Definitions

  • the present invention relates to a drawer case, preferably for breath strips, according to the opening portion of claim 1.
  • a breath strip case is well known since the nineties.
  • US patent 5,016,659 shows a container comprising a plurality of breath sticks
  • US patent application 2004/0079665 shows a breath strip case which consists of a base, a cover and a lid.
  • This case is intended to be air-tight, in order to prevent moisture from entering the case.
  • Breath strips are widely promoted for on-hand-use on demand.
  • pocket-safe boxes which are intended to keep the breath strip ready to use.
  • Such boxes or cases must sufficiently protect the breath strip even if handling is rough.
  • a drawer which is received in the case body and consists of or at least comprises desiccant.
  • the side walls, the rear wall and the bottom wall of the drawer have desiccant such that the closure plate may be made from or contain a different material such as rubber.
  • the closure plate may contain a different material such as rubber.
  • the closure plate may be made from desiccant such that the drawer may be formed integrally in one piece.
  • the desiccant keeps the goods or article contained in the inventive case dry over a long time. Even if the case is opened and re-closed the desiccant continues to keep the goods dry as it is selected to work on a long-term basis. Any desiccant, in particular any desiccant containing polymer composition may be used. Advantageously, the desiccant may not get lost and changed with the good as it is part of the container or case.
  • an air-tight seal may be provided, and the sealing line is - with usual dimensions of drawers - about a third of the sealing line of the above-mentioned prior art document.
  • the sealing may be improved by using a rubber closure plate or a sealing ring due to the elasticity exerting a slight pressure outwardly towards the inner edge of the case opening and thus sealing between the closure plate and the case opening.
  • the drawer has a frictional or a snap lock in the container in the closed state.
  • the drawer does not open unintentionally. Frictional engagement may be ensured by the above-mentioned sealing line between the closure plate and the inner edge of the case opening, using the resilient characteristic of the closure plate.
  • a snap lock is provided, the same shoulder or recess or protrusion may be used both for closure snap lock and for separation snap lock, i.e. an additional snap lock which prevents the drawer from getting fully separated from the case body.
  • any shoulders provided for the snap lock may be made in a rounded or convex arrangement, and also the case body may be produced in one piece and may be made from any suitable plastic, like polypropylene.
  • Figure 1 shows an embodiment of the case 10 according to the invention which basically consists of a case body 12 and a drawer 14.
  • the case body 12 has a longish form as it is usual for cases which are intended to receive drawers. It is made from PP while any other suitable materials might be used as well as long as it is are sufficiently moisture tight and not too expensive. Other examples are PE, PA or PU. It is also possible to provide an thin layer e.g. from aluminium or any other suitable substance on the inner side of the body in order to ensure the moisture tightness.
  • the drawer 14 generally has the usual rectangular shape of a drawer. Thus, it has side walls 16, a rear wall and a bottom wall 20. In this example however, the bottom wall 20 is sloped from the front end 22 towards the rear end 24 of the drawer 14. By this, a breath strip 26 may easily be taken out even if it fully covers the bottom wall 20, just by drawing it towards front end, with a finger pressed on its upper surface.
  • the drawer 14 consists of a desiccant-entrained composition such as those disclosed in US Patent Application Serial No. 10/328,579 or US 5,432,214 A1 in this embodiment.
  • a desiccant-entrained composition such as those disclosed in US Patent Application Serial No. 10/328,579 or US 5,432,214 A1 in this embodiment.
  • Any desiccant material e.g. one made from a polymer plastic material with desiccant particles being contained or entrained therein may be used.
  • Other suitable desiccants may be used, and it is also possible to have a desiccant layer arranged on the inner side of the drawer 14.
  • the drawer 14 is equipped with a special closure plate 30.
  • the closure plate 30 is made from or contain rubber and is firmly attached to the remainder of the drawer 14. Its outer dimensions are such that they form a grip projection 32 at its top and bottom ends which overtop the respective parts of the case body 12 in the closed state of the drawer.
  • the bottom wall is slanted, and, close to the front end 22, upwardly bend.
  • the first lock consists of projections or shoulders 34 and 36 arrange facing upwardly and downwardly on the drawer, close to the front end 22, and corresponding projections or shoulders 38 and 40 arranged near an opening 42 of the case body 12 and facing towards the drawer 14.
  • the shoulders 34 to 40 keep the drawer 14 sately in the closed state while it may be opened when manually drawing at grip projections 32.
  • a further locking shoulder arrangement forming the second snap lock with locking shoulders 44 and 46 is arranged at the rear end 24 of the drawer 14, extending from rear wall 18. Contrary to the rounded protrusions 34 and 36, these shoulders 44 and 46 have sharp edges facing toward the front end 22 of the drawer 14 such that the force required to fully separate the drawer 14 from the case body 12 is considerably higher, e.g. three times higher than the force required to open the drawer.
  • the stiffness of the case body 12 may be selected in a suitable manner.
  • Figure 2 shows the embodiment according to figure 1 in the closed state. Same reference numerals correspond to same parts.
  • the closure plate 30 is inserted into the opening 42 of the case body 12. It has a press-fit there allowing a sealing around a sealing line 50.
  • this sealing line may also be provided with a very small ridge which is not shown in the figures 1 and 2.
  • the sealing line 50 is also protected as it is arranged internally.
  • Figure 3 shows that ribs 60 and 62 are provided extending in the moving direction of the drawer 14 near the lateral ends of the case body 12. These ribs are both for stiffening the case body and for design purposes.
  • the grip projections 32 are provided in a central area of closure plate 30. It will be understood that it is possible to have them arranged in any other suitable manner.
  • Figure 4 shows how the protrusion 40 extends nearly over the full width of case body 12.
  • the protrusions 34 and 36 arranged on the drawer 14, on the other hand, may be provided only at the corresponding side wall 16.
  • Figure 5 shows an alternative embodiment of the closure plate 30 for the drawer 14.
  • a sealing ring 70 is provided on a horizontal portion 72 of the closure plate which is intended to be pressed agains the opening 42 of the case body 12.
  • Figure 6 shows a different embodiment of the sealing means.
  • a sealing layer 74 is provided both on the horizontal portion 72 and the oblique portion 76 of the closure plate.
  • Both, the sealing 70 and the sealing layer 74 may be made from or contain rubber or similar elastic materials with sealing properties.
