Description

本発明は、ガラス製のコップ胴体と、樹脂製の底体とを備える飲料容器に関する。   The present invention relates to a beverage container provided with a glass cup body and a resin bottom body.

従来の飲料容器の一例としては、ガラス製のコップ胴体の下側開口端部にパッキンを介して樹脂製の底体を配置し、下側開口端部にナットを締め付けることにより、コップ胴体と底体を連結するものが知られている(特許文献1)。   As an example of a conventional beverage container, a resin bottom body is disposed through a packing at the lower opening end of a glass cup body, and a nut is tightened on the lower opening end to thereby fix the cup body and the bottom. What connects a body is known (patent document 1).

特開2014−180438号公報JP 2014-180438 A

ところでこの飲料容器は、ナットを螺合させることによって、部品を一体化する構成を採用しているので、部品同士の間(ガラスと樹脂との境界部分等)に僅かな隙間が形成される。この僅かな隙間は、飲料容器を洗浄した時の水分が侵入する通路となり、長期間に亘って使用していると、隙間に汚れが付着するおそれがある。したがって隙間に汚れが付着しないようにするには、定期的にナットを外して飲料容器を分解し、各部品を洗うことが望ましい。   By the way, since this drink container employ | adopts the structure which integrates components by screwing a nut together, a slight clearance gap is formed between components (border part of glass and resin, etc.). The slight gap becomes a passage through which moisture enters when the beverage container is washed. If the beverage container is used for a long period of time, dirt may adhere to the gap. Therefore, in order to prevent dirt from adhering to the gap, it is desirable to periodically remove the nut, disassemble the beverage container, and wash each part.

しかしながら飲料容器を分解するのは煩雑であり、できるだけ手間をかけることなく清潔な状態で飲料容器を使用できることが望まれる。本発明は上記実情を考慮してなされたもので、その目的はガラスと樹脂との境界部分に汚れが付着しにくい飲料容器を開発することである。   However, it is complicated to disassemble the beverage container, and it is desired that the beverage container can be used in a clean state with as little effort as possible. The present invention has been made in view of the above circumstances, and an object of the present invention is to develop a beverage container in which dirt does not easily adhere to the boundary between glass and resin.

本発明者は、ガラス製のコップ胴体と、樹脂製の底体をインサート成形により、一体化できないかと考えた。そして金型内にあらかじめコップ胴体を挿入しておき、底体に相当する部分をキャビティ(空間部)としておけば、インサート成形時の溶融樹脂により底体を後から形成できるのではないか、と考え、試作を行った。そこで問題となったのが、ガラス製品は、寸法の成形誤差を小さくするのが非常に難しいことである。インサート成形をするには、金型内にあらかじめコップ胴体を挿入して位置決めしておく必要がある。つまり金型の内面に隙間なく一致するような寸法精度の高いコップ胴体を用いる必要がある。しかしながらコップ胴体(ガラス製品)を量産すると、インサート成形には用いることのできない程度の寸法精度の低い製品が多くなり、良品率が悪くなる。   The inventor considered whether a glass cup body and a resin bottom body could be integrated by insert molding. And if the cup body is inserted in the mold in advance and the portion corresponding to the bottom body is set as a cavity (space part), the bottom body can be formed later by molten resin at the time of insert molding. I thought and made a prototype. Thus, the problem is that it is very difficult to reduce the dimensional molding error of glass products. In order to perform insert molding, it is necessary to insert and position the cup body in advance in the mold. In other words, it is necessary to use a cup body with high dimensional accuracy that matches the inner surface of the mold without any gap. However, when a cup body (glass product) is mass-produced, the number of products with low dimensional accuracy that cannot be used for insert molding increases, and the yield rate decreases.

より具体的に言えば、例えば円筒形状のコップ胴体をブロー成形により製造すると、真円度の高いものを製造したいにも関わらず、真円度の低いもの(極端に言えば楕円状のもの)が製造されることがある。このような真円度の低いコップ胴体は、金型に挿入することができなかったり、金型に挿入できても、コップ胴体自体を金型に接触させなければならず、型締め時に破損したりすることがある。   More specifically, for example, when a cylindrical cup body is manufactured by blow molding, a product having a low roundness (in an extreme case, an elliptical shape) even though it is desired to manufacture a product having a high circularity. May be manufactured. Such a cup body with low roundness cannot be inserted into the mold, or even if it can be inserted into the mold, the cup body itself must be in contact with the mold, and it is damaged when the mold is clamped. Sometimes.

またインサート成形ではなく、圧入する組み立て方式も試してみた。詳しく言えば、次の(1)、(2)の手順通りである。(1)ガラス製のコップ胴体をブロー成形により製造し、樹脂製の底体を射出成形により製造する。(2)底体を加熱してある程度柔らかくしてから、コップ胴体の下側開口端部に底体を嵌合するように圧入し、飲料容器を組み立てる。以上の(1)、(2)の手順で組み立てると、圧入直後は、飲料容器の外観は全く問題のない良品の状態となっている。しかしながら底体が冷却されて常温になると、コップ胴体が破損することがあった。この原因は、コップ胴体がガラス製であることからその下側開口端部の真円度が底体に比べて低くなり易いことによるものと考えられる。つまり、圧入直後は底体が下側開口端部の形状に合わせて変形していたのだが、冷却されて常温になる過程で底体は徐々に固くなりつつ収縮し、最終的にはその収縮に下側開口端部が耐え切れなくなって、下側開口端部つまりコップ胴体が破損するに至ったものと考えられる。   We also tried an assembly method that uses press-fitting instead of insert molding. If it says in detail, it is as the procedure of following (1) and (2). (1) A glass cup body is manufactured by blow molding, and a resin bottom body is manufactured by injection molding. (2) After the bottom body is heated and softened to some extent, the bottom body is press-fitted to fit into the lower opening end of the cup body, and a beverage container is assembled. When assembled according to the above procedures (1) and (2), the appearance of the beverage container is in a state of non-defective product without any problem immediately after press-fitting. However, when the bottom body is cooled to room temperature, the cup body may be damaged. This is considered to be because the roundness of the lower opening end of the cup body is likely to be lower than that of the bottom body because the cup body is made of glass. In other words, the bottom body was deformed according to the shape of the lower opening end immediately after the press-fitting, but in the process of cooling to room temperature, the bottom body gradually shrinks while becoming harder and eventually shrinks. It is considered that the lower opening end portion could not endure, and the lower opening end portion, that is, the cup body was damaged.

