The embodiment of the utility model provides a packing jar. The following are detailed below.

Referring to fig. 1, the package can 100 includes a can body 110 and a top cover 120, wherein a receiving cavity 112 for receiving a predetermined type of product 200 is formed in the can body 110, and the top cover 120 is covered on the can body 110 and closes the receiving cavity 112 to prevent the product 200 from being removed from the receiving cavity 112. Wherein, a first clapboard 1123 is arranged in the containing cavity 112 of the tank body 110, the first clapboard 1123 divides the containing cavity 112 into an upper cavity 1121 and a lower cavity 1122, a through hole 1123a communicating the upper cavity 1121 with the lower cavity 1122 is further opened on the first clapboard 1123, the upper cavity 1121 is used for containing the article 200, the article 200 is a dangerous article such as strong acid, strong base, toxic solution or toxic particles packaged by the containing tank, and when the containing tank is damaged, and the article 200 in the containing tank leaks, the leaked article 200 can flow into the lower cavity 1122 through the through hole 1123 a.

Specifically, the shape of the first partition 1123 is substantially the same as the cross-sectional shape of the accommodating chamber 112, and the peripheral edge of the first partition 1123 is connected to the inner side wall of the accommodating chamber 112 to divide the accommodating chamber 112 into an upper cavity 1121 and a lower cavity 1122 which are sequentially distributed in the up-down direction.

In some embodiments, as shown in fig. 1, a color-changing agent 114 is disposed in the lower cavity 1122 of the can 110, the color-changing agent 114 changes color when contacting a predetermined type of article 200, and at least a portion of the inner wall of the lower cavity 1122 is transparent. It is understood that when the article 200 in the upper cavity 1121 leaks, it flows into the lower cavity 1122 through the through hole 1123a and contacts the color-changing agent 114 in the lower cavity 1122, so that the color of the color-changing agent 114 is changed, otherwise, the color of the color-changing agent 114 is not changed. At least part of the inner wall of the lower cavity 1122 is transparent, so that whether the color of the color-changing agent 114 is changed or not can be checked through the inner wall of the lower cavity 1122, that is, whether the leakage of the articles 200 in the packaging can 100 occurs or not can be timely detected, and the safety performance of the packaging can 100 is improved.

Wherein the color-changing agent 114 may be a liquid or a solid, the specific type of which may depend on the type of article 200. For example: when the preset type of the object 200 in the package can 100 is strong acid or strong base, the color-changing agent 114 may be an acid-base indicator such as litmus, phenolphthalein, etc., and when the leaked strong acid or strong base flows into the lower cavity 1122 through the through hole 1123a, it reacts with the acid-base indicator to change the color of the acid-base indicator; when the predetermined type of the object 200 in the package can 100 is a mercuric nitrate solution, the color-changing agent 114 may be copper, and when the leaked mercuric nitrate solution flows into the lower cavity 1122 through the through-hole 1123a, it reacts with the copper to form a silver-white substance on the surface of the copper.

In some embodiments, as shown in fig. 1, an alarm device 115 is further disposed within lower cavity 1122, and alarm device 115 is configured to detect a predetermined type of article 200 in lower cavity 1122 and output an alarm signal. By arranging the alarm device 115 in the packaging can 100, the leakage condition of the articles 200 in the packaging can 100 can be further reminded, and the problem that the transport personnel or the receiver of the packaging can 100 forget to observe the color of the color-changing agent 114 and cannot timely perceive the leakage of the articles 200 in the packaging can 100 is avoided.

Specifically, the alarm device 115 includes a first detection terminal 1151, a power supply 1152, an alarm 1153 and a second detection terminal 1154 which are connected in series in sequence through a connection lead, and when a leakage occurs in a preset type of article 200 in the upper cavity 1121, the second detection terminal 1154 is conducted with the first detection terminal 1151 through the preset type of article 200 in the lower cavity 1122, so that the power supply 1152 supplies power to the alarm 1153, and the alarm 1153 outputs an alarm signal.

