Definitions

  • the present invention relates to a resin cap having excellent sealing reliability and can openability, and more specifically, to a resin cap which can form reliable sealing and can be easily and exactly opened and has tamper-evident (TE) characteristics.
  • TE tamper-evident
  • a resin cap can be integrally molded, and has excellent moldability and flexibility, it can be fixed to a mouth portion of a container by a stopping operation and has been used heretofore in various forms.
  • JP 51-10555 describes an unfair act-preventing closure composed of a synthetic resin having a handle on the outer surface of a skirt wall.
  • the handle of this closure is spaced from an outer circumferential surface of the skirt wall and surrounding it. It is not a complete ring but arcuate and both its end portions are firmly fixed to the outer surface of the skirt wall.
  • the inner surface of the handle is connected to the outer surface of the skirt wall by a plurality of easily breakable connecting pieces formed circumferentially at suitable distances.
  • the prior art is significant because it provides a plastic cap which can be opened by hand without requiring any particular tool such as a cap opener and to which an unfair act-preventing function is imparted.
  • a sealing reliability Circumferential protrusions are formed on the inner surface of the skirt wall, and when these protrusions are sealed with the neck portion of the container, the container is sealed.
  • the skirt wall cannot easily be turned up, and the openability of the can becomes unsatisfactory. Since the protrusions for securing sealability are not formed over the entire circumference of the inner surface of the skirt wall, the closure of the above prior art has unsatisfactory sealing reliability.
  • Another object of the invention is to provide a resin cap in which in a stopping action, a ring-like member protects a skirt portion of a cap proper, in a closure-closed condition, the ring member intimately contacts the outer surface of the skirt portion of the cap proper to maintain sealability, the ring-like member is removed at the time of opening the cap, the skirt portion can be easily removed from the mouth portion of the container, and in addition, the ring-like member has tamper-evident characteristics.
  • a cap made from resin comprising:
  • an opening tab is preferably formed in a part of the ring-like member.
  • the skirt portion of the cap proper and the ring member are preferably formed by injection- or compression molding them integrally, thereafter making a cut by a cutter between the two to separate a portion excluding a bridge portion or further a connecting portion.
  • the cap of the present invention is typically composed of a skirt portion in the cap proper and a ring member provided so as to cover the outer surface of the skirt portion, the skirt portion of the cap proper is provided with a plurality of slits extending in an axial direction at intervals in a circumferential direction, the skirt portion of the cap proper is separated from the ring member via a cutting face, the skirt portion and the ring member are integrally formed via a plurality of frangible bridges or further connecting portions on the upper side or under side of the cutting faces, and the outside surface of the skirt portion of the cap proper and the inner surface of the ring member are intimately contacting at a portion of the cutting faces.
  • the skirt portion of the cap proper is provided with a plurality of slits extending in an axial direction at intervals in a circumferential direction whereby the skirt portion is broadened diametrically outwardly at the time of cap opening so that the cap proper can be easily removed from the mouth portion of the container.
  • the skirt portion of the cap proper is separated from the ring member via a cutting face, but they are integrally molded through a plurality of frangible bridges or further connecting portions on the upper side or the lower side from the cutting face and the outer surface of the skirt portion of the cap proper and the inner surface of the ring member are contacted intimately at a portion of the cutting face.
  • the skirt portion of the cap proper at least in the closed state is circumferentially bundled and fixed by the ring member so that the skirt portion is prevented from broadening outwardly and accurate sealability against the mouth portion of the container is maintained.
  • This feature is especially important in the case of the cap of the present invention which is provided with axially extending slits in the skirt portion.
  • the slits at the skirt portion act so as to weaken the engaging state between the mouth portion of the container and the protrusions of the skirt portion, but as a result of the action of circumferentially bundling and fixing by the ring member, the engaging state becomes firm and accurate.
