JP 2011-255916 A Japanese Patent No. 5579784

In the container described in Patent Document 1, when the mold for molding is consumed, the engagement of the fasteners becomes sweet, and the container may open unintentionally.
On the other hand, since the container of Patent Document 2 includes a plurality of claws in the circumferential direction, it is possible to suppress opening of the container during conveyance or stirring. However, even if it is attempted to take out the product after purchase, it cannot be taken out easily. More specifically, the container of Patent Document 2 needs to be pulled in a direction in which the hemispheres are separated from each other while being elastically deformed by simultaneously pushing a plurality of claws. Therefore, it may be difficult for a child to take out the product.

  The present invention has been made in view of the above circumstances, and can prevent the container from being unintentionally opened at the time of conveyance or stirring, and can be easily opened when taking out a stored product. A possible container is provided.

In order to solve the above problems, the present invention has the following configuration.
According to the first aspect of the present invention, the storage container can be fitted into the first half part forming the concave first internal space and the inside of the opening edge part of the first half part by its elasticity. A second half portion having an opening edge portion and forming a concave second internal space, and fitting the opening edge portion of the first half portion to the opening edge portion of the second half portion. Thus, the storage container in which one storage space is formed by the first internal space and the second internal space, the opening edge portions of the first half portion and the second half portion. A hinge portion that connects each other, and an engagement portion that can be engaged and disengaged at a position spaced from the hinge portion between the opening edges of the first half portion and the second half portion, The engaging portion is a claw portion provided on either the inner side surface of the opening edge portion of the first half portion or the outer side surface of the opening edge portion of the second half portion. A locking recess provided on either the inner surface of the opening edge of the second half or the outer surface of the opening edge of the second half and capable of locking the claw And a recessed portion that is provided in the second half portion and that is recessed from the opening edge portion of the first half portion to the inside of the housing space at a position where the engaging portion is disposed.

As described above, since the second half portion is provided with the concave portion, the engaging portion is arranged even when a large number of storage containers are stored in the bag or the like and the storage container is pressed from the outside. It can suppress that it will be in the state where only the opening edge part of the 2nd half part of a position to be pressed. As a result, it is possible to prevent the storage container from being unintentionally opened during conveyance or stirring.
Furthermore, a gap is formed between the opening edge of the first half and the opening edge of the second half at the position where the engaging portion is disposed. Therefore, when it is desired to open the storage container, the recess can be pressed toward the inside of the storage container by trying to insert a finger into the gap. Therefore, the claw portion can be detached from the locking recess and the engagement by the engagement portion can be easily released.

According to the second aspect of the present invention, the storage container is configured such that the concave portion in the first aspect is separated from the opening edge portion of the first half portion toward the central portion in the circumferential direction in which the opening edge portion extends. It may be formed.
By comprising in this way, the shape of the clearance gap formed between the opening edge part of a 1st half part and the opening edge part of a 2nd half part part can be made into the shape which a finger | toe easily catches. Therefore, the engagement can be released more easily by the engaging portion.

According to the third aspect of the present invention, in the container according to the first or second aspect, the shape of each opening edge part of the first half part and the second half part is formed in a circular shape. The concave portion may have a concave curved surface.
By comprising in this way, the clearance gap which becomes so large that it goes to the center part of the circumferential direction where an opening edge extends can be formed easily. Furthermore, since the concave portion has a concave curved surface, it can be easily elastically deformed when the concave portion is pressed toward the inside of the container.

According to the fourth aspect of the present invention, in the storage container, the recess in any one of the first to third aspects is a circumference in which the opening edge extends from the opening edge of the second half. You may make it have a slit extended in the direction which cross | intersects a direction.
By comprising in this way, it becomes easy to bend a recessed part toward the inner side of a storage container. Therefore, the engagement by the engaging portion can be released with a smaller force.

According to the fifth aspect of the present invention, in the receiving container, the slit of the fourth aspect may be formed in the central portion of the recess in the circumferential direction in which the opening edge extends.
By comprising in this way, a recessed part can be bent more efficiently than the case where the slit is not formed in the center part.

