201116461 六、發明說明： I：發明戶斤屬之技術領域3 發明領域 本發明係有關於用以填充飲料之瓶形狀容器，例如合 成樹脂製之瓶型容器。 【先前技4标】 發明背景 為了填充各種飲料，廣泛地使用瓶型容器，例如合成 樹脂製之瓶型容器。該等瓶型容器之橫截面為了容易收納 或搬運至冰箱等，大多為矩形。 瓶型容器存在其容量2公升左右之大型者。如此之大型 瓶型容器有時無法藉人的手充分地握持其本體部。因此， 近年來，為了容易握持瓶型容器，一般的作法是於容器之 本體部形成腰部，即形成朝周方向延伸之寬幅之溝。此外， 於專利文獻1揭示腰部之四個角部由朝瓶型容器内側彎曲 並且中央縱向之寬度比於上下方向延伸之2個弧狀更寬之 研缽狀曲線部構成。在此情形中，由於指叉部及手掌部份 地嵌入腰部，故更容易握持瓶型容器。 先前技術文獻 專利文獻 專利文獻1特開2008-296920號公報 【發明内容】 發明概要 發明欲解決之課題 3 201116461 但是，在將液體充滿於瓶型容器，特別是2公升用瓶型 容器中時，瓶型容器變成相當重。因此，拿起如此瓶型容 器時，人必須以非常強大之力量握持瓶型容器之本體部， 但是，當以非常強大之力量握持本體部時，人之手有時會 相對本體部滑動，結果，指之前端由腰部滑出，瓶型容器 全體由人之手滑落。特別地，由口部取下蓋時發展成瓶 型谷裔之液體由口部流出之情況。 即使在使用揭示於專利文獻i之瓶型容器時，雖然指又 部及手掌卡合連接於瓶型容器之腰部，但是指之前端亦會 由腰部滑出，無法握持瓶型容ϋ。如此，特別在瓶型容器 重時’有由於指之前端由腰部滑出，難以拿起瓶型容器之 問題。 本發明係有鐘於如此情事作成者，且目的在於提供一 種即使瓶型容器重時，指之前端亦不會由腰部滑出，可適 切拿起之瓶型容器。 用 以欲解決課題之手段

體圖，第2圖是第1圖所示之實施型態之瓶型容器的正面 圖。該等圖式所示之瓶型容器10由合成樹脂，例如聚對苯 201116461 二甲酸乙二醋形成’為大約2公升之容量。瓶型容 塑成形預成形體，雙軸延伸形成。因此，依據本發明，^ 型容器10之厚度相當小。 如第1圖及第2圖所示，瓶型容器1〇主要由填充飲料等 液體之口部11、橫截面大略矩形狀之本體部12、連結口部 11與本體部12之肩部13、及在與口部n相反侧上關閉本體 部12之底部構成。又，於口部1丨可安裝蓋，但為達簡潔之 目的，省略圖示蓋。 第3圖是第1圖所示之瓶型容器的底面圖。在底部中， 環繞瓶型容器10之中心線C0形成圓形凹孔18。而且，多數 底部溝14a由圓形凹孔18放射狀地延伸到瓶型容写1 〇之外 周面（參照第2圖）。該等圓形凹孔18及底部溝14a達成補強瓶 型容器10之底部14的目的。 如第1圖及第2圖所示，朝本體部12之周方向延伸之腰 部15形成於本體部12之縱方向中心位置。如第2圖所示，腰 部15呈寬幅溝之形態，且由從本體部上方部份4〇延伸之上 側傾斜面15a、從本體部下方部份45延伸之下側傾斜面 15b、及連接該等上側傾斜面15a與下側傾斜面Hb之溝底面 15c構成。藉如此之腰部15，本體部12分成本體部上方部份 40與本體部下方部份45。 第4圖是沿第2圖所示之瓶型容器之線B_B觀看的橫截 面圖。如第4圖所示，包含腰部15之溝底面15c之區域的橫 載面形狀亦為大略矩形狀。 第5圖是本實施型態之瓶型容器的部份放大圖。如由第 201116461 5圖可知’該等上側傾斜面15a及下侧傾斜面丨5b之上緣及下 緣分別朝水平方向延伸。又’腰部15之溝底面i5c相對於瓶 型容器10之底面為垂直。 腰部15全體之縱向之高度為41.9mm，僅腰部15之溝底 面15c之縱向高度為7mm。因此，使人的大拇指及與其對向 之四指’例如食指、中指、無名指或小指，及該等指叉和 相關之手掌的部份密接於腰部15。又，如圖所示，腰部i5 之下側傾斜面15b比上側傾斜面15a大許多，且下側傾斜面 15b向外側由凸狀之曲面構成。 此外，如由第5圖可知，瓶型容器1〇之正面側中，腰部 15之區域形成有凹部20。凹部20，如由第4圖可知，亦互相 對向形成於瓶型容器10之背面側。又，凹部2〇亦可鄰接於 腰部15形成於上方或下方。 在第5圖中，凹部20之上端及下端分別在瓶型容器1〇之 縱向上越過溝底面15c，部份地延伸到上側傾斜面15a及下 側傾斜面15b。又，凹部20之緣部由形成於上側傾斜面15a 之上緣部21、形成於下側傾斜面15b之下緣部23、及橫跨溝 底面15c全體於縱向上形成之中間緣部22構成。 又，如第5圖所示，凹部20具有平坦之凹部底面％，凹 部底面26由在橫方向延伸之長方形，及具有與該長方形下 側長邊共用之上底之向下等腰梯形構成。如由第5圖可知， 凹。卩底面26專之等腰梯形部份進入溝底面15c之區域。又， 凹部底面26可為與第5圖所示之形狀不同之形狀，但最好大 到足以收容人手指之第一關節。 201116461 在第5圖中’凹部20之下緣部23向下方彎曲成凸狀。而 且’如由第5圖可知’下緣部23比上緣部21大很多，纟士果， 下緣部23之曲率半徑比上緣部21之曲率半徑小很多。由於 下緣部23呈如此之形狀’人之手指由本體部12之外面通過 下緣部23，可輕易地被收容於凹部20。 如由第4圖及第5圖可知，凹部20之下緣部。藉互相鄰 接之第一及第二C字形狀曲面幻、34連結於凹部底面％。由 下緣部23延伸之第一C字形狀曲面33之兩端部連結於連於 中間緣部22與凹部底面26之傾斜面32 ’鄰接於四部底面％ 之第二C字形狀曲面34未連結於傾斜面32。又，第二c字开》 狀曲面34具有於橫方向部份地延伸之2個肋部35、％。夢今 等肋部35、36可於橫方向補強瓶型容器10之凹部2〇。此外， 該等肋部35、36達成相對於人之手指止滑之目的。 凹部2〇之上緣部21藉上面31連結於凹部底面％，在第$ 圖中’凹部20之上緣部21及上面31向上方彎曲成凸狀。上 緣部21及上面31等相對腰部15大致平行延伸時當拿起瓶 型奋态10時，人之手指可能會陷入上緣部21及上面31等。 相對於此，在上緣部21及上面31向上方彎曲成凸狀之本發 中’人之手指不會陷入上緣部21及上面31。 第5圖 叫且，如由 • α ’凹部20之橫方向中央部最向上方彎曲成凸狀 第5圖中之凹部2〇以後述之凹部之橫方向距離為弦之長 ^描晝成圓弧狀，但只要凹部20之橫方向中央部成為最 ，則其中央部以外處亦可包含成為直線狀之部份。 圖疋沿苐2圖所示之實施型態之瓶型容器之線a a 9 201116461 觀看的縱戴面圖，弟7圖是第6圖所示之凹部之縱截面圖。 特別地’如由第7圖可知，上面31在凹部底面％之附近，向 瓶型容器10之内側彎曲成凸狀。上面31可由至少一個曲面 形成，且亦可由多數平坦面形成。 由於凹部20為如此之形狀及尺寸，故人之手指握持拿 起瓶型容器10時，收容於凹部2〇之手指前端變成扣在上面 31與凹部底面26之間的彎曲部份上。因此，即使填充飲料， 瓶型容器10為重時，手指前端亦不容易由凹部2〇滑出。因 此’在本發明中，可簡單地拿起瓶型容器1〇。 此外’由於一對凹部2〇互相對向地形成，故可將不同 之手指’例如大拇指及中指插入各個凹部2〇。因此，在本 實施型態中’可容易且確實地握持瓶型容器1〇。 而且’在本實施型態中，凹部20之深度(相當於腰部15 與凹部底面2 6間之相對於凹部底面2 6垂直之距離）比較 深。凹部20之各個深度01為5〇1111至7mm，最好為6mm。深 度D1小於5mm時，手指之前端變成難以扣在上面31與凹部 底面26間之彎曲部份上。另一方面，深度D1大於7mm時， 手指之前端難以到達上面31與凹部底面26間之彎曲部份。 又，凹部20之橫方向距離D3為54mm至62mm，最好為58mm。 由於凹部20為如此之尺寸，故握持瓶型容器10時，人 之大拇指或中指中之至少一者之第一關節被充分地收容於 凹部20。此外，藉人之大拇指及中指推壓凹部20之各個凹 部底面26時，大拇指或中指中之至少一者之中心軸線變成 在凹部20内中比本體部12之外面更位於内侧。結果，可將 10 201116461 大拇指或中指確實地扣在凹部2〇之上面31。 又，令包含腰部15之溝底面15c之區域之橫截面之短邊 間的距離為D2時’距離D2為67mm至74mm ’最好為71如如 人在手之大拇指及大拇指以外之手指自然地打開的狀態 下’握持物時’大多感到容易握持該物。因此，當距離〇2 小於67mm時，由於感到以狹小寬度不易握持，在手指前端 施加強大力量，故當瓶型容器1〇之蓋被取下時，容易使瓶 型谷器10内之液體由口部11流出。另一方面，當距離大 於74mm時’感到以大寬度不易握持，同樣地容易使瓶型容 器10内之液體由口部11流出。而且，2個凹部之合計、、果声 (D1+D2)對距離D2之比為大約0.16，該比最好為〇 13至 0·20。在如此情形下’可更適切地握持瓶型容器1〇 ^ 此外，如參照第4圖可知，瓶型容器1〇之本體部下方部 份45之橫截面呈大略矩形狀，其四個角部19形成為圓狐， 本體部上方部份40之檢截面亦相同。在本發明中，包人 部15之溝底面15c之區域之橫截面亦呈同樣之大略矩形 狀，其四個角部16亦形成為圓弧。 第8圖是第1圖所示之實施型態之瓶型容器的側面圖。 在第8圖中’人為了握持瓶型容器1〇時，人之2個手指，例 如大拇指及中指，朝第8圖之紙面的貫通方向插入腰部^之 互相對向部份。在本實施型態中’腰部15之縱向之尺寸為 41.9mm且比較大，又，腰部15形成於本體部之外周面三 體，此外，參照第5圖，如前所述，腰部15為包含上側傾斜 面15a及下側傾斜面15b之構造。因此，上侧傾斜面15a及下 11 S- 201116461 側傾斜面15b達成可說是引導的目的，前述人之2個手指被 引導至溝底面15c之外周。 又’在第4圖中，顯示通過本體部12之橫截面之2個長 邊之中心的線A1。該線A1與互相連接對向之2個凹部20中 心的線是共通的。配置於線A1上之2個點Cl、C2位於溝底 面15c之周方向延長線與線Ai的交點。如第4圖所示，由其 中一點C1通過溝底面15c之延長線與溝底面15c之一部份延 伸至另一點C2之周方向距離j)4為140mm至165mm，最好為 150mm至156mm。