  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that in all the drawings, the same components are denoted by the same reference numerals, and redundant description will be omitted as appropriate.

As shown in FIG. 1 to FIG. 7, the liquid agent discharge container 100 according to this embodiment includes a container body 10 that stores the liquid agent 150 and the liquid agent 150 from the discharge port 41 by being pushed down relative to the container body 10. A head part 30 for discharging the liquid, a mounting part 52 attached to the container body 10 and holding the head part 30 so as to be movable up and down, and a shaft support part (for example, the shaft part 22) swingable with respect to the mounting part 52. And a cover portion 20 that is supported by the shaft support recess 54a and covers the head portion 30 from above.
Here, the front end side of the swinging portion of the cover 20 is defined as the front with respect to the shaft support in plan view. The head portion 30 includes a head main body portion 31 and a nozzle portion 40 that protrudes forward from the head main body portion 31 and has a discharge port 41 formed at a tip portion.
The liquid agent discharge container 100 is moved forward by moving the nozzle portion 40 relative to the head body portion 31 in conjunction with the swinging of the cover portion 20 with respect to the mounting portion 52 about the shaft support portion by a pressing operation. A mechanism (for example, a forward force applying surface constituted by a part of the guide groove 27b and a forward force receiving projection 46) is further provided.
Therefore, since the nozzle portion 40 moves forward by pressing the cover portion 20, even if the nozzle portion 40 is formed short so that dripping from the discharge port 41 at the tip portion of the nozzle portion 40 is suppressed, the cover portion 20 can prevent the discharge port 41 at the tip of the nozzle portion 40 from being covered.

The cover part 20 and the head part 30 are action parts (for example, constituted by the protrusion part 33 and the action surface 29a) that transmit a pressing force from the cover part 20 to the head part 30. They are connected to each other at the action portion located between the moving tip portion and the shaft support portion.
When the cover portion 20 is pressed, the pressing force is transmitted from the cover portion 20 to the head portion 30 at the operating portion while the cover portion 20 swings with respect to the mounting portion 52 with the shaft support portion serving as a fulcrum. The liquid agent discharge container 100 is configured such that the portion 30 is pushed down relative to the mounting portion 52 and the container body 10.

1, 2, 3 (a), 3 (b), 4 (a), 4 (b), 5 (a), and 5 (b), the states shown in FIG. This is a normal state (normal state) in which the part 20 and the head part 30 are not pressed down.
On the other hand, the state shown in FIGS. 7A and 7B is a state in which the cover unit 20 and the head unit 30 are pushed down to the lower limit position (hereinafter may be simply referred to as a pressed state).
Moreover, the states shown in FIGS. 6A and 6B are intermediate states between the normal state and the pressed state.

  The liquid agent discharge container stuffed product 200 according to the present embodiment includes the liquid agent discharge container 100 according to the present embodiment and the liquid agent 150 filled in the container body 10.

In the present embodiment, the liquid agent 150 is exemplified as one that is discharged in the form of foam. As such a liquid agent, hand soap can be mentioned as a representative example, but it is not limited thereto, facial cleansing agent, cleansing agent, dish detergent, hair conditioner, body soap, shaving cream, foundation, beauty liquid, etc. Examples of various skin cosmetics, hair dyes, disinfectants, and the like that are used in the form of foam can be given.
In addition, the liquid agent 150 in the present invention is not limited to those discharged in the form of foam, but also includes those discharged as fluid liquid agents. Such liquid agents 150 include hand soaps, face wash, Examples include cleansing agents, dishwashing detergents, hair conditioners, body soaps, shaving gels, skin cosmetics such as foundations and beauty liquids, hair dyes, disinfectants, and the like.

