Description

BACKGROUND

Disposable sheet style dispensers are well known in the art for dispensing individual folded sheet products such as facial tissues, hand wipes, or the like. In general, disposable sheet dispensers typically include a container and a stack or clip of prefolded, interfolded sheets disposed within the container. The sheets may be C-folded or V-folded so that once the top sheet in the clip is withdrawn, the underlying sheet is individually presented for subsequent use.

In use, the sheets are dispensed through a fairly large oval or diamond shaped opening centrally located in the top panel of the carton. To access the sheets, the user reaches into the carton through the opening to access the top sheet and then pulls the top sheet through the opening.

One of the most common problems found in disposable sheet dispensers concerns the issue of “fall back”. This involves a situation where the leading edge of the sheet drops down through the dispensing slot. The user must then reach into the carton and grasp the sheet, pulling it out of the carton for use. Sometimes, this results in several sheets being removed from the carton instead of just one. Further, the opening in the top of the carton may not be large enough to accommodate a user's hand, resulting in damage to the top panel of the carton.

Damage to the opening slot may promote more fall back since it weakens the support the leading edge may have gotten from the slot structure.

There are many ways in which fall back may occur. Three common ways are mentioned here and they all involve situations where the box is approximately half empty or less. First, the stack inside the box cannot support itself straight up, so it starts to fold over. As it folds over, it pulls the leading edge of the tissue down below the dispensing slot. Second, as in the first example, the stack does not support itself and has bent over, pulling the leading edge closer to the dispensing slot. In this case, if the box gets moved or bumped which causes either movement in the stack which pulls the leading edge all the way through, or the leading edge just falls down through the slot. The third example is that the sheets in the box have somehow worked themselves apart a bit, so that when the leading edge is pulled the overlap comes apart and fails to bring up the leading edge of the next sheet.

The situation of “fall back” is defined as a quality defect, and is considered to be a major inconvenience to the user and has resulted in user complaints. A need in the art exists for a disposable sheet dispenser carton that significantly reduces “fall back” and improves the performance of past disposable sheet dispensers.

