Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a drip absorbing sheet that separates and absorbs drip generated from marine products, meat and vegetables, for example.

[0002]

[Prior art]

 Merchandise from which drips such as marine products, meat and vegetables (for example, sea urchin, how much, tarako etc.) are stored in containers and shipped, and are often stored in containers and browsed over the counter. However, if the product from which such drips spill out is stored directly in the container as it is, freshness and quality will be reduced due to the spilled drip and the product value will be reduced. The drip is absorbed by the absorbent paper by laying paper and placing it on the absorbent paper.

In the case of placing on the absorbent paper, if the amount of drip flowing out is large, the amount of absorbed drip is limited, so that the drip is not sufficiently separated, and the product is directly connected to the drip absorbed by the absorbent paper. Touching may lead to a decrease in quality. Also, because the product is in direct contact with the absorbent paper, it absorbs more drip than necessary and dries the product.

[0004] Therefore, the present applicant has provided a drip separation sheet of Japanese Patent Application No. 2000-536969 to solve this problem. The drip separation sheet 11 is a synthetic resin sheet integrally formed with corrugated irregularities 12 as shown in FIG. 11 and provided with slits 13 in appropriate places. For example, as shown in FIG. The absorbent paper 15 is laid on the bottom surface of 14 and laid on top of it. The product from which the drip flows out is stored on the drip separation sheet 11.

The drip flowing out of the product placed on the drip separation sheet 11 flows below the corrugations 12 and the slits 13 and is separated from the product. At this time, since the drip separation sheet 11 has a height (spacing) between the bottom surface of the container 14 and the corrugated unevenness 12, even if there is a large amount of drip, the drip separation sheet 11 is prevented from directly contacting the product. Is done. In particular, when the water-absorbing paper 15 is laid under the drip separation sheet 11, the effect is further increased because the drip that has flowed down is absorbed by the water-absorbing paper 15.

[0006]

[Problems to be solved by the invention]

 However, since the conventional drip separation sheet 11 and the water absorbing paper 15 are separate, both must be prepared separately. In use, the water absorbing paper 15 is first spread as shown in FIG. However, laying the drip separation sheet 11 on top of that is troublesome and troublesome twice. It is also expected that the water-absorbing paper 15 may be out of stock (forgotten to use or forgotten to purchase) and cannot be used together. An object of the present invention is to provide an easy-to-use drip-absorbing sheet which solves the above-mentioned problems, has good separation of the drip flowing out, has high water absorption performance, and can maintain quality for a long period of time.

[0007]

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, FIG. 3 is an exploded perspective view showing a use state, and FIG. 4 is a sectional perspective view showing a use state.

In FIG. 1, a drip-absorbing sheet 10 is formed of a non-water-permeable synthetic resin sheet and integrally formed with corrugated irregularities 2, and a non-woven fabric is provided on the back surface of the non-water-permeable sheet 1 provided with a water-permeable portion 3 in a proper position. Alternatively, a sheet 4 made of paper having water absorbency and water retention (hereinafter, referred to as a sheet having water absorbency) 4 is attached to the valley 2a of the corrugated unevenness 2 as shown in FIG. It is not adhered to the back surface, and is provided with a gap (gap) 2c formed between the projection 2b.

The water-impermeable sheet 1 is formed of a water-impermeable synthetic resin sheet, and may be a conventionally known one. As an example, a synthetic resin sheet of polystyrene, polypropylene, or the like can be given. In particular, the synthetic resin sheet forming the water-impermeable sheet 1 is preferably made of a material and a thickness that provide an appropriate cushioning property in combination with the corrugations 2. By doing so, the corrugated unevenness 2 is retained and the drip that flows out flows down, and even if an unexpected external force is applied from above the product, it cushions and cushions the product without damaging the product. .

