Description

The invention relates to a lidded plastic container for laboratory use.

Lidded vessels of the type mentioned typically have a capacity of a few tens of milliliters or a few milliliters or a milliliter or less.

Known plastic lidded containers for laboratory use have a tubular vessel having at the bottom a vessel bottom, at the top a vessel opening and below the vessel opening at the inside wall a sealing area. A lid having a lid bottom and a stopper protruding from the inside of the lid bottom is insertable through the vessel opening into a sealing position in the sealing area. The lid is sealed and held by the clamping force of the plug in the vessel. There are applications in which a sample liquid filled in the vessel is heated and has an increased vapor pressure. For example, in the Polymerase Chain Reaction (PCR) technology, for example, samples in lidded vessels are repeatedly heated to temperatures above 90 ° C. The clamping force of the plug shall be such that adequate vapor-tightness is ensured and the lid does not release under the increased vapor pressure. As a result, a high force is required to press the lid with the stopper into the vessel. To open the lid, the user must press firmly against the lower edge of a protruding edge of the lid bottom.

From the EP 0 841 093 A2 and US 5,863,791 a lidded vessel of the type described above is known, are connected to the vessel and lid via a hinge hinge integrally pivotable with each other. The lid has a locking hook projecting downwardly from a laterally projecting lid flange and the vessel next to the vessel opening in the closed position of the locking hook behind engaged locking cam on. When closing the lid of the rigid locking hook snaps under elastic deformation of the cover flange behind the locking cam, whereby the lid is secured in the closed position. To open the lid, the user must push up the lid flange so that it is bent upwards and the locking hook is released from the locking cam. For this purpose, locking hook and locking cam only a small overlap. Due to the low overlap, the locking hook can unintentionally release from the locking cam, for example, when the internal pressure in the vessel increases. When opening the lid, the locking hook can jerky release from the locking cam, which liquid sample can be sprayed from the vessel.

The lidded container has a support device which stabilizes the lid in an intermediate position between a starting position pivoted away from the vessel opening by approximately 180 ° and a closed position at the vessel opening.

In one embodiment of the lidded vessel, two parallel fork tines extend between the hinge straps from the vessel flange, between which a gap parallel to the hinge straps is formed. The forks have locking edges. On the gap, a detent nose is aligned, which is connected at its tip with the cover flange and has locking projections on both sides of its root. The locking lug is aligned with their locking projections perpendicular to the cover flange. If the lid is closed in the direction of the vessel opening, then the latching nose enters into the gap between the fork tines and presses them slightly apart with their latching projections. When the locking projections come under the locking edges of the forks, they snap something together. If the lid is then released, the locking projections are retained by the locking edges and the lid stabilized in the achieved pivoting position. It is disadvantageous that the filigree forks in injection molding form flow path ends, which are difficult to vent due to their size. Air bubbles at the end of the flow path can lead to incomplete forks. However, a complete design of the forks is required for the pivoting position described above.

In a further embodiment, the support device has a latching nose, which is designed as a towering from the plane of the vessel flange hook. The locking lug is arranged between flexible middle portions of two parallel Schamierbändem, which are connected at one end to the vessel flange and the other end to the cover flange. The cover flange has a locking edge aligned perpendicular to its pivoting plane between the hinge straps. A flexibility of the locking lug or hinges allows when closing the lid, that the locking edge is lifted over the end of the latch. If you then let go of the lid, it is pressed due to the elasticity of the central portions with the locking edge against the locking lug so that it remains in this stable pivot position in which the vessel is open. To close the vessel, the lid is pivoted further and snapped with the locking hook behind the locking cam. This is disadvantageous that the achievement of the intermediate position can be hampered by the flexibility of the hinge straps. For example, if the user pushes against the outer edge of the cover flange when swiveling from above, he shifts the cover downwards due to the flexibility of the hinge straps. As a result, the locking edge meets at a low point on the locking lug and can only be pressed with great effort on the end of the locking lug.

A disadvantage of both embodiments is that the stability of the open position of the lid depends on the elasticity of the band sections. If the elasticity decreases, for example as a result of multiple closing and opening of the lid or due to heating or cooling of the vessel, the lid may become unintentional move out of the predetermined intermediate position and completely or partially close the vessel opening. This can affect the filling and emptying of the lidded vessel.

