Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] This invention has been made by the members of MIMURA
Seminar College of Law, Nihon Univ. as a team. The present
invention relates to a food and drink apparatus, and more
particularly to an environmentally friendly inside diameter
adjustable straw, having a convex member on its front surface and
concave member on its back surface.
2. Description of the related arts
[0002] Conventional straw's are simply straight elongated
cylinders. Plastic straws are mainly used, and if they are not
properly disposed of, they will become marine plastic garbage,
which will affect marine pollution and ecosystems.
[0003] In addition, since each type of beverage has its own
recommended inner diameter, it is necessary to manufacture multiple
straws, each having different inner diameters. For example, a
small-diameter straw is used for infants, while a large-diameter
straw is used for beverages containing tapioca However, under the
current straw market, there is no straws that can be suitable for
more than one type of beverage in one straw. Therefore, a straw
capable of serving multiple types of beverages was desired by
adjusting the inner diameter.
SUMMARY OF THE INVENTION
[0004] An object of the present invention is to solve the above
problem, and to provide an inside diameter adjustable straw flat
straw including a rectangular-shaped main body having front and
back surfaces; a first engagement member, which is formed on the
front surface of the main body and which is formed in a convex
shape being extended from one end of the main body to the opposite
end thereof; a second engagement member, which is formed on the
back surface, which is formed in a concave shape, and which is
formed parallel to the first engagement member: and a third
engagement member, which is formed on the back surface, which is
formed in a concave shape, and which is formed in parallel to the
second engagement member at a predetermined distance.
BRIEF DESCRIPTION OF DRAWINGS
[0005] The invention will be more specifically described with
reference to the accounting drawings, in which:
[0006] FIG. 1A is a perspective geometry net view of a straw of the
present invention;
[0007] FIG. 1B is a cross-sectional view of the straw shown in FIG.
1;
[0008] FIG. 2A is a perspective view of a large-diameter straw of
the present invention; and
[0009] FIG. 2B is a perspective view of a small-diameter straw of
the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] FIG. 1A is the perspective geometry net view showing an
overall concept according to an embodiment of the present
invention, and FIG. 1B is the cross-sectional view of the straw
shown in FIG 1A. A straw 100 shown in FIG. 1A and FIG. 1B includes
a rectangular-shaped main body 1 having front and back surfaces, a
first engagement member 2, which is formed on the front surface of
the main body 1 and which is formed in a convex shape being
extended from one end of the main body 1 to the opposite end
thereof, a second engagement member 3, which is formed on the back
surface, which is formed in a concave shape, and which is formed
parallel to the first engagement member 2, and a third engagement
member 4, which is formed on the back surface, which is formed in a
concave shape, and which is formed parallel to the second
engagement member 3 at a predetermined distance. The main body 1
and the first engagement member are formed in an integral structure
The main body 1 is made of silicon resin and has a thickness of
about 2 mm. Like the main body 1, the first engagement member 2 is
made of silicon resin. As shown in FIG. 1B, the first engagement
member 2 formed in a mushroom-shaped at its cross section, and the
width at its tip is slightly wider than that at its bottom being
connected to the main body 1. The height of the first engagement
member is set slightly lower than the thickness of the main body
1.
[0011] The concave shape of the second engagement member 3 is
almost the same shape as that of the first engagement member 2.
Therefore, the depth of the concave of the second engagement member
is set slightly less than the thickness of the main body 1. The
second engagement member 3 is formed about 3.3 cm away from the
first engagement member 2.
[0012] The third engagement member 4 has the same shape as the
second engagement member 3. The third engagement member 4 is formed
as close to the first engagement member 3 as 130 mm from the second
engagement member 3.
[0013] The straw 100 shown in FIG. 1A and FIG. 1B are used as
follows. As shown in FIG 2A and FIG. 2B, since a large-diameter
straw is required when drinking a tapioca-containing beverage or
the like, the first engagement member 2 is inserted into the second
engagement member to form a cylindrical shape. At this time, since
the first engagement member 2 and the second engagement member 3
are formed in the same shape and are made of elastic silicone
resin, the first engagement member 2 is fitted into the second
engagement member 3 by pressing the first engagement member 2 from
the back side after the first engagement member 2 and the second
engagement member 3 are coupled. By the process mentioned above,
the large-diameter straw with an inner diameter of 350 mm is
formed.
[0014] On the other hand, since a small-diameter straw is required
in the case of use by an infant, the first engagement member 2 is
inserted into the third engagement member 4 to form a cylindrical
shape. At this time, as well as in the case of forming the
large-diameter straw described above, the first engagement member 2
is fitted into the third engagement member 4 by pressing the first
engagement member 2 from the back side after the first engagement
member 2 and the third engagement member 4 are coupled By the
process mentioned above, the small-diameter straw with an inner
diameter of 220 mm is formed. As described above, the straw 100
formed by the above-mentioned process can be used to carry the
drink to the mouth.
[0015] In the above embodiment, a main body 1 is used for the straw
100, which can make two different inner diameters, out by
increasing the number of concave member, a straw with more than
three different inner diameters can be formed.
[0016] While the invention has been described with reference to
illustrative embodiments, this description is not intended to be
construed in a limiting sense. Thus, shapes, size and physical
relationship of each component are roughly illustrated so the scope
of the invention should not be construed to be limited to them.
Further, to clarify the components of the invention, hatching is
partially omitted in the cross-sectional views. Moreover the
numerical description in the embodiment described above is one of
the preferred examples in the preferred embodiment so that the
scope of the invention should not be construed to limit to
them.
[0017] Various other modifications of the illustrated embodiment
will be apparent to those skilled in the art on reference to this
description. Therefore, the appended claims are intended to cover
any such modifications or embodiments as fall within the true scope
of the invention.
