Description

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

The present invention relates to an inner lid of a container.

[Conventional technology]

Conventionally, various containers have been used for transporting and transporting goods. However, a container is generally a one-piece plastic molded product and does not have a structure in which the depth can be adjusted according to the size of the items stored therein. For this reason, when an article smaller than the size of the container is stored, there is a problem in that the article bounces up inside the container due to vibrations during transportation and may be damaged. Therefore, Japanese Utility Model Publication No. 58-46022 discloses a container in which an inner lid is provided inside the container so that the height of the inner lid can be adjusted depending on the size of the article. The inner lid of this conventional container has protrusions integrally protruding from its periphery, and is flexible enough to be bent by hand. The structure was such that the inner lid was fitted into the hole in the container and the inner lid was installed inside the container body.

[Problem that the invention attempts to solve]

Conventional inner lids of containers have the structure described above, so when attaching the inner lid to the container body, after storing the item inside the container body, apply force to the inner lid to bend it. The inner lid is attached to the container body by fitting the protrusion into the hole in the container body. Conversely, when removing the inner lid from the container body, the inner lid must be bent and removed from the container body. It was difficult to put on and take off the lid. In addition, since the inner lid needs to be bent when it is attached or removed, it is not possible to use a rigid inner lid.
The function of the inner lid is only to hold down the stored items, and it has not been possible to partition the inside of the container so that items can also be stored on the inner lid. Therefore, regarding the conventional inner lid of a container, it is necessary to make it easy to attach and detach from the container body, and also to make it easier to attach and detach from the container body when the inner lid is made rigid. This is a subject to be addressed.

[Means to solve the problem]

In the container inner lid of the present invention, an elongated hole 22 is bored in the inner lid main body 1, and the legs 24 protruding from the lower surface of the slide block 2 are inserted into the elongated hole 22, so that the slide block 2 is inserted into the inner lid main body 1. It is slidably attached, and by sliding the slide block 2, the locking part 3 at the tip of the slide block 2 is attached to the inner lid main body 1.
A split groove 31 is cut into the longitudinal edge of the elongated hole 22, and a concave or convex fitting part 32 is provided on the side surface of the slide block 2, so that when the locking part 3 is in the protruding state, A fitted portion 33 capable of fitting with the fitting portion 32 is provided on the inner lid main body 1, and locking holes 6 are provided on the inner surface of the peripheral wall portion 5 of the container main body 4 at appropriate intervals in the height direction. It is installed in the container body 4 by engaging the locking part 3 with either of them.

[Effect]

In the inner lid of the container of the present invention, as described above, the locking part 3 of the slide block 2 is connected to the container body 4.
The inner lid is locked into the locking hole 6 of the container body 4.
By sliding the slide block 2, the locking part 3 can be locked in the locking hole 6 of the container body 4, so the inner lid can be attached like a conventional inner lid. There is no need to bend the inner lid, and the inner lid can be easily installed inside the container body 4. Furthermore, since there is no need to bend the inner lid, the inner lid can be made rigid and items can be placed on the inner lid. Furthermore, slide block 2
A concave or convex fitting part 32 is provided on the side surface of the inner lid main body 1, and a fitted part 3 that can be fitted to the fitting part 32 is provided on the side of the inner lid main body 1.
3, the fitting part 32 and the fitted part 33 are provided.
By fitting these together, the locking portion 3 of the slide block 2 can be locked to prevent it from being inadvertently retracted. Moreover, since a split groove 31 is cut into the edge of the elongated hole 22, the split groove 31 widens when the slide block 2 slides, thereby smoothing the engagement and disengagement between the fitting part 32 and the fitted part 33. In addition, the fitting force between the fitting part 32 and the fitted part 33 can be increased.

