Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Application No. 17 / 496,162, entitled “Distributor,” filed October 7, 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a dispenser for distributing fluid, a cassette used with the dispenser and for containing the fluid to be dispensed, and a dispenser assembly including the dispenser and the cassette. Background Technology

[0004] Hand hygiene product dispensing systems typically consist of a product dispenser and a refillable and / or replaceable reservoir to hold the product to be dispensed.

[0005] Typically, there are two groups of people using this distribution system: maintenance professionals and users. These two groups have different requirements regarding what the distribution system must provide.

[0006] For maintenance professionals, visibility into the amount of product remaining in the dispenser's storage is essential to reduce the time spent assessing and repairing the dispenser. Insufficient product visibility may necessitate opening the dispenser to determine if the storage needs refilling or replacement, adding unnecessary time.

[0007] On the other hand, the visibility of the products in the dispenser should be minimized to enhance its hygienic and clean appearance and encourage its use. For example, users may be deterred by the unsightly internal workings of the dispenser or the appearance of a small amount of product.

[0008] The purpose of this disclosure is to resolve these two conflicting needs. Summary of the Invention

[0009] In one aspect, the dispenser includes a front panel with a visible light transmittance (VLT) value of zero and a body having walls having at least two VLT values. Two of the at least two VLT values ​​are greater than 5% and are different from each other.

[0010] In some embodiments, the ratio of the at least two VLT values ​​may be approximately 2:1, and the wall portion may have an observation portion with a VLT value greater than 5%. The wall portion is part of a sidewall having a surface area, wherein the surface area of ​​the observation portion is at least 30% of the total surface area of ​​the sidewall. Furthermore, at least 50% of the total surface area of ​​the sidewall includes VLT values ​​greater than 5% and less than the VLT value of the observation portion. In some aspects, the wall portion includes a first VLT value in at least two discrete and spaced-apart portions, the first VLT value being greater than a second VLT value.

[0011] In some implementations, the observation plane is defined at an edge formed between two VLT values, and the rear plane is defined by the rear wall of the body. Furthermore, an observation axis may extend through the front panel and perpendicular to the observation plane, a first observation boundary may extend from the observation plane at a first angle, and a second observation boundary may extend from the observation plane at a second angle.

[0012] In some embodiments, a first observation area is formed between a first observation boundary and a second observation boundary, wherein the front panel is disposed within the first observation area. Furthermore, a second observation area may be formed between the first observation boundary and the rear plane, with the two VLT values ​​of the sidewall disposed within the second observation area.

[0013] In some embodiments, the dispenser includes an opaque front panel and a body with a translucent wall, which includes a transparent window. The window may be positioned at an angle relative to the front panel.

[0014] In some aspects, the body includes a rear wall that may be substantially parallel to the front surface of the front panel, and the window may be disposed substantially perpendicular to the rear wall and the front panel between the rear wall and the front panel. Furthermore, the rear edge of the window may be spaced apart from the rear wall, and the front edge of the window may be spaced apart from the front panel. A wall portion may be part of a side wall and may extend from the rear wall of the body to its front edge. Additionally, the side wall may include a top and two opposing wall portions connected by the top. The front edge of the top of the side wall may extend further from the rear wall than the front edge of the wall portion. The window may be located on at least one of the wall portions.

[0015] In some aspects, the central plane bisects the front panel and rear wall of the dispenser, the window extends in a first direction substantially parallel to the central plane, and the window extends in a second direction angled relative to the central plane. Furthermore, the front edge of the window may be located at a first distance from the central plane, the rear edge of the window may be located at a second distance from the central plane, and the first distance may be greater than the second distance. The window may include a first window and a second window, and an inner cavity may be formed between the first window and the second window.

[0016] In some embodiments, the first window includes a first edge, and the second window includes a second edge, the first edge being disposed at an angle different from that of the front panel. The first window and the second window may each be located approximately centrally between the top and bottom of the wall portion.

[0017] In another aspect, the dispenser includes a front panel that may be opaque, and a body including sidewalls extending from a rear wall. Furthermore, the front panel is coupled to the body, forming an internal cavity therebetween. The sidewalls include an illumination portion and an observation portion. The illumination portion is translucent, and the observation portion is transparent. Additionally, the observation portion is located between the front panel and the rear wall, and both the observation portion and the illumination portion can be configured to indicate the refill status.

[0018] In some aspects, the refill status of the dispenser may include at least two indicators, a first indicator configured to be positioned along a first direction and a second indicator configured to be positioned along a second direction, the first and second directions being different from each other. Furthermore, the viewing portion may be defined by a front edge and a rear edge extending between a top edge and a bottom edge. In some embodiments, the rear edge is positioned near the rear wall, and the front edge may be positioned near the front panel.

[0019] In some embodiments, the box is adapted to be received within an inner cavity and includes a side extending between a front and a rear side, a base, and a neck disposed opposite the base. The base may be configured to engage with the top edge of an observation portion to provide a first indicator of refill status. In some examples, the box is configured to collapse during use, and the front and rear sides are configured to move toward each other as the box collapses. The base may be configured to move toward the neck as the box collapses, and the box is configured to collapse from a first state to a second state and then to a third state. Each of the front side, the rear side, and the base may be configured to be hidden and invisible through the observation portion in the first state. Furthermore, at least one, but no more than two, of the front side, the rear side, and the base may be configured to be visible through the observation portion in the second state. Additionally, each of the front side, the rear side, and the base may be configured to be visible through the observation portion in the third state.

[0020] In some aspects, at least one of the observation portion and the lighting portion may include a symbol that can be configured to convey information about at least one aspect of the refill state. The refill state may be configured to be conveyed through color contrast. The observation portion may include multiple transparent areas, each of which is defined by the lighting portion on all sides. Furthermore, the lighting portion may include an opening, and the observation portion may not include an opening.

[0021] In another aspect, the cartridge within the dispenser includes an outlet end, a base end opposite the outlet end, a front wall, a rear wall, and two side walls. The outlet end has a shoulder and an annular collar extending about an axially extending neck that defines an opening into the internal volume of the cartridge. The front wall, rear wall, and two side walls extend from the outlet end to the base end. A vertical plane is centrally located between the two side walls and intersects the front and rear walls. Furthermore, the two side walls include a first side wall and a second side wall, each carrying a corresponding first and second valley. Each of the first and second valleys is defined by a top peripheral edge, a front peripheral edge, a rear peripheral edge, and a bottom peripheral edge. A front panel extends from the front peripheral edge toward a vertical fold line, a rear panel extends from the rear peripheral edge to the vertical fold line, a top panel extends from the top peripheral edge to the vertical fold line, and a bottom panel extends from the bottom peripheral edge to the vertical fold line. The vertical fold line is positioned closer to the vertical plane than the top peripheral edge, front peripheral edge, rear peripheral edge, and bottom peripheral edge. Vertical fold lines extend between the upper joint connecting to the upper paired angled fold lines and the lower joint connecting to the lower paired angled fold lines. The upper panel extends between the upper paired angled fold lines, and the lower panel extends between the lower paired angled fold lines, with the surface area defined by the upper panel being smaller than the surface area of ​​the lower panel. The upper joint is positioned closer to the top outer edge than the lower joint, which is positioned closer to the bottom outer edge.

[0022] In some embodiments, each of the upper and lower panels may be substantially triangular and have a substantially flat surface. Furthermore, when the container collapses under a vacuum applied to extract fluid from the opening, the front and rear walls are pulled toward each other, and the first and second sidewalls may fold along corresponding upper and lower pairs of fold lines and vertical fold lines.

[0023] On the other hand, the box includes a front wall, a rear wall, a pair of side walls, and a base opposite the neck. The box also includes a shoulder section extending at an angle from the neck to each of the front wall, rear wall, and pair of side walls; an opening extending through the neck to the internal volume; a vertical axis extending centrally through the box; and multiple creases. A first crease and a second crease each extend perpendicular to the vertical axis along the front wall and between the pair of side walls. The first crease may be located at a first distance from the shoulder, and the second crease may be located at a second distance from the base. The second distance may be greater than the first distance.

[0024] In some embodiments, the box may be at least partially opaque. In other embodiments, the box may be at least partially translucent, having a VLT value greater than 5%. In some examples, a label may be attached to at least one of the front and rear walls. In some embodiments, a rib may extend along the shoulder between the neck and one of a pair of side walls. In some examples, a first crease and a second crease may define a collapse pattern, and the box may be configured to collapse according to the collapse pattern.

[0025] In another aspect, the box includes an internal volume, a neck extending from a shoulder portion, a front wall opposite a rear wall and a right wall opposite a left wall, and a base. The neck defines an opening communicating with the internal volume cavity. The box is configured to be inserted into a dispenser having an opaque front panel and a body comprising at least two visible light transmittance (VLT) values, each of which is greater than 5%.

[0026] In some embodiments, the box has a VLT value greater than 5%. In some aspects, when the box is inserted into the dispenser, a first portion of the box is configured to be visible through an observation portion with a VLT value greater than 5%, and a second portion of the box is configured to be hidden and invisible through the observation portion. In some aspects, a label is affixed to at least one of the front and rear walls, and the label can be configured to be hidden and invisible when the box is inserted into the dispenser. The box can be configured to be received by the dispenser in an inverted orientation. In some instances, the box is configured to contain fluid within the internal volumetric cavity, and the fluid is configured to be visible when the box is inserted into the dispenser.

[0027] On the other hand, a dispenser for dispensing fluid is provided, the dispenser including a dispenser body that at least partially defines the interior of the dispenser and is configured to receive a cartridge containing fluid to be dispensed. In some embodiments, the dispenser body includes a front panel configured to be presented to a user during use. In some embodiments, the front panel includes an opaque material such that at least a portion of the interior of the dispenser is not visible through the front panel. In some embodiments, the dispenser body includes an illumination portion configured to allow ambient visible light to enter the interior of the dispenser through the illumination portion. Furthermore, the body includes an observation portion configured to face a different direction from the front panel during use, and the observation portion is configured to allow observation of the cartridge through the observation portion. In this way, the dispenser simultaneously meets the observation requirements of maintenance professionals and users or owners.

