Patent Description:
For example, when servicing dispensers containing oversized rolls of materials, service personnel must enter the bathroom stall with a new full roll of bath tissue and keys for opening the dispenser. After opening the dispenser, the service personnel must move a partially used stub roll from the primary position before loading the new full roll. Additionally, the service personnel may have to remove a previously dispensed core. It is difficult if not impossible for service personnel to perform these actions while holding the new full roll given the oversized nature of such rolls. In such cases, it is not desirable put the new roll down either on the toilet or the floor of the restroom for hygienic reasons.

In view of the above, a need exists for a dispenser that allows for replacement of the used roll with a new roll of material that can be accomplished without exposing the new roll of material to contamination. Documents <CIT> and <CIT> describe dispensers whereby the partially used stub roll is transferred by gravity or by the service personnel to a second dispensing position inside the dispenser thereby allowing refilling the dispenser with a new roll.

In general, the present disclosure is directed to a dispenser that can facilitate easier removal of stub rolls and installment of new rolls of material. In one embodiment, the dispenser includes a housing having a rear housing and an openable cover that defines a housing interior. The housing interior is configured to receive a roll of material having a diameter. The roll of material may include an oversized or jumbo roll of material. The rear housing includes a backplate to be mounted to a mounting surface, such as the stall wall of a commercial restroom. The housing interior is configured to receive and hold a roll of material in a first dispensing position and a second dispensing position. The dispenser further includes a roll transfer apparatus. Upon the diameter of roll of material reaching a transfer diameter size, the roll transfer apparatus facilitates movement of the roll of material from the first dispensing position to the second dispensing position.

Certain embodiments provide a roll transfer apparatus including a transfer arm configured to hold the roll of material in a first dispensing position. The transfer arm includes a first end having a transfer arm roller configured to engage the roll of material and a second end engaged with a transfer disk. The transfer apparatus also includes a transfer latch having a first end configured to engage the transfer disk. When the diameter of the roll of material reaches a certain transfer diameter size, the second end of the transfer arm engages the first end of the transfer latch in such a manner that causes the transfer latch to disengage from the transfer disk to facilitate movement of the roll of material from the first dispensing position to the second dispensing position. The transfer disk includes a notch configured to securely engage the transfer latch when the jumbo roll is in the first dispensing position. The transfer disk also includes a spring engagement mechanism configured to be secured to an extension spring located on a recessed portion of the backside of the rear housing. The transfer disk also includes a transfer disk protrusion that is configured to engage a transfer disc control slot that is located in the backplate of the rear housing. When the hook disengages from the notch, the extension spring rotates the transfer disk to an extent permitted by the transfer disc control slot, which forces the transfer arm roller against the roll of material, thus, facilitating movement of the roll of material from the first dispensing position to the second dispensing position. The transfer disk and transfer latch can be securely attached to the first side of the backplate that generally forms and faces the housing interior.

In some embodiments, the dispenser includes one or more rollers and a ramp configured to facilitate moving the roll of material from the first position to the second position. The ramp may have an opening to allow for dispensing of the material from the jumbo roll. The ramp generally includes a first end located in closer proximity to the roll of material in the first dispensing position and a second end located closer in proximity to the roll of material in the second dispensing position. The first end of the ramp is elevated in comparison to the second end of the ramp to allow for gravitational forces to further facilitate movement of the roll of material from the first dispensing position to the second dispensing position.

In certain embodiments, the roll of material can be supported by a stub roll support base and an upper stub roll support member when the roll of material is in the second dispensing position.

The housing of the dispenser can also include an access opening configured to permit a user to access a sheet of material from the roll of material. The access opening may define a perimeter having one or more tear members situated along at least a portion of the perimeter. The tear members can facilitate tearing of the material from the jumbo roll, such that it can then be utilized by the end user. The roll of material can include a jumbo roll of toilet tissue.

In embodiments, the dispenser includes a locking mechanism for locking the openable cover to the rear housing. The openable cover can be attached to the rear housing via a hinge.

Also provided herein are methods for installing or replacing a roll of material from a dispenser.

A full and enabling disclosure of the present disclosure is set forth more particularly in the remainder of the specification, including reference to the accompanying figures, in which:.

