Description

  The present invention relates to a container for volatile liquids.

  There has been proposed a liquid fragrance container configured to store a volatile liquid and to volatilize the volatile liquid by infiltrating the volatile paper installed in the upper part of the container body (see, for example, Patent Document 1). In addition, a liquid air freshener container has been proposed in which a volatile paper is installed on the upper part so that volatilization from the volatile paper is possible, and the liquid can be directly discharged to the outside by squeezing the container body ( For example, see Patent Document 2).

  In the former, a volatile paper is installed at the top of the container, and a stick-shaped volatile paper penetrating piece connected to the upper end of the volatile paper is suspended at the bottom of the container, and the liquid in the container is volatilized through the volatile paper penetrating piece. It is configured to permeate into the paper and volatilize the permeated liquid to the outside through the through hole of the cap attached to the container body.

  In the latter case, in addition to the volatile paper and the volatile paper penetrating piece having a similar configuration, the container body is configured to be squeezable, and the lower end of the pipe communicating with the small hole at the upper end of the container body is formed in the container body. It is made to hang down by the lower end part, and it is comprised so that volatilization liquid can be directly discharged outside by squeezing of a container trunk | drum.

  Each of the above liquid fragrance containers has the liquid infiltrated into the volatile paper through the volatile paper penetrating piece, so that the amount of liquid penetrating into the volatile paper tends to be a substantially constant impregnation amount at all times, In order to supply a sufficient amount of liquid to the upper volatile paper, the thickness of the volatile paper penetrating piece tends to be thick, and the amount of impregnation of the volatile paper tends to increase. Therefore, in this type of conventional container, volatilization with a relatively large volatilization amount per unit time is often performed. The desired amount of volatilization per unit time varies depending on the type or application of the volatilization liquid to be stored, but it is desirable that it can be changed as necessary.

  The present invention has been made in view of the above points, and can adjust the volatilization amount depending on the amount of foam discharged, can be adapted to various installation locations and uses, and the discharged foam is a volatilization chamber. It will not overflow or spill out from the liquid, and the liquid accumulated without being volatilized will not spill outside from the volatilization window, and excess liquid will be collected in the container body for efficient volatilization. We propose an excellent volatile liquid container that can be used.

The fifth means is configured as follows. That is, in any one of the second to fourth means, the radiation path p1 is extended to the position outside the discharge port 45.

  The container for volatile liquid of the present invention can recover excess liquid from the second dripping hole f2 of the volatilizing head D through the cap B and from the first dripping hole f1 of the cap B into the container main body A. Therefore, when the discharged bubbles cannot be volatilized, there is no inconvenience such as liquefaction and spilling to the outside through the volatilization window hole or the like, and the recovery into the container main body A can be performed efficiently. Further, there is an advantage that the volatile liquid in the container main body A can pass through the cap B from the first dropping hole f1 and can always be scented between the volatile head D and the cap cylinder wall part 20, and strongly scented. In the case where it is desired to operate, it can be dealt with by operating the foam generating device C to discharge the foam. Further, since the bubble-like volatile liquid is not jetted into the volatilization chamber R unless the foaming jetting device C is operated, there is an advantage that volatilization can be performed without waste when necessary as compared with the conventional product. Furthermore, by making the volatile liquid foam, the contact area with air is increased, and the volatile efficiency is greatly improved. In particular, since the volatilization window hole W1 is opened in the bottom wall portion 40 of the volatilization chamber R, this type of volatilized gas, which is generally heavier than air, is well dispersed in the atmosphere and further improves the volatilization efficiency.

  In addition, the amount of jetting by a single depressing operation of the volatilization head can be made relatively small, and a thin odor can be easily produced, for example, when a fragrance is stored as a volatile liquid. On the other hand, if the number of times the volatilization head is pushed down is increased as necessary, there is an advantage that the amount of impregnation can be increased stepwise.

Also, open the discharge port 45 in the cylindrical wall 42a of the discharge tube portion 42 projecting from the center of the bottom wall portion 40, the ejection cylinder portion 42 surrounding the annular passage p2 and annular passage p2 plurality of which is extended radially from A bubble channel p composed of the radiation path p1 is defined in the lower part of the volatilization chamber R by a protective wall 46 that prevents the invasion of bubbles, and a volatilization window hole W1 is formed in the bottom wall part 40 between the radiation paths p1. In this case, there is an advantage that the opening area of the volatilization window hole W1 can be increased, and bubbles discharged from the discharge port 45 can be evenly distributed in the flow path p.
This advantage is further ensured in the structure in which the bottom wall portion 40 is formed in a dome shape. In this configuration, the volatilization chamber R and the volatilization window hole W1 are provided between the protective walls 46 above the volatilization window hole W1. In the case where the communication wall 48 that communicates is opened at the peripheral portion and the covering wall 47 is provided across, the inconvenience that bubbles leak into the volatilization window hole W1 in the bottom wall portion can be prevented more reliably.

