Description
[Technical field]
[0001] The present invention relates to a bowl having a bowl body and a handle attached to the outer circumferential surface of the bowl body. [Background technology]
[0002] For example, a bowl as shown in Patent Document 1 below is already in practical use as nursing tableware for patients who have developed motor paralysis, more specifically motor paralysis of the fingers, due to sequelae of cerebral infarction, etc. Such a bowl has a bowl body and a handle attached to the outer periphery of the bowl body, and is stably supported by a user inserting his or her fingers between the bowl body and the handle and placing the palm of the user's hand on the outer periphery of the bowl body. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Utility Model Registration No. 3072349 Summary of the Invention [Problem to be solved by the invention]
[0004] Incidentally, the rim of a bowl or bowl body is usually circular in plan view. This allows the user to place their mouth on any angle position of the rim to eat or drink contents such as rice or soup. Even if the rim of the bowl body in the bowl shown in Patent Document 1 is circular in plan view, a user who is a patient suffering from motor paralysis can support the bowl body as described above to eat or drink contents such as rice or soup. However, when the user supports the bowl body as described above, the angle position at which the user places their mouth on the rim is uniquely determined to a certain extent, so the rim does not necessarily need to be circular in plan view, and the shape of the rim can be reconsidered to make it easier for the user to eat and drink.
[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its main technical object is to provide a new and improved bowl with a handle and a rim that is easy to use. [Means for solving the problem]
[0006] According to the present invention, as a bowl that solves the above-mentioned main technical problem, there is provided a bowl having a bowl body and a handle attached to an outer peripheral surface of the bowl body, The present invention provides a bowl characterized in that, in a plan view, a line that passes through the widthwise center of the handle and extends in the direction in which the handle extends is defined as a first line, two points on the rim of the bowl body that intersect with the first line are defined as a first point and a second point, a midpoint between the first point and the second point is defined as a third point, and a line that passes through the third point and is perpendicular to the first line is defined as a second line, the rim has a singular point on the opposite side to the handle from the second line and in a circumferential angular region between the second line and the first line, centered on the third point, where the distance from the third point is maximum.
[0007] Preferably, the singular point is disposed at an angle of 10 to 40 degrees from the second line toward the first line with respect to the third point. The distance from the third point to the singular point is preferably 105 to 145% of the distance from the third point to the second point. In a plan view, the rim is preferably symmetrical with respect to the first line. Preferably, the height of the rim at the second point is lower than the height of the rim at the first point when the side to which the handle is attached is defined as the first point. The handle preferably includes a curved portion curved so as to be convex upward in a direction away from the outer circumferential surface of the bowl body, and an extension portion extending downward from the curved portion to the lower end of the bowl body when viewed in the up-down direction, and the distance between the inner surface of the extension portion and the outer circumferential surface of the bowl body is gradually reduced downward. The bottom of the recess of the bowl body is preferably circular in plan view. In this case, the center of the bottom of the recess is preferably aligned with the third point in plan view. Also, it is preferable that the bowl body has a pedestal, and the center of the pedestal is preferably aligned with the center of the bottom of the recess in plan view. Effect of the Invention
[0008] In the bowl of the present invention, in a plan view, the rim of the bowl body is located on the opposite side of the handle from the second line and has a singular point in a circumferential angular region between the second line and the first line, with the third point as the center, at a maximum distance from the third point. Therefore, the curvature near the singular point is relatively large, and the vicinity of the singular point functions like a spout. The position where such a singular point exists is close to the mouth of the user when the user inserts his / her fingers between the bowl body and the handle and supports the outer circumferential surface of the bowl body with his / her palm. Therefore, even if the user is a patient with motor paralysis, he / she can easily eat and drink the contents by putting his / her mouth to the singular point after or while scraping the contents with a spoon or the like toward the singular point.

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a more detailed description will be given with reference to the accompanying drawings showing a preferred embodiment of a bowl constructed according to the present invention.
