[Selection] FIG.

Description

本発明は、紙パック容器の開封器具に関する。   The present invention relates to an opening device for a paper pack container.

従来、牛乳、ジュース、お茶等の飲料や醤油、酒等の内溶液を封入した紙パック容器が知られているが（図６を参照）、この紙パック容器Ｐの開封にあたっては、開閉部３４、３４を開き、左右両側から手で強く押すことにより、開封口４０、４０を開口させ、折込部３９を前方に引き出して注ぎ口を形成していた。
しかしながら、接着部３５、３５によって封止された開閉部３４、３４の外側折合せ部３６、３６と内側折合せ部３７、３７とを剥離させるためには、相当の力を要し、特に老人、女性、子供あるいは手に障害をもった人等に大きな負担を強いるものであった。 Conventionally, a paper pack container in which a solution such as milk, juice, tea or the like, or a soy sauce, liquor or the like is enclosed is known (see FIG. 6). , 34 is opened and pressed firmly by hand from the left and right sides to open the opening 40, 40, and the folding portion 39 is pulled forward to form a spout.
However, in order to peel off the outer folding parts 36 and 36 and the inner folding parts 37 and 37 of the opening and closing parts 34 and 34 sealed by the adhesive parts 35 and 35, a considerable amount of force is required. It puts a heavy burden on women, children or people with disabilities in their hands.

また、上記によっては、折込部３９を前方に引き出せないような場合には、接着部３５、３５を爪でこじあけ指先を入れて、外側折合せ部３６、３６と内側折合せ部３７、３７とを剥離させていたが、この剥離作業が実に困難をきわめるものであり、接着部３５、３５が綺麗に剥がれずに破損し、うまく開封口４０、４０を開口させることができないという問題があった。   In addition, depending on the above, when the folding part 39 cannot be pulled forward, the adhesive parts 35 and 35 are removed with a nail and the fingertips are inserted, and the outer folding parts 36 and 36 and the inner folding parts 37 and 37 However, this peeling operation is extremely difficult, and there is a problem that the adhesive portions 35 and 35 are not peeled cleanly and are damaged, and the opening 40 or 40 cannot be opened properly. .

これに対して、このような紙パック容器Ｐの開封作業を支援する器具としては、これまでに下記特許文献１乃至３に記載されるタイプのものが提案されている。   On the other hand, as a device for supporting the opening operation of such a paper pack container P, the types described in the following Patent Documents 1 to 3 have been proposed.

実開平４−６５７１４4-65714 実開昭５６−１４４７４３Japanese Utility Model Sho 56-144743 特開２００４−１１５１２２JP 2004-115122 A

ところが、上記特許文献１に記載されるものは、断面視略楔状に形成された「オプナー」を用いて、単に開閉部３４、３４を左右に切り開くようにしたにすぎず、上記問題を解決するには至っていない。
一方、上記特許文献２乃至３に記載されるものは、何れも爪状片を折込頂部３９’近辺の接着部３５に任意に挿入して前方に引っ張ることで、外側折合せ部３６、３６と内側折合せ部３７、３７とを剥離させるようにしているため、爪状片の挿入部位や挿入深度の設定、あるいは力の入れ加減が難しく、特に折込頂部３９’近辺は構造的にも弱いことから、依然として接着部３５を破損させてしまいがちであり、簡単に操作を行うことができないものであった。また、爪状片を折込頂部３９’近辺に過度に挿入してしまうことで、食品衛生上も問題があった。 However, what is described in Patent Document 1 merely solves the above problem by simply opening and closing the open / close sections 34 and 34 using an "opner" formed in a substantially wedge shape in cross section. It has not reached.
On the other hand, in all of the above-mentioned Patent Documents 2 to 3, the nail-like pieces are arbitrarily inserted into the adhesive portion 35 in the vicinity of the folding top portion 39 ′ and pulled forward, so that the outer folding portions 36, 36 and Since the inner folding portions 37 and 37 are peeled off, it is difficult to set the insertion site and insertion depth of the nail-shaped piece, or to adjust the force, especially in the vicinity of the folding top portion 39 '. Therefore, the adhesive portion 35 still tends to be damaged, and the operation cannot be easily performed. In addition, there is a problem in food hygiene because the nail-like piece is excessively inserted in the vicinity of the folding top 39 '.

そこで、本発明は、上記問題に鑑みてなされたものであり、きわめて簡単に操作でき、非常に小さな力で、誰にでも容易に、且つ綺麗に紙パック容器の開封を行うことのできる紙パック容器の開封器具を提供することを目的としている。   Therefore, the present invention has been made in view of the above problems, and is a paper pack that can be operated very easily and can be opened easily and cleanly by anyone with a very small force.

