration, from the porous body with larger volume during

In the presence of the pressing air pressure, the preparation will flow at a certain speed towards the porous body with a smaller volume, if these bodies are connected. The manufacture of porous bodies with the predominant orientation of the pores plays an important role. The physical and chemical parameters, the design of the porous reservoir and the supply element are selected empirically depending on the properties of the preparation and the purpose of the device (see P. Kojijihh3. TeieHHa mnmocreH qepe3 nopHCTwe MaTepHajibi. - M.: 1964; B./L CyMM, K)B. &Ggr;&ogr;&rgr;&igr;&ogr;&EEgr;&Ogr;&Bgr;. &Phi;&eegr;3&eegr;&kgr;&ogr; - XHMHiecKHe ocHOBBi CMa^HBaHiW &eegr; pacTeicamui. - M.: Xhmhh, 1976; Pa3BHTne HccjieflOBaHHH no Teopnn 4>HJi&Tpain«i β CCCP. - M.: Hayica, 1969). In this way the preparation saturates the porous supplying element through its entire volume.

The attractive forces acting between the molecules of the pores in the solid element body and the preparation force the preparation molecules to rise along the pore wall, which leads to bending of the section of the preparation surface adjacent to the pore wall. This creates negative (capillary) pressure, which at each point on the bent surface exactly compensates for the pressure caused by the rise in the liquid level. At the same time, the mutual attraction of the liquid molecules (cohesion) is weaker than the attraction of the liquid molecules to the molecules of the surface of the solid body (adhesion), which causes the movement of the preparation along the pores of the supply element in the direction of the preparation release until the parts of the supply element located in the body and the part of the element protruding above them are completely saturated. The devices for storing and applying the preparation of the proposed design ensure the movement of the preparation also in the direction perpendicular to the axis of the porous supply core, until the peripheral sections of the protruding part of the core are completely saturated.

The preparation enters the protruding part of the supplying element until the saturation by it of all communicating pores of the porous element is accomplished.

In this way, all freely communicating pores of the supplying element are filled with the preparation, the air that was in the free pores is forced out through the preparation, the capillary pressure in the porous element is equalized and the preparation will not flow out of the protruding part of the porous element on its own initiative.

During processing, part of the preparation will flow out onto the processing surface. To maintain the capillary pressure at a balanced level, a new portion of the preparation will enter the free volume of the porous body.

The use of devices for storing and applying the preparation allows the surface to be treated with a reduction in processing time and with full coverage of the processing area, thereby improving the quality of processing. In addition, the use of devices of the above-described designs increases the convenience of independently treating hard-to-reach areas of the human body, for example, the cervical spine, armpits, groin, etc., especially in extreme domestic and travel conditions.
