Description

Drinking cup cover

Technical Field

The invention relates to a drinking cup cover for a drinking cup according to the invention.

Background

Such drinking caps are disclosed in EP 2532601B 1. The drinking stub is designed as a flexible small tube made of plastic, which can be bent over to close the built-in flow channel. The independence of the small pipe can ensure that the bending posture (stellung) of the sealing performance of the drinking cup cover is ensured through the sleeve cover, and the sleeve cover can be locked with the lower part of the drinking cup cover through the clamping and locking connecting piece. If the cap is released and turned back, the drinking stub can return to its original shape again on the basis of the elastic restoring force, and the built-in flow channel is released again. Such drinking cup lids are provided in particular for use in sports activities, in which water should be drunk directly from the bottle through a drinking nipple, also called drinking spout. For this purpose, the operation must also be as simple as possible and should be possible, in particular, with one hand. A disadvantage of the known drinking cup lids is that the closure of the pivotally supported sleeve is at the same time obstructive. The shroud must be restrained by the fingers when drinking through the drinking nipple.

Disclosure of Invention

The object of the invention is therefore to provide a drinking cup lid with a drinking stub, which can be bent without an additional jacket, is held in the bent position and thus results in a sealed closure.

This object is achieved according to the invention by a drinking cup lid according to the invention, in particular in that the drinking stub is held in a guide slide which is supported in a hinged and/or displaceable manner on the base element, and the bent-over drinking stub can be supported inside a receiving space enclosed by a rim.

In contrast to the prior art, in which the receiving space for the drinking stub is formed in a hollow space below the jacket, the receiving space is formed directly on the base element according to the invention. The securing of the drinking stub in the bent position is effected by the guide slide, which is located on the upper side of the receiving chamber in the locked position. By virtue of the fact that the drinking stub does not simply project freely from the base element according to the invention, but is held in the guide slide with its defined bearing point, a defined bending point is achieved.

In addition, in a preferred embodiment: the position of the guide slide with respect to the outlet opening in the base element is arranged such that two bends are made. The S-shaped configuration of the drinking stub, as seen in cross section, thus results in the built-in drinking channel being blocked even at the second location and a reliable blocking being achieved.

Important to the present invention is the mutual cooperation between the position of the guide slider and the elasticity of the drinking spout. The guide slider is pressed down by the thumb, tipping forward and carrying the drinking stub there. In the transition to the more horizontal position (Lage), the joint point of the guide carriage is guided by the sliding guide until it reaches a path which allows a linear retraction movement. The user can therefore pull back the guide slide slightly after pressing down the drinking stub, i.e. radially outward, where the guide slide is caught on the unlocking button and thus also holds the bent drinking stub underneath. The locking position of the guide slide is maintained in that the guide slide is supported in a hinged manner and the spring force of the deformed drinking stub presses the guide slide firmly against the unlocking button.

In order to be able to drink water again from the bottle, the user merely has to push the guide slide slightly forward, so that it is disengaged from the unlocking button. With a slight pressure, by which the locking is triggered, the guide projection on the guide slide is also pressed back into the sliding groove, so that the guide slide can be erected due to the elastic return of the drinking mouthpiece. Next, the user pushes the guide slide forward again, wherein the drinking stub is bent and the guide slide moves back into its blocking position.

In order to provide a still higher level of safety with respect to unintentional opening and with respect to unintentional dispensing of the beverage, a safety slide is preferably provided, which can be moved into a position above the receiving space, where it additionally limits the bent drinking stub and/or ensures the guide slide, for example in that it forms a latching connection with the guide slide. Because the safety slide can only be moved in translation, tipping of the guide slide does not occur as the guide slide engages the safety slide. The user must first of all bring the safety slide into an outer position in order to be able to move the guide slide and the drinking stub as a whole, and then must trigger the unlocking button already described above in order to release the guide slide.

In the drinking cup lid according to the invention, it is therefore advantageous for the pivotal movement of the guide slide, which brings it into a lying position in which the drinking stub is clamped, to be linked to the outward following radial displacement for safety purposes. The combination results in a self-securing transport position which can also be cancelled again only by a displacement in the radial direction.

The radial displacement can be performed by the user himself by a pulling-back movement. However, it is preferably provided that the guide slide slides with a sliding edge or sliding surface on the guide runner when the user pivots the guide slide downward. This forced guidance is achieved when the guide slide is pressed until a little below the transport position. The guide slide is then pushed outward in its outer, rear inclined position with the rear bearing edge slightly raised, so that the bearing edge is above the bearing surface. This has the advantage that the user only has to press down on the guide slide in order to establish safety. If the user releases the guide slide, the surfaces come to bear against one another and the transport position is ensured.

