Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a packaging bag provided with a re-openable / closable jig near an opening.

[0002]

[Prior art]

 As shown in FIG. 4, a packaging bag provided with a concave / convex articulation tool conventionally provided generally has knobs 14 and 14 provided above a concave / convex articulation tool 13 attached near an opening 12 of a bag body 11. Have been.

[0003] When the opening 12 is opened, the engagement of the concavo-convex articulation tool 13 is released by picking the knob pieces 14, 14 with a fingertip and pulling the knob pieces 14 right and left.

[0004]

[Problems to be solved by the invention]

 However, according to the conventional packaging bag, if the concave and convex jaws 13 are released many times, the tabs 14 and 14 are stretched and deformed, so that smooth release of the engagement cannot be performed.

Further, when the bag body 11 is a thin film, there is a problem that the tab 14 is torn while the concave and convex jaws 13 are being released many times.

In addition, since the inner surfaces of the portions that are the knobs 14 are in close contact with each other, there is also a problem that it is difficult to put the contents contained in the bag body 11 through the opening 12.

[0007] The present invention has been made to solve the above-described problems, and it is possible to smoothly release the occlusal tool, and it is possible to easily put the contents through the opening. An object of the present invention is to provide a packaging bag with a snapper.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the invention of claim 1 according to the invention is provided with an occlusal tool 3 which is sealed on both sides 9 and 9 and which can be opened and closed again in the vicinity of the opening 2 and comprises a synthetic resin sheet. In the bag body 1 formed by the above, the upper ends of the pair of sheet pieces 5, 5 extending above the jig 3 are bent so that the double portions 6, 6 of the sheet pieces are bent. Is formed, and the double part 6,6 constitutes the tabs 4,4 when the jig 3 is opened and closed. In this way, the upper ends of the sheet pieces 5, 5 are bent to form a double portion, and the double portions constitute the knobs 4, 4, thereby forming a knob with one sheet. And the knobs can be formed firmly.

Further, in the packaging bag with a jaw according to the present invention, at least the lower end of the double part 6,6 of the sheet piece is sealed, and the tabs 4,4 are provided. This is preferable because the knobs 4, 4 can be stiff and the contents to be accommodated in the bag body 1 can be easily taken in and out of the opening.

[0010] In the packaging bag with the occlusal tool according to the present invention, the double portions 6, 6 of the sheet pieces are embossed to form the knob pieces 4, 4, as described in claim 3. This is preferable because the knobs 4, 4 can be stiff and the contents to be stored in the bag body 1 can be easily taken in and out from the opening 2.

In addition, the packaging bag with an articulation tool according to the present invention is provided with an articulation tool 3 that is sealed on both sides 9 and 9 and that can be opened and closed again in the vicinity of the opening 2. In the bag body 1 formed of a resin sheet, the upper ends of a pair of sheet pieces 5, 5 extending above the jaws 3 are embossed to open and close the jaws 3. It is characterized in that the knob pieces 4, 4 at the time are formed. Since the upper ends of the sheet pieces 5 and 5 are embossed in this way, the knobs 4 and 4 have sufficient stiffness, so that a single sheet can be used as a durable knob 4 and 4. Can be formed.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a packaging bag with a jaw according to the present invention, and FIG. 2 is a sectional view taken along line AA of FIG.

In FIGS. 1 and 2, reference numeral 1 denotes a bag body for storing contents such as food. In the bag body 1, a single rectangular sheet made of a synthetic resin is bent into approximately half, the bent end is used as a bottom 8, and the other open end is used as an opening. 2, and both sides 9, 9 are heat-sealed to form a bag.

On the upper part of the bag body 1, jaws 3, 3 composed of a male jaw and a female jaw which are engaged with each other are formed integrally with the seat. Further, sheet pieces 5, 5 are provided above and below the sheet pieces 3, 5, respectively.

Here, as shown in FIG. 2, the sheet pieces 5, 5 are formed with double portions 6, 6, which are bent from the upper end thereof to form a double portion. Adhesive 7 is applied and fixed to form knobs 4, 4 for gripping when disengagement of jaws 3, 3.

The packaging bag configured as described above is provided with tabs 4, 4 at both ends of a sheet on which jaws 3, 3 having a male jaw and a female jaw as a pair are formed in advance. After forming the sheet 4, the sheet is formed by heat-sealing both sides 9, 9 of the sheet.

In the packaging bag formed as described above, since the tabs 4, 4 are formed of a double sheet, the tabs 4, 4 are strong and stiff, and the opening 2 is opened. In doing so, the knobs 4, 4 are gripped with fingertips, and are not stretched or torn even when pulled to the right and left, and the engaged jaws 3, 3 can be easily opened.

Further, since the packaging bag can be formed from one sheet, manufacturing can be facilitated.

In the above-described embodiment, an adhesive is applied to the entire surface of the double portion 6, 6 which is a bent portion at the upper end of the sheet pieces 5, 5, and the whole is sealed. If an adhesive is applied to a part (preferably the lower end) of the part, it is enough to fix the double part 6,6. And, since the double portions 6, 6 are sealed and fixed, the contents contained therein can be easily put in and taken out from the opening 2.

Note that the sealing method is not limited to the above-described adhesion by applying an adhesive, and may be, for example, heat sealing.

In addition, by embossing the double parts 6, 6 in place of the seals to form the tabs 4, 4, the tabs 4, 4 are provided with sufficient stiffness and formed to be strong. The knob can be opened and closed smoothly without damaging the knob even if the jig is opened and closed many times, and when the opening is opened and the contents are stored, the knob is firm. Therefore, the contents can be easily introduced without the inner surfaces of the picking pieces being in close contact with each other as in the related art.

In the above embodiment, the upper ends of the sheet pieces 5, 5 are double-folded to form the double portions 6, 6, so that the knobs 4, 4 are firmly formed with a stiffness. However, as shown in FIG. 3, the tabs 4, 4 may be formed by embossing the upper ends of the sheet pieces 5, 5.

By embossing the sheet pieces 5, 5, the tabs 4, 4 can be given a sufficient stiffness, and the tough tabs 4, 4 can be formed.

[0024]

[Effect of the invention]

 According to the packaging bag of the present invention, since the tabs can be formed by one sheet, the production can be facilitated.

In addition, the tab can be formed to be strong, so that it can be comfortably used without being torn or stretched even when the engagement of the jig is released many times.