According to the sixth aspect of the present invention, in the container, the engaging portions of the fourth or fifth aspect are provided on both sides of the slit in the circumferential direction in which the opening edge extends, and the opening You may distribute | arrange in the range in which the said recessed part is formed in the circumferential direction where an edge part extends.
By comprising in this way, unless the engagement of both engaging parts on both sides of the slit is released simultaneously, the container is not opened. Therefore, the reliability of engagement by the engagement portion can be improved. Further, when the container is opened, it is possible to simultaneously release the engagement of both engaging portions sandwiching the slit by simply inserting a finger into the central portion of the recess in the circumferential direction in which the opening edge extends. .

According to a seventh aspect of the present invention, in the storage container according to any one of the first to sixth aspects, an intermediate position between the hinge part and the engaging part in a circumferential direction in which the opening edge extends. In addition, an auxiliary engagement portion capable of engaging and disengaging the opening edge portion of the first half portion and the opening edge portion of the second half portion may be provided at a position closer to the hinge portion.
With this configuration, even when the engagement of the engaging portion is unintentionally released, the opening of the storage container can be suppressed by the auxiliary engaging portion. Furthermore, when the auxiliary engagement part is arranged at a position close to the hinge part, when opening the container, the opening edges of the first half part and the second half part located far from the hinge part By separating them, a large force can be applied to the auxiliary engagement portion with a small force by the principle of the lever. Therefore, even when the auxiliary engagement portion is provided, the storage container can be easily opened.

According to an eighth aspect of the present invention, in any one of the first to seventh aspects, the storage container is formed at a position facing the recess of the first half part, and the first half A protrusion projecting from the opening edge of the split part, and formed on the inner surface of the protrusion, the first half part and the second half part being fitted together, And a first rib protruding toward the outer surface of the recess.
By configuring in this way, the nail portion is detached from the locking recess by lifting the protruding portion with the belly of the finger from the state where the first half portion and the second half portion are fitted together, and the engaging portion The engagement by can be easily released. Further, since the first rib is formed from the inner side surface of the projecting portion toward the outer surface of the recessed portion, when the receiving container is transported, the projecting portion of the other receiving container has a gap between the projecting portion and the recessed portion. Intrusion can be suppressed. Therefore, when taking out the accommodated goods, it can be easily opened, and unintentional opening of the container during transportation can be reduced.

According to a ninth aspect of the present invention, in the eighth aspect, the container is provided in the concave portion, and the first half portion and the second half portion are fitted together, You may provide the 2nd rib which protrudes toward the inner surface of the said protrusion part from an outer surface.
Thus, it can suppress that the protrusion part of another storage container enters into the clearance gap between a 1st rib and a recessed part because the 2nd rib protrudes toward a protrusion part. As a result, unintentional opening of the container can be further reduced.

  According to the storage container, it is possible to prevent the container from being unintentionally opened during conveyance or stirring, and to easily open the stored product.

The second half portion 3 has a stepped portion D that is recessed inward in the radial direction at the opening edge portion 12b. The step portion D is formed in a strip shape having a uniform width along the opening edge portion 12b. The opening edge portion 12 b where the stepped portion D is formed can be fitted inside the opening edge portion 12 b of the second half portion 3. A thickness dimension t <b> 3 in the radial direction of the stepped portion D is a dimension equivalent to the thickness dimension t <b> 1 of the second half portion 3. Therefore, in a state where the opening edge 12b of the second half 3 is fitted inside the opening edge 12a of the first half 2, the second outer peripheral surface 19 of the second half 3 and the first half It arrange | positions so that the 1st outer peripheral surface 9 of the split part 2 may continue, and it will be in what is called a flush state.

