Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] Pursuant to 35 U.S.C. .sctn. 119 and the Paris Convention
Treaty, this application claims foreign priority to Chinese Patent
Application No. 202120269694.4 filed Jan. 29, 2021, the contents of
which, including any intervening amendments thereto, are
incorporated herein by reference. Inquiries from the public to
applicants or assignees concerning this document or the related
applications should be directed to: Matthias Scholl P.C., Attn.:
Dr. Matthias Scholl Esq., 245 First Street, 18th Floor, Cambridge,
Mass. 02142.
BACKGROUND
[0002] The disclosure relates to the field of bedding, and more
particularly, to a mattress topper.
[0003] A mattress topper is a removable bedding that sits on the
top of a mattress to prevent dirt and damage to the mattress.
[0004] A filler in the top of the mattress topper is often squeezed
and deformed, which reduces the level of comfort for the user.
[0005] Existing mattress toppers have poor air permeability and
moisture dissipation, which lead to mildew and bacteria
breeding.
SUMMARY
[0006] The disclosure provides a mattress topper comprising a
cover; the cover comprises a top fabric, a bottom fabric, and a
plurality of gusseted sidewalls.
[0007] The plurality of gusseted sidewalls comprises a first edge
connected to the top fabric, and a second edge connected to the
bottom fabric; and the plurality of gusseted sidewalls is stitched
to a skirt.
[0008] The cover further comprises a filler layer comprising
polyester fiber and polyurethane sponge; and the filler layer is
connected to the cover by quilting.
[0009] In a class of this embodiment, the top fabric comprises
woven fabric, knitted fabric, or non-woven fabric, and the fabric
weight is within the range of 80-350 g/m.sup.2; the bottom fabric
comprises woven fabric, knitted fabric, or non-woven fabric, and
the fabric weight is within the range of 50-110 g/m.sup.2.
[0010] In a class of this embodiment, the plurality of gusseted
sidewalls is in the shape of a circular arc surface.
[0011] In a class of this embodiment, the skirt comprises a bottom
edge and a circular elastic band disposed on the bottom edge.
[0012] In a class of this embodiment, the polyester fiber in the
filler layer has a thickness of 0.7-15 D and a length of 32 mm, 51
mm, or 64 mm; the polyurethane sponge is not limited to
specifications, shapes and sizes.
[0013] In a class of this embodiment, a mixing ratio by mass of the
polyester fiber to the polyurethane sponge is 1:1, 8:2, 7:3, or
6:4.
[0014] In a class of this embodiment, the cover is connected to the
filler layer by quilting to form a regular pattern, such as a
square, a rectangle, a diamond, or a wavy line.
[0015] The following advantages are associated with the mattress
topper of the disclosure:
[0016] 1. The filler layer is connected to the cover by quilting
thus preventing the polyester fiber and the polyurethane sponge
from sliding and being squeezed, thereby enhancing the level of
comfort for the user.
[0017] 2. The top fabric of the mattress topper has a higher
density than related art, which makes the fabric more comfortable
to the touch. The bottom fabric of the disclosure has a lower
density than related art, which leads to better air permeability
and moisture dissipation, as well as reduced possibility of mildew
and bacteria breeding on the mattress topper.
[0018] 3. The plurality of gusseted sidewalls is in the shape of a
circular arc surface. When compressed, the cover is squeezed to
both sides, whereas the plurality of gusseted sidewalls due to good
elasticity can bear a greater squeezing force, which prevents the
cover from being deformed under pressure.
[0019] 4. The skirt comprises a bottom edge and a circular elastic
band disposed on the bottom edge so as to secure the mattress
topper to a mattress, thereby preventing the mattress topper from
sliding.
[0020] 5. The polyurethane sponge is not limited to specifications,
shapes and sizes, thereby minimizing waste of the polyurethane
sponge and saving costs.
[0021] 6. The cover is connected to the filler layer by quilting to
form a regular pattern, such as a square, a rectangle, a diamond,
or a wavy line, thereby giving an improved visual aesthetic.
BRIEF DESCRIPTION OF THE DRAWINGS
[0022] FIG. 1 is a perspective view of a mattress topper according
to one embodiment of the disclosure; and
[0023] FIG. 2 is a cross-sectional view of a mattress topper
according to one embodiment of the disclosure.
[0024] In the drawings, the following reference numbers are used:
1. Cover; 1.1. Top fabric; 1.2. Bottom fabric; 1.3. Gusseted
sidewall; 2. Skirt; 3. Filler layer; and 4. Elastic band.
DETAILED DESCRIPTION
[0025] To further illustrate, embodiments detailing a mattress
topper are described below. It should be noted that the following
embodiments are intended to describe and not to limit the
disclosure.
[0026] Referring to FIGS. 1-2, a mattress topper comprises a cover
1 comprising a top fabric 1.1, a bottom fabric 1.2, and a plurality
of gusseted sidewalls 1.3;
[0027] The plurality of gusseted sidewalls 1.3 comprises a first
edge connected to the top fabric 1.1 and a second edge connected to
the bottom fabric 1.2. The plurality of gusseted sidewalls 1.3 is
stitched to a skirt 2.
[0028] The cover 1 further comprises a filler layer 3 comprising
polyester fiber and polyurethane sponge. The filler layer 3 is
connected to the cover 1 by quilting.
[0029] Compared with related art, the filler layer 3 is connected
to the cover 1 by quilting to prevent the polyester fibers and the
polyurethane sponge from sliding and being squeezed, thereby
improving the comfort of the mattress topper. The mattress topper
is practicable to be used instead of a bed sheet.
[0030] The top fabric 1.1 comprises woven fabric, knitted fabric,
or non-woven fabric; and the fabric weight is within the range of
80-350 g/m.sup.2. The bottom fabric 1.2 comprises woven fabric,
knitted fabric, or non-woven fabric, and the fabric weight is
within the range of 50-110 g/m.sup.2. The top fabric 1.1 has a
higher density than the related art, which makes the fabric more
comfortable to the touch. The bottom fabric 1.2 has a lower density
than the related art, which leads to better air permeability and
moisture dissipation, as well as reduced possibility of mildew and
bacteria breeding on the mattress topper.
[0031] The plurality of gusseted sidewalls 1.3 is in the shape of a
circular arc surface. When compressed, the cover 1 is squeezed to
both sides and the plurality of gusseted sidewalls 1.3 due to good
elasticity can bear a greater squeezing force, which prevents the
cover 1 from being deformed under pressure.
[0032] The skirt 2 comprises a bottom edge and a circular elastic
band 4 disposed on the bottom edge so as to secure the mattress
topper to a mattress, thereby preventing the mattress topper from
sliding.
[0033] The polyester fiber in the filler layer 3 has a thickness of
0.7-15 D and a length of 32 mm, 51 mm, or 64 mm. The polyurethane
sponge is not limited to specifications, shapes and sizes, thereby
minimizing waste of the polyurethane sponge and saving costs.
[0034] A mixing ratio by mass of the polyester fiber to the
polyurethane sponge is 1:1, 8:2, 7:3, or 6:4, which retains the
supportability of the polyester fiber and the resilience of the
polyurethane sponge, thereby enhancing the level of comfort for the
user.
[0035] The cover 1 is connected to the filler layer 3 by quilting
to form a regular pattern, such as a square, a rectangle, a
diamond, or a wavy line, thereby giving an improved visual
aesthetic.
[0036] It will be obvious to those skilled in the art that changes
and modifications may be made, and therefore, the aim in the
appended claims is to cover all such changes and modifications.
