Description

TECHNICAL AREA

The present invention provides a leak-proof liner for a drink container, a drink container, and a system comprising a leak-proof liner for a drink container and a drink container.

TECHNICAL BACKGROUND

Conventional drinking bottle systems are often designed in such a way that a small child can learn to drink. At the same time, these systems are equipped with various mechanisms that prevent the liquid in the drinking bottle from leaking out. These conventional systems usually have a drinking bottle neck provided with a screw thread, or a rim at the opening of the drinking bottle. Various inserts can be screwed into this screw thread, these inserts being designed in such a way that they prevent undesired leakage and allow the small child to take the liquid as desired. Other conventional systems rely on a specially designed insert being inserted into the neck of a drinking bottle in a cork-like manner by pushing (squeezing) or using a special retaining mechanism provided on the bottle itself. This insert can then be removed again by turning or pulling it out of the neck of the drinking bottle.

TECHNICAL PROBLEM

These conventional linkage mechanisms based on a screw mechanism or a cork mechanism are often cumbersome (difficult to insert into the drinking bottle and complicated to remove from it) and, due to the complicated design, awkward to clean.

SUMMARY

The present invention aims to solve at least one of the above problems of the known art, or to improve known solutions. The solutions are achieved by the subject matter of the independent claims. Further preferred embodiments are provided in the dependent claims.

According to one aspect of the present invention, there is provided a leakproof liner for a drinking container, comprising a ring having an open top end, a closed bottom end and a wall extending from the top end to the bottom end, and an attachment device, to attach the insert to the container, the attachment device being provided on an outer side of the wall, the attachment device comprising a first projection and a second projection, each projection respectively enclosing the wall, each projection comprising at least one channel and the projections so are arranged spaced apart that a gap is formed between the projections.

DETAILED DESCRIPTION

As already mentioned above, conventional drinking container systems have the problem that they are severely restricted in their handling due to the screw mechanisms used. As described below, the inventors have, among other things, developed an advantageous attachment mechanism by which an insert can be easily connected and disconnected from a drinking container for an extended period of time, but also easily removed again while the insert remains lightweight is to be cleaned. In this way, at least the disadvantages mentioned above are overcome or at least mitigated.

1A shows a cross section of a leak-proof insert 1 for a drinking container 3 and 1B shows a perspective view of the leakproof insert 1 according to an embodiment of a leakproof insert 1 for a drinking container 3 comprising a ring (the ring) comprising an open upper end 11, a closed lower end 12 and a wall 13 extending from the upper end 11 extends to the lower end 12, and (the leakproof insert further comprising) an attachment device 2 for attaching the insert 1 to the container 3, the attachment device 2 being provided on an outer side of the wall 13, the attachment device 2 comprising a first projection 21 and a second projection 22, each projection 21,22 respectively enclosing the wall 13, each projection comprising at least one channel 23,24, and the projections being spaced from each other such that a gap 25 is formed between the projections 21,22.

A drinking container can be a device that can hold, store and dispense a liquid. Furthermore, the liquid can be transported with the help of this device. Such a device may comprise a reservoir (belly, casing, shell) and an opening (neck), the reservoir carrying (or: receiving, containing, storing) the liquid and inserting the liquid into the reservoir via the opening (or: poured, recorded) can be. The liquid can usually also be removed from the reservoir (delivered from the reservoir) via the opening, or can leave the reservoir of the container at an outflow rate. Typical examples of a drinking container include a pot-shaped container, a bottle, a drinking bottle, a cup, a pot, a baby bottle, a jug, a mug.

An insert may be a device which can be inserted (inserted, inserted, attached, anchored, fastened, applied to the opening) into an opening of a container, for example the opening of the above drinking container. The insert can be designed in such a way that a liquid which is in the container is prevented from leaving the container (the reservoir of the container) at a high, undesired escape rate, or from leaking out of the container. The insert can furthermore be designed in such a way that a liquid which is stored in the container can leave the container or can be dispensed from the reservoir of the container at an exit rate which is lower than the exit rate without an insert. Typical examples of an insert include a cork, a cork with a hole, a bottle spout, a bottle scoop.

