Container for pet bottle

Abstract

The present invention relates to a product for daily life, and more particularly, to a container for covering a PET bottle that is capable of providing thermal insulation effects for the beverage contained in the PET bottle. The container for covering a PET bottle includes: a cap adapted to cover the upper portion of the PET bottle; and a body adapted to be coupled with the cap and to cover the lower portion of the PET bottle. As the container for covering a PET bottle forms a double bottle structure together with the PET bottle therein, the container can prevent a neighboring object or a user's had from coming into contact with condensed water generated due to dew condensation or the outer surface of the PET bottle which is carried, thereby keeping the neighboring object or user's hand from getting wet or keeping dirt from becoming attached to the PET bottle. Also, as the container has thermal insulation effects, warm or cold beverages remain drinkable over an extended time period. In addition, the container can be generally used for most of plastic beverage bottles on the market.

1 . A container for covering a PET bottle, the container being adapted to be coupled to the PET bottle having a flange formed along a mouth, the container comprising:
 a cap adapted to cover the upper portion of the PET bottle and having a coupling portion formed on the top portion thereof, the coupling portion being formed of a given hole having a size capable of passing the mouth of the PET bottle therethrough and not passing the flange therethrough;   a body adapted to be coupled with the lower end periphery of the cap to cover the lower portion of the PET bottle; and   a contact plate adapted to be located the inside bottom of the body and having a flat or dish-shaped support plate and an elastic member provided on the underside of the support plate and having a predetermined elasticity,   wherein, when the container is coupled to the PET bottle, the container forms a predetermined space between the outer wall of the PET bottle and the inner wall thereof to provide a double bottle structure with the PET bottle.   
     
     
         2 . A container for covering a PET bottle, the container being adapted to be coupled to a mouth of the PET bottle, the PET bottle having a flange formed along the mouth, the container comprising:
 a cap adapted to cover the upper portion of the PET bottle and having a coupling portion formed on the top portion thereof in such a manner as to be brought into close contact with a shoulder of the PET bottle, the coupling portion being formed of a given hole having a size capable of passing the flange of the PET bottle therethrough;   a body adapted to be coupled with the lower end periphery of the cap to cover the lower portion of the PET bottle; and   a contact plate adapted to be located on the inside bottom of the body and having a flat or plate-shaped support plate and an elastic member provided on the underside of the support plate and having a predetermined elasticity,   wherein, when the container is coupled to the PET bottle, the container forms a predetermined space between the outer wall of the PET bottle and the inner wall thereof to provide a double bottle structure together with the PET bottle.   
     
     
         3 . The container according to  claim 1 , wherein the elastic member of the contact plate is formed of three or more metal plate springs having a predetermined width, each of the three or more metal plate springs being attached to the underside of the support plate at one end thereof and being disposed on the inner bottom of the body at the other end thereof. 
     
     
         4 . A container for covering a PET bottle, the container being adapted to be coupled to a mouth of the PET bottle, the PET bottle having a flange formed along the mouth, the container comprising:
 a cap adapted to cover the upper portion of the PET bottle and having a coupling portion formed on the top portion thereof in such a manner as to be brought into close contact with the underside of the flange of the PET bottle, the coupling portion being formed of a given hole having a size capable of passing the flange of the PET bottle therethrough and having a plurality of locking plates bent elastically and a plurality of stopping plates adapted to be brought into contact with the top surface of the flange; and   a body adapted to be coupled with the lower end periphery of the cap to cover the body of the PET bottle, while having an air layer having a given thickness formed between the outer wall of the body of the PET bottle and the outer wall thereof,   wherein the flange of the PET bottle is fixed to the coupling portion.   
     
     
         5 . The container according to  claim 4 , wherein the locking plates of the coupling portion of the cap are formed of a plurality of spiral panel-shaped locking plates made by cutting a panel having a given width on which a spiral is formed to a predetermined length in a spiral direction. 
     
     
         6 . The container according to  claim 2 , wherein the elastic member of the contact plate is formed of three or more metal plate springs having a predetermined width, each of the three or more metal plate springs being attached to the underside of the support plate at one end thereof and being disposed on the inner bottom of the body at the other end thereof.
