Description

  The present invention relates to an adhesive case capable of breaking a bag filled with an adhesive by a simple operation and taking it out from the outlet, and in particular, by attaching a nozzle to the outlet, The present invention relates to an adhesive case that can break the wrapping bag with an edge member housed in an inner bottom portion and take out the adhesive.

  Conventionally, a wide variety of organic materials and inorganic materials have been used as adhesives. For example, as shown in Japanese Patent Laid-Open No. 6-321258 (Patent Document 1), the amount of waste after use and the environment are reduced. In consideration of this, a wrappable film made of a composite film, a foldable tube made of a laminate film containing metal, and the like are used.

  With regard to a one-component adhesive, such a storage-type adhesive having flexibility is sometimes used by being loaded in a special case and discharged by a dispenser such as a caulking gun. Yes. When discharging the adhesive, it is only possible to pierce or cut one end of the envelope-filled film filled with adhesive with a sharp object such as a cutter knife, wire, thread, or cut. Adhesive can be discharged.

  In addition, recently, an adhesive case has been put into practical use in which one end of a nozzle is projected into a sharp cylindrical shape and the breakage of the wrapping bag is completed only by attaching the nozzle without making the hands dirty.

  Also for two-component adhesives, the main agent and curing agent are stored in a predetermined volume ratio, and when used, the main agent and curing agent are discharged and mixed in a bag-like film or case for exclusive use with two-component adhesives Nozzles such as a static mixer attached to a dispenser and a discharge port have already been put into practical use. In particular, for applications related to construction and civil engineering, it has been attracting attention because it can reduce adverse effects due to adhesion and contact with the human body without mixing and stirring the conventional two-component adhesive in advance.

  This two-pack adhesive bag or case is stored and transported in a state where the main agent and the curing agent are separated. When the adhesive is used, the plunger of the dispenser pushes the piston loaded in the case to extrude the two liquids to the discharge port independently and separately, and mixes them uniformly with a static mixer. Get up. As for the two-component adhesive, when discharging the main agent and the curing agent, use a sharp knife such as a cutter knife, wire, a thousand pieces, or a sharp edge on one end of the envelope-filled film filled with the adhesive. The work of piercing or cutting is performed.

  Further, in recent years, the protrusion provided at the bottom of the discharge port is wrapped by utilizing the action that the wrapping-like film filled with the adhesive is swelled when the piston is pushed by the dispenser. Cases that break through bags and enable discharge have also been put to practical use, and are attracting attention as having good workability and low risk of contact.

  Further, for example, as shown in Japanese Utility Model Laid-Open No. 10-94 (Patent Document 2), a bottom portion of two cylindrical containers capable of separately storing two different types of adhesives is provided with a cut portion that can be removed by pressure, By providing an ejector that can be cut by pressing the cut portion on the inner surface of the discharge nozzle that can be attached to the bottom of these two cylinders, and cutting the cut portion into two pieces by attaching the discharge nozzle to the cylinder. There is also known a technique in which the adhesive in the cylinder can be taken out by a discharge nozzle.

JP-A-6-321258 10-94

  However, when using a sharp object such as a wire or a cutter knife as a method to break through a bag-like film filled with the adhesive as described above and enable the adhesive to be discharged, the number of work steps increases. Besides, there was a risk of getting dirty or injured when breaking through.

  In addition, the method of projecting one end of the nozzle into a sharp cylindrical shape and completing the breaking of the wrapping bag only by attaching the nozzle cannot pierce the wrapping bag beyond the cross-sectional area of the discharge port. When the wrapping piece enters the direction of the discharge port, the discharge resistance of the adhesive increases, and there is a problem that the discharge performance, that is, the workability is deteriorated.

  Furthermore, the method of breaking through the film-like bag by the protrusion on the bottom of the discharge outlet depends on the principle of breaking the bag by the force from the piston, so it cannot be broken through reliably. Depending on the shape and material of the product, the bag cannot be torn at the discharge site, and the bag may be ruptured at other than the predetermined site, contaminating the inside of the adhesive case, or Even if it breaks through, the cross-sectional area of the broken part does not exceed the cross-sectional area of the discharge port, and as a result, there is a problem that the discharge resistance increases and the operation becomes difficult.

