SK25894A3 - Enamel applicator with doser plug - Google Patents

Abstract

The plug is intended to be coupled to a container which holds an enamel for nails or the like. The application may be effected by actuating sideways a push-button (15) or by pressing axially an annular push-button (21). By acting on the push-button (15, 21), a cannula (9) is displaced axially and acts upon the plunger of the pumping device (4) which is part of or is mounted on the mouth of the container holding the enamel. When releasing the push-button, the product is ejected to the bristles (13) of a brush-type applicator which emerges from a trunco-conical nozzle (19) integral with the body. The trunco-conical nozzle (19) is sealingly closed by means of a threaded cap (20) and carries inside an obturating bell which is adapted to the conical periphery of the nozzle and which is spring-biased (30). <IMAGE>

Description

Announces techniques

The solution described in this application relates, as is evident from the title, to a paint applicator with a dispensing stopper that is deliberately connected to a container filled with nail varnish or the like. The stopper is provided with a closure firmly closing the container and with bristles through which the product located inside the container passes so that the product cannot escape.

The lacquer to be used is obtained by means of a pumping element which is triggered externally by a button.

The use of the product during application is very simple. Just remove the stopper and use, after refilling the paint, a brush whose sleeve serves as a holder.

BACKGROUND OF THE INVENTION

A number of conventional lacquer containers are provided with a cap that is connected to a paint brush immersed in the lacquer fill.

The Applicant of the present invention also has a patent application number P-9100612 relating to a nail varnish applicator comprising a container containing a varnish. This device is relatively complex and consists of a neck and a lid with elements sealing the container by means of a lid, inside of which there is a brush for automatic application of the lacquer in single portions of the product captured on the surface of the brush. Said operation is performed during the movement of the finger which is inserted into the opening in the container. This makes it possible to obtain more than two layers of lacquer during the application of the lacquer during finger-painting.

SUMMARY OF THE INVENTION

The drawbacks of the current devices are largely overcome by the varnish applicator with the dispensing plug of the present invention. In essence, the neck of the lacquer reservoir is provided with either threaded components or elements for simply exerting a compressive force, also permitting longitudinal relative relative displacement of the two bodies and the presence of elements preventing the container from being accidentally opened.

The pump element is characterized by a cylindrical sleeve with a smooth surface portion and a remainder portion provided with a plurality of slots or openings through which the product enters the container or container. The piston of the pumping element is provided with a spring in such a way that the force exerted against the spring by the cannula protruding its bevelled part from the sleeve and located in the slots of the support member of the pumping element returns the latter to its original position.

The pump element and the container neck are located inside the dispenser cap housing or package. The free end is provided with an external thread for connection to the conical nozzle through which the application brush passes with the product delivered after pressing the button.

The product application brush is closed by a cap or cap extending through the cone nozzle, thereby preventing the product that is sucked in the application brush bristles from drying.

In the lid there is also a component in the form of a sealing element intended to firmly close the application brush. This component can move in the direction of the longitudinal axis, depending on the spring force. Said spring exerts a compressive force in the direction of the cap so that the sealing element is pressed against the conical surface of the cone nozzle.

The applicator brush is connected to the end of the cannula through which the product flows after pressing the button.

For a better understanding of the present invention, its form and interconnection, drawings are given in which some possible actual embodiments are shown, but are not limited to the claims.

DETAILED DESCRIPTION OF THE INVENTION

It will be apparent from the accompanying drawings that the lacquer applicator with the dispensing plug of the present invention may be in one case shown in FIG. 1 and 2, formed by a cylindrical bushing 1 which is connected to the neck 2 of the thread of the paint container 2. The pump element 4 is inserted into the neck 2 of the cartridge 2 so that it is immersed in the product. The pump element 4 is formed by a sleeve 5 which is smooth at one end and is covered by a plurality of axial slots 6 inside which a piston (not shown) may be accommodated to assist in springing the spring to press it toward the widened end 7 sleeves 5.

In the longitudinal bore 8 of the pump element 4, the cannula 9 is partially inserted, which actuates the piston. The other end of the cannula 9 is formed as a cover 10 from which protrudes an axial rigid channel 11, which is telescopically inserted into the extension tube 12, the other end of which is connected to the bristle roots 13 of the product application brush.

