Description

Insect repellent device

technical field

The invention relates to the technical field of deworming, in particular to a deworming device with a deworming medicinal tablet.

Background technique

Cockroaches, ants, borers and other pests can spread diseases and affect people's normal life and work. At present, the main means of preventing and controlling cockroaches and other pests include the use of insecticidal sprays, insecticidal baits, and trapping devices. It is poisoned to death after being baited. This method has high insecticidal efficiency, but there are drawbacks. Since the insecticidal bait contains toxic components, there is a danger of accidental ingestion after contacting the above-mentioned insecticidal bait, especially if there are children and pets at home, it is easy to appear Accidentally ingesting poisonous baits can endanger life and health. In addition, cockroaches and other pests will not be poisoned immediately after eating poisonous insecticidal baits, and they will crawl around after contact with poisonous baits, bringing toxic ingredients to cabinets, food storage cabinets, etc., thus affecting life and health. For this reason, the use of repellents to drive off pests has also appeared on the market. For repellents, toxic chemical components were used in the past to improve the effect of repelling pests. System and skin damage. With the improvement of people's awareness of environmental protection, the repellents of plant extracts play a more important role in the prevention and control of pests. For example, in the patent document with the publication number CN104255824A, a method for preparing cockroach repellent tablets from the essential oil of Zanthoxylum bungeanum is proposed. In the patent document of CN202819423U, a deworming box containing moth balls is proposed, but the above-mentioned deworming ingredients are relatively simple, and there are problems such as poor deworming effect, easy damping of medicaments, and difficulty of lasting and effective for medicaments in actual use.

In addition, in the existing insect repellent device, the structure of the drug tablet is relatively simple, and it is a single-layer sheet or block structure. The concentration of the volatilized medicament is getting lower and lower, the insect repellent effect is getting worse and worse, and it is difficult for the medicament tablet to have the insect repellent effect for a long time, resulting in problems such as short effective use time of the insect repellent device. In the patent document TWM557981U, a long-acting insect repellent and anti-mosquito hanging sheet structure is described, which is composed of front and rear barrier layers and a diffusion layer in the middle. The diffusion layer can absorb liquid substances and gradually diffuse and volatilize them. There are a plurality of capsule particles containing insect repellent components inside the layer. When necessary, the capsules are squeezed one by one so that the internal insect repellent components seep out and are adsorbed and volatilized by the diffusion layer to achieve the effect of long-term insect repellent. However, the insect repellent device of this document needs to be provided with a capsule structure, the production process is complicated, and the capsules need to be manually squeezed one by one to achieve the effect of long-term insect repellent, which is inconvenient to use.

In addition, in order to make the medicinal tablet have a better repelling effect, the medicinal tablet is generally impregnated and adsorbed with a variety of anthelmintic ingredients. However, when a variety of pesticide ingredients are mixed, a chemical reaction will occur, and the composition of the anthelmintic agent will change, which will weaken the repellent. Insect repellent effect, especially after three or more liquid pharmaceutical ingredients are mixed, the chemical composition of the pharmaceutical ingredients will change greatly and the stability will be poor, thus affecting the insect repellent effect.

In the patent document with the publication number of CN1918982A, it proposes a pest repelling device. The medicament has good volatility, but the device structure is complicated and the cost is high, which is not conducive to popularization and use. The hands need to be in direct contact with the tablet, and after the user's hands touch the tablet, they need to be cleaned, which brings trouble to use. In the patent document TW522791U, it proposes an accommodating box for accommodating bait, which pre-closes the space between the base and the top cover when leaving the factory, so as to achieve the purpose of packaging the bait and prolong the shelf life of the bait. When the bait is used, it is only necessary to rotate the top cover to form an open opening for the pests to enter and exit, and the user will not come into contact with the bait, which can effectively improve the convenience and safety of use. Although it can prevent consumers from directly contacting the bait agent, the accommodating box has a complex structure, and since there is no packaging to seal the package, it is difficult to ensure its tightness, and there are problems such as moisture in the box, which affects the performance of the bait.

Therefore, there is a need for a deworming device that is safe, effective, durable and convenient to use.

SUMMARY OF THE INVENTION

In order to solve the problems of the complex structure of the anthelmintic device in the prior art, the unhealthy and environmental protection of the anthelmintic medicament, the poor anthelmintic effect of a single medicament tablet structure, the inconvenience caused by the need to contact the medicament during the use process, and the like, the present invention provides a healthy, environmentally friendly, The insect repellent device with long-lasting medicinal effect, good insect repelling effect and convenient use.

