Description

  The present invention relates to a method for producing a container suitable for extruding contents by a required amount using a simple extruder such as an extrusion gun.

  The paint is generally contained in a relatively rigid container such as a metal can and is commercially available. However, according to such a container, the bulk of the paint is constant before and after use, so it is difficult to secure an inventory space before production, and the cost required for processing based on the Container Recycling Law becomes high. there were. In addition, since it is difficult to ensure transparency in the container as described above, the color of the paint contained therein is generally indicated by a printed color separately. There was also a problem that the desired color was different from the actual color of the purchased paint.

  Furthermore, when applying the paint contained in the container as described above, it is common to apply the paint using a roller or a brush after transferring the paint once to another container. Due to the poor workability, there were also problems that the hands became dirty and that many items were washed after application.

  In order to improve workability, a technique is known in which paint is directly fed by a pressurizer such as an air pump to a rotor or brush provided with a paint discharge port via a paint transport pipe such as a tube. According to such a technique, although the work efficiency is improved, the power supply is used, the apparatus becomes large, and the operability is poor, so that the application cannot be easily performed at home.

  Japanese Patent Application Laid-Open No. 2001-149849 discloses a technique in which a coating material is accommodated in a cartridge and an extrusion gun such as a commercially available caulking gun is used for application. Specifically, as shown in FIG. 12 (A), a cartridge 101 for containing paint, a rigid tube 103 connected to one end of the cartridge 101 for supplying paint to a roller 102 described later, A cartridge-type paint roller is described which includes a roller 102 rotatably attached to the distal end of the rigid tube 103 and an extruder 105 for pumping paint. In particular, as shown in FIG. 12 (B), the cartridge 101 is provided with an opening 108 at one end thereof, and the opening 108 is pressed from the outside so that the cartridge 101 extends in the depth direction of the cartridge. A sealing member 104 that can be slid along the inner side surface and fitted is fitted. That is, the cartridge 101 is made of a material having such a high rigidity that the sealing member 104 can slide in the cartridge 101 by external pressure. A protrusion is formed integrally with the cartridge 101 at the other end of the cartridge 101, and a male screw 107 for connecting to the rigid tube 103 is formed on the outer surface thereof. The tip of the protrusion is cut by a cutting means such as a nipper to open a hole 106, thereby forming a passage through which the paint supplied from the cartridge passes.

  In such a cartridge-type paint roller, the paint contained in the cartridge 101 is pushed out to the rigid tube 103 by pressing the sealing member 104 by the extruder 105 and further supplied to the roller 102. The roller 102 has a configuration capable of absorbing the supplied paint, and the roller 102 is pressed against an object and rotated to rotate the paint so that the paint oozes onto the roller surface and can be applied. .

  Although the conventional cartridge 101 used for the cartridge type paint roller improves the workability and operability at the time of application, the bulk is constant before and after the use of the paint, and therefore it is difficult to secure an inventory space before production. In addition, there is still a problem that the cost required for processing based on the Container Recycling Law becomes high. In addition, the cartridge 101 needs to be hermetically mounted so that the paint does not leak from between the sealing member 104 and the inner wall of the cartridge 101 when the sealing member 104 is pressed. There was a problem of high cost.

  The present invention has been made in view of the above circumstances, that is, as compared with a conventional cartridge, the empty container can be easily processed, its processing cost can be greatly reduced, and the manufacturing cost can be reduced. An object of the present invention is to provide a method for producing a container capable of extruding the contents using a simple extruder such as an extrusion gun with the same workability and operability as a conventional cartridge.

The present invention includes a step of arranging a deformed hexagonal film 11c in a folded state on one end of two substantially rectangular films 11a and 11b,
A process of fusing the entire circumference of the deformed hexagonal film 11c to the substantially rectangular film 11a and the substantially rectangular film 11b; A step of fusing the film 11a and the substantially rectangular film 11b;
It is related with the manufacturing method of the container characterized by the above-mentioned.