  The volatilization head D is divided into a base D1 having a peripheral wall 41 standing up from a peripheral edge of the bottom wall 40 provided with the discharge cylinder 42, the protective wall 46, and the cover wall 47, and an upper end of the peripheral wall 41 of the base D1. And a dome-shaped lid body D2 fitted with a lower end portion, and provided with a recessed portion 52 having a lower end opening in which the lower end portion of the lid body D2 is recessed inward. The lower end opening of the recessed portion 52 is formed at the top portion. When configured as the volatilization window hole W2, the volatilization gas not only volatilizes from below the bottom wall 40 via the volatilization head D and the cap cylinder wall 20 but also the volatilization window hole W2 at the top. The volatilization efficiency can be further improved since the volatilization can be performed uniformly above the volatilization head D, and the top volatilization window hole W2 is formed by the lower end opening of the recess 52, so The inconvenience such as the foam discharged to the top overflows from the top volatilization window hole W2. It can be prevented.

Alternatively, a through hole as a first dropping hole may be formed.

  As the foam generating device C, a device incorporating a known foam ejecting mechanism is used, and the lower end portion is suspended in the container body A and attached to the support cylinder 22, and the upper end is in an upward biased state. The stem 30 protrudes so that it can be pushed, and the liquid in the container main body A is bubbled by the vertical movement of the stem 30 and is jetted from the upper end of the stem 30 as a foam. A cylinder member 32 having an upper end fixed in the mounting cap 31 is suspended in the container main body A by screwing the peripheral wall of the cap 31. The cylinder member 32 includes a large-diameter air cylinder 32a at an upper position and a small-diameter liquid cylinder 32b provided continuously at a lower position. Further, a stem 30 having a reduced diameter at the upper end is erected from the center of the top of the mounting cap 31 so as to be able to be pushed in an upward biased state.

  In the cylinder member 32, a known mechanism is built in which the liquid in the container body A is bubbled and ejected from the upper end of the stem 30 as foam. If an example is demonstrated without showing in figure, the vertical motion member provided with the said stem 30 is accommodated so that a vertical motion is possible. The vertical movement member is connected to the lower end of the stem 30 with a small-diameter liquid piston slidably fitted to the inner periphery of the liquid cylinder 32b, and slidably fitted to the inner periphery of the air cylinder 32a.

Has a foam layer. The vertical movement member is always urged upward by a coil spring provided in the liquid cylinder. Further, a suction valve is provided at the lower end of the liquid cylinder, and an outside air introduction valve for introducing outside air is provided at the air piston.

  The volatilization head D includes a volatilization chamber R which is attached to the stem 30 and communicates the inside with the stem 30 and has a volatilization window hole W1. Further, in the upper end portion of the cylindrical wall portion 20 of the cap B, a volatilization gap is opened between the cylindrical wall portion 20 of the cap B and the outer periphery of the volatilization head D, and the lower end portion is accommodated so as to be movable up and down. . Further, the volatilization window hole W1 is formed in the bottom wall portion 40 of the volatilization head D so that this type of volatilized gas generally heavier than air can be efficiently discharged to the outside. Furthermore, although the volatilization head D is formed of a synthetic resin or the like, it can also be formed of a transparent or semi-transparent material so that the internal bubble ejection state can be seen from the outside.

  The volatilization head D in the illustrated example is composed of a base D1 and a lid D2. As shown in FIGS. 1 and 2, the base D <b> 1 is provided with a peripheral wall 41 that extends outward as it goes upward from the peripheral edge of the dome-shaped bottom wall 40. At the center of the bottom wall portion 40, a discharge cylinder portion 42 is projected, and the peripheral edge portion of the bottom wall portion 40 is formed in a recessed portion 43 where the bottom wall portion 40 is recessed in an annular shape. Further, a second dripping hole f <b> 2 is provided in the outer peripheral portion of the depressed portion 43. Furthermore, six locking ribs 44 project from the inner surface of the peripheral wall portion 41 at equal intervals in the circumferential direction.

  Further, the bottom wall portion 40 in the illustrated example has a dome shape with a discharge cylinder portion 42 projecting at the center, a bottom plate 40a having a peripheral portion recessed in an annular L shape, and a top surface of a depressed portion of the bottom plate 40a. And a plurality of connecting ribs 40b projecting radially outward at equal intervals in the circumferential direction, and the outer edge portions of the connecting ribs 40b are connected to the lower end portion of the inner surface of the peripheral wall portion 41, respectively. Therefore, the depressed portion 43 of the bottom wall portion 40 is constituted by the depressed portion of the bottom plate 40a and each connection rib 40b. And between each connection rib 40b outside the baseplate 40a is comprised as the 2nd dripping hole f2, respectively. In this case, it is also possible to adopt a form in which the depressed portion of the bottom plate 40a is extended to the peripheral wall portion and a through hole as the second dropping hole f2 is formed there.