In order to achieve the above object, the present invention adopts the following technical solutions:

An insect repellent device, comprising a shell and a medicament tablet accommodated in the shell, the surface of the shell is provided with a plurality of through holes communicating with the inside of the shell, the medicament tablet can volatilize to generate insect repellent gas, and is characterized in that , the medicine tablet has a multi-layer structure, including: a first liquid absorption layer, which adsorbs a liquid volatile insect repellent agent; a second liquid absorption layer, which is adsorbed with the same or different liquid as the first liquid absorption layer. Volatile insect repellent agent; a solid or semi-solid slow-release layer disposed between the first liquid absorption layer and the second liquid absorption layer, which contains the volatile insect repellent agent.

A solid or semi-solid slow-release layer is arranged between the first liquid absorbing layer and the second liquid absorbing layer. Since the first liquid absorbing layer and the second liquid absorbing layer adsorb liquid volatile drugs, the solid Or the volatile agent of the semi-solid slow-release layer can be gradually dissolved slowly to form a liquid agent under the infiltration of the liquid volatile agent, and under the action of capillary attraction, it can flow up and down the liquid absorbing layers on both sides, so that the upper and lower sides of the liquid can be absorbed. The liquid-absorbing layers on both sides can continuously supplement effective insect repellent ingredients, and contain effective insect repellent agents for a long time to ensure the stability and durability of the insect repellent effect. In addition, each liquid absorbing layer can absorb different chemical components, respectively volatilize to produce different insect repellent odors, which can avoid the problem that the single-layer pharmaceutical tablet absorbs multiple insect repellent components and causes chemical reaction, resulting in poor insect repellent effect.

The pharmaceutical tablet also includes a third liquid-absorbing layer on the side of the first liquid-absorbing layer or the second liquid-absorbing layer, which adsorbs a liquid volatile insect repellent agent, and the third liquid-absorbing layer is connected to the first liquid-absorbing layer or the first liquid-absorbing layer. A solid or semi-solid slow-release layer is arranged between the second liquid absorbing layers, which contains a volatile insect repellent. By arranging multiple liquid absorbing layers and solid or semi-solid slow-release layers, the tablet contains more insect repellents, and the medicinal effect is more durable.

The liquid volatile insect repellent agent adsorbed by the liquid-absorbing layer includes one or more components selected from the group consisting of peppermint essential oil, camphor essential oil or citronella essential oil. The use of natural plant insect repellent ingredients as the insect repellent makes the insect repellent effect good, environmentally friendly and healthy. In addition, the use of essential oils as the main carrier enables the medicament to be stably adsorbed on the liquid absorbing layer, and can be gradually volatilized, ensuring the lasting volatilization of the medicament. sex.

The volatile anthelmintic agent of the solid or semi-solid slow-release layer contains camphor and/or citronella extract. The volatile insect repellent agent in the slow-release layer can be solid powder, and is wrapped by a hygroscopic material to form a slow-release layer. The hygroscopic material has good hygroscopicity and permeability. The liquid layer adsorbs liquid volatile agents, especially those impregnated with plant essential oils, so the solid powder can be gradually dissolved under the infiltration of plant essential oils to form liquid agents, and under the action of capillary attraction, the upper and lower liquid absorbing layers Flow, so that the liquid-absorbing layers on the upper and lower sides can continuously replenish effective insect repellent ingredients, and contain effective insect repellent agents for a long time to ensure the stability and durability of the insect repellent effect. In addition, the solid or semi-solid slow-release layer may also contain water-absorbing particles, such as calcium chloride, alumina, diatom mud, and the water-absorbing particles are mixed with volatile insect repellents to form a solid block slow-release layer, or the like The semi-solid slow-release layer of the gel can also be gradually dissolved into a liquid medicine under the infiltration of plant essential oils, and under the action of capillary attraction, it flows up and down the liquid-absorbing layers on both sides, making the liquid-absorbing layers on the upper and lower sides. The layer can continuously replenish the effective insect repellent ingredients.

