All-plastic, fragrance bottle refill mechanism

Abstract

A closure cap is structured to carry and contain a granular or powdered solid substance. The cap includes a rotating sleeve that pierces a containment membrane, such as a foil seal, so as to release the solid substance into liquid container sealed by the cap. Significantly, this releasing action occurs through the natural rotation of the cap relative to the bottle, thereby providing the user with a familiar mechanism and without the need to separately measure or transfer the solid into the liquid.

Description

TITLEALL-PLASTIC, FRAGRANCE BOTTLE REFILL MECHANISMCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to United States provisional patent application serial number 63 / 565,609, filed on March 15, 2024, which is incorporated by reference herein.FIELD OF THE INVENTION

[0002] This invention relates to a mechanism useful for refilling containers with consumable liquids and, more specifically, to a universal screw cap closure attached to a stock bottle capable of dispensing fluid into — while also simultaneously accepting make-up air from — a bottle pressed against the dispenser facing of the closure.BACKGROUND

[0003] A number of proposals exist for refilling consumer-oriented containers. Generally speaking, these consumer-oriented containers have a removable cap. The open container neck of that container is placed into contact with a refill vessel having a refill closure affixed to it, thereby allowing for the transfer of fluids from the refill vessel into the container (after which the removable cap is replaced, so as to allow continued use of that now-filled container).

[0004] International patent publication W02023 / 086608A1 describes a closure system including a funnel with threads and seal beads that is received in the open ned of a closure skirt. Thereafter, refill product may be freely poured into the funnel to refill the container. Similar refill systems can be seen in international patent publication WO2022 / 177936A1 and Japanese patent publication JP2018 / 203312A. One disadvantage of these systems is the need to pour a free flowing fluid through an open funnel, as this can lead to accidental spills and loss of the fluid.

[0005] Other specialized refill systems can be seen in United States patent publication 2005 / 0205151A1 and United States Patents 7,753,087; 8,899,498; and 9,085,397. Generally speaking, many of these mechanisms rely on rotational movement to open or close various components in the refill valve. Many also require the container being filled to be screw fitted onto the valve / mechanism, which requires additional time and effort.

[0006] A final style of refill systems rely on separate ports or openings in the container, such as those seen in United States patent 9,409,761. A major disadvantage of such systems is the fact they often position the refill port at an opposite end of the container from where the dispensing closure is attached, thereby requiring specialized containers to be employed on the consumer side (in addition to the refill vessel).

[0007] All of the foregoing disclosures are incorporated by reference as if fully reproduced herein. These disclosures may inform and supplement this disclosure with respect to materials selection, construction, component design, and various other aspects of this disclosure and any claims based thereon.

[0008] Given the above, there remains a need for an easy-to-use refill system and apparatus that does not require funnels, open pouring of the contents, specialized consumer-use bottles, and / or elaborate or time-consuming connection techniques.SUMMARY OF INVENTION

[0009] The invention includes a system that is attachable to a standardized refill vessel by way of a connector including a closure, a piston, and a movable valve. A refillable container (typically, a end use / consumer package) is pressed up against the piston so as to allow the gravity -assisted flow of fluid into the product while simultaneously allowing air in the refillable container to be evacuated into the refill vessel. A peripheral locking system on the piston provides an option for the refillable container to be locked into place, as well as to simplify the alignment of the components from an open to closed position (or vice versa).

[0010] Still other aspects and advantages of the invention can be discerned upon careful study of the description and drawings appended hereto. Accordingly, nothing in this summary (or elsewhere in this specification) should be interpreted as a limitation or disclaimer of these aspects and advantages, unless it is expressly phrased as such.BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Operation of the invention may be better understood by reference to the detailed description, draw ings, claims, and abstract — all of which form part of this written disclosure. While specific aspects and embodiments are contemplated, it will be understood that persons of skill in this field w ill be able to adapt and / or substitute certain teachings without departing from the underlying invention. Consequently, this disclosure should not be read as unduly limiting the invention(s).

[0024] As used herein, the words ‘’example” and “exemplary” mean an instance, or illustration. The words “example” or “exemplary'” do not indicate a key or preferred aspect or embodiment. The word “or” is intended to be inclusive rather an exclusive, unless context suggests otherwise. As an example, the phrase “A employs B or C,” includes any inclusive permutation (e.g., A employs B; A employs C; or A employs both B and C). As another matter, the articles “a” and “an” are generally intended to mean “one or more” unless context suggest otherwise.

