Description

  The present invention relates to a paper packaging container in which a tray for storing confectionery such as chocolate and candy is provided in a cylindrical sleeve so that it can be inserted and removed in the longitudinal direction along the cylindrical axis of the sleeve.

  Conventionally, it is composed of a box-shaped tray with an open top and a rectangular tube sleeve with one end closed, and the tray containing confectionery is moved back and forth so that it can be taken in and out of the sleeve in the cylinder axis direction. Paper packaging containers have been proposed.

  In this type of packaging container, after opening the package, the tray is pulled out from the sleeve, and the confectionery placed in the tray can be taken out (see Patent Document 1).

JP 2006-1613 A

  The above packaging container is designed so that the tray can be simply taken in and out of the sleeve so that the confectionery can be taken out, so that the tray is monotonous and uninteresting, and when the tray is pushed all the way into the sleeve, it is reliable. It was difficult to see if the tray was completely stored in the sleeve.

  Accordingly, an object of the present invention is to give pleasure to the purchaser and to make it clear that the tray is securely stored in the sleeve.

  In order to solve the above-described problems, the present invention provides a snap piece on the outer peripheral surface of the tray that can be raised and lowered, and the snap piece is urged in the standing direction and falls stepwise toward the inner peripheral surface of the sleeve. Is provided, and the tip of the snap piece falls into the stepped portion by the urging force in a state where the snap piece of the tray is directed rearward, and the snap piece is It was designed to be stored in the recess.

  In this way, when the tray is completely accommodated in the sleeve, the snap piece of the rearward-facing state has its leading edge dropped into the stepped portion due to its urging force, and collides with the inner peripheral surface of the sleeve to make a sound. The snap piece is stored in the recess of the sleeve. For this reason, it can be seen that the tray is completely stored by the sound and vibration when the tip edge of the snap piece falls into the stepped part or collides with the inner peripheral surface. You can experience the fun of taking in and out.

  As a configuration of the present invention, a paper packaging is provided in which a tray is accommodated in a cylindrical sleeve so as to be movable in the front-rear direction along the cylinder axis direction of the sleeve, and the tray can be taken in and out by the movement. In the container for use, a snap piece that can be raised and lowered in the moving direction is provided on the outer periphery of the tray, and the snap piece is biased in a standing direction, and a recess is provided on the inner periphery of the sleeve. The rear edge is a stepped part that falls forward, and the tray is inserted forward into the sleeve, so that the snap piece is directed rearward by the biasing force in the state of the inner periphery of the sleeve. And sliding the surface, the tip edge of the snap piece falls into the stepped portion, the snap piece is stored in the recess, the snap piece is stored in the recess, By drawing towards the laser to the rear, and the snap piece is inverted forward in the recess, it can be adopted to leave from the recess in its inverted state.

  In the above configuration, if the snap piece is used to reverse the front by pulling the tray backward while the snap piece is locked to the peripheral edge of the concave, It is possible to prevent the snap piece locked to the periphery of the plate from being damaged.

  By pulling out the tray toward the rear, the snap piece is reversed to the front, and a locking step portion is formed on the rear side of the recess in the sleeve so that the front side becomes higher, and the snap piece is directed forward. In this state, by inserting the tray forward into the sleeve, the snap piece is locked to the locking step portion, and the tray is further inserted forward in the locked state, so that the snap piece Can be used that reverses backward.

  If it does in this way, after pulling out a tray back, when the tray is inserted toward the front in the sleeve, the snap piece can be reversed backward.

  Further, the sleeve has a quadrangular cross section, the tray has left and right side plates and front and rear end plates rising from a peripheral edge of the rectangular bottom plate, and the snap piece is a ridge line with the front end plate on the bottom plate of the tray It is possible to employ a cut-and-raised piece that can be raised and lowered with the center of rotation as the center of rotation. If it does in this way, if the said front end plate is bent, a snap piece will stand up, Therefore It is not necessary to change the assembly process of a tray from the conventional one.

