Description

Refill container

The present invention relates to a container for refilling a cosmetic such as a liquid detergent or a softener, an edible oil, a food such as instant coffee, or the like.

A cosmetic such as a liquid detergent or a soft processing agent, or a food such as an edible oil or instant coffee is stored in a dedicated container having a shape that is easy to use. The construction of the special container is also quite strong, whereby, because of its high price, the product of the refill container with only the refilled contents is often sold, so that the content can be repeatedly used during the use of the contents. Use this special container.

For example, since the container of the liquid detergent needs to be metered and used to take out a suitable amount each time the detergent is used, a rigid plastic container having a nozzle at the injection port is used as a reusable container. Easy to infuse in lightweight cups. In this container, as a container for refilling a content for replenishing contents, a container having a spout or a container having a spud formed on a flexible container made of a flexible wrap film is generally used.

Reusable rigid containers are specially designed for easy filling, so for reusable containers, it is not necessarily the convenience of refilling operations that replenish the contents from the refill container. Designed container.

On the other hand, the refilling container is not limited to the convenience of the heavy-duty manufacturing, and it is not necessarily the convenience of the heavy-filling operation in which the self-reloading container is added.

For example, in the case where only the container of the injection port is formed on the flexible container made of the flexible packaging film, it may be difficult to maintain the shape of the mouth and the injection port may be bent to deteriorate the discharge property. Even if the embossing process is used to reinforce the container for the outlet, it is not enough to rely solely on the embossing, and the injection port may be bent. Therefore, it takes time to refill, and during this period, the feeling of uneasiness of overflowing the contents from the nozzle of the container body often occurs, and the work has to be performed with caution.

Further, in the case of the refilling container in which the plug of the molding tube is provided at the injection port, the problem of the injection port bending does not occur, but in the container manufacturing stage, the tube is likely to be generated when the molding tube is installed. The problem of shedding or film rupture. Further, since the unfilled empty containers are not uniformly stacked when they are filled in the filling machine, the empty containers are not easily aligned, and the applicability of the filling machine is poor. Further, in the use stage, when the filling port is opened, there is also an inconvenience that a knife or scissors is required in order to cut the tube portion.

Here, a refill container is proposed which can perform unpacking of a refill container by using a nozzle provided on a re-used container, and in the refilling operation, the refill container can stand on its own, even if not Hand support is fine. The heavy-filling container which is not supported by the hand is provided with a coupling member which is detachably attached to the opening of the reusable container and which is detachably attached, and a container sealing member for sealing the container body for refilling the container. Container (refer to Patent Document 1).

From the viewpoint of cost, it is advantageous to use the packaging bag 60 which is, for example, a container for refilling which is formed by sealing the periphery of two packaging films 61 in the front and back shown in FIG. The package 60 can be provided with a dispensing opening 62 of any width that conforms to the diameter of the container. However, when the edge of the film 61 of the two sheets is sealed to form a spout, when the contents are poured, the opening is pulled by the sealed ends, and the film in the watch becomes a suspected close contact state. . Therefore, there is a problem that the injection port is blocked. In addition, there is a problem that the injection port is easily bent, and in the reloading operation, the discharge port is peeled off from the reused container.

In order to solve the problem of clogging or bending of the outlet, it is proposed that a plurality of other component portions having different compositions from the film are inserted into the injection port portion (see Patent Document 2), or that the film near the injection port is expanded to have a three-dimensional shape. A method of securing an opening area (refer to Patent Document 3).

However, in addition to the problems of the steps of installing other members, the steps of applying a deep embossing process to the film, etc., the packaging bags cannot be stacked neatly in the supply portion of the packaging bag during filling. The problem of the bag, or the opening formed by sealing the two films in the watch, because there are seal portions at both ends, the width of the opening is reduced to be equivalent to the width of the portion, and there is a basic condition that the sufficient opening area cannot be ensured. problem. If it is not possible to ensure a sufficient opening area, the time required for the refilling will be longer.

In order to solve this problem, it has been proposed to bend a film constituting a packaging bag to form a single side of the injection port, and to form a single-side packaging bag for the sealing portion of the injection port (see Patent Documents 4 and 5).

Hereinafter, the refill container 1 according to the first embodiment of the present invention will be described in detail with reference to the first, second, and second embodiments.

Fig. 1 is a schematic plan view showing a refill container 1 according to a first embodiment of the present invention. Fig. 2A is a schematic cross-sectional view showing a cross section taken along line II-II in Fig. 1 of the refill container 1. Fig. 2B is a schematic cross-sectional view showing the configuration of the layered body of the refill container 1 in the section II-II in Fig. 1 of the refill container 1.

As shown in FIGS. 1 and 2A, the heavy-fill container 1 of the present embodiment includes a main body surface layer 2, a main body back surface layer 3, a bent portion 6, and a sealing portion 20. Further, as shown in FIG. 2B, the refill container 1 is formed of a laminate 10 having at least a substrate 11 and a sealing layer 12.

The refill container 1 has the laminated layers 10 facing each other with the sealing layer 12 facing inward, and is loosely bent at the top. The refill container 1 seals the periphery of the folded laminated body 10.

Thus, the refill container 1 is formed by bending a laminated body 10 to form a bent portion 6 bent at the top, a bulk surface layer 2 as a main surface at the boundary of the bent portion 6, and The main body back surface layer body 3 is the other main surface with the bent portion 6 as the boundary. The body surface layer 2 forms a film of the surface of the body. In addition, the body back surface layer 3 forms a film on the back side of the body. Further, the refill container 1 is formed by sealing the periphery of the folded laminated body 10 to form the sealing portion 20.

Moreover, in the refill container 1 shown in Fig. 1, the opening for filling the contents therein is omitted. The opening may be provided, for example, on one of the sealing portions 20, and the portion of the sealing portion 20 may be sealed after the contents are filled.

The body surface area layer 2 and the body back area layer body 3 form the front and back surfaces of the refill container 1, respectively. Further, the main body surface layer 2 and the main body back surface layer 3 are formed in a bag shape by sealing the side edge and the lower edge thereof by the sealing portion 20. Further, the body surface layer body 2 is a portion of the layer body 10 and is a film of the surface of the body. Further, the main body back surface layer body 3 is a part of the laminated body 10 and is a film on the back surface of the main body.

The sealing portion 20 includes a side seal portion 22 and a bottom seal portion 23 . The side seal portion 22 is for sealing the side edges of the body surface layer body 2 and the body back surface layer body 3. The bottom sealing portion 23 is for sealing the lower surface of the body surface layer 2 and the body back surface layer 3. The sealing portion 20 is provided with an injection port sealing portion 24 for sealing a part of the upper side of the side of the main body surface layer 2 and the main body back surface layer 3 from the lower side of the bent portion 6.

The bent portion 6 is formed by the bent end side of the laminated body 10 and the injection port sealing portion 24 provided at the lower end side. The bent portion 6 forms the injection port 31 and the outflow path 33 of the contents by the end portion of the laminated body 10 and the injection port sealing portion 24.

The injection port 31 is opened by cutting a part of the side seal portion 22. The outflow path 33 is formed in a horizontally long shape from the injection port 31.

