Description

  The present invention relates to a package using a foaming agent that foams and dissolves when placed in hot water or water as a packaging material.

  A person who wants to give a gift to a family, lover, friend, etc., chooses a gift in consideration of the other party's preferences. The gifts thus selected are stored in a box and further wrapped with wrapping paper or the like. The person who is given the present looks forward to what kind of gift it is, opens the package, rejoices that the giver has thought about his taste, and the affection of both parties increases. Here, the unexpectedness of the package that further enhances the expectation and unexpectedness of the gift is also important.

  In recent years, as an unexpected package, a product using a foaming bath agent (foaming agent) as a packaging material has been sold. For example, if a character doll popular with children is packaged with foamed bathing agent, the foamed bathing agent dissolves when placed in the bathtub, and character dolls appear inside (Non-Patent Documents 1 and 2). Children are surprised by the package that dissolves in the bathtub and look forward to what character dolls will appear.

  As the foam bathing agent used here, a mixture of a carbonate and an organic acid is generally used, for example, consisting of sodium bicarbonate and citric acid (Patent Document 1). By adding a small amount of water to powdered sodium bicarbonate and citric acid, stirring the mixture, pouring it into a mold and solidifying it, a foam bathing agent having a shape corresponding to the mold can be made (Non-patent Document 3). In addition, when the sodium bicarbonate and citric acid that have been stirred are put into the mold, the container is enclosed, so that the container can be packaged with a foam bath agent. When this package is put into the bathtub, sodium bicarbonate and citric acid react in the bathtub, and the foamed bathing agent partially vaporizes (carbon dioxide), the remainder dissolves in hot water, and the contents are on the water surface. It floats on.

  However, the character doll packaged in the above prior art must float on the surface of the water when the foaming bath agent dissolves, so it must be made of a material having a specific gravity smaller than that of water. It is released into the water and gets wet. Nonetheless, character dolls can be made of materials that do not easily change quality when exposed to baking soda and citric acid (carbonates and organic acids), and are usually allowed to get wet.

However, a container having a specific gravity greater than that of water, for example, jewelry such as jewelry and precious metals sinks to the bottom of a bathtub or the like and gets wet with water, and may be lost because it is small. In addition, gems and metals often change chemically when exposed to chemicals, and so cannot be packaged using conventional techniques. As described above, in the conventional technology, there are restrictions on the contents, such as matters relating to specific gravity, difficulty in chemical change due to chemicals, etc., and that it is permissible to get wet with water. Therefore, in the package of the prior art, it is impossible to meet the demands of people who wish to give gifts by packaging gifts selected from jewelry or precious metals with foaming agents.

The present application solves such problems in the prior art, and even if it is a container such as jewelry or precious metals, it can be prevented from being chemically changed by chemicals or getting wet with water while being wrapped with a foaming agent, It aims at providing the foaming agent package which can implement | achieve a surprise present.

  In order to solve the above-described problems, a foaming agent package according to the present invention has a packaging material that foams and dissolves when poured into water, and an inner package that is packaged inside the packaging material and encloses the contents. The specific gravity of the inner package in a state where the contents are enclosed is smaller than the specific gravity of water. Therefore, when the foaming agent package is put into water and the packaging material is dissolved, the inner package floats on the water surface. The Archimedes principle (the principle that an object in the liquid receives buoyancy equivalent to the weight of the liquid equal to its volume) receives buoyancy equal to the volume of the inner package, while the specific gravity of the inner package is lighter than the specific gravity of water This is because the gravity acting on the inner package is smaller than the buoyancy.

Of course, the contents do not come into contact with water until the inner package is opened. The inventor does not intend to limit the temperature of water, and the water in this specification includes hot water. Therefore, it is possible to produce a surprise effect that the packaging material is opened and the (unintentional) contents rise when the bath is used, for example.

  Here, the foaming agent package according to the present invention may have a plurality of inner packages. Further, in the inner package having the lid portion and the accommodating portion, it becomes easy to enclose the contained item in the inner package and to open the inner package.

