Description
The present invention concerns a liner bag used for loading grain cargoes such granular or powdery goods, for example, molt to a container and, more in particular, it ;`
relates to a liner bag capable of unloading such goods :
charged in a bag main body attached to the inside of a container easily and completely, without downwardly slanting the container toward to side of a container's door. ~
When transporting grain cargoes such as granular or ~ -powdery goods ~hereinafter simply referred to as goods) by using a dry container, etc., a bag main body has been attached usually to the inside of a container and the goods ~ ;-are charged in the bag main body. The present applicants ~; have previously proposed such a kind of liner bag in, for example, Japanese Utility Model Laid-Open No. Sho 61-45392, March 26, 1986. ~;
.,~
., ~ . .
~ By the way, in the liner bag of this kind, it is ;~
.~ ~
; necessary to slant the container downwardly toward the side : . ,~' , of a container's door upon unloading or discharging goods.
However, in a case of a large and long container such as a 40 feet~jlength container, there has been a proble~ that the. ~ -~
5, ~-~25 ~
~ ..
container can not be slanted easily, or the container can not be slanted to a required angle if the height of ceiling is low.
In view of the above, the present applicants have previously proposed a liner bag used for a container as disclosed in, for example, Japanese Utility Model Laid-Open Hei 1-107596, July 20, 1989, in which a draw sheet or a pull-out sheet is disposed at the inside of a bag main body, so `` `
that flowable goods can be unloaded by merely drawing or pulling out the pull-out sheet toward a container's door ~ without slanting the container. i~
`~ In our proposed liner bag having the pull-out sheet as described above, a rear end of a bottom face (on the side of " ~
the door) of the bag main body is extended toward the side of ~ '''' ~ "'`'t'~' the door beyond the rear face of the bag and a rear end of the pull-out sheet ~on the side of the door) is extended out of the bag main body through an opening formed in the lower ~ `~
end of the front face. Both of the extended portion of the `~
bag and the pulled-out portion of the sheet are folded back and disposed to the outer surface in the lower portion of the front face of the bag main body.
By the way, in a liner bag of a structure that the ` ` -outer side of the front face is supported by bulkhead detachably provided to one end of a container on the side of its door, there has been a problem that the extended portion of the bag main body and the pulled-out portion of the pull- ~ -S out sheet may hinder the mounting of the bulkhead or hinder the smooth operation of discharging goods.
Further, in a liner bag having the pull-out sheet, since a bag main body and a pull-out sheet are constituted separately, the pull-out sheet may, undesirably, be displaced from the bottom face of the bag main body when the latter folded before used is spread and attached to the inside of ;~ the container. Further, when the goods are charged into the -~
bag main body attached to the inside of the container, the pull-out sheet may possibly be displaced by impact shocks upon charging the goods.
Furthermore, when the pull-out sheet is drawn or pulled out toward the door of the container for unloading the goods there may be risk, if the goods are not loaded evenly, the I both side edges of the pull-out sheet are gathered toward the inside, failing to discharge the goods completely.
The present invention provides a liner bag used for a container capable ~; - 3 - ~ -,, ~ .
of attaching a bag main body easily to the inside of the container even when a bulkhead is used therein and also capable of facili~ating the operation of unloading goods.
The present invention also provides a liner bag used for ~ ;
a container capable of preventing the lower end of a rear `
face of the liner bag from protruding toward the side of a container's door by a pressure exerted from goods.even in a structure that an opening for pulling-out a rear end of a pull-out sheet from a bag main body is formed in the lower end of a rear face of the bag.
Further, the present invention provides a liner bag used for a container capable of completely preventing the pull-out sheet from being displaced when a folded bag main body is `
lS spread and attached to the inside of the container or when goods are charged to the inside of the bag main body, as well as capable of preventing both side edges of the pull-out sheet from gathering toward the inside and being creased upon pulling the pull-out sheet to the side of the door even if the goods are not loaded evenly.

