[0013]
The container 10 is a container for storing contents such as wet paper impregnated with a liquid (for example, water or a chemical solution) according to the purpose of use, and has a container body 11 and a lid 12 as shown in FIGS. are doing.
[0014]
The container body 11 has a box 13 capable of storing contents such as wet paper, and an inner lid 14 fitted to the upper edge of the box 13. Then, the container body 11 forms a through hole 16 as an opening in a seal ring 15 provided on a top surface portion 14A of the inner lid 14, and the contents in the box 13 can be taken out from the through hole 16. I have. In the inner lid 14, the entire top surface portion 14A and side surface portions 14B are made of flexible plastic.
[0015]
The lid 12 is rotatably joined to a top surface portion 14A of the inner lid 14 constituting the container main body 11 via a hinge 20, and covers the opening 16 of the container main body 11.
[0016]
The lid 12 has an inner ring 21 and an outer ring 22 on its inner surface. When the lid 12 is closed, the inner ring 21 is fitted to the seal ring 15 of the inner lid 14 so that the opening 16 can be sealed. The outer ring 22 can be abutted against the top surface 14A of the inner lid 14. The sealing of the opening 16 keeps the contents of the container body 11 wet.
[0017]
The hinge 20 is an indirect joint hinge configured by loosely fitting a pair of hinge pins 20A provided on the lid 12 into a pair of hinge holes 20B provided on the top surface portion 14A of the inner lid 14. In the present embodiment, the lid 12 and the inner lid 14 are provided separately, and both are joined by the hinge 20. However, the lid 12 may be formed integrally with the inner lid 14 including the bent hinge 20.
[0018]
A rubber-like elastic body 30 is disposed near the top surface 14A of the inner lid 14 and the hinge 20 of the lid 12, which constitute the container body 11. When the lid 12 is closed, the rubber-like elastic body 30 is elastically deformed between the inner lid 14 and the lid 12, and the elastic restoring force allows the lid 12 to be fully opened.
[0019]
The rubber-like elastic body 30 has an L-shape in which one end and the other end cross each other at right angles and are integrated (FIG. 5), and one end is fitted into a fitting recess 31 provided on the back surface of the lid 12. The other end is set to contact the top surface 14A of the inner lid 14 with the lid 12 fully opened.
[0020]
The rubber-like elastic body 30 is made of rubber or an elastomer (for example, a methylvinyl-based raw rubber synthesized with Shin-Etsu Chemical KE951U as a compound and C-8 as a vulcanizing agent).
[0021]
A locking recess 41 is provided on the outer surface of the inner lid 14 constituting the container body 11 on the side opposite to the hinge 20 of the seal ring 15, and the locking recess is provided on the inner surface of the inner ring 21 of the lid 12 when the lid is closed. A locking projection 43 is provided for locking to 41. The locking concave portion 41 and the locking convex portion 43 form a locking mechanism and lock each other when the lid 12 is closed, and close the lid 12 against the elastic restoring force of the rubber-like elastic body 30 in the closed position. To keep.
[0022]
The locking action of the locking concave portion 41 on the inner lid 14 side and the locking convex portion 43 on the lid 12 side is caused by the pressing of the top surface portion 14A of the inner lid 14 constituting the container body 11 due to the pressing of the seal ring 15. It is released by bending deformation. That is, when the top surface portion 14A of the inner lid 14 is pressed by the pressing force F, the seal ring 15 connected to the top surface portion 14A undergoes bending deformation, whereby the seal ring 15 warps inward of the box, and the seal ring 15 The locking concave portion 41 comes off the locking convex portion 43 of the lid 12.
[0023]
Embosses 50A and 50B are integrally formed on the top surface 14A of the inner lid 14 constituting the container main body 11 on both sides of a portion where the lid 12 is attached, as pressing designation portions. The embosses 50A and 50B are provided at positions where the pressing deformation of the top surface portion 14A can be most easily transmitted to the locking concave portion 41 of the seal ring 15.
[0024]
Further, the container 10 forms a protruding stopper 51 around the hinge 20 on the top surface 14A of the inner lid 14 constituting the container body 11, and forms an engaging portion 52 around the hinge 20 on the lid 12. Then, when the lid is opened, the engagement portion 52 is brought into contact with the stopper 51 to determine the full opening angle of the lid 12 around the hinge 20 (FIGS. 2 and 5).