該周方向距離D4比140mm短時，手指長 的人握持瓶型容器10時，手指之前端將會越過凹部2〇。又， 周方向距離D4比165mm長時，手指短的人握持瓶型容器10 時’手指之前端無法到達凹部20之上面31的彎曲部。相對 於此’周方向距離D4在140mm至165mm之範圍時，不論是 手指長之人或手指短之人，均可容易地握持瓿型容器10。 又’當由大拇指及食指側觀看人的手時，人的手通常 呈大略C字形狀。距離D2尺寸被決定成使人的手不需要將 手指過度地張開。由於容器10之腰部15之溝底面15c之四個 角部16之曲率半徑比較大，所以容器10符合大略C字形之人 的手。因此，握持瓶型容器10時，人不需過度地張開手指。 此外，腰部15之溝底面15c之四個角部16之曲率半徑為 24mm至34mm，最好為28mm至30mm。 人之2個手指插入腰部15時，人之2個手指，例如大拇 指及中指，該等指叉及相關之手掌的部份正好適合腰部15 及上側傾斜面15a。藉此，人之手指前端可到達凹部20之上 12 201116461 面31之彎曲部。因此，如果由此狀態，使人的手上升，則 瓶型容器10被人之2個手指，例如大拇指及中指’該等指又 及相關之手掌的部份支持。因此，拿起瓶型容器1〇時，不 需要以強大力量握持瓶型容器10。因此，可容易地拿起瓶 型容器10。 此外，由於在手指之前端不需要施加強大力量，故例 如，即使取下瓶型容器10之蓋時，瓶型容器1〇内之液體亦 不會由口部11流出。因此，可穩定拿起、搬運瓶型容器丨〇。 在此，參照第1圖、第2圖及第6圖時’本體部12之本體 部上方部份4〇形成有於周方向延伸之多數溝41，本體部下 方部份45形成有於周方向延伸之多數溝牝。該等溝Μ、仆 達成於瓶型容器10施加縱向力時，使瓶型容器1〇之本體部 12於縱向彈性變形之目的。 通常，為了在本體部上方部份4〇貼上商品標籤（圖未 示）’以良好地看見商品標籤（圖未示），在本體部上方部份 40之溝41設置縱肋等時，僅使本體部12之本體部下方部份 45彈性變形。 又，如第6圖所示，肩部13與本體部12間之區域乂丨由圓 弧形成，形成於本體部下方部份45之溝46與本體部下方部 份4 5之間的區域X 3亦同樣地由圓弧形成。此外，第6圖中顯 示於本體部下方部份45中由上方算起位於第二個之溝仂作 為區域Χ3之代表，但本體部下方部份45中之其他溝私亦為 同樣者。又，如再參照第5圖可知，腰部15之下側傾斜面i5b 與本體部下方部份4 5之間的區域χ 2亦由圓弧形成。 13 S- 201116461 如由第6圖可知’在區域XI中，由側面看瓶型容器10 之曲率半徑R1比較大，但是比肩部13本身之曲率半徑小。 相同地’如由第2圖可知，在區域XI中，由正面觀看瓶型容 器10之曲率半徑R1'亦比較大，但是比肩部13之曲率半徑 小。此外’曲率半徑R1亦比區域χ3中之曲率半徑尺3小，但 是比區域X2中之曲率半徑R2小。又，如比較第5圖與第6圖 可知’區域X2中之曲率半徑R2比區域χ3中之曲率半徑r3 大。再者，由側面觀看之曲率半徑，最好是 R16至R20。由正面觀看之曲率半徑幻，是尺⑺至尺％，最好 是R14至R18。該等曲率半徑R1、R1，大於前述值時，於縱 向施加力量至瓶型容器10時，瓶型容器1〇之肩部13將輕易 地塑性變形。 如前所述，瓶型容器10於其搬送時袈滿瓦榜紙箱（圖未 示），再依序堆起多數瓦楞紙箱。此時，於縱向施加非常強 大之力量至各個瓶型容器10。 在本實施型態中’曲率半徑R1、R1，比曲率半徑R2、 R3大，但是比肩部13本身之曲率半徑小很多，因此，可說 是肩部13成為接近容器1〇之軸線方向立起之狀態。即，在 本實施型態中，由於使曲率半徑R1、R1,比肩部13之曲率半 徑小，故肩部13相對於水平面之角度變大。因此，即於縱 向施加非常強大之力量至瓶型容器10眸，你圳… 吁，瓶型容器10之肩 部13及腰部15亦幾乎料形，所施^力大部份筆直地傳 至本體部下方部份45。因此，在本實施型態中，當施加縱 向力時，瓶型容器10之比腰部15更位於上方之部产大克均 201116461 等地沈降，本體部下方部份45主要地彈性變形。即，在本 實施型態中，即使於縱向施加力至瓶型容器10，肩部13及/ 或腰部15亦不會朝斜方向彎曲。因此，可防止肩部13及/或 腰部15因塑性變形而破損。 又，特別地，如由第1圖等可知，瓶型容器10之肩部13 橫跨其周方向全體是平滑的，未形成隆起部等。因此，即 使於瓶型容器10施加縱向之力時，亦不會有應力集中於如 此之隆起部。因此，亦沒有如此隆起部塑性變形。因此， 在本實施型態中，可防止瓶型容器10之肩部13塑性變形。 此外，在本實施型態中，以瓶型容器10為由合成樹脂 形成者說明，但是，瓶型容器10亦可由其他材料，例如玻 璃形成。 I：圖式簡單說明3 第1圖是依據本發明之一個實施型態之瓶型容器的立 體圖。 第2圖是第1圖所示之實施型態之瓶型容器的正面圖。 第3圖是第1圖所示之實施型態之瓶型容器的底面圖。

Description of the Invention: I: Technical Field of Inventions 3 Field of the Invention The present invention relates to a bottle-shaped container for filling a beverage, for example, a bottle-shaped container made of synthetic resin. BACKGROUND OF THE INVENTION In order to fill various beverages, bottle type containers such as synthetic resin bottle type containers are widely used. The cross-section of the bottle-shaped containers is mostly rectangular in order to be easily stored or transported to a refrigerator or the like. The bottle type container has a large size of about 2 liters. Such a large bottle type container sometimes cannot hold the body portion sufficiently by a human hand. Therefore, in recent years, in order to easily hold the bottle type container, it is common practice to form a waist portion in the body portion of the container, i.e., to form a wide groove extending in the circumferential direction. Further, Patent Document 1 discloses that the four corner portions of the waist portion are formed by a mortar-shaped curved portion which is curved toward the inside of the bottle-shaped container and whose width in the center longitudinal direction is wider than two arc-shaped extending in the vertical direction. In this case, since the finger portion and the palm portion are partially embedded in the waist, it is easier to hold the bottle type container. CITATION LIST Patent Literature PTL No. 2008-296920 SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION 3 201116461 However, when a liquid is filled in a bottle type container, particularly a 2 liter bottle type container, The bottle type container becomes quite heavy. Therefore, when picking up such a bottle type container, the person must hold the body portion of the bottle type container with a very strong force, but when the body portion is held with a very strong force, the human hand sometimes slides relative to the body portion. As a result, the front end is slid out from the waist, and the entire bottle-shaped container is slid by the hand of the person. In particular, when the cap is removed from the mouth, the liquid of