このような問題を解決するために、本発明は次の構成を採用することにした。本発明の飲料容器は、ガラス製のコップ胴体と、樹脂製の底体と、コップ胴体と底体との境界に充填されて双方を一体化している樹脂製の固着部と、で構成され、コップ胴体は底のない筒状であって、途中の段差面を境として上方の胴部と、下方の下側開口端部と、に区画されており、下側開口端部は胴部よりも小径としてあり、底体は、下側開口端部の下端面を載せる内リングと、内リングから下方に延長する周壁部と、周壁部の底側を塞ぐ底板部と、内リングよりも下方において周壁部から半径方向外側に張り出す外鍔部と、下側開口端部の外周面を包囲する外リングと、外リングと内リングとを接合する接合桟と、で構成され且つこれらを一体成形したものであり、内リングと外鍔部は上下に離れて配置してあり、且つ外鍔部の外縁は、内リングの外縁よりも半径方向外側に位置しており、接合桟は、外リングと内リングを互いの周方向に間隔をあけて接合しており、且つ接合桟は、外リングの外周部よりも半径方向内側に配置してあり、固着部は、外リングと外鍔部との間に形成される空間部を埋めるように充填してあり、下側開口端部および接合桟は固着部で被覆され、コップ胴体と底体との抜け止めのため、下側開口端部の形状を下端に向けて外径が徐々に大きくなるテーパー状とするか、または下側開口端部の外周面と固着部の内周面に互いに嵌合する凹部と凸部を形成してあることを特徴とする。 In order to solve such a problem, the present invention adopts the following configuration. The beverage container of the present invention is composed of a glass cup body, a resin bottom body, and a resin fixing portion that is filled at the boundary between the cup body and the bottom body and integrates both, The cup body is cylindrical with no bottom, and is divided into an upper body part and a lower opening end part below, with a step surface in the middle as a boundary, and the lower opening part part is lower than the body part. The bottom body has an inner ring on which the lower end surface of the lower opening end is placed, a peripheral wall portion extending downward from the inner ring, a bottom plate portion closing the bottom side of the peripheral wall portion, and a lower portion than the inner ring. Consists of an outer flange portion that projects radially outward from the peripheral wall portion, an outer ring that surrounds the outer peripheral surface of the lower opening end portion, and a joining bar that joins the outer ring and the inner ring, and these are integrally molded The inner ring and the outer flange portion are arranged apart from each other in the vertical direction, and the outer edge of the outer flange portion is It is located radially outward from the outer edge of the inner ring, and the joining bar joins the outer ring and the inner ring at intervals in the circumferential direction, and the joining bar is from the outer periphery of the outer ring. Also, the fixing portion is filled so as to fill a space formed between the outer ring and the outer flange portion, and the lower opening end and the joining bar are fixing portions. In order to prevent the cup body and the bottom body from coming off, the shape of the lower opening end is tapered so that the outer diameter gradually increases toward the lower end, or the outer peripheral surface of the lower opening end A concave portion and a convex portion that are fitted to each other are formed on the inner peripheral surface of the fixing portion.

仮に、接合桟の内周側だけに固着部が形成されるならば、接合桟が視認されるようになり、体裁が良くない。このような不都合を回避するため、接合桟は、外リングの外周部よりも半径方向内側に配置し、接合桟の内周側と外周側の両方を固着部で被覆する。 If the fixing portion is formed only on the inner peripheral side of the joining bar, the joining bar can be visually recognized, and the appearance is not good. In order to avoid such an inconvenience , the joining bar is arranged radially inside the outer peripheral part of the outer ring, and both the inner peripheral side and the outer peripheral side of the joining bar are covered with the fixing part.

コップ胴体の内側に液体を収容する関係上、内リングと下側開口端部との間から液漏れがしないようにするために、内リングは下側開口端部の下端面にできるだけ強く密接していることが望ましい。そこで底体は、内リングから下方に延長する周壁部と、周壁部の底側を塞ぐ底板部と、内リングよりも下方において周壁部から半径方向外側に張り出す外鍔部と、を備えるものとする。したがって内リングと外鍔部は上下に離れており、そこに固着部が入り込むことで内リングが押し上げられ、下側開口端部の下端面に強く密接する。 In order to prevent liquid from leaking between the inner ring and the lower opening end, the inner ring is as close as possible to the lower end surface of the lower opening end. It is desirable that So the bottom body includes a peripheral wall extending from the inner ring downward, a bottom plate closing the bottom side of the peripheral wall portion, an outer collar portion protruding radially outward from Oite peripheral wall portion below the inner ring Shall be provided. Therefore, the inner ring and the outer flange portion are separated from each other in the vertical direction, and the inner ring is pushed up when the fixing portion enters therein, and is strongly in close contact with the lower end surface of the lower opening end portion.

外リングの外径と胴部の段差面の外径との関係は問わないし、内リングの内径と下側開口端部の下端面の内径との関係も問わず、たとえば外リングの外径を胴部の段差面の外径以下にしたり、内リングの内径を下側開口端部の下端面の内径以上にしたりしても良い。しかしこの場合、コップ胴体のために外リングと内リングを金型内で位置決めする際に、内外リングをその貫通方向に正確に位置決めしなければ、下側開口端部の付近でコップ胴体と金型とが接触するおそれがあり、それを防ぐには次のようにすることが望ましい。
すなわち外リングの外径は胴部の段差面の外径よりも大きく、内リングの内径は下側開口端部の下端面の内径よりも小さくすることである。
Regardless of the relationship between the outer diameter of the outer ring and the outer diameter of the stepped surface of the body portion, and the relationship between the inner diameter of the inner ring and the inner diameter of the lower end surface of the lower opening end, for example, the outer diameter of the outer ring The inner diameter of the stepped surface of the body portion may be made smaller than the outer diameter, or the inner diameter of the inner ring may be made larger than the inner diameter of the lower end surface of the lower opening end. However, in this case, when positioning the outer ring and the inner ring in the mold for the cup body, unless the inner and outer rings are positioned accurately in the penetrating direction, the cup body and the mold are located near the lower opening end. In order to prevent the mold from coming into contact, it is desirable to do the following.
That is, the outer diameter of the outer ring is larger than the outer diameter of the stepped surface of the body portion, and the inner diameter of the inner ring is made smaller than the inner diameter of the lower end surface of the lower opening end.

本発明の飲料容器によれば、固着部によりコップ胴体と底体を一体化するので、従来のような螺合する構成の場合に比べて隙間は出来ず、その結果、汚れが付着しづらいものと言える。またインサート成形時に金型内においてコップ胴体をその半径方向に位置決めする場合に、コップ胴体の下側開口端部の半径方向を外リングと内リングにより位置決めすることができるので、型締め時には樹脂製の両リングが金型に接触することになり、インサート成形時にガラス製のコップ胴体が破損するのを防止することができる。 According to the beverage container of the present invention, since the cup body and the bottom body are integrated by the fixing portion , there is no gap as compared with the conventional screwing configuration, and as a result, dirt is difficult to adhere. It can be said. When the cup body is positioned in the radial direction in the mold during insert molding, the radial direction of the lower opening end of the cup body can be positioned by the outer ring and the inner ring . Both rings come into contact with the mold, and the glass cup body can be prevented from being damaged during insert molding.

