DETAILED DESCRIPTION FIG. 1 shows a thin-walled container with a container part 1, a substantially flat bottom portion 2 which merges into a wall portion 4 via a corner area, and a closing part 3. The material for the container is synthetic, preferably a polymeric material, and even more preferably a preferably recyclable plastic material. for example polystyrene, polypropylene, polyethylene, polyethylene terephthalate, or polyvinyl chloride. Criteria for material selection are that the material must be suitable for thermoforming under pressure or vacuum, and that it must be approved for use in food packaging,: nano: fira | »»>. 10 15 20 25 30 35 5186 637 W drugs etc., at least in cases where such areas of application are relevant. The container is thin-walled, with a wall thickness (t).

According to the invention, the closing part 3 comprises threads 5. In the preferred embodiment shown in Fig. 1, the threads 5 are arranged in a collar 10 in the upper part of the container. The collar here forms a downwardly directed portion which, at a distance, encloses the upper part of the container part 1, whereby the closing part 3 forms a portion which stiffens the container.

Between the collar 10 and the container part 1 is the upper surface 12 of the container, which may be flat and substantially horizontal, or may form an acute angle between collar 10 and container part 1. The threads 5 are hollow, since the container is made by thermoforming, which means that the hollow threads backs are visible on the inside / back of the collar. As a result, the threads 5 also become to some extent deformable, which can be positive for fitting and sealing between container and lid. The threads 5 are arranged so that each imaginary cross-sectional area through the collar 10 and parallel to a line of symmetry 9 usually comprises at least one thread goose 5A. However, in some cases the threads can be distributed in such a way that certain cross-sections do not pass through any thread goose. Between the gooses 5A, the collar 10 has a smaller diameter SB. The free end 13 of the collar has the largest diameter of the container.

The container is substantially, as when on the threads 5, rotationally symmetrical (which, however, is not necessary) about the axis of symmetry 9. The closing part 3 further has an annular sealing surface 7 which is continuously smooth or without discontinuities. In the preferred embodiment, the sealing surface 7 is rotationally symmetrically arranged about the axis of symmetry 9 and has a normal which is substantially parallel to the axis of symmetry.

The sealing surface 7 is further arranged between the wall portion 4 of the container part 1 and an upper wall portion 14, which upper wall portion 14 has a larger diameter than the wall portion 4.

IFig. Fig. 2 shows the lid 20 of the container in Fig. 1. The material in the lid is preferably the same as in the associated container. The lid 20 comprises a closing part 22 which in a collar-like portion is provided with internal threads 26, corresponding to the threads 5 in Fig. 1, and a substantially flat lid part 24 with a underside 24A and an upper side 24B.

The closure part 22 further comprises an annular portion / sealing surface 28 which is continuously smooth or without discontinuities and is arranged in a transition zone 30 between the lid part 24 and the closing part 22. Both lid part 24 and sealing surface 28 are rotationally symmetrically arranged about a symmetry axis 9. The sealing surface 28 consists of an annular portion which protrudes, i.e. forms a sealing sauce, below the underside of the lid part ann-s >> - || »:»> »10 15 20 25 30 35 513 637 ÉlÉï a Pl426 24A. This construction provides rigidity at the same time as it leads to an effective seal between the sealing surface 28 of the lid and the corresponding sealing surface 7 of the container.

The closure part 22 also comprises a substantially vertical wall portion 32, which is rotationally symmetrically arranged about the axis of symmetry 9 and arranged concentrically inside the outer, collar-like, threaded, part of the closure part, with the upper part 34 therebetween. The wall portion 32 advantageously merges directly into the annular portion / sealing surface 28, ie so that the lower part of the wall portion will form one side wall of the sealing ridge. It is then also advantageous that the wall portion 32 is substantially smooth, i.e. without deformation instructions, whereby a sealing force can be conducted directly down into the sealing surface 28, when a container is closed with the lid 20.

Fig. 3 shows the container according to Fig. 1 with the lid according to Fig. 2, a pair of aspects important for the seal being pointed out. The wall portion 32 of the lid then has a smaller radius than what the corresponding, upper, wall portion 14 of the container does on the corresponding vertical distance. This means that when the lid is applied to the container, a gap 40 is formed, between the wall portions 32 and 14, which facilitates the application of the lid 20 to the container 1. Complete sealing is achieved by the sealing surfaces 7 and 28, when the lid 22 by its threads 26 cooperating with the threads 5 of the container 1 press these against each other. In order for the sealing surfaces 7 and 28 to seal completely against each other, the wall portion 32 of the lid has a longer vertical extent than the corresponding upper wall portion 14 of the container, whereby the lid can be screwed so far down on the container that the sealing surface 28 of the lid is pressed together with the sealing surface 7 of the container, without risk of the upper edge 12 of the container coming into contact with the corresponding part 34 of the lid 20.

