Abstract

<P>PROBLEM TO BE SOLVED: To provide a reclosable bag which has an opening with a zipper arranged in a front panel thereof in an inclined direction. <P>SOLUTION: The reclosable bag is formed by providing a web-like front sheet 12 having the inclined opening 14. The inclined opening is provided with the zipper 30. The inclined opening is typically arranged at a 45 degree angle with respect to an upper seal 20, but it may be arranged at an angle ranging from 30 to 60 degrees. The reclosable bag may be formed by arranging the web having the inclined opening beforehand, or the inclined opening may be formed in a full-surface sheet 12, in one step in the process of producing the bag. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明はジッパ付きの傾斜開口部を前面パネルに有した柔軟な袋（パウチ）に関する。   The present invention relates to a flexible bag (pouch) having an inclined opening with a zipper in a front panel.

従来技術において、再閉鎖可能なバッグは、典型的に正方形または長方形に形成され、開口部すなわちジッパ付きの開口部が、バッグの辺に対して平行または垂直に設けられている。この構成は、種々の先行文献に記載されているが、１９９９年９月１４日にイエガー（Ｙｅａｇｅｒ）に付与された米国特許第５９５１４５３号「再閉鎖可能なバッグ集成体およびその製造方法」や、２００１年８月７日にイエガーに付与された米国特許第６２７０２５７号「開口部を改良した輪郭形成ストリップ締結具を備えた再閉鎖可能なバッグ」に典型的な再閉鎖可能なバッグが示されている。   In the prior art, reclosable bags are typically formed in a square or rectangular shape, with openings or zippered openings provided parallel or perpendicular to the sides of the bag. This configuration has been described in various prior documents, including US Pat. No. 5,951,453, entitled “Reclosable Bag Assembly and Method for Producing the Same,” granted to Yeager on September 14, 1999, A typical reclosable bag is shown in U.S. Pat. No. 6,270,257, "Reclosable Bag with Contoured Strip Fastener with Improved Opening" issued to Jaeger on August 7, 2001. Yes.

然しながら、機能的な理由または美観上の理由からジッパを斜めに設けることが望ましいこともある。   However, it may be desirable to provide the zipper diagonally for functional or aesthetic reasons.

米国特許第５９５１４５３号明細書US Pat. No. 5,951,453 米国特許第６２７０２５７号明細書US Pat. No. 6,270,257

本発明の目的は、ジッパ付き開口部が再閉鎖可能なバッグの前面パネルに斜めの方向に設けられている再閉鎖可能なバッグを提供することである。   An object of the present invention is to provide a reclosable bag in which a zippered opening is provided in an oblique direction on the front panel of the reclosable bag.

本発明は、ジッパ付き開口部が再閉鎖可能なバッグの前面パネルに斜めの方向に設けられている再閉鎖可能なバッグの製造方法を提供することを更に目的としている。   Another object of the present invention is to provide a method for manufacturing a reclosable bag in which the zippered opening is provided in an oblique direction on the front panel of the reclosable bag.

これらの目的および他の目的は、バッグの上縁部に対して３０度〜６０度の範囲の角度、典型的には４５度の角度をなすようにジッパ付き開口部を形成した再閉鎖可能なバッグによって達成される。製造方法は、所望の傾斜角度で予め形成されジッパを取付けるべき開口部を備えたウェブを用い、適当に融着することによって再閉鎖可能なバッグが製造される。   These and other purposes are reclosable with a zippered opening formed at an angle in the range of 30 to 60 degrees with respect to the upper edge of the bag, typically 45 degrees. Accomplished with a bag. The manufacturing method uses a web that is pre-formed at a desired inclination angle and has an opening to which a zipper is to be attached, and a bag that can be reclosed is manufactured by fusing appropriately.

