Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a non-provisional patent application of
and claims the benefit of the filing dates of U.S. provisional
patent application No. 62/865,043, filed on Jun. 21, 2019.
FIELD
[0002] The present disclosure relates to a straw apparatus, in
particular, to a straw apparatus comprising identical half-straw
sections.
BACKGROUND
[0003] As used herein, a "straw" is a hollow conduit that is longer
in length than it is across a top of the conduit. Straws are often
used to consume liquids. Historically, straws have been made from
plant stems, paper, plastic, glass, and metal.
[0004] Human consumers (collectively referred to herein as,
"consumers") of liquid or fluid (collectively referred to herein
as, "beverage") sometimes use a straw to consumer a beverage. The
reasons for this may range from aesthetic, such as a straw used by
a partygoer to consume a cocktail, to practical, such as a straw
used by a person in a reclined or semi-reclined position, such as a
laying person, to consume a beverage from a cup or glass.
[0005] However, plastic straws are seldom reused. Typically,
plastic straws are used once, then discarded.
[0006] Alternatives to disposable plastic straws including, for
example, disposable paper straws, disposable straws made out of a
"compostable" or "biodegradable" material, straws made out of a
"recyclable" material (though many "biodegradable" and "recyclable"
materials have shortcomings), and reusable straws made out of a
material which may be washed. Examples of materials use to make
reusable straws include stainless steel, glass, bamboo, and wood
straws, all of which are generally rigid. Many reusable straws are
sold with brushes that are intended to be used to brush the
interior of the straw during a cleaning process. Such brushes
highlight that merely washing a reusable straw in a dish washing
machine may not clean the interior of the straw, but that it may be
necessary or desirable to clean the interior of the straw with a
brush. Cleaning a straw with a brush requires time and work and the
brush should also be cleaned and stored.
[0007] Alternatives to disposable straws also include a straw
apparatus which comprise two non-identical sections, in other
words, a first non-identical section, section A, which is different
from a second non-identical section, section B. However, because
they are different, section A and section B must be kept and used
together. In other words, two section A's may not be joined to form
a straw apparatus; section A must be joined to a section B to form
a straw apparatus. Consequently the two non-identical sections must
be kept together in order to form straws, in order to reduce effort
expended in matching the two sections during the straw assembly
process, and to reduce waste which may occur when two matching
sections are not found together during the straw assembly process
("mis-match waste").

DETAILED DESCRIPTION
[0022] Following are defined terms in this document.
[0023] As used herein, the term "parallel projection" refers to
projection of an object in three-dimensional space onto a fixed
two-dimensional plane, known as a projection plane or image plane,
where rays, known as lines of sight or projection lines, are
parallel to each other.
[0024] As used herein, the term "perspective projection" refers to
projection of an object in three-dimensional space onto a fixed
two-dimensional plane, known as a projection plane or image plane,
where rays, lines of sight, or projection lines, converge toward a
"vanishing point".
[0025] As used herein, the term, "isomorphic projection" refers to
a projection, in which three coordinate axes of three-dimensional
space appear in the image plane to be equally foreshortened and the
angle between any two of them is 120 degrees.
[0026] As used herein, "occlude" means to stop, close up, or
obstruct an opening, orifice, channel, or passage.
[0027] As used herein, "distal" describes an element which is
further from a center or central axis of an assembled straw
apparatus.
[0028] As used herein, "proximal" describes an element which is
closer to a center or central axis of an assembled straw
apparatus.
[0029] Singular references herein to one element in the drawings or
to any object or noun shall be understood to refer to one or more
unless the context makes clear otherwise. When an element in the
drawings is followed by a letter, as in, "105A" and "105B", the two
elements are meant to be physically identical, though their
configuration or arrangement may be different.
[0030] As used herein, a "trapezoid" is a quadrilateral with one
pair of parallel sides.
[0031] As used herein, an "isosceles trapezoid" is a trapezoid in
which two base angles and two side lengths are equal and in which
two end lengths are not equal.
[0032] When lengths or other dimensions are discussed herein, all
such lengths or other dimensions shall be understood to be nominal
values, within expected or normal manufacturing ranges.