In a further embodiment, two parallel hinge bands are also arranged between the vessel flange and the cover flange, the flexibility of which is essentially concentrated on the narrowly limited area of a pivot axis. Vessel flange and cover flange are connected by another hinge strap, which is arranged between the hinge straps. The other hinged band has at one end a joint to the vessel flange and at the other end a hinge to the cover flange. Between these two joints, it is relatively thin, so that it is elastically extensible. After injection molding the lidded container, the lid is angled at about 180 ° from the vessel opening. In this starting position, the further hinge band is not stretched. If you now fold the lid about the pivot axis, so the distance between the joints increases and the other hinge strip is stretched slightly elastic until it is arranged on the pivot axis about which the lid is pivotable relative to the vessel. If the lid is then swiveled further, the further hinge strap contracts a little until it reaches its original length. This is the case when the lid is oriented at about 90 ° to the vessel opening. In this stable pivot position, the lid is stabilized by the further hinge band with respect to the vessel. If you close the lid, the other hinge is bent outwards. When the lid is closed, the latching hook in conjunction with the locking cam prevents the lid from opening. After unlocking the lid can be moved back to its stable pivot position or in the starting position back.

A disadvantage of this lidded container is that because of the narrowly defined region of the pivoting axis, the hinge straps do not permit any compensating movement during insertion of the inventive sealing collar into the vessel opening. As a result, the closing of the lid is difficult. In the embodiments with flexible middle portions of the hinge bands, however, allow the flexible middle portions a compensation, which facilitates the coaxial insertion of the sealing collar into the vessel.

The US 5,358,130 describes a one-piece container closure with means for keeping the lid open during dispensing. The closure comprises a cap with means for connecting to the vessel and a lid. The lid is connected to a support arm, which is connected via a hinge with the cap. The arm extends with the lid closed between two projections that stand up from the cap. Elongated ribs projecting laterally from the support arm are sized to engage the projections and hold the cover in an open position when the vessel is tipped over. When the lid is moved to the closed position, the ribs deform to pass between the projections. The projections have receptacles that receive the ribs without contact when the lid is in the closed position.

In this container closure, the clamping, which holds the lid in the open position may be insufficient or after use by repeated opening and closing and / or heating or cooling decrease, so that the lid is no longer securely held open.

In the lidded vessels according to EP 1 731 443 A1 . US 3,934,722 . US 5,270,011 . US 5,674,456 . US 6,398,067 B1 and WO 95/13137 A1 is the lid with the vessel connected in one piece via a hinge strap. These lidded containers have no support means for holding the lid in a defined pivoting position.

Based on this, the present invention seeks to provide a plastic lidded container for laboratory use, which can safely hold the lid in at least one position in which the lid does not close the vessel.

The object is achieved by a lid vessel with the features of claim 1. Advantageous embodiments of the lidded vessel are given in subclaims:

• ein röhrenförmiges Gefäß, das unten einen Gefäßboden, oben eine Gefäßöffnung und unterhalb der Gefäßöffnung an der Innenwand einen Dichtbereich aufweist,
• einen Deckel, der einen Deckelboden und einen von der Innenseite des Deckelsbodens vorstehenden Stopfen aufweist, der durch die Gefäßöffnung in eine abdichtende Position inden Dichtbereich einsetzbar ist,
• ein die beiden Gefäßteile Deckel und Gefäß integral schwenkbar miteinander verbindendes Bandscharnier und
• eine Halteeinrichtung zum Halten des Deckels in mindestens einer Halteposition, in der der Deckel nicht in die abdichtende Position eingesetzt ist, wobei die Halteeinrichtung mindestens zwei Eingriffsmittel hat, das eine Eingriffsmittel ein mit dem Gefäß oder Deckel fest verbundenes axiales Eingriffsmittel ist, das senkrecht zu der durch die Schwenkbahn des Deckels definierten Schwenkebene ausgerichtet ist, das andere Eingriffsmittel längsseitig auf dem Bandscharnier ausgebildet ist und die Eingriffsmittel durch ein Schwenken des Deckels in die Halteposition, das von einer elastischen Ausgleichsbewegung begleitet ist, in Eingriff miteinander bringbar sind.

The lidded container made of plastic for laboratory use has

• a tubular vessel having at the bottom a vessel bottom, at the top a vessel opening and below the vessel opening at the inside wall a sealing area,
• a lid having a lid bottom and a stopper projecting from the inside of the lid bottom, which is insertable through the vessel opening into a sealing position in the sealing area,
• a the two vessel parts lid and vessel integrally pivotally interconnecting hinge band and
• a holding device for holding the lid in at least one holding position in which the lid is not inserted into the sealing position, wherein the holding means has at least two engagement means which is an engagement means integral with the vessel or lid axial engagement means which is perpendicular to the is defined by the pivoting path of the lid defined pivoting plane, the other engagement means is formed longitudinally on the hinge band and the engagement means by pivoting the lid in the holding position, which is accompanied by an elastic compensation movement, are engageable with each other.