[0028] When using a dispenser, users typically stand close to and in front of the front panel to operate it and dispense fluid. The front panel conceals at least part of the internal dispenser for improved aesthetics, which is particularly desirable in high-end, high-flow commercial environments, such as public restrooms.

[0029] In addition, maintenance professionals want to be able to quickly assess the fluid volume in the dispenser to determine when it will require maintenance, such as cartridge replacement. This assessment typically takes place at a distance from the dispenser, and preferably without opening or obstructing access to the dispenser.

[0030] Therefore, the lighting and viewing sections provide an efficient way to assess the amount of fluid remaining in the dispenser, while also offering improved aesthetics for the user. Maintenance professionals can assess the amount of fluid remaining in the dispenser through the viewing section, which faces a different direction than the front panel. The interior of the dispenser is illuminated by ambient visible light entering through the lighting and viewing sections. In some embodiments, the fluid filling lines are visible through the viewing section and housing to facilitate assessment of the fluid volume in the dispenser by maintenance professionals. This is particularly important when the fluid itself is difficult to see (e.g., transparent, translucent, or light-transmitting). In this way, maintenance professionals can effectively determine the amount of fluid in the dispenser from a distance without opening or obstructing access to the dispenser. Furthermore, improved visibility of the fluid volume in the dispenser can improve refilling or maintenance efficiency by saving maintenance professionals time and by enabling more accurate determination of the dispenser's level or condition.

[0031] In some embodiments, the lighting section is configured to be vertically upward during use, for example, located at the top. In this way, the interior of the dispenser is illuminated by ambient visible light provided by overhead lighting, a skylight, etc. Furthermore, the front panel may define a first observation area, and the observation section may define a second observation area. In the first observation area (e.g., the actuation observation area), the housing inside the dispenser is hidden or concealed by the front panel. In the second observation area, the housing housed inside the dispenser is visible through the observation section. In some embodiments, the second observation area comprises a pair of observation areas located on opposite sides of the first observation area. In this way, a maintenance professional can assess the fluid volume within the dispenser without being directly in front of the dispenser, for example, in the first or actuation observation area.

[0032] It is conceivable that the front panel is entirely made of opaque material. It is also conceivable that the lighting and / or viewing portions are made of transparent, translucent, and / or light-transmitting materials. In this way, effective illumination is achieved within the dispenser while concealing or obscuring the interior of the dispenser from a specific viewing angle or field of view, for example, within a first viewing area or actuated viewing area. It is also conceivable that the lighting portions are provided as translucent, for example, by treating the inner surface of the material forming at least a portion of the lighting portions. In some embodiments, such treatment may include etching according to various methods. In some embodiments, such treatment may include abrasive or applying a substance, substrate, adhesive, etc.

[0033] In some embodiments, the viewing portion is provided to be transparent or semi-transparent. In some embodiments, the viewing portion is centrally located between the front and rear portions of the dispenser. In some embodiments, the viewing portion is positioned closer to the rear portion of the dispenser than the front portion. In some embodiments, when in a closed configuration, the dispenser has a body depth from the foremost edge to the rearmost edge, and the viewing portion has a viewing depth from the front edge to the rear edge. Furthermore, the center point of the viewing depth of the viewing portion is located behind the center point of the body depth of the dispenser.

[0034] In some embodiments, the observation section includes multiple regions through which the interior of the dispenser is visible, such as multiple transparent regions. Furthermore, the multiple regions may be spaced apart from each other and positioned to align with the cartridge. In this way, the observation section can be configured to expose multiple portions of the cartridge to effectively represent all liquid levels from full to empty through a single observation section. In some embodiments, the observation section includes multiple discrete regions, such as small regions, configured to enhance aesthetics. In some embodiments, the discrete regions are configured to align with specific portions of the cartridge associated with a specific liquid level from full to empty, such that a single discrete region exposes a binary indication of the liquid level. In some embodiments, the observation section includes multiple observation sections located on opposite sides of the dispenser. In this way, visibility of the interior of the dispenser can be achieved through any of the multiple regions or discrete regions.

[0035] In some embodiments, the front panel of the dispenser includes a curved profile in the left-right direction, such that the front panel curves outward relative to the rear wall of the dispenser. In some aspects, the body of the dispenser includes a rear wall, from which a top and an opposite side extend. In some embodiments, the top of the body extends further from the rear wall than the opposite side. Additionally, the front panel is fitted onto the top and opposite sides of the body such that the top and opposite sides are configured to mate with the curved profile of the front panel. In this way, when the lighting portion is formed on the top of the dispenser, a greater amount of ambient visible light can enter the interior of the dispenser. Therefore, the internal housing of the dispenser is not visible through the front panel, and the curved profile of the front panel enhances the aesthetics of the dispenser. The curved profile of the front panel also corresponds to the opposite side relative to the overall depth of the dispenser, on which the viewing portion is positioned closer to the rear of the dispenser, making the viewing portion more discrete.

[0036] In some embodiments, the dispenser body includes sidewalls extending from the rear wall, and the sidewalls extend around a first side, a top, and a second side of the dispenser to form a continuous sidewall. In some embodiments, the dispenser may include a curved upper surface extending between the first and second sides of the dispenser. In other embodiments, the sidewalls may include a first sidewall, a top wall, and a second sidewall, which may be integrally formed as a single component or made of separate components. In some embodiments, the first sidewall, the second sidewall, and the top wall are substantially straight and joined together at an angle (e.g., 90 degrees).

[0037] In some respects, the sidewalls extend inwards as they extend toward the rear wall. In other words, the front of the dispenser has a larger area in the front view compared to the rear. In other words, the sidewalls taper inwards as they extend from the front panel toward the rear wall. This allows for more discrete positioning of the viewing and / or lighting portions, thereby enhancing the dispenser's aesthetics and the user's viewing experience.

[0038] In some embodiments, the observation and / or lighting portions are provided by the sidewalls of the dispenser body. In some embodiments, the observation and / or lighting portions are integral with the sidewalls of the dispenser body. In this way, the number of parts required to manufacture the dispenser is reduced, thereby reducing the dispenser manufacturing cost and material consumption.

[0039] In some embodiments, the lighting portion is formed of a translucent material, and the viewing portion is formed of a transparent material. In some embodiments, the lighting portion is provided through an area of ​​the sidewall formed of a translucent material.

[0040] In some embodiments, the dispenser includes a support structure, such as a collar, for supporting a cartridge housed within the dispenser, and the sidewalls include a translucent material in the region of the support structure to at least partially prevent observation of the support structure through it. Additionally, the front panel includes a light-shielding element extending across a region corresponding to the area where the support structure is located to at least partially prevent observation of the support structure. Since the support structure can be considered unsightly, providing a translucent material in the region of the support structure and / or the light-shielding element of the front panel improves the aesthetics of the dispenser and the user's viewing experience.

[0041] In some embodiments, the dispenser body has a first body portion and a second body portion, the first body portion including, for example, a front panel and a portion of a sidewall, and the second body portion including, for example, a rear wall and a portion of a sidewall. In some embodiments, the first body portion and the second body portion are movable relative to each other between a closed configuration and an open configuration, in which the interior of the dispenser is covered and in which the interior is exposed. In some embodiments, the first body portion and the second body portion are configured to pivot relative to each other about a hinge axis located at the lower end of the dispenser.

[0042] In some embodiments, the hinge axis is substantially horizontal when the dispenser is in use. This provides an opening mechanism that allows maintenance personnel easy access to replenish fluid in the dispenser. It should be understood that any suitable mechanism for accessing the interior of the dispenser can be used. In some aspects, the dispenser is configured to be fixed to a substantially vertical surface via a rear wall. In some aspects, the rear wall and side walls are integrally formed. In this way, setting the rear wall and side walls as a single integrally formed component reduces the number of parts in the dispenser and thus reduces cost and material consumption. In some embodiments, the side walls are configured to extend from the rear wall such that they intersect with the front panel when the dispenser is in a closed configuration.

[0043] On the other hand, a dispenser assembly is provided, comprising a dispenser as disclosed herein and a cartridge housed within the dispenser and containing fluid to be dispensed. The cartridge is configured to collapse in a predetermined manner upon dispensing the fluid. Thus, the dispenser disclosed herein, when used with the collapsible cartridge, effectively conceals the cartridge so that the dispenser is not visible to a person using the dispenser (i.e., a person in a first observation area), thereby providing improved aesthetics while also enabling maintenance professionals to assess the amount of fluid in the cartridge.

[0044] In some cases, maintenance professionals will assess the fluid volume in the cartridge based on a combination of the remaining fluid level and / or the degree of collapse. Therefore, the visibility of the cartridge via the observation section and the illumination via the lighting section ensure that maintenance professionals can easily perform this assessment. Collapsible cartridges (i.e., sealed cartridges) are also advantageous in overcoming the hygiene problems associated with non-sealed systems. Fluid quality can be maintained by using sealed cartridges that cannot be refilled with product and prevent air from entering the cartridge during fluid dispensing.

[0045] In some embodiments, the observation section of the dispenser is configured, for example, to be sized, shaped, and positioned such that the fluid fill level of the cartridge can be observed through the observation section when the fluid fill level is between an upper and lower level. In some aspects, a higher level corresponds to the cartridge being 20% ​​or more full, such as 40%, 50%, 60%, 80%, or 100%. In some embodiments, a lower level corresponds to the reservoir being less than 20% full or substantially empty. In this way, the observation section only needs to be large enough to see a portion of the collapsed cartridge to determine the amount of fluid remaining in the cartridge. This ensures that the observation section can be minimized, i.e., smaller in size, to enhance the dispenser's aesthetics without hindering the ability of maintenance professionals to assess the amount of fluid in the cartridge.

