Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Patent Application 63/054,615, filed on Jul. 21, 2020, and
incorporated herein by reference.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND
DEVELOPMENT
[0002] Not applicable.
FIELD OF THE INVENTION
[0003] The invention relates to a toy product, preferably a plush
toy product, with antimicrobial properties that permit it to resist
odors and stains even after repeated washings and a method for
manufacturing the same.
BACKGROUND
[0004] Plush toy products are a staple of the toy industry and have
been marketed and used by children for generations. One of the
inherent problems with any toy product, particularly one that has a
plush outer surface, is that it can become a collector of various
bacteria and viruses which can then be spread to the users.
[0005] The parents of children, particularly during a pandemic, are
particularly sensitive to this problem. Therefore, there is a need
for such a plush toy product that has antimicrobial properties that
permit it to resist odors and stains. Since these products are
frequently washed or cleaned by the parents of the users, the plush
product must be able to maintain its antimicrobial properties after
repeated washings.
[0006] Manufacturers of toy products, particularly plush toy
products, have attempted to address this problem in the past
although most, if not all, have been unsuccessful. Some
manufacturers have attempted to simply apply an antimicrobial agent
to the finished products which quickly wore off during use and
after an initial washing because it was not embedded in the matrix
of the products. Other attempts failed because they were either
ineffective to prevent microbial growth or, worse yet, because they
were considered unsafe to the children who would be playing with
the toy product. To be considered effective and safe, these
products needed to pass both efficacy and safety tests.
[0007] Examples of such prior art attempts include, for example,
WO0002636 (A1) for Sanitary Finished Stuffed/Plush Toy and its
Manufacturing Method in which a finished stuffed/plush) toy is
treated with an antibacterial chemical alter fabrication rather
than during the manufacturing process.
[0008] See also JP2008065705A for Deodorant Stuffed Toy where,
again, the antimicrobial agent is sprayed onto the finished toy
product after manufacture and CN102500110A for Antibacterial Fabric
for Plush Toy where, again, the antimicrobial agent is not
introduced during the manufacturing process.
[0009] In U.S. Pat. No. 6,240,879 for an Amusement Articles
Possessing Microbe-Inhibiting Properties, a pet toy product
including microbe-inhibiting properties is taught and identifies a
host of different microbe-inhibiting agents, many of which are
banned by the FDA due, no doubt, to the fact that the intended use
of the product is for domestic animals, not children.
SUMMARY OF THE INVENTION
[0010] The toy product of the present invention incorporates an
antimicrobial agent that is introduced during the manufacturing
process, to render the resultant product fresh, hypoallergenic, and
resistant to stains and odors during use, even after repeated
washings.
[0011] In a preferred embodiment, the toy product is a stuffed
plush animal in which some or all of the yarn/fabric used in
fabricating the toy product is treated with an antimicrobial agent
during the knitting of the yarn to create the plush. While several
different antimicrobial agents may be used, a preferred
antimicrobial agent is a solution selected from the group
consisting of silver nitrate, pyrithione zinc, 3-(trimethoxysilyl)
propyl dimethyl octadecyl ammonium chloride, cupric ion, zinc
oxide, dimethyl distearylammonium chloride, and polyhexamethylene
guanidine hydrochloride and phosphate.
[0012] According to the method of the present invention, the
antimicrobial agent is preferably introduced into a water tank
after the weaving and dying step and prior to the creation of the
plush fabric used for the top product.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a flow chart that describes the steps in the
process of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0014] The toy product of the present invention, preferably in the
form of a stuffed plush animal, is made from a super soft, plush
material that is treated with an antimicrobial agent during the
manufacturing process to render it safe, stain-resistant, and
washable up to as many as 10 to 20 industrial washings without
losing its antimicrobial properties. Such a product is safe for
both humans and pets. The product can similarly be used for other
toys, gifts, and novelty products including, blankets, pillows,
decorative pillows, travel products, seasonal products, pet toys,
and baby products.
[0015] To achieve its antimicrobial properties, the yarns or fabric
used in fabricating the plush animal are woven, dyed, and then
treated with the antimicrobial agent followed by exposure to
elevated temperatures to cure or otherwise set the antimicrobial
agent. Polyester is the best material for accepting the
antimicrobial treatment although cotton, acrylic, and nylon also
have a good acceptance level. The resultant fabric can then be
knitted or woven to form the plush toy. While the antimicrobial
agent may be introduced during the dying process, it has been found
that it is more commercially effective to add such antimicrobial
agent after the dying process. Alternatively, the antimicrobial
agent can be sprayed or coated on the fabric or yarn. The spraying
process can be treated by brush, ordinary hand pressure sprinkler,
air pressure spray gun, special spray machine, etc., and it does
not need high-temperature baking and natural air drying at normal
temperature.
