The present disclosure relates generally to the technical field of containers and, more particularly, to closure elements for use with paper cups for beverages or granular substances.
Containers used for beverages and granular substances, i.e. liquid or semi-liquid foodstuff, come in all shapes and sizes. Many containers are made of plastic materials and are intended for single use only, this may be problematic from an environmental perspective. Some common containers for beverages are entirely made on non-degradable plastic, other containers consist of a paper cup and a plastic lid.
Many takeaway cups available in prior art have lids attaching to a rim extending around the top of the cup. Generally, these cups are made from thin paper or plastic and are quite unstable and spillage of the beverage is common. When attaching the lid, it may sometimes be hard to know if the lid has been placed correctly over the rim, which can lead to spilling of the beverage. Further, if the cup and lid are hit, jolted or dropped, a lid attached by fastening to a rim can easily be displaced, as such lid commonly has parts protruding beyond the cup, causing spillage.
In case a hot beverage is served in a takeaway cup it may sometimes be too hot to hold. Many cafes and restaurants have therefore started to serve in double cups, where an extra cup encloses the cup holding the beverage to provide further insulation. However, the second cup is not connected to the first cup and the first cup can easily slide around inside the second cup causing spilling and making the construction harder to handle.
There is thus a need in the field to provide new kinds of container for both beverages and granular substances that at least partially remove some of the problems mentioned above.
The inventor has reached the insight that there is a need for a new type of closure element or lid that can be used with both existing cups or supplied with a dedicated cup to create a container for beverages or granular substances, such that the container can be effectively sealed in order to solve some of the problems above. The inventor has reached the insight that a closure element attaching to the cup on the inside of the cup may be more effective that the lids available today. Further, the inventor has reached the insight that there is a need for a closure element that can be used with takeaway cups already available and on the market, for solving common problems thereof. Further, the inventor has reached the insight that a closure element suitable for a container comprising more than one cup is needed in the field since two cups and the air between the two cups provide a good protection against heat.
Air is a good insulator and materials containing air are often used as thermal insulators in for example houses and buildings. Providing some aspects of a beverage container which uses air to insulate the beverage is both advantageous in that the beverage is kept at the preferred temperature longer and in that a user of the beverage container does not get burned if the content is hot.
More and more sustainable solutions for reducing plastic pollution are becoming available to the market. Molding paper pulp, fiber-materials, is a standard way of making containers, trays, and other types of packaging. Generally, the steps are as follows: a mold is made to be a mirror image of the finished paper product; holes are drilled through the mold and a screen attached to its surface; the mold is immersed into paper pulp; a vacuum is drawn through the holes when the mold is immersed in the paper pulp so that a layer of paper pulp sticks to the mold, the screen prevents pulp from clogging the holes. The mold is removed, and the paper pulp stuck to the side of the mold is removed and dried, a paper product has been created. Depending on the type of paper product different techniques may be used for removing the product from the mold. In what is known as “wet” manufacturing a transfer mold mates with the fiber product and moves the formed “wet part” to a hot press which compresses and dries the fiber material to increase density and to provide a smooth external surface finish.
Other ways of molding paper pulp are available. For example, by pressing the material between a female and male mold water can be drained from the material and a paper product with a wanted shape may be created.
Paper materials, such as fiber-based products, are recyclable, biodegradable, compostable and do not end up in the oceans in the same capacity as plastics. Therefore, they are preferable to be used as an alternative to many plastic products available today. Take-away cups or mugs are often made from paper material, however commonly the lids are made of plastic. It is therefore a further object to provide products made without non-degradable material, or at least with a minimal amount of non-degradable material, without influencing other factors, such as providing a container with good integrity and ability to hold a liquid safely.
Paper materials are advantageous over plastic products in many aspects. However, beverage containers made from paper materials may need some sort of inner lining or coating depending on the beverage to be served and the time the beverage is to be kept inside the container. This may for example be some sort of coating along the inner surface of the container that is water impermeable. The coating may be made from many different materials such as cellulose-based materials or plastics, preferably a biodegradable material.
When serving hot beverages in paper take-away cups, the cups are often too warm to hold comfortably by the user. Some cafés are handing out hot beverages in a double cup, i.e. one cup placed within another cup to give some sort of insulation to the user. However, the lid is placed only on the cup containing the beverage. This may create an unstable construction where the cups are moving in relation to one another. Further, a single take-away cup is not very stable or rigid in itself which increases the risk of spilling the beverage.
