Description

  The present invention is a box-shaped container composed of a lid part and a housing part, and is formed by folding the folding part along folding lines formed on both sides of the folding part formed in the lid part. It is related with the box-shaped container in which the folding front-end | tip part and the cut | notch part formed in the said accommodating part lock toward the opening direction of the said cover part.

  Conventionally, a box-shaped container is known as an outer packaging box. This box-shaped container is composed of a storage part for storing the contents and a lid part for covering the storage part, and in particular, the folding part formed in the cover part is fitted into the notch part formed in the storage part. The accommodating part and the lid part are connected by being formed freely. Specifically, as shown in FIG. 3 (a), when the lid is opened and closed, the folds 4 are formed on both sides of the fold 4 by grasping the grip 5 formed on the lid and pulling it forward. Turn along the fold line 7. At this time, since the left and right folding lines 7 sandwiching the folding section 4 are arranged on the same straight line t, the folding section 4 bends while maintaining a horizontal plane. (For example, Patent Document 1) For this reason, the opening and closing operation frequently performed not only gradually loses the strength of the folding portion 4 but also the strength of the folding line 7, so that the lid portion easily becomes easier with time. There was a drawback of opening the lid. Further, when the strength of the tip portion 10 of the folding portion 4 is lost, there is a drawback that the tip portion 10 is bent when the tip of the folding portion when the lid is closed comes into contact with the cut portion, and the lid cannot be smoothly closed.

  Also, when opening, the initial opening is performed by pulling up and separating the gripping portion upward. However, since the conventional gripping portion 5 has the folding line 7 on the straight line t, the gripping portion 5 is cut off and then cut in an oblique direction. The operation of cutting off the lid along the line is performed. Therefore, it was difficult to open the grip part because the force to peel it off was not transmitted until the gripping part was sufficiently raised. Further, even if the gripping part is cut off, there is no escape area of the tip provided above the gripping part until the lid is cut off, the tip is bent along the straight line t, and the lid is cut off to some extent. Until then, there was a problem that the tip would be burdened.

FIG. 1 is a perspective view showing an example of a box-type container 1 having a lid part formed by cutting out a part of the container part of the present invention.
The box-shaped container 1 has a lid portion 2 formed by cutting a part of the housing portion 3, and the lid portion 2 is closed so as to cover the housing portion 3.
A semicircular cut 9 is formed above the opening start position of the lid 2, and a fold line 7 for folding a part of the lid 2 is formed from both ends of the cut 9. ing. A portion surrounded by the folding line 7 and the semicircular cut 9 forms a folding part 4. In particular, the semicircular portion of the semicircular cut 9 forms a folding tip 10, and the folding tip 10 is inserted into or pulled out from a cut 6 formed in the housing 3 described later. Thus, the lid 2 is opened and closed. A substantially rectangular gripping part 5 is formed continuously from the folding part 4, and when opening the lid, the folding part 4 is bent along the folding line 7 by pinching the gripping part 5 and causing it to the front. After standing up in a substantially vertical direction with respect to the cut portion 6, the folding tip portion 10 is pulled out from the cut portion 4 by continuously pulling the grip portion 5 toward the front. When closing the lid, the lid is closed by the reverse operation.

As shown in FIG. 2A, the folding line 7 is formed on the same straight line t connecting the line ends 7i inside the folding lines 7 so that the folding line 7 formed on both sides of the semicircular cut 9 Since it is formed in a square shape with an angle α downward, when the fold portion 4 bends along the fold line 7 (FIG. 2B), the fold portion 4, the grip portion 5, and the tip of the fold portion 10 is a curved surface.
Then, when the lid portion 2 is opened, if the center portion of the grip portion 5 is gripped and raised upward u as shown in FIG. 2 (b), the fold portion 4 is bent along the fold line 7. At this time, since the folding line 7 has the angle α, both the far ends 7o of the folding line 7 are pulled in the center direction A of the grip portion 5. As a result, the central portion c of the grip portion 5 rises upward u and forms a curved surface.

