Description
[0001] The present invention relates to a liquid pouring member and a container.
[0002] A generally employed container has a nozzle attached to a plug fitted to an opening
of a container that contains liquid such as liquid medicine so as to be poured to the diseased
part. After pouring the liquid, the nozzle is capped. There may be the case that when
removing the cap for the subsequent use of the container, the liquid remaining on the inner
wall surface of the nozzle is extruded under the internal pressure higher than the external
pressure, causing accidental sprouting from the nozzle.
[0003] PTL 1 discloses the technique for solving the above-described problem. Referring
to Fig. 1 of PTL 1, the plug fitted to the disclosed squeeze container includes a mount fitting
cylinder 3 to be internally fitted to the neck portion 2 of the container 1, a straight cylindrical
nozzle 5 disposed while projecting from the mount fitting cylinder 3 substantially vertically
upward, and an outlet hole 4 penetrating through the nozzle 5. The lower end of the nozzle
is formed as an inclined plane marked by substantially T-like symbol.
[0004] Each of the nozzle 5 and the outlet hole 4 of the plug in the description of PTL 1 is
substantially vertically thin and long shaped. Although the liquid adheres to the inner wall
surface of the outlet hole 4 as foam when pouring the liquid, external air flowing into the
container 1 through the outlet hole 4 after pouring the liquid forces the foam to fall down to
the lower end of the nozzle 5. At this time, the foam falling down to the lower end of the
nozzle 5 easily drops into the container 1 along the inclined plane marked by substantially
T-like symbol of the lower end of the nozzle 5. This may prevent the liquid that has
adhered to the inner wall surface of the outlet hole 4 and the nozzle 5 from being kept
remained. Accordingly, the remaining foam-like liquid is never extruded from the outlet
hole 4 when removing the cap 8 in the subsequent pouring.
[0005] If the liquid remains on the inner wall surface of the mount fitting cylinder 3 (skirt), and in the gap between the inner wall of the skirt 3 and the lower end of the nozzle 5, the
remaining liquid may infiltrate into the outlet hole 4 by the capillarity. The disclosed
technique as PTL 1 may fail to prevent spouting of the infiltrated liquid under the internal
pressure upon removal of the cap 8.
[0006] PTL 1: Japanese Utility Model Laid-Open No. 2-48561
[0007] The present invention has been made in consideration of the above-described circumstances, and it is an object of the present invention to provide a liquid pouring member
and a container, capable of effectively preventing the liquid from spouting upon opening.
[0008] For the purpose of solving the above-described problem, the present invention provides a liquid pouring member that includes a nozzle, a base to be engaged with an
opening of a container, and a hollow cylindrical skirt extending from the base to be fitted into
the opening of the container. The nozzle includes a nozzle upper part that extends from an
upper surface of the base opposite the skirt, and includes an outlet port for pouring a liquid
content from the container, a nozzle lower part that is formed in a radial inner side of the skirt
while extending from a lower surface of the base, and includes an inlet port through which the liquid content flows from the container, and an inner passage formed from the inlet port
to the outlet port while passing through the nozzle lower part and the nozzle upper part. The
nozzle lower part includes an end portion with an inclined surface in which the inlet port is
formed. The end portion has at least a part protruding from the skirt. A constriction is
formed inside the inner passage of the nozzle lower part. The nozzle lower part and the
skirt are configured to form a relatively radially wide portion and a relatively radially narrow portion between the nozzle lower part and an inner wall of the skirt adjacent to the nozzle lower part.
[0009] Preferably, the nozzle lower part includes a column portion vertically extending
from the lower surface of the base, and the column portion includes a side surface and a
bottom surface from which the end portion extends. In this case, more preferably, the bottom surface has the same height as an edge of the skirt.
[0010] More preferably, the constriction is formed from a position at the same height as the bottom surface to an inner side of the column portion.
[0011] More preferably, an edge portion as an intersection between the side surface and the bottom surface forms an angular portion at an angle of 90.