[0011] 1 to 7, a bowl generally designated by the numeral 2 comprises a bowl body 4 and a handle 6 attached to the outer periphery of this bowl body 4. The bowl body 4 further comprises a rim 8 which is a noncircular closed curve having a required shape as described below, a tubular body 10 which hangs down from the rim 8, a waist 12 which hangs down further from the bottom end of the body 10 and then closes the bottom, and a pedestal 14 which supports the waist 12, and a recess 16 is defined on the inside of the body 10 and the waist 12.
[0012] For convenience, the handle 6 will be described first. The handle 6 is a thin plate with one end connected to the upper end of the outer circumferential surface of the body 10 at a required circumferential position, and has a required widthwise length. The handle 6 is divided into a curved portion 18 that is curved from the one end as a starting point so as to be convex upward in a direction away from the outer circumferential surface of the bowl body 4, and an extending portion 20 that extends downward along the outer circumferential surface of the bowl body 4 from the end point of the curved portion 18. The other end of the handle 6, i.e., the lower end of the extending portion 20, is a free end, and is located at the lower end of the bowl body 4 when viewed in the vertical direction. As shown in Fig. 7, the distance D between the inner surface of the extending portion 20 and the outer circumferential surface of the bowl body 4 is gradually reduced downward.
[0013] Next, the bowl body 4 will be described. Mainly referring to Fig. 3, in a bowl constructed according to the present invention, in a plan view, if a straight line passing through the widthwise center of the handle 6 and extending in the direction in which the handle 6 extends is defined as a first straight line L1 (two-dot chain line), two points on the rim 8 of the bowl body 4 that intersect with the first straight line L1 are defined as a first point P1 and a second point P2 (the side to which the handle is attached is defined as the first point P1, and the opposite side is defined as the second point P2), the midpoint between the first point P1 and the second point P2 is defined as a third point P3, and a straight line passing through the third point P3 and perpendicular to the first straight line L1 is defined as a second straight line L2 (two-dot chain line), it is important that the rim 8 has a singular point that is the maximum distance from the third point P3, which is located on the opposite side of the second straight line L2 from the handle 6 and is located in a circumferential angle region between the second straight line L2 and the first straight line L1 with the third point P3 as the center. In the illustrated embodiment, the rim 8 is symmetrical with respect to the first straight line L1 in a plan view, and therefore has two singular points PX1 and PX2. The singular points are preferably located at an angle of 10 to 40 degrees from the second straight line L2 toward the first straight line L1 with respect to the third point P3, and in the illustrated embodiment, the singular points PX1 and PX2 are each located at an angle of 26 degrees from the second straight line L2 toward the first straight line L1 with respect to the third point P3. The distance from the third point P3 to the singular points is preferably 105 to 145% of the distance from the third point P3 to the second point P2, and in the illustrated embodiment, the former distance is set to 125% of the latter distance. Furthermore, as can be clearly understood by referring to FIG. 2 together with FIG. 3, the height of the rim 8 at the second point P2 is lower than the height of the rim 8 at the first point P1.
[0014] The outer and inner peripheral surfaces of the torso 10 and waist 12 are both inclined downward and inward. The inner and outer peripheral surfaces of the torso 10 and the inner peripheral surface of the waist 12 are flat, but the outer peripheral surface of the waist 12 has multiple annular ridges 22 that extend continuously in the circumferential direction and are spaced apart in the vertical direction.
[0015] 3, the bottom 24 of the projection 16 is circular in plan view. In the illustrated embodiment, the center of the bottom 24 of the projection 16 is aligned with the third point P3 in plan view. As can be understood by referring to FIGS. 2, 4, and 7, the plateau 14 is cylindrical, and the center of the plateau 14 is aligned with the center of the bottom 24 of the projection 16 in plan and bottom views.
