Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sealing sticker used for sealing a joint of a packaging sheet for packaging solid food such as rice balls.

[0002]

[Prior art]

 FIG. 5 shows a conventional sealing seal. The sealing seal 21 is formed by applying an adhesive 22 (see FIG. 7) to the back surface of the sealing material, and the adhesive 22 is arranged on the upper surface of the strip-shaped release paper 23 with a gap therebetween so that each sealing seal 21 A plurality of cuts 24 are made by pressing the blade mold on at least one side.

In order to attach the sealing sticker 21 to the joint 27 of the packaging sheet 26 for solid food such as rice balls, the sealing sticker 21 is arranged on the belt 31 on the outer periphery of the roller 30 as shown in FIG. The release paper 23 is moved along the release paper 23 by rotating the roller 30 in the direction of the arrow.

By the way, since the adhesive strength of the sealing seal 21 to the release paper 23 is weak, when the individual sealing seals 21 are transferred to the outer periphery of the roller 30, the sealing seals 21 are separated by the elasticity of the sealing material. While separating from the paper 23 and returning to a flat plate shape, this is sucked by the vacuum device 32 disposed in front of the roller 30, and the vacuum device 32 is moved in the feeding direction indicated by the arrow, as shown in FIG. As shown, it is attached to the seam 27 of the packaging sheet 26 for solid food such as rice balls.

Then, at the same time as opening the mating surface 28 on one side of the packaging sheet 26, the sealing seal 21 is torn along the notch 24 at the seam 27 to unseal.

[0006]

[Problems to be solved by the device]

 By the way, since the notch 24 formed in the sealing seal 21 is formed in a state of being connected to the edge of one side of the sealing seal 21, when the notch 24 is made by pressing the blade die as described above. As a result of the adhesive 22 of each cut 24 parts cutting into the release paper 23 at the edge of the seal seal 21, the cut 24 part of the seal seal 21 becomes difficult to separate from the release paper 23.

Therefore, as shown in FIG. 7, when the cut 24 is located at the front end in the transfer direction, the sealing seal 21 reaching the outer periphery of the roller 30 is separated from the release paper 23 at the cut 24 portion. However, there is an inconvenience that it is stuck to the release paper 23 and is caught around the outer periphery of the roller 30 as indicated by the chain double-dashed line 21 '.

Even when the notch 24 is located at the rear end in the transfer direction, the notch 24 at the rear end of the sealing seal 21 adheres to the release paper 23 and winds around the roller 30 without being separated, similarly to the above. Will be crowded.

The present invention has been made in view of the above circumstances, and can be easily separated from the release paper when passing through the roller of the automatic sticking device to be stuck by vacuum, and the seam of the packaging sheet can be opened. By doing so, the sealing sticker attached to this joint was torn at the same time.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the sealing seal of the present invention has an uncut portion having a minute width along the edge of at least one side of the sealing material provided with the adhesive layer, and along the inside thereof. When the packaging sheet is opened in a state in which the sealing material is attached to the joint of the packaging sheet, the seal material is easily attached to the notch located at the joint. It was made to be torn.

[0011]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a sealing seal of the present invention. FIG. 2 is a front view in which the sealing sticker of FIG. 1 is attached to the seam of the rice ball packaging sheet. FIG. 3 is a partial plan view showing a state in which the sealing seal of FIG. 1 is aligned with a strip-shaped release paper. FIG. 4 is a cross-sectional view of the sealing seal of FIG. 3 taken along the line AA.

FIG. 1 shows a sealing seal 1 for sealing the joint 3 of the packaging sheet 2 shown in FIG. 2, which has a minute width along at least one side edge of a sealing material having a predetermined shape which constitutes the sealing seal 1. It has an uncut portion 5 of t, and a plurality of cuts 6 are provided along the inner side of the uncut portion 5.

The plurality of cuts 6 press a blade die (not shown) in which a plurality of projecting blades are arranged at a position where a margin (uncut portion 5) is left at the edge of at least one side of the sealing seal 1. It is formed by doing so that, as a result, the notch 6 is not connected to the edge of the sealing seal 1.

As shown in FIG. 2, such a sealing sticker 1 is attached to the seam 3 of the packaging sheet 2 for solid food such as rice balls, as in the conventional case, and the seam 3 is sealed. It can be carried out.

When the packaging sheet 2 is opened, the sealing surface 1 on one side is pulled up by the seam 3 so that the sealing seal 1 can be easily installed along the notch 6 at the same position as the seam 3. It can be torn.

When the mating surface 7 on one side is pulled up at the time of unsealing, it is the uncut portion 5 of the sealing seal 1 that first comes into contact with the unsealed portion 5 as described above. Since the width t is very small and easily cut, the cut 6 immediately follows the seam 3, and the sealing seal 1 is cut along the cut 6.

Further, FIG. 3 shows the above-mentioned sealing seal 1 aligned on a strip-shaped release paper 8, and a sealing material is attached to the upper surface of the release paper 8 with an adhesive layer 9 at predetermined intervals. Then, necessary printing (printing layer 10) is applied to the upper surface of each sealing sticker 1.

In the present invention, when a device similar to that shown in FIG. 7 is used to separate the sealing sticker 1 continuously attached to the release paper 8 from the release paper 8, the release paper 8 is fed. The original elastic force of the sealing material acts on the uncut portion 5 arranged at the tip in the direction, and this portion can be separated from the release paper 8.

Then, the residual force of this elastic force also acts on the portion of the notch 6, so that the portion where the notch 6 and the release paper 8 adhere is separated, and the sealing seal 1 is warped from the outer periphery of the roller 30. It becomes possible to transfer it to the vacuum device 32 side by transferring it flatly.

In the above embodiment, the uncut portion 5 and the notch 6 are formed on only one side of the sealing seal 1, but they may be provided on the other side and all sides.

[0022]

[Effect of the invention]

 As described above, the sealing seal of the present invention has the uncut portion having a minute width along at least one edge of the sealing material provided with the adhesive layer, and has a plurality of uncut portions along its inner side. Since the notch is provided so that the notch does not lead to the edge of the sealing seal, there is no notch at this edge and it adheres to the release paper with a slight adhesive force.

Therefore, when the sealing seals are arranged on the strip-shaped release paper so as to be transported on the outer periphery of the roller, when the individual sealing seals reach the outer periphery of the roller, the edge having the uncut portion is formed. The end portion is easily peeled off from the release paper and is transferred to the vacuum device side in a flat state, so that the winding of the roller in the outer peripheral direction unlike the conventional case does not occur.

Since the sealing seal of the present invention is provided with a plurality of cuts along the inner side of the uncut portion, the sealing seal is attached to the seam of the packaging sheet. When the packaging sheet is opened by opening the sealing sheet, the sealing seal can be easily torn at the notch located at the seam, which is similar to the conventional effect.