[0033] In overview, this disclosure relates to a straw apparatus.
The straw apparatus may be separated into two sections; each such
section is referred to herein as a "separable straw section". The
separable straw sections may be washed, such as when they are
separated. The separate straw sections are identical.
[0034] A first separable straw section may be joined to a second
separable straw section by a closure mechanism. The closure
mechanism may be integrated into the separable straw section. The
closure mechanism may comprise interlocking members. The
interlocking members may have cross-section closure profiles
comprising a female-type closure profile and a male-type closure
profile.
[0035] The female-type closure profile may also be referred to as a
clasp; the female-type closure profile may be described herein as
comprising a female interlocking member or clasp cavity and a
female seal face, wherein the female seal face comprises a distal
female seal face and a proximal female seal face, wherein the
female seal faces are separated by the female interlocking member
or clasp cavity.
[0036] The male-type closure profile may be described herein as
comprising a male interlocking member or protuberance, and a male
seal face, wherein the male seal face comprises a distal male seal
face and a proximal male seal face, wherein the male seal faces are
separated by the male interlocking member.
[0037] The female and male seal faces may, though do not have to,
lie on a common plane; the female and male seal faces on a
separable straw section may be separated by a passage. The passage
between the female and male seal faces on the separable straw
section may be "U" shaped or another shape which, when sealed to a
mirror image of itself in the straw apparatus assembly process,
forms a central channel through which fluid may be drawn. A round
channel may have hydrodynamic properties which make it beneficial
for a straw apparatus, though a round channel is not necessary.
[0038] The male interlocking member or protuberance may fit within
and occlude the female interlocking member or clasp cavity. The
female interlocking member or clasp cavity may be larger than the
male interlocking member or protuberance. The separable straw
sections may be formed of a flexible material, such as silicone
with a Shore hardness, such as between 60 and 70 for silicone.
Other flexible materials may be used, such as urethane, rubber, or
the like. The material and Shore hardness thereof may be selected
such that the male interlocking member may be repeatedly inserted
within or removed from the female interlocking member, without
breaking or tearing of either of the interlocking members and such
that the deformations which may occur during the insertion process
may relax without ejecting the male interlocking member from the
female interlocking member and without distorting the seal
faces.
[0039] When viewed from above, down a y-axis, a first separable
straw section may be rotated one-hundred and eighty degrees around
the y-axis relative to a second separable straw section, such that
the female interlocking member of the first separable straw section
aligns with the male interlocking member of the second separable
straw section. When aligned, during a straw assembly process, the
first and second separable straw sections may be squeezed or
pinched together, such as by human fingers, such that the male
interlocking member of one separable straw section occludes the
female interlocking member of the other.
[0040] When the closure mechanism of two separable straw sections
is locked or secured, the female seal faces of one separate straw
section are held against the corresponding male seal faces of the
other separable straw section, sealing the passages of the two
separable straw sections together, forming a channel within the
assembled straw apparatus and a seam between the separable straw
sections. The seal created by the closure mechanism of the
separable straw sections may allow a human to draw a low pressure
area at one end of an assembled straw apparatus, drawing a fluid or
liquid into and up the channel of the assembled straw section.
Leakage of air along the length of seams of the closure mechanism
may occur, though may be tolerable or desirable by users and may
nonetheless allow a fluid to be drawn up the channel into a mouth
of the user.
[0041] Unlike prior art in which separable straw sections of a
straw apparatus are different from one another, the separable straw
sections disclosed herein may be identical, which allows assembly
of a straw apparatus from such separable straw sections without
regard to whether the separable straw sections are compatible with
one another. Use of identical separable straw sections also allows
two differently colored and or patterned separable straw sections
to be used together and interchangeably in straw apparatuses,
providing aesthetic or information transmission functions to the
disclosed straw apparatus.
[0042] In this way, a straw apparatus comprised of a first
separable straw section and a second separable straw section may be
separated into separate separable straw sections, the separable
straw sections may be washed or otherwise handled separately, the
separated separable straw sections may be closed via a closure
mechanism which is easy to use, and wherein the separable sections
are identical and may be used without regard to whether the
separable straw sections are compatible with one another.
