Abstract

A container lid of the type which closes an opening of a container when it is bonded to a flange at the opening and can be torn off for opening the container when the contents are to be taken out. If the container lid is composed of a laminate layer material of plastic films or the like, it is difficult to satisfy two requirements of permitting easy opening and securely bonding the lid to the container by heat sealing. If bonding of the lid to the container is made tightly by heat sealing, the lid cannot be removed easily. In the present invention, an intermediate member is bonded to an outer member of the container lid in such a manner as to be capable of being peeled-off and an inner member is bonded to the outer member in such a manner that the inner member covers the intermediate member and is bonded to the container. With this container lid, when the outer member is pulled up, the inner member is cut along the inner edge profile of the intermediate member and the container is opened. This container lid can be bonded positively to the container and the container can be readily opened by tearing off the lid.

この発明をよ り詳細に記述するために 、 以下、 添酎図面に 従っ て、 これを説明する。  In order to describe this invention in more detail, this will be described below with reference to shochu drawings.
ま ず、 外劐材が母材と補助材との複合材から なる実施例に ついて説明する。  First, an embodiment in which the outer material is a composite material of a base material and an auxiliary material will be described.
第 1 図において 1 は容器蓋である。 容器蓋 1 は、 平面視に おける 4 頂角のう ちの 1 頂角を除き残り の 3 頂角の角を丸め た正方形の上端開放のプラスチッ ク成形容器 1 0 0 のフラン ジ 1 0 1 ( 第 3 図参照) に 、 環状のシール域 2 0 ( 鎖接で示 す ) において接着されてこの容器を密封するものであ っ て 、 第 2 図に示すよ う に外倒材 2 、 中圊材 5 及び内翻材 6 を備え る  In FIG. 1, 1 is a container lid. The container lid 1 is a plastic-molded container 100 with an open top end of a square with the other three apex angles rounded off except for one of the four apex angles in plan view. 3), the container is sealed in an annular sealing area 20 (indicated by a chain connection) to seal the container. As shown in FIG. 5 and inversion material 6
外僵材 2 は母材 3 と補助材 4 とからなる複合材である。 母材 3 は ¾記フランジ 1 0 1 を丁度覆い得る輪郭 7 を有す る。 輪郭 7 は、 シール域 2 0 の外縁輪郭 2 0 a に沿っ てその 外 fit近傍を一周 しているが、 筘記角を丸めていない頂角の近 傍の輪郭部分 7 a は、 外緣輪郭 2 0 a との隔り が他の輪郭部 分 7 b に おけるよ り 大き く 、 その隔り の最大植 d を与える対 角線 1 1 の近傍部分 は 、 母材 と一体を な し 母材 3の一 部分を な すつ ま み部 8をな す 。 つ ま み部 8 は こ れ f つ ま んで対角線 1 1 の方向であ る 開口方向 1 2 に 引 張る た め の 部分である 。 補助材 4 は母材 3の内面の う ち 外縁輪郭 2 0 aか ら離隔 し た つ ま み部 8の部分に 、 ヒ ー 卜 シ ール等の 手段 に よ っ て接着 さ れて い る 。 Outer material 2 is a composite material consisting of base material 3 and auxiliary material 4. The base material 3 has a contour 7 that can just cover the flange 101. The contour 7 goes around the outer fit along the outer edge contour 20 a of the seal area 20, but the contour part 7 a near the apex angle where the angle is not rounded is the outer contour. The pair that gives the maximum plant d of that gap is larger than the other contour part 7 b in the distance from 20 a. The portion in the vicinity of the square line 11 is integrated with the base material and forms a pinch portion 8 that forms a part of the base material 3. The knob portion 8 is a portion for pulling in the opening direction 12 which is the direction of the diagonal line 11 by holding the knob f. The auxiliary material 4 is adhered to the inner surface of the base material 3 by means of a heat seal or the like at a portion of the tab portion 8 separated from the outer edge contour 20a by a means such as a heat seal. .
