傷等の検査、管理が必要となつている。 This glass bottle has a composition that is easy to melt, can be made into any shape, uses cheap raw materials, and is made using a press-blow method. However, if the formed glass bottle is rapidly cooled (left to cool) as it is, residual strain will occur, resulting in a brittle product.In order to remove this strain, it may be slowly cooled from 650℃ to room temperature for about an hour, or hot-processed. Therefore, the molding defect rate is high, and inspection and management of defects, etc. is required.
またガラス容器における炭酸飲料などの市場破

めている。 For this reason, currently containers for carbonated drinks, etc. are also resource-saving.
Containers made of synthetic resin have been replaced in order to save energy and reduce costs. This synthetic resin container is made of PVC (polyvinyl chloride), PET (polyethylene terephthalate) resin, etc.
PVC has become a problem in terms of pollution and hygiene, and PET resin containers are now being widely used as bottles for carbonated drinks.

なつているため、ラムネ瓶用として一体に合成樹
脂化することは困難であつた。 However, ramune bottles are made by placing glass beads inside and tightening the mouth from both sides, and the carbon dioxide gas pushes up the glass beads to seal the bottle, so it is made into a synthetic resin for use in ramune bottles. That was difficult.
またラムネ瓶は内蔵するガラス玉とゴム輪で気

浄が不可能という飲料容器としての致命的な欠点
があり、サイダーに比べて保存期間が短かい。 Although ramune bottles are an excellent idea in that they are kept airtight with built-in glass beads and rubber rings, they have a fatal drawback as a beverage container: they cannot be cleaned aseptically, and they have a shorter shelf life than cider bottles. shellfish.
しかし、このラムネ瓶は構造が変わつていて特

With this configuration, the pressure from carbon dioxide gas pushes up the ball (glass bead) through the through hole in the intermediate plate member, which is much smaller than the inner diameter of the container body, and presses it against the packing member, such as rubber, provided inside the drinking spout. When the container is sealed by pressing the bottle down, and the bottle is opened by pressing down on the ball, bubbles spill out from the spout due to the foaming action of carbon dioxide gas, creating a structure unique to ramune bottles. Furthermore, by making the lower container main body, upper container main body, intermediate plate, etc. of synthetic resin, the ramune container can be made lightweight, safe, and sanitary.

る。Embodiment In FIGS. 1 and 2, a ramune container 1 is a cylinder with a bottom, and has a lower container body 3 made of synthetic resin and having an opening 2 with a smaller diameter at one end, and has a structure unique to ramune bottles. A ring-shaped packing member 5 made of rubber or the like that receives the glass beads (balls) 4 pushed up by the pressure of carbon dioxide inside the container can be pressed against the inner wall of the spout 6, and when the container is opened, It has a convex cylindrical upper container body 8 provided with a protrusion 7 for receiving a glass ball 4.

れ出るラムネ瓶特有の構造を作ることができる。 The lower container body 3 is made of PET resin or the like with gas barrier properties and is made by stretch blow molding, and the upper container body 8 is made of synthetic resin such as PP (polypropylene) ABS or styrene and made by injection molding or the like. Blow molding polyester (PET) resin produces containers with uneven thickness that are opaque due to its high crystallinity and high melting point. For this reason, if the extruded balisong (tube-shaped preform) is stretched to about twice its original size using a stretch-oriented blow method, etc.
It becomes oriented and strong, and the wall thickness becomes thinner, allowing for rapid cooling, which allows transparent containers to be molded. When the resin is biaxially stretched using this method,
Resins have improved physical properties such as improved transparency, reduced creep, increased impact strength, and reduced permeability to gas and water vapor, making it possible to form thin walls, making them more transparent, and lowering costs. The thus-made synthetic resin ramune container 1 of the present invention is used as a container by fixing the lower container body 3 and the upper container body 8 using the threaded portions 13 and 13', and is also used as a container through the through hole 9 of the intermediate plate member 12. Therefore, the pressure of the carbon dioxide gas inside the container body 3 pushes the glass bead 4 up and presses it against the packing member 5 provided inside the spout 6 to seal it, and conversely, when the glass bead 4 is pushed down, the carbon dioxide gas It is possible to create a structure unique to ramune bottles in which foam spills out from the spout 6 due to the foaming action of the bottle.
(効果)
本考案は上記の構成からなるものであるから、
ガラス瓶のように急冷してもこわれることがなく
安全であり、しかも軽量化が可能となり省資源、
省エネルギー及びコストダウンの面において有利
となる。さらにラムネ瓶は形状が複雑で耐内圧力
強度が通常のガラス瓶に比べて低下しており、コ
ーラ、サイダー等は常温で2〜4Kg/cm2の内圧が
あるため、ガラス瓶の強度検査が必要となるが、
樹脂化することによりこれらの手数が省かれる。(Effects) Since the present invention consists of the above configuration,
It is safe because it does not break even when cooled quickly like glass bottles, and it is also lightweight, saving resources.
This is advantageous in terms of energy saving and cost reduction. Furthermore, ramune bottles have a complicated shape and have lower internal pressure resistance than regular glass bottles, and cola, cider, etc. have an internal pressure of 2 to 4 kg/ cm2 at room temperature, so it is necessary to test the strength of glass bottles. However,
By using resin, these steps can be eliminated.
また現在では二軸延伸による樹脂の特性が向上
し、内容物の透過性、遮光性、透明性、衛生性、
耐薬品性、ストレスクラツキング、装飾性、廃棄
物処理性、座屈強度、衝撃強度、耐圧性が良くな
つており、ガラス瓶に比べて著しい特長を有して
いる。 In addition, the properties of resins have been improved by biaxial stretching, which improves the permeability of contents, light-shielding properties, transparency, hygienic properties, and
It has improved chemical resistance, stress cracking, decorative properties, waste disposal properties, buckling strength, impact strength, and pressure resistance, making it a remarkable feature compared to glass bottles.
またPET樹脂は分子構成に窒素を含まず完全
に炭素、水素、酸素の3元素のみから成立つてい
るので安全性が高い。 In addition, PET resin does not contain nitrogen in its molecular structure and is completely composed of the three elements carbon, hydrogen, and oxygen, so it is highly safe.

る。 Ramune bottles had some drawbacks in terms of hygiene due to their structure, but since the container was divided into two and sealed, sterilization was easy and sanitary. Furthermore, since ramune is sold as a soft drink for children, rather than a colorless and transparent container, the lower and upper container bodies can be colored in different colors, or the outside of the container can be printed to create character products such as manga. You can also draw.
