19 Claims.

This invention relates to closures for containers.

It has been found that with ordinary closures, purchasers of various products, particularly liquors, cannot be sure that they are getting the legitimate product for the reason that the contents of the bottle or other container are often tampered with between the packaging source and the consumer. Various ways of preventing this illicit tampering have been attempted but, for one reason or another, they have not proved entirely satisfactory.

It is an object of the present invention to provide simple and effective means for closing bottles and other containers such that the contents cannot be tampered with, at least without the fact of such tampering being made evident.

It is a further object of the invention to provide closure means for containers such that the container is initially hermetically sealed, such seal being readily and quickly broken when it is desired to use the contents.

It is a still further object of the invention to provide a closure for containers having improved means for sealing a once opened container against leakage.

With these and other objects in View, the invention consists in the features, combinations, details of construction and arrangements of parts which will first be described in connection with the accompanying drawings and then more particularly pointed out.

In the drawings:

Fig. 10 is a perspective view of another part;

Fig. 11 is a sectional view showing the cap of Fig. '7 on a different section line; and

Fig. 12 is a sectional view of a further modification.

Referring to the drawings, and more particularly to Figs. 1-6, there is provided a container and an initially imperforate end closure for initially completely closing and sealing the mouth of the container, this end closure having a frangible portion which is subsequently punctured to permit discharge of the container contents.

As here shown as an example, a container, such as a bottle 2 i, has a neck 22 provided with a thread 23. At the mouth of the bottle is the usual locking ring 24, such as is commonly provided for securing crown corks and other well known closures.

While the initial end closure and its frangible portion may vary in construction and arrangement, in the present 'exemplification it is part of an attachment which also performs other functions hereinafter referred to. To this end, the attachment comprises a ring-like body portion 25 surrounding the mouth of the bottle. Extending inwardly from body portion 25 is a clamping flange ZS-overlapping the lip of the bottle. To prevent leakage between the bottle and the attachment a gasket 2? of cork or other suitable material may be interposed between flange 23 and the bottle lip. From the flange 26, the wall of the attachment has an upstanding portion 28. Inside the latter is a relatively hori zontal frangible annulus 29 and inside that is a conical plug or valve element 30 hereinafter referred to. Below body portion 25 is an inwardly extending bend 3| which takes under the shoulder of the bottle locking ring 2t. It will now be apparent that this bend and the clamping flange 25 serve to secure the attachment to the bottle. In the present exemplification, the bend 3| is formed by spinning the metal of the attachment in under the locking ring shoulder.

In carrying out the invention to what is now considered the best advantage, the frangible portion of the initial end closure is arranged to be disrupted over a predetermined area. This may be accomplished, for example, by weakening the wall of the end closure in such a manner that a given area of metal is broken away. In the exemplification illustrated in Figs. 1-6 the attachment which comprises the end closure is formed of so-called sheet metal and the weakening is conveniently accomplished by scoring the annulus 29 to define the area or areas to be broken away.

\ To this end, and as shown more clearly in Figs.

1 and 5, the annulus 29 has four weakened portions. Each area 33 to be broken away is defined by an end scoring 34 and two

side scorings

35, 36. There is no scoring at the remaining end in order that the metal will be disrupted in the form of tongues which remain rooted to the annulus, whereby no metal is allowed to drop into the container.

The invention in its entirety includes a cap for the container, axially movable on the container neck, and means for causing the frangible portion of the end closure to be broken away upon the initial movement of the cap into full closed posi tion. Although capable of various constructions,

in that illustrated as an example in Figs. 1-6,

a cup-shaped cap 31 telescopes the bottle mouth and has an internal thread 38 engaging the bottle thread 23. This cap may conveniently be formed of molded plastic material. Extending downwardly from the top of the cap are one or more puncturing elements or breakers 39, the. number depending upon the number of areas in the end closure that are to be broken away. In the present instance there are four such areas and four breakers.

With reference to the direction of rotation of the cap in approaching closed position, the leading face of each breaker 39 is slightly rounded and is V-shaped at the bottom to provide a piercing or breaking point. As appears more clearly in Fig. 6, each breaker recedes, toward the trailing end, to a vanishing point, to enable the cap to be removed from the manufacturing mold.

