Description

For the liquid absorbing layer 10, it is preferable to use a pulp nonwoven fabric mainly composed of pulp fibers, and it is more preferable to use an airlaid pulp nonwoven fabric. The pulp nonwoven fabric may contain fibers or binders of thermoplastic resin, but preferably has a high pulp content. Although there is no restriction | limiting in particular of the mass of the liquid absorption layer 10, Typically, it is 30-120 g / m < ² >. The thickness of the liquid absorbing layer 10 is not particularly limited, but in the case of the food container 1 used for foods such as sashimi and raw meat where the drip liquid affects the freshness of the food, the ability to absorb the drip liquid is secured. Therefore, it is preferable to use the liquid absorbing layer 10 having a thickness of 0.50 mm or more.

As shown to Fig.4 (a), in the food container 1 of this invention, the test liquid dripped at the bottom face 2 moves to the 2nd pressing groove 12 of the surrounding wall surface 4, and also the 2nd pressing groove 12 of the surrounding wall surface 4 is. Was retained after being diffused to the part where no was formed. Moreover, the part which the test liquid has not spread | diffused remained in the part in which the 2nd pressing groove 12 of the surrounding wall surface 4 was not formed. On the other hand, in the comparative example, although the mass of the water absorbent paper is the same as the mass of the airlaid pulp used in the present invention, the absorption amount is low, and a part of the test liquid remains on the surface of the container without being absorbed. Was. Moreover, as shown in Table 1, even when edible oil was used as the test solution, the food container 1 of the present invention showed higher absorbability than the comparative example, and therefore the food container 1 of the present invention has much moisture. It turns out that it is suitable not only for side dishes but also for side dishes with a lot of oil.
