Abstract
A lotion application device includes a protective shell, a rotatable plate that mounts onto the shell, and a sponge secured to the plate. The sponge can be exposed and used to apply lotions to the skin, or the sponge can be concealed so the device can be transported without risk of contamination or damage to the sponge.
Description




BACKGROUND




The present invention relates to a device for applying lotions, creams or gels to the skin surface.




Lotion applicators for applying lotions to the skin are known in the prior art. These applicators are commonly used in conjunction with suntan lotion, liquid soaps, or ointments of similar viscosity, so the lotion can be applied to the skin without the user having to handle the lotion directly. As described in U.S. Pat. No. 4,299,005 (issued to Brown), U.S. Pat. No. 4,896,984 (issued to Evans), U.S. Pat. No. 5,341,538 (issued to Banome), and U.S. Pat. No. 4,171,171 (issued to Jones), the applicators typically include a body and an application sponge. The body may further include a reservoir for holding the lotion to be applied to the skin, such as described in U.S. Pat. No. 5,573,342, issued to Patalano. If the body includes a reservoir, holes or similar outlet ports are provided in the reservoir to allow the lotion to feed from the reservoir to the sponge.




One problem with the lotion applicators of the prior art is that the sponge remains exposed to the surroundings at all times, thus risking contamination of the sponge. Further, with the sponge exposed to the surroundings, it can be difficult to transport the lotion applicator, for example, to the beach, because of risk of damaging the sponge. Another problem with the lotion applicators of the prior art is that the lotion to be applied to the skin is supplied in one bottle and must then be transferred to the reservoir of the lotion applicator. This can be a messy operation and can leave the user's hands feeling sticky or greasy, which can be undesirable, such as when on the beach, or dangerous, such as when in a shower.




SUMMARY OF THE INVENTION




The present invention is a lotion application device that includes a protective shell and a sponge secured to a replaceable, rotatable plate that mounts onto the shell. The device has a closed position, in which the sponge is hidden within the shell, and an open position, in which the sponge is exposed to the surroundings. Because the plate can be rotated to hide the sponge within the shell, the risk of contamination of the sponge is reduced, and the sponge can be easily transported without risk of damaging the sponge.




In a preferred embodiment, the plate can further include a latching device that prevents the plate from rotating about its axis without the user releasing the latch.




In an alternative preferred embodiment, the lotion to be applied is encased within the sponge, eliminating the need for the lotion to be transferred to the sponge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The lotion application device depicted in the various Figures is selected solely for the purposes of illustrating the invention. Other and different application devices may utilize the inventive features described herein as well.




Reference is first made to

FIGS. 1 through 7

in which the device constructed in accordance with the present invention is generally noted by the character numeral


10


. The device


10


has as major components a shell


12


, a rotatable plate


14


which is mounted on the shell


12


, and a sponge


16


which is attached to plate


14


. The device


10


is designed to allow a user to expose the sponge


16


(“open position”), as shown in

FIG. 1

, or to conceal the sponge


16


(“closed position”) exposing only the plate


14


, as shown in FIG.


2


. When the sponge


16


is exposed, it can be used to apply lotions, such as sunscreen, moisturizer, liquid soap, or other flowable products, to the skin. When the sponge


16


is concealed, the device


10


can be transported, for example taken to the beach, without risk of contamination or damage to the sponge


16


.