In the case of the lidded vessel according to the invention, the vessel and the lid are pivotally connected together in a known manner via a hinge hinge. The ribbon hinge may include one or more hinge bands that are at least partially flexible. The hinge hinge is similar to a living hinge, but may be flexible over a longer range in its longitudinal direction. A hinge with at least one hinge strap, which is flexible in the longitudinal direction at least in one area, facilitates the insertion of the plug into the vessel opening of a cylindrical vessel, since it allows a compensating movement.

In addition, the lidded vessel has a holding device capable of holding the lid in at least one holding position with respect to the vessel in which the lid does not close the vessel. In the holding position, the lid is not inserted with the stopper in the sealing position in the sealing area. To hold the lid in the holding position, the vessel or lid is connected to an axial engagement means. The axial engagement means is aligned perpendicular to the pivot plane defined by the pivotal path of the lid. The other engagement means is formed longitudinally on the hinge band. When, during pivoting of the lid, the axial engagement means and the engagement means formed longitudinally on the band hinge meet, an elastic deflection movement allows them to be moved past each other and engage in the holding position. The elastic deflection movement may, for example, consist in an elastic deformation of the axial engagement means and / or in a lateral deflection of the band hinge. The pivoting of the lid in the holding position succeeds regardless of the pivoting path, which executes the lid. The swing path of the lid is variable, as these have a flexible Band hinge is connected to the vessel to facilitate the insertion of the plug into the vessel, and not via a hinge with a well-defined pivot axis. The swing path of the lid is determined in particular by the height, the direction and the point of application of the force with which the user presses against the lid. This is not noticeable in the lidded container according to the invention by a strong increase in the force to reach the holding position.

In addition, it is advantageous that an axial engagement means is formed on the hinge band, so that material can be saved. The lid is held in the holding position by the elasticity of the hinge hinge. When the lid is pivoted to the holding position, the hinge hinge deforms elastically. Thus, the elasticity of the ribbon hinge keeps the engagement means in the holding position engaged with each other and prevents the lid from swinging further inadvertently.

The lidded container according to the invention is particularly advantageous by injection molding because engaged functional portions of the engaging means are not flow path ends that are last filled with plasticized plastic when the mold is filled so that air could collect therein which is difficult to evacuate through aeration of the mold. As a result, the decisive for the maintenance of the holding position functional areas can be made by injection molding particularly well and accurately.

According to one embodiment, from the one vessel part, a carrier projects laterally with at least one axial engagement means arranged thereon, and at least one engagement means, which can be brought into engagement with it, is formed on a longitudinal side of the band hinge adjacent to the carrier.

According to a further embodiment, the carrier is disc-shaped with parallel to the pivot plane of the lid extending side surfaces and has on the two side surfaces axial engagement means. Preferably, this carrier cooperates with a band hinge having two parallel hinge bands which receive the carrier between them.

According to a further embodiment, the axial engagement means on the carrier at least one directed perpendicular to the pivot plane of the lid locking receptacle and / or a latching projection.

According to a further embodiment, the axial engagement means comprise at least one shoulder on at least one longitudinal side of the band hinge. The shoulder can be brought into engagement with a latching receptacle and / or a latching projection of the carrier during pivoting of the lid.

According to another embodiment, the axial engagement means comprise at least one longitudinal edge of the band hinge and at least one latching projection of the carrier. The latching projection of the carrier can be brought into engagement with the longitudinal edge of the hinge hinge.

Furthermore, the object is achieved by a lidded vessel with the features of claim 7.

• ein röhrenförmiges Gefäß, das unten einen Gefäßboden, oben eine Gefäßöffnung und unterhalb der Gefäßöffnung an der Innenwand einen Dichtbereich,
• einen Deckel, der einen Deckelboden und einen von der Innenseite des Deckelbodens vorstehenden Stopfen aufweist, der durch die Gefäßöffnung in eine abdichtende Position in den Dichtbereich einsetzbar ist,
• ein die beiden Gefäßteile Deckel und Gefäß integral schwenkbar miteinander verbindendes Bandscharnier und
• eine Halteeinrichtung zum Halten des Deckels in mindestens einer Halteposition, in der der Deckel nicht in die abdichtende Position eingesetzt ist, wobei die Halteeinrichtung mindestens zwei Eingriffsmittel hat, das eine Eingriffsmittel mit dem Gefäß fest verbunden ist und das andere Eingriffsmittel mit dem Deckel fest verbunden ist, die Eingriffsmittel radiale Eingriffsmittel sind, die radial zur Schwenkbahn des Deckels ausgerichtet sind, von dem einen Gefäßteil seitlich ein scheibenförmiger Träger vorsteht, der am Rand mindestens ein radiales Eingriffsmittel aufweist, ein damit in Eingriff bringbares radiales Eingriffsmittel ein seitlich von dem anderen Gefäßteil vorstehender flexibler und elastischer Vorsprung ist und die Eingriffsmittel durch ein Schwenken des Deckels in die Halteposition, das von einer elastischen Ausweichbewegung begleitet ist, in Eingriff miteinander bringbar sind.

