合成樹脂製壜体 発明の背景  Background of the Invention
本発明 は、 比較的大型の合成樹脂製壜体に関する も のであ る。  The present invention relates to a relatively large synthetic resin bottle.
2 軸延伸プロ一成形さ れたァ ク リ ロ 二 ト リ ル樹脂ま たはポ リ エチ レ ンテ レフ タ レー ト 樹脂製の埵体は、 そ の優れた機械的強度お よび透明性に よ り 多数利用 さ れ— て い る o  The biaxially stretch molded resin or polyethylene terephthalate resin itself has excellent mechanical strength and transparency. O Many are used
こ の 2 軸延伸ブロー成形さ れた合成樹脂製璦体は、 大別 して、 底部を半球弧状に膨出 さ せて耐内庄強度を 高め、 こ の底部に脚部を提供す るベ ー ス カ ッ プ ( ba s e cu p ) を組み付け た もの と、 ベース カ ッ プを組み付け る こ と な し に、 底部の中央部分を 内方 に陥没させて璦 本体自体に脚部を形成し た もの とがあ る。  The biaxially stretch blow-molded synthetic resin body is roughly divided into a base having a hemispherical bulge at the bottom to increase the inner shojo strength and providing a leg at the bottom. -With the base cup attached and without the base cup attached, the center of the bottom is depressed inward to form legs on the body itself. There are some.
璦本体自体に脚部を形成 し た ものは、 洗浄、 滅菌処 理、 成形お よび組立処理そ して全体的な外観体裁の点 で、 ベー ス カ ッ プを組み付けた璦容器 に対 し て優れて い る。 '  脚 Legs formed on the main body itself can be cleaned, sterilized, molded and assembled, and overall appearance can be compared to containers fitted with base cups. Are better. '
しか しなが ら、 堪本体自 体に脚部を形成 し た ものに あ っ て は、 壜の本体部分であ る胴部の太さ に比べて、 壜の起立を達成保持す る ために機能す る 実質的な底面 積が小さ く、 こ の ため決 して安定 し た壜の 自 立保持を 得る こ と がで き な い と 云 う 問題があ っ た。 However, in the case where the body itself is formed with legs, it is necessary to achieve the standing of the bottle in comparison with the thickness of the body, which is the main part of the bottle. Functional Substantial base area is small, thus ensuring a stable self-sustaining bottle There was the problem of not being able to get it.
すな わち、 底部を内方に陥没さ せ た周端部の湾曲反 転箇所を脚部と する場合、 こ の湾曲反転 し た箇所の最 下点は、 こ の脚部がブロー成形さ れる ものであ るので、 璦の胴部外周面よ り も 内方に位置 し、 こ の内方に位置 し た分だ け埵を起立姿勢に保持す る ための底面積が小 さ く な るのであ る。  In other words, if the bent portion at the periphery where the bottom is depressed inward is used as a leg, the lowest point of the bent portion is that the leg is blow molded. Therefore, it is located more inward than the outer peripheral surface of the torso, and the bottom area for holding only the inwardly located part in the upright posture is small. It is.
ま た、 壜本体自体に脚部を形成 し た もの に あ っ て は、 高い 内圧がかかる と、 脚部を形成 し-た底部に比較的大 き な膨大変形が発生 し、 こ の変形に よ り 起立保持能力 が大幅に低下す る と云う 問題があ り、 場合に よ っ て は こ の膨大変形が不正変形に発展す る 恐れがあ る と云 う 問題があ つ た。  In the case of the bottle body itself with legs formed, when a high internal pressure is applied, a relatively large and massive deformation occurs at the bottom where the legs are formed. There is a problem that the standing ability is greatly reduced, and in some cases, this huge deformation may develop into an irregular deformation.
