- the present invention relates to a complex cap, and more particularly to a complex cap for use with a culture container assembly.
- Plant tissue culture is a technique used to propagate plants under sterile conditions. Plant tissue culture is widely used in horticulture, agriculture, forestry, and so on. By the plant tissue culture, plants are propagated in sterile containers that allow them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens. Generally, the culture containers have great influences on the growth rates, the success or failure, and/or the healthy conditions of the plants. For providing environments suitable to propagate plants, the culture container should have some characteristics such as gas permeability, light transmittance, controllable relative humidity, anti-pollutant property and the like. Among these characteristics, gas permeability and relative humidity are two of the most factors that influence the morphology, quality and the survival rate of seedling.
- the culture container is often covered by a low gas-permeable article such as an aluminum foil paper or a rubber plug.
- the relative humidity in the culture container is excessively increased and thus causes hindrance from growing the plants.
- the growth hindrance includes for example the lack of waxy surface or malfunction of gas pores.
- the excess increase of the relative humidity causes accumulation of harmful gases such as ethylene gas or phenolic components, so that the physiology and the morphology of the seedling are both abnormal.
- the excess increase of the relative humidity causes low acclimatization survival rate or extended acclimatization period. Therefore, the yield is reduced and fabricating cost is increased.
- the culture container includes a bottle body and a sealing cap.
- An example of the sealing cap includes but is not limited to an aluminum foil paper, a rubber plug or a silicone plug.
- FIG. 1 is a schematic cross-sectional view of a conventional culture container.
- the conventional culture container 10 comprises a bottle body 11 and a sealing cap 12 .
- the sealing cap 12 is an elastomeric component such as a rubber plug or a silicone plug.
- the sealing cap 12 is detachably plugged in the bottle mouth of the bottle body 11 for sealing the bottle mouth.
- the sealing cap 12 has a central gas-permeable hole 121 .
- gases are permissible to permeate into or out of the inner portion of the bottle body through the gas-permeable hole 121 .
- some cotton is inserted into the gas-permeable hole 121 .
- the periphery of the bottle mouth and the top surface of the sealing cap 12 are often covered with a layer of aluminum foil paper 13 or a plastic cover (not shown).
- the conventional culture container 10 has the advantage of cost-effectiveness, there are still some drawbacks.
- the sealing cap 12 needs to be replaced by a new one during different propagation stages of the plants, the replacing procedure needs to be implemented on a sterile operating platform in order to prevent from being contaminated.
- the sealing cap 12 and the aluminum foil paper 13 may obstruct the ambient light from entering the inner portion of the bottle body, which is detrimental to growth of plants. It is found that too small amount of cotton 122 fails to effectively obstruct external contaminants. Whereas, too large amount of cotton 122 results in poor gas permeability and thus high relative humidity. Under this circumstance, the gas permeability and the high relative humidity fail to be precisely adjusted according to the propagation stages of the plants.
- the sealing cap may obstruct the ambient light, and it is difficult to adjust the gas permeability and the high relative humidity within the bottle body.

- the coupling element has a first coupling part to be coupled with the neck portion of the bottle body, a recess formed in the first coupling part, and a first opening is formed in a bottom of the recess. The first opening is communicated with the mouth portion of the bottle body when the first coupling part is coupled with the neck portion of the bottle body.

Description
- The present invention relates to a complex cap, and more particularly to a complex cap for use with a culture container assembly.
- Plant tissue culture is a technique used to propagate plants under sterile conditions. Plant tissue culture is widely used in horticulture, agriculture, forestry, and so on. By the plant tissue culture, plants are propagated in sterile containers that allow them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens. Generally, the culture containers have great influences on the growth rates, the success or failure, and/or the healthy conditions of the plants. For providing environments suitable to propagate plants, the culture container should have some characteristics such as gas permeability, light transmittance, controllable relative humidity, anti-pollutant property and the like. Among these characteristics, gas permeability and relative humidity are two of the most factors that influence the morphology, quality and the survival rate of seedling.
