Description

The invention relates to a container for storage and Provision of stacked foil or sheet-like Materials from one of the stacked materials receiving tub with a bottom and adjoining closed side walls and a tub this at least partially surrounding, tightly sealing lid.

From the Japanese Utility Model Application 5-22380 is a such container known. The firmly surrounding the tub Lid has one on this by means of a film hinge attached flap for individually removing the foil or leafy materials. The flap, which is about a entire side edge of the container extends and to Tank center tapers down, lies on the lid and on the sink over a complicated, multi-curved sealing surface. The sealing contour requires a complex mold and also tends to leak.

Furthermore, from US 3,888,350, US 3,987,891 and DE 71 25 676 U comparable container known. Indeed These containers each have a cuboid structure with a front aligned perpendicular to the container bottom Tub wall. This makes it difficult to deploy stacked foil or sheet-like materials substantially.

The present invention is therefore the problem based, a repeatedly openable container for foil or to create sheet-like materials at a simple construction a high sealing function with respect to gases, Moisture and flavors guaranteed and providing the foil or sheet material supported.

This problem is solved with the characteristics of Hauptanspruches solved. For this purpose, the tub and the Sliding lid on both sides parallel to her Longitudinally parallel to each other guide elements. All Sidewalls of the tub have a sliding lid towards, the tub opening surrounding, closed tub sealing surface. The fourth - in sliding direction forward - side wall is formed curved as a removal lip. The sliding cover encompasses at least partially or partially three Sidewalls and the floor or equivalent Guide elements of the tub, with two of these side walls are oriented parallel to the longitudinal direction. The sliding cover is arched upwards from the tub and carries on his Inside a stop bar whose lower edge of the Front edge of the sliding cover out to the center of the lid to below the trough sealing surface - forming a stop - drops. In the sliding cover is a lid sealing surface formed with the container closed on the Can sealing surface rests.

Figures 1-11 show several sections and views of partially different, small and lightweight containers for storing and providing stacked sheet or sheet materials (1). The latter - also referred to as wafer - are shown in the figures only as a stacking block. The stack block (1) for example, has a floor area of approximately 1 "* 1 _^1/3". The height is about 5 mm.

The container width is about 73% of the container length, while the container height is about 18% of the container length.

In FIGS. 1-5, a first container variant is presented. The container consists of a trough (10) and a Sliding cover (30). The tub (10) and the sliding lid (30) enclose the stacking block (1) gas in the closed state, Moisture and aroma. The height of the tub (10) corresponds about 12% of the container length.

The tub (10) has a bottom (11) and three at least approximately perpendicular adjoining side walls (12-14). A fourth side wall, the so-called front wall (15) formed as a removal lip curved, wherein the curvature e.g. Part of a cylinder wall is. The front wall (15) goes tangentially out of the ground (11). Of the Radius of curvature corresponds to approx. 30% of the container length. By the flat rise of this side wall (15) can be the individual wafers e.g. with the help of the fingertip easily from the tub (10) push or pull.

All side walls (12-15) end up in one for example, flat pan sealing surface (18). The latter is in Embodiment aligned parallel to the ground (11), see. Also Figure 5. The upper edge width of Side walls (12-14) is in the range of Well sealing surface (18) approximately the same width. The upper Edge of the front wall (15) has about twice the edge width. The edge transition from the inner contour of the curved Front wall (15) to the sealing surface (18) is rounded here.

The two parallel side walls (12, 13) have in Floor area mirror-symmetrical guide grooves (21), the one 45 ° bevel (24) and a vertical surface (25). The Guide grooves (21) extend over the entire When length.

The sliding cover (30) consists of a curved lid part (31) and three adjoining side walls (42-44). The latter are largely at least in the tub area just. The side walls (42-44) are closed Container outside on the corresponding side walls (12-14) the tub (10) at least partially. The global Curvature of the cover part (31) represents e.g. one Sheath portion of a cylinder, the center line across to the longitudinal direction (9) and parallel to the bottom (11) below the tub (10) is located. The vaulting can also be part of one Ellipsoids or another curved space surface. Of the Radius of curvature of the embodiment is about 260% the container length. For example, in the front half of the Cover part (31) is a recessed grip (32) inserted. The latter has approximately the shape of a spherical dent, whose average radius is about 250% of the container length. The recessed grip (32) can on the sliding cover outside grooved, studded, roughened or with others Surface structures be equipped.