[0012] The end portion may include a convex portion axially extending along aside surface
of the radially narrow portion for guiding falling droplets. Preferably, the convex portion radially protrudes in a range not in excess of a diameter of the column portion.
[0013] The nozzle lower part according to another preferred embodiment has no stepped
portion, and extends up to the end portion.
[0014] In the present invention, the structure having the radially wide and narrow portions
may be formed by the means (1) to (3) to be described below, for example.
(1) The nozzle lower part extends from a position on the lower surface of the base, biased from a center of the skirt to form the radially wide and narrow portions. At this time, the nozzle upper part may extend from a biased position on the upper surface of the base in
alignment with the nozzle lower part. Alternatively, only the nozzle lower part is biasedly positioned from the center of the skirt, and the nozzle upper part may extend concentrically
with the skirt.
(2) The skirt further includes a partial inner circumferential wall that partially surrounds
the nozzle lower part in a radial inner side of an outer circumferential wall of the skirt. The
radially narrow portion is formed between the nozzle lower part and the partial inner
circumferential wall adjacent to the nozzle lower part. The radially wide portion is formed between the nozzle lower part and the inner wall of the skirt adjacent to the nozzle lower part in a region where the partial inner circumferential wall is not formed.
(3) The nozzle lower part includes a portion with relatively large thickness, and a
portion with relatively small thickness of an outer circumference of the inner passage. The
radially narrow portion is formed between the portion with large thickness and the inner wall
of the skirt, and the radially wide portion is formed between the portion with small thickness and the inner wall of the skirt.
[0015] Preferably, a length of the inner passage from the constriction to the outlet port is equal to or longer than 5 mm.
[0016] Concerning the structure for fitting the member according to the present invention to the container, the base includes a top having the upper surface and the lower surface, and a
side surface extending downward from the top. A thread may be formed on an inner wall of the side surface for threaded engagement with a thread formed over an outer circumference
of a side surface of the opening of the container. In this embodiment, a cap for closing the outlet port by covering at least the nozzle upper part may be provided. In this case, a thread
is formed on an inner wall of the cap, and a thread is formed over an outer circumference of the side surface of the nozzle upper part for threaded engagement with the thread of the cap.
[0017] Concerning another structure for fitting the member according to the present
invention to the container, the base may be a plate-like member including the upper surface
and the lower surface. In this case, the plate-like member is engaged with a top end portion
of the opening of the container to lock further entry of the inner plug into the container. In
this embodiment, a cap for closing the outlet port by covering at least the nozzle upper part
may be provided. In this case, a thread is formed on an inner wall of the cap for threaded
engagement with a thread formed over an outer circumference of the side surface of the
opening of the container.
[0018] According to a preferable embodiment of the present invention, as the capped
member, an upper cap for closing the outlet port by covering at least the nozzle upper part
may be provided. The base is a lower cap to be fitted to the opening of the container, and the upper cap is pivotally connected to the lower cap to allow opening and closing.
Preferably, the upper cap is configured to be engaged with the lower cap in a snap-fit manner
when the upper cap is closed.
[0019] More preferably, the cap or the upper cap according to the respective embodiments
includes a protrusion to be inserted into the outlet port when the cap or the upper cap is
closed.
[0020] Concerning the member according to the respective embodiments, preferably, the
nozzle upper part includes a liquid drip-off portion formed over an outer circumference of an
end portion of the nozzle upper part.
[0021] The inclined surface of the end portion of the nozzle lower part maybe directed to
either the wide portion or the narrow portion.

[0023] The embodiments according to the present invention will be described below
referring to the drawings.
(First Embodiment)
Figs. 1(a) to 1(d) show an inner plug 1 as a liquid pouring member according to a
first embodiment of the present invention. The inner plug 1 fitted to a container that
contains the liquid content such as the liquid medicine is a member that allows pouring of the
liquid content as described below. The inner plug 1 may be produced into an integral part
through the injection molding process. However, it maybe arbitrarily produced without being limited to the above-described process.