DETAILED DESCRIPTION

Reference will now be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, and not meant as a limitation of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a third embodiment. It is intended that the present invention include these and other modifications and variations. [0028]
Referring now to the drawings, FIG. 3 shows a [0029] sheet dispenser carton 10 having a support member 22. The support member 22 is located within the dispensing carton 10. The support member 22 rests on the bottom wall 14 of the dispensing carton 10. A stack of interfolded sheets 28 is positioned inside dispensing carton 10, and rests on top of the support member 22.
One embodiment of a [0030] support member 22 in accordance with the present invention is shown in FIG. 1A. Here, the support member 22 consists of a folded sheet of relatively stiff or rigid cardboard. However, it is to be understood that the support member 22 can be made of any type of material and is not limited to only cardboard. The support member 22 is folded into generally four sections. Two of these sections are the legs 34 of the support member 22. The legs 34 are on either side of the sides 26 of support member 22. An edge 24 of the support member 22 is formed by the meeting of both sides 26 of the support member 22. In accordance with one embodiment of the present invention, the sides 26 and legs 34 of the support member 22 when viewed on end have a substantially inverted T-shape.
As shown in FIG. 2, the [0031] support member 22 is placed inside of the dispensing carton 10. The dispensing carton 10 consists of four side walls 16 that are contiguous with one another. Further, the dispensing carton 10 also has a top wall 18 contiguous with the four side walls 16. A bottom wall 14 is present which is likewise contiguous with the four side walls 16. FIG. 2 shows that the support member 22 can be inserted into the dispensing carton 10 through an opening in one of the side walls 16. However, it is to be understood that the present invention is not limited to insertion of the support member 22 into the dispensing carton 10 through a side wall 16. For instance, the support member 22 can be inserted through either the top wall 18, the bottom wall 14, or formed integrally with dispensing carton 10. Additionally, the dispensing carton 10 can be formed around a preexisting support member 22, and the invention is not limited to a particular way of inserting support member 22 into the dispensing carton 10.
The stack of [0032] interfolded sheets 28 consists of a plurality of individual interfolded sheets 36. The interfolded sheets 36 may also be referred to as interfolded wipes. The stack of interfolded sheets 28 is placed on top of the support member 22. The stack of interfolded sheets 28 is folded in such a way that a central pocket 29 is formed. The sides 26 of the support member 22 are positioned inside of the pocket 29. The Edge 24 may have a height so as to engage the stack of interfolded sheets 28 in one embodiment.
FIG. 3 shows an assembled view of the [0033] carton 10, stack of interfolded sheets 28, and support member 22. An aperture 20 is present in the top wall 18 of the dispensing carton 10. Sheets 36 may be dispensed through the aperture 20. Such a dispensing technique is well known in the art, along with the method of interfolding the stack of interfolded sheets 28 such that the interfolded sheets 36 are configured to allow for the single dispensing of a sheet 36 and subsequent replacing of sheet 36 as one is dispensed.
The presence of [0034] support member 22 prevents the stack of interfolded sheets 28 from falling towards the bottom wall 14 of the dispensing carton 10 as the sheets 36 are removed. In effect, the support member 22 urges the stack of interfolded sheets 28 towards the top wall 18 of the dispensing carton 10.
FIG. 4 shows a stack of [0035] interfolded sheets 28 in phantom lines that are not supported by a support member 22. FIG. 4 also shows a stack of interfolded sheets 28 in solid lines that are supported by a support member 22. As can be seen in FIG. 4, the stack 28 that is supported by support member 22 is held closer to the top wall 18 than the stack 28 that is not supported by support member 22 which falls towards the bottom wall 14. Keeping the stack of interfolded sheets 28 towards the top wall 18, especially when few interfolded sheets 36 remain, helps prevent the problem of “fall back”. It has been found that when fewer interfolded sheets 36 are present in the stack of interfolded sheets 28, the center height of the stack of interfolded sheets 28 falls towards the bottom wall 14. Inclusion of a support member 22 helps to maintain the original center height of the stack of interfolded sheets 28 and consequently minimizes fall back of the interfolded sheets 36.
FIG. 1B shows an alternative embodiment of the invention, wherein the [0036] support member 22 has an adhesive 30 applied to the sides 26. Although FIG. 1B only shows the adhesive 30 being applied to one side 26, it is to be understood that the adhesive 30 may be applied to both sides 26. Now referring also to FIG. 2, when the stack of interfolded sheets 28 is placed upon the support member 22, the end sheet 32 of the interfolded sheets 36 contacts the adhesive 30 and is retained thereon. This retention helps to keep the stack of interfolded sheets 28 in place during the removal of sheets 36. The use of the adhesive 30 has been found advantageous especially when few interfolded sheets 36 are left in the stack of interfolded sheets 28. It is to be understood that the adhesive 30 may be of various forms in different embodiments of the present invention. For instance, the adhesive 30 may be in the form of an adhesive strip or pattern of glue. Further, the adhesion force on the end sheet 32 as shown in FIG. 4 may be strong or weak, allowing for the end sheet 32 to be dispensed as were the other sheets 36 or to be retained on the support member 22 and not dispensed.
