Definitions
- Container The invention relates to a container with a closure lid produced in the plastic injection molding process.
- the object of the invention is to make a generic container structurally simple, inexpensive to fill and yet effective closing function. This object is achieved by the invention specified in claim 1. Additional claims indicate advantageous developments of the subject matter of the invention.
- a container in the form of a tube of simple manufacture and high utility value is achieved.
- the procedure is such that a closure bottom is formed opposite the closure lid and that the closure bottom has a closable fill opening.
- the container can simply be turned upside down and optionally turned upside down by turning it over.
- the closure bottom stabilizes this area of the container. By stiffening this zone, the wall connecting the two ends of the container can be made quite thin.
- the closure bottom proves to be a sealing closure of this end of the container. It is furthermore advantageous that the filling opening can be closed by a closing part formed in one piece with the closing bottom. So there is a single component with respect to the closure bottom. Cheap it is also when the closing part is designed as a plug. This is technically manageable, in the interest of saving material the sealing plug is designed as a pot-shaped or dome-shaped, ie hollow plug.
- the closing part can be locked in its open position. The closure part can be held snugly on the top of the closure bottom.
- the closure base have a depression, assigned to the open position of the closure part, for engaging under the closure part with regard to
- the invention proposes that a handling edge of the closing part in the closed position can be made practically free of shadow gaps so that the corresponding adjustment can be made "Opening path" is not even recognized, so there is no optical-visual incentive for such manipulation. If, however, a refilling of the container is to be provided, a finger recess is taken into account in the closure base before the free end of the closure part. The closing part can be easily reached under and opened. Another advantageous feature is that the closing part has a latching means in its area engaging in the filling opening. The corresponding locking forces are to be selected so large that, e.g., using the container as
- the locking means is expediently implemented as a circumferential locking bead.
- the locking bead can sit both on the sealing plug and inside the filling opening, the respective counter-locking means being correspondingly in the form of a locking groove.
- the closing part is designed to be tapered. This reduces the printing area cross section. This is optimized if a collar protruding into the interior of the container is designed to interact with the closing part, which is designed in a correspondingly stepped manner. Forces acting against the periphery of the step are converted into a radial pressing component of the collar, which further promotes the sealing seat of the sealing plug.
- a head cover of the container which is largely closed on the end face, is integrally molded onto which the closure lid is integrally molded, with which an outlet opening in the end face can be covered, the opening cross section of the outlet opening corresponding to a fraction of the closure lid surface.
- the predominantly closed head cover of the container designed here in the manner of a tube stiffens the articulation area of the closure cover ("in the manner of a tube” means: application by deforming pressure on the at least partially flexible wall of the tube).
- the closure cap is articulated on an insert via an axle rod and, with the help of a control rod, opens and closes a valve body seated on the bottom of the insert as the actual closing member. It's a for a mass article too much effort '. - Despite the squeeze tube function, the closure cap does not come under mechanical stress to the extent that its integral gating suffers. On the other hand, a fairly large share is used for the formation of the sealing cover.
- the outlet opening on the other hand, which is in turn quite small (a fraction of the closure lid area) avoids any weakening of the largely closed top cover of the container. There is also the advantage that the number of parts is reduced to one. Assembly work and parts storage are no longer necessary. The vulnerability is also reduced.
- the closure cover connected to the head cover via a film hinge is injection molded onto the head cover in the region of a step-like offset lying in the direction of the film hinge.
- the step contributes significantly to the stiffening of the head cover in general and the hinge point in particular, but on the other hand the closure cover thus attached itself favors this effect.
- the wall cross-section is quite thin.
- the film hinge extends essentially in the shorter axis of the ellipse of the essentially elliptical cross-section of the container. It is also proposed that the height of the step-like displacement, ie step, the wall thickness of the
- Head cover as well as the cover corresponds. So there are no shrinkage zones favored by material accumulation. It is further proposed that the closure cover in the area of the step such is injection molded that in the closed state there is an essentially flat transition between an outer surface of the closure lid and an outer surface of the head cover not covered by the closure lid.
- the closure cover has an edge collar facing the side wall of the tube, which collar fits into an associated edge step of the head cover when the closure cover is in the closed position.
- the edge collar stiffens the closure lid.
- the thickness of the edge collar and the depth and width of the edge step are expediently coordinated in such a way that the edge collar nestles into the outer surface of the container to such an extent that excess protrusion is avoided, which increases the risk of the closure lid opening by accidentally touching a bag with carried utensils practically excludes.
- the invention proposes that the edge collar, in the closed state of the container, projects freely on the narrow side of the tube in a finger recess (as already mentioned with regard to the closure part in the closure bottom). Furthermore, it is favorable that when a tube outline is designed corresponding to an ellipse body in the area of the narrow sides, a cross-section which is essentially semicircular is formed. This can advantageously be used for profiling in that vertically extending bead lines are formed in the area of the transitions of the semicircular projections.
