The disclosure generally relates to a tissue dispenser, a method for dispensing tissue and, a tissue dispenser insert. The disclosure provides for conservation of tissue, such as toilet tissue, by requiring that a first roll of tissue is exhausted before a second roll of tissue can be accessed.
Numerous styles of tissue dispensers are available. One style of tissue dispenser found in many commercial establishments is a tissue dispenser where two rolls of tissue are located side by side. For that style of tissue dispenser, it is often the problem that a user will begin the second roll of tissue before the first roll of tissue is exhausted. The custodian who services the tissue dispenser often ends up replacing both partially used rolls with new rolls of tissue thereby resulting in waste. Examples of two roll dispensers are disclosed in U.S. Pat. Nos. 6,439,502; 6,202,956; 5,813,624; and 3,381,909. A dispenser that helps reduce waste by requiring depletion or substantial depletion of a first roll before access to a second roll is made available is disclosed in U.S. Pat. No. 7,083,138.
One type of tissue dispenser includes a metal housing typical of the dispenser shown in
Toilet tissue rolls and other paper roll products, such as paper towel rolls, typically comprise a paper web material that is wound around a central core. The core helps to support the paper web material and define the shape of the roll, as well as define a central opening for interaction with a support structure, such as a mandrel, on a suitable dispensing apparatus.
In many paper roll products, the core is a one piece structure that extends the entire width of the roll product. However, in some known paper roll products, the core is formed by core sections that are spaced apart from each other to form a gap between the core sections so that the total length of the core sections is less than the width of the web material wound onto the core sections. These reduced core paper roll products having spaced core sections separated by a gap help to reduce the amount of core stock material that is used in paper roll products. Examples of reduced core paper roll products are disclosed in U.S. Pat. Nos. 7,107,888; 6,648,267; and 6,491,251.
Exemplary tissue dispensers that encourage depletion of a roll of tissue before another roll of tissue is available are disclosed, for example, by U.S. Pat. Nos. 7,014,140; 6,648,267; and 6,491,251. There is a continuing need for tissue dispensers that encourage depletion of a first tissue roll before consuming a second tissue roll.
A tissue dispenser is provided according to the present invention. The tissue dispenser includes a housing for storing and dispensing multiple rolls of tissue, and a mandrel set constructed to move within the housing. The housing includes a first side wall and a cover constructed to provide an opening through which tissue can be dispensed, and a track extending along a portion of the first side wall. The mandrel set includes a first mandrel constructed to hold a first roll of tissue, a second mandrel constructed to hold a second roll of tissue, and an arm extending from the first mandrel to the second mandrel. Extending from the arm are a first pin and a second pin wherein the first pin and the second pin are constructed to engage and travel along the track. The tissue dispenser is constructed so that a roll of tissue on the first mandrel can be dispensed from the opening while the roll of tissue on the second mandrel is held in reserve, and once the roll of tissue on the first mandrel is depleted, the mandrel set can move along the track so that the roll of tissue on the second mandrel can be dispensed from the opening. The tissue dispenser can be constructed so that the mandrel set is unable to advance to a position where tissue can be dispensed from the second mandrel until the roll of tissue on the first mandrel is depleted.
A method for dispensing tissue from a tissue dispenser is provided according to the present invention. The method includes steps of: dispensing tissue through an opening in a tissue dispenser housing from a lower mandrel of a mandrel set in a first dispensing configuration until the tissue is depleted, the mandrel set having an upper mandrel and the lower mandrel; and displacing the lower mandrel so that the mandrel set moves into a second dispensing configuration for dispensing tissue from the upper mandrel through the opening, wherein the mandrel set has an arm separating the lower mandrel and the upper mandrel, and a pin arrangement so that the mandrel set moves along a track.
A tissue dispenser insert constructed for retrofitting a tissue dispenser housing is provided according to the present invention. The tissue dispenser insert includes: a track having a track inlet, a track outlet, and a track length extending from the track inlet to the track outlet, the track length constructed to provide a first dispensing location and a second dispensing location; and a mandrel set comprising a first mandrel constructed to hold a first roll of tissue, a second mandrel constructed to hold a second roll of tissue, and an arm extending from the first mandrel to the second mandrel, the arm including a first pin and a second pin wherein the first pin and the second pin are constructed to engage and travel through the track from the track inlet to the track outlet.
A tissue dispenser is provided that includes a tissue dispenser housing and a mandrel set. Now referring to
The reference to the roll of tissue being depleted can mean that the roll is completely depleted or substantially depleted. The terms “completely depleted” and “substantially depleted” as used herein mean all or a sufficient amount of tissue has been removed from a roll at the dispensing position to allow movement of the second roll of tissue into position so that it can be accessed through the opening or slot 22. For the sake of convenience, the term “depleted” will hereinafter be used. It should be understood that the term “depleted” encompasses both complete depletion of tissue as well as depletion to an extent that permits access of the roll of tissue held in reserve.
