Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an inner lid holding structure for holding an inner lid on a container having an open top, such as a container made of synthetic wood.

[Conventional technology]

Conventionally, the holding structure for the inner lid 4 of the container 1 is as shown in FIG. A hole 3 is formed, and projections 25 on both side edges are inserted into the inner lid holding hole 3 to hold the inner lid 4 at a desired depth of the container 1. When opening the inner lid 4, the inner lid 4 is moved to one side, the protrusion 25 on the other side is removed from the inner lid holding hole 3, and the inner lid 4 is lifted diagonally and removed.

[Problem that the invention attempts to solve]

The holding structure of the inner lid of the conventional container was constructed as described above, and although the inner lid 4 could be easily opened and closed, it could be damaged by the contents hitting the inner lid 4 or by vibrations during handling. There was also a problem in that the inner lid 4 moved to one side and came off. There was also the problem that the inner lid 4 moved and made rattling noises during transportation.

[Structure of the idea]

The holding structure for the inner lid of the container of the present invention is formed by forming inner lid holding holes 3 facing each other at vertical intervals in opposing side walls 2, 2 of a box-shaped container 1 which is open at the top. A protrusion 25 is provided on one side edge, and a lock body 26 is attached to the other side edge of the inner cover 4 so as to be slidable in a direction perpendicular to the edge of the inner cover 4. Lock protrusion 5 formed at the tip of
The lock 26 is biased by the elastic body 6 so that the lock protrusion 5 elastically protrudes from the edge of the inner lid 4. The lock body 26 is provided with a handle portion 13, and one side wall 2 It is characterized in that a protrusion 25 is fitted into the inner lid holding hole 3 and a locking protrusion 5 is inserted into the inner lid holding hole 3 of the other side wall 2.

[Effect]

In the present invention, a protrusion 25 is formed at one end of the inner lid 4, a locking protrusion 5 is elastically protruded from the other end, and the locking protrusion 5 elastically protrudes. The inner lid 4 can be held on the container 1 with the inner lid 4 pushed to one side, and the contents may hit the inner lid 4 or the inner lid 4 may be damaged due to vibration during transportation or handling. It does not move to one side, the inner lid 4 does not open unexpectedly, and the locking protrusion 5
is inserted into the inner lid holding hole 3, so that rattling noise of the inner lid 4 can be prevented, and all that is required is to hook the hand on the handle part 13 and retract the locking protrusion 5. This allows the inner lid 4 to be opened easily.

【Example】

The container 1 is formed into a box shape with an open top, and may be integrally molded from synthetic resin or may be foldable as shown in FIG. In this folding type, the lower ends of four side plates 15 are rotatably attached to the four circumferences of the bottom plate 14 by threaded parts (not shown), and the four side plates 15 surround the top of the bottom plate 14. The side walls 2 are configured, and each side plate 15 is connected to the bottom plate 14.
It can be folded compactly by folding it over the top. When assembled in a box shape,
Adjacent side plates 15 are connected to each other by a fitting protrusion and a fitting recess. Among the side plates 15, a large number of inner lid holding holes 3 are formed in the side plates 15a, 15a which are opposite to each other in the longitudinal direction of the container 1 at vertical intervals, and the opposite side plates 1 are formed.
5a and 15a have inner lid holding holes 3 facing each other while maintaining a substantially horizontal level. The inner lid holding hole 3 is composed of a pair of through holes 3a, 3a spaced apart in the horizontal direction, but the number and shape thereof can be changed.
Moreover, it is not necessary to penetrate the hole. The inner lid 4 is formed into a plate shape large enough to close the opening of the container 1, and has a pair of projections 25, 25 integrally formed at one longitudinal end thereof. The distance between these protrusions 25, 25 is made equal to the horizontal distance between the through holes 3a, 3a. On the back surface of the other end of the inner lid 4, a lock housing part 19 for housing the lock body 26 is formed as shown in FIG. A lock body 26 having a protrusion 5 at its tip is slidably housed, and the lock body 26 can be slid in a direction perpendicular to the edge of the inner lid 4.
6 is elastically biased by an elastic body 6 so that its locking protrusion 5 protrudes from the edge of the inner lid 4, as shown in FIGS. 4a and 4b. That is, a rubber band-like elastic body 6 is installed between ribs 20 that protrude from the back surface of the lock protrusion storage part 19, and a hook pin 21 that protrudes from the upper surface of the lock body 26 is attached as shown in FIG. 4b. As shown in the figure, the lock body 26 is urged to protrude by being hooked onto the elastic body 6, and the lower surface of the lock body 26 is pressed by the claw pieces 24 protruding from both sides of the lock body housing portion 19 of the inner lid 4. At the same time, the small protrusion 23 protruding from the lower surface of the lock body 26 comes into contact with the claw piece 24, and the lock body 26
is prevented from falling out. The distance between the pair of lock protrusions 5, 5 formed on the lock body 26 is also made equal to the horizontal distance between the through holes 3a, 3a serving as the inner lid holding hole 3. Notches 7 are formed at both ends in the longitudinal direction of the inner lid 4, and cutout portions 8 approximately equal to the notches 7 are formed in the lock body 26, so that the lock body 26 is made of an elastic material. When the locking protrusion 5 is urged to protrude by the lock member 6 and protrudes from the inner lid 4, the tip portion 13 of the cutout 8 of the lock body 26
a protrudes into the notch 7 of the inner lid 4, and the tip portion 13a of the cutout 8 that protrudes into the notch 7 in this way serves as a handle part 13. By pushing and pushing the handle part 13 through the elastic body 6 and into the notch 8, the lock body 26 can be retired inwardly into the inner lid 4, and the lock protrusion 5 can be retired from the inner lid 4. I have made it possible. The container 1 is used to store and transport the product, and when the product is small, the inner lid 4 is held at the height of the stored product to hold the product well and handle it without rattling it. It is something.

[Effect of the idea]

As described above, the present invention has a protrusion protruding from one edge of the inner lid, and a lock body is attached to the other end of the inner lid so that it can slide freely in a direction perpendicular to the edge of the inner lid. A locking protrusion formed at the tip of the lock body protrudes from the edge and can be freely retired, and the lock body is urged by an elastic body to elastically protrude from the edge of the inner lid, and one side wall Since a protrusion is inserted into the inner lid holding hole and a locking projection is inserted into the inner lid holding hole on the other side wall, the elastically protruding locking projection prevents the inner lid from rattling. This prevents the contents from hitting the inner lid, preventing the inner lid from shifting to one side due to vibrations during transportation or handling, and preventing the inner lid from opening unexpectedly. Moreover, since the locking protrusion is inserted into the inner lid holding hole, rattling noise of the inner cover can be prevented. It has the advantage that the inner lid can be opened easily by simply pulling it back.