On the inside of the sliding cover (30) u.a. a stop web (35), cf. Figures 1, 2, and 4. He prevents the complete sliding out of the tub (10) the sliding cover (30) when opening the container. Of the Stop ridge (35) has in longitudinal section, cf. Figure 1 is the form a triangle whose tip is in the area of the leading edge of the Sliding lid (30) is located. The lower edge of the Stop ridge (35) falls to the middle of the lid down so far that they e.g. around a tub wall thickness under the tub sealing surface (18) sticks out. At maximum opening stroke comes the rear side wall (14) of the tub (10) with the back edge of the stop web (35) in contact, see. Figure 2, there is the stop bar (35) in the view shown.

In the extension of the stop bar (35) to the rear is located just before the rear side wall (14) on Cover part (31) a drive over stop cam (36). He is forward to the tub wall thickness opposite the Sidewall (14) offset. To the tub (10) out he has e.g. a hemispherical contour. According to Figure 1, the rear Tub side wall (14) with closed container between the rear lid side wall (44) and the Stop cam (36) clamped. This will be a prevents unintentional opening of the container. When opening and closing the tub (10) under elastic Deformation of both container parts (10, 30) over the Sliding cam (36) pushed away.

The side walls (42, 43) of the sliding cover (30) comprise the side walls (12, 13) of the trough (10) are c-shaped, cf. Figures 5-7. Above the pan sealing surface (18) they are - when the container is closed, a flat lid sealing surface (48) forming - widened inwardly so far according to FIG. 5 that they cover the tub sealing surface (18). This broadening is located on the rear side wall (44), cf. Figures 1, 2, 10 and 11. Also, the leading edge of Sliding lid (30) is in the area of the tub front edge as Part of the lid sealing surface (48) shaped.

At their lower edges, the side walls (42, 43) mirror-symmetrical guide webs (51), each over a 45 ° bevel (54) on the corresponding guide groove (21) rest against the trough (10).

The container parts (10, 30) consist of an elastic Plastic that is preformed so that the Side walls (42, 43) of the sliding cover (30) below Clamping force on the Wannenseitenwandungen (12, 13) abut. By contacting each other 45 ° bevels (24, 54) of Container parts (10, 30) results in a clamping force that the Cover sealing surface (48) and the tubing sealing surface (18) below Forming a sealing joint (8) press each other.

Possibly. can the plane of the sealing joint (8) to the longitudinal direction (9) include an acute angle, cf. FIGS. 12 and 13 the trough (10, 110) at the rear has a lower sealing height has as front. In this case, the lie down Sealing surfaces (18, 48) only on the last millimeters of Container closing movement on what the friction load of Sealing surfaces (18, 48) reduces. This will make thin, frictional and sealing coatings of the sealing surfaces possible.

The front edge of the sliding cover (30) is shaped so that when the container is open - transversely to the longitudinal direction (9) - slightly curved down. When closing the container slides the sliding lid leading edge to form a Sealing force on the tub leading edge.

FIG. 6 shows a sealing joint (8) with lip seals. For this purpose, on the side walls (12-14, 42-44) of Container parts (10, 30) sealing lips (57, 58) forming, after arranged inside protrusions. In the embodiment the upper sealing lips (57) are stiff, while the lower (58) elastic - against this pressing - trained are.

FIGS. 9-11 show a container variant, the sliding cover (130) the tub (110) in partial areas the container cross-section completely - as with a conventional matchbox - by means of a Cover bottom (180) surrounds. The lid bottom (180) extends extending from the rearward side wall (144) forward to to the front end of the tub bottom (11). By using the lid bottom (180) become the functions of the separate Guide elements (21, 51) of the previously described Container variant through the side walls (12, 13, 42, 43) and the lid bottom (180) replaced.

In the lid base (180) are, for example, two Recesses (181, 182) which cover the lid (180) in two Divide floor bars (183, 184). The rear recess (182) continues far into the side wall (144), cf. Figure 10. Both recesses (181, 182) have one here rectangular contour. Other contours are also conceivable.

At the tub bottom (11) are a rear stop cam (136) and a front stop web (135) formed. The front Stop bar (135) prevents complete Pushing the tub (110) out of the sliding cover (130). For this purpose, the stop web (135) lies on the front Bottom bridge (183) blocking, cf. Disabling function of Stop bar (35). The stop web (135) has in Longitudinal section largely a triangular contour, cf. characters 10 and 11. The top of the triangle is to the rear oriented. Thus, during initial assembly, the tub (110) under elastic deformation of both container parts (110, 130) be pushed into the sliding cover (130). Rear Stop cam (136), he has the function of a Lock stop, lies with closed container at the rear edge of the rear floor land (184). in the Longitudinal section, cf. Figures 10 and 11, he is front and rear rounded off, taking it to the back - to facilitate Initial assembly - bevelled. The bevel is visible in the bottom view of Figure (9) in a drop contour.

