FIG. 9 illustrates a flow chart of a method of making a powder dispensing pad. - The present invention makes use of the discovery of a powder dispensing pad. The powder dispensing pad includes a bottom barrier layer, and a top barrier layer. The top and bottom barrier layers are sealed together, to maintain the powder between them before being dispensed. Inside the powder dispensing pad is a storage layer, with the powder present within the storage layer, or the powder being present between the storage layer and the bottom barrier layer. A metering layer having pores is present between the storage layer and the top barrier layer, to evenly meter out the powder to the top barrier layer. The top barrier layer includes holes, to dispense the powder. Other optional layers may be present, including a sealing layer having an adhesive layer, for covering the holes in the top barrier layer prior to use. The powder dispensing pad may also be in a container, such as a plastic bag, or a container for holding a plurality of the powder dispensing pads.
-
FIG. 1 illustrates a powder dispensing pad, 100, within a container, 190, for example a sealed clear plastic bag. The powder dispensing pad includes a top barrier layer, 140, and a bottom barrier layer, 110, which are sealed together, for example atseal 160. The top and bottom barrier layer are made of a material impervious to passage of the powder contained within the dispenser, and optionally are also a barrier to fluid but allow for the passage of air, or alternatively are gas tight. The top barrier layer includes dispensing holes (not illustrated) which are covered and sealed by a sealing layer, 150, on the top barrier layer. -
FIG. 2 illustrates a cross-section of the powder dispensing pad, 100, taken along line 1-1 shown inFIG. 1 . As illustrated, a powder, 170, is between the bottom sealing layer, 110, and a storage layer, 120. The storage layer is preferably a very porous non-woven material having loft. A metering layer, 130, separates the storage layer from the top barrier layer, 140. The storage layer helps hold the powder within the dispenser, delivering the powder slowly to the metering layer. The metering layer is preferably made of a material though which the powder cannot pass, except for the presence of pores through which the powder may pass. The density and size of the pores in the metering layer determines how much powder may be dispensed, and ensures that the powder is evenly dispensed across its surface. - Also illustrated in
FIG. 2 are optional sublayers of the top and bottom barrier layers, 140 and 110, respectively. Preferably, the top barrier layer includes anouter fabric sublayer 144 on aninner membrane 142; similarly the bottom barrier layer includes anouter fabric sublayer 114 on aninner membrane 112. The outer fabric layers provide a cloth-like feel to the exterior of thedispenser 100, while the inner membranes, preferably formed from a thin membrane of a polymeric material, prevent the passage of powder and optionally prevent the passage of fluid, or further optionally prevent the passage of air. In the case where the membranes contain a thermoplastic polymer film, then the seal, 160, made be made by heating while pressing the two membranes together. Also shown inFIG. 2 is an adhesive layer, 152, for adhering the sealing layer, 150, on the top barrier layer, 140, and thecontainer 190. -
FIGS. 3A and 3B illustrates the powder dispensing pad, 100, ofFIG. 1 , with the sealing layer removed, to reveal more detail of the top barrier layer, 140, and the metering layer, 130;FIG. 3B is an expanded view of the subsection ofFIG. 3A labeled “3B”. As show, the top barrier layer includes a plurality of holes, 146, through which the powder is dispensed. These holes are covered by the sealing layer inFIG. 1 . Visible through the holes, 146, is the metering layer, 130, which includes pores, 132, which are smaller than the holes in the top barrier layer. Also illustrated is the seal, 160, and the bottom barrier layer, 110. - In a variation, the top barrier layer, bottom barrier layer and the seal between them, are all gas tight. Furthermore, the sealing layer and the adhesive layer are also gas tight. When the sealing layer is applied, or when the seal is formed, whichever is carried out last, the powder dispensing pad is either flattened using pressure or is placed under low pressure gas. This will effectively create a vacuum or low pressure within the powder dispensing pad, which is maintained until the sealing layer is removed. Once opened, the storage layer will act as a spring, and expand the powder dispensing pad when the full loft of the storage layer returns. In this way, the powder dispensing pad will be thinner during storage, and prior to use.