3A is a front view when the conventional folding line 7 is formed on the same straight line t, and FIG. 3B is a front view when the folding line 7 of the present invention has an angle α (upper figure), respectively. FIG. 2 shows a cross-sectional view in the lateral direction (lower figure).
In the conventional case, as shown in FIG. 3A, when the grip portion 5 is lifted, the folding portion 4 bends along the folding line 7 while maintaining the horizontal plane H. At this time, since the force is not yet transmitted to the lid portion 2, the lid portion 2 is not cut off, and only the grip portion 5 is cut off.
Then, after the grip portion 5 is cut off, the lid portion 2 is further opened in the direction in which the angle is opened (reverse C-shaped direction), whereby the lid portion 2 is initially opened.

On the other hand, in the present invention, when the grip portion 5 is lifted as shown in FIG. 3B, the grip portion 5, the fold portion 4, and the fold tip portion 10 become the curved surface W. The strength of 10 is dramatically improved.
Thereby, even if the opening / closing operation is repeated frequently, the folded portion tip 10 is not crushed.
Further, since the folding line 7 is formed not in the same straight line t but in a square shape having an angle α in the downward direction, the grip portion 5 is not bent at a right angle. For this reason, when the cover part 2 slides upward by vibration etc., the folding front-end | tip part 10 does not come off from the notch part 6 easily.

  Further, when the grasping portion 5 starts to be cut at the time of initial opening, the folding portion tip 10 starts to stand up, and both outer sides of the folding line 7 are lifted with the folding portion tip 10 as a fulcrum. Thereby, since the cutting line of the lid part 2 starts to be lifted simultaneously with the lifting of the gripping part 5, it is possible to smoothly shift from the cutting of the gripping part 5 to the cutting of the lid part 2.

FIG. 4 shows a development view of the box-shaped container 1 shown in FIG.
The accommodating part 3 is formed from four side surfaces (s1 to s4), two top plate surfaces (p1, p2), and seven bonding surfaces (d1 to d7). Each surface is in contact with each other through a fold line 15, the surface is folded in the vertical direction along the fold line 15, and the respective surfaces are bonded to each other by bonding surfaces (d 1 to d 7). Become. On the other hand, the lid portion 2 is composed of a surface obtained by cutting out a continuous part of one top plate (p1) and one side surface (s1) in contact with the top plate (p1). In contact with the housing 3. The cut line 13 is formed so that the top plate surface (p1) is cut into a square shape on the top plate surface (p1), and the side surface (s1) is cut into a substantially triangular shape on the side surface (s1). Is formed. In addition, a rectangular gripping portion 5 having a size that can be gripped with a finger when the lid portion 2 is opened and closed is formed near the apex of the triangle formed on the side surface (s1).

A substantially semicircular cut 9 is formed in the vicinity of the grip 5, and a fold line 7 is formed from both sides of the cut 9 to the end of the lid 2.
On the other hand, the notch 6 for inserting the fold end 10 is formed on the bonding surface (d1) to which the side surface (s1) having the fold 4 is bonded, and the substantially T-shaped notch 6 is formed. Is formed. The cut in the horizontal direction of the cut portion 6 is formed to be slightly larger than the width of the base A of the fold portion tip 10, and the vertical cut is formed with a length substantially the same as the height B of the fold portion tip 10. Is done. By forming the cut portion 6 in a T shape in this manner, even if the fold portion tip 10 is a curved surface, the opening area of the cut portion 6 is increased so that the fold portion tip 10 can be easily inserted. Is possible. In particular, as shown in FIG. 5, the folding line 7 is formed to be inclined in the shape of a letter C with an angle α downward from the same straight line t connecting the line ends 7i inside the folding lines 7. Thereby, the surface of the folding part 4 forms a curved surface, and there exists an effect which the intensity | strength of the folding part front-end | tip 10 increases dramatically.

  Further, as shown in FIG. 11 (a2), the left and right folding lines 7 formed on both sides of the folding section formed in the conventional lid section 2 are formed on the same straight line. In comparison, it is necessary to increase the height of the gripping part 5, and inevitably, the angle G of the cut line 15 must be gently formed. On the other hand, in the case of the present invention (FIG. 11 (a1)), the space of the folding portion 4 can be used as an extension of the gripping portion 5 even if the height of the gripping portion 5 is made low. Since the angle F can be formed at an acute angle (F <G), the lid 2 can be easily opened along the cut line 15 at the time of initial opening.