Fig. 4 shows an alternative lid 20 for the container in Fig. 1, which lid is designed so that the annular portion 28, i.e. the sealing surface 28 of the lid, projects below the underside 24A of the lid only in the area adjacent to the annular portion. On the other hand, the remaining part of the underside 24A of the lid, i.e. the more centrally oriented portion, is arranged at a level which is below the annular portion 28.

IFig. 5 shows a second embodiment of lid and container, where the annular portion / sealing surface 7 of the container 1 has a sealing sauce whose inner side wall merges directly into the wall portion 4 of the container part. In this embodiment, on the other hand, the lid 20 has a flat sealing surface 28 with a normal arranged parallel to the axis of symmetry 9. It is of course also conceivable that both containers and lids have sealing ridges arranged one against the other on 111: .iiør -ui »10 15 20 25 30 35 518 6837 Pl426. This figure also illustrates that it is possible to arrange lids and containers without any gap between their adjacent substantially vertical wall portions 14, 32.

Fig. 6 shows a third embodiment of lid and container, where the container is formed with a wall portion 4 which merges into a bottom portion 2, which bottom portion is substantially rounded, ie the container lacks a substantially flat bottom portion. The embodiment is intended to illustrate that the overall shape of the container is not important for the invention.

Fig. 6 also shows that an independent seal between the lid and the container can be obtained when the wall portion 32 of the lid has a smaller outward inclination relative to the axis of symmetry 9 than does the corresponding wall portion 14 A of the container on the corresponding vertical distance. This means that, when the lid is applied to the container, a downwardly tapering gap 40 is formed, whereby the wall portions 32 and 14A at the bottom are compressed more and more the further down on the container on which the lid is slid. This sealing variant is of course not limited to containers with a non-flat bottom. An advantage of having a slope difference between adjacent wall portions in connection with the sealing surface is that one can thereby avoid an early sealing interaction when the lid is applied, so that overpressure in the container can easily be avoided. Suitably there is a greater distance between the upper edge 12 of the container and the lid 34, as in Fig. 3, so that less precision in manufacturing is required and also otherwise better flexibility is obtained, except in cases where a double seal is desired.

Fig. 7 shows a fourth embodiment of lid and container, where the collar 10 of the container forms an upwardly directed portion, so that it constitutes an extension of the container. The collar 10 is then internally threaded to receive a lid. The collar 10 has a larger diameter than the wall portion 4 and the sealing surface 7 is arranged therebetween in the same way as in Fig. 1. The collar 10 can also (not shown) have a downwardly directed part which at a distance encloses the threaded part. The lid 20 is externally threaded, but still has a collar-like part 39 which is directed downwards from the upper part 34 of the lid and which encloses the threaded part at a distance, for the sake of stiffening and grippability. The lid 20 also has in this embodiment a wall portion 32 whose lower end merges substantially directly into the annular sealing portion 28.

Fig. 8 shows a fifth embodiment of lid and container, where the sealing surface 7 of the container is constituted by the upper surface 12 of the container. Thereby an upper wall portion 14, above the sealing surface, is missing. The collar 10 is otherwise designed in the same way as in Fig. 1. In the lid 20, the sealing surface 28 is constituted by an annular portion, which is placed radially outside, and preferably above, the underside 24A of the lid part. The sealing surface 7 of the container has> | »» s 10 15 20 25 30 35 518.63? PI426 a sealing sauce whose inner wall merges directly into the wall portion 4. The wall portion 32 provides a stiffening which in some cases is necessary for the dice between the container and the lid to be good. Figs. 9 and 10 show two further embodiments for obtaining a seal between lid 20 and container 1 at the top surface of the lid 12. In Fig. 9 this is achieved by arranging a canceled groove 41 in the surface 12 of the container 1. Correspondingly, the lid 20 is provided with an annular projecting portion 43 which, upon entry, is intended to be pressed into the groove 41, two annular sealing portions being obtained, since the wall portions of the groove 41 and the projecting portion 43, respectively, are slightly inclined. In addition, a similar sealing surface is obtained in transition between the upper surface 12 of the container and its wall portion 4, where the downwardly directed wall portion 32 of the lid will abut. In Fig. 10, the seal is provided by arranging the lid 20 in its upper annular surface 34 with a projecting portion 45 intended to cooperate with the upper surface 12 of the container part, which also constitutes the sealing surface 7 itself.

In Figs. 11 and 12 it is shown that container 1 and lid 10 can be formed with each small ear 47A, 47B in their free edges, the position of the ears being adapted so that they lie opposite each other when the container is closed. The two ears can then be sealed to each other by e.g. welding, whereby a seal is formed on the container. The two ears may further have a perforation line 49 to facilitate opening of the seal. Furthermore, Figs. 11 and 12 show that it is advantageous to arrange larger cans with rotary handles 51, 53.