Specifically, the color-changing agent 114 is provided in a granular form, and the first detection terminal 1151 and the second detection terminal 1154 of the alarm device 115 are inserted into the color-changing agent 114, so that when the article 200 in the upper cavity 1121 leaks and flows into the lower cavity 1122, and extends from the first detection terminal 1151 to the second detection terminal 1154, the first detection terminal 1151 and the second detection terminal 1154 can be conducted, and the alarm 1153 outputs an alarm signal.

The color-changing agent 114 is made of an insulating material, or the first detection terminal 1151 and the second detection terminal 1154 are both separated from the color-changing agent 114 by a mesh-shaped separator, so as to prevent the color-changing agent 114 from making the first detection terminal 1151 and the second detection terminal 1154 conductive.

In some embodiments, as shown in fig. 1, a second partition 1124 is disposed in the lower cavity 1122, the second partition 1124 divides the lower cavity 1122 into a first sub-cavity 1122a and a second sub-cavity 1122b, the first sub-cavity 1122a is communicated with the upper cavity 1121 through a through hole 1123a, the color-changing agent 114 is disposed in the first sub-cavity 1122a, at least a portion of an inner wall corresponding to the first sub-cavity 1122a is transparent, and when the product 200 in the upper cavity 1121 leaks, the leaked product 200 flows into the first sub-cavity 1122a through the through hole 1123a, and then a transportation person or a receiver of the package can 100 can observe a color change of the color-changing agent 114 through the inner wall of the first sub-cavity 1122 a.

Thus, the power supply 1152 and alarm 1153 of the alarm device can be isolated from the color-changing agent 114 and the item 200 leaking into the first sub-cavity 1122a, thereby preventing the power supply 1152 and alarm 1153 of the alarm device from being damaged by the color-changing agent 114 or the item 200.

In some embodiments, the shape of the second partition 1124 is substantially the same as the cross-sectional shape of the lower cavity 1122, and the peripheral edge of the second partition 1124 is connected to the inner sidewall of the lower cavity 1122 to divide the lower cavity 1122 into a first sub-cavity 1122a and a second sub-cavity 1122b which are sequentially distributed in the up-down direction. Two penetrating detection holes 1124a are formed in the second partition 1124, and the first detection terminal 1151 and the second detection terminal 1154 of the alarm device 115 respectively penetrate through the two detection holes 1124a and extend into the first sub-cavity 1122a, so as to detect the article 200 leaked from the first sub-cavity 1122 a.

In other embodiments, the second barrier is perpendicular to the first barrier 1123, a top edge of the second barrier is connected to a lower surface of the first barrier 1123, both side edges of the second barrier are connected to an inner wall of the lower cavity 1122, and a bottom edge of the second barrier is connected to a bottom surface of the lower cavity 1122 to divide the lower cavity 1122 into a first sub-cavity and a second sub-cavity distributed in the left-right direction.

In some implementations, as shown in FIG. 1, alarm 1153 comprises a light alarm that outputs a light signal to indicate when second detection terminal 1154 is in communication with first detection terminal 1151 by an item 200 leaking from upper cavity 1121 into lower cavity 1122. The light alarm is a light emitting diode, a bulb, etc., and is not limited herein.

At least a part of the inner wall of the second sub-cavity 1122b is transparent, so that the transportation staff or the receiver of the packaging can 100 can observe the light signal output by the light alarm.

In other embodiments, as shown in fig. 3, the structure of the can body 110a and the top cover 120a of the package can 100a are substantially the same as the structure of the can body 110 and the top cover 120, except that the alarm 1153a of the alarm device 115a includes a voice alarm, and when the second detection terminal 1154a of the alarm device 115a is conducted with the first detection terminal 1151a through the article 200 leaked from the upper cavity 1121 into the lower cavity 1122, the power supply 1152a of the alarm device 115a supplies power to the voice alarm, so that the voice alarm outputs a voice signal for prompting. The voice alarm is a speaker, a buzzer, etc., and is not limited herein.
