BACKGROUND OF THE INVENTION
The present invention relates to a package and a dehumidifier containing a dehumidifying agent, a fragrance, a deodorizing agent, a deodorizing agent, and the like.
[0002]
[Prior art]
Conventionally, a dehumidifier has been used to remove moisture.
[0003]
This dehumidifier was composed of a plastic container containing a dehumidifying agent, and the opening of the plastic container was covered with a gas permeable sheet. On this air-permeable sheet, a non-air-permeable sheet is laminated so that moisture absorption by the dehumidifying agent before the start of use can be prevented.
[0004]
In addition, a bag-type dehumidifier with a dehumidifying agent enclosed in a bag body, the entire surface or part of which is formed of a gas-permeable sheet, or a refill type dehumidifier that uses a plastic molded container to refill only the dehumidifying agent. The vessel is known. These bag-shaped dehumidifiers (refillers) and refill dehumidifiers are packed in a non-air-permeable package at the time of distribution to prevent moisture absorption by the dehumidifier before use. The package was opened and only the drug inside was used.
[0005]
[Problems to be solved by the invention]
However, in the dehumidifier such as the former, the sheet having a size set to a large area is discarded as garbage in order to increase moisture absorption efficiency because of the structure in which the non-permeable sheet is peeled off at the start of use. It will be. At this time, the non-permeable sheet is easy to peel off, and the permeable sheet laminated on the sheet must be prevented from peeling off. For this reason, both had to be fixed with different adhesive strengths, resulting in an increase in manufacturing costs.
[0006]
In the latter case, the packaging body is discarded as garbage during use, and there is a problem that the amount of garbage increases. In addition, the packaging process is a separate process from the product manufacturing process, which increases the manufacturing cost. The problems related to such a conventional dehumidifying agent are the same for fragrances, deodorants, insect repellents, oxygen scavengers, and the like whose state changes in response to contact with gas.
[0007]
The present invention has been made in view of these conventional problems, and provides a package and a dehumidifier that can reduce the amount of dust and prevent changes in contents before use while reducing costs. It is intended to do.
[0008]
[Means for Solving the Problems]
  In order to solve the above-mentioned problem, the dehumidifier according to claim 1 of the present invention is a dehumidifier having a package body containing a dehumidifying agent that absorbs moisture in the air, and blocks the permeation of moisture in the air A non-air-permeable sheet that forms a sealed space, and an air-permeable sheet that allows permeation of moisture in the air inside the sealed space, and an opening that is opened during use. A package body that is partitioned into a space; a container body that houses the package body; and a lid body that covers the upper opening of the container body and has a vent hole.The air-permeable sheet is set to a size that can be arranged along the inner surface of the lid body provided with the vent hole,Fits inside the container body on the lidAnd saidA position restricting part is provided to restrict the position of the air permeable sheet placed inside.On the other hand, the area of the non-permeable sheet made of a non-permeable film is set wider than the permeable sheet, and the non-permeable sheet is formed in the accommodation space formed by the non-permeable sheet in the expanded state. It is configured to be able to store moisture, and the accommodating space is disposed in the lower portion of the air-permeable sheet disposed along the lid body with the lid body mounted on the container body. did.

  That is, a dehumidifying agent that absorbs moisture in the air is a non-air permeable material that blocks air permeation.SheetIt is accommodated in the sealed space formed by. For this reason, contact with external air and the said dehumidifier is prevented.
[0017]
  The sealed space is air permeable.SheetThe storage space in which the dehumidifying agent is stored is separated from the opening space that is opened during use. For this reason, careless scattering of the dehumidifying agent is prevented when the opening space is opened. At this time, the air permeabilitySheetIn order to allow permeation of air, contact between the dehumidifying agent and external air is started.
In addition, the packaging body is set so that the air-permeable sheet faces the upper opening side of the container body in order to efficiently exhibit the hygroscopic force. At this time, the upper opening is covered with a lid provided with a vent, so that the air-permeable sheet is prevented from being damaged due to the fall of foreign matter on the dehumidifier.
Furthermore, the dehumidifying agent is disposed in the vicinity of the upper opening of the container body in a state where the packaging body is accommodated in the container body.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
[0030]
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing a packaging body 1 according to the present embodiment. As shown in FIG. 2, the packaging body 1 includes a container body 2 that houses the packaging body 1, and the container body 2. A dehumidifier 5 is configured by the lid 4 that covers the upper opening 3 and includes a vent (not shown).
