Claims (4)

1 . A method for a production of a hygiene product with at least one application unit, with at least one handle unit that is connected to the application unit, and with at least one volume body, which at least partially forms the application unit and/or the handle unit and which is made at least partially of a foamed material, comprising at least one base body, which is connected to the volume body and which at least partially forms the application unit and/or the handle unit, wherein the at least one volume body is molded to the at least one base body, wherein the at least one base body comprises at least one form-fit element, which forms a form-fit connection with the at least one volume body, the method comprising: forming the hygiene product, wherein the volume body is at least section-wise densified after a shaping process.
2 . The method according to claim 1 , wherein in at least one method step the volume body is molded to the base body directly by means of a foaming method.
3 . The method according to claim 1 , wherein in at least one method step the at least one enveloping body and/or the at least one base body are/is molded to the volume body by means of an injection-molding process.
4 . The method according to claim 1 , wherein in a region of the application unit, the volume body is at least section-wise densified after a shaping process.

Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is based on and incorporates herein by reference the European patent application EP 20175812.5, filed on May 20, 2020, as well as the PCT application PCT/EP2021/063487, filed on May 20, 2021. PRIOR ART The invention concerns a hygiene product, in particular an oral hygiene product. From EP 0 758 534 B1 and U.S. Pat. No. 4,283,808 hygiene products, in particular oral hygiene products, are already known, with at least one application unit, with at least one handle unit that is connected to the application unit, and with at least one volume body which at least partially forms the application unit and/or the handle unit and which is made at least partially of a foamed material. Furthermore, from DE 20 2004 015 133 U1, from WO 2020/193760 A1 and from U.S. Pat. No. 9,138,048 B2 hygiene products are already known, too. The objective of the invention is in particular to provide a generic device having improved characteristics with regard to material efficiency, weight and/or ergonomics. The objective is achieved according to the invention while advantageous implementations and further developments of the invention may be gathered from the subclaims. Advantages of the Invention The invention is based on a hygiene product, in particular an oral hygiene product, with at least one application unit, with at least one handle unit that is connected to the application unit, and with at least one volume body which at least partially forms the application unit and/or the handle unit and which is made at least partially of a foamed material. It is proposed that the hygiene product comprises at least one base body which is connected to the volume body and which at least partially forms the application unit and/or the handle unit, wherein the at least one volume body is molded to the at least one base body. The volume body is preferably produced in a foaming process and in particular forms at least a portion of the handle unit and/or of the application unit. Preferably the hygiene product is implemented of an application unit with bristles and of the handle unit, the application unit in particular having a neck region that connects the application unit to the handle unit. All the sub-elements may be implemented of at least one hard component and/or one or several soft component/s and/or of a foamed material. Both customary hard and/or soft components or sustainable hard and/or soft components are applicable. The implementation of the hygiene product according to the invention allows providing advantageous characteristics with regard to ergonomics of the hygiene product. In particular, advantageous grippability of the handle unit is achievable. Furthermore, this in particular allows keeping a weight of the hygiene product at a low level, in particular without affecting ergonomics, in particular a grippability, of the hygiene product. It is in particular possible to provide a body that is lightweight but voluminous. For example, it is possible to produce a lightweight toothbrush that is still voluminous. As a result, the hygiene product is light as a feather and its surface is rather soft and feels warm. In particular, material input for the hygiene product can be kept at a low level. This allows providing an advantageously ecological and/or sustainable hygiene product. By a “hygiene product” is in particular an oral hygiene product to be understood, preferably a toothbrush. Alternatively the hygiene product may be implemented by a body care product, for example for hair removal, like in particular a shaving-brush handle or a safety razor, and/or by a hairbrush, in particular an elongate hairbrush handle or a hairbrush handle having, for example, the shape of a shell (which the bristle field is inserted in). It would also be conceivable that the hygiene product is implemented by a cosmetics applicator, like in particular a handle for a mascara brush or a mascara applicator, a mascara container, a nail polish brush handle, a nail polish brush container, a face brush, a handle for a make-up applicator and/or a make-up container. Alternatively the hygiene product may be implemented by a household utensil, like in particular a handle element on a grip of a washing-up brush, a handle element on a grip of a toilet brush handle, a handle element on a grip of a floor wiper, on the handle of a dustpan and/or a handle element on a broomstick of a broom. The hygiene product may moreover be implemented by a packaging and/or by an auxiliary means, like in particular a dental-floss box, a cream jar and/or a face brush socket. An “oral hygiene product” is in particular to mean a toothbrush and/or an interdental cleaner and/or an interdental brush and/or a flosser and/or a tongue cleaner and/or a toothpick. Advantageously the oral hygiene product is realized as a toothbrush, in particular a manual toothbrush, preferably a children's toothbrush or a toothbrush for adults, advantageously a p