The lidded container according to the invention for laboratory use has

• a tubular vessel having at the bottom a vessel bottom, at the top a vessel opening and below the vessel opening at the inner wall a sealing region,
• a lid having a lid bottom and a stopper projecting from the inside of the lid bottom, which is insertable through the vessel opening into a sealing position in the sealing area,
• a the two vessel parts lid and vessel integrally pivotally interconnecting hinge band and
• a holding device for holding the lid in at least one holding position, in which the lid is not inserted into the sealing position, wherein the holding means has at least two engagement means, an engagement means is fixedly connected to the vessel and the other engagement means is fixedly connected to the lid in that the engagement means are radial engagement means radially aligned with the pivotal path of the cover from which a vessel member laterally projects a disc-shaped carrier having at least one radial engagement means at the periphery, a radially engaging means projecting therefrom and laterally more flexible from the other vessel member and elastic projection and the engaging means are engageable by pivoting the lid in the holding position, which is accompanied by an elastic evasive movement, in engagement with each other.

In the case of the lidded vessel according to the invention, the vessel and the lid are pivotally connected together in a known manner via a hinge hinge. The ribbon hinge may include one or more hinge bands that are at least partially flexible. The hinge hinge is similar to a living hinge, but may be flexible over a longer range in its longitudinal direction. A hinge with at least one hinge strap, which is flexible in the longitudinal direction at least in one area, facilitates the insertion of the plug into the vessel opening of a cylindrical vessel, since it allows a compensating movement.

In addition, the lidded vessel has a holding device capable of holding the lid in at least one holding position with respect to the vessel in which the lid does not close the vessel. In the holding position, the lid is not inserted with the stopper in the sealing position in the sealing area. For holding the lid in the holding position lid and vessel are firmly connected to radial engagement means. These are aligned radially to the pivot path of the lid. Of the one vessel part is a disk-shaped carrier, which has at least one radial engagement means at the edge. A radial engagement means engageable therewith is a flexible and resilient projection projecting laterally from the other vessel portion. When, during pivoting of the lid, the radial engaging means of the carrier and the flexible and elastic projection meet, an elastic deflecting movement allows them to move past each other and engage in the holding position. The elastic deflection movement may, for example, consist in an elastic deformation of the flexible and elastic projection and / or in a deformation of the band hinge in the pivoting plane. The pivoting of the lid in the holding position succeeds regardless of the operation by the user. This is due to the flexibility and elasticity of the projection and / or the hinge hinge. In this case, the projection is guided along the edge of the carrier. Thereby, the pivotal path of the lid is determined in an initial range of pivotal movement, regardless of the height, the direction and the point of application of the force exerted by the user on the lid to close this. The force exerted by the user does not make itself noticeable in the lidded container according to the invention by a strong increase in the force to reach the holding position.

In the case of the lidded vessel according to the invention, the vessel and the lid are pivotally connected together in a known manner via a hinge hinge. The ribbon hinge may include one or more hinge bands that are at least partially flexible. The hinge hinge is similar to a living hinge, but may be flexible over a longer range in its longitudinal direction. A band hinge with at least one hinge band, which is flexible in the longitudinal direction in at least one region, facilitates the insertion of the plug into the vessel opening of a cylindrical vessel, which allows a compensating movement.

In addition, the lidded vessel has a holding device which is capable of holding the lid in a plurality of holding positions with respect to the vessel in which the lid does not close the vessel. In the holding positions, the lid is not inserted with the stopper in the sealing position in the sealing area. For holding the lid in the various holding positions, at least one vessel part is fixedly connected to a series of engaging means arranged one behind the other in the pivoting direction of the lid. At least one other engagement means is connected to the other vessel part. When the one and the other engagement means meet when pivoting the lid, an elastic compensating movement allows them to be moved past each other and engage in a holding position.

Furthermore, the object is achieved by a lidded vessel according to claim 15. The lidded container made of plastic for laboratory use has

• a tubular vessel having at the bottom a vessel bottom, at the top a vessel opening and below the vessel opening at the inside wall a sealing area,
• a lid having a lid bottom and a stopper projecting from the inside of the lid bottom, which is insertable through the vessel opening into a sealing position in the sealing area,
• a the two vessel parts (lid and vessel) integrally pivotally interconnecting hinge band and
• a holding device for holding the lid in at least one holding position, in which the lid is not inserted with the stopper in the sealing position, wherein the holding device has at least two engagement means, one engagement means is fixedly connected to the vessel and the other engagement means with the hinge band or the lid is firmly connected and the engaging means by pivoting the lid in the holding position, which is accompanied by an elastic evasive movement, are engageable with each other in a positive engagement, whereby the lid on pivoting out of the holding position, not by an elastic evasive movement is accompanied, is prevented in both pivoting directions.

