Definitions
- the present invention relates to an encapsulating sheet container, and more particularly to an encapsulating sheet container which contains an encapsulating sheet.
- an encapsulating sheet including a resin film and a release sheet temporarily attached to a surface of the resin film is known (see, e.g., Patent Document 1 shown below).
- the release sheet is peeled from the resin film to expose the resin film.
- the encapsulating sheet is used by being stuck to an electronic element or the like to encapsulate the electronic element or the like.
- Patent Document 1 Japanese Unexamined Patent No. 2009-0141020
- the encapsulating sheet described in Patent Document 1 mentioned above has a problem in that, when a highly tacky resin is used for the resin film, the release sheet cannot be temporarily attached to the resin film, and the resin film cannot be protected.
- An encapsulating sheet container of the present invention is capable of containing an encapsulating sheet and includes a center portion having a predetermined thickness and extending along a first direction perpendicular to a thickness direction, a pair of end portions disposed on both external sides of the center portion in the first direction so as to be spaced apart from the center portion in the thickness direction, and a pair of connecting portions connecting the center portion and the pair of end portions along the thickness direction.
- Each of the pair of connecting portions includes at least one projecting portion which projects outwardly in the first direction, and at least one recessed portion which is recessed inwardly in the first direction.
- Two of the encapsulating sheet containers can selectively be stacked in a containing position or a stacking position in the thickness direction.
- the projecting portion of the encapsulating sheet container located on one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction
- the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction
- the pairs of connecting portions are positioned so as to be aligned in the thickness direction to bring the center portion of the encapsulating sheet container located on the one side in the thickness direction relatively away from the center portion of the encapsulating sheet container located on the other side in the thickness direction and thus form a space capable of containing the encapsulating sheet.
- the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction
- the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction
- the pairs of connecting portions are positioned so as to be arranged in the first direction to bring the center portion of the encapsulating sheet container located on the one side in the thickness direction relatively closer to the center portion of the encapsulating sheet container located on the other side in the thickness direction and thus result in a stacking length of the two encapsulating sheet containers which is shorter than in the containing position.
- the respective pairs of connecting portions of the two encapsulating sheet containers are positioned so as to be aligned in the thickness direction to bring the respective center portions of the two encapsulating sheet containers relatively away from each other. As a result, the space capable of containing the encapsulating sheet is formed.
- the respective pairs of connecting portions of the two encapsulating sheet containers are positioned so as to be arranged in the first direction to bring the respective center portions of the two encapsulating sheet containers relatively closer to each other. As a result, the stacking length of the two encapsulating sheet containers is shorter than in the containing position.
- the containing position in which the space capable of containing the encapsulating sheet is formed and the stacking position in which the stacking length of the two encapsulating sheet containers is shorter than in the containing position can be configured.
- the encapsulating sheet By thus stacking the two encapsulating sheet containers, in the containing position, the encapsulating sheet can be contained/protected in the space capable of containing the encapsulating sheet. In the stacking position, there is no need to store the encapsulating sheet and therefore it is possible to shorten the stacking length of the two encapsulating sheet containers and save space.
- the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction
- the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction.
- the end portion of the projecting portion of the encapsulating sheet container located on the one side in the thickness direction which is located on the other side in the thickness direction is out of contact with the end portion of the recessed portion of the encapsulating sheet container located on the other side in the thickness direction which is located on the one side in the thickness direction, while the end portion of the recessed portion of the encapsulating sheet container located on the one side in the thickness direction which is located on the other side in the thickness direction is in contact with the end portion of the projecting portion of the encapsulating sheet container located on the other side in the thickness direction which is located on the one side in the thickness direction.
- a fixation sheet for fixing the encapsulating sheet may be used.
- the fixation sheet is disposed so as to overlap the recessed portion and the projecting portion of the encapsulating sheet container located on the other side in the thickness direction when projected in the thickness direction.
- the pair of connecting portions are formed line-symmetrically relative to an imaginary line along a second direction which is perpendicular to both of the thickness direction and the first direction at a middle between the pair of connecting portions.
- each of such encapsulating sheet containers the pair of connecting portions are formed line-symmetrically relative to the imaginary line.
- the pair of connecting portions can be formed into identical shapes.
- a plurality of the recessed portions and a plurality of the projecting portions are formed to form a waveform shape along a second direction which is perpendicular to both of the thickness direction and the first direction.
- the plurality of recessed portions of the encapsulating sheet container located on the one side in the thickness direction and the plurality of projecting portions of the encapsulating sheet container located on the other side in the thickness direction are positioned so as to overlap each other.
- each of the encapsulating sheet containers is provided with the plurality of projecting portions and the plurality of recessed portions, in the case where the two encapsulating sheet containers are stacked in the stacking position, the respective projecting portions of the two encapsulating sheet containers are positioned so as to overlap each other and the respective recessed portions of the two encapsulating sheet containers are positioned so as to overlap each other when projected in the first direction.
- the respective pairs of connecting portions of the two encapsulating sheet containers can be positioned so as to be arranged in the first direction. This can shorten the stacking length of the two encapsulating sheet containers.
- the encapsulating sheet container of the present invention further includes positioning portions for positioning the two encapsulating sheet containers when the two encapsulating sheet containers are stacked, the positioning portions being provided on both external sides of the pair of end portions in the first direction.
- the positioning portions are used. This allows reliable positioning to be performed such that, in the containing position, when projected in the thickness direction, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction and the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction.
- the use of the positioning portions also allows reliable positioning to be performed such that, in the stacking position, when projected in the first direction, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction and the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction.

Abstract
Two encapsulating sheet containers can selectively be stacked in a containing position or a stacking position in a thickness direction. In the containing position, a center portion of the encapsulating sheet container located on one side in the thickness direction is brought relatively away from a center portion of the encapsulating sheet container located on the other side in the thickness direction. In the stacking position, the center portion of the encapsulating sheet container located on the one side in the thickness direction is brought relatively closer to the center portion of the encapsulating sheet container located on the other side in the thickness direction.
Description
- The present invention relates to an encapsulating sheet container, and more particularly to an encapsulating sheet container which contains an encapsulating sheet.
- It has conventionally been known to encapsulate an electronic element or the like with an encapsulating sheet and constitute an electronic device.
- As such an encapsulating sheet, an encapsulating sheet including a resin film and a release sheet temporarily attached to a surface of the resin film is known (see, e.g.,
Patent Document 1 shown below). - When such an encapsulating sheet is shipped, a surface of a resin film is protected by a release sheet.
