Description

Hand-held spraying device
Technical Field
The present invention generally relates to a hand-held spray device for infant care.
Background
Infant care requires frequent changing of diapers along with wet wipes for cleaning. However, it is desirable to eliminate or reduce the need for such wet wipes.
It will 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.
SUMMERY OF THE UTILITY MODEL
A conveniently ergonomic and portable hand-held spray device for directing a spray of water to clean the buttocks of an infant is provided herein, thereby eliminating or reducing the need for wet wipes.
The device includes a flexible (such as silicon or the like) bellows that can engage a substrate, which is typically rigid and plastic (such as ABS or the like), to retain a liquid (such as water or the like) therein. The base defines a nozzle therethrough such that squeezing of the bellows pressurizes the contents therein, forcing liquid through the nozzle as a direct spray for cleaning the buttocks of the infant.
The base may include a flat lower surface, thus allowing the device to be upright and easily picked up by the bellows.
In a preferred embodiment, the bellows comprises a bulbous section towards the base, the bulbous section narrowing from the base towards the terminal section. Furthermore, the bellows further preferably comprises a notch in one side of the bellows between the bulbous section and the terminal section, thereby shaping the bellows ergonomically for easy pick-up, gripping and squeezing. For example, in one embodiment, a thumb may be positioned within the recess to squeeze the bellows between the thumb and the opposing index finger. Alternatively, the index finger may engage in the recess, with the thumb pressing relatively against the terminal section.
In an embodiment, the device comprises a series of valves and delivery tubes, a pump mechanism and an air outlet for different modes of operation and for controlling the liquid spray emitted from the device.
Furthermore, the device may comprise an external air outlet which is oriented to intersect the path of the nozzle, thus providing an interrupted flow or atomisation effect.
The device may comprise a delivery tube to supply air or liquid content separately from the interior of the bellows. The delivery tube may include an arrangement of valves for controlling the flow and direction of air and water.
In an embodiment, the device may comprise an internal pump having a lever that bears against a fulcrum to press the plunger to force the liquid contents through the nozzle. The lever may be located adjacent to the notch and may comprise a counter strut which abuts against the opposite inner surface of the bellows such that the pump may be activated by squeezing the bellows at the notch opposite the index finger pressing against the opposite side of the bellows.
The apparatus may further include a cover that is capable of rotatably engaging the outer section of the base. The cap may be rotated to lock the nozzle and thereby prevent leakage and/or fall off when the device is not in use. In particular, the cap may include an orifice and a stopper selectively disposed adjacent to a lower surface projection of the outer section having the nozzle therein to allow novelty to be injected through the orifice or to be blocked by the stopper.
Other aspects of the utility model are also disclosed.

Detailed Description
Fig. 1 shows a hand-held spray device comprising a flexible bellows 101, the flexible bellows 101 being coupled to a base 103 for retaining a liquid (such as water, etc.) therein. The base 103 preferably has a circular cross-section and may include a flat lower surface for standing upright on a surface.
Bellows 101 may be made of a flexible, waterproof material, such as silicone or other soft plastic or polyurethane-based resins (polyurethane-based resins), and the like. The base 103 is preferably rigid, such as made of ABS or other suitable hard plastic or the like.
Referring to fig. 2, the bellows 101 may include a bulbous section 104 adjacent the base 103, the bulbous section 104 narrowing from the base 103 to a terminal section 109 opposite the base 103. Bellows 101 may define a side notch 106 between bulbous section 104 and terminal section 109 at a side of bellows 101.
The base 103 may include an outer section 113, the outer section 113 engaging the inner section 131 to clamp the rim 115 of the bellows 101 therebetween. The outer section 113 may be unscrewed from the inner section 113 in order to refill the bellows 101.
The base 103 may further include a cover 114, the cover 114 being rotatably coaxially engageable with the outer section 113 in a manner described in further detail below.
