[Industrial application]

 The present invention relates to a viscous liquid dispensing container that blocks the influence of air on the contents and facilitates manufacturing and filling and extracting of the contents.

[0002]

[Prior Art]

 Conventionally, as a viscous liquid dispensing container for cosmetics, foods, etc., there is an elastic squeeze tube dispensing package represented by JP-A-1-139370. This dispensing package contains the viscous liquid that is the product inside, and when a certain amount of this is dispensed, external air flows into the package, but at this time the contact between the air and the viscous liquid is cut off. At the same time, it is said that it facilitates the introduction of external air during extraction.The contents consist of a tubular inner container and an elastic outer container, and the flexible throttling tube of the inner container is Is fixed to the inner surface of the elastic outer container by heat welding or the like, and the lower half of the tube is inverted into the upper half so that the viscous liquid contained inside can be extracted. Then, in order to extract the viscous liquid contained in this inner container, there is an air escape limiting means, that is, an air introducing portion provided with a check valve, at the bottom of the outer container, and a suck back valve is provided at the head. It is provided so that only the viscous liquid inside is extracted to the outside, and then the outside air does not flow into the inner container due to the restoration of the outer container.

[0003]

[Problems to be solved by the device]

 However, in the dispensing package typified by such an official gazette, as can be understood from the illustrated contents, the number of parts is large, the cost is high, and the manufacturing is difficult. .. Especially, since the middle point of the thin film laminated tube is adhered to the inner surface of the outer container by heat welding or the like, not only the fitting operation of the inner and outer containers is difficult, but also the heat welding of the middle point is performed. At times, the tube may be damaged or broken, causing defective products. In addition, since the inner container is made of a thin film material such as a laminated tube, it is rigid and extremely difficult and inefficient at the time of fitting to the outer container. It leads to cost-up in the process. The present invention proposes a container in which the above-mentioned problems of the related art, in particular, manufacturing is facilitated and filling and extraction of the contents into the inner container are facilitated.

[0004]

[Means for Solving the Problems]

 The object of the present invention is to allow the opening in the direction of the extraction port at an appropriate position of the extraction path which is composed of a head and a shoulder, and the head has an extraction port at one end and an introduction port at the other end. Check valve, and a viscous liquid dispensing part having an outer mounting part at the shoulder and an inner mounting part at the lower end of which a plurality of leg pieces are installed, and its mouth end at the shoulder part. A tubular inner container that holds the viscous liquid that is fixed to the inner mounting part of the leg and that is mounted in relation to the inner or outer surface of the leg piece, and the outer container of the inner container and the upper end of the shoulder part. This is achieved by a viscous liquid dispensing container consisting of an elastic outer container that is fixed to the outer mounting part and holds a check valve that can take in external air unidirectionally inside in a proper place.

[0005]

[Action]

 The viscous liquid dispensing container according to the present invention has a tube-shaped inner container inside and an elastic outer container outside, and an intervening space is provided between the two containers. If the elastic outer container is pressurized with the viscous liquid filled in, the air between the inner container and the outer container does not flow out to the outside due to the check valve installed in its place, and That is, pressure is applied in the direction of extracting the viscous liquid from the extraction port of the head to the outside. Therefore, the viscous liquid enters the extraction channel from the inlet of the head and is extracted from the extraction port of the tip to the outside.

At this time, if the elastic outer container is released, the container naturally tries to restore to its original shape. However, although external air normally flows in from the extraction port of the head, the extraction passage is in the proper position. As a result of being blocked by the non-return valve provided on the inside, the viscous liquid adhering to the vicinity of the extraction port is allowed to return to the inside of the extraction passage to block the dripping and at the same time prevent air from flowing into the inner container. ..

Further, since the volume of air corresponding to the amount of the viscous liquid extracted from the inner container has been reduced from the space between the inner container and the outer container, the outer air corresponding to it has a proper position in the outer container. It is introduced from the check valve provided in the inside to make the air pressure between the inner container and the outer container constant and the outer air pressure, and it is possible to extract the viscous liquid in the inner container by the next operation.

In addition, after the viscous liquid in the inner container is extracted by a certain amount or more, a plurality of leg pieces are provided below the upper part of the inner container to form a hard substantially cylindrical portion. Therefore, with the lower end of the leg as a boundary, the lower tube is inverted and installed inside the upper part, and the viscous liquid located inside the upper part of the inner container can be completely extracted to the outside.

【Example】

 The details of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an explanatory sectional view of an embodiment of the present invention.

In the figure, 1 is a viscous liquid dispensing unit. The viscous liquid dispenser 1 comprises a head 2 and a shoulder 3, and the head 2 can have various shapes. In the illustrated example, an extraction port 4 is provided at the upper end, which is one end. An inlet port 5 is provided at the lower end, which is the other end, and the space between them is an extraction path 6. A check valve 7 capable of permitting the opening toward the extraction port 4 is provided at an appropriate position of the extraction path 6 either integrally with the head 2 as shown in the figure or by incorporating a separate member. Reference numeral 8 is a cap provided outside the head 2 for external fitting when not in use.

Next, the shoulder portion 3 connected to the head portion 2 is provided with an outer attachment portion 9 on the outer side, for example, in an annular shape, and an inner attachment portion 10 on the inner side, for example, in an annular shape. Both of these mounting portions 9 and 10 are preferably provided integrally with the shoulder portion 3 as shown in the drawing, and in some cases it is preferable to provide the outer mounting portion 9 and in some cases the inner mounting portion 10 separately. It is also possible to use a member formed by molding and then integrally forming it. In the example shown in the figure, the outer mounting portion 9 hangs downward on the outer circumference of the shoulder portion 3 and opens downward to provide an annular groove portion 11. The outer mounting piece 12 and the inner mounting piece 13 are sandwiched by the groove portion 11. Is provided. The inner mounting piece 13 is set to be larger than the outer mounting piece 12 in order to increase the area of heat welding or the like during mounting. The inner mounting portion 10 has a structure in which a ring-shaped member is externally fitted to the base end side of a leg piece 14 described later, and the open end of the tubular inner container 15 is sandwiched between the base end portion of the leg piece 14 and the ring-shaped member described above. However, it is also possible to eliminate the ring-shaped member and fix the inner surface of the tubular inner container 15 to the outer surface of the leg piece 14 by means such as welding or adhesion.

