Therefore, when the third notch is formed at a position corresponding to the size (height) of the container with high storage frequency, the door protrusion member and the side wall protrusion member are connected to the container with high storage frequency. The first door and the second door can be accommodated in the door accommodating portion with the state adjusted according to (height). Further, since the third notch is formed in the upper first door, if the door projection member and the side wall projection member are adjusted corresponding to the formation position of the third notch, the lower first An area in which the container can be accommodated can be formed simply by swinging the upper first door and the contracted second door without swinging one door. Therefore, since a container with a high storage frequency can be stored immediately after swinging each door, there is no need to adjust the door protrusion member and the side wall protrusion member each time, and the work procedure can be reduced.

  According to the cooler box of the fourteenth aspect, in addition to the effect achieved by the cooler box according to the eighth aspect, the door projection member is connected to the lower end portion of the second door so as to be swingable and the front end is upward. It is comprised by the door plate member which inclined, and the door elastic member which urges | biases the door plate member to the 2nd door side direction. Further, the side wall projection member is connected to the lower end portion of the door storage portion so as to be swingable, and the side wall plate member whose front end is inclined upward, and urges the side wall plate member in the first side wall direction. It is comprised by the side wall elastic member. Therefore, the door plate member and the side wall plate member are stored in the door storage portion in an upwardly inclined state, and the thickness in the substantially horizontal direction with respect to the bottom wall of the housing can be shortened, so that the door storage portion becomes large. Can be prevented. Therefore, it is possible to effectively use the housing housing portion and to prevent the cooler box from becoming large-scale.

  Further, when the door plate member and the side wall plate member swing to a position substantially parallel to the bottom wall, the door plate member and the side wall plate member are formed substantially parallel to the bottom wall; In comparison, the area in contact with the bottom surface of the container is increased, so that the container can be more reliably supported.

  Further, when the container is stored, when the container is pushed in the direction of the bottom wall of the casing, the bottom surface of the container comes into contact with the tip inclined upward of the door plate member and the tip inclined upward of the side wall plate member. As the door plate member is pushed in, the door plate member and the side wall plate member swing to a position substantially parallel to the bottom wall of the housing to support the bottom surface of the container. When taking out the container, the door elastic member and the side wall elastic member return the door plate member and the side wall plate member to a position where they are inclined upward. Therefore, since the door plate member and the side wall plate member are swung as the container is stored and taken out, it is not necessary to adjust the door protruding member and the side wall protruding member every time the container is stored and taken out. There is an effect that can be done.

  According to the cooler box according to claim 15, in addition to the effect of the cooler box according to any one of claims 2 to 14, when the first door and the second door swing, Since the first door or the second side wall adjacent to the second side wall is provided with a fixing portion that fixes the first side door or the second side wall to each other, the first door and the second door are swung to be adjacent to the second door. The first door or the second side wall can be firmly fixed. Therefore, even if the food item stored in the housing is carried by the cooler box and is in contact with the first door and the second door, the first door and the second door are fixed. Therefore, it is possible to reliably prevent the container accommodated in the storage area formed by swinging each door from being tilted or tilted.

  According to the cooler box of the sixteenth aspect, in addition to the effect achieved by the cooler box of the fifteenth aspect, the fixing portion is formed at the other end portion of the second door, and the first door and the second door swing. In a state where the first door and the second door are swung, the fitting portion protruding in a convex shape on the second side wall side and the other end portion of the first door or the second side wall are formed. And a fitting groove formed by a concave groove fitting with the fitting portion. Therefore, when the first door and the second door swing, the fitting portion and the fitting groove are fitted, and the second door and the first door or the second side wall are firmly fixed. Accordingly, the first door and the second door can be more reliably prevented from being displaced from the position where the first and second doors are swung, so that the container stored in the storage area formed by the swinging of each door can be more reliably tilted or tilted. There is an effect that can be prevented.

  According to the cooler box of the seventeenth aspect, in addition to the effect produced by the cooler box according to any one of the first to sixteenth aspects, the second door is formed with a communicating portion that communicates the front and back of the second door. Therefore, the inside and the outside of the storage area formed by swinging each door through the communication portion of the second door can be communicated with each other. Therefore, there is an effect that the cooling and heating action can be efficiently performed on the container stored in the storage area.

  According to the cooler box of Claim 18, in addition to the effect which the cooler box in any one of Claim 1 to 17 shows, the insertion part formed in the upper end part of the 1st side wall, and the upper end part of a 2nd door Since both ends of the cap member that tightly seals the upper part of the container and seals the inside can be inserted into the insertion part formed in the container, the container having the cap member narrowly attached to the upper end part is inserted into both ends of the cap member. The part can be stored in a state of being inserted into each insertion part. Therefore, since the container is fixed by the cap member and the two insertion portions, there is an effect that the container can be reliably prevented from tilting or falling. Even when a container filled with liquid is stored, the cap is sealed by the cap member, so even if the cooler box is carried and the container is shaken, the liquid leaks from the opening. There is also an effect that it can be prevented.

  According to the cooler box of the nineteenth aspect, in addition to the effect produced by the cooler box according to the eighteenth aspect, the insertion portions of the first side wall and the second door include recesses formed on the side surfaces of both ends of the cap member. Since the convex portions to be fitted are respectively formed, the cap member can be fixed in a state of being inserted into the insertion portion. Therefore, even when the cooler box is carried and shakes in the vertical direction, the cap member can be prevented from coming off the insertion portion and the container can be prevented from jumping out of the storage area. There is an effect that it can be surely prevented.

  According to the cooler box of claim 20, in addition to the effect produced by the cooler box of claim 18 or 19, the side wall of the housing is formed with a cap storage portion that can store a cap member. There is no need to carry the cap member separately from the cooler box, and the cap member can be prevented from being lost.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an outline of the appearance of the cooler box 1 in the first embodiment of the present invention.

  The cooler box 1 has a substantially box-shaped housing 2 having an opening at the top and having a storage portion in which various items and containers (for example, food items such as food, paper packs, PET bottles, and canned foods) can be stored. And a lid 3 for opening and closing the opening of the housing 2. The housing 2 is composed of a bottom wall 2a and four side walls 2b, 2c, 2d, and 2e, and a region surrounded by the bottom wall 2a and the side walls 2b to 2e serves as a storage portion. The front side of the page is the side wall 2b, the back side of the page facing the side wall 2b is the side wall 2c (second side wall), and the right side of the page is the side wall 2d (first side wall), which faces the side wall 2d. The left side of the drawing is the side wall 2e. The lid 3 is connected to the side wall 2c via two hinges 4. When the lid 3 is closed, the interior of the cooler box 1 is substantially sealed by the stopper 5 of the lid 3 and the receptacle 6 of the side wall 2b. Closed in state.

  In addition, the housing | casing 2 and the lid | cover 3 are comprised by the heat insulation structure, and can maintain the temperature of the accommodated foodstuff. Further, although not shown, a cooling device or a heating device may be attached to improve the cold insulation effect or the heat insulation effect, or a blower device may be attached to improve the cold insulation effect or the heat insulation effect.

  The side wall 2d is formed with a door storage portion 15 in which each door is stored, and a plurality of doors formed in a plate shape are stored in the door storage portion 15 side by side. Among the doors, on the side wall 2c side, a first door 7 and a second door 8 having an upper first door 7a and a lower first door 7b are connected and stored. On the side wall 2b side of the second door 8, two doors connected to the first door 9 and the second door 10 are stored side by side. The first doors 7 and 9 are housed inside the housing 2 from the second doors 8 and 10, and the material thereof is the same as the material of the inner wall surface of the housing 2. The aesthetic appearance inside the housing 2 is not impaired in the housed state. In the first embodiment, three doors are stored side by side, but the number of doors can be changed according to the size of the cooler box 1.

  Further, a finger hooking portion 7a1 is formed on the surface of the upper first door 7a. The finger hooking portion 7a1 is used by the user to swing the first door 7a toward the inside of the housing 2. Similarly, a finger hanger 7b1 is formed on the surface of the lower first door 7b, and a finger hanger 9a1 is formed on the surface of the first door 9.

