Description

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

The volatilization container is for storing fragrances, fungicides, pesticides, etc. and volatilizing them over time, but the contents stored in the volatilization container are often harmful to the human body. .. In the case of a volatilization container for such contents, it is undeniable that young people and the elderly may accidentally remove the lid and spill chemicals, etc., which may cause harm to the human body.

For example, an indoor type volatilizer that removes viruses and bacteria in a room by using chlorine dioxide molecules, suppresses the growth of mold, and deodorizes bad odors such as swill is commercially available. This volatilizer is commercially available in a sealed state in which a liquid drug is filled in a bottle. When using this device, the sealing lid is removed, and the included granules are added to chemically react with the liquid drug to generate the gas. The chlorine dioxide gas is volatilized indoors, and it is a type that is replaced with a volatilization cap that has a volatilization port included in the package after the granules are added.

In the case of the volatilization container used above, the replacement volatilization cap to be adhered after the granule and the liquid chemical are chemically reacted to generate chlorine dioxide gas is not provided with measures to suppress removal. In the case of such a volatilization container, the volatilization cap may be accidentally removed and chemicals or the like may spill out, causing harm to the human body.

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

As mentioned above, in the case of the conventional volatilization container, since the measures to suppress the removal of the volatilization cap are not sufficiently taken, the volatilization cap is accidentally removed and the chemical solution etc. spills out, causing harm to the human body or infants. There was a danger of eating the contents.

Therefore, the present invention provides a volatilization container in which once the volatilization cap is tightened at the time of use, it cannot be reliably removed thereafter, so that the volatilization cap is accidentally removed and the contents flow out, so that there is no risk of harm to the human body. The task is to do.

The invention according to claim 1 for solving the above problems is a volatilization container provided with a volatilization cap including an inner cap screwed to a screwed bottleneck and an outer cap covered with the inner cap. hand,
The inner cap and the outer cap are provided with a volatilization port that communicates with each other, and the inner cap is tightened at the lower part of the inner peripheral surface of the inner cap via the outer cap to the lowermost part of the bottleneck. A series of or discontinuous ridges are formed that overcome the retaining flange provided and then are locked by the retaining flange.
A series of or discontinuous protrusions that are slidably fitted in the ring groove formed in the lower part of the inner peripheral surface of the outer cap are formed in the lower part of the outer peripheral surface of the inner cap.
Further, an annular step portion of a slope having a step is formed on the upper portion of the outer peripheral surface of the inner cap, and a convex portion sliding along the slope of the annular step portion is formed on the inner peripheral surface of the outer cap. The outer cap is characterized in that the convex portion is locked by the step of the annular step portion, so that the outer cap acts on the inner cap only in one rotation direction to rotate the inner cap. It is a container.

In one embodiment, the steps are provided at four locations at 90 degree intervals on the annular step portion or at two locations at 180 degree intervals, and the convex portions are provided at 90 degree intervals on the inner peripheral surface of the outer cap. It is provided at 4 locations or at 2 locations at 180 degree intervals. Further, in one embodiment, the protruding ring formed in the lower part of the outer peripheral surface of the inner cap is fitted with play in the ring groove formed in the lower part of the inner peripheral surface of the outer cap.

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

Since the volatilization container according to the present invention has the above configuration, once the volatilization cap is tightened during use, the ridges of the inner cap get over the retaining flange of the bottleneck and are locked by the retaining flange, and thus volatilize thereafter. It will not be possible to remove the cap reliably. Therefore, there is an effect that there is no possibility that the volatilization cap is accidentally removed and the contents flow out, causing harm to the human body, which makes it suitable as a volatilization container.

It is a top view which shows various shape examples of the volatilization port of the inner cap and the 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 accompanying 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 is composed of a bottle 1 and a volatilization cap screwed to a 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 engaged with and mounted on the inner cap 11. Normally, the inner cap 11 and the outer cap 21 are made of a resin such as polypropylene, but in order to suppress deformation when the cap is gripped, a grade having excellent rigidity is preferable. Further, 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 slip between the caps.

A screw thread 3 for screwing the inner cap 11 is formed on the bottleneck 2 of the bottle 1, and an annular retaining flange 4 is formed on the lower side of the screw thread 3.

