Abstract

The utility model relates to an easy-to-open vacuum can with an impact preventing pressing ring, which is an easy-to-open food can composed of a sheet iron cover, a glass bottle, a rubber sealing ring, and an impact preventing pressing ring, wherein, the sealing ring is arranged between the cover and an internal mouth of the bottle. After the utility model is evacuated, the cover, the bottle, and the sealing ring are pressed into integration, and then, the external side of a bottle mouth is tightened and is provided with the impact preventing pressing ring which is provided with screw threads for forming a double sealing structure. When food is eaten, the pressing ring is downwards screwed, a cross-shaped groove on the cover is lightly pressed with a hard object, and the groove is cracked; the air can enter the bottle, and the cover can be automatically bounced. The easy-to-open vacuum can with an impact preventing pressing ring has the characteristics that the cover is easy to be opened, the bottle can be used for a plurality of times for reducing garbage, and the internal part of the utility model is vacuum and sterile.

Description

Easy-to-open vacuum can with impact-resistance pressing ring

The utility model belongs to tinned food container manufacture technology field.Vacuum easy open can with protecting against shock trim ring is that additional protecting against shock trim ring forms on the architecture basics of vacuum easy open can (No. the 60509th, Chinese utility model patent).The vacuum easy open can is proved to be in practice and can be used as the tinned food container application.

The utility model purpose is that under given conditions, for example: container is in spacecraft, in the time of in the contour acceleration in naval vessel, the fierce carrier that impacts, has designed the protecting against shock trim ring for guaranteeing seal of vessel.

This device is made up of (1) iron sheet lid (or vinyl cover), (2) glass bottle, (3) rubber seal ring, (4) protecting against shock trim ring.Lid can be designed to circular conical surface, plane or other curved surfaces with the bottle junction surface.Air is after lid and bottle mouth position are extracted out, and atm difference will be covered and bottle sealing mutually, and force localization is on the seal ring that places between lid and the bottle.(when the lid diameter was 6cm, its power was 24Kg).Because the existence of seal ring makes lid directly not contact with bottle.The bottleneck outside is shaped on screw thread, tightens protecting against shock trim ring (4) on it, and then trim ring is pressed on the upper edge of lid and by lid application force is added on the seal ring, thereby makes container obtain double seal.

The structure of protecting against shock trim ring (4) is to have the screw thread that matches with the bottleneck outside, and big hole is arranged in the middle of the trim ring.Core punching press at lid (1) has cross bath (5), and airtight before this groove is not stressed, its effect is when edible, screw off trim ring (4) earlier and use the hard thing of key one class again, gently press the cross recess top, groove is stressed squeeze crack, in the air admission bottle, atm difference disappears, and lid can be upspring voluntarily.

The utlity model has 1. lids and easily open, 2. glass bottle is convenient to reclaim repeated use, reduces the rubbish of contaminated environment.3. inner vacuum is aseptic, so adding preservative agent not, food is not perishable.4. there is not weld seam, so unleaded.

Claims

A kind of vacuum easy open can with protecting against shock trim ring, comprise iron sheet lid (1), glass bottle (2), rubber seal ring (3) and protecting against shock trim ring (4), it is characterized in that: the iron sheet lid is up big and down small truncated cone-shaped, place's punching press has cross bath (5) in iron sheet lid bottom centre, iron sheet cover the end have one be parallel to the bottom the upper edge, glass bottle opening is inboard to be circular conical surface with covering engaging portion, rubber seal ring (3) is arranged between the circular conical surface of iron sheet lid and bottleneck inboard, and there is screw thread the bottleneck outside and screws on the protecting against shock trim ring with macropore.
