3 Claim.
has been no subst'tutes or adulteration. More particularly the invention relates to a container closure means of the type disclosed in the application of Benjamin F. Conner, Serial No. 723,864 filed May 4, 1934, and in the application of Benjamin F. Conner and William F. Schmalz, Serial No. 723,865 filed May 4, 1934.
In accordance with the present invention there is provided a readily breakable indicator member which is structurally separate from the main closure for the container and which is adapted to be put in place on the container after the closure is in place. The indicator member is so shaped that it cannot be substantially turned independently of the closure, and the indicator member and the container are provided with interengaging means which serve to break the indicator member when the closure and the said member are turned to unscrew the former. Preferably the indicator member is in the form of a ring. which surrounds the lower portion of the closure and leaves the top thereof exposed.
In the accompanying drawing I have shown the embodiment of the invention which I now deem preferable, but it will be understood that the drawing is intended for illustrative purposes only and is not to be construed as limiting or defining the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.
Of the drawing: M r
Fig. 1 is a vertical sectional view of a container closure means embodying the invention, the
closure means being in place on a bottle which is shown inelevation.
Fig. 2 is a plan view of the container closure means shown in Fig. l, the bottle beingomltted. Fig. 3 is a perspective view of the metallic means for engaging the indicator member to hold it in place. i
Fig. 4 is a. horizontal sectional view taken along the line 4-4 of Fig. 1. I
Fig. 5 is a view similar to Fig. l, but showing the closure and the indicator member relatively turned so as to break the skirt portion of the latter.
Referring to the tainer with which embodying the invention container having a mouth container is shown will be understood that with a wide variety drawing, l represents a conthe container closure means may be-used, the said or opening 2. The being a glass bottle, but it the invention may be used of containers. As shown the external thread 3 and with an annular bead 4 below the thread. For closing the mouth of the bottle there is provided a closure cap 5 which may be of standard form. The cap 5 has an internal thread 6 which engages the external thread on the bottle and the cap is provided with a gasket or liner 1 in accordance with usual practice. The cap 5 is noncircular in horizontal section and 'as shown it is hexagonal.
Associated with the cap 5 is an indicator member 8 which is of such size and shape that it can be put in place on the container after the closure cap 5 is in place.
the indicator member surrounds the lower While I do not limit myself, 8 is preferably a ring which leaves the upper portion entirely exposed. The
indicator member, or engage with the closure cap in ring 8 is shaped to intersuch a manner as to prevent relative rotation. As shown, the inner opening in the ring is .mately fit the exterior hexagonal to approxishape of the cap.
Associated with the indicator ring and with the closure cap is a me ans which permits downward movement of the indicator ring into normal relationship with the prevents upward movement thereof out of such relationship. Preferably and as shown the ring 8 is provided with a shallow interior annular groove 9 which is adapted to receive a metallic strip l0 as shown bounded at the bead II which is of the ring tobe stripped from the it is formed. The conform to the into in Fig. 3. The groove B'is bottomby an inward projecting small size that it permits mold on which metallic strip Ill-is shaped to rior contour of the ring 8 and such to fit the groove 9 thereof, and it is snapped into place in the groove ring 8 with the cap in is provided prongs I2, l2.
The ring 8 is. pr
l tending annular skirt 9 prior to the assembly of the and the container. The strip with inward projecting resilient ovided with a downward ex- 13 which is readily breakable. To facilitate breaking, the skirt may be made very thin, ening notches as in or it may beprovided with weakdicated at l4, H. To further but which automatically facilitate breaking of the skirt, an annular groove is provided at I5 to provide a zone of weakness between the skirt I3 and the main body of the ring 8. Formed integrally with the skirt I3 is at least one inward projecting cam I6 and preferably there are two such cams arranged oppositely. The bead 4 on the bottle is provided with cams I I, I1 adapted to cooperate with the cams I6, I6.
In using the closure means the container is filled in any usual or preferred manner and the primary closure cap is put in place in accordance with usual practice. The metallic strip I0 is first assembled with the ring 8, as already described, and then the ring 8 is fitted over the closure cap and pushed downward into its normal position as shown in Fig. 1. In this positionthe prongs I2, I2 on the metallic strip In spring inward and are in position to engage the bottom of the cap 5 .to prevent upward removal of the ring 8. With the ring 8 in its normal position as shown, the skirt I3 thereof surrounds the head 4 on the bottle and the cams IT, I I on the bottle are in the paths of rotary movement of the cams I6, I6 on the skirt I3. It will be observed that in assembly care must be taken to put the ring 8 in place with the cams I 6, I 6 out of engagement with the cams I1, I1.
In order to open the container it is merely necessary to rotate the closure cap 5 in the ordinary manner. The indicator ring 8 necessarily rotates with the cap, and this rotation of the ring brings the cams I6, I6 into engagement with the cams IT, IT, thus causing the breaking of the skirt I3 as indicated in Fig. 5. With the skirt I3 broken as shown, the cap 5 and the remainder of ,the indicator member can be readily removed.
It will be observed that the indicator is necessarily broken when the closure cap is unscrewed, thus providing a definite indication that there has been at least an attempt to obtain access to the contents of the container. With the indicator memberbroken, the customer, or in fact anyone else handling the package, will know, or at least have reason to suspect, that the contents of the container have been tampered with and he should refuse to accept the package. Thus by refusing to accept any package on which the indicator member is not intact the customer can protect himself against adulteration or substitution of the container contents. It will, of course, be understood that the indicator member will ordinarily carry a suitable trade-mark to provide additional protection to the customer.
While I do not so limit myself I prefer that the indicator member 8 be molded from a material of the synthetic resin class. Such a material is somewhat brittle and is readily broken when provided with sufiiciently thin walls or with suitable zones of weakness, as for instance those at I4, I4 and I5. Such a material has the further advantages that it is available in a variety of colors and can be readily molded to provide any desired external trade-mark or ornamental design.
What I claim is:
l. The combination in a container closure means, of an internally threaded closure adapted to engage an external thread on a container and to close the container opening, a preformed readily breakable indicator member structurally sepa rate from the closure and adapted to be put in place on the container after the closure is in place, the said member being shaped to interengage with the closure to prevent substantial relative rotation, a normally concealed means permitting downward movement of the indicator member into normal relationship with the closure but automatically preventing upward movement out of such relationship, and means on the indicator member adapted to engage with the container and thereby break the said member when the closure and member are turned to unscrew the former.
2. The combination in a container closure means, of an internally threaded closure adapted to engage an external thread on a container and to close the container opening, a preformed readily breakable indicator ring adapted to be put in place on the container after the closure is in place so as to leave the upper part of the closure exposed, the said .ring being shaped engage with the closure to prevent substantial relative rotation, a normally concealed means permitting downward movement of the indicator ring into normal relationship 'with the closure but automatically preventing upward movement out of such relationship, and means on the indicator ring adapted to engage with the container and thereby break the said ring when the closure and ring are turned to unscrew the former.
3. The combination of a container having an external thread and having an annular bead below the thread, a closure having an internal thread engaging the external thread on the container, an indicator ring positioned to leave the upper part of the closure exposed and having a depending readily breakable skirt covering the head on the container, the said ring being adapted to be put in place on the container after the closure is in place and being'shaped to interengage with the closure to prevent substantial relative rotation, a normally concealed means permitting downward movement of the indicator ring into normal relationship with the closure but automatically preventing upward movement out of such relationship, and means on the skirt of the indicator ring and on the container adapted to to interinterengage and thereby break the said skirt when Y the closure and ring are turned to unscrew the former.
