Title: Container for encasement

Description:
TECHNICAL FIELD 
     The present invention relates to a container for encasement, specifically, a container for encasing a bottle. 
     BACKGROUND ART 
     Some containers for encasing a bottle of drinking water, sake, wine, whisky, distilled spirit, juice, or the like are unfolded in a flat shape and stacked when not used; and individually folded by a predetermined way when used. Some of these containers for encasement have a special shape to conform the size and the shape of each bottle. Furthermore, some containers for encasement used for a gift are decorated on the outer face. The material of the containers for encasement is generally a paper such as a coated board or a cardboard (refer to Patent Documents 1 and 2). 
     The containers for encasement that have a simple structure are vulnerable to impact, for example, drop impact. Even if resisting to impact, the containers for encasement are just used for encasing a bottle. For example, containers for encasing a bottle of sake or wine are disposed or used for accessory cases when or after sake or wine is drunk. Some of the containers for encasement may be kept together with the bottle in memory. 
     By the way, generally, fantastic and romantic worlds or the like are often produced variously by darkening the inside and lighting candles in a restaurant or the like to enhance the mood and to make meals more delicious. This atmosphere is created by using the flame of a candle in candle sleeves and candle holders (refer to Patent Document 3). Such creation of atmosphere is also compounded in various eating places other than restaurants, wedding receptions, parties, and general households. 
     In the general household, candle sleeves and candle holders should usually be purchased separately from an alcohol drink such as sake or wine. However, the sales locations for alcohol drinks and candle sleeves may be away from each other at a considerable distance, even in a same store, for example, a large-scale store. In this case, it is inconvenient to purchase both of them due to the long distance. Therefore, the inventors have invented a container for encasement in which a part of the container for encasing a bottle is formed as a candle sleeve to alleviate the inconvenience to purchase a candle sleeve separately from a bottle when drinking beverage, especially alcohol drink in a bottle while enjoying the effect of the atmosphere created by the candle sleeve. Therefore, the container for encasement can notably exert the effect of creation of the atmosphere when the part of the container is used as a candle sleeve (refer to Patent Document 4). 
     The container for encasement described in Patent Document 4 is vertically long, which is laid to let in and out a laid bottle. The container has a widely-formed opening to let in and out a bottle and a bottle base locking part to prevent a bottle from rolling, so that a bottle can be safely and easily inserted and withdrawn from the container. 
     On the other hand, assumingly, the vertically long “paper box for encasement” described in FIGS. 1 to 8 of Patent Document 1 lets in and out a bottle by using the “lid 19” in the standing position. Furthermore assumingly, the vertically long “container for a bottle” described in Patent Document 2 also lets in and out a bottle by using the “mouth of the container for a bottle 1” in the standing position. However, these containers inconveniently let in and out a bottle because the openings of the “lid 19” and the “mouth of the container for a bottle 1” that are formed in the upper part of the vertically long container are small.

     DESCRIPTION OF EMBODIMENTS 
     The present invention will be more specifically described below with reference to preferable embodiments. The embodiment to be described below is merely example embodiments of the present invention and do not limit the present invention. 
     The container for encasement  1  of the present invention includes an internal container for encasement  2  and an external container for encasement  3 . The internal container for encasement  2  includes an internal container main body  2   a  provided with a left opening and closing case  10 , a right opening and closing case  20 , and a bottom  30 ; a lid  40 ; and a base  50 . The base  50  includes a base support  60  for height adjustment to correspond to different heights of bottles to be encased in the container. In this embodiment, all the components of the internal container for encasement  2  and the external container for encasement  3  are made from Japanese paper and of polyethylene terephthalate, respectively. However, the materials may be changed as needed. The top, the bottom, the right, and the left directions are conveniently represented by arrows to explain the attached drawings. 
       FIG. 1  shows an expansion plan of the left opening and closing case  10  according to one embodiment of the present invention.  FIG. 2  shows an expansion plan of the right opening and closing case  20  according to one embodiment of the present invention.  FIG. 3  shows an expansion plan of the bottom  30  according to one embodiment of the present invention. The right opening and closing case  20  shown in  FIG. 2  is assembled and placed, facing the left opening and closing case  10  shown in  FIG. 1 . Since the right opening and closing case  20  shown in  FIG. 2  has the same structure and function as the left opening and closing case  10  shown in  FIG. 1 , the explanation of  FIG. 2  is omitted. The reference signs of the components shown in  FIG. 2  are the same as those shown in  FIG. 1 . 
     As shown in  FIG. 1 , the left opening and closing case  10  is formed so that it can be assembled by folding one blank. The left opening and closing case  10  is formed of a bottle mouth protector  11  and a sidewall  12 , and a bottom board  13  that are serially connected in order from the top. The sidewall  12  is connected with lock pieces  14 ,  14 , one each on the left and right sides. To protect an encased bottle, the container for encasement  1  is assembled by folding the predetermined components of the left opening and closing case  10  at predetermined fold lines to form a double wall. The fold lines each represent a mountain fold line or a valley fold line. The mountain fold is to fold a blank so that the fold line comes outside. The valley fold is to fold a blank so that the fold line comes inside. In the attached drawings, the fold lines are depicted by dashed-dotted lines. 
