Japanese Patent Application Laid-Open No. 2004-292008

However, when using the conventional spout cap, it is necessary to open the spout by opening the upper lid around the outer hinge and then opening the small lid around the inner hinge. Therefore, it is necessary to perform the opening operation of the upper lid and the opening operation of the small lid separately, and there is room for improvement in opening operability.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a pouring cap which is excellent in opening operability.

(1) The pouring cap according to the present invention includes a cap body that covers the mouth of a container body in which contents are stored, and is connected to the cap body so as to be rotatable around a hinge so that the cap body can be opened and closed. and a lid covering the cap body, the cap body having a pouring nozzle for pouring out the contents, and a closing part for closing the mouth of the container body, and the closing part includes the cap body and a plug member formed of a softer material than the lid body and closing the pouring port of the pouring nozzle so as to be openable is provided, the plug member having a closed position for blocking the pouring port and a closing position for closing the pouring port. The lid body is elastically deformable between the closed position and the open position, and is restored and displaced from the closed position toward the open position. is elastically deformed from the open position toward the closed position, and when the cover moves to the closed position, the plug member is pressed against the open end of the pouring nozzle and positioned at the closed position. A pressing portion is formed.

According to the pouring cap according to the present invention, when the lid body is closed with respect to the cap body (positioned at the closed position), the plug member is pushed using the pressing portion formed on the lid body. It can be pressed against the open end of the dispensing nozzle to hold the plug member positioned in the closed position. As a result, the spout can be closed with high sealing performance, and leakage of the contents can be prevented. Therefore, the contents can be appropriately protected during product distribution and storage.

In use, when the lid is opened from the closed position toward the open position around the hinge, the pressing of the plug member by the pressing portion is released. is restored from the closed position toward the open position by elastic restoration deformation. As a result, the spout can be opened at the same time as the lid body is opened with respect to the cap body (positioned at the open position). Therefore, the pouring port can be opened at the same time by a single operation of opening the lid. Therefore, the contents can be poured out quickly, and it is easy to use. Therefore, it is possible to obtain a pouring cap with excellent opening operability.
In particular, when the plug member is released from being pressed by the pressing portion, the plug member begins to be restored and displaced from the closed position toward the open position by its own elastic restoring force. Therefore, using the restoration displacement of the plug member, it is possible to apply stress to the lid so as to push the lid toward the open position. As a result, the opening operation of the lid body can be performed smoothly, for example, even with a weak force, and the opening operability can be further improved.

In addition, in the process of closing the lid from the open position to the closed position after use, the lid can be used to elastically deform the plug member from the open position to the closed position, and also to move to the closed position. Sometimes a pusher can be used to push the plug member against the open end of the dispensing nozzle. Therefore, one operation of closing the lid can simultaneously perform the operation of closing the spout, which is also easy to use.

(2) The cap main body is formed with a fitting portion into which the lid is fitted when the lid moves to the closed position, and the plug member is attached to the fitting portion. When the fitting is released, the lid may be pushed up toward the open position by a restoring displacement from the closed position toward the open position.

In this case, the fitting portion can be used to undercut fit the lid body to the cap body, so that the lid body can be appropriately maintained in a closed state, and the lid can be unintentionally closed. It can prevent the body from opening. When used, the lid is opened only to the extent that the fitting of the lid to the fitting portion is released, and thereafter, the lid is moved toward the open position by utilizing the restoring displacement of the plug member. can be pushed up. Therefore, the lid can be opened smoothly.
In this manner, the closed state of the lid can be properly maintained, and the lid can be smoothly opened by utilizing the restoring displacement of the plug member when the lid is opened.