中 圊材 5 は 、 前記正方形の 4辺の う ち つ ま み部 8を挟む 2 辺 9 , 1 0 に 洽 つ た 帯状をな し 、 その内縁輪郭 5 bは引 裂き 予定線 1 5 ( 第 1 図 ) と一致する 。 一方外縁輪郭 5 aは 、 つ ま み部 8の 部分で は母材 3の輪郭部分 7 a と 外緣輪郭 2 0 a と の園 に あ っ て 、 こ の部分で は中囿材 5 は補助材 4 と一部重 な り 合い 重な り 部分 5 c と な り 、 他の 部分で は外緣! &郭 5 a は母材 3の他の輪郭部分 7 b と ほぼ一致す る 。 中 閭材 5 は 、 重な り 部分 5 cの残余の部分 5 d で 、 母材 3の 内面に剥離可 能に'接着 し て いる 。  The intermediate material 5 has a belt-like shape in which the two sides 9 and 10 sandwich the lip portion 8 of the four sides of the square, and the inner edge contour 5b has a scheduled tearing line 1 5 ( 1 Fig.) On the other hand, the outer edge contour 5 a is located in the garden of the contour part 7 a of the base material 3 and the outer contour 20 a in the knob part 8, and in this part, the Nakazono material 5 is auxiliary. It partially overlaps with the material 4 and becomes the overlapping part 5c, and the other part is outside! & Guo 5a almost coincides with the other contour part 7b of the base material 3. The middle lumber 5 is releasably bonded to the inner surface of the base material 3 at the remaining portion 5d of the overlapping portion 5c.
内側材 6は 、 2辺 9 , 1 0に沿 っ た 帯状をな し 、 その内縁 絵郭 6 bは中 園材 5の内縁輪郭 5 bの 内儺 に あ り 、 そ の外緣 輪郭 6 a は外縁輪郭 5 aの内 «Iに あ っ て 、 かつ 内側材 6は中 園材 5の輪郭の う ち シ ール域 2 0の内縁輪郭 2 0 bよ り 内働 に あ る輪郭部分 5 eを境界 と し て相 接 す る母材 3の内面部 分 3 a と 中 間材 5の 内面部分 5 f と に 跨が っ て 接着さ れて い る 。 従 っ て 、 補助材 4 は 、 中圊材 5 に も 内側材 6に も覆わ れ ない 内 面部分 4 aを有 し 、 こ の部分 は容器 1 0 0の フ ラ ン ジ 1 0 1 へ の シ ールが可能であ り 、 倒 え ば鎖線で示 す線状の シ ( δ ) The inner material 6 has a band shape along two sides 9 and 10, and its inner edge picture section 6 b is located on the inner side of the inner edge contour 5 b of the middle garden material 5, and its outer edge 6 a Is inside the outer edge contour 5 a, and the inner material 6 is the inner edge contour 20 in the seal area 20 of the contour of the middle material 5, which is more inward than the inner edge contour 20 b. The inner surface portion 3a of the base material 3 and the inner surface portion 5f of the intermediate member 5 that are in contact with each other with e as a boundary are stuck and bonded. Accordingly, the auxiliary member 4 has an inner surface portion 4a that is not covered by the intermediate member 5 or the inner member 6, and this portion is connected to the flange 101 of the container 100. It is possible to seal, and if you defeat it, (δ)
ール域 1 4 でシールして誤開口防止用シールとなし得る。 但 しシール域 1 4 でのシールは必ず しも これを しな く てもよ く 実際補助材 4 の材料溝成に よ って はシールできないこ ともあ る 。 ま た 、 補助材 4 の内面の う ち 中 圊材 5 に覆わ れた部分 4 b は中圊材 5 の外面と単に面が重な り合っ ているのみで何 等接着されす、 両者の園 に は微視的 に は際園 1 3 ( 第 4 図 ( a ) 参照 ) がある とい う こ とが特に重要である。 A seal can be made in the rule area 14 to form a seal for preventing erroneous opening. However, the sealing in the sealing area 14 is not always required, and in some cases, the sealing cannot be performed depending on the material groove of the auxiliary material 4. In addition, the part 4b of the inner surface of the auxiliary material 4 that is covered with the intermediate material 5 is bonded to the outer surface of the intermediate material 5 simply because the surface of the auxiliary material 4 overlaps with the outer surface. It is especially important that there is a microscopic view of the basin 13 (see Figure 4 (a)).