The laminate 10 is, for example, a laminate film used in a usual flexible package. The substrate 11 is a film layer of a substrate. As the substrate 11, a paper made of one to several layers, a metal foil or a synthetic resin film is used. For example, the substrate 11 is made of low density polyethylene resin (LDPE), high density polyethylene resin (HDPE), linear low density polyethylene resin (LLDPE), polypropylene resin (PP), polyolefin elastic. a polyester resin such as a polyolefin resin such as a polyethylene terephthalate, polyethylene terephthalate (PET), polybutylene terephthalate (PBT) or polyethylene naphthalate (PEN). Cellulose resin such as cellophane or cellulose triacetate (TAC), polymethyl methacrylate (PMMA) resin, ethylene-vinyl acetate copolymer resin (EVA), ionic polymer, polybutene resin, Polyacrylonitrile resin, polyamine resin, polystyrene resin (PS), polyvinyl chloride resin (PVC), polyvinylidene chloride resin (PVDC), polycarbonate resin (PC), fluorine A synthetic resin film such as a resin or a urethane resin, or a monomer or composite such as paper or metal foil. The substrate 11 may contain a printing layer and an adhesive layer as needed.

In terms of paper, high-grade paper, single-sided art paper, coated paper, high-gloss printing paper, mold paper, and the like can be used. Usually, in order to stably open the injection port, embossing is applied to the injection nozzle. However, when paper is used as the laminate, embossing causes defects such as cracks on the paper. However, in the present embodiment, by bending one of the laminated bodies 10, it is possible to stably open the injection port without embossing, and it is effective to use paper from the viewpoint of the environment.

The sealing layer 12 is generally made of a polyolefin resin. Specifically, as the sealing layer 12, a vinyl resin such as a low-density polyethylene resin, a medium-density polyethylene resin, a linear low-density polyethylene resin, an ethylene-vinyl acetate copolymer, an ethylene-α-olefin copolymer, or the like can be used. A polypropylene resin such as a polymer resin, an ethylene propylene random copolymer, an ethylene propylene block copolymer, or a propylene-α olefin copolymer. Further, the sealing layer 12 may also be a multilayer film obtained by compounding these resins.

In the specific configuration example of the laminated body 10, a film composed of a PET/printing layer/adhesive layer/extending polyamide film (hereinafter abbreviated as ONY)/adhesive layer/LLDPE, or ONY/adhesive may be mentioned. Layer / LLDPE, ONY / Adhesive Layer / ONY / Adhesive Layer / LLDPE, Paper / LDPE / Aluminum Foil / LDPE /, Paper / LDPE.

The refill container 1 constructed as described above is formed by loosely bending a laminated body 10 to form the bent portion 6, so that the bent portion 6 can generate an elastic effect for returning the laminated film. That is, a restoring force is generated in the bent portion 6. Therefore, the cross section of the outflow path 33 is always in a state of being inflated toward the upper portion. Therefore, the sectional area of the injection port 31 can be broadly ensured, and a large amount of contents can be discharged at one time. Further, by simultaneously making the cross section of the outflow path 33 into a state of expansion, the outflow path 33 is not easily bent at the time of the heavy loading operation.

Next, the refill container 100 according to the second embodiment of the present invention will be described in detail with reference to FIGS. 3, 4A and 4B. The same components as those of the above-described refill container 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 3 is a schematic view showing a refill container 100 according to a second embodiment of the present invention. Fig. 4A is a cross-sectional schematic view showing a section IV-IV of the same refill container 100. In addition, FIG. 4B is a cross-sectional schematic view showing the IV-IV cross section in a state in which the container body belonging to the same refill container 100 is opened.

The refill container 100 includes a main body surface layer 2, a main body back surface layer 3, and a bottom tape 104. The refill container 100 is formed by sealing the respective sealing layers 12 to each other and sealing the periphery. The bottom tape 104 is formed of the same material as the laminated body 10. The bottom belt 104 is bent at the lower portion of the container with the sealing layer 12 facing outward. One end of the bottom belt 104 forms a bottom sealing portion 123 together with the body surface layer 2, and the other end forms a bottom sealing portion together with the body back surface layer 3. 123, thereby forming the bottom surface of the container. A bag of this shape is also referred to as a stand pouch. This stand has the feature that a large-capacity container can be realized because the bottom surface is wide.

The bent portion 6 is formed in the same manner as the bent portion 6 of the heavy-fill container 1, and a laminated body 10 is loosely bent at the top with the sealing layer facing inward. Further, the bent portion 6 forms an outflow path 33 that reaches the contents of the injection port 31 in a horizontally long manner together with the injection port sealing portion 124 provided at the lower portion of the bent portion 6.

Further, the refill container 100 is formed by cutting a part of the bent portion 6 and providing a filling opening portion 141 for filling the contents. Moreover, the filling opening 141 is sealed after filling the contents. In the third drawing, the state in which the filling opening portion 141 is sealed to form the top sealing portion 121 is shown.

In the heavy-fill container 100 having such a configuration, in particular, when the contents are liquid, the contents can be smoothly flowed to the linear outflow path 33 by the bent portion 6 when the contents are discharged. Therefore, the refill container 100 can be quickly dispensed. In particular, the refill container 100, which is called the shape of a stand-up pouch, is more effective because the capacity of the container is large, so that the bent portion 6 that can be quickly dispensed can be used.

Further, since the opening portion 141 for filling is provided at the top of the container, there is an advantage that the filling operation of the contents can be easily performed.

Next, a refill container 200 according to a third embodiment of the present invention will be described in detail with reference to Fig. 5. The same components as those of the above-described refill container 1 and the refill container 100 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 5 is a schematic view showing the configuration of a refill container 200 according to a third embodiment of the present invention. Fig. 6 is a schematic view showing a series of refilling operations using one of the same refill containers 300. Fig. 7 is a schematic view showing a series of refilling operations using one of the same refill containers 300. Fig. 8 is a schematic view showing a series of refilling operations using one of the same refill containers 300.

The refill container 200 is formed by the injection port sealing portion 224 forming the cutting portion 225, and the outflow path 33 is formed as a protruding injection nozzle 232.

The refill container 200 is provided with a handle 226 that can be accommodated in the shape of the cutting processing portion 225 on the side opposite to the side on which the injection nozzle 232 is formed. In order to manufacture the refill container 200 shown in Fig. 5, the laminated body 10 having a width twice the width of the height of the refill container 200 is cut so that the surface of the sealing layer 12 faces the inside. Bend loosely and make it opposite.

Then, the body surface layer body 2 and the body back surface layer body 3 are formed by the bending portion 6 as a boundary, and the body surface area layer body 2 and the body back surface layer body 3 are continuously provided. Here, the continuous supply means that a plurality of laminated bodies 10 having a size of a plurality of heavy-fill containers 200 are bent in such a manner as to form a plurality of heavy-fill containers 200, and the body surface layer 2 and the back surface layer of the body are provided. The case of body 3.

Then, between the body surface layer 2 and the body back surface layer 3, a bottom tape 104 which is folded into two in such a manner that the surface of the sealing layer 12 faces outward is continuously provided. Next, after the laminated body 10 and the bottom tape 104 are sealed as necessary, the outline of the heavy-fill container 200 is cut, and the processed portion 225 and the handle 226 are cut to form a container.

In addition, the refill container 200 includes a filling opening 141 for cutting a part of the bent portion 6 and filling the contents.

According to the refill container 200 having such a configuration, the cut-out processing portion 225 is provided so that the outflow path 33 is formed in the protruding discharge nozzle 232. This injection nozzle 232, for example, can be inserted into the plug portion of the reusable container.

By forming the protruding injection nozzle 232 and inserting the injection nozzle 232 into the socket portion of the container, it is advantageous to improve the workability when the filling material in the refill container 200 is reloaded into the container. Further, the shape of the processed portion 225 can be selected to have an appropriate shape depending on the structure around the plug portion of the container to be reused.

Further, the cutting unit 25 is originally a discarding portion, and as shown in Fig. 5, the handle 226 is designed to be accommodated in the shape of the cutting processing portion 225 of the adjacent heavy loading container 200 at the time of manufacture, and is not used. The handle 226 can be attached by adding material in particular. By the presence of the handle 226, the handle 226 can be gripped for refilling operation, so that the refilling operation can be performed more safely and simply.

