Definitions

  • the present invention relates to a blister pack for pharmaceuticals from a bottom part with a plurality of wells arranged in rows or in concentric circles and are surrounded by a shoulder and one attached to the shoulder Cover film, with a removable content is in the wells and through Press in the respective recess and puncture the lid film through the contents or by removing the cover film over the recess, the content is removed, the blister pack having a movable lid which covers the depressions and the lid is slidably disposed over the lid sheet and a lid Clamping element is arranged movably over the cover film surface and that the Clamp element contains at least one cover element, which has at least one open Recess covers and that the clip element slides along the blister pack is displaceable and that the clamp element has at least one recess with pierced or the removed cover film or at least one recess, which remains unfilled and uncovered when initially filled.
  • From DE-A-29 19 713 is a child-resistant pharmaceutical packaging from one Base film, a push-through film and a security film known.
  • the security film can be a longitudinally movable slide with terminal strips. To the effect of To ensure child safety, the security film must definitely the whole Cover the surface of the push-through foil. This represents - will not be a child lock required - represents a high expenditure of packaging material.
  • the blister pack is characterized by a single or in particular a plurality of individual subjects, in which, for example, solid moldings or shaped solid preparations or pharmaceutical products such as tablets or dragées are stored. If a single item, e.g. a Tablet, are removed, a depression is pressed into the bottom part and the tablet in turn pierces the lid material.
  • blister packs for example, the cover material made of an aluminum foil or an aluminum foil composite manufactured.
  • the aluminum foil is a preferred material for blister lids because relatively low breaking forces are required for the selected thickness of the cover materials, and thus the puncture energy required is low and the aluminum essentially shows no elasticity.
  • the bottom of the blister pack is made of plastic, like from Plastics, for example, the series of PVC, polyamides, polyolefins, polyesters and Compound or multilayer materials containing at least one of these materials, and optionally also containing an aluminum foil.
  • Other blister packs have a bottom part which is covered with a cover film.
  • the lidding film can completely cover the bottom part and is advantageous in the area of each recess Cover material with a line of weakness or each recess can with a individual cover segment. Within the line of weakness or on everyone A tab can be attached to the cover segment, which enables a single depression to expose by peeling (peeling) the lid segment.
  • the floor parts and the Lid materials are usually made of the materials mentioned, being for the lid materials plastic composites can also be used.
  • blister packs In the field of healthcare, but also for the distribution of confectionery such as pastilles and sweets, such blister packs have found wide acceptance and are popular because of the Possibility of gentle storage of sensitive contents and because of the light Manageable removal of content from everyday life is indispensable. in the Signs of increased health care efforts are aimed at blister packs to keep it as small as possible and also to limit the number of different formulations. This can mean that a pharmaceutical formulation only has one Concentration level is fabricated and it can happen that not a whole Tablet or a whole tablet must be taken, but e.g. according to the Body weight or the course of the disease in a patient only a subset, e.g. the Half of a tablet or tablet must be administered.
  • the object of the present invention is to propose blister packs which make it possible unused remaining quantities, e.g. Parts of a tablet or a dragee or one of several dragées, capsules or ampoules, still safe, i.e. captive and before Protect against external influences such as moisture and dirt until use.
  • the bottom parts of existing blister packs can be embossed, cast, deep-drawn or vacuum-formed base parts made of plastic, plastic composite, plastic / paper composite or plastic / metal foils.
  • Suitable plastics for Floor materials are, for example, films and film composites containing PVC, polyamides, Polyolefins, polyesters, polycarbonates etc.
  • the bottom parts can also have a barrier layer against gases and vapors.
  • barrier layers can, for example, be one in one Plastic composite embedded metal foil, such as an aluminum foil, or be, expedient arranged between two plastic layers, ceramic layers or metallic layers.
  • Ceramic layers can be evaporated, for example of metals, oxides or nitrides of aluminum, silicon and other metals and Semi-metals are created in a vacuum and the substances are deposited on a plastic carrier become. These processes are known, for example, under chemical vapor deposition and Physical vapor deposition or sputtering.
  • the ceramic layers can be preferred Aluminum oxides or silicon oxides contain or can be mixtures of different oxides optionally also in a mixture with metals, such as silicon or aluminum or be another.
  • Metallic layers can be created by evaporating Metals in vacuum and depositing the metals on a plastic support, whereby Aluminum layers can be mentioned as examples.
  • the plastic carrier can Plastic film or a plastic base part made of the plastics mentioned.
  • the Lid material for blister packs is usually an aluminum foil or one containing aluminum foil Composite.
  • the aluminum foil has also been proposed to be replaced by a plastic that has low elasticity and poor stretch properties having. Such plastics are e.g. get when larger amounts of fillers be mixed into the plastic. This latter variant would allow single varieties Obtaining waste does not mean a mixture of metal and plastics.
  • plastic films and Plastic film composites are used for blister packs With peelable (peelable) lid material.
  • the bottom parts usually have between 6 and 30 wells, such as cells or bowls. The depressions are all around one Shoulder surrounded, the shoulders overall a coherent, flat surface form.
  • the bottom parts are provided, for example, as continuous material with the content filled and the cover material, in particular as a cover film, also as an endless material run up.
  • the cover film covers the bottom parts over the entire surface and, for example sealing or gluing connects the lid film to the base part at the shoulders.
  • the cover film can be sealed or glued over the entire surface of the shoulders or by choosing a sealing tool or an adhesive pattern, this sealing can or gluing only partially.
  • the endless band of covered Bottom parts to be cut to the clothing sizes. For example done by a punch.
  • the blister packs external contours are also given or it is possible to weaken the lid material or in the bottom part to fold a blister pack, for example or to create lid segments which are easy removal of the lid segment and allow removal of the content.
  • a clamp element covers at least one depression.
  • a bracket element can also Cover two, three or four wells at the same time.
  • tongues can be a whole row or part of a row of depressions, i.e. for example, cover two, three, four, etc. depressions.
  • Deck elements can a whole series of depressions, each with, for example, one, two, three, cover four etc. wells. Appropriately, the maximum number corresponds to the by Clamp element covered depressions of the number of depressions in a blister pack less one.
