Description

[Detailed description of the invention] (Industrial application field) This invention is to be attached to products such as foods, deodorants, deodorants, and other chemicals, and to easily confirm the storage expiration date or expiration date in a timely manner. About the time indicator that can be done.

(Prior art) Conventionally, as a time indicator of this kind, an indicator portion capable of determining the passage of time with the eyes of a reduced type, a sublimation type, a variable color type, etc. of a gel agent is provided on the surface of the base material, and the back surface of the base material There has been known a time indicator attached to a release paper via an adhesive layer applied to a paper.

After peeling off the time indicator from the release paper and attaching it to food, deodorant, deodorant, other chemicals, etc. with the adhesive on the back, the change in the color of the indicator part confirms the storage expiration date or expiration date etc. Is what you do.

Since the color of the indicator of the time indicator starts to change when it comes into contact with air, in order to cut off the contact with the air, after attaching the time indicator to the product, the product immediately together with the product, such as a laminate film, aluminum foil, etc. Sealed in a container such as a non-breathable bag,
The product must be stored and opened in a form that can be opened at the time of use.Therefore, it is necessary to seal each product, and the time indicator attached to the product must be clearly displayed. Is complicated.

Therefore, as shown in FIG. 6, the time indicator b which is obtained by peeling the release paper on the product a is attached to the commodity a, and the indicator part d of the time indicator b is provided substantially at the center of the back surface of the seal part c as shown in FIG. A cover seal g on which an adhesive layer f (for convenience, indicated by dots in the drawing) for forming a non-adhesive portion e larger than the size of the above is placed, and the indicator portion d is covered with the non-adhesive portion e. The adhesive layer f is adhered to the product a so that the indicator portion d
And sealed from air, and cover seal e
A knob h integrally provided on the outer peripheral edge of the seal portion c is gripped and peeled off from the product a, and the change in color tone of the indicator portion d is used to confirm the storage expiration date or the expiration date of the product.

(Problem to be Solved by the Invention) However, in the above configuration, when the indicator portion d of the time indicator b is covered with the seal portion c of the cover seal g, the non-adhesive portion e on the back surface of the seal portion c and the indicator portion d are covered. The work must be complicated because they must be covered so that the positions match, and when the indicator portion d and the non-adhesive portion e do not match, the adhesive layer f of the seal portion c adheres to the time indicator b, and the cover seal In addition to the difficulty in peeling g, there is a problem that the indicator part d is damaged.

Further, since the indicator portion d is covered with the cover seal g, the cover seal cannot be covered unless the time indicator is attached to the product, and both cannot be combined in advance. In addition, there is a problem that each of them must be separately sealed and stored, and when the exterior of the product is made of paper, the adhesive layer of the cover seal adheres to the exterior and cannot be removed.

In addition, after the cover seal g is peeled off, the position of the time indicator b to be attached becomes difficult to understand, so the position of the time indicator b must be displayed before the cover seal g is peeled off, and the indicator portion d of the indicator part d with time. Since the color tone changes, there is a problem that the initial color tone cannot be known and the storage of the product or the expiration date cannot be reliably confirmed.

An object of the present invention is to provide a time indicator that solves the above problem.

(Means for Solving the Problems) The time indicator of the present invention is provided with an indicator section on the surface of a base material, and a time indicator attached to release paper via an adhesive layer applied to the back surface of the base material. , A cover member having an opening through which the indicator section is provided is adhered to the surface of the time indicator, and only the edge of the cover seal covering the opening is heat-sensitively adhered to the surface of the cover member to seal the indicator section. A part is formed.

(Operation) By peeling off the release paper, the time indicator can be attached to any position of the product. In this case, the cover seal seals the indicator portion of the time indicator, and blocks the indicator portion from contacting with air. By peeling off the cover seal, the indicator of the time indicator touches the air.

(Embodiment) The present invention will be described below with reference to the drawings.

1 to 5 show one embodiment of the present invention, in which 1 indicates a time indicator, 2 indicates a covering member, and 3 indicates a cover seal.

The time indicator 1 has an indicator part 5 whose initial color tone is, for example, red and the color tone changes with time, is provided on the surface of a circular base material 4, and an adhesive layer 6 is provided on the back surface of the base material 4.

This configuration is not particularly different from the conventional time indicator, but the covering member 2 and the cover seal 3 are configured as follows according to the features of the present invention.

The covering member 2 has a circular opening 8 which has the same circular shape as that of the time indicator 1 and has a substantially tonal center portion of a base material 7 made of red having the same color, and which allows the indicator portion 5 of the time indicator 1 to be seen through. The display unit 9a is provided on the surface of the base material 7 near the outer peripheral edge thereof, and the opening 8
Display portions 9b were provided in the vicinity, and an adhesive layer 10 to be adhered to the surface of the time indicator 1 was provided on the back surface of the base material 7.

In the illustrated example, the display section 9a is set to the character "replacement guide", and the display section 9b is set to the character "replace when the center red becomes light."

