Description

[Detailed description of the invention] Device and method for releasing volatile components of air treating gel The present invention] relates to a dispersion device, especially an air treatment device using a gel reservoir. The present invention relates to an apparatus and a method for controlling the amount of emission of a heating substance. Inventive Agriculture Iwa Applicable to any continuously acting air purification unit. and other expected applications are discussed.

Ability method to adjust the amount of fragrance emitted and increase the aroma effect in a closed space - Sky Among the various methods for air purification and fragrance release, this is the one that attracts the most attention. divergence Amount control (not just in terms of fragrance selection, but also in terms of the functional life of the individual) It is important even if

Fragrances can be expensive, so there is no cost-effective device (one that works efficiently). There must be. If the fragrance releases too quickly, the fragrance will be strong when you first use the product. Not only does it become too much, but when you finish using it, the remaining amount of fragrance that can be pulled up decreases. 1: To determine the subtle values of fragrance strength and product lifespan: emanation methods are compared multiple times using the same loading of perfume. With excellent technology By using a fixed amount of fragrance, you can maintain a stronger fragrance on your skin for a longer period of time than with the usual method. You can increase the effect.

The fragrance is dispersed in a matrix formed by a gel. production of continuously acting fragrance emitting devices in a desirable and relatively low cost manner. can. Gels usually range from very soft solids to non-cyclic gels called "cyclic gels." It includes a variety of things, including those that always have a high degree of physical connectivity.

Typical gel bases contain approximately 0.1:1 in anhydrous bases. 5 to about 10% by weight raw gel and about 0.2% to about 5% fragrance ingredients in an amount sufficient to hydrate the gel forming agent. include. Preferred gel-forming agents (Table: Radinan, Algin, Agar) and other carbohydrates such as amylose, sodium carboxymethyl cellulose can be mentioned.

Other ingredients include approximately 5% viscosity control WJ Qi L, and other desired gelling aids* IL For example, Potassium chloride Wet Qi L Fragrance volatilization retention sai L Increased amount? L Preservation Qi L Freeze-thaw stability (preferably contains dyes, etc.)

Air-treating gels can be used to remove volatile substances such as air purifying ingredients and deodorizing ingredients. The air treating component can be gradually released into the air. Commercially available saw [For gels such as], a gel mass that has been formed into an irregular shape in advance is shaped into a desired shape. It is generally placed inside a container or dispenser.

Dispensers for emanating the volatile components of such gels according to the prior art There are a wide variety of designs (from simple containers for gel blocks to relatively expensive ones). be. Inside a simple container, the gel disintegrates irregularly according to the wicking action, and (Friend) not only supports the mass, but also has a means of fixation to the desired surface, and the mass is usually unsightly. The design was designed to visually hide this, as it would easily collapse. high Various mechanisms are used to adjust the emission and action of the dispenser. Precise part & example (f, immersion that only allows the evaporated volatile components of the gel to pass through) It has a permeable diaphragm and a selectable filtration membrane.

In the prior art closest to the applied invention (above) a simple lidless container is used Volatile components contained in the gel] Top: Air flows from the surface of the gel through the opening of the container. released inside. Products with this kind of structure (friends) can be produced cheaply, but Not attractive. This is because the volatile components evaporate, so one gel is This is because it shrinks towards the bottom of the antenna, peels away from the sidewalls, and becomes unsightly and cracked. be. In addition, because of this structure, 1: Before the volatile components run out, There are often things we don't understand. Further 1: In a container like this (table [Because the gel shrinks]: The emission surface changes variously, resulting in the emission of volatile components. It becomes impossible to adjust the scattering.

An example of this simple container is shown in U.S. Patent No. 4.157.787. Ru. Here the opening of the container is covered with a layer of porous material.

