Description

本発明は、上側に開口部を有する軟質材料からなる再閉鎖可能な包装袋に関する。   The present invention relates to a reclosable packaging bag made of a soft material having an opening on the upper side.

再閉鎖可能な包装袋は多種多様な実施態様において知られている。また、粘着層を備えたフラップによって閉鎖される平ウェブから製造される包装袋も既にさまざまに知られている。特に、接着剤が過度に強く付着しないプラスチックから包装袋の少なくとも外層が構成される場合、そのような袋を何度も開封しまた再び閉鎖することに問題はない。側面折目を有する袋は、特に最初の開封後、開口縁を折り返すことによって再び閉鎖される。   Resealable packaging bags are known in a wide variety of embodiments. In addition, various packaging bags manufactured from a flat web closed by a flap provided with an adhesive layer are already known. In particular, if at least the outer layer of the packaging bag is made of a plastic to which the adhesive does not adhere too strongly, there is no problem with opening and closing the bag many times. Bags with side folds are closed again by folding the opening edge, especially after the first opening.

本発明の課題は、ごく簡単かつ安価に製造できる再閉鎖可能な包装袋を提案することである。   The object of the present invention is to propose a reclosable packaging bag that can be manufactured very simply and inexpensively.

この課題は、袋の片面に支持体が脱離不能に固着されており、粘着層を備えた軟質材料からなる切片がこの支持体上に脱離可能に固着されており、支持体の一部と切片の一部が袋の開口縁から突出していることを特徴とする包装袋によって解決される。   The problem is that the support is fixed to one side of the bag in a non-detachable manner, and a section made of a soft material having an adhesive layer is fixed to the support in a removable manner. And a part of the section protrudes from the opening edge of the bag.

本発明に係るこの解決の利点は特に、紙を含む任意の材料から袋を製造することができ、粘着切片を有する支持体が市販の粘着ラベルとすることができる点にある。   The advantage of this solution according to the invention is in particular that the bag can be manufactured from any material, including paper, and that the support with adhesive sections can be a commercially available adhesive label.

本発明の特別な実施態様によれば、支持体が分離線を有し、この分離線が弱化線として構成されまたは支持体を２つの部分に分割し、少なくとも近似的に開口縁と平行に延びている。そのことから、袋をはじめて閉鎖するとき、袋縁から突出する支持体部分の引き剥がしが容易となる。   According to a particular embodiment of the invention, the support has a separation line, which is configured as a weakening line or divides the support into two parts and extends at least approximately parallel to the opening edge. ing. For this reason, when the bag is closed for the first time, the support portion protruding from the bag edge can be easily peeled off.

本発明の他の実施態様によれば、支持体および／または切片が凹部を有し、この凹部が支持体の縁から延び、その頂点が分離線の領域にある。この設計は、袋をはじめて閉鎖するとき、袋と脱離不能に結合された部分から粘着切片が意図することなく引き剥がされるのを防止する。   According to another embodiment of the invention, the support and / or section has a recess, which extends from the edge of the support and whose apex is in the region of the separation line. This design prevents the adhesive section from being unintentionally pulled away from the part of the bag that is permanently attached to the bag when the bag is closed for the first time.

本発明の他の好ましい実施態様によれば、包装袋の軟質材料が少なくとも１つの紙層を有し、この紙層が包装袋の外面にあり、または軟質材料がそっくり紙からなる。本発明の他の好ましい実施態様によれば、袋が側面折目を有することができる。   According to another preferred embodiment of the invention, the soft material of the packaging bag has at least one paper layer, this paper layer is on the outer surface of the packaging bag, or the soft material is made entirely of paper. According to another preferred embodiment of the invention, the bag can have side folds.

最初の閉鎖後に包装袋が気密でなければならない場合、本発明の他の実施態様により袋の開口縁はシール縁として構成しておくことができる。   If the packaging bag must be airtight after the initial closure, the opening edge of the bag can be configured as a sealing edge according to another embodiment of the invention.

以下、添付図面を参考に本発明の特別な実施態様が詳しく説明される。   Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図１〜図６に示す袋はいわゆる角底袋である。しかし本発明は角底袋に限定されるものでなく、軟質材料からなるあらゆる種類の包装袋を含む。図１〜図４に示す包装袋は例えば紙から製造しておくことができ、紙は場合によっては袋の内面に薄いプラスチック層を備えており、この層が一定の気密性を保証し、かつシールによる材料の接合を可能とする。袋は裏面１と前面２とを有し、その側部は好ましくは周知の如くに側面折目３を有する。袋の下端に底４が形成され、上端には開口部５があり、この開口部を通して袋は詰められまた空にされる。   The bag shown in FIGS. 1-6 is what is called a square bottom bag. However, the present invention is not limited to square-bottom bags, but includes all types of packaging bags made of soft materials. The packaging bag shown in FIGS. 1 to 4 can be manufactured, for example, from paper, which in some cases is provided with a thin plastic layer on the inner surface of the bag, this layer guaranteeing a certain airtightness, and The material can be joined by a seal. The bag has a back surface 1 and a front surface 2, and its side preferably has side folds 3 as is well known. A bottom 4 is formed at the lower end of the bag and there is an opening 5 at the upper end through which the bag is packed and emptied.