  The concave portion 21 is formed at a position symmetrical to the hinge portion 4 in the circumferential direction of the opening edge portion 12b. The concave portion 21 is formed at a position facing the protruding portion 9a of the first half portion 2 in a state where the first half portion 2 and the second half portion 3 are engaged. The recess 21 is formed so as to be recessed inward from the extended surface obtained by extending the second outer peripheral surface 19 around the periphery in the radial direction of the opening edge 12b. In other words, the recess 21 is formed so as to chamfer part of the second outer peripheral surface 19. The concave portion 21 in this embodiment is formed into a spherical surface (concave curved surface) that is slightly concavely curved inward in the radial direction of the opening edge portion 12b. Thereby, the recessed part 21 is the center part 24 (refer FIG.2, FIG.3, FIG.6) in the circumferential direction of the opening edge part 12b in the state in which the 1st half part 2 and the 2nd half part 3 were engaged. ) Away from the inner peripheral surface 25 of the protrusion 9a (see the two-dot chain line in FIG. 2).

  As shown in FIGS. 1, 2, and 6, the concave portion 21 includes a slit 26. The slit 26 is formed in the central portion 24 of the recess 21. The slit 26 extends from the position of the opening edge 12b to the middle position of the height dimension h2 of the recess 21 (see FIG. 4) in the meridian direction (direction intersecting the circumferential direction in which the opening edge 12a extends). A chamfered portion 27 made of an inclined surface is formed at the base of the slit 26 in this embodiment.

  The claw portion 22 is formed on the outer surface 21 a of the recess, that is, the second outer peripheral surface 19 of the second half portion 3, and constitutes the engaging portion 5 together with the locking hole portion 10 of the first half portion 2 described above. The nail | claw part 22 protrudes toward the outer side from the outer surface 21a of the recessed part 21 in the position corresponding to the latching hole part 10, respectively. The nail | claw part 22 is made into the magnitude | size which can be immersed in the latching hole part 10, respectively. The claw portion 22 includes a guide surface 28 and a locking surface 29.

Here, the first half 2 is swung from the position shown by the solid line in FIG. 1 to the position shown by the two-dot chain line to try to close the container 1. Then, the protruding portion 9 a hits the guide surface 28 and is gradually elastically deformed in a direction away from the recess 21. As a result, the protrusion 9 a goes around the outside of the recess 21. Thereafter, when the position of the claw portion 22 overlaps with the position of the locking hole portion 10, the claw portion 22 is immersed in the locking hole portion 10 by the elastic force of the protruding portion 9 a.

  When the locking surface 29 is immersed in the locking hole 10, the locking surface 29 faces the inner peripheral surface 25 at the end in the longitudinal direction of the locking hole 10 in parallel. This locking surface 29 restricts the protrusion 9 a from swinging in the opening direction of the container 1 with respect to the recess 21. On the other hand, the locking surface 29 allows the protruding portion 9a to be elastically and relatively displaced from the concave portion 21 to the radially outer side of the opening edge portion 12b. The locking surface 29 is orthogonal to the direction in which the protruding portion 9a is relatively displaced with respect to the concave portion 21, and extends outward in the radial direction of the opening edge portion 12b. The locking surface 29 in this embodiment has a curved surface corresponding to the arc surface of the inner peripheral surface 25 at the end of the long hole 10 a of the locking hole 10.

  As shown in FIGS. 1 and 2, the second rib 21 r is provided in the recess 21, and is fitted from the outer surface 21 a of the recess 21 with the first half 2 and the second half 3 fitted together. The protrusion 9a is formed so as to protrude toward the inner surface 9n. The second rib 21r in this embodiment extends from the two claw portions 22 in the same direction as the direction in which the slit 26 extends. The two second ribs 21r in this embodiment are arranged so that the outer edge of the protruding portion 9a extends from the position of the claw portion 22 along the center portion 24 in a state where the first half portion 2 and the second half portion 3 are fitted together. It extends to a position slightly outside the position of the portion 9ao, and its outer end 21ro is exposed to the outside. The outer end 21ro of the second rib 21r is chamfered by a convex curved surface. Here, the second rib 21 r in this embodiment is formed integrally with the claw portion 22. Thus, by forming the 2nd rib 21r and the nail | claw part 22 integrally, the intensity | strength of the nail | claw part 22 can be improved and it can make it easy to pull out from a metal mold | die when shape | molding.

