Description

[Detailed description of the invention] [Field of industrial application] This invention is a drip liquid that is used under the packaging, display, or preservation of perishable products such as vegetables, fruits, fish and shellfish, etc. Regarding absorbent sheets.

[Prior Art] Since fresh products such as vegetables, fruits, fish and shellfish are living organisms, juices such as fruit juice and meat juice ooze out during distribution or product display. Juices such as fruit juices and meat juices from fresh produce that seep out to the outside,
If you leave perishables contaminated with so-called drip liquid, the perishables will be damaged or become unsanitary, reducing the value of the product. Therefore, these drip liquids should be removed. BACKGROUND ART Conventionally, it has been common practice to place an absorbent sheet under perishables to absorb liquid.

This conventional absorbent sheet is, for example, made by stacking two water-permeable sheets and storing an absorbent material therebetween in the form of a layer of a certain thickness.

[Problems to be solved by the invention] However, the above-mentioned conventional drip liquid absorption sheet has the following problems:
When perishables are placed on top of the sheet, the perishables come into direct contact with the sheet, and as a result, the drip liquid absorption sheet absorbs not only the drip liquid but also the moisture in the perishables. However, there was a problem that the freshness of perishable products deteriorated.

The present invention solves these conventional problems, and allows moisture contained in fresh foods, which is necessary to maintain freshness, to naturally ooze out from the surface of fresh foods without absorbing them. To provide a drip liquid absorbent sheet for perishable products that absorbs only drip liquid.

[Means for solving the problems] The structure of the present invention for solving the above-mentioned conventional problems is shown in FIGS. 1 and 2, which correspond to embodiments of the present invention.
To explain the diagram, the drip liquid absorbent sheet for perishable products of the present invention has a water absorbing material layer 3 disposed between two sheets 1 and 2, at least one of which has water permeability, and It is constructed by disposing on the surface a slatted part 4 in which a large number of pipes or rods made of a non-water-absorbing material are arranged in a slatted manner.

[Function] Perishables are placed on the slatted part 4, which is made up of a large number of tubes or rods arranged in a slatted shape. Then, the drip liquid exuding from the fresh product drips onto the drainboard-shaped portion 4. The drip liquid dripping onto the grate-like part 4 passes between the grate of the grate-like part 4, and further,
The water is absorbed into the water-absorbing material layer 3 through one of the water-permeable sheets 1 located below.

In the absorbent sheet of the present invention, the sheet 1 containing the water-absorbing material layer 3 does not come into direct contact with perishables, and the slatted portion 4 is interposed between them, so even the moisture contained in the perishables is forcibly absorbed. Only the drip liquid seeping out onto the drainboard-like portion 4 is absorbed by the water-absorbing material 3 below.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a perspective view of a drip liquid absorbing sheet for fresh produce according to the present invention, and FIG. 2 shows an enlarged sectional view thereof.

In the figure, 1 is a sheet on the front side, 2 is a sheet on the back side, 3 is a water-absorbing material arranged in a layer with a predetermined thickness between these sheets 1 and 2 (hereinafter also referred to as a water-absorbing material layer), and 4 is a sheet. This is a slatted part arranged on the surface of 1.

The front sheet 1 is made of water-permeable material such as absorbent paper or nonwoven fabric, and the back sheet 2 is made of water-permeable material such as absorbent paper or nonwoven fabric.
As with the front sheet 1, a water-permeable material such as absorbent paper or nonwoven fabric or a water-impermeable material is used. A water-absorbing material layer 3 is formed between these sheets 1 by, for example, uniformly scattering high-molecular absorbent polymer powder. In order to prevent the water-absorbing material layer 3 from coming out from between the two sheets 1 and 2, the edges of the two sheets 1 and 2 are joined by welding or sewing to form a sealed bag-like shape as a whole. be done.

In addition, the slatted portion 4 has a large number of pipes 5 (straws) made of synthetic resin arranged in parallel on the surface of the sheet 1. For example, the straws 5 made of vinyl chloride or polyethylene are placed on the sheet 1. These straws 5 are lined up and heat-sealed at regular intervals in a width of 2 to 5 mm in the length direction and the direction perpendicular to the length direction, and the adjacent straws 5 and the straws 5 and the sheet 1 are welded together at the heat-sealed portion 6. be. In addition, an appropriate gap is formed between the many straws 5 arranged side by side so that the drip liquid can easily escape downward.

The constituent parts of the drainboard-shaped portion 4 are not limited to the hollow tubular shape (straw-like shape) shown in the drawings, but may be solid rod-shaped, and the cross-sectional shape is not limited to circular, but may be square or other shapes. Each tube or bar of the slatted portion 4 may be partially fixed on the sheet 1, if not in its entirety.

FIG. 3 shows a drip liquid absorbing sheet according to another embodiment of the present invention, in which a waterproof sheet 7 such as a polyethylene thin film is pasted on the back side of the back side sheet 2. When the back sheet 2 is made of a water-permeable material, the drip liquid absorbed by the water-absorbing material 3 stays in the water-absorbing material layer 3, and although the water-absorbing material layer 3 has a water-retaining effect to some extent, some The water oozes out through the sheet 2 to the back side, so the waterproof sheet 7 is provided to prevent this. Therefore, if the absorbent sheet 2 is water-impermeable, it will not have such a structure.

Therefore, drip liquid absorbing sheets constructed in this way are widely used for displaying fish and shellfish, for placing them on trays for fresh fish, and as packaging and preservation materials for other perishable products such as fruits, vegetables, and fresh flowers. can.

[Effects of the invention] As described above, the drip liquid absorption sheet for perishables of the present invention is such that when perishables are placed on the slatted part, the perishables are absorbed into the sheet or water absorbent with the slatted parts in between. Since it comes into contact with the material, only the drip liquid that naturally comes out from fresh products is treated to absorb water.
It does not absorb even the moisture that is present in fresh foods and is necessary to maintain their freshness.

Therefore, the drip liquid absorption sheet for perishable products of the present invention can hygienically treat drip liquid from perishable products while maintaining the freshness of the perishable products, and can improve the product distribution process of packaging and displaying perishable products. It is also extremely useful and can be widely used for food preservation at home.