The invention in its entirety includes means for initially assembling the attachment in a predetermined angular position and for subsequently preventing relative angular movement of the attachment, thereby to insure the breakers and the weakened areas of the diaphragm having the proper relative position. While this may be accomplished in various ways, in the embodiment here shown as an example, the locking ring 24 has a vertical groove 42 and the body portion 25 of the attachment has a struck-in nib 43 which takes into the groove 42 (Fig. 4). I

With this construction, the attachment may be initially assembled in a predetermined angular position on the bottle mouth and is thereafter locked in such position. In this way, the breakers are properly positioned with respect to the weakened areas. In the present embodiment, as will be more apparent hereinafter, it is desired that the puncturing operation end with the cap in full closed position. Consequently, the attachment is given such a position that when the cap is sufficiently short of full closed position to enable the puncturing operation to be completed during final movement, the advance points of the breakers are just about to engage the end scorings of the weakened areas.

After the bottle has been filled and the initial end closure attached, the cap is assembled but is screwed down only part way toward full closed existence of this unbroken end closure prevents tampering with the contents.

When it is desired to use the contents, the cap is screwed down to full closed position. During this combined rotary and axial movement of the cap, the leading ends of the puncturing elements 39 are forced against weakenedareas 33- and cause the same to be broken away along the scored lines. The displaced metal rolls or curls up ahead of the breakers in the form of tongues which remain rooted integrally to the annulus 29 (Fig. 2). This piercing or breaking away results in the formation of a plurality of ports or passages 44 through which the bottle contents may thereafter flow (Fig. 3).

The invention in its entirety includes a cap having a discharge port and a valve element carried by the container neck for closing said port in one position of the cap. As here shown as an example, centrally located in the top of the cap 31 is a conical discharge port or passage 45 (Fig. 3). When the cap is screwed down to closed position this port is ciosed and sealed by the conical valve element or plug 35 above referred to (Fig. 2).

The invention in its entirety includes means for indicating to a purchaser or user whether or not the cap has been given the predetermined movement necessary to puncture the initial end closure. This may conveniently be accomplished by means operable upon said predetermined movement for altering the external appearance of the cap. Although capable of Various constructions, in the embodiment illustrated as an example in Figs. 1 5, the cap discharge port 45 is initially closed by an integral web 46 which may conveniently be the molders flash. This web, at the top, is flush with the top of the cap so as to present a neat appearance. In order to insure an easy break-out of the web, its wall is made as thin as practicable around the edge thereof, as appears at 41 (Fig. 1).

In this particular embodiment the valve element or plug 30 is utilized to break out the web. As previously described, the initial end closure is punctured when the cap is first screwed down to closed position. It has also been stated that in closed position of the cap, discharge port 45 is closed by plug 30. It will be apparent, therefore, that the predetermined movement of the cap' that causes the end closure to be punctured also causes the web 46 to be broken out, thus altering the external appearance of the cap and indicating that the puncturing movement has taken place. Fig. 2 illustrates the parts at the end of this initial closing movement of the cap with web 45 just broken out. With the construction described, the web breaks out with a clean out leaving a. completed discharge port. It will be understood that the web drops away and is discarded. I

The invention in its entirety includes means for preventing complete removal of the cap and such means will advantageously be inaccessible. Although capable of various constructions, the locking means here shown as an example comprises a downwardly and outwardly extending locking flange 50.

part of the attachment previously described. As appears in the drawings (Figs. 1-5), the attachment has a V-shaped bend taking under the shoulder of the bottle locking ring 24, the lower leg of the V constituting the locking flange 50. Cooperating with this flange is a bead 5| formed on the inner wall of the cap, above the thread, and in a position to be below flange 50 when the This flange is of flexible and resilient material, e. g. metal, and is formed as cap is assembled on the container. This bead provides an upwardly facing shoulder the inner diameter of which is slightly less than the normal diameter of the rim of flange 50. Above head is a recess 52 to accommodate the flange 59 during opening and closing movements of the cap.

