[Industrial applications]

 The present invention relates to a creamy substance dispensing container that pressurizes a stored creamy substance by deforming an elastic dome.

[0002]

[Prior Art]

 This type of elastic dome type pouring container is provided with a storage chamber for the cream-like material with the elastic dome as the top wall at the top, and a suction valve and a discharge pipe are provided between the storage chamber and the container body opening and nozzle pipe. A valve is arranged, the elastic dome is pushed in and deformed to pressurize the cream-like substance in the storage chamber, and the discharge valve is opened by this pressurized cream-like substance to be discharged from the nozzle pipe to the outside.

A large number of elastic dome shapes have been proposed and are well known, and Japanese Utility Model Laid-Open No. 156985/1988 is one such example. This publication intends to greatly reduce the number of parts, reduce the cost, and simplify the structure.

[0004]

[Problems to be solved by the device]

 As is the case with the above-mentioned publications, in most of the conventional cases, the nozzle tube was placed upright beside the elastic dome, so when pouring out, the container body was held sideways by holding it with one hand. The elastic dome is pushed in and deformed with the fingertips on the side of the hand, and the creamy substance is poured out from the sideways nozzle tube to the outside of the side.

In the case of the conventional small-sized and slender container body, that is all right, but recently, the number of medium-sized containers has increased, and the container body has become a large-diameter table-top shape that cannot be held with one hand. In this case, the nozzle tube is of course sideways, but the shape in which the nozzle tube always projects outward from the container body is an obstacle and inconvenient to handle, and the packaging at the time of distribution becomes large and cumbersome.

[0006] The present invention provides a creamy product dispensing container which is of a drawer type in which the nozzle tube is pulled out to the outside only at the time of dispensing, does not always interfere, and eliminates inconvenience in packaging and handling. ..

[0007]

[Means for Solving the Problems]

 In the creamy substance dispensing container of the present invention, a suction pipe 8 having a lower end communicating with the inside of the body 7 is vertically provided from the center of the top plate 6 to the axial center of the body 7, and is penetrated by the suction pipe 8. The inner lid 9 is fitted into the body 7 in an airtight manner so as to be able to descend, and the peripheral walls 10a and 10b provided with a negative pressure preventing mechanism 12 are partially erected from the upper surface of the top plate 6 in a double shape inside and outside. A container body 1 provided with a storage cylinder 11 having a sideways projection 22 for locking, which communicates from one side lower part of the peripheral walls 10a, 10b to the inside of the peripheral wall and crawls the top plate 6 toward one side, and the center of the top plate 6 A valve member which is provided on the upper surface of the portion and has a plate-like suction valve 13 that closes the pipe opening of the suction pipe 8 and a skirt-shaped discharge valve 14 that closes the storage cylinder 11 by pressure contact with the upper inner peripheral surface of the inner peripheral wall 10a. 2 and a peripheral edge of the lower end between the upper ends of the peripheral walls 10a and 10b are foxed to surround the upper part of the valve member 2 to form a space between the valve member 2 and the storage chamber a. A spherical elastic dome 3, a movable nozzle tube 4 which is slidably stored in the storage tube 11 and is pulled out to the outside of the body 7 at the time of pouring, and a cap-shaped nozzle tube 4 which is cut in a part of the peripheral wall. A push button which has a notch groove 15 and is rotatably provided so as to cover the elastic drum 3, and can be pushed down when the notch groove 15 is aligned with the locking projection 22 so that the elastic dome 3 can be pressed and deformed. It is composed of 5 and.

[0008]

[Action]

 In the above, the push button 5 cannot be pushed down because the lower end of the peripheral wall is always in the lock position where it rides on the locking projection 22 on the upper surface of the storage cylinder 11 as shown in FIG. Filled with material but never poured.

In pouring out, the nozzle tube 4 is pulled out to the outside, and then the push button 5 is rotated to align the notch groove 15 with the locking projection 22. Is pushed down, and thereby the elastic dome 3 is pushed and deformed to pressurize the creamy substance in the storage chamber (a). Then, the pressurized cream-like substance is forced to open the discharge valve 14 and is discharged from the storage cylinder 11 through the nozzle pipe 4 to the outside.

When the pushing down of the push button 5 is stopped after the pouring is completed, the elastic dome 3 returns to its original shape with the push button 5 due to its own elasticity, and by this return, the inside of the storage chamber (b) becomes negative pressure. Therefore, the suction valve 13 is opened, and the creamy substance in the container body 1 is sucked into the storage chamber (i) through the suction pipe 8 from the lower end communication hole of the suction pipe 8. Due to this suction, the inside of the container body 1 tends to become negative pressure, but the upper space inside the container body 1 communicates with the outside air by the negative pressure prevention mechanism 12, so the inner lid 9 moves down and responds. Prevent aging. After that, the push button 5 is returned to the original state of the lock position, and the nozzle tube 4 is pushed and stored in the storage tube 11.

The creamy product dispensing container includes a container body 1, a valve member 2, an elastic dome 3, a movable nozzle tube 4 and a push button 5. It consists of.

The body 7 of the container body 1 is a large-diameter straight cylinder having a flat top plate 6, and the body 7 has a bottom plate 16 as a separate member. The bottom plate 16 has an inner lid 9 attached thereto and also has a cream shape. After the object is stored, it is fitted into the bottom opening.

