Description

  The present invention relates to an easy-open flap-wrapping easy-to-open packaging bag that uses a part of the flap as a tear pick piece. The present invention relates to a bag-free easy-open packaging bag with a flap made of a soft packaging film that is used for packaging in the case of sale.

  In general, products such as stockings described above use plastic films to form flexible packaging bags, store the contents, and then close the flaps using a pressure-sensitive adhesive tape that has been cut short. The packaging method was closed and displayed at the store. In addition, the purchaser of the above product can tear a part of the packaging bag with his / her finger using a so-called V-notch or a notch called I-notch that is cut in advance on the outer edge of the packaging bag. The contents were taken out from the packaging bag by opening, opening by peeling off the adhesive tape, or opening using a bag or a cutter (see Patent Documents 1 and 2).

However, when a cut portion such as a V-notch or an I-notch is provided at the outer edge portion of the flexible packaging bag, there is a problem that other packaging is damaged in the distribution process. Further, the method of peeling off the adhesive tape has a problem that the operation of peeling off the adhesive tape is not always easy and may be difficult. Moreover, the method of opening using a scissors, a cutter, or the like has a problem that the contents are cut unexpectedly as well as being troublesome to prepare a scissors, a cutter knife, etc.

  In addition, although the applicant of the present application has investigated the prior art specializing in “a part of the flap to be used as a tear tab and an easy-open packaging bag with a flap”, it is possible to find related prior art documents. could not.

  An object of the present invention is to provide a novel easy-open packaging bag with a flap that solves the above-mentioned problems.

  In order to achieve the above object, an easily openable packaging bag with a flap according to claim 1 is provided with a pressure-sensitive adhesive layer on the inner surface of the front edge, and the pressure-sensitive adhesive on the outer surface of the opening edge of the rear plate. A flexible packaging film packaging bag with a flap that can be closed by bonding using a layer, and an opening tape is bonded to the inner surface of the base edge of the flap along the base edge In addition, a ring-shaped line is virtually assumed at the end portion of the bonding portion of the opening tape, the opening tape and the flap are cut at the outer side portion of the virtual ring-shaped line, and the inner side portion of the virtual ring-shaped line is cut. Then, the opening tape and the flap are not cut, and the upper and lower sides of the virtual ring-shaped line are cut to form a discontinuous ring-shaped cutting line in which both ends are not continuous. On the cutting line Characterized in that manner has be used as a knob portion for tearing the enclosed portion Ri.

  Therefore, for example, when products such as stockings are packaged, the flaps may be preliminarily folded and stored, and then the flaps may be bonded to the outer surface of the opening edge of the rear plate using a pressure-sensitive adhesive layer. In addition, it is desirable that the product is folded neatly using a mount. In the case of taking out, it can be taken out without using a scissors or the like simply by pulling a tear tab provided on a part of the flap and cutting the flap to make it open. In addition, the ring-shaped cut line that forms the portion that functions as the tearing knob does not reach the outer edge of the packaging bag, so a V-notch, I-notch, or other incision that reaches the conventional outer edge is provided. Unlike other cases, other packaging bags are not damaged in the distribution process. Moreover, it can be easily opened without using a bag or a cutter.

  Moreover, the easy-open packaging bag with a flap according to claim 2 is the easy-open packaging bag with a flap according to claim 1, wherein the discontinuous ring-shaped cut line is formed on the rear plate when the flap is closed. It is characterized in that it is provided at a location where it is located outside.

  Therefore, at the time of display or the like, the rear plate exists inside the discontinuous ring-shaped cut line and closes the cut line of the same line, so that intrusion of dust or the like can be prevented.

  Since the easy-open packaging bag with a flap according to the present invention is configured as described above, it can be easily opened. In addition, problems such as damaging other packages at the notch such as V-notch and I-notch can be solved. Moreover, the trouble of preparing a ridge or a cutter can solve the problem of cutting the contents carelessly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which the whole is viewed from the rear side with the flap opened, FIG. 2 is a cross-sectional view taken along line 1A-A in a state where the flap is closed, and FIG. It is an expansion explanatory view showing details of a knob part for tearing.

  The easy-open packaging bag 1 with a flap according to this embodiment welds the left and right side edges and the lower side edge of the transparent front plate 2 made of biaxially oriented polypropylene film of 40 microns and the transparent rear plate 3 made of the same. By extending the flap 5 integrally with the opening of the front plate 2, the wrinkleless packaging bag body 4 with the flap 5 is configured.

  Further, a pressure-sensitive adhesive layer 6 is applied to the inner surface side of the front edge portion of the flap 5 in a state along the front edge portion, and a covering protective piece 7 is detachably attached to the applied surface. .

  The pressure-sensitive adhesive layer 6 is configured such that the packaging bag body 4 can be closed when the covering protective piece 7 is peeled off and the flap 5 is adhered to the outer surface of the opening edge of the rear plate 4.

  Further, a white 40-micron biaxially stretched polypropylene film opening tape 8 is bonded to the inner surface side of the base end edge of the flap 5 in a state along the base end edge. In other words, the thickness of the bonded portion is 80 microns so that the flap 5 is not cut even by pulling the tearing knob portion 11 described later.

  Further, a ring-shaped wire 9 having a diameter larger than the width of the opening tape 8 is virtually assumed at the opposite end portion of the bonding portion of the opening tape 8, and the outer side portion 9a of the virtual ring-shaped wire 9 is assumed. The cutting tape 8 and the flap 5 are cut, and the opening tape 8 and the flap 5 are not cut at the inner side portion 9b of the virtual ring-shaped line 9, and the upper side portion 9c and the lower side of the virtual ring-shaped line 9 are cut. At the location 9d, the above-described flap 5 is cut to provide a discontinuous ring-shaped cut line 10 whose both ends are not continuous, and a portion surrounded by the discontinuous ring-shaped cut line 10 is used as a tearing knob portion 11. It is something that can be obtained. Note that the virtual ring-shaped line 9 and the discontinuous ring-shaped cut line 10 appear to overlap and become unclear in the illustrated case, and therefore the virtual ring-shaped line 9 is slightly outside in FIG. The position is shifted and represented by a one-dot chain line.

  Therefore, when packaging the product 12 such as stockings using the easily openable packaging bag 1 with the flap according to the above embodiment, for example, the product 12 such as stockings is folded in advance into a thin and small state, and the packaging bag body 4 After being stored inside, if the flap 5 is bonded to the outer surface of the opening edge 3a of the rear plate 3 by using the pressure sensitive adhesive layer 6 which is exposed by removing the covering protective piece 7 immediately before. Well, the above-mentioned products 12 such as stockings can be taken out without using a bag etc. simply by pulling the tearing knob 11 provided on a part of the flap 5 and tearing the flap 5 to make it open. Can do.

It is a perspective view shown in the state which looked at the whole from the back side. FIG. 2 is a cross-sectional view taken along the line 1A-A in FIG. 1A with the flap closed. It is an expansion explanatory view showing details of a knob part for tearing.
