Description

  The present invention relates to a carton (top open carton) of a type in which a part of the top surface is opened and closed and the contents are taken out from the opened top surface.

  Each of the cartons described in Patent Documents 1 and 2 has an opening formed in advance in a rectangular top surface portion, and the top surface opening is formed on the left and right side surfaces where the short side of the rectangular top surface portion is located on the side. It has a structure in which both the left and right sides are closed by a cover plate that is continuous with the upper end of the section. The top surface opening is closed by moving the two cover plates outward in opposite directions. In both Patent Documents 1 and 2, since the moving direction of the cover plate is the longitudinal direction of the carton, the moving distance of the cover plate for opening the top surface (unlocking) is long. Moreover, the entire top surface opening cannot be opened unless both the left and right cover plates are moved.

  It is an object of the present invention to provide a top open carton in which the top surface opening can be easily opened and closed.

  The top open carton according to the present invention has a rectangular outer top surface portion in which a container outlet is opened, a rectangular bottom surface portion opposed to the outer top surface portion, and a long side and a short side of the top surface portion and the bottom surface portion. Two long sides facing each other and two short sides facing each other are provided, one of the two long sides facing the boundary with the bottom or the long side. The inner slide top surface is continuous with the leading edge of the side surface of the pivotable long side, and the inner slide top surface is in the closed state. Is placed along the inner surface of the outer top surface portion to close the contents outlet of the outer top surface portion from the inner side, and in the open state, the pivotable long side is turned outward. In conjunction with the rotation of the side of the long side, Serial long sides is slid outward of the inner slide top surface section which is continuous to the I side surface portion, characterized in that solving the closure of the takeout said contained object.

  Since the inner slide top surface is continuous with the leading edge (upper edge) of the pivotable long side surface, when the pivotable long side pivots outward, the inner slide top The surface portion slides outward in conjunction with this. According to the present invention, since the inner slide top surface portion is continuous on the side surface portion with the long side, the slide movement direction of the inner slide top surface portion is the short direction of the carton. The accommodation outlet opened in the outer top surface portion can be opened and closed by a short distance movement of the inner slide top surface portion. Further, since only one of the two long sides has to be rotated, the top surface opening can be easily opened and closed.

  In a preferred embodiment, each of the pivotable long sides is housed in the carton in the closed state at each of both ends of the side wall and exposed to the outside of the carton in the open state. A side rotation surface portion that closes a side opening formed by the portion and the inner slide top surface portion is continuous. When the side of the long side is rotated outward and the top surface of the inner slide is moved outward, the contents are received from the side opening formed by the side of the long side and the top surface of the inner slide. Prevents spilling out.

  In one embodiment, the outer top surface portion, the non-rotating long side surface portion, the bottom surface portion, the rotatable long side surface portion, and the inner slide top surface portion are arranged in a row in this order, The leading end is continuous with the leading edge of the outer top surface, and a part of the leading end is bonded to the outer surface of the side surface of the pivotable long side. A cut portion is formed in front of the bonded portion, and by cutting the cut portion, one of the two long side side portions can be rotated about the boundary with the bottom portion, In addition, the inner slide side surface portion is slidable. Only when the cut portion (for example, the zipper portion) is cut, the side surface portion of the long side can be rotated, and the inner slide top surface portion can be slid. By looking at the cut-out part, you can know whether it has been opened or not.

  In another embodiment, the outer top surface portion, the non-rotating long side surface portion, the bottom surface portion, the rotatable long side surface portion, and the inner slide top surface portion are arranged in a row in this order. The range defined by the cut line formed near the front edge of the outer top surface part is bonded to the outer surface of the inner slide top surface part and is affixed to the body, and the range defined by the cut line is the outer top surface part. By separating from the side, one of the two long side side surfaces can be pivoted about the boundary with the bottom surface, and the inner slide side surface can be slid. Also in this mode, it is possible to know whether it has been opened once or not by seeing the cut line.

  In one embodiment, an adhesive portion connected to the leading edge of the inner slide top surface portion via a tear line is bonded to the inner surface of the outer top surface portion. In the unopened state, the inner slide top surface portion can be made difficult to fall into the carton (not easily bent).

  Preferably, a reinforcing flap along the inner surface of the side surface portion of the inner side surface of the inner slide top surface portion is continuous with the inner surface of the side surface portion of the wrinkle side opposite to the side surface portion. Since the reinforced flap plays the role of a beam, the inner slide top surface is less likely to fall into the carton (not easily deflected).

