Claim 7, Wang discloses wherein an inner sleeve (FIG 2) cooperating with the pump rod is disposed on the piston, the sealing ring is disposed at a lower end of the inner sleeve, the inner sleeve cooperates with the upper limiting stand through an upper end surface of the inner sleeve and is in sealed connection when the upper limiting stand presses downwards the upper end surface of the inner sleeve, and an upper end of the inner sleeve is provided with a convex ring protruding inwards and interfering and cooperating with an outer side wall of the pump rod.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 3 is rejected under 35 U.S.C. 103 as being unpatentable over Wang.
Claim 3, Wang discloses the claimed invention except for gasket is made of same material as lock bottle cap. It would have been obvious to one having ordinary skill in the art at the time the invention was made to make the gasket and cap out of the same material to improve the ease with which it can be recycled, since it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious engineering choice. Selection of a known material based on its suitability for its intended use supported a prima facie obviousness determination (MPEP 2144.07).
Claim(s) 8-9, 10 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Wang as applied to claim 1 above, and further in view of Li et al. (CN 214932184 U).
Claim 8, Wang substantially discloses the apparatus as claimed above but is silent on wherein the spring is integrally formed by injection molding.
Li teaches wherein the spring is integrally formed by injection molding ([0010]).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device of Wang with spring as taught by Li in order to provide an injection molded spring.
Claim 9, the modified apparatus of Wang teaches wherein the spring is of a hollow structure that is open at both ends, comprising an upper cup body, a lower cup body (Li: 52, 43; FIG 1), and a straight cylinder body connecting the upper cup body and the lower cup body, all of which are elastic; the upper cup body and the lower cup body are symmetrical and shaped into a cup shape; each of inner diameters of the upper cup body and the lower cup body gradually expands from one end close to the straight cylinder body to the other end, and an outer protrusion is disposed at one end of each of the upper cup body and the lower cup body away from the straight cylinder body.
Claim 10, the modified apparatus of Wang teaches wherein the spring is of a hollow structure that is open at both ends, comprising an upper bowl body and a lower bowl body (Li: 52, 53; FIG 1), both of which are elastic; the upper bowl body and the lower bowl body are symmetrical up and down, and the upper bowl body is shaped into a bowl-shaped structure with a large upper end and a small lower end, and the lower bowl body is shaped into a bowl-shaped structure with a small upper end and a large lower end; and the lower end of the upper bowl body and the upper end of the lower bowl body are connected to each other.
Claim 10, Wang substantially discloses the apparatus as claimed above but is silent on wherein a buckle capable of preventing the press head from being pressed downwards is detachably connected to the pump rod between the lock bottle cap and the press head, and the buckle is made of the same plastic as the lock bottle cap.
Li teaches locking buckle (10; FIG 1).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device of Wang with buckle as taught by Li in order to provide a limiting piece to limit movement.
Claim(s) 11 are rejected under 35 U.S.C. 103 as being unpatentable over Wang as applied to claim 8 above, and further in view of Liang et al (CN 114394327 A).
Claim 11, Wang substantially discloses the apparatus as claimed above but is silent on wherein the spring is an elastic plastic ring-shaped member with an opening in a side surface, and a reinforcing rib is disposed on an outer side surface of the elastic plastic ring-shaped member.
Liang teaches wherein the spring (6; FIG 4) is an elastic plastic ring-shaped member with an opening in a side surface, and a reinforcing rib is disposed on an outer side surface of the elastic plastic ring-shaped member.
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the device of Wang with spring as taught by Li in order to provide an more stable spring.
