Description

  The present invention relates to a so-called pop-up type packaging box in which articles in the packaging box are pushed out from below and pop up as the lid is opened.

  Conventionally, as an extrusion box from which goods are pushed out from the bottom as the lid is opened, a raised floor is provided via an inner back plate extended via a step hinge portion inside the lid opened and closed with the main hinge portion as a fulcrum. An extension is disclosed (see Patent Document 1). In this extrusion box, at the same time as the lid is opened, the back edge of the raised floor is lifted, and the product placed on the raised floor is extruded.

  In addition, conventionally, in a storage box supported by one end of the lid on the end of the box main body and opened and closed vertically, a bottom plate extending to the inner side of the box main body and having a folded piece at the tip end is extended to the support side of the lid What was installed or attached is disclosed (see Patent Document 2). Also in this storage case, the extending or attaching side of the bottom plate is lifted in response to the opening and closing of the lid.

JP 2000-203559 A Japanese Utility Model Publication No. 61-172012

  However, due to the structure that the raised floor or the bottom plate lifts up with the cover plate, the push-out box or the storage box has the folded pieces at the tip of the raised floor or the lower side of the bottom plate upward when the contents are taken out. By shifting, a part of the inner surface of the box is exposed in the housing space. For this reason, in the so-called pop-up state when the lid was opened, it could not be said that it was excellent in the appearance at the time of taking out of the contents.

  Although it is conceivable to cover the tip of the raised floor or bottom plate with a cover member or the like in order to prevent the inner surface of the box from being exposed, the structure of the members may be complicated or the number of parts may be increased so as not to restrict the lifting operation. You will need to These may cause the assembly to be complicated, the structure to be complicated, or the weight to be increased.

  The present invention has been made in view of such circumstances, and in the pop-up type packaging box in which the contents are pushed out in response to the opening operation of the lid, the contents of the contents in the pop-up state can be maintained with a relatively small number of parts. An object is to provide a product which is excellent in appearance at the time of taking out.

  In order to solve the above-mentioned subject, the pop-up type packing box of the present invention takes measures of the following [1]-[5]. However, numeral strings or character strings of numerals and alphabets described subsequently to the component names in the following and each embodiment are reference numerals for referring to parts in the embodiment in the drawings, and each drawing and each reference It is not the meaning limited to the structure specified to description.

[1] The pop-up packaging box of the present invention is
A box main body 1 having a storage space 10 opened at the upper part in the upper surface frame 11 and capable of storing the storage object O in the storage space 10 with the upper surface open;
An openable cover plate 2 connected to one side of the upper surface frame 11 of the box main body 1 to cover the upper surface of the box main body 1 (the upper surface frame and the opening of the accommodation space);
The base end is fixed to the back surface of the lid plate 2 and bent or bent into the housing space and housed in the housing space 10, and the tip end is lifted as one free end into one side in the housing space Piece 3 and
In the storage space 10, it is stacked and disposed on the upper surface side of the lifting piece 3 to cover the back surface of the storage O stored in the storage space and to buffer the contact of the storage O to the side surface of the box body 1 And a buffer plate 4, and
When the cover plate 2 is opened, along with the opening operation of the cover plate 2, the lifting piece 3 is pulled upward in an inclined state to push up the stored material O obliquely from the back side, and the proximal end of the lifting piece of the stored material O In the pop-up state (b), part of the
Further, when the pop-up stored object O is taken out from the storage space 10, a part of the buffer plate 4 (for example, the cover piece 41 of the embodiment described later) is on the upper surface side of the lifting piece 3 in the storage space 10. , Characterized in that it is exposed in the housing space 10 in a state of being pushed up obliquely.

  According to this configuration, when the container O in the pop-up state is taken out from the storage space 10, the “buffer plate 4” (for example, the cover of the embodiment described later) The piece 41) is exposed in the accommodation space 10. Since most parts including the lower side of the lifting piece 3 are pre-covered by the buffer plate 4, the contents are taken out without exposing a part of the internal structure of the box as the lifting piece 3 rises. It will be excellent for the appearance of time.

  Moreover, the buffer plate 4 plays the role of a protective buffer material of the content O so that the contained content O accommodated therein contacts the side of the box body 1 and receives no impact. The cushioning plate 4 not only functions as a cover material to adjust the appearance at the time of taking out but also functions as such a protective cushioning material, thereby a packaging box which achieves both storage protection and appearance with a relatively small number of parts. Form.

