Embodiments according to the present invention will be described below with reference to the drawings. However, the scope of the present invention is not limited to the illustrated example.
First, the configuration of the flower clip 1 in this embodiment will be explained.
FIG. 1 is a perspective view of a flower clip 1 in an embodiment.
FIG. 2 is a six-sided view illustrating the flower clip 1. 2(A) is a plan view, FIG. 2(B) is a bottom view, FIG. 2(C) is a front view, and FIG. 2(D) is a right side view. Note that the rear view is omitted because it is symmetrical with the front view, and the left side view is omitted because it is symmetrical with the right side view.
FIG. 3 is an end view illustrating a section cut along the line AA of the flower clip 1 illustrated in FIG. 2.

As illustrated in FIGS. 1 and 2, the flower holder 1 is a casting made of a copper alloy casting, and is formed by sand casting. The flower clip 1 has a flower clip main body 10 and a through hole 20.
The flower clasp body 10 is a main body of the flower clasp 1 that is made of a casting of copper or a metal (copper alloy) containing copper as a main component. The flower holder main body 10 has a cylindrical or prismatic shape. That is, the flower holder main body 10 has a columnar shape.
Moreover, the side surfaces, top surface, and bottom surface of the flower holder main body 10 are polished over the entire surface so as to give off a metallic luster. That is, at least a portion of the top and bottom surfaces of the flower holder main body 10 are polished. Here, the top surface of the flower clasp body 10 in this example refers to the end surface of the flower clasp body 10 illustrated in FIG. 2(A), and the bottom surface of the flower clasp body 10 illustrated in FIG. 2(B). The end face of the flower clip main body 10 is shown.
Further, the size of the flower clasp body 10 is, for example, a diameter of 5 cm or more and 7 cm or less, and a thickness of 2 cm or more and 4 cm or less. , with a thickness of 2.5 cm.

As illustrated in FIGS. 2 and 3, a plurality of through holes 20 are provided in the cylindrical flower clasp main body 10 and penetrate from the top surface to the bottom surface. In the through-hole 20, the opening size of the through-hole located on the top surface illustrated in FIG. 2(A) is larger than the opening size of the through-hole located on the bottom surface illustrated in FIG. 2(B). Specifically, focusing on the through holes 20A to 20D illustrated in FIG. 3, the opening width D of the through hole located on the top surface is wider than the opening width d of the through hole located on the bottom surface. The hole 20 gradually narrows from the top surface to the bottom surface so as to connect the openings on the top surface and the bottom surface. Further, the thickness of the wall surface located between two adjacent through holes 20 gradually increases from the top surface to the bottom surface.
Further, the wall surface 22 of the through hole 20 has an uneven surface that is not flat. The wall surface 22 of the through hole 20 has a surface roughness that corresponds to the grain size of the sand used in sand casting, and is unpolished. Therefore, the wall surface 22 of the through hole 20 has a rougher surface than the polished top surface, bottom surface, and side surface of the flower holder main body 10. Note that the surface roughness of the wall surface 22 of the through hole 20 can be changed as appropriate depending on the grain size of the sand used in the sand mold. The wall surface 22 has a large surface area by making the surface rough.

Next, the flower clip 1 in use will be described.
FIG. 4 is a diagram illustrating the flower clip 1 with a plant P arranged thereon. FIG. 4(A) is a perspective view illustrating the flower clip 1 with a plant P arranged thereon, and FIG. 4(B) is a cross-sectional view of the flower clip 1 with the plant P arranged thereon.
As illustrated in FIG. 4(A), the flower clasp 1 is placed in a vase V filled with water in a submerged state. The flower clip 1 fixes the plant P in an upright position. By placing the flower clip 1 submerged in water, copper is eluted into the water. Thereby, the flower clip 1 can prevent the proliferation of various germs due to the bactericidal action of the copper (so-called copper ions) eluted into the water. Therefore, the plant P can be kept for a long time. Further, since the through hole 20 has an unpolished and rough wall surface 22, the area that comes into contact with water can be increased. Thereby, the flower retainer 1 easily dissolves copper ions at a high concentration into the water.

In addition, as illustrated in FIG. 4(B), the base end of the plant P can be bent like the base end A of the plant P, or the base end of the plant P can be bent like the base end B of the plant P. In this case, the plant P is inserted into the through hole 20 with the base end of the plant P in a straight state without being bent. When the plant P is inserted while pushing the base end into the through hole 20 from the top to the bottom, the wall 22 of the through hole 20, which gradually narrows from the top to the bottom, gradually closes the plant P. The proximal end is pressed and pinched. Thereby, the flower clip 1 can fix the plant P in an upright state. At this time, the base end of the plant P is caught on the unevenness of the wall surface 22 of the through hole 20, so the flower clip 1 can fix the plant P more firmly.

Next, a method for manufacturing the flower clip 1 in the embodiment will be described.
FIG. 5 is a flowchart illustrating the method for manufacturing the flower clip 1 (S10) in the embodiment.
As illustrated in FIG. 5, in step 100 (S100), the manufacturer pours molten copper alloy into a sand mold.
In step 102 (S102), after the copper alloy poured into the mold cools and hardens, the manufacturer takes out the flower clasp body 10 from the mold. The flower clip main body 10 taken out has a columnar shape with a through hole 20 provided therein. The manufacturer removes sand from the flower clasp body 10 taken out and removes sprues and burrs.
In step 104 (S104), the manufacturer polishes only the side, top and bottom surfaces of the flower holder main body 10 until they have a metallic luster. That is, the manufacturer polishes the surface of the flower holder main body 10, excluding the wall surface 22 of the through hole 20, until it has a metallic luster. Thereby, it is possible to improve the design of the flower clip 1 and to prevent injury to the user's hands and fingers during use. Furthermore, by polishing the top and bottom surfaces of the flower holder main body 10, the surface on which the vase V is placed and the plant P can be prevented from being damaged. Then, the manufacturer can obtain the flower clip 1.

As explained above, according to the flower clasp 1 of this embodiment, copper ions can be contained in the water in which plants are kept by being made of copper alloy casting. This prevents the growth of bacteria in the water, allowing plants to last longer.

In addition, in this embodiment, the case where the through-hole 20 is formed so that the axial direction of the through-hole 20 is substantially perpendicular to the top surface and the bottom surface of the flower holder body 10 has been described, but the axis of the through-hole 20 The through-hole 20 may be formed so that the direction is inclined with respect to the top and bottom surfaces of the flower holder main body 10.
Furthermore, in the present embodiment, the case where the flower holder main body 10 is made of copper alloy casting has been described, but for example, the flower holder main body 10 may be formed of a casting made of non-antibacterial metal or ceramics, An antibacterial metal film may be formed on the surface of the main body 10. Examples of antibacterial metals include tin, copper, and silver.