Then, a plurality of leg pieces 14 are integrally provided in a ring shape from the inner mounting portion 10 made of the plate material, and these leg pieces 14 form a tubular portion as a whole. In the figure, reference numeral 15 denotes a tubular inner container for containing a viscous liquid, which is fixed to or attached to the plurality of leg pieces 14 or sandwiched between it and a ring-shaped member as described above. As the tubular inner container 15, not only various synthetic resin tubes but also various synthetic resin thin films such as aluminum vapor-deposited on the outer surface, inner surface, or both surfaces are used. In the illustrated example, the upper portion of the tube 15 is fitted or attached to the outer surface of the leg piece 14, and the upper end thereof is fixed to the outer surface of the inner mounting portion 10 by heat sealing or adhesion. The leg pieces 14 and the tubular inner container 15 may be attached to each other by heat welding or the like, but may simply be fitted on the outside. Further, although these leg pieces 14 are integrally formed with the inner mounting portion 10, the upper ends of those formed by integrally molding the leg pieces 14 on the inner surface of the tubular inner container 15 or by attaching a separate member thereto. It is also possible to further employ the one in which the above is fixed to the inner mounting portion 10.

When introducing the viscous liquid into such a tube-shaped inner container 15, the lower end is opened before filling the tube-shaped inner container 15 in the example shown in FIG. By sealing the lower end by heat sealing or the like, it is possible to create a state in which the viscous liquid is contained inside the tubular inner container 15.

The elastic outer container 16 is located outside the viscous liquid dispensing portion 1 and the tubular inner container 15, that is, is located outside the tubular inner container 15 by fitting. It The elastic outer container 16 in the illustrated example includes an elastic cylindrical body 17 and a bottom plate 18 at the lower end. The cylindrical body can retain elasticity if it is made of various synthetic resin thin plates, and the upper end of the cylindrical body is fitted into the groove portion 11 of the outer mounting portion 9 to form the outer mounting piece 12 or the inner mounting piece 13 or the like. Both can be fixed by heat welding or the like. The bottom plate 18 at the bottom is attached by fitting a fitting groove 19 provided on the outer periphery of the bottom plate to the bottom end of the elastic cylindrical body 17 and performing heat sealing or the like.

In the present invention, a check valve 20 capable of unidirectionally taking in air only from the outside to the inside is provided on the bottom plate 18 of the elastic outer container 16 at a proper position, in the illustrated example. ing. This check valve 20 can be realized by a simple structure in which a vent hole 21 is simply provided in the bottom plate 18, the vent hole 21 is closed inside, and a valve body 22 that is elastically opened and closed is attached.

Since the viscous liquid is contained in the viscous liquid-dispensing container, the air between the tubular inner container 15 and the elastic outer container 16 is filled by pressing the cylinder 17 of the elastic outer container 16. It is possible to extract an appropriate amount of viscous liquid from the head extraction port 4 of the viscous liquid dispensing section 1 by pressurizing the container 15 inward, that is, in the direction in which the inner container 15 is squeezed. Then, when the pressurizing operation on the outer container 16 is released, the outer container 16 is restored to its original shape, and the amount of air equal to the amount extracted from the inner container 15 is reduced in the space 23 between the inner and outer containers. Normally, when a certain amount of the viscous liquid content is extracted from the inner container 15 to the outside, naturally, the outside air rapidly flows from the extraction port 4 of the head, but the extraction port is placed at an appropriate position on the extraction path 6. Since the check valve 7 that allows the release in only 4 directions is provided, the outside air does not flow into the inner container and is blocked by the check valve 7, and at the same time, the outer container 16 is put in the proper place, as shown in the example in the figure. In this case, external air is introduced into the space 23 between the inner and outer containers from the check valve 20 provided on the bottom plate 19, and the space 23 and the outside have the same pressure state.

Further, when the viscous liquid in the tubular inner container 15 flows out to the lower end of the leg piece 14 while repeating this operation, the upper portion of the inner container 15 is attached with the leg piece 14 as an interior or the like. Although the whole is tubular, the lower portion of the tubular inner container 15 is internally reciprocally embedded in the tubular body, so that the contents of the tubular inner container 15 are removed from the dispensing unit 1 by the pressurization of the elastic outer container 16. Almost all of them can be extracted.

[0018]

[Effect of the device]

 As described above, in the viscous liquid dispensing container according to the present invention, the viscous liquid contained in the inner container can be appropriately dispensed, and air corresponding to the liquid dispensing amount is sucked from the extraction port after dispensing. Never. In addition, since multiple leg pieces are attached to the upper part of the inner container, the lower part of the tubular inner container is separated from the lower end of the leg part after the viscous liquid in the lower part of the inner container is extracted. It is turned inside and the viscous liquid above the inner container can be extracted.

Further, also in the manufacturing thereof, it is not necessary to partially weld the thin film to the inner surface of the outer container, and it is sufficient to simply attach the inner container in association with the inner surface or the outer surface of the plurality of leg pieces. It is easy and cheap in cost, and it is easy to fill the inner container with viscous liquid if the lower end of the inner container is opened, and the sealing of the lower end is also easy.
