In the explanation of the present invention, the wrap carton shown in the drawings relates to a carton for storing a synthetic resin film wound around a paper tube in a roll shape, and the film is the leading part whenever necessary in general homes, stores and the like. The so-called food wrapping film, which is drawn out under the required length and is mainly used for packaging foods such as seafood, side dishes and fruits, is illustrated. Therefore, the present invention is not limited to the film, and can be used for aluminum foil, wax paper, and other roll-shaped packaging materials at home or stores.
[0008]
As shown in FIG. 1, the carton blank of the wrap carton of the present invention is made of rectangular cardboard, and is composed of a container body R, a lid L, and a cutting part 20 after assembling. The body L can be opened and closed, and the lid body L that overlaps the opening surface of the container main body R is connected to the upper edge of the rear surface of the container main body R through a crease so that it can be reclosed (reclosed). doing.
Specifically, based on FIGS. 1 to 6, the front surface portion 1, the bottom portion 3, the rear surface portion 4, the cover lid portion 5, and the front lid portion 6 are sequentially connected via the fold line 7.
On the upper edge of the front surface portion 1, locking tongue pieces 8A are extended on both sides of the guide portion 2A formed through the fold 7a.
On both sides of the front surface portion 1, the bottom portion 3, the rear surface portion 4, the cover lid portion 5 and the front lid portion 6 through the crease 17, a main body side wall portion 12 having a front surface sticking piece 11 and a paragraph portion 13, and a rear side wall portion 14 respectively. The side lid 15 and the front lid sticking piece 16 are extended.
[0009]
In the figure, 18 is a zipper wire for excision, 20 is an excision part for opening, 19 is a saw-tooth for cutting a roll film (see FIG. 2), and is attached to the front lid part 6.
As shown in FIG. 3, the front lid sticking piece 16 is stuck to the inside of the side lid portion 15, but its shape is substantially the same as or wider than the front lid portion 6 after removing the cut portion 20. It is necessary to form narrow and long. As described above, when the front lid adhering piece 16 is adhered to the inner side of the side lid portion 15, a trough portion 21 (see FIG. 3) is formed on the inner surface of the side lid portion 15 near the cover lid portion 5, and the locking is performed. This is because the tip of the tongue piece 8A can be locked.
In the figure, reference numeral 10 denotes a notch provided at the lower edge of the locking tongue piece 8A, which ensures the locking of the locking tongue piece 8A to the valley portion 21. Reference numeral 22 denotes a drawer guiding portion provided on the upper edge of the guide portion 2A, which has a corrugated shape so as to make partial contact with the film when the roll-shaped film is drawn, thereby reducing the frictional resistance and improving the drawability. Become. In addition, it is difficult to apply a load or impact to the guide portion 2A due to the reduction of the frictional resistance, it is possible to suppress the occurrence of deformation and distortion, and also to adversely affect the locking function of the locking tongue pieces 8A on both sides. Absent.
[0010]
With respect to the assembly of the present invention, from the unfolded state of FIG. 2, first, the guide portion 2A is folded inward by the fold 7a, and further sequentially through the fold 7, the bottom portion 3, the rear surface portion 4, the cover portion 5 and the front lid portion 6 And the back surface and the front surface portion 1 of the cut portion 20 are spot-bonded to form a square tube. Further, after the roll-shaped film F is installed in a fixed position, the rear side wall portion 14, the front surface sticking piece 11, the main body side wall portion 12, the front lid sticking piece 16, and finally the side lid portion 15 are folded and stuck. Then the carton body is assembled.
[0011]
In use, if the cut-out portion 20 spot-bonded from the zipper wire 18 is cut off, the lid L can be opened and closed as shown in FIG. 3, so that the end of the wound roll film F is picked up. Pull the film to the desired length and close. When the film is drawn out, the entire lower surface of the film is drawn out while being in contact with the upper edge of the guide portion 2A evenly, and is cut by a saw-tooth 19 for cutting provided in the front lid portion 6.
