Description
- This invention relates to sealing mechanisms for a vessel, particularly seals for vessels which can preserve products having several raw materials, a refreshing drink for example, in a single vessel by isolating the raw materials from each other until they are mixed when ready to be used. The invention also relates to methods to seal the vessel.
- The quality of a medicine which is used by mixing two agents, and/or a refreshing drink which is produced by mixing a raw material into a liquid or the like, may change when they are not used or consumed for a long time after they were mixed, because the mixed agents react or the raw material mixed into the liquid deteriorates under the influence of sunlight or oxygen in the air. Therefore, as a way to preserve these liquids or the like in a condition where the original qualities are kept, a proposed method involves providing a receiving chamber for a raw material in a cap that seals the vessel including the liquid inside so that the raw material and the liquid to be mixed are isolated and preserved until required. One known sealing mechanism for a vessel with a cap closure is disclosed in JP 2004-75133 (called "the first prior art" below).
- This sealing mechanism of the first prior art comprises a cap and a vessel having an opening portion, and is characterised by a structure of the cap. Namely, the cap used in the sealing mechanism has a plug portion having a top wall to cover the vessel, which fits on an outer circumferential surface of the opening portion by an inner surface of a side wall projecting from the top wall along a central axis. A receiving chamber is formed by a cylindrical wall projecting from the top wall in the side wall of the plug portion, a seal plug to seal the receiving chamber is arranged to be separate from the cylindrical wall by a sleeve loosely fitting on the cylindrical wall. In the case of the sleeve, it is prevented from being pulled out from the vessel by a flexible projecting portion having an outer diameter larger than an inner diameter of the opening portion. Also the projecting portion has flexibility to allow to pass the inner diameter by bending and subsequently resist backward movement. Thus, it can be inserted inside the vessel easily but can not be pulled out from the vessel after insertion.
- As other means to form the receiving chamber for materials in the cap of the vessel, there are bottle caps disclosed in JP 2003-2350 (called "the second prior art" below) or Japanese utility model publication No. S44-12957, S50-18846 (called "the third prior art" below).
- The bottle cap of the second prior art comprises a first portion to be fixed and a removable second portion separably screwed and coupled to the first portion. Further, the first portion has an axial through hole and the removable portion has an inner plug portion which extends through the hole. The inner plug portion opens when the removable portion moves in relation to the first portion fixed to the vessel, and the material charged and sealed in the receiving chamber of the inner plug portion is arranged to spout by pressurised gas.
- In the case of the bottle cap of the third prior means, a receiving chamber formed in a cap is arranged to be sealed by an inner cap. Here, the inner cap has a bottom plate which is larger in diameter than an inner diameter of an opening portion of a vessel and which has a flexible rim portion. The rim portion of the bottom of the bottom plate is shaped to hardly bend downward when in a settled condition. When the cap seals the vessel, the rim portion of the bottom plate of the inner cap inserted with the receiving chamber into the opening portion bends upwardly and shrinks, but as it passes the opening portion and reaches an extended wide portion of the vessel it returns to its original state and is fixed. When the vessel is opened, the cap moves upwardly, and the inner cap is held inside the vessel as the rim portion of the bottom plate engages the inner surface of the opening portion and is held there. The inner cap then drops off the receiving chamber and the receiving chamber is opened.
- However, in both cases of the first and second prior arts described above, before the receiving chamber is sealed by the seal plug, some member to open the receiving chamber, namely the first portion or the sleeve, has to be positioned around the receiving chamber and a space is formed between the receiving chamber and the member to open the receiving chamber. Then, in the situation where the cap containing the material dropped and remained in the space is fixed on the vessel, there is a problem bacteria are generated in the space as the liquid flows in the space. Further, because the space between the receiving chamber and the member to open the receiving chamber is narrow, it is extremely difficult to clear any material that drops into the space.
- In the case of the third prior art, any member is not positioned around the receiving chamber. However, its structure has to be arranged to suit the shape of the vessel. In cases where the opening portion of the vessel is extremely long or short, the third prior art is rarely used. Further, in the case where the rim portion of the bottom plate of the inner cap is made to bend downward too much by production error or other reasons, the inner cap will not engage the opening portion as it moves upwardly with the cap as the vessel is opened and the cap plugs the vessel without dropping from the opening portion.
