Abstract

PURPOSE:To uniformize moisture absorbing effect in a vessel wherein one part is formed with an air-permeable body by forming mid-partitions for partitioning the vessel main body excepting the air-permeable body into a plurality of comparted chambers and packing drying agents to the insides of the comparted chambers respectively. CONSTITUTION:A vessel main body 2 is a rectangular parallelepiped in which one end 2a is made to a sharp shape and opening parts 2b are provided to the two opposite sides selected from among four sides. Further mid-partitions 11 for partitioning the vessel main body 2 into two or more comparted chambers 10 are provided and many notches 12a are penetrated to the mid-partitions 11. A permeable film 13 is bonded to the opening part 2b of the vessel main body 2 and a nonpermeable film 14 is bonded to the other opening part 2b. A desiccant 6 is packed in respective comparted chambers 10 to about (1/2-1/4) of the volume thereof. In this constitution, when plunging one end 2a of the vessel main body 2 into dry feed products, moisture is infiltrated through the permeable film 13 and trapped with the desiccant 6. At this time, since the desiccant 6 is packed in respective comparted chambers 10, moisture absorption effect does not differ in the upper and lower parts of the vessel 1. Furthermore the notches 12a are penetrated to the mid-partitions 11 and respective comparted chambers 10 are communicated and have moisture permeability and thereby moisture absorption effect is more uniformized.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a moisture absorber that prevents moisture absorption of substances such as foods that change in quality due to moisture absorption. Concerning vessels.

(Prior Art) Dried foods such as instant coffee, tea, and dried shiitake mushrooms are said to be delicious when they contain moisture of 50% to 40%.

On the other hand, it is said that bacteria that spoil the taste of food do not germinate and proliferate at humidity below 60%, so it is preferable to store food at a humidity below 60%, preferably between 50% and 40%. .

For this reason, traditionally, food was placed in airtight containers such as bottles and cans.
A bag or the like filled with a desiccant such as silica gel or calcium chloride is enclosed in a bottle or can to keep it moisture-proof to maintain the above-mentioned humidity level.

(Problem to be solved by the invention) However, with the above preservation method, no extra air force enters the interior of the bottle or can until the bottle or can is opened, and therefore the amount of moisture that gets mixed into the air is limited, so there is not much of a problem. However, once a bottle or can is opened and used, highly humid air flows in, and the dehumidified dry air inside the container instantly becomes the same state as humid air.

For this reason, desiccant agents such as silica gel and calcium chloride must be used to remove moisture from the container in a short period of time each time, and if the desiccant's moisture absorption capacity is exceeded, the food will no longer be able to maintain its dry state. It is something that changes in quality.

By the way, generally when a desiccant absorbs moisture, its volume expands by the amount of moisture absorbed, so the expansion is calculated in advance and the desiccant is filled in an amount smaller than the volume of the container. For example, a desiccant mainly composed of calcium chloride, which has a high hygroscopic ability, absorbs about 150% of its own weight of moisture, and therefore expands in volume equal to this moisture. For this reason, the moisture absorber has ~1/2 of its volume! In the initial stage, if the moisture absorber is stick-shaped, most of the desiccant will be about 1/2 to 1/2 of the container's capacity when used by protruding it on food etc. ! The result is that it collects only at the bottom of the container, creating a difference between the moisture absorption effect of the upper part and the moisture absorption effect of the bottom part, and when it expands, it also expands in the lateral direction, causing the moisture absorption effect of the breathable body that forms part of the container to increase. There were defects that could damage the breathable coating.

(Means for Solving the Problems) Therefore, the present invention provides, as a means for solving the problems of the conventional device, as illustrated in FIGS. 1 to 5.
This is a moisture absorber in which at least a part of a container 1 is formed of a gas permeable body 3, a desiccant 6 is filled in the container l, and the desiccant 6 absorbs moisture through the gas permeable body 3. At least two parts of the container body 2 are attached to the container body 2 excluding the breathable body 3.
Forming partitions II and 21 that partition into the above compartment IO,
Desiccant 6 is filled in each of the compartments IO.

(Function) According to the present invention, the desiccant 6 is evenly distributed in the container l by the above means, the moisture absorption effect is equalized, and the desiccant 6 is accumulated in a part of the container l and expands due to moisture absorption. The problem of damaging the container 1 is eliminated.

