This invention relates generally to a handheld spray device for baby care.
Care of babies entails frequent diaper changing in combination with wet wipes for cleaning. It would be desirous however to eliminate or reduce the need for such wet wipes.
It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.
There is provided herein a handheld spray device conveniently ergonomic and portable for directing a spray of water to clean a baby's bottom, thereby eliminating or reducing the requirement for wet wipes.
The device comprises a flexible bellow such as of silicon which may engage a base, typically rigid and of plastic such of ABS so as to retain liquid such as water therein. The base defines a nozzle therethrough such that squeezing of the bellow pressurises the contents therein, forcing liquid via the nozzle as a direct a spray for cleaning the baby's bottom.
The base may comprise a planar undersurface, thereby allowing for the standing upright of the device, readily available for picking up by the bellow.
In a preferred embodiment, the bellow comprises a bulbous section towards the base which narrows towards a terminal section away from the base. Furthermore, the bellow further preferably comprises a notch within a side of the bellow between the bulbous section and the terminal section thereby shaping the bellow ergonomically for convenient pickup, gripping and squeezing. For example, in one embodiment, the thumb may locate within the notch so as to squeeze the bellow between the thumb and the opposing forefingers. Alternatively, the forefingers may be engaged within the notch, with the thumb pressing oppositely over the terminal section.
In embodiments, the device comprises a series of valves and delivery tubes, pump mechanisms and air outlets for various modes of operation and for controlling the spray of liquid emanating from the device.
Furthermore, the device may comprise an exterior air outlet orientated to intersect the path of the nozzle, thereby providing disrupted flow or misting effect.
The device may comprise delivery tubes to separately source air or liquid contents from an interior of the bellow. The delivery tubes may comprise an arrangement of valves for controlling the flow and direction of air and water.
In embodiments the device may comprise an interior pump having a lever acting against a fulcrum to depress a plunger to force liquid contents via the nozzle. The lever may locate adjacent the notch and may comprise a counter brace acting against an opposite interior surface of the bellow such that the pump may be activated by squeezing the bellow at the notch opposing the forefingers pressing against an opposite side of the bellow.
The device may further comprise a lid which may rotatably engaged and outer section of the base. The lid may be rotated to lock the nozzle, thereby preventing leakage and/or dropping when the device is not in use. Specifically, the lid may comprise an aperture and a stopper which selectively collocate adjacent an undersurface protrusion of the outer section having the nozzle therein to either allow the novel to inject liquid via the aperture or be blocked by the stopper.
Other aspects of the invention are also disclosed.
Notwithstanding any other forms which may fall within the scope of the present invention, preferred embodiments of the disclosure will now be described, by way of example only, with reference to the accompanying drawings in which:
The bellow 101 may be made from a flexibly watertight material such as silicon or other soft plastics or urethane-based resins. The base 103 is preferably rigid such is made of ABS or other suitable hard plastic.
With reference to
The base 103 may comprise an outer section 113 which engages an inner section 131 to clamp a rim 115 of the bellow 101 therebetween. The outer section 113 may be unscrewed from the inner section 113 to refill the bellow 101.
The base 103 may further comprise a lid 114 which may rotatably coaxially engage the outer section 113 in the manner described in further detail below.
In embodiments shown in
The liquid inlet 112 leads to a nozzle 111. As such, when the bellow 101 is squeezed and the contents therein pressurised, liquid is forced via liquid inlet 112 out from the nozzle 111 at high velocity.
Simultaneously, air is forced via the air inlet 108, down the delivery tube 108 and via an exterior air outlet 110. As can be seen in
In embodiments shown, the lever 119 locates adjacent the notch 106 such that depressing the bellow 101 at the notch thereby depresses the lever 119. The lever 119 may comprise a return mechanism such as a coil spring, compression spring or the like returning the lever 119 against the notch 106.
The pump 118 may comprise a liquid inlet tube 122.
The pump 118 may comprise a counter brace 123 acting in opposition to the lever 119 against an interior surface of the bellow 101. As such, for example, for pumping the pump 118, a thumb 106 may be engaged within the notch in opposition against forefingers holding an opposite side of the bellow 101.
In accordance with this embodiment, the delivery tube 116 comprises a liquid inlet duckbill valve 126 towards the base 106 to allow liquid contents to enter the delivery tube 116 but not escape therefrom.
The delivery tube 116 may comprise an air inlet duckbill valve 125 allowing air entrapped at an upper region of the bellow 101 to into the delivery tube 116.
Furthermore, the delivery tube 116 may comprise an air outlet duckbill valve 124, allowing air to escape into the bellow 101.
As is shown in
The lid 114 may comprise a rim 113 engaging the outer section 113 in a rotatable manner. The lid 114 may comprise a rail 132 to control the extent of rotation between the lid 114 and the outer section 113.
As such, at one extent of rotation, the aperture 128 collocates with the protrusion 127, thereby allowing liquid to escape via the nozzle 111.
However, at an opposite extent of rotation, the stopper 113 collocates against the protrusion 127. In the embodiment shown, both the protrusion 127 and the stopper 130 may comprise planar faces for face-to-face sealing as is illustrated in
The stopper 130 may comprise a lead up a ramp 129 to guide the protrusion 127 to the planar face of the stopper 130.
The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that specific details are not required in order to practise the invention.