More particularly, the present invention provides a liner bag used for a container having a door at its longitudinal rear end, in which the liner bag has~
, , -:
a main body for lining the inside of said container and comprising a bottom face, a pair of side faces, a front face ``
and a rear face and wherein, when the liner bag is positioned ~.
within the container, said bottom face is opposed at least to ^~ a bottom wall of the container, said side faces are opposed ¦; to respective side walls of the container, said front face is ;
opposed to the front wall of the container a~d said rear face `~' is opposed to the door of the container; . ;.~-- 4 ~
~ ~ ,.", ~
~ 20Q3257 a pull-out sheet laid over the bottom face of said bag main body for transporting grain cargoes loaded on the upper surface of said sheet in a direction towards the door when said sheet is pulled by its rear end;
an extended portion of the rear end of the bottom face of said bag main body, said extended portion extending beyond -the position of the rear face in a direction towards the door, when the liner bag is positioned within the.container, wherein the extended portion of said bottom face is made foldabIe, and wherein the rear end of said pull-out sheet is ~ ;
pulled out of said bag main body through an opening formed in `
the lower end of the rear face of said bag main body and the pulled out portion of said pull-out sheet is made foldàble independently of the extended portion of said bottom ~ace;
and . :; .~ : ~:::
means for securing the folded extended portion of the bottom face of the bag main body, together with the folded pulled-out portion of said sheet, to the surface of a bulkhead device detachably mounted to the rear end of said container, the arrangement being such that the latter portion is situated inside the former portion.
In the present invention, since the pulled-out portion of the pull-out sheet and the extended portion of the bottom ~ ;
face are folded independent of each other and secured together to the surface of the bulkhead device on the side of ~ ;~
theldoor, the bag main body can be mounted easily to the inside of the container even in a case of using such bulkhead device and, in addition, handling upon discharging goods is ~ ~`
also easy. Further, since the extended portion of the bottom face and the pulled-out portion of the pull-out sheet are ~ secured together to the bulkhead device, with the latter i~; portion being situated inside the former portion, the pull-~ ~ 5 ~

As shown in Fig. 12, strings 52 bound to the ring :-belts 34 of the tongue 33 and ring belts 53 to which the ends of the strings 43 bound to the ring belts 44 are ;: secured are disposed respectively to the surface of the ~ ;
bulkhead sheet 48 on the side of the door 3 (this side -~
in Fig. 10).
OPERATION
'~ Operation of this embodiment having the foregoing constitution will be described.
Upon using the liner bag 9, the bag main body 11 is at first inserted into the dry container and the upper hooks 13 are engaged to the upper engaging metal fixtures 6 and ~ the lower hooks 18 are engaged to the lower engaging metal ;~ fixtures 5 respectively.
~; Then, the rear ends of the upper edge belts 12 (on the side of the door 3) are wound around and bound to the ,. ~ ' : .': ~'' -': ~ '' .: .' ~, ,, ', ' ' ' ~" ~' , , .' , 2003:~5~ ~ ~
upper engaging metal fixtures 8 and the rear ends Or -the ~ ;:
lower edge belt 17 (on the side Or the door 3) are wound -around and secured to the lower engaging metal fixtures 7.
Subsequently, both ends of the reta:Lner belt 37 are secured to the lower engaging metal rixtures 7 respectively. `~
Thus, the opening 28 below the lower end Or -the rear face lld is urged from above to prevent the goods charged in the bag main body 11 from leaking through the opening 28.
In addition, the lower end of the rear face lld is prevented ~rom being protruded outwardly toward the door 3 by the pressure from the goods though the opening 28 is disposed at the lower end Or the rear race lld.
Then, as shown in Fig. 12, the bulkhead 10 i8 mounted between the recessed grooves 4. In this case, the rear end of the pull-out sheet 21 and that Or the bottom face ;... ,.,~
lla are pulled out as shown in Fig. 5 below the bulkhead . :~
device 10 toward the side Or the door 3.
Then, as shown in Fig. 9, the rear end Or the bottom face lla i9 rolled and contained under the slippery sheet 20, while the rear end Or the pull-out sheet 21 is rolled with the core material 45 being inside and then contained between the bend piece 35 and the upper cover 36. Then, the strings 42 are bound to the ring belts 40 to fix the pull-out sheet 21 between the bend piece 35 and the upper , cover 36. In this case, since the pull-out sheet 21 is contained in its rolled state between the bend piece 35 and the upper cover 36, the upper surface of the sheet 21 is not exposed externally and thus free from contamination.
Further, since -the pull-out sheet 21 is secured in its rolled stake between the bend piece 35 and the upper cover 36, it can be secured easily along the outer surface Or the bulkhead device 10, while maintaining khe folded æhape. ~-~
Since the stitch line 39 inhibits the pull-out sheet 21 from rurther entering toward the rear face lld, if the binding Or the retainer belt 37 to the lower engaging metal 7 is loosened and the lower end o~ the rear ~ace lld protrudes outwardly, there i8 no trouble tha-t the pull-out . . :
sheet 21 is caught under the rear race lld and can not be -spread rlat as shown in Fig. 2.
