Description
【０００１】[0001]
本考案は高周波加熱シール用キャップに関し、さらに詳しくは容器開口部の上 に、アルミニウム箔の下面に合成樹脂製フィルムをラミネートさせてなるシール 部材（以下、単に「シール部材」という）を載置し、容器開口部と螺合した状態 で高周波加熱によって密封させる際に使用されるキャップに関する。 The present invention relates to a high-frequency heat-sealing cap, and more specifically, a sealing member (hereinafter simply referred to as "sealing member") formed by laminating a synthetic resin film on the lower surface of an aluminum foil is placed on the container opening. The present invention relates to a cap used for sealing by high-frequency heating while being screwed into a container opening.
【０００２】[0002]
従来より合成樹脂製容器の開口部の上にシール部材を載置し、キャップを螺合 した状態で高周波加熱して容器開口部にシール部材の下面側の合成樹脂製フィル ムを溶着させて容器開口部を密封させる方式が取られている。この場合、キャッ プ内天面がシール部材の上面アルミニウム箔にじかに接触していると、この部分 も溶着して密封後のキャップを開けにくくするため、シール部材の上に紙やセロ ファン等の高融点合成樹脂製フィルムを配置したり、アルミニウム箔をじかに上 面に配して高周波加熱シールを施す場合にはキャップ内天面との接触面積を出来 るだけ小さくする工夫を凝らしたキャップが提案されている。例えば、特公昭５ ８−４４５５５号公報には、容器口部に設けられたフランジ部に対応する内天面 にリング状の小突起を設けるとともに、該小突起の内側および外側に環状溝を設 けたキャップが開示されている。これは内天面に設けたリング状小突起のフラン ジ部に対する押圧力を集中させ、かつ高周波発振時の余剰の発熱を小突起先端部 に伝導し、この溶融部を両環状溝内に変形収納することによりシール性を改善す るものである。しかし、フランジ部と一体構成となる拮れ部を設ける等構造が複 雑である。 Conventionally, a sealing member was placed on the opening of a synthetic resin container, and high-frequency heating was performed while the cap was screwed on, and the synthetic resin film on the lower surface of the sealing member was welded to the opening of the container. A method of sealing the opening is adopted. In this case, if the top surface of the inside of the cap is in direct contact with the upper surface aluminum foil of the seal member, this part will also be welded and it will be difficult to open the cap after sealing. When placing a high-melting point synthetic resin film or placing an aluminum foil directly on the upper surface for high-frequency heat sealing, we propose a cap that makes the contact area with the top surface of the cap as small as possible. Has been done. For example, in Japanese Examined Patent Publication No. 58-44555, a ring-shaped small protrusion is provided on the inner top surface corresponding to the flange portion provided at the container mouth, and annular grooves are provided inside and outside the small protrusion. A digit cap is disclosed. This concentrates the pressing force on the flange of the ring-shaped small projection on the inner top surface, and conducts the excess heat generated during high-frequency oscillation to the tip of the small projection, transforming this fusion zone into both annular grooves. By storing it, the sealing property is improved. However, the structure is complicated, such as providing a constricted part that is integral with the flange part.

本考案は、キャップ内天面にリング状の小突起を設ける従来品に比べて構造が 簡単であり、密封性が確保されると共にキャップ内天面とシール部材の上面アル ミニウム箔との溶着をもたらさず、従って密封後のキャップの開栓の支障を来さ ない新しいタイプの高周波加熱シール用キャップを提供することを目的としてい る。 The present invention has a simpler structure than the conventional product in which a ring-shaped small protrusion is provided on the top surface of the cap, and the sealing performance is secured, and at the same time, the top surface of the cap and the aluminum foil of the sealing member are welded together. Therefore, it is an object of the present invention to provide a new type of cap for high-frequency heat sealing, which does not bring about a problem and therefore does not hinder the opening of the cap after sealing.

本考案は、合成樹脂製容器口部のねじ山上方の開口部に螺合するポリエチレン 系の合成樹脂製キャップにおいて、内天面に容器開口部の外周面に対応する位置 をほぼ中央とする環状溝を設けると共に該環状溝の内側間低面は外側低面に対し て天面側に０．０５〜１ｍｍ程度下まわった段差で凹陥部を形成していることを 特徴とする高周波加熱シール用キャップである。 The present invention relates to a polyethylene synthetic resin cap that is screwed into the opening above the screw thread of the synthetic resin container opening, and has an annular shape with the inner top surface corresponding to the outer peripheral surface of the container opening in the approximate center. For high-frequency heat sealing, characterized in that a groove is provided and the lower surface between the inner side of the annular groove is formed with a step lowering by 0.05 to 1 mm on the top surface side than the outer lower surface. It is a cap.
【０００５】[0005]
以下、本考案のキャップおよびこれを用いた容器開口部の密封方法を図面に示 した実施例に基づき説明する。 Hereinafter, a cap of the present invention and a method for sealing a container opening using the cap will be described with reference to the embodiments shown in the drawings.