  By the way, when the inner package is wet, it may be difficult to open. If the lid portion and the accommodating portion of the inner package have a cylindrical shape, these cylindrical regions, that is, the lid portion and the accommodating portion can be easily grasped with the fingertips, and the inner package can be easily opened.

Alternatively, if either one or both of the lid part and the housing part are formed of a flexible member, the inner space of the inner package can be obtained by pressing either one or both of the lid part and the housing part with a fingertip. The inner package can be easily opened by increasing the pressure. Further, by providing a cushioning material between the inner package and the accommodation, it is possible to prevent the accommodation enclosed in the inner package from being damaged.

  According to the foaming agent package of the present invention having the above-described configuration, even if the container has a specific gravity greater than that of water, the container can be easily picked up by floating on the water surface of the bathtub. Oxidation and the like caused by contact with the agent can be prevented, and the contents can be prevented from getting wet.

In addition, since the foaming agent package of the present invention wraps the inner package with an agitated foaming agent, the foaming agent is a relatively simple inner surface shape even in the case of a container having a complicated surface shape. Since only the package is in contact, it is possible to prevent a gap from being formed between the foaming agent and the container.
Therefore, according to the foaming agent package of the present invention, for example, gifts of various varieties such as jewels and rings are presented to the customer, and the gifts designated by the customer (gift giver) are packaged and presented to the gift recipient. We can provide high-quality foaming agent packages in businesses that deliver products.

It is a figure which shows one example of schematic structure of the inner package which the foaming agent package shown in FIG. 1 has. It is a figure which shows one example of the state which enclosed the accommodation thing in the inner package shown in FIG. It is a figure which shows schematic structure of the package shaping | molding die for shape | molding a foaming agent package. It is a figure which shows the modification of the inner package shown in FIG. It is a figure which shows the other modification of the inner package shown in FIG. It is a figure which shows an example of schematic structure of the inner package used in other Example (Example 2) of the foaming agent package concerning this invention by which the cover part and the accommodating part are connected with the hinge.

  Hereinafter, a foaming agent package according to the present invention will be described with reference to the drawings.

(Foaming agent package and inner package)
FIG. 1 is a diagram showing a schematic configuration of an embodiment of a foaming agent package according to the present invention. A foaming agent package 10 shown in FIG. 1 is obtained by wrapping an inner package 20A with a foam bathing agent 11 formed in a substantially spherical shape.

FIG. 2 is a diagram showing a schematic configuration of the inner package 20A. The inner package 20A is formed in a cylindrical shape in almost all regions except for both end portions thereof, and includes a lid portion 21 and a housing portion 22 each having a bottomed cylindrical shape. As shown in FIG. 3, the inner package 20 </ b> A is formed with an internal space 20 s and a bottom 21 t (hemispherical bottom) of the lid 21 in a state where the housing 22 is closed with the lid 21. The bottom portion 22b (hemispherical bottom portion) of the portion 22 forms both end portions of the inner package 20A.

As shown in FIG. 2, a cylindrical fitting portion 23 for fitting with the opening portion of the lid portion 21 extends in the opening portion of the accommodating portion 22. The outer peripheral surface 23a of the fitting portion 23 has an outer diameter that is substantially in close contact with the inner peripheral surface 21b of the peripheral wall 21a of the lid portion 21 to ensure the water tightness of the inner package 20A (in FIG. If the part 21 is moved in the direction of arrow A, the accommodating part 22 can be closed). In addition, in order to ensure sufficient water tightness in the fitting portion 23, the boundary portion between the lid portion 21 and the accommodating portion 22 and the vicinity thereof may be covered with a waterproof tape (film) or the like.

