  The present invention provides a packaging bag for home delivery or mailing that has a simple structure, has a buffering function, can easily separate an outer bag and a synthetic resin inner bag at the time of disposal, and can be provided at low cost. About.

  Conventionally, as a packaging bag for home delivery or mail, a packaging bag made of a paper outer bag and an inner bag made of a synthetic resin bubble cushioning material is used to protect the stored items. There are various types. The inner bag is fixed through various fixing means so as not to peel off or come off from the outer bag.

  As the fixing means, an adhesive is often used or heat welding is performed by heat sealing. Further, the bonding range between the bags on the outer side and the inner side is performed over substantially the whole or around the opening of both bags. In particular, the adhesion between the outer bag and the inner bag by heat sealing is particularly strong. There exists patent document 1 as this kind of thing.

JP 2008-110815 A

  This type of packaging bag separates the external paper bag from the synthetic resin bubble cushioning material from the viewpoint of environmental protection, etc., for disposal when it is used up. However, they must be separated and discarded. For this reason, various developments have been made to facilitate the separation of the paper outer bag and the synthetic resin inner bag. As an example, Japanese Patent Application Laid-Open No. H10-228561 discloses a device that facilitates separation by separately using a fixing portion (heat seal) by heat welding and a fixing portion by an adhesive.

  However, the adhesive force is actually very strong in the heat welded portion. Moreover, even if it is based on an adhesive, although the adhesive strength is somewhat lower than that of the heat-sealed (heat-sealed) portion, generally the adhesive strength is still quite strong. Furthermore, in the heat-sealed (heat-sealed) portion, even if the paper-side outer bag and the synthetic-resin-side bag are peeled off, the paper-made bag has a portion of the synthetic-resin bag. Some remain and cannot be completely separated.

  In this type of packaging bag, the stored items are stored in a bag made of a synthetic resin bubble cushioning material on the inner side. Therefore, in this type of packaging bag, there is a problem that the storage space is reduced by the inner bag made of the bubble cushioning material. For example, the product to be stored and the instructions, invoices, and other documents are stored together. Can be very cumbersome. In particular, in the case of work for storing a large number of deliveries of documents of the same type, such as merchandise and instructions, for home delivery, the work efficiency is extremely poor.

  Therefore, the technical problem (purpose) to be solved by the present invention is to facilitate the separation work between the outer bag made of paper and the inner bag made of a synthetic resin-made bubble cushioning material and to store the stored items. The purpose is to improve the efficiency.

  According to a sixth aspect of the present invention, in any one of the first, second, third, fourth and fifth aspects, the bubble cushioning sheet material constituting the inner bag has a base sheet and a bulge having a large number of small bulges. The above-mentioned problems have been solved by adopting a two-layer type consisting of a delivery sheet and using the outer surface side of the inner bag as a packaging bag body for home delivery or mail as the base sheet.

  A seventh aspect of the present invention is the foam cushioning sheet material constituting the inner bag according to any one of the first, second, third, fourth, and fifth aspects, wherein the bubble cushioning sheet material includes a base sheet and a large number of small bulges. The above-mentioned problem has been solved by adopting a two-layer type consisting of a delivery sheet, and using the inner side of the inner bag as a packaging bag for home delivery or mail as the base sheet.

  According to an eighth aspect of the present invention, in any one of the first, second, third, fourth and fifth aspects, the bubble cushioning sheet material constituting the inner bag has a base sheet and a bulge having a large number of small bulges. It is a two-layer type consisting of an exit sheet, and the outer surface side of either the front surface portion or the back surface portion of the inner bag is a base sheet, and the other outer surface side is the small bulge portion for home delivery or mailing. The above-mentioned problem was solved by using a packaging bag body.

  According to a ninth aspect of the present invention, in any one of the first, second, third, fourth and fifth aspects, the bubble cushioning sheet material constituting the inner bag is a bulge having a base sheet and a large number of small bulges. A three-layer type consisting of an exit sheet and a cover sheet that covers a small bulge portion of the bulge sheet, and either home delivery or mailing with either the base sheet or the cover sheet as the outer surface side of the inner bag The above-mentioned problems have been solved by using a packaging bag body.

