Definitions

  • This invention relates to a blow-moulded bottle-shaped container of biaxially-oriented synthetic resin such as polyethylene terephthalate resin.
  • bottle-shaped containers of relatively large size for containing liquids such as, for example, liquors or soy sauces have been widely utilized.
  • the most effective means for moulding a bottle-shaped container of this type include means for moulding the bottle-shaped container by biaxially orientation blow-moulding a preformed parison moulded from a synthetic resin material.
  • a blow-moulded bottle-shaped container of biaxially-oriented polyethylene terephthalate resin has a number of advantages such as a light weight, excellent mechanical strength and physical properties, an inexpensive cost together with the possibility of mass production.
  • the blow-moulded bottle-shaped container of biaxially-oriented synthetic resin of this type has a round configuration as a whole with a smooth surface and is moulded in a relatively large size, the bottle-shaped container tends to feasibly slip when held by a hand and is accordingly inconvenient to be grasped by the hand, and must be associated with a grip separately moulded as a holding means of the container body.
  • axially slender recesses have been manufactured at both sides of a cylindrical body of the bottle-shaped container so as to utilize the rear halves of the container body as a grip.
  • the above-mentioned conventional bottle-shaped container is certainly convenient to handle but does not always have sufficient mechanical strength. More specifically, the conventional bottle-shaped container of this type exhibits serious drawback so that, when the conventional bottle-shaped container is dropped in the state that a predetermined quantity of liquid is filled in the container body to conduct a strength test, the slender recesses formed on the body of the bottle-shaped container are externally projected and deformed by the internal pressure of the liquid container in the container body by the dropping impact, resulting in no recovery of the deformation.
  • this external projecting deformation of the recesses on the body of the conventional bottle-shaped container means insufficient buckling strength of the recesses formed on the container body, whereas the bottle-shaped container is desired to provide high mechanical strength.
  • EP-A-0 033 745, FR-A-934 609 and US-A- 1 602 391 constitute improvements over the container described above with its axially slender recesses.
  • EP-A-0 033 745, FR-A-934 609 and US-A- 1 602 391 constitute improvements over the container described above with its axially slender recesses.
  • From this prior art it is known to provide a pair of inwardly depressed recesses in the cylindrical wall of the cylindrical body at opposite sides thereof with the minimum spacing between the recesses being at their deepest parts so that a portion of the cylindrical wall between the recesses forms a grip as a result of the recesses, but even this form of container does not have sufficient strength against buckling when the container is filled with liquid and dropped.
  • the present invention seeks to overcome this drawback, and according to the invention this is achieved with a container having the characterising features of claim 1.
  • Preferred features of the invention are set forth in sub-claims 2 - 4.
  • the reinforcing rib or ribs thus provided on the container effectively disperse the internal pressure acting on the recesses.
  • FIGs. 1 and 2 show an embodiment of a bottle-shaped container according to the invention.
  • a bottle-shaped container 21 has a cylindrical container body 22 in which the lateral cross-sectional shape thereof is formed substantially in a rectangular shape, and a neck 23 integrally moulded through a shoulder at the top of the container body 22.
  • Recesses 24 formed on opposite cylindrical surface portions of the container body 22 are respectively depressed inwardly toward a deepest body surface portion 25 at the centre thereof via inclined tapered walls 26 at the periphery thereof.
  • a pair of the recesses 24 are formed as described above on the opposite cylindrical surface portions to thereby cause the rear parts of the container body 22 to become a grip 27 of an axial strip shape.
  • a plurality of lateral grooves 29 are formed at a predetermined interval in parallel on the rear peripheral wall of the grip 27. The lateral grooves 29 thus formed provide mechanical strength of the grip 27, i.e., sufficient resistance strength against the grasping force of a hand acting on the grip 27 so as not to deform the grip 27.
  • one or more reinforcing ribs 28 of projecting strip shape are respectively formed laterally in the recesses 24 to cross the recesses 24 in such a manner that the ribs 28 are projected from the peripheral walls 26 of the recesses 24.
  • two reinforcing ribs 28 reinforce the recesses 24 having long elevational height.
  • the number of the reinforcing ribs 28 in the recesses 24 may be selected depending upon the degree to be reinforced of the recesses 24.
  • two reinforcing ribs 28 are spaced at such an interval that a finger of the hand can be inserted, thereby performing the anti-slip effect by the reinforcing ribs 28.
  • the projecting state of the reinforcing rib 28 may be any of linear and externally swelling state and that both ends of the reinforcing ribs 28 may be disposed in the vicinity of the depression starting portion of the recesses 24 from the tapered wall 26 so as to increase the projecting height width as much as possible.
  • the position of the projecting end must not be a value such that it projects from the plane shape of the cylindrical body surface of the entire container body 22, i.e., a value larger than the depth of the recesses 24.
  • the projecting height width of the rib 28 may be preferably set to a value equal to or near the depressed depth width of the recesses 24.
  • the reinforcing ribs 28 are moulded to cross the recesses 24 in a projecting strip shape in a relatively high projecting width. Therefore, sufficiently high mechanical strength can be provided in the recesses 24. Thus, even if internal or external pressure is acted on the recesses 24, the recesses 24 are not externally transferred, bent, projected nor deformed by the internal pressure, and the recesses 24 may not be further depressed nor deformed by the external pressure.
  • the reinforcing ribs resist against the internal and external pressure acting on the recesses. Therefore, the recesses of the bottle-shaped container are not bent, projected nor deformed towards the outside or inside, and the machanical strength of the entire bottle-shaped container can be largely enhanced. Also, since the grip is integrally moulded with the container body, a relatively large-sized bottle-shaped container body can be readily handled.
