Description

Stepless control device for pressing stroke of container

Technical Field

The utility model relates to a press stroke stepless control device of a container.

Background

Containers currently used for filling liquids such as shampoos, hand creams, dishwashing liquids, etc., generally contain: the bottle body is provided with a bottle mouth at the top end; and the extruding device comprises a pressure pump and a fixed cover body, wherein the fixed cover body is pivoted on the outer edge of the pressure pump and used for fixing the pressure pump on the bottle opening, a pipe body connected with the bottom end of the pressure pump extends into the bottle body, and a pressing head is connected with the top end of the pressure pump. Therefore, the user can press and move the pressing head downwards to enable the pressing head to move downwards for a stroke, and then the liquid filled in the bottle is extruded outwards along with the pressing head by the aid of the pressure pump, so that the liquid can be used by the user.

However, different users have different liquid amounts in the container according to their usage habits or requirements, and in the case of hand washing cream and detergent, the required amount of shampoo or rinse for adults is usually larger than that for children and long-hair users. However, the current container cannot limit or adjust the pressing stroke of the pressing head, so that when the container is used, a user usually presses the pressing head to the end, which may cause waste due to excessive amounts of hand washing cream, detergent, shampoo or hair rinse, and thus taiwan patent No. M542625 discloses a pressing bottle flow rate adjusting device, comprising: the sleeving body is sleeved with a pipe body into the sleeving space through the gap, so that the sleeving body is sleeved on the pipe body and is arranged between the pressing head and the bottle cap, and the pressing stroke of the pressing head is limited by the thickness of the sleeving body so as to adjust the single pressing flow.

However, the push bottle flow rate control device disclosed in the above-mentioned M542625 patent has the following disadvantages:

1. because each set of the set body can only reduce the stroke of the thickness of one set body of the pressing head, the user must match with several set bodies with different thicknesses to assemble the required height, and the requirement of stepless adjustment cannot be met.

2. If a larger stroke needs to be adjusted, a plurality of sleeving bodies need to be mutually stacked and buckled on the pipe body, so that the use is very troublesome and inconvenient.

3. The sleeve body is buckled on the tube body, and is easy to fall off and lose when in use.

The inventor of the present invention has made a study and innovation in view of the above, and discloses a pressing stroke stepless control device for a container of the present invention.
