The present disclosure generally relates to the field of dispensers and, more particularly, it relates to a dispenser for rolled products such as rolled paper products.
Several types of rolled product dispensers exist in the prior art. These systems are used to gradually provide to a user of the dispenser different types of products rolled around a hollow center portion, hereinafter referred to as a “rolled product”. The most common of these dispensers dispenses paper items such as paper towels and toilet paper. These dispensers are often used in public area washrooms.
Already known in the prior art are rolled product dispensers provided with fitting pieces, such as bushings, permanently or removably placed in an extremity of the hollow center portion of the rolled products to prevent rolls from being misplaced or installed onto an incompatible dispenser.
Further types of known rolled product dispensers are used to discriminate against incompatible and unwanted rolled products, for example, to better control quality and reduce maintenance costs. Another purpose of this type of dispenser is to ensure a sale's exclusive right for roll replacement. Systems designed to discriminate against unwanted rolled products or dispensers are generally referred as “captivity systems.”
It is advantageous for several different reasons, including quality control, reduced maintenance and repair costs for dispensers, to further develop “captivity systems” for rolled product dispensers so that rolled product dispensers can only operate with rolled products specifically designed for use in the dispensers, and so that rolled products can only operate with specifically designed dispensers. Although, various prior art devices have been developed in recent years for this specific purpose, there is still a need for improved captivity systems, which can reduce the occurrences of damage to the dispenser caused by the installation of an incompatible roll product in the dispenser.
It is therefore an aim of the present disclosure to at least partially address the above-mentioned need.

In the following description, although the embodiments of a bushing, a support member including a rolled product connector, and a rolled product dispenser and corresponding parts thereof consist of certain geometrical configurations as explained and illustrated herein, not all of these components and geometries are essential and thus should not be taken in their restrictive sense. It is to be understood, as also apparent to a person skilled in the art, that other suitable components and cooperation thereinbetween, as well as other suitable geometrical configurations, may be used for the bushing, the rolled product connector, and the rolled product dispenser, as will be briefly explained herein and as can be easily inferred herefrom by a person skilled in the art. Moreover, it will be appreciated that positional descriptions such as “above”, “below”, “left”, “right” and the like should, unless otherwise indicated, be taken in the context of the figures and should not be considered limiting.
In the following description, the same numerical references refer to similar elements. Furthermore, for the sake of simplicity and clarity, namely so as to not unduly burden the figures with several references numbers, not all figures contain references to all the components and features, and references to some components and features may be found in only one figure, and components and features of the present disclosure which are illustrated in other figures can be easily inferred therefrom. The embodiments, geometrical configurations, materials mentioned and/or dimensions shown in the figures are optional, and are given for exemplification purposes only.
As will be explained below in relation to various embodiments, the present disclosure describes a captivity assembly 1 (
Referring to the
The rolled product dispenser 50 includes a housing 55 (only a portion thereof being shown in
The dispenser 50 is configured to dispense lengths of the web of the rolled product 10 to a user. The rolled product 10 rotates about its rotation axis, supported by the support members 54, 56.
Again referring to the embodiment illustrated in
It is appreciated that the expression “hollow center portion”, as used herein with regard to the roll of web material 11, is to be understood as a cavity (or at least a partial cavity) having a substantially cylindrical shape defined about a longitudinal axis of the roll of web material 11. According to one embodiment, the rolled product 10 includes a core, i.e. a tubular support about which the web material is wound and which is commonly known in the tissue products industry as a paper roll “core”. The paper roll core is generally made of cardboard material but it could be made of any other suitable material. According to another embodiment, the rolled product 10 is exempt of a physical core. The hollow center portion 12 is particularly defined by the web material wound around itself to obtain the rolled product 10 such that a cavity is formed about its longitudinal axis, which is commonly known in the paper dispensing industry as a “coreless” rolled product 10. Regardless of whether the rolled product 10 embodiment has a core or is coreless, the bushing 20 can be press-fitted in the opposite extremities 14 of the hollow center portion 12 of the rolled product 10, particularly to engage an inner edge thereof. For the sake of simplicity, only the support member referenced as 54 will be described hereinafter but it is worth mentioning that if the other extremity of the hollow center portion 12 was provided with another one of the bushing 20, the support member referenced 56 could feature the same characteristics as support member 54 described below. In a non-limitative embodiment, the two support members 54, 56 can be characterized by a different shape and/or a different configuration.
