Referring to fig. 1, 2 and 3, an extrusion discharging container (container for short) according to an embodiment of the present invention includes a bottle body (not shown), a sealing cap 100 and a discharging head 200, the bottle body is made of an elastomer material, the bottle body can be deformed by extrusion and automatically recovers, the sealing cap 100 includes a connecting cylinder 110 and a discharging sleeve 120, the lower end of the connecting cylinder 110 is connected with the bottle body, the upper end of the connecting cylinder 110 is connected with the discharging sleeve 120, the discharging sleeve 120 is connected with the bottle body, the discharging head 200 includes a body portion 210, a sealing sliding sleeve 220 and a first sealing annular plate 230, the body portion 210 is provided with a discharging channel 211a, the upper end of the sealing sliding sleeve 220 is connected with the body portion 210, the upper end of the sealing sliding sleeve 220 is open for communicating with a (one end) of the discharging channel 211a, the lower end of the sealing sliding sleeve 220 is slidably connected with the discharging sleeve 120, the sealing sliding sleeve 220 and the discharging sleeve 120 are in interference fit, the upper end of the first sealing annular plate 230 is connected with the body portion 210, the upper end of the first sealing annular plate 230 is closed, and the discharging head 200 slides downward along the discharging sleeve 120, so that the upper end of the discharging sleeve 120 is no longer closed (the upper end of the discharging sleeve) and the discharging sleeve is communicated with the discharging channel 211 a).

The elastomer material is known material, such as TPEE, TPV, TPU, TPE, the elastomer material selected for the bottle body of the present invention needs to be selected according to actual situation, for example, as a container for cosmetics or food, needs to be selected as nontoxic material, and as a container for viscous industrial liquid raw material, can be selected as corrosion-resistant material (possibly containing harmful components); with reference to the hundred degree encyclopedia "elastomeric materials," elastomers include thermoplastic elastomers and various special saturated rubbers that are not sulfur vulcanizable, and elastomers can also be extended to the generic term of polymers having elastomeric properties. A storage cavity is formed in the bottle body and used for storing materials, and the storage cavity is communicated with the outside (the connecting cylinder 110 and the discharging sleeve 120) through an upper end opening. The materials can be viscous materials and materials containing large particulate matters, and also can be substances such as bath lotion, shampoo, hand sanitizer, facial cleanser, hair spray, astringent, cosmetic lotion, laundry detergent, liquid detergent and the like.

The sleeve is provided with an internal channel, and the internal channel is communicated with the outside through openings at two ends of the sleeve. The bottle body and the connecting cylinder 110 may be fixedly connected, detachably connected, or movably connected, for example, integrally connected (i.e., integrally formed), snap-fit connected, bonded, screwed, hot-melt connected, and slidably connected; in this embodiment, the lower end of the connecting cylinder 110 is provided with female threads 111 so that the connecting cylinder 110 is screw-coupled with the bottle body. The connection of the connector barrel 110 and the take-off sleeve 120 is as described above; in this embodiment, the connector barrel 110 and the take-off sleeve 120 are integrally formed. It should be understood that the upper end of the connecting cylinder 110 is generally closed except for the opening of the discharging sleeve 120, so as to isolate the inside and outside, prevent the leakage of the material, and also mount and fix (or connect) other components (the discharging sleeve 120, the venting sleeve 410, the second lower sealing annular plate 440, the lower sliding sleeve 130, etc.) to the base carrier. The lower end of the discharging sleeve 120 can extend into the bottle body so as to contact the material in the bottle body, or the material can directly enter the discharging sleeve 120; or the material can actively flow into the discharging sleeve 120 through an inverted container; the function of the material entering the discharging sleeve 120 can also be realized by other parts (the suction pipe 300).

It should be understood that the main body 210 includes an outlet pipe 211 provided with an outlet passage 211a and a cover 212 for installing and fixing other components (the outlet pipe 211, the sealing ring plate, the sealing sliding sleeve 220, the upper sliding sleeve 240, the second upper sealing ring plate 430, etc.). It should be understood that, in the present embodiment, the body portion 210, the sealing sliding sleeve 220 and the first sealing annular plate 230 are integrally formed, so that the three are integrally connected. The other end (discharge port) of the discharge passage 211a is used for material outflow. It should be understood that the upper end opening of the sealing sliding sleeve 220 is communicated with the (one end) feed inlet of the discharge passage 211a, and the two openings are communicated with each other, but neither opening is directly communicated with the outside. The sliding sleeve 220 is slidably connected to the discharging sleeve 120, and specifically, one of the sliding sleeve 220 and the discharging sleeve 120 can be regarded as a tube, and the other can be regarded as a (hollow) rod, the rod is inserted into the tube, and the outer diameter of the rod and the inner diameter of the tube are substantially the same or slightly different, so that the rod and the tube are slidably connected. In the utility model, the interference fit plays a role of sealing; in this embodiment, the inner wall of one component is usually abutted against the outer wall of the other component, and the diameter of the inner wall of one component is slightly smaller than that of the outer wall of the other component. The upper end of the first sealing ring plate 230 is closed (or closed), and specifically, in the present embodiment, the upper end port (opening) of the first sealing ring plate 230 is completely sealed by the body portion 210, and can not be communicated with other things, and other similar closed conditions are the same. Another description of "the discharge head 200 slides downward along the discharge sleeve 120" is that the sealing sliding sleeve 220 slides downward along the discharge sleeve 120, and at the same time, the body portion 210 and the first sealing annular plate 230 are driven to slide downward together (so that the lower end of the first sealing annular plate 230 abuts against the upper end of the discharge sleeve 120); in practice, pressing the extrusion head 200 downward, the body portion 210, the sealing sliding sleeve 220, and the first sealing annular plate 230 move downward together, specifically, in the axial direction of the discharging sleeve 120 (because the sealing sliding sleeve 220 and the discharging sleeve 120 are slidably connected). It should be understood that "the lower end of the first sealing annular plate 230 abuts against the upper end of the discharging sleeve 120, so that the upper end of the discharging sleeve 120 is closed", the lower end of the first sealing annular plate 230 abuts against the upper end of the discharging sleeve 120, either the lower end port of the first sealing annular plate 230 abuts against the upper end port of the discharging sleeve 120, so as to achieve the closing effect, or the lower end side wall of the first sealing annular plate 230 abuts against the upper end side wall (and is in interference fit) of the discharging sleeve 120, so as to achieve the closing effect.