the bottle-type gull is developed to flow out from the mouth. Even when the bottle type container disclosed in the patent document i is used, although the finger and the palm are snap-fitted to the waist of the bottle type container, the front end is also slid out of the waist portion, and the bottle type container cannot be held. Thus, especially when the bottle type container is heavy, there is a problem that it is difficult to pick up the bottle type container because the front end is slipped out from the waist. The present invention is made in such a manner, and aims to provide a bottle type container which can be appropriately picked up even if the bottle type container is heavy, and the front end is not slipped out from the waist. In order to achieve the above object, according to the first aspect of the invention, there is provided a bottle type container, a body portion, a shoulder portion for connecting the mouth portion and the body portion, and a body portion for closing the body portion. The bottom of the lower end and the entire circumference of the main body portion = the waist portion 'including at least one concave portion formed above or below the waist portion or the curved waist region, and the upper portion of the concave portion is curved upwardly. A portion of the longitudinal cross-sectional shape of the upper surface of the concave portion is curved into a convex shape toward the inside of the bottle-shaped container. ^P In the first invention towel, the front end of the finger received in the recess is fastened to the top of the recess 201116461. Therefore, even if the bottle type container is heavy even when the beverage is filled, it means that the front end is not easily slipped out of the concave portion of the container. Therefore, the container can be simply picked up. According to the second aspect of the invention, in the first aspect of the invention, the two concave portions that face each other are formed. That is, in the second aspect of the invention, since the two concave portions are opposed to each other, different fingers can be inserted into the respective concave portions. Therefore, the bottle type container can be easily and surely held. According to a third aspect of the invention, in the second aspect of the invention, the recessed portion has a sufficient size for accommodating the first joint of at least one of the thumb and the middle finger when the bottle type container is held. That is, in the third invention, the finger can be surely fastened to the upper surface of the concave portion. According to a fourth aspect of the invention, in the first aspect of the invention, the recessed portion (eighth) of the middle portion of the thumb or the middle finger is at least one of the center portion of the thumb or the middle finger. In the fourth aspect of the invention, in the fourth aspect of the invention, the above-mentioned upper surface of the concave portion is at least a sufficient depth. A curved surface or a plurality of flat surfaces. In the fifth invention, the upper surface of the concave portion can be easily formed. Further, when the upper surface of the concave portion 4 is composed of a plurality of flat surfaces, the bottle type container can be reinforced. According to the sixth invention In any one of the first to fifth aspects, the waist portion includes an upper and lower inclined portion inclined from the main body portion _ side, and a bottom surface of the two inclined 敎 grooves, the cross section of the groove bottom surface being slightly rectangular In the sixth invention, a bottle-shaped container having a more suitable structure is provided in the sixth aspect of the present invention.