  Further, the side wall 2d is formed with a cap housing portion 12 capable of housing the cap member 11 outside the housing 2 from the second doors 8 and 10. The cap member 11 is used to tightly seal the upper portion of a known paper pack 14 (container) (see FIG. 10) to seal the inside. As shown in the enlarged view, the cap member 11 is formed by a substantially U-shaped frame body in a top view, and the frame body has three portions from the upper part of the page to an end portion 11a, a narrow portion 11b, and an end portion 11c. It is composed of Projections 11d are formed on both side surfaces (the front side and the back side of the drawing) of the narrowed portion 11b of the cap member 11 along the longitudinal direction of the narrowing portion 11b (the projection 11d on the back side of the drawing is not shown). . In addition, concave concave portions 11a1 and 11c1 are formed on both sides of the end portion 11a and the end portion 11c, respectively (the concave portions 11a1 and 11c1 on the back side of the paper surface are not shown), and a concave shape is formed on the front side of the narrow portion 11b on the paper surface side. The recess 11b1 is formed. The recess 11b1 has a through-passage (not shown) whose inside penetrates to the end 11a side, and a fixing pin is provided from the recess 11b1 to the end 11a side at a position corresponding to the through-passage of the end 11a. An intrusion hole (not shown) through which the pin 15 intrudes when 15 (see FIG. 9) is inserted is formed.

  The known paper pack 14 is a gable top type paper pack filled with a liquid beverage such as milk or juice, and folds a polyethylene laminated paper in which a thin film made of polyethylene tree is bonded to water-resistant kraft paper. It is formed by heating and pressure bonding. Therefore, the upper portion of the paper pack 14 is folded in a gable roof shape, and the upper end portion thereof is bonded. Accordingly, once the upper end of the paper pack 14 is opened in order to pour out the liquid filled therein, the inside cannot be completely sealed even if the upper end of the opened one is folded.

  The cap housing portion 12 is a groove for housing the cap member 11, and the surface on the upper side of the side wall 2 d and the surface on the inside of the housing 2 are opened, and the inner shape of the groove is the outer shape of the cap member 11. The size is approximately the same. When the cap member 11 is stored in the cap storage portion 12, it is stored so that the U-shaped open end surface side (left side of the paper surface) is the inside of the housing 2.

  On both opposing end faces (end faces substantially parallel to the side walls 2b, 2c) of the cap housing portion 12, a slow insertion groove 12a into which the protrusion 11d of the cap member 11 is loosely inserted is formed. When the cap member 11 is housed in the cap housing portion 12, the protrusion 11d is loosely inserted into the loose insertion groove 12a, so that the cap member 11 can be prevented from being tilted and housed.

  Further, the opposite end surfaces of the cap housing portion 12 are formed with a convex portion 12b that fits into the concave portion 11a1 or the concave portion 11c1 when the cap member 11 is accommodated, and the concave portion 11a1 or the concave portion 11c1 and the convex portion. By fitting 12b, the cap member 11 can be prevented from jumping upward from the cap housing portion 12.

  Further, an insertion / removal groove 12c for improving the workability of inserting / removing the cap member 11 is formed at the upper end portions of the opposite end faces of the cap housing portion 12. Therefore, when the user pulls out the cap member 11, the user can insert a finger into the insertion / removal groove 12c and lift the cap member 11 from both sides.

  The cap storage portion 12 functions as an insertion portion into which either one of the end portions 11a and 11c is inserted when storing the paper pack 14 with the cap member 11 tightly attached. The description will be described later.

  Here, with reference to FIG.2 and FIG.3, the 1st door 9 and the 2nd door 10 which were accommodated in the side wall 2d of the housing | casing 2 are demonstrated.

It swings inwardly of the body 2 and opens to a position substantially parallel to the side wall 2c (see FIG. 1) (state of FIG. 3A). Next, the second door 10 is swung inwardly of the housing 2 and opened to a position substantially parallel to the side wall 2d (state shown in FIG. 3B). Further, when the first door 9 and the second door 10 are stored in the side wall 2d, the procedure opposite to the case of opening is performed, the second door 10 is swung in the direction of the first door 9, and then the first door This is performed by swinging the door 9 in the direction of the side wall 2d. In addition, the 1st door 9 and the 2nd door 10 are the position where the 1st door 9 and the 2nd door 10 were accommodated in the side wall 2d, and the position where the 1st door 9 and the 2nd door 10 rocked and opened. The details will be described later.

  Next, the first door 7, the second door 8, and the partition member 25 housed in the side wall 2d of the housing 2 will be described with reference to FIGS. FIG. 4 is an enlarged cross-sectional view showing an enlarged cross-section in the vertical direction of the side wall 2d in the IV-IV cross-sectional line shown in FIG. FIG. 5 is a view showing an appearance and a partial cross section of the second door 8, FIG. 5 (a) is an appearance view showing the appearance of the second door 8, and FIG. 5 (b) is a second view. 5 is a cross-sectional view showing a partial cross section of the door 8. FIG. FIG. 6 is an explanatory view showing a procedure for opening the first door 7 and the second door 8 and a procedure for swinging the partition member 25. FIGS. 6 (a) to 6 (f) show the first door 7. Each state of the second door 8 and the partition member 25 is shown.

  As described above, the first door 7 accommodated in the side wall 2d of the housing 2 is composed of the upper first door 7a and the lower first door 7b, and is formed on one end side like the first door 9. The connecting member 20 is inserted into the inserted through hole 21 (see FIG. 11), and is connected so as to be able to swing inward from the side wall 2d.

  Like the second door 10, the second door 8 is connected to the inner side of the housing 2 so as to be swingable from the upper first door 7 a by a connecting member 22 having two hinges. The second door 8 is also composed of an outer frame 8a and three pipes 8b, and an insertion portion 23 in which a convex portion 24 is disposed is formed at a substantially upper central portion of the outer frame 8a. In addition, this 2nd door 8 is comprised so that expansion-contraction in the up-down direction is demonstrated, and the structure is demonstrated below with reference to FIG.

  As shown in FIG. 5A, the outer frame 8a of the second door 8 is composed of an upper outer frame 8a1 and a lower outer frame 8a2, and the outer shape of the lower outer frame 8a2 is that of the upper outer frame 8a1. It is formed smaller than the inner shape, and its lower outer frame 8a2 is inserted into the hollow portion of the upper outer frame 8a1. Similarly, the pipe 8b of the second door 8 is composed of an upper pipe 8b1 and a lower pipe 8b2. The outer shape of the lower pipe 8b2 is smaller than the inner shape of the upper pipe 8b1, and the lower pipe 8b2 It is inserted into the hollow portion of the upper pipe 8b1.

  FIG. 5B is a cross-sectional view showing a cross section of a broken line A in FIG. 5A, and shows a structure in which the second door 8 is expanded and contracted. A projecting member 26 projecting inside the hollow portion is formed in the opening at the lower end of the upper outer frame 8a1. The protrusion member 26 is a protrusion for fixing the second door 8 in the extended state and the contracted state.

  The lower outer frame 8a2 is formed with a through hole 27 penetrating between the inner side and the outer side of the lower outer frame 8a2 in the vicinity of the upper end portion, and the inner side of the lower outer frame 8a2 in the vicinity of the lower end portion. A through hole 28 penetrating between the outside and the outside is formed.

  In the state of FIG. 5B, the protruding member 26 of the upper outer frame 8a1 is fitted in the through hole 27 formed in the vicinity of the upper end portion of the lower outer frame 8a2, and the second door 8 is fixed in an extended state. ing. The second door 8 in this state is approximately the same size as the first door 7. Further, when the second door 8 is contracted, it is performed by pushing up the lower outer frame 8a2. When the lower outer frame 8a2 starts to be pushed up, the projecting member 26 is removed from the inside of the through hole 27, the lower outer frame 8a2 moves upward in the hollow portion of the upper outer frame 8a1, and the lower pipe 8b2 is hollow in the upper pipe 8b1. The second door 8 contracts by moving the part upward. When the lower outer frame 8a2 is further pushed up, the protruding member 26 is fitted in the through hole 28 and the second door 8 is fixed in a contracted state. The second door 8 in this state is approximately the same size as the upper first door 7a.