The tissue dispenser housing 20 includes a first side wall 26, a second side wall 28, a bottom side wall 30, a top side wall 32, and a back side wall 34. Provided on the first side wall 26 is a slot arrangement 40. Although shown on first side wall 26, the slot arrangement 40 can be provided on the second side wall 28. In addition, the slot arrangement 40 can be provided on both the first side wall 26 and the second side wall 28. The slot arrangement 40 can be constructed as part of the first side wall 26 or the second side wall 28 or both, or the slot arrangement 40 can be provided as an insert that can be attached or affixed to the first side wall 26 or the second side wall 28 or both. When provided as an insert, the slot arrangement 40 can be provided as a retrofit alternative to an existing tissue roll dispenser housing such as the disperser shown in
The cover 24 is shown extending over at least the first side wall 26, the second side wall 28, and the top side wall 32. It should be appreciated that alternative arrangements can be provided, as desired. The cover 24 is provided to create the opening or slot 24 through which tissue can be accessed. As a result, the cover 22 can be provided so that it covers a sufficient extent to create the opening or slot 22. Furthermore, it should be understood that certain walls of the tissue dispenser housing 20 may not be necessary depending on the design of the cover 24. In addition, certain walls can be avoided if they are not needed such as, for example, the back side wall 34 and/or the bottom side wall 30.
Now referring to
The mandrel set 44 includes a pin arrangement 60 for engaging the slot arrangement 40. The pin arrangement 60 includes a first pin 62 and a second pin 64. The first pin 62 and the second pin 64 are constructed so that they slide within the track 42 in the slot arrangement 40. The first pin 62 and the second pin 64 each include a head 68 extending from a shaft 65 which attaches to the arm 50. It should be understood that the shaft 65 can be characterized as attaching the first pin 62 and the second pin 64 to the first mandrel 48 and the second mandrel 49, respectively. In addition, the first pin 62 and the second pin 64 can be provided on the arm 50 at locations other than locations corresponding to the first mandrel 48 and the second mandrel 49.
The track 42 extends from a track opening 70 to a track exit 72. For the track 42 shown in
The first mandrel 48 and the second mandrel 49 each include a first end 80 and a second end 82. The first end 80 is shown attached to the arm 50, and the second end 82 is shown as free floating. When provided as free floating, the second end 82 is not supported by any part of the tissue dispenser 20. The first mandrel 48 and the second mandrel 49 both include a recessed region 84. For the design shown in
Although reduced core tissue rolls are preferably used with the mandrel set 44, alternatives can be provided. For example, the tissue core can be fully removed from the mandrel in order to expose the recessed region 84. The core can be provided as a “bursting” type core that is sometimes used in industrial and institutional applications. Bursting cores are intended to come apart after the tissue has been removed, leaving the mandrel bare. Alternatively, the tissue roll can have a core that is manually removed once the tissue is depleted. In the case of reduced core tissue rolls, the size of the core corresponding to the recessed region 84 should be less than or equal to the size of the recessed region 84 so that the core can shift. Alternatively, the size of the gap should correspond to at least the size of the stop 86 so that the recessed region 84 is sufficiently exposed to allow the mandrel to move past the stop 86. It should be appreciated that variations of the mandrel can be used. For example, one could utilize a mandrel design as shown, for example, in U.S. Pat. No. 7,014,140, the disclosure of which is incorporated herein by reference, where the mandrel is provided having differential diameter so that the core on the smaller diameter portion can be shifted to create a gap so that the mandrel can bypass a stop.
The mandrel set 44 includes a flange or tab 51 extending from the arm 50 about midway between the first mandrel and the second mandrel 49. The flange or tab 51 can be provided having various shapes or sizes, but is generally provided to separate the rolls of tissue provided on the first mandrel 48 and the second mandrel 49. The mandrel set 44 can be provided without the tab 51, if desired. The arm 50 additionally includes a second region 53 that generally corresponds to the recessed region 84 on the first mandrel 48 and the second mandrel 49 to allow the arm 50 to pass by the stop 86. Of course, the stop 86 can be provided separate and spaced apart from the slot arrangement 40 in which case the provision of a recessed region 53 can be avoided.
In
The tissue dispenser is provided so that it can be conveniently serviced by a custodian. The custodian opens the tissue dispenser housing 20 by removing or rotating the cover 24. The custodian then lifts the mandrel set 44 slightly so that the shaft and head 68 engage the track exit 72, and pulls the first mandrel 48 out of the slot arrangement 40. The slot arrangement 40 can be designed so that it is unnecessary to lift the mandrel set 44 slightly so that the head 68 engages the track exit 72. That is, in one variation, the custodian can simply pull the first mandrel 48 so that it engages the track exit. It is expected, however, that by providing a lower extension 73 below the track exit 72, tampering with the dispenser can be discouraged. Furthermore, the mandrel set 44 will likely remain in a more secure position in the second dispensing configuration 92. In
Once the mandrel set 44 is returned to the first dispensing configuration 90, the custodian can replace the cover 24. The process can be repeated thereby requiring complete dispensing of a roll of tissue before a new roll is available. If desired, the custodian can back the entire mandrel set out of the slot arrangement 40 in order to replace both rolls even if the second roll has not been fully depleted.
The movement of a mandrel through the track 42 can be characterized as a generally downward movement through the first region 100, a generally rearward movement through the second region 102, and a generally downward movement through the third region 103. The first region 100 can be characterized as the region extending from the entry 70 to the bend 105 where the first mandrel 48 is located in the first dispensing configuration 90. The second region 102 can be referred to as the region extending from the bend 105 to the stop 86. The third region 103 can be characterized as the region extending from the stop 86 to the lower end 106 which is where the first mandrel 48 is located when provided in the second dispensing configuration 92. The region first 100 can include a generally rearward movement at the entry 70, and the movement at the third region 103 can be characterized as a forward movement at the exit 72. In addition, the movement within the first region 100 can be characterized as generally downward and forward. The movement in the second region 102 can be characterized as generally rearward and upward. In addition, the movement in third region 103 can be characterized as generally downward, and then upward and forward through the exit 72.
