Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the paint container described in Patent Document 1, since the entire surface of the paint inside the container is always in contact with the air circulating through the plurality of small holes in the inner lid, it is impossible to prevent the paint inside the container from drying.

[0005] In addition, for the paint container, in order to always allow the spring to expand and contract in the vertical direction, it is necessary to fix the lower end of the spring to the bottom of the paint container and fix the upper end of the spring to the lower surface of the inner lid. It is difficult to create a container with such a structure.

[0006] The present invention has been made in view of the above circumstances, and aims to provide a lid for a paint container that prevents the paint inside the paint container from drying out, while allowing the necessary amount of paint to be easily dispensed, and which has a simple shape. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a lid for a paint container, which is open at the top and stores paint inside, comprising: a lid body portion whose outer circumference is smaller than the inner circumference of the paint container; an outer lid portion which is pressed against the inner surface of the paint container from the inside of the paint container over its entire circumference; and the lower surface of the lid body portion of It bends upward from the outer edge and extends to the outer circumference of the lid. and is connected to the outer circumference of the lid The lid comprises a lid stand upper part, the lid body is provided with a nozzle that protrudes upward and has a nozzle that penetrates the lid body vertically, and the outer circumference of the lid is pressed against the inner surface of the paint container at a position higher than the upper end of the nozzle, and is capable of descending to the bottom of the inside of the paint container.

[0008] Furthermore, the upper part of the lid stand is characterized by being formed in a stepped manner, either entirely or partially.

[0009] Furthermore, the device is characterized by having a long handle attached to the ejection section.

[0010] Furthermore, it is characterized by being equipped with a long-term storage lid that covers the ejection hole from above and seals the ejection hole.

[0011] Furthermore, the inner circumferential surface of the long-term storage lid and the outer circumferential surface of the ejection part are provided with female and male threads, respectively, and the long-term storage lid is characterized in that it can be screwed onto the ejection part. [Effects of the Invention]

[0012] According to the paint container lid of the present invention, when the outer circumference of the lid is pressed against the inner surface of the paint container and the lid is pushed downward, the paint inside the paint container is pushed downward by the lid body, and the paint that has nowhere to go overflows from the spray hole of the spraying part onto the upper part of the lid body, and the paint accumulates between the spraying part above the lid body and the upper part of the lid stand. When the paint container lid is pushed down and the lower surface of the lid body is in contact with the paint, a sealed space of air is formed between the upper part of the lid stand and the inner surface of the paint container. Therefore, when the downward pushing of the paint container lid is stopped, the buoyancy of the space between the upper part of the lid stand and the inner surface of the paint container causes the lid body to float slightly upward, and the surface of the paint inside the spray hole moves downward. In other words, by stopping the downward pushing of the paint container lid, the paint does not overflow from the spray hole of the spraying part onto the upper part of the lid body, and the paint does not spill from the spray hole even if the paint container is tilted slightly. Therefore, the required amount of paint can be easily dispensed between the spray nozzle at the top of the lid body and the top of the lid stand.

[0013] Furthermore, when the lid of the paint container is pressed down and the underside of the lid body is in contact with the paint, the paint inside the paint container comes into contact with the air through the space between the top of the lid stand and the inner surface of the paint container, and through the spray holes. As mentioned above, the air in the space between the top of the lid stand and the inner surface of the paint container is sealed and does not circulate, so the paint dries only through contact with circulating air from the spray holes, which significantly prevents the paint from drying out.

[0014] Furthermore, by forming a stepped structure on the entire or partial top of the lid stand, it becomes possible to remove excess paint from the application tool, such as a brush or roller, by dipping it into the paint accumulated between the spray nozzle on the top of the lid body and the top of the lid stand, and then rubbing the tool against the stepped structure on the top of the lid stand.

[0015] Furthermore, the worker can grasp the long handle and move the lid body up and down or the lid for the paint container up and down without getting their hands dirty with paint.

[0016] Furthermore, by covering the ejection hole with the lid for long-term storage, the paint accumulated below the lid main body can be stored for a long time.

[0017] Furthermore, by screwing the lid for long-term storage onto the ejection part to cover the ejection hole, the paint accumulated below the lid main body can be more tightly sealed, and the lid for the ejection hole will not loosen even due to impacts such as tipping over.

Modes for Carrying Out the Invention

[0019] The first to third embodiments of the paint container lid according to the present invention will be described below with reference to the drawings. However, the following is merely an illustrative example of one embodiment of the present invention, and the scope of the present invention is not limited to the following first to third embodiments, and can be modified as appropriate without departing from the spirit of the present invention.

