Liquid shoe polish dispenser bottles
Burt, Yukon Ave, Hawthorne, Calif. Filed 16,Ser. More particularly, the invention concerns a novel and useful liquid dispenser employing a porous applicator from which liquid may be cont-rollably dispensed by squeezing of a deformable bottle containing the liquid and carrying the applicator, the dispenser being made so as to prevent inadvertent spilling liquid shoe polish dispenser bottles liquid from the bottle through the applicator.
The invention is concerned with the problem inherent in prior liquid. The invention isalso concerned with the tendency of prior dispensers inadvertently to leak through the applicator to the exterior. Finally, there exists, particularly in'knownshoe polish dispensers, the problem of drying out of the applicator surface, causing it to become less porousyand morediificult to use properly.
Q I All of the foregoingdifliculties are eliminated in'the present improved liquid dispenserwhich comprises a deformable squeeze bottle having a reduced neck, a tubular cavity inner cap mounted on the, bottle and extending around its neck in spaced relation thereto, a. As will be brought out, the bottlepreferably has right and left hand sets of coaxial exterior threads liquid shoe polish dispenser bottles offset with respect toone another and liquid shoe polish dispenser bottles neck, so that the inner and outer caps when screwed on these threads will have the preferred relationship with respect to the bottle neck and sponge applicator previously described.
Furthermore, the bottle which is preferably made of deformable plastic has axially otfset annular shoulders in pressure sealing engagement with the annular end faces'of the inner and outer caps to establish a pressure sealing relationship preventing liquid leakage when the caps are screwed tightly on the bottle. Other objects of the invention include the provision of a conditioner sponge retained within the outer cap and in contact with the applicator protrusion, a wetting agent as for example a light oil being held in the conditioner sponge and retaining the applicator sponge end protrusion'in continuously wetted condition to prevent A 2, tent d ,2, 1.
Thus, the applicator spongeis positively prevented from being pulled out or withdrawn in wetted condition. These and other objects of the invention, as well. Liquid shoe polish dispenser bottles, thebottle' has axially offset annular shoulders 16, 17 and 18 extending in horizontal or lateral planes and respectively formed between the neck and first thread set 12, the thread sets 12 and 13, and the thread set 13 and the outwardly bulged bottle portion 19 above the taper When screwed down on the thread set 12, cap Also, interengagement of shoulder 17 and capend face 21 limits screwing ofthe cap on the bottle in the desired relation for the retention of the plastic sponge applicator 22 in the space between the inner.
While a plastic sponge applicator is described, it will be understood that other applicators may: Thus the body portion 24 of the sponge applicator is confined between the-neck 11 and the cap For positively retaining-the sponge in position there is provided a plastic or light metal retainer ring 30 having downwardly tapered teeth 31 circularly spaced for projection into the material of the sponge in a downward direction, thereby holding the sponge body'portion against endwise retraction upwardly through the cap opening The retainer ring 30 itself is held against outward retraction by the outer lip or flange 32 of the cap 20 which overlies the ring and blocks or limits its upward displacement relative to the cap.
Threaded downwardly on the outer or larger set of bottle threads 13 isanouter cap or closure liquid shoe polish dispenser bottles shown in Fig. The outer cap completely encloses the inner cap 20 and the applicator protrusion 26 and forms a pressure seal at the interengagement between the bottle shoulder 18 and the cap annular end face Such sealing engagement of both caps 20 and 33 with the bottle at shoulders 17 and 18 respectively, is best facilitated by the plastic composition of both caps and the: As is liquid shoe polish dispenser bottles in Fig.
A wetting agent held by capillary action in the porous conditioner sponge maintains the applicator sponge in continuously wetted condition keeping it suitable for instantaneous use in dispensing liquid If the sponge protrusion 26 were not wetted at all times, not only would it take longer to moisten sufliciently the applicator with the liquid 23 to the point where suitable dispensing action liquid shoe polish dispenser bottles take place, but also, the drying'out action of certain liquid shoe polish dispenser bottles of liquid 23, for example shoe polish, would cause a liquid shoe polish dispenser bottles to form on the surface of the applicator 26 decreasing the porosity of the applicator at its surface and causing it generally to be undesirable in appearance and diffieult to use, especially after repeated usage.
Suitable wetting agents hel dwithin the conditioner sponge 40 comprise lubricants such as light oils, for example neats-foot oil, mineral oil and light vegetable oils. Cap 20 liquid shoe polish dispenser bottles also be extended upwardly above flange 32 in order to form a cavity receiving all of the sponge except the tip thereof.
In use, the cavity will control flow of liquid to feed only the end area of the sponge being used to dispense the liquid, and also the cavity walls will prevent any excess accumulation of liquid from dripping off the sponge. As seen in Fig. Also, the flange 32 of the cap 20 acts to compress the reduced end portion 26 of the sponge against the terminal end liquid shoe polish dispenser bottles the bottle neck.
An improved liquid dispenser, comprising liquid shoe polish dispenser bottles deformable squeeze bottle having a reduced neck of greater wall thickness than the wall thickness of the deformable bottle, a tubular inner cap mounted on said bottle and extending around said neck and the terminal end thereof in spaced relation thereto, a porous applicator retained in the space between said inner cap and neck, said applicator having an enlarged annular portion extending about and compressed against the neck shank and a reduced end portion completely covering and compressed by the cap against the open terminal end of the neck and protruding through the cap endwise opposite the 'neck for dispensing liquid contained within the bottle, and an enlarged outer cap detachably mounted on the bottle and enclosing the inner cap and the applicator protrusion to prevent inadvertent spilling of liquid from said dispenser.
The invention as defined in claim 4' in which the bottle tapers throughout a major portion of its length liquid shoe polish dispenser bottles an axial direction extending away from said second set of threads, whereby upon manual squeezingof the bottle the liquid contents thereof are forced toward the bottle neck and the sponge applicator; a.
The invention as defined in claim 4including a conditioner sponge retained within the outer cap and in cont-act with the applicator protrusion, and an oily wetting agent held in said conditioner sponge and maintaining said applicator sponge protrusion in continuously wetted condition.
The invention liquid shoe polish dispenser bottles defined inelaim 4 including a 16 plastic retainer ring confined by said'inner cap in the space between said inner cap and bottle neck, said ring having circularly spaced teeth projecting toward the bottle and into the material liquid shoe polish dispenser bottles the applicator sponge for holding said applicator against inadvertent endwise outward withdrawal from said space.
Q I All of the foregoingdifliculties are eliminated in'the present improved liquid dispenserwhich comprises a deformable squeeze bottle having a reduced neck, a tubular cavity inner cap mounted on the, bottle and extending around its neck in spaced relation thereto, a liquid shoe polish dispenser bottles applicator retained within theinner cap and neck, the applicator covering the latter and protruding through the cap endwise opposite the neck for dispensing liquid contained within the bottle and finally an enlarged outer cap detachably mounted on the bottle and enclosing the inner cap and the applicator protrusionto prevent inadvertent spilling of liquid from the bottle through the applicator.
Thus, the caps and bottle may all be made of plastic and then there can be no inadvertent leakage of liquid from the assembled caps and bottle no matter how the bottle is oriented in storage. J Other objects of the invention include the provision of a conditioner sponge retained within the outer cap and in contact with the applicator protrusion, a wetting agent as for example a light oil being held in the conditioner sponge and retaining the applicator sponge end protrusion'in continuously wetted condition to prevent A 2, tent d ,2, 1.