The materials of the first liquid-absorbing layer, the second liquid-absorbing layer and the hygroscopic material are chemical fiber, cloth, cotton, paper, sponge or non-woven fabric. For the material of the liquid-absorbing layer, other materials than the above-mentioned materials can also be used, as long as they have certain hygroscopicity.

When the first liquid-absorbing layer and the second liquid-absorbing layer are adsorbed and impregnated with the same volatile insect repellent, the volatile insect repellent may include at least two components selected from the above-mentioned group. Since the insect repellent effect is better when a plurality of insect repellent components are mixed, it is preferable to adsorb and impregnate two or more insect repellent components that do not react. However, chemical reactions will occur between different insect repellent components, especially when three or more insect repellent components are mixed, the composition of the chemical will change, thereby reducing the insect repellent effect. The various components are adsorbed and immersed in each liquid absorbing layer respectively, and each liquid absorbing layer separately releases different insect repellent odors, for example, the volatile insect repellent agent adsorbed by the first liquid absorbing layer includes a component selected from the above group, The volatile insect repellent agent adsorbed by the second liquid-absorbing layer and/or the third liquid-absorbing layer includes at least one component selected from the above-mentioned group that is different from the aforementioned liquid-absorbing layer. The two liquid absorbing layers adsorb different insect repellents respectively, and produce different insect repellent smells respectively, which can also produce a better comprehensive insect repellent effect.

The pharmaceutical tablet is covered by a package when it leaves the factory, and the package has flat parts located at both ends in the longitudinal direction that are not covered with the pharmaceutical tablet, and a bulging part that is located between the flat parts at the two ends and covered with the pharmaceutical tablet. Two opposite ends of the casing are respectively provided with openings, the length of the opening is greater than the width of the package, and the height of the opening is greater than the thickness of the flat part and less than the thickness of the bulging part , when the package is placed into the housing, the flat parts at both ends of the package in the longitudinal direction extend out from the openings at both ends of the housing.

The pharmaceutical tablet of the present invention is sealed and packaged by the package when it leaves the factory, so there will be no volatilization and leakage of the pharmaceutical tablet, oxidation and deterioration of the pharmaceutical, etc., and the stability of the pharmaceutical effect can be ensured. When the package covered with the pharmaceutical tablets is placed in the casing, the flat parts at both ends in the longitudinal direction extend from the openings at both ends of the casing, and one end of the extended package is torn or cut to form an opening, Pull the other end, because the vertical height of the opening is greater than the thickness of the flat part and less than the thickness of the bulging part, so the opening can only allow the flat part of the package to pass through, but not the coated medicament The tablet passes through, so as the other end of the package is pulled, the drug tablet slides out of the opening formed by tearing or cutting one end of the package and remains inside the housing. The whole process does not need to touch the tablet, so it is convenient to use, healthy and pollution-free.

The casing is composed of an upper casing and a lower casing, and the upper casing and the lower casing are connected by a detachable structure. By arranging the upper and lower housings to be connected in a detachable structure, for example, the upper and lower housings are connected by a snap connection structure, which facilitates production and assembly. When leaving the factory, the package covered with the tablet is placed between the upper and lower housings. The user only needs to tear one end of the package and pull the other end to place the tablet into the housing without contact. When the expiration date of the tablet is up, the upper and lower casings can be opened, and new packaging can be placed in it, so that the casing can be reused and the service life of the product can be increased. When the upper and lower shells are used, it is only necessary to form a concave portion on the edge of the end of one shell. For example, the concave portion is only provided on the end edge of the lower shell, and the end of the upper shell is flat. When the upper and lower shells are connected together , a tiny opening or gap can be formed at the end. In addition, the upper and lower casings can also be fixedly connected in a non-detachable manner, and the package is put into them before the fixed connection. Of course, the casing can also be integrally formed, and by arranging an opening and closing cover on the casing, etc., there is no limitation on the method of putting the package into the shell, as long as the package can be put into the shell. .

An incision or a cutting indication mark is provided on the flat part of one end extending out of the casing in the length direction of the package, and a pulling indication mark is provided on the flat part of the other end, and the other end is provided with an anti-slip pattern. By arranging a slit or a cutting indicator on the flat part of one end extending out of the casing in the length direction of the package, it is convenient for the user to tear the package along the incision to form an opening, or cut the package along the cutting indicator to form an opening. The other end is provided with a pulling indication mark, such as an indication arrow, to facilitate the user to identify the pulling direction. Prevent slippage when pulling the package by setting the anti-skid pattern.

