Description

The present invention relates to a liquid container with a small extraction port. In particular, the present invention relates to a container that is used by shaking and mixing and then opening the lid.

Before use, a liquid container containing a layered liquid or a container containing a liquid and a powder is shaken to mix. After that, when the lid is opened, liquid may suddenly spurt out. Such a phenomenon is called pump-up. In the pump-up, the liquid content clogged in the vicinity of the extraction port is pushed out at the time of opening the lid with the shaking operation, and the pressure inside the container is increased at the time of mixing, so that the liquid is ejected. This is because the air pressure inside the container may rise due to body temperature or the like. In particular, a viscous container for liquid cosmetics has a small extraction port and a small amount is taken out for use, so that cosmetics tend to accumulate in the extraction port. Various skin care bases, liquid foundations, hair styling products, etc. have been developed and are on the market, but some of them use multiple types of liquids with different specific gravities or a mixture of liquids and powders. Such cosmetics and the like contain the above-mentioned plurality of types of liquids in one container, and when the container is held in a stationary state, they are separated into multiple upper and lower layers due to the difference in specific gravity. The mixture is sufficiently stirred. As the container is moved and the cosmetics and the like are stirred evenly, the liquid content accumulates in the narrow extraction port. The pressure inside the container may rise through the rise in room temperature or body temperature, in which case the accumulated liquid may spurt out at the same time as opening the cap.
In order to avoid pumping up, Patent Document 1 (Japanese Unexamined Patent Publication No. 2002-193296) and Patent Document 2 (Japanese Patent Laid-Open No. 07-31647) have been proposed.
Patent Document 1 includes a bottomed tubular container body for accommodating a foundation, a cap to be attached to the neck of the container body, and an extraction nozzle is provided at the neck opening of the container body. , A container for a liquid for mixing is disclosed, which is configured to cover the lower end opening of the liquid passage formed in the extraction nozzle with a non-woven fabric.
According to Patent Document 2, in a liquid container containing a mixing ball, a liquid container is provided with tapers on the lower left and right sides of the extraction nozzle so that the nozzle is not blocked by the ball even when the container is inverted. Is disclosed.
It has been found that these conventional means cannot prevent the liquid component remaining in the extraction nozzle from being ejected, and further studies have been made to realize the present invention.

(3) The liquid container according to (1) or (2), wherein the nozzle C has an opening at the tip of the nozzle head and has a distribution hole having a diameter smaller than the opening diameter.
(4) The nozzle C has a main body and a nozzle head having an outer diameter smaller than that of the main body, and has a convex annular portion on the outer peripheral surface of the main body that is in close contact with the inner cylinder of the nozzle cap. The liquid container according to any one of (1) to (3).

(8) The liquid container according to any one of (1) to (7) is a multi-liquid layer or a liquid container for filling cosmetics containing powder and liquid.