そ し て、 塚体に安定し た 自立機能を付与す る 目 的で ¾本体に組み付け られるベース カ ッ プは、 組み付け対 象 と な る壜本体の底部が半球状に膨出 し た構造 と な つ て い る ので、 その高さが比較的大 き な もの と な ら ざる を得ず、 こ のため璦容器全体の外観に 占め るベース 力 ッ プの割合が大 き く な り、 璦本体が持つ優れた意匠効 果を充分に発揮で き ない と云 う 不満があ る と共に、 内 圧に よ る 底部の膨大不正変形を防止す る と 云 う 能力 は 全 く なかっ た。  The base cup, which is to be attached to the body, has a structure in which the bottom of the bottle body to be assembled has a hemispherical bulge. As a result, the height must be relatively large, and as a result, the proportion of the base cap occupying the entire appearance of the container increases, and He complained that the excellent design effects of the main body could not be fully exhibited, and had no ability to prevent the gigantic deformation of the bottom due to internal pressure.
さ ら に、 ァ ク リ ロ二 ト リ ル樹脂で成形さ れた大型 2 軸延伸ブロー成形璦体は、 底部の耐衝擊性が充分では な く、 こ の ため取 り 落 し に よ り 簡単 に底部に亀裂が発 生 し て し ま う と云う 問題があ っ た。 In addition, large biaxial stretch blow molded articles made of acrylic resin are not sufficiently impact resistant at the bottom, making them easier to remove. Cracks at the bottom There was a problem of being born.
発明の概要 Summary of the Invention
そ こ で、 本発明 は、 上記 し た従来技術にお け る問題 点を解消すべ く 発明 さ れた もので、 底部中央を内方に 反転陥没させて脚部を形成 し た璦体にお い て、 璦容器 に安定 し た脚部を提供する と 共に、 内圧に よ る底部の 膨大不正変形の発生を防止 し、 さ ら に璦体の底部の耐 衝擊強度を高め る こ と を 目 的 と し た ものであ る。  Therefore, the present invention has been made in order to solve the above-mentioned problems in the prior art, and has a body in which the bottom center is inverted and depressed inward to form a leg. In addition to providing stable legs to the container, it is also intended to prevent the occurrence of enormous deformation of the bottom due to internal pressure and to increase the impact resistance of the bottom of the body. It was targeted.
上記目 的を達成する ための本発明 の手段は、  Means of the present invention for achieving the above object are as follows:
球弧面状 と な っ た底部の外周面に幅広な組み付け凹 溝を陥没設 し た、 2 軸延伸ブロー成形さ れた合成樹脂 製の瑷本体を有す る こ と、  It has a biaxially stretched blow molded synthetic resin main body with a wide recessed groove recessed in the outer peripheral surface of the bottom that has a spherical surface.
こ の璦本体の胴部の外径 と ほぼ等 しい外径を有す る 直線短円筒片の上半部分を、 璦本体の組み付け凹溝内 に嵌合 して、 内周面であ る組付 き 球弧面を組付け凹溝 の溝底面に面接触させ る組付 き 筒片 と す る と 共に、 下 半部分を、 下端を壜本体の底部の最下端よ り も下位に 位置させ た脚筒片 と し た脚体 と を有す る こ と、 壜本体の底部の外周面に形成さ れ る組付け凹溝は、 下方ほ どその溝の深さ を大 き く し た構造 と す る のが有 効であ る。  The upper half of a straight short cylindrical piece having an outer diameter approximately equal to the outer diameter of the body of the main body is fitted into the mounting groove of the main body to form an inner peripheral surface. Along with the assembling cylindrical piece that makes the spherical surface of the assembling surface contact the groove bottom of the concave groove, the lower half is positioned with the lower end lower than the lowermost lower end of the bottom of the bottle body. And a concave groove formed on the outer peripheral surface of the bottom of the bottle body, the depth of the groove is increased from the bottom to the bottom. Is effective.
組付け凹溝は、 球弧面状 と な っ た 底部の外周面に陥 投状に形成さ れて い るので、 こ の組付 け凹溝の溝底面 に面接触す る脚筒片の組付 き 筒片 に 形成さ れた内周面 と して の組付 き球弧面は、 上方に拡がっ た テーパー面 構造 と な っ て お り、 こ の ため脚体に対 し壜本体の底部 を上方から押 し込むだけで、 脚体の組付 き 筒片の内周 面倒部分が組付け凹溝内 に嵌合し、 脚体の璦本体に対 す る組付 Jナが達成さ れる。 Since the mounting groove is formed in a concave shape on the outer peripheral surface of the bottom having a spherical arc shape, the leg tube piece which is in surface contact with the groove bottom surface of the mounting groove is formed. Inner peripheral surface formed on assembled cylinder As a result, the assembled spherical arc surface has a tapered surface structure that expands upward, so that simply pushing the bottom of the bottle main body against the leg from above, The inner peripheral troublesome portion of the assembled cylinder piece fits into the assembly concave groove, and the assembling of the leg body to the main body is achieved.