The beneficial effect of the invention is that: the pharmaceutical tablet has a multi-layer structure, including multi-layer liquid absorption layers and solid or semi-solid slow-release layers arranged between the liquid absorption layers. Therefore, the volatile agent in the solid or semi-solid slow-release layer can be gradually dissolved under the infiltration of the liquid volatile agent to form a liquid agent, and under the action of capillary attraction, it flows up and down the liquid absorbing layers on both sides. The liquid-absorbing layers on the upper and lower sides can continuously supplement effective insect repellent ingredients, and contain effective insect repellent agents for a long time to ensure the stability and durability of the insect repellent effect. The multi-layer liquid-absorbing layer can absorb the different components of the medicine respectively, and release different insect repellent smells respectively, and the insect repellent effect is more stable. A variety of natural plant insect repellent ingredients are used as insect repellents, which makes the insect repellent effect good, environmentally friendly and healthy. In addition, the use of essential oils as the main carrier enables the medicament to be stably adsorbed on the liquid-absorbing layer, and can be gradually volatilized, ensuring the volatilization of the medicament. persistence.

Detailed ways

The present invention will be further described in detail below in conjunction with accompanying drawings 1-7. In Figures 2-5, the structure and use process of the present invention are illustrated in the state where the shell is open. This is only to facilitate the understanding of the structure of the insect repellent device. In actual use, the shell is in a closed state, for example, the upper and lower shells are snap-fitted and assembled. together state. In addition, the shape of the package 2 covering the drug tablet 6 and the shape of the drug tablet 6 are only schematic diagrams, and not the actual state.

As shown in FIG. 2 , the insect repellent device of the present invention includes a casing 1 and a medicinal tablet 6 . The surface of the casing is provided with a plurality of through holes 3 communicating with the interior of the casing. The medicinal tablet is detached from the package and placed on the The shell 1 can volatilize and generate insect repellent gas, and the above insect repellent gas is emitted from the through hole 3, so as to achieve the effect of repelling insects. Referring to FIG. 6, the drug sheet 6 has a multi-layer structure, including a first liquid absorbing layer 6-1, which adsorbs a liquid volatile insect repellent agent; a second liquid absorbing layer 6-2, which adsorbs the first liquid absorbing layer 6-2 Liquid-like volatile insect repellents with the same or different liquid-absorbing layers; further comprising a solid-like or semi-solid slow-release layer 6-3 disposed between the first liquid-absorbing layer and the second liquid-absorbing layer, which contains Volatile repellent. A solid or semi-solid slow-release layer 6-3 is arranged between the first liquid-absorbing layer 6-1 and the second liquid-absorbing layer 6-2, since the first liquid-absorbing layer 6-1 and the second liquid-absorbing layer 6-2 Adsorbs liquid volatile agents, so the volatile insect repellent agent in the solid or semi-solid slow-release layer 6-3 can be gradually and slowly dissolved under the infiltration of liquid volatile agents to form liquid agents. Under the action of capillary attraction, the liquid-absorbing layers on the upper and lower sides flow, so that the liquid-absorbing layers on the upper and lower sides can continuously replenish the effective insect repellent ingredients, and contain effective insect repellent agents for a long time to ensure the stability and durability of the insect repellent effect.

The pharmaceutical sheet 6 also includes a third liquid-absorbing layer (not shown) located on the side of the first liquid-absorbing layer or the second liquid-absorbing layer, which adsorbs volatile insect repellents, and is connected with the first liquid-absorbing layer on the third liquid-absorbing layer. A solid or semi-solid slow-release layer 6-3 is arranged between the liquid layer or the second liquid absorption layer, which contains a volatile insect repellent. In addition, fourth and fifth liquid absorbing layers (not shown) may also be provided, and a solid or semi-solid slow-release layer may be provided between the liquid absorbing layers.

By arranging multiple liquid-absorbing layers and solid or semi-solid slow-release layers, the multiple liquid-absorbing layers make the tablet 6 contain more insect repellents compared to the single-layer drug tablet in the prior art. In addition, a solid or semi-solid slow-release layer including volatile insect repellents is arranged between the liquid absorbing layers, so that the upper and lower liquid absorbing layers can continuously replenish effective insect repellent ingredients, so that the volatilized insect repellent tablets are free from insects. The anthelmintic smell is basically the same at the beginning of use and after a period of use, so that the concentration of the anthelmintic gas volatilized during the entire use cycle of the tablet has little difference before and after, so that the efficacy of the drug is lasting and the service life is longer.