以下、添付図面を参照して本発明の実施形態を説明するが、添付図面において同様の構成要素には同じ参照番号が付されている。
図１は、本発明の再閉鎖可能なバッグの正面図である。再閉鎖可能なバッグ１０は、ウェブ状の前面シート１２と、ウェブ状の背面シート１６（前面シート１２の背後に示されている）から形成されており、前面シート１２には傾斜開口部１４が形成されている。前面シート１２および背面シート１６は、上シール部２０、サイドシール部２２、２４および底シール部２６により接合されている。当業者には理解されるように、前面シート１２および背面シート１６は、ウェブ状の単一のシートから形成することができ、その場合、シール部２０、２２、２４、２６の１つは折曲げ部により置換される。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals are given to the same components.
FIG. 1 is a front view of the reclosable bag of the present invention. The reclosable bag 10 is formed from a web-like front sheet 12 and a web-like back sheet 16 (shown behind the front sheet 12), which has an inclined opening 14 in the front sheet 12. Is formed. The front sheet 12 and the back sheet 16 are joined by an upper seal part 20, side seal parts 22, 24 and a bottom seal part 26. As will be appreciated by those skilled in the art, the front sheet 12 and the back sheet 16 can be formed from a single web-like sheet, in which case one of the seals 20, 22, 24, 26 is folded. Replaced by the bend.

傾斜開口部１４にはサイドシール部２２または上シール部２０から４５度の方向に延びるように図示されている。しかし、傾斜開口部１４は、サイドシール部２２から３０度から６０度の角度の方向に、かつ、上シール部２０に関しては相補的な角度を以て配向することができる。   The inclined opening portion 14 is illustrated so as to extend in the direction of 45 degrees from the side seal portion 22 or the upper seal portion 20. However, the inclined opening 14 can be oriented in the direction of an angle of 30 to 60 degrees from the side seal portion 22 and with a complementary angle with respect to the upper seal portion 20.

傾斜開口部１４はジッパ３０を具備し、該ジッパは、典型的には、輪郭形成部材３２、３４と、再閉鎖可能なバッグ１０を選択的に開閉可能とするスライダとを含む。これにより、利用者は、開口部１４を開いて、食品等の再閉鎖可能なバッグ１０の内容物を取出すことが可能となる。   The inclined opening 14 includes a zipper 30, which typically includes contouring members 32, 34 and a slider that allows the reclosable bag 10 to be selectively opened and closed. Thereby, the user can open the opening part 14 and take out the contents of the bag 10 that can be closed again such as food.

図２は、ウェブ供給源１１０から供給されるウェブ１００を示している。該ウェブには、一連の傾斜開口部１４が一定間隔で予め形成されている。或は、バッグ１０を製造するプロセス中に、ウェブ１００に傾斜開口部１４を切断することによって、ウェブ１００の位置決めを単純化するようにしてもい。ウェブ１００は、最終的には前面シート１２を形成する。シール部２０、２２、２４、２５が形成された後に背面シート１６となるように、製袋充填シールプロセスの間、切欠のないウェブから成る別のシート（図示せず）を供給するようにしてもよい。また、ウェブ１００は、縁部１０２、１０４を合わせ接合することにより、サイドシール部２２が形成可能なように（サイドシール部２４は折曲げ部により置換される）十分な幅を有するようにしてもい。   FIG. 2 shows a web 100 supplied from a web source 110. The web is pre-formed with a series of inclined openings 14 at regular intervals. Alternatively, the positioning of the web 100 may be simplified by cutting the inclined openings 14 in the web 100 during the process of manufacturing the bag 10. The web 100 ultimately forms the front sheet 12. During the bag-filling sealing process, another sheet of uncut web (not shown) is supplied so that it becomes the back sheet 16 after the seals 20, 22, 24, 25 are formed. Also good. Further, the web 100 has a sufficient width so that the side seal portion 22 can be formed by joining the edge portions 102 and 104 together (the side seal portion 24 is replaced by a bent portion). Yes.

こうして、既述した目的および利点が最も効果的に達成される。本発明の好ましい実施形態を詳細に説明したが、本発明はこれに限定されず、特許請求の範囲によって規定されることは言うまでもない。   Thus, the stated objectives and advantages are most effectively achieved. Although preferred embodiments of the present invention have been described in detail, it is needless to say that the present invention is not limited thereto and is defined by the claims.