The liquid agent 150 is stored in the container body 10 at normal pressure or under pressure. The liquid agent discharge container 100 changes the liquid agent 150 into a foam by bringing the liquid agent 150 stored at normal pressure into contact with air or by releasing the liquid agent 150 stored under pressure to atmospheric pressure at the time of discharge. . In the present specification, the foam-like liquid 150 is referred to as a foam and is distinguished from the non-foam-like liquid 150 stored in the container body 10.
The liquid agent discharge container 100 is, for example, a mechanical pump container, and discharges the liquid agent 150 as a foam by indirectly pressing the head unit 30 via the cover unit 20.
However, unlike the present embodiment, the liquid agent discharge container may be configured to discharge the liquid agent 150 (foam) using a high-pressure gas stored in a cylinder or the like.

  Although the shape of the container body 10 is not particularly limited, for example, as shown in FIG. 1, the container body 10 is connected to the cylindrical body 11 and the upper side of the body 11, and has a lumen extending upward. It has a shape having a shoulder portion 12 whose plane cross-sectional area is reduced, a cylindrical mouth-neck portion 13 connected to the upper side of the shoulder portion 12, and a bottom portion 14 closing the lower end of the body portion 11. Yes. Although the material of the container main body 10 is not specifically limited, The container main body 10 is shape | molded, for example with the synthetic resin. An opening is formed at the upper end of the mouth-and-neck portion 13.

Moreover, the cap 50 with a liquid agent discharge device according to the present embodiment is configured by a portion excluding the container main body 10 in the structure of the liquid agent discharge container 100.
That is, the cap 50 with a liquid agent discharger is attached to the container body 10 and the head unit 30 that discharges the liquid agent 150 from the discharge port 41 by being pushed down relative to the container body 10 that stores the liquid agent 150. A mounting part 52 that holds the head part 30 so as to be movable up and down; a cover part 20 that is pivotally supported by the pivotal support part so as to be swingable with respect to the mounting part 52 and covers the head part 30 from above; And an advance mechanism.

  The mounting portion 52 is detachably mounted on the mouth and neck portion 13 by, for example, a fastening method such as screwing. As a result, the mounting portion 52, the head portion 30, and the cover portion 20 are attached to the mouth and neck portion 13. The entire cap 50 with a liquid agent discharger is attached. By mounting the cap 50 with a liquid agent dispenser on the mouth / neck portion 13, the opening of the mouth / neck portion 13 is closed by the cap 50 with a liquid agent dispenser.

The mounting portion 52 includes a cylindrical portion having a thread formed on the inner peripheral surface, and a top surface portion that closes the upper end of the cylindrical portion except for the central portion of the upper end.
The cap 50 with a liquid dispenser further includes a cylindrical intermediate cylinder 53 protruding upward from the top surface portion of the mounting portion 52.

  In this specification, the left direction in FIGS. 1 and 2 is referred to as the front, and the right direction is referred to as the rear. 1 and 2 is referred to as the left side, and the near side direction is referred to as the right side. Note that the axial direction of the shaft support portion is the left-right direction.

  The head main body 31 is held by the intermediate cylinder 53 so as to be movable relative to the intermediate cylinder 53 in the axial direction of the intermediate cylinder 53 (that is, in the vertical direction). The head main body 31 includes, for example, an outer cylinder part 32 disposed along the outer peripheral surface of the intermediate cylinder 53 and an inner cylinder part 34 disposed along the inner peripheral surface of the intermediate cylinder 53 (FIG. 4B). )). The axial directions of the intermediate cylinder 53, the outer cylinder portion 32, and the inner cylinder portion 34 are vertical directions, and the head main body portion 31 is guided in the vertical direction by the intermediate cylinder 53.

In a normal state (normal state) in which the head part 30 is not pushed down by the cover part 20, the vertical position of the head part 30 with respect to the intermediate cylinder 53 becomes the upper limit position by the action of the spring body 58 shown in FIG. 1, FIG. 2, FIG. 4 (a), (b) etc.).
On the other hand, when the user performs a pressing operation on the cover part 20, the head part 30 is pushed down against the urging force of the spring body 58 by being pushed downward by the cover part 20. As a result, as shown in FIGS. 7A and 7B, the outer cylinder portion 32 descends relative to the intermediate cylinder 53 and the outer cylinder portion 32 approaches the mounting portion 52. For example, the outer cylinder portion The intermediate cylinder 53 is covered by 32.
When the pressing operation on the cover unit 20 is released, the head unit 30 rises according to the bias of the spring body 58 and returns to the normal state.