The cover seal 3 is made of a plastic circular cover portion 11 on which aluminum is deposited, and a knob 12 is provided integrally with the cover portion 11 on the outer peripheral edge of the cover portion 11.
The display unit 13 was provided on the front surface of the device, and the heat-sensitive adhesive layer 14 was provided on the back surface of the cover unit 11.

In the illustrated example, the display unit 13 has the character "Please peel off."

Then, after a plurality of time indicators 1 are adhered to the release paper 15 via the adhesive layer 6 applied to the back surface of the base material 4, the covering members 2 are respectively applied to the surface of each time indicator 1.
Was adhered with an adhesive layer 10 applied to the back surface. Further, the cover seal 3 is placed on the surface of each covering member 2, and the cover portion 11 of each cover seal 3 is subjected to, for example, heat sealing, and only the periphery thereof is heat-sensitively bonded to the covering member 2, and the indicator portion 5 is formed. The sealing portion 16 was formed in an annular shape.

In this manner, the covering member 2 is adhered to the surface of the time indicator 1 and the indicator portion 5 of the time indicator 1 is sealed with the cover portion 11 of the cover seal 3 so that contact with air can be cut off. The time indicator can be attached to an arbitrary place of the product according to the above.

Further, since the cover seal 3 is heat-sensitively bonded to the covering member 2, if the cover seal 3 falls off before the use of the time indicator, the cover seal 3 cannot be adhered to the surface of the covering member 2 again. It is possible to quickly determine whether the time indicator 1 is in use or not, and when the cover seal 3 has fallen off, it can be immediately replaced with a new time indicator.

The material of the indicator section 5 provided on the surface of the base material 2 of the time indicator 1 in the present invention is not particularly limited as long as the color tone can be clearly distinguished between the time before use and the time after use as time passes. For example, a variable color type comprising a redox indicator and an air oxide, a sublimation type by sublimation of a sublimation substance, Patent No. 1534347 (Japanese Patent Publication No. 64-29)
No. 06), a material obtained by coexisting a variable dye that changes color in response to a change in pH and an alkaline substance on a base material, and the like.

In the illustrated example, the shape of the time indicator 1, the covering member 2 and the cover seal 3 is circular. However, the present invention is not limited to this, and these shapes may be polygons such as squares, hexagons, and ellipses. What is necessary is just to set suitably according to the shape of goods, such as a shape. In addition, time indicator 1,
The size of the covering member 2, the cover seal 3, and the opening 8 may be appropriately set according to the product to which the covering member 2, the time indicator 1, and the covering member 2 generally have a diameter of 10 when the shape is circular as in the above embodiment. The cover seal 3 generally has a diameter of about 8 to 45 mm when the shape is circular as in the above-described embodiment, and the opening 8 generally has a diameter when the shape is circular as in the above-described embodiment. The diameter is about 3 to 30 mm.

In addition, the shape and number of the openings 8 for see-through of the indicator portion provided in the covering member 2 may be appropriately set in accordance with the shapes of the time indicator 1, the covering member 2 and the cover seal 3.

In the above embodiment, the color tone of the covering member 2 is the same as the color tone of the indicator portion 5 of the time indicator 1. However, another color tone may be used. In this case, the color tone of the covering member is the final color tone at which the indicator portion is completely discolored. Alternatively, the color tone of the covering member may be set to two colors, one of which may be the same color as the indicator portion, and the other may be the final color tone which is completely discolored. In this way, it can be confirmed at a glance that the expiration date or the storage expiration date of the product has expired when the color tone of the indicator portion matches the color tone of the covering member or when the color tone matches the other color tone of the covering member.

In the above-described embodiment, the display on the display portions 9a and 9b of the covering member 2 and the display on the display portion 13 of the cover seal 3 are respectively characters. However, the present invention is not limited to this. It may be a combination.

(Effect of the Invention) As described above, according to the present invention, the time indicator is concealed except for the indicator portion by the covering member having the opening to be seen through, and the indicator portion is sealed by the cover portion of the cover seal. Since the indicator part of the time indicator can be shielded from the air, it can be stored in combination without sealing as a set in advance, and the time indicator can be attached to an arbitrary place of the product at any time. , The position of the time indicator can be easily confirmed by the covering member, and the cover seal is heat-sensitively bonded to form the sealing part of the indicator part, so the use of the time indicator and the unused state can be accurately judged. Also, if you remove the cover seal at the beginning of using the product, the indicator The portion has the effect of being able to easily and easily check the shelf life or expiration date of the product in a timely manner since the portion changes color with time upon exposure to air.

In addition, by forming the color tone of the covering member in the same color as the indicator portion or in a different color, the degree of discoloration of the indicator portion can be easily checked, and the position of the indicator attached to the product can be checked more easily.

In addition, by providing a display portion on the surface of the covering member and the cover seal, it is possible to reliably and easily handle the time indicator on a product to which the time indicator is to be attached, without performing display printing.