In the embodiment shown in fig. 2, the base 103 may have a liquid inlet 112 adjacent the base 103 and an air inlet 108 remote from the base 103. An air inlet 108 may be formed at the distal end of delivery tube 107. Thus, when held in the orientation shown in FIG. 2, the liquid contents thereof submerge the liquid inlet 112, leaving the air inlet 108 exposed to the air therein.
The liquid inlet 112 leads to the nozzle 111. Thus, when bellows 101 is squeezed and the contents therein are pressurized, liquid is forced out of nozzle 111 at high velocity via liquid inlet 112.
At the same time, air is forced through the air inlet 108, down the delivery tube 108 and through the outer air outlet 110. As can be seen in fig. 2, the outer air outlet 110 may be directed to intersect the path of the nozzle 111 in order to disrupt the laminar flow of liquid from the nozzle 111, thereby creating a disrupted flow or atomization effect.
Fig. 3 shows a variation of the embodiment of fig. 2, wherein the device 100 comprises a further delivery tube 116 abutting the liquid inlet 112. The further delivery tube 116 may comprise a liquid inlet 117 towards the base 103, the liquid inlet 117 similarly being submerged within the liquid content when the device 100 is held in the orientation of fig. 3.
Fig. 4 shows an alternative embodiment, wherein the device 100 comprises a pump 118, the pump 118 comprising a lever 119, the lever 119 abutting against a fulcrum 120 to force a plunger 121 into the chamber to pressurize the liquid content therein, which in turn flows via the nozzle 111.
In the embodiment shown, lever 119 is located adjacent to notch 106 such that depression of bellows 101 at the notch depresses lever 119. The lever 119 may include a return mechanism (such as a coil spring, compression spring, etc.) that returns the lever 119 against the notch 106.
The pump 118 may include a liquid inlet tube 122.
The pump 118 may comprise a counter-strut 123, which counter-strut 123 acts on the inner surface of the bellows 101 opposite the lever 119. Thus, for example, to pump 118, thumb 106 may be engaged within the recess opposite the index finger holding the opposite side of bellows 101.
Fig. 5 shows an embodiment of the device 100 without the outer air outlet 110. In this embodiment, the squeezing of bellows 101 forces pressurized water through nozzle 111. In this embodiment, the device 100 may comprise a delivery tube 116, which delivery tube 116 may comprise a liquid inlet 117 towards the base 103, which liquid inlet 117 is thereby submerged in the liquid content, allowing liquid to flow into the delivery tube 116 for discharge via the nozzle 111.
Figure 6 shows a variation of the embodiment of figure 5, wherein delivery tube 116 comprises a plurality of duckbill valves.
According to this embodiment, the delivery tube 116 includes a liquid inlet duckbill valve 126 toward the base 106 to allow liquid contents to enter the delivery tube 116 but not escape therefrom.
The delivery tube 116 may include an air inlet duckbill valve 125, the air inlet duckbill valve 125 allowing air trapped at the upper region of the bellows 101 to enter into the delivery tube 116.
In addition, delivery tube 116 may include an air outlet duckbill valve 124, allowing air to escape into bellows 101.
7-9 illustrate embodiments in which the cover 114 is rotated relative to the outer section 113 to alternatively align the aperture 108 or the stop 130 with the nozzle 111.
As shown in fig. 7, the lower surface of the outer section 113 may include a protrusion 127, the protrusion 127 defining the nozzle 111 concentrically therethrough.
The cover 114 may include a rim 113 rotatably engaged with the outer section 113. The cover 114 may include a track 132 to control the degree of rotation between the cover 114 and the outer section 113.
Thus, at one degree of rotation, the aperture 128 mates with the protrusion 127, thereby allowing liquid to escape through the nozzle 111.
However, to the opposite degree of rotation, the stop 113 is mated against the protrusion 127. In the illustrated embodiment, both the protrusion 127 and the stopper 130 may include flat faces that are configured to interferingly seal face-to-face as shown in fig. 9.
The stopper 130 may include a guide slope 129 to guide the protrusion 127 to a flat surface of the stopper 130.
The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the utility model. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the utility model. Thus, the foregoing descriptions of specific embodiments of the present invention are presented for purposes of illustration and description.