~, , .
After the pull-out sheet 21 has been contained and secured between the bend piece 35 and the upper cover 36, the rolled portion Or the bottom face lla is once turned ,,i. , ;
below the slippery sheet 20. Specirically, as shown in Fig. 9, the left end of the bottom race lla i~ bent at a position near the right end Or the string 43 over the upper surrace Or the right end. Subsequently, the ætring 41 and the string 42 are bound to each other and the string 43 is bound to the ring belt 44. Thus, the rolled ends of the pull-out sheet 21 and the bottom face lla on the side Or the door 3 are integrally secured, wlth the ~ -~
~,, '.~; :' ';' - 18 - ~ ~ ~
;` 200~2S7 bottom race lla being underside.
Then, they are uprighted to the rear face of the bulkhead 10 and, as shown in Fig. 13, the strings 43 are bound to the ring belts 53 Or the bulkhead sheet 48. Thus, the rear end of the pull-out sheet 21 is secured to the - --;
bulkhead 10, with the outer surrace thereof being covered with the bottom face lla.
The tongue 33 at the lower edge Or the charging port `~
31 is wound around the upper end Or the bulkhead sheet 48 and then bound at the ring belts 34 with the s-trings 52, by which the tongue is fixed to the bulkhead 10.
When the liner bag 9 is thus attached to the inside -~
of the dry container 1, goods are charged from the charging port 31 to the inside oif the bag main body 11. Then, the goods can be loaded on the upper surface of the pull-out sheet 21. ``
In this case, impact shocks upon charging the goods ' ~^
force the sheet 21 toward the front side. However, since both lateral edges of the pull-out sheet 21 are provisionally secured in the bag main body 11 by means of provisional side securing means and, in addition, both lateral ends of the `~
pull-out sheet 21 drawn out of the opening 28 are secured completely to the bag main body 11 by means of the lower edge belt 17, as shown in Fig. 11, it is quite free from :`
such a trouble that the rear end of the pull-out sheet 21 ~ -",,, "~,,;j, - i -` 200;~57 : `
is dragged into the bag main body 11 and can not be pulled out upon discharging the goods.
In a case of unloading the goods charged in the bag main body 11, ~he rear ends Or the pull-out sheet 21 and the bottom face 11 on the side of the door 3 secured to the bulkhead 10 are released and they are unfolded flat as shown in Fig. 2. In this case, since the rear ends of the pull-out sheet 21 and the bottom portion lla are diæposed to the outer surface of the bulkhead 10, they can be unfolded flat with no troubles at all even when the goods exert a great pressure on the bulkhead 10.
Then, the rear end of the pull-out sheet 21 is wound around and secured to a take-up shaft of a discharging machine not illustrated and, thereafter, the lower support 47 of the bulkhead 10 is cut and removed by means of a knife, etc. This makes the lower-half of the bulkhead sheet 48 free, i.e., the lower portion of the bulkhead 10 is sub~tantially removed from the dry container 1. ~ ;~
Then, the lower portion of the rear face lld is cut `
open by a knife, etc. and the discharging machine is started to take-up the pull-out sheet 21 around the take-Up shaft. Thus, the pull-out sheet 21 is pulled toward the door 3 and the goods on the pull-out sheet 21 are transported toward the door 3 and discharged successively.
Now, upon stretching the pull-out sheet 21, both 2C)03;~57 lateral side edges thereor tend to gather toward the center and crease as the pull-out sheet 21 elongates. Thls ~ -tendency is particularly remarkable if the goods are loaded not evenly. Then, when the pull-out sheet 21 is drawn out in this state, a great amount Or goods may possibly be lert in the bag main body 11. --~
In this embodiment, however, since both lateral side edges Or the pull-out sheet 21 are provisionally secured `~
to the bag main body 11 by means Or a plurality Or velvet Pasteners 22, 23 disposed each at a predetermined interval along the pull-out direction, both Or the lateral sides Or the pull-out sheet 21 can be prevented rrom gathering toward the center. The rixing effect by the provisional side Pixing means is lost when they undergo a peeling or pulling force in excess Or a certain limit and the means ; . :: ' . !
i ~ are released one by one successively rrom those nearer to the door 3 each at a predetermined time delay. Accordingly, pulling rorce required for drawlng out the pull-out sheet ~-21 is substantially constant and not increased extremely instantaneously. ~ ~ ;
As the goods are discharged by nay Or the pull-out sheet 21 to some extent, the turned-back loop formed on - ~
the front side Or the pull-out sheet 21 is extended flat ~ ~ "
and, then, the V-shape portion 24 is pulled toward the ;~
;~ side Or the door 3.