このよう に構成された容器蓋 1 は構造が籤単で安優である 第 3 図は容器蓋 1 で容器 1 0 0 を ヒ — 卜 シ ールによ り接着 した状簾を示し 、 このシールは、 倒えば容器 1 0 0 のフラン ジ 1 0 1 のシール域 2 0及びシ ール域 1 4 に対応する部分に 形成されたシール用突起に ヒー 卜 シールによ り接着するこ と ができる。 これによ り容器は完全に密封され、 シール域 1 4 のシールは誤闋ロを防止する 。  The container lid 1 constructed in this way is simple in structure and easy to use. FIG. 3 shows a mound with the container lid 1 bonded to the container 100 with a heat seal. When it is folded down, it can be bonded with a heat seal to a sealing projection formed on a portion corresponding to the seal area 20 and the seal area 14 of the flange 101 of the container 100. . As a result, the container is completely sealed, and the seal in the seal area 14 prevents mistakes.
この容器を開口 する ときは、 まずつ まみ部 8 の先端をつ ま んで開口方向 1 2 に引張り 、 シール域 1 4 の線状シール部を 剥錐する。  When opening this container, first, the tip of the knob 8 is grasped and pulled in the opening direction 12 to peel off the linear seal portion of the seal area 14.
この操作には相応の力を入れるこ とになるが、 線状のシー ルであるからその力 は僅かで充分であ り 、 かつ内儺には剥饞 可能なシール部分 1 6 を介 し て未剥離のシール域 2 0 のシー ルが接続するから 、 はずみで内容物がこぼれる恐れは全く な い。  Although this operation requires a certain amount of force, the force is small and sufficient due to the linear seal, and the inner seal is provided via a peelable seal portion 16. Since the unpeeled seals in the seal area 20 are connected, there is no danger that the contents will spill out due to bounce.
シール域 1 4 を剥離する と補助材 4 と中圊材 5 と/)重な り 部分 5 c に達するがこ こ には鏢間 3 があ り 、 補助材 4 と中 圃材 5 と は何等の 操作も 要さ ず に は じ め か ら 離 さ れ て お り 、 対角糠 1 1 上の剥離距離が一挙 に増大す る 。 When the seal area 14 is peeled off, the auxiliary material 4 and the intermediate material 5 reach the overlapping portion 5c, but there is a gap 3 here, and the auxiliary material 4 and the intermediate material 5 are separated. The field material 5 is separated from the field material without any operation, and the peeling distance on the diagonal bran 11 increases at once.
更に つ ま み部 8 を 引張る と 、 母材 3 は中 圊材 5か ら剥離 し ( 第 4図 ( b ) ) 、 更に 引張る と 内側材 6.は 中 圊材 5の 内縁 輪郭 5 bに 沿 っ て 引 裂かれて 、 容器の初期 開口 が極め て 容易 に行わ れる ( 第 4図 ( c ) ) 。 更に 引張る と 内縁輪郭 5 bに 沿 っ て 円 滑に 開口 が拡大 し 引 裂き予定線 1 5 に 沿 う 開口 が完 了する 。  When the knob 8 is further pulled, the base material 3 separates from the intermediate material 5 (FIG. 4 (b)), and when further pulled, the inner material 6 follows the inner edge contour 5b of the intermediate material 5. Thus, the container is torn and the initial opening of the container is extremely easy (Fig. 4 (c)). By further pulling, the opening smoothly expands along the inner edge contour 5b, and the opening along the planned tearing line 15 is completed.