In the initial assembly of the cap onto the bottle neck, the thread crests and the bead 5| ratchet over the edge of flange 50 which yields or flexes inwardly. Once the bead 5| has passed, the flange springs back to approximately its initial position. Thereafter, it serves as a look-- ing abutment, cooperating with bead 5| to prevent removal of the cap. That is, upon a given upward movement of the cap, bead 5| engages the rim of flange 50, as appears in Fig. 3, whereby further movement is prevented. If desired, flange 5-9 may be split to facilitate its flexibility.

In carrying out the invention in its entirety, provision is made for sealing the container mouth in closed position of the cap, once the package has been opened, this sealing being designed to prevent leakage not only through the discharge port but also down through the thread. This may be accomplished, in connection with plug 30, by effecting a seal outside the ultimate passages in the initial end closure. Although capable of various constructions, in the exemplification of Figs. 1-6 the cap is provided with a shoulder 53. Secured to this shoulder in any suitable manner is a sealing gasket 54 of cork or other suitable material. When the cap is in closed position (Fig. 2), the discharge port 45 is closed and sealed by plug 30 and gasket 54 is compressed against clamping flange 26 to prevent leakage down the thread.

To review the operation: after the bottle is filled the attachment comprising the initial end closure is assembled on the bottle mouth, the proper angular position being determined by the engagement of nib 43 in groove 42 (Fig. 4). Then the skirt of the attachment is spun in under the bottle locking ring 24 and the end of the skirt is flared outwardly to form the locking flange 50. Finally, the cap 31 is assembled on the container, the bead 5| and thread crests ratcheting over the edge of flange 50. The cap and bottle threads are caused to inter-engage but the cap is screwed down only part way towards full closed position, being stopped before the breakers 39 engage the frangible portion of the end closure. The package remains in this condition until the user desires to discharge the contents.

With the construction described, the package is tamper-proof in the sense that no tampering is possible without the fact of such tampering being made evident. Since the same movement that breaks the initial end closure also breaks away web 46, the purchaser or user can tell at a glance whether or not the package is in its original condition. That is, if the top of the cap presents an unbroken surface, the purchaser knows that the contents are still sealed by the initial end closure and that there can have been no tampering. If, on the other hand, the cap has a port in its top face, the purchaser knows that the cap must have been so moved as to break the initial closure and he is thereby put on notice that there may have been tampering. With the construction described, moreover, the above mentioned indication cannot be avoided by removing the cap, puncturing or removing the initial closure, and replacing the cap with web 46 intact because the cap is locked against removal. And finally, since thelocking means is inaccessible, the lock cannot be tampered with without destroying the skirt of the cap and so making it evident that something is wrong.

When the user wishes to open the package, he screws the cap down to full closed position (Fig. 2), thus puncturing the initial closure and breaking out web 45 (Fig. 2). Then he screws the cap back to open position (Fig. 3), in which position the bottle contents can flow out through openings 44 and port 45. To re-seal the package, cap 37 is again screwed down to closed position. In that position, plug 30 closes port 45 and sealing gasket 54 prevents leakage down the thread.

In the construction shown in Figs. 1-6 a right hand thread for the cap is provided. It will be understood that for a left hand thread, the direction of facing of the breakers 39 and the weakened areas 33 will be reversed.

In Figs. 7-11 there is illustrated a modification. The main differences are that the attachment is in two parts instead of one and that there is a difierent method of subsequent sealing. In this additional embodiment, a container 55 has a neck provided with a thread 51 like the thread previously described. Telescoping the bottle neck is a cup-shaped, internally threaded cap 58 formed of molded plastic material. In the top of the cap is a conical discharge port 59 initially closed by an integral web 60 like the web previously described. In closed position of the cap the port 59 is closed by a conical valve element or plug 6|.

In packaging various liquids and other products it is considered necessary, or at least preferable, to avoid contact of the contents with aluminum, tin plate or other so-called sheet metals. The objections to such contact do not apply, however, to other materials such, for example, as pure tin (using the term to mean commercially pure tin, as distinguished from tin plate, but not necessarily chemically pure tin). To make the complete attachment, such as that shown in Figs. 1-6, of pure tin involves too great an expense and, in addition, pure tin is probably not suitable for the clamping and locking features of the attachment.

