Description

  The present invention relates to a deodorizing tool that can be used for household and commercial refrigerators, sinks, shoe boxes, and the like.

  Since various kinds of food are stored in the refrigerator, various bad odors may be generated. In addition, a unique odor is often generated even in a sink or a clog box. As deodorizing tools used in these places, activated carbon box-packed ones or gel-filled ones with deodorizing substances such as plant extracts and surfactants are known. However, although it is not so common, there are also known a type in which a sheet-like deodorizing tool is attached or laid in the cabinet (see Patent Document 1) and a type in which malodor is oxidized and decomposed with sodium hypochlorite. ing. Moreover, in the case of a refrigerator, there are some in which a deodorizing device using activated carbon or the like is built in the cabinet.

A variety of deodorizing tools have been proposed and commercialized in this way, but in a deodorizing tool in which a deodorizing agent is stored in a container and used, such as activated carbon type, gel type, and oxidative decomposition type, which are used relatively frequently, There is a disadvantage that the installation place of the deodorizing tool is unexpectedly large and is likely to get in the way. Especially in refrigerators where the capacity that can be stored is limited, the deodorizing tool has a drawback in that the capacity that can be stored for food is reduced. On the other hand, sheet-shaped deodorizers have the advantage of not substantially reducing the capacity that can be stored in the refrigerator. However, in the case of deodorizers that are laid on storage shelves, block the passage of cold air provided on the storage shelves. Therefore, there was a problem that the circulation of the cold air in the warehouse was impaired. In addition, deodorizing tools of the type that are attached to the wall also have problems such as double-sided tape required for attachment, and adhesive residue after removal or contact with tableware or the like. Furthermore, the type built into the refrigerator has a drawback that it cannot be replaced for about 10 years when the refrigerator is replaced. When the years have passed since the start of use, the above-mentioned shelf-type deodorizing tool is used in combination. Is common.

  An object of the present invention is to provide a deodorizing tool that does not particularly require a new place for installing the deodorizing tool. For example, it is an object of the present invention to provide a deodorizing tool that can be installed without reducing the storage capacity of food even in a refrigerator and without impairing the ventilation in a cabinet necessary to absorb bad odors. .

  The present invention is a deodorizing tool comprising a cork block containing a granular deodorizing agent and having one or more recessed portions or vertically penetrating portions opened in the vertical direction. Here, the cork block preferably has four or six side surfaces, and each side surface is preferably substantially rectangular. Moreover, it is preferable that the said cork block is a substantially rectangular parallelepiped or a substantially hexagonal column. Moreover, it is preferable that the said recessed part or a penetration part is a truncated cone shape which has a central axis of a perpendicular direction and spreads upwards. Moreover, it is preferable that the shape of the said recessed part or the penetration part is what was match | combined with the external shape of the container accommodated. Moreover, it is preferable that the number of the said recessed part or penetration part is 1 or an even number. The granular deodorizer is preferably activated carbon.

  A dead space that has been overlooked without being used in the past can be used effectively, so no new space or place is required. For example, it can be installed in a refrigerator with little reduction in the food storage capacity and without impairing the ventilation in the cabinet. Moreover, since the porous deodorizing tool covers the periphery of the container, it is possible to simultaneously exhibit the cold-retaining action of a refrigerated container such as ice cream and the absorption of moisture condensed on the container surface.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The deodorizing tool of this invention consists of a cork block containing a granular deodorizing agent. Cork is made up of the cork part inside the cork bark, and is composed of 45% suberin, 27% lignin, 6% tannin, 5% wax, and cellulose polysaccharides and ash. Although the cork itself does not have a large air permeability, a gap between the cork particles is generated by once crushing and then forming into a block. For this reason, the air permeability is very good compared to simple wood and plastic. Therefore, malodor can easily penetrate into the cork block, and even if a granular deodorant is embedded in the cork block, it is possible to efficiently contribute to deodorization. Also, the shape can be freely made by molding after mixing with the binder resin.

  As the granular deodorizing agent used for the deodorizing tool, activated carbon, the deodorizing agent described in Patent Document 1 and other known deodorizing agents can be used, and one kind may be used, or a plurality of documents may be mixed and used. From the viewpoint of ease of use and safety, it is preferable to use granular activated carbon. The granular activated carbon may be in the form of particles or finer powder, but it is preferable to use a powdered activated carbon from the viewpoint of increasing the surface area as much as possible. The activated carbon may be derived from any of coal, coconut shell, and wood, and is not particularly limited. Cork can be discarded as combustible waste when it is discarded after use. Further, the content of the activated carbon may be appropriately adjusted within a range in which a necessary deodorizing capacity is satisfied and a cork block can be manufactured, and is within a range of 5% by mass to 40% by mass with respect to cork. preferable. More preferably, it exists in the range of 10 mass% or more and 30 mass% or less.

  As a cork adhesive or binder, a polyurethane-based or natural resin-based known adhesive or resin binder may be used. From the viewpoint of safety, it is preferable to use a natural resin binder. Examples of the natural resin binder include NP-0381 manufactured by Auro, Germany. The amount of binder used is a mass ratio of 1/20 to 1/2 with respect to the total mass of cork and granular deodorant in order to maintain the strength of the cork block and not to lose the porosity of the cork. Is preferably used within the range of 1/10 to 1/4.

