Integrally Formed Paper Straw with Pointed Head
Abstract
A pointed paper straw includes a paper straw (20) which is
integrally formed with a pointed head (202) and an overlapping
portion (201). The paper straw is formed by a paper mold sheet
(220) which is formed by a residual edge (22) of a paper material
(2). The residual edge has an end which has a left side and a right
side that are cut symmetrically, with two triangular pieces (221)
being removed, to form the paper mold sheet which includes a
pointed portion (2201). The paper mold sheet has a left side and a
right side that are curled inward and are overlapped and connected
to form the overlapping portion.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a paper product and, more
particularly, to a paper straw used for drinking beverage.
2. Description of the Related Art
[0002] A straw has a tubular shape with a pointed head that pierces
the film of a filmed cup to facilitate a user drinking the beverage
in the filmed cup. However, the conventional straw is made of
plastic material, thereby causing an environmental problem. Another
conventional straw is made of stainless steel to replace the
plastics. However, such a straw is not washed and cleaned easily.
In addition, the straw made of stainless steel is hard and causes
danger to the children. A conventional paper straw comprises a
paper sheet that is wound and coiled to form a helical structure
whose two axial ends are connected to each other. The helical
structure has edges partially overlapping, and the overlapping
portions are adhered by glue or adhesive. However, the conventional
paper straw has complicated procedures of fabrication, thereby
increasing the cost of production. In addition, the conventional
paper straw has a smooth circular distal end that cannot pierce the
film of the filmed cup, thereby causing inconvenience to the user
when drinking the beverage in the filmed cup. Besides, a paper cup
is formed by cutting a paper stuff. After the mold of the paper cup
is removed from the paper stuff, the residual edges and the curled
edges of the paper stuff are thrown away or recycled, thereby
wasting the material.
BRIEF SUMMARY OF THE INVENTION
[0003] The primary objective of the present invention is to provide
an integrally formed paper straw with a pointed head.
[0004] In accordance with one embodiment of the present invention,
there is provided a pointed paper straw comprising a paper straw
which is integrally formed with a pointed head. The paper straw is
formed by a paper mold sheet. The paper mold sheet is formed by a
residual edge of a paper material. The residual edge has an end
formed with a pointed portion. The end of the residual edge has a
left side and a right side that are cut symmetrically, with two
triangular pieces being removed, to form the paper mold sheet which
includes the pointed portion. The paper mold sheet has a left side
and a right side that are curled inward and are overlapped and
connected to form an overlapping portion. The overlapping portion
is stuck to form the paper straw. The paper straw includes the
overlapping portion and the pointed head.
[0005] Preferably, the overlapping portion of the paper straw is
stuck by a high frequency.
[0006] Preferably, the residual edge of the paper material is made
of coated paper.
[0007] In accordance with another embodiment of the present
invention, there is provided a pointed paper straw comprising a
paper straw which is integrally formed with a pointed head. The
paper straw is formed by a paper mold sheet. The paper mold sheet
is formed by a paper material. The paper material has an end formed
with a pointed portion. The end of the paper material has a left
side and a right side that are cut symmetrically, with two
triangular pieces being removed, to form the paper mold sheet which
includes the pointed portion. The paper mold sheet has a left side
and a right side that are curled inward and are overlapped and
connected to form an overlapping portion. The overlapping portion
is stuck to form the paper straw. The paper straw includes the
overlapping portion and the pointed head.
[0008] Preferably, the paper material is made of coated paper.
[0009] According to the primary advantage of the present invention,
the recycled paper is worked simply and integrally formed with the
paper straw which includes the pointed head, so that the paper
straw is produced easily and quickly, thereby greatly reducing the
cost of fabrication.
[0010] According to another advantage of the present invention, the
paper straw is made of recycled paper and does not contain any
plastics or glue so that the paper straw can be recycled completely
to achieve the purpose of environment protection.
[0011] According to a further advantage of the present invention,
the paper straw is integrally formed with the pointed head without
needing a secondary working procedure.
[0012] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0018] Referring to the drawings and initially to FIG. 1, a paper
material 2 includes a plurality of container sheet molds 21 and a
plurality of residual edges 22. Each of the container sheet molds
21 is a model of a container and may be cut to have the shape of
the container. When the container sheet molds 21 are set, the
residual edges 22 are kept on the paper material 2. After the
container sheet molds 21 are cut, the residual edges 22 and the
curled edges of the paper material 2 are recycled. Thus, the
residual edges 22 and the curled edges of the paper material 2 are
used to make a paper straw 20 as shown in FIG. 4. Preferably, the
residual edges 22 and the curled edges of the paper material 2 are
made of coated paper.
[0019] Referring to FIGS. 2 and 3, each of the residual edges 22
has an end formed with a pointed portion 2201. The end of each of
the residual edges 22 has a left side and a right side that are cut
symmetrically, with two triangular pieces 221 being removed, to
form a paper mold sheet 220 with the pointed portion 2201 as shown
in FIG. 3. Each of the two triangular pieces 221 forms a slope on
the end of each of the residual edges 22.
[0020] Alternatively, the paper material 2 as shown in FIG. 1 is
directly cut to remove the two triangular pieces 221, so as to form
the paper mold sheet 220 with the pointed portion 2201. Thus, it is
unnecessary to collect the residual edges 22 so that the paper mold
sheet 220 satisfies the requirement of mass production.
[0021] Referring to FIGS. 3 and 4, the paper mold sheet 220 has a
left side and a right side that are curled inward and are
overlapped and connected to form an overlapping portion 201.
Preferably, the overlapping portion 201 is hot pressed and stuck by
a high frequency. Thus, the paper mold sheet 220 is made into a
paper straw 20 which is integrally formed with a pointed head
202.
[0022] Accordingly, the paper straw 20 is made of recycled paper,
such as the residual edges 22 or the curled edges of the paper
material 2, thereby greatly reducing the cost of fabrication, and
thereby achieving the purpose of environment protection. In
addition, the overlapping portion 201 of the paper straw 20 is hot
pressed by a high frequency, so that the paper straw 20 does not
contain any plastics or glue and can be recycled completely to
provide an environment friendly function.
[0023] Referring to FIG. 5, the paper straw 20 includes the pointed
head 202 that easily pierces the plastic film 30 of a cup 3,
thereby facilitating the user drinking the beverage contained in
the cup 3.
[0024] In conclusion, the recycled paper is worked simply and
integrally formed with the paper straw 20 which includes the
pointed head 202, so that the paper straw 20 is produced easily and
quickly, thereby greatly reducing the cost of fabrication. In
addition, the paper straw 20 is made of recycled paper and does not
contain any plastics or glue so that the paper straw 20 can be
recycled completely to achieve the purpose of environment
protection. Further, the paper straw 20 is integrally formed with
the pointed head 202 without needing a secondary working
procedure.
[0025] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the scope
of the invention.