As shown in FIG. 2, the cap 50 with a liquid agent discharger includes a piston 55, a housing 56, a suction pipe 57, and a foam generating unit 51 in addition to the head unit 30, the intermediate cylinder 53, the mounting unit 52, and the spring body 58. ing.
The housing 56 accommodates the piston 55 and the spring body 58 and communicates with the discharge port 41 via the intermediate cylinder 53, the inner cylinder part 34, and the nozzle part 40.
The suction pipe 57 is a pipe that sucks up the liquid agent 150 in the container main body 10, communicates with the inside of the housing 56, and hangs downward from the housing 56.
The housing 56 and the suction tube 57 are located inside the container body 10 in a state where the cap 50 with a liquid agent discharger is attached to the mouth and neck portion 13.
The piston 55 can reciprocate in the vertical direction within the housing 56. A spherical valve body 59 is formed at the lower end of the piston 55. The valve body 59 prevents the liquid agent 150 stored in the housing 56 and the suction pipe 57 from flowing down. When the head part 30 is pushed down by the user pushing down the cover part 20, the piston 55 raises the air pressure inside the housing 56 while the piston 55 restricts the rise (opening) of the valve body 59 at the lower end. . The piston 55 is provided with a small-sized liquid flow path (not shown) that allows the housing 56 and the head portion 30 to communicate with each other. Since the opening area of the liquid flow path is sufficiently small, the air pressure of the housing 56 is increased by pushing down the head part 30, and then the liquid agent 150 is pushed up from the housing 56 to the head part 30. The head portion 30 is provided with an air flow path (not shown) communicating with the outside.
Inside the cap 50 with a liquid agent discharger, a foam generation unit 51 is provided on the flow path of the liquid agent 150. In the foam production | generation part 51, when the air is sprayed with respect to the liquid agent 150, the liquid agent 150 turns into a rough bubble. By passing the coarse bubbles through the mesh arranged in the subsequent stage in the bubble generating unit 51, a fine and uniform foam is obtained. The foam is introduced from the inside of the inner cylinder portion 34 into the nozzle portion 40 through the liquid supply hole 36 and the introduction hole 42 in this order, and is discharged from the discharge port 41 via the nozzle portion 40.
When the pressing operation of the cover unit 20 is released, the spring body 58 is elastically restored, so that the piston 55 is restored to the upper position. As a result, the inside of the housing 56 has a low pressure, the valve body 59 is opened, and a new liquid 150 is sucked up into the housing 56 through the suction pipe 57. In addition, the inside of the cap 50 with a liquid agent discharger is maintained at atmospheric pressure by the outside air being taken into the inside of the cap 50 with a liquid agent discharger through the air flow path.
The structure and operation of the cap 50 with a liquid dispenser described here is merely an example, and other widely known structures can be applied to the present embodiment.

The cover portion 20 includes, for example, a top portion 21a located above the head portion 30, and a pair of side wall portions 21b and 21c that are located on the side of the head portion 30 and extend in the front-rear direction, respectively. It is convexly convex upward in a vertical cross section parallel to the axial direction of the support.
For this reason, the user can press down the cover part 20 so as to wrap the cover part 20 by hand. Therefore, it becomes easy to perform a pressing operation on the cover unit 20 stably while suppressing wobble.
That is, it is possible to more stably perform the operation of pushing down the head unit 30 using the lever principle.

Here, it is preferable that the lower ends of the pair of side wall portions 21b and 21c are located below the upper surface of the head main body portion 31, and in this way, when the cover portion 20 is pressed, It is suppressed that a finger is sandwiched between the portion 20 and the head main body portion 31.
However, the lower ends of the pair of side wall portions 21 b and 21 c may be positioned at the same height as the upper surface of the head main body portion 31, or may be positioned above the upper surface of the head main body portion 31.

