  Hereinafter, as an embodiment of the present invention, a packaging bag containing a membrane used to regenerate periodontal tissue and the like in the field of dental care will be described based on the drawings. In the drawings, the same components are denoted by the same reference numerals, and redundant description may be omitted.

  FIG. 1 is a perspective view of a packaging bag 100 according to an embodiment. FIG. 2 is a top view of the packaging bag 100 according to the embodiment.

  The packaging bag 100 is formed of a single rectangular film 10, and has a back attachment portion 20, a first seal portion 31, a second seal portion 32, an opening portion 40, and a storage portion 50.

  The film 10 is, for example, a laminated film in which a base material layer and a sealant layer are laminated.

  The base material layer is, for example, polyester film such as polyethylene terephthalate film, polyethylene naphthalate film, polyolefin film such as polypropylene, polystyrene film, polyamide film such as 6-nylon, polycarbonate film, polyacrylonitrile film, polyimide film, etc. .

  The sealant layer may be, for example, low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, ethylene-methacrylic acid copolymer (EMAA), ethylene-ethyl acrylate copolymer (EAA), ionomer And a polyolefin resin film such as polypropylene, which is laminated on the base material layer.

  In addition, an intermediate layer having a function such as gas barrier or light shielding may be formed between the base material layer and the sealant layer, if necessary.

  The film 10 is not limited to the materials and configurations described above as long as the film 200 can be stored in the storage unit 50 and sealed.

  Back sticking part 20 is formed in a state where side edges on the same side of the sealant layer side of film 10 abut, are heated and pressurized, and sealant layers heat-fuse. The film 10 made into a tubular shape by the back attachment part 20 is folded in a flat plate shape so that the back attachment part 20 is located in the vicinity of the side edge (upper side or lower side in FIG. 2). In addition, the spine portion 20 is folded back toward the side edge so as not to disturb the opening of the packaging bag 100.

  The first seal portion 31 and the second seal portion 32 are formed by heat and pressure being applied to heat seal the inner sealant layers while the film 10 is folded on a flat plate.

  The first seal portion 31 is formed at a position separated from the first open end 11 of the film 10 so as to form the unsealing portion 40, and seals one end (left side in FIG. 2) of the storage portion 50. In the first seal portion 31, both end portions 31a and 31c protrude toward the first open end 11 side with respect to the central portion 31b in the width direction (hereinafter simply referred to as "width direction") orthogonal to the extension direction of the back bonding portion 20 It is formed to be.

  Both end parts 31a and 31c of the 1st seal part 31 are formed out of the field of opening part 40 in the cross direction. Both ends 31a and 31c of the first seal portion 31 hold the both sides of the unsealing portion 40 at the time of unsealing the packaging bag 100 so that the unsealing portion 40 is scooped up to facilitate opening.

  The second seal portion 32 is provided on the second open end 12 side of the film 10, and seals the other end (right side in FIG. 2) of the storage portion 50.

  The unsealing portion 40 is provided on one side (upper side in FIGS. 1 and 2) of the film 10 opposed at the first open end 11. The unsealing portion 40 is formed by a pair of notches 41 and 42 which are separated in the width direction, and can be scooped up. The unsealing portion 40 is formed between both end portions 31 a and 31 c of the first seal portion 31 in the width direction.

  In addition, the notches 41 and 42 are formed in parallel to the extending direction of the spine attachment portion 20 along both end portions 31 a and 31 c of the first seal portion 31. The notches 41 and 42 may be, for example, notches cut in a V shape.

  In addition to the opening part 40 formed in the 1st opening end 11, the 2nd opening end 12 may be provided with the same opening part as the opening part 40. In this case, the second seal portion 32 is provided at a position separated from the second opening end 12 as in the case of the first seal portion 31. Moreover, it is preferable that the 2nd seal | sticker part 32 is formed so that the both ends outside the area | region of an opening part in the width direction may project on the 2nd open end 12 side rather than a center part.

  The storage portion 50 is a space which is covered by the film 10 and sealed by the spine portion 20, the first seal portion 31 and the second seal portion 32, and stores the membrane 200. In the storage unit 50, in a state where the membrane 200 is disposed in a region not overlapping with the spine attachment portion 20, the first seal portion 31 or the second seal portion 32 is formed while being pressurized and heated while being sucked. The membrane 200 is sealed. By suctioning at the time of sealing, the membrane 200 can be sandwiched and fixed between the films 10, and the membrane 200 can be prevented from being pinched by the first seal portion 31 or the second seal portion 32.

