  This invention is made in view of such a subject, Comprising: The objective is to provide the technique regarding the hinge lid type | mold box which can open a hinge lid with one hand.

  In order to solve the above-described problems, the hinge lid type box according to the present invention employs the following means. That is, the present invention includes an outer box that has an open end and can accommodate articles therein, a hinge lid that is hinged to the rear edge of the open end and can open and close the open end, and a front wall of the outer box. A front frame provided along the side wall of the outer box and a side frame provided along the side wall of the outer box, the upper end side of the front frame and the side frame protruding from the open end. An inner frame that is provided on the box and guides opening and closing of the hinge lid, and the inner frame is formed at an exposed portion of an edge that forms a boundary between the front frame and the side frame, and corresponds to the outer box From the edge of the front box, which forms the boundary between the side wall and the front wall, to the inner side in the width direction of the outer box It has an inclined edge extending obliquely upward obliquely, a hinged lid type box.

  In the hinge lid type box according to the present invention, the inclined edge portion of the inner frame is inclined inward in the width direction of the outer box and extends obliquely upward. According to this, when a handle, for example, a consumer who has purchased a hinge-lid box, opens the hinge lid in a closed state, a twisting operation of twisting the outer box with one hand is performed. Then, along with the torsional deformation of the outer box, the inclined edge portion of the inner frame rises in the direction outside the plane of the front wall of the outer box, and the posture of the inclined edge portion tilts toward the front of the outer box.

  By tilting the tilted edge in the inner frame, the tip of the tilted edge abuts on the inner edge of the hinge lid and tilts toward the front of the outer box while pushing up the hinge lid. The hinge lid will be opened. That is, according to the hinge lid type box of the present invention, the operator can easily open the hinge lid by performing a twisting operation of twisting the outer box with one hand.

  Further, in the hinge lid type box, the side wall of the outer box along which the side frame continuous to the front frame via the inclined edge portion is inclined rearwardly outward in the width direction of the outer box from the front wall. The front wall and the rear wall may be connected as an inclined side wall that extends.

  In this way, by setting the side wall of the outer box corresponding to the inclined edge of the inner frame as the inclined side wall, the operator twists the outer box, so that the posture of the inclined edge of the inner frame is changed to the outer frame. It becomes easy to change to the posture which inclines toward the front of the box. Further, since the outer box has a shape that allows the outer box to be easily twisted, the amount of twisting can be easily ensured. Therefore, it is possible to increase the tilting degree when the tilted edge of the inner frame tilts forward of the outer box, and it becomes easier to open the hinge lid.

  Further, in the hinge lid type box, a cross sectional shape of the hinge lid and the outer box may be a parallelogram. According to this, when the handling person twists the outer box, it becomes easier to secure the amount of twist. As a result, it is possible to increase the degree of inclination of the inclined edge portion related to the inner frame, and it is possible to easily open the hinge lid with one hand.

  Further, in the hinge lid type box, a slit is formed at an end portion of the hinge connection portion where the outer box and the hinge lid are hinge-connected, at least at an end portion where the inclined edge portion is provided in front. It is good to be. Thereby, at the time of twisting of the outer box, the portion provided with the slit is more easily deformed. As a result, the tilting degree of the inclined edge portion related to the inner frame can be increased, and the hinge lid can be easily opened.

  Further, in the inner frame, an upper end portion of the side frame connected to the front frame via the inclined edge portion may be extended upward to a position higher than an upper end of the inclined edge portion. According to this, even after the contact state of the inclined edge portion with the inner surface of the hinge lid is released, the upper end portion of the side frame is held in contact with the inner side wall of the hinge lid. Then, when the upper end portion of the side frame that has been elastically deformed by the twisting operation is released, a driving force for opening the hinge lid is obtained by flipping and flipping up the side wall of the hinge lid. Therefore, it becomes easier to open the hinge lid.

