This invention relates to a pump dispensing type container and more particularly to the manner in which the customary pump button and overcap are assembled with respect to the container and pump assembly. Orientation of the pump button with respect to the overcap has been a problem. According to this invention the pump button is so related to the overcap so that the pump button need not be initially oriented with respect to the overcap, but after the pump button and overcap have been assembled with the container and pump assembly, the overcap will be held in place in a non-dispensing position until such time as the ultimate user rotates the pump button into alignment with the overcap. At this time the pump button is in position for actuation and is held in place by its interlocking with the dispensing tube of the pump.

A method of assembling a pump button and an overcap with a container having a pump including a dispensing tube, said method comprising the steps of providing a dispensing pump button having at least one axial guide and an overcap having a bore for receiving the pump button, and at least one key member receivable in said guide channel and projecting into said bore, assembling said pump button on said dispensing tube, then telescoping said overcap onto said pump button and into position on said container with said key member radially resiliently engaging said pump button to retain said pump button on a pump assembly, said pump button being moved by said overcap to a depressed inoperative position. An overcap and pump button assembly comprising an overcap being equipped with a bore and a pump button, said overcap including an outer shell having an open end for receiving and forming an interlock with a shouldered container, and a guide sleeve within said outer shell, said pump button having a tubular body having formed therein at least one axial guide channel, said guide sleeve defining a base of a diameter of freely receive said pump button and including a radially inwardly projecting key member for reception in said guide channel; the relative diameters of said tubular body and said bore, the radial extent of said key member, and the resiliencies of said guide sleeve and said tubular body being such that when said key member and said guide channel are misaligned said pump button is forcibly engageable into said guide sleeve with said key member engaging said pump button body in radial compressed relation sufficient to retain said pump button in said guide sleeve in a depressed, inoperative position while permitting manual rotation of said pump button within said guide sleeve to align said guide channel with said key member.
