The present invention relates generally to dispensers for fluid materials, such as cosmetics. More particularly, disclosed and protected hereby is an extendable and retractable dispenser with distal and lateral wiping for facilitating proper applicator loading and improved applicator performance.
Cosmetic dispensers for mascara and other liquid or pasty cosmetics commonly comprise two-piece assemblies, namely a container and a cap. The container has an open inner volume for retaining a volume of the cosmetic, and the cap has a wand projecting therefrom with a brush or other structure for being dipped in the cosmetic. When dipped in the cosmetic, the brush becomes loaded with the liquid or pasty cosmetic material for application. By a threaded engagement between the cap and a neck of the container, the cosmetic dispenser can be sealed during periods of nonuse.
During cosmetic application, therefore, a user will normally retain the cap in one hand and the applicator in the other to enable repeated dipping and, consequently, the successful application of the cosmetic. However, occupying both hands with the application of the cosmetic is awkward and leaves the user substantially unable to carry out other functions, such as holding a mirror or another cosmetic article. Mascara is commonly applied in such a manner as are other liquid, semi-liquid, pasty or related cosmetics, including lip gloss, concealer, eye shadow, and further cosmetics.
It has thus been a longfelt need in the cosmetics industry to provide a cosmetic dispenser that can be reliably operated with a single hand. Advantageously, a number of skilled inventors have attempted to devise cosmetic operators capable of one-handed operation. However, as the dearth of such devices on the commercial market demonstrates, the creation of a commercially viable structure has thus far not been achieved.
For example, in U.S. Patent Application Publication No. 2004/018865, Carroll discloses a retractable cosmetic applicator that is designed to be capless. The applicator passes from a refracted position to an extended position through an aperture with a front cowling and a valve. The valve is said to substantially seal the aperture when the applicator is in a retracted position thereby eliminating a need for a cap. With that, one handed operation of the device is said to be possible. However, it does not appear that any accommodation is made to address the buildup of backwiped product on and around the aperture as the applicator is extended and retracted. Furthermore, the spring-loaded structure appears to be relatively complex in structure and operation thereby increasing the likely overall cost of manufacture and resultantly increasing the ultimate price that must be paid by the end consumer.
A further longstanding difficulty that many prior art inventors have sought to confront is the proper loading of cosmetic onto the applicator since that proper loading is critical to the efficient application of cosmetics. A related problem known to the art is the undesired buildup of cosmetic material on the tip and body of the dispenser, the rim of the container, and elsewhere, particularly after repeated applications. There has, therefore, been a longfelt need for a cosmetic dispenser that ensures proper loading of the applicator while avoiding unwanted buildup, preferably with excess cosmetic material being returned to the open inner volume of the container.
Notwithstanding the appreciation of such difficulties and needs, inventors of the prior art have been unable to provide an effective and elegant solution to the same. For example, U.S. Pat. No. 4,671,689 to Gueret is directed to a makeup unit wherein a cosmetic applicator is retained relative to a cap. A laterally communicating wiper has a plurality of slits communicating radially from an open center portion. With this, the wiper provides a wiping of the side of the cosmetic applicator as it is pulled from within the bottle. However, it would appear that the distal end of the cosmetic applicator would not be automatically wiped whereby the problems of tailing and mascara buildup at the distal end of the cosmetic applicator are not remedied.
For these and further reasons, cosmetic dispensers of the prior art are often messy and inefficient in use. For example, a common problem experienced by users of current mascara dispensers is known as “tailing” where a tail of mascara is left on the distal end of the applicator, such as at the tip of the applicator brush in a mascara applicator. Since the dispensers typically employ a wiper that is generally sized to the diameter of the plastic portion of the applicator wand, the wiper does not engage the “tail” of mascara even as the brush passes through the wiper. As a result, a small blob of mascara is left at the end of the brush. This small blob of mascara can fall from the brush or be undesirably applied to the skin or hair of the user. While experienced mascara users often wipe the end of the brush on the inner portion of the lip of the mascara container, the wiped blob can contribute to increased buildup on and around the rim of the dispenser, on the mascara wand, and elsewhere thereby increasing messiness and waste.
In light of the foregoing, it will be appreciated that there is a need in the art for a cosmetic dispenser that overcomes the disadvantages common to prior art dispensers while permitting efficient one-handed operation in the application of cosmetics.