According to the present exemplification, there is provided a two-part attachment so constituted 1 that the part which comes into contact with the container contents may be formed of one material and the part which is secured to the container of another material. These parts may,

for convenience, be referred to as the closure part and the anchoring part.

As here shown as an example, the closure part (Fig. 9) comprises a ring-like body portion 65 and terminates at the bottom in an outward flange 65. Inside the body portion is a relatively flat frangible annulus 6'! and the plug 6|. This part of the two-part attachment, which comes in contact with the bottle contents, may be made of tin, e. g. what is known as extruded tin.

The anchoring part of the attachment, which does not come in contact with the bottle contents, may be made of any suitable sheet metal or the like. As shown (Fig. it comprises a ring-like body portion 68 at the top of which is an inward clamping flange 69 which overlaps the flange 65 to anchor the end closure when the parts are assembled. Below the body portion 68 is an inward V-shaped bend 10, the lower leg of the V constituting an outwardly and downwardly flaring locking flange ll.

ing ring'l3.

' 'tThe exemplification of a two-part attachment illustrated in Figs. 7-10 may be constructed to be assembled with a snap-on action. To this end, the v-shaped bend H3 and the. locking flange ll, which correspond to the ultimate bend and flange :of Figsxl -S, are pre-formed. The anchoring part .ofthe attachment is split, as at 12, at a number "of points around its circumference, these splits extending from the bottom edge'of the locking flange through the V-shaped bend and Well up into the body portion 68 (Fig. Cooperating with the split attachment, the bottle hasa lock- The lip of the bottle, which forms the top of the locking ring, is sloping or rounded,

as'appears in Figs. 7 and 8, for reasons hereinafter referred to.

To enable the anchoring part of the attach- -ment to be assembled in a predetermined angular position, the body portion 53 has an inward nib M which takes into a groove, like groove 42, in the locking ring of the bottle. This engagement also serves to prevent any relative angular movement after assembly. To enable the closure part of the attachment to be assembled and retained ina predetermined angular position, the clamping flange '69 has two notches which receive lugslt formed on the closure portion.

To assemble the two-part attachment above described, the two parts are first brought together into the relation of Figs. 7 and 8, the split V-shaped bend iii yielding to pass flange 66. Thereafter the attachment as a unit is assembled onto the bottle mouth. As the unit is applied to the bottle, the pressure of the V-shaped bend against the lip of the bottle causes the split skirt In this position, overlapped

flanges

66, 69, are

pulled down against the bottle'mouth, or against a sealing gasket i? if one is used, and the twopart attachment is secured, as a unit, to the bottle neck.

It is to be understood that the two-piece attachment may be secured in place by a spinning action instead of by the snap-on action just described. In that case, the anchoring portion is not pre-formed as to bend I6 and locking flange H and the splits 12 may be omitted. The two parts may be assembled together as above described, and then applied to the container as a unit, the skirt of the anchoring portion being spun in under the bottle locking rim and flared outwardly to form locking flange 'H. Similarly, the one-piece attachment of Figs. 1-5 may be adapted to a snap-on assembly by pre-forming and splitting the skirt.

The cap 53 has an internal bead 18, like the bead 5!, which provides an upwardly facing shoulder for engaging the locking flange H to prevent removal of the cap. The cap also has a recess 19 like recess 52. It will be apparent'that cap 58 is assembled in the same manner as cap 31.

In connection with Figs. 1-6, there was described the feature of effecting a seal, for a once opened container, outside the openings in the initial end closure. In the modification of Figs. 7-11 this scaling is accomplished by forcing or wedging a part carried by the container neck against a part of the cap when the cap is in full I w: ima ines l port .clos'ed'position. This further embodiment also has,:means for puncturing or breaking predeter- -mined areas of the initial end closure and the wedging. and breaking elements may conveniently be combined.