. ~ . ; ,~
- 21 - ~- ;
By the way, since the provisional securing positions Or the V-shaped portion 24 to the rront race llc are dir-~erent between the lateral center and bo-th ends, provisional securing are released initially at the central portion and ~ -then at both ends. Accordingly, the V-shaped portion 24 is separated ~rom the ~ront face llc in a state as it is spread in the lateral direction and more goods can be discharged ;
by means Or the pull-out sheet 21.
When the primary discharging by means o~ the pull-out sheet 21 has thus been completed, both o~ the side faces llb and the front race llc are cut at a position slightly above the lower end by means Or a knire, etc., so that the bottom face lla is separated from other races llb, llc, . .,-, lld and lle of the bag main body 11.
Then, the rear end Or the bottom portion lla on the side of the door 3 is wound around and secured to the take-up shart of the discharging machine and the take-up shart is driven rotationally to pull the bottom race lla ~i toward the slde Or the door 3. Thus, the goods remained on the bottom race lla are also discharged.
Then, all Or the goods in the bag main body 11 can be ~, , .::
discharged automatically by the secondary discharge by means Or the bottom race lla.
In the roregoing embodiment, although the explanation has been made to a case in which the rear end Or the pull~
2003;~57 : ~ :
out sheet 21 on the side of the door 3 is contained between the bend piece 35 and the upper cover 36, the upper cover 36 may be saved. In addition, the core material 45 may also be saved optionally.
Further, in the foregoing embodiment, description has `~
been made to a case of using velvet ~asteners 22, 23, 25 and 26 as the provisionally rixing means for the side edge ;~
or the rront side, but other fixing means may also be used, such as both race adhesive tapes, hooks, yarns or tapes which are disconnected by an external pulling force greater than a predetermined level, as well as, clips. - ~ ~;

As has been described above, in the present invention, since the rear end Or the pull-out sheet 21 on the side Or the door 3 is previously drawn out Or the bag main body 11, the pull-out sheet 21 can be wound around and secured to the take-up shart Or the discharging machine berore opening the lower portion Or the rear race lld upon dis- ~ `~
charging the goods, thereby facilitating the unloading ~ `
,: ' ': ,: . -operation. Further, since the rear end of the bottom face lla on the side of the door 3 is also extended toward the side of the door 3, the goods can entirely be discharged ;~
automatically upon secondary discharge by means Or the bottom race lla. Further, since the rear ends oi~ the ,;
pull-out sheet 21 and the bottom race lla on the side the door 3 are secured to the outer surface Or the ;~

bulkhead 10, the bag main body 11 can be mounted with no ~ ~-trouble to the inside o~ a container such as the dry container 1 and handling for discharging the goods is also easy irrespective o~ the disposition Or the bulkhead 10. h-Further, since the rear end o~ the pull-out sheet 21 is secured to the outer surrace Or the bulkhead 10 being covered with the rear end Or the bottol~ race lla, it is ree ~rom contaminations, etc. ~`
Further, in the present invention, since the pulled out portion o~ the pull-out sheet 21 is secured to the ~ -bend piece 35 while being folded to the upper surrace Or the bend piece 35, operation Or securing to the outer surface Or the bulkhead 10 is easy.( : - , Further, in the present invention, since the upper ;~

oined at a position apart ~rom the rear race lld to the ~, side o~ the door 3 by a predetermined distance and the pulled out portion Or the pull-out sheet 21 is contained therebetween. Accordingly, even when the lower end of the rear ~ace lld is forced to protrude by the pressure ~rom the goods toward the side o~ the door 3, it is free ~rom such a trouble that the pull-out sheet 21 is caught under the rear race lld and can not be spread rlat. Further, since the pull-out sheet 21 is contained in a rolled state between the bend piece 35 and the upper cover 36, the upper surface Or the pull-out sheet 21 is not exposed externally and free rrom contarninations, etc. :~
Further, in the present invention, since -the retainer ,- :- .
belt 37 is disposed at the end Or the upper surface of the bend piece 35 on the side of the rear face lld, the lower end of the rear face lld can be prevented from being forced to protrude toward the side Or the door 3 though the~ -opening 28 is rormed to the lower end Or the rear face lld.
