本発明は容器である。この本発明の容器は、容器本体と、この容器本体の開口部を閉蓋する天面部および側面部を有する蓋体とを具備する。前記蓋体は、蓋体の側面部の内面に付着した水滴が前記容器本体内に落下するのを誘導する為の水滴落下誘導用凸部を具備する。この水滴落下誘導用凸部は前記蓋体の側面部内面に設けられている。前記水滴落下誘導用凸部は、好ましくは、前記蓋体の側面部の内面に付着した水滴の前記容器本体内への落下誘導位置が該容器本体における稜線部より内側の位置であるように設けられている。そして、前記水滴落下誘導用凸部は、特に、好ましくは、その横幅寸法が上部から下部に向って連続的に小さくなる形状に構成されている。中でも、後述の上側面部と後述の拡幅面部との境界部（境界ライン）より上方の位置から前記境界部（境界ライン）より下方の位置に亘って水滴落下誘導用凸部は設けられており、そして該水滴落下誘導用凸部は、その横幅寸法が上部から下部に向って連続的に小さくなる形状に構成されている。水滴落下誘導用凸部が設けられている側面部を正面から眺めた場合、水滴落下誘導用凸部は、例えば略Ｖ形状とか略Ｙ形状の如くに構成されているのが好ましい。斯くの如きの形状の場合に、水滴が、効果的に、容器本体内部に落下誘導される。前記水滴落下誘導用凸部は、好ましくは、その下端における横幅寸法が４ｍｍ以下（更には、３ｍｍ以下。中でも、２ｍｍ以下）である。尚、下限値は０でも良い。但し、下端においても幾許かの寸法が有るのが現実であろうかとも思われる。例えば、水滴落下誘導用凸部の下端における横幅寸法が、現実的には、短くても、０．０１ｍｍ程度は有るであろう。前記水滴落下誘導用凸部は、好ましくは、側面部に対する垂直な断面での形状が略レ字形状に構成されている。前記蓋体の側面部は、例えば天面部に繋がる上側面部と、前記上側面部の下端に繋がり、該上側面部の外側に拡がる拡幅面部と、前記拡幅面部の外端に繋がる下側面部とを有する。前記上側面部は、好ましくは、前記蓋体の閉蓋時において、前記容器本体の開口部の内側（後述の稜線部（上端平坦面部）より内側）に位置するよう構成されたものである。そして、前記水滴落下誘導用凸部は前記上側面部に設けられる。前記上側面部と前記拡幅面部との境界部（境界ライン）は、好ましくは、前記水滴落下誘導用凸部位置が最も下方に位置するよう傾斜（例えば、Ｖ形状に傾斜）して構成されたものである。そして、前記水滴落下誘導用凸部の下端部が前記境界部（境界ライン）よりも下側に突出しているよう構成されているのが好ましい。すなわち、このような構成とすることによって、水滴が、効果的に、容器本体内部に誘導されて落下する。前記蓋体の閉蓋時において、前記上側面部と前記容器本体とは、０．５ｍｍ以上（更には、０．７ｍｍ以上。特に、１ｍｍ以上。）で、４ｍｍ以下（更には、３ｍｍ以下。特に、２ｍｍ以下）の距離は離間しているよう構成されていることが好ましい。又、前記蓋体の閉蓋時において、前記拡幅面部と前記容器本体とは、０．５ｍｍ以上（更には、０．７ｍｍ以上。特に、１ｍｍ以上。）で、４ｍｍ以下（更には、３ｍｍ以下。特に、２ｍｍ以下）の距離は離間しているよう構成されていることが好ましい。すなわち、側面部（拡幅面部）と容器本体（稜線部：上端平坦面部）との間に隙間が無い場合、或いは小さな寸法の隙間しか無い場合には、蓋体の側面部に付着している水滴が毛細管現象によって拡幅面部と容器本体（稜線部：上端平坦面部）との間に嵌り込み、開蓋するまで、ここに、水滴は貼り付いてしまったかの如くになり、前記嵌まり込んでしまった水滴が容器本体内に誘導落下され難くなり、側面部と容器本体との間に嵌り込んだ水滴が開蓋した際に周囲に飛散し易い恐れが高かったからである。 The present invention is a container. The container of the present invention includes a container main body and a lid having a top surface portion and a side surface portion that closes the opening of the container main body. The lid includes a drop-dropping convex portion for guiding the water droplets attached to the inner surface of the side surface of the lid to fall into the container body. The water droplet drop guiding convex portion is provided on the inner surface of the side surface of the lid. Preferably, the water drop drop-inducing convex portion is provided such that a drop-inducing position of the water droplets adhering to the inner surface of the side surface portion of the lid body is a position inside the ridge line portion in the container body. It has been. The water drop dropping guidance convex portion is particularly preferably configured to have a shape in which the width dimension continuously decreases from the upper part toward the lower part. Among these, the drop-dropping convex portion is provided from a position above a boundary portion (boundary line) between an upper side surface portion described later and a widened surface portion described later to a position below the boundary portion (boundary line). The water drop dropping guide convex portion is configured to have a shape in which the width dimension is continuously reduced from the upper part toward the lower part. When the side surface portion on which the water drop dropping guidance convex portion is provided is viewed from the front, the water drop dropping guidance convex portion is preferably configured in, for example, a substantially V shape or a substantially Y shape. In the case of such a shape, the water droplet is effectively induced to fall inside the container body. Preferably, the water droplet