Description

  The present invention relates to a squeezing device for squeezing a reactive ink chemical from a flexible container.

  A liquid or high-viscosity material such as ink is stored in a suitable container after production in consideration of properties, storage capacity, storage environment, and the like. At this time, when the ink components are mixed, a polymerization reaction or the like is started immediately.If the ink cannot be stored for a long time, the two or more substances that react are put in separate containers and stored. It is necessary to ensure long-term storage stability. In this case, immediately before use, each drug in each container is mixed and stirred and then used.

  Conventionally, two or more kinds of drugs are separately put in containers made of rigid materials such as plastic or metal, stored separately, and two or more kinds of liquid or high viscosity substances are mixed and used at the time of use. However, in this method of use, the container is made of plastic or metal, but the container must be discarded after use. However, both the volume and mass of the waste after use are large, which is not preferable in terms of environmental problems.

  For this reason, as demands for reducing the burden on the global environment and waste reduction increase, deformable and flexible materials composed of flexible materials such as single-layer films made of resins, multilayer films of resins, and laminate films combining resins and metals. It is known to employ sex containers. However, in a container made of a flexible material, it takes time to take out the main agent and curing agent of the ink from each container, and it is difficult to squeeze an accurate amount from the container.

It does not squeeze the exact amount of viscous material like the main agent and curing agent of reactive ink, but a stationary squeezer for squeezing viscous material from light packaging materials is known ( Patent Document 1 and Patent Document 2).

Patent Document 4 discloses a squeezing device that squeezes mayonnaise, ketchup, toothpaste, and the like from a laminate tube. In this instrument, the two rollers are energized with an elastic body, the laminate tube is sandwiched between the two rollers, the tube is pulled while applying pressure with the elastic body, and the contents of the tube are rotated while rotating the roller. Squeeze out.
Utility Model Publication No.5-24542

  The devices described in Patent Documents 1 and 2 are stationary and large, and thus require time and effort such as movement, are expensive, and are complicated. In particular, workability is poor when a large number of drugs are continuously worked.

  In the squeezing device of Patent Document 3, a bag of retort food is held with an elliptical bar, and the contents of the bag are squeezed while the bag is wound around the bar. The present inventor has applied this squeezing device to squeezing a reactive ink. As a result, it was found that the medicine in the bag could not be squeezed out and a considerable amount was likely to remain in the bag. Since the chemical of the reactive ink has a high viscosity, the method of winding the bag around the rod-like material cannot squeeze out the viscous chemical remaining at the end of the bag. If the medicine remains in the bag in this way, the composition ratio of the ink mixture changes, and the physical properties of the coating film may not be stable. Therefore, such a squeezing device cannot be used.

  In the device described in Patent Document 4, two rollers are energized with an elastic body, a laminate tube is sandwiched between the two rollers, the tube is pulled while applying pressure with the elastic body, and the roller is rotated. Squeeze the contents of the tube. However, when trying to squeeze out a highly viscous ink chemical, the elastic body cannot apply the pressure required to squeeze out the highly viscous drug, and a large amount of the drug tends to remain in the tube. There was found. In this case, the composition ratio of the ink mixture may change, and the physical properties of the coating film may not be stable.

  In such a squeezing device, it was also considered that the elastic body urges a pressure high enough to make the tube containing the viscous ink chemicals sufficiently flat. However, when the reaction force of the elastic body is increased as described above, it is difficult to open the roller by human power. In addition, since the tube is strongly sandwiched between the rollers, it is necessary to pull the tube with one hand with a considerably large force in order to push the tube by hand and push the drug from the tube while sliding between the rollers. is there. However, if the tube is pulled with a strong force, the entire instrument is also pulled in that direction, and accordingly, the instrument must be pulled strongly so that the instrument does not move with the other hand. In this way, it is extremely difficult to move the tube quickly and stably in a state where it is strongly pulled from both sides, and if the hand slips or the position of the device or the tube shifts, the drug in the tube scatters. It sometimes adhered to the work table or to the lower ink mixing container. If this happens, the amount of the chemical charged into the ink mixing container may fluctuate and the physical properties of the coating film may become unstable. Moreover, there exists a possibility that the chemical | medical agent in a tube adhering to a mixing container inner wall surface may solidify in the state which is not mixed. The solidified extra drug falls into the mixed solution and remains as a defect in the coating film.

  An object of the present invention is a squeezing device for squeezing a reagent for reactive ink from a flexible container, which is easily operated by a human to stabilize a predetermined amount of viscous reactive ink drug. It is possible to provide a device that can be squeezed out and does not cause the drug to scatter or adhere to the mixing container wall surface.

