CAP FOR ~ECEPTACLES, IN P~RTICULA~ BO~TLES
The invention relates to a cap for receptacles, in par-ticular, bottles made of plastic in a blow molding pro-cess which are filled and closed in the mold and have a neck on which the cap is placeable.
In plastic bottles with a neck which has an outer thread and is closed at its free end by a closure forming one piece with the neck, it is known to provide a piercer for piercing the closure on the inside and at the center of a cap screwed onto the neck. When the cap is removed after the piercing of the closure, the liquid in the bottle can then be delivered through the opening formed in the closure. Apart from the fact that a thread of the bottle neck and/or of the cap which is not of opti-mum shape or also a piercer which is not of optimum shape can cause the opening mzde by the ~iercer to PX-tend at an incline to the longitudinal axis, or after removal of a partial amount and subsequent screwing-on of the cap, a second opening is pierced, which results in the liquid flowing out in a direction deviating from the longitudinal axis, possibly at several points, which is troublesome, it depends on the pressure exerted on the liquid whether the liquid is delivered in larger or smaller drops or in the form of a jet. Furthermore, the size of the opening may change in the course of time if after removal of a partial amount of~the contents of the bottle, the neck is closed again by the cap and the piercer is introduced into the opening again. It is;
therefore, difficult to obtain the correct dosage of the -amount to be removed.
-: . .
,. , ;;'' '~ ~

21~03~
The object underlying the invention is, therefore, to enable problem-free removal of the liquid contents of bottles either in the form of single drops of a defined size or in the form of a jet. This object is accom-plished by a cap having the features of claim 1.
Owing to the section of the inventive cap being designed as dropper, the dosinq during delivery of the liquid contents of the bottle is not carried out by an opening formed by the bottle neck but by the dropper of the cap.
This dropper can be designed without any problems such that independently of the prevailing pressure it either forms drops of a reproducible size and then reliably e*cludes delivery in the form of a jet or brings about delivery in the form of a jet.
Insofar as the inventive cap is used for bottles, for example, ampoules which have a closure which first has to be provided with a flow opening, a piercer which pro-jects towards the bottle and in which the flow channel of the dropper begins is formed on an end face provided at the transition of the cap from the section receiving the neck to the section designed as dropper. The clo-sure can then be pierced by the piercer as in the known caps having a piercer. As the dropper carries out the dosing, it is, in this case, of no importance whether the opening is formed exactly at the center and co-axially in the closure and whether its size deviates from the set value.
210~3~
In a third embodiment, in order that the piercer can have a sharp point, the flow channel of the dropper has at least two end sections leading into the circumferen-tial surface of the piercer. These coMe to rest within the bottle neck when the cap is screwed completely onto the neck~
Very good reproducibility of the drop size and reliable prevention of jet-shaped delivery of the bottle contents are achieved with a flow channel of the dropper in which a section expanding conically in the discharge direction adjoins a cylindrical section. These sections are pre-ferably calibrated during manufacture by a calibrating mandrel.
It is also possible to design the cap such that it can be arranged on the neck with a close sliding fit.
However, as a rule, the section of the cap receiving the neck will be provided with an inner thread which corres-ponds in design to an outer thread of the neck.
In a preferred embodiment, a closure part removably placed on the section designed as dropper is provided to protect the flow channel of the dropper. This closure part is preferably designed as a pot-shaped hood with an inner thread which corresponds to an outer thread of the section designed as dropper. A plug which is sealingly introducible into the flow channel of the dropper can be formed at the center of the inside surface of the bottom of this hood.

The invention is explained in detail hereinbelow with reference to an embodiment illustrated in the drawing.
.
The single embodiment shows on an enlarged scale and partly in longitudinal section the embodiment in the state placed on the neck of a bottle before piercing of the closure of the neck.
A plastic cap desi~nated in its entirety 1 comprises, as shown in the Figure, a first, hollow, cylindrical sec-tion 2 serving to receive the neck 3 of a bottle whichin the embodiment has been made from plastic in a blow molding process and filled and closed in the blow mold, with the plate-shaped closure 4 closing the neck 3 forming one piece with the neck 3. The neck 3 of the bottle which may be an ampoule is provided with an outer thread 5. Between the bottle body 3' and the end of the outer thread 5 lying closer to the latter, the neck 3 has a cylindrical section 6, the outer diameter of which is chosen such that it is identical with that of the outer thread 5. Adjoining the end of the cylindrical section 6 facing the bottle body 3' is a toroidal ring 7 which projects radially outwardly to a slight extent over this section. The diameter of this toroidal ring 7 is slightly larger than the inner diameter of the zone forming the free end of section 2.
Section 2 is provided with an inner thread which cor-responds to the outer thread S of the neck 3 but does not extend into the zone forming the free end section.
2i)~
Adjoining section 2 on the side facing away from the bottle body 3' is a section designed as dropper 8 which has the same axis as section 2 and forms one piece with it. The section designed as dropper 8 is provided with an outer thread 9 and its free end is rounded off in semispherical shape. A conical piercer 10 is formed at the center of the inside end face 8' of the dropper 8 provided at the transition from section 2 to dropper 8, with its tip pointing into the interior of section 2.
End sections il of the flow channel extending through the dropper 8 which otherwise has the same axis as the piercer 10 lead into the circumferential surface of this piercer 10. Adjoining the end sections 11, the flow channel has a cylindrical middle section 12 and adjoining the latter a conical section 13 which expands to the ;~
semispherical end of the dropper 8. ~oth the middle section 12 and the conical section 13 are calibrated during manufacture by a calibrating mandrel. As the Figure shows, the diameter of the middle section 12 is considerably smaller than its axial length. This also applies to the conical section 13 which has a relatively small cone angle. In the embodiment it is approximately 8. The design of ~he flow channel and, in particular, its two sections 12 and 13 may also be chosen differently as it depends on the characteristics of the liquid, for example, its viscosity and surface tension as well as the size of the drops and on whether delivery is desired in the form of drops or a jet.