- Therefore, the present invention aims to provide sealing mechanisms and methods more favourable to provide a receiving chamber for a raw material in a cap that seals a vessel containing a liquid inside so that the raw material and the liquid to be mixed are isolated and preserved. Namely, such mechanisms and methods enable the sealed receiving chamber to be smoothly opened without positioning any member around it, can be applied regardless of the shape of the vessel, and releases the material stored in the receiving chamber more reliably without plugging the vessel.
- The first sealing mechanism relating to the present invention is for a vessel which can be closed by a cap, and has a sleeve.
- The vessel has an opening portion and the cap has a plug portion and a seal plug. The plug portion has a top wall to cover the opening portion of the vessel, a side wall and a cylindrical wall respectively projects from the top wall along an axis of the plug portion. The side wall has an inner circumferential surface arranged to fit on an outer circumferential surface of the opening portion. The cylindrical wall is inside of the side wall and forms a receiving chamber having an opening at its lower end face. The seal plug closes the opening by being fixed to the cylindrical wall and has an outer circumferential portion projecting from an outer circumferential surface of the cylindrical wall.
- The sleeve is arranged to be fixed to the opening portion of the vessel and has an protruding portion on an inner surface of a through hole.
- The outer circumferential portion of the seal plug is allowed to pass the protruding portion in direction for insertion but not for pulling off.
- In such a sealing mechanism, because the outer circumferential portion of the seal plug is allowed to pass the protruding portion in direction for insertion, the cylindrical wall can be inserted into the sleeve after sealing the receiving chamber by seal plug. Further, because the outer circumferential portion of the seal plug is not allowed to pass the protruding portion in direction for pulling off, the seal plug drops off the cylindrical wall by function of the outer circumferential portion and the protruding portion as the cap moves in direction where its cylindrical wall is to be pulled off the sleeve. Therefore, it is possible to make sealing receiving chamber smoothly opens without positioning the sleeve around the receiving chamber.
- Further, because the protruding portion is formed on the sleeve to be fixed to the vessel, this mechanism can be applied regardless of the shape of the vessel by arranging the sleeve in suitable shape.
- Furthermore, by using the protruding portion, the sleeve is prevented from plugging with the seal plug and the material stored in the receiving chamber can be released at high reliability without plugging the vessel.
- The sleeve may have a flange portion arranged to fit on a top surface of the opening portion on an end portion.
- In this case, the sleeve can be easily fixed to the vessel by welding or other method using the flange.
- The second sealing mechanism relating to the present invention is for a vessel which can be closed by a cap.
- The vessel is a set of an opening portion and a storage portion. The cap has a plug portion and a seal plug. The plug portion has a top wall to cover the opening portion of the vessel, a side wall and a cylindrical wall respectively projects from the top wall along an axis of the plug portion. The side wall has an inner circumferential surface arranged to fit on an outer circumferential surface of the opening portion. The cylindrical wall is inside of the side wall and forms a receiving chamber having an opening at its lower end face. The seal plug closes the opening by being fixed to the cylindrical wall and has an outer circumferential portion projecting from an outer circumferential surface of the cylindrical wall.
- The opening portion has a protruding portion on its inner surface. The outer circumferential portion of the seal plug is allowed to pass the protruding portion in direction for insertion but not for pulling off.
- In such a sealing mechanism, because the outer circumferential portion of the seal plug is allowed to pass the protruding portion in direction for insertion, the cylindrical wall can be inserted into the opening portion of the vessel after sealing the receiving chamber by seal plug. Further, because the outer circumferential portion of the seal plug is not allowed to pass the protruding portion in direction for pulling off, the seal plug drops off the cylindrical wall by function of the outer circumferential portion and the protruding portion as the cap moves in direction where its cylindrical wall is to be pulled off the opening portion. Therefore, it is possible to make sealed receiving chamber smoothly opens without positioning any member around the receiving chamber.
- Further, because of being a set of the opening portion and the storage portion, out of which set only the opening portion being required to be shaped specially to this mechanism, the vessel keeps to have common shape in the storage portion and can be used in general purpose. Therefore, this mechanism can be applied without strongly influenced by the shape of such the vessel that is not special but can be used in general purpose to some extent.
- Furthermore, by using the protruding portion, the material stored in the receiving chamber can be released at high reliability without plugging the vessel with the seal plug.
- The flanges arranged to be suite each other may be formed on joint portions connect the opening portion and the storage portion.
- In this case, the opening portion and the storage portion can be easily connected by welding or other method using the flanges.