One of the purposes of the present invention is to remove the surface area of a relatively inexpensive lidless container from a certain surface area. The volatile components of the gel are diffused into the air, and at that time, the surface of the gel 1:, the shrinkage of the gel is Although it may not be clearly visible, the volatile components of the gel are likely to run out at any time. methods and devices that clearly indicate that the item is missing or missing. It is about providing.

Another object of the present invention (in manufacturing a friend dispenser (:.

It is easy to fill and can be used at any point in time to evaporate the volatile components contained in the gel. An object of the present invention is to provide a method and a device that can be sealed.

According to the present invention, volatile products are evaporated by evaporation from the emanating surface of the gel. A dispenser will be supplied. Dispenser (top) Volatile products emit a lidless container defining an opening in the interior of the container; The gel container is attached adjacent to the entire perimeter of the opening and the gel is attached adjacent to the opening. Fixed to. This causes the diverging surface of the gel to be adjacent to the opening; During use, the gel inside the container, which acts as a reservoir, provides a stable emanating surface. For dispensing, the gel shrinks inside the container.

The present invention also provides a stable gel wicking surface for wicking volatile products. provide a method for This method (table: Fixing the gel in a structure surrounding the divergent surface ε) and, as volatiles evaporate, a gel reservoir replenishes the evaporative surface. .

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 11 (Partial sectional view of a part of still another embodiment of the dispenser of FIG. 4) It is.

Beginning 1: The prior art is explained with reference to FIGS. 1 and 2. The gel 3 that emits fragrance is filled into the antenna (Fig. 1), and the fragrance is emitted for a certain period of time. (Figure 2), the gel peels off from the container wall and cracks. , causing an invisible change in the divergence area.

Next 1: The patented invention will be explained with reference to FIGS. 3 to 6.

Before filling a wide-mouthed, cylindrical plastic container 5 with gel and dispersing it 1:, circular Around the opening 7 1: by tightly adhering an impermeable plastic seed door. and close the opening. A substitute for plastic sheet 9, which is closely attached to container 5. A vertical hemispherical lid may also be used. This lid (to make the dispenser work) 1: Can be removed. From the bottom of the container] Filling port 1] 3, heat to liquid form. The gel 3 is injected through the nozzle 15 and filled into a container (FIG. 3).

After filling the container with the gel agent, the filling port 13 is sealed with a plug 17, and as shown in FIG. 1: Place it upside down as shown in Figure 3. Inside the container 5] Around the opening 1: A porous polyethylene band with holes] 9 is fixed. This obi (friend example) (Is it fixed by adhesive or welding, or is it cast when casting the container? Alternatively, it may be formed as a porous part of the container material itself. (It only needs to function as an integrated part with the container. The width of the band is 1. During use, the tape may shrink and become detached from the strip or sit in a low position in the container. To fix a certain gel so that it does not get drawn into the divergent surface 21. It is wide enough. The width of the band is 15-30% of the opening diameter and/or A suitable value is 20-40% of the height of the container. Liquidized gel in container 5 When filling the gel, the gel penetrates into the gaps in the band] 9 and is fixed to the band during solidification.

When the gel solidifies and the plug 13 is attached to the filling port] 3, the dispersion device can be packaged. condition and the volatile compounds will not be reduced before use of the dispenser.

Because the band 19 has a gel attachment part, the gel can be removed during operation of the dispenser. The divergence surface 21 of the container remains stable and close to the top of the container. Ru. This goes against the gel's natural tendency to shrink in all directions.

