Description

[Detailed Description of the Invention] The present invention relates to a can-type container containing a substance to be heated and a substance for heating the substance.

The applicant first stores a fumigation agent (substance to be heated) and a heating pyrogen (substance for heating) in a container,
We developed a type of fumigation equipment that vaporizes the chemical by heating the former with the latter. This type of fumigation equipment is usually sealed intermediately with aluminum wheels, synthetic resin film, etc., and then packaged externally in order to isolate the fumigation agent and heating exothermic substances from the outside air until they are used. Since such intermediate packaging complicates the packaging process and causes inconvenience in use, it is desirable to omit it as much as possible.

The present invention has been developed in view of the above-mentioned needs, namely, the present invention is a canned food type in which the upper lid and the lower lid are each provided with a pull-top opening means, and an inward bead portion is formed on the upper part of the peripheral wall. an outer container;
The inner container is suspended from the inward bead of the peripheral wall of the outer container, and further includes a water-permeable or air-permeable bottom member laid at the bottom of the outer container, so that the outer container does not come in contact with water or air. The present invention relates to a can-type container containing a substance to be heated and a substance for heating the substance, characterized in that a pyrogenic substance that generates heat and a substance to be heated are housed in the inner container.

The present invention will be described below based on the illustrated embodiments of the present invention. The figure shows an example where the substance to be heated is a fumigation agent and the container of the present invention is applied as a fumigation device; however, the substance to be heated may be other foods that require heating,
It may also be a drink or the like.

The can-type container according to the present invention includes an outer can-type container 1 in which pull-top opening means 6 and 7 (or 7') are provided on an upper lid 8 and a lower lid 9, respectively, and a can-type container 1 built in an upper part 1a of the outer container 1. It includes an inner container 2 and a water-permeable or breathable bottom member 10 (or 11) laid on the bottom of the outer container 1.

The outer container 1 has an inwardly directed bead portion 3 at the upper part of the peripheral wall 1', and the inner container 2 is suspended on this bead portion 3.

The pull-top opening means may be either a full opening type or a partial opening type, and in the embodiment shown in FIGS.
The lower lid 9 is provided with a partially opening type opening means 7',
Further, in the embodiment shown in FIGS. 4 to 6, a fully opening type opening means 6 is provided on both the upper lid 8 and the lower lid 9.
and 7 are provided.

The bottom member 10 (or 11) placed at the bottom of the outer container 1 needs to have air permeability or water permeability, and in the embodiment shown in FIGS.
The bottom member 10 is made of fibrous pine, and the bottom member 11 is made of a perforated plate in the embodiments shown in FIGS. 4 to 6. It can be a raised bottom.

A bottom member 10 (or 1
A exothermic substance 5 that generates heat upon contact with water or air supplied through 1) is housed. Examples of such exothermic substances 5 include the following.

a Compound that generates heat due to hydration reaction, such as calcium oxide, magnesium chloride,
Examples include substances that react exothermically only by adding water, such as aluminum chloride, calcium chloride, and iron chloride.

b Combinations of metals or metal compounds that generate heat through oxidation reactions and auxiliary agents, etc., such as mixing iron powder and oxidizing agents (ammonium chlorate, etc.), metals and metal oxides or oxides that have a smaller ionization tendency than the metals. A method in which a mixture of iron and at least one of potassium sulfate, iron sulfide, metal chloride, iron sulfate, etc. is brought into contact with water and oxygen, a method in which a mixture of iron and at least one of potassium sulfate, iron sulfide, metal chloride, iron sulfate, etc. Examples include a method in which a mixture of a small metal with a halide is brought into contact with water, a method in which a mixture of a metal and a bisulfate is brought into contact with water, and a method in which water is added to a mixture of aluminum and an alkali metal nitrate.

c) A method that utilizes the oxidation reaction of metal sulfide, for example, a method in which a mixture of sodium sulfide and iron carbide is brought into contact with oxygen can be exemplified.

A fumigation agent 4 as a substance to be heated is placed in the inner container 2 on the upper part of the outer container 1 and is heated by the heat generated by the pyrogenic substance using the inner container 2 as a heating heat transfer surface.
is stored. The drug 4 is not particularly limited, but examples include insecticides, insecticides, bactericidal agents, repellents, detractors, plant growth regulators, herbicides, and perfumes.

A foaming agent may be added to the drug 4. Preferred foaming agents include azodicarbonamide (foaming temperature 200 to 210°C), benzenesulfonyl hydrazide (foaming temperature 100 to 160°C), and the like.

In use, the canned container according to the present invention has an upper lid 8 and a lower lid 9 with pull-top opening means 6 and 7.
(or 7'). At the same time as this opening, air enters through the bottom member 10 (or 11), or water enters by immersing the lower part of the outer container 1 in water, so that the exothermic substance 5 comes into contact with air or water and generates heat. Due to the heat generated by the pyrogen 5, the medicine 4 in the inner container 2 is heated and fumigated using the inner container 2 as a heating heat transfer surface. Preferably one with good properties.

In addition, the inner container 2 may be damaged due to the impact caused when the upper lid 8 is opened.
To prevent the drug 4 from spilling out from inside, the mouth end of the inner container 2 is sealed with a heat-melting film, such as a film (not shown) made of polyethylene that melts at a temperature of 250°C or less. You can keep it. Since this film is melted and opened by the heat generated by the exothermic substance 5, there is no need to peel it off by hand.

If the exothermic substance 5 is an oxidative exothermic substance, it may be formed into a sheet and adhered to the back surface of the inner container 2.

The canned container according to the present invention completely shuts out the heated substances and exothermic substances stored inside from the outside air, and completely prevents deterioration caused by moisture absorption and air oxidation, unlike conventional products. There is no need for any intermediate hermetic packaging, which greatly simplifies product packaging.

Further, since it is a can type, it is structurally compact and easy to handle, and when in use, the upper and lower lids of the outer container can be opened using a pull-top opening means, making it extremely easy to use.

Furthermore, in the present invention, an inward bead portion 3 is formed on the peripheral wall of the outer container 1, and the inner container 2 is attached to the bead portion 3.
Since the inner container 2 is suspended, a storage space for the exothermic substance 5 can be formed between the outer container 1 and the inner container 2 without tightening the inner container 2 to the outer container 1. Therefore, according to the present invention, in a container having a canned-like structure composed of a composite outer container 1 and an inner container 2 in which a pyrogen 5 and a drug 4 (substance to be heated) are individually packaged, the inner container 2 is built into the outer container 1. This provides an advantage in that it is guaranteed that the top surface of the outer container 1 can be seamed with the same ease as normal seaming.

Furthermore, in the present invention, since the bottom member 10 (or 11) placed at the bottom of the outer container 1 has air permeability or water permeability, after the outer container 1 is opened, the exothermic substance is removed through the bottom member. Air or water can be easily supplied to 5, making it easy to use, and the bottom member prevents the exothermic substance 5 from spilling out, making it safe to use.
