Description

FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to deodorizer devices and methods, and particularly to devices and methods for deodorizing shoes.

Shoe odor is a common problem. For this reason, it is generally recommended not to wear the same pair of shoes for extended periods of time in order to permit them to air out by themselves. However, this is not always possible or convenient. Therefore, dispensers have been developed for dispensing deodorizer materials directly into the shoes, but such dispensers dispense the deodorizer material from the top of the dispenser. This is somewhat awkward since the dispenser must be held by one hand and the shoe held by the other, and the user must manipulate the dispenser and/or the shoe in order to dispense the material within the shoe. Moreover, with the conventional shoe deodorant sprays, it is almost impossible to spray into the foot portion of high boots or high top sneakers.

OBJECTS AND BRIEF SUMMARY OF THE INVENTION

An object of the present invention is to provide a device and method having advantages in the above respects for deodorizing shoes.

According to one aspect of the present invention, there is provided a deodorizer device for deodorizing shoe, comprising: a container containing deodorizer material; and a dispenser assembly at one end of the container for dispensing deodorizer material therefrom; the dispenser assembly including a feed tube having one end located within the container and the opposite end communicating with at least one discharge opening externally of the container for discharging deodorizer material laterally of the container; the dispenser assembly further including an actuator attached at one end to the feed tube; the actuator being in the form of a cap having a socket at one end coaxial with, and dimensioned to receive, the opposite end of the feed tube, the opposite end of the cap being dimensioned and configured to enable the container to stably rest in the inverted position within the shoe with the one end of the container and the dispensing assembly disposed within the shoe, and the opposite end of the container extending outwardly of the shoe, to enable a quantity of the deodorizer material to be dispensed into the shoe by pressing against the opposite end of the container.

The present invention thus distinguishes from conventional shoe sprays, which have the dispensing valve located on the top of the container and are displayed in stores, kept by the consumer, and used by the consumer, in this upright position. A device constructed in accordance with this feature of the invention would have the dispensing valve located on the bottom of the container, and would be displayed, stored and used with the dispensing valve on the bottom. This means the package should be stable when standing in this inverted position. By having the package stable in this inverted position, the user can easily pick it up, place it directly into a shoe (without inverting it), and just press down to actuate the valve. With conventional shoe sprays the valve is actuated by a finger pressing against the actuator button, whereas in the novel device, the valve is actuated by the shoe pressing against the actuator.

According to a further aspect of the present invention, there is provided a method of deodorizing shoes, by providing a deodorizer device as described above; inserting the deodorizer device into a shoe, with the container in inverted position such that the actuator is at the bottom of the container; stably resting the container in this inverted position on the inner surface of the shoe bottom; and pressing downwardly the opposite end of the container for discharging a quantity of deodorizer material into the shoe.

The invention may be embodied in different types of dispensers. For example, the container may be of the type which contains a quantity of a deodorizer material pressurized by a gas propellant, in which case the dispenser assembly would include a normally-closed valve which is opened by the actuator when pressed against the inner surface of the shoe bottom to dispense a quantity of deodorizer material via the discharge opening laterally of the dispenser assembly and into the shoe. Another type is one wherein the container contains a quantity of an unpressurized deodorizer material (liquid or powder), and the dispenser assembly includes a manual pump which is pumped by the actuator when pressed against the inner surface of the shoe bottom to dispense a quantity of the deodorizer material via the discharge opening laterally of the dispenser assembly and into the shoe.

Further features and advantages of the invention will be apparent from the description below.

DESCRIPTION OF PREFERRED EMBODIMENTS

With reference to FIG. 1 , there is illustrated a deodorizer device comprising a container 2 for containing a quantity of a liquid deodorizer material 3 . A dispenser assembly, generally designated 4 , is attached to the container 2 so as to be at the bottom of the container, rather than at the top as in a conventional dispenser of this type. Dispenser assembly 4 includes an actuator 5 in the form of a cap which is engageable with the inner surface of the bottom of the shoe, as illustrated in FIG. 2 , for dispensing the deodorizer material 3 . Dispenser assembly 4 further includes a feed tube 6 leading into the interior of container 2 , and a socket 7 in the form of a collar formed at one end of cap 5 . Socket 7 is coaxial with, and is dimensioned to receive, the external part of feed tube 6 and has one or more discharge openings 8 around its circumference. Each of the discharge openings 8 communicates via feed tube 6 with the interior of container 2 .

As shown in FIG. 1 , the opposite end 5 a of actuator cap 5 , which engages the inner surface of the shoe bottom as shown in FIG. 2 , is of large cross-sectional area, the cross-sectional area of the actuator decreasing towards collar 7 formed with one or more discharge openings 8 . Preferably, actuator cap 5 is of a generally conical configuration.

