BACKGROUND OF THE INVENTION
The present invention relates to a dispensing carton for taking out granular contents from a swinging outlet of an inner box slidably accommodated in a cylindrical body (exterior sleeve).
[0002]
[Prior art]
The carton is always placed in a pocket, etc., and when necessary, the outlet can be opened to take out an appropriate amount of content, and the outlet can be returned to the original closed state again. Is used.
There are various types of dispensing cartons. As a typical one used conventionally, there is a dispensing carton composed of an inner box and a cylindrical body.
For example, as shown in FIG. 6, a drawer carton (portable paper box) 80 disclosed in Japanese Patent Application Laid-Open No. 9-286431 has a prismatic cylindrical body 70 and a rectangular parallelepiped inner box 60 that slides inside thereof. 6 and stops the movement of the inner box 2 at the swinging position shown in FIG. 6 (b) where the swinging outlet (not shown) is fully opened by the shortest movement from the storage position shown in FIG. 6 (a). A kind of locking means has been proposed. As shown in FIG. 6B, the first locking means is formed by extending the edge 33 of the window 32 provided on the bottom plate 31 of the cylindrical body 70 and the rear plate 21 of the inner box. The second locking means is provided on the bottom plate 31 of the cylindrical body 70 and the locking tongue piece provided on the bottom plate of the inner box, although illustration is omitted. This is due to the locking with the folded piece provided.
Moreover, the locking means which prevents the movement of the middle box in the reverse direction also functions at the storage position of the middle box.
[0003]
[Problems to be solved by the invention]
However, the first locking means in the swinging position of the swinging carton disclosed in Japanese Patent Application Laid-Open No. 9-286431 does not have a sufficient locking force, and further forward (in the direction of the arrow) depending on how the force is applied. There is a possibility that the inner box 60 will fall off. This is because the protruding piece 23 is easily bent and the locking itself is unstable because it is performed at the center of the bottom plate 31 of the wide tubular body 70 that is easily bent. Moreover, there is also a problem that the protruding piece 22 becomes fatigued and the locking force becomes insufficient when used repeatedly.
Although the principle of the first locking means is not shown, it is also used for preventing backward sliding in the storage position, but there is a possibility that the inner box 60 falls off in the opposite direction due to some beat.
Further, the second locking means has a sufficient locking force, but the bottom side of the inner box 60 and the cylindrical body 70 must be wide to lock the locking tongue piece and the folded piece. In addition, there is a problem in that it becomes a dispensing carton that is thicker than necessary, and part of the blank of the cylindrical body 70 protrudes to form the folded piece, which increases the material cost.
The present invention has been made in view of the above-described problems, and provides a compact and economical ejection carton where the inner box is securely locked at the storage position and the ejection position, and there is no fear of falling off the cylindrical body. With the goal.

[0009]
FIG. 3 is a perspective view and a function explanatory diagram of a dispensing carton as a reference example . In order to explain the function of the dispensing carton 50 as a reference example in an easy-to-understand manner, the inner box 30 is indicated by a solid line and the cylindrical body 40 is indicated by a dotted line in FIG. FIG. 3A shows that after the inner box 30 is inserted into the cylindrical body 40 and the contents are filled from the front open end of the inner box 30, the small flaps 1-1 and 3-1, the front plate 2-1. The assembly state of the swing carton 50 according to the present invention in which the front open end is sealed with the insertion piece 2-2 is shown, and the storage position of the inner box 30 is shown. Usually, the filled carton 50 according to the present invention is further distributed and sold by being overlapped with a transparent plastic film. FIG. 3B shows a swinging position where the inner box 30 is pushed forward with a finger through the operation window 16 and slid to a predetermined position, and the swinging outlet 6 is opened. After a suitable amount of content has been shaken out at this position, the inner box 30 can be pushed back to the storage position shown in FIG.
[0010]
The most characteristic point in FIG. 3 is that the folded piece 5 folded on the side plate 1 slides in the gap formed by the side plate 1 of the inner box 30 and the side plate 15 of the cylindrical body 40. Is limited to the region of the notch 17 of the locking plate 11.
That is, in the storage position of the inner box 30 shown in FIG. 3 (a), the first locking means by the bent portion A1 of the folded piece 5 and the rear end edge B1 of the notch 17 functioning as a stopper are locked. Thus, the rearward sliding of the inner box 30 is prevented, and the edge A2 of the folded piece 5 and the front edge B2 of the notch 17 functioning as a stopper are locked at the swinging position shown in FIG. Thus, the second lock means prevents the inner box 30 from sliding further forward. In FIG. 3, a circle indicates a state in which the first lock means and the second lock means are functioning.
The first and second locking means are based on the engagement between the edges of the carton base material or between the edges and the bent portions, and the engagement by these is extremely strong. When fitted into the notch 17, the sliding of the inner box 30 cannot slide beyond a predetermined width (difference between the front-rear width of the notch 17 and the front-rear width of the folded piece 5). Therefore, there is no fear that the inner box 30 falls backward or slides more than necessary beyond the swing position.