  In addition, although the to-be-contained object accommodated in a hinge lid type | mold box is not specifically limited, For example, a tobacco product can be illustrated suitably as a to-be-contained object. Examples of tobacco products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), electronic cigarettes, chewing tobacco, snuff tobacco, and the like. In addition, the hinge lid type box may be a box type package for accommodating, for example, confectionery, gum or the like.

  Further, means for solving the problems in the present invention can be employed in combination as much as possible.

  The hinge lid type box 1 configured as described above is a package whose horizontal cross section has a parallelogram. When the consumer who has purchased the hinge lid type box 1 takes out the cigarette C, the hinge lid 3 can be opened by twisting the outer box 2 with one hand. Hereinafter, structural features related to the opening operation for opening the hinge-lid box 1 with one hand will be described.

  7 and 8 are views showing each state of the hinge lid type box 1 when the hinge lid 3 is opened. FIG. 7 is a perspective view of the hinge lid type box 1 in each state. FIG. 8 shows a front view and a right side view of the hinge lid type box 1 in each state.

  (A) has shown the state before opening operation of the hinge lid 3, In this state, the hinge lid 3 is closed completely. The consumer twists the outer box 2 while holding the hinge-lid box 1 in his hand. More specifically, an index finger, a middle finger, a ring finger or the like is hooked on the right rear box edge portion 28 of the outer box 2, and the right rear box edge portion 28 is pushed inward in the width direction of the outer box 2. At the same time, the thumb or the crotch portion of the thumb and forefinger is applied to the left front box edge 27 of the outer box 2, and the left front box edge 27 is pushed inward in the width direction of the outer box 2. That is, in opening operation of the hinge lid 3 which concerns on this embodiment, it deform | transforms so that it may approximate to a rectangle by performing twisting operation which twists the outer box 2 which has a cross section of a parallelogram.

  As described above, the right frame edge 44 of the inner frame 4 has an inclined edge that extends obliquely upward so that the region protruding above the opening end 20 of the outer box 2 is inclined inward in the width direction of the outer box 2. It is formed as a portion 44A. Further, the right side wall 23 of the outer box 2 connects the front wall 21 and the rear wall 22 as an inclined side wall that extends from the front wall 21 so as to be inclined rearward in the width direction of the outer box 2.

  Therefore, when the twisting operation of the outer box 2 is performed, the inclined edge portion 44A is changed from the state shown in (a) before the twisting operation (hereinafter referred to as "original state") to the state shown in (b). Rises toward the front side (front side) of the outer box 2. That is, in the original state, the inclined edge portion 44 </ b> A that has been accommodated in the plane of the front wall 21 rises out of the plane of the front wall 21 with the twisting operation, and tilts toward the front of the outer box 2.

  According to this, in the original state shown in (a), the tip (upper end) of the inclined edge portion 44A arranged in contact with or close to the right front entering corner on the inner surface side of the hinge lid 3 is the outer box 2. By tilting forward, the tip of the inclined edge portion 44A pushes up the hinge lid 3 while contacting the inner surface (back surface) side of the right front lid edge portion 36. The position where the tip of the inclined edge portion 44A contacts the inner surface of the hinge lid 3 is gradually shifted from the upper end side on the inner surface side to the lower end side of the right front lid edge portion 36 with the tilting operation of the inclined edge portion 44A. go. Thus, the hinge lid 3 is opened with the hinge 5 as a fulcrum by the tip of the inclined edge 44A in the inner frame 4 sliding or sliding inside the right front lid edge 36. .

  The state shown in (c) shows a state in which the amount of twisting of the outer box 2 accompanying the twisting operation is further increased compared to the state shown in (b). That is, the opening degree of the hinge lid 3 is larger in the state shown in (c) than in the state shown in (b). As the degree of opening of the hinge lid 3 increases, the tip of the inclined edge 44A that slides along the back surface of the right front lid edge 36 in the hinge lid 3 reaches the lower end of the right front lid edge 36 at a certain point. To reach.

