産業上の利用分野
この考案は酒類、又はジユース類等を収容する
瓶に用いる瓶蓋に関するものである。[Detailed description of the invention] Industrial field of application This invention relates to a bottle cap used for a bottle containing alcoholic beverages, juices, etc.
更に詳しくは酒類又はジユース類等のように、
液体を加熱して充填する瓶に用いる瓶蓋に関する
ものである。 More specifically, alcoholic beverages or youth products, etc.
This relates to a bottle lid used for bottles that are heated and filled with liquid.
従来の技術
この考案の考案者は、さきに同種の加熱液体を
充填する瓶に用いる瓶蓋を考案し、実用新案登録
出願を行つた（実開昭58−185560号公報）。Prior Art The inventor of this invention had previously devised a bottle cap for use in bottles filled with the same type of heated liquid, and filed an application for registration of a utility model (Utility Model Publication No. 185560/1983).
この考案は上記出願済み考案の改良に関するも
のであるため、まず上記出願済み考案の瓶蓋につ
いて説明する。 Since this invention relates to an improvement of the above-mentioned invention, the bottle cap of the above-mentioned invention will be explained first.
その瓶蓋は、図示は省略するが、合成樹脂製
で、瓶口の外周に圧接嵌合する筒部を有する蓋体
と、該筒部の外側に圧接嵌合した筒体とから成る
もので、該筒体は前記蓋体を形成する合成樹脂よ
りも融点の高い合成樹脂により形成されている。
これら蓋体及び筒体を形成する合成樹脂の一例を
示せば前記蓋体はポリエチレン樹脂により形成さ
れ、前記筒体はポリプロピレン樹脂により形成さ
れている。 Although not shown, the bottle cap is made of synthetic resin and consists of a lid body having a cylindrical portion that presses into the outer periphery of the bottle mouth, and a cylindrical body that presses and fits on the outside of the cylindrical portion. The cylindrical body is made of a synthetic resin having a higher melting point than the synthetic resin forming the lid.
As an example of the synthetic resins forming the lid and the cylinder, the lid is made of polyethylene resin, and the cylinder is made of polypropylene resin.
そして、瓶に加熱した酒類又はジユース類等を
充填し、上記蓋体により瓶口を閉止する。このよ
うな場合、上記出願済みの瓶蓋を用いずに、一般
に用いられている普通の瓶蓋を用いると、これら

内方に向かうプレストレスが与えられていること
になるから、前記密閉力の減少は、上記プレスト
レスにより補充されて、密閉力の減少を微少にと
どめることができるという効果を有する。 Then, the bottle is filled with heated alcoholic beverages, youth, etc., and the bottle mouth is closed with the lid. In such a case, if a commonly used ordinary bottle cap is used instead of the bottle cap applied for above, the heat of these liquids will be brought to the bottle cap through the bottle mouth,
This heat reduces the elasticity of the pressure-contacting part of the bottle cap, causing so-called conformation to the bottle mouth and reducing the sealing force. Since the cylindrical portion of the lid body is already subjected to inward prestress by the cylindrical body made of a synthetic resin with a higher melting point than the lid body, the reduction in the sealing force is , is replenished by the prestress, and has the effect of minimizing the decrease in sealing force.
考案が解決しようとする課題
前記の出願済み瓶蓋は、前記のように一応その
目的を達しているものであるが、その瓶蓋の使用
の際の密閉の程度を調べてみると、加熱液体を収
容しない場合の瓶蓋の密閉状態に比較すればやは
り若干低下することが否めない。Problems to be Solved by the Invention The above-mentioned bottle cap has achieved its purpose as mentioned above, but when we investigated the degree of sealing when using the bottle cap, we found that the heated liquid It is undeniable that this will be slightly lower than the sealed condition of the bottle lid without containing it.
この考案はこのような欠点を改良し、上記の出
願済みの瓶蓋における使用の際の密閉度の減少
を、該出願済み瓶蓋より一層少くすることのでき
る瓶蓋を提供することである。 The object of this invention is to improve upon these drawbacks and to provide a bottle cap that can reduce the degree of sealing when used in the bottle cap disclosed in the above-mentioned patent application.
課題を解決するための手段
上記の目的を達成するこの考案について述べる

レストレスを与えて常時不動にしまりばめさせら
れている前記筒体４から成る瓶蓋である。Means for Solving the Problems To describe this invention that achieves the above object, it consists of a cylinder part 1 made of synthetic resin that press-fits onto the outer periphery of the bottle mouth, and a cylinder part 1 that is integrally provided inside the cylinder part 1 in the radial direction. In addition, a lid body 3 consisting of a blocking wall 2 that blocks the flow of liquid, and a synthetic resin having a melting point higher than that of the synthetic resin forming the lid body 3, which is press-fitted to the outside of the cylindrical portion 1 of the lid body 3. A cylinder body 4 made of synthetic resin, and a protrusion 5 formed on either the inner peripheral surface of the cylinder body 4 or the outer peripheral surface of the cylinder part 1, allow the cylinder part 1 to have a cylindrical shape. This bottle lid is made up of the cylinder body 4 which is tightly fitted in an immovable manner at all times by applying a prestress inward in the radial direction.
作 用
酒類又はジユース類等を加熱して瓶に充填し、
その瓶の瓶口に上記瓶蓋を嵌着すると、上記加熱
流体の、瓶口を介してもたらされる熱により、蓋
体３の、筒部１の内側の弾性が減少し、いわゆる
瓶口に対するなじみを起し、密閉度が減少しそう
になる。Function: Heat alcoholic beverages or youth drinks, etc. and fill them into bottles.
When the bottle cap is fitted onto the bottle mouth of the bottle, the elasticity of the inner side of the cylindrical portion 1 of the lid body 3 decreases due to the heat of the heated fluid brought through the bottle mouth, so that the elasticity of the lid body 3 on the inside of the cylindrical portion 1 is reduced. This may cause the airtightness to decrease.
この場合該筒部１の外側には、前記蓋体３より
融点の高い合成樹脂により形成された筒体４が、
該筒体４の内周面、又は前記筒部１の外周面のい
づれか一方に形成された突条５により、筒部１の
半径方向内方に向う部分的に強いプレストレスを
与えて、常時不動にしまりばめさせられており、
このことは、前記筒部１に加熱液体の及ぼす熱に
よつては影響されにくい筒体４が、断面積の小さ

弾性の減少に伴う密閉度の低下は、前記突条５の
もたらすプレストレスにより、部分的に強く充分
に補充され、前記の、突条を有しない出願済み瓶
蓋よりも密閉度の低下を一層少なくすることがで
きるのである。 In this case, on the outside of the cylindrical portion 1, there is a cylindrical body 4 made of a synthetic resin having a higher melting point than the lid 3.
The protrusions 5 formed on either the inner circumferential surface of the cylindrical body 4 or the outer circumferential surface of the cylindrical portion 1 apply a strong prestress partially inward in the radial direction of the cylindrical portion 1, so that the cylindrical portion 1 is constantly It is immovably tightly fitted,
This means that the cylindrical body 4, which is not easily affected by the heat exerted by the heated liquid on the cylindrical part 1, has an increased force per unit area due to the ridges having a small cross-sectional area. The ridges 5, which can apply a large amount of pressure, apply a partially strengthened prestress radially inward to the cylindrical portion 1. The decrease in the degree of sealing due to the decrease in elasticity that occurs due to the decrease in elasticity is partially compensated strongly and sufficiently by the prestress caused by the protrusions 5, and the degree of sealing is better than that of the applied bottle cap without the protrusions. This makes it possible to further reduce the decrease.