  Here, returning to FIG. As shown in FIG. 4, the first door 7 and the second door 8 swing open from the second door 8 on the side wall 2d to the outer lower side of the housing 2 (below the cap housing portion 12). In this state, a plate-like partition member 25 that partitions the region formed by the first door and the second door into the bottom wall 2a side and the opening side is disposed. The partition member 25 is disposed in a disposition portion 30 formed of a substantially rectangular parallelepiped groove on the side wall 2d. The partition member 25 is arranged in the inner direction of the housing 2 by a rod member 31 whose both ends are fixed to grooves (not shown) formed in end faces substantially parallel to the side walls 2b, 2c in the arrangement portion 30. Is configured to be swingable. The partition member 25 is formed with a protruding portion 25a protruding upward while being accommodated in the side wall 2d, and the arrangement portion 30 is formed with a fitting portion 30a that fits the protruding portion 25a. .

  Therefore, when the partition member 25 swings from the side wall 2d to a position substantially parallel to the bottom wall 2a in the inner direction of the housing 2, the protruding portion 25a of the partition member 25 is the fitting portion 30a of the arrangement portion 30. And the partition member 25 is held at a position substantially parallel to the bottom wall 2a. In addition, when the partition member 25 is swung, the lower surface of the partition member 25 is substantially equal to the lower end surface of the upper first door 7a in the substantially vertical direction of the bottom wall 2a.

  Since the partition member 25 is held in a state of swinging so as to be substantially parallel to the bottom wall 2a, the partition member 25 is placed in a storage region X (see FIG. 7) formed by swinging the first door 7 and the second door 8. When the paper pack 14 is stored, the bottom surface of the paper pack 14 can be supported by the top surface of the partition member 25. In other words, the depth of the storage region X can be formed in two different depths: a depth when the partition member 25 is stored in the side wall 2d and a depth when the partition member 25 is swung. In the first embodiment, the depth of the state in which the partition member 25 is housed in the side wall 2d (the depth of the housing 2) is "paper pack 14 filled with" 1000 milliliters (hereinafter referred to as "ml") ". The depth of the state in which the partition member 25 is swung is substantially the same as the height of the paper pack 14 filled with “500 ml”. The height of the paper pack 14 varies from about 1 millimeter (hereinafter referred to as “mm”) to about 6 mm depending on the shape. In this embodiment, various adjustments are made corresponding to the highest paper pack 14. Yes. Further, since the difference in height of the paper pack 14 is several mm, there is no problem that it becomes difficult to store and take out the paper pack 14.

  When the “1000 ml” paper pack 14 is stored, the same procedure as the first door 9 and the second door 10 described above is performed. That is, the user puts his finger on the finger rest 7a1 and swings the upper first door 7a inward of the housing 2 so as to be substantially parallel to the side wall 2c. At this time, the lower first door 7b is also pushed by the second door 8 and swings in conjunction therewith. Thereafter, the second door 8 is swung inwardly of the housing 2 and opened so as to be substantially parallel to the side wall 2d, thereby forming an area capable of storing the “1000 ml” paper pack 14. When the first door 7 and the second door 8 are stored in the side wall 2d, the second door 8 is swung in the direction of the first door 7, and the upper first door 7a and the lower second door 7b are moved. This is done by swinging in the direction of the side wall 2d.

  Here, with reference to FIG. 6, a procedure for opening the first door 7 and the second door 8 and a procedure for swinging the partition member 26 when storing the paper pack 14 for “500 ml” will be described.

  When storing the “500 ml” paper pack 14, first, the user puts his finger on the finger rest 7 b 1 and swings the lower first door 7 b inwardly of the housing 2 so as to be substantially parallel to the side wall 2 c. Open to the position (state shown in FIG. 6A). Next, when the lower outer frame 8a2 of the second door 8 is pushed up in the direction of arrow B shown in FIG. 6A, as described above, the protruding portion 26 of the upper outer frame 8a1 becomes the through hole 28 of the lower outer frame 8a2. And is fixed at a size substantially equal to that of the upper first door 7a. (State of FIG. 6B). From this state, similarly to the swinging procedure of the first door 9 and the second door 10 described above, the upper first door 7a is swung in the inner direction of the housing 2 (in the direction of arrow C in the figure) and substantially the same as the side wall 2c. It opens so as to be parallel (state shown in FIG. 6C), and the second door 8 swings inwardly of the housing 2 (in the direction of arrow D in the figure) and opens so as to be substantially parallel to the side wall 2d (FIG. 6 ( d) state). Then, the partition member 25 is swung to a position substantially parallel to the bottom wall 2a in the inner direction of the housing 2 (in the direction of arrow E in the figure) (state shown in FIG. 6E), and the lower first door 7b is moved. Swing in the direction of the side wall 2d (in the direction of arrow F in the figure), the lower first door 7b is stored in the side wall 2d (the state shown in FIG. 6 (f)), and the paper pack 14 for "500ml" can be stored. A region is formed.

  When the first door 7 and the second door 8 are stored in the side wall 2d, first, the lower first door 7b is opened so as to be substantially parallel to the side wall 2c, and the partition member 25 is swung in the side wall 2d direction. And stored in the side wall 2d. Thereafter, the second door 8 in a contracted state is extended to swing toward the first door 7, and the upper first door 7a and the lower first door 7b are swinged toward the side wall 2d for storage. .

  In addition, the first door 7 and the second door 8 are also in a position where the first door 7 and the second door 8 are stored in the side wall 2d, and a position where the first door 7 and the second door 8 are swung open. The details will be described later.

  Here, a state in which the first doors 7 and 9 and the second doors 8 and 10 are opened by the above-described swinging procedure will be described with reference to FIG. FIG. 7 is a partial perspective view showing a state in which each door accommodated in the side wall 2d is opened. In addition, the 1st door 7 and the 2nd door 8 have shown the case where it adjusts to the magnitude | size corresponding to the paper pack 14 for "500 ml".

  As illustrated, the storage area X of the first door 7 and the second door 8 is adjusted so that the “500 ml” paper pack 14 is stored. The storage area X is composed of four surfaces: an upper first door 7a, a second door 8, and side walls 2c and 2d (first side wall and second side wall). Also, the first door 9 and the second door 10 on the right side of the page are the first door 9, the second door 10, the side wall 2d, and the upper first door 7a (the first door adjacent to the second side wall). The storage area Y of the paper pack 14 is configured by four surfaces, and the first door 9 and the second door 10 on the right side of the paper surface are the four surfaces of the first door 9 and the second door 10 and the side wall 2d. A storage area Y for the paper pack 14 is configured.

  When the paper packs 14 are stored in the storage areas X and Y, the second doors 8 and 10 are configured by joining the three pipes 8b and 10b to the outer frames 8a and 10a. The front and back sides of the 8th and 10th are in communication. That is, since the storage section of the housing 2 and the storage areas X and Y of the paper pack 14 are in communication with each other, the cooling and heating action can be efficiently performed on the stored paper pack 14.

  Further, when the number of paper packs 14 to be stored is small, the first doors 7 and 9 and the second doors 8 and 10 are swung from the side wall 2c side in accordance with the number of the paper packs 14 and are not used. Since the door can be stored in the side wall 2d, the storage portion of the housing 2 can be used effectively. Further, when storing the “500 ml” paper pack 14, the upper end portion of the “500 ml” paper pack 14 is positioned substantially equal to the opening of the housing 2 by swinging the partition member 25. Therefore, it is possible to prevent the paper pack 14 from being difficult to be taken out. Furthermore, since the area Z below the partition member 25 can be used as a storage unit for the housing 2 and can store other foodstuffs, the storage unit of the housing 2 can be used more effectively. be able to.

  Next, with reference to FIG. 8 and FIG. 9, the structure of the cap member 11 and the procedure for tightly attaching the upper end of the paper pack 14 will be described. FIG. 8 is an enlarged perspective view of the cap member 11. FIG. 9 is an explanatory view showing a procedure in which the cap member 11 narrows the upper end portion of the paper pack 14, and FIGS. 9A to 9C show each state of the cap member 11. . Note that the paper pack 14 shown in FIG. 9 is a paper pack 14 that is once opened to pour out the liquid filled therein.