Further, in the present invention, since both Or the lateral side edges of the pull-out sheet 21 are secured each at an optional distance by means of provisional side securing means to the inner surface Or the bag main body 11 respectively, the pull-out sheet 21 can be prevented from displacement. Further, if the pull-out sheet 21 is pulled toward the side of the door 3, both lateral side edges thereof can erfectively be prevented from gathering ::: :~

relates to a liner bag capable of unloading such goods :
charged in a bag main body attached to the inside of a container easily and completely, without downwardly slanting the container toward to side of a container's door. ~
When transporting grain cargoes such as granular or ~ -powdery goods ~hereinafter simply referred to as goods) by using a dry container, etc., a bag main body has been attached usually to the inside of a container and the goods ~ ;-are charged in the bag main body. The present applicants ~; have previously proposed such a kind of liner bag in, for example, Japanese Utility Model Laid-Open No. Sho 61-45392, March 26, 1986. ~;
.,~
., ~ . .
~ By the way, in the liner bag of this kind, it is ;~
.~ ~
; necessary to slant the container downwardly toward the side : . ,~' , of a container's door upon unloading or discharging goods.
However, in a case of a large and long container such as a 40 feet~jlength container, there has been a proble~ that the. ~ -~
5, ~-~25 ~
~ ..
container can not be slanted easily, or the container can not be slanted to a required angle if the height of ceiling is low.
In view of the above, the present applicants have previously proposed a liner bag used for a container as disclosed in, for example, Japanese Utility Model Laid-Open Hei 1-107596, July 20, 1989, in which a draw sheet or a pull-out sheet is disposed at the inside of a bag main body, so `` `
that flowable goods can be unloaded by merely drawing or pulling out the pull-out sheet toward a container's door ~ without slanting the container. i~
`~ In our proposed liner bag having the pull-out sheet as described above, a rear end of a bottom face (on the side of " ~
the door) of the bag main body is extended toward the side of ~ '''' ~ "'`'t'~' the door beyond the rear face of the bag and a rear end of the pull-out sheet ~on the side of the door) is extended out of the bag main body through an opening formed in the lower ~ `~
end of the front face. Both of the extended portion of the `~
bag and the pulled-out portion of the sheet are folded back and disposed to the outer surface in the lower portion of the front face of the bag main body.
By the way, in a liner bag of a structure that the ` ` -outer side of the front face is supported by bulkhead detachably provided to one end of a container on the side of its door, there has been a problem that the extended portion of the bag main body and the pulled-out portion of the pull- ~ -S out sheet may hinder the mounting of the bulkhead or hinder the smooth operation of discharging goods.
Further, in a liner bag having the pull-out sheet, since a bag main body and a pull-out sheet are constituted separately, the pull-out sheet may, undesirably, be displaced from the bottom face of the bag main body when the latter folded before used is spread and attached to the inside of ;~ the container. Further, when the goods are charged into the -~
bag main body attached to the inside of the container, the pull-out sheet may possibly be displaced by impact shocks upon charging the goods.
Furthermore, when the pull-out sheet is drawn or pulled out toward the door of the container for unloading the goods there may be risk, if the goods are not loaded evenly, the I both side edges of the pull-out sheet are gathered toward the inside, failing to discharge the goods completely.
The present invention provides a liner bag used for a container capable ~; - 3 - ~ -,, ~ .
of attaching a bag main body easily to the inside of the container even when a bulkhead is used therein and also capable of facili~ating the operation of unloading goods.
The present invention also provides a liner bag used for ~ ;
a container capable of preventing the lower end of a rear `
face of the liner bag from protruding toward the side of a container's door by a pressure exerted from goods.even in a structure that an opening for pulling-out a rear end of a pull-out sheet from a bag main body is formed in the lower end of a rear face of the bag.
Further, the present invention provides a liner bag used for a container capable of completely preventing the pull-out sheet from being displaced when a folded bag main body is `
lS spread and attached to the inside of the container or when goods are charged to the inside of the bag main body, as well as capable of preventing both side edges of the pull-out sheet from gathering toward the inside and being creased upon pulling the pull-out sheet to the side of the door even if the goods are not loaded evenly.