[0046] In some embodiments, the viewing portion is narrower than the widest part of the box when viewed in its side profile. In some aspects, the viewing portion is narrower than the widest part of the box when viewed in its side profile when the box collapses from 100% full to empty. In this way, the size of the viewing portion can be reduced to improve the aesthetic appearance of the dispenser without impairing the ability of maintenance professionals to assess the amount of fluid in the box.

[0047] In some embodiments, the cartridge includes fold lines arranged such that the predetermined collapse pattern involves the cartridge collapsing so that, when viewed in the side profile, a narrow waist is formed between the relatively wide upper and lower portions of the cartridge when the cartridge is depleted. This waist includes portions of the foremost and rearmost walls. In other words, the side profile of the cartridge resembles a shape similar to the cross-section of an I-beam. In this way, most of the deformation occurring within the cartridge occurs in the side profile and follows a unique collapse pattern. This aids maintenance professionals in determining the amount of fluid remaining in the cartridge by considering the visible fluid fill level in conjunction with the cartridge's collapse shape. Based on this and the maintenance professional's experience with dispenser usage, the professional can assess whether replenishment and / or refilling and / or cartridge replacement is necessary.

[0048] In some embodiments, the observation portion of the dispenser is configured (e.g., sized and / or positioned) such that the foremost and / or rearmost walls of the waist section can be observed when the box is 80% or less full, e.g., 60% or less full, e.g., 40% or less full, e.g., 20% or less full. In this way, the observation portion is constructed to observe the waist section of the box as it collapses. This is important because once the box collapses in this manner, the visible fluid fill level within the box becomes more significant in determining the amount of fluid remaining in the box. At such a collapse level, the amount of fluid remaining in the box will be relatively low, therefore an accurate assessment of the visible fluid level is important in the evaluation by maintenance professionals. This also ensures that the observation portion is minimized, i.e., as small as possible, to improve accommodation to the user's expectation of concealing the box. In some embodiments, when the box is approximately 100% full, the height of the observation portion is less than the height of the box. In this way, a more discrete observation portion is provided.

[0049] In some implementations, the front panel extends to cover an area corresponding to the interior region of the receiving box, thereby obstructing or preventing observation of the box through the front panel. In this way, the dispenser has an enhanced aesthetic, where the box is hidden and not visible.

[0050] In some embodiments, the dispenser includes a guide structure, and the cassette includes a corresponding positioning structure that corresponds to the guide structure to facilitate mounting the cassette in the dispenser. In this way, proper positioning of the cassette within the dispenser is ensured, which is important for ensuring correct alignment of the viewing portion with the cassette when it collapses.

[0051] In some embodiments, the box includes an opening defined by a neck that is connected to the box body via a shoulder, and the shoulder is provided with ribs to reinforce the shoulder during box collapse to prevent deformation. The collapse of the box can be controlled such that a waist position is provided towards the base of the box, i.e., opposite the neck / opening. This facilitates fluid distribution from the box, making it less likely for fluid to become trapped within the box.

[0052] In some implementations, the box is placed in the dispenser with the opening positioned at the bottom, i.e., inverted. Therefore, the arrangement of the ribs has been found to have the effect of moving the constricted waist position away from the neck of the box, i.e., upwards towards the base of the box. This reduces the chance of fluid becoming trapped in the area above the waist of the box (i.e., between the waist and the base of the box).

[0053] On the other hand, when the box deforms, the ribs effectively maintain the shape of the shoulder. For example, the ribs at least partially prevent the shoulder from deforming to form a hole in which fluid could become trapped when the box is in use. In some aspects, the ribs extend radially outward from the neck and in opposite directions relative to each other, for example, arranged 180 degrees to each other relative to the central axis of the neck. In some embodiments, the ribs extend from the neck toward the box body. In some aspects, the ribs include a pair of support ribs that extend in substantially opposite directions relative to each other and relative to the neck. In some aspects, the ribs extend laterally from the neck.

[0054] In some embodiments, one or more support ribs may extend in the left-right direction. It should be understood that, when viewed from the side during collapse, the side of the box corresponds to the side in which the narrow waist is formed. In some embodiments, the box body includes a front wall and a rear wall, a first side wall and a second side wall, wherein the first and second side walls extend between the front and rear walls. In some embodiments, the front wall, rear wall, first side wall and second side wall extend between the base and shoulder of the box, such that the first and second side walls are viewed when the box is viewed in their respective side profiles. In some embodiments, the front wall and / or rear wall include curved profiles in the left-right direction, such that they curve outwards relative to the interior of the box. This allows for the provision of increased box volume while still achieving the desired predetermined collapse profile.

[0055] In some embodiments, the front and / or rear walls include one or more fold lines extending in the lateral direction. This facilitates folding the box into a generally "I-beam" shape when it collapses. In other words, the side profile of the box when collapsed takes on a shape similar to the cross-section of an I-beam. In some embodiments, the front and / or rear walls include a pair of transverse fold lines distributed along the height of the box body, wherein the first and / or second fold lines are offset from a uniform interval along the height of the box body in a direction toward the neck. For this purpose, when a pair of fold lines are provided in the front and / or rear walls, if these fold lines are uniformly distributed along the height of the box body, they will be positioned at one-third and two-thirds of the height, respectively. When the fold lines are offset from this uniform interval, they are offset from one-third and two-thirds positions, respectively, in a direction toward the neck of the box. It has been found that positioning the fold lines in this way ensures a more desirable collapsed profile, where the waist portion moves away from the neck of the box.

[0056] In some embodiments, the first sidewall and / or the second sidewall includes one or more of the fold lines extending in a longitudinal direction (i.e., in the direction extending between the base and the neck of the box). This can be considered a longitudinal fold line. This is advantageous for folding the box into a generally "I-beam" shape when the box collapses. In other words, the side profile of the box when collapsed adopts a shape similar to the cross-section of an I-beam. In some embodiments, the longitudinal fold line of the first sidewall and / or the second sidewall includes a first end near the neck of the box and a second end near the base of the box. The distance between the first end and the upper end of the box near the neck is less than the distance between the second end and the lower end of the box near the base. In other words, in the presence of longitudinal fold lines having a first end and a second end disposed in the first sidewall and / or the second sidewall, if the first end and the second end are to be evenly distributed along the height of the box, they will be positioned at one-third and two-thirds of the height of the box, respectively. In the case where the first end and the second end of the respective longitudinal fold line are offset from this uniform interval, they are offset from the one-third and two-thirds positions, respectively, in the direction toward the neck of the box. It has been found that positioning the longitudinal fold lines in this manner ensures a more desirable collapsed profile, with the waist portion moving away from the neck of the box.

[0057] In some embodiments, the upper front fold line and / or the upper rear fold line extend from a first end of the longitudinal fold line. The upper front fold line extends from the first end toward the front wall, for example, toward a corner formed between the front wall and the shoulder. The upper rear fold line extends from the first end toward the rear wall, for example, toward a corner formed between the rear wall and the shoulder. In some embodiments, the lower front fold line and the lower rear fold line extend from a second end of the longitudinal fold line. The lower front fold line extends from the second end toward the front wall, for example, toward a corner formed between the front wall and the base. The lower rear fold line extends from the second end toward the rear wall, for example, toward a corner formed between the rear wall and the base. In some embodiments, the first end of the longitudinal fold line is positioned longitudinally aligned with a transverse fold line on the front wall and / or the rear wall. In some embodiments, the second end of the longitudinal fold line is positioned longitudinally aligned with a transverse fold line on the front wall and / or the rear wall.

[0058] In some embodiments, the box body defines a valley in which a corresponding fold line is located. In this way, the box is induced to collapse in a predetermined manner. Therefore, enhanced control over the collapse of the box is provided because the valley ensures a slight folding of the fold line in the collapse direction. In some embodiments, the depth of the box between the front and rear walls narrows at the location of the fold line. In some embodiments, the box is blow-molded. This provides an easy manufacturing method.

[0059] In some embodiments, the support ribs are hollow, allowing them to extend into the interior of the box.

[0077] This disclosure relates to a dispenser assembly for distributing fluid. The dispenser assembly includes a dispenser and a fluid cartridge. While embodiments of this disclosure may take many different forms, several embodiments are discussed herein, and it should be understood that this disclosure is to be considered exemplary and is not intended to limit the invention to the embodiments shown.

[0078] Furthermore, the fluids discussed herein may include soap, shampoo, hand sanitizer, detergent, cleaning agent, or other desired fluids. As used herein, the term "soap" is intended to include any liquid detergent or cleaning product suitable for dispensing from a fluid dispenser. Additives may be included in the fluid and / or soap, such as fragrances, preservatives, humectants, dyes, and particles.

[0079] As used herein, the term "transparent material" is intended to refer to any material that allows light to pass through so that objects behind it can be clearly seen. As used herein, the term "translucent material" is intended to refer to any material that allows some light to pass through but objects behind it cannot be clearly seen.

[0080] Furthermore, "visible light transmittance" is used herein as a measure of the amount or quantity of visible light that is allowed to pass through a material, and it can be expressed as a percentage. For example, a layer or surface that transmits half of the visible light is considered to have a 50% VLT value. "Transparent materials" are associated with high VLT values, ranging from 86% to 100% VLT. "Translucent materials" are associated with low or medium VLT values, ranging from 6% to 85% VLT. "Opaque materials" are associated with no VLT value or a very low VLT value (5% or less VLT).

[0081] For clarity, those skilled in the art will understand that numerous standards exist for measuring the transparency / transparency / opacity of materials. In this embodiment, ASTM Standard D1003 2021 (Standard Test Method for Haze and Light Transmittance of Transparent Plastics) is used to measure visible light transmittance and thus the relative transparency / transparency / opacity of the material described herein. Furthermore, the recommended test protocol is intended to be followed for the specific material under review, and if Procedure A using a haze meter or Procedure B using a spectrophotometer provides different visible light transmittance results / percentages, the higher value of the two procedures is used for the purposes of this disclosure. It is also contemplated that if the subject material considered for the purposes of this disclosure has a non-planar construction, such as a curved window in the subject device, the planar portion of the particular material is used for testing purposes.

