摘要： A molded plastic closure cap has a number of downwardly projecting fins on the underside of its cover for forming a seal with a container in combination with a liner positioned between the fins and the container rim. The liner is a laminated one consisting of a plastic foam layer engaging the fins, an adhesive layer engaging the package and a thin aluminum foil layer sandwiched between the foam layer and the adhesive layer.

摘要： A package comprising a container and a molded plastic closure. The container neck has external threads formed thereon and an external frustoconical sealing surface formed above said threads and extending upwardly and radially inwardly. The closure comprises a panel and an integral depending annular skirt, the skirt having integral internal threads formed thereon complementary to the threads on the neck of the container. An integral annular side sealing rib extends radially inwardly from the inner surface of the skirt and engages the external frustoconical sealing surface of the container in an interference fit such that when the closure is threaded on the container, the rib is compressed into sealing relation with the external frustoconical sealing surface. The panel portion of the closure includes a portion adapted to engage the end of the neck of the container to form a top seal. The closure includes a flexible annular wall integrally connecting the periphery of the panel and the sealing rib.

摘要： A closure cap particularly suited for use with containers such as milk bottles includes multiple sealing areas as well as frangible locking means. The locking means is located near the lower rim of a skirt portion of the closure cap. If the locking means has not been tampered with, an interlocking engagement between the locking means and a complementary portion of the container retains the cap on the container. If the locking means has been tampered with, the cap can be removed from the container. A visual inspection of the closure cap readily indicates whether the locking means is in tampered or untampered condition. In one embodiment, the cap can be repeatedly snapped into place on the container, and in other alternative embodiments, the cap can be repeatedly threaded onto the container. The multiple sealing areas not only seal the contents of the container, but one of the areas also prevents dust, dirt, or other contaminants from having access to the other sealing areas.
摘要翻译：特别适用于诸如牛奶瓶的容器的封闭盖包括多个密封区域以及易碎的锁定装置。锁定装置位于封闭盖的裙部的下边缘附近。如果锁定装置没有被篡改，则锁定装置和容器的互补部分之间的互锁接合将盖保持在容器上。如果锁定装置被篡改，则盖可以从容器中移除。封闭盖的目视检查容易表示锁定装置是否处于篡改或未受损的状态。在一个实施例中，帽可以重复地卡扣在容器上的适当位置，并且在其他替代实施例中，帽可以重复地螺纹连接到容器上。多个密封区域不仅密封容器的内容物，而且其中一个区域还防止灰尘，污垢或其他污染物进入其它密封区域。

摘要： A thermoplastic cap having improved anti-backoff characteristics features a primary helical thread and a coaxial secondary thread. The cap is of a thermoplastic material having an elastic modulus in flexure within the range of from about 0.2.times.10.sup.5 to about 10.sup.6 pounds per square inch so that the secondary helical thread will flex in response to tightening torque.

摘要： A polypropylene closure for glass containers. The enclosure has a top end wall and a depending annular skirt wall. A substantially rigid V-shaped sealing fin of triangular cross-section projects downwardly from the top end wall to engage the finish of a glass container neck in sealing relation when the closure is applied to the container. The closure is threaded onto the container neck and the sealing fin comes into contact with the finish. The application of additional closure torque causes the sealing fin to deform and be crushed.

摘要： A method for applying a threaded closure to a container, said closure having sealing means in or towards the crown thereof, which method comprises applying the closure to the container by the application of a predetermined rotary torque thereto, continuing the application of the closure to the container until the desired torque applied is obtained and thereafter applying axial pressure to the closure crown towards and on to the container while simultaneously applying said torque whereby the closure pressure serves to disengage the threads to overcome at least some of the friction therebetween to permit a greater proportion of the applied torque to be applied to the sealing means within the closure.

摘要： An improved seal between a flexible plastic container and its closure cap, wherein the cap is provided with an internal annular shoulder engaging the tapered side surface of an annular lip provided by the neck of the container. The shoulder bears inwardly against the lip with a force sufficient to flex that lip inwardly and maintain the same in a condition of stress. Ideally, the cap is formed of a plastic of limited heat shrinkability at autoclaving temperatures; therefore, heat sterilization of the sealed container and its contents results in slight contraction of the cap and further increases the integrity of the seal. Where the container is formed of plastic material capable of softening slightly at autoclaving temperatures, the shoulder tends to penetrate the lip to a limited extent during such autoclaving to create an undercut in the lip. Later, when the contents of the container are to be used, removal of the closure produces an audible click as the shoulder is drawn from the undercut, thereby indicating that the seal has been broken.
摘要翻译：柔性塑料容器与其封闭帽之间的改进的密封，其中所述盖设置有接合由所述容器的颈部提供的环形唇缘的锥形侧表面的内部环形肩部。肩部以足以使唇部向内弯曲并在压力状态下保持相同的力向内靠在唇部。理想情况下，盖子由高压灭菌温度下的热收缩能力有限的塑料制成; 因此，密封容器及其内容物的加热灭菌导致盖的轻微收缩，并进一步提高密封的完整性。在容器由能够在高压灭菌温度下稍微软化的塑料材料形成的情况下，在这样的高压灭菌过程中，肩部倾向于在有限的程度上渗入唇部，从而在唇部中形成底切。之后，当使用容器的内容物时，由于从底切中抽出肩膀，所以封闭物的移除会产生可听到的咔嗒声，从而表明密封件已被破坏。

摘要： A screw threaded cap for stoppering and re-stoppering of bottles enclosing gaseous beverages such as beer, has a base comprising a resilient lip adapted to co-operate with the junction of the bore of the bottle neck and its end surface. Ribs limit the distance between the latter and the corresponding surface of the base. The upper portion of the skirt has a rounded profile preventing cracks.
