BACKGROUND OF THE INVENTION
The present invention relates to a container with a pump of a type in which contents are simultaneously poured out from at least two chambers filled with contents having different compositions by a pump, and the contents are mixed immediately before use. It is intended to save resources by reusing parts.
[0002]
[Prior art]
In recent years, hair dyeing agents, facial cleansing foams, treatments, and the like that are used after mixing at least two types of liquid materials having different compositions immediately before use have been distributed as products. Such products are usually packed in separate containers for each liquid product, and they are usually sold as a set, and it is necessary to pour the liquid material from each container in use. There is a problem that it is not easy to use.
[0003]
As a container corresponding to such a product, one that uses a single pump to simultaneously pour out the contents from a plurality of containers by pumping operation of this pump has been proposed, As a prior art regarding this point, for example, an apparatus disclosed in JP-T-6-510013 is known.

[0015]
In the figure, reference numerals 1A and 1B denote content-containing chambers having threaded portions on the outer periphery of the opening. The chambers 1A and 1B maintain high sealing properties, and the bottom walls wa and wb are chambers 1A and 1B. It can be slid along the axis.
[0016]
2A and 2B are pumps suitable for dispensing high-viscosity liquids that suck up the contents in the contents storage chambers 1A and 1B and pour them out of the container. The pumps 2A and 2B suck the contents. It has a port Sc and a discharge port Dc, and includes piston head portions Pa and Pb urged to an initial position by a spring disposed in the casing of the pumps 2A and 2B.
[0017]
Reference numeral 3 denotes a base member that holds the pumps 2A and 2B by fitting or the like while leaving the suction ports Sc and the discharge ports Dc. The suction ports Sc of the contents of the pumps 2A and 2B held by the base member 3 The distal ends of the contents housing chambers 1A and 1B are screwed to the base member 3 so that the openings are located.
[0018]
Reference numeral 4 denotes a pumping member shown in the example in which the nozzle n is combined with two constituent members. The pumping member 4 is engaged with the piston heads Pa and Pb on the discharge side where the discharge ports Dc of the pumps 2A and 2B are present. For each pump 2A and 2B, the pressure of the piston heads Pa and Pb and The pumping operation accompanied by the release is simultaneously guided, and the contents passing through the discharge ports Dc of the respective pumps 2A and 2B are individually guided and discharged from the nozzle n to the outside of the container. The outer surface of each pump has a convex shape with the center protruding most so that the same pumping force can be applied to any pump, and the portion slips when pumping with a palm. A plurality of protrusions t are provided for preventing the above.
[0019]
Reference numeral 5 denotes a case member which is connected to the base member 3 and accommodates all of the content storage chambers 1A and 1B to form a container body. This case member 5 is a gas-liquid replacement penetration shown in the example provided on the bottom surface thereof. It has a hole 5a. Reference numeral 6 denotes an attachment / detachment mechanism. The detachable member 6 includes an opening 6a formed on the back surface of the case member 5 and an elastic tongue piece 6b that is integrally formed with the base member 3 and has a fitting protrusion that fits into the opening 6a. The case member 5 can be easily attached to and detached from the base member 3 by fitting and releasing the protrusion from the opening 6a.
[0020]
Reference numeral 7 denotes an elastic tongue piece which is shown as an example formed integrally with the bottom surface of the case member 5. The elastic tongue piece 7 is an elastic engagement between the case housing 5 and the content storage chambers 1A, 1B and the case member 5 in a state where the case member 5 is connected to the base member 3. It prevents rattling between them when it is mounted on the member 3.
[0021]
Reference numeral 8 denotes an overhang portion shown as an example formed integrally with the case member 5. The overhanging portion 8 prevents the container itself from overturning when the contents are poured out, that is, when the pumps 2A and 2B are pumped.
[0022]
As shown by the phantom line in FIG. 5, when the pumping member 4 is pressed and the pressure of the pumping member 4 is released with the piston head portions Pa and Pb positioned at the lowermost end in the pump casing, the pumping member 4 is positioned at the lowermost end in the pump casing. The piston head portions Pa and Pb thus moved so as to return to the initial position by the elastic force of the spring. At that time, the pistons Pa-1 and Pb-1 are also attached to the piston heads Pa and Pb so that the pistons Pa-1 and Pb-1 return to their initial positions, and therefore the cylinder chambers Pa-2 and Pb-2 are shifted to a negative pressure state. Accordingly, the check valves Pa-3 and Pb-3 are opened, and the contents in the chambers 1A and 1B flow into the cylinder chambers Pa-2 and Pb-2 of the respective pumps 2A and 2B through the suction port Sc.
