Description

【0001】
【発明の属する技術分野】
本発明は、粉体食品を収容する缶容器を開口自在に閉塞する缶蓋に関する。
【0002】
【従来の技術】
従来、粉乳等の粉体食品を収容する缶容器に設けられる缶蓋として、粉体食品を取り出す際に計量スプーンのすりきりを行なうすりきり縁がパネル部の一部に形成されているものが知られている。即ち、この種の缶蓋は、缶容器に巻締めるカール部に囲繞されたパネル部と、該パネル部を大略半月状に開口形成された開口部とを備えている。前記パネル部には、該開口部の残部によりすりきり板部が形成されており、該すりきり板部の開口部に臨む直線状の端縁が前記すりきり縁とされている。また、この種の缶蓋は、未開封の状態では、シート状のシール部材によって前記開口部が閉塞されている。該シール部材は、パネル部の外周縁に沿って環状の接着部を介して剥離自在に接着されており、該シール部材によって前記開口部だけでなく前記すりきり板部の上面側も覆われた状態とされている。これにより、未開封の状態では、前記すりきり板部が露出されていないので、該すりきり板部の汚染が防止され、衛生的な状態を維持することができる。
【0003】
しかし、前記構成の缶蓋によると、例えば、未開封の状態で前記缶容器を横倒させた場合等には、該缶容器内部の粉体食品が開口部を介して前記すりきり板部と前記シール部材との間の隙間に侵入することがある。そして、前記シール部材を剥離する開封操作を行なうと、前記すりきり板部と前記シール部材との間に侵入していた粉体食品が周囲に飛び散り、その飛び散った粉体食品の処理が煩わしい不都合があった。
【0004】
【発明が解決しようとする課題】
かかる不都合を解消して、本発明は、すりきり板部とシール部材との間への粉体食品の侵入を防止して、開封操作時の粉体食品の飛び散りを防止することができる缶蓋を提供することを目的とする。
【0005】
【課題を解決するための手段】
かかる目的を達成するために、本発明は、粉体食品を収容する缶容器を開口自在に閉塞する缶蓋であって、前記缶容器に巻締められるカール部と、該カール部の内方に形成されたパネル部と、該パネル部の一部に形成された開口部と、該パネル部の開口部の残部に形成され、該開口部に臨む直線状の端縁をすりきり縁とするすりきり板部と、前記パネル部の外周に沿って環状に設けられた第1の接着部を介して周縁部全周が剥離自在に接着され、前記パネル部のすりきり板部を覆うと共に前記開口部を閉塞するシート状のシール部材とを備え、前記シール部材は、前記すりきり板部のすりきり縁に沿って直線状に延設され且つ両端が前記第1の接着部と不連続とされた第2の接着部を介して該すりきり板部に剥離自在に接着され、該第2の接着部によって前記すりきり板部とシール部材との間に形成される空隙が封止されていることを特徴とする。
【0006】
本発明によれば、前記第2の接着部を設けたことにより、未開封状態にあるとき、前記シール部材によって覆われたすりきり板部がすりきり縁に沿って封止されている。これによって、例えば、前記缶容器が横倒しても、すりきり板部とシール部材との間に粉体食品が侵入することがなく、開封操作時における粉体食品の飛び散りを防止することができる。そして、前記シール部材は、前記第2の接着部を介してすりきり板部から剥離自在に接着されているので、前記第1の接着部の剥離時に前記第2の接着部を剥離させることができ、開封操作を容易に行なうことができる。
【0007】
また、本発明において、前記シール部材は、前記第1の接着部の外方に延出する剥離操作用のタブを備え、該タブを把持して該シール部材を前記第1の接着部を介して引き剥がすとき、該タブは、該シール部材の引き剥がし方向が、前記第2の接着部の延設方向に直交する線に対してずれた位置に設けられることを特徴とする。
【0008】
該缶蓋の開封作業を行なうときには、前記シール部材のタブを把持して引き上げることにより、該シール部材を前記第1の接着部に沿って剥離させて前記開口部を開放する。
【0009】
このとき、例えば、前記タブによるシール部材の引き剥がし方向が、前記第2の接着部の延設方向に直交していると、前記第2の接着部をその全長に亘って一挙に剥離させなければならない。そして、この場合には、タブからのシール部材の引っ張り力が第2の接着部の全長に亘って分散してしまい、該第2の接着部におけるシール部材の剥離が困難となる。
【0010】
それに対して、本発明においては、前記タブが、シール部材の引き剥がし方向が前記第2の接着部の延設方向に直交する線に対してずらして設けられているので、タブからの引っ張り力が、シール部材を介して前記第2の接着部の延設方向に対して角度をもって付与される。これにより、該引っ張り力が前記第2の接着部の一部に集中し、該第2の接着部の一端から他端に向って徐々に引き剥がされるので、該第2の接着部の剥離を容易に行なうことができる。
【0011】
【発明の実施の形態】
本発明の一実施形態を図面に基づいて説明する。図1は本実施形態の缶蓋を示す説明的平面図、図2は図1のII−II線断面図、図3は開封作業時のシール部材の状態を示す説明的平面図、図4は開封作業時のシール部材の他の状態を示す説明的平面図である。
【0012】
本実施形態の缶蓋1は、図1に示すように、平面視略円盤状に形成されており、粉乳等の粉体食品を内容物とする缶容器(図示せず)の上縁に巻締められる。該缶蓋1は、図1及び図2に示すように、前記缶容器に巻き締めるためのカール部2と、該カール部2の内方に形成されたパネル部3とを備えている。
【0013】
該パネル部3には、前記缶容器の内部から粉体食品を取り出すための大略半月状の開口部4が形成されている。該開口部4が形成されたパネル部3の残部には、該開口部4に臨む直線状の端縁をすりきり縁5とするすりきり板部6が形成されている。該すりきり縁5は、例えば、前記開口部4を介して計量スプーン(図示せず)により前記缶容器の内部から粉体食品を取り出すとき、該計量スプーン内の粉体食品のすりきり計量を行なうものである。
【0014】
また、前記パネル部3には、前記開口部4及び前記すりきり板部6を覆うシール部材7が設けられている。該シール部材7は、前記パネル部3の外周縁に沿って環状に***させて形成された環状凸部8の頂部に第1の接着部9を介して剥離自在に接着されている。
【0015】
更に、該シール部材7は、前記すりきり縁5に沿って設けられた直線状の第2の接着部10を介して前記すりきり板部6の上面に剥離自在に接着されている。これにより、図2に示すように、該すりきり板部6と前記シール部材7との間の空隙11が第2の接着部10によって封止される。なお、図1に示すように、前記第2の接着部10の両端が前記第1の接着部9の近傍に位置して該第1の接着部9と第2の接着部10とが不連続とされている。