In the case of the lidded vessel according to the invention, the vessel and the lid are pivotally connected together in a known manner via a hinge hinge. The ribbon hinge may include one or more hinge bands that are at least partially flexible. The hinge hinge is similar to a living hinge, but may be flexible over a longer range in its longitudinal direction. A hinge with at least one hinge strap, which is flexible in the longitudinal direction at least in one area, facilitates the insertion of the plug into the vessel opening of a cylindrical vessel, since it allows a compensating movement.

In addition, the lidded vessel has a holding device capable of holding the lid in a holding position with respect to the vessel in which the lid does not close the vessel. In the holding position so the lid is not used with the stopper in the sealing position in the sealing area. The holding device securely holds the lid in the holding position because it has engaging means which positively engage with each other when the lid is in the holding position. This positive engagement prevents pivoting of the lid in both pivoting directions, ie both in the closing direction and in the opening direction. As a result, in the lidded container of the present invention, it does not matter that the band hinge has a permanent elasticity required to hold the lid in a stoppered position. In the lidded container according to the invention only a slight elastic evasive movement is required to bring the engagement means in positive engagement with each other when pivoting the lid. In this elastic evasive movement, the engagement means remove something from each other to be pivoted to an initial position, from which they can be brought into positive engagement with each other. In this initial position, the engagement means take more or less their original shape due to their elasticity, whereby the positive engagement is made. By the positive engagement of the lid is then safely in held the holding position. Unlike the prior art mentioned at the beginning, high elasticity is not important. The required elasticity does not have to fix the entire lid to a stop and prevent it from floating freely away from the stop. The evasive movement can be controlled by the contiguous contours of the engagement means when pivoting the lid.

It is not possible to free the lid by simply swinging out of the holding position. Rather, an elastic evasive movement is also required for this. The engaging contours of the engagement means may be configured so that the cover leaves the holding position only when a certain minimum force is exerted on the lid. As a result, an unwanted leaving the holding position is avoided.

The lidded container of claim 15, according to an advantageous embodiment of the features of the lidded container of at least one of claims 1 to 14.

For all lid vessels according to the invention, the holding position can be selected such that the vessel opening is free for introducing a dosing tip (eg pipette tip). Thus, the lidded vessel facilitates filling and emptying and helps to improve the workflow in the laboratory. The lidded container is particularly suitable for automatic filling and emptying in a dosing station or in a workstation for the treatment of liquids. Furthermore, the lidded container can be stored in a space-saving manner in the opened state, when the lid is aligned in the holding position with the lid base at an angle to the plane through the vessel opening.

The holding position may be selected to hold the lid in any orientation relative to the vessel that is not the closed position of the lid. Preferably, the lid is in the holding position about 45 ° to 135 ° away from the closed position. Further preferably, the lid is in the holding position about 80 ° to 110 ° away from the closed position. Further preferably, the lid is in the holding position about 90 ° to 100 ° away from the closed position. Preferably, the lid is about 95 ° from the closed position, especially for smaller containers (e.g., 2.0 ml or smaller). For larger vessels (e.g., greater than 2.0 ml), an angle of 90 ° is preferred.

The following embodiments apply to all inventions described above:

In principle, the band hinge and / or the engagement means may consist of the base material of the vessel and / or the lid. The design of the hinge and / or the engagement means, the elasticity can be influenced so that it ensures an elastic evasive movement. Further, it is possible to use for the hinge and / or the engagement means special materials that provide sufficient elasticity for the evasive movement.

According to a preferred embodiment, the band hinge on two parallel hinge straps, each connecting the lid to the vessel. The two hinges are flexible in at least one section. If the hinge straps are flexible only in one section, the flexible sections extend over the same distance region in the longitudinal direction of the hinge straps. Several parallel hinge straps guide the lid during pivoting better than a single hinge in the pivoting plane. In particular, they can avoid twisting the lid relative to the vessel.

According to a further embodiment, the carrier is disc-shaped with parallel to the pivot plane of the lid extending side surfaces and has on the two side surfaces on radial engagement means. According to a preferred embodiment, the radial engagement means radially to the pivot path of the lid and perpendicular to the pivot plane of the lid open latching receptacles. This embodiment of the lid vessel with a carrier favors the injection molding of the lid vessel with an injection mold without a slide, which is divisible for demolding of the lid vessel along a single axis.

