Referring to fig. 1 to 4, the present invention provides a liquid container convenient for screwing out a press head, comprising: pressing the pump body 100; a locking cap 200 connected to the upper end of the pressing pump body 100, and having a pressing head 300 screwed thereto; a screw cap 400 rotatably fitted around the exterior of the pressing pump body 100 and located between the pressing pump body 100 and the locking cap 200; the bottle 500 is screwed to the screw cap 400, a rotation limiting mechanism 600 is disposed between the bottle 500 and the pressing pump body 100, and the rotation limiting mechanism 600 can limit the pressing pump body 100 to rotate relative to the bottle 500 so that the pressing head 300 can be screwed out of the locking cap 200.

When the press head 300 needs to be screwed out of the lock cap 200 in the liquid container with the structure, the rotation limiting mechanism 600 arranged between the bottle body 500 and the pressing pump body 100 can prevent the press head 300 from driving the lock cap 200 and the pressing pump body 100 to rotate together relative to the screw cap 400, and the rotation limiting mechanism 600 can also prevent the press head 300 from driving the lock cap 200, the screw cap 400 and the pressing pump body 100 to rotate together relative to the bottle body 500, so that the press head 300 can rotate relative to the lock cap 200 and be switched to a screwing-out state, and the liquid container can normally work to discharge liquid in the bottle body 500.

It should be noted that the locking cap 200 may be fixedly connected to the upper portion of the pressing pump body 100, or may be connected to the pressing pump body 100 through another limiting structure, so that the locking cap 200 cannot rotate counterclockwise continuously relative to the pressing pump body 100, and the pressing head 300 can be screwed out relative to the locking cap 200.

Referring to fig. 1, in some embodiments of the present invention, the rotation limiting mechanism 600 includes a first rotation limiting structure 610 disposed between the outer peripheral wall of the bottle mouth of the bottle 500 and the screw cap 400 and a second rotation limiting structure 620 disposed between the screw cap 400 and the pressing pump body 100, the first rotation limiting structure 610 can limit the counterclockwise rotation angle of the screw cap 400 with respect to the bottle 500, and the second rotation limiting structure 620 can limit the counterclockwise rotation angle of the pressing pump body 100 with respect to the screw cap 400. It should be noted that after the screw cap 400 is screwed on the bottle mouth of the bottle 500 clockwise, the screw cap cannot rotate counterclockwise relative to the bottle 500 to separate from the bottle 500 under the action of the first rotation limiting structure 610, when the button 300 is screwed out counterclockwise relative to the locking cap 200, the locking cap 200 and the pressing pump body 100 have a tendency to rotate counterclockwise relative to the bottle 500, and the second rotation limiting structure 620 limits the counterclockwise rotation angle of the pressing pump body 100 relative to the screw cap 400, so that the button 300 can rotate counterclockwise to completely separate from the locking cap 200, thereby realizing the normal up-and-down movement of the button 300. Compared with the way of directly arranging the rotation limiting mechanism 600 between the bottle 500 and the pressing pump body 100, the rotation limiting mechanism 600 composed of the first rotation limiting structure 610 and the second rotation limiting structure 620 has the advantages that the difficulty of production, processing and assembly of the rotation limiting mechanism 600 is small, and particularly the requirement on assembly is low.

It should be noted that the first rotation limiting structure 610 can limit the counterclockwise rotation of the screw cap 400 relative to the bottle 500 by a small angle, and the screw cap 400 cannot rotate counterclockwise relative to the bottle 500. Similarly, the second rotation limiting structure 620 can limit the counterclockwise rotation angle of the pressing pump body 100 relative to the thread cover 400, so that the pressing pump body 100 cannot rotate counterclockwise relative to the thread cover 400 at all, or the pressing pump body 100 cannot rotate counterclockwise continuously only by a small counterclockwise rotation angle relative to the thread cover 400.

Referring to fig. 3 and 4, in some embodiments of the present invention, the first rotation limiting structure 610 includes a first rotation stopping tooth 611 disposed on an outer circumferential wall of the mouth of the bottle body 500 and a second rotation stopping tooth 612 disposed on an inner circumferential wall of the screw cap 400 and capable of engaging with the first rotation stopping tooth 611. It should be noted that when the screw cap 400 tends to rotate counterclockwise relative to the bottle mouth of the bottle body 500 and disengage from the bottle body 500, the second rotation stop tooth 612 engages with the first rotation stop tooth 611 to prevent the screw cap 400 from rotating continuously relative to the bottle body 500, so as to ensure that the screw cap 400 does not fall off from the bottle body 500 when the press head 300 is rotated counterclockwise.

