Description

[Technical Field]

[0001] This invention relates to a paint container for painting wallpaper on walls. [Background technology]

[0002] Conventional paint containers for painting wallpaper on walls range from wide-mouthed bottles for small amounts to tin cans at their largest. Paint containers of about 1 liter size consist of a cylindrical container body with a circular rim on the top of the bottomed part, and a lid that fits over the circular rim to close the opening. Polyethylene cans are also available. Traditionally, all types of containers have contained highly viscous, highly concentrated wallpaper paint concentrate.

[0003] When painting, to obtain paint of the desired color and appropriate viscosity, paint containers containing one or more colors of concentrate are prepared, the required amount of concentrate and thinner is transferred into a separate container or roller bucket, and then stretched or mixed with a roller to create wallpaper paint of the desired color, concentration, and viscosity. This wallpaper paint is then applied to a roller or applicator brush, and used to apply it to the wallpaper on the wall. If the viscosity is too high, it will not be applied evenly and will be prone to unevenness, so the concentration must be adjusted to get closer to the desired color.

[0004] The thinner used varies depending on the type of paint. For water-based paint, water or a special reducer is used, for solvent-based paint, paint thinner is used, and for lacquer paint, lacquer thinner is used. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-200056 [Patent Document 2] Japanese Patent Application Laid-Open No. 2005-15057 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventionally, products containing undiluted paint in tin or polyethylene cans have been sold, but there are no products on the market that contain wallpaper paint in containers such as PET bottles, adjusted to the desired color, concentration, and viscosity.

[0007] When a user wanted a wallpaper paint in a color that was not commercially available, they had to procure multiple different colors of wallpaper paint and mix them in the required proportions, but it was surprisingly difficult to obtain the desired color. When the amount of viscosity-adjusted paint was insufficient, it was necessary to make viscosity-adjusted paint again, but it was difficult to make viscosity-adjusted paint with the exact same desired color, concentration, and appropriate viscosity as before. Therefore, it was necessary to make a large amount of viscosity-adjusted paint with the desired color, concentration, and appropriate viscosity, and any excess had to be discarded, which was wasteful.

[0008] Therefore, the inventor of the present application came up with the idea of ​​providing a product in the form of a cup container containing viscosity-adjusted paint, which is made by preparing viscosity-adjusted paint of the desired color, concentration and appropriate viscosity, placing it in a cup container, and removably closing it with an aluminum foil stopper; also providing a product with an outlet cap that is a narrow cylindrical shape in the center of the top surface, with an outlet at the top end and a hinged lid stopper on the outlet; and further providing a product in the form of a bottle-shaped container containing paint, which is made by covering the above-mentioned cup container containing viscosity-adjusted paint without an aluminum foil stopper with the above-mentioned outlet cap and screwing it shut.

[0009] To use these, one purchases one of the above-mentioned bottle-shaped containers of paint and the required number of cup containers of the same color of viscosity-adjusted paint according to the area of ​​the surface to be painted, removes the lid of the cup container of viscosity-adjusted paint, turns it upside down, and presses the paint outlet of the outlet cap against the brush of a wall painting brush while moving it, thereby applying viscosity-adjusted paint onto the brush, and then paints the wall with the brush, and when the brush runs out of paint, viscosity-adjusted paint can be applied onto the brush as many times as necessary.When the paint in the cup container runs out, the cup container of viscosity-adjusted paint is removed, and the aluminum foil of another cup container of viscosity-adjusted paint that has been purchased is removed, and the cap with the outlet is replaced, screwed on and sealed, and it can be used again.

[0010] The present invention was developed in consideration of the above idea, and aims to provide a paint container that can be separated into an upper and lower bottle-shaped container containing paint with a viscosity that can be used immediately, and a paint container that can be used to form a lower container containing viscosity-adjusted paint that is peelably closed with aluminum foil. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the paint container of the present invention is characterized by comprising a bottomed cylindrical lower container body, an upper container body that is screwed onto the lower container body and functions as a cap, a small-diameter cylindrical portion extending upward from the center of the upper container body, and a lid that is supported by a hinge attached to one side of the small-diameter cylindrical portion and opens and closes the paint outlet at the upper end of the small-diameter cylindrical portion.