It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only.

The present disclosure is generally directed to a dispenser for a dispenser for a roll of material. More particularly, the present dispenser is directed to a dispenser that includes a roll transfer apparatus for moving a roll of material from a first dispensing position to a second dispensing position. Moving the roll of material from the first dispensing position to the second dispensing position allows for restroom personnel to more easily install or replace jumbo rolls of material in the dispenser. When the roll of material is located in the second dispensing position, the first dispensing position is available for accepting a new roll of material. Accordingly, when the restroom personnel opens the cover of the dispenser, they can easily insert a new roll of material in the first dispensing position without having to first remove the partially used roll, also referred to as a stub roll. For other dispensers where the stub roll must first be removed, the washroom personnel must set the new roll of material down on a surface in the restroom. This is undesirable because it can introduce contaminants to the new roll of material. However, the disclosed dispenser eliminates the need to sit the new roll of material down while removing the stub roll from the dispenser. Furthermore, the dispenser disclosed herein allows for easier replacement of the partially used roll, which can save time for restroom personnel. In commercial restrooms having multiple jumbo roll dispensers, the time to service and replace partially used rolls can be greatly reduced allowing the restroom personnel to more efficiently service the commercial restroom.

Furthermore, the disclosed dispenser includes a first dispensing position and a second dispensing position, that can assist with eliminating waste in the form of unused product, such as toilet paper, that may be on the partially used roll. For example, many known jumbo roll dispensers only have one dispensing position for the roll of material. Accordingly, when using known dispensers, the washroom personnel must remove the partially used roll in order to refurnish the dispenser with a new roll of material. Material remaining unused on the stub roll generates product waste and economic loss. In certain situations where the partially used roll still contains a decent amount of material, the restroom personnel must decide whether to replace the partially used roll or not. In situations where the partially used roll is not removed, the roll may become fully depleted before the restroom personnel can make it back to replace the partially used roll with a new roll. Having fully depleted rolls is undesirable as there is no product available to the user. The present dispenser, however, eliminates this problem. For instance, the product transfer apparatus automatically transfers the partially used roll to a second dispensing position once the roll reaches a certain diameter. Product is still able to be dispensed from the second position and the restroom personnel is free to provide a new roll of material in the first dispensing position. Accordingly, material can be fully removed from the partially used roll in the second dispensing position and then product can be accessed from the roll in the first dispensing position.

In one embodiment, the dispenser includes a rear housing and an openable cover defining a housing interior. The housing interior is configured to receive a roll of material having a diameter. The rear housing includes a backplate that is configured to be mounted to a mounting surface. The housing interior is configured to receive and hold a roll of material in a first dispensing position and a second dispensing position. The dispenser also includes a roll transfer apparatus. The roll transfer apparatus is located in the interior housing. Upon the diameter of the roll of material reaching a transfer diameter size, the roll transfer apparatus facilitates movement of the roll of material from the first dispensing position to the second dispensing position. The roll transfer apparatus includes a transfer arm configured to hold the jumbo roll in a first dispensing position. The transfer arm includes a first end having a transfer arm roller configured to engage the roll of material and a second end engaged with a transfer disk. The roll transfer apparatus also includes a transfer latch having a first end including a hook configured to engage the transfer disk. Upon the roll of material reaching the transfer diameter size, the second end of the transfer arm engages the transfer latch such that the hook disengages from the transfer disk to facilitate movement of the roll of material from the first dispensing position to the second dispensing position.

For example, when the hook <NUM> of the transfer latch <NUM> is securely engaged with the notch <NUM> of the transfer disk <NUM>, the transfer disk protrusion <NUM> is generally secured in the first end <NUM> of the control slot. As the second end <NUM> of the transfer arm <NUM>, pushes the hook <NUM> of the transfer latch <NUM> out of engagement with the notch <NUM> of the transfer disk, the energy of stored in the extension spring <NUM> will rotate the transfer disk <NUM>. However, the transfer disk <NUM> rotation is stopped once the transfer disk protrusion <NUM> reaches the second end <NUM> of the transfer disk control slot <NUM>.

