2. Brief Description of the Prior Art
Drinking straws are well known in the art. The straws have generally a substantially circular cross-section. In order to facilitate the bending of a portion thereof with respect to another portion, it is well known to provide the straw with several corrugations so as to form a intermediate flexible portion between two linear portions of the straw (see U.S. Pat. No. 2,094,268—Friedman).
EP1095600 discloses a straw provided with a cap with lateral openings, said cap being able to slide along the straw between a closed position in which the lateral openings of the cap are laying along the outer face of the straw (position not allowing to suck liquid through the straw), and an open position in which the openings of the cap extend above the upper end of the straw, whereby enabling to suck liquid through the cap. The straw is provided with a protuberance for limiting the movement of the cap with respect to the straw, i.e. for preventing the complete removal of the cap from the straw.
CN2764256 discloses a cap covering the end and outer face of the straw, the cap is provided with a small opening at the top of the cap. The bottom of the cap is provided with a plate.
JP2001-258713 discloses a cap for a straw, said cap being connected to a ring via a flexible band, said ring being adapted to be mounted along the straw, so as to remain near the end of the straw when opened.
U.S. Pat. No. 6,565,899 discloses a drinking straw closed with a cap provided with a lollipop.
US20066144955 discloses a drinking straw provided with a pump combined display area and prize delivery system, said pump being located between the two ends of the straws.
PCT/US98/12897 discloses in FIG. 3 a straw constructed with an independent container 30 constructed for insertion within the straw. The prize, such as a US currency, will be rolled and inserted in the container, said container being associated with a cap or cover. The straw with container is placed within a outer protective closure/container 23. The user has first to remove the straw from its outer protective closure before being able to use its straw. The outer protective closure forms the system for indicating whether or not a container has possibly be opened. Furthermore, as long as the container is placed within the straw, it has been observed that the straw (taken away from its protective enclosure) placed in a drinking glass containing a drinking liquid, especially a sparkling liquid or a bubbling liquid had the tendency to move upwardly, whereby being at risk to fall or pivot away from the glass.
SUMMARY OF THE INVENTION
The present invention has for subject matter a cap having a recipient intended to contain an article or a prize or an award, the opening or re-closing of which is visible for the person receiving a straw provided with a cap, whereby said person can easily determine whether the container has been opened by people wanting to know by advance which cap comprises a winning article, award or prize, said cap being moreover adapted to be mounted on a straw used in a drinking glass containing a sparkling liquid, without risk for the straw to pivot around an edge of the glass and to fall.

DESCRIPTION OF PREFERRED EMBODIMENTS
FIG. 1 shows a cap 1 for a drinking channel of a drinking straw 2 for drinking a liquid contained in a recipient placed in an air atmosphere. FIG. 9 shows the cap 1 mounted on the end of the drinking straw 2. In fact legs of the cap 1 are inserted within the drinking channel 3 of the straw 2.
The cap 1 is mounted removable with respect to an upper end of the drinking channel of the drinking straw, whereby enabling its removal from the drinking straw so as to enable a normal use of the drinking straw.
The cap 1 comprises (see FIG. 3):
a container 4 provided with at least one wall defining a chamber 5 adapted for receiving an article (not shown), and with a band 6 to be torn from the container wall 4 for enabling to open the container 4 and to divide it into three parts, so as to have access to the article present within the chamber, possibly after removal of a sealing means,
a body 7 having one end attached to the container 4 and another end provided with a portion 7A having an outer shape adapted to enter at least partly within the drinking channel 3 through said upper end of the straw 2.
The body 7 comprises three flexible legs 8 adapted to exert a pressure on the wall(s) of the drinking straw, preferably the inner wall of the drinking straw, when the said portion 7A of the body 7 extends at least partly within the drinking channel. The legs 8 extend advantageously within the drinking channel, so as not to deform the upper end of the drinking channel
The body 7 is adapted so as to form with the drinking channel 3 at least one air passage 9 between the drinking channel 3 and the gas atmosphere when the body 7 extends at least partly within the drinking channel 3. Such an air passage enables that when the straw provided with a cap is placed in a drinking glass containing a liquid, such as a bubbling liquid, the bottom end of the straw remains in the vicinity of the bottom of the glass, i.e. the straw is not moving upwardly.
