Description

The present invention relates to a fluid discharger that discharges a fluid contained in a flexible packaging bag by a discharge member.

Conventionally, rigid plastic packaging containers have generally been used in products that handle various fluids such as cosmetics, shampoos, soaps, and perm solutions. And, in consideration of the environment for the earth, even after using all the fluid from the plastic packaging container, the plastic packaging container is maintained without being discarded, and it is made into a flexible packaging bag for refilling. The contained fluid is refilled in plastic packaging.

However, in this case, since the fluid comes into contact with air at the time of refilling or after refilling, there is a risk that the fluid will deteriorate. In addition, if the plastic packaging container is used for a long period of time, fluid adheres to the packaging container, mold grows, and wear occurs, and the appearance of the packaging container is gradually impaired. It wasn't always pleasant for me.

Therefore, in recent years, it has begun to be considered to use a flexible packaging bag as a main body of a product instead of using it as a refill. Specifically, a discharge member is provided in the flexible packaging bag, and the discharge member discharges the fluid without injecting air into the inside of the packaging bag. According to this, since the fluid does not come into contact with air at all or hardly, deterioration of the fluid can be prevented. Further, after all the fluid is discharged from the packaging bag, it is sufficient to replace it with a new packaging bag, so that a new and clean state can always be maintained.

However, in the case of a flexible packaging bag, since air does not enter the inside of the packaging bag in the process of discharging the fluid contained in the packaging bag by the discharge member, the walls of the packaging bag are in close contact with each other. Finally, there was a problem that the passage of the fluid was blocked around the suction port of the discharge member, and the fluid remained inside the packaging bag (particularly at the bottom).

Therefore, conventionally, a box-shaped container for holding a flexible packaging bag has been proposed so as to be deformed while preventing the wall surfaces of the packaging bag from coming into close contact with each other (Patent Document 1). , 2). However, in this case, the box-shaped container had to be used continuously, and in the end, the box-shaped container became dirty and the appearance was spoiled.

On the other hand, in the field of food, flexible packaging bags are often used, and in order to solve the problem of obstructing the fluid passage in the packaging bag, not only the tip of the spout or spout but also the tip of the spout is used. Various ideas have been attempted, such as forming a plurality of suction ports on the body portion (see Patent Documents 3 to 6). However, since all of these structures are structures in which the packaging bag is compressed by human hands and the fluid is sucked by the human mouth, the fluid is discharged by the discharge member without injecting air into the packaging bag. It was difficult to apply to the structure.

The packaging bag 1 is a so-called standing pouch composed of a pair of front and back wall members 11 and 11 facing each other and a bottom member 12 provided on the bottom of the wall members 11 and 11. In this packaging bag 1, the upper ends of the wall surface members 11 and 11 are heat-sealed with each other except for the female connector 2, and the side edges of the wall surface members 11 and 11 are heat-sealed with each other. The lower end portion of 11 and the peripheral edge portion of the bottom surface member 12 are heat-sealed, and the fluid accommodating portion 13 is formed with a space surrounded by a pair of front and back wall surface members 11, 11 and the bottom surface member 12.

The wall surface member 11 and the bottom surface member 12 are made of a flexible synthetic resin sheet material, and a sealant layer is formed on at least one surface thereof. The configuration and thickness of the wall surface member 11 and the bottom surface member 12 are not particularly limited, and a design having oxygen barrier property, water vapor barrier property, and the like can be appropriately made according to the properties of the contained fluid.

The female connector 2 includes a female member 21 which is a main body and a plug 22 which is detachably engaged with a tip portion of the female member 21.

The female member 21 is fixed so that its upper portion is sandwiched between the wall surface members 11 of the packaging bag 1 and is formed so as to extend toward the bottom of the packaging bag 1. The female member 21 has a length for arranging the plug 22 at a predetermined position in the fluid accommodating portion 13 of the packaging bag 1 when connected to the male connector 32 of the discharge member 3 as described later. There is.

Further, the female member 21 has a conduction path 21a having openings at both ends extending in the axial direction inside, and a male connector 32 of the discharge member 3 is inserted from the base end opening 21b at the start of use to guide the female member 21. After the male connector 32 is completely inserted through the passage 21a, the male connector 32 of the discharge member 3 protrudes from the tip opening 21c.

Further, the female member 21 is provided with one fin member 21d extending in the axial direction on each of the left and right peripheral surfaces.