- When the encapsulating sheet is used, the release sheet is peeled from the resin film to expose the resin film. The encapsulating sheet is used by being stuck to an electronic element or the like to encapsulate the electronic element or the like.
- Patent Document 1: Japanese Unexamined Patent No. 2009-0141020
- However, the encapsulating sheet described in
Patent Document 1 mentioned above has a problem in that, when a highly tacky resin is used for the resin film, the release sheet cannot be temporarily attached to the resin film, and the resin film cannot be protected. - When a surface of the resin film is not protected, a problem arises in that the resin film no longer serves as the encapsulating sheet as a result of contact with dust in air or another member.
- For the protection of the encapsulating sheet, it is examined to store the encapsulating sheet in a dedicated packing container having a space for preventing contact between the resin film and another member. However, in such a dedicated packing container, it is necessary to form the space in which the encapsulating sheet is contained. Accordingly, when such dedicated packing containers in which no encapsulating sheet is contained are stacked to be stored, shipped, and transported, the stacked packing containers become more bulky and need a larger space.
- It is therefore an object of the present invention to provide an encapsulating sheet container which can contain an encapsulating sheet with a simple configuration and save space when no encapsulating sheet is contained therein.
- An encapsulating sheet container of the present invention is capable of containing an encapsulating sheet and includes a center portion having a predetermined thickness and extending along a first direction perpendicular to a thickness direction, a pair of end portions disposed on both external sides of the center portion in the first direction so as to be spaced apart from the center portion in the thickness direction, and a pair of connecting portions connecting the center portion and the pair of end portions along the thickness direction. Each of the pair of connecting portions includes at least one projecting portion which projects outwardly in the first direction, and at least one recessed portion which is recessed inwardly in the first direction. Two of the encapsulating sheet containers can selectively be stacked in a containing position or a stacking position in the thickness direction. In the containing position, when projected in the thickness direction, the projecting portion of the encapsulating sheet container located on one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction, the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction, and the pairs of connecting portions are positioned so as to be aligned in the thickness direction to bring the center portion of the encapsulating sheet container located on the one side in the thickness direction relatively away from the center portion of the encapsulating sheet container located on the other side in the thickness direction and thus form a space capable of containing the encapsulating sheet. In the stacking position, when projected in the first direction, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction, the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction, and the pairs of connecting portions are positioned so as to be arranged in the first direction to bring the center portion of the encapsulating sheet container located on the one side in the thickness direction relatively closer to the center portion of the encapsulating sheet container located on the other side in the thickness direction and thus result in a stacking length of the two encapsulating sheet containers which is shorter than in the containing position.
- When two of such encapsulating sheet containers are stacked in the containing position, the respective pairs of connecting portions of the two encapsulating sheet containers are positioned so as to be aligned in the thickness direction to bring the respective center portions of the two encapsulating sheet containers relatively away from each other. As a result, the space capable of containing the encapsulating sheet is formed. On the other hand, when the two encapsulating sheet containers are stacked in the stacking position, the respective pairs of connecting portions of the two encapsulating sheet containers are positioned so as to be arranged in the first direction to bring the respective center portions of the two encapsulating sheet containers relatively closer to each other. As a result, the stacking length of the two encapsulating sheet containers is shorter than in the containing position.
- That is, from the two encapsulating sheet containers, the containing position in which the space capable of containing the encapsulating sheet is formed and the stacking position in which the stacking length of the two encapsulating sheet containers is shorter than in the containing position can be configured.
- By thus stacking the two encapsulating sheet containers, in the containing position, the encapsulating sheet can be contained/protected in the space capable of containing the encapsulating sheet. In the stacking position, there is no need to store the encapsulating sheet and therefore it is possible to shorten the stacking length of the two encapsulating sheet containers and save space.
- Also, in the containing position, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction, and the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction. In other words, the end portion of the projecting portion of the encapsulating sheet container located on the one side in the thickness direction which is located on the other side in the thickness direction is out of contact with the end portion of the recessed portion of the encapsulating sheet container located on the other side in the thickness direction which is located on the one side in the thickness direction, while the end portion of the recessed portion of the encapsulating sheet container located on the one side in the thickness direction which is located on the other side in the thickness direction is in contact with the end portion of the projecting portion of the encapsulating sheet container located on the other side in the thickness direction which is located on the one side in the thickness direction.
- For example, when the encapsulating sheet is placed in the space capable of containing the encapsulating sheet in the containing position, a fixation sheet for fixing the encapsulating sheet may be used.
- In such a case, the fixation sheet is disposed so as to overlap the recessed portion and the projecting portion of the encapsulating sheet container located on the other side in the thickness direction when projected in the thickness direction. As a result, it is possible to allow a part of the fixation sheet to be held between the recessed portion of the encapsulating sheet container located on the one side in the thickness direction and the projecting portion of the encapsulating sheet container located on the other side in the thickness direction and fixed.
- This allows the fixation sheet to be fixed using the recessed portion and the projecting portion of the pair of connecting portions for forming the space and allows the encapsulating sheet to be more efficiently contained in the encapsulating sheet container.
- In the encapsulating sheet container of the present invention, it is preferable that, when projected in the thickness direction, the pair of connecting portions are formed line-symmetrically relative to an imaginary line along a second direction which is perpendicular to both of the thickness direction and the first direction at a middle between the pair of connecting portions.
- In each of such encapsulating sheet containers, the pair of connecting portions are formed line-symmetrically relative to the imaginary line. By thus merely disposing either one of the encapsulating sheet container located on the one side in the thickness direction and the encapsulating sheet container located on the other side in the thickness direction such that one and the other of the pair of connecting portions of the encapsulating sheet containers are interchanged, it is possible to switch the two encapsulating sheet containers between the containing position and the stacking position.
- This allows the encapsulating sheet containers to be selectively stacked in the containing position or the stacking position by a simple operation.
- In addition, by forming the pair of connecting portions line-symmetrically relative to the imaginary line, the pair of connecting portions can be formed into identical shapes.
- In the encapsulating sheet container of the present invention, it is preferable that, in each of the pair of connecting portions, a plurality of the recessed portions and a plurality of the projecting portions are formed to form a waveform shape along a second direction which is perpendicular to both of the thickness direction and the first direction.