     The bottle mouth protector  11  is to protect the mouth of a bottle from external impact when a bottle is encased in the container for encasement  1 . The bottle mouth protector  11  is formed in the upper part of the left opening and closing case  10 . The sidewall  12  is to protect the base of a bottle from external impact when a bottle is encased in the container for encasement  1 . The sidewall  12  is connected with the lower side of the bottle mouth protector  11 . The bottom board  13  connected with the lower side of the sidewall  12  to connect with the bottom  30 . As described above, the mouth and the base of an encased bottle are protected by the left opening and closing case  10  although the bottom is protected by the base  50  and the base support  60  that will be described later. 
     The bottle mouth protector  11  has a rectangular engaging piece  11   a , an inversed, approximately-U-shaped bottle mouth protection lower face  11   b , an approximately-concave bottle mouth protection front face  11   c , and an approximately-rectangle bottle mouth protection upper face  11   d  that are serially connected through the mountain fold line  111   a , the valley fold line  111   b , and the mountain fold line  111   c , respectively, in order from the top. A cutout is formed in a part of the right and the left sides of the bottle mouth protection lower face  11   b . The right and the left sides of the bottle mouth protection front face  11   c  are each connected with insertion tongue pieces  11   e ,  11   e  through valley fold lines  111   d ,  111   d , respectively. A convex piece  11   f  is formed on the lower side of the bottle mouth protection upper face  11   d . Mountain fold lines  111   j ,  111   j  are each formed in the right and left of the lower side of the bottle mouth protection upper face  11   d , respectively. The sidewall  12  is connected with the lower side of the bottle mouth protection upper face  11   d.    
     The container for encasement  1  is creased along the fold lines to easily fold. For example, the long fold line that is hardly folded is partially or completely perforated as needed so that it is easily folded. 
     The vertical direction and the horizontal direction in the attached drawings are defined herein as the “length” direction and the “width direction” direction, respectively. The engaging piece  11   a  and the upper part of the bottle mouth protection lower face  11   b  and the bottle mouth protection upper face  11   d  are formed in a same width. The bottle mouth protection lower face  11   b  and the bottle mouth protection upper face  11   d  are formed in a same length. The lower side of the bottle mouth protection lower face  11   b  and the bottle mouth protection front face  11   c  is formed in a width less than the length of the engaging piece  11   a  by the thickness of the blank. “Length” will be used for the fold lines, the side, and the like regardless of the vertical and the horizontal directions. 
     A rectangle bottle mouth engaging part  11   g  is formed in the region that extends over the bottle mouth protection lower face  11   b  and the bottle mouth protection front face  11   c . Valley fold lines  111   f  and  111   h  are formed in the top and the bottom sides of the bottle mouth engaging part  11   g , respectively. A mountain fold line  111   g  is formed in the approximate center. Cuts  111   i ,  111   i  are each formed in the right and the left sides, respectively. In this bottle mouth engaging part  11   g , a hollow that is capable to engage with the mouth of an encased bottle is formed of the valley fold lines  111   f  and  111   h , the mountain fold line  111   g , and the cuts  111   i ,  111   i  when the left opening and closing case  10  is assembled, so that the mouth of the bottle can be protected. 
     The bottle mouth protector  11  forms a box with a hallow (bottle mouth engaging part  11   g ) when the left opening and closing case  10  is assembled. The bottle mouth protection upper face  11   d  forms the upper face of this box. The bottle mouth protection lower face  11   b  forms the lower face. The bottle mouth protection front face  11   c  forms the front face. The insertion tongue pieces  11   e ,  11   e  form the side faces. The back face of the box is formed of the top front inside wall  12   a  and the top exterior inside walls  12   b ,  12   b  that are included in the sidewall  12 . 
     The sidewall  12  forms three sidewalls of the right, the left, and the back faces when the left opening and closing case  10  is assembled. Each sidewall is a double wall with an inside wall and an outside wall. The approximately rectangle top front inside wall  12   a  is connected with the lower side of the bottle mouth protection upper face  11   d  of the bottle mouth protector  11  through the right and the left mountain fold lines  111   j ,  111   j . The rectangular top exterior inside walls  12   b ,  12   b  are each connected with the right and the left of the top front inside wall  12   a  through valley fold lines  112   a ,  112   a , respectively. A convex cut is provided between the right and the left mountain fold lines  111   j ,  111   j , projecting to the bottle mouth protection upper face  11   d , to form the convex piece  11   f . The term “outside” herein collectively includes “left side” and “right side.” 