[0025] Understanding that many of the components described below possess an annular and / or tubular shape in which a central aperture is surrounded by cylindrical walls and other structures, the axis and axial direction of the components will align along a line / axis that runs through the central lumen (and coincides with the anticipated direction of fluid flow passingtherethrough). Any reference to a lumen will be understood to involve a hollow tube in which the lumen is defined at least partially by the inner surfaces of that hollow tube.

[0026] Notably this central axis also aligns with the top and bottom of the page in the drawings, and the terms axial, vertical, top / bottom, or up / down may be used synonymously. In the same manner, radial or transverse directions or features in the drawings will run orthogonally to the central axis, so that references to radial, transverse, horizontal, or left / right may be used interchangeably.

[0027] It will also be understood that any cross sectional or regular three dimensional views in the drawings are intended to encompass the comparative order and arrangement of the components depicted, so that the positioning of a portion of one component above or coaxially inside / around a second component should be interpreted as being disclosed and embraced by this written description. In all such instances, the terms and directions should be read in the context of the broader disclosure and with respect to the known and anticipated uses of the components being described.

[0028] With reference to Figs. 1 -10D, the inventive system 1 includes a movable valve 2, a piston 3, and a closure 4. A gasket 5 can be seated in the closure to facilitate sealing to the refill vessel 6, and a similar approach can be employed (but is not required) at the anticipated connection point for the refillable container (not shown). Generally speaking, the system provides for a long-term connection to a refill vessel, possibly by w ay of screw -threads or other similar connection methods. The components define separate flow paths so that the refill fluid flows in one direction (e.g.. gravity fed and downward) while a return or make-up fluid (e.g., air flowing upward) passes in the opposing direction, although it is possible to reverse these arrangements and / or to rely on different fluids for filling and retum / make-up purposes. The refill container is pushed axially along a facing of the piston, so as to provide force that urges the movable valve into an open position (e.g., see Figs. 6A, 6B. and 7B) to initiate fluid flow(i.e., refilling of the container). Gravity, a biasing mechanism, or a counter force applied by the user can return the system to its closed position (e.g., see Figs. 5A, 5B, and 7B).

[0029] Along the bottom facing (see Figs. 3A and 3B), an arc- or C-shaped outer refill fluid passage is positioned around a central return fluid passage is positioned at or near the axial centreline of the piston element, which generally interfaces with the refillable container. Along a circumference at or near the periphery, a series of connection apertures provides access to locking mechanisms on the closure. A shroud or extension tube extends further downward from the inlet for the return fluid so as to minimize or avoid unwanted mixing of the fluid flows (i.e., refill vs. return or, in one embodiment, refill liquid vs. make-up air).

[0030] At the top facing (see Figs. 4A and 4B), the top end of the movable valve protrudes upward so as deliver return fluid into the refill vessel at a separate point from the refill fluid’s passage, again to minimize or avoid unwanted mixing. Here, the closure element dominates and interfaces with the refill vessel. Screw threads allow for the system 1 to be removably attached to the refill vessel for extended periods of time, preferably in an inverted position to facilitate the gravity-driven feed of refill fluid from the vessel to the container (whilst air or a less dense return or make up fluid flows in the opposite direction). In this manner, pressure differentials between the refill vessel and any given refill container can be avoided. Also, in addition to the connection threads, ratchet teeth or ribs (configured to cooperate with corresponding formations on the refill vessel) can provide further resistance to rotation or unwanted movement from and between the various components as may be required.

[0031] The valve 2 consists of a hollow tubular body 20. The end 21 is disposed toward the refill container is closed, but includes radial ports 22 in communication with the central lumen 23. A ramped protrusion 24 is interrupted by cutouts 25, preferably situated immediately below or near the ports 22. In this manner, the ramped protrusion 24 serves as a stopper that limits the axial movement and sliding of the valve 2 relative to the piston 3 and closure 4, while thecutouts 25 insure return fluid can pass around the outside of the end 21 and up / axially along the exterior of the valve 2 in order to enter the lumen 23 through the ports 22.

[0032] The end 22 is open and disposed within the refill vessel 6 when the system 1 is installed. Thus, when the system 1 and, more specifically, valve 2 are in the open position, return fluid passes in a first (usually upward) direction through the system 1 to transfer return fluid from the container to the vessel 6. The return fluid may be of a lesser density7than the refill fluid, although the introduction of refill fluid into the refill container may encourage the flow of return fluid as noted above.