【０００６】 図１は容器開口部（１）の上に図３に例示するシール部材、すなわち周辺の一 部に引手つまみ(２)を有するアルミニウム箔(３)の下面に合成樹脂製フィルム( ４)をラミネートさせたシール部材(５)を載置し、これに本発明のキャップ(６) を被せて容器開口部(１)と螺合したときの状態を示す断面図であり、図２は図１ に記したＡ部の拡大図である。容器開口部(１)の上に載置されたシール部材(５) は、キャップ(６)の内天面に設けた環状溝(７)を塞いでスペース（空気層）を形 成すると共に容器開口部(１)の外端部を張り出たシール部材(５)は環状溝(７)の 外側下端部と密着し、いくらか折り込まれている。FIG. 1 shows the sealing member illustrated in FIG. 3 above the container opening (1), that is, a synthetic resin film (4) on the lower surface of an aluminum foil (3) having a pull tab (2) at a part of the periphery. FIG. 2 is a cross-sectional view showing a state in which a seal member (5) laminated with (1) is placed, and the cap (6) of the present invention is put on the seal member (5) and screwed into the container opening (1). It is an enlarged view of the A section described in FIG. The sealing member (5) placed on the container opening (1) closes the annular groove (7) provided on the inner top surface of the cap (6) to form a space (air layer) and the container. The sealing member (5) protruding from the outer end of the opening (1) is in close contact with the outer lower end of the annular groove (7), and is somewhat folded.
【０００７】 そして、この状態で高周波を発振させるとアルミニウム箔(３)が発熱し、これ に積層された合成樹脂製フィルムは容器開口部(１)に溶着して密封性が確保され る。Then, when a high frequency is oscillated in this state, the aluminum foil (3) generates heat, and the synthetic resin film laminated on the aluminum foil (3) is welded to the container opening (1) to ensure hermeticity.
【０００８】 ところで、高周波シールにおいては、先ずアルミニウム箔(３)の最外端を発熱 させ、順次内部方向へ発熱させることから、本考案のキャップにあっては、その 内天面が、容器開口部(１)の上端外周面対応部において環状溝(７)を形成し、且 つ環状溝(７)の外側下端部がアルミニウム箔(３)を押圧しているため、この環状 溝(７)の外側下端部は熱伝導遮断効果を奏し、又、これが発熱により溶融しても 環状溝(７)に存在する空気層が冷却媒体として作用するのと相まって、高周波発 振によってキャップ内天面とアルミニウム箔(３)との間で実質的な溶着は起こら ず、密封後のキャップを開けるのに何ら支障を来さないという予想外の効果を奏 するのであり、特筆すべき事柄である。By the way, in the high-frequency seal, first, the outermost end of the aluminum foil (3) is heated to sequentially generate heat inward. Therefore, in the cap of the present invention, the inner top surface of the cap is the container opening. Since the annular groove (7) is formed at the upper end outer peripheral surface corresponding portion of the portion (1), and the outer lower end of the annular groove (7) presses the aluminum foil (3), the annular groove (7) is formed. The outer lower end of the has a heat conduction blocking effect, and even if it melts due to heat generation, the air layer existing in the annular groove (7) acts as a cooling medium, and high-frequency vibration causes the upper surface of the inside of the cap to This is a matter of special note because it does not cause substantial welding with the aluminum foil (3) and has the unexpected effect of not causing any trouble in opening the cap after sealing.
【０００９】 本考案において、キャップを構成するポリエチレン系の合成樹脂は融点（軟化 点）が１２０℃以上の硬質のものが使用される。In the present invention, the polyethylene-based synthetic resin forming the cap is a hard one having a melting point (softening point) of 120 ° C. or higher.
【００１０】 容器開口部(１)に載置されたシール部材(５)は、高周波加熱処理によって下面 側の合成樹脂製フィルム(４)が容器開口部(１)に溶着して密封性を保持する。他 方、上面側のアルミニウム箔(３)は引手つまみ(２)を引き上げることによって容 易に剥がすことができる。The sealing member (5) placed on the container opening (1) retains hermeticity by the high-frequency heat treatment by welding the synthetic resin film (4) on the lower surface side to the container opening (1). To do. On the other hand, the aluminum foil (3) on the upper surface side can be easily peeled off by pulling up the pull tab knob (2).
【００１１】 なお、合成樹脂製フィルム(４)にはその中央部に内容物(例えばマヨネーズ)を デコレーション的に吐出できるように星形の吐出孔を設けたものや星形状にミシ ン目を入れたものであってもよい。The synthetic resin film (4) is provided with a star-shaped discharge hole in the center thereof so that the contents (eg, mayonnaise) can be discharged in a decorative manner, or a star-shaped perforation is formed. It may be
【００１２】 さらにシール部材としては本考案図面に示した構成以外にも各種アルミニウム 箔を含むラミネート材を用いることができる。アルミニウム箔の上部に各種の断 熱材、非熱伝導材、例えば紙、セロファン紙、セラミック、高融点樹脂フィルム を用いることは何ら差し支えない。Further, as the seal member, a laminate material including various aluminum foils can be used in addition to the configuration shown in the drawings of the present invention. It is safe to use various heat insulating materials and non-heat conductive materials such as paper, cellophane paper, ceramics and high melting point resin films on the aluminum foil.
【００１３】[0013]
以上説明したように、本考案によれば、従来みられたようにキャップ内天面に リング状の小突起を設けずに、キャップ内天面に容器開口部の外周面に対応する 位置に環状溝を設けると共に該環状溝の内側間低面は段差のある凹陥部を形成し ているという簡単な構造で密封性が確保されると共にキャップ内天面とシール部 材との溶着をもたらさず、従って密封後のキャップを開けるのに支障を来さない 新しいタイプの高周波加熱シール用キャップを提供することができる。 As described above, according to the present invention, the ring-shaped small projections are not provided on the top surface of the cap as is conventionally seen, and the top surface of the cap is annularly positioned at a position corresponding to the outer peripheral surface of the container opening. With a simple structure in which a groove is provided and the lower surface between the inner sides of the annular groove forms a stepped concave portion, sealing performance is ensured, and the top surface inside the cap and the sealing member are not welded. Therefore, it is possible to provide a new type of high frequency heat sealing cap that does not hinder the opening of the sealed cap.
