[Brief description of the drawings]

[0014] [Figure 1] 1 is a perspective view showing the appearance of an electronic device cover and a fragrance holding member according to a first embodiment. [Diagram 2] 3 is a cross-sectional view showing a state in which the electronic device cover of the first embodiment and a fragrance holding member are in contact with each other. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, with reference to the drawings, an embodiment of the present invention will be described using an electronic device cover used as a protective cover for a smartphone as an example. The present invention is not limited to the specific embodiments shown below, and the form can be modified and implemented.

[0016] 1, an electronic device cover 1 is attached to an electronic device 9 such as a smartphone and functions as a protective cover. A smartphone is a portable information terminal equipped with a mobile phone function and an Internet access function, and well-known examples include the iPhone (registered trademark) and Android (registered trademark) terminals.

[0017] The specific form in which the electronic device cover 1 is attached to the electronic device 9 is not particularly limited. The shape and design of the electronic device cover 1 can be freely set as long as the functions described below are not impaired. The electronic device cover 1 may be provided with holes, protrusions, recesses, engagement parts, hinges, etc., suitable for the operation and movement of the electronic device 9. When the electronic device 9 is a smartphone, the electronic device cover 1 is typically formed in a shallow box shape with an open top, and is attached to the electronic device by utilizing the side portion of the box. The electronic device cover 1 may have elasticity for convenience of attachment. The electronic device cover 1 may have other portions (for example, a member for protecting the screen), and may be attached to the electronic device by other attachment methods.

[0018] The electronic device cover 1 of this embodiment can be used in an aromatic state. When the electronic device cover 1 is aromatic, it can leave a pleasant fragrance inside a bag containing a smartphone, or emit a pleasant fragrance when the smartphone is operated, for example.

[0019] The electronic device cover 1 includes a plate-like portion 11 formed of silicone rubber or silicone resin. Typically, the plate-like portion 11 is flat, but the plate-like portion 11 may be curved. In FIG. 1, the plate-like portion 11 is shown surrounded by a dashed line. In this embodiment, the surface corresponding to the bottom surface of the box is the plate-like portion 11. The electronic device cover 1 may be entirely formed of silicone rubber or silicone resin, or the plate-like portion 11 may be formed of silicone rubber or silicone resin and the other portions may be formed of other resin materials. Although not required, in this embodiment, the electronic device cover 1 is entirely formed of silicone rubber or silicone resin.

[0020] The silicone rubber is not particularly limited, but examples thereof include silicone rubbers such as KE series from Shin-Etsu Chemical Co., Ltd. The silicone resin is not particularly limited, but examples thereof include KR series from Shin-Etsu Chemical Co., Ltd. The electronic device cover 1 and the fragrance holding member 2 described below may be formed by mixing silicone rubber and silicone resin. The silicone rubber may be blended with silicone resin. The silicone resin may be blended with silicone rubber. In other words, the term "silicone rubber or silicone resin" in this specification includes a mixture of silicone rubber and silicone resin.

[0021] The silicone rubber or silicone resin constituting the electronic device cover 1 is not particularly limited as long as it maintains the shape of the cover and exhibits the operating function and protective function of the electronic device, etc. The silicone rubber or silicone resin constituting the plate-like portion of the electronic device cover 1 may be crosslinked, partially crosslinked, or substantially uncrosslinked.

[0022] When electronic device 9 is used together with electronic device cover 1, the fragrance component contained in plate-like portion 11 made of silicone rubber or silicone resin is dispersed into the air, thereby giving off a fragrance.

[0023] Below, we will explain a method for manufacturing an aromatic electronic device cover 1 by retaining a fragrance component in a plate-shaped portion 11 formed of silicone rubber or silicone resin, a method for imparting fragrance to the electronic device cover 1, and a method for restoring the fragrance of the electronic device cover 1.

[0024] A fragrance-holding member 2 containing a fragrance component and made of silicone rubber or silicone resin is prepared.

[0025] Any fragrance component can be contained in the fragrance holding member 2 so as to obtain a desired fragrance. Although not essential, it is preferable to add a fragrance containing any of β-citronellol, 4-tert-butylcyclohexyl acetate, allyl heptanoate, CIS-3-hexenyl acetate, allyl hexanoate, and calone as the fragrance component.