[0082] Alternatively, ASTM Standard D1746-2021 (Standard Test Method for Transparency of Plastic Sheets) can be used to measure the opacity of the materials described herein using suitable standardized equipment such as an opacity meter, and thus to measure relative transparency / transparency / opacity. As used herein, the term "opacity" refers to the degree to which a surface, object, or layer of material impedes the transmission of light through it, and is therefore the reciprocal of the VLT measurement mentioned herein. Opacity and VLT are intended to be used interchangeably, and measurements according to ASTM D1003 or ASTM D1746 can be used; however, for the purposes of this disclosure, measuring VLT according to the ASTM D1003 scheme is preferred. Furthermore, in cases where alternative materials are used, other standards should be followed, such as ASTM C1549-14-2021 (Standard Practice for Instrumented Transmittance Measurement of Color in Coated and Uncoated Flat Glass), etc.

[0083] Refer to the attached diagram. Figure 1-4A dispenser assembly 100 is depicted having a dispenser 110 adapted to receive a refill or cartridge 120. Dispenser 110 includes a front panel or cover 130 movably coupled to a body 140 to close an interior cavity 142. In one example, the front panel 130 is rotatable or pivotable about a hinge 144, but other configurations are possible. The body 140 includes a wall or sidewall 146 extending from a rear wall or backplate 148 to at least partially define the interior cavity 142. The rear wall 148 is configured to mount to an outer surface (not shown), such as a wall, a freestanding support, or any other suitable surface. A cartridge 120 is configured to be received within the interior cavity 142, and specifically, the cartridge 120 is mounted in an inverted orientation within a collar 150 carried by the body 140. The cartridge 120 includes a pump assembly 152 and a nozzle 154 configured to apply suction or vacuum to dispense fluid when the pump assembly 152 is actuated by a user.

[0084] In the illustrated embodiment, the rear wall 148 is a substantially planar portion, and the side wall 146 extends from the periphery 156 of the rear wall 148 to at least partially define the cavity 142. The side wall 146 extends from the rear end 158 to the front end 160 and from the top end 162 to the bottom end 164. In the illustrated embodiment, the recessed segment 166 extends along the rear end 158 of the side wall 146 and the rear wall 148, and preferably extends from the top end 162 to the bottom end 164. Furthermore, the recessed segment 166 curves inward from the top end 162 of the side wall 146 to the rear wall 148, but other configurations are also possible. Additionally, the dimensions of the recessed segment 166 may vary along the body 140, for example, being larger near the top end 162 of the side wall 146 and smaller toward the bottom end 164, but other configurations are also possible. Furthermore, sidewall 146 includes opposing sides 168, 170 (i.e., the first side and the second side) extending from the top end 162 to the bottom end 164 and from the rear end 158 to the front end 160. Figure 1-4 In the illustrated embodiment, the top end 162 connects to each of the opposing sides 168, 170 at the transition portion 172. Furthermore, as... Figure 1 , Figure 2 and Figure 4 As shown, the top end 162 includes an opening 174 formed therethrough, in which an opaque release device 175 is disposed.

[0085] In the illustrated embodiment, the body 140 and the front panel 130 are made of plastic material. A preferred plastic material is ABS resin (acrylonitrile-butadiene-styrene). However, other plastic materials may be used without departing from the scope of this disclosure, such as PC resin (polycarbonate polymer), PETG resin (polyethylene terephthalate), PP resin (polypropylene polymer), poly(methyl methacrylate) (PMMA or acrylic), styrene-methyl methacrylate (SMMA), polystyrene (PS), styrene-methyl methacrylate copolymer (MS), cured polyurethane, polyester, silicone resin, PVC resin (polyvinyl chloride), etc. Preferably, the body 140 is made of the same transparent resin as the plastic material used to construct the front panel 130. However, in some embodiments, the front panel 130 is made of a different plastic material than the body 140. It is also conceivable that the body 140 may be made of portions of different materials. In some examples, portions of the body 140 are made of glass, such as water-clear (low-iron) glass. Alternatively, sidewall 146 or portions thereof may be made of ABS resin, while other portions of the sidewall and / or body 140 may be made of another of the aforementioned plastics. Furthermore, it is conceivable that the VLT value of any material and / or portion of the dispenser may be a function of the material used and any surface treatments or coatings applied thereto. In some instances, surface treatments (e.g., molding, stamping, printing, compression, cutting, etching, sanding, vacuum forming, etc.) and / or coatings (e.g., paint, adhesives, etc.) may be applied to one or opposite sides of the plastic material to control its VLT value.

[0086] like Figure 1As shown, the front panel 130 is coupled to the front end 160 of the side wall 146 of the body 140 and spans between the top end 162 and the bottom end 164, as well as the opposite sides 168 and 170. The front panel 130 includes a front wall 180, which is coupled to a periphery 184 and extends from an upper portion 188 to a lower portion 192 and between the sides 194 and 196. A trigger or actuator 198 is coupled to the front panel 130 at the lower portion 192 to be substantially flush with the front wall 180, and the trigger 198 has a curved periphery 198a extending around it. The midpoint 200 of the front panel 130 is centrally located on the front wall 180, between the periphery 184 and between the upper segment 188 and the lower segment 192 of the front wall 180. Furthermore, the periphery 184 includes a peak 202 located at the highest point of the front panel 130, and the peak 202 intersects the central plane 204, which also intersects the midpoint 200. Additionally, the lowest point 203 of the distributor 110 is positioned along the curved bottom edge 198a of the trigger 198. The central plane 204 is further defined by a central axis 206, which passes through the distributor 110 and is centrally located between opposite sides 168 and 170 and between the rear wall 148 and the front wall 180, such that the central plane 204 also intersects the central axis 206. Thus, the peak 202 of the periphery 184, the lowest point 203 of the front wall 180, and the midpoint 200 are coplanar with respect to the central plane 204.

[0087] refer to Figures 2 to 4 The central axis 206 is shown extending generally vertically in a top-to-bottom direction. Furthermore, the transverse axis 210 is shown centrally positioned between the top end 162 and the bottom end 164 of the body 140. The transverse axis 210 extends generally horizontally in a front-to-back direction substantially perpendicular to the central axis 206. The central plane 204 extends through the central axis 206 and bisects the distributor 110, including the front panel 130 and the rear wall 148. Figure 3As shown, the depth D1 of the dispenser 110 is measured in a direction parallel to the transverse axis 210. Specifically, the depth D1 is measured between the front plane 215 and the rear plane or back plane 214. The front plane 215 is parallel to the central axis 206 and tangent to or otherwise coincides with the foremost portion of the front wall 180. The rear plane 214 is parallel to the central axis and tangent to or otherwise coincides with the rearmost portion of the rear wall 148 of the body 140. Furthermore, the depth D2 of the body 140 is measured between the front end plane 216 and the rear plane 214 of the body 140. The front end plane 216 is parallel to the central axis 206 and tangent to or otherwise coincides with the portion of the front end 160 aligned with the transverse axis 210. When the front panel 130 is attached to the body 140, the depth D2 is measured between the front end plane 216 and the rear plane 214. Additionally, the height H1 of the dispenser 110 is measured in a vertical direction parallel to the central axis 206. Specifically, the height H1 is measured with reference to the bottom plane 217 and the top plane 218, the bottom plane 217 being parallel to the transverse axis 210 and tangent to or otherwise coincident with the lowermost portion of the distributor 110, and the top plane 218 being parallel to the transverse axis 210 and tangent to or otherwise coincident with the uppermost portion of the distributor 110. When the front panel 130 is attached to the body 140, the top plane 218 is aligned with the peak 202, and the bottom plane 217 is aligned with the lowest point 203. It should be understood that although the lowest point 203 is located on the trigger 198, the distributor 110 can accommodate various triggers of any size and / or shape, such that the lowest point 203 can be located on the body 140 instead of the trigger 198.

[0088] In some embodiments, sidewall 146 and rearwall 148 are integrally formed with each other. Furthermore, sidewall 146 extends in a continuous U-shape from bottom end 164 to top end 162 and extends substantially linearly between front end 160 and rear end 158. Additionally, opposing sides 168, 170 extend substantially linearly between top end 162 and bottom end 164, and transition portion 172 curves downward from top end 162 to each of opposing sides 168, 170. It should be understood that opposing sides 168, 170 may be referred to as first side 168 and second side 170, or left and right sides, respectively. The front end 160 of sidewall 146 generally curves between top end 162 and bottom end 164 of sidewall 146 such that top end 162 extends further from rear wall 148 than opposing sides 168, 170. Therefore, front end 160 is furthest from rear wall 148 and / or rear end 158 at top end 162. Therefore, the depth D2 of the main body 140 at the top 162 is greater than the depth along the opposite sides 168, 170. More specifically, the uppermost and foremost portions of the main body 140 are aligned with the upper end plane 218 and the front plane 215 so as to have a depth greater than D2 from the rear plane 214 and a height approximately equal to the height H1 from the bottom plane 218, while the opposite sides 168, 170 are aligned with the front end plane 216 so as to have a depth approximately equal to D2 from the rear plane 214.

[0089] refer to Figure 3 and Figure 4 The sidewall 146 includes windows 220, 224 along it, and specifically, each of the opposing sides 168, 170 includes windows 220, 224 respectively, located between the top end 162 and the bottom end 164 of the sidewall 146, and respectively located substantially centrally between the transition portion 172 and the bottom end 164 on the opposing sides 168, 170. In some embodiments, the windows 220, 224 are located between and spaced apart from the top end 162 and the bottom end 164 of the body 140. Preferably, the windows 220, 224 are integrally formed with the sidewall 146 of the body 140 so as to be made of the same plastic material as the body 140, such as those described above. In some embodiments, the windows 220, 224 are separable components from the body 140 and may be made of a different material than the body 140, such as one of the plastic materials or glass materials described above.

