This discharge container is composed of a main container body 2, a partition member 10, an inner plug member 20, a cap 30, and an operating member 60. However, these structures can be modified as appropriate.
Each of these members can be made of, for example, a synthetic resin material.

The main container body 2 is a cylindrical member with a bottom, and the lower surface of a straight cylindrical peripheral wall 6 is closed with a bottom wall 4 . An upper opening A2 is formed at the upper end of the cylinder peripheral wall 6, and lower openings A1 are formed at appropriate locations (in the illustrated example, two locations) on the bottom wall 4.
The lower opening A1 is a ventilation hole, and has the role of transmitting air pressure generated when an elastic deformation section 64 (described later) is pressed to the inner plate 10A (described later). The shape, size, and number of the lower openings A1 can be arbitrarily designed as long as they function as ventilation holes.
In the illustrated example, the peripheral end of the bottom wall 4 is connected to the lower end of the vertically long cylinder peripheral wall 6, and a cylindrical extension wall 8 having the same diameter as the cylinder peripheral wall 6 extends downward from this peripheral end. It is being extended.
In the illustrated example, a first retaining protrusion q1 for preventing the outer cylindrical portion 62a, which will be described later, from coming off, is provided on the outer surface of the extension wall portion 8, and an outer peripheral wall 34, which will be described later, is provided on the upper outer surface of the cylindrical peripheral wall 6. A second retaining protrusion q2 is formed to prevent the member from coming off. Further, a rib 7 is provided around the lower side of the second retaining protrusion q2.

The partition member 10 is arranged within the main container body 2. The role of this partition member 10 is to partition at least a part of the space inside the main container body 2 into a contents storage chamber B that is blocked from the lower opening A1.
The partition member 10 of this embodiment is formed as an inner plate 10A that is fit into the inner surface of the lower part of the cylinder peripheral wall 6 so as to be able to rise as shown in phantom lines in FIG. This inner tray 10A divides the inside of the main container body 2 into a lower air chamber C and an upper content storage chamber B.
The air chamber C is an air reservoir for storing high-pressure air therein, and has the role of expanding and reducing the volume of the content storage chamber B by pressure feeding of air from a pressing means P, which will be described later. The air chamber C communicates only with the inside of the operating member 60 via the lower opening A1.
The contents storage chamber B communicates with the inside of the upper opening A2, and also communicates with the discharge port 42, which will be described later, through the inside of the upper opening A2.
The inner plate 10A has a sliding member 14 attached to the peripheral end of the horizontal wall portion 12, and this sliding member 14 is brought into sliding contact with the inner surface of the cylindrical peripheral wall 6. Further, a fitting convex portion 12a is formed at the center of the illustrated horizontal wall portion 12. This fitting convex portion 12a is formed so as to be housed in a stopper cylinder portion 26a, which will be described later, when the inner plate 10A is raised to the upper limit position as shown by the imaginary line in FIG. Thereby, it is possible to reduce the amount of unused contents.

In this embodiment, the inner plug member 20 is formed of a fitting cylinder portion 22, a flange-like wall portion 24, and an inner plug 26.
The fitting cylindrical portion 22 is fitted into the upper end portion of the cylindrical peripheral wall 6. A flange portion 22a is attached to the upper end of the fitting cylindrical portion 22, and this flange portion 22a is locked to the upper end surface of the cylindrical peripheral wall 6.
The flange-like wall portion 24 projects inward from the lower end of the fitting cylinder portion 22 .
The inner plug 26 is raised from the inner circumferential end of the flange-like wall portion 24, and is formed to be able to be fitted into the inside of a discharge cylinder 44, which will be described later, in a liquid-tight manner.
A valve hole 27 is opened in the upper surface of the inner stopper 26 and can be closed with a valve body 48, which will be described later.
The illustrated inner stopper 26 has a stopper cylinder part 26a that stands up from the flange-like wall part 24, and a valve cylinder part 26c projects upward from the upper end of the stopper cylinder part 26a via an inward flange 26b. The inner circumferential surface of the valve cylinder portion 26c is formed into a tapered surface with a large diameter at the upper end. The cylindrical hole of this valve cylinder portion 26c is the aforementioned valve hole 27.