According to a further embodiment, the edge of the carrier is rounded. A rounded edge of the wearer avoids damage to a user's gloves. For this purpose, rounded transitions between the engagement means and adjacent structures are also advantageous. Also advantageous are rounded transitions from locking receptacles to adjacent areas of the carrier and / or rounded latching projections and / or rounded latching edges.

The various stops allow the user to fix the lid more or less open in a holding position as needed.

According to a further embodiment, the vessel has, adjacent to the vessel opening, an insertion area for the stopper, which widens toward the upper edge of the vessel, and the sealing area below. As a result, the closing of the lid vessel is facilitated.

According to a further embodiment, the plug is hollow cylindrical. As a result, the plug is particularly flexible, whereby the closing and opening of the lidded vessel is further facilitated.

According to a further embodiment, the plug on the outer circumference has a circumferential sealing bead. As a result, the vapor-tightness of the lidded vessel is improved.

According to a further embodiment, the lidded vessel is produced by injection molding.

The lidded container according to the invention is made of one or more plastics. According to one embodiment, it is made entirely of elastic plastic.

According to a further embodiment, the lidded vessel is made of one or more polyolefins. Preferably, the lidded vessel is made of a polypropylene and / or a polyethylene. It is also possible to produce the lidded container with a stopper of various plastics, which has harder and softer segments, as in the US 2003/0102323 A1 which is incorporated by reference. The lidded container can be produced in particular by multi-component injection molding.

In this application, the terms "top" and "bottom" and "top" and "bottom" on the arrangement of the lid vessel in the closed state with vertically aligned, tubular vessel, the bottom of the vessel and the top of the lid is arranged.

The lidded vessel 1.1 of FIGS. 1 to 12 has a tubular vessel 2 with a circular cross section, which has a hollow cylindrical portion 3 at the top and a conical portion 4 at the bottom. At the bottom, the vessel 2 has a cup-shaped bottom 5. At the top, the vessel 2 has a vessel opening 6. Underneath it, in the hollow cylindrical section 3, there is a conically tapered down insertion region 7 and below a circular cylindrical sealing region 8.

At the top of the vessel 2 has a circumferential, radially outwardly projecting flange 9.1 in the form of a circular disk. At the flange 9.1 a locking projection 9.2 is formed.

Below the flange 9.1 is optionally arranged on the outer circumference of the vessel 2, a series of crenellated projections 10.1, which serve to support on the edge of a vessel holder.

The lidded vessel 1.1 has a lid 11 which has a lid bottom 12 and a stopper 13 projecting from the bottom of the lid 12. The plug 13 has a hollow cylindrical plug section 13.1. At the lower end of the plug portion 13.1, it has a circumferential, outwardly projecting sealing bead 13.2.

The lid bottom 12 protrudes laterally beyond the stopper 13 also. The cover bottom 12 has an approximately elliptical contour 12. 1 The extent of the cover bottom 12 in the direction of the main axis of the elliptical contour 12. 1 is limited by two approximately straight cover edges 12. 2, 12. 3 that run parallel to the minor axis of the elliptical contour 12. Fig. 6b ).

The outer edge of the lid bottom 12 is connected via a hinge band 14 with the upper edge of the vessel 2. The hinge band 14 is connected to the longer rectilinear lid edge 12.2. The hinge band 14 comprises two parallel, spaced-apart hinge bands 14.1, 14.2. ( Fig. 8 The hinged bands 14.1, 14.2 each have a stiffer first portion 14.11, 14.21 connected to the upper edge of the vessel 2 and adjacent to each a more flexible elastic portion 14.12, 14.22 and adjacent thereto a second stiffer portion 14.13 connected to the outer edge of the lid bottom 12 , 14.23.

Preferably, the hinge bands 14.1, 14.2 are integrally connected by injection molding with these vessel parts.

The hinge straps 14.1, 14.2 have between the flexible sections 14.12, 14.22 and the second stiffer sections 14.13, 14.23 inside each a shoulder 15.1, 15.2, the axial engagement means form ( Fig. 6b, c ). Between the hinge straps 14.1, 14.2 V-shaped locking receptacles 16.1, 16.2 are arranged on the two sides of a laterally from the vessel 2 projecting support 17th The V-shaped locking receptacles 16.1, 16.2 are each open at the top and laterally to the adjacent hinge bands 14.1, 14.2 out. They are from radial to the swivel path of the Cover 11 directed receiving edge 16.11, 16.12, 16.21, 16.22 limited ( Fig. 6c . 7b ). The locking receptacles represent further axial engagement means.