[0090] Each window 220, 224 extends from the top edge 226 to the bottom edge 228 in a generally vertical direction parallel to the central axis 206, and from the front edge 230 to the rear edge 232 in a generally horizontal direction parallel to the horizontal axis 210. For example... Figure 3As shown, the top edge 226 of window 220 is positioned near transition portion 172 and is set at an angle (e.g., about 5 degrees) relative to the lateral axis 210 as it extends between the front edge 230 and the rear edge 232. It should be understood that the front edge 230 and top edge 226 of window 220 intersect at a point H2 away from the bottom plane 217. Furthermore, the viewing plane 236 is coplanar with the front plane 216 and aligned with a portion of the front edge 230 of each window 220, 224, such that each window 220, 224 extends substantially behind the viewing plane 236.

[0091] Furthermore, the bottom edge 228 extends from the rear edge 232 to the front edge 230 at an angle (e.g., about 5 degrees) and intersects the front edge 230 at a distance H3 from the bottom plane 217. The front edge 230 and the rear edge 232 are substantially parallel to each other and extend generally vertically, both substantially parallel to the central axis 206. The front edge 230 extends along the front end 160 of the sidewall 146 and follows the shape of the perimeter 184 of the front panel 130, and is located at least partially at a depth D2 from the rear plane 214. In some embodiments, the front edge 230 may be offset from the front end plane 216. The rear edge 232 extends between the top edge 226 and the bottom edge 228 and is spaced apart from the rear wall 148. In particular, the rear edge 232 is located at a distance D3 from the back panel 214.

[0092] refer to Figures 2 to 4 Window 220 extends in a generally vertical direction, which is substantially parallel to and offset from the central plane 204. In the illustrated embodiment, the top edge 226 of each window 220, 224 follows the curvature of the sidewall 146 because the top edge 226 is closer to the central plane 204 than the bottom edge 228 when the sidewall 146 curves inward from opposite sides 168, 170 toward the top 162. Therefore, the front edge 230 and the rear edge 232 are located at different distances from the central plane 204, and the front edge 230 curves relative to the central plane 204 between the top edge 226 and the bottom edge 228. Similarly, the rear edge 232 curves relative to the central plane 204 between the top edge 226 and the bottom edge 228. In some embodiments, windows 220, 224 may both be offset from the central plane 204 by equal distances.

[0093] It is conceivable that in other embodiments, the size and shape of windows 220 and 224 may be different. Windows 220 and 224 may be tilted relative to the central plane 204, such that the front edge 230 is spaced further from the central plane 204 than the rear edge 232, for example... Figure 3As shown. Therefore, the sidewall 146 tapers between the front end 160 and the rear end 158, such that the sidewall 146 extends from the rear wall 148 at an angle relative to the central plane 204, and in particular, the sidewall 146 may extend outward relative to the central plane 204 in a rear-to-front direction. In some embodiments, the windows 220, 224 may be different in size and shape from one another and located at different positions on the sidewall 146.

[0094] In the illustrated embodiment, the front panel 130 is arcuate or curved. In some embodiments, the front panel 130 is curved outward relative to the sidewall 146, and in particular, the front panel 130 is curved outward from the periphery 184 to the midpoint 200, such that the depth D of the dispenser 110 at a point along the central plane 204 is greater than the depth D at points spaced apart from the central plane 204. In this way, the depth D of the dispenser 110 varies in the left-right or lateral direction. Therefore, the depth of the cavity 142 of the dispenser 110 also varies to allow sufficient space for the installation of boxes of different capacities or types. Furthermore, the curvature of the front panel 130 prevents the box 120 from twisting during use (e.g., when suction or vacuum pressure is applied) when it collapses within the cavity 142, thereby maintaining the alignment and positioning of the box 120 with the windows 220, 224. Furthermore, the curvature of the front panel 130 is substantially uniform in the vertical, top-to-bottom direction spanning the upper segment 188 and the lower segment 192. The trigger 198 mimics the curvature of the front panel 130 to appear flush with the front wall 180. Figure 2 As shown in the best example, the depth D1 of the distributor 110 is generally uniform in the vertical direction.

[0095] In the illustrated embodiment, the front panel 130 and trigger 198 are generally set to be opaque, with a VLT value of 5% or less, such as zero. The rear wall 148 of the body 140 is generally set to be translucent, with a low to medium VLT value greater than that of the front panel 130 (e.g., greater than 5%). The sidewalls 146 of the body 140 include portions having VLT values ​​different from each other, and preferably, the VLT values ​​are greater than 5%. In the illustrated embodiment, the top 162 and transition portion 172 are generally set to be translucent, with low to medium VLT values. Furthermore, opposite sides 168, 170 are set to be translucent between the top 162 and the bottom 164, with low to medium VLT values. Windows 220, 224 are set to be transparent, with high VLT values, and are defined on multiple sides by translucent sidewalls 146. That is, windows 220, 224 have VLT values ​​different from the rest of sidewall 146, and preferably, windows 220, 224 have larger VLT values ​​than the rest of sidewall 146. In some embodiments, windows 220, 224 have VLT values ​​that are approximately twice the VLT values ​​of the rest of sidewall 146, but other configurations are also possible. Thus, the body 140 of distributor 110 has at least two VLT values ​​that are different from each other and greater than 5%.

[0096] Furthermore, the sidewall 146 includes an observation portion 240 and an illumination portion 244 having different VLT values ​​from each other, and more specifically, the observation portion 240 has a higher VLT value than the illumination portion 244. In the illustrated embodiment, windows 220, 224 constitute the observation portion 240, and the remainder of the sidewall 146 constitutes the illumination portion 244, but other configurations are also possible. In some embodiments, the illumination portion 244 may include only the top 162 and transition portion 172 of the sidewall 146, or alternatively, only the top 162, or alternatively, only the transition portion 172. In the illustrated embodiment, the illumination portion 244 includes opposing sides 168, 170 of the sidewall 146 surrounding windows 220, 224, rear wall 148, and bottom end 164. In particular, the illumination portion 244 is provided to be translucent, having a low to medium VLT value in part due to the materials used and the surface treatments applied, while the observation portion is transparent and has a high VLT value.

[0097] Furthermore, the illumination portion 244 and the observation portion 240 define different surface areas from each other. In the illustrated embodiment, the illumination portion 244 defines a larger surface area than the observation portion 240. However, in some embodiments, the illumination portion 244 and the observation portion 240 may define equal surface areas. The surface area defined by the illumination portion 244 is less than the total surface area of ​​the sidewall 146, but preferably greater than about 20% of the total surface area of ​​the sidewall 146. In some embodiments, the illumination portion 244 comprises at least 50% of the total surface area of ​​the sidewall 146 and has a VLT value greater than 5% and less than the VLT value of the observation portion 240.

[0098] Furthermore, the surface area defined by the observation portion 240 is smaller than, but preferably larger than, the total surface area of ​​the sidewalls 146 by about 20%. In the illustrated embodiment, the observation portion 240 comprises at least 30% of the total surface area of ​​the sidewalls 146. It should be understood that the observation portion 240 includes each of windows 220, 224, and therefore, the surface area of ​​the observation portion 240 is equal to the sum of the surface areas of each window 220, 224. Furthermore, the surface area of ​​the observation portion 240 is between about 20% and about 50% of the total surface area of ​​the sidewalls 146. Figure 1-4 In the illustrated embodiment, the observation portion 240 does not include any holes or openings formed therethrough, while the illumination portion 244 includes an opening 174 at the top 162 of the sidewall 146 (see [link]). Figure 4 However, other configurations are also possible. In the illustrated embodiment, windows 220, 224 are discrete and spaced apart from each other on sidewall 146, and each window has a VLT value greater than the VLT value of the illumination portion 244, but other configurations are also possible. In this way, a balance is struck between providing sufficient observation of the box 120 within the dispenser 110 and concealing the interior cavity 142 of the dispenser 110 from view.

[0099] Similarly, the surface area of ​​the front panel 130 of dispenser 110 accounts for at least about 20% and no more than about 50% of the total surface area of ​​dispenser 110. It should be understood that the surface area of ​​the front wall 180 can be from about 10% to about 50% of the total surface area of ​​dispenser 110. Therefore, the front panel 130 is configured to conceal the inner cavity 142 and the housing 120 disposed therein. In this additional manner, a balance is struck between providing sufficient observation of the housing 120 within dispenser 110 and concealing the inner cavity 142 of dispenser 110 from view.

[0100] like Figure 4The diagram shows a top view of the distributor 110. In a first aspect, the illumination portion 244 (which in the illustrated embodiment includes the top 162 of the sidewall 146, the transition portion 172, and the thicker portion of the recessed section 166) is configured to allow ambient light (e.g., artificial or natural) into the cavity 142, but not to allow observation within it. Furthermore, the sidewall 146, particularly the opposing sides 168, 170 on which windows 220, 224 are provided, is depicted as having a curvature in the front-rear direction between the rear end 158 and the front end 160, such that the sidewall 146 is narrower near the rear end 158 than the front end 160. In other words, the sidewall 146 gradually tapers or narrows inward from front to back. Therefore, the windows 220, 224 of the observation portion 240 corresponding to the sidewall 146 are rotated or tilted relative to the central plane 204 away from the front panel 130, such that their rear edge 232 is closer to the central plane 204 than their front edge 230. It is conceivable that the sidewall 146 may taper or narrow gradually in discrete portions (e.g., at the bottom 164), and other configurations are also possible.