  More preferably, as shown in FIGS. 4 (a), 6 (a), and 7 (a), in the side view of the cap 50 with a liquid agent dispenser as viewed in the axial direction of the shaft support portion, It covers the entire gap 61 between the head main body 31 and the cover part 20 (the gap between the mouth neck part 13 and the cover part 20 in the height direction). Thereby, when pressing down the cover part 20, it is suppressed more suitably that a finger is pinched between the cover part 20 and the head main body part 31.

  As shown in FIGS. 3A and 3B, each of the pair of side wall portions 21b and 21c includes a vertically upstanding portion. For this reason, compared with the case where the cover part is formed in, for example, an umbrella shape, a moment that promotes wobbling when the cover part 20 is pressed is less likely to act. Can be pressed down.

More specifically, the cover portion 20 (the cover main body 21) is formed in a convex dome shape. For this reason, it is possible to more easily perform the operation of depressing the cover part 20 so as to wrap the cover part 20 by hand.
The cover main body 21 is formed with an opening 20a (see FIG. 4B) that faces the front lower side in a normal state. Further, a front opening 20c (notch-shaped portion) facing the front upper side in a normal state is formed in the front portion of the cover portion 20 (the front portion of the cover main body 21). Although the shape of the front side opening 20c is not particularly limited, as an example, the shape is a parabolic shape (see FIG. 3A).
The cover main body 21 further includes a rear wall portion 21e that covers the rear of the head portion 30 (the rear of the head main body portion 31).

The cap 50 with a liquid dispenser further includes a columnar support portion 54 erected from the upper surface of the rear portion of the mounting portion 52. The support part 54 is arrange | positioned behind the intermediate | middle cylinder 53, for example.
As shown in FIGS. 3B and 4B, the support portion 54 is for supporting the cover portion 20. For example, the cover portion 20 is pivoted on the upper end portion of the support portion 54. A supporting shaft supporting recess 54a is formed.
On the other hand, the lower end of the cover portion 20 is supported by a shaft portion 22 that supports the shaft portion 22 so that the cover portion 20 can swing relative to the support portion 54 by being fitted into the shaft support recess 54a. And a support portion 23 is formed.
More specifically, a concave portion 24 that is recessed forward is formed at the lower rear end of the cover portion 20. The concave portion 24 has a downward inner surface at the upper end, and the support portion 23 projects downward from the downward inner surface of the concave portion 24 and supports the shaft portion 22 at the distal end portion in the projecting direction.
The shaft portion 22 is a round bar-shaped portion whose axial direction faces the width direction of the cover portion 20, and the dimension of the cover portion 20 in the width direction is set larger than that of the support portion 23.
On the other hand, the shaft support recess 54a supports the shaft portion 22 so that the shaft portion 22 can be rotated around the shaft by the shaft portion 22 being fitted therein.
In this way, the cover portion 20 is pivotally supported by the support portion 54 and, by extension, the mounting portion 52 via the shaft support portion constituted by the shaft portion 22 and the shaft support recess 54a.
Note that the height position of the shaft support portion is normally lower than the upper end portion of the head main body 31 as shown in FIGS. 4A and 4B, for example, and preferably the head main body. The height is equal to the lower end of the portion 31 (lower end of the outer cylinder portion 32).