- In the case where such two encapsulating sheet containers are stacked in the containing position, when projected in the thickness direction, the plurality of recessed portions of the encapsulating sheet container located on the one side in the thickness direction and the plurality of projecting portions of the encapsulating sheet container located on the other side in the thickness direction are positioned so as to overlap each other.
- This allows the two encapsulating sheet containers to be stacked so as to have a plurality of portions in contact with each other. Therefore, it is possible to stably form the space capable of containing the encapsulating sheet using the two encapsulating sheet containers.
- Even though each of the encapsulating sheet containers is provided with the plurality of projecting portions and the plurality of recessed portions, in the case where the two encapsulating sheet containers are stacked in the stacking position, the respective projecting portions of the two encapsulating sheet containers are positioned so as to overlap each other and the respective recessed portions of the two encapsulating sheet containers are positioned so as to overlap each other when projected in the first direction.
- Accordingly, irrespective of the numbers of the projecting portions and the recessed portions, the respective pairs of connecting portions of the two encapsulating sheet containers can be positioned so as to be arranged in the first direction. This can shorten the stacking length of the two encapsulating sheet containers.
- As a result, when the two encapsulating sheet containers are stacked in the containing position, it is possible to stably form the space in which the encapsulating sheet is contained. On the other hand, when the two encapsulating sheet containers are stacked in the stacking position, it is possible to retain the short stacking length of the two encapsulating sheet containers when the encapsulating sheet is not contained.
- This allows the quality of the encapsulating sheet to be reliably retained.
- It is preferable that the encapsulating sheet container of the present invention further includes positioning portions for positioning the two encapsulating sheet containers when the two encapsulating sheet containers are stacked, the positioning portions being provided on both external sides of the pair of end portions in the first direction.
- When such two encapsulating sheet containers are stacked, the positioning portions are used. This allows reliable positioning to be performed such that, in the containing position, when projected in the thickness direction, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction and the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction.
- The use of the positioning portions also allows reliable positioning to be performed such that, in the stacking position, when projected in the first direction, the projecting portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the projecting portion of the encapsulating sheet container located on the other side in the thickness direction and the recessed portion of the encapsulating sheet container located on the one side in the thickness direction overlaps the recessed portion of the encapsulating sheet container located on the other side in the thickness direction.
- As a result, it is possible to stably stack the two encapsulating sheet containers in each of the containing position and the stacking position
- The encapsulating sheet container of the present invention can contain an encapsulating sheet with a simple configuration and save space when no encapsulating sheet is contained therein.

FIG. 1 , two encapsulatingsheet containers 1 in an embodiment of the present invention are stacked to contain an encapsulating sheet 96 (described later). Each of the encapsulatingsheet containers 1 is formed of a resin such as, e.g., a polyester-based resin such as polyethylene terephthalate (PET) or a polyolefin-based resin such as polyethylene (PE) or polystyrene (PS) into a generally rectangular thin plate shape in plan view having a given thickness (of, e.g., 0.3 to 1.0 mm). - Note that, when directions are mentioned with regard to the encapsulating
sheet containers 1, the directions are based on directions when each of the encapsulatingsheet containers 1 is placed in a horizontal direction. Specifically, the directions are based on the arrow directions shown in each of the drawings. It is assumed that the arrow directions shown inFIG. 1 are applied to the encapsulatingsheet container 1 shown on the lower part of the paper sheet withFIG. 1 . The following will describe the lowerencapsulating sheet container 1 in detail. - The encapsulating
sheet container 1 integrally includes a containingportion 4, aframe portion 5, agroove portion 6, and a plurality of (four)bridge portions 7. - As shown in
FIGS. 2 and 3 , the containingportion 4 is an inner portion of the encapsulatingsheet container 1 and formed into a generally boxy shape having an open lower end. - As shown in
FIGS. 1 and 3 , theframe portion 5 is the peripheral edge portion of the encapsulatingsheet container 1. Theframe portion 5 is formed in a generally rectangular frame shape in plan view disposed to be outwardly spaced apart from the outer peripheral edge of the containingportion 4 in each of a front-rear direction and a left-right direction and protrude upwardly. Theframe portion 5 is disposed such that the lower end portion thereof is at generally the same position as that of the lower end portion (lower end portions of a pair of first connectingwalls 11 and a pair of second connectingwalls 12 each described later) of the containingportion 4 in the upper-lower direction (thickness direction). Theframe portion 5 is also disposed such that the upper end portion thereof is located above the upper end portion (ceiling wall 10 described later) of the containingportion 4. - The
groove portion 6 is formed in a generally rectangular frame shape in plan view connecting the outer peripheral edge of the lower end of the containingportion 4 and the inner peripheral edge of the lower end of theframe portion 5. - As shown in
FIGS. 1 and 2 , thebridge portions 7 are formed to project upwardly from the four individual corners of thegroove portion 6 in plan view and provide bridges between the four individual corners of the containingportion 4 and the four individual corners of theframe portion 5 adjacent to the four individual corners of the containingportion 4. Thebridge portions 7 are also disposed such that the upper end portions thereof are at generally the same positions as that of the upper end portion (ceiling wall 10 described later) of the containingportion 4 in the upper-lower direction. - (1) Containing Portion
- As shown in
FIGS. 2 and 3 , the containingportion 4 includes theceiling wall 10 as an example of a center portion, and the pair of first connecting walls 11 (left/right connecting walls) as an example of a pair of connecting portions. As shown inFIGS. 2 and 4 , the containingportion 4 also includes the pair of second connecting walls 12 (front/rear connecting walls) as an example of the pair of connecting portions. - The
ceiling wall 10 is an upper portion of the containingportion 4 and is formed in a generally rectangular flat plate shape in plan view which is long in the front-rear direction. - As shown in