     The lower sides of the right and the left top exterior inside walls  12   b ,  12   b  and the top front inside wall  12   a  are connected with approximately rectangle exterior outside walls  12   c ,  12   c  and a front outside wall  12   d  through the valley fold lines  112   b ,  112   b , and  112   c , respectively. The bottom edges  112   e ,  112   e  of the exterior outside walls  12   c ,  12   c  are formed to decline from the outside to the inside. The exterior outside walls  12   c ,  12   c  are each connected with the front outside wall  12   d  through valley fold lines  112   d ,  112   d , respectively. The lengths of the exterior outside walls  12   c ,  12   c  and the front outside wall  12   d  are set based on the height of a bottle or the like to be encased. The widths of the exterior outside walls  12   c ,  12   c  and the front outside wall  12   d  are set based on the diameter of the base of a bottle or the like to be encased. Since the left opening and closing case  10  and the right opening and closing case  20  form a pair of opening and closing cases, the width of each exterior outside wall  12   c  and  12   c  only has to be about a half of that of the front outside wall  12   d . The exterior outside walls  12   c ,  12   c  are the same in width. 
     Rectangular insertion space-forming walls  12   f ,  12   f  are each formed in the right and the left of the exterior outside wall  12   c ,  12   c  through a valley fold line  112   g ,  112   g , respectively. The top of each insertion space-forming wall  12   f ,  12   f  is formed below the tops of the top exterior inside walls  12   b ,  12   b  by twice the length of each top exterior inside wall  12   b ,  12   b . Accordingly, when the left opening and closing case  10  is assembled, the top exterior inside walls  12   b ,  12   b  and the top front inside wall  12   a  are folded along the valley fold lines  112   b ,  112   c ,  112   b , respectively, to bring the tops of the top exterior inside walls  12   b ,  12   b  to contact with the tops of the respective insertion space-forming walls  12   f ,  12   f  The insertion space-forming walls  12   f ,  12   f  are formed in the approximately same width as the thickness of the blank to let in the right and the left open angle limitation pieces  33  and  34  of the bottom  30  that will be described later. 
     Approximately rectangle exterior inside walls  12   g ,  12   g  are each connected with the right and the left sides of the insertion space-forming wall  12   f ,  12   f  through a valley fold line  112   h ,  112   h , respectively. Cutouts  12   h ,  12   h  are each formed in the upper parts of respective exterior insides wall  12   g ,  12   g . The cutouts  12   h ,  12   h  are each formed to engage the right and the left edges of the engaging piece  11   a  of the bottle mouth protector  11  with the right and the left edges of the bottle mouth protection lower face  11   b , respectively, when the left opening and closing case  10  is assembled. Furthermore, the exterior outside walls  12   c ,  12   c  each form a double outside wall, and the exterior inside walls  12   g ,  12   g  each form a double inside wall. 
     Approximately rectangle front inside walls  12   i ,  12   i  are each connected with the right side of the right exterior inside wall  12   g  and the left side of the left exterior inside wall  12   g  through each two mountain fold lines  112   i ,  112   i  and  112   i ,  112   i , respectively. The width of the front inside walls  12   i ,  12   i  are set to a half of that of the front outside wall  12   d . Accordingly, when the left opening and closing case  10  is assembled, the front outside wall  12   d  form a double outside wall, and the front inside walls  12   i ,  12   i  each form a double inside wall. 
     A convex cut is provided between the left mountain fold lines  112   i ,  112   i , projecting to the left exterior inside wall  12   g , to form a convex piece  12   j . This convex piece  12   j  is formed in an approximately same width as that of the insertion space-forming wall  12   f . Accordingly, the edge of the convex piece  12   j  is in contact with the exterior outside wall  12   c  (the inside face of the exterior outside wall  12   c ) when the left opening and closing case  10  is assembled by folding along predetermined fold lines, so that the insertion space  12   k  in which the left open angle limitation piece  33  of the bottom  30  that will be described later is inserted does not collapse. In the same way as the left, a convex cut is provided between the right mountain fold lines  112   i ,  112   i , projecting to the right exterior inside wall  12   g , to form a convex piece  12   j . This convex piece  12   j  is formed in an approximately same width as that of the insertion space-forming wall  12   f . Accordingly, the edge of the convex piece  12   j  is in contact with the exterior outside wall  12   c  (the inside face of the exterior outside wall  12   c ) when the left opening and closing case  10  is folded along predetermined fold lines and assembled, so that the insertion space  12   k  in which the right open angle limitation piece  34  of the bottom  30  that will be described later is inserted does not collapse. 
     The upper side of each exterior inside wall  12   g ,  12   g  is connected with a lock piece  14 ,  14  through a mountain fold line  112   j ,  112   j . Lock cutouts  14   a ,  14   a  are each formed in lock pieces  14 ,  14 , respectively. Accordingly, the lock cutouts  14   a ,  14   a  are engaged with each other to lock the lock pieces  14 ,  14  when the left opening and closing case  10  is assembled, so that the upper part of the left opening and closing case  10  can be strengthened. 
     The approximately rectangle bottom board  13  is formed below the front outside wall  12   d  through valley fold lines  112   f ,  112   f . A convex cut is provided between the valley fold lines  112   f ,  112   f , projecting to the bottom board b 13 , to form a convex piece  12   e.    
