Description
本発明は、乾燥が必要な例えば乾燥食品などの内容物、又は調湿が必要な例えば錠剤などの内容物を収納する容器に装着する乾燥又は調湿機能を有する蓋材に関するものである。 The present invention relates to a lid material having a drying or humidity control function that is attached to a container that stores contents such as dried foods that need drying or contents such as tablets that require humidity conditioning.
従来、容器に収納する内容物に対して乾燥機能を有する蓋材としては、シート状の乾燥剤含有樹脂成形体を蓋材の天板内面下に、パッキンの代わりに挿着したものがあった。 Conventionally, as a lid material having a drying function with respect to contents stored in a container, there has been a sheet-like desiccant-containing resin molded body inserted under the top plate inner surface of the lid material instead of packing. .
しかしながら、上述の従来の乾燥機能を有する蓋材は、容器に収納する内容物が、天板内面下に挿着されている乾燥剤含有樹脂成形体に直接に接触してしまうため、乾燥剤含有樹脂成形体の乾燥剤が内容物へ移行することがあり、食品衛生上の問題、内容物の変質の可能性などの問題があり、また、内容物の乾燥剤含有樹脂成形体への付着の問題や、挿着されている乾燥剤含有樹脂成形体の外周縁部が、蓋材の内周面と容器の周壁外周面間にあるため、外気の水分を吸収することがあり、この水分が乾燥剤含有樹脂成形体を内側へ伝わって容器内へ侵入する問題などがあった。 However, the lid material having the conventional drying function described above contains the desiccant content because the contents stored in the container directly come into contact with the desiccant-containing resin molded body inserted under the inner surface of the top plate. The desiccant of the resin molded product may shift to the contents, which may cause problems such as food hygiene problems and the possibility of alteration of the contents. Since the outer peripheral edge of the problem or the inserted desiccant-containing resin molding is between the inner peripheral surface of the lid and the outer peripheral surface of the peripheral wall of the container, it may absorb moisture from the outside air. There was a problem that the desiccant-containing resin molded body was transmitted inward to enter the container.
本発明は、上述の従来の乾燥機能を有する蓋材の問題点を解決したものであり、食品衛生上の問題や内容物に対する悪影響がなく、乾燥又は調湿の効果が持続性で良好な乾燥又は調湿機能を有する蓋材を提供するものである。 The present invention solves the problems of the above-described conventional lid materials having a drying function, has no adverse effects on food hygiene and contents, and has a drying or humidity conditioning effect that is durable and good drying. Or the cover material which has a humidity control function is provided.

An inner sealing ring for sealing the portion is provided, and a separator having a plurality of ventilation through holes smaller than the projected area of the contents is provided on the inner inner upper side of the inner sealing ring. A desiccant or moisture-conditioner-containing resin molded body is accommodated between the top plate and the upper surface and the outer peripheral surface of the top plate by heat-sealing with the top plate, and the lower surface is thermally bonded to the upper surface of the separator plate, and the peripheral wall A lid member having a drying or humidity control function, characterized in that an engagement portion with a container is provided on an inner peripheral surface.
そして、本発明の第２の発明は、乾燥又は調湿を必要とする内容物を収納する容器に装着する蓋材であって、本体部と蓋部とからなり、本体部の周壁の外周面の一端にヒンジを介して、上方に蓋部を開閉可能に接続し、蓋部の天板の下面に、本体部を封止するインナー封止リングを垂設し、このインナー封止リングの内周面内側上方に、内容物の投影面積より小さい複数個の通気貫通孔をもつ隔離板を設け、この隔離板と天板との間に、乾燥剤又は調湿剤含有樹脂成形体を、上面と外周面を天板と熱融着し、下面を隔離板上面と熱融着して収容し、かつ、本体部の周壁のヒンジ対向側の外周面下端に開閉用つまみを設け、内周面に容器との係合部を設けたことを特徴とする乾燥又は調湿機能を有する蓋材である。 The second invention of the present invention is a lid member to be attached to a container for storing contents that require drying or humidity control, and comprises a main body part and a lid part, and the outer peripheral surface of the peripheral wall of the main body part. A lid is connected to one end of the lid so as to be openable and closable, and an inner sealing ring for sealing the main body is provided on the lower surface of the top plate of the lid. A separator having a plurality of ventilation through holes smaller than the projected area of the contents is provided on the inner side of the peripheral surface, and a desiccant or a humidity control resin molded product is placed between the separator and the top plate. The outer peripheral surface is heat-sealed with the top plate, the lower surface is heat-sealed with the upper surface of the separator plate, and an opening / closing knob is provided at the lower end of the outer peripheral surface on the hinge-facing side of the peripheral wall of the main body.

There are an insert injection molding method and a two-color injection molding method in the above-described method for producing a lid having a drying or humidity control function. The insert injection molding method uses an injection mold having a gate position at the center of a female top plate forming cavity. First, the injection mold on the injection molding machine is opened and a desiccant is used. Alternatively, the moisture-conditioner-containing resin molded body is temporarily fixed to the male top plate forming cavity surface by sucking air from air holes provided at predetermined positions, and then clamped and melted from the gate. Resin is injected into the cavity (the space between the male mold and the female mold in which the molded product is molded) to mold the lid, and at the same time, as shown in FIGS. A separator having the upper surface and outer peripheral surface of the wetting agent-containing resin molded body (200) heat-sealed to the top plate (110), and the lower surface of the desiccant or humidity adjusting agent-containing resin molded body having the ventilation through holes (131) (130) is heat-sealed with the upper surface, and a desiccant or humidity control resin molded product is enclosed and dried. Or it is intended to produce the cover member (100) having a humidity function. In addition, insertion of a desiccant or a humidity control agent-containing resin molded body into a mold is by an inserter.
また、２色射出成形法は、２組の射出装置を備える２色射出成形機を用い、まず、乾燥剤又は調湿剤含有樹脂成形体用射出成形金型で乾燥剤又は調湿剤含有樹脂成形体を作製し、次に、この乾燥剤又は調湿剤含有樹脂成形体を、蓋材用射出成形金型内に移動して、蓋材を成形すると同時に、乾燥剤又は調湿剤含有樹脂成形体の上面と外周面を天板に熱融着し、また、乾燥剤又は調湿剤含有樹脂成形体の下面を通気貫通孔もつ隔離板の上面と熱融着して、乾燥剤又は調湿剤含有樹脂成形体を封入して乾燥又は調湿機能を有する蓋材を作製するものである。 In addition, the two-color injection molding method uses a two-color injection molding machine equipped with two sets of injection devices. First, a desiccant or a humidity-controlling resin is used in an injection mold for a resin molding with a desiccant or humidity-controlling agent. A molded body is prepared, and then the desiccant or humidity control agent-containing resin molded body is moved into the injection molding mold for the lid material to mold the lid material. The top surface and outer peripheral surface of the molded body are heat-sealed to the top plate, and the bottom surface of the desiccant or moisture-conditioner-containing resin molded body is heat-sealed to the top surface of the separator plate having a ventilation through hole to obtain the desiccant or the conditioning material.
