'7 Claims.

This invention relates to closures for containers and particularly to closures for bottles provided with means for indicating whether or not such closures have been opened for removal of the contents.

One of the principal objects of the invention is the provision of a fitting having a nonreplaceable diaphragm which may be broken, perforated or removed to obtain access to the contents of a container.

Another object is the provision of a fitting having an inner seal covered by a cap or stopper and adapted to be readily broken, perforated or re- 'moved after removal of said cap or stopper.

7' Another object is the provision of a fitting having means for securing it to a container, the relative strengths of the fitting and the securing means being such that the fitting cannot be removed from the container. without destruction.

Another object is the provision of means for inhibiting the application of a cap or stopper to a container from which my fitting has been removed. 7

Another object is the provision of a molded fitting for a bottle neck having a nonreplaceable diaphragm molded thereto.

Another object is the provision o-f a fitting having a diaphragm molded thereto and astopper adapted to be removed after said diaphragm has been broken away.

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawings illustrating preferred embodiments of my invention and wherein similar reference numerals designate similar parts throughout the several views.

Figure XI is a front elevational view, with parts broken away and parts in section, of a bottle equipped with still another form of the closure of my invention; and

Figure XII is a front elevational view of the neck of a bottle equipped with still another form of the closure of my invention.

Referring to the drawings in detail, I have shown my closure applied to a bottle or flask l, which may be of any desired shape and material. In the form shown in Figures I and II, the neck 2 of the bottle is provided with inwardly projecting protuberances 3 to prevent the mouth from being tightly fitted with a. stopper or cork in case an attempt is made to use the bottle without my 40 fitting. The exterior of the neck is provided with circumferential grooves 4.

Fitted over the mouth of the bottle is an annular member 5 provided with inwardly extending beads 6 engaging the grooves 4. The annular member 5 may be made of metal, porcelain, or glass, but it is preferably made of urea-formaldehyde resin or othermolded material. Before the annular member is pushed into place on the upper end of the neck 2, a coating of cement is applied 5 to one or both of the surfaces of the neckand annular member to be engaged, the character of the cement preferably being such that when it has set or hardened the annular member 5 cannotbe removed from the neck without destroying either the annular member or breaking the bottle neck. The member 5 may, if desired, be made more frail by one or more outer grooves or furrows such as is shown in Figure I.

At the upper end of the annular member 5 and closing the opening therethrough is a seal 7, preferably of foil, or thin sheet metal capable of being easily cut or torn, or of parchment or the like. The seal 1 is provided with a downwardly extending fiange 8 which is molded into the material of the annular member 5. If desired, an opening 9 may be left in the flange 8 to facilitate insertion of a pointed instrument or finger nail under the seal. The seal also may be scored adjacent its periphery so that it can be easily torn away.

Surmounting the annular member 5 is a cap it provided with internal screw threads engaging complementary external threads on the upper end of the annular member 5. Lying within the cap I0 is a liner or gasket M, which, when the cap is screwed down upon the annular member 5, is tightly compressed between the cap and annular member and thus prevents leakage even though the seal 1 may have been perforated or removed.

In the form of device shown in Figures III and IV the neck 2a of the bottle is substantially square so that it cannot be ti htly closed by a stopper. The exterior of the neck, in the form shown in Figures III and IV, is provided with teardrop-like projections 4a. Fitted over the mouth of the bottle is a member be having a depending skirt conforming to the shape of the bottle neck 2a, with inwardly extending teardrop-like projections 6a, which, when the member 5a is in place on the neck, are interdisposed among the projections 4a on the bottle neck. Between the inner surface of the member 5a and the adjacent outer surface of the neck 2a is a layer of cement, the strength of which relative to the strength of the member 5a preferably is such that if an attempt be made to force the member 5a off of the neck 2a, the member 5a. will be destroyed more easily than the cement bond can be broken.

The upper portion of the member 5a is in the form of a threaded annulus, across the opening of which extends an integral diaphragm or seal 1a molded of the same material and at the same time with the member 5a, the juncture between the seal or diaphragm la and the member 5a being preferably made very thin so that the seal or diaphragm can be easily cut or broken away from the member 50. by inserting the pointed end of a tool, such as a knife blade, corkscrew or ice pick, through the thin juncture at the edge of the seal or diaphragm.