       FIG. 2  shows an expansion plan of the right opening and closing case  20  according to one embodiment of the present invention. As described above, there is an arrangement relationship between the left opening and closing case  10  shown in  FIG. 1  and the right opening and closing case  20  shown in  FIG. 2  that face each other. Since the components and the functions are the same, the description of  FIG. 2  is omitted. The same reference signs of the components of the left opening and closing case  10  are assigned to those of the right opening and closing case  20 . In the description of  FIG. 1 , the left opening and closing case  10  only has to be deemed to be replaced with the right opening and closing case  20 . 
       FIG. 3  shows an expansion plan of the bottom  30  according to one embodiment of the present invention. An approximately square bottom board  31  is formed in the center of the bottom  30 . The length of each side of the bottom board  31  is approximately twice that of the above-mentioned bottom board  13 . The respective centers of the right and the left sides of the bottom board  31  are each connected with bottom board insertion lock pieces  32 ,  32  through valley fold lines  131   a ,  131   a , respectively. The left bottom board insertion lock piece  32  is formed in the shape of a tongue piece provided with fingernails  32   a ,  32   a  that each project to the upper and the lower edges, respectively. When assembled, the left opening and closing case  10  is folded along the valley fold lines  112   f ,  112   f , and the left bottom board insertion lock piece  32  is inserted in one insertion hole  13   a  (refer to  FIG. 8 ) formed between the bottom board  13  and the convex piece  12   e . The valley fold line  131   a  is formed in a length that is approximately the same as the width of the convex piece  12   e . In other words, the bottom board insertion lock piece  32  is longer than the insertion hole  13   a  by the heights of the fingernails  32   a ,  32   a . The fingernails  32   a ,  32   a  are forced to be inserted when the bottom board insertion lock piece  32  is inserted in the insertion hole  13   a , so that the inserted fingernails  32   a ,  32   a  are locked in the insertion hole  13   a . In the same way as the left, for the right bottom board insertion lock piece  32 , the fingernails  32   a ,  32   a  of the other bottom board insertion lock piece  32  can be locked in the other insertion hole  13   a  formed between the bottom board  13  and the convex piece  12   e  when the right opening and closing case  20  is assembled. As the result, the bottom board  30  can close the bottom of each of the right and the left opening and closing cases  10 ,  20 . 
     The lower side of the bottom board  31  is connected with a left open angle limitation piece  33  and a right open angle limitation piece  34  in the right and the left, respectively, through a valley fold line  131   b . The left open angle limitation piece  33  is an approximately trapezoidal flap, in which the left side  133   a  stands vertically, the right side  133   b  inclines, and the lower bottom is shorter than the upper bottom. The right open angle limitation piece  34  is an approximately trapezoidal flap, in which the left side  134   b  inclines, the right side  134   a  stands vertically, and the lower bottom is shorter than the upper bottom. In other words, the right open angle limitation piece  34  has the shape of the left open angle limitation piece  33  that is mirror-reversed around the centerline (not shown in the attached drawings) in the vertical direction of the bottom  30 . The left open angle limitation piece  33  and the right open angle limitation piece  34  are connected with each other in their respective upper parts. The components with the reference signs  33  and  34  are named as “left open angle limitation piece” and “right open angle limitation piece,” respectively, but may be named as “left rotation amount limitation piece” and “right rotation amount limitation piece,” “left position limitation piece” and “right position amount limitation piece,” or “left distance limitation piece” and “right distance limitation piece,” 
     The left open angle limitation piece  33  and the right open angle limitation piece  34  on the upper side of the bottom board  31  have the shape of the left open angle limitation piece  33  and the right open angle limitation piece  34 , respectively, on the lower side of the bottom board  31  that are mirror-reversed around the centerline in the horizontal direction of the bottom  30 . Since the left open angle limitation piece  33  and the right open angle limitation piece  34  on the upper side have the same configuration as those on the lower side, the explanation is omitted. 
       FIG. 4  shows an expansion plan of the lid  40  of an internal container for encasement  2  according to one embodiment of the present invention. The lid  40  has an approximately square upper face  41  in the center in which a circular opening  41   a  opens. The upper face  41  is connected with a left, a right, a front, and a back faces  42 ,  43 ,  44 , and  45  through mountain fold lines  141   a ,  141   a  and  141   b ,  141   b  that are provided along the right, the left, the upper, and the lower sides of the upper face  41 , respectively. The opening  41   a  only has to have an internal diameter enough to let in a finger of a person&#39;s. The upper and the lower sides of the left face  42  are each connected with left face flaps  42   a ,  42   a  through mountain fold lines  142   a ,  142   a . The upper and the lower sides of the right face  43  are each connected with right face flaps  43   a ,  43   a  through mountain fold lines  143   a ,  143   a , respectively. The lower side of the front face  44  is connected with a front face insertion piece  44   a  through a mountain fold line  144   a . The upper side of the back face  45  is connected with a back face insertion piece  45   a  through a mountain fold line  145   a.    