  In the first aspect of the present invention, the inner bag is housed in the outer bag, and the surface constituent portions of the outer bag and the inner bag are disposed in the vicinity of both the opening portions and horizontally through the surface-side adhesive tape. And the back surface constituent parts of the outer bag and the inner bag are bonded to each other through the back surface side adhesive tape arranged vertically in the vicinity of both openings and in the range from the center to the end in the width direction. This is a configuration.

  That is, the inner bag is bonded to the outer bag by the surface side adhesive tape arranged horizontally on the surface side, and the back surface components are bonded by the back surface side adhesive tape arranged vertically. Thus, one of the front surface side adhesive tape and the back surface side adhesive tape is horizontal, and the other is arranged vertically, and the outer bag and the inner bag are bonded to each other.

  Therefore, the inner bag has a horizontal adhesive structure in the vicinity of the opening with respect to the outer bag, and the inner surface of the inner bag has a vertical adhesive structure from the vicinity of the opening toward the bottom. The bag can be stored in a stable state in the horizontal and vertical directions with respect to the outer bag.

  Further, the outer bag and the inner bag are partially bonded by the front surface side adhesive tape and the back surface side adhesive tape, and the bonded area is a small portion when viewed from the whole packaging bag. Therefore, the work of peeling off the inner bag from the outer bag can be achieved by holding the bottom of the inner bag with the hand of the operator and dragging the bottom of the inner bag to the outside as it is. It can be easily separated.

  That is, as described above, the inner bag has a surface-side adhesive tape that adheres the surface constituent parts to the outer bag in a horizontal manner, and the back-side adhesive tape that adheres the back constituent parts is vertical. It is set as the structure arrange | positioned in a shape. Therefore, when the inner bag is peeled off from the outer bag and separated, the back side adhesive tape follows the direction in which the inner bag is pulled out of the outer bag, and the back side adhesive tape becomes the outer bag and the inner bag. It will be easy to peel off.

  When the inner bag is completely separated from the outer bag at the final stage of the peeling operation, only the adhesive portion between the outer bag and the surface constituent parts of the inner bag is left by the surface side adhesive tape. The force required for peeling off the bag can be reduced, and this makes it very easy to separate the outer bag and the inner bag.

  Furthermore, the back component parts of the outer bag and the inner bag are bonded to each other via the back surface side adhesive tape arranged vertically in the vicinity of both openings and in the range from the center in the width direction to the end part. Thus, a storage space can be provided between the back surface constituent portions of the outer bag and the inner bag.

  And, inside the inner bag, store goods such as products, and insert documents such as product manuals, invoices, catalogs, etc. in the space between the back side components of the outer bag and the inner bag. This has the advantage that the goods and documents can be stored separately in the packaging bag.

  Furthermore, the back surface side adhesive tape is arrange | positioned perpendicularly | vertically in the range near the edge part from the center of the width direction near back opening parts between both opening parts. With such a configuration, the packaging bag body is placed on the work desk with the front surface side down, and the back surface constituent portion of the inner bag is lifted together with the back surface side adhesive tape.

  At this time, the back surface constituent part of the inner bag is not bonded to the outer bag over the entire width direction, but only a part in the width direction is attached to the back surface constituent part of the outer bag by the back side adhesive tape. It is in a state of being bonded. Therefore, although the back surface component of the inner bag is lifted together with the back surface component of the outer bag, as the back surface component of the outer bag rises high, the weight of the back surface component of the inner bag A gap is generated between the back surface components.

  This portion becomes a storage portion suitable for inserting a document such as a product manual, an invoice or a catalog. Moreover, since the opening part of an inner bag also opens while a clearance gap produces between the back surface components of an outer bag and an inner bag, it can easily accommodate stored goods, such as goods. Furthermore, since the back-side adhesive tape is arranged vertically, it can also serve as an insertion guide when storing the document storage in the gap between the back-surface components of the outer bag and the inner bag.