drop guiding convex portion has a width dimension of 4 mm or less (further 3 mm or less, especially 2 mm or less) at the lower end thereof. The lower limit value may be 0. However, it seems that it is a reality that there are some dimensions at the lower end. For example, the width dimension at the lower end of the water droplet drop-inducing convex portion may actually be about 0.01 mm even if it is short. The protrusion for guiding the drop of water drop is preferably formed in a substantially letter shape in a cross section perpendicular to the side surface. The side surface portion of the lid body is, for example, an upper side surface portion that is connected to the top surface portion, a wide surface portion that is connected to the lower end of the upper side surface portion and extends outside the upper side surface portion, and a lower side surface portion that is connected to the outer end of the wide surface portion. And have. The upper side surface portion is preferably configured to be positioned inside the opening of the container main body (inside a later-described ridge line portion (upper flat surface portion)) when the lid body is closed. And the said drop drop guidance convex part is provided in the said upper side part. The boundary portion (boundary line) between the upper side surface portion and the widened surface portion is preferably configured to be inclined (for example, inclined in a V shape) so that the position of the water droplet drop guiding convex portion is located at the lowest position. Is. And it is preferable that it is comprised so that the lower end part of the said convex part for water drop fall guidance may protrude below the said boundary part (boundary line). That is, by setting it as such a structure, a water droplet is induced | guided | derived to a container main body inside effectively, and falls. When the lid is closed, the upper side surface portion and the container body are 0.5 mm or more (further 0.7 mm or more, particularly 1 mm or more) and 4 mm or less (further 3 mm or less). In particular, it is preferable that the distance is 2 mm or less). Further, when the lid is closed, the widened surface portion and the container body are 0.5 mm or more (more 0.7 mm or more, particularly 1 mm or more) and 4 mm or less (more 3 mm or less). In particular, it is preferable that the distance is 2 mm or less). That is, when there is no gap between the side surface portion (enlarged surface portion) and the container body (ridge line portion: upper end flat surface portion), or when there is only a small gap, water droplets adhering to the side surface portion of the lid Until the lid is opened by the capillary phenomenon until it is fitted between the widened surface part and the container body (ridge line part: upper flat surface part), and the water drops are stuck, and the above-mentioned is fitted. This is because the water drops are less likely to be guided and dropped into the container body, and there is a high possibility that the water drops fitted between the side surface and the container body are likely to be scattered around when the lid is opened.

他の本発明は蓋体である。すなわち、上記容器において用いられた蓋体である。言い換えるならば、上記容器における容器本体を除いた構成の蓋体である。 Another aspect of the present invention is a lid. That is, the lid used in the container. In other words, it is a lid body having a configuration excluding the container body in the container.