開封器具１の紙パック容器Ｐへの装着が完了した後は、上記によって形成された接着部３５、３５の切り込み４１、４１を押し広げるための動作を行う。この動作としては、一方の手で紙パック容器Ｐを支えながら、他方の手で把手２を前方に傾動させるだけでよい。
すると、図１１に示すように、紙パック容器Ｐの屋根状部３１、３１の後端縁が、開封クリップ３の折返し部２３、２３によって上方に持ち上げられる作用とも相俟って、紙パック容器Ｐの封緘部３２の中央頂部５０近傍が、開封クリップ３の挟着部１１’の下端前部４５’によって押し下げられるとともに、開閉部３４、３４の外側折合せ部３６、３６が、開封クリップ３の挿入部２０、２０によって押し下げられ、切り込み４１、４１が押し広げられることで、開口５５が形成されることとなる。 After the attachment of the opening device 1 to the paper pack container P is completed, an operation for expanding the notches 41 and 41 of the adhesive portions 35 and 35 formed as described above is performed. As this operation, it is only necessary to tilt the handle 2 forward with the other hand while supporting the paper pack container P with one hand.
Then, as shown in FIG. 11, in combination with the action that the rear end edges of the roof-like portions 31, 31 of the paper pack container P are lifted upward by the folded portions 23, 23 of the opening clip 3, The vicinity of the central top portion 50 of the P sealing portion 32 is pushed down by the lower end front portion 45 ′ of the sandwiching portion 11 ′ of the opening clip 3, and the outer folding portions 36 and 36 of the opening and closing portions 34 and 34 are opened by the opening clip 3. The insertion portions 20 and 20 are pushed down and the notches 41 and 41 are pushed and widened to form an opening 55.

このとき特に、外側折合せ部３６、３６の中央頂部５０周辺を、内側折合せ部３７、３７の折込頂部３９’周辺から剥離させる力が作用するため、図１１〜図１２に示すように、開口５５を、折込頂部３９’周辺を含み、且つ接着部３５を内外に連通したものとして形成できる。   At this time, in particular, because the force that peels the periphery of the central top 50 of the outer folding part 36, 36 from the vicinity of the folding top 39 'of the inner folding part 37, 37 acts, as shown in FIGS. The opening 55 can be formed so as to include the periphery of the folding top portion 39 ′ and communicate the adhesive portion 35 in and out.

さらに、本実施形態に係る開封器具１には係止部４６が備えられており、図１１に示すように、把手２の傾動に従って、係止部４６が紙パック容器Ｐの封緘部３２の後端縁５１を押圧し、後端縁５１を前方に傾動させるとともに封緘部３２の中央頂部５０を下方に移動させるモーメント力を作用させるため、より一層小さい力で切り込み４１、４１を押し広げて、開口５５を形成することができる。
しかも、挟着部１１’の下端には端面４５が形成されており、紙パック容器Ｐの封緘部３２の略後半部における上端縁３２’に略全面的に当接可能であるため、上記の係止部４６とともに、封緘部３２の略後半部を確実にホールドすることができる。 Furthermore, the opening device 1 according to the present embodiment is provided with a locking portion 46, and the locking portion 46 is provided behind the sealing portion 32 of the paper pack container P as the handle 2 tilts as shown in FIG. 11. In order to press the end edge 51, tilt the rear end edge 51 forward, and apply a moment force that moves the central top 50 of the sealing portion 32 downward, the notches 41 and 41 are spread with a smaller force, An opening 55 can be formed.
In addition, an end face 45 is formed at the lower end of the sandwiching portion 11 ′, and can substantially abut against the upper end edge 32 ′ in the substantially rear half of the sealing portion 32 of the paper pack container P. Together with the locking part 46, the substantially second half part of the sealing part 32 can be reliably held.

また、開封クリップ３の胴部１５、１５の前部には、所定形状の切欠部１８、１８が形成されているため、開閉部３４、３４の外側折合せ部３６、３６との衝突が阻止され、把手２の傾動に伴う胴部１５、１５の前方へのスムーズな傾動が妨げられないようになっている。   Moreover, since the notch parts 18 and 18 of predetermined shape are formed in the front part of the trunk | drum parts 15 and 15 of the opening clip 3, the collision with the outer side folding parts 36 and 36 of the opening-and-closing parts 34 and 34 is prevented. Thus, the smooth tilting forward of the body portions 15 and 15 accompanying the tilting of the handle 2 is not hindered.

なお、図８に示すように、挿入部２０を接着部３５へ差し込んだ際に、挿入部２０の斜辺２０’が、開封口４０の形成する直線となるべく小さい角度（好ましくは１５〜４５度程度）をなすように構成することが好ましい。そのような構成であれば、挿入部２０が接着部３５内で面的に当接することとなって、開封口４０に沿う切り込み４１の幅を大きくとることができ、接着部３５を剥離やせ易いものとできる。   As shown in FIG. 8, when the insertion portion 20 is inserted into the adhesive portion 35, the oblique side 20 ′ of the insertion portion 20 is as small as possible as a straight line formed by the opening 40 (preferably about 15 to 45 degrees). ) Is preferable. If it is such a structure, the insertion part 20 will contact | abut in surface in the adhesion part 35, and the width | variety of the notch 41 along the opening 40 can be taken large, and it will be easy to peel off the adhesion part 35 I can do it.