  • an opening tab is formed in a part of the ring member, divergence occurs between the ring member and the skirt portion at the cutting face by pushing up or down the tab whereby the bridge portion connecting the cap proper with the ring member is cut off by a shearing force. Because slits are formed in the skirt portion of the cap proper, when the ring member is removed from the skirt portion, the skirt portion is freely broadened diametrically outwardly. Thus, the cap proper is easily eliminated from the mouth portion of the container and can be opened easily without using a tool.
  • the strength of the opening tab is reinforced, or its position can be clearly shown.
  • the skirt portion of the cap proper and the ring member are typically formed by integral injection or compression molding, forming slits by a cutter between both to separate a portion excepting the bridge portions or further connecting portions, they can be produced by using a mold composed usually of a core and a cavity, and a molding procedure is easy.
  • the frangible bridge portions may be formed, whereby the cap proper may be separated from the ring member in opening the cap.
  • the cap proper may be separated from the ring member in opening the cap.
  • tamper-evident characteristics become more marked.
  • the lower end of the skirt portion is pushed up by a finger whereby by the existence of slits, the cap proper can be easily opened.
  • connecting portions for connecting both may be positioned between the skirt portion of the cap proper and the ring member, and in opening the cap, the bridge portions are broken by pushing up or down the tab. Thereafter, by lifting the ring member, the engagement between the skirt portion of the cap proper and the mouth portion of the container can be released.
  • the ring member can be utilized as an opening handle of the cap proper.
  • An inner ring which is engaged with the inner circumferential side of the mouth portion of the container may be formed in the top panel portion.
  • sealing may be performed at the inner circumferential side of the mouth portion of the container, and the sealing advantageously becomes more accurate.
  • the lower end of the ring member may be positioned below the lower end of the skirt portion of the cap proper. By so doing, the lower end of the skirt portion of the cap proper is hidden by the ring member.
  • the bridge portions necessary break. Therefore, tamper-evident characteristics can be increased.
  • the lower end of the ring member and the lower end of the skirt portion of the cap proper may be provided so that they are positioned on the same horizontal plane. In this case, when empty caps are loaded, a load, etc. is added to the bridge portions to prevent breakage.
  • a weakened portion such as a cut, can be formed to display cap opening at a lower part of the ring member in a direction of about 90°C with respect to the tab of the ring member.
  • partial weakened portions may be formed.
  • the top panel portion of the connecting portion side may be provided with partial weakened portions.
  • the top panel portion of the cap is cracked, and one can learn the performance of an unfair opening.
  • the inner ring can have an inclined end edge so that the inner ring is relatively long on the tab side, and relatively short on the connecting portion side.
  • the opening of the cap proper can be performed by lifting the ring member from the side of the connecting portions. At the time of opening from the side of the connecting portions, a gas vent from the short inner ring is effectively carried out to effectively prevent blowing of contents, namely blow off.
  • the above prevention of blow off is also effectively carried out by providing weakened portions on the inner surface of the inner ring on the side of the connecting portions. This makes the deformation of the inner ring on the side of the connecting portions easy, and the release of the gas inside the container is carried out effectively via the inner ring.
  • a gas-barrier material can be insert-molded in the top panel portion of the inner surface of the inner ring. This makes it possible to prevent the permeation of gas through a plastic cap wall, and the preservability of contents can be increased.
  • a total circumferential ring or intermittent rings which project upwardly into an outer circumferential portion of the top panel portion may be formed, whereby it can be prevented from causing the trouble when the containers with the cap are loaded with each other.
  • the contained solution is a carbonated beverage, doming occurs on the top panel of the cap. Accordingly, when such containers are loaded, the top panel portion which has been domed is pressed, and the engagement protrusion of the skirt portion is broadened and the sealing reliability is decreased, and as a result of forming the above ring, such an inconvenience can be prevented.
  • the cap of this invention in the side view (Fig. 1) showing one example of the cap of this invention, the bottom view (Fig. 2), the A-A' sectional view of Fig. 2 (Fig. 3), the sectional view (Fig. 4) shown by A-B section in a condition in which the cap is mounted on the mouth portion of the container, and the upper surface view (Fig. 5), the cap of this invention, roughly speaking, consists of a cap proper 1 and ring member 2.
