Description

  The present invention relates to the sealing performance of a sealing bag.

  Conventional sealing bags are equipped with synthetic resin chucks facing each other in order to enable sealing on both inner sides near the mouth of the bag. The entrance and exit of air was blocked to enable sealing. When the contents are powdery, the contents are taken out with a spoon, or the bag is tilted.

For example, the techniques described above are disclosed in Patent Documents 1 to 4.
Japanese Patent No. 2699217 JP 2003-175945 A Japanese Utility Model Publication No. 06-059237 Japanese Patent Laid-Open No. 06-286759

  The chuck of the sealing bag had a groove, and sealing was possible by engaging these. However, when the content is taken out by tilting the sealed bag, the content moves while sliding inside the sealed bag. At this time, the contents pass over the chuck groove. At that time, if the contents were powdery, the contents were clogged in the chuck groove. Even if the chuck is engaged while the contents are jammed, a gap is generated in the chuck groove portion, resulting in a decrease in the airtightness of the sealing bag.

  If the chuck is repeatedly engaged while the contents are stuck in the groove of the chuck, the amount of the contents jammed in the groove increases, and at the same time, the contents jammed in the groove are compressed by the pressure when the chuck is engaged. It becomes hard. Since the hardened contents fill the chuck groove, the chuck cannot be engaged and the sealing bag cannot be closed.

  Further, the contents attached to the outside of the chuck portion do not return to the bag, and remain as they are unless wiped off. This is not hygienic and increases the loss of contents.

  The present invention is intended to solve such a conventional problem, and prevents the contents from clogging in the groove portion of the chuck, and at the same time facilitates the removal of the contents.

  The present invention solves the above problem by attaching a sheet for covering the groove of the chuck inside the chuck of the sealing bag to the inside of the sealing bag. Some sheets are also provided with a knob for facilitating development.

  According to the present invention, after the sealing bag is opened, the inside sheet is taken out, and the contents are passed over the sheet and taken out, so that the contents do not adhere to the chuck portion, so that a good sealed state is maintained.

  Further, if the sheet is outside the opening, the contents are not left on the opening side after the sealing after the sealing, so that loss of the contents can be suppressed, and further safety can be improved hygienically. .

  Hereinafter, a sealing bag according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the sealed bag 1 of the present embodiment includes a synthetic resin bag body 2, a synthetic resin chuck 3 provided in the vicinity of the opening of the bag body 2, and the bag body 2. The sheet 4 is provided further inside than the chuck 3.

  The chuck 3 has a groove for engaging, and the inside of the bag body 2 can be sealed by pressing the chuck from one end to the other end with a finger from the outside of the sealing bag. The bag body 2 has a bag shape formed by bonding three sides of two sheets of synthetic resin. The sheet 4 has an adhesive surface 6 for bonding to the bag body 2, a knob 7 for facilitating deployment of the sheet 4 outward from the bag body 2, and a hinge portion 8 for smooth deployment of the sheet 4.

  The sheet 4 is formed in a pentagonal shape, its width is slightly shorter than the lateral width of the bag body 2, and the length is such that when the sheet 4 is unfolded outwardly, the sheet 4 comes out of the opening of the bag body 2. Has a length. The bonding surface 6 has a length slightly shorter than the lateral width of the bag body 2 and is provided over the entire width direction of the sheet 4. Further, the bonding surface 6 is a portion that is bonded to the inner surface of the bag body 2 adjacent to the inner side of the chuck 3, and can cover almost the entire chuck 3 with the sheet 4 when the sheet 4 is spread outward. it can.

  The knob 7 has a rectangular shape with a thickness of 1 mm or less and a side of about 1 cm, and one side thereof is bonded and fixed to the central portion of the surface opposite to the bonding surface of the sheet 4. The hinge portion 8 is of the same type as that used for a natto container or the like called a cover lid PSP container, and is provided adjacent to the adhesive surface 6. By folding the sheet 4 180 degrees around that axis, the sheet 4 can be easily deployed outside the opening of the bag body 2 and stored inside the bag body 2. The state of FIG. 1 is a state in which the sheet 4 is stored.

  The material of the sheet 4 is preferably strong enough to maintain a certain shape when deployed. For example, soft plastic.

  Next, the manufacturing method of the sealing bag 2 which concerns on this embodiment is demonstrated. First, the bag body 2 having the chuck 3 and the sheet 4 are individually manufactured. Then, the embodiment of the present invention is completed by adhering the adhesive surface 6 of the sheet 4 shown above to the inside of the chuck 3 of the bag body 2 by a method such as heat welding or adhesive.

  Then, the usage method of the sealing bag 2 which concerns on this embodiment is demonstrated. Here, it is assumed that the powder content is already contained in the bag body 2. As shown in FIG. 2, the user of the sealed bag 1 first opens the bag body 2, then grips the knob 7 attached to the sheet 4 with a finger, and opens the sheet 4 with the hinge portion 8 as an axis. Expand outside. Then, the sealing bag is moved so that the tip of the sheet 4 comes on a tray or the like from which the contents are to be taken out, and the sealing bag is tilted or simultaneously vibrated.

  Then, the contents are stably taken out along the guide 5 formed by the center of the sheet 4 being recessed. The guide 5 is formed to a depth suitable for use by opening the opening of the bag body 2 in an elliptical shape or a circular shape. And since the sheet | seat 4 is expand | deployed in the form which covers the chuck | zipper 1, a content does not adhere to the groove part of the chuck | zipper 1. FIG. Therefore, the function of the chuck 1 is not impaired and the hermeticity of the sealing bag is maintained. Further, the sheet 4 has such a size as to protrude outward from the opening of the bag body 2, and the contents can be prevented from adhering to the inner surface of the bag body 2 outside the chuck 3.

Although the present embodiment has been described in detail above, the embodiment of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention. For example, modifications of the present invention are shown below.
Modification 1 is shown in FIG. In Modification 1, the sheet 4 attached to one side of the sealing bag is attached to both sides. As a result, since both sheets 4 can be used, it is not necessary to confirm the orientation of the sealing bag at the time of use.

  Modification 2 is shown in FIG. In the second modification, the sheet 4 has a cylindrical shape, and the adhesive surface 6 is attached in a circular shape inside the sealing bag. Since the sheet 4 has a cylindrical shape, the content is wrapped in the sheet 4 until it comes out from the front end of the sheet 4. As a result, the contents can be taken out more stably. Moreover, the effect of the modification 1 is also obtained.

  The above-described invention is particularly effective when storing powdered foods such as kinako and cocoa.

It is a figure which shows the structure of the sealing bag of embodiment. It is an expanded view at the time of use of the sealing bag of embodiment. It is a figure which shows the modification 1 of this embodiment. It is a figure which shows the modification 2 of this embodiment.
