Description

  The present invention relates to a structure of an inner lid of a putty container for storing and storing a highly viscous liquid such as an interior putty.

  Gypsum board and plywood are used as interior base materials for wallpaper construction. Prior to wallpaper construction, putty construction is performed in order to smooth each base material (see, for example, Patent Document 1). Putty construction is used not only for the joint part of the base material, but also for fixing the base material to the lightweight steel frame or wooden shaft, and to adjust the unevenness of the nail head.

  In order to adjust the unevenness between the base materials, a putty having a wide application width and a high adhesive strength that adheres to the base material or wallpaper even when thinly coated is required. On the other hand, in order to adjust the unevenness of screws and nail heads, a small coating area is sufficient and there is no need for strong adhesion strength. Usually, a lot of screws and nails are driven into the fixing of the base material, and as a necessary characteristic, an exclusive putty that cures in a short time is desired with extremely little fraying. Specifically, a water-based kneading putty that is preliminarily kneaded so that it can be applied immediately at any time is preferred because it contains a large amount of filler in order to shorten the time and drying time.

JP 2001-40277 A

  As described above, the screw and nail head putty are kneaded putties with a short drying time after application. Therefore, when the sealedness of the filled container is deteriorated, drying starts immediately from the inner surface of the container and hardens. In addition, if there is a space between the contents surface in the container and the sealed upper lid, water vapor evaporated from the contents fills the container. The full water vapor condenses and stays on the putty surface as the temperature changes. Since the moisture content of the surface portion of the putty is different, there are problems such as extending the drying time or reducing the adhesion strength.

  Although the screw and nail head have many application locations, the application amount may be very small, so it is convenient if there is a spatula that can remove the contents from the container little by little as necessary. The takeout spatula may be small enough to fit in a container, and it is convenient to use a plastic that can easily clean the putty put on. However, such a small plastic spatula was easily lost without a dedicated storage location.

  An object of the present invention is to obtain an inner lid for a putty container that can be stored by temporarily fixing a spatula for taking out in a fixed position while preventing internal dew condensation in the putty container for containing an aqueous putty. To do.

An inner lid for a putty container according to the invention described in claim 1 is composed of all or part of a cross-sectional shape that can be loosely fitted to an inner wall of a putty container that can be releasable at an upper portion that accommodates a highly viscous putty. A putty container inner lid provided with a bottom surface part that comes in contact with and a side wall part that rises upward from the entire periphery of the bottom surface part,
The inner lid is made of polypropylene;
A spatula mounting part for mounting a spatula in a vessel part surrounded by a bottom surface part and a side wall part ,

A putty container inner lid according to a third aspect of the present invention is characterized in that a thin film that contacts the inner wall of the putty container is formed on the upper edge of the side wall portion according to the first or second aspect. Is.

  The present invention has an effect that a takeout spatula can be temporarily fixed and stored in a fixed position while preventing internal dew condensation in a putty container containing an aqueous putty.

It is a top view which shows the structure of one Example of the container inner lid for putty. It is a front view of FIG. It is a rear view of FIG. It is a bottom view of FIG. It is a right view of FIG. It is a left view of FIG. It is AA sectional drawing of FIG. 1, and the enlarged view of the principal part is included. FIG. 2 is a perspective view of FIG. 1. It is explanatory drawing which shows the use condition of the container inner lid for putty. It is explanatory drawing which shows another use condition of the container inner lid for putty.

In the present invention, the upper part that accommodates the high-viscosity putty consists of all or part of the cross-sectional shape that can be loosely fitted to the inner wall of the releasable putty container, An inner lid for the putty container provided with a side wall portion that rises upward from the entire peripheral edge, the inner lid being made of a material to which the putty is difficult to adhere , and a spatula in a vessel portion surrounded by the bottom surface portion and the side wall portion A finger that can be inserted into the central part of the knob part, and a knob part for picking up the inner lid from the putty container is installed on the upper edge part of the side wall part. It placed holes that are openably formed. Accordingly, the takeout spatula can be temporarily fixed at a fixed position and stored while preventing internal dew condensation in the putty container containing the aqueous putty.

  The inner lid of the present invention is brought into contact with the putty surface of the putty container. For this reason, the position gradually falls below the putty container according to the amount of putty. For this reason, as a preferable aspect, in order to take out the inner lid out of the putty container at the time of use, a knob part for picking up from the putty container is provided at the upper edge of the side wall part.

