DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing container capable of dispensing a substantially constant amount of a liquid content simply by shaking at the time of use, and in particular, containing and dispensing a liquid cosmetic such as a lotion or milk. The present invention relates to a dispensing container suitable for the above.

[0002]

2. Description of the Related Art Heretofore, a vertical push type or horizontal push type pump container has been known as a container which accommodates a liquid cosmetic so that a suitable constant amount can be poured out during use. This pump container is a container having a mouth-neck portion (opening) at an upper portion and a movable inner plate (piston) at a lower portion, and having a structure in which a vertical push type or a horizontal push type pump is attached to the mouth-neck portion. By pressing the pump from the vertical or horizontal direction,
The liquid cosmetic can be discharged at a fixed amount determined by the capacity of the pump chamber.

A specific configuration of a pump is disclosed in, for example,
In the case of the vertical push type pump disclosed in Japanese Patent Publication No. 0-59405, the pump includes a press-down head with a discharge nozzle and a cap for fixing the same to the mouth and neck of the container. Then, the liquid is discharged from the discharge nozzle by sucking the liquid and further depressing the head. Such a liquid discharge pump is generally provided in a cylinder provided in a cap, a piston mounted in the cylinder, which moves up and down by pressing and releasing a pressing head, and a suction path for liquid from a container to the cylinder. A suction valve is provided, and a discharge valve is provided in a liquid discharge path from the cylinder to the discharge nozzle.

On the other hand, for example, in the case of a horizontal push type pump disclosed in Japanese Patent Application Laid-Open No. Hei 10-24258, a cylinder, a piston moving up and down in the cylinder, and a pump chamber comprising the cylinder and the piston are provided at upper and lower portions, respectively. The push button on both sides of the pump is pressed laterally to move the piston up and down via the pressing force transmitting means to discharge the liquid cosmetic.

[0005]

However, in the pump container having the above structure, the liquid cosmetic can be discharged in a fixed amount determined by the capacity of the pump chamber by pressing the pump from the vertical direction or the horizontal direction. However, since the liquid discharge pump has a structure provided at the mouth and neck and has a structure in which the pressing operation mechanism of the pump is incorporated, there is a problem that the structure is extremely complicated and large. Therefore, it is unsuitable as a water container (bottle) for storing liquid cosmetics such as lotion and milk, without having to equip the mouth and neck with a pump and its pressing operation mechanism,
There is a need for a pour container having a simple structure capable of discharging an internal solution in a substantially constant amount.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to dispose a liquid cosmetic such as a lotion or milk, and to pour out the inner solution almost in a fixed amount simply by shaking at the time of use. Is to provide.

[0007]

In order to achieve the above-mentioned object, a spout container of the present invention is provided with a backless valve for opening and closing a spout at the mouth and neck of the container body, and the pouring container is provided in the container body. Provide a piston slidably toward the outlet,
A weight is displaceably engaged with the piston, and by shaking the container body, the weight collides with the piston to advance the piston, thereby opening the backless valve and discharging the content liquid. (Claim 1).

In the pouring container of the present invention, the weight may be slidably provided on a guide shaft provided on the piston (claim 2), or a hollow chamber is formed in the piston. The weight may be slidably provided in the hollow chamber (claim 3).

In the dispensing container of the present invention, when the container is shaken downward, the weight collides with the piston, thereby obtaining a driving force, and the piston moves forward in the container body toward the spout. Then, the content liquid is pressed. On the other hand, the backless valve opens the spout by the pressed content liquid, whereby the content liquid is discharged from the spout. The backless valve closes the spout at the same time as the end of the dispensing, and prevents the inflow of air into the container, thereby preventing the content liquid from touching the air and deteriorating.

The dispensing container of the present invention has a structure in which the liquid content is dispensed only by adding the operation of shaking the container downward, and is as complicated as a structure equipped with a conventional vertical or horizontal pump. Because it does not have a pump and a pressing operation mechanism,
A dispensing container in the form of a water container (bottle) for containing a liquid cosmetic such as lotion or milk can be obtained with a very simple structure and at a low cost.

7 are provided.

The mouth and neck portion 12 of the container body 10 is closed by a spout cap 20 having a small-diameter spout 21. The spout cap 20 has an inverted U-shaped annular fitting groove 24 composed of an outer peripheral wall 22 and an inner peripheral wall 23, and the fitting groove 24 is fitted to the opening edge 12 a of the mouth and neck portion 12 of the container body 10. At the same time, the opening 12b of the mouth and neck 12 is closed.

On the other hand, the mouth and neck portion 12 of the container body 10 has a partition wall 25 formed in the middle thereof and an opening 2 provided therein.
6, the valve seat 27 is formed. A backless valve 30 is housed in a space between the valve seat 27 and the spout cap 20 so that the spout 21 of the mouth and neck portion 12 can be opened and closed.