【Example】

The container A consists of a container body 4, an inner lid 7, and an outer lid 8. The container body 4 is
It has a tapered peripheral wall portion 5, which is wide at the top opening side and narrow at the bottom side. Thus, the container bodies 4 can be stacked such that the lower part of the upper container body 4 is fitted into the upper part of the lower container body 4. On the outer surface of both long side walls 12 of the peripheral wall portion 5, a pair of vertical plate-shaped leg ribs 11 extending from below the flange 13 to the center of the long side wall 12 are provided. A pair of box-shaped box ribs 15 extending to the center of the short side wall 14 are protruded, and when the container bodies 4 are stacked on top of each other, the leg ribs 11 and the box ribs 15 of the upper container body 4
The lower surface of the container body 4 rests on the upper surface of the flange 13 of the lower container body 4, thereby keeping the upper container body 4 horizontal and preventing the container bodies 4 from fitting tightly together. Further, a recess 9 is formed in both corners of the inner surface of the short side wall 14 over the entire length in the vertical direction, and corresponding to the recess 9, a protruding rib is provided on both sides of the outer surface of the short side wall 14 over the entire length in the vertical direction. 10 is formed, and when the container bodies 4 are stacked up and down, the projecting ribs 10 slide and fit into the recesses 9. Furthermore, the short side wall 14
A plurality of locking holes 6 are bored in the upper part of the inner surface adjacent to the recess 9 in a plurality of upper and lower stages. In Figure 3, box rib 1
Although a plurality of partition pieces 17 are horizontally extended from the inner surface of the partition plate 5 to form a locking hole 6 between the partition pieces 17, the locking hole 6 is not limited to this structure. A perforated plate with stop holes 6 formed therein may be attached to the front surface of the box rib 15 by heat welding or the like. The inner lid 7 has such rigidity that it does not easily bend, and has external dimensions that allow it to be stored up to about 1/2 the depth inside the container body 4. An outer peripheral edge part 20 having an inverted U-shaped cross section is provided around the edge of the inner lid main body 1, and an outer peripheral edge part 20 surrounded by the outer peripheral edge part 20 and a jetty part 18 is provided on both longitudinal edges of the inner lid main body 1. A pair of recesses 19 are formed. Jetty part 18
extend from the inner surface of the outer peripheral edge portion 20 in a substantially L-shape so as to face each other, and the tip surfaces of the jetty portions 18 are separated from each other, but are opposed to each other with a gap in between. In addition, a window 21 is opened in the outer peripheral edge 20 in the recess 19.
A pair of parallel elongated holes 22 are bored in the bottom of 9. On the other hand, as shown in FIG. 1, the slide block 2 is provided with an operating rib 23 on the upper surface of its base end for hooking a finger, and a pair of rod-shaped legs 24 protruding from the lower surface of its base end. A truncated conical fitting protrusion 34 is provided at the lower end of the leg 24. Fixed piece 25 connected to slide block 2
has a pair of protrusions 35 with a diameter equal to the width of the long hole 22.
are provided protrudingly, and each protrusion 35 has a leg portion 24.
Fitting holes 26 are bored at the same intervals as the two.
The fixing piece 25 has a protrusion 35 disposed on the lower surface of the inner lid body 1 and slidably fitted into the elongated hole 22. Fitted into the fitting piece 26,
The slide block 2 and the fixed piece 25 are integrated. Therefore, the slide block 2 can be slid by grasping the operating rib 23 with your fingers and moving it back and forth. Since it is inserted into the window 21, when the slide block 2 is slid, the locking part 3 is inserted into the inner lid 7.
protruding or retracting from the edge of the Further, as shown in FIG. 2, a split groove 31 is cut in the rear end edge of the elongated hole 22 at a position near the fitted portion 33, and when force is applied by the split groove 31, the elongated hole 22 is slightly opened in the width direction. Further, a convex fitted portion 33 is provided on the inner surface of the jetty portion 18 near the rear end of the elongated hole 22, and locking portions 3 are provided on both sides of the slide block 2.
A recessed fitting part 32 is provided at a position corresponding to the fitted part 33 when the locking part 3 is protruded and a position corresponding to the fitted part 33 when the locking part 3 is retracted. With the locking part 3 retracted, the inner lid 7 is moved to the container main body 4 as shown in FIG. 5 or 6.
