底内面所封阻之狀態，故無法進行排出動作。故而，因於 上述吸入口與上述底内面之間設置微小間隙，故可使用較 上述口部至底板之深度為短之排出用管2。然而此時，在容 置物之排出時，將如第16圖所示，於樹脂製桶罐1之底部， 必將殘留其間隙量之容置物3，而無法全量排出。另，抽排 方式亦將朝罐内注入諸如氮氣等，以避免伴隨容置物3之排 出而使罐内形成負壓。 又，尤其上述之大型之樹脂製桶罐將如第16圖所示， 為確保容置容置物3時之剛性，而使樹脂製桶罐之底板4成 形具有其中央部分朝罐内側膨出成凸狀或圓弧狀之形狀 4a。另，第16圖中，已顯示自罐體外周朝中央按2階段形成 有凸形狀4a之樹脂製桶罐1。故而，在容置物排出結束時， 4 201118017 容置物3將聚集於底板4之周緣部分仙，而於罐内殘留至少 上述凸出或％出形狀4a之高度量之容置物3。 此時，使用較上述口部至底板之深度為長之排出用管 2 ’即可在排出用管2之先端偶然位於容置物3所聚集之周緣 部分4b側時，減少殘留量。然而，由排出用管2對上述口部 之安裝方法及排出用管2之硬度等諸多條件加以考量，則排 出用官2之先端並非常態配置於殘留容置物側，而單純使用 較長之排出用管2即可之構想，並非解決問題之良策。 又，上述加壓方式將使樹脂製桶罐1之内壓昇$，故如 第π圖所示，排出時殘留有容置物3之底板4亦將朝外側膨 出’而於底板4上形成凹部4c。因此，加壓方式將使容置物 3亦殘留於上述凹部4c，一般而言，與抽排方式相較，加壓 方式之容置物3之罐内殘留量較多。故而，採用加壓方式之 樹脂製桶罐使用者須於與樹脂製桶罐1連接之容置物排出 用裝置側採用減少殘留量之設計’而成問題。 另，上述之半導體範疇及液晶範疇所使用之藥液等價 格極高，由成本面加以考量’則樹脂製桶罐使用者極欲減 少殘留量。故而’樹脂製桶罐使用者強烈要求瓶罐廠商進 行減少殘留量之改良。 進而，伴隨近年對資源及環境之重視意識’對使用後 之樹脂製桶罐之回收要求亦已提高。上述樹脂製桶罐之回 收時，罐内之殘留物係無用物品，而須進行廢液處理’產 生處理費用。因此’由上點而言亦要求減少殘留量。 此外，樹脂製桶罐一如上述係藉吹塑而製成’其罐體 201118017 内面上沿著一對模具彼此之直線狀之接縫而形成有分模線 (PL)，並產生沿著上述分模線而朝罐内側凸起樹脂材料而 成之厚塊（突起）。因此，因上述厚塊而使容置物3之殘留量 減少時，亦將發生容置物3分為二部分之狀態。對此，排= 用管為1支，故亦將發生僅可排出分為二部分之單側之容置 物3之問題。上述之樹脂製桶罐亦有特殊構造而導致之殘留 量減少之必要性。且，上述厚塊之高度與樹脂製桶罐之厚 度成比例。因此，具有1〇〇〜200公升程度之較大内容量之大 型树知製桶罐將增加上述之由構造導致之殘留量減少 要性。 本發明係因應上述之問題及要求而設計者，目的在提 供-種可較以往減少容置物之容器内殘留量之樹脂製容器 及複合容器，以及上述樹脂製容器之製造方法。 用以欲解決課題之手段 為達成上述目的，本發明之構成如下。 即，本發明第1態樣之樹脂製容器可藉—對模具吹塑執 塑性樹脂而製成，並可通過排出用管而排出容置物，且；

Description of the Invention: [Technical Field of Invention] 3 Field of the Invention The present invention relates to a resin container such as a resin can made of a polyethylene material or the like, and the inner container is loaded into the exterior. A composite container formed in a container, and a method of producing the above resin container. BACKGROUND OF THE INVENTION For example, there has been a barrel made of a resin such as a polyethylene tub and a plastic tub which can be blow molded using a thermoplastic resin material such as a polyethylene material. The resin cans described above are superior in chemical resistance and corrosion resistance to steel cans, and are often used as containers for containing chemical liquids such as semiconductors and liquid crystals. In addition, examples of the above chemical liquid are in the semiconductor category such as CMP slurry, photoresist, developer, contact liquid, cleaning liquid, etc., in the liquid crystal nozzle, it is a photoresist, a color photoresist, and a color filter. Materials, etc. The above-mentioned resin cans are various in size, but the capacity of a large person is also such as a 20-liter type. When the large-sized resin can is discharged from the container, it is difficult to incline the can itself and discharge the contents. Therefore, the discharge method is a method in which the discharge pipe is inserted into the tank from the mouth portion formed in the opening portion of the top plate of the can body, and the discharge pipe is discharged through the discharge pipe, and the container is sucked out by the pump. The pumping method, or injecting nitrogen gas into the tank, pressurizes the tank to a pressure of about 5 to 200 kPa to pressurize the container. 3 201118017 [Pre-existing technical literature] [Non-patent literature] [Non-Patent Document 1] "SEKISUI POLY-DRUM", "SEKISUI POLY-DRUM", (issued in September, 2006) [Non-Patent Document 2] Sekima molding industry ( SUMMARY OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The above-described methods of pumping and pressurizing are all applicable to a container. Discharge and use the discharge tube. At this time, in a state where there is no gap between the suction port of the discharge pipe and the inner surface of the bottom of the resin can, the suction port is in a state of being blocked by the bottom inner surface, so that the discharge operation cannot be performed. Therefore, since a small gap is provided between the suction port and the bottom inner surface, the discharge pipe 2 having a shorter depth from the mouth portion to the bottom plate can be used. However, at this time, when the contents are discharged, as shown in Fig. 16, at the bottom of the resin can 1, the contents of the gap 3 are surely left, and the entire amount cannot be discharged. In addition, the pumping method will also inject a nitrogen gas or the like into the tank to avoid a negative pressure in the tank accompanying the discharge of the container 3. Further, in particular, as described in the above-mentioned large-sized resin can, as shown in Fig. 16, in order to secure the rigidity when accommodating the container 3, the bottom plate 4 of the resin can is formed with its central portion bulging toward the inside of the can. Convex or arc-shaped shape 4a. Further, in Fig. 16, a resin can 1 in which a convex shape 4a is formed in two stages from the center of the outer circumference of the can is shown. Therefore, at the end of the discharge of the contents, 4 201118017, the contents 3 will gather on the peripheral portion of the bottom plate 4, and at least the above-mentioned contents 3 of the height or the shape 4a of the shape 4a remain in the can. In this case, the discharge pipe 2' having a longer depth from the mouth portion to the bottom plate can be used to reduce the residual amount when the tip end of the discharge pipe 2 is accidentally placed on the side of the peripheral portion 4b where the container 3 is collected. However, in consideration of various conditions such as the method of attaching the mouth portion and the hardness of the discharge tube 2 by the discharge tube 2, the tip end of the discharge member 2 is disposed in the abnormal state on the side of the remaining container, and the discharge is simply used. The idea of using tube 2 is not a good solution to the problem. Further, the above-described pressurization method causes the pressure inside the resin can 1 to rise by $, so that the bottom plate 4 in which the container 3 remains at the time of discharge will also bulge outwardly on the bottom plate 4 as shown in Fig. π. Concave portion 4c. Therefore, the pressurization method causes the container 3 to remain in the recessed portion 4c as