  The container of the present invention can store the contents in a sealed state. In addition, the container of the present invention can push out the liquid as a content by a required amount with the same workability and operability as a conventional cartridge, and can push out the liquid almost without any excess. In addition, since the main body portion of the container of the present invention is a flexible pouch, the bulk after the contents are pushed out is significantly smaller than when a conventional cartridge is used, greatly increasing the cost required for processing. Can be reduced. Furthermore, the container of the present invention has a simple structure, and in particular, the extrusion port does not need to be formed integrally with the pouch, but is formed separately and only needs to be attached to the pouch immediately before use. Cost can also be significantly reduced.

  The container of the present invention comprises a pouch and an extrusion port. Specifically, as shown in FIG. 1, the pouch 1 is formed by forming a film-like material into a bag shape, and is attached to one end of a cylindrical portion 4 having an external thread formed on the outer peripheral surface thereof. It consists of the extrusion port 2 in which the flange part 5 is formed. FIG. 1 is a perspective view showing a state immediately before a container of the present invention containing liquid is loaded into an extruder. The extrusion port 2 may be attached to the pouch 1 immediately before use.

  In FIG. 1, a pouch 1 is a ship-bottomed pouch. As shown in FIG. 2A, a deformed hexagonal film 11c is arranged at one end of two substantially rectangular films 11a and 11b, and the film 11c. Are fused to the film 11a or 11b, and the films 11a and 11b are fused at the edges of the films 11a and 11b. A cross-sectional view along BB in FIG. 2A is shown in FIG. 2A and 2B, the fusion part is indicated by M.

  When filling the pouch 1 with the liquid, the end opposite to the end where the film 11c of the films 11a and 11b in FIG. 2A is disposed is left unfused, and the liquid is filled from there. Thereafter, the end portion may be fused to seal the inside of the pouch. In a state where the inside of the pouch is hermetically sealed, the film 11c is substantially flat, and an extrusion port 2 described later can be easily attached.

  In FIGS. 1 and 2, a ship bottom type pouch is shown as the pouch 1, but the present invention is not limited to this, and any form can be used as long as it is a flexible pouch capable of attaching the extrusion port 2 to one end side. It can be a pouch. For example, in FIG. 2A, a standing pouch having the same configuration as that shown in FIG. 2A, except that the deformed hexagonal film 11c is disposed on both ends of two substantially rectangular films 11a and 11b. In addition, known types of pouches such as a tube type, an envelope type, a back sticking type, a GZ type, and a modified three-way type may be mentioned.

  The film-like material forming the pouch 1 has such flexibility that the pouch can be easily deformed by pressing by an extruder and the contents in the pouch can be pushed out, and the contents in the pouch are in a sealed state. The material is not particularly limited as long as the material can ensure the accommodation. Examples of such film-like materials include polyamide resin film, low density polyethylene resin film, high density polyethylene resin film, polypropylene resin film, polyethylene terephthalate resin film, ethylene / vinyl alcohol copolymer resin film, and polyvinylidene fluoride. Examples thereof include unstretched films such as fluorinated resin films and stretched films thereof (uniaxial and biaxially stretched films). These films may have a vapor deposition layer such as ceramic and / or an aluminum foil layer. Moreover, the said film may be used independently, or may be used as a laminated film formed by laminating two or more films.

  When the content is a water-based paint, the film material is not particularly limited, but is preferably a highly transparent polyethylene resin film from the viewpoint of color visibility of the content.

  When the content is oil-based or solvent-based paint, liquid crystal, grease, etc., the film-like material is made of an aluminum foil layer, a transparent vapor-deposited polyethylene terephthalate resin layer (polyethylene) from the viewpoint of gas barrier properties, water vapor barrier properties and / or solvent resistance. (Terphthalate resin layer deposited with ceramic, etc.), transparent deposited polyamide resin layer (polyamide layer deposited with ceramic, etc.), composite stretched polyamide resin layer, composite stretched polypropylene resin layer, ethylene / vinyl alcohol A laminated film including at least one layer selected from the group consisting of a fluorinated polyethylene resin layer such as a polymer resin layer and a polyvinylidene fluoride resin layer and a high-density polyethylene resin layer is preferable. At this time, the other material constituting the laminated film is not particularly limited, and examples thereof include at least one layer selected from the group consisting of a stretched polyamide resin layer, a low density polyethylene resin layer, and an unstretched polypropylene resin layer.

