DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiment 1 Referring now to the drawings, Fig. 1 is an enlarged cross-sectional view o~ one unit o-~ a package of one embodiment according to the present invention.
Fig. 2 is a plan view o~ this embodiment of the package of the present invention. Fig. 3 is a graphical presentation showing the preserva~tion effect of this package according to the present invention in comparison with the prior art.
In this embodlment, a package 1 comprises a moisture-impermeable sheet material 2 laminated by, ~or example, aluminum foil or a plastic film, and a .~ "
.:. ~ - I
:: j ., ,r , , ~. , ; :..... :.
. :~ ".: , '' . , moisture-impermeable package -film 3 sealedly bonded onto the sheet material 2, for example by hea-t seal:ing.
The package -film 3 is made, -for example, of moisture-impermeable plas-tic :~ilm, being preferably transparent or translucent. For exapmle, the package -film 3 maY be made o~ transparent resin such as polyvinylchloride film having moisture-impermeability.
As shown in Figs. 1 and 2, the package -film 3 in this embodiment is formed to be provided with spaces 5 (the first spaces) to respectively con-tain capsules 4 as articles to be packed, spaces 7 (the second spaces) -to respectively contain drying ageIlts 6, and communlcatlng spaces 8 to respectively communicate the spaces 5 and the spaces 7 each other, in concave shapes, wh:Lle the package film 3 is sealedly bonded to the sheet material 2 at all portions except -for these spaces 5, 7 and 8.
The sheet material 2 can be broken, for example, by the nail o-f person's ~inger to take out the capsule 4.
The communicating space 8, as shown in Figs. 1 and 2, is lower in height and narrower in width than the spaces 5 and 7, de~lning a constricted part, and the cross-sectional area o-f the communicating space 8 is smaller than the outside dimensions o~ -the capsule 4 and the drying agent 6. There-fore, the capsule 4 or the drying agent 6 received in the space 5 or 7 does not 7 ~ ~
move from its space 5 or 7 to the communicated space 7 or 5, thus~ both capsule 4 and drying agent 6 are contained indepen~ently in respective spaces 5 or 7 without contac-ting each other.
Further, the package 1 in this embodiment is scored separation lines 9, ~or example, as intermittently cut lines or continuous groove lines to define each unit la so that it is possible to easily separate a combination o~ one capsule 4 and drying agent 6 as one unit la -from other unit la. In this embodiment, for purpose of an example, one package 1 contains ten units la. However, it does not mean to restrict to ten. Thus, it is convenient for separating and carrying by one or more units because it is possible to separate easily every each units la.
The whole package 1 is contained in the bag 10, as an outside bag comprising a moisture-impermeable material such as aluminum -foil etc.
Next, the method o-~ production and -the operation o-f this embodiment are explained.
At ~irst, in case of producing the package 1 o~ the embodiment, the spaces 5 to contain capsule, the spaces 7 to contain drying agent, and the communicating spaces 8 are formed in concave shapes in the moisture-impermeable package -film 3 of a plastic -~ilm.
. .
' i : ' ' ~' ' ' ' ~i , ' . ' ~ ' ' ' .' ' .
8 ~ J~ 3 Then, the capsules 4 and the drying agents 6 with prescribed largeness are respectively set into the spaces 5 to contain capsule and the spaces 7 to contain drying agent. And in this state, all portions of the package -~ilm 3 except -for the spaces 5, 7 and 8 are sealed with the moisture-impermeable sheet material ~ by using a method such as the heat sealing method. Next, the separation lines 9 such as intermittently cut line or continuous groove line are provided for the package 1 to make every one combination of a capsule 5 and a drying agent 6 as one unit la.
For the purpose o-~ sale etc., the package 1 thus produced is contained into the bag 10 as outside bag, having moisture-impermeability, by every prescribed number o~ unit la, for e~ample ten units la.
Further, the production process described above ~ay be carried out in automatic manu~acturing line, not shown, as o~ the substantially totally automated manufacturing work.
According to this embodiment, the space 5 to contain capsule 4 is communicated through the communlcating space 8 to the space 7 to contain drying agent 6, and both the sheet material 2 and the package -film 3 heat-sealed to each other have the moisture-impermeability, there-eore the dryness of the capsule , : .' .~ ;
c3 ~ $-, r1 ~
is controlled Just by dry:Lng agent 6 even a-fter the opening o-f the outside bag, and the capsule 4 does not absorb any moisture from the outside. There~ore, when the drying agent is selected properly in its kind, amount, largeness and shape to obtain the best dryness o-f the caps-ule 4, and the capsule 4 and the drying agent 6 are set into their own spaces 5 and 7 respectively, then the capsule 4 is maintained usually at the best dryness or water balance, and un-favorable phenomenon such as deterloration of the content o-f the capsule 4 by intrusion o-f moisture or cracking Oe the capsule 4 by excessive dry:Lng can be prevented .from occuring.