  As described above, the cap member 11 is composed of the three portions of the end portion 11a, the narrow portion 11b, and the end portion 11c, and the upper portion of the paper pack 14 is tightly sealed to seal the inside of the paper pack 14. Is for. The cap member 11 is a frame formed of opposed side surfaces and an upper surface and formed in a substantially U shape in a cross-sectional view, and is formed of a synthetic resin material such as a polycarbonate resin having excellent impact resistance and mechanical strength. ing.

  As shown in FIG. 8, the cap member 11 has one end side of the end portion 11c and the narrow portion 11b coupled to each other by a hinge member 40 so as to be swingable, and the end portion 11a and the narrow portion are connected to the end portion 11c. 11b integrally swings from the front side to the back side. The narrowing portion 11b is configured such that a swinging portion 43 having an upper surface and the other side surface with respect to one side surface can swing in a vertical direction on the paper surface by a hinge member (not shown). In addition, on the inner wall surfaces of the opposing side surfaces of the cap member 11, sealing auxiliary members 41 that protrude in order to improve the sealing force of the paper pack 14 are formed in two upper and lower rows. The sealing auxiliary member 41 is formed in a substantially triangular cross-section paper, and the sealing force is improved by pressing the upper end of the paper pack 14 at the apex of the triangle.

  As shown in FIG. 9, when the cap member 11 is tightly attached to the paper pack 14, first, the end portion 11c of the cap member 11 is inserted into the upper end portion 42a of the paper pack 14 which is not opened (FIG. 9). (State of (a)). When the end portion 11c of the cap member 11 is inserted into the upper end portion 42a of the paper pack 14, the upper end portion 42a is narrowed by the end portion 11c and the cap member 11 is fixed, thereby improving the workability of the subsequent narrowing operation. can do.

  When the end portion 11c is inserted into the upper end portion 42a, the end portion 11a and the narrowed portion 11b are moved from the back side to the front side, and one side surface of the narrowed portion 11b and the upper end portions 14a1 and 14a2 that are the back side of the paper surface. It swings so as to come into contact (the state shown in FIG. 9B). Thereafter, the swinging portion 43 is moved from the upper side to the lower side of the paper, and the other side surface of the swinging portion 43 and the upper end portions 42a and 42b which are the front of the paper. Rocks so as to come into contact with each other (the state shown in FIG. 9C). In the state of FIG. 9C, the narrow pinion portion 11b is fixed by pushing the fixing pin 15 into the concave portion 11b1 in the direction of arrow G in the drawing to the insertion end portion 11a side, and the cap member 11 is attached to the paper pack 14. It is narrowly worn. In the state where the cap member 11 is tightly attached to the paper pack 14, the upper end portions 42a and 42b are pressed by the sealing auxiliary member 41, so that the inside of the paper pack 14 can be sealed, and the paper pack 14 tilts or falls. Even when the liquid is swayed up and down, the liquid filled therein can be prevented from flowing out from the opened upper end portion 42b.

  Next, with reference to FIG. 10, a procedure for storing the paper pack 14 with the cap member 11 tightly attached in the storage areas X and Y (see FIG. 7) formed by swinging the doors will be described. To do. FIG. 10 is an explanatory view showing a state in which the paper pack 14 with the cap member 11 tightly attached is stored in the storage area X. FIG. The procedure for storing the paper pack 14 in the storage area Y formed by the first door 9 and the second door 10 is to store the paper pack 14 in the storage area X formed by the first door 7 and the second door 8. Since it is the same as the procedure to perform, the description thereof is omitted.

  As shown in the drawing, the cap member 11 is tightly attached to the upper end portions 42 a and 42 b of the paper pack 14, and the inside of the paper pack 14 is sealed by the cap member 11. Since the cap member 11 is formed longer than the distance between the side wall 2b and the second door 8 in a state where the first door 7 and the second door 8 swing and open, the upper end portion 42a of the paper pack 14 is formed. It protrudes outward from 42b.

  The end 11a of the cap member 11 is inserted into the insertion portion 23 of the second door 8, and the concave portion 11a1 (see FIG. 8) of the end portion 11a and the convex portion 24 (see FIG. 7) of the insertion portion 23 are fitted. At the same time, the end portion 11c of the cap member 11 is inserted into the cap storage portion 12 of the side wall 2d, and the concave portion 11c1 (see FIG. 8) of the end portion 11c and the convex portion 12d (see FIG. 1) of the cap storage portion 12 are fitted. In combination, the cap member 11 is fixed between the insertion portion 23 and the cap storage portion 12. Therefore, even if the cooler box 1 is carried and shaken, the paper pack 14 can be reliably prevented from being tilted or tilted. Moreover, since this cap accommodating part 12 inserts and fixes the edge part 11c of the cap member 11, it not only accommodates the cap member 11, but has the effect | action of an insertion part similar to the insertion part 23 of the 2nd door 8. FIG.

  In the first embodiment, the paper pack 14 with the cap member 11 tightly attached is stored in the storage area X. However, the cap member 11 is stored with the paper pack 14 stored in the storage area X. It is good also as what is narrowly worn. In this case, when the end portions 11 a and 11 c of the cap member 11 are inserted into the insertion portion 23 of the second door 8 and the cap storage portion 12, the end portion 14 c is closely attached to the upper end portion 42 a of the paper pack 14. Thereafter, the swinging portion 43 is swung so that the cap member 11 is tightly attached to the upper end portions 42 a and 42 b of the paper pack 14.

It is also possible to insert the end portion 11 c into the cap housing portion 12 and insert the end portion 11 a into the cap housing portion 12.

  Here, referring to FIG. 11, first doors 7 and 9 and second doors 8 and 10 are fixed to the positions where the doors are housed in side wall 2d and the positions where the doors swing and are opened. The structure for doing this will be described. FIG. 11 is an explanatory view showing a structure for fixing the first doors 7 and 9 and the second doors 8 and 10, respectively. FIG. 11A is a perspective view showing a structure for fixing the first doors 7 and 9 (only the upper first door 7a in the first door 7), and FIG. It is the figure which showed the structure for fixing the 1st doors 7 and 9 (only the lower 1st door 7b in the 1st door 7) and the 2nd doors 8 and 10. FIG. FIG. 11C is a perspective view showing a structure for fixing the first doors 8 and 10 at positions substantially perpendicular to the first doors 7 and 9. In the following description, the first door 7 and the second door 8 will be described, and the first door 9 and the second door 10 have the same structure, and the description thereof will be omitted.

  FIG. 11A is an enlarged perspective view showing the upper end portion of the upper first door 7a, in which the connecting member 20 is omitted. The end surface 50 that is the front of the paper surface is a surface that faces the side wall 2d when the upper first door 7a swings and opens, and the right side of the paper surface is the side wall when the upper first door 7a is stored in the side wall 2d. This is an end face 51 facing 2d.

  Further, as shown in the drawing, a fixing groove 52 having a substantially L shape in top view is formed at the upper end portion of the upper first door 7a so that the connecting member 20 fits in and fixes the swinging position of the upper first door 7a. One end side of the fixing groove 52 extends to the end surface 50 side, and the other end side extends to the end surface 51 side. A portion 53 surrounded by the fixing groove 52 in the upper end portion of the upper first door 7a is lower than the upper end surface of the upper first door 7a and is further tapered. Therefore, even when the upper first door 7a swings, the resistance by the portion 53 is small, and the operation can be performed smoothly.

  In a state where the upper first door 7a is housed in the side wall 2d, the connecting member 20 is fitted and fixed in a fixing groove 52 extending from the insertion hole 21 to the end surface 51. Further, in a state where the upper first door 7a swings and opens at a position substantially parallel to the side wall 2c, the connecting member 20 is fitted and fixed in a fixing groove 52 extending from the insertion hole 21 to the end surface 50.

  FIG. 11B is an enlarged view of the lower ends of the lower first door 7b and the second door 8, and the lower ends of the lower first door 7b and the second door 8 are the lower side. In the 1st door 7b, it is a lower end part of the other end side opposite to the one end side connected by the connection member 20, and in the 2nd door 8, it is opposite to the one end side connected with the upper side 1st door 7a by the connection member 22. It is the lower end part of the other end side used as the side.

