<First Embodiment>
FIG. 1 is a perspective view showing a packaging bag 1 or a package 100 according to the first embodiment of the present invention. The packaging bag 1 generally has a bottom surface portion and a side surface portion, and includes a trunk portion 3 on which a large number of hygiene articles as articles can be accumulated, a top surface portion 5 that is a substantial part covering the top surface, and a periphery thereof. A top portion 4 including a rising portion 6 that rises. These parts are not integrated after being manufactured separately, but can be integrally formed in advance by bending one sheet-like member, and at least in terms of appearance, A clear boundary does not appear between the part 3 and the top part 4. As shown in FIG. 1, the packaging body 100 of the present embodiment has a substantially rectangular parallelepiped shape in a state where a plurality of sanitary articles 2 are accommodated. That is, the bottom surface portion of the body portion 3 and the top surface portion 5 of the top portion 4 form a substantially rectangular shape facing each other in parallel.

  In the vicinity of the center of the top surface portion 5 of the top portion 4, for example, a perforation-shaped opening line 7 extending in parallel with the long side of the substantially rectangular shape is provided, and the opening of the packaging bag 1 is opened by breaking this. It is formed. In the present embodiment, the packaging body 100 is provided with a gap between the top surface portion 5 and the sanitary product to be accommodated, whereby both sides of the opening line 7 provided on the top surface portion of the top portion are pulled away from each other and broken. A grip allowance that facilitates operation is formed. When the slit-shaped opening is formed by breaking the opening line 7, the user can take out the necessary number of sanitary goods through the opening.

  The rising portion 6 of the top portion 4 is provided with a chuck portion 8 in the form of a plastic bite as an opening / closing portion that can open / close the inside of the packaging bag 1. The chuck portion 8 is provided in the circumferential direction of the inner side surface 6i facing the space on the top surface portion 5 surrounded by the rising portion 6, and as a pair of engaging portions engageable with each other, It has female elements 8a and 8b. The chuck portion 8 is used after the opening line 7 is broken and the packaging bag 1 is opened, and the packaging bag 1 can be opened and closed by engaging / disengaging the elements 8a and 8b. In the present embodiment, the chuck portion 8 is provided in the vicinity of the upper edge of the rising portion 6.

  On the other hand, on the outer side surface 6o on the opposite side to the inner side surface 6i of the rising portion 6, a handle 15 considering portability is attached to the side surface portions 6a and 6b connected to the pair of opposed long sides of the substantially rectangular shape. . In this embodiment, each handle 15 is, for example, a flexible resinous belt-like member, and both end portions thereof are well-known such as a welding method by heating or adhesion by applying an adhesive to the outer surface 6o. It is fixed by applying a mounting method. The attachment method and the area and shape of the fixed portion (hereinafter referred to as attachment region) 15a are appropriately determined in consideration of the weight of the package or the tensile force acting during transportation. In the present embodiment, the attachment region 15 a is located below the chuck portion 8.

  2A and 2B are diagrams for explaining the operation of closing the chuck portion 8, in which FIG. 2A is a side sectional view of the vicinity of the top portion 4 viewed from the IIa direction in FIG. 1, and FIG. FIG. 5C is a perspective view schematically showing the packaging bag 1 in a state where the chuck portion 8 is closed. FIG. After taking out the necessary number of sanitary products, the opposing side surface portions 6a and 6b of the rising portion 6 are brought close to each other as shown by the arrows in FIG. 2A, and the elements 8a and 8b are moved as shown in FIG. By engaging each other, a state as shown in FIG. In the present embodiment, the engaged elements 8a and 8b are located above the slit-shaped opening 7 'formed by breaking the opening line 7. Accordingly, as shown in FIGS. 2B and 2C, the opening 7 ′ is covered by the rising portion 6 and is not exposed to the outside, so that intrusion of foreign matter through the opening 7 ′ is effectively prevented. Become. Further, even if a foreign object exists between the opposing side surface parts 6a and 6b of the rising part 6 above the closed chuck part 8, the foreign object falls on the top surface part 5 when the chuck part 8 is opened, so immediately. It does not enter the body 3. At this time, if the opening 7 ′ has a slit shape, the intrusion into the body 3 is more effectively prevented. According to the present embodiment, the inside of the packaging bag can be protected from intrusion of foreign matter, and unused sanitary goods can be kept clean.