In particular, as shown in FIG. 15, in the case of a box-shaped container in which a lid is formed through a zipper, conventionally, since there is only an insertion piece that is about half the width of the zipper, it is difficult to make a kohaze type. The plug-in type as shown in a) was mainly used.
Since the folding mechanism of the box-shaped container of the present invention is formed in a C-shape, as shown in FIG. 15 (b), the area of the gripping part is sufficiently large even if the width of the zipper is small. Therefore, even with such a box-type container, it is possible to apply a squeeze-type locking mechanism.

FIG. 6 is a perspective view showing an example of the box-shaped container 1 including the lid part and the container part of the present invention.
According to the present invention, even when the lid opening end z of the lid portion 2 is formed with a smooth curve, the folding portion 4 can be formed in a rhombus shape by forming the folding line 7 in a square shape. is there.
As shown in FIG. 6, the folding line 7 formed in the cover part 2 is formed in a square shape, and the folding part 4 is formed between the vertices of the square shape. Thereby, it is not necessary to separately form a gripping part on the lid part 2, and the space surrounded by the curve of the lid part 2 and both folding lines 7 forms a rhombus shape, so this part can be easily grasped with a finger, In addition, the design is improved.

FIG. 7 shows a development view of the box-shaped container 1 shown in FIG.
The accommodating part 3 is formed from three side surfaces (s2, s3, s4), two top plate surfaces (p2, p3), and six bonding surfaces (d1 to d6). The respective surfaces are in contact with each other via a fold line 15, and the surfaces are folded vertically along the fold line 15 to bond the respective surfaces with the bonding surfaces (d <b> 1 to d <b> 6) to form a hexahedral container. On the other hand, the lid portion 2 is a continuous surface of one side surface (s1) in contact with one top plate (p2) of the housing portion 3 and one top plate (p1) in contact with the side surface (s1). Consists of. One side of the lid opening tip z of the top plate (p1) of the lid 2 has a smooth uneven curve, and a semicircular cut 9 is formed at an upper position from the apex of the convex portion of the curve. Yes. Then, a C-shaped fold line 7 is formed with both sides of the notch 9 as vertices, and a portion surrounded by both the fold lines 7 forms a fold portion 4. On the other hand, the notch part 6 for inserting the folding part tip 10 of the folding part 4 is formed on one top surface (p3) of the accommodating part 3.

  The cut portion 6 has a T-shape including a horizontal cut and a vertical cut, and the opening area of the cut portion 6 is large even if the fold tip 10 is a curved surface. Since it increases, it is possible to insert the folding front-end | tip part 10 easily. Furthermore, by forming a cut substantially downward from both ends of the horizontal cut, the opening area of the cut portion 6 is further increased, so that the folding tip can be easily turned into the cut portion. Insertion becomes possible.

  Moreover, the bending part of the folding part may be convex upward or downward depending on how the consumer grips the folding part. In this case, as shown in FIG. 12 (b), the horizontal cut 58 of the cut portion 6 has a downward curved shape, or an upward curved shape. In addition, there is an effect that the tip end portion of the fold is easily inserted into the cut portion.

  In particular, as shown in FIG. 8, the folding line 7 is inclined in the shape of a letter C by being inclined downward at an angle α from the same straight line t connecting the inner line ends (7 i) of both folding lines 7. ing. Therefore, at the time of opening, as shown in FIG. 9, since the folding part 4 forms the curved surface W, there exists an effect which the intensity | strength of the folding part front-end | tip 10 increases dramatically. In addition, after the initial opening, the curved surface W of the folding portion 4 is wrinkled, so that the finger is easily caught on the curved surface W at the next opening.

  Furthermore, as shown in FIG. 10, the folding line may be curved (7 ′). By forming the folding line into a curved line, the folding part further forms a curved surface W along the curved line. There is an effect that becomes easy. In addition, if the lower part of the folding part 4 is recessed (deboss D), the folding part 4 has a better finger grip and is easier to open.