The cylindrical housing 1 is provided on the side with a viewing window 14 in which a button 15 for actuating the pumping element 4 is located. The button 15 has a U-shaped cross-section whose sides have a substantially triangular cross-section. Their sharp apex is provided with a pair of arc bolts 16 which allow rotation and at the same time connection to the inner axis of the body (not shown). At opposite ends, such as a sharp apex, there are arcuate flanks that allow the cannula 9 to move and move by the stop 17. The movement of the stop 17 is realized by contacting the face of the stop 17 with the convex side surface. The passing tube nozzle 12 is constructed as shown in FIG. Second

The free end of the cylindrical sleeve 1 is provided with an external thread for connecting a conical nozzle 19 with an axial opening through which the product application bristles 13 pass, as shown in FIG. First

The cone nozzle 19, as well as the bristles 13, are completely closed by means of the closure 20. This closure 20 has an internal thread for connection to the thread on the conical nozzle 19 and the interior of this closure 20 is provided with another cap 29 with spring 30 which presses it into the closed position as shown in FIG. 4th

With this arrangement, the stopper 12 and thus the cannula 9 can be pushed with the finger 15 by means of a finger. Thus, the product is transported from the pump element 4 in batches. After pressing the button 15, the product is conveyed by the piston of the pumping element 4 through the cannula 9, the rigid channel 11 and the extension tube 12, so that the bristles 13 are soaked so that the nail varnish can be applied.

In FIG. 3 shows another possible specific embodiment where. the actuation button of the pump element 4 is cylindrical in shape and in the present case is indicated by the reference numeral 21. The cylindrical button 21 is arranged in the direction of the arrow shown and can have an axially positioned cannula 9 so as to pressurize the piston. In this case, the conical nozzle 19 and the closure 20 do not extend beyond the cylindrical button 21.

It will also be appreciated that the cylindrical button 21 is attached in the case of a small length given by the neck of the cartridge 22 for axial movement, i. a relative axial displacement between said container and the cartridge 22 and this cylindrical button 21. This is made possible by elements assembled in order to exclude some elements. By screwing the closure 20 to the cone nozzle 19, the product is transported in batches sequentially to the bristles 13 and directly to the closure 20. If the closure 20 is later released, the bristles 13 are always soaked in the product and ready for application.

In FIG. 4 shows an exemplary embodiment that is; functionally identical to the embodiment shown in FIG. 3, but the outer shape is substantially altered in that it is formed by a cylindrical container 23 with a small diameter which is substantially housed in a housing 24 that is relatively long and has a small outer diameter.

The housing 24 is formed by a bottom portion including a tapered portion 25 that allows access to the bottom portion of the cylindrical container 23.

In FIG. 4, it can be seen that connected to the housing 24 and associated with the one shown and the cannula 9 is in position a cylindrical container at its mouth. Entire against unwanted rib fittings FIG. 4, where FIG. 4 cylindrical can take the position of contact with the piston in the tapered line shown in dashed line 23 also includes a pumping element the device is located inside the displacement or withdrawal is secured on both components indicated by position 26. In position the container 23 occupies the lowest position in the pumping element enabling position This position is cylindrical in dependence on the stresses of the piston of the pumping element 4.

by means of a stable threading nozzle 19 on the retained sleeves 24 of the container 23 is induced

From this position with relative displacement in the axial direction between the housing 24 and the cylindrical container 23, which occupy their position against the movement of the aforementioned spring, the pumping element is displaced and later the brush bristles 13 are soaked when the starting position is reached. Said displacement in the axial direction is readily realized relative to the tapered portion 25 of the housing 24. By simply gripping the housing 24 with one hand, the end of the cylindrical container 23 can be moved with the thumb. By the aforementioned tapered portion 25, excess product may also be dispensed with when the device is overfilled. The free bottom of the aforementioned housing 24 is substantially flush with the bottom of the cylindrical container 23. In this case it counteracts the pressure of all forces acting on it. FIG. 4, in particular from the transverse detail in which the closure 20 is shown, its inner part with the structure described in more detail above can be seen. Inside the closure 20, a lid 29 is provided with a spring 30 which presses it into the closed position, as shown in FIG. 4. In the case of the intended screwing of the cap 20 on the cone nozzle 19, the mouth of the cap 29 is provided in the form of a truncated cone portion and also extends later over the cone nozzle 19 which extends outwardly. Then, only the closure 20 compresses the spring 30 holding the bristle-bearing member 13 in rotation as the bolt 20 unscrews the spring energy in a step-by-step manner, and thus requires a small axial force in another separate device.
