Abstract
A hinge cap having a preferable appearance irrespective of opening and closing of a cap cover, to facilitate a one-hand opening manipulation, and to prevent cost increase. In the hinge cap, a cap main body has a top plate, and most of a manipulation body for transmitting pushing force for opening the cap to the inside surface of an opening/closing hinge is covered even in a state that a cap cover is opened. Therefore, the hinge cap appearance is improved and the movement of the manipulation body does not deteriorate because the contents hardly leak into the movable portion of the manipulation body.
Description
TECHNICAL FIELD
The present invention relates to a hinge cap that is used in a container such as a bottle for cosmetics.
BACKGROUND ART
As a cap that is used in a container such as a bottle for cosmetics, a hinge cap having a cap main body and a cap cover that can cover the top portion of the cap main body and is connected to the cap main body via an opening/closing hinge is now well known as exemplified by the fact that it is regarded as a prior art technique in Japanese Examined Utility Model Publication No. HEI 6-15844, for example.
Having the opening/closing hinge serving as a spring, this hinge cap is convenient in that when the cap cover is opened from a closed state by a prescribed degree the resilient force of the opening/closing hinge causes remaining opening action automatically, and that when the cap cover is closed from an open state by a prescribed degree the resilient force of the opening/closing hinge causes remaining closing action automatically. However, the amount of manipulation to be performed at the time of opening or closing is indefinite. There is inconvenience that an opening or closing attempt results in failure if a manipulation amount is insufficient.
To shut off water during closure, the engagement between the cap main body and the cap cover needs to be strong to some extent. This results in a problem that strong manipulation force is necessary at the time of opening to disengage the cap cover from the cap main body, requiring both hands eventually.
Hinge caps capable of solving the above problems are proposed in the above Japanese Examined Utility Model Publication No. HEI 6-15844, Japanese Unexamined Utility Model Publication No. HEI 7-9747/1995, etc.
In the hinge caps described in these publications, a slidable plate is provided on the top surface of the cap main body, and a tip portion of the plate is provided with a push button portion that projects outward from the closing interface between the cap main body and the cap cover.
Therefore, if the plate is slid into the hinge cap in a state that the cap cover is closed, the cap cover is pushed and opened (i.e., disengaged from the cap main body) through wedge action, and then the rear end portion of the plate pushes the opening/closing hinge from inside. In this manner, the cap cover can be opened by one hand.
In the conventional hinge caps, the plate is provided on the top surface of the cap main body. Therefore, when the cap cover is opened, the plate itself, detailed structures for supporting it when it slides, and other members are completely exposed to view, resulting in a bad appearance.
There is another problem that the contents of the container, for example, leak into the slide portion (movable portion) between the plate and the cap main body and accumulate on the plate. As a result the movement of the plate becomes worse gradually or the plate becomes prone to come off.
As an idea for solving the above problems, to provide cover as a separate member above the plate was suggested. However, this idea was not appropriate because it undesirably increases the number of parts, complicates the structure, and makes the assembling cumbersome, which lead to cost increase.
The present invention has been made in view of the above circumstances, and an object of the invention is therefore to provide a hinge cap which has a preferable appearance irrespective of opening and closing of a cap cover, facilitate a one-hand opening manipulation, and prevent cost increase.
DISCLOSURE OF THE INVENTION
To attain the above object, the present invention has taken the following measures.
That is, a hinge cap according to the invention has a cap main body, a cap cover that can cover a top portion of the cap main body and is connected to the cap main body via an opening/closing hinge, and a manipulation body that is incorporated in the cap main body so as to be used for a manipulation of opening the cap cover.
The opening/closing hinge may be integrated with the cap main body, integrated with the cap cover, or integrated with both of the cap main body and the cap cover so as to connect them.
