A container, capable of construction from polymeric injection molding, comprising a plug and ring closure, the plug having first and second locking arms for extending into the ring, each locking arm having a locking tab located adjacent to a distal end for selectively securing the plug within the ring when the locking tabs reside within an undercut of the ring.

A plastic container with a snap lid and with a snap element is provided on the upper edge region of the container for the lid to snap onto, where the lid has a circumferential sealing web projecting downwards that contacts the inside of the container, where at least one projection that extends in an essentially radial and essentially vertical direction is provided on the lid radially inside the sealing web. To provide a plastic container with snap lid, which fulfils the special demands imposed on leak-proofness, while simultaneously providing high load-bearing capacity, the vertical extension of the area of the projection adjacent to the sealing web is small relative to the total vertical extension of the projection The inward-facing projection can be located on an inside circumferential edge integrally molded on the sealing web. In addition to the sealing web, another circumferential seal is provided in the region of the top edge of the container.

The neck of a container has a smooth seal surface engaged by the inner skirt or plug of a cap. Such surface is free of trim and parting line flaws which are characteristic of blow-molded jars because the surface is formed in such a way that the seal surface is not in contact with mold parting lines and further the trim (excess plastic) of the neck is located away from the sealing surface. In one form of the disclosure, above the sealing surface the neck wall slants outward and then bends upward-inward in a short, tapered stretch which engages the underside of the cap disk to compress against the disk or a liner or foil. Other forms of seal surfaces are disclosed. The exterior of the neck is formed with screw threads which engage threads on the interior of the outer skirt of the cap. Caps suitable for combination with the neck, methods of forming the neck and mold apparatus for forming the neck are also disclosed.

The neck of a container has a smooth seal surface engaged by the inner skirt or plug of a cap. Such surface is free of trim and parting line flaws which are characteristic of blow-molded jars because the surface is formed in such a way that the seal surface is not in contact with mold parting lines and further the trim of the neck (excess plastic) is located away from the sealing surface. In one form of the disclosure, above the sealing surface the neck wall slants outward and then bends upward-inward in a short, tapered stretch about 18° to the horizontal which engages the underside of the cap disk to compress against the disk or a liner or foil. In another form of the invention, above the seal surface the neck extends outward and then upward and then inward in a flange which is trimmed along a line which has a circumference no less than the circumference of the seal surface. The exterior of the neck is formed with shoulders which engage over locking beads on the interior of the outer skirt of the cap.

A wide mouthed container of synthetic resins for a paint, wax and the like, formed thinly in the body portion thereof by injection stretch blow molding is provided. A mouth portion of the wide mouthed container is of large diameter and comprises an internal wall integral with a body portion having a bottom, a belt shaped external wall integrally formed on the outside of the internal wall via a joint portion of required width to be in H-shape, and an upper and lower annular grooves between both the walls sectioned by the joint portion. The body portion is stretch blow molded thinly from the underside of the internal wall to a position where the lower edge of the external wall touches the body portion to form the side surface of the body portion on the same level as said external wall and to form the lower annular groove into a hollow in the lower part of the mouth portion. A plurality of ribs for preventing the deformation of the joint portion in stretching the body portion are integrally formed aslope onto a corner between the under surface of said joint portion at its external wall side and the inner surface of the external wall to provide a required number of the ribs in the lower annular groove at a regular interval.

The present invention discloses a novel frozen dessert container. A preferred configuration for the frozen dessert container is a super-ellipse configuration. The invention allows for registered offset printing on the rim of the lid. The invention also allows for use of a single material for an entire frozen dessert container. The frozen dessert container may be composed of a fiberboard material with a polyethylene coating thereon. The present invention allows for the cost-effective fabrication of a frozen dessert container having a non-circular cross-section. The invention allows for greater sealing between the lid and the cup of the frozen dessert container.

A plastic bucket includes at least one undercut adjacent an upper end of the bucket defined by a bucket wall which extends upwardly and inwardly along a diagonal path. An annular, vertical section may be provided at the upper end of the diagonal path. Above the vertical section, the bucket wall extends radially outwardly to create an annular, horizontal flange. In addition, an uppermost annular rim may extend upwardly from the horizontal flange and be located approximately midway between inner and outer radii of the flange.

It is related to an improved box opening/closing structure for storing wet towels for baby. It mainly comprises a box for storing wet towels, a box cover fitted on the box and a lifting cover disposed on the middle of the box cover. When a user wants to open it, just press on the lifting cover, this lifting cover can be opened. When this user wants to close it, just make the lifting cover rotate down and then the lifting cover will be locked with box cover. Therefore, not only an excellent sealing effect can be obtained but also the moisture of the wet towels stored in the box can be kept.

A child-resistant compact or tablet case of one-piece molded plastic construction made up of a generally flat rectangular base and a cover top interconnected by an integral "living" hinge. A pair of mating lip flanges extend one each along the front edges of the base and top, i.e., the edges remote from the hinge. Each flange has an arcuate recess, and these recesses are mutually offset from each other laterally of the case when it is closed with the flanges lying against one another. By placing a thumb in one recess, and the tip of the forefinger in the other recess, a pry-open force may be applied to thus readily open the case. Since only one recess is visible when viewing the case from the top or the bottom, this manner of opening the case is not readily apparent to an infant or young child, but is very easy for an infirm or elderly adult to comprehend and use for opening the compact case merely by finger feel. In addition, the base has a pair of latch spring fingers disposed one on each of the laterally opposed sides near the front edge of the base and that protrude upwardly from the base bottom wall in cantilever fashion. The top has a cooperating pair of pockets that receive the free latch-tang ends of the spring fingers to render them exterior-accessible in the closed condition of the case. The outer edges of these pockets form the strike portion of the latch system. To open the case, squeeze pressure must be applied with one hand simultaneously to both of the spring finger tang ends to move them to unlatched condition, and then to hold them in this condition while, also simultaneously, with the other hand pry-open pressure is applied to the two front lip flanges at the aforementioned offset recesses. This two-handed operation further resists opening by a child because of its complex dual-hand-manipulative coordination requirement.

An improved deep wiper closure for open head shipping containers wherein the closure exhibits an upwardly opening channel in the closure structure between a wiper wall and a riser wall, the riser wall connecting the wiper wall with a planar central panel of the closure. Angled ribs, each preferably integrally attached to only one of the walls, are disposed in the channel to provide controlled flexure between the walls under extreme side impact conditions.