For ensuring air passage between the drinking channel 3 of the straw 2 and the outer gas atmosphere or air environment, the body 7 is provided with a series of grooves 10 comprising each a first portion (peripheral) 10A substantially parallel to the central axis A of the straw 2, and a second portion 10B substantially radial with respect to the central axis A of the straw 2. Said second radial portion of each groove 10 is intended to extend at least partly above the upper end of the straw 2, whereby the grooves 10 form air passage between the drinking channel 3 of the straw and the outer environment. Such air channels are shown in FIGS. 15 and 16. In the embodiment shown, the first peripheral portions 10A and the second radial portions 10B are communicated the one with the other by means of a circular groove 71A.
In the embodiment of FIG. 15, the body 7 is not provided with a central channel extending within the body as in the embodiment of FIG. 3.
According to a possible embodiment, the body 7 is provided with a central channel 9 as shown in FIG. 3, as well as outer grooves 10 as shown in FIGS. 15 and 16, whereby ensuring air passage between the body 7 and the straw 2, and trough the body 7.
The container 4 comprises a first container portion 4A and a second container portion 4B, said portions 4A,4B being connected through the band 6 before its tearing. For controlling the tearing of the band 6, a groove 11 extends between a first edge 6A of the band 6 and the first container portion 4A, while another groove 12 extends between the edge 6B (opposite to edge 6A) of the band 6 and the second container portion 4B. After tearing of the band 6, the second container portion 4B can be placed a side of the first container portion 4A (see FIG. 5), whereby enabling to have access to the chamber 5 of the container 4.
For facilitating the tearing of the band 6, the band 6 is provided with an extension part 13 at the end of the band to be the first to be torn. Said end of the band to be first torn is advantageously separated from the first container portion 4A and second container portion 4B by two cuts 14 for facilitating the initial tearing by decreasing the initial tearing force. For facilitating the initial tearing of the band 6, the end 6E of the band to be first torn (end 6E provided with the extension 13 for facilitating the gripping of the band by a finger or between two fingers) is separated from the container or the opposite end of the band by at least a cut 15 shown in dashed lines, said cut 15 being advantageously connected to the cuts 14 extending along the edges 6A,6B of the band 6. (see FIG. 18, in which the extension is partially cut)
After tearing the band 6 away, the container 4 is divided into a bottom portion 4A and a top portion 4B. The top portion 4B consists of a ring 16 with a central opening 17 (see FIG. 14) adapted to receive a plug 18 for sealing said opening 17. The plug 18 has a skirt 19 having a length L greater than the breadth B of the band 6. The length of the skirt 19 is advantageously such that, before the tearing of the band 6, at least a portion of the skirt 19 contacts the inner wall of the chamber 5 defined within the first container portion 4A. This enables that after tearing the band, the free end of the skirt 19 is still contacting the first container portion and remains attached to said first container portion. The second container portion can then be removed by exerting a simple pushing force. This system avoids also that after the tearing operation of the band 6, that the second container portion falls on the ground or within a glass.
After removal of the band 6 and opening of the first container portion by pushing away the second container portion 4B, it is possible to have access to the chamber 5 in order to collect the award or stone or other elements present in the chamber 5.
The chamber 5 can be closed back by pushing the second container portion 4B onto the first container portion, so that the skirt 19 of the plus of the second container portion enters into the chamber 5 of the first container portion.
As the opening of the container needs the tearing away of the band 6, it is possible by a simple view control to determine whether a container has been opened by an employee before giving the cap or the straw with cap to a client or a guest. Indeed, when being opened the skirt of the second container portion is visible or in case the skirt 19 of the plug 18 has been pushed into the chamber 5 of the first container portion, the total length of the cap is reduced. (sees FIGS. 7 and 8) It enables thus to deliver at least one article or at least two different articles in a randomly way to several people, without prior knowledge of the winning cap(s) or loosing caps by distributing to several persons drinking straws provided with a cap as disclosed in the present specification.
In order to still improve the check of the non opening of the cap before the distribution thereof in a random way, the skirt of the plug is advantageously made in a colour different from the colour of the first container portion 4A, as well as in a colour different from the colour of the ring 16 of the second container portion. Said plug has advantageously a fluorescent/phosphorescent colour. Said skirt can also have an outer surface with different aspects (with or without colour difference, preferably with colour difference), such as the presence of one or more marking, such as lines, designs, points, a rugosity different from that of the band 6, coating with a different feeling or touch, etc. This could be very helpful for people having problems with the view.
As soon as the band 6 is removed away, the coloured skirt will be well visible.