[0026] These fragrance components may be preliminarily kneaded into the silicone rubber or silicone resin that constitutes the fragrance holding member 2. Alternatively, the fragrance components may be incorporated into the fragrance holding member 2 by applying the fragrance components to the fragrance holding member 2 formed of silicone rubber or silicone resin, or by immersing the fragrance holding member 2 in a liquid containing the fragrance components.

[0027] The silicone rubber or silicone resin constituting the fragrance retention member 2 is not particularly limited, and may be crosslinked, partially crosslinked, or substantially non-crosslinked. Preferably, the silicone rubber or silicone resin constituting the fragrance retention member 2 has enough adhesion or tackiness to allow the fragrance retention member 2 to adhere to the plate-like portion 11 of the electronic device cover 1. The silicone rubber or silicone resin constituting the fragrance retention member 2 may contain liquid components such as silicone oil, fillers, modifiers, etc.

[0028] Although not essential, it is preferable that the fragrance holding member 2 is made of uncrosslinked silicone rubber or silicone resin. Uncrosslinked silicone rubber or silicone resin is easily deformed, and therefore the adhesiveness of the resin is high, so that the fragrance holding member 2 can easily adhere to the plate-like portion 11 of the electronic device cover 1. It is particularly preferable that the uncrosslinked silicone rubber or silicone resin has plasticity.

[0029] Furthermore, although not essential, when the fragrance holding member 2 is made of uncrosslinked silicone rubber or silicone resin, the Williams plasticity of the uncrosslinked silicone rubber or silicone resin constituting the fragrance holding member 2 is preferably 60 to 500. It is particularly preferable that the Williams plasticity is 100 to 300. If the uncrosslinked silicone rubber or silicone resin has such a plasticity, the fragrance holding member 2 is easy to handle and can be particularly easily adhered to the plate-like portion 11 of the electronic device cover 1.

[0030] The Williams plasticity index is based on the international standard ISO7323 and is calculated by multiplying the thickness of a cylindrical specimen having a diameter of 16 mm and a height of 10 mm by 100, the thickness being measured a predetermined time after pressing (5 minutes in this specification) using a parallel plate plasticity tester at a predetermined temperature (room temperature of 23°C in this specification) to a final load of 49 N.

[0031] Although not essential, in this embodiment, the fragrance retention member 2 is plate-shaped. If it is plate-shaped, a small amount of fragrance retention member can bring the fragrance retention member 2 into contact with the plate-shaped portion 11 of the electronic device cover 1 over a wide area. The external shape of the plate-shaped fragrance retention member 2 is not particularly limited, and may be rectangular as in this embodiment, or may be other shapes such as circular or the shape of a character.

[0032] The fragrance-retaining member 2 can be manufactured, for example, by kneading additives such as fragrance components and silicone oil into a millable-type uncrosslinked silicone rubber to produce an uncrosslinked rubber material, and then molding the uncrosslinked rubber material into a sheet. These processes are known. If the fragrance-retaining member 2 is crosslinked, a crosslinking process may be added to the process of molding the fragrance-retaining member 2 or a process thereafter. The molding process of the fragrance-retaining member 2 may utilize roll molding, press molding, or injection molding.

[0033] The silicone rubber or silicone resin constituting the fragrance retention member 2 may be one that is capable of maintaining its solid shape. Examples of the means for maintaining its solid shape include crosslinking, partial crosslinking, gelation, and the like.

[0034] When the silicone rubber or silicone resin constituting the fragrance holding member 2 is capable of maintaining its shape as a solid, the silicone rubber or silicone resin preferably has a durometer A hardness of 10 to 50 degrees measured with a type A durometer conforming to JISK-6253, and preferably has an Asker C hardness of 20 to 70 degrees as specified in the Society of Rubber Industry Standards (SRIS 0101). When the hardness of the silicone rubber or silicone resin is within this range, the fragrance holding member 2 is particularly likely to adhere to the plate-like portion 11 of the electronic device cover 1.

[0035] The prepared fragrance holding member 2 is used to manufacture the fragrant electronic device cover 1 of the above embodiment. For example, a cover formed of silicone rubber or silicone resin by means of injection molding or the like can be used as the electronic device cover 1. A commercially available electronic device cover made of silicone rubber or silicone resin can also be used as the electronic device cover 1.

