Abstract

<P>PROBLEM TO BE SOLVED: To provide a case in which fragrance can be kept for a long time. <P>SOLUTION: A fragrant ingredient of an even highly volatile fragrant material can be enclosed for a long time by putting it in a micro capsule. Since the fragrant ingredient oozes out of a shell of the micro capsule little by little in this instance, fragrance can be gently emitted for a long time. The micro capsule with the fragrant material enclosed is applied to an internal surface of the case and thus attached in the case. Therefore, the case which can keep the fragrance inside the case for a long time can be provided. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a case that can hold a scent in the case for a long time.

  Conventionally, as a method for sealing and storing scented products and scent components, sealing is performed by interposing an elastic member having a low gas permeability between a polyethylene terephthalate container and a lid as disclosed in Patent Document 1. How to do is known.

    (Patent Document 1) Japanese Patent Application Laid-Open No. 2005-8232

  Most of the scent components volatilize within 12 hours, and cannot be stored for a long time unless sealed. Therefore, it is necessary to use a case that can be sealed, such as the container of Patent Document 1. However, when the container of Patent Document 1 is used in a case together with a scent component, especially in the case of a large container, since the opening becomes large, it becomes difficult to seal the container, and the scent component is retained. Can not do it. In addition, in order to seal the container, there is a problem that when a small container is used, there is no storage thing or it must be put in small portions.

  The gist of the present invention is a case in which a microcapsule containing at least a fragrance is attached to the inner surface of the case.

  A microcapsule is a fine particle of 1 micron to several hundreds of micron, and another substance is enclosed inside. Even if it is a highly volatile fragrance | flavor, a scent component can be confined for a long period of time by putting in this microcapsule inside. In this case, since the fragrance component oozes out little by little from the outer shell of the microcapsule, the fragrance can be continuously released for a long time. In addition, when it is desired to increase the scent, the amount of scent released can be increased by deforming and destroying the microcapsule by a method such as friction. By applying a fragrance encapsulated in the microcapsule to the inner surface of the case, the scent can be held inside the case for a long period of time without sealing the case by the method as in Patent Document 1. .

  An example will be described based on the drawings.

<Example 1>
FIG. 1 is a perspective view of a case in which a paper inner box 2 is covered with a paper outer box 1 serving as a lid. The inner box 2 is a box for storing paints and crayons. The inner box 2 can be provided with a partition or a tray in order to align the paint and crayons. The outer box 1 is a box that covers the inner box 2 and serves as a lid. The dimensions are such that there is no backlash when the inner box 2 is covered with the outer box 1 and can be removed freely. As an example of a position where a microcapsule containing a fragrance is attached, the inside 3 of the ceiling portion of the outer box 1 is shown by dots. The adhesion amount of the microcapsules containing the fragrance is about 0.01 to 0.5 gram in the whole case. A microcapsule containing 0.5 g of a jasmine fragrance as a fragrance was allowed to stand at 40 ° C. for 1 month, and the scent was confirmed by sensory sense.

<Example 2>
FIG. 3 is a perspective view of a case in which a paper inner box 2 that can be inserted and removed is inserted into a paper sleeve-type outer box 4. FIG. 4 is a component diagram in which the sleeve-type outer box 4 of FIG. 3 is developed. The sleeve type outer box 4 is a cylindrical part for inserting the inner box 2 into a lid. The sizes of the inner box 2 and the sleeve type outer box 4 are not loose and are in contact with each other so that they can be removed freely. As an example, a position where a microcapsule containing a fragrance is attached is shown in FIG. 4 by dots on the inside 5 of the ceiling portion of the sleeve-type outer box 4. The adhesion amount of the microcapsules containing the fragrance is about 0.01 to 0.5 gram in the whole case. A microcapsule containing 0.3 g of a jasmine fragrance as a fragrance was allowed to stand at 40 ° C. for 1 month, and the scent was confirmed by sensuality.

<Example 3>
FIG. 5 shows a case in which a polypropylene paint, a crayon housing 6 and a polypropylene lid 7 are connected by a polypropylene hinge 8. The lid 7, the paint, and the crayon housing 6 are not opened during storage by a method such as providing a fitting portion or fixing with a hook. The inside 9 of the ceiling part of the lid 6 is indicated by dots, taking as an example the position where the microcapsules containing the fragrance are attached. The adhesion amount of the microcapsules containing the fragrance is about 0.01 to 0.5 gram in the whole case. A microcapsule containing jasmine fragrance contained as a fragrance was allowed to stand at 40 ° C. for 1 month, and the scent was confirmed by sensuality.

<Comparative Example 1>
The same shape as in Fig. 1, 0.05 grams of jasmine fragrance is placed in a styrene inner box 2 and then 0.5 mm thick butyl rubber is placed on the entire inner surface of the ceiling of the styrene outer box 1. Covered and left at 40 ° C. for 1 month to check the scent by sensuality.

The results of Examples 1 to 3 and Comparative Example 1 are shown in Table 1. “◯” in the table indicates that the scent is felt, and “x” indicates that the scent is not felt.