FIGS. 2 and 3 , the pair of first connectingwalls 11 are formed in generally rectangular flat plate shapes in side view which are disposed to be spaced apart from each other in the left-right direction (i.e., in a first direction) and extend continuously downwardly from the both outer end edges of theceiling wall 10 in the left-right direction. That is, as shown inFIG. 2 , the left-side first connecting wall 11 (one of the pair of first connecting walls 11) is disposed so as to extend between the left-front-side bridge portion 7 and the left-rear-side bridge portion 7, while the right-side first connecting wall 11 (the other of the pair of first connecting walls 11) is disposed to extend between the right-front-side bridge portion 7 and the right-rear-side bridge portion 7. As shown inFIG. 3 , the pair of first connectingwalls 11 are formed so as to be slightly inclined inwardly in the left-right direction as the height thereof increases. As shown inFIG. 2 , each of the first connectingwalls 11 includes a firstshorter portion 15, a firstlonger portion 16, a plurality of (six) first projecting portions 17 (containing-portion-side left-right projecting portions) as an example of a projecting portion, and a plurality of (five) first recessed portions 19 (containing-portion-side left-right recessed portions) as an example of a recessed portion. - The first
shorter portion 15 is a front-side portion of each of the first connectingwalls 11 and is formed in a generally linear flat plate shape in plan view. - The first
longer portion 16 is a rear-side portion of each of the first connectingwalls 11 and is formed in a generally linear flat plate shape in plan view. The length of the firstlonger portion 16 in the front-rear direction (i.e., a second direction) is longer than the length of the firstshorter portion 15 in the front-rear direction. - The six first projecting
portions 17 are equidistantly arranged along the front-rear direction between the firstshorter portion 15 and the firstlonger portion 16 in each of the first connectingwalls 11. Note that the frontmost first projectingportion 17 is continued to the firstshorter portion 15, while the rearmost first projectingportion 17 is continued to the firstlonger portion 16. As shown inFIGS. 1 and 2 , each of the first projectingportions 17 is formed in a generally semi-circular shape in plan view which projects outwardly in the left-right direction so as to be curved and extends over the entire range of the first connectingwall 11 in the upper-lower direction. As shown inFIG. 2 , the outer end portion of each of the first projectingportions 17 in the left-right direction is located to be external of each of the first shorter portion and the firstlonger portion 16 in the left-right direction. - The five first recessed
portions 19 are equidistantly arranged along the front-rear direction between the firstshorter portion 15 and the firstlonger portion 16 in each of the first connectingwalls 11. As shown inFIGS. 1 and 2 , each of the first recessedportions 19 is disposed continuously to and between the first projectingportions 17 adjacent to each other in the front-rear direction and formed in a generally semi-circular shape in plan view which is recessed inwardly in the left-right direction so as to be curved and extends over the entire range of the first connectingwall 11 in the upper-lower direction. As shown inFIG. 2 , each of the first recessedportions 19 is disposed such that the inner end portion thereof in the left-right direction is at generally the same position as that of each of the firstshorter portion 15 and the firstlonger portion 16 in the left-right direction. - Thus, in the end portions of each of the first connecting
walls 11 in the front-rear direction, the firstshorter portion 15 and the firstlonger portion 16 are formed and, continuously to and between the firstshorter portion 15 and the firstlonger portion 16, the plurality of first projectingportions 17 and the plurality of first recessedportions 19 are alternately formed. Consequently, the both outer end edges of theceiling wall 10 in the left-right direction are formed such that, in plan view, the both end portions thereof in the front-rear direction have generally linear shapes along the front-rear direction and generally middle portions thereof in the front-rear direction have waveform shapes along the front-rear direction. - When projected in the upper-lower direction, the generally-semi-circular portions of the
ceiling wall 10 which are surrounded by the first projectingportions 17 are defined as first-projecting-portion upper surfaces 18. That is, the six first-projecting-portionupper surfaces 18 are defined along the front-rear direction in each of the outer portions of theceiling wall 10 in the left-right direction in correspondence to the plurality of first projectingportions 17. - Thus, in the containing
portion 4, the pair of first connectingwalls 11 are formed line-asymmetrically relative to an imaginary line X (see the imaginary lines inFIG. 2 ) along the left-right direction at the middle between the pair of second connectingwalls 12 and line-symmetrically relative to an imaginary line Y (see the imaginary lines inFIG. 2 ) along the front-rear direction at the middle between the pair of first connectingwalls 11. - As shown in
FIGS. 2 and 4 , the pair of second connectingwalls 12 are formed in generally rectangular flat plate shapes in front view which are disposed to be spaced apart from each other in the front-rear direction and extend continuously downwardly from the both outer end edges of theceiling wall 10 in the front-rear direction. That is, as shown inFIG. 2 , the front-side second connecting wall 12 (one of the pair of second connecting walls 12) is disposed so as to extend between the left-front-side bridge portion 7 and the right-front-side bridge portion 7, while the rear-side second connecting wall 12 (the other of the pair of second connecting walls 12) is disposed so as to extend between the left-rear-side bridge portion 7 and the right-rear-side bridge portion 7. The length of each of the second connectingwalls 12 in the left-right direction is shorter than the length of each of the first connectingwalls 11 in the front-rear direction. As shown inFIG. 4 , the pair of second connectingwalls 12 are formed so as to be slightly inclined inwardly in the front-rear direction as the height thereof increases. As shown inFIG. 2 , each of the second connectingwalls 12 includes a secondshorter portion 25, a secondlonger portion 26, a plurality of (five) second recessed portions 29 (containing-portion-side front-rear recessed portions) as an example of the recessed portion, and a plurality of (four) second projecting portions 27 (containing-portion-side front-rear projecting portions) as an example of the projecting portion. - The second
shorter portion 25 is a left-side portion of each of the second connectingwalls 12 and is formed in a generally linear flat plate shape in plan view. - The second
longer portion 26 is a right-side portion of each of the second connectingwalls 12 and is formed in a generally linear flat plate shape in plan view. The length of the secondlonger portion 26 in the left-right direction is longer than the length of the secondshorter portion 25 in the left-right direction. - The five second recessed
portions 29 are equidistantly arranged along the left-right direction between the secondshorter portion 25 and the secondlonger portion 26 in each of the second connectingwalls 12. Note that the leftmost second recessedportion 29 is continued to the secondshorter portion 25, while the rightmost second recessedportion 29 is continued to the secondlonger portion 26. As shown inFIGS. 1 and 2 , each of the second recessedportions 29 is formed in a generally semi-circular shape in plan view which is recessed inwardly in the front-rear direction so as to be curved and extends over the entire range of the second connectingwall 12 in the upper-lower direction.