  The cork block serving as a deodorizing tool has one or both of one or more concave portions opened in the vertical direction and one or more through portions in the vertical direction. The concave portion or the through portion is for fitting and fixing the container in the inside from the vertically upper side to the lower side. The shape of the concave portion or the penetrating portion may be a cylindrical shape or a quadrangular prism, but is adapted to the outer shape of the container inserted into the concave portion or the penetrating portion. Many of the general containers have a frustoconical shape with the top expanded and the skirt narrowed, so the concave or penetrating part of the cork block also has a hem with the top expanded to match the general side shape of such containers. It is preferable to use a truncated cone shape. Regardless of the shape of the container, the concave portion is provided so that the container can be fitted downward from above in accordance with the container. By fixing the container in the cork block as described above, in other words, by arranging the cork block along the outer surface of the container, a new place for installing the deodorizing tool is not necessary. An example of such a cork block is shown in FIG.

  The cork block 1 shown in FIG. 1 has a substantially rectangular parallelepiped shape including four substantially rectangular side surfaces 2 and 3 and a substantially rectangular upper surface 8 and a bottom surface 7, and the upper surface 8 has a central axis in the vertical direction. A concave portion 10 is provided that includes a side surface 5 having a truncated cone-shaped side surface with an upper portion expanded and a lower portion narrowed, and a bottom surface 6. The container is fixed to the cork block (deodorizing tool) by fitting the bottom of an arbitrary container into the recess 10 from above. Here, the fact that the side surface is substantially rectangular means that the geometrical shape does not have to be a strict rectangle, and the two facing sides do not have to be strictly parallel, and the straight line of the side is slightly bent. good. Moreover, the shape close | similar to the trapezoid in which the bottom was somewhat narrowed may be sufficient.

  Note that the vertical and horizontal dimensions of the cork block 1 are as small as possible within a range where the container can be accommodated and the strength of the cork block can be used to withstand use. To preferred. Specifically, on the upper surface 8, it is preferable that the shortest straight line distance between the concave portion or the penetrating portion and each of the four side surfaces is as small as the cork strength allows. For example, if the container has a truncated conical shape with a flange on the outside of the upper end, the upper surface should be approximately square, and the same length as the flange outer diameter of the container should be the length of one side of the approximately square. good.

  In general, plastic containers used in refrigerators, food storages, etc. are divided into a container part and a lid, and the outer edge part above the bottom part of the container part is used to improve the fit between the lid and the container part. Projects outward. For this reason, a dead space is generated between other adjacent containers and wall surfaces. The deodorizing tool is molded in a shape along the outer periphery of the storage container so as to fill the dead space, and is installed in the dead space in the refrigerator and food storage, thus reducing the storage space. The deodorizer can be installed without any problems. Similarly, you may make it a donut shape etc. which put a deodorizing tool on the neck of a bottle.

  Moreover, when taking out the container fitted in the deodorizing tool from the refrigerator, the cork block of the deodorizing tool serves as a cold container by taking out the deodorizing tool, and the temperature change of the container contents can be delayed. Furthermore, at this time, if there is no deodorizing tool, water droplets that should be generated by condensation on the container surface can be prevented. In addition, plastic containers are often seen as cheap, and it may be difficult to put them on the table as they are. However, it is possible to produce a high-class feeling by covering with cork, and it is possible to leave the plastic container on the table as it is.

  If the storage container used is made of a material that can withstand temperatures such as a range, the food can be heated while still in the storage container, and if the storage container is wrapped in a cork block, the temperature is maintained. Can have sex. Moreover, the malodor adsorbed by the activated carbon can be desorbed simultaneously with heating the cork containing activated carbon in the range. That is, the activated carbon can be reactivated at the same time when heating in the range.

  The deodorizing tool may have two or more vertically opened recesses or vertical penetrating parts, but preferably one or an even number may be present in one deodorizing tool. The reason why the number of the recesses is an even number is to make the cork block easy to manufacture and to make the area necessary for installing the deodorizing device as small as possible. In this way, it is also possible to make a deodorizing tool by providing a plurality of recesses or penetrating parts and storing a plurality of storage containers at the same time. Thereby, when accommodating in a refrigerator etc., the container of several foodstuffs can be accommodated simultaneously. For example, it will be possible to store raccoon and Fukujinzuke containers at the same time, making it easier to organize and organize food.

  An example of a deodorizing tool provided with six recesses is shown in FIG. The deodorizing tool 20 of FIG. 2 has six recesses 21 formed of a truncated cone side surface 22 and a bottom surface 23 on the upper surface 21 so that six containers of the same size and shape can be fitted simultaneously. Is provided. By providing a plurality of recesses in this way, it becomes possible to handle a group of containers used in a set at the time of use, such as a seasoning set, for example.