  As shown in FIG. 11 (b), the lower first door 7a and the lower door 8 are provided at the lower ends thereof with the positions where the lower first door 7a and the second door 8 are housed in the side wall 2d. A fixing member 55 for fixing the door at a position where the door swings open is attached. The fixing member 55 is provided with an elastic member 57 formed of a coil spring or the like in a cylindrical cylindrical groove 56 formed at the lower end of the other end of each door, and a substantially hemispherical shape at the opening of the cylindrical groove 56. The hemispherical member 58 is fixed and configured. The hemispherical member 58 is pressed downward and protrudes by the elastic force of the elastic member 57, and is configured to fit into the cylindrical groove 56 when pressed upward. That is, it can be expanded and contracted in the direction of arrow H in the figure.

  In the bottom wall 2a of the housing 2, the lower first door 7b and the second door 8 swing and open, and the lower first door 7b and the second door 8 are stored in the side wall 2d. A hemispherical hemispherical groove (not shown) having a diameter substantially equal to the diameter of the hemispherical member 58 is formed at the position. Since the hemispherical groove has a tapered outer periphery, the hemispherical member 58 can be smoothly moved in and out. When the lower first door 7b and the second door 8 are in the above-described two positions, the hemispherical member 58 is pressed by the elastic member 57 and protrudes outward to fit into the hemispherical groove, and the lower first door 7b. And the second door 8 are fixed respectively. When the lower first door 7b and the second door 8 are swung, the hemispherical member 58 is pushed into the bottom wall 2a and enters the cylindrical groove 56, thereby enabling a swinging operation.

  As described above, the second door 8 is biased to a position substantially parallel to the first door 7 by the connecting member 22 and is biased to a position substantially perpendicular to the first door 7. Since the operation is stopped, the fixing member 55 corresponding to the second door 8 and the fixing groove may be omitted.

  Further, as shown in FIG. 11 (c-1), the second door 8 is provided with a protruding portion 59 that protrudes outward, and the first door 7 is formed with a notch that is approximately the same size as the protruding portion 59. It is good also as what adds the structure which provides the fitting part 60, forms the protrusion 61 in the notch fitting part 60, and forms the groove | channel 62 in which the protrusion 61 fits in the protrusion part 59. FIG. In this structure, when the 2nd door 8 is rock | fluctuated, since the protrusion part 59 and the fitting part 60 fit (state of FIG.11 (c-2)), the 2nd door 8 is made into the 1st door 7. It can be firmly fixed at a position that is substantially perpendicular to the angle.

  As described above, the cooler box 1 of the first embodiment swings the first doors 7 and 9 so as to be substantially parallel to the side wall 2c, and makes the second doors 8 and 10 substantially parallel to the side wall 2d. By swinging in such a manner, storage areas X and Y in which the paper pack 14 can be stored can be formed. Moreover, it swings and opens by the fixing groove 52 formed in the upper ends of the first doors 7 and 9 and the fixing member 55 formed in the lower ends of the first doors 7 and 9 and the second doors 8 and 10. Since each door can be fixed at the closed position, it is possible to reliably prevent the paper pack 14 from tilting or falling. When the paper pack 14 is not stored, the first doors 7 and 9 and the second doors 8 and 10 can be stored in the side wall 2d, so that the storage area of the storage unit of the housing 2 can be used effectively.

  Next, with reference to FIG. 12, the cooler box 1 of 2nd Example is demonstrated. FIG. 12 is a partial perspective view showing a state in which each door housed in the side wall 2d of the cooler box 1 of the second embodiment is opened. In addition, the same code | symbol is attached | subjected to the part same as 1st Example, and the description is abbreviate | omitted.

  In the cooler box 1 of the second embodiment, all the doors housed in the side wall 2d are divided vertically. The first door 107 is divided into upper and lower first doors 107a and 107b, and the second door 108 is configured to be extendable in the vertical direction. The upper first door 107a is formed with a finger hanging portion 107a1, and the lower first door 107b is formed with a finger hanging portion 107b1. In FIG. 12, the paper pack 14 for “1000 ml” can be stored on the side wall 2 c side, and the other is adjusted so that the paper pack 14 for “500 ml” can be stored.

  Therefore, in the cooler box 1 of the second embodiment, each door is configured to be capable of storing “1000 ml” and “500 ml” paper packs 14. It can correspond to. Further, as in the first embodiment, the first door 107 and the second door 108 can be stored in the side wall 2d, and each door can be fixed in a state where it swings and is opened by the fixing groove 52 and the fixing member 55. The effect that the storage part of the housing | casing 2 can be used effectively and the effect which can prevent the inclination and the fall of the paper pack 14 are produced.

  Next, a third embodiment will be described with reference to FIGS. FIG. 13 is a perspective view showing an outline of the appearance of the cooler box 1 of the third embodiment, and FIG. 14 is an enlarged view of a vertical section of the side wall 2d taken along the line V-V shown in FIG. 15 is an enlarged cross-sectional view, and FIG. 15 is an enlarged cross-sectional view showing an enlarged vertical cross section of the side wall 2d in the VI-VI cross-section line shown in FIG. FIG. 17 is an enlarged perspective view showing the communication groove 279 in an enlarged manner, and FIG. 17 is a partial perspective view showing a state in which each door housed in the side wall 2d is opened. FIG. 18A is an enlarged view of a portion indicated by an arrow h in FIG. 7, and FIG. 18B is a cross-sectional view taken along a cross-sectional line VII-VII in FIG. In addition, the same code | symbol is attached | subjected to the part same as 1st Example, and the description is abbreviate | omitted.

  As shown in FIG. 13, the cooler box 1 of the third embodiment is configured such that the housing portion of the housing 2 is deeper than the cooler box 1 of the first embodiment. Therefore, there is an area where foodstuffs and the like can be stored below each door stored in the door storage unit 15.

  As in the first embodiment, a plurality of doors formed in a plate shape are stored side by side in the door storage portion 15 of the side wall 2d, and the upper first door 207a and the lower first door are disposed on the side wall 2c side. A first door 207 and a second door 208 which are divided into upper and lower parts of 207b are connected and stored, and the first door 209 and the second door are disposed on the side wall 2b side of the first door 207 and the second door 208. 210 is connected and stored, and the first door 209 and the second door 210 are connected and stored on the side wall 2d side. In addition, a finger hook portion 207a1 is formed on the surface of the upper first door 207a (the surface on the inside of the housing 2), and a finger hook portion 207b1 is formed on the surface of the lower first door 720b. A finger hook 209a1 is formed on the surface.

  Here, with reference to FIG. 14, a cross section in the vertical direction of the side wall 2d in the VV cross section line shown in FIG. 13 will be described. As shown in the figure, a side wall protruding member 270 that protrudes substantially horizontally with respect to the bottom wall 2a (see FIG. 13) in the inner side direction (the left side of the drawing) of the housing 2 is connected to the lower end portion of the door storage portion 15. In addition, a door protrusion member 272 that protrudes substantially horizontally with respect to the bottom wall 2a in the inner direction of the housing 2 is continuously provided at the lower end portion of the outer frame 210a of the second door 210 (the lower end portion of the second door 210). Has been. Therefore, when the first door 209 and the second door 210 swing and open to form the storage area Y (see FIG. 17), the side wall protrusion member 270 and the door protrusion member inward of the storage area Y. 272 face each other and protrude. Therefore, when the paper pack 14 is stored in the storage area Y, the bottom surface of the paper pack 14 is in contact with the side wall protruding member 270 and the door protruding member 272 so that the paper pack 14 can be supported and stored.

  Further, a second cutout portion 271 that can accommodate the side wall protruding member 270 at the lower end portion of the outer frame 210 a of the second door 210 in a state where the first door 209 and the second door 210 are accommodated in the door accommodating portion 15. Is formed. The second notch 271 has an opening in which a surface facing the side wall 2d of the outer frame 210a formed in a hollow shape is cut out and extends from the opening to a side surface facing the outer frame 210a. An area in which the member 270 can be stored is formed. That is, the second notch 271 is formed such that the length in the thickness direction of the second door 210 is substantially equal to the thickness of the second door 210. Further, as shown in the drawing, the side wall projection member 270 is formed to have a size that is substantially the same as that of the second cutout portion 271, and is formed to have a size that is substantially maximum with respect to the thickness of the second door 210.