[0024] As Fig. 1(c) shows, the inner plug 1 includes a nozzle 2, abase 3 to be engaged with
an opening of the container (not shown), and a hollow cylindrical skirt 4 extending from the
base 3 for fitting to the inner opening of the container. The nozzle 2 includes a nozzle upper
part 5 (Fig. 1(b)) extending from an upper surface 16 of the base 3 in a direction opposite the skirt 4, and a nozzle lower part 6 extending from a lower surface 17 of the base 3. The
nozzle upper part 5 includes an outlet port 7 for pouring the liquid content from the container.
The nozzle lower part 6 includes an inlet port 8 into which the liquid content flows from the
container. An inner passage 9 is formed from the inlet port 8 to the outlet port 7 while penetrating through the nozzle lower part 6 and the nozzle upper part 5.
[0025] Referring further to Fig. 1(c), the nozzle lower part 6 is formed in the radial inner
side of the skirt 4, and includes an end portion 11 with an inclined surface 12. The inlet port
8 is formed in the inclined surface 12. The nozzle lower part 6 includes a column portion
vertically extending from the lower surface 17 of the base 3. The column portion
includes aside surface 24 and a bottom surface 25. An edge portion between the side
surface 24 and the bottom surface 25 forms an angular portion 13 at an angle of 90.
Preferably, the bottom surface 25 has the same height as an edge of the skirt 4, and has the
end portion 11 extending therefrom. In this case, the end portion 11 protrudes from the skirt
4. The inner passage 9 includes a constriction 20 with its sectional area of a passage smaller than that of the other part. Preferably, the constriction 20 is formed at the lower position closer to the end portion 11. More preferably, the constriction 20 is formed into the column portion 10 from the position at the same height as the bottom surface 25. Preferablythe length of the inner passage 9 between the constriction 20 and the outlet port 7 is as long as possible, for example, equal to or longer than 5 mm, and more preferably, equal to or longer than 10 mm.
[0026] Referring to Fig. 1(d), in the embodiment, the nozzle lower part 6 extends
downward from the position on the lower surface 17 biased from the center of the skirt 4,
thus forming a radially wide portion 22 and a radially narrow portion 23. In the
embodiment, as Fig. 1(a) shows, the nozzle upper part 5 also extends from the biased position on the upper surface 16 of the base 3 in alignment with the nozzle lower part 6. As shown in the drawing, the inclined surface 12 of the end portion 11 of the nozzle lower part 6 is
directed to the wide portion 22. However, the inclined surface 12 may be directed to the narrow portion 23, for example, or arbitrarily directed without the present invention being limited to the one as described above (applicable to the other embodiment).
[0027] Referring to Fig. 1(c), the base 3 includes a top 14 having the upper surface 16 and
the lower surface 17, and a side surface 15 extending downward from the top 14. A thread 18 is formed on an inner wall of the side surface 15 for threaded engagement with a thread
formed over an outer circumference of a side surface of the opening of the container. As
Fig. 1(b) shows, a thread 19 is formed over an outer circumference of the side surface of the
nozzle upper part 5. A liquid drip-off portion 21 is formed over the outer circumference of
an end portion of the nozzle upper part 5.
[0028] Fig. 2 shows a cap 30 for covering the nozzle upperpart 5 of the innerplug 1 as
shown in Fig. 1. Referring especially to Fig. 2(c), a thread 31 is formed on an inner wall of
the cap 30. A protrusion 33 is formed on a back surface of a top plate 32 of the cap 30.
[0029] Fig. 3 shows a state in which the inner plug 1 as shown in Fig. 1 is fitted to a
container 40, and the cap 30 as shown in Fig. 2 covers the inner plug 1. Referring
especially to Fig. 3(c), a thread 42 is formed over an outer circumference of the side surface
of an opening 41 of the container 40. The thread 18 of the inner plug 1 is threadedly engaged with the thread 42 of the container so that the skirt 4 of the inner plug 1 is fitted to the inside of the open space of the opening 41 of the container 40. Accordingly, the inner plug 1 may be fitted to the container 40.