[0025]
At this time, in the container 10, as shown in FIGS. 4 and 5, a rib 53 is provided on the back surface of the lid 12 around the hinge 20, and the back surface near the hinge 20 of the lid 12 is provided for the elastic body 30. In addition to the fitting concave portion 31, the protruding outer edge of the lid 12 around the hinge 20 is the engaging portion 52, and an auxiliary rib 54 connected to the rib 53 is provided on the back surface of the lid 12 near the engaging portion 52. I'm supposed to. As shown in FIGS. 4 and 5, a concave portion 55 defined by a reinforcing rib 54 is formed on the back side of the engaging portion 52 in the lid 12. The concave portion 55 moves around the stopper 51 of the inner lid 14 when the lid is opened, and brings the engaging portion 52 of the lid 12 into contact with the stopper 51.
[0026]
Therefore, the container 10 is used as follows.
When the lid 12 is closed, the rubber-like elastic body 30 elastically deformed with the closing of the lid 12 by the locking action between the locking concave portion 41 on the inner lid 14 side and the locking convex portion 43 on the lid 12 side. The closed state of the lid 12 is maintained against the elastic restoring force (FIG. 3).
[0027]
When the embosses 50A and 50B of the inner lid 14 are pressed when the lid 12 is opened, the locking action between the locking recess 41 on the inner lid 14 and the locking projection 43 on the lid 12 is released as described above. Is done. Thereby, the elastic restoring force of the rubber-like elastic body 30 pushes the inner surface of the lid 12, and the lid 12 is opened until it is fully opened (FIG. 2). The full opening angle of the lid 12 is determined by the engagement of the engaging portion 52 of the lid 12 with the stopper 51 of the inner lid 14.
[0028]
Hereinafter, the operation and effect of the present embodiment will be described.
{Circle around (1)} When the flexible top surface 14A of the container body 11 is pressed in a closed state of the lid 12 in which the elastic restoring force of the rubber-like elastic body 30 acts on the lid 12, a side surface connected to the top surface 14A. Since the locking action of the locking mechanism (the locking concave portion 41 on the inner lid 14 and the locking convex portion 43 on the lid 12) is released by the bending deformation of the portion 14B and the like, the rubber-like elasticity The lid 12 is fully opened by the elastic restoring force of the body 30, and the opening 16 of the top surface portion 14A is opened. For this reason, the lid 12 can be immediately fully opened just by placing the container 10 on the floor or on a desk or the like and pressing the top surface 14A of the container body 11 with one hand, and the opening 16 of the top surface 14A can be immediately opened with one hand. The contents of the container body 11 can be taken out from the container.
[0029]
{Circle around (2)} When the lid 12 is fully opened due to the elastic restoring force of the elastic body 30 as in the above [1], the engaging portion 52 of the lid 12 abuts against the stopper 51 of the container body 11, and the full opening angle of the lid 12 is reduced. It is restricted to a predetermined angle.
[0030]
(3) The elastic restoring force of the elastic body 30 acting on the lid 12 when the lid 12 is closed is a force for deforming the lid 12. That is, the elastic restoring force of the elastic body 30 tends to cause a concave deformation (FIG. 6) in which the portion of the lid 12 around the hinge 20 is pushed inward of the lid. When this concave deformation occurs, (a) the lid 12 is strongly pressed by the opening 16 of the container body 11 so that the lid cannot be opened due to its elastic restoring force, or (b) the engaging portion 52 of the lid 12 It warps in the direction away from the stopper 51 of the main body 11, and impairs the action of restricting the full opening angle of the lid due to the abutment between the engaging portion 52 of the lid 12 and the stopper 51 of the container main body 11 in (2). However, in the present invention, the ribs 53 and the reinforcing ribs 54 provided on the back surface of the lid 12 increase the rigidity of the lid 12 and prevent the above-mentioned concave deformation of the lid, so that the above (a) and (b) are reliably avoided. However, the lid 12 can be fully opened immediately and at a predetermined angle.
[0031]
As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration of the present invention is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. Included in the present invention. For example, when the container body is composed of the box 13 and the inner lid 14, the lid 12 may be joined to the box 13 via a hinge.
[0032]
Further, another elastic body may be used instead of the rubber-like elastic body. However, since the rubber-like elastic body is not made of a metal such as a leaf spring, it does not corrode, and therefore, rust does not enter the contents in the container body. Further, since the restoring force of the rubber-like elastic body is not excessive as in the case of a leaf spring or the like, the lid can be opened slowly at an appropriate speed.
[0033]
【The invention's effect】
As described above, according to the present invention, it is possible to obtain a container in which the lid can be opened immediately and at a predetermined full opening angle only by using one hand.