It is worth mentioning that the cylindrical body 22 of the bushing 20 can be press-fitted (i.e., engaged) in either one or both of the extremities 14 of the hollow center portion 12 without departing from the scope of the present disclosure.
It should be noted that the illustrative dispenser shown in
The bushing 20 of the captivity assembly 1 will now be described in more details. Referring to
The end wall 28 at least partially closes the extremity 14 of the hollow center portion 12 when the bushing 20a is engaged therewith. In the non-limitative embodiment shown, a diameter of the end wall 28 is slightly greater than a diameter of the cylindrical body 22.
In the description and in reference to the bushing 20, the terms “outwardly” and “inwardly” refer to a position of a component of the bushing 20 when mounted into the extremity 14 of the hollow center portion 12, with a position of the hollow center portion 12 as a reference point, and with “outwardly” meaning away from the hollow center portion 12, or alternatively meaning towards the support member 54 if the bushing 20 is engaged therewith. The term “centrally”, as it is used herein, refers to a position of a component of the bushing 20 towards a center thereof (or a rotation axis of the bushing 20 when mounted into the hollow center portion 12) as a reference point and with “peripherally”/“periphery” meaning away from the center of the bushing 20.

Turning now to
The bushing 20a contains five apertures 39 defined in the annular planar wall section 32 of the end wall 28 (excluding the pin-receiving hole 36) peripherally to the pin-receiving hole 36. It is appreciated that these apertures 39 defined in the bushing 20a do not contribute to the captivity of the assembly. Therefore, the shape, the configuration, and the number of apertures 39 defined in the end wall 28 can vary from the embodiment shown to be higher or lower. In an alternative embodiment (not shown), the bushing 20a can be free of apertures provided peripherally to the pin-receiving hole 36.

Referring back to
The curved rib 40a substantially follows the shape of the letter “C” 40a (hereinafter, the “C-shaped rib” 40a). In other words, the C-shaped rib 40a conforms to the shape of a ring characterized by a rib radius “r” wherein an arc of the ring is removed, and the area that corresponds to the removed arc of the ring defines an opening 41. As explained in more details below, the opening 41 has a length (i.e., a length of the missing arc of the C-shaped rib 40a) longer than a diameter of a widest portion of the pin 70 of the support member 54 (see
As it will be described in more details below, the size, the shape, and the location of the curved rib 40 can dictate the captivity of the bushing 20. The size of the bushing 20 includes its height (i.e. its axial depth) and its thickness. The location of the curved rib 40 on the end wall 28 of the bushing 20 can be characterized by the rib radius “r” (i.e. its location on the end wall 28 with respect to a center of the pin-receiving hole 36). It is appreciated that the shape, the location, and the size of the curved rib 40 can vary from the non-limitative embodiments shown herein.

In the description and in reference to the support member 54, the terms “outwardly” and “inwardly” refer to a position of a component of the support member 54 with respect to a center of the rolled product connector 65 as a reference point, with “inwardly” meaning toward the center of the rolled product connector 65 and “outwardly” meaning away from the center of the rolled product connector 65.
Still referring to
The recess 67 is defined by an outer wall structure 80, a platform 60, and a base wall 58 connecting the outer wall structure 80 to the platform 60 at a bottom of the recess 67. Thus, both the outer wall structure 80 and the platform 60 protrudes from the base wall 58. The pin 70, which will be described in more details below in reference to
Thus, the outer wall structure 80, the platform 60 and the pin 70 project (i.e., extend) from the base wall 58 and the outer wall structure 80 surrounds the platform 60 and is spaced-apart therefrom by the recess 67. In the non-limitative embodiment shown in
The outer wall structure 80, the platform 60, and thus the recess 67 surrounding the platform 67 are configured to discriminate against any incompatible bushing 20 by creating an interference with their curved rib 40, either upon engagement of the bushing 20 with the rolled product connector 65 and/or during rotation of the bushing 20 about the pin 70. For instance, if the curved rib 40 of a bushing 20 is characterized by an outer radius “R” (
On the contrary, if the curved rib 40 of a bushing 20 is characterized by an inner radius “r” smaller than a minimal acceptable radius, the curved rib 40 will interfere with the platform 60, preventing at least partially its engagement within the recess 67 and the engagement of the pin 70 within the pin-receiving hole 36 of the bushing 20. The term “inner radius” “r” as used herein with respect to the curved rib 40 corresponds to the distance from the center of the pin-receiving hole 36 to an inner wall surface of the curved rib 40. In other words, the inner radius “r” is equal to the difference between the outer radius “R” and the thickness of the curved rib 40. Therefore, the platform 60 controls the minimal acceptable radius of the curved rib 40 of the complementary bushing 20.
