Definitions
- the present invention relates to a closure cap for a container for holding cosmetic creams, liquids or pasty substances, such as mascara in particular, wherein the closure cap is designed as a material hybrid with a connection area formed on the inside of a base body of the closure cap made of metal, plastic or ceramic Establishing a connection between the closure cap and the vessel in the form of a screw connection, a bayonet connection or the like.
- the invention relates to a vessel provided with such a closure cap and to a method for producing a closure cap.
- Closure caps of the type mentioned at the outset, which are designed as material hybrids, are known in different designs, with one approach to enabling the recycling of such closure caps is to design the closure caps in such a way that components of the closure cap made of different materials are used in the production of the Cap can be separably connected to each other, for example, a made of plastic Being able to separate the inner cap, which simultaneously forms a cap thread of the closure cap, as a prerequisite for recycling the different materials from an outer cap of the closure cap made of aluminum.
- Such a construction of a closure cap designed as a material hybrid requires the individual components to be manufactured independently of one another, which must subsequently be assembled in a further separate assembly step. For recycling such a closure cap, this means that the closure cap must be handled again in order to separate the components from one another.
- Another possible approach is to dispense with the formation of mechanical interfaces between the components that allow the components to be separated for recycling, and instead to eliminate one or more of the combined materials, so that, for example, plastic parts are dissolved or burned to to recycle metal parts.
- plastic parts are dissolved or burned to to recycle metal parts.
- the present invention is based on the object of proposing a type of closure cap designed as a hybrid material that enables simple recycling with minimal impairment of the ecological balance.
- closure cap according to the invention has the features of claim 1.
- the closure cap has a connection area formed on an inner side of a base body of the closure cap made of metal, plastic or ceramic for producing a screw connection, bayonet connection or the like Connection of the closure cap to the vessel, wherein the connection region has only a portion of a plastic material as a contact material for forming a physical contact between the closure cap and the vessel and is otherwise formed from the material of the base body.
- the plastic material used as the contact material differs in its chemical and/or physical properties from the plastic material of the base body.
- the use of a contact material formed from a plastic material only in a portion of the connection region, which portion is otherwise formed from the material of the body, requires only the elimination of a relatively small proportion by volume or weight in preparation for recycling the material used for the body of the closure cap compared to a closure cap in which approximately the entire connection area consists of a different plastic material from the base body.
- the connecting portion consists of a connecting portion made of a plastic material in its entirety, so that the plastic content to be sacrificed as a prerequisite for recycling the main body material can be significantly reduced.
- the essential function of the plastic material used in the connection area is to form a friction partner when producing the connection between the closure cap and the vessel, which, for example in the case of a screw connection between the closure cap and a metal thread of the vessel, the friction behavior is positively influenced, so that when the container is opened or closed, the result is a correspondingly positive haptic perception by the user.
- the proportion by volume or weight of the contact material is preferably less than or equal to 8%, particularly preferably less than or equal to 5%.
- the contact material consists of a thermoplastic material that is soft compared to the material of the closure cap, such as in particular TPE (thermoplastic elastomers), the advantages described above can be achieved to a particular extent.
- TPE thermoplastic elastomers
- the invention can be implemented particularly easily in the case when the connection region is used to produce a screw connection.
- the contact material also forms a cap seal between the base body and an opening edge of a vessel opening of the vessel, one and the same contact material can advantageously be used both to form a thread and to form a sealing surface.
- sealing surface is designed as an annular or circular surface.
- the thread and the cap seal are formed from a continuous composite contact material, the thread and the cap seal can be produced particularly economically in a joint injection molding process.
- a particularly effective use of the contact material both to achieve the advantageous haptic perception mentioned at the outset and with regard to minimizing the material proportion of the contact material in the total volume or the total weight of the closure cap as far as possible can be achieved if the Thread has a profile with expiring in the transition to the surface of the base profile flanks.
- the thread is composed of thread segments spaced apart from one another in the direction of the thread.
- the thread is designed as a trapezoidal thread.
- the contact material forms contact islands on the inside of the base body between thread segments formed on the inside of the base body, there is the possibility of forming the thread in the connection area of the base body from the material of the base body and using the contact material on the formation of the contact islands formed between the thread segments to restrict.
- a cap seal is preferably formed between the base body and an opening edge of a vessel opening of the vessel made of the contact material.
- the thread segments are formed from the material of the base body, so that the amount of contact material used can be further reduced.
- the contact islands are designed as a plurality of strands of contact material, which extend in the axial direction within the connection area, a uniform circumferential support of the closure cap on the vessel can be achieved with an appropriate circumferential distribution of the strands of contact material during an opening or closing process, which has a correspondingly positive effect on the haptic Affects user perception.
- the strands of contact material can also be produced in a molding process, in particular an injection molding process, with the thread or the contact material strands being connected to the cap seal on the base body can be formed themselves and thus the thread or the strands of contact material can form a contact material composite with the cap seal.
- the strands of contact material it is particularly advantageous if a central part that combines the individual strands of contact is used to form the cap seal.
- the base body of the closure cap forms an inner cap arranged in an outer cap
- complex configurations of a closure cap are also possible on the basis of the base body provided with the contact material, in which further design options for the closure cap are opened up, for example, by an outer cap formed independently of the base body.