When the container is actually used, the discharging head 200 is pulled upwards, so that the first sealing annular plate 230 and the discharging sleeve 120 are not abutted any more, namely the upper end of the discharging sleeve 120 is not closed any more, and the upper end opening of the sealing sliding sleeve 220 is communicated with the feeding hole of the discharging channel 211a again; then the bottle body is squeezed, the inner space of the bottle body is reduced, the pressure intensity is increased, so that the material flows into the discharging channel 211a along the discharging sleeve 120 (pressed), and finally the discharging hole of the discharging channel 211a flows out. After using, stop the extrusion bottle, bottle automatic recovery state, later press out stub bar 200 for first sealed annular plate 230 and ejection of compact sleeve 120 butt, the upper end of ejection of compact sleeve 120 is sealed, and the material in the bottle just can not flow (the bottle also can not be by extrusion deformation basically), and makes bottle and external isolated.

The existing pressing discharging container is provided with a pressing pump, the size of the inner space of the container is reduced after the pressing pump presses, so that a material is pumped out of a pump body through air pressure difference, but the reduced size value of the space after the pressing pump presses is fixed and is a value determined after the container is manufactured, and the value is generally small, so that when the material is viscous, if the air pressure difference is too small, the material is difficult to pump out; in addition, the press pump generally arranges the spheroid on the discharge channel 211a to form a one-way valve structure, so the space around the spheroid through the material is small, the large granule container is blocked, and the large granule container can not be pumped out with other components normally.

And the utility model discloses an extrusion ejection of compact container can prevent effectively that the mistake from extrudeing the bottle (the mistake bumps, child plays, transports the condition such as extrusion), lets out the material, and in time seals after the ejection of compact, prevents that the material evaporation from revealing, by external air pollution. And through the ejection of compact of extrusion bottle, the bottle space greatly increased that can reduce for the air pressure difference is bigger during the ejection of compact, makes things convenient for the ejection of compact of viscous material. And do not set up check valve structures such as spheroid at discharging channel 211a, ejection of compact space greatly increased, the ejection of compact of easy large granule material can not obstruct the large granule material outflow for the material that contains the large granule material can normally be extruded.

It should be especially understood that the container also has the functions of suck-back and suck-back, specifically, after the bottle body can be extruded and deformed and when the bottle body is restored to its original shape, external air can be sucked in, but since no other channel in the bottle body is communicated with the outside, air can only enter the bottle body through the discharge channel 211a (the discharge port of the discharge channel 211a, the feed port of the discharge channel 211a, the upper opening of the discharge sleeve 120, the lower opening of the discharge sleeve 120, the suction pipe 300-) in the bottle body), at this time, the residual material at the discharge port of the discharge channel 211a can be sucked into the container (the bottle body and the discharge sleeve 120) again along with air, so as to prevent the residual material from falling down and polluting the environment and reduce the waste of the material; in addition, the container does not need components made of other materials (such as steel balls and glass beads) to serve as parts of the one-way ventilation assembly 400, and the container can be made of plastics, so that the production and the processing are convenient.

Referring to fig. 1 and 2, in some embodiments of the present invention, the bottle further includes a suction pipe 300, an upper end of the suction pipe 300 is connected to a lower end of the discharge sleeve 120, the suction pipe 300 is communicated with the discharge sleeve 120, and a lower end of the suction pipe 300 extends into the bottle body.

A suction pipe 300 is arranged, so that the bottle body is extruded to discharge materials after the bottle body is not required to be inverted; specifically, after the extrusion, the material can directly enter the discharging sleeve 120 along the suction pipe 300, then enter the discharging channel 211a of the discharging head 200 from the discharging sleeve 120, and finally flow out from the discharging hole of the discharging channel 211 a.

Referring to fig. 2, 3 and 7, in some embodiments of the present invention, the sidewall of the take-off sleeve 120 is provided with an annular sealing protrusion 121, the annular sealing protrusion 121 abutting the sidewall of the sealing sliding sleeve 220, thereby providing an interference fit of the sealing sliding sleeve 220 and the take-off sleeve 120.

It will be appreciated that the annular sealing protrusion 121 may also be provided on the side wall of the sealing sliding sleeve 220, with the annular sealing protrusion 121 abutting the side wall of the take-off sleeve 120, which is a simple change in the location of the annular sealing protrusion 121. Set up annular seal arch 121, on the basis of keeping normal sealed function for sealed sliding sleeve 220 and ejection of compact sleeve 120 interference fit's area is less, prevents that area of contact between the two is too big, and frictional resistance is too big, and sealed sliding sleeve 220 is difficult for sliding relative ejection of compact sleeve 120, is difficult for carrying out pulling out stub bar 200, influences the use and experiences.