As described above, the cover part 20 and the head part 30 are connected to each other at the action part.
The action part is formed on the inner surface of the cover main body 21 of the cover part 20 and the projection part 33 formed in a state of projecting laterally from the side surface of the outer cylinder part 32 of the head main body part 31 of the head part 30, for example. And a working surface 29a.
More specifically, a cylindrical protrusion 33 that protrudes horizontally toward the left is formed on the left side surface of the outer cylinder portion 32, and the right side surface of the outer cylinder portion 32 faces the right side. Thus, a cylindrical protrusion 33 protruding horizontally is formed.
On the other hand, on the inner surface of the cover main body 21, action surfaces 29 a that engage with the protrusions 33 are formed at portions facing the left and right protrusions 33, respectively. More specifically, a thick part 25 that partially thickens the cover body 21 is formed on the left and right inner surfaces of the cover body 21. A recess 29 that is open toward the inward side is formed. The action surface 29 a is configured by the upper inner surface (that is, the downward surface) of the recess 29.
Therefore, the action part is arranged on the side surface (side) of the head part 30.

As shown in FIGS. 5, 6, and 7, when the cover portion 20 is pressed, the cover portion 20 is pushed from the cover portion 20 to the head portion 30 at the operating portion while swinging around the shaft support portion. The force is transmitted, and the head unit 30 is pushed down relative to the mounting unit 52.
At this time, the action surface 29a moves relative to the protrusion 33 gradually in an arc shape while sliding relative to the protrusion 33. In the process of moving the action surface 29a in this way, the action surface 29a pushes the protrusion 33 downward.

Contrary to the example described here, the protrusion 33 may be formed on the inner surface of the cover body 21, and the action surface 29 a (for example, the recess 29) may be formed on the outer surface of the head portion 30. In this case, the action surface 29 a is pushed downward by the protrusion 33 while sliding with respect to the protrusion 33.
The protruding direction of the protrusion 33 is preferably the horizontal direction, but may be a direction other than the horizontal direction as long as it has a horizontal component.
That is, the action part is formed on the other of the head part 30 or the cover part 20 and the protrusion part 33 formed so as to protrude in a direction having a horizontal component from one of the head part 30 or the cover part 20 and the protrusion. And a working surface 29a that is pushed down by the projection 33 while being slid with respect to the portion 33 or pushed down by the projection 33.

  Further, as shown in FIGS. 4A, 6A, and 7A, a side view of the cap 50 with a liquid agent discharge device viewed in the axial direction of the shaft support portion (the liquid agent discharge container 100 of the shaft support portion). In the side view as viewed in the axial direction, the cover portion 20 covers the action portion. Thereby, when pressing down the cover part 20, it is suppressed that a finger | toe is pinched between the cover part 20 and the head part 30 in an action part.

The arrangement of the action part is not particularly limited as long as the action part is located between the swinging tip part of the cover part 20 and the shaft support part. Since the action portions are arranged in this way, the head portion 30 can be pushed down by utilizing the lever principle by pressing down the portion of the cover portion 20 that is closer to the swinging tip than the action portion. .
For example, when the action part is arranged at an exactly middle position between the shaft support part and the swinging tip part, pressing the head part 30 directly by pressing the swinging tip part of the cover part 20 In comparison, the head unit 30 can be pushed down with a force of about ½.

The liquid agent discharge container 100 further includes a nozzle holding portion 35 provided in the head portion 30 and holding the nozzle portion 40 so as to be able to advance and retreat. The nozzle part 40 slides with respect to the nozzle holding part 35 when moving forward and backward.
More specifically, the nozzle portion 40 is formed in a hollow cylindrical shape, and the nozzle holding portion 35 is formed in a hollow sheath shape that holds the nozzle portion 40 so as to be movable back and forth in the axial direction. For example, the nozzle part 40 and the nozzle holding part 35 are each formed in a cylindrical shape, and the nozzle part 40 is inserted into the nozzle holding part 35.
For example, the nozzle holding part 35 is disposed on the upper side of the head main body part 31. Further, the nozzle holding portion 35 is formed integrally with the head main body portion 31, for example. For example, the front portion of the nozzle holding portion 35 projects forward from the upper surface of the head main body portion 31.
Further, the front portion of the nozzle portion 40 protrudes forward from the front end of the nozzle holding portion 35.
As an example, the axial direction of each of the nozzle part 40 and the nozzle holding part 35 is horizontally arranged. However, the nozzle unit 40 and the nozzle holding unit 35 may be arranged to be inclined with respect to the horizontal plane (for example, arranged in a posture in which the nozzle unit 40 and the nozzle holding unit 35 are inclined downward toward the front).