Referring now to alternative embodiments shown in FIGS. 1A, 1B, and [0037] 2, the support member 22 can be an individual component that is inserted into the dispensing carton 10, or can be a component formed integrally with the dispensing carton 10. The edge 24 of the support member 22 can be in one embodiment a straight edge. However, the invention is not limited to the edge being a straight edge.
The [0038] sides 26 of the support member 22 are substantially vertical and approach being parallel to the side walls 16 of the dispensing carton 10. The legs 34 of the support member 22 are substantially parallel with the bottom wall 14 of the dispensing carton 10. By having this configuration, the support member 22 allows for the stack of interfolded sheets 28 to be draped over the sides 26 of the support member 22 and at the same time have the edges 13 of the interfolded sheets 36 be substantially perpendicular to the legs 34 of the support member 22.
However, in some embodiments of the present invention, the [0039] edges 13 may not be substantially perpendicular to the legs 34. As seen from the side, the legs 34 and sides 26 are substantially in the shape of an inverted T.
The dispensing [0040] carton 10 can be of any number of shapes and sizes, for instance the dispensing carton 10 may be in the shape of a cube or may have a top wall 18 and bottom wall 14 that are rectangular shaped.
Addition of the [0041] support member 22 also provides other advantages to the sheet dispenser carton. For instance, the support member 22 may be sized such that the legs 34 each contact opposite side walls 16 of the dispensing carton 10. Further, the sides 26 of the support member 22 can be equally spaced from these side walls 16. Centering of the stack of interfolded sheets 28 on the sides 26 of the support member 22 therefore allows for a precise positioning of the stack of interfolded sheets 28 within the dispensing carton 10. This allows for a more accurate dispensing of the sheets 36 through the aperture 20 because a more precise alignment is attained. Such a support member 22 will also provide for stability of the stack of interfolded sheets 28 within the dispensing carton 10 during shipment of the sheet dispenser carton. The support member 22 is also advantageous in that it helps to keep the stack of interfolded sheets 28 urged towards the top wall 18 even if the dispensing carton 10 is turned such that the side wall 16 is now the bottom wall.
The present invention includes an embodiment of the [0042] support member 22 that has sides 26 and edge 24, but does not have legs 34.
FIG. 5 shows another embodiment of the dispensing [0043] carton 10 in accordance with the present invention. The dispensing carton 10 is composed of a top wall 18 and a bottom wall 14. Side walls 16 are present in this embodiment. Some of the side walls 16 are formed by two pieces, while other side walls 16 are formed by one piece. The support member 22 is made of two separate pieces in this embodiment. One of the pieces of the support member 22 is connected to one of the side walls 16, and another piece of the support member 22 is connected to a different side wall 16.
Although the [0044] support member 22 is shown as two separate pieces in this embodiment, it is to be understood that the support member 22 may be one piece that is connected to one of the side walls 16. Additionally, two of the side walls 16 of the dispensing carton 10 are shown as being formed by two separate pieces. It is to be understood that the present invention includes an embodiment of the dispensing carton 10 where the side walls of the dispensing carton 10 are formed by one or more pieces, and the invention is not limited to any number of pieces in forming side walls 16.
[0045] Adhesive 30 is applied to the support member 22 in FIG. 5. Adhesive 30 may be applied to one of the pieces of the support member 22 or to both of the pieces of the support member 22. The support member 22 functions substantially as previously discussed. A stack of interfolded sheets 28 is located over the edge 24 of the support member 22, and substantially surrounds the support member 22. FIG. 6 shows the support member 22 located in the central pocket 29 of the stack of interfolded sheets 28. FIG. 6 shows how the side walls 16 are folded in order to position the support member 22 into the central pocket 29. It may be the case that a loading machine (not shown) that is used to assemble the dispensing carton 10 with a stack of interfolded sheets 28 will have to be equipped with a guide element (not shown) to help position one or both pieces of the support member 22 into the central pocket 29. It may be the case that both pieces of the support member 22 contact one another upon assembly, or it may be the case that a gap is left between the pieces of the support member 22 upon assembly. Both of these configurations are to be considered within the scope of the present invention.
A preferred embodiment of the present invention consists of a dispensing [0046] carton 10 that is generally cube shaped, that is therefore in the shape of a boutique box.
It should be understood that the invention includes various modifications and variations that can be made to the embodiments of the sheet dispenser carton with a support member described herein as come within the scope of the appended claims and their equivalents. [0047]