次に 、 第 2の実施例 と し て外儺材 2が複合材でな く 単体 と し て構成 さ れて い る場合に つ い て 説明 す る 。  Next, as a second embodiment, a case where the outer material 2 is configured as a single body instead of a composite material will be described.

When this peeling reaches the inner edge contour 61 of the inner material 5, the inner material part inside is strongly adhered to the outer material, so that it is pulled following the outer material, and the inner material becomes the inner edge contour. The container 100 is easily opened by tearing along 6 1.
容器蓋 1 はフルオープンであるが、 第 9図に示す外側材 2 と中園材部材 5 5 aと内儺材部材 6 0 a とから なる容器蓋の 場合は、 中圊材部材 5 5 aと内儺材部材 6 0 aが半周分 しか ないので、 第 1 0図に示す如 く セ ミ オープンの容器蓋 1 b と なる。  The container lid 1 is fully open, but in the case of a container lid composed of the outer member 2, the middle garden member 55a and the inner material 60a shown in FIG. 9, the middle member 55a is used. Since the inner member 60a has only a half circumference, it becomes a semi-open container lid 1b as shown in FIG.
容器蓋 1 (第 7図 ) , 1 ( 第 9図 ) 及び 1 G ( 第 1 2図 ) において は、 中閭材部材 5 5 a , 5 5 b及び 5 5 c は半環状 の帯状体であるから 、 その材料ど り は第 1 1 図及び第 1 3図 に示 す如 く 凸部 を周一方向 7 4 に 搛え 、 相 互の凹部 に 凸部が 入 り 込む よ う に し て 行 う こ と がで き 、 瑷状体 6 6 を直接打抜 く 場合 に 比 し て 材料原反 7 3 の使用 量は著 し く 減少する 。 し かも、 更 に内湖材部材 6 0 a, 6 O b 及び 6 O c も同様な帯 状体で ある か ら 、 そ の材料ど り は中囿材 と周様 に行 う こ と が でき 、 内儺材が全円である場合 に 比 し て 、 更 に 大き く 使用材 料の絶対量、 材料原反量共に 節減可能 と な る 。 In the container lids 1 (FIG. 7), 1 (FIG. 9) and 1G (FIG. 12), the middle pulp members 55a, 55b and 55c are semi-annular strips. From Fig. 11 and Fig. 13 As shown in Fig. 7, the protrusions are arranged in the circumferential direction 74 so that the protrusions enter the mutual recesses, and the rods 66 are directly punched. As compared with the case where the raw material 73 is used, the amount used is significantly reduced. Furthermore, since the inner lake lumber members 60a, 6Ob, and 6Oc are similar strips, the materials can be used in the same manner as Nakazono lumber. However, compared to the case where the inner material is a full circle, the absolute amount of used material and the amount of raw material can be reduced even more.
こ の こ と は容器蓋を全周の 1 3 程度開 口 さ せ る よ う に構 成す る場合に おい て も 言え る 。  This can be said even when the container lid is configured to be opened about 13 times around the entire circumference.
ま た 中園材部材 5 5 a は フ ル オ ー プ ン の容器蓋 1 、 セ ミ オ 一プ ン の容器蓋 1 b に 共通に使用 で き る か ら 、 個々 の容器躉 に よ っ て異なる形状の材料を用 いる場合 に 比 し て 、 大き く 轾 費節減を はかる こ と がで きる 。  Also, the middle garden material member 55a can be used in common for the full-open container lid 1 and the semi-open container lid 1b, so it differs depending on the individual container 躉. The cost can be greatly reduced as compared with the case where a material having a shape is used.
第 1 2 図及び第 1 4 図 に示す角型の容器蓋の場合ち周様 に 材料 · 経費節減が可能である 。  In the case of the rectangular container lid shown in FIGS. 12 and 14, the material and cost can be reduced in a circumferential manner.
