Description

[Detailed description of the invention] The present invention relates to a container with a lid, and in particular increases the strength of the lid formed from a foamed synthetic resin sheet, and at the same time provides a drainage function to the lid itself, improving the adhesion between the container and the lid. This is an improved version.

In recent years, it has been used as a container for storing and transporting fresh fish.
Products made of foamed synthetic resin are widely used because they have excellent lightness, heat insulation, and moldability.If the lid of the container is made of foamed synthetic resin sheet, it may sag due to lack of rigidity. It is easy for the center part of the lid to sag due to rainwater that accumulates on the lid, which greatly spoils the appearance. Further, when the lid is removed from the container, there is a problem in that sewage collected on the lid flows into the container.

Therefore, the present invention has developed a lid made of a foamed synthetic resin sheet that has a joining edge large enough to overlap with the upper edge of the container body, and by recessing a part of the lid, an endless line along the joining edge is created. A shaped water collection groove and a plurality of drainage grooves communicating with the water collection groove are provided respectively, and these grooves increase the strength and at the same time exhibit the drainage function. To provide a container with a lid configured to improve adhesion to the container.

That is, the container with a lid, which is a feature of the present invention, has a lid attached to the container body made of an elastic foamed synthetic resin sheet, and the peripheral portion of the lid is large enough to overlap with the upper edge of the container body. At the same time, the lid body is provided with an endless water collection groove adjacent to the joint edge, and the water collection groove includes a drainage groove provided in the middle part of the lid body. and a drain port provided on the joining edge, respectively, and the drain port is fitted into a fitting portion provided on the upper edge of the container body.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First Embodiment In FIGS. 1 to 3, reference numeral 1 denotes a relatively thick container body made of foamed synthetic resin (e.g. foamed polystyrene), the upper edge 1a of which has a partially convex step. 2 is a lid attached to the container body 1. The lid body 2 is made of a foamed synthetic resin sheet (for example, a foamed polystyrene sheet),
The apparent width of the surrounding area is 1 at the upper edge of the container body 1.
The inner half of the joining edge 3 is formed into a fitting recess 3a that can fit into the convex portion of the upper edge 1a. Fitting recess 3a
is provided with a discharge port 4 that communicates with a water collection groove described later, and a convex portion of the upper edge 1a of the container body 1 corresponding to this drain port 4 is cut out, and the portion of the discharge port 4 is fitted. It is formed in a fitting part that fits together.

The lid body 2 is provided with an endless water collection groove 5 adjacent to the fitting recess 3a.
A plurality of drainage grooves 6 provided in the middle portion of the lid body 2 communicate with each other at both end portions, and 7 is the communication portion. Then, the fitting recess 3a and the water collection groove 5
The drainage groove section 6 is provided by shaping a part of the lid body 2 into an uneven shape.

According to the first embodiment, not only the strength of the lid 2 is increased by the fitting recess 3a, the water collection groove 5, and the drainage groove 6, but also waste water such as rainwater that accumulates on the lid 2 can be removed. The water flows out through the drainage groove 6, the water collection groove 5, and the outlet 4. Therefore, when the lid body 2 is attached to the container body 1, the fitting recess 3a of the joint edge 3 fits into the convex part of the upper edge 1a, so that the attachment state is tight due to the elasticity of the lid body 2. Become a thing,
There is no need to worry about rainwater or the like flowing into the container body 1. The bottom portion 1b of the container body 1 is formed into a slightly convex shape in order to ensure stability when the containers are stacked together.

Second Embodiment In FIGS. 4 to 6, a container body 11 and a lid body 1
The material of 2 is the same as that of the first embodiment,
A fitting portion 11b is provided in the upper edge 11a of the container body 11 by a notch. On the other hand, the peripheral part of the lid body 12 is formed with a joining edge 13 having the same width as the upper edge 11a of the container body 11, and this joining edge 13 has a recessed part corresponding to the fitting part 11b. A drain port 14 is provided. Fitting part 11b and drain port 14
The bottom portion of the container body 11 is formed into an inclined surface portion slanting outward, and when the lid body 12 is attached to the container body 11, the drain port 14 is fitted into the fitting portion 11b.

The lid body 12 is provided with an endless water collection groove 15 adjacent to the joint edge 13.
5 has a drainage groove 1 provided in the middle part of the lid body 12.
6a and 16b are in communication 17 at both end portions. The drainage grooves 16a and 16b intersect in a criss-cross pattern, and the bottoms thereof are formed to have a flow gradient from the intersecting center toward both tips to promote drainage. In the illustrated case, a water passage groove 1 is further parallel to the water collection groove 15.
8 is provided in an endless shape, and the water collection groove 15 and the drainage grooves 16a, 16 are connected to each other through the water passage groove 18.
It communicates with b. 19 is a communication port provided between the water collection groove 15 and the water passage groove 18; when the water passage groove 18 is not provided, the drainage groove 16a,
Each tip of 16b is directly connected to the water collection groove 15. Note that each of the grooves 15, 16a, 16b, 1
8 is formed by shaping a part of the lid 12 into an uneven shape as in the first embodiment, and the bottom 11c of the container body 11 is formed into a slightly convex shape, thereby making the lid 12 uneven. Stability can be ensured when the containers 11 having the coating 12 attached thereto are stacked on top of each other.

According to this second embodiment, not only the strength of the lid 12 is increased by the water collection groove 15 and the drainage grooves 16a, 16b, etc., but also the lid 12 is attached onto the container body 11. At this time, the outer wall portion of the water collection groove 15 comes into contact with the inner surface of the container body 11 (see Fig. 5), and the adhered state is due to the strong elasticity of the lid body 12 due to the uneven structure formed by the groove. Therefore, it becomes a tight structure, and also the discharge port 14 and the water collection groove 1
5. Drainage grooves 16a, 16b, water flow grooves 18
The drainage action is also promoted, and rainwater etc.
It is possible to completely prevent problems such as when the lid body 12 is bent due to accumulation in the central part of the lid body.

Although the present invention is as described above, even though the lid is made of a foamed synthetic resin sheet, it can maintain sufficient strength, while rainwater that collects on the lid is drained from the center of the lid. Since the water is collected from the provided drainage groove into the water collection groove and can be discharged through the drain port, the lid is prevented from bending due to the weight of the rainwater, and the problem of the lid coming off can be completely eliminated.

In addition, since rainwater is collected and discharged in an endless water collection groove adjacent to the joint edge of the lid that joins the upper edge of the container body, the load due to rainwater is transferred to the joint edge side of the container. It is possible to improve the adhesion between the body and the lid, and there is no need to worry about sewage flowing into the container.In addition, the drain hole provided on the lid fits into the fitting part provided on the upper edge of the container. This has the effect of preventing the lid from rattling.