Further, since the refill container 200 is provided with the cut processing portion 225 and the handle 226 in the side seal portion 22, it is difficult to provide the filling opening portion 141 having a sufficient width at a position other than the bent portion 6. Therefore, it is preferable to provide the position of the opening portion 141 for filling in the bent portion 6.

Next, referring to Figures 6, 7, and 8, a series of refilling operations using the refill container 200 will be described.

As shown in Fig. 6, after the heavy-fill container 200 of the present embodiment is held, the front end of the discharge nozzle 32 is cut off to open the injection port 31. The nozzle 52 of the reusable container 51 that has been used up is inserted into the injection port 31. In the figure, the container 51 that is repeatedly used is a plastic container having a nozzle cap 53 having a nozzle 52.

Next, as shown in FIG. 7, the discharge nozzle 232 of the refill container 200 is surely inserted into the nozzle cap 53 of the container 51 to be reused. Next, as shown in Fig. 8, the positional relationship between the container 51 and the refill container 200 that are repeatedly used is kept constant, and the entire nozzle 232 is vertically lifted, and the container 200 is refilled at once. The contents are injected into the container 51 which is reused.

As described above, in the refill container of the present invention, by providing the bent portion 6, it is possible to secure a large-area injection port without using a special plastic spigot or the like. In addition, the size of the outlet can be designed freely in accordance with the shape of the plug of the target reusable container. Therefore, it is extremely valuable as a special refill container that can perform rapid reloading operations.

Next, a refill container 300 according to a fourth embodiment of the present invention will be described in detail with reference to FIG. The same components as those of the above-described respective refill containers 1, 100, and 200 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 9 is a schematic view showing a portion of the injection port 31 of the refill container 300 according to the fourth embodiment of the present invention.

The refill container 300 is formed on the outer surface of the main body surface layer 2 and the main body back surface layer 3 which are to be the portions of the injection port 31, and a half tangent 334 is provided in the discharge nozzle 332. With such a configuration, the injection port 31 can be easily formed by tearing a portion of the half tangent 334 by hand. The portion to be the discharge port 31 is a portion to be opened, and as shown in Fig. 6, if the nozzle 332 is present, it is preferable to provide a position at which the tip end of the nozzle 332 is retracted. This is to make it easy to tear the front end of the dispensing nozzle 332 with the hand. The half tangent 334 is generally formed by a method of cutting by a knife and a method of laser processing. However, since the laser processing method can form a uniform and stable slit, it is preferable to form the half tangent 334 by laser processing.

Hereinafter, a specific example of the refill container 300 of the present embodiment will be described as a first embodiment.

(Example 1)

As the main body surface layer 2 and the main body back surface layer 3, the laminated body 10 formed as follows is used.

<Configuration of the laminated body 10 for the body surface layer 2 and the body back surface layer 3>

As the base tape 4, the laminated body 10 formed by the following structure is used.

<Configuration of the laminated body 10 for the base tape 4>

ONY (UNITIKA company ONM; 25μm) / LLDPE (same as above; 120μm)

Using the laminated body 10 described above, a stand-up pouch having the shape shown in Fig. 5 was produced as the refill container 300. Further, as the filling opening portion 141, a part of the bent portion 6 is cut out and used as the filling opening portion 141. Further, a half-cut line 334 is provided as a predetermined opening portion by laser processing at a portion of the injection port 31 which is to be the end portion of the injection nozzle 332 before the injection nozzle 332. The household liquid detergent is filled in the refill container 300 obtained in the above, and the filling opening 141 is heat-sealed to form a refilling detergent.

After opening the predetermined opening of the tip end of the dispensing nozzle 332 of the refilling container for refilling the detergent by hand, the opening of the injection port 31 is opened, and the contents are carried out according to the steps shown in Figs. 7 to 9 The operation of refilling the detergent in a dedicated reusable container 51. As a result, no detergent is spilled or spilled, and the refilling operation can be completed extremely quickly.

Next, the refill container 400 according to the fifth embodiment of the present invention will be described in detail with reference to the drawings of the tenth, eleventh, twelfth, and eleventh aspects, and the third embodiment. The same components as those of the above-described respective refill containers 1, 100, 200, and 300 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 10 is a schematic view showing the configuration of a refill container 400 according to a fifth embodiment of the present invention. In addition, FIG. 11 is a cross-sectional view schematically showing a configuration of a cross section taken along the line XI-XI of the same refill container 400. Fig. 12A is an enlarged view showing the configuration of the ejection nozzle 432 of the same refill container 400. Fig. 12B is a cross-sectional view schematically showing the configuration of the injection port 31 of the same injection nozzle 432. Fig. 13A is an enlarged view showing the configuration of the injection nozzle 482 of the refill container of the prior art. Fig. 13B is a cross-sectional view schematically showing the configuration of the injection port 483 of the same injection nozzle 482.

As shown in Figs. 10 and 11, the refill container 400 of the present embodiment is composed of a laminate 10 having at least a substrate 11 and a sealing layer 12. Further, as shown in FIGS. 10 and 11, the refill container 400 includes the main body surface layer 2 and the main body back surface layer 3, and the respective sealing layers 12 are opposed to each other to seal the periphery. That is, the refill container 400 bends one of the laminated bodies 10 so that the sealing layer 12 faces inward, and forms the bent portion 6, the main body surface layer 2, and the main body back surface layer 3. The bent portion 6 forms a discharge nozzle 432 for injecting a content together with the injection port sealing portion 424. The front end of the injection nozzle 432 can be formed by cutting along the predetermined opening line 434 to form the injection port 31.

Further, as shown in FIG. 12A, the refill container 400 is formed such that the length of the predetermined opening line of the nozzle 432 is A (mm), and the width of the opening of the injection port 31 is B (mm). The following relationship is satisfied: A-4 (mm) ≦ B (mm) ≦ A-0.5 (mm) shape. This relational expression shows that the width of the injection port sealing portion 424 is 0.5 mm or more and 4 mm or less. With such a configuration, the opening width B of the injection port can be made wider with respect to the length A of the predetermined opening line, that is, the width of the injection nozzle 432. Thereby, it can be easily inserted into the nozzle cap portion of the body of the reused container 51, and the flow rate of the contents at the time of the heavy loading operation can be largely ensured. Therefore, the refill container 400 can be subjected to a smooth and rapid refilling operation. Further, the A size and the B size in Fig. 12A are values measured in a state where the injection nozzle 432 is pressed flat. As shown in Fig. 12B, the cross section of the nozzle is actually in a state in which the side body is inflated by the elasticity of the laminated body 10.

In the case of A-4 (mm) > B (mm), the width of the injection port sealing portion 424 of the injection nozzle 432 is too wide, and it becomes difficult to insert into the nozzle cap portion of the main body of the container 51 to be reused. In the case where B (mm) > A - 0.5 (mm), the width of the injection port sealing portion 424 is too narrow, and there is a fear that the pressure resistance when the pressure is applied to the refill container 400 from the outside is insufficient.

Fig. 13A is an enlarged view showing a dispensing nozzle 482 of a conventional refill container. In addition, FIG. 13B is a cross-sectional view schematically showing the injection port 483 of the dispensing nozzle 482. As described above, the nozzle 482 of the prior art has the sealing portion 484 on the upper and lower sides of the injection port 483. Therefore, the length A of the predetermined opening line 485 is increased with respect to the opening width B. Further, since the injection port 483 cannot be opened wide, there is a problem that the injection performance is poor, in addition to the problem that the nozzle cap is not easily inserted.