  Therefore, as an adhesive case to be used with an adhesive filled in a sachet-shaped film, the sachet is surely pierced without extra work such as piercing with a blade, and contact with the human body There has been a strong demand for the appearance of an adhesive case that has no risk of injury or the like, has an opening area of a broken sachet that is larger than the cross-sectional area of the discharge port, has low discharge resistance, and has good workability.

  Further, the technique described in the above-mentioned Patent Document 2 is effective when the adhesive is accommodated in the cylindrical container, but the composite film such as a plastic material or the aluminum as shown in the above-mentioned Patent Document 1 is used. In the case of an adhesive housed in a sachet manufactured using a laminate film containing a metal such as foil, this technique has a problem that it cannot be used.

  The adhesive case according to the present invention is a completely newly developed technique in view of the above-mentioned many problems of the prior art, and in particular, an adhesive used by loading an adhesive filled in a bag-like film. In the case for the agent, the piercing operation of the bag-like film at the discharge port is completed easily and reliably by only one operation of attaching the nozzle, and there is no risk of contact or injury, and the pierced package The opening of the bag is larger than the cross-sectional area of the discharge port, and a substantial area of the opening is maintained, and an object of the present invention is to provide an adhesive case with good workability when discharging adhesive. .

  In order to achieve the above object, the adhesive case of the first invention according to the present invention is a hollow case that can accommodate a wrapping bag that is provided with an outlet at which an nozzle can be attached and is filled with an adhesive. In a case for an adhesive comprising a cylinder, a blade-like component capable of breaking through the sachet is housed in an inner bottom portion of the discharge port, and a push rod provided continuously with one end of the blade-like component This is a case for an adhesive, characterized in that its tip is exposed at the opening of the discharge port.

  A second invention of the adhesive case is the adhesive case of the first invention, characterized in that an outer area of the blade-shaped part is formed larger than a cross-sectional area of the discharge port.

  According to a third aspect of the adhesive case, when the nozzle is attached to the discharge port of the cylinder, the nozzle pushes down the push rod exposed at the upper end opening of the discharge port to move the blade-like component. It is the case for adhesives of the 1st invention or the 2nd invention characterized by breaking the packing bag.

  According to a fourth aspect of the adhesive case, the first to third aspects of the invention are characterized in that the blade-like part is prevented from being pushed into the discharge port by pressing a broken piece of the package. This is an adhesive case.

  Since the adhesive case of the first invention according to the present invention has the above-described configuration and operation, the packaging bag filled with the adhesive is accommodated in the adhesive case made of a cylinder and is provided on the cylinder. By attaching the nozzle to the discharge port, the wrapping bag is broken by a push rod provided in the discharge port that is moved by being pushed by the nozzle, and a blade-like component that is connected to the push rod. Can be taken out from the nozzle. Therefore, the operation of taking out the adhesive is extremely simple, and the adhesive case can be used repeatedly, which is economical.

  In the adhesive case of the second invention according to the present invention, since the outer area of the blade-shaped part is larger than the cross-sectional area of the discharge port, the wrapping bag is widely broken, and the broken piece of the wrapping bag has the discharge port. It is possible to take out all the adhesive in the sachet while preventing the closure.

  The adhesive case of the third invention according to the present invention has a nozzle mounted on the discharge port of the cylinder, and pushes the push rod of the discharge port to move the blade-shaped part to break the wrapping bag. The adhesive can be taken out.

  The adhesive case according to the fourth aspect of the present invention can prevent the broken piece from entering the discharge port and closing the discharge port by pressing the broken piece as it is with the blade-shaped part obtained by breaking the bag.

  An embodiment of an adhesive case according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional explanatory view of the main part of the adhesive case according to the present invention, and FIG. 2 is a cross-sectional explanatory view of the main part in a state in which the adhesive housed in the adhesive case is taken out.