  At the lower end of the first door 209, a first notch 273 capable of accommodating the door protrusion member 272 in a state where the first door 209 and the second door 210 are accommodated in the door accommodating portion 15 is provided in the first door. It is formed so as to penetrate the front and back surfaces of 209. That is, the first cutout portion 273 is formed so that the length in the thickness direction of the first door 209 is substantially equal to that of the first door 209. Further, as shown in the figure, the door protrusion member 272 is formed with a size that is substantially the same as that of the first cutout portion 273, and is formed with a size that is substantially maximum with respect to the thickness of the first door 209.

  Therefore, the side wall projection member 270 and the door projection member 272 are securely stored by the first cutout portion 273 and the second cutout portion 271 in a state where the first door 209 and the second door 210 are stored in the door storage portion 15. Therefore, it is not necessary to form a region for accommodating the side wall protruding member 270 and the door protruding member 272 in the door storing portion 15, and the size is substantially the same as that of the door storing portion 15 shown in the first embodiment. can do. Therefore, even in the structure including the side wall protrusion member 270 and the door protrusion member 272, the door storage portion 15 does not need to be formed large, and the side wall 2d can be prevented from becoming thick. Therefore, it is possible to prevent problems such as the effective use of the storage area and the increase in the size of the cooler box 1 itself.

  Furthermore, since the side wall projection member 270 and the door projection member 272 are formed to have a size that is substantially the maximum with respect to the thickness of the first door 209 and the second door 210, the paper pack 14 is stored in the storage area Y. In this case, the side wall protruding member 270 and the door protruding member 272 can securely support and store the bottom surface of the paper pack 14 and prevent the paper pack 14 from falling in the direction of the bottom wall 2a.

  Next, a cross section in the vertical direction of the side wall 2d taken along the line VI-VI shown in FIG. 13 will be described with reference to FIGS. As shown in the figure, a movement range is formed on the side wall 2d as the lower end of the door storage portion 15 to form a movement range of a side wall protruding member 275 that can move in a substantially vertical direction with respect to the bottom wall 2a (see FIG. 13). A portion 276 is recessed. A support member 277 that protrudes from both side end portions of the side wall protruding member 275 and has a substantially square-shaped support member 277 is inserted into both opposing side surfaces (only the side surface that is the back side of the drawing) of the movement range forming portion 276. Grooves 278 are formed at two locations, upper and lower, and the two support grooves 278 are communicated with each other by a communication groove 279. FIG. 15 shows a state in which the support member 277 is inserted into the support groove 278 on the lower side of the paper, and this state corresponds to the paper pack 14 for “1000 ml”. When the support member 277 is inserted into the support groove 278 on the upper side of the paper surface, the position corresponds to the paper pack 14 for “500 ml”.

  Since the support groove 278 is formed in a substantially quadrangular sectional view having an inner shape substantially equivalent to the outer shape of the support member 277, the side wall protrusion member 275 is bottomed in a state where the support member 277 is fitted into the support groove 278. Swinging in the direction of the wall 2a is prohibited.

  The communication groove 279 includes a vertical groove 279a formed on the second door 208 side (left side of the paper surface) of the moving range forming portion 276 so as to extend vertically in a direction substantially perpendicular to the bottom wall 2a, and both upper and lower sides of the vertical groove 279a. And a horizontal groove 279b extending substantially horizontally with respect to the bottom wall 2a in the outward direction of the housing 2 (the right side of the drawing), and the horizontal groove 279b and the support groove 278 communicate with each other.

  The communication groove 279 is formed larger than the outer shape of the support member 277, and the movement of the support member 277 via the communication groove 279 can be performed smoothly. Further, since the upper and lower support grooves 278 can be moved via the communication groove 279, the support member 277 is removed from the support groove 278 every time the side wall protrusion member 275 is moved, and the support member 277 is changed to the support groove 278 again. There is no need for complicated work such as insertion, and the work procedure can be reduced.

  An auxiliary plate 280 is disposed adjacent to the lower end surface of the support groove 278 in the movement range forming portion 276 of the third embodiment. The auxiliary plate 280 is in contact with the lower surface of the side wall projection member 275, and when the paper pack 14 is stored and a load is applied to the side wall projection member 275, the side wall projection member 275 is prohibited from swinging toward the bottom wall 2a. It is a plate-shaped member for assisting. The auxiliary plate 280 is provided at two locations, upper and lower, corresponding to the support groove 278. As shown in FIG. 16, the auxiliary plate 280 is constituted by a block piece. However, in order to reliably assist the prohibition of the swinging of the side wall projection member 275, the auxiliary plate 280 is moved to the moving range forming portion 276. It is good also as what forms over between the opposing side surfaces. On the other hand, the auxiliary plate 280 may be omitted as long as the support groove 278 and the support member 277 can prevent the side wall protruding member 275 from swinging in the direction of the bottom wall 2a.

  Returning to FIG. Similar to the lower end portion of the second door 210, the lower end portion of the second door 208 includes a second cutout portion 281 that can accommodate the side wall protruding member 275, and a door protruding member 282 that protrudes inward of the housing 2. Is formed. In addition, a first notch portion 283 capable of accommodating the door protrusion member 282 is formed at the lower end portion of the lower first door 207b, similarly to the lower end portion of the first door 209.

  The upper first door 207a has a third notch 284 formed in the same shape as the first notch 283 of the lower first door 207b. The third notch 284 is formed at a position corresponding to the position of the door protrusion member 282 when the second door 208 is contracted so as to be approximately the same size as the upper first door 207a.

  Therefore, by forming the third notch 284, the second door 208 and the side wall protruding member 275 are adjusted to the position corresponding to the “500 ml” paper pack 14, and the first door 207 and The second door 208 can be stored in the door storage unit 15, and it is not necessary to adjust the second door 208 and the side wall protruding member 275 every time the “500 ml” paper pack 14 is stored. Further, since the first door 207 and the second door 208 can be stored in the door storage unit 15 in a state adjusted to the “500 ml” paper pack 14, the lower first door 207 b can be stored without swinging. Region X (see FIG. 17) can be formed. Accordingly, it is possible to reduce the work procedure for forming the storage area X for storing the “500 ml” paper pack 14. As in the first and second embodiments, in the state where the lower first door 207b is stored in the door storage unit 15, the storage unit of the housing 2 can be further widened, and the storage area can be used effectively. Can do.

  Next, a state where the first doors 207 and 209 and the second doors 208 and 210 are swung open will be described with reference to FIGS. The second door 208 and the side wall projection member 275 are adjusted to correspond to the “500 ml” paper pack 14, and the lower first door 207 b is stored in the door storage unit 15. Yes.

  As shown in FIG. 17, when the first doors 207, 209 and the second doors 208, 210 are opened by swinging, the end surfaces of the first doors 207, 209 on the side wall 2 c side, and the second door 208. , 210 are in contact with the end surface on the side wall 2b side. That is, unlike the doors of the first and second embodiments, the second doors 208 and 210 open only to a position that is substantially perpendicular to the first doors 207 and 209 in a state where the doors swing. It is configured as follows.

  Furthermore, in a state where the first doors 207 and 209 and the second doors 208 and 210 are swung open, the end surface on the side wall 2c side of the second door 210 is the first door 209 adjacent to the side wall 2c side or The end surface on the side wall 2b side of the first door 207 is in contact with the side surface 2c side, and the end surface on the side wall 2c side of the second door 208 is in contact with the side wall 2c. Note that the contact surfaces (adhering portions) between the first doors 207 and 209 or the side wall 2c and the second doors 208 and 210 are firmly fixed to each other. This contact surface will be described below with reference to FIG.