さらに接合桟は、外リングの外周部よりも半径方向内側に配置することで、外リングの下側では、接合桟が固着部で隠蔽される。そのため、コップ胴体の下方に外リングと固着部が帯状に配置される形態となり、体裁の良いものとなる。 Furthermore, the joining bar is arranged radially inward of the outer peripheral part of the outer ring, so that the joining bar is concealed by the fixing part below the outer ring. Therefore, the outer ring and the fixing portion are arranged in a band shape below the cup body, and the appearance is good.

しかも、内リングと外鍔部を上下に離れて配置することで、固着部の成形時、キャビティに充填された溶融樹脂が内リングと外鍔部との間に入り込み、その圧力により、内リングが下側開口端部の下端面に強く密接し、液漏れを防ぐ。なお固着部の成形時は、飲み口側(上端面)からも位置決めを行うため、この密接が実現する。 Moreover , by arranging the inner ring and the outer flange portion apart from each other in the vertical direction, the molten resin filled in the cavity enters between the inner ring and the outer flange portion at the time of molding the fixing portion, and the inner ring is caused by the pressure. Strongly adheres to the lower end surface of the lower opening end to prevent liquid leakage. In addition, since the positioning is performed also from the drinking mouth side (upper end surface) at the time of forming the fixing portion, this close contact is realized.

しかも外リングの外径を胴部の段差面の外径よりも大きく、内リングの内径を下側開口端部の下端面の内径よりも小さくした飲料容器によれば、金型のうち外リングに接触する部分と、内リングに接触する部分の貫通方向の寸法を、対応する内外リングの寸法よりも長いものを用いても、金型の当該接触する部分にコップ胴体が接触するのを防止することができる。   In addition, according to the beverage container in which the outer diameter of the outer ring is larger than the outer diameter of the stepped surface of the body portion and the inner diameter of the inner ring is smaller than the inner diameter of the lower end surface of the lower opening end portion, Prevents the cup body from coming into contact with the parts of the mold that come into contact with each other, even if the dimension in the penetrating direction of the part that contacts the inner ring and the part that contacts the inner ring is longer than the corresponding inner and outer ring dimensions. can do.

本発明の第一実施形態の飲料容器1は図1、図2に示すように、筒状(より詳しくは円筒状)のコップ胴体2と、コップ胴体2の下端を塞ぐ底部材4Aと、底部材4Aをコップ胴体2に固着する固着部6を主として構成される。また第一実施形態の飲料容器1は、インサート成形による成型品であり、コップ胴体2と底部材4Aとを固着部6により分解不能に一体化したものである。   As shown in FIGS. 1 and 2, the beverage container 1 according to the first embodiment of the present invention includes a cylindrical (more specifically, cylindrical) cup body 2, a bottom member 4 </ b> A that closes the lower end of the cup body 2, and a bottom portion. The fixing portion 6 for fixing the material 4A to the cup body 2 is mainly configured. Moreover, the beverage container 1 of 1st embodiment is a molded article by insert molding, and integrates the cup body 2 and the bottom member 4A by the adhering part 6 so that it cannot be disassembled.

コップ胴体2は、ガラス製のインサート部品であり、たとえばブロー成形により形成される。またコップ胴体2は、上下方向に貫通する筒状であって、その下端部を上側部分よりも外径を段差状に小さくした形状としたものである。より詳しく言えばコップ胴体2は、その下端部である下側開口端部24を底部材4Aに固着する部分とし、下側開口端部24よりも上側を胴部22とする。つまりコップ胴体2は、胴部22と下側開口端部24とから構成され、胴部22と下側開口端部24とは筒状(より詳しくは円筒状)の貫通方向に連続している。   The cup body 2 is an insert part made of glass, and is formed by, for example, blow molding. The cup body 2 has a cylindrical shape penetrating in the vertical direction, and has a lower end portion whose outer diameter is made smaller than the upper portion in a stepped shape. More specifically, the cup body 2 has a lower opening end 24 that is a lower end portion thereof as a portion that is fixed to the bottom member 4A, and a portion above the lower opening end 24 is referred to as a body portion 22. That is, the cup body 2 includes a body portion 22 and a lower opening end portion 24, and the body portion 22 and the lower opening end portion 24 are continuous in a cylindrical (more specifically, cylindrical) penetration direction. .

胴部22は、外径に関して、その下端部を下側開口端部24に比べて明らかに大径とし、それゆえ胴部22の下端と下側開口端部24の上端との間には胴部22の下端から半径方向内側へ段差状に凹んだ環状(より詳しくは円環状)の段差面22aが形成されている。したがってコップ胴体2の外周面は、下側開口端部24の外周面と、胴部22の外周面と、段差面22aとから構成されている。段差面22aは水平面、より詳しくは半径方向内側へ向かって徐々に下方へ向かう緩やかな斜面となっている。   The barrel 22 has a lower end with respect to the outer diameter that is clearly larger than the lower opening end 24, and therefore the barrel 22 is located between the lower end of the barrel 22 and the upper end of the lower opening end 24. An annular (more specifically, annular) step surface 22a is formed that is recessed in a step shape from the lower end of the portion 22 inward in the radial direction. Therefore, the outer peripheral surface of the cup body 2 is composed of the outer peripheral surface of the lower opening end 24, the outer peripheral surface of the body portion 22, and the step surface 22a. The step surface 22a is a horizontal plane, more specifically, a gentle slope gradually going downward inward in the radial direction.

下側開口端部24はその下端に向かって徐々に外径及び内径が小さくなるテーパー形状をしている。また下側開口端部24の下端面24aは、水平面、より詳しくは段差面22aに比べて精度の高い水平面となっている。なお下端面24aは、切削加工することによって所望の精度の水平面に仕上げられる。   The lower opening end 24 has a tapered shape in which the outer diameter and inner diameter gradually decrease toward the lower end. Further, the lower end surface 24a of the lower opening end 24 is a horizontal plane, more specifically, a horizontal plane with higher accuracy than the stepped surface 22a. The lower end surface 24a is finished into a horizontal plane with a desired accuracy by cutting.

底部材4Aは、1つの樹脂製(より詳しくは合成樹脂製品)のインサート部品であり、たとえば射出成形により一体成形される。また底部材4Aは、下側開口端部24に取り付けられるリング5と、リング5の下側を塞ぐ底体4とを備える。   The bottom member 4A is an insert part made of one resin (more specifically, a synthetic resin product), and is integrally molded by, for example, injection molding. The bottom member 4 </ b> A includes a ring 5 attached to the lower opening end 24 and a bottom body 4 that closes the lower side of the ring 5.

リング5は、胴部22の段差面22aに重ね合わせる外リング52と、下側開口端部24の下端面24aに重ね合わせる内リング54と、外リング52と内リング54とを接合するリング接合部56を備える。   The ring 5 includes an outer ring 52 that overlaps the stepped surface 22 a of the body 22, an inner ring 54 that overlaps the lower end surface 24 a of the lower opening end 24, and a ring joint that joins the outer ring 52 and the inner ring 54. A unit 56 is provided.