  In the invention of claim 2, the back side adhesive tape has a range of less than half of the dimension in the vertical direction of the outer bag and the inner bag, thereby reducing the bonding range and separating the outer bag and the inner bag. Can be done easily. In the invention of claim 3, the back side adhesive tape maintains the inner bag in an extremely stable state with respect to the outer bag by setting the back side adhesive tape in a range exceeding half of the vertical dimension of the outer bag and the inner bag. can do.

  In the invention of claim 4, the bottom portion of the outer bag and the inner bag is a square bottom, so that the storage volume can be increased. With regard to the invention of claim 5 as well, it is possible to increase the storage volume by forming the gusset portions on both sides in the width direction of the outer bag and the inner bag.

  In addition, if the front side adhesive tape and the rear side adhesive tape are both arranged horizontally, the outer bag and the inner bag can be firmly bonded, and the front side adhesive tape and the rear side are near both openings. Adhesive tape is arranged and the bottom of the inner bag is in a free state that is not constrained by the outer bag. Therefore, the bottom of the inner bag can be easily grasped, and the separation operation between the outer bag and the inner bag can be facilitated. .

  Furthermore, if the front surface side adhesive tape and the back surface side adhesive tape are arranged over the entire width direction of the outer bag and the inner bag, the adhesive strength between the outer bag and the inner bag can be further strengthened.

In the invention of claim 6 , the foam cushioning sheet material constituting the inner bag is a two-layer type comprising a base sheet and a bulging sheet having a number of small bulging portions, and the outer surface side of the inner bag is the base sheet. By doing so, it becomes a surface contact structure which a base sheet opposes to the inner surface side of the outer bag 1, and it can carry out adhesion | attachment of surface structure parts and back surface structure parts easily with a surface side adhesive tape and a back surface side adhesive tape. Further, since the small bulging portion is located on the inner surface side of the inner bag, the stored item such as a product stored in the inner bag and the small bulging portion come into contact with each other, and the shape and impact of the stored item are reduced. Can be better protected.

In the invention of claim 7 , the foam cushioning sheet material constituting the inner bag is a two-layer type comprising a base sheet and a bulging sheet having a number of small bulging portions, and the inner surface side of the inner bag is the base sheet. Accordingly, the base sheet is positioned on the inner surface side of the inner bag, and the bulging sheet having the small bulging portion is positioned on the outer surface side of the inner bag. And in a state where the inner bag is housed in the outer bag, the base sheet is positioned on the inner surface side of the inner bag, and the small bulge portion is positioned on the outer surface side. With such a configuration, the base sheet serving as a flat surface is positioned on the inner surface side of the inner bag, and the storage of the stored items in the inner bag can be facilitated.

In the invention of claim 8 , the bubble cushioning sheet material constituting the inner bag is a two-layer type comprising a base sheet and a bulging sheet having a number of small bulging portions, and the surface constituting portion and the back surface constitution of the inner bag. Since the outer surface side of any one of the parts is a base sheet and the other outer surface side is the small bulging part, the structure of the inner surface side differs between the front surface configuration part and the back surface configuration part of the inner bag. .

  And when the outer surface side of the inner bag is a base sheet, the adhesive force with the inner surface side of the outer bag by the double-sided tape (front surface side adhesive tape or back surface side adhesive tape) can be increased, and the outer surface side of the inner bag is In the case of the small bulging portion, the adhesive force with the inner surface side of the outer bag by the double-sided tape (front surface side adhesive tape or back surface side adhesive tape) can be reduced. As a result, the adhesive force between the outer bag and the inner bag can be set to an appropriate state, and the inner bag can be peeled off from the outer bag relatively easily.

In the invention of claim 9 , the bubble cushioning sheet material constituting the inner bag includes a base sheet, a bulging sheet having a large number of small bulging portions, and a cover sheet covering the small bulging portions of the bulging sheet. The inner layer side of the outer bag and the outer surface side of the inner bag are both flat surfaces by using either the base sheet or the cover sheet as the outer surface side of the inner bag. The adhesive force with the inner surface side of the outer bag by the double-sided tape (front surface side adhesive tape or back surface side adhesive tape) can be increased. Moreover, since the inner surface side of the inner bag also becomes a base sheet or a cover sheet and becomes a flat surface, it is possible to smoothly put in and out the stored items.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The structure of this invention consists of the outer bag 1, the inner bag 2 which consists of the foam cushion sheet S, and the surface side adhesive tape 3 and the back surface side adhesive tape 4 which made the both surfaces into the adhesive surface. In the present invention, there are a plurality of embodiments. In the first embodiment, the outer bag 1 is made of paper, and the bag portion is formed from the front surface configuration portion 11, the back surface configuration portion 12, the bottom portion 13, and the gusset portions 14, 14. The sealing part 15 used as the lid | cover of the outer bag 1 is formed in the upper end of the said surface structure part 11 (refer FIG. 1). The sealing portion 15 is generally called a tongue.