(3) The plug member has a slit valve that closes the spout, is formed integrally with the valve member attached to the spout nozzle, and is formed integrally with the valve member so as to switch between the closed position and the open position. an elastic piece that can be elastically deformed therebetween, wherein the slit valve is formed on an elastic film that closes the spout, and is formed on the elastic film and can be opened and closed by elastic deformation of the elastic film; a slit portion for pouring out a substance, wherein the elastic piece is elastically deformed from the open position toward the closed position as the lid moves from the open position to the closed position; When the lid moves to the closed position, it may be positioned in a state of being pressed against the elastic membrane to block the spout through the slit.

In this case, since the plug member is provided with a slit valve, after the lid is opened and the elastic piece is displaced to the open position, the internal pressure of the container body or the flow pressure of the contents can be used. By elastically deforming the elastic membrane, the slit portion can be widened. Thereby, the content can be poured out through the slit portion. In particular, by using the slit part, it is possible to pour out the contents in a pouring mode such as pouring out a certain amount of pouring while improving the cutting of the contents. By providing the slit valve in this way, it is possible to handle various contents, and convenience can be improved.

ADVANTAGE OF THE INVENTION According to this invention, it can be set as the pouring cap excellent in unsealing operability.

(First embodiment)
A first embodiment of a pouring cap according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the pouring cap 1 of the present embodiment is a cap that is used while being attached to the mouth portion 3 of a bottomed cylindrical container body 2 in which contents are contained.
The container body 2 is not particularly limited, but examples thereof include a glass bottle and a synthetic resin bottle. Although the contents contained in the container body 2 are not particularly limited, for example, contents having fluidity such as liquid foods and liquid seasonings can be suitably used.

The pouring cap 1 includes a cylindrical cap body 10 that covers the mouth portion 3 of the container body 2, and a capped tube that is rotatably connected to the cap body 10 around a hinge portion 11 and covers the cap body 10 so that it can be opened and closed. and a lid body 12 having a shape. The spout cap 1 is a molded component in which a cap main body 10 and a lid body 12 are integrally formed by molding a synthetic resin material such as PE (polyethylene) or PP (polypropylene).

In FIG. 1, the mouth portion 3 of the container body 2, the cap body 10 and the lid body 12 are arranged such that their central axes are on a common axis. Hereinafter, this common axis will be referred to as a cap axis O, the lid body 12 side along the cap axis O will be referred to as an upper side, and the container body 2 side that is the opposite side will be referred to as a lower side. Further, in a plan view seen from the direction of the cap axis O, a direction intersecting the cap axis O is called a radial direction, and a direction rotating around the cap axis O is called a circumferential direction.
Further, of the radial directions, two directions that are orthogonal to each other are referred to as a front-rear direction L1 and a left-right direction L2. One direction along the front-rear direction L1 is referred to as the front, and the opposite direction is referred to as the rear.

A first engagement projection 4 projecting radially outward is formed on the outer peripheral surface of the upper end portion of the mouth portion 3 of the container body 2 . In addition, the first engagement protrusion 4 may be formed in a ring shape, or may be formed in plural at intervals in the circumferential direction.
It should be noted that the present invention is not limited to the case where the first engaging projections 4 are formed. For example, a male threaded portion may be formed on the outer peripheral surface of the mouth portion 3 of the container body 2 instead of the first engaging projections 4 . .

The cap body 10 includes a seal cylinder 20 fitted inside the mouth portion 3 of the container body 2, a mounting cylinder 21 surrounding the mouth portion 3 from the outside in the radial direction, and a surrounding cylinder further surrounding the mounting cylinder 21 from the outside in the radial direction. 22 , and a closing portion 23 that is connected to the upper end portion of the seal tube 20 and covers and closes the mouth portion 3 of the container body 2 .

The seal tube 20 and the mounting tube 21 are each formed to protrude upward from the upper open end of the mouth portion 3 of the container body 2 . The upper end portion of the sealing cylinder 20 and the upper end portion of the mounting cylinder 21 are connected via an annular flange portion 25 arranged above the upper open end of the mouth portion 3 of the container body 2 .
Therefore, an annular space is formed between the upper open end of the mouth portion 3 of the container body 2 and the flange portion 25 . However, the present invention is not limited to this case, and for example, the flange portion 25 may be formed so as to contact the top open end of the mouth portion 3 of the container body 2 .