[0036] As shown in Fig. 2, the plate-like portion 11 of the prepared electronic device cover 1 is brought into contact with the fragrance holding member 2. At this time, the plate-like portion 11 of the prepared electronic device cover 1 may or may not contain a fragrance component. Even if the plate-like portion 11 of the prepared electronic device cover 1 does not contain a fragrance component, such as when using a commercially available electronic device cover on the market, an electronic device cover 1 having an aromatic property can be obtained by the method described below.

[0037] The plate-like portion 11 of the electronic device cover 1 and the fragrance holding member 2 are kept in contact for a predetermined time, and the fragrance component is transferred from the fragrance holding member 2 to the plate-like portion 11. The contact time is not particularly limited, and may be, for example, about overnight. The contact between the plate-like portion 11 of the electronic device cover 1 and the fragrance holding member 2 is preferably such that they are in close contact over the entire contact surfaces of the plate-like portion 11 and the fragrance holding member 2. By being in close contact, the transfer of the fragrance component is more efficient.

[0038] The fragrance component is transferred to the plate-like portion 11 of the electronic device cover 1, and the electronic device cover 1 becomes an fragrant electronic device cover. That is, through the contact step between the plate-like portion 11 and the fragrance holding member 2, the fragrant electronic device cover 1 is manufactured. By manufacturing the aromatic electronic device cover 1 in this manner, there is no need for a complex structure such as a lid or a portion for housing the aromatic chip as in the technique of Patent Document 2. In other words, it is possible to obtain an aromatic electronic device cover 1 with a simple structure.

[0039] According to the manufacturing method of the above embodiment, both the plate-like portion 11 of the electronic device cover 1 and the fragrance holding member 2 are made of the same type of resin material, namely silicone rubber or silicone resin. Since both are made of silicone rubber or silicone resin, the fragrance component is efficiently transferred to the plate-like portion 11 of the electronic device cover 1 in the above contact step. In manufacturing an electronic device cover 1 with an aromatic property, that is, in order to efficiently transfer the fragrance components from the fragrance holding member 2 to the plate-shaped portion 11, it is preferable that the plate-shaped portion 11 of the electronic device cover 1 and the fragrance holding member 2 are in close contact with each other, and if the fragrance holding member is made of uncrosslinked silicone rubber or silicone resin, or if the Williams plasticity of the uncrosslinked silicone rubber or silicone resin constituting the fragrance holding member is 60 to 500, the degree of contact is increased, promoting the transfer of the fragrance components, and an electronic device cover 1 with an aromatic property is efficiently manufactured.

[0040] Although not essential, the temperature of the fragrance retention member 2 or the plate-like portion 11 of the electronic device cover 1 may be made higher than room temperature to promote the transfer of the fragrance component. For example, by attaching the fragrance retention member 2 to a charger or the like, whose temperature is higher than room temperature, and bringing it into contact with the plate-like portion 11 of the electronic device cover 1, the transfer of the fragrance component is promoted, and the electronic device cover 1 having a fragrance can be manufactured more efficiently.

[0041] Furthermore, if the fragrance-holding member 2 has adhesiveness or tackiness, it becomes easier to maintain contact between the fragrance-holding member 2 and the plate-like portion 11 of the electronic device cover 1, and the transfer of the fragrance component becomes more reliable, so it is preferable that the fragrance-holding member 2 has adhesiveness or tackiness.

[0042] In addition, by contacting the fragrance holding member 2 with the plate-like portion 11 of the electronic device cover 1, the fragrance component can be transferred to the plate-like portion 11, thereby imparting a fragrance to the electronic device cover formed of silicone rubber or silicone resin. Furthermore, even if the fragrance becomes weak or is lost when using an electronic device cover made of fragrant silicone rubber or silicone resin, the fragrance component can be transferred to the plate-like portion 11 and replenished by contact between the fragrance holding member 2 and the plate-like portion 11 of the electronic device cover 1, thereby restoring the fragrance of the electronic device cover made of silicone rubber or silicone resin.

