Technical Field
The present application related to a pack, preferably a resealable pack, for wipes. More preferably
said wipes are disposable. The pack comprises an opening specifically located so as to permit
easy access to and removal of the wipes from the pack. The pack is also specifically designed so
as to be at least 1.16 times larger than the wipe in either the x- or y-dimension.
Background to the Invention
Wipes have recently become the medium of choice in the surface cleaning field. Such wipes are
generally packaged in reclosable, generally rigid, generally plastic boxes. However such boxes are
quite large and thus take up more surface area on the work surface, for example the kitchen work
surface, than is preferred. Moreover the boxes although reclosable are not resealable and thus
allow the entry and/or exit of moisture. And finally such boxes incur greater cost to the
manufacturer and thus also to the consumer.
Flexible packs are designed to be used as such or designed to be placed inside the reclosable box.
The flexible pack is easy to produce by flow wrap technology and uses less raw materials than the
box and which reduces both cost to the manufacturer, consumer and the environment. The
opening of a flexible pack, such as those described above are usually provided by means of a
perforated area in one face of the package that the consumer would open before use. Such flexible
packages can be made with resealable openings, wherein the removable opening area of the
package is covered with an adhesive film extending beyond the size of the opening, such that, the
adhesive film can then be used as a resealing adhesive label.
The packages of the present invention are specifically designed for use in packaging and
dispensing of dry or substantially dry wipes. The dry wipes are stiffer than the average wet wipe
and thus are less easily manipulated. When such packs are used with wet wipes, the opening is
made as small as possible and the consumer must pinch the wipe in order to grasp and remove it
from the pack. The wipe folds as necessary from the point of being pinched in order to be
removed from the pack through the opening. However the wipes for which the present pack has
been designed are less flexible than standard wet wipes. They can not be pinch gripped and do not
fold and thus are difficult to remove from the pack.
The Applicants have thus designed the present pack to be able to accommodate such less flexible
wipes. The packs of the present invention are oversized as compared to the wipes containing
therein. The extra size of the pack versus the wipe permits manoeuvrability of the wipe within the
pack. Hence the wipe can be manoeuvered within the pack so as to encourage an edge of the wipe
to be available at the opening. The opening of the pack is located in the body portion such that an
edge of the wipe contained therein can be easily accessed through the opening.
Summary of the Invention
According to the present invention there is provided a pack for dispensing at least substantially
dry wipes 7, having a body portion 1 defining an article-receiving cavity and being provided with
an opening 3, characterized in that said pack comprises at least one substantially dry wipe 7, said
body portion 1 is at least 1.16 times longer than the wipe in either the x or y dimension.
According to the present invention there is also provided a pack for dispensing at least
substantially dry wipes, having a body portion 1 composed of two horizontal and two longitudinal
sides, defining an article-receiving cavity and being provided with an opening 3, characterized in
that said pack comprises at least a substantially dry wipe 7 having at least two longitudinal and
two horizontal edges, and said body portion 1 being at least 1.16 times longer than at least either
the horizontal or longitudinal edge of the wipe contained therein.
Detailed Description of the Invention
Figure 1 is a perspective view of the pack of the present invention also showing a stack of 3 wipes
contained within the pack.
Figure 2 is a perspective view of the wipe contained within the pack of the present invention.
The packs of the present invention are generally formed from plastic materials for example a
polyethylene film, polypropylene film or a laminate consisting of for example polyethylene or
polypropylene layers. The body portion 1 is preferably formed of a single sheet of plastic material
sealed at its ends by end seams 2 and a longitudinal seam on the face of the body portion that does
not contain the opening (the reverse face, not shown in Figure 1). Preferably the pack is
substantially the same shape as the wipes contained therein. More preferably the packs are a
rectangular shape. An opening 3, preferably an elongated opening 3 is defined on the body portion
1. The opening 3 may be placed in the middle of one of the faces of the body portion 1 or may be
located over two faces of the pack i.e. over an edge of the pack. The opening 3 is preferably of
generally rectangular shape, preferably with rounded edges 4 so as to avoid forming sharp corners
which might be unhelpful as regards removal of the wipes from the pack or cause injury to the
user. The opening 3 is located at a point on the body portion 1 such that an edge of the wipe 7 can
be accessed through the opening 3. In said embodiment the body portion 1 comprises two shorter
horizontal sides and two longer longitudinal sides. The opening 3, preferably being of similar
shape to the body portion 1, is preferably located on the body portion 3 parallel to either the
horizontal or longitudinal sides. In said embodiment the opening 3 therefore exposes either the
longitudinal or horizontal edge of the wipe 7 contained therein.
