  • Patent number: 9926115
    Abstract: The invention disclosed herein relates to a side press safety cap, wherein when an outer cap is rotated to opening direction with sides of the outer cap pressurized, a first rotation protrusion of an outer cap is interlocked with open guide protrusions of an inner cap, rotating the inner cap, and thereby an inner cap is opened. On the other hand, when the outer cap is rotated to closing direction, a second rotation protrusion is interlocked with close guide protrusions, rotating the inner cap and thereby the inner cap is closed. As a result, the side press safety cap is possible to be opened and closed stably.

  • Patent number: 9609936
    Abstract: Provided is a cream-type cosmetic container, which can easily discharge a highly viscous content without a separate pumping member by allowing a button part to downwardly move and then return to an original location and thus changing the internal pressure of the container body when a user pressurizes the button part, and thus can save the assembling time and the manufacturing cost.

  • Patent number: 9370790
    Abstract: The present invention relates to a shock-absorbing lower structure of an airless type dispenser, wherein a support member made of elastic material is arranged in a lower part of a piston to provide a cushioning function so as to support the lower end of the piston in the housing of the dispenser. Thus, when the piston descends and presses a housing support by the shock applied from an external source, the housing support is prevented from being separated from the housing of the dispenser. Furthermore, when content expand in volume at a low temperature, not only is a housing support or a pumping member prevented from being separated, but also the pumping member is prevented from being damaged.