[0016] Next, the manner of using the bowl 2 will be described with reference to FIG. 8. When a user uses the bowl 2 together with a spoon (not shown) to eat or drink contents such as rice or soup, the user inserts one of the fingers between the bowl body 4 and the handle 6 to support the outer circumferential surface of the bowl body 4 with the palm of the hand and grasps the spoon with the fingers of the other hand. In this case, in the illustrated embodiment, the handle 6 has a curved portion 18 that is curved so as to be convex upward in a direction away from the outer circumferential surface of the bowl body 4, and an extension portion 20 that is continuous with the curved portion 18 and extends downward to the lower end of the bowl body 4 when viewed in the up-down direction. Therefore, the user's fingers, especially the side of the index finger, are stably supported on the inside of the curved portion 18. Furthermore, the distance between the inner surface of the extension portion 20 and the outer circumferential surface of the bowl body 4 is gradually reduced downward, so that the user's palm is prevented from moving away from the outer circumferential surface of the bowl body 4. Thus, the user can stably support bowl 2. Then, after or while scraping up the contents in bowl body 4, the user places his / her mouth on the rim and eats / drinks the contents. The movement of the spoon at this time, that is, the path of the spoon entering bowl 16, is shown by arrow R1, and the path of the spoon exiting bowl 16 is shown by arrow R2.
[0017] In this case, in the bowl of the present invention, in a plan view, the rim 8 of the bowl body 4 is on the opposite side of the handle 6 from the second straight line L2, and has singular points PX1 and PX2 that are the maximum distance from the third point P3 in the circumferential angle region between the second straight line L2 and the first straight line L1 centered on the third point P3, so that the curvature near the singular points PX1 and PX2 is relatively large, and the vicinity of the singular points PX1 and PX2 functions like a spout. The position where such singular points PX1 and PX2 exist is close to the mouth of the user when the user inserts his / her fingers between the bowl body 4 and the handle 6 and supports the outer circumferential surface of the bowl body 4 with his / her palm. Therefore, even if the user is a patient who has developed motor paralysis, he / she can easily eat and drink the contents by putting his / her mouth to the singular point PX1 or PX2 after or while scraping the contents with a spoon or the like toward the singular point PX1 or PX2.
[0018] In the illustrated embodiment, in plan view, the rim 8 is line-symmetrical with respect to the first straight line L1 and has two singular points PX1 and PX2, so that whether the user holds the bowl 2 with the left or right hand, the singular point PX1 or PX2 will be on the side closest to the mouth when the user holds the bowl 2. At this time, the tip of the spoon held with the fingers of the other hand moves from near the singular point PX1 of the rim into the projection 16, passing through the center of the projection 16, to the singular point PX2 of the rim 8, or moves from the singular point PX2 of the rim into the projection 16, passing through the center of the projection 16, to the singular point PX1 of the rim 8, making it easier to handle the spoon. In the illustrated embodiment, the height of the rim 8 at the second point P2 is lower than the height of the rim 8 at the first point P1, so that a person cleaning the bowl 2 can easily discard the contents of the bowl 2 by holding the handle 6 with one hand and moving the second point P2 side of the rim 8 downward while using the other hand to scoop out the contents. Furthermore, in the illustrated embodiment, the center of the bottom 24 of the recess 16 is aligned with the third point P3 in a plan view, so that the weight balance of the bowl body 4 is good despite the rim 8 being noncircular, and the bowl body 4 is easy to use. Furthermore, the center of the foot 14 is aligned with the center of the bottom 24 of the recess 16, so that the stability of the bowl body 4 is good.
[0019] Although the bowl constructed according to the present invention has been described in detail above with reference to the attached drawings, the present invention is not limited to the above-mentioned embodiment, and appropriate modifications and changes are possible within the scope of the present invention. For example, the illustrated embodiment has a pedestal 14, but this may be omitted. Just to be clear, the bowl constructed according to the present invention is not limited to being used as nursing tableware for patients who have developed motor paralysis of the fingers, but can be used for any purpose, such as tableware for the elderly and children.
