Abstract
A method for securing a pour spout fitment to a thermoplastic-coated container, wherein at least a surface of a pour spout fitment is heated remotely by a suitable heating mechanism, to a predetermined temperature. When the heated fitment surface is applied to a selected surface of an erected, thermoplastic-coated container, the heat energy is transferred to the latter surface to an extent capable of activating the thermoplastic coating thereon. Upon cooling, the fitment and the container surface are bonded together, without the need for a back-up or support mechanism, such as a mandrel or anvil.
Claims11
A method for applying an article to a thermoplastic coating of rigid laminate, the method comprising the steps of:
- a. providing an article;
- b. heating a portion of the article to a predetermined temperature by a suitable heater, wherein said predetermined temperature is below the melting point of the material of the portion of the article;
- c. placing said portion of the heated article on a portion of the thermoplastic coating without a back-up support around said latter portion, to activate said portion of the thermoplastic coating;
- and
- d. one of allowing and causing the respective portions of the heated article and the coating to cool, to thereby become bonded together.
A method for applying a pour spout fitment to a selected panel of a thermoplastic coated container, the method comprising the steps of:
- a. forming a pour spout fitment;
- b. forming, filling, and sealing the container;
- c. heating the pour spout fitment to a predetermined temperature by a suitable heater;
- d. placing the heated pour spout fitment on the selected panel of the formed and sealed container to activate the thermoplastic coating;
- and
- e. allowing the heated fitment and the activated thermoplastic coating on the panel time to cool, to thereby become bonded together.
