Oct. 25, 1966 M. GEISS COMBINATION BOTTLE AND BOTTLE STOPPER Filed Aug. 20, 1964 United States Patent 3,281 002 COMBINATION BOTTLE AND BOTTLE STOPPER Max Geiss, Habspergstrasse 6, Mullheim, Baden, Germany Filed Aug. 20, 1964, Ser. No. 390,824 Claims priority, applicatigg germany, Aug. 22, 1963, 3 Claims. (51. 215-52 For the packing of tablets, pills or the like, small glass bottles are frequently used which have a comparatively wide neck and a stopper made from flexible plastics or the like. To obtain sealing-tight closure with the stopper, it is known for the stopper part which extends into the bottle neck to be substantially oval-shaped or have one or more flexible strips arranged in a ring on that part of the stopper which bears against the inside of the bottle neck.

Although such stoppers generally give sealing-tight closure initially, the stopper will gradually be forced out of the mouth of the bottle unless it is secured in the closed position by external wire or cord, particularly if the stopper is provided with a resilient holder which projects into the interior of the bottle, bears against the contents and retains the latter resiliently.

According to the invention, the inside of the bottle neck or mouth is now formed with a substantially annular recess in the glass Wall such recess being so disposed that when the stopper is in the closed position it engages in said recess resiliently with elastic deformation of its material. Where an oval-shaped stopper is used which widens out somewhat from its lid part adjacen-t the neck of the bottle and then tapers again from a certain plane, the annular recess is advantageously so arranged in the glass wall that when the stopper is in the closed position its equatorial plane is situated in the region of the annular recess in the glass wall. If the stopper used has flexible strips arranged in a ring, the groove in the inner wall of the neck of the bottle is so arranged that the strips, or one such strip, bears by its edge against the top surface of the annular recess when the stopper is in the closed position. In either case the stopper so engages in the inner recess of the mouth of the bottle as to be reliably retained in the closed position and removable therefrom only if a perceptible resistance is overcome. The retention of the stopper in the closed position as obtained by the inner annular recess in the neck of the bottle according to the invention is very advantageous when the neck of the bottle widens out slightly, as is usually necessary for reasons of production. With such bottles in particular the conventional plastics stoppers tend gradually to work loose and escape from the mouth of the bottle.

The recess provided in the bottle neck is advantageous ly made as a complete ring although the neck may be formed with a series of sector-like recesses which functionally complement one another to form an annular recess in which the plastics stopper can engage.

A preferred embodiment of the principle of the invention is illustrated in the drawing, wherein:

FIG. 1 is a side elevation in partial section to approximately natural size showing a small wide-necked bottle according to the invention with a stopper, and

FIG. 2 is a section on an enlarged scale through the bottle neck and the stopper in the embodiment shown in FIG. 1.

The glass bottle shown in the drawing has a substantially cylindrical body 1, the top end of which has the slightly drawn-in neck 2. The top end of the neck 2 has an outer edge bead 3 which reinforces the bottle mouth and can also be used for the provision of a separate cord, wire or some other sealing means for the stopper. The

Patented Oct. 25, 1966 inner wall 2' of the neck of the bottle is formed with a substantially annular recess 4 which may have the crosssectional shape shown in FIG. 2.

The stopper connected to the bottle is of flexible plastic material which is deformable to a certain degree and comprises a lid part 5 which in the closing position bears against the end wall of the neck 2. In the embodiment illustrated, a substantially oval-shaped stopper part 6 projects into the bottle from the lid part 5 of the stopper. As will be apparent from FIG. 2, the stopper part 6 initially widens out from the lid 5 as far as the equatorial plane 6 and then tapers again as far the bottom edge 6" which is formed with notches.

The arrangement is such that when the stopper is in the bottle in the closed position the equatorial plane 6" is situated in the region of the annular recess 4 in the neck of the bottle so that the stopper part 6 engages the groove 4 with resilient deformation when the stopper is in the closed position. In this arrangement excellent sealing of the bottle by the stopper i obtained principally at the top end 4 of the recess 4.

When the stopper is lifted out of the closed position in the bottle (FIG. 2) the part which is near the equatorial plane 6 must first be forced back resiliently, for example by being bent at the mouth of the bottle at the edge of the lid part 5. The stopper is thus released from the groove inside the bottle mouth from which it can readily be withdrawn.

When the stopper is inserted into the bottle mouth, the engagement of the stopper part 6 in the recess 4 is clear- 1y perceptible when the closed position is reached.

If the stoppers have a ring of sealing strips on the stopper part, and when the stopper is in the closed position one of the strips, advantageously the top strip, lies behind the end edge 4 of the recess 4. To form the bottle glass with the recess for engagement of the stopper the bottle neck is advantageously heated to softening in which state the recess can readily be formed in the neck by impression with a suitable tool at the inner edge of the mouth.

I claim:

1. The combination of a glass bottle for the packing of tablets, pills or the like, and a hollow stopper which is in sealing-tight relationship in the bottle month, said stopper being made of flexible plastic, said bottle having a neck, said neck having an annular recess in the interior thereof and extending around said neck along a plane normal to the axis of said neck, said recess having a cylindrical outer portion therein, said stopper having a cap and a depending shank, said shank being of substantially constant thickness and having a substantially circular cross-section, said shank having a first outwardly tapered portion connected to a second portion of greater outward taper, said shank further including a third portion of large inward taper connected to said second portion, and a fourth portion of smaller inward taper connected to said third portion, said second and third portions extending into said annular recess engaging resiliently within said recess with elastic deformation without touching the cylindrical outer portion of the recess.

2. The combination according to claim 1 wherein the shank of said stopper engages against the top end face of said recess.

3. The combination according to claim 1 wherein the lower surface of said shank is provided with a plurality of notches therein.