(1) A liquid container that can prevent leakage when the lid is opened has been realized. In particular, even in a liquid container that is shaken before use to mix the contents and then opened, a liquid container that prevents leakage such as unexpected pop-out that occurs when the lid is opened can be realized.
(2) Since the lid is provided with a boss for inserting into the extraction port to open and seal the sealing film, the extraction port of the nozzle cap needs to have a size that allows the boss to be inserted. In order to prevent leakage when the lid is opened, it was examined to narrow the distribution channel and increase the outflow resistance of the internal solution. However, in order to secure the insertion of the boss, it is difficult to make the distribution hole narrow because there is a limit.
Therefore, by forming the nozzle cap and the nozzle separately, the diameter of the flow hole in the nozzle can be reduced and the outflow resistance can be increased. Furthermore, the extraction head of the nozzle cap has the strength to stabilize the adhesion by inserting the boss when not in use. Therefore, by inserting the tip side of the nozzle into the extraction head, the support and fixing of the nozzle is stable. Even if it was shaken, the risk of falling off could be reduced. By separating the nozzles, the nozzles can be formed longer than the nozzles integrally formed with the nozzle cap, and the flow holes can be made longer as well as smaller in diameter to control the flow resistance. Since the flow hole has a small diameter, even if it leaks, the amount is small.
(3) The separate nozzle is stable because it is fixed by the tip side inserted into the extraction head of the nozzle cap and the main body portion having a convex annular portion that abuts and adheres to the inner cylinder portion of the nozzle cap. Is supported. Further, the sealing property between the nozzle and the nozzle cap is also improved.
(4) When the container is shaken and mixed, surface tension may cause a liquid pool to form on the neck of the bottle, and the liquid may spurt out when the lid is opened. However, the liquid pool on the neck is a curved part on the neck of the bottle. Since it can be formed above (curvature start point), it is possible to prevent the liquid accumulated in the neck of the bottle from being blown out by setting the lower end of the nozzle to a position below it.
Also, the lower end of the nozzle need not be below the shoulder of the bottle. If there is a space above the container and the lower end of the nozzle is in that space, even if the internal pressure of the bottle rises when the lid is opened, the nozzle will suck in air, so the liquid accumulated in the neck will not blow out. Absent.
(5) By providing the nozzle separately from the nozzle cap with an extraction port, it is possible to form a tapered flow hole with a small diameter even when the nozzle is molded by a molding die. In molding means such as injection molding, when forming an elongated tunnel-shaped flow hole, it is difficult to remove the mold unless a taper is attached. Therefore, when molding the nozzle integrally with the nozzle cap, the extraction port has a small diameter portion. As a result, a taper is formed so that the lower end side is widened, a flow hole having a diameter smaller than the hole diameter into which the boss is inserted cannot be formed, and the amount of liquid remaining in the flow hole cannot be reduced. Since the distribution resistance is small, the amount of leakage when the lid is opened cannot be reduced.
(6) The nozzle has the same outer shape as the top and bottom so that both ends can be attached, and the assembly work can be easily performed without trouble. Even if large openings into which a boss can be inserted are provided on the tip side of the nozzle at the top and bottom, the flow hole connecting the top and bottom openings can have a small diameter. Even with a tapered flow hole, the widening side can be made smaller than the opening diameter.
(7) An unopened sealing seal is provided at the extraction port, and a ring indicating unopened and maintaining the unopened container is placed at the lower end of the lid in the container to be opened by inserting a boss at the time of opening.
(8) Provided is a container containing a ball for promoting stirring and mixing of the contained contents. When the container is shaken and stirred and mixed, the pressure inside the container rises due to body temperature and the like, which causes the contents to be pushed out when the lid is opened. The present invention has been devised to increase the flow resistance in the nozzle and prevent the nozzle from sucking in excess liquid.
(9) The liquid container of the present invention is suitable for a cosmetic container.

The present invention is a liquid container provided with a bottle A, a nozzle cap B attached to the bottle neck, a nozzle C provided on the bottle neck, and a lid D, and the nozzle cap B is fitted to the neck of the container. It has a double wall of a cylinder and an outer cylinder, and an extraction head having an extraction port sealed with a sealing film at the tip, and the lid D has a boss that can be inserted into the extraction port to open the seal. The nozzle C is a liquid container provided with a nozzle head and a flow hole to be inserted into the extraction head of the nozzle cap. (Note that "bottle A", "nozzle cap B", "nozzle C", "lid D", "ring E", and "mixing ball F" are the "bottle 5" attached to the following specifications and drawings. , "Nozzle cap 3", "Nozzle 4", "Cap 1", "Ring 2", "Ball 6".)
In the present invention, the nozzle cap and the nozzle are separated, and the nozzle structure is separated from the nozzle cap structure and restrictions on molding. For example, when molding a nozzle integrally with a nozzle cap having an extraction port that requires an opening diameter large enough for a boss to perforate a sealing film provided at the extraction port at the start of use, demolding is performed. Considering this, the diameter of the flow hole in the nozzle is tapered so that the open side of the lower end expands, which is larger than the diameter of the extraction port on the tip side. As a result, since there are restrictions on the thickness of the boss such as strength, it is not possible to freely design the inner diameter of the nozzle, and it is difficult to reduce the amount of liquid accumulated in the nozzle in a mixed type liquid container.
According to the present invention, the inner diameter of the nozzle is made smaller than the diameter of the extraction port by separating the nozzle, and the resistance force of the liquid accumulated in the nozzle is increased to exert the function of the plug. Further, even when the container internal pressure becomes high, the amount of liquid remaining in the nozzle is reduced, so that the pump-up amount is also reduced.
Furthermore, by separating the nozzles, the outer shape and length of the nozzles can be freely set, and the nozzle mounting structure and the amount of voids in the bottle neck can be adjusted.

