Description

The present invention is a cosmetic product such as various cosmetic creams, facial cleansing packs, hairdressing pomades, or other highly viscous substances such as shampoos, rinses and other various hygiene products, or mayonnaise or ketchup. The present invention relates to a container suitable for containing various paste-like seasonings such as white sauce and a viscous or fluid substance such as food.
Above all, when taking out the contents from a hollow container containing various viscous or fluid substances as described above, a dispensing pump or special tool having a complicated structure as before is used. The present invention relates to a dispensing container that can dispense a necessary amount from the inside of a hollow container without being used and without getting hands dirty.

Various types of highly viscous cosmetic substances such as cosmetic creams and hairdressing pomades, or various pasty foods such as mayonnaise and white sauce, have been conventionally used in wide-mouthed containers made of glass, etc. It is generally housed and sealed, and in order to take out the contents from these containers and use them, an operation such as rotating a screw lid or other lid that seals the opening is used. After opening, the contents are attached to the fingertips and taken out, or they are scooped out using a tool such as a spoon.
In addition, if the above-mentioned various viscous or fluid substances are contained in a hollow container having a tubular shape or other shape made of a soft material that can be pressed and deformed, cover the container with a lid. A method is employed in which the contents are poured out and used by pressing and deforming the body of the container after opening.

However, if the contents contained in a wide-mouthed container like the former are taken out with a fingertip or spoon, etc., the dirt on the fingertip or the material adhering to the spoon should be washed away after use. Also, it is difficult to accurately extract the required amount.
In addition, tools that are contained in soft containers such as the latter do not stain tools, but as the amount of contents decreases, it becomes increasingly difficult to squeeze the contents by pressing the container. It becomes.
When the contents stored in the container as described above are used, the space in the container becomes wider and the area where the contents come into contact with the air becomes larger. However, it is very difficult to prevent such contents from being altered.

  Therefore, as a container in which such inconvenience is eliminated, a container that has been widely used is generally used in a mouth and neck of a hollow container that contains a liquid material having high viscosity such as the shampoo described above. By attaching an extraction device composed of a reciprocating cylinder, and performing an operation of pressing the pressing head portion of the extraction device with a fingertip, etc., and reciprocating the piston inside the cylinder, Various pouring containers are widely used that pressurize the sucked liquid and pour it out from the nozzle port of the pouring device.

By the way, in the extraction container equipped with such an extraction apparatus, it is very convenient that no extraction tool is required to take out the contents and use, and the hand is not soiled. However, since such a pouring device is composed of many parts and its structure is somewhat complicated, it is very difficult to reduce the manufacturing cost of the pouring device.
Therefore, compared to such a conventional pouring device, an inexpensive pouring device that can reduce the manufacturing cost by using a simpler structure, fewer parts, and less labor for assembly is used. It is hoped that the existing dispensing container will appear.

  As an inexpensive dispensing container in which the dispensing apparatus having such a structure is used, as shown in Japanese Utility Model Laid-Open No. 53-88428, a lid is provided in a cylindrical container body containing the contents. A container in which a penetrating pressing part and a piston having a discharge pipe erected are fitted so as to be movable up and down, and the contents can be poured out through the discharge pipe by pressing the pressing part and pushing down the piston, As shown in Japanese Utility Model Laid-Open No. 61-175165, the lid-shaped upper part is slidably fitted into a lower-cylindrical body serving as a pinton in a lid-like upper cylindrical body capable of accommodating contents. A discharge port that can be extruded on the top plate portion of the cylindrical body is erected and opened, and a container or the like that allows the contents to be poured out from the discharge port by pressing and entering the piston-like lower cylindrical body. Are known.

  However, the former device is not provided with a protector that protects the nozzle portion of the discharge pipe penetrating the lid, a stopper that fixes the discharge tube inoperably, and the latter device does not have a discharge port. Since the opening is sealed with a screw lid, the contents will not be inadvertently discharged, but the lid must be twisted to open and close, so the opening and closing operation is troublesome, Since a stopper for fixing the movement of the piston is not provided, the contents of any of these dispensing containers may be inadvertently pushed out if any pressure is applied to the pressing portion or the piston.

  Therefore, the applicant has improved these problems and fitted the inner lid to the inner surface of the upper end portion of the cylindrical container body for containing the contents so that the inner lid can be pushed down, and the nozzle is rotatable on the bottom wall. A discharge pipe having a top and bottom is provided, and a cover body that can be opened and closed is provided at the upper end of the container body that allows the contents to be dispensed by pressing the inner lid to protect the inner lid and the nozzle. Thus, a dispensing container configured to prevent the contents from being inadvertently pushed out has already been proposed as Japanese Utility Model Laid-Open No. 5-19172.