Screwed upon the threaded upper portion of the member 5a is an internally threaded cap Mia provided with a liner or gasket i la toprevent leakage between the member 5a and the cap lea. As a precaution to prevent parts of the diaphragm M from falling into the contents of the bottle, the space beneath the diaphragm la, may be loosely filled with an easily removable wad, such as I3a, which may be inserted in the closure or laid over the bottle mouth before the closure is placed upon the bottle neck.

In the form of device shown in Figure V the neck 2b of the bottle is round and is provided with a helical bead 3b; an annular member 51), provided with a complementary helical groove 62), being screwed into place on the bottle neck; a layer of cement lying between the adjacent surfaces of the neck and the annular member and binding them together, the strength of the ocment preferably being such that the annular member cannot be unscrewed from or otherwise forced olf the neck without destruction. As an additional deterrent to removal, the direction of the helical bead 3b and groove 5b may be such as to form a left-hand thread.

Molded across the opening in the annular member 51) and lying somewhat below its upper end is an integral diaphragm or seal lb. A circular groove is molded into the seal or diaphragm adjacent its edge to provide an easily breakable juncture so that the diaphragm may be punched out with the finger or any instrument, such as a pencil or key, which is small enough to be pushed into the opening.

In the form of device shown in Figure VI the neck 2c is provided with a circumferential bead 30. An annular member 50 is provided with a bead 60, which, when the annular member 50 is mounted on the neck 20, lies adjacent the bead 30 on the neck. Molded across the opening of the annular member 50 is a diaphragm 1e, preferably of foil, or thin metal capable of being easily torn or perforated, or of parchment or the like. If desired, the diaphragm Ic may be partially cut through or scored along a line at which it is desired that the diaphragm shall tear most easily.

The annular member 50 extends upwardly sufficiently to form an adequate receptacle for a cork we or similar stopper. When the cork is removed an opening may be punched or torn in the diaphragm lc by pushing a finger or an instrument such as a corkscrew or pencil through it. A gasket He is interposed between the top of the bottle neck and an internal shoulder on the annular member 50 to prevent leakage between the bottle neck and the member. A metal band He is spun over the beads 30 and 60 to hold the memfaces of the neck 2d and the member 5dand filling the grooves 3d and 5d. In this form of the device the annular member Ed has an integral diaphragm 'ld molded across its opening adjacent its lower end, the diaphragm having a circular groove molded therein adjacent its edge to provide an easily breakable juncture. The upper portion of the member 5d is shaped to receive a cork or other stopper (not shown).

In this form of the device, means is provided to break the diaphragm around the thin line formed by the circular groove and remove it through the stopper opening. This diaphragm breaking and removing means consists of a disk Hid and a line i511 which may be of cord or wire and which extends through small perforations in the diaphragm Id and the disk Kid. The disk ltd and the line ltd are preferably assembled with the annular member 5121, after it is molded, but before it is placed upon the bottle neck 2d. The line lfid is dropped or folded upon the upper face of the diaphragm Id and lies beneath such cork or stopper as is placed in the opening above it. After the cork or stopper has been removed, the line may be spilled from the opening by turning the bottle upside down so that it may be grasped, and after the bottle has again been righted' the diaphragm may be pulled out by means of the line. 7 Figures VIII, IX and X show a'flask or bottle the" neck 2e of which is provided with inwardly projecting protuberances 36 to prevent the mouth from being tightly fitted with a stopper or cork in case an attempt is made to use the bottle without my fitting.- The exterior of the neck is provided with circumferential beads 4e. I

Fitted over the mouth of the bottle is an annular member 5e provided with grooves lie to receivethe beads ie on the bottle neck. Before the annular member is pushed into place on the upper end of the neck 26 a coating of cement is applied to one or both of the surfaces of the neck and annular member to be engaged, the character of the cement preferably being such that when it has set or hardenedthe annular member Becaunot be removed from the neck without destroying either the annular member or breaking the bottle neck.

