Description
- The present invention relates to a cup lid assembly or a drinking-cup lid assembly and, more particularly, to a cup lid assembly that provides a liquid discharge opening to be opened or closed through turning operation made on the cup lid.
- Fast food eating has been a common life style for many busy people around the world. People often find time to enjoy their fast food while they are walking or driving. However, one thing may bother them is that beverages in their cups may be splashed or spilt during walking or driving, which may smear their clothes or cars. Therefore, it is always an important issue to design a cup lid that can be easily opened for drinking as well as securely closed when not in use while the cup user is in motion.
- U.S. Pat. No. 6,010,029 entitled “Container Lid Assembly” will be discussed below as an example of the prior art. The technical contents of this patent are summed up as follows:
- The container lid assembly includes a rotary cap 10, a lid body 20, and a control device 40, wherein a drive post 13 is provided extending from the bottom of the rotary cap 10, whereas a control block 14 with a threaded bore 15 is provided extending from the bottom of the drive post 13;
- an inner thread 221 extending downward from the inner periphery of the lid body 20 is to be received by an enlarged lower portion 22 located at the top of a container body 68; besides, a liquid discharge slot 25 and a stub 26 are provided penetrating through the lid body 20, and a lug 24 is provided downward from the middle of the discharge slot 25 and stub 26; also, an annular flange 27 is provided extending from the inner bottom of the lid body 20, and a plurality of concave openings 271 is provided on the annular flange 27; and
- an upper strip 50 and a lower strip 60 are included in the control device 40 in a way that the upper strip 50 can be mounted on the top of lower strip 60 for overlapping; besides, a
locking hole 52 is provided in the middle of the upper strip 50, whereas a square locking hole 62 is correspondingly provided in the middle of the lower strip 60; also, a reducedneck 53 is provided at each of the two sides of the upper strip 50, extending outwardly thereon to form a first end portion 55 and a second end portion 56, wherein a positioning block 57 and a sealing plug 561 are further provided at the end of the first end portion 55 and the second end portion 56 respectively; in addition, a sealing gasket 58 is provided on the positioning block 57, and a press block 541 is provided upwardly from the front side of the first end portion 55 and the second end portion 56 respectively. - To operate, the rotary cap 10 can be received by and positioned on the top of the lid body 20; also, the control block 14 under the drive post 13 can firstly go into the passage 241 of the lug 24, then go through a square hole 310 of a
cushion 31, afterwards go through the hole formed by thelocking hole 52 and square locking hole 62 from a joining made by the upper strip 50 and lower strip 60, and finally go into a recess 66 of a connector 65, while a locking screw 67 will be put into the bore 650 on the connector 65 to fasten the control device 40; furthermore, the reducedneck 53 of the upper strip 50 is designed to be pushed against by the resilient force generated by the lower strip 60, and the generated force enables the press block 541 of the upper strip 50 located closely adjacent to the concave openings 271 of annular flange 27 to make a sliding movement when the rotary cap 10 is turned by the user so as to achieve the purpose of opening or closing the liquid discharge slot 25 and stub 26. - To conclude, the aforementioned patent has mainly improved two drawbacks of its prior arts. One of them is to improve the fatigue that may be caused by the spring in the prior arts, and the other is to change the way of opening the liquid discharge slot 25 by simply turning the rotary cap 10 instead of continuously pressing the liquid discharge slot 25. Nevertheless, three drawbacks remain to be unsolved in this prior invention, which will be listed as follows:
-
- 1) The members that construct the control device 40 of the patent are very complicated in structure; as a result, manufacturing procedures such as mold opening, producing, and assembling will become more troublesome, which in turn may increase the production cost and lower the efficiency of production.
- 2) The opening and closing mechanism of the liquid discharge slot 25 is operated by a resilient force generated by the lower strip 60 in a way of pushing against the upper strip 50 when both strips are joined together; therefore, the opening and closing mechanism of the liquid discharge slot 25 is operated by flexible-textured members instead of solid-textured members; as a result, the flexible-textured members may eventually result in fatigue and cause a failure in performing sealing function.
