Definitions

  • the present invention relates to the field of packages for storing sheets for cleaning implements, and, more particularly, to the field of packages for sheets which are used with a floor mop having attachment structures for retaining a sheet about a mop head.
  • Mops which utilize a sheet, such as a woven or non-woven sheet, for cleaning are known in the art. These mops can be used to clean floors and the like and typically comprise a mop head and a handle pivotally connected to the mop head by a universal joint.
  • Various structures have been used to secure the sheet to the mop head.
  • US patent no. 5,815,878 to Murakami et al. discloses a sweeping device having a sweeper head with a pair of clamping members while JP3022675 appears to disclose a mop having a plurality of serrated structures located on the mop head for receiving a sheet.
  • the sheets used with these types of mops are disposable and therefore replaced after each use, it is often desirable to bundle together and market multiple sheets as unit for a consumer. While such sheets have been bundled together in non-resealable flexible pouches having slit-like openings, often times these sheets can be deformed during storage or removal from or reinsertion to the pouch such that their cleaning performance is degraded and/or the portion of the sheet which attaches to the mop cannot engage the mop head as effectively as it would prior to deformation. Further, some cleaning sheets may have three-dimensional surfaces which aid in the collection and retention of particulates within the sheet but which can also be susceptible to deformation. Therefore, there exists a need to provide improved packages which can protect the shape and/or three-dimensionality of these sheets. Further, there exists a need to provide improved package and sheet combinations which can accommodate removal and reinsertion of sheets without substantial deformation.
  • a package for storing a plurality of sheets used with a mop having a mop head with a plurality of attachment structures for retaining a sheet about the mop head includes a container having a front wall, side walls, a rear wall, and a bottom wall, wherein the walls form a compartment.
  • a plurality of sheets having a deformable scrim are stored within the compartment, wherein the sheets are folded about at least one longitudinal axis of the sheets.
  • a lid is attached to one of the walls, wherein the lid closes an opening in the container through which the sheets can be removed.
  • the opening of the package has a length at least about 40% of the length of the sheets stored in the compartment and, more preferably, has a width at least about 50% of the width of the sheets stored in the compartment.

  • Fig. 2 is a perspective view of the floor mop of Fig. 1, wherein the mop has a sheet attached thereto;
  • Fig. 3 is a perspective view of a preferred sheet suitable for use with the floor mop of Fig. 1 ;
  • Fig. 4a is schematic plan view of the preferred sheet of Fig. 4a illustrating the basis weight differences of the sheet;
  • Fig. 4b is a photomicrograph of the preferred sheet of Fig. 3 showing a textured three-dimensional surface
  • Fig. 5 is a top view of the floor mop of Fig. 1;
  • Fig. 6 is a cross-sectional side view of the mop head of Fig. 5, taken along line 6-6 thereof;
  • Fig. 7 is a perspective view of a package made in accordance with the present invention, wherein the lid is in the raised position;
  • Fig. 8 is a perspective view of the sheet of Fig. 3, wherein the sheet is folded about the two longitudinal axes;
  • Fig. 9 is a perspective view of the sheet of Fig.3, wherein the sheet is folded about two longitudinal axes and a transverse axis.
  • the present invention is directed to packages for storing sheets which are adapted for use with a cleaning implement and, more preferably, to packages for storing sheets which are adapted for use with a floor mop.
  • a floor mop 20 is illustrated.
  • the mop 20 comprises a mop head 22 and a handle 24 pivotally connected to the mop head 22 by a universal joint 26. As shown in Fig.
  • the sheet 27 is attached to the mop head 22 by a plurality of attachment structures 34.
  • the mop head 22 includes an elastic member 28 which is disposed about the periphery of the mop head 22 and which both tensions the sheet 27 about the mop head 22 and provides a support surface for the sheet 27.
  • the elastic member 28 has a length L M and a width D M , wherein the length L M is preferably between about 20 cm and about 30 cm and the width W M is between about 8 cm and about 12 cm.
  • the phrases “cleaning head” and “mop head” are intended to refer to the structure which engages and retains the sheet 27.
  • the mop head 22, and universal joint 26 are preferably formed from ABS type-polymers (e.g., terpolymer from acrylonitrile), polypropylene or other plastic material by injection molding while attachment structures 34 are preferably formed from injection molded polyethylene and the elastic member 28 is preferably formed from polyurethane by molding.
  • the handle 24 can be formed from plastic, aluminum, or other structural materials.
  • the floor mop 20 and mop head 22 illustrated in the accompanying Figures are but one configuration which is suitable for use with the present invention.
  • the mop head 22 can be provided in other shapes and sizes and may be configured for other types of cleaning, such as cleaning walls, around corners, furniture and the like.