A second engagement projection (fitting portion) 26 is formed on the outer peripheral edge portion of the flange portion 25 so as to protrude outward in the radial direction. The second engagement projection 26 plays a role of fitting the lid 12 when the lid 12 moves to the closed position P3.
In addition, the second engaging projection 26 may be formed in an annular shape, or may be formed in plurality at intervals in the circumferential direction. Further, the second engaging projection (fitting portion) 26 is not limited to being formed on the outer peripheral edge of the flange 25, and may be formed on the outer surface (upper surface) of the flange 25 or the outer peripheral surface of the mounting cylinder 21, for example. It does not matter if they are formed. In any case, the second engaging projection 26 may be formed at any position on the cap body 10 as long as it is in a position where it can be fitted with the lid body 12 .

The cap body 10 is fitted and fixed to the mouth portion 3 by inserting the mouth portion 3 into an annular groove formed between the seal cylinder 20 and the mounting cylinder 21 by, for example, plugging. At this time, since the sealing cylinder 20 and the mounting cylinder 21 sandwich the opening 3 from inside and outside, they are mounted on the opening 3 with a strong fitting force. The seal cylinder 20 is fitted, for example, airtightly inside the mouth portion 3 of the container body 2 to properly seal the inside of the container body 2 .

The mounting cylinder 21 is undercut-fitted to the mouth portion 3 of the container body 2 . Specifically, on the inner peripheral surface of the lower end of the mounting cylinder 21, third engaging projections 27 that engage with the first engaging projections 4 formed on the outer peripheral surface of the mouth portion 3 are directed radially inward. The third engaging projection 27 is undercut-fitted to the first engaging projection 4 .
The third engaging projection 27 may be formed in an annular shape as long as it can be fitted under the first engaging projection 4, and a plurality of the third engaging projections 27 are formed at intervals in the circumferential direction. It doesn't matter if

However, the method of attaching the attachment tube 21 to the mouth portion 3 of the container body 2 is not limited to undercut fitting by capping or the like. For example, as described above, when a male threaded portion is formed on the outer peripheral surface of the mouth portion 3 of the container body 2, a female threaded portion screwed to the male threaded portion may be formed on the inner peripheral surface of the mounting cylinder 21. Alternatively, the mounting cylinder 21 may be mounted to the mouth portion 3 of the container body 2 by screwing.

The surrounding tube 22 is formed in a tubular shape that surrounds the mounting tube 21 from the outside in the radial direction and secures an annular gap with the mounting tube 21 . In the illustrated example, the surrounding tube 22 is formed such that the upper end is located below the upper end of the mounting tube 21 and the lower end is located below the lower end of the mounting tube 21 . . However, the positional relationship between the surrounding tube 22 and the mounting tube 21 is not limited to this case.

The inner peripheral surface of the surrounding cylinder 22 and the outer peripheral surface of the mounting cylinder 21 are connected to each other via, for example, a connecting piece 28 that is easily broken. In the illustrated example, a plurality of connecting pieces 28 are formed at intervals in the circumferential direction. However, it is not limited to this case, and the connecting piece 28 may be formed in an annular shape to connect the inner peripheral surface of the surrounding cylinder 22 and the outer peripheral surface of the mounting cylinder 21 over the entire circumference.

Note that the surrounding cylinder 22 is not an essential component of the cap main body 10 and may be omitted. In this case, for example, the mounting cylinder 21 and the lid body 12 may be connected via the hinge portion 11 .

As shown in FIGS. 1 and 2, the closing portion 23 is formed by a closing wall 30 that closes the upper end of the seal cylinder 20, and a central portion of the closing wall 30 that protrudes upward. and a head portion 31 having a truncated tubular shape. 2, illustration of the lid 12 and a plug member 40, which will be described later, is omitted.