  Specific examples of preferred laminated films when the contents are oil-based and solvent-based paints, liquid crystals, greases and the like include, for example, (1) a stretched polyamide resin layer on one side of an aluminum foil layer and a low-density polyethylene resin layer on the other side Or a laminated film formed by laminating an unstretched polypropylene resin layer, (2) a stretched polyamide resin layer on one side of a transparent vapor-deposited polyethylene terephthalate resin layer or a transparent vapor-deposition polyamide resin layer, and a low-density polyethylene resin layer or unstretched on the other side A laminated film formed by laminating a polypropylene resin layer, (3) a laminated film obtained by laminating a low density polyethylene resin layer or an unstretched polypropylene resin layer on one side of the composite stretched polyamide resin layer, and (4) a composite stretched polypropylene resin layer. Laminated low-density polyethylene resin layer or unstretched polypropylene resin layer on one side (5) A laminated film obtained by laminating a stretched polyamide resin layer on one side of an ethylene / vinyl alcohol copolymer resin layer and a low-density polyethylene resin layer or an unstretched polypropylene resin layer on the other side, 6) Laminated film formed by laminating stretched polyamide resin layer on one side of aluminum foil layer and high density polyethylene resin layer on the other side, (7) Laminating low density polyethylene resin layer on one side of polyvinylidene fluoride resin layer The laminated film etc. which are formed are mentioned.

In particular, when the contents are oil-based and solvent-based paints, the film material is more preferably the laminated film of (6) or (7) among the above specific examples.
Moreover, when the content is a liquid crystal, the film-like material is more preferably the laminated film of the above (2) among the above specific examples.
When the content is grease, the film material is more preferably a laminated film of (1), (2), (3) among the above specific examples.

  The film-like material as described above can use a colorless and transparent film as a film (all films (layers) constituting the laminated film in the case of using a laminated film). In some cases, the user can check the actual color of the paint at the time of purchase. Further, even when the content is liquid crystal, the color of the liquid crystal can be determined from the outside during use, so that the progress of deterioration of the liquid crystal can be easily confirmed.

  Since the pouch as the main body portion of the container of the present invention is formed from the flexible film-like material as described above, the required amount of liquid as the content is obtained with the same workability and operability as the conventional cartridge. The liquid can be pushed out and the liquid can be pushed out almost without any excess. In addition, the bulk after the contents are pushed out is significantly smaller than when a conventional cartridge is used, and the cost required for processing can be greatly reduced.

  The extrusion port 2 is attached to one end of the pouch 1 for guiding the contents in the pouch to the outside, and is generally a resin injection molded body. In detail, as shown in FIG. 3, it has the shape by which the flange part 5 affixed with respect to the said pouch 1 was formed in the one end part of the cylindrical part 4 in which the external thread 3 was formed in the outer peripheral surface. The flange portion 5 is attached to one end portion of the pouch 1. In particular, an adhesive layer 7 for being attached to the pouch 1 is laminated on the surface of the flange portion 5. The external thread 3 engraved on the outer periphery of the cylindrical portion 4 can connect an application member to be described later for applying the content pushed out from the pouch 1 to the object. FIG. 3 is a schematic sectional view of the vicinity of the extrusion port 2 in FIG. 3, 6 shows the inner position of the cylindrical part 4 of the extrusion port 2 in the pouch 1, and the pouch 1 is perforated at the position after the extrusion port 2 is adhered.

  The container of the present invention as described above has a simple configuration, and in particular, the extrusion port 2 does not need to be formed integrally with the pouch, but is formed separately and may be attached to the pouch immediately before use. The manufacturing cost can be significantly reduced.

  The liquid accommodated in the container of the present invention is not particularly limited as long as it is a liquid material having fluidity, but it is possible to use various application members described later to expand the variation of the application method of the liquid to the object. To low or medium viscosity liquid. When a liquid having a too high viscosity is used, usable application members are limited, and for example, an application roller described later cannot be used.