  In one embodiment, an adhesive portion is provided via a tear line (for example, perforation) continuously to the reinforcing flap that is continuous with the leading edge of the inner slide top surface portion, and the adhesive portion is bonded to the inner surface of the carton. Has been. When not opened, the inner slide top surface portion can be made difficult to fall into the carton (not easily bent).

  Preferably, a stopper mechanism for stopping the outward sliding movement of the inner slide top surface part is provided. Various structures are conceivable for the stopper mechanism.

  The first stopper mechanism is configured by adjusting the dimension of the side rotation surface portion so that the edge portion of at least one of the side rotation surface portions contacts the carton during the rotation. The rotation of the side rotation surface portion is stopped by the frictional force between the edge of the side rotation surface portion and the carton, whereby the rotation of the long side surface portion connected to the side rotation surface portion, and the above The sliding movement of the inner slide top surface portion that connects to the long side surface portion stops.

  The second stopper mechanism is formed on at least one of the boundary between the protrusion formed on at least one tip of the side rotation surface portion, the outer top surface portion, and the two short side surfaces, It is comprised from the slit which the said protrusion engages in the middle of rotation of a side rotation surface part.

  The third stopper mechanism is formed with a locking piece provided on at least one side of the inner slide top surface portion and at least one upper edge of the side surface portion with the two short sides, It is comprised from the step part which the said locking piece contacts in the middle of a slide movement.

  The fourth stopper mechanism is formed with a locking piece provided on at least one side of the inner slide top surface portion and at least one upper edge of the side surface portion with the two short sides, It is composed of an outwardly protruding locked protrusion with which the locking piece abuts during the sliding movement.

  In any of the first stopper mechanism to the fourth stopper mechanism, the sliding movement of the inner slide top surface portion can be stopped halfway, so that the inner slide top surface portion completely jumps out of the carton. Is prevented.

  The present invention also provides a top open carton having a square outer top surface and bottom surface. This top open carton is composed of a square outer top surface with a container outlet, a square bottom surface facing the outer top surface, a front surface and a back surface connecting the four sides of the outer top surface and the bottom surface, respectively. Part and two side parts, the front part being pivotable about a boundary with the bottom part or a crease provided on the front part, and at the front edge of the pivotable front part The inner slide top surface portion is continuous, and in the closed state, the inner slide top surface portion is aligned with the inner surface of the outer top surface portion to close the container outlet of the outer top surface portion from the inside and in the open state. By rotating the rotatable front portion outward, the inner slide top surface portion continuous to the front portion is slid outwardly in conjunction with the rotation of the front portion, and the contents are removed. Solve exit closure It is characterized in. The top surface opening can be easily opened and closed by sliding and moving the inner slide top surface continuous to the front by rotation of only the front.

(First embodiment)
1 to 9 show a top open carton 1 according to a first embodiment. The top open carton 1 of the first embodiment is made of a single cardboard. Instead of cardboard, cardboard, plastic sheet, or a composite material thereof may be used. FIG. 1 is a development view of a cardboard (blank) forming the carton 1, and is a view of a surface that becomes the inner side of the carton 1. An alternate long and short dash line indicates a fold line that is valley-folded when the carton 1 is formed. In order to facilitate the folding, a fold line processing or a crease is applied along the one-dot chain line. Hatching indicates a portion (glue portion N) where an adhesive or the like is provided. 2 to 5 show the assembly process of the carton 1. FIG. 6 shows the carton 1 that has been assembled. 7 and 8 show the opening (opening) process of the carton 1. FIG. 9 shows the left side surface of the carton 1 in the state shown in FIG.

  First, referring to FIG. 1, the carton 1 has a rectangular bottom surface portion 11. A rectangular front portion 12 and a rear portion 13 are continuously extended in opposite directions from the two long sides on the left and right sides of the bottom portion 11. Further, the inner side surface portions 21L and 21R continuously extend in opposite directions from the two upper and lower short sides of the rectangular bottom surface portion 11, respectively. Both side portions of the inner side surface portions 21L and 21R have a design that is smoothly recessed inward. The widths of the front portion 12, the rear portion 13, and the left and right inner side portions 21L, 21R are substantially equal, and these widths define the height of the carton 1 when assembled. Further, an inner slide top surface portion 14 and an outer top surface portion 15 continuously extend in opposite directions on the right edge of the front portion 12 and the left edge of the back surface portion 13, respectively. The inner slide top surface portion 14 has a design in which a tip edge thereof is slightly recessed inward. A container outlet (product take-out window) 15A having an oval shape (a shape in which two semicircles are connected by a straight line) is opened along the longitudinal direction of the rectangular outer top face 15 at substantially the center of the outer top face 15. ing. Further, a distal end portion 16 including a zipper portion 16A, an adhesive portion (glue margin portion) 16B, and a knob portion 16C is continuous with the distal end edge of the outer top surface portion 15. A glue portion N for bonding is provided on the bonding portion 16B.

