[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dispensing carton that can easily take out granular products from the side of the carton.
[0002]
[Prior art]
This type of dispensing carton is generally a rectangular parallelepiped carton having a size that can be easily held with one hand, and in each case, a dispensing opening is provided on the side of the carton, from which a granular product can be easily taken out.
For example, Japanese Utility Model Publication No. 54-22503 proposes a swinging carton 30A as shown in FIG. 5, and a guide connected to a rotating piece F that functions as a palate covering the swinging opening M. It rotates according to the board G and repeats opening and sealing.
The forming principle of the swinging carton 30B proposed in Japanese Patent Application No. 7-117701 shown in FIG. 6 is the same as that described above, but a hooking piece K is further extended at the end of the guide plate G. The rotation angle of the rotation piece F is widened, and at the same time, the locking when fully opened is made firm.
[0003]
[Problems to be solved by the invention]
However, the proposal of Japanese Utility Model Publication No. 54-22503 shown in FIG. 5 is only 60 ° stopped as shown in FIG. 5B even if the rotating piece F is opened to the maximum, and in this state, it rotates when it is swung out. There is a problem that the piece F is obstructive and difficult to swing out.
An improvement of this point is proposed in Japanese Patent Application No. 7-117701 shown in FIG. 6, in which a stop piece K is extended at the front end of the guide plate G, and the rotating piece F is arranged at a wider angle. I want to open it. Although this proposal certainly solves the problem of widening the angle, there is a troublesome problem that the guide plate G must be folded back and the hooking piece K provided at the tip of the guide plate G must be folded along the side plate 3 during carton molding. is there.
The present invention has been made in view of the above-mentioned problems, and can be easily assembled from a one-piece blank without taking any trouble at the time of molding. An object is to provide a swing-out carton that makes it easy to take out an object and that a rotating piece locks around the opening when resealed.
[0004]
[Means for Solving the Problems]
The dispensing carton according to the present invention, which has been made to solve the above problems, has a cylindrical shape in which a glue margin, a front plate, a first side plate, a rear plate, and a second side plate are connected in this order via a broken line, and are bonded to a cylinder. In the carton formed by folding the head and bottom flaps connected to the upper and lower sides of the body part via the folding line, the rotating piece is connected to the upper side of the second side plate via the folding line, A fin-shaped guide plate is extended on the upper side of the rotating piece so as to protrude upward through a fold line, and a fold line that obliquely crosses the rotating piece from the upper side corner of the second side plate of the rotating piece is provided. The guide plate is inserted so as to slide between the head flaps, and the fold line crossing obliquely provided on the rotating piece is provided in the upper portion of the front plate along the adhesive margin. By bending, the rotating piece opens at an angle of 90 degrees or more. A shaken carton, characterized in that the it was Noh, also the shaken during re-closure of the opening, the a shake-out opening only petals projecting tabs provided at the middle of the rotating piece covering the palate The rotating piece is pushed inward from the front plate and the rotating piece is locked to the front plate.

DETAILED DESCRIPTION OF THE INVENTION
The swing carton of the present invention will be described below in more detail with reference to the drawings.
The swing-out carton according to the present invention may be a sealed end carton having a head portion and a bottom portion formed by adhesive bonding, or an insertion velcro carton. The following description is based on the sealed end carton.
FIG. 1 is a blank development view of a dispensing carton according to the present invention.
A carton blank 10 of a dispensing carton according to the present invention has an adhesive margin 5, a front plate 1, a first side plate 2, a rear plate 3, and a second side plate 4 connected in this order via folding lines a to d, and the upper pieces thereof. The head flaps F1 to F4 and the bottom flaps B1 to B4 are connected to the lower side via folding lines e and f.
A rotating piece 6 is connected to the upper side of the second side plate 4 through a fold line g, and a fin-shaped guide plate 7 is extended from the upper side so as to protrude upward through a fold line i. ing.
The point of the present invention is that a folding line h that obliquely crosses the rotating piece 6 from the upper side corner of the rotating piece 6 on the second side plate 4 side is provided, and the rotating piece 6 is divided into 6A and 6B. And the part which consists of a guide piece 7 is bendable in two steps with the fold line h and the fold line i.
On the other hand, a swing opening 8 is punched out along the adhesive margin 5 at the top of the front plate 1. Further, a protrusion piece R is provided in the middle of the turning piece 6 to lock the turning piece 6 around the opening 8 when resealed.
[0006]
In order to form the swinging carton according to the present invention from the blank having the above structure, the blank 10 is first folded in three at the folding lines b and d, and pasted with a sack, the glue margin 5 and the second side plate 4 are glued, and the flat A simple folding carton is formed and supplied to the user in that state. A user raise | generates this and makes it cylindrical shape, What is necessary is just to shape | mold the remaining edge part after filling the contents, after shape | molding one end part of a head part or a bottom part. In this case, the head may be formed by folding the sub flaps F1 and F3, then folding back the guide plate 7 and finally folding the main flaps F2 and F4 and gluing them together between the main flaps F2 and F4.
[0007]
Next, the function of the swing carton according to the present invention will be described with reference to FIGS.
FIG. 2 is a perspective view of a dispensing carton according to the present invention, and FIG. 3 is a front view of a dispensing outlet. Here, the “swing opening” includes a swing opening 8 and peripheral parts such as a guide plate.