I: Embodiment: J DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following drawings, the same reference numerals are given to the same members. For the sake of easy understanding, the scales are appropriately changed. 1 is a perspective view of a bottle type container according to an embodiment of the present invention, and FIG. 2 is the first drawing. A front view of the bottle container of the embodiment shown. The bottle container 10 shown in the drawings is formed of a synthetic resin such as polyparaphenyl 201116461 ethylene diacetate to form a capacity of about 2 liters. The preformed body is formed by biaxial stretching. Therefore, according to the present invention, the thickness of the container 10 is relatively small. As shown in Figs. 1 and 2, the bottle type container 1 is mainly filled with a liquid such as a beverage. The mouth portion 11, the main body portion 12 having a substantially rectangular cross section, the joint portion 11 and the shoulder portion 13 of the main body portion 12, and the bottom portion of the main body portion 12 on the side opposite to the mouth portion n are formed. The cover can be attached, but the cover is omitted for the sake of brevity. Fig. 3 is a bottom view of the bottle container shown in Fig. 1. In the bottom, a circular recess 18 is formed around the center line C0 of the vial container 10. Further, the plurality of bottom grooves 14a are radially extended from the circular recessed holes 18 to the outer surface of the bottle type 1 (refer to Fig. 2). The circular recessed holes 18 and the bottom groove 14a serve the purpose of reinforcing the bottom portion 14 of the bottle-shaped container 10. As shown in Figs. 1 and 2, the waist portion 15 extending in the circumferential direction of the main body portion 12 is formed at the center in the longitudinal direction of the main body portion 12. As shown in Fig. 2, the waist portion 15 is in the form of a wide groove, and extends from the upper portion 4b of the main body portion to the upper side inclined surface 15a, the lower portion of the main body portion 45, and the lower side inclined surface 15b, and the connection. The upper inclined surface 15a and the lower bottom inclined surface Hb are formed by the groove bottom surface 15c. With such a waist portion 15, the body portion 12 is divided into an upper portion 40 of the body portion and a lower portion 45 of the body portion. Fig. 4 is a cross-sectional view taken along line B_B of the bottle type container shown in Fig. 2. As shown in Fig. 4, the cross-sectional shape of the region including the groove bottom surface 15c of the waist portion 15 is also substantially rectangular. Fig. 5 is a partially enlarged view of the bottle type container of the present embodiment. As can be seen from the figure of 201116461 5, the upper and lower edges of the upper inclined surface 15a and the lower inclined surface 丨5b respectively extend in the horizontal direction. Further, the bottom surface i5c of the waist portion 15 is perpendicular to the bottom surface of the bottle container 10. The longitudinal height of the entire waist portion 15 is 41.9 mm, and only the longitudinal height of the groove bottom surface 15c of the waist portion 15 is 7 mm. Therefore, the thumb and the four fingers opposite thereto, such as the index finger, the middle finger, the ring finger or the little finger, and the portions of the finger and the associated palm are in close contact with the waist portion 15. Further, as shown in the figure, the lower side inclined surface 15b of the waist portion i5 is much larger than the upper side inclined surface 15a, and the lower inclined surface 15b is formed outward by a convex curved surface. Further, as is apparent from Fig. 5, in the front side of the bottle-shaped container 1A, the recessed portion 20 is formed in the region of the waist portion 15. As can be seen from Fig. 4, the recesses 20 are also formed on the back side of the bottle container 10 so as to oppose each other. Further, the recess 2' may be formed above or below the waist portion 15. In Fig. 5, the upper end and the lower end of the recessed portion 20 respectively extend over the groove bottom surface 15c in the longitudinal direction of the bottle-shaped container 1 and partially extend to the upper inclined surface 15a and the lower inclined surface 15b. Further, the edge portion of the recessed portion 20 is formed by the upper edge portion 21 formed on the upper inclined surface 15a, the lower edge portion 23 formed on the lower inclined surface 15b, and the intermediate edge portion 22 formed in the longitudinal direction across the groove bottom surface 15c. . Further, as shown in Fig. 5, the concave portion 20 has a flat bottom portion % of the concave portion, and the concave bottom surface 26 is formed of a rectangular shape extending in the lateral direction and a downward isosceles trapezoid having a bottom portion shared with the long side of the rectangular lower side. As can be seen from Fig. 5, it is concave. The bottom surface of the crucible 26 is specifically formed in the region of the bottom surface 15c of the groove. Further, the concave bottom surface 26 may have a shape different from that shown in Fig. 5, but is preferably large enough to accommodate the first joint of a human finger. 