From the central portion of the top plate 6, a notch groove 17 is provided at the lower end in a circumferentially discontinuous manner, and a suction pipe 8 communicating with the inside of the body 7 is vertically hung down. The mounting cylinder 18 is erected from the upper surface of the top plate 6 around the mouth, and the inner and outer peripheral walls 10a and 10b are erected from the upper surface of the top plate 6 surrounding the mounting cylinder 18 in a doubly-shaped manner from the lower part of one side of these peripheral walls 10a and 10b. A horizontally oriented storage cylinder 11 is provided laterally so as to communicate with the inner peripheral wall 10a and crawl with the upper surface of the top plate 6 facing one side.

The top plate 6 between the inner and outer peripheral walls 10a, 10b is transferred to the upper part of the peripheral walls 10a, 10b as 6a, and as shown in the enlarged detail of FIG. 3, the rear side of the top plate 6a (right side in the drawing). ), The ventilation hole 19 of the negative pressure prevention mechanism 12 is opened. When the required ventilation gap is obtained in the fitting / engaging assembly portion, the negative pressure prevention mechanism 12 may use only this ventilation hole 19, but preferably forms a reliable ventilation passage. In this embodiment, a ventilation groove 20 is provided in the outer peripheral wall 10b above the ventilation hole 19 so that the upper space of the body 7 of the container body 1 is surely communicated with the outside air.

The lower end of the suction pipe 8 is fitted and fixed to the holding cylinder 21 on the upper surface of the bottom plate 16, and the locking projection 22 is erected on the upper surface of the base of the storage cylinder 11.

In the valve member 2, a plate-like suction valve 13 is provided at the lower end of a stepped base cylinder 23 whose lower half is reduced in diameter, and a skirt-shaped discharge valve 14 is folded back from the upper end of the base cylinder 23. In the formed shape, the lower half of the base cylinder 23 is fitted and fixed to the mounting cylinder 18, the suction valve 13 closes the upper end pipe opening of the suction pipe 8, and the skirt-shaped discharge valve 14 has an inner peripheral wall. It is pressed against the inner peripheral surface of the upper part of 10a, and the storage cylinder 11 is closed at the base part.

The elastic dome 3 has a hemispherical shape, and its lower end peripheral edge is pushed into the upward circumferential groove between the upper portions of the inner and outer peripheral walls 10a and 10b, and is fixed by an engaging ridge, and fixed downward. A space between the valve member 2 and the valve member 2 is formed in the storage chamber a.

The nozzle tube 4 is laterally stored in the storage tube 11 so as to be drawn out, and has a shape in which a rough finger rest 24 located on the top surface of the storage tube 11 is folded back from the top surface of the tip end. Is pushed into the storage cylinder 11, puts a finger against the finger rest 24 at the time of pouring, and is pulled out to the outside of the body 7 side through the finger rest 24.

The nozzle tube 4 has a frictional resistance reduced by an engaging ridge on the front end of the storage cylinder 11 and the inner circumference of the middle part and an engaging ridge on the outer circumference of the rear end of the nozzle tube 4 itself, so that the nozzle tube 4 can be easily pulled out and pushed. At the same time, we are trying to prevent it from coming out.

The push button 5 has a cap-like shape, and has a notch groove 15 notched from the lower end to the middle abdomen on one side of the peripheral wall, and a push cylinder 25 that is in contact with the top of the elastic dome 3 is provided from the back surface of the top plate. The engaging ridge on the inner circumference of the lower end engages with the engaging groove on the outer circumference of the upper part of the outer peripheral wall 10b so as not to slip out, but to be rotatable and pushed down. There is.

As shown in FIG. 2, the push button 5 always has the notch groove 15 at a position away from the storage cylinder 11, and at this position, the lower end of the peripheral wall is locked by the locking projection 22 and pushed. Although the lowering is locked, it can be pushed down when the notch groove 15 is rotated to a position that matches the locking projection 22, whereby the elastic dome 3 is pushed and deformed, and the inside of the storage chamber Can be pressed.

In the above embodiment, when the creamy substance is poured out, first the nozzle tube 4 is pulled out from the storage cylinder 11 to the outside of the side, and then the push button 5 is rotated to open the notch groove 15 in the storage cylinder. 11 Aligning with the locking projection 22 on the upper surface and pushing down, the elastic dome 3 is pushed in and deformed. Then, the creamy substance in the storage chamber (a) is pressurized, and the pressurized creamy substance pushes the discharge valve 14 to open the valve, and is discharged from the storage cylinder 11 to the outside through the nozzle pipe 4.

When the pushing down of the push button 5 is stopped after pouring, the elastic dome 3 returns to its original shape with the push button 5 due to its own elasticity, whereby the inside of the storage chamber (b) becomes negative pressure and the suction valve 13 is removed. When the valve is opened, the creamy substance in the container body 1 is sucked up into the storage chamber (i), while the suction is also attempted to make the inside of the container body 1 under negative pressure. Since the negative pressure is released by 12, the inner lid 9 is lowered to take measures.

After that, the push button 5 is returned to its original position to lock the depression, and the nozzle tube 4 is pushed into the storage cylinder 11 and stored.