  Further, insertion portions 22L and 22R are continuously extended in opposite directions at the leading edges of the inner side surfaces 21L and 21R which are continuous with the two short sides of the bottom surface portion 11, respectively. Furthermore, generally fan-shaped flaps 23L and 23R are continuously extended in opposite directions on the two short sides of the front portion 12, respectively. Nearly two rectangular flaps 24L and 24R extend in opposite directions on the two short sides of the back surface portion 13, respectively. The length of the fan-shaped flaps 23L and 23R that are respectively continuous with the two short sides of the front portion 12 (the distance from the boundary with the front portion 12 to the tip of the fan-shaped flaps 23L and 23R) It is slightly longer than the width of 21L and 21R (corresponding to the height of carton 1 when assembled). On the two short sides of the outer top surface portion 15, outer side surface portions 25L and 25R continuously extend in opposite directions. The outer side surface portions 25L and 25R are also provided with glue portions N for adhesion.

  Referring to FIG. 2, first, front part 12 is folded at the boundary with bottom part 11. Referring to FIG. 3, the outer top surface portion 15 is then folded at the boundary with the back surface portion 13. As a result, the outer top surface portion 15 is superimposed on the inner slide top surface portion 14. Further, the adhesive portion 16B of the tip portion 16 that is folded together with the outer top surface portion 15 is adhered to the front surface portion 12 by the paste portion N and is affixed to the body.

  Referring to FIG. 4, the front portion 12 and the back portion 13 are raised up at a substantially right angle with respect to the bottom portion 11. A sleeve that is open on both sides is shaped.

  Referring to FIG. 5, one side opening, for example, the left side opening is closed first. A flap 24L continuous with the back surface portion 13 is folded inward at a substantially right angle with respect to the back surface portion 13, and then a fan-shaped flap 23L continuous with the front surface portion 12 is folded inward at a substantially right angle with respect to the front surface portion 12. . Further, the inner side wall portion 21L continuous to the bottom surface portion 11 is folded inward substantially at a right angle to the bottom surface portion 11, and the insertion portion 22L at the tip of the inner side wall surface portion 21L is further folded inward at a right angle. Then, the inner surface of the inner slide top surface portion 14 is inserted into the hook (the lower face is the hook). The insertion portion 22L into which the inner surface of the inner slide top surface portion 14 is inserted into the alligator serves as a support for preventing the inner slide top surface portion 14 from falling. Finally, the outer side surface portion 25L continuous with the outer top surface portion 15 is folded inward at a right angle to the outer top surface portion 15, and is adhered to the outer surface of the inner side surface portion 21L by the glue portion N.

  From the other side opening that is not closed, in the above case, the right side opening, a stored item (such as confectionery) (not shown) is stored in the carton 1 (end load). Thereafter, the right side opening is closed in the same manner as the left side. The carton 1 in which the stored items are stored is completed (FIG. 6). The carton 1 of the first embodiment (and the cartons of other embodiments described later) can be automatically manufactured by an end road cartoner.

  The unpacking (opening) process of the carton 1 will be described with reference to FIGS.

  First, referring to FIG. 7, the zipper part 16A superimposed on the front part 12 of the carton 1 is moved sideways and peeled off. As a result, the connection between the front surface portion 12 and the outer top surface portion 15 is lost.

  Next, the picking part 16C is picked with a finger and pulled outward (slightly downward direction). 8 and 9, when the knob portion 16C is pulled outward, the adhesive portion 16B connected to the knob portion 16C and the front surface portion 12 bonded to the adhesive portion 16B are pivoted on the boundary with the bottom surface portion 11. To turn. As described above, since the inner slide top surface portion 14 is continuous with the front portion 12, the inner slide top surface portion 14 slides out of the carton 1 in conjunction with the rotation of the front portion 12. , Gradually exposed outside. The closure of the container outlet 15A by the inner slide top surface portion 14 is released, and the container outlet 15A is opened.