201116461 In Fig. 5, the lower edge portion 23 of the recess 20 is curved downward in a convex shape. Further, as can be seen from Fig. 5, the lower edge portion 23 is much larger than the upper edge portion 21, and the curvature radius of the lower edge portion 23 is much smaller than the radius of curvature of the upper edge portion 21. Since the lower edge portion 23 has such a shape that the human finger passes through the lower edge portion 23 from the outer surface of the main body portion 12, it can be easily accommodated in the concave portion 20. As can be seen from FIGS. 4 and 5, the lower edge portion of the recess 20 is formed. The first and second C-shaped surfaces are adjacent to each other, and 34 is connected to the bottom surface of the recess. Both end portions of the first C-shaped curved surface 33 extending from the lower edge portion 23 are connected to the inclined surface 32' connected to the intermediate edge portion 22 and the concave portion bottom surface 26, and the second C-shaped curved surface 34 adjacent to the bottom portion of the four portions is not connected. On the inclined surface 32. Further, the second c-shaped curved surface 34 has two ribs 35 and % extending partially in the lateral direction. The ribs 35, 36 such as the dream can reinforce the recess 2 of the bottle container 10 in the lateral direction. In addition, the ribs 35, 36 achieve the purpose of slipping with respect to the fingers of a person. The upper edge portion 21 of the concave portion 2 is connected to the bottom surface % of the concave portion by the upper surface 31, and the upper edge portion 21 and the upper surface 31 of the concave portion 20 are curved upward in a convex shape in the Fig. When the upper edge portion 21 and the upper surface portion 31 and the like are substantially parallel with respect to the waist portion 15, when the bottle type is lifted, the human finger may fall into the upper edge portion 21 and the upper surface 31. On the other hand, in the present invention in which the upper edge portion 21 and the upper surface 31 are curved upward in a convex shape, the human finger does not fall into the upper edge portion 21 and the upper surface 31. In the fifth figure, the central portion of the lateral portion of the concave portion 20 is curved upward in the convex portion. The concave portion in the fifth figure is the length of the concave portion of the concave portion which will be described later. Although it is an arc shape, as long as the center part of the horizontal direction of the recessed part 20 becomes the largest, the part which is a linear part may be contained except the center part. Fig. 2 is a longitudinal sectional view of the concave portion shown in Fig. 6 taken along the line of the bottle type container of the embodiment shown in Fig. 2 a a 9 201116461. In particular, as can be seen from Fig. 7, the upper surface 31 is curved in a convex shape toward the inside of the bottle container 10 in the vicinity of the bottom surface % of the concave portion. The upper surface 31 may be formed of at least one curved surface and may also be formed of a plurality of flat surfaces. Since the recessed portion 20 has such a shape and size, when the human finger holds the bottle-shaped container 10, the front end of the finger received in the concave portion 2 turns into a curved portion which is fastened between the upper surface 31 and the bottom surface 26 of the concave portion. Therefore, even if the bottle-shaped container 10 is heavy when the beverage is filled, the tip end of the finger is not easily slid out by the concave portion 2〇. Therefore, in the present invention, the bottle type