[0016] The antimicrobial agents used herein are added in varying
concentrations depending upon the specific antimicrobial agent
selected. In almost all instances, they are diluted with water to
achieve their desired effect. The specific antimicrobial agents
used are generally effective in concentrations between 0.2% and
10%.
[0017] While several different antimicrobial agents may be used, it
has been found that antimicrobial agents, including silver nitrate,
silver chloride, and/or alkyl dimethyl benzyl ammonium chloride are
particularly effective antimicrobial agents, preferably in
combination with alkyl (50% C12, 30% C14, 17% C16, 3% C18) dimethyl
benzyl ammonium chloride.
[0018] An antimicrobial solution of between about 0.2% and 0.6%
silver nitrate mixed with between about 0.75% and 1.25% of alkyl
(50% C12, 30% C14, 17% C16, 3% C18) Dimethyl Benzyl Ammonium
Chloride is a very effective antimicrobial agent and may be used in
concentrations of between about 1% and 10% when mixed with water. A
particularly preferred concentration range is between about 3% and
5% when mixed with water.
[0019] Such silver nitrate antimicrobial agents are available
commercially, including the commercial product known as SilverClear
solution for the treatment of textiles which is marketed by
TransTex Technologies of Montreal, Canada. It is supplied at a
concentration of about 1% silver nitrate and Dimethyl Benzyl
Ammonium Chloride. SilverClear does not contain any Substances of
Very High Concerns (SVHC) as defined in Article 57 of the EU's
REACH Regulation and as published by ECHA through Jun. 1, 2020.
[0020] Toy products treated with silver nitrate antimicrobial
agents have demonstrated a significant anti-bacterial reduction
with Staphylococcus aureus and Klebsiella pneumonia, typically
above a 99% reduction in bacterial growth. More significantly,
after 10 washes in a normal cycle and normal tumble dry cycle, the
products retained a 95% reduction in bacterial growth with
Staphylococcus aureus and 87.5% with Klebsiella pneumonia and
passed all appropriate toy safety tests. See, for example, the test
results in Example 1.
[0021] Another acceptable antimicrobial agent that may be used
includes pyrithione zinc in concentrations between about 0.2% and
about 10% and, preferably between about 1% and 3% when mixed with
water. One particularly preferred pyrithione zinc antimicrobial
agent is the commercial product known as Sanitized marketed by
Sanitized AG of Burgdorf, Switzerland which is supplied at a
concentration of about 30% pyrithione zinc.
[0022] Toy products treated with pyrithione zinc antimicrobial
agents have demonstrated a 99% reduction in the growth of
Staphylococcus aureus and Klebsiella pneumonia. More significantly,
after 20 washes in a normal cycle and normal tumble dry cycle, the
products retained a 99.9% reduction in bacterial with both
Staphylococcus aureus and Klebsiella pneumonia and passed all
appropriate toy safety tests. See, for example, the test results in
Example 2.
[0023] Yet another acceptable antimicrobial agent that may be used
is 3-(trimethoxysilyl) propyldimethyloctadecy ammonium chloride in
concentrations between about 0.2% and about 10% and, preferably, in
concentrations between about 2% and 3%. One particularly preferred
3-(trimethoxysilyl) propyldimethyloctadecy ammonium chloride
antimicrobial agent is the commercial product known as Microban by
Microban International Ltd. of Huntersville, N.C. Microban is
supplied at a concentration of about 42% 3-(trimethoxysilyl)
propyldimethyloctadecy ammonium chloride.
[0024] Toy products treated with 3-(trimethoxysilyl)
propyldimethyloctadecy ammonium chloride antimicrobial agents have
demonstrated a 99% reduction anti-bacterial with Staphylococcus
aureus and a 97.7% reduction with Klebsiella pneumonia and it
passed all appropriate toy safety tests. See, for example, the test
results in Example 3.
[0025] Other possible antimicrobial agents that can be used
include, for example, cupric ion, zinc oxide, dimethyl
distearylammonium chloride, and polyhexamethylene guanidine
hydrochloride and phosphate, preferably in concentrations between
about 0.2% and about 10%. Products so tested under normal
conditions reported a 99% reduction anti-bacterial with
Staphylococcus aureus and Klebsiella pneumonia and passed all
children's safety tests. See, for example, the actual test results
in Examples 4 through 7.
[0026] The process of the present invention is best described in
the flow chart of FIG. 1. After the weaving and drying of the yarn
in Steps 1 and 2, the antimicrobial agent of the present invention
is added to the tank and diluted with water in Step 3 as described
above so that the fabric absorbs the antimicrobial agent. It then
passes through an industrial oven as described in Step 4 for
between 45 and 60 seconds at a temperature of between 170.degree.
and 180.degree. C. The resultant and treated yarn in Step 5 can
then be processed into the plush animal toy of the present
invention. In an alternative embodiment, the antimicrobial agent
can be added to the yarn fibers before they are spun into yarn or
to the yarn before it is knitted or woven.