The property "spill-proof" can mean that the liner can prevent leakage of the liquid contained in the container, or accidental leakage of the liquid from the container to a small extent, corresponding to according to a very low outflow rate.

A ring may be a device that is a coherent, one-piece form. This comprises an annular, self-contained wall, the top and bottom of which may each be circular. Alternatively, the lower and/or upper end can have a geometric shape, which can be represented by a continuous line. The upper end can be open, which means that the area defined by the line representing the upper end is not filled with material. The bottom may be closed, meaning that the area defined by the line representing the bottom is not filled with material. The top can also be paraphrased as a concave top open end. The lower end can be described as convex. In other words, the ring itself can be described as a concave structure arched towards the center (downward). The resulting outside of the structure then forms the convex lower end of the structure and the concave top forms the concave upper end. The designations "upper end" and "lower end" are to be considered here as clarifying but not limiting to a specific geometric orientation in space. For example, the insert comprising the ring can be inserted into the drinking container with the lower, convex end first. The ring can also have at least one ventilation opening 14, preferably several ventilation openings. Such an opening can connect the side of the ring facing the inside of the container with the side facing away from the inside of the container. An air flow can thus take place between the interior of the container and the environment of the container through the opening. The dimensioning of the ventilation opening (width, length) can be configured differently.

An attachment device is configured to attach the insert to the container. In other words, it can be a device that allows, facilitates or reinforces the attachment (attachment to, insertion into, anchoring to) of the insert to the container.

A protrusion may be characterized as extending into space as a volume based on a geometric shape from the wall of the ring. The contact surface between the projection and the wall of the ring can be referred to as the base surface, bearing surface, attachment surface, connection surface. For example, a projection could be a geometric shape, for example a cuboid, which rests with one of its sides on (the contact surface) the wall, or is attached to the wall or is connected to the wall. As shown, the volume could also result from a triangular area as the base area. Alternatively, a protrusion can also be referred to as a protuberance (of the wall of the ring) of the insert. The projection could be provided or designed in the form of a circular ring on the outer wall of the ring of the insert. The second projection 22 may be convex, that is, configured with a rounded outer surface tapering towards the lower closed end.

Each protrusion (the first protrusion and the second protrusion) respectively encloses the wall of the ring of the insert. The enclosing here includes that (in each case) a projection runs along the wall (outer wall) of the ring of the insert such that a closed circle/ring or projection ring which surrounds (is arranged on) the outside of the ring of the insert , forms. This projection ring can be concentric with the ring of the insert.

Each protrusion further includes at least one channel. A channel can be an indentation in a protrusion. Here, a channel may allow liquid to enter the channel at an entry side (orifice) and exit the channel at an exit side. The entry side here could be the underside (the side facing the lower closed end of the ring) of a projection. The exit side here could be the top (the side facing the upper open end of the ring) of the projection.

By using a channel so designed, excessive leakage of a liquid can be prevented by the protrusion itself, while the specific configuration of the channel, such as diameter, length, depth, height, width, can design the passage of liquid. Furthermore, the channels of the projections can be matched to one another. This means that the exit side of a first channel (a first projection) is matched to the entrance side of a second channel (a second projection) such that the exit side and entrance side overlap at least a fraction. A channel can be arranged at different points of the projection. For example, it may form a tunnel inside the projection, or be formed on the outside (the side opposite the wall of the ring) of the projection.

Furthermore, the projections are arranged spaced apart that a gap between cal the projections arises. In other words, the protrusions can be spaced along the height of the wall (the line perpendicular to the lower end, extending towards the upper end) - in other words: not along the winding direction of the ring of the insert . This distance can be chosen such that the recess (gap) is formed between the two projections. The gap itself then extends along the winding direction of the wall, or essentially perpendicular to the height of the wall.

The insert comprising the ring and the attachment device as described above can be provided as a homogeneous, one-piece fabrication (casting). In other words, the insert can be “cast in one piece”, which means that the insert, including the ring and the attachment device, can be made of the same material and can be manufactured using a 3D printing process or a casting process, for example.

