Vented sealable bag

Abstract

A vented sealable bag comprises a container, a two-part seal and a vent. The container has opposing sidewalls and a bottom defining a cavity. The sidewalls form a neck defining an opening opposite the bottom, The sidewalls have an inner surface facing the cavity and an outer surface external to the container and the sidewalls have a thickness. A two-part seal is formed on the inner surface of the sidewalls adjacent the neck. The two-part seal has a hook formed on one sidewall and a clasp formed on an opposite sidewall. The hook and clasp are arranged on the inner surface of the sidewalls to form an airtight seal isolating the cavity from an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container. A vent is integrally formed in one of the sidewalls. The vent is further comprised of a dimple having a thickness that is thinner than the thickness of the sidewalls. The dimple is concave when viewed from the cavity and has a slit formed at an apex that is closed except when the container is sealed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.

         4 . The vented sealable bag of  claim 1 , constructed of a flexible polymeric material. 
     
     
         5 . The vented sealable bag of  claim 1 , constructed of silicone. 
     
     
         6 . The vented sealable bag of  claim 1 , wherein the bottom forms a rectangular platform. 
     
     
         7 . The vented sealable bag of  claim 1 , wherein the bottom forms a platform sufficient to support the vented sealable bag. 
     
     
         8 . A vented sealable bag comprising:
 A container having two opposing sidewalls and a bottom that define a cavity, the sidewalls forming a neck defining an opening opposite the bottom, the sidewalls having an inner surface facing the cavity and an outer surface external to the container;   A two-part seal formed on the inner surface of the sidewalls below the neck, the two-part seal having a hook formed on one sidewall and a clasp formed on an opposite sidewall, the hook and clasp are arranged on the inner surface of the sidewalls to form a seal preventing contents of the container from communicating with an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container; and;   A vent integrally formed in one of the sidewalls, the vent is further comprised of a dimple, the dimple is concave when viewed from the cavity and has a cut opening that forms an airtight seal except when the two-part seal is closed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.   
     
     
         9 . The vented sealable bag of  claim 8 , wherein the vent has a dimple thickness equal to or greater than the thickness of the sidewalls. 
     
     
         10 . The vented sealable bag of  claim 8 , wherein the container, two-part seal and the vent are constructed of an impermeable flexible material. 
     
     
         11 . The vented sealable bag of  claim 8 , wherein the container, two-part seal and the vent are constructed of silicone. 
     
     
         12 . The vented sealable bag of  claim 8 , wherein the cut opening is a slit. 
     
     
         13 . The vented sealable bag of  claim 8 , wherein the cut opening is a duck bill valve. 
     
     
         14 . A vented sealable bag comprising:
 A container having two opposing sidewalls and a bottom, the sidewalls and bottom define a cavity, the bottom forms a platform, the sidewalls forming a neck defining an opening opposite the bottom, the sidewalls having an inner surface facing the cavity and an outer surface external to the container;   A two-part seal formed on the inner surface of the sidewalls below the neck, the two-part seal having a hook formed on one sidewall and a clasp formed on an opposite sidewall, the hook and clasp are arranged on the inner surface of the sidewalls to form a seal preventing contents of the container from communicating with an external environment when the hook is embedded in the clasp in a closed condition but otherwise maintain the opening in the container when the hook and clasp are in an open condition; and   A vent integrally formed in one of the sidewalls, the vent is further comprised of a dimple, the dimple is concave when viewed from the cavity and has an opening that forms an airtight seal except when an internal pressure in the cavity is greater than an external pressure on the outer surface of the sidewalls.   
     
     
         15 . The vented sealable bag of  claim 14 , wherein the container, two-part seal and the vent are constructed of a flexible material.
