Definitions

  • This invention relates to a paper container in which an opening plug is secured to an opening portion formed in a container material having thermoplastic resin layers on the front and rear surfaces thereof.
  • an opening portion 22 is formed with an opening hole 24, i.e. as the opening portion 22 in a container material 23, a barrier film 25 is attached to the rear surface of the container material 23 so as to cover the opening hole 24 (Refer to Fig.
  • an opening plug 26 includes: a tubular holder 28 having a flange portion 27 attached to the outer peripheral edge portion of the opening hole 24 at the outer periphery of the bottom end thereof; and a tubular cutting member 29 being vertically movably coupled into the holder 28 and having blade portions at the bottom end thereof.
  • the holder 28 is formed with a cut-away guide 30 from the top end to the downward direction and an eaves-shaped projection 31 engageable with the cut-away guide 30 is formed at the top end of the cutting member 29 (Refer to Fig. 6).
  • the cutting member 29 coupled into the holder 28 is pushed down by finger to the lower limit of the cut-away guide 30 formed in the holder 28, whereby the blade portions provided at the lower end of the cutting member 29 project from the bottom end of the holder 28 to cut the barrier film 25 of the opening portion 22, so that opening of the opening portion 22 can be achieved.
  • the end of the cutting member 29 like this does not always project from the holder 28 before and after the opening.
  • the opening portion 22 formed in the container material 23 is completely punched out, whereby, when the barrier film 25 covering the opening hole 24 is a film having a high extensibility, if the cutting member 29 is pushed down to open the container, then the barrier film 25 is extended and only portions of the barrier film 25 in contact with the blade portions are notched and the barrier film 25 tends to be left uncut. Furthermore, opening is carried out by pushing the cutting member 29 into the holder 28, and, as the cutting member 29 is pushed in, the cutting member 29 sinks into the holder 28, whereby, it is cramped to push the cutting member 29 in, so that opening is troublesome to do.
  • the present invention has a problem to solve the above-­described disadvantages.
  • the present invention is of such an arrangement that a paper container with an opening plug features that the opening plug is secured to an opening portion formed in a container material having thermoplastic resin layers on the front and rear surfaces thereof, wherein: in the opening portion, a punching line forming a contour of a hole is formed with a part thereof being left, and a barrier film is attached to the rear surface of the container material so as to cover the punching line; and the opening plug includes: a tubular holder having a flange portion attached to the outer peripheral edge portion of the punching line, the flange portion being provided on the outer periphery of the bottom end thereof; and a cutting member having blade portions different in length from one another, connectingly provided in the holder by a breakable connecting portion, when the connecting portion is broken by the push-down of a push-move portion, the cutting member is coupled into the holder, the cutting member projecting from the bottom end of the holder by the push-down of the push-move portion and cutting the barrier film covering
  • the opening portion formed in the container material forms the punching line defining the contour of the hole in the container material and the barrier film is attached to the rear surface of the container material so as to cover the punching line, whereby the container material is present in the area surrounded by the punching line and the barrier film is exposed only at the portion of the punching line.
  • the cutting member before the opening, the cutting member is connected to the holder through the connecting portion, whereby, during the preservation of the container, this connecting portion prevents the cutting member from sinking into the supporting holder, the blade portions of the cutting member are prevented from reaching the barrier film, and, during the opening, the cutting member is pushed down by finger to be coupled into the holder and received in the holder, so that the cutting member is not restricted by the holder when the cutting member is lowered.
  • numeral 1 is a main body of paper container
  • numeral 2 is a container material forming the main body 1 of paper container
  • this container material 2 is provided at the front and rear surfaces of a paper layer 3 with thermoplastic resin layers 4, 5.
  • Denoted at numeral 6 is a top wall of the main body 1 of paper container and numeral 7 is a top seal portion.
  • Indicated at numeral 8 is an opening portion formed in the container material 2 positioned at the top wall 6 of the main body 1 of paper container.
  • This opening portion 8 forms a punching line 9 on the container material 2 defining a contour of an opening hole, and the container material 2 is attached at the rear surface thereof with a barrier film 10 such as an aluminium foil so as to cover this punching line 9.
  • a barrier film 10 such as an aluminium foil
  • Designated at numeral 12 is an opening plug secured onto the opening portion 8 of the front surface of the container material 2 from outside.
