BACKGROUND OF THE INVENTION
The present invention relates to a liquid filling method for delami bottles and a refill container used in the method.
[0002]
[Prior art]
A delami bottle is known which includes an outer layer having a shape-retaining property with the mouth and neck raised from the trunk and a flexible inner layer that is peelably laminated on the inner surface of the outer layer. These delami bottles are convenient when storing and using liquids that dislike contact with air, and are often used with a liquid jet pump attached to the mouth and neck, and the inner layer becomes the outer layer as the liquid is discharged. It tries to keep the inner volume that matches the remaining liquid amount by peeling and shrinking.
[0003]
Conventionally, this type of delami bottle is generally discarded as it is after the stored liquid is used, and sometimes the entire pump is discarded. However, in the recent garbage disposal situation, the amount and volume of waste are suppressed as much as possible, and separation processing for recycling is required. Accordingly, the pump is reused as it is, and only the delami bottle is filled with liquid. A new bottle is being replaced. Since the inner layer of the Delami bottle has shrunk after use, the internal volume is extremely reduced even if you try to refill the liquid, it overflows, and refilling over a long time is not impossible but realistic Instead, it was discarded as it was.
[0004]

As shown in FIG. 1, the Delami bottle 1 that is the subject of the present invention has a form in which the mouth and neck portion 4 is erected from the trunk portion 2 through the shoulder portion 3, and has an outer layer a having shape retention and an inner surface of the outer layer a. The inner layer b is peeled and contracted from the outer layer a by sucking out the stored liquid.
[0013]
Such a delami bottle 1 is a used bottle in which the stored liquid is sucked out, and the stored liquid is sucked out by attaching a pump to the neck 4. Explaining an example of the pump without illustrating it, it is fixed to the bottle by a mounting cylinder fitted on the outer periphery of the mouth-and-neck part 4, and a cylinder with a suction valve is suspended in the mouth-and-neck part and biased upward in the cylinder There is a configuration in which the stem is protruded upward from the piston fitted in the state, the ejection head is fitted to the tip, the liquid in the bottle is sucked up by the vertical movement of the head and ejected from the ejection port.
[0014]
When the liquid stored in the bottle is pumped out by such a pump, the inner layer b is peeled off from the outer layer a as the liquid is reduced, and the internal volume corresponding to the residual liquid amount is maintained. At this time, the outside air is introduced into the gap between the inner and outer layers that have been made negative pressure from the vent hole 5 provided in the outer layer. When the stored liquid is used up, for example, as shown in FIG. 1, the inner layer b contracts so that its inner volume becomes almost zero except for the mouth / neck portion 4. It should be noted that the present invention is not intended only for bottles in which the vent hole 5 is provided in the outer layer a of the mouth / neck portion 4 as in the illustrated example, but in a bottle having vent holes in the outer layer of the trunk portion 2 or the shoulder portion. It can cope with it.
[0015]
In the present invention, such a used delamination bottle is filled with liquid, and the refilling of the liquid into the bottle 1 is performed using a refill container. The refill container A used in the method of the present invention is formed of a synthetic resin, an elastomer, or the like, and includes a mouth part A1 and a liquid storage part A2.
[0016]
The mouth portion A1 is fitted to the mouth / neck portion 4 in a liquid-tight and detachable manner. The refill container A is tightly connected to the bottle 1, and the filling liquid 6 in the liquid storage portion A2 is press-fitted into the bottle 1. As long as the structure is possible, various forms can be adopted.
[0017]
The liquid storage part A2 can adopt various forms as long as it can store the liquid and can discharge the liquid through the mouth part A1, for example, a cylindrical one as shown in FIG. 5 may be in the form of a bag as shown in FIG. Further, as shown in FIG. 1, it may be formed integrally with the mouth portion A1, or may be formed separately from the mouth portion A1 as shown in FIG.
[0018]
The refill container A of FIG. 1 includes a liquid storage portion A2 having a shoulder portion 8 extending from the upper end edge of the thin-walled cylindrical body portion 7, and the mouth portion A1 is erected integrally from the upper end of the shoulder portion 3. In addition, a horizontal annular seal surface 9 is formed on the outer peripheral portion of the base end portion of the mouth portion A1 at the upper end portion of the upper surface of the shoulder portion 8, and a seal protrusion 10 is provided above the lower portion of the outer periphery of the mouth portion A1. Each has a thread 11 for projecting a cap (not shown). And when not in use, for example, a cap is screwed into the mouth A1 and stored.
[0019]
In the method of the present invention, using such a refill container A, the filling liquid 6 in the liquid storage part A2 is press-fitted, so that the air between the inner and outer layers is discharged while being discharged from the vent hole 5 provided in the outer layer a. The inner layer b is expanded and filled with a liquid. Then, as shown in FIG. 1, the refill container A with the cap removed is connected to the bottle 1 in an inverted state. In this case, for example, after connecting both the neck and neck 4 inner periphery of the inverted bottle 1 to the outer periphery of the mouth A1 of the refillable container A in the upright state, the state shown in FIG. Can be.
[0020]
Specifically, the filling method will be described. When the liquid storage part A2 is squeezed from the state of FIG. 1, the filling liquid 6 in the liquid storage part A2 is pressed into the bottle 1 and the inner layer b is expanded. At that time, the air outside the inner layer b is discharged to the outside through the vent hole 5. Then, the filling liquid 6 is sequentially pressed into the bottle 1 and the filling is completed as shown in FIG.
[0021]
As shown in FIG. 2, the refilled bottle 1 does not completely adhere to the inner layer b, but functions sufficiently to be used again with the pump attached. Therefore, if such a refill container A is prepared, it can be reused many times each time the stored liquid is used up. Incidentally, pressing method of the liquid storage portion A2 in this case is not limited to squeezing the body portion 2 from both sides as shown in FIG. 2, as shown in FIG. 4, there in a way that will is folded into the interior while pressing the bottom May be. In addition, when the liquid to be filled has a low viscosity and high fluidity, the liquid can be filled with its own weight without necessarily pressing the liquid storage portion A2. However, in this case, a considerable amount of time is required. Therefore, in such a case, it is possible to configure the liquid storage portion to have a thickness that is difficult to squeeze.
[0022]
FIG. 5 shows an example in which the method of the present invention is performed using a refill container A of another form. The refill container A in this embodiment has a mouth part A1 and a liquid storage part A2 as separate members. They are formed and integrated. The mouth portion A1 is configured such that a flange 13 protrudes from the middle portion of the outer peripheral longitudinal direction of the cylindrical peripheral wall 12 and its upper surface is an annular seal portion 9, and is in pressure-tight contact with the upper surface of the mouth and neck portion 4. Further, a seal protrusion 10 is provided on the inner surface b of the inner periphery of the mouth and neck portion 4 above the flange 13 so as to press the outer peripheral edge, and further a screw 11 for screwing a cap (not shown) thereon. Around. Further, a pair of flat projections 14 are provided on the outer surface of the peripheral wall 12 below the flange 13. Further, the liquid storage portion A2 has a bag shape, and each plate-like protrusion 14 and the peripheral wall 12 at the same position are inserted into the upper end opening portion, and are integrated by appropriate fixing means such as fusion.