  A face plate for closing the front end surface of the sleeve is provided, and a tongue piece having an engagement hole is provided continuously at an end edge of the face plate. The tongue piece is overlapped and locked on the inner peripheral surface of the sleeve, and the engagement is achieved. While forming the said recessed part with the peripheral surface of a hole and the surrounding surface of a sleeve, what forms the said latching step part with the front-end | tip edge of the said tongue piece is employable.

  By doing this, by inserting the tray forward into the sleeve, the snap piece is locked to the locking step formed by the tip edge of the tongue piece, and by further inserting the tray in its locked state, The snap piece flips backward.

  In addition, an arc-shaped notch is formed at the tip edge of the tongue piece, the tip of the snap piece is formed linearly along the width direction of the tray, and both widthwise edges of the tip of the snap piece are If it is to be locked to the peripheral edge of the notch, by inserting the tray forward into the sleeve, the both side edges of the snap piece are moved along the notch edge of the tongue piece from both axial sides toward the center. Since it is pressed, the snap piece is easily reversed backward.

  Both side edges in the width direction of the engagement holes of the tongue pieces are tapered so as to approach each other toward the front, and by pulling out the tray toward the rear, both side edges of the snap pieces are in the engagement holes. What engages with a both-sides edge can be employ | adopted.

  In this way, by pulling the tray housed in the sleeve rearward, both side edges of the snap piece of the tray engage with both side edges of the engagement hole. If the tray is further pulled out in this engaged state, the snap piece rotates forward about the line connecting the engaging portions on both sides of the both side edges of the snap piece and the both side edges of the engagement hole. Easy to reverse.

  Since the snap piece can be elastically deformed so that the root portion of the snap piece is upward if it has a notch extending rearward from the both side edges of the width direction to the bottom plate of the tray, the snap piece When reversing, the root part escapes upward and smooth reversal is possible.

  As described above, according to the present invention, since the sound is produced when the tray is completely stored in the sleeve, it can be seen that the tray is securely stored in the sleeve. In addition, the sound makes it possible for the purchaser to experience the enjoyment of putting in and out of the sound and adding value.

Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.
In the paper packaging container 10 according to the embodiment of the present invention, the blanks of the members shown in FIGS. 1A and 3A are respectively assembled to the sleeve 11 and the tray 30 as shown in FIGS. A box-shaped sleeve 11 made of paperboard and having an open end, and a tray 30 movable in the sleeve 11 along the cylinder axis direction. The tray 30 is moved by movement in the cylinder axis direction. The sleeve 11 can be taken in and out.

  As shown in FIG. 1A, the blank of the sleeve 11 has side plates 13 connected to both side edges of the top plate 12, a bottom plate 14 on the outer edge of one side plate 13, and the bottom plate 14. A glue plate 15 is continuously provided on the outer edge of the plate. The end plate 16 is connected to one end edge of the upper surface plate 12, and the tongue piece 17 is connected to the end edge of the end plate 16 via a crease line.

  The tongue piece 17 is cut out in a trapezoidal shape from an end edge (ridge line) with the end plate 16 to form an engagement hole 21. The engaging hole 21 has a tapered shape in which both side edges (both side edges in the width direction of the sleeve 11) serving as both oblique sides approach each other toward the end plate 16.

  When the sleeve 11 is assembled, the tongue piece 17 is overlapped and locked on the bottom plate 14 which is the inner peripheral surface of the sleeve 11. By locking the tongue piece 17, the end plate 16 is also locked, and the front end surface of the sleeve 11 is closed. In addition, this latching can employ | adopt the thing latched to a notch | incision, the thing by adhesion | attachment, etc. Thereby, a recess 23 is formed by the peripheral edge of the engaging hole 21 of the tongue piece 17 and the bottom plate 14.