In order to be able to see a portion of the skirt 19 after pushing it into the chamber 5 of the first container portion 4A, the inner wall of the chamber 5 of the first container portion 4A is provided with a stop 20 (see FIG. 17) for limiting the entry of the skirt 19 into the chamber 5. This enables that after pushing the skirt 19 into the chamber 5, the free end of the skirt 19 abuts the stop 20, whereby leaving a ring portion of the skirt still visible. The stop 20 can have other forms, such as the form of one or more fins parallel to the central axis B of the chamber 5, fins extending up to the bottom of the chamber 5 of the first container portion 4A (see FIG. 14).
In order to prevent, after sealing the opening 17 of the chamber 5 with the plug 18 of the cap with the band not torn, an easy removal of the plug 18 from the ring 16 of the second container portion, the skirt 19 of the plug is advantageously provided with a groove 22 adapted to receive a ring extension 21 on a inner wall of the band 6 and/or the first container portion 4A. When the plug 18 seals the opening 17, the ring extension 21 extends within the groove 22, so as prevent removal of the plug 18 in its sealing position to be removed when the band is not torn away.
The band can possibly be provided with a groove adapted to receive an abutment portion or a stop portion of the skirt 19 of the plug 18.
In the embodiment of FIG. 19, the skirt 19 has adjacent to its free end a second annular groove 22A adapted to receive a annular protrusion 21A located at the level of the cut 12.
The cap of FIG. 1 is manufactured in two pieces, namely a first piece comprising the body 7, the first container portion, the band 7 and the ring 16 of the second container portion, and a second piece consisting of the plug 18. (see FIG. 14) As the opening 17 is not closed by the plug 18, employee and/or manager can place article, awards, a perfume, etc. into the chamber of one or more open cap before sealing the opening 17 of each cap with a plug 18. For losing cap, the chamber is provided with a losing article, award, etc. having advantageously the same weight as the winning article, winning awards, etc, before sealing the opening 17 with similar plug as used for the winning caps.
Winning caps and losing caps can then be mixed together, whereby not allowing to determine by advance if a cap contains a winning article/award or a losing article/awards.
In the embodiment of FIG. 1, the band 6 when torn enables a complete separation of the second container portion with respect to the first container portion. The band 6 in said embodiment extends all around the wall of the container 4, i.e. the first end of the band 6 to be torn being adjacent to the other end of the band to be torn at the end of the tearing operation.
According to a further embodiment similar to that of FIG. 6, the band 6 extends not all around the wall of the container 4, whereby after tearing the band, a flexible bridge 25 still forms a link between the first container portion 4A and the second container portion 4B. (see FIG. 20)
In the embodiment of FIG. 1, the body 7 is provided with one flexible leg 8bis. Before being inserted into the drinking channel 3 of the straw 2, the leg 8bis has a protuberance 8A which is away from the central axis B by a distance which is greater than the distance separating the protuberance 8A of the two other legs 8 from said central axis B. Thus when not inserted into the drinking channel of the straw 2, the protuberances 8A of the three legs 8, bis extend along a circle with a radius grater that the radius of the straw.
For inserting the legs 8 into the drinking channel 3 of the straw, a pressure has to be exerted on the legs 8,8bis so that at least the leg 8bis is moved towards the two other legs 8, whereby the protuberances 8A of the legs 8, 8bis extend along a circle with a radius lower that the radius of the drinking channel 3.
After inserting the legs 8,8bis into the drinking channel 3, the legs moved away from their compacted position, whereby the protuberances 8A move towards and contact the inner wall of the drinking channel. The legs can, if required, further pushed within the drinking channel 3, so that a face of the body 7 contacts the upper edge end of the straw 2.
The protuberances 8A of said legs lay, when not being inserted within the drinking channel 3 of the straw 2, along an outer circle with a diameter comprised advantageously between 1.5 and 1.9 times the diameter of the portion of the straw adjacent to the upper end, in which the legs have to be inserted.
In the embodiment of FIG. 1, the body 7 comprises:
(a) a first body portion 70 attached or connected to the container 4, and
(b) a second body portion 71 (in the form of a tube) adapted to enter within the drinking channel 3,
whereby the means for forming the air passage between the drinking channel and the gas atmosphere when said second body portion extends within the drinking channel comprises at least an air channel 90 extending in the first body portion 70 and in the second body portion 71.
The air channel 90 extending into the first body portion comprises:
(a) a first channel portion 90A extending between an opening (bottom opening 90E) of the second body portion (tube) 71 directed towards the drinking channel 3 when the said second body portion 71 extends within the drinking channel 3 of the straw 2, and an upper closed end 90C directed towards the container 4 (said upper closed end laying in the first body portion 70), and
(b) two second channel portions 90B extending each between an opening 90D located between the upper closed end 90C and the bottom opening 90E of the first channel portion 90A, and an opening 90F located along the lateral outer face of the first body portion 70.