【0016】
また、図1に示すように、前記シール部材7には、該シール部材7をパネル部3から剥離する際に把持するタブ12が設けられている。該タブ12は、シール部材7の外方に延設されているが、図1及び図2に示すように、シール部材7の上面に折返して重合され、カール部2の内方に収容されている。更に、該タブ12は、前記第2の接着部10の延設方向に直行して該缶蓋1の中央を通る線aに対して角度b(本実施形態においては45°±15°)を存して位置されている。
【0017】
以上のように構成された缶蓋1は、前記缶容器に巻締められたとき、前記シール部材7によって該缶容器を密封する。この状態で、例えば、缶容器が横倒しても、図2に示すように、前記第2の接着部10によって前記すりきり板部6と前記シール部材7との間の空隙11が封止されていることにより、該空隙11への粉体食品の侵入を防止することができる。
【0018】
そして、缶蓋1は、前記第1の接着部9及び前記第2の接着部10を介して前記シール部材7が剥離自在に接着されていることにより、図3に示すように、開封操作時に前記タブ12を把持して該シール部材7を引き剥がすだけで、容易に開口することができる。
【0019】
このとき、例えば、図4に示す他の缶蓋1´のように、前記第2の接着部10の延設方向に直行して該缶蓋1の中央を通る線a上に、前記タブ12が位置している場合には、第2の接着部10を剥離させるとき、該第2の接着部10をその全長に亘って一挙に剥離させることになり、比較的大きな引っ張り力が必要となる。それに対して、本実施形態においては、図1に示すように、前記タブ12が第2の接着部10の延設方向に直行して該缶蓋1の中央を通る線aに対して前記角度bをもって位置している。これにより、図3に示すように、第2の接着部10からシール部材7を引き剥がす過程で、該タブ12からのシール部材7の引っ張り力が前記第2の接着部10の一部に集中し、第2の接着部10の一端から他端にかけて徐々に剥離させることができるので、比較的小さな引っ張り力で円滑にシール部材7を引き剥がすことができる。

That is, this type of can lid includes a panel portion surrounded by a curl portion to be wound around the can container, and an opening portion formed by opening the panel portion in a substantially semilunar shape. In the panel portion, a ground plate portion is formed by a remaining portion of the opening portion, and a linear end edge facing the opening portion of the ground plate portion is the ground edge. Further, in this type of can lid, the opening is closed by a sheet-like sealing member in an unopened state. The seal member is detachably bonded along the outer peripheral edge of the panel portion through an annular bonding portion, and not only the opening but also the upper surface side of the ground plate portion is covered by the seal member It is said that. Thereby, in the unopened state, since the said board part is not exposed, contamination of this board part is prevented and a sanitary state can be maintained.
[0003]
However, according to the can lid of the above-described configuration, for example, when the can container is laid down in an unopened state, the powdered food inside the can container can be It may enter a gap between the sealing member. When the opening operation for peeling off the sealing member is performed, the powdered food that has entered between the scraping plate portion and the sealing member scatters around, and the processing of the scattered powdered food is troublesome. there were.
[0004]
[Problems to be solved by the invention]