  Since the recess 23 is formed by overlapping the tongue piece 17 on the inner peripheral surface (bottom plate 14) of the sleeve 11, the rear edge of the recess 23 is the front side by the thickness of the tongue piece 17. It becomes the step part 25 which falls toward. Further, the front edge of the tongue piece 17 and the inner peripheral surface of the sleeve 11 form an engaging step portion 24 that increases toward the front.

  When the tray 30 is inserted forward into the sleeve 11, the snap piece 39 in the forward direction is locked to the engagement step portion 24, and the tray 30 is further inserted forward in the locked state. Thus, the snap piece 39 is reversed backward (see FIG. 6).

  Since both side edges of the engagement hole 21 are tapered, when the tray 30 is pulled out rearward, both side edges of a snap piece 39 described later engage with both side edges on the rear side of the engagement hole 21. . When the tray 30 is further pulled out, the snap piece 39 rotates around the line connecting the engaging portions on both sides of the both side edges of the snap piece 39 and the both side edges of the engaging hole 21, so that the snap piece 39 is inverted. It is easy to open (see FIG. 7D).

  Folding pieces 18 are connected to one end edge of the both side plate surfaces 13, the overlapping plate 19 is connected to one end edge of the bottom plate 14, and the folded piece 20 is connected to the other end. The folded piece 20 engages with the leading edge of the folded plate 35 inserted into the notch 37 of the bottom plate 31 of the tray 30 by pulling the tray 30 rearward, and prevents the tray 30 from falling off.

  To assemble the sleeve 11 from the blank shown in FIG. 1 (a), as shown in FIG. 1, the side plates 13 and the end plate 16 are erected with respect to the upper surface plate 12, and the tongue piece 17 and the folded piece 20 are folded inward. . Further, the glue plate 15 is laminated and pasted on the side plate 13, and the overlapping plate 19 of the bottom plate 14 is stuck on the end plate 16. Thereby, as shown in FIGS. 2A and 2B, the sleeve 11 is formed.

  As shown in FIG. 3A, the blank of the tray 30 is provided with side plates 32 connected to both side edges of the bottom plate 31, and inner end plates 33 and outer end plates 34 at both end edges of the bottom plate 31. In order, the folded plate 35 is connected to the outer end edges of the outer end plates 34. The side plate 32 has a configuration in which folding pieces 36 are provided on both side edges.

  A U-shaped notch 37 is provided near one inner end plate 33 of the bottom plate 31, and the notch 37 has a central portion recessed in a V shape, and both side portions thereof have an inner end plate 33. It extends toward. When the tray 30 is assembled, as shown in FIG. 4, the front end plate 42 is formed by inserting the edge of the folded plate 35 into the V-shaped portion.

  Further, the one inner end plate 33 is cut into a U-shape from an end edge (ridge line) with the bottom surface plate 31 and further cut into the bottom plate 31 intersecting with the end edge (ridge line). A piece 39 is provided. When the tray 31 is assembled, the snap piece 39 becomes a cut-and-raised piece that is provided on the bottom plate 31 of the tray 30 so as to be undulated around the ridge line with the front plate 42, and when bent toward the bottom plate 31, The bottom plate 31 is biased in the standing direction. Further, since the snap piece 39 stands when the front end plate 42 is bent, it is not necessary to change the assembly process from the conventional one.

  The tip of the snap piece 39 is formed linearly along the width direction of the tray 30. If the tip of the snap piece 39 is linear, both sides in the width direction of the tip of the snap piece 39 are engaged with the peripheral edge of the notch 22 of the tongue piece 17. When the tray 30 is inserted forward into the sleeve 11 in this locked state, both sides of the snap piece 39 are pressed toward the center along the edge of the notch 22, and the snap piece 39 is inverted backward.

  Since the snap piece 39 has notches extending forward from the both sides to the bottom plate 31, when the tray 11 is assembled, the root portion is directed upward as shown by the arrow in the figure. If elastic deformation is possible and the base portion of the snap piece 39 is elastically deformed, the urging force is increased (see FIG. 6B). In addition, the urging force is increased, and when the snap piece 39 is reversed, the root portion thereof escapes upward to enable smooth reversal. Note that deformation of the bottom plate 31 of the sleeve 30 can also be expected during the reversal.

