Description

The present invention relates to a method of manufacturing a dispensing container and a waterproof coating.

An example of a waterproofing method for waterproofing various bases such as the rooftop and outer walls of a building is a coating film waterproofing method. This coating film waterproofing method waterproofs the base by applying a liquid waterproofing agent to form a waterproof coating that covers the base. In such a coating film waterproofing method, it is important to control the thickness of the waterproof coating because it is necessary to ensure the waterproof performance and durability of the waterproof coating over a long period of time.

In order to ensure the film thickness of the waterproof coating film, for example, Patent Document 1 discloses that a mesh sheet of a color different from that of the liquid waterproofing agent is attached to the coating film forming surface as a rising surface, and the mesh sheet is covered from above until the mesh sheet is hidden. A method of applying a liquid waterproofing agent has been proposed. According to such a method, it is possible to ensure a certain thickness or more for the waterproof coating film.

≪Discharge container≫
The discharge container of this embodiment is used to discharge a liquid waterproofing agent onto a coating film forming surface including the surface of a rising surface or the surface of a coating base material applied to a rising surface. Specifically, this discharge container is flexible and includes a storage part that stores the liquid waterproofing agent, and a container that stands up and is connected to the outside of the storage part, or a container that covers the opening of the storage part. The liquid supply cylinder is provided with a liquid supply cylinder that extends outwardly from the provided discharge cap and has an opening at its tip.

Note that the surface on which the coating film is formed may include, in addition to the surface of the rising surface or the surface of the coating base material applied to the rising surface, the floor surface in the vicinity of this rising surface. Examples of rising surfaces include waist walls of verandas and balconies, parapets, and the like.

Hereinafter, in order to more specifically describe the discharge container of the present embodiment, the discharge containers of the first to fourth embodiments will be described, but the present invention is not limited to the following specific examples.

[Discharge container of first embodiment]
The discharge container of the first embodiment will be explained using FIGS. 1 to 3. FIG. 1 is a schematic perspective view of the discharge container of the first embodiment. FIG. 2 is a schematic plan view of the discharge container of the first embodiment. FIG. 3 is a schematic cross-sectional view taken along line AA of the discharge container of the first embodiment. FIG. 4 is a schematic diagram for explaining how to use the discharge container of the first embodiment.

A discharge container 1 shown schematically in FIGS. 1 to 3 is used to discharge a liquid waterproofing agent onto a surface on which a coating film is formed, including the surface of a rising surface or the surface of a paint base material applied to a rising surface. be. Specifically, this discharge container 1 is flexible and consists of a housing part 11 for storing a liquid waterproofing agent, and an opening part 121 at the tip of the housing part 11. A liquid sending cylinder 12 is provided.

The accommodating portion 11 is a portion that accommodates a liquid waterproofing agent. This housing portion 11 is a substantially cylindrical tube, and stores a liquid waterproofing agent inside the tube. One end of the cylindrical body in the height direction is closed by providing a bottom surface. On the other hand, the other end of the cylindrical body of the accommodating portion 11 is also provided with a bottom surface, and a liquid feeding cylinder 12 is provided so as to stand up and connect to the outside from the bottom surface. An opening 121 is provided at the tip of the liquid sending tube 12 on the side opposite to the housing section 11 . Further, the liquid sending tube 12 and the housing section 11 are communicated with each other, and the liquid waterproofing agent stored inside the housing section 11 can be discharged from the opening 121 via the liquid feeding tube 12.

The accommodating portion 11 has flexibility because it is made of a flexible resin such as polyethylene resin, a composition containing such a resin, or the like. Since the accommodating portion 11 has flexibility in this manner, the amount of liquid waterproofing agent to be discharged can be adjusted by the pressure with which the construction worker grips the accommodating portion 11.

The area of the opening at the tip of the liquid sending cylinder 12 is not particularly limited, but may be 10 mm ² or more, 20 mm ² or more, 30 mm ² or more, 40 mm ² or more, 50 mm ² or more, 60 mm ² or more, 70 mm ² or more, 80 mm ² or more, It is preferably 90 mm ² or more and 100 mm ² or more.

