Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a creamy substance discharge container.

"Prior Art" As a creamy substance discharge container of this kind, a sliding bottom plate that rises due to negative pressure inside the container is fitted in the lower part of the container body at the bottom end opening, and at the top of the container body BACKGROUND ART There is known a container provided with a pump having a nozzle so that the cream in the container can be sucked into the pump chamber by the operation of the pump and the cream in the pump chamber can be discharged from the nozzle.

[Problems to be solved by the invention] The conventional creamy product discharge container is filled with the creamy product after the pump forming member is mounted and the container is inverted and then opened from the opening at the lower end of the body, The sliding bottom plate is fitted to. However, in this case, since the outer circumference of the sliding bottom plate is provided so as to be in airtight contact with the inner surface of the body, air is likely to remain between the filled creamy product and the sliding bottom plate. Air enters the pump chamber and is discharged in a pressurized state together with the creamy material, and the discharged cream is scattered. Further, since the sliding bottom plate is provided so as to rise in the body portion by the negative pressure inside the container due to the reduction of the creamy substance and eliminate the negative pressure state, it is not fixed to the body portion, so When the inside of the body is pressurized due to contact with the body, the sliding bottom plate may fall out of the body.

 The present invention aims to eliminate such drawbacks.

"Means for Solving the Problem" The sliding bottom plate 25 is fitted in the lower part of the body part of the container body at the lower end opening so as to be able to rise, and a pump with a nozzle 10 is attached to the upper part of the container body to operate the pump. In a creamy substance discharge container provided to suck a creamy substance in a container into a pump chamber and to discharge it from a nozzle, an air bleeding groove 6 is vertically provided on the inner surface of the lower part of the body part of the container and the lower end of the body part is formed. A leg cylinder 7 having a diameter larger than that of the trunk portion is hung from the bottom portion, and the bottom surface of the sliding bottom plate 25 is supported by an inward flange 32 of a peripheral wall 31 which is watertightly fitted to the lower end portion of the leg cylinder. Support tube 33
A bottom lid 30 for standing up was attached.

[Operation] When the cap 35 and the nozzle palate 20 are removed and the top surface of the head 11 with the nozzle 10 is pushed down against the container body 1,
The discharge valve 17 opens and the cylindrical piston 12 descends in the cylinder 5. Next, when the head 11 is released, the head 11 rises due to the bias of the spring 19, but at this time the discharge valve 17 rises while being closed, so the suction valve 18 at the bottom of the cylinder opens and the cream inside the container enters the cylinder chamber. Inhale. When the head is stopped rising, the suction valve 18 is closed, and when the head is lowered, the discharge valve is opened and the creamy product in the cylinder is discharged from the nozzle 10. Sliding bottom plate 25 by reducing the negative pressure by reducing the amount of cream in the container
Rises to eliminate the negative pressure condition.

"Example" 1 is a container body, which has a body portion 2 with an opening at the lower end surface, and a cap fitting tube 3 is formed into an inner-outer double-tubular shape from an upper end of the body portion through a narrow upward step. And an inward flange 4 is attached to the lower end of the inner cylinder, and the cylinder 5 is erected from a slightly outer upper surface of the inner peripheral edge of the flange. An appropriate number of air bleeding grooves 6 are vertically provided on the inner surface of the lower part of the body, and a leg cylinder 7 having a diameter larger than that of the body is hung from the lower end of the body. The lower end of the leg cylinder is formed into an inner-outer double cylinder through a groove 8 having an opening on the lower surface, and the inner cylinder 7a is shorter than the outer cylinder 7b.

A head 11 having a nozzle 10 is vertically movably fitted to the upper part of the container body to form a pump. The head hangs a cylindrical piston 12 formed so as to be vertically movable into the cylinder 5 from the lower surface of the top wall 14 through a piston leg cylinder 13, and also has a tapered portion 15 that expands downward from the outer circumference of the top wall. The sliding cylinder 16 is fitted to the inner surface of the cap fitting cylinder 3 via the interposition. Nozzle 10
Makes the nozzle hole 10a communicate with the upper part inside the piston leg cylinder 13 and projects obliquely outward. A known cylindrical check valve is fitted into the cylindrical piston to form a discharge valve 17, and a similar cylindrical check valve is fitted into the bottom of the cylinder 5 to form a suction valve 18. are doing. Reference numeral 19 is a coil spring for pushing up the head, and 20 is a palate fitted to the tip of the nozzle.

A sliding bottom plate 25 is fitted into the lower portion of the container body. A peripheral wall 27 is attached to the outer periphery of the bottom wall plate 26 of the sliding bottom plate, and the upper and lower end portions of the peripheral wall are curved so that these end portions can be hermetically pressed against the inner wall surface of the body. The sliding bottom plate 25 is
After filling the creamy substance into the container body 1, it is performed in an inverted state of the container body. However, since the air bleeding groove 6 is provided as described above, it is between the sliding plate and the creamy substance when the sliding plate is fitted. It can be fitted without leaving air.

The bottom cover is placed inside the leg cylinder 7 that is hung vertically from the lower end of the container body.
Fit 30. The bottom lid is a watertight fit to the lower end of the leg cylinder, the support cylinder 33 is erected from the inward flange 32 of the peripheral wall 31,
The lower surface of the bottom wall plate 26 of the sliding bottom plate 25 is supported by the upper end surface of the support cylinder. The peripheral wall 31 has a double cylinder shape as shown in the drawing, and the outer cylinder 31a is fitted into the groove 8 of the leg cylinder 7, and the outer surface of the inner cylinder 31b is fitted to the inner surface of the inner cylinder 7a of the leg cylinder. You should let me.

In addition, 35 is a cap. Except for the spring 19, each member is made of synthetic resin.

[Advantage of the Invention] The present invention is configured as described above, and has a pump with a nozzle on the upper part of the container body, the creamy substance inside the container is sucked into the pump by the operation of the pump, and the creamy substance inside the pump In a creamy product discharge container provided so as to eliminate the negative pressure caused by the decrease of the creamy product in the container body when the sliding bottom plate fitted in the lower part of the container body rises. Since the air bleeding groove 6 is vertically provided in the lower portion of the container body, air is not left between the sliding bottom plate 25 and the creamy material in the container body, and As in the above-mentioned conventional example, there is no possibility that the pressurized air is ejected together with the cream-like substance and the cream-like substance is scattered, and the air bleeding groove 6 is formed. Even if some creamy substance exudes through the groove, The bottom lid 30 is fitted to the leg cylinder 7 having a diameter larger than that of the body portion hung from the lower end portion of the container body, and the bottom lid peripheral wall 31 is water-tightly fitted to the lower end portion of the leg cylinder and the bottom thereof is Since the support cylinder 33 is erected from the inward flange 32 of the lid peripheral wall, it is possible to prevent the above-mentioned bleeding from oozing further to the outside of the container. Even if the body of the container body is pushed by the contact between the body and the pressure inside the body, the sliding bottom plate 25 can be prevented from falling out of the body of the container body. Furthermore, since the bottom lid 30 does not close the support cylinder 33, if the slide bottom plate does not rise for some reason regardless of the negative pressure inside the container, the slide bottom plate is passed through the support cylinder with a rod-shaped object. It is convenient to push up 25 to eliminate the above-mentioned negative pressure condition, and to confirm the remaining amount of the creamy substance in the body by observing the position of the sliding bottom plate in the body.