Referring again to

FIGS. 1 through 7

, the shell


12


has a body


30


having a length “l”, a width “w”, and a depth at the deepest point “d”. The body


30


has a top region


36


, side walls


38


,


38


′, end walls


40


,


40


′, and tabs


42


,


42


′, and defines an interior face


32


and an exterior face


34


. The top


36


covers the sponge


16


when the applicator


10


is closed. The side walls


38


,


38


′ extend downwardly lengthwise from the top


36


, and the ends


40


,


40


′ extend downwardly from the top


36


widthwise, with the side walls


38


,


38


′ and ends


40


,


40


′ terminating to form a lip


44


, having a thickness “t”. The thickness “t” of the lip


44


is preferably representative of the thickness of the shell


12


, although the top


36


may be reinforced if desired. The side walls


38


,


38


′ are fused to the ends


40


,


40


′ where they juxtapose. The end


40


has a tab


42


, which includes an aperture


18


positioned along a longitudinal axis “x”. The tab


42


is formed by essentially parallel slits


46


,


48


cut from the lip


44


toward the top


38


. The slits


46


,


48


are approximately equidistant and on opposite sides of the aperture


18


, and are cut to approximately the same depth “s”. An essentially identical tab


42


′ is formed by slits


46


′,


48


′ on end


40


′ and has an aperture


18


′ positioned along the axis “x”. The shell


12


can have any shape that can include a top


36


, side walls


38


,


38


′, and ends


40


,


40


′, such as a rectangular block shape, a curved ovoid shape, a hollow hemispherical shape, or the like. In the preferred embodiment, the shell


12


has a slightly curved shape for ease of handling by the user. The shell


12


can be made from any material which can be formed into the desired shape, but preferably is made from a semi-rigid plastic, such as polyethylene, polypropylene, high density linear polyethylene, polyvinyl chloride (PVC), polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), high density polyethylene/ethylvinyl acetate (HDPE/EVA) copolymer, glycol-modified polyethylene terephthalate (PETG), acrylonitrile butadiene styrene (ABS), or combinations thereof, and is formed through a molding process.




As shown in

FIGS. 2

,


3


, and


6


, the rotatable plate


14


is an essentially flat piece


21


having a length “pl” and a width “pw”, and defining a front face


20


and a rear face


22


. The front face


20


has an essentially flat center section


54


to which the sponge


16


can be attached. The flat center


54


may extend to the periphery of the front face


20


, or an elevated edge


52


can optionally be included along the periphery of the face


20


. The rear face


22


may be flat, as shown in

FIG. 2

, but other shapes are acceptable. The plate


14


further includes attachment pins


24


,


24


′ that project from the piece


21


. The pins


24


,


24


′ must be long enough to project through the apertures


18


,


18


′, respectively, to hold the plate


14


in the shell


12


. With the pins


24


,


24


′ projecting through the apertures


18


,


18


′, the plate


14


can rotate about the axis “x” between the open position and the closed position. Preferably, the plate


14


can be easily removed from the shell


12


by lifting the tabs


42


,


42


′ and releasing the pins


24


,


24


′ from the apertures


18


,


18


′. This allows the user to exchange the plate


14


and sponge


16


, if so desired. The plate


14


can be made from any material which can be formed into the desired shape, but preferably is made from a semi-rigid plastic, such as polyethylene, polypropylene, high density linear polyethylene, polyvinyl chloride (PVC), polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), high density polyethylene/ethylvinyl acetate (HDPE/EVA) copolymer, glycol-modified polyethylene terephthalate (PETG), acrylonitrile butadiene styrene (ABS), or combinations thereof, and is formed through a molding process.




It may be advantageous to limit the rotation of the plate


14


within the shell


12


at certain times, such as when the device is in the open position or in the closed position. One way to limit the rotation is to provide a coordinating structure to “lock” the plate


14


in position relative to the shell


12


.

FIGS. 1

,


4


and


5


show plate


14


with an optional thumb


25


protruding from the pin


24


. The thumb


25


can cooperate with an optional notch


43


(not shown) scored into the exterior face of the tab


42


to keep the plate


14


from rotating between the opened and closed position without the user forcing the thumb


25


out of the notch


43


. More than one notch


43


may be included on the tab


42


to allow the plate


14


to be locked into different positions.




Because the plate


14


is mounted within the shell


12


but is not permanently affixed to the shell


12


, the plate


14


is preferably easily removable from the shell


12


. As shown in

FIGS. 1-6

, the tab


42


′ can include an optional release


50


′, to assist the user in bending the tab


42


′ outward, thus releasing the pin


24


′ from the aperture


18


′. An essentially identical release


50


, and essentially identical notches


43


may be included on the tab


42


. The release


50


allows for the tab


42


to be more easily lifted away from the plate


14


, so the pins


24


,


24


′ can be removed from the apertures


18


,


18


′. A new plate


14


can then be inserted into the shell


12


.