Referring to <FIG>, the dispenser <NUM> also includes one or more rollers <NUM> situated along the bottom of the housing interior <NUM> for facilitating movement of the roll of material <NUM> from the first dispensing position <NUM> to a second dispensing position <NUM>. As shown in <FIG>, the dispenser <NUM> also includes a ramp <NUM> having a ramp opening <NUM>. Material from the roll of material <NUM> may be dispensed through the ramp opening <NUM>. The ramp <NUM> can be located between one or more rollers <NUM>. The ramp opening <NUM> can also be positioned above the housing access opening <NUM> such that the product can be dispensed from the housing access opening <NUM>. The ramp <NUM> has a first end <NUM> and a second end <NUM>. The first end <NUM> is closer in proximity to the roll of material <NUM> when it is in the first dispensing position <NUM>. Th second end <NUM> of the ramp <NUM> is in closer proximity to the roll of material <NUM> when it is in the second dispensing position <NUM>. The first end <NUM> is elevated in comparison to the second end <NUM> in order to facilitate movement of the roll of material <NUM> from the first dispensing position <NUM> to the second dispensing position <NUM>. Once the partially depleted roll is on top of the ramp <NUM>, the slope of the ramp <NUM> will facilitate allowing the partially depleted roll of material <NUM> to move into the second dispensing position <NUM>.

Referring now to <FIG>, the dispenser <NUM> includes a housing access opening <NUM> having a housing access opening perimeter <NUM>. The housing access opening <NUM> can have one or more tear members <NUM> situated about the housing access opening perimeter <NUM> to facilitate tearing and removal of the material product form the jumbo roll. In some embodiments, the one or more tear members <NUM> may include serrated molded plastic teeth suitable for separating material product from the roll of material <NUM>.

As shown in <FIG>, the dispenser <NUM> includes a housing interior <NUM> capable of holding the roll of material <NUM> in a first dispensing position <NUM> and a second dispensing position <NUM>. The dispenser of <FIG> is empty and does not have a roll of material <NUM> inserted therein. <FIG> illustrate the movement of a roll of material <NUM> from the first dispensing position <NUM> to the second dispensing position <NUM>. Referring to <FIG>, when restroom personnel load a new roll of material into the dispenser <NUM> they must move the transfer arm <NUM> fully in the direction of Arrow X, which stretches the extension spring <NUM> and allows the transfer latch <NUM> to engage the notch <NUM> of the transfer disk <NUM>, thus locking the transfer disk <NUM> in place and storing energy in the extension spring <NUM>. As shown, a portion of the roll of material <NUM> may rest on one or more rollers <NUM> in order to assist removal of product from the roll of material <NUM>. The roll of material <NUM> generally has a diameter "D" that decreases as product is removed from the roll. As shown, when the roll of material <NUM> is in the first dispensing position <NUM>, the transfer arm roller <NUM> is also in contact with the roll of material <NUM> when it is in the first dispensing position.

Referring now to <FIG>, as the transfer arm <NUM> and the transfer arm roller <NUM> track with decreasing product roll the transfer arm <NUM> moves in the direction of Arrow A. The movement of the transfer arm <NUM> in the direction of Arrow A causes the second end <NUM> of the transfer arm <NUM> extending above the transfer arm pivot <NUM> to move in the direction of Arrow B, which causes the transfer latch <NUM> to gradually move out of engagement with the transfer disk <NUM>. When the roll of material <NUM> reaches a transfer diameter size, the second end <NUM> of the transfer arm <NUM> will have moved the transfer latch <NUM> completely out of engagement with the transfer disk <NUM>. Once the transfer latch <NUM> is disengaged from the transfer disk <NUM>, the extension spring <NUM> can return its stored energy to the transfer apparatus system thus rotating the transfer disk <NUM> to the extent permitted by the transfer disk protrusion <NUM> and the transfer disk control slot <NUM>. The release of the extension spring <NUM> forces the transfer arm <NUM> against the partially depleted roll of material <NUM>, thus driving the roll of material <NUM> up, onto and over the ramp <NUM>, as shown in <FIG>.

