Drip sheet

Abstract

A drip-absorbent sheet which can absorb drip at the both surfaces and can store drip more than the absorption capacity of an absorption sheet. The drip-absorbent sheet (1) comprise a pair of thermoplastic sheets (3) joined to both surfaces of an absorption sheet (2) and defining an upper surface (11) and an lower surface (12) of the drip-absorbent sheet respectively and is adapted to be loaded foodstuff onto the upper surface, wherein a plurality of openings (4) are arranged at an interval in the thermoplastic sheet, liquid guide channels (5) continuously extending from peripheral edges (6) of respective said openings in a thickness direction of said thermoplastic sheet wherein each of the liquid guiding channels is diameter-reduced gradually as it extends toward a distal end (7) thereof,and at least at said bottom surface of said drip-absorbent sheet, said thermoplastic sheet faces said absorbent sheet with a surface (13) toward which said liquid guiding channels extend wherein saiddistal ends of said liquid guiding channels are joined to said absorbent sheet.

Description

technical field [0001] This invention relates to drip sheets for packaging meat, fish and the like. Background technique [0002] In recent years, foods such as meat and fish have been put in resin trays and packaged with plastic film and placed in stores or during distribution. At this time, for the purpose of absorbing the liquid (drip) seeping from the food, a liquid-absorbent sheet called a drip sheet or a water-absorbent pad is widely placed under the food or between the food. [0003] The inventors of the present application disclosed a technology in Patent Document 1, which is a drip absorbent pad laid under food that generates drips, has an absorbent sheet for absorbing drips, and is arranged on the absorbent sheet. The food-contacting porous surface sheet on the upper side prevents the color deterioration of the back side of the food in contact with the porous surface sheet by adjusting the air permeability in the plane direction and / or the thickness direction of t...

AI Technical Summary

Problems solved by technology

However, since the duct tube formed by stretching the surface layer enters the structure of the absorbent sheet, the volume of the absorbent sheet is reduced, so there is room for improvement in the drip storage capacity of the drip sheet.

In addition, since the catheter is formed by the manufacturing method of inserting and pulling out the needle, the back layer is easily deformed in the direction in which the hole is closed when the needle is pulled out, so the dripping liquid is not easy to leak from the back layer side. However, in addition On the one hand, it is also difficult to absorb drips from the back layer side