  • the cap proper 1 is composed of a top panel portion 3 and a skirt portion 4 suspending from the outer circumference of the panel 3.
  • protrusions 7 which are engaged with concave portions 6 on the outer circumferential side of the mouth portion 5 of the container are formed in the inner circumference of the skirt portion 4 so that the mouth portion 5 of the container is intimately contacted with the inside surface of the top panel portion 3 to perform sealing.
  • the top panel portion 3 has formed therein an inner ring 8 to be engaged with the inner circumferential side of the mouth portion 5 of the container whereby sealing is carried out in the inner circumferential side of the mouth portion 5 of the container to make the sealing more accurate.
  • the ring member 2 is not divided and it is provided so as to cover at least a part of the outer surface of the skirt portion 4 in the form of a continuous ring.
  • the skirt portion 4 of the cap proper 1 covered with the ring members 2 is provided with a plurality of slits or cuts 9 extending in an axial direction at intervals in a circumferential direction.
  • the skirt portion 4 of the cap proper 1 and the ring member 2 are separated via the cutting face 10, and the skirt portion 4 and the ring member 2 are integrally formed via a plurality of frangible bridge portions 11 and unbreakable connecting portions (hinge) 12 which are below the cutting face 10.
  • the outer surface of the skirt portion 4 of the cap proper and the inner surface of the ring member 2 are contacted intimately with each other at a portion of the cutting face 10 in a condition in which the cap proper 1 is applied to the mouth portion 5 of the container (Fig. 4).
  • An opening tab 13 protruding diametrically outwardly is formed at a part of the ring member 2, and in opening the cap, the tab is held so that the ring member 2 may be pushed up or down.
  • a rib 14 extending diametrically is formed in the opening tab 13 to reinforce the opening tab 13 or display its position.
  • the number of cuts 9 provided or the transverse gaps of these cuts may be properly determined.
  • the number of cuts 9 provided in the skirt portion 4 may differ depending upon the diameter of the cap, but it is preferably 2 to 20, especially 8 to 12.
  • the skirt portion 4 of the cap proper By contacting the skirt portion 4 and the ring member 2 intimately at a portion of the cutting face 10, the skirt portion 4 of the cap proper is circumferentially bundled and fixed at least in a cap closed condition with the ring member 2 whereby the skirt portion 4 is prevented from broadening outwardly, and accurate sealing with respect to the mouth portion of the container can be maintained.
  • this intimate contacting condition is particularly important.
  • the cuts 9 in the skirt portion 4 act to weaken the condition of engagement between the concave portion 6 of the outer circumference of the mouth portion of the container and the protrusion 7 of the skirt portion 4. But when the force of bundling and fixing acts by the ring member 2, the engagement condition becomes firm and accurate.
  • the plurality of frangible bridges 11 or the linking portions 12 are provided for linking the skirt portion 4 of the cap proper and the ring member 2 below the cutting face 10, the engraving of the cutting face 10 is prevented from adversely affecting the bridge portions 11 or the connecting portions 12. Because at the time of closing the cap the outer surface of the skirt portion 4 of the cap proper is contacted intimately to the inner surface of the ring member 2 at a portion of the cutting face 10, an outer force is prevented from acting on the breakable bridge portions 11, and the protection of the bridge portions 11 is perfect at the time of closing the cap.
  • the intimate contacting condition of the skirt portion 4 of the cap proper and the ring member 2 via the cutting face and the formation of the bridge portions 11 and the connecting portions 12 may be carried out by integrally injection molding or compression molding both, thereafter forming a cut between both by means of a cutter to separate a portion excluding the bridge portions 11 and the connecting portions 12. Therefore the cap of the present invention can be produced with good efficiency and within a short period of time by usually using a mold composed of a core and a cavity, an advantage may be obtained in that the accuracy of each part of the cap is high, and the occurrence of poor goods is small.