- The
bridge portions 7 are disposed at the four individual corners of the containingportion 4 so as to extend along the diagonal lines of the encapsulatingsheet container 1 and provide bridges between the containingportion 4 and theframe portion 5. Each of thebridge portions 7 is formed in a generally trapezoidal shape in cross-sectional view having an upwardly decreasing width. Thebridge portions 7 includereceptacle portions 80. - The
receptacle portions 80 are outer portions of thebridge portions 7 which are disposed so as to be adjacent to the four corners (connecting portions between the pair offirst positioning portions 32 and the pair of second positioning portions 33) of theframe portion 5 from inside the encapsulatingsheet container 1 and formed so as to be recessed downward into generally semi-circular shapes. - As shown in
FIG. 1 , thefixation sheet 93 is made of, e.g., polyethylene terephthalate (PET) and formed in a flexible thin plate shape having a given thickness (of, e.g., 0.02 to 0.20 mm) in the upper-lower direction and extending in each of the front-rear direction and the left-right direction. The lengths of thefixation sheet 93 in the front-rear direction and in the left-right direction are the same as the lengths of the fixationsheet mounting region 84 in the front-rear direction and in the left-right direction. - The
fixation sheet 93 is formed of a single-sided adhesive sheet having an upper surface with surface tack. To prevent thefixation sheet 93 from adhering to the encapsulatingsheet container 1 upon mere contact of the first-recessed-portionlower surfaces 73 and the second-recessed-portionlower surfaces 74 of the encapsulatingsheet container 1 with thefixation sheet 93 from above, the adhesive force of thefixation sheet 93 is set to a value in a range of, e.g., not less than 1 Pa, or preferably not less than 5 Pa and, e.g., not more than 100 Pa, or preferably not more than 50 Pa. Note that, when the adhesive force of thefixation sheet 93 is larger than 100 Pa, in the case where the encapsulatingsheet container 1 is upwardly lifted while the first-recessed-portionlower surfaces 73 and the second-recessed-portionlower surfaces 74 of the encapsulatingsheet container 1 are in contact with thefixation sheet 93, thefixation sheet 93 may be lifted together with the encapsulatingsheet container 1. When the adhesive force of thefixation sheet 93 is smaller than 1 Pa, it is difficult to fix thefixation sheet 93 with the encapsulating sheet container 1 (encapsulatingsheet container 1B described later) in a stacking position described later. As a result, the encapsulating sheet 96 (described later) may not be able to be stably shipped and transported. Preferably, the adhesive force of thefixation sheet 93 to the encapsulating sheet 96 (described later) is larger than the adhesive force of thefixation sheet 93 to the encapsulatingsheet container 1. - As shown in
FIG. 13A , the encapsulatingsheet 96 includes abase material 97 and anencapsulating layer 98. - The
base material 97 is made of a resin film or the like and formed in a generally rectangular thin plate shape in plan view which is long in the left-right direction and has a given thickness (of, e.g., 0.02 to 1.50 mm) in the upper-lower direction. - The encapsulating
layer 98 is made of a resin (adhesive) having adhesion and formed in a generally rectangular thin plate shape in plan view which is laminated on a generally middle portion of thebase material 97 in plan view. - Note that, in the encapsulating
sheet 96, the shape and size of thebase material 97 and the shape and size of theencapsulating layer 98 are not particularly limited. Each of thebase material 97 and theencapsulating layer 98 may have any shape as long as thebase material 97 is smaller than the encapsulatingsheet mounting region 85 and theencapsulating layer 98 is smaller than thebase material 97. For example, as shown inFIG. 13B , the encapsulatingsheet 96 may also be formed in a generally circular thin plate shape in plan view. Alternatively, the encapsulatingsheet 96 may also be formed in, e.g., a generally triangular thin plate shape in plan view, a generally L-shaped thin plate shape in plan view, a generally star-like thin plate shape in plan view, or the like, though not shown. - Two or more of the foregoing encapsulating
sheet containers 1 can be stacked in the upper-lower direction. As shown inFIG. 5 , the encapsulatingsheet containers 1 can selectively be stacked in a containing position in which the encapsulatingsheet 96 described above can be contained and the stacking position in which the encapsulatingsheet 96 is not contained. - In describing the stacking of the encapsulating
sheet containers 1, it is assumed that, inFIGS. 5 to 11 , the lowerencapsulating sheet container 1 is an encapsulatingsheet container 1A, each of the members belonging to the encapsulatingsheet container 1A has A at the end of its reference numeral, the upperencapsulating sheet container 1 is an encapsulatingsheet container 1B, and each of the members belonging to the encapsulatingsheet container 1B has B at the end of its reference numeral to distinguish the two encapsulatingsheet containers 1 from each other. - (1) Containing Position
- To stack the encapsulating
sheet containers 1 in the containing position in which the encapsulatingsheet container 96 can be contained, first, two of the encapsulatingsheet containers 1 having identical shapes, thefixation sheet 93, and the encapsulatingsheet 96 are prepared. - Then, as shown in
FIG. 6 , thefixation sheet 93 is placed on theceiling wall 10A of the encapsulatingsheet container 1A. - To place the
fixation sheet 93 on theceiling wall 10A, thefixation sheet 93 is placed from above such that the non-adhesive surface (lower surface) of thefixation sheet 93 is brought into contact with the fixationsheet mounting region 84A of theceiling wall 10A. Thus, thefixation sheet 93 is placed on the fixationsheet mounting region 84A of theceiling wall 10A. - Then, on the
fixation sheet 93, the encapsulatingsheet 96 is placed. - To place the encapsulating
sheet 96 on thefixation sheet 93, the encapsulatingsheet 96 is placed from above such that, within the encapsulatingsheet mounting region 85A of theceiling wall 10A, thebase member 97 of the encapsulatingsheet 96 is brought into contact with thefixation sheet 93. Thus, the encapsulatingsheet 96 is placed on the encapsulatingsheet mounting region 85A of theceiling wall 10A. - The method of placing the
fixation sheet 93 and the encapsulatingsheet 96 on theceiling wall 10A is not limited to the order shown above. It is also possible to place the encapsulatingsheet 96 on thefixation sheet 93 first, and then place thefixation sheet 93 on which the encapsulatingsheet 96 has been placed on theceiling wall 10A. - Note that, as shown in
FIG. 13 , a plurality of the encapsulatingsheets 96 of whatever shapes can be placed as long as the encapsulatingsheets 96 are contained in the encapsulatingsheet mounting region 85. - Next, as shown in
FIG. 5 , on the encapsulatingsheet container 1A on which thefixation sheet 93 and the encapsulatingsheet 96 have been placed, the encapsulatingsheet container 1B is stacked from above. - Specifically, as shown in