If there is no attachment part on the band, the gel will shrink inside the container and turn around. Obi removed By supporting the top of the gel, the gel (which is not attached to the band) Since it always supplies a divergent surface even without it, it functions as a reservoir, and at the same time 1:, It will be reduced step by step. However, the entire exposed gel shrank in a very ugly way. However, unlike commonly available devices, the shrinkage occurs inside the container and the divergence surface Surface area (the surface does not change substantially. The strip has an attachment part, so the dispenser - in an upright position as shown in Figures 4, 5, and 6, or in an upside-down position as shown in Figure 3. , or in any desired position (for example, attaching the bottom of a container to a wall) be able to. gel (, t, other than the part that is adhered to band 19) (of the container) Not attached to internal surfaces and thus acts as a reservoir to replenish the divergent surface It is desirable to be able to do so. Flexible plastic sheet 9 (no distortion when filling the device) to form a hemispherical diverging surface. By this, when you first start using it, you can Even if a slight shrinkage occurs, the surface (i.e., substantially the same plane as the periphery of the opening 7) This results in a smooth surface (Figure 5). This flat surface (if it shrinks further, it will have a slight dent Convexities occur, but the shape of the hemisphere formed during the initial filling determines the extent to which these convexities occur. decrease.

In the dispenser of the present invention, the agricultural plastic sheet 9 is peeled off from the opening. Figure 4), exposing the diverging surface of the gel. Here, the volatile components of the gel are transferred from the emission surface to the surrounding area. evaporates into the atmosphere, and at this time the divergent surface undergoes initial contraction, resulting in the shape shown in Figure 5. Forms a substantially flat surface. As volatile components evaporate from the surface, the gel becomes coagulated. It contracts from the bottom 11 of the antenna to continuously supply volatile components to the emanating surface. Figure 5 A decorative lid for the opening is shown in the figure, but this may be optionally provided for decorative purposes. This is necessary or desirable for the operation of the dispenser of the present invention. It's not a good thing.

As the gel (top) decreases, it begins to shrink from the bottom of the container, and the surface of the gel comes into contact with air. The area continuously shrinks as volatile components evaporate. all the energy As the volatile components evaporate, the non-volatile components of the gel rise to the level of the absorbent band. (Figure 6). an opaque absorbent fixation strip in a transparent plastic container]9 If you look at the device from the side, you will see that it is empty and that it needs to be replaced. It becomes a clear landmark.

Band 19 (top inside container 1:, adjacent to opening 7 and fixed with adhesive) , a semi-rigid porous material such as porous polyethylene is preferred. but, Instead of porous plastic 1mm, as well as a strip with many protruding loops 1:, Using other porous materials such as non-woven fabrics, woven fabrics, felt, or foamed polymeric materials You can also do that. of the container having means for securing the gel adjacent to the opening; An example of a possible structure is shown in FIG. 9, 1o, 1].

In FIG. 9, a large number of flanges 23 are arranged vertically at intervals around the entire periphery of the box. It has an opening and is designed to fix the solidified gel at the rear of the opening. ing. Surrounding flange 23 (attached to the outer wall of the upper container 5 by webs 25) However, these webs 251 are not essential. web Cross section 1. t, need not be rectangular as shown. For example (Dai fixed knot) Minimize the amount of gel fixed to the rear of the flange 23 without compromising integrity. (Mi) The wall surface may have a curved pyramidal cross section.

This modification is shown in FIG. In this modification (on the friend flange 231) It has a truncated pyramid cross section with the minimum width of the part that connects to the wall of the container 5, and A dovetail groove-shaped opening 27 is formed that extends vertically from the opening of the hole toward the bottom 1. Ru. At the top of the vertical length of the flange 23, place the gel in the opening 7, similar to the one with a porous zone. is of sufficient length to be secured to the container adjacent to the 'This allows the It shrinks from the gel container between the lunge and the bottom 1 and provides a divergent surface.

Yet another modification is shown in FIG. In this variant (above a large number of annular A flange 29 extends vertically from the opening toward the bottom 11, and an annular hole 3 is formed at the rear of the flange 29. 1 to fix the gel to the container with this filling of the container. Ru. The outer threaded portion adjacent to the floor opening 7 in this embodiment is shown in FIG. It is designed to fix a decorative lid such as

The porous plastic strip shown in Figure 3.4.5.6 has a rectangular cross section, but the diverging surface It may also have a tapered shape adjacent to the opening 7 to increase the product (Fig. 8 reference).