well, and generally, the amount of the residual material in the tank of the pressurized method is larger than that of the pumping method. Therefore, the user of the resin-made canister using the pressurized method has to be designed to reduce the amount of residue in the apparatus for discharging the container connected to the resin can 1 . In addition, the liquid crystals used in the above-mentioned semiconductor category and liquid crystal category are extremely expensive, and are considered by the cost side. The resin can user wants to reduce the amount of residue. Therefore, 'resin barrel users strongly urge bottle manufacturers to reduce the amount of residue. Furthermore, with the emphasis on resources and the environment in recent years, the recycling requirements for resin cans after use have also increased. When the above-mentioned resin can is recovered, the residue in the can is a useless item, and the waste liquid treatment is required. Therefore, from the previous point, it is also required to reduce the amount of residue. In addition, the resin cans are formed by blow molding as described above, and a mold line (PL) is formed on the inner surface of the can body 201118017 along a straight line along a pair of molds, and is produced along the above-mentioned manner. A thick block (protrusion) formed by projecting a resin material toward the inside of the can. Therefore, when the residual amount of the container 3 is reduced by the above-mentioned thick block, the state in which the container 3 is divided into two is also generated. In this regard, the row = tube is one, so that the problem that only one side of the container 3 divided into two parts can be discharged. The above-mentioned resin cans also have a special structure and the necessity of reducing the amount of residue. Moreover, the height of the above-mentioned thick block is proportional to the thickness of the resin can. Therefore, a large-sized tree-shaped can having a large amount of content of 1 〇〇 to 200 liters will increase the amount of residue caused by the above-mentioned structure.

C實施方式U 用以實施發明之形態 以下將就本發明之實施例之樹脂製容器及複合容器以 及上述樹脂製容器之製造方法，參照圖示加以說明。另， 各圖中已就同一或相同之構成部分附以相同之標號。又， 上述複合容器相當於將樹脂製之内裝容器裝填於剛性大於 該内裝容器之外裝容器内而成之雙重容器。 第1實施例： 第1圖顯示了本實施例之樹脂製桶罐101。在此，樹脂 製桶罐101相當於樹脂製容器之一例。又，上述樹脂製容器 12 201118017 不限於樹脂製桶罐10丨般之圓筒形狀，亦可為諸如方形等 其形狀並無限制。 樹脂製桶罐ΗΠ與上狀習知之相同，係 使用-對模具吹塑諸如聚乙烯材料等熱塑性樹脂材料而製 成。又，因採用吹塑，故罐内面上將形成朝縱向將上述樹 脂製桶罐UH二等分而對應上述—龍具彼此之接合部分 之直線狀之分模線(PL)1G7(第2圖）。該分模㈣7與分模線 1〇7以外之罐㈣妹，於_側沿分模線1G7形成有凸狀 之厚塊。 又，一如參照第16圖之說明，習知之樹脂製桶罐丨之底 板4為確絲置容置物時之祕，而於其巾央部分成形為朝 罐内側膨出成凸狀或圓弧狀之形狀4a。如第丨圖所示，本實 施例之樹脂製桶罐丨01之底板104亦相同，將底板中央部分 成形為朝罐内側101a膨出成凸狀或圓弧狀之形狀如。 本實施例之樹脂製桶罐101中，除於底板1〇4上形成上 述形狀104a以外，進而成形有上述樹脂製桶罐1〇1之特徵構 成部分之-之殘留量減少用凸部110。以下則就殘留量減少 用凸部110加以詳細說明。 樹脂製桶罐101之頂板105上，與習知之樹脂製桶船相 同，於沿著頂板105之直徑方向之二部位成形有口部i〇6a、 106b。口部106a、106b係可供進行容置物之注入及排出之 頂板105上之開口部，為排出容置物而使用排出用管丨〇2 時，則朝口部106a、106b之任一方如第丨圖所示般朝諸如口 部106a插入排出用管102，他方則安裝諸如氮氣注入管。 13 201118017 另’口部106a、106b具有可將罐内側l〇la保持氣密狀態之 構造。又，本實施例之樹脂製桶罐101與習知相同，採用上 述之抽排方式或加壓方式作為使用排出用管102之容置物 之排出方法。又，亦可構成對口部106a、106b之任一方安 裝排出用管102及上述氮氣注入管雙方。此時，他方之口部 則予以密閉。 又，口部106a、106b位於上述一對模具之接合部分。 故而’口部106a、106b位於上述分模線107上。 排出用管102在本實施例係樹脂製而具備可撓性之管 體。另，排出用管102可至少於先端部分具備可撓性，其亦 可不以樹脂材料製成整體，亦可不整體具備可撓性。 殘留量減少用凸部110在底板104上，對應上述之口部 中為排出用管102所插入之口部（以下為方便說明，將對應 第1圖而標示「l〇6a」）之正下方之位置上，如第2圖所示， 其於底板104之局部上朝罐内側i〇ia成形為凸狀。另，第2 圖中，雖顯示對應口部l〇6a、l〇6b而於底板1〇4上成形有2 個殘留量減少用凸部110之形態，但至少對應排出用管1〇2 所插入之口部l〇6a而成形一個殘留量減少用凸部n〇即可。 另’第2圖所示之殘留量減少用凸部11〇、以下將說明 之第5A圖所示之殘留量減少用凸部118及第5B圖所示之殘 留量減少用凸部119均以分模線107為中心而成形為左右對 稱之形狀，但不限於此，亦可形成左右非對稱之形狀。 上述之殘留量減少用凸部11〇包含傾斜面lu。該傾斜 面111係與經口部106a而插入之排出用管1〇2之先端1〇2&抵 14 201118017 接，且可朝罐内之殘留容置物3側導弓丨上述先端1〇2a之斜 面。上述傾斜面111係配置成在容置物排出結束之前，諸如 殘留容置物3聚集於底板104之周緣部分j〇4b側時，可如第1 圖所示，朝周緣部分104b側導引排出用管1〇2之先端1〇2&。 另，周緣部分104b相當於底板104中除上述膨出之形狀丨〇如 以外之部分。 而，一如以上之說明，藉上述加壓方式進行容置液之 排出時，底板104之中央部104c亦可能朝罐外側膨出而呈凸 狀，殘留容置物3則聚集於中央部104c側。此時，則如第3 圖所示，配置傾斜面111以朝中央部10如側導引排出用管 102之先端102a。 另’在容置物排出結束之前，殘留容置物3將聚集於周 緣部分104b側或中央部10牝側則可事先加以預測。即，採 用抽排方式時，將聚集於周緣部分104b側，採用加壓方式 時，則可基於底板104之上述形狀4a之形態及尺寸等及加壓 壓力而加以預測。故而，可設計傾斜面111之設置位置。 排出用管102之先端102a之朝底板104之周緣部分l〇4b 側或中央部104c側之導引方向可視傾斜面111之設置位置 而加以決定。即，如上所述，於排出用管102所插入之口部 106a之正下方設置傾斜面111，而通過口部106a之排出用管 102則沿垂直線或略垂直線而降入罐内。故而，欲朝底板1〇4 之周緣部分104b側定向排出用管102之先端102a時，則如第 4A圖所示，使殘留量減少用凸部110之最頂部112位於較排 出用管102之降下位置102b更偏中央部l〇4c側處即可。另， 15 201118017 欲朝底板104之中央部104c側定向排出用管102之先端i〇2a 時，則如第3圖所示，使上述最頂部112位於較上述降下位 置102b更偏底板104之周緣部分104b側處即可。如此，即可 設計排出用管102之導引方向。 殘留量減少用凸部110之形狀之一例係第2圖所示之形 狀，上述傾斜面111及上述最頂部112則沿底板104之周緣方 向而彎曲延伸。又，第2圖所示之殘留量減少用凸部11 〇之 一實施例中，長度L至少需在40mm程度。此因長度L小於該 值時，排出用管102之先端102a可能無法朝殘留容置物3側 確貫進行定向之故。又，底板1〇4之最底面至最頂部112之 高度Η乃6〜50mm程度。高度Η若小於6mm，排出用管1〇2之 先端102a可能無法朝殘留容置物3側確實進行定向，故不適 用’而，大於50mm時，則殘留量減少用凸部11〇之形狀將 大型化’故吹塑時，將有害於殘留量減少用凸部11〇之成形 性’而可能發生樹脂製桶罐101之基本強度降低等問題，故 不適用。 又’傾斜面111之角度相對於底板104之水平部分而為 約10度至約80度，而以45度至60度程度為佳。傾斜面111具 備約10度至約80度之傾斜角度，即可更確實地朝殘留容置 物3側定向排出用管1〇2之先端102a。 又’殘留量減少用凸部110之形狀不限於第2圖所示 者。舉例言之’亦可採用第5A圖所示之殘留量減少用凸部 117及第5B圖所示之殘留量減少用凸部118之形狀。 第5A圖之殘留量減少用凸部117具有c字狀或倒匚字 16 201118017 狀之平面形狀，以將排出用管102之先端102a配置於分模線 107之附近。即’殘留量減少用凸部117包含可將排出用管 102之先端102a定位於分模線1〇7附近之位置管制部117a、 117b。 另，朝底板104之中央部l〇4c側定向排出用管102之先 端102a時，位置管制部117a' 117b將與第5A圖之情形相反， 而改朝中央部104c進行定向。 第5B圖之殘留量減少用凸部！ 18包含沿著分模線1〇7而 延伸之中央突出部118a，以避開分模線107而配置排出用管 102之先端l〇2a。 進而’在對應口部106a、106b而於底板104上成形2個 殘留量減少用凸部11〇之形態中，如第6圖所示，亦可連結 兩殘留量減少用凸部n0之最頂部112，且按膨出成凸狀或 圓弧狀之形狀l〇4a之相同高度，與形狀l〇4a—體成形之。 參照第1圖及第4 A〜4 C圖說明構成如以上之說明之殘 留量減少用凸部110之動作。另，在此，殘留量減少用凸部 110係例不成形於底板104上’而朝底板104之周緣部分104b 側定向排出用管102之先端102a者。 插入樹脂製桶罐101之口部106a，且通過口部i〇6a而沿 垂直方向或略垂直方向降下之排出用管102之先端i〇2a，如 第4A圖所示’與相對於殘留量減少用凸部η 〇之最頂部112 而位於底板10 4之周緣部分1 〇 4 b側之殘留量減少用凸部i! 〇 之傾斜面111抵接。然後，進而插入排出用管102，而如第 及C圖所示，排出用管102之先端1 〇2a將為傾斜面111所 17 201118017 導引而降下，並定位於底板104之周緣部分104b側。 故而，在容置物排出結束之前，殘留容置物3聚集於底 板104之周緣部分_側時，可將排出用管呢之先端购 定位於周緣部分104b側。 如此，依據本貫施例之樹脂製桶罐101，可使排出用管 102之先端l02a確實配置於容置物排出結束之前殘留容置 物3所聚集之底板104處，即周緣部分1〇仆側或中央部1〇牝 側，而可排出殘留容置物3。因此，依據本實施例之樹脂製 桶罐101，可較以往減少容置物3之罐内殘留量。 另，如第4B及4C圖所示，排出用管1〇2與殘留量減少 用凸部110抵接，而略微彎曲。進而，為極力減少罐内之容 置物3之殘留量’而如第4C圖所示，須使排出用管1〇2 之先端102a儘可能接近底板104之内面。故而，設有 殘留量減少用凸部11〇時之排出用管1〇2之長度依申 请人之貫驗結果’且相對於口部106a至底板1〇4内面 之規定之垂直方向深度’設成更長5〜60mm程度。 又，本實施例之樹脂製桶罐101中，殘留量減少用凸部 110之成形係僅對可進行吹塑之習知模具安裝用以成形殘 留量減少用凸部110之凸狀之構件即完成，無須新製模具整 體。