A pot-shaped protective hood 14 which like the cap 1 :. . . :
-- ; :~ . : . : .: .. . -, : . ~. - : :
:: : , - ., .. , ., :
. ' :, : .', consists of plastic is provided for covering the dropper 8. The protective hood 14 is provided with an inner thread corresponding to the outer thread of the dropper 8 and extends almost as far as the outside shoulder of cap 1 formed at the transition from section 2 to the dropper 8. As the Figure shows, a plug 15 is integrally formed at the center of the bottom of the protective hood 14 on the inside thereof. The plug 15 enqages the conical section 13 and seals it when the protective hood 14 is fully screwed onto the dropper 8.
If the bottle is marketed with the cap 1, the cap 1 is screwed onto the necX 3 so far that the free end of sec-tion 2 extends as far as the toroidal ring 7 of the neck 3, as the Figure shows. This position is easily recog~
nizable by the fact that when the cap 1 is screwed further onto the neck 3, the section 2 comes into con-tact with the toroidal ring 7 and hence an increased torque has to be applied. When the cap 1 is screwed onto the neck 3 as far as the toroidal ring 7, the piercer 10 is in contact with or almost in contact with the closure 4. When the contents of the bottle are to be removed, the cap 1 is screwed fully onto the neck 3.
As the piercer 10 thereby pierces the closure 4 and, in addition, the toroidal ring 7 has to be overcome, a clearly discernible increased torque has to be applied, which does not create any difficulties owing to the lon-gitudinal ~ibbing on the outside circumferential surface _ of section 2. When the piercer 10 has completely pierced the closure 4, the outer end face of the latter . . . . .

rests against the end face 8' of the dropper 8 carrying the piercer 10. The end sections 11 of the flow channel of the dropper also lead into the interior of the neck 3. The protective hood 14 now only needs to be screwed off to enable removal of the contents of the bottle in the form of single drops of a defined, reproducible size or, in the event the flow channel is designed for deli- :
very of the liquid in the form of a jet of a defined size, in the form of a jet.

The invention is explained in detail hereinbelow with reference to an embodiment illustrated in the drawing.
.
The single embodiment shows on an enlarged scale and partly in longitudinal section the embodiment in the state placed on the neck of a bottle before piercing of the closure of the neck.
A plastic cap desi~nated in its entirety 1 comprises, as shown in the Figure, a first, hollow, cylindrical sec-tion 2 serving to receive the neck 3 of a bottle whichin the embodiment has been made from plastic in a blow molding process and filled and closed in the blow mold, with the plate-shaped closure 4 closing the neck 3 forming one piece with the neck 3. The neck 3 of the bottle which may be an ampoule is provided with an outer thread 5. Between the bottle body 3' and the end of the outer thread 5 lying closer to the latter, the neck 3 has a cylindrical section 6, the outer diameter of which is chosen such that it is identical with that of the outer thread 5. Adjoining the end of the cylindrical section 6 facing the bottle body 3' is a toroidal ring 7 which projects radially outwardly to a slight extent over this section. The diameter of this toroidal ring 7 is slightly larger than the inner diameter of the zone forming the free end of section 2.
Section 2 is provided with an inner thread which cor-responds to the outer thread S of the neck 3 but does not extend into the zone forming the free end section.
2i)~
Adjoining section 2 on the side facing away from the bottle body 3' is a section designed as dropper 8 which has the same axis as section 2 and forms one piece with it. The section designed as dropper 8 is provided with an outer thread 9 and its free end is rounded off in semispherical shape. A conical piercer 10 is formed at the center of the inside end face 8' of the dropper 8 provided at the transition from section 2 to dropper 8, with its tip pointing into the interior of section 2.
End sections il of the flow channel extending through the dropper 8 which otherwise has the same axis as the piercer 10 lead into the circumferential surface of this piercer 10. Adjoining the end sections 11, the flow channel has a cylindrical middle section 12 and adjoining the latter a conical section 13 which expands to the ;~
semispherical end of the dropper 8. ~oth the middle section 12 and the conical section 13 are calibrated during manufacture by a calibrating mandrel. As the Figure shows, the diameter of the middle section 12 is considerably smaller than its axial length. This also applies to the conical section 13 which has a relatively small cone angle. In the embodiment it is approximately 8. The design of ~he flow channel and, in particular, its two sections 12 and 13 may also be chosen differently as it depends on the characteristics of the liquid, for example, its viscosity and surface tension as well as the size of the drops and on whether delivery is desired in the form of drops or a jet.

The protective hood 14 is provided with an inner thread corresponding to the outer thread of the dropper 8 and extends almost as far as the outside shoulder of cap 1 formed at the transition from section 2 to the dropper 8. As the Figure shows, a plug 15 is integrally formed at the center of the bottom of the protective hood 14 on the inside thereof. The plug 15 enqages the conical section 13 and seals it when the protective hood 14 is fully screwed onto the dropper 8.
If the bottle is marketed with the cap 1, the cap 1 is screwed onto the necX 3 so far that the free end of sec-tion 2 extends as far as the toroidal ring 7 of the neck 3, as the Figure shows. This position is easily recog~
nizable by the fact that when the cap 1 is screwed further onto the neck 3, the section 2 comes into con-tact with the toroidal ring 7 and hence an increased torque has to be applied.
