[Solution] A drip absorption mat 1 is characterized in that it is laminated in the order of a water-permeable surface sheet, an absorbent layer, and a back sheet from the surface in contact with food, and the back sheet is provided with an adhesive means 3 that allows it to be bonded to a packaging material 2, wherein the packaging material 2 is a tray.

Description

Technical Field

[0001] The present invention relates to a drip absorption mat used for absorbing drip liquid exuded from foods such as fresh fish and meat.

Background Art

[0002] Drip absorption mats are used for the purpose of absorbing drip liquid exuded from foods such as fresh fish and meat to prevent deterioration of the freshness and quality of the foods or to maintain their appearance. For example, it is widely practiced to lay the drip absorption mat under sashimi, sliced meat, or meat sold in trays at stores such as supermarkets. Also, after attaching the drip absorption mat to meat after finishing the operation of cutting muscles of various parts from the carcass, it is also carried out to pack it in a shrinkable bag (or a non-shrinkable bag) and distribute it.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, when using a drip absorption mat, when taking out foods such as fresh fish and meat and moving on to the next process such as cooking, since the drip absorption mat is firmly adhered to the food, there are sometimes cases where workers or housewives forget to remove the drip absorption mat. For example, there have even been cases where the drip absorption mat was cooked together or accidentally eaten. In particular, when the drip absorption mat contains a water-absorbing polymer, it has been a major problem.

[0005] This invention was made in view of the above-mentioned problems, and its purpose is to provide a drip absorption mat that will not be forgotten after use. [Means for solving the problem]

[0006] This invention was developed after careful consideration of the aforementioned problems. It was found that if the drip-absorbing mat can be attached to the inside of a tray or a shrinkable bag (or non-shrinkable bag), it will not come into contact with the food when removing fresh fish, meat, or other food items, and can be automatically removed together with the packaging. This prevents the accident of forgetting to remove the drip-absorbing mat, and thus led to the present invention.

[0007] In other words, this invention is (1) A drip absorption mat 1 characterized in that it is laminated in the following order from the surface in contact with food: a water-permeable surface sheet 11, an absorbent layer 12, and a back sheet 13, and the back sheet 13 is provided with an adhesive means 3 that allows it to adhere to the packaging material 2. (2) The drip absorbent mat 1 according to (1), characterized in that a bag is formed by a surface sheet 11 and a back sheet 13, and an absorbent layer 12 is sealed inside the bag. (3) The drip absorption mat 1 according to (1) or (2), characterized in that the adhesive means 3 is an adhesive sheet. (4) The drip absorption mat 1 according to any one of (1) to (3), characterized in that the packaging material 2 is a tray. This is the gist of it. [Effects of the Invention]

[0008] The drip-absorbing mat 1 of this invention has adhesive means 3 on the back sheet 13 that comes into contact with the packaging material 2, so that it becomes integrated with the packaging material 2 which is used and discarded at the same time. This prevents forgetting to remove the drip-absorbing mat 1 from foods such as fresh fish and meat, and has the effect of preventing accidents such as cooking the drip-absorbing mat 1 and food together, or in the worst case, ingesting the drip-absorbing mat 1, due to forgetting to remove the drip-absorbing mat 1. [Brief explanation of the drawing]

[Figure 2] This is a schematic cross-sectional view showing another example of the drip absorption mat 1 of the present invention. [Figure 3] This is a schematic cross-sectional view showing an example of the use of the drip absorption mat 1 of the present invention when the packaging material 2 is a tray. [Modes for carrying out the invention]

[0010] The drip absorption mat 1 of this invention is constructed by laminating a water-permeable surface sheet 11, an absorbent layer 12, and a back sheet 13 in that order from the front of the food such as fresh fish or meat, and the back sheet 13 is provided with adhesive means 3 that can adhere to the packaging material 2. More specifically, examples include a structure having a cross-sectional shape in which a water-permeable surface sheet 11, an absorbent layer 12, a back sheet 13, and adhesive means 3 are laminated in that order as shown in Figure 1, or a structure having a cross-sectional shape in which the absorbent layer 12 is sealed in sheet form inside a bag formed by a water-permeable surface sheet 11 and a back sheet 13, and adhesive means 3 is provided on the outside of the back sheet 13 as shown in Figure 2.