こ の璦本体に対する脚体の嵌合組み付け に際 し、 組 付け凹溝を'下方ほど溝深さ を大き く 構成 して、 組付け 凹溝の下方の溝縁に比較的大き い高さ の膨出部を付形 して お ぐと、 深 く な つ た組付け凹溝 に対応 し て脚体の 組付 き筒片の組付 き球弧面の下端部 に突出形成さ れた 係止条力 こ の膨出部に強 く 係止す る こ と にな り、 こ の膨出部に対する係止条の係止に よ り、 埵本体に対す る脚体の嵌合組付 き を き わめて強固な もの と す る こ と にな る。  When the legs are fitted to the main body, the depth of the mounting groove is configured to be larger downward, and the height of the groove is relatively large at the groove edge below the mounting groove. When the bulging portion is shaped and engaged, the projections are formed at the lower end of the spherical arc surface where the leg is assembled and the cylindrical piece is assembled so as to correspond to the deepened mounting groove. Stopping force This means that it is strongly locked to this bulging part, and by the locking of the locking ridge to this bulging part, the fitting of the leg to the main body can be assembled. Will be very strong.
こ のよ う に、 脚体は、 底部の球弧面状 と な っ た外周 面に嵌め込みに よ り 外装組付けさ れ る ので、 場本体の 内圧が大 き く な つ て も、 こ の大き く な つ た内圧を脚体 が支え るので、 内圧に よ り 底部が大 き く 膨出変形す る こ と力 な い。  As described above, since the legs are mounted on the outer surface by fitting into the spherical outer surface of the bottom at the bottom, even if the internal pressure of the field main body becomes large, the legs can be mounted. The legs support the increased internal pressure, so there is no force to bulge and deform the bottom greatly due to the internal pressure.
ま た、 脚筒片の下端緣が底部の下端縁よ り も、 常に 下位に位置す るので、 こ の脚筒片の下端緣が璦体の脚 部を提供す る こ と にな り、 こ の脚筒片が提供す る 脚部 は、 底部の膨出変形に関わ り な く、 常に一定 し た形態 を維持 して、 一定 し た 自 立機能を発揮す る。  Also, since the lower end of the leg tube is always located below the lower edge of the bottom, the lower end of the leg tube provides a single leg. The leg provided by this leg tube piece exhibits a constant self-sustaining function, always maintaining a constant shape, regardless of the bulging deformation of the bottom.
さ ら に、 璦本体 と は别体物であ る 脚体が脚部を提供 す る ので、 取 り 落 と し た際に璦本体の底部に衝撃が直 接作用す る こ と がな く、 常に脚体が ク ッ シ ョ ン体 と し て機能す る ので、 壜本体を ア ク リ ロ ニ ト リ ル樹脂で成 形し た場合で も、 底部の耐衝擎性の髙ぃ璦体を得る こ と がで き る。 In addition, the main body is a separate body, and the legs provide the legs. When the bottle is dropped, the impact does not act directly on the bottom of the main unit, and the legs always function as a cushion. Even if it is formed of acrylonitrile resin, it is possible to obtain a solid body having impact resistance at the bottom.

以下、 本発明 の一実施例を、 図面を参照 しなが ら説 明する。  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
第 1 図 にお いて、 1 は 2 軸延伸ブロ ー成形さ れた合 成樹脂製の璦本体で、 こ の埵本体 1 の胴部 2 下端に連 続して 一体に成形さ れた底部 3 は、 その中央部を 内方 に陥没さ せて 凹部 6 と す る こ と に よ り、 その周囲 に従 来脚部 と し て機能 し て い た部分を形成して い る。  In FIG. 1, 1 is a biaxially stretched blow molded synthetic resin main body, and a bottom 3 formed integrally with the lower end of the body 2 of the main body 1. The central part is depressed inward to form a concave part 6, thereby forming a part which has functioned as a conventional leg part around the concave part 6.