[0033] An expanded radial section 26, possibly in the form of a thicker wall section (in comparison to end 21) characterizes the portion of valve 2 closest to the end 22. A wiper element 27 has a frusto-conical or angled surface 271 that is configured to slide along and seal to portions of the closure 4. A radial step 272 provides an engagement surface so that interfacing portions of the piston 3 can slide the valve 2 upward and / or axially away from the refill container (and toward the vessel 6), thereby opening a flow path for refill fluid, as will be described below.

[0034] The expanded section 26 may also serve as a second limit or stopper that is axially spaced apart from the ramped protrusion 24. Collectively, the positioning and configuration of these elements will define the axial range of movement the valve 2 may travel relative to the piston 3. This spacing / distance should be sufficient to allow for return fluid to move through the system as contemplated, described, and depicted herein. The exterior shape of the ramped protrusion 24 should also facilitate its snap-fitting, coaxial installation into the lumen 31a of the piston 3. including over its inner catch protrusion 312 and inner sealing bead 315, both of which engage the valve 2.

[0035] The piston 3 has a T- or cross-like shape along a diameter of its main body 30. A disk member 32 projects radially outward along the midpoint of the body 30, with the inner fluiddeliver^' section 31 defining a lumen 31a running from tubular projection 311 to the outer fluid deliver)' section 33. Member 32 serves several functions: i) as a structural (but movable connection to the closure 4; ii) as an inner conduit to supply the flow of refill fluid to the refill container; and iii) as an interface with the refill container. Fluid deliver)' section 33 extends from an opposite facing of the disk 32 in comparison to the tubular extension 311 that defines the portion of the central passage 31. The preferably tapered edge 314 of the extension tube 311 is configured to engage the radial step 272.

[0036] The disk member 32 includes a skirt 34 positioned at its periphery. The skirt 34 has an annular wall 341 with one or a series of inward projections 342 at its upper edge that serve as limits or stoppers to maintain connection to the closure 4. Separate radial connectors 343 attach the skirt 34 and the wall 341 to the disk member 32. Ramps or formations 344 on the connectors 343, configured to cooperate with corresponding features on the closure, form part of the locking mechanism between the piston 3 and the closure 4. Specifically, ramps 344 can serve as catch mechanisms to restrain a catch ramp 4233 formed on a lower facing of circumferential extensions 4232 provided in the locking skirt 42 of closure 4.

[0037] Connectors 343 extend radially away from a blocking floor 321. Floor 321 may be orthogonal to the axis of the central passage 31, or it may have a sloped or funnel-like shape as shown in the figures. Floor 321 directs refill fluid toward the aperture 323 that allows flow through the delivery section 33 and into the refill container. One or a plurality of positioning fins 322 support the extension 311 and help to guide the along the inner extension tube 41 of the closure 4. Depending upon their rotational positioning (and understanding that piston 3 may rotate relative to closure 4 so as to engage or disengage the locking mechanism), the fins 322 may engage the piston to exert force to open the valve 2 and / or they can be received within an appropriate slot or abutment formed on / in the tube 41. In the depicted aspect, one of the fins322 may also divide the flow path by spanning across aperture 323.

[0038] The return fluid delivery section 33 has an axial tube section 332 extending further down and away from a wider, shorter tube section 313. The tube sections 313, 332 define a series of coaxial walls extending aw ay from the disk 32 on the side opposite the tapered w all 314. These tubes 313, 332 partially overlap and collectively define distinct fluid path ways or lumens 31a (primarily associated with tube 313) and lumen 33a (primarily associated with tube 332). Thus, the wider tube 313 provides a shared outermost wall 313a that extends down to form the outer wall of tube 332. Tube 332 also includes a shared wall 313b close to the junction with the disk 32 in which lumen 31a is defined its inner facing and lumen 33a by its outer facing. In some aspects, the tube 332 has a C-shape radial cross section.