  In FIGS. 1 and 2, reference numeral 1 denotes an adhesive case, which is formed of a hollow cylinder, and a discharge port 2 is erected on its upper portion. A spiral screw 3 is provided on the outer periphery of the discharge port 2. The lower part (bottom part) of the adhesive case 1 made of this hollow cylinder is opened, and the wrapping bag 4 filled with the adhesive 13 can be freely taken in and out from the lower part. The opening portion of the sachet 4 is closed by a ring to form a clip portion 5.

  A piston (not shown) attached to a plunger is inserted in the lower part (bottom) of the adhesive case 1 so that the piston can be reciprocated in the cylinder by pushing and pulling the plunger. It is configured.

  As shown in the figure, the discharge port 2 communicates with the ceiling portion of the adhesive case 1, and the inner bottom of the discharge port 2 has a wide storage for storing a blade-like component 6 described later. A recess 7 is provided. Further, a ceiling recess 7 b in which the clip portion 5 of the wrapping bag 4 can be stored is provided in the center of the ceiling portion of the adhesive case 1.

  A blade-like component 6 is housed in a substantially horizontal direction in the housing recess 7 at the inner bottom of the discharge port 2. A cutting blade 6 a having a tip formed at an acute angle protrudes from the lower surface of the base portion of the blade-like component 6. A push bar 8 is continuously provided on the upper surface of the base part of the blade-like component 6. A V-shaped cut 9 for smoothing the movement of the blade-like component 6 is provided at the connecting portion between the two.

  An insertion recess 7 a into which the tip of the blade-like component 6 can be inserted is provided in a part of the storage recess 7. A push rod 8 connected to the base of the blade-like component 6 is inserted into the discharge port 2, and the upper end of the push rod 8 is exposed from the upper end of the discharge port 2 with a predetermined length.

  Reference numeral 10 denotes a nozzle that can be attached to the discharge port 2, and a screw 11 that can be screwed with the screw 3 of the discharge port 2 is provided on the inner bottom portion thereof. The passage of the nozzle 10 is formed with a smaller diameter than the passage of the discharge port 2. Therefore, a wide horizontal step 12 is formed at the inner bottom where the screw 11 is provided and the lower end of the passage.

  Next, when the adhesive stored in the packaging bag 4 is taken out from the adhesive case 1, the packaging bag 4 is stored in the adhesive case 1, as shown in FIG. When the nozzle 10 is screwed into the discharge port 2 using 11, the horizontal step 12 of the nozzle 10 is brought into contact with the upper end of the push rod 8 to push down the push rod 8. The base part of the blade-like component 6 provided continuously is lowered, the back of the bag 4 is broadly cut by the cutting blade 6a of the blade-like component 6, and the adhesive 13 in the bag 4 is allowed to flow out for bonding. The agent 13 can be poured out from the tip of the nozzle 10 through the discharge port 2.

  As described above, since the V-shaped cut 9 is provided in the connecting portion of the blade-like component 6 and the push rod 8, when the push rod 8 is pressed by the nozzle 10, the base portion of the blade-like component 6 is The wrapping bag 4 can be broadly broken by turning smoothly smoothly with the tip portion inserted in the insertion recess 7a as a fulcrum.

  And since the push rod 8 is always pressed by the nozzle 10, the blade-like component 6 is fixed as it is, and thereby the broken piece 4a of the sachet 4 is pressed by the blade-like component 6, and the broken piece 4a is fixed. It is possible to prevent the discharge port 2 from being closed by entering the passage of the discharge port 2.

  Further, by moving a piston (not shown) inserted into the bottom of the adhesive case 1 with a plunger, the adhesive filled in the sachet 4 in the adhesive case 1 is gradually poured out from the nozzle 10. Can be taken out efficiently. After all the adhesive of the packaging bag 4 accommodated in the adhesive case 1 is taken out, the adhesive 13 can be similarly removed by replacing the new packaging bag 4 in the adhesive case 1. .