In addition, the area of the opening in the continuous part 13 between the liquid sending cylinder 12 and the storage part 11 is not particularly limited, but may be 30 mm ² or more, 40 mm ² or more, 50 mm 2 or more, 60 mm ^{2 or} more, 70 mm ² or more, and 80 mm. ² or more, preferably 90 mm ² or more, or 100 mm ² or more.

In the discharge container 1 shown in FIGS. 1 to 3, the mechanism for introducing the liquid waterproofing agent into the storage section 11 is omitted, but the discharge container 1 has a mechanism for introducing the liquid waterproofing agent into the storage section 11. This does not exclude that.

As shown in FIG. 3, using such a dispensing container 1, when a liquid waterproofing agent is discharged onto a rising surface (particularly the upper part thereof), the liquid waterproofing agent adhering to the rising surface will flow to the bottom by gravity, but due to the viscosity Because of the high water resistance, many liquid waterproofing agents do not flow all the way to the floor surface, but remain on the rising surface with a certain thickness and smoothness. Therefore, much time is not required for smoothing application (smooth application) using a brush or a trowel. In this way, when forming a waterproof coating film on the surface of the rising surface, work efficiency can be increased by using the discharge container 1.

A method of using the discharge container 1 will be explained in more detail with reference to the drawings. FIG. 4 is a schematic diagram for explaining how to use the discharge container of the first embodiment.

A rising surface R stands vertically from the floor surface F, and a parapet P is provided below the rising surface R. When performing waterproof coating on this parapet P, the liquid waterproofing agent is released from the dispensing container 1 by tilting the liquid phase cylinder side of the dispensing container 1 containing the liquid waterproofing agent downward and pressing the housing part. It is discharged. The liquid waterproofing agent is discharged over the entire parapet P by discharging the liquid waterproofing agent while moving along the parapet P in the longitudinal direction (toward the back of the page).

[Discharge container of second embodiment]
The discharge container of the second embodiment will be described below with reference to FIGS. 5 to 7. FIG. 5 is a schematic perspective view of the discharge container of the second embodiment. FIG. 6 is a schematic plan view of the discharge container of the second embodiment. FIG. 7 is a schematic cross-sectional view taken along line BB of the discharge container of the second embodiment. Note that since the usage method is the same as that in the first embodiment, detailed explanation will be omitted here.

The discharge container 2 shown schematically in FIGS. 5 to 7 is used for discharging a liquid waterproofing agent onto a surface on which a coating film is formed, including the surface of a rising surface or the surface of a paint base material applied to a rising surface. be. Specifically, this discharge container 2 has flexibility and stands up outward from a storage section 21 that accommodates the liquid waterproofing agent and a discharge cap 22 provided so as to cover an opening 211 of the storage section 21. It is provided with a liquid sending cylinder 23 which is arranged in series and has an opening 231 at its tip.

The accommodating portion 21 is a portion that accommodates a liquid waterproofing agent. This housing portion 21 is a substantially cylindrical tube, and stores a liquid waterproofing agent inside the tube. One end of the cylindrical body in the height direction is closed by providing a bottom surface. On the other hand, the other end of the cylindrical body of the accommodating portion 21 is provided with an opening 211 that has an open bottom and rises up to surround the periphery. A male spiral portion 212 is formed on the outer peripheral surface of the opening 212 and is configured to be able to be screwed into the female spiral.

A discharge cap 22 is provided to cover such an opening 211. A female spiral portion 221 is formed on the inner circumferential surface of the discharge cap and is configured to be screwable with the male spiral portion 212 of the opening 211 . When the male spiral part 212 and the female spiral part 221 are screwed together, the accommodating part 21 and the discharge cap 22 are connected to form one discharge container 2. In other words, the housing portion 21 and the discharge cap 22 are in a separable state.