As shown in FIG. 4, the above-described device is an engagement support for erecting a discharge pipe 23 for pouring the contents on the bottom 21 a of a cylindrical container body 21 for containing highly viscous contents. A rod 21b is provided, and the upper end portion 21c of the cylindrical peripheral wall of the container main body has a holding plate 24 for projecting and holding the discharge pipe 23, and an insertion hole for inserting the discharge pipe. An inner lid 25 that is slidably fitted in close contact with the inner peripheral wall surface is provided, and is provided at the distal end portion of the discharge pipe 23 that protrudes horizontally above the holding plate 24 and is horizontally rotatable. A nozzle 26 is provided.
A lid body 22 having a top wall portion for accommodating the nozzle 26 is provided at the upper end portion of the container body 21 so as to be openable and closable via a rotary shaft 27, and the lid body is opened. The dispensing container 20 is configured such that the highly viscous contents are poured out from the opening of the tip of the nozzle 26 by pressing the inner lid 25.

In the above-described device, the highly viscous contents in the container main body 21 can be easily poured out from the nozzle 26 through the discharge pipe 23 by pushing down the inner lid 25, and the structure thereof is also compared with the conventional one. The nozzle 26 at the distal end of the discharge pipe is also protected by the lid body 22 and is convenient because it is not necessary to contaminate hands and instruments.
However, the above-described device is safe because the discharge nozzle 26 is protected. However, in order to hold the discharge pipe 23, an engagement support bar 21b is provided at the bottom, or a holding hole having a through hole 24a is provided. Since the plate 24 is provided and fixed, it is somewhat complicated, and there is no stopper to prevent the inner lid 25 that presses and discharges the contents from moving when not in use. There is still no room for improvement.

The invention of the present application can be easily dispensed without the use of a special special extraction tool or a complicated extraction pump to dispense the highly viscous contents contained in the hollow container. An object is to provide an inexpensive dispensing container that can be made.
Therefore, a pouring container containing a high-viscosity content so as to be able to be poured out, a cylindrical pouring container main body and a pouring piston having a pressing piston that slides in close contact with the main body of the pouring container. It comprises a piston, presses the pressing part of the dispensing piston and lowers the pushing piston so as to pressurize the contents in the container and dispense it from the dispensing nozzle, and when not in use The stopper is locked so that the pressing piston does not descend, and the contents are inadvertently poured out from the nozzle.
Then, the dispensing container has a very simple structure composed of parts with as few points as possible, and a safe dispensing container that can be manufactured at low cost without requiring any special dispensing means is provided.

The pouring container main body is a lid provided by standing a guide member for guiding the pressing piston at the bottom of the lower end of the cylindrical body, and screwing or fitting a lid on the upper end of the cylindrical body. An insertion port through which the discharge pipe is inserted is formed in the body so as to accommodate a highly viscous content inside.
Further, the pressing piston is formed so as to slide around the inner peripheral surface of the hollow container body by arranging a piston around the peripheral edge of the disk fitted to the dispensing container body. The connecting cylinder part which inserts the guide member of the said bottom part in a part is formed, and the discharge pipe which formed the extraction nozzle and the press part in the connection cylinder part of the said press piston was fitted, connected, and it can press and can press Is formed so that the high-viscosity contents housed in the dispensing container body can be pressed and poured out.

The dispensing container main body formed as described above contains a highly viscous content, and a pressing piston connected to the discharge pipe is slidably fitted into the dispensing container main body. The bottom guide member is inserted into the connecting tube portion so that the contents can be pressed.
At the upper end of the pouring container main body configured in this way, a lid is fitted and sealed in a state where the discharge pipe of the pouring piston is vertically movable, and the upper part of the lid of the discharge pipe A stopper is locked to the protruding portion to make it impossible to dispense the highly viscous contents of the dispensing container.

  The invention of the present application is a pressing portion of a dispensing piston in which a discharge pipe is connected to a pressing piston in which a highly viscous content housed in a wide-mouthed dispensing container body is slidably mounted in the dispensing container body. The contents are directly pressurized by the pressing piston and discharged from the dispensing nozzle at the tip of the discharge pipe, so that there is no need to use a special special removal tool, The contents can be easily taken out without being soiled.

  In addition, the present invention reduces the number of parts constituting the dispensing container as much as possible, so that the structure of the container becomes very simple and the assembly becomes very easy. The manufacturing cost can be reduced, and the stopper is locked to the discharge pipe of the dispensing piston so that the pressing piston cannot be lowered when not in use. There is nothing to do.