  Further, when the operation of closing the chuck portion 8 is performed in this way, the attachment region 15a of the handle 15 is located on the outer surface 6o of the rising portion 6, so that both the elements 8a and 8b interfere with the handle 15. There is nothing to do. Therefore, it is possible to perform an operation in which the opposing side surface portions 6a and 6b are brought close to each other and the elements 8a and 8b are engaged with each other as they are. On the other hand, in the configuration in which the attachment region 15a is located on the same inner surface as the chuck portion 8, precise positioning is necessary so that they do not overlap when the packaging bag 1 is manufactured, and the manufacturing process may be complicated. . Also, even if the chuck part is arranged above the attachment area so that the attachment area and the chuck part do not overlap, it takes time to fold the handle part inward of the packaging bag in order to avoid interference with the chuck part. It will be.

Next, a preferable arrangement of the chuck portion 8 in the present embodiment will be described.
3A is a side sectional view of the packaging bag 1 viewed from the IIIa direction in FIG. 1, and FIG. 3B is a top view of the packaging bag 1 (however, the handle 15 is not shown in FIG. 3B). Is). In the present embodiment, as shown in FIG. 3A, a gap L <b> 2 is provided between the sanitary article 2 and the top surface portion 5 accommodated in the packaging bag 1. That is, by providing the gap L <b> 2 in this way, a grip allowance can be formed on the top surface portion 5 of the packaging bag 1. The gap L2 for forming the grip allowance can be set appropriately. For example, the gap L2 can be set to one half or more of the substantially rectangular short side L1 (FIG. 3B). In this case, the interval (height) L3 between the housed sanitary product 2 and the chuck portion 8 is such that the opposing side surface portions 6a and 6b of the rising portion 6 corresponding to the long side of the substantially rectangular shape are pulled in the short side direction. Is closed (the elements 8a and 8b are engaged), L3> L2 ≧ (1/2) L1 should be satisfied.

  Furthermore, the chuck portion 8 is preferably provided at a position where a finger can easily reach when the user engages the elements 8a and 8b. Therefore, in the first embodiment described above, the chuck portion 8 is arranged in the vicinity of the upper edge of the rising portion 6.

  However, when it is desired to provide the chuck portion 8 at a position other than the vicinity of the upper edge as required, the chuck portion 8 is provided on the inner side surface 6i of the rising portion 6 and the attachment region 15a is provided on the outer side surface of the rising portion 6. The technical idea that it is provided in 6o is preferably compatible.

  FIG. 4 is a cross-sectional view schematically showing a part of the rising portion 6. When the chuck portion 8 is provided above the position of a certain attachment region 15 a, the case is provided at the same position. The cases provided below and below are indicated by reference numerals 8h, 8m and 8l, respectively. As is apparent from this figure, regardless of the position of the chuck portion 8, the opposing side surface portions 6 a and 6 b are brought close to each other as indicated by the arrows, and the chuck portion 8 is closed without interfering with the handle 15. It can be performed. In other words, the attachment region 15a and the chuck portion 8 can be determined independently of each other, so that the degree of freedom of the arrangement can be increased, and the attachment region 15a and the chuck portion 8 can be arranged at preferred positions according to design or manufacturing requirements. become able to.

<Other embodiments>
The present invention is not limited to the first embodiment and the modification described above.

  In the first embodiment described above, the gap L2 is set on the assumption that a grip margin is formed on the top surface portion 5 of the packaging bag 1, but this is not essential. In other words, the sanitary product 2 may be integrated over the entire space from the bottom surface portion of the body portion 3 to the top surface portion 5 of the top portion 4. In order to enable the operation of closing the chuck portion 8, L3> (1/2 It suffices if it is defined to be L1. Further, if the packaging bag has a substantially square shape in a top view, L3 can be defined based on the length of one side of the square.

  Moreover, in 1st Embodiment, although height L3 was prescribed | regulated from the position of the sanitary goods 2 accommodated in the packaging bag 1 before opening, since the opening line 7 has performed the obstruction | occlusion function before opening. It is not a requirement that the chuck portion 8 is closed. Therefore, for example, in the case of a packaging bag accommodated in a state where sanitary products are stacked, even if the height L3 is not ensured at the stage before opening, the height is increased when the uppermost sheet is taken out. It is sufficient that the length L3 is secured.

  Further, in the first embodiment, the chuck portion 8 is continuously arranged over the entire circumferential direction of the inner side surface 6i. However, as long as the chuck portion 8 has a desired closing function, the circumferential direction of the inner side surface 6i. It may be arranged only on a part of the inner surface or may be arranged intermittently over the entire circumferential direction of the inner side surface 6i.

  Further, the basic technical idea of the present invention is that the rising portion 6 has two side surfaces of an inner side surface 6i and an outer side surface 6o, and the chuck portion 8 and the attachment region 15a are arranged on different side surfaces. . That is, unlike the first embodiment, the configuration in which the chuck portion 8 is disposed on the outer surface 6o of the rising portion 6 and the attachment region 15a is disposed on the inner surface 6i of the rising portion 6 is not excluded.