The sponge


16


, shown in

FIGS. 1

,


2


and


7


, is attached onto the front face


20


of the plate


14


. The sponge


16


is sized to allow the plate


14


to rotate along the axis “x” with the sponge


16


attached. The sponge


16


can be made from any foamed or felt material that can absorb or adsorb lotion, such as foamed polyurethane. A variety of glues or adhesives known in the art can be used to attach the sponge


16


to the plate


14


. Optionally, the sponge


16


may include a cavity within the sponge


16


which can contain a lotion, gel, or cream, such as suntan lotion or liquid soap product, or the lotion can otherwise be impregnated into the sponge


16


.




In a preferred embodiment, lotion application device


10


is constructed from a shell


12


made of high density polyethylene, a plate


14


made of high density polyethylene, and a sponge


16


made of polyurethane. The shell


12


has a length “l” of approximately 5″, a width “w” of about 3½″, and a depth “d” of about 1½″ at the centermost point of the top region


36


, and a lip


44


, having a thickness “t” of about ⅛′. The shell


12


has a slightly curved shape, but the side walls


38


,


38


′ are slightly flattened to allow for easier gripping by the user. End


40


includes slits


46


,


48


, each approximately ½″ long (“s”). The slits


46


,


48


are separated from each other by about ¾″ to form a tab


42


. Centered on the tab


42


is an aperture


18


of approximately ¼″ diameter, and above the aperture essentially parallel to the lip


44


is a release


50


extending across the tab


42


and projecting outward from the exterior face


32


of the shell


12


by about ⅛″. The tab


42


includes two notches


43


, both essentially parallel to the lip


44


, one on either side of the aperture


18


.




The plate


14


has a width “pw”of approximately


3


″, a length “pl”of about 4½″, rounded edges, and flat surfaces on the front and rear faces


20


,


22


. The attachment pins


24


,


24


′ project from the plate


14


by about ½″ along an axis “x”. Each pin


24


,


24


′ further includes a thumb


25


,


25


′, respectively, measuring about ⅛″ in length. The plate


14


is secured to the shell


12


by the pins


24


,


24


′ projecting through the apertures


18


,


18


′, respectively.




The sponge


16


has a shape similar to the plate


14


but has a width of about 2¾″, a length of about 4″, and a thickness of about ¼″. The sponge is impregnated with microencapsulated suntan lotion, and is attached to the plate


14


with pressure sensitive adhesive.




An alternative embodiment


110


of the lotion application device


10


is shown in

FIGS. 8-12

. As shown in

FIG. 8

, the lotion application device


110


may be used in conjunction with other attachments, such as a handle. The lotion applicator


110


shown in

FIG. 8

is essentially identical to the applicator of

FIG. 1

except that an ergonomically designed handle


154


(shown in

FIGS. 11

,


12


) and an optional knob


160


(shown in

FIG. 10

) have been attached to the device


110


, and the shell


112


has been modified as shown in

FIGS. 9 and 9A

to include latching indents


152


for accepting the teeth


156


of the handle


154


. Similar to the device


10


of

FIG. 1

, the device


110


includes a rotatable plate


114


with an attached sponge


116


. The plate


114


is mounted in the shell


112


in the same manner that plate


14


mounts to shell


12


. The handle


154


can be fixedly attached to the shell


112


of the device


110


, or it can be removable at the user's discretion. The handle


154


can have any of several known designs, such as a long handle projecting from the shell


112


(as shown in the FIGS.


8


-


12


), or a strap-type handle extending across the exterior face


134


of the shell


112


(not shown). The shell


112


can also have shapes other than the shape shown in the

FIGS. 1-12

, with the plate


114


and sponge


116


being shaped to complement the shell


112


configuration.




It is understood that, in light of a reading of the foregoing description and drawings, those with ordinary skill in the art will be able to make changes and modifications to the present invention without departing from the spirit or scope of the invention, as defined herein.