故而，本實施例之樹知製桶罐101可藉極低成本獲致極 大效果，而較為適用。 第2實施例： 上述第1實施例之樹脂製桶罐101係僅於與口部106a對 向之底板104之局部成形有殘留量減少用凸部11〇之形態。 18 201118017 相對於此，第7圖所示之本第2實施例之樹脂製桶罐1〇丨_2則 包含成形於底板104-2全周上之殘留量減少用凸部131。 另，樹脂製桶罐101-2中’底板104-2以外之構成部分與上述 之樹脂製桶罐101之構造無差異。故而，以下僅就成形於底 板104-2上之殘留量減少用凸部丨31進行說明。 底板104-2如第7圖所示，包含成形於底板104-2之全周 上之傾斜面111-2。傾斜面111_2與上述之傾斜面π!相較， 僅有長度不同，其功能與上述之傾斜面111相同。第2實施 例之樹脂製桶罐101-2係預設成在容置物排出結束之前，殘 留容置物3將聚集於底板1 〇4-2之周緣部分1 〇4b-2側之型態 者。因此’傾斜面111-2之最頂部112-2相對於自口部l〇6a 降下之排出用管102之先端l〇2a而位於底板104-2之中央部 l〇4c-2側。故而’上述降下後之排出用管1〇2將朝上述周緣 部分104b-2側定向。又，傾斜面Hi-2距離底面之高度^^可 採用與第1實施例中之傾斜面U1之高度Η相同之值。 本樹脂製桶罐101-2中，如第7圖所示，上述最頂部112-2 至底板104-2之中央部i〇4c-2已成形為平坦面。然而，並不 限於該形態’上述中央部l〇4c-2亦可成形為凹狀。 又’本第2實施例之樹脂製桶罐ι〇ι_2在容置物排出結 束之前，殘留容置物3聚集於底板104-2之中央部l〇4c-2側之 型態下’將如第8圖所示’使最頂部112_2相對於上述降下 之排出用管102之先端l〇2a而位於底板104-2之周緣部分 l〇4b-2側’以於底板1〇4_2之全周上成形傾斜面1112。又， 中央部104c-2則成形為凹狀。 201118017 第3實施例： 第1實施例及第2實施例中均因製造方法而如上所述， 於樹脂製桶罐101、1〇1_2之内面上，沿著分模線107而形成 有朝罐内側l〇la形成凸狀之厚塊（突起）。故而，諸如第1圖 所示之樹脂製桶罐101將如第9A圖所示，聚集於底板1〇4之 周緣部分104b側之殘留容置物3將因沿著直徑方向而延伸 於底板104上之上述突起i〇7a，而隔分成殘留容置物3a與殘 留容置物3b。而，上述現象亦發生在上述之其它形態之任 一種樹脂製桶罐之底板上。 如此，一旦殘留容置物3隔分成2部分，則即便使用殘 留量減少用凸部110等進行排出用管102之先端102a之定 向’亦可能發生僅可排出單側量之殘留容置物3之狀態。 因此，本實施例之樹脂製桶罐1〇1_3即如第9B圖所示， 於底板104之周緣部分i〇4b設有不具突起107a之非突起領 域141。另，本實施例係例示殘留容置物3將聚集於底板1〇4 之周緣部分104b之樹脂製桶罐101者，故於周緣部分i〇4b形 成有非突起領域141，但總言之，在容置物排出結束之前， 於底板104上對應殘留容置物3聚集之處而形成非突起領域 141即可。 形成非突起領域14卜即可消除將殘留容置物3分為2部 分之堰部。故而，依據本實施例之樹脂製桶輯m，可使 殘留容置物3流動至底板ΠΜ之任何部位，並可則支排出用 管102而排出殘留容置物3。如此， 依據本貫施例之樹脂製 桶罐101-3，即可藉與殘留量減少 用凸部110等之相乘效 20 201118017 果，進而減少容置物3之罐内殘留量。 第4實施例： 以上已s兒明之第1貫施例至第3實施例中，已就藉樹脂 材料之吹塑而成形之單體容器之樹脂製桶罐1〇1等加以說 明。而，远今，亦存在將樹脂製而經吹塑之内裝容琴裝填 於剛性大於上述内裝容器之諸如鋼製之外裝容器内而成之 雙重容器所構成之稱為複合容器之容器。舉例言之，已存 在主要為10〜20公升用之複合桶罐及主要為6〇〜2〇〇公升用 之一般名稱為化學罐(chemi drum)等稱呼之罐體。該等複合 容器亦自設於上部之口部插入排出用管，並藉上述加壓方 式或上述抽排方式排出容置物。另，上述内裝容器之底板 上，並未如樹脂製桶罐101等般，於底板1〇4上成形有底板 中央部分朝罐内側l〇la膨出成凸狀或圓弧狀之形狀1〇4a。 又，上述内裝容器不限於圓筒形狀’其形狀並無限制。 因此，第1實施例至第3實施例中已說明之殘留量減少 用凸部110、131—如第1〇圖所示，亦可應用於上述複合桶 罐及上述化學罐中之樹脂製且經吹塑之上述内裝容器，而 獲致與第1實施例至第3實施例相同之效果。 第10圖所示之複合容器150中，樹脂製且經吹塑之内裝 谷器151於底板部分設有相當於殘留量減少用凸部“ο、〖Μ 之殘留量減少用凸部152。另，複合容器15〇係圖示了相當 於上述複合桶罐之容器作為一例者。又，複合容器1 %中， 僅成形有口部l〇6a，但當然亦可成形2個口部。又，第圖 所示之上述複合桶罐多採上述加壓方式進行容置物之排 21 201118017 出。故而，第10圖所示之殘留量減少用凸部152呈現已成形 而可朝容器中央部側定向排出用管102之狀態。然而，殘留 量減少用凸部152當然亦可成形而朝容器之周緣側定向排 出用管102。 又，亦可就殘留量減少用凸部152應用第1實施例至第3 實施例中已說明之殘留量減少用凸部之變形例，而獲致相 同之效果。 上述之第1實施例至第4實施例中，底板上設有殘留量 減少用凸部110、117、118、131、152。而，以下將說明之 第5實施例及第6實施例中，則就未於底板上設置殘留量減 少用凸部，而可較以往減少容置物之罐内殘留量之樹脂製 桶罐加以說明。在此，第5實施例及第6實施例中，將以上 述之第1實施例至第3實施例中已說明之單體容器之樹脂製 桶罐内不具上述殘留量減少用凸部之形態之樹脂製桶罐為 例而說明之。故而，與第1實施例至第3實施例之樹脂製桶 罐相同之構成部分將附以相同之標號而在此省略其說明。 又，第5實施例及第6實施例之樹脂製桶罐係採用藉抽 排方式排出容置物3之方式。故而，容置物3將殘留於底板 104之周緣部分104b。 第5實施例： 第11A圖所示之本第5實施例之樹脂製桶罐201與諸如 第1實施例之樹脂製桶罐101相同，係使用一對模具吹塑諸 如聚乙稀材料等熱塑性樹脂材料而製成。因此，罐内面上 將形成上述分模線(PL)107。前述分模線107則一如上述， 22 201118017 與分模線107以外之罐内面相較，其於罐内側沿著分模線 107而形成有凸狀之厚塊即突起l〇7a。又，底板104亦與第1 實施例等相同，其底板中央部分成形為朝罐内側l〇la膨出 成凸狀或圓弧狀之形狀104a。 另，樹脂製桶罐201之底板104上一如上述，並未形成 殘留量減少用凸部。 具有上述構造之樹脂製桶罐201與上述第3實施例之構 造相同，一如第UA圖所示’於底板104之周緣部分104b設 有不具突起107a之非突起領域141。另，本實施例中，係以 殘留容置物3將聚集於底板1 〇 4之周緣部分1 〇 4 b之樹脂製桶 罐201為例，故於周緣部分104b形成有非突起領域141，但 總言之，在容置物排出結束之前，於底板104上對應殘留容 置物3所聚集之處而形成非突起領域mi即可。又，如第11A 圖所示，本實施例中，非突起領域141雖沿分模線1〇7而形 成於周緣部分l〇4b之全域上，但亦可如第11B圖所示，僅形 成於周緣部分l〇4b之局部。 如上所述，形成非突起領域141，即可如第3實施例之 5兄明，使殘留容置物3不致為底板1〇4分隔成2部分，且亦可 流動至底板1G4之任何部位，並藉i支排出用管呢將殘留容 置物3排出。故而，可較以往減少容置物3之罐内殘留量。 非突起領域141之形成在本實施例巾係進行如下。 即’使用一對模具吹塑熱塑性樹脂材料而製成樹脂製 桶罐2〇1。製成後，在上述熱塑性樹脂材料冷卻硬化前，如 圖斤示使加壓構件25〇通過位於分模線⑽正上方並 23 201118017 供排出时ι〇2插人之口部⑽而降下，並使其與突起職 抵接、並加以下壓而予以壓扁以形成非突起領域i4i。藉 此，非突起領域141即形成與底板1〇4之周緣部分1〇朴大致 相同之平面。 加壓構件250於其先端設有鋼製之壓扁部251。該壓扁 部251具備可通過口部10如之大小，且具有可至少覆蓋突起 l〇7a之大小，係用於形成非突起領域141之構件。上述加壓 構件250與推壓裝置255連接，藉推壓裝置255則可自動地進 行朝樹脂製桶罐201之插入 '降下、壓扁、退出樹脂製桶罐 201之各動作。又，進行壓扁動作時，加壓構件25〇宜加溫 至與樹脂製桶罐201之溫度相同程度。另，壓扁動作時，於 樹脂製桶罐201外側之底板1〇4上配置有諸如鋼製之支承板 252。 另，如上所述，非突起領域141在本實施例中，係形成 與底板104之周緣部分1 〇4b大致相同之平面，但亦可形成較 周緣部分104b更凹陷。如此將非突起領域141形成凹部時， 可使容置物3之殘留物集中於非突起領域141部分，再於非 突起領域141配置排出用管1〇2之先端，則具備可更有效率 地排出餘液之優點。 又，亦可在口部106a以外，進而對應口部106b而形成 非突起領域141。 第6實施例： 如上所述，本第6實施例之樹脂製桶罐亦與第5實施例 之樹脂製桶罐201相同，於底板104上並未形成殘留量減少 24 201118017 用凸部。 而，第13A圖所示之本第6實施例之樹脂製桶罐202中， 於底板104之周緣部分104b形成有集液用斜面213a-l、 213a-2、213b-l、213b-2(亦可總稱為集液用斜面213)。該等 集液用斜面213係自對分模線1〇7呈直角相交之直徑位置 211a、21 lb(亦可總稱為直徑位置211)朝分模線位置212a、 212b(亦可總稱為分模線位置212)呈朝下傾斜狀態之斜面。 另，本實施例中，如第13A及13B圖所示，直徑位置211雖 位於與膨出之形狀l〇4a部分相同或略同高度程度之處，但 並不限於此，僅須位在形狀1 〇4a部分以下，而高於分模線 位置212之高度程度即可。 如上所述，於底板104之周緣部分104b形成集液用斜面 213 ’即可使周緣部分丨〇4b之殘留容置物3聚集於分模線位 置212a、212b即與口部i〇6a、l〇6b對應之位置。故而，可 藉排出用管102而有效率地排出殘留容置物3，而較以往減 少容置物3之罐内殘留量。 另’本實施例中考量樹脂製桶罐202之成形上之理由， 而以直徑位置211a、211b作為最頂部，並如上述般形成集 液用斜面213以使殘留容置物3分別聚集於分模線位置

Embodiments for carrying out the invention The resin container and the composite container according to the embodiment of the present invention and the method for producing the resin container described above will be described with reference to the drawings. In the drawings, the same or similar components are denoted by the same reference numerals. Further, the composite container corresponds to a container in which a resin-made inner container is filled in a container having a rigidity larger than that of the inner container. First Embodiment: Fig. 1 shows a resin can 101 of the present embodiment. Here, the resin can 101 corresponds to an example of a resin container. Further, the above-mentioned resin container 12 201118017 is not limited to a cylindrical shape like a resin can 10, and may be, for example, a square shape, and the shape thereof is not limited. The resin cans are the same as those of the prior art, and are produced by blowing a thermoplastic resin material such as a polyethylene material to a mold. Further, since the blow molding is performed, a linear parting line (PL) 1G7 in which the resin cans UH are equally divided in the longitudinal direction and which correspond to the joint portions of the above-mentioned dragons is formed on the inner surface of the can (Fig. 2) ). The split mold (4) 7 and the tank (four) sisters other than the parting line 1〇7 are formed with a convex thick block along the parting line 1G7 on the _ side. Moreover, as described with reference to Fig. 16, the bottom plate 4 of the conventional resin cans is the secret of the silk to accommodate the contents, and is formed