Description

Volatilization container

Technical Field

The present invention relates to a volatilization vessel, and more particularly, to a volatilization vessel having a structure in which a cap cannot be removed once fastened for safety, hygiene, and the like in use.

Background

The volatilization vessel is a vessel for containing a fragrance, a bactericide, an insecticide, or the like, which takes time to volatilize them, but the contents contained in the aforementioned volatilization vessel are harmful to the human body in many cases. In the case of a volatilization vessel targeting such contents, it cannot be denied that young or elderly people may accidentally remove the lid, spill a medicinal liquid, etc., and cause harm to the human body.

For example, a volatile device of an indoor type is marketed, which removes viruses and bacteria in a room by using chlorine dioxide molecules, suppresses growth of mold, and deodorizes an odor of garbage or the like. The volatilization device is sold in the market in a state that a liquid medicine is filled in a bottle and sealed, and is a device as follows: when in use, the sealing cover is detached, the granules in the same package are put into the sealing cover to be chemically reacted with the liquid medicament, and the generated chlorine dioxide gas is volatilized indoors.

In the case of the volatilization vessel used in the above, no removal suppression measure is taken with respect to the refill volatilization cap that is covered after the chlorine dioxide gas is generated by chemically reacting the granules with the liquid chemical. In such a volatilization vessel, the volatilization cap may be removed by mistake, and the chemical liquid or the like may be spilled to cause damage to the human body.

In view of such circumstances, various designs have been proposed to make it difficult to detach the cover (for example, patent document 1, patent document 2, and patent document 3). However, in the case of these structures, even if the cap is difficult to detach, the cap is at a level that can be detached with the force of a child, and therefore, the occurrence of the above-described damage cannot be effectively prevented with these structures.

Patent document 1: japanese patent laid-open publication No. 2002-173186.

Patent document 2: japanese patent laid-open No. 11-262518.

Patent document 3: japanese patent No. 5389533.

As described above, in the case of the conventional volatilization container, since the removal prevention measure of the volatilization cap is not sufficiently performed, there is a risk that the volatilization cap is detached by mistake and the chemical solution or the like is spilled to cause a hazard to the human body or the contents are put into the mouth by an infant.

Disclosure of Invention

Therefore, an object of the present invention is to provide a volatilization container in which a volatilization cap is fastened once at the time of use and then is not surely detached any more, so that there is no possibility that the volatilization cap is detached by mistake and the contents flow out to cause harm to the human body.

The invention described in claim 1 for solving the above problems is a volatilization container comprising a volatilization cap composed of an inner cap and an outer cap, wherein the inner cap is screwed to a bottle neck provided with a screw thread, and the outer cap is covered and mounted on the inner cap, and the volatilization container is characterized in that volatilization ports which are respectively communicated with each other are formed in the inner cap and the outer cap; a series of or discontinuous protruding strips are formed at the lower part of the inner peripheral surface of the inner cap, the protruding strips are screwed down by the outer cap to cross the anti-loosening flange, and then are locked by the anti-loosening flange, and the anti-loosening flange is arranged at the lowest part of the bottle neck; a series of discontinuous protruding rings are formed at the lower part of the outer peripheral surface of the inner cap, the protruding rings are slidably embedded into the ring grooves, and the ring grooves are formed at the lower part of the inner peripheral surface of the outer cap; further, an annular step portion having a step-like slope is formed on an upper portion of an outer peripheral surface of the inner cap, and a protrusion portion sliding along the slope of the annular step portion is formed on an inner peripheral surface of the outer cap, and the outer cap is locked by the step-like step portion by the protrusion portion, and rotates the inner cap by acting only in one rotational direction with respect to the inner cap.

In one embodiment, the step is provided at 4 at 90-degree intervals or at 2 at 180-degree intervals on the annular step portion; the projections are provided at 4 at 90-degree intervals or at 2 at 180-degree intervals on the inner peripheral surface of the outer cap. In one embodiment, a projecting ring formed on a lower portion of an outer peripheral surface of the inner cap is fitted into a ring groove formed on a lower portion of an inner peripheral surface of the outer cap with play.

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.

The volatilization vessel according to the present invention is configured as described above, and therefore, when the volatilization cap is fastened in use, the protrusion of the inner cap goes over the release preventing flange of the bottle neck and is locked by the release preventing flange, and therefore, the volatilization cap cannot be removed reliably thereafter. Therefore, there are the following effects: the volatilization cap is not removed by mistake, and the contents are not discharged, which may cause harm to human body, and is suitable for use as a volatilization container.

Detailed Description

The volatilization vessel pertaining to the present invention will be explained with reference to the accompanying drawings. Fig. 1 is an exploded perspective view of an embodiment of a volatilization vessel according to the present invention, which is composed of a bottle 1 and a volatilization cap screwed onto a neck 2 of the bottle 1, as described therein. The cap is a double cap comprising an inner cap 11 and an outer cap 21 which is fitted over the inner cap 11. The inner cap 11 and the outer cap 21 are usually made of resin such as polypropylene, but are preferably made of a grade having high rigidity in order to suppress deformation when the caps are held. Further, it is preferable to use a surface-coating type or a mixing type antistatic agent in order to reduce friction between the inner cap 11 and the outer cap 21 and improve sliding between both caps.

