Description

[Technical Field]

[0001] The present invention relates to a lidded container consisting of a container body and a lid body that is provided to cover the opening of the container body, and in particular to a lidded container that stores detergents, medicines, chemicals, etc. and has a child lock function. [Background technology]

[0002] In recent years, detergent balls, in which detergent is packaged in a water-soluble film, have become known as laundry detergents and dishwasher detergents. These detergent balls have the advantage of being less susceptible to deterioration than liquid detergents, since the detergent is airtightly packed in the film and is configured so that the film is wetted with water and torn during use, allowing the detergent to spill out. However, because detergent balls look like jelly candy, there is a risk that children may accidentally ingest them. Therefore, it is recommended that they be stored in a container with a lid and a child-lock function, as described in Patent Document 1, for example. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-164085 Summary of the Invention [Problem to be solved by the invention]

[0004] The lidded container of Patent Document 1 has two or more locking parts on the lid, and is configured so that the lid can be opened by simultaneously releasing the locks of at least two of the locking parts. The two locking parts are spaced apart by a distance larger than the size of a child's hand, making them difficult to operate by children with small hands. However, while this child lock function is effective in preventing accidents caused by children's tampering, it requires time and effort to open the lid, which can be inconvenient for adults who use it on a daily basis, leaving room for improvement. Furthermore, in the lidded container of Patent Document 1, the locking parts are exposed, so there is a risk that the locking parts will be unexpectedly released and the lid will open due to vibrations or impacts during transportation or display.

[0005] Therefore, the object of the present invention is to provide a lidded container that maintains a child lock function to prevent the lid from being opened by children through mischief, etc., while also being easy for adults to open and preventing the lid from being accidentally opened due to vibrations or impacts during transportation, etc. [Means for solving the problem]

[0006] The container with lid of the present invention, which was developed to achieve the above object, A lidded container comprising a container body having an opening formed at an upper end and configured to store contents in a storage space through the opening, and a lid body that closes the opening to keep the storage space airtight, the lid body includes an annular lower lid disposed on the edge of the opening, and an upper lid rotatably connected to the lower lid via a hinge and fitted to an upper surface of the lower lid to close the opening, the top cover has at least one flap suspended from an outer edge of the top cover and having a free lower end; The lower lid has a through hole that opens from top to bottom, and the flap is inserted through the through hole, and a locking claw portion provided at the insertion portion is linked to a window hole in the flap to hold the upper lid immovable and prevent the upper lid from opening.However, an insertion locking portion is provided that releases the flap from being linked to the locking claw portion by pulling the free end outward inside the through hole while maintaining the insertion position of the flap, allowing the upper lid to rotate and open.

[0007] In the lidded container of the present invention, it is preferable that the lower lid is fixed and held to the edge of the opening.

[0008] In the lidded container of the present invention, the flap preferably comprises an elastic piece that is elastically deformable starting from the connection point with the top lid. [Effects of the Invention]

[0009] According to the lidded container of the present invention, the upper lid and the lower lid (container body) can be easily released from the connection by lifting the lower end of the flap on the upper lid while it is inserted into the insertion and locking portion on the lower lid, and the upper lid can be rotated to open. On the other hand, when closing the lid, by pressing the upper lid toward the lower lid, the flap on the upper lid is inserted into the insertion and locking portion on the lower lid, and the locking claw portion on the lower lid fits into the window hole on the flap, easily engaging the upper lid and the lower lid (container body) to lock them.

[0010] In this way, in the container with lid of the present invention, the flap of the top lid is inserted into the insertion locking portion provided on the bottom lid when the lid is closed, making it difficult for children to operate the flap, thereby effectively providing a child lock function. Furthermore, because the flap of the top lid is not exposed to the outside, it is possible to prevent the flap from being operated and opening unexpectedly due to vibrations or impacts during transportation or display, etc. [Brief explanation of the drawings]

[0013] 1 to 6, reference numeral 1 denotes a container with a lid according to the present invention, which is composed of a container body 10 and a lid 20.

[0014] The container body 10 may have any shape as long as it has a rectangular bottom wall 11 and a peripheral wall 12 rising from the edge of the bottom wall 11, with the upper end of the peripheral wall 12 forming an opening 13 and an internal storage space for the contents. The peripheral wall 12 is made up of a front wall 12a, a rear wall 12b, a right side wall 12c, and a left side wall 12d, and is provided with a flange 14 extending horizontally from the upper end to the outside. In this embodiment, the peripheral wall 12 is shown as a rectangular cylindrical shape with a step 15 at its upper portion, but the shape of the container body 10 can be changed as appropriate depending on the application, design, etc., and is not limited to the shape shown in the drawings.

[0015] The container body 10 can be manufactured using a material such as synthetic resin, but the material is not particularly limited. The storage space can store solid contents such as ball-shaped detergents for laundry or dishwashing, cleaning tablets, as well as powder or granular contents.

[0016] 1 to 6, the lid body 20 is composed of an annular lower lid 30 arranged to cover the flange portion 14 of the container body 10 from above, and an upper lid 40 rotatably connected to the lower lid 30 via a hinge 50 provided on the rear wall 12b side of the container body 10. The lid body 20 can be manufactured using a material such as synthetic resin, but the material is not particularly limited. Furthermore, although the lower lid 30 and the upper lid 40 are shown as being integrally molded via the hinge 50 and made of the same material, they may also be made of different materials.

[0017] The bottom cover 30 has an annular top wall 31 located on the upper surface of the flange 14, and an outer wall 32 and an inner wall 33 suspended from both edges of the top wall 31. The bottom cover 30 is fixed to the flange 14 by engaging a plurality of locking claws 38 provided on the inner surface of the outer wall 32 with the underside of the flange 14, or by welding, adhesive, or the like, and there are no particular limitations on the method of attaching the bottom cover 30 to the flange 14.