[0043] If the fragrance retaining member 2 is brought into contact with an electronic device cover that does not substantially contain a fragrance component, i.e., an electronic device cover that does not have a fragrance, and the fragrance component is transferred to the plate-shaped portion 11, for example, a commercially available electronic device cover that does not have a fragrance can be used to manufacture an electronic device cover having a fragrance, and an electronic device cover can be manufactured while utilizing an existing cover. In this way, an electronic device cover having a fragrance can be manufactured by the above manufacturing method from an existing electronic device cover that does not have a fragrance, at the user's choice, and the manufacturer of the electronic device cover does not need to separately manufacture and distribute those with and without a fragrance, which is efficient.

[0044] Furthermore, if the fragrance component can be transferred to the plate-like portion 11 of the electronic device cover 1 by contact between the fragrance retaining member 2 and the plate-like portion 11, the fragrant electronic device cover can be used repeatedly even if the scent becomes weak, making it economical.

[0045] The invention is not limited to the above-mentioned embodiment, and can be practiced with various modifications. Other embodiments of the invention will be described below, but in the following description, the differences from the above-mentioned embodiment will be mainly described, and detailed descriptions of similar parts will be omitted. In addition, these embodiments can be practiced by combining parts with each other or by replacing parts.

[0046] In the above embodiment, an example was given in which the plate-shaped fragrance holding member 2 is used so as to contact, preferably adhere to, the plate-shaped portion 11 of the electronic device cover 1, but the fragrance holding member 2 may have other shapes, such as a hemisphere, a pyramid, a prism, a cylinder, a rectangular parallelepiped, etc., as long as it can be in sufficient contact with the plate-shaped portion 11. Preferably, the shape of the fragrance holding member 2 has a flat portion.

[0047] Furthermore, when the flavor-retaining member is plastic, such as being uncrosslinked, the shape of the flavor-retaining member is not particularly limited as long as a sufficient contact surface is ensured when the flavor-retaining member comes into contact with the plate-like portion 11. If the flavor-retaining member is plate-shaped, this is preferable because it is easy to handle during use and storage of the flavor-retaining member.

[0048] Furthermore, if the fragrance-holding member 2 has adhesiveness or tackiness, the adhesiveness or tackiness may be utilized to maintain contact between the fragrance-holding member 2 and the plate-like portion 11 of the electronic device cover 1, or the adhesiveness or tackiness of the fragrance-holding member 2 may be utilized to integrate the fragrance-holding member 2 with a charging device, the top surface of a desk, etc.

[0049] It is possible to appropriately change the type and combination of fragrance components contained in the fragrance retention member 2. For example, multiple types of fragrance retention members 2 with desirable fragrance types and images, such as green, floral, citrus, musk, etc., may be prepared, and a fragrance retention member may be selected according to the fragrance to be imparted, to manufacture the electronic device cover 1 with the desired fragrance.

[0050] In addition, depending on the amount and type of fragrance component remaining in the plate-like portion 11 of the electronic device cover 1, it is possible to change the scent of the electronic device cover 1 or blend scents by preparing a fragrance retention member 2 containing a fragrance component different from the fragrance component originally contained in the electronic device cover 1 and contacting the fragrance retention member 2 with the plate-like portion 11 to transfer the fragrance component.

[0051] In addition, the step of contacting the above-mentioned fragrance holding member 2 with the plate-shaped portion 11 and transferring the fragrance component from the fragrance holding member 2 to the plate-shaped portion 11 may be performed by a business that manufactures and sells the electronic device covers, i.e., a manufacturer or distributor, or may be performed by a user of the electronic device covers and electronic devices, i.e., a user.

[0052] The type of electronic device to which the electronic device cover is attached is not particularly limited. In addition to the already exemplified electronic devices such as mobile phones, smartphones, tablet terminals, personal computers, notebook computers, monitors, etc., the above method can also be used to impart fragrance to covers used in electronic devices such as game devices and game console controllers. In particular, when the electronic device is a portable device such as a mobile phone, smartphone, or tablet, an electronic device cover that has a simple structure yet has a fragrant property is useful. [Industrial Applicability]

[0053] According to the above-described manufacturing method, it is possible to manufacture an aromatic electronic device cover that can be used for, for example, a smartphone, and the method has high industrial applicability. [Explanation of symbols]