The present disclosure seeks to provide aspects of a container which overcome at least some of the above-mentioned drawbacks. More specifically, the present disclosure aims at providing a closure element adapted for use with a cup to form a container for beverages or granular substances that is stable and provides a pleasant experience for the user.
In a first aspect of the present disclosure, there is provided a closure element adapted for use with a cup having a top opening with a first area A1 in a cross-sectional plane perpendicular to an axis A. The closure element and cup are adapted to form a container when combined, with the container extending along the same axis A and configured to hold a beverage or a granular substance. The closure element comprises a sealing portion with a second area A2 in a cross-sectional plane perpendicular to the axis A, wherein the second area A2 is essentially equal to the first area A1. The sealing portion may be a sealing plate, but may also have other shapes. The closure element further comprises an annular sealing wall extending around the sealing portion, the annular sealing wall is tilted with an angle alpha of between 2-8 degrees in relation the axis A and intended to be in contact with an inside surface of an annular inner wall of the cup to seal the container. The closure element further comprises a spout configured to deliver the beverage or granular substance to a user. The closure element is configured to be pressed into the cup so that the annular sealing wall engages the inside surface of the annular inner wall of the cup to form a tight seal between the closure element and the cup. The closure element is made of cellulose-based paper material or fiber-based paper material.
Thus, there is provided closure element adapted for use with a cup to form a container with a first function of holding a beverage or granular substance and tightly sealing the container with the closure element by engaging the inside of the cup. The closure element is advantageous in that it provides a novel and inventive way of sealing a container. Further, it may be used with a wide range of known paper cups. Prior art containers closed with a lid attaching to a rim extending around the container may be hard to close. Such lids must be exactly adapted to the rim shape to be able to attach. Further, when attaching the lid, it may be difficult to understand when the lid is properly attached which may lead to spillage. The present invention is advantageous in that a user can very easily see when the container is closed and when the closure element has been placed properly.
Notably, the closure element disclosed herein may advantageously be used with a wide range of common cups, as the shape with an outer annular surface will provide the possibility to fit into most commonly marketed cups having an angled inner surface. A cup need not have the exact size opening matching the closure device circumference, as a closure device might either be pressed down into and past an opening of a cup, or in some cases, only be party inserted into an opening, and still function to seal the container. This makes it easier for users to attach the closure device to the cup, and allows for some margins of differences in size and the exact manner of pressing the closure device without affecting effective sealing. However, a closure device may of course be provided in a number of different sizes, to cover a wider range of cup sizes. Further, the shape and manner of sealing also makes the closure device's sealing function independent of if a cup has a protruding outer rim, or the shape of a rim.
According to a further aspect, there is provided a container configured to hold a beverage or granular substance and extending along an axis A, wherein the container comprises a first cup made of cellulose-based paper material or fiber-based paper material and comprising an opening with a first area A1, and a closure element as described herein. The cup has with an inner annular wall tilted at the same angle alpha in relation to the axis A as the annular wall of the closure device.
According to another aspect, a container may further comprise a second cup configured to at least partially enclose the first cup. The present aspect is advantageous in that it provides a lot more structural integrity for the container making it more stable. Further, when the closure element is pressed into the first cup, the first cup will be pressed outwards towards the second cup. This will ensure that the first cup and second cup are engaged and held together, which will both add structural integrity and insulation for a user, for example, in case the beverage served is hot. It is envisioned that the cups may be readily made cups available at many different venues and the closure element is provided for allowing a new and practical way of sealing the cups.
In addition to arranging an outer annular wall of a closure device as disclosed herein such that it will seal against an inner wall of a cup, the specified angle of the annular wall and the closure device being made of cellulose-based paper material or fiber-based paper material act together to provide an extremely tight seal as will be detailed further below.
The angle alpha, i.e. the angle of the annular sealing wall, is between 2-8 degrees, and more preferably between 4-6 degrees. This is advantageous in that in that if the angle alpha is too big, the closure element will not seal the container as effectively. If the angle is between 2-8 degrees the closure element can be pressed into the opening of most common cups and a tight seal will be achieved. More preferably, if the alpha angle is between 4-6 degrees, this will help achieve an even tighter seal.