The nozzle holding part 35 is formed with a liquid supply hole 36 (FIG. 4B) for supplying the liquid 150 from the head main body 31 side to the nozzle part 40 side. More specifically, the liquid agent supply hole 36 supplies the liquid agent 150 from the inside of the inner cylinder portion 34 of the head main body portion 31 to the nozzle portion 40 side.
The nozzle portion 40 is formed with an introduction hole 42 (FIG. 4B) for introducing the liquid agent 150 into the nozzle portion 40 from the liquid agent supply hole 36.
Regardless of the relative position of the nozzle part 40 and the nozzle holding part 35 in the forward / backward direction of the nozzle part 40, the liquid supply hole 36 and the introduction hole 42 are maintained in communication with each other.
The liquid supply hole 36 is formed, for example, so as to vertically penetrate the upper end portion (top surface portion) of the head main body portion 31. The top surface portion of the head main body 31 is closed except for the liquid supply hole 36.
The introduction hole 42 has a larger dimension in the advancing / retreating direction of the nozzle portion 40 than the liquid agent supply hole 36. More specifically, the introduction hole 42 in the advancing / retreating direction of the nozzle part 40 is movable in the advancing / retreating direction. It is set to a dimension that is equal to or greater than the total length of the distance and the dimension of the liquid supply hole 36 in the forward / backward direction.
The introduction hole 42 is disposed, for example, in the lower part of the rear part of the nozzle part 40, and allows the internal space of the nozzle part 40 to communicate with the space below the nozzle part 40.
The rear end portion of the nozzle portion 40 is closed by a rear end closing portion 45. The internal space of the nozzle portion 40 communicates from the introduction hole 42 to the discharge port 41.

In addition, the inner peripheral surface of the nozzle holding portion 35 and the outer peripheral surface of the nozzle portion 40 are respectively in front of the liquid agent supply hole 36 and the introduction hole 42 and behind the liquid agent supply hole 36 and the introduction hole 42. It adheres in a circular manner in the circumferential direction.
That is, in the front seal portion 43 positioned in front of the liquid supply hole 36 and the introduction hole 42, the inner peripheral surface of the nozzle holding portion 35 and the outer peripheral surface of the nozzle portion 40 are closely attached in a circumferential shape in the circumferential direction of the nozzle portion 40. ing. Similarly, in the rear seal portion 44 located behind the liquid agent supply hole 36 and the introduction hole 42, the inner peripheral surface of the nozzle holding portion 35 and the outer peripheral surface of the nozzle portion 40 are circular in the circumferential direction of the nozzle portion 40. It is in close contact.
Thereby, the leakage of the liquid agent 150 from the gap between the nozzle part 40 and the nozzle holding part 35 is suppressed.
It should be noted that the inner peripheral surface of the nozzle holding portion 35 and the nozzle in each of the front seal portion 43 and the rear seal portion 44, regardless of the relative positions of the nozzle portion 40 and the nozzle holding portion 35 in the forward / backward direction of the nozzle portion 40. The outer peripheral surface of the portion 40 is closely attached in a circular shape in the circumferential direction of the nozzle portion 40.

  Furthermore, an opening 37 is formed at the rear end portion of the nozzle holding portion 35 for introducing outside air to the area behind the nozzle portion 40 and inside the nozzle holding portion 35 when the nozzle portion 40 advances. Yes. Thereby, when the nozzle part 40 advances, it can suppress that the area | region behind the nozzle part 40 and the inside of the nozzle holding part 35 becomes negative pressure, Therefore The nozzle part 40 can be advanced with a light force. It becomes possible.