The container of Figures 1-5 and 9-11 allow a simple one-hand operation. This is the container between the index finger and the thumb in the hand. The rear side wall of the sliding cover (30) shows to the inside of the hand. The thumb lies on the recessed grip (32) on. The tub (10) lies on the slightly curved Pointing finger up. Will now - with held container - the The thumb is pulled back from the index finger, the Sliding lid (30) moved back to the opening shock (35). With the thumb tip can now - without changing the principle hand position the top sheet of the Stacking blocks (1) over the front edge of the tub (10) be pushed to it - after a corresponding Arm movement - to take over with the tongue.

To close, while maintaining the principal Hand gesture of thumbs forward over the curved Index finger pushed until the locking stop (36) locks. The container is closed again aroma-tight.

The container whose sliding cover (130) the Lid bottom (180) has between the thumb and the Index finger tip and the index finger tip held. The Forefinger point grips the pan (110) through the Recess (181).

The opening movement can be achieved by means of a spring (71) be supported, cf. Figure 8. This is in the back Area of the tub (10) a multiply folded Biegefeder (71) arranged. The spiral spring (71) is included closed container from the rear extended Side walls (12, 13) and the likewise extended Frame (11) framed. She is for example at the Outside of the rear side wall (14) glued. in the Cover part (31) is located in front of the rear side wall (14) a latching stop (72) by a Upward movement releases the spring-assisted opening stroke. These are by hand force the lateral Lid side walls (42, 43) elastically deformed so that the lid part (31) bulges slightly upwards.

FIG. 7 shows a solution variant with the aid of which so-called secondary packaging can be saved. This is to Attaching a sealing film (65) in the tub (10) in the area the pan sealing surface (18) a deeper circumferential Paragraph (61) arranged. The amount of the paragraph (61) is maximum of a few tenths of a millimeter. The paragraph width corresponds about half of the wall thickness of the side walls (12-14).

On a e.g. level sealing surface (62) of the paragraph (61) the sealing film (65), the tub (10) completely sealing, attached. In Figure 9, the sealing film (65) - from below - shown in phantom. It sticks out with a tear-off tab (66), for example, asymmetrically over the leading edge the tub (10, 110) over. The sealing film (65) has in addition a tear-off embossing (67). It is in FIG. 9 Drawn double-spaced and lies with open Container directly in front of the front edge of the sliding cover (30, 130). When removing the held on the tear-off tab (66) Sealing film (65), tears the latter at the tear-off embossing (67) completely off.

In any case, at least the trough (10, 110) consists of an injection-moldable material which hardly absorbs aromas, for example of essential oils, eg polypropylene, polyethylene naphthalene, polyethylene terephthalate, or comparable materials. Possibly. For example, the material can be coated with SiO _x, at least on the inside of the container, in order to ensure an extensive aroma-tightness. The sealing film (65) consists for example of aluminum-coated polyvinyl chloride, polyvinylidene dichloride or comparable materials.

Figures 14 and 15 show an embodiment similar to the beauspruchten container with a sliding cover (10) and a container in which in the side walls (12, 13; 43) curved or inclined guide elements (21, 51) are arranged. For example, the Sliding lid walls (42, 43) a projecting Guide profile, while the pan side walls (12, 13) have corresponding guide grooves. In this container is the lid sealing surface (48), as well as the container of the Figures 1 - 3, arranged parallel to the bottom (11).

In the straight, oblique to the cover sealing surface (48) aligned guide elements, in Figure 14 as dash-dotted lines shown, move away at a Opening stroke the sealing surfaces (18) and (48) proportional from each other. The sealing surfaces (18) and (48) move parallel to each other. The for opening the container according to Figures 12 - 15 necessary operating force is after overcoming the breakaway force of the first millimeter of the Opening stroke by eliminating the sealing surface friction considerably smaller than in the containers according to the figures 1 - 11th

In the curved guide elements (21, 51) moves the Trough (10) opposite the sliding cover (30), for example on a circular path. The center of the circular path lies in the extension of the inner contour of the side wall (44) below the sliding cover (30). The radius of the circular path corresponds e.g. about 250% of the container length, so the Front end of the guide elements (21, 51) - related to the Pan (10) - at the transition between the bottom (11) and the front side wall (15) ends. In the Guide elements (21, 51) are the stops for the Opening stroke arranged.

Due to the curvature of the guide elements (21, 51) results easy accessibility after opening the container of the tank contents (1).