(以下、 第 2 図参照 ) 底部 3 の球弧面状 と な っ た外 周面、 すな わち胴部 2 と の連設箇所 に近い部分 には、 縦幅が広い組付 け凹溝 4 が陥没周設さ れて い る力 こ の組付け凹溝 4 は下方に い く に従っ て その溝深さ を増 大させて 形成さ れて い る。 こ のため、 組付け凹溝 4 の 下側溝縁に は、 比較的突出高さ の大 き い膨出部 5 が付 形さ れる こ と にな る。 こ の璦本体 1 に対 して、 脚体 7 は、 全体が直線短円 筒形状を し て い て、 上半部分であ る 組付 き筒片 9 の内 周面であ る組付き球弧面 1 0 は、 組付け凹溝 4 の溝底 面 と 同 じ曲率半径の球弧面 と な っ て お り、 こ の組付 き 球弧面 1 0 を形成 して い る組付 き 筒片 9 の内周面下端 には、 組付け凹溝 4 の下端緣に係止す る係止条 1 1 が 突条設さ れて い る。 (Refer to Fig. 2 below.) The bottom 3 has an arcuate outer peripheral surface, that is, a portion close to the place where the bottom 3 is connected to the body 2 has a wide vertical groove. The force at which the recess 4 is provided around the depression. The mounting groove 4 is formed by increasing the depth of the groove as it goes down. For this reason, a bulging portion 5 having a relatively large protruding height is formed on the lower groove edge of the assembling concave groove 4. In contrast to the main body 1, the leg 7 has a straight short cylindrical shape as a whole, and a mounting ball which is an inner peripheral surface of the mounting cylinder piece 9 which is an upper half portion. The arc surface 10 is a spherical arc surface having the same radius of curvature as the groove bottom surface of the assembling concave groove 4, and the assembling forming the assembling spherical arc surface 10 is as follows. At the lower end of the inner peripheral surface of the tube piece 9, a locking ridge 11 is formed to protrude from the lower end の of the mounting groove 4.
こ の ため、 脚体 7 の内周面には、 組付き 筒片 9 と脚 筒片 8 と の境界部分に段部が形成さ れる こ と にな り、 脚体 7 が底部 3 に嵌め込み組付け さ れた際に、 膨出部 5 がその組付けの邪魔 と な ら な い よ う に して い る。  For this reason, a step is formed on the inner peripheral surface of the leg 7 at the boundary between the assembled cylinder piece 9 and the leg cylinder piece 8, and the leg 7 is fitted into the bottom 3 and assembled. When attached, the bulging portion 5 does not interfere with the assembly.
係止条 1 1 は、 尖頭状に突出 し た断面構造 と な っ て い る ので、 比較的弾性変形し易い構造 と な っ て お り、 ま た組付 き球弧面 1 0 は、 上方に拡がっ たテーパー面 と な っ て い る ので、 脚体 7 を底部 3 に嵌合組付けす る 際には、 こ の組付 き球弧面 1 0 がガイ ド面 と な っ て璦 本体 1 と 脚体 7 と を組付 き相互位置 に正 し く 案内 し、 次いで強引な押 し込み力 に よ り、 係止条 1 1 が弾性変 形 し て膨出部 5 を乗り 越えて璦本体 1 に対す る脚体 7 の嵌め込み組付けが達成さ れる。  Since the locking ridge 11 has a pointed protruding cross-sectional structure, it has a structure that is relatively easily elastically deformed. When the leg 7 is fitted and assembled to the bottom part 3, the spherical arc surface 10 to be assembled becomes a guide surface when the leg 7 is fitted to the bottom 3. The main body 1 and the leg 7 are assembled and guided correctly to each other, and then, by a forcible pushing force, the locking strip 11 is elastically deformed and rides over the bulging portion 5.脚 The fitting of the leg 7 to the main body 1 is achieved.