外リング52及び内リング54は、いずれも円環状の板である。また外リング52の外径は段差面22aの外径よりも大きく、外リング52の内径は段差面22aの内径、すなわち下側開口端部24の上端外径よりも大きくなっている。一方、内リング54の内径は下側開口端部24の下端面24aの内径よりも小さく、内リング54の外径は当該下端面24aの内径よりも大きく、且つ当該下端面24aの外径よりも小さくなっている。ちなみにコップ胴体2の真円度が低いものであっても、段差面22a及び下側開口端部24の下端面24aと、外リング52及び内リング54とが、上記した半径方向の関係を保てるように、外リング52及び内リング54の半径方向の寸法は設計されている。なお外リング52の上面は水平面、より詳しくは段差面22aに対応させた緩やかな斜面であり、内リング54の上面は水平面、より詳しくは下端面24aに対応させた水平面となっている。外リング52と内リング54は上下に離れた位置関係にあり、これら内外リング54,52を接合するのが、リング接合部56である。   Both the outer ring 52 and the inner ring 54 are annular plates. The outer diameter of the outer ring 52 is larger than the outer diameter of the step surface 22a, and the inner diameter of the outer ring 52 is larger than the inner diameter of the step surface 22a, that is, the upper end outer diameter of the lower opening end 24. On the other hand, the inner diameter of the inner ring 54 is smaller than the inner diameter of the lower end surface 24a of the lower opening end 24, the outer diameter of the inner ring 54 is larger than the inner diameter of the lower end surface 24a, and the outer diameter of the lower end surface 24a. Is also getting smaller. Incidentally, even if the roundness of the cup body 2 is low, the step surface 22a and the lower end surface 24a of the lower opening end 24, the outer ring 52 and the inner ring 54 can maintain the above-described radial relationship. As such, the radial dimensions of the outer ring 52 and the inner ring 54 are designed. The upper surface of the outer ring 52 is a horizontal plane, more specifically, a gentle slope corresponding to the step surface 22a, and the upper surface of the inner ring 54 is a horizontal plane, more specifically, a horizontal plane corresponding to the lower end surface 24a. The outer ring 52 and the inner ring 54 are positioned apart from each other in the vertical direction, and the ring joint 56 joins the inner and outer rings 54, 52.

リング接合部56は、下側開口端部24の外周面を部分的に(より詳しくは格子状に)覆うもので、外リング52と内リング54を互いの周方向に間隔(より詳しくは等間隔)をあけて接合する複数の接合桟56aより構成される。接合桟56aは、L字形状であって、上下方向に延長する縦桟部56bと、半径方向に延長する横桟部56cとが屈曲する形で連続するものである。   The ring joint 56 partially covers the outer peripheral surface of the lower opening end 24 (more specifically, in a lattice shape), and the outer ring 52 and the inner ring 54 are spaced apart from each other in the circumferential direction (more specifically, etc.). It is composed of a plurality of joining bars 56a that are joined at intervals. The joining beam 56a is L-shaped, and is continuous in a shape in which a vertical beam 56b extending in the vertical direction and a horizontal beam 56c extending in the radial direction are bent.

横桟部56cは内リング54の外周から半径方向外側に延長し、コップ胴体2の下端面24aの外周部に接する。つまり横桟部56cは、その上面を水平面とし、内リング54の上面と面一に連続するものである。また横桟部56cの下面は半径方向外側へむかうにつれて徐々に上昇する斜面としてある。なお横桟部56cは上面視すると(図2(c)参照)、半径方向の内側から外側へ向かうにつれて円周方向の幅が狭くなる形状である。   The horizontal crosspiece 56c extends radially outward from the outer periphery of the inner ring 54 and contacts the outer peripheral portion of the lower end surface 24a of the cup body 2. That is, the horizontal crosspiece 56c has a top surface that is a horizontal plane and is continuous with the top surface of the inner ring 54. The lower surface of the horizontal crosspiece 56c is a slope that gradually rises toward the outside in the radial direction. When viewed from the top (see FIG. 2C), the horizontal crosspiece 56c has a shape in which the width in the circumferential direction becomes narrower from the inner side to the outer side in the radial direction.

一方、縦桟部56bは横桟部56cの先端部(半径方向の外側端部)から外リング52の内周部に達するまで上方に延長し、下側開口端部24の外周面を半径方向にわずかな隙間をあける状態で覆う。より詳しくは、縦桟部56bの内周面は外リング52の内周面に連続する面となっており、縦桟部56bの外周面は外リング52の下面と交差する面となっている。つまり縦桟部56bの外周面の上端は、外リング52の下面の外周よりも半径方向内側に位置している。このような縦桟部56bを含むリング接合部56の下側に底体4が連続している。   On the other hand, the vertical beam portion 56b extends upward from the front end portion (radially outer end portion) of the horizontal beam portion 56c until it reaches the inner peripheral portion of the outer ring 52, and the outer peripheral surface of the lower opening end portion 24 extends in the radial direction. Cover with a slight gap. More specifically, the inner peripheral surface of the vertical beam portion 56 b is a surface that is continuous with the inner peripheral surface of the outer ring 52, and the outer peripheral surface of the vertical beam portion 56 b is a surface that intersects the lower surface of the outer ring 52. . That is, the upper end of the outer peripheral surface of the vertical beam portion 56 b is located radially inward from the outer periphery of the lower surface of the outer ring 52. The bottom body 4 is continuous to the lower side of the ring joint portion 56 including the vertical beam portion 56b.

底体4は、コップ胴体2の下側開口端部24を塞ぐ底としての本来の機能と、内部に液体を外部から注入可能とする機能を有する。より詳しくは底体4は、半径方向を二重壁構造とする器状であって、内リング54の下方を塞いでいる。底体4は、内リング54の内周部から下方に延長する周壁部42と、周壁部42の上部であって内リング54に対して下方に間隔をあけた位置において周壁部42からその半径方向外側に張り出す環状の(円環状の)外鍔部44と、外鍔部44の外周部から下方に延長する外壁部46と、周壁部42の底側を塞ぐ底板部48とを備える。   The bottom body 4 has an original function as a bottom that closes the lower opening end 24 of the cup body 2 and a function that allows liquid to be injected into the inside from the outside. More specifically, the bottom body 4 has a container shape having a double wall structure in the radial direction, and closes the lower portion of the inner ring 54. The bottom body 4 has a peripheral wall portion 42 extending downward from the inner peripheral portion of the inner ring 54, and a radius thereof from the peripheral wall portion 42 at a position above the inner ring 54 and spaced downward from the inner ring 54. An annular (annular) outer flange portion 44 projecting outward in the direction, an outer wall portion 46 extending downward from the outer peripheral portion of the outer flange portion 44, and a bottom plate portion 48 closing the bottom side of the peripheral wall portion 42 are provided.

