DESCRIPTION:
BRIEF SUMMARY
This invention pertains to a device for applying a fluid to a surface and more specifically, to a device making it possible to apply a predetermined quantity of a liquid to a surface by coating.
When one wishes to manually apply a relatively limited amount of liquid on to a surface, for example, a few millimeters of a solvent, liquid glue or a varnish, the most simple method consists of using a brush-type applicator which is dipped into the liquid to be applied and is next passed over the surface to be coated or cleaned so that a film of liquid may be placed thereon.
This method involves the use of a container holding a relatively large quantity of liquid and involves considerable loss of liquid and an irregular application.
To make it possible to apply a predetermined amount of liquid, it has been proposed to use single doses, for example, in the form of a breakable ampule or a breakable capsule containing a specific quantity of liquid, which is broken in order to spread the liquid on an absorbent surface or a brush, so that it can be spread over the surface. However, breaking the ampule or capsule containing the liquid is often difficult; it does not always occur at the desired location, and the user can be injured by contact with debris from the ampule or the liquid released.
British Pat. No. 2,001,285 describes a device for applying a liquid glue, comprising a plunger making it possible to pierce and compress a cartridge to cause the glue to issue through an opening blocked by a ball. In U.S. Pat. No. 4,389,132, the liquid to be applied is also contained in a plastic cartridge pierced by a tube. These known devices, however, are relatively complex and do not prevent the applicator by which the liquid on the surface is to be coated from becoming soiled.
The object of this invention is a device which is simple, inexpensive to produce and, which makes it possible to easily and safely apply a predetermined amount of a liquid contained in a breakable ampule or breakable capsule by coating.
The device according to this invention is the type which comprises a dose of liquid in a breakable ampule or breakable capsule, and has a tubular body which is open at one end accommodating a breakable ampule or breakable capsule which is essentially cylindrical and enclosed in a flexible, resistant casing, and having in its wall at least two flexible blades placed essentially opposite each other, with each of these blades having at least one tappet directed towards the inside and offset longitudinally with respect to the corresponding tappet of the other blade.
The flexible blades can advantageously be made by a simple cutout in the tubular body.
The breakable capsule or breakable ampule preferably is in the shape of a cylinder, extended so that it can be introduced into the tubular body through its open end. It is enclosed in a casing made of flexible and resistant material, of the same essentially cylindrical shape, closed at one end with an absorbent material acting as an applicator wick or pad, which extends outside of the tubular body when the ampule or the capsule is placed therein.
At its end opposite the opening, the tubular body preferably has a pusher, comprised for example of a plunger, which can slide freely along the longitudinal axis. This pusher is forced back when the capsule or ampule is placed in the tubular body, so that a shaft connected to the pusher protrudes from the tubular body, at its end opposite the opening. This shaft can next be activated to force back the pusher and eject the capsule or ampule from the tubular body, after which the device according to the invention is used.
When the capsule or ampule is placed in the tubular body, it forces the tappets and the flexible blades to which they are attached outward. By exerting pressure on the blades, the tappets, which are pointed and are offset longitudinally with respect to each other, exert a shearing effect which causes the ampule to break through the casing, and prevent the casing from sliding outside of the tubular body.