  As shown in FIG. 18A, the contact surface between the first door 209 and the second door 210 is in the direction of the finger hooking portion (fitting groove) 209a1 of the first door 209 and the side wall 2c of the second door 210. It is comprised by the fitting part 285 which protruded in the convex shape. As shown in the cross-sectional view of FIG. 18B, the fitting portion 285 extends from the end surface on the inner side of the housing 2 of the second door 210 (the lower side in FIG. 18B) to the first door 209. It is formed in a smooth curved surface that curves in the direction of the side wall 2d (upward on the paper surface) from the extended tip. The side wall 2c is formed with a fitting groove (not shown) having a size substantially equal to that of the finger hooking portion 209a1 corresponding to the fitting portion 285 formed on the second door 208.

  Therefore, when the first doors 207 and 209 and the second doors 208 and 210 swing and are opened, the fitting portion 285 is fitted and fixed to the finger-hanging portions 207a1 and 209a1. It is possible to reliably prevent the second doors 208 and 210 from being pushed and moved in the direction of the side wall 2d due to stored foods or the like. In addition, since the fitting portion 285 is curved in the direction of the side wall 2d and is formed with a smooth curved surface, the fitting portion 285 can be smoothly attached to and detached from the finger hook portion 209a1. Note that the fitting groove into which the fitting part 285 is fitted uses the finger hooking part 209a1, so that it is not necessary to form a new fitting groove and the manufacturing cost can be reduced.

  As described above, the cooler box 1 of the third embodiment supports the bottom surface of the paper pack 14 stored in the storage areas X and Y by the side wall protruding members 270 and 275 and the door protruding members 272 and 282. Therefore, the space below each door can be used as an area for storing food items and the like, and the storage area inside the housing 2 can be used effectively.

  Further, since the side wall protruding members 270 and 275 and the door protruding members 272 and 282 are formed with a size that is substantially maximum with respect to the thickness of each door, the bottom wall of the paper pack 14 can be reliably supported. It is possible to prevent the paper pack 14 from falling in the direction of the bottom wall 2a.

  Of course, the cooler box 1 of the third embodiment may have a structure corresponding to the paper packs 14 of “500 ml” and “1000 ml” as in the cooler box 1 of the second embodiment. .

  Next, with reference to FIG. 19, another structure for fixing the second doors 208 and 210 and the first doors 207 and 209 or the side wall 2c to each other will be described. FIG. 19 is an enlarged perspective view showing the contact surface (adhering portion) between the first door 209 and the second door 210.

  The abutting surface shown in FIG. 19A is provided with a substantially mushroom-shaped stopper 290a provided continuously with the first door 209, a substantially mushroom-shaped stopper 290b provided with the second door 210, and the stopper 290a. , 290b, and a clip member 291. The first door 209 and the second door 210 are fixed by applying both ends of the clip member 291 to the stoppers 290a and 290b. Note that one end of both ends of the clip member 291 may be configured to be rotatably connected to one of the stoppers 290a and 290b.

  The contact surface shown in FIG. 19B penetrates the through hole 292a formed through the first door 209, the through hole 292b formed through the second door 210, and the through holes 292a and 292b. It is comprised by the substantially U-shaped penetration member 293 inserted. The penetrating member 293 is formed so that both substantially U-shaped tip portions are inclined inwardly, so that the penetrating member 293 can be easily removed in a state where the penetrating member 293 is inserted into the through holes 292a and 292b. Can be prevented.

  The contact surface shown in FIG. 19C is provided with an opening 294 formed on the end surface of the first door 209 on the second door 210 side, and is disposed on the second door 210 and swings in the direction of the first door 209. And a swing member 295. The swing member 295 is disposed in the outer frame 210a of the second door 210, and is connected to the rotary handle 295a on the front surface, the rotary shaft 295b pivotally attached to the handle 295a, and the rotary shaft 295b. And a latching portion 295c. By rotating the handle 295a counterclockwise, the latching portion 295c rotates in the direction of the first door 209 and the tip is latched on the opening 294, so that the first door 209 and the second door 210 are fixed.

  In addition, referring to FIG. 20, a structure that allows the second door 208 and the side wall projection member 275 to be adjusted in multiple stages in a substantially vertical direction with respect to the bottom wall 2a will be described. 20A is a perspective view showing the support groove 278 and the communication groove 289 of the moving range forming portion 276, and FIG. 20B is a cross section showing a cross section of the outer frame 208a of the second door 208. FIG.

  As shown in FIG. 20A, a plurality of support grooves 278 are formed on both opposing side walls (only one side wall is shown) of the movement range forming portion 276 in a direction substantially perpendicular to the bottom wall 2 a of the housing 2. The plurality of support grooves 278 are formed and communicated with each other by a communication groove 279 having a horizontal groove 279b and a vertical groove 279a. Therefore, the depth of the storage region X can be adjusted by the support member 277 moving through the communication groove 279 and being inserted into any one of the support grooves 278. 20A shows the case where the number of the support grooves 278 is eight, the number is changed according to the size of the paper pack 14 to be stored and the depth of the housing 2. It is also good. Further, the auxiliary plate 280 may be disposed corresponding to each support groove 278.

  As shown in FIG. 20B, the outer frame 208a2 on the lower side of the second door 208 is formed with a plurality of through holes 296 into which the projections 26 are fitted in a substantially vertical direction of the bottom wall 2a. . When the outer frame 208a2 is expanded and contracted, the protrusion 26 is fitted into any of the through holes 296, and the depth of the storage region X can be adjusted. The through holes 296 are formed so as to correspond to the plurality of support grooves 278 described above, and eight through holes 296 are formed.

  Accordingly, a plurality of support grooves 278 are formed on opposite side walls of the movement range forming portion 276, and a plurality of through holes 296 are formed in the outer frame 208a2 on the lower side of the second door 208, whereby the housing 2 The distance from the opening to the door protrusion member 282 and the side wall protrusion member 275 can be adjusted in multiple stages according to the size (height) of the paper pack 14. Accordingly, the difference in height between the upper end portion of the paper pack 14 and the opening of the housing 2 is reduced, so that it is possible to prevent the paper pack 14 and the like from being difficult to be taken out.

  Furthermore, with reference to FIG. 21, the other structure of the door projection members 272 and 282 and the side wall projection members 270 and 275 will be described. In addition, the structure of the door projection member 272 attached to the lower end part of the 2nd door 210 is demonstrated, and the description is abbreviate | omitted about the attachment structure of the other door projection member 282 and the side wall projection members 270 and 275. FIG. 21 is an enlarged cross-sectional view showing an enlarged cross section of the door protrusion member 272 portion attached to the lower end portion of the second door 210.

  The structure for attaching the door projection member 272 to the lower end portion of the second door 210 is that the concave groove portion 300 formed in the second door 210, the plate-like door plate member 301, and the door plate member 301 are swung. The swing coupling portion 302 that can be coupled to the groove portion 300 and the door plate member 301 and the inner wall surface of the groove portion 300 are coupled to each other, and the elastic force that biases the door plate member 301 toward the second door 208 is provided. And an elastic member 303. The door plate member 301 is in contact with the opening on the upper side of the groove portion 300 in the drawing, and the front end of the door plate member 301 is inclined upward in the storage region X (state shown in FIG. 21A). Further, the swing connecting member 302 is configured to be swingable between a position where the door plate member 301 is inclined upward and a position substantially horizontal to the bottom wall 2a. In addition, in the side wall projection members 270 and 275 provided continuously to the lower end portion of the door storage portion 15, a side wall plate member (not shown) is provided corresponding to the door plate member 301, and corresponds to the door elastic member 303. A side wall elastic member (not shown) is provided.

  When the paper pack 14 is stored in the storage area Y (see FIG. 17) formed by swinging the first door 209 and the second door 210, the bottom surface of the paper pack 14 is the door plate member 301 and the side wall plate member. The door plate member 301 and the side wall plate member are inclined toward the inner side of the storage area Y (the state shown in FIG. 21B). Further, when the paper pack 14 is pushed in the direction of the bottom wall 2a, the door plate member 301 and the side wall plate member swing to a position substantially parallel to the bottom wall 2a and stop (state shown in FIG. 21C). .