周壁部42はその全高のうち上側に外鍔部44を連続するものである。また周壁部42は、外鍔部44よりも上側部分を、内リング54の周方向の全周に亘って連続する筒状(円筒状)とし、外鍔部44よりも下側部分を、周方向の一部が凹んだ歪な形の筒状としてある。より詳しく言えば外鍔部44よりも下側部分は、周方向の全周のうち大部分を断面円弧状に連続する内側円弧部42aとし、周方向の全周のうち一部(残り部分)を半径方向内側へ陥没する陥没部42bとしたもので、上下方向から視ると(図2(c)(d))、円周の1/4程度を半径方向内側へ向けて断面L字状に屈曲するように陥没させてある。またL字状の陥没部42bの一片には水平方向に貫通する液体流入口42cを備えている。液体流入口42cは円形状であり、その内側には、柔軟な樹脂製からなる弾性体の逆止弁9を着脱可能に取り付けてある。ちなみに逆止弁9は、底体4の外部からノズルを抜き差し可能なものである。そして逆止弁9に差し込んだノズルから液体を飲料容器1内に注ぐことを可能とする。   The peripheral wall portion 42 has a continuous outer flange portion 44 on the upper side of the total height. In addition, the peripheral wall portion 42 has an upper portion with respect to the outer flange portion 44 formed in a cylindrical shape (cylindrical shape) continuous over the entire circumference in the circumferential direction of the inner ring 54, and a lower portion with respect to the outer flange portion 44. It is a distorted cylindrical shape with a part of the direction recessed. More specifically, the lower portion of the outer flange portion 44 is an inner circular arc portion 42a that is continuous in a circular arc shape in the entire circumference in the circumferential direction, and a part (remaining portion) of the entire circumference in the circumferential direction. Is a recessed portion 42b that is recessed inward in the radial direction. When viewed from above and below (FIGS. 2 (c) and (d)), about a quarter of the circumference is directed inward in the radial direction. It is depressed to bend. A piece of the L-shaped depression 42b is provided with a liquid inlet 42c penetrating in the horizontal direction. The liquid inflow port 42c has a circular shape, and an elastic check valve 9 made of a flexible resin is detachably attached to the inside thereof. Incidentally, the check valve 9 can be inserted and removed from the outside of the bottom body 4. Then, the liquid can be poured into the beverage container 1 from the nozzle inserted into the check valve 9.

外鍔部44は、その外径を下側開口端部24の下端面24aのそれよりも大きくし、より詳しくは外リング52の外径と同じ程度としてある。外鍔部44と外リング52との上下方向の間には下側開口端部24の外周面に通じる空間部8が形成される。より詳しくは、この空間部8は、上下に離れた外鍔部44と内リング54との間についてはその内周側を周壁部42によって塞がれており、上下に離れた内リング54と外リング52との間についてはリング接合部56の格子形状によって下側開口端部24の外周面及び下端面24aに通じるものとしてある。またこの空間部8は、インサート成形時に溶融樹脂によって満たされる部分であり、その溶融樹脂が最終的に固着部6になる。   The outer flange portion 44 has an outer diameter larger than that of the lower end surface 24 a of the lower opening end portion 24, and more specifically, is approximately the same as the outer diameter of the outer ring 52. A space 8 that communicates with the outer peripheral surface of the lower opening end 24 is formed between the outer flange portion 44 and the outer ring 52 in the vertical direction. More specifically, the space 8 has a space between the outer flange portion 44 and the inner ring 54 that are separated from each other in the vertical direction, and the inner peripheral side thereof is closed by the peripheral wall portion 42. The space between the outer ring 52 and the outer ring 52 leads to the outer peripheral surface and the lower end surface 24a of the lower opening end 24 due to the lattice shape of the ring joint 56. The space 8 is a portion filled with a molten resin at the time of insert molding, and the molten resin finally becomes the fixing portion 6.

外壁部46は、周壁部42の形状(外鍔部44よりも下側部分の形状)に対応させており、内側円弧部42aの外側を半径方向外側に間隔をあけて断面円弧状に覆う外側円弧部46aとし、外側円弧部46aの両端部から陥没部42bの周方向両端部に連続するように半径方向の内側へ向かって延長する部分を一対の板状の延長部46b,46bとするものである。したがって底体4は、円周方向の全周を二重壁構造としたのではなく、円周方向の大部分(周壁部42の陥没部42b以外)を二重壁構造としたものである。   The outer wall portion 46 corresponds to the shape of the peripheral wall portion 42 (the shape of the lower portion than the outer flange portion 44), and is an outer side that covers the outer side of the inner circular arc portion 42a in a circular arc shape with a gap radially outward. The arc portion 46a is a pair of plate-like extension portions 46b and 46b that extend radially inward from both ends of the outer arc portion 46a so as to continue to both ends in the circumferential direction of the depressed portion 42b. It is. Therefore, the bottom body 4 does not have a double wall structure on the entire circumference in the circumferential direction, but has a double wall structure on most of the circumferential direction (other than the recessed portion 42b of the circumferential wall portion 42).

底板部48は、周壁部42の内周全周を塞いでいる。また底板部48の上面は、L字状の陥没部42bのうち液体流入口42cを備える一片から他片へ向けて円周方向に沿って徐々に上昇する傾斜面となっている。これは液体流入口42c側から注入した液体が螺旋状に上昇するようにするためである。このような底板部48を含む底体4とコップ胴体2とを連結するのが、連結部3である。   The bottom plate portion 48 closes the entire inner periphery of the peripheral wall portion 42. The top surface of the bottom plate portion 48 is an inclined surface that gradually rises along the circumferential direction from one piece having the liquid inlet 42c to the other piece in the L-shaped depression 42b. This is because the liquid injected from the liquid inlet 42c side rises spirally. The connecting portion 3 connects the bottom body 4 including the bottom plate portion 48 and the cup body 2.

連結部3は、底部材4Aの一部でもあるリング5と、リング5をコップ胴体2の下側開口端部24に固着する固着部6とを備え、胴部22の段差面22a及び下側開口端部24の下端面24aにリング5を重ね合わせた状態に保持する。   The connecting portion 3 includes a ring 5 that is also a part of the bottom member 4A, and a fixing portion 6 that fixes the ring 5 to the lower opening end 24 of the cup body 2. The ring 5 is held in a state of being superimposed on the lower end surface 24 a of the opening end 24.

固着部6は、リング5と下側開口端部24とをインサート成形により一体化する部分であって、空間部8に対応した形状であって、外リング52と外鍔部44との間において上下方向に延長する環状(円環状)の被覆部62と、被覆部62の下端部から周壁部42に達するまで半径方向内側へ突出する環状(円環状)の内鍔部64とを備える。したがって内鍔部64は固着部6の下端部の口径を狭めるようになっている。   The fixing portion 6 is a portion that integrates the ring 5 and the lower opening end portion 24 by insert molding, and has a shape corresponding to the space portion 8, and is between the outer ring 52 and the outer flange portion 44. An annular (annular) covering portion 62 extending in the vertical direction and an annular (annular) inner collar portion 64 projecting radially inward from the lower end portion of the covering portion 62 until reaching the peripheral wall portion 42 are provided. Therefore, the inner collar portion 64 narrows the diameter of the lower end portion of the fixing portion 6.