- the vessel according to the invention has the features of claim 18.
- the method according to the invention for producing a closure cap provides according to claim 19 that the contact material is applied to the surface of the inside of the base body in a coating process is applied, so that a material bond between the contact material and the material of the base body is produced and the base body forms a carrier substrate when the contact material is formed on the inside of the base body.
- the base forms part of a mold, which is particularly the case when the contact material is applied to the surface of the inside of the base in an injection molding process.
- a closure cap 11 is shown, which is shown in combination with a vessel 10 designed here as a jar.
- the closure cap 11 has a total of four components, with a cap insert 14 embodied here as a cap weight being accommodated between a base body 12 designed as an inner cap and an outer cap 13 this supplements the base body 12 provided on its inside 15 with a cap thread 16 and a cap seal 17 .
- the cap thread 16 extends with a thread 18 over a connecting area formed on the inside 15 of the base body 12 , the thread 18 being in engagement with a vessel thread 20 formed on a vessel neck 19 of the vessel 10 .
- the cap seal 17 arranged on a cap base 21 of the base body 12 designed as an inner cap is in sealing contact with an opening edge 34 of the vessel 10 .
- both the thread 18 of the cap thread 16 and the cap seal 17 are formed from a contact material 22 which is injection molded onto the inside 15 of the base body 12, which in the present case coincides with the outer cap 13 made of aluminum.
- the thread 18 and the cap seal 17 form a contact material composite 23, which is arranged on the inside 15 of the base body 12, wherein if the contact material composite 23 is produced in an injection molding process, the base body 12 can serve as part of a mold , such that the base body 12 together with a mold core 32 inserted into the base body 12, which in 4 is indicated hatched, in the production of the contact material composite 23 forms a mold cavity for the contact material composite 23 .
- the contact material 22 can be fed into the mold cavity through a central bore 33 formed in the cap base 21 of the base body 12, so that, as in 4 shown, after the production of the contact material composite 23 , this has a sprue 26 formed in the central bore 25 .
- the thread 18 designed here as a trapezoidal thread has a profile 27 with profile flanks 29 tapering off in the transition to a surface 28 of the inside 15 of the base body 12, with a valley bottom 30 of a thread valley 31 formed between axially adjacent profile flanks 29 having no contact material, so that here in the present case the surface 28 is formed from the material of the base body 12, ie in the present case the aluminum.
- the haptic perception of the user during an opening or closing process is determined by the contact or frictional behavior of the contact material 22 in relation to the material of the vessel 10, in particular when using TPE as the plastic material, in particular when there is a friction pairing of TPE as the contact material and aluminum or a comparatively hard plastic material for the vessel 10, a snug fit of the closure cap 11 is achieved in connection with a frictional resistance that is perceived as pleasant when screwing on or off.
- the pairing of materials can take place in such a way that, on the one hand, good adhesion of the contact material 22 to, for example, metal, plastic, glass and ceramics and, on the other hand, good friction and sliding properties can be set, in particular to also eliminate noise when the vessel 10 is closed or opened to dampen.
- connection area i.e. the area on the inside 15 of the base body 12 over which the thread 18 extends, can be designed in such a way that the entire forces and torques are carried by the contact material 22, as in the case of FIG 3 illustrated embodiment.
- a prestressed shape of the closure cap can be used, which is based on the shape of the "Reuleaux triangle".
- the flexibility of the base body 12 then serves as a spring and compensates for tolerances in the gaps between the closure cap 11 and the vessel 10, so that a high-quality feel can be achieved, in particular independently of the ambient temperature.
- a closure cap 40 is shown, which in 8 in combination with a vessel 41 is shown. How in particular 9 shows, has the cap 40 a base body 42, which in accordance with the referring to the Figures 1 to 5
- the closure cap 11 shown is designed as an inner cap of the closure cap 40, a cap insert 43 designed as a cap weight being provided between the base body 42 and an outer cap 49, which here also corresponds to the base body 42 and is also made of aluminum.
- the base body 42 is provided on its inner side 44 with a contact material composite 45, which is also preferably applied to the inner side 44 of the base body 42 in an injection molding process and has a plurality of contact material strands 47 extending axially over a connecting region formed on the inner side 44. which are arranged on a cap bottom 48 of the base body 42 central part of the contact material composite 45 which forms a cap seal 48 in connection.
- a contact material composite 45 which is also preferably applied to the inner side 44 of the base body 42 in an injection molding process and has a plurality of contact material strands 47 extending axially over a connecting region formed on the inner side 44. which are arranged on a cap bottom 48 of the base body 42 central part of the contact material composite 45 which forms a cap seal 48 in connection.
- the contact material composite 45 is also applied to the inside 44 of the base body 42 in an injection molding process.
- the contact material strands 47 extend between formed on the inside 44 of the base body 42 thread segments 51, which are formed in the present case from the material of the base body 42, so here aluminum, so that in the case of in the Figures 6 to 10
- the forces in the screw connection are essentially transmitted via the thread segments 51 formed from the material of the base body 42, with the strands of contact material 47 providing radial support and, due to their material properties, an elastically flexible reduction in the forces acting in the screw connection enable and thus contribute to an increase in the haptic quality during the screwing process.