The cap main body has a top plate capable of covering a main part of the manipulation body even in a state that the cap cover is opened, an outer circumferential wall provided along an outer circumference of the top plate, and an inner circumferential wall that is provided so as to form a circumferential space inside the outer circumferential wall and surround a contents flow path.
On the other hand, the manipulation body has a push button portion that is accommodated in the circumferential space under the top plate of the cap main body and is exposed to outside penetrating through the outer circumferential wall of the cap main body, and a pushing end for causing the cap cover to open when the push button portion is pushed.
With this configuration, most of the manipulation body (i.e., the portions excluding the push button portion) is made unseen and hence the appearance is improved.
Further, since the contents hardly leak into the movable portion between the manipulation body and the cap main body, the movement of the manipulation body is prevented from being deteriorated.
Alternatively, the manipulation body may have a pushing end that faces the opening/closing hinge squarely from inside, a push button portion that is positioned away from the opening/closing hinge and is exposed to outside of the cap main body, and a transmission rod that connects the pushing end and the push button portion in such a manner as to cause the pushing end to push the opening/closing hinge from inside when the push button portion is pushed.
The shape of the transmission rod is not restricted to specific ones. For example, the transmission rod may assume a ring shape that surrounds, and thereby clears the contents flow path provided in the cap main body or a curved rod shape that is obtained by omitting one of the two circular arc portions of the ring shape.
Such a transmission rod is made of a resilient material that enables storage of a force for pushing the opening/closing hinge during a manipulation stroke from a position where the pushing end abuts the opening/closing hinge to a position where the push button portion is pushed thereafter by a prescribed length.
With this configuration, the opening/closing hinge can be pushed all at once when the opening force has increased to a certain level, whereby the cap cover can be opened reliably. That is, an attempt to open the cap cover never fails and the operationality is increased.
Where the transmission rod is provided, pushing force that is exerted on the opening/closing hinge by the pushing end is distributed in a period from a start of pushing on the push button portion to disengagement of the cap cover form the cap main body and opening of the cap cover. As a result, no excess load acts on the opening/closing hinge, which leads to an advantage that the opening/closing hinge is prevented from being damaged.
It is preferable that the manipulation body be provided with an acting portion that abuts a proper portion of the cap cover before, at the same time as, or after the pushing end pushes the opening/closing hinge so as to transmit upward opening force to the cap cover in accordance with an increase in a pushing manipulation amount.
With this structure, an attempt to open the cap cover never fails and the manipulation of the cap is facilitated even in the case where the water shutoff effect in a state that the cap cover is closed is enhanced (i.e., in a case where strong engagement friction occurs against the cap main body).
According to a technical measure of the invention to solve the above technical problems, there is provided a hinge cap including a cap main body

BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be hereinafter described with reference to the drawings.

FIG. 7
is an exploded view of the hinge cap
1
as viewed from the back side.
As seen from each of the above drawings, the hinge cap
1
has a cap main body
2
, a cap cover
3
, an opening/closing hinge
4
, and a manipulation body
5
.
In the first embodiment, three members that are the cap main body
2
, the cap cover
3
, and the opening/closing hinge
4
are integral with each other and only the manipulation body
5
is a separate member. Each of the integral body of the cap main body
2
etc. and the manipulation body
5
may be made of a proper synthetic resin material.
The cap main body
2
has a shape of a short cylinder having a bottom and being located upside down, as a whole, so as to be attached to a mouth
8
of a container
7
such as a bottle for cosmetics.
In this shape, a top plate
10
is a top circular plate, and an outer circumferential wall
11
is a side wall that vertically downwardly extends from an outer periphery of the top plate
10
. An inner circumferential wall
12
is provided inside the outer circumferential wall
11
in such a manner that a circumferential space having a prescribed width is interposed therebetween.
The width of the circumferential space is not limited to a constant width. However, where the top plate
10
is planar and circular as in the case of the first embodiment, it is preferable, in terms of molding and combining with a container
7
, that the circumferential space have a constant width to establish a concentric circle relationship between the outer circumferential wall
11
and the inner circumferential wall
12
.