  When the paper pack 14 is taken out, the elastic force of the door elastic member 303 returns to the position where the leading ends of the door plate member 301 and the side wall plate member are inclined upward (state shown in FIG. 21A). When the amount of liquid filled in the paper pack 14 is small, the elastic force of the door elastic member 303 may be larger, but even in such a case, the cap member 11 is attached to the paper pack 14. Since the cap member 11 is fixed between the insertion portion 23 and the cap storage portion 12 by being held between the upper end portions, the paper pack 14 can be prevented from being lifted.

  Furthermore, it is necessary to make the door storage portion 15 large by forming a notch portion in each door that can store the door plate member 301 and the side wall plate member inclined upward in a state where each door is stored in the door storage portion 15. It is possible to prevent the side wall 2d from becoming thick. Therefore, it is possible to prevent such adverse effects that the storage portion of the housing 2 becomes narrow and the storage area cannot be used effectively, or the cooler box 1 itself is enlarged.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It can be easily guessed.

  For example, in each of the above embodiments, the cap member 11 is tightly attached to the upper end portions 42a and 42b of the paper pack 14, and the paper pack 14 is stored in the storage areas X and Y. The paper pack 14 may be stored in the storage areas X and Y without being closely attached to the pack 14. In such a case, since each door is fixed, it is possible to prevent the paper pack 14 from being inclined or falling without using the cap member 11. When the cap member 11 is not used, it is possible to store containers of various shapes such as a plastic bottle filled with liquid as well as the paper pack 14. Furthermore, it is needless to say that a cooler box having a configuration not including the cap member 11, the cap storage portion 12, and the insertion portions 23 of the second doors 8 and 10 may be used.

  In the first and third embodiments, the first doors 7 and 207 divided in the vertical direction and the second doors 8 and 208 configured to be extendable and retractable are provided, and the first doors 9 and 209 and the first doors Two sets of two doors 10 and 210 are provided, and in the second embodiment, three sets of the first door 107 divided vertically and the second door 108 configured to be extendable / contracted are provided. The number of combinations of doors is not particularly limited. Furthermore, in the first and second embodiments, the partition member 25 is provided and the depth of the storage area X is adjusted according to the size (height) of the paper pack 14, and in the third embodiment, the door protrusion member 282 is adjusted. And the side wall projection member 285 are provided, and the depth of the storage region X is adjusted according to the size (height) of the paper pack 14, but the combination of the structures is not particularly limited. That is, each door and structure can be combined and set according to the size and application of the cooler box 1.

  Moreover, in each said Example, while connecting the 1st doors 7 and 9 and the side wall 2d with the rod-shaped connection member 20, the 2nd doors 8 and 10 and the 1st doors 7 and 9 are connected with the hinge connection member 22. The first door 9 and the side wall 2d may be connected with a hinge so as to be swingable, or the second door 8, 10 and the first door 7, 9 These connections may be configured to be swingable by connecting with a hinge pin. In other words, any structure may be used as long as each door is configured to be swingable.

  In the above embodiments, the size of the second door 8 can be changed by the protruding member 26 and the through holes 27 and 28. For example, the upper outer frame 8a1 is provided with a through hole. It is good also as a structure which penetrates and fixes the through-hole and the through-hole 27 or the through-hole 28 of the lower side outer frame 8a2 with a pin member. Further, the lower outer frame 8a2 is provided with protrusions pressed outward by elastic force, and through holes are provided at two locations on the upper outer frame 8a1, and the protrusions of the lower outer frame 8a2 are formed in the through holes of the upper outer frame 8a1. It is good also as what is set as the structure fixed by fitting. In this case, the lower outer frame 8a2 can be expanded and contracted by pushing the protrusions of the lower outer frame 8a2 inward and removing the protrusions from the through holes of the upper outer frame 8a1.

  In each of the above embodiments, each door is fixed by the fixing groove 52, the fixing member 55, the fitting portion 285, and the fixing portion including each fitting groove (finger hook portion). It is good also as what comprises the magnetic member from which polarity differs in the bottom wall 2a and the side wall 2d used as the opposing position, and fixes by the attractive force by mutual magnetic force. In addition, as long as each door can be fixed to the position housed in the side wall 2d and the swinging open position, the fixing groove 52, the fixing member 55, the fixing portion, the hinge having a dead point, the magnetic member, and The combination of the structure of the protrusion 59 and the fitting portion 60 described above may be any combination.

  In the first and second embodiments, the first doors 7 and 107 are divided into upper and lower parts, and the second doors 8 and 108 can be expanded and contracted, so that two kinds of paper packs having different sizes (heights) are provided. 14, the first door and the second door are divided into upper and lower parts, respectively, and the upper first door, the upper second door, the lower first door, and the lower second door It is good also as a structure connected, respectively. In such a case, it is assumed that the lower first door and the second door are accommodated in the side wall 2d in a state where the partition member 25 swings so as to be substantially parallel to the bottom wall 2a.

  In the first and second embodiments, the partition member 25 is configured to be swingable by the bar member 31 having both ends supported by the groove formed in the side wall 2d. Grooves for supporting both end portions of the rod 31 are formed with an inner diameter substantially equal to the outer diameter of the rod member 31, and a support portion for supporting the rod member 31 and an inner diameter smaller than the outer diameter of the rod member 31. The moving part to which the member 31 can move may be configured to be continuously formed in a substantially vertical direction with respect to the bottom wall 2 a of the housing 2. In such a case, the bar member 31 can be moved and supported in a substantially vertical direction with respect to the bottom wall 2a of the housing 2, so that the partition member 25 moves in a substantially vertical direction of the bottom wall of the housing and can be arbitrarily set. It can be fixed at the position. Therefore, since the fixing position can be adjusted in accordance with the size (height) of the paper pack 14 to be stored, the distance between the upper end of the paper pack 14 and the opening of the housing 2 can be shortened. It can be easily taken out.

  Moreover, in the said 1st or 2nd Example, although the partition member 25 shall be formed in plate shape, it is set as the structure which provides a mesh-shaped member inside an outer frame, or a rod or pipe is provided inside an outer frame. Etc. in a lattice-like structure provided in the vertical and horizontal directions, or a structure in which rods and pipes are provided only in the vertical direction or only in the horizontal direction inside the outer frame, and the outer shape is smaller than the bottom of the container. It is good also as a thing of only the outer frame which becomes. In such a case, the cooling and heating action for the stored container can be performed efficiently.

  Moreover, in the said 1st or 2nd Example, the height of the 1st doors 7 and 9 and the 2nd doors 8 and 10 (container) and the depth of the storage part of the housing | casing 2 were formed substantially equal. Although it was set as the cooler box 1, it is good also as a cooler box whose depth of the housing | casing 2 is longer than the height of each door. In such a cooler box, even when the upper end portion of each door is disposed at a position that is substantially the same as the opening of the housing 2, the partition member 25 causes the housing areas X and Y to be connected to the opening side of the housing 2. Since the bottom wall 2a side can be partitioned, other items, containers, etc. can be stored in the area below each door. In this case, it is preferable that the partition member 25 is configured to be movable in a substantially vertical direction of the bottom wall 2a. Furthermore, since the upper end of the paper pack 14 can be clamped by the cap member 11 and fixed between the insertion portion 23 and the cap storage portion 12, the partition member 25 may not be provided. That is, the bottom of the paper pack 14 may not be supported but may be stored in a suspended state.

  Moreover, in the said 3rd Example, while forming the length in the thickness direction of a 1st door in a thickness direction of a 1st door in a said 1st door, the thickness of the 2nd door of a 2nd notch part is substantially equivalent. The length in the direction is formed to be substantially the same as that of the second door, and the door protrusion member and the side wall protrusion member are substantially the maximum size substantially equivalent to the first notch portion and the second notch portion. However, as long as the bottom surface of the paper pack 14 can be supported by the door projection member and the side wall projection member, the length of the door projection member and the side wall projection member may be shortened. Depending on the thickness, the first notch and the second notch may be formed with a small size. In addition, when forming the length of a door projection member and a side wall projection member short, the length which becomes at least half with respect to the thickness of each door is preferable. This is because when the length of the door projection member and the side wall projection member is less than half of the thickness of each door, the paper pack 14 falls in the direction of the bottom wall 2a without being able to support the bottom surface of the paper pack 14. This is because there is a possibility that it will end up.