  The inner lid of the present invention includes a spatula mounting portion for mounting a spatula in a vessel portion surrounded by a bottom surface portion and a side wall portion. For this reason, the spatula for scraping can be hold | maintained in a container, and workability | operativity improves. As a preferred embodiment, the concave portion matching the outer shape of the spatula is formed on the bottom surface portion, so that the spatula itself is less lost.

  The inner lid of the present invention includes a bottom surface portion and a side wall portion that rises upward from the entire peripheral edge portion of the bottom surface portion. The bottom part may be made of all or part of the cross-sectional shape that can be loosely fitted to the inner wall of the putty container. When the bottom surface portion comes into contact with the putty surface, generation of water vapor from the putty surface is prevented, thereby preventing internal condensation. Therefore, it is preferable that the bottom portion coincides with the bottom surface of the putty container to prevent generation of water vapor from the putty surface.

  However, in many containers such as putty containers, the upper opening is wider than the bottom. For this reason, even if the bottom surface portion of the inner lid is shaped to match the bottom surface of the container, the diameter is enlarged above the container, so that water vapor reaches the inside of the container through a gap formed around the inner lid. For this reason, as a preferred embodiment, a thin film that contacts the inner wall of the putty container is formed on the upper edge of the side wall.

  The inner lid of the present invention may be any material that does not easily adhere to putty, and is preferably made of plastic. Moreover, although it can be shape | molded if it is a thermoplastic resin sheet, Preferably workability, such as vacuum forming, is favorable by using what has flexibility, such as a polypropylene resin.

  FIG. 1 is a plan view showing a configuration of an embodiment of a putty container inner lid. FIG. 2 is a front view of FIG. FIG. 3 is a rear view of FIG. FIG. 4 is a bottom view of FIG. FIG. 5 is a right side view of FIG. FIG. 6 is a left side view of FIG. FIG. 7 is a cross-sectional view taken along the line AA of FIG. FIG. 8 is a perspective view of FIG. FIG. 9 is an explanatory view showing a use state of the putty container inner lid. FIG. 10 is an explanatory view showing another use state of the inner lid of the putty container.

  As shown in the figure, the putty container inner lid 10 of the present embodiment is made of polypropylene, which is a thermoplastic resin, and a bottom surface portion 11 and a bottom surface for placing on a putty surface of a putty container that contains an aqueous putty. The side wall portion 12 rises from the periphery of the portion 11.

  The bottom surface portion 11 does not extend over the entire circumference, but a part of the side wall portion 12 is transferred to the inner surface side (corresponding to the 3 o'clock portion in FIG. 1), and the side wall portion 12 is opposed to the C shape. Thus, the knob portion 13 is configured. Although the upper surface of the knob part 13 is covered, a finger insertion hole 14 into which a finger can be inserted is formed in the center part so as to be openable and closable.

  As shown in FIG. 9, the bottom surface portion 11 of the inner lid 10 is brought into contact with the surface of the putty 21 of the putty container 20. For this reason, the position gradually falls below the putty container 20 according to the amount of the putty 21. For this reason, when taking out the putty, the inner lid 10 can be taken out of the putty container 20 by using the knob portion 13 and the finger insertion hole 14 in order to take the inner lid 10 out of the putty container 20.

  The bottom surface portion 11 is provided with a spatula placement portion 15 as a recess that matches the outer shape of the spatula 30. For this reason, the spatula 30 for taking out can be hold | maintained, workability | operativity improves, and the spatula 30 itself is less lost.

  As shown in FIG. 9, most of the liquid surface of the putty 21 comes into contact with the bottom surface portion 11 of the inner lid 10, so that the evaporation of the moisture of the putty is largely suppressed, but the side wall portion 12 of the inner lid 10 A thin film 16 is further formed on the outer edge of the upper edge and the knob portion 13. The thin film 16 can prevent internal dew condensation in the putty container 20 containing the aqueous putty 21. As a result, even when the putty container 20 has a wider upper opening than the bottom surface, water vapor reaches the inside of the container 20 from the gap formed around the inner lid 10.

  The thin film 16 is made of polypropylene of the same material as the inner lid 10 body, and is formed by thinly extending the material when the inner lid 10 is molded. In the present embodiment, the same material as that of the inner lid body is formed at the same time as the molding, but a rubber material having higher flexibility may be additionally attached after the molding of the inner lid 10 body.