The inner lid 7 is delivered by sliding the four slide blocks 2 to protrude the locking parts 3, and inserting and locking each locking part 3 into the locking hole 6 of an appropriate height. can be held horizontally within the container body 4. The height of the inner lid 7 can be adjusted by selecting the locking hole 6 with which the locking portion 3 is engaged. Conversely, by sliding the slide block 2 and removing the locking portion 3 from the locking hole 6, the inner lid 7 can be easily taken out from the container body 4. In addition, when the locking portion 3 is protruded, the fitting portion 32 of the slide block 2 is fitted into the fitted portion 33 of the jetty portion 18 and locked, so that the locking portion 3 inserted into the locking hole 6 is locked. The inner lid 7 will not come off from the container body 4 due to the stop part 3 being inadvertently drawn. On the contrary, even when the locking part 3 is retracted, the fitting part 32 is locked by being locked with the fitted part 33, so the locking part 3 does not pop out without permission.
It is easy to use. Moreover, since the split groove 31 is cut into the edge of the elongated hole 22, the split groove 31 widens to allow the fitted portion 33 to easily move back in the lateral direction. This makes it possible to reduce the force required to engage and disengage the joint portion 33, thereby making engagement and disengagement smooth. Furthermore, the fitting part 3
Since the engagement and disengagement between the fitting part 2 and the fitted part 33 can be made smooth, it is possible to increase the unevenness of the fitting part 32 and the fitted part 33, and the fitting when they are fitted can be made smoother. The engagement force between the portion 32 and the fitted portion 33 can be increased. In addition, a handle may be provided on the upper surface of the inner lid 7 to facilitate the insertion and removal of the inner lid 7. As shown in FIG. 4, the outer lid 8 has a structure in which the outer peripheral portion 27 is placed on the flange 13 of the container body 4, and there are holes at the center of both longitudinal ends.
A slide block 2 having the same structure as the slide block 2 of the inner lid 7 (the dimensions and dimension ratio may be different).
is attached so that it can slide freely, and by sliding the slide block 2, the locking part 3
can be made to protrude from a through hole 28 bored in the base of the outer circumferential part 27 to the lower surface of the outer circumferential part 27. On the other hand, an insertion hole 29 is bored in the upper end of the inner surface of the container main body 4 so as to face the through hole 28 of the outer cover 8, and the locking part 3 is inserted into the insertion hole 29 by sliding the slide block 2. By doing so, it is possible to prevent the outer lid 8 from coming off from the container body 4. After the articles are stored in the container body 4, the inner lid 7 is inserted into the container body 4, and the inner lid 7 is fixed at an appropriate height depending on the size of the article. Container A can be used with only the inner lid 7 attached like this, or by placing more items on top of the inner lid 7 and then placing the outer lid 8 on top of the container body 4. It is also possible to do so. With the outer lid 8 attached, another container A can be placed on the outer lid 8 as shown in FIG. Furthermore, empty containers A and the like can be stacked in a relatively low-volume state by fitting the container bodies 4 together as shown in FIG. The one shown in FIG. 10 is another example of the present invention, in which a split groove 31 is provided in the center of the longitudinal edge of the elongated hole 22, and the position of the split groove 31 is located at the engaged portion 33.
, the split groove 34 is likely to open when force is applied to the engaged portion 33.

[Effect of the idea]

As described above, the present invention allows the inner lid to be installed inside the container body by locking the locking part of the slide block into the locking hole of the container body, and the locking part can be attached by sliding the slide block. Since the inner lid can be locked in the locking hole of the container body, there is no need to bend the inner lid unlike conventional inner lids, and the inner lid can be easily installed inside the container body. Furthermore,
Since there is no need to bend the inner lid, the inner lid can be made rigid and items can be placed on the inner lid. Furthermore, a concave or convex fitting part is provided on the side surface of the slide block, and a fitted part that can be fitted with the fitting part is provided on the side of the inner lid main body, so that the fitting part and the fitted part are separated. By fitting these together, the locking portion of the slide block can be locked to prevent it from being inadvertently retracted. Moreover, since a split groove is cut into the edge of the elongated hole, the split groove widens when the slide block slides, making it possible to smoothly engage and disengage the mating part and the mated part. It is possible to increase the fitting force between the part and the part to be fitted.
