Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fish egg packaging material capable of absorbing the drip coming out of the fish egg and visually recognizing the amount of the drip from the outside.

[0002]

[Prior art]

 Conventionally, fish eggs used for food, such as salmon roe, are separated from the ovaries and taken out, and then the required amount of egg grains are wrapped in cotton cloth and placed in a transparent polyethylene bag to prevent drying. In addition, it has been distributed by being housed in an outer box such as a wooden box.

In such a packaging form, the quality of the salmon roe can be distinguished without opening the packaging depending on the amount of the drip (juice) from the salmon roe that has soaked into the cotton cloth. It has been adopted.

[0004]

[Problems to be solved by the device]

 However, the conventional fish egg packaging method as described above has a problem in that the packaging of the fish egg is double and the packaging is time-consuming and unsanitary.

The present invention has been made to solve the above problems, and provides a packaging material for fish eggs that can absorb the drip that comes out of the fish eggs and can visually check the amount of drip from the outside. That is the purpose.

[0006]

[Means for Solving the Problems]

 The present invention has been made to achieve the above-mentioned object, and forms a non-woven fabric layer in contact with fish eggs, a pulp layer adhered to one surface of the non-woven fabric layer, and an outer layer, and is waterproof and light-transmissive. And a waterproofing layer having a waterproof property and a light-transmitting property, and an adhesive film sandwiched between the pulp layer and the waterproof layer for adhering the both, the pulp layer and the waterproof layer. And are partially bonded via the adhesive film to form a number of adhesive parts, and between adjacent adhesive parts and adhesive parts, a drip retaining part is provided between the pulp layer and the adhesive film. A packaging material for fish eggs, which is formed and has a space formed between the waterproof layer and the adhesive film.

[0007]

[Action]

 The present invention is configured as described above, and the fish eggs are wrapped in contact with the nonwoven fabric layer of the packing material for fish eggs. The drip from the roe penetrates the non-woven fabric layer, permeates into the pulp layer, and a part of the drip exudes into the drip holding part. It can be seen from the outside through the waterproof layer.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a fish egg packaging material, and the fish egg packaging material 1 includes a non-woven fabric layer 10, a pulp layer 11 welded to the nonwoven fabric layer 10, a waterproof layer 12, and an adhesive film. The pulp layer 11 and the waterproof layer 12 are partially adhered to each other through the adhesive film 13 to form a large number of adhesive portions 14, and between the adjacent adhesive portions 14 and 14. A lip retaining portion 15 and a space portion 16 are formed.

In the embodiment, the non-woven fabric layer 10 is made of a melt-blown non-woven fabric of ultrafine fibers of polyethylene and polypropylene, and the basis weight is preferably about 5 to 8 g / m ² .

The pulp layer 11 is made of water-absorbent paper having a basis weight of about 13 to 40 g / m ² , and the pulp layer 11 and the non-woven fabric layer 10 are integrated by being heat-welded to one surface of the nonwoven fabric layer 10. Is attached to.

The waterproof layer 12 is made of a waterproof and light-transmitting (transparent) polyethylene terephthalate film, and has a thickness of about 30 to 80 μm. The waterproof layer 12 may be a polypropylene film.

The adhesive film 13 is made of a waterproof and light-transmissive polyethylene film and has a thickness of about 10 to 30 μm. The adhesive film 13 is sandwiched between the pulp layer 11 and the waterproof layer 12. There is. Then, the pulp layer 11 and the waterproof layer 12 are integrally bonded and laminated in the bonding portion 14 with the bonding film 13 as a medium.

The adhesive portion 14 has a geometric pattern that is made opaque by adhesion, or a shape such as a mark or a character, and a large number of adhesive portions 14 having a repeating pattern thereof are formed (see FIG. 2). ). Therefore, the adjacent adhesive portions 14 are in a non-adhesive state, a space serving as the drip retaining portion 15 is formed between the pulp layer 11 and the adhesive film 13, and the waterproof layer 12 and the adhesive film 13 are formed. A space portion 16 is formed between and. The drip retaining portion 15 and the space portion 16 are formed symmetrically on the front and back sides.

Reference numeral 18 in FIG. 1 is a press roll having a projection for forming the adhesive portion 14, and forms a pressure contact portion with the cooling roll 19. Then, in the press-contact portion, the adhesive layer 13 extruded from an extruder (not shown) is sandwiched between the laminated material composed of the non-woven fabric layer 10 and the pulp layer 11 fed and the waterproof layer 12. Is applied to cure the adhesive film 3 and form the adhesive portion 14.

The packaging material 1 for fish eggs thus configured is used for packaging in a sheet form as it is, or formed into a bag shape by a two-side seal or a three-side seal and used for packaging. Then, as shown in FIG. 3, the fish eggs illustrated in the salmon roe 20 are packaged in the fish egg packaging material 1.

At this time, the drip 21 (shown by a small circle for convenience) that has exuded from the salmon roe 20 penetrates the nonwoven fabric layer 10 and permeates into the pulp layer 11, is retained in the pulp layer 11, and The drip 21 of the part is exuded and held in the drip holding part 15. Therefore, the drip 21 in the drip holding portion 15 is from the outside of the fish egg packaging material 1, that is, through the waterproof layer 12, the space portion 16, and the adhesive film 13 as shown by the double-dashed line arrow in FIG. The amount of the drip 21 can be visually recognized from the outside of the package.

Further, the holding action of the drip 21 of the pulp layer 11 and the waterproof layer 12 can prevent the dryer 20 from being excessively dried.

The present invention is not limited to the above description and the illustrated examples, and its embodiment can be modified without departing from the technical idea of the present invention.

[0020]

[Effect of device]

 The packing material for fish roe according to the present invention is constructed as described above, and absorbs the drip from the packed fish roe with the non-woven fabric layer and the pulp layer, and at the same time, drip oozes into the drip holding portion Since it is visible from the outside, the amount of drip can be checked and the quality of roe can be discriminated without opening the packaging.

Further, as compared with the conventional example, the fish eggs can be packaged without using a cotton cloth, so that the labor of double packaging can be omitted, and the fish eggs can be formed by forming the bag-like packaging material for the fish eggs. It is possible to obtain a packaging material for fish eggs that is easy to put and is inexpensive.

Furthermore, in forming the present packaging material for roe, high-temperature processing is performed for forming the adhesive portion, so that an extremely hygienic packaging material can be obtained.

Further, the pulp layer and the waterproof layer have an effect of preventing the fish eggs from being excessively dried and maintaining the freshness of the fish eggs for a long time.