上側面部３ａ，３ｂ，３ｃ，３ｄと下側面部５ａ，５ｂ，５ｃ，５ｄとを連結している拡幅面部４ａ，４ｂ，４ｃ，４ｄは、図１，３，４，５，８，９，１０，１８からも判る通り、左右方向における真中位置が低く下がり、左右の両端部の位置で高く上がった形状（断面が、例えば略Ｖ形状）に成形されている。すなわち、蓋体Ｂで容器本体Ａの上方開口部５４を閉蓋した場合、拡幅面部４ａ，４ｂ，４ｃ，４ｄが容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄに対向して位置するものとなることから、拡幅面部４ａ，４ｂ，４ｃ，４ｄは、左右方向における真中位置が低く下がり、左右の両端部の位置で高く上がった形状（例えば、略Ｖ形状）に成形されている。尚、閉蓋時において、蓋体Ｂの拡幅面部４ａ，４ｂ，４ｃ，４ｄは容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄに対向して位置しているものの、蓋体Ｂの上側面部３ａ，３ｂ，３ｃ，３ｄおよび拡幅面部４ａ，４ｂ，４ｃ，４ｄと容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄとの間には、所定寸法、例えば０．７〜３ｍｍ程度（最も接近した箇所で０．７ｍｍ程度、最も離れた箇所で２〜３ｍｍ程度）の間隙が存するように容器本体Ａと蓋体Ｂとは構成されている。すなわち、蓋体Ｂは蓋であることから、閉蓋時には何処かの箇所（例えば、四隅の角部における下端部近傍の箇所）で蓋体Ｂは容器本体Ａに当接（掛止）しているものの、本実施形態の容器にあっては、蓋体Ｂの上側面部３ａ，３ｂ，３ｃ，３ｄおよび拡幅面部４ａ，４ｂ，４ｃ，４ｄは容器本体Ａに接触していない（図３参照）。そして、単に、当接していないと言うだけでは無く、所定の寸法（例えば、０．５ｍｍ）以上の距離が保たれるように離れている。これは、蓋体Ｂの上側面部３ａ，３ｂ，３ｃ，３ｄの内面に付着している水滴が内面に沿って下方に落ちて来た場合、蓋体Ｂの拡幅面部４ａ，４ｂ，４ｃ，４ｄと容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄとの間の隙間に水滴が毛細管現象によって入り込むのを効果的に防止する為である。つまり、蓋体Ｂの拡幅面部４ａ，４ｂ，４ｃ，４ｄと容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄとの間の隙間が小さいと、上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界ラインに落下して来た水滴は、毛細管現象によって、上記隙間に入り込み易いものの、蓋体Ｂの拡幅面部４ａ，４ｂ，４ｃ，４ｄと容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄとの間の隙間が上記の如く大きなものであると、水滴は、逆に、上記隙間に入り込み難いものとなる。従って、蓋体Ｂの拡幅面部４ａ，４ｂ，４ｃ，４ｄと容器本体Ａの上端平坦面部（稜線部）５０ａ，５０ｂ，５０ｃ，５０ｄとの間の隙間が上記の如きのものであることが好ましい。上側面部３ａ，３ｂ，３ｃ，３ｄの内面に沿って上方から下方に向かって拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界ライン（略Ｖ形状のライン）まで落下して来た水滴は、拡幅面部４ａ，４ｂ，４ｃ，４ｄが水平方向に外側に拡がった面であることから、その箇所で、それ以上は下方に落下することは無い。その代わり、上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界ラインが、上述の通り、略Ｖ形状に構成されていることから、その左右の箇所から真中の位置に滑り落ちて来るようになる。すなわち、上側面部３ａ，３ｂ，３ｃ，３ｄの最も低い位置（左右方向において略真中の位置）に水滴が集って来るように上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界ラインが構成されている。 The widened surface portions 4a, 4b, 4c, 4d connecting the upper side surface portions 3a, 3b, 3c, 3d and the lower side surface portions 5a, 5b, 5c, 5d are shown in FIGS. 10 and 18, the middle position in the left-right direction is lowered, and the shape is raised to a shape at the positions of the left and right ends (the cross section is substantially V-shaped, for example). That is, when the upper opening 54 of the container main body A is closed with the lid B, the widened surface portions 4a, 4b, 4c, 4d face the upper end flat surface portions (ridge line portions) 50a, 50b, 50c, 50d of the container main body A. Therefore, the widened surface portions 4a, 4b, 4c, and 4d are formed into a shape (for example, substantially V shape) in which the middle position in the left-right direction is lowered and raised at the left and right ends. Has been. When the lid is closed, the widened surface portions 4a, 4b, 4c, and 4d of the lid B are positioned to face the upper flat surface portions (ridge line portions) 50a, 50b, 50c, and 50d of the container body A, but the lid A predetermined dimension is provided between the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d of the body B and the upper flat surface portions (ridge line portions) 50a, 50b, 50c, 50d