The head portion 31 includes a front wall 32 and a rear wall 33 arranged to face each other with a gap in the front-rear direction L1, a pair of side walls 34 arranged to face each other with a gap in the left-right direction L2, and a front wall. 32 , a rear wall 33 , and a top wall 35 connected to the upper ends of a pair of side walls 34 .

The front wall 32 is arranged to face forward and has a flat inclined wall surface formed to extend rearward as it goes upward. The rear wall 33 is arranged to face rearward and has a flat inclined wall surface formed to extend forward as it goes upward. The upper end of the rear wall 33 is positioned rearward of the upper end of the front wall 32 and lower than the upper end of the front wall 32 .
Thus, the top wall 35 is formed to be slightly inclined rearward with respect to the cap axis O in accordance with the height relationship between the upper end of the front wall 32 and the upper end of the rear wall 33 . .
The pair of side walls 34 are formed in a flat shape extending substantially vertically upward from the closing wall 30 .

The head portion 31 formed as described above is formed in a rectangular shape in plan view in which the length along the front-rear direction L1 is longer than the width along the left-right direction L2. However, the shape of the head portion 31 is not limited to this case, and may be formed, for example, so as to bulge upward in a hemispherical shape.

The front wall 32 of the head portion 31 is formed with a pouring nozzle 36 for pouring out the contents.
The pouring nozzle 36 is formed integrally with the front wall 32 so as to surround a through-hole 32a formed to penetrate the front wall 32 in the front-rear direction L1. The pouring nozzle 36 is formed in a straight shape extending forward and obliquely upward from the front wall 32 . The inside of the pouring nozzle 36 communicates with the interior of the container body 2 through the through hole 32a and opens forward through the pouring port 36a. As a result, it becomes possible to pour out the contents inside the container body 2 to the outside through the pouring nozzle 36 .
Note that the pouring nozzle 36 has a length that does not protrude radially outward from the mounting cylinder 21 .

The top wall 35 of the head portion 31 is integrally formed with a projection portion 37 projecting upward. The projecting portion 37 includes a shaft portion 37a formed in a circular cross-sectional view, and a head portion 37b formed at the upper end portion of the shaft portion 37a and having a larger diameter than the shaft portion 37a.

As shown in FIGS. 1 and 3, the closing portion 23 configured as described above is made of a softer material than the cap main body 10 and the lid body 12 so that the spout 36a of the spout nozzle 36 can be opened. A closing plug member 40 is provided.
The plug member 40 is made of an elastic material such as silicone rubber, and is formed separately from the cap main body 10 and the lid body 12 . In the illustrated example, the plug member 40 is formed in a plate (L-shaped) shape longer in the front-rear direction L1 than its lateral width along the left-right direction L2. The lateral width of the plug member 40 along the left-right direction L<b>2 is the same as the lateral width of the head portion 31 .

The plug member 40 is arranged so as to overlap the top wall 35 of the head portion 31 and is integrally connected to a base portion 41 covering the top wall 35 and the pouring nozzle 36 from above, and a front end portion of the base portion 41 . An elastic piece 42 that can be elastically deformed in an angle range of approximately 180 in the vertical direction with the connecting portion as a base point.
Specifically, the elastic piece 42 is elastically deformed between a closed position P1 (see FIG. 1) that closes the spout 36a of the spout nozzle 36 and an open position P2 (see FIG. 3) that opens the spout 36a. It is possible. In particular, the elastic piece 42 is formed so as to always be restored and displaced upward, that is, always restored and displaced from the closed position P1 toward the open position P2.
The elastic piece 42 is formed with a bulging portion 43 that enters the inside of the spout 36a to block the spout 36a when positioned at the closed position P1.