A first rod that forms a gap for inserting the flexible container;
Forming the gap with the first rod, a second rod that is thinner than the first rod,
A gripping part for holding by hand, fixing one end of the first bar and one end of the second bar, and the other end of the first bar and the second bar A terminal fixing portion for fixing the other end of the body, wherein the first rod body and the second rod body are fixed so as not to rotate between the gripping portion and the terminal fixing portion. And

  According to the device of the present invention, a human can easily operate to stably squeeze a predetermined amount of viscous reactive ink chemicals, causing the chemicals to scatter and adhere to the ink mixing container wall. Absent. Hereinafter, the operational effects of the instrument of the present invention will be described in more detail with reference to the drawings.

  Hereinafter, as an embodiment of the present invention, the present invention will be described in more detail with an example of mixing a main component of a two-component ink and a curing agent.

  Fig.1 (a) is a front view which shows the instrument 7 which concerns on one Embodiment of this invention, FIG.1 (b) shows the Ib-Ib cross section of Fig.1 (a). On the right side in FIG. 1A, a grip 8 for gripping with one hand is provided. The grip 8 has a form and dimensions that are easy to grasp by hand. From the grip 8 toward the left, a first rod 9 that forms a gap 12 for inserting the flexible container, and a second rod 10 that forms the gap 12 together with the first rod 9. And is extended. Reference numerals 9a and 10a denote end portions of the respective rod bodies. The second rod 10 is thinner than the first rod 9. The size of the gap 12 is constant in the longitudinal direction of the rods 9 and 10.

  Further, on the left side in FIG. 1A, a terminal fixing portion 11 for fixing the other end portion 9b of the first rod body 9 and the other end portion 10b of the second rod body 10 is formed. The first rod body 9 and the second rod body 10 are fixed so as not to rotate between the gripping portion 8 and the end fixing portion 11. In this example, the portion 9c facing the gap 12 of the first rod body 9 is a curved surface, and the portion 10c facing the gap 12 of the second rod body 10 is a curved surface.

  FIG. 2 shows a rigid container 1 made of a rigid material and its lid 3. The main body 1a of the rigid container 1 has, for example, a cylindrical shape, and a stored item, for example, a main agent is introduced and stored from a circular opening 1b in the main body 1a. The flexible container 2 shown in FIG. 3 is made of a flexible material, and is a bag-shaped one that is deformed by the stored item or takes the same form as the stored item. The flexible container 2 is composed of an accommodating portion 2a whose width is expanded by injection of the contents and a narrowed mouth portion 2b.

  As shown in FIG. 4A, the rigid container 1 is opened. Next, the opening 2b of the flexible container 2 is opened. The medicine in the opened flexible container 2 is thrown toward the medicine 5 in the rigid container 1 as indicated by an arrow B. Then, as shown in FIG. 3B, the mixture is stirred as indicated by an arrow D by mechanical stirring or hand stirring. Then, the flexible container 2 is compressed as indicated by an arrow A, thinned as indicated by 2A, and discarded as indicated by an arrow C. Further, after the mixing and stirring is completed and the mixture 7 is applied to a predetermined location, the used rigid container 1 is discarded as shown by an arrow E.

  When the medicine (hardener in this example) in the opened flexible container 2 is charged toward the medicine (main agent in this example) 5 in the rigid container (mixing container) 1 as indicated by an arrow B, It is necessary that a certain amount of curing agent is charged into the rigid container 1. The squeezing device of the present invention is used to squeeze the medicine in the flexible container 2 into the rigid container 1.

  The medicine is squeezed out as shown in FIGS. That is, the holding part 8 of the instrument 7 is held with one hand 13 as shown in FIG. At this time, the rods 9 and 10 are set to face substantially in the horizontal direction. In this state, as shown in FIG. 5, the flexible container 2 is sandwiched between the rod body 10 and the rod body 9. At this time, the opening 2 c of the container 2 is positioned on the mixing container 1. Then, as shown in the side view of FIG. 7, the instrument 7 is slid downward as indicated by an arrow F while twisting the instrument 7 in the direction in which the thin rod 10 is directed downward. Then, the container 2 is sandwiched between the rods 9 and 10 and compressed to a certain narrow width, and the medicine in the container 2 is squeezed downward like 16. As a result, a predetermined amount of medicine is charged from the container 2 into the mixing container.

Here, the device of the present invention has several important improvements.
First, the ends 9 a and 10 a of the rods 9 and 10 are fixed to the grip portion 8, and the other ends 9 b and 10 b are fixed to the end fixing portion 11. Even when the medicine in the container 2 has a high viscosity, since both ends of each rod are fixed by the gripping part 8 and the terminal fixing part 11, the dimension of the gap 12 does not change to the end, and therefore the squeezing is performed. The amount will be constant.

