Description:

The present invention relates to sealed packages and the parts thereof, and more particularly, to a tamper proof seal.

Manufacturers of products which are packed in sealed containers are particularly interested in having the ultimate consumer purchase their products in the same condition as they leave mhe factory. In many instances, dishonest dealers impose upon the manufacturer, and upon the public, by adulterating the contents of the package or by removing the contents and refilling the packages with an inferior product. In either case, they are sold as original and genuine packages, but the consumer does not receive the beneflt of the goods for which he is paying. Naturally, such frauds create dissatisfaction on the part of the consumer and are detrimental to the good will and reputation of the manufacturer.

In an effort to guard against the above contingencies, packers have, in some cases, adopted impractical closures which must be destroyed or substantially deformed when they are removed.

In many instances, it is desirable to use the closure again to protect the remaining contents of the package and, hence, destruction of the closure is objectionable. . Another method resorted to by manufacturers consists in placing a label across the cap and the container to prevent removal of the cap without destruction of the label. Such labels can easily be counterfeited, and the original label can be readily steamed off and replaced without detection. Attempts have also been made to close the interior of nozzles. The latter is objectionable because the internal closure is concealed, it is difficult to open, and portions of the metal forming the closure are likely to fall into the contents of the can.

The present invention aims to provide a tamper proof-package, comprising a closure securely locked upon a container, which can be removed only by destroying a part thereof which can be readily accomplished. The invention also aims to provide a closure which can be replaced to form an effective seal which discloses the fact that the original seal has been broken.

An object of the present invention is to provide an inexpensive tamper proof seal for a container.

Another object of the invention is to provide a closure which cannot be removed without destruction of a part thereof.

Another object of the invention is to provide a tamper proof closure which forms an effective reseal to protect the remaining contents of the package during consumption thereof.

5 Another object of the invention is to provide a tamper proof band for a closure cap which may be securely locked upon the cap and which may be removed readily by destruction thereof.

A further object-of the invention is to provide a protective band which bears the trade-mark of the manufacturer or otherwise identifies the genuineness of the product.

Other and further objects of the invention will be obvious uponi an understanding of the illustrated embodiment about to be described or will 3 be indicated in the. appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

A preferred embodiment of the invention has U been chosen for purposes of illustration and description and is shown in the accompanying drawing, wherein Fig. 1 is a side elevational view illustrating a preferred embodiment of the present invention; Fig. 2 is a sectional view taken along the line 2-2 of Fig. 1 showing the closure locked upon the container; Fig. 3 is an exploded perspective view illustrating the parts of the closure removed from the container.

Fig. 4 is an enlarged fragmentary perspective view illustrating the manner in which the band may be removed; Fig. 5 is a fragmentary perspective view illustrating a modified band construction; Fig. 6 is a fragmentary perspective view illustrating another modification of the present invention; Fig. 7 is a fragmentary perspective view illustrating still another modification of the present invention; and Fig. 8 is a sectional plan view illustrating a slightly different band secured about a cap.

Referring again to the drawing, and more particularly, to Figs. 1, 2 and 3, there is shown a nozzle or outlet I adapted to be attached to a metal container 2 or the like. The nozzle preferably comprises a cylindrical body part 3 having an upper part which is flanged outwardly and rounded to form a crown or sealing surface 4. The flanged part of the nozzle is also bent downwardly, and flared outwardly to form a shoulder 5 with a downwardly extending cylindrical part 6 substantially larger in size than the crown part 4. Preferably, the lower edge of the cylindrical part or skirt 6 is cut to provide suitable inclined portions 7 merging into horizontal portions 9 which have at their ends, stops or vertical projections 10. The inclined portions 7 cooperate with suitable lugs or projections on a closure cap, as described hereinafter, to pull the cap downwardly and to form a secure seal. The horizontal portions i provide means for holding the cap on the' nozzle without creating any tendency for the cap to become loose or to be accidentally removed therefrom. The stops 10 limit the relative position of the lugs of the cap with respect to the threads to prevent the cap from being turned too far upon the nozzle.

Suitable recesses II are provided in the shoulder 5 between adjacent threads to permit the lugs of the cap to pass therethrough and engage the lower edge of the thread portions 7 and 9. In addition, the recesses I I are utilized to lock the cap oif the nozzle. This function will be described in detail hereinafter.

A preferred type of cap 12 is illustrated herein with a cover portion 14 and a depending skirt 15 formed integral therewith. The lower edge of the skirt is rolled into a bead 16 to strengthen the skirt and is provided with suitable lugs or projections 17 extending radially inwardly for engaging the thread portions 7 and 9 of the nozzle. Preferably, the skirt of the cap is knurled or corrugated as shown at 19 to facilitate gripping of the cap. A suitable liner 20 is preferably placed in the cap to provide a seal upon the crown part 4 of the nozzle.

