Provided is a twist-cut unsealing mechanism in which an operator can surely sense the fact that twist-cutting of a seal member has completed in assembling of spout and cap of such a type that a container is unsealed by twisting and cutting a seal member for the liquid passage of a spout by means of a cap. A twist-cut unsealing mechanism includes both-side protrusions arranged along a virtual circle rounding around the center line of rotation and an abutment protrusion movable relatively to the both-side protrusions along the virtual circle, and is configured so that one of the both-side protrusion and the abutment protrusion for indicating completion of twist-cut is fixed to a spout () and the other protrusion is fixed to a cap (), the both-side protrusion has a sliding surface of gentle slope and a stopper surface of steep slope wherein projection heights of both surfaces are substantially same in the radial direction and both surface are adjacent to each other along a circle, the abutment protrusion can abut against the sliding surface and the stopper surface, and at a position where the abutment protrusion passed the sliding surface in the rotational direction, the relative rotation positions of the spout () and the cap () is set above the twist-cut completion position of a seal member () and within detachment allowance positional range where the detachment of the cap () is permitted.

Twist-cut unsealing mechanism for container

A pouring member includes an unsealing cap and at least two rotation prevention sections extending vertically and downwardly from an end surface of an open end side of the unsealing cap and is arranged such that the at least two rotation prevention sections are apart from one another by an angle which is larger than a rotation angle required for twisting off the sealing part, and symmetrically with respect to the central axis of the unsealing cap. A recess is formed such that the recess opens to a front end side of the rotation prevention section, and an engagement projection engages the recess in a direction substantially parallel with a direction in which the rotation prevention sections are extended vertically and downwardly, and is formed at a specific position of the flange part of the pouring member.

Pouring member

Provided is a containerfor inspection which stores and pours out contents therein, and the container is provided with a container main bodyhaving a mouth portionformed thereon, a cover portionattached to the mouth portionto seal the container main body, and an opening capattached to the cover portion. The cover portionhas a closing wallfor closing the mouth portion, and the opening capis provided with an pouring outlet, and a cutting portionfor cutting the closing wall. When the opening capis attached to the cover portion, the cutting sectioncuts the closing wallto enable pouring out the contents. Thus, in the provided containerfor inspection, sealing properties of the container main bodyare ensured by the cover portion, and the closing wallof the cover portionis cut by the opening capattached to the cover portionwithout removing the cover portion, whereby the contents can be poured out.

Label applying apparatus of rotary blow molding machine

In a delivery apparatus in a machine for preparing hollow vessels by delivering mandrels supporting thereon preforms and vessels through a preform-heating zone and a draw-blow-forming zone, the downward movement of a mandrel-clamping mechanism is utilized for insertion of a preform into the mandrel and the rising movement of the clamping mechanism is utilized for withdrawal of a formed vessel. By this arrangement, insertion and fixation of preforms into mandrels and withdrawal of formed vessels from mandrels can be performed continuously, assuredly and smoothly in one apparatus while saving the waste in the blow-forming operation. If the operation of reversing the clamping mechanism is added, any particular device need not be disposed for reversing preforms.

Delivery apparatus in machine for preparing plastic hollow vessels

An apparatus for preparing a drawn heat-set plastic hollow vessel, which comprises a rotary member having a plurality of openable-closable blow-forming and heat-setting molds and preform-supporting mechanisms corresponding to said molds, a preform supply mechanism for supplying a preform maintained at a drawing temperature into the mold of the rotary member at the opening position and a vessel withdrawal mechanism for withdrawing a drawn and heat-set vessel from the mold of the rotary member at the opening position, wherein the rotary member comprises a mold-heating mechanism for maintaining the molds at a heat-setting temperature through the entire rotation course of the rotary member, an opening and closing mechanism for closing the molds after passage through the position of the preform supply mechanism and opening the molds before arrival at the position of the vessel withdrawal mechanism, a sealing member capable of reciprocating relatively to the preform supported by the preform support mechanism while having a sealing engagement with the mouth portion of the preform, a hollow drawing rod arranged concentrically with the sealing member to reciprocate so that the drawing rod is inserted into the preform and drawn out therefrom.
