Problems solved by technology

[0006] Such configurations of pumps and their diaphragms are often problematic for drying out of the contents of the pump, so that liquid can seep out of the diaphragm over time via diffusion
On the other hand, cost pressures on such disposable bags are difficult to address

Embodiment Construction

[0046] Figure 1 to Figure 4 The shown refill pack 1 contains toothpaste and can be placed in an electric toothbrush which transfers the toothpaste contained therein out of said refill pack 1 . The refill pack 1 has a generally rectangular profile and may be roughly referred to as being "sausage-shaped", wherein the cross-section of the refill pack tapers towards one of its ends; see the right end of FIG. 1 . The refill pack 1 comprises a rectangular supply container 2 having a sausage-shaped profile with a flattened end. In the described embodiment, the refill pack is designed as a foil pouch welded together from flat foils or flat foil pieces. In this context, the supply container 2 can in particular be made of a permanently airtight and diffusion-resistant barrier foil, which can have a multilayer construction, and in particular can have a barrier layer made of aluminum and at least one Carrier layer made of vinyl.

[0047] On the front side of the supply container 2 arr...

Abstract

The present invention relates to a personal use device, preferably a toothbrush, a shaving device, or a hair removal device. The invention relates to a refill pack for such a personal use device, having a supply container (2), particularly a supply bag, containing at least one hygiene or care substance such as toothpaste or the like, and a pump (3) tightly connected to the supply container, the pump chamber of which is connected to the interior (6) of the supply container via an input valve (5). By deformation of a membrane which bounds the pump chamber (7), the pump chamber volume can be changed. The invention also relates to a method for filling such a refill pack.

Description

technical field [0001] The invention relates to a device for personal use, preferably a toothbrush, a shaving device or a hair removal device. In one aspect, the invention relates to a refill pack for such a device for personal use, said refill pack having a supply container, in particular a supply pouch. The supply container contains at least one care and / or therapeutic substance to be dispensed, such as toothpaste or the like, and has a pump firmly connected to the supply container, the pump chamber of which is connected to the interior cavity of the supply container via an inlet valve, And the volume of the pump chamber can be changed by deformation of the membrane for confining the pump chamber. The invention also relates to a method for filling such refill packs. Background technique [0002] In electronic devices intended for personal use, it is known to deliver substances that aid care or cleaning, in addition to mechanical processing effects. For example, an elect...