According to another aspect, the closure element further comprises a removable and attachable lid element arranged to cover the spout. The lid element and spout are adapted to seal the container when the lid element is arranged to cover said spout, such that spilling is prevented. The present aspect is advantageous in that a lid element can be used to reseal the spout. In some aspects the spout may have a permeable surface pierceable by for example a straw. However, in other aspects having a lid element that may reseal the container may be advantageous. It is also envisioned that both a lid element and a permeable surface may be used in certain aspects, the lid element may then be constructed in a way that allows it to be used to pierce the permeable surface.
According to another aspect, the spout comprises a first set of threads extending around the spout, and the lid element comprises a second set of threads and the lid element is configured to be screwed onto the spout. The present aspect is advantageous in that the lid element can be screwed onto the spout making it resealable and a user may more easily bring the container with them without spilling.
According to another aspect, the spout comprises a first protruding rim extending around the spout and the lid element comprises a first receiving recess configured to receive the protruding rim, and the lid element is configured to be pressed onto the spout. The present aspect is advantageous in that the container is resealable.
According to another aspect, the spout comprises a permeable surface configured to be pierced. The present aspect is advantageous in that it allows a user to easily reach the content of the container.
According to another aspect, the lid element comprises a spike configured to be used to pierce the permeable surface in order to allow a user to reach the beverage or granular substance. The present aspect is advantageous in that the user can easily open the container and reach the content.
According to another aspect, the closure element comprises a second protruding rim extending around the annular sealing wall, and the cup comprises a second receiving recess extending around the inner annular wall of the cup and configured to receive the second protruding rim when the closure element is pressed into the cup. The present aspect is advantageous in that the seal between the closure element and the cup will be further strengthened by the interaction between the protruding rim and receiving recess.
The closure device is made of a paper material. In aspects comprising a container with a cup and a closure device, the entire container, i.e. both closure element and cup, are preferably made of a paper material, more preferably the same paper material. Using paper material is advantageous in that the paper material is biodegradable and more environmentally friendly than plastic. It is further advantageous in that paper material can easily be made quite stiff or rigid which is preferable to flexible plastic cups. It is further advantageous in that a cup, or in certain aspects two cups made of a paper material pressed together provides an even stronger construction. With paper material it is meant any kind of paper material, cellulose-based material or fiber-based material that is recyclable and/or biodegradable. The paper material may be formed by different kinds of mixtures of fiber materials, recycled materials or other type of materials used in paper making.
According to another aspect, the paper material is formed from fiber-based slurry comprising a fiber base comprising at least 50% by weight of old corrugated container (OCC). In some aspects, the fiber-based slurry may further comprise a moisture barrier, and/or an oil barrier. The moisture barrier and the oil barrier may be in a range of about 1%-4% by weight respectively. The present aspect is advantageous in that OCC is a recycled material which further decreases the environmental footprint of the product.
According to another aspect, the paper material is formed from a fiber-based slurry comprising a fiber base comprising at least 10% softwood (SW). In some aspects, the fiber-based slurry may further comprise a moisture barrier, and/or an oil barrier. The moisture barrier and the oil barrier may be in a range of about 1%-4% by weight respectively. The present aspect is advantageous in that SW, for example bamboo or bagasse, is an environmentally preferable material to plastic. Further, a fiber-based slurry with the mentioned components creates a good mixture for a beverage container or bottle. The present aspect is further advantageous in that some SW-materials are the residues from other industries and is therefore material which does not drain the resources of the planet more than necessary but instead may help give the product a decreased environmental footprint.
According to another aspect, the fiber-based slurry further comprises a strength additive in a range of 1.5%-4% by weight. The present aspect is advantageous in that adding a strength additive makes the product, the bottle, more rigid in that the dry strength is improved. Further, other advantageous such as increases drainage and retention are features of adding a strength additive.
In aspects comprising a cup, at least an inside surface of the cup may comprise an impermeable coating layer. The present aspect may be advantageous in that it allows the container to hold a beverage for longer without affecting the container and or the beverage. The coating layer may be made from many different materials. It is further envisioned that an inside surface of the closure element may be lined with such an impermeable coating layer.
It is noted that other aspects using all possible combinations of features recited in the above described aspects may be envisaged. Thus, the present disclosure also relates to all possible combinations of features mentioned herein. Any aspect described herein may be combinable with other aspects also described herein, and the present disclosure relates to all combinations of features.
Exemplifying aspects will now be described in more detail, with reference to the following appended drawing:
a,b,c,d schematically illustrate various aspects of closure elements in accordance with aspects of the present disclosure.