in the central portion of the towel to bulge into the convex or circular arc toward the inner side of the can. Shape 4a. As shown in the figure, the bottom plate 104 of the resin can 丨01 of the present embodiment is also the same, and the central portion of the bottom plate is shaped to bulge into the shape of the convex or arcuate shape toward the inner side 101a of the can. In the resin cans 101 of the present embodiment, in addition to the above-described shape 104a formed on the bottom plate 1A, the residual amount reducing convex portion 110 of the above-described characteristic portion of the resin can 1I1 is formed. Hereinafter, the residual amount reduction convex portion 110 will be described in detail. The top plate 105 of the resin can 10 is formed with the mouth portions i6a, 106b at two locations along the diameter direction of the top plate 105, as in the conventional resin drum boat. The mouth portions 106a and 106b are openings formed in the top plate 105 for receiving and discharging the contents, and when the discharge tube 2 is used for discharging the contents, one of the mouth portions 106a and 106b is the third side. The discharge pipe 102 is inserted into the port portion 106a as shown in the figure, and the nitrogen injection pipe is installed in the other. 13 201118017 The other mouth portions 106a and 106b have a structure in which the tank inner side l〇la can be kept in an airtight state. Further, the resin can 10 of the present embodiment is the same as the conventional method, and the above-described drawing method or pressurizing method is employed as the discharging method using the container for discharging the tube 102. Further, both of the pair of nozzle portions 106a and 106b may be provided with both the discharge pipe 102 and the nitrogen injection pipe. At this time, the mouth of the other side is sealed. Further, the mouth portions 106a and 106b are located at the joint portion of the pair of molds. Therefore, the mouth portions 106a and 106b are located on the above-mentioned parting line 107. The discharge pipe 102 is made of a resin in the present embodiment and has a flexible tubular body. Further, the discharge pipe 102 may be provided with flexibility at least at the tip end portion, and may not be made of a resin material as a whole or may not have flexibility as a whole. The residual amount reducing convex portion 110 is on the bottom plate 104, and corresponds to the mouth portion in which the discharge tube 102 is inserted in the above-described mouth portion (hereinafter, "1〇6a" will be referred to in the first figure for convenience of explanation). In the position shown in Fig. 2, it is formed in a convex shape on a part of the bottom plate 104 toward the inner side of the can. In the second embodiment, the two types of residual amount reducing projections 110 are formed on the bottom plate 1〇4 corresponding to the mouth portions 16a and 6b, but at least corresponding to the discharge tube 1〇2. It is sufficient to form a residual amount reducing convex portion n〇 by inserting the mouth portion l〇6a. Further, the remaining amount reducing convex portion 11A shown in Fig. 2 and the residual amount reducing convex portion 118 shown in Fig. 5A and the remaining amount reducing convex portion 119 shown in Fig. 5B will be The parting line 107 is shaped to be bilaterally symmetrical, and is not limited thereto, and may be formed in a left-right asymmetric shape. The above-described residual amount reducing convex portion 11A includes an inclined surface lu. The inclined surface 111 is connected to the tip end 1〇2& 1411818017 of the discharge tube 1〇2 inserted through the mouth portion 106a, and can guide the tip end 1〇2a toward the residual container 3 side in the tank. Beveled. The inclined surface 111 is disposed such that, when the remaining contents 3 are collected on the peripheral portion j〇4b side of the bottom plate 104 before the end of the discharge of the contents, the discharge tube can be guided toward the peripheral portion 104b side as shown in Fig. 1 . The apex of 1〇2 is 1〇2&. Further, the peripheral portion 104b corresponds to a portion of the bottom plate 104 other than the shape of the above-mentioned bulging. As described above, when the accommodating liquid is discharged by the above-described pressurization method, the central portion 104c of the bottom plate 104 may be bulged toward the outside of the can and may be convex, and the residual accommodating member 3 may be gathered on the central portion 104c side. . At this time, as shown in Fig. 3, the inclined surface 111 is disposed to guide the tip end 102a of the discharge pipe 102 toward the center portion 10 as the side. Further, before the discharge of the contents is completed, the residual contents 3 will be collected on the side of the peripheral portion 104b or the side of the central portion 10, and can be predicted in advance. In other words, when the drawing method is used, it is collected on the side of the peripheral portion 104b, and when it is pressurized, it can be predicted based on the shape, size, and the like of the shape 4a of the bottom plate 104 and the pressing pressure. Therefore, the set position of the inclined surface 111 can be designed. The guiding direction of the leading end 102a of the discharge pipe 102 toward the peripheral portion 104b side or the central portion 104c side of the bottom plate 104 can be determined by the position at which the inclined surface 111 is disposed. That is, as described above, the inclined surface 111 is provided directly below the mouth portion 106a into which the discharge pipe 102 is inserted, and the discharge pipe 102 passing through the mouth portion 106a is lowered into the tank along a vertical line or a slightly vertical line. Therefore, when the tip end 102a of the discharge pipe 102 is to be oriented toward the peripheral portion 104b side of the bottom plate 1A4, the topmost portion 112 of the residual amount reducing convex portion 110 is positioned closer to the discharge pipe 102 as shown in