The inner circumferential wall
12
is provided with an inwardly projecting engagement nail
13
along its lower end. By engaging the engagement nail
13
with an engagement ring
14
that is provided around the mouth
8
of the container
7
, the cap main body
2
(i.e., the entire hinge cap
1
) can be attached to the container
7
.
The top plate
8
is formed with a contents output mouth
15
in a plan-view range enclosed by the inner circumferential wall
12
.
In other wards, the inner circumferential wall
12
encloses the contents flow path with the mouth
8
of the container
7
interposed therebetween.
The cap cover
3
has a shape of a reversed circular dish shape having approximately the same diameter as the diameter of the cap main body
2
which can cover the top portion of the cap main body
2
.
In the first embodiment, the output mouth
15
having a shape of a projecting pipe is provided in the top plate
10
of the cap main body
2
, and an engagement ring
17
is provided close to its projecting end. On the cap cover
3
, as a structure corresponding to the above structure, a vertically downwardly extending cylindrical mouth cap
19
is formed to be fitted with the output mouth
15
, and an inwardly projecting engagement nail
20
is formed along a lower end of the mouth cap
19
so as to correspond to the engagement ring
17
.
An alternative structure (not shown) in which the mouth cap
19
is fitted into the output mouth
15
may be employed.
Therefore, when the cap main body
2
is covered with the cap cover
3
to establish a closed state, the mouth cap
19
is fitted with the output mouth
15
to provide a strong engagement therebetween, whereby an enhanced water shutoff effect can be obtained.
It goes without saying that the opening/closing hinge
4
pivotably connects the cap main body
2
and the cap cover
3
. In a state that the cap cover
3
is closed, centers of the cap cover
3
and the cap main body
2
coincide with each other and, naturally, the output mouth
15
is fitted in the mouth cap
19
.
In the first embodiment, the opening/closing hinge
4
, which has a spring band
24
and auxiliary connecting portions
25
provided on both sides of the spring band
24
, allows the cap cover
3
to be reversed in a state that the cap cover
3
is opened (completely) to such an extent (180° in the illustrated example) that the cap cover
3
does not become an obstacle when the contents flow through the output mouth
15
of the cap main body
2
, as well as to maintain such a state.
The spring band
24
is formed to assume a hook (inverted-L) sectional shape by means of a cut
28
extending between the outer circumferential wall
11
of the cap main body
2
and the top surface of the cap cover
3
with its lower and upper ends connected to the cap main body
2
and the cap cover
3
, respectively.
Therefore, if the spring band
24
is pushed from inside to outside in the radial direction (left to right in
FIG. 1
) at a position close to its lower end in a state that the cap cover
3
is closed (see FIG.
1
), resilient force in the spring band
24
against the pushing force builds up as the pushed portion warps inward (see FIGS.
2
and
3
). This resilient force urges the cap cover
3
in the closing direction until the angle of the cap cover
3
reaches a prescribed value. However, when the angle of the cap cover
3
has exceeded the prescribed value, the urging direction is reversed and the resilient force rotates the cap cover
3
in the opening direction. Finally, the resilient force almost disappears when the cap cover
3
is opened to a prescribed opening angle (see FIG.
4
). As a result, the opening state of the cap cover
3
at this time is maintained.
The manipulation body
5
is incorporated in such a manner that most of the main part thereof is accommodated under the top plate
10
of the cap main body
2
to be used to perform a manipulation of opening the cap cover
3
.
The manipulation body
5
has a push button portion
32
, a transmission rod
33
, a pushing end
34
, and an acting portion
35
.
The push button portion
32
penetrates through the outer circumferential wall
11
of the cap main body
2
and is exposed to outside. In terms of operationality and force transmission, it is preferable that the push button portion
32
be located as distant from the opening/closing hinge
4
as possible.
