  If the typical structure of the lid | cover material 3 is illustrated, PET film (base material layer) / aluminum foil (barrier layer) / uniaxially stretched film (base material layer, easy tear property) / polypropylene film (thermoplastic resin layer) Can be mentioned. Examples of the uniaxially stretched film include Trefan BOYT12, Trefan BOYT22 (trade name, manufactured by Toray Industries, Inc.), Kalarian Y (trade name, manufactured by Denki Kagaku Kogyo Co., Ltd.), Hybron, Noblen (trade name, manufactured by Mitsui Chemicals), Uni Aston (trade name, manufactured by Idemitsu Petrochemical Co., Ltd.).

  Next, a method for opening a packaging container and a method for taking out contents will be described. When taking out the content 8 for any one of the accommodating portions 4a to 4d, the container body 2 and the lid member 3 are broken along the first perforations 7a and 7b and the second perforations 10a and 10b. Thus, as shown in FIG. 4, one of the accommodating portions 4a to 4d (here, the accommodating portion 4a) is separated.

  The lid 3 is broken from the opening notch 11a in the MD direction of the film by gripping and lifting the knob 12a, and a slit-shaped opening hole 17 is formed in the accommodating portion 4a. By turning the formed opening hole 17 downward, the powdery content 8 filled in the accommodating portion 4 a slides down along the inclined portion 15 and falls from the opening hole 17.

  In addition, when the content 8 is a gel form or a semi-solid form, although depending on the viscosity of the content 8, the content 8 does not fall easily only by making the opening hole 17 face down. Therefore, by forming the container body 2 with a material that can be easily deformed by pressing with a finger, as shown in FIG. 5, the container 3 is accommodated by picking and pressing the lid 3 side and the accommodating portion 4a side with fingers. The portion 4 a is crushed, and the contents 8 filled in the housing portion 4 a can be easily squeezed out from the opening hole 17.

  Moreover, when taking out the content 8 for any two of the accommodating portions 4a to 4d, by breaking the container body 2 and the lid material 3 along the first perforation 7a and the second perforation 10a, As illustrated in FIG. 6, two of the accommodating portions 4 a to 4 d (here, the accommodating portions 4 a and 4 b) are separated. Then, by grasping and pulling up the knob portion 12a, the lid member 3 is broken in the MD direction of the film from the opening notches 11a and 11b, and slit-like opening holes 17 are formed in the housing portions 4a and 4b.

  As shown in FIG. 7, the powdered contents filled in the accommodating portions 4 a and 4 b are formed by turning the formed opening hole 17 downward and bending the ridge portion 6 b into a mountain shape along the first perforation 7 b. 8 slides down along the back surface of the lid 3 and falls from the opening hole 17. At this time, since the inclined portions 15 are formed in the accommodating portions 4a and 4b, the ridge portion 6b can be easily bent. In addition, the bent state can be reliably maintained by bringing the inclined portions 15 of the housing portions 4a and 4b into contact with each other.

  When the contents 8 are gel or semi-solid, the container body 2 is made of a material that can be easily deformed by pressing with a finger, so that the accommodating portions 4a and 4b are brought into contact with each other from the state shown in FIG. By further pressing, the accommodating portions 4a and 4b are crushed as shown in FIG. 8, and the contents 8 filled in the accommodating portions 4a and 4b can be easily squeezed out from the opening hole 17. At this time, since the inclined portion 15 formed in the accommodating portions 4a and 4b is formed in a curved surface that is convex outward, it is easily deformed by pressing, and the gel-like or semi-solid content 8 is accommodated. Since it becomes difficult to adhere to the inner corners of the portions 4a and 4b, the take-out property is improved.

  Further, when all four contents 8 of the accommodating portions 4a to 4d are taken out, the knob portion 12a (or the knob portion 12b) is gripped without separating the accommodating portions 4a to 4d as shown in FIG. Then, the lid 3 is broken in the MD direction of the film from the notches 11a and 11b for opening, and slit-like opening holes 17 are formed in the housing portions 4a to 4d.

  When the contents 8 are powder, as in FIG. 7, the formed opening hole 17 faces downward, and the ridge portion 6b is bent into a mountain shape along the first perforation 7b, so that the accommodating portions 4a to 4d are formed. The filled powdery content 8 slides down along the back surface of the lid 3 and falls from the opening hole 17. When the contents 8 are gel or semi-solid, the container body 2 is formed of a material that can be easily deformed by pressing with a finger, and the accommodating portions 4a and 4d and the accommodating portions 4b and 4c are connected to each other. By contacting and further pressing, the accommodating portions 4a to 4d are crushed and the contents 8 filled in the accommodating portions 4a to 4d can be easily squeezed out from the opening hole 17, as in FIG.

  As described above, the packaging container 1 of the present invention has the slit-shaped opening 17 formed in the accommodating portions 4a to 4d, so that the powdery material accommodated in the accommodating portions 4a to 4d when the contents are taken out, The gel-like and semi-solid contents 8 are not easily scattered. Therefore, two or four can be taken out at a time without polluting the operator's fingers. Further, by forming the container body 2 from a material that can be deformed by pressing with a finger, the gel-like and semi-solid contents 8 can be easily squeezed out.

  Further, since the knobs 12a and 12b are formed between the pair of opening notches 11a and 11b and 11c and 11d, for example, the accommodating parts 4a and 4b are separated, and the knob 12a is gripped. Even when the container is opened, a knob 12b for opening the remaining accommodating parts 4c and 4d is secured.

  In this case, the opening notches 11a to 11d are provided as the opening start means, but instead of the opening notches 11a to 11d, a scar group including a plurality of fine piercing holes on the outer periphery of the lid member 3 as the opening start means. It is also possible to provide a half cut that surrounds the region and the scar group region and tapers in the opening direction.

  Moreover, it can replace with the notches 11a-11d for opening, and can also form the half cut line extended along the both sides of the 2nd perforation 10a, 10b on the surface of the cover material 3 as an opening start means. In this case, it is necessary to form a half cut line so as not to impair the sealing performance of the lid member 3.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the shape of the container body 2 is not particularly limited, and may be polygonal as long as it has a flange portion and a ridge portion. Moreover, although the container main body 2 which has four accommodating parts 4a-4d was mentioned as an example and demonstrated here, if the notch for opening is formed along at least 1 ridge part adjacent to each accommodating part, 2 The container main body 2 having one or three accommodating parts may be used, or the container main body 2 having five or more accommodating parts may be used.

  Moreover, in the said embodiment, in order to isolate | separate each accommodating part 4a-4d, although the 1st perforation 7a, 7b was formed in the container main body 2, and the 2nd perforation 10a, 10b was formed in the cover material 3, If the accommodating portions 4a to 4d can be separated, a half cut may be formed instead of the perforation.

  INDUSTRIAL APPLICATION This invention can be utilized for the packaging container which sealed the resin-made container main body with the film-like cover material, and it extends along the ridge part which partitions a some accommodating part to a container main body, and reaches the outer periphery of a flange part.