- The first method relating to the present invention use members construct aforesaid first sealing mechanism, namely, the vessel, the cap and the sleeve with the protruding portion arranged to allow the seal plug passing in direction for insertion but not for pulling off. Then the method comprises fixing the sleeve on the opening portion of the vessel, charging a first material in the vessel, and closing the vessel by the cap charged with a second material in its receiving chamber and already sealed with the seal plug.
- In such method, a step of positioning the sleeve around the cylindrical wall, namely a step of inserting the cylindrical wall into the sleeve, comes after a step of charging the material into the receiving chamber. Further, because the protruding portion of the sleeve is arranged to allow the seal plug passing in direction for insertion but not for pulling off, the seal plug drops off the cylindrical wall by function of the outer circumferential portion and the protruding portion as the cap moves in direction where its cylindrical wall is to be pulled off the opening portion after sealing the vessel. Therefore, it is possible to make sealed receiving chamber smoothly opens without positioning any member around the receiving chamber. Further, the material dropped around the receiving chamber during charging step can be removed easily and the space between the cap and the sleeve is prevented from bacteria being generated.
- The second method relating to the present invention use the members construct aforesaid second sealing mechanism, namely, the cap and the vessel with the protruding portion formed on the inner surface of the opening portion and arranged to allow the seal plug passing in direction for insertion but not for pulling off. Then the method comprises constructing the vessel by connecting the opening portion and the storage portion, charging a first material in the vessel, and closing the vessel by the cap charged with a second material in its receiving chamber and already sealed with said seal plug.
- In such method, because the protruding portion is formed on the inner surface of the opening portion and arranged to allow the seal plug passing in direction for insertion but not for pulling off, and the sealing mechanism using such the vessel that having function to open the seal plug is applied, it is possible to make sealed receiving chamber smoothly opens dispensing with a step of positioning some member around the receiving chamber.

- Figs. 1 and 2 show a first embodiment of a sealing mechanism in accordance with the present invention. Fig. 1 is a sectional elevation showing the vessel, the cap and the sleeve of the sealing mechanism in a condition where the vessel is opened. Fig. 2 shows the functioning states of the sealing mechanism, Fig. 2(a) being a sectional elevation showing the condition before the receiving chamber is opened and Fig. 2(b) being a sectional elevation showing the condition after the receiving chamber is opened.
- The sealing mechanism is for a
vessel 2 which can be closed by acap 1 and has asleeve 6. - The
vessel 2 has anopening portion 3 and thecap 1 has aplug portion 4 and aseal plug 5. Theplug portion 4 has atop wall 11 to cover theopening portion 3 of thevessel 2. A side wall 12 and an inwardly disposedcylindrical wall 15 respectively project from thetop wall 11 along an axis X of theplug portion 4. The side wall 12 has an inner circumferential surface arranged to fit by screwing on an outer circumferential surface of theopening portion 3. Thecylindrical wall 15 is positioned inside of the side wall 12 and forms a receivingchamber 14 having anopening 13 at its lower end face. Theseal plug 5 closes theopening 13 by being fixed to thecylindrical wall 15 and has an outercircumferential portion 16 projecting from an outer circumferential surface of thecylindrical wall 15. - The
sleeve 6 is arranged to be fixed to theopening portion 3 of thevessel 2. The sleeve has ahole 21 and an inwardly directed tip or protrudingportion 22 at its lower end. - The outer
circumferential portion 16 of theseal plug 5 is allowed to pass the protrudingportion 22 when inserted into the vessel, but not when the cap is removed. - In such a sealing mechanism, because the outer
circumferential portion 16 of theseal plug 5 is allowed to pass the protrudingportion 22 in the direction of insertion, thecylindrical wall 15 can be inserted into thesleeve 6 after the receivingchamber 14 is sealed byseal plug 5. Further, because the outercircumferential portion 16 of theseal plug 5 is not allowed to pass the protrudingportion 22 in the direction of removal, theseal plug 5 drops off thecylindrical wall 15 by function of the outercircumferential portion 16 and the protrudingportion 22 as thecap 1 moves in the direction where thecylindrical wall 15 is to be removed from thesleeve 6. Therefore, it is possible to make the sealed receivingchamber 14 smoothly open without positioning any members around the receivingchamber 14. - Further, because the protruding
portion 22 is formed on thesleeve 6 to be fixed to thevessel 2, this mechanism can be applied regardless of the shape of thevessel 2 by arranging thesleeve 6 to have the appropriate shape. - Furthermore, by using the protruding