  • This opening plug 12 includes: a tubular holder 14 provided at the outer periphery of the bottom end thereof with a flange portion 13 which is attached to the outer peripheral edge portion of the punching line 9; a cutting member 15 supported by the holder 14; and a cap 16.
  • the holder 14 is formed on the outer periphery thereof with threads 17 which are threadably coupled to a cap 16.
  • the cutting member 15 is of such an arrangement that a plurality of blade portions 19 different in length at least within a range shorter than the tubu length of the holder 14 are provided at the lower end of a tubular push-move portion 18 which can be coupled into the holder 14 and has a contour at an end face that is substantially similar in shape with the punching line 9.
  • a connecting portion 20, which is attached to the holder 14, is easily breakable by push-cut made between the top end of the holder 14 and the bottom end of the push-move portion 18 in a state where the blade portions 19 are contained in the holder 14.
  • the cutting member 15 is supported on the holder 14 by the connecting portion 20 in such a state that the push-move portion 18 projects from the top end of the holder 14 and the blade portions 19 are housed in the holder 14.
  • the connecting portion 20 is broken due to the push-down force, whereby push-move portion 18 is coupled into the holder 14, so that the blade portions 19 formed at the bottom end of the push-move portion 18 project downward from the bottom end of the holder 14.
  • Designated at numeral 21 is a flange portion projectingly provided at the outer periphery of the top end of the push-move portion 18, and, when the push-move portion 18 is pushed down to be coupled into the holder 14, the flange portion 21 is adapted to abut against the top end of the holder 14.
  • a distance, for which the blade portions 19 project from the bottom end of the holder 14, is equal to a distance, for which the push-move portion 18 enters the holder 14, and, when the push-move portion 18 is pushed down and the flange portion 21 is abutted against the top end of the holder 14, a distance, for which the blade portions 19 project from the bottom end of the holder 14, is a distance necessary and sufficient for cutting the barrier film 10 exposed in the punching line 9 of the opening portion 8.
  • the outer diameter of the push-move portion 18 is formed such that, when the push-move portion 18 is pushed into the holder 14, the push-move portion 18 holds such a degree of adhesion that the push-move portion 18 does not freely, vertically move in the holder 14. Or, the outer diameter of the push-move portion 18 may be gradually increased although the degree of increase is slight.
  • the push-move portion 18 of the cutting member 15 is projected by the connecting portion 20 upwardly from the top end of the holder 14, and the blade portions 19 are held in a state of being contained in the holder 14, so that there is no possibility that the barrier film 10 exposed in the punching line 9 of the opening portion 8 is damaged by the blade portions 19.
  • the cap 16 is removed from the holder 14, the push-move portion 18 of the cutting member 15 is pushed down by finger to cut the connecting portion 20, the push-move portion 18 is coupled into the holder 14, and is made to sink by the length thereof.
  • the extension of the barrier film 10 due to the pressing of the blade portions 19 is limited to the portion of the barrier film 10 exposed in the punching line 9, the extension has almost no influence on the cutting of the barrier film 10 by the blade portions 19, and the barrier film 10 can be reliably cut.
  • the cutting member is supported by the connecting portion such that the push-move portion of the cutting member projects from the top end of the holder and the blade portions are contained in the holder, there is no possibility that the barrier film is damaged by the blade portions before the opening. Furthermore, to open the container, it suffices that the push-move portion of the cutting member, which is projected above the holder and supported, is pushed down by finger to be pushed into the holder, the blade portions provided at the forward end cut the barrier film in the punching line, so that the opening portion can be opened.
  • the opening is far easier than the opening by use of the conventional opening plug, even if the barrier film is a film having a high extensibility, the extension of the barrier film due to the pressing of the blade portions is limited to the portion of the barrier film exposed in the punching line, and the extension has almost no influence on the cutting of the barrier film, so that the barrier film can be reliably cut to achieve the opening. Furthermore, the push-move portion is closely fitted into the holder, so that there is no possibility that it falls off during use. Further, the holder and the cutting member can be formed integrally with each other, whereby the holder and the cutting member are formed integrally with each other, so that the manufacturing process can be shortened by this, thus enabling to improve the working efficiency.
