Description

Volatilization container

The present invention relates to a volatilization container, and more particularly to a volatilization container having a structure in which the cap cannot be removed after being temporarily tightened for safety, hygiene, and the like.

Volatilization containers are used to store fragrances, bactericides, insecticides, etc., and volatilize them over time, but the contents stored in the volatilization containers are often harmful to the human body. . In the case of such a volatilization container for the contents, it cannot be denied that a young person or an elderly person may accidentally remove the lid and spill chemicals or the like, causing harm to the human body.

For example, an indoor type volatilization apparatus that removes viruses and bacteria in the room using chlorine dioxide molecules, suppresses the growth of mold, and deodorizes bad odors such as garbage is commercially available. This volatilization device is marketed with a liquid medicine filled in a bottle and sealed, and when used, the sealing lid is removed and the enclosed granules are added to cause chemical reaction with the liquid medicine. The chlorine dioxide gas is volatilized indoors, and is replaced with a volatilization cap having a volatilization port included after the granules are charged.

In the case of the volatilization container used above, the replacement volatilization cap that is deposited after the chemical reaction between the granule and the liquid chemical to generate chlorine dioxide gas is not provided with a measure to prevent removal. In the case of such a volatilization container, there is a risk that the volatilization cap is removed by mistake, and chemicals or the like spill out, causing harm to the human body.

Conventionally, in consideration of such a case, various devices for making it difficult to remove the lid have been proposed (for example, Patent Document 1, Patent Document 2, and Patent Document 3). However, in these configurations, even if it is difficult to remove the lid, it is only at a level that can be removed even with the power of a child, so it is not possible to effectively prevent the occurrence of the above-mentioned harm with these configurations. .

As mentioned above, in the case of conventional volatilization containers, the volatilization cap removal prevention measures are not sufficiently taken, so the volatilization cap is removed accidentally and chemicals etc. spill out, causing harm to the human body, There was a danger of consuming the contents.

Therefore, the present invention provides a volatilization container that does not pose a risk of harm to the human body because the volatilization cap is accidentally removed and the contents are leaked because once the volatilization cap is tightened during use, it can no longer be reliably removed. The task is to do.

The invention described in claim 1 for solving the above problem is a volatilization container provided with a volatilization cap comprising an inner cap screwed to a screwed bottleneck and an outer cap mounted on the inner cap. And
The inner cap and the outer cap each have a volatilization opening that communicates with each other, and the inner cap is tightened to the lowermost portion of the bottleneck by tightening the inner cap via the outer cap. A series or discontinuous ridges are formed, overcoming the provided retaining flange and then locked by the retaining flange,
A series of or discontinuous protrusions that are slidably fitted in an annular groove formed in the lower part of the inner peripheral surface of the outer cap are formed at the lower part of the outer peripheral surface of the inner cap,
In addition, an annular stepped portion having a step is formed on the outer peripheral surface of the inner cap, and a convex portion that slides along the inclined surface of the annular step portion is formed on the inner peripheral surface of the outer cap. The outer cap has a volatilization characterized in that the convex portion is locked by the step of the annular step portion so that the inner cap is rotated by acting only on the inner cap in one rotation direction. It is a container.

In one embodiment, the step is provided in the annular step portion at four positions at intervals of 90 degrees or at two positions at intervals of 180 degrees, and the convex portions are spaced at intervals of 90 degrees on the inner peripheral surface of the outer cap. It is provided at four places or at two places at intervals of 180 degrees. In one embodiment, the protrusion formed on the lower portion of the outer peripheral surface of the inner cap is fitted with play in the annular groove formed on the lower portion of the inner peripheral surface of the outer cap.

In one embodiment, the degree of opening of the volatilization port of the inner cap and the volatilization port of the outer cap can be adjusted by relative rotation of the inner cap and the outer cap.

Since the volatilization container according to the present invention has the above-described configuration, once the volatilization cap is tightened during use, the protrusion of the inner cap gets over the retaining flange of the bottle neck and is locked by the retaining flange. The cap cannot be removed reliably. Therefore, there is an effect that the volatilization cap is accidentally removed and the content flows out, and there is no risk of harm to the human body, which makes it suitable as a volatilization container.

It is a top view which shows the example of various shapes of the volatilization opening | mouth of the inner cap and outer cap of the volatilization container which concerns on this invention.

The volatilization container according to the present invention will be described with reference to the attached drawings. FIG. 1 is an exploded perspective view of an embodiment of a volatilization container according to the present invention. As described therein, the volatilization container includes a bottle 1 and a volatilization cap that is screwed to the bottleneck 2 of the bottle 1. It consists of. The volatilization cap is a double cap composed of an inner cap 11 and an outer cap 21 that is engaged and mounted on the inner cap 11. Usually, the inner cap 11 and the outer cap 21 are made of resin such as polypropylene, but in order to suppress deformation when the cap is gripped, a grade having excellent rigidity is preferable. Preferably, a surface coating type or kneading type antistatic agent is used in order to reduce the friction between the inner cap 11 and the outer cap 21 and improve the sliding between the caps.

The screw neck 3 for screwing the inner cap 11 is formed on the bottle neck 2 of the bottle 1, and an annular retaining flange 4 is formed below the screw thread 3.