袋の開口縁の近傍で開口縁を越えて裏面１に支持体６が持続的に固着され、例えば接着されまたはシールされている。支持体６は分離線７によって２つの部分８、９に区画されており、分離線７は図示例の場合袋の縁と正確に整列している。分離線７は支持体６の材料を完全に貫通することができ、または周知の如くに支持体の材料を完全には貫通しない弱化線として構成しておくことができる。粘着層を備えた軟質材料からなる切片が支持体６に付着している。本発明の特別好ましい実施態様によれば、この切片は市販の粘着ラベルであり、それゆえに以下の説明ではラベル１０と称される。支持体６はラベル１０に向き合う面にラベル１０の引き剥がしを可能とする層、いわゆる「剥離層」を備えている。   In the vicinity of the opening edge of the bag, the support 6 is permanently fixed to the back surface 1 beyond the opening edge, for example, bonded or sealed. The support 6 is divided into two parts 8, 9 by a separating line 7, which in the illustrated example is exactly aligned with the edge of the bag. The separation line 7 can penetrate the material of the support 6 completely or, as is well known, can be configured as a weakening line that does not penetrate the material of the support completely. A section made of a soft material having an adhesive layer is attached to the support 6. According to a particularly preferred embodiment of the invention, this section is a commercially available adhesive label and is therefore referred to as label 10 in the following description. The support 6 is provided with a layer that allows the label 10 to be peeled off on the surface facing the label 10, a so-called “peeling layer”.

図１が示す包装袋は包装製造業者から供給されて例えば食品加工工場に送り届けられるものであり、袋は工場ではじめて詰められる。図２が示す同じ袋はまっすぐに立てられ、詰め込み可能状態にあり、この図において袋は図１に示す状態に対して１８０°回して開口部５が十分に見えるようにしてある。詰め込み後にはじめて閉鎖する準備のために支持体６の袋縁から突出する部分８が引き剥がされ、この引き剥がしは分離線７によって容易とされる。この引き剥がし時に袋に強固に結合された支持体部分９から意図することなくラベルが引き剥がされ、部分８で引っ張られる方向が袋の前面２から裏面１に向かって延びる成分を有する場合特にそうであることが実験で判明した。これを防止するために、支持体６および／またはラベル１０の分離線７の領域に凹部１１が設けられていると有利であることが判明した。この凹部は図示したように円形としておくことができ、しかし公知の引裂き用切欠き等の鋭角形状を有することもできる。次のステップにおいてラベル１０の袋縁から突出する部分が折り曲げられ、支持体６の部分８を引き剥がすことによって露出するラベル１０の粘着層が袋の前面２に接着される。図３に示したようなこのような仕方で閉鎖された袋をいまや消費者に引き渡すことができる。   The packaging bag shown in FIG. 1 is supplied from a packaging manufacturer and sent to, for example, a food processing factory, and the bag is first packed in the factory. The same bag shown in FIG. 2 is upright and ready for stuffing, in which the bag is turned 180 ° relative to the state shown in FIG. 1 so that the opening 5 is fully visible. The part 8 protruding from the bag edge of the support 6 is peeled off in preparation for closing for the first time after stuffing, and this peeling is facilitated by the separating line 7. This is particularly the case when the label is unintentionally peeled off from the support portion 9 firmly bonded to the bag at the time of peeling, and the direction pulled by the portion 8 has a component extending from the front surface 2 to the back surface 1 of the bag. It was proved by experiment. In order to prevent this, it has proved advantageous if a recess 11 is provided in the region of the separating line 7 of the support 6 and / or the label 10. The recess can be circular as shown, but can also have an acute angle shape such as a known tear notch. In the next step, the portion of the label 10 protruding from the bag edge is bent, and the adhesive layer of the label 10 exposed by peeling off the portion 8 of the support 6 is adhered to the front surface 2 of the bag. A bag closed in this manner as shown in FIG. 3 can now be delivered to the consumer.

内容物を取り出すには、袋の裏面１のラベル１０と強固に結合されて前述の如くこの目的のために剥離層を有する支持体６の部分９からラベルを剥がすことによって、包装袋は簡単に開封することができる。図４は消費者が開封後の包装袋を示しており、図４の袋は図３の図示に対してやはり１８０°回してある。消費者が袋を再び閉鎖したい場合、消費者は図４の図示において袋縁から突出したラベル部分を支持体の向き合う袋縁にある部分９に再び単純に押し付ける。この過程を事実上任意に繰り返すことができることは自明である。   To remove the contents, the packaging bag can be easily removed by peeling off the label from the portion 9 of the support 6 which is firmly bonded to the label 10 on the back side 1 of the bag and has a release layer for this purpose as described above. Can be opened. FIG. 4 shows the packaging bag after opening by the consumer, and the bag of FIG. 4 is also rotated 180 ° relative to the illustration of FIG. If the consumer wants to close the bag again, the consumer simply presses again the label portion protruding from the bag edge in the illustration of FIG. 4 against the portion 9 on the opposite bag edge of the support. Obviously, this process can be repeated virtually arbitrarily.