Furthermore, the insert can have a removal unit 15 . This can be provided, for example, on the side of the lower closed end facing away from the interior of the container and enable a user to release the connection between the insert and the container by pulling on the removal unit, or to pull the insert out of the container.

Thanks to this solution, in particular due to the advantageous design of the projections and the gap in between, the leak-proof insert can be easily inserted into the drinking container and removed again. Furthermore, the advantageous provision of at least one channel per projection allows drinking from the drinking container. Meanwhile, if the drinking container is not being drunk from, the present solution will prevent it from leaking. Here, the insert, or the open upper end of the insert, can be designed in such a way that the insert (the open upper end) does not end with the upper end of the drinking container, but rests on this upper end of the drinking container. This can also be described as the insert with attachment being negative. As a result, the outflow of a liquid can be further reduced or prevented. Furthermore, the open upper end of the ring can be slightly concave. The outflow of a liquid can be further reduced by the slightly concave design. In particular, the insertion and removal of the insert from the container can also be simplified by a concave design of the ring. The use of a ventilation opening can reduce or control the suction resistance when a user (a child) removes liquid, since the negative pressure that occurs in the bottle can be reduced or evened out entirely. The configuration of the second projection as convex simplifies the insertion of the insert into the container and further enhances the anchorage of the insert in the container.

2A Figure 12 shows a perspective view of a leakproof liner and 2 B Figure 12 shows a top view of the leakproof insert according to one embodiment of the leakproof insert, wherein the first projection 21 and/or the second projection 22 (each) comprises a plurality of channels 231, 232, 241, 242, which run radially along the (respective) projection 21 , 22 are arranged, the channels preferably being arranged along the (respective) projection 21, 22 at equal distances from one another.

The channels can be designed in the same way. However, the channels can also differ from one another in terms of their design.

The channels can here be arranged radially, in other words in a straight line starting from the center point of the ring of the insert, in a respective projection. Expressed in angular coordinates, the channels could be formed along the azimuthal direction 7 in the respective projection, with the origin of the coordinate system being at the center of the ring of the insert. A large number of channels per projection means that a projection is provided with at least two channels, or at least two channels are each formed (designed) in a projection.

Equally spaced channels are when the azimuthal distance between two adjacent channels, 71, 72, does not change substantially for all of the plurality of channels. For example, the distance between four channels 231, 232, 233, 234 provided in a projection 21 could be in angular measure, 7, substantially 90 degrees, or one quarter of a full angle. Furthermore, for example, the angular distance between three channels provided in a projection 21 could be essentially 120 degrees, or one-third of a full angle. More generally, the spacing could be an nth fraction of a full angle (360 degrees) for n channels per protrusion.

For example, a tooth-like structure can be generated by the configuration of the plurality of channels, the ver between channels remaining parts of the projections each correspond to a "tooth" and the channels correspond to the "gaps" between those teeth.

Thanks to this solution, the exit rate of the liquid from the drinking container can be advantageously controlled. This is because an increase in the number of channels (number of channels) per projection increases the flow volume which can be passed through the respective projection per unit of time.

3 12 shows a cross-section of a leakproof insert 1 according to a further embodiment, wherein a first diameter 211 of the first projection 21 is larger than a second diameter 221 of the second projection 22. FIG.

A diameter of a protrusion here describes the diameter of a circle substantially running along the outside edge (the part extending away from the inside of the ring) of a respective protrusion 21,22. The diameter can also be referred to as the distance between two opposing, outer (outer) edges of a projection surrounding the ring, facing away from the center of the ring.

In other words, the first projection 21 can overlap the second projection 22, or extend further away from the center of the ring than the second projection.

For example, the diameter of the first protrusion can be in the range of 62 to 66 millimeters. For example, the diameter of the second projection can be in the range of 57 to 61 millimeters.

More specifically, the diameter of the first protrusion can be substantially 65 millimeters and the diameter of the second protrusion can be 59 millimeters.