Advantageously, the present invention is founded on the basic object of providing a cosmetic dispenser that can be operated effectively with a single hand.
Another object of embodiments of the invention is to provide a cosmetic dispenser that can be extended and retracted between storage and use positions.
A further object of embodiments of the invention is to provide a cosmetic dispenser that ensures a proper loading of liquid or pasty cosmetics.
An even further object of embodiments of the invention is to reduce or eliminate tailing from the tip of the dispenser.
Embodiments of the invention have the still further objects of minimizing mess and preventing waste.
These and further objects and advantages of embodiments of the invention will become obvious not only to one who reviews the present specification and drawings but also to one who has an opportunity to make use of an embodiment of the instant invention for a cosmetic dispenser disclosed herein. The accomplishment of each of the foregoing and possibly further objects in a single embodiment of the invention may be possible and indeed preferred. However, it will be appreciated that not all embodiments will seek or need to accomplish each and every potential object and advantage. Nonetheless, all such embodiments should be considered within the scope of the present invention.
In carrying forth the aforementioned and further objects, a basic embodiment of the cosmetic dispenser disclosed herein is founded on a bottle with an open inner volume, a closed proximal end, and a distal end with an aperture. An applicator wand is retained for slidable extension and retraction relative to the bottle. A base member, which can comprise a base cup, is fixed to a proximal end of the applicator wand, and a cosmetic applicator, such as a brush or other means, is retained by the distal end of the applicator wand. A longitudinal slide channel in combination with a slide member, such as a slide button, operate as a means for enabling a selective sliding of the applicator wand from a refracted position wherein the cosmetic applicator is retained within the open inner volume of the bottle and an extended position wherein the cosmetic applicator projects through the aperture at the distal end of the bottle. The open inner volume of the bottle is divided into a distal open inner volume to a distal side of a lateral dividing structure and a proximal open inner volume to a proximal side of the lateral dividing structure. The distal open inner volume is in fluidic communication with the aperture in the distal end of the bottle but is fluidically sealed in relation to the proximal open inner volume. An aperture in the dividing structured slidably receives the applicator wand to permit the cosmetic applicator to be extended and retracted.
In certain embodiments, the slide member can be engaged with the applicator wand by at least one leg with a first end fixed to the slide member and a second end engaged with the base member that is fixed to the proximal end of the applicator wand. Further, the lateral dividing structure can be formed by an adapter insert with a base and a peripheral wall. The aperture in the lateral dividing structure can then be in the base concentric with the bottle, and the peripheral wall can have a size and shape corresponding to a size and shape of an inner wall surface of the bottle.
Embodiments of the cosmetic dispenser can have a body portion that is formed by a base shell with a closed proximal end and an open distal end and a bottle sleeve with an open proximal end for engaging the open distal end of the base shell. Under such constructions, the adapter insert can have a peripheral rim that overlies the distal end of the base shell. Furthermore, the lateral dividing structure can additionally include a rear seal with a peripheral wall and a base with a through-hole that slidably receives the applicator wand. Where the adapter insert and the rear seal can be matingly engaged, and the bases of the rear seal and the adapter insert are disposed proximal to the peripheral walls of the rear seal and the adapter insert. So disposed, the peripheral walls and the base portions cooperate to define a reception well into which the cosmetic applicator can be dipped.
In particular manifestations of the cosmetic dispenser, a laterally disposed distal wiping wiper can be included. The distal wiping wiper can have a bottom wall that communicates laterally across the open inner volume of the bottle distal to the cosmetic applicator and the applicator wand when the applicator wand is in a retracted position. A plurality of radial slits can be disposed in the bottom wall for permitting a passage of the cosmetic applicator through the distal wiping wiper and for enabling a wiping of a distal end of the cosmetic applicator.
Still further, a side wiping wiper can be disposed within the bottle for wiping cosmetic material from peripheral portions of the cosmetic applicator. The side wiping wiper can have a longitudinal annular inner wall portion adjacent to a distal end thereof and a frusto-conical inner portion that narrows to an annular inner throat, and the side wiping wiper can be disposed distal to the distal wiping wiper within the bottle. With such a side wiping wiper, a cap can be employed for sealing the distal open inner volume of the bottle, and the cap can have a concentric plug that projects proximally to mate with the side wiping wiper. More particularly, the plug of the cap can have a tip for being received within the throat of the side wiping wiper and a frusto-conical portion corresponding to the frusto-conical inner portion of the side wiping wiper to ensure that residual cosmetic material is returned to the open inner volume of the bottle.