[2] Also, in the above pop-up packaging box,
The buffer plate 4 is provided with a cover piece 41 for covering an upper half of the opening shape of the accommodation space 10 and a plurality of folds or bends which extend from at least one side of the cover piece 41 and run parallel to the one side Or with a buffer piece 42 folded in the valley,
The buffer piece 42 is disposed in the upper surface frame on the outer periphery than the opening shape in plan view in the closed storage state (a),
One surface of the mountain-folded surface or the valley-folded surface constituting the buffer piece 42 is in contact with the lower side surface (front side surface) of the container O in the pop-up state to push up the one side of the container O diagonally Is preferred.

  In such a case, in the pop-up state, the cover piece 41 of the buffer plate 4 pushes up the back surface of the contents O diagonally and the one side of the buffer piece pushes up the lower side of the contents O diagonally. Become.

  Further, in the closed storage condition (a), the buffer plate 4 covers the back surface of the storage item O and protects the bottom portion of the storage space with the lifting piece 3 in a double protection manner. In this case, the double buffer plate 4 and the lifting piece 3 cooperate to push up the contents obliquely. As a result, the lifting piece 3 can be lifted with a stable push-out force without bending or causing setback due to repeated operations.

[3] Also, in any of the above pop-up packaging boxes,
Lifting piece 3 is
A first lifting piece 31 on the proximal end side fixed to the back surface of the lid plate 2 and having a longitudinal length greater than the depth of the housing space 10;
And a second lifting piece 32 on the tip end side formed continuously with the tip side of the first lifting piece 31 as a bending side on the tip side of the tip side,
Further, on the upper surface of the second lifting piece 32, a single-sided decoration 32I consisting of at least one of a character and a pattern is provided.
In the storage state (a) in which the storage item O is stored, the second lifting piece 32 is superimposed on the lower surface of the covering piece 41,
The single-sided decoration 32I of the second lifting piece 32 is exposed from the end of the covering piece 41 in the pop-up state (b).
By varying the opening angle of the lid plate 2, it is preferable to vary the amount of exposure of the single-sided decoration of the second lifting piece superimposed on the lower surface of the covering piece.

According to the above configuration, when the stored item O is taken out in the pop-up state (b), the second lifting piece 32 is exposed from the end of the covering piece 41 with a predetermined exposure amount. For example, when the opening angle of the cover plate is gradually increased, the second lifting piece 32 having the single-sided decoration 32I is gradually exposed from the end of the covering piece 41, and the exposure amount of the single-sided decoration 32I is the lid It is also possible to make a variable display of the single-sided decoration 32I variable according to the opening angle of the plate 2.

Furthermore, in the configuration of the above [3], the cover piece 41 of the buffer plate 4 is configured to have a larger area than the second lifting piece 32,
The second lifting piece 32 and the covering piece 41 have single-sided decorations 32I and 41I made of at least one of characters and patterns on one side of each of the second lifting piece 32 and the covering piece 41.
While the cover piece 41 of the buffer plate 4 covers all the upper surfaces of the second lifting pieces 32 in the accommodation state (a) in which the contents are accommodated,
As the opening angle of the cover plate 2 is varied in the pop-up state (b), the second lifting piece 32 superimposed on the lower surface of the covering piece 41 slides from one end of the covering piece 41 of the buffer plate 4 Preferably, the single-sided decoration 32I is exposed from the end of the cover piece 41, and the exposure amount of the single-sided decoration 32I is variable along with the variable amount of the opening angle of the lid plate 2 in the pop-up state (b).

According to the above configuration, the display of the single-sided decoration 41I and the display of the single-sided decoration 32I exposed with a predetermined exposure amount from the end of the single-sided decoration 41I are combined, and the appearance is excellent. For example, when the opening angle of the cover plate is gradually increased, the second lifting piece 32 having the single-sided decoration 32I is gradually exposed from the end of the covering piece 41 having the single-sided decoration 41I. It is also possible to display a combination decoration in which a combination pattern or combination characters formed by combining 41I and 32I change according to the opening angle of the cover plate 2.

[4] Also, in any of the above pop-up packaging boxes,
The buffer plate 4 is a cover piece 41 for covering an upper half of the opening shape of the accommodation space 10, and is bent and extended from at least one side of the cover piece 41, and is mountain-folded by a plurality of parallel bending or bending parts. Or valley-folded buffer pieces 42,

It is preferable that the protruding piece 43 restricts elastic compression equal to or less than the protruding length of the buffer piece in the closed storage state (a).

  According to the above configuration, the cover piece 41 of the buffer plate 4 pushes up the back surface of the stored item O obliquely, and one surface of the buffer piece pushes up the lower side surface of the stored item O obliquely.