  Further, in the conventional folding line 7, when the tip of the lid 2 has a shape that draws a gentle curve, as shown in FIG. It becomes difficult. However, in the case of the present invention (FIG. 11 (b1)), since the folding portion 4 has a rhombus shape and the length K of the grip portion becomes short (K <L), the grip portion is effectively formed from a limited space. It becomes possible.

Thus, the inclination angle α from the same straight line t connecting the inner line ends (7i) of the C-shaped folding line is preferably 30 °, but may be 30 ° ± 15 °. The folding line 7 is not limited to a straight line, and may be a gentle curve, a broken line, two or more parallel lines, and the like. In particular, when the box-shaped container is a paper box and the paper quality is thick (310 g / m ² to), it is more preferable that the fold line is a notched lead rule or perforation.

  In addition, the box-shaped container of the present invention has a folded portion formed on one surface (53) of a plurality of surfaces, as shown in FIG. 12, with the lid portion comprising a plurality of surfaces (51, 52, 53, 54). (55) is formed on the folding front end portion 57 formed by folding along a folding line (59) formed from both ends of the folding portion, and on the other surface (54) of the plurality of lid portions. It may be applied to the box-shaped container 50 that is locked by being fitted with the cut portion (58).

12A shows a state in which the two lid portions 53 and 54 of the box-type container 50 are closed, and FIG. 12B shows a state in which the two lid portions 53 and 54 are opened. In this case, the grip part 55, the folding line 59, the folding tip part 57 are formed in the lid part 53, and the notch part 58 is formed in the other lid part 54, so that the lid part can be locked as described above. In this case, since the folding line 59 is formed in a letter C, the lock is not easily released.
In particular, when locking such a lid portion composed of a plurality of surfaces (51, 52, 53, 54), the notch portion 58 has a curved shape in accordance with the curved surface formed by the folding tip portion 57. As a result, there is an effect that the locking is further facilitated.

  Further, a case-like container 41 made of plastic as shown in FIG. 13 is extended to the lid part 42 to form a grip part 46, a fold line 47, a fold tip 48, and the container part. You may apply to the container 41 which has the notch part 49 in the upper surface 56, and has the lock mechanism which can be latched.

  FIG. 14A shows a case where the lid D4 is formed on the upper surface, and the four surfaces at the top of the container are opened and closed to form an opening. Furthermore, when a cylindrical container as shown in FIG. 14B is accommodated, the band-like surface (E5) may form a lid.

Furthermore, the box-shaped container of the present invention may be applied to a container in which a lid part and a container part are formed via a zipper J as shown in FIG. In this case, in the conventional method in which the folding lines are formed horizontally, a part of the width B of the zipper J is used as the gripping portion 4, so that the gripping portion 4 can be formed with a length p that is about half the zipper width B. Since it was not possible and it was difficult to adopt the KOHASE type, the method of inserting the tip of the grip portion 4 downward as shown in FIG.
However, as shown in FIG. 15B, even when the zipper width B is narrow, the length p ′ of the grip portion 4 is sufficiently increased by applying the C-shaped folding lines (7, 7 ′). As a result, it is possible to form a kohaze lock mechanism.

  In the locking mechanism of the present invention, when a consumer grasps the folding part 4 and performs an opening operation, the curved surface W of the folding part 4 and the folding tip part 10 is usually as shown in FIG. When bending along the fold line 7, the curved surface W having a convex shape is naturally formed upward. Especially when the consumer performs the opening / closing operation by pinching the fold end 10 with the fingertip, When the width of the tip is smaller than the width of the folding tip 10 (finger width ≦ width of the folding tip 10 (usually about 15 mm or more)), as shown in FIG. A curved surface W is formed in a direction (downward) opposite to the curved surface W formed by the folding portion 4 along the fold.

  Thus, the locking mechanism of the present invention is not limited to the curved surface W formed by the folding portion forming an upward convex shape, but is curved downward or convex or waved upward and downward. In addition to providing a lock mechanism with better operability, the lock mechanism of the present invention can be applied to a wide variety of box-type containers.

  Further, the box-shaped container including the lock mechanism of the present invention is not limited to a paper box, but can be applied to a box-shaped container made of various materials such as plastic, multilayer film, paper coated with plastic resin.