- During propagation of plants in the culture container, the culture container is often covered by a low gas-permeable article such as an aluminum foil paper or a rubber plug. In such circumstance, the relative humidity in the culture container is excessively increased and thus causes hindrance from growing the plants. For example, the growth hindrance includes for example the lack of waxy surface or malfunction of gas pores. In addition, the excess increase of the relative humidity causes accumulation of harmful gases such as ethylene gas or phenolic components, so that the physiology and the morphology of the seedling are both abnormal. Moreover, if the culture container is covered by the low gas-permeable article during the in vitro acclimatization, the excess increase of the relative humidity causes low acclimatization survival rate or extended acclimatization period. Therefore, the yield is reduced and fabricating cost is increased.
- Usually, the culture container includes a bottle body and a sealing cap. An example of the sealing cap includes but is not limited to an aluminum foil paper, a rubber plug or a silicone plug.
FIG. 1 is a schematic cross-sectional view of a conventional culture container. As shown inFIG. 1 , theconventional culture container 10 comprises abottle body 11 and a sealingcap 12. The sealingcap 12 is an elastomeric component such as a rubber plug or a silicone plug. The sealingcap 12 is detachably plugged in the bottle mouth of thebottle body 11 for sealing the bottle mouth. The sealingcap 12 has a central gas-permeable hole 121. When the sealingcap 12 is plugged in the bottle mouth of thebottle body 11, gases are permissible to permeate into or out of the inner portion of the bottle body through the gas-permeable hole 121. For preventing external contaminants such as bacteria of spores from entering the inner portion of the bottle body, some cotton is inserted into the gas-permeable hole 121. For facilitating isolation from the external contaminants, the periphery of the bottle mouth and the top surface of the sealingcap 12 are often covered with a layer ofaluminum foil paper 13 or a plastic cover (not shown). - Although the
conventional culture container 10 has the advantage of cost-effectiveness, there are still some drawbacks. For example, if the sealingcap 12 needs to be replaced by a new one during different propagation stages of the plants, the replacing procedure needs to be implemented on a sterile operating platform in order to prevent from being contaminated. In addition, thesealing cap 12 and thealuminum foil paper 13 may obstruct the ambient light from entering the inner portion of the bottle body, which is detrimental to growth of plants. It is found that too small amount ofcotton 122 fails to effectively obstruct external contaminants. Whereas, too large amount ofcotton 122 results in poor gas permeability and thus high relative humidity. Under this circumstance, the gas permeability and the high relative humidity fail to be precisely adjusted according to the propagation stages of the plants. - Therefore, there is a need of providing a complex cap for use with a culture container assembly to obviate the drawbacks encountered from the prior art.
- As previously described in the prior art, the procedure of replacing the sealing cap needs to be implemented on a sterile operating platform, the sealing cap may obstruct the ambient light, and it is difficult to adjust the gas permeability and the high relative humidity within the bottle body. For obviating the drawbacks encountered from the prior art, the present invention provides a complex cap for use with a culture container assembly.
- In accordance with an aspect of the present invention, there is provided a complex cap for use with a bottle body having a mouth portion and a neck portion. The complex cap includes a coupling element, a shielding element and at least one filtering element. The coupling element has a first coupling part to be coupled with the neck portion of the bottle body, a recess formed in the first coupling part, and a first opening is formed in a bottom of the recess. The first opening is communicated with the mouth portion of the bottle body when the first coupling part is coupled with the neck portion of the bottle body. The shielding element is used for at least partially sheltering the first opening of the coupling element and comprises a second coupling part to be tight-fitted into the recess of the coupling element. The filtering element is mounted in the recess of the coupling element and arranged between the coupling element and the shielding element for filtering off external contaminants and controlling gas-permeable amount.

