Description
BOTTLE CAP
This invention relates to a cap, more particularly to a bottle cap.
Referring tO FIGS. 1 and 2, a conventional bottle cap 1 includes a cap seat 11 that engages a mouth 22 of a bottle 2 and that has a membrane 12 attached to a bottom end of an inner tubular wall 112, a cap 13 that has a tubular cutter body 132 extending downwardly from a top panel 131, and a sealing ring 14.
In use, the sealing ring 14 is pulled outwardly away from the top panel 131 and the cap seat 11. Referring to FIGS. 3 and 4, when the top panel 131 is pressed, the tubular cutter body 132 is moved downwardly and penetrates the membrane 12 by virtue of a cutting end 134 of a beveled bottom open end 133 of the tubular cutter body 132.
Subsequently, the membrane 12 is cut by the bottom open end 133 and hence has a cut portiOn 121. An additive disposed in a receiving space 15 can fall into the bottle 2 through a gap between the bottom open end 133 and the cut portion 121, thereby mixing the additive and a substance disposed in the bottle 2.
However, when the xnextbrane 12 is cut by the bottom open end 133, because the rrternbrane 12 is made of aluminum foil and still has a coünection portion 123 that is not cut, the cut portion 121 tends to indent upward and contact the bottom open end 133 due to residual internal stress of the membrane 12 so that the additive in the receiving space 15 (see FIG. 2) is unable to easily fall into the bottle 2. Even if half of a periphery of the membrane 12 is cut, the same phenomenon is observed.
In addition, the membrane 12 is attached to the cap seat libyan additional adhesive bonding process, thereby increasing the production cost and an incidence of contaminating the additive. When the membrane 12 is not securely attached to the cap seat 1]. or is deformed on account of heat, leakage of the additive can result.
The object of the present invention is to provide a bottle cap that can overcome the aforesaid drawbacks of
the prior art.
According to this invention, a bottle cap includes a cap seat and a cap. The cap seat has an inner tubular wall, a bottom wall closing a bottom end of the inner tubular wall and having a periphera]. connection portion that is connected to the bottom end of the inner tubular wall, and a receiving space confined by the inner tubular wall and the bottom wall. The cap is disposed within the inner tubular wall, and has a top panel proximate to a top end of the inner tubular wall and closing the receiving space, and a tubiilar cutter body extending downwardlY from a peripheral end of the top panel toward the bottom wall.
The tubular cutter body has a beveled bottom open end slanting downwardlY from a higher part to a lower part.
The bottom open end has a cutting end formed at the lower part, a pushing end formed at the higher part and diametrically opposite to the cutting end, and two opposite valleys formed at the higher part and between the cutting end and the pushing end. The bottom open end slants upwardlY from the cutting end to the valleys and downwardlY from thevalleYs 0thepuShingefld. The cap ismovabledOwflwalY front a on-cUttiflg position to a cutting position when the top panel is pressed. The pushing end pushes a part of the connection portion of the bottom wall when the cap is in the cutting position.
Other features and advantageS of the present invention will become apparent in th following detailed descriPtiOn of the preferred embodiment of this invention, with reference to the accompanying drawings, in which: FIG. 1 shows a conventional bottle cap for a bottle; FIG. 2 is a sectional elevational view of the conventional bottle cap; FIG. 3 is the same view as FIG. 2 but with a membrane of the bottle cap being cut; FIG. 4 is a sectional plan view of the conventional bottle cap; FIG. 5 is an exploded perspective view of the preferred embodiment of a bottle cap according to this invention; FIG. 6 is an exploded sectional view of the preferred embodimeflt FIG.7 is a sectional view of the preferred embodiment in an assembled state: FIG. 8 is the same view as FIG. 7 but with a tubular cutter body in a cutting positiOfl FIG. 9 is a partly enlarged view of the preferred embodiment; and FIG. 2.0 is a sectional plan vieW of the preferred eutbodiment.
ferrjflgt0G 5, 6, and 7, the preferrede00t of a bottle cap cording to the present invention is adapted to be mounted on a bottle 3 for containing a substance (e.g., a potable drink, a medicinal liquid, a cleaning liquid, or water). The bottle 3 has a mouth 33 formed with an external screw thread 332. The bottle cap includes a cap seat 4 and a cap 5.
The cap seat 4 threadedlY engages the mouth 33 and has an inner tubular wall 43, a bottom wall 44 closing a bottom end of the inner tubular wall 43 and having a peripheral connection pOrt].0n445 (see FIGS. Band 9) that is connected to the bottom end of the inner tubular wall 43, a eceiviflg space 46 confined by the inner tubular wall 43 and the bottom wall 44, and an outer tubular wall 41. Preferably, the bottom wall 44, the inner tubular wall 43, and the outer tubular wall 41 are molded as one piece from a plastic material-The eceiViflg space 46 is adapted to contain an additive, such as probioticSi a microbe, a microbial spores food, medicine, a cleaning agent, or a dietary supplement. The additive can be in a form of powders a liquid, or solid granules.
The inner tubular wall 43 has an upper tubular portion that is proximate to atOp end thereof, and that has an inner surface formed with upper and lower annular grooves 451,452, and an outer surface formed with an outer annular groove 453. The upper and lower annular grooves 451,452 are spaced apart from each other.