Referring to FIG. 7 , taking the single-layer pharmaceutical tablet in the prior art as the control tablet, the present embodiment adopts a three-layered pharmaceutical tablet, both of which have the same volume and size, and an airtight test box is used, and the newly unsealed pharmaceutical tablet is placed in an airtight test box. The gas concentration after standing in the test box for 1 hour is regarded as 100% of the original concentration, and then it is taken out of the closed test box for normal use. Every 5 days, the concentration and the concentration after standing in the closed test box for 1 hour are re-recorded. The ratio of the original concentration, after the test, take out the external device and use it normally. It can be seen from FIG. 7 that the decreasing rate of the concentration of the volatile gas of the multi-layer pharmaceutical tablet in this embodiment is significantly slower than that of the single-layer insect repellent tablet of the same volume in the prior art.

In addition, each liquid absorbing layer can adsorb different pharmaceutical ingredients respectively, and volatilize respectively to produce different insect repellent smells, so that various insect repellent pharmaceuticals are volatilized to produce a better comprehensive insect repellent effect. In this way, it can be avoided that the single-layer pharmaceutical tablet adsorbs a variety of anthelmintic ingredients, especially three or more anthelmintic ingredients, and chemical reactions occur, and the anthelmintic ingredients change, which makes the stability of the mixture poor, resulting in poor deworming effect. question.

Through the deworming model test, it was found that grouping experiments were carried out under the same experimental conditions, and cockroaches with the same model conditions were selected for the two groups of experiments. All cockroaches move away from the multi-layer tablet quickly. In another group of experiments, the cockroaches did not respond as strongly to the prior art tablet with a single component or a mixture of multiple drugs as the first group, and it took longer for all cockroaches to stay away from the tablet than the first group. length. Therefore, compared with the insect repellent pharmaceutical tablet in the prior art, the insect repellent effect of the multi-layer pharmaceutical tablet in this embodiment is significantly improved. The deworming model test is shown in Table 1 below:

Embodiment 1 is a three-layer structure, the first and second liquid absorbing layers both absorb camphor essential oil, and the slow-release layer contains camphor; Embodiment 2 is a three-layer structure, and the first and second liquid absorbing layers adsorb camphor essential oil and Peppermint essential oil, the sustained-release layer contains citronella extract; Example 3 is a five-layer structure, three liquid-absorbing layers adsorb camphor essential oil, peppermint essential oil and citronella essential oil respectively, and two sustained-release layers respectively contain camphor and citronella extract. Comparative Example 1 is a single-layer, single-component (impregnated with camphor essential oil) pharmaceutical tablet of the same volume size; Comparative Example 2 is a single-layer, multi-component (impregnated with camphor essential oil and peppermint essential oil) pharmaceutical tablet of the same volume size . The test conditions include a semi-closed box, a partition plate is set in the middle of the box, a plurality of openings that can be opened and closed at the lower end of the partition plate are provided for cockroaches to crawl through, and the partition plate divides the box into two parts . At the beginning of the experiment, a certain number of cockroaches were placed in the first part of the box, and the opening was closed, and then a tablet was placed in the first part of the box, and the opening was opened at the same time, and the timing was from this moment until all the cockroaches escaped. The time required from one part to the second part of the box, in seconds. It can be seen from Table 1 that the cockroaches have the strongest response to the multi-layer structure in this example and the pharmaceutical tablets that adsorb different pharmaceutical components. Even with the three-layer structure, the same essential oil is adsorbed, and the insect repellent effect is better than that in the comparative example.

Table 1

The volatile insect repellent agent adsorbed by the liquid-absorbing layer includes one or more components selected from the group consisting of peppermint essential oil, camphor essential oil or citronella essential oil. The use of natural plant insect repellent ingredients as the insect repellent makes the insect repellent effect good, environmentally friendly and healthy. In addition, the use of essential oils as the main carrier of the drug enables the drug to be stably adsorbed on the liquid-absorbing layer, and can gradually volatilize slowly, ensuring the volatilization of the drug persistence.