[0018] The lower lid 30 is provided on the front wall 12a side of the container body 10 with an insertion locking portion 37 consisting of two locking claws 34 that protrude outward and insertion wall portions 36 that are positioned so as to surround the peripheries of the locking claws 34 and form through holes 35 that open vertically. The size of the through holes 35 (insertion wall portions 36) is determined appropriately according to the size of a flap 45 of the upper lid 40 so that the flap 45 can be inserted, as will be described later.

[0019] The upper lid 40 opens and closes the opening 13 of the container body 10, and in the closed state has a top wall portion 41 located above the top wall portion 31 of the lower lid 30 and extending parallel to the top wall portion 31, an outer wall portion 42 suspended from the outer edge of the top wall portion 41 along the outside of the outer wall portion 32 of the lower lid 30, an inner wall portion 43 sloping downward and inward from the inner edge of the top wall portion 41 along the outside of the inner wall portion 33 of the lower lid 30, and a lid portion 44 connected to the inner wall portion 43 and extending approximately parallel to the bottom wall 11.

[0020] The top lid 40 is formed integrally with the bottom lid 30 via a hinge 50 on the rear wall 12b side of the container body 10. The hinge 50 is made of a connecting piece that connects the lower end of the outer wall portion 32 of the bottom lid 30 to the lower end of the outer wall portion 42 of the top lid 40. Although three hinges 50 are provided in this embodiment, the number of hinges 50 is not limited to this, and the hinges 50 may be formed separately from the top lid 40 and the bottom lid 30.

[0021] The top cover 40 has an annular protrusion 48 on the underside of the top wall portion 41, and the protrusion 48 can abut against the top wall portion 31 of the bottom cover 30 to close the opening 13. Note that if it is possible to reliably close the opening 13, the top wall portion 41 of the top cover 40 and the top wall portion 31 of the bottom cover 30 may be in surface contact with each other, in which case the protrusion 48 can be omitted.

[0022] It is also preferable to provide an annular recess 47 between the inner wall portion 43 and the lid portion 44, and when the upper lid 40 is closed, the annular recess 47 fits along the inner wall portion 33 of the lower lid 30 to a position below the inner wall portion 33, thereby tightly closing the opening 13.

[0023] In this embodiment, the lid portion 44 is located closer to the bottom wall 11 than the top wall portion 41, so that a recessed portion is formed by the lid portion 44 and the inner wall portion 43, and by inserting the bottom of the container body 10 of another lidded container 1 into this recessed portion, multiple lidded containers 1 can be stably stacked for storage, display, etc.

[0024] Two flaps 45 formed by a pair of left and right cutouts 49 are provided on the outer wall 42 of the top lid 40 on the front wall 12a side of the container body 10. The two flaps 45 are provided at positions corresponding to the two insertion engagement portions 37 provided on the bottom lid 30, respectively, and have a window hole 46 in the upper central portion. The number of flaps 45 is not particularly limited, but it is preferable to provide them in correspondence with the insertion engagement portions 37 provided on the bottom lid 30.

[0025] In the closed state, the flap 45 is inserted into the through-hole 35 of the lower lid 30, and when opening the lid as described below, the free end 45a of the flap 45 is grasped with the fingers and pulled outward while maintaining the inserted state in the through-hole 35. Therefore, the flap 45 is configured so that the free end 45a extends below the lower end of the outer wall portion 42 and is exposed from below the insertion wall portion 36. Note that the flap 45 may be configured so that the lower end of the free end 45a is not exposed from below the insertion wall portion 36, in which case the child lock effect can be further enhanced.

[0026] The opening and closing operations of the lidded container 1 of this embodiment will be described below. 6(a) is a cross-sectional view showing the closed state, in which pressing the top lid 40 toward the bottom lid 30 causes the flap 45 of the top lid 40 to be inserted into the through-hole 35 in the insertion wall 36 of the bottom lid 30, and the free end 45a at the bottom of the flap 45 descends while elastically deforming outward while abutting against the locking claw 34 (along the locking claw 34), thereby fitting the locking claw 34 into the window hole 46. In this state, even if an attempt is made to rotate the top lid 40 upward, the lower end of the window hole 46 and the locking claw 34 are linked (hooked on), so that the top lid 40 is prevented from rotating upward, and the top lid 40 can be locked.

[0027] In this way, when the lid is closed, the flap 45, which is the starting point for opening the top lid 40, is inserted into the through hole 35 in the insertion wall portion 36, as described below, making it difficult for children to tamper with it and open it, and since the flap 45 is not exposed to the outside, it is possible to prevent the flap 45 from being accidentally operated due to vibrations or impacts during transportation or display, etc.

[0028] To open the lid, as shown in Figure 6(b), the free end 45a of the flap 45 is grasped and pulled outward while it is inserted into the through-hole 35. This releases the connection between the window hole 46 of the flap 45 and the locking claw 34. Note that by making the flap 45 an elastic piece, it can be pulled outward and elastically deformed and restored along the locking claw 34, allowing repeated opening and closing operations.

[0029] When the connection between the window hole 46 of the flap 45 and the locking claw portion 34 is released, and the flap 45 is lifted upward as shown in Figure 6(c), the top cover 40 rotates via the hinge 50, and the top cover 40 can be opened by removing the flap 45 from above the through hole 35. [Industrial Applicability]

[0030] The lidded container of the present invention can be suitably used as a container that requires a child lock function for detergents, medicines, etc. [Explanation of symbols]