On the other hand, in the refill container 400 shown in FIG. 10, the main body surface layer body 2 and the main body back surface layer body 3 are sealed in the side seal portion 22 and the bottom seal portion 23, and are formed in a bag shape. Further, in the actual container, the filling opening for filling the contents is required, but in FIG. 10, the filling opening portion is omitted. In the refill container 400 shown in Fig. 10, a filling opening portion can be provided in the side seal portion 22 or the bottom seal portion 23.

The predetermined opening line 434 of the front end portion of the nozzle 32 is indicated as an imaginary line of the unsealing position, and in order to make the opening position clear, a print display or the like can be actually used. In addition, the predetermined opening line 434 may also utilize a half tangent line 334 provided on the outer surface of the body surface layer body 2 and the body back surface layer body 3. Thus, by using the half-cut line 334 for the predetermined opening line 434, the portion of the predetermined opening line 34 is torn by hand, and the injection port 31 can be easily formed.

It should be a part of the injection port 31, and it is preferable to provide a position which is provided at the front end of the general injection outlet 432. This is to make it easy to hold the front end of the injection nozzle by hand. Further, a V-shaped or U-shaped notch or a score line may be provided at the injection port sealing portion 24 corresponding to the predetermined opening line 434, or the front end portion of the injection port sealing portion may be processed to be wider. Thus, the ease of opening of the tip end of the injection nozzle 432 can be further improved by the notch, the inscribed line, and the processing of the front end portion of the sealing portion to be wider.

Next, a refill container 500 according to a sixth embodiment of the present invention will be described in detail with reference to Figs. 14, 15A and 15B. In addition, the same components as those of the above-described respective refill containers 1, 100, 200, 300, and 400 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 14 is a schematic view showing the configuration of a refill container 500 according to a sixth embodiment of the present invention. Fig. 15A is a cross-sectional view schematically showing the configuration of the XV-XV cross section of the same refill container 500. Fig. 15B is a cross-sectional view schematically showing a state in which the unsealed container 500 is opened.

In the present embodiment, the refill container 500 has the main body surface layer 2 and the main body back surface layer 3, and the respective sealing layers are opposed to each other to form a surrounding seal. The bottom belt 4 is bent at the lower portion of the container with the sealing layer facing outward, one end of the bottom belt 4 forms a bottom sealing portion 123 together with the body surface layer 2, and the other end forms a bottom sealing portion together with the body back surface layer 3. 123, thereby forming the bottom surface of the container. This type of packaging bag is called a standing bag, and has a feature that a container having a large capacity can be realized because the bottom surface is wide.

The bent portion 6 is formed by bending one piece of the laminated body at the top with the sealing layer facing inward. The bent portion 6 forms an outflow path 33 that reaches the contents of the injection port 31 together with the injection port sealing portion 24 and the cutting processing portion 525. That is, the refill container 500 is formed in a shape in which the cutting processing portion 525 is provided on the refill container 100. In addition, the refill container 500 has a dispensing nozzle 432.

With such a configuration, particularly when the contents are liquid, the refill container 500 can smoothly flow the contents onto the linear outflow path 33 when the contents are discharged, so that the contents can be quickly ejected. . Further, the refill container 500 is formed into a shape of a so-called vertical pouch, and since the capacity of the container is large, a larger effect can be obtained.

Next, a refill container 600 according to a seventh embodiment of the present invention will be described in detail with reference to Fig. 16. The same components as those of the above-described respective refill containers 1, 100, 200, 300, 400, and 500 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 16 is a schematic view showing the configuration of a refill container 600 according to a seventh embodiment of the present invention.

As shown in Fig. 16, the refill container 600 of the present embodiment is provided on the opposite side of the cutting processing portion 225 of the injection port sealing portion 224 forming the injection nozzle 32, similarly to the refill container 300. A handle 226 that can be received in the shape of the cut processing portion 225. Further, the refill container 600 is not a discharge nozzle 232 having a refill container 300 but a discharge nozzle 432 having a refill container 400. In this manner, the refill container 600 forms the cut-out processing portion 225 by the injection port sealing portion 224, and forms the outflow path 33 as the protruding injection nozzle 432. Further, the shape of the processed portion 225 can be selected to have an appropriate shape depending on the structure around the plug portion of the container to be reused.

When the refill container 600 shown in Fig. 16 is to be manufactured, similarly to the refill containers 200 and 300, the laminated body 10 having a width twice the width of the container is cut to the surface of the sealing layer 12. The inner side is bent toward the inner side to be opposed to the inner surface layer body 2 and the main body back surface layer body 3. This laminated body 10 is continuously provided. A bottom tape 4 which is folded into two in a manner such that the surface of the sealing layer faces outward is continuously provided between the body surface layer 2 and the body back surface layer 3. After the necessary sealing, the container is formed by cutting.

In addition, the refill container 600 is provided with a portion for opening the bent portion 6 to form a filling opening 141 for filling the contents. In this example, since the side seal portion 22 has the cut processing portion 25 and the handle 26, it is difficult to provide the filling opening portion having a sufficient width in addition to the bent portion 6. Therefore, the position of the opening portion 41 for filling is preferably provided in the bent portion 6.

Next, using the sixth, seventh, and eighth drawings, a series of refilling operations of the refilling container 600 will be described in the same manner as the refilling containers 200 and 300. As shown in Fig. 6, after the refill container 600 is held, the front end of the injection nozzle 432 is cut off to open the injection port 31. The nozzle 52 of the container 51 which has been used up and reused is inserted into the injection port 31.

Next, as shown in Fig. 7, a state in which the discharge nozzle 32 of the refill container 600 is surely inserted into the nozzle cap 53 of the repeatedly used container 51 is formed. Then, as shown in Fig. 8, the positional relationship between the container 51 and the refill container 600 which are repeatedly used is kept constant, and the entire nozzle is closed so that the nozzle 32 is vertical, and the container 600 is refilled at a time. The contents are poured into the container 51 which is reused.

In this way, the refill container 600 of the present invention can ensure a large-area injection outlet without using a special plastic bolting port or the like, and the size of the injection outlet can match the shape of the plug of the target reusable container. Freely designed, it is extremely valuable as a special refill container for quick reloading operations.

Next, the second embodiment to the seventh embodiment will be described as a specific example of the refill container 600 of the present embodiment, and Comparative Example 1 to Comparative Example 6 which are compared with the refill container 600 will be described.

And fill the same content.

The predetermined opening line of the tip end of the dispensing nozzle of each of the heavy-filling detergent containers (refilling container 600) is torn by hand to open the injection port. Then, according to the steps shown in Figs. 6 to 8, the operation of refilling the detergent of the contents into the dedicated reusable container 51 (bottle) is carried out. At this time, the ease of insertion into the bottle (insertion) and the speed of injection (injectability) were evaluated. In addition, the pressure resistance of the unfilled heavy-fill container was evaluated. Table 1 shows the results of these experiments. Further, each of the embodiments from the second embodiment to the seventh embodiment (← is a cross-sectional line or a mesh line in the table or the figure, and is not described as a matter of this, and therefore is changed), and the A and B sizes are displayed. The range of the relationship of A-4 (mm) ≦ B (mm) ≦ A - 0.5 (mm) is satisfied. Further, the nozzle caps of the reusable containers 51 used in the heavy loading operations of Examples 1 to 3 and Comparative Examples 1, 2, and 5 had an inner diameter of 15 mm. Further, the nozzle caps of the reusable containers 51 used in the heavy loading operations of Examples 4 to 6 and Comparative Examples 3, 4, and 6 had an inner diameter of 27 mm.