FIGS. 5 and 6 , the encapsulatingsheet container 1B is 180° rotated relative to the encapsulatingsheet container 1A around a middle point Z along the upper-lower direction extending through the point of intersection between the diagonal lines (not shown) of the encapsulatingsheet container 1 in plan view. That is, the encapsulatingsheet container 1B is disposed such that one and the other of the pair of the first connectingwalls 11B are interchanged relative to the imaginary line Y and one and the other of the pair of second connectingwalls 12B are interchanged relative to the imaginary line X. - Thus, the encapsulating
sheet container 1B is stacked on the encapsulatingsheet container 1A from above such that, when projected in the upper-lower direction, one of a pair of first connectingwalls 11A, one of a pair of second connectingwalls 12A, one of a pair offirst positioning portions 32A, and one of a pair ofsecond positioning portions 33A respectively correspond to the other of the pair of first connectingwalls 11B, the other of the pair of second connectingwalls 12B, the other of a pair offirst positioning portions 32B, and the other of a pair ofsecond positioning portions 33B. - As a result, as shown in
FIG. 6 , in plan view, the firstshorter portions 15A of the first connectingwalls 11A overlap the firstlonger portions 16B of the first connectingwalls 11B, and the firstlonger portions 16A of the first connectingwalls 11A overlap the firstshorter portions 15B of the first connectingwalls 11B. This causes the waveform shape including the first projectingportions 17A and the first recessedportions 19A in each of the first connectingwalls 11A to overlap the waveform shape including the first projectingportions 17B and the first recessedportions 19B in each of the first connectingwalls 11B in misaligned relation. That is, when projected in the upper-lower direction, the first projectingportions 17A overlap the first recessedportions 19B, and the first recessedportions 19A overlap the first projectingportions 17B. - Also, in plan view, the second
shorter portions 25A of the second connectingwalls 12A overlap the secondlonger portions 26B of the second connectingwalls 12B, and the secondlonger portions 26A of the second connectingwalls 12A overlap the secondshorter portions 25B of the second connectingwalls 12B. This causes the waveform shape including the second projectingportions 27A and the second recessedportions 29A in each of the second connectingwalls 12A to overlap the waveform shape including the second projectingportions 27B and the second recessedportions 29B in each of the second connectingwalls 12B in misaligned relation. That is, when projected in the upper-lower direction, the second projectingportions 27A overlap the second recessedportions 29B, and the second recessedportions 29A overlap the second projectingportions 27B. - Also, in plan view, the third
shorter portions 45A of the firstinner walls 37A overlap the thirdlonger portions 46B of the firstinner walls 37B, and the thirdlonger portions 46A of the firstinner walls 37A overlap the thirdshorter portion 45B of the firstinner walls 37B. This causes the waveform shape including the third projectingportions 47A and the third recessedportions 49A in each of the firstinner walls 37A to overlap the waveform shape including the third projectingportions 47B and the third recessedportions 49B in each of the firstinner walls 37B in misaligned relation. That is, when projected in the upper-lower direction, the third projectingportions 47A overlap the third recessedportions 49B, and the third recessedportions 49A overlap the third projectingportions 47B. - Also, in plan view, the fourth
shorter portions 55A of the secondinner walls 40A overlap the fourthlonger portions 56B of the secondinner walls 40B, and the fourthlonger portions 56A of the secondinner walls 40A overlap the fourthshorter portions 55B of the secondinner walls 40B. This causes the waveform shape including the fourth projectingportions 57A and the fourth recessedportions 59A in each of the secondinner walls 40A to overlap the waveform shape including the fourth projectingportions 57B and the fourth recessedportions 59B in each of the secondinner walls 40B in misaligned relation. That is, when projected in the upper-lower direction, the fourth projectingportions 57A overlap the fourth projectingportions 57B, and the fourth recessedportions 59A overlap the fourth recessedportions 59B. - As a result, as shown in
FIGS. 7 and 8 , the plurality of first-recessed-portionlower surfaces 73B of the encapsulatingsheet container 1B are brought into contact with the plurality of first-projecting-portionupper surfaces 18A of the encapsulatingsheet container 1A. The plurality of second-recessed-portionlower surfaces 74B of the encapsulatingsheet container 1B are brought into contact with the plurality of second-projecting-portionupper surfaces 28A of the encapsulatingsheet container 1A. The plurality of third-recessed-portionlower surfaces 76B of the encapsulatingsheet container 1B are brought into contact with the plurality of third-projecting-portionupper surfaces 48A of the encapsulatingsheet container 1A. The plurality of fourth-recessed-portionlower surfaces 77B of the encapsulatingsheet container 1B are brought into contact with the plurality of fourth-projecting-portionupper surfaces 58A of the encapsulatingsheet container 1A. That is, the first connectingwalls 11A and the first connectingwalls 11B are positioned so as to be aligned in the upper-lower direction, and the second connectingwalls 12A and the second connectingwalls 12B are positioned so as to be aligned in the upper-lower direction. This brings theceiling walls ceiling wall 10 and the containingportion 4B is defined as a containingspace 88. - The length of the containing
space 88 in the upper-lower direction, i.e., a length L1 between theceiling walls - As a result, the
fixation sheet 93 placed on the fixationsheet mounting region 84 has the both end portions thereof in the left-right direction held between the plurality of first-projecting-portionupper surfaces 18A and the plurality of first-recessed-portionlower surfaces 73B and has the both end portions thereof in the front-rear direction held between the plurality of second-projecting-portionupper surfaces 28A and the plurality of second-recessed-portionlower surfaces 74B to be fixed by the encapsulatingsheet containers fixation sheet 93 has been set to a level which prevents thefixation sheet 93 from following the first-recessed-portionlower surfaces 73B and the second-recessed-portionlower surfaces 74B even when the encapsulatingsheet container 1B is moved away from the encapsulatingsheet container 1A. Accordingly, there is no movement of thefixation sheet 93 from the fixationsheet mounting region 84. - In addition, a plurality of first large recessed
portions 52B of the encapsulatingsheet container 1B are brought into engagement with a plurality of first supportingportions 53A of the encapsulatingsheet container 1A. This brings the plurality of first supportedportions 64 into contact with the lower surfaces of the plurality of first supportingportions 53A. At the same time, a plurality of second large recessedportions 62B of the encapsulatingsheet container 1B are brought into engagement with a plurality of second supportingportions 63A of the encapsulatingsheet container 1A. This brings the plurality of second supportedportions 65 into contact with the lower surfaces of the plurality of second supportingportions 63A. - Such engagement of the
frame portion 5B with theframe portion 5A restricts the movement of the encapsulatingsheet container 1B relative to the encapsulatingsheet container 1A in each of the front-rear direction and the left-right direction. - Thus, the encapsulating
