  The present invention relates to a lid for a container and a combination of a container and a lid. The lid provides a structure or mechanism for piercing the membrane that seals the top opening of the container. The membrane generally has the form of a foil, film or the like. The lid may include a sip opening. The sluice allows access for consumption of the contents of the container when the membrane is pierced. Preferably, the action of the lid to puncture the membrane opens the sip at the same time. Preferably, the operation includes rotation of a part of the lid with respect to the other part of the lid. The contents may include but are not limited to coffee, hot chocolate, cappuccino, liquid desserts and semi-liquid, high liquid foods.

  The lid of the present invention is designed to be attached to the top of a container such as a beverage container, the container having a membrane that seals and covers its top opening. The lid preferably includes a body and a slick formed in the central portion. The central part has a grip part on the top surface for a person to grip the central part with a finger and turn the central part. A protrusion extends downward from the bottom surface of the central portion toward the membrane. As the center is rotated, the protrusion is pushed toward the membrane until the protrusion punctures the film. Preferably, the lid includes a closable opening through which a person drinks after the membrane has been punctured. The opening is selectively opened and closed by rotating the central part.

  In one form thereof, the present invention relates to a container having a closed top and a lid over the container. The lid has a sluice and a mechanism for opening the closed top of the container and simultaneously providing access to the contents of the container through the slick.

  In another aspect, the present invention relates to a container having a closed top and a lid over the container. The lid is a mechanism that moves the sliding cover away from the sliding opening with a reclosable sliding cover and opens the closed top of the container, thereby simultaneously the contents of the container through the sliding opening. And a mechanism for providing access to the network.

  In another form, the present invention relates to a lid for a container having a membrane covering the top opening of the container. The lid has a fixed-side main body and a rotatable central portion. The central portion has an upper surface that is used by the user to grip and rotate the central portion. The underside of the body includes a cam that faces the container membrane, and rotation of the central portion moves the protrusion engaged by the cam toward the membrane of the container, causing the membrane to be pierced.

  In one advantageous form, the projection is arranged on the arm, the arm being radially spaced from the central part and including a groove facing away from the direction of the projection. The groove accepts insertion of a cam that extends downward from the bottom surface of the lid body. The cam is tilted so that rotation of the central portion allows the radially spaced arms with protrusions to move downward.

  The present invention also includes a lid for a container having a membrane. The lid includes a stationary main body and a member rotatable with respect to the main body. The rotatable member has an arm radially spaced from its main portion and includes a protrusion. The protrusions pierce the membrane when a rotatable member is placed on the container and rotated.

  The present invention also includes a lid for a container having a membrane. The lid includes a body having a top surface and a bottom surface. The bottom surface has an inclined surface extending downward therefrom. The lid further includes a portion that is rotatable relative to the body. The arm is radially spaced from the rotatable portion and has a protrusion that faces away from the bottom surface of the body. The arm contacts the inclined surface, so that rotation of the rotatable portion causes the arm to ride along the inclined surface, thereby moving the projection of the arm away from the bottom surface of the main body and toward the membrane cover. .

  The present invention also includes a lid for a container having a membrane cover. The lid includes a main body and a rotatable central portion. The body includes a slick mouth. A slid cover located in the body below the throat is connected to the center, so that rotation of the center causes both the closing and opening of the sill by the slid cover. Preferably, the same rotational movement of the central part that causes the projection to open a hole in the membrane also moves the sliding cover to open the sliding opening.

  In a further aspect of the invention, the slid lid has a body and a rotatable central portion. The central part pierces the membrane below it. The slid lid includes a package integrity tab between the rotatable central portion and the body.

  The present invention will now be described with reference to the drawings. Like numerals represent like elements throughout the figures.

  Referring now to FIG. 1, the container 10 is shown as a cup 11 sealed by a membrane 12. The cup 11 can be made of any suitable material including paper, cardboard, Styrofoam ™ and various thermoplastics. The membrane 12 can be made of any suitable material including metals and plastics. The container 10 is designed to contain a liquid or a flowable semi-liquid.

  The lid 20 is disposed on the top of the cup 11 and functions as an overcap covering the membrane 12. The lid 20 includes a main body 30 on the fixed side and a rotatable member or central portion 40. As will be described later, the main body 30 has an opening 31 for a user to sip a beverage from the container 11 after the membrane 12 is pierced.

  The main body groove 33 is positioned at a radial position adjacent to the outer periphery of the rotatable central portion 40. The body groove 33 accumulates liquid that has been inadvertently spilled between the central portion 40 and the body 30 after the membrane 12 has been drilled.

  The central portion 40 has a top surface 41 facing outward. The top surface 41 has two actuable surfaces 42 that are located on opposite sides of 180 ° and are separately recessed and of sufficient size, and these surfaces 42 allow the user to grab the top surface 41 and center 40. Makes it possible to turn. A depression having the form of a concave depression center 43 receives the user's nose when sipping liquid from the container 11.

