Definitions

  • the present invention relates to a straw for beverage for drinking liquid beverage by inserting the straw into the straw in­serting opening of a paper container in which the liquid beverage is sealed and more particularly to a straw for drinking beverage wherein an air passage is formed in the straw inserting opening for balancing internal and external pressure of the container when the straw is inserted into the container.
  • a straw which is improved of the above problem, there is a straw wherein a groove is concavely provided in the outer wall portion of the straw which comes in sliding contact with the sealing film of the straw inserting opening of the container so as to form an air passage in the straw inserting opening, thereby causing the internal and external pressure of the container to balance while sucking to drink the liquid beverage (for example, refer to officialgazette of Japanese Laid-Open Utility Model No. 61-113681 (1986) and Japanese Laid-Open Utility Model No. 61-149575 (1986).
  • any straw for drinking beverage which is formed with an air passage to balance the internal and external pressure of the container during sucking to drink beverage is partially provided with a groove concavely on the outer wall of the straw and it was necessary to process under pressure a fine groove in a straw of small diameter normally made of synthetic resin. This involved a difficul­ty in finishing and a problem of spoiled external appearance of the straw.
  • the present invention is accomplished in consideration of the above problems, and an object of the present invention is to provide a straw with high value as a merchandise in which the above-­described air passage can be processed with better finish and an appearance in good balance as well so that it is possible to form an air passage of this type.
  • a square cylinder portion is formed in the longi­tudinal direction of the straw at a specified distance from the front end portion of the straw where the straw comes in sliding contact with the sealing film thereof, in which the cross section of the square cylinder portion in the ortho­gonal direction with respect to the axial line of the straw is a polygon having a small number of sides and the length of the outer periphery thereof is the length of the outer periphery of the body of the straw.
  • the polygon of the cross section of the square cylinder portion is a square, and in this case, it is recommended that the square is made into a rhombus and that one end of the edge portion of the short diagonal line be caused to position on the tip of the diago­nal end portion of the straw. It is advantageous, when using the straw, to form the circumferential wall in the expanded diameter portion which is on the opposite side of the front end portion of the straw with the square cylinder portion being disposed between the front end portion and the opposite side of the straw.
  • the gap between the straw and the inner edge of the circular residue of the broken pieces of the sealing film attached to the straw inserting opening becomes large in which even if large residual broken pieces of the sealing film attaching to the straw inserting opening exist, the gap is blocked only in part thereof, so that the air passage can be maintained by the gap of other broken sealing films thereby to balance the pressure inside and outside of the container while sucking to drink beverage.
  • the area becomes the smallest in the case of a regular triangle. Therefore, the gap becomes maximum so as to enable to form a large air passage. If in this case one end of the edge portion of a regular quadrangle is caused to position on the tip of the diagonal end portion of the straw, two gaps of the inner edge of the residual broken pieces of the sealing film can be positioned on the side of the tip where circular arc residual broken pieces is likely to be formed thereby efficiently forming the air passage.
  • the polygon of the cross section of the square cyl­inder portion is made a square, generally the area of the cross section of the same circumferential length is larger than the area of a triangular, and the area for sucking to drink beverage can be made greater even if the gap becomes small.
  • the square is made a rhombus and one end of the edge of the short diagonal line thereof is caused to posi­tion on the side of the tip of the diagonal end portion of the straw, the area for sucking to drink beverage can be made at least smaller than that of a regular square, that is, the gap can be made larger, so that the area for sucking to drink beverage can be made larger though the gap becomes smaller than that of the regular triangle.
  • the straw (3) is manufactured by partially forming under pressure a tube of a specified length and a specified diameter consisting of materials such as polypropylene and polythylene, and the front end portion of the straw (3) is cut diagonally to form a diagonal end portion (4).
  • the circumferential wall (6) of the straw (3) is formed under pressure so as to form the square cylinder portion (5) over a section where the straw disposed for sucking to drink beverage comes in sliding contact with the broken sealing film of the straw inserting opening, so that the section (cross section) in the diagonal direction with respect to the axial line of the straw (3) is made a regular triangle and further that one end of the edge portion of the regular triangle is positioned on the side of the tip (4′) of the diagonal end portion (4) of the straw (3).
  • Fig. 2 is the cross section of the line (A) - (A) of the straw (3) shown in Fig. 1 (a), and shows the relation where­in the circumferential wall (6) and the cross section is the square cylinder portion (5) of the regular triangle.
  • Fig. 3 is a perspective view show ing the using condi­tion of the straw (3) which is a first embodiment having the square cylinder portion (5) whose cross section is a regular triangle, wherein the straw (3) is inserted into the straw inserting opening (2) of the paper container in which liquid beverage is sealed.
  • Fig. 6 through Fig. 8 show a second embodiment and Fig. 6 (a), (b), and (c) are the front view, side view, and rear view respectively of the straw of the embodiment of the invention.
  • the square cylinder portion (5) whose cross section is a regular triangle shown in the first embodiment is formed into a rhombus whose angle of the cor­ner of thc acute angle is 60 degrees.
  • one end of the edge (whose angle is 120 degrees) of the short diagonal line of the rhombus is formed under pressure to as to position on the side of the tip (4′) of the diagonal end portion (4) of the straw.
  • Fig. 7 is a sectional drawing of the line B - B of the straw (3) shown in Fig. 6 (a) and indicates the relation between the circumferential wall (6) and the square cylinder portion (5) of the cross section of the rhombus.
  • the external air flows into the container as the beverage in the container is sucked for drinking thereby enabling smooth drinking.
  • the area of sucking for drinking is a little greater than that of the case wherein the cross section of the square cylinder portion is a regular triangle.
  • Fig. 9 and Fig. 10 show the straw of other embodiment
  • Fig. 9 is the front view of the straw
  • Fig. 10 is the plan view of Fig. 9 showing the relation between the inner wall of the square cylinder portion (5) and the side wall (6a) of the suction side of the straw.
  • an expanded diameter portion (6a) is formed by expanding the diameter of the circumferential wall (6) on the suction side which is opposite to the diagonal end portion of the straw with the square cylinder portion (5) of the straw (3) whose cross section is a regular triangle of the first embodiment.
  • the inner diameter portion of the straw inserting opening (2) of the paper container that is, the exposed sealing film (8)
  • the center of the square cylin­der portion (5) is eccentric on the opposite side of the tip (4′) of the straw from the center of the axis of the straw (3) and to cause one end of the edge of the square cylinder portion (5) to position on the side of the tip (4′) thereby forming a large air passage (7).
  • the straw according to the present invention has the following effects as described hereinafter.