In order that the user does not have to perform two different types of movements during the closing, a preferred embodiment also provides at least one additional spring element which acts on a bearing pin on the outer side of the guide slide. The user then merely has to pivot the guide slide with the drinking stub downwards. The required retraction movement for establishing the locking is effected by spring elements which linearly displace the guide slide back into the blocking position.

Detailed Description

Fig. 1 shows a drinking cup lid 100 in cross-section, which is made up of the following important components:

a base element 10 made of hard plastic;

an insert element 20 made of soft plastic or rubber;

a guide slide 30;

a safety slide 40; and

an unlocking key 50.

The base element 10 has an outer, substantially cylindrical body which extends from a lower edge, where the screwing thread starts, to an upper edge 15. By screwing the thread, a sealing connection with the neck of a drinking cup or bottle, in particular a thermos, can be established.

The interior of the base element 10 is divided by a floor 11 which has a plurality of

openings

12, 19. One aspect relates to the pouring opening 19. In addition, a plurality of small ventilation openings 12 are present in the base plate.

The insert element 20 rests from the underside against the base 11 in the base element 10 and is connected in a sealing manner thereto. Adjoining the pouring opening 19 covered by the insert element 20 is a drinking spout 23 which has an internal flow channel 24 which originates from the inlet opening 21.

In the region of the ventilation opening 12, the insertion element 20 is provided with a small dome which is expanded by a spacer 13 which projects downward from the base plate 11.

The closed shipping position of the drink bottle closure 100 is shown in fig. 1. The drinking stub 23 is bent twice, specifically once radially to the left and outwards, starting from the outlet opening 21, from where it turns around at the bend 22 and extends in the other direction. By means of the double folding, on the one hand the drinking stub 23 can be formed longer and nevertheless be retained inside the rim 15, and on the other hand a greater security against liquid outflow is provided by the double closing of the inner flow channel 24. The part of the drinking stub 23 located behind the bend 22 is located completely inside the receiving space 14, which is surrounded by the rim 15 and is delimited downwards and back by the base 11. The position of the bent drinking stub 23 is ensured on the one hand by the guide slide 30, which is in the blocking position in fig. 1. The guide carriage 30 has a bearing pin 31 on both sides for pivotable bearing in the base element 10.

On the other hand, the safety slide 40 is brought into a locked position in fig. 1 in which the guide slide 30 is above the accommodating chamber 14. The safety slide 40 is guided in the rail 16. This safety slide ensures the guide slide 30 and prevents the drinking stub 23 from being unintentionally raised and thus from releasing the flow channel 24 located inside. The rails 16 are formed on both sides on the inner side of a U-shaped clip 17, which extends radially outward as far as beyond the edge 15 of the base element 10. The clip 17 can also be used for carrying in the closed position.

The opening process start is shown in fig. 2 in a further sectional view. The safety slide 40 has been pushed into its end position in the bracket 17 outside the edge 15, as a result of which the guide slide 30 can be moved without being impeded. The safety slide 40 is held in this attitude by the click projection 41.

Despite the release, the guide slide 30 cannot be sprung up by itself because it is also positively coupled to the housing 10 over a short distance, so that it can be pushed in the radial direction but cannot rotate about its bearing pin. To overcome this intermediate position, the guide slide 30 is pushed radially forward in the central direction by pressing lightly on the unlocking button 50 and is therefore free on its rear end as shown in fig. 3. The guide slide 30 is now no longer secured against rotation relative to the base element 10 and can be raised again on the basis of the restoring force of the bent elastic drinking stub 23.

The drinking posture is shown in fig. 4. The drinking stub 23 is fully unfolded so that the built-in flow channel 24 is open between the outlet opening 21 and the end of the drinking stub 23. The drinking stub 23 is held in the guide slider 30 so that the two assemblies occupy substantially the same angular position.

Fig. 5A, 5B each show a closed position similar to fig. 1, but in perspective. Not only is the guide slide 30 guided, but also the safety slide 40 is located inside and completely covers the opening of the receiving chamber 14 in a substantially horizontal position above the receiving chamber 14. Projections are formed on the upper sides of the guide slider 30 and the safety slider 40, which form gripping grooves to facilitate manipulation of the drinking cup lid 100 by pushing these components.

The guide slide 30 is secured on the one hand in the receptacle 18 in the base element 10 by means of a bearing pin 31 which can be seen in the partial sectional view in fig. 5B. On the other hand, the guide slide 30 rests with its rear edge 32 on a shoulder in the base element 10. The guide slide is held with its front edge by a safety slide 40. As is likewise recognizable in fig. 5B, the support receptacle 18 is designed as a double support receptacle or as an elongated hole. The bearing pin 31 can therefore be changed in its position by being displaced.