[0101] The front panel 130 and the viewing portion 240 are arranged such that multiple viewing areas are defined for a user's advantageous position relative to the dispenser 110 (particularly relative to the central plane 204). It should be understood that, as previously stated, the viewing plane 236 is aligned with a portion of the front edge 230 of each window 220, 224 extending along the front end plane 216. Thus, the viewing plane 236 is parallel to the transverse axis 210 and perpendicular to the central plane 204, as... Figure 4 As shown in the top view. Furthermore, the observation plane 236 is formed at the intersection between a portion of the observation portion 240 and a portion of the illumination portion 244. In one aspect, the actuated observation area 250 is defined adjacent to the front panel 130 and extends radially between a first boundary 252 and a second boundary 254, which are imaginary boundaries schematically shown herein for illustrative purposes. The first boundary 252 and the second boundary 254 intersect the observation plane 236 at the front edge 230 of each of the first windows 220 and the second window 224, thus extending from the front edge 230 of each of the first windows 220 and the second window 224 at the same but mirror angle θ (e.g., 30 degrees) as the observation plane 236. Figure 4The top view is shown. The angle θ is exemplary and corresponds to an approximate range of viewing angles provided by the windows 220, 224 themselves, which is a function of various characteristics of the windows 220, 224 that affect VLT and / or opacity, such as surface treatment, material, coating, wear, etc. Furthermore, the angle θ is limited by the viewing direction P1 of the first window 220 and the viewing direction P2 of the second window 224, where the viewing direction P1 of the first window 220 is orthogonal to the surface of the window 220, and the viewing direction P2 of the second window 224 is orthogonal to the surface of the second window 224. Therefore, the viewing directions P1 and P2 are functions of the angle or curvature of the first window 220 and the second window 224. Thus, when the viewing directions P1 and P2 are changed, for example by pivoting or rotating backward or forward, the angle θ of the first boundary 252 and the second boundary 254 also changes.

[0102] In the actuated observation area 250, observation of the cartridge 120 housed in the cavity 142 of the dispenser 110 is prevented or suppressed by the opaque front panel 130. Preferably, the user-actuated trigger 198 within the actuated observation area 250 is used to dispense fluid rather than to identify a refill status. Thus, the actuated observation area 250 is configured to conceal or obscure the cartridge 120 and the cavity 142 of the dispenser 110, and alternatively, to limit the visibility of the opaque front panel 130.

[0103] Furthermore, an evaluation observation area is defined near the body 140 of the dispenser 110. This evaluation observation area includes a first evaluation area 260 near the first window 220 and a second evaluation area 262 near the second window 224. It should be understood that, as previously described, the rear plane 214 extends parallel to the transverse axis 210 and perpendicular to the central plane 204, as... Figure 4 As shown in the top view. The first evaluation area 260 is defined between a first boundary 252 and a third boundary 266, the third boundary 266 extending from the rear edge 232 of the first window 220 at an angle φ (e.g., 30 degrees) to the rear plane 214, as... Figure 4 As shown in the top view. Similarly, the second evaluation area 262 is defined between the second boundary 254 and the fourth boundary 268, the fourth boundary 268 extending from the rear edge 232 of the second window 224 at an angle φ (e.g., 30 degrees) to the rear plane 214, as... Figure 4 As shown in the top view. Like the first boundary 252 and the second boundary 254, the third boundary 266 and the fourth boundary 268 are imaginary boundaries provided for illustrative purposes and are mirror images of each other around the central plane 204. Furthermore, the angle φ is exemplary and corresponds to an approximate range of viewing angles provided by windows 220, 224 and viewing directions P1 and P2, as described above.

[0104] Furthermore, when the distributor 110 is mounted to an outer wall coplanar with the rear plane 214, the first evaluation area 260 and the second evaluation area 262 can extend radially rearward from the first boundary and the second boundary, respectively, to the outer wall. However, when the distributor 110 is mounted to an external support (e.g., a freestanding mount), the first evaluation area 260 and the second evaluation area 262 can extend radially rearward beyond the rear plane 214.

[0105] In some aspects, a first evaluation area 260 and a second evaluation area 262 are provided for viewing the interior 142 of the cassette 120 and dispenser 110 at least through a first window 220 and a second window 224, respectively. As described above, light is allowed to enter through an illumination portion 244 of the sidewall 146 to illuminate the interior 142 and the cassette 120, and a transparent viewing portion 240 is provided to allow a maintenance professional standing or moving within the first evaluation area 260 or the second evaluation area 262 to see the cassette 120 and the interior 142. In the illustrated embodiment, both the illumination portion 244 (e.g., sidewall 146) and the viewing portion 240 (e.g., windows 220, 224) are located within the first evaluation area 260 and the second evaluation area 262, such that two VLT values ​​are set within the first evaluation area 260 and the second evaluation area 262. Preferably, the maintenance professional within the first evaluation area 260 or the second evaluation area 262 can quickly (i.e., at a glance) identify the refill status of the dispenser 110. Therefore, maintenance professionals will look for either the first assessment area 260 or the second assessment area 262 to determine whether the dispenser 110 needs to be refilled, rather than standing in the actuation observation area 250 or opening the dispenser 110.

[0106] Still referencing Figure 4 The distributor 110 is schematically represented in a top plan view as being circumscribed by a circumference 274 (i.e., 360 degrees) surrounding the distributor 110, with the central plane 204 intersecting the circumference 274 at 0 degrees. As shown, a first boundary 252 intersects the circumference 274 at 60 degrees, and a second boundary 254 intersects the circumference 274 at 300 degrees. Therefore, the actuation observation area 250 extends approximately 120 degrees around the distributor 110. Additionally, a third boundary 266 intersects the circumference 274 at 120 degrees, and a fourth boundary 268 intersects the circumference 274 at 240 degrees. Therefore, the first evaluation area 260 and the second evaluation area 262 each extend approximately 60 degrees around the distributor 110.

[0107] It is conceivable that by further narrowing or tapering the sidewall 146 of the main body 140 inward toward the rear end 158, the third boundary 266 of the first window 220 and the fourth boundary 268 of the second window 224 will be rotated rearward accordingly to change the viewing directions P1 and P2, thereby causing the first boundary 252 and the second boundary 254 to rotate, resulting in a decrease in the associated angle θ, thus expanding the actuated viewing area 250. Similarly, the rearward rotation of the third boundary 266 and the fourth boundary 268 increases the associated angle φ relative to the rear plane 214. In this way, the first evaluation area 260 and the second evaluation area 262 will rotate in the rearward direction, and the actuated viewing area 250 will become wider, for example, greater than 120 degrees. Alternatively, the sidewall 146 may not include the tapered shape between the front end 160 and the rear end 158. Furthermore, the sidewall 146 may taper in the opposite direction. It is also conceivable that the actuated viewing area 250 could be widened by extending the periphery 184 of the front panel 130 further outward than the sidewalls 146 (i.e., away from the central plane 204) to overlap or protrude beyond the sidewalls 146. Alternatively, the actuated viewing area 250 could be increased by offsetting part or all of the windows 220, 224 rearward toward the rear plane 214, specifically by spacing the front edge 230 from the front plane 216, and thus, the viewing plane 236 rearwardly spaced from the front plane 216. By doing so, the first boundary 252 and the second boundary 254 are moved rearward such that the first boundary 252 intersects the circumference 274 at a point greater than 60 degrees, and the second boundary 254 intersects the circumference at a point less than 300 degrees.

[0108] In some embodiments, the interior of the rear wall 148 and / or the front wall 180 may include a reflective material for reflecting visible light passing through the sidewall 146. The reflective material may be integrally disposed with the rear wall 148 or the front wall 180, or it may be applied to the rear wall 148 or the front wall 180, for example, by a reflective adhesive, reflective coating or paint, or reflective panel. The reflective material may reflect visible light back into the cavity 142 of the dispenser 110 to enhance illumination of any box 120 or fluid disposed therein. Reflective materials may be advantageous, whether intentionally or unintentionally, when the dispenser 110 is placed in an environment with limited visible light. For example, in a lavatory provided as part of a park or campsite, artificial light may be provided almost entirely, with only ambient light from the sun or light reflected from the moon being directed into the lavatory. In another example, limited visible light may be intentionally provided to lavatories in various entertainment venues, restaurants, bars, stadiums, etc., for environmental, aesthetic, or energy-saving purposes. Therefore, the distributors 110 are designed to adapt to various environments with a certain range of visible light provided to them, which can be further enhanced by adding reflective material to the rear wall 148 or the front wall 180.

[0109] refer to Figures 5 to 7The box 120 includes an outlet end 280 and a base end 284 opposite to the outlet end 280. The box has a body 288, which includes a front side or front wall 292 opposite to a rear side or rear wall 296, opposing first sidewalls 300 and second sidewalls 304, and a base 308. The front wall 292 and rear wall 296, as well as the first sidewalls 300 and second sidewalls 304, extend from the base 308 to a shoulder 312. The base 308 is located at the base end 284, the shoulder 312 is located at the outlet end 280, and the body 288 extends from the base end 284 to the outlet end 280. In other words, the body 288 extends between the base 308 at the base end 284 and the shoulder 312 at the outlet end 280. The first sidewall 300 and the second sidewall 304 may be collectively referred to as a pair of sidewalls. In the illustrated embodiment, the box 120 is provided as opaque and has a low VLT value of 5% or less. In other embodiments, the box 120 may be partially or completely translucent or transparent, having a VLT value greater than 5%.

[0110] A generally cylindrical neck 316 extends axially from the center of shoulder 312 to define an opening 320 that enters and communicates with the internal volume 324 of housing 120. An annular collar 328 extends around neck 316. Base 308 is disposed opposite neck 316 of housing 120, and the internal volume 324 of housing 120 is generally defined between front wall 292 and rear wall 296, first side wall 300 and second side wall 304, and between neck 316 and base 308. Neck 316 and an annular collar 328 are generally rigid and / or thickened relative to body 288 of housing 120, and thus resist deformation during collapse, provide support when inverted and mounted within dispenser 110, and provide a secure engagement with pump assembly 152 operably attached to neck 316. The vertical axis 332 defining the vertical plane 336 extends centrally through the box 120 between the first sidewall 300 and the second sidewall 304, and intersects the front wall 292 and the rear wall 296. In other words, the vertical plane bisects the box 120, and the box 120 is structurally symmetrical about the vertical plane 336. Furthermore, the front wall 292 and the rear wall 296 arch or bend outward relative to the vertical axis 332 between the first sidewall 300 and the second sidewall 304.