  Thereafter, the sliding contact state between the tip of the inclined edge 44A and the back surface of the right front lid edge 36 in the hinge lid 3 is released, but the tip of the inclined edge 44A is separated from the back surface of the right front lid edge 36. At the moment, the hinge lid 3 is bounced and flipped up by the inclined edge 44A. As a result, the hinge lid type box 1 sequentially shifts from the state shown in (c) to the state shown in (d). In the state shown in (d), the hinge lid 3 is completely opened so that the inner cigarette C can be taken out. It becomes. As described above, according to the hinge lid type box 1 according to the present embodiment, the hinge lid 3 can be easily opened with one hand.

  When a rod-shaped article such as a cigarette C is stored in the outer box 2 as in the hinge lid type box 1 according to this embodiment, the upper end portion of the cigarette C is higher than the tip end (upper end) of the inclined edge portion 44A. Located (see FIG. 2). Accordingly, during the transition from the state shown in (c) to the state shown in (d), the hinge lid 3 is also brought into contact with the upper end side of the cigarette C by the twisting operation of the outer box 2 by the consumer. While opening. The contact state between the cigarette C (inner pack) and the hinge lid 3 assists the opening operation of the hinge lid 3, thereby making it easier to open the hinge lid 3.

  Further, the inner frame 4 of the hinge lid type box 1 extends upward to a position where the upper end portion 42A of the right side frame 42 connected to the front frame 41 via the inclined edge portion 44A is higher than the upper end of the inclined edge portion 44A. It is installed. By adopting such a structure, the hinge lid 3 can be opened more reliably even when the remaining number of cigarettes C stored in the outer box 2 is reduced when the twisting operation is performed.

  That is, even when the inclined edge 44A of the inner frame 4 that is in sliding contact with the back surface of the right front lid edge 36 is separated from the right front lid edge 36 during the twisting operation on the outer box 2, the right side frame 42 The upper end portion 42 </ b> A is held in contact with the right side wall 33 of the hinge lid 3. According to this, even after the sliding contact state of the inclined edge portion 44 </ b> A with respect to the inner surface of the hinge lid 3 is released, the upper end portion 42 </ b> A of the right side frame 42 is held in contact with the right side wall 33 of the hinge lid 3. Then, when the upper end portion 42A of the right side frame 42 that has been elastically deformed by the twisting operation is released, the driving force for opening the hinge lid 3 can be obtained by flipping the right side wall 33 of the hinge lid 3 and jumping up. 3 can be opened more suitably.

  Further, the hinge lid type box 1 according to the present embodiment is provided with slits 6 at both ends of the hinge 5 that hinge-connects the hinge lid 3 and the outer box 2. In particular, by providing the slit 6 at the end of the hinge 5 where the inclined edge 44A of the inner frame 4 is provided forward, that is, the end located on the right side wall 23 side, the following There is an effect.

  That is, when a consumer who tries to open the hinge lid 3 of the hinge lid type box 1 twists the outer box 2, the right end region of the rear wall 22 in the outer box 2 is more easily deformed. Thereby, the displacement amount of the right rear box edge part 28 at the time of twisting of the outer box 2 can be increased. As a result, it is possible to further increase the degree of inclination when the inclined edge portion 44 </ b> A of the inner frame 4 is inclined to the front side (forward) of the outer box 2. Therefore, since the inner surface of the hinge lid 3 can be repelled more vigorously by the inclined edge portion 44A of the inner frame 4 or the upper end portion 42A of the right side frame 42, the hinge lid 3 can be suitably opened. When installing the slit 6 at the end of the hinge 5, at least the end of the hinge 5 on the end on the right wall 23 side where the inclined edge 44 </ b> A of the inner frame 4 is provided in front. A slit 6 may be provided.

  Furthermore, the left side wall 24 of the outer box 2 according to the present embodiment connects the front wall 21 and the rear wall 22 as an inclined side wall that inclines and extends from the front wall 21 to the rear in the width direction of the outer box 2. . In this way, as a result of the left side wall 24 and the right side wall 23 of the outer box 2 forming a pair of parallel inclined side walls, the outer box 2 having a parallelogram-shaped cross section is obtained. By adopting the above structure, when the consumer twists the outer box 2, the amount of twisting of the outer box 2 can be increased, so that the inclined edge 44 </ b> A of the inner frame 4 is positioned on the front side (front side) of the outer box 2. ) To a greater degree of tilting. Therefore, it becomes easier to open the hinge lid 3 by the twisting operation of the outer box 2.