- 3) From the control device 40 of this patent, it can be judged that the upper and lower strips 50 and 60 and locking screw 67 are all made of metal. In fact, the lower strip 60 must be a sheet of metal spring to meet the requirement of good elastic strength for pushing the upper strip 50 to lean closely to the concave openings 271 for sliding movement so as to open or close the liquid discharge slot 25 and stub 26. However, shaking motion or steaming phenomenon generated by the liquid inside a liquid container may cause the metal sheet to become rusted, which is not sanitary once if the liquid contacts the rusted portion.
- Therefore, the present invention is designed to solve the afore-mentioned problems, including high manufacturing cost, low production efficiency, the failure to entirely seal the liquid discharge slot, and the sanitary problem caused by the rusted metal sheet.
- The main object of the present invention is to provide a cup lid assembly suitable for easy and fast assembling through locking and pivotal joining method, wherein a solid-textured member of the cup lid can generate a force pressing on the liquid discharge opening upon receiving a turning force made on the cup lid, allowing the liquid discharge opening to be entirely sealed.
- According to the present invention, the cup lid assembly includes a cup receiving body, a covering lid, and a driver sheet, wherein the cup receiving body is used to cover the cup brim of a cup body, and a liquid discharge opening and a vent are provided penetrating through the cup receiving body; besides, an elastic body is provided in the middle of the cup receiving body, while a push block and a halt block are separately provided, extending from the cup receiving body thereon, located at each side of an imaginary line drawing along the liquid discharge opening and the elastic body; also, the covering lid can be pivotally received by the rim of the cup receiving body and can be turned by turning operation when it is placed on the cup receiving body; besides, a drinking opening is provided penetrating through the covering lid and can be aligned with the liquid discharge opening when the cup receiving body is turned by turning operation; also, an axle is provided extending from a position corresponding to the elastic body and located at the bottom of the covering lid, and two guide portions are symmetrically provided from the axle; moreover, a releasing slot and a press-against section are provided on the guide portion, wherein the releasing slot is connected to one end of the press-against section and also forms an arch-shaped angle, whereas an actuating block is provided at the other end of the releasing block; on the other hand, a hinder block is provided at the other end of the press-against section; as to the drive sheet, an anti-liquid-flow portion and an anti-air-flow portion are provided extendedly from the drive sheet thereon, corresponding to the locations of the liquid discharge opening and the vent respectively; besides, a pivot-connecting portion is provided extending from the center of the drive sheet, to be pivotally connected to the axle as well as to be pushed by the elastic body for getting close to the covering lid.
- To operate, when the covering lid is turned clockwise, the turning force imposing on the solid-textured object of the press-against section may push the drive sheet to make a position-shift downwardly, which in turn may enable the anti-liquid-flow portion to be tightly plugged into the liquid discharge opening whereas the anti-air-flow portion to be tightly plugged into the vent; in contrast, when the covering lid is turned anticlockwise, the drive sheet will detach from the press-against section in a manner that the elastic body will press against the pivot-connecting portion of the drive sheet, allowing the drive sheet to be located on the releasing slot, which in turn may enable the anti-liquid-flow portion and the anti-air-flow portion to be detached from the liquid discharge opening and the vent respectively for liquid outflow.
- To sum up, the present invention is not only very simple in its structure but also very handy in assembling, which in turn can lower the production cost, entirely seal the liquid discharge opening, and assure a hygienic in-cup environment when the cup lid is in use because there is no metal can be touched by the liquid in the cup body of the present invention.