[0043] FIG. 1 is a top perspective projection of a straw apparatus
100 incorporated with teachings of the present disclosure,
according to some embodiments. Straw apparatus 100 comprises a
first separable straw section 105A and a second separable straw
section 105B. The first and second separable straw sections 105 are
identical. When viewed from above down the y-axis, one of the first
and second separate straw sections 105 may be rotated, one relative
to the other, by one-hundred and eighty degrees around the y-axis.
The first and second separable straw sections 105 may be joined by
a closure mechanism 126. When joined, as in FIG. 1, straw apparatus
100 comprises channel 120. Channel 120 may be a width or diameter
of a standard straw; for example, channel 120 may have a diameter
of 3 to 15 mm. Separable straw section 105A comprises channel face
110A and external face 115A; separable straw section 105B comprises
channel face 110B and external face 115B. Straw apparatus 100
further comprises seam 117, where separable straw sections 105A and
105B contact one another and form a seal.
[0044] FIG. 2 is a top perspective projection of separable straw
section 105, incorporated with teachings of the present disclosure,
according to some embodiments. Separable straw section 105
comprises female interlocking member 130 and male interlocking
member 135; together, the interlocking members form the closure
mechanism. Separable straw section 105 may have separable straw
section length 125. For example, separable straw length 125 may be
approximately 100 mm to 260 mm; however, separable straw section
length may be much longer, for example, on the order of 1300 mm,
for example, when straw apparatus 100 is used to draw liquid from a
water bladder. It is very difficult to clean a conventional tube
which may span between a water bladder and a consumer.
[0045] FIG. 3 is a parallel projection of a plan view of an end of
a separable straw section 105, incorporated with teachings of the
present disclosure, according to some embodiments. In the example
embodiment illustrated in FIG. 3, separable straw section 105 is
illustrated as comprising female-type closure profile 160 and
male-type closure profile 150. Between ends of the closure
profiles, separable straw section 105 comprises an example of
passage 199. Passage 199 may have another shape, such as a
half-oval or another shape.
[0046] Within female-type closure profile 160, separable straw
section 105 comprises female interlocking member distal seal face
170 and female interlocking member proximal seal face 175, which,
together, may be referred to herein as, "female seal faces". Also
within female-type closure profile 160, separable straw section 105
comprises female interlocking member internal terminus 180.
Spanning between female interlocking member internal terminus 180
and the female seal faces 170 and 175 are illustrated examples of
female interlocking member internal distal wall 185 and female
interlocking member internal proximal wall 190. As illustrated in
this example, an approximate isosceles trapezoid is formed between
female interlocking member internal distal wall 185, female
interlocking member internal proximal wall 190, female interlocking
member internal terminus 180, and an imaginary line (not
illustrated) between ends of female seal faces 170 and 175;
however, it is not necessary that these structures form an
isosceles trapezoid. Another shape, for example, one comprising a
cavity that may be occluded by a male-type member and which may
apply a clamping force on such male-type member may be used.
[0047] Within male-type closure profile 150, separable straw
section 105 comprises male interlocking member distal seal face 203
and male interlocking member proximal seal face 201, which,
together, may be referred to herein as, "male seal faces". Also
within male-type closure profile 150, separable straw section 105
comprises male interlocking member terminus 195. Spanning between
male interlocking member terminus 195 and the male seal faces 201
and 203 are illustrated examples of male interlocking member distal
wall 205 and male interlocking member proximal wall 200. As
illustrated in this example, an approximate isosceles trapezoid is
formed between male interlocking member distal wall 205, male
interlocking member proximal wall 200, male interlocking member
terminus 195, and an imaginary line (not illustrated) between ends
of male seal faces 201 and 203; however, it is not necessary that
these structures form an isosceles trapezoid. Another shape
comprising a protuberance that may occlude a female-type member,
and which may be subject to a clamping force from a female-type
member may be used.
