Package filled with gel or paste content and gas

Abstract

This invention provides a package comprising a formed product, formed by heat welding a sheet-like planar polymeric film to form the film into a cylindrical form. The formed product is filled with a gel product and a viscous paste product as contents, which are very stable and are not separated from water, together with gas. In this package, upon opening, the gel product is easily discharged without adhering or sticking to a surface of contact with a polymeric film surface, and, further, the whole quantity of the paste product is discharged into the formed product without adhering and staying.

1 . A package comprising:
 a formed product formed into a form of a cylinder by heat welding a sheet-like planar polymeric film; and   a gel or paste content and gas encapsulated in the formed product, wherein:   the formed product includes a drum part and heat-sealed parts on at least one longitudinal end of the drum part and a longitudinal side portion of the drum part;   the drum part includes a gel or paste content-encapsulated part and a gas-encapsulated part, which are divided in the longitudinal direction thereof; and   an opening notch is provided on the heat-sealed part formed on the longitudinal side portion of the drum part, such that the notch is formed between the tip of content, which is opposite to the gas-encapsulated portion, on the side of the content-encapsulated portion and the tip of content on the side of the gas-encapsulated portion, and the notch has a shape of I or V type and placed perpendicular to the longitudinal direction of the drum part, while the notch is inclined at an inclination angle of 45 degrees to 80 degrees to be split toward the tip of the content opposite to the gas-encapsulated portion.   
   
   
       2 . A package according to  claim 1 , wherein a ratio of a long diameter to a short diameter of a cross-section of the drum part is 1:1 to 1:0.3. 
   
   
       3 . A package according to  claim 1 , wherein a volume ratio of the gel or paste contents to the gas is 9:1 to 1:9. 
   
   
       4 . A package according to  claim 1 , wherein the gas comprises air, nitrogen gas, argon gas, helium gas, or carbon dioxide. 
   
   
       5 . A package according to  claim 1 , wherein:
 the sheet-like planar film is a monolayer or a laminate of two or more layers glued together;   the sheet-like planar film is made of a transparent or opaque material; and   the sheet-like planar film has a thickness of 50 to 200 μm.   
   
   
       6 . A package according to  claim 1 , wherein the heat-sealed part of the longitudinal side portion of the drum part has a width of 5 to 15 mm, and the heat-sealed part of at least one longitudinal end of the drum part has a width of 5 to 40 mm. 
   
   
       7 . A package according to  claim 1 , wherein a lubricant is further applied to a contact portion between the sheet-like planar film and the gel or paste contents.