As shown in FIG. 2, the backless valve 30 has a base 31 composed of an annular ring fitted into the inner peripheral wall 23 of the spout cap 20 and a disc-shaped seat mounted on the valve seat 27. , And a plurality of elastically deformable connecting cords 33 connecting between the base 31 and the valve 32. In the case of this embodiment, the connecting cord body 33 is made of an elastic material or a flexible material, and is positioned between the annular ring of the base 31 and the valve body 32 so as to intersect spirally or linearly. When the container body 10 is shaken and the operation of shaking the container body 10 is added, the connecting string 33 is elastically deformed as shown in FIG. 3 by the extruded content liquid. That is, the movable valve body 32 is deformed so as to approach the fixed base 31, whereby the valve body 32 is separated from the valve seat 27, and as a result, the backless valve 30 opens the spout 21. .

Next, the cylindrical body 1 of the container body 10 will be described.
2, a piston 40 is slidably disposed toward the spout 21 in the axial direction of the container body 10 as shown in FIG.
In order to enable the piston 40 to be built in, the bottom cover 14 of the container body 10 shown in FIG. 1 is attached by screwing a screw portion 15 protruding from the inner surface thereof to a screw portion 16 inside the opening 13. It is removable. Piston 4
No. 0 is inserted into the body 11 of the container body 10 through the opening 13 with the bottom cover 14 removed, and then the bottom cover 14 is screwed on.

The piston 40 is, as shown in FIG.
It is made of a bowl-shaped member as a whole, has an upper closed wall 41 and a cylindrical peripheral wall 42 around it. The cylindrical peripheral wall 42 of the piston 40 is slightly depressed inward in the radial direction at an intermediate portion in the vertical width direction, whereby the upper edge of the cylindrical peripheral wall 42 with respect to the inner peripheral surface of the body portion 11 serves as an upper sliding contact surface 43 and the lower edge thereof has It is formed so as to act as the lower sliding contact surface 44. This piston 40
The interior of the body 11 is vertically and liquid-tightly partitioned due to the presence of the liquid cosmetic, and a storage space for the liquid cosmetic is formed above the piston 40.

A weight 50 is engaged in the piston 40 so as to be displaceable in the axial direction of the container body 10. This figure 1
3, the guide shaft 45 projects in the axial direction from the back surface of the upper closing wall 41 toward the bottom of the container body 10, and the weight 50 is axially connected to the guide shaft 45. It is slidably inserted. That is, a large-diameter portion 46 for preventing separation is formed at the lower end of the guide shaft 45, and the large-diameter portion 46 is passed over the large-diameter portion 46 so that the through hole 51 of the weight 50 is inserted into the guide shaft 45. In order to facilitate this insertion work, the large diameter portion 46 has
In order to narrow this, the vertical slit 47
The large-diameter portion 46 is formed with a tapered inclined guide surface 48 toward the distal end side.
Further, an inclined guide surface 52 that extends upward is also formed in the through hole 51 of the weight 50.

The weight 50 inserted into the guide shaft 45 can move up and down along the guide shaft 45. As shown in FIG. 2, the lower limit position of the moving range, that is, the stroke length, is a position where the weight 50 abuts on the shoulder 46a of the large diameter portion 46 of the guide shaft 45 and is locked. The position at which the weight 50 contacts the back surface of the upper closing wall 41 is regulated so as to be the upper limit position. Also, in order to allow the moving range of the weight 50 to be long in a limited space, the through hole 51 of the weight 50 is counterbored from below so that the large diameter portion 46 of the guide shaft 45 can pass through. 53 are formed. The lower limit position of the weight 50 is determined so that the weight 50 does not hit the bottom cover 14.

Next, the operation will be described. In the dispensing container 1 having the above-described structure, the content liquid 2 is dispensed in a substantially constant amount simply by adding the operation of shaking the container body 10 downward.

In the backless valve 30, the valve body 32 normally closes the opening 26 of the valve seat 27 by the elastic force of the connecting cord 33 as shown in FIG.
Is closed. The inside of the container body 10 of the pour container 1 is initially filled with the content liquid 2 composed of a liquid cosmetic such as lotion or milk as shown in FIG.
0 is at the lower limit position shown in FIG.