  The adhesive case 1 according to the present invention substantially follows the shape of the wrapping bag 4 through a push bar 8 provided along the discharge port 2 in association with the mounting operation of the nozzle 10. Since the blade part 6 is characterized by breaking through the film of the wrapping bag 4 larger than the cross-sectional area of the discharge port 2, the size of the blade-like part 6 having various shapes is an effective area for breaking the wrapping bag 4. It is preferable to design so that is larger than the cross-sectional area of the discharge port 2.

  When the effective area of the opening diameter that breaks the sachet 4 is equal to or smaller than the cross-sectional area of the discharge port 2, the discharge resistance of the adhesive 13 increases, resulting in a decrease in workability. When the effective area is equal to or larger than the cross-sectional area of the discharge port 2, the discharge resistance is the lowest. However, when the effective area is too large, the blade-like component 6 for breaking through the sachet 4 is also large and cannot be accommodated in the adhesive case 1. . Preferably, the cross-sectional area of the discharge port 2 is 1.1 to 4 times, and 1.5 to 2.5 times is an optimal design value.

  It is important that the shape of the blade-like component 6 in the present invention is designed so as to substantially follow the shape of the wrapping bag 4. For example, when the end portion of the wrapping bag 4 is sausage-shaped, the blade-like component 6 is It is preferable to form as a plate-like component having a rounded portion in the surface direction, that is, a substantially spherical curved surface. Thus, the blade-shaped part 6 can form molded parts of various shapes depending on the shape of the bag 4. A sharp blade-shaped part can be formed on a part or the entire periphery of the blade-shaped component 6, and a substantially triangular or polygonal shape in which the tip is easy to be sharp is preferable.

  Various kinds of materials can be used for the blade-like component 6, and examples thereof include metals, plastics, fiber-reinforced plastics, ceramics, etc., but in consideration of economy, reinforced plastics are preferable, and injection molding containing carbon fibers is possible. Plastic is the best. The blade-like component 6 in the present invention must be between the packaging bag 4 filled with the adhesive 13 and the bottom surface of the discharge port 2, and can be attached to the discharge port 2 or a bag-shaped film. I do not care.

  Further, the blade-like component 6 in the present invention may have a structure in which the entire component is pushed into the wrapping bag 4, but may have a structure in which one end is fixed as a fulcrum and the other end is pushed into the wrapping bag 4. However, in order to increase the stroke when the component is pushed in, a structure in which one end is fixed and the portion close to the fulcrum is pushed by the push rod 8 by using the lever principle is preferable. Further, the blade-like component 6 in the present invention also serves as a lid that prevents the broken piece 4a of the film that has been broken once from entering the discharge port 2.

  The push bar 8 having an action of pushing the blade-like component 6 in conjunction with the mounting operation of the nozzle 10 according to the present invention is essential to be arranged along the discharge port 2, but is disposed anywhere in the discharge port 2. It does not matter. However, in order to push the blade-like component 6 into the wrapping bag 4 and increase the stroke to be pierced as described above, it is preferable to place the blade-like component 6 at the discharge port 2 so as to push the portion close to the fulcrum of the molded component.

  Further, the push rod 8 and the blade-like component 6 may be integrated, and in this case, in order to make the operation smooth, a cut or the like is provided in the connecting portion between the push rod 8 and the molded component 6. It is also possible. The shape of the push rod 8 in the present invention is not particularly limited, but is preferably a substantially cylindrical shape, a plate-like prismatic shape, or a circular arc shape. In the case of a cylinder, the diameter is preferably 1 to 5 mm, more preferably 2 to 3 mm. In the case of a plate shape, a thickness of 1 to 3 mm and a width of 2 to 5 mm are suitable.

  In an arc column shape, it is preferable to design along the curved surface of the discharge port 2. The length of the push rod 8 is not limited at all as long as the nozzle 10 and the blade-like component 6 of the present invention are interlocked with each other via the push rod 8.