  Since the fan-shaped flaps 23L and 23R are continuous on both sides of the front portion 12, the fan-shaped flaps 23L and 23R are also rotated together with the front portion 12 and gradually exposed to the outside of the carton 1. Since the side opening formed by the front surface portion 12 and the inner slide top surface portion 14 is closed by the fan-shaped flaps 23L and 23R, the contents do not come out of the carton 1 therefrom.

  As described above, the length of the fan-shaped flaps 23L and 23R is slightly longer than the height of the inner side face portions 21L and 21R, that is, the height of the carton 1. For this reason, if the front portion 12 continues to rotate, the edge portions of the fan-shaped flaps 23L and 23R come into contact with (rub against) the carton 1 (insertion portions 22L and 22R), so that braking is applied on the way (front portion). (It becomes heavy to turn 12) (see FIG. 9). This prevents the inner slide top surface portion 14 from being completely taken out of the carton 1. Hereinafter, the stopper mechanism for the sliding movement of the inner slide top surface portion 14 using the edge portions of the fan-shaped flaps 23L and 23R shown in the first embodiment is referred to as a first stopper mechanism.

(Second embodiment)

  Referring to the developed view of FIG. 10, the top open carton 2 of the second embodiment is provided with an adhesive portion 14A that is continuous via a perforation M at the tip edge (right end in FIG. 10) of the inner slide top surface portion 14. A slit S is formed at each of the boundaries between the outer top surface portion 15 and the left and right outer side surface portions 25L and 25R that are continuous to both ends (upper and lower ends in FIG. 10), a fan-shaped flap 23L, The shape of 23R is different from the top open carton 1 (see FIG. 1) of the first embodiment in that the shape of 23R is different, including the point that a protrusion 31 facing outward is formed at the tip.

  Referring to FIG. 11, the top open carton 2 of the second embodiment is also assembled in the same manner as the top open carton 1 of the first embodiment. The adhesive portion 14A continuous to the tip of the inner slide top surface portion 14 is bonded to the inner surface of the frame portion of the outer top surface portion 15 by the glue portion N. Since the inner slide top surface portion 14 is easily fixed along the inner surface of the outer top surface portion 15 by the adhesive portion 14A, it is possible to prevent the inner slide top surface portion 14 from falling into the carton 2 in the assembled state. Can be reduced.

  When opening the carton 2 (opening the container outlet 15A), the front portion 12 is rotated by pulling the knob 16C outward after the zipper portion 16A is peeled off in the same manner as in the first embodiment. The inner slide top surface portion 14 connected to the front surface portion 12 slides outward. Here, since the adhesive portion 14A at the tip of the inner slide top surface portion 14 is only connected to the inner slide top surface portion 14 by the perforation M, when the inner slide top surface portion 14 is slid, the perforation M is cut and the slide The inner top surface portion 14 and the adhesive portion 14A at the tip thereof are separated. The cut adhesive part 14 </ b> A remains adhered to the inner surface of the frame part of the outer top surface part 15.

  As described above, the protrusion 31 is formed at the tip of the left and right fan-shaped flaps 23L and 23R, and the slit S is formed at the boundary between the outer top surface portion 15 and the left and right outer side surface portions 25L and 25R. ing. Referring to FIG. 12, when the fan-shaped flaps 23L and 23R rotate together with the front face 12, the protrusions 31 at the tips of the fan-shaped flaps 23L and 23R enter the slit S along the way. The rotation of the fan-shaped flaps 23L and 23R and the sliding movement of the inner slide top surface portion 14 are stopped. It is possible to prevent the inner slide top surface portion 14 from completely coming out of the carton 2. Hereinafter, the stopper mechanism for sliding the inner slide top surface portion 14 using the protrusion 31 and the slit S at the tips of the sector flaps 23L and 23R shown in the second embodiment will be referred to as a second stopper mechanism.

(Third embodiment)
FIGS. 13 to 16 show the top open carton 3 of the third embodiment. FIG. 13 shows a developed view and FIG. 14 shows an assembled state. FIG. 15 shows the left side surface of the assembled carton 3 with the outer side surface portion 25L omitted. FIG. 16 shows the left side surface of the opened carton 3 with the outer side surface portion 25L omitted.

Different from carton 1 (FIG. 1).

  The method for assembling the top open carton 3 of the third embodiment is the same as the method for assembling the top open carton 1 of the first embodiment (see FIGS. 2 to 5). The locking pieces 42 extending laterally from both side edges of the inner slide top surface portion 14 are bent inward substantially at a right angle simultaneously when the left and right outer side surface portions 25L and 25R are bent. Referring to FIG. 14, in the assembled state, the locking piece 42 is located between the outer side surface portion 25L (25R) and the inner side surface portion 21L (21R). The locking piece 42 also serves to prevent the inner slide top surface portion 14 from falling.