container 1 can be simply picked up. Further, since the pair of concave portions 2〇 are formed opposite to each other, different fingers such as a thumb and a middle finger can be inserted into the respective concave portions 2〇. Therefore, in the present embodiment, the bottle type container 1 can be easily and surely held. Further, in the present embodiment, the depth of the concave portion 20 (corresponding to the distance between the waist portion 15 and the bottom surface 26 of the concave portion perpendicular to the bottom surface 26 of the concave portion) is relatively deep. Each depth 01 of the recess 20 is 5 〇 1111 to 7 mm, preferably 6 mm. When the depth D1 is less than 5 mm, the front end of the finger becomes difficult to buckle on the curved portion between the upper surface 31 and the bottom surface 26 of the concave portion. On the other hand, when the depth D1 is larger than 7 mm, it is difficult for the front end of the finger to reach the curved portion between the upper surface 31 and the bottom surface 26 of the concave portion. Further, the lateral direction distance D3 of the concave portion 20 is 54 mm to 62 mm, preferably 58 mm. Since the recess 20 is of such a size, when the bottle container 10 is held, the first joint of at least one of the person's thumb or middle finger is sufficiently accommodated in the recess 20. Further, when the thumb and the middle finger of the person press the bottom surface 26 of each recess of the recess 20, the center axis of at least one of the thumb or the middle finger becomes more inside than the outer surface of the body portion 12 in the recess 20. As a result, the 10 201116461 thumb or middle finger can be securely fastened to the upper surface 31 of the recess 2 . Further, when the distance between the short sides of the cross section of the region including the groove bottom surface 15c of the waist portion 15 is D2, the distance D2 is 67 mm to 74 mm. It is preferably 71 as the finger of the hand and the thumb other than the thumb. In the state of being naturally opened, it is easy to hold the object when it is 'holding the object'. Therefore, when the distance 〇2 is less than 67 mm, since it is difficult to hold with a narrow width, a strong force is applied to the front end of the finger, so that when the lid of the bottle-shaped container 1 is removed, the liquid in the bottle-shaped sifter 10 is easily made. It flows out from the mouth portion 11. On the other hand, when the distance is larger than 74 mm, it is felt that it is difficult to hold with a large width, and similarly, the liquid in the bottle-shaped container 10 is easily discharged from the mouth portion 11. Further, the total of the two concave portions, the ratio of the fruit sound (D1 + D2) to the distance D2 is about 0.16, and the ratio is preferably 〇 13 to 0·20. In this case, the bottle container 1 can be held more appropriately. Further, as can be seen from Fig. 4, the lower portion 45 of the body portion of the bottle container 1 has a substantially rectangular cross section, and its four corners. The portion 19 is formed as a round fox, and the section 40 above the body portion is also the same. In the present invention, the cross section of the groove bottom surface 15c of the hull portion 15 is also substantially rectangular in shape, and the four corner portions 16 are also formed in a circular arc shape. Fig. 8 is a side view showing the bottle type container of the embodiment shown in Fig. 1. In Fig. 8, when a person holds a bottle container, two fingers of a person, such as a thumb and a middle finger, are inserted into the opposing portions of the waist portion in the direction of the paper surface of Fig. 8. In the present embodiment, the longitudinal dimension of the waist portion 15 is 41.9 mm and relatively large, and the waist portion 15 is formed on the outer peripheral surface of the main body portion. Further, referring to Fig. 5, as described above, the waist portion 15 is included. The structure of the upper inclined surface 15a and the lower inclined surface 15b. Therefore, the upper inclined surface 15a and the lower 11 S-201116461 side inclined surface 15b achieve the purpose of guiding, and the two fingers of the person are guided