Abstract

A reaction vessel (1) made of plastic for small amounts of liquid is provided with a lid (2) for closing the opening of the vessel (1). The cover (2) is held in the closed position by a securing device consisting of a bending tab (7) and a securing pin (9). <IMAGE>

Description

  • The invention relates to a reaction vessel made of plastic for small amounts of liquid. Such reaction vessels, which often replace test tubes, are e.g. known from German Ausleschrift 1 275 795 or European patent specification 149 797. In such reaction vessels, a lid is provided, which is usually molded onto the reaction vessel in one piece. As is known from column 3, line 25 of DE-AS 1275 795, for example, a profile, for example an annular groove on the lid projection and a bead-like ring profile on the mouth of the vessel, can be provided for the positive connection of the lid and reaction vessel, so that the lid engages when it is put on . Generally speaking, such a construction is a snap lock. EP-PS 149 797 also relates to a snap lock, but a hook-like attachment provided on the edge of the lid, which snaps over a locking edge, serves as the snap member.
  • Such snap locks are dependent in their function on the elasticity of the plastic used and thus last but not least on the effects of temperature or signs of aging. In practice it has been shown that such snap closures are used when the pressure in the reaction vessel increases significantly, e.g. do not remain reliably closed when heating, shaking or falling.
  • Particular problems would still arise with snap locks if elastic sealing elements were provided which are tensioned against the closing pressure of the snap lock. Reaction vessels with sealing elements are therefore in usually closed with complex screw connections or additional locking clips.
  • In practice, it has also been shown that ease of use is impaired, particularly with hook-type snap locks. The strong pre-tension required by the hook fastener makes opening difficult, especially the one-handed opening by an operator.
  • The object of the invention is to avoid the disadvantages of the known, in particular to create a reaction vessel made of plastic which can be reliably secured in the closed state, which is nevertheless easy to open and which can be manufactured simply and economically.
  • According to the invention, this is achieved primarily by a reaction vessel according to the characterizing part of claim 1. Instead of the known snap closures on reaction vessels, a securing device is provided according to the invention, with which the lid and vessel are connected in a form-fitting manner. Obviously, the positive connection by means of the securing device ensures a firm connection between the lid and the vessel. If the security device e.g. has a bending tab with at least one opening, this can easily be made in one piece from the plastic of the lid and / or the vessel, in particular it can be injection molded. The same applies to the locking pin, over which the bending tab with its opening can be inserted and thus secured. Overall, the reaction vessel, lid and securing device can be arranged in such a way that they can be produced in one piece and in one operation using the injection molding process, which ensures economical production.
  • The invention can be implemented and handled particularly easily if the bending tab is attached to the lid and the securing pin is attached to the vessel. Especially in terms of injection molding simple solutions can be found with fast injection molding cycles. If the lid is connected on one side to the edge of the vessel by a bending web, it may be sufficient if, for example, a bending tab is provided in the region radially opposite the connecting web for securing the lid. As can be seen, the lid is held firmly on the opening of the reaction vessel on the one hand by the bending tab of the securing device and on the other hand by the bending or connecting web. In order to reliably prevent the bending tab from jumping off the securing pin, it is advantageous if the securing pin has at least one latching edge on its side opposite the opening of the cover. In this way, the bending tab can be positively jammed behind the locking edge, which prevents the bending tab from accidentally opening. In order to optimize the engagement of the bending tab on the securing pin, it can be advantageous to provide a spring element that is prestressed in the opening direction between the lid and the vessel. The spring element can be provided on the cover or on the vessel or can be designed as a separate component.
  • It is also advantageous if a projection adjacent to the bending tab is provided. The projection can serve on the one hand to cover the bending tab so that it is not opened accidentally. On the other hand, the projection can also be designed as a rigid push-off lug provided on the cover, in order to facilitate the opening of the cover and, above all, to enable it with one hand.
  • Of course, the securing device provided according to the invention can be provided in addition to the known snap-lock devices, for example according to DE-PS 1275 795. This makes it possible to close the safety device only when necessary, for example before centrifuging or before heat treatment of a reaction vessel, when temporary opening and closing, however, to leave the safety device inoperative.
  • The invention can be implemented in a particularly user-friendly manner if two push-off lugs are provided on the lid at a distance from one another, which run approximately in the plane of the lid and if the bending tab is arranged between the push-off lugs.
