  The sliding carton of the type described above is designed to pull out the container body from the sleeve and take out the contents. Therefore, when the whole is made into a slender shape and, for example, granular confectionery is arranged in a line, It is convenient because it can be taken out one by one. However, when the container body is pulled out and tilted to take out the contents, the contents come out one after another so as to flow, and there is a problem that it is difficult to reliably take out the contents one by one. In addition, if the contents are resealed in the middle of not taking out all the contents, the contents will become unstable in the carton when being carried, and there will be a problem that the contents may be damaged depending on the contents. .

  The present invention has been made in view of such a problem, and the object of the present invention is to reliably take out the granular contents one by one, and even in the middle of not taking out all the contents, The object is to provide a sliding carton that does not stick.

In order to achieve the above object, the sliding carton according to the present invention is:
Consists of a rectangular tube-shaped sleeve with both front and rear ends open, a tray-like container body slidably inserted into the sleeve, and a rectangular parallelepiped member set within the container body,
The sleeve is formed with a notch in the length of one stroke on the rear side of the sleeve so that the container body can be pulled out of the sleeve by one stroke that can take out only one granular content. The main body is provided with a protruding piece for contacting the front side end of the sleeve at the front end of the container main body, and a protruding piece for contacting the notch portion of the rear side of the sleeve at the rear end. Provided,
The rectangular parallelepiped member has a locking piece with the front side as a fulcrum on the lower surface of the rectangular parallelepiped member, and has a protruding locking piece on the upper surface, and the container body is engaged with the locking piece on the lower surface of the rectangular parallelepiped member on its inner bottom. The plurality of locking portions are arranged in the front-rear direction at regular intervals, and the sleeve has a plurality of locking portions for engaging the protruding locking pieces on the upper surface of the rectangular parallelepiped member with the sleeve ceiling at the regular intervals. Are arranged side by side,
In a state where a plurality of granular contents are stored side by side on the front side of the rectangular parallelepiped member positioned at the rear, the locking piece on the bottom surface of the rectangular parallelepiped member engages with the locking portion on the bottom of the container body, and the protrusion on the upper surface of the rectangular parallelepiped member The stopper piece is not engaged with the locking portion of the sleeve ceiling, and when the container main body is pulled out from the sleeve from this state, the locking piece on the lower surface of the rectangular parallelepiped member is engaged with the locking portion of the inner bottom of the container main body. The container body moves forward together with the rectangular parallelepiped member and the granular content by one stroke, and the protruding locking piece on the upper surface of the rectangular parallelepiped member operates so as to engage with the locking portion in front of the sleeve ceiling. When the container main body is pushed into the sleeve after one content is taken out, the rectangular parallelepiped member and the remaining granular contents remain in the container main body while the protruding locking piece on the upper surface of the rectangular parallelepiped member is engaged with the locking portion of the sleeve ceiling. Move forward by one stroke Wherein the rectangular parallelepiped member lower surface of the locking piece is operated to engage the engagement portion of the front one in the container body bottom.

By forming the notches 24a continuously, when the blank is assembled, six locking portions β positioned in the left-right direction are formed side by side in the front-rear direction at regular intervals on the inner bottom of the container body 20. become.

  The side panel 22 and the side inner panel 23 on both sides are formed with semicircular cutouts 22a and 23a facing each other at the front side thereof, and these cutouts 22a and 23a are formed on the side panel 22 and the side inner side. When the panel 23 is folded and overlapped, a semicircular cutout portion C that makes it easy to take out the granular contents is formed. In addition, folding flaps 25 are provided on the front and rear sides of each side panel 22, respectively.

  A front panel 26 is connected to the front portion of the bottom panel 21 via a fold line, a front inner panel 27 is connected to the front panel 26 via a fold line, and a fold line is connected to the rear portion of the bottom panel 21. A rear panel 28 is connected to the rear panel 28, and a rear inner panel 29 is connected to the rear panel 28 via a broken line. The front panel 26 is formed with protruding pieces 26a on both sides so as to bite into both folded flaps 25, and the rear panel 28 is projected only on one side so as to bite into one folded flap 25. A piece 28a is formed.

  FIG. 4 is a development view of a blank for assembling the rectangular parallelepiped member 30. This blank is obtained by punching a paperboard into the shape shown in the figure. A front plate 32 is connected to the front of the top plate 31 via a broken line, and a rear plate 33, a bottom plate 34, and an adhesive margin piece 35 are connected to the rear of the blank via a broken line. The side plates 36 are connected in series in this order, and the side plates 36 are connected to the left and right via a broken line. A locking piece 37 is continuously provided in front of the front plate 32 via a fold line provided slightly inside from the end edge.

  Further, in order to form a protruding locking piece 33a at the rear of the upper surface of the rectangular parallelepiped member 30, a notch is formed in the middle so as to bite into the top plate 31 side at the boundary between the rear plate 33 and the top plate 31. In order to form the leg piece 33b behind the lower surface of the member 30, notches are formed on both sides so as to bite into the adjacent bottom plate.

  In order to create a sliding carton, as shown in FIG. 5, the assembled rectangular parallelepiped member 30 and seven granular contents A are stored in the assembled container body 20, and the container body 20 in the stored state is enclosed. Then, the sleeve 10 is assembled.

