Description

CONTAINER Technical Field The present disclosure relates generally to the technical field of containers and, more particularly, to paper cups for beverages or granular substances.

Background Containers used for beverages and granular substances 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.

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, which can lead to spilling of the beverage. ln case a hot beverage is served in a takeaway cup it may sometimes be to 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 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.

Summary The inventor has reached the insight that there is a need for a container for beverages or granular substances that can be effectively sealed by a new type of lid in order to solve some of the problems above. The inventor has reached the insight that a lid attaching to the container from the inside of the container may be more effective that the lids available today. Further, the inventor has reached the insight that there is a need for a lid 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 lid 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 embodiments 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. ln 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.

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.

Take-away cups or mugs are often made from paper material. However, when serving hot beverages, 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 which increases the risk of spilling the beverage.

The present disclosure seeks to provide at least some embodiments of a container which overcome at least some of the above-mentioned drawbacks. More specifically, the present disclosure aims at providing a container for beverages or granular substances that is stable and provides a pleasant experience for the user. ln a first aspect of the present disclosure, there is provided a container configured to hold a beverage or a granular substance and extending along an axis A. The container comprises a first cup comprising an opening with a first area A1. The first cup is configured to hold the beverage or granular substance. The first cup further comprises a first annular wall tilted an angle alpha in relation the axis A. The container further comprises a closure element. The closure element comprises a sealing plate with a second area A2 equal to the first area A1. The closure element further comprises a second annular wall extending around the sealing plate, the second annularwall is tilted with the angle alpha in relation the axis A. The closure element further comprises a spout configured to deliver the beverage or granular substance to a user and arranged on the sealing plate. The closure element is configured to be pressed into the first cup so that the second annular wall engages the first annular wall and the container is sealed. ln a second aspect of the present disclosure, there is provided a method for filling a container comprising filling a first cup with a beverage or granular substance and pressing a closure element into an opening of the first cup so that an annular wall of the closure element engages an annular wall of the first cup.

Thus, there is provided a container and a method for filling a container with a first function of holding a beverage or granular substance and sealing or the container with a closure element that engages the inside of a first cup. The container is advantageous in that it provides a novel and inventive way of sealing a container. Prior art containers closed with a lid attaching to a rim extending around the container may be hard to close.

The closure element 130 is configured to be pressed into the first cup 110 so that the second annular wall 150 engages the first annular wall 120 causing the container 100 to be sealed.

The container 100 further comprises a spout 160 configured to deliver the beverage or granular substance to a user and being arrange on the sealing plate 140.

Figure 1 shows the closure element 130 not pressed into the first cup 110 and may represent how the container 100 is distributed. After filling the container 100 for the first time the closure element 130 may be pressed into the first cup 110 sealing it effectively.

The angle alpha oi may be between 2 - 8 degrees. lt may also be between 4 - 6 degrees. The angle alpha oi may be picked depending on the material of the container 100 and depending on the friction that is created between the first annular wall 120 and the second annular wall 150. A too large angle alpha oi is not preferable since the closure element 130 may fall out of the first cup 110 during use. An angle alpha oi around 6 degrees is preferable. However, it may, as stated, be different angles for different embodiments and materials that are preferable.

The container 100 may be made of a paper material. ln some embodiments only certain parts of the container may be made of a paper material.

With paper material is meant any material that is made of fiber-based, cellulose-based materials or similar materials that are biodegradable and 11 recyclable.

The parts of the container 100 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. ln different embodiment 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, 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 embodiment, comprise at least 10% softwood (SW). Further, 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. 12 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 dri||ed through the mold and a screen attached to its surface; The mold is immersed into paper pulp; A vacuum is drawn through the ho|es 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 ho|es.

The parts of the container 100 may be formed according to the above stated procedure by the fiber-based slurry and a vacuum former. lt may be formed for example by a method containing the steps of providing a fiber-based slurry mixture. lmmersing 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 container 100 and corresponding container parts.

The different parts of the container may be formed in other ways as well. For example, a female and male mold of the first cup 110 may be constructed. A 13 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 container 100 and the different parts of the container 100 are also possible and the skilled man understands that different options are available. Depending on the part and depending on different features of the embodiments different ways of forming the paper material may be preferable. lt may further be advantageous for the container 100 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 container 100. The coating may be impermeable and allow for the beverage to be stored without penetrating the coating and reaching the walls of the container 100. The coating may be made from a plastic material or any other suitable material which is water impermeable, for example some cellulose-based materials.

Depending on the beverage stored within the container 100 and the time the beverage is stored the container 100 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 container 100 is affected be the beverage. Therefore, a coating may be preferable for containers 100 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 are made of other materials. For example, the closure element 130 may be made of 14 plastic, silicon, or a metal. The closure element 130 may then be used multiple times and withs different containers 100 in case of the original container 100 being damaged. lt may be advantageous in making some parts of the container 100 from material that is more durable and suitable for long time use and some parts of the container 100 of more environmentally friendly material such as fiber-based materials.

With reference to Figure 2 there is disclosed an illustration of a container 100 according to an embodiment of the invention.