From the top 222 of the discharge cap 22, a liquid sending cylinder 23 is provided so as to stand up and connect outward. An opening 231 is provided at the tip of the liquid sending tube 23 on the side opposite to the housing section 21 . In addition, in the connected state of the storage section 21 and the discharge cap 22, the liquid sending tube 23 and the storing section 21 are communicated with each other, and the liquid waterproofing agent stored inside the storing section 21 is passed through the liquid sending tube 23. Thus, it can be discharged from the opening 231.

The accommodating portion 21 has flexibility because it is made of a flexible resin such as polyethylene resin, a composition containing such a resin, or the like.

In such a discharge container 2, like the discharge container 1, work efficiency can be improved. In addition, by providing the discharge cap 22, unscrewing the male spiral part 213 and the female spiral part 221, and removing the discharge cap 22 from the housing part 21, the liquid waterproofing agent can be easily introduced into the housing part 21. Or, conversely, the liquid waterproofing agent can be removed from the storage section 21.

≪Discharge container of third embodiment≫
The discharge container of the third embodiment will be described below with reference to FIGS. 8 to 10. FIG. 8 is a schematic perspective view of the discharge container of the third embodiment. FIG. 9 is a schematic plan view of the discharge container of the third embodiment. FIG. 10 is a schematic cross-sectional view of the discharge container of the third embodiment taken along the line CC.

The discharge container 3 shown schematically in FIGS. 8 to 10 is used for discharging a liquid waterproofing agent onto a surface on which a coating film is formed, including the surface of a rising surface or the surface of a paint base material applied to a rising surface. be. Specifically, this discharge container 3 has flexibility and stands up outward from a storage section 31 that accommodates the liquid waterproofing agent and a discharge cap 32 provided so as to cover an opening 311 of the storage section 31. It is provided with a liquid sending cylinder 33 which is arranged in series and has an opening 331 at its tip.

Here, mainly the parts different from the discharge container 2 of the second embodiment will be explained. The configurations other than those described as different here are the same as those of the discharge container 2 of the second embodiment.

A male spiral portion 332 is provided on the outer peripheral surface of the opening 331 of the liquid sending cylinder 33 . By attaching a discharge nozzle to such a liquid sending cylinder 33, the discharge amount, discharge angle, etc. can be changed. FIG. 11 is a schematic perspective view of a nozzle used in the discharge container of the third embodiment. Further, FIG. 12 is a schematic DD cross-sectional view of the nozzle used in the discharge container of the third embodiment. It is. The discharge nozzle 4 shown in FIGS. 11 and 12 has a truncated conical tube shape, and the upper and lower ends 51 and 52 (the upper and lower sides on the paper, and the positional relationship is not limited in any way) are open. . Further, in the discharge nozzle 5, a female spiral portion 53 is formed on the inner peripheral surface of the lower end portion, and the male spiral portion 332 of the liquid feeding cylinder 33 and the female spiral portion 53 of the discharge nozzle 5 are screwed together. As a result, the liquid sending cylinder 33 and the discharge nozzle 5 are connected.

The area of the opening at the tip of the discharge nozzle 5 is not particularly limited, but is 10 mm ² or more, 20 mm 2 or more, 30 mm ^{2 or more, 40 mm 2 or} more, 50 mm ^{2 or more, 60 mm 2 or more, 70 mm 2 or more} , 80 mm ² or more, 90 mm. ² or more, preferably 100 mm ² or more.

Note that the shape of the discharge nozzle is not limited to the shapes shown in FIGS. 11 and 12. FIG. 13 is a schematic perspective view of a discharge nozzle according to another embodiment. The discharge nozzle 5A has one bent portion 51A. Further, the discharge nozzle 5B has two bent portions. Note that in FIG. 13, the bent nozzle is made up of one part, but it may be made up of a plurality of parts. By having a bent nozzle, the efficiency of waterproof coating work can be increased, especially in narrow spaces such as parapets.

The nozzle is not particularly limited, but a commercially available nozzle, such as a caulking gun nozzle, may be used. By cutting the tip of the caulking gun nozzle with scissors or a cutter, you can adjust the diameter of the opening at the tip and control the discharge amount.