Fig. 4A. The lowering position 102b may be more at the side of the central portion l4c. Further, when the front end i〇2a of the discharge pipe 102 is to be oriented toward the central portion 104c side of the bottom plate 104, as shown in Fig. 3, the topmost portion 112 is located closer to the periphery of the bottom plate 104 than the lowering position 102b. The portion 104b can be on the side. Thus, the guiding direction of the discharge pipe 102 can be designed. One of the shapes of the residual amount reducing convex portion 110 is a shape shown in Fig. 2, and the inclined surface 111 and the topmost portion 112 are curved and extended in the circumferential direction of the bottom plate 104. Further, in the embodiment of the residual amount reducing convex portion 11 shown in Fig. 2, the length L needs to be at least about 40 mm. When the length L is smaller than this value, the leading end 102a of the discharge pipe 102 may not be accurately oriented toward the remaining container 3 side. Further, the height from the bottommost surface to the topmost portion 112 of the bottom plate 1〇4 is about 6 to 50 mm. If the height Η is less than 6 mm, the leading end 102a of the discharge pipe 1〇2 may not be oriented toward the remaining container 3 side, so it is not applicable. However, when it is larger than 50 mm, the shape of the residual amount reducing convex portion 11〇 is large. When the blow molding is performed, the moldability of the convex portion 11 is reduced, which may be harmful, and the basic strength of the resin can 101 may be lowered, which is not applicable. Further, the angle of the inclined surface 111 is about 10 to about 80 degrees with respect to the horizontal portion of the bottom plate 104, and preferably about 45 to 60 degrees. The inclined surface 111 has an inclination angle of about 10 degrees to about 80 degrees, so that the tip end 102a of the discharge pipe 1〇2 can be more surely directed toward the residual container 3 side. Further, the shape of the residual amount reducing convex portion 110 is not limited to that shown in Fig. 2. For example, the shape of the residual amount reducing convex portion 117 shown in Fig. 5A and the residual amount reducing convex portion 118 shown in Fig. 5B may be employed. The residual amount reducing convex portion 117 in Fig. 5A has a c-shaped or inverted shape 16 201118017 planar shape, and the leading end 102a of the discharge pipe 102 is disposed in the vicinity of the parting line 107. In other words, the residual amount reducing convex portion 117 includes position regulating portions 117a and 117b that can position the leading end 102a of the discharge pipe 102 in the vicinity of the parting line 1〇7. Further, when the leading end 102a of the discharge pipe 102 is oriented toward the center portion 10b side of the bottom plate 104, the position regulating portion 117a' 117b is reversed from the case of Fig. 5A, and is oriented toward the center portion 104c. The convex portion for reducing the amount of residue in Fig. 5B! 18 includes a central projection 118a extending along the parting line 1〇7, and the tip end l〇2a of the discharge pipe 102 is disposed to avoid the parting line 107. Further, in the form in which the two residual amount reducing convex portions 11 are formed on the bottom plate 104 in the corresponding mouth portions 106a and 106b, as shown in Fig. 6, the top of the two residual amount reducing convex portions n0 may be connected. 112, and formed into a convex or arc-shaped shape l〇4a at the same height, and formed into a shape l〇4a. The operation of the residual amount reducing convex portion 110 constituting the above description will be described with reference to Figs. 1 and 4A to 4C. Here, the residual amount reducing convex portion 110 is not formed on the bottom plate 104, and the leading end 102a of the discharge pipe 102 is oriented toward the peripheral edge portion 104b side of the bottom plate 104. The tip portion 106a of the discharge tube 102, which is inserted into the mouth portion 106a of the resin can 10 and lowered in the vertical direction or the direction of the vertical direction by the mouth portion 〇6a, as shown in Fig. 4A, is relative to the residual amount. The inclined surface 111 of the convex portion i! 〇 which is located on the side of the peripheral portion 1 〇 4 b of the bottom plate 104 is reduced by the topmost portion 112 of the convex portion η 抵 and is abutted. Then, the discharge pipe 102 is further inserted, and as shown in FIGS. C and C, the tip end 1 〇 2a of the discharge pipe 102 is guided by the inclined surface 111 17 201118017 and lowered, and positioned on the peripheral portion 104b side of the bottom plate 104. . Therefore, when the residual container 3 is collected on the peripheral portion_side of the bottom plate 104 before the discharge of the container is completed, the leading end of the discharge tube can be purchased on the side of the peripheral portion 104b. In this way, according to the resin canister 101 of the present embodiment, the tip end 102a of the discharge pipe 102 can be disposed at the bottom plate 104 where the residual container 3 is collected before the discharge of the container is finished, that is, the peripheral portion 1 is on the side or The central portion is on the side of the crucible, and the residual container 3 can be discharged. Therefore, according to the resin can 101 of the present embodiment, the amount of residue in the can of the container 3 can be reduced as compared with the prior art. Further, as shown in Figs. 4B and 4C, the discharge tube 1〇2 is in contact with the residual amount reducing convex portion 110, and is slightly curved. Further, in order to reduce the residual amount of the contents 3 in the can as much as possible, as shown in Fig. 4C, the leading end 102a of the discharge tube 1〇2 should be made as close as possible to the inner surface of the bottom plate 104. Therefore, the length of the discharge pipe 1〇2 when the residual amount reducing convex portion 11 is provided is set according