portion 22, thesleeve 6 is prevented from being plugged by theseal plug 5 and the material 32 stored in the receivingchamber 14 can be released more reliably without plugging thevessel 2. - The
sleeve 6 has aflange portion 23 at its upper end. The flange locates on a top surface of theopening portion 3. - In this Figure, the
sleeve 6 can be easily fixed to thevessel 2 by welding or other fixing methods using theflange 23. - On the lower side of the
top wall 11, a packing 33 is attached. - In Figure 1, the
vessel 2 can be sealed tightly. - The lower portion of the side wall 12 carries a cut-
ring 34 which is connected thereto by a connectingportion 35. - With reference to Figure 2a, as the
cap 1 is screwed on, to seal thevessel 2, the cut-ring 34 engages thevessel 2 as showed in Fig. 2(a), and cannot be opened without breaking the connectingportion 35. Therefore, thecap 1 is prevented from being opened improperly by a third party while the sealed vessel is being distributed. - The first sealing method relating to the present invention can be put into practice by using the
vessel 2, thecap 1 and thesleeve 6 with the protrudingportion 22 is arranged to allow theseal plug 5 to pass in the direction of insertion but not in the direction of pulling off. - An embodiment of the first sealing method which relates to the present invention is explained below referring to Figs. 3 and 4. Fig. 3 shows a step of charging a first material into the vessel. Fig. 3(a) is a sectional elevation showing the condition before the sleeve is fixed to the vessel and Fig. 3(b) is a sectional elevation showing the condition where the first material is being charged into the vessel. Fig. 4 shows a step of charging a second material into the cap. Fig. 4(a) is a sectional elevation showing the condition where the second material is being charged into the cap, Fig. 4(b) is a sectional elevation showing the condition where the receiving chamber is sealed by the seal plug and Fig. 4(c) is a sectional elevation showing the condition where excess of the second material located around the receiving
chamber 14 is being removed. - With reference to Figure 3(a), initially the
sleeve 6 is inserted into theopening portion 3 of thevessel 2. Next, theflange 23 is welded to the top surface of theopening portion 3 by pressing and heating, and consequently thesleeve 6 is fixed to theopening portion 3 of thevessel 2. Then as shown in Fig. 3(b), thefirst material 31 is charged into thevessel 2. In this sealing method, though thefirst material 31 is a liquid, the form of the first material is not limited to a liquid and a powder or a solid also may be charged into thevessel 2. - With reference to Figure 4, a
second material 32 is charged into the receivingchamber 14 of thecap 1. Namely, thesecond material 32 is charged into the receivingchamber 14 opening (Fig. 4(a)), and theopening 13 of the receivingchamber 14 is sealed with the seal plug 5 (Fig. 4(b)). Any of thesecond material 32 dropped around the receivingchamber 14 is removed by an air flow (Fig. 4(c)). In this sealing method, the order of the steps of charging the first material and of charging the second material is not limited. The steps can be carried out in any order, or both steps may be carried out in parallel if facilities or other conditions allow it. - After completion of charging both
materials cylindrical wall 15 is inserted into the throughhole 21 of thesleeve 6 until the outercircumferential portion 16 of theseal plug 5 engages to the protrudingportion 22. Then consequently thevessel 2 is sealed by thecap 1 and theseal plug 5. - In the described sealing method, the step of positioning the
sleeve 6 around thecylindrical wall 15, namely the step of inserting thecylindrical wall 15 into thesleeve 6, comes after a step of charging the material into the receivingchamber 14. Further, because the protrudingportion 22 of thesleeve 6 is arranged to allow theseal plug 5 to pass in the direction of insertion but not in the direction of pulling off, theseal plug 5 is pulled from thecylindrical wall 15 as a result of engagement of the outercircumferential portion 16 with the protrudingportion 22 as thecap 1 is moved in a direction where thecylindrical wall 15 is pulled from theopening portion 3 after sealing thevessel 2. Therefore, it is possible to make sealed receivingchamber 14 smoothly open without positioning any members around the receivingchamber 14. Further, the material which dropped around the receivingchamber 14 during the charging step can be removed easily and thus bacteria formation can be prevented in the space between thecap 1 and thesleeve 6. - In Figs. 5 and 6, an embodiment of a second sealing mechanism relating to the present invention is shown. Fig. 5 is a sectional elevation showing the vessel and the cap of the sealing mechanism in a condition where the vessel is opened. Fig. 6 shows the functioning state of the sealing mechanism, Fig. 6(a) being a sectional elevation showing its condition before the receiving chamber is opened and Fig. 6(b) being a section elevation showing the condition after the receiving chamber is opened. In this embodiment, the same symbols are used to indicate the portions which are substantially the same as in the first embodiment and the explanation thereof is omitted or simplified.
