EP2505108B1 - Closing system for a child's drink bottle or a child's drink container - Google Patents

Description

The invention relates to a closure system for a child drinking bottle or for a child drinking cup and a children's drinking bottle or a child drinking cup, which is equipped with a closure system.

Such children's drinking bottles or cups have a container for receiving the liquid. The container is closed by a lid, which has a special mouthpiece, which facilitates drinking.

For example, children's drinking cups are known in which a one-piece made of a relatively strong plastic lid is provided with an integrally formed with the lid drinking spout. For trouble-free drinking, the lid is provided with a vent hole. Before an undesirable leakage of liquid, the mouthpiece may be provided with a special insert of an elastic material with a slot-shaped opening, which emits the liquid by suction on the mouthpiece. For the same purpose, a special valve may be provided. A disadvantage of the known child drinking cup is that the mouthpiece of the same, relatively strong plastic, as the rest of the lid, and that the entire lid must be replaced when the mouthpiece is worn.

In known children's bottles, the mouthpiece is usually a sucker made of a very elastic material, such as latex or silicone, a mounting flange has at the end remote from the opening. The mounting flange is pressed by a locking ring, which is bolted to the bottle, against the edge of the bottle. The mouthpiece is removable from the locking ring and thus can be replaced individually. Such Kindertrinkflaschc exemplifies the publication DE 197 39 911 A1 , The correct and sealing fit of the mounting flange of the mouthpiece between the bottle neck and the locking ring is difficult to control from the outside. In addition, the size of the opening of the bottle neck must correspond to the predetermined size of the mounting flange of the mouthpiece.

Another child drinking bottle with a nipple with a mounting flange and a screw ring for attaching to a drinking bottle is in the GB 2 309 680 A described.

The EP 0 940 350 A2 describes a removable cover of a bottle. The cover has a closable mouthpiece on an upper plate and a vacuum valve. The mouthpiece comprises a main body in the form of a stepped pin projecting from the upper plate and having a channel. A mouthpiece part is mounted on the main body so as to be displaceable in the axial direction to open and close the channel. A closure cap can be placed on the mouthpiece and detachable from it. The channel can be opened and closed by the displacement of the mouthpiece part when attaching and removing the cap. The channel is formed by a plurality of holes arranged on a shoulder around a conical portion of the main body. Due to the training of the Through-channel on the shoulder of the stepped pin, the mouthpiece has a large diameter. In addition, the seal is uncertain because it is only given when the bottom of the movable mouthpiece part closes the channel openings. If the displaceable mouthpiece part is only slightly moved out of the closed position, liquid can escape.

The from the Swiss patent CH 681075 A5 Known Trinkflaschenverschlüssc have a screw on which is screwed onto a bottle to connect the closure sealingly with the bottle.

On this basis, it is the object of the invention to provide a closure system for a child drinking bottle or a child drinking cup, which simplifies the handling and allows flexible use.

This object is achieved by the closure system for a child drinking bottle or a child drinking cup with the features of claim 1. Advantageous embodiments are given in the further examples.

• eine Trinköffnung und
• einen Befestigungsansatz, der zwischen einem Behälterrand der Trinkflasche oder des Trinkbechers und einem mit der Trinkflasche oder dem Trinkbecher verschraubbaren Verschlussring einklemmbar ist, dadurch gekennzeichnet, dass
• das Mundstück ein axial verschiebliches Verschlusselement aufweist, das die Trinköffnung in einer ersten Position dichtend verschließt und in einer zweiten Position freigibt und
• das Verschlusselement röhrenförmig ausgebildet und das Mundstück einen Zapfen mit gleichmäßigem Außendurchmesser aufweist, der in der ersten Position in einen Längsabschnitt des Verschlusselements eingreift.

The closure system according to the invention for a drinking bottle or a drinking cup with a mouthpiece has

• a drinking opening and
• a fastening approach, between a container edge of the water bottle or the drinking cup and one with the water bottle or the drinking cup screwed lock ring is clamped, characterized in that
• the mouthpiece has an axially displaceable closure element which sealingly closes the drinking opening in a first position and releases it in a second position and
• the closure element is tubular and the mouthpiece has a pin of uniform outer diameter, which engages in the first position in a longitudinal portion of the closure element.

The mouthpiece has an axially displaceable closure element, which sealingly seals the drinking opening in a first position and releases it in a second position. Such mouthpieces are as integrated into a screw-cap bottle closure mouthpieces, for example, from the Swiss patent CH 681075 A5 known. Due to the axially displaceable closure element, a simple opening and closing of the opening in the mouthpiece is possible, in particular with the mouth or the teeth.