As illustrated in the figures, the sizes of the elements and regions may be exaggerated for illustrative purposes and, thus, are provided to illustrate the general structures of the aspects.
Exemplifying aspects will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred aspects are shown. The invention may, however, be embodied in many different forms and should not be construed as limited to the aspects set forth herein; rather, these aspects are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.
It is understood that the shape of the aspects shown in the figures may be altered depending on the usage for the container. Different shapes are convenient in different situations, and the container may for example resemble the standard take-away cups or plastic bottles available today or they may not. The drawings are not intended to narrow the scope of protection for the shape of the container.
With reference to
In some aspects, a closure element 130 is provided, adapted for use with a cup to form a container, with a first function of holding a beverage or granular substance and tightly sealing the container with the closure element by engaging the inside of the cup. The closure element is advantageous in that it provides a novel and inventive way of sealing a container. Further, it may advantageously be used with a wide range of common cups, as the shape with an outer annular surface will provide the possibility to fit into most commonly marketed cups having an angled inner surface. A cup need not have the exact size opening matching the closure device circumference, as a closure device might either be pressed down into and past an opening of a cup, or in some cases, only be party inserted into an opening, and still function to seal the container. However, a closure device 130 may of course be provided in a number of different sizes, to cover a wider range of cup sizes. Further, the shape and manner of sealing also makes the closure device's sealing function independent of if a cup has a protruding outer rim, or the shape of a rim.
According to a further aspect, there is provided a container 100 configured to hold a beverage or granular substance and extending along an axis A, wherein the container 100 comprises a cup 110 comprising an opening with a first area A1 and a closure element 130 as described herein. The cup has with an inner annular wall 150 tilted at the same angle alpha in relation to the axis A as the annular sealing wall 150 of the closure device 130.
The container 100 is configured to hold a beverage or a granular substance. Notably, the phrase beverage or granular substance is meant to encompass any liquid, semi-liquid or granular foodstuff intended for ingestion by a user or used for the preparation of any type of food or beverage. The container 100 extends along an axis A. As mentioned, the cup 110 may be an already available take-away cup or it may be a specially made cup provided together with the closure element 130.
The cup 110 comprises an opening 115 with a first area A1 in a cross-sectional plane perpendicular to an axis A. The opening may be circular so that the first area A1 corresponds to the area of a circle. The cup 110 is configured to hold the beverage or granular substance and may be filled via the opening 115. The cup 110 further comprises annular inner wall 120 tilted an angle alpha a in relation to the axis A.
The closure element 130 comprises a sealing portion 140 with a second area A2 in a cross-sectional plane perpendicular to the axis A, wherein the second area A2 is essentially equal to the first area A1. The sealing portion 140 is illustrated as a flat plate in the Figures, but may have any suitable shape for sealing the container. The sealing portion 140 may be a circular plate. Sealing portion 140 is intended to seal at or near the opening 115 in order to seal the container to hold the contents within the container.
The closure element 130 further comprises an annular sealing wall 150 extending around the sealing portion 140. The annular sealing wall 150 is tilted with the angle alpha a in relation to the axis A. The closure element 130 is configured to be pressed into the first cup 110 so that the annular sealing wall 150 engages the inner annular wall 120 causing the container 100 to be sealed.
In the Figures, the closure element is shown as having a sealing portion 140 with a second area A2, i.e. the area of the closure element 130 in a cross-sectional plane perpendicular to the axis A, equal to the area A1 of the opening of the cup, such that when combined, the top of the sealing portion 140 is exactly in line with the top of the cup. However, the second area A2 may be either equal to, slightly smaller than or slightly larger than the area A1 of the opening of the cup. If the second area A2 is slightly smaller than the area A1 of the opening of the cup, the closure element will seal the opening at a position slightly below the opening of the cup, as it may be pressed slightly further into the cup. Similarly, if the second area A2 is slightly larger than the area A1 of the opening of the cup, the closure element will seal the opening such that the cross-sectional plane perpendicular to the axis A in which the second area A2 is measured will end up somewhat above the opening of the cup. This makes it easier for a user to attach the closure element 130 to the cup 110, and allows for some margins of differences in cup sizes, without compromising effective sealing.
The container 100 further comprises a spout 160 configured to deliver the beverage or granular substance to a user and being arrange somewhere on the sealing portion 140. The spout may be of various sizes and shapes.
