A joint joined so as to at least partially close the strip may be formed transverse to the strip. The joint may be formed shorter than the width of the strip.
The method of forming the joint is not particularly limited. For example, heat sealing, an adhesive, a hot melt, etc. can be suitably selected according to the material of a thin film.
The shape of the joint is not particularly limited. When a tray is used, it is preferable that the shape of the end of the tray conform to the shape of the joint. By doing this, the tray is locked at the joint portion in the housing space, and the movement of the tray can be restricted.

Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.
Example 1
(1) Configuration of Packaging Bag The packaging bag 1 of Example 1 extends in the longitudinal direction of the strip 7 provided with double thin films 3 and 5 (see FIGS. 2 and 3) as shown in FIGS. Both end portions 9, 9 are closed to form a housing space 11 (see FIGS. 3 and 4) between the both end portions 9, 9. A first grip 13 and a second grip 15 are formed at both ends of the strip 7 in the longitudinal direction. One end 7A of the strip 7 in the longitudinal direction is opened to be an opening 17 (see FIG. 4). A joint 19 is formed at a position closer to the second grip 15 than the longitudinal center of the strip 7 so as to at least partially close the strip 7. The joint 19 functions as a proximal end of the second grip 15 (see FIG. 6).

For the strip 7, thin films 3 and 5 of high density polyethylene with a thickness of 30 μm are used. The thin films 3 and 5 are translucent so that the inside of the storage space 11 is difficult to see. As shown in FIG. 1, the strip 7 is in the form of a strip having substantially the same width. As shown in FIG. 5, the width of the strip 7 is such that the tray 21 can be inserted into the accommodation space 11, and is set to be slightly larger than the width of the tray 21.
The band 7 is an integral member formed by crushing a tube manufactured using inflation molding. Therefore, as shown in FIG. 3, both side ends 9 and 9 are closed in advance during film formation, and it is not necessary to perform closing again.
The length L of the strip 7 is set as follows. That is, as shown in FIG. 6, the tray 21 is put in the housing space 11, and the first gripping portion 13 and the second gripping portion 15 are picked up upward, and the hole 13A of the first gripping portion 13 and the second gripping portion The length L of the strip 7 is set so that fingers can be placed on both of the fifteen holes 15A. Preferably, it is set as the following formula (1). Here, L indicates the length of the strip 7 and L _T indicates the length of the tray 21 (see FIGS. 1 and 4).

(Expression 1) 2.5 × L _T ≦ L ≦ 5.0 × L _T

The first grip portion 13 has a corner cut off and has a substantially trapezoidal shape. The tip of the second grip portion 15 is also cut off to form a substantially trapezoidal shape.
As shown in FIG. 1, at the other end 7 </ b > B in the longitudinal direction of the strip 7, a joint (second joint) 23 joined by heat sealing is formed. The bonding portion 23 prevents the double thin films 3 and 5 of the second grip portion 15 from being separated and the handling property being lowered.

(2) Effects of Packaging Bag As shown in FIG. 4, the user first widens the opening 17 of the packaging bag 1. Then, a substantially square tray 21 on which an article 27 such as bread is placed is inserted into the storage space 11 from the opening 17. Then, the end of the tray 21 is locked to the joint 19 and stopped as shown in FIG. From this state, as shown in FIG. 6, the first gripping portion 13 and the second gripping portion 15 are lifted to align the first gripping portion 13 and the second gripping portion 15. The joint portion 19 functions as a proximal end of the second grip portion 15 and contributes to shape maintenance of the second grip portion 15.
Then, the hole 13A of the first grip 13 and the hole 15A of the second grip 15 overlap with each other. In this state, the first gripping portion 13 and the second gripping portion 15 have a form like a triangular roof (gable roof). Subsequently, when a hand is put in the hole 13A of the first grip 13 and the hole 15A of the second grip 15, the tray 21 on which the articles 27 are placed can be lifted in a state of being surrounded by the packaging bag 1. At this time, the tray 21 is preferably substantially horizontal.

In the packaging bag 1 of the first embodiment, the tray 21 is inserted from the open end 7A. Then, the user holds the first grip 13 and the second grip 15 by hand. Then, the second grip portion 15 is lifted with the joint portion 23 as the base end, and the form of the second grip portion 15 is stabilized, so that the handling is easy.
The tray 21 on which the articles 27 are placed is inserted from one end and locked to the joint 19. As a result, the position of the tray 21 is regulated, so that the tray 21 can be packaged in a stable state.
The joint 19 is shaped in accordance with the form of the portion of the tray 21 to be locked. That is, in the case of the first embodiment, since the shape is substantially linear and is along the end of the tray 21, the tray 21 is well locked to the joint portion 19 and becomes difficult to shift. The position is more stable.

In the first embodiment, the tip end portions of the first gripping portion 13 and the second gripping portion 15 have a substantially trapezoidal shape. Assuming that the first gripping portion 13 and the second gripping portion 15 have a substantially rectangular shape, in this case, the corners of the substantially rectangular shape come into contact with the hand, which lowers the operability. In the present embodiment, since the corner portion has a substantially trapezoidal shape dropped, the corner portion does not touch the hand and operability is improved.
In the first embodiment, when the user slides the tray 21 from the opening 17 of the packaging bag 1 into the storage space 11 and lifts the first gripping portion 13 and the second gripping portion 15, packaging is completed. Do. As described above, when the packaging bag 1 of the first embodiment is used, the packaging operation can be performed easily and quickly. It is particularly useful in stores where quickness of packaging is required (e.g., a store in a station, a store in an airport, a store in a service area, etc.).
Moreover, in Example 1, since the form after packaging becomes a form which formed the triangular roof (gable roof) above the tray 21, it is excellent also in design.
Further, in Example 1, since the thin films 3 and 5 of high density polyethylene are used, the strength as the packaging bag 1 is also sufficient. Furthermore, since the semitransparent thin films 3 and 5 are used, the presence or absence of the article 27 can be confirmed, but the details of the article 27 can not be confirmed, so that the privacy of the user can be considered.

Moreover, the packaging bag 1 is an integral body formed by crushing the tube manufactured using inflation molding. Therefore, the process of joining two separate thin films is unnecessary, and the productivity of the packaging bag 1 is high.
Moreover, in the packaging bag 1 of Example 1, since the tray 21 is accommodated in a substantially horizontal state between the first gripping portion 13 and the second gripping portion 15, the article 27 is placed on the tray 21 while being maintained. It can be transported stably.
Moreover, since the packaging bag 1 of Example 1 is an integral body formed by crushing a tube, it can be stored as a non-bulk state before use.

<Description of other usage conditions>
Next, another usage of the packaging bag 1 according to the first embodiment will be described with reference to FIG. Note that, in FIG. 7, the same components as those in the first embodiment are denoted by the same reference numerals, and the description of the structure, operation, and effect is omitted. In FIG. 7, the configuration of the packaging bag 1 is substantially the same as that of the first embodiment, but the form of the tray 21 to be accommodated is different. The tray 21 has a circular shallow dish shape. For example, sushi, hors d'oeuvres and the like are provided on the tray 21.