[0020] First, the lid 100a for the paint container of the first embodiment will be described. The paint container 8 on which the lid 100a is used is a circular bucket-shaped container that opens upwards and holds paint 9 inside 83, as shown in Figure 1. Because it opens upwards, it has a rim 82 around the entire circumference of its upper end. The rim 82 of the opening 81 of the paint container 8 is bent inwards toward the outside of the paint container 8 so that its cross-section is circular.

[0021] As shown in Figure 1, the paint container lid 100a is a polyethylene lid that is attached and fixed to the paint container 8 from above, and comprises a lid body portion 1a, a lid outer circumference portion 2a, and an expandable portion 3.

[0022] As shown in Figure 1, the lid body 1a has a planar shape with an outer circumference smaller than the inner circumference of the interior 83 of the paint container 8, and is formed so that it can be lowered from the top of the paint container 8 to the bottom 85 of the interior 83 of the paint container 8. A spraying part 11a is provided in the center of the lid body 1a, which has a spraying hole 12a that protrudes upward and penetrates the lid body 1a vertically.

[0023] As shown in Figure 1, the outer circumference 2a of the lid is shaped to enclose and fit around the edge 82 of the opening 81 of the paint container 8 from the outside. By pressing it against the edge 82 of the paint container 8 from above and fitting it onto the edge 82 around its entire circumference, the lid 100a for the paint container can be fixed to the paint container 8.

[0024] As shown in Figure 1, the expandable portion 3 extends from the outer peripheral edge 13a of the lid body portion 1a to the outer peripheral portion 2a of the lid, and its entirety is formed in a bellows-like shape. Because the expandable portion 3 is formed in a bellows-like shape, it is expandable and flexible, and because it is made of polyethylene, it is also pliable.

[0025] Then, as shown in Figure 1, the lid 100a for the paint container is attached and fixed to the paint container 8. When the lid body 1a is pushed downward toward the bottom 85 of the paint container 8, the telescopic part 3 extends downward, as shown in Figure 2, and the lid body 1a moves downward toward the bottom of the paint container 8. At this time, the paint 9 inside the paint container 8 8 83, which has been pushed downward by the lid body 1a, has nowhere to go and overflows above the lid body 1a through the ejection hole 12a of the ejection part 11a, accumulating in the space 71 between the ejection part 11a and the telescopic part 3 above the lid body 1a.

[0026] As shown in Figure 2, when the lid body 1a is pressed down and its lower surface 14a touches the paint 9, a sealed air space 72 is formed between the expandable part 3 and the inner surface 84 of the paint container 8. Therefore, by stopping the downward pressure on the lid body 1a, the buoyancy of the space 72 between the expandable part 3 and the inner surface 84 of the paint container 8 causes the lid body 1a to float slightly upward, and the surface 91 of the paint 9 filling the spray hole 12a moves downward. Thus, even if the paint container 8 is tilted slightly, the paint 9 will not spill from the spray hole 12a.

[0027] Furthermore, as shown in Figure 2, when the lid body 1a is pressed down and the lower surface 14a of the lid body 1a is in contact with the paint 9, the paint 9 inside the paint container 83 comes into contact with the air in the space 72 between the expandable part 3 and the inner surface 84 of the paint container 8, and inside the spray hole 12a. At this time, as mentioned above, the space 72 between the expandable part 3 and the inner surface 84 of the paint container 8 is sealed, so the paint 9 does not dry from the surface 92 of the paint 9 facing this space 72, and the paint 9 dries only from the surface 91 of the paint 9 formed inside the spray hole 12a, thus significantly preventing the paint 9 from drying out.

[0028] Then, an application tool for painting, such as a brush or roller (not shown), is dipped into the paint 9 accumulated between the spray nozzle 11a above the lid body 1a and the telescopic part 3 71. By rubbing the application tool against the bellows of the telescopic part 3, excess paint 9 is removed from the application tool, and the paint 9 can be applied to an object (not shown) using the application tool.

[0029] As shown in Figure 3, the telescopic part 3 can extend and retract until the lid body 1a touches the bottom 85 of the inside 83 of the paint container 8. When the paint 9 in the space 71 between the spray nozzle 11a above the lid body 1a and the telescopic part 3 is depleted while the lid body 1a is touching the bottom 85 of the inside 83 of the paint container 8, the paint container lid 100a can be removed from the paint container 8 to use up all of the paint 9.

[0030] Next, the paint container lid 100b of the second embodiment will be described. The paint container 8 on which the paint container lid 100b is used is the same as the paint container 8 described in the first embodiment, so its description will be omitted.

[0031] As shown in Figure 4, the paint container lid 100b is a polyethylene lid that is attached and fixed to the paint container 8 from above, and comprises a lid body portion 1b, a lid outer circumference portion 2b, and a lid stand upper portion 4.

