Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to An improvement of a nozzle
structure, especialy to an integrally formed nozzle structure with
soft and hard plastics, which comprises a soft type mouth piece
made of soft plastic material. A flexible supporting frame made of
hard plastic material is integrally provided inside of the mouth
piece, so that when the user may hold the mouth piece in his/her
mouth to drink water, he/she may have the soft feeling on the mouth
piece and effectively stop the water flow with the press from the
hard plastic supporting frame and its flexible clipping rods.
Besides, an awal-shaped block and an periphal groove are provided
on the water outlet such that when the water outlet may wholly open
is pressed, so that when the water outlet can fully expanded when
being pressed. Unlike those prior arts, the present may allow great
amount of water to flow out of the container.
[0003] (b) Description of the Prior Arts
[0004] People usually need to replenish lost water due to sweat in
taking outdoor exercises such as jogging, mountain climbing, or
cycling. As an exerciser cannot easily obtain water as at home,
he/she generally would prepare a special water pouch for carrying
water or drink for the need supplementing water in exercise. Said
water pouch may be carried on the back of the exerciser and would
not hinder the exerciser from exercising.
[0005] As the special water pouch for outdoor exercises uses a
conduit to draw water for the user's sucking, it has a nozzle
structure on the water pouch. In soft nozzle structure as disclosed
in the U.S. Pat. Nos. 5,601,207, 5,730,336, 5,791,510, 6,032,831,
and 6,070,767, the outer appearance of the nozzle is similar to a
nipple of a feeding bottle, which is made by injection of soft
plastic material such as PU or silicone. The front end of the
nozzle has a plat or cross shape water outlet crevice. The
peripheral plastic board of the tiny outlet crevice normally has a
natural elasticity so that when the side walls of the water outlet
crevice are pressed, the peripheral plastic board would close and
stop the water flow.
[0006] When in use, the user holds the soft nozzle in the mouth and
clenches by teeth and lips so as to press the water outlet crevice
to be in open status. Operating along with suction by mouth, the
user can drink the water in the pouch.
[0007] Although soft nozzle of this type makes sucking easier
without requiring much effort, water would leak from the nozzle
simply due to accidental squeeze which makes the lips of the nozzle
turn outside. FIG. 1 shows a sectional view of the nozzle A
according to U.S. Pat. No. 6,032,831, wherein the heightened lips B
are provided on two sides of the water outlet C, so as to obtain
better function of stopping water by the high elasticity of the
boards of the lips.
[0008] When the nozzle A is pressed vertically (as shown in FIGS. 2
and 3), the water outlet C is pressed by the board to turn outside
like lips. When turning to the angle L, the lips are connected with
the board on the root portion D. Therefore, the angle of the
opening is limited. As such, the water pouch of this type might not
be applicable to juice with fruit flesh. In view of the above, the
present discloses a soft type nozzle with greater opening.
BRIEF DESCRIPTION OF THE INVENTION
[0009] The primary object of the present invention is to provide a
nozzle enabling the user to have a soft and comfortable feeling for
holding it in the mouth, and in the meantime to obtain a better
anti-leaking effect of the soft nozzle. Besides, when being pressed
on the water outlet, the opening of the nozzle can greatly
expanded.
[0010] To obtain the above-mentioned object, the present invention
comprises a soft covering plastic materials and a hard supporting
frame. A combining frame is provided on the hard supporting frame.
Clipping rods covered by soft plastic material made integrally to
be a nozzle are extended symmetrically on the combining frame, so
as to provide in the center of the nozzle the function of stopping
water. Meanwhile, a taper board and a peripheral groove are
provided in the center of the nozzle, wherein a water outlet
crevice is provided in the center of the taper board so that when
the water outlet is being pressed, it can fully open.
[0011] The foregoing object and summary provide only a brief
introduction to the present invention. To completely appreciate
these and other objects of the present invention as well as the
invention itself, all of which will become apparent to those
skilled in the art, the following detailed description of the

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] For the purpose of promoting an understanding of the
principles of the invention, reference will now be made to the
embodiment illustrated in the drawings. Specific language will be
used to describe the same. It will, nevertheless, be understood
that no limitation of the scope of the invention is thereby
intended, alterations and further modifications in the illustrated
device, and further applications of the principles of the invention
as illustrated herein being contemplated as would normally occur to
one skilled in the art to which the invention relates.
[0026] As shown in FIGS. 4.about.6, the nozzle 10 according to the
present invention comprises a hard plastic supporting frame 11 and
a coating layer 12 of soft plastic material.
