DESCRIPTION

Sterilization container, in particular for baby food

The invention relates to a sterilization container, in particular for baby food with a glass container with an upper opening, the glass container in the area of the upper opening presenting a lid reception in which a metal lid is fixed , a wrapping area being located below the cover reception and a source area leading down to the bottom of the glass container below the wrapping area.

In general, baby bottles generally use barrel-shaped bottles that have a lid reception with a screwed metal lid on their upper side. Below is a shoulder area, which in a rounded form starting directly below the cover reception leads to a cylindrical wrap area in which a label is placed. A source zone is formed with the cylindrical wrapping area that forms a bottom termination in the form of a fountain with a round bottom.

Containers of this type are optimized as disposable products in their form with respect to maximum stability, minimum volume and glass ratio and easy workability, as well as optimum handling during the production process. In addition, these bottles should be especially simple and practical for the user. Therefore, high stacking requirements of the sterilized full containers, the rolling behavior on conveyor belts, filling and sterilization machines, as well as possibilities of presenting the bottles in a sales shelf are raised.

These extreme requirements led to baby food being filled and generally offered in the described containers known as jars in bottles.

With the knowledge of the high requirements to the form of glass from the manufacturing process to the use of the bottle filled with baby food, the invention aims to perfect a sterilized container of this type that is also simply designated as little bottle

This objective is solved according to the invention with the features of claim 1.

WO 2010/136414 A1 shows a container with a large opening and a cap type cap. The diameter of the container is increased below the cap, and thus a shoulder is produced that has two opposite lines in section. The wrapping area between these two opposite lines is minimized to ensure a large cylindrical container area.

Bottles with a conical wrap and sheet area are known. However, the invention relates to sterilization containers. The sterilized containers have a larger mouth area than the bottles and therefore also have a larger lid on which major forces act during the sterilization process and during the stacking of the bottles.

In addition, jars with a conical wrap area are known. However, these jars have a glass lid that is in connection with the glass container through a disposable rubber. However, jars of this type are not suitable for stacking several bottles filled with one another or as a disposable merchandise.

A sterilization container is a container with a lid that is optimized for the sterilization process. The container must be able to be manufactured favorably, on the one hand, and meet the high requirements during the sterilization process, on the other hand. The glass container according to the invention has a container shape that makes it possible to empty the entire contents of the container with a spoon in a simple way and way. The conical wrap zone facilitates emptying by scoops, since the wrapping zone can be more easily reached with a regular spoon.

The cover reception can be a simple flange that cooperates with the tight cover, can present a thread, a bayonet closure or other special shape that cooperates with a lid. A lid reception designates respectively that upper edge of the glass vessel that cooperates with the lid.

The metal cover has at least one metal zone that cooperates directly or with a sealing material located in the middle or with the cover reception.

Surprisingly it has turned out that a conical wrap area offers not only advantages by emptying the container, but also the filling and labeling process can be easily mastered. The manufactured containers satisfy the especially high stability requirements in the full state and in the empty state. They can even be used without problems in automatic filling lines with extreme transport and filling speeds.

Due to the cooperation of the reception of the lid, metal cover and shape of the source and bottom area, the sterilized containers can be stacked in a simple way and are also up to the requirements that appear on a full stacked pale. The jars can be stacked on pales with 5 pales on each other.

In the case of a filling amount of 190 g, one can stack over another 10 layers per pale and therefore 50 full bottles.

In this regard, the conical wrap zone conducts the forces acting on the lid to the source area. Due to the taper the shoulder area can be reduced or even suppressed.

Another aspect of the invention therefore provides that the wrapping area begins directly below the cover reception. Consequently, the usual shoulder area is dispensed with, so that the forces acting on the cover are immediately transmitted to the wrapping area without a bend in the transition from the shoulder area.

In addition, the contents of the bottle become more easily accessible. Since the wrapping area begins directly below the lid reception, with a spoon the entire inner wall of the glass container can be scratched in a simple manner. It is advantageous that the wrapping area is conically configured.

Another aspect of the invention provides that the cover reception has a height of less than 8 mm, preferably less than 7 mm and especially preferably less than 6 mm. In this way the height of the lid area is greatly reduced and there is plenty of room for the shape of the glass container and for the labeling surfaces. In this respect, it is advantageous that the wrapping area begins directly below the cover reception, since in particular the surface for labeling can be brought up close to the cover. In addition, it is advantageous that the wrapping area is conical.