[0032] As shown in Figure 4, the lid body 1b has a planar shape with an outer circumference smaller than the inner circumference of the interior 83 of the paint container 8, and is formed so that it can be lowered from the top of the paint container 8 to the bottom 85 of the interior 83 of the paint container 8. A spraying section 11b is provided in the center of the lid body 1b, which has a spraying hole 12b that protrudes upward and penetrates the lid body 1b vertically.

[0033] As shown in Figure 4, the outer circumference 2b of the lid is formed in a C-shape that opens downwards and is made of polyethylene, thus being flexible. The outer circumference of the outer circumference 2b of the lid is formed to be larger than the inner circumference 83 of the paint container 8, so that the outer surface of the outer edge 21b of the outer circumference 2b of the lid is pressed against the inner surface 84 of the paint container 8 over its entire circumference. By pressing the outer circumference 2b of the lid against the inner surface 84 of the paint container 8, the lid 100b for the paint container can be attached to the paint container 8.

[0034] As shown in Figure 4, the upper part of the lid stand 4 is a portion that extends from the outer peripheral end 13b of the lid body 1b, bends upward higher than the upper end 15b of the ejection part 11b, and extends to the outer peripheral part 2b of the lid, and has a stepped portion 41 formed in a stepped manner.

[0035] Then, as shown in Figure 4, the paint container lid 100b is attached to the paint container 8, and when the paint container lid 100b is pushed downward toward the bottom 85 of the paint container 8, the entire paint container lid 100b moves downward as shown in Figure 5. At this time, the paint 9 inside the paint container 8 8 83, which has been pushed downward by the lid body 1b, has nowhere to go and overflows above the lid body 1b through the ejection hole 12b of the ejection part 11b, and accumulates in the space 73 between the ejection part 11b above the lid body 1b and the upper part 4 of the lid stand.

[0036] As shown in Figure 5, when the paint container lid 100b is pushed down and the lower surface 14b of the lid body 1b touches the paint 9, a sealed space 74 is formed between the upper part of the lid stand 4 and the inner surface 84 of the paint container 8. Therefore, by stopping the downward pressure on the paint container lid 100b, the buoyancy of the space 74 between the upper part of the lid stand 4 and the inner surface 84 of the paint container 8 causes the paint container lid 100b to float slightly upward, and the surface 93 of the paint 9 filling the spray hole 12b moves downward. Thus, even if the paint container 8 is tilted slightly, the paint 9 will not spill from the spray hole 12b.

[0037] Furthermore, as shown in Figure 5, when the lid 100b for the paint container is pushed down and the lower surface 14b of the lid body 1b is in contact with the paint 9, the paint 9 inside the paint container 8 83 comes into contact with the air in the space 74 between the upper part of the lid stand 4 and the inner surface 84 of the paint container 8, and inside the spray hole 12b. At this time, as mentioned above, the space 74 between the upper part of the lid stand 4 and the inner surface 84 of the paint container 8 is sealed and does not circulate, so the paint 9 does not dry from the surface 94 of the paint 9 facing this space 74, and the paint 9 dries only from the surface 93 of the paint 9 formed inside the spray hole 12b, thus significantly preventing the paint 9 from drying out.

[0038] Then, an application tool for applying paint 9, such as a brush or roller (not shown), is dipped into the paint 9 accumulated between the spray nozzle 11b above the lid body 1b and the upper part of the lid stand 4 73. By rubbing the application tool against the stepped section 41 of the upper part of the lid stand 4, excess paint 9 is removed from the application tool, and the paint 9 can be applied to an object (not shown) using the application tool.

[0039] Furthermore, as shown in Figure 6, if the paint 9 in the space between the spray nozzle 11b above the lid body 1b and the upper part of the lid stand 4 runs out while the lid body 1b is in contact with the bottom 85 of the inside 83 of the paint container 8, the paint 9 can be used without waste by removing the paint container lid 100b from the paint container 8.

[0040] Next, the paint container lid 100c of the third embodiment will be described. The paint container 8 on which the paint container lid 100c is used is the same as the paint container 8 described in the first embodiment, so its description will be omitted. In addition, the paint container lid 100c has new elements added to the paint container lid 100b described in the second embodiment, so the description of the parts that are the same as the paint container lid 100b will be omitted.

[0041] The paint container lid 100c further comprises a handle 5 and a long-term storage lid 6. As shown in Figures 7 and 8, the handle 5 is a long, rod-shaped member bent into a roughly C-shape, with both ends fixed to the spray nozzle 11b so as to be rotatable. The handle 5 allows the operator to push down the paint container lid 100c without getting their hands dirty with paint 9 by grasping the handle 5 and pushing it downwards, and conversely, by grasping the handle 5 and pulling it upwards, the operator can pull up the paint container lid 100c without getting their hands dirty with paint 9.