[5] Further, in the pop-up type packaging box of the present invention,
When the side close to the base of the cover plate 2 of the box body 1 is the rear, and the side close to the cover tip of the cover 2 is the front,
The front frame 11F and the rear frame 11B that constitute the upper surface frame are provided on the front and rear sides of the box body 1, respectively.
Further, the buffer plate 4 is extended in the front direction by bending from one side of the front portion of the cover piece 41 covering the cover piece 41 for covering the full length in the front-rear direction of the opening shape of the accommodation space 10 in the front view. And a buffer piece 42 which exerts an elastic function in the forward direction,
When the lid is gradually opened from the accommodation state (a) in which the articles are accommodated, and the state is shifted to the pop-up state (b),
When the buffer piece 42 elastically biases the cover piece 41 rearward, the rear end of the cover piece 41 temporarily enters the first pop-up state (b1) with the rear frame 11B entering the rear side,
When the lifting angle of the lifting piece 3 becomes a predetermined size, from the first pop-up state (b1),
It is preferable that the cover piece 41 pushed up by the lifting piece 3 is in a second pop-up state (b2) in which the cover piece 41 protrudes to the front side of the rear frame 11B beyond the frame side of the rear frame 11B.

  The transition from the first pop-up state (b1) to the second pop-up state (b2) takes place instantaneously at a predetermined critical lift angle. This state transition means that one end of the cover piece 41 is bent and locked from the back surface of the rear frame 11B, the locking is released and the one end is released (for example, as described later) See Figure 3).

  In the first pop-up state (b1), the cover piece 41 held by the rear frame 11B and located on the lower surface of the rear frame 11B is pushed up by the lifting piece 3, thereby exceeding the frame end side of the rear frame 11B A transition to the pop-up state (b2) will be made instantaneously. At this time, by pushing up the back surface of the storage item O instantaneously to shift to the second pop-up state (b2), an operation occurs in which the storage object O momentarily receives a strong force and pops up. This pop-up action is an action excellent in dynamic visual effects because the contents O appear to jump slightly.

  According to the pop-up type packaging box of the present invention, in the pop-up type packaging box in which the contents are pushed out according to the opening operation of the lid, the appearance at the time of taking out the pop-up contents is excellent It became possible to provide things.

  The pop-up operation occurs when the flap 22 at the front of the cover plate 2 is pulled out of the insertion hole 12D from the accommodation state (a) in which the storage object O is accommodated and the cover plate 2 is opened (FIG. 2). With the opening operation of the lid plate 2, the first lifting piece 31 of the lifting piece 3 is drawn upward, and the second lifting piece 32 bent and continued to the end of the first lifting piece 31 is inclined on the back surface side of the stored item O Pulled out in the direction (Figure 2b). Thereby, the buffer plate 4 in contact with the upper surface of the second lifting piece 32 slides in the downward direction with respect to the second lifting piece 32 and faces the inclined direction, and the cover piece 41 of the buffer plate 4 pushes out the lower surface of the content O As a result, a pop-up state (b) occurs in which the rear part of the storage item O is lifted above the storage space (FIG. 2, FIG. 4). In this pop-up state, the front side of the storage item O is in surface contact with the second buffer piece 42B, and the storage item O is pushed diagonally upward by the elastic reaction force of the buffer piece 42 (see the arrow in FIG. 2B) .

The projecting piece 43 of the buffer plate 4 restricts elastic compression equal to or less than the above-mentioned projecting length of the buffer piece 42 by the tip end portion coming into contact with the inner surface of the front lower portion of the box body in the closed storage state (a). (FIG. 2 (b)). The pop-up state (b) is divided into two states of a first pop-up state (b1) and a second pop-up state (b2) (FIG. 3 (b1) (b2)). The state transition is made from the first pop-up state (b1) to the second pop-up state (b2) according to the increase of the opening angle (FIG. 3). Just before the transition from the first pop-up state (b1) to the second pop-up state (b2), the tip end of the projecting piece 43 is in contact with and locked to the inner surface of the front lower portion of the box body. At the moment of transition to the second pop-up state, the protruding piece 43 contacts the bottom plate 13 of the box main body 1 and pushes up the back surface of the storage item O (Fig. 2 (b), Fig. 3).
One surface of the mountain-folded surface 42 or the valley-folded surface 42 that constitutes the buffer plate 4 overlaps the upper surface of the lifting piece 3 and pushes up the front side, which is one side of the contents O, together with the lifting piece 3 (FIG. b), Figure 3).