  Further, the rod 10 is thin and the rod 9 is thick. As shown in FIG. 6, in the final stage of squeezing, the instrument 7 is further twisted so that the thin rod 10 faces downward and the thick rod 9 faces upward. Then, the remaining medicine 16 is charged into the mixing container.

As described above, when the first rod 9 is thickened and the second rod 10 is thinned, when the drug in the container 2 is squeezed to the end, the drug mainly adheres to the thin rod 10. Therefore, the amount of medicine attached to the device 7 is small, and therefore the amount of medicine not put into the mixing container can be reduced and accurately weighed. Here, it is conceivable to make both the rods 9 and 10 thin. In this case, however, the holding strength of the gap 12 is lowered and the gap 12 is easily opened.
Further, as shown in FIG. 7 in particular, the container (packaging material) 2 is slid downward in the gap 12 while twisting the instrument 7 in the direction in which the thin rod 10 is directed downward. By sliding the container 2 while twisting the instrument 7 in this manner, the width of the gap 12 becomes substantially narrower than when the instrument 7 is not twisted, and the effect of squeezing the contents 16 of the container 2 is further increased. Rise.

  It is also important that the rods 9 and 10 are fixed in a non-rotatable manner. The present inventor also examined that the rods 9 and 10 are rollers. This is because, even if the size of the gap 12 sandwiching the container 2 is reduced to reduce the residual amount at the time of squeezing, the container 2 can easily pass through the gap 12 and be handled easily.

  However, when actually making a prototype, when the rods 9 and 10 are rollers, it is difficult to adjust the force when pulling the container 2. In particular, as shown in FIG. 6, at the moment when the jig 7 is moved to the vicinity of the opening 2 c of the container 2, the roller slips and the container 2 comes off from the jig 7, and the medicine in the container 2 may be scattered. . This drug adheres to the inner wall surface of the mixing container and cures there to become a powder, which falls into the ink in the mixing container and causes coating film defects. The instrument 7 of the present invention solves such problems.

  As described above, the device 7 of the present invention can be easily handled by hand, can stably squeeze a predetermined amount of drug from the container 2, and prevent the drug from scattering from the container. It is possible to prevent contamination and coating film defects due to scattering of chemicals.

  The material of the instrument 7 is preferably a material having chemical resistance, high strength and low specific gravity. In this respect, metals such as aluminum and stainless steel are particularly preferable.

  In this example, as shown in FIG.1 (b), the parts 9c and 10c which face the gap 12 of the rods 9 and 10 are made into the curved surface. This prevents the container 2 from being damaged during squeezing and reduces the force required for squeezing.

  The size of the gap 12 is not particularly limited, and an appropriate width is determined by the thickness of the flexible container 2 and the viscosity of the medicine. For example, 1.0 mm to 3.0 mm is preferable, and 1.5 to 2.0 mm is particularly preferable. By setting the gap size G to 1.0 mm or more, it is easy to insert the flexible container 2 into the gap 12 and the workability is good. By setting G to 3.0 mm or less, the remaining amount of medicine in the container after squeezing can be reduced.

  It is necessary to determine the length of the rods 9 and 10 according to the size of the container 2 that squeezes the medicine. For example, the length of the rods 9 and 10 is preferably 20 to 40 mm larger than the width of the container 2.

  The rigid container needs to protect the medicine 5 from external forces such as impact during handling, transportation and storage, and the container itself should not be deformed by the force from the inside of the fluid. To obtain their strength, rigid containers are made rugged and have a large mass. However, the rigid container is disposed as industrial waste after the fluid is taken out or after stirring and mixing. Therefore, when a container made of a rigid material is discarded, it is bulky and becomes an environmental problem.

  The rigid container is used as a container for stirring. Since the drug in the flexible container can be put into the rigid container and stirred and mixed as it is with a stirrer, it is not necessary to prepare a separate container for stirring. Thus, by using the rigid container 1 as a stirring container for the mixture 7 immediately before use, a separate container for stirring becomes unnecessary, the work man-hour is not increased, and the burden on the operator can be reduced.

  As described above, by using a rigid container and a flexible container in combination, when two or more types of contents are stirred and mixed, there is an effect in reducing waste than when only a rigid container is used. The work man-hours and labor can be reduced as compared with the case where only the flexible container is used. Since it can contribute to resource saving and reduction of the amount of waste, and work efficiency can be reduced, it is possible to provide a method that meets the recent demand for both environmental problems and work efficiency.