上記によって切り込み４１、４１を押し広げ、所定の開口５５を形成した後は、開封器具１をもとの垂直な状態に戻した上で、紙パック容器Ｐから取り外す。すると、図１２に示すように、紙パック容器Ｐの折込み頂部３９’からその左右にかけて開口５５が形成された状態を得ることができる。   After the notches 41 and 41 are spread by the above and the predetermined opening 55 is formed, the opening device 1 is returned to the original vertical state and then removed from the paper pack container P. Then, as shown in FIG. 12, it is possible to obtain a state in which the opening 55 is formed from the folded top portion 39 'of the paper pack container P to the left and right.

そして、さらに図１２に示すように、開閉部３４、３４を前方に引っ張るが、開口５５が、上記した通り、折込頂部３９’周辺を含み、且つ接着部３５を内外に連通して形成されているため、開閉部３４、３４に左右両側から僅かな力を手で加えてやるだけで、きわめて簡単に、外側折合せ部３６、３６から内側折合せ部３７、３７を剥離させ、折込部３９および折込頂部３９’を前方に突出させて注ぎ口５６を形成することができる。   Further, as shown in FIG. 12, the opening / closing portions 34 are pulled forward, and the opening 55 is formed so as to include the periphery of the folding top portion 39 'and communicate the adhesive portion 35 inside and outside as described above. Therefore, the inner folding portions 37, 37 are peeled off from the outer folding portions 36, 36 very simply by applying a slight force to the opening / closing portions 34, 34 from both the left and right sides. Further, the spout 56 can be formed by projecting the folding top 39 'forward.

以上、本実施形態に係る開封器具１によれば、開閉部３４、３４が所定の状態となされた紙パック容器Ｐに開封クリップ３を装着し、把手２を前方に傾動させるだけで、開閉部３４、３４の接着部３５、３５に所定の開口５５を形成することができるため、きわめて操作が簡単である。しかも、把手２に加えられる力が非常に小さいものであっても、梃子の原理および上記した開封クリップ３の構造によって、紙パック容器Ｐに有効な力を作用させることができ、老人、女性、子供あるいは手に障害をもった人等でも容易に開封作業を行える。   As described above, according to the opening instrument 1 according to the present embodiment, the opening / closing portion 34, 34 is attached to the paper pack container P in a predetermined state, and the opening / closing portion is simply tilted forward. Since the predetermined opening 55 can be formed in the adhesive portions 35, 35 of the 34, 34, the operation is extremely simple. Moreover, even if the force applied to the handle 2 is very small, an effective force can be applied to the paper pack container P by the principle of the lever and the structure of the opening clip 3 described above. Even a child or a person with a handicapped hand can easily perform the opening operation.

また、折込頂部３９’近辺に爪状片を任意に挿入する従来のものと違って、誰が操作しても略一定の開口５５を形成できるとともに、折込頂部３９’近辺の接着部３５を破損させるおそれもなく、外側折合せ部３６、３６と内側折合せ部３７、３７とを非常に綺麗に剥離させることができる。そして、挿入部２０、２０が、折込頂部３９’から離れた位置で、且つ適度に差し込まれるため、食品衛生上も問題がない。   Further, unlike the conventional one in which a claw-like piece is arbitrarily inserted in the vicinity of the folding top portion 39 ′, a substantially constant opening 55 can be formed by anyone, and the adhesive portion 35 in the vicinity of the folding top portion 39 ′ is damaged. Without fear, the outer folded portions 36 and 36 and the inner folded portions 37 and 37 can be peeled off very finely. And since the insertion parts 20 and 20 are inserted moderately in the position away from the folding top part 39 ', there is no problem in food hygiene.

なお、第１スペース７および第２スペース８、８の構成について、紙パック容器Ｐの封緘部３２および屋根状部３１、３１をそれぞれ密嵌する構成とすることもできるが、より好ましくは、本発明により期待される作用効果を失わない範囲内で、これらを遊びのある状態（例えば１〜２ｍｍのクリアランス）で嵌め入れるように構成する。そのような構成であれば、開封器具１の紙パック容器Ｐへの着脱が容易に行えるものとなる。また、把手２の一部に永久磁石を埋設した構成としてもよい。この場合、冷蔵庫の扉等所望の場所に開封器具１を磁着保持させておくことが可能となり、必要なときに見つけ出し易く、利便性が向上する。   In addition, about the structure of the 1st space 7 and the 2nd space 8 and 8, it can also be set as the structure which closely fits the sealing part 32 and the roof-like parts 31 and 31 of the paper pack container P, respectively, More preferably, this These are configured so as to be fitted in a playable state (for example, a clearance of 1 to 2 mm) within a range not losing the effects expected by the invention. If it is such a structure, the attachment or detachment to the paper pack container P of the opening instrument 1 can be performed easily. Further, a configuration in which a permanent magnet is embedded in a part of the handle 2 may be adopted. In this case, it becomes possible to magnetically hold the opening device 1 at a desired place such as a refrigerator door, so that it is easy to find out when necessary and convenience is improved.

以上の実施形態の記述は、本発明をこれに限定するものではなく、本発明の要旨を逸脱しない範囲で種々の設計変更等が可能である。   The description of the above embodiment does not limit the present invention, and various design changes and the like can be made without departing from the gist of the present invention.