The water impermeable sheet 1 is provided with a water passage section 3. The water passage section 3 is a passage through which the drip flowing out of the product passes through the non-permeable sheet 1 and flows out from the front surface to the back surface side, and may include a plurality of slits and a plurality of small holes. . In the illustrated embodiment, the water passage 3 is indicated by a slit. The position and direction in which the slit is provided are not particularly limited, but are preferably in a direction intersecting the corrugated unevenness 2 as shown in the drawing. For example, besides the illustrated slit, an oblique slit can be exemplified. When a plurality of small holes are provided as the water passage part 3, it is preferable to provide the small holes in the valleys 2a of the corrugated unevenness 2. This is because the drip that has flowed out flows down into the valleys 2a of the corrugations 2 and is collected.

Further, as the irregularities 2 of the waveform, in addition to the normal waveform shown in the drawings, an S-shape, a spiral shape, a multi-circle shape, and the like can be exemplified. These irregularities in the waveform may be intermittent, that is, interrupted on the way.

On the back surface of the water-impermeable sheet 1, a water-absorbing sheet 4 made of nonwoven fabric or paper adheres to the valley 2 a (including the vicinity of the valley 2 a) of the corrugated unevenness 2 and is convex. The gap 2c is formed between the projection 2b and the back surface of the portion 2b so as to be non-adhesive. The reason why the water-absorbent sheet 4 is not adhered to the entire back surface of the water-impermeable sheet 1 but is adhered only to the valleys 2a of the corrugated unevenness 2 is that the water-absorbent sheet 4 is attached to the water-impermeable sheet 1. This is because, when adhered to the entire back surface, the swelling property when absorbing water is reduced and the water absorption performance is reduced, and a gap is formed between the water-impermeable sheet 1 and the sheet 4, into which drip enters. This is to improve the water retention performance, and furthermore, by forming the gap 2c, it is possible to maintain a gap between the product and the drips, which can prevent the drips from flowing out. is there.

The nonwoven fabric forming the water-absorbent sheet 4 is made of natural fibers such as cotton, wool, pulp, synthetic fibers such as polyethylene, polyester, and polypropylene, and recycled fibers as raw materials. Examples of the paper include those manufactured using pulp and synthetic resin fibers alone or as a mixture.

The drip-absorbing sheet 10 is laid, for example, in a container 6 as shown in FIG. 3, on which a product, for example, sashimi S, from which a drip flows out, is stored. However, the drip flowing out of the product placed on the drip absorbing sheet 10 flows down below the corrugated unevenness 2 and the water passage portion 3 and is separated from the product, and the separated drip is separated from the water passage portion 3 Then, the water flows out to the back side of the water-impermeable sheet 1 and is absorbed by the sheet 4 having water absorbency. The drip absorbed by the water-absorbing sheet 4 has an interval between the stored product S due to the unevenness 2a and the space 2c, and therefore does not come into contact with the placed (stored) product S.

In addition, since there is a height (space 2 c) between the placed product S and the bottom surface (water-absorbent sheet 4) of the container 6 due to the corrugated unevenness 2, a large amount of drip is generated. Even if there is, there is no direct contact with the product. Further, since the water-absorbing sheet 4 is adhered only to the valleys 2a of the corrugated irregularities 2 of the water-impermeable sheet 1, the swelling performance upon absorbing water is small and the water absorbing performance is not reduced.

FIG. 5 is a perspective view showing a modification of the above embodiment, FIG. 6 is a sectional view taken along the line BB of FIG. 5, FIG. 7 is an exploded perspective view showing a use state, and FIG. It is. In this example, the water-absorbing sheet 4 provided by bonding to the valleys 2a (including the vicinity of the valleys 2a) of the corrugations 2 on the back surface of the water-impermeable sheet 1 has a corrugation corresponding to the corrugations. The rest is the same as in the above embodiment. Also in this example, the water-absorbing sheet 4 is not adhered on the back surface of the convex portion 2b, and forms a small gap 2c. However, if the back surface of the convex portion 2b is not adhered, there is not necessarily a gap between the back surface of the convex portion 2b and the sheet 4 having water absorbency.