Further, the package 1 in this embodiment is made up of the moisture-tmpermeable tight-sealed uni-ts, i.e.
la units, therefore it is convenient to separate each unit la at the separation line 9 and to carry with these separated units.
Moreover, in th-ls embodiment, the capsule 4 is not contaminated by the drying agent 6, because the communication space 8 has smaller cross sectional area than both outside dimentions o-~ the capsule 4 and the drying agent 6 and communicates the spaces 5 and 7 which contain respectively the capsule 4 and the drylng agent 6 wi-thout contacting each other. Further, an accident o-f eating the drylng agent 6 in place O-r the capsule 4 . .
.
1 o ~ 3 ~i ~
can be prevented, because the drying agent 6 is not taken Ollt simultaneously with -the capsule 4, when a portion of the sheet material 2 corresponding to the containing space 5 is broken to take out the capsule 4.
The inventors compared -the operatlonal effects ot`
the package 1 according to the present invention with the prior art described in Fig. 6 and obtained the results shown in Fig. 3. In this comparison, stability of a powdery inhalant agent in capsule which is preserved at 25'C-83% RH is evaluated -~or respective packages by the distribution ratio o~ KI-111 onto Stage -2~3~4 o-f MLI (Multi-Stage Liquid Impinger) Yollowing the time elapsed Just a-~ter opening the bags 10 and 102 as outside ba~s. According to this co~nparison, the package 1 showed the sufficient stability through whole 28 days, but in the prior art, the distribution decreased since a day a~ter opening and showed much lower value than the standarcl value (30%) at 3 days. By this comparison. it is proved tha-t we obtain extremely favorable stability in the package o-~ the present invention compared with the conventional package.
Embodiment 2 In Fig. 4, is shown an enlarged cross-sectional view of another embodiment o-~ the package according to the present invention. This Embodiment 2 is 3 ;~ ~, substantially same as Embodiment 1 except for containing, for example, the pills 4a in respective pill containing spaces 5a (the first space) in place o-~capsules as articles to be packed.
Even in this Embodiment 2, the properties including largeness, kind and shape of the drying agent 6 can be selected depending on the desired rate of dryness of the pill 9.
The excellent various operational effects explained in Embodiment 1 are also obtained in this Embodiment 2.
Embodiment 3 Fig. 5 shows the enlarged cross-sectional view o~
~urther embodiment o~ the package according to the present invention. The package 1 in this Embodiment 3 is an example in which the powder 4b as an article to be packed is set into a powder containing bag 4c having moisture permeability, and then it is contained in a powder containing space 5b (the first space).
In this Embodiment 3, also the excellent operational e~fects are obtained substantially same to above Examples 1 and 2.
Further, when the powder containing bag 4c in this Embodiment 3 is made of, for example, an edible film, one can take the :Lnner powder 4b by taking the powder conta:Lning bag 4c itsel-f after taking :Lt out by break:Lng ' 12 '~ '5 the sheet material 2 with nail.
As described above, -the inventlon made by the inventors is explained based upon the embodiments.
However, it should be unders-tood that the present invention i9 not restrlcted to above embodiments and many variations are possible without departing -from the scope of the invention.
For example, shapes and allocation o-f the spaces for articles to be packed and drying agents, or of communication spaces are not restricted by the embodiments. The constituent materials o-~ sheet material 2 and a package film 3 can also be variably selected.
The above description is made to the cases where the present invention is applied to the packages o-f pharmaceutical capsules, pills and powder, however, the invention is not restricted to those cases, and, for example, it can also be applied to foods, agric-ultural chemicals, etc. with other product shape like a globule etc.
~ ffects attained by the representative invention disclosed above are outlined as -follows.
1) The package comprises the moisture-impermeable sheet materia:L and the moisture impermeable package f:ilm which is sealedly bonded to the sheet material, and has :
the -first spaces respectively containing articles to be packed, the second spaces respectively containing drying agents, and the communicating spaces respec-tively communicating the first and the second spaces each other, between the sheet material and the package -film, so that dryness or water balance of the packed articles can be always kept at the most suitable condition by the drying agent even after the opening of the outside bag and good quality o-~ the article can be maintained just -until it is used.
2) According to 1), the deterioration of the packed articles brought by insuf-ficient drying and the cracking o-f the packed article caused by excessive drying, can be prevented effectively by adJusting in advance the drying capability o-f the drying agent by selecting i-ts largeness, kind, amount, and shape.
3) According to and in addition to 1), any unfavorable accidents caused by direc-t contacting of -the packed article and the drying agent can be eli~inated, as the cross sectional area of the communicating space is smaller than the outside dimensions o-~ both the packed article and the drying agent which are contained in the first and the second spaces respectlvely without contact each other.
SUMMARY OF THE INVENTION
One purpose of the present invention, there-fore, is to offer packaging technology by which desired water balance or dryness can be maintained and dryness of the packed products can be reliably ad~usted, even if the outside bag is unsealed.
Another purpose o-~ the invention is to of-~er packaging technology which can realiably maintain the quality o-f the packed products.

