本考案は、主として牛乳、コーヒー、清涼飲料、果実飲料、茶、酒類、調味料 等の液体を入れる紙容器や、瓶、プラスチックのボトル等の口部に取付けられる 不正開封防止機能付きキャップに関するものである。 The present invention mainly relates to a paper container for storing liquids such as milk, coffee, soft drinks, fruit drinks, tea, alcoholic beverages, seasonings, etc., and a cap with a tamper-proof function which is attached to the mouth of a bottle or plastic bottle. It is.
【０００２】[0002]
従来、この種のキャップは、図７及び図８に示すように、紙容器の口部に取付 けられるキャップ本体３１の液体注出筒３２に上キャップ３３の蓋体３４を開閉 自在に嵌合させるキャップにおいて、前記キャップ本体３１の液体注出筒３２の 下側に、これと同径で外周面にアンダーカット部３５を有する嵌合筒３６を設け 、一方、前記上キャップ３３の蓋体３４の下端に、これと同径で内周面に前記嵌 合筒３６のアンダーカット部３５に強制的に嵌合する突部３７を有する環状帯体 ３８を、開環部３９が縦方向へ繋がっている脆弱部４０を介して連設するように 形成されていた。 Conventionally, as shown in FIGS. 7 and 8, this type of cap has a lid 34 of an upper cap 33 which is openably and closably fitted to a liquid discharging tube 32 of a cap body 31 attached to the mouth of a paper container. In the cap to be provided, a fitting cylinder 36 having the same diameter and having an undercut portion 35 on the outer peripheral surface is provided below the liquid discharging cylinder 32 of the cap body 31, while the lid body 34 of the upper cap 33 is provided. An annular band 38 having a protrusion 37 having the same diameter and an inner peripheral surface forcibly fitted to the undercut portion 35 of the fitting tube 36 is connected to the lower end of the It was formed so as to be connected continuously via the weakened portion 40.
【０００３】[0003]
ところが、使用時に、キャップ本体３１の嵌合筒３６のアンダーカット部３５ に上キャップ３３の環状帯体３８の突部３７を上から回しながら単なる嵌合して いたことから、脆弱部４０の各開環部３９の隙間が多く開いているため、塵や埃 が上キャップ３３の内部に入りやすく、頗る不衛生であった。 However, since the projection 37 of the annular band 38 of the upper cap 33 was simply fitted into the undercut portion 35 of the fitting cylinder 36 of the cap body 31 from above during use, each of the weak portions 40 Since there are many gaps in the ring opening 39, dust and dirt easily enter the inside of the upper cap 33, which is extremely unsanitary.
【０００４】 それに、上キャップ３３の脆弱部４０が縦方向へ繋がっていることによって、 上キャップ３３の成形時に、図９に示すように、上キャップ３３の脆弱部４０の 内部にも左側型４１及び右側型４２を左右側方から入れなければならないため、 上キャップ３３の成形後に、左側型４１及び右側型４２を左右側方へ割らなけれ ばならず、金型が上型４３、下型４４、左側型４１、右側型４２の 4種類必要と なり、金型が複雑で金型及び製品コストのアップの要因になっていた。In addition, since the weak portion 40 of the upper cap 33 is connected in the vertical direction, the left mold 41 is also formed inside the weak portion 40 of the upper cap 33 when the upper cap 33 is formed, as shown in FIG. Since the right mold 42 and the right mold 42 must be inserted from the left and right sides, after the upper cap 33 is formed, the left mold 41 and the right mold 42 must be divided into left and right sides. Therefore, four types of molds, a left mold 41 and a right mold 42, are required, and the mold is complicated, which causes an increase in mold and product costs.
【０００５】 そこで、本考案の課題は、上述のような観点に鑑みて案出されたもので、塵や 埃が内部に入るのを防止して、頗る衛生的に保持できるようにすると共に、金型 を簡素化して、金型及び製品コストの削減を図れるような不正開封防止機能付き キャップを提供することにある。[0005] Therefore, an object of the present invention has been devised in view of the above-mentioned point of view, and prevents dust and dirt from entering the inside so that it can be held extremely hygienically. An object of the present invention is to provide a cap with a tamper-proof function that simplifies the mold and reduces the cost of the mold and the product.