Once the roll of material <NUM> is placed on the ramp <NUM>, the ramp will facilitate movement of the roll of material <NUM> to the second dispensing position <NUM> as shown in <FIG>. The dispenser <NUM> also includes a stub roll support base <NUM> and an upper stub roll support member <NUM> configured to engage and secure the roll of material <NUM> in the second dispensing position <NUM>. In certain embodiments, the edges of the ramp <NUM> function to prevent the roll of material <NUM> in a second dispensing position <NUM> from being pulled off the stub roll supports, including the stub roll support base <NUM> and the upper stub roll support member <NUM>.

As shown in <FIG>, the roll of material <NUM> generally has a diameter as shown by "D". For certain rolls of material known as large rolls or jumbo rolls, the initial diameter "D" of a full, unused from may be from about <NUM> to about <NUM>, such as from about <NUM> to about <NUM>. Once the diameter "D" of the roll of material <NUM> reaches a transfer diameter size, the roll transfer apparatus facilitates movement of the roll of material <NUM> from the first dispensing position <NUM> to the second dispensing position <NUM>. In certain embodiments, the transfer diameter may range from about <NUM> to about <NUM>, such as from about <NUM> to about <NUM>.

Referring now to <FIG>, the dispenser <NUM> may also include a rearward section <NUM> that defines an opening or a space sufficient to allow an empty core <NUM> from the roll of material <NUM> to pass by and be stored in the rearward section <NUM> until such time as the service personnel arrives to service the dispenser <NUM>. For example, the roll of material <NUM>, can include a sheet of material or sheets of material that are wound around a core, such as paperboard core. The dispenser <NUM>, is capable of automatically moving the roll of material <NUM> from the first dispensing position <NUM> to the second dispensing position <NUM>. It is contemplated, that restroom personnel can insert a fresh or new roll of material <NUM> in a first dispensing position <NUM> without removing the remaining roll of material located in the second dispensing position <NUM>. Once the roll of material is the second dispensing position <NUM> is depleted it can remain in the second dispensing position while material is then removable from the fresh roll of material <NUM> in the first dispensing position <NUM>. However, once the roll of material in the first dispensing position <NUM> reaches the particular transfer diameter, the roll transfer apparatus <NUM> will move the material roll into the second dispensing position <NUM> and the fully used core currently occupying the second dispensing position will be pushed into the rearward section <NUM> so that the roll of material can be utilized in the second dispensing position <NUM>. In said embodiments, the remaining core of a completely used roll of material will not impede another roll of material from moving from the first dispensing position <NUM> to the second dispensing position <NUM>.

One or more fasteners can be used to secure the rear housing <NUM> to the mounting surface, such as the interior wall of a restroom stall. Indeed, the backplate <NUM> of the rear housing <NUM> can include one or more openings configured to receive a fastener for securing the rear housing <NUM> to the mounting surface. The fastener can include any hardware device that mechanically joins affixes two or more objects together. The fastener(s) can be used to join the rear housing <NUM> to the mounting surface to a bracket located on the mounting surface. The fastener(s) can include those that are able to create non-permanent joints, that is, the joint can be removed or dismantled without damaging the joined components. Thus, the fastener(s) selected can be used to removably join the rear housing <NUM> to the mounting surface. Any suitable fastener can be used. Suitable fasteners include, but are not limited to, anchors, bolts, nails, nuts, pins, clips rivets, rods, screws, clamps, washers, and combinations thereof. In one embodiment, the fastener(s) includes a screw.

The present dispenser <NUM> can be used to hold any material stored on or dispensed from a roll, including but not limited to toilet paper, paper towels, hand towels, plastic materials etc. In certain embodiments, the roll of material includes a jumbo roll of toilet paper or toilet tissue. While in many embodiments, the roll of material will include a core, it is contemplated that the present disclosure can also be used with coreless products or small core products.

Also provided is a method for replacing a roll of material or for inserting a roll of material into a dispenser including accessing the housing interior, placing a roll of material in the first dispensing position, removing a partially used roll of material (i.e. stub roll) or the core from a fully used roll of material from the second position, and securing the openable cover to the rear housing. The method further includes placing the roll of material on the transfer arm roller and moving transfer arm such that the hook of the transfer latch engages the notch of the transfer disk.