In a further embodiment, the closure element has a circumferential bead. The circumferential bead is preferably arranged on the user-facing end of the mouthpiece and fixedly connected to the axially displaceable closure element. The bead facilitates the displacement of the closure element with the mouth or teeth.

The closure member is formed substantially tubular and the mouthpiece has a pin which in the first position in a Longitudinal portion of the closure element engages. By engaging the pin in the Verschlußelcmcnt the drinking opening is closed in the first position. The substantially tubular closure member may have a uniform inner diameter or a variable inner diameter. Preferably, the inner diameter of the closure element is variable, and the closure element has at its end facing the user an inner diameter which is matched to the outer diameter of the pin. In a pin having a uniform outer diameter, the inner diameter of the closure member may be increased in a further towards the bottle portion opposite the matched to the diameter of the pin longitudinal portion, so that the liquid in the second position of the closure member by the portion with the enlarged inner diameter to the Spigot can flow around. In this second position, the pin does not engage in the longitudinal section with the matched to the pin inner diameter. The construction with a pin and a substantially tubular closure element is particularly simple and achieves a reliable sealing of the drinking opening in the closed state.

The above object is also achieved by the child drinking bottle or the child drinking cup with the features of claim 7. Advantageous embodiments are specified in the subsequent subclaims. The child drinking bottle or infant drinking cup according to the invention comprises a container having a container opening and a container rim, and a closure system in one of the embodiments described above.

In one embodiment, the child drinking bottle or infant drinking cup is additionally provided with a handle member inserted between the container and the locking ring, formed integrally with the container, or secured to the container with a separate attachment means.

In one embodiment, the children's drinking bottle or the child drinking cup additionally has a covering cap, which is detachably connectable to the closing ring and covers the mouthpiece. This protects the mouthpiece from contamination.

The closure system according to the invention can preferably be used for a child drinking bottle or a child drinking cup. It has a drinking opening and an axially displaceable closure element, which sealingly closes the drinking opening in a first position and releases in a second position, wherein the mouthpiece has a mounting lug which between a container edge of the bottle or the drinking cup and a with the bottle or the Drinking cup screwed locking ring can be clamped. In contrast to the known from the prior art, so-called push-pull closure systems in the invention, no matched to a particular bottleneck screw is required. Instead, a clampable attachment lug is formed on the mouthpiece. The attachment lug may in particular be a circumferential attachment flange. The clamped fastening approach a combination of the closure system with existing drinking bottles or drinking cups is possible, the equipped with a screwed with the bottle or cup closure ring. Such drinking bottles or drinking cups are widely used and are used, for example, for fixing a teat or a drinking spout on a child drinking bottle. By means of the closure system according to the invention, they can be combined in a simple manner with a push-pull system. This simplifies the opening and closing of the drinking bottle or the drinking cup.

In one embodiment, the closure element has a circumferential bead. In a further embodiment, the closure element is formed substantially tubular and the mouthpiece has a pin which engages in the first position in a longitudinal portion of the closure element. These two embodiments and their advantages have already been explained in connection with the Verschlußsystcm with a locking ring and a fuser.

According to one embodiment, the attachment portion is a circumferential attachment flange, the thickness of which decreases in the radial direction to the outside. In this case, the thickness of the mounting flange in cross-section to the outside evenly or with the formation of at least one step decrease. This embodiment can facilitate the centered insertion of the mouthpiece between a drinking bottle or a drinking cup and a locking ring and improve the sealing effect.

The above object is also achieved by a drinking bottle or a drinking cup with the features of claim 8. The bottle according to the invention or the drinking cup according to the invention has a container which can be closed with a closure system described above.

The drinking bottle or the drinking cup is preferably a child drinking bottle or a child drinking cup.

The closure ring, the fixation insert, the child drinking cup, the grip element, the mouthpiece with displaceable closure element and / or the plastic cover cap preferably consist.

the closure system from the FIGS. 12 and 13 in a further perspective view obliquely from above with a separately shown locking ring.

The child drinking cup Fig. 1 consists of a cup-shaped container 10 which is closed by a closure system. The closure system consists of a closure ring 20, in whose centrally located, circular opening a mouthpiece in the form of a drinking spout 22 is inserted. The drinking spout 22 is replaced by a fuser insert, which in Fig. 1 is not visible, held in the opening of the locking ring 20. Below the locking ring 20 and also in the region of the cup rim, a grip element 24 is arranged, which consists of two grip portions 26 and a ring 28 connecting the two grip portions 26.