The inner package 20A is formed of, for example, a synthetic resin, and can reliably generate buoyancy according to its volume. If the inner package 20A is formed of a transparent or translucent synthetic resin, the inner package 20A can be accommodated. The object 30 can be visually observed from the outside (FIG. 3 shows an example when the accommodated object 30 is accommodated in the transparent inner package 20A). The inner package 20A is opened by easily grasping the respective cylindrical regions with the left hand / right hand and the right hand / left hand and twisting them as much as necessary because the lid portion 21 and the accommodating portion 22 both have a cylindrical shape. Can be opened without using tools such as scissors. Of course, even if the outer surface of the inner package 20A is wet with water, the lid portion 21 and the accommodating portion 22 can be easily grasped.

  The inner package 20A has a buoyancy suitable for the stored item 30 by appropriately selecting the axial length L of the receiving unit 22 according to the shape and weight of the stored item 30 (only by selecting the receiving unit 22). Can be realized. That is, if the weight of the volume of the inner package 20A is lighter than the weight of water having a capacity equal to the volume of the inner package 20A, the buoyancy is greater than the weight due to Archimedes' principle. The effect of rising is always obtained. Here, any of the axial lengths of the lid portion 21 and the accommodating portion 22 may be long. Further, the inner package 20A may have a flat outer shape in which the entire length in the axial direction is shorter than the outer diameter R of the housing portion 22 (lid portion 21).

Since the foaming agent package 10 using the inner package 20A can be used for packaging various kinds of stored items 30 only by selecting the storage unit 22, it is possible to reduce the packaging cost. Of course, you may respond | correspond to the shape and weight of the stored article 30 by selecting the outer diameter (outer diameter of the cover part 21 and the accommodating part 22) R of the inner package 20A.

(Containment and cushioning material)
Thus, the inner package 20A can enclose the contents 30 with water tightness. When enclosing the object 30 such as jewelry, it is desirable to enclose the object 30 by covering it with a cushioning material (not shown). If it does so, it can prevent that the accommodation 30 contacts with the inner surface of the inner package 20A, etc. during the transportation of the foaming agent package 10, etc.

  As the cushioning material, various materials such as a sheet-like resin and a material having an air cushion can be used. Further, even when the container 30 has a complicated outer shape, it is possible to use cotton or the like that can wrap the container 30 according to the outer shape and exhibits an excellent buffering action. Of course, the waterproofness may be enhanced by a water-repellent cushioning material such as oil paper. Such an inner package 20 </ b> A prevents the cushioning material from coming into direct contact with the foamed bath agent 11, so that the cushioning material can be prevented from being altered by the foamed bath agent 11. In addition, air cushions, cotton, and the like have a specific gravity that is lighter than that of water, which further contributes to the floating effect based on Archimedes' principle.

(Formation of foaming agent package)
The technique for making the foam bath agent 11 in a desired shape is known as a usage method of a so-called bath bomb maker, etc., but its outline will be described.

  The foam bathing agent 11 can be made into a shape corresponding to the mold by adding a small amount of water to powdered sodium bicarbonate and powdered citric acid, stirring the mixture, pouring it into a mold and solidifying it. FIG. 4 is a view for explaining a schematic configuration of a package molding die 40 that forms sodium bicarbonate and citric acid, which is stirred by adding water, into a spherical shape using a die.

  The package mold 40 includes a receiving mold 41 and a pressing mold 42, and the pressing mold 42 includes a pressing bar 43. Pour the stirred sodium bicarbonate and citric acid into the receiving mold 41. At this time, the inner package 20A is positioned substantially at the center of the package mold 40, and then stirred sodium bicarbonate and citric acid are poured into it, the receiving mold 41 is closed with the holding mold 42, and the receiving mold 41 and the holding mold are pressed with the holding bar 43. Pressure is applied to the mold 42. Eventually, the stirred sodium bicarbonate and citric acid are solidified into a substantially spherical shape in a foamed state, and the foaming agent package 10 is formed. At this time, the inner package 20 </ b> A is positioned substantially at the center of the foaming agent package 10.