In the first embodiment, only one push button portion
32
is provided at such a position (front side of the container
7
) that the push button portion
32
and the opening/closing hinge
4
are symmetrical. Therefore, the outer circumferential wall
11
of the cap main body
2
is formed with a button through-hole
36
at a position (front side) corresponding to the push button portion
32
.
Although not shown in drawings, two push button portions
32
may be provided, for example, at right and left side positions of the cap main body
2
.
The pushing end
34
is located in such a manner as to squarely face the spring band
24
of the opening/closing hinge
4
from inside. Therefore, the outer circumferential wall
11
of the cap main body
2
is formed with, at a corresponding position (right behind the pushing end
34
), an acting end through-hole
37
for allowing the pushing end
34
to pass through it toward the inside surface of the opening/closing hinge
4
.
In the first embodiment, the pushing end
34
has a chip-like projection
38
. However, the invention is not limited to such a case including the projection
38
; for example, the pushing end
34
may be unified with the transmission rod
33
as described later (without providing any definite shape as the pushing end
34
).
In other wards, the pushing end
34
is provided for transmitting pushing force of the push button portion
32
to the opening/closing hinge
4
and thereby causing the cap cover
3
to open.
The transmission rod
33
connects the push button portion
32
and the pushing end
34
.
In the first embodiment, the transmission rod
33
having a ring shape connects the push button portion
32
and the pushing end
34
in two ways.
That is, the transmission rod
33
which is completely accommodated in the circumferential space (between the outer circumferential wall
11
and the inner circumferential wall
12
) of the cap main body
2
has a shape which surrounds the contents flow path provided in the cap main body
2
(inside the inner circumferential wall
12
) so as not to contact and interfere with the flow path in the cap main body
2
.
The transmission rod
33
having such a configuration is made of a resilient material (e.g., a resin or a metal) so as to cause a prescribed resilient force when an external force is applied to bend the transmission rod
33
in the longitudinal direction thereof.
The resilient material is required to have resilience to an extent that a force for pushing the opening/closing hinge
4
can be stored therein when the transmission rod
33
is bent during a manipulation stroke from a position where the pushing end
34
contacts the opening/closing hinge
4
to a position where the push button portion
32
is pushed thereafter by a prescribed length.
The transmission rod
33
having such resilience is capable of pushing the opening/closing hinge
4
all at once when a force for opening has increased to a certain level, whereby the cap cover
3
can be opened reliably.
The fact that the transmission rod
33
has a ring shape as described above is advantageous in that bend deformation of the transmission rod
33
is distributed to its right and left portions in a well-balanced manner (i.e., the ring shape of the transmission rod
33
is compressed in the longitudinal direction and expanded in the lateral direction while being kept symmetrical with respect to its center line) and hence the pushing end
34
is moved straightly.
With the above advantages, an attempt to open the cap cover
3
never fails and the manipulation of the cap is facilitated.
When the push button portion
32
is pushed to press the pushing end
34
against the opening/closing hinge
4
, (before, at the same time as, or after the pushing) the acting portion
35
contacts a proper portion of the cap cover
3
and transmits upward opening force to the cap cover
3
in accordance with the increase in the amount of pushing manipulation on the push button portion
32
.
Although the position of the acting portion
35
is not limited, the acting portion
35
in the first embodiment is provided on the top surface of the push button portion
32
.
Specifically, the acting portion
35
is formed in such a manner that the top surface of the push button portion
32
is inclined so as to descend toward the pushing end
34
side.
Corresponding to the acting portion
35
, a slide
40
projects downward from the cap cover
3
so as to be placed on the top portion of the acting portion
35
in a state that the cap cover
3
is closed. The bottom surface of the slide
40
is inclined in the same direction as the acting portion
35
is.
Therefore, a backward movement of the acting portion
35
causes cam action between the acting portion and the slide
40
, which in turn causes wedge action for pushing up the cap cover
3
.