  A cut 38 is also provided near the other inner end plate 33. The notch 38 is provided in the width direction of the tray 30, and a central portion thereof is recessed in a V shape toward the other inner end plate 33. When the tray 30 is assembled, the notch 38 is folded back to the V shape portion. A rear end plate 41 to be described later is formed by inserting the edge of the plate 35 (see FIG. 4).

  The outer end plate 34 on the one inner end plate 33 side is cut into a U shape from the end edge (ridge line) with the folded plate 35 and further reaches the folded plate 35 crossing the end edge (ridge line). And has a cutout hole 40 cut out with the end edge (ridgeline) interposed therebetween.

  By cutting the cutout hole 40 up to the folded plate 35, the portion between the cuts of the folded plate 35 can be deformed upward. Due to the deformation, the tray 30 is inserted into the sleeve 11 toward the front, and when the snap piece 39 is in sliding contact with the tongue piece 17, as shown in FIG. Thus, the snap piece 39 is easily elastically deformed.

  On the other hand, in order to assemble the tray 30, as shown in FIG. 3B, the side plates 32 and the inner end plates 33 are raised with respect to the bottom plate 31, and the folding pieces 36 of the side plates 32 are folded inward. . Further, both outer end plates 34 are folded inward, the folded plate 35 is valley-folded, and the end edges thereof are inserted into the cuts 37 and 38. By assembling in this way, as shown in FIG. 4, the tray 30 is formed, the left and right side plates 32 are formed on both side edges of the bottom plate 31, and the front and rear end plates 42 and 41 are formed on the front and rear end edges.

  The sleeve 11 and the tray 30 shown in FIG. 5 assembled as described above are first inserted forward into the sleeve 11 from the front end plate 42 side. As for the inserted tray 30, the snap piece 39 engages with the notch 22 used as the engagement step part 24 at the front-end edge of the tongue piece 17 (refer Fig.6 (a)). When further pushed in, as shown in FIG. 7A, the notches 22 of the tongue piece 17 are provided in an arc shape, so that both side edges of the snap piece 39 follow the edges of the notch 22 from both sides in the width direction toward the center. The snap piece 39 is reversed backward. As the snap piece 39 is inverted, the snap piece 39 exerts a biasing force in the standing direction.

  When the tray 30 is pushed further forward, as shown in FIG. 6B, the snap piece 39 rides on the tongue piece 17 of the sleeve 11 in a state of facing backward, and the tongue piece 17 is applied by the urging force. Slide. At this time, it will be in the state elastically deformed so that the base part of the snap piece 39 may become upward (refer FIG.7 (b)).

  Next, when the tray 30 is further pushed forward and the tray 30 is completely stored in the sleeve 11 as shown in FIG. 6C, the snap piece 39 is formed in the recess 23 by the engagement hole 21. It falls into the step 25 at the rear edge and is stored in the recess 23. At this time, since the snap piece 39 is urged in the standing direction, the leading edge of the snap piece 39 collides with the bottom plate 14 through the recess 23 to generate sound (see FIG. 7C).

  If a sound is generated when the tray 30 is stored, it can be seen that the tray 30 is securely stored in the sleeve 11. Furthermore, the purchaser can experience the joy and the added value of the product is improved.

  When the tray 30 in the state of being accommodated in the sleeve 11 is pulled out, as shown in FIG. 6 (d), the snap pieces 39 of the tray 30 are arranged on both side edges of the engagement hole 21 (the width of the sleeve 11). It engages with the rear edge of both sides of the direction (see FIG. 7D). When the tray 30 is further pulled out rearward in this engaged state, as shown in FIG. 6 (e), the snap piece 39 is reversed to the front and detached from the recess 23 in the reversed state, so that the inside of the sleeve 11.