(Injection into baths and dissolution)
A person who has been given the foaming agent package 10 encloses the gift 30 as an inner package 20A confined in the foaming bath 11 so that the gift is merely a foaming agent. You don't know what you are aware of or what the truly intended gift is in a foam. This is because the giver may not even tell you that a gift is present in an attempt to surprise the other party. In any case, the person who is given the foaming agent package 10 is intrigued by putting it into the bathtub and seeing the foaming bathing agent 11 foam and dissolve. Further, when the foam bathing agent 11 is foamed and dissolved, the inner package 20A appears on the hot water surface.

  Then, the person who has been given the foaming agent package 10 opens the package in anticipation or surprised by the unexpected appearance of the inner package 20A. Then, since the contents 30 such as jewelry appear, I am delighted. If this is what you want (for example, an engagement ring, birthstone jewelry, jewelry, etc.), it will be a double surprise, and the joy will be even higher. Of course, the inner package 20A floating on the hot water surface can be easily opened by grasping the lid portion 21 and the accommodating portion 22 with the left and right hands. If the inner package 20A is made of a transparent or translucent material, it is possible to know from the appearance what the gift is.

In this way, the foaming agent package 10 is filled with unexpectedness as a packaging, as well as a sense of expectation and unexpectedness for gifts, since the giver can select various items 30 and present them to the other party. Yes, you can expect surprise and enjoyment for the giver and the recipient, and expect the effect of increasing the intimacy of both.

(Modified inner package)
The inner package 20A can be variously modified without changing the gist of the present invention.

For example, the length of the peripheral wall 21a of the lid portion 21 may be substantially the same as the length of the fitting portion 23 as in the inner package 20A 'shown in FIG. Even in this case, the peripheral wall 21a of the lid portion 21 has a cylindrical shape and is easily grasped by hand.

Further, as shown in FIG. 6, in the case of the inner package 20 </ b> A ″ whose outer shape is substantially spherical with the housing portion 22 closed with the lid portion 21, the region having a cylindrical shape is substantially the fitting portion 23. In addition, only the peripheral wall 21a of the lid part 21 is provided, and the length W of the peripheral wall 21a of the fitting part 23 and the lid part 21 is significantly shorter than the outer diameter R of the peripheral wall 21a. If either one or both of the flexible members 22 are flexible, the inner space 20s is contracted by pressing either one or both of the lid portion 21 and the accommodating portion 22 with a fingertip. Since the pressure can be increased, the lid portion 21 can be easily separated from the accommodating portion 22.

By the way, the foaming agent package 10 may be a package of a plurality of inner packages 20A to 20B. A plurality of gifts wrapped in one foaming agent package 10 can be used as gifts from parents to children, for example, and when an event organizer gives gifts to many children. Can also be used.

Next, a foaming agent package according to another example (Example 2) will be described. In addition, about the component which has the same function as Example 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

The foaming agent package 10 according to Example 2 is obtained by packaging the inner package 20 </ b> B with the foaming bath agent 11.

7 is a diagram showing a schematic configuration of the inner package 20B (FIG. 7A is a plan view thereof, and FIG. 7B is a side view thereof). The inner package 20B is formed in an octagonal cylindrical shape. The inner package 20B includes a lid portion 21 and a housing portion 22 each having a bottomed cylindrical shape, and an internal space 20s is formed in a state where the housing portion 22 is closed by the lid portion 21. . The hinge part 24 is provided on one side of a rectangular cylindrical shape at the open end of the lid part 21 and the accommodating part 22 and connects the lid part 21 and the accommodating part 22 so that they can be opened and closed. A rectangular cylindrical fitting portion 23 extends from the opening of the accommodating portion 22. The inner package 20B can enclose the accommodation 30 in the same manner as the inner package 20A.

  In addition, this invention is not limited to the Example mentioned above, In the range which does not deviate from the meaning, it can change suitably and can implement.

In the present invention, for example, gifts of various varieties such as jewels, rings, necklaces, and earrings are presented to a customer, and gifts designated by the customer (gift giver) are packaged and delivered to a gift recipient. Can be used in business.