  • the number of the bridge portions 11 provided between the skirt portion 4 of the cap proper and the ring member 2 is such that the skirt piece 4a between adjoining cuts 9, 9 and the ring member 2 is connected via at least one bridge portion 11.
  • the position of providing the bridge portion11 may be variously provided. For example, as shown in Fig. 2, one bridge portion may be provided in a skirt piece 4a, or two bridge portions may be provided on both ends of the skirt piece 4a.
  • the position and the number are not particularly limited so long as at the time of closing the cap, the breakage of the bridge portions is prevented and at the time of opening the cap, the bridge portions can be easily broken.
  • the cross-sectional area of the bridge portion 11 in its direction of the cutting face 10 of the bridge portion 11 is preferably 0.1 to 0.8 mm 2 , especially 0.2 to 0.4 mm 2 , per one bridge portion.
  • An opening tab 13 protruding diametrically outwardly is formed at a part of the ring member 2. This opening tab 13 is positioned in an opposite direction (180° direction) with respect to the connecting portion 12. By pushing up or down the opening tab 13, a divergence occurs between the ring member and the skirt portion at the cutting face, and the bridge portion 11 linking the cap proper 1 and the ring member 2 is cut off under a shearing force.
  • Fig. 6 shows the state of lifting the ring member 2. Since the cutting face 9 is provided in the skirt portion 4 of the cap proper, when the ring member 2 is removed from the skirt portion 4, the broadening of the skirt piece 4a in a diametrically outward direction becomes free and the cap proper 1 can be easily eliminated from the mouth portion 5 of the container. Hence, the container can be easily opened without using any particular tool. Since in Fig. 6 the ring member 2 is fixed to the cap proper 1 at the connecting portion 12, and is lifted upwardly as a gripping tool, the bridging portion 12 becomes a fulcrum and the cap proper 1 can be easily removed.
  • the bridging portions 11 have already been broken and the ring members 2 can be freely moved up or down. From this state, one can already learn that the cap has already been opened. By breakage and bending at the weakening portion 17, it is learned that the cap is already opened, and therefore tamper-evident characteristics are given.
  • the lower end 15 of the ring member 2 is positioned below the lower end 16 of the skirt portion 4 of the cap proper.
  • the lower end 16 of the skirt portion of the cap proper is hidden by the ring member 2, and therefore, when an attempt is made to open the cap by inserting an instrument into the lower end 16 of the skirt portion, the bridge portions 11 are broken, and the fact of opening the cap can be known and tamper-evident characteristics can be increased.
  • the lower end 15 of the ring member 2 suitably extends downwardly over about 0.8 to 1.2 mm below the lower end 16 of the skirt portion.
  • a weakened portion for displaying cap opening such as a cut 17, in a lower portion of the ring member in a direction of about 90° with respect to the opening tab 13 of the ring member 2.
  • a partly weakened portion namely a groove 18, may be formed on the upper portion of the connecting portion 12, or a weakened portion, namely a cut 19, may be formed in both ends of a lower portion of the connecting portion 12.
  • a partial weakened portion 20 may be formed in the top panel portion 3 on the side of the connecting portion 12. Therefore, when an unfair opening of the cap is carried out by using a tool from the side of the connecting portion 12, the top panel portion 3 of the cap is deformed or broken, and one can learn that the cap has been unfairly opened.
  • an inner ring 8 is formed to have an inclined end edge so that the inner ring 8 is relatively long at 21 on the side of an opening tab 13, and is relatively short at 22 on the side of a connecting portion 12.
  • the opening of the cap proper is carried out from the side of the connecting portion 12 by lifting the ring member 2.
  • the venting of a gas from the shorter inner ring 22 is carried out effectively, and the blowing of the contents, that is to say the blowing off, can be prevented effectively.