[0011] The surface sheet 11 constituting the drip absorption mat 1 of this invention is the part that comes into direct contact with food such as fresh fish and meat, and it is necessary that the drip liquid seeping from the food does not remain on the surface sheet 11 but quickly permeates through to reach the absorbent layer 12. Therefore, it is essential that the surface sheet 11 has water permeability to allow the drip liquid to pass through, and preferably it is non-hydrophilic and less permeable to the drip liquid. For example, perforated plastic films such as polyethylene film and polypropylene film with many liquid permeable holes, nonwoven fabrics, woven fabrics, etc. can be used. Among these, it is preferable to use a nonwoven fabric that has sufficient strength, excellent water permeability and a relatively small pore size, and in particular, if the packaging material 2 is a bag, it is preferable to use a nonwoven fabric that can be heat-sealed.

[0012] The absorbent layer 12 is not particularly limited as long as it has excellent absorbency of drip liquid. Examples include nonwoven fabric, nonwoven fabric containing a water-absorbent polymer in addition to crushed pulp, and water-absorbent sheets formed by sandwiching crushed pulp and a water-absorbent polymer with tissue paper or the like. The water-absorbent polymer is not particularly limited as long as it can absorb more than 100 times its own weight in water. Examples include copolymers of acrylic acid and vinyl alcohol, alkaline hydrolysates of graft copolymers of starch and acrylonitrile, and partially sodium salt crosslinked acrylic acid polymers. In this invention, it is preferable to use partially sodium salt crosslinked acrylic acid polymers, which are produced in large quantities industrially. Since the drip absorption mat 1 is required to be able to absorb a large amount of drip and not easily release the absorbed drip, it is common to use a superabsorbent polymer with a much larger absorption capacity in combination with pulp or nonwoven fabric, which are common absorbents.

[0013] Examples of the backing sheet 13 include plastic films such as polyethylene film and polypropylene film, nonwoven fabrics, or paper such as cardboard. In particular, when the drip absorption mat 1 of the present invention takes the form of an absorbent layer 12 enclosed in a bag formed from a surface sheet 11 and a backing sheet 13 as shown in Figure 2, it is preferable to use a material for the backing sheet 13 that can be heat-sealed to the surface sheet 11, such as a plastic film or nonwoven fabric. Note that "enclosed" means that the absorbent layer 12 is inside the bag and the bag has no opening. In this case, the drip liquid that seeps out from the food passes through the surface sheet 11 and is absorbed by the enclosed absorbent layer 12, and even if the absorbent layer 12 expands as a result of absorption, it has the effect of preventing it from leaking out of the bag.

[0014] And the adhesion means 3 provided on the backsheet 13 side is not particularly limited as long as it can adhere the drip absorption mat 1 of the present invention and the packaging material 2 through the backsheet 13. For example, those in which an adhesive is applied to the backsheet 13, or those in which one side of a double-sided adhesive sheet is attached to the backsheet 13 are exemplified. Further, even if this adhesion means 3 is arranged on the entire surface or an appropriate part of the backsheet 13, there is no problem as long as the drip absorption mat 1 and the packaging material 2 can be adhered so that they do not come off when taking out the food on the drip absorption mat 1.

Example

[0015] The usage method of the drip absorption mat 1 of the present invention will be specifically described with reference to FIG. 3. In this example, the drip absorption mat 1 having the structure shown in FIG. 2 was used. The drip absorption mat 1 of the present invention is laid on a tray 2 as a packaging material as shown in FIG. 3 and is adhered to the tray 2 by the adhesion means 3. Then, food A is placed on the drip absorption mat 1, and the whole is covered with a wrap film B. After a certain period of time (the time corresponding to the in-store display time for sales), the food A was taken out after removing the wrap film B. The drip absorption mat 1 had absorbed a large amount of drips and was adhered to the food A. And when taking out the food A, the drip absorption mat 1 remained adhered to the tray 2 and did not become part of the food A.

Industrial Applicability

[0016] Since the drip absorption mat 1 of the present invention remains adhered to the packaging material 2 through the adhesion means 3 even after use, when taking out foods such as fresh fish and meat from the packaging material 2, it is possible to prevent accidents such as accidentally taking out the drip absorption mat 1 together for cooking or, in the worst case, eating the drip absorption mat 1, enabling the safe use of the drip absorption mat 1.