The minimal and maximal acceptable radii are respectively the minimal inner radius and the maximal outer radius that the curved rib 40 of the bushing 20 can have to be engageable with a corresponding rolled product connector 65 as described herein.
Therefore, the curved rib 40 of an incompatible bushing, either having a greater or smaller diameter, a greater thickness and/or a greater height, cannot be inserted in the recess 67 and thereby prevent proper coupling of the bushing 20 with the rolled product connector 65.
For instance, regarding the height, if the curved rib 40 is too high, i.e. it protrudes too much from the planar wall portion 34 with respect to a depth of the recess 67 of the rolled product connector 65, the pin 70 of the rolled product connector 65 cannot fully engage with the pin-receiving hole 36 of the bushing 20 to reach for instance a coupled configuration as shown in
It is also appreciated that other parts of the bushing 20 can interfere with the rolled product connector 65 and vice-versa.
In the embodiment shown, the inner peripheral wall 82 of the platform 60 can be divided into a lower side wall 64 and an upper side wall 62. In the embodiment shown in
It is appreciated that, with regard to the radius of the lower side wall 62, it can have substantially the same radius as the inner radius “r” of the curved rib 40 of a complementary one of the bushings 20. In an embodiment, the center of the arc of the circle of the lower side wall 62 can be offset slightly upwardly from the center of the pin 70. In another embodiment, the radius of the lower side wall 62 can be slightly smaller than the inner radius “r” of the curved rib 40 of a complementary one of the bushings 20 with their centers being concentric.
Other non-limitative embodiments of the rolled product connector 65 are described below in reference to
Turning to
In the embodiments wherein the outer wall structure 180 surrounds partially the platform 160, the recess 167 corresponds to a volume above the base wall 158 delimited by the outer wall structure 180 when present and the platform 160. The recess 167 surrounds the platform 160 and has a width corresponding at least to a distance between the platform 160 and the outer wall structure 180 along a horizontal axis. When the outer wall structure 180 includes two sections 180′, 180″, the distance is the one between a closest one of the sections 180′, 180″ and the platform 160.
In embodiments wherein the platform does not surround the pin, such as the one shown in
As in other embodiments, the distance between the outer wall structure 180 and the platform 160 and a radius of the platform 160 for the section including the lower side wall 162 delimit the compatible bushings 20 and, more particularly, the rib radii of the curved ribs 40 engageable in the recess 167 in an “insertion” configuration and an “offset” configuration, as will be described in more details below.
In the embodiment wherein the outer wall structure 180 has a stepped profile, as shown in
It is appreciated that, in an alternative embodiment (not shown), the outer wall structure 180 of the rolled product connector 165 can include a single section on one lateral side of the platform 160 (e.g., either section 180′ or section 180″). One lateral section of the outer wall structure 180 would suffice to discriminate against a curved rib of a bushing having a radius too great by imposing the maximal acceptable radius.
Referring now to
In the present embodiment wherein the ends of the platform 260 are truncated, the recess 267 still surrounds the platform 260 with a width corresponding to a distance a closest one of the opposite sections of the outer wall structure 280′, 280″ and the truncated platform 260 along a horizontal axis and, more particularly, a location of the step closer to the platform 160.
To engage the recess 267 of the rolled product connector 265 as intended herein, the corresponding curved rib 40 of the bushing 20 should have an outer radius “R” smaller than the maximal acceptable radius, and an inner radius “r” greater than the minimal acceptable radius, as explained above. The boundaries of the recess 267, delimitated by the outer wall structure 280 and the inner peripheral wall of the platform 260 (more particularly the lower side wall 262), define the maximal and minimal acceptable radii of the curved rib 40.
In the embodiment shown, a distance between an edge of the nearest section of the wall structure 280′, 280″ and a center of the pin 270 (depicted as the distance “a”) corresponds to the maximal acceptable radius that the outer radius “R” of the curved rib 40 can have to be insertable in the recess 267 without interfering with the outer wall structure 280.