Here, reinforcing ribs 27 are respectively provided on the left and right inner surfaces of the cover main body 21 behind the front opening 20c and in front of the action portion. With the pair of reinforcing ribs 27, the opening area of the front opening 20c is narrowed. The cover unit 20 includes the pair of reinforcing ribs 27 and the cover main body 21. These reinforcing ribs 27 are inclined so as to be positioned forward in the lower part, and also extend to the left and right. The pair of reinforcing ribs 27 are arranged at an equal distance from the shaft support portion.
In the normal state, the lower end position of the reinforcing rib 27 is, for example, lower than the upper end position of the nozzle portion 40. The gap between the pair of reinforcing ribs 27 forms a front slit 71 that allows movement (relative movement) of the nozzle portion 40 and the nozzle holding portion 35 in the gap. The pair of reinforcing ribs 27 face each other in parallel, for example, and the front slit 71 is formed in a straight line shape in a plan view or a front view (see FIG. 3A). The nozzle portion 40 protrudes forward through the front slit 71.
However, instead of the pair of reinforcing ribs 27, one reinforcing rib is provided on the cover body 21, and instead of the front slit 71, an opening for projecting the nozzle portion 40 forward is the one reinforcing rib. It may be formed.
That is, a slit (front slit 71) or an opening for projecting the nozzle part 40 forward is formed in the front part of the cover part 20.

The advance mechanism includes, for example, an advance force receiving projection 46 formed in a state protruding from the side surface of the nozzle portion 40 in a direction having a horizontal component, and an advance force applying surface formed on the cover portion 20. It is configured to include.
More specifically, the left side surface of the nozzle unit 40 is formed with a columnar advance force receiving projection 46 that protrudes horizontally toward the left side, and the right side surface of the nozzle unit 40 has a right side. A cylindrical advance force receiving projection 46 that protrudes horizontally toward the surface is formed.
Further, the advancing force imparting surface is constituted by inner surfaces of guide grooves 27b formed in an arc shape along the longitudinal direction of the opposing surfaces of the pair of reinforcing ribs 27, respectively.
The forward force receiving protrusions 46 on the left and right sides of the nozzle part 40 are respectively disposed in the guide grooves 27b of the reinforcing ribs 27 on the corresponding side. When the cover part 20 is pushed down, the forward force receiving protrusions 46 are arranged in the longitudinal direction of the guide groove 27b. Along the guide groove 27b.
Of the inner surface of the guide groove 27b, the front-facing surface (that is, the rear surface) constitutes a forward force imparting surface. The advancing force application surface advances the advancing force receiving projection 46 while sliding with respect to the advancing force receiving projection 46 when the cover portion 20 is pushed down.
Since the nozzle portion 40 is held by the nozzle holding portion 35 so as to be movable back and forth, the nozzle portion 40 also moves forward when the forward force receiving projection 46 is advanced by the forward force applying surface.

Here, each of the pair of reinforcing ribs 27 is, for example, curved in an arc shape whose distance from the shaft support portion increases as it goes upward. Therefore, the forward force imparting surface is formed in an arc shape in which the distance between the contact portion of the forward force imparting surface with the forward force receiving projection 46 and the shaft support portion becomes longer as the push-down amount of the cover portion 20 increases.
As a result, the forward force receiving projection 46 slides smoothly relative to the forward force applying surface when the cover portion 20 is pressed, as compared with the case where the forward force applying surface is formed in a straight line. ing.

  In addition, the cap 50 with a liquid agent discharger is formed, for example, symmetrically, and the nozzle part 40 and the nozzle holding part 35 are arranged in the center part in the width direction (left-right direction) of the cover part 20 in plan view. (FIG. 3A).

Next, the operation will be described.
In order to discharge the foam from the liquid agent discharge container 100, a pressing operation is performed on the cover unit 20. As a result, the head unit 30 is pressed down by the cover unit 20 via the action unit, and the head unit 30 is pressed down against the bias of the spring body 58. When the head unit 30 is pushed down, foam is discharged from the discharge port 41 of the nozzle unit 40.