The outer tubular wall 41 surrounds and is spaced apart from the inner tubular wa)J. 43, and has an inwardly bending top end 42 that is connected to the inner tubular wall 43 below the upper tubular portion 45, and an internal io surface that is formed with an internal screw thread 412 for engaging the external screw thread 332 of the mouth 33. The inner and outer tubular walls 43,41 confine a space therebetWeen, which can receive the mouth 33 of the bottle 3.
is The bottom wall 44 is thick at a center thereof and is thinned graduallY from the center to a peripheral end thereof, which is adjacent to the bottom end of the inner tubular wall 43. The bottom wall 44 has a substantiallY flat top face 441, and a downwardly protruding bottom surface 442 that is opposite to the flat top face 441, that protrudes downwardly and substantia3.1Y conically at the center of the bottom wall 44, that inclines upwardly and gradually from the center of the bottom wall 44 toward the peripheral end of the bottom wall 44, and that thereafter extends substantially parallel to the flat top face 441 when approaching the peripheral end of the bottom wall it should be noted that the bottom wall 44 could have a uniform thickness in other embodiments.
The cap 5 is disposed within the inner tubular wall 43, has a top panel 51 that is proximate to the top end of the inner tubular wall 43, that is received in the upper tubular portion 45, that closes the receiving space 46, and that has an annular protrusion 511 engaging the upper annular groove 451 when the cap 5 is at a non-cutting position (seG FIG. P1), 452 when the cap 5 is at a cutting position (see FIG. 8) The capS further has a tubular cutter body 52 that extends downwardly from a peripheral end of the top panel 51 toward the bottom wall 44, and is movable downwardly from the non-cutting position (see FIG. 7) to the cutting position (see FIG. 8) when the top panel 51 is pressed. Preferably, the tO panel 51 and the tubular cutter body 52 are molded * as one piece from a plastic material. It is noted that the annular protrusiOfl 511 can be formed on an outer surface of the tubular cutter body 52 in other embodiments.
The tubular cutter body 52 has a beveled bottom open end 521 that slants downwardlY from a higher part to a lower part. The bottom open end 523. has a cutting end 523 that is formed at the lower part, a pushing end 525 that is formed at the higher part and that is diametrically opposite to the cutting end 523, and two opposite valleys 524 that are formed at the higher part and between the cutting end 523 and the pushing end 525. The bottom open end 521 slants upwardly from the cutting end 523 to the valleys 524 arid extends downwardly from the valleys 524 to the pushing end 525. A height of the pushing end 525 fromabottommOst end of the cutting end 523 is substantiallY equal to a distance between the non-cutting position and the cutting position. In this embodiment, the height of the pushing end 525 from the bottommost end of the cutting end 523 is substantially equal to a distance between the upper arid lower annular grooveS 451,452. The cutting end 523 is more adjacent to the bottom wall 44 than the pushing end 525.
The bottle cap further includes a tearable lid 6 that is disposed removably around the upper tubular portion and that covers the top panel 51. The tearabJ.e lid 6 has a sealing ring 61 that extends around the upper tubular portion 45, a puller 62 that is fixed to the sealing ring 61 forbeingpulledbYauser, a lidp].ate 63that is disposed above the top panel 51, and a plurality of spaced apart tearable connectorS 64 that interconnect the lid plate 63 and the sealing ring 61. The sealing ring 61 has an inner surface that is formed with an annular ridge 612 for engaging the outer annular groove 453 of the upper tubular portion 45, and a bridge 613 that bridges a discontinuation in the sealing ring 61. The puller 62 has a connection sectiOn 621 that is fixed to the sealing ring 61 adjacent to the bridge 613, and a free section 622 that is riot fixed to the sealing ring 61. The tearable lid 6 serves to prevent a user from undesirably pressing the top panel 51, thereby avoiding an undesired movement of the cap 5.
An operation of the bottle cap is described as follows.
eferriflgt0FIG. 7, tecap5i5atthefl0fl_CUttingP03iti0f where the cutting end 523 is proximate to the bottom wall 44. The puller 62 is pulled outwardly so as to break the bridge 613 and disengage the annular ridge 612 from the outer annular groove 453. Therefore, the tearable lid 6 can be entirely removed from the upper tubular potion 45, and the top panel 51 is accessible. Thereafter, referring to FIG. 8, when the top panel 51 is pressed, the annular protrusion 511 is moved downwardly from the upper annular groove 451 until the same engages the lower annular groove 452. Thus, the cap 5 is at the cutting position, where the cutting end 523 cuts the bottom wall 44. Downward displacement of the tubular cutter body 52 is equal to the distance between the upper and lower annular grooves 451,452.
Referring to FIGS. 8, 9, and 10, when the cap 5 is moved downwardly to the cutting position, the cutting end 523 cuts a portion of the periphery end of the bottom wall 44. A gap is formed between a cut portion 443 of the bottom wall 44 and the bottom open end 521. Meanwhile, the pushing end 525 pushes downwardly a part of the connection portion 445 of the bottom wall 44. Thus, a portion of the bottom wall 44 inclines downwardly from the connection portion 445. The additive in the receiving space 46 is able to easily fall into the bottle 3, thereby mixing the additive and the substance in the bottle 3.
Since the pushing end 525 pushes the bottom wall 44 downwardly after the bottom wall 44 is cut, the cut portion 443 can be moved away from the bottom open end 521 and can permit the additive to fall easily therethrough..
Since the bottom wall 44 and the inner tubular wall 43arernoldedaSoflepiece, oadditionalprOCeS5iSrQqr to attach the bottom wall 44 to the inner tubular wall 43, thereby lowering a production cost and preventing the additiVe from contamination. Moreover, the bottom wall 44 is securely connected to the inner tubular wall' 43 even under heat or cold such that undesired leakage of the additive is prohibited.