Referring to fig. 3, in some embodiments of the present invention, the first rotation stopping tooth 611 is provided with a first guiding arc-shaped surface 613, the head end of the first guiding arc-shaped surface 613 is connected to the outer circumferential wall of the bottle mouth of the bottle body 500 in the direction of clockwise rotation of the screw thread cover 400 relative to the bottle body 500, a first stopping surface 614 is connected between the end of the first guiding arc-shaped surface 613 and the outer circumferential wall of the bottle mouth of the bottle body 500, and the second rotation stopping tooth 612 is an elastic clamping strip which can move along the first guiding arc-shaped surface 613 and elastically abut against the first stopping surface 614. It can be understood that, when the screw cap 400 is screwed on the mouth of the bottle body 500 in the clockwise direction, the elastic clip strip can move along the head end of the first guiding arc-shaped surface 613 to the tail end, the elastic clip strip passes over the tail end of the first guiding arc-shaped surface 613 and then recovers elastic deformation to abut against the first stop surface 614, and when the press head 300 rotates counterclockwise to drive the screw cap 400 to have a tendency to rotate counterclockwise, the first stop surface 614 prevents the screw cap 400 from rotating counterclockwise, so that the screw cap 400 is kept set on the bottle body 500. The first rotation limiting structure 610 is simple in structure and convenient to use. The elastic clip strip may be integrally injection-molded with the screw cap 400, and the first rotation stopping teeth 611 may be integrally injection-molded with the bottle body 500.

Referring to fig. 4, in some embodiments of the present invention, in order to balance the stress of the screw cap 400 and prevent the situation of tilting of the stress of the screw cap 400, a plurality of elastic clamping strips are circumferentially distributed on the inner peripheral wall of the screw cap 400, two first rotation stopping teeth 611 which are arranged back to back are arranged on the outer peripheral wall of the bottle mouth of the bottle body 500, and an angle limiting interval which can contain one first rotation stopping tooth 611 is defined between two adjacent elastic clamping strips.

The laterally extending annular portion 110 is in a thin plate shape, and when the screw cap 400 is mounted at the opening of the bottle body 500, the latch 622 and the spline 621 are combined to prevent or limit the pump body 100 from being pressed to rotate counterclockwise relative to the screw cap 400 under the action of the first rotation limiting structure 610.

Referring to fig. 2 and 4, in some embodiments of the present invention, the inner top surface of the thread cover 400 is provided with a plurality of rotation blocking teeth 623 protruding downward, the rotation blocking teeth 623 are circumferentially distributed at intervals, a tooth space 621 is defined between two adjacent rotation blocking teeth 623, and the latch 622 is disposed on the upper end surface of the side extension ring 110 and is elastically latched within one tooth space 621 thereof. It will be appreciated that the thin plate-like side extending annular portion 110 has a tendency to elastically deform in an upward direction, and the latch 622 is upwardly engaged in one of the slots 621 by the side extending annular portion 110.

Referring to fig. 2, in some embodiments of the present invention, in order to prevent the latch 622 from being locked in the tooth space 621 when the screw cap 400 is assembled with the pressing pump body 100, the rotation preventing teeth 623 are provided with a second guiding arc-shaped surface 624, in a direction in which the pressing pump body 100 rotates clockwise relative to the screw cap 400, a head end of the second guiding arc-shaped surface 624 is connected to an inner top surface of the screw cap 400, a second stopping surface 625 is connected between a tail end of the second guiding arc-shaped surface 624 and the inner top surface of the screw cap 400, the latch 622 is provided with a third stopping surface 626 matched with the second stopping surface 625, and the latch 622 can move along the second guiding arc-shaped surface 624 and align the third stopping surface 626 with one second stopping surface 625. It can be understood that, when the screw cap 400 is screwed on the mouth of the bottle body 500 clockwise, if the latch 622 abuts against the second guiding arc-shaped surface 624 and the screw cap 400 is further rotated clockwise, the latch 622 can move to the end along the head end of the second guiding arc-shaped surface 624, the latch 622 passes the end of the second guiding arc-shaped surface 624 into the tooth groove 621, and when the pressing pump body 100 is driven to rotate counterclockwise by the counterclockwise rotation of the pressing head 300, the third stop surface 626 abuts against the second stop surface 625 and prevents the pressing pump body 100 from rotating counterclockwise relative to the screw cap 400, and the above second rotation limiting structure 620 has a simple structure and is convenient to use.

In some embodiments of the present invention, in order to prevent the screw thread cover 400 from tilting relative to the pressing pump body 100, the latch 622 is provided in a plurality, and the plurality of latches 622 are circumferentially spaced around the upper end surface of the side extension ring 110.