The rotary grip 51 in the lid part 20 is formed as a number of launching devices, which form a kind of bubbles 51. Preferably, four such bubbles 51 are arranged in the lid part.

The opening and closing directions of the lid are also preferably imprinted. Correspondingly, recesses 53 are arranged in the bottom portion 2 of the container 1 which form torsional grips. Both the bubbles 51 and the recesses 53 are sized to be ergonomically correct to be gripped by the fingers.

Fig. 13 shows a variant of a container 1 with a lid 20, formed with rotary handles 51, 53, in accordance with the principles shown in Figs. 11 and 12. However, this embodiment is more suitable for smaller containers, wherein the rotary handles 51, 53 is not designed as separate elements but preferably on the lid consists of an elongate ridge-shaped part, which extends diametrically a substantial distance of the diameter of the lid and correspondingly the rotating grip 53 in the bottom portion of the container 1 correspondingly consists of an elongate depression, which also extends a substantial part of the diametrical distance, so that the ridge 51 can be gripped with a thumb grip and the recess 53 antun l0 15 20 25 30 35 518 637 10 Pl426 by placing one or a few fingers inside it, after which the lid can be easily threaded up. Furthermore, it is shown that in such a design no grip collar around the thread closure is necessary. Thus, the figure shows that the upper surface 34 of the lid part also constitutes its outermost part. The seal 7, 28 between container 1 and lid 20 is substantially formed in accordance with what is shown in Fig. 3, and is thus also arranged rotationally symmetrically in this embodiment. It is shown that the outer edge of the lid and the outer edge of the container part are coaxially arranged, which in some circumstances may be an advantage.

As already described earlier, the container and lid are manufactured by thermoforming, which is a very cost-effective method. In connection with thermoforming, a tool is also designed commercially, also for cost reasons, in such a way that several articles can be manufactured simultaneously. Thus, a relatively large sheet is fed to the tool which, after suitable heating, is moved to the tool containing a variety of molds, after which, with the aid of, for example, the vacuum plastic sheet is sucked into and assumes the contours according to the respective shape. Thanks to the forming method, optimal material utilization is obtained, i.e. approximately the same wall thickness is obtained everywhere, however, it should be understood that some thinning / displacement of material may occur, for example the corner wires often have a slightly smaller wall thickness (about 20% smaller) than adjacent parts since corner parts are furthest from the sheet at the start of forming. However, this phenomenon can be more or less eliminated in a known manner with the aid of special auxiliary tools which displace the plastic material in the desired manner during molding. There is a certain cooling for Stabilization of the designed article.

In the next stage, the sheet with the molded articles is ejected from the mold tool to be moved to the subsequent punching operation. Normally, ejection from the mold tool takes place with the help of so-called ejectors, which constitute separate units cooperating with the mold tool.

According to the present invention, said ejector tool can be eliminated by using the threads to eject the sheet. This is done by rotating the threaded part of each mold in the mold tool. This can be achieved by either rotating the entire mold surface or by rotating only the threaded part. The advantage of only rotating the threaded part is that the container part 1 can then be allowed to assume non-rotationally symmetrical shapes, for example hexagonal shape, which entails a certain stiffening. In order to produce articles according to Figures 11-13 - it is necessary to rotate only the threaded part since the rotary grip parts 51, 53 do not allow rotational symmetry. Furthermore, one gains the advantage that an ejection mechanism according to the above-mentioned principle provides a very large contact surface for the ejection mechanism, so that s i 10 l 15 20 ||>: | 518 637 ll Pl426 large force can be transmitted at the moment of ejection without damaging the article.

This makes it possible according to the invention that one can, for example, manufacture products which lack release, i.e. some parts of the article may have completely parallel walls. (for example be purely cylindrical) or even have a diverging cross-sectional area in the inward direction of the mold. This cannot normally be done because then large ejection force is required.

There is no risk of injury because the plastic material is still slightly warm and the thin plastic material itself is elastic.

In some cases, the good seal between the container and the lid can cause a slight overpressure to form inside the container when it is closed, whereby the container can have a slightly swollen appearance. In order for this not to be perceived as the contents of the container having fermented, the bottom portion can be designed slightly inwardly curved from the beginning, so that it becomes more flat when the container is closed. Alternatively, the container can be placed on an upwardly curved, supportive surface as it closes.

The invention is not limited to the embodiments shown, but can be varied within the scope of the following claims. It is realized, for example, that the number of common geese can vary within wide limits, from ranging from one to a variety. Furthermore, it is understood that many conceivable shapes other than hexagonal containers 1 can be manufactured according to the method according to the invention, for example triangular, star-shaped, etc. In addition, it is understood that the collar can be arranged to extend a substantial distance, whereby in an extreme case arranged around the lower part of the container.