to the outer periphery of the groove bottom surface 15c. Further, in Fig. 4, a line A1 passing through the center of the two long sides of the cross section of the body portion 12 is shown. This line A1 is common to the lines connecting the centers of the two recesses 20 opposed to each other. The two points C1 and C2 disposed on the line A1 are located at the intersection of the extension of the circumferential direction of the groove bottom surface 15c and the line Ai. As shown in Fig. 4, the distance j) 4 from the one point C1 through the extension line of the groove bottom surface 15c and the groove bottom surface 15c to the other point C2 is 140 mm to 165 mm, preferably 150 mm to 156 mm. When the circumferential direction distance D4 is shorter than 140 mm, when the finger-length person holds the bottle-shaped container 10, the front end of the finger will pass over the concave portion 2〇. Further, when the circumferential direction distance D4 is longer than 165 mm, when the person with a short finger holds the bottle container 10, the front end of the finger cannot reach the curved portion of the upper surface 31 of the concave portion 20. When the circumferential distance D4 is in the range of 140 mm to 165 mm, the 瓿-shaped container 10 can be easily held by a person with a long finger or a short finger. Also, when the human hand is viewed from the side of the thumb and forefinger, the human hand is usually roughly C-shaped. The distance D2 size is determined such that the human hand does not need to open the finger excessively. Since the radius of curvature of the four corner portions 16 of the groove bottom surface 15c of the waist portion 15 of the container 10 is relatively large, the container 10 conforms to the hand of a person having a substantially C-shape. Therefore, when the bottle type container 10 is held, the person does not need to open the finger excessively. Further, the four corner portions 16 of the groove bottom surface 15c of the waist portion 15 have a radius of curvature of 24 mm to 34 mm, preferably 28 mm to 30 mm. When two fingers of the person are inserted into the waist 15, two fingers of the person, such as the big thumb and the middle finger, the portions of the fingers and the associated palms are just adapted to the waist 15 and the upper inclined surface 15a. Thereby, the front end of the finger of the person can reach the curved portion of the face 31 of the 201116461. Therefore, if the human hand is raised in this state, the bottle container 10 is supported by two fingers of the person, such as the thumb and the middle finger, the fingers and the related palm. Therefore, when the bottle type container is picked up, it is not necessary to hold the bottle type container 10 with a strong force. Therefore, the bottle container 10 can be easily picked up. Further, since it is not necessary to apply a strong force at the front end of the finger, for example, even if the lid of the bottle type container 10 is removed, the liquid in the bottle type container 1 does not flow out from the mouth portion 11. Therefore, it is possible to stably pick up and carry the bottle type container. Here, referring to FIG. 1, FIG. 2, and FIG. 6, the upper portion 4 of the main body portion of the main body portion 12 is formed with a plurality of grooves 41 extending in the circumferential direction, and the lower portion 45 of the main body portion is formed in the circumferential direction. Extend most of the gullies. These gullies and servants achieve the purpose of elastically deforming the body portion 12 of the bottle-shaped container 1 in the longitudinal direction when the longitudinal force is applied to the bottle-shaped container 10. Usually, in order to attach a product label (not shown) to the upper portion of the main body portion to clearly see the product label (not shown), when the vertical rib is provided in the groove 41 of the upper portion 40 of the main body portion, only The lower portion 45 of the body portion of the body portion 12 is elastically deformed. Further, as shown in Fig. 6, the region between the shoulder portion 13 and the main body portion 12 is formed by a circular arc, and is formed in a region X between the groove 46 of the lower portion 45 of the main body portion and the lower portion 45 of the main body portion. 