FIG. 2A is a perspective view of the swinging carton when fully opened,
The opened state shown in FIG. 2 (a) is obtained by placing a finger on the side of the rotating piece 6 that covers the swing opening 8 of the unopened swing opening shown in FIG. 3 (a) and that functions as a palate. In this state, the angle is rotated (swing) until the angle with the front plate 1 is approximately 60 °. This state is substantially the same angle as the dispensing outlet formed by the conventional dispensing carton. However, the swinging carton 20 according to the present invention can rotate the rotating piece 6 at a wider angle from here. FIG. 2B shows a state in which the rotating piece 6 is rotated to an angle slightly larger than 90 °, and this state is also shown in FIG. 3B.
Such a wide angle can be achieved by bending the rotating piece 6 at a fold line h. In the state shown in FIGS. 2B and 3B, the leading end of the guide plate 7 is also slightly bent at the intersection with the upper side of the front plate 1, and the guide plate 7 is inside as shown in FIG. Inclined to. In this state, the granular material is easily extracted. That is, the granular material that has exited the opening 8 without the tilting carton 20 being greatly tilted is aligned in a substantially constant direction with the folded wall formed by the rotating pieces 6A and 6B and the guide plate 7 serving as a guide plate. It is possible to easily extract only the desired quantity.
FIG. 2 (c) shows a state of being rotated by approximately 135 °. In this state, the rotating piece 6 is too open, and the guide plate is also tilted inward, so that the above-mentioned good guide plate is obtained. It is hard to fall. Therefore, the shape of the guide plate 7 that also functions as a stopper is locked so that the tip S of the guide plate is engaged with the upper end of the second side plate 2 so that the rotating piece stops in the vicinity of 110 ° to 120 ° and does not rotate further. Just design.
[0008]
Further, since the rotating piece 6 rotates using the folding line g as a hinge, it is preferable to make the folding line g a lead rule (a broken line having a broken line on the ruled line) to reduce folding resistance. Further, it is preferable that the fold line i connecting the opening piece 6 and the guide plate 7 and the fold line h bending the opening piece 6 be lead rules.
[0009]
When the unopened outlet shown in FIG. 3 (a) is opened and the opened carton 20 opened as shown in FIG. 3 (b) is resealed, as shown in FIG. When the moving piece 6 is lightly pushed in, only the petal-like protruding piece R provided at the edge of the turning piece 6 is pushed inward from the front plate 1 and the whole outlet is locked, so that the outlet is inadvertently Never open.
[0010]
When the unopened swinging carton 20 shown in FIG. 3A or the resealed swinging carton 20 shown in FIG. Can be formed. If the edge portion protrudes slightly from the first side plate 2 within a range that does not hinder the distribution of the dispensing carton 20, it becomes easier to open. The range is preferably 0.5 to 1.5 mm.
Further, since the guide plate 7 slides with the head flap, a frictional resistance is generated. For this reason, it is also possible to keep the swinging outlet in an appropriate half-open state.
[0011]
A wide range of paperboard can be used for the drawer carton substrate according to the present invention. However, if opening and closing is repeated over a long period of time, breakage occurs from the locking portion S and the protruding piece R of the guide plate 7 described above, and the locking at the time of full opening and closing is loosened, or the guide plate 7 does not lock. There is a possibility of getting out.
To prevent this, the use of tough paperboards such as special board or card type is preferable, and plastic films such as polyvinyl chloride, polypropylene, polyethylene, polyethylene terephthalate, polycarbonate, polystyrene, etc. are laminated on the paperboard. May be. In addition, this laminate can improve moisture resistance.
[0012]
In addition, any technique such as offset, gravure, and silk screen may be used for printing on the paperboard. Further, post-processing such as embossing, foil stamping, and OP varnish coating may be performed to such an extent that the carton molding and the opening / closing function of the outlet are not impaired.
Further, since the drawer carton according to the present invention does not have a sealing property as it is and does not have a function of preventing mischief, it is preferable to overlap the whole of the drawer carton 20 with a shrink film or a moisture-proof plastic film after molding and filling.
[0013]
【Example】
An example sample having an internal volume of 45 ml was manufactured using a special plate, Ultra H, manufactured by Daishowa Paper Co., Ltd., 260 g / m ² in accordance with the example dimension specification diagram of FIG. A trial carton shown in FIG. 5 was made, filled with granulated chocolate, and the suitability of the carton carton was tested by 10 panelists.
In the case of the embodiment, since the rotation angle of the rotating piece that also serves as the palate exceeds 90 °, the contents can be taken out without greatly tilting the swinging carton 20 and the presence of the guide plates 6A and 6B and the guide plate 7 exists. As a result, the direction of the swing was stabilized, and the contents could be taken out in an aligned state.
In the comparative example, locking of the rotating piece 7 at the time of resealing could not be performed, but in the example, the rotating piece 7 can be easily locked to the periphery of the opening simply by pressing the rotating piece 7 with a fingertip, and the contents spilled inadvertently. I didn't get out.
Also, carton molding is easier than conventional swing cartons, and can be diverted by slightly improving conventional molding and filling machines.
[0014]
【The invention's effect】
According to the dispensing carton according to the present invention, a guide plate for taking out can be formed with a rotating piece and a guide piece that opens at a wide angle at the dispensing outlet, and the contents can be taken out with good directivity even if the carton is not greatly inclined, Moreover, there is no fear that the outlet is locked when fully opened and re-sealed, so that the outlet is not dropped or unintentionally opened, and the outlet can be stopped at any half-open position.
Furthermore, in the case of a shield carton, the area used for the paperboard is small, and the machine sticking process can be performed more easily than the conventional swing carton, so that it can be provided at an economical cost.