The angle alpha α is between 2-8 degrees. It may also be between 4-6 degrees.
The angle alpha α may be chosen depending on the material of the container 100 and depending on the friction that is created between the annular sealing wall 120 of the closure element 130 and the inner annular wall 150 of the cup 110. A too large angle alpha α is not preferable since the closure element 130 may fall out of the first cup 110 during use. An angle alpha α around 6 degrees is preferable. However, it may, as stated, be different angles for different aspects and materials that are preferable. The angle alpha α may for example be 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, or 8 degrees.
The closure device 130 is made of a paper material, preferably cellulose-based paper material or fiber-based paper material. In aspects comprising a container 100 with a cup 110 and a closure device 130, the entire container is preferably made of a paper material, more preferably the same paper material. In some aspects, only certain parts of the container may be made of a paper material. For example, the annular sealing wall of the closure element 130 is preferably made of paper material, while other parts of the closure element 130 may be other materials. In addition, the inner wall of a cup 110 may preferably be made of paper material, as the paper material provides a high friction surface, which increases the friction in sealing the closure element 130 against the cup 110. However, it is preferred that all or a majority of the materials in the closure element 130, and cup 110, when provided, are of a degradable and environmentally friendly material.
With paper material is meant any material that is made of fiber-based, cellulose-based materials or similar materials that are biodegradable and recyclable.
Closure element 130 and cup 110, when provided, may for example be made of a fiber-based material. For example, a fiber-based slurry can be pressed or shaped to form some sort of paper material, cardboard material, or other biodegradable material.
The paper material may be formed by a fiber-based slurry. Fiber-based products are biodegradable, compostable and do not end up in the oceans in the same capacity as plastics. Therefore, they are preferable to be used as an alternative to many plastic products available today. Further, using a fiber-based material results in a high friction surface, which enhances the seal between the annular sealing wall of the closure element and the cup.
In different aspect the parts of the container 100 may be formed by different types of fiber-based slurries. Here follow a few examples, however they are not seen as limiting and other materials and mixtures and proportions are also considered.
The paper material may be formed by a fiber-based slurry that may comprise at least 50% by weight of old corrugated container (OCC). Further, in some aspects, it may comprise a moisture barrier, and an oil barrier. The moisture barrier and the oil barrier may be in a range of about 1%-4% of weight respectively.
The paper material may be formed by a fiber-based slurry that may, in another aspect, comprise at least 10% softwood (SW). Further, in some aspects, it may comprise a moisture barrier, and an oil barrier. The moisture barrier and the oil barrier may be in a range of about 1%-4% of weight respectively.
The fiber-base slurry may also have a base fiber from any of the following groups: bagasse, bamboo, newsprint (NP). Other types of fiber materials are also available for forming the paper material.
The fiber-based slurry may also comprise a strength additive in a range of 1.5%-4% by weight. This may be added to enhance structural rigidity.
Molding paper pulp, fiber-materials, is a standard way of making containers, trays, and other types of packaging. Generally, the steps are as follows: A mold is made to be a mirror image of the finished paper product; Holes are drilled through the mold and a screen attached to its surface; The mold is immersed into paper pulp; A vacuum is drawn through the holes when the mold is immersed in the paper pulp so that a layer of paper pulp sticks to the mold, the screen prevents pulp from clogging the holes.
The mold is removed, and the paper pulp stuck to the side of the mold is removed and dried, a paper product has been created. Depending on the type of paper product different techniques may be used for removing the product from the mold. In what is known as “wet” manufacturing a transfer mold mates with the fiber product and moves the formed “wet part” to a hot press which compresses and dries the fiber material to increase density and to provide a smooth external surface finish. Notably, other molding techniques may be used to provide the desired shape and structural integrity.
Closure element 130 and cup 110, when provided, may be formed according to the above stated procedure by the fiber-based slurry and a vacuum former. They may be formed for example by a method containing the steps of providing a fiber-based slurry mixture. Immersing a mold including a wire mesh comprising a mirror image of parts of the beverage container to be formed. Then drawing a vacuum across the wire mesh to cause the fiber-based slurry to accumulate at a surface of the wire mesh. Then removing the mold from the fiber-base slurry mixture, removing molded parts from the surface of the wire mesh. Lastly pressing the molded parts in a hot press. However, other steps of standard vacuum forming may be incorporated into the method for achieving a functional closure element 130 or cup 110.