The wrap area between the lid and the source area has a conical shape whose wrap length is between 20 and 70 mm. This makes it possible to grab the glass in this area easily.

In addition, it is proposed that a label that also covers a part of the lid reception be placed in the wrapping area. The flat shape of the conical wrap zone allows a flat label to be applied that cannot be applied over a spherical area. In this regard, this label can be applied, if desired, not only in the conical wrap area, but can be extended even in the cover area and also be in contact there with the glass. If a narrowing is needed between the conical wrap zone and lid area, a heat shrink label can be extended in this narrowing and a paper tag can save the narrowing.

It is advantageous that the maximum outer diameter of the glass container is larger than the maximum outer diameter in the area of the lid reception. In this way the glass container receives an especially large volume and the costs for the metal lid are reduced.

Optimization of bulging volume is obtained since the maximum diameter of the glass container is located between the lower end of the conical wrap area and the upper end of the tray area.

In particular, for transport on conveyor belts it is proposed that at least two rings with a height of at least 2 mm be provided between the lower end of the conical wrap area and the upper end of the source area.

First of all for the sale of baby food, it is proposed that the maximum outside diameter of the glass container be greater than 50 mm and less than 80 mm and preferably less than 70 mm.

In order to empty the container even more easily, it is proposed that the inner side of the lid receptacle be converted without protrusion into the inner side of the wrapping area.

Tests with a view to stability and ease of handling have resulted in it being particularly advantageous if the maximum outside diameter in the lid receiving area is only 1 to 4 mm smaller than the maximum diameter of the glass container.

Especially good accessibility to the glass vessel is obtained since the maximum outer diameter in the area of the lid reception is between 50 and 75 mm and preferably between 55 and 65 mm. In particular, simple accessibility is obtained because the free inside diameter in the area of the cover reception is between 45 and 75 mm and preferably between 50 and 60 mm.

In the case of a sterilization container, the metal lid is kept in the container in general due to the depression in the full sterilized container. A possibility of re-closing the sterilization container can be obtained by folding the lid of the container, through which air can reach the container, so that the lid can be easily removed. However, the possibility of closing again can also be obtained because the metal cover has a screw closure.

In order to obtain the maximum possible labeling area and little cover area it is proposed that the metal cover has a height of less than 6 mm.

The metal cover does not have to be made entirely of metal. You can also present a closed opening with a plastic part or a plastic frame. This makes it possible to connect the lid differently and in a manner with the glass container.

Since the glass container should be stable as a disposable product, but it should also need little material, it is proposed that the glass container have a glass weight per full volume at the edge below 0.65 g / ml, preferably below 0.5 g / ml and especially preferably below 0.45 g / ml. The low specific weight of glass is made possible by the special shape of the glass container and lowers manufacturing and transportation costs.

An especially preferred height of the glass vessel is between 40 mm and 125 mm.

In a preferred embodiment, the source area has a rounded shape with a height of 8 to 24 mm and the bottom has a support surface with a diameter between 40 and 50 mm.

In order to satisfy the multiple requirements of such a mass product, it is proposed that the cover reception between the outer glass side and the inner glass side has a central glass plate that narrows towards the wrapping area as a truncated cone. While in the area of the envelope the shape of the glass narrows conically upwards towards the cover reception, for static reasons such a narrowing can also be expected in the area of the lid. But it has been proven that the indicated development of the central line is very advantageous both from the static point of view, and also with a view to the technical requirements in the cover area.

With a view to the internal stability of the sterilization vessel and with a view to the need for a large opening it is proposed that the bottom of the glass vessel has an annular support surface and the extension of the inner side of the lid reception, which narrows Conically towards the wrapping area as a truncated cone, cut this support surface. The inner side of the lid reception must not be completely flat and the support surface must not be exactly flat either. Therefore it depends that at least approximately the extension of this line on the inner side of the cover reception cuts the bottom in the area that serves as a support surface. In this way, technically the force introduced into the cover area is directed to the glass in the direction of the support surface.

In particular for the use of covers with a very narrow edge it is proposed that the cover reception has a stopper below a thread whose radius is greater than the maximum thread radius.

In order for the sterilization vessel to maintain a conical overall appearance, it is proposed that the lid reception has a horizontal upper bearing surface, which is located radially within the truncated cone extended upwardly from the outer side of the wrapping area. In this way it is possible to place a lid that preferably does not protrude and at least only insignificantly from the conical envelope curve of the glass container.