The volatile anthelmintic agent of the solid or semi-solid sustained-release layer contains camphor and/or citronella extract (extract). The volatile insect repellent of the solid or semi-solid slow-release layer can be solid powder, and the slow-release layer is formed by wrapping the hygroscopic material. The hygroscopic material has good hygroscopicity and permeability. The liquid-absorbing layer and the second liquid-absorbing layer are adsorbed with liquid volatile agents, especially those impregnated with plant essential oils, so the solid powder can be gradually dissolved under the infiltration of plant essential oils to form liquid agents, and under the action of capillary attraction, upwards. The liquid-absorbing layers on the lower two sides flow, so that the liquid-absorbing layers on the upper and lower sides can continuously replenish effective insect repellent ingredients, and contain effective insect repellent agents for a long time to ensure the stability and durability of the insect repellent effect. In addition, the solid or semi-solid slow-release layer may also contain water-absorbing particles, such as calcium chloride, alumina, diatom mud, and the water-absorbing particles are mixed with volatile insect repellents to form a solid block slow-release layer, or the like The semi-solid slow-release layer of the gel can also be gradually dissolved into a liquid medicine under the infiltration of plant essential oils, and under the action of capillary attraction, it flows up and down the liquid-absorbing layers on both sides, making the liquid-absorbing layers on the upper and lower sides. The layer can continuously replenish the effective insect repellent ingredients.

The material of the liquid-absorbing layer and the hygroscopic material is chemical fiber, cloth, cotton, paper, sponge or non-woven fabric. Other materials than the above-mentioned materials can also be used, as long as they have certain hygroscopicity.

When the first liquid absorbing layer 6-1 and the second liquid absorbing layer 6-2 are adsorbed and impregnated with the same volatile insect repellent, the volatile insect repellent may include at least two components selected from the above-mentioned group. Since the insect repellent effect is better when a plurality of insect repellent components are mixed, it is preferable to adsorb and impregnate a mixture of two or more insect repellent components that do not react chemically. However, when there is a chemical reaction between different anthelmintic ingredients, especially when three or more anthelmintic ingredients are mixed, the composition of the anthelmintic agent changes, which makes the mixed agent less stable, resulting in poorer anthelmintic effect. By immersing the mixed insect repellent ingredients, each ingredient is adsorbed and impregnated on each liquid absorbing layer, and each liquid absorbing layer separately releases different insect repellent odors. For example, the volatile insect repellents adsorbed by the first liquid absorbing layer include: One component selected from the above-mentioned group, the volatile insect repellent agent adsorbed by the second liquid-absorbing layer and/or the third liquid-absorbing layer includes at least one component selected from the above-mentioned group that is different from the aforementioned liquid-absorbing layer. The two liquid absorbing layers adsorb different insect repellents respectively, and produce different insect repellent smells respectively, which can also produce a better comprehensive insect repellent effect.

The pharmaceutical tablet 6 is covered by a package 2 at the time of delivery, and the package 2 has a flat portion 4 located at both ends in the longitudinal direction that is not coated with the drug tablet, and a bulge portion located between the flat portions 4 at both ends with the drug tablet coated. 5. The material of the package 2 can be a material with water resistance such as plastic film or aluminum film, the package can be transparent or non-transparent, and the end of the package is heat-sealed to form a sealed package. Since the drug tablet is sealed and packaged , so the part that coats the tablet 6 will bulge, thereby forming a bulging part 5. The bulging part 5 in the accompanying drawings is only a schematic representation of the bulging part 5 formed there by the package, not the actual package. The state in which the tablet 6 is coated. A flat portion is formed at the position where the drug tablet is not coated at both ends in the longitudinal direction of the package 2, and the end of the flat portion is generally a heat-sealed portion, and the package is formed by tearing or cutting the package inside the end of the flat portion 4. There is an opening through which the tablet 6 can be detached from the package 2 .

Two opposite ends of the housing 1 are respectively provided with openings (not shown), the length of the opening is slightly larger than the width of the package 2 , and the height of the opening is larger than the flat portion 4 . The thickness is smaller than the thickness of the bulging portion 5. When the package 2 is placed in the housing 1, the flat portions 4 at both ends of the package 2 in the longitudinal direction extend from the openings at both ends of the housing 1. come out.