[0030] Threadedly engaging the thread 31 of the cap 30 with the thread 19 of the nozzle
upper part 5 allows attachment of the cap 30 to the inner plug 1. At this time, the protrusion
33 of the cap 30 is inserted into the outlet port 7 of the nozzle 2. Accordingly, there is no
risk that the liquid content of the container 40 leaks outside while the cap 30 is attached to the inner plug 1. Furthermore, air-tightness in the container may be retained.
[0031] Functions of the inner plug 1 according to the first embodiment will be described referring to Figs. 4 and 5.
[0032] Referring to Fig. 4, the inner plug 1 is fitted to the container 40 as shown in Fig. 3 that contains a liquid content 43 such as the liquid medicine, and is covered with the cap 30.
The container is then laid sideways as shown in the state (1) first. In the state (1) in which
the container is laid sideways, the liquid content 43 flows into the inlet port 8, and passes
through the constriction 20 by the capillarity. As the outlet port 7 is closed with the
protrusion 33 of the cap 30, air remains in the inner passage 9. Because of the resultant air
pressure, the liquid content 44 that has reached the constriction 20 remains in the inner
passage near the constriction 20 and the inlet port 8.
[0033] As the state (1) in which the container is laid sideways is brought into the upright
posture as indicated by the state (2), the liquid content that has gathered around the inner plug
1 in the state (1) in which the container is laid sideways cannot sustain its own weight, and
falls down. Some amount of the liquid content is kept adhering to the inner wall of the
inner plug 1 under the surface tension. Referring to Fig. 5, among the liquid content
gathered between the nozzle lower part 6 and the inner wall of the skirt 4, the liquid content
gathered in the radially wide portion 22 moves toward the narrow portion 23 under the
capillary attraction. (see arrow marks of Fig. 5). Referring back to Fig. 4, it is shown that
the liquid content 45 that has moved toward the narrow portion 23 and gathered cannot
sustain its own weight, thus falling down. The end portion 11 having the inlet port
8 protrudes downward farther than the edge of the skirt 4. Furthermore, as the angular
portion 13 at an angle of 90 is formed, the liquid content to be gathered around the inlet port 8 under the capillary attraction may be minimized.
[0034] Referring to Fig. 4, detachment of the cap 30 from the container in the state (2)
brings the container into the state (3) in which the outlet port 7 is released. As a result, an
action for venting expansion force of air remaining in the container works. The internal
pressure of the container acts to equalize the outside pressure so that the liquid content
gathered around the constriction 20 is forced out to move upward through the inner passage 9 as indicated by a reference numeral 46 in the state (3).
[0035] Upon passage of a short time in transition from the state (3) to the state (4), the
extruded liquid content splashes before reaching the outlet port 7 while passing through the
long inner passage 9 as indicated by a reference numeral 47. Then air in the container is
communicated with outside air to bring the pressure into the ordinary state. The liquid
content gathered in the radially narrow portion 23 falls down by its own weight. Even if a
small amount of the liquid content remains, the remaining liquid is reduced from the portion
around the inlet port 8 upon removal of the cap 30 because of the end portion 11 having the inlet port 8 protruding downward farther than the edge of the skirt 4, and the angular portion
13 at an angle of 900. This makes it possible to effectively prevent spouting of the
remaining liquid upon removal of the cap.
[0036] As described above, the embodiment prevents the liquid content from spouting as a
result of detaching the cap 30.
[0037] The liquid content to be contained in the container 40 includes materials for dental
use, for example, the dental adhesive material such as a dental bonding material, the
pretreatment agent for dental use such as the dental primer, the denture-base material such as
the instantaneous polymerized resin and lining material, the dental lubricant, the dental
etching agent, the dental cleaning material, and the medicines for dental use, the medical
adhesive, the medicine, industrial adhesive, and medicine. However, arbitrary materials may be contained in the container without the invention being limited to those described above.
