Definitions

• the present invention relates to a screw cap for closing a container, which screw cap has a screw cap body and a guarantee tape device with a circumferential tape section and a tear-open tab connected to the same, which tape section has inner locking members on its inside, each with a ramp and a locking surface contains which container has outer locking elements arranged at its mouth along its outer circumference, which mesh with the inner locking elements when the container is closed, and which band section is connected to the screw cap body via first predetermined breaking webs.
• Such containers are closed for the first time in order to lock the locking members in place by a screwing movement between the screw cap and the container.
• the tooth-shaped locking members of the screw cap and the container begin to slide over one another, the locking members sliding or snapping over their ramp ramps into the locking position and a movement in the opening direction by mutual contact of locking surfaces Locking members is prevented.
• the locking members of the screw cap are arranged on a guarantee band, which is torn away from the body of the screw cap to open the container.
• the guarantee band is connected to the body of the screw cap by means of webs, which webs are broken by the force of the user when the guarantee band is torn off the screw cap.
• Containers in particular compressible containers and tubes, which are used to dispense e.g. Eye drops, or nose drops are determined, have an elongated pouring piece, a spout.
• the spout is initially closed at its tip and in order to open the pouring opening at the tip, the tip of the spout is separated by a knife. This results in a sharp edge at the spout opening, which can lead to injuries. This edge has hitherto been rounded off, inter alia, by the action of heat, with the risk that the passage at the pouring opening is too narrowed or even melted away.
• the aim of the invention is to provide a screw cap with a guarantee band device, in which when screwing the screw cap with the attached guarantee band there is no possibility of plastic deformation of the locking members, and nevertheless a secure locking of the screw cap on the container is ensured.
• a further aim is to provide such a screw cap, by means of which an edge which is dangerous to injury can be remedied at the pouring opening of the spout.
• the screw cap according to the invention is characterized by the features of claim 1. Advantageous designs result from the dependent claims. 97/42092 PC ⁇ 7IB96 / 00405
• FIG. 1 shows a bottom view of the screw cap according to FIG. 2,
• FIG. 2 shows a screw cap, partly in section and partly in a side view
• FIG. 3 shows a view from above of the upper part of a container shown in FIG. 4, and FIG. 4 shows the upper part of a container, partly in section and partly in a side view.
• the screw cap 1 shown in FIGS. 1 and 2 has a screw cap body 3 which is equipped with a guarantee tape device which, as the main parts, contains a circumferential tape section 4 and a tear-open tab 5 connected to the tape section 4. These parts are made of a suitable plastic. Along the circumferential band section 4, wedge-shaped locking members 6 projecting against the inside. Each locking member 6 has a ramp 7 and a locking surface 8.
• the band section 4 is divided into alternately arranged circular arc-shaped sections 14 and U-shaped sections 15, the legs of the U-shape pointing towards the inside of the screw cap 1.
• each U-shaped section 15 has a first leg 16 and a second leg 17, which legs 16, 17 are connected to one another via a base section 18.
• the circumferential band section 4 of the guarantee band is connected to the screw cap body 3 via first predetermined breaking webs 10.
• these first predetermined breaking webs 10 are weaker than the band section 4, so that when subjected to a force, these predetermined breaking webs 10 and not, for example, the band section 4 tear.
• FIG. 1 basically the second leg 17 [of each U-shaped band section 15 is connected to the screw cap body 3 via such a predetermined breaking web 10.
• the tear-open tab 5 runs along the outer side of the band section 4. At one end, it is structured in a structured manner by a toothed section 28 for easier gripping.
• the tear-open tab 5 is connected to the belt section 4 via a rigid transition piece 19, in particular to the first leg 16 of the U-shaped section 15 in question. Furthermore, it can be seen that the rigid transition piece 19 with the adjacent one circular section 14 forms an acute angle so that a tear-open notch 29 is formed.
• the tear tab 5 is further connected to some of the U-shaped sections 15 via further predetermined breaking webs 12, which further predetermined breaking webs 12 are in particular connected to a base section 18 of the U-shaped section 15.
• the further predetermined breaking webs 12 are weaker than the first predetermined breaking webs 10, so that when the pull tab 5 and the band section 4 are subjected to a force, the further predetermined breaking webs 12 tear in front of the first predetermined breaking webs 10.
• the inner locking members 6 are now not rigid, but arranged to be elastically evasive.
• a first spring member 11 formed by part of the band section 4.
• a further spring member 13 between a respective inner locking member 6 and the further predetermined breaking web 12, which is seen in the clockwise direction, and also the first predetermined breaking web 10 is formed by a part of the base section 18 of the adjacent U-shaped section 15. It can thus be seen that the inner locking members 6 can deflect elastically towards the outside.
• the screw cap body 3 of the screw cap 1 has an inner wall 20 and an outer wall 21.
• its outer wall 21 is corrugated, as indicated by reference number 30.
• An internal thread 31 is present in the lower part of the inner wall 20.
• a pin 22 protrudes into the interior of the screw cap body 3.
• An annular space 24 is thus formed in the zenith of the screw cap body 3, which is formed on the one hand by the peripheral wall 23 of the pin 22 and on the other hand by a section of the inner wall 20 is circumscribed.
• this inner wall 20 has a section 25 curved toward the pin 22.
• a straight surface section 26 adjoins this curved section 25, the sections 25 and 26 enclosing an at least approximately right angle with one another at their transition point 27.
• teeth 32 are still drawn. These teeth 32 serve to hold a tool during demolding, by means of which tool the screw cap 1 is rotated in order to be screwed out of the thread of the respective casting mold.
• This container 2 is intended, for example, to hold eye drops, is made from a suitable plastic and is designed to be compressible for dispensing the eye drops.
• the container neck is surrounded by outer locking members 9, which are designed as counterparts to the inner locking members 6 of the screw cap 1 and consequently also have a ramp 33 and an arm Retierflache 34 have. Above the locking members 9 there is an external thread 35, which was finally followed in front of the dispensing spout 36.
• the screw cap 1 is placed on the spout 36 and screwed on.
• the run-up ramps 7 of the locking members 6 of the band section 4 begin to run onto the run-up ramps 33 of the locking members 9 of the container 2. Because the locking members 6 can now deflect resiliently due to the spring members 11 and 13, plastic deformation of both the locking members 6 and the locking members 9 is excluded, it having to be noted that the locking members 6 and 9 in obviously also have a certain elasticity.
• the tear-open tab 5 is grasped and lifted away at the toothed section 28.
• the further predetermined breaking webs 12 tear. Since these are weaker than the first predetermined breaking webs 10, the latter are initially weakened If all, in the exemplary embodiment shown three, further predetermined breaking webs 12 are torn, the rigid transition piece 19 begins to pivot outwards, that is to say based on FIG. 1, by continuing to pull on the tear-open tab 5
• the connecting area between the first leg 16 and the band section there is now torn open by tearing notch 29.
• the first predetermined breaking webs 10 are torn in succession and finally the entire guarantee band, ie band section 4 and tearing tab see 5, be removed from the screw cap 1 so that it can be unscrewed from the container 2.
• the spout 36 is shown with a sharp edge 37 at the pouring opening 38. If the screw cap 1 is screwed onto the container 2, the pin 22 penetrates into the pouring opening 38. The edge 37 begins to run along the curved section 25 and is deformed inward, so that the upper surface area 38 only the pouring opening 38 comes into contact with the straight section 26. The spout 36 is thus plastically deformed at the pouring opening 38, so that there is no free edge which could cause injury.
