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, a perforated opening line 7 extending in parallel with the long side of the substantially rectangular shape is provided, and an opening of the packaging bag 1 is formed by breaking this. The In the present embodiment, by providing a gap between the top surface portion 5 and the sanitary article to be accommodated, a grip that facilitates the operation of pulling both sides of the unsealing line 7 provided on the top surface portion away from each other and breaking them. A teenager 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.

  On the other hand, on the rising portion 6 of the top portion 4, a chuck portion 8 in the form of a plastic bite is provided as an opening / closing portion capable of opening / closing the inside of the packaging bag 1. The chuck portion 8 is arranged along the inner periphery so as to face the space on the top surface portion 5 surrounded by the rising portion 6, and is a male type that can be engaged with each other as a pair of engaging portions that can engage 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.

  2A and 2B are diagrams for explaining the function and operation of the chuck portion 8, wherein FIG. 2A is a side sectional view of the vicinity of the top portion 4 as viewed from the direction IIa in FIG. 1, and FIG. 2B is a state in which the chuck portion is closed. FIG. 5C is a perspective view schematically showing the packaging bag 1 in a state where the chuck portion 8 is closed. 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.

  On the other hand, when the configuration disclosed in Patent Documents 1 and 2 is adopted, the foreign matter accumulated in the upper portion of the packaging bag in the state where the chuck portion is closed is left inside the packaging bag as it is when the chuck portion is opened. There is a risk of falling. Moreover, since this embodiment is not the structure which cuts and opens the upper end of a packaging bag like patent document 1, it prevents the infant from putting this in a mouth or swallowing it by leaving a cut piece. can do.

Next, the preferable arrangement | positioning position of the chuck | zipper part 8 in this embodiment is demonstrated.
3A is a side sectional view of the packaging bag 1 as viewed from the direction of IIIa in FIG. 1, and FIG. 3B is a top view of the packaging bag 1. 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. Further, in order to facilitate the opening / closing operation, the chuck portion 8 is preferably provided at a position near the upper edge of the rising portion 6.

  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.

  Furthermore, 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 sealing function before opening In addition, 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. If the handle is attached to the rising portion 6, the attachment position of the handle can be determined in consideration of the height L3 to be secured.

  In addition, 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.

  Further, the arrangement position of the pair of elements 8a and 8b constituting the chuck portion 8 is not limited to the inner periphery of the rising portion 6, but may be along the outer periphery. In this case, the occlusion operation can be performed by folding back the upper edge portion of the rising portion 6.

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

  For example, it is not essential to provide the gap L2 between the housed sanitary product 2 and the top surface portion 5, but providing the gap L2 leads to an increase in the degree of freedom of the arrangement position of the chuck portion 8.

  4 (a) and 4 (b) are a perspective view and an explanatory view of an operation of a main part of the second embodiment of the present invention, focusing on this point. In the present embodiment, as shown in FIG. 4A, a chuck portion 8 is disposed in the vicinity of the opening wire 7 of the top surface portion 5 in parallel with the opening wire 7. Providing the gap L2 to form a grip allowance allows the slack of the top surface portion 5. If there is a slack, as shown in FIG. 4 (b), the user can grab both sides of the opening 7 'and draw them together to engage the elements 8a and 8b with each other.

  In the first and second embodiments, the present invention is applied to a packaging bag in which the top portion 4 has a top surface portion 5 that faces the bottom surface portion of the trunk portion 3 in parallel. It can also be applied to shaped packaging bags.

  FIG. 5 is a perspective view showing a third embodiment of the present invention, and shows a top portion 4 that covers the top surface of the trunk portion 3 and has a roof shape having an inclined surface. As shown in FIG. 5, an opening line 7 is formed on one inclined surface, and a chuck portion 8 is disposed in the vicinity thereof in parallel with the opening line 7. If the slack of the inclined surface is allowed, the user grasps both sides of the opening 7 ′ formed after the opening line 7 is broken and pulls the elements 8a and 8b together, as in the second embodiment. Can be occluded with each other.

  In addition, although the perforated line has a perforated shape, instead of this, an open 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.

  Furthermore, although the example using the male and female occlusion type chuck | zipper part as an opening / closing part was demonstrated, of course, the opening / closing part of a hook-and-loop fastener form 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.