to the applicant's inspection result 'and the predetermined vertical depth with respect to the inner surface of the mouth portion 106a to the bottom plate 1〇4'. The length is 5~60mm. Further, in the resin can 10 of the present embodiment, the molding of the residual amount reducing convex portion 110 is only a member for attaching the convex portion of the residual amount reducing convex portion 110 to a conventional mold which can be blow molded. Complete, no need to make new molds as a whole. Therefore, the tree-forming can 101 of the present embodiment can be extremely effective at a very low cost, and is more suitable. In the second embodiment, the resin cans 101 of the first embodiment are formed in a form in which the residual amount reducing projections 11 are formed only in a portion of the bottom plate 104 opposed to the mouth portion 106a. 18 201118017 In contrast, the resin can 1__2 of the second embodiment shown in Fig. 7 includes the residual amount reducing convex portion 131 formed on the entire circumference of the bottom plate 104-2. Further, the components other than the bottom plate 104-2 in the resin can 101-2 are not different from the above-described structure of the resin can 101. Therefore, only the residual amount reducing projections 31 formed on the bottom plate 104-2 will be described below. The bottom plate 104-2, as shown in Fig. 7, includes an inclined surface 111-2 formed on the entire circumference of the bottom plate 104-2. The inclined surface 111_2 is different in length from the inclined surface π!, and has the same function as the above-described inclined surface 111. The resin can 101 of the second embodiment is preset to be a type in which the residual contents 3 are collected on the side of the peripheral portion 1 〇 4b-2 of the bottom plate 1 〇 4-2 before the discharge of the contents is completed. Therefore, the topmost portion 112-2 of the inclined surface 111-2 is located on the side of the central portion l4c-2 of the bottom plate 104-2 with respect to the leading end l2a of the discharge pipe 102 lowered from the mouth portion 16a. Therefore, the discharge pipe 1〇2 after the lowering is oriented toward the side of the peripheral portion 104b-2. Further, the height of the inclined surface Hi-2 from the bottom surface can be set to the same value as the height Η of the inclined surface U1 in the first embodiment. In the resin can 1010, as shown in Fig. 7, the central portion i〇4c-2 of the uppermost portion 112-2 to the bottom plate 104-2 has been formed into a flat surface. However, the present invention is not limited to the above-described form. The central portion 10c-2c may be formed in a concave shape. Further, the resin cans ι〇ι_2 of the second embodiment are stacked before the end of the discharge of the contents, and the residual contents 3 are collected on the side of the central portion l4c-2 of the bottom plate 104-2. As shown in the figure, 'the topmost portion 112_2 is located on the side of the peripheral portion l〇4b-2 of the bottom plate 104-2 with respect to the leading end l〇2a of the descending discharge pipe 102' to form a slope on the entire circumference of the bottom plate 1〇4_2. Face 1112. Further, the central portion 104c-2 is formed in a concave shape. 201118017 Third Embodiment: In the first embodiment and the second embodiment, as described above, the inner surface of the resin cans 101 and 1_2 is formed along the parting line 107 by the manufacturing method. The inner side l〇la forms a convex thick piece (protrusion). Therefore, the resin can 101 as shown in Fig. 1 will be as shown in Fig. 9A, and the residual contents 3 collected on the peripheral portion 104b side of the bottom plate 1 4 will extend on the bottom plate 104 in the diametrical direction. The protrusion i〇7a is divided into a residual container 3a and a residual container 3b. However, the above phenomenon also occurs on the bottom plate of any of the above-mentioned other types of resin cans. When the remaining container 3 is divided into two parts, the state of the front end 102a of the discharge pipe 102 can be discharged by using the remaining amount reducing convex portion 110 or the like, and the state in which only the one-side amount of the residual container 3 can be discharged may occur. . Therefore, the resin can 1R_1_3 of the present embodiment, as shown in Fig. 9B, is provided with a non-protrusion field 141 having no protrusion 107a at the peripheral portion i〇4b of the bottom plate 104. In addition, in the present embodiment, the resin cans 101 which are gathered in the peripheral portion 104b of the bottom plate 1〇4 are exemplified, so that the non-protruding field 141 is formed in the peripheral portion i〇4b, but in general, Before the discharge of the contents is completed, the non-protrusion area 141 may be formed on the bottom plate 104 corresponding to the accumulation of the remaining contents 3. Forming the non-protrusion area 14 eliminates the division of the remaining container 3 into two parts. Therefore, according to the resin barrel m of the present embodiment, the residual container 3 can be caused to flow to any portion of the bottom plate, and the discharge tube 102 can be branched to discharge the residual container 3. As described above, according to the resin can 101 of the present embodiment, the residual amount of the projections 110 and the like can be multiplied by 20,180,180, thereby reducing the amount of residue in the container 3 of the container 3. (Fourth Embodiment) In the first to third embodiments of the above, a resin can 1R1 of a single container formed by blow molding of a resin material has been described. Moreover, far and present, there is also a container called a composite container which is formed by filling a resin-made blow molded inner piano with a double container which is more rigid than the above-mentioned inner container, such as a steel outer container. . For example, there are already known compound tanks for 10 to 20 liters and tanks which are commonly referred to as chemical tanks (chemi drums) for 6 〇 to 2 liters. The composite containers are also inserted into the discharge tube from the mouth portion of the upper portion, and the contents are discharged by the above-described pressurization method or the above-described pumping method. Further, the bottom plate of the inner container is not formed in the shape of a convex or arc-shaped shape on the bottom plate 1〇4, and the central portion of the bottom plate is bulged toward the inner side of the can. 