As shown by the results in the table, the refill container 600 of the present embodiment having the injection nozzle that satisfies the relationship of A-4 (mm) ≦ B (mm) ≦ A - 0.5 (mm) shows the insertion into the bottle. Balanced results in terms of sex, injectability and pressure resistance. Further, regarding the relationship of A-4 (mm) ≦ B (mm) ≦ A - 0.5 (mm), not only the refill container 600 satisfies this relationship, but also the refill container 400, 500 satisfies this relationship. The heavy loading container 400, 500 of the outlet 431 can also obtain the same effect as the refill container 600.

Next, the refill container 700 according to the eighth embodiment of the present invention will be described in detail with reference to the drawings of Figs. 17, 18A, 18B, and 18C. The same components as those of the above-described respective refill containers 1, 100, 200, 300, 400, 500, and 600 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Figure 17 is a schematic view showing the configuration of a refill container according to a seventh embodiment of the present invention. Fig. 18A is an enlarged view showing the configuration of the injection port portion of the same refill container. Fig. 18B is a cross-sectional view schematically showing the configuration of the XVII-XVII cross section of the same discharge port. Fig. 18C is a cross-sectional view schematically showing a state in which the area of the same injection port is maximized in the XVII-XVII cross section.

As shown in Fig. 17, the refill container 700 of the present embodiment is composed of a laminated body 10, and has a main body surface layer 2 and a main body back surface layer 3, and the respective sealing layers face each other and surround each other. The seal is formed. Further, the refill container 700 is formed by bending one piece of the laminated body 10 so that the sealing layer 12 faces inward, and forms the bent portion 6, the main body surface layer body 2, and the main body back surface layer body 3. The bent portion 6 forms an outflow path 33 for injecting the contents together with the injection port sealing portion 24. The refill container 700 can form the spout 731 by cutting the front end of the outflow path 33 along a predetermined unsealing line 734.

In the refill container 700 shown in Fig. 17, the main body surface layer 2 and the main body back surface layer 3 are sealed in a side seal portion 22 and a bottom seal portion 23 to form a bag shape. In the actual container, the filling opening for filling the contents is required. However, in Fig. 17, the filling opening portion is omitted. In the refill container 700 shown in Fig. 17, an opening for filling can be provided in the bottom seal portion 23 or the side seal portion 22.

The predetermined opening line 734 of the front end portion of the outflow path 33 is an imaginary line indicating the opening position, and in order to make the opening position clear, printing display or the like can be actually performed. In addition, it may be a half tangent provided on the outer surface of the body surface layer body 2 and/or the body back surface layer body 3. By forming such a configuration, the portion of the predetermined opening line 734 is torn by a hand, and the injection port 31 can be easily formed. The half-cut line is generally formed by a method of cutting by a knife and a method of laser processing, but it is more suitable because a laser processing method can form a uniform and stable slit. Further, by providing a V-shaped or U-shaped notch or engraving line at the injection opening sealing portion corresponding to the predetermined opening line 734, or by forming the front end portion of the injection port sealing portion 24 into a wider processing, the opening can be further improved. degree.

Further, as shown in Fig. 18A, when the width of the set outlet 731 is C (mm) and the sectional area of the opening of the discharge port 731 is D (mm ² ), the outlet 731 of the refill container 700 is attached. A method of satisfying the following relationship is formed: 1/10 × (C ² /π) (mm ² ) ≦ D (mm ² ) ≦ C ² / π (mm ² ). This relational expression indicates that the opening cross-sectional area D (mm ² ) of the opening 731 is 1/10 of the ratio (C ² /π) (mm ² ), that is, the theoretical maximum value of the sectional area of the opening is large.

According to the refill container 700 of such a configuration, the opening sectional area B of the opening of the injection port 731 can be made wider. In addition, the nozzle cap portion of the body of the reusable container 51 can be easily inserted. Therefore, the flow rate of the contents at the time of the refilling operation can be largely ensured. Therefore, the refill container 700 can be subjected to a smooth and rapid refilling operation.

Further, the C dimension in Fig. 18A is a value measured in a state where the injection port 731 is pressed flat. As shown in Fig. 18B, the cross section of the actual injection port 731 is in a state in which the side body is inflated by the elasticity of the laminated body 10. At this time a cross-sectional area of the opening portion of the spout 731 is D (mm ^2). In addition, the C ² / π is assumed to be the opening cross-sectional area D of the injection port 731 when the injection port 731 is a true circle, and this value is the maximum value of the opening cross-sectional area D of the injection port 731.

In the case of 1/10×(C ² /π)(mm ² )>D(mm ² ), the opening portion D of the opening of the injection port 731 is small, and there is a nozzle that becomes difficult to insert the body of the container 51 that is repeatedly used. The situation inside the cap. In addition, it is impossible to ensure the flow rate at the time of dispensing, and there is a fear that the rapid reloading operation cannot be performed.

Next, the refill container 800 according to the ninth embodiment of the present invention will be described in detail with reference to Figs. 14, 15A, 15B, 18A, 18B, and 18C. The same components as those of the above-described respective refill containers 1, 100, 200, 300, 400, 500, 600, and 700 are denoted by the same reference numerals, and detailed description thereof will be omitted.

The refill container 800 of the present embodiment has the main body surface layer 2, the main body back surface layer 3, and the bottom strip 4, and has the respective sealing layers facing each other to seal the periphery, similarly to the refill container 500. form. The bottom belt 4 is bent at the lower portion of the container with the sealing layer facing outward. One end of the bottom belt 4 forms a bottom seal portion 123 together with the body surface layer 2, and the other end forms a bottom seal portion 123 together with the body back surface layer body 3, thereby constituting the bottom surface of the container. A bag of this type is called a stand bag, and has a feature that a container having a large capacity can be realized because the bottom surface is wide.

The bent portion 6 is formed by bending the one laminated body 10 at the top with the sealing layer facing inward, and the bent portion 6 forms the contents reaching the injection port 731 together with the injection port sealing portion 24 and the cutting processing portion 25. The outflow path 33 exits the nozzle 832 as a protrusion. In other words, the refill container 800 has a configuration in which the ejection nozzle 832 having the injection port 731 formed different from the ejection nozzle 432 of the refill container 500 is provided. Therefore, the injection nozzle 832 can obtain the same effect as the refill container 700 by the injection port 731.

Further, in the refill container 800, one portion of the bent portion 6 is cut away to form a filling opening portion 41 for filling the contents. In the fourteenth aspect, the state in which the top sealing portion 21 is formed by sealing the opening portion 41 for filling is shown. As described above, when the opening portion for filling is provided at the top of the container, there is an advantage that the filling operation of the contents can be easily performed.

The cut-out processing portion 25 is formed by the injection port sealing portion 24, and the outflow path 33 is formed as a protruding injection nozzle 832. Further, the shape of the processed portion 25 can be selected to have an appropriate shape depending on the structure around the plug portion of the container to be reused.

In order to manufacture the refill container shown in Fig. 16, the laminated body 10 which is cut into a width twice the width of the container is bent at the top so that the surface of the sealing layer 12 faces inward. The body surface layer body 2 and the body back surface layer body 3 are oriented. This laminated body 10 is continuously provided, and between these, the bottom tape 4 which is folded in two in such a manner that the face of the sealing layer 12 faces outward is continuously provided. Then, after the main surface area layer 2, the main body back surface layer 3, the side seal portion 22 of the bottom belt 4, the bottom seal portion 123, the injection port seal portion 24, and the like are sealed, they are cut into containers. .

6 to 8 are schematic views showing an example of a series of refilling operations using the refill container 900 of the present embodiment. As shown in Fig. 7, after the heavy-fill container 900 of the present embodiment is held, the front end of the injection nozzle 832 is cut off to open the injection port 731. The nozzle 52 of the container 51 that has been used up and reused is inserted into the spout 731. In the figure, the container 51 that is repeatedly used is a plastic container having a nozzle cap 53 having a nozzle 52.