a main body for lining the inside of said container and comprising a bottom face, a pair of side faces, a front face ``
and a rear face and wherein, when the liner bag is positioned ~.
within the container, said bottom face is opposed at least to ^~ a bottom wall of the container, said side faces are opposed ¦; to respective side walls of the container, said front face is ;

an extended portion of the rear end of the bottom face of said bag main body, said extended portion extending beyond -the position of the rear face in a direction towards the door, when the liner bag is positioned within the.container, wherein the extended portion of said bottom face is made foldabIe, and wherein the rear end of said pull-out sheet is ~ ;
pulled out of said bag main body through an opening formed in `
the lower end of the rear face of said bag main body and the pulled out portion of said pull-out sheet is made foldàble independently of the extended portion of said bottom ~ace;

means for securing the folded extended portion of the bottom face of the bag main body, together with the folded pulled-out portion of said sheet, to the surface of a bulkhead device detachably mounted to the rear end of said container, the arrangement being such that the latter portion is situated inside the former portion.
In the present invention, since the pulled-out portion of the pull-out sheet and the extended portion of the bottom ~ ;
face are folded independent of each other and secured together to the surface of the bulkhead device on the side of ~ ;~
theldoor, the bag main body can be mounted easily to the inside of the container even in a case of using such bulkhead device and, in addition, handling upon discharging goods is ~ ~`
also easy. Further, since the extended portion of the bottom face and the pulled-out portion of the pull-out sheet are ~ secured together to the bulkhead device, with the latter i~; portion being situated inside the former portion, the pull-~ ~ 5 ~

OPERATION
'~ Operation of this embodiment having the foregoing constitution will be described.
Upon using the liner bag 9, the bag main body 11 is at first inserted into the dry container and the upper hooks 13 are engaged to the upper engaging metal fixtures 6 and ~ the lower hooks 18 are engaged to the lower engaging metal ;~ fixtures 5 respectively.
~; Then, the rear ends of the upper edge belts 12 (on the side of the door 3) are wound around and bound to the ,. ~ ' : .': ~'' -': ~ '' .: .' ~, ,, ', ' ' ' ~" ~' , , .' , 2003:~5~ ~ ~
upper engaging metal fixtures 8 and the rear ends Or -the ~ ;:
lower edge belt 17 (on the side Or the door 3) are wound -around and secured to the lower engaging metal fixtures 7.
Subsequently, both ends of the reta:Lner belt 37 are secured to the lower engaging metal rixtures 7 respectively. `~
Thus, the opening 28 below the lower end Or -the rear face lld is urged from above to prevent the goods charged in the bag main body 11 from leaking through the opening 28.
In addition, the lower end of the rear face lld is prevented ~rom being protruded outwardly toward the door 3 by the pressure from the goods though the opening 28 is disposed at the lower end Or the rear race lld.
Then, as shown in Fig. 12, the bulkhead 10 i8 mounted between the recessed grooves 4. In this case, the rear end of the pull-out sheet 21 and that Or the bottom face ;... ,.,~
lla are pulled out as shown in Fig. 5 below the bulkhead . :~
device 10 toward the side Or the door 3.
Then, as shown in Fig. 9, the rear end Or the bottom face lla i9 rolled and contained under the slippery sheet 20, while the rear end Or the pull-out sheet 21 is rolled with the core material 45 being inside and then contained between the bend piece 35 and the upper cover 36. Then, the strings 42 are bound to the ring belts 40 to fix the pull-out sheet 21 between the bend piece 35 and the upper , cover 36. In this case, since the pull-out sheet 21 is contained in its rolled state between the bend piece 35 and the upper cover 36, the upper surface of the sheet 21 is not exposed externally and thus free from contamination.
Further, since -the pull-out sheet 21 is secured in its rolled stake between the bend piece 35 and the upper cover 36, it can be secured easily along the outer surface Or the bulkhead device 10, while maintaining khe folded æhape. ~-~
Since the stitch line 39 inhibits the pull-out sheet 21 from rurther entering toward the rear face lld, if the binding Or the retainer belt 37 to the lower engaging metal 7 is loosened and the lower end o~ the rear ~ace lld protrudes outwardly, there i8 no trouble tha-t the pull-out . . :
sheet 21 is caught under the rear race lld and can not be -spread rlat as shown in Fig. 2.
~, , .
After the pull-out sheet 21 has been contained and secured between the bend piece 35 and the upper cover 36, the rolled portion Or the bottom face lla is once turned ,,i. , ;
below the slippery sheet 20. Specirically, as shown in Fig. 9, the left end of the bottom race lla i~ bent at a position near the right end Or the string 43 over the upper surrace Or the right end. Subsequently, the ætring 41 and the string 42 are bound to each other and the string 43 is bound to the ring belt 44. Thus, the rolled ends of the pull-out sheet 21 and the bottom face lla on the side Or the door 3 are integrally secured, wlth the ~ -~
~,, '.~; :' ';' - 18 - ~ ~ ~
;` 200~2S7 bottom race lla being underside.