[0111] Still referencing Figure 5-7A shoulder 312 extends at an angle from a neck 316 to each of the front and rear walls 292, 296 and a pair of side walls 300, 304. Specifically, a front shoulder edge 340 is formed where the shoulder 312 intersects with the front wall 292, a rear shoulder edge 344 is formed where the shoulder 312 intersects with the rear wall 296, a first shoulder edge 348 is formed where the shoulder 312 intersects with the first side wall 300, and a second shoulder edge 352 is formed where the shoulder 312 intersects with the second side wall 304. A pair of support ribs 356 extend along the shoulder 312 between the neck 316 and the pair of side walls 300, 304. In one example, each support rib 356 extends from an annular collar 328 to each of the pair of side walls 300, 304. Each support rib 356 protrudes from the shoulder 312 by a varying distance, such that each support rib 356 protrudes a greater distance from the shoulder 312 near the neck 316 than it does near the corresponding first shoulder edge 348 and second shoulder edge 352. In other words, each support rib 356 becomes higher relative to the shoulder 312 as it moves inward relative to the vertical axis 332. The support ribs 356 are provided to resist deformation of the shoulder 312 in the outlet end 280 of the box 120 during use due to collapse. It is conceivable that the support ribs 356 are hollow and open into the interior of the box 120, but other configurations are also possible.

[0112] refer to Figure 7 and Figure 10 The base 308 includes a generally flat base plate 360 ​​surrounded by a base edge 364. Furthermore, as... Figures 5 to 7 As shown, a front base edge 368 is formed at the intersection of base 308 and front wall 292, a rear base edge 372 is formed at the intersection of base 308 and rear wall 296, a first base edge 376 is formed at the intersection of base 308 and first side wall 300, and a second base edge 380 is formed at the intersection of base 308 and second side wall 304. The base plate 360 ​​and base edge 368 resist deformation upon collapse to prevent fluid from becoming trapped within the box 120. Furthermore, the base plate 360 ​​and base 308 are stable and / or thickened relative to the body 288 of the box 120 for additional support and rigidity, for example, when the box 120 is stored upright on the base 308, or during transport or shipping.

[0113] In the illustrated embodiment, a plurality of flat corners 384 are provided in the outlet end 280, between each of the front shoulder edge 340, the rear shoulder edge 344, the first shoulder edge 348, and the second shoulder edge 352, and in the base end 284, between each of the front base edge 368, the rear base edge 372, the first base edge 376, and the second base edge 380. Preferably, the flat corners 384 are configured to have no radius of curvature or a large radius of curvature relative to the vertical axis 332 to prevent fluid from being trapped within the cartridge 120 and thus increase the percentage of fluid dispensed from the cartridge 120.

[0114] Furthermore, the first sidewall 300 and the second sidewall 304 each support a corresponding first valley 388 and a second valley 392. Each of the first valley 388 and the second valley 392 is defined by a top peripheral edge 396, a front peripheral edge 400, a rear peripheral edge 404, and a bottom peripheral edge 408. The front panel 412 extends inward from the front peripheral edge 400 toward the vertical fold line 416, the rear panel 420 extends inward from the rear peripheral edge 404 to the vertical fold line 416, the upper panel 424 extends inward from the top peripheral edge 396 to the vertical fold line 416, and the lower panel 428 extends inward from the bottom peripheral edge 408 to the vertical fold line 416. The vertical fold line 416 is positioned closer to the vertical plane 336 than the top peripheral edge 396, the front peripheral edge 400, the rear peripheral edge 404, and the bottom peripheral edge 408. Furthermore, the vertical fold line 416 extends between the upper joint 432, which connects to the upper pair of angled fold lines 436, and the lower joint 440, which connects to the lower pair of angled fold lines 444. The upper panel 424 extends between the upper pair of angled fold lines 436, and the lower panel 428 extends between the lower pair of angled fold lines 444, with the upper panel 424 defining a smaller surface area than the lower panel 428. However, the front panel 412 and the rear panel 420 define substantially equal surface areas. Both the upper panel 424 and the lower panel 428 are substantially triangular, and both the front panel 412 and the rear panel 420 are substantially trapezoidal, although other configurations are possible. The upper joint 432 is positioned closer to the top outer edge 396 than the lower joint 440, which is positioned closer to the bottom outer edge 408.

[0115] Continue to refer to Figures 5 to 7The front wall 292 and the rear wall 296 each include an upper fold 448 and a lower fold 452, which extend laterally between opposing sidewalls 300 and 304. The upper fold 448 is positioned closer to the outlet end 280, for example, at a distance U1 from the upper part of the base 308, and the lower fold 452 is positioned closer to the base end 284, for example, at a distance U2 from the lower part of the base 308. Furthermore, the upper fold 448 and the lower fold 452 are spaced apart from each other by an intermediate distance U3, which is less than the upper distance U1 and greater than the lower distance U2. The lower distance U2 is less than the upper distance U1. In addition, the upper fold 448 and the lower fold 452 correspond to the upper joint 432 and the lower joint 440 of a pair of sidewalls 300 and 304. The lower sub-panel 456 is disposed between the base 308 and the lower crease 452 on each of the front wall 292 and the rear wall 296. The middle sub-panel 460 is disposed between the upper crease 448 and the lower crease 452 on each of the front wall 292 and the rear wall 296. The upper sub-panel 464 is disposed between the upper crease 448 on each of the front wall 292 and the rear wall 296 and the shoulder 312. The upper sub-panel 464 and the lower sub-panel 456 are angled toward the middle sub-panel 460 in opposite directions, but the middle sub-panel 460 is approximately parallel to the vertical axis 332.

[0116] The upper fold 448 and lower fold 452 of the front wall 292 and the rear wall 296, and the fold lines 416, 436, and 444 of the side walls 300 and 304 are arranged in a pattern that is offset from a uniform interval along the height of the box body 140 in the direction toward the outlet end 280 and / or the shoulder 312. It should be understood that in Figure 12-17 The image depicts a representative box 520, showing the offset distribution of crease lines along the height of the box body 524 and the collapsed shape of the box 120. The offset crease lines are positioned towards the outlet end 280 to prevent fluid from becoming trapped inside and thus not being dispensed. Furthermore, the upper crease 448 and lower crease 452 of the sidewalls 300, 304, as well as the fold lines 416, 436, 444, are configured to prevent the box 120 from twisting or rotating during collapse.

[0117] like Figure 10 As shown, for illustrative purposes, Figure 10The box 120 in a collapsed state is schematically depicted, with a waist 528 formed at a location where the front wall 292 and rear wall 296 converge toward each other and, in some cases, contact each other. The waist 528 is positioned substantially closer to the base 308 than the shoulder 312, for example, approximately one-third of the distance between the base 308 and the shoulder 312, approximately a distance U2 from the base 308. Because the box 120 is inverted during use in the dispenser 110, positioning the waist 528 closer to the base 308 allows for the dispensing of a larger proportion of fluid, thereby preventing waste and increasing the total percentage of fluid dispensed from the box 120. Furthermore, it should be understood that the base 308, flat corner 384, shoulder 312, and neck 316 are generally not deformed in the collapsed state of the illustrated embodiment, thereby preventing fluid from becoming trapped within the box 120. However, as Figure 10 As shown, without departing from the scope of this disclosure, a certain amount of deformation, such as warping or bending, may occur in the base 308 or the shoulder 312.

[0118] In some embodiments, the box 120 is made of a plastic material, but other materials may be used, such as metals, alloys, composites, biodegradable materials, recycled materials, natural materials, etc. Furthermore, the box 120 may be manufactured using a blow molding process, but other manufacturing methods, depending in part on the materials used, may be considered, such as injection molding, thermoforming, welding, 3D printing, and / or additive manufacturing, etc. Additionally, in some embodiments, a label is attached to the box 120, preferably to the front wall 292 or the rear wall 296. The label may display information about the fluid within the box 120, brand and / or marketing information, box type and / or compatibility, and various other suitable and relevant information. The label may be attached to the box 120 using adhesives, fasteners, or other bonding techniques. Alternatively, the label or information may be integrally formed with the box 120.

[0119] refer to Figure 8 and Figure 9 The dispenser 110 includes a support structure 540, which includes a collar 150 having opposing guide protrusions 544 configured to interact with the neck 316 of the cassette 120 when mounted in the cassette 120. In the illustrated embodiment, the cassette 120 includes a corresponding flat portion 548 corresponding to the guide protrusions 544 of the collar 150, thereby allowing the cassette 120 to be received and mounted in one or more predetermined orientations.

[0120] Figures 12 to 17The schematic diagram illustrates the predetermined manner in which the cartridge 520 collapses in various refill states as the amount of fluid in the representative cartridge 520 decreases from 100% full to 80% full, 60% full, 40% full, 20% full, and essentially full when viewed from the side profile of the observation section 240 (e.g., window 220). Figure 12-17 Box 520 represents Figure 5-7 Box 120 is the same, and therefore the same elements are so labeled. In addition, box 520 shares many attributes and features with box 120, and for layout and visual indication purposes, the following description of box 520 is intended to include box 120.

[0121] like Figure 12 As shown, the cavity 142 of dispenser 110 defines a volume at least partially filled by cassette 520. In some examples, when cassette 520 is full, it occupies at least about 60% of the total volume. An unobstructed top space 550 of the cavity 142 is defined between the top 162 of cassette 520 and sidewall 146, and also between transition portions 172, as shown. Figure 12 As shown. Therefore, when the box 520 is full, the top space 550 is exposed to the translucent portion of the sidewall 146, i.e., the illumination portion. When the box 520 is full, the top space 550 includes at least about 5% of the total volume of the inner cavity 142. Then, as the base 308 of the box 520 moves downward away from the top 162 of the sidewall 146 due to the collapse of the box 520 during use, the top space 550 expands, and thus more of the inner cavity 142 becomes unobstructed. Therefore, light entering through the illumination portion 244 of the sidewall 146 fills more of the unobstructed top space 550 to enhance the illumination of the partially or fully collapsed box 520, and in some cases, enhance the liquid level through the interior of the box 520. When the box 520 collapses and occupies less of the inner cavity 142, more light fills the inner cavity 142 above and around the box 520. In this way, dispenser 110 is designed to provide even greater illumination to box 520 when box 520 collapses, where the maximum amount of illumination is provided when most needed (i.e., when box 520 is almost empty), such as Figure 17 As shown.