Thanks to the smaller diameter of the second projection provided by this solution, the insert can be inserted into and removed from the opening of the drinking container in a very easy, intuitive way. At the same time, the first, larger diameter of the first projection efficiently prevents the entire insert from being inserted into the reservoir of the drinking container. This significantly improves the performance characteristics of the embodiment described here, especially compared to conventionally known inserts, for example based on screw mechanisms.

4 12 shows a cross-section of a leakproof insert according to a further embodiment of the wherein the distance 251 at which the first projection 21 and the second projection 22 are spaced apart has a value in the range of 2 to 4 millimeters, preferably in the range of 2.5 up to 3.5 millimeters.

The resulting gap formed between the two protrusions surrounds (encircles) the outside of the wall of the ring of the insert, with its width (substantially parallel to the wall of the ring), which is substantially parallel to the height of the ring, divided by the gap is set at 2 to 4 millimeters, preferably 2.5 to 3.5 millimeters. In particular, the distance can be substantially 3 millimeters.

This solution advantageously allows the retention properties of the insert to be adapted to the typical thickness of a fastening ring attached to the opening of the drinking container. As a result, the insert is additionally fixed, an unfavorable "snaking" of the insert or the mobility of the insert is reduced, and thus also, since there is less free space available for liquid to penetrate, the leakage security is increased.

5 Fig. 12 shows a cross section of a leakproof insert according to another embodiment, wherein the first projection 21 and the second projection 22 are configured such that a part 31 of the container 3 inserted into the gap can be fixed to the leakproof insert.

The part of the container can be a component (e.g. in a fastening ring) of the container adapted to the distance at which the first projection and the second projection are arranged spaced apart from one another, or the width/height of the gap. The dimensions (thickness, width, height) of the part of the container and the gap can be matched. For example, a width of the part can essentially correspond to the width of the gap. The width of the part here can be smaller than the width of the gap. For example, the gap can have a width which is defined (dimensioned) by the above-mentioned distance as 3 millimeters in width. The part can then have a width perpendicular to its longitudinal axis (parallel to the distance between the protrusions) of 2.5 millimeters.

The part can be fixed to the leakproof insert by inserting into the gap. The part of the container can here be inserted into the gap along its longitudinal axis. This can be done, for example, by inserting the insert into the container take place. Furthermore, the part can be inserted along the longitudinal axis of the gap. The longitudinal axis of the gap may be parallel to the wall of the ring of the liner. In other words, the part can be attached, clamped, inserted, pinned, or retained on the insert. In other words, the dimensions (width, height, thickness) of the part and the gap are matched so that the part fits into the gap but is restricted in its movement there. In particular, movement of the part along the longitudinal axis of the gap may be possible, while the part can no longer be moved substantially perpendicular to the longitudinal axis of the gap.

With this solution, the insert can advantageously be attached to the container (drinking container) with an increased fastening effect and thus security.

6A Figure 12 shows a perspective view of a leakproof liner and 6B Figure 12 shows an illustration of a leakproof liner according to a further embodiment, wherein a first projection body 212 and/or a second projection body 222 each comprises a volume defined by a surface 213, 223 is formed.

The body of a protrusion may be the shape of the volume assumed by the protrusion. For example, the in 6B be the body of the first projection 21 obtained by a triangle rotating around the ring 13 shape of the volume.

The volume formed by a surface (e.g. the triangle 213) running along a circle surrounding the wall can be described as a solid of revolution. A solid of revolution can be formed by rotating a surface that rotates about an axis of rotation. The axis of rotation can be perpendicular to the circle surrounding the wall. The surface can run along the circle or rotate around the axis of rotation for a given radius. The radius can also vary with the azimuthal angle. The axis of rotation may pass through the center of the ring of the insert and be perpendicular to the closed lower end of the ring.

With this advantageous configuration, an even distribution of forces within the first and/or second projection can be achieved during and during the attachment of the insert in the drinking container. This advantageously increases the service life and usability of the insert.