of the container body A. For example, the container main body A and the lid B are configured such that a gap of about 0.7 to 3 mm (about 0.7 mm at the closest point and about 2 to 3 mm at the farthest point) exists. That is, since the lid body B is a lid, the lid body B abuts (hangs) on the container body A at some point (for example, a location near the lower end of the corners of the four corners) when the lid is closed. However, in the container of the present embodiment, the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d of the lid B are not in contact with the container body A (see FIG. 3). ). And it does not just say that it does not contact | abut, but it has separated so that the distance more than a predetermined dimension (for example, 0.5 mm) may be maintained. This is because when the water droplets adhering to the inner surfaces of the upper side surfaces 3a, 3b, 3c, 3d of the lid B fall downward along the inner surface, the widened surface portions 4a, 4b, 4c, This is to effectively prevent water droplets from entering the gaps between 4d and the upper flat surface portions (ridge line portions) 50a, 50b, 50c, 50d of the container main body A due to capillary action. That is, if the gaps between the widened surface portions 4a, 4b, 4c, 4d of the lid body B and the upper end flat surface portions (ridge line portions) 50a, 50b, 50c, 50d of the container body A are small, the upper side surface portions 3a, 3b, Although the water droplets that have fallen on the boundary lines between 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d are likely to enter the gap due to capillary action, the widened surface portions 4a, 4b, 4c, 4d of the lid B are provided. If the gaps between the upper flat surface portions (ridge line portions) 50a, 50b, 50c, and 50d of the container main body A are large as described above, water droplets are difficult to enter the gap. Accordingly, the gaps between the widened surface portions 4a, 4b, 4c, 4d of the lid B and the upper flat surface portions (ridge line portions) 50a, 50b, 50c, 50d of the container main body A are preferably as described above. . Water droplets that have fallen to the boundary lines (substantially V-shaped lines) with the widened surface portions 4a, 4b, 4c, 4d from the upper side to the lower side along the inner surfaces of the upper side surface portions 3a, 3b, 3c, 3d, Since the widened surface portions 4a, 4b, 4c, and 4d are surfaces that are spread outward in the horizontal direction, no further downward falls at that point. Instead, since the boundary lines between the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d are configured in a substantially V shape as described above, the middle from the left and right locations. It comes to slide down to the position. That is, the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b are arranged such that water droplets are collected at the lowest position (substantially middle position in the left-right direction) of the upper side surface portions 3a, 3b, 3c, 3d. , 4c and 4d are formed.