[0011]
3A, the side surface of the protruding piece A4 provided at one end portion in the longitudinal direction of the rear plate 2-3 of the inner box 30 and the rear open end portion of the tubular body 40 are provided. The fourth locking means by locking the end edge B4 (the side plate 15 and the end edge of the locking plate 11) prevents the inner box 30 from inadvertently and independently starting to slide. Yes.
You may make it provide this 4th locking means in the both ends of the longitudinal direction of the backplate 2-3.
Since the fourth locking means is based on the locking between the side surface of the protruding piece A4 and the rear open end B4, the locking force is weaker than that of the first and second locking means described above. When the middle box 30 is slid through, a certain amount of resistance is shown, but the lock is easily released.
Further, since the inner box 30 is a hollow body, when the inner box 30 returns to the storage position, the protruding piece A3 is repelled by the rear open end B3 and makes a sound, so that the return to the storage position is transmitted to the finger. Along with the sound, it can be confirmed.
[0012]
You may make it provide further the 3rd locking means which supplements the above-mentioned 1st locking means (A1 / B1). As shown in FIGS. 3 (a) and 3 (b), the side surface of the protruding piece A3 provided by extending the longitudinal end of the front plate 2-1 of the inner box 30 and the front side of the tubular body 40 are provided. This is because the edge B3 (the side plate 15 / the locking plate 11 and / or the front edge of the side plate 13) of the open end is locked. By this third locking means, the rearward sliding prevention of the inner box 30 is further complete.
The fourth locking means plays an important role in place of the first locking means instead of the supplementary means when the first locking means cannot be formed as will be described later.
[0013]
When starting the sliding of the middle box 30 of the swing carton 50 according to the present invention, the finger is pressed against the portion of the top 2 that is looking through the operation window 16 with the strength to overcome the locking force of the third lock. , Push forward. Therefore, in order to improve the operability, the finger pressing part of the top plate 2 is roughened by a method such as embossing or half-cutting in a mesh shape, or partial printing with rubber-based ink is performed. It is preferable to apply anti-slip processing on the surface.
[0014]
The point of the present invention resides in the sliding range regulating means of the inner box 30 by the first locking means and the second locking means described above, and the combination form of the folded piece 5 and the notch 17 for realizing this has been described above. The following variations are possible without being limited to the dispensing carton 50. FIG. 4 is a supplementary explanatory view of the first and second locking means of the dispensing carton as another reference example . FIG. 4 shows a case where the locking means is formed along the side plate side 1. As shown in FIG. 4 (a), the folded piece 5 formed by punching out a part of the bottom plate 4 is inserted into the notch 17 having both stoppers in the front and back in a state where the folded piece c is folded 270 ° on the side plate 1 along the folding line c. You may do it. As shown in FIGS. 4B and 4C, when the rear side of the inner box 30 is molded, the small flap 1-2 to be folded inward is folded 180 degrees on the front side, Alternatively, it may be inserted into the notch 17 'having a stopper. However, in this case, since the means for the second lock has been lost, this may be compensated by the fourth lock. FIG. 5 is a supplementary explanatory view of the first and second locking means of the swing carton according to the present invention. FIG. 5 shows a case where the locking means is formed along the bottom plate 4 side. As shown in FIG. 5 (a), the end of the bottom plate 4 is extended to form a folded piece 5, which is formed on the lower plate 14 side in a state of being folded on the 180 ° bottom plate side, and has notches with stoppers on both sides. 17 may be inserted. However, in this case, it is necessary to slightly change the configuration of the blank 10 of the inner box shown in FIG. Further, as shown in FIGS. 5 (c) and 5 (d), a notch having a stopper only on one side in a state where a part of the insertion piece 2-4 to be inserted inside the inner box 30 is folded to the front side of the bottom plate 4. 17 'may be inserted. However, in this case, since the means for the second lock has been lost, this may be compensated by the fourth lock.
[0015]
A wide range of paperboard can be used for the blank base material of the drawer carton of the present invention, but a card system and a special board system that have rigidity and strong folding strength can be suitably used. In addition, when the opening and closing of the outlet is repeated for a long period of time and the number of times of opening and closing increases, polyvinyl chloride, polypropylene, polyethylene, polyethylene terephthalate, polycarbonate, polystyrene, etc. The film may be laminated to paperboard. In addition, this laminate can improve moisture resistance. Furthermore, instead of paperboard, a plastic sheet may be used for the blank substrate. For example, a polypropylene sheet made of an opaque material mixed with a filler such as talc or an amorphous polyethylene terephthalate sheet can be used as it is as a blank substrate. Further, depending on the contents, a transparent plastic sheet may be used to form a skeleton type that shows the contents.
[0016]
Any known printing method such as offset, gravure and silk screen may be used for printing on the blank substrate. Further, post-processing such as embossing, foil stamping and OP varnish coating may be performed. Since these printing and post-processing are processing in the form of a paperboard or plastic sheet, a beautiful, powerful and sharp finish is obtained. Note that the swinging carton according to the present invention does not have a sealing property, and it is preferable to overlap the entire swinging carton with a moisture-proof plastic film after molding and filling in order to prevent dust from being mixed.
[0017]