The carrier 17 comprises the carrier part 17.1, which protrudes radially from the edge of the vessel. The support member 17.1 carries above a narrow, disc or rib-shaped support member 17.2. The disc-shaped support member 17.2 is provided on the two flat outer sides 17.3, 17.4 with the locking receptacles 16.1, 16.2 ( Fig. 6 ). The upper edge 17.5 of the disc-shaped support part 17.3 is rounded.

Opposite the film hinge 14 of the stopper 13 laterally protruding part of the lid base 12 forms a lid projection 18. The lid projection 18 tapers towards the outer edge of the lid bottom 12. The lid projection 18 is bounded by the shorter rectilinear lid edge 12.3. Below the lid projection 18, a latching device 19 is arranged.

The latching device 19 has a flexible tab 20, which is connected at the top to the underside of the lid projection 18. The tab 20 comprises two parallel tab strips 20.1, 20.2, which are spaced apart. The tab strips 20.1, 20.2 are connected together at the lower end via a plate-shaped button 21, which projects laterally outwards. In the tab strip 20.1, 20.2, a recess 22 is above the button 21 is present. The recess 22 is bounded at the bottom by the inner upper edge of the key 21. Underneath, the button 21 on the inside has a chamfer 24 and below it a radius 25.

The key 21 is in the undeflected state, which in the FIGS. 4 and 5 is shown, arranged below a congruent or slightly larger cover recess 26 in the lid projection 18. As a result, a one-piece production of the Entire lidded vessel 1.1 allows injection molding by means of a simple tool.

According to Fig. 4 and 5 the lid 11 is locked in the closed state with the vessel 2. This is achieved in that the locking edge 23 engages under the flange 9.1 in a free area of crenellated projections 10.1, which forms the locking projection 9.2. The latching projection 9.2 has a radius 27 at the top and a bevel 28 underneath.

The lidded vessel 1.1 is in the in Fig. 6 and 7 shown, opened arrangement produced by injection molding. Due to the shape free of undercuts, the lidded vessel 1 can be produced by means of a simple injection molding tool without slides, the tool parts of which must be moved apart for removal from the mold only along an axis.

The lid 11 can by swiveling out of the in Fig. 6 and 7 closed opening position are closed. For this purpose, the user presses against the outside of the lid bottom 12. In an intermediate position according to Fig. 8 and 9 the lid 11 by constraining the shoulders 15.1, 15.2 in the locking receptacles 16.1, 16.2 can be locked. Here, the deflection of the shoulders 15.1, 15.2 laterally outwards and backwards by the flexibility of the shoulders 15.1, 15.2 and the strip areas 14.12, 14.22 allows. As soon as the shoulders 15.1, 15.2 reach the area of the latching receptacles 16.1, 16.2, they enter the latching receptacles 16.1, 16.2 due to the elasticity of the shoulders 15.1, 15.2 and the strip areas 14.12, 14.22. In this holding position, the shoulders engage behind the receiving edges 16.11, 16.21 and the lid 11 is held in this holding position by the elasticity of the hinge bands 14.1, 14.2.

To fully close the user presses again against the outside of the lid base 12. As a result, the lid 11 is pivoted further from the holding position. The shoulders 15.1, 15.2 emerge at the top from the openings of the locking receptacles 16.1, 16.2 and do not collide with the receiving edges 16.12, 16.22. The receiving edges 16.12, 16.22 can alternatively be arranged so that they are in the swivel range of the shoulders 15.1, 15.2 and the locking receptacles 16.1, 16.2 the shoulders 15.1, 15.2 record positively. The shoulders 15.1, 15.2 have to be expressed by taking advantage of their flexibility from the locking receptacles 16.1, 16.2 to zuzuschwenken the lid 11.

The locking receptacles 16.1, 16.2 are rounded so that they do not form sharp edges that can damage a user's glove.

The upper edge 17.5 of the disk-shaped carrier part 17.2 is rounded, so that the carrier 17 does not damage the gloves of a user.

The lid 11 pivots with the stopper 13 into the vessel opening 6, which is facilitated by the extended insertion area 7. Thereafter, the sealing bead 13.2 is introduced into the sealing area 8. The key 21 reaches its radius 25 on the radius 27 of the locking projection 9.2, as in Fig. 10 shown. Upon further pressing the lid 11, the tab 20 is deflected laterally outwards. Due to the flexibility of the tab 20 and bevels 24, 28 of the key 21 and the locking projection 9.2 this requires a slightly increased effort. When the latching edge 23 has reached the latching edge 29 of the latching projection 9.2, the flap 20 springs towards the receptacle 2 and the inner edge of the button 21 engages under the latching projection 9.2 (FIG. Fig. 4 . 5 ). As a result, the locking takes place and the lid 11 secured to the vessel 2.

