Description

   Volatile container   

The present invention relates to a volatile container, and more specifically, to a volatile container having a structure in which a lid cannot be removed once it is locked for safety and hygiene during use.

Volatile containers are used to store fragrances, bactericides, pesticides, etc., and volatilize them over time. However, there are many cases in which the contents of the volatile containers are harmful to the human body. In the case of the volatile container with the contents as the object, it is undeniable that there is a concern that a young person or an elderly person accidentally removes the cover, which causes the leakage of the medicinal solution and the like and brings harm to the human body.

For example, there are commercially available volatile devices built into the room that use chlorine dioxide molecules to remove indoor viruses and bacteria to suppress the growth and development of molds, and to deodorize the malodor of domestic waste. This volatilization device is commercially available in a state that the liquid medicine is filled in the bottle and sealed, and when used, the sealing cap is removed, and the granules packed together are put into a chemical reaction with the liquid medicine, so that the generated The chlorine dioxide gas is volatilized in the room. After the granules are put in, they are replaced with a volatilization cap with a volatilization port.

In the case of the volatile container used above, no removal suppression measures were implemented for the replacement of the volatile cover after the chlorine dioxide gas was generated by the chemical reaction between the granules and the liquid agent. In such a case, there is a concern that the leakage of the medicinal solution and the like may cause harm to the human body by mistakenly removing the volatile cover.

Conventionally, various designs for making it difficult to remove the cover have been proposed in consideration of this situation (for example, Patent Literature 1, Patent Literature 2, and Patent Literature 3). however. In the case of these structures, although it is said that the cover is difficult to remove, it is only a level that can be removed by the strength of a child. Therefore, these structures cannot be used to effectively prevent the above-mentioned hazards.

As mentioned above, in the case of the conventional volatile container, the removal of the volatile cover is not fully implemented, so there is a danger that the volatile cover may be removed due to the removal of the volatile cover, which may cause harm to the human body, or the contents of the child will be harmed. Danger in the mouth.

Therefore, the object of the present invention is to provide a volatile container. Once the volatile cover is locked during use, it cannot be detached afterwards. Therefore, the volatile cover is not removed by mistake, which causes harm to the human body due to the content flowing out Concerns.

The first invention for solving the above-mentioned problem is characterized in that it is a volatile container provided with a volatile lid. The volatile lid includes an inner lid screwed to a bottleneck provided with a thread, and an outer cover covering the inner lid. A cover is provided with a volatile port communicating with the inner cover and the outer cover, and continuous or discontinuous protrusions are formed at the lower part of the inner peripheral surface of the inner cover. The continuous or discontinuous protrusions pass through the outer cover. Cover to lock the inner cover, thereby overcoming the detachment prevention flange provided at the lowermost part of the bottleneck, and then being caught by the detachment prevention flange, and formed at the lower part of the outer peripheral surface of the inner cover There are continuous or discontinuous protruding rings. The continuous or discontinuous protruding rings are slidably fitted in a ring groove formed on the lower part of the inner peripheral surface of the outer cover, and on the upper part of the outer peripheral surface of the inner cover. A ring-shaped segment portion with a stepped slope is formed, and a convex portion that slides along the slope of the ring-shaped segment is formed on the inner peripheral surface of the outer cover. The outer cover is formed by the ring-shaped portion. Level difference and the convex part is locked, thereby relative to The inner cover only acts in one direction of rotation to rotate the inner cover.

In one embodiment, the step is provided at four positions at 90-degree intervals or at two positions at 180-degree intervals, and the convex portions are provided at 90-degree intervals on the inner peripheral surface of the outer cover. Set at 4 locations or at 2 positions at 180-degree intervals. Moreover, in one embodiment, the protruding ring formed in the lower part of the outer peripheral surface of the inner cover is fitted into a ring groove formed in the lower part of the inner peripheral surface of the outer cover with a gap.

In one embodiment, the relative rotation of the inner cover and the outer cover can adjust the opening degree of the volatile port of the inner cover and the volatile port of the outer cover.

The volatile container of the present invention has the above-mentioned structure. Therefore, if the volatile cover is locked when in use, the protrusion of the inner cover goes beyond the bottleneck prevention flange and is caught by the prevention flange. Unable to remove the volatile cover. Therefore, there is an effect that there is no concern that the content flow out may cause harm to the human body by removing the volatile cover by mistake, and it is suitable as a volatile container.

The volatile container of the present invention will be described in accordance with the accompanying drawings. FIG. 1 is an exploded perspective view of an embodiment of the volatile container of the present invention. As described herein, the volatile container includes a bottle 1 and a volatile cap screwed onto the bottleneck 2 of the bottle 1. The volatilization cover is a double-layer cover composed of an inner cover 11 and an outer cover 21 that is installed and mounted on the inner cover 11. Generally, the inner cover 11 and the outer cover 21 are made of resin such as polypropylene. However, in order to suppress deformation when the cover is held, it is preferably a grade having excellent rigidity. In addition, in order to reduce friction between the inner cover 11 and the outer cover 21 and make the sliding between the two covers good, it is preferable to use a surface coating type or a kneading type antistatic agent.

A screw thread 3 for screwing the inner cap 11 is formed on the bottle neck 2 of the bottle 1, and a ring-shaped anti-detachment flange 4 is formed on the lower side of the screw thread 3.