In this embodiment, the cap 30 is formed of a cap body 32 and a lid body 52. However, this structure can be modified as appropriate.
In this embodiment, the cap main body 32 has an outer circumferential wall 34 fitted to the upper outer surface of the cylinder circumferential wall 6, and a cap top wall 36 is attached within the upper end of the outer circumferential wall 34.
An inner circumferential wall 38 that is fitted into the inner surface of the fitting cylinder portion 22 is suspended from the back surface of the cap top wall 36 .
An engaging portion 40 is raised from the upper surface of the outer edge of the cap top wall 36 . This engaging portion 40 is fitted onto a lower end portion of the inner surface of a lid peripheral wall 54, which will be described later.
Further, a discharge port 42 is formed in a part of the cap top wall 36 (in the illustrated example, the center part). In this embodiment , a discharge tube 44 is formed that vertically penetrates the cap top wall 36, and the discharge port 42 is opened inside the discharge tube 44.
The illustrated discharge cylinder 44 has an upper half cylinder part 44a that stands up from the cap top wall 36, and a lower half cylinder part 44b that hangs down from the cap top wall 36. The lower part of the lower half cylinder part 44b is fitted onto the outer surface of the stopper cylinder part 26a.
In the illustrated example, the lower half-cylindrical portion 44b is formed to have a larger inner diameter than the upper half-cylindrical portion 44a. A plurality of elastic support pieces 46 are provided vertically from the lower end of the upper half cylinder part 44a into the lower half cylinder part 44b, and a pedestal-shaped valve body 48 is attached to the lower end of the elastic support pieces 46. This valve body 48 is fitted into the valve hole 27.
The elastic support piece 46 has a role as a spring portion, and presses the valve body 48 into the valve hole 27 with a sufficient pressure force.
A seal valve V is formed by the valve body 48 and the valve hole 27.
The lid body 52 is integrally connected to the cap body 32 via a hinge 50, and is formed so that the upper surface of the cap top wall 36 can be opened and closed.
The lid body 52 in the illustrated example has a lid peripheral wall 54 having approximately the same diameter as the outer peripheral wall 34, the lid peripheral wall 54 is hingedly connected to the upper end of the outer peripheral wall 34, and the upper end of the lid peripheral wall 54 The plates 56 are connected. A plug-like protrusion 57 is provided vertically from the back surface of the top plate 56. This plug-like protrusion 57 is fitted into the upper end of the discharge cylinder 44 .
A finger hook 58 is attached to the lower end of the lid circumferential wall 54, located on the opposite side of the hinge 50.

The operating member 60 has a ring-shaped fitting part 62 fitted to the extension wall part 8, and an elastic deformation part 64 that bulges downward from the lower end of the ring-shaped fitting part 62. This operating member 60 and the lower part of the main container body 2 in which the lower opening A1 is formed in the bottom wall 4 form a pressing means P.

In the illustrated example, the ring-shaped fitting part 62 is formed in an outer cylindrical part 62a and an inner cylindrical part 62b that are connected at the lower end side, and is arranged so that the extension wall part 8 is sandwiched between these two cylindrical parts. is formed. The lower end surface of the extension wall portion 8 is abutted against a branch point of the outer cylinder portion 62a and the inner cylinder portion 62b.
However, this structure can be modified as appropriate. For example, one of the inner cylindrical part and the outer cylindrical part may be omitted, and a single cylindrical part fitted onto the inner or outer surface of the extension wall may be formed.

The elastic deformation part 64 bulges downward from the ring-shaped fitting part 62, and is formed so that it can be elastically compressed by pushing a finger contact surface part 66 formed in a part thereof upward with a finger. .
Although the elastic deformation portion 64 in the illustrated example is formed into a bowl-shaped elastic dome, this structure can be modified as appropriate. For example, it may be formed into a conical elastic dome or a cylindrical body with bellows.
An outside air introduction hole 68 is bored at a proper location of the elastic deformation section 64 (in the illustrated example, the central part of the shape viewed from below), and the finger contact surface section 66 is formed around this outside air introduction hole 68. are doing. Note that the size of the outside air introduction hole 68 is preferably set to a size that allows the user to close it with the tip of one finger.
According to this structure, as shown by the imaginary line in FIG. 2, when the user places his or her finger on the finger-applying surface portion 66, the outside air introduction hole 68 is inevitably closed. Therefore, even if an outside air introduction valve (check valve) is not provided in the outside air introduction hole, the pressure inside the elastic deformation section 64 can be increased by pushing the finger contact surface section 66.
However, this configuration is only a preferred embodiment of the present invention, and for example, a structure in which an outside air introduction hole is opened at a location other than the finger rest surface portion and a check valve is provided in this outside air introduction hole is also a technique of the present invention. fall within the target range.
In the illustrated example, the finger contact surface portion 66 is formed into an annular protrusion that protrudes downward compared to the outer dome portion. By doing this, the location where the finger is applied becomes clear in appearance, and the inconvenience that the pressing means P does not function due to the user applying the finger to a location that is deviated from the location where the outside air introduction hole 68 is formed is avoided. can do.
However, this structure can be modified as appropriate; for example, the finger rest surface portion 66 may be shaped to be smoothly continuous with the outer dome portion. In this case, a mark indicating the position of the finger rest surface 66 may be formed using, for example, letters or colors.