  Before the central portion 40 is first rotated, the package integration tab 44 spans between and is secured to both the body 30 and the central portion 40. After the central portion 40 is first rotated, the tab 44 is separated between the body 30 and the central portion 40, indicating that the container 10 has been opened in the past.

  Referring now to FIGS. 4 and 5, the body 30 has an inwardly facing surface 34. The surface 34 faces downward toward the membrane 12. Extending from the surface 34 are an inclined surface having the form of an inclined cam 35, stop bodies 36, 39 and a plurality of fins 37 defining a shallow compartment 38.

  Referring now to the central portion of FIG. 5, the central portion 40 has a downwardly facing surface 45. An arm 46 extending in the circumferential direction is radially spaced from the main portion of the central portion 40 and is fixed to the main portion of the central portion 40 via a support body 47. One end of the support body 47 is fixed to the main portion of the central portion 40 by the bracket 54, and the other end is fixed to the main portion of the central portion 40 by the bracket 54 ′. The end of the arm 46 furthest from the support 47 includes a downwardly extending protrusion 48. The protrusion 48 extends downward from the arm 46 toward the membrane 12 when the lid 20 is disposed on the cup 11.

  A groove 49 is formed from a pair of ridges extending upward from the arm 46. The groove 49 is dimensioned to accept the insertion of the inclined cam 35.

  The slidable cover 50 is also radially spaced from the main part of the central part 40 and fixed to the main part of the central part 40 via a plurality of supports 51. The soot cover 50 has an upwardly facing surface 50a (FIG. 6) that covers the opening 31 when the container 10 is in the closed state (as shown in FIG. 1).

  A protrusion 52 extends from the slid cover 50 in an upward direction away from the membrane 12 toward the surface 34 of the body 30 facing inward and downward. The protrusion 52 is elastically formed on the sliding cover 50 and / or is biased toward the sliding cover 50. The protrusion 52 is selectively disposed in one of the plurality of shallow compartments 38 defined by the plurality of fins 37. Due to the elasticity characteristics of the material of the central part 40 including the slid cover 50 and / or the biasing characteristics of the protrusions 52, the protrusions 52 are urged to one of the plurality of compartments 38 as the central part 40 rotates. It is possible to ride along one of the surfaces of the fin 37 and forcibly eject it from the compartment. As a result, the combination of the fin 37 and the protrusion 52 provides a resistance that limits the free rotation of the central portion 40.

  Referring now to FIGS. 2a, 2b, 3a and 3b, particularly FIGS. 2a and 3a in the initial position, before opening the container 10 for the first time, the lid 20 is in its closed state, ie the slid cover 50 is The opening 31 is closed and the package integration tab 44 attached to both the main body 30 and the central portion 40 at this time indicates that the sliding lid 20 has not been opened first. Initially, the inwardly extending protrusion 48 is in the uppermost retracted position relative to the membrane 12. In order to pierce the membrane 12 covering the opening of the container 10, a person grasps the central portion 40 with his finger by pressing the depressed working surface 42 and provides sufficient pressure clockwise as indicated by the arrow 60. Act. The rotation of the central part 40 in the direction 60 first separates the connection of the package integration tab 44 between the main body 30 and the central part 40 and at the same time tilts the arm 46 separated to the outer periphery with the groove 49. Along the cam 35, the projection 48 is pushed inward toward the membrane 12 to finally make a hole in the membrane 12. As the central portion 40 is rotated, the cover 50 is rotated away from the opening 31. In the fully open position, the end face 53 of the cover 50 contacts the stop 39 as shown in FIG. 3b. Advantageously, the incision made in the membrane by the protrusion 48 is close to the opening 31, which makes it easier for a person to drink beverage from the opening 31 by tilting the container 10 and allowing a person to drink from the opening 31. Enable.

  The slid lid 20 can be closed by rotating the central portion 40 in the opposite direction, as shown by arrows 61 in FIGS. 2b and 3b. The rotation of the central portion 40 in the direction 61 returns the cover 50 so as to cover the opening 31. In the fully closed position, the cover end surface 55 is in contact with the stop body 36, and the end surface 54 is in contact with the stop body 39.

  It will be apparent to those skilled in the art that the slid lid provides advantages and features not found in conventional slid lids. For example, in a preferred embodiment, the slid lid allows the membrane sealed container to remain closed and sealed until the user selectively rotates the rotatable center. Its central rotation simultaneously pierces the underlying membrane, opens a sip, and allows the user to rinse the beverage from the container. The user can then rotate the slid lid in the opposite direction to close the opening and prevent accidental spills from the container. In addition, the container includes a package integration element having the form of a tab. This provides an indication that the container has not been opened first.

  Although the present invention has been described with respect to its embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made to these preferred embodiments without departing from the scope and spirit of the invention.
