Definitions

• the present invention relates to a mixing cover construction, which has been specifically designed for paint vessels and the like.
• This shaft is coupled to a motor, in order to cause the mixing screw element to be evenly rotated.
• Prior covers are provided with a delivery spout which frequently is affected by great tightness problems, as well as further problems related to the removal of the product drops susceptible to be formed at the delivery spout.
• the aim of the present invention is to overcome the above mentioned drawbacks, by providing a mixing cover, specifically designed for paint vessels and the like, which is provided with a delivery spout specifically designed for allowing both a partial opening and a full opening of the spout, while preventing drops or the like from forming, thereby allowing a perfect metering to be obtained.
• a main object of the present invention is to provide such a mixing cover which can be applied to like size vessels, while providing a satisfactory operation.
• Another object of the present invention is to provide such a mixing cover which is devoid of any deleterious leakages.
• Yet another object of the present invention is to provide such a mixing cover construction which can be easily made starting from easily commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
• a mixing cover specifically designed for paint vessels, comprising a plate element which can be tightly coupled to a vessel, and rotatably supporting a mixing screw element, characterized in that said mixing cover further comprises, on a delivery spout thereof, a shutter element adapted to provide a partial opening by sliding across said spout and a full opening by tilting said shutter element.
• Figure 1 is a schematic perspective view illustrating the mixing cover construction according to the present invention
• Figure 2 illustrates the mixing cover with the delivery spout thereof in a closed position
• Figure 3 illustrates the mixing cover with the delivery spout thereof in a partially opened position
• Figure 4 illustrates the mixing cover with the delivery spout thereof in a fully opened position
• Figure 5 is a perspective view illustrating the sealing gasket arranged between the plate element and the product vessel
• Figure 6 is a cross-sectional view illustrating the sealing gasket of figure 5;
• Figure 7 is a further schematic cross-sectional view illustrating the connection of the shaft end portions and the mixing screw element.
• Figure 8 is a further schematic perspective view illustrating the shaft bushing for allowing the shaft to pass through the mixing cover according to the pre ⁇ ent invention.
• the mixing cover construction according to the present invention which has been specifically designed for paint vessels and the like, and which is generally indicated by the reference number 1, comprises a plate element 2 which can be associated with a vessel 3, and being provided with a gripping handle 4 radially extending and adjoining the product vessel 3.
• a polygonal shaft 11 which, at the end portion thereof, supports a mixing screw element 12.
• the plate element 2 in particular, defines a delivery spout 20, which is closed by a substantially laminar shutter element 21.
• a main feature of the present invention is that the shutter element 21 can be slidably displaced in order to provide a partial opening, and then it being adapted to be turned to assume a tilted position, to fully open the passage through the delivery spout 20.
• the shutter element 21 is provided with ears 22 which are pivoted to the end portions of a slider 23 which is slidably driven since it is restrained by a restraining pin 24 coupled to fork arms 25 projecting from the plate ⁇ like element.
• the slider 23 is provided with a cross-member 26, therewith are engaged the driving arms 27 of a driving pushbutton 28 which is pivoted to said plate-like element.
• Spring means are moreover provided for holding the shutter element 21 in a closed condition and which, in particular, comprise coil springs 30 associated with an end portion of the pin 24.
• this pin will be pressed on the slider 23, the springs engaging, at the other end portions thereof, with said slider, near said cross-member, and extending on a transmission pin 31 rigid with said plate-like element.
• the mentioned springs 30 will provide on the slider a pulling force so as to hold the shutter element 21 pressed on the spout.
• the shutter element 21 comprises moreover, as shown, guide pins 35 projecting laterally with respect to said shutter element 21.
• the abutment elements 36 are formed on shoulders 37, rigid with the mentioned plate element, thereby the shutter element, being restrained for further moving, will be caused to turn since the slider will pivot engage with ear elements 22 at a distance from the pivot pins; thus, the shutter element will be caused to turn about the pins 35, thereby fully opening the delivery spout.
• the shutter element 21 By releasing the operating push-button, the shutter element 21 will be caused to close, thereby providing a shaving type of operation so as to remove any drops or the like.
• the above disclosed device will allow to provide a partial opening, by simply causing the shutter element 21 to slide across the delivery spout 20 thereof, or a full opening, by causing the delivery spout to turn.
• the plate element 2 is moreover provided, at the under surface thereof, with a sealing gasket 40 including a pair of sealing lips 41 extending for a portion in a radial direction, thereby fitting paint vessels of different size.
• peg elements 42 extend, which engage in corresponding holes 43 formed through the plate element and being upset so as to provide a firm joint.
• the sealing gasket in particular, is clamped by slanted pawls 45 which are actuated by small levers 46 provided on the top portion of the mixing cover, so as to axially press the sealing gasket to provide a perfect sealing.
• the coupling between the mixing screw element 12 and the driving shaft 11 is performed through a compensating spring 50, engaging, by the head 52 thereof, in an abutment 53 as provided at the end portion of the core of the mixing screw element.
• the driving shaft 11 which, on the top end portion thereof is provided with a fork element 60 for engaging a motor reducing unit or the like, holding the driving shaft in a turning condition, is slidably engaged in a bushing 10.
• This bushing is rotatably housed in a cylindric seat 70, defined by the plate element and having a spiral rib 71, preventing any paint portions from exiting as the driving shaft is turned.
• a mixing cover construction which is very safe and flexible in operation and which, moreover, can be fitted to paint vessels of different size.
• the used materials provided that they are compatible to the intended application, as well as the contingent size and shapes, can be any according to requirements.