[0038] (Second Embodiment)
In the first embodiment, the nozzle 2 is entirely biased from the center of the base 3 and the skirt 4 to form the radially wide portion 22 and the radially narrow portion 23. In
the second embodiment according to the present invention, another means is used for forming
the radially wide and narrow portions without the invention being limited to the example as
described above.
[0039] Fig. 6 shows an inner plug lb according to the second embodiment of the present invention. Referring to Fig. 6, no reference numerals are used for designating the similar
components to those of the first embodiment, or the same reference numerals suffixed by "b"
may be used. The detailed explanation of those components, thus will be omitted.
[0040] As Figs. 6(a), 6(b), 6(c), and 6(d) show, a nozzle 2b is entirely formed
concentrically with a base 3b. That is, a nozzle upper part 5b and a nozzle lower part 6b are
formed concentrically with a skirt 4b, and not biased unlike the first embodiment.
[0041] As Figs. 6(c) and 6(d) show, the skirt 4b further includes a partial inner
circumferential wall 50 that partially surrounds the nozzle lower part 6b in the radial inner side of the outer circumferential wall of the skirt 4b. As a result, a radially narrow portion
23b is formed between the nozzle lower part 6b and the partial inner circumferential wall
adjacent to the nozzle lower part 6b, and a radially wide portion 22b is formed between
the nozzle lower part 6b and the inner wall of the skirt 4b adjacent to the nozzle lower part 6b
in a region where the partial inner circumferential wall 50 is not formed.
[0042] The second embodiment may provide the similar effects and advantages to those
derived from the first embodiment.
[0043] (Third Embodiment)
A third embodiment includes means for further improving the function of the first
embodiment in which the liquid content 45 that has been moved to the narrow portion 23, and gathered with time cannot sustain its own weight, and falls down as shown in the state (2) of Fig. 4.
[0044] Fig. 7 shows an inner plug le according to the third embodiment. ReferringtoFig.
7, no reference numerals are used for designating the similar components to those of the first embodiment, or the same reference numerals suffixed by "c" may be used. The detailed
explanation of those components, thus will be omitted.
[0045] As Figs. 7(c) and 7(d) show, an end portion 1c has a convex portion 51 for guiding
falling droplets, axially extending along the side surface of a radially narrow portion 23c.
The convex portion 51 radially protrudes in a range not in excess of the diameter of a column
portion 10c.
[0046] According to the third embodiment, the liquid content that has moved to the narrow
portion 23c, and gathered with time cannot sustain its own weight, and falls down when
bringing the container 40 into the upright posture as indicated by the state (2) of Fig. 4 and
Fig. 5. As the convex portion 51 serves to guide the falling droplets, it is possible to reduce
the remaining liquid more effectively.
[0047] Fig. 7 shows an example having the convex portion 51 for guiding the falling
droplets added to the structure of the first embodiment. This applies to the second
embodiment as described above, and the fourth to sixth embodiments to be described later.
[0048] (Fourth Embodiment)
In the first embodiment, the nozzle 2 is entirely biased from the center of the base
3 and the skirt 4 to form the radially wide portion 22 and the radially narrow portion 23. A
fourth embodiment of the present invention corresponds to a modified example of the first
embodiment.
[0049] Fig. 8 shows an inner plug Id according to the fourth embodiment of the present
invention. Referring to Fig. 8, no reference numerals are used for designating the similar
components to those of the first embodiment, or the same reference numerals suffixed by "d"
may be used. The detailed explanation of those components, thus will be omitted.
[0050] As Figs. 8(a), 8(b), and 8(c) show, a nozzle upper part 5d of the fourth embodiment
is formed concentrically with a base 3d and a skirt 4d.
[0051] As Figs. 8(c) and 8(d) show, likewise the first embodiment, a nozzle lower part 6d
extends from a position on a lower surface 17d of the base 3d, biased from the center of the
skirt 4d to form a radially wide portion 22d and a radially narrow portion 23d between the
nozzle lower part 6d and an inner wall of the skirt 4d adjacent to the nozzle lower part 6d.
