Description

  The present invention belongs to the technical field of cartons made of paperboard, and more particularly relates to a shaker carton that can store and dispense granular confectionery such as chocolate, candy, and gum, and other granular products.

  Conventionally, as a carton having such a swinging function, a side surface or a top panel provided with a swing outlet is generally used (see Patent Documents 1 and 2). However, since only such a type has limitations in terms of design, there is also known one provided with a swing outlet in the front (see Patent Document 3).

JP-A-7-76341 JP 7-89538 A Utility Model Registration No. 3060032

  The carton with a shaker described in the above-mentioned Patent Document 3 is a type in which a shaker is provided on the front surface, and it can be automatically assembled and packaged by placing it on a sack pasting machine which is a general-purpose box making machine. A broken piece is provided on the side panel to be bonded to the bonded panel, and a broken piece bonded portion is formed by two perforations or a zipper at a position where the broken piece is bonded in the bonded panel. Since the locations are dispersed, it is necessary to shoot and apply the paste to the dispersed locations, and there is a problem that it cannot be applied at a high speed as in the case of single coating. In addition, since the inscribed panel that slides to open and close the front panel swing outlet is T-shaped, it tends to bend in the blanking process, and if you try to prevent this, there will be a problem that the speed will drop. The machine suitability is not so good.

  In addition, since the carton with a swing outlet has guide pieces for the inscribed panel, a large number of flaps are folded on the filling line, so that a dedicated jig is required. In other words, if the current filling line is used as it is, the top panel on the front panel side and the guide piece on the inscribed panel will be bent at the same time. It will be visually recognized and is not preferable in appearance.

  Further, the carton with a shaker described in Patent Document 3 has a concern that the side surface of the finger-hanging part is opened at the time of opening, and there is a concern that if the contents are small particles, it will come out from there. Since the panel is large, it is supported by the upper and lower guide pieces, but there is also a structural problem that it is bent and difficult to move smoothly.

  The present invention has been made in view of the above-described problems, and the object is to use the current filling line as it is with excellent mechanical suitability for a sack pasting machine while having a swing outlet in the front. It is another object of the present invention to provide a carton with a swing outlet which can be used and has no structural problems such as spillage or poor operability.

  In order to achieve the above object, a carton with a shaker according to the present invention is a rectangular parallelepiped carton formed by assembling a single blank, and includes a front panel, one side panel, and a rear panel that are continuously arranged in the lateral direction. The panel, the other side panel, the front side inner panel, and the side side inner panel form a rectangular tube-shaped body with the front panel and one side panel overlapping on the outside of the front side inner panel and the side side inner panel. At the top of the inner panel, a swing outlet is provided near one side panel, and a slit in the vertical direction is formed in the middle. The upper part of the front panel has a width that can be inserted into the slit of the front inner panel. The opening region of the opening portion is partitioned in a breakable manner, and an opening is provided near the other side panel in the opening region. The opening area connected to the opening area of the flannel is divided so as to be broken, and the opening area of the front panel is opened together with the rotation area of one side panel connected to the opening area, and then opened from the front panel. By sliding with the front end of the front panel inserted into the slit on the front inner panel, the opening of the front panel overlaps or shifts from the outlet of the front inner panel, so that the outlet opens and closes. It is characterized by.

  And in the carton with a shake outlet of the said structure, it is preferable to provide the stopper which prevents slipping out from the slit of a front inner side panel at the front-end | tip of the opening / closing area | region of a front panel.

  Moreover, in the carton with a shake outlet of the said structure, it is preferable to provide a vertical broken line in the middle of the opening / closing area | region of a front panel.

  Further, in the carton with a swing outlet having the above-described configuration, it is preferable that the opening of the opening / closing region of the front panel is an elliptical shape with an inclined axis.

  While the carton with a shaker of the present invention is a type in which the shaker is located on the front, when assembling, the lower back side from the unsealed area of the front panel may be bonded to the front side of the front inner panel and opened. When the sack is applied, only one paste can be applied in a line on the front side of the front inner panel and bonded at a high speed, so that the machine suitability for the sack application machine is excellent. Further, the upper and lower closing parts do not have a special flap like a guide piece, and are the same closing parts as those in a normal carton, so that they can be assembled using the current filling line as they are. In addition, since the holes such as the finger-hanging parts are not formed even when opened, the contents do not spill out, and after opening, the opening / closing area in which a part of the front panel is broken is simply inserted into and removed from the slit. Therefore, the opening / closing operation of the swing outlet can be performed smoothly.

  In the carton with a swing outlet configured as described above, by providing a stopper that prevents the front inner panel from coming out of the slit at the front end of the front panel opening / closing area, the opening / closing area is prevented from being detached from the slit, and the fingertips are shaken. The opening and closing operation of the exit can be performed with confidence.