  The front surface constituting portion 11, the back surface constituting portion 12, the bottom portion 13, the gusset portions 14 and 14, and the sealing portion 15 are formed from one paper material or a plurality of paper materials. The front surface configuration portion 11 and the back surface configuration portion 12 are formed in a rectangular shape such as a rectangle or a square, and the gusset portions 14 and 14 and the bottom portion 13 are formed in a rectangular shape. An opening 1 a is located above the outer bag 1.

  According to the above configuration, the outer bag 1 is of the square bottom bag type, but the envelope type in which the gusset portions 14 and 14 are not formed, or the gusset portions 14 and 14 are formed and the bottom portion 13 is formed. It includes a straight gusset type instead of a square bottom.

  Here, the outer bag 1 has a front side and a back side. This is a name used for convenience of explanation, the front side is the side on which the sealing part 15 is formed (see FIG. 1B), and the back side is formed by the sealing part 15. This is the side that is not performed (see FIG. 1C). However, without being limited thereto, the front side surface of the outer bag 1 may be used as a back side surface, and the back side may be used as a front side.

  Next, the inner bag 2 is formed from the bubble buffering sheet material S of a synthetic resin. Similarly to the outer bag 1, the inner bag 2 is also composed of a front surface configuration portion 21, a back surface configuration portion 22, a bottom portion 23, and gusset portions 24 and 24. Further, the sealing portion 15 of the outer bag 1 is not formed on the inner bag 2. The opening 2a is located above the inner bag 2. And, the inner bag 2 has one or more front surface constituent parts 21, rear surface constituent parts 22, bottom parts 23, gusset parts 24, and sealing parts 15. It is formed from the bubble buffer sheet material S.

The bubble cushioning sheet material S is made of a material such as a polyethylene sheet, and is formed with a large number of small bulging portions p, p,... Filled with cylindrical or hemispherical air. A base sheet S1 as a base and a bulging sheet S2 formed with a large number of small bulging portions p, p,... Are formed on the base sheet S1 by fusing the bulging sheet S2 to the base sheet S1. Many small bulges p, p, ...
Is formed as a two-layer type (see FIGS. 3B and 3C).

Further, the base sheet S1 includes a bulging sheet S2 having a large number of small bulging portions p, p,... And a cover sheet S3. The small bulging portions p, p,. A structure having a sandwich structure sandwiched between S1 and cover sheet S3 and in which small bulging portions p, p,... Are not exposed on both the front and back surfaces of bubble cushioning sheet material S is referred to as a three-layer type [FIGS. )reference〕.

  As the bubble cushioning sheet material S constituting the inner bag 2 in the present invention, either a two-layer type or a three-layer type can be used. And when using the two-layer type bubble buffer sheet material S for the inner bag 2, there are three usage examples shown below. First, in the first usage example, the base sheet S1 is positioned on the outer surface side of the inner bag 2, and the bulging sheet S2 having the small bulging portions p, p,... Is positioned on the inner surface side of the inner bag 2. [See FIGS. 3A and 3B].

In this first usage example, when the inner bag 2 is housed in the outer bag 1, the base sheet S 1 has a surface contact configuration facing the inner surface side of the outer bag 1, and the front surface side adhesive tape 3 and the back surface side adhesive tape 4. Thus, it is possible to easily bond the front surface constituent parts 11 and 21 and the back surface constituent parts 12 and 22 together. Further, since the small bulging portions p, p,... Are positioned on the inner surface side of the inner bag 2, the stored items such as products stored in the inner bag 2 and the small bulging portions p, p,. It will contact, and the shape of a stored item and the protection against an impact can be made favorable.

