Child-resistant cap having inner and outer caps and a seal removing unit

Abstract

A child-resistant cap, which includes an inner cap mounted at a vessel inlet of a vessel; an outer cap disposed at an outer circumferential surface of the inner cap so as to perform an idling with the inner cap; a rotation force transmitting portion formed between the inner cap and the outer cap for transmitting a rotation force of the outer cap to the inner cap; and a sealing member punching unit formed at the inner cap for forming a hole at the sealing member and thereby discharging contents stored in the vessel outwardly through the hole, is disclosed.

1 . A child-resistant cap, comprising:
 an inner cap mounted at a vessel inlet of a vessel;   an outer cap disposed at an outer circumferential surface of the inner cap so as to perform an idling with the inner cap;   a rotation force transmitting portion formed between the inner cap and the outer cap for transmitting a rotation force of the outer cap to the inner cap; and   a sealing member punching unit formed at the inner cap for forming a hole at the sealing member and thereby discharging contents stored in the vessel outwardly through the hole.   
     
     
         2 . The cap of  claim 1 , wherein the sealing member punching unit comprises:
 a pressing plate disposed in the inner cap so as to be movable in upper and lower directions and downwardly moved when pressed by a user;   a punch formed at a lower surface of the pressing plate for forming a hole at the sealing member when the pressing plate is pressed; and   a connection portion connected between an outer circumferential surface of the pressing plate and an inner circumferential surface of the inner cap for guiding the pressing plate to be moved in upper and lower directions and maintaining a moved position of the pressing plate by its elastic force.   
     
     
         3 . The cap of  claim 2 , wherein the pressing plate is formed as a disc shape having a diameter smaller than an inner diameter of the inner cap. 
     
     
         4 . The cap of  claim 2 , wherein the punch comprises:
 a supporting rod perpendicularly extending from a lower surface of the pressing plate; and   a punching portion having a conical shape and formed at an end of the supporting rod for penetrating a center of the sealing member and forming a circular hole.   
     
     
         5 . The cap of  claim 2 , wherein the punch comprises:
 a rod portion perpendicularly extending from a lower surface of the pressing plate and having a sectional surface of a cross shape, for forming a hole having a cross shape at the sealing member; and   a punching portion sharply formed at an end of the rod portion for penetrating the sealing member.   
     
     
         6 . The cap of  claim 2 , wherein the punch is constructed as a plurality of pins formed at a lower surface of the pressing plate for forming a plurality of minute holes at the sealing member. 
     
     
         7 . The cap of  claim 2 , wherein the connection portion is formed between an outer circumferential surface of the pressing plate and an inner circumferential surface of the inner cap as a thin film having a dome shape, and is elastically transformed when the pressing plate is pressed by a force more than a certain degree. 
     
     
         8 . The cap of  claim 2 , wherein a protection plate for protecting the sealing member removing unit formed at the inner cap is formed at an upper surface of the outer cap. 
     
     
         9 . The cap of  claim 8 , wherein the protection plate is formed at an upper inner circumferential surface of the outer cap with a certain gap as a disc shape, and a plurality of connection ribs cut when the protection plate is downwardly moved and maintaining a fixed state of the protection plate to the outer cap are formed between an outer circumferential surface of the protection plate and an upper inner circumferential surface of the outer cap.