  The discharge cylinder part 42 penetrates through the center of the bottom wall part 40, projects the bottom end of the cylinder wall 42a downward from the bottom wall part 40, the upper end of the cylinder wall 42a projects upward from the bottom wall part 40, and closes the upper end by the top plate 42b. Yes. Six discharge ports 45 are opened at equal intervals in the circumferential direction on the cylindrical wall 42a. In addition, six radiation paths p1 defined by a pair of protective walls 46 are formed between an outer position spaced from each ejection port 45 of the ejection cylinder portion 42 and immediately before the depressed portion 43, and each radiation is formed. The central sides of the adjacent protective walls 46 of the path p1 are integrally connected to each other to define an annular path p2 around the discharge cylinder portion 42, and the radial path p2 and each radiation extending radially from the annular path p2 A bubble channel p is formed with the channel p1.

  Further, volatilization window holes W1 are formed in the bottom wall portion 40 between the respective radiation paths p1. Each volatilization window hole W1 is a plan view substantially composed of two sides along the edge of the protective wall 46 on both sides, and an inner side spaced apart from the depression 43 and one side along the edge of the depression 43. It has a triangular shape. The base D1 is provided with a cover wall 47 that covers each of the volatilization window holes W1. Each covering wall 47 spans between the protective walls 46 above the volatilization window hole W1 by opening a communication hole 48 communicating with the volatilization chamber R and the volatilization window hole W1 at the periphery.

  The lid D2 is formed of a transparent synthetic resin, has a dome shape in which a curved top wall portion 51 continuous to the curved circumferential wall portion 50 is extended, and a lower end portion of the circumferential wall portion 51 is recessed inwardly. In the illustrated example, six recesses 52 are provided along the peripheral edge so that the tops of the six tops are recessed. The volatilization window hole W2 is opened. Then, the lower end edge of the peripheral edge portion is fitted and fixed to the upper end edge of the peripheral wall portion 41 of the base D1 to form the volatilization head D in which the volatilization chamber R composed of the bubble channel p and the space above it is defined.

  Further, as shown in FIGS. 1 and 2, the annular volatile body 60 is fitted into the recessed portion 43 at the periphery of the bottom wall portion 40, and the outer surface thereof is locked by the locking ribs 44. Volatile bodies can absorb volatile liquids and volatilize absorbed volatile liquids, and can be used in containers for ordinary volatile liquids, such as felt and volatile paper. Can be used. Felt is used as the volatilizing body 60 in this case. The upper end portion of the volatilizing body 60 protrudes slightly above the upper surface of the bottom wall portion 40. The volatilization head D as described above is attached by fitting the cylindrical wall 42a of the discharge cylindrical portion 42 to the outer peripheral upper end portion of the stem 30.

  When the volatile liquid container 1 configured as described above is used, when the volatilization head D is pushed down from the state shown in FIGS. 1 and 2, the stem 30 is lowered, and bubbles are volatilized through the discharge cylinder part 42. It spouts out to the bubble channel p in R. At this time, the bubbles are ejected laterally from the discharge port 45 on the side of the discharge cylinder portion 42, and further, since the cover wall 47 is provided, the bubble goes downward from the volatilization window hole W <b> 1 of the bottom wall portion 40. There is very little possibility of jetting, and since the top volatilization window hole W2 is open to the lower surface of the recessed part 52, there is very little possibility that bubbles overflow from the volatilization window hole W2 at the top. And the thing in which the bubble in the volatilization chamber R volatilized volatilizes outside from the volatilization window hole W2 of the top part, and from the volatilization window hole W1 of the bottom wall part 40 through the inside of the cylindrical wall part 20 of the cap B Volatilizes to the outside through the gap between the volatilization head D and the cylindrical wall portion 20. Further, a part of the foam is absorbed by the volatilizing body 60 through the radiation path p1, and further excess liquefied foam passes through the second dripping hole f2 and passes through the inside of the cylindrical wall portion 20 of the cap B, to the cap top. It is dropped and collected into the container main body A from the first dropping hole f1 of the wall portion 21.

  The bubble ejection will be described based on the above-described example. When the stem 30 is pushed down, the vertical movement member descends against the upward biasing force, and the liquid in the liquid cylinder rises in the stem and the air The air in the cylinder for use is pressurized and merges with the liquid in the stem through the air passage, and the foamed foam that has passed through the foaming layer is ejected from the upper end of the stem. If the pressing of the volatilization head D is released, the stem 30 is raised by the upward biasing force, and the volatilization head D is raised to return to the original state. At this time, outside air is introduced from the outside air introduction valve into the negative pressure cylinder 32a, and the liquid in the container body is introduced into the liquid cylinder 32b via the suction valve.