Here, in the packaging bag 100 according to the present embodiment, the spine attaching portion 20 is provided outside the region of the unsealing portion 40 in the width direction and near the side edge. Therefore, membrane 200 can be stored in storage portion 50 without arranging membrane 200 so as not to overlap with spine portion 20 and damaging membrane 200 with spine portion 20 when pressurizing and heating at the time of sealing. It has become. Further, at the time of storage of the packaging bag 100, the possibility of the membrane 200 being pressed by the spine portion 20 and being damaged is reduced.

  As described above, the packaging bag 100 is formed of a single rectangular film 10, and the membrane 200 is accommodated in the storage portion 50 sealed by the spine portion 20, the first seal portion 31, and the second seal portion 32. Store the Further, the packaging bag 100 is opened by cutting the film 10 from the opening portion 40, and the membrane 200 can be removed from the storage portion 50.

  FIG. 3 is a view illustrating a state in which the packaging bag 100 according to the embodiment is opened.

  As shown in FIG. 3, the unsealing portion 40 is gripped, the first seal portion 31 is peeled while tearing the film 10 from the notches 41 and 42, and the film 10 is further teared toward the second seal portion 32. The bag 100 can be opened.

  Here, the unsealing portion 40 is in a state in which both sides in the width direction are pressed by the both end portions 31 a and 31 c of the first seal portion 31. Therefore, the force applied to the film 10 when gripping and pulling the unsealing portion 40 is concentrated on the central portion 31 b of the first seal portion 31, and the first seal portion 31 can be easily peeled off.

  After the packaging bag 100 is opened from the opening section 40, for example, as shown in FIG. 4, the packaging bag 100 is held so that the opened portion is warped, and the upper side of the membrane 200 is separated from the film 10 Make it stand out. As described above, when the packaging bag 100 is held, the upper end of the membrane 200 is easily grasped and taken out with tweezers or the like.

  The packaging bag 100 which concerns on this embodiment is provided with the back sticking part 20 out of the area | region of the opening part 40 in the width direction. The back-sealed portion 20 is higher in rigidity and stronger in stiffness than the other portions because the film 10 is overlapped and fused. For this reason, if the spine-adhering portion 20 is provided at a position overlapping the unsealing portion 40, the unsealing portion 40 may be easily returned to the original position after unsealing, and the unsealing portion may be closed again to make it difficult to take out the membrane 200. .

  However, in the packaging bag 100 which concerns on this embodiment, since the spine attachment part 20 is provided out of the area | region of the opening part 40, the attitude | position of the film 10 containing the opening part 40 becomes easy to be maintained after opening. Therefore, as shown in FIG. 3 and FIG. 4, the unsealed state is maintained, and it becomes easy to take out the stored membrane 200. For example, while holding the packaging bag 100 with one hand, the other hand can remove the membrane 200 using tweezers or the like.

  Moreover, when the spine attachment part 20 and the opening part 40 are provided in the opposite side (For example, in FIG. 1, the back attachment part 20 is formed in the lower surface side, The opening part 40 is formed in the upper surface side etc.) )think of. Also in this case, if the spine portion 20 is provided at a position overlapping the opening portion 40, it becomes difficult to hold the packaging bag 100 with one hand so as to warp it as shown in FIG. It can be difficult. Therefore, even if the spine portion 20 and the unsealing portion 40 are formed on the opposite side, the spine portion 20 is preferably provided outside the region of the unsealing portion 40.

  As described above, according to the packaging bag 100 according to the present embodiment, the tearing of the film 10 from the incisions 41 and 42 by grasping the unsealing portion 40 can easily occur without damaging the contained membrane 200. It can be opened. Further, since the opened state is maintained and the membrane 200 can be deformed so as to be easily taken out, the membrane 200 can be easily taken out from the storage unit 50.

  As mentioned above, although the packaging bag which concerns on embodiment was demonstrated, this invention is not limited to the said embodiment, A various deformation | transformation and improvement are possible within the scope of the present invention.

  For example, an item other than the membrane 200 may be stored in the packaging bag 100 as long as it is used for dental treatment or the like. Moreover, the packaging bag 100 may be formed in the size according to the articles to be stored, and may be formed in the shape of a gusset bag in which the side end is folded in a hook shape. Furthermore, the widths of the spine attachment portion 20, the first seal portion 31, the second seal portion 32, and the unsealing portion 40, the lengths of the notches 41 and 42, etc. depend on the size of the packaging bag 100 and the articles to be stored. It is appropriately designed so that the storage unit 50 can be sealed and opened.