The plug 22 is detachably engaged with the tip end portion of the female member 21 as described above. Before using the fluid discharge tool, the plug 22 is engaged so as to fit into the tip of the female member 21 and closes the tip opening 21c of the female member 21. Further, at the start of use of the fluid discharge tool, as shown in FIGS. 4 to 6, the plug 22 is engaged so as to fit into the tip of the male connector 32, and is accompanied by the insertion of the male connector 32. It comes off from the tip of the female member 21 and opens the tip opening 21c of the female member 21. Further, after using this fluid discharge tool, as shown in FIGS. 1 to 3, the plug 22 is engaged so as to fit into the tip of the female member 21 as the male connector 32 is pulled out, and the female member 21 is engaged. The tip opening 21c of the member 21 is closed again.

Further, when the plug 22 comes off from the tip end portion of the female member 21 due to the insertion of the male connector 32 at the start of use of the fluid discharge tool, the height direction of the fluid accommodating portion 13 of the packaging bag 1 It is arranged at any position from the middle portion to the bottom portion (in the present embodiment, the position of the central portion in the height direction of the fluid accommodating portion 13 of the packaging bag 1). The action and effect of the position of the plug 22 will be specifically described in the operation described later.

The discharge member 3 includes a pump portion 31 as a main body and a male connector 32 provided below the pump portion 31.

The pump unit 31 is a known pump mechanism including an upper pump unit 31a and a lower pump unit 31b, and the upper pump unit 31a is moved up and down with respect to the lower pump unit 31b to perform a piston operation to the lower pump unit 31b. The fluid is sucked using the principle that the inside of 31 becomes a vacuum.

The male connector 32 is formed so that the upper end portion is fixed to the lower portion of the lower pump portion 31b and extends in the axial direction of the pump portion 31. The male connector 32 has a length for the plug 22 to be arranged at a predetermined position in the fluid accommodating portion 13 of the packaging bag 1 when connected to the female connector 2 as described later.

Further, the male connector 32 is formed in a cylindrical shape according to the inner surface shape of the conduction path 21a of the female member 21, and when connected to the female connector 2, at least one of the conduction paths 21a of the female connector 2. It adheres to the portion and maintains the airtightness of the fluid accommodating portion 13 of the packaging bag 1.

Further, in the male connector 32, a plurality of suction ports 32a are formed at the tip portion thereof, and a flow passage (not shown) extending in the axial direction is formed inside. Therefore, when this fluid discharge tool is used, when the upper pump portion 31a is pistoned with respect to the lower pump portion 31b in the pump portion 31, the fluid contained in the fluid accommodating portion 13 of the packaging bag 1 is released. It is sucked from the suction port 32a of the male connector 32, passes through the flow path of the male connector 32, and then is discharged to the outside from the discharge port 31c of the pump unit 31.

Next, a method of using this fluid discharge tool will be specifically described.

Before the start of use of this fluid discharge tool, the male connector 32 of the discharge member 3 and the female connector 2 of the packaging bag 1 are not yet connected, so that the plug 22 is fitted into the tip of the female member 21. The tip opening 21c of the female member 21 is closed.

At the start of use of this fluid discharge tool, as shown in FIGS. 4 to 6, in order to connect the male connector 32 of the discharge member 3 and the female connector 2 of the packaging bag 1, the conduction path 21a of the female member 21 When the male connector 32 is inserted from the base end opening 21b, the plug 22 that is engaged so as to fit the tip of the female member 21 is engaged so as to fit the tip of the male connector 32. With the insertion of the male connector 32, the female member 21 is disengaged from the tip end portion, and the tip end opening 21c of the female member 21 is opened. At this time, the tip of the male connector 32 protrudes from the tip opening 21c of the female member 21, and the suction port 32a of the male connector 32 is exposed to the fluid accommodating portion 13.

When the upper pump portion 31a is pistoned with respect to the lower pump portion 31b in the pump portion 31 when the fluid discharge tool is used, the fluid contained in the fluid accommodating portion 13 of the packaging bag 1 becomes male. It is sucked from the suction port 32a of the mold connector 32, passes through the flow passage of the male connector 32, and then is discharged to the outside from the discharge port 31c of the pump unit 31.

When the fluid is discharged from the fluid accommodating portion 13 of the packaging bag 1 using the discharge member 3 in this way, air does not enter the inside of the packaging bag 1, so that the wall surface members 11 and 11 of the packaging bag 1 come together. There is a risk that they will come into close contact with each other and eventually block the fluid passage around the suction port 32a of the male connector 32 of the discharge member 3.

