  However, in such a conventional extrusion container, in addition to the push button and the piston, a return spring, a shaft, a chuck, a presser ring, etc. must be provided, and there is a problem that the number of parts increases and the cost is increased. .

  SUMMARY OF THE INVENTION Accordingly, a first object of the present invention is to provide an extrusion container that enables a fixed amount of contents to be ejected at low cost with a small number of parts.

  A second object of the present invention is to prevent germs from coming into contact with the outside air through the spout and to keep the contents of the container hygienic at all times.

  The third object of the present invention is to regulate the amount of elastic deformation of the ejection button and to keep the content ejection volume even more constant.

  A fourth object of the present invention is to eliminate the risk of operating the contents of the container from the jet outlet to the outside by operating it by mistake.

  A fifth object of the present invention is to improve operability when, for example, a droplet is dropped.

  Therefore, an extrusion container such as a liquid drop container according to the present invention accommodates contents such as eye drops, athlete's foot medicine, and cosmetic cream, and is provided with a container for providing a content outlet, and can be attached to the container and externally operated. It is provided with an ejection button that is elastically deformed by being provided and pushed to increase the pressure in the container and ejects the contents of the container from the ejection port. In use, the pressure in the container is increased by pressing an ejection button attached to the container to increase the pressure in the container, and the contents stored in the container are ejected from the ejection port to the outside, for example, as droplets.

  A shutter part is provided in an ejection passage in the container that communicates with the ejection port, and a slit is provided in the shutter part to form a flexible piece. When the pressure in the container is increased, the movable part is pushed by the contents. It is preferable to bend the flexure piece to open the ejection passage and to cancel the flexure of the flexible piece and close the ejection passage when the pressure is restored. Moreover, it is good to form the control surface which the said ejection button elastically deformed by pushing against the said container, and it is good to provide the cover part surrounding the said ejection button. Furthermore, the ejection button may be provided at the bottom position of the container.

  According to the present invention, since it is only provided with an ejection button that is attached to the container and elastically deforms when externally operable, the number of parts is reduced by eliminating the need for parts such as pistons and return springs, and the ejection is achieved at low cost and by external operation. Since the amount of elastic deformation of the button can be made substantially equal, it is possible to provide an extrusion container that is capable of quantitative ejection of the contents and that is particularly suitable for a droplet container.

  According to the second aspect of the present invention, the shutter portion is provided in the ejection passage in the container that communicates with the ejection port. Therefore, the contents of the container are blocked from the outside by closing the shutter portion, and the outside air is passed through the ejection port. It is possible to prevent germs from touching and keep the contents of the container clean and hygienic. In use, when the pressure in the container rises by pressing the spray button, the flexible piece is bent by pressing the contents to open the ejection path, and the contents of the container are ejected from the ejection port to the outside. Can do.

  According to the third aspect of the present invention, the container is formed with a regulating surface against which the ejection button that is elastically deformed by pressing is pressed, so that the amount of ejection of the contents is further controlled by regulating the amount of elastic deformation of the ejection button. It can be kept more constant.

  According to the invention described in claim 4, since the container is provided with a cover portion that surrounds the periphery of the ejection button, the cover portion is prevented from inadvertently pressing the ejection button, and the contents of the container are mistakenly changed. It is possible to prevent ejection from the ejection port to the outside.

  According to the fifth aspect of the present invention, since the ejection button is provided at the bottom position of the container, for example, the operability when the container is inverted and used by dropping a droplet can be improved.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows a longitudinal section of an extrusion container according to the present invention.

  Reference numeral 10 in the figure is a container made up of a plastic container main body 11 and a shoulder cover 12 for storing contents such as eye drops, athlete's foot drugs and cosmetic creams. The container body 11 has a bottomed cylindrical shape, and as shown in FIG. 2 showing the bottom view, the bottom body 13 may have any number, but in the illustrated example, four communication holes 14 are provided every 90 degrees.

  An annular protrusion 15 protrudes on the outer periphery of the bottom 13 so as to surround these communication holes 14. Then, the regulating surface 16 is formed on the outer surface of the bottom portion 13 in the annular protrusion 15 by being surrounded by the annular protrusion 15. On the other hand, a short cylindrical cover 17 is provided on the outer periphery of the annular protrusion 15, and an annular groove 18 is formed between the annular protrusion 16.

  Then, the ejection button 20 is attached to the annular groove 18. The squirting button 20 is composed of a bowl-shaped button part 21 and a collar part 22 provided on the periphery thereof using a rubber material that is not affected by the contents. The flange portion 22 is inserted into the annular groove 18 and pressed by a plastic presser bush 23 that is fitted to the inner periphery of the cover portion 17. In this way, the cover 17 surrounds the periphery and is attached to the container 10, and the ejection button 20 is provided on the bottom 14 of the container 10. The ejection button 20 is provided so as to be externally operable, and is elastically deformed by being pressed and pressed against the regulating surface 16 so that the pressure in the container 10 can be increased.

  On the other hand, the shoulder cover 12 is made by integral molding using a plastic material, and has a cylindrical insertion portion 24 that fits into the upper opening of the container body 12, a flange portion 25 that protrudes outward from the upper edge thereof, and a cylindrical cover. An attachment portion 26 and a cap attachment portion 28 having a thin cylindrical shape and having a spout 27 at the tip are provided in order, and an ejection passage 30 communicating with the content spout 27 is formed therein.

  The cover attaching part 26 is fitted from above and covered with a cylindrical decorative cover 32 and is abutted against the collar part 25 and stopped. Further, the inner cap 34 is attached in the cover attaching portion 26 by being fitted from below. The inner cap 34 includes a cylindrical portion 35, a flange portion 36 provided at the lower end thereof, and a thin shutter portion 38 provided at the upper end and closing the central hole 37. As can be seen from FIG. 3 showing a plan view of the inner cap 34, the shutter portion 38 has a slit 40 that intersects the cross at the center to form a plurality of flexible pieces 41 (four in the illustrated example).

  As shown in FIG. 1, a top cap 43 is detachably placed on the outer periphery of the cap mounting portion 28. In the top cap 43, a rod-shaped stopper 44 is suspended from the top, and the tip is fitted into the spout 27. By the way, in the illustrated example, the decorative cover 32 and the top cap 43 are connected via some connecting portions 46.