〇 4a. Further, the above-described inner container is not limited to a cylindrical shape, and its shape is not limited. Therefore, the remaining amount reducing convex portions 110 and 131 described in the first to third embodiments can be applied to the resin in the above-described composite can and the chemical tank as shown in the first drawing. The above-described inner container was blow molded to obtain the same effects as those of the first to third embodiments. In the composite container 150 shown in Fig. 10, the resin-made inner blower 151 is provided with a convex portion 152 corresponding to the residual amount reducing convex portion "o" in the bottom plate portion. In addition, the composite container 15 is shown as an example of a container corresponding to the above-described composite can. Further, in the composite container, only the mouth portion 16a is formed in 1% of the composite container, but of course, two mouth portions may be formed. The above-mentioned composite drum tank shown in the figure is more than the above-mentioned pressurizing method for discharging the row 21 201118017. Therefore, the residual amount reducing convex portion 152 shown in Fig. 10 is formed to be oriented toward the center side of the container. In the state of the discharge pipe 102, the remaining amount reducing convex portion 152 may of course be formed to orient the discharge pipe 102 toward the peripheral side of the container. The first embodiment may be applied to the residual amount reducing convex portion 152. In the first to fourth embodiments, the first embodiment to the fourth embodiment are provided with the residual amount reducing convex portions 110 and 117 in the modified example of the residual amount reducing convex portion described in the third embodiment. , 118, 131, 152. And, the following will explain In the fifth embodiment and the sixth embodiment, the resin-made cans in which the residual amount of the contents of the container is reduced are not provided in the bottom plate, and the fifth embodiment is described. In the example and the sixth embodiment, the resin cans in the form of the above-described residual amount reducing convex portion are not included in the resin cans of the single-capacity containers described in the first to third embodiments. The same components as those of the resin cans of the first embodiment to the third embodiment are denoted by the same reference numerals and will not be described here. Further, the fifth embodiment and the sixth embodiment The resin cans are discharged in a manner of discharging the contents 3. Therefore, the contents 3 remain in the peripheral portion 104b of the bottom plate 104. Fifth Embodiment: The fifth embodiment shown in FIG. 11A The resin can 201 is made of a thermoplastic resin material such as a polyethylene material by a pair of molds, as in the resin can 101 of the first embodiment. Therefore, the above-mentioned parting line is formed on the inner surface of the can. (PL) 107. The aforementioned parting line 107 is as described above, 22 201118017, in contrast to the inner surface of the can other than the parting line 107, a convex piece, that is, a projection l〇7a is formed along the parting line 107 on the inner side of the can. Further, the bottom plate 104 is also the same as the first embodiment. The central portion of the bottom plate is formed into a convex or arc-shaped shape 104a toward the inner side of the can. Further, as described above, the bottom plate 104 of the resin can 201 does not have a projection for reducing the amount of residual. The resin can 201 having the above-described configuration is the same as that of the above-described third embodiment, and as shown in Fig. UA, 'the non-protrusion region 141 having no protrusion 107a is provided on the peripheral portion 104b of the bottom plate 104. In addition, this embodiment In the case of the resin can barrel 201 which is gathered around the peripheral portion 1 〇 4 b of the bottom plate 1 〇 4 by the residual container 3, the non-protrusion field 141 is formed in the peripheral portion 104b, but in general, it is contained. Before the end of the discharge of the contents, the non-protrusion area mi may be formed on the bottom plate 104 corresponding to where the residual contents 3 are gathered. Further, as shown in Fig. 11A, in the present embodiment, the non-protrusion region 141 is formed over the entire circumference of the peripheral portion 104a along the parting line 1〇7, but may be formed only as shown in Fig. 11B. Part of the peripheral part l〇4b. As described above, the non-protrusion field 141 is formed, that is, as shown in the fifth embodiment of the third embodiment, the residual container 3 is not divided into two portions for the bottom plate 1〇4, and may flow to any portion of the bottom plate 1G4, and The residual container 3 is discharged by the i-discharge tube. Therefore, the amount of residue in the tank of the container 3 can be reduced as compared with the prior art. The formation of the non-protrusion field 141 is performed as follows in the towel of this embodiment. Namely, a resin can is formed by blowing a thermoplastic resin material using a pair of molds. After the preparation, before the thermoplastic resin material is cooled and hardened, the pressing member 25 is lowered by passing through the mouth portion (10) which is placed directly above the parting line (10) and 23 201118017 for discharging. It is brought into contact with the projections and pressed with the following pressure to form a non-protrusion field