Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a new message board. Specifically, the product's expiration date is displayed using a message, and the purpose is to easily and clearly show that the expiration date has come.

(Summary of the invention) The message board of this invention allows you to understand at a glance that a product has reached its expiry date. The expiration date of the product can be easily determined by the fact that the support part supporting the product decreases its supporting force within a certain period of time, the moving object moves, and a message appears.

(Prior Art) This type of message board includes those that display electrically using liquid crystals and the like, and those that display by changing the color of a chemical substance.

(Problem that the invention aims to solve) Many products have a fixed expiration date after opening. Some fresh food items have a shelf life of only two or three days after purchase, but the expiration date of these types of food items can be controlled by the purchaser's care. It is almost impossible to control the usage period of products that last for a week or month, or for products that are used for up to a year, such as deodorants. In addition, although the date of manufacture is generally stamped on the packaging material of the product, there is a problem in that it becomes difficult to tell once the packaging material is removed.

Therefore, there is a method that uses a liquid crystal or the like to electrically display the storage/use period, but this is expensive, and the message board itself is large and difficult to handle. In addition, there is a change in the color of chemical substances, but chromaticity is subjective and cannot necessarily be said to be an appropriate display.
Furthermore, there was a problem in that there was no standardization regarding which color the deadline was for, making it difficult for users to make decisions.

(Means for solving the problem) In order to solve the above-mentioned problems, the message board of the present invention includes a lid having a display window in a part thereof;
A movable body movable downward is provided in the upper part of the space defined by the frame body, the movable body is supported by a support part, and after a certain period of time, the support part supports the movable body. The object disappears, the moving object falls downward, and a message appears from the display window.

Therefore, according to the present invention, after a certain period of time has elapsed, the message informing the expiration date of the product, etc., the movable body falls from the upper part of the space to the lower part due to the decrease in the supporting force of the support part, and the transparent display window It has become possible to notify consumers of product expiration dates, etc.

Furthermore, it has a simple structure by providing a movable body and a support part within a space, and is easy to handle.

(Example) The details of the message board of the present invention will be explained below based on the illustrated example.

FIG. 1 is a perspective view showing a first embodiment of the message board of the present invention.

The message board 1 constitutes a type of container structure formed by a flat lid 3 having a display window 2 in a portion thereof, and a substantially rectangular frame 4.
Inside the space 5 defined by the lid 3 and the frame 4
A moving body 7 is provided in the upper part 6 of the space 5, and a support portion 9 for supporting the moving body 7 is provided in an intermediate portion 8 of the space 5. A message 10 is provided on the surface of the moving body 7 by appropriate means such as printing.

The lid 3, except for the display window 2, is made of opaque synthetic resin or the like. Therefore, in the lid 2 of this embodiment, the position corresponding to the upper part 6 of the space 5 is an opaque part, and the display window 2 is located at the lower part 1 of the space 5.
1, a message 10 is formed at a position where it can be seen when the moving body 7 moves to the lower part 11 of the space 5. The inside of the support part 9 is filled with a liquid substance 12 such as water that evaporates within a certain period of time when it comes into contact with the outside air, or a solid substance 12 that sublimates such as camphor or iodine.

FIG. 2 is a partial sectional view showing a first embodiment of the support part of the message board of the present invention.

In this embodiment, the support part 9 includes a bag-shaped exterior material 13 made of rubber or a easily deformable, thin-walled synthetic resin, etc., and a bag-like exterior material 13 that is housed in a completely sealed state inside the exterior material 13. Liquid substances that evaporate easily 1
It consists of 2. Hole 1 is provided on the upper side of the exterior material 13.
4, the protective material 16 seals the hole 14 and completely seals the absorbent material 15 made of cloth, cotton, etc.
is closely attached to the side wall of the exterior material 13 with removable double-sided tape or the like. This protective material 16 may be integrally fixed to a product packaging material (not shown) or the like. One end of the absorbent material 15 is in contact with the substance 12,
The other end protrudes outside the exterior material 13, and both ends are communicated through the hole 14.

FIG. 3 shows the state of use of the support section shown in FIG. 2 over time.

As shown in Figure 3A, message board 1
Before use, the movable body 7 is supported by the support portion 9 at the upper part 6 of the space 5 defined by the lid 3 and the frame 4. The support portion 9 is engaged with the inner wall of the intermediate portion 8 with the substance 12 filled inside the sheathing material 13 . In this embodiment, a portion of the exterior material 13 is fixed to the left inner wall of the intermediate portion 8 (when viewed from the front). When using the product, the protective material 16 is removed from the packaging material 13 by removing the packaging material from the product.
more peeled off. Note that, depending on the product, the protective material 16 may be directly peeled off. Then, the exterior material 13
The substance 12 inside is brought into communication with the outside air through the absorbent material 15, and the substance 12 begins to evaporate.