An example of the liquid container of the present invention is shown. FIG. 1A is an overall view (partially fracture surface), and FIG. 1B is a bottom view of the lid (bottom view of the cap). FIG. 2 shows a container with the cap 1 removed.
The liquid container includes a bottle 5 and a cap 1, and a ring 2 is fitted on the lower end side of the cap 1 when not in use. A nozzle cap 3 is attached to the neck of the bottle 5, and a nozzle 4 connected to an extraction port of the nozzle cap extends into the neck of the bottle 5. A boss 12 for opening is provided in the center of the inside of the cap 1.

The cross section of the head of the liquid container is shown in FIG.
The nozzle cap 3 is screwed to the outer periphery of the neck portion 51 of the bottle 5, and the cap 1 is screwed to the outer peripheral surface of the nozzle cap 3. The nozzle 4 is connected to an extraction port 32 provided in the extraction head 31 of the nozzle cap 3. Further, the ring 2 is arranged between the lower end of the outer cylinder 13 of the cap 1 and the shoulder 52 of the bottle 5 to limit the lowering of the cap 1 and prevent the boss 12 from piercing the sealing film 42. And it shows the virgin state. It is schematically shown that the stirring ball 6 is in the bottle.
The nozzle cap 3 has a tubular shape with an open bottom and an extraction port 32 having an extraction port 32 sealed with a sealing film 42 on the tip side, and has an outer cylinder 33 and an inner cylinder extending from the extraction head 31. It has a double-tube structure having 34. The nozzle cap 3 is fitted to the bottle neck 51 between the inner cylinder 34 and the outer cylinder 33. The inner cylinder 34 is in close contact with the inner wall of the bottle neck 51, and the outer cylinder 33 and the outer circumference of the neck 51 are screwed together.

The nozzle 4 has a tubular shape with a flow hole 41 provided in the center, and has a narrow outer diameter on the tip side so that it can be mounted in the space inside the extraction head 31. In the illustrated example, the outer diameters on both ends have the same shape and are used for both upper and lower sides. The main body of the nozzle 4 is in close contact with the inner wall of the inner cylinder 34 of the nozzle cap 3. In the illustrated example, a bulging portion (convex annular portion) is provided in the main body portion of the nozzle 4 in order to improve the adhesion. In the illustrated example, the lower end of the nozzle 4 is set to a length located below the widening start point from the bottle neck 51 to the shoulder 52. Further, it is desirable that the lower end of the nozzle 4 is not below the shoulder portion 52. As will be described in detail later, when the lower end of the nozzle 4 is extended below the shoulder, the remaining amount that cannot be extracted increases even if the nozzle 4 is inverted when the remaining amount is low, and the impact due to the collision with the ball 6 increases. Will increase, causing adverse effects such as dropping out.
In the illustrated example, the nozzle is provided so that the widening start point from the neck to the shoulder of the container body is the line of L1, the shoulder is the line of L3, and the line L2 at the lower end of the nozzle is between L1 and L3. It is preferable to set the length of.