Also, acover receiving portion 36 is provided along the outer rim of thecup receiving body 3, whereas at least onecover joining portion 45 is formed in a way that its center is a hole, extending along the periphery of thecovering lid 4 and corresponding to thecover receiving portion 36 for pivotally joining to thecover receiving portion 36 at the rim of thecup receiving body 3, so that thecovering lid 4 can be turned when it is placed on thecup receiving body 3. In addition, adrinking opening 41 is provided penetrating through thecovering lid 4; when thecup receiving body 3 is turned by a user, thedrinking opening 41 will be at a position corresponding to the liquid discharge opening 31. Also, anaxle 42 is provided extending from the bottom of thecovering lid 4, corresponding to theelastic body 33. Taking theaxle 42 as a dividing line, twoguide portions 43 are symmetrically provided at the two sides of the line, and a releasingslot 431 and a press-againstsection 432 are located on eachguide portion 43. The releasingslot 431 is connected to the press-againstsection 432 and forms an arch-shaped angle 433, and an actuatingblock 434 is provided at the other end of the releasingslot 431 whereas ahinder block 435 is provided at the other end of the press-againstsection 432. On the other hand, an anti-liquid-flow portion 51 and an anti-air-flow portion 52 are provided extending from the drive sheet thereon, corresponding to the positions where the liquid discharge opening 31 andvent 32 are located respectively. Besides, abig plug 511 made of flexible material is sleeved on the anti-liquid-flow portion 51, wherein afirst protrusion 512 is provided on thebig plug 511 to be corresponding to thefirst recess 311, and through plugging-in made between thefirst protrusion 512 and thefirst recess 311, theliquid discharge opening 31 can be entirely sealed. Likewise, asmall plug 521 made of flexible material is sleeved on the anti-air-flow portion 52, wherein asecond protrusion 522 is provided on thesmall plug 521 to be corresponding to thesecond recess 321, and through plugging-in made between thesecond protrusion 522 and thesecond recess 321, thevent 32 can be entirely sealed. Also, a pivot-connectingportion 53 is provided extending from the middle of thedrive sheet 5, to be pivotally connected to theaxle 42 as well as to be pushed by theelastic body 33 for leaning closely to thecovering lid 4. - Next, referring to
FIG. 4A , which is a schematic diagram illustrating that the liquid discharge opening of the cup lid of the present invention is in an opening state, the cup lid assembly is shown by a side elevation view and a top view in order to obtain a best description result, in which the position of coveringlid 4 is expressed by dash-dot lines in the top-viewed diagram. As shown inFIG. 4A , when thedrive sheet 5 is located in the releasingslot 431 and its pivot-connectingportion 33 is being pushed against by theelastic body 33, the anti-liquid-flow portion 51 and the anti-air-flow portion 52 will be away from theliquid discharge opening 31 and vent 32 respectively, and thedrinking opening 41 will be aligned with theliquid discharge opening 31, ready for the liquid in thecup body 6 to flow out from theliquid discharge opening 31. - Also, referring to
FIG. 4B , which is a schematic diagram illustrating that the covering lid showed inFIG. 4A is in operation, the cup lid assembly is also shown by a side elevation view and a top view in order to obtain a best description result, in which the position of coveringlid 4 is expressed by dash-dot lines in the top-viewed diagram. As shown inFIG. 4B , when theliquid discharge opening 31 and vent 32 are to be closed for stopping liquid in the cup body (not shown) from flowing out, the coveringlid 4 can be turned clockwise. As soon as this action is made, thedrive sheet 5 located in the releasing slot 351 will be pushed against by the arch-shapedangle 433 and turned along with the coveringlid 4 until thepush block 34 reaches the side of thedrive sheet 5 for pressing against it. - As the turning operation continues, the cup lid assembly will move into another state, which is shown in