  The second ribs 21r are respectively arranged on the outer sides of the two first ribs 9r in the circumferential direction of the opening edge 12a in a state where the first half 2 and the second half 3 are fitted together. . Furthermore, the second rib 21r is closer to the inner surface 9n than the inner edge 9ri of the first rib 9r from the outer surface 21a of the recess 21 in a state where the first half 2 and the second half 3 are fitted together. Projects to the position. The second ribs 21r are formed so that the protruding amount is smaller than that of the claw portion 22.

The auxiliary claw portion 23 constitutes the auxiliary engagement portion 6 together with the auxiliary locking hole portion 11. These auxiliary claw portions 23 include an auxiliary claw portion main body 30 and an auxiliary locking claw 31.
The auxiliary claw body 30 extends in the meridian direction and protrudes from the opening edge 12b. Auxiliary slits 32 are formed on both sides of the auxiliary claw body 30 in the circumferential direction of the opening edge 12b. These auxiliary nail | claw part main bodies 30 become the width dimension which can be bent easily by elastically deforming to the radial direction of the opening edge part 12b.

  The auxiliary claw 31 is formed at the end of the auxiliary claw body 30. These auxiliary locking claws 31 can be locked to the auxiliary locking portion main body 14 of the first half portion 2 described above. The auxiliary locking claw 31 protrudes outward in the radial direction of the opening edge 12b. In the auxiliary locking claw 31 in this embodiment, an auxiliary guide surface 34 is formed on the outer side in the radial direction of the opening edge 12 b and on the end side of the auxiliary claw body 30. The auxiliary guide surface 34 is an inclined surface that faces the auxiliary locking portion main body 14 and closes to the outer side in the radial direction of the opening edge portion 12b when the container 1 is closed.

As shown in FIG. 2, the auxiliary engagement portion 6 described above is disposed at a position closer to the hinge portion 4 than the intermediate position between the hinge portion 4 and the engagement portion 5 in the circumferential direction of the opening edge portion 12 b. . The auxiliary engagement portions 6 in this embodiment are formed at symmetrical positions with the hinge portion 4 and the engagement portion 5 in between in the circumferential direction of the opening edge portion 12b.
Here, the first outer wall 8 of the first half portion 2 and the second outer wall 18 of the second half portion 3 in this embodiment each have a plurality of (for example, four) through holes 33. Yes.

  The hinge portion 4 is formed in a flat plate shape in which a groove 4a (see FIG. 3) is formed in the width direction. The hinge part 4 is formed integrally with the first half part 2 and the second half part 3. The hinge portion 4 is formed of a resin having sufficient flexibility and elasticity that does not break even when bent in a direction orthogonal to the groove 4a.

  Therefore, according to embodiment mentioned above, when the 2nd half part 3 is equipped with the recessed part 21, when many storage containers 1 are accommodated in a bag etc. and the storage container 1 is a state pressed from the outside. Even so, it can be suppressed that only the opening edge portion 12b of the second half portion 3 is pressed at the position where the engaging portion 5 is disposed. In other words, since the protruding portion 9a comes first than the concave portion 21, it is possible to suppress only the concave portion 21 from being pressed from the outside. As a result, it is possible to prevent the storage container 1 from being unintentionally opened during conveyance or stirring.

  Furthermore, in the engaging part 5, a gap is formed between the opening edge part 12 a of the first half part 2 and the opening edge part 12 b of the second half part 3. Therefore, when the storage container 1 is desired to be opened, the recess 21 can be pressed toward the inside of the storage container 1 by inserting a finger into the gap. Therefore, the nail | claw part 22 can be removed from the latching hole part 10, and engagement by the engaging part 5 can be easily cancelled | released with little force.

  Furthermore, the concave portion 21 is formed so as to be separated from the protruding portion 9a of the first half portion 2 toward the central portion 24 in the circumferential direction in which the opening edge portion 12b extends, so that the concave portion 21 and the protruding portion 9a The shape of the gap formed between the two can be changed to a shape in which a finger is easily caught. Therefore, the engagement by the engaging portion 5 can be released more easily.