i4i. Thereby, the non-protrusion area 141 forms a plane substantially the same as the peripheral portion 1 of the bottom plate 1〇4. The pressing member 250 is provided at its tip end with a flattened portion 251 made of steel. The flattened portion 251 has a size that can pass through the mouth portion 10 and has a size that can cover at least the projections 7a, and is used to form the non-protrusion region 141. The pressurizing member 250 is connected to the pressing device 255, and the pressing device 255 can automatically perform the operations of lowering, crushing, and exiting the resin can 201 into the resin can 201. Further, when the flattening operation is performed, the pressing member 25 is preferably heated to the same level as the temperature of the resin can 201. Further, at the time of the flattening operation, a support plate 252 made of steel is disposed on the bottom plate 1〇4 outside the resin can 201. Further, as described above, in the present embodiment, the non-protrusion field 141 is formed to have substantially the same plane as the peripheral portion 1 〇 4b of the bottom plate 104, but may be formed to be more recessed than the peripheral portion 104b. When the non-protrusion area 141 is formed into a concave portion as described above, the residue of the container 3 can be concentrated on the non-protrusion area 141, and the tip end of the discharge tube 1〇2 can be disposed in the non-protrusion area 141, so that the discharge can be discharged more efficiently. The advantage of the remaining liquid. Further, a non-protrusion region 141 may be formed in addition to the mouth portion 106a and further corresponding to the mouth portion 106b. Sixth Embodiment: As described above, the resin can of the sixth embodiment is also the same as the resin can 201 of the fifth embodiment, and the projections for the amount of reduction 24 201118017 are not formed on the bottom plate 104. Further, in the resin can 200 of the sixth embodiment shown in Fig. 13A, the liquid collecting slopes 213a-1, 213a-2, 213b-1, and 213b-2 are formed on the peripheral portion 104b of the bottom plate 104 ( It may also be collectively referred to as a liquid collecting slope 213). The slabs 213 are formed at right angles 211a, 21 lb (also collectively referred to as diametrical positions 211) that intersect at right angles to the parting line locations 212a, 212b (also collectively referred to as parting) The line position 212) is a slope that is inclined downward. Further, in the present embodiment, as shown in Figs. 13A and 13B, the diameter position 211 is located at the same or slightly the same height as the bulging shape l〇4a, but is not limited thereto, and only needs to be in the shape. 1 〇 4a portion below, and higher than the height of the parting line position 212. As described above, the liquid collecting slope 213' is formed in the peripheral portion 104b of the bottom plate 104, so that the residual contents 3 of the peripheral portion 丨〇4b can be collected at the parting line positions 212a, 212b, that is, with the mouth portions i〇6a, l〇. 6b corresponds to the location. Therefore, the residual container 3 can be efficiently discharged by the discharge pipe 102, and the residual amount in the tank of the container 3 can be reduced as compared with the prior art. In the present embodiment, the reason for forming the resin can 220 is considered, and the diameter positions 211a and 211b are the top portions, and the liquid collecting slope 213 is formed as described above so that the residual contents 3 are respectively gathered in the parting mold. Line positions 212a, 212b. However, in the peripheral portion 1 of the bottom plate 104, the topmost portion is not limited to the above-described diameter positions 21 la, 211b, and may be formed at any position. Further, as described above, the discharge pipe 102 is often provided in the mouth portion 106a. Therefore, it is preferable to form the liquid collecting slope 213 so that the residual container 3 is concentrated only on the corresponding mouth portion 1 such as the parting line position 212a. That is, as shown in Fig. 13C, it is preferable to form the liquid collecting slant 25 201118017 surface 213 with the parting line position 212b as the topmost portion and the parting line position 212a as the bottommost portion. The formation of the liquid collecting slope 213 is performed as follows in the present embodiment. In the description of Fig. 13A, the case where the liquid collecting slope 213 is formed with the diameter positions 211a and 211b as the topmost portion is taken as an example. Namely, a resin can is formed by blowing a thermoplastic resin material using a pair of dies. After the preparation, before the thermoplastic resin material is cooled and hardened, on the outer peripheral portion i〇4b of the bottom plate 1〇4 outside the resin can 202, as shown in Fig. 14, two portions 26la, 26lb are arranged on the circumference. The bulged bridge is using the mold 260. Further, the two portions 261a, 261b correspond to the diameter positions 211a, 211b, respectively. Next, in the state where the two portions 261a and 261b are in contact with the outer side of the bottom plate 1〇4, the correcting mold 26 is pushed toward the inside of the can. Thereby, the liquid collecting slope 213 can be formed in the peripheral portion 104b of the bottom plate 104. Further, in combination with the sixth embodiment and the fifth embodiment, it is also possible to form the peripheral portion 1 of the bottom plate 1〇4 in the portion of the parting line position m as in the resin can 203 shown in Fig. A resin can having a non-protruding field (4) and a liquid collecting slope 213 is provided. Further, this embodiment may be combined with the embodiment to form a resin can having a liquid collecting slope 213, a non-bumping area 141, and a residual amount reducing portion & Alternatively, the configurations of the above embodiments may be combined as appropriate. The above construction can achieve the individual effects of the combined embodiments.
