Description

Disposable tray for blister packaging

  pharmaceutical products to be filled under vacuum.

  The invention relates to a disposable tray for packaging pharmaceutical ampoules to be filled under vacuum.

  Currently, pharmaceutical ampoules des-

  designed to be filled under vacuum are sealed on one side,

  and are standing side by side in crystallizers

  covered with lids. These closed crystallizers are grouped in metal overpacks, or more generally in cardboard, and then delivered to the laboratories. The crystallizers and even the overpacks are reusable, and are returned to the manufacturer

  after filling the ampoules and placing them on trestles.

  Before reuse, the crystallizers must be

  washed and washed, and the overpacks must be cleaned and

  dusted. The problem posed by dust is particularly

  particularly acute in the case of cardboard overpacks.

  One of the aims of the invention is to overcome the problems related to the dust of the overpacks, and the cleaning of the crystallizers. Another object of the invention is to provide crystallizers at low cost and put

  easy to use, suitable for empty stacking.

  The subject of the invention is a disposable tray for packaging pharmaceutical ampoules to be filled under vacuum, of the type in which the bulbs are arranged.

  vertically side by side, characterized in that it is con-

  with a flat square bottom, a belt slightly wider than the bottom and oblique amounts to connect the bottom

on the belt.

  According to other characteristics of the invention: the bottom is bordered by a rib to ensure the maintenance of the bulbs;

  in the vicinity of the angles, said rib

  bleeding for the evacuation of a possible liquid; - The amounts comprise a first portion in the vicinity of the bottom, and a second portion in the vicinity of the belt, the first part being more inclined to the vertical -2 than the second;

  - The tray is made of plastic

  only polypropylene type loaded up to 20% talc; two adjacent sides of the tray have one of two regularly distributed uprights, the other a single one in the middle; - for empty stacking, it is shifted by

    compared to the lower tray to prevent distortion

  mation; - when it is full of bulbs to fill, the

  tray is stackable for pallet shipping, the barquet-

  the top of each pile being covered with an empty tray returned, and the set of batteries being sealed under

retractable cover.

  Other features will emerge from the

  following description made with reference to the accompanying drawing on which we can see: Figure 1 - a perspective view of an embodiment of a tray according to the invention;

  Figure 2 - a perspective view of the barquet-

  te of Figure 1 after rotation of 90; Figure 3 - a sectional view along a median plane,

  of the tray of Figure 2, on a larger scale.

  Referring to the drawing, we see that the barquet-

  te according to the invention is made of plastic material resistant to autoclave temperatures, ie 120 C. In a particular embodiment, polypropylene can be used,

  possibly loaded up to 20% talc.

  This tray has a bottom 1 flat and square,

  a belt 2 constituting the edge of the tray and

  3, 4, 5 side and 6 corner, to connect the bottom 1 to the

  2. The edges of the bottom 1 have a rib 7 des-

  designed to maintain the tip of the ampoules to be filled, which are arranged vertically against each other in the tray. This rib 7 has, in the vicinity of the angles,

  small slits 8 to allow the flow of a liquid

  any such, such as a bulb filling liquid or a wash water. To take into account the shape of the cylindrical bulbs with axial points, the belt 2 is slightly wider than the bottom 1. The length of the uprights is such that

  that the belt is generally in the vicinity of

place of the bulbs.

  Apart from the fact that they are arranged obliquely

  The amounts have two peculiarities.

  The first is that they are not straight but angular: they include a first part 9 at

  near the bottom, more inclined to the vertical than the se-

  part 10 in the vicinity of the belt. The line of art

  Figure 11 is visible in Figure 3. This provision of

  uprights facilitates the stacking of trays without deformation.

  The second is that two adjacent sides of the tray do not have the same number of amounts. Thus, in Figure 1, the bottom side carries two uprights 4 and 5 while the right side only carries one, 3, which is clearly visible

  in Figure 2. This arrangement allows stacking after rotation.

  a quarter of a turn of the upper tray without deformation.

  the tray. Indeed, we avoid to stack

amount on amount.

  With the container according to the invention, all the

  bulbs are at the same height because the bottom is very flat. We-

  can therefore stack several full trays without difficulty on a support plate placed on a pallet. The trays

  at the top of the piles can be advantageously

  green of an inverted tray to protect openings

  bulbs external shocks. The whole is then enveloped

  with a retractable cover, thus protecting the whole

any outside dust.

  On arrival at the filling laboratory, the

  trays are handled with their bulbs and they accom-

  These ampoules are used during vacuum filling, autoclaving, washing, welding, etc. After conditioning the ampoules on an easel, the trays are stacked after a relative rotation of 90. They

  can be destroyed, or reused in other applications.

  tions. It should be noted that all operations performed in the laboratory can be fully automatic,

  including the destruction of trays, which avoids any risk

  than pollution related to reuse.

  According to an alternative embodiment, instead of a single amount 3 on one of two adjacent sides of the trays, two amounts are provided, but the arrangement is not identical to that of the two amounts 4 and 5 of the 'other side

  adjacent, so as not to stack up on

  As. In addition, it can be provided at the corners of the tray, an abutment such as 12, so as to ensure the stacking of

  empty trays without deformation.

  It remains well understood that the invention is not

  limited to the embodiment described above.