A rod-shaped guide member that guides and supports the pressing piston that presses the contents is erected on the bottom portion of the cylindrically formed lower end portion that is closed, and a lid is screwed or fitted to the upper end portion. A cylindrical container body is formed, and a cylindrical portion is inserted through the discharge pipe of the dispensing piston that dispenses the contents at the center of the lid so that the contents having high viscosity can be accommodated therein.

At the upper end of the pouring container body configured in this manner, the discharge pipe is passed through and a lid is fitted and sealed, and a stopper is locked to the discharge pipe protruding above the lid. Then, a protective lid is attached to the top of the lid so as to protect the dispensing nozzle at the tip of the discharge pipe, thereby constituting a dispensing container that accommodates the highly viscous content in a dischargeable manner.

  When the dispensing container 1 configured as described above is used, after removing the protective lid, the dispensing container 1 is placed on an appropriate flat surface and is placed on the upper end of the dispensing piston. When the formed pressing portion is pressed by a fingertip or the like, the discharge pipe descends and the content pressurized by the pressing piston is pushed up, so that the content passes through the gap between the guide member and the discharge pipe. The liquid is discharged from the tip opening of the dispensing nozzle 6.

The invention of the present application will be described in detail below with reference to the drawings based on an optimum embodiment.
In the present invention, as shown in FIG. 2, a thermoplastic synthetic resin is injection-molded to form a lid 7 on an upper end 2a formed into a cylindrical body, and the pressing piston 5 is guided to the lower end. Then, a bottom portion 2b provided with a supporting rod-shaped guide member 4 to be supported is provided, and a pouring container main body capable of accommodating a highly viscous content is formed.
On the other hand, a disc-like lid body 7 that can be fitted to the upper end of the dispensing container body 2 is molded by injection molding of a thermoplastic synthetic resin, and at the same time, poured into the central portion of the lid body. A fitting cylinder 7a is slidably inserted through the discharge pipe 6 of the piston 3 to form the dispensing container body 2 that can be sealed with the lid.

Similarly, a thermoplastic synthetic resin is injection-molded and formed into a disk 5c that can be fitted into the dispensing container body 2, and at the same time, the edge of the disk is in close contact with the inner surface of the dispensing container body 2. In addition to forming a slidable piston 5a, a pressing piston 5 having a connecting cylinder portion 5b for connecting a discharge pipe (stem) 6 for discharging contents to the center of a disc 5c is formed.
Further, a thermoplastic synthetic resin is injection-molded to form a tubular body, and a fitting portion 6a that can be fitted and connected to the connecting cylinder portion 5b of the pressing piston 5 is formed at the lower end of the tubular body. At the same time as forming the discharge nozzle 8 and forming the discharge pipe 6 provided with the pressing portion 6b, the guide member 4 is formed in the discharge pipe 6 so that the guide member 4 can be moved up and down. An engaging ditch 6c that can lock the stopper 9 is formed on the outer peripheral surface of 6.

Then, the discharge pipe 6 formed as described above is fitted and connected to the connecting cylinder portion 5b of the pressing piston 5 to form a discharge piston 3 that can be pressed and slid, and the connecting cylinder of the pressing piston 5 is formed. When the guide member 4 is inserted into the portion 5b and the piston 5a is brought into close contact with the inner peripheral surface of the dispensing container body 2 and is slidably fitted, the dispensing piston 3 capable of performing the dispensing operation is provided. Composed.
The guide member 4 provided with the pressing piston 5 on the bottom portion 2b of the discharge container main body is provided for the one having the highly viscous content stored in the cavity portion of the discharge container main body 2 configured as described above. After being inserted and slidably fitted into the dispensing container main body 2 (at this time, the lid is actually inserted through the discharge pipe), the upper end 2a of the dispensing container main body is covered with the lid. By inserting the body 7, as shown in FIG. 1, the dispensing container 1 that allows the contents to be poured out is formed.

For the pouring container 1 formed so as to be able to pour out the highly viscous content as described above, as shown in FIG. 3, it is roughly C-shaped shaped so as to be elastically deformable by injection molding of synthetic resin. The stopper 9 provided with the knob 9b on the locking portion 9a is press-fitted into the engaging recess groove 6c provided in the circumferential direction on the outer peripheral surface of the discharge pipe 6 to thereby form a C-shaped locking portion. It is made elastic so that the tip end portion of 9a is expanded, and engages as if the engaging portion is biting into the discharge pipe 6, and the flat lower surface 9c of the stopper 9 is closely attached to the upper surface of the lid body 7 and is engaged. And become immobile.
And in the pouring container 1 in which the contents cannot be discharged in this way, a cup-shaped protective lid 10 that protects the pouring piston 3 is covered from above the pouring nozzle 8, and the lid body By fitting and fixing the fitting portion 10a provided at the opening end of the protective lid 10 to the engaging portion 7b on the outer side, the dispensing container 1 as a product as shown in FIG.