(Example) Referring to the drawings shown in FIGS. 1 to 5 below,
Moisture absorbers as preferred embodiments of the present invention will be described in detail.

First, a first embodiment shown in FIG. 1 will be described. In the figure, reference numeral 1 is a container of a moisture absorber, and 2 is a main part of the container L. It is a rectangular parallelepiped made of metal or synthetic resin, and one end 2a is tapered or pointed, and two of the four sides are opposite to each other. is a container body having an opening 2b, and an inner partition 11 that partitions the container body 2 into six compartments IO.
is integrally molded with the container body 2.

Reference numeral 13 designates an air-permeable film such as air-permeable paper, nonwoven fabric, felt, or porous film that is thermally welded, thermocompressed, or adhered (hereinafter simply referred to as adhesion) to one opening 2b of the container body 2; is the air-permeable coating 1 of the container body 2
A non-breathable coating such as a non-breathable film, resin film, glass, etc. is bonded to the other opening 2b on the opposite side to the bonded surface of 3, and the container I has a container main body 2, a breathable coating I3, and It consists of a non-breathable coating 14. 5 or 5- is a transparent body or a semi-transparent body in which a part of the air-impermeable coating 14 is made transparent or semi-transparent. 6 is a powder or granular desiccant such as silica gel or calcium chloride. 7 is an indicator printed or applied on the side of the transparent body 5 of the impermeable coating 14 facing the desiccant 6, and includes, for example, cobalt oxide, which changes color from red to blue upon absorption of moisture.

Therefore, the inner partition 1 has a notch 1 formed in a small uneven shape to prevent the desiccant 6 from transferring to other compartments IO on the surface in contact with the breathable coating 13'' and the non-breathable coating 14.
2a, which allows air to circulate between each compartment 10°10 and provides moisture permeability.

Then, a breathable coating I3 having the same shape as the opening 2b is adhered to one opening 2b of the container body 2 shown in FIG. Glue so that the indicator 7 is on the inner desiccant 6 side. In this way, the non-breathable coating +4 is disposed so as to be located farthest from the breathable coating M13c with the desiccant 6 interposed therebetween.

Thus, the desiccant 6 filled in each compartment 10 of the container l
The amount is initially about 1/2 to 1/4 of the volume of each compartment 10 of the container 1, taking into account the increase in volume due to moisture absorption.

When one end 2a of the tapered container main body 2 of the moisture absorber configured as described above is inserted into the dry food, the moisture in the air inside the bottle or wire is absorbed by the air permeable coating 13 into the container main body 2.
The food enters the container and is captured by the desiccant 6, leaving the food in a dry state, but at this time the container! is partitioned into six compartments lO, each of which is filled with desiccant 6, so that desiccant 6 accumulates at the bottom of container l and spreads between the top and bottom of container l, as in the case where compartment 10 does not exist. There is no difference in the moisture absorption effect in each compartment, and since the partition 11 is provided with a large number of notches 12a, each compartment t o,t .

The spaces between the compartments are in communication with each other and are moisture permeable, so that the moisture absorption effect of each compartment IO is further equalized. Note that the inner partition 11Ω notch 12a
is formed into irregularities smaller than the diameter of the desiccant 6, so
The desiccant 6 does not pass through the notch 12a and accumulate in the lower compartment lO, so that the moisture absorption effect is equalized between the upper and lower parts of the container l, and in consideration of the expansion of the desiccant 6,
Since the filling amount is determined, the container body 2, the breathable coating 13, the non-breathable coating 14, etc. will not be damaged.

When the moisture absorption ability of the desiccant 6 disappears, the indicator 7 facing the desiccant 6 changes color from red to blue due to moisture absorption, indicating that the moisture absorption ability has disappeared. It is visible from outside the container 1 through the transparent body 5 or semi-transparent body 5, and informs the consumer when it is time to replace the desiccant 6.

In the second embodiment shown in FIG. 2, instead of forming the small uneven notches 12a on the surface in contact with the breathable coating 11113 and the non-breathable coating 14 in the first embodiment, the desiccant 6 is placed in the partition 11. This embodiment has a large number of holes 12b with a smaller diameter than that of the first embodiment, and the other structure is the same as that of the first embodiment, and the operation is also the same, so the details will be omitted.