FIG. 2 illustrates the manner of using the deodorizer device for deodorizing a shoe, generally designated 10 . Thus, the deodorizer device is inserted into the shoe, with the container 2 in the illustrated inverted position so that the actuator cap 5 is at the bottom of the container, and the outer surface of end 5 a of the actuator cap 5 is pressed against the inner surface of the shoe bottom. This depression of the actuator cap 5 actuates the dispenser assembly 4 to discharge deodorizer material 3 via the discharge openings 8 around the circumference of the dispenser assembly 4 and in all directions into the interior of the shoe 10 .

As one example, the container 2 could contain a quantity of liquid deodorizer material 3 pressurized by a gas propellant; and the dispenser assembly 4 could include a normally closed valve which is opened by actuator cap 5 when pressed against the shoe bottom to dispense a quantity of the deodorizer material 3 via the discharge openings 8 around the dispenser assembly 4 and in all directions into the interior of the shoe 10 . Any known deodorizer material could be used, e.g., in the form of an anhydrous suspension, a suspension in water or some other liquid carrier, or dry powder.

As another example for implementing the invention, the container 2 could contain a quantity of an unpressurized liquid deodorizer material 3 , and the dispenser assembly 4 could include a manual pump which is pumped by actuator cap 5 when pressed against the inner surface of the shoe bottom to dispense a quantity of the deodorizer material via the discharge openings 8 .

The conical shape of actuator cap 5 provides a large surface area at its end 5 a for engagement with the shoe bottom, and a relatively smaller annular area occupied by the discharge openings 8 for discharging the deodorizer material in all directions. In addition, this configuration of the actuator enables container 2 to stably rest in the inverted position within the shoe. It will be appreciated, however, that the actuator cap 5 may take other configurations.

Following is one example of a deodorizer material formulation that can be used:

ethanol         70%
water           23.0%
preventol R80   3.2%
NP10            2%
orange terpenes 1.0%
pine oil        0.5%
perfume         0.15%
citric acid     0.1%
EDTA            0.05%

FIGS. 3-5 illustrate another deodorizer device constructed in accordance with the invention, comprising a container 12 for containing a quantity of liquid deodorizer material 13 , and a dispenser assembly 14 attached to the container 12 so as to be at the bottom of the container. Dispenser assembly 14 includes an actuator cap 15 which is also engagable with the inner surface of the bottom of the shoe for dispensing the deodorizer material 13 , and a feed tube 16 leading into the interior of container 12 . In this case, however, feed tube 16 is integrally formed with a u-shaped extension 16 a ( FIG. 4 ) such that the open end 16 b of the feed tube 16 is at the bottom of container 12 when in its inverted position to enable the container to dispense substantially all its contents when in the inverted position.

In the modification illustrated in FIGS. 3 and 4 , only a single discharge opening 18 is formed in feed tube 16 . In addition, the actuator cap 15 is in the form of a shoe. Thus, one end of the cap 15 is formed with a socket 15 a coaxial with and dimensioned for receiving the external end of feed tube 6 , and with a slot 15 b for exposing the discharge opening 18 in the feed tube. The opposite bottom end 15 c of actuator cap 15 is formed with an enlarged surface area for engaging the upper surface of the bottom of the shoe ( 10 , FIG. 2 ), when the deodorizer device is inserted in inverted position within the shoe as shown in FIG. 2 .

The bottom end 15 c of the actuator cap 15 is preferably of sufficiently large surface so as to enable the container 12 to be stably supported in inverted position in the shoe such that, whenever a quantity of deodorizer material is to be dispensed, the user may merely press the opposite end of container 13 downwardly to discharge a quantity of the deodorizent material from discharge opening 18 . Discharge opening 18 is oriented to direct the discharged deodorizer material towards the tip of the shoe cap 15 , and of the shoe being deodorized ( 10 , FIG. 2 ).

In all other respects, the deodorizer device illustrated in FIGS. 3-5 is constructed, and is used in the same manner, as described above with respect to FIGS. 1 and 2 .

FIG. 6 illustrates a further construction similar to that of FIGS. 3-5 , except that the actuator cap 25 , also in the shape of a shoe for stably resting the container 22 in an inverted vertical position, is built into the dispenser assembly 24 , rather than being constructed as a separate cap applied to the container. Another modification is that the opposite end of the container 26 is of a dome-shaped configuration, which precludes supporting the container from that end. This construction thereby directs the user to apply the container in its inverted position. It also facilitates pressing the container downwardly, while stably resting in its inverted position within the shoe, to discharge a quantity of the deodorizer material into the shoe.

While the invention has been described with respect to two preferred embodiments, it will be appreciated that these are set forth merely for purposes of example, and that many other variations, modifications and applications of the invention may be made.