[0039] Tube 313, in conjunction with floor 321 and the aforementioned shared wall, fluidically connects to the aperture 323 and lumen 31a. Similarly, tube 332 directs fluid along lumen 33a and flow path RF (which includes the inner surfaces of tube 332, as well as the shared outermost wall 313a). This configuration allow-s the valve 2 to slide within a range of motion when actuation force is applied axially (either by compressing the system and / or by operation of gravity)- When actuation force is applied, the lumens 31 a and 33a are selectively sealed (i.e., opened or closed) so as to allow the flow of fluids along separate paths RA, RF through the system 1. Thus, as illustrated by Figs. 6A and 6B and, separately, 7A and 7B, the system 1 provides a unique means for refilling a vessel 6 that can be attached to the closure.

[0040] With this arrangement, return fluid from the vessel 6 may flow over the floor 321, through the aperture 321 formed where the disk 32 joins fluid delivery sections 31, 33, down the inner lumen of the tube 313. and into the refill container. Notably, valve 2 selectively controls flow along lumen 31a in concert with features on bottom end 21. while flow along lumen 33a is controlled by the wiper element 27.

[0041] Closure 4 includes a divided tubular element 40 having an H-like shape along its diameter, as seen in Fig. 10B. An threaded skirt 41 extending toward and engaging the vessel6, and a locking skirt 42 extending down and away from the threaded skirt 41. A radial protrusion 43 divides the skirts 41, 42, with coaxially offset extensions 411 and 421 also extending away from the surface of protrusion 43 on opposite facings. An annular sealing gasket 5 may rest in a corresponding groove formed on either or both sides of the protrusion 43.

[0042] Threads 412 are formed on a facing of the skirt 41 to allow" for connection to the refill vessel 6, although other common connection means can be employed. At the terminal, peripheral edge of the skirt 41, engagement formation 413 may be provided to serve as anti- back off ribs, ratchet teeth, or any other common and cooperating feature on / with the vessel 6.

[0043] The locking skirt 42 includes cooperating flange or tooth 422 on its outer facing, which is configured to engage and / or couple to the closure at catch projections 342. The thickness of the skirt 42 can increase at this point, so that the wall thickness increases as the skirt 42 approaches its junction with the protrusion 43. In the same manner, the thickness of the threaded skirt 41 is the same or greater than the locking skirt 42 to safeguard the structural support / integrity of the connections maintained by closure 4. However, the extensions 411 , 421 are comparatively thinner.

[0044] The locking skirt 42 also has a solid cylindrical extension with a series of locking edge formations 423 extending beyond it. Formations 423 include axial extensions 4231 that define the lower most peripheral edge of the piston 4. A series of circumferential extensions 4232 project orthogonally away from the axial extensions 4231 so as to define a guide slot 4234 useful for coupling the piston 3 to the closure 4. Specifically, interfacing ramps 344 and 4233 can capture and limit the rotational movement of the components.

[0045] Along the inner most axis of the closure 4, the offset extensions 411 and 421 are configured to coaxially receive portions of the piston 3. including the extension tube 311. Extension 421 will also interface with the positioning fins 322 as described above. Theextension 411 selectively seals with the wiper element 27 to open and close the flow paths shown in Figs. 6B and 7B.

[0046] The foregoing arrangement allows for an axial motion to open or close the valve 2 quickly, without the need to rotate components into position. This should allow for easier access and refilling operations, without the need for specialized necks or other features on the refill containers themselves.

[0047] In specific aspects, the invention comprises a refill system that attaches to a container at its neck. The container neck can be threaded and provides an opening to a volume that will receive refill fluid. The system includes a piston having a fluid delivery section extending axially away from a top facing of a disk member, wherein the fluid delivery skirt section includes a first lumen associated with a first tube and a second lumen associated with a second tube and wherein the first tube: i) has a shorter axial extension away from the disk member in comparison to the second tube, ii) carries through the disk member and extends axially away from a bottom facing of the radial protrusion, and iii) shares wall portions with the second tube in a region where the first and second tube connect to the disk member. The system also has a closure coupled to the piston along a periphery of the disk member and a valve comprising a hollow tube having a fluid port at a sealing end and a radial wiper extending away from the hollow tube. In operation, the sealing end of the valve is captured within a section of the first tube of the piston extending away from the bottom facing of the disk section so that, when the system is actuated, the sealing end selectively seal the first lumen and the radial wiper selectively seals the second lumen. Additional or alternative aspects include any one or combination of the following features:• wherein the closure includes an H-shaped body;• wherein the H-shaped body of the closure includes a threaded skirt and wherein the valve and the section of the first tube of the piston extending away from the bottom facing of the disk section are coaxially aligned within the threaded skirt;• wherein the threaded skirt includes engagement formations;• wherein the H-shaped body of the closure includes a locking skirt;• wherein the locking skirt includes a catchment on an outer facing that cooperates with a catchment formed on the periphery of the disk member;• wherein the locking skirt includes locking formations;• wherein the valve slides within a range defined by a catchment protrusion on inner surface of first tube and a stop mechanism created by engagement of the wiper and the section of the first tube of the piston extending away from the bottom facing of the disk section;• wherein the section of the first tube of the piston extending away from the bottom facing of the disk section includes a sealing bead engaging an outer surface of the hollow tube of the valve;• wherein the closure includes a radial protrusion that coaxially receives a portion of the piston;• wherein a tubular extension extends axially away from the radial protrusion and the portion of the piston is coaxially disposed therein;• where the tubular extension is configured to selective engage one or more fins extending from the bottom facing of the disk member;• wherein the disk member includes an axially extending skirt formed on the periphery;• wherein the an annular wall is coaxially disposed within and connected via one or more radial connectors to the axially extending skirt; and• wherein the radial connectors include formations that lock the closure to the piston.

