[0002] Metal caps are a common packaging design, widely used in the packaging of various foods and beverages. The original intention of the design of metal caps is to facilitate consumers to open the package and improve the convenience of use. However, while providing convenience, metal caps also bring some problems, such as the detection and maintenance of sealing performance. If the sealing performance of the metal cap is not good, it may affect the quality of food or beverages, and may even cause the food or beverages to expire and deteriorate. At present, the sealed cans on the market will be equipped with an outer end cap on the outside of the metal cap to further protect the sealed can. However, the sealing performance of the outer end cap is limited. When the metal cap fails, the product in the sealed can is still easy to contact with the air, affecting the quality of the product. Summary of the invention

[0003] In view of the above-mentioned deficiencies, the technical problem to be solved by the utility model is to provide a reminder device for failure of sealing performance of a sealed can, which is used to monitor the status of the metal cover of the sealed can, thereby preventing food or beverages from being contaminated or deteriorating without being noticed.

DETAILED DESCRIPTION

[0021] The specific implementation scheme of the present utility model is as follows.

[0022] Embodiment 1

[0023] A reminder device for failure of sealing performance of a sealed can, the sealed can 1 comprising a can body 1-1, a metal cover 1-2 detachably fixed on the can body 1-1 and an outer end cover 1-3 covered on the outside of the metal cover 1-2, the reminder device being located between the metal cover 1-2 and the outer end cover 1-3, under normal conditions, when the metal cover 1-2 is sealed on the sealed can 1, the inside of the sealed can 1 is in a negative pressure state, and the metal cover 1-2 is in a properly sunken state, when the sealed can 1 is in a sealed state, the distance between the metal cover 1-2 and the outer end cover 1-3 is in a constant state, at which time the reminder device is not triggered; when the sealed can 1 leaks, the air pressure inside the sealed can 1 returns to atmospheric pressure, so that the distance between the metal cover 1-2 and the outer end cover 1-3 is reduced, at which time the pressure on the reminder device increases, the reminder device is triggered, and the user is reminded that the sealed can fails.

[0024] The reminder device includes a pressure sensing component 3 and a timer 2. The pressure sensing component 3 is arranged on the metal cover 1-2 and abuts against the bottom of the outer end cover 1-3, and is used to detect the change in the distance between the metal cover 1-2 and the outer end cover 1-3. When the distance between the metal cover 1-2 and the outer end cover 1-3 changes, the pressure sensing component 3 is triggered, and the timer 2 is connected to the pressure sensing component 3. When the pressure sensing component 3 is triggered, the timer 2 counts and records the triggering time of the pressure sensing component 3, thereby effectively recording the opening time of the food or beverage so that consumers can promptly understand the freshness of the food or beverage.

[0025] The pressure sensing assembly 3 includes a pressure sensor 3-1 and a pressing piece 3-2. The pressure sensor 3-1 is fixed on the metal cover 1-2. The pressing piece 3-2 is arranged between the pressure sensor 3-1 and the outer end cover 1-3. The pressing piece 3-2 is an elastic piece. The pressure sensor 3-1 and the pressing piece 3-2 are respectively connected to the processor. The processor is used to receive signals from the pressure sensor 3-1 and the pressing piece 3-2. When the distance between the metal cover 1-2 and the outer end cover 1-3 changes, the force exerted on the pressure sensor 3-1 by the pressing piece 3-2 changes. When the force exerted on the pressure sensor 3-1 exceeds a preset value, the processor determines that the sealing performance of the sealed can 1 fails. At the same time, the timer 2 starts to count the failure time.

[0026] A connection layer 3-3 is provided on the surface of the pressing member 3-2. The connection layer 3-3 has a certain viscosity. The pressing member 3-2 is connected to the surface of the pressure sensor 3-1 through the connection layer 3-3.

[0027] Embodiment 2

[0028] The deformation direction of the pressing member 3-2 in the first embodiment is unstable. When the deformation is too large, the pressing member 3-2 may fail. This embodiment improves the structure of the pressing member 3-2 on the basis of the first embodiment.

[0029] In this embodiment, the pressing piece 3-2 is made of rigid material, and the deformation of the pressing piece 3-2 is small. A connecting seat 3-4 is installed on the metal cover 1-2, and the pressure sensor 3-1 and the timer 2 are respectively installed on the connecting seat 3-4. The pressing piece 3-2 can be slidably installed on the connecting seat 3-4, so that the pressing piece 3-2 abuts against the pressure sensor 3-1 through the connecting seat 3-4.

[0030] A supporting layer 3-6 is provided in the connecting seat 3-4, and the interior of the connecting seat 3-4 is divided into a first installation cavity 3-7 for installing the pressure sensor 3-1 and a second installation cavity 3-8 for installing the pressing member 3-2 by the supporting layer 3-6. The spring 3-5 is respectively connected to the pressing member 3-2 and the supporting layer 3-6.

[0031] When the sealed can 1 is in a sealed state, the distance between the metal cover 1-2 and the outer end cover 1-3 is large, and the spring 3-5 lifts the pressing piece 3-2, so that the pressing piece 3-2 is separated from the pressure sensor 3-1. At this time, the pressure sensor 3-1 does not generate an electrical signal. When the seal of the sealed can 1 fails, the distance between the metal cover 1-2 and the outer end cover 1-3 decreases, and the spring 3-5 is compressed, so that the pressing piece 3-2 abuts against the pressure sensor 3-1. At this time, the pressure sensor 3-1 generates an electrical signal, and the processor determines that the sealing performance of the sealed can 1 has failed. At the same time, the timer 2 starts to count the failure time.

[0032] Connecting through holes 3-9 are provided at the top and bottom of the second mounting cavity 3-8, and both ends of the pressing piece 3-2 extend out of the second mounting cavity 3-8 through the connecting through holes 3-9 respectively, that is, when the sealing can 1 is in a sealed state, the lower end surface of the pressing piece 3-2 abuts against the pressure sensor 3-1 through the connecting through holes 3-9, and when the sealing can 1 is in a sealing failure state, the pressing piece 3-2 is lifted up so that the top of the pressing piece 3-2 extends out of the connecting through holes 3-9.

[0033] A limiting ring 3-10 is provided on the pressing piece 3-2, and the spring 3-5 abuts against the limiting ring 3-10, so as to facilitate the connection between the spring 3-5 and the pressure piece 3-2.

[0034] A display label 4 is arranged on the outside of the tank body 1 - 1 . The display label 4 is a display with a display function for displaying whether the sealed tank 1 is expired and the expiration time. As a preferred solution, a processor is arranged in the display label 4 for displaying the processed information on the display label 4 .

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0036] Although this article uses more terms corresponding to the figure marks in the figures, it does not exclude the possibility of using other terms; these terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