  The side surface of the cork block is preferably a combination of a plurality of substantially rectangular shapes. More preferably, the number of substantially vertical side surfaces is four or six so that the cork block is a substantially rectangular parallelepiped or a substantially hexagonal column. By simplifying the shape of the side as described above, the manufacture of the cork block is simplified, and a deodorizing tool having a large deodorizing capacity can be obtained for the area necessary for installing the deodorizing tool. An example of a deodorizing tool having six side surfaces is shown in FIG. The deodorizing tool 30 in FIG. 3 has a substantially hexagonal upper surface 32 and six substantially rectangular side surfaces 33 corresponding thereto. In addition, you may process so that the corner | angular part of the connection part of each plane may be rounded. Moreover, you may make it provide the pattern of a groove | channel etc. for making the surface of a cork block increase the surface area which affects deodorizing ability. Further, a briquette-like hole may be formed in the cork block to increase the surface area of the cork block.

  Next, the manufacturing method of a deodorizing tool is demonstrated. The cork block that makes up the deodorizing tool may be cut out the desired shape from the cork raw material obtained by peeling the bark of cork oak and drying, and a granular deodorant may be attached to the surface, but cork is effectively used In order to obtain an arbitrary shape of the cork block, the cork raw material is once crushed by a granulator based on the usual method for producing a cork block, and then the obtained crushed material is mixed with a binder and a granular deodorant. Then, it is desirable to stir and then press mold to form the desired shape.

  Specifically, a cork pulverized product and powdered activated carbon or granular activated carbon are mixed and compression-molded together with a binder resin to make a deodorizing tool composed of a cork block. At that time, one or more recesses or penetrating portions that match the size of the tableware or storage container are provided, and the tableware or storage container is inserted into the recess or penetration portion for use. When a cork block is used, a part of the crushed cork is colored or partially baked and colored, mixed with normal crushed cork, and hot-compressed with a binder resin to give decorativeness. It may be a certain cork block. In addition, decorations based on characters and designs may be baked on the surface of the cork block with a baking cake or the like.

Hereinafter, the present invention will be described more specifically with reference to examples. Note that the present invention can be modified in various ways within the scope thereof, and is not limited to the following specific modes.
[Experimental Example 1]

  100 parts of crushed cork grains, 40 parts of powdered cork, 20 parts of granular activated carbon, 20 parts of powdered activated carbon and 30 parts of resin binder (urethane resin) are mixed and stirred, compression molded, and a 85 mm × 85 mm × 40 mm rectangular parallelepiped deodorizer I made a sample.

Using this deodorizing tool sample, a deodorization test was conducted as follows. First, a cube having a side of 4 cm was cut out from the sample of the deodorizer, and placed at the center of the bottom of a 20-liter plastic tank having a sample inlet at the top and a measurement hole with a diameter of about 1 cm at the center of the side. There, the air whose hydrogen sulfide concentration was adjusted to 50 ppm was poured at a rate of about 500 cc per second for 1 minute, and the internal hydrogen sulfide concentration was adjusted to 50 ppm. In this state, the polytank was sealed with a lid and a silicone rubber stopper, and the hydrogen sulfide concentration after 8 hours was measured with a detector tube. The evaluation results are shown in Table 1. The evaluation result is an average of three points. Good deodorization performance was shown.
[Comparative Experiment Example 1]

A deodorization test was conducted in the same manner as in Experimental Example 1, except that the deodorizer sample was not used. The evaluation results are shown in Table 1. The hydrogen sulfide concentration hardly changed.
[Experiment 2]

A deodorization test was conducted in the same manner as in Experimental Example 1 except that the ammonia concentration was 200 ppm instead of 50 ppm of hydrogen sulfide. The evaluation results are shown in Table 1. Good deodorization performance was shown.
[Comparative Experiment Example 1]

A deodorization test was conducted in the same manner as in Experimental Example 2 except that the deodorizer sample was not used. The evaluation results are shown in Table 1. Although the ammonia concentration decreased slightly, the change was slight.
[Example 1]

  With the same composition and method as in Experimental Example 1, the upper surface is a substantially square shape with a side length of 90 mm and a height of 90 mm. From the upper surface downward, the upper base diameter is 85 mm and the lower base diameter is A frustoconical concave portion having a depth of 75 mm and a depth of 80 mm was provided to produce a deodorizing tool having the same shape as that shown in FIG.

  A storage container having an outer diameter of 72 mm at the bottom, an outermost diameter of 90 mm at the upper end, and a height of 86 mm was inserted into the recess of the deodorizing tool from the bottom. A flange having a height of 6 mm and a thickness of 4 mm in diameter is provided at the upper end of the storage container. The storage container fits perfectly into the recess, and only the flange at the container end protrudes from the upper surface of the deodorizing tool. Since the maximum width of the storage container was 90 mm and the maximum width of the deodorizing tool was 90 mm, it was the same size as the place required for installation of the storage container. In addition, when the storage container was compared to the same storage container except that it was poured into water at 0 ° C containing ice to a height of 70% and the deodorizer was not used, the heat retention when using the deodorizer (coldness) The result was high and good.

It is (1) front view, (2) top view, (3) perspective view which showed an example of the deodorizing tool. It is the perspective view which showed the other example of the deodorizing tool. It is the perspective view which showed the other example of the deodorizing tool.