(State transition from the first pop-up state (b1) to the second pop-up state (b2))
The state transition from the first pop-up state (b1) to the second pop-up state (b2) will be described in detail. First, when the cover plate 2 is gradually opened from the storage state (a) in which the storage object O is stored and the lid is closed, the buffer piece 42 elastically covers the cover piece 41 to the rear when transitioning to the pop-up state. As a result, the first pop-up state (b1) in which one end of the rear part of the cover piece 41 enters the back side than the rear frame 11B is temporarily set (FIG. 3 (b1)). At this time, the opening angle of the cover plate 2 is a critical lifting angle θ1 which does not exceed the predetermined opening angle θ2, and the frame end 11BE of the back frame 11B is engaged with the tip end near the center of the back surface of the first lifting piece 31. Then, the first lifting piece 31 is curved, and the broken line 3F of the lifting piece 3 is maintained in a state of being locked closer to the lower rear than the frame end 11BE of the rear frame 11B (FIG. 3 (b1)).

  The cover plate 2 is pushed up by the lifting piece 3 from the first pop-up state (b1) by setting the opening angle of the lid plate 2 to the opening angle θ2 exceeding the predetermined critical lifting angle θ1 with the lid opening. A state transition is instantaneously made to a second pop-up state (b2) in which 41 projects to the front side of the rear frame 11B beyond the frame side of the rear frame 11B (FIG. 3). In this state transition, the distal end locking state of the frame end 11BE of the rear frame 11B to the first lifting piece 31 and the locking state of the polygonal line 3F to the lower portion of the frame end 11BE of the rear frame 11B (FIG. b1) is released, which means that the broken line 3F of the lifting piece 3 shifts to the state (FIG. 3 (b2)) opened above the frame front end 1BE of the rear frame 11B. Due to this state transition, an elastic reaction force is generated on the cover piece 41, and the stored material O instantaneously receives a relatively large lifting force upward (see the arrow in FIG. 3 (b2)). In other words, the state transition to the second pop-up state (b2) of the present invention is not a simple push-up operation, but it is an operation of instantaneously splashing and popping up the contents O via the cover piece 41.

(Exposure of one side decoration 41I)
Further, when the pop-up storage object O is taken out from the storage space 10, the single-sided decoration 41 I is on the upper surface side of the lifting piece 3 in the storage space 10 on the upper surface of the cover piece 41 which is a part of the buffer plate 4, It is exposed in a state where it is pushed up obliquely (FIG. 4 (b)).

(Variable combination decoration)
As the opening angle of the cover plate 2 is gradually varied in the pop-up state, the second lifting piece 32 superimposed on the lower surface of the covering piece 41 slides from one end of the covering piece 41 of the buffer plate 4 The single-sided decoration 32I is gradually and widely exposed. As a result, the pattern of the combination decoration is variable (FIG. 4).

  According to the configuration of the above embodiment, since the lifting piece 3 for lifting the stored item with the opening operation of the cover plate 2 is superimposed on the lower surface of the covering piece 41 covering the entire bottom of the housing space 10, the stored item is taken out When the lower end of the lifting piece 3 is not exposed or popped out, the appearance after taking out can be maintained. Furthermore, as a component for covering the lower part of the lifting piece 3, the covering piece 41 which is a part of the shock absorbing plate 4 which fulfills the buffer function of the contents is used. I will push it out. For this reason, the contents are not subjected to an excessive impact due to the pop-up operation, and the number of parts is not unnecessarily increased, and the safe and reliable lifting operation is performed with a relatively simple structure.

  As mentioned above, although the present invention was explained based on the form of each example, the form of these examples is illustration and various shape change is carried out to the above-mentioned each embodiment, unless it deviates from the main point of the present invention. Relocation, increase / decrease of components, addition of each component, deletion of partial configuration may be performed. For example, the second lifting piece 32 of the lifting piece 3 according to the embodiment is formed of a rectangular plate having a width smaller than the covering piece 41 and a half length of the covering piece 41. The bottom cushioning property may be increased to the same extent as 41, or it may be a multi-stage bending piece connected by a large number of bending parts along one length. Also, for example, in the buffer piece 4 of the embodiment, the first buffer piece 41A and the second buffer piece 41B are bent and continued in a chevron shape in a side view, but as another form, mountain folds and valley folds alternate in multiple stages. It may be one having a continuous piece in the form of a bellows, or one having a curved piece on the tip side of the mountain-folded portion. Moreover, as a form other than the said Example, what changed the shape of the accommodation space 10, and the arrangement | positioning at the time of accommodation of a thing may be used.

  In addition, those in which the number of cover plates is added or divided, for example, a structure that opens in a double door style, one in which the cover plate itself is bent, or one in which the opening direction of the lid is changed may be used. In addition, it is understood by those skilled in the art that modified examples in which each component or at least a part thereof is extracted and changed, increased, decreased, or combined are within the scope of the present invention.