The distance between the nadir 269 of the lower side wall 264 of the platform 260 with respect to the center of the pin 270 (depicted as the distance “b”) can determine the minimal acceptable radius for the inner radius “r” of the curved rib 40, i.e. the minimal radius that the inner radius “r” can have to be engageable in the recess without interfering with the platform 260 upon engagement of the bushing 20 with the pin 70 when they are concentric. It should be noted that the principles of the minimal and maximal acceptable radii as exemplified in respect to the recess 267 embodiment shown in

Non-limitative embodiments of the rolled product connector 65, 165, 265, 365, 465 have been described. It is appreciated that the shape and the configuration of the rolled product connector 65, 165, 265, 365, 465 can vary from the embodiments shown. For instance and without being limitative, the shape and the size of the pin 70, 170, 270, 370, 470, the platform 60, 160, 260, 360, 460, and the outer wall structure 80, 180, 280, 380, 480 can vary, provided that their relative configuration, size and shape limit the bushings that can be mounted thereto.
The following paragraphs describes the interaction between the bushing 20 and the support member 54, 154, 254, 354, 454 with reference to
When the rolled product 10 including the proprietary bushing 20 is mounted onto the support member 54 including the rolled product connector 65, the bushing 20 is initially engaged with the rolled product connector 65, as shown in
In the “offset” configuration, the curved rib 40 is inserted in the recess 67 of the rolled product connector 65. Since
Thus, for the rolled product 10 being rotatable about the rolled product connector 65 when engaged therewith, the inner radius “r” of the curved rib 40 of the bushing 20 is selected not to interfere with the inner peripheral wall 82 of the platform 60, including the lower side wall 62 and the upper side wall 64. In an embodiment, the inner radius “r” of the curved rib 40 of the bushing 20 is greater than the distance “b” (
Furthermore, upon engagement of the bushing 20 with the rolled product connector 65 and rotation of the bushing 20 about the rolled product connector 65, the curved rib 40 should not interfere with any other component of the rolled product connector 65. Thus, the bushing 20 should be freely rotatable about the pin 70 of the rolled product connector 65, i.e. the curved rib 40 of the bushing 20 should not interfere with the components of the rolled product connector 65, such as the outer wall structure 70 and the platform 60 during rotation. For instance and without being limitative, a distance between an apex of the upper side wall 64 of the platform 60 and a center of the pin 70 should be smaller than the inner radius “r” of the curved rib 40 of the bushing 20 to prevent interference upon engagement of the bushing 20 with the rolled product connector 65.
As mentioned above, the curved rib 40 includes at least one opening 41 which length is greater than a diameter of the pin 70 and, more particularly, at least a diameter of the head 72 of the pin 70. Upon rotation of the rolled product 10 onto the pin 70, the bushing 20 having an incompatible shape and/or configuration respective to the rolled product connector 65 would not engage the rolled product connector 65 as it is intended to.
It is understood that a curved rib 40 embodied as a closed ring (not shown) would be compatible with a dispenser rolled product connector 65 disclosed herein provided the appropriate dimensions. However, an only partially circled rib presenting one or more openings 41 defined between adjacent rib segment extremities as shown in
The captivity features of the support member 54 and its rolled product connector 65, including the base wall 58, the pin 70, the outer wall structure 80, the platform 60 or any combination thereof can be manufactured from a single mold, whether it concerns injection molding, compression molding or any plastic molding method commonly used. For instance, the embodiments of the support member 54 shown in
A rolled product, including the bushing 20 having a curved rib as disclosed above, may not properly fit all rolled product dispensers. More particularly, the bushing 20 is designed for specific rolled product dispensers. To some extent, this constraint ensures that a rolled product equipped with a bushing as disclosed above generally cannot be mounted properly on a different dispenser provided with another type of rolled product connector. This system can result in a form of quality control as there is a reduction of maintenance and repair costs for the dispensers. Occurrences of damage caused to a dispenser through installation of an incompatible roll product in the dispenser can be reduced since the dispenser can only function properly when a compatible rolled product having an appropriate bushing is mounted therein.
The benefits of the roll dispenser 50 and associated bushing 20 disclosed herein may not limited to captivity, as this assembly 1 shows other practical advantages. For example, it was revealed during testing that the combination of the roll dispenser 50 captivity system embodied in