- As illustrated in
FIG. 1 , the powder dispensing pad has an oval shape; other shapes, such as a square or a circle, are also possible. The size of the dispenser may be any size convenient for the user to hold. For example, as shown inFIG. 2 , the minor axis of the oval shaped dispenser, W2, may be for example 3 to 20 cm, more preferably 6 to 14 cm, and most preferably 8 to 10 cm, while the major axis (perpendicular to line 1-1 inFIG. 1 ) may be for example 4 to 27 cm, more preferably 8 to 19 cm, and most preferably 11 to 13 cm. The sealing layer covers the holes in the top barrier layer, and is appropriately shaped and sized. As illustrated inFIG. 1 , the sealing layer has an oval shape. For example, as shown inFIG. 2 , the minor axis of the oval shaped sealing layer, W1, may be for example 2.25 to 15 cm, more preferably 4.5 to 10.5 cm, and most preferably 6 to 7.5 cm, while the major axis (perpendicular to line 1-1 inFIG. 1 ) may be for example 3 to 20 cm, more preferably 6 to 14 cm, and most preferably 8 to 10 cm. - The thickness of the storage layer, illustrated in
FIG. 2 as t1, may be for example 1 to 5 mm, more preferably 2 to 4 mm. The total thickness of the dispenser, illustrated inFIG. 2 as t2, may be for example 0.5 to 5 mm greater than the thickness of the storage layer, t1. The diameter of the holes in the top barrier layer, illustrated inFIG. 3B as d2, may be for example 2 to 10 mm, including 3, 4, 5, 6, 7, 8 and 9 mm. The diameter of the pores in the metering layer, illustrated inFIG. 3B as d1, is always less than that of the holes in the top barrier layer, t2, and may be for example 0.2 to 3 mm, including 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.25, 1.5, 2 and 2.5 mm. The edge-to-edge distance between the holes in the top barrier layer, illustrated inFIG. 3A as s2, may be similar to the diameter of the holes, d2, and may be for example 2 to 10 mm, including 3, 4, 5, 6, 7, 8 and 9 mm. The edge-to-edge distance between the pores in the metering layer, illustrated inFIG. 3B as s1, may be similar to the diameter of the pores, d1, and may be for example 0.2 to 3 mm, including 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.25, 1.5, 2 and 2.5 mm. -
FIG. 4 illustrates a cross-section of a variation of a powder dispensing pad, similar topowder dispensing pad 100 taken along line 1-1 shown inFIG. 1 . In this variation, the powder, 170, is dispersed throughout the storage layer, 120. Other elements are the same as those illustrated inFIG. 2 . -
FIG. 5 illustrates another variation of a powder dispensing pad, 100, which does not include a sealing layer. Instead, the powder dispensing pad is folded so that one-half of the top barrier layer, 140, faces the other half of the top barrier layer. A seal, 180, is present on the top barrier layer, to maintain each half of the top barrier layer against each other, to prevent exposure of the holes, 146, and prevent escape of the powder. Prior to use, a user may break the seal and unfold the powder dispensing pad, exposing the holes, 146, to allow for application of the powder. Other elements of this variation of a powder dispensing pad are the same as that illustrated inFIGS. 1-4 (except for the absence of the sealing layer and adhesive layer). The seal, 180, may be made of the same adhesive as adhesive layer, 152, illustrated inFIG. 2 . -
FIG. 6 illustrates a cut-away view of another variation of a powder dispensing pad, 100, which does not include a sealing layer, but instead includes a cover layer, 350. The cover layer, 350, is on the top barrier layer, 140, and includes one or more lines of perforations, 380, such as a single line (illustrated), two parallel lines, or two perpendicular lines. The line or lines of perforations have a length which is less than a diameter of the top barrier layer, 140, and do not intersect an edge of the cover layer, 350. Prior to use, a user may tug apart the line or lines of perforations, separating the edges of the perforated line or lines, forming a gap in the cover layer. This gap will expose the underlying top barrier layer and holes, and the metering layer, to allow the user to dispense the powder. -
FIG. 7 illustrates a cut-away view of a pad dispenser, 400, for containing a plurality of powder dispensing pads, 100 (although only a single powder dispensing pad is present in the illustration). The pad dispenser, 400, includes a body, 430, and a lid, 420, which is movably attached to the body. At the top of the body is a top surface, 412, of the body which includes an opening, 410, through which a powder dispensing pad may be removed. The opening may have any shape, including a slit, or cross-shaped slits, as illustrate. In a variation, each of the powder dispensing pads may be attached to each other by a weak attachment, so that as a first powder dispensing pad is pulled out of the pad dispenser and through the cross-shaped slits, the next powder dispensing pad to which it is attached is pulled part-way through the slits before the weak attachment is broken. -
FIG. 8 illustrates a variation of a pad dispenser, 500, for containing a plurality of powder dispensing pads, 100 (although only a single dispenser is present in the illustration). The pad dispenser, 500, includes a body, 530. At the top of the body is a top surface, 512, of the body which includes an opening, 510, through which a powder dispensing pad may be removed. The opening as illustrated is a slit. In a variation, each of the powder dispensing pads may be attached to each other by a weak attachment, so that as a first powder dispensing pad is pulled out of the pad dispenser and through the slit, the next powder dispensing pad to which it is attached is pulled part-way through the slit before the weak attachment is broken. As illustrated, the powder dispensing pad is part-way through the slit. -

Preferably, the powder dispensing pad is intended for a single use, and preferably contains only enough powder for a single application, referred to as a unit dose. In the case of a cosmetic powder, the amount of powder is sufficient for a single application, also referred to as a unit dose. In the case of medicated powder, a single dosage of the medication is present in the powder, also referred to as a unit dose; when the powder dispensing pad contains a unit dose of medication, the powder dispensing pad may be referred to as a unit dosage form of the medication. In the case of a baby powder, the amount of powder is sufficient for a single application to a baby during a diaper change. Since not all the powder present in the powder dispensing pad will be dispensed during use, an excess of the powder may be included so that a unit dose of the powder is dispensed during use.
