Definitions
- the present invention relates to a device of the gun type for the delivery of fluids contained in bottles or the like, which comprises a rigid body in which the pipes for emission of the liquid are formed and to which an operating lever for delivery is hingeably connected, there being provided resilient means integral with the body itself and designed to interfere with a part of said operating lever so as to cause the return movement of the latter into the rest position after operation thereof for delivery.
- said caps or tops include gun-type sprayers (also called triggers) which, although they are constructionally made in different ways, are all based on the operation of a piston by means of a lever, called a trigger, which is hingeably mounted on the body of the cap or top and which, pushed by the user to the end-of-travel position, causes an increase in the pressure inside the bottle and hence drawing up of the product along the delivery pipe and the forced emission of said product through the said nozzle.
- gun-type sprayers also called triggers
- the operating lever is then brought back into the rest position by a resilient element, normally consisting of a steel spring, which resets the device for the next delivery.
- the technical problem which is posed, therefore, is that of providing a gun-type delivery device which is made entirely of plastic and can be recycled, without additional parts made of material different from the basic recyclable material.
- the delivery device should be made with a small number of parts which are integral with one another and can be manufactured directly using a moulding process, without the need for assembling accessory parts which could cause accidental breakages or separation and which, in any case, require an assembly stage.
- a device for delivering fluids contained in bottles or the like comprising a rigid body in which the pipes for drawing in and directing the said fluid are formed and to which the means for operating a piston delivering the fluid are hingeably connected, there being provided resilient means which are integral with the body itself and designed to interfere with a part of said operating lever so as to cause the return movement of the latter into the rest position after operation thereof for delivery.
- the gun-type delivery device comprises a rigid body 10 which is obtained by means of moulding or a similar process and which comprises: the pipes for drawing up 11 and directing 12 the fluid to be delivered, a cylinder 15 substantially parallel to the said directional pipe 12, a gusset 18 integral with the drawing-up pipe 11, but extending on the opposite side with respect to the directional pipe 12, and a rib 17 integral with said gusset 18.
- one end of the drawing-up pipe 11 is integral with an annular element 11a sealingly connected, by means of a cap 2, to the neck of fluid container 1.
- the said rib 17 consists of a first section 17b integral with the gusset 18 and substantially parallel to the drawing-up pipe 11 and a second section 17a which is free and substantially perpendicular to said drawing-up pipe 11 so as to form a means reacting resiliently to the deformation imparted by the trigger of the gun, as will emerge more clearly below.
- Two pins 14a substantially perpendicular to the said pipe extend from the external surface of the exit pipe 12 and receive, hingeably mounted on them, the lever 14 forming the trigger of the gun.
- Said lever 14 in turn has, in a suitable position, a pin 15a on which the rod 15b of a pumping piston 15c is hingeably mounted and which, being displaced inside the cylinder 15, causes an increase in pressure inside the pipe 11 and hence the bottle 1 and the consequent delivery of the fluid through the pipes 11,12 and the end nozzle 12a of the directional pipe 12.
- the end of the operating lever 14 is joined to the directional pipe 12 and extended by a lug 16 forming a substantially obtuse angle with the lever 14 itself.
- the delivery device may be completed by an aesthetically finished protective casing 19 which has substantially the shape of an "overturned U” (Fig. 2) fitted in a known manner to the gun.
- both the lug 16 integral with the lever 14 and the rib 17, forming the resilient reaction means may have different configurations.
- the lug 116 integral with the lever 14, may in fact be prolonged in the opposite direction to that of the delivery nozzle 13 and have a free end 116a bent so as to engage with the rib 117, the fixed section 117b of which, in this case, is attached to the body 10 at the top end of the drawing-up pipe 11 and extends in a substantially horizontal direction, and the free end of 117a of which is arched towards the bottom as far as the position where it makes contact with the end 116a of the lug 116.
- Fig. 7 finally shows a further example of embodiment of the gun-type delivery device according to the invention, in which the lug 216 integral with the lever 14 instead has very small dimensions, while the free part 217a of the rib 217 is extended towards the delivery nozzle 13 so as to ensure interference with the lug itself.
- the lug 216 is rigid.
- the body of the delivery gun according to the invention may be made with a single moulding operation during which the resilient means for the return movement of the operating lever are also manufactured, thereby making it possible to avoid the fitting, during the assembly stage, of an additional component such as a spring or the like, said fitting operation being in any case costly and also requiring programmed storage of the various parts to be assembled.
- the resilient components which cause the return movement of the trigger into the rest position may be realized either in the form of the single rib integral with the body of the delivery device or else divided up in the form of any combination of the rib itself and the lug integral with the trigger of the gun.
- the resilient reaction is also concentrated entirely on the lug of the trigger which reacts against a totally rigid rib.