With the above configuration, an attempt to open the cap cover
3
never fails and the manipulation of the cap is facilitated even when the water shutoff effect in a state that the cap cover
3
is closed is enhanced as described above.
In the hinge cap
1
having the above configuration, in a state that the cap cover
3
is closed (see FIG.
1
), the mouth cap
19
is fitted with the output mouth
15
and strong engagement is caused therebetween to provide an enhanced water shutoff effect.
When the push button portion
32
is pushed in this state (see FIGS.
2
and
3
), in the first stage, the pushing end
34
of the manipulation body
5
contacts the spring band
24
of the opening/closing hinge
4
from inside and the acting portion
35
contacts the slide
40
.
As the push button portion
32
is pushed further, the pushing end
34
starts to push the spring band
24
, the transmission rod
33
starts to store resilient force, and cam action between the acting portion
35
and the slide
40
transforms into wedge action.
As a result, the mouth cap
19
is lifted up and disengaged from the output mouth
15
and then the cap cover
3
is opened.
The cap cover
3
thus opened (see FIG.
4
), enables the contents be taken out through the output mouth
15
.
Of courase, such a manipulation of pushing the push button portion
32
can be performed by one hand.
In a state that the cap cover
3
is opened, since the main parts (excluding the push button portion
32
) of the manipulation body
5
is covered almost completely with the top plate
10
of the cap main body
2
, the manipulation body
5
cannot be seen and the appearance is made better as much.
Further, the contents hardly leak into the movable portion (the transmission rod
33
and its vicinity) between the manipulation body
5
and the cap main body
2
, which prevents the movement of the manipulation body
5
from being deteriorated.
FIG. 8
shows a hinge cap
1
according to a second embodiment of the invention.
The hinge cap
1
according to the second embodiment is different from that according to the first embodiment in that the push button portion
32
of the manipulation body
5
has an increased thickness so that the acting portion
35
provided on the top surface thereof is located at an upper position, whereby necessary and sufficient cam action and wedge action on the cap cover
3
can be provided even if the cap cover
3
is not formed with the slide
40
expressly.
This provides an advantage that the structure of the cap cover
3
is simplified, which leads to cost reduction.
The other part of the configuration, the other detailed structures, the method of use, the various functions and effects, etc. are almost the same as in the first embodiment, and hence are not described here in detail.
FIG. 9
shows a hinge cap
1
according to a third embodiment of the invention.
The hinge cap
1
according to the third embodiment is different from that according to the first embodiment in that the tip portion, exposed to the outside from the cap main body
2
, of the push button portion
32
of the manipulation body
5
is formed with a stopper projection
45
that contacts the opening periphery of the button through-hole
36
when the push button portion
32
is pushed by a prescribed length.
Therefore, the pushing length of the push button portion
32
can be restricted by the stopper projection
45
. This arrangement provides an advantage that damage to the manipulation body
5
and a phenomenon that the push button portion
32
goes out of place (i.e., the push button portion
32
is left in the cap main body
2
and does not return) due to excessive pushing can be prevented.
The other part of the configuration, the other detailed structures, the method of use, the various functions and effects, etc. are almost the same as in the first embodiment, and hence are not described here in detail.
FIG. 10
shows a hinge cap
1
according to a fourth embodiment of the invention.
The hinge cap
1
according to the fourth embodiment is based on almost the same object as that according to the third embodiment, that is, it is intended to restrict the pushing length of the push button portion
32
and thereby prevent damage to the manipulation body
5
and a phenomenon that the push button portion
32
goes out of place (i.e., the push button portion
32
is left in the cap main body
2
and does not return) due to excessive pushing.
The fourth embodiment is different from the third embodiment in that the push button portion
32
of the manipulation body
5
is provided with a stopper projection
45
at a position close to the root thereof and inside the cap main body
2
, and a stop nail
46
to engage the stopper projection
45
at a prescribed position is provided inside the cap main body
2
.