Specific examples of the low-viscosity or medium-viscosity liquid include paints, liquid crystals, greases, oils, printing inks, pigment solutions, and the like, and paints are particularly effective.
The paint shall be used in a concept including all liquid materials that can form a film (the film thickness is not particularly limited) on the surface by evaporation of the solvent after being applied to the surface of the object. It may be a water-based paint using water as at least one component, or may be an oil-based or solvent-based paint that does not use water as a solvent.
Among the liquids, an aqueous paint is preferable from the viewpoint of easy handling.

  An example of an extruder to which the container of the present invention can be attached is the extrusion gun shown in FIG. 4A and 4B are explanatory views of the structure of a commercially available extrusion gun 8, wherein FIG. 4A is an external view, and FIG. The extrusion gun shown in FIG. 4 is a hermetically sealed type. The cylinder 21 is open at both ends, the lid 22 is detachably attached to one end of the cylinder 21, and the small opening 22 a is formed. The piston 23 is configured to be movable, a trigger mechanism 24 that moves the piston 23, and a support member 25 that supports the rod 23 and the trigger mechanism 24 of the piston 23 and closes the other end of the cylinder 21. ing. Reference numeral 26 denotes a guide fitted so as to be movable relative to the rod of the piston 23. When the cylinder 21 is made of transparent plastic, there is an advantage that the inside can be seen and the amount used can be confirmed and the color of the paint used can be seen. Also, if the scale is attached to the cylinder, the amount used can be determined more accurately.

  In use, first, the extrusion port 2 is adhered to the adhesive layer 7 of the flange portion 5 at the substantially central portion of the film 11 c on one end side of the pouch 1. Next, the lid body 22 of the extrusion gun 8 is removed, the above-mentioned extrusion port sticking pouch is inserted into the cylinder 21, the lid body 22 is mounted, and the extrusion port 2 is exposed from the small opening 22a. The state at this time is shown in FIG.

  After the lid 22 is mounted, the punch 22 is perforated by breaking the inner position of the extrusion port 2 cylindrical portion 4 in the pouch 1 with a suitable stick or the like. As shown in FIG. 6, the pouch 1 is perforated by a cup-shaped lid body 30 with one end opened, and an internal thread 30a is formed on the inner peripheral surface of the internal thread 30a. You may carry out by screwing into the extrusion port 2 the cover body 30 by which the piercing stick | rod 30b with a sharp front-end | tip protruded from the open end. Such a lid 30 also has a function as a lid that prevents deterioration of the contents by attaching the extrusion member 2 after removing an application member described later when storing the remaining contents.

  After attaching the extrusion port sticking pouch to the extruder and perforating the pouch, the application member is attached to the extrusion port 2.

  An application member is for applying the content extruded from the pouch 1 through the extrusion port 2 to a target object. The application member is determined depending on the use of the contents contained in the pouch, and may be any form of member as long as the application member can be connected to the extrusion port so that leakage of the contents does not occur. Specific examples include a coating roller, a coating brush, a dispensing nozzle, a screen printing squeegee, and the like.

  For example, as shown in FIG. 7 (A), the application roller is connected to one end of the cylindrical portion 31 having an inner peripheral surface formed with a female screw that is screwed into the male screw of the extrusion port, It comprises a hard transport pipe 32 for transporting the extruded liquid, and a roller section 33 that is rotatably attached to the other end of the hard transport pipe 32 and applies the transported liquid to an object. The roller part 33 has a structure that can absorb the liquid that has been transported, and by pressing the roller part 33 against the object and rotating the roller, the contents ooze onto the roller surface and can be applied. It has become.

  When the application roller is attached to the extrusion port of the container of the present invention that is attached to the extruder and perforated, the trigger 24 is operated and the piston 23 is moved to the lid 22 side, the pouch 1 is moved inside the cylinder 21. Since it is pressed, the contents of the pouch 1 are pushed out to the transport pipe by the required amount through the extrusion port 2 and further transported to the roller portion 33. The contents transported to the roller unit 33 are absorbed by the roller, and the roller can be applied.