In order to eliminate such inconvenience, the present invention provides a can lid that can prevent powdered food from entering between the scraping plate portion and the sealing member, and can prevent powdered food from scattering during the opening operation. The purpose is to provide.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a can lid for freely opening a can container for containing a powdered food, the curl portion being wound around the can container, and an inward side of the curl portion. A formed panel portion, an opening formed in a part of the panel portion, and a slit plate formed in a remaining portion of the opening portion of the panel portion and having a straight edge facing the opening as a ground edge And the entire periphery of the peripheral portion are detachably bonded via a first adhesive portion provided annularly along the outer periphery of the panel portion, covering the ground plate portion of the panel portion and closing the opening portion A sheet-like seal member that extends in a straight line along the scraped edge of the scraper plate portion, and a second adhesive having both ends discontinuous with the first adhesive portion. And is peelably bonded to the ground plate portion through the portion. Space formed between the leveling plate and the sealing member by parts is characterized in that it is sealed.
[0006]
According to the present invention, by providing the second adhesive portion, the ground plate portion covered with the seal member is sealed along the ground edge when in the unopened state. Thereby, for example, even if the can container is laid down, the powdered food does not enter between the scraping plate portion and the seal member, and the powdered food can be prevented from being scattered during the opening operation. And since the said sealing member is adhere | attached so that peeling from the grinding board part is possible via the said 2nd adhesion part, the said 2nd adhesion part can be peeled at the time of peeling of the said 1st adhesion part. The opening operation can be easily performed.
[0007]
Further, in the present invention, the seal member includes a tab for a peeling operation that extends outward from the first adhesive portion, and the seal member is held via the first adhesive portion by gripping the tab. When the tab is peeled off, the tab is provided at a position where the peeling direction of the seal member is shifted with respect to a line perpendicular to the extending direction of the second adhesive portion.
[0008]
When performing the opening operation of the can lid, the tab of the seal member is gripped and pulled up, whereby the seal member is peeled along the first adhesive portion to open the opening.
[0009]
At this time, for example, if the peeling direction of the sealing member by the tab is orthogonal to the extending direction of the second adhesive portion, the second adhesive portion must be peeled all at once over the entire length thereof. I must. In this case, the pulling force of the seal member from the tab is dispersed over the entire length of the second adhesive portion, making it difficult to peel off the seal member at the second adhesive portion.
