Abstract
Description
Technical Field
[0001] This specification relates to memorial products for memory storage.
Background Art
[0002] Conventionally, methods of imparting information by printing or sealing have been used for time capsules and memorial products. However, there has been a risk that information may be lost in the storage environment due to problems such as fading of printing over a long period of time and peeling of seals. In addition, Patent Document 1 discloses a memorial product for a person or a pet. The memorial product includes a background area and a two-dimensional code engraved on a part thereof, and is known to hold information related to a person or a pet.

[0004] However, even when a two-dimensional code is engraved, there is a problem that readability decreases in a long-term storage environment due to a shallow engraving depth or the influence of surface treatment.
Summary of the Invention
Problems to be Solved by the Invention
[0005] In order to solve the above problems, as an aspect of the memorial product, the present invention aims to provide a configuration that is excellent in abrasion resistance and weather resistance and can hold information over a long period of time by engraving a two-dimensional code on a metal time capsule outer shell.
Means for Solving the Problems
[0006] The memory storage time capsule according to the present invention, as one embodiment of a memorial product, comprises a metal outer shell, a two-dimensional code engraved on a part of the outer shell (which may be formed by, for example, laser processing), and a lid member that can open and close the outer shell (which may be fastened by means such as a screw-in type, bolt-fixed type, or clamp type). and Alternatively, the configuration may include an O-ring or equivalent packing positioned at the joint between the lid member and the outer shell.
[0007] The aforementioned two-dimensional code may ensure visibility through color differences resulting from irregularities or surface treatments formed on the metal surface. For example, by utilizing irregularities formed by laser processing and color differences caused by oxidation, problems such as fading and peeling seen in printing and painting can be eliminated.
[0008] According to this invention, since the two-dimensional code is formed directly on the metal surface, the information may be retained for a long period of time and stable reading may be possible.
[0009] Furthermore, by employing a removable lid component (e.g., screw-in type, bolt-fixed type, etc.) equipped with an O-ring or equivalent gasket, waterproof and airtight seals can be ensured, allowing for the safe long-term storage of items stored inside.
[0010] Furthermore, by reading a two-dimensional code using a camera on a smartphone or similar device, it may be possible to easily access information related to the stored item. This information may include URL links to websites, social media, or databases associated with a person or pet.
[0011] The time capsule of this invention may contain items to be stored inside. These items may include letters, photographs, or DNA cards containing DNA information of people or pets.
[0012] According to the above configuration, items related to the items to be stored can be safely stored for a long period of time.
[0013] Furthermore, even when the lid is closed, the two-dimensional code is exposed on the outer surface and can be easily read by a camera such as a smartphone. [Brief explanation of the drawing]
[0014] [Figure 1] This is an external perspective view of the time capsule of the present invention. [Figure 2] This is a cross-sectional view of the time capsule of the present invention. [Figure 3] This is an enlarged view of the two-dimensional code imprinting portion related to the present invention. [Figure 4] This figure shows an example of how this invention can be used. [Modes for carrying out the invention]
[0015] The memory storage time capsule 1 shown in Figure 1 may be a memorial product created in association with a person or pet or other memory subject. The memory storage time capsule 1 comprises a cylindrical metal outer shell 2 and a lid member 3 that can be screwed onto the outer shell 2.
[0016] An O-ring or equivalent gasket 5 may be placed at the joint of the lid member 3 to ensure waterproofing and airtightness. The internal storage space 9 may be capable of accommodating memory items such as letters, photographs, and DNA cards.
[0017] A two-dimensional code 7 may be directly engraved on the outer surface of the outer shell 2. The two-dimensional code 7 may hold information related to the stored object, such as a URL link to access a website, social networking service, or database associated with a person or pet.
[0018] Since the two-dimensional code 7 is formed directly on the metal surface, it does not fade or peel like printing or painting, and can be read reliably over a long period of time.
[0019] As the material of the outer shell 2, aluminum, brass, stainless steel or other metal materials, ceramic or resin or other materials can be preferably used.
[0020] Note that the information held by the two-dimensional code 7 is not limited to the URL link, and may be information related to other storage targets such as name, date of birth, resume, message, image data, DNA information, etc.
[0021] As described above, the embodiments of the present invention have been described, but these are merely examples, and the present invention is not limited thereto. Each technical element described in this specification or the drawings exhibits usefulness alone or in combination, and includes various modifications as long as it does not deviate from the scope described in the claims at the time of filing.