"In the exemplification illustrated in Figs. 7-9, V

annulus 6'5 is surrounded by an outer wall 8| which is conveniently a rim or lip formed as a continuation of ring 65. The annulus B1 is'provided with a plurality, in this instance four, weakened areas 83 formed conveniently by a thinning of the metal, as appears in Figs. '7 and 9.

Extending downwardly from the top of the cap and alined with annulus 61 is an annular wedge .84. At intervals corresponding to the number of weakened areas 83, this wedge is extended into a plurality of puncturing elements or breakers 85 generally like the breakers previously described. :Surrounding this wedge and spaced therefrom sufficiently to receive lip 8|, the cap has a vertical abutment wall 82.

ment, the breakers 85 puncture the weakened areas 83. While the drawings illustrate the metal as being broken away over the weakened areas. .and curled up ahead of the breakers, it' is to be understood that this does not necessarily result from'the construction described. It is possible that in some cases the weakened area will be split or ruptured and pushed aside.

puncturing provides passages in the end closure for the flow of the container contents. During .the'end' of this same movement of the cap, web :lii! is broken out by plug 6|. screwed up to open position again, thus opening Then the cap "is port 59 to permit discharge of the contents.

To reclose the container, the cap is again screwed down to full closed position. 'In this position plug 6| closes port 59 and the breakers entercand at least partially close the openings previously formed. The wedge 84 engages lip 8| and by its wedging action forces the lip outwardly against abutment wall 82 of the cap. This wedging action, by taking up the clearance between the cap and the attachment, due to manufacturing tolernaces, effects a tight seal around the entire periphery of the closure outside the end passages.

In Fig. 12 is illustrated a further modification.

In this embodiment certain features of the invention are shown in connection with a collapsible tube such as is used for pastes, creams and the like.

As shown as an example, a collapsible tube 88 has a threaded neck 89. Formed as an integral part of the neck is an initially imperforate end 'wall 95 having a plurality of weakened areas 9|,

in this instance three. These weakened areas are thinned portions of an annulus bounded by an outer wall 94 which is conveniently formed as a terminal lip on the container neck. Rising from.

In any event, the? this end wall and integral therewith is a conical plug or valve element 92.-

In threaded relation with the tube neck is a a cup-shaped cap I02 having a conical discharge No web for initially closing this port is illustrated'but'one may be used if desired. The cap has an annular wedge 95 extended at intervals to form breakers 96. Surrounding the wedge,

-and'spaced therefrom sufficiently to receive lip '94, is a vertical abutment wall 98. When the cap is first screwed down to full closed position the breakers break away the weakened areas 9|, as previously described in connection with Figs. 7-11, to form passages for the flow of the tube contents. After the cap has been opened and again closed, the breakers enter the passages to close the same and the wedge forces lip 94 against abutment wall 98, taking up the clearance, to efiect a seal. Carried by the tube neck is a locking flange like those previously described. To this end, as here shown as an example, a short distance below the mouth of the container is an external bead 99 which may be termed a locking ring since it is analogous, for this purpose, to the locking ring 13 of Figs. 7 and 8. Secured to this locking ring by a snap-on action is an attachment generally like the lower or anchoring part of the attachment shown in Figs. 7, 8 and 10 and terminating in looking flange I00. Cooperating with this flange, to prevent removal of the cap, is a bead Illl on the cap similar to the beads previously described. The cap has a gasket I04 corresponding to gasket 54 of Figs. 1-3.

In the exemplifications here shown and described, the locking flanges and complementary anchoring portions of theattachments are annular. It will be understood, however, that the invention is not limited to that form and that the desired result may be obtained by one or more segmental locking and anchoring elements.

In the various embodiments here illustrated, the caps and container threads are mutually engaged at all times, once the cap is assembled on the container. It is to be understood, however, that,

if desired, the parts may be so arranged that the cap thread disengages thecontainer thread before the internal bead of the cap engages the locking flange on the container. With such an arrangement the threads are not in engagement when the cap is in its uppermost or full open position and out of contact with the top of the initial closure element.

The invention has been described in connection with bottles and collapsible tubes but it is to be understood that the invention is applicable to various kinds and types of containers.