sheet container 1B is positioned relative to the encapsulatingsheet container 1A. - In this manner, the two encapsulating
sheet containers 1 are stacked in the containing position in which the encapsulatingsheet 96 can be contained. - Note that, as shown in
FIG. 12A , by stacking a plurality of the encapsulatingsheet containers 1 in the containing position, a large number of the encapsulatingsheets 96 can be contained. - (2) Stacking Position
- To stack the encapsulating
sheet containers 1 in the stacking position in which the encapsulatingsheet 96 is not contained, two of the encapsulatingsheet containers 1 having identical shapes are prepared. - Then, the encapsulating
sheet container 1B is stacked on the encapsulatingsheet container 1A from above. - Specifically, the encapsulating
sheet container 1B is assembled to the encapsulatingsheet container 1A from above such that one of the pair of first connectingwalls 11A, one of the pair of second connectingwalls 12A, the other of the pair offirst positioning portions 32A, and the other of the pair ofsecond positioning portions 33A respectively correspond to one of the pair of first connectingwalls 11B, one of the pair of second connectingwalls 12B, the other of the pair offirst positioning portions 32B, and the other of the pair ofsecond positioning portions 33B. - Consequently, as shown in
FIG. 10 , the pair of first connectingwalls 11B are brought into contact with the pair of first connectingwalls 11A so as to extend along the slopes of the pair of first connectingwalls 11A, and the pair offirst positioning portions 32B are brought into contact with the pair offirst positioning portions 32A so as to extend along the slopes of the pair offirst positioning portions 32A. On the other hand, as shown inFIG. 11 , the pair of second connectingwalls 12B are brought into contact with the pair of second connectingwalls 12A so as to extend along the slopes of the pair of second connectingwalls 12A, and the pair ofsecond positioning portions 33B are brought into contact with the pair ofsecond positioning portions 33A so as to extend along the slopes of the pair ofsecond positioning portions 33A. - Note that, at this time, when projected in the left-right direction, in the first connecting
walls portions portions first positioning portions portions portions - On the other hand, when projected in the front-rear direction, in the second connecting
walls portions portions second positioning portions portions portions - Also, the
ceiling wall 10A of the encapsulatingsheet container 1A and theceiling wall 10B of the encapsulatingsheet container 1B are brought relatively closer to each other. A distance L2 between theceiling walls - As a result, the stacking length of the two encapsulating
sheet containers 1 is shorter than in the containing position. - In this manner, the two encapsulating
sheet containers 1 are stacked in the stacking position in which the encapsulatingsheet 96 is not contained. - Note that, as shown in
FIG. 12B , by stacking a plurality of the encapsulatingsheet containers 1 in the stacking position, it is possible to save space when the plurality of encapsulatingsheet containers 1 are shipped/transported. - As shown in
FIG. 7 , when the two encapsulatingsheet containers 1 having identical shapes are stacked in the containing position, the respective pairs of first connectingwalls 11 of the two encapsulatingsheet containers 1 are positioned so as to be aligned in the upper-lower direction while, as shown inFIG. 8 , the respective pairs of second connectingwalls 12 of the two encapsulatingsheet containers 1 are positioned so as to be aligned in the upper-lower direction. This brings therespective ceiling walls 10 of the two encapsulatingsheet containers 1 relatively away from each other, resulting in the formation of the containingspace 88 capable of containing the encapsulatingsheet 96. On the other hand, as shown inFIG. 10 , when the two encapsulatingsheet containers 1 are stacked in the stacking position, the respective pairs of the first connectingwalls 11 of the two encapsulatingsheet containers 1 are positioned so as to be arranged in the left-right direction while, as shown inFIG. 11 , the respective pairs of the second connectingwalls 12 are positioned so as to be arranged in the front-rear direction. This brings therespective ceiling walls 10 of the two encapsulatingsheet containers 1 relatively closer to each other, resulting in the stacking length of the two encapsulatingsheet containers 1 which is shorter than in the containing position. - That is, from the two encapsulating
sheet containers 1, the containing position (seeFIG. 5 ) in which the containingspace 88 capable of containing the encapsulatingsheet 96 is formed and the stacking position (seeFIG. 9 ) in which the stacking length of the two encapsulatingsheet containers 1 is shorter than in the containing position can be configured. - By thus stacking the two encapsulating
sheet containers 1, in the containing position, as shown inFIG. 5 , the encapsulatingsheet 96 can be contained/protected in the containingspace 88 capable of containing the encapsulatingsheet 96. On the other hand, in the stacking position, as shown inFIG. 9 , the encapsulatingsheet 96 need not be contained and therefore it is possible to shorten the stacking length of the two encapsulatingsheet containers 1 and save space. - Also, in the containing position, as shown in
FIG. 7 , the first projectingportions 17B of the encapsulatingsheet container 1B overlap the first recessedportions 19A of the encapsulatingsheet container 1A, and the first recessedportions 19B of the encapsulatingsheet container 1B overlap the first projectingportions 17A of the encapsulatingsheet container 1A. In other words, the lower end portions of the first projectingportions 17B of the encapsulatingsheet container 1B are out of contact with the upper end portions of the first recessedportions 19A of the encapsulatingsheet container 1A, while the lower end portions (i.e., first-recessed-portionlower surfaces 73B) of the first recessedportions 19B of the encapsulatingsheet container 1B are brought into contact with the upper end portions (i.e., first-projecting-portionupper surfaces 18A) of the first projectingportions 17A of the encapsulatingsheet container 1A. Also, in the containing position, as shown inFIG. 8 , the second projectingportions 27B of the encapsulatingsheet container 1B overlap the second recessedportions 29A of the encapsulatingsheet container 1A, and the second recessedportions 29B of the encapsulatingsheet container 1B overlap the second projectingportions 27A of the encapsulatingsheet container 1A. In other words, the lower end portions of the second projectingportions 27B of the encapsulatingsheet container 1B are out of contact with the upper end portions of the second recessedportions 29A of the encapsulatingsheet container 1A, while the lower end portions (i.e., second-recessed-portionlower surfaces 74B) of the second recessedportions 29B of the encapsulatingsheet container 1B are brought into contact with the upper end portions (i.e., second-projecting-portionupper surfaces 28A) of the second projectingportions 27A of the encapsulatingsheet container 1A. - For example, when the encapsulating