To open the lid 11, the user presses from below against the button 21 so that it is deflected laterally, as in the Figures 11 and 12 shown. By pressing against the button 21, the lid 11 is moved out with the stopper 13 from the vessel opening 6 and opened. In the open position, the lid 11 is securely locked by the shoulders 15.1, 15.2 are engaged in the locking receptacles 16.1, 16.2 ( Fig. 8 . 9 ).

In principle, it is also possible with the cover vessel 1.1 described above to connect the carrier 17 rigidly to the edge of the lid 11 and to arrange the shoulders 15.1, 15.2 in the connection area between the stiffer first sections 14.11, 14.21 and the more flexible elastic sections 14.12, 14.22.

According to Fig. 13 a hinge hinge 14 has two parallel, spaced hinge bands 14.1,14.2. The hinge straps 14.1, 14.2 each have a stiffer first portion 14.11, 14.21 and adjacent thereto each have a more flexible elastic portion 14.12, 14.22 and adjacent thereto a second stiffer portion 14.13, 14.23. On the elastic portion 14.12, 14.22 sits in each case a thickening of material 14.14, 14.24, which control the targeted deformation of these sections.

Between the hinge straps 14.1, 14.2 a disc-shaped carrier 17 is arranged, which has a series of locking receptacles 16.3 in a rounded outer edge 17.5. The locking receptacles 16.3 are also rounded in vertical section.

Between the hinge straps 14.1, 14.2 an elastic latching tongue 30 is disposed on one side.

The stiffer first sections 14.11, 14.21 of the hinges are connected to the one vessel part and the ends of the second stiffer sections 14.13, 14.23 with the other vessel part. The first-mentioned ends are preferably connected to a lid 11 and the second-mentioned ends are connected to a vessel 2. The connection preferably takes place with the edge region of the cover bottom 12 and the flange 9.1.

Conversely, the ends of the lower stiffer sections 14.11, 14.21 and the latching tongue 30 with the vessel 2 and the ends of the second stiffer sections 14.13, 14.23 and the carrier 17 can be connected to the lid 11.

Furthermore, the latching tongue 30 is connected to the one vessel part and the carrier 17 to the other vessel part. Preferably, the latching tongue 30 is connected to the edge of the lid base 12 and the carrier 17 to the flange 9.1.

When pivoting the lid 1 from the 180 ° away from the vessel opening 6 pivoted position, the locking tongue 30 selectively engages in one of the locking receptacles 16.3. In this way, the lid 11 can be securely locked in various holding positions. On the way into the locking receptacles 16.3, the latching tongue 30 is guided on the rounded edge 17.5 of the carrier 17 (FIG. Fig. 13 ). On the way of the lid 11 of the locking receptacles 16.3 in the closed position, the latching tongue 30 is released from the rounded edge 17.3 ( Fig. 14 ).

In the embodiment of Fig. 15 are the hinge straps 14.1, 14.2 as in the embodiment of Fig. 13 executed. The carrier 17 is also connected disc-shaped with a rounded outer edge 17.3. The carrier 17 has at its two side surfaces 17.3, 17.4 respectively in the vicinity of the edge 17.5 a series of axial knobs 31. The knobs 31 form axial engagement means. The Knobs 31 are made of elastic plastic. Instead of the nubs 31 other projections may be provided with symmetrical or asymmetrical shape.

The hinge bands 14.1, 14.2 of the embodiment of Fig. 14 are like the hinges of the embodiment of Fig. 13 with a lid 11 and a vessel 2 connected.

When pivoting the lid 11 with respect to the vessel 2, the lid moves along a pivoting path, which is made possible by the hinge straps, wherein the material thickening 14.14, 14.24 contribute to a limitation of the pivoting path. The axial knobs 31 are arranged perpendicular to the plane through which the pivot track passes. Further, the knobs 31 are arranged parallel to the pivot axis of the lid.

When the lid is pivoted, the knobs are elastically compressed at the inner edges of the hinge straps 14.1, 14.2 and / or the hinge straps 14.1, 14.2 deviate somewhat elastically in the axial direction of the knobs 31 toward the outside. On the other side of the hinged bands 14.1, 14.2, the knobs 31 emerge and resume their initial shape. When pivoting the lid 11 thus knobs 31 come to rest against the inner edges of the hinge bands 14.1, 14.2 on both the upper and on the lower broad side of the hinge bands 14.1, 14.2. When just nubs 31 abut against the inner edges of the lower side and the upper side of the hinge bands 14.1, 14.2, the lid 1 is secured in a holding position. The series of nubs 31 allows securing the lid 11 with respect to the vessel in various holding position.