  • the sheets also preferably have a continuous high and discrete low basis weight regions 32 and 33, respectively, such as shown schematically in Fig. 4a, and/or a three- dimensional surface, such as shown in Fig. 4b, both features being more fully described in US patent application serial nos. 09/082,349 and 09/082,396. While the low basis weight regions are depicted as being of essentially the same size and of a single well defined shape, these regions may be of differing sizes to facilitate entrapment of particles of varying size and shape. The high and low basis weight regions and the three dimensionality of the surface of the sheet shown in Figs. 4a and 4b assists in receiving and trapping material, such as dust and dirt, in the sheet.
  • a continuous high and discrete low basis weight regions 32 and 33 respectively, such as shown schematically in Fig. 4a, and/or a three- dimensional surface, such as shown in Fig. 4b, both features being more fully described in US patent application serial nos. 09/082,349 and 09/
  • the sheets 27 can be made using either a woven or nonwoven process, or by forming operations using melted materials laid down on forms, especially in belts, and/or by forming operations involving mechanical actions/modifications carried out on films.
  • the structures are made by any number of methods (e.g., spunbonded, meltblown, resin bonded, air-through bonded, etc.), once the essential three dimensional and basis weight requirements are known.
  • the preferred structures are nonwoven, and especially those formed by hydroentanglement as is well known in the art, since they provide highly desirable open structures.
  • heat-bonded nonwoven structures which utilize continuous filaments bonded to a base sheet via heat-sealed lines.
  • Materials particularly suitable for forming the fibrous material 30 of sheet 27 include, for example, natural cellulosics as well as synthetics such as polyolefins (e.g., polyethylene and polypropylene), polyesters, polyamides, synthetic cellulosics (e.g., RAYON®), and blends thereof. Also useful are natural fibers, such as cotton or blends thereof and those derived from various cellulosic sources.
  • Preferred starting materials for making the hydroentangled fibrous sheets of the present invention are synthetic materials, which may be in the form of carded, spunbonded, meltblown, airlaid, or other structures. Particularly preferred are polyesters, especially carded polyester fibers.
  • the degree of hydrophobicity or hydrophilicity of the fibers is optimized depending upon the desired goal of the sheet, either in terms of type of soil to be removed, the type of additive that is provided, when an additive is present, biodegradability, availability, and combinations of such considerations. In general, the more biodegradable materials are hydrophilic, but the more effective materials tend to be hydrophobic.
  • the sheets 27 preferably have a width Ws and length Ls and, preferably, the width Ws is between about 18 cm and about 22 cm while the length Ls is between about 25 cm and about 35 cm for an elastic member having a width W M between about 8 cm and about 12 cm and a length L M between about 20 cm and about 30 cm. While the above-described sheets are preferred, it will be understood that other sheet materials, dimensions, and constructions may be equally suitable for use with the present invention.
  • the sheets 27 are attached to the mop head 22 by a plurality of attachment structures 34.
  • the attachment structures 34 are configured to receive and retain the sheet 27 about the mop head 22, as shown in Fig. 2, during use.

  • the attachment structures 34 also preferably comprise a plurality of pie-shaped sections 42 having apexes 44.
  • the pie-shaped sections 42 are defined along two sides thereof by slits 48 which extend through the flexible material which forms the attachment structures 34. This arrangement permits the pie- shaped sections 42 to individually deflect relative to each other.
  • the slits through the flexible material of the attachment structure 34 allow the pie-shaped sections 42 and the base triangle 36 to deflect under finger pressure so that a portion of the sheet 27 can be pushed through the top surface of the attachment structures 34 and into a cavity 49 (Fig. 6) formed within the attachment structures 34.
  • the apexes 44 of the pie-shaped sections 42 and the apex 40 of the base triangle 36 can pierce and engage the sheet 27 such that the sheet is retained about the mop head 22 during use.
  • the above-described dry mop is preferred, it will be understood that other arrangements, materials and configurations would be equally suitable for use with the present invention.
  • other joints can be used in place of the universal joint 26 to provide relative movement between the handle 24 and the mop head 22 and the mop head 22 can be provided in the form of other shapes and configurations (e.g., with a textured bottom surface, curvilinear side walls, etc.).
  • the attachment structures 34 are preferred, it will be appreciated that the dry mop 20 can incorporate other configurations for the attachment structures 34.

