  • the glove is also beneficially utilized for the purposes of food handling and in the health-care industry.
  • the glove is also completely biodegradable, capable of being effectively and safely transported or handled without degradation, and capable of being utilized by a user without inhibiting the functionality of a user’s hands.
  • the glove composition also prevents or inhibits a skin reaction or irritation that some known gloves also tend to produce.
  • a water-soluble and disposable glove having a glove body with a lower enclosed opening, defining an internal enclosed glove cavity spatially coupled to the lower enclosed opening and including a plurality of independently offset finger channels, wholly of a polymeric material having a composition including a polyvinyl acetate concentration within a range of 75-85% and including glycerin within a range of 10-20%, and having a uniform thickness within a range of approximately 0.01-0.05mm.
  • an embodiment of the present invention includes the plurality of independently offset finger channels being formed to an enclosed little finger channel, an enclosed ring finger channel, an enclosed middle finger channel, an enclosed index finger channel, and an enclosed thumb channel.

  • the terms “about” or “approximately” apply to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure. Unless otherwise stated herein, approximately may at least be interpreted as +/- 5mm if expressed in mm and +/- 2% if expressed in percentage. In this document, the term “longitudinal” should be understood to mean in a direction corresponding to an elongated direction of the glove, or in direction spanning from the bottom opening of the glove to the distal tips of the fingers. BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a water-soluble and disposable glove in accordance with one embodiment of the present invention
  • FIG. 2 is a top plan view of the water-soluble and disposable glove in FIG. 1 with an individual’s hand disposed therein; and
  • FIG. 3 is a cross-sectional view along section line 3-3 in FIG. 1.
  • the present invention provides a novel and efficient water-soluble and disposable glove that is capable of effective and quick dissolution in a small, approximately room temperature, body of water, like a toilet bowl. Embodiments of the invention also enable the glove to be effectively worn by the user without significant risk of tearing or failure.
  • FIGS. 1-3 one embodiment of the present invention is shown in a perspective view, elevational view, and cross-sectional view, respectively.
  • FIGS. 1-3 show several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components.
  • the first example of a water-soluble and disposable glove as shown in the figures, includes a glove body 102 with a lower enclosed opening 104 defined thereon and an internal enclosed glove cavity 200 defined therein and spatially coupled to the lower enclosed opening 104.
  • the lower enclosed opening 104 may be described as being at a terminal opposite end of the glove relative to one or more of the terminal end(s) of a plurality of independently offset finger channels 200a-n formed on the glove body 102. It should be understood that terms such as, “front,” “rear,” “side,” top,” “lower,” and the like are indicated from the reference point of a viewer viewing the glove body 102 as seen in the figures and may vary based on perspective.
  • the longitudinal length 202 separating a terminal end of an outer surface of the glove finger defining the middle finger channel 200c and the end of the glove body 102 defining the lower enclosed opening 104 may be approximately 266mm (or 10.5in ).
  • the diameter of the lower enclosed opening 104 may be approximately 152mm (or 6in.).
  • the width of the glove body 102 (from tip of the little finger to the tip of the thumb finger) may be approximately 228mm (or 9in.).
  • the glove body 102 may be formed with independent fingers for effective and conventional use of the user’s hands.
  • the plurality of independently offset finger channels 200a-n include an enclosed little finger channel 200a, an enclosed ring finger channel 200b, an enclosed middle finger channel 200c, an enclosed index finger channel 200d, and an enclosed thumb channel 200e.
  • the glove body 102 is beneficially shaped and sized to provide a universal (one size fits all) size glove for users having varying finger lengths and thicknesses.
  • the glove body 102 is preferably without any apertures or holes, such that it may be formed with a wall-like structure, i.e., continuous structures, as well as, separate structures that are coupled together so as to form a substantially continuous external surface.

  • compositions and thickness provide the requisite rigidity and toughness for the glove’s limited application while simultaneously providing effective and quick solubility in a body of water having approximate room temperature, e.g., 20-26°C (68-78°F).
  • the composition of the polymeric material of the glove body 102 preferably is made up of greater than approximately 78% concentration of polyvinyl acetate, less than approximately 15% of glycerin, less than approximately 8% of other additives, and approximately 4-8% water, wherein the total composition will equal 100%.
  • the glove body 102 has a uniform thickness in that the wall structure forming the fingers and palm portion glove (i.e., the whole glove) is the same, or at a maximum of a 5% thickness variance, of one another For example, looking at FIG. 3, the thickness 300 of the wall can be seen being approximately
  • the thickness is exactly 0.025mm (or 25microns and/or 100 gauge).
  • the glove body 120 along with a plurality of other glove bodies, will be preferably stored in packaging (e g , box) until desired for use. Once a glove has been removed from the package, the rest of the gloves will remain therein. In some embodiments, the gloves will be individually packaged, thereby protecting the gloves from environmental or ambient moisture.

  • the glove body 102 is at least of a translucent material, i.e., translucent, or transparent, to enable a user to see internal within the glove body 102.
  • the glove body 102 is solid or non-translucent and may have a slight odor.
  • the glove body 102 is designed such that it does not leave any toxic residue and has zero microplastics incorporated therein.
  • the polymeric material of the glove body 102 has physical properties that include a melting point greater than 150°C, a decomposition temperature greater than 200°C (but preferably around approximately 60°C), a pH of approximately 5-7 (4% weight sol. water), and a specific weight of approximately 1.1-1.3 g/mm3.