In order to carry out the primary objects of the present invention, that is, to lock the cap upon the container, the skirt 15 is provided with an aperture or a plurality of apertures 21. Preferably, as many apertures are provided as there are lugs and these are definitely spaced about the circumference of the skirt with respect to the lugs 17 so that upon application of the cap to the container, and engagements of the cap lugs with the stops 10 on thenozzle, the apertures 21 register with the recesses II provided between adjacent threads.

Various devices may be utilized to interlock the closure cap and the recesses II. A preferred form of device is shown in Figs. 1, 2 and 3 and may comprise a tamper proof band 22 made from a strip of sheet metal or the like, with suitable projections 24 formed therein to register with the apertures 21 in the skirt of the cap. As illustrated, the projections 24 may be formed by punching or drawing a portion of the strip into the shape of a substantially cylindrical extension sufficiently small to fit into the apertures 21 and sufficiently strong to lock the cap in position by engagement with the sides of the recesses 1 1.

One end of the band 22 is. provided with a suitable eyelet 25 adapted to be inserted through an aperture 26 at the other end of the band, and thereafter compressed, as shown in Fig. 2, to lock the ends of the band together. The ends of the band may also be fastened in any other suitable manner to achieve the desired objects.

When the band is thus assembled about the cap, the projections 24 extend through apertures 21 and register with'the recesses II between adJacent threads of the container whereby removal or rotatibo of the cap is prevented without destructifliof the band. The projections 24 prevent accidental or intentional unscrewing of the 7 cap. They also prevent removal of the band without destruction thereof. The corrugations 27 serve a two-fold purpose, first, they permit the band to be stretched during application thereof to accommodate slight variations in size, and d secondy, they cooperate with the corrugations 19 in the skirt of the cap to hold the band thereon However, excellent results may be obtained without the corrugations.

If desired, suitable notches 29 or weakened portions substantially adjacent to the connected ends of the band may be provided.

A suitable member 30 (Fig. 4) may be inserted through the aperture '25 and thereafter, twisted to disconnect the ends of the band. Hence, the notches are not essential but are sometimes desirable. Since the bands have to be fastened by special machinery or tools, dishonest persons cannot readily tamper with the seal or the contents.

Where the notches 29 are used, the band usually breaks at the notches and cannot be replaced.

In Fig. 5 a slightly modified form of band is shown wherein a block 31 of suitable material is welded or otherwise secured to the band 22.

The block 31 is adapted to project through the aperture 21 of the cap and register with the recess II in substantially the same manner as the projection 24 of the preferred embodiment. An advantage of this construction is that the appearance of the package is enhanced since the lock- 26 ing projections are not visible.

In Fig. 6 a portion of a tamper proof band is shown having a substantially oblong or' rectangular projection 32 formed therein. In this construction the side flanges 34 of the projections engage the respective head and tail ends of adjacent threads while the upper flange 35 extends beneath the lip or flange Biof the nozzle to hold the band securely upon the container, and at the same time, lock the cap against rotation or re-35 moval.

In Fig. 7 another modification is shown wherein, a tab 36 is provided by slitting the metal of the band below and at the sides of the tab, and bending the tab 36 upwardly and inwardly so that it is adapted to project through the aper- 40 ture of the cap and registers with the recess I1.

A continuous band 37 Is shown in Fig. 8 telescoped about the skirt of a-closure cap as shown in the preferred embodiment. The projections 39 are preferably formed in the band during its 45 application by a suitable machine which presses portions 39 of the band into the apertures of the cap.

While several ways of utilizing the invention have been shown, it will be understood that these 50 are merely illustrative and that other means may also be utilized. It will be understood also, that the invention may be utilized with other types of containers, for example, glass containers.

By stamping cr cutting the bands from litho- 55 graphed sheet material of particular color or decoration, the manufacturer may improve the appearance of the package, identify the product, and feature the tamper proof seal.

The bands can be readily removed by inserting 60 a pointed member such as the prong of the fork into the eyelet or between the band and cap, and twisting the same either to break the band at the notches, or pry open the joined ends. In either instance, the inwardly projecting portions of the 65 band can be withdrawn from the recesses between the threads and can be removed from the apertures in the skirt of the cap to permit the cap to be unscrewed. It will be noted that the band is destroyed in this manner thus, insuring 70 the package against tampering or substitution of the contents, but at the same time, the cap is not distorted and is fully, capable of providing an effecive seal for use during consumption of the contents of the package. 75 It will be seen that the present invention provides a simple inexpensive closure which is tamper proof and provides a sealed package which cannot be imitated or counterfeited. The parts of 8 the closure can be readily manufactured by existing machines without substantial increase in cost of material. Likewise, automatic machines may be utilized for applying the closures upon containers. The package provided herein is attractive in appearance, is provided with a secure seal, and the parts thereof, are rugged in construction and fully capable of withstanding any rough usage to which they may be subjected.

As various changes may he made in the form, construction and arrangement of parts without departing from the spirit and scope of the invention and without sacrificing its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