  • the scrim 29 provides a support structure for the fibrous material 30.
  • semi-permanent and/or permanent deformations e.g., "dog ears” and other irregularlities
  • Such deformations can degrade not only the cleaning performance of the sheets 27 but also, if severe, affect engagement between the sheet 27 and the attachment structures 34.
  • a preferred package 50 for storing the sheets 27 which can prevent undesirable deformations is illustrated in Fig. 7.
  • the package 50 includes a lid 52 hingedly attached to a rear wall 54, a top wall 55, a front wall 56 disposed opposite the rear wall 54, a bottom wall 58, and opposing side walls 60 and 62.
  • the lid 52 which is preferably recloseable, and the walls form a compartment 64 for storing the sheets 27. More preferably, the compartment 64 is sized to store between about 5 and about 100 sheets, and, more preferably, between about 8 and about 64 sheets. Perforations or, more preferably, scoring define the edges of the lid 52 as well as an opening 68 through which the sheets 27 can be removed.
  • the scoring allow a user of the package 50 to easily separate the lid 52 from the top wall 55 to expose the compartment 64.
  • the package 50 is preferably formed from paperboard, cardboard, corrugated cardboard or other suitable material and is substantially rigid. As used herein, the phrase "substantially rigid" is intended to refer to a package 50 whose height H 0 (Fig. 7), when subjected to a 7.5 lb load distributed across the top of the package 50, is at least about ninety percent and, more preferably, at least about ninety-five of the height Ho of the package 50 without an applied load.
  • package 50 has been illustrated herein as generally rectangular in plan view and the lid 52 has been described herein as hingedly attached to the rear wall 54, it will be appreciated that the walls and lid of package 50 can be provided in other shapes and configurations without departing from the scope of the present invention.
  • the lid 52 might be provided as detachable from the package 50.
  • the sheets 27 which are stored in the compartment 64 are preferably folded about longitudinal and transverse axes of the sheet. More particularly, the sheet 27 is preferably folded about first and second longitudinal axes 70 and 72 (Fig. 3), wherein the width W B between the longitudinal axes is about equal to the width W M of the elastic member 28. In other words, portions 74 of a sheet 27 which engage the attachment structures 34 of the mop 20 are folded over on top of the base portion 76 (i.e., the portion defined by the width W B as shown in Fig. 3) of the sheets 27, as shown in Figs. 8 and 9.
  • the sheets 27 preferably comprise a deformable scrim 29
  • the portions 74 which engage the attachment structures 34 are protected from deformation by both the rigid package 50 and the fact that these portions are disposed interiorly of the walls of the package 50.
  • the folding pattern for the sheets 27 provides a set of sheets whose three-dimensional surfaces are less likely to suffer deformation because of an "air cushion" which is established between the folded sheet layers.
  • the opening 68 of the package 50 is also preferably sized to prevent deformation of the sheets 27 and has a length L 0 and a width Wo (Fig. 7) which are at least about 40% and 50%, respectively, of the folded length L F and folded width W F (Fig. 9) of the sheets 27. More preferably, the length Lo is between about 65% and about 85% of the folded length L F and the width Wo is between about 80% and about 100% of the folded width W F . Most preferably, the opening 68 has a length Lo between about 10 cm and about 13 cm and a width Wo between about 11cm and about 13 cm for a folded sheet 27 having a folded length L F between about 13 cm and about 16 cm and a folded width W F of between about 9 cm and about 12 cm.
  • An opening 68 sized accordingly can allow a sheet 27 to be removed from and reinserted to the package 50 without damage.
  • the sheets 27 are also preferably folded about the transverse axis 78 (Figs. 3 and 8) which is located at about the midpoint of the length Ls. Folding the sheet 27 about the transverse axis 78 permits the size of the opening 68 to still be maximized relative to the size of the folded sheet for removal from the package 50 while providing an overall package size which is convenient for storage.
