(First embodiment)
Below, the preferred embodiment is described with reference to an accompanying drawing about the package with a resealable zipper concerning the present invention.
FIG. 1 illustrates an embodiment of a package with a resealable chuck according to claim 1 of the present invention. The packaging body 11a with a resealable chuck has a front surface member 12a and a back surface member 12b sealed in a bag shape by well-known means. The packaging body 11a with a resealing chuck has side seals 13a and 13b on both sides and an upper part. The upper seal 14a and the lower seal 14b are provided at the lower portion, and the resealing chuck 15 is provided over the side seals 13a and 13b below the upper seal 14a at the upper portion of the package 11a with the resealing chuck.

  The film of the package is a composite film, and a heat-weldable plastic film may be used with its welding surface inside, and the outer layer or intermediate layer is a paper layer or an aluminum layer. Also good.

  A notch 17 is formed at the same position in the central portion of the outer edge of the upper seal 14a of the front member 12a and the back member 12b, and the vertical sewing machine extends at least downward from the position corresponding to the notch 17 in the front member 12a and the back member 12b. The perforations 19a and 19b in the transverse direction are formed on the front side film and the back side film of the unsealed portion below the upper seal and above the resealing chuck. , 18b so as to cross the end. The lateral perforations 19a and 19b are formed to extend in the opposite direction to the opposite film. In the embodiment, the notch 15 is a V notch, but is not limited to this, and may be an I notch. Further, although the vertical perforations 18a and 18b of the embodiment are formed at substantially the same position in the vertical direction, the vertical perforations 18a and 18b inclined in the same direction may be used, or the opposite side Longitudinal perforations 18a and 18b inclined in the opposite direction to the film may be used.

  In the method of opening the package 11a with the zipper for resealing according to the first aspect, first, the notch 17 is broken along the perforations 18a and 18b in the vertical direction. When the breakage progresses to the end points of the vertical perforations 18a, 18b and the crossing portions with the horizontal perforations 19a, 19b, the breakage progresses along the horizontal perforations 19a, 19b. Here, the lateral perforations 19a, 19b are formed so as to extend in the opposite direction to the opposite film, so that the breaks proceed along the lateral perforations 19a formed in the surface member 12a, The breaks that proceed along the lateral perforations 19b formed in the back member 12b proceed in opposite directions. If the rupture progresses and a sufficient opening is obtained, the contents can be taken out from the package. After opening, the upper seal 14a is divided into left and right, and functions as knobs 20a and 20b when the resealing chuck 15 is disengaged and the bag mouth is opened. The portion removed at the time of opening in the conventional package with a resealing chuck becomes the knobs 20a and 20b in the package of the present invention. The bag mouth can be opened.

  Since the vertical perforations 18a and 18b and the horizontal perforations 19a and 19b do not penetrate, the package is kept sealed.

  The horizontal perforations 19a, 19b are not formed beyond the vertical perforations 18a, 18b. In this case, when the bag mouth is opened by releasing the bite of the opening and resealing chuck, a lateral force acts on the knobs 20a and 20b. When the horizontal perforations 19a and 19b are formed beyond the vertical perforations 18a and 18b, the lateral direction is based on the ends of the horizontal perforations 19a and 19b beyond the vertical perforations 18a and 18b. This is to prevent the knobs 20a and 20b from being cut due to breakage.

  The horizontal perforations 19a may be formed up to the side seal 13a, and the horizontal perforations 19b may be formed until the side seal 13b is reached. When it is bent and broken at the time of opening, the problem that the knobs 20a and 20b are cut can be prevented.

  Further, using the film having the tearability in the lateral direction instead of forming the lateral perforations 19a and 19b up to the side seals 13a and 13b, the knobs 20a and 20b are cut at the time of opening. The problem can be solved.

  The horizontal perforations 19a and 19b are preferably provided in the immediate vicinity of the top of the reseal chuck 15. When the package is opened, it tears in the vertical direction, and when the rupture progresses to the resealing chuck 15, the rupture stops at the resealing chuck 15, and then the lateral rupture occurs along the lateral perforations 19a and 19b. It can be started and the lateral tearing can be performed smoothly. When the horizontal perforations 19a and 19b and the resealing chuck 15 are formed to some extent (for example, about 10 mm) apart, the transition from the vertical tear to the horizontal tear cannot be made smoothly. The problem of not being able to tear laterally can occur.

  Further, it is preferable that the ends of the perforations in the vertical direction and the ends of the perforations in the horizontal direction are connected by a curve instead of being connected at a right angle. It is possible to prevent the knobs 20a and 20b from being cut due to stress concentration at the corners of the bases of the knobs 20a and 20b when the re-sealing chuck is disengaged and the bag mouth is opened. .

(Second Embodiment)
FIG. 3 illustrates an embodiment of a packaging body 11b with a resealable chuck according to claim 2. The package 11b with a resealable zipper according to claim 2 has a tearable property in the longitudinal direction instead of forming the perforations 18a, 18b in the longitudinal direction on the front film and the back film of the package according to claim 1. A certain uniaxially stretchable film is used, and the unsealed portion 16 above the resealing chuck 15 with the front side film of the package and the lateral perforations 19a, 19b on the back side from the position on the vertical line of the notch. The lateral perforations 19a and 19b are formed so that the opposite film extends in the opposite direction b.

  When the package 11b with the zipper for resealing according to claim 2 is opened from the notch 17, since the uniaxially stretchable film having tearing property in the longitudinal direction is used, the longitudinal perforations 18a and 18b are not present. Also, the film can be linearly broken in the vertical direction, and the breaking of the perforations 19a and 19b in the lateral direction is started on the vertical line.