Closure element 130 and cup 110, when provided, may be formed in other ways as well. For example, a female and male mold of the closure element 130 or cup 110 may be constructed. A fiber-based slurry, or other suitable material, may be poured into the female mold. The male mold may then be used to press the material to the sides of the female mold creating the correct shape. The molds may be constructed so that the water within the material is drained away through a mesh in the female and male mold while pressing.
Other ways of forming the closure element 130 and cup 110, when provided, are also possible and the skilled man understands that different options are available. Depending on the part and depending on different features of the aspects different ways of forming the paper material may be preferable.
It may further be advantageous for the closure element 130, and cup 110, when provided, to comprise a water impermeable coating. The coating may be made of a plastic material and may be a thin sheet covering an inside of the closure element 130 or cup 110. The coating may be impermeable and allow for the beverage to be stored without penetrating the coating and reaching the walls of the closure element 130 or cup 110. The coating may be made from a plastic material or any other suitable material which is water impermeable, for example some cellulose-based materials. However, it is preferable that the coating be of a biodegradable material or at least have a low environmental footprint.
Depending on the beverage stored within the container 100 and the time the beverage is stored, the closure element 130 or cup 110 may comprise such a coating. Some beverages affect or damage paper-materials more than others, and therefore a coating may be needed for certain beverages. Further, depending on the storage time of the beverage within the container 100 a coating may be preferable. The longer a beverage is kept within the container 100 the higher the risk that the closure element 130 or cup 110 is affected by the beverage. Therefore, a coating may be preferable for closure elements 130 or cups 110 configured to store a beverage a longer period. The coating may have different thicknesses depending on the material it is made from and depending on the beverage to be stored.
Further, it is also possible that parts of the beverage container comprise other materials. For example, the closure element 130 and/or cup 110 may comprise plastic, silicon, or a metal in certain parts. It may be advantageous in making some parts of the closure element 130 and/or cup 110 from material that is more durable and suitable for long time use and some parts of the closure element 130 and/or cup 110 of more environmentally friendly material such as fiber-based materials.
With reference to
The closure element 130 and cup 110 correspond to the closure element 130 and cup 110 of
The combination of the arrangement of an outer annular sealing wall of a closure device 130, the specified angle of the annular sealing wall and the closure device being made of cellulose-based paper material or fiber-based paper material together act to provide an extremely tight seal. The angle alpha of 2-8 degrees in itself results in a good seal between the annular sealing wall 150 of the closure element 130 and the annular inner wall of the cup 110, as this angle matches most commonly provided beverage cups. Furthermore, having the closure element 130 made of cellulose-based paper material or fiber-based paper material provides a surface of the annular sealing wall with an at least slightly rough surface, which provides high friction when pressed against the inner wall of a cup. Additionally, if one also attaches it to a cup similarly made of cellulose-based paper material or fiber-based paper material, this increases the friction even more. A tight seal is thus created when the closure element 130 is pressed into a cup, in some aspects even to a degree where it would be difficult, or take substantial force, for a user to remove the closure element 130 once attached to the cup.
The intended use of the closure element 130 is to seal the container tightly, and stay sealed over time, without the closure element 130 falling off or being removed. Thus, the closure element 130 is not primarily intended to be a lid for the user to remove once attached, e.g. for drinking the contents. Any filling of contents or drinking by the user is preferably done through the spout 160.
In some aspects, the closure element 130 further has a removable and attachable lid element 180 arranged to cover the spout 160, as will be further detailed in connection with
The container formed when closure element 130 is combined with, i.e. attached to by pressing into, a cup, is resistant to spilling and leaking, while still providing a user friendly container for filling and drinking beverages.
With reference to
In
The closure element 130 comprises a protruding rim 132 extending around the second annular wall 150. The cup 110 comprises a receiving recess 112 extending around the annular sealing wall 150 and being configured to receive the protruding rim 132 when the closure element 130 is pressed into the cup 110.
Upon pressing the closure element 130 into the first cup 110 a user will notice when the closure element 130 is correctly placed, when the protruding rim 132 and the receiving recess 112 are joined. The protruding rim 132 and the receiving recess 112 will also further help in sealing the container 100, allowing a better and more reliable user experience.
It is further envisioned that at least parts of the closure element 130 may have a contrasting color compared to the first cup 110 so that a user may be able to clearly see when the closure element 130 has been placed correctly inside the first cup 110.