Next, in the third embodiment shown in FIG. 3, the shape of the container body 2 is the same as that of the first embodiment, but the container body 2 and the partition 11 are integrally formed of transparent resin. An indicator 7 is printed or applied on the inner surface at a position facing the desiccant 6 filled portion, and a gas permeable film 13 of the same shape is adhered to two opposing openings 2b of the rectangular parallelepiped.

In this case, partition! 1 is provided with an elongated slit 12c for keeping the humidity inside the container 1 uniform, but this slit 12c may not be provided.

With this structure, the moisture in the airtight container containing food will evenly enter the container body 2 through the breathable coatings 13 and 13 on the two sides, creating small uneven notches that provide moisture permeability to the inner partition 11. 12a, the small diameter hole 12b, or the slit 12c, the desiccant 6 absorbs moisture evenly. The disappearance of the moisture absorption ability of the desiccant 6 is visually recognized from the outer surface of the transparent container body 2 by the discoloration of the indicator 7.

- Furthermore, in the fourth embodiment shown in FIG. 4 and the fifth embodiment shown in FIG. 21 is molded integrally with the container body 2 using resin or molded separately and bonded, and each opening is covered with a breathable film! 3 and a non-breathable film 14, or the container body 2 is made transparent and a breathable film 13.13 is glued to both openings, and each compartment IO in the container 1 is filled with a desiccant 6. It is placed on top of food in a closed container containing food to absorb moisture. Then, the indicator 7 is printed or applied on the non-air permeable film 14 or the transparent container body 2 at a position facing the desiccant 6 filled part, and this embodiment has almost the same effect as the previous embodiment. This is what we do.

In each of the embodiments described above, the compartments 10 are divided into 6 compartments in the first to third embodiments and 12 compartments in the fourth and fifth embodiments, but the compartments 10 are limited to the above number. Needless to say, it is better if the number is at least 2 or more.

Further, in the first and second embodiments, the container l is composed of a container body 2, a breathable film 13, and a non-breathable film 14, and in the third embodiment, it is composed of a container body 2, a breathable film 13, and a fourth ,
In the fifth embodiment, the container I is made of a bent material or the latter, but the point is that at least a part of the container I is covered with the breathable film 1.
3 to absorb moisture through the breathable film 13.

In the above embodiments, the indicator 7 is mixed into the drying agent 6 in the form of powder or granules, or the indicator 7 is applied to the surface of small resin granules, or the indicator 7 is applied to the surface of a granular inorganic material. When the desiccant 6 reaches its limit of moisture absorption capacity, the indicating agent 7 changes color, and this discoloration can be prevented by making a part of the non-breathable film I4 transparent or by making the container body 2 transparent. It is also possible to form it so that it can be visually recognized from the outside of the container 1.

In addition, in the present invention, in addition to the breathable film 13 described in the above embodiments, breathable felt can also be used, so these are collectively referred to as the breathable body 3, and the non-breathable film 13 can also be used. Non-breathable materials other than 1.1 that can be used are collectively referred to as non-breathable material 4.

(Effects of the Invention) Since the present invention is constructed as described above, it has the following remarkable effects.

(1) According to the present invention, the desiccant 6 is evenly distributed in the container 1, the moisture absorption effect is equalized, and the desiccant 6 accumulates in a part of the container I and expands due to moisture absorption. This eliminates the problem of damaging the container l.

(2. If the embodiments described in Claims 2 and 3 are adopted, each of the plurality of compartments 10 will have the same moisture absorption conditions, and the moisture absorption effect will be further equalized and performance will be improved. , and the disadvantage that the desiccant 6 passes through the partition 11.21 and accumulates in a part of the container i is further prevented.

(4) By implementing the embodiment described in claim 4, defects in which the container 1 is damaged due to volumetric expansion due to moisture absorption of the desiccant 6 can be prevented.

(5) According to the embodiment described in claim 5, if the indicator 7 is provided at a position facing the desiccant 6 filling part on the inner surface of the container body 2, the transparent container body 2 Through this, the discoloration of the indicator 7 can be visually recognized from outside the container 1, and the consumer can easily know when to replace the desiccant 6.
