Abstract

For the packing case of strip processed food such as usefulness such as ham, sausage and cheese, this applies mechanically the tubular film formation, and its two ends are sealed by tightening up, and small pieces Kaifeng band is welded in an end of blister-pack cover.When the Kaifeng band was opened from thin-film covering, breach just appearred in the welding position of packing film, so the blister-pack cover is easily from the upper dismounting of processing food.

Description

The packing case of strip processed food

The invention relates to and a kind ofly make and for strip processed food, for example the packing case used of ham, sausage and cheese by plastic sheeting; More particularly, be about taking off mouth by short Kaifeng band, the packing case of strip processed food usefulness.

For the strip processed food, the packing case of using such as ham, sausage and cheese is to be made by plastic sheeting such as vinylidene chloride.This plastic sheeting is rolled into cylindrical shape or tubulose, and two opposite side of film make it to interlink with ratio-frequency welding, and in the sleeve of then processed food being packed into, the two ends of sleeve metal filament banding is so plastic sheeting has just formed the packing case of processed food usefulness.

Because such blister-pack cover has been filled processed food, thus the space do not had, so that the blister-pack cover is difficult to open and remove; If with pocket knife and so on the part of blister-pack cover is cut open, then the blister-pack cover is easily opened from the position of being cut; But, if there is not on hand pocket knife, then be difficult to film dismantling.

For the little blister-pack cover that cheese is used, have the Kaifeng band along the total length of its blockade line, the two ends of Kaifeng band are fixed with hoop blister-pack and put.Then, Kaifeng band costliness is very uneconomic because common Kaifeng band along the total length outfit of packing case, therefore uses so long.When the total length along blister-pack cover is equipped with the Kaifeng band, because of its two ends are fixed on the packing film with hoop, so when the blister-pack cover was removed the Kaifeng band, processed food will be crooked, as long as the Kaifeng band is not opened the just difficult dismounting of packing film.In addition, because the total length setting along packing case is with in Kaifeng, therefore the design of this packing case can not be satisfactory.

The purpose of this invention is to provide a kind of blister-pack cover for package processing food, and only need just can easily the blister-pack cover be opened with a bit of Kaifeng band.

Another object of the present invention provides a kind of economy-size cover for package processing food, and this cover only uses the very Kaifeng band of segment.

Another purpose of the present invention provides a kind of good design that has, and is used for the packing case of package processing food.

Fig. 7 (H): the enlarged drawing of Kaifeng band assembling.This Kaifeng band is to extend to welding portion to bind round and be attached on the packing film;

Fig. 1 represents the packing case of sausage, this packing case is constructed as follows: plastic sheeting 1, for example 1, the film that the 1-dichloroethylene is made is rolled into tubulose, and 1 liang of opposite side of film formed shut line 2 with dielectric bonding, and will process the meat tubular film 1 of packing into then, tighten up at the two ends of tubular film 1, use hoop 3 bandings wiry again, so the film cover has just been sealed.

Kaifeng vertically is soldered to an end of film 1 with 4 along film 1, and Kaifeng is films of being made by resin film such as vinylidene chloride with 4, fixedly is attached on the surface of film 1 by local welding part 5.In concrete scheme shown in Figure 1, welding portion 5 is in the shape of the letter V in 4 zone in Kaifeng.Kaifeng is with binding round 3 it to be fixed to tightening up on the termination of film 1 with 4 right hand end among Fig. 1.

Fig. 5 and Fig. 6 represented film 1 before forming the sausage packing case, and Kaifeng is with 4 need be attached on it.As shown in Figure 5, before the processing meat of packing into, film 1 is plane, and the Kaifeng of small pieces then is attached on the film 1 with fixing spacing with 4.Utilize during operation hot sealing device with a slice Kaifeng with 4 two positions that are soldered to film 1.In Fig. 5 and 6, the weld zone 5 that is formed by hot sealing device is in the shape of the letter V.

The process of actual formation packing case as shown in Figure 5, after Kaifeng is with 4 to be attached to

film

1,1 liang of opposite side of film interconnects at blockade line 2 places (consulting Fig. 2) and forms sleeve pipe, its horizontal direction of axially pressing Fig. 5 is extended, insert then the meat of processing in the pipe, the two ends of tubular film 1 are tightened up, with hoop 3 pipe sealed again.Tubular film 1 and Kaifeng are with 4 to cut open along A-A line and B-B line, so an end is welded with the Kaifeng band, sausage packing case has as illustrated in fig. 1 and 2 just formed.More particularly A-A and B-B line surround the film of part among Fig. 5, be equivalent to form a film unit of a sausage packing case, moreover as shown in Figure 5, sever in the centre of two weld zones 5 with film 1 with 4 in Kaifeng, so Kaifeng is attached to an end of sausage packing case with 4 civilian dresses with 45 and Kaifeng of being severed half by the centre.

When packing film 1 need be opened, as shown in Figure 3, open an end that breaks a seal with 4 with hand, the weld zone 5 that is in the shape of the letter V also is with 4 to be opened with Kaifeng, so film 1 breach 10 occurs from weld zone 5.Therefore, if Kaifeng is opened such as the direction of Fig. 4 arrow indication with 4, breach 10 is increase just, so processed food such as sausage that film 1 just can fill in it are removed.

Fig. 7 (A) represents respectively that to Fig. 7 (H) Kaifeng is various shape with the weld zone 5 on 4.

The extended line of Fig. 7 (A) expression weld zone 5 is axial vertical with packing case 1.Fig. 7 (B) then represent the extended line of weld zone get packing case axially.Fig. 7 (C) and (D) explanation weld zone 5 be T font and X font respectively.Fig. 7 (E) illustrates that weld zone 5 is oblique.Fig. 7 (F) illustrates that welding portion 5 is in the shape of the letter V, and stretchs out to Kaifeng with 4 outside.The extended line that Fig. 7 (G) illustrates welding portion 5 is axial vertical with packing case 1, and extends to Kaifeng with 4 outside.If weld zone 5 is as Fig. 7 (F) and (G) time, Kaifeng is with 4 one to open, and not only the weld zone 5 with 4 occurs breach from Kaifeng, and also the weld zone 5 from film 1 produces, breach expands to film very soon, so only need use very little power just can remove film.In addition, the extended line of Fig. 7 (H) expression weld zone is got the axial of packing case 1.

In the present invention, although Kaifeng with 4 two ends that can be assigned in packing case, Kaifeng is provided to an end of processed food packing case with 4 need, film 1 just can be removed satisfactorily.Moreover the present invention also can use a kind of packing case 1, and its two ends can be sealed with ultrasonic wave, and needn't use hoop 3 devices.In this case, Kaifeng shown in Figure 1 can link together it and packing film 1 with super sonic with 4 right hand end, also can be attached to the enclosure portion of packing case 1 respectively.

As mentioned above, according to the present invention, the strip processed food such as the packing case of ham, sausage and cheese, only need be opened the Kaifeng band of small pieces and just can remove packing case. Because required Kaifeng band is small pieces and cheap, so cost is low; Because the Kaifeng band only fills the end that is attached to packing case, therefore do not affect the design of whole cover again.