  Further, the opening edge portions 12a and 12b of the first half portion 2 and the second half portion 3 are formed in a circular shape, and the concave portion 21 has a concave spherical surface (concave curved surface). A gap that becomes larger toward the central portion 24 in the circumferential direction in which the edge portion 12b extends can be easily formed. Furthermore, since the concave portion 21 has a spherical surface, it can be easily elastically deformed when the concave portion 21 is pressed toward the inside of the container 1.

  Furthermore, since the recessed part 21 has the slit 26 and the slit 26 is formed in the center part 24 of the recessed part 21, the recessed part 21 can be efficiently bent toward the inner side of the storage container 1. FIG. Therefore, the engagement by the engagement portion 5 can be easily released with a smaller force.

  Furthermore, since the engaging portions 5 are arranged on both sides of the slit 26, the container 1 is not opened unless the engaging portions 5 of the both sides of the slit 26 are disengaged at the same time. Therefore, the reliability of engagement by the engagement portion 5 can be improved. On the other hand, when the container 1 is opened, both engagements with the slit 26 sandwiched by simply inserting a finger into the central portion 24 of the recess 21 in the circumferential direction in which the opening edges 12a and 12b extend. The engagement of the part 5 can be released simultaneously.

  Furthermore, by providing the auxiliary engagement portion 6, it is possible to suppress the opening of the container 1 by the auxiliary engagement portion 6 even when the engagement of the engagement portion 5 is released unintentionally. Further, since the auxiliary engagement portion 6 is disposed at a position close to the hinge portion 4, when the container 1 is opened, a large force is applied to the auxiliary engagement portion 6 with a smaller force due to the principle of the lever. Can be made. More specifically, when the opening edge 12b of the first half 2 and the second half 3 located far from the hinge 4 is a force point, the hinge 4 is a fulcrum, and the auxiliary engagement portion 6 is an action point. The distance from the force point to the fulcrum can be made larger than the distance from the action point to the fulcrum. Therefore, even when the auxiliary engagement portion 6 is provided, the storage container 1 can be easily opened.

  Furthermore, the engaging portion 5 of the above-described embodiment has a simple structure in which the claw portion 22 is immersed in the long hole 10a. Therefore, for example, even when the mold for molding the container 1 is somewhat consumed, it is possible to suppress the engagement portion 5 from being unintentionally released.

  Furthermore, by providing the first rib 9r, the protrusion portion 9a is lifted by the belly of the finger from the state where the first half portion 2 and the second half portion 3 are fitted together, so that the claw portion 22 is locked into the locking hole. The engagement with the engaging portion 5 can be easily released by being detached from the portion 10. Furthermore, since the first rib 9r is formed from the inner side surface 9n of the protruding portion 9a toward the outer surface 21a of the concave portion 21, when the receiving container 1 is transported, the protruding portion 9a of the other receiving container 1 is Intrusion into the gap between the protrusion 9a and the recess 21 can be suppressed. Therefore, when taking out the goods stored in the storage container 1, it can be easily opened, and unintentional opening of the storage container 1 during transportation can be reduced.

  Furthermore, since the 2nd rib 21r protrudes toward the protrusion part 9a, it can suppress that the protrusion part 9a of the other container 1 etc. enter | penetrate into the clearance gap between the 1st rib 9r and the recessed part 21. FIG. As a result, unintentional opening of the storage container 1 can be further reduced.

The present invention is not limited to the configuration of the above-described embodiment, and the design can be changed without departing from the gist thereof.

Furthermore, in embodiment mentioned above, the case where the latching hole part 10 had the long hole 10a by which the nail | claw part 22 was latched was demonstrated. However, it is not limited to the long hole shape as long as it is a hole in which the claw portion 22 is locked.

  Furthermore, in the above-described embodiment, the case where the claw portion 22 has the guide surface 28 has been described, but the guide surface 28 may be omitted. Similarly, although the case where the auxiliary locking claw 31 has the auxiliary guide surface 34 has been described, the auxiliary guide surface 34 may be omitted.

  Furthermore, in embodiment mentioned above, the case where the locking hole part 10 was formed in the 1st half part 2 and the nail | claw part 22 was formed in the 2nd half part 3 was demonstrated. However, the locking hole 10 may be provided in the second half 3 and the locking hole 10 may be provided in the first half 2.