A fitting hole 41a is formed in the base portion 41 of the plug member 40 so as to penetrate the base portion 41 in the vertical direction. As a result, the plug member 40 overlaps the top wall 35 with the shaft portion 37a of the protrusion 37 fitted in the fitting hole 41a. At this time, the plug member 40 is pressed between the top wall 35 and the head portion 37 b of the protrusion 37 .
As a result, the plug member 40 is integrally combined with the head portion 31 using the protrusion 37 formed on the top wall 35 .

As shown in FIGS. 1 and 3, the lid 12 is formed in a truncated tubular shape having a peripheral wall 50 and a ceiling wall 51, covers the entire closing portion 23 of the cap body 10 from above, and has a hinge. It can be opened and closed by rotating around the portion 11 . Therefore, the lid body 12 rotates around the hinge portion 11 to move between a closed position P3 (see FIG. 1) attached to the cap body 10 and an open position P4 (see FIG. 3) separated from the cap body 10. and .

The peripheral wall 50 is placed on the upper open end of the surrounding tube 22 of the cap body 10 when the lid 12 is positioned at the closed position P3 as shown in FIG. It is undercut fitted to the projection 26 . As a result, the lid body 12 is positioned at the closed position P3, and is suppressed from being opened at an unintended timing.

However, it is not limited to the case where the lower end portion of the peripheral wall 50 is undercut-fitted to the second engaging projection 26 . As described above, the lid body 12 is fitted (including undercut fitting) to the second engaging projection (engaging portion) 26 provided at an arbitrary location of the cap body 10. It should be configured. For example, a second engaging protrusion (fitting portion) 26 is formed on the upper surface of the flange portion 25 of the cap body 10 . In addition, a wall portion may be formed so as to hang down from the ceiling wall 51 of the lid body 12, and the wall portion and the second engaging projection 26 may be fitted.

The hinge portion 11 integrally connects the lower end portion of the peripheral wall 50 of the lid body 12 and the upper end portion of the surrounding tube 22 of the cap body 10 . At this time, the hinge portion 11 is formed so that the circumferential position thereof is the same as that of the rear wall 33 of the head portion 31 . This makes it possible to open and close the lid body 12 toward the opposite side in the radial direction (toward the rear) with respect to the cap axis O from the pouring nozzle 36 .

A knob 52 protruding radially outward is formed in a portion (front portion) of the peripheral wall 50 of the lid body 12 located on the opposite side of the hinge portion 11 across the cap axis O. . Therefore, by using the tab 52, the lid 12 can be easily opened and closed around the hinge portion 11. As shown in FIG.

As shown in FIG. 3, the plug member 40 described above is positioned on the rotational locus M of the peripheral wall 50 of the lid body 12 that rotates around the hinge portion 11 when the elastic piece 42 is positioned at the open position P2. is designed to As a result, the lid body 12 moves from the open position P4 toward the closed position P3 while rotating about the hinge portion 11, and presses the elastic piece 42 of the plug member 40 from above. 42 can be elastically deformed from the open position P2 toward the closed position P1.

Further, the cover 12 has a pressing portion 55 which presses the elastic piece 42 of the plug member 40 against the open end of the pouring nozzle 36 to position it at the closed position P1 when it is positioned at the closed position P3 as shown in FIG. is formed.
The pressing portion 55 is arranged at the corner between the front portion of the peripheral wall 50 and the ceiling wall 51, and is a pressing surface perpendicular to the center line C of the pouring nozzle 36 when the lid body 12 is positioned at the closed position P3. It is formed in a block shape with 55a. As a result, the pressing portion 55 can press the entire elastic piece 42 against the pouring nozzle 36 using the pressing surface 55a, thereby positioning the elastic piece 42 at the closed position P1. It is possible to block the spout 36a.