Next, as shown in Fig. 7, a state in which the discharge nozzle 832 of the refill container 900 is surely inserted into the nozzle cap 53 of the repeatedly used container 51 is formed. Then, as shown in Fig. 9, the positional relationship between the container 51 and the refill container 900 that are repeatedly used is kept constant, and the entire nozzle 832 is vertically lifted, and the container 900 is refilled at a time. The contents are poured into the container 51 which is reused.

As described above, the refill container 900 according to the embodiment of the present invention can ensure a large-area injection port without using a special plastic spigot or the like, and the size of the injection port can be matched with the target reusable container. The shape of the plug is freely designed, so it is of great value as a special refill container that can be quickly loaded and reloaded.

The laminated body 10 which forms the discharge nozzle 1032 is provided with a strip-shaped or rib-like relief 1035 which protrudes outward.

When the length of the predetermined opening line 1034 is E, the ridge 1035 has a center line 1035c of the ridge in a range of a distance of 2/3E from the injection nozzle sealing portion 1024a on the predetermined opening line 1034. Further, the ridges 1035 are present at least continuously from the predetermined unsealing line 1034 to the extension line 1025b of the dicing portion sealing portion 1025a.

The bent portion 6 is formed by bending one piece of the laminated body 10 at the top with the sealing layer 12 facing inward. The bent portion 6 forms an outflow path 1033 that reaches the contents of the injection port 1031 together with the injection nozzle sealing portion 1024a and the cutting portion sealing portion 1025a provided at the lower portion of the bent portion 6. By the elastic action of the laminated body 10 of the bent portion 6, the cross section of the outflow path 1033 always becomes the state of the upper inflated state. Therefore, the sectional area of the injection port 1031 can be broadly ensured. As a result, the refill container 1000 can discharge a large amount of contents at a time.

In the enlarged view of the injection nozzle 1032 shown in Fig. 21, the ridges 1035 are embossed outwardly with respect to the laminated body 10, and have a strip shape or a rib shape. The band shape refers to a rectangular shape, a trapezoidal shape, a semicircular shape, a semi-cylindrical shape, and the like, and the rib shape refers to a linear embossing having a triangular cross-sectional shape. The relief 1035 may not be linear, as long as it is continuous.

When the length of the predetermined opening line 1034 is E, the position of the center line 1035c of the ridge is present as a ridge 1035 in a range of a distance of 2/3 E from the injection nozzle sealing portion 1024a on the predetermined opening line 1034. The location is appropriate and this fact has been verified by the experiment. It is also understood that by providing the ridges 1035 in this range, the opening of the spout 1031 can be stably enlarged.

Further, it is preferable that the length of the ridge 1035 is at least continuously present on the extension line 1025b from the predetermined opening line 1034 to the cutting portion seal portion 1025a. As shown in Fig. 3, it is also possible to provide an extension line 1025b that greatly exceeds the cut portion 1025a of the cut portion.

Regarding the angle of the ridge 1035, the angle θ formed by the center line 1035c of the ridge 1035 and the ridge line 7 of the bent portion 6 is preferably 0 degrees or more and 60 degrees or less. When the angle θ is within this range, the effect of smoothing the opening of the injection port 1031 can be further improved.

In the embodiment shown in Fig. 19, the main body surface layer 2 and the main body back surface layer 3 are sealed in the side seal portion 22 and the bottom seal portion 23, and are formed in a bag shape. In the actual container, the filling opening for filling the contents is required. However, in the first drawing, the filling opening is omitted. In the embodiment shown in Fig. 19, the filling opening portion can be provided in the bottom seal portion 23 or the side seal portion 22.

Further, it is preferable that the predetermined opening line 1034 is a half-cut line which is continuously provided on the outer surfaces of the main body surface layer 2 and the main body back surface layer 3. With such a configuration, the portion of the predetermined opening line 1034 is torn by a hand, and the injection port 1031 can be easily formed. The half tangent is generally formed by a method of cutting by a knife and a method of forming by laser processing, but it is preferable to form a uniform and stable slit by a laser processing method. The type of laser is suitable for carbon dioxide gas lasers. The predetermined opening line 1034 does not need to be perpendicular to the ridge line 7 of the bent portion, and may be inclined.

The laminate 10 used in the refill container 1000 of the present embodiment can be used in the same general flexible package as the refill containers 1, 100, 200, 300, 400, 500, 600, 700, 800, and 900. The layered body 10.

Further, a notch 1036 is provided in the discharge nozzle 1032 of the refill container 900.

Fig. 22 is an enlarged view of the discharge nozzle of the refill container 1000 of the present embodiment, and is an explanatory view of the concave groove 1036. Between the ridge 1035 and the injection nozzle sealing portion 1024a, a strip-shaped or rib-like concave groove 1036 which is concave toward the outside is provided at a specific angle and at a specific position, so that the injection port 1031 and the outflow path can be secured more. The sectional area of 1033. Further, it is possible to eliminate the case where the dispensing nozzle 32 is bent or detached from the container that is repeatedly used, so that the refilling operation can be easily and quickly performed, and the effect can be stabilized. The main function of the concave groove 1036 is to improve the difficulty in the vicinity of the injection nozzle sealing portion 1024a of the injection port 1031, but it is also effective to prevent the bending of the injection port 1031.

The indentation 1036 has a concave center line 1036c within a range of less than 3 mm from the injection nozzle seal portion 1024a on the predetermined opening line 1034. Further, the indentations 1036 are present at least continuously on the extension line 1025b from the predetermined opening line 1034 to the cutting portion seal portion 1025a. Further, the concave groove 1036 is preferably in a range from the angle parallel to the injection nozzle sealing portion to the angle perpendicular to the ridge line 7 of the bent portion 6 at an angle of the center line 1036c of the concave portion. In Fig. 22, this angle range is represented by δ.

The shape of the concave groove 1036 is the same as that of the relief 1035, and its shape is a strip shape or a rib shape. Here, the strip shape means a cross-sectional shape of a rectangle, a trapezoid, a semicircle, a semi-cylindrical shape, or the like, and the rib-like shape refers to a linear embossing having a triangular cross-sectional shape. The concave groove 1036 is the same as the relief 1035, and may be a curve along the injection nozzle sealing portion 1024a as long as it is continuous or not straight.

Further, the relief 1035 and the indentation 1036 may not be in the form of a strip or a rib. Next, a description will be given of a variation of the relief 1035 and the indentation 1036 used in the refill container 1000 of the present embodiment, that is, the relief 1035A and the indentation 1036A.

The nozzles 1032A are each formed with a rib-like embossing to form a ridge 1035A and a dent 1036A. In the refill container 1000 of the present embodiment, even if it is an embossed shape of such a simple shape, the effect can be sufficiently exhibited. In particular, when paper is used as the laminated body 10 constituting the refill container 1000, it is preferable to use such a rib-like embossing from the viewpoint of preventing tearing of the paper.

Further, an example of such injection nozzles 1032, 1032A will be described with reference to Figs. 24A, 24B, 24C, and 24D.

Fig. 24A is a cross-sectional view showing an enlarged configuration of an example of a discharge nozzle 1032 of the refill container 1000. Fig. 24B is a cross-sectional view showing an enlarged configuration of an example of the dispensing nozzle 1032 of the refill container 1000. Fig. 24C is a cross-sectional view showing an enlarged configuration of an example of the dispensing nozzle 1032A of the refill container 1000. Fig. 24D is a cross-sectional view showing an enlarged configuration of an example of the dispensing nozzle 1032A of the refill container 1000A.