  The procedure for assembling the blank of FIG. 3 to create the container body 20 is as follows. First, the side panel 22 and the side inner panel 23 are folded and bonded together, and the bottom inner panel 24 is bonded to the bottom panel 21. Thus, as shown in FIG. 1, a semicircular cutout portion C is formed at the upper front end of the double wall where the side panel 22 and the side inner panel 23 overlap, and a semicircular cutout portion C is formed on the inner bottom. Six locking portions β arranged at regular intervals are formed by the notches 24a.

  Next, the front and rear are assembled into a tray shape. That is, the flap 25 is folded in front, and then the front panel 26 and the front inner panel 27 are folded and bonded together. Thereby, it will be in the state where the protrusion piece 26a protruded to both the front side edge parts of the container main body 20. FIG. At the rear, the flap 25 is folded, and then the rear panel 28 and the rear inner panel 29 are folded and bonded together. Thereby, it will be in the state where the protrusion piece 28a protruded to one side of the rear side edge part of the container main body 20.

  In order to assemble the rectangular parallelepiped member 30 from the blank of FIG. 4, the glue piece 35 is bonded to the inner surface of the front plate 32, and then the rectangular plate is raised by the top plate 31, the front plate 32, the rear plate 33 and the bottom plate 34. The side plate 36 is bent inward and the locking piece 37 is bent in the direction along the bottom plate 34. As a result, as shown in FIG. 1, the protruding locking piece 33 a protrudes from the upper surface rear side of the rectangular parallelepiped member 30, and the leg pieces 33 b protrude from both sides of the lower rear surface.

  And after accommodating the rectangular parallelepiped member 30 and the seven granular contents A in the container main body 20, the container main body 20 is mounted on the blank which forms the sleeve 10, First, the side panel 14 and the top | upper surface inner panel 15 are mounted. Is folded so as to cover the container body 20, and then the side panel 12 and the top panel 11 are folded and the top panel 11 is laminated on the top inner panel 15, and the sleeve 10 is assembled. A sliding carton is created. When the sleeve 10 is assembled in this way, seven locking portions α arranged at regular intervals are formed on the ceiling of the sleeve 10.

  Further, a notch portion 14b having a length corresponding to one stroke is formed behind the side panel 14 in the sleeve 10, and the protruding piece 28a of the rear panel 28 in the container body 20 is movable in the notch portion 14b. Become. The semicircular cutout portion C formed on the front side portion of the container body 20 is exposed when the container body 20 is pulled out by one stroke with respect to the sleeve.

  When taking out the granular content A from the sleeve type carton, the container body 20 is pulled out from the sleeve 10 as shown in FIG. At this time, when the projecting pieces 26a at both the front end portions of the container body 20 are gripped and slid by hand, the projecting pieces 28a at one end of the rear end portion of the container body 20 become the notched portions 14b of the sleeve 10. It can be pulled out for one stroke until it comes into contact. Since the arc-shaped cutouts 12a and 14a are formed at the front ends of the side panels 12 and 14 in the sleeve 10, the front end of the container body 20 can be easily grasped and pulled out by hand.

  When the first one content A is taken out, the rectangular parallelepiped member 30 is positioned at the rearmost side of the container body 20, but from the next content A, the rectangular parallelepiped member 30 has its locking piece 37 bent. The state is engaged with the locking portion β on the bottom of the container body by the repulsive force to return to the original state. In any case, the protruding locking piece 33a on the upper surface of the rectangular parallelepiped member is engaged with the locking portion α on the sleeve ceiling. It does n’t match. When the container body 20 is pulled out of the sleeve 10 from this stored state, the rectangular parallelepiped member 30 remains at the end of the container body 20 at the first time, and from the next, the locking piece 37 on the bottom surface of the rectangular parallelepiped member is in the container body. The container body 20 moves forward by one stroke together with the rectangular parallelepiped member 30 and the granular contents A while engaging with the bottom locking portion β, and the protruding locking piece 33a on the upper surface of the rectangular parallelepiped member is immediately in front of the sleeve ceiling. It operates so as to engage with the locking portion α.

  In taking out the granular contents A, the semi-circular cutout portion C is provided at the front side end of the container main body 20 so that the take-out operation is facilitated. And after taking out one granular content A, as shown in FIG. 7, the container main body 20 is pushed in with respect to the sleeve 10 from the open state. At this time, if the front panel 26 of the container body 20 is pushed and slid by hand, it can be pushed in for one stroke until the projecting pieces 26a on both front ends of the container body 20 abut against the sleeve 10.

  When the container main body 20 is pushed into the sleeve 10, the rectangular parallelepiped member 30 and the remaining granular content A of the container main body 20 remain while the protruding locking pieces 33 a on the upper surface of the rectangular parallelepiped member are engaged with the locking portions α of the sleeve ceiling. It moves forward by one stroke and operates so that the locking piece 37 on the lower surface of the rectangular parallelepiped member engages with the locking portion β in front of the bottom of the container body.

  As described above, by performing the opening / removing / closing operations, the granular contents A are pushed out one by one to the take-out position, so that the granular contents can be reliably taken out one by one until the end. Of course, it is also possible to close it without removing it after opening. And even after taking out some of the granular contents A, the granular contents A will not fall inside and be damaged.

  As mentioned above, although the form for implementing this invention has been demonstrated in detail, the slide-type carton by this invention is not limited to said embodiment at all, and various in the range which does not deviate from the meaning of this invention. Of course, changes are possible. For example, although the bent locking piece is used in this embodiment as the locking piece on the lower surface of the rectangular parallelepiped member, it can be formed by pasting another piece of paper.
