Abstract

PROBLEM TO BE SOLVED: To solve the problems that opening of a zippered packaging bag with a heat-adhesive part is conventionally difficult due to that the heat-adhesive part is cut off and both front and rear of a cut area are cut at the same height so as to make hooking with the finger difficult.SOLUTION: Opening is facilitated by adhering a non-cut area to the rear of a zippered bag so as to lead a cutline when cutting off with the hand from a notch part, and make a handle alternate in the front and rear.SELECTED DRAWING: Figure 1

Description

  The present invention relates to opening a bag with a zipper.

As shown in FIG. 2, the cutting line used for the conventional bag with a zipper is provided with cuts on either the left or right side or both the left and right sides as shown in FIG. It is made to separate with.
As shown in FIG. 2, a bag with a zipper is assumed, which has a thermal bonding portion at the top, a zipper portion on the contents, and a notch between the thermal bonding portion and the zipper portion. As shown in FIG. 3, after cutting off the heat-bonding portion, the front side 1 and the inner side 2 of the front side A of the bag, and the front side 3 and the inner side 4 of the back side B surface are cut on one side for tearing by hand. Two types are assumed: one type and the left and right sides. FIG. 2 is a front view of FIG. 3 with a thermal bonding portion attached.

  JP-A-2005-231732 (P2005-231732A)   Utility Model Registration No. 3167770 (U3167770)   Utility Model Registration No. 3160309 (U3160309)   JP-A-2004-231290 (P2004-231290A)

  However, according to the above technique, even if [Patent Document 1] is unopened, if the tag is pulled from both sides due to mischief or a store operation mistake, the contents will flow out beyond the zipper. In [Patent Document 2], when a perforation is made in the dotted line portion, the thermal bonding portion at the top of the knob cannot be cut by hand, and scissors or the like must be used, or a shallow slit is made on the surface of the bag with a zipper However, when the contents are food, there are concerns about quality, [Patent Document 3] means that multiple tears are required when cutting by hand along the perforation, [Patent Document 4] In the first place, it shows that thermal bonding is insufficient, and this thermal bonding is intended to maintain the quality of the product by blocking the contents from the outside air, and should not be easily peeled off by hand. is there. Accordingly, an object of the present invention is to make it possible to easily open and close the zipper part after the bag with the zipper is torn once without using a tool.

  In order to solve the above-described problems, the present invention provides a handle for opening and closing a zipper portion by inducing a cut line by tearing a bag with a zipper once to generate two alternate cut lines having irregularities on the bag. It is a bag with a zipper characterized by the part being cut into irregularities.

  According to the invention of the present application, since there is no tag as in [Patent Document 1], it is not accidentally opened, and since there is no perforation as in [Patent Document 2], the quality of the contents is affected. Since there is no application, there is no need for multiple tears as in [Patent Document 3], and there is no risk of quality degradation due to insufficient adhesion of the thermal bonding portion as in [Patent Document 4]. Since the handle of the attached bag is cut into alternate uneven shapes, even those who are not dexterous can easily open and close it.

It is a representative drawing which shows "this invention" embodiment. It is a "prior art" perspective view and shows a state where a thermal bonding portion is still attached. (One notch on the right) It is the figure which cut off the heat bonding part of the "prior art" bag with a zipper, and showed the front side and back side of the bag, and the inside. [Invention of this application] It is the figure which produced | generated the non-cut part inside the bag with a zipper. [Invention of this application] It is the figure which unfolded up and down the bag with a zipper which produced the non-cut part. [Invention of this application] It is the figure which unfolded up and down the presumed cut line when the bag with a zipper was cut out by hand from the cut. “Invention of the present application” is a cut line when a bag with a zipper is actually cut from a cut by hand, and is a state after tearing. “Invention of the present application” is a variation of a non-cut portion. [Prior Art] It is a perspective view with two notches on the left and right. [Prior Art] FIG. 7 is a front view with two thermal cutting portions and left and right thermal bonding portions. [Invention of this application] It is the figure which produced | generated the non-cut part inside the bag with a zipper in the case where a cut part is two places right and left. [Invention of this application] It is the figure which unfolded the bag with a zipper which produced the non-cut part in the case where the cut part is two places on the right and left. “Invention of the present application” is a presumed cut line when the zippered bag is cut by hand from the right cut in the case where the cut portions are two left and right. "Invention of the present application" is a cut line when the zippered bag is actually cut by hand from the right cut. [Invention of the present application] When there are two left and right cuts, this is a cut line when the zippered bag is manually cut from the left cut. “Invention of the present application” is a cut line when the zippered bag is actually cut by hand from the left cut.

