Description

本発明は、ペットボトルの注ぎ口に直接口をつけて飲料を飲んでも口腔内の雑菌が飲料の中に入らない雑菌混入防止キャップに関するものである。 The present invention relates to an anti-bacterial contamination prevention cap that prevents germs in the oral cavity from entering the beverage even when a beverage is taken with a mouth directly attached to the spout of a plastic bottle.

通常ペットボトルの注ぎ口は外周に雄ねじが成形されていてこの雄ねじに螺合する雌ねじが内周に成形されたキャップで開閉が可能となっている。このキャップを閉めれば空気中の雑菌がペットボトル内に入ることを防止できる。また、直接口をつけて飲んでも注ぎ口に雑菌が繁殖しないように清掃しやすくした構造のキャップや、雑菌を含む空気がペットボトル内に残って飲みかけの飲料に雑菌が繁殖することを防ぐ目的でペットボトルを蛇腹状に収縮させて空気を排除するペットボトルの構造が知られている（特許文献１〜２参照）。 Usually, a spout of a PET bottle has a male screw formed on the outer periphery, and can be opened and closed with a cap formed on the inner periphery of a female screw that is screwed into the male screw. If this cap is closed, germs in the air can be prevented from entering the PET bottle. Caps with a structure that makes it easy to clean so that germs do not propagate in the spout even if you drink directly with a mouth, and air containing germs remain in the PET bottle to prevent germs from propagating in drinks For the purpose, a structure of a plastic bottle is known in which the plastic bottle is contracted in a bellows shape to exclude air (see Patent Documents 1 and 2).

各種運動には適度な水分補給が必要でありペットボトル飲料は携帯性の良さから広く利用されている。同時に飲料を飲む際にはコップ等を使うことが煩雑であるためペットボトルの注ぎ口に直接口をつけて飲む、いわゆる「ラッパ飲み」が頻繁に行われている。しかしペットボトルの注ぎ口に人が直接口をつけて飲料を飲んだ場合には、口腔内に触れた飲料や唾液がペットボトルの中の飲料と循環するため口腔内に常在する最低でも１億を超えると言われる数の雑菌が少なからずペットボトルの中に混入し時間の経過とともに増殖して、その飲料を再び飲んだ場合には健康を害するおそれがある。特に気温が高くなる夏場はその現象が顕著である。 Various exercises require moderate hydration, and PET bottle drinks are widely used because of their good portability. At the same time, since it is cumbersome to use a cup or the like when drinking a drink, so-called “trumpet drinking” is often performed by placing a mouth directly on the spout of a plastic bottle. However, when a person drinks a beverage by directly putting a mouth into the spout of the plastic bottle, the beverage or saliva that touched the oral cavity circulates with the beverage in the plastic bottle, so at least 1 that is always present in the oral cavity. There are not a few germs that are said to exceed 100 million, and they are mixed in PET bottles and proliferate with the passage of time. This phenomenon is particularly noticeable in summer when the temperature rises.

特許文献１ではペットボトルの注ぎ口に清掃しやすい形状のキャップを設けて、口をつけて飲んだ後にこのキャップを清掃すれば雑菌は排除できるとしているが、キャップ周りの雑菌は取り除けてもペットボトル内の飲料に口腔内の雑菌が入ることは防げない。また特許文献２では飲みかけのペットボトル内に空気が残っているとその空気に混じった雑菌が飲料の中で増殖するおそれがあるため空気の容量分だけ蛇腹状のペットボトルを収縮させて空気を排除する考案であるが、口をつけて飲料を飲んだ場合には飲料自体に口腔内の雑菌が混入するためペットボトル内の空気量を排除しただけでは雑菌の増殖を防ぐことができない。
本発明は、以上の問題点を解決するものである。In Patent Document 1, a cap with a shape that is easy to clean is provided at the spout of a PET bottle, and it is said that if the cap is cleaned after drinking, the germs can be eliminated, but even if the germs around the cap are removed, the pet It is not possible to prevent germs in the oral cavity from entering the beverage in the bottle. In Patent Document 2, if air remains in a drinking plastic bottle, germs mixed in the air may grow in the beverage. However, when a drink is taken with the mouth open, germs in the oral cavity are mixed into the beverage itself, so that it is not possible to prevent the growth of germs simply by eliminating the amount of air in the PET bottle.
The present invention solves the above problems.

筒状の本体下部にペットボトルの注ぎ口の雄ねじと螺合する雌ねじを設け、その雌ねじの天井中央から上方に貫通する噴出口を設け、噴出口の上方に空間を保つ位置まで筒状の本体上端が伸びて形成される接触縁を設けた本体と、この本体に回動可能にヒンジでつながれ本体の接触縁を塞ぐ回動位置では本体の突起と嵌合固着すると同時に噴出口を塞ぐ凸部を有する蓋体。
以上の構成よりなる雑菌混入防止キャップ。A cylindrical main body is provided at the bottom of the cylindrical main body, provided with a female screw that is screwed into the male screw of the spout of the PET bottle, and provided with a jet port penetrating upward from the center of the ceiling of the female screw to maintain a space above the jet port. A main body provided with a contact edge formed by extending the upper end, and a convex part which closes the jet outlet at the same time as fitting and fixing to the protrusion of the main body at a rotation position where the main body is hinged to be able to rotate and close the contact edge of the main body A lid body.
The antimicrobial contamination prevention cap which consists of the above structure.

ペットボトルの注ぎ口に本発明を装着した場合、直接口をつけて飲料を飲んだとしても飲料が噴き出す噴出口と唇が接触する接触縁が離れていて間に空間があるため唇が直接噴出口に触れることはない。飲料はその空間を飛び越えて一方通行で口腔内に達する。よって口腔内の雑菌が飲料の中に混入することがなく飲料の安全性が保たれる。また飲み終わったら噴出口に蓋をすれば空気中の雑菌が飲料の中に入ることも防止できる。 When the present invention is attached to the spout of a plastic bottle, even if you drink a drink with a direct mouth, the lip sprays directly because there is a space between the spout from which the beverage spouts and the lip contacts the contact edge. Never touch the exit. The beverage jumps over the space and reaches the oral cavity in one way. Therefore, the germs in the oral cavity are not mixed in the beverage, and the safety of the beverage is maintained. In addition, if the spout is covered after drinking, it is possible to prevent germs in the air from entering the beverage.