[0031]
As shown in FIG. 1, the packaging body 1 includes a bag body 11 that is a non-air-permeable portion that blocks permeation of air as a gas, and the bag body 11 has a rectangular non-permeable shape. The water-permeable films 12 and 12 are formed by joining at the bottom and left and right sides. A microporous film 14 as a sheet body, which is an air permeable portion that allows permeation of air as a gas, is fixed to the inner side surface of the bag body 11 on the opening 13 side by heat seal portions 14a and 14a. . As a result, a storage space 15 is formed in the lower part of the microporous film 14, and a large number of granular dehumidifying agents 16 that absorb moisture in the air are stored in the storage space 15. Yes.
[0032]
The microporous film 14 is bent in a V-shape at the center of the bag body 11 and is configured so that the bag body 11 can be developed in the lateral direction.
[0033]
The bag body 11 is closed with the edge and lower edge of the opening 13 joined together by heat seal portions 13a and 13b, and the air flow is blocked inside the bag 11. A sealed space 21 is formed. An opening space 23 that is opened during use is formed between the upper closing portion 22 and the microporous film 14, and the sealed space 21 is separated from the housing space 15 by the microporous film 14. It is partitioned into the opening space 23.
[0034]
As shown in FIG. 2, the container body 2 is made of plastic, and is configured so that the upper opening 3 can be held with the peripheral wall 4 a of the lid body 4 fitted therein. . As shown in FIGS. 2 (b) to 2 (c), the peripheral wall 4a is set to a dimension capable of regulating the position in a state where the microporous film 14 of the package 1 is disposed on the inner side.
[0035]
Further, the volume of the container body 2 is equal to or greater than the volume of the contents composed of the dehumidifying agents 16,... And the moisture absorbed in the state where the moisture absorption by the dehumidifying agents 16,. Is set to
[0036]
Here, the case where calcium chloride is used as the dehumidifying agent 16,... Will be described as an example.
[0037]
That is, when calcium chloride dihydrate: 190 g is filled into a container volume: 620 ml and moisture is absorbed at 40 ° C., humidity 90%, and 2 months, the water absorption is almost saturated. The moisture absorption amount at this time was 540 g.
[0038]
Calcium chloride dihydrate absorbs 2.84 times the water, so the weight at this time is
[0039]
{Weight of calcium chloride dihydrate (g) x (1 + 2.84)} g (Formula A)
[0040]
It becomes.
[0041]
When converted to volume,
[0042]
{Weight of calcium chloride dihydrate (g) x (0.42 + 2.84)} ml (Formula B)
[0043]
It becomes.
[0044]
* 0.42 indicates increase in capacity when calcium chloride dihydrate is dissolved in water
[0045]
The container volume (ml) required for the product is determined by the amount (g) of calcium chloride dihydrate. It is simply “calcium chloride dihydrate weight (g) × 3 to 4 volume (ml)”, but the weight cannot simply be replaced with volume.
[0046]
For this reason, the amount of calcium chloride dihydrate may be measured with a true volume, but the actual calcium chloride dihydrate is granular, including the gap between the grains and the air contained in the grains, It is difficult to easily determine the true volume. As the method, after pulverization, it is hardened by pressurization. Melts at several hundred degrees Celsius. Dissolve a certain amount in water and measure the increased volume. Etc.
[0047]
Note that the value obtained by dissolving a certain amount in water and calculating the increased volume is 0.42 as described above, and at present, this is used as the specific gravity.
[0048]
On the other hand, the weight (g) of calcium chloride dihydrate can be easily obtained, and the volume can be calculated by dividing this by the specific gravity (weight / volume). And conversion. That is, in the above-described (Formula B), it includes specific gravity, and it is assumed that weight and volume are converted.
[0049]
From these,
[0050]
{Calcium chloride dihydrate weight (g) / specific gravity (g / ml) × 7-10 = container volume} (Formula C)
[0051]
It becomes. (The specific gravity of calcium chloride dihydrate is 2.38 (reciprocal of 0.42)) When this equation is simplified, it becomes (Equation B).
[0052]
Here, if the calcium chloride dihydrate is obtained by volume from the beginning, it is 42 ml = 100 g. However, the expression 42 ml calcium chloride dihydrate requires an attention because it imagines the volume of the granular material. .