上記水滴が左右から集まって来るように構成された箇所（真中位置）には、水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄが設けられている。この水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄは、側壁面が内側に押し遣られ、かつ、下端部が上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界ラインよりも下側に突出しているように押し遣られた形状に成形されている。すなわち、この水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄ（側面部２）を正面から眺めた場合、水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄは、その上側が底辺となる二等辺三角形状（上端部における左右方向の長さ（横幅）ｍ_１が５〜２０ｍｍ程度。下端部における左右方向の長さ（横幅）ｍ_２が５ｍｍ以下（例えば、０．５〜３ｍｍ）程度。上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界位置（境界ライン）における左右方向の長さ（横幅）ｍ_３が５ｍｍ以下（例えば、０．５〜３ｍｍ）程度。上下方向の長さが７〜２０ｍｍ程度。左斜辺は、下側に行くにつれて連続的に右側に移る。右斜辺は、下側に行くにつれて連続的に左側に移る。）に成形されている。又、水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄは、上側面部３ａ，３ｂ，３ｃ，３ｄに対して垂直な面での断面が、図２からも判る通り、略レ字形状に成形されている。すなわち、上側面部３ａ，３ｂ，３ｃ，３ｄに対して垂直な方向における水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄの幅（縦幅）寸法が下端側ほど小さなものとなるよう成形されている。例えば、上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの境界位置（境界ライン）における水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄの幅（縦幅）寸法ｎ_１は１〜５ｍｍ程度、下端（先端）における水滴落下誘導用凸部６ａ，６ｂ，６ｃ，６ｄの幅（縦幅）寸法ｎ_２は２ｍｍ程度以下、ｎ_２＜ｎ_１であるように成形されている。 Water droplet drop guiding convex portions 6a, 6b, 6c and 6d are provided at locations (middle positions) where the water droplets are collected from the left and right. The projections 6a, 6b, 6c, 6d for dropping the water droplets have the side wall surfaces pushed inward, and the lower end portions are the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d. It is formed into a pushed shape so as to protrude below the boundary line. That is, when the water drop drop-inducing convex portions 6a, 6b, 6c, 6d (side surface portion 2) are viewed from the front, the water drop drop-inducing convex portions 6a, 6b, 6c, 6d have two bottoms. Equilateral triangle shape (left-right length (width) m ₁ at the upper end is about 5 to 20 mm. Left-right length (width) m ₂ at the lower end is about 5 mm or less (for example, 0.5 to 3 mm). The length (lateral width) m3 in the left-right direction at the boundary position (boundary line) between the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d is 5 mm or less (for example, 0.5 to ₃ mm) The length of the vertical direction is about 7 to 20 mm.The left oblique side is continuously moved to the right side as it goes down.The right oblique side is continuously moved to the left side as it goes down.) ing. Further, the projections 6a, 6b, 6c and 6d for inducing the drop of water droplets have a substantially letter-shaped cross section in a plane perpendicular to the upper side surface parts 3a, 3b, 3c and 3d, as can be seen from FIG. Molded. That is, the width (vertical width) of the water droplet drop guiding convex portions 6a, 6b, 6c, 6d in the direction perpendicular to the upper side surface portions 3a, 3b, 3c, 3d is formed to be smaller toward the lower end side. ing. For example, the width (vertical width) of the water droplet drop guiding convex portions 6a, 6b, 6c, 6d at the boundary positions (boundary lines) between the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d. dimensions _{n 1} is about 1 to 5 mm, the lower end (tip) of the water droplet dropping guiding protrusions 6a, 6b, 6c, 6d of the width (vertical width) dimension _{n 2} is less about 2 _mm, such that n 2 _{<n 1} Molded.

そして、凸部６ａ，６ｂ，６ｃ，６ｄ及びその周辺位置での形状を上記のような構成のものとしたから、凸部６ａ，６ｂ，６ｃ，６ｄの隣接位置まで到達して来た水滴は効果的に容器本体Ａ内に誘導落下する。すなわち、図１０に示される通り、上側面部３ａ，３ｂ，３ｃ，３ｄと拡幅面部４ａ，４ｂ，４ｃ，４ｄとの略Ｖ形状の境界ラインに誘導されて（境界ラインに沿って）凸部６ａ，６ｂ，６ｃ，６ｄの隣接位置まで到達して来た水滴は、凸部６ａ，６ｂ，６ｃ，６ｄの左右のラインに沿って下側に移行するや否やの時点で合体（凸部６ａ，６ｂ，６ｃ，６ｄの両側を伝わって来た水滴が合体）する。そして、合体した水滴は、合体によって重みが増すことから、凸部６ａ，６ｂ，６ｃ，６ｄの幅狭な下端から離脱・落下し、容器本体Ａで受け止められる。 And since the shape in the convex parts 6a, 6b, 6c, 6d and its peripheral position is configured as described above, the water droplets that have reached the adjacent positions of the convex parts 6a, 6b, 6c, 6d are It is effectively guided and dropped into the container body A. That is, as shown in FIG. 10, the convex portion is guided (along the boundary line) by a substantially V-shaped boundary line between the upper side surface portions 3a, 3b, 3c, 3d and the widened surface portions 4a, 4b, 4c, 4d. Water droplets that have reached the position adjacent to 6a, 6b, 6c, 6d are merged as soon as they move downward along the left and right lines of the convex portions 6a, 6b, 6c, 6d (convex portion 6a). , 6b, 6c, 6d, the water droplets that have traveled on both sides merge. The combined water droplets are increased in weight due to the combination, so that they drop and fall from the narrow lower ends of the convex portions 6a, 6b, 6c, 6d and are received by the container body A.