FIG. 3B shows a state in which the material 12 has been significantly vaporized.

As the substance 12 evaporates, the exterior material 1
3 contracts, leaving a portion fixed to the inner wall of the intermediate portion 8, and at the same time, the movable body 7 begins to fall little by little to the lower part 11 due to its own weight.

Eventually, as shown in FIG. 3C, the exterior material 13 completely shrinks, and the movable body 7 is no longer supported by the support part 9, and its own weight causes the inner wall of the intermediate part 8 and the support part 9 to collapse. With the outer surface of the exterior material 13
It passes through the space and falls to the lower part 11 of the space 5. A message 10 provided on the surface of the moving body 7 by the moving body 7 that has fallen to the lower part 11 informs the consumer through the display window 2 that the product has reached its expiry date, shelf life, or replacement date. It's getting old. In the above embodiment, the substance 12 inside the exterior material 13 is a liquid such as water, but it may be a sublimation material. In the case of a sublimation material, the same effect can be obtained by eliminating the need for the absorbent material 15 and by forming the pores 14 into a plurality of pores. Further, the exterior material 13 is preferably made of a thin, soft material fixed to the inner wall circumferential surface of the intermediate portion 8 by appropriate means, and after the sublimation material passes through the holes 14, 14, . . . The support part 9 is destroyed by its own weight, and the movable body 7 falls to the lower part 11. The sublimation material is mainly composed of sublimable crystals such as camphor, iodine, etc., and is solid or in the form of a dough.

Further, the substance 12 inside the exterior material 13 may be a plate-shaped moisture absorbing material with strong hygroscopicity. In this case, by directly peeling off a predetermined portion of the exterior material 13, the moisture absorbing material starts absorbing moisture, and after absorbing a certain amount of moisture, it becomes soft and cannot support the movable body 7, and the movable body 7 moves into the space 5. It falls to the lower part 11. Therefore, the exterior material 13 does not need to be provided with the holes 14.

FIG. 4 shows a second embodiment of the message board of the present invention.

In this embodiment, the display window 2 of the lid 3 is formed to correspond to the upper part 6 of a space 5 defined by the lid 3 and the frame 4. A through hole 1 is provided in the upper part of the moving body 7.
7 is formed, and a support portion 9 formed in a substantially cylindrical shape passes through this through hole 17 . Support part 9
The exterior material 13 is filled with a paste-like sublimation agent as the substance 12. One end of the substance 12 is in contact with a plurality of holes 14, 14, . It's summery. Further, the message 10 is provided on the bottom surface of the frame body 4 at a position corresponding to the display window 2,
The moving body 7 is made of opaque synthetic resin or the like, and is configured so that the message board 1 cannot be seen through the display window 2 before the message board 1 is used.

The state of use of the second embodiment will be explained in detail with reference to FIG. 5.

Before use, the holes 14, 14, . ing. [Figure 5A] When the protective material 16 is peeled off, the substance 12, which is a sublimation agent, is removed.
comes into contact with the outside air through the holes 14, 14, . . . and begins to sublimate. As the coil spring 18 is sublimated, it gradually extends, and when it reaches its maximum extension, it no longer presses the substance 12. As the sublimation progresses further, a gap is created between the coil spring 18 and the substance 12 due to the weight of the moving body 7, and cracks occur in the exterior material 13. [FIG. 5B] Then, the sublimation of the substance 12 continues, and finally the support portion 9 no longer supports the moving body 7, and the moving body 7 falls to the lower part 11. [FIG. 5C] When the movable body 7 falls to the lower part 11, a message 10 provided on the bottom surface of the upper part of the frame body 4 appears, and the consumer can recognize the expiration date of the product through the display window 2.

As mentioned above, the specific embodiment of the message board of the present invention has been shown, but the lid, frame, movable body,
The shape, material, etc. of the support portion can be modified as appropriate within the scope of those skilled in the art, as long as the purpose and effects of the present invention are achieved.

(Effects of the invention) As is clear from the above description, the message board of the invention supports the mobile object in advance by the support part in the upper part of the space defined by the lid and the frame, and for a certain period of time. After that, the support part no longer supports the movable body and the movable body falls to the lower part of the space, so that a message appears through the display window provided in the lid.

Therefore, according to the present invention, the message is not visible when the product is first used, but when the expiry date, shelf life, or replacement period of the product has come, the message is suddenly displayed through the display window.
Messages indicating expiration dates, etc. are now visible. Due to the presence of the message, consumers can easily and clearly understand the expiry date of the product.

In addition, the period for which the supporting force can be maintained depends on the size, amount, and material of the substance filled in the exterior material of the supporting section, as well as the size and area of holes and other appropriate means that come into contact with the outside air. can be selected arbitrarily, so the message board can be tailored to the type of product and mobile phone.

Furthermore, a message board can be created in the space with a simple structure of a moving body and a supporting part, making it extremely excellent in industry.