The two second channel portions 90B are advantageously aligned with an central axis C substantially perpendicular to the axis B. An angle of about 180° is thus formed between the two second channel portions 90B, with respect to the axis B.
The air channel portion 90A and advantageously 90B have advantageously a diameter or a cross section adapted for enabling the natural downwards flowing of drinking liquid, in case drinking liquid would enter within the said air channel. For example, said channel portion will have a diameter (In the present specification diameter means diameter or equivalent diameter, the equivalent diameter being equal to 4 times the open section divided by the periphery of the open section) of at least 2 mm, preferably comprised between 2.5 mm and 6 mm.
The cap of FIG. 11 is similar to the cap of FIG. 1, except that a sleeve 30 is glided onto the tube or second body portion 71, so as to increase the outer diameter of the second body portion 71 in function of the inner diameter of the straw.
In order to prevent accidental removal of the sleeve 30, the sleeve is provided with an annular protuberance 30A adapted to be fitted into an annular groove 71A of the second body portion 71. FIG. 12 is a cross section view of the cap of FIG. 11 without the plug 18. FIG. 13 is a view similar to FIG. 12, but with a thicker sleeve 30.
The cap of FIG. 21 comprises three pieces, namely
a piece 7 with the air channel 9,
a container 4, and
a plug 18.
The container 4 is attached on the piece 7 by clipping. For example, the container is provided with two arms 45 with fingers 46 adapted to be inserted within the second channel portions 90B.
The caps disclosed in the embodiments shown in the figures are suitable for delivering at least one article or at least two different articles in a randomly way by distributing to several persons drinking straws provided with a cap, each drinking straw being advantageously distributed with a drinking glass. Said method for randomly distributing winning articles and non winning articles comprises the following steps:
providing a series of caps with the closing plug away from the ring 16 so that the opening 17 forms an opening for the container chamber 5,
introducing at least one article through the opening 17 into the chamber 5 in one or more caps or introducing one article through the opening 17 into the chamber 5 in some caps and introducing another article (for example non winning article) through the opening 17 into the chamber 5 for some other caps,
closing the opening 17 of the second container portion of the caps by pushing closing plug into the opening 17, before or after associating the caps with drinking straws;
randomly mixing the caps or the straws provided with the caps;
randomly distributing the drinking straws with closed caps, advantageously with drinking glasses and/or drinking bottles to people,
whereby each person receiving a drinking straw provided with a closed cap, possibly after removing the cap from the drinking straw, has to tear the band so as to have access to the chamber of the container, so as to collect the article (winning or non winning) possibly present within the chamber of the cap. When receiving a straw provided with a cap, the people or guest can determine whether or not the cap has already been opened.
The cap of FIG. 22 is similar to the cap of shown in FIG. 14, except that the body 7 comprises a pin like shaped element 50 adapted to enter or prick into a food for facilitating the individual eating of said food, and/or for generating some fun and surprise when eating some meals, lunch, diner, such as during a party or a reception, etc. The cap of FIG. 22 can also be pricked into a cloth, such as into a tie, etc. The pin like shaped element 50 can optionally replaced by a clip element, a ring, etc. so as to attach the cap, for example to a finger, an ear, etc.
The cap of FIG. 23 is similar to that of FIG. 22, except that the pin 50 has been replaced by a clip mechanism 51, for example suitable for attaching to an ear. Said mechanism has a pivoting portion 51A (arrow H).
The cap of FIG. 24 is similar to the cap of FIG. 22, except that the pin 50 has been replaced by a flexible band 52, the end of which is attached to the plug 18 adapted to close the opening 17 of the cap 4. When closing the opening 17 by the plug 18, the band forms a ring.
The caps as shown in the figures can also be used as such for distributing awards, messages, etc in a randomly way. The invention further relates then to a cap comprising a container provided with at least one wall defining a chamber adapted for receiving an article, and with an element to be torn at least partly from one of said wall for enabling to have access to the article present within the chamber, possibly after removal of a sealing means, in which the element to be torn is a band of the container wall(s) extending between a first container portion and a second container portion, whereby said band is adapted when torn from the container wall(s) for allowing at least a relative motion between the first and second container portions, preferably a take away motion between the first container portion and the second container portion.
Said cap has then one or more further characteristics of the two other caps of the invention, especially one or more characteristics as stated in the attached claims