3 is also formed by an arc. Further, in Fig. 6, the lower portion of the main body portion 45 is located at the second groove as the representative of the region Χ3, but the other portions of the lower portion 45 of the main body portion are also the same. Further, as will be further described with reference to Fig. 5, the region χ 2 between the lower inclined surface i5b of the waist portion 15 and the lower portion 45 of the body portion is also formed by a circular arc. 13 S-201116461 As can be seen from Fig. 6, in the region XI, the radius of curvature R1 of the bottle-shaped container 10 is relatively large when viewed from the side, but is smaller than the radius of curvature of the shoulder portion 13 itself. Similarly, as can be seen from Fig. 2, in the region XI, the radius of curvature R1' of the bottle-shaped container 10 viewed from the front is also relatively large, but is smaller than the radius of curvature of the shoulder portion 13. Further, the radius of curvature R1 is smaller than the radius of curvature rule 3 in the region χ3, but smaller than the radius of curvature R2 in the region X2. Further, as compared with Figs. 5 and 6, it can be seen that the radius of curvature R2 in the region X2 is larger than the radius of curvature r3 in the region χ3. Further, the radius of curvature viewed from the side is preferably R16 to R20. The radius of curvature of the front view is imaginary (7) to ft., preferably R14 to R18. When the curvature radii R1, R1 are larger than the above values, when the force is applied to the bottle container 10 in the longitudinal direction, the shoulder portion 13 of the bottle container 1 is easily plastically deformed. As described above, the bottle-shaped container 10 is filled with a tiled carton (not shown) when it is transported, and a plurality of corrugated boxes are stacked in sequence. At this time, a very strong force is applied to each of the bottle-shaped containers 10 in the longitudinal direction. In the present embodiment, the 'radius of curvature R1, R1 is larger than the radius of curvature R2, R3, but much smaller than the radius of curvature of the shoulder portion 13 itself. Therefore, it can be said that the shoulder portion 13 is raised in the direction of the axis of the container 1〇. State. That is, in the present embodiment, since the curvature radii R1, R1 are smaller than the curvature radius of the shoulder portion 13, the angle of the shoulder portion 13 with respect to the horizontal plane becomes large. Therefore, that is, applying a very powerful force to the bottle-shaped container 10 in the longitudinal direction, you are punishing, the shoulder portion 13 and the waist portion 15 of the bottle-shaped container 10 are also almost shaped, and most of the applied force is transmitted straight to the body. Part 45 below. Therefore, in the present embodiment, when the longitudinal force is applied, the bottle-shaped container 10 is settled more than the waist portion 15 at the upper portion, and the lower portion 45 of the body portion is mainly elastically deformed. That is, in the present embodiment, even if a force is applied to the bottle-shaped container 10 in the longitudinal direction, the shoulder portion 13 and/or the waist portion 15 are not bent in the oblique direction. Therefore, it is possible to prevent the shoulder portion 13 and/or the waist portion 15 from being damaged by plastic deformation. In addition, as is apparent from Fig. 1 and the like, the shoulder portion 13 of the bottle-shaped container 10 is smooth across the entire circumferential direction, and no ridge portion or the like is formed. Therefore, even when the longitudinal force is applied to the bottle type container 10, no stress is concentrated on the ridge portion. Therefore, there is no plastic deformation of such a bulge. Therefore, in the present embodiment, the shoulder portion 13 of the bottle type container 10 can be prevented from being plastically deformed. Further, in the present embodiment, the bottle type container 10 is described by a synthetic resin. However, the bottle type container 10 may be formed of other materials such as glass.