上で説明した第１実施例による包装袋は気密に閉鎖することはできず、それゆえに当然に例えば液体成分を含有した内容物には適していない。この袋の主な使用目的は、例えば飛行機の乗客に引き渡すように指定された例えばサンドイッチ等の固形食品の包装にある。   The packaging bag according to the first embodiment described above cannot be hermetically closed and is therefore of course not suitable for contents containing, for example, liquid components. The main purpose of use of this bag is in the packaging of solid foods such as sandwiches, which are designated for delivery to airplane passengers, for example.

図５と図６に示す本発明の第２実施例は最初の閉鎖後の気密な包装袋を示す。このため、この袋は最初に詰めるとき周知の如くにシール縁１２によって閉鎖される。支持体６はこの袋の裏面１に、シール縁１２に付着しないように固着されている。それゆえにこの袋の最初の開封はシール縁１２の引裂きによって簡単に行うことができ、これは引裂き用切欠き１３によっておよび／または包装材料に設けられる図示しない弱化線によって容易とすることができる。こうして開封された袋を消費者が再び閉鎖したい場合、消費者は図６に示唆したように支持体６の部分８をラベル１０から引き剥がし、袋開口部５の上にラベルの突出部分を置き、突出部分を袋の前面２に接着する。この袋を２回目に開封するとき利用者は、図４に関連して先に述べたように、支持体６の「剥離層」を備えて袋の裏面１に配置される部分９からラベル１０を引き剥がす。   The second embodiment of the invention shown in FIGS. 5 and 6 shows an airtight packaging bag after the initial closure. For this reason, the bag is closed by the seal edge 12 as is known when first packed. The support 6 is fixed to the back surface 1 of the bag so as not to adhere to the seal edge 12. Thus, the initial opening of the bag can be easily accomplished by tearing the seal edge 12, which can be facilitated by the tear notch 13 and / or by a weakening line (not shown) provided in the packaging material. If the consumer wants to re-open the bag thus opened, the consumer peels off the portion 8 of the support 6 from the label 10 as suggested in FIG. 6 and places the protruding portion of the label over the bag opening 5. The protruding portion is bonded to the front surface 2 of the bag. When the bag is opened for the second time, the user can label 10 from the portion 9 provided on the back surface 1 of the bag with the “peeling layer” of the support 6 as described above with reference to FIG. Tear off.

最後に図７と図８は本発明による包装袋用のラベルを有する支持体材料の条片の一部をそれぞれ示す。両方の事例において本発明に係る包装袋を製造するためにエンドレス帯の態様の支持体６が使用され、この支持体上にラベル１０が一列に貼り付けられている。分離線７と凹部１１もこの条片に既に設けておくことができる。図７の条片はチューブ体から袋を製造するために設けられており、袋の開口縁は製造方向を横切って延びている。図８の条片は単数または複数のウェブから袋を製造するのに使用され、開口縁は例えばウェブの縁でウェブ方向と平行である。   Finally, FIGS. 7 and 8 show part of a strip of support material having a label for a packaging bag according to the invention, respectively. In both cases, a support 6 in the form of an endless band is used to produce a packaging bag according to the invention, on which labels 10 are applied in a row. A separation line 7 and a recess 11 can also already be provided in this strip. The strip of FIG. 7 is provided for manufacturing a bag from a tube body, and the opening edge of the bag extends across the manufacturing direction. The strip of FIG. 8 is used to make a bag from one or more webs, the opening edges being parallel to the web direction, for example at the edges of the web.

ラベル１０は、上で説明した実施例に述べられた実質的に長方形形状ではなく、任意に形成しておくことができる。ラベルは例えば単数または複数の耳片を備えておくこともでき、この耳片が開封を容易とする。さらに、ラベルは任意の材料で構成し、例えば透明または透光性としておくことができる。ラベルは印刷し、例えば目的および／または使用指示に関する表示を備えておくことができる。ラベルは周知の如くに包装内容物の賞味期限に関する表示も当然に含むことができる。支持体６に関しても同じことがあてはまる。例えば、取り去られる部分８は使用指示および／または耳片を有することができる。支持体６の袋に残る部分９にはラベル１０の下に袋再閉鎖指示を印刷しておくことができ、この指示は袋の開封後にはじめて現れる。   The label 10 is not substantially rectangular as described in the embodiment described above, but can be formed arbitrarily. The label may be provided with, for example, one or more ear pieces that facilitate opening. Furthermore, the label can be made of any material, for example, transparent or translucent. The label can be printed and provided with an indication regarding the purpose and / or instructions for use, for example. As is well known, the label can naturally include an indication regarding the expiration date of the package contents. The same applies for the support 6. For example, the removed part 8 can have instructions for use and / or ear pieces. A portion 9 of the support 6 remaining in the bag can be printed with a bag reclose instruction under the label 10 and this instruction appears only after the bag is opened.