1 to 3, the top wall 51 of the lid 12 is formed with a pair of guide plates 56 extending downward and facing each other with a gap in the left-right direction L2. It is The pair of guide plates 56 are formed in a rectangular shape that is longer in the front-rear direction L1 than in the up-down direction in a side view when the lid body 12 is positioned at the closed position P3, and sandwiches the head portion 31 in the left-right direction. It is arranged so as to face L2. A pair of guide plates 56 cover a portion of the top wall 35 and a portion of the front wall 32 of the head portion 31 from the outside in the left-right direction L2. In the illustrated example, the pair of guide plates 56 are formed so as to be integrally connected to the front portion of the peripheral wall 50 .
As a result, the pair of guide plates 56 can be used to press the elastic piece 42 against the pouring nozzle 36 while suppressing twisting of the elastic piece 42 in the left-right direction L2.

(Action of pouring cap)
Next, the case of pouring out the contents using the pouring cap 1 configured as described above will be described.

First, as shown in FIG. 1, when the lid 12 is closed with respect to the cap body 10 (positioned at the closed position P3), the pressing portion 55 formed on the lid 12 is used to The elastic piece 42 of the plug member 40 can be pressed against the open end of the pouring nozzle 36, and the elastic piece 42 of the plug member 40 can be held in the closed position P1. As a result, the spout 36a can be closed with high sealing performance, and leakage of the contents can be prevented. Therefore, the contents can be appropriately protected during product distribution and storage.

In particular, since the lid body 12 is undercut-fitted to the cap body 10 by using the second engaging projections 26, the closed state of the lid body 12 can be appropriately maintained, and the unintentional It is possible to suppress the lid body 12 from opening unnecessarily.

Next, when pouring out the contents, the lid 12 is rotated from the closed position P3 shown in FIG. 1 toward the open position P4 shown in FIG. perform the opening operation. Then, the elastic piece 42 is released from the pressing portion 55, so that the elastic restoring force of the elastic piece 42 is restored from the closed position P1 toward the open position P2 as the cover 12 is opened. be able to. As a result, the spout 36a can be opened at the same time that the lid 12 is opened with respect to the cap main body 10 (positioned at the open position P4).

Therefore, the operation of opening the spout 36a can be simultaneously performed by a single operation of opening the lid 12. FIG. Therefore, the contents can be poured out quickly, and it is easy to use. Therefore, the pouring cap 1 having excellent opening operability can be obtained.

In particular, when the lid 12 is opened, if the gripping piece 52 is used to lift the lid 12 to the extent that the fitting of the lid 12 to the second engaging projection 26 is released, the elastic force of the pressing portion 55 is increased. Combined with the fact that the pressing of the piece 42 is released, the elastic piece 42 begins to be restored and displaced from the closed position P1 toward the open position P2 by its own elastic restoring force. Therefore, using the restoring displacement of the elastic piece 42, stress can be applied to the lid 12 so as to push the lid 12 toward the open position P4 as indicated by the arrow F shown in FIG. . As a result, the opening operation of the lid body 12 can be performed smoothly, for example, even with a weak force, and the opening operability can be further improved.

As described above, according to the pouring cap 1 of the present embodiment, the pouring cap 1 can be easily opened and is easy to use.
When pouring out the content after opening the spout 36a of the spouting nozzle 36 by opening the lid 12, for example, the container body 2 is gripped, and the container body 2 is held as shown in FIG. While tilting the posture of , for example, the container body 2 is squeezed to increase the internal pressure. As a result, the contents in the container body 2 can be poured out through the pouring port 36 a of the pouring nozzle 36 . In addition, instead of squeezing the container body 2, tilting the container body 2 makes it possible to pour out the contents using its own weight. In this case, the container body 2 may be further squeezed while tilting the container body 2 .
Although FIG. 4 illustrates the case where the content is poured out in the form of droplets, the pouring mode is not limited to this case. For example, it is also possible to pour out the contents linearly.