Further, when a commercially available product such as a caulking gun nozzle is used and the bent nozzle is constructed from a plurality of parts, a bent joint for the caulking gun may be used for the bent portion.

In one embodiment, the bending angle of the bending portion is not particularly limited, but is preferably, for example, 30° or more, 35° or more, or 40° or more. On the other hand, the bending angle of the bent portion is preferably 60° or less, 55° or less, or 50° or less. When the bent part has an angle within the above range, when discharging the liquid waterproofing agent, the opening of the storage part can be made perpendicular to the direction of gravity, and the liquid waterproofing agent can be discharged from diagonally above the surface on which the coating film is formed. Therefore, the liquid waterproofing agent can be discharged without leaving it in the storage part. On the other hand, in the case where there is no bent part, when attempting to discharge diagonally above the coating film formation surface, it is necessary to tilt the opening of the storage part with respect to the direction of gravity. In this case, when the liquid waterproofing agent is discharged, there is a portion in the storage portion that is disposed below the opening, and the liquid waterproofing agent may accumulate in this portion, and the liquid waterproofing agent may remain in the storage portion.

In this way, by providing the male spiral part 332 on the outer periphery of the liquid sending cylinder 33 and making it possible to connect the discharge nozzle 45, the discharge amount and discharge angle can be freely adjusted, improving the workability of waterproof coating. It is possible to increase the height and perform flexible construction.

≪Discharge container of fourth embodiment≫
The liquid sending cylinder is not limited to one that is not bent like the discharge container of the third embodiment, and the liquid sending cylinder may be bent.

Hereinafter, the discharge container of the fourth embodiment will be described using FIG. 14. FIG. 14 is a schematic perspective view of the discharge container of the fourth embodiment.

The discharge container 4 shown schematically in FIG. 14 is used to discharge a liquid waterproofing agent onto a coating film formation surface including the surface of a rising surface or the surface of a coating base material applied to a rising surface. Specifically, the discharge container 4 has a flexible housing section 41 that accommodates the liquid waterproofing agent, and a discharge cap 42 that is provided to cover an opening (not shown) of the housing section 41. It is provided with a liquid sending cylinder 43 which is arranged in a standing manner outwardly and has an opening 431 at its tip.

Here, mainly the parts different from the discharge container 3 of the third embodiment will be explained. The configurations other than those described as different here are the same as those of the discharge container 3 of the third embodiment. In such a discharge container 4, the liquid feeding tube 43 is bent at an angle in the height direction of the discharge container 4, and has a bent portion 433. A male spiral portion 432 is provided on the outer peripheral surface of the opening 431 of the liquid feed etc. 43. The liquid feed etc. 43 can be connected to the discharge nozzle 5 through this male spiral portion 432 in the same manner as the discharge container of the third embodiment. Thereby, the discharge nozzle 5 forms an angle in the height direction of the discharge container 4. By forming the discharge nozzle 5 at an angle in the height direction of the discharge container 4 in this way, it can be used particularly in narrow spaces such as parapets, similarly to the case where the discharge nozzles 5A and 5B are used in the discharge container 3 of the third embodiment. It can improve the efficiency of waterproof coating work.

Note that when the discharge nozzle has a bent portion, the bending angle of the bent portion is not particularly limited, but is preferably, for example, 30° or more, 35° or more, or 40° or more. On the other hand, the bending angle of the bent portion is preferably 60° or less, 55° or less, or 50° or less. When the bent part has an angle within the above range, when discharging the liquid waterproofing agent, the opening of the storage part can be made perpendicular to the direction of gravity, and the liquid waterproofing agent can be discharged from diagonally above the surface on which the coating film is formed. Therefore, the liquid waterproofing agent can be discharged without leaving it in the storage part. On the other hand, in the case where there is no bent part, when attempting to discharge diagonally above the coating film formation surface, it is necessary to tilt the opening of the storage part with respect to the direction of gravity. In this case, when the liquid waterproofing agent is discharged, there is a portion in the storage portion that is disposed below the opening, and the liquid waterproofing agent may accumulate in this portion, and the liquid waterproofing agent may remain in the storage portion.