被覆部62は、その外周面よりも半径方向内側に(より詳しくは半径方向内周部に)リング接合部56の複数の縦桟部56bを埋設しており、それゆえリング接合部56をその周方向全周に亘って被覆している。また被覆部62は、下側開口端部24の外周面と縦桟部56bの内周面との半径方向の間の隙間にも入り込んでおり、下側開口端部24の外周面に密着している。   The covering portion 62 embeds a plurality of vertical beam portions 56b of the ring joint portion 56 on the inner side in the radial direction from the outer peripheral surface (more specifically, in the inner peripheral portion in the radial direction). The entire circumference is covered. The covering portion 62 also enters a gap between the outer peripheral surface of the lower opening end portion 24 and the inner peripheral surface of the vertical beam portion 56b in the radial direction, and is in close contact with the outer peripheral surface of the lower opening end portion 24. ing.

内鍔部64は、その上部に複数の横桟部56cを埋設すると共に、下側開口端部24の下端面24a及び内リング54の下面、外鍔部44の上面、周壁部42の外周面に密接している。   The inner flange portion 64 has a plurality of horizontal crosspieces 56c embedded in the upper portion thereof, and the lower end surface 24a of the lower opening end 24 and the lower surface of the inner ring 54, the upper surface of the outer flange portion 44, and the outer peripheral surface of the peripheral wall portion 42. Close to.

また固着部6の内周面と下側開口端部24の外周面には互いに嵌合する抜け止め用の凹部7aと凸部7bが形成されている。凹部7aは、下側開口端部24の外周面の半径方向内側に凹んでおり、その位置は下側開口端部24の外周面の下端よりも上側であって、外リング52によって包囲される部分よりも下側の位置である。また凹部7aは環状(円環状)であって、下側開口端部24の外周面の周方向全周に亘って形成されている。凸部7bは、凹部7aの形状に対応して環状(円環状)となっている。   Further, a recess 7a and a protrusion 7b for retaining each other are formed on the inner peripheral surface of the fixing portion 6 and the outer peripheral surface of the lower opening end 24. The recess 7 a is recessed radially inward of the outer peripheral surface of the lower opening end 24, and its position is above the lower end of the outer peripheral surface of the lower opening end 24 and is surrounded by the outer ring 52. It is the position below the part. The recess 7 a is annular (annular) and is formed over the entire circumference of the outer peripheral surface of the lower opening end 24. The convex portion 7b has an annular shape (annular shape) corresponding to the shape of the concave portion 7a.

