Definitions
- the present invention relates to a method of producing bottle caps for use with a bottle having a threaded neck opening into the bottle.
- Today's bottle caps are made of plastic material, which after use commonly end up as a waste material.
- the invention preferably seeks to mitigate, alleviate or eliminate one or more of the above mentioned disadvantages singly or in any combination.
- a method is provided of producing bottle caps for use with a bottle having a threaded neck opening into the bottle, where the bottle cap is produced from cellulose fibers, the method comprising:
- a very simple method is provided that is capable of producing recyclable bottle caps in an efficient manner at a mass product level, where the step of providing the cap-like wet moulded products until the bottle caps have been produced takes only several seconds.
- cap-like wet moulded products may according to the present invention be understodd a product, e.g. cylindrical shaped, that is open in one end and closed in the other end.
- the inner shape may have a cylindrical shape.
- the outer shape should not be construed as being limited to a cylindrical shaped, the outer shape can have any kind of shape, e.g. rectangular, triangular etc..
- the cellulose fibers is a plant based cellulose, where the plant based cellulose may in one embodiment be bagasse produced from sugarcane. Bagasse is 100% biodegradable and compostable and a bi product of sugar cane fiber which is left after the juice has been extracted from the sugar cane, but hundred thousands of tons of bagasse remains to be used yearly.
- bagasse has become an inexpensive product and thus the value of bagasse may be increased significantly and therefore a favorable option is provided for producing lids for containers using bagasse.
- bagasse is annually renewable as opposed to trees that take 7 top 20 years to grow and is biodegradable as trees.
- the female die is heated to a temperature between 160°C to 220°C.
- the elongated structure is heated to a temperature between 160°C to 220°C.
- the elongated structures with the external threads may comprise a cylindrical rod incised with one or more helical or advancing spiral threads, as a lead screw or worm screw.
- inner threads are defined on an inner side of the moulded products, and when un-screwing the elongated structures with the external threads out of the moulded products it is preferred that the elongated structures with the external threads follow these inner threads, i.e. it is preferred that the pulling force that is applied when moving the elongated structures with the external threads out of the moulded products is such that the elongated structures with the external threads follow the same inner threads as defined when screwing the threads into the moulded products.
- the method further comprises halting the elongated structures with the external threads upon reaching the pre-defined position for a pre-defined time period. This may be of advantage if the time it takes to screw and un-screw the elongated structures with the external threads is not sufficient to fully dry the cap-like moulded products in the heated female die.
- the time of screwing and un-screwing the elongated structures with the external threads is selected such that cap-like moulded products are fully dried.
- the un-screwing process may be operated at a slower mode than the screwing process, so as to ensure that after completing un-screwing the elongated structures with the external threads out of the moulded products they are fully dry.
- At least one of the elongated structures with the external threads and the plurality of cavities in the female mould comprise plurality of ventilation openings adapted to provide access for the moisture in the wet moulded products. A more efficient drying of the cap-like moulded products is provided.
- the pre-defined position is a position adjacent to the bottom sections of the plurality of cavities.
- the step of providing the cap-like wet moulded products made from the cellulose fibers comprises:
- the male or female shaped forming mould are typically made of a wire mesh that is commonly used today in processed for producing disposable products.
- a bottle cap having an inner thread for use with a bottle having a threaded neck opening into the bottle is provided, where the bottle cap is produced by the above mentioned method steps. Accordingly, a bottle cap is provided that may be used on any type of bottles, preferably any types of recyclable bottles, and that is fully recyclable.
- system for producing bottle caps for use with a bottle having a threaded neck opening into the bottle where the bottle cap is produced from cellulose fibers, the system comprising:
- the means for providing cap-like wet moulded products made from the cellulose fibers comprises a robotic arm and a forming mould mounted to the robotic arm comprising a male or female permeable surface side, where the robotic arm is adapted to:
- the means for placing the cap-like wet moulded products into the heated female die comprises moving the forming mould towards the heated female and releasing the cap-like wet moulded products into the heated female die.
- the means for screwing and un-screwing the elongated structures with the external threads comprises a drill system controlled by a control unit.
- This drill system could as an example comprise plurality of rotatable spouts and where each of the heated elongated structures with the external threads are attached to the spouts, respectively.
- the heating may in one embodiment originate from a heating source that via the drill pressing system.
- Figure 1 shows a flow diagram of method according to the present invention of producing bottle caps for use with a bottle having a threaded neck opening into the bottle, where the bottle cap is produced from cellulose fibers.
- the cellulose fibers may in one embodiment be plant based cellulose, where the plant based cellulose is bagasse produced from sugarcane.
- step S1 101 cap-like wet moulded products are provided made from the cellulose fibers.
- the step of providing the cap-like wet moulded products made from the cellulose fibers comprises in one embodiment moving a male or female shaped forming mould defining the shape of the wet moulded products into pulp containing the cellulose fibers, and supplying vacuum to the forming mould so as to draw pulp through the permeable surface side leaving outwardly facing the cap-like wet moulded products at the permeable surface side.
- step S2 102 the cap-like wet moulded products are placed into a heated female die comprising plurality of cavities defining the shape of the bottle caps to be produced.
- the temperature of the heated die may in one embodiment be in the range of 160°C to 220°C.
- step S3 103 heated elongated structures with external threads are provided having an outer diameter being less than the inner diameter of the cavities of the female mould.
- the temperature of the elongated structure may in one embodiment be in the range 160°C to 220°C.
- step S4 104 the elongated structures with the external threads are screwed into the moulded products while the moulded products are in a wet state towards bottom sections of the plurality of cavities up to a pre-defined position.
- the pre-defined position is preferably a position adjacent to the bottom of the heated die.
- step S5 105 the elongated structures with the external threads are un-screwed out from the moulded products, the screwing and the unscrewing of the elongated structure being adapted to produce the thread on inner surface sides of the bottle caps.
- Figure 2 shows a where the cap-like wet moulded products 203 have been placed into heated female die comprising plurality of cavities 202 defining the shape of the bottle caps to be produced.