Also in this example, the drip absorbing sheet 10 is laid in a container 6 as shown in FIGS. 7 and 8, and a product from which a drip flows out, for example, a sashimi S is placed and stored. Yes, the rest is the same as the previous embodiment. According to the present example, the water-absorbent sheet 4 has a gap between itself and the convex portion 2b of the water-impermeable sheet 1 and the space 2d is formed between the sheet 4 and the bottom of the container 6. Even if 4 becomes heavy due to water absorption, there is room to hang down and water is retained in the gaps, so that the water absorption and water retention performance is improved.

FIG. 9 is a cross-sectional view corresponding to the line of FIG. 1A-A showing another embodiment of the present invention, and FIG. 10 is a cross-sectional view of a modification of the embodiment of FIG. 9 corresponding to the line of FIG. It is sectional drawing. In this embodiment, a water-absorbent sheet 5 made of non-woven fabric or paper is adhered to the back surface of a water-impermeable sheet 1 integrally formed with corrugated irregularities 2 using a water-impermeable synthetic resin sheet. Then, a water-absorbent sheet 4 formed of a nonwoven fabric or paper is adhered to the valley portion 2a of the corrugated unevenness 2 and formed on a two-layer sheet provided with a water passage portion 3 at an appropriate position. The second embodiment is the same as the above-described embodiment except that a gap 2c is formed between the first and second portions 2b. Therefore, the same components are denoted by the same reference numerals and detailed description thereof will be omitted. According to this embodiment, the water-absorbing performance is increased because the water-absorbing sheet 5 is closely adhered to the back surface of the water-impermeable sheet 1.

The drip-absorbing sheet 10 can be formed by cutting a sheet in which the impermeable sheet 1 and the water-absorbing sheet 4 are integrated, so that the drip-absorbing sheet 10 has water absorbing properties with the impermeable sheet 1 of any size. The sheet 4 and the sheet 4 can be formed to have the same dimensions.

[0023] The water absorption performance test was performed using only the same water-absorbing sheet as the water-absorbing sheet 4 according to the present invention and the drip-absorbing sheet shown in Figs. 5 and 6 of the present invention. The invented drip-absorbing sheet had 2-3 times the water absorption performance. This is because the drip-absorbent sheet of the present invention is more than the water-absorbent sheet alone, because the water-absorbent sheet itself absorbs water and drip enters the gap between the water-impermeable sheet and the water-absorbent sheet to retain water. It is considered to be.

[0024]

[Effect of the invention]

 As described above in detail, the present invention has the following effects. (1) The drip flowing out of the product placed on the drip absorbing sheet flows down below the corrugated unevenness and the water passage portion and is separated from the product. In particular, the drip is easy to flow down due to the corrugations, and is reliably separated. (2) The separated drip flows out to the back side from the water passage portion and is absorbed by the sheet 4 having water absorbency. The drip absorbed by the water-absorbing sheet 4 does not come into contact with the placed product due to the corrugated unevenness and space, so that the quality can be maintained for a long time. (3) In addition, since there is a height (interval and space) between the placed product and the bottom surface of the container (water-absorbing sheet 4) due to the unevenness of the waveform, there is a large amount of drip, Even if it cannot be absorbed by the water-absorbing sheet, it does not come into direct contact with the product, and the quality is maintained. (4) The water-absorbing sheet is adhered only to the corrugated valleys (including the vicinity) of the water-impermeable sheet, so that the swelling property upon absorbing water does not decrease, and the water absorbing and water retaining ability is improved. It is extremely expensive. (5) The drip that has flowed out flows out to the back side from the water passage portion and is absorbed by the sheet having water absorbability, so that the drip does not remain on the front side of the sheet and the appearance can be favorably maintained. (6) If a water-absorbing sheet is provided in close contact with the back surface of the water-impermeable sheet, the water-absorbing performance is increased by that amount. (7) Since the water-impermeable sheet and the water-absorbing sheet are integrated, it is convenient to use, and can be formed by cutting the integrated water-impermeable sheet and the water-absorbing sheet. Therefore, both can have the same dimensions. (8) Since the product placed on the drip-absorbing sheet does not come into direct contact with the water-absorbing sheet, the product does not deteriorate due to excessive absorption of moisture and drying.