- The sealing mechanism does not have a
sleeve 6 corresponding to that of the first sealing mechanism but comprises avessel 20 having an openingportion 3 and astorage portion 7 instead of thevessel 2. Theopening portion 3 has a protrudingportion 22 on its inner surface. The outercircumferential portion 16 of theseal plug 5 is allowed to pass the protrudingportion 22 in the direction of insertion but not in the direction of removal. - In this sealing mechanism, because the outer
circumferential portion 16 of theseal plug 5 is allowed to pass the protrudingportion 22 in the direction of insertion, thecylindrical wall 15 can be inserted into theopening portion 3 of thevessel 20 after sealing the receiving chamber byseal plug 5. Further, because the outercircumferential portion 16 of theseal plug 5 is not allowed to pass the protrudingportion 22 in the direction of removal, theseal plug 5 is pulled from thecylindrical wall 15 by engagement of the outercircumferential portion 16 with the protrudingportion 22 as thecap 1 is moved in the direction where itscylindrical wall 15 is pulled from theopening portion 3. Therefore, the sealed receivingchamber 14 smoothly opens without positioning any member around the receivingchamber 14. - Since the
vessel 20 has theopening portion 3 and thestorage portion 7, (of which only theopening portion 3 is required to be shaped specially to this mechanism), thevessel 20 has a common shape of thestorage portion 7 and can be used in general purpose. Therefore, this mechanism can be applied without being influenced by the shape of thevessel 20 that is not special but can be used in general purpose to some extent. - Furthermore, by using the protruding
portion 22, the material stored in the receivingchamber 14 can be released more reliably without plugging thevessel 20 with theseal plug 5. -
Flanges opening portion 3 and thestorage portion 7. - In this case, the
opening portion 3 and thestorage portion 7 can be easily connected by a welding or other joining method using theflanges - The second sealing method relating to the present invention can be put into practice by using the
cap 1 and thevessel 20 with the protrudingportion 22 formed on the inner surface of theopening portion 3 and arranged to allow theseal plug 5 passing in the direction of insertion but not the direction of pulling off. - An embodiment of the second sealing method relating to the present invention is explained below with reference to Fig. 7. Fig. 7 shows a step of charging a first material into the vessel, Fig. 7(a) being a sectional elevation showing the condition before the opening portion is connected to the storage portion and Fig. 7(b) being a sectional elevation showing the condition where the first material is being charged into the vessel.
- Initially, the
opening portion 3 is located so that its joint portion 3a is lowermost, and it is located on a joint portion 7a of thestorage portion 7 as shown by the arrow in Fig. 7(a). Next, theflange 24 is welded to theflange 25 of thestorage portion 7 by pressing and heating, and consequently thevessel 20 is constructed by connecting theopening portion 3 and thestorage portion 7. Then as shown in Fig. 7(b), thefirst material 31 is charged into thevessel 20. - In the case of the
cap 1, asecond material 32 is charged into it in the same manner as for the aforesaid first sealing method. Then, as the last step, thecylindrical wall 15 is inserted into theopening portion 3 until the outercircumferential portion 16 of theseal plug 5 engages and passes the protrudingportion 22. Then consequently thevessel 20 is sealed by thecap 1 and theseal plug 5. - In this sealing method, because the protruding
portion 22 is formed on the inner surface of theopening portion 3 and is arranged to allow theseal plug 5 to pass in the direction of insertion but not in the direction of pulling off, and the sealing mechanism using thevessel 20 that having function to open theseal plug 5 is applied, it is possible to make sealed receivingchamber 14 smoothly open without having to position a member around the receivingchamber 14. - According to a first sealing mechanism relating to the present invention, it is possible to make a sealed receiving chamber smoothly open without positioning any member around the receiving chamber. Further, the mechanism can be applied regardless of the shape of the vessel by forming the sleeve in a suitable shape. Furthermore, by using the protruding portion, the sleeve is prevented from plugging with the seal plug and the material stored in the receiving chamber can be released more reliably without plugging the vessel.
- According to the features of
claim 2, the sleeve can be easily fixed to the vessel. - According to a second sealing mechanism relating to the present invention of
claim 4, it is possible to make sealed receiving chamber smoothly open without positioning any members around the receiving chamber.