[0012]
In addition, since the site | part which stuck the front cover sticking part 16 to the side cover part 15 has thickness, it will be in the state which the thick part of the front cover sticking piece 16 bulged inside this side cover part 15. In the process of reclosing the lid body L on the container body R, the front end of the front lid adhering piece 16 is bent and deformed slightly with the end of the locking tongue piece 8A extending on both sides of the guide portion 2A. If it slides, and it gets over, it will reach the said trough part 21 and will be locked, and the lid | cover L itself will prevent the unintentional opening.
Further, if the upper edge of the front lid adhering piece 16 is inclined so that the valley portion 21 is gradually wider with respect to the direction of the rear surface portion 4, the locking of the locking tongue piece 8A is somewhat sluggish, Early breakage of the locking tongue 8A due to repeated release and locking can be prevented.
Since the locking tongue piece 8A fits and contacts the paragraph portion 13 of the main body side wall portion 12, it does not collide with the inner surface of the cover lid portion 5 at the time of closing, that is, does not hit, and as a result, the lid L itself No lifting occurs and the lid is properly closed (see FIGS. 4, 5, and 6).
[0013]
As another embodiment, as shown in FIGS. 7 to 12, there is a locking tongue piece 8B instead of the locking tongue piece 8A.
The shape of the locking tongue piece 8B is a semicircular shape, and a straight crease 9a is orthogonal to the base end portion thereof, and an oblique crease 9b is juxtaposed with the guide portion 2A. .
Reference numeral 23 denotes an arc-shaped notch provided near the trough portion 21 of the front lid adhering piece 16, and when the lid is closed, the locking tongue piece 8 </ b> B is internally folded by the straight fold 9 a to form the paragraph portion 13. The covering tongue piece 8B slides while being pressed against the surface of the front lid adhering portion 16, and when it gets over it, it reaches the trough portion 21 and at the same time fits with the arcuate cutout 23. Fits and suppresses opening.
[0014]
Further, the locking tongue piece 8B which is folded and locked with the opening of the lid is not immediately released from the arcuate cutout 23. As the arcuate cutout 23 rises, the locking tongue piece 8B is also lifted, and finally the locking is released when the inner folding is slightly returned. However, a considerable load is applied to the locking tongue piece 8B, resulting in breakage. , Causing deformation.
Therefore, by providing the inclined fold 9b, the load at the time of opening the lid directly applied to the locking tongue piece 8B is to be reduced by the valley fold of the inclined fold 9b. Exhibits a kind of buffering effect that softens the locking resistance.
[0015]
【The invention's effect】
According to the present invention having the configuration as described above, the following effects are brought about.
That is, according to the first aspect of the present invention, the roll-shaped film F can be prevented from jumping out, and the locking tongue piece 8A can be engaged with the valley portions 21 formed at the top inner corners on both sides of the lid L. In addition, the lid can be reclosed properly and reliably, and dust, pests, etc. can be prevented from entering when not in use.
[0016]
According to the second aspect of the present invention, the roll-shaped film F can be prevented from popping out, and the locking tongue piece 8B has a kind of buffering effect that suppresses unintended opening and softens the resistance at the time of opening. Thus, the locking tongue piece 8B is prevented from being deformed or damaged, and the locking function is maintained for a long time.
[0017]
According to the third aspect of the present invention, by attaching the drawer guiding portion 22 to the guide portion 2A, it is possible to effectively prevent the roll-shaped film F from popping out, and the frictional resistance can be reduced by partial contact therewith. The film F can be pulled out smoothly. In particular, in the case of a food packaging wrap film made of polyvinylidene chloride as the main ingredient, it has adhesiveness and self-adhesiveness, so that distortion is generated as much as possible without causing wrinkles while contacting the entire upper edge of the guide part 2A It has been required to be careful to draw and cut a desired amount without making it, but can be easily performed by the partial contact.
Further, since the load and impact on the guide portion 2A are less likely to be applied due to the reduction of the frictional resistance, the locking function is maintained for a long time without adversely affecting the locking function of the locking tongue pieces 8A and 8B. .
