Description

Bottle opener.

The invention relates to an opener for 'plastic bottles, in particular for milk bottles.

Liquid foods, especially milk, are becoming more common today filled in plastic bottles, the plastic bottles mostly next to the milk filling system molded from the plastic granulate while it is still warm, d. H. so germ-free be fed to the filling system and after filling with the liquid food must be closed immediately so that the contents of the bottle remain sterile.

In order to be able to open the bottle, there is one at the head of the bottle neck Circumferential groove formed into which the knife can be inserted.

There is the disadvantage of slicing with an ordinary knife in the fact that this is usually not sharp enough to penetrate the plastic, the plastic deforms slightly when the knife is pressed against it and an ideal sliding surface forms and continues to escape when the knife is cut and at the same time the liquid food spurts out. It is therefore difficult to cut open again, because the pressure simultaneously squeezes the bottle and thus the liquid Food is squeezed out.

The invention is intended to eliminate this drawback and to create a device with the help of which an easy and effortless opening of the bottle is possible without that its contents spurt out.

The invention consists in that in one the upper neck of the bottle A lancet-shaped knife is mounted on the side like a bearing-like comprehensive handle, which is pressed into the bottle neck after placing the handle on the bottle neck and when turning the handle or the bottle the upper part of the bottle neck Separate cleanly all around with the bottle cap.

Another embodiment of the invention is the lancet-shaped knife stored in a guide part, the rear part of which is alesetDt and from which A bow-like spring is made of molded spring-loaded lugs the same molded plastic rests with the ends on abutments and pulls the knife back after letting go of the pressure piece.

In order to be able to grasp the handle better, this is on the circumference provided in a star-shaped arrangement.

Can be used as a closure around the severed piece of the bottle head To be able to make, the lancet-shaped knife is arranged so that it is the bottle head separates below the circumferential groove.

The advantage of the invention is that the bottle opener the Bottle neck includes bearing-like and therefore a crushing of the bottle neck when Prevents the lanceolate knife from being pushed in. This ensures that Do not squirt liquid food out of the bottle when pressing in the knife can. Due to the lancet-shaped design of the knife, it is easy to cut movable around the bottle neck, the bottle or the bottle opener being rotated can be, the bottle is expediently taken at the bottom so that this itself not squeezed and the content is squeezed out. The one on the handle molded approaches hold the guide part when the pressure piece is released in readiness firmly, and the molded spring pulls this pressure piece with the Knife holder and the knife back in a position in which the knife does not come out of the Handle protrudes and thus no involuntary injuries can occur. Another advantage is that the severed piece acts as a closure for the bottle is usable. All parts are manufactured as plastic injection-molded parts and can be assembled by simply plugging them together, thus inexpensive to manufacture.

The invention is shown in the drawing in an exemplary embodiment. It shows: FIG. 1 the top view of the bottle opener with operating instructions, 2 shows the side view of the bottle opener with a view of the pressure piece with spring, 3 shows the bottom view of the bottle opener with a section through the spring chamber according to Line III - III of FIGS. 4 and 4 with a section through the bottle opener Bottle head according to line IV - IV of FIG. 1, showing the mode of operation.

The handle 1 with the approaches 2 includes the bottle head with the conical shell-shaped part 3 bearing-like and prevents deformation of the bottle neck 6 when piercing the knife 5, which the bottle neck 6 through a Cut 7 separates from the bottle when turning the bottle or the opener. The lanceolate Knife 5 is mounted in a knife holder 8, the rear part 9 of which is offset is. Resilient lugs lo arranged on both sides prevent further springing back of the knife holder.

The molded at the end of the knife holder 9 pressure piece 11 is as a double-sided Spring formed, the ends of which are supported in abutments 12. The printed part is at the pressure point 13 held wider and is when pressed against the handle 1, such that it cannot be further depressed.

The separated bottle head 14 is on the bottle neck 6 as a closure can be put on and held by the circumferential groove on this.