上記した第一実施形態の飲料容器1は、以下の(1)〜(4)の手順でインサート成形される。
(1)型開き状態にある金型のキャビティにインサート部品(コップ胴体2、底部材4A)を挿入する。
(2)金型を型締めする。そうすると、飲料容器1の深さ方向に関してはコップ胴体2の飲み口側(上端側)と底部材4Aとが外側から位置決めされる。図4では、底部材4Aの底板部48が底側位置決め部材82により位置決めされた状態が示され、飲み口側については図示が省略されている。また飲料容器1の半径方向の内周側に関しては、内リング54の内周側に内側位置決め部材84が挿入されることにより、底部材4Aの内周側だけでなく、コップ胴体2の下側開口端部24の内周側も位置決めされる。飲料容器1の半径方向の外周側に関しては、外リング52の外周面と外鍔部44の外周面に全周に亘って外側位置決め部材86が接触することにより、底部材4Aの外周側だけでなく、コップ胴体2の下側開口端部24の外周側も位置決めされる。なお前記したリング5の半径方向の寸法設計により、同一寸法のリング5を、コップ胴体2の真円度が高いものに限らず、低いものであっても、その下側開口端部24に対して装着できるようになり、リング5と内側及び外側位置決め部材84,86との位置決めも可能となる。
また位置決めすることによって、溶融樹脂を射出するための空間部8が形成される。空間部8は、その上面側を胴部22の段差面22aに重ね合わせた外リング52により形成し、その下面側を外鍔部44により形成し、その半径方向の内周面側を下側開口端部24(外周面及び下端面24a)及び内リング54により形成し、その半径方向の外周面側を外側位置決め部材86により形成している。なお図3(a)には底部材4Aをコップ胴体2に取り付けた状態での外観が示されている。図ではコップ胴体2の外周面に小さな点を多数分布することによって、リング接合部56が下側開口端部24を包囲している状態を明確に示してある。
(3)溶融樹脂を空間部8に射出する。そうすると空間部8が溶融樹脂で充填され、外リング52及び内リング54がコップ胴体2に溶融樹脂の圧力によって強固に押し付けられ、段差面22aと外リング52の上面とが隙間なく密接し、下側開口端部24の下端面24aと内リング54の上面も隙間なく密接する。空間部8に充填された溶融樹脂のうち一部は冷却したときに内鍔部64となり、内鍔部64は外鍔部44と内リング54との間に強固に挟まれることになり、結果的に飲料容器1の内側から液漏れがしないようになる。また溶融樹脂のうち一部は環状の凸部7bとなって、下側開口端部24の凹部7aの周囲を全周に亘って取り囲むことになり、リング5と下側開口端部24とを強固に一体化する。
(4)金型内で十分に冷却されてから型開きがなされ、インサート成型品が取り出される。なおインサート成型品に逆止弁9を取り付けることによって飲料容器1が完成する。また図3(b)に示すように正面視すると、飲料容器1は、コップ胴体2の胴部22の下に外リング52、固着部6がいずれも帯状に配置されている。外リング52及び固着部6は何れも環状であるので、背面、左右側面から見ても、帯状である。そしてその固着部6の下側に外壁部46が配置された形状となり、飲料容器1は体裁の良いものとなっている。たとえば飲料容器1は、ガラス製のコップ胴体2と、樹脂製の底部材4A及び固着部6とを同じ色(透明も含む)とすれば、飲料容器1の外観が統一されたものとなる。なお図1では固着部6と底部材4Aとは別体であるかのように、互いのハッチングパターンを異ならせてあるが、インサート成形によって固着部6と底部材4Aとは一体化される(インサート成形時の固着部6の溶融樹脂の熱により、底部材4Aもその溶融樹脂に接した部分が溶融して一体化される)ので、本来、図1では、底部材4Aと固着部6とを1つのハッチングパターンで示すことが、正確な表現手法である。但し、理解の容易さを考慮してこのような図面の表現を採用してある。図3(b)でも固着部6と底部材4Aとは別体であるかのように境界を水平な実線で明示してあるが、前記した理由により、固着部6と底部材4Aとは一体化されるので、境界を示す水平な実線は、実際の製品の外観には現れ難い。特に、樹脂製の底部材4Aと固着部6とを同じ色にした場合であれば、実際の製品では底部材4Aと固着部6との境界は肉眼では区別しづらい。しかし底部材4Aと固着部6とを異なる色とした場合、より詳しく言えば、たとえば底部材4Aを透明としたうえで、固着部6を形成する溶融樹脂に着色(有色で不透明と)されたものを用いた場合や、あるいは底部材4Aを透明としたうえで、固着部6を不透明(固着部6を形成する溶融樹脂を透明なものにすると共に、固着部6の表面を梨地模様(凹凸のある模様))とした場合であれば、固着部6と底部材4Aとが異なる部材として視認されるので、固着部6が帯状に際立って視認されるようになり、デザイン性の良い仕上がりとなる。
The beverage container 1 of the first embodiment described above is insert-molded by the following procedures (1) to (4).
(1) Insert parts (the cup body 2 and the bottom member 4A) are inserted into the mold cavity in the mold open state.
(2) Clamp the mold. Then, with respect to the depth direction of the beverage container 1, the drinking mouth side (upper end side) of the cup body 2 and the bottom member 4A are positioned from the outside. FIG. 4 shows a state in which the bottom plate portion 48 of the bottom member 4A is positioned by the bottom side positioning member 82, and illustration of the drinking mouth side is omitted. As for the radially inner peripheral side of the beverage container 1, the inner positioning member 84 is inserted into the inner peripheral side of the inner ring 54, so that not only the inner peripheral side of the bottom member 4 </ b> A but also the lower side of the cup body 2. The inner peripheral side of the opening end 24 is also positioned. Regarding the outer peripheral side in the radial direction of the beverage container 1, the outer positioning member 86 is in contact with the outer peripheral surface of the outer ring 52 and the outer peripheral surface of the outer flange portion 44 over the entire periphery, so that only the outer peripheral side of the bottom member 4 </ b> A. The outer peripheral side of the lower opening end 24 of the cup body 2 is also positioned. Note that the ring 5 having the same dimension is not limited to the one with the high roundness of the cup body 2, and the lower opening end 24 is not limited to the one having a low roundness due to the radial dimension design of the ring 5 described above. The ring 5 and the inner and outer positioning members 84 and 86 can be positioned.
Moreover, the space part 8 for injecting molten resin is formed by positioning. The space portion 8 is formed by an outer ring 52 whose upper surface is overlapped with the stepped surface 22a of the body portion 22, its lower surface is formed by the outer flange portion 44, and its radially inner peripheral surface is the lower side. The opening end portion 24 (outer peripheral surface and lower end surface 24 a) and the inner ring 54 are formed, and the outer peripheral surface side in the radial direction is formed by the outer positioning member 86. FIG. 3 (a) shows the appearance of the bottom member 4A attached to the cup body 2. FIG. In the figure, a state where the ring joint 56 surrounds the lower opening end 24 is clearly shown by distributing a large number of small points on the outer peripheral surface of the cup body 2.
(3) The molten resin is injected into the space 8. Then, the space 8 is filled with the molten resin, the outer ring 52 and the inner ring 54 are firmly pressed against the cup body 2 by the pressure of the molten resin, and the stepped surface 22a and the upper surface of the outer ring 52 are in close contact with each other without any gap. The lower end surface 24a of the side opening end portion 24 and the upper surface of the inner ring 54 are also in close contact with each other without a gap. A part of the molten resin filled in the space portion 8 becomes the inner flange portion 64 when cooled, and the inner flange portion 64 is firmly sandwiched between the outer flange portion 44 and the inner ring 54, and as a result Thus, no liquid leaks from the inside of the beverage container 1. Further, a part of the molten resin becomes an annular convex portion 7b and surrounds the entire periphery of the concave portion 7a of the lower opening end 24, and the ring 5 and the lower opening end 24 are separated. Integrate firmly.
(4) The mold is opened after being sufficiently cooled in the mold, and the insert molded product is taken out. The beverage container 1 is completed by attaching the check valve 9 to the insert molded product. When viewed from the front as shown in FIG. 3B, the beverage container 1 has the outer ring 52 and the adhering portion 6 arranged in a band shape under the body portion 22 of the cup body 2. Since both the outer ring 52 and the adhering portion 6 are annular, the outer ring 52 and the adhering portion 6 have a belt shape when viewed from the back and the left and right sides. And it becomes the shape by which the outer wall part 46 was arrange | positioned under the adhering part 6, and the drink container 1 has a good appearance. For example, if the glass cup body 2, the resin bottom member 4A, and the fixing portion 6 have the same color (including transparency), the beverage container 1 has a uniform appearance. In FIG. 1, the hatching patterns are different from each other as if the fixing portion 6 and the bottom member 4 </ b> A are separate, but the fixing portion 6 and the bottom member 4 </ b> A are integrated by insert molding ( Since the portion of the bottom member 4A that is in contact with the molten resin is melted and integrated by the heat of the molten resin of the fixing portion 6 at the time of insert molding, originally the bottom member 4A and the fixing portion 6 in FIG. It is an accurate expression method to indicate the above with one hatching pattern. However, in consideration of ease of understanding, such a drawing is adopted. In FIG. 3B, the boundary is clearly indicated by a horizontal solid line as if the fixing portion 6 and the bottom member 4A are separate from each other. However, for the reasons described above, the fixing portion 6 and the bottom member 4A are integrated. Therefore, the horizontal solid line indicating the boundary hardly appears in the appearance of the actual product. In particular, when the resin bottom member 4A and the fixing portion 6 are made the same color, in the actual product, it is difficult to distinguish the boundary between the bottom member 4A and the fixing portion 6 with the naked eye. However, when the bottom member 4A and the fixing portion 6 have different colors, more specifically, for example, the bottom member 4A is made transparent and the molten resin forming the fixing portion 6 is colored (colored and opaque). When the material is used, or after making the bottom member 4A transparent, the fixing portion 6 is opaque (the molten resin forming the fixing portion 6 is transparent, and the surface of the fixing portion 6 is a satin pattern (uneven In this case, since the fixing portion 6 and the bottom member 4A are visually recognized as different members, the fixing portion 6 is visually recognized in a belt-like manner, and has a good design finish. Become.