Further, after pouring out the contents, when the lid 12 is rotated around the hinge portion 11 and closed from the open position P4 toward the closed position P3, it is positioned at the open position P2 as shown in FIG. Since the elastic pieces 42 are arranged on the rotational locus M of the lid 12, the elastic pieces 42 are directed from the open position P2 to the closed position P1 by using the lid 12 in the process of closing the lid 12. can be elastically deformed. Then, as shown in FIG. 1, when the lid body 12 is shifted to the closed position P3, the pressing portion 55 can be used to press the elastic piece 42 of the plug member 40 against the opening end of the pouring nozzle 36. can.
Therefore, one operation of closing the lid 12 can simultaneously perform the operation of closing the spout 36a, which is also easy to use.

(Second embodiment)
Next, a second embodiment of the pouring cap according to the present invention will be described with reference to the drawings. In addition, in the second embodiment, the same reference numerals are given to the same parts as the constituent elements in the first embodiment, and the description thereof will be omitted.

As shown in FIGS. 5 and 6, the pouring cap 60 of the present embodiment is integrally combined with the cap body 10 by attaching the plug member 61 to the pouring nozzle 36 .
The plug member 61 includes a valve member 62 attached to the pouring nozzle 36, and an elastic piece 42 formed integrally with the valve member 62 and elastically deformable between a closed position P1 and an open position P2. there is

The valve member 62 has a mounting cylinder 63 attached to the pouring nozzle 36, and a slit valve 64 formed integrally with the mounting cylinder 63 and closing the pouring port 36a.
As shown in FIGS. 5 to 7, the slit valve 64 closes the spout 36a, and is formed on a thin elastic membrane 65 that can be elastically deformed. It has a slit part 66 which can be opened and closed and which pours out the contents. 7, illustration of the elastic piece 42 is omitted.

As shown in FIG. 7, the slit portion 66 is formed radially around the center line C, for example, in a cross shape when viewed from above in the direction of the center line C of the pouring nozzle 36 . However, the shape of the slit portion 66 is not limited to a cross shape in plan view, and may be changed to another shape such as a straight line shape in plan view according to, for example, the pouring mode and the properties of the contents. I do not care.

As shown in FIGS. 5 and 6, the elastic piece 42 is formed integrally with the upper portion of the mounting cylinder 63 and is elastically deformable in an angle range of approximately 180 in the vertical direction. As a result, the elastic piece 42 is elastically deformed from the open position P2 toward the closed position P1 as the lid body 12 moves from the open position P4 to the closed position P3, and the lid body 12 moves to the closed position P3. In some cases, it is positioned in a state of being pressed against the elastic membrane 65 so that the spout 36a can be closed via the slit portion 66 .

Even in the case of this embodiment, when the elastic piece 42 is positioned at the open position P2, it is designed to be positioned on the rotational locus M of the peripheral wall 50 of the lid body 12 that rotates around the hinge portion 11. It is Therefore, as the lid body 12 moves from the open position P4 toward the closed position P3, the elastic piece 42 can be pressed from above and elastically deformed from the open position P2 toward the closed position P1. It is

(Action of pouring cap)
Even with the pouring cap of this embodiment, it is possible to achieve the same effects as those of the first embodiment.
In addition, since the plug member 61 is provided with the slit valve 64, after the lid 12 is opened and the elastic piece 42 is displaced to the open position P2, for example, the internal pressure of the container body 2 or the flow pressure of the contents is reduced. By elastically deforming the elastic film 65 by using, for example, the slit portion 66 can be expanded. Thereby, the contents can be poured out through the slit portion 66 .
In particular, by using the slit portion 66, it is possible to pour out the contents in a pouring mode such as pouring out a certain amount of pouring while improving the cutability of the contents. Therefore, it is possible to handle various contents, and convenience can be improved.

Although the embodiment of the present invention has been described above, the present embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. Modifications may be combined as appropriate. Furthermore, the present embodiment and its modifications include, for example, those that can be easily assumed by those skilled in the art, those that are substantially the same, and those within an equivalent range.