In this state, when the user holds the container body 10 downward and shakes it, the weight 50 collides with the rear surface (upper limit) of the piston 40, or the upper limit position and the large diameter portion 46.
The piston 40 moves forward and backward in the container body 10 toward the spout 21 and presses the content liquid 2. On the other hand, as shown in FIG. 3, the connection cord 33 of the backless valve 30 is elastically deformed by the pushing of the content liquid 2 when shaken, and the movable valve 32 approaches the fixed base 31. To be deformed.
As a result, the valve element 32 separates from the valve seat 27, and as a result, the backless valve 30 temporarily opens the spout 21. After that, the connecting cord body 33 returns naturally by its elastic force. By the cooperative action of the piston 40 and the backless valve 30, a substantially constant amount of the content liquid 2 is discharged.

At the same time as the end of the dispensing, the backless valve 30
Closes the spout 21 to prevent air from flowing into the container body 10. Therefore, an airless liquid cosmetic dispensing container which contains a liquid cosmetic such as a lotion or milk and which can be poured out at an appropriate fixed amount when used can be obtained.

As the content liquid 2 is consumed, the piston 4
0 gradually advances inside the container body 10 toward the spout 21, and finally, the upper closing wall 41 comes into contact with the back surface of the partition wall 25 of the mouth and neck portion 12 and becomes used. In this process, the atmospheric pressure is applied to the back surface of the piston 40 from the air hole 17, so that the disadvantage that the container body 10 is depressed by the negative pressure does not occur.

In the present embodiment, the upper neck wall 41 is attached to the mouth and neck 1 so that the content liquid 2 is completely consumed.
2, a projection 49 corresponding to the inner diameter of
Is penetrated into the space 29 below the partition wall 25 of the mouth and neck portion 12 and the remaining liquid 2 can be pushed out. In addition, the shape of the upper closing wall 41 of the piston 40 is different from the neck 12 of the container body 10 to the shoulder 1.
0a, so that the piston 40 can move to a position where its projection 49 abuts against the back surface of the partition wall 25 of the mouth and neck portion 12, at which point the piston 40 can move. , So that the entire liquid 2 can be pushed out.

Next, FIGS. 4 and 5 show another embodiment of the pouring container of the present invention. FIG. 4 is a side sectional view of the dispensing container, FIG. 5 is a rear view of the piston, and FIG. 6 is an explanatory view of the operation. The pouring container 10 shown in FIGS. 4 to 6 is different from the above embodiment in a structure in which a weight 50 is engaged with a part of the piston 40 so as to be displaceable in the axial direction of the container. That is, in this embodiment, the weight 5
Instead of providing the guide shaft 45 that engages the piston 40, the piston 40 is replaced with a hollow chamber 60 for engaging a weight therein.
And a weight 70 having an outer diameter slightly smaller than the inner circumference of the hollow chamber 60 in the hollow chamber 60.
Are slidably disposed in the axial direction of the container. Since the guide shaft 45 can be omitted from the configurations shown in FIGS. 1 to 3, the structure becomes simpler.

In this embodiment, the hollow body of the piston 40 has an outer peripheral wall 61 corresponding to the skirt of the piston 40.
It is formed by inserting an inner peripheral member 62 having a bottom surface and an open upper portion from the rear side, engaging with a groove 63 and integrating them. The weight 70 can be disposed in the hollow chamber 60 by forming the piston 40 formed as a hollow body having the hollow chamber 60 into a vertically separable structure. When the inner peripheral member 62 is injection-molded with a synthetic resin, a spring 64 serving as a cushioning member for receiving the weight 70 is integrally formed on the bottom surface, that is, the bottom surface of the hollow chamber 60 in a petal shape as shown in FIG. Is formed. The weight 40 is disposed in the hollow chamber 60 inside, and the piston 40 is integrally assembled.
Are housed in the container body 10 as shown in FIG.

The operation of the pouring container 1 shown in FIG.
3 is the same as that of the embodiment of FIG. 3, and the content liquid 2 is almost uniformly dispensed just by adding the operation of shaking the container body 10 downward. That is, when the user shakes the container body 10 downward, the weight 70 is
From the position (lower limit position) supported by the spring body 64 to the upper surface position (upper limit position) of the hollow chamber 60, which is the back surface of the piston 40, and collide, or reciprocate between the upper limit position and the lower limit position While moving, they collide, whereby the piston 40 advances inside the container body 10 toward the spout 21 and presses the content liquid 2. On the other hand, as shown in FIG. 4, the connection cord 33 of the backless valve 30 is pushed out by pushing out the content liquid 2 when shaken.
Are elastically deformed so that the movable valve body 32 approaches the fixed-side base 31. As a result, the valve element 32 separates from the valve seat 27, and as a result, the backless valve 30 moves to open and close the spout 21 temporarily. By the cooperative action of the piston 40 and the backless valve 30, a certain amount of the content liquid 2 is discharged. The backless valve 30 closes the spout 21 at the same time as the end of the pouring, and the container body 1
Prevents air from flowing into the zero.