底部 3 に組,付け られた脚体 7 は、 その係止条 1 1 の 膨出部 5 に対する係止に よ り、 壜本体 1 に対する組付 き を強固 に保持する。  The legs 7 assembled and attached to the bottom 3 firmly hold the assembly to the bottle body 1 by the engagement of the engagement strips 11 with the bulging portion 5.
こ の脚体 7 は、 耐衝擊性の萵ぃ合成樹脂材料で成形 さ れて お り、 場本体 1 を ア ク リ ロ ニ ト リ ル樹脂で成形 し た場合で も、 璦本体 1 の底部 3 を外部か ら の衝擊に 対 し て充分に保護 して い る。 The legs 7 are made of a shock-resistant high-strength synthetic resin material, and the field body 1 is made of an acrylonitrile resin. Even in this case, the bottom 3 of the main body 1 is sufficiently protected against impact from the outside.
本発明 は、 上記し た構成 と な っ て い る ので、 以下に 示す効果を奏す る。  Since the present invention has the above-described configuration, it has the following effects.
脚体は、 璦本体の最大外径部分で あ る胴部の外径 と ほぼ等 し い外径の直線短円筒形状を し、 こ の短円筒下 位の下端面を脚面 と す る ので、 埕体を起立保持す る た めの底面積が大 き く な り、 こ れに よ り ¾体の起立姿勢 を安定 して保持で き る。  The leg has a straight short cylindrical shape whose outer diameter is almost equal to the outer diameter of the trunk, which is the largest outer diameter of the main body.The lower end of the lower part of this short cylinder is used as the leg surface. The base area for holding and standing the body is increased, and the standing posture of the body can be stably held.
脚体の高さ は、 中央部分を内方に陥没湾曲 さ せ た底 部よ り も わずかに大き いだ けであ る ので、 縦長な璦本 体の高さ に比べて、 その高さが充分に小さ く、 こ の た め瑷体全体の外観に与え る脚体の影響を小さ く す る こ とがで き る。  The height of the legs is only slightly larger than the bottom with the central part depressed inward and curved, so that the height is higher than the height of the vertically long body. It is small enough to reduce the effect of the legs on the overall appearance of the body.
脚体は、 底部外周面に嵌め込み組付けさ れて い る の で、 壜本体内の内圧に よ る 底部の大 き な不正膨出変形 の発生を防止す る こ とがで き、 こ れに よ り 中央部分を 内方に反転陥没させ た構造の底部を有す る璦本体の耐 内圧程度を充分に高め る こ とがで き る。  Since the legs are fitted and assembled on the outer peripheral surface of the bottom, it is possible to prevent the occurrence of large illegal bulging deformation of the bottom due to the internal pressure in the bottle body. As a result, it has a bottom with a structure in which the central portion is inverted and depressed inward. The internal pressure resistance of the main body can be sufficiently increased.
場本体に対す る脚体の組付けは、 単純な嵌め込みに よ り 達成さ れるので、 壜本体と脚体 と の組付け操作が 簡単であ り、 かつ両者の組付けは両者の対向部分の相 互案内 に よ り 達成さ れる ので、 正確 に達成さ れる。  Assembling of the legs to the container body is achieved by simple fitting, so that the assembling operation of the bottle body and the legs is easy, and the assembling of both is performed at the opposing parts of the two. It is achieved accurately because it is achieved by mutual guidance.
脚体を、 耐衝撃性が高 く ク ッ シ ョ ン作用 のあ る合成 樹脂材料で成形す る こ と に よ り、 壜本体の底部を外部 か らの衝撃に対 して保護する こ とがで き、 こ れに よ り 耐衝擎性の低い材料、 例 えばア ク リ ロ ニ ト リ ル樹脂で 璦本体を成形 し た場合で も、 取 り 落 し に よ る衝擊等に 強い瑷体を得る こ とがで き る。 The bottom of the bottle body is made external by molding the legs with synthetic resin material with high impact resistance and cushioning action. It can protect against impacts from the body, which means that even if the main body is made of a material with lower impact resistance, for example, acrylonitrile resin However, it is possible to obtain a strong body against impacts caused by dropping.
