CONTAINER LID WITH IMPROVED PILFER PROOF SEAL

Abstract

The invention relates to the pilfer proof seal for the container lid comprising integrally molded seal 204 in the lid having thin section 205 all over the periphery of the seal 204, which can be cut open for making the spout 206 accessible, yet another seal 209 being provided at the spout end at least 20 to 30 millimeter inside from the mouth of spout 206, being provided with a thin section 210 at its periphery which should be cut by pulling the ring 211 one end of which is affixed to the seal 209 near the periphery of the seal 209, the spout 206 being pulled out by handle 207 fixed to the threaded cap 208 in hinged manner in known way, the seal 204 not being reparable due to large area to be cut and seal 209 not easily reparable due to large area and also not being easily accessible for repairs making the assembly pilfer proof.

FORM 2 THE PATENTS ACT, 1970 (39 of 1970) COMPLETE SPECIFICATION [See section 10] CONTAINER LID WITH IMPROVED PILFER PROOF SEAL; L. G. SYSTEMS A REGISTERED PARTNERSHIP FIRM WHOSE ADDRESS IS 12, HINDUSTAN KOHINOOR INDUSTRIAL COMPLEX, LBS. MARG, VIKHROLI (WEST), MUMBAI - 400 083, MAHARASHTRA, INDIA. THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES AND ASCERTAINS THE NATURE OF THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFOMED. TITLE OF INVENTION Container lid with improved pilfer proof seal. FIELD OF INVENTION Pilfer proofing of liquid carrying containers. PRIOR ART Plastic containers are commonly used in storage and transportation of the liquid products. To make pouring easy the containers are provided spouts which can be pulled out for pouring and pushed back in the lid after pouring operation is over. While the liquid filled container is in transit or in storage it is prone to being pilfered and hence various measures are taken to make it pilfer proof. Particularly for the above mentioned types of pull out spouts the method used for pilfer proofing is to provide a seal which if found broken indicates pilfering. The commonly used method of sealing such containers is described below with help of figures 1 to 4. Fig.1 - The sectional elevation of the lid as fitted to the container as according to prior art. Fig.2 :- The enlarged top view from A shown in figure 1 of the lid on pilfer proof seal according to the prior art. Fig.3:- Enlarged sectional view showing section A-A with reference to Fig 2 according to prior art. Fig 4:- Enlarged sectional view as above with seal broken and spout projected out from the lid, according to the prior art. Fig 1 to Fig 4 show prior art, with reference to these figures 101 is the container and 102 is lid of the container 103 is the pilfer proof spout assembly according to prior art. The seal for pilfer proofing 104 is secured in a notch 105 in the metal ring 106 crimped on the projection 107 built in the lid. 108 is a spout for pouring liquid from the container 101, which can be pulled out by means of handle 111 which is provided on a threaded cap 111 fitted on the outer end of the spout 108. Another seal 110 is provided at the end of the spout as shown. The whole assembly is claimed to become pilfer proof due to seal 104 and the seal 110. however these seals have following shortfalls. The seal 104 i.e. the outermost seal of the assembly is not firmly secured. Due to this the complete seal comes out with a tool like screw driver or similar tool and can be refitted again. This seal 104 is made of flexible material and hence the function of pilfer proofing is not achieved by seal 104. Secondly this whole assembly is crimped by a metal ring 106. This whole assembly comes out very easily with a screw driver and can be refitted. In most cases the consumer will not come to know the defect in the sealing. Also this complete assembly is independently sold in the market and hence, the spout assembly ca be easily replaced by a new one without showing the sign of pilferage. Thus the object of pilfer proofing in this arrangements can be very easily defeated. The present invention overcomes this deficiency, by making use of outer seal with large sealing area and providing the inner seal, which is not easy to access for repair after pilfering operation. DESCRIPTION OF THE INVENTION Fig 5 to Fig 8 show pilfer proof seal as per the present invention. Fig 5:- The sectional elevation of the lid as fitted to container according to the present invention. Fig 6;- The enlarged top view from B shown in Fig 5 of the lid with pilfer proof seal according to the present invention. Fig 7:-Enlarged sectional view showing section B-B with reference to fig 6 Fig 8:- Enlarged sectional view as above with seal broken and spout projected out from the lid according to present invention. Container 201 is closed by a lid 202 on top of it. The pilfer proof seal assembly with spout is shown as 203 Outer seal 204 is molded integral with lid 202. The thin section 205 all over the periferry of this seal 204 is to be cut for opening this seal. It can be seen that once this thin section 205 is cut open it can not be easily repaired without showing its obvious damage to hide the pilfering operation, due to large area which should be sealed after cutting. Fig 8 shows 204 as the seal totally detached from lid after cutting. The spout 206, which can be pulled out by handle 207, provided on threaded cap 208 at the spout outer end in known way in the hinged manner. However the seal 209 at the end of the spout 206 is provided at substantial distance from the mouth of the spout 206. It is at least 20 to 30 millimeters inside from the outer end of the spout. This seal 209 is provided and thin section 210 at its periferry which is to be cut before the containts of the container can be poured out. As the seal 209 is not easily accessible for opening from spout end, an opening ring 211 is affixed to this seal 219 which is a strong circular ring of which one end is affixed to the seal 209 by integral molding or plastic welding or the like. When the ring 211 is held firmly between fingers and pulled the thin section 210 around the periphery of seal 209 is teared off so that the mouth of the spout 206 is opened for pouring out the containts of the container. Being at least 20 to 30 millimeters inside from the mouth of the spout this seal once broken can not be repaired to conceal the pilfering operation. Thus with these arrangements the container becomes positively pilfer proof. WE CLAIM: 1. A pilfer-proof seal for a container, comprising: a lid (202) to close the container; a spout (206) having a threaded cap (208), said spout being pulled out of the lid (202); and -at least two molded seals (204, 209) with a thin section (205, 210) provided all over the periphery of each seal; characterized in that said spout (206) is connected to the lid (202) inside the container (201); and that one (204) of the seals is integrally provided on the lid (202) to allow access of the spout (206) and another seal (209) is provided with a pulling ring (211) inside the spout (206) substantially below from the mouth of the spout (206) such as 20-30 millimeter from the mouth of the spout; wherein the seal (204) provided on the lid (202) being not reparable due to large area of cut and the another seal (209) not repairable being provided inside the spout (206) and also the spout assembly not replaceable being connected inside the container seal the container (201) pilfer-proof.