     The left side of the left face  42  is connected with a lower face  46  through mountain fold lines  142   a ,  142   a . A tongue-shaped lock piece  42   b  is formed between the mountain fold lines  142   b ,  142   b , projecting to the lower face  46 . The left side of the lower face  46  is connected with a lower face insertion piece  46   b  through mountain fold lines  146   a ,  146   a . A tongue-shaped lock piece  46   a  is formed between the mountain fold lines  146   a ,  146   a , projecting to the lower face  46 . The lock pieces  42   b  and  46   a  may have a same shaped tongue pieces. 
       FIG. 5  shows an expansion plan of the base  50  of an internal container for encasement  2  according to one embodiment of the present invention. The base  50  has a very similar structure as the lid  40 . The base  50  has an approximately square upper face  51  in which an approximately circular opening  51   a  opens. The upper face  51  is connected with a left, a right, a front, and a back faces  52 ,  53 ,  54 , and  55  through mountain fold lines  151   a ,  151   a  and  151   b ,  151   b  that are provided on the right, the left, the upper, and the lower sides of the upper face  51 , respectively. In the hinges  57 ,  57  that are each on the top and the bottom of the opening  51   a , respectively, partially circular flaps  51   b ,  51   b  with a chord length less than the internal diameter of the opening  51   a  are each formed. The internal diameter of the opening  51   a  is formed based on the diameter of the base of an encased bottle or the like. The base support  60  to be described later is attached to the bottom of the base  50  according to this embodiment. The base  50  may not be provided with a base support  60  as needed. In this case, the flaps  51   b ,  51   b  are formed in a hemicycle, and the internal diameter of the opening  51   a  is increased according to the diameter of the base of an encased bottle. Preparing two or more bases  50  that have an opening  51   a  with a different size and two or more base supports  60  that have side faces of a different height enables one container for encasement  1  to deal with two or more kinds of bottles with a different height and a different diameter of the base. 
     The upper and the lower sides of the left face  52  are connected with a left face flap  52   a ,  52   a  through a mountain fold line  152   a ,  152   a . The upper and the lower sides of the right face  53  are connected with a right face flap  53   a ,  53   a  through a mountain fold line  153   a ,  153   a . The lower side of the front face  54  is connected with a front face insertion piece  54   a  through a mountain fold line  154   a . The upper side of the back face  55  is connected with a back face insertion piece  55   a  through a mountain fold line  155   a . The left side of the left face  52  is connected with a lower face  56  through a mountain fold line  152   a . The left side of the back face  56  is connected with a back face insertion piece  56   a  through a mountain fold line  156   a . The lid  40  forms a box that has an opening when assembled. 
       FIG. 6  shows an expansion plan of the base support  60  of an internal container for encasement  2  according to one embodiment of the present invention 
     The base support  60  has an approximately square upper face  61 . The upper face  61  is connected with a left, a right, a front, and a back faces  62 ,  63 ,  64 , and  65  through mountain fold lines  161   a ,  161   a  and  161   b ,  161   b  that are provided on the right, the left, the upper, and the lower sides of the upper face  61 , respectively. As described above, the base support  60  is attached to the base  50  and capable to adjust its height according to the height of an encased bottle. 
       FIG. 7  shows an expansion plan of an external container for encasement  3  according to one embodiment of the present invention. The external container for encasement  3  is unfolded in one approximately rectangular shape. In the external container for encasement  3 , an overlap width  3   b  is formed at the left edge. The overlap width  3   b  and four sidewalls  3   a  with a same width are serially connected in the right direction from the overlap width part  3   b  through each of four valley fold lines  3   c . When the external container for encasement  3  is assembled, the overlap width  3   b  is glued with the sidewall  3   a  at the edge of the right side to form a square hollow. After assembled, the external container for encasement  3  covers the internal container for encasement  2  for use. 
     Since the external container for encasement  3  is used as a candle sleeve, the sidewalls have a predetermined translucent pattern (now shown in the attached drawings). When the external container for encasement  3  is used as a candle sleeve, a candle is set in the external container for encasement  3 . In this case, any one of the lid  40 , the base  50 , the base support  60 , and the like may be used as a candle stand, or a special candle stand may be used. Changing the pattern in the sidewalls according to surroundings effectively creates various atmospheres. According to the present invention, the light radiated from the flame of a candle set in the candle sleeve projects the translucent pattern formed on the side faces of the candle sleeve to the surroundings, so that an atmosphere at the user&#39;s desire can be created. For example, if the translucent pattern is formed to tell the traditional culture of Japan, its atmosphere can be created. 