Then, they are uprighted to the rear face of the bulkhead 10 and, as shown in Fig. 13, the strings 43 are bound to the ring belts 53 Or the bulkhead sheet 48. Thus, the rear end of the pull-out sheet 21 is secured to the - --;
bulkhead 10, with the outer surrace thereof being covered with the bottom face lla.
The tongue 33 at the lower edge Or the charging port `~
31 is wound around the upper end Or the bulkhead sheet 48 and then bound at the ring belts 34 with the s-trings 52, by which the tongue is fixed to the bulkhead 10.
When the liner bag 9 is thus attached to the inside -~
of the dry container 1, goods are charged from the charging port 31 to the inside oif the bag main body 11. Then, the goods can be loaded on the upper surface of the pull-out sheet 21. ``
In this case, impact shocks upon charging the goods ' ~^
force the sheet 21 toward the front side. However, since both lateral edges of the pull-out sheet 21 are provisionally secured in the bag main body 11 by means of provisional side securing means and, in addition, both lateral ends of the `~
pull-out sheet 21 drawn out of the opening 28 are secured completely to the bag main body 11 by means of the lower edge belt 17, as shown in Fig. 11, it is quite free from :`
such a trouble that the rear end of the pull-out sheet 21 ~ -",,, "~,,;j, - i -` 200;~57 : `
is dragged into the bag main body 11 and can not be pulled out upon discharging the goods.
In a case of unloading the goods charged in the bag main body 11, ~he rear ends Or the pull-out sheet 21 and the bottom face 11 on the side of the door 3 secured to the bulkhead 10 are released and they are unfolded flat as shown in Fig. 2. In this case, since the rear ends of the pull-out sheet 21 and the bottom portion lla are diæposed to the outer surface of the bulkhead 10, they can be unfolded flat with no troubles at all even when the goods exert a great pressure on the bulkhead 10.
Then, the rear end of the pull-out sheet 21 is wound around and secured to a take-up shaft of a discharging machine not illustrated and, thereafter, the lower support 47 of the bulkhead 10 is cut and removed by means of a knife, etc. This makes the lower-half of the bulkhead sheet 48 free, i.e., the lower portion of the bulkhead 10 is sub~tantially removed from the dry container 1. ~ ;~
Then, the lower portion of the rear face lld is cut `
open by a knife, etc. and the discharging machine is started to take-up the pull-out sheet 21 around the take-Up shaft. Thus, the pull-out sheet 21 is pulled toward the door 3 and the goods on the pull-out sheet 21 are transported toward the door 3 and discharged successively.
Now, upon stretching the pull-out sheet 21, both 2C)03;~57 lateral side edges thereor tend to gather toward the center and crease as the pull-out sheet 21 elongates. Thls ~ -tendency is particularly remarkable if the goods are loaded not evenly. Then, when the pull-out sheet 21 is drawn out in this state, a great amount Or goods may possibly be lert in the bag main body 11. --~
In this embodiment, however, since both lateral side edges Or the pull-out sheet 21 are provisionally secured `~
to the bag main body 11 by means Or a plurality Or velvet Pasteners 22, 23 disposed each at a predetermined interval along the pull-out direction, both Or the lateral sides Or the pull-out sheet 21 can be prevented rrom gathering toward the center. The rixing effect by the provisional side Pixing means is lost when they undergo a peeling or pulling force in excess Or a certain limit and the means ; . :: ' . !
i ~ are released one by one successively rrom those nearer to the door 3 each at a predetermined time delay. Accordingly, pulling rorce required for drawlng out the pull-out sheet ~-21 is substantially constant and not increased extremely instantaneously. ~ ~ ;
As the goods are discharged by nay Or the pull-out sheet 21 to some extent, the turned-back loop formed on - ~
the front side Or the pull-out sheet 21 is extended flat ~ ~ "
and, then, the V-shape portion 24 is pulled toward the ;~
;~ side Or the door 3.
. ~ . ; ,~
- 21 - ~- ;
By the way, since the provisional securing positions Or the V-shaped portion 24 to the rront race llc are dir-~erent between the lateral center and bo-th ends, provisional securing are released initially at the central portion and ~ -then at both ends. Accordingly, the V-shaped portion 24 is separated ~rom the ~ront face llc in a state as it is spread in the lateral direction and more goods can be discharged ;
by means Or the pull-out sheet 21.