After opening the conventional zippered bag with a sealed zipper (there is a heat bonding part at the top), the cut line from the cut will be the same on the front and back, so when opening and closing the zipper part, it will be delicately pulled apart The elderly with bad eyes and those whose fingertips were not dexterous could hardly be opened. In order to solve the above, an embodiment of the present invention is shown in FIG. It is an idea that can be easily opened by cutting the A side: the cut line 5 on the front side 1 and the B side: the cut line 6 on the inside 2 as shown in the representative drawing.
FIG. 4 shows the non-cut portions 7, 8, 9, and 10 attached to the inner side 2 of the A surface and the inner side 4 of the B surface with resin, solid matter, and scissors at the time of manufacturing the zippered bag.
Since this non-cut portion is resistant to the cut, even if it is cut from the cut portion by hand, the straight line of the cut line is prevented by this non-cut portion.
The term "non-cut part" as used herein refers to any material that is artificially formed into a useful shape using a polymer material typified by plastic as the main raw material, or that includes natural, synthetic, or rubber, paint, and adhesives. Apart from this, the same function can also be given by processing the bag on the zippered bag itself or by fixing a resin or rubber wire to the zippered bag with an adhesive. Alternatively, a material that cannot be cut is embedded in the zippered bag itself.
Fig. 5 shows a zippered bag developed up and down, with two non-cut parts 7 and 8 on the inner side 2 of the A surface and two non-cut parts 9 and 10 on the inner side 4 of the B surface. Let
The non-cut portion may be on the surface, but the insides 2 and 4 are appropriate because the printing and appearance of the zippered bag deteriorates.
Further, if different colors are used for the zippered bags on the front side 1 and 3 and the inner side 2 and 4, it is easy to determine that the front and back sides are staggered.
FIG. 6 is an expected development view of a cut line when the A-side inner side 2 is pulled leftward from the cut (right) 11 by hand to separate the upper portion of the zippered bag. If you tear the upper part of the bag with zipper by hand from the notch (right) 11 to the left, you can not go straight to the left at the non-cut part 7 in FIG. Since the line advances and this time it becomes impossible to go straight to the left at the non-cut portion 8, the cut line advances by changing the direction upward. After that, it is coasting and cut off to the left end. On the other hand, the cut line on the B-side inner side 4 advances in the left direction simultaneously with the cut (right) 11 on the A-side inner side 2, and at the non-cut portion 9, the cut line cannot move straight to the left. The cut line 14 advances so as to sink into the lower part, and then cannot move straight to the left as it is at the non-cut part 10, so the direction is changed to the upper direction and the cut line 15 is advanced. After that, it is coasting and cut off to the left end. Finally, it is cut as shown in “Representative Drawing” in FIG. 1, and can be easily opened by pinching the zippered bag with the fingers of both hands.
FIG. 7 shows the actual cut lines 5 and 6 of the present invention.
FIG. 8 shows variations of the non-cut portions 7, 8, 9, and 10 that are artificially formed into a useful shape using a polymer material represented by plastic as a main raw material, or natural, synthetic, or All string-like solids including rubber, paint, and adhesive are attached. Alternatively, a bag is generated in the zippered bag during the production process, and the function of preventing straight advancement of the cut line at the time of tearing is provided. FIG. 9 shows an example in which the cut (right) 11 and the cut (left) 22 are provided on the left and right. It is.
FIG. 10 is a view of FIG. 9 as seen from the front side with the heat-bonded portion cut away.
FIG. 11 shows the case in which the non-cut portions are attached to the inner side 2 of the A surface and the inner side 4 of the B surface with a resin, a solid material, and a scissors at the time of manufacturing the bag with the zipper when the slits are on the left and right.
FIG. 12 shows the zippered bag shown in FIG. 11 developed vertically, with two non-cut portions 7 and 8 on the inner side 2 of the A surface and two non-cut portions 16 and 17 on the inner side 4 of the B surface. To generate.
As shown in FIG. 11, FIG. 13 has cut portions on both the left and right sides, and the inside of the A surface is the A surface when the upper portion of the bag with a tearing zipper is separated from the cut (right) 11 by hand. It is the anticipation expansion | deployment figure of the cut line 18 of this, and the cut line 19 of B surface.
FIG. 14 shows an A-side cut line 18 and a B-side cut line 19 that are actually cut from the right notch, as shown in FIG.
FIG. 15 is an expected development view of a cut line when there are cut portions on both the left and right sides, and the A-side inner side 2 is pulled from the cut (left) 22 to the right by hand to separate the upper portion of the bag with zipper. .
FIG. 16 shows the A-side cut line 20 and the B-side cut line 21 actually cut from the cut (left) 22 with cuts on both the left and right sides, as shown in FIG. 15.
Although there is a difference in the cut line depending on whether the cut portion is only on the left or right side, on both the left and right sides, or on the left and right sides, the ease of opening the zippered bag is not impaired.

"Effect of the embodiment"
According to this embodiment, since the handle of the zippered bag is alternately cut regardless of who uses the tool, the subsequent opening operation is simplified.
"Other embodiments"
As shown in the embodiment of FIG. 14, the cut lines on the A side and the B side are different in the case where the cut opening is located on both the right and left sides, but the ease of opening the bag with the zipper is different. Not damaged. There is an advantage that the user does not hesitate because the slits are on the left and right.
