Description

[Detailed description of the invention] The present invention relates to container lids, and more specifically, it prevents the lids from blocking each other or falling over when a large number of lids are stacked, so that they can be aligned stably. The present invention relates to a lid that can be easily loaded into a filling machine.

Conventionally, container lids are stacked and loaded into a filling machine and automatically placed on the container body, and are provided with rims or ribs to prevent them from fitting into each other. However, such conventional lids have a concave central part to provide a rim or ribs, etc.
Therefore, it is difficult to adhere to a container whose opening is made horizontal with a sealant, etc., and a space is provided between the lid and the sealant so that secondary items such as sugar and spoons can be stored. Lids with convex centers tend to block each other, and when a large number of lids are stacked and arranged, they become unstable and fall over.

The inventor of the present invention solved this inconvenience by allowing sub-storage items to be stored between the sealing material at the mouth of the container main body, so that when a large number of items are stacked, they fit together and can be aligned without falling over, allowing them to be stably inserted into the filling machine. As a result of research to develop a lid that can be loaded, it was found that in a lid for a container that has a diagonal side wall around the top plate and an outer peripheral wall around the diagonal side wall via a horizontal plate, a protrusion pointing inward on the outer peripheral wall. It has been discovered that the above-mentioned drawbacks can be overcome by providing an outward protrusion on the diagonal side wall and providing a plurality of ribs that protrude from the diagonal side wall and substantially hang down on the horizontal plate, and based on this knowledge, Based on this, the present invention was completed.

That is, the gist of the present invention is to provide a diagonal side wall around the top plate, provide an outer circumferential wall around the diagonal side wall via a horizontal plate, provide an inward protrusion on the outer circumferential wall, and provide an outer peripheral wall on the oblique side wall. This container lid is provided with a protruding portion facing toward the side, and a plurality of ribs protruding from the oblique side wall and substantially hanging down on a horizontal plate.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 3 show embodiments of the lid of the present invention, in which FIG. 1 is a partially sectional plan view, FIG. 2 is a side view, and FIG. The sectional view and FIG. 4 are partial perspective views.

To explain the present invention using drawings, a diagonal side wall 7 is formed downwardly around the top plate 8, and the center of the diagonal side wall 7 has a convex center where an outer peripheral wall 9 is provided with a horizontal plate 6 interposed therebetween. This is the lid 1 that has become shaped. Diagonal side wall 7
has a partially outwardly directed protrusion 5 at an arbitrary position.
A horizontal plate 6 in which a plurality of ribs 3 are formed between the protruding parts 5 and connect the oblique side wall 7 and the outer peripheral wall 9.
It is substantially suspended upwardly from the oblique side wall 7 toward the outer circumferential wall 9 . The outer circumferential wall 9 is formed with an inward protrusion 4 and a skirt 2. Inwardly directed protrusions 4 are provided all around or partially so that they can be fitted into the container body.

When the lids 1 are stacked on top of each other, blocking is prevented by the partially provided outward protrusions 5 and the inward protrusions 4 formed on the outer peripheral wall 9 as shown in FIGS. 5 and 7. However, if a lateral force W is applied when a large number of stacked stacks are applied, the stacks will become unstable due to the lack of supporting parts and will slide sideways, resulting in the stack falling over as shown in Figure 6. To prevent this, the inclined side wall 7
A rib 3 is provided which substantially hangs down from the horizontal plate 6 toward the outer peripheral wall 9. By providing this rib 3, the front walls b come into contact with each other as shown in the 8th figure, and the side walls a and a' of the rib 3 fit into the side walls a and a' of the rib 3 of the other lid as shown in the 9th figure. By pressing against each other, even when a lateral force W is applied, they do not slide sideways, and can be stably aligned and stacked without falling over.

FIG. 10 shows another embodiment of the lid of the present invention,
The shape of the lid is square.

FIG. 11 shows yet another embodiment of the lid of the present invention, in which the lid has a hexagonal shape.

FIG. 12 shows yet another embodiment of the lid of the present invention, in which the lid has a triangular shape.

As described above, the shape of the lid of the present invention is not limited to a round shape, and may be any shape such as a square, hexagon, or triangle. FIG. 13 shows other rib shapes.

Since the lid of the present invention having the above-mentioned structure is stably aligned when stacked in large numbers, it is easy to load it into a filling machine, and it is possible to fit it to the container body using an automatic machine. Furthermore, since the central portion protrudes, there is a space between the mouth sealing material surface and a sub-storage item can be stored in this space.