[0052] As described above, in the fourth embodiment, the nozzle upper part 5d and the
nozzle lower part 6d are not aligned with each other, an inner passage 9d has a part that is bent in the nozzle lower part 6d as shown in Fig. 8(c). The effects and advantages similar to
those of the first embodiment may be derived from the fourth embodiment. As the nozzle
upper part 5d is positioned at the center of the inner plug 1d, the cap may have the same axial
center as that of the container.
[0053] (Fifth Embodiment)
In the first and the fourth embodiments, at least the nozzle lower part is biased from
the center of the skirt to form the radially wide and narrow portions. In the second
embodiment, the partial inner circumferential wall 50 is provided to form the radially wide
and narrow portions. The present invention is not limited to the above-described examples.
In a fifth embodiment according to the present invention, another means is provided to form the radially wide and narrow portions. In an example according to the fifth embodiment, the cap is differently shaped.
[0054] Fig. 9 shows an inner plug le according to the fifth embodiment of the present
invention. Referring to Fig. 9, no reference numerals are used for designating the similar
components to those of the first embodiment, or the same reference numerals suffixed by "e" may be used. The detailed explanation of those components, thus will be omitted.
[0055] As Figs. 9(a) to 9(d) show, a nozzle 2e according to the fifth embodiment is entirely
formed substantially concentrically with a base 3e. That is, a nozzle upper part 5e and an
end portion 11 e of a nozzle lower part 6e are formed concentrically with a skirt 4e, and not
biased unlike the first embodiment.
[0056] As Figs. 9(c) to 9(e) show, an outer circumference (column portion 10e) in an inner
passage 9e of the nozzle lower part 6e has a relatively thick portion 52, and a relatively thin
portion 53. A radially narrow portion 23e is formed between the thick portion 52 and the
inner wall of the skirt 4e, and a radially wide portion 22e is formed between the thin portion
53 and the inner wall of the skirt 4e.
[0057] The effects and advantages similar to those of the first embodiment may be derived
from the fifth embodiment.
[0058] As Figs. 9(b) and 9(c) show, the base 3e of the inner plug le according to the fifth
embodiment is a plate-like member 14e having an upper surface 16e and a lower surface 17e.
As Fig. 9(d) shows, the plate-like member 14e is engaged with a top end portion of the
opening 41 of the container 40 to lock further entry of the inner plug le into the container 40.
[0059] The nozzle upper part 5e according to the fifth embodiment has no thread to be
threadedly engaged with the thread of the cap, but is adaptable to a cap 30e (Fig. 9(d))
different from the cap 30 as shown in Fig. 2. The cap 30e has a thread 54 on its inner wall.
The thread 54 is threadedly engaged with the thread 42 formed over the outer circumference
of the side surface of the opening 41 of the container 40 to allow the cap 30e to be attached to
the container 40 to which the inner plug leis fitted. At this time, a protrusion 33e of the
cap 30e may be fitted to an outlet port 7e of the nozzle.
[0060] The fitting structure of the inner plug le, and the structure of the cap 30e according
to the fifth embodiment are applicable to the respective embodiments described above so
long as they are structurally configurable. For example, the fitting structure and the cap 30e
as shown in Fig. 9(d) are easily applicable to the embodiment, for example, having the nozzle
upper part not biased from the center of the skirt.
[0061] (Sixth Embodiment)
As the cap for the inner plug of the respective embodiments according to the present
invention, the cap 30 as shown in Fig. 2, and the cap 30e as shown in Fig. 9(d) have been
described. A sixth embodiment will provide a cap differently structured from those as
described in the embodiments.
[0062] Fig. 10 shows a hinged cap If according to the sixth embodiment of the present
invention in an opened state. Fig. I Ishows that the hinged cap if is in a closed state.