  FIG. 5 is a cross-sectional view schematically showing a part of the rising portion 6 in order to explain the second embodiment having such a configuration, and (a) shows a state before the chuck portion 8 is closed. (B) has shown the closed state. When the chuck portion 8 is positioned on the outer surface 6o of the rising portion 6 as shown in FIG. 5A, the rising portion 6 is folded back to the top surface side as shown in FIG. 5B, and the elements 8a and 8b are moved. Can be occluded. With the folding operation at this time, the handle 15 is also naturally folded back to the top surface side and positioned in the internal space, so that the elements 8a and 8b can be engaged without causing interference with the handle 15. it can. This is the same regardless of the position of the chuck portion 8 with respect to the attachment region 15a as shown in FIG.

  Furthermore, in the first embodiment, in the packaging bag that has a substantially rectangular shape when viewed from the top, the handle 15 is attached to each of the side surface portions 6a and 6b connected to the pair of opposing long sides of the substantially rectangular shape. However, the attachment position and form of the handle 15 can be determined as appropriate. For example, it is possible to attach at least one end of the belt-shaped member to the side surface portions 6 a and 6 b, that is, to provide a handle having a configuration in which the belt-shaped member straddles the top surface portion 5. Moreover, a handle may be attached to the side part connected to a pair of opposing short sides of a substantially rectangular shape. In any case, the basic technical idea of the present invention in which the chuck portion 8 and the attachment region 15a are arranged on different side surfaces of different rising portions 6 also contributes to increase the degree of freedom of the attachment position of the handle. It is.

  In addition, in the first embodiment, the perforated line-shaped opening line is formed on the top surface part 5, but instead of this, the opening line in the form of an easily breakable part made of a material that can be easily broken. May be provided on the top surface of the packaging bag. Further, the present invention can be applied to a packaging bag in which both edges are grasped and opened without forming an opening line.

  In the first embodiment, the chuck portion 8 and the opening line 7 are formed so that the closed chuck portion 8 and the opening 7 ′ are parallel to each other. However, for example, the opening line 7 may be formed in a direction parallel to the substantially rectangular short side, while the chuck portion 8 may extend in the long side direction.

  In addition, in 1st Embodiment, although the attachment area | region 15a of the handle 15 was made into the outer surface 6o of the standing part 6, it is not restricted to this. The handle 15 may be attached to the outer surface of the trunk 3 at a position below the top surface. That is, the handle 15 can be attached to any desired position on the outer surface of the packaging bag 1 formed by the rising portion 6 and the trunk portion 3.

  Further, the arrangement of the opening / closing portion 8 can be provided not only on the side surface portion where the rising portion 6 faces, but also on the top surface portion 5. In other words, as described above, if the gripping allowance is formed by using the packaging body 100 in which a gap is provided between the top surface portion 5 and the sanitary article to be accommodated, the top surface portion 5 is allowed to loosen. become. Therefore, even if the chuck portion 8 is disposed on the top surface portion 5 and there is a slack, the user grasps both sides of the opening 7 'caused by the breaking of the opening 7 and draws them together to engage the elements 8a and 8b with each other. be able to.

  FIG. 6 shows a third embodiment of the present invention, in which a handle 15 is attached to the outer surface of the body 3 at a position below the top surface, and the opening wire is in the vicinity of the opening wire 7 of the top surface portion 5. 7 and a configuration in which a pair of elements 8 a and 8 b are provided in parallel with the structure 7. However, it is not essential that these configurations be adopted at the same time.

  In any case, the provision of the present invention, that is, the attachment area of the handle on one side of the outer surface of the packaging bag and the area defined by the rising part and the top surface part, and the opening / closing part on the other side. According to the provision of distribution, it is possible to relax the restrictions on the manufacturing of the packaging bag, and to make a preferable design of the packaging bag in consideration of the operability when closing the opening / closing part.

  Furthermore, in the above-described embodiment, an example in which a male and female bite type chuck portion is used as the opening / closing portion has been described, but it goes without saying that an opening / closing portion in the form of a hook-and-loop fastener can also be used.

  Furthermore, in the above description, the packaging bag suitable for accommodating a sanitary article and the packaging body which accommodated the goods in the packaging bag were illustrated. However, the present invention can also be applied to a packaging bag or package for containing other articles, and in particular contains articles (food, medicine, medical products, etc.) that are preferably shielded from the atmosphere during storage after opening. It is suitable for doing.