The pharmaceutical tablet 6 of the present invention is sealed and packaged by the package 2 when leaving the factory, so there will be no volatilization and leakage of the pharmaceutical tablet 6, oxidation and deterioration of the pharmaceutical, etc., and the stability of the pharmaceutical effect can be ensured. When leaving the factory, the package 2 can be placed in the casing 1 or outside the casing 1. When in use, the user can place the packing 2 in the casing 1, preferably when the package is shipped from the factory. The object 2 is placed in the housing 1, which is convenient for the user to operate and has better user friendliness. When the package 2 covered with the pharmaceutical tablet 6 is placed in the housing 1, the flat portions 4 at both ends in the longitudinal direction extend from the openings at both ends of the housing 1, and one end of the extended package 2 is torn off. Open or cut to form an opening, and pull the other end. Since the vertical height of the opening is greater than the thickness of the flat portion 4 and less than the thickness of the bulging portion 5, the opening can only allow the flat portion 4 of the package to be opened. Therefore, as the other end of the package 2 is pulled, the drug tablet 6 moves relative to the opening side of the package under the blocking of the opening, and is finally torn from one end of the package. It slides out through the opening formed by opening or cutting and remains inside the casing 1 . The whole process does not need to touch the tablet, so it is convenient to use, healthy and pollution-free.

In Figure 1-5, the casing 1 is composed of an upper casing 1-1 and a lower casing 1-2. The upper and lower casings are connected by a detachable structure, for example, the upper and lower casings are detachably connected by a clamping structure. , which is convenient for production and assembly.

In addition, the casing can also adopt an integrally formed casing structure, and the casing is provided with an opening for placing the packaged objects. The method for placing the packaged objects in the shell is not limited here, as long as the packaged objects can be put into the shell. to the inside of the housing. Preferably, the upper and lower casings are connected through a detachable structure, which facilitates assembly and production, and also facilitates the user to open the casing to place pharmaceutical tablets. When leaving the factory, the package covered with the tablet is placed between the upper and lower shells. The user only needs to tear one end of the package 2 and pull the other end to place the tablet 6 on the shell without contact. internal. When the service life of the tablet 6 is up, the upper and lower casings can be opened, and the new package 2 can be placed in it, so that the casing 1 can be reused and the service life of the product can be increased. For the method of forming the end opening of the casing, when using the upper and lower casings, only a concave part needs to be formed at the end edge of one casing. Provided, when the upper and lower housings are joined together, a tiny opening or gap can be formed at the end. In addition, the upper and lower casings can also be fixedly connected in a non-removable manner, and the package is put into it before the fixed connection.

An incision or cutting indication mark is provided on the flat portion 4 at one end extending out of the casing in the length direction of the package 2, and a pulling indication mark, such as an indication arrow, is provided on the flat portion 4 at the other end, and the other end is provided with a non-slip pattern. By providing a slit 7 or a cutting indication mark (not shown) on the flat part of one end extending out of the casing in the length direction of the package 2, it is convenient for the user to tear the package along the slit to form an opening, or to cut the package along the cutting indication mark. objects form openings. The other end is provided with a pulling indication mark 8, such as an indication arrow, to facilitate the user to identify the pulling direction. Prevent slippage when pulling the package by setting the anti-skid pattern.

The use of the insect repellent device is as follows: first, the package 2 covered with the pharmaceutical tablet 6 is placed in the housing, and the flat parts 4 at both ends of the package 2 in the length direction extend from the openings at both ends of the housing 1, and the extension One end of the outgoing package 2 is torn or cut to form an opening, and the other end is pulled. Since the vertical height of the opening is greater than the thickness of the flat portion 4 and less than the thickness of the bulging portion 5, the opening is Only the flat part 4 of the package can pass through, but the coated tablet 6 cannot pass. Therefore, as the other end of the package 2 is pulled, the package is gradually pulled out of the housing, and the tablet 6 is blocked by the opening. The downward movement is relative to the opening side of the package, and finally slides out from the opening formed by tearing or cutting one end of the package and remains inside the casing 1 . The whole process does not need to touch the tablet, so it is convenient to use, healthy and pollution-free. After the medicinal tablet is detached from the package, the insect repellent gas is produced and emitted from the through hole of the casing, thereby forming an insect repellent effect in a certain space.

The specific embodiments in the present invention are only examples of preferred implementations, and are not intended to limit the scope of implementation of the present invention. Equivalent changes and modifications made according to the content of the present invention shall be regarded as the protection scope of the present invention.