However, in the present invention, when the plug 22 comes off from the tip end portion of the female member 21 due to the insertion of the male connector 32 at the start of use of the fluid discharge tool, the plug 22 is in the fluid accommodating portion 13 of the packaging bag 1. It is arranged at any position from the middle portion to the bottom portion in the height direction (in the present embodiment, the position of the central portion in the height direction of the fluid accommodating portion 13 of the packaging bag 1), whereby the wall surface member of the packaging bag 1 is arranged. The packaging bag 1 is deformed while preventing the 11s and 11s from coming into close contact with each other. Therefore, a fluid passage is secured around the suction port 32a of the male connector 32 of the discharge member 3, and the fluid contained in the flexible packaging bag 1 is easily and surely discharged without injecting air. be able to.

Further, in the present embodiment, since the fin member 21d also prevents the wall surface members 11 and 11 of the packaging bag 1 from coming into close contact with each other, a fluid passage is provided around the suction port 32a of the male connector 32 of the discharge member 3. It can be secured even more.

Then, after using the fluid discharge tool, the male connector 32 is pulled out from the conduction path 21a of the female member 21 in order to disconnect the male connector 32 of the discharge member 3 and the female connector 2 of the packaging bag 1. Then, the plug 22 engages with the female member 21 so as to fit into the tip of the female member 21 as the male connector 32 is pulled out, and closes the tip opening 21c of the female member 21 again.

After that, the used packaging bag 1 is discarded, a new packaging bag 1 is prepared, and the discharge member 3 is attached to the packaging bag 1 in the same manner as described above.

In the present embodiment, the plug 22 is engaged so as to fit into the tip of the male connector 32 at the start of use of the fluid discharge tool, but the plug 22 does not fit into the tip of the male connector 32. It may be engaged in a manner that is simply extruded.

Further, after using this fluid discharge tool, the plug 22 engages with the tip end portion of the female member 21 as the male connector 32 is pulled out, and the tip end opening 21c of the female member 21 is closed again. However, it is not necessary to pull out only the male connector 32 as it is and close the tip opening 21c of the female member 21 again.

Next, examples of the present invention will be described with reference to FIGS. 7 and 8.

In this embodiment, an experiment was conducted to identify the optimum position of the plug 22 in the fluid storage portion 13 of the packaging bag 1.

As a test sample, as shown in FIG. 8, packaging bags 1 (stunching pouches a to k) having different heights were prepared. Each of these packaging bags 1 has a shape as shown in FIG. 7, and has a polyethylene terephthalate film (thickness 12 μm) as the outermost layer, an aluminum foil (thickness 7 μm), a polyamide film (thickness 15 μm), and an innermost layer as intermediate layers. It is composed of a film produced by laminating a linear low-density polyethylene film (thickness 100 μm). Further, the fluid accommodating portion 13 of each packaging bag 1 was filled with a viscous treatment liquid in the filling amount shown in FIG.

As a test method, a discharge member 3 that discharges 3 cc by one push operation is attached to each packaging bag 1a to 1k, and the push operation is performed three times every 30 seconds to discharge the fluid from the discharge member 3. When the amount becomes 1 cc or less per three push operations, the weight of the packaging bag 1 is measured, and as shown in FIG. 8, the residual rate of the fluid remaining in the fluid accommodating portion 13 of the packaging bag 1 is determined. Calculated. Further, since the low residual rate of the fluid means that the passage of the fluid can be secured by that much, an attempt was made to determine the commercial value based on the residual rate of the fluid.

According to this test, it was found that the plug 22 should be arranged at the position represented by the following equation. This C / M indicates the ratio of the height of the plug 22 to the fluid accommodating portion 13 of the packaging bag 1.
[1] 0.36 <C / M <1.00
C: Distance from the upper end surface 13a of the fluid accommodating portion 13 of the packaging bag 1 to the tip end portion of the plug 22 M: Distance from the upper end surface 13a to the lower end surface 13b of the fluid accommodating portion 13 of the packaging bag 1.

Further, it was found that the plug 22 is preferably arranged at the position represented by the following equation.
[2] 0.38 <C / M <1.00

Further, it has been found that it is more preferable that the plug 22 is arranged at the position represented by the following equation.