これに対して、凸部が上記した凸部６ａ，６ｂ，６ｃ，６ｄの如きの形状では無く、かつ、凸部近傍における蓋体の上側面部と拡幅面部との境界ラインが傾斜してない略水平な場合、又、蓋体の拡幅面部と容器本体の上端平坦面部（稜線部）とが接しているか離れていても離間寸法が小さい場合、即ち、図１１に示される如くの形状である場合、水滴誘導落下の機能が奏されないものであった。つまり、上側面部と拡幅面部との境界ラインが全般的には略円弧状のものであって左右の側から真中の方向に水滴が移動して来るようになっていても、凸部１１の近傍で境界ラインが略水平なものになっていると、水滴が凸部１１の位置まで移動して来るには長時間を要する。そして、拡幅面部と容器本体との間の隙間が小さいと、上側面部と拡幅面部との境界ラインに沿っての移動の間に水滴は毛細管現象によって拡幅面部と容器本体との間の隙間に嵌まり込み、その位置で水滴は貼り付いた如きのものになる。その結果、その位置に水滴が保持されてしまい、蓋を開けた際に水滴が弾けるように飛散するものであった。又、凸部１１と凸部１１の下端中央部に臍の如くに設けられた凸部１１ａとの横幅寸法が、連続的に変化した形状では無く、図１１に示される如く、上側面部と拡幅面部との境界ラインにおいて不連続的に変化したものになっていると、例えば点Ｘと点Ｙとの間の距離が５ｍｍ程度も有ると、点Ｘの位置まで誘導されて来た水滴は点Ｙの位置にまでは移動し難く、その結果、凸部１１ａの下端から水滴が誘導・落下され難いものであった。 On the other hand, the convex portion is not shaped like the convex portions 6a, 6b, 6c and 6d described above, and the boundary line between the upper side surface portion and the widened surface portion in the vicinity of the convex portion is not inclined. When it is substantially horizontal, or when the distance between the widened surface portion of the lid and the upper flat surface portion (ridge line portion) of the container body is in contact with or away from each other, the distance is small, that is, as shown in FIG. In this case, the function of water drop induced fall was not achieved. That is, even if the boundary line between the upper side surface portion and the widened surface portion is generally arc-shaped and water droplets move in the middle direction from the left and right sides, If the boundary line is substantially horizontal in the vicinity, it takes a long time for the water droplet to move to the position of the convex portion 11. If the gap between the widened surface portion and the container main body is small, water droplets move into the gap between the widened surface portion and the container main body by capillary action during the movement along the boundary line between the upper side surface portion and the widened surface portion. It fits in, and the water drops become stuck at that position. As a result, the water droplet was held at that position, and the water droplet was scattered so as to be flipped when the lid was opened. Further, the lateral width dimension of the convex portion 11 and the convex portion 11a provided like a navel at the center of the lower end of the convex portion 11 is not a continuously changing shape, but as shown in FIG. If the boundary line with the widened surface portion changes discontinuously, for example, if the distance between the point X and the point Y is about 5 mm, the water droplet guided to the position of the point X will be It was difficult to move to the position of the point Y, and as a result, water droplets were difficult to be guided and dropped from the lower end of the convex portion 11a.