[0012] The upper portion of the container body preferably has a large diameter cylindrical portion, a small diameter cylindrical portion, and a truncated conical cylindrical portion between the large diameter cylindrical portion and the small diameter cylindrical portion.

[0013] The upper end of the lower container body and the lower end of the upper container body are preferably configured so that a male thread provided on one of them and a female thread provided on the other are threadably engaged with each other.

[0014] It is preferable that the lower part of the container body is covered with aluminum foil after the viscosity-adjusted paint is placed therein and then screwed onto the upper part of the container body to form a cap, and that the aluminum foil be peeled off before use. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide a paint container that can be used to make a bottle-shaped paint container containing paint with a viscosity that can be used immediately, and a cup-shaped paint container containing viscosity-adjusted paint that is peelably closed with aluminum foil. [Brief explanation of the drawings]

[Figure 2] 1 is an overall perspective view of a paint container according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a paint container according to the present invention will be described below with reference to the drawings.

[0018] 1 and 2 show a paint container according to an embodiment of the present invention. This paint container 1 is characterized by comprising a bottomed cylindrical (cup-shaped) lower container body 2, an upper container body 3 that functions as a cap and is screwed onto the upper end of the lower container body 2, a small-diameter cylindrical portion 3b extending upward from the center of the upper container body 3, and a lid 5 that is supported by a hinge 4 attached to one side of the small-diameter cylindrical portion 3b and that opens and closes the paint outlet at the upper end (tip) of the small-diameter cylindrical portion 3b. The upper container body 3 and the upper container body 3 are made of plastic, such as a PET bottle.

[0019] The upper container body 3 comprises a large-diameter cylindrical portion 3a, a small-diameter cylindrical portion 3b, and a truncated conical portion 3c between the large-diameter cylindrical portion 3a and the small-diameter cylindrical portion 3b. Therefore, when the paint container 1 is turned upside down, the viscosity-adjusted paint in the lower container body 2 flows smoothly through the truncated conical portion 3c, enters the small-diameter cylindrical portion 3b, and can flow out from the paint outlet at the tip.

[0020] In Figure 1, the lower end 3d of the upper container body 3 covers the upper end 2a of the lower container body 2, and a male threaded portion 6 is provided on the outer periphery of the upper end of the lower container body 2, and a female threaded portion 7 is provided on the inner periphery of the lower end of the upper container body 3, so that the male threaded portion 6 and the female threaded portion 7 are screwed together and sealed.

[0022] At the distribution stage, the lower container body 2 is filled almost to the brim with viscosity-adjusted paint, and then aluminum foil 8 is affixed to the top surface and the upper container body 3 is screwed onto the cap, with the aluminum foil 8 being peeled off when the product is used after purchase. The aluminum foil 8 does not have to be present. In this case, it is not necessary to peel off the aluminum foil 8. The configuration in which the lower container body 2 contains paint and is covered with aluminum foil 8 without the upper container body 3 is intended for common use, with the lower container body 2 being sold as a spare.

[0023] According to the present invention, during manufacturing, the lower container body 2 and the upper container body 3 are molded from plastic, and viscosity-adjusted paint that can be used directly is placed into the lower container body 3, and aluminum foil 8 is attached to the top end of the lower container body 2, and then the upper container body 3 is screwed on to form a bottle-shaped paint container.When using after purchase, the upper container body 3 is removed, the aluminum foil 8 is peeled off, and the upper container body 3 is reassembled.The lid 5 is removed to open the paint outlet in the small-diameter cylindrical portion 3b of the upper container body 3, and an appropriate amount is placed on the brush of a wall painting brush with the brush facing downward, and the wall is painted with the paint brush without the need to adjust the viscosity.

[0024] Therefore, according to the present invention, it is possible to provide a paint container 1 that can be used to make a bottle-shaped paint container containing paint with a viscosity that can be used immediately, and a cup-shaped paint container containing viscosity-adjusted paint that is peelably closed with aluminum foil.
