Description

Indenter with foaming function

The present invention relates to an indenter, and more particularly to an innovative indenter type designer having a foam generating function.

According to the daily use of containers such as bottles and cans to accommodate creamy liquids such as hand lotion and shampoo, it is quite common. In the past, the opening of the container is usually sealed with a cover to prevent leakage of liquid, but In order to facilitate the user to take the liquid in the container, the design of installing a pressing head at the opening of the container appears, so that the user can draw the liquid in the container by pressing without repeatedly opening and closing the cover.

However, in the conventionally used indenter, it is usually only the action of drawing the liquid by the piston member inside the pipe body of the indenter, and the indenter itself does not have any additional function, so when the liquid is extruded by the indenter After that, it is still necessary for the user to shake back and forth with the hands (for example, shampoo) to mix with air to generate foam, and to be uniform and meticulous. It can be seen that the functionality of the conventional conventional indenter is obviously difficult. In order to meet the diversified use requirements, and the convenience and practicability of the products are still unsatisfactory, in the face of the competition of many inferior products, how to create a new indenter structure to enhance the competitiveness of the products, the relevant industry must work hard The goals and direction of research and development breakthroughs are also expected by users.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation of the above objectives, the inventor has finally obtained the practical invention.

The main object of the present invention is to provide an indenter having a foam generating function; the problem to be solved is to improve the problem of the conventional indenter; the indenter of the present invention can be matched The invention is characterized in that the container is provided with a liquid material; the technical feature of the present invention is mainly that the pressure head system comprises a main body, which comprises a main body supporting a piston member and a pressing joint connected to the main body. And a liquid suction portion connected to the lower side of the main body, wherein the pressing portion includes an outlet pipe portion having a guiding port, and when the pressing portion is reciprocally pressed, the piston member can be used in the container. The liquid substance is sucked by the liquid suction part, and the liquid substance accumulated in the piston member is taken up to the liquid discharge pipe part; a low pressure suction force generating element is arranged in a ring-shaped solid state at a predetermined position in the liquid discharge pipe part; The radial port is formed in the axially penetrating communication state of the low-pressure suction generating element, and is configured to pass through the guiding port and then collect the low-pressure suction generating component when the liquid material is drawn to the liquid discharging pipe portion. After the diameter reduction port is extruded, the flow rate of the liquid material is increased and the pressure is lowered, thereby generating a low pressure attraction to the periphery; at least one air guiding port is opened at a predetermined position of the liquid discharge pipe portion, and is located at the low pressure suction generating element. The side of the reduced diameter port is configured to allow the air outside the liquid outlet portion to be sucked into the liquid discharge pipe portion through the air guiding port while the liquid material is extruded from the reduced diameter port to generate a low pressure attraction force, so that the air The liquid material can be mixed with the liquid material, so that the liquid material extruded from the liquid discharge pipe portion is foamed; thereby, the unique and innovative design makes the present invention have the function of extracting the liquid material in addition to the prior art. The additional function of the foam is generated, so that the user only needs to press the pressing portion to make the extruded liquid material foam, and no additional squeezing action is required to generate the foam, so that the liquid material can be used more. It is even and meticulous, and it can also make it easier to use, so as to achieve a lot of practical benefits such as greatly improving the convenience, practicality and satisfying the diverse needs of users.