The upper surface of the inner cap 11 is formed in a dome shape or the like, and a large number of volatilization ports 12 having appropriate sizes are formed there. The volatilization port 12 corresponds to a volatilization port 22 of the outer cap 21 described later, and the opening degree of the volatilization ports 12 and 22 can be adjusted by a relative rotation operation of the inner cap 11 and the outer cap 21. The shape and arrangement of the volatilization ports 12 and 22 are arbitrary, and are not limited to those in which long holes as shown in FIG. 1 are arranged in a radial manner, and various shapes and arrangements as illustrated in FIG. 6 are possible. is there.

An annular step portion 13 provided with steps 14 at a plurality of locations is formed on the periphery of the upper surface of the inner cap 11. For example, the step 14 is arranged at four positions at intervals of 90 degrees on the peripheral edge of the upper surface of the inner cap 11 or at two positions at intervals of 180 degrees, but it goes without saying that other intervals may be used. . The gap between the steps 14 is inclined (see FIGS. 2 and 3), but it is preferable to make the slope as gentle as possible in order to reduce the frictional resistance when rotating counterclockwise as much as possible. In addition, a series or discontinuous annular protrusion 15 is formed at the lower part of the outer peripheral surface of the inner cap 11, and further, a screw thread 16 corresponding to the screw thread 3 of the bottle neck 2 is formed on the inner peripheral surface thereof. At the same time, a series or discontinuous protrusion 17 is formed on the lower side. In the example shown in FIG. 2, the protrusion 17 is divided into four.

The upper surface of the outer cap 21 is formed in a dome shape or the like corresponding to the upper surface of the inner cap 11, and a large number of volatilization ports 22 are formed as described above. On the upper part of the inner peripheral surface of the outer cap 21, convex portions 23 that slide along the slope of the annular step portion 13 are formed at four locations at 90 ° intervals or at two locations at 180 ° intervals (FIG. 2, FIG. 2). 3). For example, the convex part 23 is arrange | positioned every other at the volatilization port 22 formation position (refer FIG.2, 3). Further, an annular groove 24 into which the protruding ring 15 of the inner cap 11 is fitted is formed at the lower part of the inner peripheral surface of the outer cap 21, and an annular receiving portion 25 that defines the annular groove 24 is formed below the annular groove 24 ( (See FIGS. 2 and 3). The projecting ring 15 is fitted into the annular groove 24 with a certain amount of play. Further, the inner diameter of the annular receiving portion 25 is designed to be slightly smaller than the outer diameter of the protruding ring 15.

The volatilization container according to the present invention is, for example, a bottle 1 that is filled with a liquid medicine and a hermetic seal is affixed, and a temporary lid to be discarded later is attached, a volatilization cap composed of an inner cap 11 and an outer cap 21, The granules to be put into the bottle 1 at the time of use are bundled and offered for sale. Then, the temporary lid is removed at the time of use, and the hermetic seal is peeled off. The granules are put into the bottle 1 to cause a chemical reaction with the liquid medicine. Thereafter, the volatilization caps of the inner cap 11 and the outer cap 21 are screwed, and the gas generated by the chemical reaction is volatilized through the volatilization ports 12 and 22.

When screwing the volatilization cap composed of the inner cap 11 and the outer cap 21, first, the outer cap 21 is put on the inner cap 11 and pushed in, thereby forcibly sliding the projecting ring 15 into the annular groove 24. This operation is possible because the outer cap 21 has a certain degree of elasticity. Thus, since the projecting ring 15 is accommodated in the annular groove 24 and is locked there, the outer cap 21 cannot be removed from the inner cap 11. *

Thus, in a state where the outer cap 21 is attached to the inner cap 11, the convex portion 23 disposed on the inner peripheral surface of the outer cap 21 comes into contact with the inclined surface of the annular step portion 13 of the inner cap 11. The projecting ring 15 is not tightly accommodated in the annular groove 24 and there is some play, so that the outer cap 21 is rotatable with respect to the inner cap 11.

However, when the convex portion 23 of the outer cap 21 is rotated so as to slide along the downward slope of the annular step portion 13 (usually clockwise), further rotation is prevented when it hits the step 14. Is done. On the other hand, when it is rotated in the opposite direction (usually counterclockwise), the convex portion 23 slides along the upward slope of the annular step portion 13, so that the step 14 can be exceeded. That is, the outer cap 21 can be rotated (idle) in that direction.

While the outer cap 21 is attached to the inner cap 11 as described above, the inner cap 11 is screwed to the bottle neck 2 of the bottle 1. The screwing is achieved by turning the outer cap 21. The That is, when the outer cap 21 is rotated in the screwing direction, which is typically clockwise, the convex portion 23 hits the step 14, so that the rotational force is transmitted to the inner cap 11 as it is. Thus, when the outer cap 21 is rotated in the screwing direction, the inner cap 11 is rotated integrally. First, the protrusion 17 is screwed into the screw thread 3 of the bottle neck 2 and then screwed, and then the screw thread 16. Screwed into the thread 3 and advanced.

Soon, the ridge 17 comes into contact with the retaining flange 4, and resistance is generated. However, if the ridge 17 is strongly rotated as it is, the ridge 17 gets over the retaining flange 4. The overhanging of the protrusion 17 on the retaining flange 4 is not a simple push-in operation but a screw advance force, and can be easily performed with a relatively small force. When the ridge 17 gets over the retaining flange 4 in this manner, the ridge 17 is then firmly locked to the retaining flange 4 and cannot be removed.

In this way, in the case of the volatilization container according to the present invention, when using the volatilization cap, it is impossible to remove the volatilization cap after it is replaced with the inner and outer double volatilization caps and tightened at one end. Therefore, the volatilization container can be used safely and hygienically for a long time, and its industrial applicability is great.