  Referring to FIG. 15, in the assembled state (the closed state of the container outlet 15 </ b> A), the locking piece 42 is located on the back of the carton 3. When the front surface portion 12 is rotated with reference to FIG. 16 and the inner slide top surface portion 14 is slid, the locking piece 42 is also slid forward. In the middle of the slide movement, the locking piece 42 hits the step 41 formed on the left and right inner side surfaces 21L, 21R, and the slide movement of the inner slide top surface part 14 stops here. It is possible to prevent the inner slide top surface portion 14 from being completely taken out of the carton 3. Hereinafter, the stopper mechanism for the sliding movement of the inner slide top surface portion 14 using the locking piece 42 and the step portions 41 formed on the inner side surface portions 21L and 21R shown in the third embodiment will be referred to as a third stopper mechanism. Call it.

(Fourth embodiment)
17 to 19 show the top open carton 4 of the fourth embodiment, and FIG. 17 shows a development view. FIG. 18 shows the left side surface of the carton 4 in the assembled state with the left outer side surface portion 25L omitted. FIG. 19 shows the left side surface of the opened carton 4 with the left outer side surface portion 25L omitted. The top open carton 3 of the third embodiment shown in FIGS. 13 to 16 is that the left and right inner side wall portions 21L, 21R are not formed with stepped portions 41, and the left and right inner side wall portions 21L, A difference is that a cut K having a convex shape toward the left and right inner side surface portions 21L and 21R is formed at the boundary between 21R and the insertion portions 22L and 22R continuous thereto.

  When the insertion portions 22L and 22R are bent at right angles to the left and right inner side surface portions 21L and 21R, the above-mentioned cut K causes the small engagement to rise in the direction opposite to the direction in which the insertion portions 22L and 22R are bent. A locking projection 44 is formed (in FIGS. 18 and 19, the locked projection 44 slightly protrudes from the front of the drawing). The above-described locking pieces 42 collide with the locked projections 44, thereby preventing the sliding movement of the inner slide top surface portion 14 from stopping and preventing the inner slide top surface portion 14 from being completely exposed outside the carton 4. Is done. Hereinafter, the stopper function of the sliding movement of the inner slide top surface portion 14 using the locking piece 42 and the locked protrusion 44 shown in the fourth embodiment is referred to as a fourth stopper mechanism.

In addition, the adhesive flap 17A is further continuously formed on the front edge of the reinforcing flap 17 through the perforation M, and the container outlet 15B opened in the outer top surface portion 15 is connected to the back surface portion 13. It is different from the top open carton 4 (see FIG. 17) of the fourth embodiment in that it is formed widely reaching the boundary. The stopper mechanism of the inner slide top surface portion 14 is a fourth stopper mechanism.

  Referring to FIG. 21, the reinforcing flap 17 continuing to the leading edge of the inner slide top surface portion 14 is bent inward substantially at right angles to the inner slide top surface portion 14, and is assembled to the inner surface of the back surface portion 13 in the assembled state. Along. An adhesive portion 17A that is continuous with the leading edge of the reinforcing flap 17 is adhered to the inner surface of the back surface portion 13 by the glue portion N. By providing the reinforced flap 17, the inner slide top surface portion 14 is less likely to fall into the carton 5 (is less likely to bend). In addition, since the bonding portion 17A is bonded to the back surface portion 13 instead of the outer top surface portion 15, a frame portion (a range in which no container outlet is formed) is secured between the outer top surface portion 15 and the back surface portion 13. There is no need (for example, compare with the carton 3 (FIG. 14) of the third embodiment). As a result, it is possible to widen the container outlet 15B up to the boundary position between the outer top surface portion 15 and the back surface portion 13.

  Referring to FIG. 22, when the inner slide top surface portion 14 is slid, the perforation M at the boundary between the reinforcing flap 17 and the adhesive portion 17A is cut, and the reinforcing flap 17 and the adhesive portion 17A are separated. The cut adhesive part 17A remains attached to the inner surface of the back face part 13. The reinforcing flap 17 moves together with the inner slide top surface portion 14. In addition, since the notch 17a is formed in the base part (boundary with the inner side slide top surface part 14) of the both ends of the reinforcement | strengthening flap 17, the inner surface of the inner side slide top surface part 14 of the reinforcement | strengthening flap 17 is in the middle of the movement. There is no interference with the plugs 22L and 22R inserted into the alligator.
