• the invention relates to a push-through packaging with the features of the preamble of claim 1 or the features of the preamble of claim 9 and a packaging unit with the features of the preamble of claim 20.
• Blister packs of the type in question which are often also referred to as blister packs, serve in the pharmaceutical, ecotrophological and cosmetic fields as containers for accommodating corresponding products such as capsules, dragees, tablets, active ingredient balls, etc.
• the lumpy product is located in such a blister pack within the Cup-like upper part, the opening of which is sealed by the sealing film, such as sealing film.
• the product is thus protected against environmental influences such as moisture and dirt and gives the consumer the guarantee of the durability and original condition of the packaged product.
• the side wall of the cup-shaped upper part which is formed from plastic film, is preferably conical in shape and, if necessary, adapted to the geometry of the lumpy product which is in the push-through pack.
• this adaptation relates to the shape of the side wall in the plane parallel to the floor area. In the plane perpendicular to it, that is to say, in a vertical section through the push-through packaging, there is no particularly preferred shape, rather the shape is rather production-related or mechanical-dependent, depending on the design of the molding device.
• the sealing film is occasionally pressed through, but the lumpy product nevertheless does not leave the receiving space in the upper part, but remains there. This may be due to the fact that the upper part, which is formed from plastic film, deforms in such a way that the opening which serves to discharge the product is reduced.
• the teaching is based on the problem of avoiding inadvertent remaining of the lumpy product in a push-through packaging of the type in question by designing the push-through packaging and at the same time to achieve that pressure-sensitive lumpy products can also be handled easily.

This makes the activation process reproducible and safe for the user. Contact of the user with the second product component can be avoided in any case.
• the second partial packaging at least partially covers the opening of the first partial packaging when ready for use. This means that further product components in the ready-to-use state cannot be passed through the opening of the first partial packaging as long as the second partial packaging is fixed to the first partial packaging. In order to be able to add further product components, the second partial packaging must first be detached from the first partial packaging.