At this time, the cover portion 20 swings about the shaft support portion as a fulcrum and gradually tilts forward (see FIGS. 4, 6, and 7). As an example, as illustrated in FIG. 7, in the pressed state, the cover portion 20 is inclined forward until the lower edge of the cover portion 20 is inclined downward toward the front.
Here, when the cover portion 20 is pushed down, the forward force receiving projection 46 is advanced by the forward force applying surface of the guide groove 27b, so that the nozzle portion 40 provided with the forward force receiving projection 46 is the nozzle. It advances while being guided by the holding part 35. Thereby, it is suppressed that the nozzle part 40 is covered with the cover part 20.
The length of the nozzle portion 40 is not particularly limited. As an example, if the nozzle portion 40 does not advance, the nozzle portion 40 may be covered to the extent that the tip of the nozzle portion 40 is covered with the cover portion 20 in a side view when pressed. The part 40 may be formed short.

Further, when the force for pressing the cover part 20 is released, the head part 30 is raised to the normal position in accordance with the biasing of the spring body 58. When the head part 30 is raised, the head part 30 pushes up the cover part 20 via the action part. That is, when the projection 33 pushes up the action surface 29a, the cover 20 swings and the cover 20 returns to the original state.
When the cover portion 20 returns to the original state, the forward force receiving projection 46 is formed by the surface facing the forward force application surface, that is, the rear-facing surface (front surface), of the inner surface of the guide groove 27b. Is retreated. As a result, the nozzle portion 40 provided with the forward force receiving projection 46 is retracted while being guided by the nozzle holding portion 35. Thereby, the nozzle part 40 also returns to the state (normal state) shown in FIG.

According to the embodiment as described above, the liquid agent discharge container 100 moves the nozzle portion 40 to the head main body portion in conjunction with the cover portion 20 swinging with respect to the mounting portion 52 with the shaft support portion as a fulcrum by a pressing operation. An advance mechanism is provided for advancing relative to 31.
Therefore, since the nozzle portion 40 moves forward by pressing the cover portion 20, even if the nozzle portion 40 is formed short so that dripping from the discharge port 41 at the tip portion of the nozzle portion 40 is suppressed, the cover portion 20 can prevent the discharge port 41 at the tip of the nozzle portion 40 from being covered.

In general liquid agent discharge containers, when the nozzle part is shortened to prevent dripping from the discharge port at the tip of the nozzle part, the hand that receives the liquid agent interferes with the shoulder part of the container body. There is a possibility that.
On the other hand, according to this embodiment, since the nozzle part 40 can be advanced, it can suppress that the hand etc. which receive the liquid agent 150 interfere with the shoulder part 12 of the container main body 10, etc.

Further, since the head portion 30 can be pushed down by utilizing the lever principle, the liquid agent discharge container 100 having a relatively large volume of the liquid agent 150 discharged by one discharge operation can be used with a sufficiently light force. By depressing the cover part 20, the head part 30 can be pushed down.
Further, in the liquid agent discharge container 100 of the type that discharges the liquid agent 150 as a foam as in the present embodiment, the head unit for discharging the liquid agent 150 as compared with the liquid agent discharge container of the type that discharges the liquid agent 150 as it is. Although the pressing pressure of 30 increases, it is possible to push down the head unit 30 by pressing the cover unit 20 with a sufficiently light force.
Further, even when the viscosity of the liquid agent 150 is higher than that of a standard one, the head portion 30 can be pushed down by pressing the cover portion 20 with a sufficiently light force.

  In addition, according to the liquid agent discharge container 100, the liquid agent 150 can be discharged from the discharge port 41 while moving the nozzle part 40 forward, so the liquid agent 150 is spread over a linear range corresponding to the operation range of the nozzle part 40. Can be supplied. For example, when the liquid agent 150 is an adhesive, the liquid agent 150 can be applied over a range corresponding to the operation range of the nozzle unit 40. Alternatively, when the liquid 150 is a dishwashing detergent or the like, the liquid 150 can be supplied over a predetermined range on a dishwashing sponge or the like.