In the example of the dispensing nozzle 1032 shown in Fig. 24A, the dispensing nozzle 1032 is provided with a strip-shaped relief 1035 having a trapezoidal cross-sectional shape and a strip-shaped concave 1036 having a trapezoidal cross-sectional shape.

In the example of the dispensing nozzle 1032 shown in Fig. 24B, only the strip-shaped relief 1035 having a trapezoidal cross-sectional shape is provided. As described above, the injection nozzle 1032 may have a configuration without the indentation 1036 as long as the sectional area of the injection port 1031 can be secured.

In the example of the dispensing nozzle 1032A shown in Fig. 24C, a rib-like ridge 1035A having a triangular cross-sectional shape and a rib-like concave 1036A having a triangular cross-sectional shape are provided.

Further, in the example of the dispensing nozzle 1032A shown in Fig. 24D, only the strip-shaped relief 1035A having a trapezoidal cross-sectional shape is provided. As described above, the injection nozzle 1032A may have a configuration without the concave groove 1036A as long as the sectional area of the injection port 1031 can be secured.

Next, a refill container 1100 according to a twelfth embodiment of the present invention will be described in detail with reference to Figs. 25, 26A, and 26B. The same components as those of the above-described respective refill containers 1, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Fig. 25 is a schematic view showing the configuration of a refill container 1100 according to a twelfth embodiment of the present invention. Fig. 26A is a cross-sectional view schematically showing the configuration of a cross section taken along the line XXVI-XXVI of the container 1100 for the same weight loading. Fig. 26B is a cross-sectional view showing a state in which the XXVI-XXVI cross section of the container 1100 for the same weight loading, that is, the state in which the container 1100 for unsealing is filled.

As shown in Figs. 25, 26A, and 26B, the refill container 1100 of the present embodiment is formed by folding a laminated body 10 having at least a base material 11 and a sealing layer 12 so that the sealing layer 12 faces outward. The bottom tape 4 is inserted between the body surface layer 2 and the body back surface layer 3 and is formed by sealing the periphery. Thus, the refill container 1100 is formed into a pouch shape.

Further, the refill container 1100 has the bent portion 6 similarly to the refill container 1000. The bent portion 6 forms a discharge nozzle 1032 for injecting a content together with the injection nozzle sealing portion 1024a and the cutting portion sealing portion 1025a.

In the case of such a shape, the refill container 1100 cannot provide the filling opening for filling the contents in the side seal portion. Therefore, one of the bent portions 6 is cut as the filling opening portion 1141. In the embodiment shown in Fig. 25, the filling opening 1141 is sealed to become the top sealing portion 1121. As described above, when the filling opening portion 1141 is present on the top of the refill container 1100, there is an advantage that the filling operation of the contents can be easily performed.

As shown in Fig. 26B, the vertical bag container 1100 in the form of a pouch has a wide base tape 4, so that a large-capacity container can be easily formed. Thereby, the feature of the injection time of the refill container 1100 of this embodiment can be fully utilized.

The bent portion 6 is formed by bending one piece of the laminated body 10 at the top with the sealing layer 12 facing inward. The bent portion 6 forms an outflow path 1033 that reaches the contents of the injection port 1031 together with the injection nozzle sealing portion 1024a and the cutting portion sealing portion 1025a. According to this configuration, in particular, when the content is liquid, the contents can be smoothly flowed to the linear outflow path 33 when the contents are ejected, so that the contents can be quickly ejected. Thereby, since the refill container 1100 has a large container capacity, further effects are obtained.

Next, a refill container 1200 according to a thirteenth embodiment of the present invention will be described in detail with reference to FIG. The same components as those of the above-described respective refill containers 1, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, and 1100 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Figure 27 is a schematic view showing the configuration of a refill container 1200 according to a thirteenth embodiment of the present invention.

The refill container 1200 is provided with a handle 1226 that can be accommodated in the shape of the cutting portion 1225 on the side opposite to the cutting portion 1225 on which the nozzle nozzle portion 1024a of the dispensing nozzle 1032 is formed. The cutting processing portion 1225 is formed by the injection nozzle sealing portion 1224a, and the outflow path 1033 is formed as the protruding injection nozzle 1032. The shape of the cut processing portion 1225 can be selected in accordance with the structure of the periphery of the plug portion of the container 51 to be reused.

In order to manufacture the refill container 1200 shown in Fig. 27, the laminated body 10 having a width twice the width of the height of the refill container 1200 is cut to the top of the sealing layer 12 so as to face the inside. The bend is made to face the body layer body 2 and the body back surface layer body 3. Then, the laminated body 10 is continuously provided, and the bottom tape 4 which is folded into two in such a manner that the surface of the sealing layer 12 faces outward is continuously provided therebetween. After the supply, after the necessary sealing, the container 1200 is formed into a refill container by cutting.

The cutting processing portion 1225 is originally a discarding portion. As shown in Fig. 27, if the handle 1226 is designed to be accommodated in the shape of the cutting processing portion 1225 of the adjacent refill container 1200, no special material is added. A handle 1226 can be attached. By the presence of the handle 1226, the handle 1226 can be held by hand to perform a refill operation. Therefore, the refilling operation can be performed more safely and simply using the refill container 1200.

Further, the refill container 1200 cuts a part of the bent portion 6 to form a filling opening portion 1241 for filling the contents. In the present embodiment, since the side seal portion 22 has the cut processing portion 1225 and the handle 1226, it is difficult to provide the filling opening portion 1241 having a sufficient width outside the bent portion 6. Therefore, the position of the opening portion 1241 for filling is preferably provided in the bent portion 6.

6 to 8 are schematic views showing an example of a series of refilling operations using a refill container 1200 according to an embodiment of the present invention. As shown in Fig. 6, after the heavy-fill container 1200 of the present embodiment is held, the front end of the injection nozzle 1032 is cut off to open the injection port 1031. The nozzle 52 of the container 51 which has been used up and reused is inserted into the injection port 1031. In the figure, the container 51 that is repeatedly used is a plastic container having a nozzle cap 53 having a nozzle 52.

Next, as shown in Fig. 7, a state in which the discharge nozzle 1032 of the refill container 1200 is surely inserted into the nozzle cap 53 of the repeatedly used container 51 is formed. Then, as shown in Fig. 8, the positional relationship between the repeatedly used container 51 and the refill container 1200 is kept constant, and the entire nozzle 1032 is vertically lifted, and the container 1200 is refilled at a time. The contents are poured into the container 51 which is reused.

As described above, in the refill container 1200 according to the embodiment of the present invention, it is possible to secure a large-area injection port 1031 without using a special plastic spigot or the like. Further, since the size of the injection port 1031 can be freely designed in accordance with the shape of the plug of the target reusable container 51, it is extremely valuable as a dedicated refill container which can perform a rapid heavy loading operation.

Next, with respect to the refill container 1200 of the present embodiment, the sixteenth embodiment and the seventeenth embodiment will be described as a specific example, and the comparative example 9 of the refill container 1200 and the comparative example 9 will be described. Description.

PET (Dongli company product P60; 12μm) / printing layer / adhesive layer (Toyo Morton products TM272; 3g / m ² (dry)) / ONY (UNITIKA company products ONMB; 15μm) / adhesive layer (ibid) / LLDPE (TOCELLO company TUX-FCS; 150μm)

As the base tape, the laminated body 10 formed by the following structure is used.

<Configuration of the laminated body 10 for the base tape 4>

ONY (UNITIKA company ONM; 25μm) / LLDPE (same as above; 120μm)

Using the above laminated body 10, a stand-up pouch having the shape shown in Fig. 27 was produced. The size of the stand is 150mm in width and 272mm in height. It is noted that the embossing of the nozzle 1032 is only the relief 1035, and the indentation 1036 is not provided. The relief 1035 has a trapezoidal cross-sectional shape and a height of 1 mm, a length of 40 mm, and an angle θ of 50 degrees.

