Plastic mounting cup and valve for pressurized container

Abstract

The present disclosure relates to a valve for dispensing flowable product from a container under pressure, the valve comprising a stem, a seal coupled to the stem, and a mounting cup configured to mount the valve to the container, wherein each of the stem, seal, and mounting cup comprises a recyclable plastic, and wherein the valve is free from a gasket configured to surround an opening of the container to form a seal between the valve and the container. Also provided herein is a container for dispensing a flowable product under pressure comprising the valve as described above.

         57 . The valve set forth in  claim 51 , wherein the stem plastic material has a density less than about 1 g/cm 3 . 
     
     
         58 . The valve set forth in  claim 57 , wherein the stem consists essentially of the stem plastic material. 
     
     
         59 . The valve set forth in  claim 58 , wherein the stem plastic material is polypropylene (PP). 
     
     
         60 . The valve set forth in  claim 51 , wherein the stem plastic material has a density less than about 1 g/cm 3 , the stem consisting essentially of the stem plastic material,
 wherein the seal consists essentially of the seal plastic material,   wherein the mounting cup consists essentially of polyethylene terephthalate (PET).   
     
     
         61 . The valve set forth in  claim 60 , wherein the seal plastic material is a thermoplastic elastomer. 
     
     
         62 . The valve set forth in  claim 60 , in combination with the container body, wherein the container body comprises polyethylene terephthalate (PET). 
     
     
         63 . The valve set forth in  claim 62 , wherein the container body consists essentially of polyethylene terephthalate (PET). 
     
     
         64 . The valve set forth in  claim 51 , wherein the valve is free from a metal material. 
     
     
         65 . The valve set forth in  claim 51 , in combination with the container body, wherein the container body comprises polyethylene terephthalate (PET). 
     
     
         66 . The valve set forth in  claim 65 , wherein the container body consists essentially of polyethylene terephthalate (PET). 
     
     
         67 . A pressurizable container for a flowable product comprising:
 a pressurizable container body configured to hold the flowable product under pressure, the pressurizable container body comprising polyethylene terephthalate (PET); and   a valve connected to the pressurizable container body for dispensing the flowable product from the container body under pressure, the valve comprising:
 a stem including a stem body defining a passage therein, and a disc at a lower portion of the stem body; 
 a seal including a seat configured to sealingly engage the disc of the stem when the valve is closed, and a neck extending from the seat and surrounding at least a longitudinal portion of the stem body, wherein the stem is movable relative to open the valve; and 
 a mounting cup configured to connect the valve to the container, wherein the mounting cup defines an opening in which the stem and the seal are received,
