FIG. 1 is a perspective view of a cosmetic dispenser with a cap. The dispenser comprises acap 110 shown atop abody 160, with the body extending into abase shell 210. The configuration shown inFIG. 1 is a “full” configuration, in which the body is filled with a cosmetic product. The cosmetic product may be, for example, a foundation product. Other products may be provided instead including, for example and without limitation, mascara, lip gloss, eye liner, concealer, eye primer, lash primer, lip stain, nail polish, polish remover, and other products applied via brushes, sponges, or other cosmetic applicators. - As the product is used, the
body 160 can be rotated or twisted relative to thebase shell 210, expelling product as discussed below, until the configuration shown inFIG. 8 is achieved, in which thecap 110 lies more or less adjacent thebase shell 210, with thebody 160 mostly contained within the base shell. -
FIG. 2 is a perspective view as inFIG. 1 with the cap removed to illustrate the dispenser and applicator. The upper portion of the body is shown with anapplicator 130, which may be, for example, a sponge, metal, stone, ceramic, glass, a flexible or hard plastic, rubber or polymer, a gel, or a multiple piece member including for example, a metal portion and a plastic portion. A brush may be provided instead as theapplicator 130. Other parts of the body may be made of any suitable materials, such as plastic (for example, polypropylene, acrylonitrile butadiene styrene, polyoxymethylene or other plastics, preferably ones which are non-reactive with the cosmetic products to be used), glass, metal, wood, composites thereof, or any other suitable material, for containing a cosmetic, medicinal, personal care, or other product. - An
outer collar 150 is visible and is held in place by an inner collar (not shown) which attaches to the top of thebody 160 as shown below, as well as being secured to theapplicator 130 by, without limitation, snap fit, threaded attachment, press fit, heat attachment, or adhesive, for example. Again thebody 160 extends into thebase shell 210. -
FIG. 3 is an exploded view showing the parts of an illustrative dispenser.Cap 110 is actual an outer shell in this example that is fitted (press fit, snap fit and/or adhesive, for example) on aninner cap 120 which. The applicator is shown at 130 adjacent to theinner collar 140. Theinner collar 140 would be affixed to theapplicator 140 as previously explained, and also secured to thebody 160 in order to hold a decorative or protectiveouter collar 150 in place. Thebody 160 is shown in greater detail below inFIG. 4 . Apiston 170 is also provided and secures to apiston holder 180. Aplug 190 is provided to secure inside thepiston holder 180; in some examples, theplug 190 may be integral with thepiston holder 180 instead. Thebase shell 210 fits around areceiver 200. - The
receiver 200, as shown and explained further below, is adapted to mate with and be secured to thepiston holder 180 and includes a structure on an inner face thereof, such as threads, that engage with corresponding structure on the lower portion of thebody 160. A twisting motion between thebody 160 and thereceiver 200 is translated to axial motion of thebody 160 relative to thepiston 170, as further explained below, in order to expel product from a chamber within thebody 160. -
FIG. 4 shows a body for containing product in isolation. Thebody 160 includes a neck at 162 which defines aproduct passageway 162A through its interior and has an outer facingengagement structure 162B, shown here as threading, for securing a product applicator over the neck. The outer facingengagement structure 162B may operate to directly attach to a product applicator or may be for holding a collar or ferrule for a product applicator. A snap fit may be used instead of threading by providing a ring over which a snap fitting collar or the like may be placed and secured. In some examples, the outer facingengagement structure 162B may be omitted and a product applicator secured, for example, by adhesive or by having a neck of its own that can insert into theproduct delivery passageway 162A. - A cap receiving region is shown at 164 and may include structure(s) to aid in holding a cap on top of the
body 160 such as, for example and without limitation, threading, a snap ring, indentations, or protrusions, such asprotrusion 164A. A main portion of the body is shown at 166 and defines an interior chamber for holding a cosmetic product. While the top end of the main portion is closed as shown, the lower end (not shown) is generally open. The lower end of the body includes an actuating structure as shown at 168. Theactuating structure 168 is shown as threading that extends generally all the way around thebody 160; a lesser portion of the circumference may include the threading if desired. -
