The transparent cylinder 3 contains the fluid 2 in the through hole 3a. In this example, the fluid 2 is a cosmetic jelly and consists of a transparent component and a colored component. The colored component is
In the transparent component, two spirals having different diameters are formed. Therefore, the fluid 2 has the pattern 2a.

The pump means 4 is a rod-shaped body having a flange portion 4c at one end and a suction portion 4a at the other end. An opening for sucking the fluid 2 is formed at the tip of the suction portion 4a. The outer diameter of the rod-shaped body near the flange 4c is designed to be slightly smaller than the inner diameter of the through hole in the gasket 7. In this pump means 4, a cylindrical piston stem 4b projects from the flange portion 4c so that it can expand and contract.

The pump means 4 has a pump mechanism inside, and performs a pumping operation as the piston stem 4b expands and contracts. Specifically, in the pump means 4, when the piston stem 4b is compressed toward the flange portion 4c side, the contents stored in the pump means 4 are discharged from the end face opening of the piston stem 4b. When the hand is released from the compressed piston stem 4b, the piston stem 4b returns to its original position, and at the same time, the substance existing outside the pump means 4 is sucked into the pump means 4 through the opening in the suction portion 4a. .

The pump means 4 has a gasket 7 when the transparent cylinder 3 is erected with the neck portion 3b facing upward.

At the center of the inside of the discharge spout 9, a tubular body 9c having an inner diameter equal to the outer diameter of the piston stem 4b is formed. The tubular body 9c contacts the bottom surface of one end of the discharge spout 9 and communicates with one end of a discharge pipe 9b formed in a direction orthogonal to the central axis of the discharge spout 9. The opening 9a, which is the other end of the discharge pipe 9b, projects from the peripheral side surface of the discharge spout 9. The discharge spout 9 is connected to the pump means 4 in a state where the piston stem 4b is inserted into the tubular body 9c.

The collar member 15 is a substantially frustoconical member. The outer diameter of the larger bottom surface of the two bottom surfaces of the collar member 15 is formed to have the same size as the inner diameter of the neck portion 3 b of the transparent tubular body 3. On the peripheral side surface of the collar member 15, there is formed a through hole which is line-symmetric with respect to the central axis of the collar member 15 and which intersects with the central axis. Both ends of this through hole are suction openings 15a for sucking the fluid 2. At the center of the larger bottom surface of the collar member 15, a recess communicating with the through hole is formed. The shape of this recess is the same as the shape of the outer surface of the suction portion 4a of the pump means 4. In this embodiment, the collar member 15 is made of synthetic resin. The collar member 15 has a suction portion 4a in its concave portion.
Is attached to the pump means 4 in the inserted state. As a result, the neck portion 3b of the transparent cylindrical body 3 is sealed by the collar member 15, and the fluid 2 does not flow into the neck portion 3b. Further, in this embodiment, the suction direction of the fluid 2 by the suction portion 4a is changed by the collar member 15.
It is restricted in a direction orthogonal to the central axis of the transparent cylindrical body 3.

The floating bottom 5 is a thick disk-shaped member. The outer diameter of the floating bottom 5 is equal to the through hole 3a in the transparent cylindrical body 3.
It is the same size as the inner diameter of. The floating bottom 5 has a recess 5a formed in the center thereof. The internal shape of the recess 5 a is designed to be able to receive the suction portion 4 a of the fluid 2 in the pump means 4. Further, the end surface of the floating bottom 5 where the concave portion 5a is exposed is designed to be in contact with the inner peripheral surface of the transparent cylindrical body 3 where the step is formed. In this embodiment, the floating bottom 5 is made of synthetic resin. The floating bottom 5 is located on the end surface side of the through hole 3a of the transparent tubular body 3 on which the neck portion 3b is not formed, with the recess facing the neck portion 3b side, and through which the fluid 2 penetrates.
It is inserted in a liquid-tight manner in a.

The lower lid 10 is a substantially disk-shaped member having the same outer diameter as the outer diameter of the transparent cylindrical body 3. Transparent cylinder 3
In the above, the end face on the side where the floating bottom 5 is inserted is closed and connected to the transparent cylindrical body 3. The connection is made by engaging. A through hole is formed in the plate surface of the lower lid 10. In this embodiment, the lower lid 10 is made of synthetic resin. The lower lid 10 has a function of standing the pump type fluid dispensing container 1 in a stable state.

