DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[Example 1]
As an example of the upper lid carton according to claims 1 and 2 of the present invention, FIG. 1 (a) is a sketch in the upper lid opening self-standing state, and FIG. 1 (b) is a side sectional view of the opening / closing operation of the upper lid portion seen from the side. FIG. 1 (c) shows an enlarged view of the hinge portion of the horizontal folding line portion that becomes the upper lid rotation support shaft, and FIG. 2 shows a development view of the upper lid carton developed on one blank.
[0008]
As shown in FIG. 2, the upper lid carton according to claims 1 and 2 of the present invention includes a rear plate (10), a top plate (20), a front plate (30), and a bottom plate (40) constituting the body of the rectangular parallelepiped. , Rear outer plate (50), side plates (24R, 24L), (44R, 44L) constituting left and right side portions thereof, upper lid top plate (60) constituting upper lid portion, upper lid front plate (70), upper lid It has a side plate (64R, 64L) and some adhesive pieces for bonding the members to each other at the time of assembly, and is prepared by a punching machine from a pattern paper with outlines and cut lines shown as solid lines. . Further, at the time of this punching, an opening for taking out the contents while leaving the peripheral edge is simultaneously punched and formed in the central portion straddling the top plate (20) and the front plate (30).
[0009]
The assembly of the top lid carton is performed in the following procedure. That is, the body part of the carton is connected to the rear plate (10), the top plate (20), the front plate (30), and the bottom plate (40) by the horizontal folding lines indicated by the one-dot chain line in FIG. After a rectangular parallelepiped is formed by folding at right angles, the inner side of the rear outer plate (50) and the outer surface of the rear plate (10) are connected to each other so as to be overlapped in a band and sacked, and the left and right are not closed. It is formed.
[0010]
In addition, a substantially rectangular opening is provided in the center of the top plate (20) and the front plate (30), the contents can be taken out, and the next sheet-like content is unnecessarily erroneous. The left and right edges are left as appropriate so that they do not come out. In this embodiment, the opening has a substantially rectangular shape, but there is no problem even with a polygonal, oval or elliptical opening. Further, in the middle of the upper edge of the opening of the front plate (30), the upper lid locking piece (32) is provided with an upper notch locking piece auxiliary cut (33) for easily locking the upper lid when closed. It can be freely bent at a horizontal fold line (33a) having
[0011]
Next, one of the left and right side portions, for example, the right side portion is adhesively glued on the front plate adhesive piece (34R) and the rear plate adhesive piece (54R), and each side plate is bent at a right angle along the vertical folding line, and then the side plate (44R). Then, the adhesive is further glued on the side plate (44R) to adhere to the side plate (24R). With this one side closed, a predetermined amount of sheet-like contents folded in advance are filled from the side, and then the other side is folded and bonded in the same manner to assemble the carton box body. Is completed.
[0012]
Next, when assembling the upper lid portion (100), the upper lid top plate (60) is parallel to the horizontal folding line (51a) which is the boundary between the rear outer plate (50) and the upper lid top plate (60). A crease is made in advance using a muscle pusher or the like so that the hinge side folding line (53h) provided by shifting toward the side does not mistakenly be on the same straight line. By providing the horizontal fold line (53h) of the hinge part with a slight shift from the horizontal fold line (51a) serving as the rotation support shaft of the upper lid part, when the upper lid part is opened and closed, the upper lid part is opened. It becomes a pawl against the movement of the part to return, and the locking effect of the hinge part is produced.
[0013]
After performing the above-described crease operation, the top lid top plate (60) is folded from the rear outer plate (50) with the horizontal folding line (51a) as a main body, and then the upper lid front plate (70) is also bent at a right angle, and the top lid of the tip The front plate reinforcing plate (76) is adhesively glued on the inside, folded back and bonded to the upper lid front plate (70). Also, the adhesive lid glued upper lid front adhesive pieces (74R, 74L) are bent at right angles and then adhered to the inner side of the upper lid side plates (64R, 64L) to form the upper lid portion (100) having the front and left and right sides. Is done. In this state, since it is not a sealed state required at the time of distribution, among the upper lid side plates (64R, 64L), a substantially triangular side plate reinforcing plate (separated by an upper lid side plate separation perforation (63)) ( 66R, 66L), and the upper lid portion (100) is covered and adhered to the box body, and the upper lid front plate reinforcing plate (76) formed by bending is also glued in a spot shape. And temporarily attach it so that the upper lid does not open.
In this state, or in a state where the entire surface is packaged with a shrink-like resin film, it is distributed to consumers.
[0014]
At the start of use, the consumer first holds the front surface portion of the upper lid of the carton that is temporarily fixed and pulls it upward, so that the upper lid side plate (64R, 64L) that forms the upper lid portion (100) is the upper lid side plate. The side plate reinforcing plates (66R, 66L) bonded to the carton body side surface portion are separated with the separation perforation (63) as a boundary, and are opened upward as the upper lid portion to expose the opening.