7 Figure 13 is an illustration of a leakproof liner according to another embodiment wherein surface 213 is defined by a first line 2133 corresponding to wall 13, a second line 2132 extending away from wall 13 and a third line 2131 corresponding to the first line 2133 and the second line 2132 connects is formed.

The area can be formed by three lines, the first, the second and the third line. These lines can be connected to each other at nodes. By connecting the lines, a closed area can be defined. More or less than three lines can also be used to define the area. In particular, the lines connected to each other at the nodes can be considered as one line. The lines can define the perimeter of the area.

The first line (first stretch) corresponding to the wall of the ring of the insert may be substantially parallel to that wall. The first line may correspond to the point of contact, or line of intersection, of the surface defining the body of a protrusion as described above with the ring. The first line connects two boundary points by which it is bounded, respectively a start point and an end point.

The second line (second segment), which extends away from the wall, connects two delimiting points by which it is delimited, respectively a starting point and an ending point. Either the starting point or the ending point of the second line can be connected to the starting point or the ending point of the first line as the junction of the two lines. The boundary point not connected to the first line can lie in a plane perpendicular to the ring of the insert.

The third line (third stretch) connecting the first line and the second line connects two boundary points by which it is bounded, respectively a starting point and an ending point. Either the starting point or the ending point of the third line can be connected via the starting point or the ending point of the first line as a node. The boundary point of the third line that is not connected to the first line can be connected to the one boundary point of the second line as a node.

This solution allows the projections located on the wall to be shaped in a particularly easy-to-manufacture, flexible manner.

In another embodiment of the leakproof liner, the liner 1 includes silicone or rubber.

Here, silicone can have the property that it does not react with food, that it does not undergo any structural changes at low temperatures (for example: below zero degrees Celsius) and high temperatures (for example: one hundred degrees Celsius), that when it is used as an insert material no hazardous by-products that could adversely affect the health of an end user are formed. Other examples are food safe, or non-toxic, or food safe, or medical grade silicone.

Silicone can have a specific degree of hardness as a measure of the resistance that the silicone offers to indentation. For example, the silicone can take on one of the hardness grades shown in the table. The silicone can be a soft, or medium-soft, or medium-hard silicone. This hardness (the degree of hardness) can also be expressed in the so-called "Shore" scale (e.g. the Shore scale A and/or the Shore scale D). The silicone used as the material for the insert can have a hardness in a range from 30 to 60 Shore A. The silicone used for the insert can preferably have a hardness in a range from 30 to 50 Shore A. The silicone used for the insert can preferably have a hardness in a range from 40 to 50 Shore A. Furthermore, the silicone used for the insert can preferably have a hardness of essentially 70 Shore A.

In other words, the insert can include, contain, contain silicone. Alternatively, the insert (only, solely) consist of silicone.

The hardness of the various components of the insert, as well as the other devices described herein (specifically: the container), may vary between these components. For example, the ring of the insert can have a higher hardness than the projections.

The container described below can also contain silicone, for example, and can also have a hardness of 50 Shore D, for example. The cover described below can also contain silicone, for example, and have a hardness of 70 Shore A or a value in the range from 10 to 15 Shore D, for example. The holding device described below can also contain silicone, for example, and have a hardness of 60 Shore D.

However, the above should not be taken in a limiting sense. Rather, other materials with a corresponding degree of softness, degree of hardness, or a corresponding biological usability (food safety, food safety) could also be used. An example of such an alternative material is natural rubber.

This solution makes it possible to obtain an insert that can be attached to the drinking container (to be inserted into the drinking container) in a particularly flexible manner. The use of silicone, which can, among other things, assume the degrees of hardness described, allows the insert to be inserted and removed (“pulled out”) more easily into/from the drinking container, since the softer projections can flexibly yield to the pressure generated during insertion/removal.

8A shows a perspective view of a drinking container with an opening comprising a fastening ring according to a further embodiment and 8B shows a plan view of the fastening ring according to the embodiment, the drinking container with an opening comprising a fastening ring 5, which extends in a direction essentially parallel to the opening 4, the fastening ring 5 having at least one indentation 51, preferably a plurality evenly spaced indentations 51, 52, 53, 54 includes.

