Abstract

PURPOSE:To perform a successive and accurate sealing of tubular containers set in rotary motion by subjecting to a high-frequency induction heating said container held by a pressing device using the high-frequency current induced by a tertiary coil thereof. CONSTITUTION:When a pair of pressing instruments 9 set in rotary motion reaches under a primary coil 3, a high-frequency current is induced in a secondary coil 6 by the high-frequency electromagnetic induction of the primary coil 3 with the accompanying yield of the high-frequency current in a tertiary coil 7 contained in the pressing instruments 9. By the use of such current in the coil 7, the metal foil composing a tubular container T held by the pressing instruments 9 is subjected to a high-frequency induction heating, whereby the resins deposited on this metal foil are melted in order for the ends of the container T to be pressingly sealed therewith between the opposing pressing forces of the pressing instruments 9.

A prefabricated cap with a skirt part protruding from below the outer periphery is made, and the cap is crimped onto the mouth part using a heat-resistant elastic material, and in this crimped state, the part near the top of the container mouth corresponds to the shape of the mouth part. A secondary coil with a planar shape that
A fixed primary coil connected to a high-frequency power source is moved close to the secondary coil, and during this close movement, a high-frequency current is generated in the secondary coil, and this current causes only the metal foil in the portion of the cap corresponding to the container opening to be removed. A sealing method is described in which the adhesive is melted by high-frequency induction heating and the camp is bonded only to the upper part of the mouth.

A pair of heating coils arranged in a V-shape are arranged so that the coil surface of each coil faces the sealing part of the tube, and a high magnetic permeability member is interposed between each coil. means for arranging a high magnetic permeability member on the coil side disposed at the distal end of the tube; and a tube contacting portion of a pressurizing device for applying pressure to the sealing portion of the tube to the heating coil. A high-frequency sealing device for a tubular container is described, which includes means for providing a non-magnetic metal material on the top and bottom of the container.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

しかしながら、上記の従来の技術は以下のような問題点
を有していた。However, the above-mentioned conventional technology had the following problems.

即ち、特公昭５Ｂ−２３８５７号公報には、チューブ状
容器を封緘することについての記載はなく、何らの示唆

きず、従ってチューブ状容器を封緘することができない
。In other words, Japanese Patent Publication No. 5B-23857 does not mention or suggest anything about sealing a tube-shaped container, and the sealing method described in the same publication does not include connection to a high-frequency power source (high-frequency oscillator). However, since it does not have a tertiary coil located in a direction substantially orthogonal to the secondary coil, It is not possible to perform high-frequency induction heating on a tubular container containing a vertically positioned metal foil, and therefore it is not possible to seal the tubular container.

また、特公昭５７−８６４５号公報に記載のチューブ状
容器の高周波シール装置は、加熱用のコイルに高周波エ
ネルギーを直接接続して供給するようになしであるため
、チューブ状容器を移動させながら連続的に封緘するこ
とはできない。In addition, the high-frequency sealing device for tubular containers described in Japanese Patent Publication No. 57-8645 does not directly connect and supply high-frequency energy to the heating coil, so it continuously seals while moving the tubular container. It cannot be sealed.

従って、本発明の目的は、チューブ状容器を移動させな

In a method of heating and sealing by high-frequency induction heating, a high-frequency oscillator supplies a high-frequency current to the primary coil, moves the secondary coil with respect to the primary coil, and then seals the secondary coil.
While the secondary coil approaches the primary coil, the