[0015]
In the upper lid carton of Example 1, the upper lid portion (100) is a three-dimensional upper lid portion comprising an upper lid front plate (70), left and right upper lid side plates (64R, 64L), and an upper lid top plate (60). At the place where it is connected to the outer plate (50), which is the rotation support shaft of the upper lid, there is a horizontal folding line (51a) and two hinges (53) on the same axis. As shown in FIG. 1 (c), the hinge part (53) is substantially composed of a hinge part vertical cut (53v) and a hinge part horizontal fold line (53h) provided so as to be offset from the horizontal fold line by several mm toward the top lid top plate. Since it is an H-shaped hinge, the lower part of the hinge part is stretched against the opening / closing operation of the upper cover part that moves with the horizontal folding line (51a) as the rotation support shaft, and the effect of trying to stop it becomes an obstacle. In a state where the portion is further opened from about 120 degrees to 140 degrees from a right angle, the upper lid portion (100) is caused by the weight balance of the three-dimensional upper lid portion and the latching movement of the hinge portion on the fold line. Even if the hand is released, it remains open and there is no need to hold the upper lid by hand when taking out the contents.
[0016]
The hinge shape in this embodiment has been described as being substantially H-shaped consisting of three straight lines. However, the longitudinal cut may be an arc-shaped cut or a <cut-shaped cut, and a horizontal direction connecting these cuts. The fold line may also be an arc shape or a V-shaped fold line, and the combination may be any hinge shape that produces the above-mentioned tension effect, and three or more hinge portions are provided on the horizontal fold line (51a) that is the rotating shaft. It doesn't matter.
[0017]
Therefore, it is possible to draw out contents such as folded sheet sheets and bags, such as kitchen paper, tissue paper, and vinyl bags, which are viewed from the opening, with one hand and use them. In addition, if the contents are folded and stored in a Z-shape, when one sheet is taken out, a part of the sheet of the next leaf that is folded is located in the opening in a semi-standing state. It is also convenient to use.
[0018]
Further, when the upper lid portion is closed after use, the upper lid top plate (60) of the upper lid portion (100) is attached to the top plate (20) as shown in FIG. ) And the upper lid front plate (70) is in a closed state overlying the front plate (30).
[0019]
However, since the upper lid portion is not locked in this state, in order to lock the upper lid portion locking piece (32) connected to the opening end of the front plate (30), the upper lid portion locking piece auxiliary cut ( 33) is bent slightly outward in accordance with the horizontal folding line (33a) having the upper lid front plate reinforcing plate (76) provided on the inner side of the front end portion of the upper lid front plate (70) in the upper lid portion (100). Hook and lock. When the upper cover part (100) is opened again, if the upper cover part (32) is pulled up as it is with a certain level of force, the upper cover part locking piece (32) is warped back, the lock is released, and it has a simple structure and has recloseability. A lock mechanism can be realized.
[0020]
[ Reference Example 1 ]
Also as a reference example of the upper lid cartons according to the present onset bright, the sketch in the upper lid opened self-supporting in FIG. 3 (a), a side cross-sectional view in FIG. 3 (b), the transverse fold line portion comprising an upper lid section rotating shaft An enlarged view of the inverted U-shaped cut protrusion is shown in FIG. 3C, and a developed view of the upper cover carton developed on one blank is shown in FIG.
[0021]
As shown in FIG. 4, the upper cover carton of this reference example has a rear plate (10), a top plate (20), a front plate (30), a bottom plate (40), a rear outer plate (50 ) And the side plates (24R, 24L) constituting the left and right side portions thereof, and the members of the long upper lid top plate (62b), the short upper lid top plate (62a) and the upper lid front plate (70) constituting the upper lid portion during assembly. It has several adhesive pieces for bonding the members to each other, and is prepared by a punching machine from the pattern paper with outlines and cut lines shown as solid lines. Further, at the time of this punching, an opening for taking out the contents while leaving the peripheral edge is simultaneously punched and formed in the central portion straddling the top plate (20) and the front plate (30).
[0022]
In this reference example, the upper lid top plate (60) is composed of a long upper lid top plate (62b) and a short upper lid top plate (62a) separated by an upper lid top plate perforation (61). In the center part on the horizontal folding line (51a) serving as the rotation support shaft, the notch of the inverted U-shaped incision protrusion (55) having auxiliary protrusions (55a) on both the left and right sides as shown in FIG. It is formed during the process. The U-shaped cut protrusion corresponding to the reverse U-shaped cut projection and the lower portion formed at the lower end of the upper lid by carton assembly described later are caught by the paper thickness of the carton in the opening / closing operation of the upper lid (100) described later. The open upper lid part (100) has a locking effect on the movement to return.
