FORM 2 THE PATENTS ACT,1970 (39 O F 1970) & THE PATENT RULES. 2003 COMPLETE SPECIFICATION [SECTION 10; RULE 13] "A CONTAINER HAVING LID WITH SPOUT" HITECH PLAST LTD., GUT NOS. 939 & 940. NAGAR ROAD, VILLAGE SANASWADI, TALUKA SHIRUR, DISTRICT PUNK, MAHARASHTRA. PIN CODE- 412208. THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED: I Field of the invention; This invention relates to a container having lid with spout, made of rigid plastic or the like material. Background of the present invention: A spout is provided in the lid of the container, especially one having a wide outlet, to facilitate pouring of the contents of the container, particularly into another storage facility having a narrow inlet as compared to the outlet of the container. However, such spouts may pose problem while stacking such containers one over the other. An important aspect in the container design is its stackabilily. not only with respect to the containers of similar description and/or type but also other containers of different description and/or type. In order to allow this kind of stackability, the aforesaid spout is made collapsible so that when not in use it can be collapsed down to atleast make it flush with the lid surface on which the bottom of the upper container rests. In order to achieve this function the spout area and / or its walls are made of a flexible material in contrast to the rigid surface of the lid. for this the lid assembly is made of two different materials. However, assembling of the said collapsible spout known in the prior art with the lid requires bonding of two different plastic materials. Sometimes this bond is not strong enough to hold the spout with the lid and when a vertical pressure is applied on it while collapsing; it gets detached from the lid and falls inside the container. Also improper bonding leaves some pores through which the contents of the container can leak. This can be avoided if lid and the spout are molded in the same material. But if the lid is moulded in the same material as of the spout i.e. in flexible material like LDPE. EVA etc., it will lose the strength and if the spout is moulded in the same material as the lid i.e. in lesser flexible materials like Polypropylene or rigid or hard material, it will adversely affect its collapsibility. 2 30 AUG 2007 Object of the present invention: The present invention obviates the aforesaid drawbacks by providing a container having a lid with spout integrated with the lid by making both of the same material e.g. of polypropylene but wherein the spout is made collapsible by providing a thin walled concavity e.g. in the form of a concave diaphragm (with reference to the lid surface) around it. Summary of the present invention: This invention proposes a container, having lid with spout made of rigid (or hard) plastic or the like material, characterized in that the top surface of the lid or the part thereof is flexible in upward / downward direction and in its normal position rests in the downward direction; and the spout is an integral part of the said flexible top surface of the lid. Further the said flexible surface is thin and has concavity and the spout is at the center of the concavity. Description of the present invention: The invention will now be explained with reference to drawings accompanying the provisional as well as those accompanying the complete specification. However, the said figures only illustrate but in no way limit the present invention. Numerals have been used in the drawings to indicate the various parts of the container having lid with spout according to this invention and the same numerals are used to denote the same parts. In the said drawings. Fig. 1 shows the plan and fig. 2 shows the sectional elevation of the lid (I) with spout (6) according to this invention wherein, the spout (6) is in the normal position. i.e. the flexible top surface herein called the diaphragm (4) is concave and rests in the downward direction. The lid (I) has the outer rim (2) and top surface (3). The spout (6) is at the center of the diaphragm (4) and they are integral part of the top surface (3). Fins (5) are 3 30 AUG 2007 provided along the internal circumference at the bottom of the spout (6). Angular teeth (7) are provided along the external circumference at the bottom of the spout (6). In the said drawings. Fig. 3 shows the plan and fig. 4 shows the sectional elevation of the lid (1) with spout (6) according to this invention wherein, the spout (6) is in the intermediate position, i.e. the diaphragm (4) is Hexed but the spout (6) is still below the same plane as the outer rim (2) of the lid (1). In the said drawings, Fig. 5 shows the plan and fig. 6 shows the sectional elevation of the lid (I) with spout (6) according to this invention wherein, the diaphragm (4) is convex and the spout (6) is in the drawn-up or pulled-up position, i.e. above the plane of the outer rim (2) of the lid (I). In the said figures. Fig. 7 shows the sectional elevation of the spout cap (8) with its handle (9). The said cap (8) has thin projection (11) projecting downward from the bottom (inside) surface (8A). Two half rings (10) are connected to the bottom circumference of the cap's (8) side walls by means of thin / weak bridges (12). The said bridges (12) have an orientation in a direction which is circumferenlially opposite to the direction of the angular teeth (7) on the spout (6). as shown in fig. I, fig. 2 and fig. 3. In the said figures. Fig. 8 shows the sectional elevation of the cap (8) when assembled or screwed on the spout (6) with the help of threading on the spout (6) and cap (8) which mesh which each other. 4 30 AUG 2007 In the drawings accompanying the complete specification, Fig. 9 shows the sectional elevation of the diaphragm (4) with spout (6) in its normal position. It is fitted with cap (8). The said assembly shows fins (5). angular teeth (7). two half ring (10). thin projection (11) and thin / weak bridges (12). In the said figures. Pig. 10 shows the perspective view of the diaphragm (4) with spout (6) according to the present invention wherein, diaphragm is in its normal concave position. Fig. 1 1 shows the perspective view of the cap (8) according to the present invention wherein, i! has handle (9). two half rings (10) and thin / weak bridges (12). Working of the present invention: The spout (6) is made collapsible by providing a thin walled concavity in the form of a diaphragm (4) (with reference to the remaining lid surface) around the spout (6). The thickness of the said diaphragm (4) is preferably between 0.40 mm to 1.50 mm. The depth of the concavity of the said diaphragm (4) should be is preferably be between 5.00 mm and the diameter of the said diaphragm (4). As shown in figs. I & 2. the upper edge of the spout (6), which is at the center of the said diaphragm (4). is in its normal position either flushed with or lower than the outer lid surface (3). As shown in fig. 3 & 4. when the spout (6) is pulled upwards, the thin walled diaphragm (4) flexes by coming to an intermediate position and on continuing the pressure in the vertical direction it toggles to a position where the diaphragm (4) is convex, thus bringing the spout (6) above the level of the top lid surface (3), as shown in fig. 5 & 6, so that the contents within the container can be conveniently poured out. 5 30 AUG 2007 In order to collapse the diaphragm (4) back to the concave position, a vertical pressure is applied on the spout (6) in the downward direction, thereby allowing the diaphragm (4) to toggle back to its normal concave position (4) and thereby moving the spout (6) below the plane of the top lid surface (3), as shown in figs. I & 2. In a preferable embodiment, number of fins (5) is provided at the bottom and around the internal circumference of the spout (6) to break the flow of the contents, particularly liquids, creating a passage for the atmospheric air to enter in. This avoids creation of the partial vacuum inside the container when the contents are flowing out, resulting in an unhindered and continuous flow of contents. When the spout (6) is capped with cap (8) the thin / weak bridges (12) jump over the angular teeth (7). thus interlocking the cap (8) with the spout (6). When the spout (6) is uncapped the bridges (12) break because of the force exerted on them by the angular teeth (7) during the said act of uncapping, breaking away the two half rings (10) from of the spout (6). This indicates that the spout has been tampered, thereby making the said two half rings (10) are tamper-evident. r'urther when the spout (6) is capped with cap (8) the thin projection (II) that is projecting downward from the bottom inside surface of the cap all around it but slightly away from the side walls of the cap (8) helps the cap (8) to tightly fit over the spout (6). thus preventing the leakage of contents of the container through the spout (6). The cap (8) has a handle (9) over its top outer surface that is used to pull the spout (6) in the upward direction. 30 AUG 2007 Advantages of the invention: following are some of the advantages of the lid with spout according to this invention: Heavy reduction in cost due to - a. reduction in inventory b. reduction in number of moulds c. low rejection rate d. reduction in machinery e. no assembling require Wc Claim: I) A container, having lid with spout made of rigid plastic or the like material, characterized in that the top surface of the lid or the part thereof is flexible in upward / downward direction and in its normal position rests in the downward direction; and the spout is an integral part of the said flexible top surface of the lid. 2.