The upper surface of the inner cap 11 is formed into a dome shape or the like, and a large number of volatilization ports 12 of appropriate sizes are bored therein. The volatilization port 12 corresponds to the volatilization port 22 of the outer cap 21 described later, and the degree of opening 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 shapes and arrangements of the volatilization ports 12 and 22 are arbitrary, and are not limited to those in which the elongated holes as shown in FIG. 1 are arranged radially, and a wide variety of shapes and arrangements as exemplified in FIG. 6 are possible. be.

An annular step portion 13 having steps 14 at a plurality of positions is formed on the upper peripheral edge of the inner cap 11. The steps 14 are, for example, arranged at four places at 90 degree intervals on the upper peripheral edge of the inner cap 11 or at two places at 180 degree intervals, but it goes without saying that other intervals may be used. .. Although the slopes are formed between the steps 14 (see FIGS. 2 and 3), it is preferable to make the slopes as gentle as possible in order to reduce the frictional resistance when rotated counterclockwise as much as possible. Further, a series of or discontinuous annular protrusions 15 are formed on the lower portion of the outer peripheral surface of the inner cap 11, and a screw thread 16 corresponding to the thread 3 of the bottleneck 2 is formed on the inner peripheral surface thereof. At the same time, a series of or discontinuous ridges 17 are formed on the lower side thereof. In the example shown in FIG. 2, the ridge 17 is divided into four parts.

The upper surface of the outer cap 21 has a dome shape 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 sliding along the slope of the annular step portion 13 are formed at four locations at 90-degree intervals or two locations at 180-degree intervals (FIGS. 2 and 2). 3). For example, the convex portions 23 are arranged every other position at the position where the volatilization port 22 is formed (see FIGS. 2 and 3). Further, a ring groove 24 into which the protruding ring 15 of the inner cap 11 is fitted is formed in the lower portion of the inner peripheral surface of the outer cap 21, and an annular receiving portion 25 defining the ring groove 24 is formed below the ring groove 24. See Figures 2 and 3). The ridge 15 is fitted in the ring groove 24 with some 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 includes, for example, a bottle 1 filled with a liquid chemical, a hermetically sealed seal, and a temporary lid to be discarded later, 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 put on the market. Then, at the time of use, the temporary lid is removed, the sealing seal is peeled off, and the granules are put into the bottle 1 to cause a chemical reaction with the liquid drug. After that, 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 to forcibly slide the protruding ring 15 into the ring groove 24. This operation is possible because the outer cap 21 has a certain degree of elasticity. Thus, the protruding ring 15 fits in the ring groove 24 and is locked there, so that the outer cap 21 cannot be removed from the inner cap 11.

In the state where the outer cap 21 is attached to the inner cap 11 in this way, the convex portion 23 disposed on the inner peripheral surface of the outer cap 21 comes into contact with the slope of the annular step portion 13 of the inner cap 11. Since the protruding ring 15 is not tightly housed in the ring groove 24 and has some play, the outer cap 21 can rotate 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 the outer cap 21 hits the step 14. Will be done. On the other hand, when it is rotated in the opposite direction (usually counterclockwise), the convex portion 23 slides along the ascending slope of the annular step portion 13, so that the step 14 can be exceeded. That is, the outer cap 21 can rotate (idle) in that direction.

With the outer cap 21 attached to the inner cap 11 as described above, the inner cap 11 is screwed to the bottleneck 2 of the bottle 1, and the screwing is achieved by turning the outer cap 21. To. That is, when the outer cap 21 is rotated in the screwing direction, which is usually a clockwise direction, the convex portion 23 hits the step 14, and the turning power 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, and the ridge 17 is first screwed into the screw thread 3 of the bottleneck 2 and screwed, and then the screw thread 16 is screwed. Is screwed into the screw thread 3 and is screwed.

Eventually, 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 overcoming of the retaining flange 4 of the ridge 17 is not a mere pushing but a screwing force, so that it can be easily performed with a relatively small force. When the ridge 17 gets over the retaining flange 4 in this way, the ridge 17 is firmly locked to the retaining flange 4 and cannot be pulled out.

As described above, in the case of the volatilization container according to the present invention, once the volatilization cap is replaced with the inner and outer double volatilization caps and tightened once, the volatilization cap cannot be removed thereafter, so that the volatilization cap is carelessly removed and the contents flow out. The occurrence of such a situation is avoided, and the volatilization container can be used safely and hygienically for a long period of time, and its industrial applicability is great.