Next, in the second usage example, the base sheet S1 is positioned on the inner surface side of the inner bag 2, and the bulging sheet S2 having the small bulging portions p, p,... Is positioned on the outer surface side of the inner bag 2. This is a configuration (see FIG. 3C). In this second usage example, the base sheet S1 is located on the inner surface side of the inner bag 2 and the small bulging portions p, p,. . With such a configuration, the base sheet S1 having a flat surface is positioned on the inner surface side of the inner bag 2, and the storage of the storage items in the inner bag 2 can be facilitated.

Moreover, in the 3rd usage example, the structure of the inner surface side differs in the surface structure part 21 and the back surface structure part 22 of the inner bag 2, respectively. Specifically, in the surface constituent part 21 of the inner bag 2, the base sheet S1 is the outer surface side, and the bulging sheet S2 having the small bulging parts p, p,. 22, the base sheet S1 is the inner surface side of the inner bag 2, and the bulging sheet S2 having small bulging portions p, p,... Is the outer surface side (see FIGS. 3D and 3E). Although not particularly illustrated, as a configuration opposite to the third usage example described above, the base sheet S1 is the inner surface side of the inner bag 2 at the surface constituting portion 21 of the inner bag 2, and the base sheet S1 is formed at the rear surface constituting portion 22. May be the outer surface side of the inner bag 2.

In this third usage example, the small bulging portions p, p,... Are located on the outer surface side of either the front surface portion 21 or the back surface portion 22 of the inner bag 2, and the other outer surface is a flat base sheet S1. Will be located. And when the outer surface side of the inner bag 2 becomes the base sheet S1, the adhesive force with the inner surface side of the outer bag 1 by a double-sided tape (the surface side adhesive tape 3 or the back surface side adhesive tape 4) can be enlarged.

  Moreover, when the outer surface side of the inner bag 2 becomes the small bulging portions p, p,..., The adhesive force between the inner surface side of the outer bag 1 by the double-sided tape (the front surface side adhesive tape 3 or the back surface side adhesive tape 4) is reduced. can do. As a result, the adhesive force between the outer bag 1 and the inner bag 2 can be set to an appropriate state, and the inner bag 2 can be peeled off from the outer bag 1 relatively easily.

In the three-layer type bubble cushioning sheet material S3, the bulging sheet S2 is sandwiched between the base sheet S1 and the cover sheet S2, and the base sheet S1 and the cover sheet S2 are both flat surfaces. Therefore, in the inner bag 2 using the three-layer type bubble cushioning sheet material S, the inner surface side and the outer surface side are the same surface.

Thereby, the inner surface side of the outer bag 1 and the outer surface side of the inner bag 2 are both flat surfaces, and the inner surface side of the outer bag 1 by the double-sided tape (the front surface side adhesive tape 3 or the back surface side adhesive tape 4). The adhesive force of can be increased. Moreover, since the inner surface side of the inner bag 2 also becomes the base sheet S1 or the cover sheet S2 and becomes a flat surface, it is possible to smoothly put in and out the stored items.

  As described above, the outer bag 1 is of a square bottom bag type, but as other types, an envelope type in which the gusset portions 14 and 14 are not formed, or the gusset portions 14 and 14 are provided. There is a gusset type that is formed and the bottom 13 is not a square bottom but a straight line. And the inner bag 2 is made into the same structure according to the shape of this outer bag 1 corresponding to the various types of the outer bag 1 mentioned above.

  In the following description, both the outer bag 1 and the inner bag 2 are described as a square bottom type (see FIGS. 1A, 2A, 2B, and 4A). Further, in both the outer bag 1 and the inner bag 2, the side where the openings 1a and 2a are located is the upper side, and the width direction of the square-shaped surface constituent parts 11 and 12 (or the back surface constituent parts 12 and 22) is the horizontal direction. The vertical direction is the vertical direction. The width direction (horizontal direction) and the vertical direction (vertical direction) are described in the main diagram.