  • the above-mentioned prevention of blow off can be effectively carried out by providing a weakened portion 23 on the inner surface of the inner ring 22 on the side of the connecting portion. This makes it easy to transform the inner ring 22 on the side of the connecting portion, and the gas inside the container is effectively released via the inner ring 22.
  • a gas-barrier material 24 may be provided by insert molding in the top panel portion of the inside surface of the inner ring 8. This makes it possible to prevent permeation of the gas through the plastic cap wall and to increase the preservability of the contents.
  • the gas-barrier material include, for example, metal foils such as aluminum foil, and a gas-barrier resin such as an ethylene /vinyl alcohol copolymer, a vinyl chloride resin, a vinylidene chloride resin, nylon resin, and gas-barrier polyesters.
  • an oxygen absorbing layer may be provided in the top panel portion.
  • oxygen absorbing layer iron-type oxygen absorbing agents, for example, dispersed in a resin may be used.
  • a total circumferential or intermittent ring 25 may be formed which protrudes upwardly into an outer cylindrical portion of the top panel portion 3.
  • the upper portion of the cut 9 is exposed to an outside portion as best shown in Fig. 1.
  • the caps of these examples are advantageous in that the contents adhering to the outer circumference of the mouth portion at the time of filling the contents can be washed and removed through the cuts 9.
  • the lower end 15 of the ring member 2 and the lower end 16 of the skirt portion 4 of the cap proper may be provided so as to be positioned on the same horizontal plane. In this case, it is possible to prevent effectively the addition of a load on the bridge portion 11 at the time of loading caps and the consequent breakage of the bridge portion 11.
  • the opening tab is not limited to one piece, but two tabs may be provided in a symmetrical position. Furthermore, more than two tabs may be provided.
  • the cuts 9 may be provided so that they are not exposed into the outer circumference of the skirt portion.
  • the constructions of the individual parts have been the same as explained hereinabove.
  • the outer upper portion 26 of the cut 9 are provided so that it does not reach the outer surface of the skirt portion 4, and therefore, the cut 9 is covered completely with the upper surface of the skirt portion.
  • an advantage is achieved in that dirt is prevented from entering in the cut 9 and the cap is sanitary.
  • the bridge portion 11 and the connecting portion 12 are provided below the cutting face 10, but in the present invention, the bridge portion and the connecting portion may be provided above the cutting face.
  • the constructions of the individual parts are the same as explained hereinabove, but the bridge portion 11 and the connecting portion 12 are formed above the cutting surface 10.
  • the bridge portion 11 can be seen from outside at a first sight, and it becomes advantageous that the fact of opening becomes clearer.
  • the resin used to form the cap are various plastics, such as low-, medium- and high-density polyethylenes, linear low-density polyethylene, polypropylene, thermoplastic polyesters, polyamides, styrene resins, and ABS resin.
  • plastics such as low-, medium- and high-density polyethylenes, linear low-density polyethylene, polypropylene, thermoplastic polyesters, polyamides, styrene resins, and ABS resin.
  • the plastic cap of this invention is prepared by using the above resins, and usually integrating the cap proper and ring member by means of injection molding, compression molding, etc.
  • the cutting face is usually produced by applying a cutting processing after the molding step. Of course, a cutting surface can be formed simultaneously with the molding step.
  • a liner may be applied to the cap proper.
  • low-density polyethylene ethylene copolymers, various rubber or thermoplastic elastomers, acrylic resin plastisol and vinyl chloride resin plastisol.
  • the above-mentioned constructions make it possible to form a sealing structure having sealing reliability at the time of closing the cap, and to open the cap easily without using any particular tool at the time of cap opening.
  • this is advantageous that tamper-evident characteristics are imparted.
  • the ring member protects the skirt portion of the cap proper, in the state of a closure being closed, the ring member contacts intimately with the outer surface of the skirt of the cap proper to maintain sealability, and at the time of opening the cap, the skirt portion can be easily eliminated from the mouth portion of the container as a result of removing the ring member.
  • the ring member has tamper-evident characteristics.