- the side wall formed on the head cover adjoins the side wall with a thickness corresponding to the head cover, and then the thickness of the side wall over a height which essentially corresponds to the height of the finger recess, to a lower wall thickness of the side wall transforms.
- the area of the container near the head cover is additionally stiffened due to the somewhat larger wall thickness in the sense of the stability of the container. Of course, this area can also collapse under the squeezing action in order to remove the contents, in order to even achieve a practically residue-free application of the contents, such as toothpaste.
- FIG. 1 shows the container according to the invention in a side view, namely upside down, ready for filling according to an embodiment
- FIG. 2 shows the container against the left-hand narrow side of FIG. 1
- FIG. 3 shows the top view of FIG. 1
- 4 transfers the container from the cup-ready position according to FIG. 1 to a position in which the head cover of the container points upwards, for example in order to be able to open the closure cover conveniently

- FIG. 9 shows a vertical section through the lid-closed outlet opening of the container
- FIG. 10 shows a vertical section in the area of the film hinge
- FIG. 11 shows a vertical section through the container in the injection or demoulding position of the closure cap and the closure base associated with the bottom with plug-closed filling opening
- FIG. 12 the bottom view of this
- FIG. 13 the container according to FIG. 11, now turned upside down in accordance with the filling
- FIG 15 shows a section of an automatic filling system, largely schematized.
- the container 1 shown in both exemplary embodiments is produced by plastic injection molding.
- PP is used.
- the state in which the container 1 is removed from the mold is shown in FIGS. 6 to 8 and 11, in which an integrally identical molded cover cap 2 assumes a connection position projecting from the container 1.
- the state of filling of the container 1 is shown in FIGS. 1 to 3 and 13 to 15.
- the head region of the container 1 points downwards and the bottom opening 3 of the container designed in the form of a tube upwards.
- the closure lid 2 is folded, that is, transferred into its closed position. After filling, the bottom opening 3 in the first embodiment is closed like a strip by pressing the peripheral sections of the opening 3 against each other.
- the closing strip is shown in FIGS. 4 and 5 and bears the reference number 4.
- a thermal closure is preferably used.
- the container 1 is largely closed on the end face according to a head cover 5 which in the position shown in FIG. 1 practically forms the cup bottom.
- the head cover 5 extends perpendicular to the longitudinal central axis xx of the container 1.
- the head cover 5 is basically elliptical see outline on.
- the corresponding cross-section continues into the tube body and changes into a cross-sectional shape that is increasingly boat-shaped due to the closing strip and ends in the rod-shaped closing strip 4.
- the whole of the elliptical floor plan is shown in FIG. 7 (namely supplemented by an arc line on the narrow sides of the elliptical cross section having a dash-dotted line type).
- Radial arc sections 8 which essentially form the broad sides of the container 1.
- the correspondingly larger radius of these circular arc sections 8 bears the reference symbol R2. It is four to five times larger than the radius R1.
- the width of the container 1 measured in the shorter ellipse axis zz goes twice into the length dimension measured in the longer ellipse axis yy, and this includes the protrusions 6 protruding from the plane in this plane.
- the transitions of the convex arch connections of the formations 6 to the circular arc sections 8 oscillate shaped wall cross sections. This leads to beads 9. These extend in the longitudinal direction on the container 1. They fan out in the direction of the closing strip 4 towards the narrow sides of the container 1.
- the corresponding wall condensation results in an advantageous stiffening of the wall of the compressible tube, which can be made very thin.
- the closure cover 2 is in one piece with the head cover 5 via a film hinge 10.
- Film hinge 10 currently runs in the shorter axis of the ellipse. It extends over the entire width of the head cover 5 there. It starts from the top of a step-like offset. The corresponding step bears the reference number 11.
- the head cover 5 assumes two different flat heights.
- the section of the head cover 5 to be overlaid by the closure lid 2 in the closing direction is, however, compensated for in terms of height in the closed position of the closure cover 2, so that a tilt-free, secure positioning is provided, as can be seen from FIGS. 1 and 13.
- the height H of the step-like displacement, or the step 11 corresponds to the wall thickness of the closure cover 2 and even that of the head cover 5.
- the cover cover 2 is adapted in terms of outline to the half of the head cover 5 to be covered, and is therefore not above the outline shown in FIG of the container 1 over.
- an outlet opening 12 in the end face or head cover 5 of the container 1 is covered.
- the opening cross section of the Aus Step opening 12 corresponds in area to a fraction of the cover surface.
- the outlet opening 12 thus does not represent any weakening of the head cover 5.
- it (12) is formed on a short, neck-like recess 13 of a peripheral section of the head cover 5 directed toward the container.
- the cup-shaped recess 13 can be seen particularly clearly from FIG. It lies in the plane of the longer ellipse axis yy.
- the inside of the pot forms a clip cavity 14.
- a stopper 15 of the closure cover 2 engages in the latter in a latching manner.
- the locking is achieved by rotationally symmetrical engagement between the two parts 13, 15.
