Description

[Detailed description of the invention] FIELD OF THE INVENTION This invention relates to luminescent latex articles, and more particularly to luminescent condoms.

As used herein, the term "luminescence 1" includes phosphorescent and fluorescent products. It is. Based on this invention, the article preferably has at least 2. It emits light for 3 minutes. Chemically generated products that are toxic are not preferred.

According to the first feature of the invention, the step of making a luminescent condom involves and a non-toxic luminescent compound, immerse a mold frame in the mixture, and place the mold on the layer frame. Remove the mold frame to leave a coating of the mixture on the vulcanizing the coating to form a film.

A preferred feature of the invention is that the mold frame is soaked and substantially Coating a luminescent latex composition in a latex composition that does not contain luminescent compounds It consists of a process of As another embodiment of this invention, the luminescent latex The composition may be placed between the inner and outer latex-free layers. These things Because of the constituent components of the luminescent latex, it helps to minimize physiological effects. The standing mold frame is first partially dipped into a luminescent latex mixture or compound. Preferably, the material is then immersed more deeply into latex that does not contain luminescent compounds. It is preferable to let With this, the outer peripheral surface of the condom contains the luminescent compound. It will be sealed with no latex.

Preferred latexes have a medium modulus, i.e., those used for making immersed articles. There is a natural rubber that is pre-vulcanized.

The luminescent composition is selected from a large number of applicable luminescent compounds. of the compound Mixtures can also be used. The composition is non-toxic and physiologically Preferably, those that do not cause chemical effects on Compositions based on zinc sulfide, especially Copper-containing zinc sulfide is particularly preferred. For example, quotient 1 [IU group LUX (Hoechst) In particular, the composition sold as LUMILUX N is extremely effective. It is clear that The latter composition is stimulated by shortwave daylight or artificial light. Shows yellow-green phosphorescence.

Chemiluminescent, or other self-energetic, luminescent compounds are known for their toxicity and Preferred due to difficulty in incorporating into latex without reducing strength. do not have. Cadmium compounds, which are considered toxic, are not preferred. In addition, conventional computers Luminescent coatings used on the outside of the dome are equally dangerous and should not be used. do not have.

The luminescent composition may be provided in particulate form or as a suspension in a fluid.　1O-60mi A particle size of 50 microns, especially IO, has been found to be suitable.

Smaller particle sizes may hinder luminescent properties from providing a smooth surface. If not, it is particularly preferred for making condoms.

Percentages in this specification are by weight unless otherwise indicated.

Single or multiple concentrators to keep luminescent compounds in suspension in latex can be used. Precipitation of the luminescent compound during fabrication results in unvulcanized latex composition The service life of the product is greatly reduced. Longer time to maintain solids in suspension Vigorous agitation is determined based on the flow characteristics of the latex.

The thickening agent is preferably non-toxic, tasteless and does not adversely affect the photochemical properties of the composition. It is preferable to use one that does not give Methyl cellulose thickener, e.g. carboxylic acid Methyl cellulose that has been prepared can be used. Other concentrating agents include: Karaya rubber, polyacrylate, sodium alginate, etc. This is known to car manufacturers.

The luminescent composition may contain a single or optionally multiple photosensitizing or enhancing agents.

The luminescent latex mixture is a latex having a luminescent composition of 20%-50%; Preferably consisting of 20%-40%, more preferably 30%-40% of said composition. Finishes, such as polydimethylsiloxane (e.g. DIMETHICONE C1) 1) can be used to improve the appearance of products.

Colorants, flavors, fillers or other additives may also be used if desired.

A second feature of the invention is that the lamp contains a filler consisting essentially of a particulate luminescent compound. The purpose of the present invention is to provide a luminescent condom made of TEX.

Said luminescent layer preferably comprising zinc sulfide or copper-promoted zinc sulfide as described above. The compound may incorporate a thickening agent to facilitate dispersion of the solid phase within the latex. is preferable.

Preferred condoms contain 20-50%, preferably 20-40%, particularly preferably It incorporates a luminescent latex consisting of 30-40% luminescent compounds.

Male or female condoms can be provided.

Condoms can be formed into simple conventional configurations or into undulations or other novel shapes. It is. The condom according to the present invention is based on the first feature of the invention described above. The shape shall emit light as a whole, or it shall emit light partially, and the remaining part shall be a It may also be formed from conventional non-luminous latex. The shape part of the new condom is a luminous group may be formed of a composition.

Condoms according to this invention offer numerous advantages. Increased: I'm looking forward to it. In addition to its value, proper use in the dark may be facilitated. In addition, the new product The value as a discipline or pleasure is the irritation of using it for prevention against disease. It is intended to alleviate the situation.

Furthermore, it is possible to see if the condom has come off during intercourse.

This invention will be described below based on Examples, but it is limited only to these Examples and cannot be put into practical use. Example 1 Contains carboxymethyl cellulose (1% of a 5% aqueous solution) with a particle size of 10 microns IUMILUX N (4,0kg) and unadded 7-/x (10kg, 6 (0% solids) was combined using a mechanical blender. The condom is Using a conventional chain conveyor device, the glass mold is placed in the latex mixture. of silicone oil lubricant soaked twice in the bath, vulcanized by infrared radiation, and applied. made from the mixture by applying a coating. The condom has a shape It was removed and emitted phosphorescence for a long time after excitation.

Example 2 LUMILIJX N (2,0kg 40 micro 7) unvulcanized 5 tear (13 kg, 60% solids) and as described in Example 1. It was molded. Synthetic condoms emitted phosphorescence for a long time.

Example 3 Unvulcanized, pre-vulcanized natural latex (PREVUL 5396 M Vital iquid Polymers LLd, 50kg) LUMILUX N (5 0 kg 40 microns) and carboxymethyl cellulose (1% of 5% aqueous solution) The containing composition is formed into condoms using a fully automated batch production machine. Ta. Glass 7-ohm is diluted with hydrogen chloride # (1%), water, and calcium nitrate solution. It was purified by immersion inside. The layer frame was then soaked with granulated talc in methanol. It was immersed in the containing suspension and further dried in an oven. Inorganic substances are mold release agents Acts as. Next, the mold frame is continuously coated with latex and luminescent compound. immersed in the mixture and then immersed in clean latex with no fillers added. It was. The 7 ohm is deeper than 8 immersion in latex containing luminescent compounds. immersed in latex without luminescent compounds. Rotate the composition using a rotation plan. After automatic beading and drying, the product is wet-stripped. and removed it from the former. Soak the condom in circulating cooling water and dry it. Ta.

The former rotates axially on a swivel to promote beading and The tip can be rotated around the shoulders of the condom. Two rotating brushes are used It is possible to use it.

Example 4 Example 3 using a similar latex composition with 0.03% temperature indicator added. The principles stated were repeated. The 7 ohms were heated from 40 degrees to 60 degrees. .

The product was made as described in Example 3.

Other manufacturing methods known to those skilled in the art may also be used. For example, 1 immersion , coagulation dipping, anodic dipping, and casting, Kaysam It is a process.