When the primary discharging by means o~ the pull-out sheet 21 has thus been completed, both o~ the side faces llb and the front race llc are cut at a position slightly above the lower end by means Or a knire, etc., so that the bottom face lla is separated from other races llb, llc, . .,-, lld and lle of the bag main body 11.
Then, the rear end Or the bottom portion lla on the side of the door 3 is wound around and secured to the take-up shart of the discharging machine and the take-up shart is driven rotationally to pull the bottom race lla ~i toward the slde Or the door 3. Thus, the goods remained on the bottom race lla are also discharged.
Then, all Or the goods in the bag main body 11 can be ~, , .::
discharged automatically by the secondary discharge by means Or the bottom race lla.
In the roregoing embodiment, although the explanation has been made to a case in which the rear end Or the pull~
2003;~57 : ~ :
out sheet 21 on the side of the door 3 is contained between the bend piece 35 and the upper cover 36, the upper cover 36 may be saved. In addition, the core material 45 may also be saved optionally.
Further, in the foregoing embodiment, description has `~
been made to a case of using velvet ~asteners 22, 23, 25 and 26 as the provisionally rixing means for the side edge ;~
or the rront side, but other fixing means may also be used, such as both race adhesive tapes, hooks, yarns or tapes which are disconnected by an external pulling force greater than a predetermined level, as well as, clips. - ~ ~;
.. .. ..
As has been described above, in the present invention, since the rear end Or the pull-out sheet 21 on the side Or the door 3 is previously drawn out Or the bag main body 11, the pull-out sheet 21 can be wound around and secured to the take-up shart Or the discharging machine berore opening the lower portion Or the rear race lld upon dis- ~ `~
charging the goods, thereby facilitating the unloading ~ `
,: ' ': ,: . -operation. Further, since the rear end of the bottom face lla on the side of the door 3 is also extended toward the side of the door 3, the goods can entirely be discharged ;~
automatically upon secondary discharge by means Or the bottom race lla. Further, since the rear ends oi~ the ,;
pull-out sheet 21 and the bottom race lla on the side the door 3 are secured to the outer surface Or the ;~

bulkhead 10, the bag main body 11 can be mounted with no ~ ~-trouble to the inside o~ a container such as the dry container 1 and handling for discharging the goods is also easy irrespective o~ the disposition Or the bulkhead 10. h-Further, since the rear end o~ the pull-out sheet 21 is secured to the outer surrace Or the bulkhead 10 being covered with the rear end Or the bottol~ race lla, it is ree ~rom contaminations, etc. ~`
Further, in the present invention, since the pulled out portion o~ the pull-out sheet 21 is secured to the ~ -bend piece 35 while being folded to the upper surrace Or the bend piece 35, operation Or securing to the outer surface Or the bulkhead 10 is easy.( : - , Further, in the present invention, since the upper ;~
, cover 36 is disposed above the bend piece 35, and they are `
oined at a position apart ~rom the rear race lld to the ~, side o~ the door 3 by a predetermined distance and the pulled out portion Or the pull-out sheet 21 is contained therebetween. Accordingly, even when the lower end of the rear ~ace lld is forced to protrude by the pressure ~rom the goods toward the side o~ the door 3, it is free ~rom such a trouble that the pull-out sheet 21 is caught under the rear race lld and can not be spread rlat. Further, since the pull-out sheet 21 is contained in a rolled state between the bend piece 35 and the upper cover 36, the upper surface Or the pull-out sheet 21 is not exposed externally and free rrom contarninations, etc. :~
Further, in the present invention, since -the retainer ,- :- .
belt 37 is disposed at the end Or the upper surface of the bend piece 35 on the side of the rear face lld, the lower end of the rear face lld can be prevented from being forced to protrude toward the side Or the door 3 though the~ -opening 28 is rormed to the lower end Or the rear face lld.
Further, in the present invention, since both Or the lateral side edges of the pull-out sheet 21 are secured each at an optional distance by means of provisional side securing means to the inner surface Or the bag main body 11 respectively, the pull-out sheet 21 can be prevented from displacement. Further, if the pull-out sheet 21 is pulled toward the side of the door 3, both lateral side edges thereof can erfectively be prevented from gathering ::: :~
toward the center and being creased. .~ .
Further, in the present invention, since the rront ~ .;