[0010]
On the other hand, in the present invention, the tab is provided such that the peeling direction of the seal member is shifted with respect to the line perpendicular to the extending direction of the second adhesive portion, and therefore the pulling force from the tab Is applied at an angle with respect to the extending direction of the second adhesive portion via the seal member. As a result, the tensile force concentrates on a part of the second adhesive portion and is gradually peeled from one end to the other end of the second adhesive portion, so that the second adhesive portion is peeled off. It can be done easily.
[0011]

As shown in FIG. 1, the can lid 1 of the present embodiment is formed in a substantially disc shape in plan view, and is wound around the upper edge of a can container (not shown) containing powdered food such as milk powder. Tightened. As shown in FIGS. 1 and 2, the can lid 1 includes a curled portion 2 for tightening around the can container, and a panel portion 3 formed inside the curled portion 2.
[0013]
The panel portion 3 is formed with a substantially meniscal opening 4 for taking out powdered food from the inside of the can container. In the remaining portion of the panel portion 3 in which the opening 4 is formed, a scraping plate portion 6 having a straight edge facing the opening 4 as a scraping edge 5 is formed. For example, when the powdered food is taken out from the inside of the can by means of a measuring spoon (not shown) through the opening 4, the ground edge 5 is used to perform a ground measurement of the powdered food in the measuring spoon. It is.
[0014]
The panel portion 3 is provided with a seal member 7 that covers the opening 4 and the scraping plate portion 6. The seal member 7 is detachably bonded to a top portion of an annular convex portion 8 formed by protruding annularly along the outer peripheral edge of the panel portion 3 via a first adhesive portion 9.
[0015]
Further, the seal member 7 is detachably bonded to the upper surface of the scraping plate portion 6 via a linear second bonding portion 10 provided along the scraping edge 5. As a result, as shown in FIG. 2, the gap 11 between the scraping plate portion 6 and the seal member 7 is sealed by the second adhesive portion 10. As shown in FIG. 1, both ends of the second adhesive portion 10 are located in the vicinity of the first adhesive portion 9 so that the first adhesive portion 9 and the second adhesive portion 10 are discontinuous. It is said that.
[0016]
As shown in FIG. 1, the seal member 7 is provided with a tab 12 that is gripped when the seal member 7 is peeled from the panel portion 3. The tab 12 extends outward from the seal member 7, but as shown in FIGS. 1 and 2, the tab 12 is folded and superposed on the upper surface of the seal member 7 and accommodated inside the curl portion 2.

In this state, for example, even if the can container is laid down, as shown in FIG. 2, the gap 11 between the scraping plate portion 6 and the seal member 7 is sealed by the second adhesive portion 10. Thus, it is possible to prevent the powdered food from entering the gap 11.
[0018]
And, as shown in FIG. 3, the can lid 1 is opened during the opening operation because the seal member 7 is detachably bonded via the first adhesive portion 9 and the second adhesive portion 10. By simply grasping the tab 12 and peeling off the seal member 7, it can be easily opened.
[0019]
At this time, for example, like the other can lid 1 ′ shown in FIG. 4, the tab 12 is formed on a line a passing through the center of the can lid 1 and extending straight in the extending direction of the second adhesive portion 10. When the second adhesive portion 10 is peeled off, the second adhesive portion 10 is peeled at once over its entire length, and a relatively large tensile force is required. . On the other hand, in the present embodiment, as shown in FIG. 1, the tab 12 is perpendicular to the extending direction of the second adhesive portion 10 and the angle with respect to a line a passing through the center of the can lid 1. It is located with b. Thereby, as shown in FIG. 3, the pulling force of the seal member 7 from the tab 12 is concentrated on a part of the second adhesive portion 10 in the process of peeling the seal member 7 from the second adhesive portion 10. And since it can be made to peel gradually from the one end of the 2nd adhesion part 10 to the other end, seal member 7 can be smoothly peeled off by comparatively small pulling force.