[0122] refer to Figure 12-17As the fluid in the cartridge 520 is depleted, the fluid fill level 552 gradually moves toward the neck 316 of the cartridge 520. When the cartridge 520 is formed of a transparent or translucent material, the first and second windows corresponding to the viewing portion 240 of the dispenser 110 are configured such that the fluid fill level 552 of the cartridge 520 can be seen through them. In particular, the fluid fill level 552 gradually moves from the top edge 226 of the first window 220 toward the bottom edge 228. This visual indication of the fluid fill level 552 can be generally understood without regard to any particular language.

[0123] exist Figure 12 In the illustrated embodiment, when the fluid fill level 552 is aligned with or near the top edge 226 of the first window 220, this indicates that the cassette 520 is 100% full or nearly full. In other embodiments, this may correspond to the cassette 120 being 20% ​​full, 40% full, 60% full, or 80% full. In the illustrated embodiment, when the fluid fill level 552 is aligned with or near the bottom edge 228, this indicates that the cassette 520 is empty or nearly empty.

[0124] Still referencing Figure 12 When the box 120 is full, the bottom outer edge 408 is substantially aligned with and close to the top edge 226 of the first window 220, partially hidden or concealed behind the translucent sidewall 146 surrounding the first window 220. Similarly, the front wall 292 and the rear wall 296 are positioned further forward and backward than the corresponding front edge 230 and rear edge 232 of the first window 220, respectively, and are therefore hidden and not visible through the window 220.

[0125] On the other hand, visual cues or indicators are provided through the relative position of each window 220, 224 with respect to the box 520 and its visible portion. (Reference) Figure 13 When box 520 is approximately 80% full, it has partially collapsed, causing the bottom outer edge 408 to move downwards and the front wall 292 and rear wall 296 to move inwards toward each other. This movement is noticeable relative to the top edge 226, front edge 230, and rear edge 232 of the first window 220. In this way, regardless of whether box 520 is opaque, translucent, or transparent, the filling state of box 520 can be determined relative to the deformation of the portion of box 520 relative to the first window 220.

[0126] refer to Figure 14When the box 520 is approximately 60% full, the collapse lowers the bottom outer edge 408 significantly further compared to the full state. Therefore, the base 308 of the box 520 is now visible through the first window 220 below the top edge 226, indicating that the gap for the upper visual cue 560 is defined between the top edge 226 and the base 308 of the partially collapsed box 520. Similarly, the rear wall 296 has moved inward toward the front wall 292 to become visible through the first window 220, indicating that the gap for the rear visual cue 564 is defined between the rear edge 232 and the rear wall 296 of the box 520. However, in this state, the front wall 292 of the box 520 remains hidden. Therefore, when approximately 60% full, the two visual cues 560, 564 are provided by the relative positions of the box 520 and the first window 220. It should be understood that when the box 520 collapses from an 80% full state to a 60% full state, for example, respectively in… Figure 13 and Figure 14 As depicted, at least one, but no more than two, of visual cues 560 and 564 are visible through the first window 220. In other words, when the box 520 collapses from a full state to a partially full state (e.g., 60%), at least one, but no more than two, of the front wall 292, rear wall 296, and base 308 are visible through the first window 220.

[0127] Now for reference Figure 15 When the box 520 is approximately 40% full, it has essentially collapsed, thus amplifying the upper visual cue 560 and the rear visual cue 564. Additionally, the front visual cue 568 is positioned in a gap between the front wall 292 of the box 520 and the front edge 230 of the first window 220, since the front wall 292 has become at least partially visible through the first window 220. Therefore, when the box 520 is approximately 40% full, three visual cues 560, 564, and 568 are provided by the relative positions of the box 520 and the first window 220. In other words, when the box 520 is collapsed to a 40% full state, the front wall 292, the rear wall 296, and the base 308 are visible through the first window 220. For simplicity, it should be understood that when the box 520 is collapsed to... Figure 16 The 20% full state shown and Figure 17 In the empty state shown, the three visual cues 560, 564, and 568 become increasingly larger.

[0128] Therefore, in addition to or in lieu of fluid fill level 552, visual cues 560, 564, and 568 are generally recognized and understood to correspond to the refill status. Thus, visual cues 560, 564, and 568 are not limited by language or other communication barriers that may vary among maintenance professionals. In this way, dispenser 110 and boxes 120 and 520 are suitable for compatibility in any country or region worldwide.

[0129] It is also conceivable that boxes 120, 520 and / or dispenser 110 may be equipped with markings, signs, colors and / or contrasting colors, and other visual indicators to facilitate maintenance professionals in identifying the refill status. It is also conceivable that windows 220, 224 may be colored to filter or interact with the colors or textures of boxes 120, 520 to enhance or highlight the visibility of the refill status therein.

[0130] In some implementations, windows 220, 224, or portions thereof, may be configured with magnification to improve visibility of fluid fill level 552, cartridges 120, 520, and / or any properties associated with the fluid itself from a distance, or simply to allow for easier visualization while standing or moving within evaluation areas 260, 262. The magnification may be 2x, 3x, 4x, 10x, 50x, or any other suitable size.

[0131] Furthermore, it is conceivable that windows 220, 224 and / or sidewalls 146 may be textured or patterned on their inner and / or outer surfaces to further limit or reduce visibility of evaluation areas 260, 262 through windows 220, 224. For example, anticipating that dispenser 110 may be mounted near a mirror, such as in a washroom, windows 220, 224 may be textured to prevent the boxes 120, 520, fluid filling level 552, and cavity 142 from being visible through reflections in the mirror. In some cases, a coating or substrate may be applied to the observation portion 240, i.e., windows 220, 224, to diffuse or scatter light propagating at a specific angle toward the observation portion 240. For example, a coating or substrate may be provided to narrow the first evaluation observation area 260 and the second evaluation observation area 262, or to prevent visibility through mirror reflections when dispenser 110 is located near or between mirrors.

[0132] In the embodiments described herein, the first window 220 and the second window 224 are substantially identical and positioned on opposite sides of the distributor. However, in other embodiments, the first window 220 and the second window 224 may be configured differently. (See reference...) Figure 18-20Alternative embodiments of the lighting portion 244 of the side wall 146 of the main body 140 and the observation portion 240 of one of the windows 220, 224 are depicted as having varying sizes and shapes and being in varying positions and arrangements.

[0133] refer to Figure 18 The diagram illustrates an observation section 600 arranged vertically along an illumination section 244 in the form of an array of window slits 620. The window slits 620 are shown as being approximately equidistant from each other and centrally positioned between the front end 160 and rear end 158 of a side wall 146, which constitutes the illumination section 244. As shown, each window slit 620 is spaced apart from the front panel 130, which further expands the actuated observation area 250 in front of the dispenser 110 and narrows the evaluation areas 260, 262. Furthermore, each window slit 620 is defined on all sides by the illumination section 244. Additionally, when the cartridge 120 is full, the cartridge 120 and / or the fluid fill level 552 are visible through all window slits 620, and the window slits 620 gradually decrease as the cartridge 120 collapses and the fluid fill level 552 decreases during use. Markings may be provided on the side wall 146 and / or the window slits 620 to correspond to well-known full and empty symbols.

[0134] refer to Figure 19 The diagram illustrates an observation portion 700 arranged along an illumination portion 244 in the form of an array of window slits 720. In the illustrated embodiment, each of the window slits 720 is defined by the illumination portion 244 on all sides. The window slits 720 have different sizes and shapes, with a surface area increasing in the downward direction to provide greater visibility when the cartridges 120, 520 and / or the fluid fill level 552 are near empty, and to provide less visibility when the cartridges 120, 520 and / or the fluid fill level 552 are full.

[0135] refer to Figure 20 The observation section 800 is arranged along the illumination section 244 in the form of a conical window 820. Furthermore, the conical window 820 is defined by the illumination section 244 on all sides. The conical window 820 is narrower towards the top 162 and wider towards the bottom 164, thereby allowing greater visibility when the boxes 120, 520 and / or the fluid-fill level 552 are nearing an empty state.

[0136] In some environments, multiple distributors are positioned along a single wall. The distributor 110 of this disclosure is configured to allow such a series of distributors 110 to share one or more common assessment areas 260, 262 from which maintenance professionals can simultaneously determine the remaining fluid volume in multiple distributors 110, which saves time and is more efficient.

[0137] refer to Figure 21 The alternative box 900 is shown, which is similar to the one mentioned above. Figure 5-7 Box 120 is described, therefore only the differences will be described below. Figure 21 In one embodiment, the neck 904 of the cartridge is provided with threads 908, allowing it to be screwed onto any suitable dispensing mechanism for dispensing fluid from the cartridge 120. The neck 904 of the cartridge 120 is provided with a tamper-proof feature in the form of a ratchet 912, which prevents the dispensing mechanism from being unscrewed once attached to the cartridge 120. The support rib 916 (opposite rib not shown) is similar to the support rib 356 described for the cartridge 120; however, the support rib 916 of the cartridge 120 is thinner in width and has a lower profile, so that the support rib 916 does not trap fluid when using more viscous fluids. It should be understood that in the cartridge 900, the support rib 916 includes a hollow structure leading to the interior of the cartridge, but in some embodiments, the support rib 916 may be solid.

[0138] Although one or more preferred embodiments have been described, it should be understood that various changes or modifications may be made without departing from the scope defined by the appended claims.