FIG. 5 shows a piston and piston holder. The piston is shown at 170 and includes abody 172 that secures by snap fit onto thepiston holder 180. Adhesive, screw fit, press fit, or other manners of securing thepiston 170 to thepiston holder 180 may be used in addition or instead. The piston includes a through passageway as shown at 174. In use, the through passageway may be used to allow filling at the end of manufacturing before a plug (shown inFIG. 6 ) is inserted. In an alternative embodiment, thepassageway 174 may be omitted and the device is instead configured to be assembled with a body that is preloaded with product. - The outer portion of the piston includes a sealing member as shown at 176. A sealing member may be an elastomer, rubber, cork, or various plastics/polymers that allow for sealing (and which are compatible with) the product to be dispensed relative to a surface. In some embodiments, the outer profile of the sealing
member 176 is circular or oval; other shapes may be used instead, though for ease of manufacture to yield a good seal, circular or oval are generally simpler. The sealingmember 176 is sized and shaped to match an inner profile of the body (seeFIG. 6 ). - The
piston 170 is held in place by apiston holder 180. The base of thepiston holder 180 comprises, optionally,teeth 182, which are used to engage with a receiver (seeFIG. 6 ) to prevent rotation therebetween. A polygonal shape may be used instead ofteeth 182. A securing structure is shown at 184 for securing to the receiver (seeFIG. 6 ) to prevent axial motion between the receiver and thepiston holder 180. - In some examples, the
piston 170 is designed to be secured such that is cannot rotate relative to thepiston holder 180. In other examples, particularly where the sealing member is non-circular, the piston holder and piston may allow rotation of the piston relative to the piston holder. In further embodiments, thepiston holder 180 may omit theteeth 182 and/or polygon and allow thepiston holder 180 to rotate relative to the receiver, if desired. -
FIG. 6 shows a cross section of a cosmetic dispenser with applicator and cap in an extended form for when the body thereof is full of cosmetic product. Beginning at the top of the Figure, the cap shell is shown at 110 and is a thin piece provided largely for decorative and/or protective purposes, and which may be made of a metal or hard plastic, for example. Thecap shell 110 is secured over aninner cap 120 which may include a structure as shown at 122 that is adapted to enter and generally seal shut the upper end of theproduct delivery passageway 162A through theneck 162 of thebody 160.Element 122 may be referred to as a pintle, in that it is generally pin-like. In the example shown, thepintle 122 extends through the entire thickness of theproduct applicator 130. Apintle 122 may be omitted in other examples. Theinner cap 120 may be made for example of any suitable polymer. - The
product applicator 130 is seated using, for example, press fit, snap fit, threading, or adhesive, or other securing method, to aninner collar 140. A decorative and/or protective outer collar is provided as shown at 150 (more easily seen in earlier Figures). Theinner collar 140 is secured to the outer facing engagingstructure 162B and may be snap fit, press fit, and/or adhesively secured to theouter collar 150; or, alternatively, theouter collar 150 may simply be held in place by the inner collar being secured to structure 162B. - The overall applicator structure may include the actual applicator 130 (which may be any of various actual structures as noted above, such as a sponge, metal or gel), the
inner collar 140 and theouter collar 150. - The
body 160 defines achamber 166 for receiving a cosmetic product. The lower portion of thebody 160 includes theactuating structure 168 which is shown as being coupled to the engagingstructure 202 of thereceiver 200. Here, the engagingstructure 202 is shown as threading that extends for most of the length of the interior of thereceiver 200. Twisting thereceiver 200 relative to thebody 160 will, by action of theactuating structure 168 interacting with the engagingstructure 202, cause thebody 160 to be drawn into thereceiver 200. - The