[0023]
In the above process, outside air is sucked from the through hole 5a of the case member 5 and flows through the bottom openings k of the chambers 1A and 1B as shown in FIG. 6, and the bottom walls wa and wb of the chambers 1A and 1B are chambers. It slides toward the pumps 2A and 2B in accordance with the content of the contents in 1A and 1B.
[0024]
After the piston head portions Pa and Pb return to the initial positions together with the pistons Pa-1 and Pb-1, when the pumping member 4 is further pressed as shown in FIG. 7, the piston head portions Pa and Pb become the piston Pa-1, The cylinder chambers Pa-2 and Pb-2 and the passages provided in the pistons Pa-1 and Pb-1 communicate with each other when they move together with Pb-1 and reach a predetermined stroke. The contents in Pa-2 and Pb-2 are discharged from the discharge port Dc, and are individually discharged from the nozzle n to the outside of the container through the extraction paths 4A and 4B connected thereto. By repeatedly pressing and releasing the pumping member 4, the contents in the chambers 1A and 1B are continuously poured out.
[0025]
The container with a pump of the present invention has a structure in which the chambers 1A and 1B for storing the contents are screwed to the base member 3, so that the chambers 1A and 1B can be replaced after the contents are used up. The container main body including the pumps 2A and 2B can be used semipermanently and is extremely useful for resource saving of the material constituting the container.
In addition, a container having such a structure can be used by, for example, exchanging only the chamber in which the contents have been used up even if the contents in one chamber are used up and the contents remain in the other chamber. The remaining contents can be used without waste.
[0027]
The case member 5 forming the container body is provided with a through hole 5a so that even if water or the like enters from the outside, it can be discharged to the outside, and the bottom walls wa and wb slide smoothly during the pumping operation. However, a large number of openings 5b can be provided along with this. When such a through-hole 5a and an opening 5b are provided on the bottom surface of the case member 5, it is possible to quickly discharge the invading water and to facilitate the inflow of air.
In the configuration example of the container shown in FIGS. 1 to 4 above, a case where the central area of the bottom surface is concave is shown, but a gap may be formed between the bottom surface and the mounting surface on which the container is mounted. It is also possible to provide a plurality of projections 9 as shown in FIG. The through hole 5a and the opening 5b may be provided not only on the bottom surface of the case member 5 but also on a side wall portion including the bottom surface.
[0028]
FIG. 9 shows an external perspective view of a container with a pump according to the present invention, and FIG. 10 shows an external perspective view of the back surface of the container in a state where the pumping member 4 is removed and the attachment / detachment mechanism 6 is released.
[0029]
In FIG. 9, the dimension L is a space for securing the movable margin of the pumping member 4 when performing the pumping operation, and fits over at least half the circumference of this region. For example, a stopper 10 as shown in FIG. By doing so, it is possible to prevent the contents from being leaked by pressing against the meaning of the pumping member 4 at the time of shipping, transporting or not using the product.
[0030]
Further, with respect to the dimension L, a clearance is formed in a state where the pumping member 4 is pressed as much as possible by securing an operation allowance smaller than the dimension L, so that a hand or a finger may be sandwiched when the contents are poured out. No joy is lost.
[0031]
FIG. 12 shows an example in which the cap 11 is screwed to the opening of the chamber. By separately preparing a chamber containing the contents as a refill container, when the internal use in the chamber attached to the base member 3 is used up, the cap 11 is removed and the chamber is simply screwed into the base member 3. Quick replacement is possible.
Further, when the chambers 1A and 1B connected to the base member 3 are not used for a long period of time, in order to avoid quality deterioration of the contents, they are detached from the base member 3 and a cap 11 as shown in FIG. 11 is attached. By setting it, the quality of the contents can be maintained for a long time.
[0032]
The container according to the present invention can be constituted by using a material such as polyethylene terephthalate, and is excellent in chemical resistance, such as polyamide, polycarbonate, polyacetal, polybutylene terephthalate, or polyolefin-based materials such as polypropylene and polyethylene. It can also be composed of a thermoplastic resin or metal.
[0033]
As the molding method, an injection molding method or the like can be applied, but in particular, when the container is constituted by a thermoplastic resin such as polyethylene terephthalate, a biaxial stretch blow molding method or a direct blow molding method can also be applied.
[0034]
If the case member 5 and the content storage chamber are made of a translucent or transparent container, the remaining amount of the content can be easily confirmed from the outside of the container.
[0035]
【The invention's effect】
According to the present invention, since only the content storage chamber can be replaced, it is possible to effectively use resources by reusing the container body including the pump. Moreover, even if the contents remain in another chamber by appropriately replacing only the chamber in which the contents are used up, the contents can be used up without waste.