  Further, in the carton with a swing outlet having the above-described configuration, by providing a vertical fold line in the middle of the opening / closing area of the front panel, the opening / closing area bends at the fold line when sliding, and has an opening on the tip side from the fold line. The part can be kept in a straight state and slid to perform a stable opening / closing operation.

  Further, in the carton with a swing outlet having the above configuration, when the opening / closing region slides, the opening of the opening / closing region of the front panel is made into an elliptical shape with an inclined axis, compared to a circle or an ellipse where the axis is not inclined. Bending at the opening is reduced.

It is a perspective view which shows an example of the carton with a shake outlet which concerns on this invention. It is an expanded view of the blank which forms the carton with a shaker of FIG. It is a perspective view shown in the state which opened the carton with a shaker of FIG. It is a perspective view shown in the state where it reclosed after opening the carton with a shaker of FIG. It is a perspective view which shows the carton with a shaker at the time of use shown in FIG. 4 in the state which opened the shaker.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  The carton C with a shaker shown in FIG. 1 is formed by assembling the unfolded blank B shown in FIG. In this carton C with a swing outlet, granular confectionery such as chocolate, candy, and gum and other granular products are stored.

  Blank B is formed by punching paperboard, and as shown in FIG. 2, front panel 1, right side panel 2, rear panel 3, left side panel for constituting the trunk of carton C with swing outlet 4, the front inner panel 5 and the side inner panel 6 are continuously provided in the horizontal direction. The wide front panel 1, the rear panel 3, and the front inner panel 5 have substantially the same width. The narrow right side panel 2 and the left side panel 3 have the same width, and the side inner panel 6 is slightly narrower than the right side panel 2 and the left side panel 3. It is just extended.

  In order to close the upper part of the trunk of the carton C with a swing outlet, folding pieces 7 and 8 are connected to the upper sides of the right side panel 2 and the left side panel 4, respectively, and an inner closing panel 9 is provided on the upper side of the rear panel 3. An outer closing panel 10 is continuously provided on the upper side of the front inner panel 5, and in order to close the lower part of the body part, folding pieces 11, respectively are provided on the lower sides of the right side panel 2 and the left side panel 4. 12, an inner closing panel 13 is connected to the lower side of the rear panel 3, and an outer closing panel 14 is connected to the lower side of the front panel 1. Since the right side panel 2 and the side inner panel 6 overlap at the time of assembly, the folding piece 7 provided on the upper side of the right side panel 2 may be provided on the upper side of the side inner panel 6.

  In the upper part of the front inner panel 5, a swing outlet 15 is provided near the side inner panel 6, and a vertical slit 16 is formed in the middle. The swing outlet 15 is formed in a state where it hangs on a part of the boundary line as shown in the figure so that the edge does not bulge outward when the front inner panel 5 and the side inner panel 6 are bent at the boundary between them.

  In the upper part of the front panel 1, an opening region 1 a having a width that can be inserted into the slit 16 of the front inner panel 5 is partitioned so that it can be broken, and an elliptical opening 17 is provided near the edge of the opening region 1 a. In the upper part of the right side panel 2, a turning area 2a connected to the opening area 1a of the front panel 1 is partitioned so as to be broken. Here, the opening area 1a of the front panel 1 can be broken by a cut line having a jumper portion at two places on the left side, and the lower side of the rotation area 2a of the right side panel 2 has a jumper portion at one place in the middle. The boundary with the upper folding piece 7 is a cut line and can be broken at the perforations. In the middle of the boundary between the opening area 1a and the rotation area 2a, a cut line 18 slightly protruding toward the opening area 1a is formed.

  The opening area 1a of the front panel 1 has the same lateral width as that of the rear panel 3 and the front inner panel 5, but slightly protrudes to the left by reducing the width of the portion below the front panel 1 It has a different shape. And the protrusion 1b which functions as a stopper is formed in the front-end outer side of the opening-and-closing area | region 1a by setting it as the shape where the upper side left side of the front panel 1 was slightly depressed in parallel.

  Furthermore, the open / close region 1a of the front panel 1 is provided with a polygonal line 19 made of vertical ruled lines so as to be longitudinally cut in the middle. The broken line 19 is provided so that the open / close region 1a bends in two when in use, and is provided on the right side of the opening 17 and not in contact with the opening 17.

  The opening 17 provided in the open / close region 1a is not limited to an elliptical shape, but in the case of an elliptical shape, an elliptical shape with an inclined axis is preferable. As shown in the figure, by tilting the major axis of the ellipse slightly obliquely from the vertical direction, the open / close region 1a is prevented from being bent at the opening 17 when a force is applied in the width direction.