In fig. 6A, the safety slide 40 has been transferred into its outer end position in the clip 17, so that the safety of the guide slide 30 has been cancelled again on one side. However, the guide slide 30 with its rearward edge 32 also rests on the bearing 10.1 on the base element 10 (see fig. 6B) and this position is maintained by the spring force of the drinking stub 23. The bearing pin 31 is in a rear, outer position within the bearing receptacle 18.

The guide slide 30 is pushed forward, for example, by pressing the unlocking button 50, as shown in fig. 7A. In this case, the bearing pin 31 is moved in the bearing receptacle 18 into a front inner position. At the same time, the rear edge 32 is disengaged from the bearing 10.1, and the guide slide 30 can thereby be pivoted freely about the bearing pin 31.

Based on the return shape of the drinking stub 23, it stands on itself and completely stands up the guide slide 30 connected thereto until it assumes the drinking position shown in perspective in fig. 8, which corresponds to the position in section in fig. 4.

While the previous figures relate in particular to the opening process, fig. 9 and 10 show the transition from the drinking position according to fig. 4 and 8 into the safe transport position according to fig. 1, 5A or 5B.

Starting from the use position or drinking position in fig. 8, the user presses from above onto the guide slide 30 and presses it downwards. Thereby, it also deforms the drinking stub 23. If the user presses the guide carriage 30 still further, for example, until it is pressed down below the upper side of the housing into the receiving space 14, it enters with its front lower sliding edge 33 onto the curved concave surface of the guide runner 13 in the base element 10.

Fig. 9 shows the first contact of sliding edge 33 with guide runner 13. Here, the guide slider 30 is slightly inclined inward and downward. At the same time, the rearward side of the guide slider 30 is slightly raised. The rear edge 32 is located above the support 10.1 on the base element 10. Since there is contact on the one hand on the guide link 30 and, on the other hand, the support pin 31 is held in the receptacle 18 (see fig. 6B, 7B), the force exerted by the user is deflected such that the pin 31 is pushed radially until it is in the rearward position inside its receptacle 18. If the user then releases the guide slide 30, due to the elasticity of the drinking stub 23, is pushed upwards, so that the rear edge 32 rests on the support surface 10.1. Thus already enabling the transport attitude to be ensured. Additional safety can finally be achieved by means of a safety slide 40, which prevents the guide slide 30 from moving out of the blocking position as a result of an unintentional nudge.

Fig. 11A shows a drinking cup lid 100' according to a second embodiment in a perspective view. A safe transport position is shown. The guide slider 30, the safety slider 40 and the base element 10 are substantially unchanged with respect to the first embodiment.

A compression spring element 25' is provided as a distinction, which is arranged between the bearing pin 31 and the base housing 10. In the embodiment shown, the compression spring element is part of the insert element and is therefore formed in one piece with the drinking stub 23' from an elastomer material. The compression spring element 25' is a compressible body which presses the guide pusher 30 into a safe position via the bearing pin 31 and holds it there.

In order to be able to erect the drinking stub 23', the user must push the guide slider 30 against the force of the compression spring element 25' into the position shown in fig. 11B. Here, the elastomeric compression spring element 25' is compressed. This position corresponds to the view of the first embodiment in fig. 7B. Accordingly, the drinking posture in which the drinking nozzle 23 'is erected is also just shown in fig. 8 in the case of the drinking cup lid 100'.

Fig. 12 finally shows the drinking cap 100 "according to the third embodiment in a perspective view, specifically in an unlocked position. The guide slide 30, the safety slide 40 and the base element 10 are also substantially unchanged here with respect to the first and second embodiments. The difference is an insert element with a drinking stub 23 ″, which in this embodiment does not have a spring element of a formed elastomer, but instead has a metallic compression spring element 50 ″ in the same position and function. The compression spring element 50 ″ presses the bearing pin 31, which is located in the oblong receptacle 18 in the base element 10, outward and thus automatically moves the guide pusher 30 back into the locking position, as long as the user no longer exerts pressure on the guide pusher 30.

The compression spring element 25' in the drinking cup lid 100' or the compression spring element 50 ″ in the drinking cup lid 100' on the one hand facilitates the closing process, since the user only has to press the guide slide 30 together with the drinking stub downward, without actively pulling the guide slide back into the locked position. On the other hand, the compression spring element arrests the upward bouncing of the guide slider 30 together with the drinking stub, since the user must place his finger on the guide slider 30 over a longer path in order to push the guide slider against the force of the compression spring element. The user thereby automatically weakens the erecting guide shoe. In the second embodiment of the drinking cup lid 100', the friction between the support pin 31 and the elastomeric compression spring element 25' additionally brakes the movement.