sheet 96 is placed in the containingspace 88 capable of containing the encapsulatingsheet 96 in the containing position, thefixation sheet 93 for fixing the encapsulatingsheet 96 may be used. - In such a case, as shown in
FIG. 6 , thefixation sheet 93 is disposed so as to overlap the first recessedportions 19A and the first projectingportions 17A of the encapsulatingsheet container 1A when projected in the upper-lower direction. As a result, as shown inFIG. 7 , it is possible to allow a part of thefixation sheet 93 to be held between the first-recessed-portionlower surfaces 73B and the first-projecting-portionupper surfaces 18A and fixed. Thefixation sheet 93 is also disposed so as to overlap the second recessedportions 29A and the second projectingportions 27A of the firstencapsulating sheet container 1A when projected in the upper-lower direction. As a result, as shown inFIG. 8 , it is possible to allow a part of thefixation sheet 93 to be held between the second-recessed-portionlower surfaces 74B and the second-projecting-portionupper surfaces 28A and fixed. - This allows the
fixation sheet 93 to be fixed using the first recessedportions 19 and the first projectingportions 17 of the pair of first connectingwalls 11 and the second recessedportions 29 and the second projectingportions 27 of the pair of second connectingwalls 12, each for forming the containingspace 88, and allows the encapsulatingsheet 96 to be more efficiently contained in the encapsulatingsheet container 1. - In the encapsulating
sheet container 1, as shown inFIG. 2 , the pair of first connectingwalls 11 are formed line-symmetrically relative to the imaginary line Y, and the pair of second connectingwalls 12 are formed line-symmetrically relative to the imaginary line X. - As a result, as shown in
FIG. 6 , by merely disposing the encapsulatingsheet container 1B such that one and the other of the pair of first connectingwalls 11B of the encapsulatingsheet container 11B are interchanged relative to the imaginary line Y and one and the other of the pair of second connectingwalls 12B of the encapsulatingsheet container 11B are interchanged relative to the imaginary line X, it is possible to switch the encapsulatingsheet containers - This allows the encapsulating
sheet containers - In addition, by forming the pair of first connecting
walls 11 line-symmetrically relative to the imaginary line Y, the pair of first connectingwalls 11 can be formed into identical shapes and, by forming the pair of second connectingwalls 12 line-symmetrically relative to the imaginary line X, the pair of second connectingwalls 12 can be formed into identical shapes. - As shown in
FIG. 6 , in the case where the two encapsulatingsheet containers 1 having identical shapes are stacked in the containing position, when projected in the upper-lower direction, the plurality of first recessedportions 19B of the encapsulatingsheet container 1B and the plurality of first projectingportions 17A of the encapsulatingsheet container 1A are positioned so as to overlap each other, and the plurality of second recessedportions 29B of the encapsulatingsheet container 1B and the plurality of second projectingportions 27A of the encapsulatingsheet container 1A are positioned so as to overlap each other. - This allows the two encapsulating
sheet containers 1 to be stacked so as to have a plurality of portions in contact with each other. Therefore, it is possible to stably form the containingspace 88 capable of containing the encapsulatingsheet 96 using the two encapsulatingsheet containers 1. - Even though each of the encapsulating
sheet containers 1 is provided with the plurality of first projectingportions 17, the plurality of first recessedportions 19, the plurality of second projectingportions 27, and the plurality of second recessedportions 29, when the two encapsulatingsheet containers 1 are stacked in the stacking position, as shown inFIG. 10 , the respective first projectingportions 17 of the two encapsulatingsheet containers 1 are positioned so as to overlap each other and the respective first recessedportions 19 of the two encapsulatingsheet containers 1 are positioned so as to overlap each other when projected in the left-right direction. Also, as shown inFIG. 11 , the respective second projectingportions 27 of the two encapsulatingsheet container 1 are positioned so as to overlap each other and the respective second recessedportions 29 of the two encapsulatingsheet containers 1 are positioned to overlap each other when projected in the front-rear direction. - Accordingly, irrespective of the numbers of the first projecting
portions 17 and the first recessedportions 19 or the numbers of the second projectingportions 27 and the second recessedportions 29, the respective pairs of first connectingwalls 11 of the two encapsulatingsheet containers 1 can be positioned so as to be arranged in the left-right direction, and the respective pairs of second connectingwalls 12 of the two encapsulatingsheet containers 1 can be positioned so as to be arranged in the front-rear direction. This can shorten the stacking length of the two encapsulatingsheet containers 1. - As a result, when the two encapsulating
sheet containers 1 are stacked in the containing position as shown inFIG. 5 , it is possible to stably form the containingspace 88 in which the encapsulatingsheet 96 is contained. On the other hand, when the two encapsulatingsheet containers 1 are stacked in the stacking position as shown inFIG. 9 , it is possible to retain the short stacking length of the two encapsulatingsheet containers 1 when the encapsulatingsheet 96 is not contained. - This allows the quality of the encapsulating
sheet 96 to be reliably retained. - When the two encapsulating
sheet containers 1 are stacked as shown inFIG. 7 , the plurality of first large recessedportions 52B of the pair offirst positioning portions 32B are brought into engagement with the plurality of first supportingportions 53A of the pair offirst positioning portions 32A. This allows reliable positioning to be performed such that, in the containing position, when projected in the upper-lower direction, the first projectingportions 17B of the encapsulatingsheet container 1B overlap the first recessedportions 19A of the encapsulatingsheet container 1A and the first recessedportions 19B of the encapsulatingsheet container 1B overlap the first projectingportions 17A of the encapsulatingsheet container 1A. In addition, the plurality of second large recessedportions 62B of the pair ofsecond positioning portions 33B are brought into engagement with the plurality of second supportingportions 63A of the pair ofsecond positioning portions 33A. This allows reliable positioning to be performed such that the second projectingportions 27B of the encapsulatingsheet container 1B overlap the second recessedportions 29A of the encapsulatingsheet container 1A and the second recessedportions 29B of the encapsulatingsheet container 1B overlap the second projectingportions 27A of the encapsulatingsheet container 1A. - As a result, in each of the containing position and the stacking position, the two encapsulating
sheet containers 1 can stably be stacked. - While the illustrative embodiments of the present invention are provided in the above description, such is for illustrative purpose only and it is not to be construed as limiting the scope of the present invention. Modification and variation of the present invention that will be obvious to those skilled in the art is to be covered by the following claims.