  However, when the nozzle 10 is attached, the blade-like component 6 according to the present invention can function as a so-called support rod that breaks through the wrapping bag 4 filled with the adhesive 13 and maintains the distance from the nozzle 10. It is important to adjust the length. Various kinds of materials can be used for the push rod 8, and examples thereof include metals, plastics, fiber reinforced plastics, ceramics, and the like. In view of economy, reinforced plastics are preferable, and injection molding containing carbon fibers is possible. Plastic is the best.

  Any material can be used as the material of the film forming the sachet 4 in the present invention. Low density polyethylene, medium density polyethylene, high density polyethylene, unstretched polypropylene, biaxially stretched polypropylene, polyvinylidene chloride, polychlorinated Vinylidene coated biaxially stretched polypropylene, stretched nylon 6, unstretched nylon 6, polyvinylidene chloride coated nylon 6, stretched nylon 66, unstretched nylon 66, polyvinylidene chloride coated nylon 66, polyethylene terephthalate, polyvinylidene chloride coated polyethylene terephthalate, etc. These can be used as single or multiple laminate films.

  When used alone, a seamless tube by extrusion molding or a tube in which a film is enveloped by a heat sealer or the like, or a palm is stretched can be used. Examples of the laminating method include dry laminating using an adhesive and ectrusion laminating which is melted and coextruded. In addition, an aluminum sheet layer, an aluminum vapor deposition layer, or a silica vapor deposition layer can be used for the purpose of gas barrier or light shielding.

  Although there is no restriction | limiting in particular as the thickness of the film which comprises the sachet 4, If too thick, it will become difficult to pierce a film with the blade-shaped component 6 in this invention, and if too thin, it will be wrapped at the time of storage and transportation The film may burst. The substantial thickness is preferably in the range of 10 to 300 μm, preferably 50 to 200 μm, more preferably 80 to 120 μm.

  Further, the adhesive case 1 in the present invention can be used not only as a one-component type but also as a two-component type adhesive case. The cylinder of the adhesive case 1 may be substantially hollow and can be designed freely. However, in view of the structure of a widely used dispenser, a substantially cylindrical one is preferable. . A piston can be loaded into the cylinder part. In this case, in order to reduce frictional resistance and prevent biting of the envelope-like film, a plurality of linear grooves are provided in the longitudinal direction on the inner wall of the cylinder. It is also possible to treat the surface and emboss it.

  The discharge port 2 needs to be provided at one end of the cylinder, and may be integrated with the cylinder, but preferably has a structure that can be divided from the cylinder. At this time, for the purpose of preventing the backflow of the adhesive 13 to the cylinder, it is more preferable that the discharge port 2 and the bag 4 filled with the adhesive 13 are in close contact with an appropriate sealant. As the material for the adhesive case 1 in the present invention, various types can be used, and examples thereof include paper, metal, plastic, fiber-reinforced plastic, ceramic, etc. In consideration of economy, plastic and paper are preferable. Injection molded plastic is the best.

  The nozzle 10 attached to the discharge port 2 of the adhesive case 1 in the present invention is not restricted at all, and a commercially available one or one having a general shape can be used. In the case of a two-component adhesive case, a commercially available static mixer or the like can be used. In any case, it is important to use one that does not leak from the fitting portion. Further, a flat shoulder such as the horizontal step 12 as described above is provided on a part of the inner wall of the nozzle 10 so that one end of the push rod 8 in the present invention is interlocked with the mounting operation of the nozzle 10, or Selecting a nozzle having such a shape is an important factor.

  As described above, as shown in the embodiment, the adhesive case 1 is formed of a film in which the blade-like component 6 acting in conjunction with the operation of attaching the nozzle 10 pierces the film beyond the cross-sectional area of the discharge port 2 and is torn. The broken piece 4a is prevented from entering the discharge port 2, and the push rod 8 serves as a support rod to maintain the area of the opening, thereby reducing the discharge resistance and maintaining it, thus significantly improving the workability. The agent case 1 can be configured.