  • Particularly reliable sealing of the reaction vessel can be achieved if an elastic seal is provided between the lid and the vessel, which is held under tension by the securing device. The preload caused by the securing device leads to compression of the elastic seal, which means e.g. the escape of gases with considerable internal pressure in the reaction vessel can also be prevented.
  • In terms of construction, such an inner seal can be easily realized if an annular seal is provided. The seal can be used as a separate sealing element or as an elastic sealing part molded onto the lid and / or the vessel, e.g. be designed as a sealing lip.
  • Particularly good protection of the opening of the reaction vessel and against accidental contact with contaminated parts of the lid area can be achieved according to the invention if a lid is provided which surrounds the rim of the vessel in a cap-like manner and if the seal is arranged between the cap bottom and the rim of the vessel.
  • The invention is explained in more detail below in exemplary embodiments. Show it:
    • FIG. 1 shows the schematic representation of a reaction vessel in section,
    • FIG. 2 shows the top view of the lid of the reaction vessel according to FIG. 1,
    • FIG. 3 shows the view of the reaction vessel according to FIG. 1 from below,
    • FIG. 4 shows the reaction vessel according to FIGS. 1 to 3 in the closed state,
    • FIG. 5 shows the schematic sectional illustration of a reaction vessel with an elastic sealing element,
    • Figure 6 shows the partial section through a modified reaction vessel with a lid, on section along line A in Figure 7 and
    • FIG. 7 shows a top view of the cover according to FIG. 6.
  • According to FIGS. 1 to 4, a reaction vessel 1 produced in the injection molding process is formed in one piece with a lid 2. Reaction vessel 1 and lid 2 are connected by a web 3 such that web 3 on the one hand holds lid 2 captively on reaction vessel 1 and, on the other hand, according to FIG. 4, lid 2 is held in its hinge-like position by web 3 in the closed state. The cover 2 has a cylindrical sealing part 4, which is provided at the end with a bead-like sealing element 4a. When the lid is closed, the sealing element 4a snaps into a corresponding annular recess 1a in the inner wall of the reaction vessel 1. In this respect, it is a snap closure, the sealing element 4a taking on the double function of sealing and snapping.
  • On the cover 2, two projections 5, 6 are provided, which take over the function of push-off lugs. To open the closed reaction vessel 1, the user can simply use press your thumb against the projection 5 or 6 and push the sealing part 4 upwards out of the vessel 1. A bending tab 7 with an opening 8 is arranged between the two projections 5, 6. In the unbent state, the bending tab 7 is aligned with the projections 5 and 6.
  • After the reaction vessel 1 has been closed by the lid 2, the bending tab 7 according to FIG. 4 can be bent downwards in such a way that the opening 5 snaps over a securing pin 9 provided on the vessel 1. The locking pin 9 has a locking edge 10 on its underside, which prevents the bending tab 7 from detaching itself from the locking pin 9. A lip-like spring element 6a is provided on the cover 2 and is pressed together when the cover 2 is closed. This creates a force acting in the direction of arrow A (FIG. 4), which pulls the bending tab 7 behind the locking edge 10.
  • For opening, on the other hand, the bending tab 7 can simply be slipped over the locking pin 9 and the cover 2 then raised on the projections 5 and 6. This can also be done with one hand.
  • In the exemplary embodiments according to FIGS. 1 to 4, the cover 2 is secured in the closed state by the web 3 with its hinge function and the bending tab 7. Of course, it is also conceivable to provide not just one but several bending tabs if a container has to be secured several times. It is also conceivable to also provide a bending tab 7 instead of the web 3.
  • The projections 5 and 6 protect the bending tab 7 particularly advantageously against unintentional opening. Alternatively, it would of course also be conceivable to provide only one projection or to provide a plate-shaped, protruding edge, by means of which the cover 2 is raised and opened can be. Although the arrangement of the bending tab 7 on the lid 2 enables particularly simple manufacture and manipulation, embodiments are also conceivable in which the bending tab 7 is attached to the vessel 1 and the securing pin 9 to the lid 2.
  • FIG. 5 shows an exemplary embodiment of the invention, in which an elastic sealing ring 11 is arranged between the cover 2 and the rim 12 of the vessel 1. Particularly good sealing of the vessel 1 is brought about by the elastic sealing ring 11. When closing, the lid 2 is first pressed so firmly into the vessel 1 that the bending tab 7 can be pushed over the locking edge 10 of the locking pin 9. Thereafter, the sealing ring 11 can relax again somewhat, the bending tab 7 being pulled firmly under the locking edge 10.
  • In the exemplary embodiment according to FIGS. 6 and 7, a lid 14 is shown which surrounds the mouth of a reaction vessel 1 from the outside. Analogous to the exemplary embodiment according to FIGS. 1 to 4, a bead-like sealing element 14a is provided on the cover 14, which surrounds the vessel mouth 15 in a sealing manner and snaps into a complementary groove 1a. In addition, an annular elastic seal 16 is provided on the bottom of the cover 14, which seals the end face of the vessel mouth 15. On the vessel 1, two bending tabs 7 are provided, which can be bent upwards in such a way that, analogously to the exemplary embodiments according to FIGS. 1 to 5, they can be pushed with openings 8 over locking pins 9 which are fastened to the lid 14. The locking pins 9 are bordered on both sides by projections 5, 6, whereby the bending tabs 7 are also protected.