Further details are better in the cross-sectional representation of Fig. 2 to recognize. The container 10 has a large, circular opening which extends to the upper container rim 16 formed by the substantially cylindrically shaped container wall. On the outside of the container rim 16, an external thread 12 is arranged. Below the external thread 12 is a circumferential projection 14 which forms a stop. The locking ring is screwed to the external thread 12 via a female thread formed on the outer circumference of the locking ring. Between the circumferential projection 14 and the locking ring 20, the grip element 24 is fixed. Below the drinking spout 22, a blind cover 32 is inserted, which is located in a passage opening of the fixing insert 30 and together with a fixing lug the drinking spout 22 is clamped between the fixing insert 30 and the locking ring 20. As a result, the passage opening of the fixing insert 30 is sealingly closed, so that no liquid can leak into the drinking spout 22 and through the opening 34.

The in Fig. 3 shown in a perspective view, the locking ring 20 is annular and has a centrally disposed, circular opening 36. In the lateral plan view of Fig. 4 can be seen the relatively flat design of the locking ring 20 and the strongly rounded on the upper side of the outer periphery edges.

Fig. 5 shows a cross section through the locking ring 20 in a radial cross-sectional plane, which in the Fig. 4 designated AA. The left in the figure arranged edge of the cross section bounded the opening 36. For connection to the container 10, the locking ring 20 is placed with the circumferential groove shown at 38 on the container edge 16. In this case, the internal thread 40 engages in the external thread 12 of the container rim. The internal thread 40 is formed on the outer periphery of the locking ring 20 and serves as a fastening means for connection to the container 10. On the side facing the container of the closure ring 20 and further towards the center is a tubular portion 42, the outer side 44 of the Container edge of a screwed container 10 adjacent. When screwing the outer side 44 forms a guide for the container edge. On the inside of the tubular portion 42, a further internal thread 46 is formed. This serves to receive the fuser insert 30. As in Fig. 2 can be seen, includes a completely screwed into the internal thread 46 fuser insert 30 is substantially flush with the lower end of the tubular portion 42 from. Within the tubular portion 42, the locking ring 20 has a surface 48 facing the container, from which a circumferential ridge 50, which is adjacent to the opening 36, protrudes. The web 50 forms a strip-shaped, circumferential contact surface for the clamping holding the attachment lug of a mouthpiece. At the outer periphery of the web 50, this passes over a conical surface 52 in the surface 48 on. Between the strip-shaped contact surface of the web 50 and the conical surface 52, a circumferential edge 54 is formed, which is pressed as well as the annular surface in the assembled state of the closure system against the attachment lug of a mouthpiece. The internal thread 46 is spaced from both the opening 36 and the further internal thread 40, which forms the fastening means for the container edge. Both distances are in the radial direction.

A fixing insert 30 for an inventive closure system is in the Fig. 6 shown in a perspective view. The fixing insert 30 has an annular portion 56 and a web 58. The annular portion 56 has a through hole 60 which is substantially circular. Circumferentially shaped projections 62 are integrally formed on the annular section 56 at three locations spaced apart at angles of 120 °, which project into the passage opening 60. The web 58 spans the passage opening 60. In this case it extends centrally through the passage opening 60 and is slightly spaced in the direction of the longitudinal axis of the annular portion 56 from the plane of the annular portion 56, so that it is particularly easy to take. The in the assembled state the container interior facing side 64 of the annular portion 56 is inclined towards the passage opening 60 and towards the mouthpiece.

In the plan view of Fig. 7 the fixation insert is shown again. Particularly well recognizable is the arrangement of the circular portion-shaped projections 62 and the center of the passage opening 60 spanning web 58. Furthermore, the cross-sectional planes AA, BB and CC are shown, which represent the views of FIGS. 8 to 10 specify.

In the cross section drawing of Fig. 8 along the in Fig. 7 AA-designated plane is the slightly curved and spaced from the annular portion 56 shape of the web 58 can be seen particularly well. On the outer circumference of the annular portion 56, an external thread 66 is formed, the single outwardly projecting thread tooth rotates just once around the annular portion 56, as in the Fig. 6 is recognizable. The designated with 68 outer edge of the annular portion 56 and the adjacent, arranged in the plane of the annular portion 56, strip-shaped surface 70 cooperate in the screwed state with the mounting boss of a mouthpiece and press it against the locking ring 20th

In the cross-sectional view along in Fig. 7 plane designated BB, shown in FIG Fig. 9 , the profile of the annular portion 56 is particularly well recognized. The inclination of the surface 64 in the direction of the passage opening becomes particularly clear. The approximately cylindrical surface 72 forming the outer circumference of the annular portion 56 is so in height to the length of matched tubular portion 42 of the locking ring 20, that both close to each other approximately flush.