第一実施形態の飲料容器1は、インサート成形によりコップ胴体2の下側開口端部24とリング5とを一体化するので、両者の間(ガラスと樹脂との境界部分)には隙間は出来ず、その結果、汚れが付着しづらいものと言える。
またインサート成形時に金型内において、下側開口端部24の半径方向に関しては、リング5により(外径側を外リング52により、内径側を内リング54により)位置決めするので、型締め時には樹脂製のリング5が金型に接触することになり、ガラス製のコップ胴体2が破損するのを防止することができる。
しかも外リング52の外径を段差面22aの外径よりも大きくし、内リング54の内径を下側開口端部24の下端面24aの内径よりも小さくしてあるので、貫通方向の寸法に関して、図示のように外側位置決め部材86の寸法を、外リング52の寸法よりも長くし、内側位置決め部材84の寸法を内リング54の寸法よりも長くしておけば、コップ胴体2を内側及び外側位置決め部材84,86に触れさせることなく、容易に金型内に挿入できる。
また金型に挿入した後、型締め時にコップ胴体2がリング5と共に貫通方向に少々動いたとしても、金型(外側位置決め部材86及び内側位置決め部材84)が下側開口端部24の付近でコップ胴体2に接触するのを防止することができる。
さらに外リング52と内リング54とをリング接合部56により接合された1つのリング5とし、このリング5と底体4とを1つのインサート部品(底部材4A)としているので、下側開口端部24への位置決めが容易に行え、インサート成形を容易に行える。
Since the beverage container 1 of the first embodiment integrates the lower opening end 24 of the cup body 2 and the ring 5 by insert molding, there is a gap between them (the boundary between glass and resin). As a result, it can be said that dirt is difficult to adhere.
Further, in the mold at the time of insert molding, the radial direction of the lower opening end 24 is positioned by the ring 5 (the outer diameter side by the outer ring 52 and the inner diameter side by the inner ring 54). The made ring 5 comes into contact with the mold, and the glass cup body 2 can be prevented from being damaged.
Moreover, the outer diameter of the outer ring 52 is made larger than the outer diameter of the step surface 22a, and the inner diameter of the inner ring 54 is made smaller than the inner diameter of the lower end surface 24a of the lower opening end 24. If the dimension of the outer positioning member 86 is made longer than the dimension of the outer ring 52 and the dimension of the inner positioning member 84 is made longer than the dimension of the inner ring 54 as shown in the drawing, the cup body 2 is moved to the inner and outer sides. It can be easily inserted into the mold without touching the positioning members 84 and 86.
Further, even after the cup body 2 is moved in the penetrating direction together with the ring 5 after being inserted into the mold, the mold (the outer positioning member 86 and the inner positioning member 84) is located near the lower opening end 24. Contact with the cup body 2 can be prevented.
Further, the outer ring 52 and the inner ring 54 are combined into one ring 5 joined by a ring joint 56, and the ring 5 and the bottom body 4 are used as one insert component (bottom member 4A). Positioning to the part 24 can be easily performed, and insert molding can be easily performed.

本発明の第二実施形態の飲料容器1は図5に示すように、第一実施形態と相違するのは、リング5と底体4とを別部品としたこと、底体4以外(リング5及び固着部6を含む連結部3と、コップ胴体2と)を一体成形した1つのインサート成型品とし、インサート成形品の一部である連結部3のうち固着部6に底体4を溶着したことである。詳しくは以下の通りである。   As shown in FIG. 5, the beverage container 1 of the second embodiment of the present invention is different from the first embodiment in that the ring 5 and the bottom body 4 are separate parts, except for the bottom body 4 (ring 5 And the connecting portion 3 including the fixing portion 6 and the cup body 2) are integrally molded, and the bottom body 4 is welded to the fixing portion 6 of the connecting portion 3 which is a part of the insert molded product. That is. Details are as follows.

リング5は、外リング52と、内リング54とから構成され、第一実施形態のリング接合部56を有さない。外リング52は第一実施形態と同一である。内リング54は、その内径を下側開口端部24の下端面24aの内径よりも小さくし、その外径を下側開口端部24の外径より大きくし、下側開口端部24の下端面24aの全面に接触するようになっている。また内リング54は、環状の本体部(符号省略)のほかに、本体部の外周部から上方に突出する起立片54aを備えている。起立片54aは環状(円環状)であって、内リング54の周方向全周に亘って形成され、下側開口端部24の外周面に嵌め込むようになっている。   The ring 5 includes an outer ring 52 and an inner ring 54, and does not have the ring joint portion 56 of the first embodiment. The outer ring 52 is the same as that of the first embodiment. The inner ring 54 has an inner diameter smaller than an inner diameter of the lower end surface 24 a of the lower opening end 24, an outer diameter larger than an outer diameter of the lower opening end 24, and a lower opening 24. The entire end surface 24a is brought into contact. The inner ring 54 includes an upright piece 54a protruding upward from the outer peripheral portion of the main body portion in addition to the annular main body portion (reference numeral omitted). The upright piece 54 a is annular (annular), is formed over the entire circumference of the inner ring 54, and is fitted into the outer peripheral surface of the lower opening end 24.

固着部6は、被覆部62と内鍔部64とを備える点が第一実施形態と同一であり、内鍔部64の内周端が内リング54の内周端の近傍に位置する点が相違する。また固着部6の内周面と下側開口端部24の外周面には抜け止め用の凹部7aと凸部7bが形成されており、この凹部7aと凸部7bの設け方を第一実施形態と逆にしてある。凹部7aは、固着部6の被覆部62の内周面に備えるものとし、凸部7bを下側開口端部24の外周面に備えるものとしてある。また凹部7aと凸部7bは、周方向全周に亘って間隔をあけて複数個所に設けると共に、ネジとしてある。つまり凹部7aと凸部7bはそれぞれ円周方向に複数配置されており、多条ネジを形成している。   The fixing portion 6 is the same as the first embodiment in that it includes a covering portion 62 and an inner flange portion 64, and the inner peripheral end of the inner flange portion 64 is located in the vicinity of the inner peripheral end of the inner ring 54.

The form is reversed. The concave portion 7 a is provided on the inner peripheral surface of the covering portion 62 of the fixing portion 6, and the convex portion 7 b is provided on the outer peripheral surface of the lower opening end portion 24. The concave portions 7a and the convex portions 7b are provided at a plurality of locations at intervals over the entire circumference in the circumferential direction, and are formed as screws. That is, a plurality of concave portions 7a and convex portions 7b are arranged in the circumferential direction, forming a multi-threaded screw.

底体4は、周壁部42、外鍔部44、外壁部46、底板部48を備える点は、第一実施形態と同一であり、周壁部42の上端が外鍔部44の上面と交差するように連続する点、言い換えれば周壁部42の上端部が外鍔部44よりも上方に突出していない点が第一実施形態と相違する。また底体4と固着部6は互いに溶かして着けられることによって一体化する。この一体化した状態を強固に保つために、上下に重ね合わせて溶着される外鍔部44(底体4)と内鍔部64(固着部6)には互いに嵌り合う突部44aと窪み部64aが形成されている。突部44aは、外鍔部44の外周部から上方に突出するもので、窪み部64aは内鍔部64の外周部において上向きに凹んだものである。   The bottom body 4 is the same as the first embodiment in that it includes a peripheral wall portion 42, an outer flange portion 44, an outer wall portion 46, and a bottom plate portion 48, and the upper end of the peripheral wall portion 42 intersects the upper surface of the outer flange portion 44. Thus, it is different from the first embodiment in that it is continuous, in other words, the upper end portion of the peripheral wall portion 42 does not protrude above the outer flange portion 44. The bottom body 4 and the fixing portion 6 are integrated by being melted and attached to each other. In order to keep this integrated state firmly, a protrusion 44a and a recess that fit each other on the outer flange portion 44 (bottom body 4) and the inner flange portion 64 (fixed portion 6) that are overlapped and welded to each other. 64a is formed. The protruding portion 44 a protrudes upward from the outer peripheral portion of the outer flange portion 44, and the recessed portion 64 a is recessed upward at the outer peripheral portion of the inner flange portion 64.
