Abstract
A dual-purpose sealing cap for water buckets includes a cap body, a pulling strip and a pulling tab. The cap body is coupled on an outlet of a water bucket and has a seal lid formed on the top surface and an annular cap formed on a lower side. The annular cap has a lower rim connecting to the pulling strip through a plurality of break-off links. The pulling tab is located on a distal end of the pulling strip. The sealing cap serves dual functions, and may be coupled with water bucket tightly without loosening off and provide improved hygiene.
Description
- The present invention relates to a dual-purpose sealing cap for water buckets and particularly to a dual-purpose sealing cap for drinking water buckets of drinking machines to provide a tightly sealing without breaking off and improved hygiene and allows the water bucket to be turned easily upside down and mounted onto the water drinking machine when in use.
- With people's living standard become higher, water fountains and waterdrinking machines have become increasingly popular. The water drinking machine that couples with a water bucket is especially widely used because of its convenience and hygienic benefit.
- The conventional bucket caps for water buckets are constructed in many forms.
FIG. 1 illustrates one of them that has internal screw threads to couple with the external screw threads formed on the water outlet of the water bucket. It is simple to fabricate and easy to use. However it has disadvantages, such as the water tends to spill out if the cap is loose, and dusts and dirt are prone to contaminate the drinking water through the leaking location. Moreover, the cap is often thrown away when the water bucket is opened for use. As a result, the outlet is not sealed when the bucket is recycled. The bucket often gathers dirt inside and makes cleaning difficult. -
FIG. 2 shows another conventional cap that is widely used at present. The cap covers the bucket inlet by forced packing. While it can prevent breaking off during transportation, it is difficult to open when in use. And the water bucket could be toppled if opening of the cap is not being done properly. The problems of dirt contamination and bucket cleaning mentioned above also remain unresolved.FIG. 3 depicts yet another conventional bucket cap that is sealed on the water outlet and has a pulling tap on the bottom end. The cap may be opened and removed by pulling the pulling tab along a preset shearing line around the cap. However, such a structure is difficult to mount the water bucket onto the drinking machine when the cap is removed, and water spill often happens during mounting. -
FIG. 4 illustrates still another bucket cap that has a seal surface on a seal plug and a duct to couple with the bucket outlet. When the water bucket is mounted upside down onto the water tank of the water drinking machine, a protrusive water intake duct on the water tank rams and pushes away the seal plug to allow the water in the bucket to flow through the water intake duct. While it overcomes the spilling problem mentioned above, the seal plug floats in the water after having been rammed and pushed away. It gives users the concern of water quality. - To remedy the foregoing problem, another bucket cap is introduced as shown in
FIG. 5 . It has an indented duct on the cap and a seal surface on the bottom of the duct. The seal surface is connected to an inner side of the duct through a connection rib. When in use, the seal surface is pushed open by a water tube, but is connected to the duct through the connection rib without breaking loose and floating in the water. However, such a structure requires additional machining and more complicated mold fabrication. It has a higher cost. And the cap and the bucket outlet have to be sealed through a bulged rib. - In view of the aforesaid disadvantages, the present invention aims to provide a dual-purpose sealing cap for water buckets that can seal the water outlet tightly without breaking off and offer improved hygiene and allows the water bucket to be turned easily upside down and mounted onto the water drinking machine when in use.
- The dual-purpose sealing cap according to the invention includes a cap body, a pulling strip and a pulling tab. The cap body is to seal the outlet of a water bucket and has a seal lid on the top surface and an annular cap on a lower section that has a lower rim connecting to the pulling strip through a plurality of second break-off links. The pulling tab is located on a distal end of the pulling strip.
- In another aspect, the seal lid has an annular groove formed. The bottom of the annular groove has at least one first break-off link and a connection link to connect the seal lid and the cap body. The annular cap has an annular bulged rib formed on the peripheral inner wall. Each second break-off link is bordered by apertures on two sides.
- Compared with the conventional techniques, the invention retains their advantages, and can seal the bucket outlet tightly without breaking off, provide improved hygiene and is convenient to use. It allows the water bucket to be mounted upside down on the water drinking machine and the annular cap may serve as an ordinary cap when in use.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

FIGS. 6 and 7 , the dual-purpose sealingcap 1 for water buckets according to the invention includes acap body 10, apulling strip 11 and apulling tab 12. Thecap body 10 is formed in a cap and has a lower side extended to form anannular cap 103. It has an annular bulgedrib 104 formed on an inner peripheral wall to couple tightly with anoutlet 20 of awater bucket 2 to prevent the sealingcap 1 from loosening off. Thecap body 10 has aseal lid 100 formed on the top surface that has anannular groove 101 formed on the periphery thereof. Theseal lid 100 has a break-off structure that includes at least one first break-off link 102 and aconnection link 107 on the bottom of theannular groove 101 to connect theseal lid 100 to thecap body 10. Theannular cap 103 has alower rim 105 connecting with a plurality of second break-off links 106 which are evenly spaced from one another and interposed byapertures 108. Theannular cap 103 is connected to thepulling strip 11 through the second break-off links 106. Thepulling tab 12 is located on one distal end of thepulling strip 11 to open the sealingcap 1. - Refer to
FIG. 8 for the invention used on awater drinking machine 3. Thewater bucket 2 is mounted upside down onto awater intake duct 31 of awater tank 30 of thewater drinking machine 3. Thewater intake duct 31 rams and shears the first break-offlinks 102 to flip theseal lid 100 open, and allowwater 21 in the bucket to flow through thewater intake duct 31. Theconnection link 107 still connects theseal lid 100 to thecap body 10, thus theseal lid 100 does not float in the water. - Refer to
FIGS. 9 and 10 for the invention used as an ordinary bucket cap. Pull the pullingtab 12 to tear off the second break-offlinks 106 of thecap body 10 one by one until the entire pullingstrip 11 is removed. Remove the remained sealingcap 1, water may be poured out from thewater bucket 2 a. After use is finished, the sealingcap 1 may be coupled on theoutlet 20 a as the ordinary bucket cap. When the water in the bucket is consumed, and thewater bucket 2 a is to be recycled, the sealingcap 1 may be coupled thereon continuously. Thus the interior of the bucket may be maintained in a clean condition. - In summary, the dual-purpose sealing cap of the invention may be tightly coupled with the outlet of a water bucket without loosening off, and also provide improved hygiene.