[0042] Furthermore, as shown in Figure 8, the handle 5 is formed to be elongated so that when it is rotated and laid flat, it contacts the outer circumference 2b of the lid 100c for the paint container, thereby preventing paint 9 from adhering to the gripping portion of the handle 5. In other words, the operator's hands will not be indirectly contaminated with paint 9 by gripping the handle 5.

[0043] As shown in Figure 7, the long-term storage lid 6 is a lid that covers the spray hole 12b from above. When the work is completed without using up the paint 9 below the lid body 1b and the paint 9 below the lid body 1b is to be stored, the long-term storage lid 6 can be used to cover the spray hole 12b, thereby enabling long-term storage of the paint 9.

[0044] As shown in Figure 9(a), a female thread 96 is formed on the inner circumferential surface of the long-term storage lid 6, and a male thread 95 is formed on the outer circumferential surface of the ejection part 11b, as shown in Figure 9(a). As shown in Figure 9(a), by screwing the female thread 96 of the long-term storage lid 6 onto the male thread 95 of the ejection part 11b, the paint 9 below the lid body 1b can be reliably sealed by the long-term storage lid 6.

[0045] Furthermore, if the paint container lid 100c has a lid (not shown) that covers its opening 81, the spraying part 11b can be closed with the long-term storage lid 6, and the paint container lid 100c can be closed with the lid (not shown) that covers the opening 81 that the paint container lid 100c had, thereby enabling long-term storage of the paint 9 located between the spraying part 11b above the lid body 1b and the upper part of the lid stand 4 73.

[0046] Furthermore, the handle 5 and the long-term storage lid 6 are also applicable to the paint container lid 100a described in the first embodiment above. When the handle 5 is applied to the paint container lid 100a, the lid body 1a is moved when the handle 5 is operated.

[0047] Furthermore, the long-term storage lid 6 may have an elongated shape extending upwards, as shown in Figure 9(b). In this case, even if a large amount of paint 9 remains between the spray nozzle 11b above the lid body 1b and the upper part of the lid stand 4 73, the paint 9 below the lid body 1b can be reliably sealed by pinching the upper part of the long-term storage lid 6 with the fingers and screwing it onto the spray nozzle 11b, without staining the worker's fingers with paint.

[0048] Furthermore, although the paint container lids 100a, 100b, and 100c described in this book are made of polyethylene, the present invention is not limited to this, and other materials may be used.

[0049] Furthermore, in the paint container 8 described in this book, the rim 82 is curved outward so that its inner surface 84 is flush with the surface, but a paint container with a rim 82 that is curved inward is also acceptable. In that case, the outer periphery 2a of the lid that fits onto the rim 82 is formed in an appropriate shape so as to be able to fit onto the rim 82, and the outer periphery 2b of the lid that is pressed against the inner surface 84 of the paint container 8 can be used to attach the paint container lid 100b or 100c to the paint container 8 by slightly bending the lid 100b or 100c and inserting it into the interior 83 of the paint container 8 through the opening 81, thereby pressing the outer periphery 2b of the lid against the inner surface 84 of the paint container 8 in an appropriate position.

[0050] Furthermore, although the paint container 8 described in this book was a circular bucket-shaped container, it may also be a rectangular or other shape.

[0051] Furthermore, although the entire expandable portion 3 of the paint container lid 100a was formed in a bellows shape, the present invention is not limited to this, and as long as the lid body portion 1a reaches the bottom 85 of the inside 83 of the paint container 8 when the outer circumference portion 2a of the lid is fitted onto the edge 82 of the paint container 8, only a part of the expandable portion 3 may be bellows-shaped.

[0052] Furthermore, although the upper part 4 of the lid stand of the paint container lids 100b and 100c was formed in a stepped shape by a single stepped section 41, the present invention is not limited to this, and may be formed in a stepped shape by multiple steps.

[0053] Furthermore, the reason why the outer circumference 2b of the paint container lids 100b and 100c is formed in a C-shape that opens downwards is that the inner circumference of the interior 83 of the paint container 8 is tapered and narrows downwards, so when the paint container lids 100b and 100c are pressed downwards, the outer circumference 2b of the lid continues to press against the inner surface 84 of the paint container 8 in accordance with the change in the inner circumference of the interior 83 of the paint container 8. The present invention is not limited to this, and the shape of the outer circumference 2b of the lid is acceptable as long as it continues to press against the inner surface 84 of the paint container 8. In addition, it is desirable that the outer circumference 2b of the lid is shaped to press against the inner surface 84 of the paint container 8 in a surface manner in order to prevent the paint container lids 100b and 100c from rotating inside the interior 83 of the paint container 8.