[0027] The supporging frame 11 made by the injection of hard
plastic material comprises an integral frame 13, a threaded
fastening ring 14 and two symmetrical clipping rods 12. An opening
13 is provided in the center of the supporting frame. The extended
ends of the clipping rods 12 separate, and positioning pillars 17
are protruded from the external side of each clipping rod.
[0028] When the supporting frame 11 is placed in the mold, the
positioning pillars 15 disposed on the outer side of the clipping
rod acts as the positioning of the mold, and a propping mold in the
mold can be retractable to insert into the opening 16 such that the
board press against the inclined pressing section 18 of the
clipping rods 15. The two clipping rods 15 are squeezed to open at
a tiny angle. After the propping mold props and opens the two
clipping rods 15, the soft plastic material is injected into the
mold so that the exterior of the supporting frame 11 is completely
wrapped by the soft plastic material which forms a soft coating
layer 12 to comfort the user's mouth contact during sucking.
[0029] After removing the propping mold, the two hard plastic
clipping rods 15 are pressed to separate and in an open status. As
the propping mold is removed, it naturally forms a resuming status
and retracts the clipping stress a (as shown in FIG. 6). The
elasticity coefficient of the soft plastic coating layer 20 around
the periphery of the supporting frame is smaller than the retracted
clipping stress a on the clipping rods, so that an excellent
clipping force forms and naturally provides an excellent
anti-leaking effect when the water outlet crevice 19 at the center
of the front section of the nozzle 10 is closed.
[0030] As the layer of soft plastic 12 is formed, it is combined
with a thickened board 20 which is in taper shape. A peripheral
groove 21 is provided on the roots of the taper board 20, so that a
water outlet crevice 19 is formed in the center of the board. When
the water outlet crevice 19 of the nozzle 10 is being pressed, it
can fully open.
[0031] Now referring to FIGS. 7 and 8 for the soft type nozzle 10
according the invention. When the nozzle 10 is hold by the lips 30
of the user, and subsequently clenched by the teeth 31, the soft
layer 12 of the nozzle transforms (as indicated by arrow E), and
the lips 22 separate to a distance M and to expand the water outlet
crevice 19 (as shown in FIG. 9) to be in an open status for the
fruit flesh in the juice to pass through the outlet.
[0032] As shown in FIG. 9, when the user holds the nozzle 10 by
mouth, the user can hold the soft coating layer 12 of the nozzle by
an appropriate force exerted by the upper and lower jaws. The
nozzle according to the present invention has a layer of soft
plastic material on the upper and the lower sides of the nozzle 10,
so that when the soft coating layer 12 is hold in the mouth, the
user enjoys the comfort of sucking the water the same way as that
from general soft nozzle. Comparing with the convenional nozzle
shown in FIG. 3, as the present invention is provided on the root
periphery of the taper board 20 a peripheral groove 21 with a thin
board, when the lips 22 of the taper board 20 turn outside, the
border (as indicated by arrow E) between the two lips 22 extends
laterally due to the different elasticility and transformation of
the boards. As such, the water outlet crevice 19 expands and allow
the water/juice to flow out.
[0033] When the holding force is released, the left and right sides
of the clipping rods will automatically clip to dose the water
outlet crevice 19 in order to attain a definite anti-leaking effect
which is much better than that for the traditional soft nozzle.
[0034] As shown in FIG. 10, the nozzle 10 according to the
invention can be applicable to a water pouch 50 for biking. The
user may carry the water pouch on his/her back and drink the water
through the nozzle 10 by a conduit 51 connected to the water
pouch.
[0035] As shown in FIGS. 11 and 12, the nozzle 10a according to the
invention may be provided with separate water outlet crevices 19a
in the front end thereof. The water outlet crevices 19a also
comprise a taper board 20 and a peripheral groove 21. When the soft
layer of plastic 12 is pressed vertically (referring to FIG. 7),
the two water outlet crevices 19a expand (as shown in FIG. 12).
[0036] Concluded above, the invention refers to an improvement of a
nozzle made integrally with soft and hard plastic materials. A hard
supporting frame is hidden inside of a layer of soft plastic. By
way of the elasticity of two clipping rods, the water/drink can
flow out of the water pouch for the user's drinking and for
stopping water flow after used. A taper board and a peripheral
groove are provided on the water outlet crevice, so that when the
board is being pressed, the water flow may be enhanced, which is
especially applicable to juice with fruit flesh.
[0037] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0038] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