[0048] In additional aspects, the invention contemplates a method for refilling a container. The method includes providing any of the aforementioned refilling systems. A gasket may be disposed on the closure and, more specifically, on the radial protrusion to create a seal with a container neck. The container neck is coupled to the system and force is applied to move the valve and allow for a first fluid to flow through the first lumen and a second fluid to flow through the second lumen. Thereafter, force is removed and the container (which is now filled) is decoupled from the system. Additional aspects include locking the piston to the closure when the closure is first attached to the container. Thus, the method does not require the entirety' of the aforementioned refilling systems to be assembled before initiating the method (i.e., theclosure may be coupled to the container neck and, thereafter, the piston and valve are snap- fitted and / or locked onto the closure / container combination).

[0049] All components of the pump dispenser should be made of materials having sufficient flexibility and structural integrity, as well as a chemically inert nature. Certain grades of polypropylene and polyethylene are particularly advantageous, especially in view of the absence of any thermosetting resins, elastomeric polymer blends, and other chemically distinct polymers or copolymers. Notably, high density polyethylene (i.e. , having a density of greater than 0.940 g / cm3) may be distinguished from lower density polyethylene types (e.g., medium density at 0.925 to 0.940 g / cm3and / or lower density at 0.880 to 0.925 g / cm3) for certain uses;, particularly when the resilience / rigidity of the material is at issue. More generally, the invention may be implemented relying on injection moldable polyolefins, with particular utility in polypropylene and polyethylene.

[0050] Significantly, the ability to construct a system and execute a method relying on components that are all constructed from plastics and, more preferably from a single grade of easily recycled plastic, should not be overlooked. Prior solutions often relied on metallic springs and / or difficult to recycle materials, such as elastomers, that are not compatible with recycling methods for other polymers, such as most injection-moldable polyolefins. When incompatible materials are used, it becomes necessary to disassemble and remove the non- compliant (e.g., metallic and / or elasotomeric) components. Thus, in one aspect of the invention all of the components of the refilling system are made from the same matenal and, more preferably from polypropylene and / or polyethyelene (or, at a minimum, polyolefins that do not contain any elastomers and / or that may all be recycled in a single stream).

[0051] References to coupling in this disclosure are to be understood as encompassing any of the conventional means used in this field. This may take the form of snap- or force fitting of components, although threaded connections, bead-and-groove, and bayonet-style / slot-and-flange assemblies could be employed. Adhesive and fasteners could also be used, although such components must be judiciously selected so as to retain the recyclable nature of the assembly.

[0052] In the same manner, engagement may involve coupling or an abutting relationship. These terms, as well as any implicit or explicit reference to coupling, will should be considered in the context in which it is used, and any perceived ambiguity7can potentially be resolved by referring to the drawings.

[0053] Although the present embodiments have been illustrated in the accompanying drawings and described in the foregoing detailed description, it is to be understood that the invention is not to be limited to just the embodiments disclosed, and numerous rearrangements, modifications and substitutions are also contemplated. The exemplary embodiment has been described with reference to the preferred embodiments, but further modifications and alterations encompass the preceding detailed description. These modifications and alterations also fall within the scope of the appended claims or the equivalents thereof.