  Moreover, the front wall 31 of the hinge lid 3 in the hinge lid type box 1 is formed from the front wall panel P14 and the front wall reinforcing panel P19 of the main blank B1 shown in FIG. Here, the front wall reinforcing panel P19 is narrower than the front wall panel P14. Therefore, when the front wall reinforcing panel P19 is overlapped and bonded to the front wall panel P14, the vicinity of the connection portion between the front wall 31 of the hinge lid 3 and the right side wall 33 is formed to be one step thinner than other portions. As described above, in the front wall 31 of the hinge lid 3, a groove is formed on the back surface of the right front lid edge portion 36 by reducing the thickness in the vicinity of the connecting portion with the right side wall 33 as compared with other portions. become. Since this groove is formed along the inclined edge portion 44A of the inner frame 4, it serves as a guide when the tip (vertex) portion of the inclined edge portion 44A slides or slides on the back surface of the right front lid edge portion 36. Function. Thereby, the hinge lid 3 can be opened more suitably.

  Next, an inclination angle (hereinafter referred to as an “inclined edge angle”) φ at which the inclined edge portion 44A of the inner frame 4 is inclined with respect to the right front box edge portion 26, and a length of the inclined edge portion 44A (hereinafter referred to as “inclined edge angle”). "Inclined edge length".) The combination of L will be described. FIG. 9 is an explanatory diagram for explaining a method of setting the inclined edge angle φ and the inclined edge length L in the inner frame 4, and specifically shows a right side view of the hinge lid type box 1. L3 in FIG. 9 indicates a locus of a position through which the lower end portion of the front wall 31 passes when the hinge lid 3 is opened. As a result of intensive studies, the inventor can open the hinge lid 3 more easily when the outer box 2 is twisted by setting the inclined edge angle φ and the inclined edge length L according to the following procedure. I found.

  The first reference line LB1, the second reference line LB2, and the third reference line LB3 in the figure are reference lines used for setting the inclined edge angle φ and the inclined edge length L, respectively. Each reference line is obtained by connecting the reference point on the locus L3 and the lower end portion of the front wall 31 when the hinge lid 3 is closed. Here, when the length of each reference line LB1, LB2, LB3 is adopted as the inclined edge length L, as the inclined edge angle φ corresponding to each inclined edge length L, each reference line LB1, LB2, LB3 and It is preferable to adopt an angle formed by the front wall 21 (the right front box edge portion 26) of the outer box 2. According to this setting method, the inclined edge length L can be shortened as the inclined edge angle φ is small, and conversely, the inclined edge length L needs to be increased as the inclined edge angle φ is large. By setting the combination of the inclined edge angle φ and the inclined edge length L in this way, the hinge lid 3 can be suitably opened when the outer box 2 is twisted.

  Here, each reference point on the locus L3 and the hinge 5 are connected by a line segment. The combination of the inclined edge angle φ and the inclined edge length L determined by the second reference line LB2 obtained when the obtained line segment is substantially horizontal is determined by the other reference lines LB1 and LB3. As compared with the combination of the determined inclined edge angle φ and the inclined edge length L, it was found that the lid opening property of the hinge lid 3 was most excellent. Here, the inclined edge angle φ corresponding to the second reference line LB2 is 164 °. As a result of intensive studies by the present inventor, it is possible to set the inclined edge angle φ to about 164 ± 10 ° and to set the corresponding inclined edge length L according to the above method. 3 was found to be preferable from the viewpoint of the lid opening property.

<Modification>
Next, a modification of the hinge lid type box 1 according to the embodiment will be described. In the above-described hinge-lid box 1, the outer box 2 has a parallelogram in cross-sectional shape.