  In another aspect of the application roller, as shown in FIG. 7B, the soft transport pipe 34 and the grip part 35 are not interposed between the cylindrical part 31 and the hard transport pipe 32. A structure similar to the structure shown in FIG. That is, the application roller includes a cylindrical portion 31 having an inner peripheral surface formed with a female screw that is screwed into a male screw of an extrusion port, and is connected to the cylindrical portion 31 at one end and is soft for transporting the extruded liquid. A transport pipe 34, a grip part 35 attached to the other end of the soft transport pipe 34 and having a liquid flow path therein, and a rigid transport pipe connected to the grip part 35 at one end to transport the extruded liquid 32, and a roller portion 33 that is rotatably attached to the other end of the rigid transport pipe 32 and applies the transported liquid to an object. By adopting such a configuration in which the soft transport pipe is interposed, not only can the operability be improved and the contents can be applied more easily, but also the applicable member applied to the sticking site of the extrusion port 2 in the pouch 1. The load due to can be reduced. In such an embodiment, the trigger may be operated by holding the extruder with one hand and the grip part may be held with the other hand.

  For example, as shown in FIG. 8, the coating brush is connected to the cylindrical portion 41 having an internal thread formed on the inner peripheral surface thereof to be engaged with the male screw of the extrusion port. It consists of a hard transport pipe 42 for transporting the liquid, and a brush part 43 connected to the other end of the hard transport pipe 42 for applying the transported liquid to the object. The brush part 43 has a flow path in the handle part 45 for supplying the transported liquid to the application part 44.

  When the application brush is attached to the extrusion port of the container of the present invention attached to the extruder and perforated, the trigger 24 is operated and the piston 23 is moved to the lid 22 side, the contents of the pouch 1 are pushed. The required amount is pushed out to the transport pipe through the outlet 2 and further transported to the brush portion 43, where the brush can be applied.

  In another aspect of the application brush, the configuration shown in FIG. 8 except that a soft transport pipe is used instead of the hard transport pipe 42 for the same reason as in the other aspect of the application roller shown in FIG. You may have the structure similar to. That is, the coating brush has a cylindrical portion 41 having an inner peripheral surface formed with a female screw that is screwed into a male screw of an extrusion port, and is connected to the cylindrical portion 31 at one end and is soft for transporting the extruded liquid. It is composed of a transport pipe and a brush portion 43 that is connected to the other end of the soft transport pipe and applies the transported liquid to an object. In such an embodiment, the application may be performed by holding the extruder with one hand and operating the trigger and holding the handle 45 with the other hand.

  For example, as shown in FIGS. 9 (A) and 9 (B), the dispensing nozzle has a cylindrical portion (51, 61) in which an internal thread is formed on the inner peripheral surface to be engaged with the external thread of the extrusion port. It consists of nozzle parts (52, 62) connected to the shaped parts (51, 61) and for pouring the extruded liquid into a predetermined part. FIG. 9A is a cross-sectional view of a dispensing nozzle in which the nozzle portion 52 has a cone shape. The cone-shaped nozzle portion 52 is closed when the tip portion is not used, and is opened by cutting at a position corresponding to the desired extrusion diameter of the contents and the content extraction portion. FIG. 9B is an external view of a dispensing nozzle in which the nozzle portion 62 has a flat shape. By appropriately selecting and using such a dispensing nozzle in accordance with the content extraction site, the content can be accurately extracted to a predetermined site.

  In another aspect of such a dispensing nozzle, a soft or hard transport pipe is disposed between the cylindrical portion (51, 61) and the nozzle portion (52, 62), as shown in FIG. You may have the structure similar to the structure shown to A) and (B). That is, the pouring nozzle is connected to one end of the cylindrical portion (51, 61) having an internal thread formed on the inner peripheral surface thereof to be screwed with the male screw of the extrusion port, and is pushed out. A soft or rigid transport pipe (not shown) for transporting the transported liquid, and a nozzle part (52, 62) connected to the other end of the transport pipe for pouring the transported liquid to a predetermined site It is made up of. Thus, by taking the structure which a transport pipe interposes, the content can be poured out more correctly to a predetermined part. In particular, when a soft transport pipe is interposed, the operability is further improved and the contents can be poured out more easily. In this case, it is only necessary to operate the trigger by holding the extruder with one hand and perform the pouring with the nozzle part with the other hand.