Consequently, thesecond coupling part 2031 is tight-fitted into therecess 2012 of thecoupling element 201 to fix thefirst shielding element 203 onto thecoupling element 201. - In some embodiments, an engaging
rib 2032 is formed on the outer periphery of thesecond coupling part 2031 of thefirst shielding element 203. When thesecond coupling part 2031 is inserted into therecess 2012 of thecoupling element 201, the engagingrib 2032 is engaged with the engaginggroove 2016 so as to avoid detachment of thesecond coupling part 2031 from therecess 2012 and facilitate securely fixing thefirst shielding element 203 onto thecoupling element 201. Furthermore, thefirst shielding element 203 has asecond extension part 2033. Thesecond extension part 2033 is externally extended from the top edge of thesecond coupling part 2031. The diameter of thesecond extension part 2033 is greater than that of thecoupling element 201, so that a portion of thesecond extension part 2033 is extended outside thecoupling element 201 after thefirst shielding element 203 is fixed onto thecoupling element 201. For replacing thefirst shielding element 203 with a new one, the user may exert a pulling force on thesecond extension part 2033 to withdraw thefirst shielding element 203 from thecoupling element 201 without difficulty. - Furthermore, a
second opening 2034 is formed in the center of thesecond coupling part 2031 of thefirst shielding element 203. Via thesecond opening 2034, the gases inside and outside thebottle body 21 are exchangeable. Thesecond coupling part 2031 hasseveral ribs 2035, which are formed in thesecond opening 2034, radially arranged with respect to the centerline of thesecond opening 2034 and connected to the inner surface of thesecond coupling part 2031. -
FIG. 2F is a schematic front perspective view of the second shielding element shown inFIG. 2A .FIG. 2G is a schematic upside-down perspective view of the second shielding element inFIG. 2A .FIG. 2H is an upside-down plan view of the second shielding element shown inFIG. 2A . Thesecond shielding element 204 comprises asecond coupling part 2041, an engagingrib 2042, asecond extension part 2043, one or moresecond openings 2044 andseveral ribs 2045. For example, thesecond shielding element 204 comprises one or twosecond openings 2044. The functions of thesecond coupling part 2041, the engagingrib 2042 andsecond extension part 2043 included in thesecond shielding element 204 ofFIGS. 2F and 2G are similar to those shown inFIGS. 2D and 2E , and are not redundantly described herein. In addition, thesecond opening 2044 of thesecond shielding element 204 is distinguished from thesecond opening 2034 of thefirst shielding element 203 in the size. Thesecond opening 2034 of thefirst shielding element 203 has a relatively larger size that allows for a relatively larger gas-exchangeable amount. Thesecond opening 2044 of thesecond shielding element 204 is relatively smaller that allows for a relatively smaller gas-exchangeable amount. Due to the different gas-exchangeable amounts, thesecond shielding elements second opening 2044 of thesecond shielding element 204 may be used in the high-pressure sterilization stage for adjusting the gas-exchangeable amount of theculture container assembly 2. In some embodiments, thesecond coupling part 2041 has athird opening 2046 in the bottom of thereof. Thesecond coupling part 2041 hasseveral ribs 2035, which are formed in thethird opening 2046, radially arranged with respect to the centerline of thethird opening 2046 and connected to the inner surface of thesecond coupling part 2041. - Please refer to
FIG. 2A again. Thefiltering element 202 is mounted in thecoupling element 201 for filtering off external contaminants, controlling gas-permeable amount and adjusting relative humidity inside thebottle body 21. Thefiltering element 202 is mounted in therecess 2012 of thecoupling element 201. When one of thefirst shielding element 203 and thesecond shielding element 204, thefiltering element 202 is arranged between thecoupling element 201 and thefirst shielding element 203 or thesecond shielding element 204 and sustained against theribs 2015 of thecoupling element 201 and theribs 2035 of thefirst shielding element 203 or theribs 2045 of thesecond shielding element 204. As a consequence, thefiltering element 202 is clamped within therecess 2012 and between theribs 2015 and theribs - In some embodiment, the