The relationship between the widening start point and the lower end of the nozzle is to prevent the nozzle from sucking the residual amount at the time of pumping up when the liquid remains in the gap between the neck and the nozzle. In the process of examining the phenomenon of pump-up, the present inventor noticed that a liquid amount larger than the empty amount in the nozzle may flow out, and the cause was that there was a liquid content remaining in the bottle neck. It was clarified that the nozzle sucked it and the outflow amount increased. As a measure to prevent the suction, as a result of examining the position of the lower end of the nozzle, it was found that the liquid level remaining on the neck becomes a place where the inner diameter of the neck starts to increase due to surface tension, etc., and is below the liquid level. It was found that the suction of the residual liquid in the neck can be prevented by placing the lower end of the nozzle in.

The nozzle 4 has a tubular shape, and a tunnel-shaped flow hole having an inner diameter d4 is provided at the center thereof. The inner diameter d4 is set smaller than the diameter d1 of the extraction port 32. When molding an elongated tunnel, it is necessary to use a tapered elongated needle-like material, and when molding the nozzle integrally with the extraction head, the inner diameter d4 of the nozzle is the diameter of the extraction port when the extraction port is sealed. It cannot be smaller than d1.
In this example, the nozzle head 43 is mounted in the inner space of the nozzle cap extraction head 31, the outer shape of the nozzle body is in close contact with the inner cylinder of the nozzle cap and is stable, and the outer shape of the nozzle body and the bottle neck are stable. The gap between the inner wall surfaces of the nozzle cap 3 is the thickness of the inner cylinder 34 of the nozzle cap 3. It was stated that the liquid may remain on the bottle neck and that it can be prevented by devising the length of the nozzle, but it is difficult to prevent the liquid from remaining and it may become a liquid that cannot be taken out. There is sex. The present invention can reduce the unusable residue to this void amount. In this example, both ends have the same shape, but by making the lower end side of the nozzle body an outer diameter close to the inner diameter d2 of the bottle neck 51 without making the shape the same, this residue can be further reduced as much as possible.

The cap 1 includes an outer cylinder 13, an inner cylinder 14, and a top plate 11, and has a boss 12 at the center on the inner surface side of the top plate 11, and a convex ring portion 15 is formed around the boss 12. The inner cylinder 14 is formed with a female screw that is screwed with the outer cylinder 33 of the nozzle cap 3.
The boss 12 has a function of entering the extraction port 32 of the nozzle cap 3, piercing and opening the sealing film 42, and closely contacting the extraction port. The convex ring portion 15 is formed in a shape that is in close contact with the outer surface of the extraction head 31 of the nozzle cap 3. The convex ring portion 15, the boss 12, the top surface of the convex ring portion, and the outer shape and mouth of the extraction head 31 of the nozzle cap 3 form a tightly closed state, and the liquid is violently shaken in a mixing operation or the like. Is configured to prevent leakage.
Further, the lower end of the outer cylinder 13 of the cap 1 abuts on the ring 2 in the unopened state, and the lowering is restricted so that the boss 12 does not break through the sealing film 42, ensuring the virgin state of the liquid container. doing.

The main part of the liquid container in the state after opening is shown in FIG.
At the time of opening, the cap 1 is once removed, the ring 2 is removed, and the cap 1 is tightened again, so that the boss 12 pierces the sealing film 42 and opens. The closed state at the time of use is shown in FIG. Although it is shown so that there is a gap between the convex ring portion 15 and the extraction head 31, it is a gap in the drawing and is actually set to be in close contact with the convex ring portion 15.