  For example, in the field of mixing and stirring a plurality of kinds of contained materials in which a polymerization reaction starts immediately after mixing and curing proceeds like a two-component curable ink, a rigid container and a flexible container are used in combination. The use of rigid containers as stirring containers has been overlooked so far. However, such a method of use provides a great industrial advantage.

  Materials constituting the rigid container include metals such as iron and aluminum, and plastics such as PET (polyethylene terephthalate), FRP (fiber reinforced plastic), PP (polypropylene), and PE (polyethylene). Select one that is suitable for use. The shape of the rigid container is preferably a cylindrical shape such as a bottomed square cylindrical shape or a bottomed cylindrical shape. A bottomed rectangular tube-shaped container can reduce the space for transportation and storage. A cylindrical container with a bottom is resistant to stress from the inside and outside of the container, and is excellent in workability for the purpose of being used as a stirring container when mixing two or more kinds of contents. The rigid container preferably has a sufficiently large volume so as not to hinder the mixing of two or more kinds of contents from the viewpoint of charging and mixing the contents of the flexible container.

  Examples of the flexible material constituting the flexible container include a single layer or a multilayer film made of an ethylene-based, polyester-based, nylon-based, or polypropylene-based resin. Also, a laminate film made of a metal such as aluminum and a resin can be used. The shape of the flexible container may be either a flat bag or a self-supporting bag (also called a stand pouch or a standing pouch), and may have a pouring inlet depending on the contents. The shape of the container, the type of flexible material, the layer structure, etc. are not particularly limited. In order to take out not only the type of container, practical strength, and preservability but also the remaining amount on the inner wall of the container as much as possible. It is appropriate to select and use a suitable one.

  The width c of the flexible container 2 is the diameter d of the rigid container 1 (the width d in the case of a square container) from the viewpoint of ease of charging the drug B in the container 2 into the rigid container 1. Preferably it is smaller.

  The kind of ink and the kind of each medicine are not limited. Preferably, the main agent is accommodated in the rigid container, and the curing agent is accommodated in the flexible container.

  Moreover, the kind of reaction of each chemical | medical agent which comprises ink is not limited. For example, it may be a polymerization reaction involving an isocyanate curing agent. The ink curing method may be thermal curing, ultraviolet curing, heat and ultraviolet curing. The ink application method is not limited, and may be, for example, screen printing, curtain coating, spray coating, roll coater, or the like. Although the use of the ink is not limited, for example, it is an ink for forming a film on a semiconductor circuit board.

(Example)
According to the procedure described with reference to FIGS. 1 to 6, the main component of the two-part curable ink and the curing agent were mixed to prepare an ink. However, the rigid container 1 was made of a tin steel plate, had a bottomed cylindrical shape, and had a diameter d of 175 mm. The flexible container 2 was formed of a laminate film having a layer thickness of 125 μm made of aluminum and a polyester resin. The width c was 180 mm.

  The main agent 5 (3 kg) is stored in the rigid container 1, and immediately before use, the opening 2c of the flexible container 2 containing the curing agent 16 is opened, and the curing agent is placed in the rigid container 1 as indicated by the arrow B. I put it in. At the time of charging the curing agent, squeezing was performed using the instrument 7 of the present invention. The length of the rods 9 and 10 was 210 mm, and the size G of the gap 12 was 1.5 mm.

  Although the same test was conducted 10 times, it was possible to squeeze out the curing agent easily. The amount of residual curing agent in the container after squeezing was 0.7 to 1.1%. After squeezing out the curing agent, the mixture was stirred for 30 minutes at 60 rpm using an agitator to obtain an ink. When this ink was applied on a circuit board according to a predetermined pattern and cured, a good coating film was obtained.

(Comparative Example 1)
An ink was prepared and a coating film was formed in the same manner as in the example. However, the instrument described in Utility Model Registration No. 3073364 was used. The residual amount of the curing agent in the flexible container after squeezing was 1.7 to 7.0%. Therefore, in this example, the physical properties of the formed coating film change.

(Comparative Example 2)
An instrument having a form as shown in FIG. 1 was used, an ink was prepared in the same manner as in the example, and a coating film was formed. However, the rods 9 and 10 were rotatable. When tested 10 times, the residual amount of the curing agent in the flexible container after squeezing was 0.7 to 1.1%. However, the container was completely removed from the instrument 7 twice, and the curing agent was scattered and adhered to the edge and the periphery of the mixing container. The ink adhering to the edge of the container is cured and mixed during mixing, which adversely affects the formation of the coating film.