In this pump type fluid dispensing container 1, when the discharge spout 9 is pushed with a finger, the discharge spout 9 is accommodated in the second cylindrical body 8b of the upper lid 8, and the piston stem 4b of the pump means 4 is flanged 4c. Shrink to the side. When the finger is removed from the discharge spout 9, the discharge spout 9 and the piston stem 4b return to their original positions, and the fluid 2 is sucked into the pump means 4 through the opening of the suction portion 4a of the pump means 4. At this time, since the collar member 15 is attached to the suction portion 4a, the suction direction of the fluid 2 in the suction portion 4a is restricted to the direction orthogonal to the central axis of the transparent cylindrical body 3. As a result, only the central portion of the fluid 2 is not sucked. That is, the double spiral pattern 2a in the fluid 2
Only the inner spiral of these is not aspirated. Therefore, when the fluid 2 is sucked, the inner spiral and the outer spiral of the spiral pattern 2a are simultaneously sucked,
The pattern 2a does not collapse.

When the discharge spout 9 is pushed again with a finger, the discharge spout 9 is housed in the second cylindrical body 8b of the upper lid 8, and the piston stem 4b of the pump means 4 contracts toward the flange portion 4c. At the same time, a certain amount of the fluid 2 is discharged from the opening 9b of the discharge pipe 9b in the discharge spout 9. When the discharge spout 9 is released, the discharge spout 9 and the piston stem 4b return to their original positions, and the fluid 2 is sucked into the pump means 4 through the opening in the suction portion 4a of the pump means 4. Therefore, every time the discharge spout 9 is pressed with a finger, the fluid 2 is discharged from the opening 9a in the discharge spout 9 and sucked from the suction portion 4a.

As the fluid 2 is sucked and discharged, the amount of the fluid 2 contained in the through hole 3a of the transparent cylinder 3 decreases.
As the amount of the fluid 2 decreases, the floating bottom 5 becomes transparent.
In close contact with the suction portion 4a.
Further, when the suction / discharge of the fluid 2 by the pump means 4 is continued, the suction portion 4a of the fluid 2 in the pump means 4 is received in the recess 5a in the floating bottom 5. The end surface of the floating bottom 5 where the concave portion is exposed contacts the inner peripheral surface of the transparent cylindrical body 3 where the step is formed. At this time, the suction unit 4
Since the collar member 15 is attached to a, the fluid 2 does not enter the peripheral space of the pump means 4 other than the suction portion 4a. Therefore, the fluid 2 slightly exists in a slight space surrounded by the inner peripheral surface of the recess 5 a and the outer peripheral surface of the collar member 15 in the floating bottom 5. as a result,
The entire amount of the fluid 2 can be sucked and discharged by the pump means 4 without performing empty discharge (miss shot). In this pump type fluid dispensing container 1, since the fluid 2 is contained in a closed space in which air does not exist, the fluid 2
It does not lead to oxidation, decay, deterioration, etc.

According to this pump type fluid dispensing container 1, the entire amount of the fluid 2 is prevented from spoilage, oxidation, etc. without breaking the pattern 2a of the fluid 2 contained in the through hole 3a of the transparent cylindrical body 3. While sucking and discharging can be done. This pump type fluid dispensing container 1 has a simple structure and is easy to handle,
Since it is easy to manufacture, it can be mass-produced.

Further, the collar member 15 enables the pump type fluid dispensing container to suck the fluid contained therein without breaking its pattern. The collar member 15 has a simple shape, can be mass-produced, can be suitably used in the pump-type fluid dispensing container 1, and is very easily mounted.

(Modification) The pump-type fluid dispensing container of the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the object of the present invention.

The transparent cylinder is not particularly limited in its shape, size, structure, etc. as long as it can accommodate a fluid having a pattern formed in the through hole, and can be appropriately selected according to the purpose. . As in the above-mentioned embodiment, it may be the transparent cylinder body 3 having the neck portion 3b, or may be a straight tubular body body having no neck portion. If the neck portion is provided on the transparent cylinder, the outer diameters of the pump means and the collar member can be reduced. The transparent cylinder can be formed of a known transparent material such as glass and synthetic resin such as polycarbonate. In the case of a transparent cylinder made of glass, the reaction activity with the fluid contained therein is extremely low, and the fluid can be stably retained for a long period of time.

