Abstract
There is disclosed a device for application of a flowable paste-like material such as mastic, e.g. between two surfaces such as tiles or onto a surface. Mastic applicators typically having a frusto-conical shaped nozzle are known. However, such have a number of disadvantages. For example, “keying” of the mastic is necessary to achieve a flat surface and a further wiping operation is required to achieve a reasonable finish. Accordingly, the invention provides a nozzle (10) having an outlet end including a first side (16 b) and a second side (16 a) which extends from a third side (16 d), which first and second sides (16 b ,16 a) taper towards one another in a direction away from the third side (16 d). Beneficially first respective ends of the first and second sides (16 b ,16 a) are connected by the third side (16 d) and second respective ends of the first and second sides (16 b ,16 a) are connected by a fourth side (16 c) of the outlet end.
Description
- This invention relates to a device or nozzle for application of a non-solid material, in particular, though not exclusively, this invention relates to a device for application of mastic or the like, e.g. between two surfaces such as tiles or onto a surface.
- The traditional method of applying mastic is via a frusto-conical shaped nozzle. However, this method has a number of disadvantages. For example, keying (i.e. dragging a flat edge along a top surface) of the mastic is necessary to achieve a flat surface, and a further wiping operation is required to achieve a reasonable finish. Furthermore, to increase the width of the applied mastic requires cutting a more shallow angle along the length of the cone. This produces a long narrow elliptical shaped outlet which increases the degree of difficulty in applying the mastic as the working angle, e.g. around adjacent surfaces is significantly reduced and in some places the angle is unworkable.
- Moreover, during application, with a frusto-conical nozzle, a convex finish is generally created and bulging/slumping of the mastic often occurs. This results in small areas of dirt/water accumulating which encourages mould growth.
- Additionally, in an attempt to produce a satisfactory smooth finish, people often wet their fingers and draw their fingers across the mastic. This is not recommended due to health risks.
- People also find it difficult to apply mastic, and often during application the mastic goes outwith the intended area. This can be attributed to a lack of control at the nozzle because of the small area and angle of contact between the nozzle and the surfaces to which the mastic is being applied.

FIG. 8 a side view of the nozzle shown inFIGS. 1 to 4 fitted together with a frusto-conical nozzle, a cartridge and a cartridge gun. - Referring to
FIGS. 1 to 4 there is shown a nozzle, generally designated 10, according to an embodiment of the present invention. Thenozzle 10 comprises a circular shapedinlet 12 and a bi-lateral symmetrical trapezoid shapedportion 14 which tapers to a bi-lateral symmetrical trapezoidal shapedoutlet 16. The bi-lateral symmetrical trapezoid shapedoutlet 16 has twonon-parallel sides 16 a,16 b and twoparallel sides 16 c,16 d, whereinside 16 d is longer than side 16 c. - Typical dimensions for the
nozzle 10 are shown inFIGS. 2 and 4 . In this embodiment, the circular shapedinlet 12 has an inlet diameter A of 12 mm; the bi-lateral shapedsection 14 has a length B of 25 mm and a starting height C of 10 mm; one side of the bi-lateral shaped section starts with a width D of 24 mm tapering to a width E of 4 mm; another side of the bi-lateral shaped section starts with a width of 18 mm. -
FIG. 3 is a sectional side view of thenozzle 10 which shows that the inside surface of the annular shapedinput 12 has ascrew thread 18. - The
nozzle 10 is formed from a suitable plastics material. The plastics material may typically be approximately 1 mm in thickness. Thenozzle 10 can be formed by standard extrusion techniques or can be formed from two separate parts which are seam welded together. -
FIG. 5 is an isometric view of a frusto-conical nozzle 22 having anexternal screw thread 23. - As shown in
FIGS. 7 and 8 , thenozzle 10 is screwed onto the frusto-conical nozzle 22. Although not shown, it will be appreciated that thenozzle 10 may be merely pushed onto the frusto-conical nozzle 20 and retained thereon by an interference fit. Alternatively thenozzle 10 and frusto-conical nozzle 22 may be formed in one piece. - As shown in
FIG. 8 , thenozzle 10 and frusto-conical nozzle 22 are attached to acartridge 24 of, for example, mastic which is held in astandard cartridge gun 26.

nozzle 10 is placed in a gap between, for example, tiles or surfaces to which mastic is to be applied. Thenozzle 10 is normally placed so that the narrow end of the bi-lateral shapedend 16, i.e. side 16 c, is against or adjacent the surface to which mastic is to be applied.

nozzle 10 may be cut to select the width and size of theoutput end 16. To assist in such cuttingweakening operating lines 15 across and/or around thenozzle 10 may be formed during its initial moulding process as shown inFIG. 1 . - It should be noted that, due to the shape of the
nozzle 10, mastic can be efficiently applied around a corner due to the larger surface contact obtained with a standard frusto-conical nozzle. - After use, the
nozzle 10 can be unscrewed, cleaned and stored for further use. - It will be appreciated that the embodiment of the present invention hereinbefore described is given by way of example only, and is not meant to limit the scope of the invention in any way.
- In particular it will be appreciated that in a modification the nozzle may be directly attached to, or integrally formed with, the cartridge without need for an intervening frusto-conical nozzle.