     How to assemble the container for encasement  1  according to one embodiment of the present invention will be described below with reference to  FIGS. 8 to 14 .  FIG. 8  shows a perspective view of an assembled left opening and closing case  10  according to one embodiment of the present invention.  FIG. 9  shows a perspective view of an assembled bottom  30  according to one embodiment of the present invention.  FIG. 10  shows a perspective view in which the bottom  30  is attached to the left opening and closing case  10 , according to one embodiment of the present invention.  FIG. 11  shows a perspective view in which the bottom  30  is attached to the left opening and closing case  10  and the right opening and closing case  20 , according to one embodiment of the present invention. Specifically,  FIG. 11  illustrates an assembled internal container main body  2   a .  FIG. 12  shows a perspective view of an assembled lid  40  according to one embodiment of the present invention.  FIG. 13  shows a perspective view in which the base support  60  is attached to the base  50 , according to one embodiment of the present invention.  FIG. 14  shows a perspective view of an assembled container for encasement  1  according to one embodiment of the present invention. 
     As shown in  FIG. 8 , the left opening and closing case  10  that has been by predetermined fold lines and assembled forms a box with a double wall that opens to let in and out a bottle. The bottle mouth protection upper face  11   d , the top front inside wall  12   a , the top exterior inside walls  12   b ,  12   b  form an fixing concave  15   a  to fix a half of the lid  40 . The lock piece  42   b  of the assembled lid  40  is inserted in the insertion hole  11   j  to lock a half of the lid  40  in the left opening and closing case  10 . The bottle mouth engaging part  11   g  is formed to engage and fix the mouth of an encased bottle so that the mouth of an encased bottle is protected from external impact. The exterior outside walls  12   c ,  12   c  and the front outside wall  12   d  form a half of the outside walls of the internal container for encasement  2 . The exterior outside wall  12   c , the insertion space-forming wall  12   f , the exterior inside wall  12   g , and the convex piece  12   j  form an insertion space  12   k . The right opening and closing case  20  has the structure paired with that of the left opening and closing case  10  in the internal container main body  2   a  and assembled in the same way as the left opening and closing case  10 . Thus, the explanation is omitted. 
     As shown in  FIG. 9 , the bottom  30  is folded in predetermined fold lines to stand the pieces in the same direction (the upper direction in  FIG. 9 ) and attached to the right and the left opening and closing cases  10  and  20  to form the bottom of the internal container main body  2   a . The bottom  30  is a means to limit the open range of the right and the left opening and closing cases  10  and  20  when they are opened. The details will be described later. 
     As shown in  FIG. 10 , the left open angle limitation pieces  33 ,  33  of the bottom  30  that have been folded in predetermined fold lines and assembled are each inserted in the insertion spaces  12   k ,  12   k  of the left opening and closing case  10 , respectively. At this time, the bottom board insertion lock piece  32  of the bottom  30  is inserted in the insertion hole  13   a  to lock a half of the bottom  30  in the left opening and closing case  10 . 
     As shown in  FIG. 11 , the right open angle limitation pieces  34 ,  34  of the bottom  30  that have been folded in predetermined fold lines and assembled are each inserted in the insertion spaces  12   k ,  12   k  of the right opening and closing case  20 , respectively. At this time, the bottom board insertion lock piece  32  of the bottom  30  is inserted in the insertion hole  13   a  to lock the other half of the bottom  30  in the right opening and closing case  20 . The insertion space-forming walls  12   f ,  12   f  are each formed to be contact with the left opening and closing case  10  and the right opening and closing case  20 , respectively. This is the situation when the right and the left opening and closing cases  10  and  20  are closed. This situation may represent that the internal container main body  2   a , the internal container for encasement  2 , and the container for encasement  1  are also closed. 
     As shown in  FIG. 12 , the lid  40  is folded along predetermined fold lines and assembled to form to a box. The lid  40  can be easily attached to and detached from the internal container main body  2   a  by putting a finger of user&#39;s in the opening  41   a . When the lid  40  is engaged with the fixing concave  15  formed of the fixing concave  15   a ,  15   a  of each of the right and the left opening and closing cases  10  and  20  after an bottle is encased, the lock pieces  42   b  and  46   a  are each inserted and locked in the insertion hole  11   j  formed of the bottle mouth protection upper face  11   d  and the convex piece  11   f  of each of the right and the left opening and closing case  10  and  20 , respectively. Accordingly, the right and the left opening and closing cases  10  and  20  can be kept closed. 
     As shown in  FIG. 13 , the base  50  is folded along predetermined fold lines and assembled to form a box in which an approximately circular opening  51   a  opens. The internal diameter of the opening  51   a  of the base  50  is formed based on the diameter of the base of an encased bottle or the like. The flaps  51   b ,  51   b  are rotatable through the respective hinges  57 ,  57 . The base  50  is fixed in the bottom of the internal container main body  2   a . In addition, the bottom of an encased bottle is inserted to the opening  51   a  of the base  50 . In this embodiment, the base support  60  that has been folded along predetermined fold lines and assembled is attached to the lower face  56  of the base  50  to correspond to the height of a bottle. However, the base support  60  may be removed depending on the height of a bottle. According to this structure as described above, the bottom of an encased bottle is protected from external impact. 