  In order to assemble the blank B shown in FIG. 2, the blank B is first sack pasted on a general-purpose sack pasting machine. Specifically, while conveying the blank B in the vertical direction of the figure, it is folded at the boundary between the left side panel 4 and the front inner panel 5 and then passes under the nozzle that is blowing glue, as shown in the figure on the front inner panel 5. After only one paste is applied in a line shape to the bonding part 5a, it is bent at the boundary between the right side panel 2 and the rear panel 3, and the lower back side of the front panel 1 is bonded to the front side of the front inner panel 5 from the opening region 1a. . A plurality of blanks B folded in the sack pasting state are collectively sent to the filling step, and the contents are put there to assemble the carton C with a shaker shown in FIG.

  In the filling process, the front B 1 is folded by the front panel 1, the right side panel 2, the rear side panel 3, the left side panel 4, the front inner panel 5 and the side inner panel 6 5 and the side inner panel 6 are formed with a rectangular tube-shaped body portion in which the front panel 1 and the right side panel 2 overlap each other.

  Next, the folding pieces 7 and 8 connected to the upper sides of the side panels 2 and 4 are bent inward, and the upper side of the inner side closing panel 9 and the upper side of the front inner panel 5 are connected to the upper side of the rear panel 3 from above. The outer closing panel 10 to be provided is sequentially folded and glued to form a closing portion at the upper portion of the trunk portion. Thus, after closing the upper part in a rectangular tube-shaped trunk | drum, the content is inserted from lower opening. Then, the folding pieces 11 and 12 connected to the lower side of the side panels 2 and 4 are bent inward, respectively, and the inner closing panel 13 connected to the lower side of the rear panel 3 and the lower side of the front panel 1 are provided from above. The outer closing panel 14 is sequentially bent and glued to form a closing portion at the lower portion of the body portion, thereby completing the assembly of the carton C with a shaker shown in FIG. The order of closing the upper part and the lower part may be reversed.

  When the contents are shaken out from the carton C with a swing outlet shown in FIG. 1, first, as shown in FIG. 3, the opening area 1a of the front panel 1 is broken together with the rotation area 2a of the right side panel 2 and opened. To do. Thereafter, as shown in FIG. 4, the front end of the unsealed region 1 a separated from the front panel 1 is inserted into the slit 16 of the front inner panel 5 and reclosed. In this way, by breaking the opening area 1a as an opening piece from the front panel 1 and also breaking the rotation area 2a of the right side panel 2 connected thereto, the carton C with the outlet in FIG. The tip of the unsealed region 1a, which is the unsealed piece, is inserted into the slit 16 of the front inner panel 5 to prepare for the contents to be dispensed.

  After preparing the contents in this way, when the fingertip is put on the protrusion 20 formed by the cut line 18 at the boundary between the opening area 1a and the rotation area 2a and the opening area 1a is slid to the right side, As shown in FIG. 5, since the opening 17 of the front panel 1 is overlapped with the outlet 15 of the front inner panel 5 and the outlet 15 is opened, the contents can be extracted therefrom. As described above, when the open / close region 1a is slid left and right with the fingertip, the opening 17 of the open / close region 1a overlaps or shifts and the swing opening 15 is opened and closed.

  In the carton C with a swing outlet, the protrusion 1b is provided at the tip of the opening / closing area 1a. Therefore, when the opening / closing area 1a is slid to the left and right, the protrusion 1b is hooked at the tip of the slit 16 to serve as a stopper. Thus, the unsealed region 1a is prevented from being pulled out from the slit 16 of the front inner panel 5.

  Further, since the carton C with a swing outlet has a vertical fold line 19 provided in the middle of the opening / closing area 1a, it is bent in two at the fold line 19 as the opening / closing area 1a slides to the right. Thus, the portion having the opening 17 on the tip side from the polygonal line 19 can slide while maintaining a straight state.

  Further, in the carton C with an outlet described above, an opening 17 for overlapping the outlet 15 is provided in the opening / closing area 1a, and although this is weak in strength, the opening 17 of the opening / closing area 1a has an axis line. Since the tilted elliptical shape is used, the bending of the opening / closing region 1a when the opening / closing region 1a slides is reduced as compared with a case where the opening 17 is circular or an ellipse whose axis is not tilted.

  As mentioned above, although the form for implementing this invention has been demonstrated in detail, the carton with a shaker outlet by this invention is not limited to said form at all, and various in the range which does not deviate from the meaning of this invention. Of course, changes are possible.

  For example, in the above example, the front panel open / close region is slid rightward and is designed to be taken in and out of the slit on the front inner panel. It is also possible to design such that the open / close region slides leftward and out of the slit on the front inner panel.

  In the above example, the protrusion 1b functioning as a stopper is formed outside the front end of the opening / closing area 1a in the front panel 1, but the protrusion is formed inside the front end by devising the shape of the cut line that can break the opening / closing area 1a. You may make it form. Of course, it is also possible to form both the outer side and the inner side of the open / close region 1a.