The fluid is appropriately selected depending on the intended purpose without any restriction, but examples thereof include cosmetic jelly, cream, lotion, food jelly, colored syrup, ketchup and mustard, and two-color toothpaste. Quasi-drugs and the like. The fluid may be composed of a single component or may be composed of two or more components. The fluid may contain a transparent component as long as a pattern is formed, or may be composed entirely of colored components. The pattern formed on the fluid is not particularly limited, and examples thereof include a spiral pattern, a lattice pattern, a mesh pattern, a dotted pattern, a pictorial pattern, a color-coded pattern, a blur pattern, and letters.

The pump means is not particularly limited in its shape, size and structure as long as it has a function of sucking and discharging a fluid, and a member having various known pump mechanisms per se. Can be used.
In the pump means 4 of the above-mentioned embodiment, the flange portion 4c is directly connected to the open end of the transparent cylinder body 3 so that the outer diameter of the rod-shaped body of the pump means 4 is the same as the inner diameter of the neck portion 3b of the transparent cylinder body 3. The opening of the suction portion 4a may be provided in the direction orthogonal to the central axis of the rod-shaped body of the pump means 4. In this case, it is not necessary to use the collar member and the gasket.

The upper lid, together with the gasket, has a function of preventing air from entering the transparent cylindrical body 3 and fixing the pump means to the transparent cylindrical body. The shape, structure, size, etc. of the upper lid are not particularly limited as long as they have the above-mentioned functions, and can be appropriately selected. If the pump-type fluid dispensing container is designed to have the above-mentioned function even without the upper lid, it is not necessary to provide the upper lid.

The discharge spout has a function of enabling the piston stem of the pump means to be operated by pushing with a finger and controlling the discharge direction of the fluid. The discharge spout is
As long as it has the above-mentioned function, its shape, size and structure are not particularly limited and can be appropriately selected.

The collar member can be provided in the suction portion of the pump means to prevent the fluid from entering the peripheral space other than the fluid suction portion of the pump means.
And as long as it has a function of being able to regulate the suction direction of the fluid by the pump means in the direction from the peripheral side surface of the transparent cylinder toward the central axis of the transparent container, there is no particular limitation, and its shape, size, The structure, material, etc. can be selected appropriately.

The number of suction openings in the collar member cannot be unconditionally specified because it depends on the size, shape, structure, etc. of the collar member, but it is preferably two or more.
The shape of the opening in the suction opening depends on the viscosity of the fluid, the composition,
It can be appropriately determined depending on the pattern formed on the fluid.

The floating bottom has a recess for receiving the fluid suction portion in the pump means, closes the through hole of the transparent cylinder so as to be slidable in close contact, and stores the fluid in a liquid-tight manner in the through hole of the transparent cylinder. There is no particular limitation as long as it has a function to do so, and the shape, size, etc. can be appropriately selected. Since the floating bottom rises against gravity as the fluid is sucked and discharged, it is preferable to design the structure and material so as not to receive as much gravity as possible. From this point of view, the hollow body structure and the floating bottom made of synthetic resin are preferable.

The lower lid has a function of stably erecting the pump type fluid dispensing container. As long as it has the above function, the lower lid is
It can be designed in various shapes, sizes, structures and materials. If the structure is such that it can be installed upright without the lower lid, the pump-type fluid dispensing container need not be provided with the lower lid. In this pump type fluid dispensing container, the center of gravity may move upward with use, and it may easily fall down.
It is preferable to form the lower lid with a heavy material. When the lower lid is made of a heavy material, the center of gravity is located at the lower side, so that the pump type fluid dispensing container is less likely to tip over.

Incidentally, the connection between the respective members can be selected by means such as adhesion by an adhesive, adhesion, screwing, fitting, and engagement according to the purpose.

Even in such a modification of the pump type fluid dispensing container, the same action and effect as the pump type fluid dispensing container 1 of the above-described embodiment can be obtained.