The mounting ring may be an integral part of the drink reservoir, or it may be a device attached to the drink reservoir, capped onto the drink reservoir, or screwed into the drink reservoir. The attachment ring may be configured to be linked (connected) to the insert described above. In other words, the fixing ring can be designed to be inserted into the gap formed by spacing the two protrusions. This can be accomplished, for example, by inserting the insert, lower closed end first, into the opening and through the mounting ring into the container.

The fastening ring can also be part of a holding device briefly described below, the holding device comprising at least one and preferably two gripping arms and being permanently fastened in the container, for example by gluing. A protuberance (tooth) can also be attached to the inside (the wall) of the opening of the container, for example above the fastening ring. For example, several of these protuberances can preferably be radial and be attached (provided) evenly spaced.

The attachment ring extends in a direction that is substantially parallel to the opening of the drinking container. In other words, the fastening ring is designed in such a way that it extends from the upper end of the opening of the drinking container into the interior of the drinking container. In other words, the attachment ring extends in a plane (or: in a plane) defined by the opening of the drinking container towards the center of the drinking container.

The mounting ring includes at least one indentation, preferably a plurality of evenly spaced indentations. The mounting ring can be described as an annular disk with a certain thickness. An indentation can then be described as a protuberance extending in the direction of the ring disk center (middle point of the ring disk). Alternatively, the indentation can be described as a notch in the washer. This indentation can be described as engaging the mounting ring radially from the center point of the washer.

The plurality of indentations can be evenly spaced. In other words, the indentations 51, 52, 53, 54 can be spaced along the inner edge of the fastening ring 5 such that the distance db1, db2 between each two adjacent indentations 53, 54 of the plurality of indentations is essentially the same. In other words, the mounting ring may be configured such that when the mounting ring is described in terms of an azimuthal angle (measured in angle db), the angular distance between any two adjacent indentations within the plurality of indentations remains substantially constant.

This solution makes it possible to obtain a drinking container that is advantageously adapted for use with an insert. The fastening ring initially allows the insert to be fastened in the drinking container. Furthermore, the indentations allow a liquid to flow through them, while the remaining parts of the fastening ring protruding into the interior enable the insert to be secured in the drinking container in a durable, permanent, and vibration-proof manner.

9 a cross section of the drinking container and the leakproof insert of a system according to a further embodiment comprising the drinking container 3 and the leakproof insert 1, wherein a diameter 6 of the fastening ring 5 is smaller than a first diameter 61 of the first projection 21 of the leakproof insert 1 and smaller than a second diameter 62 of the second projection 22 of the leakproof insert 1 is.

The concept of the diameters of the projections and the diameter of the fastening ring has already been described in the above embodiments and is also applicable here.

The diameter of the fastening ring can range from 45 to 59 millimeters. It can preferably assume a value in the range from 50 to 55 millimeters. Specifically, it can have a value of 51, 52, or 53 millimeters.

The first diameter of the first protrusion can have a value in the range of 60 to 70 millimeters. It can preferably assume a value in the range from 62 to 66 millimeters. Specifically, it can have a value of 64 millimeters.

The second diameter of the second projection can have a value in the range of 55 to 65 millimeters. It can preferably assume a value in the range from 57 to 61 millimeters. In particular, it can have a value of 59 millimeters.

This solution provides a system that has projections and a fastening ring that are so advantageously matched to one another in terms of their dimensions that a simple holding mechanism is created with which the insert can be fastened in the drinking container. Efficient leakage protection secured against vibrations can thus be achieved, while the further design of the insert enables the efficient removal of liquid from the drinking container, in accordance with a consumer request.

More examples are in the 10 until 17 shown.

The 10A shows a side view of the drinking container 3. 10B shows a bottom view of the drinking container 3. 10C shows another view of the drinking container 3. The dimensions that can be taken from the drawing are given in millimeters. For example, the value means 85.14 in 10B that the drinking container can have a diameter of 85.14 millimeters.