Fig. 10 shows again a cross-sectional view of the annular portion 56 of the fixation insert 30 along in FIG Fig. 7 with CC designated level in an area with molded projection 62. This protrudes into the through hole 60 and serves to fix a blind cover, which is insertable into the through hole 60. The blind cover, not shown, has a circumferential latching lug, which can be engaged behind the projections 62 to hold the blind cover.

Fig. 11 shows a cross-sectional view of a closure system with a locking ring 20 and a fixing insert 30, between which a mounting lug 102 of a mouthpiece 100 is clamped. The mouthpiece 100 has an axially displaceable closure element 104, which is substantially tubular and is inserted with its outer diameter 108 into an approximately cylindrical opening 106 of the mouthpiece 100. The inner diameter of the closure member 104 is variable over the length of the sliding closure member 104 and has a relatively small diameter in a longitudinal portion 110 facing the user, which is tuned to the outer diameter of a pin 112 engaging the portion 110. By engaging the pin 112 in the longitudinal section 110 of the closure element 104, the drinking opening is closed in the illustrated first position of the closure element 104. Below the longitudinal section 110, the inner diameter of the closure element 104 widens in the region of the step 114, so that below the step 114, a gap 116 between the pin 112 and the inner wall of the closure element 104 is formed. At the end of the closure element 104 facing the user, there is a circumferential bead 124 on the outside, which is arranged approximately at the level of the longitudinal section 110.

The attachment portion 102 of the mouthpiece 100 has a radially outwardly decreasing thickness. A step 118 separates two areas of different thickness from each other. A fastening surface 102 facing the contact surface 120 of the locking ring is pressed when clamping the mouthpiece 100 between the locking ring 20 and fuser 30 against the inside radially of the step 118 arranged thicker portion of the mounting boss 102. By contrast, an upper contact surface 122 of the fixing insert engages in the region of the thinner section of the fastening flange 102 arranged outside the step 118.

The axially displaceable closure element 104 is guided in an approximately cylindrical housing section 126 of the mouthpiece 100. This housing portion 126 is connected at the lower end to the lower end of the pin 112 via two webs 127. Furthermore, the housing portion 126 is connected to the mounting boss 102 via a domed conical portion 128 extending from the outer surface of the housing portion 126 and another substantially cylindrical housing portion 129.

In the Fig. 12 another mouthpiece 130 is shown with push-pull system. At its outer periphery, the mouthpiece 130 has a mounting boss 132. The attachment lug 132 merges into an approximately conical housing section 134, which merges into a further, approximately conical housing section 136 with a greatly reduced opening angle relative to the housing section 134. Below the housing portion 134 and fixedly connected thereto, extend two axially oriented webs 138, which open at its lower end in a ring-disk-shaped connecting piece 140.

Hatched is an axially displaceable closure element 142, which is guided in an approximately cylindrical opening of the conical housing section 136. In the in Fig. 12 shown first position, the drinking opening of the mouthpiece 130 is closed. The axially slidable closure member 142 has a circumferential bead 144 at its user facing end. The closure element 142 is passed through the conical housing section 136 and extends below the conical housing section 134 further in the axial direction between the two webs 138 up to the annular disk-shaped connecting element 140.

Fig. 13 shows the mouthpiece 130 with the sliding closure element 142 in a second position in which the drinking opening is released. The same reference numerals are used as in the FIGS. 13 and 14 , In addition to that already related to Fig. 12 In the second position of the closure element 142, a cylindrical portion 146 of the closure element 142, which is formed below the bead 144, is visible. Furthermore, it can be seen a pin 148 which is attached to the annular connector 140 and is made integrally therewith and in axial Direction extends into a cylindrical opening of the sliding closure element 142. Between the pin 148 and the substantially tubular closure element 142, a ring-shaped gap 150 can be seen, through which the liquid can flow in the illustrated second position of the closure element.

Another perspective view of the mouthpiece 130 provides the Fig. 14 in which the closure element 142 in the first, also in Fig. 12 shown position. In this closed position and in the view obliquely from above, it can be seen the engagement of the upper end of the pin 148 in the cylindrical opening of the closure element 142. This closes the drinking opening. Furthermore, in Fig. 14 a closure ring 160 through which the mouthpiece 130 can be passed from below, wherein a trained within the conical surface 134 paragraph 162 cooperates with an inner periphery 164 of the locking ring 160. By screwing the locking ring 160 with the upper edge of the container of a drinking bottle or a drinking cup of the attachment lug 132 is sealingly clamped between the locking ring 160 and the container edge.