[0063] Referring to Fig. 10, especially to Figs. 10(c) and 10(f), a lower cap 3f of the hinged
cap if includes a hinge support portion 64, and a locking portion 65 formed at a side counter
to the hinge support portion 64. An upper cap 60 is pivotally connected to the hinge support
portion64 via ahinge 61f and a spring 69. A lever 62 elastically pivoting about a fulcrum
68 is disposed above the upper cap 60. A hook 63 is formed at an end portion of the lever
62. As Figs. 10(a) and 10(f) show, a protrusion 66 is formed on a back surface of a top
plate of the upper cap 60. A guard 67 is formed around the protrusion 66.
[0064] As Fig. 11(b) to1 l(d), and 11(f) show, when pivotally moving the upper cap
toward the nozzle upper part 5f, both edges of the upper cap 60 and the lower cap 3f are
tightly engaged to close the hinged cap If. Atthis moment, the hook 63 of the lever 62 is
engaged with the locking portion 65 of the lower cap 3f in a snap-fit manner for locking so
that the upper cap 60 is not carelessly opened. For opening the upper cap 60, the upper
portion (at the side of a finger catcher) of the lever 62 is pressed toward the axial center to
easily release the engagement between the hook 63 and the locking portion 65 so that the upper cap 60 is opened. As Fig. 11(f) shows, when the upper cap 60 is closed, the
protrusion 66 is inserted into an outlet port 7f of the nozzle upper part 5f. This may prevent
the liquid content in the container from leaking out in the closed state of the upper cap 60,
and retain air-tightness in the container. The nozzle upper part has a liquid drip-off portion
21f formed thereon. As Figs. 10(a) and 10(f) show, the upper cap 60 has a portion with
further reduction in thickness, that is, a thinned portion 70f.
[0065] The structure of the nozzle has been described in the sixth embodiment, taking the
first embodiment as the example. It is also possible to apply the structure of the nozzle
according to any one of the second to the fourth embodiments to the sixth embodiment.
[0066] (Seventh Embodiment)
A seventh embodiment is a modified example of the hinged cap according to the
sixth embodiment. The similar components to those of the sixth embodiment will be designated with the same reference numerals, and the components corresponding to the sixth embodiment will be designated with the same reference numerals suffixed by "g". The detailed description will be made with respect only to the feature different from the sixth embodiment.
[0067] Fig. 12 shows a hinged cap lg according to a seventh embodiment of the present
invention in an opened state.
[0068] As Fig. 12(a) shows, a hinge 61g according to the seventh embodiment has its
strength enhanced by increasing its width larger than that of the hinge 61f according to the
sixth embodiment. As Figs. 12(a) and 12(f) show, a thinned portion 70g of the upper cap
is larger than the thinned portion 70f according to the sixth embodiment. Accordingly, a
lower cap 3g has a thinner portion, that is, a thinned portion 71g. This makes it possible to suppress the weight increase as a result of enlarging the hinge 61g.
[0069] Likewise the first embodiment, the end portion 11f of the nozzle lower part 6f
according to the sixth embodiment extends from the bottom surface 25 of a column portion
f to form the angular portion 13. Meanwhile, a nozzle lower part 6g according to the
seventh embodiment extends straight to an end portion 11g while having no stepped portion. That is, in the seventh embodiment, components corresponding to the bottom surface 25 of
the column portion 10f, and the angular portion 13 are not formed (Feature 1). Thenozzle
lower part 6g according to the seventh embodiment allows its side surface of the portion from
the lower surface to the end portion 1Ig to be differently shaped from the column portion as
described in other embodiments.
[0070] An inclined surface 12f of the end portion 11f according to the sixth embodiment is
directed to the wide portion 22f. Meanwhile, an inclined surface 12g of the end portion 11g
according to the seventh embodiment is directed to a narrow portion 23g (Feature 2).
[0071] The respective embodiments according to the present invention have been described.
The present invention is not limited to those examples but may be arbitrarily modified. It is
possible to apply the feature of an embodiment to the other embodiment so long as it is
structurally configurable. For example, at least one of the features 1 and 2 of the nozzle structure according to the seventh embodiment may be applied to the first to the sixth embodiments. It is also possible to apply either the feature 1 or 2 to the seventh embodiment.