As the filling opening portion 1141, one of the bent portions 6 is cut out and used as the filling opening portion 1141. Further, the predetermined opening line 1034 of the injection port 1031 which is to be the end portion of the nozzle 1032 is designed to be a half-cut line formed by laser processing. 900 g of the liquid detergent was filled in the refill container 1200 thus obtained, and the filling opening 1141 was heat-sealed to obtain a test object for evaluation.

(Example 17)

A container for evaluation was prepared in the same manner as in Example 16 except that the relief 1035 was provided in the discharge nozzle 1032, and the groove 1036 was provided, and the same contents were filled. The cross-sectional shape of the concave groove 1036 is trapezoidal, and has a height of 1 mm, a length of 30 mm, and an angle δ of 35 degrees.

(Comparative Example 9)

The evaluation container was prepared in the same manner as in Example 1 except that the embossing was not provided in the discharge nozzle, and the same contents were filled.

The tip end of the dispensing nozzle 1032 of each of the evaluation test bodies (refill container 1200) was torn by hand along the predetermined opening line 1034, and the time required for the contents to be ejected was evaluated. Tables 3 and 28 show the results of these experiments. Further, the time marked in Table 3 is the time required for the ejection of 95% of the content amount.

As can be seen from Tables 3 and 28, the ejection time can be shortened by providing the relief 1035 by the nozzle 1032. Further, when the indentation nozzle 1032 is provided with the indentation 1036, the ejection time can be further shortened.

Further, not only the refill container 1200 has the ejection nozzle 1032, but also the refill container 1000, and the 1100 also has the ejection nozzle 1032. Therefore, the refill container 1000, 1100 can also be obtained the same as the refill container 1200. The effect.

The refill container of the present invention comprises a laminate having at least a base material and a seal layer, and includes a main body back surface layer body and a body back area layer body, and the seal layers are opposed to each other to form a surrounding seal. Therefore, unlike a plastic bottle or a container using a plastic plug, it can be manufactured only by a laminate for a flexible package, and therefore, it can be manufactured at low cost.

Further, in the refilling container, a laminated body is bent at the top with the sealing layer facing inward to form a bent portion, the body surface layer body, and the body back surface layer body. The bent portion forms an outflow path that reaches the contents of the injection port in a horizontally long manner together with the injection port sealing portion provided at the lower portion thereof, thereby forming a discharge nozzle (outflow path) for discharging the internal contents. Therefore, a large-area linear outflow path can be stably ensured, and as a result, a smooth and rapid heavy loading operation can be performed. In addition, the injection port can be formed easily and surely.

Further, the injection port is formed by cutting the front end of the discharge nozzle along a predetermined opening line, and when the length of the predetermined opening line is A (mm) and the width of the opening of the injection port is B (mm), The following relationship is satisfied: A-4 (mm) ≦ B (mm) ≦ A - 0.5 (mm). Thereby, the width of the opening portion can be made wider with respect to the length of the predetermined opening line, so that it can be easily inserted into the nozzle cap portion of the container body to be reused. In addition, the flow rate at the time of dispensing can be ensured, so that the refilling operation can be performed stably and quickly.

Further, along a predetermined cutting line and then cut by the front end of the outflow path is formed of the spout, the spout is provided in the width A (mm), when B (mm ²⁾ cross-sectional area of the opening portion of the spout to meet the following The relationship is: 1/10 × (A ² / π) (mm ² ) ≦ B (mm ² ) ≦ A ² / π (mm ² ). Thereby, the cross-sectional area of the opening portion can be ensured to be wide, so that it can be easily inserted into the nozzle cap portion of the reusable container body. In addition, the flow rate at the time of dispensing can be ensured, so that the refilling operation can be performed stably and quickly.

Further, the refilling container is provided with a belt-like or rib-like ridge protruding toward the outside at a specific position of the laminated body forming the injection nozzle, whereby the injection port and the outflow path can be largely ensured. area. In addition, there is no case where the nozzle is bent or peeled off from the reused container.

Thereby, the refilling operation can be performed easily and quickly. In this case, when the angle formed by the ridge line of the bent portion and the center line of the ridge is 0 degrees or more and 60 degrees or less, the feature can be further sufficiently exhibited.

Further, when the ridge and the injection nozzle sealing portion are provided with a band-shaped or rib-like concave groove that is concave toward the outside at a specific angle, the injection port and the outflow path can be largely ensured. The area of the section. At the same time, there is no case where the nozzle is bent or peeled off from the reused container. Therefore, the effect of the refilling container which can easily and quickly perform the refilling operation can be more stabilized.

Further, the refill container has a main body surface layer, a main body back surface layer, and a bottom tape, and the respective sealing layers are opposed to each other to form a surrounding seal. Further, the base tape 4 is formed by at least one laminated body of the base material and the sealing layer, which is bent at the lower portion of the container so that the sealing layer faces outward. By inserting the bottom tape between the body surface layer body and the body back surface layer body and sealing the periphery, one end of the bottom tape and the body surface layer layer, and the other end and the body back area layer body respectively form a bottom sealing portion to form a bottom surface of the container , that is, made into a so-called standing bag. In the case where the refill container is configured as a stand pouch, it is possible to form a refill container having a large capacity of self-standing property, and the effect of the refill container can be fully utilized.

In the case where the discharge port is formed by the injection port sealing portion and the outflow path is formed as a protruding injection nozzle, the injection nozzle can be inserted into the inside of the socket of the reusable container, so that such an operation can be performed. The container works.

In the case where the injection-out portion is formed by the injection-outlet sealing portion and the outflow path is formed as a protruding injection nozzle, the shape of the injection nozzle of the nozzle cap of the container body to be reused can be achieved, so that the nozzle can be more smoothly Perform a refill operation.

In the case where a handle that can be accommodated in the cut processing portion is provided on the side opposite to the cut processing portion that forms the discharge port sealing portion of the discharge nozzle, the handle can be held for the refilling operation. Therefore, the refilling operation can be performed more safely and easily. Since the handle is a shape that can be accommodated in the cutting processing portion, waste of the laminated body does not occur when punching from a continuous laminated body.

Further, in the case where the half-cut line is provided on the outer surface of the body surface layer and the body back surface layer which are part of the injection port, the half-cut line is torn by the hand, and the injection port can be easily opened. Similarly, in the case where the predetermined opening line is a half-cut line provided on the outer surface of the body surface layer body and/or the body back surface layer body, the half-cut line can be opened by hand to easily open the sealing port.

On the predetermined opening line, by performing the half-cut processing by laser or the like, the correct opening along the predetermined opening line can be easily performed.

In addition, in the case where one of the bent portions is cut as the content filling opening portion, a stable filling operation can be performed even in a container in which the other sealing portion cannot be used as the filling opening portion.

In the case of the refill container of the present invention, when the nozzle of the reusable container having the nozzle cap can be inserted into the injection nozzle, the nozzle of the reusable container is inserted into the horizontally held injection nozzle, and the injection nozzle becomes The container is tilted in a vertical manner. Thereby, it is possible to constitute a refill container which can be quickly reloaded, and the effect of the present invention can be maximized.

That is, the refill container of the present invention allows the injection port to be naturally opened by the presence of a bent portion in which a laminated body is loosely bent, so that it can be easily inserted into the nozzle of the target container. In addition, by designing the size of the injection port by fitting the nozzle, it is possible to form a discharge port that completely conforms to the size of the nozzle. Therefore, after the nozzle of the reusable container is inserted into the horizontally held injection nozzle, the injection nozzle is inclined so as to be vertical, whereby the refilling operation can be quickly performed.