     The base  50  and optionally the base support  60  are provided in the bottom of the internal container main body  2   a  that is formed of the right and the left opening and closing cases  10  and  20  and the bottom  30 . Then, the external container for encasement  3  covers the internal container for encasement  2  that is formed with the lid  40  provided in the top to form the container for encasement  1  as shown in  FIG. 14 . Therefore, the vertically long container for encasement  1  according to this embodiment can easily let a bottle in or out, or in and out in the standing position. The container for encasement  1  according to this embodiment that is containing a bottle of sake, wine, or the like can be wrapped with a cloth wrapper and used for a gift. In this case, the pattern of the side faces of the external container for encasement  3  used as a candle sleeve should be the same as that of a wrapper. 
       FIGS. 15 to 17  show that the right and the left opening and closing cases  10  and  20  are being opened to take out a bottle  7  encased in the container for encasement  1 .  FIG. 15  shows that the container for encasement  1  is half-opened. In this situation, the external container for encasement  3  and the lid  40  are removed from the container for encasement  1 , and the right opening and closing case  20  is fully opened while a bottle  7  encased in the left opening and closing case  10 . The left opening and closing case  10  to which the bottom  30  is attached stands approximately upright. The right opening and closing case  20  is inclined at a predetermined angle. 
       FIG. 16  shows that the container for encasement  1  is fully opened. In this situation, the left opening and closing case  10  is fully opened as well as the right opening and closing case  20 . In the same way as the right opening and closing case  20 , the left opening and closing case  10  is opened and inclined at a predetermined angle. A bottle  7  can be inserted in and withdrawn from the container for encasement  1  usually in this fully opened situation. While the container for encasement  1  is fully opened, the angle where the right and the left opening and closing cases  10  and  20  open, which is the open angle, is limited. Therefore, an encased bottle  7  can be easily withdrawn from the container  1  for encasement in their standing positions. Furthermore, a bottle  7  can be easily inserted in the container  1  for the encasement in their standing positions. 
       FIG. 17  shows an elevation view of a fully opened container for encasement  1 . When the container for encasement  1  is closed, in other words, when the right and the left opening and closing cases  10  and  20  are closed, the insertion space-forming walls  12   f ,  12   f  are in close contact with each other in the vertical direction and approximately fall in the centerline CL in the vertical direction of the encased bottle  7 . The angle between the left opening and closing case  10  (insertion space-forming wall  12   f ) and the centerline CL is designated as the open angle θ when the left opening and closing case  10  is opened. In this case, the open angle θ with respect to the fully opened left opening and closing case  10  is set to be approximately equal to the inclination angle θ 0  between the right side  133   b  of the left open angle limitation piece  33  of the bottom  30  and the centerline CL. In the same way as the left, the open angle θ with respect to the fully opened right opening and closing case  20  (insertion space-forming wall  12   f ) is set to be approximately equal to the inclination angle θ 0  between the left side  134   b  of the right open angle limitation piece  34  of the bottom  30  and the centerline CL. The right and the left opening and closing cases  10  and  20  (insertion space-forming walls  12   f ) are prevented from opening at more than the open angle θ. 
       FIG. 18  shows the reason why the open angle is limited.  FIG. 18( a )  shows that the container for encasement  1  is (the right and the left opening and closing cases  10  and  20  are) closed.  FIG. 18( b )  shows that the container for encasement  1  is opening.  FIG. 18( c )  shows that the container for encasement  1  is fully opened. 
     While the container for encasement  1  is closed, the left open angle limitation piece  33  is inserted in the insertion space  12   k  formed of the front outside wall  12   d , the exterior outside wall  12   c , and the exterior inside wall  12   g  of the left opening and closing case  10 . On the other hand, the right open angle limitation piece  34  is inserted in the insertion space  12   k  formed of the front outside wall  12   d , the exterior outside wall  12   c , the insertion space-forming wall  12   f , and the exterior inside wall  12   g  of the right opening and closing case  20 . While the left opening and closing case  10  is closed, the left side  133   a  of the left open angle limitation piece  33  and the front outside wall  12   d  (the inside face of the front outside wall  12   d ) are preferably in close contact with each other, but there may be a small space between them. 
     In this situation, the right side  133   b  of the left open angle limitation piece  33  is further away from the insertion space-forming wall  12   f  (the inside face of the insertion space-forming wall  12   f ) as it goes from the bottom to the top. In the same way as the left, while the right opening and closing case  20  is closed, the left side  134   a  of the right open angle limitation piece  34  and the front outside wall  12   d  (the inside face of the front outside wall  12   d ) are preferably in close contact with each other, but there may be a small space between them. In this situation, the left side  134   b  of the right open angle limitation piece  34  is further away from the insertion space-forming wall  12   f  (more specifically, the inside face of the insertion space-forming wall  12   f ) as it goes from the bottom to the top. 