One will appreciate that the foregoing discussion broadly outlines the more important features of the invention to enable a better understanding of the detailed description that follows and to instill a better appreciation of the inventors' contribution to the art. Before any particular embodiment or aspect thereof is explained in detail, it must be made clear that the following details of construction and illustrations of inventive concepts are mere examples of the many possible manifestations of the invention.
In the accompanying drawing figures:
It will be appreciated that the cosmetic dispenser disclosed herein is subject to widely varied embodiments. However, to ensure that one skilled in the art will be able to understand and, in appropriate cases, practice the present invention, certain preferred embodiments of the broader invention revealed herein are described below and shown in the accompanying drawing figures.
Looking first to the cross-sectional views of
As shown in
The receiving portion 44 of the bottle sleeve 14 can be dimensioned to receive the neck 36 of the base shell 12, and the peripheral ridge 38 can be dimensioned to engage the peripheral channel 46. Under this arrangement, the base shell 12 can be engaged with the bottle sleeve 14 by an insertion of the neck 36 of the base shell 12 into the receiving portion 44 until the peripheral ridge 38 engages the peripheral channel 46. With that, the base shell 12 and the bottle sleeve 14 are secured together.
An applicator wand 16 with a proximal end fixed to a base cup 18 that acts as a base member and a distal end for retaining a cosmetic applicator, such as a mascara brush or other means, is retained for slidable extension and refraction relative to the base shell 12 and the bottle sleeve 14. The applicator wand 16 and the base cup 18 are shown alone in
The base shell 12 has a slide channel 22 that communicates longitudinally therealong, and the base cup 18 has a rectangular fastening aperture 48 in the outer wall thereof disposed to align with the slide channel 22. With this, a slide button 20 that acts as a slide member can engage the base cup 18 through the slide channel 22 to enable a user to extend and retract the base cup 18, the applicator wand 16, and any cosmetic applicator retained relative thereto by a selective sliding of the slide button 20. The slide button 20 can have an engaging portion for engaging a user's finger and first and second opposed, resiliently deflectable legs with outwardly disposed, distal protuberances whereby the legs can pass through the slide channel 22 and snap engage the wall of the base cup 18 through the fastening aperture 48,
The alignment of the applicator wand 16 and a retained applicator 15 can be ensured by an adapter insert 26, which is shown apart in
With this, the base portion and the outer wall of the adapter insert 26 can be received in the second end of the bottle sleeve 14 while the peripheral rim 50 overlies that second end of the base shell 12. The adapter insert 26 can thereby effectively plug the second end of the base shell 12 while being retained securely in place with the peripheral rim 50 sandwiched, together with the peripheral rim 54 of the rear seal 28 described below, between the distal end of the neck 36 of the base shell 12 and the shoulder 45 of the bottle sleeve 14.
The adapter insert 26 can be formed from any suitable material, preferably a material demonstrating sufficient rigidity and durability to provide support to the applicator wand 16. In one presently contemplated embodiment, the adapter insert 26 can be crafted of high-density polyethylene (HDPE). Of course, other means for maintaining the alignment of the applicator wand 16 and the retained applicator 15, whether it be a brush, fingers, or any other type of applicator 15, are possible and within the scope of the invention.
The first end of the bottle sleeve 14 can be effectively sealed in relation to the base shell 12 by a rear seal 28 together with the applicator wand 16 that is slidably received through a concentric through-hole 56 in the base of the rear seal 28. Similar to the adapter insert 26, the rear seal 28 has an outer wall with an oval cross section and a peripheral rim 54 greater in lateral dimensions than the corresponding inner dimensions of the base shell 12. The through-hole 56 can be dimensioned to have a diameter close to the diameter of the applicator wand 16, whether it be slightly less than, slightly greater than, or generally equal to the diameter of the applicator wand 16.
With this, in addition to sealing the first end of the bottle sleeve 14 to define a substantially liquid-tight open inner volume, the rear seal 28 can clean liquid or pasty cosmetic material from the applicator wand 16 as it is retracted into the base shell 12 by operation of the slide button 20. To facilitate the wiping of the pasty cosmetic material and the effective sealing of the open inner volume, the rear seal 28 can be formed from a durable yet pliable material. In one preferred example, the rear seal 28 can be formed from a thermoplastic elastomer (TPE) and can preferably have a hardness in the range of Shore 46 D.