- the stopper 15 is realized as a hollow stopper and runs in an arc path of the hinged closure cover 2 which is identical to the extension of the clip cavity 14 Head cover 5, for which purpose the cover 2 is molded on in the area of step 11 such that in the closed state there is an essentially flat transition between an outer surface a of the cover 2 and an outer surface b of the head cover 5 which is not covered by the cover 2.
- the latter is so balanced plan.
- the indentation 13 is in the vicinity of a so-called injection point 16, represented by an upper recess in the head cover 5 in the plane of the longer ellipse axis yy.
- the closure cover 2 has an edge collar 17 facing the wall of the container 1. This follows the outer wall contour of the wall, so it also forms one Continuation of the beads 9, which are designated 9 'on the edge collar.
- the oozing immersion of the edge collar 17 into the wall of the tube or the container 1 results from the formation of an edge step 18 in the area of the head cover 5.
- the two edge steps 18 fade away (see FIG. 9), since there the wall of the container 1 is withdrawn to form a finger recess 19.
- the edge collar 17, which continues in the same width or thickness, assumes a cantilevered, ie easily accessible, overhanging position in the region of this finger recess 19.
- the lower gripping edge of the section of the edge collar 17 which is matched to the convex curvature of the projection 6 there is designated by 20.
- the height of the trellis 17 covers a good third of the vertical length of the finger recess 19 from above, which finger recess 19 ends in a slightly convex arc at the zenith of the semicircular projection 6.
- the head cover 5 merges into a side wall 21 molded onto it.
- the thickness of the side wall 21 initially corresponds to the thickness of the said head cover 5.
- the wall thickness of the side wall 21 decreases significantly at a height which corresponds approximately to the finger recess 19. The decrease is continuous and goes up to about half the thickness of the side wall 21.
- the thinner, clearly dominating section in terms of length is referred to as the side wall 22.
- the container 1 also has the usual demolding
- 00423 ke 5 is approximately 1 ° .
- flanks 17 lie opposite counter flanks 23 00434 at the end of the peripheral edge step 18 there.
- the beads 9 can also be provided in larger numbers
- the container 1 gives up the more elliptical floor plan in favor of a long rectangular floor plan, but the circular arc sections 8 forming the broad side walls of the box 1 are essentially retained in order to narrow the convex corners into the now blunted ones Merging ends as narrow side walls of the cross-section.
- this container 1 forms or carries a closure base 24 opposite its closure cover 2, that is to say at the other end of the container 1. The is supported on the edge in the opening 3 of the container 1. It consists of the same material as the container.
- the corresponding edge defining the insertion depth of the closure base 24 is called 25 and consists of an outwardly directed projection of the wall of the container 1.
- the closure base-side support means is a flange 26. This is angled from a lying in the insertion direction of the closure base 24, the contour of Opening 3 in accordance with extending plug section 27 of the closure base 24.
- the closure bottom 24 has a closable fill opening 28. It is circular. Its central axis intersects the plane of the container 1 corresponding to the ellipse axis yy and is arranged outside the transverse center plane representing the shorter ellipse axis zz.
- the closure takes place by means of a closure part 29. The latter is integrally formed on the closure base 24.
- the actual sealing plug 31 is formed by a dome-shaped or pot-shaped retraction of the sealing part 29. Said sealing plug clearly stands out from the plane of the otherwise plate-shaped sealing part 29.
- Closure part 29 can be brought into a defined opening position, in which it is held against springback in the demolding position shown in FIG.
- the demolding position is shown in dash-dotted lines.
- the plate-shaped body of the closure part 29 is immersed in a contour-conforming bed 32 on the outside of the closure base 24.
- Lateral locking projections 33 which engage in the counter-locking means of the closing part 29 hold the closing part 29 in position.
- the sealing plug 31 protrudes beyond the flange 26 forming a setting edge and takes away the proper positioning capability from the container.
- the latched open position can be released after filling.
- the closing part 29 can be reached under in the region of its free end.
- This trough-like depression 34 extends in the plane of the longer axis of the ellipse and extends outwards to the inner edge of the closure bottom 24.
- the depression 34 is approximately finger-wide, goes inward into the central region of the closure plug 31 and leaves the one from FIG. 13 00526 visible access 35 for the willful digging
- the plug 31 sits sealingly in the filler opening.
- the closing part 29 or the sealing plug 31 00543 tapers towards a free end. It is about
- the collar 39 starts from an annular web 43 of the closure base 24 which is offset from the plane in relation to the general floor extension and into the interior of the container 1.
- the ring web 43 running parallel to the closure base 24, starts in the back of the wall section forming the locking groove 27. From there, the collar 39 also continues into a short, outgoing section.
- connection means that over the ring web 43 of the collar 39 a practically floating, swivel as best as possible on the contour of a circular arc line the plug 31 has adjustable mobility.
- the outward-facing section 44 of the collar 39 closes with its end face in the same plane as the flat section of the base area of the recess 42. This has a regulating effect between the sealing plug 31 and the overall collar 39/44.
- the filling pipe (FIG. 15) of a filling device is designated 45.