     When the right and the left opening and closing cases  10  and  20  are opened from this closed situation, the left opening and closing case  10  is first rotated around the valley fold line  112   f  as the axis to the left as shown in  FIG. 18( b ) . Then, the front outside wall  12   d  of the left opening and closing case  10  is gradually separated from the left side  133   a  of the closely contacted left open angle limitation piece  33 . However, the separated upper part of the insertion space-forming wall  12   f  gradually approaches the right side  133   b  of the left open angle limitation piece  33 . When the open angle θ with respect to the left opening and closing case  10  (insertion space-forming wall  12   f ) is approximately equal to the inclination angle θ 0  between the right side  133   b  of the left open angle limitation piece  33  and the centerline CL as shown in  FIG. 18( c ) , the insertion space-forming wall  12   f  is in contact with the right side  133   b , and the rotation is stopped. Finally, the left opening and closing case  10  is prevented from opening at more than the open angle θ when stopped to rotate. 
     In the same way as the left, the right opening and closing case  20  is rotated around the valley fold line  112   f  as the axis to the right as shown in  FIG. 18( b ) . Then, the front outside wall  12   d  of the right opening and closing case  20  is gradually separated from the right side  134   a  of the closely contacted right open angle limitation piece  34 . However, the separated upper part of the insertion space-forming wall  12   f  gradually approaches the left side  134   b  of the right open angle limitation piece  34 . When the open angle θ with respect to the right opening and closing case  20  (insertion space-forming wall  12   f ) is approximately equal to the inclination angle θ 0  between the left side  134   b  of the right open angle limitation piece  34  and the centerline CL as shown in  FIG. 18( c ) , the insertion space-forming wall  12   f  is in contact with the left side  134   b , and the rotation is stopped. Finally, the right opening and closing case  20  is prevented from opening at more than the open angle θ when stopped to rotate. 
     The open angles of the right and the left opening and closing cases  10  and  20  (insertion space-forming walls  12   f ,  12   f ) that are described above can be deemed to be replaced with the rotation amounts (or rotating amounts) of the right opening and closing cases  10  and  20  (insertion space-forming walls  12   f ,  12   f ) that rotate around the centerline CL. 
     The range where the container for encasement  1  opens is explained above in terms of angle but can also be explained as described below in terms of position. When the left opening and closing case  10  is rotated around the valley fold line  112   f  as the axis to the left, and then the bottom (inside face) of the insertion space-forming wall  12   f  is in contact with the right side  133   b  at the position P 1  where “the length of the bottom edge  112   e  of the exterior outside wall  12   c ” is equal to “the straight-line distance from the valley fold line  112   f  to the right side  133   b ,” and the rotation is stopped (refer to  FIG. 18( c ) ). As the left opening and closing case  10  goes upward from the position P 1  of the right side  133   b , “the straight-line distance from the valley fold line  112   f  to the right side  133   b ” becomes more than “the length of the bottom edge  112   e  of the exterior outside wall  12   c ,” and in other words, the right side  133   b  is linearly inclined as shown in  FIG. 18( c ) . Accordingly, the range where the insertion space-forming wall  12   f  is in contact with the right side  133   b  is longer (or wider). Finally, the left opening and closing case  10  is prevented from rotating upward from the position P 1 . 
     In the same way as the left, when the right opening and closing case  20  is rotated around the valley fold line  112   f  as the axis to the right, and then the bottom (inside face) of the insertion space-forming wall  12   f  is in contact with the left side  134   b  at the position P 1  where “the length of the bottom edge  112   e  of the exterior outside wall  12   c ” is equal to “the straight-line distance from the valley fold line  112   f  to the left side  134   b ,” and the rotation is stopped (refer to  FIG. 18( c ) ). As the right opening and closing case  20  goes upward from the position P 1  of the left side  134   b , “the straight-line distance from the valley fold line  112   f  to the left side  134   b ” becomes more than “the length of the bottom edge  112   e  of the exterior outside wall  12   c ,” and in other words, the left side  134   b  is linearly inclined as shown in  FIG. 18( c ) . Accordingly, the range where the insertion space-forming wall  12   f  is in contact with the left side  134   b  is longer (or wider). Finally, the right opening and closing case  20  is prevented from rotating upward from the position P 1 . 
     It can also be expressed that if the position of the bottom (inside face) of each insertion space-forming wall  12   f ,  12   f  is designated as P 0  while the right and the left opening and closing cases  10  and  20  are closed, the right and the left opening and closing cases  10  and  20  are prevented from opening more than the distance between the positions P 1  and P 0 . 
     In addition, the rotation (rotating) amount and the position P 1  of each of the right and the left opening and closing cases  10  and  20  (each insertion space-forming wall  12   f ,  12   f ) and the open angle θ and the distance P 1 -P 0  between the right and the left opening and closing cases  10  and  20  (insertion space-forming walls  12   f ,  12   f ) are collectively herein referred to as the range where the right and the left opening and closing cases  10  and  20  open. 
     As described above, according to the present invention, the container for encasement provided with an opening and closing case is formed to prevent the opening and closing case from opening more than a predetermined range when the opening and closing case is opened to let a bottle in or out, or in and out in the standing position. Therefore, the container for encasement can easily let a bottle in or out, or in and out in the standing position.