In order to pour out and use the contents of the pour container 1 configured as described above, the protective lid 10 is removed from the pour container body 2 and the engagement groove 6c of the discharge pipe 6 is engaged. If the stopper 9 is removed, the dispensing piston 3 can be pressed and can be dispensed.
Therefore, after the pouring container 1 is placed on a suitable flat surface such as a table or a mirror or a table or a shelf, the opening / closing lid 8a that covers the opening of the discharge nozzle 8 is opened. When the pressing portion (pressing head) 6b of the dispensing piston is pressed with a fingertip or the like, the pressing piston 5 can be pushed down via the discharge pipe 6.

Subsequently, as shown in FIG. 2, when the pressing piston 5 is pushed down, the highly viscous content in the dispensing container is pressed by the pressing piston to be in a pressurized state.
In this way, the content that has been pressurized by the pressing piston 5 flows along the outflow groove 4a provided on the outer peripheral surface of the guide member 4, and the guide member 4 and the inner surface of the connecting cylinder portion 5b and It is pushed upward through a gap with the inner surface of the discharge pipe 6.
As a result, the contents are poured out from the opening of the tip of the pouring nozzle 8, so that the necessary amount can be received and used in an appropriate tray or palm.

The dispensing container 1 of the present invention dispenses if the discharge pipe 6 is pushed into the dispensing container main body 2 by pressing the pressing part 6b of the dispensing piston 3 to adjust the amount the pressing piston 5 descends. The content in the container 1 can be poured out as necessary.
Therefore, a plurality of the engaging concave grooves 6c provided on the outer peripheral surface of the discharge pipe 6 of the dispensing piston 5 are provided at positions serving as a guide for the amount of the contents to be dispensed, so that the stopper 9 can be locked. Therefore, if the pressing portion is pressed while viewing the engaging groove 6c, the engaging groove 6c serves as a scale, so that the required amount of contents can be obtained almost correctly and easily. Can be dispensed.

In the dispensing container 1 provided with a plurality of engaging grooves 6c as described above, the stopper 9 is locked in a locking groove 6c provided in the middle of the discharge pipe 6 of the dispensing piston 3. Thus, it is possible to make the lowering of the pressing piston immobile.
In this way, by locking the discharge pipe 6 in the middle of the container body and fixing the dispensing piston so that it cannot be lowered, the contents will not be dispensed when not in use, or in the case of use. It is also possible to prevent the contents in the container from being oxidized and denatured by oxygen in the air.

In the above-described embodiment, the dispensing container body 2 guides the pressing piston 5 that pushes out the contents in the dispensing piston 3 in the vertical direction and guides the flowing contents. 4 is formed in an integral structure so as to stand upright on the bottom wall portion 2b of the container body formed into a cylindrical shape, but the present invention is not limited to such a structure. It may be formed separately from the bottom wall portion and then joined later.
Further, the dispensing piston 3 is formed in a structure that can be pressed by connecting the separately formed pressing piston 5 to the discharge pipe 6 that is formed by providing the dispensing nozzle 8 and the pressing portion 6b. On the contrary, it is also possible to form the pressing piston 5 integrally with the discharge pipe 6 and to join the discharge nozzle 8 and the pressing portion 6b formed separately.
Furthermore, if the lid body 7 that seals the upper end portion of the dispensing container is formed in a structure that can be divided into two, the dispensing piston 3 can be easily attached to the container body.

As described above, although the dispensing container of the present invention has a very simple structure, a dedicated dispensing pump or a special dispensing tool is used like a conventional container containing high viscosity. Even without it, the contents can be easily taken out and the fingertips are not soiled.
Since the present invention reduces the number of parts constituting the dispensing container as much as possible and simplifies the structure of the container, it is extremely easy to assemble it. It can be manufactured at a lower cost than the dispensing container.
Also, by providing a stopper function to prevent the movement of the dispensing piston, even if the container body part is inadvertently applied with a pressing force for some reason, the pressing piston is prevented from descending. There is no danger of the contents being dispensed from time to time.

The dispensing container of the present invention configured as described above can easily dispense the highly viscous contents contained in the container without using a dedicated dispensing pump or special dispensing tool. Because it can be used, it can be used as a container for storing cosmetic products such as cosmetic creams, facial cleansing packs, hairdressing pomades, etc., or shampoos, rinses and other various hygiene products. .
In addition, containers containing various seasonings and foods such as mayonnaise, ketchup, white sauce, etc., as well as lubricating oil such as grease and leather protective materials such as shoe ink, or glue and other adhesives It can also be used as a container.