  The outer bag 1 and the inner bag 2 have substantially the same shape as described above. However, since the inner bag 2 is housed in the outer bag 1, the inner bag 2 may be slightly smaller in volume than the outer bag 1. Good. First, the inner bag 2 is built in the outer bag 1. At this time, the outer bag 1 and the inner bag 2 are arranged so that the front surface constituent parts 11 and 21 and the rear surface constituent parts 12 and 22 face each other [FIG. 1 (A), FIG. 2 (A), ( B) etc.].

And the surface structure parts 11 and 12 of the outer bag 1 and the inner bag 2 are surface-side adhesive tape 3 arrange | positioned horizontally along the width direction in the vicinity of both opening parts 1a and 2a, and the surface of the outer bag 1 The component part 11 and the surface component part 21 of the inner bag 2 are affixed [refer FIG. 1 (B), FIG. 2 (A), (B)]. The surface-side adhesive tape 3 is a double-sided tape having both surfaces as adhesive surfaces.

  Further, the back surface side adhesive portions 4 are arranged in the vertical direction in the vicinity of both openings 1a and 2a and in the range from the center (center) position in the width direction to the end in the width direction. Are arranged vertically, and the back surface constituting portion 12 of the outer bag 1 and the back surface constituting portion 22 of the inner bag 2 are attached [see FIG. 1 (B), FIG. 2 (A), (B). ].

  Here, as described above, the position where the back surface side adhesive tape 4 is arranged is between the center position (center) in the width direction of the back surface constituent parts 12 and 22 and the position of the end portion in the width direction. It is the range m, and the back surface side adhesive tape 4 is arranged vertically within the range m. In particular, the back surface side adhesive tape 4 is preferably disposed at an intermediate position within the range m. Further, the back-side adhesive tape 4 may be disposed near the center (center) position L or at the center (center) position L within the range m.

  Further, the back-side adhesive tape 4 is in a range that is less than half of the vertical dimension of the outer bag 1 and the inner bag 2 (see FIG. 8B), or the upper and lower sides of the outer bag 1 and the inner bag 2. The range may exceed half of the dimension in the direction (see FIGS. 1A and 1C).

  The usage method of 1st Embodiment of this invention is demonstrated. First, the packaging bag of the present invention is placed on the work table with the front side facing down (see FIG. 5A). And the surface structure part 11 of the outer bag 1 is pressed with one hand, and the opening part 1a vicinity of the back surface structure part 12 is lifted with the other hand (refer FIG. 5 (A)). At this time, the back surface structure part 22 of the inner bag 2 rises with the back surface side adhesive tape 4 [refer FIG. 5 (B)].

  Furthermore, when the back surface constituting portion 12 of the outer bag 1 is lifted, the back surface constituting portion 22 of the inner bag 2 is also lifted, but the back surface side adhesive tape 4 is within the range near the center and the end in the width direction of the back surface constituting portion 12. For this reason, the back surface constituting portion 22 of the inner bag 2 does not rise over the entire width direction. Therefore, a gap T is generated between the back surface constituting portion 12 of the outer bag 1 and the back surface constituting portion 22 of the inner bag 2.

  This gap T is formed on the side opposite to the position of the back surface side adhesive tape 4 and closer to the end from the center in the width direction of the surface constituent part 11 of the outer bag 1 and the surface constituent part 21 of the inner bag 2. [Refer to FIG. 5 (C) and FIG. 6 (A)]. First, the product storage 5 is put in the inner bag 2, and the document storage 6 is inserted and stored in the gap T (see FIGS. 6B and 6C).

  When the present invention has been used, put the hand into the inner bag 2 of the packaging bag body of the present invention, grasp the bottom 23 of the inner bag 2, and drag it out of the outer bag 1 as it is. The inner bag 2 is separated and discarded as separated waste.

  Next, a third embodiment of the present invention will be described. In this 3rd Embodiment, as shown in FIG. 9, it is comprised from the outer bag 1, the inner bag 2, the surface side adhesive tape 3, and the back surface side adhesive tape 4. As shown in FIG. The inner bag 2 is housed in the outer bag 1, and the front surface constituent parts 11, 21 and the rear surface constituent parts 12, 22 of the outer bag 1 and the inner bag 2 are both openings 1 a, 2 a.