[0053]
When the container volume is calculated by this method, it becomes “a volume that is 7 to 10 times the volume of calcium chloride dihydrate”, and in the present embodiment, the volume calculated from this is adopted as the volume of the container body 2. did.
[0054]
And this container body 2 is in the state which accommodated the said package 1 cut | disconnected in the said opening space 23, and the said dehumidification chemical | medical agent 16, ... is located in the said upper opening part 3 vicinity of the said container body 2. FIG. It is set to such a depth.
[0055]
In the present embodiment according to the above configuration, the dehumidifying agent 16 that absorbs moisture in the air is sealed in the bag 11 formed by the non-permeable films 12 and 12 that block the permeation of air. It is accommodated in the space 21. For this reason, a contact with external air and the said dehumidification chemical | medical agent 16, ... can be prevented. Therefore, before the start of use, moisture absorption by the dehumidifying chemicals 16 can be prevented.
[0056]
When the dehumidifier 5 is used, as shown by a broken line in FIG. 1, the upper portion of the packaging body 1 is cut with scissors or the like to open the sealed space 21. At this time, the accommodating space 15 that accommodates the dehumidifying agents 16 is separated from the open space 23 by the microporous film 14. For this reason, in the state which opened this opening space 23, careless scattering of the said dehumidifying chemical | medical agent 16 ... can be prevented. And since this microporous film 14 accept | permits permeation | transmission of air, it can start the contact with the said dehumidification chemical | medical agent 16, ... and external air.
[0057]
And at the time of opening, since it is only necessary to cut and open the opening space 23 with scissors, for moisture absorption efficiency, the non-permeable sheet on the permeable sheet set to a large area must be peeled off, The amount of dust can be reduced as compared with the conventional case where the non-air-permeable sheet is discarded as dust. In addition, the non-permeable sheet laminated on the permeable sheet must be set to be more easily peeled off than the permeable sheet, and compared to the conventional case where both must be fixed with different adhesive strengths. Cost can be reduced. Moreover, since it is not necessary to wrap with a non-air-permeable packaging body unlike the conventional bag-shaped dehumidifying agent (vessel) or the dehumidifying agent for refilling, the amount of garbage can be suppressed and the manufacturing cost can be reduced.
[0058]
Next, the opening part of the bag 11 cut with scissors is expanded in the lateral direction. At this time, the microporous film 14 is bent in a V shape at the center of the bag body 11, and is configured so that the bag body 11 can be developed in the lateral direction. For this reason, the area which the said microporous film 14 which influences moisture absorption efficiency occupies can be increased.
[0059]
Then, as shown in FIG. 2B, the microporous film 14 is set on the lid body 4 in a state of facing the inverted lid body 4. At this time, the dehumidifying agents 16 in the accommodation space 15 fall on the developed microporous film. On the lid 4, as shown in FIG. 2 (c), after the inverted container body 2 is fitted into the peripheral wall 4 a, the dehumidifier is erected as shown in FIG. 2 (d). Complete 5. When the bag body 11 is manufactured, if the amount of air in the accommodation space 15 is reduced, the dehumidifying agent 16,... Will remain in the opening of the dehumidifier 5 even after the dehumidifier 5 is upright. Can be located nearby. Further, the height of the bag body 11 is made higher than the height of the container body 2, and the lower portion of the bag body is bent by the container body 2, so that the dehumidifying chemicals 16,. Can be located.
[0060]
By assembling in this way, the packaging body 1 housed in the container body 2 is arranged without the microporous film 14 being forcibly developed and easily closed, and the microporous film 14 and Since the dehumidifying agent is located near (in the vicinity of) the upper opening 3 of the container body 2, the moisture absorption efficiency is further improved. Further, since the packaging body does not interfere with the fitting portion between the container and the lid, the container and the lid can be reliably fitted.
[0061]
Moreover, since the upper opening 3 of the container body 2 in which the microporous film 14 is disposed is covered with the lid body 4 having a vent hole (not shown), it is caused by the fall of foreign matter on the dehumidifier 5 or the like. Damage to the microporous film 14 can be prevented. Thereby, the outflow of the contents such as the dehumidifying chemicals 16... Can be prevented.