The 11A until 11E show representations of a lid for the drinking container. Here, too, the dimensions can be taken from the drawings given in millimeters. For example, the number 46.21 means that the radius of the lid (half the diameter) can be 46.21 millimeters.

As already described, the insert represents a hitherto unknown possibility for children to learn to drink while preventing the liquid from spilling or the drinking container from leaking. Well-known models have a twisted bottleneck, or a screw cap-based connection mechanism and an insert with a textured surface. Thus, these known models allow an adjusted liquid flow and drinking without spilling the liquid. Some of the models have a lid. The problem with these bottle models is that they continue to leak when dropped or thrown on the ground. Another problem is that they are made of plastic (e.g. PVC). The use of materials other than plastic can be beneficial from a health perspective.

In comparison, the insert described greatly reduces leakage from a container.

Furthermore, food-safe silicone can be used as the material for the system described. Food grade silicone can be silicone that has not had any chemicals or additives added. This makes the product free of toxins and child-friendly. Food grade silicone can be toxin free. The use of food-grade silicone allows the container and insert, as well as the other parts made from food-grade silicone, to be washed in a dishwasher or exposed to medium temperatures. Food grade silicone is also less odour, more durable and more hygienic than plastic. This means that a drinking bottle made of food-safe silicone (the container and insert) can be used longer than conventional, plastic-based bottles, which makes the drinking bottle described here even more environmentally friendly. Food-safe silicone has a wide range of advantages. The following are a few: light weight, heat resistant (dishwasher safe), oven safe, odorless, non-toxic (it contains no latex, no phthalates, lead, it is BPA-free), it is structurally stable (no cracking, breaking, etc.) , it is durable, hygienic, marine safe, food safe, and environmentally friendly.

The hardness of the described parts of the container and insert system can vary from one another.

In order for a child to drink from the container and insert, the parent must remove the insert simply remove it from the container, or: be able to pull (“easy pull”), fill the container (the bottle) and insert the insert back into the container in a simple manner (“easy push”). Then the child can drink. A cover, for example the cover shown, can be provided for transport. This can be soft and easy to use, thereby at the same time being strong and not easily removable by itself. The lid can also be removed by a child.

The rim may have a pressure-sensitive touch-flow feature that regulates the flow of liquid through the infant's sucking. The bottle head and insert can be ergonomically designed so that the lips and tongue assume a natural drinking position. By applying a light, natural pressure to the top of the liner, or the end of the bottle (the drink container), the rim between the liner and bottle opens (the rim of the liner rises), allowing liquid flow. This can still be made possible by slightly raising the inside of the rim of the bottle.

Compared to known solutions, the present invention differs primarily in the use and the holding device. Here, the combination of the tooth-like design of the holding device (also known as “double tooth system”) and a slightly protruding protuberance in the bottle (e.g. corresponding to the fastening ring described above) can allow the insert to be fastened with little pressure. The center of gravity of the double tooth system and thus the stability of the insert can also be medium to low. This can give the insert increased hardness despite being made of a soft material. Also, a rounded configuration of the underside of the insert can allow the insert to be easily inserted into the bottle, while the upper teeth (corresponding to the first, upper projection of the holder) prevent the insert from slipping or being pushed into the bottle.

The attachment mechanism in combination with the material properties allows liquid to spill into the top of the bottle. This means that less liquid collects above the teeth. The bottle thus becomes more leak-proof and drip-proof when shaken or bumped compared to known solutions. Furthermore, the insert with the bottle ends in a negative version. This creates a small amount of pressure when inserting the insert into the bottle (drinking container). Due to the simplified shape (no hidden parts) of the invention described, the parts can be cleaned easily and quickly. Food-safe silicone simplifies the cleaning of the indentations, gaps, gaps or indentations that occur in the insert.

The tooth-like structure creates a system in which both pressure mechanisms and suction mechanisms are possible and complement each other, making drinking easier. The amount of discharge can be influenced by the flow rate of the indentations between the teeth (corresponding to the channels in the protrusions), which prevents uncontrolled liquid discharge. With different suction intensities, the child can continue to regulate the amount of liquid.