An example of the nozzle 4 is shown in FIG.
The nozzle 4 has an elongated pipe shape in which a flow hole 41 having openings 46 at the top and bottom is formed in the center thereof, and a nozzle head 43 having a small diameter is provided at least on the upper side of the main body 48. ..
The nozzle head 43 is provided with an opening 46a at the tip and a convex annular portion 44 at the middle. A convex annular portion 45 is provided in the middle portion of the main body portion 48. An opening 46b is provided at the lower end, and a gate 47 is formed at least on the lower end side by cutting out a part of the peripheral wall.
In the illustrated example, the outer shape of the nozzle is formed in the same manner as above and below, and when the nozzle cap 3 is inserted into the inner space of the extraction head 31, it is molded so that the assembly and mounting work can be performed without any confusion. ing.

The flow hole 41 of the nozzle 4 is a tapered tunnel using a needle-shaped member in a molding means for injection molding using a molding mold. In the illustrated example, a taper is formed in which the upper end side has a small diameter and the lower end side has a large diameter. A widened opening 46 is formed at the tip of the flow hole 41. The widened opening 46 has substantially the same size as the hole diameter of the extraction port 32 of the nozzle cap 3, and is large enough for the boss 12 to enter.
The gate 47 is formed as a notch so that the liquid can be taken into the flow hole 41 and poured out even when the opening 46b on the lower end side is closed by the ball 6.

For example, the flow hole 41 has a small diameter portion of about 1 mm and an opening diameter of about 2 mm, and when the length of the bottle neck portion 51 and the length of the extraction head 31 of the nozzle cap 3 are taken into consideration, the nozzle The length is 20 mm or more. The cross section of the flow hole is 1/4 of the opening, and the resistance of the liquid increases due to the addition of the length factor. This distribution resistance is large enough to withstand the increase in internal pressure caused by temperature changes in the environment in which the cosmetics in the container are used. Even if the internal pressure becomes high due to exposure to an unexpected high temperature, the volume of the flow hole is small, so that the discharge amount can be reduced. For example, in this example, the discharge amount is 1/4 of that of a nozzle having a flow hole having the same diameter as the opening 46.

The tip of the nozzle 4 is inserted into the inner space of the extraction head 31 of the nozzle cap 3, and the convex annular portion 44 formed on the nozzle head 43 is pressed against the inner wall of the extraction head of the nozzle cap 3 to be in close contact with the nozzle cap 3. The convex annular portion 45 formed on the main body portion 48 is pressed against the inner cylinder portion 34 of the nozzle cap 3 and comes into close contact with the inner cylinder portion 34. The nozzle head is inserted and held, and the two convex annular portions firmly maintain the fixation with the nozzle cap. Then, leakage from between the nozzle and the nozzle cap is prevented.
Further, the main body may be provided with an annular portion having a size that contacts the inner diameter of the bottle neck 51 to reduce the amount of liquid staying in the air inside the bottle neck and reduce the amount of unusable liquid.
In the illustrated example, as described above, the outer shape of the nozzle is formed vertically symmetrically to prevent deterioration of mounting workability, but the head of the upper end is made thinner and the lower end side is the main body. It can be formed with the same thickness or slightly thicker to make the distinction between the upper and lower parts clear.

An example of the nozzle cap 3 is shown in FIG.
The nozzle cap 3 is attached to the bottle neck portion 51, has an inner space to which the nozzle is mounted, and has an extraction port 32 at the tip portion. Further, a locking mechanism for preventing the nozzle cap attached to the bottle from being reversed and coming off is composed of a base end portion of the bottle neck portion and a base end portion 38 of the nozzle cap 3. As the locking mechanism itself, the structure used in other examples can be used.
The nozzle cap 3 has a extraction head 31 at the top, a male screw on the outer peripheral surface extending downward from the extraction head 31, an outer cylinder 33 having a female screw formed on the inner peripheral surface, and the outer peripheral surface in close contact with the inner wall surface of the bottle neck. The inner peripheral surface has an inner cylinder 34 that is in close contact with the outer peripheral surface of the main body 48 of the nozzle 4. The lower end of the outer cylinder needs to have a length that forms a detent mechanism, and in the illustrated example, it is formed so as to cover the bottle neck 51 and reach the bottle shoulder 52. The inner cylinder 34 does not need to be long, but secures adhesion stability and a length required for holding the nozzle.