The upper surface of the inner cover 11 has a dome shape, etc., and a plurality of volatile ports 12 of appropriate size are formed here. The volatile ports 12 correspond to the volatile ports 22 and the volatile ports 12 and 22 openings of the outer cover 21 described later. The degree can be adjusted by the relative rotation operation of the inner cover 11 and the outer cover 21. The shape and arrangement of the volatile ports 12 and 22 are arbitrary, and are not limited to those in which the long holes are arranged in a radial shape as shown in FIG. 1, and may have various shapes and arrangements as illustrated in FIG. 6.

A ring-shaped section 13 is provided on a peripheral edge of the upper surface of the inner cover 11 with a step 14 provided at a plurality of locations. The step system 14 is arranged at four positions at 90-degree intervals on the peripheral edge of the upper surface of the inner cover 11 or at two positions at 180-degree intervals, of course, other intervals may also be used. Each step 14 is an inclined surface (refer to FIGS. 2 and 3). However, in order to reduce frictional resistance when rotating counterclockwise as much as possible, it is preferably an inclined surface that is as smooth as possible. Further, a continuous or discontinuous ring-shaped protruding ring 15 is formed on the lower part of the outer peripheral surface of the inner cover 11, and a thread 16 corresponding to the thread 3 of the bottleneck 2 is formed on the inner peripheral surface, and is formed on the lower side thereof. There are continuous or discontinuous protrusions 17. In the example shown in FIG. 2, the protrusion 17 is divided into four parts.

The upper surface of the outer cover 21 is formed in a dome shape or the like corresponding to the upper surface of the inner cover 11, and a plurality of volatilization ports 22 are formed as described above. On the upper part of the inner peripheral surface of the outer cover 21, convex portions 23 (see Figs. 2 and 3) that slide along the slope of the annular segment portion 13 are formed at 90 positions at 4 positions or at 180 positions at 2 positions. . For example, the convex portions 23 are arranged at an interval from 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 cover 11 is fitted is formed at the lower portion of the inner peripheral surface of the outer cover 21, and an annular seat portion 25 (see FIG. 2) defining the ring groove 24 is formed on the lower side thereof. 3). The protruding ring 15 is fitted into the ring groove 24 with a certain gap. The inner diameter of the annular seat portion 25 is designed to be slightly smaller than the outer diameter of the protruding ring 15.

The volatile container of the present invention is, for example, a bottle 1, a volatile cap, and granules that are put into the bottle 1 during use and are packaged together for sale. The bottle 1 is filled with a liquid medicine and is sealed with a seal. The cover is covered with a temporary cover which is then discarded. The volatile cover includes an inner cover 11 and an outer cover 21. In addition, the temporary cover is removed and the sealing strip is peeled off during use, and the granules are put into the bottle 1 to cause a chemical reaction with the liquid medicine. After that, the volatile cover of the inner cover 11 and the outer cover 21 is screwed together to volatilize the gas generated by the chemical reaction through the volatilization ports 12 and 22.

When the volatile cover including the inner cover 11 and the outer cover 21 is screwed together, first, the outer cover 21 is covered and pressed into the inner cover 11, so that the protruding ring 15 is forcibly slid into the ring groove 24. . This operation is made possible by the outer cover 21 having a certain degree of elasticity. Furthermore, since the protruding ring 15 is accommodated in the ring groove 24 and is locked there, the outer cover 21 cannot be removed from the inner cover 11.

In such a state that the outer cover 21 is covered with the inner cover 11, the convex portion 23 disposed on the inner peripheral surface of the outer cover 21 is abutted against the inclined surface of the annular section portion 13 of the inner cover 11. In addition, since the protruding ring 15 is not tightly accommodated in the ring groove 24 but has a plurality of gaps, the outer cover 21 is rotatable relative to the inner cover 11.

However, in the case where the convex portion 23 of the outer cover 21 is rotated to slide along the descending slope of the annular section portion 13 (usually clockwise), when it abuts on the step 14, it will prevent further rotation. . On the other hand, in the case of turning in the reverse direction (usually counterclockwise), the convex portion 23 slides along the rising slope of the annular segment portion 13, so that the step 14 can be crossed. That is, the outer cover 21 can rotate (idle) in its direction.

In the state where the outer cap 21 is capped on the inner cap 11 as described above, when the inner cap 11 is screwed onto the neck 2 of the bottle 1, the screwing can be achieved by rotating the outer cap 21. That is, if the outer cover 21 is rotated in the clockwise direction, that is, the screwing direction, when the convex portion 23 abuts on the step 14, the rotational force is directly transmitted to the inner cover 11. Moreover, if the outer cover 21 is rotated in the screwing direction, the inner cover 11 is rotated integrally. First, the protrusion 17 is screwed to the thread 3 of the bottleneck 2 to spirally advance, and then the thread 16 is screwed to the thread 3 to spirally advance.

Eventually, the ridge 17 reaches the abutment against the detachment prevention flange 4 to generate resistance. However, if the ridge 17 directly rotates with a strong force, the ridge 17 passes over the detachment prevention flange 4. The projecting of the protrusion 17 over the anti-detachment flange 4 is not achieved by simply pressing in, but is achieved by a screw forward force, so it can be easily performed with a relatively small force. When the ridges 17 pass over the detachment prevention flange 4 in this way, the ridges 17 are firmly caught on the detachment prevention flange 4 without falling off.

As such, in the case of the volatile container of the present invention, the volatile cover is replaced with two layers inside and outside when in use. Once locked, the volatile cover cannot be removed afterwards, so the volatile cover can be accidentally removed and the content will flow out The occurrence of the state of affairs can continue to use the volatile container safely and hygienicly for a long time, so that its industrial availability is great.