A screw boss 3 for screwing the inner cap 11 is formed on the neck 2 of the bottle 1, and an annular anti-loosening flange 4 is formed below the screw boss 3.

The upper surface of the inner cap 11 is dome-shaped or the like, where a plurality of volatilization ports 12 of an appropriate size are perforated. The volatilization port 12 corresponds to a volatilization port 22 of an 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 the arrangement of the

volatilization ports

12 and 22 are arbitrary, and the long holes are not limited to the radial arrangement as shown in fig. 1, and various shapes and arrangements as exemplified in fig. 6 are possible.

An annular step portion 13 having step portions 14 at a plurality of locations is formed on the upper surface peripheral edge of the inner cap 11. The steps 14 are arranged at 4 positions at 90-degree intervals or at 2 positions at 180-degree intervals on the peripheral edge of the upper surface of the inner cap 11, for example, but may be arranged at other intervals. The steps 14 are inclined (see fig. 2 and 3), but in order to reduce the frictional resistance at the time of counterclockwise rotation as much as possible, it is preferable to make the inclined surface as gentle as possible. Further, a series or discontinuous annular projecting ring 15 is formed on the lower portion of the outer peripheral surface of the inner cap 11, a thread 16 corresponding to the thread 3 of the bottle neck 2 is formed on the inner peripheral surface thereof, and a series or discontinuous projecting strip 17 is formed on the lower side thereof. In the example shown in fig. 2, the ridge 17 is divided into 4 pieces.

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 plurality of volatilization ports 22 are formed as described above. On the upper portion of the inner peripheral surface of the outer cap 21, convex portions 23 (see fig. 2 and 3) sliding along the inclined surface of the annular step portion 13 are formed at 4 positions at 90-degree intervals or at 2 positions at 180-degree intervals. For example, the convex portions 23 are disposed every other at the positions where the volatilization ports 22 are formed (see fig. 2 and 3). Further, a ring groove 24 into which the projecting ring 15 of the inner cap 11 is fitted is formed in a lower portion of the inner peripheral surface of the outer cap 21, and an annular receiving portion 25 surrounding the ring groove 24 is formed below the ring groove (see fig. 2 and 3). The projecting ring 15 is fitted into 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 projecting ring 15.

The volatilization vessel according to the present invention is sold by packaging a bottle 1, a volatilization cap composed of an inner cap 11 and an outer cap 21, and granules put into the bottle 1 at the time of use, for example, with the bottle 1 filled with a liquid medicine and attached with a sealing seal to cover a temporary cap which is disposed after attachment. In use, the temporary cap is removed and the sealing seal is peeled off, and the granules are put into the bottle 1 to be chemically reacted with the liquid chemical. Then, 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, 22.

In the screw-mounting of the volatilization cap composed of the inner cap 11 and the outer cap 21, first, the outer cap 21 is pushed in over the inner cap 11, whereby the projecting ring 15 is forcibly slid into the ring groove 24. This operation can be achieved by the outer cap 21 having a certain degree of elasticity. Thus, the ring 15 is received in the ring groove 24 and locked thereto, and therefore the outer cap 21 cannot be removed from the inner cap 11.

In the state where the outer cap 21 is fitted over the inner cap 11 in this manner, the convex portion 23 provided on the inner peripheral surface of the outer cap 21 abuts against the inclined surface of the annular stepped portion 13 of the inner cap 11. Further, the outer cap 21 is rotatable with respect to the inner cap 11 because the projecting ring 15 is not closely received in the ring groove 24 but has a slight play.

However, when the convex portion 23 of the outer cap 21 is rotated so as to slide along the descending slope of the annular step portion 13 (normally clockwise), the convex portion abuts on the step 14 to prevent further rotation. On the other hand, when the rotation is performed in the reverse direction (normally counterclockwise), the convex portion 23 slides along the rising slope of the annular step portion 13, and thus can go over the step 14. That is, the outer cap 21 can be rotated (idly rotated) in this direction.

In a state where the outer cap 21 is attached to the inner cap 11 in a covering manner as described above, the inner cap 11 is screwed to the neck 2 of the bottle 1, but the screwing is achieved by rotating the outer cap 21. That is, if the outer cap 21 is rotated in the screw attaching direction, which is normally clockwise, the convex portion 23 abuts on the step 14, and the rotational force is transmitted to the inner cap 11 as it is. As described above, if 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 thread ridge 3 of the bottle neck 2 to advance spirally, and then the thread ridge 16 is screwed into the thread ridge 3 to advance spirally.

Eventually, the protrusion 17 comes into contact with the release prevention flange 4 to generate resistance, but if it is rotated strongly as it is, the protrusion 17 goes over the release prevention flange 4. The passage of the bead 17 over the locking bead 4 is not effected by a simple pushing-in, but by a screwing force, so that it can be carried out simply with a comparatively low force. If the ridge 17 passes over the release preventing flange 4 in this way, then the ridge 17 is firmly caught by the release preventing flange 4 and becomes unable to be pulled out.

In this way, in the case of the volatilization vessel according to the present invention, the container is replaced with a double-inside volatilization cap at the time of use, and if one end is fastened, the volatilization cap cannot be removed later, so that the occurrence of a situation in which the volatilization cap is accidentally detached and the contents flow out is avoided, and the volatilization vessel can be continuously used safely and hygienically for a long period of time, which is industrially highly applicable.