[0062]
Further, the volume of the container body 2 is set to be equal to or greater than the volume of the content composed of the dehumidifying agent 16,... And the moisture absorbed in a state where moisture absorption by the dehumidifying agent 16,. ing. For this reason, the outflow of the water | moisture content stored in the package 1 after dehumidification to the exterior can be prevented.
[0063]
On the other hand, when manufacturing the package 1, the dehumidifying agents 16,... Can be accommodated in the package 1 by putting the dehumidifying agents 16,. . And the said bag body 11 can be sealed by joining the said bag body 11 in the opening edge side from the said microporous film 14 provided in the said bag body 11. FIG. Thus, since the package 1 can be manufactured by a simple process, the manufacturing process can be simplified.

【The invention's effect】
  As described above, the claim 1 of the present inventionDehumidifierIn that,By storing the dehumidifying agent that absorbs moisture in the air in a sealed space formed by a non-permeable sheet that blocks air permeation, contact with external air can be prevented. Therefore, moisture absorption by the dehumidifying agent can be prevented before the start of use.
[0121]
  In use, the sealed space is opened. At this time, the housing space containing the dehumidifying agent is the air permeability.SheetTherefore, it is separated from the opening space that is opened during use. For this reason, in the state which opened this opening space, the careless scattering of the said dehumidifying agent can be prevented. And this air permeabilitySheetCan permit the permeation of air, so that contact between the dehumidifying agent and external air can be initiated.
[0122]
And when opening, it is only necessary to open the opening space, the moisture-permeable sheet has to peel off the non-permeable sheet on the permeable sheet set to a large area. As compared with the conventional case where it is discarded, the amount of garbage can be suppressed. In addition, the non-permeable sheet laminated on the permeable sheet must be set to be more easily peeled off than the permeable sheet, and compared to the conventional case where both must be fixed with different adhesive strengths. Cost can be reduced.
[0123]
  Moreover, since it is not necessary to wrap with a non-air-permeable packaging body like the conventional bag-shaped dehumidifying agent (vessel) and the dehumidifying agent for refilling, the amount of garbage can be suppressed and the manufacturing cost can be reduced. In this embodiment, the non-permeable film is used as the non-permeable sheet. However, a non-permeable molded container may be used, and the peripheral edge of the molded container may be pseudo-bonded and peeled off during use.
Further, the packaging body is set so that the air-permeable sheet faces the upper opening side of the container body in order to efficiently exhibit the hygroscopic force. Here, since the upper opening is covered with a lid body provided with a vent hole, it is possible to prevent the air-permeable sheet from being damaged due to the fall of foreign matter on the dehumidifier. Thereby, the outflow of contents, such as a dehumidifying agent, to the exterior can be prevented. The air-permeable sheet of the package is forcibly deployed and disposed without being easily closed, and since the air-permeable sheet and the dehumidifying agent are located near (in the vicinity of) the upper opening of the container body, Moisture absorption efficiency is improved.
In addition, a dehumidifying agent can be disposed in the vicinity of the upper opening of the container body in a state where the packaging body is accommodated in the container body. Therefore, compared with the case where the said dehumidifying agent is arrange | positioned at the bottom part side from the said upper opening part, moisture absorption efficiency can be improved.
And the position control part which position-controls in the state which arrange | positioned the said air permeable sheet of the said packaging body inside was provided in the said cover body while being fitted in the said upper opening part of the said container body. Therefore, since the packaging body does not interfere with the fitting portion between the container and the lid, the container and the lid can be reliably fitted.
[0124]
  And claims2In the dehumidifier, the non-air-permeableSheetThe dehumidifying agent can be accommodated in a package by introducing the dehumidifying agent into a bag made of the above. And the said provided in the said bag bodyAir permeable sheetThe bag body can be sealed by joining the bag body on the opening edge side. Thus, since a package can be manufactured by a simple process, the manufacturing process can be simplified.
[0125]
  Claims3In the dehumidifier, since the air-permeable sheet is joined in a state of facing, the air-permeable sheet that allows permeation of air can be sealed in a state of being disposed inside.
[0130]
  in addition, Claims4In the dehumidifier, the lid is provided with a position restricting portion for restricting the position in a state where the air-permeable sheet of the packaging body is disposed inside, and the upper opening of the container body is disposed outside the position restricting portion. A peripheral wall that is externally fitted to the part was provided.
[0131]
With such a simple structure, the container body and the lid body can be configured.