The rear seal 28 can be disposed in opposition to the adapter insert 26 not shown) or seated within the adapter insert 26 as in
In either case, the rear seal 28 can render the first end of the bottle sleeve 14 liquid tight while allowing the applicator wand 16 to slide therethrough. Together with the adapter insert 26, the rear seal 28 can be securely retained in place with its peripheral rim 54 sandwiched between the distal end of the neck 36 of the base shell 12 and the shoulder 45 of the bottle sleeve 14. Where the rear seal 28 is seated within the adapter insert 26 as in
What can be referred to as a distal wiping, laterally disposed wiper 30, which is shown apart in
So disposed, the wiper 30 presents a substantially continuous surface when not-deflected to substantially seal the open inner volume of the bottle sleeve 14 while allowing the cosmetic applicator 15 to pass therethrough when the applicator wand 16 is extended. Advantageously, in addition to providing some wiping of the lateral surfaces of the cosmetic applicator 15, the wiper 30 will wipe any accumulation of cosmetic that is disposed at the tip of the applicator 15 thereby preventing tailing and the waste, messiness, and other deleterious results thereof.
The cosmetic dispenser 10 additionally incorporates what can be referred to as a side wiping wiper 32 that in this case is retained within the neck 40 of the bottle sleeve 14 distal to the distal wiping, laterally disposed wiper 30. With further reference to
The wiper 32 has a longitudinally communicating annular inner wall portion 66 adjacent to the distal end thereof and a frusto-conical inner portion 68 that narrows to an annular inner throat 70. The throat 70 is dimensioned for close engagement with the cosmetic applicator 15 and the applicator wand 16. Under this arrangement, after having its distal end wiped by the distal wiping, laterally disposed wiper 30, the cosmetic applicator 15 and then the applicator wand 16 can slide through the side wiping wiper 32. The throat 70 will wipe the cosmetic liquid or paste from the cosmetic applicator 15 and the wand 16 thereby to ensure proper loading of the applicator 15 for optimal makeup application and to ensure efficient product usage and a reduced potential for mess. The wiper 32 can be formed from any suitable material. In one preferred embodiment, low density polyethylene is preferable.
With combined reference to
It will be appreciated, of course, that the shapes and configurations of the various components of the cosmetic dispenser 10 could vary within the scope of the invention. For example, although the base shell 12 and the bottle sleeve 14 are shown as oval in cross section, round, rectangular, and otherwise shaped structures could readily be constructed based on this disclosure. Similarly, while components such as the applicator wand 16, the through-hole 55 in the seal 28, and the inner surface of the wiper 32 are depicted as having annular cross sections, it would be within the scope of the invention, except as explicitly limited, for those components to pursue non-circular cross sections, whether oval, square, or some other shape.
The disclosed cosmetic dispenser 10 overcomes many of the disadvantages of the prior art while providing useful advantages thereover. For example, extension and retraction of the applicator 15 and the applicator wand 16 by use of the slide button 20 enables effective one-handed operation of the cosmetic dispenser 10. With the distal and side wiping provided by the distal wiping wiper 30 and the side wiping wiper 32, the cosmetic dispenser 10 ensures proper loading of the applicator 15 while reducing the inconvenience and mess that can derive from improper loading, tailing, and the like. Still further, with the reception well defined by the bottle sleeve 14 and the rear seal 28, the cosmetic dispenser 10 can reduce waste by permitting usage of a greater percentage of retained cosmetic material.
With certain details of the present invention for a cosmetic dispenser 10 disclosed, it will be appreciated by one skilled in the art that changes and additions could be made thereto without deviating from the spirit or scope of the invention. This is particularly true when one bears in mind that the presently preferred embodiments merely exemplify the broader invention revealed herein. Accordingly, it will be clear that those with certain major features of the invention in mind could craft embodiments that incorporate those major features while not incorporating all of the features included in the preferred embodiments.
Therefore, the following claims are intended to define the scope of protection to be afforded to the inventors. Those claims shall be deemed to include equivalent constructions insofar as they do not depart from the spirit and scope of the invention. It must be further noted that a plurality of the following claims may express certain elements as means for performing a specific function, at times without the recital of structure or material. As the law demands, these claims shall be construed to cover not only the corresponding structure and material expressly described in this specification but also all equivalents thereof that might be now known or hereafter discovered.