FIG. 11
shows a hinge cap
1
according to a fifth embodiment of the invention.
The hinge cap
1
according to the fifth embodiment is different from that according to the first embodiment in that the pushing end
34
of the manipulation body
5
is integrally formed with the transmission rod
33
(i.e., the pushing end
34
does not have an independently shaped portion as the chip-like projection
38
in the first embodiment).
However, since it is difficult to cause the pushing end
34
to contact the spring band
24
of the opening/closing hinge
4
unless some other structure is provided, in the fifth embodiment the cap cover
3
is provided with a pressure receiving portion
50
that projects toward the pushing end
34
.
The other part of the configuration, the other detailed structures, the method of use, the various functions and effects, etc. are almost the same as in the first embodiment, and hence are not described here in detail.
FIG. 12
shows a hinge cap
1
according to a sixth embodiment of the invention.
The hinge cap
1
according to the sixth embodiment is different from that according to the first embodiment in that the manipulation body
5
has only one transmission rod
33
and the push button portion
32
is connected to the pushing end
34
in one way.
This provides an advantage that the structure of the manipulation body
5
is simplified, which leads to cost reduction.
The other part of the configuration, the other detailed structures, the method of use, the various functions and effects, etc. are almost the same as in the first embodiment, and hence are not described here in detail.
FIG. 13
shows a hinge cap
1
according to a seventh embodiment of the invention.
Also in the hinge cap
1
according to the seventh embodiment, the manipulation body
5
has only one transmission rod
33
.
Further, measures for restricting the pushing length of the push button portion
32
and thereby preventing damage to the manipulation body
5
and a phenomenon that the push button portion
32
goes out of place (i.e., the push button portion
32
is left in the cap main body
2
and does not return) due to excessive pushing are taken.
Specifically, the push button portion
32
is provided with a stopper projection
45
at a position close to the root thereof and inside the cap main body
2
, and a stop nail
46
to engage the stopper projection
45
at a prescribed position is provided inside the cap main body
2
.
Although not shown in drawings, the push button portion
32
of the manipulation body
5
may be provided on the tip portion thereof exposed to outside of the cap main body
2
with a stopper projection
45
so as to be abutted against the opening periphery of the button through-hole
36
when the push button portion
32
is pushed by a prescribed length (as seen in FIG.
9
).
Incidentally, the invention is not limited to any of the above-described embodiments.
For example, the transmission rod
33
of the manipulation body
5
may be made of an unresilient material (e.g., rigid plastics or a hard metal).
In this case, when the push button portion
32
is pushed further from a state that the mouth cap
19
has been lifted up and disengaged from the output mouth
15
as a result of pushing on the push button portion
32
, the pushing end
34
abuts the spring band
24
of the opening/closing hinge
4
from inside. That is, this action does not store pushing force (resilient force) in the transmission rod
33
.
The materials of the cap main body
2
etc. are not limited to synthetic resins. Part or all of them may be made of a metal such as aluminum or stainless steel, glass, or the like.
The plan-view external shapes of the cap main body
2
etc. and container
7
are not limited to an ellipse, a circle, and the like, and may be modified so as to assume a rectangular shape, for example.
Other modifications to the embodiments can be made as appropriate.
As is apparent from the above description, in the hinge cap according to the invention, the cap main body has the deck portion and most of the manipulation body for transmitting pushing opening force to the inside surface of the opening/closing hinge is covered even in a state that the cap cover is opened. Therefore, the appearance is improved and the movement of the manipulation body does not deteriorate because the contents hardly leak into the movable portion of the manipulation body.
Further, since the transmission rod of the manipulation body is made of a resilient material, the opening/closing hinge can be pushed by strong force all at once, which provides an advantage that the cap cover can be opened easily and reliably.
Industrial Applicability
The present invention is useful as a cap that is used in a container such as a bottle for cosmetics.
