Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple sealed bag suitable for transporting live fish and the like.

[Prior art]

When transporting live fish, in order to continue its life functions,
It is necessary to supply water and oxygen, remove waste products, and maintain an appropriate water temperature. For this reason, vehicles with water tanks or tanks are used to transport large quantities from production sites to collection sites, but when transporting small quantities from collection sites to consumers, etc., transportation containers are inexpensive and a one-way method is used. Due to certain requirements, for example, a plastic bag made of thin polyethylene cloth is used. That is, a predetermined amount of water and live fish are placed in a plastic bag, an oxygen injection hose is inserted through the opening of the plastic bag, and oxygen gas is ejected to replace air. Then, tie the opening of the plastic bag with string to seal it. Or,
A back-in-box is used, in which the plastic bag is placed in an outer box such as a cardboard box.

[Problem that the invention seeks to solve]

Plastic bags used as containers for transporting live fish in small quantities are inexpensive and suitable as one-way bags, but their shape is unstable, making it difficult to put water and fish in and out. In addition, it took a lot of effort to tie the opening of the plastic bag with a string and seal it, and the seal was not perfect, which caused not only oxygen gas but also water to leak during transportation. It may also be possible to tie the opening of the plastic bag with a clip or the like, but plastic bags tend to wrinkle and are not perfect in terms of sealability. Also, Jitsugan Sho 61-74365
As shown in No. ``Aquariums for Transporting Live Fish'', there are also bags that fill water and fish from the top end and form an entry/exit passage leading to the interior from the bottom end of the bag. In this case, water pressure inside the bag and the close contact of the soft film may make it possible to completely maintain watertightness and internal gas tightness, but the problem of making such a complicated bag is that it is costly and labor-intensive. There is.

Therefore, an object of the present invention is to provide an inexpensive bag that is easy to handle, has excellent sealing properties, and is suitable for transporting live fish.

[Means to solve the problem]

In order to achieve this purpose, the bag for transporting live fish of the present invention has a vertical cylindrical body for water/fish entry and exit connected to one side wall, and a check valve is provided on the passage from this vertical cylindrical body to the inside. It consists of a back main body made of soft resin and a clip system of a round bar and an elastic notched vibrator. It is characterized by being sealed.

[Effect]

The main body of the bag is made of soft resin, so it is inexpensive and suitable for a one-way system, but it has a more solid shape than a plastic bag, and allows you to easily put in and take out water, live fish, etc. from the opening at the top of the vertical cylinder. It can be folded when in use. Since we use a clip system consisting of a round bar and an elastic notched vibrator, first we wrap the vertical cylinder of the bag body around the round bar, and when we fit the elastic notched vibrator to this round bar, the opening of the vertical cylinder can be squeezed and sealed.

After sealing with the clip system, by turning the bag body upside down, water tightness and internal gas tightness can be completely maintained due to the close contact of the soft resin check valve.

〔Example〕

Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings.

FIGS. 1 and 2 are schematic diagrams of a bag main body 1, which is formed of a soft resin such as soft polyethylene into a substantially rectangular parallelepiped shape. For this reason, it has a more solid shape than a plastic bag, for example, L = 270 mm, Wl = 1 6 5
mm, W2=200 mm, H=200 mm, and internal volume 15j' are used. Reference numeral 2 denotes a vertical cylindrical body connected to one side wall of the bag main body 1, through which water, live fish, etc. can be taken in and taken out through an opening 21 at the top of the vertical cylindrical body 2. It is familiar to Reference numeral 3 denotes a gas injection valve having a backflow prevention mechanism for injecting oxygen gas and the like.

FIG. 3 shows a clip system for sealing the opening 2l. This clip system consists of a round bar 6 whose length is slightly longer than the opening 2l and an elastic notched pipe 5. Round bar 6
is a lightweight and inexpensive hard vinyl chloride pipe with an outer diameter of 20 mm, for example, and the elastic notched pipe 5 is a hard vinyl chloride vibrator with an inner diameter equal to or slightly smaller than the outside diameter of the round bar 6, with a notch in the axial direction. A portion 52 is formed to have a substantially C-shaped cross section, and wing portions 5l made of soft vinyl chloride are integrally formed at both end edges of the notch portion 520.

Next, the procedure for packaging live fish will be explained. First, water and live fish, for example, about 10 to 50% of the effective internal volume are put into the bag body l. Next, press the top of the bag body I to expel the air inside. Then, from this state, when the vertical cylinder body 2 of the bag is wrapped around the round bar 6 and the notch part 52 of the elastic notch pipe 5 is pushed in from above, the elastic notch pipe 3 is elastically deformed and the notch part 52 is expanded and can be easily fitted with one touch, as shown in FIG. Therefore, the vertical cylindrical body 2 of the bag body l is the round bar 6.
and the elastic notched pipe 5 are held together under pressure, and the opening 2l is sealed. Furthermore, if a retainer 61 is provided at the top of the vertically simplified body 2 as in this embodiment, it will not come off even if a pulling force is applied. Next, when the bag body 1 is turned over from this state, a passage 2 leading from the vertical cylinder body 2 to the bag body 1
2 faces downward, and the check valve 4 made of soft resin joined to one side wall of the bag body 1 is brought into close contact with the portion 11 of the bag body 1. Next, when oxygen gas is injected from the gas blowing plug 3, the bag main body 1 is inflated and restored to its normal shape as shown in FIG. 5, and the packaging operation is completed.

In such a configuration, the clip system maintains watertightness and airtightness of the gas sealed inside, and even if wrinkles occur when wrapping the vertical cylinder 2 around the round bar 6, the inside of the bag body l can be maintained. A check valve 4 provided below allows for complete sealing with water pressure and oxygen pressure. With such a self-sealing mechanism, water and oxygen leaks can be prevented without the need for troublesome airtight work such as tying the outlet with a string or folding it and securing it with tape. Further, since the structure of the check valve 4 is extremely simple compared to the conventional one, it can be manufactured easily and cheaply.

The live fish of the present invention includes shrimp and crab, and the size of the bag may vary depending on the type and number of fish.
It is preferable to have a small size because the work involves turning it over.

Such a bag can be used as is, but it may also be used in an outer box such as a corrugated pole.

In this case, since the bag body l is approximately rectangular, there is no wasted space during air or land transportation, and loading efficiency is very high. This bag for transporting live fish can withstand long-term transportation because there is no oxygen leakage, and it can be transported as-is from the production area to restaurants and homes.

Furthermore, it can be easily folded and transported when not in use.

〔effect〕

As explained above, the main body of the bag for transporting live fish of the present invention is made of soft resin, so it is inexpensive and suitable for a one-way system. can be easily taken in and out from the opening at the top of the vertical cylinder, and can be folded when not in use.

Since a clip system consisting of a round bar and an elastic notched pipe is used, first wrap the vertical body of the bag body around the round bar, and then fit the elastic notched pipe to this round bar.
The opening of the vertical body can be compressed and sealed. After sealing with the clip system, by turning the bag body upside down, the soft resin check valve can be tightly attached to completely maintain watertightness and internal gas tightness.