  In another embodiment of the dispensing nozzle shown in FIGS. 9A and 9B, the nozzles (51 and 52 or 61 and 62) may be integrated with the aforementioned extrusion port 2. That is, in the above-described aspect, the dispensing nozzles (51 and 52 or 61 and 62) and the extrusion port 2 are used as separate members, but when the pouch is mounted on the extruder, the nozzle and the extrusion port are separated. An extrusion port with a nozzle may be used in place of the extrusion port 2 as long as the integrated one (extrusion port with a nozzle) can face the small opening of the lid. In this case, after attaching the nozzle-extruding port to the pouch 1 and attaching the nozzle to the extruder, and then drilling the pouch, a long tool such as a screwdriver may be used from the nozzle opening.

  The screen printing squeegee is for extending the ink supplied on the printing screen widely. For example, as shown in FIG. 10A, the internal thread has an internal thread that is screwed into the external thread of the extrusion port. The formed cylindrical part 71, connected to the cylindrical part 71 at one end, the soft transport pipe 72 for transporting the extruded liquid, and the liquid transported connected to the other end of the soft transport pipe 72 Is formed of a squeegee portion 73 for thinly spreading on the object (screen). As shown in FIGS. 10A to 10C, the squeegee unit 73 is formed with a flow path 74 and a discharge port 75 for supplying the transported liquid to an object (screen). 10A is an external view of a screen printing squeegee, FIG. 10B is an XX cross-sectional view in FIG. 10A, and FIG. 10C is a YY cross-sectional view in FIG. 'Cross sectional view, YY sectional view and Y'-Y' sectional view are common.

  When the cylindrical portion 71 of the squeegee for screen printing is attached to the extrusion port of the container of the present invention that is attached to the extruder and perforated, the trigger 24 is operated to move the piston 23 toward the lid body 22 side. The content (ink) 1 is extruded through the extrusion port 2 to the transport pipe in a required amount, and further transported to the squeegee unit 73 so that it can be continuously printed without supplying ink separately during screen printing. Become.

  When various application members as described above are attached to the extrusion port of the container of the present invention and the contents in the container are applied to the object, almost all the contents can be finally extruded. After the contents have been used up in this way, the pouch 1 has a thickness of about several millimeters in the original axial direction, and the volume of the empty container is several tenths compared to the case of using a conventional cartridge. Processing costs can be greatly reduced.

  The container of the present invention can store the contents in a sealed state in a pouch. For this reason, the pouch is marketed with the contents contained in a sealed state, with the extrusion port 2 shown in FIGS. 1 and 3 attached, or with the extrusion port 2 and the application member attached. Further, it may be commercially available with an extruder attached. The extrusion port 2 and the application member may be sold separately.

  In the above description, a case where a closed type extrusion gun is used as an extruder has been described. However, in the present invention, as an extruder, in addition to a closed type extrusion gun, as shown in an external view in FIG. For closing the open part of the upper half of the semi-cylindrical extrusion cylinder 81 in the extrusion gun provided with the extrusion cylinder 81, the piston 82 moving inside the extrusion cylinder 81, and the trigger mechanism 83 for moving the piston 82 Even if an extrusion gun having a structure provided with an openable / closable lid 84 is employed, the same effect can be obtained. Moreover, the system which moves the piston of each above extrusion gun with a screw may be sufficient.

  Furthermore, since the main body of the container of the present invention is a flexible pouch, when extruding the contents, the pouch is sandwiched between two rolls instead of the above-described extrusion gun. It is possible to extrude the contents by pushing out the contents or the pouch by hand, and the extrusion equipment or the extrusion method is not limited at all.

  Note that the male screw and the female screw described above may be configured in the reverse relationship. That is, a configuration in which a female screw is used instead of a male screw and a male screw is used instead of a female screw is also an aspect of the present invention.
