Description

  The present invention relates to a lid label for a wet tissue package.

  In wet tissue packages in which a sheet impregnated with a chemical solution is laminated on a nonwoven fabric or paper and wrapped with a soft film made of synthetic resin, a pressure-sensitive adhesive is provided to prevent the sheet from drying out from the outlet. In general, the outlet is sealed with a flexible lid (such as a film made of a synthetic resin such as polypropylene or polyethylene). When the sheet is taken out, the lid is raised to open the outlet, but the lid returns to its original state due to repulsion, and the sheet may be difficult to take out or the pressure-sensitive adhesive may be in hand. there were.

  As a countermeasure against this, by forming a concave and convex cut at the boundary between the adhesive fixing part and the peelable part that is permanently fixed to the package so as to keep the cover open, it causes the cover to cut. There is a device in which the part is repelled by the bending of the lid member and acts as a support for maintaining the rising.

  However, for reasons such as shape and size, if the adhesive is present on the entire surface of the label, the function of the rising holding function may be hindered. It was necessary to attach a member, which was a factor in increasing costs. In addition, the opening / closing operation sometimes lacks smoothness.

  In wet tissue packaging, the sheet outlet of a wet tissue packaging that is laminated and packaged with a sheet impregnated with a chemical solution on a nonwoven fabric or paper is closed with a lid label with a pressure-sensitive adhesive on the back. Provides a lid label rise and stop mechanism that peels off the lid label that closes the sheet take-out port of the body, stops it at a predetermined position, and eliminates the lid label rise stop when the outlet is closed after taking out the sheet The purpose is to do.

  The present invention is provided with a pin tab at one end in the longitudinal direction of the lid label, and on the opposite side, a fixing area for stopping the peeling of the lid label at a predetermined position by making a cut from both opposite ends, It features a wet tissue using an adhesive lid label provided with a plurality of rising and holding mechanisms consisting of small pieces of open loops.

The ratio L / w between the length L of each piece and the maximum width w of the piece is 0.75 or more and 1.2 or less. If it is smaller than 0.75, the repulsive force of the small piece cannot be sufficiently exerted, and if it is larger than 1.2, it is difficult to reverse due to the bending of the lid label, and even if it is reversed, it is difficult to return to the original state. Further, the ratio (w ₁ + w ₂ ·· w _n ) / W (where n = 1, 2 or 3) with respect to the width W of the lid label is 0.45 or more, 0 The holding function and smooth operation are ensured by setting it to .60 or less.

The shape of the small piece may be asymmetrical with the tip displaced as well as symmetrical. The tip is linear or arcuate. Furthermore, you may make a cut | interruption in a front-end | tip part.
In addition to arranging the small pieces symmetrically with respect to the center in the longitudinal direction, the size and interval of the small pieces may be changed in consideration of the direction of force when peeling.

  In order to enhance the retention by the small pieces, the packaging material may be provided with a receiving portion (projection, recess, cut) of the holding mechanism.

By making the rising and holding mechanism of the lid label a small piece that defines the aspect ratio, even when pressure sensitive adhesive is present on the entire surface of the lid label, when the lid is opened, the small piece is easily peeled off from the package, From the repulsive force against the deflection of the lid label, it is possible to ensure the action as the rising holding mechanism. Also, when the label is closed, it returns to the original position smoothly.
Since there are a plurality of rising and holding mechanisms for the lid label, the rising and holding function is enhanced.
Between each small piece, the label base part used by repeating adhesion and peeling is reinforced and plays a role of assisting the action of the rising and holding function.
The holding performance is further improved by providing the receiving part of the rising holding mechanism on the soft film of the package.

  Examples of the present invention are shown below, but these are given for illustrative purposes and do not limit the present invention.

FIG. 1 shows a state in which the lid label of the wet tissue package is peeled off and stopped at a predetermined position. 1 is a packaging body, 2 is a tissue outlet, 3 is a lid label, 4 is a pressure-sensitive adhesive on the back surface, and 5 and 5 are left and right cuts for setting a fixed area for stopping the lid label 3 from being peeled off at a predetermined position. , 6 and 6 are small pieces of an open loop provided between the cuts 5 and 5.
Therefore, when the lid label 3 is opened to the front end of the fixed region set by the cuts 5 and 5, the two small pieces 6 and 6 are peeled off from the surface of the package to act as a support for rising the lid label. The pressure sensitive adhesive is present on the entire back surface of the lid label, and a cutout piece 7 at the outlet of the package body is adhered to the center.

  FIG. 2 exemplifies the details of the rising and holding mechanism of the lid label on the outlet of the package, and 8 is a tab. A is an example in which the tip portions of the small pieces 6 and 6 are flat, B is an example in which the tip portions of the small pieces 6 and 6 are convex outward, and C is an example in which the tip portions of the small pieces 6 and 6 are displaced. , D is an example provided with three small pieces 6, 6, 6.

  FIG. 3 shows the shape of the rising and holding mechanism. By setting 0.75 ≦ L / w ≦ 1.2, even if an adhesive is present on the back surface of the small pieces 6 and 6, peeling is easy, Smooth operation when opening and closing the lid label.

  FIG. 4 shows the shape of the small pieces 6 and 6 of the rising and holding mechanism. A is an example in which the tip of the small pieces 6 and 6 is displaced, B is an example in which a cut 9 is made in the tip, and C is the tip. This is an example in which the concave portion 10 is provided in the portion.

FIG. 5 shows a cross-sectional view of the rising and holding mechanism, and B is an example in which unevenness (embossing) is provided on the surface of the packaging body 1 (the portion in the vicinity of the fixed area) in order to enhance the rising and holding of the lid label 3 by the small piece 6. A is an example of a normal smooth surface.
FIG. 6 shows a conventional example, in which A is a lid label and B is a wet tissue package using the lid label.