FIG. 4C , illustrating that the covering lid showed inFIG. 4B is still in a continuous operation. Similarly, the cup lid assembly is shown by a side elevation view and a top view in order to obtain a best description result, in which the position of coveringlid 4 is expressed by dash-dot lines in the top-viewed diagram. As shown inFIG. 4C , when the coveringlid 4 is continuously being turned by turning operation, thepush block 34 will push the side face ofdrive sheet 5 located in the releasingslot 431, and because the turning force is larger than the press-against force from the arch-shapedangle 433, thedrive sheet 5 will then slide into the hinder block 435 located at the press-againstsection 432 of theguide portion 43 for positioning through guidance made by the arch-shapedangle 433. Under such circumstances, thedrive sheet 5 will be located at the press-againstsection 432 that has elevation difference from its prior location at releasingslot 431. Because of the elevation difference, thedrive sheet 5 will move downward and press against theelastic body 33 in a way that theliquid discharge opening 31 and vent 32 located at thecup receiving body 3 will be entirely blocked by the anti-liquid-flow portion 51 and anti-air-flow portion 52 respectively located at the drive sheet. By so doing, the liquid in the cup body 6 (not shown) can be stopped from flowing out, and thedrinking opening 41 will withdraw from the position that corresponds to theliquid discharge opening 31. - Furthermore, referring to
FIG. 5A , which illustrates that the covering lid showed inFIG. 4C is operated in a reverse direction, the cup lid assembly is again shown by a side elevation view and a top view in order to obtain a best description result, in which the position of coveringlid 4 is expressed by dash-dot lines in the top-viewed diagram. In addition toFIG. 5A ,FIG. 5B further illustrates that the covering lid showed inFIG. 5A is still operating in a reverse direction. Also, similar toFIG. 5A , the dash-dot lines are also used for illustrating the position of coveringlid 4. As shown inFIGS. 5A and 5B , when a user's intension is to open theliquid discharge opening 31 and vent 32, the coveringlid 4 can be turned anticlockwise. Under such circumstances, thedrive sheet 5 will not move along with the coveringlid 4 because it is being pressed against by the resilience generated by theelastic body 33. In fact, thedrive sheet 5 will slide along the press-againstsection 432 ofguide portion 43 and move into the releasing slot 351 when the coveringlid 4 is turned by turning operation, so that the drive sheet can make a position shift upwardly, enabling the anti-liquid-flow portion 51 and anti-air-flow portion 52 to upwardly open theliquid discharge 31 and vent 32 (as shown inFIG. 5A ) respectively. At this moment, if the coveringlid 4 is being continuously turned, theactuation block 434 will push against thedrive sheet 5, and the resilient force generated by theelastic body 33 will impose on thedrive sheet 5, pushing it to thehinder block 35 for a stop, whereas the anti-liquid-flow portion 51 and anti-air-flow portion 52 on thedrive sheet 5 will withdraw from theliquid discharge opening 31 and vent 32 on thecup receiving body 3 respectively. By doing so, the liquid discharge opening 31 can be aligned with the drinking opening 41 (as shown inFIG. 5B ) for the liquid in the cup body 6 (not shown) to flow out. Therefore, the present invention is not only very simple in its structure but also very handy in assembling, which in turn can lower the production cost, entirely block theliquid discharge opening 31, and assure a hygienic in-cup environment when the cup lid is in use because there is no metal can be touched by the liquid in the cup body. - Finally,
FIG. 6 is a schematic diagram illustrating another aspect of the elastic body of the cup lid of the present invention. This aspect of elastic body is different from that of in the above-mentioned embodiment in thecup receiving body 3′ because there is anaccommodation slot 37′ concavely provided in an upward direction in the middle of thecup receiving body 3′. Theaccommodation slot 37′ is used to accommodate the pivot-connectingportion 53′ instead of theelastic body 33′ when thedrive sheet 5′ is having a downward motion. In addition, anelastic body 33′ such as a spring will be provided in theaxle 42 extending from the bottom of the coveringlid 4, whereas a pivot-connectingportion 53′ extending from the middle of thedrive sheet 5′ will be pivotally connected to theaxle 42. The bottom of the pivot-connectingportion 53′ is a closed end and is connected to theelastic body 33 by hook connection so that thedrive sheet 5′ can be pulled by theelastic body 33′ to get close to the coveringlid 4. Therefore, the aforementioned functions shown inFIG. 3 can be achieved as well. - The embodiments above are only intended to illustrate the present invention; they do not, however, to limit the present invention to the specific embodiments. Accordingly, various modifications and changes may be made without departing from the spirit and scope of the present invention as described in the following claims.