For static reasons it is intended that the truncated cone extended upwardly from the inner side of the wrapping area cut this horizontal upper bearing surface of the lid reception.

The objects of claims 8 to 12 are also essential for the invention regardless of the characterizing features of claim 1.

Figure 12 a detail of the container shown in Figure 11,

Figure 13 a section through the container shown in Figure 11, and

Figure 14 a detail of the container shown in Figure 13,

The container shown in Figure 1 is essentially composed of a glass container 2 and a metal lid (not shown). The glass container 2 has an upper opening 3 that is delimited by a lid reception 4. In the exemplary embodiment, this lid reception 4 is a thickening of the upper edge of the glass container in the form of a flange extending in the outer side of the glass container 2 around the glass container 2. Alternatively, the flange can also be configured as a thread.

Under the lid reception 4, a wrapping area 5 with a slightly conical but flat surface extends around the glass container. A label (not shown) can be placed on this wrapping area 5.

Under the wrapping area 5 is located the source zone 6 which extends from the wrapping area to the bottom 7.

The side view in Figure 2 shows that the cover reception 4 extends outwardly of the flange type in the upper area of the glass container 2. Below it runs a straight surface in cross section but slightly conical as the wrapping area 5. Below are two rings 8 and 9 that form a transition between the conical wrap zone 5 and the source zone 6. The bottom 7 has a central elevation indicated to points and strokes that leads to the glass container 2 being only on a surface in the area of an annular support surface 10.

The upper area of the glass container 2 is configured with an inner side without protrusion. This is achieved because the inner side 11 of the cover receptacle 4 becomes without protrusion on the inner side 12 of the wrapping area 5. In this respect, the inner side of the lid reception is configured downward slightly conically inward, while the inner side in the wrapping area 5 runs down slightly conically outwardly.

The container can be manufactured with different dimensions without leaving the base shape of the container in this way. Figures 5 to 10 show different examples of realization of containers 11, 12, 13, 14, 15 and 16 of this type. These containers have a diameter of approximately 66 mm. In Figure 5 the height is approximately 43.5 mm, in Figure 6 in approximately 59 mm, in Figure 7 in approximately 60 mm, in Figure 8 in approximately 84.5 mm, in Figure 9 in approximately 95.5 mm and in figure 10 at approximately 108 mm.

In these embodiments, the weight of glass is between about 65 g and about 130 g. Accordingly, the containers are manufactured with a full volume at the edge between about 105 ml and a full volume at the edge of approximately 275 ml. Therefore, the specific gravity of glass is between 0.62 g / ml and 0.44 g / ml.

The glass container 17 shown in Figure 11 has a large upper opening 18 which is configured in a lid reception 19. This lid reception 19 has a thread 20 with which a metal lid (not shown) is fixed. The upper end of the container is formed by an annular support surface 21. Underneath there is the cover reception 19 which has the thread 20 and a stop 22.

In this respect, the outer radius of the stop 22 is larger than the maximum outer radius of the thread 20.

A narrowing 23 extends under the cover reception 19 and below the wrapping area 24, whose outer side 25 is conically configured as a truncated cone.

The cover reception 19 has between its outer glass side 26 and its inner glass side 27 a central glass line 28, which along the circumference of the glass forms a truncated cone that conically narrows towards the wrapping area 24 .

The wrapping area 24 has an outer side 25 which is configured in the form of a truncated cone, which narrows upwards towards the cover reception. The truncated cone extended upwardly from the outer side 25 forms an enveloping curve 29, within which the upper horizontal support surface 21 of the lid reception 19 is located. Thus there are no areas of the reception beyond the truncated cone. provided by the wrap area.

In this regard, the horizontal upper support surface 21 is arranged so that a truncated cone 30 formed on the inner side 31 of the wrapping area cuts this support surface 21 with its extension directed upwards.

On the lower side of the glass container 17 is an annular bearing surface 32. This support surface 32 is in reference to the cover reception 19 so that the extension 33 of the inner side 27 of the cover reception 19, which conically narrows towards the wrapping area 24 as a truncated cone, cuts this support surface 32

5 In the case of different heights and filling volumes of the glass containers, the angle 34 also between the vertical and outer wall of the glass container in the wrapping area is approximately 3 °. This special form satisfies both aesthetic, as well as technical and static requirements with a view to the use of the container and its manufacture.
