Modal packaging unit for individually packaging absorbent item is to include two folding axis, vertical
To edge and the rectangular sheet of transverse edge.This embodiment is as shown in Figure 9.Packaging unit 301 is
Including packaging unit being divided into the 310, second area, the first area 311 and two of the 3rd area 312
Folding axis 309, the sheet material of 309'.Each area includes inner margin portion 305,305', 308 and outer rim
Part 306,306', 307.As it is shown in figure 9, first and the 3rd peripheral edge portion 306,307 in area
Be respectively provided with binding agent 12, simultaneously first and the 3rd the inner margin portion 305,308 in area respectively without viscous
Mixture.The pattern of adhesive in the second area 311 and first and the 3rd binding agent figure in area 310,312
Case is complementary, therefore defines checkerboard pattern.In other words, the peripheral edge portion in the second area 311
306' does not contains binding agent, and inner margin portion 305' in the second area 311 possesses binding agent.This also means
As shown in Figure 6 when sheet material folds around folding axis 309,309', the first of carrying binding agent 12
The peripheral edge portion 306 in area 310 or the peripheral edge portion 307 in the 3rd area 312 and the second area 311
In contact without the peripheral edge portion 306' of binding agent, depend on first and the 3rd in area 310,312
Which contacts with the second area 311.Therefore, in the second area 311, binding agent 12 is carried
Inner margin portion 305 without binding agent or the 3rd area 312 in inner margin portion 305' and the first area 310
The inner margin portion 308 without binding agent contact.As can be seen from Figure 10, the width pair of sealing area
Should be in adhesive portion 306, the summation of 305' width.It should be noted that, the fold sequence of packaging unit is
Incoherent.Such as, packaging unit can fold around the second folding axis 309', makes the 3rd area 312
Contact with the second area 311, seal peripheral edge portion 307,306' and inner margin portion 308,305'.
Packaging unit folds then around the first folding axis 309', makes the first area 310 and the 3rd area 312
Outer surface contact, therefore seal packaging unit (Figure 10).Fold sequence also can be contrary.This is
The biggest advantage, because when the packaging unit of the present invention is used for abandoning, user need not be with any spy
Definite sequence FOLD AND PACK unit just can obtain and pack closely.Packaging unit will provide suitable with folding
Tight and the packaging of health that sequence is unrelated.
In order to obtain packaging closely, transverse edge 304' and 304** of packaging unit 301 possesses bonding
Agent 12.When two transverse edge 304' and 304** possess binding agent, fold sequence is described above as
Incoherent.It is further envisioned that only one transverse edge possesses binding agent.In this case, it is necessary to around
The folding axis being positioned closest to the transverse edge without binding agent starts folding, thus includes bonding
The area of the lateral edge portion that agent covers forms lid and is positioned at the bonding of lateral edge portion office
Agent packs unit.
In order to be conducive to opening packaging, the part of adhesive coverage is positioned such that packaging unit 301
Corner part 21 at least one be free from binding agent, therefore define once open packaging,
The grasping tab grasped by user.Additionally, when packaging unit is sealed, turning without binding agent
Angle part 21 is used as outlet (Figure 10).
As it has been described above, the width of sealing area is the adhesive coverage partial width in the first and second areas
Summation.On more scores than one, it may be desirable to minimize the quantity of binding agent and the width of lapping.
If the width of two adjacent zone inner binder covering parts is halved in the way of as shown in figure 11,
Then can realize above-mentioned purpose.Packaging unit 401 have packaging unit is divided into the first area 410,
Second area 411 and two folding axis 409, the 409' in the 3rd area 412.As can be seen from Figure 11,
The adhesive coverage portion of two adjacent zones (be in this case second and the 3rd area 411,412)
Divide the width bonding corresponding to remaining area (being the first area 410 in this case) of 405' and 407
The half of the width of agent covering part.Adhesive coverage part 405' in the second area 411 and the 3rd ground
Adhesive coverage part 407 with 412 is complementary, and this is critically important.If pattern of adhesive such as figure
Shown in 11 and 12, if packaging unit is intended to be reopened i.e. when packing untapped articles for use, it is necessary to enclose
Start around the folding axis being positioned between the area with binary adhesive coverage part and fold.
Otherwise, the adhesive coverage part 406 in the first area 410 will be covered with the binding agent in the second area 411
Cover 405' contacts, thus eliminates the probability opening packaging unit again.