The opening 3 is covered by a sealing member 5 which is resealably adhered to the body portion 1
around the perimeter of the opening 3 by means of an adhesive, for example an acrylic-based or
rubber-based adhesive. Sealing is provided over the whole of the area where the sealing member 5
overlies the body portion 1, except for a tab 6 at one end of the sealing member. This tab 6
provides a location where the user can grasp the sealing member 5. It is necessary for even a small
opening 3 to provide a comparatively large sealing member 5, since the latter must extend beyond
the former around the perimeter of the opening 3 if it is to provide the requisite seal. The material
of the sealing member 5 i.e. the substrate to which the adhesive is applied, may for example, be a
polypropylene film, or a laminate of paper and polypropylene, paper and polyethylene or
polyethylene and polypropylene. Where a two layer laminate is used which includes paper, the
adhesive is advantageously applied to the paper.
When using the pack the user grasps the tab 6 and pulls the sealing member 5 away from the body
portion 1 to as to expose the opening 3. A wipe 7 is removed from the pack and the sealing
member 5 is replaced over the opening 3, resealing the pack.
The body portion 1 can be described in terms of x-, y- and z-dimensions. The z-dimension is
defined as being the dimension portrayed by the stack of wipes 7 contained within the said body
portion 1. The x- and y-dimensions are thus the dimensions portrayed by the length and width of
the wipe. The body portion 1 is at least 1.16 times longer than the wipe 7 in either the x or y
dimension. Clearly the body portion 1 is also more than 1.16 times larger than the wipe 7 in the z
-dimension so as to accommodate a stack of wipes. Alternatively the body portion 1 may also be
described as being at least 1.16 times longer than at least either the horizontal or longitudinal side
of the wipe 7 contained therein. The pack therefore gives the impression of being outsized as
compared to the wipe itself, being either overly wide or overly long or both.
The pack of the present invention comprises at least one, at least substantially dry wipe 7. More
preferably the pack comprises a stack of said wipes. The stack may comprise from 2-3 wipes to
for example 20 or 30 wipes. The wipe is preferably composed of several layers of substrate. Such
substrates may be selected from preferably nonwoven materials composed of natural or synthetic
fibres. Natural fibres include all those which are naturally available without being modified,
regenerated or produced by man and are generated from plants, animals, insects or by-products of
plants, animals and insects. Preferred examples of natural fibres include keratin fibres and
cellulosic fibres, including wood pulp, cotton, hemp, jute, fax and combinations thereof. Natural
material nonwovens useful in the present invention may be obtained from a wide variety of
commercial sources. Nonlimiting examples of suitable commercially available paper useful herein
include Airtex®, an embossed airlaid cellulosic having a base weight of about 71 gsm, available
from James River, Green Bay, WI; and Walkisoft®, an embossed airlaid cellulosic having a base
weight of about 75 gsm, available from Walkisoft U.S.A., Mount Holly, NC.
As used herein, "synthetic" means that the materials are obtained primarily from various man-made
materials or from natural materials that have been further altered. Nonlimiting examples of
synthetic materials useful in the present invention include those selected from the group
consisting of acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide
fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers and combinations
thereof. Examples of suitable synthetic materials include acrylics such as acrilan, creslan, and the
acrylonitrile-based fiber, orlon; cellulose ester fibers such as cellulose acetate, arnel, and acele;
polyamides such as nylons (e.g., nylon 6, nylon 66, nylon 610, and the like); polyesters such as
fortrel, kodel, and the polyethylene terephthalate fiber, polybutylene terephalate fiber, dacron;
polyolefins such as polypropylene, polyethylene; polyvinyl acetate fibers and combinations
thereof. These and other suitable fibers and the nonwovens prepared therefrom are generally
described in Riedel, "Nonwoven Bonding Methods and Materials," Nonwoven World (1987); The
Encyclopedia Americana, vol. 11, pp. 147-153, and vol. 26, pp. 566-581 (1984); U. S. Patent No.
4,891,227, to Thaman et al., issued January 2, 1990; and U. S. Patent No. 4,891,228, each of
which is incorporated by reference herein in its entirety.
In a preferred embodiment the wipe also comprises an abrasive net of fibres, otherwise known as
a scrim. By the term 'net' it is meant a structure made directly from melts or fibres which are at
least 0.2mm long and are held together by systems other than hydrogen bonding. The fibres may
be selected from metal, natural or synthetic wires, filaments or stands or mixtures thereof.
Preferred fibres are selected from those of synthetic organic origin, more preferably from
polymeric synthetic organic origin and thermoplastic polymers. The fibres are preferably selected
from polyamide, polyethylene, polypropylene fibres and mixtures thereof.
The wipe 7 preferably comprises a detergent composition. More preferably said detergent
composition is in the form of a paste and applied to the wipe in strips 8. The layers of substrate of
the wipe 7 are preferably bonded 9 to one another. Most preferably the layers of substrate are spot
heat bonded to one another. In a particularly preferred embodiment the pattern of bonding and
stripes of detergent paste encourages the wipe to be bent or folded along particular fold lines. The
bonding pattern and the stripes of detergent paste thus both aid the removal of the more rigid wipe
from the pack when the size of the opening is less than the length of the wipe accessing through
the opening.