coupling element 201 is made of elastomeric material such as rubber, and thefirst shielding element 203 and thesecond shielding element 204 are made of transparent or opaque hard material such as plastic material. Thefiltering element 202 may have a single-layered or multi-layered structure. In addition, thefiltering element 202 has controllable gas permeability, high light transmittance, controllable water vapor permeability and anti-pollutant property, thereby filtering off external contaminants, controlling gas-permeable amount and adjusting relative humidity inside thebottle body 21. In some embodiment, two ormore filtering elements 202 are mounted in therecess 2012 of thecoupling element 201. It is preferred that thefiltering elements 202 are made of non-woven fabric, paper, membrane, tiny gauze or a combination thereof. - Hereinafter, a process of assembling the
culture container assembly 2 will be illustrated as follows with reference toFIG. 2A as well asFIGS. 3A˜3D . First of all, thefirst coupling part 2011 of thecoupling element 201 is coupled with theneck portion 211 of thebottle body 21. At the same moment, thefirst extension part 2014 is sheathed around theneck portion 211 of thebottle body 21 so as to facilitate tightly coupling thecoupling element 201 with theneck portion 211 of thebottle body 21. As shown inFIG. 3A , thecoupling element 201 is fixed onto thebottle body 21 and therecess 2012 of thecoupling element 201 is partially received in thebottle body 21 through themouth portion 212 such that thefirst opening 2013 is communicated with the inner portion of thebottle body 21. Next, at least onefiltering element 202 is inserted into therecess 2012 of thecoupling element 201, in which thefiltering element 202 is in close contact with theribs 2015 formed in thefirst opening 2013 of thecoupling element 201. Meanwhile, as shown inFIG. 3B , thefirst opening 2013 of thecoupling element 20 is partially shielded by thefiltering element 202, thereby filtering off external contaminants, controlling gas-permeable amount and adjusting relative humidity inside thebottle body 21. Next, according to the requirements of gas-exchangeable amount, relative humidity and pressure within thebottle body 21 at different propagation stages of the plants, thefirst shielding element 203 or thesecond shielding element 204 is selectively used. For example, in a case that a relatively higher gas-permeable amount is needed for propagating the plant tissues, thesecond coupling part 2031 of thefirst shielding element 203 is tight-fitted into therecess 2012 of thecoupling element 201 and theengaging rib 2032 of thesecond coupling part 2031 is engaged with the engaginggroove 2016 in the sidewall of therecess 2012. Meanwhile, theribs 2035 of thefirst shielding element 203 are sustained against thefiltering element 202 such that thefiltering element 202 is clamped within therecess 2012 and between theribs 2015 and theribs 2035, as is shown inFIG. 3C . Whereas, in another case that a relatively lower gas-permeable amount is needed in the sterilization stage, thefirst shielding element 203 is detached from thecoupling element 201 and then thesecond coupling part 2041 of thesecond shielding element 204 is tight-fitted into therecess 2012 of thecoupling element 201, as is shown inFIG. 3D . The means of connecting thesecond shielding element 204 with thecoupling element 201 is similar to that of connecting thefirst shielding element 203 with thecoupling element 201, and will not be redundantly described herein. Due to a relatively smaller-sizedsecond opening 2044 of thesecond shielding element 204, thesecond shielding element 204 may be used in the sterilization stage for adjusting the gas-exchangeable amount of theculture container assembly 2. - The size, the shape and the number of the
second opening 2034 of thefirst shielding element 203 or thesecond opening 2044 of thesecond shielding element 204 may be modified according to the requirements of gas-exchangeable amount, relative humidity and pressure within thebottle body 21 at different propagation stages of the plants. - From the above description, the complex cap of the present invention is fabricated by assembling a coupling element, at least one shielding element and at least one filtering element. By selecting proper shielding elements in different propagation stages of the plants, the gas permeability and the relative humidity within the bottle body are adjustable so as to increase the acclimatization survival rate, reduce the acclimatization period, and enhance the quality and the survival rate of plantlet. Since the shielding elements with different sizes of second openings are used to comply with different propagation stages, proper gas-exchangeable amount and relative humidity are achieved. In addition, the filtering element is effective for filtering off external contaminants, controlling gas-permeable amount and adjusting relative humidity inside the bottle body.
- While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
