[Industrial application] The present invention relates to a creamy substance dispensing container.

[0002]

[Prior art]

【Problems to be solved by the invention】 For example,
The creamy substance pouring container described in Japanese Patent No. 71 has a cylinder and a mounting cylinder that stand up from the top surface of the top wall attached to the upper end of the body of the lower end face opening in an inner / outer double cylinder shape, and the top wall part surrounded by the lower end of the cylinder. A communication cylinder is erected from a container body having a suction hole formed therein and a cylindrical piston fitted to the inner surface of the upper part of the cylinder, and an inverted L-shaped nozzle lower part is fitted to the outer surface of the communication cylinder.
Further, the lower end of the outer cylinder, which hangs from the inner cylinder fitted to the outer surface of the upper portion of the nozzle through the outward flange-shaped wall, is fitted onto the inner surface of the upper portion of the mounting cylinder in a vertically slidable and non-slip-out manner. Push-down head, a suction valve attached to the inner bottom of the cylinder, a discharge valve attached to the tip of the nozzle, a coil spring for urging the push-down head upward, and a lower inner surface of the body. It is formed with a bottom plate fitted so that it can be raised by negative pressure in the body.

By the way, normally, the smaller the number of members constituting the container, the more the number of steps required for molding and the assembling of the members can be surely reduced, and the container can be formed at low cost. Since it is composed of eight members such as a bottom plate and the like, there has been a drawback that molding and assembling are troublesome and the cost is high.

The present invention aims to reduce the number of members by making the members constituting the nozzle, the pressing head, etc., into an integrally molded product, and to facilitate the molding and assembly.

[Means for Solving the Problems] Body 2 having an opening at the lower end face 2 Inward flange-like wall 3 attached to the upper end of cylinder 2
And a short peripheral wall 6 is hung from the inner peripheral edge of the inward flange-shaped lateral wall 5 attached to the upper end of the cylinder.
A container body 1 in which a mounting peripheral wall 7 is erected from the upper surface of the inward flange-shaped wall 3, and a mounting cylinder 10 in which a lower portion is fitted to the outer surface of the mounting peripheral wall 7 are provided with a cap-like portion 11 protruding upward from the mounting cylinder. It is possible to push down the cap-shaped portion 11 portion above the split groove 12 which is circumferentially provided below the shaped portion, leaving the front portion, from the middle portion of the front face to protrude into the upper portion of the mounting cylinder 10. As the push-down head 14, the lower part of the inner cylinder portion 15 which is vertically extended from the lower surface of the push-down head and communicates with the spout cylinder 13 is vertically slidably fitted to the inner surface of the short peripheral wall 6, and the split groove is also provided. 12 An operating member 9 in which both ends are extended and a pair of left and right vertical split grooves 16 and 16 are formed in the front part of the mounting cylinder 10, and a tubular shape which is fitted in a watertight and vertically slidable manner on the upper inner surface of the cylinder 4. A communication cylinder 22 is erected from the inner surface of the piston 20 through an inward flange 21, and the upper end opening of the communication cylinder is closed by a discharge valve plate 23 integrally attached. A piston member 19 which is closed and has the communication cylinder 22 fitted to the inner surface of the inner cylinder portion 15, and a coil which is fitted to the outer surface of the inner cylinder portion 15 and urges the pressing head 14 and the piston member 19 upward. The spring 25 and the bottom plate 26 are fitted to the inner surface of the lower portion of the body 2 so as to be watertight and capable of rising by negative pressure in the body.

[0006]

In the container of the present invention, the cap 29 and the mouth cap 28 are removed from the state shown in FIG. 1, and the piston member 19 is pushed down against the bias of the coil spring 25 via the push-down head 14, and the cream in the cylinder 4 is pushed. Although the object is pressurized and discharged from the pouring cylinder 13, the operating member 9 of the present invention has a structure in which the front end of the upper end of the mounting cylinder 10 and the front part of the pressing head 14 are integrally connected. If the piston member 19 is pushed down via 14, the piston member should tilt rearward and become impossible or difficult to descend in the cylinder 4. However, the piston member 19 is circumferentially provided below the cap-like portion 11 while leaving the front portion. Groove 12 ends are extended to form a mounting cylinder
Since a pair of left and right vertical split grooves 16, 16 are formed in the front portion, when the piston member 19 is pushed down, together with the cap-shaped portion 10 between the front portions of the split groove 12, the mounting tube between the vertical split grooves 16, 16. Since the 10 part is elastically bent, the piston member 19 can be slid up and down without tilting.

Further, when the pushing down of the pushing head 14 is released at the time when the pouring of the creamy substance is completed, the coil spring 25 elastically restores, so that the pushing head 14 and the piston member 19 return to their original positions. Then, the creamy substance in the body 2 is sucked up into the cylinder 4, and the body 2 is sucked up by the suction.
The internal negative pressure is eliminated by raising the bottom plate 26.

[Effect of the Invention] The present invention is configured as described above, and is provided with a cap-shaped portion 11 protruding upward from the mounting cylinder 10 and a split groove 12 circumferentially provided below the cap-shaped portion leaving a front portion. Upper cap 11
Since the part is the push-down head 14 that can be pushed down into the upper part of the mounting cylinder 10, the operating member 9 constituting the mounting cylinder 10, the pressing head 14 and the like can be integrally molded, and the cylindrical piston 20
Since the discharge valve plate 23 is integrally attached to the upper end of the communication cylinder 22 standing upright from the inside through the inward flange 21 to form the piston member 19, the container body 1, the operating member 9, the piston member 19, the coil spring 25, the bottom plate. A container can be manufactured with a minimum of 26 members, and therefore the number of steps required for molding and assembling the members can be significantly reduced, and the cost can be reduced, and the operating member 9 can be formed as an integrally molded product having the above-mentioned configuration. Then, the pressing head 14
When the piston member 19 is pushed down via the piston member, the piston member should tilt rearward to make it impossible or difficult to descend in the cylinder 4. However, in the present invention, both ends of the split groove 12 are extended to form the mounting cylinder 10 front. Since a pair of left and right vertical split grooves 16, 16 are formed in the part,
When the piston member 19 is pushed down, it is possible to elastically bend the cap-shaped portion 11 between the front portions of the split grooves 12 and the mounting cylinder 10 portion between the vertical split grooves 16 and 16, so that the piston member 19 is not hindered. Since the discharge valve plate 23 is attached to the upper end of the communication tube 22 of the piston member 19, the inside of the body 2 becomes negative pressure due to the discharge of the creamy substance, and the body 13 is discharged from the spout cylinder 13 The outside air is not sucked into the inside of 2 and does not hinder the rise of the bottom plate 26.
