Definitions

• the invention relates to a glass container having a base, a main body and a closure portion which surrounds an opening of the glass container and has, on its outer surface, fixing elements on the glass container side which can be brought into engagement with fixing elements on the closure lid side formed on a closure lid.
• the fixing elements on the closure sections of such glass containers are usually designed in the prior art as so-called “threaded worms,” which protrude radially from the outer surface of the closure section and are mechanically connected to the fixing elements on the closure lid.
• These threaded worms have a comparatively small cross-section and are therefore very sensitive to mechanical stress. This is especially true when glass-to-glass contact occurs in such glass containers.
• large rings are formed below the closure section or in the lower end section of the closure section in glass containers known from the prior art. Their outer diameter is selected such that the aforementioned threaded worms can hardly come into contact with other glass containers or their closure sections.
• such large rings detract from the overall aesthetic appearance of the glass containers and also cause considerable difficulties in production.
• the object of the invention is to further develop glass containers of the type described at the outset in such a way that mechanical damage to the closure sections and in particular to the fixing elements on the glass container side formed on the closure sections can be reliably excluded.
• the glass container-side fixing elements are designed as depressions in the outer wall surface of the closure section, and in that a raised surface portion of the outer surface of the closure section amounts to at least 20% of this outer surface. Due to the design of the glass container-side fixing elements as depressions in the outer almond surface of the closure section, as well as due to the large raised surface portion of the outer surface of the closure section compared to the prior art, mechanical damage to the container-side fixing elements or depressions is significantly reduced, whereby a so-called large ring below the fixing elements of the transition section can be completely dispensed with.
• the raised surface portion of the outer surface of the closure section is at least 30% of this outer surface.
• the engagement between the closure lid on the one hand and the closure section of the glass container on the other hand is made considerably easier if the recesses on the glass container side extend on the outer surface of the closure section up to its upper edge.
• the recesses on the glass container side each have the same shape or configuration, thus ensuring that correspondingly designed closure lids can be easily engaged with the closure section of the glass container in virtually any rotational position.
• the recesses on the glass container side are arranged at equal distances in the circumferential direction on the outer surface of the closure section, whereby this naturally also applies correspondingly to the fixing elements provided on the closure lid.
• each recess on the glass container side forms a stop for a fixing element on the closure lid side inserted into the recess.
• the inventive design of the closure portion of the glass container is particularly advantageous for glass containers in which the outer diameter of the closure portion is equal to or greater than the outer diameter of its main body.
• glass containers which are also referred to as tumbled glass containers
• mechanical contact between the closure portion and other glass containers occurs relatively frequently.
• the resulting mechanical stresses on the outer surfaces of the closure portions do not lead to damage to the fixing elements on the glass container side in the case of the inventive design of the glass containers.
• Such protection of the fixing elements on the glass container side is particularly advantageous, especially for reusable glass containers.
• the raised surface portion of the outer surface of the closure portion is approximately 40% to 60%, preferably approximately 50% of the outer surface. Since the raised surface portion of the outer surface of such glass containers essentially represents the contact zone between similar glass containers, the appropriate dimensioning of the raised surface portion of the outer surface ensures that no chipping occurs during contact between glass and glass.
• the raised surface portion of the outer surface of the closure section forms a continuous, uninterrupted surface, the risk of any chipping during contact between glass and glass is further minimized.
• the closure section is designed to extend over the entire circumference, ensuring that glass containers designed in this way can roll smoothly against each other, further reducing the risk of chipping.
• Figure 1 shows a side view of an embodiment of a glass container according to the invention.
• a glass container 1 according to the invention consists in the single Figure 1
• the embodiment shown consists of a base 2, a main body 3, which may be rotationally symmetrical, and a closure portion 4, which is arranged at the end portion of the main body 3 opposite the base 2.
• the closure portion 4 of the glass container 1 surrounds an opening 5 of the glass container 1, through which the glass container 1 can be filled and emptied.
• the glass container 1 can be closed by means of a closure lid (not shown in the figure) which can be releasably fixed to the closure section 4 of the glass container 1.
• the closure lid (not shown in the figure) has fixing elements (also not shown in the figure) on the inner surface of its cylindrical section.
• fixing elements 7 on the glass container side are formed on the outer surface 6 of the closure section 4.
• these fixing elements on the glass container side are formed as depressions 7 in the outer surface 6 of the closure section 4.
• These depressions 7 extend into a raised surface portion 8 of the outer surface 6 of the closure section.
• This raised surface portion 8 amounts to at least 20% of the outer surface 6 of the closure section and can also be significantly larger, as shown in Figure 1 is shown.
• the surface area 8 of the outer surface 6 of the closure section 4 is comparatively large, damage to the closure section 4, in particular to the fixing elements or recesses 7 on the glass container side, can be virtually eliminated.
• the forces acting on the outer surface 6 of the closure section 4 are distributed over larger areas of the outer surface 6, so that the risk of glass breakage or the like is very small.
• the recesses 7 extend slightly beveled to the circumferential direction of the closure section 4 in this circumferential direction.
• the recessed region of the outer surface 6 of the closure section 4 extends in the illustrated embodiment of the glass container 1 up to an upper edge 9 of the closure section 4 or of the glass container 1.
• the recesses 7 extending into the raised surface portion 8 of the outer surface 6 of the closure section 4 end at stops 10, against which the fastening elements on the closure lid (not shown in the figure) abut. When these fastening elements on the closure lid are in abutting contact with the stops 10 of the recesses 7, the closure lid is properly fixed to the glass container 1.
• the recesses 7 on the glass container side each have the same shape or configuration.
• a closure lid which has correspondingly designed fixing elements with the appropriate spacing, can then be placed on the closure section 4 of the glass container in virtually any rotational position and screwed into the recesses 7 on the glass container side with its fixing elements.
• the glass container-side recesses 7 are provided at equal distances from one another in the circumferential direction on the outer surface 6 of the closure section 4.
• the cross section of the glass container side recesses 7 in the direction of movement of the closure lid side fixing elements corresponds approximately to that of the Fixing elements on the closure lid side to ensure easy handling of the closure lid and at the same time proper fixation of the closure lid to the glass container.
• the design of the outer surface 6 of the closure section 4, which is virtually inverted compared to the prior art, in which the glass container-side fixing elements are formed not by raised surface sections on the outer surface 6 of the closure section, but by the recesses 7, provides special protection against mechanical damage to the closure section 4 in glass containers in which the diameter of the closure section 4 is at least equal to or greater than the diameter of the main body 3 of the glass container 1, since in glass containers 1 designed in this way, mechanical contact between the outer surface 6 of the closure section 4 and other glass containers or their closure sections frequently occurs.
• so-called tumbler glass which is designed without a shoulder and in which the diameter of the closure section is usually larger than that of the main body.
• the raised surface portion 8 of the outer surface 6 of the closure section amounts to approximately 50% of the outer surface 6 and is designed to be continuous, as can be seen from Figure 1
• This raised surface portion 8 of the outer surface 6 has, in the lower region, a portion extending around the entire circumference of the closure section 4, from which obliquely upwardly extending projections 11 extend.
• These obliquely upwardly extending projections 11 form the recesses 7 with the raised surface portion 8 arranged on the main body side of the closure section 4 of the glass container 1. Accordingly, the raised surface portion 8 of the outer surface of the closure section 4 forms a continuous, uninterrupted surface that extends over the entire circumference of the closure section 4.