Next, the separation lines 9 such as intermittently cut line or continuous groove line are provided for the package 1 to make every one combination of a capsule 5 and a drying agent 6 as one unit la.
For the purpose o-~ sale etc., the package 1 thus produced is contained into the bag 10 as outside bag, having moisture-impermeability, by every prescribed number o~ unit la, for e~ample ten units la.
Further, the production process described above ~ay be carried out in automatic manu~acturing line, not shown, as o~ the substantially totally automated manufacturing work.
According to this embodiment, the space 5 to contain capsule 4 is communicated through the communlcating space 8 to the space 7 to contain drying agent 6, and both the sheet material 2 and the package -film 3 heat-sealed to each other have the moisture-impermeability, there-eore the dryness of the capsule , : .' .~ ;
c3 ~ $-, r1 ~
is controlled Just by dry:Lng agent 6 even a-fter the opening o-f the outside bag, and the capsule 4 does not absorb any moisture from the outside. There~ore, when the drying agent is selected properly in its kind, amount, largeness and shape to obtain the best dryness o-f the caps-ule 4, and the capsule 4 and the drying agent 6 are set into their own spaces 5 and 7 respectively, then the capsule 4 is maintained usually at the best dryness or water balance, and un-favorable phenomenon such as deterloration of the content o-f the capsule 4 by intrusion o-f moisture or cracking Oe the capsule 4 by excessive dry:Lng can be prevented .from occuring.
Further, the package 1 in this embodiment is made up of the moisture-tmpermeable tight-sealed uni-ts, i.e.
la units, therefore it is convenient to separate each unit la at the separation line 9 and to carry with these separated units.
Moreover, in th-ls embodiment, the capsule 4 is not contaminated by the drying agent 6, because the communication space 8 has smaller cross sectional area than both outside dimentions o-~ the capsule 4 and the drying agent 6 and communicates the spaces 5 and 7 which contain respectively the capsule 4 and the drylng agent 6 wi-thout contacting each other. Further, an accident o-f eating the drylng agent 6 in place O-r the capsule 4 . .
.
1 o ~ 3 ~i ~
can be prevented, because the drying agent 6 is not taken Ollt simultaneously with -the capsule 4, when a portion of the sheet material 2 corresponding to the containing space 5 is broken to take out the capsule 4.
The inventors compared -the operatlonal effects ot`
the package 1 according to the present invention with the prior art described in Fig. 6 and obtained the results shown in Fig. 3. In this comparison, stability of a powdery inhalant agent in capsule which is preserved at 25'C-83% RH is evaluated -~or respective packages by the distribution ratio o~ KI-111 onto Stage -2~3~4 o-f MLI (Multi-Stage Liquid Impinger) Yollowing the time elapsed Just a-~ter opening the bags 10 and 102 as outside ba~s. According to this co~nparison, the package 1 showed the sufficient stability through whole 28 days, but in the prior art, the distribution decreased since a day a~ter opening and showed much lower value than the standarcl value (30%) at 3 days. By this comparison. it is proved tha-t we obtain extremely favorable stability in the package o-~ the present invention compared with the conventional package.
Embodiment 2 In Fig. 4, is shown an enlarged cross-sectional view of another embodiment o-~ the package according to the present invention. This Embodiment 2 is 3 ;~ ~, substantially same as Embodiment 1 except for containing, for example, the pills 4a in respective pill containing spaces 5a (the first space) in place o-~capsules as articles to be packed.
Even in this Embodiment 2, the properties including largeness, kind and shape of the drying agent 6 can be selected depending on the desired rate of dryness of the pill 9.
The excellent various operational effects explained in Embodiment 1 are also obtained in this Embodiment 2.
Embodiment 3 Fig. 5 shows the enlarged cross-sectional view o~
~urther embodiment o~ the package according to the present invention. The package 1 in this Embodiment 3 is an example in which the powder 4b as an article to be packed is set into a powder containing bag 4c having moisture permeability, and then it is contained in a powder containing space 5b (the first space).
In this Embodiment 3, also the excellent operational e~fects are obtained substantially same to above Examples 1 and 2.
Further, when the powder containing bag 4c in this Embodiment 3 is made of, for example, an edible film, one can take the :Lnner powder 4b by taking the powder conta:Lning bag 4c itsel-f after taking :Lt out by break:Lng ' 12 '~ '5 the sheet material 2 with nail.
As described above, -the inventlon made by the inventors is explained based upon the embodiments.
However, it should be unders-tood that the present invention i9 not restrlcted to above embodiments and many variations are possible without departing -from the scope of the invention.
For example, shapes and allocation o-f the spaces for articles to be packed and drying agents, or of communication spaces are not restricted by the embodiments. The constituent materials o-~ sheet material 2 and a package film 3 can also be variably selected.
The above description is made to the cases where the present invention is applied to the packages o-f pharmaceutical capsules, pills and powder, however, the invention is not restricted to those cases, and, for example, it can also be applied to foods, agric-ultural chemicals, etc. with other product shape like a globule etc.