At the upper end of the annular member 5e and closingthe opening therethrough is an integral diaphragm or seal Te molded of the same materialand at the same time withthe member 56, the juncture between the seal or diaphragm 1e and the member 5e being r'eferably made very thin so that the seal or diap ragm can be easily cut or broken away from the member 56 by inserting the pointed end of a tool, such as a knife blade, corkscrew or ice pick, through the thin juncture at the edge of the seal or diaphragm.

The upper portion of the annular member 5e is interiorly threaded, and screwed into such interiorly threaded upperportion of the member 5e is an externally threaded stopper lfle, which may be made of syntheticresin, metal or other material the dimensions of the lower portion or skirt of the member 5e which surrounds the bottle neck being such that the threaded stopper Ifle can be screwed into place through the lower end of the annular member 5e before the fitting is placed upon the bottle neck. The stopper llle is provided in its lower side with a screwdriver slot to facilitate screwing it into place.

In assembling the device the stopper llle is screwed into the fitting from the bottom, cement is applied to the exterior surface of the bottle neck and the interior surface of the fitting which are to be cemented together, a liner or gasket I la is laid on the top of the bottle neck and the fitting is pushed down into place on the neck. When it is desired to remove the contents of the bottle, the diaphragm la is broken away from the top of the fitting 5e. The stopper llle may then be removed through the top of the fitting as indicated in Figure X.

In the form of device shown in Figure XI the neck 21 of the bottle is preferably of non-circular form so that it cannot be tightly closed by a stopper. The exterior of the neck of the bottle is provided with teardrop-like projections 4f.

. Fitted over the mouth of the bottle is a member 5f having a depending skirt conforming to the shape of the bottle, with inwardly extending teardroplike projections 6 which, when the member 5 is in place on the neck, are interdisposed among the projections M on the neck. Between the inner surface of the member 5 and the adjacent outer surface of the neck 2 is a layer of cement, the strength of which relative to the strength of the member 5 preferably is such that if an attempt be made to force the member 5 off of the neck '21, the member 5 will be destroyed more readily-than the cement bond can be broken.

The upper portion of the member 5! is inthe form of an internally threaded annulus, across the opening of which extends an integral seal 1 molded of the same material and at the same time with the member 5f, the juncture between the seal '51 and the member 5 being preferably made very thin so that the seal can be easily broken away from the member 51.

Fitted within the threaded upper portion of the member W is an externally threaded stopper Iflf which has a finger-piece projecting upwardly through the seal if. The stopper Hlj, which is preferably made of metal but which can be made of other material, is molded in place in the fitting 5f when the fitting is made, the stopper being placed in the mold withthe moldable resin or other moldable material of winch the fitting 5f is formed. When it is desired to remove the stopper lflf the seal If may be broken away either with a pointed instrument such as a knife or ice pick or by forcibly turning the stopper Hi). A gasket or liner Hf between the stopper l6 and the top of the bottle neck serves to prevent leakage around the stopper l when it is replaced after having once been removed.

In the form of device shown in Figure XII the neck 2g is round and is provided with a helical bead 3g, an annular. member 59, provided with a complementary helical groove 69, being screwed. into place on the bottle neck, a layer of cement lying between the adjacent surfaces of the neck and the annular member and binding them together, the strength of the cement preferably'being such that the annular member cannot be unscrewed from or otherwise forced off the neck without destruction. As an additional deterrent to removal, the direction of the helical bead 3g and groove 6g may be such as to form a left-hand thread.

At the upper end of the annular member g and closingthe opening therethrough is a seal 1g, preferably of foil, or thin sheet metal capable of being easily cut or torn, or of parchment or the like. The seal lg is provided with a downwardly extending flange 8g which is molded into the material of the annular member 59. The seal may be scored adjacent its periphery so that it can be easily torn away.

The upper portion of the member 5g is internally threaded and screwed into such internally threaded portion from the bottom is a threaded stopper mg, which, when the seal lg is removed, can be unscrewed through the top of the annular member 5g when it is desired to obtain access to the contents of the bottle and which can again be screwed into place when it is desired to again close the bottle. A gasket or liner I lg overlies the top of the bottle neck and is adapted to be compressed between the bottom of the stopper lflg and the top of the bottle neck to prevent leakage around the stopper. I
