DE582408C - Application brush for cleaning products, especially shoe care products - Google Patents

Description

The invention relates to an application brush for cleaning agents, in particular shoe care agents, Its hollow handle, designed as a coating material container, is neck-shaped over the brush wood is tapered, with a spring pressure valve with a through the container part Container lid is arranged outwardly guided valve spindle.

However, the known application brushes of this type have various disadvantages in their Design type; so they either lack an automatic air supply at all, whereby a Continuous automatic seepage of the contents impossible despite opening the outlet valve will. In other cases, an automatic air supply is only possible with the help of each time the outlet valve is opened a cumbersome lever linkage operated by the valve rod,

The subject of the avoids these shortcomings Invention. It consists in the fact that the valve spindle guided like a stuffing box in the container cover provided with a channel in its upper end for the automatic supply of air into the container, which is emptied during use whose inner opening is through the spindle seal when the valve is closed Connection with the container interior is brought.

The subject of the invention is shown in the drawing in several exemplary embodiments, namely show

Fig. Ι and 2 two such application brushes for cleaning agents with somewhat different internal facilities and two ³ ^ different brushes in longitudinal section,

Fig. 3, also in longitudinal section, another Embodiment.

The application brush for cleaning agents or the like can be made of any building material. It consists of a conical, round, the brush handle forming housing a with cover α ¹ , which forms one piece with the brush holder b; also from the brush c and from the inner device, which ^{are different in the individual 4} ^ embodiments and will be explained in more detail later. The housing α is tapered neck-like by a certain height immediately above the brush holder b. This neck neck either takes a 5 <? special, a valve seat forming body d in itself (Fig. 1 and 2) or forms the valve seat itself (Fig. 3). A spring-loaded valve ball e or a hemisphere f or a plate g with a sealing washer h is supported against the valve seat and connected to a push rod i guided through the screwed-on closure cover a ¹ . By pressing it down, the outlet is released for the purpose of running the filled liquid j into the brush c, c ¹ . The air inlet required for the contents to run out is through an air channel k provided on the upper part of the push rod i , the outlet opening k ^{1 of} which, depending on the embodiment, of the push rod i is either in the stuffing box / closed in the raised position, ie in the rest position, or in other cases -

len protrudes beyond the cover α ¹ into the open. According to the embodiment according to Fig. Ι this push rod consists of two parts i, i ¹ and is cushioned by a helical spring m in itself. According to the embodiment according to FIG. 2, the cover α ¹ is sealed by a rubber ring η and the rod i is sealed by a specially inserted rubber washer 0. According to the embodiment. According to Fig. 3, the cover a ¹ and push rod i are sealed by a common rubber washer p, with the valve closing in both cases (Figs. 2 and 3) by a buffer spring q .

The mode of operation of the new application brush for cleaning agents when in use is as follows: By pressing down the push rod i , the outlet valve e, f or g is opened and thereby also the inner one at the same time

ao opening k ¹ of the air inlet channel k associated with the container interior in communication, according to which an unhindered escape of the contents of j for the filling of the brush c and c ¹ is performed until the pressure on the pressure rod i is canceled, which then automatically to their Springs back to rest position and both the outlet valve e, f or g and at the same time the air inlet channel k closes again.

Claims (1)

Claim: Application brush for cleaning agents, in particular shoe care agents, the hollow handle of which is designed as an application compound container and tapers in the shape of a neck above the brush wood, a spring pressure valve with a valve spindle extending through the container lid being arranged in this container part, characterized in that the stuffing box-like ^{in the container lid (α 1) is arranged} Valve spindle (t) for automatic air supply into the container, which empties during use. (α) is provided in its upper end with a channel (k) , the inner opening (& ¹ ) of which is brought out of communication with the interior of the container by the spindle seal when the valve is closed. 1 sheet of drawings
