Container structure with opening identification functions

Abstract

A container structure with opening identification functions has a container body, limit ring flange, cover body, engaging flange and a concealed prebreaking portion. The prebreaking portion must be set onto the container body but also located at a preset position inside the limit ring flange. When the cover body is covered onto the container body, the outer edge of the cover body is extended to conceal the prebreaking portion. Because the prebreaking portion is concealed by the cover body, when the consumers intend to take or carry the container body, or open or close the cover body, it is possible to avoid discomfort or accidental injury arising from contact with the broken position of the prebreaking portion. Further, ill-disposed individuals cannot easily open the cover body and insert foreign or harmful substances, thus ensuring the quality and safety of products in the container body.

1 . A container structure with opening identification functions comprising:
 a container body, having a preset cup or box pattern, the container body having a circumference wall, a bottom wall, an opening end and a holding space;   a limit ring flange, expanded outwards to be formed onto the opening end of the container body; and a recessed annular space is formed at an inner side of the limit ring flange;   a cover body, covered onto the opening end of the container body in an openable or closable state; when the cover body is covered onto the container body, the outer edge of the cover body is located into the recessed annular space of the limit ring flange;   an engaging flange, formed correspondingly to the opening end of the container body and the cover body in a mating position, such that the cover body could be locked securely;   a concealed prebreaking portion, which must be set onto the container body but also located at preset position inside the limit ring flange; when the cover body is covered onto the container body, the outer edge of the cover body is extended to conceal the prebreaking portion; when the limit ring flange is separated from the container body via the prebreaking portion, it allows to remove the cover body and identify if the cover body has been opened;   with this configuration wherein the prebreaking portion is concealed by the cover body, when the consumers are intended for removing the cover body, taking or carrying the container body, or opening/closing the cover body, it is possible to avoid any discomfort or even accidental injury arising from direct manual touch with the broken position of the prebreaking portion; on the other hand, those ill-disposed individuals could not easily pull open the cover body and put foreign or harmful substances into the container body, thus ensuring the quality and safety of products in the container body.   
     
     
         2 . The structure defined in  claim 1 , wherein said engaging flange comprises an annular flange formed inside the opening end of the container body and a ring concave edge located correspondingly to the cover body and the annular flange, such that the cover body is covered onto the opening end in a mating position. 
     
     
         3 . The structure defined in  claim 2 , wherein said prebreaking portion is formed circumferentially between the annular flange and limit ring flange of the container body. 
     
     
         4 . The structure defined in  claim 3 , wherein said prebreaking portion is designed into either of pre-breaking line, notch or rib. 
     
     
         5 . The structure defined in  claim 1 , wherein a connecting portion is set correspondingly to the container body and the cover body; said connecting portion is used to connect the container body and cover body, enabling the cover body to be covered rotarily onto the opening end and connected with the container body by taking the connecting portion as a rotary pivot, or, the cover body is directly covered onto the opening end and separated from the container body.