From the state shown in FIG. 1, the lid body 52 is turned over in the opening direction by placing a finger on the finger hook 58, and then the entire discharge container is turned over in the vertical direction as shown in FIG.
Then, when a finger is placed on the finger contact surface portion 66 and pushed downward, the elastically deformable portion 64 is elastically compressed and the internal pressure is increased, so that the air inside the elastically deformable portion 64 is compressed, as shown in FIG. enters the air chamber C through the lower opening A1.
Then, the pressure inside the air chamber C becomes high, so the inner plate 10A slides inside the cylinder circumferential wall 6 and is pushed toward the cap 30, and the air chamber C expands and the content storage chamber B is expanded. Reduce volume. As a result, the pressure inside the contents storage chamber B becomes high, so the seal valve V opens and the contents are discharged from the discharge port 42 via the seal valve V.
When the finger contact surface portion 66 is released, the negative pressure in the content storage chamber B is released and the seal valve V is closed. This makes it possible to seal the discharge port 42 after discharging the contents, and prevents external air from easily entering the air storage chamber B.
Further, in order for the elastically deformable portion 64 to recover elastically, the inside of the elastically deformable portion 64 is made negative pressure, and outside air is sucked into the elastically deformable portion 64 through the outside air introduction hole 68 .
When the discharge container is returned to the upright state from this state and the lid 52 is closed, the state shown in FIG. 1 is returned.

By sealing the discharge port 42 and blocking air after discharging the contents, when the discharging operation is repeated, the inner tray 10A moves forward inside the main container body toward the cap, and the inner tray 10A can be used without leaving any contents behind. can. Since the contents do not come into contact with air, they can be used fresh.

Hereinafter, a discharge container according to another embodiment of the present invention will be described. In these descriptions, explanations regarding the same configurations as in the first embodiment will be omitted.

4 and 5 show a discharge container according to a second embodiment of the present invention. In this embodiment, the partition member 10 is an inner container body 10B that is removably laminated on the inner surface of the bottom wall 4 and the cylinder peripheral wall 6 of the main container body 2, and is formed to be collapsible by creating a negative pressure inside. .
Further, the main container body 2 is a rigid outer container body. That is, this embodiment employs a so-called delamination container structure in which the outer container body and the inner container body are laminated in a separable manner.
By doing so, the assembly work of the discharge container can be facilitated.
The upper end portion of the inner container body 10B is held between the upper end portion of the cylinder peripheral wall 6 and the fitting cylinder portion 22 as a fixed end portion.
In this embodiment, the lower end portion of the inner container body 10B is clamped and fixed to a pinch-off portion of the bottom wall of the main container body. However, this structure can be modified as appropriate.
In the preferred illustrated example, the extension wall portion 8 is omitted from the structure of the main container body 2 of the first embodiment, and the lower portion of the cylindrical peripheral wall 6 is formed into a small outer diameter portion 6a.
Further, the ring-shaped fitting portion 62 of the operating member 60 is formed into a single fitting cylindrical portion, and this fitting cylindrical portion is fitted into the small outer diameter portion 6a.
The bottom wall 4 is provided with a lower opening A1 having a size that does not interfere with the stacking of the inner container bodies 10B.
These lower openings A1 can be provided in pinch-off parts of the bottom wall 4 of the main container body.
In the pinch-off portion, the inner container body and the outer container body are not completely adhered to each other, and a lower opening A1 (slit) is formed due to bottom cracking and delamination of the seal portion.
The pinch-off portion is a rib that protrudes downward on the parting line of the bottom wall 4, and the pinch-off portion is a rib that is provided to protrude downward on the parting line of the bottom wall 4, and the pinch-off portion is a rib that is provided to protrude downward from the parting line of the bottom wall 4. The structure is such that air is introduced into the

Further, in this embodiment, a hanging cylinder part 28 is formed by extending the stopper cylinder part 26a of the inner stopper 26 downward. In the illustrated example, the hanging cylindrical portion 28 is provided with a slit 28a extending upward from the lower end of the cylindrical wall. Thereby, it is possible to reduce the amount of contents left inside the inner container body 10B.

In the above configuration, when the lid body 52 is opened from the state shown in FIG. 4, and then the finger is placed on the finger contact surface portion 66 and pushed in as shown by the arrow as shown in FIG. 5, the elastic deformation portion 64 is compressed. be done.
Therefore, the air in the elastically deformable portion 64 is forced into the main container body 2 through the lower opening A1, so that the inner container body 10B is separated from the outer peripheral side of the bottom wall.
As a result, an air pocket (air chamber) C is formed between the inner container body 10B and the main container body 2, and the inner container body 10B is peeled off from almost the entire cylinder peripheral wall 6 using this air pocket as a passage.
This reduces the volume of the inner container body 10B, so the seal valve V opens and the contents are discharged from the discharge port 42.