[0048] FIG. 4 is the parallel projection of the plan view of the
end of separable straw section 105 of FIG. 3 with additional
elements identified, incorporated with teachings of the present
disclosure, according to some embodiments. A reader may switch
between FIGS. 3 and 4, viewing one full page at a time, to see
commonalities between these Figures. In FIG. 4, male interlocking
member terminus 195, which may also be referred to herein as,
"protuberance maximum span", is illustrated as having length 196
while an imaginary line (not illustrated) between male seal faces
201 and 203, which may also be referred to herein as, "protuberance
minimum span", is illustrated as having length 197. In FIG. 4,
female interlocking member internal terminus 180, which may also be
referred to herein as, "clasp maximum span", is illustrated as
having length 181 while an imaginary line (not illustrated) between
female seal faces 170 and 175, which may also be referred to herein
as, "clasp minimum span", is illustrated as having length 182.
Length 197 of protuberance minimum span may be selected, according
to, for example, a material of separable straw section 105, such as
silicone, and a Shore hardness of such material, such as between 60
and 70, to provide a strength of male interlocking member such that
male interlocking member may be repeatedly inserted into and
withdrawn from female interlocking member, resisting clamping force
from female interlocking member, without tearing or separating from
separable straw section 105. In the example illustrated FIG. 4,
length 197 may be on the order of, for example, 1 mm.
[0049] FIG. 5 is a parallel projection of a plan view of a
separable straw 100, incorporated with teachings of the present
disclosure, according to some embodiments. Separable straw 100
comprises separable straw sections 105A and 105B, discussed
elsewhere herein. In FIG. 5, protuberance maximum span length 196
is illustrated as fitting within the larger space of clasp maximum
span length 181. In FIG. 5, protuberance minimum span length 197 is
illustrated as fitting within the larger space of clasp minimum
span length 182.
[0050] As illustrated in these examples, the difference between
length 197 and length 182, and between length 196 and length 181,
may be, for example, 0.005 mm. When the male interlocking member or
protuberance is inserted within the female interlocking member or
clasp, this difference allows the protuberance to remain with the
clasp, not be ejected by the clasp, and not distort the walls of
the clasp. For example, if an insufficient amount of room is
provided, protuberance may distort within or when inserted into
clasp, such as due to folding back of edges of protuberance or
other deformation of protuberance, and/or clasp may distort around
protuberance. Distortion of clasp and/or protuberance may result in
protuberance occupying an excessive volume within clasp, distortion
of clasp, distortion of clasp resulting in interference with
formation of a seal between the seal faces, and/or distortion of
protuberance may result in protuberance backing out of or being
ejected from clasp, such as when the distortions relax.
[0051] FIG. 6 is the parallel projection of the plan view of the
end of separable straw section 105 of FIG. 3 with additional
elements identified, incorporated with teachings of the present
disclosure, according to some embodiments. In the example
illustrated in FIG. 6, female seal face is of length 220; female
distal seal face is of length 210; and female proximal seal face
215 is of length 215. In the example illustrated in FIG. 6, male
seal face is of length 225; male distal seal face is of length 235;
and male proximal seal face is of length 230. Female seal face
length 220 may be equal to male seal face length 225. In the
example illustrated in FIG. 6, the distal and proximal seal faces
are not equal, though, in another embodiment, they may be.
[0052] FIG. 7 is the parallel projection of the plan view of the
end of separable straw section 105 of FIG. 3 with additional
elements identified, incorporated with teachings of the present
disclosure, according to some embodiments. In the example
illustrated in FIG. 7, female-type closure profile 160 comprises
clasp distal finger 240 and clasp proximal finger 245. Clasp distal
finger 240 and clasp proximal finger 245 may provide clasp force
250, resisting deformation of female-type closure profile 160 when,
for example, male interlocking member or protuberance 135 is
inserted into female interlocking member or clasp cavity 130. Clasp
force 250 may hold an inserted male interlocking member or
protuberance 135 within female interlocking member or clasp cavity
130.
[0053] In the example illustrated in FIG. 7, male interlocking
member or protuberance 135 may provide protuberance expansion force
255. Protuberance expansion force 255 may resist deformation of
male interlocking member or protuberance 135 when male interlocking
member or protuberance 135 is inserted into female interlocking
member or clasp cavity 130.
[0054] FIG. 8 is the parallel projection of the plan view of the