The inner diameter of the nozzle cap 3 is gradually reduced in several stages from the inner diameter of the outer cylinder 33 to the hole diameter of the extraction port 32. The inner diameter of the inner cylinder 34 is the size that the nozzle main body 48 is in close contact with, the extraction head 31 has the extraction hole 35 and the extraction port 32, and the extraction head inner space 35 is the size that the nozzle head 43 is in close contact with. That's right. The extraction inner space 35 is formed so that the convex annular portion 45 of the nozzle 4 can enter the lower side thereof, and the upper portion thereof is formed in the extraction inner space upper portion 35a having a slightly reduced diameter.
The nozzle body 48 is in close contact with the inner cylinder inner space 36 of the inner cylinder 34, and the lower end side of the inner cylinder inner space 36 is pressed against the convex annular portion 45 of the nozzle body 48 to be in close contact. The inner space 37 of the outer cylinder 33 is in close contact with the neck portion 51 of the bottle 5.
The tip side of the extraction port 32 is sealed with a sealing film 42, and the pore diameter of the extraction port 32 is formed so that the boss 12 can enter. The extraction port 32 is continuous with the flow hole 41 of the nozzle, but as described above, since the nozzle 4 is a separate body, the hole diameter of the flow hole 41 can be freely designed.

The ring 2 exists between the lower end of the cap 1 and the shoulder portion 52 of the bottle 5, and is a function of preventing the cap 1 from lowering. At the same time, the presence of the ring 2 also indicates that it is in an unused state, which makes the product distinction clear. Further, in the illustrated example, a step portion is formed so that the upper portion of the ring is in close contact with the inner surface of the outer cylinder 13 of the cap 1, and the cap 1 is designed to rotate together and come off when the cap 1 is opened. .. In particular, when the outer shape of the bottle is deformed to be an ellipse or the like, the outer shape of the cap 1 and the shape of the ring are also elliptical, and the bottle can be easily rotated by the action of a lever at the time of opening.

The nozzle 4 is intubated into the nozzle cap 3, and the cap 1 having the ring 2 fitted at the lower end is screwed onto the nozzle cap 3 to prepare the assembled cap body.
In the liquid container of the present invention, a cap body assembled after filling a bottle 5 with a first liquid and another second liquid or powder is attached.

When the cap 1 is removed at the start of use, the ring 2 also rotates together and comes off from the liquid container. When the ring 2 is separated from the cap 1 and the cap 1 is reattached, the boss 12 cuts open the sealing film 42 and extracts it. The mouth 32 will be opened. In that state, shake the liquid container to mix, open the lid, and extract and use the internal solution.

As a means for suppressing the pump-up phenomenon, the present inventor has studied a one-part member that integrally molds the nozzle from the opening of the nozzle cap, but the opening diameter is increased so that the liquid does not stay in the nozzle. It was not possible to do so, and in particular, the higher the viscosity, the more difficult it was to prevent retention. On the other hand, reducing the nozzle diameter has a limit that it cannot be made smaller than the outer shape of the boss with one part member in relation to the boss. Further, as described above, it was found that the amount of liquid leaked by pumping up was related to the volume of the void in the bottle neck, and it was also found that it was difficult to form a nozzle having a long diameter with a small diameter with one part. ..
According to the present invention, the nozzle is made into two parts separate from the nozzle cap to avoid these restrictions and to be freely designed, which is particularly suitable for a mixed type liquid container. .. By separating the nozzles, it is possible to form a flow hole having a small diameter regardless of the hole diameter of the extraction port, and the length can be freely set. We found that it is preferable to set the nozzle length below the widening start point of the bottle neck and above the shoulder line, increase the in-pipe resistance due to the length, and reduce the amount of liquid remaining in the neck. It is possible to reduce the amount of unusable liquid.