receiver 200 is secured to thepiston holder 180 in two ways. For prevention of axial motion of thereceiver 200 relative to thepiston holder 180, the snapfit ring 184 of the piston holder is engaged with aninterior collar 204 of thereceiver 200. In addition, though not shown, the teeth of thepiston holder 180 mate with corresponding teeth of thereceiver 200, preventing rotational motion therebetween. Thereceiver 200 sits within thebase shell 210, to which it may be snap fit, press fit, or adhered. - The
piston 170 is held in place on top of thepiston holder 180 and resides, as shown here, into the lower portion of thechamber 166 of thebody 160. The sealingmember 176 rests flexibly against the inner wall of thebody 160, as shown, creating a seal. Aplug 190 is shown and may include anupper end 192 adjacent to the through hole of thepiston 170. Theplug 190 may be snap fit, press fit, and/or heat or chemically adhered into place. In the illustrative example, theplug 190 snap fits as shown at 192 to thepiston holder 180. - Thus, as shown here, the
body 160 is coupled to thereceiver 200 and thepiston holder 180 andpiston 170 are coupled to thereceiver 200 such that twisting of thebody 160 relative to thereceiver 200 causes axial motion of thepiston 170 within thebody 160 due to interaction of theactuating structure 168 of the body with the engagingstructure 202 of thereceiver 200, thereby dispensing product from thebody 160 via theproduct passageway 162A. Such twisting motion will draw thebody 160 into thereceiver 200 until the product is entirely dispensed, achieving a configuration as shown inFIG. 7 . - It may be noted that the
actuating structure 168 of thebody 160 may have a structure other than threads. For example and without limitation, tabs or posts adapted to engage a threaded structure of thereceiver 200 may be provided instead. In the example shown, theactuating structure 168 traverses a small fraction of the length of thebody 160 in order to provide a smooth exterior; as a result, the engagement structure (here, threading 202) in thereceiver 200 extends most of the length of thereceiver 200. In an alternative, thebody 160 may have threading over almost all of its length, providing a different look and feel from an aesthetic perspective, while thereceiver 200 includes a shorter portion of threading 202 or includes tabs or posts instead. -
FIG. 7 shows a cross section of a cosmetic dispenser in retracted form for when the body has been emptied of product. In this Figure, the cap and applicator structures have been omitted to allow easier viewing of the rest of the device; it should be understood that in use such elements would be present. Here, theactuating structure 168 of thebody 160 has traversed the length of the engagingstructure 202 of thereceiver 200, until reaching the base or stop of thereceiver 200, as shown at 208. During this process, thepiston holder 180, being secured to thereceiver 200 as shown at 184, advances thepiston 170 axially into the product holding chamber of thebody 160. -
FIG. 8 is a side elevation view of a cosmetic dispenser with a cap. Here, all the product has been expelled from the device as indicated by thecap shell 110 now being adjacent to thebase shell 210, with the body no longer visible. This end point is merely illustrative; the body could still be visible in other embodiments. - Each of these non-limiting examples can stand on its own, or can be combined in various permutations or combinations with one or more of the other examples.
- The above detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the invention can be practiced. These embodiments are also referred to herein as “examples.” Such examples can include elements in addition to those shown or described. However, the present inventors also contemplate examples in which only those elements shown or described are provided. Moreover, the present inventors also contemplate examples using any combination or permutation of those elements shown or described (or one or more aspects thereof), either with respect to a particular example (or one or more aspects thereof), or with respect to other examples (or one or more aspects thereof) shown or described herein.
- In the event of inconsistent usages between this document and any documents so incorporated by reference, the usage in this document controls. In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. The above description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more aspects thereof) may be used in combination with each other. Other embodiments can be used, such as by one of ordinary skill in the art upon reviewing the above description.
- The Abstract is provided to comply with 37 C.F.R. § 1.72(b), to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
- Also, in the above Detailed Description, various features may be grouped together to streamline the disclosure.
