Description

[Detailed Description of the Invention] The present invention relates to a heat insulating container made of synthetic resin such as expanded polystyrene.

Some insulated containers consist of a container body made of synthetic resin such as styrofoam and a lid that is removably attached to the top of the container, and are used to transport vegetables, fruits, etc. Widely used for storage.

By the way, when transporting or storing perishable foods such as vegetables and fruits, such insulated containers require pre-cooling, oxygen supply, etc. when transporting or storing perishables for a long period of time. ventilation may be performed. For this reason, some lids have a small ventilation lid removably attached to a part of the lid.

However, when such conventional insulated containers are stacked in multiple tiers, the small lids of the lower stacked insulated containers cannot be attached or removed from the outside, so it is necessary to ventilate the containers after stacking with the small lids attached. If the ventilation is to be stopped after stacking with the small lid removed, it must be lowered and stacked again after removing the small lid. In either case, the problem was that the work was extremely difficult.

The present invention was developed in view of the above circumstances, and an object of the present invention is to provide a heat-insulating container that can easily vent and stop ventilation even when stacked in multiple tiers.

Hereinafter, the present invention will be explained in detail with reference to examples.

FIGS. 1 and 2 show a heat-insulating container according to an embodiment of the present invention.

This heat-insulating container A has a container body 1 made of a synthetic resin such as styrofoam having heat-insulating properties.
and a lid 2 removably attached to the upper part of the lid. A small ventilation window 11 is provided at the upper side wall of the container body 1 and the corresponding end of the lid body 2.
and a guide notch 21 are provided, respectively. This ventilation small window 11 and guide notch 21
A small lid 3 is removably attached to the holder. The small lid 3 has protrusions 31 provided on both sides thereof,
31 is adapted to be inserted into and removed from guide grooves provided on both sides of the small ventilation window 11 of the container body 1. As will be explained later, the portion of the side wall of the container body 1 below the small ventilation window 11 has a sloped portion 14 that slopes appropriately inward to allow the small lid 3 to be removed upward. It is becoming. A gripping recess 15 is provided at a predetermined location on the side wall of the container body 1 .

In this heat-insulating container A, the lower part of the small ventilation window 11 of the container body 1 has an inclined part 14 that slopes inward as appropriate, so that it can be stacked in multiple stages as shown in FIG. , lower container body 1
The small lid 3 removed from the container body 1 can escape into the escape space formed by the sloped part 14 of the upper container body 1. Also, the removed small lid 3
If you want to reinstall it, you can use the escape space to do so as well.

As explained above, according to the present invention, even when stacked in multiple tiers, the small lid removed from the lower tier container body can escape into the escape space formed by the sloped part of the upper tier container body, and Since the reverse can also be performed, ventilation can be easily performed even when stacked in multiple stages, and ventilation can also be easily stopped.

In addition, since the small ventilation window is provided on the side wall of the container body, the actual ventilation area of the small ventilation window does not change even when stacked in multiple tiers, and the desired ventilation effect can be obtained. I can do it. In addition, since the attachment/detachment direction of the small lid is vertical, even if the lid is stacked in multiple tiers and tilts for some reason, or even if it tilts during transportation by a worker or a car, the lid will never fall. do not have. Furthermore, a part of the side wall of the container body is made into an inclined part to allow the small lid to be removed upwards, and the small lid is installed and removed in the vertical direction. Even if there is no gap in between, the small lid can be easily attached and detached.