[0023]
The assembling of the carton body is substantially the same as that of the first embodiment described above. First, the carton body member is folded according to the horizontal folding line, and the rear outer plate (50) and the rear plate (10) are located at the upper side. Glued to match. At this time, the lower U-shaped cut protrusion (55) provided at the central portion of the horizontal fold line (51a) is not creased and the lower portion is bonded to the fold line equivalent portion. Also, the front plate reinforcing plate (72R, 72L) portion of the upper cover front plate (70) separated by the perforation (73) of the upper cover front plate is bonded and glued on the front plate (30). After the parts are sealed and a cylindrical rectangular parallelepiped that is not closed on both sides is formed and filled with the contents, the left and right side plates are bonded to complete the assembly of the carton.
[0024]
In the same manner as in the first embodiment, the insertion plate (72M) on the front part of the carton is first pulled up, and the upper lid front plate (70) that has been adhesively sealed is separated from the upper lid front plate. The top is cut off from the eyes (73) and the upper lid (100) is opened. Next, the upper lid top plate perforation (61) provided in the upper lid top plate (60) is lightly bent in a reverse shape. When opening the upper cover part (100), the upper cover part (100) is rotated backward by opening over the inverted U-shaped incision protrusion (55) provided at the center of the horizontal folding line (51a) serving as a rotation support shaft. In a state where the upper lid portion (100) is greatly opened to the rear, the weight balance of the upper lid portion (100) which is three-dimensional when viewed from the side as shown in FIG. Due to the locking effect of the inverted U-shaped incision protrusion (55) against the returning movement, the upper lid part (100) is self-supporting in an almost upright state, so the consumer presses the contents so as not to return the upper lid part. You can easily take it out with one hand without taking it out.
[0025]
Moreover, when closing the upper lid part (100), it is possible to return to the closed state before use so as to cover the opening as long as the upper lid part (100) is closed with an appropriate force sufficient to get over the inverted U-shaped cutting protrusion. In order to lock the upper lid, the insertion piece gripping plate (72M) provided to be connected to the tip of the upper lid front plate (70) is slightly warped upward according to the fold line and is inserted at the center of the fold line. The piece (71) can be inserted and locked in the insertion piece locking portion (31) in the front plate (30), and the contents can be protected from the assumed environment of use such as a kitchen such as splashing water or splashing oil. it can. In the present embodiment, one reverse U-shaped cut protrusion (55) is provided on the horizontal folding line (51a). However, the reverse U-shaped cut protrusion (55a) has a plurality of reverse U-shaped cut protrusions having appropriate lengths. However, the shape is the same, and the shape may be an appropriate shape as long as the locking effect is similarly obtained as a tongue piece such as an ellipse or an ellipse in consideration of the design other than the inverted U-shape.
[0026]
【The invention's effect】
As described above, in the upper lid carton according to the first and second aspects of the present invention, a set of two longitudinal cuts in the horizontal folding line portion serving as the rotation support shaft of the upper lid portion and the interval between them are shifted closer to the upper lid than the horizontal folding line. The upper lid has a three-dimensional shape because it has a substantially H-shaped hinge formed by a lateral folding line provided and has the effect of obstructing and locking the opening / closing operation of the upper lid. It is possible to maintain a state in which the upper lid is opened in combination with being easy to take a weight balance at an angle in the opened state, and the upper lid portion is used to hold the sheet-like contents stored by folding from the opening. Can be easily taken out without being suppressed with one hand. In addition, the upper lid can be closed by a light pulling action from the state where the upper lid is open and self-supporting. In the closed state, the upper lid is locked by the upper lid locking portion, and the opening is completely closed by the upper lid. It is possible to protect the contents from splashing water or splashing oil in the kitchen, etc., and when necessary, the user can insert the gripping piece with one hand and open it easily. The carton can be provided with simple configuration and assembly. Furthermore, the upper lid has a three-dimensional shape with a side surface portion on the upper lid and a front surface portion on the upper lid, so that the upper lid can be opened and closed more smoothly as intended, and a high-class feeling can be produced and differentiated from other similar products. And the rigidity of the box is increased.
[0027]
Further, in the upper lid carton of the reference example of the present invention, the horizontal folding line portion serving as the rotation support shaft of the upper lid portion has a tongue-like cut projection portion such as an inverted U shape, and the tongue-like cut projection portion is the upper lid portion. The top cover is coupled with the fact that the top plate is shaped like an upside down shape when the top cover is open, and the three-dimensional shape makes it easy to take a weight balance at a certain angle. Since it is possible to maintain the open state in a state where the portion is almost upright, the sheet-like contents stored by being folded from the opening can be easily taken out without holding the upper lid portion with one hand. Further, the closing operation from the self-supporting state in which the upper lid portion is opened can be performed with a light force, and the effect of being able to be locked is the same as in the carton of the first and second aspects.
